Embodiment Construction

[0034] exist figure 1 The door closer 11 which is only partly shown in the figure can be configured as an upper door closer or a lower door closer and comprises an elongated door closer housing 13 in which a not shown door closer housing is rotatably supported. A door closer shaft that can be coupled to a leaf of a pivoting door. The door closer housing 13 forms a hydraulic cylinder filled with damping medium, in an inner chamber 15 of which a piston 17 is guided which is movable against the pretension of the door closer spring. A pinion, not shown, fixedly connected to the door closer shaft meshes with the toothed rack of the piston 17 and is responsible for the movement of the piston 17 when the door closer shaft turns and vice versa.

[0035] The door closer housing 13 is in a figure 1 On the upper face of the housing there is a housing opening 19 which is circular here corresponding to the cross-section of the inner chamber 15 . The housing opening 19 is closed by a cov...

Abstract

The present invention relates to a door closer which includes a door closer housing which is further provided with a housing hole, the housing hole being closable by a lid, wherein the lid has an elastically deformable retaining section, the lid being clamped and / or tightened within a lid seat of the door closer housing.

Description

technical field [0001] The invention relates to a door closer having a door closer housing with a housing opening which is closed by a cover. Background technique [0002] Door closers are known, for example, in the form of upper or lower door closers and serve to automatically reclose a door leaf after it has been opened and then released. For this purpose, a closing element, for example a closing shaft, is usually movably mounted in the door closer housing, which can be coupled to the door leaf or the associated door frame. Furthermore, a closer drive, for example a closer spring, is accommodated in the door closer housing, which provides the closing force. [0003] When manufacturing the door closer, the components to be placed in the housing of the door closer can be introduced through the housing hole. In addition, the interior of the door closer housing is often filled with a damping fluid, which can likewise be done through the housing bore. Finally the housing ope...
