Friction damper used to arrest sliding door, comprises casing containing plate deflecting progressively against resilient elastomer as door finger advances

摘要

The attachment plate (2) is electrically-welded (10) to the metal casing (1) which contains the damping system (4, 3). This comprises a metal plate (4) which can be moved. It is able to retain the door finger (5). The plate is adhered to a molded elastomer spring (3). The angle of the plate (4) varies progressively as the door finger (5) penetrates, and can even become negative at the end of its path.
