Abstract: A shelf support structure with upright posts of sheet metal sections and horizontal braces of sheet metal sections, connecting these with each other, provides with a simple structure an inherently stable connection between the posts and the horizontal braces. The sheet metal sections of the posts have an aperture at one longitudinal side and are symmetrical in cross-section with respect to a plane crossing this aperture. The aperture is terminated on both sides by flanges protruding outwardly at right angles from the walls adjoining it and a longitudinal ledge protruding into the post is located opposite the aperture, symmetrically to the plane crossing the aperture. The horizontal braces engage with their ends into the sheet metal sections forming the posts up to the wall lying opposite the aperture and are there equipped with an indentation in whose area they embrace the longitudinal ledge in the posts in a fork-like manner.

Abstract: A latch housing of molded plastic has a flanged surface that makes surface contact around a rectangular cutout in a dimpled or recessed area of a metal panel flush with the panel surface. Four extended retainers having a lightly tapered bottom edge retain the housing in the panel. A latch having a stepwise tapered end resides within the housing with the end passing through a vertical slot in a rear wall of the housing. A spring is connected between an integral hook on the housing and the forward end of the latch to keep the latch normally in the locked position. An opening in the housing allows a finger to engage the latch and release it from the locked position.

Abstract: A device for locking a beam to an upright column. The beam is provided with hooks adapted to be inserted into holes in the upright column and to be locked by a member which is a part of a spring-activated lock device. The lock device can be extracted and moved to a position in which a first stop surface of the device rests on the outside of the beam below the hole. When the lock device is moved to a position such that a second stop surface of the lock device upon insertion of the beam into an upright moves the member to a locking position of the beam to the column.

Abstract: A T-shaped bolt for use in securing two slotted members--such as an upright post and a horizontal beam in a pallet storage rack--to each other. The tee head of the bolt is dimensioned to be inserted in a pair of aligned slots of the two members that are to be secured to each other, and then rotated so that the ends of the tee head abut edge portions of the slot in the first slotted member, with the threaded shank of the bolt extending out through the slot in the second slotted member. The nut to be threaded on the bolt is a torque resistant nut, and thus when it is first turned it will cause the bolt to rotate until its specially shaped neck abuts the edges of one or both slots. At this point, the application of a predetermined minimum torque causes the nut to be turned further upon the bolt, until it is turned up tight against the second member and secures the two slotted members to each other.

Abstract: A garment hanger bar for the trailer transportation of garments includes a tubular member having swing bars comprising rings rotatably mounted on the tubular member and an elongate rod joining the rings and spaced from the tubular member for the locking of a plurality of garment hangers thereon to prevent their removal during transportation.

Upon retraction of the release bolt, the mounting member at that end may be removed from the slot, and the hanger bar thereby released from its mounting. In another embodiment, a heavy duty support bar of rectangular cross section is provided for supporting pallets. Pairs of mounting elements are provided at each end of the support bar.

Abstract: The invention comprises a two-member bracket assembly each member cooperating with the other. A locking effect is produced on an article, such as a screw or bolt, securely mounted in a wall or the like. The first member includes a bight that is securely mounted to a frame or the like that is to hang on the wall. The bight via an aperture in it is thrust over, say, the screw-head of, the article in the wall. The second member cooperates by engaging the bight in the latter's cavity, sliding therealong and into a position on such article to lock the bracket assembly to such article. This locking effect is obtained by the second member including sections which define a slot that clips on to the article, say, behind the shoulder of the screw-head in the example above, that has been thrust through the aperture of the bight.
