  According to the above configuration, the treatment mechanism that can move in the vertical direction is built in the backrest, and the pair of left and right treatment arms in the treatment mechanism swings in the width, front, back, and up and down directions, and is provided at substantially the tip thereof. In the chair-type massage machine in which the treated treatment is performed on the back of the user such as a fir action or a tapping action, the treatment element that has been conventionally projected is retracted into the backrest in the present invention when not being treated, Further, the sheet body that covers the storage space formed for the treatment mechanism on the backrest is conventionally stretched on the surface of the backrest, and is stretched from the surface of the backrest. It forms with a heat generating body and it is made to heat | fever as needed.

  Therefore, even if the entire heating element generates heat, it is possible to perform the thermal stimulation locally only at the treatment site where the treatment element is applied, and not to apply the thermal stimulation only by retreating the treatment element. Thus, the thermal treatment can be quickly terminated while giving local thermal stimulation.

  In the chair type massage machine of the present invention, the sheet-like heating element is fixed with the upper end side serving as a fixed end and stretched by a tension spring with the lower end side serving as a free end.

  According to the above configuration, even when the user stands up, when the user stands on the backrest, the upper end side of the sheet-like heating element is fixed, so that the heating element is turned up, and the storage space Can be prevented from being fitted.

  As described above, the chair type massage machine of the present invention incorporates a treatment mechanism that can move in the vertical direction on the backrest, and the pair of left and right treatment arms in the treatment mechanism swings in the width, front and back, and vertical directions. In the chair type massage machine in which the treatment element provided at the substantially tip of the treatment performs treatment such as fir action and tapping action on the back of the user, conventionally, the treatment element that has been protruded, in the present invention, when not being treated The seat body that is retracted into the backrest and covers the storage space formed for the treatment mechanism in the backrest is conventionally stretched on the surface of the backrest. And is formed with a heating element, and generates heat as needed.

  Therefore, even if the entire heating element generates heat, it is possible to perform the thermal stimulation locally only at the treatment location where the treatment element is applied, and not to apply the thermal stimulation only by retreating the treatment element. Thus, the thermal treatment can be quickly terminated while giving local thermal stimulation.

  FIG. 1 is a perspective view of a chair type massage machine 21 according to an embodiment of the present invention, and FIG. 2 is a side view thereof. This massage machine 21 includes a seat portion 22 on which a user sits, a backrest portion 25 incorporating a treatment mechanism 24 including a treatment element 23 to be described later for performing upper body massage, an arm rest portion 26, and a lower leg portion And a leg holder 27 including an airbag for performing massage. There are some configurations such as an operation panel that are partially omitted.

  3 to 7 are diagrams for explaining the treatment mechanism 24 in detail, FIG. 3 is a perspective view of the treatment mechanism 24 as seen from the front side, and FIG. 4 is a perspective view of the treatment mechanism 24 as seen from the back side. 5 is a side view, FIG. 6 is a perspective view of the internal treatment element assembly 28 taken out, and FIG. 7 is a side view thereof. In addition, although the said treatment element 23 is comprised by left-right pair, in these figures, in order to make it easy to see, only the right treatment element is shown and the left treatment element comprised symmetrically is abbreviate | omitted.

  A pair of left and right drive shafts 32 and a guide shaft 33 protrude from the body frame 31 of the treatment mechanism 24, and slide in a guide groove (not shown) laid in the backrest portion 25. The treatment mechanism 24 can be moved up and down. Further, a gear 35 meshing with a rack rail (not shown) laid in the backrest portion 25 is attached to the drive shaft 32, and a motor (in the drawing, mounted on the right side portion of the main body frame 31). The worm and the gear housed in the gear box 39 are rotated and transmitted to the gear 35 through the drive shaft 32, and the treatment mechanism 24 is moved up and down in the backrest 25. It can be moved up and down in the direction to adjust the height and stretch the back.

  The treatment element assembly 28 is accommodated in the main body frame 31, and when the motor 36 provided on the side portion of the main body frame 31 rotates, the driving force is transmitted via a gear mechanism (not shown). Then, the treatment element assembly 28, which is transmitted to the gear 37 and supported by the main body frame 31 so as to be swingable around the shaft 38, swings. The treatment element 23 is pivotally supported at one end of a treatment arm 41 which is formed of a fir ball having an elastic surface and is formed in a substantially U shape in a side view. At the other end of the treatment arm 41, below the treatment element 23, a support member 42 made of resin or the like and capable of supporting the body of the user who has been undesirably fitted is attached. Then, as the treatment arm 41 swings about the shaft 38 in the substantially central portion, as shown in FIGS. 3A and 5A, the portion 41a on the treatment element 23 side of the treatment arm 41 is moved. From a non-treatment state substantially parallel to the backrest 25 to a slightly standing treatment state (weak) (not shown), as shown in FIGS. 3 (b) and 5 (b), a treatment state standing substantially vertically. It can be switched to (strong).

  On the other hand, the substantially U-shaped treatment arm 41 has a portion 41a on the treatment element 23 side and a portion 41b on the support member 42 side connected by a nodal point 41c so that the treatment arm 41 can be opened and closed freely. When the motor 44 mounted on the child assembly 28 is rotated, the eccentric shaft 40 having a phase difference of 180 ° on the left and right is rotated like a crankshaft via a gear (not shown) and the link 48 attached thereto is connected to the treatment 48. The part 41a of the arm 41 is swung on the side opposite to the treatment element 23, thereby performing a tatting operation. In addition, when the motor 34 mounted on the lower part of the main body frame 31 is rotated, the width of the pair of left and right treatment arms 41 is changed in synchronization with each other via a gear or a clutch mechanism (not shown). As a result, the treatment element 23 performs a fir operation on the user.

  In the massage machine 21 configured as described above, it should be noted that in the present embodiment, the treatment element 23 that has conventionally been projected is retracted into the backrest 25 during non-treatment as described above, Correspondingly, a sheet body 25b covering the storage space 25a formed for the treatment mechanism 24 on the backrest 25 is conventionally stretched on the surface of the backrest 25. As shown in FIG. 8, the backrest 25 is stretched from the surface of the backrest portion 25, and is formed of a heating element to generate heat as necessary.

  Specifically, a storage space 25a is formed in the backrest portion 25 so that the treatment mechanism 24 can be moved up and down, and the storage space 25a is covered with a sheet body 25b. In the present embodiment, as shown in FIG. 8, the sheet body 25b is fixed at positions P1 and P2 deeper from the surface 25f of the backrest 25 with the upper end side fixed as a fixed end and the lower end side set as a free end. It is stretched by a spring 45. Therefore, in the non-treatment state where the treatment element 23 is retracted as shown in FIGS. 3 (a) and 5 (a), the treatment element 23 and the sheet body 25b are as shown in FIG. 8 (a). It does not contact the user 46. On the other hand, in the treatment state in which the treatment element 23 protrudes as shown in FIGS. 3B and 5B, as shown in FIG. 8B, the treatment element 23 and the sheet body 25b. Contacts the user 46.

  Furthermore, by forming the sheet body 25b with a heating element and generating heat, in the treatment state, only the treatment location where the treatment element 23 is in contact can be locally stimulated (thermal treatment is performed). The temperature stimulation can be canceled when the state is switched to the non-treatment state. Thus, the thermal treatment can be quickly terminated while giving local thermal stimulation.

  Further, when fixing the sheet body 25b, the upper end side is fixed as a fixed end, and the lower end side is set as a free end and stretched by a tension spring 45, so that when the user 46 stands up, the hand rests on the backrest portion 25. Even if attached, it is possible to prevent the sheet body 25b from turning up and fitting into the storage space 25a.

  FIG. 10 is a block diagram showing an electrical configuration of the massage machine 21 configured as described above. When the main power switch 61 is turned on, power can be supplied from a commercial power source in the massage machine 1, and when the sub power switch 62 is turned on, power is supplied to the seat body 25b. The sheet body 25b generates heat.

It is supplied to the control circuit 65 and the like. As a result, an input operation from the input operation unit 66 of the operation device side control circuit 65 is accepted, and the main body side control circuit 64 determines the inclination angle of the massage mechanism 68 including the motors 34, 36, 44 and the backrest unit 25. The changing reclining mechanism 69 is driven to enable a massage operation. The massage mechanism 68 and the reclining mechanism 69 include a switch element that operates in response to a control signal from the main body side control circuit 64, and receives a voltage from the commercial power source or a voltage obtained by appropriately rectifying and stepping down the voltage. The switch element is ON / OFF controlled and applied to the motors 34, 36, 44, thereby performing the massage operation as described above.

  The operation state of each part during the massage is detected by various sensors 71 to 74, and the main body side control circuit 64 displays the progress state or abnormality of the massage on the display unit 67 via the operation unit side control circuit 65. To do. The sensor 71 detects the treatment element (fir ball) 23, that is, the vertical position of the treatment mechanism 24, the sensor 72 detects the width position of the treatment element 23, and the sensor 73 detects the protruding position of the treatment element 23 (see FIG. ), Whether it is the non-treatment position of FIG. 5 (a) and FIG. 8 (a), or is the treatment position of FIG. 3 (b), FIG. 5 (b) and FIG. 74 detects the rotational speed of the treatment element 23. The detection results of these sensors 71 to 74 are fed back to the control of the motors 34, 36, 44 and the like, and the massage operation as described above becomes possible according to a predetermined course menu or the like.

Even if not, the energization to the sheet body 25b is started, and the temperature rise is started as shown in FIG. 11B, and the treatment arm 41 is substantially vertical as shown in FIG. 11C. When the thermal treatment is started after being switched to the standing treatment state (ON), the temperature of the sheet body 25b is sufficiently increased, and the thermal stimulation can be started promptly (until the thermal stimulation is started). Time can be reduced).

  The sub power switch 62 prohibits the regular heat generation of the sheet body 25b in order to save power, and is constituted by a relay type switch. When the thermal treatment is selected, the main body side control It may be turned on by the circuit 64. Further, in a standby state, the sheet body 25b is driven with a low duty or a low current until the thermal treatment is selected, and is driven with a predetermined high duty or a large current when the thermal treatment is selected. Preheating may be performed.
