AUTOMATIC DOOR WITH EMERGENCY RESCUE SYSTEM

摘要

Automatic doors have become commonplace in hospitals or retirement homes to facilitate entry into auxiliary rooms, such as bathrooms. Unfortunately, when a patient becomes incapacitated inside the bathroom, the door often becomes obstructed by the patient, making entry into the bathroom through the door impossible without further injuring the patient. In many instances removal of adjacent walls is required to gain entry into the room. The automatic door of the present invention includes a retractable door stop enabling reverse rotation of the door, and sensors for automatically setting and resetting the automatic door controls when the door is opened and closed in either direction.

主权项

1. An automatic door system for mounting in an opening to a room comprising:
a door mounted in a frame in the opening, pivotable in a first direction from a closed position into the room to an open position during normal operation; an automatic door opening device for rotating the door into the open position in response to a first signal; a lockset in the door including:
a retractable latch for engaging the frame,a latch control for retracting the latch in response to a first signal,first and second rotatable manual actuators for manually retracting the latch enabling the door to be opened manually from inside or outside the room, respectively, anda manual actuator lock for preventing the second rotatable manual actuator from being rotated from outside the room in response to a second signal; a first switch for mounting outside the room for activating the first signal for actuating the latch control to retract the latch, and for activating the automatic door opening device to open the door; a second switch for mounting inside the room for activating the first signal to actuate the latch control to retract the latch, and for activating the automatic door opening device to open the door, respectively; a door locking switch for mounting inside the room for deactivating the first switch preventing the automatic door opening device from being activated, and for activating the second signal to actuate the manual actuator lock to prevent the second manual actuator from being rotated from outside the room; a retractable door stop moveable from an extended position to a retracted position for preventing the door from pivoting in a direction opposite the first direction out of the room when in the extended position, and for enabling the door to open in the opposite direction out of the room when in the retracted position; a first sensor for re-activating the first switch and for deactivating the manual actuator lock, when the door is opened from the inside from the closed position; and a second sensor for determining when the door has been rotated in the opposite direction outside of the room for deactivating the first and second switches to prevent them from activating the automatic door opening device.
