JPH01239273A - Remotely controlled lighting lock - Google Patents

Abstract

PURPOSE:To facilitate locking and unlocking in a dark place by mounting a switch which acts sensing an ultrasonic wave, and a light emitting unit which emits light by an electric current passing through. CONSTITUTION:A passkey set mounts a fellow key 7 to an ultrasonic transmitter 6 emitting an ultrasonic wave of specific frequency, approaching a lock 1. Next the ultrasonic wave, when it is emitted toward an ultrasonic switch 5, actuates it, and a light emitting diode 3 is turned on allowing an electric current to flow. Then inserting the fellow key 7 to a key hole 2, locking or unlocking is performed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a lock for attaching to a door and a similar lock.

[Prior Art and Problems to be Solved by the Invention] Conventionally, locks equipped with a light emitting body have been equipped with a switch on an operating part such as a lever, knob, or push button to connect the power source of the light emitting body. Since the light-emitting body cannot be made to emit light unless you touch and operate it directly, it is difficult to check the position of the lock from a distance in a dark place.

In addition, it is often difficult to tell whether a key is compatible with a lock until the key is actually inserted into the keyhole.

To enable the user to confirm the position of a keyhole from a distance in a dark place and to know that the key fits the keyhole before inserting the key into the keyhole.

[Means to solve the problem] A luminous body that emits light when a current is passed through it is attached near the keyhole of the lock, and a switch that is activated in response to ultrasonic waves of a specific frequency is placed between the luminous body and the power source. Connect the switch, attach an ultrasonic transmitter that emits ultrasonic waves at the frequency that activates the switch to a key that matches the lock, and when the ultrasonic transmitter of the compatible key receives the ultrasonic wave, the light emitter will light up. A current flows and the light emitter emits light.

[Operations and Effects] When you approach the lock of the present invention with a matching key and emit ultrasonic waves from the ultrasonic transmitter attached to the key, your body will emit light from the transmitter attached near the keyhole, allowing you to use it in dark places. Not only can you check the keyhole position: 11 from a distance, you can also know whether the key is suitable or not before inserting it into the keyhole.

[Example] Fig. 1 is a configuration diagram showing an example of the implementation of the remote control lighting lock of the present invention.A light emitting diode 3 is attached around the outside of the keyhole 2 of the lock l, and a dry battery 4 is connected via an ultrasonic switch 5. and connect it to light emitting diode 3.

The ultrasonic switch 5 is adjusted to connect the contacts only in response to ultrasonic waves of a specific frequency.

Attach the duplicate key 7 to the ultrasonic transmitter hb that emits ultrasonic waves at that frequency, approach the lock l with this, and when the ultrasonic wave is emitted, the ultrasonic switch 5 is activated and the light emitting diode 3 is activated.
Current flows through the lamp and lights it up.

In a hotel where a large number of hotel guest room doors are lined up facing the hallway, the remote control lighting lock of the present invention is attached to each door and the sensitive frequency is set to a different frequency. If you walk down the hallway with the key to your room and try to turn on the lock using the ultrasonic transmitter attached to the key, only the lock in your own room will light up, so you won't be in the wrong room.

Furthermore, by attaching this lock to a car door, the car owner can definitely identify his car if it is parked in a dark place at night, and can also accurately identify the location of the keyhole before touching the table. You can.
