A modular roller mat for providing rolling movement of cargo units over the floor of a cargo deck. The roller mat comprises a plurality of interconnected roller tray assemblies. Each roller tray assembly comprises a tray and a plurality of modular roller assemblies including a housing and a roller unit. The tray includes a floor, a first side wall, a second side wall and a flange extending inwardly from each side wall. The housing includes a plate and a downwardly extending collar. The plate extends between the side walls of the tray and is removably attached to the flanges of the tray. The collar includes an annular sleeve through which the roller unit is inserted. The roller unit includes a rotatable retainer member. Once inserted, the roller unit retainer is rotated such that retaining lugs on the roller unit retainer engage the sleeve to retain the roller unit in the housing. The roller assemblies are easily removed and replaced in the tray and are interchangeable with one another.

Modular roller mat and roller assembly

A cargo restraint for use with a cargo carrying deck in an aircraft, the deck having an upper support surface. The restraint includes a base adapted for attachment to the deck and a guide member pivotally attached to the base. The guide member is adapted to overlie the side edge of a cargo carrying unit to vertically and laterally restrain a cargo carrying unit. The guide member also forms a vertical and lateral guide during movement of a cargo carrying unit within the aircraft. The guide member is pivotal between an upright operating position and a retracted position wherein the guide member is located below the support surface of the cargo deck and is additionally pivotal to a latched position. A spring biases the guide member from the retracted and latched positions to the upright position. A latch releasably retains the guide member in the latched position.
