Description

本発明は、施療子を有するアームブロックを駆動させてマッサージを行うマッサージ機に関するものである。   The present invention relates to a massage machine that performs massage by driving an arm block having a treatment element.

従来から、施療子を有するアームブロックを駆動させることで被施療者に叩き等の各種マッサージを行うマッサージ機が知られている（例えば引用文献１参照）。   2. Description of the Related Art Conventionally, there is known a massage machine that performs various massages such as hitting a user by driving an arm block having a treatment element (see, for example, cited document 1).

上記マッサージ機は叩き機構として、偏心回転駆動される叩きクランク軸と、アームブロックと叩きクランク軸とを連結させてアームブロックに叩き動作を行わせるリンク部とを具備する構造であり、リンク部と叩きクランク軸との間の摩擦によって施療子が円滑に叩き駆動されなくなるという弊害を防止するために、叩きクランク軸にグリスを塗布しておくことが通常である。   The massage machine has a structure including a hitting crankshaft driven eccentrically as a hitting mechanism, and a link part that connects the arm block and the hitting crankshaft to cause the arm block to perform a hitting operation. In order to prevent the adverse effect that the treatment element is not smoothly driven and driven by friction with the hitting crankshaft, it is usual to apply grease to the hitting crankshaft.

そして上記弊害を更に確実に防止する対策としては、叩きクランク軸の表面粗さやこれに塗布するグリスの種類を適宜設定することで、叩きクランク軸とリンク部との間の摩擦力を低下させることが行われていたが、やはり充分な対策とは言えないものであった。
特開２００４−２２９７６０号公報 And as a measure to further prevent the above-mentioned adverse effects, the frictional force between the hitting crankshaft and the link portion can be reduced by appropriately setting the surface roughness of the hitting crankshaft and the type of grease applied thereto. However, it was still not a sufficient measure.
JP 2004-229760 A

本発明は上記問題点に鑑みて発明したものであって、リンク部と叩きクランク軸との間の摩擦を確実に且つ長期的に低減させることで、快適な叩き性能を発揮することのできるマッサージ機を提供することを課題とするものである。   The present invention has been invented in view of the above-mentioned problems, and a massage capable of exerting a comfortable hitting performance by reliably reducing the friction between the link portion and the hitting crankshaft in the long term. It is an object to provide a machine.

上記課題を解決するために本発明を、施療子を有するアームブロックと、偏心回転駆動される叩きクランク軸と、アームブロックと叩きクランク軸とを連結させてアームブロックに叩き動作を行わせるリンク部とを具備するマッサージ機であって、上記リンク部の叩きクランク軸が嵌入する筒型連結体は、軸方向の端部を除く主体部の内周面に軸受を配したものであり、この筒型連結体の端部内周面を、段部を介して大径に形成するとともに、筒型連結体の端部に装着されて該段部との間でグリス保持部材を保持するホルダを備え、上記ホルダは、叩きクランク軸が貫通する貫通孔を中央に有するリング状の部材であり、フェルト或いは含油フェルトから成るリング状のグリス保持部材を内周面に圧入したうえでその外周面を筒型連結体の端部内周面に圧入することで、グリス保持部材を叩きクランク軸と接触するように保持したものとする。 In order to solve the above-mentioned problems, the present invention has been developed by using an arm block having a treatment element, a hitting crankshaft that is driven to rotate eccentrically, and a link portion that connects the arm block and the hitting crankshaft to cause the arm block to perform a hitting operation. The cylindrical connecting body into which the hitting crankshaft of the link part is fitted is provided with a bearing on the inner peripheral surface of the main part excluding the end part in the axial direction. The inner peripheral surface of the end portion of the mold coupling body is formed with a large diameter via the step portion, and includes a holder that is attached to the end portion of the cylindrical coupling body and holds the grease holding member between the step portion, The holder is a ring-shaped member having a through-hole through which the hitting crankshaft penetrates, and a ring-shaped grease holding member made of felt or oil-impregnated felt is press-fitted into the inner peripheral surface, and the outer peripheral surface is cylindrical End of connected body By press-fitting the inner peripheral surface, and those held in contact with the crankshaft tapping grease holding member.

このような構成とすることで、叩きクランク軸に付着させてあるグリスが上記筒型連結体内のグリス保持部材に保持され、グリスの安定潤滑が長期的に維持されることとなる。したがって、リンク部と叩きクランク軸との間の摩擦を確実に且つ長期的に低減させ、快適な叩き性能を発揮させることが可能である。また、グリス保持部材を筒型連結体内に組み込む作業が容易となり、組立性が向上するものである。 By adopting such a configuration, the grease attached to the hitting crankshaft is held by the grease holding member in the cylindrical connecting body, and stable lubrication of the grease is maintained for a long time. Therefore, it is possible to reliably reduce the friction between the link portion and the hitting crankshaft in the long term and to exhibit a comfortable hitting performance. In addition, the work for incorporating the grease holding member into the cylindrical connector is facilitated, and the assemblability is improved.

更に、上記段部を筒型連結体の両端側に形成するとともに上記ホルダを両端側に備えることで、筒型連結体の両端部にグリス保持部材を組み込むことも好適である。このようにすることで、グリス切れを更に確実に防止して、グリスの安定潤滑を長期的に維持することが可能である。   Furthermore, it is also preferable to incorporate a grease holding member at both ends of the cylindrical connector by forming the stepped portions at both ends of the cylindrical connector and providing the holders at both ends. By doing in this way, it is possible to prevent grease breakage more reliably and maintain stable lubrication of the grease for a long period of time.

また、グリス保持部材の内周面に切欠を設けることも好適である。このようにすることでグリス保持部材の寸法のばらつきを上記切欠に吸収させ、このグリス保持部材と叩きクランク軸とを一定圧力で接触させることが可能となる。   It is also preferable to provide a notch on the inner peripheral surface of the grease holding member. By doing so, it is possible to absorb the variation in the dimensions of the grease holding member in the notch and to bring the grease holding member and the hitting crankshaft into contact with each other at a constant pressure.

本発明は、リンク部と叩きクランク軸との間の摩擦を確実に且つ長期的に低減させることで、快適な叩き性能を発揮することができるという効果を奏する。また、グリス保持部材を筒型連結体内に組み込む作業が容易となり、組立性が向上するという効果を奏する。 INDUSTRIAL APPLICABILITY According to the present invention, it is possible to exert a comfortable hitting performance by reliably and long-term reducing friction between the link portion and the hitting crankshaft. In addition, the work for incorporating the grease holding member into the cylindrical connector is facilitated, and the assemblability is improved.

以下、本発明を添付図面に示す実施形態に基いて説明する。図７には、本発明の実施形態における一例のマッサージ機を示している。本例のマッサージ機は椅子式マッサージ機であって、左右一対のアームブロック１を組み込んである可動ユニット２（図４〜図６参照）を背凭れ部９０内にて上下方向に走行駆動させるとともに、可動ユニット２内に組み込んであるアームブロック１を左右方向の軸中心に回動させることで該アームブロック１が有する施療子１ａ，１ｂの前方への突出量を変化させ、更に、アームブロック１が有する上記施療子１ａ，１ｂの左右方向位置を変更させるものである。そして施療子１ａ，１ｂの上記３方向の位置変更動作を組み合わせることで、所要の動作軌跡を施療子１ａ，１ｂに描かせることが可能である。   Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. FIG. 7 shows an example of a massage machine according to an embodiment of the present invention. The massage machine of this example is a chair type massage machine, and the movable unit 2 (see FIGS. 4 to 6) incorporating a pair of left and right arm blocks 1 is driven to run vertically in the backrest 90. The arm block 1 incorporated in the movable unit 2 is rotated about the axis in the left-right direction to change the amount of protrusion of the treatment elements 1a, 1b of the arm block 1 forward. The position of the treatment elements 1a, 1b of the left and right direction is changed. Then, by combining the above-described three-direction position changing operations of the treatment elements 1a and 1b, it is possible to cause the treatment elements 1a and 1b to draw a required movement locus.

図４〜図６には可動ユニット２を示している。可動ユニット２は、左右一対のギアプレート（図示せず）間に幅送りねじ３１、一対のスライド軸３２、叩きクランク軸４１を架設するとともに、アームブロック１（図中には一方のアームブロック１のみを示している）を左右一対取り付けたものある。可動ユニット２における一方のギアプレート上には、叩き駆動用モータ（図示せず）が取り付けられており、この叩き駆動用モータの出力がプーリやベルト（図示せず）を介して上記叩きクランク軸４１にまで伝達されてこれを偏心回転駆動する構造である。なお、上記叩きクランク軸４１は左右で偏心方向を相違させている。   4 to 6 show the movable unit 2. The movable unit 2 has a width feed screw 31, a pair of slide shafts 32, and a striking crank shaft 41 installed between a pair of left and right gear plates (not shown) and an arm block 1 (one arm block 1 in the figure). Only a pair of left and right are shown. A tapping drive motor (not shown) is mounted on one gear plate of the movable unit 2, and the output of the tapping drive motor is transmitted through the pulley and belt (not shown) to the above tapping crankshaft. It is the structure which is transmitted to 41 and drives this eccentrically. The hitting crankshaft 41 has different eccentric directions on the left and right.

アームブロック１は、施療子支持部材としてのアームベースプレート１０と、叩き板１１、第１アーム１３、第２アーム１４、ローラ型の上下一対の施療子１ａ，１ｂ等から成るもので、アームベースプレート１０は上記幅送りねじ３１のねじ部に螺合する送りナット部３３と、上記各スライド軸３２とスライド自在に嵌合する一対のスライダー３４とを備えて、幅送りねじ３１の回転駆動に伴って幅送りねじ３１及びスライド軸３２上の軸方向位置を変化させる。そして、幅送りねじ３１のねじ部は片側が逆ねじで形成されていることから、左右一対のアームブロック１における各アームベースプレート１０は、幅送りねじ３１の回転によって、互いに接近したり離れたりするものである。   The arm block 1 includes an arm base plate 10 as a treatment element support member, a striking plate 11, a first arm 13, a second arm 14, a pair of upper and lower treatment elements 1a, 1b, and the like. Includes a feed nut portion 33 that is screwed into a thread portion of the width feed screw 31 and a pair of sliders 34 that are slidably fitted to the slide shafts 32. The axial position on the width feed screw 31 and the slide shaft 32 is changed. Since the thread portion of the width feed screw 31 is formed with a reverse screw on one side, the arm base plates 10 in the pair of left and right arm blocks 1 move toward and away from each other as the width feed screw 31 rotates. Is.

上記叩き板１１は支軸Ｎにてアームベースプレート１０に軸着され、叩き板１１に第１アーム１３と第２アーム１４とが支軸Ｋによって軸着されている。また、叩き板１１に設けた支軸Ｍと叩きクランク軸４１とが、リンク部４５によって連結されている。なお、対をなす他方のアームブロック１は図示のアームブロック１の対称形となっている。   The hitting plate 11 is pivotally attached to the arm base plate 10 by a support shaft N, and a first arm 13 and a second arm 14 are attached to the hitting plate 11 by a support shaft K. Further, the support shaft M provided on the hitting plate 11 and the hitting crankshaft 41 are connected by a link portion 45. In addition, the other arm block 1 which makes a pair is a symmetrical form of the illustrated arm block 1.

上下に並ぶ一対の施療子１ａ，１ｂ間の距離を変更させる施療子間隔駆動部は、エアによって伸縮動作を行うエアバッグＡ１で構成されている。このエアバックＡ１は、一方の受け板２０が第１アーム１３に、他方の受け板２０が第２アーム１４に夫々固定されている。更にアームブロック１には、上記エアバックＡ１と同様の構造から成るエアバックＡ２（図中の想像線）を、その一方の受け板２０を叩き駆動用のリンク部４５上に固定するとともに、他方の受け板２０を第１アーム１３に固定させて設けている。   The treatment element interval drive unit that changes the distance between the pair of treatment elements 1a and 1b arranged in the vertical direction is configured by an airbag A1 that performs expansion and contraction operation by air. In the airbag A1, one receiving plate 20 is fixed to the first arm 13, and the other receiving plate 20 is fixed to the second arm 14. Further, an airbag A2 (imaginary line in the figure) having the same structure as the airbag A1 is fixed to the arm block 1 by hitting one receiving plate 20 on the link portion 45 for driving and the other. The receiving plate 20 is fixed to the first arm 13.

次に、上記構成の椅子式マッサージ機内の可動ユニット２の動作について説明する。まず、可動ユニット２と一体に備えてある幅駆動用モータによって幅送りねじ３１を回転駆動させると、前述のように左右一対のアームブロック１，１は幅方向（左右方向）において接近離反し、可動ユニット２内の左右の施療子１ａ，１ｂの間隔を変更する。   Next, operation | movement of the movable unit 2 in the chair type massage machine of the said structure is demonstrated. First, when the width feed screw 31 is rotationally driven by a width driving motor provided integrally with the movable unit 2, as described above, the pair of left and right arm blocks 1 and 1 approach and separate in the width direction (left and right direction), The interval between the left and right treatment elements 1a and 1b in the movable unit 2 is changed.

そして、同じく可動ユニット２と一体に備えてある叩き駆動用モータ（図示せず）で叩きクランク軸４１を回転駆動させると、リンク部４５が叩き板１１を支軸Ｎを中心として前後方向に揺動させ、叩き板１１にアーム１３，１４を介して取り付けられた施療子１ａ，１ｂは、前後に細かく動く叩き動作を行うこととなる。   When the hitting crankshaft 41 is driven to rotate by a hitting drive motor (not shown) that is also provided integrally with the movable unit 2, the link portion 45 swings the hitting plate 11 about the support shaft N in the front-rear direction. The treatment elements 1a and 1b that are moved and attached to the hitting plate 11 via the arms 13 and 14 perform the hitting operation that moves back and forth finely.

また、エアバックＡ１を伸張させたならば、アームブロック１の第２アーム１４が支軸Ｋを中心に回動することで各アーム１３，１４に設けられた施療子１ａ，１ｂは相互に接近する。逆に施療子１ａ，１ｂを近接した状態から相互に離間させる場合には、エアバッグＡ１を排気させればよい。   If the airbag A1 is extended, the second arm 14 of the arm block 1 rotates about the support shaft K, so that the treatment elements 1a and 1b provided on the arms 13 and 14 approach each other. To do. On the contrary, when the treatment elements 1a and 1b are separated from each other from the close state, the airbag A1 may be exhausted.

エアバックＡ２を伸張させたならば、アームブロック１における第１アーム１３と第２アーム１４との叩き板１１を介して揺動自在な範囲が実質的に狭められるものであり、エアバックＡ２を最も伸張させた時には上記揺動の範囲が実質的に略ゼロとなり、近接する施療子１ａ，１ｂによる掴み動作時にあってはより確実な掴みマッサージを得ることができる。   If the airbag A2 is extended, the swingable range of the arm block 1 through the striking plate 11 between the first arm 13 and the second arm 14 is substantially narrowed. When it is extended most, the range of the swing is substantially zero, and a more reliable gripping massage can be obtained during the gripping operation by the adjacent treatment elements 1a and 1b.

次に、上記構成のマッサージ機のリンク部４５について図１〜図３に基づいて詳述する。リンク部４５は、叩きクランク軸４１が嵌入するように両端の開口した筒型に形成してある筒型連結体５０と、叩き板１１の支軸Ｍが嵌入する連結孔５１を貫設してある支軸連結体５２と、両連結体５０，５２を繋ぐ支持体５３とを一体に形成したものである。   Next, the link part 45 of the massage machine of the said structure is explained in full detail based on FIGS. The link part 45 penetrates through a cylindrical connecting body 50 formed in a cylindrical shape opened at both ends so that the hitting crankshaft 41 is inserted, and a connecting hole 51 into which the support shaft M of the hitting plate 11 is inserted. A certain spindle connection body 52 and a support body 53 that connects both the connection bodies 50 and 52 are integrally formed.

上記筒型連結体５０は、その軸方向の両端部Ｅ１，Ｅ２を除く主体部Ｅ３の内周面６０に軸受５４を配するとともに、この主体部Ｅ３の内周面６０と両端部Ｅ１，Ｅ２の内周面６１との間に段部５５を形成し、両端部Ｅ１，Ｅ２の内周面６１が主体部Ｅ３の内周面６０よりも大径となるように設けている。   The cylindrical connector 50 has a bearing 54 disposed on the inner peripheral surface 60 of the main portion E3 excluding both end portions E1 and E2 in the axial direction, and the inner peripheral surface 60 and both end portions E1 and E2 of the main portion E3. A step portion 55 is formed between the inner peripheral surface 61 and the inner peripheral surface 61 of both end portions E1 and E2 so as to have a larger diameter than the inner peripheral surface 60 of the main portion E3.

そして上記筒型連結体５０の両端部Ｅ１，Ｅ２には、それぞれの軸方向外側からホルダ７０が装着されるようになっている。上記ホルダ７０は、叩きクランク軸４１が貫通する貫通孔７１を中央に有するリング状の部材であって、その内周面にリング状を成すグリス保持部材８０を圧入させたうえで、その外周面を筒型連結体５０の端部Ｅ１（Ｅ２）の内周面６１に軸方向外側から圧入させるようになっている。上記ホルダ７０の軸方向外側の端部からは、径方向の内側及び外側に向けて鍔部７２を延設させており、ホルダ７０及びグリス保持部材８０を上記の如く圧入した状態で、筒型連結体５０の段部５５とホルダ７０の鍔部７２との間にグリス保持部材８０が挟持状態で保持されるとともに、このグリス保持部材８０の内周面が、筒型連結体５０内に嵌入される叩きクランク軸４１の外表面と接触するように保持されるものである。   And the holder 70 is attached to both ends E1, E2 of the said cylindrical connection body 50 from each axial direction outer side. The holder 70 is a ring-shaped member having a through-hole 71 in the center through which the hitting crankshaft 41 passes, and a ring-shaped grease holding member 80 is press-fitted into the inner peripheral surface thereof, and then the outer peripheral surface thereof. Is press-fitted into the inner peripheral surface 61 of the end E1 (E2) of the cylindrical connector 50 from the outside in the axial direction. From the axially outer end of the holder 70, a flange 72 is extended inward and outward in the radial direction. With the holder 70 and the grease holding member 80 press-fitted as described above, a cylindrical shape The grease holding member 80 is held between the step portion 55 of the connecting body 50 and the flange portion 72 of the holder 70, and the inner peripheral surface of the grease holding member 80 is fitted into the tubular connecting body 50. It is held so as to be in contact with the outer surface of the hitting crankshaft 41.

上記グリス保持部材８０はフェルト或いは含油フェルトから成る部材であり、叩きクランク軸４１の外表面に付着させてあるグリスをこのグリス保持部材８０内にて保持することで、該グリスによる安定潤滑が長期的に維持される。即ち上記グリス保持部材８０は、リンク部４５と叩きクランク軸４１との間の摩擦を確実に且つ長期的に低減させ、これにより快適な叩きマッサージを可能とするものである。   The grease holding member 80 is a member made of felt or oil-impregnated felt. By holding the grease attached to the outer surface of the hitting crankshaft 41 in the grease holding member 80, stable lubrication by the grease can be performed for a long time. Maintained. That is, the grease holding member 80 reliably and long-term reduces friction between the link portion 45 and the hitting crankshaft 41, thereby enabling a comfortable hitting massage.

なお上記の如く、筒型連結体５０の段部５５を両端側に形成するとともに上記ホルダ７０を両端側に装着させ、グリス保持部材８０を筒型連結体５０の両端部Ｅ１，Ｅ２に組み込む構造としてあるので、リンク部４５の筒型連結体５０とこれを貫通する叩きクランク軸４１との間グリスは、更に安定的に維持されるようになっている。   As described above, the stepped portion 55 of the cylindrical connector 50 is formed on both ends, the holder 70 is mounted on both ends, and the grease holding member 80 is incorporated in both ends E1 and E2 of the cylindrical connector 50. Therefore, the grease between the cylindrical connecting body 50 of the link portion 45 and the hitting crankshaft 41 penetrating therethrough is more stably maintained.

またリング状を成すグリス保持部材８０の内周面には、図３に示すような切欠８１を周方向に等間隔を隔てた複数箇所（図示例では３箇所）に凹設している。この切欠８１により、ホルダ７０の内周面に圧入されるグリス保持部材８０の径方向寸法のばらつきを吸収し、叩きクランク軸４１の外表面にグリス保持部材８０が全面に亘り一定圧力で接触することを可能としている。   Further, on the inner peripheral surface of the ring-shaped grease holding member 80, notches 81 as shown in FIG. 3 are recessed at a plurality of locations (three locations in the illustrated example) at equal intervals in the circumferential direction. This notch 81 absorbs the variation in the radial dimension of the grease holding member 80 that is press-fitted into the inner peripheral surface of the holder 70, and the grease holding member 80 contacts the entire outer surface of the hitting crankshaft 41 at a constant pressure. Making it possible.

更に本例のマッサージ機にあっては、上記筒型連結体５０と同様のグリス保持部材（図示せず）を、スライド軸３２が嵌入されるスライダー３４内にも同様の構造により組み込んでいる。即ち、上記スライダー３４は両端の貫通した筒型を成すものであり、スライダー３４内に組み込まれるグリス保持部材がスライド軸３２の外表面と常時接触することで、スライド軸３２の外表面に付着させてあるグリスをこのグリス保持部材に保持させ、該グリスによる安定潤滑を長期的に維持するものである。   Further, in the massage machine of the present example, a grease holding member (not shown) similar to that of the cylindrical connector 50 is also incorporated in the slider 34 into which the slide shaft 32 is inserted by the same structure. That is, the slider 34 has a cylindrical shape penetrating both ends, and the grease holding member incorporated in the slider 34 is always in contact with the outer surface of the slide shaft 32 so that it adheres to the outer surface of the slide shaft 32. The grease is held by the grease holding member, and stable lubrication by the grease is maintained for a long time.

なお、本発明は上記構成のマッサージ機に限定されるものではなく、アームブロック１やリンク部４５、叩きクランク軸４１等の各構成が本発明の主旨を逸脱しない範囲内で適宜設計変更可能であることは勿論である。   In addition, this invention is not limited to the massage machine of the said structure, Each design, such as the arm block 1, the link part 45, and the striking crankshaft 41, can change a design suitably in the range which does not deviate from the main point of this invention. Of course there is.
