Abstract: A mobile storage system includes a series of storage units that include wheel assemblies that move on floor-mounted rails. The storage units, wheel assemblies and rails are produced and shipped in disassembled, knockdown kit form, and are assembled on-site in either a lateral high density configuration or a pull-out high density configuration. The user is able to selectively configure the storage units, the wheel assemblies and the rails to provide the desired configuration of the storage system.

Abstract: A system for mounting a member such as a rail to a support surface such as a floor, made of a precast concrete material, without penetrating the floor. The rail mounting system includes a base plate secured to the upper surface of the floor via an adhesive, with one or more connectors extending upwardly from the base plate. An anchor plate is secured to the rail, and adjustment screws are interconnected with the rail for adjusting the elevation of the rail relative to the base plate. When the desired elevation of the rail is attained, engagement members such as nuts are secured to the threaded connectors extending upwardly from the base plate, to fix the height of the anchor plate, and thereby the rail. A grout layer is then applied between the base plate and the anchor plate. After the grout layer is set, the leveling screws are removed and a topping layer of concrete is applied over the components of the mounting system so as to encapsulate the base plate, the anchor plate and the engagement members.
