4 Claims. (Cl. 211---7'1) The present invention relates to racks and' similar equipment for handling and storing articles 1n organized spaced apart relation and more particularly a rack unit accessory for joining a pair of self supporting mobile simplicity of construction, relatively inexpensive manu..
facturing cost, as well as sanitary and attractive design.
These, together with other objects and advantages which will become apparent, reside in the details of construction and assembly as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, in which:
Fig. l is an expanded top perspective view, with parts broken away, showing a rack installation embodying the use of a rack unit accessory in accordance with the present invention.
Fig. 2 is an enlarged end elevation disclosing details of assembly between a sel-f supporting rack unit anda rack unit accessory as contemplated by this invention.
Fig. 3 is an enlarged fragmentary sectional view taken along line 3-3 of Fig. 2.
Fig. 4 is an enlarged sectional View taken along line 4-4 of Fig. 2.
Fig. 5 is an enlarged fragmentary section taken along line 5- 5 of Fig. 2.
A pair of mobile self supporting storage racks of identical design and construction are illustrated in the drawings in conjunction with a rack accessory unit for the purpose of presenting a specific embodiment of the present invention as applied to such pair of racks. As shown, each of said pair of racks includes a iirst inverted U-shaped tubular frame having legs and 11 joined in spaced parallel relation by an upper bridge section 12 and a second similar frame having legs 13 and 14 joined in spaced parallel relation by an upper bridge section 15. These frames are rigidly joined in spaced parallel relation at a uniform distance apart by an upper bracing member 16 having opposed parallel arms 17, a lower bracing member 13 having opposed parallel arms 19, andan intermediate bracing member 20 having opposed parallel arms 21. Thus the arms 17, 19 and 21 at one side of the members 16, 18 and 2li' provide rigid horizontal supports joining the legs 1t) and 13 while the arms 17, 19 and 21 at the opposite side of members 16, 18 and 20 provide similar supports joining the legs 11 and 14 of each of the pair of rack frames. Each of the legs 1t), 11, 13 and 14 may be provided with adjustable feet so that the racks may be levelled despite irregularities in the door. In
i i ttes Pate-nt other instances, the legs may be 1'itted with caster wheels 22 for convenience in moving the racks from placetov` place.A Horizontally extending shelf or pan supporting4 runners Z3 bridging the area between the legs-10 and 13l at selected vertically spaced apart positions are provided by means of a runner section 24 secured to and con necting the legs 1d and 13 of each rack unit frame and simi-lar runners 23 extending between the legs 11 and 14 in horizontalalignment with the runners 23 extending between legs iti and 13 are provided by means of a tion on the racks.
While accordingly functioning as storage racks, and-` with the aid of an accessory rack unit as contemplated by{ the present invention, said racks are adapted to be joined in iixed spaced relation at a selected distance apart and the area therebetween made available for similar storage of additional pans, shelves, etc. Such an accessory unit', as shown in Fig. 2, includes a series of bridging members 25, 26 and 27 of uniform size and dimension and each provided atopposite endwise portions thereof with a pair of downwardly bent hook portions 28 joined by an`v integral connecting member 28a. As shown in the drawings,l the hooks 23Y of bridging member 25 have engage-- ment with the arm 17 of upper bracing member 16 at one* side of one of the racks and with the arm 17 of the upperv bracing member 16V of other rack. Hooks 28 of bridging'4r members 26 and 27 have similar engagement with they arms 17 of the intermediate and lower bracing members 2d and 18 respectively. While thus supported in operativeposition between the racks to maintain said racks in fixed spaced apart relation, the bridging members 25, 26 and 27 provide horizontally extending load supporting shelves across the space between the racks. the connecting member 28"L is ofset in the direction of the area within the hook portions 28 joined thereby. Thus stress is. applied by the connecting member 23a against the@ surface of the arm of the bracing member opposite thereto? to yieldably resist accidental unfastening of the hook portions 28 from a position of operative engagement with said arm of the bracing member. An accessory unit forming the subject of this invention also provides means for utilizing the area between the bridging members 25, 26 and 27 for the storage of pans, shelves, etc. in the same manner that such pans, shelves, etc. are accommodated by the supporting runners 23 of the rack units. Accordingly, the accessory unit includes a pair of end members, each consisting of a pair of legs 29 and 30 connected in spaced parallel relation by supporting runners 31 arranged in parallel spaced apart relation along said legs 29 and 3i). The legs 29 and 30 are provided at their upper ends with a hook portion 32 for detachable engagement with the arms 17 of the racks on which the upper bridging member 25 is supported. The legs 29 and 30 are thus suspended from the arms 17 of the racks to position the runners 31 of each end member in horizontally paired alignment so that said runners 31 function in the same manner as the runners 23 of the rack unit. Each of the legs 29 is made up of an upper section and a lower section joined by a plate 33 to which said sections are welded. The legs 30 likewise comprise upper and lower sections joined by a similar plate 34. Similar plates 35 and 36 are secured to the lower ends of the lower section of the legs 29' and 30 respectively. When the legs 29 and 30 are in supported position on the arms 17 of the racks, the plates 33 and 34 are positioned opposite the arm 21 of the middle bracing member 2@ and the plates 35 and 36 are situated opposite the arm 19 of the lower Patented Fei.V 21, 1961u Asshown in Fig. 5,-
I agregue bracing member 18. Each of the plates 33 and 34 are joined by a bolt 38 to clamping members 37 engaging the arm 21 to establish an interlocked connection between the legs 29 and 30 and the rack on which said legs 29 and 30 are supported. The plates 35 and 36 are likewise joined by a bolt 3S to clamping member 37 engaging the arm 19 of the lower bracing member 18.
As thus assembled and operatively connected to the racks, the accessory unit forming the subject of this invention affords strong, rigid, low cost storage facilities utilizing as its end supports the sides of self supporting storage racks to which said accessory unit is connected.
, The ease with which the accessory unit of this invention can be applied to and removed from a state of operative assembly is highly advantageous in that it renders assembling and re-arranging of the storage facilities to suit a wide range of reqirements a very simple and easy matter.
Obviously the invention is not limited to the details of the illustrated accessory unit or to the details of the rack units to which it is applied since these details may be variously modified. Moreover, it is not indispensable that all the features of the invention be used conjointly since various features may be used to advantage in different combinations and sub-combinations.
