Abstract

Device for simultaneously locking or releasing a plurality of doors of a vehicle. Each door has an electrical latch and each electromagnet for withdrawing the bolt of the latch is connected to a source of voltage through a common switch. The latter is connected in series with the electromagnets and actuatable by a first coil which is connected to the source through at least one switch in series for locking the doors. The common switch is also actuatable by a second coil connected to the source through at least one switch in series for releasing the doors.

Claims

1. A device for simultaneously controlling a plurality of doors of a vehicle for the purpose of sElectively locking and releasing the doors, comprising for each door an electrical latch which comprises a withdrawable bolt, an electromagnet having a moving part connected to the bolt for withdrawing the bolt when the electromagnet is energized ;

a source of voltage having terminals ;

a common switch connected in series with each electromagnet for connecting each electromagnet to said terminals ;

a first coil for actuating the common switch ;

at least one switch for locking the doors connected in series with the first coil for connecting the first coil to said terminals ;

a second coil for actuating the common switch ;

at least one switch for releasing the doors connected in series with the second coil for connecting the second coil to said terminals, said device further comprising a moving part of a latch on one of the doors associated with the switch for locking the doors, said moving part of the latch being movable from outside the door by means of a key which causes, when the key is rotated in a first direction, the mechanical releasing of the door by the moving part of the latch and, when the key is rotated in the opposite direction, the closing of the switch for locking the doors by the moving part of the latch.

2. A device as claimed in claim 1, wherein said switch for releasing the doors is associated with said moving part of the latch, the switch for releasing the doors being closed by an initial movement of the moving part of the latch in a direction for mechanically opening the door before withdrawing the bolt of the latch.
