Security automatic garage door closer
First Claim
1. A security kit for a garage door operator comprising a reversible electric motor operable to open and close a garage door along a path, a wall switch connected to said electric motor with a pair of conductors for operating said electric motor, and safety apparatus for preventing said garage door from closing on an obstruction in the path of said garage door when said garage door is closing, said security kit comprising:
- a replacement wall switch for operating said electric motor, said replacement wall switch comprising;
a housing, a first normally open switch carried by said housing and connected to said pair of conductors;
a timer disposed within said housing;
a second switch disposed within said housing and connected in parallel with said first switch, said second switch being operable by said timer to provide a momentary closure between said pair of conductors, said timer comprising a timer input;
a sensor disposed to detect that said garage door is open or closed, said sensor coupled to said timer input;
said sensor and said timer cooperatively operable such that when said sensor detects that said garage door is closed, said timer is reset and disabled, and operable such that when said sensor detects that said garage door is open, said timer initiates timing a predetermined time period, said timer operating said second switch at the end of said predetermined time period; and
said sensor comprises a transmitter, said transmitter being operable to generate a door open signal when said garage door is open; and
said housing comprising a receiver responsive to said door open signal to initiate operation of said timer.

Abstract
A security kit is provided for automatic closing of a garage door after a predetermined time of garage door being open. The security kit comprises a replacement wall switch for operating the garage door operating mechanism. The replacement wall switch comprises a timer module and a sensor disposed to detect that the garage door is open or closed. The sensor is coupled to a timer input. The sensor and the timer cooperatively operate such that when the sensor detects that the garage door is closed, the timer is reset and disabled, and further cooperatively operate such that when the sensor detects that the garage door is open, the timer initiates timing a predetermined time period. The timer operates a switch at end of the predetermined time period to cause the garage door mechanism to close the garage door.
