Patent ID: 11180223

Abstract:
A roller mount for seats is used in connection with a boat and a seat. First and second base slides are mounted spaced apart on a base plate. The base slides have longitudinal rack gears. First and second top slides are mounted for linear movement on the base slides in a longitudinal direction, on a plurality of rollers. A top plate is mounted on the top slides to support the seat. First and second detent plates have longitudinal top rack gears, for selective releasable engagement with the base rack gears to preclude movement of the top slides. First and second locking bars extend longitudinally adjacent the base rack gears. The top rack gears include locking slots extending longitudinally for engagement with the locking bars, to guide the top rack gears into engagement with the base rack gears. The base rack gears and the top rack gears have teeth extending upward and inward at an angle with the base plane. The downward vector force created by the angle will eliminate backlash between the locking bar and the locking slot.
