Abstract
An automatic door operating safety system particularly used with garage doors is provided. A security timer for a powered overhead garage door causes the door to close after it has been opened for a predetermined time interval. Before timeout, the system will determine by its various sensors whether there is any activity within the area. Upon the absence of such activity the system signals the command for door closure.
Claims12
A garage door operator for use with a garage having a path of door travel area and a general garage area, the operator comprising:
- an electric motor;
- a transmission connectable to said motor for connection to a garage door to open and close said door through the travel area;
- a control unit connected to said motor to command said motor to open and close said door;
- an auto closure module including a timing unit for timing a period in which said door is in an opened position, said module capable of actuating said control unit to close said door after said period has timed out;
- and
- a vehicle detector for determining whether activity is present within the general garage area, said detector being an audio detector, upon activity detection said detector being further capable of disabling said module from automatically closing the door upon timing out.
A retro-fit automatic safety garage door closer to be used with existing door operators having a motor and a transmission connecting the motor to the door to open and close the door through a path of door travel area, the automatic closer comprising:
- a control unit connected to said motor to command said motor to open and close said door;
- an auto closure module including a timing unit for timing a period in which said door is in an opened position, said module capable of actuating said control unit to close said door after said period has timed out;
- and
- a vehicle detector for determining whether activity is present within the general garage area, said detector being an audio detector, upon activity detection said detector being further capable of disabling said module from automatically closing the door upon timing out.
A garage door operator for use with a garage having a path of door travel area and a general garage area, the operator comprising:
- an electric motor;
- a transmission connectable to said motor for connection to a garage door to open and close said door through the travel area;
- a control unit connected to said motor to command said motor to open and close said door;
- an auto closure module including a variable timing unit for timing a period in which said door is in an opened position, said module capable of actuating said control unit to close said door after said period has timed out;
- a vehicle detector for determining whether any activity is present within the general garage area, said detector being a thermal detector, upon activity detection said detector being further capable of disabling said module from automatically closing the door upon timing out.
