Abstract

PROBLEM TO BE SOLVED: To surely detect operation regardless of the magnitudes of vibration, inclination, and reaction by providing two or more conductors on the internal wall of a case, and causing the conductors to be short-circuited or opened by means of a moving object. SOLUTION: A case 4 is covered on its inside with a film substrate 1, and a first contact 2 is provided in the form of a fence on the circular part of the substrate which corresponds to the upper surface of the case. A second contact 3 is provided in the form of a fence on the circular part of the film substrate which corresponds to the lower surface of the case. By means of vibration, inclination, and reaction caused during the operation of a subject whose operation is to be detected, a conductive sphere 5 is moved and becomes conducting on contact with the contacts 2, 3; when not in contact with the contacts 2, 3, the sphere 5 becomes nonconducting. By detecting these conducting and nonconducting states using an external device, whether or not the subject whose operation is to be detected is operating can be determined. When an operation detecting switch is inclined, for example, since the contacts 2, 3 are arranged alternately also in the circumferential direction the sphere 5 is moved horizontally by the horizontal movement of the subject whose operation is to be detected, and repeats moving into and out of contact with the contacts 2, 3.

In this type of device, a sphere is used to detect vibration, inclination, recoil, etc., and the movement is detected.

For example, the portable alarm device disclosed in Japanese Patent Laid-Open No. 61-180392 is composed of a cylindrical main body, a radial body of a disc portion of the main body, and a metal ball.

In this alarm device, the vibration of the wearer causes the metal sphere to move along the radial wire body, so that when the metal ball comes into contact with the wire body and the outer wall, the vibration is sensed. .

The vibration detecting switch described in Japanese Patent Laid-Open No. 59-60835 is a vibration detecting switch using a magnet. When a vibration such as an earthquake occurs, a ball wrapped in a magnetic material pops out from a hollow in the center of the bottom surface of the reverse cone, It has a structure that attracts the annular magnet on the side wall of the reverse cone to establish a conduction between the reverse cone and the side wall, and the ball is returned to the original hollow at the center of the bottom surface of the reverse cone by manually lifting the ring magnet.

The electric tilt switch disclosed in Japanese Patent Laid-Open No. 62-103931 is a tilt switch in which a ball bearing is sandwiched between an upper cap and a concave dish-shaped lower portion. The bearing moves from the center of the concave dish-shaped lower part and contacts the upper cap and the concave dish-shaped lower part to conduct electricity, thereby detecting the inclination.

The tilt switch described in Japanese Patent Laid-Open No. 4-249019 is a tilt switch in which the inner wall of the casing has a conical shape, and the tilt of the tilt switch causes the sphere to move from the conical bottom surface of the inner wall of the casing to form a cone with the wall surface. It detects that it is tilted by making contact with the bottom surface and conducting it.

The enclosed switch described in Japanese Patent Laid-Open No. 62-165822 is a switch for detecting vibration and inclination by a conductive sphere moving in a space between an upper contact and a lower mortar-shaped contact, and is enclosed. When the switch is tilted or vibrated, the conductive sphere protruding from the lower mortar-shaped contact makes contact with the upper contact and the lower contact to conduct electricity, thereby detecting vibration or tilt.

Falling as described in JP-A-6-52763
The seismic switch is a switch that causes a tumbling and seismic movement with a ball moving in a space surrounded by an upper body and a lower terminal plate.

The vehicle overturning high impact detection device described in Japanese Patent Laid-Open No. 58-189930 is a device for shutting off the power supply system circuit when the vehicle receives an overturn or a strong impact due to an accident.

The cylindrical position detecting switch described in Japanese Utility Model Laid-Open No. 61-42043 is a switch for detecting a position by electrically connecting a contact point provided in a recess of a cylindrical container and a conductive sphere.

The tilt switch described in Japanese Utility Model Laid-Open No. 4-112436 discloses a photo sensor or a switch on the bottom of a cone to detect a sphere, and the tilt of the sphere is detected by the movement of the sphere.

The tilt switch disclosed in Japanese Utility Model Laid-Open No. 62-55842 is a switch having a structure in which a push button rod is provided on the bottom surface of a cone so that the push button rod does not rise rapidly when the sphere is not on the bottom surface of the cone.

The tilted contact described in JP-A-57-189421 is composed of a cylindrical current-carrying body, a conductive sphere, and a donut-shaped current-carrying body.

The vibration sensor described in Japanese Patent Laid-Open No. 61-187621 discloses a plurality of pillars having a conductive portion and an insulating portion, and a conductive sphere that can freely move to a portion surrounded by the plurality of pillars. It is composed of.

As described above, most of the conventional techniques incorporate a moving object such as a sphere in order to detect vibration, inclination, and recoil, and detect whether or not there is a moving object at a predetermined position. .

[0018]

The above-mentioned conventional techniques have problems that weak vibrations cannot be detected, malfunctions occur, or once used, they cannot be used thereafter.

That is, in the portable alarm device described in Japanese Patent Laid-Open No. 61-180392, the metal ball should be able to move freely if it is intended to detect vibration, which is the original purpose. If there is no vibration, it is in a state of being supported by the above-mentioned wire and outer wall, and if there is vibration, it is separated from the above-mentioned wire and the outer wall, and when there is no vibration, it is in a state of being supported again. Due to the returning structure, it is not possible to detect weak vibrations that cannot be separated from the supported state.

In the vibration detecting switch disclosed in Japanese Patent Laid-Open No. 59-60835, a ball that has jumped out of the recess at the center of the bottom surface of the reverse cone due to vibration is attracted to the annular magnet on the side wall. The ball does not return to the original recess at the center of the bottom surface of the inverted cone unless the annular magnet is lifted at. Further, if the vibration detection switch itself tilts in addition to vibration, the ball is attracted by the annular magnet on the side wall, which causes a malfunction.

The electric tilt switch of Japanese Patent Laid-Open No. 62-103931 and the tilt switch of Japanese Patent Laid-Open No. 4-249019 cannot detect vibration or recoil because they cannot be detected unless tilted by a certain angle or more. It is possible.

Similarly, in the enclosed switch described in Japanese Patent Laid-Open No. 62-165822 and the fall / vibration-sensitive switch described in Japanese Patent Laid-Open No. 6-52763, detection cannot be performed unless tilt or vibration is applied over a certain angle. , It is impossible to detect weak vibrations and recoil.

In the cylindrical position detecting switch described in Japanese Utility Model Laid-Open No. 61-42043, the position is detected by the conductive ball entering the above-mentioned recess and conducting to the electrode on the bottom side of the recess. Therefore, since the position is detected depending on whether there is continuity or not, only two states can be detected.

Similarly, the tilt switch described in Japanese Utility Model Laid-Open No. 4-112436, the tilt switch described in Japanese Utility Model Laid-Open No. 62-55842, and the tilt contact described in Japanese Patent Laid-Open No. 57-189421 have only two states. Cannot be detected.

In the vibration sensor described in Japanese Patent Laid-Open No. 61-187621, when the vibration sensor is tilted to be in a conductive state or a non-conductive state, even if the conductive sphere moves by vibration, it contacts in a columnar shape. It remains as it is, and conduction and non-conduction cannot be detected.

The object of the present invention is to solve the above-mentioned problems,
An object of the present invention is to provide a motion detection device that can reliably detect motion regardless of the strength of vibration, inclination, and recoil.

Another object of the present invention is to provide a motion detecting device which is compact, lightweight and has improved productivity.

Still another object of the present invention is to provide an operation detecting device which does not require a power source.

[0029]

The motion detecting device of the present invention is a motion detecting device for detecting the motion of the case by the movement of a moving object having at least the surface made of a conductive material. And detecting the movement of the case by short-circuiting or opening the first conductor and the second conductor by a moving object.

At least one of the conductors is characterized by being discontinuous and formed in a strip shape on the inner wall of the case.

The case has a cylindrical shape, the first conductor is formed in a band-like discontinuity in the vertical direction on the inner surface of the case, and the second conductor is a case without the first conductor. It may be configured to be adjacent to the first conductor in the side surface region and discontinuous in the form of a strip in the vertical direction.

The inner wall of the case between the conductors is recessed from the straight line connecting the ends of the conductors.

It is desirable that the moving object be a conductive sphere.

Since the motion detecting switch of the present invention does not have a structure for supporting the conductive sphere as much as possible, the conductive sphere is free to move inside the cylindrical shape due to the vibration, inclination, and recoil of the motion detection target. Therefore, the reliability can be improved.

Only when the conductive spheres contact the first conductor 2 and the second conductor 3, the conductive state is established.

When the motion detection switch is vertical, the conductive sphere moves horizontally when vibration, inclination, or recoil is applied in the horizontal direction.

In this case, since the first conductor or the second conductor is arranged on the upper and lower surfaces and the circumferential portion of the case, when the conductive sphere contacts the cylindrical portion, When the first conductor or the second conductor is brought into contact with the first conductor or the second conductor in the circumferential portion, the conductive state is established.

When the motion detection switch is tilted and in the horizontal direction, the conductive sphere moves along the circumference.

Also at this time, the first conductor and the second conductor are provided on the circumferential portion.
The conductive spheres are the first because the conductors of
When the conductor and the second conductor come into contact with each other, the state becomes conductive.

When the conductive sphere moves, continuous output of conduction and non-conduction is possible. Therefore, the motion of the motion detection target can be detected by detecting the output.

As described above, according to the present invention, the fact that there is no position and the moving object is moving due to vibration, inclination, or recoil is detected as conducting or non-conducting, so that the object to be detected is moving. Only will be detected.

As a result, vertical vibration, tilt,
In addition to recoil, horizontal vibration, tilt, and recoil can be detected.

Further, regardless of the posture of the motion detection switch, it is possible to detect the vibration, tilt, and recoil of the motion detection target with a single device.

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the present invention will be described.
This will be described with reference to the drawings.

FIG. 1 is a structural diagram of the motion detection switch.

FIG. 2 is a diagram showing the operation principle of the operation detection switch.

FIG. 3 is a vertical sectional view of the motion detection switch.

FIG. 4 is a development view of a film substrate.

In FIGS. 1 to 4, the motion detection switch includes a film substrate 1, a first contact (electrode) 2 formed on the film substrate 1 by, for example, vapor deposition, and a first contact vapor deposited on the film substrate. It is composed of two contact points (electrodes) 3, a case 4 for accommodating the film substrate 1, and a conductive sphere 5 made of a conductive material.

The inside of the case 4 is covered with the film substrate 1, and the first contact (conductor) 2 is provided on the circular film substrate portion corresponding to the upper surface of the case and on the cylindrical film substrate portion in the shape of a fence. Similarly, the second contact (conductor) 3 is provided in a circular film substrate portion corresponding to the lower surface of the case and in a cylindrical shape on the cylindrical film substrate portion. The first contact 2 and the second contact 3 are not connected.

In such a structure, the conductive sphere 5 is caused by vibration, tilt, and recoil when the motion detection target moves.
When is moved to contact the first contact 2 and the second contact 3, it becomes conductive, and when the conductive sphere 5 does not contact the first contact 2 and second contact 3, it becomes non-conductive.

By detecting the conduction or non-conduction by an external device (not shown), it is judged that the motion detection target is moving.

When the motion detection switch itself tilts, the conductive sphere comes into contact with the first contact 2 and the second contact 3 and becomes conductive, and the switch is turned on.

However, the first contact 2 and the second contact 2 are also arranged in the circumferential direction.
Since the contact points 3 are alternately arranged, the conductive sphere 5 also moves horizontally when the motion detection target object moves in the horizontal direction, and the contact point 2 and the contact point 3 are repeatedly contacted and non-contacted. The operation can be detected by repeating the conductive state and the non-conductive state.

When the motion detection switch is used under zero gravity, the conductive sphere 5 comes into conduction when the conductive sphere 5 comes into contact with the first contact 2 and the second contact 3 due to the reaction of the motion detection object. When the motion detection target object is in a stopped state or is in an inertial motion, the conductive sphere 5 does not move, so that the conductive state or the non-conductive state is maintained.

When the object whose motion is to be detected performs a motion that causes acceleration, the conductive sphere 5 moves in reaction to change its state from the conducting state or the non-conducting state.

FIG. 5 shows another embodiment of the present invention (a).
Is a sectional view, and (b) is a perspective view. In FIG. 5, the case 10 is a hexahedron, the electrodes 11 are provided on each surface, and the slits 13 are provided between the electrodes.

FIG. 6 shows still another embodiment of the present invention,
(A) is a sectional view, (b) is a horizontal plane sectional view of (a), and (c) is a perspective view showing a lower case.

In FIG. 6, the side surface of the lower case 21 is notched and has a rectangular side wall. The upper case 20 covers the lower case 21.
It has a convex portion that enters the slit 1 and a concave portion that accommodates the strip-shaped side wall.

[0060]

As described above, in the present invention, the electrodes are alternately formed on the side surfaces of the case, so that continuous pulses are obtained even if the electrodes are rotated in the axial direction of the cylindrical case, and there is no detection error.

Further, the circuit is mechanically opened / closed by contacting the conductive sphere 5 inside the motion detection switch with the upper surface and the lower surface made of a conductive material due to the vibration, inclination or reaction of the motion detection target. This makes it possible to realize a switch that detects an operation without supplying power from the outside.

As a result, it is not necessary to prepare a power supply circuit for the operation detection switch, so that the peripheral circuit can be simplified.

Further, in the present invention, since the contact points are provided in all directions around the conductive sphere 4, it is possible to detect the operation in all directions of 360 °.

This makes it possible to detect the movement regardless of the direction of the switch.

Further, in the present invention, the conductive sphere 4 is displaced from contact to non-contact with the contacts arranged in all directions in the surroundings due to the recoil caused by the motion of the motion detection object, or
By detecting the displacement from non-contact to contact, it is possible to detect the motion of the motion detection target that is not affected by gravity or the like. Therefore, the motion can be detected even in the zero-gravity space.
