Abstract
A device for attenuating movement of a door includes a housing having a first surface spaced apart from a second surface for defining a sliding path for an elongated sliding member. The elongated sliding member engages with at least one of the first and second surfaces when the elongated member slides in a first direction. A connecting member having a first end connected to the door and the other end to the elongated sliding member is provided so that opening of the door moves the sliding member in the first direction. Damping material is disposed between the elongated sliding member and at least one of the first and second surfaces. The damping material applies surface tension forces to the elongated sliding member when sliding in the first direction such that movement of the door attenuates or dampens the movement of the door.
