Title:
DEVICE FOR PREVENTING LOCK-OUT BY A KEY LEFT IN IGNITION SWITCH
Document Type and Number:
WIPO Patent Application WO/1998/029284
Kind Code:
A1
Abstract:
A high-level device for preventing lock-out by a key left in an ignition on switch, realized by limiting an excess alarm from a conventional non-pulled key alarming device to a necessary extent, by developing a key lock-out prevention device through using a holding circuit, which controls the inside locking knob by fixing the same, by using a receiver relay circuit or the like for controlling the holding circuit at the same time to make it impossible to leave a key in an ignition switch for possible lock-out, or by automating a part of the holding circuit. As a transmitter mounted to a key as a key holder approaches, the device receives transmission from the transmitter to recognize a pulled-out key to control the holding circuit. Also, annexed to the device is a capacitor beep circuit for issuing beep for the recognition, or an automatic inside locking knob pushing circuit for partial automation.
