Abstract
A break-out door sensor system is provided. In one aspect, the system includes: a door; a sensor located on the door; a trigger connected to the door and located proximate to the sensor and configured to move to an actuating position, and when in the actuating position, the trigger contacts the sensor causing the sensor to emit a signal, the trigger being biased away from the actuating position; and a camming surface on the trigger, wherein dimensions of the trigger and the trigger's location on the door with respect to the sensor including the location and dimensions of the camming surface are selected to cause the trigger to move to the actuating position when the camming surface moves against door guide forming a channel and the trigger moves out of the channel.
Claims20
A door sensor system comprising:
- a door;
- a sensor located on and configured to move with the door;
- a trigger connected to the door and located proximate to the sensor and configured to move to an actuating position, and when in the actuating position, the trigger contacts the sensor causing the sensor to emit a signal, the trigger being biased away from the actuating position;
- and
- a camming surface on the trigger, wherein dimensions of the trigger and the trigger's location on the door with respect to the sensor including the location and dimensions of the camming surface cause the trigger to move to the actuating position when the camming surface moves against a door guide forming a channel and the trigger moves out of the channel.
A door sensor system comprising:
- a door mounted over an opening, the door configured to move between open and closed positions to allow and deny access through the opening;
- a door guide forming a channel located to a side of the opening;
- a sensor located on and configured to move with the door;
- a trigger connected to the door and located proximate to the sensor and configured to move to an actuating position, and when in the actuating position, the trigger contacts the sensor causing the sensor to emit a signal, the trigger being biased away from the actuating position;
- and
- a camming surface on the trigger, wherein dimensions of the trigger and the trigger's location on the door with respect to the sensor including the location and dimensions of the camming surface are selected to cause the trigger to move to the actuating position when the camming surface slides against the door guide channel and when the trigger moves out of the channel.
