Abstract
Presented is a shelf support strip fabricated from a synthetic resinous material and comprising an elongated base member configured in channel form for strength and rigidity and having integrally formed therewith a series of spaced shelf support members connected to the shelf support strip by a "live" hinge that permits pivotal retraction of the shelf support member for placement of the shelf and which permits pivotal extension of the shelf support member to provide a shelf support surface in position to support a shelf thereon.
Claims7
A shelf support strip, comprising:
- (a) an elongated base member formed from injection-molded synthetic resinous material;
- and
- (b) a series of integral injection-molded synthetic resinous material shelf support members longitudinally spaced on said base member and pivotal thereon between a retracted position and an extended shelf-support position to provide a shelf support surface perpendicular to said elongated base member when in extended shelf-support position and a force transferring portion connecting said perpendicular shelf support surface to a force transferring surface separable from said elongated base member when said shelf support members are in retracted position but abutting said base member when said shelf support member is in extended shelf-support position whereby a force imposed on said shelf support surface is transferred to said elongated base member through said force transferring portion and said force transferring surface.
A shelf support strip, comprising:
- (a) an elongated base member;
- and
- (b) a series of shelf support members longitudinally spaced on said base member and each pivotal thereon between a retracted position and an extended shelf-support position to provide a shelf support surface perpendicular to said elongated base member when in extended shelf-support position and a force transferring portion connecting said perpendicular shelf support surface to a force transferring surface separable from said elongated base member but abutting said base member when said shelf support member is in extended shelf-support position;
- (c) each said elongated base member including a generally U-shaped channel formed from synthetic resinous material and having side flanges connected integrally by a web, said web including a cluster of transversely extending reinforcing ribs each longitudinally spaced from the others and integral with said base member and defining attachment zones for said base member to a supporting structure.
