Fig. 1 shows a door opener 1, which has a door opener housing 11. The door opener housing 11 is formed substantially cuboid and has a removable cover 12. The door opener 1 can be installed in a fixed frame of a door or a grand piano. It can be installed in particular in a castle counter box or connected to a strike plate. For this purpose, the door opener housing 11 his front side two mounting holes 13a and 13b. These are in the representation of Fig. 1 arranged left and right of a door opener housing 14 pivotally mounted in the door opener housing 11.

At a lateral end, the door opener 1 has a connection device 3, to which a detection device 4 is connected. The detection device 4 is mechanically fixed and detachably connected to the housing 11 of the door opener 1 via the connection device 3. A mechanical receptacle of the connection device 3 is designed as a screw connection 31 and serves to selectively connect the detection device 4 formed as a separate structural unit to the door opener housing 11 or to release it again from the door opener housing 11. The detection device 4 is designed as a module in that the detection device 4 has a separate housing 43, in which all components of the detection device 4 are accommodated. Via an electrical connection line, the detection device 4 can be connected to a higher-level control device or an access control center.

In Fig. 2 is a schematic exploded view of the door opener 1 is shown. To clarify the arrangement of the components of the door opener was in Fig. 2 the cover 12 of the door opener removed. The door opener 1 has a blocking device 2, which is acted upon by an electrically actuable actuator to lock the door latch 14 or release. The electrical actuator is powered by a terminal block 16 which is arranged accessible to the door opener housing 1 from the outside. The terminal block 16 is arranged on the end of the Türöfnergehäuses 11 opposite the connection device of the detection device 4. The terminal block 16 is in addition to the connection device of Detection device provided and not removable from the door opener housing 11 formed.

The blocking device 2 comprises an armature 21, which is movably mounted in the door opener housing 11 and cooperates with a change 22 movably mounted in the door opener housing 11. The movable armature 21 is urged by an actuator and pivoted about a pivot axis so that it comes to rest out of engagement with the change or in engagement with the change. When the armature 21 is engaged with the change 22, the armature 21 blocks pivotal movement of the change 22 and thus locks the door opener catch 14, since the strike latch 14 bears directly against the change 22 with a projection.

In the FIG. 3 is the door opener with locked or locked door opener trap shown and in FIG. 4 the door opener is shown with released door opener trap. When the door opener latch is released, the armature 21 is pivoted outward in the direction of the outer wall of the door opener housing 11 and thus releases the movable change 22. As a result, the door opener 14 can now be pivoted by the door latch 14 pushes the now freely movable change against the force of the changeover spring 23. The changeover spring 23 is provided so that in the neutral position of the change 22 the door opener 14 is returned to its neutral position.

The door opener housing 11 has a connection device 3 arranged in the region of the movably mounted armature 21, to which the detection device 4 can be connected. The connection device 3 is mounted on the outside of the door opener housing 11. The detection device 4 is arranged outside the door opener housing. It has a housing 43 in which a recess 44 is arranged for a sensor. The sensor 41 is designed as a microswitch with switching lug 42. The microswitch 41 is received in the exception 44 of the housing 43 and fixedly connected to the housing 43. It thus forms a separate structural unit, which is completely removable from the door opener housing 11 or can be connected to the door opener housing 11 on request. The connection device 3 has a screw connection 31, which serves as a mechanical receptacle for the detection device 4 to connect them releasably and yet mechanically fixed to the door opener housing 11. Next, the connection device 3 has a arranged in the wall of the door opener housing 11 section with a recess 32 through which the sensor 41 and the switching lug 42 of the micro switch 41 engages. The switching flag is 42 in any position of the armature 21 in contact with this, as in the Fig. 3 or 4 shown.

In the Fig. 3 the locked position of the door opener is shown. The armature 21 has a projection which is pivoted into the range of movement of the change 22 and the change 22 engages directly at its frontal end to block its movement. The change 22 is thus defined in its range of motion.

In the presentation of the Fig. 4 the movably mounted armature 21 is pivoted toward the wall of the door opener housing 11. At the same time, the projection of the armature 41 is disengaged from the change 22, so that the change 22 can now escape when acted upon by the pivotally mounted door latch 14 and trap thus the door opener latch 14 is freely pivotable about its pivot axis 15.

The switch 41 of the detection device 4 is designed as a changeover switch, so that it can be connected either as a normally open (NO) or normally closed switch (NC). The connections of the switch are led out of the detection device 4 via a cable connection and led to a distributor or to a higher-level control device.

The detection device 4 can be connected by simple handles firmly with the door opener housing 11 or be solved by the door opener housing 11. It is designed as a separate unit that can be easily replaced or even with already installed door opener is easy to retrofit. In the region of the connection device 3, a section with a recess 32 is arranged in the wall of the door opener housing 11, through which the sensor 41 engages with its switching lug 42 in order to detect the position of the armature 21. In order to prevent soiling of the components stored inside the door opener housing when the detection device 4 is absent or removed, it is provided that the material-free region 32 can be covered by a cap.
