  • Patent number: 6030126
    Abstract: The Two Axis Track Roller is in the form of two sealed bearings mounted to a single stud which allows the device to carry loads in two dimensional axis. In this way the device can carry a load along a track as well as guide along a track wall. When used in pairs the device can be "pre-loaded" which allows for precise guiding of linear motion. The conventional bearing used provide internal balls and rollers which ride on their internal precision ground and hardened surfaces. The external bearing surfaces thus can ride on non hardened track surfaces whose precision is dictated only by the application requirements. Since the bearings are sealed the bearing balls and rollers do not come in contact with environmental contaminants so bearing life is increased.

  • Patent number: 5337676
    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.
