An optional extraction hole (20) and/or an optional extraction ridge (22) may be provided.

Description

BACKGROUND

A smooth-looking bed cover gives an impression of neatness and attention to detail. To achieve that look, the bottom sheet that covers the mattress is often a fitted sheet, meaning that it has elastic at the corners, and sometimes along the top and bottom edges and sides. When the bottom sheet is taut, the upper sheet and any additional bed covers, such as blankets and spreads, will have a smooth, unwrinkled appearance. If, however, the bottom sheet is loose it can bunch or wrinkle, and this can result in the topmost bed cover, such as a spread, having sags and wrinkles and a less than desirable appearance.

Moreover, a smooth-looking bed cover is typically desirable from the perspective of a user in terms of comfort. A bunched or wrinkled bottom sheet can be uncomfortable for a user to lay upon.

In addition, bottom sheets are made to fit various sized mattresses according to their top surface dimensions such as twin, double, queen and king. However, even though these sheets fit the top surface dimensions, the depth of mattresses varies substantially and the manufactured pockets composing the vertical sides of these “fitted” sheets must be tall enough to accommodate the maximum mattress depth or the fitted sheets will quickly rise up on the mattress and become loose fitting. Further, if the pocket is made for a thick mattress but is actually used on a less thick mattress then the fitted sheet will initially have a loose fitting. Also, the fitted sheets may become loose as they stretch during use. The result is a loose, wrinkly and wavy bottom sheet which can result in the topmost bed cover having sags and wrinkles, therefore resulting in a less than desirable appearance and feel for the user. Thus, frequent manual re-stretching and re-tucking of the fitted sheet is required in order to maintain the desired appearance.

Various devices have been proposed to assist in maintaining that tightly-fitted look. Elastic straps, installed on the underside of the mattress, attempt to maintain both initial tension on the sheet and continued tension as the sheet moves and stretches. These elastic strap systems, however, require tedious lifting and displacement of the mattress to install and reconnect the elastic straps. Rigid clips are less difficult to use than the above-mentioned elastic straps but they do not maintain tension on the sheet as it moves and stretches. There are also belt type elastic bands that encircle the vertical perimeter of the mattress. These are also difficult to install, have an unsightly appearance, and fail to maintain a smooth surface as the sheet moves and stretches.

SUMMARY

An improved bed cover retention apparatus is described.

The bed cover retention apparatus has a planar strip, an elastic band, and a clip. The planar strip has a high friction first surface, an opposing second surface, an inserted end, and a distal end. The elastic band is interposed between, and connected to, the inserted end of the planar strip and the clip. The first surface may be a lower surface, and the second surface may be a smooth upper surface.

DETAILED DESCRIPTION

FIGS. 1, 2, 3, and 4 are top, side, top perspective, and bottom perspective views, respectively, of a bed cover retention apparatus 10, showing a planar strip 12, elastic band 14, a clip 16, a band retention hole 18, a layer of a flexible material 24, an optional retraction hole 20, and an optional retraction lip or ridge 22.

FIGS. 5A to 5C are an illustration of the installation of the bed cover retention apparatus 10. The insertion end 26 of the planar strip 12 is inserted between the upper mattress 32 and the wooden base or box spring or lower mattress 30 (referred to hereinafter as the “box spring” to avoid having to repeatedly list the box spring and the lower mattress in the alternative) and the clip 16 is attached to an edge of the sheet 34, which is preferably, but not necessarily, a fitted sheet. The planar strip 12 is then pushed further between the mattress 32 and box spring 30, which causes tension to be placed on the sheet 34. The planar strip 12 is then pushed further between, or completely between, the mattress 32 and box spring 30, so that, preferably, but not necessarily, little or none of the distal, extraction end 28 is showing, thereby maximizing the tension placed on the sheet 34 and causing the sheet 34 to have a taut, smooth-looking appearance and smooth feel.

Removal is accomplished by the reverse process, pulling the planar strip 12 at least partially from between the box spring 30 and the mattress 32, and unhooking the clip 16 from the sheet 34. If another sheet 34 is to be used, then the clip 16 is attached to the sheet 34 and the planar strip 12 is then pushed back between the box spring 30 and the mattress 32. If, however, another sheet 34 is not to be immediately used, such as if the mattress 32 is to be flipped or rotated, then the planar strip 12 is pulled completely out from between the box spring 30 and the mattress 32.

FIG. 6 is another illustration of the installation of the bed cover retention apparatus 10, corresponding, from the bottom up, to FIGS. 5A-5C, respectively.

Referring again to FIGS. 1-4, the planar strip 12 preferably has a surface 12B and an opposing surface 12A. The surface 12B may covered by a flexible material 24 which provides a high friction surface, or surface 12B itself may be a high friction surface, such as a rough surface, in which case the flexible material 24 might not be used. The high friction surface provides enough friction between the planar strip 12 and the box spring 30 to prevent the tension of the elastic band 14 from pulling the planar strip 12 out from its deeply-seated position between the mattress 32 and the box spring 30. This friction is not so great however that a user cannot pull the planar strip 12 out without damaging the cover of the box spring 30. An example of a suitable material for the flexible material 24 is Product No. ALQR001A made by Riken Elastomers Corp. Other materials may also be used. In an embodiment the flexible material 24 has a rectangular pattern thereon. Other patterns may also be used provided that they provide the desired degree of friction with respect to the box spring 30.

In an implementation, the planar strip 12 is a rigid planar strip. In another implementation, the planar strip 12 is rigid enough to allow it to be pushed between the box spring 30 and the mattress 32.

In an implementation, the upper surface 12A is a smooth surface. In another implementation, the upper surface 12A provides additional friction to help hold the bed cover retention apparatus 10 in place.

In an implementation, the planar strip 12 has a length of between approximately 12 inches and 24 inches. In an implementation, the planar strip 12 has a length of between approximately 15 inches and 20 inches.

In an implementation, the planar strip 12 has a uniform width of between approximately 2 inches and 4 inches. In an implementation, the planar strip 12 has a uniform width of between approximately 3 inches and 4 inches. In another implementation, the planar strip 12 may taper so that the inserted end is smaller than the distal end.

In an implementation, the planar strip 12 has an extraction hole 20, which provides the user with a convenient way to grasp and extract the planar strip 12 that has been inserted between the mattress 32 and the box spring 30. In another implementation, the planar strip 12 does not have an extraction hole.

In an implementation, the planar strip 12 has an extraction lip or ridge 22, which provides the user with a convenient way to grasp and extract the planar strip 12 that has been inserted between the mattress 32 and the box spring 30. In another implementation, the planar strip 12 does not have an extraction lip.

In an implementation, the inserted end of the planar strip 12 is rounded or curved. In another implementation, the inserted end of the planar strip 12 is substantially squared.

In an implementation a plug fits into the retaining hole 18 and the elastic band 14 is secured to the plug. In another implementation, as seen in FIG. 7, the retaining hole 18 comprises first and second slots 18A, 18B, and the elastic band 14 is routed through the slots 18A, 18B. One end 14A of the elastic band 14 is routed through slot 18A and then through slot 18B, and the other end 14B of the elastic band 14 is also routed through slot 18A and then through slot 18B.

FIG. 8 is an illustration of an exemplary clip 16 to secure the elastic band 14. The clip 16 has a body portion 40 and an insert portion 42. The body portion 40 has a hole or aperture 44 through which the elastic band 14 is routed. The insert portion 42 has a head end 46 and a tapered end 48. In use, an edge of the sheet 34 is placed against the body portion 40 and the insert portion 42 is pushed into the body portion 40, thereby securing the sheet 34 to the clip 16. Alternatively, an edge of the sheet 34 may be routed around the tapered end 48, and then the insert portion 42 is pushed into the body portion 40, thereby securing the sheet 34 to the clip 16. For more details regarding the construction of the clip 16, please see U.S. Pat. No. 6,789,295 to Svensson, the disclosure and teachings of which are hereby incorporated herein by reference. Other types of clips may also be used but care should be taken that the clip selected does not damage the sheet 34.

FIGS. 9-11 illustrate an embodiment of the bed cover retention apparatus 10 including a retainer 50 including a protrusion 52, such as a hook, that may be affixed to the box spring 50. The retainer 50 may be affixed to the box spring 30 in one or more ways, including, but not limited to, using an adhesive, screw or nail. In this implementation, the planar strip 12 is sized and configured to be selectively, releasably secured to the retainer 50 such that, when the sheet 34 is secured to the planar strip 12, tension is applied to the sheet 34, thereby causing the sheet 34 to have a taut, smooth-looking appearance and smooth feel. It is also considered that the retainer 50 may be affixed to the bottom surface of the mattress 32 to achieve the same objective.

The disclosed bed cover retention apparatus 10 may therefore be positioned to be out of sight, provides for ease of installation, provides for ease of removal, and maintains a constant tension on the sheet as it moves and stretches during use.

Also, it will be appreciated that when a person sits or lays upon the mattress 32, the weight of that person will cause tension to be exerted on the elastic band 16. That same weight, however, presses the mattress 32 and the box spring 30 more tightly against the planar strip, thereby increasing the frictional force which prevents the planar strip 12 from being pulled outwardly.
