Embodiments of the present invention will be described below with reference to the drawings. The present invention is not limited by this.

FIG. 1 is a structural explanatory view of the inside of a chair type massage machine M viewed from the side. In FIG. 1, the rotation of a vertical motor 9 located at the lowest position inside the backrest of the chair in the massage machine M is reduced by a pulley and a belt and transmitted to a screw shaft (main shaft) 12. The elevating unit 10 and the screw shaft 12 are fixed to the elevating unit 10 and are connected by a screw member 6. Lifting unit 1
0 moves up and down along the screw shaft 12 via the female screw member 6 due to the forward and reverse rotation of the screw shaft 12.

The lifting unit 10 reaches the upper limit switch 13 as it continues to ascend, and reaches the lower limit switch 14 as it continues to descend. The vertical position can be recognized by detecting a pulse from a vertical movement detecting magnet reed switch (not shown). Each time the screw shaft 12 makes one rotation, a magnet (not shown) attached to the screw shaft 12 passes in front of the reed switch, and a pulse is generated.

The rotation of the arm motor 8 is transmitted to the worm shaft 19 inside the lifting unit 10. The arm 16 and the worm wheel 11 are screwed to a horizontal rotation shaft 21 fixed to the lifting unit 10. The worm wheel 11 has a fan shape, and rotation from the worm shaft 19 is transmitted. As shown in FIG. 2, a pair of left and right massage treatment elements (fir balls) 15, 15 are attached to the upper end of the arm 16 via a horizontal attachment shaft 20.

When the worm wheel 11 rotates in one direction, the treatment elements 15 rotate obliquely upward (in a direction away from the massaged person) about the rotating shaft 21. When the worm wheel 11 rotates in the other direction, the treatment element 15
15 rotates obliquely downward (in a direction approaching the massaged person) around the rotation shaft 21. The range of such movement is limited by the contact of the worm wheel 11 with the upper limit switch 17 and the lower limit switch 18. The angle of movement, that is, the angle of the treatment elements 15 with respect to the massage site can be determined by obtaining a rotation pulse of the worm shaft 19 by an angle sensor (not shown) as angle detection means.

The arm 16 is provided with a load sensor 1 as a pressing force detecting means. This load sensor 1
Is for detecting the pressing force (load) of the treatment elements 15 to the massage site. That is, the load applied to the arm 16 is detected and converted into an electric signal. The massage machine M further includes a control unit as shown in FIG. In FIG. 5, reference numeral 3 denotes a body shape detection / calculation device, 4 denotes a memory device, 5 denotes a calculation device, 7 denotes a motor control circuit,
All of these constitute a control unit.

Next, a specific description will be given based on the flowcharts shown in FIGS. When the power switch is turned on, the up / down motor 9 starts rotating. Then, the elevating unit 10 is lowered until the lower limit switch 14 as a home position when the body shape is detected is turned on (S1). When the home position is detected, the vertical motor 9 is stopped, and the arm motor 8 is controlled so that the load on the arm 16 becomes a constant value. When the load reaches a certain value, the vertical motor 9 is turned on, and the lifting unit 10 starts to be lifted (S2).

The data from the angle sensor is sampled at regular time intervals while controlling the arm motor 8 so that the load always becomes constant. The obtained angle data is stored in the memory device 4 (S3). When the upper limit switch 13 is turned on, the vertical motor 9 is stopped. Thus, the body shape detection ends (S4). FIG. 6 shows the obtained angle data.

From the extreme points A, B, C, D, and E in FIG. 6, it is detected that each is a hip, a waist, a shoulder, a neck, and a head (S5). Then, the value of the time axis (horizontal axis) is stored in the memory device 4 (S6). Based on the stored angle data and the part data from the head part to the head part, the set load of each part at the time of load control is calculated (S7), and this is stored in the memory device 4 again (S8). The data at the time of the set load is shown in FIG. In FIG. 7, the standard load is 15 kgf.
Is set to Also, the waist B is slightly stronger at 20 kgf.
In addition, the neck D is set to a slightly weaker 10 kgf.

Next, a safe angle area as shown in FIG. 8 is determined from the obtained data of FIG. That is, as shown in FIG. 8, the operation angle regions of the treatment elements 15 at the neck D and the head E are narrower than other regions. Specifically, the neck D is downward (in a direction approaching the massaged person).
5 ° to the top 15 (in the direction away from the massaged person)
°, the head E is 5 ° downward and 10 ° upward. On the other hand, for the hip part A and the waist part B, each is 15 ° both up and down, and for the shoulder part C, each 10 ° both up and down
It is. Thus, the treatment element 15.1 at the neck D and the head E
By making the operation angle region 5 narrower than the other portions, the treatment elements 15 at the neck D and the head E are prevented from protruding significantly toward the massaged person.

The pressing force control will be described with reference to the flowchart of FIG. The angle of the arm 16 is detected, and it is determined whether the angle is within a predetermined safe angle area. Then, if within the safe angle range, the pressing force control is performed, and the forward / reverse rotation of the arm motor 8 is performed. On the other hand, if it is out of the safe angle area, the arm motor 8 is stopped, and the treatment element 1
5 and 15 are controlled so as not to protrude significantly toward the massaged person.

In this chair type massage machine M, a comfortable massage according to the body shape can be performed by detecting the body shape of the massaged person by controlling the pressing force of the treatment elements 15 and detecting the angle. . In addition, treatment child 15
By preventing the 15 from going out too much, a safe massage can be given without giving a sudden shock to the massaged person.

[0023]

The chair-type massage machine of the present invention is constructed as described above, so that a comfortable massage can be performed according to the body shape of the person to be massaged. In addition, by preventing the treatment element from excessively protruding to any of the massage parts, a safe massage can be performed without giving a sudden shock to the massaged person.
