Description

本発明は、電気製品等の機器の転倒状態を検知する転倒検知装置に関するものである。   The present invention relates to a fall detection device that detects a fall state of a device such as an electric product.

近年、加湿機や除湿機等の水に関する機器や石油ファンヒーター等の液体燃料を使用する機器など、液体を扱う一般使用の電気製品が多数商品化されているが、このような電気製品の機器においては通常可搬形態であり固定設置で無い場合が大半であるため、使用上の不注意や地震等の外力により転倒する場合がある。機器の転倒が発生すると扱う液体が漏れ出すこともあり、このような扱う液体が漏れた状態において機器が通電されて運転の状態にあれば機器内部への液体の漏れによる電気回路の故障や発火の原因となり、また機器の外部に漏れると床面や家具の損壊や火災の発生の原因と成り得るために、機器の転倒の状態を検知して報知することや、あるいは機器の運転の状態を停止する安全対策が重要となっている。   In recent years, many general-use electrical products that handle liquids have been commercialized, such as water-related devices such as humidifiers and dehumidifiers, and devices that use liquid fuel such as petroleum fan heaters. In most cases, there are cases in which it is usually portable and not fixedly installed, so it may fall over due to carelessness in use or an external force such as an earthquake. If the device falls, the liquid to be handled may leak, and if the liquid to be handled leaks, if the device is energized and in operation, the electrical circuit may fail or ignite due to the liquid leaking into the device. If it leaks to the outside of the equipment, it may cause damage to the floor or furniture, or cause a fire. Safety measures to stop are important.

従来、この種の機器の転倒状態を検知する方法としては、機器のある程度以上の傾きをスイッチ的に検知する傾斜スイッチが一般的に知られている（例えば、特許文献１参照）。   Conventionally, as a method for detecting the falling state of this type of device, a tilt switch that detects a tilt of the device more than a certain level in a switch manner is generally known (for example, see Patent Document 1).

以下、その傾斜スイッチについて図１６を参照しながら説明する。   The tilt switch will be described below with reference to FIG.

傾斜スイッチの本体の基本を成すケース１０１内部の略円すい状の窪み１０２の先端に円柱状の窪み１０３を備え、上記円柱状の窪み１０３の開口径よりも大きい球体１０４をその上に乗せ、その上から上記球体１０４が略円すい状の窪み１０２上を自由に転がるようにカバー１０５で覆い、かつ、上記円柱状の窪み１０３の底にフォトセンサー１０６を設けて構成したものである。ここで、フォトセンサー１０６は対象に光を投光し対象からの光の反射の有無で対象の有無を検知する反射型のものである。このように構成された実施例の傾斜スイッチが水平の場合には球体１０４が円柱上の窪み１０３に転がり込み、フォトセンサー１０６が球体１０４からの反射光を多く検知することで水平であることを判断することができ、また、傾斜した場合は、球体１０４が円柱上の窪み１０３から傾斜方向に転がり、フォトセンサー１０６は球体１０４からの反射光が少なく、あるいは反射光が受けられなくなり、傾斜の状態を検知することができなくなるために、この状態をもって転倒の判断を実施するものである。   A cylindrical recess 103 is provided at the tip of a substantially conical recess 102 inside the case 101 that forms the base of the tilt switch body, and a sphere 104 larger than the opening diameter of the cylindrical recess 103 is placed thereon, The sphere 104 is covered with a cover 105 so that the sphere 104 can freely roll on the substantially conical recess 102 from above, and a photo sensor 106 is provided on the bottom of the cylindrical recess 103. Here, the photosensor 106 is of a reflective type that projects light onto the object and detects the presence or absence of the object based on the presence or absence of reflection of light from the object. When the tilt switch of the embodiment configured in this manner is horizontal, the sphere 104 rolls into the depression 103 on the cylinder, and the photo sensor 106 detects that the reflected light from the sphere 104 is large, thereby indicating that it is horizontal. In the case of tilting, the sphere 104 rolls in the tilt direction from the depression 103 on the cylinder, and the photosensor 106 has little reflected light from the sphere 104 or cannot receive the reflected light. Since it becomes impossible to detect the state, the judgment of falling is carried out in this state.

実開平０４−１１２４３６号公報Japanese Utility Model Publication No. 04-112436

このような従来の傾斜スイッチにおいては、球体１０４が容易に転がる形状である球形であるために転倒以外の外部からの衝撃等により円柱上の窪み１０３を乗り越え飛び出し易く、外部からの振動に対して誤検知が発生し易かった。   In such a conventional tilt switch, since the sphere 104 is a spherical shape that easily rolls, it is easy to jump over the hollow 103 on the cylinder due to an external impact other than a fall, and against external vibration. False detection was easy to occur.

この誤検知の発生を低減させる方策としては、球体１０４をより転がり難い上面視が円形で重力方向に潰れた準楕円球の形状として、且つ重力方向と同一となる磁束を有するように着磁することで磁束子として、この磁束子を漏斗状の窪みを有し磁束子が内面と１点で接触する内面形状とした凹面容器の内部に可動状態で配置し容器蓋により密閉して、この磁束子の磁束を凹面容器の中央最下部方向に配置された磁束検知手段で検知することで、搭載した機器がある程度以上の傾いたときには磁束子が凹面容器の内面を滑り移動し磁束子の磁束が磁束検知手段の磁束検知範囲から外れ磁束検知手段が非検知状態となり、この磁束が検知されない状態をもって機器の転倒を判断する方式が考えられる。   As a measure to reduce the occurrence of this erroneous detection, the sphere 104 is magnetized so as to have a magnetic flux that is the same as the direction of gravity and the shape of a quasi-elliptical sphere that is more difficult to roll and has a circular top view and is collapsed in the direction of gravity. As a magnetic flux element, this magnetic flux element is movably disposed inside a concave container having a funnel-shaped depression and an inner surface shape where the magnetic flux element contacts the inner surface at one point, and is sealed with a container lid. By detecting the magnetic flux of the child with the magnetic flux detection means arranged in the center bottom direction of the concave container, when the mounted device is tilted more than a certain degree, the magnetic flux element slides on the inner surface of the concave container, and the magnetic flux of the magnetic flux element is A method may be considered in which the magnetic flux detection means deviates from the magnetic flux detection range of the magnetic flux detection means and the magnetic flux detection means is in a non-detection state, and the device is judged to fall with this magnetic flux not being detected.

しかしながら、この方式では搭載する機器に微弱ではあるが周期的に変動する漏洩交流磁界を生じるような開放型隈取磁極型誘導電動機などの磁力の発生源が搭載されているときには、この漏洩交流磁界の磁力変動が磁束子へ影響し、磁束子の有する磁力との間で微弱な引力や斥力が周期的に働くことで、凹面容器の内面と１点にて接触している磁束子自体がついには共振振動に至り接点を中心として回転するなどして凹面容器と磁束子の間で振動音が発生する場合があり、この振動音の発生を抑制するために凹面容器の内部に制動液体を容器蓋により密閉する構成も考えられるが、制動液体を容器蓋で凹面容器の内部に密閉する必要があるために構成が複雑となり、長期の使用においては制動液体が外部に漏れ出し振動抑制の効果が低減するなど課題があった。   However, in this method, when a magnetic source such as an open-type take-up magnetic pole induction motor that generates a weak alternating AC magnetic field that fluctuates periodically is mounted on the mounted device, the leakage AC magnetic field Magnetic flux fluctuations affect the magnetic flux, and weak attracting and repulsive forces periodically work with the magnetic force of the magnetic flux, so that the magnetic flux itself that is in contact with the inner surface of the concave container at one point finally Vibration noise may be generated between the concave container and the magnetic fluxon due to resonance vibration and rotation around the contact point, etc.In order to suppress the generation of this vibration noise, braking liquid is placed inside the concave container. However, the configuration is complicated because it is necessary to seal the braking liquid inside the concave container with a container lid, and the braking liquid leaks to the outside in long-term use, reducing the effect of suppressing vibrations. You There is a problem such as.

本発明は、このような従来の課題を解決するものであり、単純な構成でより長期的に安定した磁束子の振動音の発生を抑制できる効果を備えた転倒検知装置を提供することを目的としている。   The present invention solves such a conventional problem, and an object thereof is to provide a fall detection device having an effect of suppressing the generation of vibration sound of a magnetic fluxon that is more stable in the long term with a simple configuration. It is said.

本発明の転倒検知装置は上記目的を達成するために、上面の開口から漏斗状に窪ませた空間を有する凹面容器の内部にこの凹面容器を水平面上に配置した状態において上面視が円形で重力方向に潰れた準楕円球形状であり、且つ重力方向と同一となる磁束を有するように着磁して磁化した磁束子を配し、この磁束子の磁力を前記凹面容器の下方に配置した磁束検知手段で検知する転倒検知の構成において、前記凹面容器の内部の中央最下位部に前記磁束子の振動を抑制する振動抑制手段を配置したしたものである。   In order to achieve the above object, the fall detection device of the present invention has a circular shape in a top view and a gravitational force in a state where the concave container is arranged on a horizontal plane inside a concave container having a funnel-shaped space from the opening of the upper surface. Magnetic flux that has a quasi-elliptical sphere shape collapsed in the direction and is magnetized and magnetized so as to have a magnetic flux that is the same as the direction of gravity, and the magnetic force of this magnetic flux is arranged below the concave container In the configuration of the fall detection detected by the detection means, a vibration suppression means for suppressing the vibration of the magnetic flux element is arranged at the lowest central portion inside the concave container.

この手段により、機器の通常設置状態においては凹面容器の内部の中央最下位部に配置した振動抑制手段により磁束子が振動することが抑制されることとなる。   By this means, in a normal installation state of the device, the vibration of the magnetic flux element is suppressed by the vibration suppressing means arranged at the center lowest part inside the concave container.

また、振動抑制手段は凹面容器の内部の中央最下位部にこの凹面容器を水平面上に配置した状態において磁束子の一部分が落ち込むようにこの磁束子の上面視の直径よりも小さい直径を有する凹部を設けることで構成したものである。   Further, the vibration suppressing means is a concave portion having a diameter smaller than the top view diameter of the magnetic flux element so that a part of the magnetic flux element falls in a state where the concave container is disposed on the horizontal plane at the central lowermost portion inside the concave container. It is comprised by providing.

この手段により、磁束子は、機器の通常設置状態においては凹面容器の内部の中央最下位部に設けられた凹部に一部分が落ち込むこととなる。   By this means, a part of the magnetic flux falls into the concave portion provided at the lowest central portion inside the concave container in the normal installation state of the device.

また、振動抑制手段は、凹面容器の内部の中央最下位部に凸稜を少なくとも１本設けて前記凸稜を機器の転倒方向を避けて配置する構成としたものである。 The vibration suppression means is a Totsuryo the central lowermost portion of the interior of the concave container at least one set only by those configured to place to avoid the falling direction of the device the convex edge.

この手段により、転倒発生時には磁束子は凹面容器の内部に設けた凸稜には接触し難くできることとなる。   By this means, when a fall occurs, the magnetic flux can hardly contact the convex ridge provided inside the concave container.

また、凸稜の位置は、機器の側面と側面が交わる辺の方向に向けて配置する構成としたものである。   Further, the position of the convex ridge is configured to be arranged in the direction of the side where the side surface of the device intersects the side surface.

この手段により、転倒発生時には磁束子は凹面容器の内部に設けた凸稜には接触し難くできる。   By this means, when a fall occurs, the magnetic flux element can hardly contact the convex ridge provided inside the concave container.

本発明によれば、凹面容器の内部の中央最下位部に配置した振動抑制手段により機器の通常設置状態においては磁束子が振動することが抑制されることとなり、単純な構成でより長期的に安定して凹面容器と磁束子の間で発生する振動音を低減できるという効果を有する転倒検知装置を提供することができる。   According to the present invention, the vibration suppressing means arranged at the central lowest part inside the concave container will suppress the vibration of the magnetic flux element in the normal installation state of the device, and with a simple configuration for a longer period of time. It is possible to provide a fall detection device having an effect of stably reducing vibration noise generated between the concave container and the magnetic flux child.

本発明の請求項１記載の発明は、上面の開口から漏斗状に窪ませた空間を有する凹面容器の内部にこの凹面容器を水平面上に配置した状態において上面視が円形で重力方向に潰れた準楕円球形状であり、且つ重力方向と同一となる磁束を有するように着磁して磁化した磁束子を配し、この磁束子の磁力を前記凹面容器の下方に配置した磁束検知手段で検知する転倒検知の構成において、前記凹面容器の内部の中央最下位部に前記磁束子の振動を抑制する振動抑制手段を配置ものであり、機器の通常設置状態においては振動抑制手段により磁束子が振動することが抑制されるために凹面容器と磁束子の間で生じる振動音を低減できるものであり、単純な構成でより長期的に安定した磁束子の振動音の発生を抑制できる作用を有する。   According to the first aspect of the present invention, in a state in which the concave container is disposed on a horizontal plane inside the concave container having a funnel-like space recessed from the opening on the upper surface, the top view is circular and crushed in the direction of gravity. A magnetic flux magnet magnetized and magnetized so as to have a quasi-elliptical sphere shape and the same magnetic flux as the direction of gravity is arranged, and the magnetic force of this magnetic flux element is detected by a magnetic flux detection means arranged below the concave container. In the configuration of the fall detection, the vibration suppressing means for suppressing the vibration of the magnetic flux element is arranged at the lowest central part inside the concave container, and the magnetic flux element vibrates by the vibration suppressing means in the normal installation state of the device. Therefore, it is possible to reduce vibration noise generated between the concave container and the magnetic flux element, and to suppress the generation of stable vibration sound of the magnetic flux magnet for a longer period with a simple configuration.

また、振動抑制手段は凹面容器の内部の中央最下位部にこの凹面容器を水平面上に配置した状態において磁束子の一部分が落ち込むようにこの磁束子の上面視の直径よりも小さい直径を有する凹部を設けることで構成したものであり、磁束子は機器の通常設置状態においては凹面容器の内部の中央最下位部に設けられた凹部に一部分が落ち込み磁束子と凹部に対する接触部位が増加することとなり、この接触部位の増加により磁束子が振動することが抑制されることで凹面容器と磁束子の間で生じる振動音を低減できるものであり、単純な構成でより長期的に安定した磁束子の振動音の発生を抑制できる作用を有する。   Further, the vibration suppressing means is a concave portion having a diameter smaller than the top view diameter of the magnetic flux element so that a part of the magnetic flux element falls in a state where the concave container is disposed on the horizontal plane at the central lowermost portion inside the concave container. In the normal installation state of the device, a part of the magnetic flux falls into the concave portion provided in the central lowest part inside the concave container, and the contact area with the magnetic flux and the concave portion increases. By suppressing the vibration of the magnetic fluxon due to the increase in the contact area, the vibration noise generated between the concave container and the magnetic flux can be reduced. It has the effect | action which can suppress generation | occurrence | production of a vibration sound.

また、振動抑制手段を凹面容器の内部の中央最下位部に磁束子に接する凸稜を少なくとも１本設けることで構成したものであり、磁束子は機器が非転倒状態においては凹面容器の内面と凸稜との少なくとも２点に接触することとなりこの接触部位の増加により磁束子が振動することが抑制されることで凹面容器と磁束子の間で生じる振動音を低減できるものであり、単純な構成でより長期的に安定した磁束子の振動音の発生を抑制できる作用を有する。   Further, the vibration suppressing means is configured by providing at least one convex ridge in contact with the magnetic flux at the lowest central portion inside the concave container, and the magnetic flux element is connected to the inner surface of the concave container when the device is not overturned. It is possible to reduce vibration noise generated between the concave container and the magnetic flux element by suppressing the vibration of the magnetic flux element due to the increase in the contact area because it comes into contact with at least two points with the convex ridge. It has the effect | action which can suppress generation | occurrence | production of the vibration sound of the magnetic flux child stabilized by the structure for a long term.

また、凹面容器の内部の中央最下位部に凸稜を少なくとも１本設けた振動抑制手段の構成において凸稜を機器の転倒方向を避けて配置する構成したものであり、転倒発生時には磁束子は凹面容器の内部に設けた凸稜には接触し難くなるために磁束子の動は阻害され難く、よって転倒検知の性能を低下させることなく、単純な構成でより長期的に安定した磁束子の振動音の発生を抑制できる作用を有する。   In addition, in the configuration of the vibration suppressing means in which at least one convex ridge is provided at the central lowest part inside the concave container, the convex ridge is arranged avoiding the tipping direction of the device. Since it becomes difficult to contact the convex ridge provided inside the concave container, the movement of the magnetic flux is difficult to be obstructed.Therefore, it is possible to stabilize the magnetic flux in a long term with a simple configuration without deteriorating the fall detection performance. It has the effect | action which can suppress generation | occurrence | production of a vibration sound.

A concave container 5 having 5A, a magnetic element 6 movably disposed inside the funnel-shaped depression 5A, and a central lowermost portion of the funnel-shaped depression 5A (a part surrounded by a one-dot chain line in the figure) And a vibration suppressing means 7 for suppressing the vibration of the magnetic flux element 6 and further covering the entire open space of the concave container 5 in a state where the magnetic flux element 6 is placed inside the concave container 5. A container that is fixed to the circuit board 3 with a lid. And a cover 8. Note that the funnel-shaped recess 5A has a shape that is recessed toward the center.

また、機器の通常設置状態において、凹面容器５は回路基板３の上面側に配置され水平面上に配置した状態になる。   Moreover, in the normal installation state of the apparatus, the concave container 5 is disposed on the upper surface side of the circuit board 3 and disposed on the horizontal plane.

なお、通常設置状態とは、機器を正しく使用するために製造メーカが推奨する機器本体２の設置または使用の姿勢を示す。   Note that the normal installation state indicates the attitude of installation or use of the device main body 2 recommended by the manufacturer in order to use the device correctly.

なお、転倒検知装置１は各種の機器において転倒状態を検知する装置として搭載されて活用することが考えられる。ここでは搭載する機器本体２としては図２に示す加湿装置を一例として示しているものであり、この加湿装置の動作を制御するための制御回路を構成する回路基板３上に転倒検知装置１は配置される。   Note that it is conceivable that the fall detection device 1 is mounted and used as a device for detecting a fall state in various devices. Here, as the device main body 2 to be mounted, the humidifying device shown in FIG. 2 is shown as an example, and the fall detection device 1 is provided on a circuit board 3 constituting a control circuit for controlling the operation of the humidifying device. Be placed.

また、加湿装置においては送風ファン駆動用のモーターとして開放型隈取磁極型誘導電動機を搭載する場合があるが、このモーターから漏洩する交流磁界が前記磁束子６に作用して影響を与えることがある。すなわち、交流磁界が磁束子６に作用して、磁束子６を振動させ、この振動により凹面容器５との間で接触音が発生する。このときの振動を接触振動と呼ぶ。   Further, in the humidifying device, an open type take-up magnetic pole type induction motor may be mounted as a blower fan driving motor, but an alternating magnetic field leaking from this motor may act on the magnetic flux element 6 and affect it. . That is, an alternating magnetic field acts on the magnetic flux element 6 to vibrate the magnetic flux element 6, and a contact sound is generated between the concave container 5 and the vibration. This vibration is called contact vibration.

さらに、この交流磁界の磁力変動が磁束子６へ影響し、磁束子６の有する磁力との間で微弱な引力や斥力が周期的に働くことで、凹面容器５の内面と１点にて接触している磁束子６は、共振振動に至り前記１点を中心として回転するなどして凹面容器５と磁束子６の間で振動音が発生する。このときの振動を回転振動と呼ぶ。   Further, the magnetic force fluctuation of the alternating magnetic field affects the magnetic flux element 6, and a weak attractive force or repulsive force periodically works with the magnetic force of the magnetic flux element 6, thereby making contact with the inner surface of the concave container 5 at one point. The magnetic flux element 6 that has reached the resonance vibration is rotated around the one point, and vibration noise is generated between the concave container 5 and the magnetic flux element 6. This vibration is called rotational vibration.

本実施の形態では、前記漏洩する交流磁界を影響磁力として、また、前記モーターを磁力発生源９として、以下説明をする。   In the present embodiment, the AC magnetic field that leaks will be described as an influence magnetic force, and the motor will be described as a magnetic force generation source 9.

ここで、磁束検知手段４は非接触的に磁束の有無を検知するものであり、例えば磁束密度の有無を検知して電気信号状態に変化させる一般的な面実装形のホールＩＣ７を使用して構成したものである。   Here, the magnetic flux detection means 4 detects the presence or absence of magnetic flux in a non-contact manner. For example, a general surface mount type Hall IC 7 that detects the presence or absence of magnetic flux density and changes the state to an electric signal state is used. It is composed.

ここで、磁束子６は凹面容器５を水平面上に配置した状態、すなわち機器本体２の定常設置状態において回路基板３が水平に配置された状態にて、上方向から見たときに円形で側面方向から見たときに重力方向に潰れた楕円形となる準楕円球の形状すなわち厚さ方向に準楕円形状の偏平形状に形成したものである。そして、漏斗状の窪み５Ａ部分へ可動自在に配置されて、機器本体２の定常設置状態（転倒状態に無い安定した状態）において、重力方向と同一となる方向に磁束を有するように磁化した永久磁石を所定の大きさ成形し構成したものである。その材量としては、例えば、耐食性に優れ保磁力が大きく減磁し難いフェライト磁石が最適であり、準楕円球の形状に成型して焼結後、電磁石の磁束により厚さ方向に着磁して磁石化したものである。   Here, the magnetic flux element 6 has a circular side surface when viewed from above in a state in which the concave container 5 is arranged on a horizontal plane, that is, in a state in which the circuit board 3 is horizontally arranged in a steady installation state of the device body 2. When viewed from the direction, it is formed into a quasi-elliptical sphere shape that becomes an ellipse crushed in the direction of gravity, that is, a quasi-elliptical flat shape in the thickness direction. And it is movably arranged in the funnel-shaped dent 5A portion, and is magnetized so as to have a magnetic flux in the same direction as the direction of gravity in the steady installation state of the device main body 2 (a stable state not in the overturned state). A magnet is formed to a predetermined size. For example, a ferrite magnet with excellent corrosion resistance and a large coercive force that is difficult to demagnetize is the most suitable material. After being molded into a quasi-elliptical sphere and sintered, it is magnetized in the thickness direction by the magnetic flux of the electromagnet. And magnetized.

ここで、凹面容器５、および容器蓋８は磁束子６の有する磁束や磁束検知手段４の検知する磁束へ磁気的に影響しないような材料で形成することが最適であり、例えばＡＢＳやＰＢＴ等の樹脂材料で成型し構成したものである。   Here, the concave container 5 and the container lid 8 are optimally formed of a material that does not magnetically affect the magnetic flux of the magnetic flux element 6 and the magnetic flux detected by the magnetic flux detection means 4. For example, ABS, PBT, etc. The resin material is molded and configured.

ここで、漏斗状の窪み５Ａの中央最下位部は磁束子６と接触している状態において転倒発生時に磁束子６の移動をできるだけ妨げないように摩擦力を少なくする形状が最適である。そして、点接触をさせて摩擦力を少なくするために漏斗状の窪み５Ａは、中央最下位部の内面形状は磁束子６の底面曲率よりも大きい曲率とした半球面または半楕円球面の曲面形状としている。   Here, the lowermost part of the center of the funnel-shaped depression 5A is optimally shaped so as to reduce the frictional force so as not to prevent the movement of the magnetic flux element 6 as much as possible when the fall occurs in a state where it is in contact with the magnetic flux element 6. In order to reduce the frictional force by making point contact, the funnel-shaped depression 5A has a semispherical or semi-elliptical spherical curved surface in which the innermost shape of the lowermost central portion has a curvature larger than the curvature of the bottom surface of the magnetic flux element 6. It is said.

また、図４と図５に示すように、漏斗状の窪み５Ａの中央最下位部には、振動抑制手段７を凹面容器５を水平面上に配置した状態において磁束子６が接触する面に弾性体１０を配置して構成したものである。   Further, as shown in FIGS. 4 and 5, at the center lowest part of the funnel-shaped depression 5A, the vibration suppressing means 7 is elastic to the surface with which the magnetic flux element 6 contacts in the state where the concave container 5 is disposed on the horizontal plane. The body 10 is arranged and configured.

なお、弾性体１０は、磁束子６の接触振動を十分に吸収できるほど凹面容器５の構成材であるところのＡＢＳやＰＢＴ等に対して低硬度な材質であり、合わせてその低硬度の作用により内部損失を大きくして磁束子６の振動による接触音を吸収する材質であって、さらには長期的に安定している材質が適しており、例えばシリコンゴム材で構成するものである。   The elastic body 10 is a material having a low hardness with respect to ABS, PBT, or the like, which is a constituent material of the concave container 5 so that the contact vibration of the magnetic flux element 6 can be sufficiently absorbed. Therefore, a material that increases the internal loss and absorbs the contact sound caused by the vibration of the magnetic flux element 6 and that is stable for a long period of time is suitable. For example, it is made of a silicon rubber material.

また、凹面容器５に対し弾性体１０は図４に示すように漏斗状の窪み５Ａの中央最下位部に弾性体固定窪み１１を設け、この弾性体固定窪み１１に図上、矢印で示した方向、すなわち上方向から弾性体１０を挿入し無理嵌めや接着剤により固設するものである。また図５に示すように漏斗状の窪み５Ａの中央最下位部に弾性体固定開口部１２を設け、この弾性体固定開口部１２に凸形状とした弾性体１０Ａを下方向から嵌め込み挿着させることで構成するものである。   Further, as shown in FIG. 4, the elastic body 10 is provided with an elastic body fixing recess 11 at the lowermost center of the funnel-shaped recess 5A as shown in FIG. 4, and the elastic body fixing recess 11 is indicated by an arrow on the figure. The elastic body 10 is inserted from the direction, that is, from above, and is fixed by forcible fitting or an adhesive. Further, as shown in FIG. 5, an elastic body fixing opening 12 is provided at the lowermost central portion of the funnel-shaped depression 5A, and a convex elastic body 10A is inserted into the elastic body fixing opening 12 from below and inserted. It is constituted by.

ここで、漏斗状の窪み５Ａの中央最下位部に対して弾性体１０の面は突出することなく同一面とすることで、転倒発生時における凹面容器５の内面に対する磁束子６の動きを妨げないように形成することが重要であり、また同様に磁束子６と接する弾性体１０の表面は磁束子６の動きを妨げないように例えば１μｍから１００μｍ程度の厚さのポリエチレンやポリエチレンテレフタラート等の硬質樹脂材でコーティングして接触抵抗を低下させればさらに転倒検知の性能低下への影響を低減することができる。   Here, by making the surface of the elastic body 10 the same surface without projecting with respect to the lowermost central portion of the funnel-shaped depression 5A, the movement of the magnetic flux element 6 with respect to the inner surface of the concave container 5 at the time of falling is prevented. It is important that the surface of the elastic body 10 that is in contact with the magnetic flux element 6 does not interfere with the movement of the magnetic flux element 6, for example, polyethylene or polyethylene terephthalate having a thickness of about 1 μm to 100 μm. If the contact resistance is reduced by coating with a hard resin material, it is possible to further reduce the influence of the fall detection performance.

ここで、凹面容器５の中央最下位部の弾性体１０を配置する範囲は転倒発生時における凹面容器５の内面に対する磁束子６の動きをできるだけ妨げないように、漏斗状の窪み５Ａの内部の中央最下位部で非転倒状態において磁束子６が接触する範囲で良く、例えば磁束子６の上方向から見たときに円直径がΦ５ｍｍであるときにはΦ２ｍｍからΦ３ｍｍの範囲が適している。   Here, the range in which the elastic body 10 at the center lowermost part of the concave container 5 is arranged is arranged inside the funnel-shaped depression 5A so as not to hinder the movement of the magnetic flux element 6 with respect to the inner surface of the concave container 5 as much as possible. The range in which the magnetic flux element 6 contacts in the non-falling state at the center lowest part may be sufficient. For example, when the circular diameter is Φ5 mm when viewed from above the magnetic flux element 6, the range of Φ2 mm to Φ3 mm is suitable.

上記構成によれば非転倒時には磁束子６は、凹面容器５内の漏斗状の窪み５Ａの中央最下位部に位置して、漏斗状の窪み５Ａの中央最下位部の内面と点接触している状態において磁力発生源９からの漏洩交流磁界の磁力の影響を受けて磁束子６が漏斗状の窪み５Ａの内面と点接触している部分を中心として振動や回転動作が誘起されても漏斗状の窪み５Ａの中央最下位部に配置された弾性体１０の低硬度および大きな内部損失の緩衝作用により磁束子６の振動自体が低減され振動音の発生は抑制されることとなる。   According to the above configuration, at the time of non-falling, the magnetic flux element 6 is located at the lowermost central portion of the funnel-shaped recess 5A in the concave container 5 and makes point contact with the inner surface of the lowermost central portion of the funnel-shaped recess 5A. The funnel 6 is influenced by the magnetic force of the leakage AC magnetic field from the magnetic force generation source 9 and vibration or rotational motion is induced around the portion where the magnetic flux element 6 is in point contact with the inner surface of the funnel-shaped depression 5A. The vibration itself of the magnetic flux element 6 is reduced by the low hardness of the elastic body 10 arranged at the lowermost central portion of the hollow 5A and the buffering action of a large internal loss, and the generation of vibration noise is suppressed.

また、図６に示すように振動抑制手段７は、凹面容器５内部の漏斗状の窪み５Ａの中央最下位部に非転倒時に磁束子６の一部分が落ち込むように磁束子６の上面視の直径以下の凹部１３を設けることで構成することもできる。   Further, as shown in FIG. 6, the vibration suppressing means 7 has a diameter in a top view of the magnetic flux element 6 so that a part of the magnetic flux element 6 falls into the lowermost central portion of the funnel-shaped depression 5 </ b> A inside the concave container 5 when not falling. It can also be configured by providing the following recess 13.

ここで、凹部１３の開口は磁束子６が落ち込んだ状態において漏斗状の窪み５Ａとの接触部位を多くして接触抵抗を大きくできるように上方向から見たときの形状は真円形が最適であり、その直径は非転倒時に磁束子６が漏斗状の窪み５Ａの中央最下位部へ滑り込む状態において抵抗にならない程度の大きさとする必要があり、例えば磁束子６の上方向から見たときに円直径がΦ５ｍｍであるときにはΦ２ｍｍからΦ３ｍｍの範囲が適している。   Here, the shape of the opening of the concave portion 13 when viewed from above is optimal so that the contact resistance can be increased by increasing the contact portion with the funnel-shaped depression 5A in a state where the magnetic flux element 6 is depressed. The diameter of the magnetic flux element 6 needs to be large enough not to become a resistance when the magnetic flux element 6 slides into the lowermost central part of the funnel-shaped depression 5A when not overturned. For example, when viewed from above the magnetic flux element 6 When the circle diameter is Φ5 mm, the range of Φ2 mm to Φ3 mm is suitable.

ここで、凹部１３の開口は磁束子６が落ち込んだ状態において磁束子６が凹部１３の底面と接触して凹面容器５との間で１点接触の状態が発生しない程度の深さに設定する必要があり、例えば磁束子６の上方向から見たときに円直径がΦ５ｍｍで側面方向から見たときの高さ方向の寸法が３ｍｍであり、凹部１３の穴径がΦ３ｍｍであったときにはこの穴深さは０．４ｍｍ以上が適している。   Here, the opening of the concave portion 13 is set to such a depth that the magnetic flux element 6 comes into contact with the bottom surface of the concave portion 13 and the one-point contact state does not occur with the concave container 5 when the magnetic flux element 6 is depressed. For example, when the circular diameter is Φ5 mm when viewed from above the magnetic flux element 6 and the height dimension when viewed from the side surface is 3 mm, the hole diameter of the recess 13 is Φ3 mm. A hole depth of 0.4 mm or more is suitable.

上記構成によれば非転倒時の凹面容器５の中央最下位部に磁束子６が位置する状態においては凹面容器５の中央最下位部の配置された凹部１３に磁束子６の一部分が落ち込み、磁束子６の表面は凹部１３の開口端と線状に接触して磁束子６と凹面容器５の間で大きな接触抵抗が生じることで、この接触抵抗が磁束子６に磁力発生源９からの漏洩交流磁界の磁力が影響している状態においても磁束子６を共振状態に至らせず振動の発生を防止することができ、磁束子６の回転振動や接触振動が原因となる振動音の発生は抑制されることとなる。   According to the above configuration, in a state where the magnetic flux element 6 is positioned at the central lowest part of the concave container 5 at the time of non-falling, a part of the magnetic flux element 6 falls into the concave part 13 arranged at the central lowest part of the concave container 5; The surface of the magnetic flux element 6 is in linear contact with the opening end of the concave portion 13, and a large contact resistance is generated between the magnetic flux element 6 and the concave container 5, and this contact resistance is applied to the magnetic flux element 6 from the magnetic force generation source 9. Even in the state where the magnetic force of the leakage AC magnetic field is affected, it is possible to prevent the occurrence of vibration without bringing the magnetic flux element 6 into the resonance state, and the generation of vibration sound caused by the rotational vibration or contact vibration of the magnetic flux element 6. Will be suppressed.

また、図７に示すように振動抑制手段７は、凹面容器５内部の漏斗状の窪み５Ａの中央最下位部に凸部１４を突設させることで構成することもできる。   Moreover, as shown in FIG. 7, the vibration suppression means 7 can also be comprised by making the convex part 14 protrude in the center lowest part of the funnel-shaped hollow 5A inside the concave container 5. As shown in FIG.

ここで、凸部１４は転倒発生時においては凹面容器５の内面を滑る磁束子６の動きをできるだけ妨げず、且つ非転倒時の磁束子６が漏斗状の窪み５Ａの中央最下位部に位置する状態においては磁束子６との接触部分で磁束子６の一部を僅かに浮かせる形状に突設させる必要があり、例えば磁束子６の上方向から見たときに円直径がΦ５ｍｍで側面方向から見たときの高さ方向の寸法が３ｍｍであれば半径０．２ｍｍから０．３ｍｍの半球形状が適している。   Here, the convex portion 14 does not obstruct the movement of the magnetic flux element 6 that slides on the inner surface of the concave container 5 as much as possible when the fall occurs, and the magnetic flux element 6 at the time of the non-falling position is positioned at the lowermost central portion of the funnel-shaped depression 5A. In such a state, it is necessary to project the part of the magnetic flux element 6 so that it slightly floats at the contact portion with the magnetic flux element 6. For example, when viewed from above the magnetic flux element 6, the circle diameter is Φ5 mm and the lateral direction If the dimension in the height direction when viewed from 3 mm is 3 mm, a hemispherical shape with a radius of 0.2 mm to 0.3 mm is suitable.

上記構成によれば非転倒時の凹面容器５の中央最下位部に磁束子６が位置する状態においては凹面容器５の中央最下位部に突設させた凸部１４に磁束子６が乗り上げた状態となり、磁束子６は凸部１４との接触部分と凹面容器５と接している部分との２点で凹面容器５に対して保持され、この凹面容器５内の漏斗状の窪み５Ａに対する磁束子６の２点での接触により磁束子６と凹面容器５の間で大きな接触抵抗が生じることで、この接触抵抗が磁束子６に磁力発生源９からの漏洩交流磁界の磁力が影響している状態においても磁束子６を共振状態に至らせず振動の発生を防止することで、磁束子６の回転振動に基づく振動音の発生は抑制されることとなる。 According to the above configuration, in a state where the magnetic flux element 6 is located at the central lowest part of the concave container 5 when not falling, the magnetic flux element 6 has run on the convex part 14 protruding from the central lowest part of the concave container 5. The magnetic flux element 6 is held with respect to the concave container 5 at two points, that is, a contact portion with the convex portion 14 and a portion in contact with the concave container 5, and the magnetic flux with respect to the funnel-shaped depression 5 </ b> A in the concave container 5. by contact at two points of the child 6 by Jisokuko 6 and large contact resistance between the concave container 5 occurs, the magnetic force of the leakage AC field of the contact resistance from the magnetic force generating source 9 to Jisokuko 6 is affected Even in the state where the magnetic flux element 6 is present, the generation of the vibration sound based on the rotational vibration of the magnetic flux element 6 is suppressed by preventing the occurrence of vibration without bringing the magnetic flux element 6 into the resonance state.

また、図８および図９に示すように振動抑制手段７は、凹面容器５の内部の中央最下位部に磁束子に接する凸稜１５を少なくとも１本（図上、一例としては凸稜１５は３本）を突設させることで構成することもできる。   Further, as shown in FIGS. 8 and 9, the vibration suppressing means 7 has at least one convex ridge 15 in contact with the magnetic flux element at the central lowermost portion inside the concave container 5 (in the figure, as an example, the convex ridge 15 is It can also be configured by projecting three).

ここで、凸稜１５は転倒発生時においては凹面容器５の内面に対する磁束子６の動きをできるだけ妨げず、且つ非転倒時の磁束子６が凹面容器５の中央最下位部に在る状態においては磁束子６と凸稜１５の１部分以上が接触するように凹面容器５の中央から外側に放射状の稜形状に突設させる必要があり、例えば磁束子６の上方向から見たときに円直径がΦ５ｍｍで側面方向から見たときの高さ方向の寸法が３ｍｍであれば凹面容器５の中央から外側に放射状の高さ０．２ｍｍから０．３ｍｍの稜線形態に突設させる形状が適している。   Here, the convex ridge 15 does not obstruct the movement of the magnetic flux element 6 with respect to the inner surface of the concave container 5 as much as possible when the fall occurs, and the magnetic flux element 6 at the time of non-falling is in the lowermost central portion of the concave container 5. Needs to project in a radial ridge shape outward from the center of the concave container 5 so that at least one part of the magnetic flux element 6 and the convex edge 15 is in contact, for example, when viewed from above the magnetic flux element 6 If the diameter is Φ5mm and the height dimension when viewed from the side is 3mm, the shape of the ridgeline with a radial height of 0.2mm to 0.3mm projecting from the center to the outside of the concave container 5 is suitable. ing.

上記構成によれば非転倒時の凹面容器５の中央最下位部に磁束子６が在る状態においては磁束子６は凹面容器５の内面の１点と凹面容器５の中央最下位部から放射状に突設させた凸稜１５の稜線上の一部に接触した状態で保持され、この凹面容器５に対する磁束子６の２点以上での接触により磁束子６と凹面容器５の間で大きな接触抵抗が生じることで、この接触抵抗が磁束子６に磁力発生源９からの漏洩交流磁界の磁力が影響している状態においても磁束子６を共振状態に至らせず振動の発生を防止するために、磁束子６の回転振動や接触振動が原因となる振動音の発生は抑制されることとなる。 According to the above configuration, in the state where the magnetic flux element 6 is present at the lowest central portion of the concave container 5 when not overturned, the magnetic flux element 6 radiates from one point on the inner surface of the concave container 5 and from the lowermost central portion of the concave container 5. Is held in contact with a part of the ridge line of the convex ridge 15 projecting on the concave container 5, and the contact between the magnetic flux element 6 and the concave container 5 due to the contact with the concave container 5 at two or more points. by resistance occurs because the contact resistance to prevent the generation of vibrations without bring the Jisokuko 6 into resonance even in a state where the magnetic force is affecting the leakage AC magnetic field from the magnetic force generating source 9 to Jisokuko 6 In addition, the generation of vibration noise caused by rotational vibration and contact vibration of the magnetic flux element 6 is suppressed.

なお、図１０に示すように搭載する機器本体２の筐体が、例えば４角柱形状であれば機器本体２の転倒方向もほぼ４方向に限定される。すなわち、図に太矢印で示すように筐体の側面方向に限定できる。このように搭載する機器本体２の転倒方向が限定できるときには、図１１に示したように凹面容器５の内面において機器本体２の転倒方向と同一となる方向（図上、太矢印で示した方向）を避けて凸稜１５を配置すれば転倒発生時に磁束子６が凹面容器５の内面を転倒方向に滑り移動する際に凸稜１５に磁束子６が接触し難くすることができるために、凸稜１５に対する磁束子６の接触抵抗に基づく転倒検知性能低下への影響をより低減させることができる。特に、凸稜の向きは、側面と側面が交わる辺の方向へ向けることで容易に機器の転倒方向と同一となる方向を避けることができる。   In addition, as shown in FIG. 10, if the housing | casing of the apparatus main body 2 mounted, for example is a quadrangular prism shape, the fall direction of the apparatus main body 2 will be limited to substantially four directions. That is, it can be limited to the side surface direction of the housing as indicated by a thick arrow in the figure. When the fall direction of the device body 2 to be mounted can be limited in this way, the direction (the direction indicated by the thick arrow in the figure) that is the same as the fall direction of the device body 2 on the inner surface of the concave container 5 as shown in FIG. If the convex ridge 15 is arranged avoiding the above), it is possible to make it difficult for the magnetic flux element 6 to contact the convex ridge 15 when the magnetic flux element 6 slides in the falling direction on the inner surface of the concave container 5 when the fall occurs. The influence on the fall detection performance degradation based on the contact resistance of the magnetic flux element 6 with respect to the convex ridge 15 can be further reduced. In particular, the direction of the convex ridge can be easily avoided in the direction that is the same as the direction in which the device falls by being directed toward the side where the side faces intersect.

また、以上の実施の形態の説明のなかで、凹面容器は、機器の通常設置状態において、水平面上に位置するように配置することで、単純な構成でより長期的に安定した磁束子の振動音の発生を抑制できる作用を 簡単な形状の凹面容器と磁束子と振動制御手段を用いて実現することができる。   In addition, in the description of the above embodiment, the concave container is disposed so as to be positioned on a horizontal plane in a normal installation state of the apparatus, thereby stabilizing the vibration of the magnetic flux element with a simple configuration for a longer period of time. The effect of suppressing the generation of sound can be realized by using a concave container, a magnetic flux element, and vibration control means having a simple shape.

なお、以上の説明においては転倒検知装置１は搭載される機器本体２に内蔵される回路基板３と、この回路基板３の下面側に配置される磁束検知手段４と、凹面容器５と、磁束子６と、容器蓋８とから複合的に構成された装置として示しているが、この構成要素を一体として単独デバイス部品として機能させることも可能であり、この単独デバイス部品においても振動抑制手段７を備えることで磁束子の振動音の発生を抑制できる作用効果に差異が無いことは言うまでも無い。   In the above description, the fall detection device 1 includes the circuit board 3 built in the equipment body 2 to be mounted, the magnetic flux detection means 4 disposed on the lower surface side of the circuit board 3, the concave container 5, and the magnetic flux. Although shown as a device composed of a child 6 and a container lid 8 in a composite manner, it is possible to make this component function as a single device part as a unit, and also in this single device part, vibration suppressing means 7 It goes without saying that there is no difference in the operational effect that can suppress the generation of the vibration sound of the magnetic flux.

なお、以上の説明においては転倒検知装置１は機器本体２の通常設置状態において、重力方向に対して直角となるように配置されるすなわち略水平に配置される平板状の回路基板３に構成された装置として示しているが、回路基板３が傾斜や、あるいはほぼ垂直な角度となる構成においても凹面容器５の形状や磁束検知手段４の配置角度を考慮すれば転倒検知の装置として機能させることも可能であり、この転倒検知装置１を略水平配置する以外の構成においても振動抑制手段７を備えることで磁束子の振動音の発生を抑制できる作用効果に差異が無いことは言うまでも無い。   In the above description, the fall detection device 1 is configured as a flat circuit board 3 that is arranged so as to be perpendicular to the direction of gravity in the normal installation state of the device body 2, that is, substantially horizontally. However, even if the circuit board 3 is inclined or has a substantially vertical angle, it can function as a fall detection device if the shape of the concave container 5 and the arrangement angle of the magnetic flux detection means 4 are taken into consideration. Needless to say, there is no difference in the effect of suppressing the generation of the vibration sound of the magnetic flux magnet by providing the vibration suppressing means 7 even in the configuration other than the horizontal arrangement of the fall detection device 1. .

なお、実施の形態１に対して同一の機能の構成には同一の図番を振り以降の詳細な説明は省くものとする。   It should be noted that the same function numbers are assigned to the same function configurations as those in the first embodiment, and detailed description after that is omitted.

ここで、図１２は本転倒検知装置の参考例１の構成を示す正面視断面図、図１３は同装置を搭載した機器の構成例を示した正面斜視部分透過図である。 Here, FIG. 12 is a front cross-sectional view showing the configuration of Reference Example 1 of the fall detection device, and FIG. 13 is a front perspective partial perspective view showing a configuration example of a device on which the device is mounted.

図１２に示すように、転倒検知装置構成１に内蔵される磁束子６と同一機器内に配置した磁力発生源９の間に磁束を遮断する防磁手段１６を配置することで磁束子６に対する磁力発生源９からの漏洩交流磁界の影響を低減させることもできる。   As shown in FIG. 12, the magnetic force with respect to the magnetic flux element 6 is arrange | positioned by arrange | positioning the magnetic-shielding means 16 which interrupts | blocks magnetic flux between the magnetic force generation source 9 arrange | positioned in the same apparatus with the magnetic flux element 6 incorporated in the fall detection apparatus structure 1. FIG. The influence of the leakage AC magnetic field from the generation source 9 can also be reduced.

ここで、防磁手段１６は鉄材やニッケル材を主成分とした透磁率が高いアモルファス構造やパーマロイ組成の軟質磁性金属材料を平板形状や樹脂フィルムに蒸着して形成したものである。   Here, the magnetic-shielding means 16 is formed by vapor-depositing a soft magnetic metal material having a high magnetic permeability of iron or nickel and having a high magnetic permeability and a permalloy composition on a flat plate or resin film.

ここで、防磁手段１６は機器本体２に対しては例えば図に示したように螺子１７で取り付けて固設するものである。   Here, the magnetic-shielding means 16 is attached and fixed to the apparatus main body 2 with screws 17 as shown in the figure, for example.

なお、防磁手段１６を磁束子６に対して近距離に配置すると磁石であるところの磁束子６との間で磁気的引力が働き磁束子６が凹面容器５の内面の防磁手段１６の配置方向に引きつけられて転倒発生時においては磁束子６が凹面容器５の内面を滑り移動する妨げとなるために磁束子６と防磁手段１６との間隔は磁気的引力がほぼ無視できる距離に離す必要があり、例えば磁束子６の表面磁力が１５０ｍＴ程度であれば磁束子６と防磁手段１６は最低でも１３ｍｍ以上の間隔を空けて配置することが望ましい。   When the magnetic shielding means 16 is arranged at a short distance from the magnetic flux element 6, the magnetic attractive force acts between the magnetic flux element 6 as a magnet and the magnetic flux element 6 is disposed in the direction of the magnetic shielding means 16 on the inner surface of the concave container 5. When the overturn occurs, the magnetic flux element 6 hinders the sliding movement of the inner surface of the concave container 5, so that the distance between the magnetic flux element 6 and the magnetic shielding means 16 needs to be set at a distance where the magnetic attractive force can be almost ignored. For example, if the surface magnetic force of the magnetic flux element 6 is about 150 mT, it is desirable that the magnetic flux element 6 and the magnetic-shielding means 16 are arranged at least 13 mm apart.

なお、防磁手段１６は磁力発生源９から発生する磁束子６に対して影響を与える磁束子６が振動やあるいは回転しない程度に十分に影響磁力を低減できる程度にその面積や軟質磁性金属材料の厚みを調節する必要があり、実際の活用においては搭載する機器において影響磁力の低減効果を確認して決定するものである。   It should be noted that the magnetic shielding means 16 has an area and a soft magnetic metal material that can sufficiently reduce the magnetic force to such an extent that the magnetic flux 6 that affects the magnetic flux 6 generated from the magnetic force source 9 does not vibrate or rotate. It is necessary to adjust the thickness, and in actual use, it is determined by confirming the effect of reducing the influence magnetic force in the mounted device.

上記構成によれば搭載する機器に磁束子６を振動させる影響を与える磁力を発生する磁力発生源９が存在していても、この磁力発生源９と磁束子６との間に配置した防磁手段１６により磁束子６への磁力発生源９からの磁力の影響を低減させることができるために、この直接的な磁束子６への影響磁力の低減により磁束子６の振動や回転自体の発生を抑止できることとなり磁束子６の回転振動や接触振動が原因となる振動音の発生は抑制されることとなる。   According to the above configuration, even if there is a magnetic force generation source 9 that generates a magnetic force that affects the mounted device to vibrate the magnetic flux element 6, the magnetic-shielding means disposed between the magnetic force generation source 9 and the magnetic flux element 6. 16 can reduce the influence of the magnetic force from the magnetic force generation source 9 on the magnetic flux element 6, so that the direct influence of the magnetic force on the magnetic flux element 6 can reduce the vibration and rotation of the magnetic flux element 6. The generation of vibration noise caused by the rotational vibration and contact vibration of the magnetic flux element 6 is suppressed.

なお、以上の説明においては転倒検知装置１は搭載される機器本体２に内蔵される回路基板３と、この回路基板３の下面側に配置される磁束検知手段４と、凹面容器５と、磁束子６と、容器蓋８とから複合的に構成された装置として示しているが、この構成要素を一体として単独デバイス部品として機能させることも可能であり、この単独デバイス部品においても磁力発生源９の間に防磁手段１６を配置することで磁束子の振動音の発生を抑制できる作用効果に差異が無いことは言うまでも無い。   In the above description, the fall detection device 1 includes the circuit board 3 built in the equipment body 2 to be mounted, the magnetic flux detection means 4 disposed on the lower surface side of the circuit board 3, the concave container 5, and the magnetic flux. Although shown as a device composed of a child 6 and a container lid 8 in a composite manner, it is also possible to make this component function as a single device part as a unit, and even in this single device part, a magnetic source 9 It goes without saying that there is no difference in the operational effect that can suppress the generation of the vibration sound of the magnetic flux by disposing the magnetic shielding means 16 between them.

なお、以上の説明においては転倒検知装置１は機器本体２の通常設置状態において、重力方向に対して直角となるように配置されるすなわち略水平に配置される平板状の回路基板３に構成された装置として示しているが、回路基板３が傾斜や、あるいはほぼ垂直な角度となる構成においても凹面容器５の形状や磁束検知手段４の配置角度を考慮すれば転倒検知の装置として機能させることも可能であり、この転倒検知装置１を略水平配置する以外の構成においても磁力発生源９の間に防磁手段１６を配置することで磁束子の振動音の発生を抑制できる作用効果に差異が無いことは言うまでも無い。   In the above description, the fall detection device 1 is configured as a flat circuit board 3 that is arranged so as to be perpendicular to the direction of gravity in the normal installation state of the device body 2, that is, substantially horizontally. However, even if the circuit board 3 is inclined or has a substantially vertical angle, it can function as a fall detection device if the shape of the concave container 5 and the arrangement angle of the magnetic flux detection means 4 are taken into consideration. There is also a difference in the operational effect that can suppress the generation of the vibration sound of the magnetic flux by disposing the magnetic shielding means 16 between the magnetic force generation sources 9 even in the configuration other than the horizontal arrangement of the fall detection device 1. Needless to say there is nothing.

14 and 15 show a configuration diagram of the fall detection device in Reference Example 2 of the present invention.

なお、同一の機能の構成には同一の図番を振り以降の詳細な説明は省くものとする。   It should be noted that the same function number is assigned to the same function configuration, and detailed description after that is omitted.

ここで、図１４は本転倒検知装置の参考例２の構成を示す正面視断面図、図１５は同装置を搭載した機器の構成例を示した正面斜視部分透過図である。 Here, FIG. 14 is a front cross-sectional view showing the configuration of Reference Example 2 of the present fall detection device, and FIG. 15 is a front perspective partial transparent view showing a configuration example of a device on which the device is mounted.

図に示すように、転倒検知装置構成１に振動抑制手段７を備えて、さらに転倒検知装置構成１に内蔵される磁束子６と磁力発生源９の間に防磁手段１６を配置することで、磁束子６への磁力発生源９からの影響磁力を低減しながら、さらに磁束子６の振動自体を抑制させることもできる。   As shown in the figure, the fall detection device configuration 1 is provided with the vibration suppression means 7, and further, by arranging the magnetic shield means 16 between the magnetic flux element 6 and the magnetic force generation source 9 built in the fall detection device configuration 1, While reducing the influence magnetic force from the magnetic force generation source 9 to the magnetic flux element 6, the vibration of the magnetic flux element 6 can be further suppressed.

上記構成によれば搭載する機器に磁束子６を振動させる影響を与える磁力を発生する磁力発生源９が存在していても、この磁力発生源９と磁束子６との間に配置した防磁手段１６により磁束子６への磁力発生源９からの磁力の影響を低減させつつ、さらに非転倒時の磁束子６が凹面容器５の中央最下位部に磁束子６が在る状態においては 磁束子６は振動抑制手段７により振動の誘発自体が抑制されるために、さらに効果的に磁束子６の回転振動や接触振動が原因となる振動音の発生は抑制できることとなる。   According to the above configuration, even if there is a magnetic force generation source 9 that generates a magnetic force that affects the mounted device to vibrate the magnetic flux element 6, the magnetic-shielding means disposed between the magnetic force generation source 9 and the magnetic flux element 6. 16, while reducing the influence of the magnetic force from the magnetic force source 9 on the magnetic flux element 6, the magnetic flux element 6 in the state where the magnetic flux element 6 at the time of non-falling is located at the lowest central part of the concave container 5 6, since vibration induction itself is suppressed by the vibration suppression means 7, generation of vibration sound caused by rotational vibration and contact vibration of the magnetic flux element 6 can be more effectively suppressed.

なお、以上の説明においては転倒検知装置１は搭載される機器本体２に内蔵される回路基板３と、この回路基板３の下面側に配置される磁束検知手段４と、凹面容器５と、磁束子６と、容器蓋８とから複合的に構成された装置として示しているが、この構成要素を一体として単独デバイス部品として機能させることも可能であり、この単独デバイス部品においても振動抑制手段７を備え、また磁力発生源９の間に防磁手段１６を配置することで磁束子の振動音の発生を抑制できる作用効果に差異が無いことは言うまでも無い。   In the above description, the fall detection device 1 includes the circuit board 3 built in the equipment body 2 to be mounted, the magnetic flux detection means 4 disposed on the lower surface side of the circuit board 3, the concave container 5, and the magnetic flux. Although shown as a device composed of a child 6 and a container lid 8 in a composite manner, it is possible to make this component function as a single device part as a unit, and also in this single device part, vibration suppressing means 7 Needless to say, there is no difference in the effect of suppressing the generation of vibration sound of the magnetic flux by disposing the magnetic shielding means 16 between the magnetic force generation sources 9.

なお、以上の説明においては転倒検知装置１は機器本体２の通常設置状態において、重力方向に対して直角となるように配置されるすなわち略水平に配置される平板状の回路基板３に構成された装置として示しているが、回路基板３が傾斜や、あるいはほぼ垂直な角度となる構成においても凹面容器５の形状や磁束検知手段４の配置角度を考慮すれば転倒検知の装置として機能させることも可能であり、この転倒検知装置１を略水平配置する以外の構成においても振動抑制手段７を備え、また磁力発生源９の間に防磁手段１６を配置することで磁束子の振動音の発生を抑制できる作用効果に差異が無いことは言うまでも無い。   In the above description, the fall detection device 1 is configured as a flat circuit board 3 that is arranged so as to be perpendicular to the direction of gravity in the normal installation state of the device body 2, that is, substantially horizontally. However, even if the circuit board 3 is inclined or has a substantially vertical angle, it can function as a fall detection device if the shape of the concave container 5 and the arrangement angle of the magnetic flux detection means 4 are taken into consideration. In addition to the configuration in which the fall detection device 1 is arranged substantially horizontally, the vibration suppression means 7 is provided, and the antimagnetic means 16 is arranged between the magnetic force generation sources 9 to generate the vibration sound of the magnetic flux child. Needless to say, there is no difference in the function and effect that can be suppressed.
