Here, the Ashinodai 2 a U shape of the insertion groove 20 of the right and left legs or feet of the user A are respectively inserted are provided side by side to span in the longitudinal direction. Further, as shown in FIG. 1B, the foot placement portion 3 is provided with side pressing means 17 for pressing each foot placed in each insertion groove 20a from the side. The side pressing means 17 is disposed on the outer side surface of each insertion groove portion 20a and is disposed on the inner side surface of each insertion groove portion 20a. It is comprised with the foot inner side pressing means 19 which presses each leg | foot from the inner side. The foot outer side pressing means 18 includes separate front outside foot pressing portions 18a and rear outside foot pressing portions 18b which are disposed corresponding to the front and rear of the foot. In addition, the foot inner side pressing means 19 is configured to include separate in-foot front pressing portions 19a and back in-foot pressing portions 19b arranged corresponding to the front and back of the foot. The front outside pressing part 18a and the front inward pressing part 19a are arranged opposite to each other via the insertion groove 20a, and the rear outside pressing part 18b and the rear inward pressing part 19b are connected to the insertion groove 20a. Via the left and right. Specifically, each of the front pressing portions 18a and 19a can press a portion near the toe of the foot from the side, and each of the rear pressing portions 18b and 19b can press a portion near the heel of the foot from the side. . Each of the pressing portions 18 and 19 is constituted by an airbag 24. Each air bag 24 can be inflated and contracted by air supply / exhaust, and each air bag 24 can selectively supply and exhaust air to the air supply line 22 from the air pump 21 as shown in FIG. An electromagnetic valve 23 is disposed, and the drive control of the air pump 21 and each of the foot electromagnetic valves 23 is performed by the control unit 11 as shown in FIG. Note that the air bag 24 constituting the side pressing means 17 is an example, and the side pressing means 17 can also be constituted by a fluid bag that expands and contracts by a fluid supply / discharge operation of a fluid constituted by a gas other than liquid or air. .

  In the massage machine 1 of the present example having the above configuration, the control unit 11 causes the side pressing means 17 to perform the following drive control, thereby causing the foot to perform a twisting motion to the left and right to stretch the foot. Has been made possible. The control unit 11 is provided with an automatic course in which a predetermined stretching operation is programmed in advance, and the user sitting on the seat unit 5 selects and starts the automatic course by operating the operation unit 12. A predetermined drive for causing the foot to perform a right / left twisting motion is performed. In the figure, the right foot will be described as an example.

  FIG. 4 shows an example of causing the foot to perform a left / right twisting exercise under the control of the control unit 11. That is, the foot 24 is placed on the footrest 3 in a state where the airbags 24 that are the side pressing means 17 are not inflated. According to the control unit 11, in this state, first, the front and rear central portions (toes) By supplying air to the outer front side pressing portion 18a and the in-foot rear side pressing portion 19b, which are the side pressing means 17 that are diagonally positioned with respect to the boundary between the heel and the heel, and inflating them. The outer front side pressing part 18a and the inner rear side pressing part 19b press the outer part in the vicinity of the toe of the foot and the inner part in the vicinity of the heel so that the part in the vicinity of the toe of the foot is inward and the vicinity of the heel of the foot. Move the foot outwards to cause the feet to twist left and right (inward). Next, it is the side pressing means 17 that has not been inflated at the tip, and the foot front side pressing portion 19a and the back of the foot that are diagonally positioned with respect to the front-rear center portion (the portion between the toes and the heel) as a boundary. By supplying air to the side pressing part 18b and inflating it, the in-foot front pressing part 19a and the out-of-foot rear pressing part 18b press the inner part in the vicinity of the toe of the foot and the outer part in the vicinity of the heel, This causes the foot to perform a twisting motion to the left and right (outside) by moving the vicinity of the toe of the foot outward and the vicinity of the heel of the foot inward. Thereafter, by repeatedly performing this operation, it is possible to perform a right and left twisting motion in which the front and rear portions of the foot are alternately swung in the left and right directions around the center. Of course, at the end of the treatment, each airbag 24 as the side pressing means 17 is contracted by the control of the control unit 11 so that the foot can be easily removed from the insertion groove portion 20a of the footrest portion 3.

  That is, in this example, the control unit presses the foot with one side pressing means 17 (for example, the foot outer side pressing means 18), and at the same time, the other side pressing means 17 (for example, the foot inner side pressing means 19) The foot deviated back and forth from the pressing point of one side pressing means 17 is pressed, and both the front and rear parts of the foot are pressed by the respective side pressing means 17 (the foot outer side pressing means 18 and the foot inner side pressing means 19). By performing control so as to move in the opposite left and right directions that are the respective pressing directions, a twisting motion to the left and right is performed on the foot. The leg muscles are stretched with the twisting motion of the foot, that is, a stretching effect can be imparted to the leg muscles that stretch with the twisting motion of the foot to the left and right.

  FIG. 5 shows another example in which the feet are twisted by the control of the control unit 11. That is, the foot 24 is placed on the footrest portion 3 in a state where the airbags 24 as the side pressing means 17 are not inflated. According to the control portion 11, in this state, first, the foot rear side pressing portion 19b is first introduced. And inflating by supplying air to the rear foot pressing portion 18b and the rear foot pressing portion 19b and the rear foot pressing portion 18b, the inner portion and the outer portion near the heel of the foot. By pressing, the region near the heel of the foot is clamped and held from the left and right. Next, in the state where the vicinity of the heel is held, air is alternately supplied and exhausted to the front outside press part 18a and the front front press part 19a to be expanded and contracted, and the inside and outside in the vicinity of the toe of the foot are alternately By pressing, the toe vicinity of the foot is alternately moved in the pressing direction of the outer front side pressing portion 18a and the inner front side pressing portion 19a, that is, the vicinity of the toe of the foot is alternately shifted left and right around the heel portion of the foot. Twist the foot to the left and right to swing it. Of course, the foot is pressed from both the left and right sides by the front outside pressing part 18a and the front inside pressing part 19a to hold and hold the vicinity of the toe of the foot, which is the pressing point, and then the rear back pressing Even by pressing the foot alternately between the portion 19b and the rear foot pressing portion 18b, it is possible to swing the foot heel in the left and right directions so that the left and right sides of the foot are twisted.

  In other words, in this example, the clamping unit holds and holds a part of the foot with the pair of side pressing means 17 (the foot outer side pressing means 18 and the foot inner side pressing means 19). The foot portion of the foot is not moved substantially, and then the foot at a position shifted back and forth from the pinching point is pressed by one side pressing means 17 (for example, the foot outer side pressing means 18). By controlling the point foot part to move in the pressing direction, a twisting motion to the left and right is performed on the foot. This also provides a stretch effect to the leg muscles that stretch with the twisting motion of the foot from side to side.

  In this way, the left and right side pressing means 17 (18, 19) disposed on the left and right side surfaces of the insertion groove portion 20 of the footrest 3 are actuated, and the foot portion pressed by at least one side pressing means 17 is operated. By moving the foot in the pressing direction, it is possible to cause the foot to perform a twisting motion to the left and right by moving a certain position on the front and back of the foot relatively to the left and right relative to other positions. Therefore, it is possible to stretch the muscles that stretch with the twisting motion to the left and right. The effect of stretching the foot by twisting the left and right of the foot is effective for preventing the fall of the user and for functional training of the user who suffers from hemiplegia of the foot due to stroke etc. Is. More specifically, according to the control unit 11, if the foot is positioned on the footrest unit 3, the foot can be quickly and automatically twisted to the left and right. There is also an advantage that comfortable massage treatment can be performed with good usability without imposing a complicated operation of fixing a foot with a fixing belt. Of course, by pressing the local part on the side of the foot directly with the side pressing means 17, it is possible to give a massage-like stimulus to the local part of the foot to be pressed while twisting the foot to the left and right. .

  More specifically, in the operation of selectively repeatedly inflating and contracting the predetermined airbag 24 of the previous side pressing means 17, switching of the airbag 24 to be inflated and contracted while suppressing the amount of air supplied to the airbag 24. Performing at a relatively high speed (switching each airbag 24 to be inflated and contracted rhythmically without providing time for maintaining the maximum inflated state of the airbag 24), and switching the airbag 24 to be inflated at least about 10 times By doing so, the ankle joint fluid comes out at the ankle joint, and the ankle joint loosening effect can be obtained. Further, in the operation of selectively repeatedly inflating and contracting the predetermined airbag 24 of the previous side pressing means 17, the switching of the airbag 24 to be inflated and contracted relatively frequently is performed with a large amount of air supplied to the airbag 24. (Specifically, the time for maintaining the maximum inflated state of the airbag 24 is provided for about 12 seconds), the Golgi healthy organ works and the leg muscles that stretch with the twist of the leg become loose. It can be further extended, that is, an effective stretch effect can be obtained.

  The above-described left / right twisting movement of the foot by the side pressing means 17 can be performed by means other than the fluid bag such as the airbag 24. For example, FIG. 6 shows an example in which the side pressing means 17 is composed of a pressing body 25 that protrudes and retracts by driving a motor. The pressing body 25 is formed of a relatively soft material such as urethane and is inserted so as to protrude from the side surface of the insertion groove portion 20a toward the left and right center portion of the insertion groove portion 20a or to be immersed in the side surface of the insertion groove portion 20a. It is arrange | positioned at the side surface of the groove part 20a. Specifically, the pressing body 25 is provided with a pressing body driving means 26 for driving the pressing body 25, and the pressing body driving means 26 of this example uses a motor (not shown) with a nut 28 screwed onto the screw shaft 27. The pressure body 25 attached to the tip of the screw shaft 27 can be moved in the axial direction of the screw shaft 27. Similarly to the previous example, the pressing body 25 having a diagonal positional relationship with the front-rear center part of the foot as a boundary protrudes from the side surface of the insertion groove 20a and presses the position shifted from the front and back of the foot from the left and right. It is possible to perform a right and left twisting exercise.

  In the example of FIG. 6, the side pressing means 17 is composed of an out-of-foot front side pressing part 18 a and an in-foot back side pressing part 19 b, but the out-of-foot front side pressing part 18 a and the in-foot back side pressing part 19 b. Is a diagonal positional relationship with the front and rear center part of the foot as a boundary, and it is possible to press the position shifted to the front and rear of the foot from the left and right, and to make the foot perform a twisting motion to the left and right . That is, as long as the side pressing means 17 can press the position shifted to the front and rear of the foot from the left and right to tilt the foot in the left and right direction, the position and number of the pressing portions (18a, etc.) constituting the side pressing means 17 May be arbitrary and is not limited to the above embodiment. Further, there is no particular restriction on the twisting motion between the left and right feet, and for example, the twisting direction may be aligned with the left and right feet, one foot may be twisted, or both feet may be twisted simultaneously.

  Further, the leg holder 4 of the footrest 2 in the massage machine 1 of the present example is provided with leg holding means 30 for pressing and holding each leg placed in each insertion groove 20b from the side (see FIG. FIG. 1 (a)). The leg holding means 30 are disposed on the left and right outer side surfaces of each insertion groove portion 20b and arranged on the left outer side pressing portion 31 for pressing each leg from the outside, and on the left and right inner side surfaces of each insertion groove portion 20b. It is comprised by the leg inner side press part 32 which is provided and presses each leg from the inside (refer FIG.7 (b)), and this leg outer side press part 31 and the leg inner side press part 32 are comprised. The legs are held by the leg holder 4 by sandwiching the legs from the inside and the outside. Specifically, the leg outer side pressing portion 31 and the leg inner side pressing portion 32 are each configured by an airbag 33. The airbag 33 can be expanded and contracted by air supply / exhaust. As shown in FIG. 2, a leg solenoid valve 34 is disposed for each airbag 33 in the air supply line 22 from the air pump 21 as shown in FIG. In addition, the leg solenoid valve 34 is driven and controlled by the control unit 11, and its expansion and contraction operation is controlled. Note that the airbag 33 constituting the leg holding means 30 is an example, and the leg holding means 30 can also be constituted by a fluid bag that expands and contracts by a fluid supply / discharge operation of a fluid composed of a gas other than liquid or air. .

  Then, according to the control of the control unit 11, the legs are held by the leg holding means 30 and the left and right twisting movements of the foot by the side pressing means 17 described above are also performed. According to this, it is possible to perform a left / right twisting movement with respect to the foot while holding the leg (a state where the ankle position is not displaced from side to side), and a more effective stretch effect on the foot. Can be applied. Of course, by pressing the leg with the leg holding means 30 at this time, it is possible to cause the leg to perform a right / left twisting motion while applying a pressing stimulus to the leg, that is, including not only the leg but also the leg ( That is, a stretch effect can be imparted to the lower limb knee). In this way, when the leg is held and fixed, the left / right twisting motion is performed on the foot, and the left / right twisting motion is performed on the foot with both knees straightened. Therefore, for example, even a user who has a knee open outwardly with an O-leg or the like can effectively perform a right / left twisting exercise on the foot.

  FIG. 7 shows a massage machine 1 according to another example of the embodiment of the present invention. Here, the same parts as those in the previous example are denoted by the same reference numerals, description thereof is omitted, and different parts will be described.

  In the footrest 2 of this example, the footrest portion 3 is attached to the leg rest portion 4 on the massage machine main body side so as to be pivotable to the left and right at the heel portion. Thus, the footrest 3 is driven to swing left and right with respect to the leg rest 4. The rotation driving means 35 is controlled by the control unit 11. In this example, the shaft 36 that connects the leg rest 4 and the foot rest 3 is rotated by a motor to rotate the foot rest. 3 is rotated in the left-right direction. The footrest 3 can be rotated in either the left or right direction by driving the motor in the forward or reverse direction. The foot rest 3 is provided with side pressing means 17 (the foot outer side pressing means 18 and the foot inner side pressing means 19), and the leg rest 4 is provided with leg holding means 30.

  In this massage machine 1, a pair of side pressing means 17 (an outer side pressing means 18 and an inner side of the foot) with respect to the foot positioned in the insertion groove 20 of the footrest 3 by the control program of the control unit 11. The side pressing means 19) are pressed from the outside and the inside in the left-right direction, that is, the foot is sandwiched and held from the left and right, and then the foot rest part 3 is held against the leg rest part 4 by the rotation driving means. By rotating the foot left and right, the foot swings left and right around the ankle so that the foot can be twisted left and right. Even in this example, like the previous example, since the foot can be twisted to the left and right, the leg can be stretched with the twisting motion to the left and right. In addition, if the user puts his / her foot on the footrest 3, the control unit 11 can quickly cause the foot to perform a right / left twisting motion automatically. Comfortable massage treatment can be performed with good usability without imposing a complicated operation of fixing the foot with a fixing belt. Of course, by pressing the side surface of the foot directly with the side pressing means 17, it is possible to impart massage-like stimulation to the pressing foot while performing a twisting motion to the left and right.

  Further, by controlling the turning speed of the footrest part 3 to the left and right and the pressing strength by the side pressing means 17 of the footrest part 3 by the control part 11, the unraveling effect of the ankle joint and effective as in the previous example. A stretch effect can also be given to the user. Similarly to the previous example, after the leg is held by the leg holding means 30 of the leg holder 4 by the control unit 11 (the ankle position is not shifted from side to side), You can also twist the left and right, and you can apply a more effective stretch effect to your feet. More specifically, the side pressing means 17 of the footrest unit 3 twists the foot so that the position of the front and rear of the foot moves relatively to the left and right relative to the other positions by the control of the control unit 11 as in the previous example. According to this, the effect of twisting the foot to the left and right is obtained by moving the position of the front and back of the foot relatively to the left and right relative to other positions, and the ankle The effect obtained by swinging the foot left and right around the center can be made synergistic, and an effective twisting motion of the foot from side to side can be expected.

  In the examples of the embodiment described above, although not particularly illustrated, a sole pressing means for pressing the sole may be provided on the bottom surface of the insertion groove 20a of the footrest 3. As the other pressing means, the sole pressing means can suitably use a fluid bag such as an air bag or a pressing body driven to project and retract, and a footrest to make it possible to press a local part of the sole. It can be provided at a local position on the bottom surface of the insertion groove 20 a of the portion 3. When the control unit 11 twists the foot inward, the sole of the foot turns inward, but at this time, if the foot is lifted up by the foot pressing means for pressing the vicinity of the toe, The foot can be twisted from side to side while suppressing the varus of the foot, and more effective stretching can be applied to the foot. Further, for example, when the bottom shape of the insertion groove portion 20a of the footrest portion 3 is formed so as to rise upward from the thumb side to the little finger side, the foot is placed on the footrest portion 3 with the sole placed on the bottom surface of the insertion groove portion 20a. When the control unit 11 causes the foot in this posture to tilt left and right, the left and right sides are twisted while suppressing the varus of the foot. It is possible to exercise and to give a more effective stretch effect to the foot, which is preferable.

  Moreover, although the chair type massage machine 1a provided with the seat part 5 and the backrest part 7 is illustrated in the examples of the embodiment described above, as the massage machine 1 that can cause the foot to perform a right / left twisting operation, For example, it is needless to say that the present invention can be applied to a type of massage machine in which the seat portion 5 and the backrest portion 7 do not exist.
