Abstract
A pallet rack system has a safety lock on end connectors of horizontal beam members to prevent accidental removal of the horizontal beams from the vertical frame supports. The safety lock includes a cross-shaped member rigidly secured to the beam connectors and a U-shaped member associated with the cross-shaped member to operatively couple the U-shaped member with the end connector. The U-shaped member includes a hook which cooperates with an aperture in the frame supports to lock the safety lock device to the frame support which, in turn, locks the horizontal beams with the vertical frame supports.
Claims8
A beam safety lock comprising:
- a cross-shaped member including four legs, one of said legs including means adapted for rigidly securing said cross-shaped member onto a stud on a beam;
- and
- a U-shaped member including a pair of legs connected by a web and a hook means extending from said web, said legs of said U-shaped member associating with said cross member for operatively coupling said V-shaped member with said cross member, said hook means adapted for cooperating with an aperture in the support for locking the beam with the support.
A beam and frame support system comprising:
- one or more beams having one or more end connectors at the beam ends, said end connectors each having one or more pins and one or more apertures;
- one or more frame supports, said one or more frame supports each having one or more apertures coupling with said one or more pins of said end connectors of said one or more beams to form a system;
- said one or more end connectors including a safety lock means comprised of:
- a cross-shaped member including four legs, one of said legs including means adapted for rigidly securing said cross-shaped member onto a stud on a beam;
- and
- a U-shaped member including a pair of legs connected by a web and a hook means extending from said web, said legs of said U-shaped member associating with said cross member for operatively coupling said U-shaped member with said cross member said hook means adapted for cooperating with an aperture in the support for locking the beam with the support.
