FIELD OF THE INVENTION

The present invention relates to a case for computer and method of producing the case, especially a case for computer that enables a user to freely modify the design of the case as desired, and method of producing such a modifiable case.

BACKGROUND OF THE INVENTION

Conventional computers are described in many publications of patents or utility models. These computers are selectively equipped, so as to ensure the computer's performance, with (1) a power source, (2) printed circuit boards, (e.g. mother board on which CPU are installed), (3) internal storage modules such as a HDD (hard disk drive) and the like, and (4) external storage modules such as an FDD (floppy disk drive), a CD (compact disk) drive, a DVD (digital versatile drive), an optical disk drive, a smart card and the like; and these devices are arranged in the computer's case. Such a case for a desktop-type or tower-type computer typically has a standard shape and size, and such cases have been designed by manufacturers with mass production and economic efficiency in mind. (See Patent Documents 1 and 2.)

Patent Document 2:

Japan Utility Model No. 3066596

As described above, conventional computers have only standard functions because the components are assembled in cases whose shapes and sizes are determined by manufacturers. Therefore, when adding an additional component, such as a disk-drive, to a computer, the computer needs to be connectedâ€”either by a wire or wirelesslyâ€”to said component that can provide such additional functions. This results in the problem of peripheral components being scattered around the computer, which requires a large space and can causes a mess on the desk.

The exterior of a conventional case cannot be modified because it has a standard shape and size. Thus, a user cannot have a design that he or she desires, which is unsatisfactory. Moreover, because the exterior of the case has a standard shape and size, a large package, and thus a large space, are needed for transportation, resulting in high transportation costs.

The present invention solves the above problems. The objectives of the present invention are to provide a light and compact case for computer and methods of manufacturing said case, allowing a user to freely design the case, to easily assemble and disassemble it, and to freely add any components to it without resulting in a messy desktop or requiring a bulky package for transportation.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Preferred embodiments of the present invention will now be described with reference to the drawings.

The first embodiment of the present invention is a middle-tower-type case for computer, which consists of three unit cases: a first unit case 101, a second unit case 102, and a third unit case 103, as shown in FIGS. 1 through 6. Unit cases 101, 102, and 103 constitute a case for computer.

The first unit case 101 houses, as shown in FIGS. 3 and 7, external storage modules 104 (e.g. 5-inch disk drive) and 105 (e.g. 3.5-inch disk drive), and a board (such as a motherboard), an audio card, a video card, and other devices (not shown) for a PC. The second unit case 102 houses a power module 109 (see FIG. 17), and the third unit case 103 houses internal storage modules such as hard disk drivea 110 (see FIG. 19).

The first unit case 101, as shown in FIGS. 1 and 2, has horizontal place parts (outer panels 37, 39) that are parallel to each other but arranged at different heights on the case's rear side. The second unit case 102 is positioned atop lower place part (outer panel 37), while the third unit case 103 is positioned atop higher place part (outer panel 39). Also, part of the third unit case 103 sits atop the second unit case 102. In this arrangement, the outer surfaces of the second unit case 102 and the third unit case 103 align with both of the side surfaces (outer panels 33, 34) of the first unit case 101, while the top panel (outer panel 42) of the first unit case 101 and the upper panel (outer panel 20) of the third unit case 103 are aligned on the same level. Therefore, the whole case becomes a tower-type computer having an exterior that has a rectangular parallelepiped shape. In such an arrangement, in which the second unit case 102, which contains the power module 109, and the third unit case 103, which contains the internal storage modules 110, are positioned to the rear of the first unit case 101, the second and the third unit cases are not viewable from the front of the computer, which improves the appearance of the case, and heat from the power module 109 and the internal storage module 110 is emitted to the rear of the case.

The outer panel 5 of one side of the second unit case 102 that houses the power module 109 is made of punching metal, and the outer panel 7 on the back side of the second unit case 102 has an exhaust opening 7a. Air comes into the second unit case 102 via the outer panel 5 and goes out via the opening 7a, resulting in good dispersal of heat. The outer left-side and right-side panels 16 and the upper panel 20 of the third unit case 103 that houses the internal data-storing devices 110 are made of punching metal, also resulting in good dispersal of heat.

External storage modules 104 of the first unit case 101 are 5-inch disk drives (e.g. a CD/CD-RW drive, a DVD drive, an optical disk drive, and the like), while external storage modules 105 are 3.5-inch disk drives (e.g. floppy disks drive and the like) that are installed under the external storage modules 104. In order to house the external storage modules 104 and 105, the first unit case 101 is provided with external storage module bays (not shown) at the appropriate places. In FIG. 7, 101a is a board bay for housing boards (including the motherboard) and other devices for PC.

At the front of the first unit case 101 are properly installed a main switch 51 for turning on the computer, a reset button 52 for restarting the computer, and indicator lamps (LED) such as a power indicator lamp and an access lamp. At the rear of the first unit case 101 are connectors 106 to communicate with the power supply, a display, a scanner, other computers and other electronic devices.

FIG. 7 is a perspective view that shows a first unit case 101 in a state of assembly and disassembly.

The first unit case 101 comprises a frame member 101f onto which a plurality of outer panels 33, 34, and 36-43 are affixed so as to cover outside of said first unit case 101. The frame member 101f is formed to be outline (outer shell) of a solid shape of the first unit case 101 and by installing the outer panels 33, 34, and 36-43 on the frame member 101f, the unit case 101 is made to have an exterior as shown in FIG. 2. The outer panel 43 serves as a front cover (front panel) of the computer, and windows 43a and 43b, which provide access to the external storage modules 104 and 105, are formed so that their positions align with those devices.

FIG. 8 shows, in a state of disassembly, the frame member 101f, which is formed by assembling a plurality of inner frames 21-30, a plurality of corner parts 53, 55, and a plurality of outer frames 57-60, and 69-80, with said assembly accomplished by using screws.

The inner frames 21-30 are formed to be outline of each plane of the solid shape of the first unit case 101. For example, the inner frames 21 and 22 of the first unit case 101 are formed as sides having two steps each so as to be arranged at two step sides of the first unit case 101. The inner frame 23 is arranged at the front of the first unit case 101, and it has a rectangular shape and openings at positions that align with the external storage modules 104 and 105. The inner frame 29 is arranged at rear of the first unit case 101, where connectors 106 (see FIG. 6) are arranged, and it has an approximately L-shaped outline that corresponds to the back side of said first unit case 101.

The corner parts 53 are arranged at the corners of the solid shape that is formed by the inner frames 21-30, and the corner parts 53 connect the adjacent inner frames 21-30 to one another. The outer frames 57-60, and 69-80 that bridge the corner parts 53 or 55 and are affixed to the outside of the inner frames 21-30. Screws are used for installing the inner frames 21-30, the corner parts 53, and the outer frames 57-60 and 69-80 to one another, whose assembly is described below with reference to the drawings.

The inner frames 21, 22, and 23 are shown in FIGS. 9 through 11, and are formed in shapes of outline of the planes at the corresponding position to be arranged as described above. Holes 21b, 22b, and 23b at the corners of their respective inner frames 21, 22 and 23 are through-type, and their neighboring holes 21a, 22a, and 23a are tapped-type.

The corner parts 53 have three contact sides that meet at right angles as shown in FIG. 12. The inner frames 21-30 contact inside surfaces 53b of the corner parts 53. Through-type holes 53c are formed on the contact sides of the corner parts 53, and said holes are aligned with the tapped-type holes described above (e.g. 21a-23a of the inner frames 21-23). The adjacent inner frames 21-30 are affixed to one another by inserting screws through the corresponding holes. A tapped-type hole 53d is formed at the corner of the contact side and is used for affixing the outer panels. The outside surfaces 53a contact the outer panels 33, 34, and 36-43, as will be described later.

FIG. 13 shows an outer frame 57, whose length corresponds to the position where it is to be affixed to the inner frame 23, and at whose ends in the longitudinal direction are through-type holes 57c for screws to penetrate. Corner parts 53 are located at both ends of the outer frame 57. Thus, the outer frame 57 is affixed to the outside of the inner frame 23 by being flanked by the corner parts 53. Through-type holes 57c described above are aligned with the remaining tapped-type holes 23a of the inner frame 23 (FIG. 11) so that the outer frame 57 can be affixed to the inner frame 23 by inserting screws through the holes.

The other outer frames 58-60 and 69-80 have the same structure as the frame member 57, and they are affixed to the outsides of the corresponding inner frames 21-30.

The first unit case 101 contains external storage modules 104, 105, and therefore installation panels 45, 46, and 64 (in FIG. 8) are provided for installing said moludes. The installation panels 45 and 46 are formed in the shape of a â€œUâ€ and are attached to the corresponding inner frames by using screws or hooks so that the lower external storage modules 105 are affixed to the installation panel 45 and the upper external storage module 104 are affixed to the installation panel 46.

The installation panel 64 is a PC board base onto which a board (such as a. motherboard) is affixed, and is attached to the inner frame 21 after the board is affixed. The installation panel 64 has convex-shaped female-screw supports 64b, as shown in FIG. 14, that are formed on the inner frame 21 side and that receive male screws so as to screw a board (such as a motherboard) onto said installation panel 64. Therefore, the inner frame 21 of this embodiment serves as an installation panel. For this purpose, on the inner frame 21, as shown in FIG. 9, guides 21c and 21d, which are alternately arranged in the vertical direction, are arranged in both right side and left side. The guides 21c and 21d have different heights and their edges are bent. The installation panel 64 is inserted from rear of the inner frame 21 (rear of the first unit case 101) through the space between the back plane of the edge of the upper guide 21c and the surface of the lower guide 21d, and said installation panel 64 is finally affixed to the inner frame 21 by using screws. Bent guides 21e are arranged at the rear tip of guides 21c for making it easy to insert the installation panel 64.

The outer panels 33, 34, and 36-43 are affixed to outside of the frame member 101f as shown in FIG. 7. The outer panels 33, 34, and 36-43 are affixed to the outside of the outer frames 57-60, 69-80, and the corner parts 53, and through-holes are formed for decorative screws 61, as shown in FIG. 16, to penetrate. The through-holes 43f are formed so as to face to the tapped holes 53d of the corresponding corner parts 53, when the outer panels 33, 34, and 36-43 are to be affixed to the frame member 101f, and shown in FIG. 15, through-holes 43f are formed at the four corners of the outer panel 43 that serves as the front cover.

The decorative screws 61, whose heads 61a are processed so as to have an uneven surface so as to prevent their slipping, are used for affixing the outer panels via a screw part 61b that extends from the head 61a. The outer panels 33, 34, and 36-43 can easily be affixed by arranging the outer panels to contact the outsides of their corresponding outer frames, then inserting the decorative screws 61 into the through-holes and into the tapped holes 53d of the corner parts 53.

The first unit case 101 has a structure such that the frame member 101f, which is outline of the solid shape of the first unit case 101, is formed by assembling the inner frames, the corner parts, and the outer frames, then the outer panels are attached to the outside of the frame member 101f by screws. Therefore a user can easily assemble and disassemble the first unit case 101.

FIG. 17 shows a disassembled second unit case 102 that houses a power module 109. Six outer panels 5-10 are affixed to outside of a frame member 102f. A power component bay 102a, for housing the power module 109, is formed in the second unit case 102. An installation panel 4 is affixed onto the lower outer panel 8 so that the power module 109 can be affixed on top of the installation panel 4 by using screws. In this embodiment, the power module 109 is a rectangular parallelepiped, and therefore the frame member 102f is formed in such a manner that the power component bay 102a also is a rectangular parallelepiped.

FIG. 18 shows the frame member 102f of the second unit case 102 in a disassembled state. The frame member 102f comprises (1) six rectangular inner framesâ€”two each of 1, 2, and 3â€”each of which forms one side of rectangular parallelepiped, (2) a plurality of corner parts 53 for connecting adjacent inner frames (inner frames 1 and 2, for example) to one another at the corners of the inner frames, and (3) a plurality of outer frames 73, 75, and 79, which are affixed to the outside of the inner frames 1, 2, and 3.

The structure of the frame member 102f concerning assembly of the inner frames, the corner parts, and the outer frames is the same as that of the frame member 101f. Therefore, assembly and disassembly of the inner frames, the corner parts, and the frame member is done easily by using screws

The second unit case 102, whose exterior is a rectangular parallelepiped, is formed in such a manner that the outer panels 5-10 are affixed to the outside of the frame member 102f. Decorative screws 61 are used to affix the outer panels 5-10 to the second unit case 102, in the same way as the first unit case 101.

FIG. 19 shows a disassembled third unit case 103. The third unit case 103 is formed by installing six outer panels 16, 17, 19, 20, 34, and 40 on the outside of an frame member 103f. The third unit case 103 includes a internal storage modules bay 103a for housing internal storage modules.

In the internal storage modules bay 103a, for instance, three internal storage modules 110, such as hard disk drives, can be vertically installed. For that purpose, three installation panels 12 (See FIG. 20) are affixed inside the frame member 103f by using screws. As shown in FIG. 20, a fixing panel (an installation panel) 11 is provided to each installation panel 12 so as to affix the internal storage module 110 by using screws. In this embodiment, the internal storage module 110 is a rectangular parallelepiped, and thus the frame member 103f is formed so that the internal storage module bay 103a also will be a rectangular parallelepiped.

FIG. 20 shows the frame member 103f of the third unit case 103 in a disassembled state.

The third unit case 103 comprises (1) six rectangular inner framesâ€”two each of 13, 14, and 15â€”each of which forms one side of rectangular parallelepiped, (2) a plurality of corner parts 53 for connecting adjacent inner frames (inner frames 1 and 2, for example) to on another at the corners of the inner frames, and (3) a plurality of outer frames 71, 73, and 77, which are affixed to the outside of the inner frames 13, 14, and 15. The structure of the frame member 103f concerning assembly of the inner frames, the corner parts, and the outer frames is also the same as that of the frame member 101f. Therefore, assembly and disassembly of the inner frames, the corner parts, and the frame member is done easily by using screws

The third unit case 103, which has a rectangular-parallelepiped shape, can be formed by affixing the outer panels 16, 17, 19, 20, 34, and 40 on the outside of the frame member 103f. Decorative screws 61 are used to affix the outer panels 16, 17, 19, 20, 34, and 40 to the third unit case 103, in the same way as the first unit case 101.

The first unit case 101, the second unit case 102, and the third unit case 103 described above can be formed by using screws to assemble together inner frames, corner parts, and outer frames, thus first forming frame members, to the outside of which outer panels can be mounted, thereby forming said unit cases 101, 102, and 103, which are easy to assemble and disassemble.

Therefore, a user can freely and enjoyably select and change the design of his or her case for computer by selecting appropriate parts of frame members and then outer panels thereon. When adding an additional module, both the parts of the frame member and the outer panels to be mounted thereon can be selected so as to fit the shape and size of the additional module, so that such additional module can easily be assembled together in a case for computer, avoiding a messy desktop. Further, because the case can easily be disassembled, a bulky package is not needed to transport the computer, which facilitates transportation.

Next, a second embodiment of the present invention shows its application to a full-tower-type computer, and in the second embodiment, shown in FIGS. 21-23, a case 200 comprises of a case for computer by itself. In the description that follows, the directions of left and right refer to the left and right sides of the case, as viewed from the front of the case.

FIG. 21 is a perspective view of the case for computer 200 from the front side, showing the case with the outer panels partly removed. FIG. 22 is an enlarged view of the main part of the case (the disk-drive bay), and FIG. 23 is a front view of the case.

The case 200 houses large external storage modules such as 5-inch disk drives 310, small internal/external storage modules such as 3.5-inch disk drives 330 and 320, a motherboard bay 440 that contains boards including the motherboard, and other devices (not all shown) for PC, as shown in FIG. 21. The case 200 also houses the power module 350 and fan module 360.

At the front of the case 200, a SW-LED panel 250 is arranged in such a manner that switches, such as a main switch to start the computer and a reset button to restart it, and indicators such as a power indicator and access lamps are properly arranged. Also, at the rear of the case 200, a rear connector panel 241 is arranged in such a manner that connectors that can be connected with a power supply, a display, a scanner, other computers, and electronic devices for communication and the like, are arranged.

The case 200 comprises a frame member 210 and a plurality of outer panels affixed on the outside of the frame member 210 so as to cover them. FIG. 21 shows, as outer panels, a bottom panel 220, a rear panel 230, and a left-side panel 240, with other outer panels, such as front panel, right-side panel, and top panel, removed.

The frame member 210 is formed to be outline (outer shell) of a solid shape of the case 200. The case 200 becomes a rectangular parallelepiped when a plurality of outer panels 220, 230, 240 and others are affixed to the outside of the frame member 210, as shown in FIG. 21.

The frame member 210 is formed by using screws to assemble together a plurality of outer frames and a plurality of corner parts 211. In this embodiment, the frame member 210 is easily formed so as to directly connect a plurality of the outer frames with the corner parts by using screws (i.e. inner frames of the first embodiment are omitted in this embodiment), resulting in easy disassembly.

The outer frames form outline of the sides of solid shape of the case 210. Each of the outer frames has a quasi-angular shape similar to that of the outer frame 57 of the first embodiment that is shown in FIG. 13, for instance.

The corner parts 211 are located at the corners of the solid shape formed by the outer frames, and said corner parts 211 connect adjacent outer frames to one another. Only screws are used to attach the corner parts 211 and the outer frames to one another. The structure will now be described with reference to the drawings.

Both ends of the outer frames have through-holes (which correspond to holes 57c in FIG. 13, for instance).

FIG. 28 shows two views of a corner part of this embodiment: (a) is a perspective view from the outside, and (b) is a perspective view from the inside.

The corner part 211 has contact faces that have three orthogonal steps, as shown in FIG. 28 (a). The contact faces having such steps are formed in such a manner that the upper contact faces 211d, 211e, and 211f, which are the upper steps on the side of an orthogonal meeting point (mounting part), are respectively followed by lower contact faces 211a, 211b, and 211c, which also have an angular shape. The lower contact faces contact the inside planes of the outer frame (57b in FIG. 13, for instance). Each of the angle planes of the lower contact faces 211a, 211b, and 211c has a tapped hole with which the through-holes (57c in FIG. 13, for instance) of the outer frames described above are aligned, and through which screws are inserted so as to affix the adjacent outer frames to the corner parts 211.

The upper contact faces 211d, 211e, and 211f contact the outer panels 220, 230, 240 and other outer panels. Each of the upper contact faces 211d, 211e, and 211f has tapped hole(s) 211h, which are used to affix the outer panels. (See FIG. 22).

Each of the outer frames has a length that corresponds to outline of each side of the solid shape of the case 210. Other outer frames have the same structure as the aforementioned outer frame has and each is connected with the corresponding corner parts 211.

As shown in FIG. 21, the case 200 houses a disk-drive bay 300, in which a plurality of large/small disk drives 310, 320, and 330 are installed as internal/external storage modules in a stacked, united form. In this respect, the structure differs from that of both a conventional personal computer and that of the first embodiment, in which the internal storage modules bay for such as hard disk drives are housed separately from the large/small external storage modules bay. Therefore, the disk-drive bay 300 offers greater space economy than a conventional internal/external storage modules bay does.

As shown in FIGS. 21-23, the disk-drive bay 300 comprises:

(1) a pair of left-side and right-side first angle panels 311, 311 that (a) are arranged across two vertically stacked large disk drives 310, 310 and sustain the two drives from their respective sides, and (b) affixed to top face of a bay-fixing panel 221 that is affixed to an outer frame that forms bottom plane of the case 200,

(2) a plurality pairs of (in FIGS. 21-23, three pairs of) left-side and right-side second angle panels (312, 312), -, (312, 312) that (a) are sequentially arranged across adjacent two (310, 310) of a plurality of (in FIGS. 21-23, two) vertically stacked large disk drives 310, 310 that are placed on the aforementioned upper large hard disk drive (310), and (b) sustain the two adjacent drives from their respective sides, and

(3) left-side and right-side third angle panels 322 and 321 that (a) sustain a small disk drive 330 that is stacked atop the uppermost large disk drive 310 from its respective sides, and (b) are affixed respectively to the left-side and right-side second angle panels 312, 312 that are arranged at the uppermost large disk drive (310),

and wherein

(4) a plurality of second angle panels (312, 312), -, (312, 312) that have the same shape as the aforementioned second angle panels, can be installed consecutively (1) by being arranged across vertically adjacent two ((322, 322) and (321, 321)) of a plurality of third left-side and right-side third angle panels (322, 321)-(322, 321) that have the same shape as the aforementioned third angle panels, and that sustain one by one a plurality of (In FIGS. 21-23, five) small disk drives 320, 320, -, 320 that are stacked successively on the aforementioned small disk drive from their respective sides, and (2) by fixing the two adjacent third angle panels

(5) a plurality of the large and small disk drives 310, 330, 320 are stacked, through (a) the pair of the left-side and right-side first panels 311, 311, (b) the plurality pairs of the second, left-side and right-side panels (312, 312), -, (312, 312), and (c) the left-side and right-side third angle panels (322, 321), -, (322, 321), being affixed to the panels by using screws, so that the case is easy to disassemble. Therefore, a user can freely and enjoyably select a case for computer design such that additional components (modules) such as an additional disk drive can be easily housed in the case, thereby avoiding a messy desktop. Said first, second, and third left and right angle panels are made so as to be compact and lightweight, so that the entire case for computer will be more compact and lightweight than traditional cases are (details regarding this are presented below).

FIG. 29 shows two views of the first angle panel 311 of this embodiment: (a) a perspective view from the front, and (b) a plan view from above. The first angle panel 311 is a thin panel that has an L-shaped cross section formed by flex molding. Said first angle panel 311 has (1) a fixing flange 311c that is to be affixed, by using screws, to the top surface of the bay-fixing panel 221, and (2) flat installing portions 311a, 311b that extend from the fixing flange 311c in the shape of an L, and that are to be affixed, by using screws, to the sides of and across two large disk drives 310, 310 that are stacked one upon the other.

As shown in FIG. 29(b) for instance, the fixing flange 311c is provided with three through-holes 311e, 311e, 311e, through which screws are inserted to affix the fixing flange 311c to the top surface of the bay fixing panel 221. The through-hole 311e could instead be a tapped hole.

The flat installing portions 311a, 311b are provided, respectively, with two and four (2 holes by 2 rows) long through-holes 311f, 311f, -, 311f, 311f. The two long holes 311f, 311f of the flat installing portion 311a and two lower long holes 311f, 311f of the flat installing portion 311b are holes through which screws are inserted into the sides of the lowest large disk drive 310, and two higher long holes 311f, 311f are holes through which screws are inserted into the sides of the second lowest large disk drive 310 (See FIG. 22).

The flat installing portions 311a and 311b have a plurality of holes (numerals omitted) of proper size in their center and periphery, so as to make said installing portions 311a and 311b lightweight and able to provide the disk drives with good radiation of heat.

FIG. 30 is a perspective view from the front of the second angle panel 312 of this embodiment.

The second angle panel 312 is flat and thin, and it has a plurality of holes (numerals omitted) of a proper size in line along its the center longitudinally, so as to make said second angle panel 312 lightweight and able to provide the disk drives with good radiation of heat.

The second angle panel 312 has a flat installing portion 312a that is attached, by using screws, to the sides of and across two stacked large disk drives 310, 310. The flat installing portion 312a is provided with four long through-holes (2 holes by 2 rows) 312c, 312c, 312c, 312c. Two lower long holes 312c, 312c of the flat installing portion 312a are holes through which screws are inserted into the higher tapped holes in the sides of the second lowest large disk drive 310, while the upper long holes 312c, 312c of the flat installing portion 312a are holes through which screws are inserted into the lower tapped holes in the sides of the third lowest large disk drive 310. Therefore, a plurality of pairs of the second angle panels (312, 312), -, (312, 312) allows fourth lowest or more large disk drives 310, 310, -310 to be stacked successively (See FIGS. 22 and 23).

FIG. 31 is a perspective view of a third right angle panel 321 from the front of said panel, and FIG. 32 is a perspective view of said third left angle panel 322 from the rear (inside) of said panel.

A third angle panel 321 or 322 is thin and has holes (numerals omitted) of a proper size, so as to make said third angle panel lightweight and able to provide the disk drive with good radiation of heat.

The third right angle panel 321, as shown in FIG. 31, has (1) flat installing portions 321c, 321d for affixing said panel 321 to the right side of the small disk drive 330 that is stacked above the uppermost of the large disk drive (310), and (2) fixed parts 321b, 321a, which are formed in the shape of a crank and that extend outwards to the right from said flat installing portions 321c, 321d for use in affixing, by using screws, said right angle panel 321 to the flat installing portion 312a of the second angle panel 312 that is arranged on the right side of the uppermost large disk drive (310).

Both of the flat installing portions 321c and 321d are provided with one long through-hole 321f, 321f (two long through-holes in total), which are holes through which screws are inserted into the right side tapped holes of a small disk drive 330 or 320.

Both of the fixed parts 321b, 321a are provided with two long tapped holes 321e, one below and one above the longitudinal centerline of said right angle panel 321â€”i.e., a total of four tapped holes 321e, 321e, 321e, 321e (two holes by two rows)â€”through which screws are inserted into the flat installing portions 312a, 312a of the two vertically arranged right-side second angle panels 312, 312.

Screws are inserted through the two lower tapped holes 321e, 321e of the fixed part 321b or 321a of the third right angle panel 321 and into the two upper long holes 312c, 312c of the flat installing portion 312a of the second angle panel 312 arranged on the lower right of the third right angle panel 321. On the other hand, screws are inserted through the two upper tapped holes 321e, 321e of the fixed part 321b or 321a of the third right angle panel 321 and into the two lower long holes 312c, 312c of the flat installing portion 312a of the second angle panel 312 arranged on the upper right of the third right angle panel 321.

The third left angle panel 322 is formed as shown in FIG. 32, having a symmetrical form that is a mirror image of the aforementioned third right angle panel 321 (FIG. 31).

The third left angle panel 322 has (1) flat installing portions 322c, 322d for affixing said panel 321 to the left side of the small disk drive 330 that is stacked above the uppermost of the large disk drive (310), and (2) fixed parts 322b, 322a, which are formed in the shape of a crank and that extend outwards to the left from said flat installing portions 322c, 322d for use in affixing, by using screws, said left angle panel 322 to the flat installing portion 312a of the second angle panel 312 that is arranged on the left side of the uppermost large disk drive (310).

Both of the flat installing portions 322c, 322d are provided with one long through-hole 322f, 322f (two long through-holes in total), which are holes through which screws are inserted into the left side tapped holes of a small disk drive 330 or 320.

Both of the fixed parts 322b, 322a are provided with two long tapped holes 322e, one below and one above the longitudinal centerline of said right angle panel 322â€”i.e., a total of four tapped holes 322e, 322e, 322e, 322e (two holes x two rows)â€”through which screws are inserted into the flat installing portions 312a, 312a of the two vertically arranged left-side second angle panels 312, 312.

Screws are inserted through the two lower tapped holes 322e, 322e of the fixed part 322b or 322a of the third left angle panel 322 and into the two upper long holes 312c, 312c of the flat installing portion 312a of the second angle panel 312 arranged on the lower left of the third left angle panel 322. On the other hand, screws are inserted through the two upper tapped holes 322e, 322e of the fixed part 322b or 322a of the third left angle panel 322 and into the two lower long holes 312c, 312c of the flat installing portion 312a of the second angle panel 312 arranged on the upper left of the third left angle panel 322.

Therefore, the flat installing portions 312a, 312a of the left-side and right-side second angle panels 312, 312 are affixed, by using screws, so that the left and right sides of said panels 312 align with their corresponding left and right sides (vertically) of the fixed parts (322b, 322a), (321b, 321a) of the left-side and right-side third angle panels 322 and 321.

In accordance with this, a plurality of the small disk drives 330, 320, 320, -, 320 can be successively stacked by using a plurality pairs of the left-side and right-side second angle panels (312, 312), -, (312, 312). (See FIGS. 22 and 23.)

The upper end of the flat installing portion 311b of the first angle panel 311 and the lower end of the flat installing portion 312a of the second angle panel 312 are provided with engagement parts 311d and 312d that are to contact each other in order to fix the relative positions of said angle panels 311 and 312. Further, the upper end of the flat installing portion 312a of the second angle panel 312 has an engagement part 312b that is to contact an engagement part 312d of the lower end of the flat installing portion 312a of the other second angle panel 312 in order to fix the relative positions of said two angle panels 312, which are to be arranged vertically.

The first angle panels 311, the second angle panel 312s are provided with the engagement parts 311d, 312d, 312b so as to contact each other in order to fix the relative positions of said angle panels.

Therefore, by using a pair of the left-side and right-side first angle panels 311, 311, a plurality of the left-side and right-side second angle panels (312, 312), -, (312, 312), and the left-side and right-side third angle panels (322, 321), -, (322, 321), it is possible to arrange and to fix the positions of the large and small disk drives 310, 330, 320, and to ensure assembly without slippage between the front and rear ends of each other.

In this embodiment, the motherboard bay 340 that houses boards, including a motherboard, is affixed directly, as shown in FIG. 21, to the outer frame on the right side of the bottom of the case 200 by using a plurality of (in FIG. 21, five) board-installing angles 341, 341, -, 341 and is affixed to the frame 210a which is arranged horizontally and fixed by screws along the middle part of the outer frame on the right side of the case 200. This arrangement is different from a conventional motherboard bay and from the inner frame 21 of the first embodiment. Because the board-installing angles 341 have a compact and simple structure (as described in detail below), the case for computer of this embodiment is lightweight, small-footprint and easy to disassemble.

FIG. 33 is a perspective view of a board-installing angle of this embodiment.

The board-installing angle 341 is formed as a thin piece having three round projections. Said board-installing angle 341 is provided with two arms, the fixing parts 341a, 341a, that are affixed, by using screws, to the (right-side) outer frame of the bottom of the case 200 or to the frame 210a, and a single arm, an installing part 341b, which extends from the mid-point between the two fixing parts (arms) 341a, 341a and projects in the forward direction of the figure, and that is affixed, by using a screw, to the rear of the motherboard bay 340.

The fixing parts 341a, 341a are each provided with one through-hole 341c, 341c, and the installing part 341b also is provided with one through-hole 341d. The two through-holes 341c, 341c of the fixing parts 341a, 341a are holes for fixing the board-installing angle 341 to the angle-type rear face of the outer frame on the right side of the bottom or to the rear face of the affixing-frame 210a by using screws. While the through-hole 341d of the installing part 341b is a hole for fixing the board-installing angle 341 to the rear of the motherboard bay 340 (See FIG. 21).

The through-holes 341c, 341c, 341d can be either holes for screws or tapped holes.

In this embodiment, as shown in FIG. 21, the power module bay 350 for housing the power module is directly affixed to the rear panel 230 of the case 200 by using power angles 351 and a power panel (not shown).

This arrangement is different from a conventional power module bay and from using the frame member 102f of the first embodiment. Because the power angles 351 have a compact, lightweight and simple structure (as described in detail below), the case for computer of this embodiment can be lightweight, small-footprint and easy to disassemble.

FIG. 34 is a perspective view of the power angle of this embodiment.

The power angle 351 is formed in an approximate U shape and is made of thin panels. It is provided with a power-module space 351f that is surrounded by flat panels 351a, 351b, 351b that are formed in the shape of a U, and fixing flanges 351c, 351d, 351d, that are formed by bending the forward-side ends of the flat panels 351a, 351b, 351b outwards so that the power angle 351 can be affixed, by using screws, to the rear panel 230, which is the outer panel of the case 200. The central parts of the flat panels 351a, 351b, 351b are provided with rectangular holes (numerals omitted) so as to make said flat panels lightweight and able to provide the power module with good radiation of heat.

The fixing flanges 351c, 351d, 351d are provided with a plurality of (in FIG. 34, each three, two, two, total of seven holes) through-holes 351e, 351 e, -, 351e, through which screws are inserted for affixing these fixing flanges to the rear panel 230 (See FIG. 21). The through-holes 351e can be either holes for screws or tapped holes.

In this embodiment, a fan module bay 360 that houses a fan module containing a fan-installing panel 361 is affixed directly to the rear panel 230 of the case 200 as shown in FIG. 21. Because the fan-installing panel 361 is compact, lightweight and simple structure of flat rectangular shape (not shown), and has a plurality of openings for ventilation, differing in this respect from the arrangement for a fan module bay of a conventional personal computer, the case for computer of this embodiment can be lightweight, small-footprint and easy to disassemble.

Next, a third embodiment of the present invention is also applied to a full-tower-type computer. In this embodiment, a case for computer consists only of a single case 200a,

as shown in FIG. 24, which is a perspective view of the case for computer with outer panels partly removed.

The construction of the case 200a is the same as that of the case 200 of the second embodiment, except thatâ€”in contrast to the case 200, in which the power source of the power module 350 is horizontally affixed to the rear panel 230â€”the power source of the power module 350a of the case 200a is affixed to the rear panel 230 under the condition that the power source is rotated by 90 degree (counter-clockwise when viewed from the front). Therefore, in FIG. 24, the same components are referred to by using the same numerals as those of the case 200, and therefore a detailed explanation of the case is omitted here.

In this embodiment, the case for computer provides a user with both freedom for arranging devices as desired and ease of disassembly, because incidental devices (such as the power module, fan module, and the like) are installed by using installing members (such as the power angles and the fan-installing panel) that are affixed to the outer panel (such as the rear panel 230) of the case.

Next, a fourth embodiment of the present invention is applied to a minitower- or micro-tower-type computer, In this embodiment, a case for computer consists only of a single case, 400 as shown in FIGS. 25 through 27.

FIG. 25 is a perspective view from the front-left side of the case with the outer panels partly removed; FIG. 26 is a front view of the case; and FIG. 27 is a front perspective view of the exterior of the case. In FIGS. 25 through 27, the same components have the same shapes as those of the aforementioned embodiments and therefore are referred to by using the same numerals.

The case 400 of this embodiment houses, as shown in FIG. 25, an large external storage module such as a 5-inch disk drive 310, an internal storage module such as a 3.5-inch disk drive 330, a motherboard bay 440 that contains boards, including a motherboard, and other devices (not all of which are shown) for a PC. Moreover, a power-bay module 550 and a fan module bay 560 are housed in the case 400.

The front of the case 400 is provided with switches (such as a main switch to start the computer and a reset switch to restart the computer) and an SW-LED panel 450, on which indicator lamps such as a power indicator lamp and an access lamp are properly arranged. The rear of the case 400 is provided with a connector panel 441 on which connectors that connect with a power supply, a display, scanner, other computers, and electronic devices for communication, and other devices are arranged.

The case 400, as shown in FIGS. 25 and 27, is provided with (1) a frame member 410, and (2) a plurality of outer panels: (a) a bottom panel 420, (b) a rear panel 430, (c) left-side or right-side panel 440, (d) a front panel 460, and (e) a top panel 470â€”all of which are affixed to the outside of the frame member 410. FIG. 25 shows a case having a bottom panel 420, a rear panel 430, and a left-side panel 440 as the outer panels, and without a front panel 460, a right-side panel 440, and a top panel 470.

The frame member 410 form outline of a solid shape of the case 400 such that, when the outer panels 420, 430, 440, 440, 460, and 470 are affixed to the frame member 410, the case will be a rectangular parallelepiped as shown in FIGS. 25 and 27.

The frame member 410 is formed by a plurality of outer frames and a plurality of corner parts 211, with said outer frames and corner parts assembled together by using screws in a similar manner to that of the second and the third embodiments. In this arrangement, the frame member 410 is easily formed by using screws to directly connect a plurality of the outer frames with the corner parts, except for the inner frames of the first embodiment, resulting in easy disassembly.

As shown in FIGS. 25 and 26, in the case 400, a disk-drive bay 500, in which one large and one small disk drive 310 and 330 are stacked one upon the other, is provided with (1) left-side and right-side first angle panels 311, 311 (the same shape as in the second and third embodiments) that are affixed on the bottom (back side) of the bay-affixing panel 510 that is affixed to the top outer panel of the case 400, and that sustain the large disk drive 310 from the left and right sides, and (2) a pair of the left-side and right-side third angle panels 322, 321 (the same shape as in the second and third embodiments) that are affixed to the left-side and right-side first angle panels 311, 311, and sustain from the left and right sides the small disk drive 330 that is arranged under the large disk drive 310.

In this embodiment, the first angle panels 311, the left-side and right-side third angle panels 322 and 321 that have the same shape as in the second and third embodiments can be installed upside down.

Therefore, the large and small disk drives 310 and 330 can be stacked, and can be installed by a pair of the first angle panels 311, 311, the third left- and right-angle panels 322 and 321, and using screws, resulting in easy disassembly.

In this embodiment, the case 400 for a micro- or minitower-type computer can be formed so as to be compact and lightweight by affixing (pendently) the disk-drive bay 500â€”in which the large and small disk drives 310 and 330 are stacked by using a pair of first angle panels 310, 310 and third left-side and right-side angle panels 322 and 321â€”directly to the lower side of the module-affixing panel 510 in the upper part of the case 400. Further, the case and the related components housed in the case can be disassembled and transported, avoiding the need for a bulky package and greatly reducing the cost of transporting them.

In this embodiment, the motherboard bay 540 which houses one or more boards such as a motherboard and the like, is affixed to the outer frames 410a, 410a on the left and right sides of the bottom side of the case 400 by using a plurality of the board-installing angles 541, 541, -, 541 (in the figure, two each on the left and right sides), as shown in FIG. 25. This arrangement is different from the arrangement for a motherboard bay in a conventional personal computer and the arrangement using the inner frames of the first embodiment. Because the board-installing angle 441 has a compact and simple structure (as described in detail below), the case for computer of this embodiment can be lightweight, small-footprint, and easy to disassemble,

The board-installing angle 441 is formed as a thin piece having three round projections, identical to the board-installing angle 341 of the second embodiment (See FIG. 33) and therefore a detailed explanation is omitted here.

In this embodiment, the power-bay module 550 that houses the power module has a simple structure, as shown in FIG. 25, being affixed directly to the bottom panel 420 of the bottom of the case 400. As a result, a power-bay module of a conventional personal computer and the frame module 102f in the first embodiment and other components for installing a power-bay module are not necessary, so that additional saving of space and a lower weight can be attained, resulting in easy disassembly.

In this embodiment, the fan module bay 560 that houses the fan module has a simple structure, as shown in FIG. 25, being affixed directly, by using screws, to the rear connector panel 441 (box shape by thin plates) that is affixed to the rear panel 430 of the case 400. In this respect the arrangement of fan module bay 560 and the components thereof to be installed, differs from the fan module bay of publicly known conventional personal computers, and the case for computer thus saves additional space and promotes greater ease of disassembly.

In the second, third and fourth embodiments described above, the first and the second angle panels 311, 312, and the third left and right angle panels 322 and 321 have respectively the same shapes.

Therefore, the first, second, and third left and right angle panels can be used in common for a variety of case for computers, ranging from (1) large full-tower types in which a plurality of large and small internal/external storage modules (disk drives) are stacked, (2) middle-tower types that contain fewer disk drives than the full-tower types do, and (3) minitower types in which at least one large disk drive and one small disk drive are stacked. Accordingly, the costs of designing and manufacturing bays for internal/external storage module bays (disk drive bays) are reduced, so that a user can freely and enjoyably select whatever type and design of case is desired, facilitating the addition of expansion modules into the case. Further, the case and the bays for the internal/external storage modules can be disassembled simply by removing the screws used in assembly, thereby avoiding the need for a bulky package and greatly reducing the cost of transporting the computer.

The present invention is flexible and not limited to the above embodiments. For example, a case can have a simple arrangement such that outer panels are affixed to outside of a single frame member of a solid shape. Also, the exterior of the case can have a different form from any of the embodiments shown in the figures and the shape of the inner frames, the corner parts, the outer frames, and the outer panels can be changed correspondingly. Further, the number of tapped holes and through-holes can be changed arbitrarily, and the decorative screws can have a shape different than that shown in FIG. 16.

INDUSTRIAL APPLICABILITY

The case for computer of the present invention as described above has the excellent effects summarized below:

By selecting the components of the frame members and the outer panels (including the size, material, and finish), a user can enjoyably and freely design a case for computer, and can later modify the design as desired, thereby obtaining a case for computer that reflects his or her own unique preferences.

Because this invention makes it easy to add an additional module to the case, the additional module can easily be added as desired, which also eliminates the disorderly or even messy appearance.

Because the motherboard-bay, power module bay, fan module bay, and the like are small-footprint, lightweight and simple in style, the case for computer is compact and lightweight.

Further, the case and the devices for a PC can be easily disassembled for transporting, simply by removing screws, thereby avoiding the need for a bulky package and greatly reducing the cost of transporting the case.
