Spring clip upright connection for rack shelving

Abstract

A spring clip upright connection for rack shelving includes one upright with tabs and square cutouts and another upright with slots with metal spring clips. As the tabs of one upright are inserted into the slots of the other upright, the uprights are aligned and the spring metal clips open up. When the tabs are fully inserted, the clips latch into the cutouts of the slots of the other upright thereby engaging the upright sections together. This latching prevents one upright from being removed from the other upright while the slots and tabs maintain the appropriate alignment of the uprights.

Claims

1. An upright connection for shelving, comprising: a first upright having at least one tab extending near an end of the first upright: wherein said tab has a bend to space said tab in a plane that is generally parallel to said first upright, said tab having a first distance between a start of the bend and said end of said first upright; wherein said tab includes a rectangular cutout spaced entirely within the tab; a second upright having at least one slot located near an end of the second upright; wherein a start of said slot is spaced a second distance from said end of said second upright, said second distance being approximately the same as said first distance between said start of said bend and said end of said first upright; wherein a spring clip is attached to said slot and extends away from said end of said second upright; wherein the distance between said plane of said tab and said first upright is approximately the same distance as the thickness of said second upright; and wherein when said tab is inserted into said slot, said spring clip latches into said cutout thereby connecting and aligning the first and second uprights.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(8) As referenced in the figures, the same reference numerals may be used herein to refer to the same parameters and components or their similar modifications and alternatives. For purposes of description herein, the terms upper, lower, right, left, rear, front, vertical, horizontal, and derivatives thereof shall relate to the present disclosure as oriented in FIG. 1. However, it is to be understood that the present disclosure may assume various alternative orientations, except where expressly specified to the contrary. It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification are simply exemplary embodiments of the inventive concepts defined in the appended claims. Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise. The drawings referenced herein are schematic and associated views thereof are not necessarily drawn to scale.

(9) Referring to the embodiment illustrated in FIGS. 1-6, reference numeral 2 generally designates a shelving system. The shelving system 2 comprises a plurality of uprights 6A, 6B that are connected using a spring clip connection 9. The shelving assembly 2 also includes a plurality of horizontal shelf support members 4 and optional braces 10 that can support shelves 8. The openings 12 in the uprights 6A, 6B permit positioning of the horizontal shelving support members 4 and optional braces 10 at various heights. In this manner, the number and height of various shelves 8 can be adjusted.

(10) As shown in FIGS. 3 and 4, the optional braces 10 and horizontal shelving support members 4 can be connected to the uprights 6A, 6B with connectors 54, 56 that include portions 52, 58 that engage the openings 12 of the uprights 6A, 6B. The shelf 8 can then rest on the horizontal shelving support members 4 and/or the braces 10. Optionally, shelving 8 can also be mechanically connected to the horizontal shelving support member 4 and/or brace 10 by mechanical means, such as by fasteners, rivets, or tabs or by other mechanical coupling.

(11) As shown in FIGS. 1 and 2, multiple uprights 6A, 6B can be connected to increase the height of the rack shelving assembly 2. As illustrated in FIGS. 5 and 6, this spring clip connection 9 consists of one upright 6A containing a tab 20 with a cutout 22 that is on the end 7 of an upright member 6A. The tab 20 can have a bend 34 to space the tab 20 in a plane to account for the approximate thickness 43 of the end 5 of upright 6B. The bend 34 also creates a gap 35 that is the approximate size of the width 41 between the terminal end 11 of upright 6B and the beginning 13 of the slot 26. The tab 20 can be formed as part of the forming step used to create the upright 6A. Alternatively, the tab 20 can be formed by a secondary step and/or attached to the upright 6A via a weld or other coupling.

(12) The other upright member 6B has an end 5 that includes at least one formed slot 26 with an opening 28. The slot 26 can be formed as part of the forming process for upright 6B. Alternatively, the slot 26 can be formed in a secondary step and/or attached to the upright 6B via a weld or other coupling. Even if the slot 26 is formed as part of the initial forming process, it can be reinforced by a weld 32 joint or similar coupling. Both of the uprights 6A, 6B will be typically fashioned from a stable structural material, such as a high-strength polymer, or a metal, such as aluminum or steel.

(13) A spring clip 24 extends from the slot 26, as shown in FIGS. 5 and 6. The spring clip 24 can be integrally formed with the slot 26 or can be a separate part that is attached via a fastener 30 (as shown in FIGS. 5 and 6) or otherwise coupled to the slot 26 by a weld, adhesive, or other coupling. The spring clip 24 includes an end 25 that can engage a surface 27 of cutout 22 when the spring clip connection 9 is completed, as shown in FIG. 6. The spring clip 24 can be made from a stable structural material, such as a high-strength polymer, or a metal, such as aluminum or steel.

(14) FIGS. 5 and 6 illustrate the connection of the uprights 6A, 6B. The illustrated upright 6A has two tabs 20 with cutouts 22 prior to being connected to the upright 6B, having two formed slots 26 with openings 28 with spring clips 24. As the tabs 20 are inserted into the slots 26 through opening 28, the upright 6A is aligned and the spring clips 24 open up. When the tabs 20 are fully inserted, the spring clips 24 latch into the cutouts 22 of the tabs 20 of the upright 6A with the end 25 of the spring clip 24 being in the cutout 22 and potentially engaging end 27, as shown in FIG. 6. This latching prevents the uprights 6A, 6B from being removed from each other while the slots 26 and tabs 20 maintain the alignment of the uprights 6A, 6B.

(15) While the cutouts 22 are shown as being square and the end 25 of the spring clip 24 is shown as generally rectangular in shape, the cutouts 22 and end 25 of the spring clip 24 can have different shapes provided that the end 25 of the spring clip 24 can be received and engage cutout 22. In addition, while the illustrated embodiment shows the spring clip connection 9 being used with the uprights 6A, 6B, the spring clip connection 9 could also be used to connect different sections of the horizontal support members 4.
