It is a schematic diagram which shows the timing to perform. In the present embodiment, the massager is described as a massager that massages the legs and feet of the user. However, the leg of the user is incorporated as part of a chair-type massager that treats the back and arms of the user. You can also treat the legs and feet. The up and down direction used in the description is the up and down direction in FIGS. 1 and 2. Similarly, for the front and back direction, the front side of the paper in FIGS. Similarly, in the left-right direction, the right direction in FIGS. 1 and 2 is the left direction, and the left direction in FIGS. 1 and 2 is the right direction. These directions are the same as the viewpoint when the user places the lower limb on the massage machine of the present invention.

  As shown in FIG. 1 and FIG. 2, the massage machine has a foot support 1 for placing the foot of the user, and a leg support above the foot support 1 to support the leg of the user. In order to support the left and right lower limbs of the user with the leg support part 3, a groove is formed in the leg support part 3 so as to be recessed from the front to the rear. As shown in FIG. 2, the foot placement unit 1 incorporates the sole treatment unit 2 shown in FIG. 3 for treating the back side of the foot of the user. In addition, although the internal structure of the massage machine is exposed in FIG. 1 and the like, various members constituting the massage machine are covered with thin and soft members such as leather and cloth, and the user actually The internal composition cannot be seen directly when used.

  In addition, when the massage machine is incorporated as a part of the chair type massage machine, the massage machine is provided below the seat part, and can be rotated with respect to the seat part or can be stopped at a predetermined angle with respect to the seat part. It can also be made extensible and retractable by a telescopic mechanism along the longitudinal direction of the leg of the user at a predetermined position.

  The foot placement portion 1 is a member for placing the foot portion of the user and is provided below the leg support portion 3. In order to place the left and right foot portions of the user on the foot placement portion 1, a groove is formed in the foot placement portion 1 so as to be recessed downward from above. By this groove, when the user places the left and right foot portions on the respective foot placement portions 1, the foot portion of the user is in contact with the bottom wall 1 a on which the sole of the user contacts, It is surrounded by an outer wall 1b facing the outside of the person's foot and an intermediate wall 1c facing the inside of the person's foot.

  As shown in FIG. 2, the sole treatment unit 2 is a member that is incorporated in the foot placement unit 1 and treats the sole of the user. As shown in FIG. 3, the sole treatment unit 2 includes a power source 21 for driving the sole treatment unit 2, a rotary shaft 22 rotated by the power source 21, and a rotary treatment unit 23 fixed to the rotary shaft 22. Etc. The sole treatment unit 2 is provided to be selected by the user using the operation unit R such as an operation display panel or a switch, and is operated via the control unit CP or the like. Moreover, it is preferable that the sole treatment part 2 and the operation part R operate | move with the electric power supplied from external power sources, such as an indoor outlet. Then, it is possible to adjust the treatment method, the treatment time, and the like on the sole by various programs built in the storage unit M or the like that is connected to and communicates with the control unit CP.

  As illustrated in FIGS. 2 and 3, the power source 21 is an electric motor or an electric motor included in front of the footrest 1. The power source 21 can convert electric energy into mechanical energy, and can rotate a shaft provided in the power source 21 using electromagnetic interaction or the like by electric power supplied from an external power source or the like. The power source 21 is preferably sequence-controlled by the control unit CP or the like so that it can perform not only rotation in one direction but also rotation in the opposite direction.

  The rotating shaft 22 is a member that is disposed from the inner side to the outer side in the lateral width direction of the foot placement portion 1 and that can rotate in conjunction with a shaft provided in the power source 21 via a bevel gear or the like. is there. The rotating shaft 22 is provided below the sole of the user and extends from the intermediate wall 1c to the outer wall 1b of the footrest 1 and has an elongated cylindrical shape. And it is preferable that the rotating shaft 22 only rotates in a predetermined place, and does not move to the front-back direction of the footrest 1. Further, the rotation direction of the rotary shaft 22 can be rotated from the front to the rear or from the rear to the front by the forward rotation and the reverse rotation of the power source 21.

  The rotation treatment unit 23 is a member that treats the sole of the user in conjunction with the rotation shaft 22 fixed to the rotation shaft 22. The rotation treatment unit 23 is fixed in the vicinity of the center of each of the left and right rotation shafts 22. The main body portion 231 fixed to the rotation shaft 22 and the surface of the main body portion 231 are projected in the direction of the rotation shaft 22. A first protrusion 232 having a predetermined width along the surface and a second protrusion 233 that protrudes from the surface of the main body 231 and is wider along the rotation axis direction 22 than the first protrusion 232. The

  The main body 231 has a substantially cylindrical shape, and is fixed to the rotating shaft 22 by a fixing method such as adhesion, fitting, locking, and screwing.

  Both the first protrusion 232 and the second protrusion 233 are members that protrude from the outer peripheral surface of the main body 231 and press the sole of the user to be treated. The width of the second protrusion 233 in the left-right direction is longer than the width of the second protrusion 233. Thus, when the widths of the first protrusion 232 and the second protrusion 233 are different, the area for pressing the sole of the user is different, and the pressure on the treated sole changes. Therefore, various treatments can be performed on the soles.

  The first protrusion 232 and the second protrusion 233 are loose from the main body 231 such that the cut surface when cut by a surface perpendicular to the rotation shaft 22 is between a substantially U shape and a substantially V shape. It has a shape that rises as a curved surface and converges to the main body portion 231 as a gently curved surface through the arc-shaped first projection top 232T and the second projection top 233T. Thus, since the surface shape of the 1st projection part 232 and the 2nd projection part 233 is drawing the gentle curved surface, it begins to press the foot of a user weakly, and it presses gradually gradually, and the 1st It is possible to apply a continuous strength to the pressing force that is most strongly pressed in the vicinity of the protrusion top portion 232T and the second protrusion top portion 233T, and then gradually presses weakly but does not press at the end.

  And the 1st projection part 232 and the 2nd projection part 233 are arrange | positioned on the predetermined surface perpendicular | vertical to the rotating shaft 22, as shown in FIG.3 and FIG.4. This means that there is at least one surface that simultaneously cuts the first protrusion 232 and the second protrusion 233 when cutting along a plane perpendicular to the rotation shaft 22. And the positional relationship with respect to the main-body part 231 of the 2nd projection part 233 is shown. By arranging the first projecting portion 232 and the second projecting portion 233 so as to be in such a positional relationship, the area to be pressed is small while treating the same place on the sole of the user. The first protrusion 232 can be pressed relatively strongly, the second protrusion 233 having a large pressing area can be pressed relatively weakly, and different treatments can be performed in the width direction of the sole of the user. Can do.

  Further, specifically, the second protrusion 233 is located on the opposite side of the first protrusion 232 with respect to the rotation shaft 22. That is, the first protrusion 232 and the second protrusion 233 are positioned 180 degrees opposite to each other via the rotation shaft 22. Thereby, it becomes possible to treat the sole of the user with a certain rhythm. In the present embodiment, one first protrusion 232 and two second protrusions 233 are provided so as to protrude from one main body 231. In other embodiments, the first protrusion 232 and A plurality of second protrusions 233 can also be provided.

  As shown in FIGS. 3 and 4, the center of the first projecting portion 232 in the lateral direction is inside the center of the second projecting portion 233 in the lateral width direction, that is, the power source 21 of the sole treatment unit 2. A first protrusion 232 and a second protrusion 233 are disposed so as to be closer to the side. By arranging the first projecting portion 232 and the second projecting portion 233 in this manner, the first projecting portion 232 having a small area for pressing the arch inside the sole of the user is relatively stronger. It can be pressed and can be pressed relatively weakly by the second protrusion 233 having a large area that presses the outside of the foot of the user. Based on the undulation of the foot in the width direction of the foot of the user Different treatments can be performed. And by making the 2nd projection part 233 into a shape flatter than the 1st projection part 232 in this way, even on the little finger side which is the outside of the thumb side and the little finger side of the arch part where the meat is thin and easy to feel pain The treatment effect can be enhanced by performing massage while reducing pain.

  When the rotation treatment portion 23 fixed to the rotation shaft 22 is cut along a plane perpendicular to the rotation shaft 22 so as to pass through the first projection portion 232 and the second projection portion 233, as shown in FIG. The height from the center of the rotation shaft 22 to the first protrusion top 232T of the first protrusion 232 is higher than the height from the center of the rotation shaft 22 to the second protrusion top 233T of the second protrusion 233. Yes. In this way, by increasing the height of the first protrusion top 232T of the first protrusion 232, the first protrusion 232 is more strongly pressed when pressing the sole of the user. The treatment can be performed, the treatment with the second protrusion 233 can be sharpened, and various treatments can be performed.

  At this time, the height from the center of the rotation shaft 22 to the first protrusion top 232T of the first protrusion 232 is 1 higher than the height from the center of the rotation shaft 22 to the second protrusion top 233T of the second protrusion 233. It is preferably 0.05 to 1.30 times higher, and more preferably 1.10 to 1.20 times higher. If the height relationship from the center of the rotating shaft 22 to the first protrusion top portion 232T and the second protrusion top portion 233T is within this range, the first protrusion portion 232 and the second protrusion portion 233 treat the first protrusion portion 233 while sharpening it. It is possible to provide an appropriate pressure difference in which the treatment by the one protrusion 232 does not become relatively strong and the treatment by the second protrusion 233 does not become relatively weak.

  And as shown in FIG. 4, the 2nd protrusion top part 233T of the 2nd protrusion part 233 inclines gently so that it may become low toward the outer side from the inner side in the horizontal width direction of the footrest part 1. As shown in FIG. The second protrusion 233 is provided with a width that is wide from the inner side to the outer side in the lateral width direction of the foot placement part 1, and the second protrusion top part 233T of the second protrusion part 233 is provided so as to be inclined. Therefore, it is possible to treat the sole with the same pressing force along the inclination of the sole of the user's foot while alleviating the pain due to the treatment on the portion where the thickness varies from the arch to the outside of the sole. .

  At this time, the angle at which the second protrusion top 233T of the second protrusion 233 is inclined is preferably 2 to 10 degrees, and more preferably 3 to 7 degrees. If the second protrusion top portion 233T of the second protrusion 233 is inclined at an angle in this range, the inclination angle is substantially the same as the inclination angle from the arch side to the outside of the foot of the user. Treatment can be performed with the same pressing force.

  As shown in FIG. 3, on the outer side of the sole treatment part 23 on the rotating shaft 22, the fixing part 24 having a concave surface curved downward is interposed through a cylindrical member constituting a part of the fixing part 24. The rotary shaft 22 is inserted. As shown in FIG. 2, the fixing portion 24 is a part of the leg frame F that forms a skeleton of the footrest portion 1 and the leg support portion 3 by combining a plurality of pipe-shaped members, that is, the front-rear direction. The curved concave surface is brought into contact with the skeleton portion incorporated in the foot placement portion 1 extending in the direction, and is fixed to the leg frame F. By providing the fixing portion 24, it is possible to suppress blurring that the rotation treatment portion 23 moves slightly in the vertical direction and the front-back direction when the rotation treatment portion 23 rotates around the rotation shaft 22, and the first protrusion 232 and the second projection portion 232. The pressing force of the protrusion 233 on the sole of the user can be made constant.

  The leg support unit 3 is located above the foot placement unit 1 and has a groove formed in the leg support unit 3 so as to be recessed from the front to the rear in order to support the left and right legs of the user. Specifically, it includes a back wall 3a facing the calf area of the user, an outer wall 3b facing the outside of the leg of the user, and an intermediate wall 3c facing the inside of the leg of the user. . The outer wall 3b of the leg support portion 3 forms a plane that is substantially the same as the outer wall 1b of the footrest portion 1, and the intermediate wall 3c of the support portion 3 is substantially the same as the intermediate wall 1c of the footrest portion 1. A flat surface can be formed to accommodate the lower limbs of the user.

  The foot inflation / deflation bag 4 expands when air is supplied from the compressor portion C via the electromagnetic valve V, and contracts when the supplied internal air is exhausted via the electromagnetic valve V. It is a bag-shaped member and is a member used for the foot of the user. As shown in FIG. 1 and FIG. 2, the foot inflatable bag 4 includes an inner foot inflatable bag 4 a and an outer foot inflatable bag 4 b, and the inner foot inflatable bag 4 a is an intermediate wall of the support portion 3. 3c and the intermediate wall 1c of the footrest 1 are provided near the boundary, and the outer foot expansion / contraction bag 4b is provided near the boundary of the outer wall 3b of the leg support 3 and the outer wall 1b of the footrest 1 ing. When inflated, the inner foot inflatable bag 4a presses the inner side surface, and the outer foot inflatable bag 4b presses the outer side surface of the user's foot. Do not press the inner and outer sides of the foot.

  The leg expansion / contraction bag 5 expands when air is supplied from the compressor section C through another electromagnetic valve (not shown), and the supplied internal air is exhausted through the other electromagnetic valve. It is a bag-shaped member which shrinks by this, and is a member used for a leg part of a user. As shown in FIGS. 1 and 2, one leg expansion / contraction bag 5 is provided on the back portion 3 a of the leg support portion 3, and two on the outer wall 3 b and the intermediate wall 3 c. These inflatable and inflatable bags 5 are treated by pressing the calf side, the outer side surface, and the inner side surface, which are the back side of the legs of the user when inflated, and the legs of the user when contracted. Treatment is not performed without pressing the outer side surface and the inner side surface.

  The foot inflatable bag 4 and leg inflatable bag 5 are preferably made of a polymer material that has stretchability and is excellent in air tightness, such as polyurethane, 6,6-nylon, 6- More preferably, nylon, ABS, or silicone resin is used alone or in combination of two or more.

  FIG. 5 shows the expansion / contraction of the foot expansion / contraction bag 4 composed of the inner foot expansion / contraction bag 4a and the outer foot expansion / contraction bag 4b by the air pipe connected from the compressor section C via the electromagnetic valve V. The block diagram of a mechanism and the control mechanism which controls the drive of the power source 21 which rotates the rotating shaft 22 to which the expansion / contraction of the inflatable bag 4 for foot and the rotation treatment part 23 was fixed is shown. The control unit CP starts from the operation of the operation unit R such as an operation display panel or a switch, and the power source 21 that rotates the rotating shaft 22 to which the rotation treatment unit 23 is fixed is rotated in a predetermined direction such as normal rotation or reverse rotation. Based on the rotation information of the rotary shaft 22 obtained from the detection unit S such as an incremental or absolute rotary encoder attached to the rotary shaft 22 rotated by the power source 21 and rotated by a predetermined amount. Control part C and solenoid valve V. Thereby, it can control so that the timing which the expansion / contraction bag 4 for legs expands / contracts becomes a predetermined timing. Further, the control unit CP receives the user from the storage unit M in which a treatment program such as a forward rotation speed or a reverse rotation speed, a rotation time, and a switching timing is stored with respect to the operation of the rotation shaft 22 and the rotation treatment unit 23. A predetermined treatment program is extracted by operating the operation unit R, and various controls of the power source 21 are performed. Further, in FIG. 5, for the sake of simplicity, only the inflatable bag 4 for pressing the right foot of the user is shown, but the inflatable bag 4 for pressing the left foot of the user has the same configuration. Have. And also about the expansion / contraction bag 5 for a leg which presses a user's right and left leg, air is supplied from the compressor part C via other air piping and other several electromagnetic valves, and a detection part is needed as needed. Based on the rotation information of the rotating shaft 22 obtained from S, the timing at which the leg inflating / deflating bag 5 inflates and contracts is controlled by the control unit CP to be a predetermined timing.

  Here, the solenoid valve V is an foot for an inflow port (not shown) that is connected to the compressor section C through an air pipe shown in FIG. 5, and an inflatable bag 4a for an inner foot and an inflatable bag 4b for an outer foot. It consists of a three-way valve having an outlet (not shown) that is connected to the expansion / contraction bag 4 and an open opening that is not connected to any of them. The solenoid valve V is a press-fitted state in which the inlet side is opened in either the holding state by closing the open valve, the exhaust state by opening the open valve, or the holding state / open state by the internal three-way valve operation Transition to various states. The same applies to a plurality of other solenoid valves connected to the leg expansion / contraction bag 5 via another air pipe.

  The control unit CP synchronizes the timing at which the first projection 232 and the second projection 233 of the rotation treatment unit 23 come into contact with the back side of the foot of the user and the timing at which the foot inflation / deflation bag 4 inflates, Control which synchronizes the timing which the 1st projection part 232 and the 2nd projection part 233 of the rotation treatment part 23 leave | separate from the back side of a to-be-treated person's foot | leg, and the timing which the expansion / contraction bag 4 for legs shrink | contracts is performed. Specifically, based on the rotation information such as the rotation speed and the rotation speed about the rotation shaft 22 obtained from the detection unit S such as a rotary encoder attached to the rotation shaft 22 rotated by the power source 21, a predetermined value is applied to the rotation shaft 22. Since the position information of the first protrusion 232 and the second protrusion 233 of the rotation treatment unit 23 fixed at the position is grasped, for example, the first protrusion 232 rotates by an angle of 20 to 30 degrees from the horizontal direction. When the control unit CP opens the inlet side and outlet side valves of the electromagnetic valve V and closes the opening side valve when the contact portion starts to contact the sole side of the user, the compressor portion From C, air is press-fitted into the inflatable bag 4a for outer legs and the inflatable bag 4b for outer legs to inflate, and the first protrusion 232 of the rotary treatment portion 23 comes into contact with the back side of the foot portion of the user. Timing and foot Chijimibukuro 4 is the timing of expansion are synchronized. Similarly, with respect to the second protrusion 233, the timing at which the second protrusion 233 of the rotation treatment unit 23 abuts on the back side of the foot of the user and the timing at which the foot inflating / deflating bag 4 is inflated. It is possible to synchronize. Therefore, the back side of the foot of the user is pressed by the inflatable bag 4a and the inflatable bag 4b for the outer foot, and the sole is pressed by the first protrusion 232 of the rotary treatment unit 23. Therefore, it is not necessary for the user to bother to push the foot against the rotating treatment part 23 for the sole, so that the treatment effect can be sufficiently enhanced. On the other hand, for example, when the first protrusion 232 is rotated by an angle of 150 to 160 degrees from the horizontal direction and begins to move away from the sole side of the user, the control unit CP closes the valve on the inlet side of the electromagnetic valve V. By controlling to open the valve on the outlet side and the opening side, the air press-fitted into the inflatable bag 4a for the inner foot and the inflatable bag 4b for the outer foot is exhausted and contracted. The timing at which the first projecting portion 232 of the portion 23 moves away from the back side of the foot portion of the user is synchronized with the timing at which the foot inflation / deflation bag 4 contracts. Similarly, with respect to the second protrusion 233, the timing at which the second protrusion 233 of the rotation treatment portion 23 is separated from the back side of the foot of the user and the timing at which the foot inflatable bag 4 contracts are synchronized. Is possible. For this reason, the back side of the foot of the user is released from the pressing of the inner foot expansion / contraction bag 4a and the outer foot expansion / contraction bag 4b, and the foot pressing treatment is performed by the first projecting portion 232 of the rotating treatment portion 23. Since it will be stopped, a feeling of release is obtained compared to when pressing treatment is performed, and the treatment can be sharpened. In addition, as described above, since the width and height of the first protrusion 232 and the second protrusion 233 are different, complicated and sharp treatment can be performed.

  Next, a series of operations relating to treatment of the foot of the user will be described.

  The user places his / her foot on the foot rest 1 and selects foot treatment using the operation unit R such as an operation display panel or selects a treatment course in which foot treatment is incorporated. Then, the power source 21 is operated by the control unit CP, and the rotating shaft 22 rotates in conjunction with the power source 21.

  And the sole treatment part 2 fixed to the rotating shaft 22 is also treated with the first protrusion 232 and the second protrusion 233 protruding from the main body 231 of the sole treatment part 2 together with the rotating shaft 22. The inner leg inflatable bag 4a and the outer leg inflatable bag 4b start to rotate from a state where they are not in contact with the back side of the person's foot. Thereafter, based on the rotation information about the rotation shaft 22 obtained from the detection unit S, as shown in FIG. 6A, the first protrusion 232 presses the sole of the user and the inner foot is inflated or contracted. The treatment effect can be sufficiently enhanced by inflating the bag 4a and the expansion / contraction bag 4b for the outer foot and pressing the instep side of the foot. Subsequently, as shown in FIG. 6 (b), the first protrusion 232 moves away from the sole of the user, and the inner foot inflatable bag 4a and the outer foot inflatable bag 4b contract, By releasing the instep side from the pressure, a feeling of release can be obtained compared to when pressure treatment is performed, the treatment can be sharpened, and a hand-feeling feeling by a human hand can be imparted.

  And after that, as the rotating shaft 22 continues to rotate, the second protrusion 233 presses the sole of the user as shown in FIG. The treatment effect can be sufficiently enhanced by inflating the foot inflatable bag 4b and pressing the instep side of the foot. Subsequently, as shown in FIG. 7 (b), the second protrusion 233 moves away from the sole of the user, and the inner foot inflatable bag 4a and the outer foot inflatable bag 4b contract, By releasing the instep side from the pressure, a feeling of release can be obtained compared to when the pressure treatment is performed, and the treatment can be sharpened. In this manner, the pressure treatment by the first protrusion 232 and the pressure treatment by the second protrusion 233 are alternately repeated in synchronization with the expansion of the inner foot inflatable bag 4a and the outer foot inflatable bag 4b. The treatment to the foot can be performed by the user performing an operation to stop the treatment on the operation display panel or the treatment is automatically ended by the control unit CP based on the treatment program stored in the storage unit M. finish. The first protrusion 232 and the second protrusion 233 projecting from the main body 231 of the sole treatment unit 2 are not in contact with the back side of the user's foot, and the inner foot inflatable bag 4a and The treatment is terminated in a state where the outer foot inflatable bag 4b is contracted.

  8 (a) and 8 (b), the timing of expansion and contraction of the inner foot expansion / contraction bag 4a and the outer foot expansion / contraction bag 4b, and the first protrusion 232 and the second protrusion of the rotation treatment unit 23 are illustrated. The timing at which the part 233 separates from the back side of the foot of the user is schematically shown, and the first protrusion 232 and the second protrusion 233 of the rotation treatment part 23 touch the back side of the foot of the user. The contact timing is synchronized with the expansion timing of the inner foot expansion / contraction bag 4a and the outer foot expansion / contraction bag 4b, and the first protrusion 232 and the second protrusion 233 of the rotation treatment portion 23 are the foot portions of the user. The timing of separating from the back side of the foot is synchronized with the timing of contraction of the inner foot inflatable bag 4a and the outer foot inflatable bag 4b. Moreover, in FIG.8 (b), the timing which the 1st projection part 232 and the 2nd projection part 233 of the rotation treatment part 23 contact | abut on the back side of a to-be-treated person's foot, the inflatable bag 4a for an inner leg, and an outer leg When the inflation timing of the inflatable bag 4b is synchronized, the rotational speed of the rotating shaft 22 is made slower than in FIG. 8A to hold the foot of the user and perform the pressure treatment. You can take a long time.

  In other embodiments, when projections such as the first projection 232 and the second projection 233 in the above embodiment are cut along a plane perpendicular to the rotation shaft 22, the first projection in the above embodiment. It is also possible to make the shape asymmetric in the front-rear direction of the top corresponding to the top 232T and the second protrusion top 233T. In this way, by making the protrusion asymmetrical in the front-rear direction, when the rotating shaft 22 is rotated forward and reversely, the force applied to the user on the back side of the foot is applied. Because of the difference, more complex and diverse treatments can be performed. In this embodiment, a plurality of protrusions can be provided as in the above embodiment.
