Abstract

The present invention is an automatic garage door operator with a two button portable controller enabling a secure mode and control of a load remote from the door operator. In accordance with the normal operation of the secure button, actuation when the garage door is closed toggles a secure mode between secure and non-secure states. In the secure state the automatic garage door operator does not move the door upon receipt of a door signal. To open the door when in the secure state the operator must first press the secure button to enter the non-secure state and then press the door button to open the door. The secure button has a secondary function when the garage door is open and the secure state is prohibited. Actuation of the secure button when the door is open toggles the state of a load remote from the automatic garage door operator between an on state and an off state. This control is achieved via a signal modulated on the electric power main.

Claims

1. An automatic garage door operator for controlling a remote load and the position of a garage door comprising:

a radio frequency receiver for generating a door signal upon receipt of a first encoded radio frequency signal and a secure signal upon receipt of a second encoded radio frequency signal;

a door actuator connected to the garage door for operating the garage door; and

a controller means connected to said radio frequency receiver, said door actuator and the remote load, said controller means having a secure mode, a non-secure mode, a load on mode and a load off mode for

controlling said door actuator to operate the garage door upon receipt of said door signal when said controller means is in said non-secure ode,

inhibiting said door actuator to prevent operation of the garage door upon receipt of said door signal when said controller means is in said secure mode,

toggling between said secure mode and said non-secure mode upon receipt of said secure signal when the garage door is closed,

turning the remote load ON upon receipt of said secure signal when the garage door is not closed and said controller means is in said load off mode, and

turning the remote load OFF upon receipt of said secure signal when the garage door is not closed and said controller means is in said load on mode.

2. The automatic garage door operator as claimed in claim 1 for further controlling a second remote load, wherein:

said controller means is further connected to the second remote load and further includes means for

turning the second load ON upon receipt of said door signal when said controller means is in said non-secure mode, and

turning the second load OFF a predetermined time after movement of the garage door has stopped.

3. The automatic garage door operator as claimed in claim 1 for further controlling a second remote load, further comprising:

a door position sensing means connected to the garage door for indicating whether the garage door is fully closed;

said controller means is further connected to said door position sensing means and the second remote load and further includes means for

turning the second load ON when said door position sensing means indicates the garage door is leaving fully closed and said controller means is in said non-secure mode, and

turning the second load OFF when said door position sensing means indicates the garage door is fully closed.

4. The automatic garage door operator as claimed in claim 1 for further controlling a second remote load and a third remote load, further comprising:

a door position sensing means connected to the garage door for indicating whether the garage door is fully closed;

said controller means is further connected to said door position sensing means, the second remote load and the third remote load, and further includes means for

turning the second load ON upon receipt of said door signal when said controller means is in said non-secure mode,

turning the second load OFF a predetermined time after movement of the garage door has stopped,

turning the third load ON when said door position sensing means indicates the garage door is leaving fully closed and said controlled means is in said non-secure mode, and

turning the third load OFF when said door position sensing means indicates the garage door is fully closed.

5. The garage door operator a claimed in claim 1, further comprising:

a portable radio frequency transmitter having a door push button and a secure push button, said portable radio frequency transmitter for transmitting said first encoded radio frequency signal upon actuation of said door push button and said second encoded radio frequency signal upon actuation of said secure push button.

6. An automatic garage door operator for controlling a remote load and the position of a garage door comprising:

a radio frequency receiver for generating a door signal upon receipt of a first encoded radio frequency signal and a secure signal upon receipt of a second encoded radio frequency signal;

a door actuator connected to the garage door for operating the garage door;

a manual mode switch operable between a load only mode and a load/secure mode;

a controller means connected to said radio frequency receiver, said door actuator, said manual mode switch, and the remote load, said controller means having a secure mode, a non-secure mode, a load on mode and a load off mode for

controlling said door actuator to operate the garage door upon receipt of said door signal when said controller means is in said non-secure mode,

inhibiting said door actuator to prevent operation of the garage door upon receipt of said door signal when said controller means is in said secure mode,

toggling between said secure mode and said non-secure mode upon receipt of said secure signal when the garage door is closed and said manual mode switch is in the load/secure mode,

turning the remote load ON upon receipt of said secure signal when the garage door is not closed, said manual mode switch is in said load/secure mode and said controller means is in said load off mode,

turning the remote load OFF upon receipt of said secure signal when the garage door is not closed, said manual mode switch is in said load/secure mode and said controller means is in said load on mode.

7. The automatic garage door operator as claimed in claim 6 for further controlling a second remote load, wherein:

said controller means is further connected to the second remote load and further includes means for

turning the second load ON upon receipt of said door signal when said controller means is in said non-secure mode,

turning the second load OFF a predetermined time after movement of the garage door has stopped.

8. The automatic garage door operator as claimed in claim 6 for further controlling a second remote load, further comprising:

a door position sensing means connected to the garage door for indicating whether the garage door is fully closed;

said controller means is further connected to said door position sensing means and the second remote load and further includes means for

turning the second load ON when said door position sensing means indicates the garage door is leaving fully closed and said controller means is in said non-secure mode, and

turning the second load OFF when said door position sensing means indicates the garage door is fully closed.

9. The automatic garage door operator as claimed in claim 6 for further controlling a second remote load and a third remote load, further comprising:

a door position sensing means connected to the garage door for indicating whether the garage door is fully closed;

said controller means is further connected to said door position sensing means, the second remote load and the third remote load, and further included means for

turning the second load ON upon receipt of said door signal when said controller means is in said non-secure mode,

turning the second load OFF a predetermined time after movement of the garage door has stopped,

turning the third load ON when said door position sensing means indicates the garage door is leaving fully closed and said controller means is in said non-secure mode, and

turning the third load OFF when said door position sensing means indicates the garage door is fully closed.

10. The garage door operator as claimed in claim 6, further comprising:

a portable radio frequency transmitter having a door push button and a secure push button, said portable radio frequency transmitter for transmitting said first encoded radio frequency signal upon actuation of said door push button and said second encoded radio frequency signal upon actuation of said secure push button.
