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 retracting device used for a vane fan of a door or a window. The retracting device comprises a housing, a piston loaded with a spring unit and a drive component matching a pin bolt of the vane fan or a framework. A buffer space and a non-pressure space are arranged on the side oppositely of the piston. The drive component is coupled to the spring unit and guided in a chute guide device of the housing such that the drive component is driven by the pin bolt till the vane fan is opened to the pre-set flare angle of the vane fan while the spring unit is pressed. At the pre-set flare angle, the drive component deviates at the terminal position beyond the dead point. In the terminal position, the drive component releases the pin bolt and is kept by the spring unit. The drive component deviates again by the pin bolt till the closed vane fan reaches the pre-set flare angle such that the released and pressed spring unit can close the vane fan in a buffering mode under action of the spring unit by means of the piston.

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...
