円筒部２５ａの内側面における軸方向端部側は、第２ケース部材３２の外表面から幅方向内側に突出する延出部３２ｆの係合凸部３２ｇが係合する略四角形状の係合孔２５ｃが形成されている。そして、この係合凸部３２ｇと係合孔２５ｃとが回転方向で係合するため、固定部材２５の回り止めがなされている。
The fixing member 25 is formed in a substantially cylindrical shape, and includes a cylindrical portion 25a having a substantially constant outer diameter, and a diameter-enlarging portion 25b whose outer diameter is increased on the axial end portion side of the cylindrical portion 25a. And
The axial end portion side of the inner side surface of the cylindrical portion 25a is a substantially rectangular engagement hole into which the engagement convex portion 32g of the extension portion 32f protruding from the outer surface of the second case member 32 to the inner side in the width direction is engaged. 25c is formed. And since this engagement convex part 32g and the engagement hole 25c engage in a rotation direction, the rotation of the fixing member 25 is made | formed.
また、固定部材２５を構成する円筒部２５ａの外周面には２つの軸受２４ａ，２４ｂにて回転可能に支持される１つの弾性部材から構成される揉み玉２４が設けられている。このため、従来のように複数の部材で構成した分割タイプの揉み玉と比較して、本参考例の揉み玉２４は１つの部材で構成されるため、揉み玉としての剛性及びその耐久性を高くすることができる。 Further, on the outer peripheral surface of the cylindrical portion 25a constituting the fixing member 25, there is provided a kneading ball 24 constituted by one elastic member that is rotatably supported by two bearings 24a and 24b. For this reason, since the kneading balls 24 of this reference example are made of a single member as compared to the conventional split type kneading balls made up of a plurality of members, the rigidity and durability of the kneading balls can be reduced. Can be high.
また、揉み玉２４は、第２ケース部材３２の延出部３２ｆの軸中心から同ケース部材３２の当接部３２ｄまでの距離より僅かに（３ｍｍ程度）大きい半径となるように構成されている。このため、揉み玉２４が使用者の身体とカバー部１３ｂを介して当接する際に、揉み玉２４が接触圧によって変形し、剛体で構成される第２ケース部材３２の当接部３２ｄが使用者に対して軽接触し、極力熱のみを好適に伝達させる構成となっている。また、熱伝達手段を構成する第２ケース部材３２にて弾性部材で構成される揉み玉２４の変形量を所望の範囲に抑えることができるため、揉み玉２４の長寿命化に寄与できる。 Further, the kneading balls 24 are configured to have a radius slightly larger (about 3 mm) than the distance from the axial center of the extending portion 32 f of the second case member 32 to the contact portion 32 d of the case member 32. . For this reason, when the kneading balls 24 abut on the user's body via the cover portion 13b, the kneading balls 24 are deformed by the contact pressure, and the abutting portion 32d of the second case member 32 made of a rigid body is used. It is configured such that only light is suitably transmitted as much as possible. Moreover, since the deformation amount of the kneading balls 24 made of an elastic member can be suppressed to a desired range in the second case member 32 constituting the heat transfer means, it is possible to contribute to the extension of the life of the kneading balls 24.
また、軸受２４ａ，２４ｂは断熱性を有する材料にて構成されているため、弾性部材から構成される揉み玉２４への熱の伝達が抑制されている。
次に、ヒータユニット２３の温度制御及びそれと並行動作される揉み玉２４による施療動作について図５〜図８を用いて説明する。
Further, since the bearings 24a and 24b are made of a heat insulating material, heat transfer to the kneading balls 24 made of an elastic member is suppressed.
Next, the temperature control of the heater unit 23 and the treatment operation by the kneading balls 24 operated in parallel with the temperature control will be described with reference to FIGS.
制御部４０は、図示しない電源スイッチがオン状態に動作され、例えば温熱施療を含むマッサージコースが操作器にて選択されると、マッサージ機構２０の前記モータを駆動させるとともに、最大出力温度ＴｍａｘのＰＴＣヒータ３０に所定の電流Ａ１を印加する。そして、制御部４０は、温度センサ４２にてＰＴＣヒータ３０の熱が伝達させる第２ケース部材３２の温度を監視し、その温度が上限温度Ｔ１を超えると、電流Ａ１よりも電流値の小さい所定の電流Ａ２をＰＴＣヒータ３０に印加する。そして、制御部４０は、ＰＴＣヒータ３０及び熱伝達手段としての第１及び第２ケース部材３１，３２で構成されるヒータユニット２３が上限温度Ｔ１及び下限温度Ｔ２の範囲内に収まるように温度制御するようになっている。これと並行して、例えば首を中心とした揉み玉２４による施療を行う場合、制御部４０は、図７（ａ）（ｂ）に示すように、マッサージ機構２０のモータを制御して使用者の首の位置までマッサージ機構２０を移動させ、モータにてアームを幅方向に動作させて一対の揉み玉２４による挟み動作を行い、使用者の首の施療を行う。この時、揉み玉２４よりも幅方向内側に突出する固定部材２５が使用者の首とカバー部１３ｂを介して当接し、首に対してＰＴＣヒータ３０からの熱を伝達することができるようになっている。 When the power switch (not shown) is turned on, for example, when a massage course including thermal treatment is selected by the operating device, the control unit 40 drives the motor of the massage mechanism 20 and also performs PTC with the maximum output temperature Tmax. A predetermined current A1 is applied to the heater 30. And the control part 40 monitors the temperature of the 2nd case member 32 which the heat | fever of the PTC heater 30 transmits with the temperature sensor 42, and when the temperature exceeds upper limit temperature T1, predetermined value whose electric current value is smaller than electric current A1. Is applied to the PTC heater 30. The control unit 40 controls the temperature so that the heater unit 23 composed of the PTC heater 30 and the first and second case members 31 and 32 as heat transfer means is within the range of the upper limit temperature T1 and the lower limit temperature T2. It is supposed to be. In parallel with this, for example, when performing treatment with the kneading balls 24 around the neck, the control unit 40 controls the motor of the massage mechanism 20 as shown in FIGS. 7 (a) and 7 (b). The massaging mechanism 20 is moved to the position of the neck, the arm is moved in the width direction by a motor, and the pinching operation by the pair of kneading balls 24 is performed to treat the user's neck. At this time, the fixing member 25 protruding inward in the width direction with respect to the kneading balls 24 comes into contact with the user's neck via the cover portion 13b so that heat from the PTC heater 30 can be transmitted to the neck. It has become.
また、前述のヒータユニット２３の温度制御と並行して、使用者の背中を中心として揉み玉２４による施療を行う場合、制御部４０は、図８（ａ）（ｂ）に示すように、マッサージ機構２０のモータを制御して使用者の背中の位置までマッサージ機構２０を移動させ、モータにてアームを上下・左右（幅方向）・前後に動作させて一対の揉み玉２４による押圧動作等を行い、使用者の背中の施療を行う。このとき、揉み玉２４が弾性変形することで熱伝達手段としてのヒータユニット２３（図２及び図３に示す第２ケース部材３２の当接部３２ｄ）が使用者の背中とカバー部１３ｂを介して当接し、使用者の背中に対してＰＴＣヒータ３０からの熱を伝達することができるようになっている。 Further, when performing treatment with the kneading balls 24 around the user's back in parallel with the temperature control of the heater unit 23 described above, the control unit 40 performs massage as shown in FIGS. 8 (a) and 8 (b). The massage mechanism 20 is moved to the position of the user's back by controlling the motor of the mechanism 20, and the arm is moved up and down, left and right (width direction), and front and back by the motor, and the pressing operation by the pair of kneading balls 24 is performed. And perform treatment on the back of the user. At this time, the kneading balls 24 are elastically deformed so that the heater unit 23 (the contact portion 32d of the second case member 32 shown in FIGS. 2 and 3) as a heat transfer means is interposed between the user's back and the cover portion 13b. The heat from the PTC heater 30 can be transmitted to the back of the user.
上述したように、熱伝達手段としてのヒータユニット２３及び固定部材２５とで使用者の身体に熱を伝達することができるため、従来のマッサージ機と比較して使用者に熱を付与する範囲が広がり、熱源としてのＰＴＣヒータ３０からの熱を好適に伝達させることができるようになっている。また、固定部材２５は揉み玉２４よりも幅方向内側に突出しているため、使用者の首等を挟んでマッサージする際に、この固定部材２５が使用者とカバー部１３ｂを介して接触するため、ＰＴＣヒータ３０からの熱をより好適に伝達させることができるようになっている。また、アーム２２には電力供給線３５が固定されているため、マッサージ機構２０及びその施療子２１（アーム２２）をモータで動作させる際に、マッサージ機構２０及び施療子２１に電力供給線３５が絡まったり、電力供給線３５の屈曲や緊張状態となったりすることが抑えられている。このため、電力供給線３５の断線等の発生を低減させることが可能となっている。 As described above, since the heat can be transferred to the user's body with the heater unit 23 and the fixing member 25 as heat transfer means, there is a range in which heat is given to the user as compared with a conventional massage machine. The heat spreads from the PTC heater 30 as a heat source and can be suitably transmitted. Since the fixing member 25 protrudes inward in the width direction from the kneading balls 24, the fixing member 25 comes into contact with the user via the cover portion 13b when massaging the user's neck or the like. The heat from the PTC heater 30 can be more suitably transmitted. In addition, since the power supply line 35 is fixed to the arm 22, the power supply line 35 is connected to the massage mechanism 20 and the treatment element 21 when the massage mechanism 20 and the treatment element 21 (arm 22) are operated by a motor. It is possible to prevent the power supply line 35 from being tangled or from being bent or tensioned. For this reason, it is possible to reduce the occurrence of disconnection of the power supply line 35 and the like.
また、揉み玉２４が１つの弾性部材で構成されるため、従来のように揉み玉が分割タイプのものと比較して剛性及び耐久性を高めることができるようになっている。また、アーム２２に熱伝達手段としての第１及び第２ケース部材３１，３２が固定されているため、アーム２２と各ケース部材３１，３２との距離を小さくできるため、アーム２２動作に伴う各ケース部材３１，３２の振動の発生が抑えられている。これにより、各ケース部材３１，３２に収容されるＰＴＣヒータ３０の破損が抑えられている。 Further, since the kneading balls 24 are formed of a single elastic member, the kneading balls can be improved in rigidity and durability as compared with the conventional kneading balls. Further, since the first and second case members 31 and 32 as heat transfer means are fixed to the arm 22, the distance between the arm 22 and each case member 31 and 32 can be reduced. Generation of vibrations of the case members 31 and 32 is suppressed. Thereby, damage to the PTC heater 30 accommodated in each case member 31 and 32 is suppressed.
次に、本参考例の特徴的な作用効果を記載する。
（１）施療子２１は、マッサージ機構２０のアーム２２と接続されるとともにＰＴＣヒータ３０を収容して使用者にＰＴＣヒータ３０からの熱を伝達可能な第１及び第２ケース部材３１，３２と、使用者の身体を押圧する揉み玉２４とを備える。アーム２２と揉み玉２４との間にＰＴＣヒータ３０を収容した第１及び第２ケース部材３１，３２が設けられて構成される。つまり、従来のように揉み玉を分割して熱伝達手段を挟持する必要なく１部品で揉み玉２４を構成することができるため、熱伝達手段第２ケース部材３２にて使用者に熱を伝達させつつ揉み玉の剛性及び耐久性を向上させることが可能となる。また、揉み玉２４の部品点数を抑えることができ、製造時の組み立ての容易性を高くすることができる。
Next, characteristic actions and effects of this reference example will be described.
(1) The treatment element 21 is connected to the arm 22 of the massage mechanism 20 and accommodates the PTC heater 30 to transmit heat from the PTC heater 30 to the user. And kneading balls 24 that press the user's body. Between the arm 22 and the kneading balls 24, first and second case members 31 and 32 that accommodate the PTC heater 30 are provided. That is, the kneading balls 24 can be configured with one component without the need to divide the kneading balls and sandwich the heat transfer means as in the prior art, so that the heat transfer means second case member 32 transfers heat to the user. This makes it possible to improve the rigidity and durability of the kneading balls. Moreover, the number of parts of the kneading balls 24 can be suppressed, and the ease of assembly during production can be increased.
（２）ＰＴＣヒータ３０は、このＰＴＣヒータ３０に対して電力を供給可能な電力供給線３５が接続され、電力供給線３５は、アーム２２に固定される。ここで、施療子２１を構成するアーム２２はマッサージ機構２０とともに動作したり、揉み玉２４による身体への押圧動作に伴って動作したりする。この時、アーム２２に接続される熱伝達手段としての第１及び第２ケース部材３１，３２はアーム２２と略同様に移動するため、ＰＴＣヒータ３０への電力供給線３５をアーム２２に固定することで、電力供給線３５も一体で動作させることができ、電力供給線３５が屈曲したり緊張状態になったりすることが抑制される。このため、電力供給線３５の断線を低減させることができる。 (2) The PTC heater 30 is connected to a power supply line 35 that can supply power to the PTC heater 30, and the power supply line 35 is fixed to the arm 22. Here, the arm 22 which comprises the treatment element 21 operate | moves with the massage mechanism 20, or operate | moves with the press operation to the body by the kneading ball 24. FIG. At this time, since the first and second case members 31 and 32 as heat transfer means connected to the arm 22 move in substantially the same manner as the arm 22, the power supply line 35 to the PTC heater 30 is fixed to the arm 22. Thus, the power supply line 35 can also be operated integrally, and the power supply line 35 is prevented from being bent or in tension. For this reason, disconnection of the power supply line 35 can be reduced.
（３）熱伝達手段を構成する第１及び第２ケース部材３１，３２には、ＰＴＣヒータ３０が収容され、ＰＴＣヒータ３０は、熱伝達手段を構成する第１ケース部材３１に当接するように設けられる。このように第１ケース部材３１とＰＴＣヒータ３０とが当接する構成であるため、ＰＴＣヒータ３０からの熱を第１ケース部材３１側に確実に伝えることができ、第１ケース部材３１とＰＴＣヒータ３０とが当接しない構成と比較して伝熱の際のロスを抑えることができるため、低容量の熱源を使用することが可能となる。 (3) The PTC heater 30 is accommodated in the first and second case members 31 and 32 constituting the heat transfer means, and the PTC heater 30 is in contact with the first case member 31 constituting the heat transfer means. Provided. Since the first case member 31 and the PTC heater 30 are in contact with each other as described above, the heat from the PTC heater 30 can be reliably transmitted to the first case member 31 side, and the first case member 31 and the PTC heater can be transmitted. Since the loss during heat transfer can be suppressed as compared with a configuration in which the heat sink 30 does not contact, a low-capacity heat source can be used.
（４）施療子２１は、背もたれ部１３の幅方向に一対並設される。揉み玉２４は、背もたれ部の幅方向内側から第２ケース部材３２に対してねじ４６にて着脱自在な固定部材２５がその第２ケース部材３２に接続されて固定される。固定部材２５は、熱伝達手段としての第２ケース部材３２からの熱を使用者に伝達可能に構成される。このように、揉み玉２４を幅方向内側から第２ケース部材３２に対して着脱自在に接続する固定部材２５にて、第２ケース部材３２からの熱を使用者に対して伝達することで、使用者の身体のより広い範囲に熱を伝達することが可能となる。ここで、一対の揉み玉２４にて使用者の首等を挟むようにしてマッサージを行う場合には、揉み玉２４の幅方向内側の部位で挟むこととなる。このため、使用者の首のマッサージと同時に幅方向内側に設けられる固定部材２５にて、使用者の首に対しても熱を伝達させることができる。また、揉み玉よりも幅方向外側にＰＴＣヒータ３０を収容する第１及び第２ケース部材３１，３２を設けることで、使用者の首等の身体を揉み玉２４にて挟むようなマッサージを行う場合に、その固定部材２５と比較して大きな第１及び第２ケース部材３１，３２が使用者の身体にカバー部１３ｂを会して当接して揉み玉２４とは異なる感触（違和感）を与えるといったことが抑えられる。 (4) A pair of treatment elements 21 are arranged in parallel in the width direction of the backrest 13. The kneading balls 24 are fixed to the second case member 32 by a fixing member 25 that is detachably attached to the second case member 32 from the inner side in the width direction of the backrest portion. The fixing member 25 is configured to be able to transfer heat from the second case member 32 as heat transfer means to the user. In this way, by transmitting the heat from the second case member 32 to the user by the fixing member 25 that removably connects the kneading balls 24 from the inner side in the width direction to the second case member 32, It is possible to transfer heat to a wider area of the user's body. Here, when massage is performed with the pair of kneading balls 24 sandwiching the user's neck or the like, the massage is performed at the inner side of the kneading balls 24 in the width direction. For this reason, heat can be transmitted also to a user's neck with the fixing member 25 provided in the width direction inner side simultaneously with massage of a user's neck. In addition, by providing the first and second case members 31 and 32 that accommodate the PTC heater 30 on the outer side in the width direction than the kneading balls, a massage that sandwiches the body such as the user's neck with the kneading balls 24 is performed. In this case, the first and second case members 31 and 32 which are larger than the fixing member 25 meet the user's body with the cover portion 13b and come into contact therewith to give a feeling (uncomfortable feeling) different from that of the kneading balls 24. Can be suppressed.
（５）第１及び第２ケース部材３１，３２にて熱伝達手段が構成され、これら各ケース部材３１，３２にてＰＴＣヒータ３０が収容されるように構成される。このように、熱伝達手段を第１及び第２ケース部材３１，３２の複数の部材にて構成することで、熱伝達手段の内部にＰＴＣヒータ３０を容易に収容することが可能となる。 (5) The first and second case members 31 and 32 constitute a heat transfer means, and the case members 31 and 32 are configured to accommodate the PTC heater 30. In this way, by configuring the heat transfer means with a plurality of members of the first and second case members 31, 32, the PTC heater 30 can be easily accommodated in the heat transfer means.
（６）熱伝達手段としての第２ケース部材３２とＰＴＣヒータ３０との間には衝撃緩衝部材としてのゴムパッド４１が設けられるため、第１及び第２ケース部材３１，３２とＰＴＣヒータ３０との間に起こる負荷を抑え、ＰＴＣヒータ３０の破損等の発生を低減させることができる。 (6) Since a rubber pad 41 as an impact buffer member is provided between the second case member 32 as the heat transfer means and the PTC heater 30, the first and second case members 31, 32 and the PTC heater 30 The load that occurs in the meantime can be suppressed, and the occurrence of damage to the PTC heater 30 can be reduced.
（７）熱伝達手段としての第２ケース部材３２とＰＴＣヒータ３０との間には高熱伝導部材としてのゴムパッド４１が設けられるため、ＰＴＣヒータ３０と第２ケース部材３２との間のエアギャップをゴムパッド４１にて小さくでき、ＰＴＣヒータ３０から第２ケース部材３２への熱伝導性を高めることができる。このため、使用者に対して効率よくＰＴＣヒータ３０からの熱を伝達することが可能となる。 (7) Since the rubber pad 41 as the high heat conduction member is provided between the second case member 32 as the heat transfer means and the PTC heater 30, an air gap between the PTC heater 30 and the second case member 32 is provided. The size can be reduced by the rubber pad 41, and the thermal conductivity from the PTC heater 30 to the second case member 32 can be increased. For this reason, it becomes possible to transfer the heat from the PTC heater 30 to the user efficiently.
本発明を具体化した一実施形態について説明する。上記参考例では、ＰＴＣヒータ３０を収容する熱伝達手段としての第１ケース部材３１及び第２ケース部材３２を揉み玉２４の幅方向外側に配置している。この点について、本発明を具体化した一実施形態では、熱伝達手段としての第１ケース部材３１及び第２ケース部材３２を揉み玉２４の幅方向内側に配置する構成としている。この場合、固定部材２５は揉み玉２４よりも幅方向外側に配置することとなる。尚、その他の構成及び作用効果は、上記参考例と同様である。 An embodiment embodying the present invention will be described.
