  The present invention was invented in view of the above problems, and caused the knee of the user to bend and stretch, and prevented the patient from getting bored by changing the bending and stretching motion. It is an object to provide a massage machine.

In order to solve the above-described problems, the present invention is made up of a seat portion 1 on which a user is seated, a leg rest portion 4 that is rotatably connected to the seat portion 1, and a leg rest portion that rotationally drives the leg rest portion 4. In the massage machine comprising the drive device 12 and the control unit 13 that repeatedly rotates the legrest unit 4 in a predetermined direction from a preset start position by controlling the legrest drive unit 12. the control unit 13, it is assumed that all or rotation angle of a portion of the rotational operation of the second and subsequent rotates the footrest portion 4 so as to be smaller than the rotational angle of the previous, each round of rotation Management of the rotation position at the start position and end point of the operation is performed based on the position management based on the absolute position of the leg rest portion 4 obtained by using the position detection means 14 and the time based on the elapsed time during the rotation operation. This is done by mixed management combined with management.

In the massage machine having the above-described configuration, the user is seated on the seat portion 1 and the legs resting portion 4 holds the both legs so that the leg resting portion 4 performs the above-described series of rotation operations. It is possible to give a leg stretch massage by bending and stretching. In addition, since a lot of stimulation is given by changing the bending and stretching movement, it is possible to prevent the user from getting bored. Further, by performing the above-described mixing management, it is possible to realize a leg stretch massage that is complicated and does not get tired without providing many sensors as the position detection means 14.

  The present invention makes it possible to cause the user's knees to bend and stretch, and to prevent the user from getting bored by changing the bending and stretching motion.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. FIG. 4 shows an example of a massage machine in the embodiment of the present invention. As shown in FIG. 4 (a), the massage machine of this example has a seat part 1 on which a user is seated, a backrest part 2 on which a seated person is seated, and a seated person. The main body is composed of a pair of left and right armrests 3 on which the arm is placed and a leg rest 4 on which a user to be seated places his / her legs. The backrest 2 has a treatment element 8 built therein, and by driving the treatment element 8, various massages such as itching and hitting are performed on the shoulder and back of the user. In addition, a seat airbag 6 is disposed on the seating surface of the seat portion 1 and the inner surface of the armrest portion 3, and a leg airbag 7 is disposed on the inner surface of the leg rest groove 4 having a pair of leg rest grooves. The air bags 6 and 7 are inflated and contracted by the air supplied and exhausted from the air driving device 9 to massage the lower back and legs of the user. In addition, 10 in the figure is an operating device for sending a signal to a control unit 13 described later by operating a button and selecting various massages.

  The leg rest 4 is connected to the front end of the seat 1 so as to be rotatable about a horizontal axis extending in the left-right direction, and drives a motor (not shown) as disclosed in Patent Document 2. The leg rest 4 is moved up and down around the horizontal axis through the leg rest drive device 12 as a source, and its tip is moved up and down to change its posture. Note that the leg mounting unit driving device 12 is not limited to the structure using the motor described above, and may have a structure using air supplied / exhausted from the air supply / exhaust device 9 as a driving source. As shown in FIG. 4B, the leg rest part driving device 12 is controlled by a control unit (MPU) 13 to drive the leg rest part 4 to rotate, and the air driving unit 9 is also controlled. The airbag 13 is controlled by the portion 13 to inflate and contract. Further, in this example, the position detecting means 14 for detecting the rotation position of the leg rest portion 4 is formed using a photo interrupter sensor, and the control section 13 is based on a signal sent from the position detecting means 14. The rotation position and rotation angle of the leg rest part 4 are detected. Note that the position detection means 14 is not limited to the above structure, and other structures may be used as long as the rotation position and the rotation angle of the leg rest portion 4 are detected.

  Accordingly, the user sits on the seat 1 and inserts his lower leg into the pair of leg insertion grooves recessed in the leg rest 4, respectively. By operating a massage selection button, the control unit 13 that has received a signal from the operation device 10 performs the following control to cause the knee to bend and extend.

  Upon receiving the signal from the operating device 10, the control unit 13 first detects the current rotation position of the leg mounting unit 4 based on the signal from the position detection unit 14 and then controls the leg mounting unit driving device 12. Thus, the leg rest part 4 is rotated to the initial start position A set in advance. As shown in FIG. 1, the initial start position A is a position where the surface of the leg mounting portion 4 on which the leg insertion groove is recessed is substantially horizontal and the seat portion 1 and the leg mounting portion 4 are in a straight line. It is. Next, the control unit 13 controls the air driving device 9 to inflate the seat airbag 6 and the leg airbag 7 so that the lower back and legs of the user are securely attached to the seat 1 and the leg rest 4. Hold. Note that the seat airbag 6 and the leg airbag 7 may be inflated in any order or simultaneously.

  Next, the control unit 13 controls the leg mounting unit drive device 12 to rotate the leg mounting unit 4 from the initial start position A by a predetermined initial rotation angle α, which is set in advance. Move to B. Here, the initial rotation angle α is an angle in a direction in which the tip of the leg rest portion 4 is tilted downward (hereinafter, this direction is referred to as a tilt direction). After the leg rest part 4 is moved to the initial rotation position B, the leg rest part 4 is in a direction opposite to the tilting direction and the tip of the leg rest part 4 is raised upward (hereinafter referred to as this The direction is referred to as a standing direction) and moved to a preset second start position C. Here, the second start position C is a position rotated in the tilt direction with respect to the initial start position (that is, the previous start position) A.

  Then, the leg rest part 4 returned to the second start position C is now rotated by the control unit 13 in the tilt direction by the second rotation angle β until the second rotation position D is reached. Moving. The second rotation angle β is larger than the initial rotation angle (that is, the previous rotation angle) α, and the second rotation position D is the first rotation position (that is, the previous rotation angle). Rotation position) A position rotated in a tilting direction from B.

  Due to the above-described series of rotational movements of the leg rest portion 4, the knee of the user performs a bending / extending motion, and a leg stretch massage is performed on the leg portion. In this example, the start positions A and C of the rotation operation in the tilt direction are made different between the first time and the second time, and the rotation angles α and β from the start positions A and C are also made different. Since the rotation positions B and D of the leg rest part 4 at the end of each rotation operation are also set to be different, the first leg stretch massage and the second leg stretch massage are the starting knees. The angle, the knee rotation angle from the start and the knee angle at the end are also different, so the strength and effective part of the leg stretch massage are different between the first time and the second time so that the user does not get bored It is like that.

  After the leg stretch massage is finished, the control unit 13 controls the air driving device 9 to contract the seat airbag 6 and the leg airbag 7 to release the holding of the lower back and leg parts. It is not limited, You may make it cancel | release once in the stage which moved the leg mounting part 4 to the starting position C of the 2nd time.

  In the series of leg stretch massage, the start position and the rotation position of each rotation operation such as the initial start position A, the initial rotation position B, the second start position C, and the second rotation position D are detected by the position detection. Table 1 shows the position management based on the absolute position of the leg rest portion 4 obtained using the means 14, the time management based on the elapsed time during the turning operation, or the position management and the time management. It is performed by mixing management mixed in combination. No. in Table 1 for the above mixed management. In this case, first, the leg rest part 4 is moved to the absolute position of the initial start position A directly designated by the position detecting means 14, and then, for example, 2 from the initial start position A. The leg rest part 4 is moved to the initial rotation position B by rotating the leg rest part 4 in the tilting direction for only one second. Then, in the second rotation operation, the leg rest part 4 is moved to the absolute position of the second start position C directly designated by the position detecting means 14, and then, for example, 3 from the second start position C. The leg rest part 4 is moved in the tilting direction for a second to move to the second rotation position D. By performing such mixing management, it is possible to realize a leg stretch massage that is complicated and does not get tired without providing many sensors as the position detection means 14. Table 1 shows only the case of managing the position of the initial start position A. For example, the leg rest part driving device 12 having a structure that prohibits the pivoting from the initial start position A to the standing direction is provided. If provided, the initial start position A can be managed in time.

  FIG. 2 shows a case where the control unit 13 causes the leg rest part 4 to perform another pattern of rotational movement in the massage machine of this example. The rotation pattern of FIG. 2 is different from the rotation pattern shown in FIG. 1 in that the second start position C matches the initial start position A. That is, in the rotation pattern of FIG. 2, the footrest 4 is rotated in the tilting direction by the initial rotation angle α from the state where the footrest 4 is set at the initial start position A, and then moved to the initial start position A, and then the footrest is mounted. The part 4 is rotated in the standing direction to return to the initial start position A. Then, the first start position A is set as the second start position C, and the leg rest portion 4 is moved to the second rotation position D by rotating the leg rest portion 4 in the tilting direction by the second rotation angle β. It is.

  FIG. 3 shows a case where the control unit 13 causes the leg rest part 4 to perform another rotational movement in the massage machine of this example. 3 is different from the rotation pattern shown in FIG. 1 in that the second start position C coincides with the initial start position A and the second rotation angle β is the first rotation. The difference is that it is set smaller than the moving angle α. That is, in the rotation pattern of FIG. 3, the leg rest part 4 is rotated in the tilting direction by the initial rotation angle α from the state where the leg mounting part 4 is set at the initial start position A and moved to the initial start position A, and then the leg rest is placed. The part 4 is rotated in the standing direction to return to the initial start position A. Then, with this initial start position A as the second start position C, the leg rest 4 is rotated in the tilt direction by a second rotation angle β smaller than the initial rotation angle α. It is moved to the rotational position D. In this case, the second rotation position D is a position rotated to the standing direction side from the first rotation position B.

  Also by the series of rotational movements of the leg rest part 4 shown in FIG. 2 and FIG. 3, the leg stretch massage can be performed by causing the knee of the user to bend and stretch as in the case of FIG. 1. Even in this case, since the rotation angles α and β and the rotation positions B and D are different between the first time and the second time, the leg stretch massage should be changed so that the user does not feel bored. Is possible.

  As described above, only the case of rotating the leg rest part 4 in the tilting direction twice based on FIGS. 1 to 3 has been described. However, the leg rest part 4 is repeatedly rotated three times or more in the tilting direction. Of course, it is also possible to make them. Also in this case, in the second and subsequent predetermined rotation operations, the start position of the rotation operation is different from the start position of the previous rotation operation, or the rotation angle of the rotation operation is The rotation angle of the previous rotation operation is made different, or the start position of the rotation operation is made different from the start position of the previous rotation operation, and the rotation angle of the rotation operation and the By making the rotation angle of the previous rotation operation different, it is possible to make the user feel bored by making the strength of the leg stretch massage different from the effective part. When the leg rest 4 is repeatedly rotated three times or more, all the rotation angles may be different from the previous rotation angle, but only the last rotation operation is a large rotation, for example. It may be set such that only a predetermined number of rotation angles are different from the previous rotation angle, such as by an angle.

It is explanatory drawing which shows typically rotation of the leg mounting part at the time of leg stretch massage of the massage machine of an example in embodiment of this invention. It is explanatory drawing which shows typically rotation of the leg mounting part at the time of the leg stretch massage of the other pattern of a massage machine same as the above. It is explanatory drawing which shows typically rotation of the leg mounting part at the time of the leg stretch massage of another pattern of a massage machine same as the above.
