Abstract
A door drive mechanism includes a main drive and an auxiliary drive. In this connection it is provided that the drive assembly of the auxiliary drive is formed as a drive assembly with a linear output and that the drive assembly of the auxiliary drive is borne in a pivot bearing and that the rod system is formed as a slide arm and the rod system bearing is formed as a slide rail.
Claims33
A door drive mechanism for a door of a building with a door leaf borne pivotably about a vertical door axis in a stationary frame, comprising:
- a) a main drive for acting on the door leaf in the direction of the closing movement and/or opening movement and/or closing damping and/or opening damping, preferably formed as a manual closing spring drive or as an electric-motor door drive, the main drive comprising:
- a1) a drive assembly of the main drive and
- a2) a force-transmitting mechanism of the main drive with a rod system and a rod system bearing,
- b) an auxiliary drive for acting on the door leaf in the direction of the closing movement and/or opening movement and/or closing damping and/or opening damping the auxiliary drive comprising:
- b1) a drive assembly of the auxiliary drive and
- b2) a force-transmitting mechanism of the auxiliary drive, which has a rod system and a rod system bearing and can be coupled in and out automatically with the drive assembly of the auxiliary drive during the opening and closing process,
- wherein the coupling-in/out point is formed between the rod system and the rod system bearing, or
- wherein the coupling-in/out point is formed between the rod system and the drive assembly of the auxiliary drive, and, characterized in that
- wherein the drive assembly of the auxiliary drive is formed as a drive assembly with a linear output,
- the drive assembly, as auxiliary drive, is borne in a pivot bearing,
- the rod system is formed as a slide arm and the rod system bearing is formed as a slide rail;
- wherein the slide arm has an end, assigned to the rod system bearing, which is guided in the rod system bearing formed as a slide rail;
- wherein the slide arm has a first connecting end, facing the drive assembly of the auxiliary drive, which is formed for connection to the linear output of the drive assembly;
- wherein the slide arm has a second connecting end, which is supported in a pivot bearing which is formed stationary with the pivot bearing in which the drive assembly of the auxiliary drive is borne pivotably.
A door drive mechanism for a door of a building with a door leaf borne pivotably about a vertical door axis in a stationary frame, comprising:
- a) a main drive for acting on the door leaf in the direction of the closing movement and/or opening movement and/or closing damping and/or opening damping, the main drive comprising:
- a1) a drive assembly of the main drive and
- a2) a force-transmitting mechanism of the main drive with a rod system and a rod system bearing,
- b) an auxiliary drive for acting on the door leaf in the direction of the closing movement and/or opening movement and/or closing damping and/or opening damping the auxiliary drive comprising:
- b1) a drive assembly of the auxiliary drive and
- b2) a force-transmitting mechanism of the auxiliary drive, which has a rod system and a rod system bearing and can be coupled in and out automatically with the drive assembly of the auxiliary drive during the opening and closing process,
- wherein the coupling-in/out point is formed between the rod system and the rod system bearing, or
- wherein the coupling-in/out point is formed between the rod system and the drive assembly of the auxiliary drive,
- wherein
- the drive assembly of the auxiliary drive is formed as a drive assembly with a linear output,
- the drive assembly of the auxiliary drive is borne in or on a slide rail or adjoining a slide rail, in which the linear output of the drive assembly is guided,
- the rod system is formed as a slide arm and the rod system bearing is formed as a pivot bearing,
- wherein the slide arm has an end, assigned to the rod system bearing, which is borne pivotably in the rod system bearing formed as a pivot bearing,
- wherein the slide arm has an end, facing the drive assembly of the auxiliary drive, which is formed for connection to the output of the drive assembly of the auxiliary drive guided in the slide rail.
The door drive mechanism according to claim wherein the first segment and the second segment of the angular arm are formed as separate components, the position of which relative to each other is variably adjustable by means of an adjusting mechanism.
