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.

A rack beam latch for securing the end of a generally horizontally arranged beam to a vertical support post having a series of similar, vertically aligned, pin receiving openings formed therein, with the beam end having an end plate which overlaps some of the openings, and with pins formed on the end plate and extending into said openings for connecting the beam to, and for supporting the beam upon, the support post, and with the pin receiving openings being vertically elongated and having upper portions that are widened relative to their lower, narrowed portions and the pins being formed to loosely fit through the opening upper portions for insertion and removal therefrom, but formed to be closely fitted and held within the lower portions of the openings to prevent removal therefrom; said latch comprising: an upper, sheet-like cover member positioned upon said end plate and having an upper portion fastened to the end plate and an integral lower portion bent a short distance from and arranged parallel to the end plate to form a space therebetween, so as to have said cover member in it entirety immovable relative to the plate; a lower sheet-like spring member overlapping the plate and having an upper part snugly fitted within said space and an integral lower part extending below the upper cover member, and including means for positioning the spring member to the plate; a latching protuberance provided on the lower part of the spring member and extended through a latching hole formed in the plate for extending into one of the support post pin receiving openings above a pin received in that opening, to prevent movement of that pin from the narrowed portion to the widened portion of the opening; the lower part of said spring member being manually resiliently bendable away from the portion of the plate which it overlaps for moving the latching protuberance endwise out of said post opening for allowing the pin in that post opening, as well as other pins on the plate which are fitted in adjacent openings, to be manually removed upwardly into the widened portions of their respective openings for endwise removal therefrom, but otherwise the latching protuberance restrains the pins from movement out of the narrowed portions of their openings.
