BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a rotary reading stand that is adjustably rotated to position the sheets horizontally and vertically so that the sheets are turned horizontally and vertically based on actual requirement, made at a lower cost, and positioned precisely

2. Description of the Prior Art

A conventional reading stand is fixed without being adjusted, therefore a plurality of sheets fixed on the reading stand are turned in a single direction without being positioned horizontally and vertically to match with actual requirement.

To overcome above-mentioned shortcoming, an improved rotary reading stand is developed, but it has complicated structure that is made at a high cost.

The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide a rotary reading stand that is adjustably rotated to position the sheets horizontally and vertically so that the sheets are turned horizontally and vertically based on actual requirement, made at a lower cost, and positioned precisely.

To obtain the above objective, a rotary reading stand provided by the present invention contains:

a fixed plate;

a bottom panel fixed on the fixed plate at a predetermined angle and including a recessed area and a plurality of positioning members arranged around the recessed area, and the recessed area including a first orifice formed at a central position thereof;

a top panel including a second orifice and a number of fixing projections formed around the second orifice;

a resilient member fixed between the recessed area of the bottom panel and the top panel;

a locking unit inserting through the first and second orifices and being pushed to be in an engaging or disengaging state, wherein when the locking unit is in the engaging state, the top panel presses the resilient member so that the fixing projections retain with the positioning members, and the top panel is fixed on the bottom panel; when the locking unit is in the disengaging state, the top panel is pushed by the resilient member so that the fixing projections disengage from the positioning members to rotate the top panel relative to the bottom panel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.

Referring to FIGS. 1-3, a rotary reading stand 100 in accordance with a preferred embodiment of the present invention comprises a fixed plate 10, a bottom panel 20, a top panel 30, a resilient member 40, a locking unit 50, wherein

the fixed plate 10 includes a flat base 11 and an upward extension 12 extending upward from the base 11, the base 11 includes two holes 111 disposed thereon, and the upward extension 12 includes two bores 121 mounted thereon.

The bottom panel 20 includes a flat abutting portion 21 and a lock portion 22 extending downward from the abutting portion 21, the abutting portion 21 includes a recessed area 211 fixed on a top surface thereof, a first orifice 212 formed at a central position of the recessed area 211 and passing through the top and a bottom surfaces of the abutting portion 21, and four positioning members 213 arranged around the recessed area 211. In this embodiment, the positioning member 213 is a through aperture, and the lock portion 22 includes two openings 221, such that two fixing elements 23 are inserted through the openings 221 of the bottom panel 20 and the bores 121 of fixed plate 10 to connect the bottom panel 20 with the fixed plate 10 at a predetermined angle.

The top panel 30 includes a support portion 31, a limiting segment 32 extending toward two sides of the support portion 31, two shaft segments 33 attached on a top and a bottom ends of the support portion 31 respectively, and each shaft segment 33 includes a notch 331 disposed on an inner side thereof; the support portion 31 includes a second orifice 311 passing through a top and a bottom surfaces of the support portion 31, and the second orifice 311 is noncircular, the support portion 31 includes four fixing projections 312 formed around the second orifice 311.

The resilient member 40 is a spring and fixed between the recessed area 211 of the bottom panel 20 and the top panel 30.

The locking unit 50 includes an inserting element 51 and an adjusting element 52, the inserting element 51 is a screw bolt with a shank 511 and a disk 512, and the shank 511 includes outer threads, the adjusting element 52 is a nut with inner threads; the shank 511 of the inserting element 51 inserts through the second orifice 311, the resilient member 40, and the first orifice 212 from a top surface of the top panel 30, and the adjusting element 52 and the shank 511 are screwed together, the disk 512 of the inserting element 51 contacts with the top surface of the top panel 30 so that the top panel 30 is connected with the bottom plane 20, and the resilient member 40 is further compressed so that the fixing projections 312 of the top panel 30 engage with the positioning members 213 of the bottom panel 20.

As shown in FIG. 4, when a number of sheets 99 are fixed to the reading stand 100 horizontally, the sheets 99 are inserted to the notch 331 of the shaft segments 33 of the top panel 30, and the limiting segment 32 is used to limit a turning space of the sheets 99 so that the sheets 99 are turned horizontally.

When desiring to turn the sheets 99 vertically, the adjusting element 52 of the locking unit 50 is rotated releasably so that the locking unit 50 is released as illustrated in FIG. 5, and the top panel 30 is not compressed by the locking unit 50, hence the resilient member 40 pushes the top panel 30 to leave a predetermined distance away from the bottom panel 20 so that the fixing projections 312 of the top panel 30 disengage from the positioning members 213 of the bottom panel 20. Thereafter, the top panel 30 is rotated toward a preset angle so that the fixing projections 312 align with the positioning members 213, the adjusting element 52 is rotated tightly so that the locking unit 50 is in a tightly engaging state, and the fixing projections 312 are retained with the positioning members 213, the top panel 30 is compressed by the resilient member 40 to rotate an angle and to connect with the bottom panel 20, so that the top panel 30 is fixed horizontally as shown in FIG. 6, and the sheets 99 are turned vertically as illustrated in FIG. 7.

Besides, the fixed plate 10 is fixed on a wall 98 by ways of the holes 111 and coupling elements as shown in FIGS. 8 and 9.

Also, the positioning member 213 is capable of being formed in a recess shape.

Thereby, the reading stand is adjustably rotated to position the sheets horizontally and vertically so that the sheets are turned horizontally and vertically based on actual requirement, made at a lower cost, and positioned precisely

While we have shown and described various embodiments in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
