Description

[Detailed Description of the Invention] The object of the present invention is to provide a seismic switch that switches on due to vibrations.

The present invention will be described in detail below based on examples. 1st
FIG. 2 shows an embodiment of the present invention, in which a rotary wheel 22 is rotatably supported at both ends by switch mounting pieces 20 arranged opposite to each other, and the center between the two shafts 21 is shown. At the position, the shaft 2 at both ends of the idler wheel 23
4 is rotatably supported, a contact 2 made of a conductive weight of an idler wheel 23 is attached, and the contact 2 always maintains a horizontal state no matter which direction the device to which the switch mounting piece 20 is attached is turned. It has a so-called gyroscope structure. Here, the other contactor 1 is attached to the lower end of the support piece 3 which is swingably connected to the idler wheel 23, and in a non-vibration state, it maintains a predetermined insulating distance from the one contactor 2. When this occurs, it swings and comes into electrical contact with one of the contacts 2. In addition, other structural examples of the contacts 1 and 2 are shown in FIGS. 3 to 5, and the support piece 3 may be constructed of a coil spring as shown in FIG. 6. Figure 7a,
In b, the number of contacts 1 is increased, and the degree of contact is increased. FIG. 8 shows the above-mentioned idler wheel 23 configured in a semicircular shape. In FIGS. 9a and 9b, one support piece 3 is planted on the conductor 25 attached to the idler wheel 23, and the other support piece 3 is placed on the conductor 25 through a path insulated from the conductor 25. The spherical contacts 1 and 2 are installed at the upper ends of both supporting pieces 3 in an insulating manner. Figure 10a and b are conductors 2
A switching action is performed between the contact 1 at the upper end of the support piece 3 having spring properties implanted on the support piece 5 and the rib-like contact 2 of the idler ring 23. In each of the embodiments described above, the idler wheel 23 may be constituted by a hollow idler ball 26 as shown in FIG. Alternatively, the mounting plate 27 may be supported by a spring 28 so that vibrations are more sensitively felt. In FIG. 12, each shaft 24 of an idler wheel 23 is extended inward, and contacts 1 and 2 are attached to the inner ends of both shafts 24, respectively. Another contact 1 located in the hollow part of the contact 2 is supported by a swingable support piece 3. FIG. 13 shows another embodiment of the contactor 2. In the embodiment shown in FIGS. 1 to 14 above, both contacts 1 and 2 are connected to a pair of paths which are insulated from each other by an insulator 29 provided on an idler ring 23 and a rotating ring 22. It is electrically connected to the switch mounting piece 20, and both switch mounting pieces 20 constitute a terminal, respectively. FIG. 15 shows an embodiment of the mounting structure for the insulator 29. . Furthermore, although the idler wheels 23 are used in each of the embodiments described above, the present invention may be applied to a configuration in which the idler wheels 23 are omitted as shown in FIG.

Therefore, the seismic switch 15 configured as described above is used as a switch element when it is desired to detect vibrations and drive necessary electric appliances when vibrations occur. It can be applied in any case where it is needed, and one example of its application is shown in FIGS. 17 to 19. This application example shows a case where it is applied to a standing light, and the seismic switch 5 and the seismic switch 5
A switch circuit 7 is constructed from a delay operation element 6 which maintains an on state for a predetermined period of time in response to an on signal from the switch circuit 7, and this switch circuit 7 is assembled into a mounting base 9 of a standing light 8. A standing light 8 is configured to be detachably attached to a mounting base 9 made of synthetic resin that is fixed to an appropriate part such as a wall or a pillar, and a switch storage portion 10 that bulges forward is formed at the top of the mounting base 9. A switch circuit 7 is housed in this switch housing section 10. Further, a holding protrusion 11 is provided from the approximate center of the mounting base 9 toward the front, and a hole 13 formed at the approximate center line of the case 12 of the standing light 8 is inserted into the holding protrusion 11. When placed over the holding protrusion 11, the mounting contact plate 15 is connected to the positive or negative electrode of the adjacent battery 17 via the insulator 14 on both the upper and lower surfaces, and the standing lamp 8 is mechanically held. It's summery. Both the contact plates 15 each have a lead wire 1
6 is connected to terminals A and B of the switch circuit 7, and when the standing light 8 is attached to the holding protrusion 11,
A switch circuit 7 will be inserted in series between the batteries 17.

Next, the delay operation element 2 that constitutes the switch circuit 7
is a function that operates in conjunction with the seismic switch 5, and when the seismic switch 5 turns on for a moment, it receives this on signal and remains on for a predetermined period of time, for example, 30 to 40 seconds, and then turns off. It has
FIG. 19 shows an example in which the device is constructed using an electronic circuit. Here 18 is a light bulb, BL ₁ ,
RL ₂ is a relay, RL ₁ S is an interlocking switch for relay RL ₁ , and RL ₂ S ₁ and PL ₂ S ₂ are relay switches for relay RL ₂ , which are normally connected to the b side. Tr ₁ and Tr ₂ are transistors, C is a capacitor, and VR is a variable resistor. However, due to the vibration, the seismic switch 5
When is momentarily turned on, relay RL ₁ is activated and its associated switch RL ₁ S is turned on. Then, current flows through the base of transistor Tr ₁ to charge capacitor C, and transistors Tr ₁ and Tr ₂
turns on and operates Ray RL ₂ . Therefore, the light bulb 18 lights up and each relay switch is turned on.
When RL ₂ S ₁ and RL ₂ S ₂ are switched from the b side to the a side and the seismic switch 1 is turned off, charging of the capacitor C continues for a predetermined period of time, and the light bulb 18 continues to be lit. . When charging of capacitor C is completed, transistors Tr ₁ and Tr ₂ are both turned off,
Relays RL ₂ and RL ₁ are also turned off, and the light bulb 18 is turned off. The delay operation of relay RL ₂ is determined by the time constant of capacitor C and variable resistor VR, and the delay time can be adjusted by adjusting variable resistor VR. If the seismic switch 5 is turned on again while the capacitor C is being charged during the above operation, the capacitor C will be discharged, but the transistors Tr ₁ and Tr ₂ will remain on. The delay time will be extended. In other words, as long as the seismic sensor switch 5 is repeatedly turned on electrically, the delay time is extended, and the relay is activated for the specified period of time from when the vibrations stop.
RL ₂ is turned off. Here, the seismic switch 5 is the first

The present invention rotatably supports the shafts at both ends of an idle shaft at the center position between the shafts of a rotary ring, the shafts at both ends of which are rotatably supported by switch mounting pieces arranged opposite to each other. One contact element made of a conductive weight is provided on the idler wheel, and the other contact element is provided at the lower end of the support piece that is swingably connected to the idler wheel, so that the device to which the switch mounting piece is attached can be used. No matter which direction the contactor is turned, the contactor can always maintain a horizontal state, and stable switch performance can be obtained regardless of the installation conditions of the mounting bracket of this seismic switch. Since the contacts are electrically connected to the switch mounting pieces through paths that are insulated from each other by insulators provided on the idle ring and the rotating ring, the switch mounting pieces constitute a structure that prevents lead wires from being connected to In addition, the installation conditions are not limited by the lead wire, and therefore the advantages of the structure using a rotating ring and an idler ring as described above can be fully utilized. Also, when vibrations occur due to an earthquake, the contact supported by the support piece swings, contacts the other contact, and conducts between the two contacts, resulting in a switch.The vibration is detected and the switch is activated. By using this vibration detection element as a switching element for electrical appliances, it has the effect of being widely applicable to crime prevention equipment, earthquake alarms, disaster prevention equipment, etc.
