Abstract
Abstract The invention provides a device for moving an object, such as an entertainment module, between a storage location within a housing location (such as the armrest of a seat) and a user location outside of the housing. The device employs a track with a central slot. A truck assembly is slideably attached to the track. The truck assembly has a load-bearing plate on one side of the track and a backing plate on the reverse side of the track. The load-bearing plate and the backing plate are held to one another by a pair of pins. Around each pin, disposed within the slot, is a bushing, preferably made of polyetheretherketone. It is also preferable that washers be disposed between the track plates and the track to assure smooth movement of the truck along the track. The device is ideally suited for moving an entertainment module, such as a video monitor, in and out of an armrest between two airline seats.
