  An example in which the present invention is applied to a chair-type massage machine (10) will be described.

<Description of structure>
As shown in FIG. 1, the chair (11) of the massage machine (10) includes a seat portion (12) on which a user sits and a backrest portion formed upward from the rear end of the seat portion (12) ( 13) and an armrest portion (14) formed upward on the left and right sides of the seat portion (12). The seat (12), backrest (13), and armrest (14) are each formed by connecting a metal pipe, frame, plate, etc. inside, and the outer periphery is surrounded by a patch or cushion. The

As shown in FIG. 1, the back contact portion (13) is provided with an upper frame (16) and a lower frame (17) at the upper and lower portions, respectively, and left and right of the upper and lower frames (16) and (17). Both end portions are connected by a pair of left and right guide rails (18) and (18) extending parallel to the vertical direction. The upper ends of the guide rails (18) and (18) extend upward beyond the upper frame (16), and the tip of the guide rails (18) and (18) is a head rest that the head of the user hits. (15) is attached. The lower portions of the guide rails (18) and (18) are pivotally supported by a frame forming the seat portion (12). The lower frame (17) is connected to a known reclining mechanism (19), and the backrest portion (13) can swing with respect to the seat portion (12).
The guide rails (18) and (18) have a U-shaped cross section and are arranged so that the grooves face each other, so that the massage unit (30) can be raised and lowered along the guide rails (18) and (18). It is attached.

Inside the backrest portion (13), there is a screw shaft (22) pivotally supported in parallel with the guide rails (18) (18), and a lifting motor (21) that rotates the screw shaft (22). Means (20) are provided. A pulley (23) is provided at the lower end of the screw shaft (22), and is linked to the rotating shaft of the lifting motor (21) via a belt.When the lifting motor (21) is driven, the screw shaft (22) is positive. Rotate or reverse.
The screw shaft (22) is provided with an encoder (24) electrically connected to the control means (70) described later, and the rotation of the screw shaft (22) is transmitted to the control means (70) as a pulse signal. Sent.

Limit switches (33) and (34) are respectively provided above and below one of the guide rails (18) .When the massage unit (30) reaches the upper or lower movement limit, a signal is transmitted to the control means (70 ).
The height position of the massage unit (30) is detected by counting the encoder pulse signal of the screw shaft (22) from the state where the upper or lower limit switch (33) (34) detects the massage unit (30). be able to.

  As shown in FIGS. 1 to 3, the massage unit (30) includes a pair of rollers (31) (31) (31) (31) that fit into the grooves of the guide rails (18) and (18). The pivoted chassis (32) is provided with treatment fingers (40) and (40), squeezing means (50) for operating the treatment fingers (40) and (40), and striking means (60). The chassis (32) has a screw cylinder (35) that is screwed onto the screw shaft (22). As described above, when the screw shaft (22) is rotated, the massage unit (30) is moved up and down by screw thrust. To do.

  The treatment fingers (40) and (40) are provided with a pair of kneading balls (41) and (41) at the upper and lower ends of a plate-like arm (42) bent in a substantially center-shaped shape, and the arms (42) are bent. The part is pivotally supported by a plate-like lever (43). The lever (43) is rotatably supported by the kneading means (50), and a connecting rod (45) is attached to the rear end of the lever (43) via a ball joint (44). (45) is linked to the hitting means (60).

The rubbing means (50) includes a rubbing shaft (52) that pivotally supports the levers (43) and (43) of the treatment fingers (40) and (40), and a rubbing motor that rotates the rubbing shaft (52). (51) Specifically, each lever (43) is pivotally supported by a cam body (52 ′) fixed to the stagnation shaft (52) in an eccentric and symmetrical manner with respect to each other. The power from the stagnation motor (51) is transmitted to the stagnation shaft (52) via the speed reduction mechanism (53).
The massage fingers (40) and (40) are pivotally supported on the kneading shaft (52) in an inclined state, and the levers (43) and (43) are connected to the connecting rods (45) and (45), respectively. Therefore, when the kneading shaft (52) is rotated, the left and right kneading balls (41) and (41) reciprocate while repeating the approach and separation while drawing an elliptical trajectory to perform the kneading operation. (See FIG. 7). In FIG. 7, the amount of change in the front-rear direction of the elliptical trajectory can be greatly increased because the cam body (52 ′) is not only inclined but also eccentric.

As shown in FIGS. 2 and 4, a magnet (55) is attached to the stagnation shaft (52). The magnet (55) and each magnet (55) face the rotational transition path and face the chassis. The rotation of the stagnation shaft (52) is detected by the provided reed switch (56). The reed switch (56) is electrically connected to the control means (70) described later, and transmits the detection of the magnet (55) to the control means (70) as a pulse signal. The reed switch (56) is adjusted in position so that the magnet (55) is detected when the distance between the treatment fingers (40) and (40) is the longest.
The rotation of the stagnation motor (51) is detected by the encoder (54) and transmitted to the control means (70) as a pulse signal.
The treatment is performed by counting the number of encoder pulses of the stagnation motor (51) from the state in which the reed switch (56) detects the magnet (55), that is, the state in which the treatment finger (40) (40) is farthest apart. The distance between the fingers (40) and (40) can be known.
For example, if the reduction ratio of the stagnation motor (51) and the stagnation shaft (52) is set to 40: 1, for example, the reed switch (56) of the stagnation shaft (52) detects the magnet (55), and then the magnet Before detecting (55), the encoder (54) of the stagnation motor (51) detects the rotation of the stagnation motor (51) 40 times. Therefore, the interval between the treatment fingers (40) and (40) is determined by assuming that the position where the reed switch (56) of the kneading shaft (52) detects the magnet (55) is the origin (the state where the treatment finger interval is the most separated). When the kneading motor (51) is rotated 10 times, the treatment finger interval becomes the closest state in the middle and 20 rotations, returns to the origin in 30 rotations and again in the middle and 40 rotations.

The hitting means (60) includes a hitting shaft (62) for supporting the connecting rods (45) and (45) of the treatment fingers (40) and (40) while being shifted from each other by 180 degrees, and the hitting shaft is rotated. A tapping motor (61) is provided. The power from the hitting motor (61) is transmitted to the hitting shaft (62) via the speed reduction mechanism (63).
When the tapping motor (61) is rotated, the treatment fingers (40) and (40) are moved in the vertical direction (including the front and rear direction) via the connecting rods (45) and (45) eccentrically connected to the tapping shaft (62). Move back and forth to perform a hitting action.

As shown in FIG. 2 and FIG. 5, a magnet (65) is attached to the hitting shaft (62), and the magnet (65) and the magnet (65) are arranged on the chassis so as to face the rotation transition path. The rotation of the hitting shaft (62) is detected by the reed switch (66). The reed switch (66) is electrically connected to the control means (70) described later, and transmits the detection of the magnet (65) as a pulse signal to the control means (70). The reed switch (66) is positioned so that the magnet (65) is detected when the amount of protrusion of both treatment fingers (40, 40) forward (to the left in FIG. 1) becomes substantially equal. Is adjusted.
Further, the rotation of the tapping motor (61) is detected by the encoder (64) and transmitted as a pulse signal to the control means (70).
By counting the number of encoder pulses of the tapping motor (61) when the reed switch (66) detects the magnet (65), that is, when the protrusions of the treatment fingers (40) and (40) are almost equal The amount of protrusion of the treatment fingers (40) and (40) can be known.
For example, if the reduction ratio of the tapping motor (61) and tapping shaft (52) is set to 40: 1, for example, the reed switch (66) of the tapping shaft (62) detects the magnet (65), and then the magnet Before detecting (65), the encoder (64) of the tapping motor (61) detects the rotation of the tapping motor (61) 40 times. Therefore, the protruding amount of both treatment fingers (40) and (40) is based on the position where the reed switch (66) of the hitting shaft (62) detects the magnet (65). ), When the tapping motor (61) makes 10 rotations, one of the treatment fingers protrudes forward most, and after 20 rotations, the protrusions of the treatment fingers (40) and (40) become almost equal again, and after 30 rotations the other The treatment finger (40) protrudes the most and returns to the origin after 40 rotations.

The control means (70) for the operation of the massage machine (10) will be described.
FIG. 6 shows the control means (70) mainly composed of the microcomputer (71). The control means (70) is provided at a proper position of the massage machine (10).
In the microcomputer (71), each motor drive circuit (72), (73), (74) that controls the drive of the kneading motor (51), the tapping motor (61) and the lifting motor (21), and the user massage operation An operation unit I / F circuit (76) that receives a signal from the operation unit (79) that selects the recliner control circuit (75) that controls the reclining mechanism (19), and the above-described stagnation motor (51), Encoders (54) (64) (24) that detect rotation of the tapping motor (61) and lift motor (21), reed switch (56) for the kneading shaft (52), reed switch (66) for the tapping shaft (62) Limit switches (33) (34) provided on the upper and lower sides of the guide rail (18) are connected.
In the control means (70), when the user operates the operation unit (79) and selects, for example, massage, hitting or rolling massage, each motor drive circuit (72) (73) ) (74) transmits an operation command to the motors (51) (61) (21), and massage is performed.

  When the user selects massage massage on the operation unit (79), only the massage motor (51) rotates forward, and the treatment finger (40) (40) (actually itching is applied to the affected area of the patient). The balls (41) and (41) (the same applies hereinafter) move closer to and away from each other while drawing a symmetrical elliptical orbit on a substantially horizontal plane. As a result, itching massage is performed on the affected area of the user (see FIG. 7).

  Further, when the user selects hitting massage with the operation unit (79), as shown in FIG. 8, only the hitting motor (61) rotates, and the treatment finger (40) is applied to the affected part of the user. (40) alternately reciprocates in the front-rear direction (including top and bottom), and the affected area of the user is hit and massaged. FIG. 8 shows a state in which the left treatment finger (40) protrudes forward.

  When the user selects the hit and massage massage, a massage in which the massage massage and the massage are combined is applied to the affected area of the user.

<Shiatsu massage of the present invention>
As shown in FIG. 9 and FIG. 10, the driving of the hitting motor (61), which is the hitting means (60), is stopped with one of the treatment fingers (40) protruding most forward. By repeating normal rotation and reverse rotation of the kneading motor (51) which is 50), shiatsu massage is performed on the affected area of the user by the protruding treatment finger (40).

  The protruding amount of the treatment finger (40) includes the encoder (64) for detecting the rotation of the tapping motor (61) described above and the reed switch (66) for detecting the origin position of the treatment finger (40). Is determined. After the origin position is detected by the reed switch (66), when the pulse of the encoder (64) is counted 10 times, one treatment finger (40) protrudes forward most, and the pulse of the encoder (64) from the origin position. Since the other treatment finger (40) protrudes forward when counting 30 times, the control means (70) is based on the output from the reed switch (66) and encoder (64), and the tapping motor (61 ) Is rotated and stopped, so that any of the treatment fingers (40) protrudes most forward.

A specific control flow will be described with reference to the flowchart of FIG.
The user operates the operation unit (79), operates the elevating motor (21) and the kneading motor (51) of the kneading means (50), and places the treatment fingers (40) (40) at a desired height position. And move to the width position (step 1). In this state, the tapping motor (61) is operated (step 2), and in the manner described above, from the reed switch (66) of the tapping shaft (62) and the pulse of the encoder (64) of the tapping motor (61), When it is detected that one of the treatment fingers (40) protrudes most (step 3), the tapping motor (61) is stopped (step 4).

  In the state where one treatment finger (40) protrudes most forward (FIG. 9), by rotating the kneading motor (51) forward and backward (step 5), the protruded treatment finger (40) vibrates little by little to the left and right. And massage with high acupressure effect is given. The forward / reverse rotation of the stagnation motor (51) is, for example, when the reduction ratio of the stagnation motor (51) and the stagnation shaft (52) is 40: 1, the encoder (54) is, for example, 1 to 4 counts, and the stagnation motor (51) The rotation direction of the stagnation motor (51) can be reversed every time the rotation is detected. At this time, it is desirable to reverse the rotation direction of the stagnation motor (51) at intervals of 0.5 to 2 seconds by adjusting the speed of the stagnation motor (51).

  After a predetermined time (for example, 5 to 15 seconds) has elapsed (step 6), the kneading motor (51) is stopped (step 7), and the tapping motor (61) is operated again (step 8). Now, with the other treatment finger (40) protruding most (FIG. 10), the tapping motor (61) is stopped (step 9, step 10).

  In this state, the massage motor (51) is rotated forward and backward (step 11), and the other treatment finger (40) is used to massage the user with high acupressure effect. Forward / reverse rotation of the stagnation motor (51) is performed in the same manner as in step 5 above.

  After a predetermined time (for example, 5 to 15 seconds) has elapsed (step 12), the massage motor (51) is stopped and the shiatsu massage is completed.

Of course, the above flow can be repeated continuously, or can be incorporated into a massage course in combination with massage massage, hitting massage, massage and hitting massage, or the like.
As a method of moving the treatment finger (40) (the massaging ball (41)) to the position where the shiatsu massage is performed, manually operate the elevating motor (21) and the massaging motor (51), and the treatment finger ( 40) may be moved, or a stiffness sensor for measuring the stiffness degree may be provided to automatically move to the location where the stiffness sensor detects the stiffness.
In addition, the control means (70) may store the acupressure position desired by the user so that the user can receive acupressure massage at the desired position.
