Door locking device for car

Abstract

Abstract PURPOSE: To prevent the confinement of a crew in a car, by making a locking device in a releasing condition by detecting an emergency. CONSTITUTION: An urgent releasing mechanium is mounted which makes a locking device in a releasing condition by detecting emergencies, such as, the collision, overturn, etc. of a car. A releasing delay mechanism for delaying a releasing operation for a fixed time is added to said mechanium. Said locking device consists of a door relay mechanism 4, a manual switch 5 and a solenoid mechanism 6 and angent relea sing melhanism and the releasing delay mechanism have an urgent switch 3 and a relay circuit 7' and are connected to said locking device. When the detecting switch 3 is closed under a condition that an ignition switch 2 is closed in said arrangement, a coil 20 is excited and a contact 21 is closed, and a solenoid coil 15 is excited through a coil 13 and a contact 14. Thus, urgent releasing is performed. Since a circuit after a transistor 68 does not work during the time when a condenser 65 is charged, the delay time of the delay releasing mechanism is caused COPYRIGHT: (C)1979,JPO&Japio
