Description

  The present invention relates to a massage machine, and more particularly to a chair-type massage machine in which a treatment body is disposed on a backrest portion so as to be movable up and down.

  A general chair-type massage machine has a seat on which a user sits and a backrest at the back of the seat, and a massage mechanism with a treatment body is attached to the backrest so that it can be moved up and down. Has been.

  For example, in the conventional chair type massage machine 201 shown in FIG. 10, the massage mechanism 212 attached to the backrest part 205 is provided with a pair of kneading balls 214 and 214 as treatment bodies. In the state where it sits down (not shown), massage can be received by the operation of the kneading balls 214 and the lifting and lowering of the massage mechanism 212.

As the lifting mechanism of the massage mechanism 212, as shown in the drawing, a rack portion 211 and a concave rail portion 209 are formed on a pair of left and right vertical frames 210 and 210 constituting the outer edge of the backrest portion 205, respectively, while the massage mechanism 212 is formed. A pinion 216 and a guide roller 217 that mesh with the rack portion 211 are rotatably attached to the left and right ends of the rotation shaft 220 that are connected to the rotation shaft 220, and the pinion 216 is rotated by a motor (not shown) and the guide roller 217 is concave. The configuration of raising and lowering while abutting in the rail portion 209 has become standard (see Patent Document 1).
JP 2007-007208 A

  However, in the case of the above-described configuration, when the weight of the user is applied to the kneading balls 214 when massaging, the rotation shaft 220 connected to the massage mechanism 212 may be bent backward, and in that case, the rotation shaft 220 may be bent. There is a possibility that the positions of the pinion 216 and the guide roller 217 located on the outermost side will be shifted. As described above, when the massage mechanism 212 with the pinion 216 and the guide roller 217 being distorted moves up and down, there is a possibility that a loud operation sound is generated or the lifting operation is hindered.

  In addition, the vertical frame 210 constituting the outer edge of the backrest portion is not bent even if it receives a load in the front-rear direction due to the body weight of the user, and receives an unbalanced load via a massage mechanism. However, since it was necessary to form with the metal material which has sufficient rigidity so that it may not be distorted, the weight inevitably increased and the weight of the entire massage machine 201 was increased.

  The present invention has been made to solve the above-described problem, and an object of the present invention is to provide a massage machine capable of suppressing an operation sound when the massage mechanism is moved up and down while reducing the weight.

(1) In the present invention, an outer edge frame that forms an outer edge of the backrest portion, and a pair of left and right support frames that extend in the vertical direction at the center in the width direction of the outer edge frame, are provided between the support frames. In a massage machine that supports a massage mechanism that protrudes from a treatment body that comes into contact with a user so as to be able to move up and down, the support frame extends substantially linearly in the vertical direction and is movable in the front-rear direction. It was supposed to have flexibility.

  (2) In the above (1), the present invention includes a support mechanism that supports the massage mechanism so as to be movable up and down between the left and right support frames, and the support mechanism is in contact with a front side of the support frame. And a second rotating body that comes into contact with the rear side of the support frame, and the rotating mechanism allows the massaging mechanism to be raised and lowered with the support frame sandwiched from the front and rear. And

  (3) The present invention is the above (2), wherein the first rotating body is a pinion provided in the massage mechanism, and the pinion is formed in a protruding direction of the treatment body, and the support While engaging with the rack attached to the frame, the second rotating body is a guide roller connected to the pinion via a connecting member, and the support frame is sandwiched from the front and rear by the guide roller and the pinion. The massage mechanism can be moved up and down in a state.

  According to the present invention, a pair of left and right support frames extending in the vertical direction is provided at the center in the width direction of the outer frame that forms the outer edge of the backrest, and the user is in contact with the support frame between the support frames. Since the massage mechanism with a treatable treatment body protruding is supported so that it can be raised and lowered, when the weight of the user is applied to the massage mechanism, there is no lifting mechanism on the outer edge frame, and the weight is not There is no need to increase the rigidity and design accuracy of the outer edge frame because it is not directly received, and for example, lightweight materials are used as the material for both frames by designing the outer frame and the support frame with appropriate strength. This makes it possible to reduce the weight of the massage machine.

  The massage machine according to the present embodiment includes an outer edge frame that forms an outer edge of a backrest portion, and a pair of left and right support frames that extend in the vertical direction at the center in the width direction of the outer edge frame, and the support frame In between, the massage mechanism in which the treatment body which can be treated in contact with the user is protruded is supported to be movable up and down. That is, a pair of narrow left and right support frames are separately provided for the outer edge frame having a wide left and right width, and a massage machine is attached to the frame so as to be movable up and down. In addition, as a treatment body, a pair of left and right fir balls can be suitably used.

  The massaging mechanism includes a support mechanism that supports the massage mechanism so as to be movable up and down between the left and right support frames. The support mechanism includes a first rotating body that contacts the front side of the support frame, and the support A second rotating body abutting on the rear side of the frame, and the massaging mechanism can be moved up and down with these rotating bodies sandwiching the support frame from the front and rear. Therefore, the outer frame that does not support the massage mechanism does not require much rigidity and accuracy, and the support frame that receives the weight of the user via the treatment body is sandwiched from the front and rear of the frame. Since the support mechanism is provided with the first and second rotating bodies that can move the massage mechanism up and down, even if the support frame is slightly bent in the direction in which the load is applied, there is no problem in raising and lowering the massage mechanism. Therefore, a smooth raising / lowering operation can be realized. That is, the support frame is not required to have rigidity that is not allowed to bend, so that the weight of the entire frame can be reduced, and the weight of the entire massage machine can be reduced.

  As described above, the characteristic configuration of the massage machine according to the present embodiment is that, apart from the outer edge frame that forms the backrest part, a support frame that supports the massage mechanism is provided at the center in the width direction of the outer edge frame. In particular, it has become possible to reduce the weight of the outer edge frame, which has conventionally required sufficient rigidity, and the left and right support frames disposed narrower than the width between the left and right outer edge frames include: Since the load applied by the user is applied without being biased, it is not necessary to consider much twisting, etc., and the degree of bending back and forth does not hinder the lifting and lowering of the massage mechanism, so it is also possible to use lightweight materials for the support frame It is possible. Therefore, the weight reduction of the whole massage machine can be achieved.

  In the above configuration, the first rotating body is a pinion provided in the massaging mechanism, and the pinion is meshed with a rack in which teeth are formed in the protruding direction of the treatment body and attached to the support frame. On the other hand, the second rotating body is a guide roller connected to the pinion via a connecting member, and the massage mechanism can be moved up and down with the guide roller and the pinion sandwiching the support frame from the front and rear. can do.

  In other words, the weight of the user is applied to the support frame in the front-rear direction, but the support roller is sandwiched from the front and rear by the guide roller and the pinion, so that the guide roller always applies a pressing force in the direction in contact with the pinion. While rotating, the massage mechanism can be moved up and down smoothly. Moreover, the space between the left and right support frames is much narrower than that between the left and right outer edge frames, and the load applied to the support frame from the user via the massage mechanism is less likely to be biased. There is no slippage or stagnation.

  Further, it is preferable that at least the rack and the pinion are formed of a synthetic resin, which can be much lighter than that made of metal, and is due to the engagement of the rack and the pinion that occurs when the massage mechanism moves up and down. The noise can be reduced by suppressing the sound.

  In the configuration described above, the outer edge frame and the support frame may be specifically formed of a material that is lighter than the frame of a conventional chair type massage machine. By setting it as this structure, the weight reduction of a massage machine can be achieved reliably. The material is not particularly limited as a lightweight material, but it is not limited to a metal material, particularly a support frame, and a flexible material can be advantageously applied. For example, a carbon material, a synthetic resin material, a foam material, etc. Conceivable. If the support frame has sufficient strength to support the human body, the outer edge of the support frame may be a frame made of, for example, a synthetic resin plate having a predetermined width. Included in the frame concept.

  Further, the support frame can be formed of a material that extends substantially linearly in the vertical direction and has flexibility in the front-rear direction. By adopting such a configuration, while using the massage machine from the beginning, the support frame bends back and forth appropriately according to the body shape and weight of the user, and becomes a shape that fits the user Therefore, the usability as a massage machine is remarkably improved, and the treatment effect can be improved.

  In addition, the said support frame specifically applies the circular pipe shape shown in FIGS. 1-8, or the press goods as shown in FIG.

  By making it a circular pipe shape, it is possible to maintain strength while reducing weight, and if the circumferential curved surface of the circular pipe is sandwiched between the front and rear by a pinion and a guide roller, the massage mechanism is a pinion The guide roller moves up and down while holding the circular pipe, and can smoothly move up and down without rattling.

  In addition, when using press products, the manufacturing cost can be further reduced. Especially when mounting a resin rack, mounting holes are opened in the support frame, but the positional accuracy in that case is better than that of a circular pipe. This is also advantageous.

  In the case of the embodiment shown in FIG. 9, which is considered particularly desirable, the mounting side of the rack is flat as a cross-sectional hat shape, and the shape of the side received by the guide roller is circular as in the case of the circular pipe.

  With such a configuration, the mounting property of the rack is further improved, while the direct pressing force of the human body can be favorably received by the contact with the guide roller having a concave section.

  Note that it is not always necessary to use a pinion and a rack as the lifting mechanism of the massage mechanism. For example, a pair of front and rear guide rollers that sandwich the support frame from the front-rear direction may be provided in the massage mechanism, and the massage mechanism may be hung up and down by, for example, a wire.

  Even with such a configuration, it is possible to suppress the operation sound during the lifting and lowering operation of the massage mechanism, thereby reducing the noise and reducing the weight of the massage machine.

  You may comprise so that a support frame may be supported by the said outer edge frame via an elastic body.

  According to such a configuration, the elastic body expands and contracts according to the load due to the weight of the user, so that the support frame sinks back and forth from the outer frame, and the massage mechanism performs the massage while wrapping the body shape of the user Can do. The massage mechanism is moved up and down by a rack and pinion, and the support frame is sandwiched from the front and rear by a pinion and a guide roller disposed on the back thereof, or a pair of front and rear guides that clamp the support frame from the front and rear. If it is the structure etc. which are supported by the roller, there will be no trouble even when the massage mechanism moves up and down the support frame.

  Further, in this case, the outer edge frame may be formed of a material having a higher strength than the support frame, and even if the weight of the massage mechanism itself or the weight of the user is applied to the support frame, the support frame Is firmly supported by an outer frame made of a high-strength material via an elastic body, so there is no possibility that the backrest portion will be deformed.

A backrest portion 5 connected so as to be able to recline freely, and a leg rest portion 7 connected to be swingable in the vertical direction around a pivotal support portion 6 provided in the vicinity of the upper front side of the seat portion 2. Each part except the base part 3 is covered directly or via a cushion member with a cover made of synthetic leather or the like as necessary.

  As shown in the figure, the massaging machine 1 according to the present embodiment has a vertical configuration in the center in the width direction of the outer edge frame 10 formed in a substantially rectangular cross-sectional view channel shape forming the outer edge of the backrest portion 5. A pair of left and right fir balls 14a as a treatment body which is provided with a support frame 11 composed of a pair of left and right circular pipes extending in the direction and which can be treated by pressing against the user between the support frames 11; This is because a massage mechanism 12 to be described later on which 14b protrudes is supported to be movable up and down.

  The massage machine 1 also includes a support mechanism that supports the massage mechanism 12 so that it can be moved up and down between the left and right support frames 11, 11. The support mechanism is in contact with the front side of the support frames 11, 11. And a second rotating body that abuts on the rear side of the support frames 11 and 11, and the massage mechanism in a state where the support frames 11 and 11 are sandwiched from the front and rear by the two rotating bodies. 12 can be moved up and down. Specifically, as shown in FIGS. 3 and 4, a rack 13 having a large number of tooth rows is attached to the front side of each support frame 11, and a pinion 17 meshing with the rack 13 is connected to the first rotating body. In addition, the frame support portion 15 is connected to the pinion 17 via a U-shaped connecting member 16 and a guide roller 18 disposed so as to contact the rear side of each support frame 11 as a second rotating body. Are provided at two locations on each support frame 11.

  As shown in FIG. 3, the pinions 17 of the left and right frame support portions 15 positioned below are respectively connected to an elevating rotary shaft 20, and the elevating rotary shaft 20 is interlocked with the elevating motor m <b> 1. It is connected.

  On the other hand, as shown in FIGS. 3 and 4, the pinions 17 of the frame support portion 15 positioned above are connected to each other via an advancing / retracting shaft 21 that moves the massage mechanism 12 back and forth. It meshes with a rack 13 disposed on the support frame 11.

  As shown in FIG. 4B, the peripheral surface 22 of each guide roller 18 is a concave curved surface corresponding to the peripheral curved surface 23 of the support frame 11 made of a circular pipe, and each guide roller 18 is connected to the pinion 17. In cooperation with each other, the support frame 11 is rotated up and down while being held from the rear side.

  The pinion 17, the rack 13, and the guide roller 18 in the present embodiment are all formed of synthetic resin, so that the weight of the support mechanism is reduced.

  In addition, the pinion 17 and the guide roller 18 are pivotally supported by the connecting member 16 and move up and down in a state where the support frame 11 is sandwiched from the front and rear by the pinion 17 and the guide roller 18, so that a stable lifting operation is possible. In addition, unlike the case where the metals are in contact with each other, the noise is very high when moving up and down.

  As shown in FIGS. 1 and 2, the outer edge frame 10 is arranged so that left and right vertical frames 25 having a U-shaped cross section face each other, and a horizontal frame 26 is connected to the upper and lower ends of both vertical frames 25. To form a substantially rectangular frame. The support frame 11 is connected and fixed between the upper and lower horizontal frames 26 and 26 via an attachment member 27. The attachment member 27 is substantially U-shaped in sectional view so as to engage with the horizontal frame 26, and both end portions of the support frame 11 are fixed.

  The outer edge frame 10 is pivotally supported by a base frame 30 that constitutes the base portion 3. That is, as shown in FIG. 1 and FIG. 2, the base frame 30 is configured by connecting a plurality of frames, and left and right corner frames 31, 31 constituting the bottom of the base frame 30, The connecting frames 32 and 32 for connecting the front and middle portions of the corner frames 31 and 31 respectively, the pivot frame 33 standing from the middle portions of the left and right corner frames 31, and the left and right corner frames 31 The front frame 34 is erected from the front portion, and the pivot support portion 9 is provided at the rear end position of the upper end of the pivot support frame 33, and the bracket 36 provided in the middle of the outer frame 10 through the pivot support portion 9. Are connected.

  Then, by connecting an actuator (not shown) to the bracket 36, the outer edge frame 10 can be rotated around the pivotal support portion 9, and the backrest portion 5 can be reclined.

  In the figure, reference numerals 35 and 35 denote plate plates spanned between the front frame 34 and the upper front side of the pivotal support frame 33, and a seat plate cushion (see FIG. (Not shown) can be placed.

  By the way, in this embodiment, although both the outer edge frame 10 and the support frame 11 are made of metal, for example, the massage mechanism 12 or the like is not supported, and the weight of the user is directly received. The outer edge frame 10 is made of a lightweight synthetic resin material, carbon fiber, or the like, and is much lighter than the support frame 11. The weight of the entire machine 1 can be further reduced.

  Next, the massage mechanism 12 attached to the support frames 11, 11 will be described. As shown in FIG. 4 (b), the massage mechanism 12 includes a connecting member 16 that connects the pinion 17 and the guide roller 18 of the frame support portion 15 provided on the left, right, and upper sides via a connecting member 19 between the upper and lower sides. Connected to form a frame structure, and necessary members are appropriately connected to the rotating shaft 20 and the advancing / retracting shaft 21 for connecting the pinions 17 between the frames, and a pair of left and right fir balls 14a, which are treatment bodies, The kneading ball drive unit 40 which drives 14b is provided.

  The kneading ball drive unit 40 has a striking mechanism that performs a striking operation by swinging the kneading balls 14a and 14b in the up-and-down striking direction, and a kneading mechanism that performs a fouling operation by eccentrically rotating the fir balls 14a and 14b. And an advance / retreat mechanism for moving the massage mechanism 12 forward and backward toward the front side of the backrest 5, that is, toward the user. And depending on the advancing / retreating position, the pressure applied to the user by the kneading balls 14a, 14b can be changed to change the massage strength.

  The hitting mechanism includes a hitting motor m4 as a main component, and is linked to the hitting balls 14a and 14b via a hitting rotation shaft (not shown) to cause the hitting balls 14a and 14b to hit.

  Further, the kneading mechanism includes a kneading motor m3 as a main component, and is linked to the kneading balls 14a and 14b via a kneading rotation shaft (not shown) so that the kneading balls 14a and 14b perform a kneading operation. .

  The advancing / retreating mechanism includes an advancing / retreating motor m2 as main components, an advancing / retracting shaft 21 rotated by the advancing / retreating motor m2, a pinion 44 provided on the advancing / retreating shaft 21, and an arcuate rack 46 with which the pinion 44 meshes. And the entire kneading ball drive unit 40 can be moved forward and backward. That is, when the advancing / retracting motor m2 is driven, the advancing / retracting shaft 21 rotates, and the pinion 44 attached to the advancing / retracting shaft 21 moves in the front-rear direction on the arc-shaped rack 46, so that the fir tree drive unit 40 draws an arc. Move forward and backward.

  In the present embodiment, since a predetermined gap is formed between the vertical frame 25 of the outer edge frame 10 and the support frame 11, by arranging an elevating motor m1, an advancing / retreating motor m2, etc. in the gap, The massage mechanism 12 can be efficiently arranged in the backrest part 5 and the weight balance between the left and right is improved.

  Hereinafter, the other structure with which this massage machine 1 is provided is demonstrated easily. In FIGS. 1 and 2, reference numeral 4 denotes a side wall portion functioning as a body side treatment portion attached to the vertical frame 25 of the outer edge frame 10, and 8 denotes an armrest portion provided on the left and right sides of the seat portion 2. Reference numeral 52 denotes a leg rest main body part in which semi-cylindrical left and right leg rests are arranged side by side, and 53 denotes a sole rest part.

  Although not shown, a heel lower part airbag is attached to the rear side of the seat part 2, a thigh airbag is attached to the front part, and a heel side airbag is attached to the left and right sides, respectively. The leg upper airbag and the leg lower airbag are also attached. Further, a back airbag is disposed at the upper left and right sides of the backrest 5 and a lower airbag is disposed at the lower left and right sides. Each air bag is inflated and contracted by air supplied from an air pump (not shown) disposed in the base 3 and can perform air massage.

  As described above, the massage machine 1 according to the present embodiment has a configuration in which the massage mechanism 12 is disposed so as to be movable up and down on the left and right support frames 11 and 11 extended vertically to the center position of the outer edge frame 10. In order for the user to receive massage, when sitting on the seat 2 and leaning on the backrest 5, the weight is applied to the rear. At this time, a backward load is applied to the massage mechanism 12, and the load is transmitted to the support frame 11 that supports the massage mechanism 12, and the support frame 11 is bent slightly backward. It is possible to become.

  In this state, when the massage mechanism 12 is moved up and down, the power from the lifting motor m1 is transmitted to the pinion 17 via the rotating shaft 20, and the massage mechanism 12 is driven up and down as the pinion 17 rotates. Since the guide roller 18 and the pinion 17 rotate in a state where the left and right support frames 11 are sandwiched from the front and rear directions by the frame support portion 15, regardless of the load applied to the support frame 11 and the slight deflection in the front and rear directions therefor, The massage mechanism 12 moves up and down smoothly, and the rack 13, the guide roller 18 and the pinion 17 are made of synthetic resin, so that operation noise generated during operation is remarkably suppressed.

  Moreover, in the massage machine 1 of this embodiment, since the support frame 11 which supports the massage mechanism 12 in the width direction center part of this outer edge frame 10 was provided separately from the outer edge frame 10 which forms the backrest part 5, conventionally, It is possible to reduce the weight of the outer edge frame 10 that requires sufficient rigidity.

  Furthermore, the left and right support frames 11 and 11 disposed narrower than the left and right vertical frames 25 and 25 of the outer edge frame 10 are subjected to twisting and the like because the load applied by the user is applied without being biased. There is no need to consider so much, and the degree of bending back and forth has no hindrance to raising and lowering the massage mechanism 12 due to the configuration of the support mechanism (frame support portion 15) described above. Therefore, it is also possible to use a light material for the support frame 11, and a greater weight reduction can be expected.

  Further, the support frame 11 according to the present embodiment is formed of a metal circular pipe, and is extended and arranged substantially linearly in the vertical direction. As a modification thereof, the support frame having flexibility in the front-rear direction is provided. 62.

  Hereinafter, Modification 1 of the first embodiment will be described. FIG. 5 is an explanatory diagram in a cross-sectional view illustrating a first modification of the first embodiment. In FIG. 5, the degree of bending of the support frame is exaggerated for easy understanding. The difference between the first embodiment and the first modification is that the support frame has flexibility in the front-rear direction and plastically deforms over time.

  As shown in FIG. 5, the flexible support frame 62 according to the first modified example has a rearward direction as shown by a one-dot chain line, for example, when a load is repeatedly applied by the user to perform massage. Deforms into a bowed state.

  However, as described above, the massage mechanism 12 is supported by the frame support portion 15 at four locations on the upper, lower, left, and right sides of the support frame 62, and the support frame 62 is moved back and forth by the pinion 17 and the guide roller 18 of the frame support portion 15. It is clamped from the direction. Therefore, even when the support frame 62 is curved, the lifting and lowering operation of the massage mechanism 12 is not hindered, and it is possible to maintain the silence without generating an operation sound due to the engagement between the pinion 17 and the rack 13. In addition, since the degree of bending of the support frame 62 in the front-rear direction is in accordance with the body shape of the user, the backrest part 5 fits the user, and a comfortable massage for the user is realized. Thus, according to the first modification, while the user uses the massage machine 1, the support frame 62 bends in the front-rear direction according to the weight and body shape of the user, It transforms into a shape that fits the body shape. Therefore, the usability as the massage machine 1 is improved and the treatment effect is also improved.

  According to the first modification, the support frame 62 extends substantially linearly in the vertical direction and has flexibility in the front-rear direction. However, the outer edge frame 10 in this case is preferably higher than the support frame 62. It is good to form with a strength material. Alternatively, even if the strength is not particularly higher than that of the support frame 62, it is necessary to have a strength that does not cause deformation when a load is applied through the support frame 62.

  Next, Modification 2 of the first embodiment will be described. FIG. 6 is a front view showing a second modification of the first embodiment. In the second modification, the outer edge frame is formed in a plate shape.

  As shown in FIG. 6, the outer edge frame 70 of the backrest 71 according to the modified example 2 is formed in a rectangular frame shape with a long plate-like plate body having a predetermined width, using a foam material or a synthetic resin material. This is the skeleton of the backrest 71. A support frame 11 that supports the massaging mechanism 12 so as to be movable up and down is disposed in a space surrounded by the outer edge frame 70.

  According to the second modification, the backrest 71 can be significantly reduced in weight. The foam material of the outer frame 70 can be directly covered with a cover made of synthetic leather or the like, and the backrest 71 can be reduced in weight. In addition, as in this example, the outer edge frame 70 may be formed of a single material, or may be formed by overlapping a foam material and a synthetic resin material, for example.

  Further, the flexible support frame 62 in the first modification may be applied to the backrest 71 of the second modification.

  A second embodiment of the massage machine according to the present invention will be described with reference to FIG. FIG. 7A is an explanatory diagram showing the support mechanism of the massage mechanism in a side view, and FIG. 7B is an explanatory diagram in a plan view of the frame support portion.

  In this embodiment, the massage mechanism 12 is moved up and down without using the pinion 17 of the frame support portion 15 of the massage mechanism 12 according to the first embodiment and the rack 13 attached to the support frame 11. There is a feature in that. That is, in this embodiment, the frame support portion 15 includes a front guide roller 83 and a rear guide roller 89 that sandwich the support frame 11 in the front-rear direction, and the frame support portion 80 is suspended by the wire 82. The massage mechanism 12 is moved up and down along the support frame 11 via the wire 82.

  As shown in FIG. 7A, an upper bracket 85 and a lower bracket 86 are connected to a connecting member 16 that connects a front guide roller 83 as a first rotating body and a rear guide roller 89 as a second rotating body. Are connected to each other, and end portions of the wires 82 are connected to the upper bracket 85 and the lower bracket 86, respectively. The wire 82 is wound around pulleys 88, 88 respectively disposed above and below in the backrest 5, and the lower pulley 88 is linked to a winding motor 87.

  The front and rear guide rollers 83 and 89 are each made of synthetic resin, and the front guide roller 83 has a larger diameter than the rear guide roller 89, and both guide rollers 83 and 89 are as shown in FIG. In addition, the peripheral surfaces 84 and 22 are formed in a concave curved surface corresponding to the peripheral curved surface 23 of the circular pipe of the support frame 11, abutting from the front and rear sides of the support frame 11, and holding the support frame 11. Rotates up and down.

  With this configuration, if the winding motor 87 is rotated forward and backward to move the wire 82 up and down, the massage mechanism 12 can be moved up and down along the support frame 11 in a stable state. In addition, since it is lifted and lowered through the wire 82 and the front guide roller 83 and the rear guide roller 89 are made of synthetic resin, the sound generated by the lifting operation is suppressed and extremely quiet.

  Finally, a third embodiment of the massage machine according to the present invention will be described with reference to FIG. In the present embodiment, the outer edge frame is made of a material stronger than the support frame, and the support frame is suspended from the outer edge frame via an elastic body.

  As shown in the drawing, an outer edge frame 90 that forms the outer edge of the backrest 5 is formed in a substantially rectangular frame shape, and is supported on horizontal frames 92 and 92 arranged vertically via a coil spring 102 as an elastic body. The frame 103 is suspended. The support frame 103 according to the present embodiment has a substantially rectangular frame like the outer edge frame 90 by connecting the upper ends and lower ends of the left and right vertical pipes 104, 104 provided with the rack 13 on the front surface with the horizontal pipes 105, 105. The coil spring 102 is connected to the four corners of the support frame 103.

  Also in this embodiment, the massage mechanism 12 is attached to the support frame 103 by the frame support portions 15 provided at four places so as to be movable up and down, as in the previous embodiments. And a guide roller 18 that contacts the rear side of the support frame 103 (see FIG. 4).

  As described above, when the support frame 103 is supported on the outer edge frame 10 via the elastic body, when the massage mechanism 12 moves up and down between the support frames 103, the elastic body is used according to the weight of the user. A certain coil spring 102 extends, and the support frame 103 sinks behind the outer edge frame 90. That is, since a bending moment or the like due to a load is not applied to the support frame 103, the strength of the support frame 103 is not necessary so much as long as the massage mechanism 12 can be supported. Therefore, in this embodiment, the outer edge frame 90 is formed of a high-strength material rather than the support frame 103.

  Further, when the outer edge frame 90 is formed of a high-strength material in this way, for example, even if some large external force is applied to the backrest portion 5, the outer-edge frame 90 is formed of a high-strength material. Will not be deformed.

  Even if the support frame 103 sinks below the outer edge frame 90, the massaging mechanism 12 is firmly supported by the support frame 103 via the frame support portion 15, so that there is no hindrance to the lifting operation. In addition, when the support frame 103 sinks, the body of the user is also sinked into the outer frame 90, so that the user is wrapped in the backrest 5 and a comfortable massage can be realized. .

  In addition, also in the structure of the backrest part 5 which concerns on this embodiment, the massage mechanism 12 can be raised / lowered by methods other than a rack and pinion system like the wire drive shown in FIG. Of course, in that case, the frame support portion 15 may be provided with front and rear guide rollers.

  In the example described above, the support frame has been described as a circular pipe. However, as shown in FIG. 9, a press product having a cross-sectional hat shape may be employed.

  As shown in the drawing, the support frame 110 has a groove portion 112 having a substantially U-shaped cross section in a circular arc shape on the side receiving the guide roller 18 and the rear guide roller 89 as in the case of a circular pipe, and the groove portion 112. These are bent outwardly from the left and right sides, and are integrally press-molded from the flanges 111 and 111 which are the mounting surfaces of the rack 13, and are formed into a cross-sectional hat shape. A rack 130 integrally formed of resin is attached on the flanges 111 and 111 through an attachment hole (not shown).

  As described above, the support frame 110 is press-molded to further reduce the manufacturing cost. In particular, since the mounting hole has a better positional accuracy than the circular pipe, the mounting property of the rack 130 is improved. In addition, it is advantageous in terms of cost. Moreover, even in this case, the direct pressing force of the user can be received well by contact with the guide roller 18 (89) having a concave cross section as described above.
