DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(27) An industrial rack apparatus according to a preferred embodiment of the invention is illustrated in FIGS. 1-4D and 17A-17B, and shown generally at reference numeral 10. The rack apparatus 10 comprises a plurality of shelves 20 connected to shelf beams 21 that are supported by four upright support members 11, 12, 13, 14. One pair of upright members 11, 12 is positioned at one end of the apparatus 10, and the other pair of upright members 13, 14 is positioned at the opposite end of the apparatus 10, as shown in FIG. 1.

(28) Each shelf 20 is comprised of waterfall wire decking that is connected to a pair of shelf beams 21 positioned at opposite sides of the wire decking 20. Each shelf beam 21 is attached to two opposed upright members-either upright members 11 and 13 or upright members 12 and 14.

(29) Each shelf beam 21 has a cross sectional profile shown at reference numeral 1 in FIG. 3B. A locking C channel is located approximately a the top third of the beam 21 and is shown generally at reference numeral 3 in FIG. 3B. The C channel 3 of the shelf beam 21 engages the wire decking 20 and creates a strong bond between the wire decking 20 and the shelf beam 21 while under load. The channel 3 in the beam 21 makes contact and creates a mechanical bond when the shelf is under load. As such, the thickness of the shelf beam 21, and wire decking cross support can be made of lighter material. The load applied to the shelf 20 is more evenly distributed over the entire beam 21 rather than one point specifically.

(30) As shown in FIGS. 3B and 17B, the waterfall wire decking 20 includes an additional strip of wire on the inside facilitating the mechanical connection between the beam 21 and wire decking 20. Conventional waterfall wire decking has a single wire strip applied to the outer most edge to protect the end user from potential injury. The waterfall wire decking 20 of the rack apparatus 10 includes strips of wire 2 on both sides (inside and outside). The outside strip protects the customer and the inside strip facilitates locking the wire decking 20 into the shelf beam 21.

(31) The locking C channel 3 of the shelf beam profile 1 is set back into the beam 21 so that the outer most edge of the waterfall wire decking 20 does not protrude past the large face of the shelf beam 21. The setback in the beam 21 protects the customer against injury.

(32) The overall height of the C channel 3, shown at reference numeral 4 in FIG. 3B, allows the beam 21 and wire decking 20 to flex while under load and still stay engaged into the beam 21. The shelf beam 21 and the wire decking 20 flex at different rates. As such, there must be a certain amount of clearance to allow the flexing to take place.

(33) As shown in FIG. 3B, a cross channel supports the wire decking 20. The cross channel can be attached to the shelf beam 21 using a rivet 5a, which allows the rack frame to flex to a point, and the wire decking support channels do not pop up giving the overall structure more strength. As shown in FIG. 3B, the beam 21 includes a drop-down channel 5b that allows the wire decking 20 to make contact with the shelving beam 21.

(34) As shown in FIG. 3C, a hole 5c is formed in the center of the wire decking support channel that allows a weld nut that is applied to the foldable wire decking 20 to fit into the decking 20 and keep the wire decking 20 from shifting from side to side. This is particularly helpful in preventing unwanted shifting of the wire decking 20 when large and heavy objects are slid from side to side.

(35) As shown in FIG. 4D, a hinge 6 makes contact with the wire decking 20 and prevents the grid from shifting from side to side, keeping the decking 20 square. The hinge 6 helps save space.

(36) The rack apparatus 10 can include a detachable mounting foot 30 removably attached at the base of each upright member 11, 12, 13, 14. Each foot 30 has internal bent up tabs that locate off of the upright member, and can be mounted to the floor and then have the rack applied. Preferably, the material used for the foot 30 is more than twice the thickness of each formed upright 11, 12, 13, 14.

(37) As shown in FIG. 5, extended wire formed locking tabs 25 can be inserted into the frame of the deck 20, which helps keep the deck 20 in place. According to another embodiment, the tabs 25 can be made into a loop through which a bolt can be positioned, which allows for elimination of a deck support in the event a single wire deck construction is used rather than a hinged/folding wire deck.

(38) Preferably, the rack apparatus is made of all steel construction. The rack apparatus 10 is further described in the attached appendix, which is incorporated herein.

(39) A rack apparatus according to another preferred embodiment of the invention is illustrated in FIGS. 6-13 and shown generally at reference numeral 100.

(41) As shown in FIG. 7, three square tubes 122 are positioned underneath each shelf 120 and are attached to opposed shelf beams 121 to stabilize the beams 121. A detailed view of the square tube 122 is shown in FIG. 9. One end of the square tube 122 can be preassembled to the long shelf beam 121 with bolt and nut, as shown in FIGS. 10 and 10A. When assembling, the end of the square tube that has not been preassembled to a shelf beam 121 is pulled out and attached to the opposite beam 121 with bolt and nut, as shown in FIG. 10. To facilitate insertion of the bolt through into the beam 121, a plastic channel can be inserted into a hole in the beam 121. As shown in FIG. 10A, the square tube 122 can be concealed in the beam 121 for packaging/delivery to reduce packaging size and delivery costs.

(42) The apparatus 100 includes a pair of support bars 141, 142. One end of the first support bar 141 is attached proximate the upper edge of the upright beam 112 and extends at a slant to attach proximate the lower edge of upright beam 111.
