The security device comprises a steering wheel in 2 parts. When mounted the wheel rotates freely without engaging the rotatable member. The movement is controlled by a key in the centre of the device, a turn of this key engages the rotatable member. Once the wheel is disengaged any freewheeling movement of the wheel triggers an alarm switch activating also a flashing light to illuminate any intruder's face. The invention also allows a car horn to be operated via touch controls and also incorporates special lock nuts to prevent unauthorised removal of the security device. The outer part of the steering wheel is secured to the centre via two central shafts, connected to two way springs placed in the shaft. When sudden and heavy force is applied to the wheel, the impact is absorbed by the springs. <IMAGE> |
