Abstract
An exemplary closure assembly includes a rail assembly and a door assembly movably mounted to the rail assembly. The door assembly includes a rotary damper having a pinion, and the rail assembly includes a rack member operable to engage the pinion. As the door moves from first position to a second position, the rack member engages the pinion, thereby causing the pinion to rotate in a first rotational direction. The rotary damper resists rotation of the pinion in the first direction, thereby slowing movement of the door toward the second position. The rotary damper may be a one-way damper that does not resist rotation of the pinion in a second rotational direction such that the rotary damper does not resist movement of the door from the second position toward the first position.
