United States Patent 04 M ce 2,909,289 g HOLD-DOWN `CLIP :ron SHELF Floyd S. Laurie, Birmingham, Mich., assignor to American Metal Products Company, Detroit, Mich., a corporation of Michigan Application July '19, 1954, Serial No. 444,209
7 Claims. (Cl. 211-1'36) This invention relates to improvements in metal shelving and particularly Vtoa hold-down clip for locking a shelf to its support. A f
The main objectsV of this invention are: tol provide a hold-down clip which lclamps the shelf to its support; to provide a hold-down clip for metal shelving which is of .angular form havinga rib section at the corner and a linger at thetop end which interlock between a shelf and upright, and in general to provide locking means for a shelf which is simple-in construction, positive in operation and economical of manufacture.
Other objects relating to details of vthe invention will appear from the description to follow of a preferred embodiment of the invention illustrated in the accompanying drawing, wherein:
Figure 1 is a broken perspective view of a shelving structure embodying the features of the present invention;
Fig. 2 is an enlarged fragmentary view of the structure illustrated in Fig. 1, showing details of the lock for the shelf;
Fig. 3 is an enlarged sectional View of the structure illustrated in Fig. 2 taken on the lines 3 3 thereof, with parts of one unit shown in full lines and an adjacent unit shown in dotted lines for illustrating certain of the steps in erecting, and
Fig. 4 is a perspective view of a shelf supporting bracket.
The embodiment of the invention illustrated in the drawing comprises four uprights or columns 1 of angular section disposed with the angles facing inwardly. The
shelves designated generally by the numeral 2 are formedl of sheet metal. Desirably the side flanges 3 of the uprights are relatively narrow as compared to the end anges 4 which are longitudinally offset or ribbed at 5. This substantially stiffens the flanges of the uprights and provides clearance for the shelving supports when sections are disposed in end to end relation as indicated by full lines and dotted lines in Fig. 3.
The offset portions of the uprights have a vertical series of rectangular apertures 6 and circular apertures 7 arranged in alternating relation.
The shelves 2 have downwardly and inwardly turned flanges 8 extending along the side edges thereof and downwardly and inwardly turned flanges 9 on their front and rear edges. As shown in Fig. 3, the anges 8 are preferably wider than the anges 9 so that the inturned portion thereof extends below the end flanges, permitting the end flanges to extend into end edge abutting relation with the inner sides of the side ilanges.
The shelves are supported from the uprights by hanger brackets designated generally by the numeral 10. These are of upwardly facing channel section having a web 19 and two side flanges 20 and 21 and of such dimension as is best shown in Figs. 3 and 4. The sides 21 of the hanger brackets have outturned anges 11 on their upper edges engageable with rectangilar apertures 6 in the uprights. One half of the liange 11 extends downwardly at 22 to form a securing hook portion, leaving the re- 2,909,289 Patented Oct. 20, 1959 mainder of the space for the half of the ange 22 extending from the opposite hanger bracket, :as illustrated .in Fig. Y3. The shelves have the downwardly and inwardly disposed edge iianges 9.placed within the brackets between the sides and 21 thereof, the sides 21 being disposed in abuttingrelation to'the uprights. The -top edge 23 of the flange 20 of the brackets 10 engages` the undersides of theshelves. All of the above structure is illustrated, described andclaimed in the copending application .of William B. Lyon, Srerial No. 436,425, filed June 14, 1954, and assigned to the'assignee of the jpresent invention. f v' i The shelves are locked in the hangers by hold-down clips or members, designated generally by the numeral 13 Which'are of :angular shape. The vert-ical portion 14 of the clip is supported against the side of the uprights i Iand its horizontal portion-15 is disposed in overlapping relation to the top surfacesof the shelves. The clip has a laterally and upwardly extending lug 17 struck from `the vertical portion 14 near the top thereof. 'The lug extends through avcircular aperture-7 `in the upright abovethe aperture 6 with which the hanger'bracket V,is engaged. r
The hold-down clip 13 is of such length that the hori- Vzontal portion 15 engagesrtheushelves, to lockit in` the ass'ociated'bracket. The clip 13 is provided with a rib or offset 16 in extension of the vertical portion 14 and below the horizontal portion 15, the offset engaging the groove-like recess 24 between the top edge of the shelf and the top of the hanger bracket. When the clip 13 is in position, the rib 16 is disposed in a recess and securely holds the clip in assembled position.
When the shelf structure is to be assembled, the brackets 10 are hooked into selected apertures 6, and a shelf 2 is placed thereon as is illustrated in Fig. 3. The lugs 17 of the clips 13 are inserted in an aperture 7 as indicated by dotted lines in Fig. 3 and forced into locking position, as shown by full lines, with the horizontal portion 15 in engagement with the top surface of the shelf. In this position the ribs 16 extend into the recesses at the shelf edges and retain the clips 13 in locking position. An aperture '18 is provided through the vertical portion 114 of the clip 13 near the bottom thereof to permit a rod to pass therethrough and through the adjacent aperture 6 to engage a clip on the opposite section and force the rib 16 from the recess so that the clip can readily be removed. It will be noted that the aperture is located at one side of the center line so that when the clips are disposed with the vertical portion in back to back relationship, the apertures 18 will be out of aligned relationship.
What is claimed is:
1. A clip for clamping a shelf to brackets secured on uprights, said clip having a vertical portion and a horizontal portion at the bottom of the vertical portion in substantially right-angular relationship, the vertical portion being extended below the horizontal portion to form a rib, and means at the upper end of the vertical portion by which it is secured to an upright.
2. A clip for clamping a shelf to brackets secured on uprights, said clip having a vertical portion and a horizontal portion at the bottom of the vertical portion in substantially right-angular relationship, the vertical portion being extended below the horizontal portion to form a rib, and a lug extending from said vertical portion on the side opposite to that from which the horizontal portion extends. v
