Abstract

A bayonet locking system for vending machines is provided to lock and unlock the machine preferably with a remotely controlled electronic operating unit. It includes at least one motor driven axially and rotationally movable bayonet with an enlarged shaped head being mounted preferably on a gasketed door and at least one receptacle receiving device disposed within the machine interior positioned for engagement by the bayonet when the door is moved to an intermediate position. The bayonet advances into the receptacle and rotates to capture it in the receptacle and then axially retracts to pull the door into the closed position wherein a gasket disposed between the door and the machine is substantially uniformly compressed and sealed around its periphery. An axially rotatable pin with fins may be used with a bracket on either the door or machine to prevent prying of the door at opposite corners.

Claims

1. A locking system for locking a movable door relative to a stationary body comprising in combination;

a bayonet locking means including a shaped end carried by either said door or stationary body;

said bayonet locking means shaped end being longitudinally translatable and rotatable;

a receiving means stationarily carried by the other of said door and stationary body adapted to receive the shaped end of said bayonet locking means;

an actuating means for advancing and retracting said bayonet locking means toward and away from said receiving means and rotating the shaped end of the bayonet locking means to capture it within and release it from the receiving means; and

said actuating means including a drive means longitudinally retracting the bayonet locking means shaped end to draw the bayonet locking means together with the receiving means and longitudinally advancing to release the bayonet locking means from the stationary receiving means.

2. A locking system as claimed in claim 1 wherein at least one of said moveable door and stationary body carries a flexible peripheral gasket and said drawing of the bayonet locking means together with the receiving means causes said gasket to compressively seal the area between the door and body.

3. A locking system as claimed in claim 1 wherein said bayonet locking means and said actuating means are carried with the door.

4. A locking system as claimed in claim 1 wherein said bayonet locking means is motor driven and said actuating means has a ramped housing cooperating with a slotted housing and pin follower carried by the bayonet locking means for providing the rotational and translational movements of the shaped end of the bayonet lock.

5. A locking system as claimed in claim 1, including:

a position sensing means for sensing the longitudinal position of said bayonet means relative to said receiving means; and

controlling means connected to said actuating means and said position sensing means for controlling the actuation of rotation of said shaped end of bayonet to capture it within and release it from said receiving means.

6. A locking system as claimed in claim 1, including:

a position sensing means for sensing the rotational position of said bayonet means; and

controlling means connected to said actuating means and said rotation position sensing means for controlling the actuation of said shaped end of bayonet to capture it within and release it from said receiving means.

7. A locking system as claimed in claim 6, wherein said controlling means is connected to an actuator current sensing means for controlling the actuation of said shaped end of bayonet to capture it within and release it from said receiving means.

8. A locking system for locking a movable door relative to a stationary body comprising in combination;

a bayonet locking means including a shaped end carried by one of said door and stationary body;

said bayonet locking means shaped end being rotatable about its translational members centerline;

a receiving means stationarily carried by the other of said door and stationary body adapted to receive the shaped end of said bayonet locking means;

an actuating means for rotating the shaped end of the bayonet locking means to capture it and release it from the receiving means;

a access control means for receiving an access control input; and

a controlling means connected to said actuating means and said access control means for controlling the actuation of said shaped end of bayonet to capture it within and release it from said receiving means.

9. A locking system as claimed in claim 8, wherein said access control means is a keypad.

10. A locking system as claimed in claim 8, wherein said access control means is a remote transmitter.

11. A locking system as claimed in claim 8, wherein said access control means is a remote transceiver.

12. A locking system as claimed in claim 8, including first sensing means for determining the relative position of said shaped end within the receiving means and second sensing means for monitoring actuation of said controlling means.

13. A locking system for locking a movable door relative to a stationary body comprising in combination;

a bayonet locking means including a shaped end carried by either said door or stationary body;

said bayonet locking means shaped end being longitudinally translatable and rotatable;

a receiving means stationarily carried by the other of said door and stationary body adapted to receive the shaped end of said bayonet locking means;

an actuating means for advancing and retracting said bayonet locking means toward and away from said receiving means and rotating the shaped end of the bayonet locking means to capture it within and release it from the receiving means;

said actuating means including a drive means longitudinally retracting the bayonet locking means shaped end to draw the bayonet locking means together with the receiving means and longitudinally advancing to release the bayonet locking means from the stationary receiving means;

and wherein one of said door and body further includes at least one rotatable pin having a finned end and the other of said door and body has a capture bracket adapted to captively hold and release said pin finned end upon rotation of the pin.

14. A locking system for locking a movable door relative to a stationary body comprising in combination;

a bayonet locking means including a shaped end carried by one of said door and stationary body;

said bayonet locking means shaped end being rotatable about its translational members centerline;

a receiving means stationarily carried by the other of said door and stationary body adapted to receive the shaped end of said bayonet locking means;

an actuating means for rotating the shaped end of the bayonet locking means to capture it and release it from the receiving means;

a current sensing means for sensing the current of said actuator; and

a controlling means connected to said actuating means and said current sensing means for controlling the actuation of said shaped end of bayonet to capture it within and release it from said receiving means.

15. A locking system for locking a movable door relative to a stationary body comprising in combination;

a bayonet locking means including a shaped end carried by one of said door and stationary body;

said bayonet locking means shaped end being rotatable about its translational members centerline;

a receiving means stationery carried by the other of said door and stationary body adapted to receive the shaped end of said bayonet locking means;

an actuating means for rotating the shaped end of the bayonet locking means to capture it and release it from the receiving means;

a position sensing means for sensing the longitudinal position of said bayonet means relative to said receiving means;

an access control means for receiving an access control input; and

a controlling means connected to said actuating means and said access control means and said position sensing means for controlling the actuation of said shaped end of bayonet to capture it within and release it from said receiving means.

16. A method of locking a movable door relative to a stationary body comprising in combination;

providing a bayonet locking means including a shaped end carried by one of said door and stationary body;

providing a receiving means stationarily carried by the other of said door and stationary body adapted to receive the shaped end of said bayonet locking means;

providing an actuating means for rotating the shaped end of the bayonet locking means to capture it and release it from the receiving means;
