Abstract

Abstract An ignition and hooklock assembly for an automotive vehicle includes a support mounted under the hood and carrying an axially slidable bolt movable between two positions for locking and unlocking the hood. A solenoid having a spring loaded plunger engages the bolt in each position to prevent axial movement of the bolt. A remotely located switch is connected in series with a power supply and the solenoid which when energized releases the bolt which can then be moved axially by an attached wire terminating in an operating handle. A pushbutton switch disposed in the support is connected in the ignition circuit for closing this circuit when the bolt is retracted. Either one or both of the remotely located switch and operating handle may be provided with key operated locks to prevent unauthorized operation.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 232 words
An ignition and hood lock apparatus comprising: a support mountable in the compartment closed by said hood, said support having a longitudinally extending passage therethrough, said support having a chamber which is open to said passage. a bolt carried by said support which is axially slidable between two positions in said passage for selectively and alternately locking and unlocking said hood; a solenoid means adjacent said support having a spring loaded plunger arranged to engage and lock said bolt in each of said two positions to prevent axial slidable movement thereof; a power supply a switching means remotely located from said solenoid means and adapted to connect said power supply to said solenoid means to energize the same to retract said plunger for disengaging and unlocking said bolt; means for manually moving said bolt between said two positions selectively when said solenoid is energized upon closing said switch means to retract said plunger; a micro-switch carried by said support in said chamber and having a spring biased button protruding in said passage for retraction by said bolt when said plunger is engaged in a first position whereby said switch is closed and when said plunger is engaged in the other position, said button extends into said passage thereby opening said switch; an ignition switch connected to series circuit with said power supply and only when said button is retracted by said bolt.
Claim 2
Dependent Claim 232 words
An ignition and hood lock apparatus comprising: a support mountable in the compartment closed by said hood, said support having a longitudinally extending passage therethrough, said support having a chamber which is open to said passage. a bolt carried by said support which is axially slidable between two positions in said passage for selectively and alternately locking and unlocking said hood; a solenoid means adjacent said support having a spring loaded plunger arranged to engage and lock said bolt in each of said two positions to prevent axial slidable movement thereof; a power supply a switching means remotely located from said solenoid means and adapted to connect said power supply to said solenoid means to energize the same to retract said plunger for disengaging and unlocking said bolt; means for manually moving said bolt between said two positions selectively when said solenoid is energized upon closing said switch means to retract said plunger; a micro-switch carried by said support in said chamber and having a spring biased button protruding in said passage for retraction by said bolt when said plunger is engaged in a first position whereby said switch is closed and when said plunger is engaged in the other position, said button extends into said passage thereby opening said switch; an ignition switch connected to series circuit with said power supply and only when said button is retracted by said bolt.
Claim 3
Dependent Claim 48 words
An apparatus as defined in claim 1, wherein the means for moving said bolt axially comprises a wire connected at one end to said bolt; a mounting bracket mounted remotely from said apparatus; and a handle connected to the other end of said wire at said mounting bracket.
Claim 4
Dependent Claim 27 words
An apparatus as defined in claim 2, further comprising an armored sleeve surrounding said wire and connected at opposite ends to said support and said mounting bracket.
Claim 5
Dependent Claim 31 words
An apparatus as defined in claim 2, further comprising key operated lock means for locking said handle at said bracket to prevent inadvertent or unauthorized operation of said wire and bolt.
