Problems solved by technology

[0002] Problems often arise when closing doors without door closers: the door is closed incorrectly and the door remains open, as a result of which drafts may be generated in the space concerned
If the door is closed too strongly, the door strikes heavily against the fixed frame, thereby causing noise and possible damage to components such as the corresponding door lock

Embodiment Construction

[0035] Figures 1 to 16 An exemplary embodiment of a retracting device 10 according to the invention for a door leaf 12 is shown schematically.

[0036] The pull-in device 10 comprises, for example, a housing 18 which can be mounted here on a fixed frame 16 , a piston 24 which is arranged in a receiving space 20 of the housing 18 and which is loaded by a spring unit 22 , and which in this case can be mounted, for example, on a A pin 30 on the leaf 12 or a similar cooperating drive element 32 is provided with a damping space 26 and a pressure-free space 28 on opposite sides of the piston.

[0037] The entraining element 32 is coupled to the spring unit 22 and is guided in the link guide 34 of the housing 18 in such a way that when the leaf 12 is opened up to a predetermined opening angle of the leaf 12 it is entrained by the pin 30 and at the same time The spring unit 22 is compressed, and when the predetermined opening angle is reached, the carrier is deflected beyond the dea...

Abstract

The invention relates to a pull-in device for a leaf of a door or a window, which comprises a housing, a piston loaded by a spring unit and a driver cooperating with a pin on the leaf or on the frame, between the pistons A buffer space and a pressure-free space are provided on the opposite side, the entraining element is coupled to the spring unit and is guided in the slot guide of the housing in such a way that when the leaf is opened to a predetermined opening angle of the leaf, the entraining element is driven by the The bolt entrains and simultaneously compresses the spring unit, and when the predetermined opening angle is reached, the driver deflects beyond the dead center position into an end position in which the driver releases the bolt and is held by the compressed spring unit, The entrainment element is deflected back again by the pin until the predetermined opening angle is reached when the leaf is subsequently closed, in order to release the compressed spring unit and to close the leaf cushioned by the piston via the pin under the action of the spring unit.

Description

technical field [0001] The invention relates to a pull-in device for a door or window leaf. Background technique [0002] Problems often arise when closing doors that are not equipped with a door closer: the door is closed incorrectly and the door remains open, whereby drafts can be generated in the associated space. If the door is closed too strongly, the door strikes heavily against the fixed frame, thereby causing noise and possible damage to components, such as the corresponding door lock. Contents of the invention [0003] The object of the present invention is to provide a retracting device for a leaf of a door or a window, with which the leaf remains largely free of movement in an as compact construction as possible. , but always ensure a reliable and cushioned closing of the wings. [0004] For this reason, the present invention provides a kind of pull-in device for the leaf of door or window, and this pull-in device comprises the shell that can be installed on t...
