An electronic lock system is provided with an audible entry monitor for confirmation of entry of an input code and a mischief preventive circuit for disabling the audible entry monitor for a given period of time in response to an excessive number of inaccurate code input attempts. The audio signal generator is associated with a pushbutton input unit having a plurality of push buttons. The audio signal generator is adapted to produce an audible signal whenever an input code is entered through the input unit. The audible signal generator is also associated with a comparator for comparing the input code and a permanent code. The comparator is adapted to allow the system to change a voluntary code and operates the audible signal generator to produce another audible signal for a predetermined period while the system is capable of accepting entry of the new voluntary code to be preset.

A pressure control device with a fluid discharge prevention mechanism such that operation is reliable, size is small, weight is light, and cost is low. The pressure control device according to the present invention comprises a novel valve body housing a weight and a fluid discharge prevention valve together, a vessel body with a tank-communicating port, and a lid with an atmosphere-communicating port. The top circumferential surface of the valve body serves also as a vacuum pressure regulation valve in cooperation with the vessel body.

A stopper is provided on the inner wire of a Bowden cable type arrangement. The stopper allows the wire to be pulled in a first axial direction to operate one of two latch mechanisms and engages a shoulder defined in the second latch mechanism when driven in a second axial direction to produce a reaction which causes the tubular housing disposed about the wire between the second latch mechanism and a single handled actuating mechanism, to flex and pull a lever of the second latch mechanism for operating same, whereby a single lever can be used to selectively operate two different mechanisms.

A locking means for a trunk in an automobile is disclosed which can be unlocked by the rotation of a key inserted in a key cylinder of the trunk and which comprises a first switch provided at a proper location in the room of the automobile to open and close a D.C. circuit including an actuator means for unlocking the locking means. A second switch which is usually closed is provided in said D.C. circuit in such a way as to be opened by the rotation of said key inserted in the key cylinder of the trunk in a direction contrary to that for unlocking the locking means, thereby it becomes possible for a proprietor of the automobile who stands outside the automobile near the trunk to actuate the second switch so as to prevent the opening of the trunk by any other person against the will of the proprietor.

A push-pull cable arrangement for selectively transmitting longitudinal motion to two separate destinations has an inner wire having a front end, a rear end and an intermediate node between the front and the rear ends. The inner wire is enclosed with a first outer casing between the front end and the intermediate node, and with a second outer casing between the intermediate node and the rear end. Front and rear ends of the first outer casing are held stationary. A front end of the second outer casing facing the intermediate node of the inner wire is movable, and a rear end of the second outer casing facing the rear end of the inner wire is held stationary. When the front end of the inner wire is pulled, a longitudinal motion of the inner wire is transmitted to the rear end of the inner wire, by which a first receiving unit is moved. When the front end of the inner wire is pushed, the intermediate node of the inner wire pushes the front end of the second outer casing, by which a second receiving unit is moved.

The present invention relates to a hood locking apparatus for motor vehicles, and more particularly to a hood locking apparatus which is adapted to overcome any tendency for a remote control cable to disengage from a base plate of the locking mechanism. The locking apparatus uniquely comprises a reinforcing plate defined at the reverse side of a base plate to straddle mounting end portions defined at opposite ends of the base plate for attachment to the vehicle body and a cable disengagement preventive piece defined at and projected from the reinforcing plate to extend in the direction of a notch formed through the base plate. The reinforcing plate has its one end welded to the mounting end portions in such a manner that a predetermined clearance can be formed between the other end and one of the mounting end portions of the base plate. The cable disengagement preventive piece terminates short of an opening of a notch formed through the base plate with the reinforcing plate having its one end welded to the base plate, and closes the opening mentioned above when the other mounting end portion of the base plate is attached to the vehicle's body by means of a bolt together with the other end of the reinforcing plate.

A door locking system for an automotive vehicle including an anti-theft automatic door locking apparatus by which the door can automatically be locked a fixed time period after the door has been closed in the case where an ignition switch is open and the ignition switch is left at the steering-lock position. The door locking system according to the present invention comprises an ignition switch for detecting the state in which the engine is not operating, a door-close switch for detecting the state where the vehicle doors are closed, a timer for delaying the automatic locking of the doors for a fixed time period, and an AND gate, in addition to the conventional door locking system.

An engine starter circuit for an automotive vehicle provided with an automatic transmission such that an engine can be started only when the gear selector lever is in the park or neutral position, in particular, only when the gear selector lever is securely shifted into the park position. The engine starter circuit according to the present invention comprises a redundant park-position detection switch in addition to an engine-starter switch and an inhibitor switch including a park-position detection switch and a neutral-position detection switch, so that the pseudo-parking position caused by a mechanical play in a linkage mechanism can be reduced, with more reliable detection of the park position. The redundant park-position detection switch is a pin-actuated or a body-actuated selector microswitch positioned with respect to the gear selector lever of the automatic transmission and so constructed as to reduce the mechanical play inherent in the detection of park-position.

An alarm system for an automatic transmission includes an alarm device and two or three control switches in a serial connection. One switch closes when the transmission selector lever is not in park position; the second switch closes when a condition preparatory to leaving the vehicle, such as door opening, is detected. The third, optional switch closes when an emergency brake is not securely engaged. Thus, an alarm is generated when the driver prepares to leave the vehicle with the transmission selector lever not in the park position. Redundant switches are disclosed for the first and second switches. Also, a holding relay is disclosed which maintains the alarm until the automatic transmission selector lever is shifted into the park position, by closing a shunt across the second switch whenever the alarm is produced.
