Abstract

A vehicle locking system for a secure delivery van having a driver'"'"'s cabin and a cargo space with respective doors has an electrically operable locking system including a selection member in the driver'"'"'s cab, and a respective key operated switch at the or each cargo space door. The system immobilizes the vehicle except in one position of the selection member, and all the doors are locked when the selected member is positioned to allow the vehicle to be driven. Furthermore where the vehicle has a plurality of doors to the cargo space, only a selected such door, as selected by the selection member, may be opened. The system is designed to minimize opportunistic theft which might otherwise be permitted by the vehicle driver neglecting to lock doors.

Claims

1. A vehicle locking system for a vehicle having a driver'"'"'s cab and at least one door remote from the driver'"'"'s cab, a lock for said door, a control facility for operating said lock automatically, said system including immobilizing means for immobilizing the vehicle, and wherein said control facility controls said immobilizing means, said control facility including a control member located in the driver'"'"'s cab and movable to any of a plurality of positions, in one of which positions the control facility selects said door and immobilizes the vehicle, and in another of which positions the vehicle is no longer immobilized by said immobilizing means but said door is necessarily locked, said control facility including a key-switch located adjacent said door remote from the driver'"'"'s cab, said key switch including an operating member providing a keyhole exposed adjacent said door for receiving a key whereby the key switch may be operated, said control facility being arranged to open said door only if said control member is in a position to immobilize the vehicle and select said door and said key switch is operated.

2. A vehicle locking system according to claim 1 wherein the vehicle has a plurality of doors, a respective lock for each of said doors, said locks being operable by said control facility, said control facility being such that different said doors are selected in different positions of the control member and that only a said door which is selected by the control member at any time maybe unlocked while any door not so selected may not be unlocked, even when the vehicle is immobilized.

3. The vehicle locking system of claim 2 including, for each of said doors, means for sensing when said door is closed, and wherein said control facility is arranged to cause the respective said lock to be placed in its door-locking state when the respective door is closed.

4. A vehicle locking system for a vehicle having at least one door, the system including a lock for said door, a control facility for operating said lock automatically, said system also including immobilizing means for immobilizing the vehicle, and wherein said control facility controls said immobilizing means and is so arranged that when said control facility is in its state in which said door is unlocked, said immobilizing means is in a condition immobilizing the vehicle, and when the control facility is in its state in which the vehicle is no longer immobilized by said immobilizing means said door is necessarily locked, and wherein the vehicle further includes a driver'"'"'s cab and said at least one door being remote from the driver'"'"'s cab and wherein said control facility includes a control member located in the driver'"'"'s cab, a key-switch located adjacent said door remote from the driver'"'"'s cab, said key switch including an operating member incorporated in the associated lock providing a keyhole exposed adjacent said door for receiving a key whereby the key-switch may be operated, said control facility being arranged to open said door only if said control member is in a position to immobilize the vehicle and select said door and said key-switch is operated.

5. The vehicle locking system of claim 4 including means for sensing when said door is closed, and wherein said control facility is arranged to cause said automatically operable lock to be placed in its door-locking state when the respective door is closed.

6. The vehicle locking system of claim 5 wherein said control facility includes time delay means whereby, when said door is closed, said lock is placed in its door-locking position only after a predetermined delay.
