Further, when the actuator 39 contracts and the footrest 5 is lowered most, the legs of the user seated on the seat 2 are bent at about 90 degrees at the knee, and the lower leg from the knee to the ankle is It will be in the state supported by the footrest 5 so that it may follow along a substantially perpendicular direction.

  Furthermore, the footrest 5 is provided with a telescopic mechanism 40. The telescopic mechanism 40 is not described in detail because a known configuration may be adopted, but the upper footrest 14 and the lower footrest 15 can be moved toward and away from the pivot 38 by the telescopic mechanism 40. In the footrest 5 according to the present embodiment, when the relative distance between the pivot 38 and the lower footrest 15 is changed, the relative distance between the pivot 38 and the upper footrest 14 is changed by a displacement that is half of the displacement. It has come to be. In addition, such expansion and contraction of the footrest 5 may be automatically executed according to an instruction from the control unit 50. However, in the footrest 5 according to the present embodiment, the footrest 5 may be lowered on the sole of the user. It expands and contracts according to the force that presses the side footrest 15.

  That is, when the lower footrest 15 is pushed with a predetermined force or more, the lower footrest 15 moves in a direction away from the pivot 38, and in conjunction with this, the upper footrest 14 moves in a direction away from the pivot 38. On the contrary, if the force with which the sole presses the lower footrest 15 is less than a predetermined value, the lower footrest 15 and the upper footrest 14 both move in a direction approaching the pivot 38 by the action of the separately provided urging means. . As described above, the upper footrest 14 and the lower footrest 15 are not forcibly expanded or contracted by the control unit 50, but a stopper (see FIG. Valid / invalid (not shown) can be determined by the control unit 50, and the extension and contraction movement of the footrest 5 as described above can be executed only when the control unit 50 disables the stopper.

[Remote controller]
FIG. 8 is an external view showing a configuration of a remote controller (hereinafter referred to as “remote controller”) 60 used when the user himself / herself operates the above-described operation means included in the chair type massage machine 1. As shown in FIG. 8, the remote controller 60 has a narrower lower part than the upper part, and the lower part of the narrower part is a grip part 61 held by the user. A cover 61 a that can be opened and closed is provided on the upper surface of the grip portion 61.

Further, by operating the button B ₁₄ , a rolling massage is performed in which the kneading balls 27 are pushed forward and moved up and down along the backrest portion 3. By operating the button B ₁₅ , the back vibration is performed. 8b is driven and vibration massage is performed on the waist and back. Further, when the button B ₁₆ is operated, voice guidance from a speaker provided on the chair type massage machine 1 or the remote controller 60, BGM, or the like is muted.

On the other hand, a plurality of buttons A _{01 to} A ₁₆ are also disposed on the wide upper portion of the remote controller 60 above the grip portion 61, and a display 62 is provided above the buttons A _{01 to} A _16. Yes. Even when these buttons A _{01 to} A ₁₆ are operated, a signal corresponding to the operated button is transmitted from the remote controller 60 to the control unit 50, and the control unit 50 preliminarily instructs each operation means based on the received signal. The set operation as shown below is executed.

Specifically, when the button A ₀₁ is operated, a series of massages mainly for recovery of fatigue of the whole body is performed over a predetermined time using all necessary operation means provided in the chair type massage machine 1. Performed (whole body medical course). When the button A ₀₂ is operated, the kneading balls 27 do not operate, and a series of air massages centering on acupressure on the whole body of the user using necessary ones of the air cells 7a to 7s is performed over a predetermined time ( Whole body air course). When button A ₀₃ is operated, a low-stimulus massage aimed at alleviating muscle stiffness and relieving muscle pain as a whole body massage suitable for young people from junior high to third grade Is executed (Young Program). When button A ₀₄ is operated, a program for massaging the whole body of the user in a short time is executed (quick course). This quick course will be described later.

  In the chair type massage machine 1 according to the present embodiment, when the young program is executed, the backrest 3 and the footrest 5 are temporarily returned to the standing state and the lowered state, which are the initial positions, and the backrest is lifted from this initial state. The part 3 is tilted backward for a predetermined time (for example, 3 seconds), the footrest 5 is raised for a predetermined time (for example, 3 seconds), and then massage by each operation means is started. As a result, it is possible to perform massage in a posture suitable for a young user, and the tilting angle of the backrest part 3 is not provided with an angle sensor by operating for a predetermined time after returning to the initial position once. And the raising position of the footrest 5 can be determined appropriately.

On the other hand, when the button A ₀₅ is operated, a massage by a method called “centripetal method” is performed (good morning course) for the purpose of refreshing the awakening and getting tired the previous day after getting up. When the button A ₀₆ is operated, a massage called “centrifugal method” is performed for the purpose of relieving fatigue and tension of the muscles before going to bed (sleeping course). When button A ₀₇ is operated, stretching is performed for the purpose of refreshing the whole body (stretch course). This stretch course will be described later. Further, when the button A ₀₈ is operated, the seat swing mechanism 31 is driven and the buttocks of the user are swung to the left and right to give a relaxed feeling to the user (fluctuation course).

When the button A ₀₉ is operated, the actuator 37 (see FIG. 5) can be expanded and contracted to adjust the reclining angle of the backrest portion 3, and when the button A ₁₀ is operated, the actuator 39 (see FIG. 5) is expanded and contracted. By moving, the raised position (lowered position) of the footrest 5 can be adjusted. Further, when the button A ₁₁ is operated, the air cell 28 is supplied and exhausted and the front and rear positions of the treatment mechanism 9 can be adjusted. By operating the button A ₁₂ , the kneading balls 27 are used before each course is executed. With respect to the shoulder position of the user automatically detected, the position of the user can be readjusted by the user himself / herself.

The button A ₁₃ is a main power operation button of the chair type massage machine 1. By operating this button, the main power is turned on / off, and by operating the button A ₁₄ , the chair type massage machine 1 in operation. All operations can be stopped in an emergency. Further, by operating the button A ₁₅ , all the air cells 7 a to 7 s can be exhausted and contracted, and by operating the button A ₁₆ , the pressure at the time of maximum expansion of all the air cells 7 a to 7 s. Adjustments can be made.

As described above, the user can operate the various operation means of the chair type massage machine 1 by operating the buttons A _{01 to} A ₁₆ and the buttons B _{01 to} B ₁₆ themselves. Explanations and guidance corresponding to the above are displayed on the display 62 of the remote controller 60.

[Operation control by control unit]
FIG. 9 is a table exemplifying a list of control items that can be executed by the control unit 50 for each operation means included in the chair type massage machine 1. The control items shown in FIG. 9 will be described in order from the top. First, the control unit 50 can set 11 target arrival positions with respect to the vertical position of the treatment mechanism 9. Each of these targets corresponds to a predetermined acupressure point on the back of the upper body of the human body, and 11 acupressure points are set in a range from the vicinity of the shoulder to the vicinity of the waist. Further, when the treatment mechanism 9 is moved up and down, the control unit 50 can set the moving speed in seven stages from the lowest speed (SPD1) to the highest speed (SPD7).

  Regarding the massage massage operation, the target width for the distance between the left and right massage balls 27, 27 provided in the treatment mechanism 9 can be set in three stages (wide, narrow, medium), and the number of massages can be set arbitrarily. Yes. Further, the stagnation speed can be set in seven stages (SPD1 to SPD7), and the stagnation motor can be set to rotate in the normal rotation or reverse direction. When the rotation direction of the kneading motor is normal rotation, the kneading balls 27 operate so as to squeeze the treatment site from the outside to the inside. .

  With respect to the massage operation with the hit 1 which is a hit with a normal cycle by the kneading balls 27, the operation time can be arbitrarily set (in this embodiment, the “operation time” has a relatively short time. The operation time is expressed as “short”, the long operation time as “long”, and the intermediate operation time as “medium”. The same applies to the “effective time” (see FIGS. 13 and 14). ), The hitting operation can be set in seven stages (SPD1 to SPD7). Regarding the seat swing operation by the seat swing mechanism 31, the target reaching position of the seat surface body 10 can be set in three stages (origin, left end, right end), and the operation time of the seat swing mechanism 31 (in other words, the motor 33) can be arbitrarily set. The operation speed can be set in seven stages (SPD1 to SPD7).

  With regard to the massage operation of the kneading balls 27 by the kneading balls 27, the rotation direction of the kneading motor can be set between normal rotation and reverse rotation. Can be set. Further, the control unit 50 can arbitrarily set the number of hits with respect to the massage operation with the hit 2 that is hit at a speed higher than usual.

  With respect to the massage operation in which the kneading balls 27 are massaged and struck at the same time, the number of executions can be arbitrarily set for each of the three patterns set in advance for the combination mode of stagnation and tapping. In addition, it is possible to arbitrarily set the duration (effective time) for massage operation that simultaneously massages and back vibe, and it is possible to arbitrarily set the duration (effective time) for massage operation only for the back vibrator. ing.

  With respect to the reclining operation for rotating the backrest part 3, the longest operation time can be arbitrarily set, and ascending (standing) and descending (backward tilt) can be set as the operating direction. Similarly, with respect to the pivoting operation of the footrest 5, the longest operation time can be arbitrarily set, and ascending and descending can be set as the operation direction.

  Moreover, about the operation | movement (foot slide) of the expansion-contraction mechanism 40 of the footrest 5, it can set arbitrarily about the effective time when expansion / contraction movement is executable, and it is operation | movement regarding the position (push adjustment) of the treatment mechanism 9 in the front-back direction. The direction can be set by pushing and pulling. Further, the control unit 50 can select and set a target air cell and the timing of air supply / exhaust from a plurality of courses set in advance with respect to the air supply / exhaust to the air cells 7a to 7s.

  The chair-type massage machine 1 can perform various operations by controlling the operation of each operation means of the chair-type massage machine 1 by the control unit 50. Although not shown in FIG. 9, the driving time of the seating vibrator 8a can be arbitrarily set by the control unit 50.

  Next, several treatments for the user who can be performed by the chair type massage machine 1 as described above will be specifically described.

[Stretch operation]
FIG. 10 is a schematic diagram showing a change in posture of the user when the user who is seated on the seat portion 2 and whose upper body is supported by the backrest portion 3 is stretched to extend the spine. First, the chair-type massage machine 1 is in a state in which the backrest part 3 stands up and the footrest 5 rises substantially horizontally. At this time, the user rises up and the legs rise from the thighs to the toes. Is in a state of extending straight forward ("first posture" in FIG. 10). Further, the air cells 7 l and 7 o provided on the footrest 5 are inflated so that the ankle and the tip of the foot are held by the footrest 5.

  Next, while holding the ankle and the toe, the backrest 3 is tilted backward and the footrest 5 is lowered. As a result, the user's upper body tilts backward, and the lower leg is bent downward relative to the thigh with the knee as the base point, and the whole body leans backward ("second posture" in FIG. 10). It is said. As a result, the user's upper body is warped backwards (as viewed from the user), the spine is stretched and stretched.

  Note that the back tilting operation of the backrest 3 and the lowering operation of the footrest 5 do not have to be performed at the same time. For example, the backrest 3 can be stretched by tilting the backrest 3 after the footrest 5 is lowered. In this case, the leg of the user is bent near the knee by the lowering of the footrest 5, and the backrest 3 is tilted backward while the lower leg is held, and the upper body of the user is overhead. Since it tries to shift its position in the direction, it can be stretched so that the whole body is stretched. In addition, due to friction between the front surface (back surface) of the backrest 3 and the back of the user who is in contact with the backrest, the displacement of the upper body toward the lower leg is restricted, and the upper body is positioned above the head. It is easy to shift and can stretch the whole body.

  Further, as the backrest part 3 is tilted backward, the air cell 7p corresponding to the neck, the air cell 7g corresponding to the shoulder, the air cells 7d to 7h corresponding to the arm part, and the air cell 7b corresponding to the side part of the hip part, By inflating any or all of them, the upper body (neck, shoulders, arms) and buttocks of the user can be held and the displacement of the upper body toward the lower leg can be more controlled, further improving the stretch effect Can be achieved.

  FIG. 11 is a schematic diagram showing a posture change of the user when another stretch that extends the user's spine is performed. In FIG. 11, the first posture and the second posture are the same as those described in FIG. In the stretch shown in FIG. 11, the treatment lies on its back by inflating the air cell (pressing portion) 7 c provided in the lower part of the backrest 3 from the state where the user is in the second posture. Press to push the vicinity of the waist of the person upward. Thereby, the user is in a posture to bend back so that the upper body is further warped backward (“third posture” in FIG. 11), and the stretch effect is improved.

  Here, the air cell 7c is inflated to push up the vicinity of the lumbar region, but instead of the air cell 7c, the air cell 28 disposed in the rear thereof is inflated with the treatment mechanism 9 positioned in the vicinity of the lumbar region, so that the treatment mechanism 9 It is also possible to push up the vicinity of the lumbar region by the kneading balls 27 by pushing out to the user side. Further, at the same time as pushing up the vicinity of the waist by the kneading balls 27, the treatment mechanism 9 can be driven to cause the kneading balls 27 to perform a kneading operation. Can also be applied.

  Further, if the air cell 7c (or the air cell 28) is inflated and contracted (slightly vibrated) in a short cycle while the user is in the third posture, further improvement of the stretching effect can be expected. For such fine vibration, a vibration operation by driving the back vibrator 8b may be employed, or a tapping operation or a kneading operation by the kneading balls 27 may be employed. Moreover, when pushing up the waist which makes the user take the third posture, any or all of the above-described air cells 7d to 7h, 7p may be inflated to hold the upper body and the buttocks, and thereby the side of the body Since the central part of the body in the left-right direction is pushed up while being held, further improvement of the stretch effect can be expected.

  In addition, the chair type massage machine 1 according to the present embodiment includes the seat swing mechanism 31 that swings the seat body 10 to the left and right. Therefore, prior to the stretching operation shown in FIGS. The shaking mechanism 31 may be operated to swing the user's buttocks from side to side for a certain period of time. Such swinging of the buttocks has the effect of relaxing the user mentally and physically like shaking in an easy chair or hammock, so the relaxed state where the user is weakened by performing before stretching It is possible to improve the effect of the subsequent stretch.

  FIG. 12 is a schematic diagram showing a posture change of the user when another stretch is performed to extend the back muscle of the user. In the example shown in FIG. 12 (a), the backrest 3 is tilted rearward and the footrest 5 is lowered, and the ankles and toes are held by the expansion of the air cells 7l and 7o. It is in the same state as the two postures. And in this state, the left and right air cells 7c provided at the lower part of the backrest 3 are inflated with one of the left and right air cells 7c being contracted, thereby pushing up the waist of the user from either the left or right, Stretching with the upper body twisted. Alternatively, the left and right air cells 7c may be expanded and contracted so that the timings of expansion and contraction are opposite to each other and stretched so that the upper body is sequentially twisted rightward and leftward.

  In the example shown in FIG. 12 (b), the seat swing mechanism 31 is driven from the same state as the second posture of FIG. 10, and the seat surface body 10 is reciprocated to the left and right to place the buttocks of the user to be placed thereon. Is swung left and right. Such swinging of the heel portion to the left and right can also be realized by alternately expanding and contracting the air cells 7b and 7b disposed on the left and right so that the expansion and contraction order is reversed. In addition, you may press so that a collar part may be pushed up by making the air cell 7a provided in the seat part 2 into the expansion | swelling state. Further, the air cell 7c may be in an expanded state simultaneously with the swinging of the buttocks, so that the stretching by the third posture (see FIG. 11) and the swinging of the buttocks may be performed in combination. As a result, the buttocks are swung in such a posture that the user looks back, and an improvement in the stretch effect can be expected. In this way, the control unit 50 independently controls the stretching by the backward tilting of the backrest part 3, the swinging of the buttocks by the driving of the seat swing mechanism 31, and the pushing up of the waist by the air cell 7c or the treatment mechanism 9. By performing the combination appropriately, it is possible to improve the stretch effect for the user.

  In the example shown in FIG. 12C, in addition to the posture of the second posture shown in FIG. 10, the vicinity of the wrist of the arm portion raised so as to be aged is held. By adopting such a posture, the whole body of the user can be further extended, and an improvement in the stretch effect can be expected. As a means for holding the vicinity of the wrist, a concave member opened forward for wrist reception may be attached to both sides of the upper portion of the backrest portion 3 so as to support the wrist portion. You may make it hold | maintain a wrist by the means of. Further, as to the order of holding the wrist and the back tilting part 3 backward, if the wrist is first held on the head and then the back rest part 3 is tilted backward, a further stretch effect can be obtained. . Furthermore, the stretching operation shown in FIGS. 10, 11, 12A, and 12B may be combined with the stretching operation shown in FIG.

  In the stretch illustrated in FIG. 10 to FIG. 12 described above, the footrest 5 is lowered until the footrest 5 is substantially vertical, whereby the lower leg portion of the user is bent at a substantially right angle with respect to the thigh portion and However, the footrest 5 is not necessarily adjusted to the lowest position. That is, the posture may be such that the footrest 5 is positioned slightly above this, and the legs of the user are gently bent near the knee.

  In addition to stretching in the above-described manner, a rolling massage that raises and / or lowers the treatment mechanism 9 along the backrest 3 in a state where the user is in the second posture shown in FIG. This may be done, and this can also be used to stretch the back. In particular, effective stretching can be realized by rolling massage that raises the treatment mechanism 9 from a position corresponding to the vicinity of the waist. Further, during the reclining operation in which the backrest 3 tilts backward from the standing state, the air cell 28 is inflated to press the massaging balls 27 against the back of the user, and the treatment mechanism 9 is moved from a lower position corresponding to the vicinity of the waist. It may be moved up or moved down from an upper position. This also makes it possible to realize a stretch that stretches the back of the user.

[Quick Course]
13 and 14 are tables showing specific operation control by the control unit 50 in the quick course mentioned in the description of FIG. 8, and the horizontal axis represents steps 0 to 42 executed in time series. Is shown. In the quick course illustrated here, a predetermined course A is executed in steps 3 to 19, another course B is executed in steps 20 to 26, and a combination of stretch A and stretch B is intermittent in steps 28 to 39. Finally, course C is executed at step 41.

  Specifically, as shown in FIG. 13, starting from the initial state of step 0, the treatment mechanism 9 moves in the pushing direction for a short time (effective time: “medium”) (step 1). Next, the treatment mechanism 9 located at the lowest position rises one step at a time at the highest speed (SPD7) in steps 2, 4, 6 and 8 and reaches the position corresponding to the fourth acupressure point 8 from the bottom. Thereafter, in steps 12, 14, 16, and 18, the speed is lowered one step at a time at the maximum speed (SPD7) and returned to the lowest position again. In the meantime, the kneading balls 27 perform a massage massage (forward rotation: once each) in steps 3 and 5 in which the treatment mechanism 9 is stopped without moving up and down, and in step 7 the kneading and tapping are linked. In step 9, a massage in which the hit 1 at the lowest speed and hand massage (normal rotation: 1 time) are performed is performed, and in step 11, a massage of hand massage style (normal rotation: 1) is performed. Only), and in steps 13, 15, 17, and 19, massage by brushing is executed. Note that the sanding is an operation of swinging the kneading balls 27 left and right a predetermined number of times to point the back or waist of the user. In addition, during the period from the start of the hand massage massage in Step 3 to the completion of the massage massage in Step 19, the pressure massage by the air cells 7a to 7s set in advance as the course A is also executed.

  Next, during steps 20 to 26, a pressure massage in another form by the air cells 7a to 7s set in advance as the course B is executed. During this time, the treatment mechanism 9 corresponds to the fourth acupressure point 8 from the bottom. Position (step 20), position corresponding to the lowermost acupressure point 11 (step 21), position corresponding to the uppermost acupressure point 1 (step 22), position corresponding to the lowermost acupressure point 11 (step 23) ), The position corresponding to the fourth acupressure point 8 from the bottom (step 24), the position corresponding to the lowermost acupressure point 11 (step 25), and the position corresponding to the uppermost acupressure point 1 (step 26). And move sequentially. The kneading balls 27 perform massaging massage (forward rotation) at the minimum speed (SPD1) during steps 20 to 23, and at the same time between steps 20 to 22 the massage of tapping 1 at the minimum speed (SPD1). Execute. Further, during steps 23 to 26 after the hit 1 massage, vibration massage by the back vibrator 8b is executed.

  When the execution of a series of massages by the air cells 7a to 7s, the kneading balls 27, and the back vibrator 8b is completed in this manner, the operation for stretching the whole body of the user is performed from step 27 to step 41. . Note that the number of times can be set for greasing, hand-gripping, rubbing, rubbing and hitting (see FIG. 9). Of course, this number can be set not only to 1 but also to an arbitrary numerical value.

  Specifically, as shown in FIG. 14, first, during steps 27 to 40, the footrest 5 can be expanded and contracted (foot slide: effective), and in step 28, stretch A is executed. As this stretch A, the operation | movement which hold | maintains an ankle by expansion | swelling of the air cell 7l is set. In the next step 29, the footrest 5 moves down for a moderate time (operation time: “medium”), and the backrest 3 tilts backward for a short time (operation time: “short”). When the descending movement of the footrest 5 is completed, the backrest 3 is further tilted backward by an intermediate time (operation time: “medium”), and the backrest 3 is most tilted backward. In addition, the stretch B is executed during the operation of the backrest 3 and the footrest 5 in Steps 29 and 30 and in the next Step 31 in which the backrest 3 and the footrest 5 are stopped. As this stretch B, the operation | movement which hold | maintains a foot tip by expansion | swelling of the air cell 7o is set.

  Accordingly, between steps 29 to 31, the backrest 3 is tilted backward and the footrest 5 is lowered while the toes are held, so that the user is in the second posture described with reference to FIG. 10. The same state can be experienced and the stretch that stretches the back muscles can be experienced. In this stretching operation, the back tilting operation of the backrest 3 is performed for a short time at the same time as the footrest 5 is lowered, and the step 30 is performed for a medium time when the footrest 5 is stopped. Since the process is divided into two steps, the burden on the user is small, and it is suitable as the first thing to be performed in a series of stretching operations.

  In the next step 32, the backrest 3 is tilted forward for a long time (operation time: “long”) and the footrest 5 is raised for a long time (operation time: “long”). Thereby, the user is in a state similar to the first posture described with reference to FIG. 10, and is temporarily released from the stretched state.

  Next, after the ankle is held again by the expansion of the air cell 7l in step 33, the air cell 7o expands and holds the toe in steps 34 to 35. At the same time as holding the toes, in step 34, the backrest 3 tilts backward for a moderate time (operation time: “medium”) and the footrest 5 descends for the same amount of time. Is the same posture as the second posture (see FIG. 10). In this way, in the second stretching operation, the back tilting operation of the backrest 3 and the lowering operation of the footrest 5 are performed at the same time for the same amount of time, so the user is slightly more than during the first stretching operation. A strong stretch feeling can be obtained.

  Thereafter, in step 36, as in step 32, the backrest 3 tilts forward and stands for a long time (operation time: “long”) and the footrest 5 rises for a long time (operation time: “long”). . Thereby, the user is released from the stretched state.

  Subsequently, after the step 37 in which none of the backrest part 3, the footrest 5, and the air cells 7a to 7s operate, the ankle is held by the stretch A (step 38), and then the foot is held by the stretch B (step 39). To do. In this step 39, the backrest 3 is tilted backward for a medium time (operation time: “medium”) and the footrest 5 is lowered for the same time simultaneously with the holding of the toe, Becomes a posture similar to the second posture (see FIG. 10), and a slightly strong stretch feeling can be obtained.

  Next, in step 40, as in steps 32 and 36, the backrest 3 tilts forward for a long time (operation time: “long”), and the footrest 5 stands for a long time (operation time: “long”). To rise. Thereby, the user is released from the stretched state. By completing this step 40, the stretching operation of the chair type massage machine 1 for the user is completed. Then, after the stretching operation is completed, the air cell 7a to 7s is appropriately expanded and contracted so as to press and treat the appropriate portion of the user, and the seat swing mechanism 31 is driven at the maximum speed (SPD7), thereby receiving the user. The user's buttocks are swung left and right so that the user can feel relaxed (step 41). Finally, the seating body 10 is returned to the origin position (step 42).

  As explained above, by stretching the whole body after pressure massage such as massage or hitting, the muscles of the user's whole body can be softened, and after the stretching, the seat swing mechanism 31 is driven to swing the buttocks By doing so, the muscles of the user can be further softened.

  In addition, although the example which performs a stretching operation | movement intermittently 3 times was shown in FIG. 14, it may be 2 times or 4 times or more. Further, after the backward tilting operation of the backrest portion 3 is completed, as described with reference to FIGS. 11 and 12, the waist is pushed upward, the upper body is twisted, and the buttocks are swung left and right. In addition, it goes without saying that the backrest 3 may be tilted backward with the wrist held above the head. Furthermore, in the above-described stretching operation, the case where the ankle and the toe are held has been described, but only the ankle or the toe may be held, or the calf may be held by the air cells 7j and 7k.

[Other configurations of chair type massage machine]
FIG. 15 is a side view showing another configuration of the chair type massage machine capable of executing stretching for stretching the back of the user. A chair-type massage machine 70 shown in FIG. 15 has substantially the same configuration as the chair-type massage machine 1 described above, except that the upper surface of the seat portion 2 is configured to be movable up and down.

  More specifically, the seat part 2 of the chair type massage machine 70 is configured such that a seat cushion 2a that stably supports the buttocks and thighs of the user is disposed on a seat frame 13 that forms a skeleton. Has been. Air cells 71a and 71b are provided between the seat frame 13 and the seat cushion 2a at the front and rear portions. In the present embodiment, these air cells 71a and 71b are expanded and contracted by supplying and discharging air from the air supply / exhaust device 51 shown in FIG. That is, the air cells 71a and 71b can be lifted upward by a predetermined distance while maintaining the contracted posture.

  According to the chair type massage machine 70 having such a configuration, the backrest 3 is tilted backward when the user is seated, and the air cells 71a and 71b are inflated with the footrest 5 positioned below. Thus, the rear upper surface of the seat portion 2 is positioned above the lower upper surface of the backrest portion 3 and can be pressed so as to push up the vicinity of the buttocks of the user who lies on his back. Thus, as shown in the third posture of FIG. 11, the user is stretched in such a posture that his / her upper body is warped backward (in this case, downward).

  In addition, although the case where the seat cushion 2a ascends while maintaining its posture has been described above due to the expansion of the air cells 71a and 71b, the posture of the seat cushion 2a may be slightly changed. For example, the relative position (vertical position) of the rear part with respect to the front part on the upper surface of the seat cushion 2a may rise due to the expansion of the air cells 71a and 71b. Alternatively, the front air cell 71a may be omitted to include only the rear air cell 71b, and the rear air cell 71b may be expanded to raise only the rear portion of the seat cushion 2a close to the waist. In the end, it is only necessary to form a step at the boundary portion between the seat portion 2 and the backrest portion 3 so that the upper surface of the seat portion 2 is located above the upper surface of the backrest portion 3. By doing in this way, it can be stretched so as to turn the user back.

  FIG. 16 is a side view showing still another configuration of a chair-type massage machine that can execute stretching to stretch the back of the user. The chair-type massage machine 80 shown in FIG. 16 has substantially the same configuration as the chair-type massage machine 1 already described, but the upper surface of the backrest part 3 tilted backward is configured to be movable up and down. Is different.

  More specifically, the backrest 3 of the chair type massage machine 80 is provided with a back cushion 3b that stably supports the upper body of the user on the front side of the back frame 29 (only a part of which is shown) constituting the skeleton, Further, the back portion of the back frame 29 is covered with the backrest case 3c. An air cell 81 is provided between the lower portion of the back frame 29 and the back cushion 3b. In the present embodiment, the air cell 81 is expanded and contracted by supplying / discharging air from the air supply / exhaust device 51 shown in FIG. 5, and the lower portion of the back cushion 3b is separated from the back frame 29 by expanding. It can be moved in the direction.

  According to the chair type massage machine 80 having such a configuration, when the user is seated, the backrest part 3 is tilted backward, and the footrest 5 is inflated with the air cell 81 in a state of being positioned below, At the boundary portion between the seat portion 2 and the backrest portion 3, a step is formed so that the lower upper surface of the backrest portion 3 is located above the rear upper surface of the seat portion 2, and the user who lies on his back Can be pressed so as to push up the vicinity of the lower back. Thus, as shown in the third posture of FIG. 11, the user is stretched in such a posture that his / her upper body is warped backward (in this case, downward).

  In addition, in the stretch shown in FIG.15 and FIG.16 mentioned above, it is also possible to expand the air cells 7i-7o provided in the footrest 5, and to support the leg part of a user. Then, by moving the seat cushion 2a or the back cushion 3b as described above when the lower leg is supported in this manner, it is possible to expect an improvement in the stretching effect for the user.

  In the above description, the case where the stretch is performed while the footrest 5 is lowered has been described. However, the footrest 5 does not necessarily have to be lowered. For example, the footrest 5 is raised as shown in FIG. You may make it move the seat cushion 2a or the back cushion 3b in the made state. Even in this case, it is possible to expect a stretch effect that turns the upper body of the user back.

  Further, by combining the configuration shown in FIG. 15 and the configuration shown in FIG. 16, the user can be stretched without forming a step at the boundary portion between the seat portion 2 and the backrest portion 3. Is possible. For example, the rear air cell 71b is expanded in a state where the front air cell 71a of the seat portion 2 is contracted, and the air cell 81 provided in the backrest portion 3 is expanded. As a result, the seat cushion 2a is tilted so that the rear portion is positioned higher than the front portion, and the lower portion of the back cushion 3b is raised. As a result, no step is formed at the boundary portion between the seat portion 2 and the backrest portion 3, but the vicinity of the user's buttocks or waist is pushed upward, so that the user is stretched. be able to. Even in this case, a certain stretch effect can be expected even when the footrest 5 is in the lowered state shown in FIG. 7B. However, when the footrest 5 is in the raised state shown in FIG. The stretch effect can be expected.
