ADJUSTABLE RACK SHELVING 5 Sheetsiheet 3 Filed June 28, 1965 INVENTORS MILTON BLOOM RUBIN BLUM BY MORGAN, FINNEGAN. DURHAM 8x PINE ATTORNEYS United States Patent 3,346,126 ADJUSTABLE RACK SHELVING Milton Bloom, 38-29 Grant St., Fair Lawn, NJ. 07410, and Rubin Blum, 312 E. 24th St., Paterson, NJ. 07 514 Filed June 28, 1965, Ser. No. 467,527 Claims. (Cl. 211-176) This invention relates generally to adjustable shelving of utility especially in the warehouse storage of pallets carrying bulk materials and relates more particularly to certain new and useful improvements in the support connections for adjustable storage racks.
In the storage of materials, it is, of course, very desirable to utilize the maximum amount of space between the floors and ceilings of the warehouse or storage building. This has been previously recognized and many proposals have been made for providing adjustable shelving racks whereby the space between racks may be adjusted so as to accommodate various sized materials.
Heretofore, when used for the storage of pallets carrying heavy bulk materials, these prior proposals have suffered from one or more disadvantageous structural features in the supporting connections for the racks. Thus, the support connections either have not provided a quick disconnect, or have been subject to break-age under heavy loads, or have been subject to accidental disengagement during the loading of the pallets onto the rack shelves.
The support connection of the subject invention eliminates the disadvantages of the prior art by (1) providing an adjustable rack shelving in which the racks may be easily and quickly connected and disconnected to the upright frame so as to be quickly adjusted to the desired position; (2) withstanding heavy loads without shearing or otherwise failing; and (3) preventing accidental disengagement of the racks during the loading operation.
It is therefore an object of this invention to provide a novel and improved supporting connection for adjustable rack shelving which eliminates the disadvantages of the prior art.
Another object of this invention is to provide a novel and improved supporting connection for adjustable rack shelving which permits the racks to be easily and quickly connected and disconnected to the upright frame.
Another object of this invention is to provide a novel and improved supporting connection for adjustable rack shelving which prevents accidental disengagement of the rack from the upright frame.
Objects and advantages of the invention are set forth in part herein and in part will be obvious herefrom, or may be learned by practice with the invention, the same being realized and attained by means of the instrumentalities and combinations pointed out in the appended claims.
The invention consists in the novel parts, constructions, arrangements, combinations and improvements herein shown and described.
Briefly described, the present invention comprises a supporting connector for adjustable storage racks including a locking plate secured to the end of a cross supporting beam which serves as the rack shelf, a backing plate having button-headed studs mounted thereon adapted to be inserted through holes formed in an upright beam which serves as a part of the rack frame and also through keyhole slots formed in the locking plate until the stud shanks fit in the narrow portion of the keyhole slots, and safety means preventing accidental disengagement of the cross beam from the upright beam during loading of pallets onto the shelves. As here preferably embodied, this safety means comprises a spacer clip member normally riding in the bottom of the keyhole slot, which prevents the stud head from returning to the wider portion of the keyhole slot.
It will be understood that the foregoing general description and the following detailed description as well are exemplary and explanatory of the invention but are not restrictive thereof.
The accompanying drawings, referred to herein and constituting a part hereof, illustrate one embodiment of the invention, and together with the description, serve to explain the principles of the invention.
Of the drawings:
FIGURE 1 is an exploded isometric view, partly fragmentary, illustrating the order to assemblage of a safety supporting connection embodying this invention;
FIGURE 2 is a view in side elevation, partly in section and partly fragmentary, illustrating the adjustable storage rack-safety connection of FIGURE 1 in assembled relationship;
FIGURE 3 is an isometric view showing in greater detail the spacer clip member of the invention illustrated in FIGURES 1 and 2; and
FIGURE 4 is a view in front elevation, partly fragmentary, showing the safety supporting connection embodying the invention applied to a plurality of adjustable rack shelving members.
Referring now more particularly to the embodiment of the invention shown in the accompanying drawings, there is illustrated in FIGURE 1 a fragmentary portion of a cross supporting beam 10; a locking plate 12; a spacer clip member 14; a fragmentary portion of a vertical, or upright, beam 16; and a backing plate 18.
With the foregoing description in mind, the connection of a cross supporting beam to an upright beam in accordance with the invention is as follows. Studs 29 of backing plate 18 are inserted through two holes 25 on upright beam 16 at the desired level for the cross supporting beam 10 until plate 18 contacts the rear surface of the front face of beam 16. The enlarged portion 22b of keyhole slots 22 is then fitted over the button heads of studs 29 and the locking plate 12 dropped onto the stud shanks so that the shanks are positioned in the slot portions 22a of the keyholes. The diameter of the button heads being larger than that of the slot portions of the keyhole slots, the cross supporting beam is thereby connected to the upright beam.
It will be understood that the opposite end of crossbeam 10 is connected to another upright beam in a similar manner, the two rows of holes 25, 26 being sufl'iciently transversely distanced apart to accommodate two locking plates and two backing plates at the same level.
Thus there is provided a supporting connection providing a quick, easy connection for an adjustable storage rack. Also, this connection is of strong construction, capable of withstanding extremely heavy loads. It has been found that by mounting the stress receiving studs to a separate plate, as opposed, for example, to welding the studs to the upright beams, a considerably stronger resistance to shearing is achieved.
In accordance with the invention, safety means is provided for preventing accidental disengagement of the crossbeam from the upright beam. Heretofore, such disengagement frequently occurred during the loading of pallets onto the beams, usually caused by some part of the loading truck striking an upward blow to the beam, causing the locking plate to be raised, thereby exposing the button heads of the studs to the larger diametered lower portion of the keyhole slots.
As here preferably embodied, this means comprises a clip-like spacer member 14, having a solid, round head 34 mounted by a welding, or other suitable means, to one end of a flat thin plate 35. In use, plate 35 is slipped between side Zt) of locking plate 12 and the front face of beam 16, whereby head 34 normally freely rides on the bottom of keyhole slot 22. It Will be understood that plate 35 is of a length which permits it to be inserted through keyhole slot 22 after the stud head 29 has been located therein and yet hold the spacer head 34 in the slot while permitting the spacer head to move freely therewithin. As illustrated in FIGURE 2, head 34 is preferably of a thickness greater than that of side of locking plate 12 and of a sufficient diameter so that it will engage the button head of stud 29 before the latter registers with the larger diametered lower portion of the keyhole slot. It has been found that when the button head of stud 29 is slightly less than the diameter of the lower portion of keyhole slot 22, satisfactory results are achieved with a head 34 of a diameter approximately one-half the diameter of the lower portion of the keyhole slot.
It will thus be seen that with spacer 14 in place, accidental disengagement of crossbeam 10 from upright beam 16 is not possible, since the upward movement of locking plate 12 is limited to a distance insufficient for the button head of stud 29 to clear the narrow portion of the keyhole slot. Also, it will be seen that since the force of an upward blow on crossbeam 10 will be received by diametrically opposed sides of head 34, the spacer is capable of resisting heavy blows without failure.
The invention in its broader aspects is not limited to the specific embodiment herein shown and described but departures may be made therefrom within the scope of the accompanying claims, without departing from the principles of the invention and without sacrificing its chief advantages.
