JPH0973802A - Earthquake-sensitive flashlight - Google Patents

Abstract

PROBLEM TO BE SOLVED: To light a flashlight via the detection of an earthquake and take out the flashlight for use by applying the constitution that two upper and lower conductive plates having the capability of being pressed to and coming in contact with each other with a spring are arranged on the upper part of a case containing a cell. SOLUTION: A circular hole 2a is drilled through a turning plate made of a rectangular synthetic resin plate, and a glass bulb body 2 is placed in the hole 2a in a stationary state. Also, a conductive plate 5 made of a metallic plate is secured to the lower surface of the plate 2 around the hole 2a, and the upper end of a coil spring 7 is fitted to the lower surface of a conductive plate 6 positioned below the plate 5. In this case, when the body 3 is placed on the hole 2a, the lower part of the body 3 comes to be positioned below the hole 2a and pushes down the plate 6. As a result, the plates 5 and 6 fall in a non-contact state. When an earthquake takes place, however, the body 3 jumps up to part from the hole 2a, and the plate 2 turns. Consequently, the plates 5 and 6 come in contact with each other and become conductive to each other. As a result, current flows from a cell 9 and the bulb body 3 can light. At the same time, a flashlight can be taken out from a case 1 for use.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an earthquake-sensing lighting device capable of detecting the vibration when an earthquake occurs and lighting it, and removing the lighting part for use.

[0002]

2. Description of the Related Art Conventionally, a flashlight is attached to a wall surface or the like by a holder so as to be removed and used in an emergency, and when the flashlight is detached from the holder, there is one that lights up. As shown in, there is no flashlight that is automatically set by the vibration when an earthquake occurs.

[Problems to be Solved by the Invention] Japan is one of the most prominent earthquake-prone countries and has been occurring frequently in recent years. The time of occurrence of this earthquake is not specified, but it occurs relatively often from midnight to early morning. That is, since an earthquake occurs during bedtime, when moving up in a house after waking up, the vibration of the feet makes it difficult to reach the ceiling lighting switch. The above-mentioned conventional emergency light is turned on only after the flashlight is pulled out from the holder, and thus is in a non-lighting state until it reaches the destination.
Especially when there is a large seismic intensity and something falls from the shelf or the glass breaks, it is extremely dangerous to groping without lights. At this time, there is no one that can be lighted by an earthquake and can be easily set. The present invention has been invented to solve the above-described problems related to the conventional emergency light, and detects vibration caused by an earthquake and turns on a set flashlight to facilitate indoor walking at night. In addition, the present invention provides a lighting device that can be used by removing the flashlight.

[0004]

As a means for solving the problems, according to the present invention, two conductive plates which are separated by the weight of a mounting object are separated from each other by the movement of the mounting plate caused by the movement of the mounting object generated by the vibration caused by an earthquake. The flashlight that is inserted and held is turned on by contact. That is, in the emergency light system in which the flashlight can be turned on and off by moving the contact that moves in and out of the rear cap end of the flashlight by moving in and out of the predetermined holder, in the upper part of the case containing the battery, There are two upper and lower conductive plates that can be pressed and contacted by springs, and these conductive plates are placed in a non-contact state due to the weight of the object that is placed on the upper conductive plate. The movement of the two conductive plates causes the two conductive plates to be brought into a conductive state, and the inside of the flashlight held by the case is brought into a conductive state to be lit. The present invention is a seismic lighting device having the above configuration.

[0005]

In order to use the present invention, first, the case 1 is attached to a proper place in the room, and the sphere 3 is placed in the circular hole provided in the rotating plate 2. At this time, the lower part of the sphere is located below the circular hole,
The conductive plate 6 is pushed down to bring the conductive plate 5 and the conductive plate 6 into a non-contact state. In addition, with the lid portion of the flashlight processed for the present invention facing upward, the switch is turned on and is inserted and held in the lower portion of the case. By this insertion, the convex portion protruding from the lid is retracted, the conduction inside the flashlight is interrupted, and the state changes to the non-lighting state. This completes the setting. When an earthquake occurs, the sphere vibrates, jumps, and leaves the circular hole. Then, since the rotating plate is pivotally supported by the case, the rotating plate is rotated, and the conductive plates 5 and 6 are brought into contact with each other by the spring to be in a conductive state. Due to this conduction, the current from the dry battery 9 is transmitted to the inside of the flashlight and the bulb can be turned on. And
If you pull out the flashlight from the case, the spring inside the lid will make the interior of the flashlight conductive, and you can continue lighting.

A fan-shaped hole is made in the lid at the rear of a normal flashlight, a holding plate that covers the periphery of a metal plate with an annular insulating plate is located near the inner surface of the lid, and a convex portion is formed on the upper part of the insulating plate. The projection is of a size that allows it to move in and out of the fan-shaped hole, and is formed by fixing a spring for holding the battery to the lower surface of the metal plate. Therefore, when the battery is stored, the metal plate is pushed by the spring and the lid and the metal plate are in contact with each other, so that the light is turned on when the switch is ON. If it is stored in the holder in this state, the convex portion is pushed and the metal plate and the lid are separated from each other, so that the light is turned off. Then, when the flashlight is pulled out from the holder in an emergency, the spring force works to bring the metal plate and the lid into contact with each other, and the light is turned on again. This is the conventional emergency light mechanism.

In the present invention, the flashlight for an emergency light is constructed by forming two holes in the convex portion, passing a copper wire through the hole, and contacting the metal plate. In this example, as shown in FIGS. 3 to 5, a lid 21 is screwed to the rear portion of the case body 20, and an annular recess 22 is formed in the middle of the side surface of the lid.

Then, the conductive plate 11 is connected to the coil spring 7. When the flashlight in the lit state is set in the case, the convex portion 27 is retracted, the conduction inside the flashlight is cut off, and the flashlight is turned off. If an earthquake occurs now, the vibration will cause sphere 3
The conductive plate 5 and the conductive plate 6 come into contact with each other by the jumping and tilting of the rotating plate. Then, a current flows from the positive side of the battery 9, passes through the buzzer, reaches the conductive plate 11 via the coil spring, and the buzzer sounds. In addition, a conducting wire 28 is provided on the end face of the protrusion.
Since it is in contact with the conduction plate 25, the case body 2
