ABSTRACT:
A roller/damper is configured for use with an associated sliding object such as a drawer that is movable between a first position and a second position along a rail having a rack gear disposed thereon. The roller/damper includes a roller having an outside diameter that is configured for movement along the rail. A gear housing is disposed adjacent the roller and has gear teeth formed thereon for engaging the rail rack gear. A damper rotor is positioned in the gear housing. The roller, gear housing and rotor rotate about a common axis. A damping material is disposed about the damper rotor within the gear housing for damping rotation of the gear housing relative to the rotor. A shaft extends through the roller, the gear housing and the rotor. The rotor is fixed to the shaft and the roller and gear housing are rotational about the shaft independent of one another. The roller rotates as it moves along the associated rail, and when the gear housing, moving along the rail with the roller, engages the rack gear, movement of the roller/damper is dampened by the engagement of the gear housing with the rack gear.
