　本願は、日本国特願２０１５－１７４５４８号の優先権を主張し、引用によって本願明細書の記載に組み込まれる。 This application claims the priority of Japanese Patent Application No. 2015-174548, and is incorporated herein by reference.
　本発明は、低周波治療器及び低周波治療器用のパッド部に関するものである。 The present invention relates to a low frequency treatment device and a pad portion for the low frequency treatment device.
　従来、導電層を有するパッドを使用者の身体に取り付けて、身体に低周波パルス電流を供給することで、使用者の肩こりをほぐす等の治療を行う低周波治療器が存在する（特許文献１参照）。 Conventionally, there is a low-frequency treatment device that attaches a pad having a conductive layer to a user's body and supplies a low-frequency pulse current to the body to perform treatment such as loosening the user's stiff shoulder (Patent Document 1). reference).
　特許文献１に記載の低周波治療器は、ホルダ（特許文献１における「下半部分」）に対し、パッド（同「電極パッド」）を挟んだ状態で本体部（同「上半部分」）が取り付けられる。パッドへの通電は、ホルダに設けられた端子が本体部とパッドとに電気的に接続されることでなされる。つまり、本体部から一旦ホルダを介してパッドへ通電される。 The low-frequency treatment device described in Patent Document 1 has a main body (the “upper half part”) with a pad (the “electrode pad”) sandwiched between the holder (the “lower half part” in Patent Document 1). Is attached. Energization of the pad is performed by electrically connecting a terminal provided on the holder to the main body and the pad. That is, electricity is supplied from the main body to the pad once through the holder.
　このように特許文献１に記載の低周波治療器では、ホルダ、パッド、本体部の３部品を組み立てないと使用できる状態にならない。このため、低周波治療器の使用開始までに要する作業が煩雑であった。 Thus, the low-frequency treatment device described in Patent Document 1 cannot be used unless the holder, the pad, and the main body are assembled. For this reason, the work required to start using the low frequency treatment device is complicated.
　また、特許文献１に記載の低周波治療器では、本体部から一旦ホルダを介してパッドへ通電されるという冗長な通電経路により通電がなされる。このため、前記冗長な通電経路の途中で接続不良が生じる可能性があり、パッドへの通電が不安定となる場合があった。 Moreover, in the low frequency treatment device described in Patent Document 1, energization is performed through a redundant energization path in which the body is once energized to the pad through the holder. For this reason, connection failure may occur in the middle of the redundant energization path, and energization to the pad may become unstable.

　次に、本発明につき、一実施形態を取り上げて説明を行う。なお、以下説明での上下方向は図１に示した状態の低周波治療器１における上下方向である。本実施形態の低周波治療器１は、コードレスタイプである。低周波治療器１は、パッド２１及びホルダ２２が一体とされたパッド部２と本体部３とを備え、パッド部２と本体部３とを組み合わせて治療を行うことができる。なお、前記「一体」とは、通常の使用状態でパッド２１とホルダ２２とが着脱不能に組み合わされた状態をいう。 Next, the present invention will be described by taking one embodiment. In the following description, the vertical direction is the vertical direction of the low frequency treatment device 1 in the state shown in FIG. The low frequency treatment device 1 of the present embodiment is a cordless type. The low-frequency treatment device 1 includes a pad portion 2 and a main body portion 3 in which a pad 21 and a holder 22 are integrated, and can perform treatment by combining the pad portion 2 and the main body portion 3. The term “integrated” refers to a state in which the pad 21 and the holder 22 are detachably combined in a normal use state.
　パッド２１は、使用者の身体に取り付けられるシート状の部分である。このパッド２１は、使用者に低周波パルス電流を供給する導電層２１ａを備える。導電層２１ａは、パッド２１の表裏各面の少なくとも一部に露出している。本実施形態では、パッド２１の身体側を向いた身体側部２１１の面である裏面（下面）における全面と、表面（上面）における一部の面とに、導電層２１ａが露出している。使用者の身体へのパッド２１の取り付けは、身体側部２１１を、図４にハッチングを付して示した面を有する治療部２１Ｙに取り付けられた導電性のゲルを介して、使用者の皮膚に貼り付けることで行う。 The pad 21 is a sheet-like part attached to the user's body. The pad 21 includes a conductive layer 21a that supplies a low-frequency pulse current to the user. The conductive layer 21 a is exposed on at least a part of the front and back surfaces of the pad 21. In the present embodiment, the conductive layer 21a is exposed on the entire surface on the back surface (lower surface), which is the surface of the body side portion 211 facing the body side of the pad 21, and on a part of the surface (upper surface). The pad 21 is attached to the user's body by attaching the body side portion 211 to the skin of the user via a conductive gel attached to the treatment portion 21Y having the surface shown hatched in FIG. It is done by pasting to.
　パッド２１は軟質合成樹脂製の基材（図示しない）の表面に、例えば、印刷により導体であるカーボン層を積層したものであり、このカーボン層が導電層２１ａとなる。パッド２１は、可撓性を有する。導電層２１ａは、通電時の極性（＋極、－極）別に設けられている。なお、パッド２１には極性を交互に転換させて通電することもあるので、＋極専用の導電層２１ａと－極専用の導電層２１ａが固定的に存在するのではなく、極性は可変的である。 The pad 21 is obtained by laminating a carbon layer as a conductor on the surface of a soft synthetic resin base material (not shown), for example, by printing, and this carbon layer becomes the conductive layer 21a. The pad 21 has flexibility. The conductive layer 21a is provided for each polarity (+ pole, -pole) when energized. Since the pad 21 may be energized by alternately changing the polarity, the positive electrode-dedicated conductive layer 21a and the negative electrode-dedicated conductive layer 21a do not exist in a fixed manner, but the polarity is variable. is there.
　パッド２１は、図２に示すように、長軸を有する形状（具体的には、長さ方向の両端が丸みを帯びた略矩形状）のホルダ２２上に取り付けられる取付部２１Ｘと、この取付部２１Ｘから少なくとも任意の一方向に延び導電層２１ａが露出した治療部２１Ｙとを備える。パッド２１は、パッド部２においてホルダ２２の幅方向（すなわち、前記長軸に直交する方向）の両側に延びるように形成される（図３及び図４参照）。本実施形態の治療部２１Ｙは、取付部２１Ｘから極性別に、互いに反対方向に延びている。また、治療部２１Ｙにおける底面である身体側部２１１のうち全表面に導電層２１ａが露出している。 As shown in FIG. 2, the pad 21 includes a mounting portion 21 </ b> X that is mounted on a holder 22 having a shape having a long axis (specifically, a substantially rectangular shape in which both ends in the length direction are rounded), And a treatment part 21Y extending in at least one arbitrary direction from the part 21X and exposing the conductive layer 21a. The pad 21 is formed so as to extend on both sides in the width direction of the holder 22 (that is, the direction orthogonal to the major axis) in the pad portion 2 (see FIGS. 3 and 4). The treatment portion 21Y of the present embodiment extends in the opposite direction from the attachment portion 21X for each polarity. In addition, the conductive layer 21a is exposed on the entire surface of the body side portion 211 that is the bottom surface of the treatment portion 21Y.
　治療部２１Ｙに比べて取付部２１Ｘは絞られた形状である。つまり、取付部２１Ｘの幅寸法は、治療部２１Ｙの幅寸法よりも小さく形成されている。これにより、ホルダ２２及び本体部３を小型にできる。また導電層２１ａは、パッド２１の取付部２１Ｘにおける本体部３を向いた面である表面（上面）にも露出しており、この露出部分がパッド側電極部２１２となる。このパッド側電極部２１２は、本体部側電極部３３との電気的接続のために形成されている。本実施形態では、取付部２１Ｘにおける幅方向（図３における上下方向）の一端に一方の極（例えば＋極）に対応した導電層２１ａが露出し、他端に他方の極（例えば－極）に対応した導電層２１ａが露出している。よって、パッド側電極部２１２の導電層２１ａは、パッド２１の外周部に露出している。パッド側電極部２１２における導電層２１ａの露出は、例えば、導電層２１ａを覆っているパッド２１の層の少なくとも一部分を剥がすこと、裏面に導電層が設けられたパッド２１の少なくとも一部分を表裏折り返すことによって表側に露出した部分を導電層２１ａとすること、導電層が形成された部材をパッド２１に厚み方向に重ね合わせてその導電層を導電層２１ａとすることで実現できる。 The attachment portion 21X has a narrowed shape compared to the treatment portion 21Y. That is, the width dimension of the attachment part 21X is formed smaller than the width dimension of the treatment part 21Y. Thereby, the holder 22 and the main-body part 3 can be reduced in size. The conductive layer 21 a is also exposed on the surface (upper surface) which is the surface facing the main body 3 in the attachment portion 21 </ b> X of the pad 21, and this exposed portion becomes the pad-side electrode portion 212. The pad side electrode portion 212 is formed for electrical connection with the main body portion side electrode portion 33. In the present embodiment, the conductive layer 21a corresponding to one pole (for example, the + pole) is exposed at one end in the width direction (vertical direction in FIG. 3) of the mounting portion 21X, and the other pole (for example, the − pole) at the other end. The conductive layer 21a corresponding to is exposed. Therefore, the conductive layer 21 a of the pad side electrode portion 212 is exposed at the outer peripheral portion of the pad 21. The exposure of the conductive layer 21a in the pad side electrode part 212 is, for example, peeling off at least a part of the layer of the pad 21 covering the conductive layer 21a, or turning back and up at least a part of the pad 21 provided with the conductive layer on the back surface. Thus, the portion exposed to the front side can be made the conductive layer 21a, and the member on which the conductive layer is formed can be superimposed on the pad 21 in the thickness direction to make the conductive layer the conductive layer 21a.
　ホルダ２２はパッド２１を保持する部分である。本実施形態では、ホルダ２２は硬質樹脂製であり、両面粘着テープによりパッド２１の取付部２１Ｘを保持している。これにより、パッド２１とホルダ２２とが一体とされる。このホルダ２２は、パッド２１の取付部２１Ｘを保持するパッド保持部２２１と、パッド保持部２２１の両端に位置する壁部２２２とを備える。なお、パッド２１の保持は両面粘着テープによるものに限定されず、例えば熱溶着によるものや、のりや接着剤によることもできる。 The holder 22 is a part that holds the pad 21. In the present embodiment, the holder 22 is made of hard resin, and holds the attachment portion 21X of the pad 21 with a double-sided adhesive tape. Thereby, the pad 21 and the holder 22 are united. The holder 22 includes a pad holding portion 221 that holds the attachment portion 21 </ b> X of the pad 21, and wall portions 222 that are positioned at both ends of the pad holding portion 221. The holding of the pad 21 is not limited to that using a double-sided pressure-sensitive adhesive tape, and may be, for example, heat sealing, glue, or adhesive.
　ホルダ２２は硬質樹脂製であるから不導体である。このため、パッド２１を使用者の背中において背骨を跨ぐように配置した場合、背骨に不導体であるホルダ２２を一致させ、パッド２１の治療部２１Ｙが背骨に重ならないように配置できる。これにより、使用者の背骨及び脊髄に低周波パルス電流が流れることを抑制できる。よって、背骨及び脊髄が電流により損傷を受けることを抑制できるため、低周波治療器１を安全に使用できる。また、パッド２１の取付部２１Ｘにおいて、背骨に重なる部分を別途絶縁部材で覆う必要がないため、パッド部２の構成を簡素化できる。 Since the holder 22 is made of hard resin, it is non-conductive. For this reason, when the pad 21 is disposed so as to straddle the spine on the back of the user, the holder 22 that is a non-conductor is aligned with the spine, so that the treatment portion 21Y of the pad 21 does not overlap the spine. Thereby, it can suppress that a low frequency pulse current flows into a user's spine and spinal cord. Therefore, since it can suppress that a spine and a spinal cord are damaged by an electric current, the low frequency treatment device 1 can be used safely. Moreover, in the attachment part 21X of the pad 21, since it is not necessary to cover the part which overlaps with a spine with an insulating member separately, the structure of the pad part 2 can be simplified.
　図５Ａに示すように、パッド保持部２２１は、中央寄りに位置するパッド当接部２２１１と、壁部２２２寄りに位置する周縁部２２１２とを有する。図示のように、パッド当接部２２１１の上面よりも周縁部２２１２の上面の方が上方にある。このため、ホルダ２２へ本体部３を取り付けた状態では、周縁部２２１２に本体部３の下面３２が当接する。 As shown in FIG. 5A, the pad holding part 221 has a pad contact part 2211 located closer to the center and a peripheral part 2212 located closer to the wall part 222. As shown in the drawing, the upper surface of the peripheral edge portion 2212 is located higher than the upper surface of the pad contact portion 2211. For this reason, when the main body 3 is attached to the holder 22, the lower surface 32 of the main body 3 comes into contact with the peripheral edge 2212.
　図２に示すように、パッド当接部２２１１の上面に当接するようにしてパッド２１がパッド当接部２２１１に重ねられる。パッド当接部２２１１から上方に略Ｕ字状の位置決め突起２２１３が突出しており、パッド２１において表裏方向に貫通した窓部２１３の縁部を位置決め突起２２１３に合わせることで、ホルダ２２に対するパッド２１の位置決めを行うことができる。 As shown in FIG. 2, the pad 21 is overlaid on the pad contact portion 2211 so as to contact the upper surface of the pad contact portion 2211. A substantially U-shaped positioning projection 2213 protrudes upward from the pad abutting portion 2211. By aligning the edge of the window portion 213 penetrating in the front and back direction in the pad 21 with the positioning projection 2213, the pad 21 with respect to the holder 22 Positioning can be performed.
　前述のように、パッド当接部２２１１の上面よりも周縁部２２１２の上面の方が上方にある。このため、ホルダ２２へと本体部３を取り付けた状態では、周縁部２２１２に本体部３の下面３２が当接するので、図７に示すように、パッド当接部２２１１上のパッド２１の上面と本体部３の下面３２とが密着せず、隙間を有するようにできる。このため、パッド側電極部２１２のカーボン層に下面３２が擦れることで本体部３が剥がれたカーボンにより汚されることを、抑制できる。よって、低周波治療器１を美しく使用することができる。 As described above, the upper surface of the peripheral edge portion 2212 is higher than the upper surface of the pad contact portion 2211. For this reason, when the main body 3 is attached to the holder 22, the lower surface 32 of the main body 3 abuts on the peripheral edge 2212, and therefore, as shown in FIG. The lower surface 32 of the main body 3 is not in close contact, and a gap can be provided. For this reason, it can suppress that the main-body part 3 is soiled by the carbon which the lower surface 32 rubbed against the carbon layer of the pad side electrode part 212. Therefore, the low frequency treatment device 1 can be used beautifully.
　パッド２１は消耗品であるので、交換の際等に、本体部３に対して着脱可能とされている。本実施形態では、ホルダ２２がパッド２１と一体となってパッド部２を構成しており、ホルダ２２に対して本体部３が着脱されるよう構成されている。パッド２１の交換はホルダ２２ごと行われる。 Since the pad 21 is a consumable item, it can be attached to and detached from the main body 3 at the time of replacement. In the present embodiment, the holder 22 is integrated with the pad 21 to constitute the pad portion 2, and the main body portion 3 is configured to be attached to and detached from the holder 22. The replacement of the pad 21 is performed together with the holder 22.
　本体部３は、ホルダ２２に取り付けられることで、パッド２１の導電層２１ａに低周波パルス電流を供給する部分である。本体部３の内部には電池等の電源部、及び、所望の低周波パルス電流を形成するための電気回路（基板）が配置され、外部にはスイッチ類や表示部が設けられている（一部を除き図示しない）。図５Ｂに示すように、本体部３のホルダ２２に正対する面である下面３２からは、本体部側電極部３３がばね３４により付勢された状態で突出している（本体部側電極部３３の位置を図８Ａ及びＢにも二点鎖線で示す）。この本体部側電極部３３は極性別に設けられている。 The main body 3 is a part that supplies a low-frequency pulse current to the conductive layer 21 a of the pad 21 by being attached to the holder 22. A power source unit such as a battery and an electric circuit (substrate) for forming a desired low-frequency pulse current are arranged inside the main body unit 3, and switches and a display unit are provided outside (one Not shown except for the part). As shown in FIG. 5B, the main body portion side electrode portion 33 protrudes from the lower surface 32 which is a surface facing the holder 22 of the main body portion 3 in a state of being biased by the spring 34 (the main body portion side electrode portion 33). Is also indicated by a two-dot chain line in FIGS. 8A and 8B). The main body side electrode part 33 is provided for each polarity.
　ここで、図４に示すように、ホルダ２２が本体部３に係止された状態において、ホルダ２２の幅寸法Ｗ２２は、本体部３の幅寸法Ｗ３よりも小さく形成されている。ホルダ２２は硬質樹脂製であるため、可撓性に乏しい。一方、パッド２１は可撓性を有するため、ホルダ２２を本体部３よりも幅狭とすることにより、パッド２１の可撓性が本体部３によって阻害されにくい。このため、使用者の身体の曲面にパッド２１を沿わせやすいから、パッド部２の使用者の身体へのフィット性が良好である。 Here, as shown in FIG. 4, the width dimension W <b> 22 of the holder 22 is formed smaller than the width dimension W <b> 3 of the main body part 3 in a state where the holder 22 is locked to the main body part 3. Since the holder 22 is made of hard resin, the flexibility is poor. On the other hand, since the pad 21 has flexibility, the flexibility of the pad 21 is not easily disturbed by the main body 3 by making the holder 22 narrower than the main body 3. For this reason, since it is easy to make the pad 21 follow the curved surface of a user's body, the fit property to the user's body of the pad part 2 is favorable.
　ホルダ２２及び本体部３には、ホルダ２２に対して本体部３を重ねて取り付けた状態ではホルダ２２と本体部３とが係合し、取り外した状態ではホルダ２２と本体部３とが係合解除するよう構成された誘導係合部４が形成されている。この誘導係合部４は、ホルダ２２と本体部３との両者を係合すると共に、両者の取り付け及び取り外しの際にホルダ２２に対する本体部３の移動方向を規制する。具体的に、この誘導係合部４は、ホルダ２２と本体部３との両者の取り付けの際には、両者が図２に矢印で示す正対方向（下方向）Ｄ１に移動して係合に至るように形成されている。そして、この誘導係合部４は、ホルダ２２と本体部３との両者の取り外しの際には、ホルダ２２に対して本体部３が前記正対方向Ｄ１に交わる方向（横方向）Ｄ２（図８Ａ参照）に移動することで両者が係合解除されるよう形成されている。なお、この取り外しの際には、前記取り付けの際の移動方向と逆方向（上方向）への移動は抑制されている（本実施形態では移動が不可能とされている）。また、本実施形態では、平面視における反時計回りの方向である方向Ｄ２とは反対の方向である時計回りの方向に本体部３を移動させても、ホルダ２２と本体部３とが係合解除される。このように、横方向の両方向に本体部３を移動させてホルダ２２と本体部３とを係合解除できるように誘導係合部４を構成でき、また、横方向の一方向にのみ本体部３を移動させてホルダ２２と本体部３とを係合解除できるようにも誘導係合部４を構成できる。 The holder 22 and the main body 3 are engaged with the holder 22 and the main body 3 when the main body 3 is attached to the holder 22 in an overlapped manner, and the holder 22 and the main body 3 are engaged with each other when the main body 3 is detached. A guide engagement portion 4 configured to be released is formed. The induction engaging portion 4 engages both the holder 22 and the main body portion 3 and regulates the moving direction of the main body portion 3 with respect to the holder 22 when both are attached and detached. Specifically, when the holder 22 and the main body 3 are attached to each other, the guide engaging portion 4 is engaged by moving both in a directly facing direction (downward) D1 indicated by an arrow in FIG. It is formed to reach. When the holder 22 and the main body 3 are both removed, the guide engaging portion 4 has a direction (lateral direction) D2 in which the main body 3 intersects the holder 22 in the facing direction D1 (see FIG. 8A)) so that both are disengaged. In this removal, the movement in the direction opposite to the movement direction (upward direction) at the time of the attachment is suppressed (movement is impossible in this embodiment). In the present embodiment, the holder 22 and the main body 3 are engaged even if the main body 3 is moved in the clockwise direction that is the direction opposite to the direction D2 that is counterclockwise in plan view. Canceled. In this way, the guide engagement portion 4 can be configured such that the main body 3 can be moved in both lateral directions so that the holder 22 and the main body 3 can be disengaged. The guide engaging portion 4 can also be configured so that the holder 22 and the main body portion 3 can be disengaged by moving 3.
　このように誘導係合部４がホルダ２２に対する本体部３の移動方向を規制することにより、本体部３に対するホルダ２２の取り付けはワンタッチ（ホルダ２２への本体部３の押込みのみ）でできる。一方、取り外しに関しては、ホルダ２２と本体部３とは、前記正対方向Ｄ１に交わる方向（横方向）Ｄ２に移動することで係合解除されるため、使用者の操作以外の外力により係合解除されにくい。そのため、使用中に使用者が動いても、ホルダ２２から本体部３が不意に外れることを抑制できる。特に本実施形態では、後述のストッパー突起４２２１が存在するため、ホルダ２２と本体部３とが更に係合解除されにくくなっている。 As described above, the guide engagement portion 4 regulates the moving direction of the main body 3 with respect to the holder 22, so that the holder 22 can be attached to the main body 3 with one touch (only the main body 3 is pushed into the holder 22). On the other hand, regarding the removal, since the holder 22 and the main body 3 are disengaged by moving in the direction (lateral direction) D2 intersecting the facing direction D1, they are engaged by an external force other than the user's operation. It is hard to be released. Therefore, even if a user moves during use, the main body 3 can be prevented from being unexpectedly detached from the holder 22. In particular, in the present embodiment, since a stopper protrusion 4221 described later exists, the holder 22 and the main body 3 are further unlikely to be disengaged.
　誘導係合部４は、ホルダ２２から本体部３を取り外す際に、例えば図８Ａに矢印で示した横方向Ｄ２に、本体部３をホルダ２２に対して回動させることで、ホルダ２２と本体部３とが係合解除されるよう形成されている。この構成により、取り外しの際は正対方向Ｄ１に対して回動させることにより係合解除されるため、単なる平行移動による係合解除と比べて、使用中に使用者が動いた際にホルダ２２から本体部３が不意に外れることを効果的に抑制できる。 When removing the main body 3 from the holder 22, the guide engagement portion 4 rotates the main body 3 with respect to the holder 22 in the horizontal direction D 2 indicated by an arrow in FIG. The part 3 is formed so as to be disengaged. With this configuration, since the engagement is released by rotating with respect to the facing direction D1 at the time of removal, the holder 22 is moved when the user moves during use as compared with the engagement release by simple translation. It can suppress effectively that the main-body part 3 comes off unexpectedly.
　以下、この誘導係合部４について具体的に説明する。本実施形態における誘導係合部４は、図２に示すように、本体部３に形成された突起である係止部としての本体部側突起４１と、ホルダ２２に形成され本体部側突起４１が嵌る被係止部としての溝部４２とを備える。この構成では、誘導係合部４を凹凸嵌合により構成できるので、その構成を簡素化できる。 Hereinafter, the guide engaging portion 4 will be specifically described. As shown in FIG. 2, the guide engaging portion 4 in the present embodiment includes a main body portion side protrusion 41 as a locking portion that is a protrusion formed on the main body portion 3, and a main body portion side protrusion 41 formed on the holder 22. And a groove portion 42 as a locked portion into which is fitted. In this configuration, since the guide engaging portion 4 can be configured by concave and convex fitting, the configuration can be simplified.
　ホルダ２２における一対の壁部２２２は、パッド保持部２２１の長手方向両端であり、本体部３を正対方向Ｄ１に交わる方向に挟む両側（パッド２１の幅方向（図３における上下方向）両端側）にそれぞれ位置している。この一対の壁部２２２は、取り外しの際における横方向Ｄ２への本体部３の回動を許容するように内側が湾曲形状とされている。個々の壁部２２２の内面には、前記溝部４２として縦溝部４２１と横溝部４２２とが形成されている。縦溝部４２１は、ホルダ２２と本体部３との正対方向Ｄ１である縦方向に形成され、上方が開口している。横溝部４２２は、前記縦方向に交わる横方向に形成され、横方向の少なくとも一方の端部が開口している。本実施形態では縦溝部４２１と横溝部４２２とが直交している。また、本実施形態の横溝部４２２は横方向の両端とも開口している。 The pair of wall portions 222 in the holder 22 are both ends in the longitudinal direction of the pad holding portion 221, and both sides (the width direction of the pad 21 (vertical direction in FIG. 3)) both ends sandwiching the main body portion 3 in the direction crossing the facing direction D1. ) Respectively. The pair of wall portions 222 are curved inward so as to allow the main body portion 3 to rotate in the lateral direction D2 during removal. On the inner surface of each wall portion 222, a vertical groove portion 421 and a horizontal groove portion 422 are formed as the groove portions 42. The vertical groove portion 421 is formed in the vertical direction, which is the facing direction D <b> 1 between the holder 22 and the main body portion 3, and is open upward. The lateral groove portion 422 is formed in a lateral direction intersecting with the longitudinal direction, and at least one end portion in the lateral direction is open. In the present embodiment, the vertical groove portion 421 and the horizontal groove portion 422 are orthogonal to each other. Further, the lateral groove portion 422 of the present embodiment is open at both ends in the lateral direction.
　縦溝部４２１と横溝部４２２とが交わる部分における縦断面形状は、図５Ａに示す形状である。縦溝部４２１は、上部に、内方（パッド保持部２２１の中央方向）に延びる庇部４２３が位置する。庇部４２３の上部には、導入斜面４２３１が形成されている。この導入斜面４２３１は、内方に向かうにつれ下降する、緩やかに湾曲した斜面である。庇部４２３の下部には、水平面４２３２が形成されている。横溝部４２２の上下寸法は、本体部３に形成された本体部側突起４１の上下寸法よりもわずかに大きく形成されている。これにより、本体部側突起４１が横溝部４２２の長手方向に沿って移動可能とされている。また、縦溝部４２１と横溝部４２２とが交わる部分には、横溝部４２２の下面から上方に突出する係合突起４２４が形成されている。 The vertical cross-sectional shape at the portion where the vertical groove portion 421 and the horizontal groove portion 422 intersect is the shape shown in FIG. 5A. The vertical groove portion 421 is provided with a flange portion 423 extending inwardly (in the center direction of the pad holding portion 221) in the upper portion. An introduction slope 4231 is formed on the upper portion of the flange portion 423. The introduction slope 4231 is a gently curved slope that descends inward. A horizontal surface 4232 is formed at the lower portion of the flange portion 423. The vertical dimension of the lateral groove part 422 is formed slightly larger than the vertical dimension of the main body part side projection 41 formed on the main body part 3. Accordingly, the main body side protrusion 41 is movable along the longitudinal direction of the lateral groove portion 422. In addition, an engaging protrusion 424 that protrudes upward from the lower surface of the horizontal groove portion 422 is formed at a portion where the vertical groove portion 421 and the horizontal groove portion 422 intersect.
　そして横溝部４２２には、図６に示すように、ホルダ２２に対して本体部３を重ねて取り付けた状態から、ホルダ２２に対して、例えば横方向Ｄ２に本体部３を回動させることを制限する、制限部としての一対のストッパー突起４２２１，４２２１が形成されている。これら一対のストッパー突起４２２１，４２２１は、取り付け状態において本体部側突起４１を挟む横方向両側に位置している。各ストッパー突起４２２１に対し、移動させられようとする本体部側突起４１は当接する。この当接により、本体部３の係合解除される方向への移動が制限される。本実施形態では、横方向の両方向に本体部３を移動させてホルダ２２と本体部３とを係合解除できるので、ストッパー突起４２２１が２箇所に形成されている。もっとも、横方向の一方向にのみ本体部３を移動させてホルダ２２と本体部３とを係合解除できるよう誘導係合部４を構成した場合には、ストッパー突起４２２１を１箇所にだけ形成すればよい。 Then, as shown in FIG. 6, the main body 3 is rotated, for example, in the horizontal direction D <b> 2 with respect to the holder 22 from the state where the main body 3 is attached to the holder 22 so as to overlap the horizontal groove 422. A pair of stopper protrusions 4221 and 4221 are formed as limiting portions to be limited. The pair of stopper protrusions 4221 and 4221 are located on both sides in the lateral direction with the main body portion side protrusion 41 interposed therebetween in the attached state. The main body side protrusion 41 to be moved comes into contact with each stopper protrusion 4221. This contact restricts the movement of the main body 3 in the direction in which the main body 3 is disengaged. In the present embodiment, the holder 22 and the main body 3 can be disengaged by moving the main body 3 in both lateral directions, so that the stopper protrusions 4221 are formed at two locations. However, when the guide engaging portion 4 is configured so that the main body portion 3 can be moved only in one lateral direction and the holder 22 and the main body portion 3 can be disengaged, the stopper protrusion 4221 is formed only at one location. do it.
　そして、一定の力を超えて本体部３を回動させると、本体部側突起４１がストッパー突起４２２１を乗り越える。すると、前記移動の制限は解除されて、図８Ａに示す横方向Ｄ２に本体部３を回動させることができるようになり、その結果、図８Ｂに示すように、本体部３が係合解除された状態にできる。 Then, when the main body part 3 is rotated beyond a certain force, the main body part side protrusion 41 gets over the stopper protrusion 4221. Then, the restriction on the movement is released, and the main body 3 can be rotated in the lateral direction D2 shown in FIG. 8A. As a result, the main body 3 is disengaged as shown in FIG. 8B. It can be in the state that was made.
　図６に示すように、各ストッパー突起４２２１の内側（本体部側突起４１に面した側）には斜面４２２１ａが形成されている。このため、本体部側突起４１はこの斜面４２２１ａに当接して移動が制限されることになる。よって、過大な力を要さずに本体部側突起４１にストッパー突起４２２１を乗り越えさせて、ホルダ２２と本体部３とを係合解除できる。 As shown in FIG. 6, a slope 4221a is formed inside each stopper projection 4221 (on the side facing the main body portion side projection 41). For this reason, the movement of the main body portion side protrusion 41 is restricted by abutting against the inclined surface 4221a. Therefore, the holder 22 and the main body 3 can be disengaged by causing the main body side protrusion 41 to get over the stopper protrusion 4221 without requiring an excessive force.
　以上、横溝部４２２に一対のストッパー突起４２２１，４２２１が形成されたことで、各ストッパー突起４２２１により本体部３が横方向Ｄ２に回動することを制限できる。このため、係合状態を確実に維持できる。また、前記乗り越えの際には、「カチッ」という音及び触覚（クリック感）が使用者に伝わるため、使用者は本体部３が係合状態でなくなったことを知ることができる。これにより、もし誤って本体部３を回動させた際にも前記クリック感が使用者に伝わるため、回動させたことが誤りの場合は、本体部３を取り付け直すことを使用者に促すことができる。 As described above, since the pair of stopper protrusions 4221 and 4221 are formed in the lateral groove portion 422, the rotation of the main body portion 3 in the lateral direction D2 by each stopper protrusion 4221 can be restricted. For this reason, an engagement state can be maintained reliably. Further, when the user gets over the vehicle, a “click” sound and a tactile sensation (click feeling) are transmitted to the user, so that the user can know that the main body 3 is not engaged. Accordingly, the click feeling is transmitted to the user even if the main body 3 is accidentally rotated, and if the rotation is incorrect, the user is prompted to reattach the main body 3. be able to.
　一方、本体部３は、ホルダ２２の壁部２２２に対向する側面３１に、ホルダ２２の縦溝部４２１に沿った移動と横溝部４２２に沿った移動とが可能な本体部側突起４１が形成されている。この構成によると、取り付ける際、基本的に不動である側であるホルダ２２に縦溝部４２１及び横溝部４２２が設けられ、移動させる側である本体部３に本体部側突起４１が形成されている。よって、両者の位置合わせが容易である。 On the other hand, the main body 3 is formed with a main body side protrusion 41 on the side surface 31 facing the wall portion 222 of the holder 22 so that the holder 22 can move along the vertical groove 421 and move along the horizontal groove 422. ing. According to this configuration, when attaching, the holder 22 which is basically a stationary side is provided with the vertical groove portion 421 and the horizontal groove portion 422, and the main body portion side protrusion 41 is formed on the main body portion 3 which is the moving side. . Therefore, it is easy to align the two.
　本体部側突起４１の縦断面形状を、図５Ｂに示す。本体部側突起４１の上部には水平面４１１が形成されており、下部には水平面４１２及びテーパ面４１３が形成されている。下部の水平面４１２は、ホルダ２２への本体部３の取り付け時に係合突起４２４に当接する。またテーパ面４１３は、下方に向かうにつれ本体部側突起４１の突出量が縮小するような平坦な斜面である。 The vertical cross-sectional shape of the main body side protrusion 41 is shown in FIG. 5B. A horizontal surface 411 is formed on the upper portion of the main body side protrusion 41, and a horizontal surface 412 and a tapered surface 413 are formed on the lower portion. The lower horizontal surface 412 abuts on the engaging protrusion 424 when the main body 3 is attached to the holder 22. Further, the taper surface 413 is a flat slope whose protrusion amount of the main body side protrusion 41 is reduced as it goes downward.
　なお、図２に示すように、本体部側突起４１は側面３１の上下方向中央よりも下方に位置している。このため、本体部側突起４１は上下方向において非対称の位置にある。このため、使用者がもしも本体部３の表裏を間違えてホルダ２２に取り付けようとしても、ホルダ２２側の縦溝部４２１に本体部側突起４１の位置（上下方向の位置）が合わないので取り付けできない。このため、誤装着を抑制できる。 In addition, as shown in FIG. 2, the main body portion side protrusion 41 is located below the center of the side surface 31 in the vertical direction. For this reason, the main body side protrusion 41 is in an asymmetric position in the vertical direction. For this reason, even if the user tries to attach the main body 3 to the holder 22 with the wrong side, the position of the main body side projection 41 (the vertical position) does not match the vertical groove 421 on the holder 22 side. . For this reason, erroneous mounting can be suppressed.
　ホルダ２２への本体部３の取り付けの際には、本体部側突起４１のテーパ面４１３と縦溝部４２１の庇部４２３とが当接する。庇部４２３に本体部側突起４１を一致させて上方から本体部３を押えると、ホルダ２２は樹脂製であるから、本体部側突起４１に押えられた庇部４２３は弾性変形して、庇部４２３の下方、つまり横溝部４２２内に本体部側突起４１が移動する。この結果、本体部側突起４１の下部の水平面４１２が係合突起４２４に当接する。この状態で本体部側突起４１は、庇部４２３の水平面４２３２と係合突起４２４とに挟まれて図７に示す係合状態となる。なお、本体部側突起４１が移動した際、庇部４２３の前記弾性変形が復帰する。この際、「カチッ」という音及び触覚（クリック感）が使用者に伝わるため、使用者は取り付けが正しくなされたことを知ることができる。 When attaching the main body 3 to the holder 22, the tapered surface 413 of the main body side protrusion 41 and the flange 423 of the vertical groove 421 come into contact with each other. When the main body portion side protrusion 41 is aligned with the flange portion 423 and the main body portion 3 is pressed from above, the holder 22 is made of resin, so that the flange portion 423 pressed by the main body portion side protrusion 41 is elastically deformed, The main body side protrusion 41 moves below the portion 423, that is, in the lateral groove portion 422. As a result, the lower horizontal surface 412 of the main body side protrusion 41 abuts on the engagement protrusion 424. In this state, the main body portion side protrusion 41 is sandwiched between the horizontal surface 4232 of the flange portion 423 and the engagement protrusion 424 and is brought into an engagement state shown in FIG. When the main body side protrusion 41 moves, the elastic deformation of the flange portion 423 is restored. At this time, since a “click” sound and a tactile sensation (click feeling) are transmitted to the user, the user can know that the attachment is correctly performed.
　なお、図５Ａ及び図７に示すように、庇部４２３は内方に向かうにつれ上下寸法が小さくなる（剛性が小さくなる）ように形成されている。このため、大きな力で本体部３を下方に押し込まなくても、本体部側突起４１を横溝部４２２内に移動させることができる。 In addition, as shown to FIG. 5A and FIG. 7, the collar part 423 is formed so that an up-down dimension may become small (a rigidity becomes small) as it goes inside. For this reason, the main body side protrusion 41 can be moved into the lateral groove portion 422 without pushing the main body portion 3 downward with a large force.
　この図７に示す係合状態では、本体部側突起４１を上方に移動させようとしても、庇部４２３の水平面４２３２と本体部側突起４１の水平面４１１とが当接するため、移動させることができない。これにより、ホルダ２２に対して本体部３を確実に係合させることができる。 In the engaged state shown in FIG. 7, even if the main body side protrusion 41 is to be moved upward, the horizontal surface 4232 of the flange 423 and the horizontal surface 411 of the main body side protrusion 41 are brought into contact with each other and cannot be moved. . Thereby, the main body 3 can be reliably engaged with the holder 22.
　そして、前記係合状態を解除するには、例えば図８Ａに示すように反時計回りに本体部３を回転させることで、本体部側突起４１を係合突起４２４上から外して横溝部４２２の長手方向に移動させ、図８Ｂに示すように横溝部４２２から脱出させることができる。なお、本実施形態では前記と逆方向の時計回りに回転させても本体部側突起４１を横溝部４２２から脱出させることができる。本体部側突起４１が係合突起４２４上から外れると、係合突起４２４が無くなった分、横溝部４２２において本体部側突起４１を基準とした上下方向寸法に余裕ができるため、本体部３を軽く回転させることができる。図８Ｂに示す状態では前記係合状態が解除されているので、本体部３を上方に移動させることでホルダ２２から本体部３を取り外すことができる。 To release the engagement state, for example, by rotating the main body 3 counterclockwise as shown in FIG. 8A, the main body side protrusion 41 is removed from the engagement protrusion 424 and the lateral groove 422 is removed. It can be moved in the longitudinal direction and escaped from the lateral groove 422 as shown in FIG. 8B. In the present embodiment, the main body side protrusion 41 can be escaped from the lateral groove 422 even if it is rotated clockwise in the opposite direction. When the main body side projection 41 is disengaged from the engagement projection 424, the horizontal groove portion 422 has a margin in the vertical direction with respect to the main body side projection 41 as the engagement projection 424 is eliminated. Can be rotated lightly. Since the engagement state is released in the state shown in FIG. 8B, the main body 3 can be removed from the holder 22 by moving the main body 3 upward.
　ここで、本体部側電極部３３は、図８Ａ及びＢに破線で示すように、本体部側突起４１とは別の位置に備えられている。一方、図２に示すように、パッド２１は取付部２１Ｘにおいて、外周縁２１ｂがホルダ２２における壁部２２２の内縁２２２１に略沿うようにしてホルダ２２に保持されている。本体部側電極部３３は、ホルダ２２に本体部３が取り付けられた状態で、ホルダ２２上に位置するパッド２１のパッド側電極部２１２に当接することで低周波パルス電流を供給する。 Here, the main body part side electrode part 33 is provided at a position different from the main body part side protrusion 41 as shown by broken lines in FIGS. 8A and 8B. On the other hand, as shown in FIG. 2, the pad 21 is held by the holder 22 at the attachment portion 21 </ b> X so that the outer peripheral edge 21 b is substantially along the inner edge 2221 of the wall portion 222 of the holder 22. The main body side electrode section 33 supplies a low-frequency pulse current by contacting the pad side electrode section 212 of the pad 21 located on the holder 22 in a state where the main body section 3 is attached to the holder 22.
　このように、本体部側電極部３３をパッド側電極部２１２に当接した状態で、誘導係合部４によりホルダ２２と本体部３とを係合できる。このため、両電極部の当接を強固にできる。よって、パッド２１と本体部３との導通状態を安定させられる。 As described above, the holder 22 and the main body 3 can be engaged by the induction engaging portion 4 in a state where the main body side electrode portion 33 is in contact with the pad side electrode portion 212. For this reason, the contact of both electrode parts can be strengthened. Therefore, the conduction state between the pad 21 and the main body 3 can be stabilized.
　また、誘導係合部４がホルダ２２と本体部３との物理的接続を担当し、本体部側電極部３３がパッド２１と本体部３との電気的接続を担当する。このため、例えば金属製で凹凸嵌合をなすスナップ部材を用いて嵌合と導通とを兼ねるような、両接続を兼ねた構成に比べて安定した電流の供給が可能である。更に、誘導係合部４と本体部側電極部３３とが近接していることにより、誘導係合部４における係合状態が維持される限りは、本体部側電極部３３とパッド側電極部２１２との当接状態が損なわれにくく、低周波パルス電流を確実に供給できる。 Further, the induction engagement portion 4 is in charge of physical connection between the holder 22 and the main body portion 3, and the main body portion side electrode portion 33 is in charge of electrical connection between the pad 21 and the main body portion 3. For this reason, it is possible to supply a stable current as compared with a configuration in which both connections are made, for example, using a snap member made of metal and having a concavo-convex fitting to serve both fitting and conduction. Furthermore, as long as the induction engagement portion 4 and the main body side electrode portion 33 are close to each other, as long as the engagement state in the induction engagement portion 4 is maintained, the main body side electrode portion 33 and the pad side electrode portion. The contact state with 212 is not easily damaged, and a low-frequency pulse current can be reliably supplied.
　そして、パッド２１は取付部２１Ｘにおいて、外周縁２１ｂに、ホルダ２２における壁部２２２の湾曲に略一致した湾曲部２１４を備える。このように、パッド２１が取り外しの際の回動方向に沿った湾曲形状の外縁を有しているため、取り外しの際にパッド２１が本体部側突起４１等の誘導係合部４に引っ掛かってめくれる事態を抑制でき、そのため低周波治療器１を快適に使用できる。 And the pad 21 is provided with a curved portion 214 that substantially matches the curvature of the wall portion 222 of the holder 22 at the outer peripheral edge 21b of the mounting portion 21X. Thus, since the pad 21 has a curved outer edge along the rotation direction at the time of removal, the pad 21 is caught by the guide engaging portion 4 such as the main body side protrusion 41 at the time of removal. The situation of turning over can be suppressed, so that the low frequency treatment device 1 can be used comfortably.
　以上、本発明の実施形態を説明したが、本発明は前記実施形態に限定されるものではなく、本発明の要旨を逸脱しない範囲内において種々の変更を加えることができる。 As mentioned above, although embodiment of this invention was described, this invention is not limited to the said embodiment, A various change can be added in the range which does not deviate from the summary of this invention.
　前記実施形態のパッド２１は、軟質合成樹脂製の基材の表面に、例えば印刷によりカーボン層を積層したものであり、このカーボン層が導電層２１ａとされていた。しかし、導電層２１ａはこの構成に限定されない。例えば、ある変形形態では、図９Ａ及びＢに示すように、導電層２１ａを表裏一体の一枚の層で形成することもできる。ここで、前記実施形態における導電層２１ａにおいて、基材の表裏にカーボン層を形成した場合、表裏を導通させるためには、表裏のカーボン層を電気的に接続する構成が必要となる。また、一方側の面にカーボン層を形成した上で、このカーボン層の一部を表裏折り返す構成とすることもある。これらの構成では、表裏の電気的な接続部分やカーボン層の折り返し部分に亀裂ができること等により、導通が不安定になる可能性がある。これに対し、この変形形態のパッド２１では、導電層２１ａが表裏一体であるため、前記電気的に接続する構成を要さずに、表裏の導通が安定的になされる点で有利である。 The pad 21 of the above embodiment is obtained by laminating a carbon layer on the surface of a soft synthetic resin base material, for example, by printing, and this carbon layer was used as the conductive layer 21a. However, the conductive layer 21a is not limited to this configuration. For example, in a modification, as shown in FIGS. 9A and 9B, the conductive layer 21a can be formed of a single layer that is integrated with the front and back sides. Here, in the conductive layer 21a in the embodiment, when the carbon layers are formed on the front and back surfaces of the base material, a configuration in which the front and back carbon layers are electrically connected is necessary in order to make the front and back conductive. In addition, a carbon layer may be formed on one surface, and a part of the carbon layer may be turned upside down. In these configurations, there is a possibility that conduction may become unstable due to the occurrence of cracks in the electrically connected portions of the front and back surfaces and the folded portions of the carbon layer. On the other hand, in the pad 21 of this modified embodiment, since the conductive layer 21a is integrated with the front and back, it is advantageous in that conduction between the front and back is made stable without the need for the electrically connecting configuration.
　この変形形態における導電層２１ａは、例えば、繊維シート（紙等）に対し、当該繊維シートを構成する繊維にカーボン粒子等の導電性粒子を付着させることにより形成できる。このように形成されたパッド２１は、繊維シートを構成する繊維の少なくとも表面に、導電性粒子が分散した状態とされている。繊維シートを構成する繊維は、表裏面視にて規則的に（例えば網状に）配置されていてもよいし、不規則に配置されていてもよい。導電層２１ａは、前記繊維シートによるものである他に、樹脂層中に導電性粒子を分散させて形成することもできる。また、単体で導電性を有している繊維を縫製してシート状に形成することもできる。特に、導電層２１ａを繊維シートからなるものとした場合は、パッド２１を柔軟に形成することが可能なため、使用者の身体に沿わせ易い。そのため、使用感を良好とできる点で有利である。なお、導電層２１ａは表裏一体の一枚の層の他に、二枚以上の層が積層してなるものであってもよい。 The conductive layer 21a in this modified embodiment can be formed, for example, by attaching conductive particles such as carbon particles to fibers constituting the fiber sheet (such as paper). The pad 21 formed in this way is in a state in which conductive particles are dispersed on at least the surface of the fibers constituting the fiber sheet. The fibers constituting the fiber sheet may be arranged regularly (for example, in a net shape) as viewed from the front or back, or may be arranged irregularly. In addition to the fiber sheet, the conductive layer 21a can be formed by dispersing conductive particles in the resin layer. Alternatively, a single conductive fiber can be sewn to form a sheet. In particular, when the conductive layer 21a is made of a fiber sheet, the pad 21 can be formed flexibly, so that it is easy to follow the user's body. Therefore, it is advantageous in that the feeling of use can be improved. In addition, the conductive layer 21a may be formed by laminating two or more layers in addition to the single layer of the front and back surfaces.
　この変形形態のパッド２１は、図９Ｂに示すように、表面（上面）については、パッド側電極部２１２以外の部分を非導電性のカバー層２１ｃで覆うことができる。導電層２１ａは極性別に分離されているため、＋極側の導電層２１ａと－極側の導電層２１ａとは、カバー層２１ｃにより物理的に接続される。一方、裏面（下面）については、導電層２１ａの全体を露出させ、治療部２１Ｙに導電性のゲルを取り付けることができる。 As shown in FIG. 9B, the pad 21 of this modification can cover the surface (upper surface) other than the pad-side electrode portion 212 with a non-conductive cover layer 21c. Since the conductive layer 21a is separated according to polarity, the positive electrode side conductive layer 21a and the negative electrode side conductive layer 21a are physically connected by the cover layer 21c. On the other hand, with respect to the back surface (lower surface), the entire conductive layer 21a can be exposed, and a conductive gel can be attached to the treatment portion 21Y.
　また、パッド２１は極性別に分離して形成されていてもよい。また、前記実施形態では、本体部側電極部３３との電気的接続のために形成されている導電層２１ａの露出部分が、取付部２１Ｘにおける幅方向の両端に位置していた。しかし、該露出部分はこれに限定されず、取り付け時の本体部３と重なる限り、幅方向中央等の他の位置であってもよい。また、前記実施形態とは逆に、ホルダ２２に突起が形成され、本体部３に溝部が形成されていてもよい。 Further, the pads 21 may be formed separately for each polarity. Moreover, in the said embodiment, the exposed part of the conductive layer 21a formed for the electrical connection with the main-body part side electrode part 33 was located in the both ends of the width direction in the attaching part 21X. However, the exposed portion is not limited to this, and may be another position such as the center in the width direction as long as it overlaps the main body 3 at the time of attachment. Contrary to the above-described embodiment, the holder 22 may have a protrusion and the main body 3 may have a groove.
　また、前記実施形態の誘導係合部４は、ホルダ２２におけるパッド保持部２２１の長手方向両端に位置する壁部２２２（溝部４２）と、本体部３においてホルダ２２の壁部２２２に対向する側面３１（本体部側突起４１）とに亘って形成されていた。しかし、誘導係合部４はこれに限定されず、他の位置に形成されていてもよい。 In addition, the guide engaging portion 4 of the above embodiment includes a wall portion 222 (groove portion 42) located at both ends in the longitudinal direction of the pad holding portion 221 in the holder 22, and a side surface facing the wall portion 222 of the holder 22 in the main body portion 3. 31 (main body part side protrusion 41). However, the guide engagement portion 4 is not limited to this, and may be formed at other positions.
