Abstract
A roller track assembly includes an outer channel member and inner channel member having rollers attached and which vertically displaces in the channel of the outer channel member in response to inflation of an inflatable air bag in the channel of the outer channel member. A top plate is quick release attached to the outer channel member by a detent arrangement and covers the outer channel member and inner channel member. The top plate has openings through which rollers rotatably secured to the inner channel member selectively protrude in response to inflation of the air bag. Sealing covers prevent debris entering top plate openings from falling into the interface regions between the inner and outer channel members.
Claims15
A track assembly for selectively supporting a load during movement of the load into position in an axial direction, the assembly comprising:
- an outer channel member having a bottom wall and oppositely disposed side walls defining a first channel extending in the axial direction;
- an inner channel member extending in the axial direction;
- an inflatable air bag disposed in the first channel for supporting the inner channel member, the inner channel member being movably disposed within the outer channel member for movement in a direction normal to the axial direction;
- a plurality of rollers attached to the inner channel member, the rollers for moving between a lowered position to a raised position normal to the axial direction in response to the inflated condition of the air bag;
- a top plate having a series of openings through which the rollers project when the air bag is inflated;
- and
- detent means for releaseably securing the top plate to the outer channel member.
