Abstract
An anti-theft arrangement for a motor vehicle comprising an electrically operable device associated with a system or component essential to operation of the engine of the vehicle and which in a first state permits normal operation of the associated system or component and which in a second state does not, and wherein the supply of electrical current to said device is controlled by combination or key-operated switching means and in which the arrangement is such that said electrically operable device is automatically placed in its state preventing normal operation of the engine upon disconnection of the device from a supply of electrical current.
Claims8
An anti-theft arrangement for a motor vehicle comprising
- an electrically operable engine disabling device associated with a system or component essential to operation of the engine of the vehicle and which in a first state permits normal operation of the associated system or component and which in a second state does not;
- means for connecting a supply of electrical current to said device, said supply being controlled by combination switching means and in which the arrangement is such that said electrically operable engine disabling device is automatically placed in its state preventing normal operation of the engine upon disconnection of the device from said supply of electrical current;
- and
- said combination switching means comprising a plurality of multi-position rotary switches series connected, each having a respective manually operable outer operating knob, for each said switch, scale means and marker index means for each said knob whereby the rotary position of each said knob can be identified.
An anti-theft arrangement for a motor vehicle comprising
- an electrically operable engine disabling device associated with a system or component essential to operation of the engine of the vehicle and which in a first state permits normal operation of the associated system or component and which in a second state does not;
- means for connecting supply of electrical current to said device, said supply being controlled by combination or key-operated switching means and in which the arrangement is such that said electrically operable engine disabling device is automatically placed in its state preventing normal operation of the engine upon disconnection of the device from said supply of electrical current;
- said switching means being housed within a casing having a removable lid;
- locking means being provided for locking said lid against opening, said locking means including abutment means within said casing and detent means within said casing movable between a locking position engaging said abutment means to prevent opening of said lid, and an unlocking position in which it is disengaged from said abutment means to allow the lid to be opened;
- and
- including frangible conductor means connected in circuit with said switching means, means mounting said frangible conductor means on one of said lid and said casing in such relating to a member carried by the other of said lid and said casing, that said frangible conductor means is likely to be broken, to disable said electrically operable device, if the lid is forced open with said detent means in said locked position.
