Abstract
Abstract A vehicle antitheft accessory readily connectable in circuit with the vehicle electrical system for the horn, running lights and the customary cigarette lighter, and utilizing the latter as a timer to temporarily deactivate an antitheft alarm but not the vehicle lights to permit the driver to exit, lock the vehicle and leave the immediate vicinity. Termination of the lighter timing cycle automatically arms the alarm device and any attempt to enter or move the vehicle is effective to energize the alarm intermittently and irregularly thereby alerting bystanders to the fact that a vandal or unauthorized person is attempting to enter or molest the vehicle.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
101 words
In a vehicle antitheft device of the type having motionresponsive switch means operable to activate the vehicle horn should an intruder enter or molest the vehicle, that improvement which comprises: relay means for utilizing the vehicle cigarette lighter as a timer to delay the supply of current to said motionresponsive switch means for a short interval to afford the operator time to exit and lock the vehicle door, and manually operable arming switch means in circuit with said cigarette lighter and with said motion-responsive switch means operable to render said cigarette lighter effective to initiate a timing cycle of the latter.
Claim 2
Dependent Claim
101 words
In a vehicle antitheft device of the type having motionresponsive switch means operable to activate the vehicle horn should an intruder enter or molest the vehicle, that improvement which comprises: relay means for utilizing the vehicle cigarette lighter as a timer to delay the supply of current to said motionresponsive switch means for a short interval to afford the operator time to exit and lock the vehicle door, and manually operable arming switch means in circuit with said cigarette lighter and with said motion-responsive switch means operable to render said cigarette lighter effective to initiate a timing cycle of the latter.
Claim 3
Dependent Claim
57 words
An antitheft device as defined in claim 1 characterized in that said manually operable arming switch means is operable between first and second positions thereof, and includes circuit means operable to disarm said antitheft device when said arming switch means is in the first position and to arm said alarm device when in the second position thereof.
Claim 4
Dependent Claim
95 words
An antitheft device as defined in claim 1 characterized in that said device is connectable in circuit with the vehicle headlights, said manually operable arming switch means being in circuit with said relay means, said relay means being operable between first and second current flow control positions and being effective in a first position thereof to control the flow of current to the vehicle horn by way of said motion-responsive switch means and being effective in a second position thereof to supply power to said vehicle headlights so long as said cigarette lighter is energized.
Claim 5
Dependent Claim
38 words
An antitheft device as defined in claim 1 characterized in the provision of circuit means including manually operable switch means for activating said horn at the option of the vehicle operator and independently of said motion-responsive switch means.
Claim 6
Dependent Claim
78 words
An antitheft device as defined in claim 1 characterized in the provision of vehicle headlight means including a manually operable switch connected in circuit with said manually operable arming means and with said cigarette lighter, said manually operable switch for said headlight means being operable when closed to supply energy to the vehicle headlights so long as said cigarette lighter is energized terminating automatically with the release of the lighter at the end of a heating cycle thereof.
