Embodiment Construction

[0017] The drawing shows a drive device 1 by means of which a revolving door, not shown, is opened and closed as an operating element. The drive device 1 includes an electric drive designed as a motor with gear, which is integrated in a motor housing 2 . The motor housing 2 is mounted on a bracket, which is formed by a rod element 3 fastened to a base plate 4 . An attachment 5 made of steel emerges from the bottom of the base plate 4 , by means of which the drive unit 1 is attached to a doorpost or the like.

[0018] A spindle 6 in the form of a threaded screw is driven by the drive. In this case, the spindle 6 is moved rotationally about its longitudinal axis by means of the drive. Depending on the direction of rotation of the spindle 6, the revolving door is opened or closed. A further threaded spindle 7 extends parallel to the driven spindle 6 , on which threaded spindle 7 is arranged a limit switch 8 for the terminal control of the revolving door.

[0019] The drive is...

Abstract

The invention relates to a drive apparatus having a spindle (6) which is driven by a drive for actuating an actuating element. Supporting means are provided which are connected fixedly to the spindle (6) and can be moved against a spring bearing. If forces which exceed a predefined maximum value act on the spindle (6), the spring bearing is compressed and the supporting means are pressed against a stationary stop. As a result, the drive is decoupled from these forces.

Description

technical field [0001] The invention relates to a drive device according to the preamble of claim 1 . Background technique [0002] Such a drive can typically be configured as a propulsion spindle drive, a spindle reciprocating drive, or the like. In particular, the drive device can be designed as a swing door drive, wherein a spindle for closing and opening the swing door is driven by means of a drive designed as a motor with a drive. Such a revolving door for closing hall entrances and the like has a relatively large area in the order of several square meters. Correspondingly, such a door forms a large area of ​​action for the wind, through which high forces can be exerted on the door. Very high forces can also be exerted on the drive by an external force acting on the closing edge of the door. [0003] It is known in drives of this type to carry out an emergency stop when such a force is generated in order to thereby stop the door and thereby possibly avoid dangerous d...
