PATENTED JAN] 9 new SHEET 2 OF 2 INVENTOR. //?|///VG W SHELL SHELF SUPPORTING STRUCTURE AND JOINT THEREFOR This invention relates to joints for interconnecting various structural members, particularlyhorizontal shelf supporting frame members used in store display and storage racks and the like.
Display and storage racks frequently include shelving supported on horizontal frame members. secured to brackets which are mountable at selected elevations in slotted uprights. In some cases, the end user prefers the frame members to be welded to the brackets and in other cases prefers the frame members to be separable from the brackets.
The present invention provides interlocking joints for structural support members, such as for the interconnection of the aforementioned horizontal shelf supporting frame members with the brackets, where the joints are designed selectively to form easily weldable joints or secure joints which can be easily separated and reassembled, where desired.
The features of the inventionwill become apparent upon making reference to the specification to follow, the claims and the drawings wherein: i
FIG. 1 is a perspective view of a shelf assembly with horizontal shelf supporting frame members interlocked with horizontal brackets through joints co'nstructedin accordance with the invention; f v
FIG. 2 is an exploded perspective .viewof the interlocking portions of the horizontal frame members and bracket at one end of the shelf assembly;
FIG. 3 is a perspective view of the assembled joint interconnecting a bracket with a channel memberforming one of the horizontal frame members, where the channel member has horizontally oriented flanges;
FIG. 4 is a perspective view of the assembled joint interconnecting a bracket with a channel member forming one of the horizontal frame members, where the channel member has vertically oriented flanges;
FIG. 9 is a vertical section through FIG-.4, taken along section line 9-9 therein. I
Refer now to the drawings, which show an application of the invention to a display or storage rack structure which includes horizontally spaced uprights 2-2 having vertically spaced slots 4-4 into which may be extended the teeth 6-6 of a pair of brackets 8-8 of a shelf assembly 10. The brackets 8-8 are along the uprights 2-2 to form any desired shelving arrange- 1 ment.
Each shelf assembly 10, inaddition to the brackets 8-8, includes front and rear horizontal shelf supporting frame members 12-12 which are, most advantageously, channel members having vertically spaced flanges 12a-12a oriented horizontally and a web 12b oriented vertically and extending between the inner ends of the flanges 12a-12a. The'front' and rear channel members 12-12 extend between and are interlocked with the generally horizontally extending arms 8a-8a of the brackets The shelf assembly also includes one or 'more intermediate shelf supporting frame members 14 between the front and rear shelf supporting frame members 12-12. Each intermediate shelf supporting frame member 14 most advantageously comprises a channel member with its flanges 14a-14a extending vertically downwardly from a web 14b. A shelf 16 rests upon the uppermost flanges l2 a-l2a of the channel members 12-12 and the webs 14b of each intermediate channel member 14. A molding 17 is provided for covering the forwarding facing side front channel member 12, the molding 17 hooking over the top of the channel member 12. as shown in FIG. 1. i
As previously indicated. the present invention when applied to shelving constructionrelates to the manner in which the horizontal shelf supporting frame members 12. 14. etc. interlock with the horizontal extending bracket arms -80. To this end, each bracket arm 8a has preferably struck therefrom front and rear mounting tongues 21-21 which are designed to interlock with the adjacent ends of the front and rear channel members 12-12. Each of the tongues 21 has a base portion 21a which inclines inwardly away from the vertical plane of the bracket arm 80 and an outer portion 21b which extends in a plane parallel to and spaced from the plane of the bracket arm 8a. The. outer portion 21b of each tongue 21 has an upwardly extending hooked-shaped section 21b which is in the same plane as the rest of the outer portion 21b of the tongue 21. An upwardly opening slot ZIc'separates the hookedshaped projection 21b from the main body of the outer portion 21b of the tongue 21. The slot 210 has a width equal to or slightly greater than the thickness of the vertical web 12b of the channel member with which it interlocks as illustrated.
There is provided at each end of each channel member 12 a depending tongue 23 which extends only part way across the space between the flanges 12a-12a'. The channel member tongue 23 is sized to fit into the space between the associated bracket arm tongue 21 and make extensive facial interlocking engagement with the tongue 21. There is provided at each end of the vertical web 12b of each channel member 12 a hookreceiving opening 25 through which the hook-shaped section 21b of the bracket arm tongue 21 readilypasses. The width of each opening 25 is equal to or slightly greater than the thickness of the hooked-shaped section 21b.
Each channel member tongue 23 is positioned in interlocking engagement with the bracket arm'tongue 21 by moving the ends of the channel member flanges 12a-I2a over the side of the tongue 21 on which the hooked-shaped section 21b of the tongue 21 is located, to bring the channel member into a position 'where the hooked-shaped section 21b of the bracket arm tongue 21 projects through the web opening 25 and the channel member web 12b abuts a shoulder 26 on the tongue 21 above the hooked-shaped section 21b. Then, the channel member 12 .is allowed to drop so that the upper defining edge 25a of the web opening 25 rests upon the bottom defining wall of the slot 210 where the hooked-shaped section 21b of the tongue 21 hooks around and interlocks with the channel member 12. The channel member tongue 23 then is in facial interlocking. contact with the bracket arm tongue 21. The channel member 12 is then fully interlocked with the bracket arm tongue 21 so that the channel member 12 cannot be removed from the tongue 21 without first raising the channel member 12 and then pulling the same horizontally from the tongue 21. It is apparent that the weight of the shelf 16 and any articles carried thereby will,keep each of the channel members 12-12 solidly in place on the associated bracket arm tongues 21-21.
For mounting each end of each intermediate channel member 14 there is provided on each bracket arm 8a a mounting tongue 28 preferably struck from the bracket arm 8a. The tongue 28 has a base portion 28a inclining inwardly away from the plane of the bracket arm 8a and an outer portion 28b which extends in a plane parallel and spaced from the plane of the bracket arm 8a. The outer portion 28b of each tongue 280 has forwardly and rearwardly extending tapered projections 28b'28b'.
At each end of each intermediate channel 14 there is provided a tongue 30 which extends vertically downwardly from the outer edge ofa horizontal web 14b. The tongue 30 is sized to interlock and make extensive contact with the outer portion 28b of the tongue 28 of the bracket arm 8a. The vertical flanges 140-140 of each intermediate channel member 14 are provided at each end thereof with a tongue receiving opening 31 having a width equal to or slightly greater than the thickness of the associated bracket arm tongue 28. The distance between the outermost edges of the tapered tongue projections 28b'-28b is greater than the space between the flanges'14b-l4b so that the projections 28-28 will enter the flange openings 31-31 when the channel member 14 is positioned over the tongue 28. The end of an intermediate channel member is mounted upon the associated bracket arm tongue 28 by'tilting the channel member 14 so that one flange 14a is higher than the other, as shown in FIG. 2. Then, the lower flange is slid into a position where the tongue 30 is in interlocking facial contact with the bracket arm tongue 28 and the tapered projection 28' enters the opening 31 of the lower flange 14a. The shelf supporting member is then turned into a horizontal position by a slight rotational motion thereof which will bring the other tapered tongue projection 28b into the associated flange opening 31. i
The exposed faces of the interlocking pairs of tongues 21- 23 and 28-30 are readily accessible to the electrodes of a welding device where it is desired to' weld channel members 12 and 14 to the bracket arms 8a. However, secure and stable joints are formed between the channel members and the bracket arms 8a without such welding due to the interlocking joint construction described.
it should be understood that numerous modifications may be made in the most preferred form of the invention described above without deviating from the broader aspects thereof.
