DETAILED DESCRIPTION OF THE INVENTION

Turing to the drawing, FIGS. 1 and 3 show an adjustable bed sheet retention unit 100 and FIG. 4 shows a non-adjustable bed sheet retention unit 104. Each has means for clamping a bed sheet, namely, at least two clamps 104A, which may be diametrically opposite each other on a horizontally extending grasping portion that also includes means for holding the flexible hose 116, (FIG. 2), namely, a horizontally extending ring-shaped segment 104B (FIGS. 1, 2, 4). As shown in FIG. 2, the flexible hose 116 will fit within the internal opening defined by the ring-shaped segment 104B. Preferably, the ring-shaped segment 104B has inwardly directed projections or flanges 104C that are configured to enter a spiraling groove 118 in the exterior of the flexible hose 116.

In the case of FIGS. 1 and 3, there is a vertically extending riser segment 102A (or rising portion) that has at least two pieces 102B, 102C that telescope one within the other or otherwise slide relative to each other to move through a plurality or relative positions. Indeed, the at least two pieces 102B, 102C may be retained at any desired one of the plurality of relative positions by exerting pressure to the at least two pieces 102B, 102C by extending a threaded stem 110 that extends from a wider screw head 112 to pass through aligned elongated slits or slots 105, 106 in each of the two pieces 102B, 102C to engage a nut 114 in a tightened manner so that the screw head 112 at the opposite end of the threaded screw stem and the nut press against outward facing surfaces of the two pieces 102B, 102C since both the screw head 112 and the nut 114 are wider than the slits or slots 105, 106.

Piece 102B is elongated and forms a recess 103 (FIG. 3) bordered by a rear surface 103A, two side surfaces 1038 projecting from the rear surface, and two front surfaces each projecting towards each other from respective ones of the side surfaces yet each terminating to define an opening between an edge of each of the two front surfaces. Piece 102C is dimensioned to fit within the recess 103 formed by the piece 102B and defines an elongated central slit or slot 105 in alignment with a corresponding elongated central slit or slot 106 in the piece 102B. Both slits or slots 105, 106 align with the recess 103 between the edges of the front surface of the piece 102B with the riser segment 102A in a retracted position. The threaded screw stem 110 fits through both elongated slits or slots 105, 106 with the screw head 112 being wider than the slit or slot 105, 106 and with the nut 114 being wider than the slit or slot 105, when screwed onto the threaded screw stem 110. Tightening the screw into the nut causes the screw head 112 and nut 114 to exert pressure against outward faces of respective ones of the two pieces 102B, 103C the help retain the two pieces 102B, 102C to each other.

In the case of FIG. 4, there is a vertically extending riser segment 104C (or rising portion) that rises vertically between and end of a horizontally extending base segment 104D and the ring-shaped segment 104B.

The ring-shaped segment 104 may be closed to grasp about a periphery of the hose to prevent horizontal movement of the flexible hose 116. If the ring-shaped segment 104 is corrugated on its inward facing side, the corrugations are sized to enter grooves on the exterior of the flexible hose 116 to retain the flexible hose 116 in position against relative vertical movement where the retention takes place.

The horizontally extending base segment 104D is elongated and will lie beneath a mattress and provides firm support for the performance of the retaining and holding functions. The vertically extending riser segment 104C extends along an end of the mattress at the foot of a bed. The vertically extending riser segment 104C may be height adjustable by being formed of two sliding elements that slide relative to each other vertically and secured in any relative position with respect to each other in any convention manner that two sliding pieces may be retained in their relative position with respect to each other, such as with a series of holes in one of the sliding pieces and a spring-loaded button in the other that enters into one of the series of holes when aligned and can be urged manually against spring bias to leave the hole to free the sliding pieces from their relative position.

FIG. 5 shows the bedding climate control apparatus 10 on a floor beneath a bed to blow forced air through the flexible hose 116 and out the air delivery outlet nozzle 118 to enter space between a mattress 37, which would typically have a mattress fitted mattress sheet that covers the mattress 37 (i.e., the fitted mattress sheet covers the top, both sides, both ends and a portion of the underside of the mattress by opposite ends of the mattress), and a bed sheet 43 the overlays the fitted mattress sheet. The bed is partially shown, with its mattress 37 atop a box spring 39 elevated by a frame leg 41. The flexible hose 116 extends from the fan/blower discharge in the bedding climate control apparatus to rise to the air delivery outlet nozzle 118 at the foot of the bed. The bedding retention unit 104 (see FIG. 3) has its horizontally extending base segment 104D between the mattress 37 and the box spring 39. The vertically extending riser segment 104C (or rising portion) elevates the horizontally extending ring-shaped segment 104B. The two clamps 104A are clamped to the bed sheet 43 to keep the bed sheet in place to overlay the air delivery outlet nozzle 118 and thus prevent the bed sheet from being pushed to the side off the air delivery outlet nozzle 118 by a person's feet while laying in bed. The flexible hose 116 is retained by the horizontally extending ring-shaped segment 104B.

The bedding climate control apparatus 10 and the flexible hose 116 and the air delivery outlet nozzle 118 may be constructed and operated in accordance with that of U.S. utility patent application filed in November 2014 on the same day as that of the present application and entitled â€œREMOTE SETTING AND OPERATION OF A BEDDING CLIMATE CONTROL APPARATUS WITH FORCED AIRFLOW FOR HEATING AND VENTILATING, whose contents are incorporated herein by reference, and with that of U.S. utility patent application filed in November 2014 on the same day as that of the present application and entitled â€œBEDDING CLIMATE CONTROL APPARATUS WITH FORCED AIRFLOW FOR HEATING AND VENTILATING, whose contents are incorporated herein by reference. Further, the air delivery outlet nozzle 118 may be in accordance with by U.S. design patent application Ser. No. 29/501,652 filed Sep. 5, 2014 entitled â€œAIR DELIVERY OUTLET NOZZLE:, whose contents are incorporated herein by reference. Also, the housing for the bedding climate control apparatus 10 may be in accordance with U.S. design patent application Ser. No. 29/501,656 filed Sep. 5, 2014 and entitled â€œHOUSING FOR A CLIMATE CONTROL APPARATUSâ€ , whose contents are incorporated herein by reference. In addition, the flexible hose 116 may be in accordance with U.S. design patent application Ser. No. 29/501,647 filed Sep. 5, 2014 and entitled â€œSLEEVED HOSEâ€ , whose contents are incorporated herein by reference.

FIG. 6 shows a partial view of a platform bed 45 used in place of the box spring 39 and frame leg 41 of FIG. 5. The mattress 37 rests on a base of the platform bed 45 so that the bedding retention unit 104 is positioned in a like manner except that the horizontally extending base segment 104D lies between the underside of the mattress 37 and the topside of the base of the platform bed 45. Some platform beds have a peripheral lip 46 that extends upward about the periphery of the base. The vertically extending riser segment 104C elevates the horizontally extending ring-shaped segment 104B to an elevation higher than the top of the lip 46 region of the horizontally extending ring-shaped segment 104B that meets the top of the vertically extending riser segment 104C (or rising portion) clears the lip 46.

The flexible hose 116 is a kind of air conduit. Any air conduit may be utilized in accordance with the invention as a substitute for the flexible hose 116 that is shown regardless of the shape of its diametrical cross-section be it circular, rectangular, triangular, pentagonal, hexagonal, octagonal, etc. The air conduit may be considered to terminate into an open end portion as reflected by the air delivery outlet nozzle 118.

Although the drawings show a particular shape for the air outlet delivery nozzle 118, the invention is not limited to any particular shape such as that depicted. Instead, any conventional configuration with an opening for the discharge of airflow is envisioned.

The two clamps 104A may be of any configuration suited to retain the bed sheets in position that keeps the bed sheet overlaying the air outlet delivery nozzle 18.

The horizontally extending base segment 104D is a kind of fixing portion in that it fixes the relative position of the rest of the retention unit when it is in position underneath a mattress that rests upon a surface. Such a fixing portion may be of a one piece unitary construction as shown or be in multiple elongated pieces with each as long as that depicted for the base segment 104D but not as wide yet preferably arranged to lay side by side with each other.

The vertically extending riser segment 102A or rising portion may have a configuration different from that depicted in the drawing so long as they are retractable and expandable between fully withdrawn and fully extended positions. For instance, the two pieces may telescope one into the other with each being tubular.

Since the air conduit such as the flexible hose 116 is grasped, the two clamps 104A could be attached to the air conduit itself preferably in close proximity to where the ring-shaped segment 104 grasps the air conduit. In that case, the two clamps 104A would be separate from the ring-shaped segment 104 and from the vertically extending riser segment 102A or 104B as the case may be. The two clamps 104A could be attached to a separate ring that grasps the periphery of the air conduit in a manner analogous to that of the ring-shaped segment 104.

While the foregoing description and drawings represent the preferred embodiments of the present invention, various changes and modifications may be made without departing from the scope of the present invention.
