The invention relates to an electrically actuated door opener for opening a door. Said door opener comprises a pivotable catch that is designed to retain or release a bolt, a locking lever, and a switch which can be moved between a position blocking the pivotable catch and a position releasing the pivotable catch. The switch is disposed in such a way in relation to the locking lever that the switch can be blocked by the locking lever in the blocking position. The door opener further comprises an actuator which allows the locking lever to be moved from the position blocking the switch into a position releasing the switch. The invention also relates to a method for unlocking such a door opener.

The invention relates to an electrically actuatable door opener (1) comprising a pivot latch (4) for holding or releasing a door-side snap latch with a moving stop lever (8) and with a switchover (7), which can move between a position that blocks the pivot latch (4) and a position that releases the pivot latch (4) and which interacts with the stop lever (8) in such a manner that the switchover (7) can be locked in the blocking position by means of the stop lever (8). In addition, a positioning element (16) is provided for moving the stop lever (8) in order to lock or release the changeover (7). The positioning element (16) comprises an electric motor (16), and a centrifugal force eccentric (17) is mounted on the axle of the electric motor. The electric motor is placed in the vicinity of the stop lever in order to, when the electric motor (16) is activated, strike the centrifugal force eccentric (17) against the stop lever (8) due to the rotation of the motor axle whereby moving the stop lever (8).

The invention relates to an impact-resistant door opener (1), comprising a door opener latch (12) mounted in a housing and comprising a locking device, which can be remotely actuated and which has a coil (22) and a linearly movable tappet (23) in order to switch a rotatably mounted locking lever (24) between a locking position, in which the door opener latch (12) is locked, and a release position, in which the door opener latch is released. In order to achieve a robust construction and a high level of manipulation security, the locking lever (24), according to the invention, has two lever arms (241, 242) angled to each other, wherein the first lever arm (241) interacts with a switching element (13) and the second lever arm (242) protrudes in the direction of the tappet (23) and, in the locking position, interacts with a securing stop (25), which can be actuated by the coil (22), in order to prevent a release of the switching element (13) as a result of shaking or strikes.

The invention relates to a locking/release device for a pivoting catch (5) for a door opener (15), comprising a locking lever (4) which locks or releases the pivoting catch (5), and a safety lever (1) which maintains the locking lever (4) in a locked position. The locking lever (4) can be pivoted in a releasing position with the aid of an electromagnet (3). The safety lever (1) is mounted in the centre point of the mass thereof. A safety lever (1) is thus required for the impact security of the door opener, the susceptibility to vibration and shaking can be reduced thus producing a compact arrangement. In a preferred embodiment, the safety lever (1) comprises two lever arms (6, 7). The electromagnet (3) interacts with the one lever arm (7) and a pressure spring (11) interacts with the other lever arm (6). The device can be built in any position.

Die Erfindung betrifft einen Türöffner (1) mit einer in einem Türöffnergehäuse (11) schwenkbar gelagerten Türöffnerfalle (12) und einer fernbetätigbaren Sperreinrichtung, die einen Aktor (13) und einen drehbar gelagerten Wechsel (2) aufweist, der zwischen einer Sperrposition, in der die Türöffnerfalle (12) gesperrt ist, und einer Freigabeposition, in der die Türöffnerfalle (12) freigegeben ist, durch den Aktor (13) schaltbar ist. Um einen Türöffner (1) zu schaffen, der einerseits eine hohe Haltekraft und andererseits eine hohe Funktionssicherheit aufweist, wird vorgeschlagen, dass zwischen Anker (3) und Wechsel (2) ein kraftübertragendes Element (4) angeordnet ist, welches in der Sperrposition direkt an dem Wechsel (2) und direkt an dem Anker (3) anliegt und entweder an dem Anker (3) oder an dem Wechsel (2) schwimmend gelagert ist.
