Abstract
A separating device for a door leaf that is moveable overhead has a coupling element movable between a coupling position, in which the coupling element couples an output element of the drive device to the structural component, and a freewheeling position, in which the output element of the drive device is decoupled from the structural component. A locking member is provided which is movable between at least one release position, in which the locking member allows a movement of the coupling element into the freewheeling position, and at least one locking position, in which the locking member counteracts a movement of the coupling element into the freewheeling position. The locking member can be coupled to the drive device.
Claims9
A separating device for a door having a door leaf and a drive device for moving said door leaf overhead, said drive device comprising a gear and an output element wherein the separating device comprises:
- a coupling element movable between a coupling position, in which the coupling element is adapted to couple the output element to the door leaf, and a freewheeling position, in which the output element is adapted to be uncoupled from the door leaf;
- a locking member movable between at least one release position, in which the locking member is configured to allow a movement of the coupling element into the freewheeling position, and at least one locking position, in which the locking member counteracts the movement of the coupling element into the freewheeling position;
- wherein the locking member is configured to be coupled to the drive device, said separating device further comprising a rotatably supported control shaft, said locking member is rotationally coupled by the control shaft to the output element and said output element is rotationally coupled to a rotatably supported drive shaft, said separating device further comprising a locking element correlated with the locking member, wherein the locking element cooperates with the locking member in the locking position of the locking member and counteracts the movement of the coupling element into the freewheeling position, said locking member having a locking disc that has a groove and said locking element has a projection configured to be introduced into the groove in the release position of the locking member.
A separating device for a door having a door leaf and a drive device for moving said door leaf overhead, said drive device comprising a gear and an output element, wherein the separating device comprises:
- a coupling element movable between a coupling position, in which the coupling element is adapted to couple the output element to the door leaf, and a freewheeling position, in which the output element is adapted to be uncoupled from the door leaf;
- a locking member movable between at least one release position, in which the locking member is configured to allow a movement of the coupling element into the freewheeling position, and at least one locking position, in which the locking member counteracts the movement of the coupling element into the freewheeling position;
- wherein the locking member is configured to be coupled to the drive device, further comprising a rotatably supported control shaft, wherein the locking member is rotationally coupled by the control shaft to the output element, wherein the output element is rotationally coupled to a rotatably supported drive shaft for the door, further comprising a locking element correlated with the locking member, wherein the locking element, in cooperation with the locking member in the locking position of the locking member, counteracts the movement of the coupling element into the freewheeling position, further comprising an actuating device for moving the coupling element, wherein the locking element is arranged on the actuating device, wherein the actuating device comprises at least one driver engaging a groove extending peripherally about the coupling ring.
