A pin (203) protruding from 201) is slidably fitted. Between the two pressing elements (202) and (302), an interval is formed in which the shoulder muscles of the user can be sandwiched with a sufficient margin.

  As shown in FIG. 3, the pressing member (202) of the first treatment finger (200) may pivotally support the flat roller body (202a) on the first rotation lever (201). As shown in FIG. 10, the wide roller body (202 b) is turned sideways and pivotally supported by the first rotation lever (201) so that the masseur's fingers are spaced apart from the second finger to the fifth finger. A close resentment can be obtained.

  If the second treatment finger (300) is formed to be about the width of the first finger by slightly raising the tip of the second rotation lever (301) inward in order to approximate the masseur's itchiness by the first finger. Good.

  In the embodiment, as shown in FIG. 15, when the distance between the free ends of the swing levers (100) and (100) is fully opened (the free end of the swing lever is at the uppermost position), FIG. As shown, even when it is fully closed (at this time, the free end of the swing lever is at the lowest position), it is lower than the width center L1 of the presser (202) of the upper first treatment finger (200). The size of the pressers (202) and (302) and the left and right swings of the swing lever (100) to be described later so that the width center L2 of the presser (302) of the second treatment finger (300) is located inside The width is determined. This is close to the masseur's itchiness in view of the fact that the position of the first finger on the lower side is located inside the width center of the finger row below the second finger on the upper side when the masseur massages the shoulder. Because.

  The first treatment finger (200) is linked to a rotation angle restricting means (401) for restricting a rotation angle range of the first treatment finger (200) relative to the swing lever (100). The rotation angle restricting means (401) of the embodiment is formed by pivotally connecting a rear upper end of the first rotation lever (201) and the main chassis (21) with a rod (402).

Is configured.

  As shown in FIG. 14, when the free ends of the left and right swing levers 100, 100 are lowered while narrowing each other, the rod 402, the first treatment finger 200, is stretched, and the first treatment is performed. The finger (200) is rotated counterclockwise with respect to the swing lever (100) about the support shaft (102). At this time, the pin (203) on the first treatment finger (200) pushes the second treatment finger (300) and rotates the second treatment finger (300) clockwise around the pin (103). In the state of FIG. 14, the presser (202) of the first treatment finger (200) reaches the lowest position, the presser (302) of the second treatment finger (300) advances maximum, and both pressers (202) ( 302) is the smallest. This minimum interval is an interval at which the shoulder muscles of the user can be properly grasped.

  As shown in FIG. 13, when the left and right swing levers (100) (100) are lifted while their free ends are widened, the rod (402) pulls the first treatment finger (200) rearward, 1 The treatment finger (200) is rotated clockwise around the support shaft (102) with respect to the swing lever (100). At this time, the pin (203) on the first treatment finger (200) pushes the second treatment finger (300) and rotates it counterclockwise around the pin (103). In the state of FIG. 13, the pressing element (202) of the first treatment finger (200) reaches the highest position, the pressing element (302) of the second treatment finger (300) is retracted to the maximum, and both pressing elements (202) ( 302) is the largest. This maximum interval is an interval at which the grasping of the shoulder of the user can be released to a state with a little margin.

  As described above, the swing lever (100) (100) is in a state of spreading outward, and is eccentrically attached to the stagnation shaft (40), and is prevented from rotating by the rod (55). When the kneading shaft (40) is continuously rotated in one direction, the free ends of the swing levers (100) and (100) move left and right, up and down, and back and forth. As a result, the first treatment finger (200) and the second treatment finger (300) are also swung to the left and right to rub the affected area of the user. This is performed in combination with the (300) approaching / separating motion.

  As shown in FIG. 15, the first treatment fingers (200) and (200) are located from the shoulder to the neck of the user in a state where the left and right first treatment fingers (200) and (200) are fully opened. As shown, the neck of the user can be slightly pressed while the left and right first treatment fingers (200) and (200) are closest to each other.

  As shown in FIGS. 4 and 5, eccentric cams (53) and (53) whose phases are shifted from each other by 180 degrees are pivotally supported on the hitting shaft (50), and both eccentric cams (53) and (53) are The swing levers (100) and (100) are connected to the rear end of the swinging shaft (40) side via universal joints (54) and (54) and rods (55) and (55).

  When the tapping motor (51) is continuously rotated in one direction, the swing levers (100) (100) are moved to the squeezing shaft (100) via the rods (55) (55) eccentrically connected to the tapping shaft (50). The tip is swung mainly around 40), and the massage is mainly performed with the first treatment finger (200). When the kneading shaft (40) and the striking shaft (50) are rotated simultaneously, the swing lever (100) repeats reciprocating movement in which the movements of the front / rear stroke, the vertical stroke, and the left / right stroke are combined.

  The massage unit (20) is provided with a protrusion mechanism (60) for moving the massage unit (20) back and forth as shown in FIGS. Examples of the protruding mechanism (60) include the following crank mechanism (61) and link mechanism (70).

  As shown in FIGS. 5 and 6, the crank mechanism (61) includes a crankshaft (62) disposed in front of the stagnation shaft (40) and upper rollers (65) (65) (see FIG. 6). Crank pins (64) and (64) (see FIG. 5) that are rotatably fitted are connected by crank arms (63) and (63). The crankpins (64) and (64) are eccentric with respect to the crankshaft (62), so when the crankshaft (62) is rotated, the crankpins (64) and (64) are centered on the crankshaft (62). Draw a circumferential orbit. In the illustrated embodiment, the crankshaft (62), the crank arms (63) (63), and the crankpins (64) (64) are composed of a single metal rod, as shown in FIG. The crankshafts (62) and (62) are pivotally supported on the main chassis (21) by bearings (62a) and (62a).

  As shown in FIG. 3, support pieces (22a) and (22a) having bearings (22b) and (22b) are vertically projected on the auxiliary chassis (22), and the bearings (22b and 22b) are provided on the auxiliary chassis (22b). As shown in FIGS. 3, 4 and 6, a protruding screw shaft (67) is pivotally supported. The upper end of the screw shaft (67) is connected to a projecting motor (69) via a speed reduction means (68) comprising a pulley and a belt.

  A nut (71) is screwed onto the protruding screw shaft (67). The nut (71) can be made of resin, and a link mechanism (70) is connected to the resin nut (71) as shown in FIGS. The link mechanism (70) can be composed of a link piece (72) and a link piece (78).

  In the following, an example in which the link piece (72) is composed of a first link piece (73) and a second link piece (75) that are slidably connected to each other so as to be stretchable in the longitudinal direction will be described. To do.

  The first link piece (73) is pivotally supported by a resin nut (71) so as to be tiltable in the front-rear direction, and a slide shaft (74) projects in the vicinity of the base end side of the first link piece (73). It is installed.

  The second link piece (75) is composed of a pair of members that sandwich the first link piece (73) from both sides, and has a long hole (76) in the longitudinal direction. The slide shaft (74) of the first link piece (73) is slidably fitted in the long hole (76) of the second link piece (75).

  Furthermore, as shown in FIG. 6, a shaft (75a) projects from the tip of the second link piece (75), and a spring (77) is stretched between the slide shaft (74). Has been. The spring (77) biases the second link piece (75) toward the resin nut (71). When the second link piece (75) is unloaded, the spring (77) The link piece (75) is most drawn toward the resin nut (71).

  A third link piece (78) is pivotally supported on the shaft (75a) of the second link piece (75). The third link piece (78) bends forward at the center, the tip is fixed to the crankshaft (62), and the third link piece (78) and the crankshaft (62) rotate together.

  When the resin nut (71) is positioned above the protruding screw shaft (67), the third link piece (78) is drawn toward the second link piece (75), and the massage unit (20) ( The main chassis (21) is in the most inclined position (see FIGS. 1 and 6).

  From this state, when the protruding screw shaft (67) is rotated and the resin nut (71) is moved downward as shown in FIG. 7 (in the direction of arrow A in FIG. 7), the resin nut (71) Along with the downward movement, the second link piece (75) pulls the pivot part with the third link piece (78) downward, and the third link piece (78) rotates around the crankshaft (62). To do. Since the third link piece (78) and the crankshaft (62) are fixed, the crankshaft (62) rotates together with the third link piece (78).

  The crank pins (64) and (64) at both ends of the crankshaft (62) can be moved only along the guide rails (14) and (14) by the rollers (65) and (65), and do not move back and forth. Due to the rotation of the crankshaft (62), the massage unit (20) tilts about the vertical rotation shaft (24). Since the vertical rotation shaft (24) is provided below the massage unit (20), as shown in FIG. 2, the first treatment finger (200) and the second treatment finger are moved by the tilting of the massage unit (20). The swing lever (100) including (300) protrudes forward (indicated by arrow B in FIG. 7).

  In the state shown in FIG. 2, when the protruding screw shaft (67) is rotated in the reverse direction, the resin nut (71) moves upward, and conversely, the massage unit (20) is retracted and the upper and lower treatment fingers ( The swing lever (100) including 200) and (300) is pulled back into the backrest (12) (see FIG. 1). In the retracted state, only the presser (202) of the first treatment finger (200) is in a position where it can be pressed against the user on the backrest (12).

  By adjusting the rotation of the protruding screw shaft (67), that is, the position of the resin nut (71) with respect to the protruding screw shaft (67), the protruding amount of the massage unit (20) can be adjusted.

  The amount of protrusion of the massage unit (20) can be detected by the amount of protrusion detection means (79). As the protruding amount detecting means (79), for example, as shown in FIG. 6, a variable resistor (79a) contacting the third link piece (78) is provided, and the third resistor is provided by the variable resistor (79a). What is necessary is just to measure the change of the resistance value with the rotation angle of the piece (78).

  Since the crankshaft (62) also rotates integrally with the third link piece (78), the protruding amount detection means (79) may be provided on the crankshaft (62).

  All control of the chair type massage machine is performed by the control unit (90) shown in FIG. The control unit (90) is disposed at an appropriate position of the massage machine, and includes a drive circuit (not shown) for controlling the motors (26) (41) (51) (69), a memory storing a massage program, and the like. Yeah. The massage operation described below is also executed from a program stored in the control unit (90).

  Next, the massage operation of the present invention will be described.

  As shown in FIG. 13, the massage unit (20) is protruded forward from the backrest (12), and the presser (202) of the first treatment finger (200) and the presser (302) of the second treatment finger (300). ), The first treatment finger (200) is positioned slightly above the shoulder of the user and the second treatment finger (300) is against the back of the shoulder. ) And the height position are adjusted.

  In this state, the stagnation motor (41) is driven to rotate the stagnation shaft (40).

  Both swing levers (100) swing back and forth around the stagnation shaft (40) while applying left and right movements. The first treatment finger (200) and the second treatment finger (300) on the swing lever (100) also swing, but the rod (402), which is the motion conversion means (400), is connected to the swing lever (100). When the free end rises, the first treatment finger (200) is pulled rearward and rotated clockwise with respect to the swing lever (100) about the support shaft (102).

  As shown in FIG. 14, when the free end of the swing lever (100) is lowered, the rod (402) pushes the first treatment finger (200) forward, and the first treatment finger (200) is supported on the spindle ( 102) is rotated counterclockwise with respect to the swing lever (100).

  As described above, the presser (202) of the first treatment finger (200) is at the high position while the free end of the swing lever (100) is in the raised position, and the presser ( 302) is in the retracted position, and the distance between the pressers (202) (302) is the maximum (see FIG. 13), and the first treatment finger (200) is in a state where the free end of the swing lever (100) is in the lowered position. ) Presser (202) is in the low position, and the presser (302) of the second treatment finger (300) is in the advanced position, so that the opening interval of the pressers (202) (302) is minimized (FIG. 14). For this reason, when the kneading shaft (40) makes one rotation, the presser (202) on the shoulder and the presser (302) on the back of the shoulder approach and are separated from each other.

  The shoulder muscles are grasped when the two pushers (202) and (302) approach each other, and the grips are released when they are separated from each other. This operation is the same as the movement of the masseur grabbing and shouldering the shoulder, and can provide a massage effect that cannot be obtained by hitting with a conventional massage machine or rubbing.

  Particularly in the present invention, the movement of the massage unit (20) is added to the approaching and separating movements of the two pressing elements (202) and (302) as described below to obtain a more effective grip massage massage. I am doing so.

  Minimize the distance between the presser (202) of the first treatment finger (200) and the presser (302) of the second treatment finger (300) and temporarily stop the massage motor (41) while gripping the affected area. Then, the vertical motor (26) is driven to raise the massage unit (20) by 2 to 3 cm. That is, the affected part is picked up. Next, stop and hold the vertical motor (26), hold the state that has been grabbed, restart the pinching motor (41) after 2 to 3 seconds, widen the interval between the two pushers (202) (302), Release the grip state. Then, the vertical motor (26) is rotated in the reverse direction, and the massage unit (20) is lowered with the distance between the two pressing elements (202) and (302) being widest, and returned to the original position. Then, by repeating the operation of holding the affected part again by narrowing the distance between the two pressing elements (202) and (302), the affected part can be repeatedly picked up, and a more effective grasping massage can be realized.

  In this description, the massage unit (20) is lifted after the interval between the two pressing elements (202) and (302) becomes the smallest, but when the interval between the two pressing elements (202) and (302) is becoming narrower The massage unit (20) may start to rise.

  Also, instead of raising the massage unit (20) when the interval between the two pressing elements (202) (302) is the narrowest, if the massage unit (20) is lowered, the state where the affected part is grasped, A massage that takes into account the effect of acupressure that applies more force to the affected area is possible.

  Further, if the massage unit (20) is moved up and down while the affected part is gripped by the two pressing elements (202) and (302), massage that takes into account both gripping and acupressure is possible.

  In addition, by combining the approaching / separating movement of the two pushers (202) and (302) and the vertical movement of the massage unit (20), a massage with a variety of feels that is close to that of a masseuse can be obtained. It is possible.

  In the embodiment, as described above, as shown in FIG. 15, the upper end of the left and right oscillating levers (100) and (100) is fully opened, as shown in FIG. The width center L2 of the presser (302) of the lower second treatment finger (300) is located on the inner side than the width center L1 of the presser (202) of the first treatment finger (200). Furthermore, the width of the upper presser (202) substantially corresponds to the width of the finger row of the second finger to the fifth finger of the finger, and the width of the lower presser (302) is the same as that of the first finger. It is about the same as the width. For this reason, when the masseur squeezes his shoulder, the lower first finger is positioned inward of the width center of the finger row below the second upper finger, and the same itchiness is felt. Is obtained.

  In the embodiment, the free ends between the left and right oscillating levers (100), (100) rise from the state where the distance between them is the narrowest (see FIG. 16) while increasing the distance, and the state where the distance between them is the widest. (See Fig. 15) To descend while narrowing the interval, grab the shoulder and neck from the outside of the shoulder and neck to the inside, and get a massage feeling like a masseur grabbing the shoulder and neck by hand Can do.

  In the practice of the present invention, the massage unit (20) includes body pressure measuring means (92) for measuring the pressing force applied to the user by the pressing element (202) of the first treatment finger (200). Based on the body pressure measured by (92), the operating speed of the first and second treatment fingers (200) and (300) can be adjusted.

  As the body pressure measuring means (92), for example, in the above configuration, the sliding amount of the second link piece (75) relative to the first link piece (73) corresponds to the force applied to the first treatment finger (200). Therefore, as shown in FIG. 6, the slide amount of the second link piece (75) may be measured by a variable resistor (79a) or the like. When the treatment finger (200) (300) hits the shoulder of the user, the first treatment finger (200) receives an upward force, and as a result, the second link piece ( 75) slides up. The sliding amount of the second link piece (75) is detected by the variable resistor (79a), and the pressing force of the first treatment finger (200) can be measured from the detected value.

  For example, when the pressing force of the first treatment finger (200) is large, the first treatment finger (200) is strongly hitting the user, so that the rotation speed of the massage motor (41) is reduced to reduce the first treatment finger ( 200) and the second treatment finger (300) are used to control to slowly grasp and squeeze. On the other hand, when the pressing force of the first treatment finger (200) is small, the treatment finger does not hit the user so much that it is effective to increase the rotation speed of the massage motor (41). .

  Furthermore, comprising a physiological quantity measuring means (96) for measuring a change in physiological quantity during massage of the user, based on the physiological quantity measured by the physiological quantity measuring means (96), the swing lever (100), That is, the operation speed of the first treatment finger (200) and the second treatment finger (300) may be adjusted. Examples of physiological quantities include heart rate, respiratory rate, skin resistance change, and the like, which can be measured by known measuring means.

  Physiological amount is measured. For example, when it is found that the user is relaxed, the swing lever (100) is swung at a high speed, and the first treatment finger (200) and the second treatment finger are swung. The movement of the first treatment finger (200) and the second treatment finger (300) is moved slowly by moving the swing lever (100) slowly when the movement of the (300) is fast and in a tension state. To slow down.

  In addition, a button that allows the user to manually change the rotation speed of the kneading motor (41) or the tapping motor (51) on the operation unit (98) (see FIG. 8) for operating the chair type massage machine. The user may manually change the gripping speed of the treatment fingers (200) and (300) according to his / her preference by using the button.

  In the case of the embodiment, the swing lever (100) (100) repeats approaching (see FIG. 16) and separation (see FIG. 15) every time the kneading shaft (40) rotates during the above operation. In addition, the effect of massaging the user's neck from both sides while rubbing the shoulder from side to side can be achieved.

  The massage unit (20) is housed in the backrest (12), and only the presser (202) of the first treatment finger (200) can press the user, and the vertical motor (26) is Accordingly, the height of the massage unit (20) is adjusted so that the pressing element (202) is positioned on the affected part of the back or waist of the user. The hitting motor (51) is driven to rotate the hitting shaft (50). The rear end of the swing lever (100) is pivotally connected by an eccentric cam (53) (53) and a rod (55) on the hitting shaft (50), so every time the hitting shaft (50) rotates. The swing lever (100) moves back and forth once. This is a massage operation that strikes the back of the user.

  Further, by driving the up / down motor (26) to raise and lower the massage unit (20), it is possible to perform a rolling massage in a state where the presser (202) is strongly pressed against the user.

  Moreover, the first treatment is performed by making the pressing element (302) on the second treatment finger (300) friendly to the user having no corners like the flat roller body (202a) shown in FIG. Of course, the pressing members (202) and (302) of the finger (200) and the second treatment finger (300) may simultaneously hit the back of the user.

  In the above embodiment, the output shaft portions (40a) and (40a) in which the base ends of the swing levers (100) and (100) are rotatably fitted are inclined in opposite directions on the stagnation shaft (40), and The swing lever (100) is swung up and down, back and forth, and left and right by the rotation of the rubbing shaft (40), and the first treatment finger (200) and the second treatment finger are swung by this swing. (300) is moved closer and away.

  However, the output shaft portions (40a) and (40a) may not be eccentric but may be inclined. In this case, the swing lever (100) swings left and right, and when the distance between the swing levers (100) and (100) increases, both the first and second treatment fingers (200) ( 300) increases. When the distance between both swing levers (100) and (100) is reduced, the distance between both treatment fingers (200) and (300) is reduced as shown in FIG.

  Contrary to the above, the output shaft portions (40a) and (40a) may not be inclined but may be eccentric. In this case, when the swing lever (100) moves up and down, back and forth, and swings upward and rearward, as shown in FIG. 13, the interval between the treatment fingers (200) and (300) increases, Further, when swinging forward, as shown in FIG. 14, the interval between the treatment fingers (200) and (300) becomes narrow.

  Further, according to the configuration of the above-described embodiment, the first treatment finger (200) and the second treatment finger (300) are moved toward and away from each other only by moving the massage unit (20) back and forth by the protruding motor (69). To do.

  As shown in FIG. 1, when the massage unit (20) is located rearward, the distance between the first treatment finger (200) and the second treatment finger (300) is widened, and as shown in FIG. In the state where (20) protrudes forward, the interval between the first treatment finger (200) and the second treatment finger (300) is narrowed.

  In addition, by simultaneously driving the massage motor (41) and the projecting motor (69), and also including the vertical drive motor (26), it is possible to perform grip massage with more complex motion. It becomes.
