Description

The present invention relates to a swing door operator attachment (hereinafter referred to as attachment) to supplement a door drive and a swing door operator assembly comprising a door drive and the attachment.

The prior art knows door drives which drive via a rotary shaft and a linkage of a revolving door. In this case, the rotary shaft is operated by motor or motor underestimated to open and / or close the door. Often, these door drives have no or only very weak spring energy storage. Furthermore, usually no damper or only a weak damper for the opening and / or closing movement is provided.

It is an object of the present invention to provide a swing door actuator attachment, which complements a door drive to a spring accumulator with simple and cost-effective production and assembly. Preferably, the swing door actuator attachment should allow an opening and / or closing damping.

Furthermore, the attachment comprises a housing arranged in the spring unit as energy storage for a closing or opening movement of the swing door, wherein the spring unit is connected to the mutual power transmission to the driven pulley. By mounting the attachment according to the invention on a door drive, it is sufficient that the door drive only drives the opening or closing direction of the door. The other direction can be driven by means of the spring in the essay. Alternatively, the door drive can also be designed for the motor drive of the opening and closing direction of the door. The spring energy accumulator in the attachment then serves to open or close the door, for example in the event of a power failure and / or in the event of fire.

The previously known door opener or door closer usually consist of a cast housing, in which a closing spring and a drive mechanism is housed. An output shaft extends out of the casting housing. On this output shaft, a lever is mounted outside of the cast housing. This lever transmits the force on the door leaf or door leaf on the door frame. These prior art door operators are complex and expensive to manufacture due to the cast housing. Furthermore, the cast housing is very high, so that the previously known door openers or door closers are not suitable as an attachment to a door drive. In particular, it requires for the or the damper in the article of the invention a new design. The attachment therefore preferably comprises at least one damper arranged in the housing for damping the closing and / or opening movement of the swing door, wherein the damper is connected to the driven pulley for mutual transmission of power and is designed as a separate module independent of the housing.

In the following, for reasons of clarity, there is usually talk of a damper. Likewise, it is preferably provided that a plurality of dampers are arranged both in parallel and in series.

Preferably, the shaft extends through the cover plate and / or base plate and thus provides an interface for the lever and / or for the rotary shaft of the door drive. Preferably, the shaft extends through the cover plate and the base plate. Thus, the essay can be used on both sides, ie for DIN left and DIN right. Furthermore, thus, the essay can also be mounted between the door drive and the lever or linkage.

Particularly preferably, the housing, in particular the connection of base plate and cover plate, not formed fluid-tight and not gas-tight. The fact that the damper is used as an independent and self-contained module, it requires no dense execution of the housing. As a result, the article according to the invention can be produced very simply and inexpensively.
