Abstract: A support for the lower ends of elongated articles stored in an upright position, such as the lower ends of firearms contained within a storage cabinet. The support includes a base, and one or more support members are releasably engageable with the base. Each support member receives and secures the lower end of a firearm relative to the base. Each support member is releasably engaged with the base via one or more releasable fasteners that extend through openings in the base and the support member. The base may include a series of slots, within which the fasteners are movable to adjust the position of the support members on the base. The one or more support members may be a single support member that supports the lower end of each firearm, and a series of support members are mounted along the length of the base to support the lower end of a series of articles.

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 carriage of a mobile storage system is adapted to support at least one storage unit for movement on a rail. The carriage generally includes a wheel mount structure, and a wheel mounting subassembly that includes a shaft having opposing ends, a wheel mounted to the shaft, and a first and a second mounting members that rotatably support the shaft. The wheel is located between the first and second mounting members such that the ends of the shaft extend outwardly from the first and second mounting members. The carriage further includes a cooperating mounting arrangement configured to non-rotatably mount the first and second mounting members to the wheel mount structure. The wheel extends downward from the wheel mount structure to engage the rail, and the ends of the shaft extend outward to engage a drive shaft that imparts rotation to the shaft and wheel so as to move the carriage on the rail.
