Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flashlight which is automatically turned on in the event of an earthquake.

[0002]

2. Description of the Related Art A flashlight is known as a compact lighting device which can be carried by a battery and carried to any place. This flashlight is widely used as an emergency light in the event of a power failure, lighting in dark places such as at night or under the sea, and is used for ordinary homes, hotels, etc., offices of companies, even moving cars, railway cars, etc. It is provided in various places.

Conventionally, the above flashlight has a structure in which a battery and a light bulb are connected in a circuit through a manual switch such as a button type, a slide type or a rotary type. When the switch is not necessary, the switch is turned off to consume power of the battery. prevent. Then, when a flashlight is held in the hand when necessary and the switch is manually turned on, the electric bulb is energized by the battery to be turned on. Also, in order to improve the function as an emergency light, there is one in which a fluorescent paint is applied to a main body of a light or a switch to make it easy to search for a flashlight in a dark place.

[0004]

By the way, in the above-mentioned conventional flashlight, since the flashlight is configured to be held in the hand and turned on by turning on the manual switch, the location of the flashlight is unknown. If you cannot hold it in your hand, you cannot use it. Therefore, for example, in the event of a disaster where a large earthquake occurs at night and a power failure occurs, and furniture in the room collapses at this time, it is not possible to easily find it even with a flashlight, and therefore the flashlight is effectively used. There are things you can't do. Also, in the case of fluorescent paint applied to the main body of the light, the fluorescence itself becomes weak due to aging,
It may not be found if it is hidden behind something, and its practical value is small.

In view of the above points, the present invention has an object to provide a flashlight which is automatically turned on in the event of an earthquake and can be effectively utilized.

[0006]

In order to achieve this object, a flashlight according to claim 1 of the present invention swings with its head on the lighting side facing upward in the vertical state. The main body of the electric light which can be installed and the earthquake detecting switch means provided at the bottom of the main body of the electric light are connected, and the earthquake detecting switch means is connected to the bottom of the main body of the electric lamp when it swings by a predetermined size. It is characterized in that the sensing cap is collided with the collision ring and detached, and the emergency switch is turned on and automatically turned on in conjunction with the detachment of the seismic sensing cap.

A flashlight according to a second aspect of the present invention is provided with a mounting plate which is installed vertically, and a support ring having a front part opened is horizontally fixed to the upper part of the mounting plate, and the main body of the lamp is attached to the support ring. The cap on the lighting side is hooked so that it can be swung back and forth and left and right, and the collision ring of the earthquake detection switch means is fixed to the lower part of the mounting plate coaxially with the support ring. With the earthquake detection cap inserted with a specified gap, it is detachably connected to the bottom of the case of the light body with a predetermined engagement force, and the emergency switch is detached from the bottom of the case and the earthquake detection cap. It is characterized in that it is provided so as to be turned on in conjunction with.

In the flashlight according to a third aspect of the present invention, the seismic detection switch means detects an earthquake when the seismic detection cap collides with the collision ring and separates, and the shape, weight, and gap between the seismic detection cap and the collision ring. The engaging force of the earthquake detection cap with respect to the bottom of the case of the electric light body is set so as to detect an earthquake with a predetermined seismic intensity or more.

In the flashlight according to claim 4, the emergency switch has the permanent magnet built in the seismic detection cap, the reed switch is built in the bottom of the case of the light body by circuit connection with the light bulb and the battery. It is characterized in that it turns off when the seismic detection cap is connected and turns on when the seismic detection cap is disconnected.

The flashlight according to claim 5 is characterized in that the seismic detection cap is connected to the case of the electric lamp main body by a string that bypasses the outside of the collision ring.

[0011]

Therefore, according to claim 1 of the present invention, in the event of an earthquake, the main body of the electric lamp sways in any direction in accordance with its seismic intensity,
At this time, in the seismic detection switch means at the bottom of the electric lamp body with the largest amplitude, the seismic detection cap collides with the collision ring and receives an impact force according to the shaking, and the state of the earthquake is accurately sensed. Then, for example, in the case of a strong earthquake with a seismic intensity of 3 or more, the seismic detection cap is disengaged due to the impact force, and the emergency switch is turned on, thereby automatically lighting up. Therefore, especially in a situation where a power failure occurs at night, it becomes possible to easily find and effectively use the light body.

According to the second aspect of the present invention, the electric lamp main body is inserted into the support ring of the mounting plate and hung so that the electric lamp main body can be easily set. Then, in the event of an earthquake, the mounting plate, the support ring and the collision ring sway together, whereas the heavy electric lamp body and the seismic sensing cap connected to the bottom of the case sway at a different cycle from the seismic sensing cap. Collides with the collision ring and receives an impact force according to the shaking, and thus the state of the earthquake is accurately sensed.

Then, for example, in the case of a strong earthquake with a seismic intensity of 3 or more, the impact force of the seismic sensing cap becomes larger than the engaging force and the seismic sensing cap is disengaged to turn on the emergency switch, whereby the emergency switch is turned on automatically. Therefore, particularly in a situation where a power failure occurs at night, the electric lamp main body can be easily found, and the electric lamp main body can be detached from the support ring and effectively used by grasping the case and pulling it toward you. Further, when the seismic detection cap is removed, the emergency switch is turned on, and the electric lamp main body is removed from the mounting plate, it can be turned off or turned on by a normal manual switch operation, and can be used in the same manner as in the past.

According to a third aspect of the present invention, by appropriately setting the shape and weight of the seismic detection cap, the gap between the seismic detection cap, and the engaging force of the seismic detection cap with the bottom of the case of the electric lamp body, for example, a seismic intensity of 3 or more. Only in case of an earthquake
It becomes possible to turn on automatically.

According to the fourth aspect of the present invention, the emergency switch is operated in a non-contact manner by the permanent magnet and the reed switch, and can be accurately turned on particularly when the seismic sensing cap is detached. Further, the existing flashlight can be used as it is as the main body of the light.

According to the present invention, since the seismic detection cap is tied to the case of the electric lamp body with a string that bypasses the outside of the collision ring, the seismic detection cap is prevented from being lost when it is detached. Also, the string is not caught on the collision ring when the lamp body is removed from the support ring.

[0017]

Embodiments of the present invention will be described below with reference to the drawings. The overall configuration of the flashlight will be described with reference to FIGS. 1 and 2. The flashlight 1 includes a mounting plate 2 that is vertically installed by being screwed to a member A of a wall or a pillar, and a support ring 3 having an opening 3a provided on the upper portion of the mounting plate 2.
Is fixed horizontally apart from the mounting plate 2, and the lamp body 10 is mounted on the support ring 3.

The electric lamp main body 10 has a small-diameter bottomed cylindrical case 11 that can be held in a hand, and a large-diameter cap 12 is attached to the end of the case 11 as a head on the lighting side. This is a structure in which a normal manual switch 13 is provided in the middle of the case 11 or the like. The electric lamp main body 10 hooks the cap 12 on the support ring 3 so that the cap 12 serves as a fulcrum in a vertical state with the cap 12 facing upward,
It is installed so that it can swing in either the left or right direction. The seismic detection switch means 20 is provided between the mounting plate 2 and the case bottom 11a of the electric lamp body 10 having the largest amplitude.

The earthquake detection switch means 20 is mounted on the mounting plate 2.
The collision ring 21 has a closed circular shape and is fixed coaxially with the support ring 3 apart from the mounting plate 2 at a position apart from the case bottom 11a at the lower part of the. Then, in a state where the seismic detection cap 22 is inserted inside the collision ring 21 with a predetermined gap, the case bottom portion 11a of the electric lamp body 10 is inserted.
Detachably connected to. Further, an emergency switch 23 that is automatically turned on in the event of an earthquake is provided between the case bottom portion 11a and the cap 12.

Referring to FIG. 3, the electric lamp main body 10 and the earthquake detection switch means 20 will be described in detail. Electric light body 10
For example, two batteries 14 are connected in series and housed inside the small-diameter case 11. A large-diameter cap 12 is screwed to the end of the case 11 so that the battery can be replaced. A light bulb 16 is attached to the center of a reflecting mirror 15 inside the cap 12, and a transparent glass 17 is attached to the front portion of the cap 12. The light bulb 16
Is brought into contact with and connected to the positive electrode of the battery 14. The negative side of the battery 14 is circuit-connected to the ground side of the light bulb 16 via the coil spring 18, the lead wire 19, and the manual switch 13, and is configured to be turned on and off by the operation of the manual switch 13.

In the seismic detection switch means 20, an seismic detection cap 22 is formed in a bottomed cylindrical shape having substantially the same diameter as that of the case 11, and claws 22b are projectingly provided at a plurality of positions on the circumference of the opening 22a. 22b engages with the outer circumference of the case bottom 11a and is coupled so as to be relatively easily disengaged by the impact force in the radial direction. Further, in order to prevent the detached seismic detection cap 22 from being lost, the seismic detection cap 22 is tied to the case 11 with a string 24 passing through the outside of the collision ring 21.

Here, in the event of an earthquake, the mounting plate 2, the support ring 3, and the collision ring 21 shake together, while the heavy electric lamp main body 10 and the earthquake detection cap 22 shake at a different cycle from that of the earthquake detection cap 22. Collides with the collision ring 21, which makes it possible to detect an earthquake. Therefore, by selecting the shape and weight of the earthquake sensing cap 22 and the gap for the collision ring 21, the impact force at the time of cap collision can be arbitrarily determined. Also,
The greater the seismic intensity during an earthquake, the greater the impact force. Therefore, for example, a predetermined large impact force is generated only in the case of a strong earthquake with a seismic intensity of 3 or more, and the impact force overcomes the engaging force of the claw 22b to remove the seismic sensing cap 22.

The emergency switch 23 is of an electromagnetic type and comprises a permanent magnet 25 and a normally-closed reed switch 26 which operates in a non-contact manner with the magnet 25. The permanent magnet 25 is attached to the seismic sensing cap 22 by a mounting member 27. It is built in substantially at the center of the opening 22a. Further, the reed switch 26 and the lead wire 1 are provided substantially at the center of the case bottom portion 11a.
Built-in circuit connection between 9 and seismic detection cap 22
When the magnet 25 is brought close to the reed switch 26 by engaging with, the magnetic force is turned off by the magnetic force, and when the seismic sensing cap 22 is disengaged and the magnet 25 is separated from the reed switch 26, it is turned on. As a result, when the normal manual switch 13 is turned on, an earthquake detection cap 22
The emergency switch 23 can be turned on by the release of, and the lights can be turned on automatically. Here, since the reed switch 26 is generally built in a glass tube and is weak against impact, a silicon resin 29 as an impact absorbing material enclosed in a container 28 is used.
It is buried in.

Next, the operation of this embodiment will be described. First, the normal manual switch 13 of the electric lamp body 10 is turned on, and the electric lamp body 10 is attached to the mounting plate 2.
Is inserted into the support ring 3 from above, and the cap 12 is hooked on the support ring 3 and suspended. And the case bottom 11
The seismic detection cap 22 of the seismic detection switch means 20 is shown in a.
Of the reed switch 2 of the emergency switch 23 when the string 24 is bypassed to the outside of the collision ring 21 and connected by the claw 22b.
6 is turned off by the magnet 25, so that the circuit on the battery 14 side is shut off and turned off. On the other hand, the earthquake detection cap 22 is located inside the collision ring 21, and the cap 22 can be removed during an earthquake. In this way, the flashlight 1 is easily set as shown by the solid line in FIG. 4A by mounting the lighting main body 10 on the mounting plate 2 and mounting the earthquake detection switch means 20 on the lighting main body 10.

Therefore, when the building shakes in an arbitrary direction due to running of a car, an earthquake, etc., the mounting plate 2, the support ring 3, and the collision ring 21 shake together, and the heavy electric lamp main body 10 and the seismic sensing cap 22 respond thereto. Swings with the cap 12 as a fulcrum in the same direction and at different cycles. Therefore, the seismic detection cap 22 having the largest amplitude collides with the collision ring 21 and receives an impact force according to the shaking, and the seismic state is accurately sensed. The impact force in this case is Case 1
Although it is also transmitted to the first side, the impact is absorbed by the silicon resin 29 inside the case 11 and damage to the reed switch 26 is prevented.

Therefore, even in the case of an earthquake, for example, when the shaking of seismic intensity 3 or less is relatively small and the damage is small, the engaging force of the claw 22b is larger than the impact force at the time of the cap collision. Therefore, the seismic detection cap 22 is held in a connected state as indicated by the alternate long and short dash line in FIG. Therefore, the reed switch 26 is kept turned off and kept in the off state, and unnecessary lighting is avoided.

On the other hand, when a large damage is expected due to a strong earthquake with a seismic intensity of 3 or more, the impact force at the time of the cap collision becomes larger than the engaging force of the claws 22b, and the seismic detection cap 22 is changed as shown in FIG.
As shown in (b), the aircraft broke off, and this large earthquake was accurately detected. In this case, the magnetic force of the magnet 25 is suddenly reduced by removing the cap, and the reed switch 26 is accurately turned on.
As a result, the light bulb 16 is energized by the battery 14 and is automatically turned on immediately. Therefore, even if there is a power failure at night, the flashlight 1 lights up brightly, so even if something inside the room collapses, the location of the flashlight 1 can be clearly known.
Moreover, the vicinity of the flashlight 1 in the room is illuminated and the situation can be grasped.

At this time, when the case 11 of the electric lamp main body 10 is grasped and pulled toward the front, the electric lamp main body 10 can be easily removed by pushing the opening 3a of the support ring 3 open, and thereafter, the electric lamp main body 10 can be removed by hand. It becomes possible to take advantage of it. In this case, the string 24 is previously attached to the collision ring 21.
Since it detours to the outside, it does not get caught on the collision ring 21. Further, the seismic detection cap 22 is always tied to the case 11 by the string 24 so as to prevent the cap 11 from being lost, so that it can be repeatedly used.

Further, when the flashlight 1 is normally used, the reed switch 26 of the emergency switch 23 is always turned on by removing the seismic sensing cap 22 from the case 11 and removing the electric lamp body 10 from the support ring 3. The circuit on the battery 14 side is in the connected state. Therefore, when the normal manual switch 13 is operated to be turned off, it is turned off, and when it is operated to be turned on, the light is turned on, and it is possible to use the switch normally for normal use. Then, for example, before the night sleep, the electric lamp body 1 is again
It is easily set by mounting 0 on the mounting plate 2 as described above. In this way, the flashlight 1 can be used as both a normal illumination light and an emergency light during an earthquake.

Another embodiment of the present invention will be described with reference to FIGS. 5 and 6. FIG. 5 shows a case where a mechanical switch is used as the emergency switch 23. The contact 30 is attached to the case bottom 11a of the electric lamp body 10, and the operation piece 31 is attached to the earthquake detection cap 22 through the hole 32 of the case bottom 11a. The contact 30 is attached so as to be turned on and off. Therefore, also in this embodiment, the contact 30 is turned off and on by the operating piece 31 in accordance with the connection and disconnection of the earthquake detection cap 22, and the same effect can be obtained. Further, since it is a mechanical switch, it has excellent vibration resistance and durability, is easy to manufacture, and is inexpensive.

FIG. 6 shows a case where the electric lamp main body 10 has a straight shape, and the connecting member 35 is integrally mounted on the upper portion of the electric lamp main body 10, and the connecting member 35 is hung on the hanging metal fitting 36 to the front, rear, left and right. It is installed so as to be swingable, and otherwise has the same configuration as that of FIG. Therefore, also in this embodiment, the same effect can be obtained by swinging the straight-shaped electric lamp body 10 by the connecting member 35 and the hanging metal fitting 36 in the event of an earthquake. Also, by providing this kind of hanging means, it can be applied to flashlights of all shapes.

Although the embodiments of the present invention have been described above, the present invention can be similarly applied to the electric lamp main body having a different shape and the waterproof electric diving. The structure of the cap of the earthquake detection switch means and the emergency switch is not limited to the embodiment.

Since it has a structure including an electric lamp main body and an earthquake detection switch means provided at the bottom of the electric lamp main body, it can be automatically turned on by the shaking in the case of an earthquake. For this reason, particularly in a situation where a power failure occurs at night, it becomes possible to easily find and effectively utilize the main body of the lamp, which is very effective in practice. Since the existing electric lamp main body is used and the earthquake detecting switch means is added to the electric lamp main body, the manufacturing is easy and the cost is low. Also, as a means for removing the seismic detection cap, a string is attached to the seismic detection cap without using a collision ring, and the other end of the string is vertically stretched and fixed so that the cap will not move when it is rocked by an earthquake. The structure may be such that the emergency switch is turned off and the emergency switch is turned on.

The seismic detection switch means collides with the collision ring and separates the seismic detection cap connected to the bottom of the main body of the electric light when the electric light body swings by a predetermined amount, and interlocks with the separation of the seismic detection cap. Since the emergency switch is turned on and automatically turned on, it is possible to accurately detect the shaking condition of an earthquake with a simple structure. Therefore, it is possible to reliably and automatically turn on the light in the event of an earthquake with a predetermined seismic intensity or higher.

With the earthquake detection cap inserted with a specified gap, it is detachably connected to the bottom of the case of the light body with a predetermined engagement force, and the emergency switch is detached from the bottom of the case and the earthquake detection cap. Since it is configured to be turned on in conjunction with, it is possible to easily set the electric lamp main body and automatically turn on the light due to the shaking in the case of an earthquake.
In addition, the light body can be easily removed from the support ring and held in your hand for use. Further, the main body of the electric lamp can be used both as a normal illumination lamp similar to the conventional one and as an emergency light in the event of an earthquake, which is versatile.

In the flashlight according to claim 3, the earthquake detection switch means detects an earthquake when the earthquake detection cap collides with the collision ring and separates, and the shape, weight, and gap between the earthquake detection cap and the collision ring. , The engagement force of the seismic detection cap to the bottom of the case of the electric light body is set to detect an earthquake with a predetermined seismic intensity or higher. it can.

In the flashlight according to claim 4, the emergency switch has the permanent magnet built in the seismic detection cap, the reed switch is built in the bottom of the case of the light body by circuit connection with the light bulb and the battery. Since it is turned off when the seismic detection cap is connected and turned on when the seismic detection cap is detached, it can be operated in a non-contact manner and can be accurately turned on particularly when the seismic detection cap is detached. Further, the existing flashlight can be used as it is as the main body of the light.

In the flashlight according to the fifth aspect, since the earthquake detection cap is tied to the case of the light body with a string that circumvents the outside of the collision ring, it is possible to prevent the earthquake detection cap from being lost when it is detached. Also, the string is not caught on the collision ring when the lamp body is removed from the support ring.
