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.

A device for moving at least one door leaf, includes a fixed beam that is fixed to the frame, a moving beam that is connected to the fixed beam by swinging rails which allow it to move transversely with respect to the axes of elongation of the fixed and moving beams, a motor which drives the leaf in a movement parallel to the axis of elongation of the moving beam and which, during the swinging of the leaf, also drives a drive cam which is provided with a slot in which there is engaged a pin that is fixed to the fixed beam, and a central roller which is connected to the moving beam and circulates in a groove in the fixed beam during the movement of the leaf.

A device for a frameless vehicle door includes a counter bearing, a guide rail mounted thereon for a window regulator, and an adjusting device for inclining the guide rail along an adjusting direction oriented obliquely to the counter bearing. The adjusting device can be actuated by a tool. An access direction of the tool is oriented obliquely to the adjusting direction. The adjusting device has at least two adjusting components that can be moved relative to one another, namely, a threaded bolt oriented along the adjusting direction and at least one threaded nut screwed thereon. One of the adjusting components is fixed to the guide rail or the counter bearing for conjoint rotation, and the other is rotatably mounted. The rotatably mounted adjusting component has a drive contour and can be driven by to axially adjust the adjusting components with respect to one another along the adjusting direction.

A hinge for a flap of a motor vehicle includes a flap element which is designed to be secured to the flap. A pivoting element is designed to be secured to a body of the motor vehicle such as to be rotatable about a hinge axis, wherein in a first location the flap element is connected to the pivoting element so as to be rotatable about a rotational axis, and in a second location, which is offset relative to the first location, the flap element is connected to the pivoting element via a releasable securing element. A spacer maintains a distance between the pivoting element and the flap element in an installed position, in which the securing element is released and the flap element is rotated relative to the pivoting element about the rotational axis in comparison to a normal position.
