  • Patent number: 8079313
    Abstract: A shelving system including a pair of upright members, a plurality of cross-members extending between the upright members, and a plurality of shelves. Each shelf includes a plurality of first wire members defining a support surface, as well as at least two second wire members defining a support channel. Portions of the second wire members are upturned and define first and second engagement members. During assembly, each shelf is lowered onto a cross-member until the support channel engages the cross-member, whereupon the engagement members receive a respective upright member and thereby prevent rotation of the shelf about the cross-member.

  • Patent number: 7540510
    Abstract: A movable rack for supporting articles. In a preferred embodiment, the rack comprises a frame which supports first and second shelf groups. The second shelf group can be added to the rack when additional shelf space is required and can be removed when additional shelf space is not needed or when the rack is to be moved through or stored in places with limited floor space. Wheel supports and wheels are secured with respect to the frame permitting the rack to be moved. The wheel supports are extensible outward from the frame thereby improving rack stability, particularly when one or more of the second group shelves are attached or when it is desired to move the rack.

  • Patent number: 7237754
    Abstract: An assembly for supporting a sign and adapted to engage a pole includes a pair of mounting plates disposed contiguously with a pole. Each mounting plate comprises a second aperture through which a band is inserted to connect each mounting plate to the pole. A crossmember is fed through a first aperture to support a sign or banner. The crossmember is receptive to an alignment device to prevent unwanted lateral movement. Additionally, the crossmember is receptive to two stops on either of its two ends. Each end stop prevents the sign or banner from sliding off the crossmember under adverse conditions.
