Abstract

Abstract A receptacle for motor vehicles. f.i. an ash tray, comprises a drawer movably supported with a housing between an open and a closed position, a releasable locking means for holding the drawer in its closed position and spring means for moving the drawer in its open position upon release of the locking means. In order to prevent a fast opening under the action of the springs and consequent impact on an abutment in the end position a damper means is provided between drawer and housing which retards the opening movement of the drawer.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 194 words
A receptacle, in particular for motor vehicles, comprising a housing, a drawer movably supported within the housing between a closed and an open position, a releasable locking mechanism for holding the drawer in its closed position, and spring means for moving the drawer to its open position after release of the locking mechanism, characterized in that a damping means is provided between the drawer and the housing, said damping means being constructed and arranged to oppose the spring for retarding the movement of the drawer into its open position so that a sudden impact in its open position is prevented; said damping means comprising a variable volume chamber coupled to the drawer to increase a volume of the chamber as the drawer is opened and decrease said volume as the drawer is closed; a check valve disposed between said chamber and the atmosphere, said check valve being arranged to open as said volume is decreased, said check valve having a check valve cross-sectional area; and a restricted air passage by-passing said check-valve to permit air exchange between the chamber and atmosphere and having a passage cross-sectional area smaller than the check valve cross-sectional area.
Claim 2
Dependent Claim 194 words
A receptacle, in particular for motor vehicles, comprising a housing, a drawer movably supported within the housing between a closed and an open position, a releasable locking mechanism for holding the drawer in its closed position, and spring means for moving the drawer to its open position after release of the locking mechanism, characterized in that a damping means is provided between the drawer and the housing, said damping means being constructed and arranged to oppose the spring for retarding the movement of the drawer into its open position so that a sudden impact in its open position is prevented; said damping means comprising a variable volume chamber coupled to the drawer to increase a volume of the chamber as the drawer is opened and decrease said volume as the drawer is closed; a check valve disposed between said chamber and the atmosphere, said check valve being arranged to open as said volume is decreased, said check valve having a check valve cross-sectional area; and a restricted air passage by-passing said check-valve to permit air exchange between the chamber and atmosphere and having a passage cross-sectional area smaller than the check valve cross-sectional area.
Claim 3
