DETAILED DESCRIPTION

This Detailed Description merely describes exemplary embodiments and is not intended to limit the scope of the claims in any way. Indeed, the invention as claimed is broader than and unlimited by the described embodiments, and the terms used have their full ordinary meaning.

FIG. 1 illustrates an exploded or disassembled perspective view of an exemplary drawer slide rail 110 and mounting bracket 120 for securing the drawer slide rail to a rear wall of a furniture article (e.g., cabinet, desk), shown in phantom at A. The exemplary drawer slide rail 110 includes an elongated rail portion 111 and a tongue portion 112 bent at an approximately 90° angle from the rail portion 111. The tongue portion 112 includes a planar wall 113 defining a laterally extending slot 114, and upper and lower flanges 115, 116 bent forward from the planar wall.

The exemplary mounting bracket 120, as shown in FIGS. 2, 2 A, and 2B, includes a vertically extending (as secured to furniture article A) base wall 121 having a front surface 122 and a rear surface 123 opposite the front surface. Mounting posts 124 (e.g., threaded mounting posts to enhance grip with the mounting holes) extend from the rear surface 123 for installation in corresponding mounting holes h in the furniture article A. The mounting posts 124 may define mounting holes 124a for installing fasteners, for example, to further anchor the mounting bracket to the furniture article A. While the exemplary mounting bracket 120 includes two mounting posts 124, in other embodiments, a different number of mounting posts (e.g., one, or three or more) may be used, or a different mounting arrangement (e.g., fasteners, adhesive) may be used. In the illustrated embodiment, a rail mounting hole 125 and a bracket mounting hole 126 are provided in the base wall 121 to receive fasteners 105, 106 to further secure the mounting bracket 120 to the furniture article A.

To attach the drawer slide rail tongue portion 112 to the mounting bracket 120, the rail mounting hole 125 is alignable with the laterally extending slot 114 in the tongue portion 112. In one such exemplary arrangement, the fastener 105 may be slightly loosened to allow for lateral adjustment of the tongue portion 112 on the mounting bracket 120 to a desired lateral position, and further tightened to secure the tongue portion 112 in this desired lateral position. As shown, an end portion of the laterally extending slot 114 may be enlarged to receive the head of the fastener 105 therethrough, thus permitting installation of the tongue portion 112 onto the mounting bracket 120 without removing the fastener 105.

The exemplary mounting bracket 120 further includes opposed upper and lower hook portions 130, 140 extending from the front surface 122 of the base wall 121 and defining upper and lower slots 131, 141 for receiving the upper and lower flanges 115, 116 of the tongue portion 112 and end portions 132, 142 gripping against the planar wall 113 when the flanges are slid into the upper and lower slots. Upper and lower side walls 128, 129 extend from the front surface 122 of the base wall 121 laterally outward from the hook portions 130, 140 for engaging upper and lower surfaces of the elongated rail portion 111, for example, to further secure the elongated rail portion against vertical movement.

According to an exemplary aspect of the present disclosure, the upper and lower hook portions may include a plurality of laterally spaced upper and lower hook members to provide for independent gripping engagement by the hook members at a plurality of locations on the planar wall of the drawer slide rail tongue portion. One advantage of such an arrangement is that in the event the tongue portion is slightly bent, warped, or otherwise deformed, the hook members may independently flexible to maintain multiple engagement points with the tongue portion.

In the illustrated embodiment, the upper hook portion 130 includes first, second and third laterally spaced, downward oriented upper hook members 130a, 130b, 130c defining the upper slot 131, with end portions 132a, 132b, 132c spaced apart from the front surface 122 of the base wall 121 to define an upper gap 133 for receiving the planar wall 113 of the tongue portion 112. Likewise, the lower hook portion 140 includes first, second and third laterally spaced, downward oriented lower hook members 140a, 140b, 140c defining the lower slot 141, with end portions 142a, 142b, 142c spaced apart from the front surface 122 of the base wall 121 to define a lower gap 143 (which may be the same as the upper gap 133) for receiving the planar wall 113 of the tongue portion 112. In other embodiments, a different number of hook members may be provided (e.g., two hook members, or four or more hook members) to provide a different number of discrete engagement points with the tongue portion. The upper and lower hook portions may each include the same number of hook members (e.g., four upper hook members and four lower hook members) or a different number of hook members (e.g., four upper hook members and three lower hook members).

FIG. 3 illustrates a partial bottom cross-sectional view of the exemplary mounting bracket 120 assembled with a drawer slide rail 110′ having a deformed tongue portion 112′. As shown, the hook members 130a-c are independently flexible to maintain multiple engagement points between the hook member end portions 132a-c and the tongue portion 112′.

The hook members may be provided in a variety of shapes or configurations. In the illustrated example, as shown in the cross-sectional view of FIG. 2A, each of the plurality of upper hook members 130a-c includes a first portion 134a-c extending outward from the front surface 122 of the base wall 121, a second portion 135a-c extending downward from a forward end of the first portion 134a-c, and a third portion 136a-c extending inward (i.e., toward the front surface 122) from a lower end of the second portion 135a-c to define the end portion 132a-c of the upper hook member 130a-c. Likewise, each of the plurality of lower hook members 140a-c comprises a first portion 144a-c extending outward from the front surface 122 of the base wall 121, a second portion 145a-c extending upward from a forward end of the first portion 144a-c, and a third portion 146a-c extending inward (i.e., toward the front surface 122) from an upper end of the second portion 145a-c to define the end portion 142a-c of the lower hook member 140a-c.

As evident in FIGS. 2 and 2B, the hook members 130a-c, 140a-c may be spaced apart from each other by lateral gaps 137, 138, 147, 148 that are smaller than a lateral thickness of the hook members. In other embodiments (not shown), the hook members may be spaced apart from each other by lateral gaps that are larger than or equal to the lateral thickness of the hook members.

The end portions 132a-c, 142a-c may each be provided with a chamfered lateral end 139a-c, 149a-c proximate to an outer lateral end 150 of the mounting bracket 120, for example, to facilitate receipt of the distal end 118 of the tongue portion 112 between the hook member end portions 132a-c, 142a-c and the base wall 121 during assembly of the drawer slide rail 110 with the mounting bracket 120.

While the range of lateral limit positions may be limited only by the ends of the laterally extending slot in the tongue portion of the drawer slide rail, in other embodiments, the mounting bracket may be configured to limit lateral adjustment along a range of lateral positions between first (or outermost) and second (or innermost) lateral limit positions. In the illustrated embodiment, the outer lateral end 150 of the mounting bracket 120 includes a stop wall 127 that engages a proximal or bent end 117 of the tongue portion 112 to define a first lateral limit position of the tongue portion in a withdrawing direction (FIG. 3). According to another aspect of the present disclosure, the hook members may be positioned or otherwise configured to maintain sufficient gripping engagement of the hook members 130a-c, 140a-c against the tongue portion 112, for example, to provide sufficient rigid support for the drawer slide rail 110. As shown in FIG. 4, when the tongue portion 112 is in the outermost lateral limit position, with the bent end 117 of the tongue portion engaging the stop wall 127, the tongue portion may remain aligned with a plurality (e.g., two, or in other embodiments, more than two) of the upper and lower hook members 130a, 130b, 140a, 140b, to maintain a plurality of engagement points against the upper and lower ends of the tongue portion 112. As shown in FIG. 4, this first lateral limit position may (but need not) also coincide with abutment of the fastener 105 with the enlarged end of the tongue portion slot 114, for example, to provide additional surface abutment for the first lateral limit position.

FIG. 5 illustrates the drawer slide rail 110 assembled with the mounting bracket 120 in the innermost lateral limit position. In the exemplary embodiment, the second lateral limit position is defined by engagement of the elongated rail portion 111 with the endmost upper hook member 130a. In other embodiments, the elongated rail portion may engage the endmost lower hook member, or the endmost upper and lower hook members. In other embodiments, other limit defining portions may be provided, such as, for example, an end wall extending from the base wall front surface for engagement with a distal end of the tongue portion.

According to an exemplary aspect of the present disclosure, the bracket may be adapted to be a lightweight component that provides for rigid, robust retention of the drawer slide rail. For example, the bracket 120 may include cutouts 151, 152 adjacent to the stop wall 127 and cutouts 153, 154 adjacent to the hook portions 130, 140, as shown in FIG. 2. Additionally or alternatively, the bracket may be constructed from a lightweight yet durable material, such as, for example, ABS plastic. In some such embodiments, the bracket may have a weight that is at least about 30% less than a conventional plastic bracket for a rear mounted drawer slide rail.
