US Patent:

59330864, Aug 3, 1999

Filed:

Dec 1, 1997

Appl. No.:

8/980727

Inventors:

Andrew Tischendorf - Milwaukee WI
Kenneth Schultz - North Prairie WI
Gary Lehman - Brookfield WI
Demos Andreou - Tucson AZ
Ari Glezer - Tucson AZ

Assignee:

Schlage Lock Company - San Francisco CA

International Classification:

H04Q 100

US Classification:

34082531

Abstract:

A keyless locking mechanism for use in a door or the like. An operator activates the system by means of a portable remote handheld controller or a remote keypad unit, which transmit coded signals to an electronically controlled, electromechanical door lock device. The electronic and electromechanical device components are configured for secure mounting within the void or hollow portions of existing door locking apparatus, such as within the hollow interior doorknob, or hollow cylindrical sleeve latch actuators, or beneath the interior rose or escutcheon plates. A sensor or receiver/antenna mounted within the outer doorknob receives and forwards the coded signals to a processor which compares them with a predetermined stored signal. If an acceptable comparison is made, the processor generates control signals for the electromechanical device, which acts solely along or about the locking axis to enable or disable the door locking assembly, according to the command initiated by the operator. When locked, the outer doorknob turns freely.

Abstract:

A keyless locking mechanism is activated by a remote unit which transmits coded signals to an electromechanical door lock device. The electromechanical device components are configured for secure mounting within the void or hollow portions of existing door locking apparatus. A sensor in the outer doorknob receives and forwards the coded signals to a processor which compares them with a predetermined stored signal. If an acceptable comparison is made, the processor generates control signals for the device, which acts solely along the locking axis to enable or disable the door locking assembly. The coded signals include two separate signals which are transmitted in segments interleaved with one another. The first signal includes an entrance code, while the second signal provides information concerning the frequency over which the next segments will be transmitted. The processor uses the second signal information to tune the receiver.
