The present invention relates to a wall mounted shelving unit, and more particularly to a shelving unit with adjustable shelves and adjustable shelf brackets.
Prior to the present invention numerous shelving systems have been developed, but in many instances these systems are difficult to assemble and install due to various conditions of the wall structure to which they are attached. Accordingly, a real need exists for a wall mounted shelving unit which is simple to install under varying conditions of the wall structure to which the unit is attached.
Accordingly, one of the objects of the present invention is an adjustable wall mounted shelving unit which is easy to assemble and easy to adjust and install.
Another object of the present invention is a wall mounted shelving unit which is easily attached to a wall and conveniently adopted to various wall structures.
Still another object of the present invention is a wall mounted shelving unit which is simple in design, but readily adaptable to varying conditions.
In accordance with the present invention, a wall mounted shelving unit comprises at least a pair of shelf supporting brackets including a right-hand wall bracket and a left-hand wall bracket. Each bracket has an upright rear segment and an upright front segment with at least one horizontal crosspiece extending between and connected to the upright front and rear segments of each bracket.
In one embodiment, each crosspiece has at lest one upright portion to facilitate attachment of a wire shelf spanning the crosspieces on the shelf supporting brackets. Bracket loops on the upright rear segments of the right-hand and left-land wall brackets are provided for attachment to a wall. At least one wire shelf rests on opposing crosspieces with the upright portions of the crosspieces extending upwardly between wires on the shelf. The wire shelf has at least one horizontal wire generally parallel to a wall to which the wire shelving unit is to be attached. In one embodiment of the invention, the horizontal wire is adjacent to and engages the upright portions of the crosspieces forward of the upright portions to thereby prevent forward movement of the shelf relative to the shelf supports. In another embodiment, the horizontal wire is part of a downwardly extending shelf truss which rests within a receiving trough on opposite crosspieces of the brackets.
Preferably, a plurality of vertically spaced apart horizontal crosspieces are provided, each extending between and connected to the upright front and rear segments of each shelf supporting bracket. In one embodiment, at least one upright portion on each crosspiece engages the horizontal wire on the shelf. Preferably, the wall mounted shelving unit includes a plurality of wire shelves resting on the crosspieces, one shelf for each opposing pair of crosspieces on the shelf brackets.
In one embodiment, a second upright portion on each crosspiece is forward of the other upright portion. Each wire shelf has a second horizontal wire parallel to the first and forward of the other horizontal wire. The second horizontal wire is adjacent to and engages the second upright portions of the crosspieces rearward of those upright portions.
In another embodiment, the shelf includes at least two spaced apart downwardly extending shelf trusses parallel to each other and the wall to which the wire shelving unit is to be attached. In turn, the crosspieces each include two spaced apart troughs for receiving the trusses.
Preferably, the upright portions on the crosspieces of one embodiment each comprises an upwardly extending loop. Additionally, the rear segment of each shelf bracket includes a pair of vertically spaced part bracket loops for attachment to the wall. In one embodiment, the bracket loops on the rear segment of the right-hand wall bracket inwardly extend toward the left-hand wall bracket while the bracket loops on the rear segment of the left-hand wall bracket inwardly extend toward the right-hand bracket. In another embodiment, both brackets are identical, and the bracket loops on each bracket extend to the left.
Novel features and advantages of the present invention in addition to those noted above will be become apparent to persons of ordinary skill in the art from a reading of the following detailed description in conjunction with the accompanying drawings wherein similar reference characters refer to similar parts and in which:
Referring in more particularity to the drawings,
A wire shelf 30 is supported on each opposing pair of crosspieces 20 with the back and front loops 22, 24 of the crosspieces extending upwardly between adjacent front-to-back wires 32 on the shelf. Each wire shelf includes at least two spaced apart horizontal wires including a rear horizontal wire 34 and a front horizontal wire 36, both wires being generally parallel to the wall structure to which the wire shelving unit 10 is to be attached. The rear horizontal wire 34 is adjacent to and engages the back loop 22 of each crosspiece 20, and the back loop is positioned in front of the rear horizontal wire which prevents forward movement of the wire shelf 30 relative to the shelf supporting brackets 12, 14. Additionally, the front horizontal wire 36 is adjacent to and engages the front loop 24 on each crosspiece 20, and the front loop 24 is positioned behind the front horizontal wire 36. The wire shelf 30 may include additional horizontal wires such as the middle horizontal wire 38.
With the back loop 22 of each crosspiece 20 positioned in front of the rear horizontal wire 34 and the front loop 24 of each crosspiece 20 positioned behind the front horizontal wire 36, the wire shelving is locked in place on the crosspieces 20 of the shelf supporting brackets 12, 14. Such positioning prevents both forward and rearward movement of each wire shelf relative to the shelf supporting brackets.
As shown in
Both the shelf supporting brackets 12, 14 and the wire shelf 30 are fabricated from metal wire by techniques known in the art which includes spot welding of the wires where they contact one another. Normally each wire shelf includes a rear upturned portion 46 and a front downturned portion 48, as shown in
As shown best in
A wire shelf 118 is supported on each opposing pair of crosspieces 110, and in this regard the wire shelf includes a pair of spaced apart downward extending shelf supporting trusses 120, 122. The trusses are parallel to the wall to which the shelving unit 100 is to be attached, and the spacing between them is the same as spacing between the troughs 112, 114 on the crosspiece 110. The shelf supporting trusses 120, 122 are received within the troughs 112, 114 for supporting the shelf 118 in place and preventing it from movement in a forward or rearward direction relative to the crosspiece.
Each crosspiece 110 also includes an upwardly bent portion 124 which extends upwardly between the parallel wires 126 of shelf 118 to thereby prevent movement of the shelf to the left or right relative to the crosspiece.
Each shelf 118 may further include a rearward upturned portion 128 which prevents rearward movement of items placed on the shelf. Additionally, the front of the shelf 118 may include a front shelf supporting truss 130 which rests within a downturned portion 132 or trough on the crosspiece 110. As in the case of trusses 120, 122, the front truss 130 rests on the crosspiece 110 for support of the front areas of the shelf.
Both the shelf supporting brackets 102, 104 and the wire shelf 118 are fabricated from metal wire by steps known in the art which includes spot welding of the wires where they contact one another.
