Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a wiring device embedded in a building wall, and connected to and mounted on an electric machine, a machine or the like.
The present invention relates to electrical safety equipment, fire prevention and fire protection equipment, and security equipment for general homes and facilities, which can be selectively used according to the purpose of use by automatically switching the energized state at the time of vibration sensing operation.

[0002]

2. Description of the Related Art A conventional vibration sensing device requires a large number of circuits and electronic components for turning on and off the power after sensing a vibration with a vibration sensing unit. However, there is no such technology for the outlet and the switch in the embedded wiring device.

The main power supply of the emergency light, which automatically turns on upon sensing vibrations such as earthquakes, uses a dry battery or a rechargeable battery. The dry battery cannot be used due to self-discharge or the like. There was also a risk of rupture due to charging.

[0004] Further, since there is no device that automatically turns on the embedded switch of the lighting equipment in the event of an earthquake, there is also a waste of electricity that goes to bed with the indoor lighting equipment turned on in preparation for a nighttime earthquake.

[0005] In addition, indoor lighting fixtures equipped with a device that senses and lights vibrations have a risk of simultaneous dropping at a ceiling or other mounting place due to an increase in weight and an increase in volume.

In addition, vibrations and shocks cause failures for equipment, and it is required to incorporate a device for shutting off a power supply for protection of the equipment. However, the weight and volume of the equipment are increased. There was inconvenience. In addition, they were often deleted because they were not cheap.

[0007] Although there are devices and facilities such as fire extinguishing facilities that respond after a fire has occurred, there are few effective devices that cut off electricity, which is one of the causes of a fire when an earthquake occurs, only when necessary.

[0008]

Conventionally, it has been widely known that a fire such as gas is eliminated when an earthquake occurs, but it has not been well known to unplug a power plug of an electric product from an outlet. However, because the power plug was still plugged in, the switch was turned on due to falling objects, etc., despite equipment that had an earthquake-resistant stop device, and damage to electrical products and short-circuiting of the power cord could cause a fire in the event of an earthquake. Obtained. In addition, in the event of a major earthquake while sleeping at night, there is no need to wait for the shaking to settle down. There were many things. In general, when manually operating a breaker when evacuating after an earthquake, it is not possible to judge whether the indoor evacuation situation is complete because all power including the lighting is shut off. In an emergency, it is extremely difficult, and there is a problem about who will ultimately operate the breaker at which point, as well as how to install the breaker and how to operate it. In addition, in an unspecified large number of facilities such as customer attracting facilities, it is assumed that operation is impossible depending on actual site conditions including responsibilities. Also,
Evacuation behavior itself is not easy for vulnerable people such as children, the elderly and the disabled, and it is considered impossible to operate a breaker in an emergency. In addition, the idea of automatically turning off the breaker means that the power including the lighting is indiscriminately and uniformly shut off, which may lead to further damage. Therefore, it is best to comprehensively secure the necessary parts such as the evacuation route etc. by automatically turning on the individual evacuation lights with the switch part and automatically shutting off the individual equipment at the outlet part for the equipment to be shut off. Is determined.

[0009] Further, it has been impossible to pull out the power plug from all outlets of the house calmly in an emergency.

[0010] Further, at the time of a large earthquake at night, it was difficult to find a flashlight or to switch on a lighting device.

In the case of an emergency light which automatically detects the vibration of an earthquake and detects the vibration of the earthquake, if the dry battery or rechargeable battery which is the upper power source is left for a long time, the life of the dry battery and the It may not be usable due to discharge,
When used for a long time, the amount of light is insufficient and the battery cannot be put to practical use. In addition, the rechargeable battery has a risk of explosion due to overcharging.

Also, even if a power failure occurs immediately after a large earthquake, if the electrical product is damaged due to a fall or the like and the power cord is compressed by a fallen object, the damaged portion or the compression portion may generate heat after the restoration of the power failure. A fire occurred at the same time, and firefighting activities were not possible, causing large-scale and severe damage.

When an earthquake occurs near the sea, it is necessary to evacuate to a hill immediately in a coastal area due to the fear of a tsunami. However, in the absence of a tsunami, such as when a fire had occurred in an out-of-home residence, no initial firefighting activities could be performed.

Not only during an earthquake, but also when a general electric machine or the like has artificial vibrations or abnormal vibrations generated by the electric machine or the like itself, the vibrations or shocks cause failure or abnormal operation. Sometimes it occurred.

In addition, in the case of a sensor using a conventional sphere, it is necessary to obtain the construction accuracy in the front-rear, left-right, and up-down directions. Met.

The present invention is small in size so that it can be used for machines, devices and instruments, etc., where the installation place is limited in the past, and when vibration is sensed, power supply and cutoff can be selectively used, and furthermore, the operation is simple. It works reliably in case of emergency,
An object is to provide a highly reliable device at low cost.

[0017]

In order to achieve the above object, a vibration sensing mechanism of a vibration sensing operated automatic power on / off switch mechanism with a built-in outlet according to the present invention is a switching micro switch (9). It is also used as a mechanism for starting up.

Further, in the vibration detecting mechanism of the present invention, when the vibration detecting mechanism is operated, the vibration detecting mechanism is used as an automatic on / off switch or used as an automatic shut-off outlet. The determination can be easily made only by selecting the wiring employed in the present apparatus.

Further, in the automatic power supply opening / closing switch mechanism of the present invention, the vibration sensing mechanism utilizes a natural fall due to shaking, so that it is left for a long period of time unlike the conventional apparatus. When this was done, there was a malfunction due to rust or deterioration of the parts.However, in this device, all the rotating contact surfaces are made of heat-resistant reinforced resin, metal weights etc. are surrounded with resin, etc. .

Further, even when the house is tilted, it does not return unless the knob is rotated by hand, so that it does not return erroneously even if the house is tilted.

[0021]

The outlet-integrated vibration-sensing actuated automatic power on / off switch mechanism constructed as described above is connected to the embedded outlet (13) by the common terminal line (15) and the normally closed terminal line (1).
If the 6) is connected in series, the power supply is automatically cut off when vibration such as an earthquake is detected, so even if the electrical product is damaged or the power cord is short-circuited, the power supply from the embedded outlet The supply is cut off, which prevents electricity from flowing.

When the common terminal line (15) and the normally open terminal line (17) are connected in parallel to the embedded switch (12), the lighting equipment is automatically turned on when vibration is sensed. It is effective in earthquakes, and the presence of light makes it easy to perform calm judgments and danger avoidance actions. In addition, the use of this device to shut off and supply power during an earthquake seems to be contradictory, but when investigating the cause of a fire during an earthquake, many of the power sources remain plugged into a power outlet. Due to products, fires from lighting equipment wired indoors were rare. Some people think that a power failure will occur immediately after the earthquake, but power transmission will continue as long as there is no abnormality in the power transmission facilities. Therefore, it is necessary to secure the minimum necessary lighting during evacuation, and then disconnect the power cord of electrical appliances that may cause a fire, to ensure safety.With this device, it is possible to respond to the demand for power supply and cutoff. I can do it.

Further, the device according to the present invention exerts its effect by adding the functions which the device can have when the conventional switch and the embedded outlet are in an emergency. Therefore, it can be used as a normal switch and an embedded outlet in normal times.

It was inserted into the shaft of the knob (2), fixed with pine needles (7), the dustproof cover (14) was fitted to the front plate, and the lever (8) was attached to the fixed plate (10) so as to rotate. Later, the switching type micro switch (9), which is mounted on the outer casing (4) of the main body and wired for the common terminal line (15), the normally closed terminal line (16) and the normally open terminal line (17), is mounted, By mounting (11), when vibration is detected, the power supply is automatically switched to the common terminal line (15) and the normally closed terminal line (16) and the normally open terminal line (1).
7) A device that can be switched between the two could be constructed.

FIG. 2 shows an embodiment relating to the use of the device according to the present invention. As shown in FIG. 2, the embedded switch (1) is mounted on the wiring device mounting frame (3) of the device constructed above.
2) Alternatively, it could be constructed by mounting the embedded outlet (13) and mounting the back plate (11).

[0026]

Since the present invention is configured as described above, it has the following effects.

Although the operation is very simple, there is no accidental start-up due to a falling object or the like which a conventional device has, such as a push button type.

Further, since the number of parts is reduced, it is possible to obtain a small-sized apparatus having high reliability, a long life, and easy maintenance and inspection.

Further, since the electric circuit is only the turning on and off of the microswitch, a device which does not require driving power by itself can be obtained.

Further, when vibration is sensed, the power supply of the embedded outlet is turned off, and even when an electric product such as a refrigerator that has a power cord inserted for a long time is connected, a dustproof cover is attached to the front plate. By mounting the device, it is possible to provide a device that is not easily affected by vibration detection without attaching dust or dust to the rotating knob.

When the embedded switch is automatically turned on at the time of detecting vibration, it is possible to secure the safety by obtaining the illumination and to eliminate the need for special lighting equipment. An effect can be added, and such an effect can be easily added to a lighting fixture already installed.

Further, since the lighting equipment used at all times is turned on, the light quantity is superior to that of a flashlight or the like, and the long-term reliability is higher than that of a flashlight or special lighting equipment.

If the embedded switch is automatically turned on at the time of detecting vibration, the lighting equipment is turned on, so that there is no need to go to bed with the night illumination on, and it is possible to contribute to energy saving.

Further, if the power supply of the embedded outlet is automatically turned off at the time of detecting vibration, it is effective to prevent the power supply fire in the event of a large earthquake, and even if the function of the firefighting equipment at the time of the earthquake is paralyzed. If a fire does not occur, rescue operation can be delayed and human damage can be further reduced.
