2. Description of the Related Art FIG. 10 and FIG. 11 show a conventional chair-shaped massaging machine 1. FIG. 10 is a rear view showing the overall configuration of the conventional massage machine 1, and FIG. 11 is a front view of a part of an operating device (hereinafter, remote controller) 16 provided in the massage machine 1. Hereinafter, the overall configuration of the massaging machine 1 of the first conventional example will be described with reference to FIGS. 10 and 11. Racks 4a and 4b are fixed to both sides in the width direction inside the backrest portion 3 of the chair 2 which is a component of the massaging machine 1, and are provided in a drive mechanism 5 having a massaging element (not shown) for massaging. A pair of pinions 6a and 6b are engaged with the racks 4a and 4b. A pulse generator (not shown) is used as an example for raising and lowering the drive mechanism 5 provided in the drive mechanism 5.
The rotation of a DC brushless motor (hereinafter, referred to as a motor) 7 including a motor is transmitted to a rotary shaft 9 via a motion conversion mechanism 8 using a gear or the like. By rotating the rotary shaft 9 in one of the two directions by the motor 7, the pinion 6a,
6b rotates and pinions 6a and 6b and racks 4a and 4b
The drive mechanism 5 is moved up and down by the backrest portion 3 of the chair 2 by the engagement with the. Further, in order to define the upper limit position and the lower limit position when the drive mechanism 5 moves up and down, the racks 4a, 4
A lower limit switch 10 and an upper limit switch 11 are provided near the upper end and the lower end of b.

In this massaging machine 1, when massaging the shoulder part of a person to be treated with a massager, when determining the high and low positions,
Based on the lower limit switch 10, the motor 7
The number of pulses from the pulse generator is counted, and when the motor 7 rotates by a predetermined number of pulses, it is set to the middle position. Further, the number of pulses from the pulse generator of the motor 7 is counted on the basis of the middle position, and the high position is set when the motor 7 rotates by a predetermined number of pulses.

The remote controller 16 shown in FIG. 11 has a low position switch 17, a middle position switch 18, and a high position switch for adjusting the high and low positions of the massage position by means of a roller provided in the drive mechanism 5. A light emitting diode (hereinafter, LED) 2 is provided in the vicinity of each switch 17 to 19 and lights up when the switch 17 to 19 is pressed.
0, 21, and 22 are arranged respectively. Here, regarding the massager of the massaging machine 1, the distance between the high position and the middle position and the distance between the middle position and the low position are 30 mm, respectively, as an example.
Stipulated. Therefore, the predetermined pulse number is set to the pulse number corresponding to the interval of 30 mm.

When the low position switch 17 is operated using the remote controller 16, the motor 7 is driven until the drive mechanism 5 reaches the lower limit switch 11. When the middle position switch 18 or the high position switch 19 is operated, the motor 7 is rotated by the predetermined number of pulses with reference to the lower limit switch 11, and the drive mechanism 5 reaches the middle position or the high position.

Therefore, in the conventional massaging machine 1, the massaging positions of the shoulders of the person to be massaged by the massagers are predetermined at three discrete positions, as an example, so that they are intermediate positions. There is a problem in that it is not possible to finely adjust the setting, and it is difficult to massage the desired part of the patient, and the usability is low. In addition, the pulse generator is required to control the movement distance when the drive mechanism 5 is driven up and down, and there is a problem that the configuration becomes complicated and the size becomes large.

FIG. 12 is a perspective view showing the structure of another conventional massaging machine. In this conventional example, referring to FIGS. 10 and 11, except that a rotary encoder described below is used to control the moving distance of the drive mechanism 5 shown in FIG. 10, instead of the pulse generator of the conventional example. This is the same as the configuration of the massage machine 1 described above. As shown in FIG. 12, a gear 12 is fixed to the rotary shaft 9, and a disc-shaped gear 13 that meshes with the gear 12 to rotate is provided. The gear 13 has a plurality of long grooves 14 along the circumferential direction. Are formed. Further, a sensor 15 such as a photo interrupter for detecting the long groove 14 is arranged near the gear 13. The sensor 15 detects the long groove 14 of the gear 13 that rotates with the rotation of the rotating shaft 9. Each long groove 1 is processed by processing a detection signal from the sensor 15 provided in the rotary encoder by a microcomputer (not shown).
4, the detection order and the detection frequency per unit time are detected,
It becomes possible to detect the rotation direction and the rotation speed of the rotating shaft 9. Therefore, also with this configuration, the drive mechanism 5
It is possible to control the moving distance of the.

In this conventional example, the gears 12 and 13 and the sensor 15 are required to control the moving distance of the drive mechanism 5, the number of parts increases, the structure becomes complicated, and the wiring becomes complicated. There is a problem.

FIG. 13 is a front view of a remote controller of another conventional massaging machine. This conventional example has the same configuration as that of the massaging machine 1 described with reference to FIGS. 10 and 11, except that the configuration described below is used instead of the remote controller shown in FIG. 11. As shown in FIG. 13, the remote controller 2
3 is provided with a slide switch 24. In the vicinity of the slide switch 24, a height scale 25 that indicates aggregating positions of several steps by numbers is provided. In this conventional example, the slide switch 24 is moved so that the instruction display 26 indicated by an arrow or the like provided on the slide switch 24 is moved to the height scale 25.
By matching with a predetermined number of, the drive mechanism 5 is moved to the massage position corresponding to the number. The structure described with reference to FIGS. 10 to 12 is used for the movement control of the drive mechanism 5.

In this conventional example, the abrading position can be adjusted in several steps such as 6 steps, and finer adjustment can be made than in the case of FIG. On the other hand, since the massage position is displayed in the numerical notation, it is difficult to determine the correspondence between each number on the height scale 25 and the vertical direction of the actual massage position.
It is difficult to determine the individual correspondence between each number and the actual massage position, and the operability of the remote controller is low.

[0011]

Indicator light 83,
84 are arranged.

A structural example of the drive mechanism 35 of the massaging machine 31 will be described below with reference to FIG. In the drive mechanism 35,
A rotating shaft 39 for raising and lowering, a rotating shaft 46 for kneading operation, and a rotating shaft 47 for beating are rotatably mounted between a pair of frames 44 and 45 which are parallel to each other. The rotary shaft 39 is rotationally driven by the rotation of the motor 37 via the motion conversion mechanism 38, and the drive mechanism 35 is vertically driven. The rotation shaft 46 is driven by a reciprocal angular displacement as will be described later by the rotation of the motor 41 via the motion converting mechanism 42, and the rotation of the rotary shaft 46 is converted by the motion converting mechanism 93 into the swinging motion of the masses 40a, 40b. Rubbers 40a, 4
0b performs a kneading operation on the patient. The rotary shaft 47 is rotationally driven by the rotation of the motor 49 via the motion conversion mechanism 48, and performs a striking motion.

The rotating shaft 46 is formed in a hexagonal columnar shape between the frames 44 and 45, and a pair of cylindrical cam members 50 and 51 are respectively provided in the middle portions of the rotating shaft 46 so as to be offset with respect to the rotating shaft 46. It is installed with care. Cam member 5
Rubbers 40a and 40b are attached to the front ends of 0 and 51, respectively, via arms 52 and 53 that are bent in a crank shape. One ends of rods 54 and 55 are fixed to the rear ends of the cam members 50 and 51 opposite to the arms 52 and 53, respectively.
As an example, bearing bands 56 and 57 made of synthetic resin are fixed to the other ends of 4 and 55, respectively. The bearing bands 56 and 57 are swingable on the rotary shaft 47 as will be described later, and are mounted at positions eccentric to the axis of the rotary shaft 47. Therefore, when the rotary shaft 47 rotates, the bearing bands 56 and 57 revolve around the rotary shaft 47.

As a result, the rods 54 and 55 are periodically pulled by the bearing bands 56 and 57. The movements of the rods 54, 55 are converted into reciprocating angular displacement movements of the cam members 50, 51 because the cam members 50, 51 are rotatably connected to the rotary shaft 46. As a result, the massaging elements 40a and 40b move up and down, and a tapping operation is performed. The motion converting mechanism 93 is configured to include the cam members 50 and 51, the arms 52 and 53, and the rods 54 and 55.

The details of the structure relating to the cam members 50 and 51 will be described below. In the hexagonal columnar portion of the rotary shaft 46, sliders 58 and 59 each having a hexagonal cylindrical shape and having a substantially cylindrical outer shape corresponding to the hexagonal columnar shape of the rotary shaft 46 are respectively provided on the rotary shaft 46. The hexagonal column-shaped portion is eccentrically mounted so as to be movable in the axial direction. The sliders 58 and 59 are coaxially connected to the cam members 50 and 51 via bearings (not shown).
Therefore, the cam members 50 and 51 have an axis line eccentric to the axis line of the rotary shaft 46, and the axis line of the rotary shaft 46 passes through the eccentric position. As a result, the cam members 50 and 51 perform an elliptical motion in a direction perpendicular to the axis of the rotary shaft 46 in accordance with the degree of eccentricity of the cam members 50 and 51 due to the rotation of the rotary shaft 46.

The bearing bands 56, 57 to which the other ends of the rods 54, 55 are fixed are, for example, in a direction perpendicular to the axis of the rotary shaft 47 by a structure similar to the structure related to the cam members 50, 51. It is configured to perform an elliptic motion with respect to. Engaging projections 85, 86 are formed on the circumferences of the bearing bands 56, 57, and the engaging projections 8
5, 86, the other ends of the rods 54, 55 are the rotating shafts 4
A pin (not shown) in a direction perpendicular to the axis of the shaft 7 is angularly mounted around the pin.

The electrical construction of the massaging machine 31 of this embodiment will be described below with reference to FIG. The massaging machine 31 includes an operation remote controller 64 for setting various massaging operations, and the remote controller 64 is connected to the microcomputer 87. The microcomputer 87 includes motors 37, 4
1, 49 are connected. The microcomputer 87 includes a timer 88, a counter 89, and a counter 89.
Limit value storage unit 90 for storing count limit values described later
And are provided. The counter 89 has a limit value storage section 90 based on the timing signal generated from the timer 88.
Within the range of the limit value stored in, the counting operation as described later is performed.

Hereinafter, the lifting operation of the drive mechanism 35 of the massaging machine 31 will be described with reference to FIGS. In the massaging machine 31 of the present embodiment, as an example, the raising / lowering operation of the drive mechanism 35 in the shoulder position adjusting operation when the shoulder of the user is massaged will be described. As a matter of course, the same operation can be performed for the raising / lowering operation of the drive mechanism 35 in the massage operation of the other parts.

When the massaging machine 31 is used to perform the massaging operation on the shoulder, the remote control 64 is used to set a desired massaging operation such as a kneading operation or a tapping operation. The motor 41 is driven when the kneading operation is selected, and the motor 49 is driven when the hitting operation is selected. Next, the shoulder button 73 is pressed.
At this time, the microcomputer 87 stores position data corresponding to the standard shoulder position P0 shown in FIG. 9, and the drive mechanism 35 is moved to the standard shoulder position P0.
The massage operation corresponding to the operation of each of the buttons 66 to 71 is started. At this time, in the microcomputer 87, for example, interrupt processing is performed every 1 ms as shown in FIG. 8C based on the timing signal generated from the timer 88, and the alignment of FIG. 7 is performed for each interrupt. The program will be started. At this time, the microcomputer 8
The count value of the counter 89 of 7 is set to zero as an example.

In step a1 of the process of FIG. 7, it is detected whether or not the raising switch portion 81 of the positioning switch 75 is operated, and if it is not operated, the raising / lowering drive motor 37 is rotated in the raising direction in step a2. Is stopped. At step a3, the lowering switch portion 82 of the alignment switch 75
The presence or absence of the operation is detected, and if the operation is not performed, the rotation of the lifting drive motor 37 in the descending direction is stopped in step a4. After that, the process returns to step a1.

When the operation of each of the switch parts 81 and 82 is detected in step a1 or step a3, the process proceeds to steps a9 and a5, respectively. In the following description, it is assumed that the lowering switch unit 82 is operated first. At this time, the determination at step a1 is negative, the determination at step a3 is affirmative, and the rotation of the motor 37 in the descending direction is started at step a5. In step a6, when the timing signal every 1 ms is obtained from the timer 88, the count value i of the counter 89 is down-counted. In this case, the initial count value 0 is down-counted by 1 and the count value i is-. Becomes 1. Next, step a
At 7, it is determined whether the count value i has reached the limit value of -3000 as an example stored in the limit value storage unit 90. If it has arrived, the rotation of the motor 37 in the direction corresponding to the descending direction is stopped in step a8, and the process returns to the program for controlling the operation of the entire massaging machine 31.

If the determination in step a7 is negative, the process returns to the program for controlling the operation of the entire massaging machine 31 from the process in FIG. 7, and the process starts again from step a1 at the next interrupt timing. In this way, as shown in FIG. 8B, the down switch unit 82 is operated, for example, for a period of four counts of the timing signal, and at that time,
When the operation of the lowering switch unit 82 is completed, the microcomputer 87 does not detect the operation of the lowering switch unit 82 at the next interrupt timing, the determination in step a3 becomes negative, and the count value i of the counter 87 is −2996. Then, at step a4, rotation of the motor 37 in the direction corresponding to the descending direction is stopped, and the process returns to step a1.

Here, if the operation of the lowering switch section 82 is continued and the determination in step a7 is affirmative, the microcomputer 87 determines that the drive mechanism 35 has reached the lower limit position of the shoulder position, and then step a8. Then, the rotation of the motor 37 in the direction corresponding to the descending direction is stopped. The microcomputer 87 drives the drive mechanism 35 when the count value i of the counter 89 reaches -3000 or when the lower limit switch 63 shown in FIG. 1 operates.
Is determined to have reached the lower limit position of the shoulder position, the motor 37
The rotation in the direction corresponding to the descending direction of is stopped.

Following the operation of the lowering switch section 82,
When the raising switch unit 81 is operated as shown in FIG. 8A, the microcomputer 87 operates the raising switch unit 8
This operation is detected at the next interrupt timing after the operation of 1. At this time, the determination in step a1 becomes affirmative, and the rotation of the motor 37 in the direction corresponding to the rising direction is started in step a9. In step a10, when the timing signal every 1 ms is obtained from the timer 88, the count value i of the counter 89 is counted up. In this case, the count value −2996 is incremented by 1, and the count value i becomes −2997. Next, in step a11, the count value i is the limit value storage unit 90.
For example, it is determined whether the limit value of 3000 has been reached. If reached, step a12
The rotation of the motor 37 in the direction corresponding to the ascending direction is stopped, and the process returns to the program for controlling the operation of the entire massaging machine 31.

If the determination at step a11 is negative, the process shown in FIG.
The process returns to the program for controlling the operation of the massaging machine 31 as a whole, and the process starts again from step a1 at the next interrupt timing. In this way, as shown in FIG. 8A, the rising switch unit 81 is operated for a period of 6 counts of the timing signal as an example, and when the operation of the rising switch unit 81 is finished at that point, the micro The computer 87 does not detect the operation of the rising switch unit 81 at the next interrupt timing, and the determination at step a1 becomes negative. At this time, in step a2, the rotation of the motor 37 in the direction corresponding to the rising direction is stopped. If the lowering switch unit 82 has not been operated, the determination in step a3 is also negative, the rotation of the motor 37 in the direction corresponding to the lowering direction is stopped in step a4, and the process returns to step a1.

Here, if the operation of the raising switch 81 is continued and the determination in step a11 is affirmative, the microcomputer 87 determines that the drive mechanism 35 has reached the upper limit position of the shoulder position, and proceeds to step a12. And the motor 3
The rotation in the direction corresponding to the descending direction of 7 is stopped. The microcomputer 87 operates the drive mechanism 3 when the count value i of the counter 89 reaches 3000 or when the upper limit switch 62 shown in FIG. 1 operates.
5 has reached the upper limit position of the shoulder position, the motor 3
The rotation in the direction corresponding to the ascending direction of 7 is stopped.

When the desired massage position on the shoulder of the patient is set in this manner, the massage machine 31 performs the massage operation as outlined below at this massage position. The microcomputer 50 rotates the motor 41 to rotate the rotation shaft 4
6 is rotated so that the sliders 58 and 59 mounted on the cam members 50 and 51 move the eccentric position to the rotary shaft 46.
Is configured to pass through, the cam members 50 and 51 perform a reciprocal angular displacement motion in a part of the elliptical motion in a direction perpendicular to the axis of the rotating shaft 46 in accordance with the degree of eccentricity. . At this time, the opposite sides of the massaging members 40a, 40b connected to the cam members 50, 51 are connected to the rotary shaft 47 via the rods 54, 55 and the bearing bands 56, 57. As described above, this connection is configured such that the rods 54 and 55 can swing with respect to the rotating shaft 47 and the distance from the rotating shaft 47 is fixed. Therefore, the rotational movement of the cam members 50 and 51 is centered on the connecting position of the cam members 50 and 51 with the rods 54 and 55, and the distance from the connecting position to the rotating shaft 46 and the mass of the masses 40a and 40b from the connecting position. A reciprocating angular displacement movement of the massaging elements 40a, 40b having an amplitude amplified in proportion to the ratio to the distance. As a result, the massagers 40a and 40b can be installed in the chair 32.
The massaging operation is performed by rubbing the shoulder portion of a person leaning on the backrest portion 33 of the person.

Further, in order to perform the hitting operation, the rotary shaft 47 is rotationally driven by the microcomputer 87. When the rotary shaft 47 rotates, the bearing bands 56 and 57 revolve around the rotary shaft 47. As a result, the rods 54 and 55 are periodically pulled by the bearing bands 56 and 57. The movements of the rods 54, 55 are converted into reciprocating angular displacement movements of the cam members 50, 51 because the cam members 50, 51 are rotatably connected to the rotary shaft 46.

Therefore, in order to control the moving amount of the drive mechanism 35, it is possible to eliminate the need to use the pulse generator or the rotary encoder as used in the related art, and it is possible to realize the effect of simplifying the configuration.

Further, the massaging machine 31 of the present embodiment is similar to that shown in FIG.
In steps a7 and a11, the predetermined movement range of the drive position of the drive mechanism 35 to the shoulder portion is regulated,
Even if the raising switch 81 or the lowering switch 82 of the alignment switch 75 is operated excessively, it is possible to prevent the drive mechanism 35 from moving beyond the predetermined upper end and lower end of the moving path. The operability of the massaging machine 31 is improved. Further, the movement amount of the drive mechanism 35 is regulated by the upper limit regulation pieces 60 at the upper end portion and the lower end portion of the rack 34 that define the movement path of the drive mechanism 35 in the chair 32, respectively.
And the lower limit regulating piece 61 are arranged so that the upper limit regulating piece 62 and the lower limit regulating piece 61 are respectively detected by the upper limit limiting switch 62 and the lower limit limiting switch 63 arranged at the upper end portion and the lower end portion of the drive mechanism 35. Also by
It is mechanically guaranteed. Therefore, if the microcomputer 87 malfunctions, the steps a7, a1
Even if the soft movement range restriction in 2 does not work, the drive mechanism 35 is prevented from moving beyond the upper end portion and the lower end portion of the movement path, and the operability of the massaging machine 31 is improved.

The structure described in the above embodiment shows one embodiment of the present invention and does not limit the scope of the present invention. The present invention includes a wide range of modifications without departing from the spirit of the present invention.
