ABSTRACT:
In a frame type rack having horizontal beams whose ends are adjustably fastened to vertical posts by headed pins that extend into holes formed in the posts, a latch is provided that prevents inadvertent release of the beam pins from the holes in the post. The post holes are widened at their tops for insertion of the pins and narrowed at their bottoms to engage and prevent removal of the pins therefrom. The latch includes a plate, which is fastened to the end of the beam, and upon which three vertically aligned pins are secured for extending into corresponding holes in the post. A cover strip overlaps the plate and the upper pin which, also, rigidly secures the cover strip to the plate. A slidable spring member is held between the inner portion of the cover strip and the plate and extends beneath it. Vertical openings in the spring member receive outer end portions of the middle and lower pins. A projection of the spring member fits through an aligned hole in the plate and into the hole in the post that receives the lower pin. The projection can be moved upwardly or outwardly relative to the pin in its hole by sliding and resiliently bending the spring member so that when the projection is in the hole, it restrains its pin from moving into the widened portion of the hole from which it can be released and, conversely, when moved, frees the pin for manual movement into the widened portion of the hole for removal to disconnect the beam from the post.
