CROSS-REFERENCE TO RELATED APPLICATION

The present application is being filed concurrently with our application entitled ADJUSTABLE FACE PANEL MOUNTING ASSEMBLY, which is hereby incorporated by reference in its entirety.

BACKGROUND

1. Technical Field

The present disclosure relates to cabinet drawers, and more particularly relates to floor and fence assemblies used to support and surround removable containers.

2. Background Information

Most drawers typically consist of a bottom surrounded by four upright members defining a back wall, two side walls, and a drawer front. The contents of the drawer can be accessed through an open horizontal plane defined generally by the upper margins of the back wall and two side walls. To facilitate such access, a drawer slide can be coupled to each side of the drawer and to each side of the drawer receiving opening in the cabinet holding the drawer. Each drawer slide consists generally of a first rail that is designed to be fixed to the side of the drawer and a second rail that is designed to be fixed to the cabinet. The first and second rails are coupled to each other by inter-engaging surfaces such a glides or bearings that facilitate relative movement between the two rails. A wide variety of such drawer slides exist that are suitable for use to permit drawers to move smoothly and easily in and out of cabinetry, particularly cabinetry typically found in kitchens.

Some drawers have a different construction from that previously described. In particular, some drawers, for example drawers typically situated in under-counter cabinets that include one or more waste containers. An example is to be found in Ward et al. U.S. Pat. No. 8,091,971, the entirety of which is hereby incorporated by reference. The drawer consists of a bottom designed to support the waste containers, and may include a back wall, and side walls for maintaining the waste container in an upright position. To facilitate access, drawer slides can be coupled to an under structure supporting the drawer bottom and to the bottom of the drawer receiving opening in the cabinet holding the drawer. A soft-close mechanism can be included in the understructure supporting the drawer bottom. More recently, there has been a desire to provide such drawers that are lighter so that they can be move inward and outward with greater ease. There has also been a desire to provide such drawers that are more easily cleaned and prevent trash from falling under the drawer to ensure good hygiene in food preparation areas and other situations where such built in waste disposal drawer systems are employed.

BRIEF SUMMARY

A cabinet drawer can include a molded drawer floor having a central portion including at least one depression, each depression having a bottom wall and a sidewall having an inner surface and an outer surface. A flange can extend outwardly from an upper edge of the at least one depression. A plurality of webs can extend outward from the at least one depression outer surface for connection with a drawer slide system. A peripheral edge of the flange can include a plurality of deflectable tabs for coupling to a surrounding fence. The molded drawer floor can be injection molded or vacuum formed of polymers such as polystyrene, ABS, acrylic, polycarbonate, and polyvinylchloride.

In one embodiment, each of the plurality of deflectable tabs on the peripheral edge of the flange can include a projection directed in a first selected direction. The drawer floor can further comprise a second plurality of deflectable tabs projecting outward from the outer surface of the at least one depression. Each of the second plurality of deflectable tabs can include a projection directed in a second selected direction opposite the first selected direction. A lip can depend downwardly from the peripheral edge of the flange. A plurality of ridges can be provided on a lower surface of the flange extending between the lip and the outer surface of the at least one depression. The bottom wall of each depression can include a U-shaped trough spaced inward from the sidewall.

In one embodiment, the surrounding fence can include a skirt portion coupled to the deflectable tabs of the floor peripheral edge. The fence can also include a plurality of legs projecting upwardly from the skirt portion. A top perimeter portion of the fence can be connected to upper ends of the plurality of legs. The skirt portion can have a tubular upper margin including a step on a lower surface engaging at least one of the deflectable tabs. A planar member can extend downward from an outer surface of the tubular upper margin to hide any drawer slide mechanism coupled to the molded floor. A flange can be directed inwardly from an inner surface of the planar member that can have a step on an upper surface for engagement with the molded floor. The plurality of legs projecting upwardly from the skirt portion can have a surface shape corresponding to the tubular upper margin of the skirt portion.

In one embodiment, the legs and top portion of each side of the fence can be made by selecting a length of hollow bar stock having a total length equal to the length of the top portion and both legs. Both ends of the hollow bar stock can be cut on a diagonal and the corner portions removed. Two triangular cuts are made in such a way as to leave one wall of the hollow bar stock intact, and the two triangular portions are removed. A bending force can then be applied to the one continuous wall of the hollow bar stock at two positions outside the locations of the removal of the triangular portions, causing the hollow bar stock to bend to form the legs and top portion as a single unitary piece. The ends of the legs can then be secured to ends of a skirt portion by fasteners. Thus, each side of the fence can be quickly assembled using only two fasteners.

These and other features and advantages of the present invention will become apparent to those skilled in the art from the following description of a preferred embodiment of the present invention that is illustrated in the accompanying drawings.

FIG. 11 shows one side 22 or 24 of fence 20, both of which are preferably substantially identical to each other. Each side portion 22, 24 can include a skirt portion 26 that can be coupled to a molded floor 14. A lower edge 28 of each skirt portion 26 can be dimensioned so as to be positionable to hide or obscure the drawer slides 16. Each side portion 22, 24 can also include a pair of legs 30 projecting upwardly from the skirt portion 26. A top portion 32 of each fence side 22, 24 can be connected to the upper ends 34 of the legs 30. The lengths of legs 30 and top portion 32 can be varied based on the length of the molded floor 14 and the desired height of the fence 20. The skirt portion 26, legs 30 and top portion 32 can have a variety of shapes and can be conveniently made of aluminum or other metal by an extrusion process to have the desired configuration. In one embodiment, the skirt portion 26 can have the shape shown in FIG. 12, and the legs 30 and top portion 32 can have the shape shown in FIG. 13.

As shown in FIG. 12, the skirt portion 26 has a tubular upper portion or margin 90. A step 92 can be provided on a lower surface 94 of the upper margin 90 for engaging at least one of the deflectable tabs 58 on a molded floor 14. A planar member 96 can extend downward from an outer surface 98 of the tubular upper margin 90 to the lower edge 28. A flange 100 can be directed inwardly from an inner surface 102 of the planar member 96. A step 104 can be provided by an upper edge of the flange 100 for engaging at least one of the deflectable tabs 62 on a molded floor 14. As shown in FIG. 11, the tubular upper margin 90 can have ends 106 that are mitered to connect to the lower ends 108 of the legs 30. The tubular upper margin 90 can also include an interior web 110 adapted to receive fasteners 112 coupling the lower ends 108 of the legs 30 to the ends 106 of the skirt portion 26. As shown in FIG. 13, legs 30 and top portion 32 can be a tubular member having a curved outer wall 114 that can be identical to the curved outer wall 116 of the skirt portion 26. The legs 30 can have two planar walls 118 and 120 that can be arranged at right angles to each other. An interior web 122 can be provided that can receive fasteners 124 coupling the top portion 32 to the upper ends 126 of legs 30.

While legs 30 and top portion 32 of the sides 22, 24 of the fence 20 can be made independently of each other, a preferred method of manufacturing each side 22, 24 is shown in FIGS. 14-17. In a preferred method, a hollow bar stock 130 is selected having a total length L equal to the length of the top portion 32 and both legs 30 of one side 22 or 24. Both ends 132 of the hollow bar stock 130 are cut on a diagonal and the corner portions 134 are removed. Two triangular cuts are made in such a way as to leave the upper wall 136 of the hollow bar stock 130 intact, and the two triangular portions 138 are removed. A bending force F is then applied to the upper wall 136 of the hollow bar stock 130 at two positions outside the locations of the removal of the triangular portions 138, causing the hollow bar stock 130 to bend to form in a single unitary piece the legs 30 and top portion 32. The ends 108 of the legs 30 can then be secured to ends 106 of skirt portion 26 by fasteners 112. Thus, each side 22, 24 of the fence 20 can be quickly assembled using only two fasteners 112.

Each side 22, 24 of the fence 20 can be quickly coupled to a molded floor 14 by simply pushing the skirt portion 26 toward the flange 50 so that the peripheral edge is inserted between the lower wall 94 of the tubular upper margin 90 and the upper edge of flange 100. The pushing force on the skirt portion 26 causes the deflectable tabs 58 to engage step 92 and the deflectable tabs 62 to engage step 104. Thus each side 22, 24 of the fence 20 can be secured to the molded floor without use of any separate fasteners. Tie bars 36 can be secured to the upper ends 34 of the legs 30 at both ends of the drawer 10 to define an upper perimeter of the fence 20.

Other variations in dimension will become apparent to those skilled in the art that are still within the scope of the invention as defined in the following claims. The foregoing detailed description should be regarded as merely illustrative rather than limiting, and the following claims, including all equivalents, are intended to define the spirit and scope of this invention.
