Abstract

PURPOSE: To sense an earthquake and automatically interrupt an electric circuit by providing a conical body top type vibration sensitive pendulum, a disc clamp, and a pressing element for pressing a cantilever spring contact terminal to a ratchet with beam so as to bring into contact with it. CONSTITUTION: A switch pressing element 16 provided on a ratchet with beam 10 presses a cantilever spring contact terminal 17 onto a fixed contact terminal 18 and brings it into contact with it, whereby an electric circuit is closed to make a current flow, and laid in usable state. When an earthquake takes place in this state, a conical body top type vibration sensitive pendulum 3 is fallen down, the disc clamp 5 of a shaft 4 acts on the lever 7 of a claw with beam to operate the lever 7, and the claw 6 of the claw with beam is released from the tooth 11 of a ratchet 10. Thus, the ratchet 10 is reversely rotated by the elasticity of a power spring 13, and touched and stopped by a reverse rotation ratchet stopper 14. The pressing element 16 is moved upward by this rotation, the terminal 17 is returned and separated from the terminal 18 to open the electric circuit, and the current is interrupted. Since the electric circuit is thus automatically interrupted at the earthquake, occurrence of an electric fire can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is an automatic electrical circuit breaker for earthquakes, a straw anti-seismic breaker. On January 17, 1995, Japan experienced a rare earthquake in history, centering around Kobe and Awaji. The catastrophe exceeded the death toll of 5,100 people and destroyed the house of 70,4
It is possible to know seriously that there are 500 buildings.
I would like to devote my heart to the victims. A major feature of this great earthquake is the occurrence of a large fire. It is said that not only gas and oil stoves, but also many electric stoves. The reason is that after a few days, the electric wire was restored and when I turned on the power, a fire broke out. When an earthquake occurs, you can rest assured that the electricity will be turned off automatically. I definitely want such a safety device. Therefore, the invention was invented. The features of the present invention are briefly set forth in the claims. Claim 1
Describes the technical concept of the automatic seismic circuit breaker itself, and claim 2 describes the most preferable embodiment. Specific examples of the invention are shown in the drawings. The operation of the present invention will be described below. The conical drum top type pendulum (3), which is a seismic body, has its axis (4) as a hole (2) in the base (1) and a hole (8) in the lever (7) of the claw (6) with a lever (7). It is installed on the base (1) with the disc stopper (5) as a stop. Claws (6) with lever (7) are rods (12)
It is bitten by the teeth (11) of the ratchet wheel (10). It is the power spring (13) that acts to apply a load to the claw (6) that holds the state, the claw (6) is fitted into the tooth (11), and the base (1) is horizontal. If it is stationary, the claw (6) holding the pendulum (3) upright is a spring (9). In this state, the pusher (16) of the switch provided on the ratchet wheel (10) presses the cantilever spring contact terminal (17) against the fixed contact terminal (18) to bring them into contact with each other. The electrical circuit is now closed, i.e. ready for current flow, i.e. in use. An earthquake came there. The seismic pendulum (3) swings and falls. The clasp (5) of the shaft (4) of the pendulum (3) acts on the lever (7), the lever (7) operates, and the pawl (6) moves from the tooth (11) of the ratchet wheel (10). Come off. Then, the ratchet wheel (10) is reversed by the elasticity of the power spring (13) and hits the reverse claw wheel stopper (14) to stop. By this rotation, the pusher (16) of the switch escapes upward, and the cantilever spring contact terminal (17)
Returns and disengages from the fixed contact terminal (18), the electric circuit opens and current cannot flow. This is the reason why the Suwara Seismic automatic electrical circuit breaker (anti-seismic breaker) acted against the earthquake. The earthquake is over. Fortunately, the installation location was not damaged. It seems that electricity has been restored. Push the straw rod (12) up. The ratchet wheel (10) rotates in the forward direction, and the pusher (16) of the switch provided on the ratchet wheel (10) moves downward to push down the cantilever spring contact terminal (17) to contact the fixed contact terminal (18). That is, the switch is closed and current can flow. By the normal rotation, the teeth (11) of the ratchet wheel (10) come to the point where they bite the nail (6), and the nail (6) is fitted on the teeth (11) by the elasticity of the nail holding spring (9). Therefore, the ratchet wheel (10) stops by hitting the forward rotation ratchet wheel stopper (15) provided with slight play so as not to rotate any more. At this time, the tilted pendulum (3) is set upright by the action point of the lever (7) of the lever claw (6) pushing the disc stopper (5) of the shaft (4) of the pendulum (3). This anti-earthquake breaker has been restored. And we will prepare for an earthquake that we may not know when it will come again. As can be seen from the operation of the present invention described above, the present invention automatically operates and interrupts the electric circuit due to an earthquake, so that an electric fire or the like caused by an earthquake can be prevented in advance. It is extremely useful for earthquake disaster prevention. When it comes to practical use, I would like you to attach it to each door. But the more ideal is to place it on the distribution pole. This is because the electricity will be cut off more fundamentally, and the accident rate will decrease accordingly. Therefore, considering various possibilities, the wiring place of the electric pole is high, and wiring to a low place is required to mount the present invention, and various incidental equipments are required to secure the management, and the cost is enormous. It turns out that it is not practically applicable. It turns out that this must be installed in every door.
Currently, each unit is equipped with an overcurrent breaker. Since it is a safety device, installation is obligatory. It will be understood that a seismic-to-overcurrent breaker in which the present invention and its breaker are integrated is practically necessary. Then, looking at whether the present invention can meet the requirement, it is quite possible. Conventional breakers use the action of a metal plate that burns and expands due to overcurrent. The principle of the dual-use breaker may be applied exactly. In the embodiment of the present invention, this overcurrent extending metal plate need only be provided so as to act as close as possible to the fulcrum of the lever (7) of the lever with claw. If the overcurrent extending metal plate is extended by the overcurrent, the lever (7) is pushed thereby, and the claw (6) is released. It will be seen that it is extremely easy to design and put into practical use. Since I was able to invent this anti-earthquake and overcurrent automatic electric circuit breaker, I declare that copyright has occurred,
I would like to apply for a separate patent later within the legal period. The present invention must be installed horizontally and vertically at the time of installation. There may be cases where the pillars of the house are tilted, so an accessory to correct it horizontally and vertically is also necessary. We have also devised a mounting base that allows a vertical mounting surface to be exposed with four screws. It seems that a level is used for the adjustment, but a micro level may be attached to this mount. Normally, two levelers are integrally provided so that the front, rear, left and right can be seen, but in the present invention, it is provided on a cantilever plate bar, and the plate bar can be stored by a pin joint. Good. Considering the case where the house is tilted due to an earthquake, even in that case people who want to restore electricity should put the present invention in advance, and many people would like to adjust by themselves without requesting an electrician when necessary. From
The present invention has unexpected demand and seems to be useful. The seismic actuation device employed in the invention of the embodiment of the present invention is based on the conventional idea, or it may not be understood that there is an inventor who still owns the copyright. Of course, if you look younger, you will have to pay a royalty for commercialization. No matter what I do, I often have to enjoy the benefits of teacher technology. The evolution of technological thought is a function of the times. As an inventor, I cannot but thank him for his technical ideas. Since the present invention is a safety device, it is not known that its installation will be mandatory. If this happens, the demand range will become vast and a solid business will be created. I would like to put it into practical use as soon as possible and prepare for the fear of the great earthquake. The present invention was not born without the Great Kobe Awaji Earthquake. I would like to once again devote myself to the disaster victims.
