DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
(35) Set forth below is a description of what are believed to be the preferred embodiments and/or best examples of the invention claimed. Future and present alternatives and modifications to this preferred embodiment are contemplated. Any alternatives or modifications which make insubstantial changes in function, in purpose, in structure, or in result are intended to be covered by the claims of this patent.
(36) Various preferred embodiments of shelving units of the present invention are shown here in order to illustrate different aspects of the present invention, including: industrial shelving rack 10 (FIGS. 1 and 5-7); concealed post shelving rack 20 (FIGS. 2, 9A-9B, 10A-10C and 11A-11B); L shaped corner post shelving rack 30 (FIGS. 3, 12A-12B, 13A-13F and 14; and heavy-duty shelving rack 40 (FIGS. 4, 15, 16A-16B, 17-18 and 19A-19B),
(37) Referring first to industrial shelving assembly 10 of FIGS. 1 and 5-7, industrial shelving rack 10 includes, for example: four C-shaped vertical posts 11 with punched keyholes 11a located on the middle edge (FIG. 6) and running the full length of each post 11, and square punched holes 11b located at the top and bottom ends of each post 11, on each side of opposing sides of the C-shaped channel; four top and bottom cross members 12, with end flanges 12a mounting apertures 12a; four horizontal tubes 13, each of which may be welded to two adjacent vertical posts 1 as shown, and two diagonal members 15 are attached by welding to two adjacent vertical posts 11.
(38) Each adjacent pair of vertical posts 11, together with welded horizontal tubes 13 and diagonal member 15, forms a separate side frame structure 14. Each side frame structure 14 may be attached to the four top-most and bottom-most cross-members using threaded fasteners.
(39) Preferably, the threaded fasteners employed are bolts and thumb nuts with serrated edges. Bolts 50 with square necks 52 (FIG. 8A) are preferred, as they will fit into square apertures 12a on cross members 12, to prevent the bolts from rotating during assembly or use. Serrated edges 56 of thumb nuts 54 (FIGS. 8B-8C) offer enhanced manual purchase to facilitate tightening.
(40) Shelves 16 (FIG. 7) may be located at intermediate locations between the top-most and bottom-most cross-members 12. Shelves 16 may include, e.g., wire racks 17, cross members 18, and end flanges 16a mounting rivets 16a. Shelves 16 may be rapidly attached by moving rivets 16a into keyholes 11a on vertical posts 11, and pushing down on the shelving, causing the rivets 16a to move down in the keyhole from the wider portion of the keyhole to the narrower portion, wherein the shelving is fixed into position. Consumers have the choice of adding additional, adjustable-height shelves using the rivet/keyhole attachment based on individual needs and usage preferences, as keyholes are preferably located along substantially the entire length of the posts, other than the top-most and bottom-most locations of the posts (to more easily accommodate the square cutouts on cross-members 12 for connection to the posts using the threaded fasteners),
(41) It will now be understood that threaded fasteners are integral to the assembly here, as without their use as indicated, the shelving units disclosed here will collapse. However, because each side frame structure may already be integrally formed (due to the welded horizontal tubes 13 and the welded diagonal members 15), once the top-most and bottom-most cross-members 12 are attached to the posts using threaded fasteners, the shelves may be rapidly manually assembled without the use of special tools, by simply pushing shelve rivets 16a into the corresponding keyholes on vertical posts 11 (tabs and slots may alternatively be used). This hybrid connection system provides more rapid assembly than if only threaded fasteners were used, while also providing enhanced strength and durability as compared to shelving systems using only non-threaded fasteners.
(42) Referring now to FIGS. 2, 9A-9B, 10A-10C and 11A-11B, an alternative embodiment of the present invention, concealed post shelving assembly 20, is shown, and includes: four L-shaped vertical posts 22 with punched keyholes 22a located on one of the two sides of the L-shape and running the full length of each post 22, and square punched holes 22b located at the top and bottom of each post 22, and on each of the two sides of the L-shape; four top and bottom cross members 24 with square apertures 24a located at opposing ends of each cross member 24, for connection using threaded fasteners to post holes 22h; and four horizontal tubes 23, with apertures 23a, each of which connect using threaded fasteners to post holes 22b of two adjacent vertical posts 22.
(43) As shown in FIG. 2, keyholes 22 are concealed from exterior view due to the fact that the keyholes are located on the inside edges of vertical posts 22, and they are stamped only through an interior surface of the post, and not through the entire side of the post, as shown.
(44) Two adjacent vertical posts 22, and two bottom-most and top-most corresponding horizontal tubes 23, threadably fastened to the posts, form a side frame structure 25.
(45) Again, where threaded fasteners are called for above, bolts 50 with square necks 52 may be used, and may mate with thumb nuts 54 with serrated edges 56.
(46) Shelves 26 (FIG. 10C) may be located intermediate of the top-most and bottom-most cross-members 24. Shelves 26 may be pan-shaped, as shown, or alternatively employ wire racks as with shelves 16. Shelves 26 again may be rapidly attached to the posts, as shelves 26 may include rivets 26a for coupling to keyholes 22a on vertical posts 22, as shown in FIG. 10C. Shelf 26 may include floor 27 and downwardly extending sides 28, with corner cutouts 28a for accommodating post 22.
(47) Referring now to FIGS. 3, 12A-12B, 13A-13F and 14, yet another embodiment of the present invention, L-shaped corner post shelving assembly 30, is shown, and includes: four L-shaped vertical posts 32 with punched keyholes 32a running the full length of each of two L-shaped sides of each post 32, and square punched holes 32b located at the top and bottom of each of the two L-shaped sides of post 32; four top and bottom cross members 34 with square apertures 34a located at opposing ends of each cross member 34; and four horizontal tubes 33 with end apertures 33a for connection using threaded fasteners to apertures 32a on one side of L-shaped post 32.
(48) Again, where threaded fasteners are called for above, and referring to FIGS. 11A and 11B, bolts 50 with square necks 52 may be used, and mated with thumb nuts 54 with serrated edges 56.
(49) Shelves 36 may again be located intermediate of the top-most and bottom-most cross-members 34. Shelves 36 may be rapidly attached to posts 32 using the rivet/keyhole connection, or a slot/tab connection. Shelf 36 may include floor 37 and downwardly extending sides 38, with corner spaces 38a for accommodating post 32.
(50) With this example, and for the shelving rack examples that utilize an L-shaped vertical post (FIGS. 2 and 3), a pin 39 may be slid into correspondingly-sized brackets 32c which may be located on the inside corner of L-shaped post 32, to hold two adjacent vertical posts in vertical position; this allows the shelving height to be increased, as desirable, Pin 39 may be of sufficient length, thickness and material selection to provide the vertical posts that it supports with sufficient strength and durability, as will be understood by those of skill in the art.
(51) Alternatively, with the FIG. 2-type shelving assembly example, a separate coupler 67 may employed, as shown in FIG. 9B, having stamped protrusions 67a on the inside surface of the coupler that frictionally engage with the inside surfaces of the adjacent vertical post ends to provide a snug fit with the post and hold the coupler in place. Near the end of each vertical post is a stop 69 engaging the end of the coupler, to hold the coupler in position.
(52) Finally, referring to FIGS. 4, 15, 16A-163, 17-18 and 19A-19B, still another embodiment of the present invention, heavy duty shelving assembly 40, is shown, and includes: four generally C-shaped vertical posts 42 with punched keyholes 42a running the full length of each post 42, with two side-by-side keyholes located on the main side 42, and square punched holes 42b located at the top and bottom of each of posts 32, on the main side 42; four top and bottom cross members 44 with square apertures 34a threadably fastened to posts 42 at opposing ends of each cross member 44; four horizontal tubes 43, each tube 43 welded at an end to a vertical post 42 as shown; and four diagonal members 45, each welded to an inside edge of post 42 as shown.
(53) An adjacent pair of vertical posts 42, together with top-most and bottom-most welded horizontal tubes 43, and a pair of welded diagonal tubes 45, form a sturdy side frame structure 46. Each side frame structure may be connected via threaded fasteners to a pair of top-most, and a pair of bottom-most, cross members 44.
(54) Again, where threaded fasteners are employed, bolts 50 with square necks 52, mating with thumb nuts 54 with serrated edges 56, may be used.
(55) Referring now to FIGS. 17-18, with the heavy-duty shelving rack 40, for example, intermediate horizontal tubes 43 (i.e., tubes 43 other than the top-most and bottom-most tubes 43) may be connected to vertical posts 42 using thumbscrew 70 with serrated edges 71, which mates with inverted flange nut 72 having hexagon-shaped neck 73. For this purpose, the bottom of posts 42 may include internal extending flange 42c with aperture 42c, for accepting thumbscrew 70, Referring now to FIGS. 19A-19B, heavy duty shelving racks 40 may be located side-by-side, as shown. For this purpose, large U-shaped connector 80 may be inserted into adjacent apertures/cutouts 42d located at the upper ends of posts 42, to retain racks 40 together when placed side-by-side.
(56) Referring now to FIG. 20 and to U.S. Pat. No. 10,806,257, the dropped pin connection shown there (see joint pin 23 shown in FIG. 4 of the '257 patent, and described at 4:30-41) may also be preferably employed in the two shelving rack examples shown in FIGS. 1 and 4. Thus, referring to FIG. 20, dropped pin 68 may be used to connect cross members 12/44 to horizontal tubes 13/43, respectively. Wire shelving 17 may be attached as shown. Flange F on cross-member 12/441 may be attached to post P as shown.
(57) Referring to FIGS. 21-22, to further differentiate the shelving assemblies, vertical posts P carry keyholes with different shapes which may be used, such as keyholes KHa with a curved top portion and keyholes KHb with a flat top portion. With either keyhole, similar-shaped rivets may be used for engagement.
(58) The above description is not intended to limit the meaning of the words used in the following claims that define the invention. Persons of ordinary skill in the art will understand that a variety of other designs still falling within the scope of the following claims may be envisioned and used. It is contemplated that these additional examples, as well as future modifications in structure, function, or result to that disclosed here, will exist that are not substantial changes to what is claimed here, and that all such insubstantial changes in what is claimed are intended to be covered by the claims.
