DESCRIPTION:
BRIEF SUMMARY
The invention relates to an immobilising device on a wheeled vehicle.
BACKGROUND OF THE INVENTION
Wheel clamps are known in various forms. These may be used by third parties to immobilise vehicles which are parked where they should not be or increasingly are being used by companies and private individuals to prevent theft of vehicles. Trailers and horse boxes are particularly prone to theft and may be locked with a wheel clamp. However, the user must remember to take the wheel clamp with him in order to be able to use it. Also, if the wheel clamp is not used, it may itself be stolen.
SUMMARY OF THE INVENTION
According to the invention there is provided an immobilising device on a wheeled vehicle, the immobilising device being connected to the vehicle by a connection and being arranged to be secured to or about a wheel to prevent rotation or complete rotation of the wheel and thereby immobilise the vehicle.
If the immobilising device is connected to the vehicle, the user cannot forget to take it with him and the device cannot be stolen when not in use.
The immobilising device is preferably a wheel clamp.
The immobilising device is preferably retained outside the vehicle when not in use and may be covered by a cover or in a housing when not in use.
The connection may be connected to any suitable part of the vehicle and in a preferred embodiment is connected to a chassis of the vehicle. This provides a strong connection which is relatively difficult to access.
The connection preferably consists of at least one rigid element. In this way the connection can be stronger and resist cutting better. The connection may comprise two or three rigid elements which may be connected pivotally and/or slidably. This construction lends strength to the connection.
The connection may include a rod which is slidable in relation to the wheel. In this way, the device may be slid towards and away from the wheel for fitting and removal. The rod may be slidable in any suitable direction. In one embodiment the rod is slidable axially in a direction substantially parallel to the wheel axis. Thus the device can be slid inwardly and outwardly. In another embodiment the rod is slidable axially backwards and forwards in relation to the vehicle. In that case the device is preferably stored forwards of the wheel when not in use. In that way dirt, water and other water driven backwards by the wheel will not be driven onto the device. Which embodiment is chosen may depend upon the available space around the wheel. Preferably, the rod is slidable in at least one bush (alkla bushing) and there are preferably two bushes. Where the rod is slidable axially in a direction substantially parallel to the wheel axis the two bushes may be symmetrically spaced about the long axis of the vehicle.
The connection may permit movement of the device in the forwards or backwards direction of the vehicle. This movement may be permitted in any suitable manner and conveniently the connection permits rotation of the device. The rotation may be about an axis parallel to the wheel axis. In a preferred embodiment, the connection includes a rod which is rotatable about its own axis. The rod may be rotatable in at least one bush and preferably there are two bushes. The rod may be mounted to lie parallel to the wheel axis and in that case the two bushes may be symmetrically spaced about the long axis of the vehicle. The rod is preferably the same rod which is slidable axially. The or each part of the rod which contacts the or each bush may be round but preferably is of polygonal transverse cross-section, preferably of square transverse cross-section. This ensures that the rod does not jam or become difficult to move in the way that a round rod in a round bush might do, in particular where the connection is outside the vehicle and therefore liable to collect road debris.
The rod is preferably connected to the device by a bar transverse to the rod. The device may be mounted to be able to pivot in relation to the rod. Thus, the orientation of the device can be change
