Since the upper and lower portions of the ball screw 53 are threaded in opposite directions to form a right screw 53a and a left screw 53b, the ball nuts 55 and 56 screwed together are both bearings 54 (or It approaches or separates from the gear 57). In the present embodiment, when the motor 59 rotates in one direction, the ball nuts 55 and 56 both operate so as to be close to the bearing 54, and when the motor 59 rotates in the other direction, the ball nut 55 and 56 move toward the other. Operate to separate.

  When the ball nuts 55 and 56 move so as to be close to the bearing 54, the ball nut 55 itself is fixed to the lateral frame 17c, so that the lower leg support portion 10a to which the motor 59 is attached together with the ball screw 53 and the motor 59 is provided. Move up. In addition, since the other ball nut 56 that moves closer to the bearing 54 is fixed to the foot support portion 11 a, the foot support portion 11 a also moves upward along with the ball nut 56 toward the bearing 54. As a result, when the motor 59 rotates in one direction, the crus support part 10a and the foot support part 11a move up, and the right footrest 4a moves out. In addition, by the structure of the expansion-contraction mechanism 50 mentioned above, the leg support part 11a will rise at a speed twice as high as the raising speed of the crus support part 10a.

  On the other hand, when the motor 59 rotates to the other side and the ball nuts 55 and 56 move away from the bearing 54, the lower leg support portion 10a moves down together with the ball screw 53 and the motor 59. Further, the foot support portion 11a also moves down together with the other ball nut 56. As a result, when the motor 59 rotates to the other side, the lower leg support portion 10a and the foot support portion 11a perform the lowering operation, and the right footrest 4a performs the distraction operation. As in the case of ascending, the foot support part 11a descends at a speed twice as fast as the descending speed of the crus support part 10a.

  In the telescopic mechanism 50 of the chair type massage machine 1 according to the present embodiment, the ball screw 53, the bearing 54, the ball nuts 55 and 56, the motor 59 and the like as described above are compatible not only with the right footrest 4a but also with the left footrest 4b. It is provided as. Therefore, the right footrest 4a and the left footrest 4b can be expanded and contracted independently of each other. For example, FIG. 6 used in the above description shows a state in which both the right footrest 4a and the left footrest 4b are retracted, FIG. 7A shows a state in which only the left footrest 4b is extended, and FIG. Is a state in which only the right footrest 4a is extended, and FIG. 7C shows a state in which both the right footrest 4a and the left footrest 4b are extended.

Accordingly, when the drive unit 95 is driven and the motor 59 is rotated to one side, one or both of the right footrest 4a and the left footrest 4b are retracted, and when the motor 59 is rotated to the other, the extension operation is performed.

  The operation of each unit performed by driving the driving units 92 to 95 is controlled by a signal from the control unit 90. The user operates the operation device 91 to determine what operation is to be performed. Can be determined by The operation device 91 includes an input unit (not shown) that can select, for example, a neck stretch, an arm stretch, a spine stretch, and a leg stretch as various stretches. . The user can cause the chair type massage machine 1 to execute a desired stretching operation by operating the input unit.

  The control unit 90 is connected to a switch 81 (see FIG. 1) provided near the grip 80 of the gripping unit 63. When the user operates the switch 81, a corresponding instruction signal is output to the control unit 90, and the control unit 90 inflates and inflates the air bags 71 to 74 included in the seat surface operation unit 60 based on the input signal. The height of the seating surface 2b is adjusted by contraction.

  According to the chair type massage machine 1 as described above, effective stretching can be performed on various parts of the body of the user. FIG.11 and FIG.12 has illustrated typically the attitude | position change of the to-be-treated person during the stretch regarding the stretch with respect to the user realizable by the chair type massage machine 1, and the chair type massage machine 1 at the time of each stretch. It is drawing for demonstrating operation | movement.

  FIGS. 11A and 11B show changes in the posture of the user when the neck of the user is stretched. When performing such neck stretch, the backrest 3 of the chair-type massage machine 1 is in an upright state, and the user is in a sitting position as shown in FIG. Yes. Next, when the operation device 91 (see FIG. 10) is operated by the user and an instruction to perform neck stretching is input, an instruction from the control unit 90 is provided on the backrest 3. The neck support portion 61 (see FIG. 1) thus operated operates, and the air bags 75 and 76 are simultaneously inflated to support the neck portion of the user from the left and right. Subsequently, according to an instruction from the control unit 90, the backrest 3 tilts backward while the neck is supported.

  By doing so, the upper body of the user tends to shift toward the seat portion 2 due to the tilt of the backrest portion 3, but this positional shift is suppressed by supporting the neck portion with the neck support portion 61. . As a result, the neck is pulled upward, and the neck can be stretched.

  In addition, if it replaces with the support of the neck part by the neck support part 61 and the treatment element 101 which the mechanical massage mechanism 100 (refer FIG. 1) contact | abuts to a neck part, it is possible to give a massage to the neck part. . That is, the treatment element 101 is raised and positioned at the back of the neck, and further protrudes forward. If it does in this way, since the treatment element 101 will contact | abut to a patient's neck part (actually contact | abuts via the cover which wraps the backrest part 3), the backrest part 3 inclines back in this state As a result, the neck portion of the treatment element 101 tends to fall along the backrest portion 3. Accordingly, at this time, the neck can be massaged with the treatment element 101. When performing such a massage, in addition to the aspect of the treatment element 101, a roller (not shown) dedicated to the neck is provided on the backrest 3, and the back is in a state where the roller is in contact with the neck. It can also be performed by tilting the drooping portion 3.

  11 (c) and 11 (d) show the posture change of the user when the arm part of the user is stretched. When stretching such an arm part, the backrest part 3 of the chair type massage machine 1 is in an upright state, and the user places the forearm on the armrest 5 (see FIG. 1). Then, it is in a sitting posture as shown in FIG. Next, when the operating device 91 (see FIG. 10) is operated by the user and an instruction to execute arm stretching is input, the arm 90 is provided above the armrest 5 according to the instruction from the control unit 90. Further, the forearm support portion 64 (see FIG. 9) operates, and all of the air bags 86 to 88 are inflated to support the user's forearm from above and below. Subsequently, in response to an instruction from the control unit 90, the backrest unit 3 tilts backward while the forearm is supported.

  By doing so, the arm part tends to shift backward as the upper body of the user tilts backward due to the tilt of the backrest part 3, but the forearm support part 64 supports the forearm. This positional shift is suppressed. As a result, the arm part is pulled backward, and the arm part can be stretched. In supporting the forearm, it is not necessary to inflate all of the air bags 86 to 88 included in the forearm support portion 64, and only one or two of these may be inflated.

  12A and 12B show changes in the posture of the user when the user's back muscles are stretched. When performing such back muscle stretching, the backrest 3 of the chair-type massage machine 1 is in an upright state, and the user is seated on the seat 2. Next, when the operation device 91 (see FIG. 10) is operated by the user and an instruction to execute the stretching of the back muscles is input, the seat surface operation unit 60 is driven by the instruction from the control unit 90. The air bags 71 to 74 are inflated and the seat surface 2b is raised. Then, the user grips the grip 80 of the grip portion 63 by extending the arm portion above the head.

  Here, as already described, the height of the grip 80 can be arbitrarily set by adjusting the adjuster. When the back muscles are stretched, the height that the user seated on the seating surface 2b extends with the arm portion above the head while the seating surface 2b is positioned upward by the operation of the seating surface operating unit 60. It is preferable that the position of the grip 80 is set.

  Next, when the user operates the switch 81 provided in the vicinity of the grip 80 while holding the grip 80, the seat surface operation unit 60 is driven by the instruction from the control unit 90, and the inflated air The bags 71 to 74 are evacuated and contracted to lower the seat surface 2b. At the same time, the backrest 3 tilts backward. During this time, the user keeps the grip 80 held.

  In this way, after the user operates the switch 81, the seat surface 2b is lowered, so that the user who is gripping the grip 80 is in a state where the butt portion is lifted and the back muscles can be stretched. . Further, since the backrest 3 tilts backward simultaneously with the lowering of the seating surface 2b, the upper body of the user is warped, so that the back muscles can be stretched further. In addition, although the case where the whole seat surface 2b was moved up and down at the time of stretching the back muscles was described, only the air bags 73 and 74 may be expanded and contracted, and only the rear portion of the seat surface 2b may be moved up and down. . Further, in the state shown in FIG. 12B, when the back twisted portion 62 (see FIG. 1) provided in the backrest portion 3 is driven and one of the left and right air bags 77 and 78 is inflated, the back muscles are stretched. The upper body can be twisted and massaged.

  FIGS. 12C and 12D show changes in the posture of the user when the leg of the user is stretched. When stretching such a leg part, the backrest part 2 of the chair type massage machine 1 is in an upright state, and the user is seated on the seat part 2. Next, when the operating device 91 (see FIG. 10) is operated by the user and an instruction to perform leg stretching is input, the right footrest 4a and the left footrest 4b are instructed by the control unit 90. The air bags 34 and 35 of the right crus support 10A and the left crus support 10B provided in (see FIG. 4) are inflated and supported so that the user's lower leg is grasped. Subsequently, in response to an instruction from the control unit 90, the seat surface operation unit 60 is driven, the air bags 73 and 74 are inflated, the rear portion of the seat surface 2b is raised, and the backrest portion 3 is tilted backward.

  By doing so, the back of the backrest 3 and the rear part of the seating surface 2b are raised so that the body of the user is bent in a supine state, but the lower leg of the user is supported. Therefore, in addition to the thighs of the legs, the back and abdominal muscles can be stretched. In addition, instead of the right crus support part 10A and the left crus support part 10B, or together with this, the right foot support part 11A and the left foot support part 11B may support the user's feet. Moreover, although the aspect which hold | maintains so that a to-be-treated person's leg may be hold | gripped by the expanded air bags 34 and 35 was demonstrated here, it is not restricted to this. For example, in the footrest 4, a cloth having a high friction coefficient is used on the surface of a cover (not shown) that wraps the right lower leg support 10A, the left lower leg support 10B, etc., and the friction between the lower leg of the user and the cover surface You may make it support so that a leg may not be displaced easily with force.

  Further, regarding the stretching of the leg portion, in addition to the mode described with reference to FIGS. 12C and 12D, the following can be performed. First, when the legs are stretched according to FIGS. 12C and 12D, the telescopic mechanism 50 is driven to adjust the right footrest 4a and the left side in accordance with the rising of the seating surface 2b and the back tilt of the backrest 3. The footrest 4b may be extended. Secondly, when the air bags 71 and 72 are inflated while the lower leg or the leg is supported and the front part of the seating surface 2b is raised, the leg part including the lower leg and the thigh part is stretched. At this time, the right and left footrests 4a and 4b may be extended by driving the telescopic mechanism 50 while supporting the lower leg or the foot.

  By the way, according to the chair type massage machine 1 which concerns on this Embodiment, in addition to what was shown in FIG.11 and FIG.12, stretch as shown in FIG. 13 can also be performed. FIGS. 13A and 13B show changes in the posture of the user when the legs of the user are stretched. In this case, the air bags 34 and 35 of the right lower leg support 10A and the left lower leg support 10B provided on the right footrest 4a and the left footrest 4b (see FIG. 4) are inflated so that the lower leg of the user is grasped. To be supported. Subsequently, in accordance with an instruction from the control unit 90, the air bladders 71 and 72 are inflated to raise the front portion of the seat surface 2b (that is, the seat surface 2b is tilted backward), and the air provided in the cushion portion 2c. The bag 2e is also inflated and pushes the user's thigh up.

  In this way, the knee side of the user's thigh is pushed upward while the patient's lower leg is supported so as to be gripped by the inflated air bags 34 and 35. Therefore, it is possible to stretch the thigh. Further, the thigh can be more effectively stretched by repeating the expansion and contraction of the air bag 2e with the seat surface 2b tilted backward.

  Furthermore, as shown in FIGS. 1 and 8, the chair type massage machine 1 according to the present embodiment includes a seating surface operating unit 60 including air bags 71 to 74, and the seating surface operating unit 60 allows the seating surface 2b. Since the height of the seating surface 2b is appropriately adjusted with respect to the users having various physiques, a suitable sitting comfort and a suitable massage can be realized. Can do.

  That is, when the chair type massage machine 1 is used as a sofa, the seat surface operating unit 60 is driven in accordance with the physique and preference of the person to be seated, and the height position of the seat surface 2b is adjusted, so that a suitable sitting Comfort can be secured. More specifically, in the initial state, the air bags 71 to 74 are in an exhausted state, and are used as they are when a relatively short person is seated, and when a relatively tall person is seated. Depending on the height of the person, the air bags 71 to 74 may be supplied with air to raise the seating surface 2b.

  In addition, when performing massage while sitting on the chair type massage machine 1, the range in which the mechanical massage mechanism 100 (see FIG. 1) provided in the backrest 3 can move up and down is limited. A relatively short user or a relatively tall user can make adjustments by raising or lowering the seating surface 2b so that the massage mechanism 100 is appropriately positioned with respect to the back of the upper body. In addition, the movable range of the massage mechanism 100 is generally set in the range from the shoulder to the waist, but when the seating surface 2b is raised, the massage mechanism 100 can reach further below the back. The treatment can also be performed on the buttocks of the user by the treatment element 101 included in the massage mechanism 100.

  Further, when the air bags 71 to 74 are supplied with air and the seat surface 2b is raised, the initial state is a relatively tall user who is in the movable range of the normal massage mechanism 100. Even if the treatment element 101 is not properly in contact with the shoulder, such a tall user can be obtained by exhausting the air from the air bags 71 to 74 and lowering the seat surface 2b. Even shoulder treatment can be performed appropriately.

  Furthermore, the treatment position can be optimized by raising or lowering the seat surface 2b by driving the seat surface operation unit 60, and not only the massage mechanism 100 but also the air bags 77 and 78 included in the back twisted portion 62 and the covering. Optimization of the positional relationship with the back of the user, optimization of the height of the grip 80 of the grip 63 from the seating surface 2b, optimization of the height of the user with respect to the armrest 5 or the forearm support 64, etc. It can be realized by driving the seating surface operating unit 60.

  In the above description, it is described that the lower leg support portions 10A and 10B and the foot support portions 11A and 11B “grip” the lower leg, the instep, the heel and the like by the inflation of the air bags 34, 35, and 44 to 48. However, “gripping” in this case does not mean only a state in which the corresponding body part is gripped to the air bags 34, 35, 44 to 48 so as to be completely fixed. In addition, a state in which a relative displacement occurs is also included. Eventually, “grabbing” a body part refers to a state where the body part is in contact with the body part in a manner that can limit displacement to some extent.
