Description

FIELD OF THE INVENTION

The present invention is directed generally to furniture, and more particularly to cabinets with sliding drawers and trays.

BACKGROUND OF THE INVENTION

Many cabinets, particularly those found in kitchens, include drawers for storing various items. Often, drawers are mounted to the cabinet with elongate drawer slides that are fixed to the drawer. Each drawer slide has a slide member fixed to the drawer that slidably engages a stationary member that is fixed to the walls of the cabinet (often either the slide member or the stationary member includes a small wheel that facilitates sliding motion). Some of such cabinets include multiple drawers, which can be disposed in vertically stacked fashion, side-by-side fashion, or both.

Some drawers have slides that are mounted on the underside of the drawer (so-called “undermounted” drawer slides). These drawer slides may be preferred in some environments because they are less exposed than side-mounted drawer slides (and therefore may be less exposed to damage) and may avoid taking up space on either side of the drawer. In some embodiments, undermounted slides may have mechanisms that cause the drawer to close automatically without slamming. An exemplary undermounted drawer slide is the DYNAMIC NT slide, available from Mepla-Alfit, Reinheim, Germany; another is illustrated in U.S. Pat. No. 6,854,817 to Simon.

An undermounted drawer slide may be mounted to a side wall of the cabinet, or may be mounted at either end to the front or rear wall. If the slide is to be mounted to the front or rear wall, often the wall will include mounting holes for receiving screws or other fasteners inserted through a mounting bracket that connects to the slide. However, the tolerances of cabinets and drawer slides are typically insufficiently precise to consistently position the holes in the mounting bracket for easy mounting of the drawer slide. Also, some currently popular cabinets have drawers that are configured such that, when the drawer is closed, the front face of the drawer is substantially flush with the front face of the cabinet. In such instances, it is typically desirable that the drawer be mounted precisely to ensure the flush relationship of the drawer face and cabinet face. However, achieving a flush relationship may be difficult due to inconsistencies in the thickness of the drawer face, the length of the cabinet and drawer slides, and the thickness of the front wall of the cabinet. In view of the foregoing, it may be desirable to provide a mounting technique that addresses these difficulties.

Well-known functions or constructions may not be described in detail for brevity and/or clarity.

Referring now to the drawings, a drawer slide bracket, designated broadly at 10, is shown in FIG. 1. The bracket 10 includes a main panel 12 that is generally trapezoidal in shape. Two screw holes 14a, 14b are located in the main panel 12 at approximately the same height. A split boss 16a extends horizontally from the upper edge of the main panel 12, and a second split boss 16b extends horizontally from the main panel 12 below the screw holes 14a, 14b; the split bosses 16a, 16b are vertically aligned. Ribs 18, 20 extend on the side edges of the main panel 12.

Horizontal lower guides 22, 24 extend from the lower edge of the main panel 12. Ribs 23 support the guide 22 from underneath, and ribs 25 support the guide 24 from underneath. Horizontal upper guides 26, 28 are located above the lower guides and form a horizontal gap 30. Gussets 27, 29 support the inward edges of the upper guides 26, 28. cantilevered latch 32 having a hook 34 extends generally coplanar with the lower guides 22, 24, with the and includes a hook 34 extending into the gap 30.

The bracket 10 is typically formed of a thermoplastic, such as ABS or polystyrene, and may be injection-molded. If so, hole 36 in the main panel just above the latch 32 can facilitate simplified molding of the bracket 10, as can hole 38 above the split boss 16b.

Referring now to FIGS. 2 and 3, the bracket 10 can be employed to mount a conventional drawer slide, designated broadly at 50, within a cabinet 60. The bracket 10 can be mounted to the rear wall 64 of the cabinet 60, either via screws (not shown) inserted into the holes 14a, 14b in the main panel 12, or via the insertion of the split bosses 16a, 16b into pre-formed holes in the rear wall 64. The drawer slide 50 is then mounted onto the bracket 10 via a stationary member 54; at its rear end, the stationary member 54 has a window 56 that receives the hook 34 of the latch 32. Notably, the window 56 is wider than the hook 34 of the latch 32. The edges of the stationary member 54 are received in the gap 30 in the bracket 10, wherein the gap 30 is typically sized to provide a slight snug or interference fit with the stationary member 54. The forward end of the stationary member 54 is mounted to the front wall 62 of the cabinet 60. A slide member 52 of the drawer slide 50 is mounted on the stationary member 54 and can slide easily thereon.

During installation of a drawer or tray (not shown) in the cabinet 60, the drawer/tray is fixed to the slide member 52 (and to the slide member of a second drawer slide mounted on the opposite side of the cabinet 60). (Typically, the second drawer slide is mounted to the rear wall 64 of the cabinet 60 with a bracket that is the mirror image of the bracket 10). In some instances the slide members 52 are attached to the drawer/tray first, then installed on the stationary members 54; in other instances the entire drawer slide 50 may be installed prior to mounting of the drawer/tray. In either instance, once installed, the drawer/tray can slide relative to the cabinet 60 due to the sliding action of the slide members 52 relative to the stationary members 54.

The bracket 10 can facilitate mounting of the drawer slide and drawer/tray. The bracket 10 can be mounted with either the split bosses 16a, 16b, the holes 14a, 14b, or both, depending on the preference of the installer. Also, the latch 32 enables the drawer slide 50 to be mounted on the bracket 10 quickly and easily. Moreover, because the hook 34 of the latch 32 is narrower than the window 34, the drawer slide 50 can be adjusted side-to-side to fit properly within the cabinet 60. As illustrated in FIG. 3, the forward end of the stationary member 54 of the drawer slide 50 is mounted at the vertex of the lower and side edges of an opening 66 in the front wall 62 of the cabinet 60 (this is typical of a so-called “face-frame” cabinet), The tolerances of the opening 66, the drawer/tray, and the drawer slides 50 are ordinarily relatively loose, such that the positions of the side edge of the opening 66, the front and rear ends of stationary member 54, and the somewhat imprecise; thus, the ability of the stationary member 54 of the drawer slide 50 to be adjusted side-to-side can significantly ease installation of the drawer slide 50 and, in turn, installation of the drawer or tray.

Those skilled in this art will appreciate that the bracket 10 may take alternative forms. Referring now to FIG. 4, another bracket, designated broadly at 110, is illustrated therein. The bracket 110 is similar to the bracket 10 with the exception that split bosses 16a, 16b are omitted, the screw holes 114a, 114b are relocated slightly, and the holes 136, 138 in the main panel 112 take a different shape. The bracket 110 is mounted to the rear wall of a cabinet via screws inserted through the holes 114a, 114b. The stationary member of a drawer slide can be mounted to the latch 132 and in the gap 130 as described above. An alternative bracket 110′ that includes mounting dowels 114c′, 114d′ is shown in FIG. 9.

Referring now to FIG. 5, another bracket, designated broadly at 210, is shown therein. The bracket 210 has a generally pentagonal main panel 212, and has only one upper guide 226 (i.e., there is no second upper guide as in the brackets 10, 110), which extends partially over the latch 232. Thus, the gap 230 that receives the end of the stationary member of the drawer slide extends only between the lower guide 224 and the upper guide 226, with space being present above the lower guide 222. Otherwise, the bracket 210 functions similarly to the brackets 10, 110.

Referring now to FIG. 6, a universal drawer slide bracket, designated broadly at 310, is shown therein. The bracket 310 has a generally pentagonal main panel 312 and is “universal” in the sense that it can be used on either side of a cabinet (i.e., there is no need for separate “right hand” and “left hand” brackets, but instead two universal brackets may be used). As such, the bracket 310 has mirror symmetry about a vertical axis V. The bracket 310 includes screw holes 314a, 314b, split bosses 316a, 316b, lower guides 322, 324, and upper guides 326, 328. A central platform 331 is present between the lower guides 322, 324. Two latches 332a, 332b are located between the central platform 331 and respective lower guides 322, 324. The upper guides 328, 326 are located so that they partially overlie their respective lower guides 322, 324 and latches 332a, 332b.

In use, the bracket 310 is mounted to the rear wall of the cabinet via either the split bosses 316a, 316b or the screw holes 314a, 314b. The stationary member of the drawer slide is then mounted to the appropriate latch 332a, 332b, with the corresponding upper guide 326, 328 providing the snug/interference fit described above. Because the bracket 310 is universal, the same bracket 310 can be employed on each side of the cabinet, which can simplify ordering/inventory for the installer.

Referring now to FIG. 7, a similar universal bracket 310′ is shown therein. The bracket 310′ is identical to the bracket 310 with the exception that the hole 336′ is positioned below (rather than above) the split boss 316a′.

Referring now to FIG. 8, another universal bracket, designated broadly at 410, is shown therein. The bracket 410 is similar to the bracket 310 with the exception that the bracket 410 includes a central upper guide 440 that is positioned above the central platform 431. As a result, the central upper guide 440 is in position to provide a snug/interference fit to the portion of the stationary member of the drawer slide that overlies the central platform 431, and can do so whether the stationary member is mounted to the latch 432a or the latch 432b.

Referring now to FIGS. 10 and 11, another universal drawer slide bracket, designated broadly at 510, is shown therein. The bracket 510 is somewhat similar to the bracket 410 shown in FIG. 8, but instead of relying on a latch to assist with the interconnection of the drawer slide to the bracket 510, the bracket 510 has an upper guide 540 and a lower guide 524 that each span the width of the bracket 510. A tongue of a drawer slide can slide between the upper and lower guides 540, 524 and is retained therein via an interference fit. A floor 550 is positioned below the lower guide 524 (supported by a number of ribs 526) and extends beyond the lower guide 524 to provide support to the drawer slide from underneath (this is shown in FIG. 12, wherein the drawer slide 50′ has a tongue 52′). The bracket 510 is mounted to the cabinet via split boss latches 516a, 516b).

The above examples are merely illustrative of the many applications of the brackets and assemblies of present invention. Although only a few embodiments of the present invention have been described herein, it should be understood that the present invention might be embodied in many other specific forms without departing from the spirit or scope of the invention. Therefore., the present examples and embodiments are to be considered as illustrative and not restrictive, and the invention may be modified within the scope of the appended claims.
