Abstract
A vehicle entry control system utilizing electrically operated deadbolts, actuated in response to the code signal of a remote control transmitter, which provide positive protection against the various mechanical techniques used to defeat conventional vehicle door locks. The system uses electrical linear actuators to position the deadbolts, a door interlocked switching circuit, with the deadbolts positioned to allow the mechanical release of the deadbolts in the event of a malfunction, but to accomplish this requires the facilities of a service shop and an amount of time and labor that would be prohibitive for a thief.
Claims13
A vehicle keyless deadbolt locking system for vehicle doors, trunk and hood, said system comprising:
- (a) a portable digital code generating transmitter with a companion receiver having lock and unlock signal outputs mounted in the vehicle;
- (b) a circuit responsive to the outputs of the said receiver that drive electrical linear actuators to place deadbolts into lock and unlock positions, said circuit interlocked with the vehicle doors to prevent placing the deadbolts into the lock position unless all doors are closed;
- (c) deadbolts and companion strike plates mounted in the vehicle in positions that permit ready physical access in a service shop to said deadbolts to allow said deadbolts release from lock position to unlock position in the event of system electrical failure, but access would require a prohibitive amount of time and labor for a thief;
- (d) means for adjusting the degree of difficulty of the actions required for deadbolt access;
- and
- (e) means for locating the deadbolt position to obtain deadbolt access by drilling through, or otherwise removing, one or more barriers at said deadbolt position.
A vehicle keyless deadbolt locking system for vehicle doors, trunk and hood comprising:
- (a) a portable digital code generating transmitter;
- (b) a companion receiver with lock and unlock signal outputs mounted in a vehicle having a plurality of doors, rear wheel wells, a trunk and a hood;
- (c) at least one deadbolt for each of said doors connected to an electrical linear actuator mounted in said vehicle, said deadbolts located in the bottom of each door to permit ready physical access to said deadbolts in a service shop to allow said deadbolts release from lock to unlock position in the event of system electrical failure, but said release would require the removal of one or more barriers and thus a prohibitive amount of time and labor for a thief to accomplish;
- (d) an electrical circuit in said vehicle responsive to said signal outputs of said receiver and said electrical circuit drives said linear actuators to move said deadbolts into locked and unlocked positions;
- (e) said vehicle having door openings having a bottom panel, a strike plate secured to the bottom panel of each of the door openings of said vehicle that mates with the companion deadbolt in the locked position;
- and
- (f) said bottom panel having an outer surface and means on the outer surfaces of said bottom panels of the said vehicle at locations under each vehicle door for identifying where a barrier is to be removed to access the deadbolt of that door in order to effect the said release in the event of system electrical failure.
