Definitions

  • This invention relates to locking arrangements for goods vehicles.
  • the present invention provides a locking arrangement which does not have these disadvantages.
  • the invention comprises a locking arrangement for goods vehicles comprising a pneumatically actuated bolt cooperating with an apertured member to secure the vehicle closed, said bolt being pneumatically retractable to unlock the vehicle by a secure valve and powered from the vehicle's pressure air supply.
  • US Patents Nos. 3601453 and 3624761 relate to trailer locking arrangements which are similarly pneumatically actuable only when the tractor is attached.
  • a disadvantage of those arrangements is that the pneumatic unlocking is relatively, easy to achieve when the trailer is disconnected (or even when it is connected, but unattended, so that it is surreptiliously disconnectible) by attaching a pressure air supply to the disconnected air hose connections of the trailer. Perhaps because these arrangements are easily defeated, however, they have not apparently found favour among owners of goods vehicle fleets.
  • Said secure valve may be operated by a security key and may be electrically operated so that a lock can be remotely situated from the valve, for example in the driver's cab or at a convenient location close to the vehicle door or shutter.
  • Said bolt may be biassed towards the locking position, and may be retractable against the bias by said apertured member for automatic locking on closure.
  • Said apertured member and bolt may have a camming action, after the fashion of a Yale lock.
  • Said bolt may be held retracted from said aperture member on actuation for a short time interval - for example by a dashpot arrangement - before automatically returning to the locking position.
  • the time interval may be selected to be, say, thirty seconds, to give the driver time to reach and open the door.
  • the bolt and associated actuating means and said apertured member - which may be a lug fixed to the lower edge of a roller shutter - when in the closed position are desirably securely concealed. They may of course be mounted internally of the vehicle in suitable cases, but should be covered or boxed into a suitably secure location if mounted externally.
  • the locking arrangement illustrated in the Figure comprises a pneumatically actuated bolt 11 cooperating with an apertured lug 12 fastened to the inside of the lower edge of a roller shutter rear door 13 of the van.
  • the bolt 11, lug 12 and the pneumatic actuating cylinder 14 are concealed in a hardened box arrangement 15.
  • the bolt 11 is biassed by a spring 16 to the locked position where it engages the apertured lug.
  • the lug 12 and bolt 11 have a camming action however, so that on closure of the door the bolt will move back on being contacted by the lug after the fashion of a Yale lock.
  • Air from the vehicle's pressure air supply 17 is admitted to the cylinder 14 to cause the bolt 11 to retract by a secure valve 18 which has an electric actuator 19 to which current is supplied from a remote lock 21 operated preferably by a security key.
  • the lock 21 can be located in the driver's cab or at a convenient position at the rear of the vehicle.
  • Either valve 18 comprises a dashpot arrangement, or the system is arranged electrically by a timer, to maintain pressure to the cylinder 14 only for a short time interval after actuation so that the bolt automatically returns to the locked position - the time interval will of course be sufficient to allow the driver to reach and open the door.
  • valve 18 is securely contained like the bolt 11, lug 12 and cylinder 14, and located close to these members so as to avoid the possibility of unauthorised access to the air supply line between valve 18 and cylinder 14.
  • the arrangement described with reference to the drawing is by way of example only, many modifications being possible while retaining the advantages of the invention.
  • the cylinder 14 could be double acting and the valve 18 controlled to engage the bolt 11 automatically on closure, for example by a proximity switch actuated by the bottom of the door.
  • the arrangement may also be mounted at the top of the door rather than at the lower edge as illustrated, rendering it less accessible to those intending unauthorised entry.
  • the arrangement can be coupled to other security systems, for example to a security alarm so that an alarm is raised if the valve 18 is actuated without the lock 21 being properly operated.
  • the arrangement is secure against the unauthorised use of pressure air from an external source to release the lock.
