Abstract

The remote controlled security device which can be controlled by a radiant energy transmitter so as to lock or unlock it, is mounted on the inside wall of a container and has a locking bar which is engageable with a locking plate that has an aligned opening for receiving locking bar of the security device. The locking bar can be moved by stepper motor from the locked to the unlocked position in response to actuation of the remote control transmitter to allow the door of the container to be locked or unlocked. There is also provided a key with an opening which can be inserted through the wall of the container to engage a projection which has the same shape as the opening in the key to allow the lock to be manually locked or unlocked.

Claims

1. A remotely controlled security device comprising:

a container with a movable door, said security device connected to said container and provided with a movable locking bar which is engageable with said door to selectively lock or unlock the doors;

a radiant energy transmitter with lock and unlock switches;

a radiant energy receiver connected to said security device to receive signals from said energy transmitter;

a stepper motor mounted in said security device and connected to receive output signals from said receiver;

an output shaft of said stepper motor connected to said locking bar to move the output shaft between the locked and unlocked position;

a unique extension formed on said output shaft; and

a key with a mating unique opening which can receive said unique extension to allow said output shaft to rotate between the locked and unlocked positions.

2. The remote controlled security device according to claim 1 wherein said security device is attached to an inner wall of said container, and an opening formed through said inner wall through which said key can be extended to engage said output shaft.

3. The remote controlled security device according to claim 2 further comprising:

a removable cover plate attached over said opening.

4. A security device for a container with a movable door, the device comprising:

a stepper motor with an output shaft connected to said container;

a cam plate mounted on said output shaft and formed with an arcuate slot;

a locking bar mounted for longitudinal movement coupled to said arcuate slot in said cam plate, said locking bar engageable with said door and longitudinally movable between locked and unlocked positions;

a radiant energy receiver connected to said stepping motor to actuate it to the locked and unlocked positions; and

a radiant energy transmitter with lock and unlock switches for energizing said radiant energy receiver.

5. The security device according to claim 4 further comprising:

a key with a unique opening wherein said output shaft is formed with a unique projection which is receivable within said unique opening so that said key can rotate said output shaft.
