Claims13
A corner bracket for a vertical moving door, the corner bracket comprising:
- a base plate configured to be attached to the door;
- and
- a guide path for a lift cable having a circular extension and arranged along a periphery of the base plate including an aperture extending radially outward through the circular extension between opposite ends of the guide path;
- a switch arranged in the base plate radially inward of the circular extension and configured to be actuated by the lift cable in the event of a breakage of the lift cable;
- and
- a control element connected with the switch at a first end and extending through the aperture, wherein an opposite end of the control element contacts the lift cable when the lift cable is disposed along the guide path.
A method, performed by a control device, for stopping a vertical moving door of a vertical moving door system, the vertical moving door system comprising:
- at least two lift cables, a motor and at least two corner brackets, the at least two corner brackets each comprising:
- a base plate configured to be attached to the door;
- a guide path for a lift cable having a circular extension and arranged along a periphery of the base plate including an aperture extending radially outward of the circular extension between opposite ends of the guide path;;
- and
- a switch arranged in the base plate radially inward of the circular extension and
- a control element connected with the switch at a first end and extending through the aperture, wherein an opposite end of the control element contacts the lift cable when the lift cable is disposed along the guide path,
- wherein the switches and control elements of the respective corner brackets are and configured to be actuated by the lift cable in the event of a breakage of the lift cable, wherein the respective at least two lift cables are connected to the motor and to the at least two corner brackets and wherein the motor is configured to move the vertical moving door by the at least two lift cables between an open and closed position (O, C), the method comprises the steps of:
- receiving a signal from the switch in the event of a breakage of the lift cable, and
- controlling the motor to stop the movement of the vertical moving door.
