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

摘要

#CMT# #/CMT# 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. #CMT#USE : #/CMT# Additional door i.e. insect protection door (claimed), for use in a balcony area and a terrace area. #CMT#ADVANTAGE : #/CMT# The retraction element builds the restoring force during moving the slide wing from the closing position, thus automatically bringing the slide wing into the closing position, and hence completely closing the door without gaps. The traction unit and the retraction element are arranged in the housing that is laterally fastened at the frame, thus providing a compact additional door. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic side view of a part of an additional door in a partially opened condition. 1 : Additional door 2 : Position-fixed frame 4 : Slide wing 10 : Housing 11 : Retraction element 12 : Spiral spring 15 : Traction unit 16 : Band 23 : Deflection rollers.
