Abstract

PROBLEM TO BE SOLVED: To detect the lateral tremor or the vertical tremor of an earthquake or the like with high sensitivity by enclosing a vibration element composed of a conductive spring and a disk in a conductive cylinder, and taking out a contact between the vibration element and the cylinder resulting from a vibration as an electrical signal. SOLUTION: One end of a conductive spring 101 is pierced through the nonconducting body 104 provided on the top face 103 of a conductive cylinder 102 so as to form an electrode bar 105a, and further another electrode bar 105b connected to the cylinder 102 is provided on the top face 103. The other end of the spring 101 is pierced through the conductive disk 106 so as to form a protrusive stylus 107 on the bottom face side, and the disk passing through portion thereof is soldered. When the disk 106 vibrates in the horizontal direction or in the vertical direction in resonance with an earthquake or the like, the disk 106 touches the inside face 108 of the cylinder 102, or the stylus 107 touches the bottom face 109 of the cylinder 102 so that the electrode bars 105a, 105b become equipotential and the same are brought into the same state as switch-on. Thereby, when the vibration element is fitted to a stove, a heater, or an alarm device, a vibration is detected so that damage can be prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a horizontal direction, a vertical direction,
And a vibration unit for sensing vibration in an arbitrary direction, detecting the corresponding vibration and replacing it with an electric signal, and controlling safety measures such as an alarm device to which the electric signal corresponds. The present invention relates to a vibration sensing device.

[0002]

2. Description of the Related Art Conventionally, there has been a high-sensitivity uniaxial vibration sensor using an optical method, but since many devices are relatively large devices, there are difficulties in selecting the direction of installation and portability.
I never incorporated it in my bag or toys. There are also microcomputer meters that cut off gas during strong earthquakes, but those that cut off electricity are rarely considered.

[0003]

The conventional optical system has a very sensitive function with respect to vibrations in a predetermined single axis direction, but has a structure in which it is difficult to detect vibrations in various axis directions. There was a difficulty in portability.

For this reason, there has been no device that reacts sensitively to the horizontal or vertical shaking of an earthquake and shuts off the current during a strong earthquake, such as an earth leakage breaker.

In addition, for a bag or the like, there is a method such as lifting the buzzer by detecting it when there is an action such as lifting at a predetermined fixed angle or opening the lid, but some kind of bag is used. There was no device that immediately sensed as a sway when a movement occurred and gave an alarm.

[0006] Alternatively, there is a method in which an electronic melody sound is generated for a certain period of time when an action such as pushing a specific portion of the stuffed toy is applied, but when the toy itself is arbitrarily tilted or rolled, it is sensed as shaking. It never played any audio. The present invention has been made to solve these disadvantages.

[0007]

In the vibration sensing device according to the first aspect of the present invention, the vibration element constituted by the conductive spring 101 and the conductive disk 106 is connected to the conductive cylinder 102.
When the vibrating element is suspended in the axial direction of the cylinder by mounting the vibrating unit A113 enclosed therein in the vertical direction, the disk 1 is vibrated in the horizontal or vertical direction.
When 06 resonates and makes physical contact with the conductive cylinder 102, it is detected as a change in electrostatic capacity, and is further replaced with an electric signal to control the power breaker via a relay circuit, thereby changing the commercial power supply path to the indoor wiring path. It is characterized by blocking and separating.

According to another aspect of the vibration sensing device of the present invention, two sets of vibration units B210 in which a cylindrical conductor 204 is enclosed in a non-conductive cylinder 201 provided with a conductive plate member 202 and a conductive wire member 203 are provided. Arranged in the cross axis direction and mounted on a bag, etc., the cylindrical conductor rolls when the bag is lifted or tilted, and the capacitance changes when the plate material and the wire material make electrical contact therethrough. Is detected, and is further replaced with an electric signal to control the application unit via the relay circuit to reproduce a recorded warning message or the like.

According to another aspect of the vibration sensing device of the present invention, the vibrating element composed of the conductive spring 301 and the conductive plate member 302 is made to face each other at positions just before contact so as to form a hexahedron. A vibrating unit C313, which is enclosed inside a large-sized hexahedron, is formed, and is detected as a change in capacitance when the plate member 302 resonates due to horizontal or vertical vibration and the two vibrating elements physically contact each other. In addition, the application circuit is controlled by replacing it with an electric signal and controlling an application circuit to reproduce a voice or the like that has been recorded for a certain period of time.

The reset switch of claim 4 is turned on so that only a specific person can release the safety measure such as the alarm device in the operating state of the vibration sensing device of claims 1 and 2. A unique PIN code without using electronic active elements or circuits by combining a plurality of slide switches adjacent to each other by arbitrarily combining the OFF slide directions and electrically connecting them in parallel to form a power switch. A feature is that a combination of switches capable of providing a function is configured.

[0011]

In the vibration sensing device according to the first aspect of the present invention, it is possible to forcibly cut off the power supply when an earthquake occurs by detecting the horizontal and vertical shaking of the earthquake. For this reason, the most common cause of fires caused by an earthquake is that an electric stove in use or a heater for tropical fish falls when the earthquake falls or the wiring is damaged. It is possible to prevent such problems.

In the vibration sensing device according to the second aspect of the present invention, various states are conceivable, such as a case where the bag such as an attache case is placed vertically on the floor or a case where the bag is placed sideways on the net shelf. It detects vibrations of the bag that violate its will as vibrations and generates warning sounds and messages to help prevent damage such as theft.

In the vibration sensing device according to the third aspect of the present invention, when the vibration sensing device is mounted on a stuffed toy or a toy, it is sensed as vibration in various axial directions. Can be played, or mother's voice recording tape can be played.

In the embodiment of the reset switch according to claim 4, the persons other than the specific person and the owner in claim 1 and claim 2 cannot easily cancel the safety measure or stop the warning sound. The combination pattern of the slide positions of the switches is used as a secret code to protect.
