Abstract:
A door closer, comprising a door closer housing mounted to one of a door frame or a door surface and a linkage arm for pivoting the door between open and closed positions. The linkage arm has a first and second end, the first end mounted to the other of the door frame or the door surface. The door closer includes a rotatable connector between the linkage arm and the door closer housing, the linkage arm second end engaging with the rotatable connector. The connector has a rotatable body portion and head protrusion substantially secured in a female receptor to transmit rotation about a longitudinal axis of the connector. One or both of the head protrusion or female receptor has a curved profile and is further movable with respect to the head protrusion to permit limited rotational misalignment of the linkage arm on any axis perpendicular to the connector longitudinal axis.

Abstract:
Die Erfindung betrifft eine Antriebsvorrichtung (20) für Ein-/Ausstiegseinrichtungen für Fahrzeuge des öffentlichen Personenverkehrs, mit einer Antriebseinheit (22), die in einer sich bei Öffnungs- und Schließvorgängen um eine Rotationsachse Z-Z drehenden Drehsäule (24), die die Ein-/Ausstiegseinrichtung öffnet und schließt, angeordnet ist und diese antreibt. Dabei ist die Antriebseinheit (22) über ein Haltebauteil (40) am Fahrzeug gehalten und das Haltebauteil (40) wirkt als Gegenlager für ein Drehmoment der Antriebseinheit (22). Zwischen der Antriebseinheit (22) und dem Haltebauteil (40) ist eine Kupplungsvorrichtung (72) angeordnet, die bei Überschreiten eines Grenzwertes des auf die Antriebseinheit wirkenden Drehmoments eine Rotation der Antriebseinheit (22) um die Rotationsachse Z-Z ermöglicht.
Abstract:
A linear actuator for gates, doors or similar has an actuator arm (1) which is articulated to a support (3) around a vertical axis (15) and be raisable angularly around a horizontal inclination axis (16). The actuator arm (1) has a screw (7) which is operated by an electric motor (11) and a running nutscrew (8) articulated to the gate wing (5) by means of a leadnut holder (18) in which the nutscrew (8) is housed in a manner turning around an axis horizontal and transversal to the actuator arm (1). The leadnut holder (18) has a vertical lower articulation pivot (20) which engages from above in a turning manner in a bush (22) fastened to the wing (5). In an emergency the actuator is disengaged from the gate wing (5) by raising the actuator arm (1) angularly around its inclination axis (16) and extracting upward the articulation pivot (20) of the leadnut holder (18) from the bush (22).

Abstract:
The invention relates to a swing-gate articulated-arm drive linkage (12), comprising a first articulated arm (14) and a second articulated arm (16), wherein the first articulated arm (14) can be connected at a first end (18) to a motor drive unit (54) of a swing-gate articulated-arm drive (46) for driving a rotational motion of the first articulated arm (14) about a first axis of rotation (58) and is connected at the second end (20) to a first end of the second articulated arm (22) by means of an articulated-arm joint (24) in such a way that the first and the second articulated arm (14, 16) can be rotated in relation to each other about a second axis of rotation (60), which extends substantially parallel to the first axis of rotation (58), wherein the second articulated arm (16) is to be connected at a second end (26) thereof, by means of a gate joint (28), to a swing-gate leaf (42) of a swing gate (40) to be driven. In order to be able to drive a larger variety of swing gates in a simple and safe manner and with low maintenance, it is proposed that the articulated-arm joint (24) is a multi-axis joint (70), which also permits, in addition to the relative rotation of the first articulated arm (14) and the second articulated arm (16) about the second axis of rotation (60), a relative pivoting of the first and the second articulated arm (14, 16) about at least one additional axis (74).
