Abstract: A locking mechanism for locking a backless wall mounted cabinet or the like to a wall panel or partition having a pair of spaced slotted standards thereon adapted to receive a plurality of equidistantly spaced linearly aligned hook-shaped tabs on the rearward edges of the cabinet side walls. The locking mechanism includes a locking tab having a pair of spaced detents thereon, which locking tab is slidable from a first position adapted to enter the slots in the slotted standard with the hook-shaped tabs to a second position which locks the hook-shaped tabs into the slotted standard. A spring-urged locking pin is constructed and arranged to retain the locking tab in its second position.

Abstract: An improved column mounted tool holder for mounting on typical basement or factory support columns of varying sizes. The tool holder includes a pair of complementay structural members that are bolted to each other about a support column to define a work surface on all sides of the column, and each structural member mounts an associated clamp member with a V-shaped clamping surface for adjusting movement to allow the clamping of different size columns. The structural members preferably are of elongated configurations with U-shaped cross sections that open sideways toward each other so as to provide upper and lower walls between which the clamp members are slidably mounted. This configuration of the structural members allows drawers to be received by the ends of the structural members to hold small parts.

Abstract: The present invention relates to a modular sign support assembly wherein duplicate units of the sign support assembly may be integrated to form a sign support structure that supports one or more signs in any number of configurations or orientations.Each sign support assembly includes a base support member that is adapted to be secured adjacent an upright pole and further includes a cantilever beam having a sign mounting frame structure secured thereto and adapted to receive and support at least one sign.
