Additional door, in particular fly screen door, with an automatic closing mechanism

摘要

The door (1) has a slide wing (4) displaceably provided in a position-fixed frame (2). The wing is connected with a retraction element (11) e.g. spiral spring (12), by a traction unit (15) e.g. band (16). The retraction element builds restoring force during moving the wing from a closing position. The traction unit and the retraction element are arranged in a housing (10), which is laterally fastened at the frame. The traction unit is guided towards the wing by deflection rollers (23). A damping element i.e. brush, damps resetting movement of the wing during entering into the closing position.
