[Configuration of Massage Machine According to One Embodiment]
Hereinafter, the configuration of the massage machine 1 of the present invention will be described by exemplifying a case where the massage machine 1 is used for a lower limb which is a body part of a user. That is, this is a case where the user sits on a chair and places his / her feet on the massage machine 1 placed on the floor for use. In addition, the concept of the direction used in the following description is assumed to be the same as the concept of the direction when the massage machine 1 is placed on the floor and the foot is placed on the movable support portion 3 as seen from the user. Cases shall be explained as appropriate.

FIG. 1 is a perspective view of a massage machine 1 according to an embodiment of the present invention. FIG. 2 is a perspective view of the massage machine 1 with a part of the base 2 omitted. FIG. 3 is a plan view of the massage machine 1 in which a part of the base 2 is omitted. FIG. 4 is a side view of the massage machine 1 in which a part of the base 2 is omitted. FIG. 5 is a plan view of the drive shaft 8. FIG. 6 is a perspective view of the massage unit 4. FIG. 7 is a side view of the massage section 4. 2 to 4, the side member 2b and the upper member 2c of the base 2 are omitted.
The massage machine 1 of the present invention is mainly supported by a base 2 that is placed on the floor, a movable support portion 3 that supports a body part (foot) that is a part of the user's body, and the movable support portion 3. It has a massage part 4 that massages a body part (foot), a movable support part 3 and a drive mechanism 5 that drives the massage part 4.

  The base 2 has a space inside by a lower member 2a placed on the floor, side members 2b erected from both sides of the lower member 2a, and an upper member 2c that covers the lower member 2a from above. Is configured. The drive mechanism 5 is housed inside the base 2.

  The movable support portions 3 are provided as a pair on the left and right. The movable support portion 3 has a step 3a on which a user's foot is placed. The step 3a is formed in a plate shape that is slightly larger than the sole of a typical adult. In addition, a connecting portion 3b that connects the base 2 and the movable supporting portion 3 is provided on the lower surface of the step 3a at the rear portion and the middle portion in the front-rear direction. One end of the step 3a in the front-rear direction (rear side in this embodiment) is connected to the base 2 via an arm 23 described later, and the other end in the front-rear direction (front side in this embodiment) is described later. It is connected to the base 2 via a guide shaft 25. A displacement prevention member (not shown) formed of a rubber pad or the like for preventing displacement of the body part (foot) with respect to the movable support portion 3 may be provided on the upper surface of the step 3a.

  The movable support portion 3 has an opening 3c that allows the massage portion 4 to project to the body part side with respect to the movable support portion 3. The opening 3c is provided in the middle of the movable support 3 in the front-rear direction, and corresponds to the position of the arch when the foot is placed as a body part in step 3a. Therefore, when the foot is placed on the movable support portion 3, the toes are grounded to the step 3a on the front side of the opening 3c and the heel is grounded to the step 3a on the rear side of the opening 3c. Can be stably supported.

  The drive mechanism 5 includes a motor 6 and a mechanism portion 7 that transmits the driving force of the motor 6 to the movable support portion 3 and the massage portion 4. The motor 6 is fixed to the lower member 2a at the front side of the base 2 and substantially in the center in the left-right direction. The output shaft 6a of the motor 6 faces the left-right direction. The mechanical unit 7 has a drive shaft 8, a crank mechanism 9, a guide unit 10, and a speed reducer 11, which will be described in detail later.

  The mechanical section 7 has a drive shaft 8 which is driven by the motor 6 and rotates in the left-right direction. The drive shaft 8 is rotatably supported by a bearing 20 provided on the lower member 2a on the rear side of the base 2. Further, eccentric shafts 21 that are eccentric with respect to the shaft center 8a of the drive shaft 8 are provided at both left and right ends of the drive shaft 8. The right and left eccentric shafts 21 have different phases around the axis 8a of the drive shaft 8, and specifically, the phases are different by 180 degrees. An arm 23 is rotatably provided on the eccentric shaft 21 via a bearing 22. The arm 23 connects the drive shaft 8 and the movable support portion 3. That is, the eccentric shaft 21 and the arm 23 form the crank mechanism 9. The left arm 23 is connected to the left movable support portion 3, and the right arm 23 is connected to the right movable support portion 3. The movable support portion 3 is rotatably connected to the arm 23 via a pivot 24.

  Further, the mechanism portion 7 has a guide portion 10 that converts the rotation of the drive shaft 8 into the forward / backward movement of the movable support portion 3. The guide unit 10 has a guide shaft 25 whose axial direction is the left-right direction. The guide shaft 25 is provided on the front side of the drive shaft 8 and is rotatably provided on a bearing 26 provided on the lower member 2a at a middle portion in the front-rear direction of the base 2. The base 2 and the movable support portion 3 are connected via the guide shaft 25. The movable support portion 3 is rotatably provided on the guide shaft 25.

  Further, the mechanism portion 7 has a speed reducer 11 that reduces the driving force of the motor 6 and transmits it to the drive shaft 8 and the guide shaft 25. The speed reducer 11 includes a first pulley 31 provided at an axially intermediate portion of the drive shaft 8, a first belt 32 connecting the output shaft 6a of the motor 6 and the first pulley 31, and an axially intermediate portion of the guide shaft 25. It has the 2nd pulley 33 provided in the part, and the 2nd belt 34 which connects the drive shaft 8 and the 2nd pulley 33. Therefore, the driving force of the motor 6 is decelerated and transmitted to the drive shaft 8, and further reduced to the rotational speed of the drive shaft 8 and transmitted to the guide shaft 25. That is, the rotation speed of the drive shaft 8 is faster than the rotation speed of the guide shaft 25. The speed reducer 11 is not limited to the structure using the pulleys 31 and 33 and the belts 32 and 34 described above, and may have another structure. For example, a structure using a worm gear may be used.

  The massage unit 4 is a roller 40 provided on the guide shaft 25. The roller 40 is rotatable integrally with the guide shaft 25 about the axis of the guide shaft 25. Further, a plurality of rollers 40 (two rollers in the present embodiment) are provided in the left-right direction, and the rollers 40 are located corresponding to the left and right feet, respectively. Further, the roller 40 has a plurality of treatment elements 40a having projections, and a holding portion 40b attached to the guide shaft 25 and holding the treatment element 40a. The holding portions 40b form a pair at a predetermined interval in the left-right direction, and the treatment element 40a is held between the pair of holding portions 40b and 40b so as to be rotatable about the left-right axis. A plurality of treatment elements 40a (three in the present embodiment) are provided in the circumferential direction of the guide shaft 25.

  Most of the roller 40 is located below the movable support portion 3 and is located at a position corresponding to the opening 3c. At least a part of the roller 40 projects from the opening 3c toward the body part side with respect to the movable support portion 3. It should be noted that when the movable support portion 3 is moving back and forth, the roller 40 need not always project toward the body part side relative to the movable support portion 3, and a part of the roller 40 is closer to the body part side than the movable support portion 3. It is sufficient if even a little protruding state occurs.

  When the guide shaft 25 rotates, the roller 40 configured as described above is periodically given a massage action to the body part by the treatment element 40a. The center of the roller 40 (that is, the center of the geometric circle of the outer shape of the holding portion 40b) may be eccentric with respect to the axis of the guide shaft 25. In this case, as the guide shaft 25 rotates, the amount of advance of the roller 40 as a whole to the body part side changes. Further, the structure of the roller 40 is not limited to the structure described above. For example, the bottom surface may be formed in a substantially columnar shape that faces the left-right direction, and a massage action may be given such that the side peripheral surface having no protrusion is brought into contact with a body part.

  In the massage machine 1 configured as described above, when the motor 6 is driven, the drive shaft 8 rotates, and the drive force of the motor 6 is transmitted by the mechanism portion 7 so that the guide shaft 25 also rotates. The rotation of the drive shaft 8 causes the arm 23 connecting the eccentric shaft 21 and the movable support portion 3 to rotate around the axis 8a of the drive shaft 8 because the guide shaft 25 restricts the rotation of the arm 23. Therefore, the connecting portion 3b, which is the rear portion of the movable support portion 3, performs vertical movement having a slight front-back component. That is, when viewed as the movable support portion 3 as a whole, as shown in FIG. 4, a swinging motion is performed in which the front side moves up and down along the arrow a with the guide shaft 25 as a fulcrum. Since the phases of the left and right eccentric shafts 21 around the shaft center 8a of the drive shaft 8 are different from each other by 180 degrees, the pair of movable support portions 3 oscillate in opposite directions. The roller 40 provided on the guide shaft 25 rotates together with the guide shaft 25 about the axis of the guide shaft 25.

  According to the massage machine 1 that operates as described above, the toe side of the foot supported by the movable support portion 3 moves up and down with the heel side as the fulcrum. The directions in which the left and right feet move are opposite to each other. If the rotation of the motor 6 is increased and the movable support 3 is swung quickly, the lower limb can be vibrated, and the muscles of the ankle and the calf can be loosened. By slowing the rotation of the motor 6 and slowly swinging the movable support portion 3, it is possible to perform an exercise for stretching the muscle of the Achilles tendon.

  Further, it is preferable that the movable support portion 3 is provided so as to be inclined such that the front side is located closer to the body part side (upper side) than the rear side in a state where the front side in the advance / retreat range is most retracted (lowered). With this configuration, it is possible to cause the body part to perform a sufficient motion without increasing the range in which the movable support portion 3 moves back and forth. For example, when the foot is placed on the movable support portion 3, the ankle can be sufficiently dorsiflexed since the toe can be further raised from the raised state.

  Alternatively, the movable support portion 3 may be provided so as to be inclined so that the front side is located on the opposite side (lower side) to the body part than the rear side when the front side in the advance / retreat range is most advanced (raised). With such a configuration, it is possible to cause the body part to perform a sufficient motion without increasing the range in which the movable support portion 3 moves back and forth. For example, when the foot is placed on the movable support portion 3, the ankle can be fully flexed because the toe can be further lowered from the lowered state.

  A control means (not shown) having a microcomputer may be provided to automatically change the rotation speed and rotation direction of the motor 6 according to a program. By driving the motor 6, the lower limb, which is a body part, can be forcibly moved. Further, the arch 40 can be given a massage action by the roller 40. In this way, the lower limbs, which are body parts, can be exercised and massaged in a combined manner.

[Example of use of massage machine]
Hereinafter, a usage example of the massage machine 1 of the present invention will be described.
For example, the massage machine 1 can be placed on the floor and used while sitting on a chair. In this case, the left and right feet are placed on the pair of movable support portions 3 and used while the knees are bent at about 90 degrees. Further, the massage machine 1 can be placed on the floor and used in a standing state. In this case, with the knees extended, the left and right feet are placed on the pair of movable support portions 3 for use. Further, the massage machine 1 can be placed on the floor and used while sitting on the floor. In this case, the left and right legs (calves) are placed and used on the pair of movable support portions 3 with the knees extended. Further, the massage machine 1 can be placed on the floor or the seating surface of a chair and used while sitting on the massage machine 1. In this case, the buttocks are placed and used so as to straddle the pair of movable supporting portions 3. That is, the left hip is placed on the left movable support portion 3 and the right hip is placed on the left movable support portion 3 for use.

[Configuration of Massage Machine According to Modification 1]
Hereinafter, a modified example 1 of the massage machine of the present invention will be described.
FIG. 8 is a side sectional view of the massage machine 100 according to the first modification of the present invention. FIG. 9 is a side sectional view of the massage machine 100 according to the first modification of the present invention. FIG. 8 shows a state where the movable support portion 3 is most advanced to the body part side, and FIG. 9 shows that the eccentric shaft 21 rotates clockwise about the axis 8a of the drive shaft 8 from the state of FIG. It shows a state of being rotated once. 8 and 9 are side cross-sectional views passing through the inside of the opening 3c.
The difference from the massage machine 1 described above is that the movable support portion 3 moves back and forth without changing the angle of the step 3a with respect to the floor surface. Below, about the same composition as massage machine 1, the same numerals are attached and the explanation is omitted.

  Like the massage machine 1 described above, the massage machine 100 mainly includes a base 2 placed on the floor, a movable support portion 3 that supports a body part (foot) that is a part of the user's body, and a movable support. A massage unit 4 that massages a body part (foot) supported by the unit 3 and a drive mechanism 50 that drives the movable support unit 3 and the massage unit 4 are provided. The drive mechanism 50 includes a motor 6 (see FIG. 3) and a mechanism portion 70 that transmits the driving force of the motor 6 to the movable support portion 3 and the massage portion 4.

  The base 2 includes a drive shaft 8 which is driven by a motor 6 and which rotates in the left-right direction as an axial direction, a driven shaft 51 which is driven by rotation of the drive shaft 8 and which is rotated in the left-right direction as an axial direction, and a massage section 4 And a rotating shaft 52 having a left-right direction as an axial direction for rotatably supporting. A belt 53 is provided between the drive shaft 8 and the driven shaft 51, and when the drive shaft 8 rotates, the driven shaft 51 also rotates in conjunction. A belt 54 is provided between the drive shaft 8 and the rotary shaft 52, and when the drive shaft 8 or the driven shaft 51 rotates, the rotary shaft 52 also rotates in conjunction. The structure for rotating the drive shaft 8, the driven shaft 51, and the rotary shaft 52 in conjunction with each other is not limited to the structure using the belts 53 and 54 described above, and may be another structure. For example, a structure using a worm gear may be used.

  The drive shaft 8 and one end of the movable support portion 3 in the front-rear direction are connected by a crank mechanism 9. Further, the driven shaft 51 and the other end portion in the front-rear direction of the movable support portion 3 are connected by another crank mechanism 9. These crank mechanisms 9 and 9 have the same structure as the crank mechanism 9 of the massage machine 1. Further, a guide portion 55 that converts the rotation of the drive shaft 8 into the advancing / retreating motion of the movable support portion 3 is provided. The base 2 is provided with a guide groove 56 that opens in the vertical direction, and the connecting portion 3b provided on the lower surface of the step 3a is inserted into the guide groove 56. That is, the guide groove 55 and the connecting portion 3b constitute the guide portion 55. As described above, the mechanism unit 70 includes the drive shaft 8, the driven shaft 51, the rotating shaft 52, the crank mechanism 9, the guide unit 55, and the belts 53 and 54.

  In the massage machine 100 configured as described above, when the motor 6 is driven, the drive shaft 8 rotates, and the driving force of the motor 6 is transmitted by the mechanism unit 70, and the driven shaft 51 and the rotary shaft 52 also rotate. As the drive shaft 8 rotates, the arm 23 that connects the eccentric shaft 21 and the movable support portion 3 is restricted in rotation by the guide portion 55, so that the arm 23 circulates around the drive shaft 8 and the driven shaft 51, respectively. . Therefore, the movable support portion 3 moves up and down along the arrow b without changing the angle of the step 3a with respect to the floor surface. Further, the roller 40 provided on the rotating shaft 52 rotates together with the rotating shaft 52 about the axis of the rotating shaft 52.

[Configuration of Massage Machine According to Modification 2]
Hereinafter, a modified example 2 of the massage machine of the present invention will be described.
FIG. 10 is a perspective view of a massage machine 200 in which a part of the base 2 according to the modified example 2 of the present invention is omitted. FIG. 11 is a plan view of the massage machine 200 in which a part of the base 2 according to the modified example 2 of the present invention is omitted. FIG. 12 is a side view of the massage machine 200 in which a part of the base 2 according to the modified example 2 of the present invention is omitted.
The difference from the massage machine 1 described above is that the movable support portion 3 is connected to the base 2 at both ends in the front-rear direction. Below, about the same composition as massage machine 1, the same numerals are attached and the explanation is omitted.

  The massage machine 200, like the massage machine 1 described above, mainly includes a base 2 that is placed on the floor, a movable support portion 3 that supports a body part (foot) that is a part of the user's body, and a movable support. A massage unit 4 that massages a body part (foot) supported by the unit 3 and a drive mechanism 5 that drives the movable support unit 3 and the massage unit 4 are provided. The drive mechanism 5 includes a motor 6 and a mechanism portion 80 that transmits the driving force of the motor 6 to the movable support portion 3 and the massage portion 4. The mechanical unit 80 has a drive shaft 8, a crank mechanism 9, a guide unit 60 (guide shaft 61), a rotary shaft 62, and a speed reducer 11, which will be described in detail later.

  On the lower surface of step 3a, connecting portions 3b that connect the base 2 and the movable support portion 3 are provided at the rear end portion and the front end portion. One end side of the step 3a in the front-rear direction (rear side in this embodiment) is connected to the base 2 via the arm 23, and the other end side in the front-rear direction (front side in this embodiment) is the guide portion 60 ( It is connected to the bearing 63 by a guide shaft 61).

  The mechanism unit 80 has a guide unit 60 that converts the rotation of the drive shaft 8 into the forward / backward movement of the movable support unit 3. The guide portion 60 has a guide shaft 61 whose axial direction is the left-right direction. The guide shaft 61 is provided on the front side of the drive shaft 8 and rotatably provided at a front end portion of the base 2 on a bearing 63 provided on the lower member 2a. The base 2 and the movable support portion 3 are connected via the guide shaft 61. The movable support portion 3 is rotatably provided on the guide shaft 61.

  Further, the mechanical unit 80 has a decelerator 11 that decelerates the driving force of the motor 6 and transmits it to the drive shaft 8 and the rotary shaft 62. The decelerator 11 includes a first pulley 31 provided at an intermediate portion of the drive shaft 8 in the axial direction, a first belt 32 connecting the output shaft 6 a of the motor 6 and the first pulley 31, and an intermediate portion of the rotary shaft 62 in the axial direction. It has the 2nd pulley 33 provided in the part, and the 2nd belt 34 which connects the drive shaft 8 and the 2nd pulley 33. Therefore, the driving force of the motor 6 is decelerated and transmitted to the drive shaft 8, and further reduced to the rotational speed of the drive shaft 8 and transmitted to the rotation shaft 62. That is, the rotation speed of the drive shaft 8 is faster than the rotation speed of the rotation shaft 62. The speed reducer 11 is not limited to the structure using the pulleys 31 and 33 and the belts 32 and 34 described above, and may have another structure. For example, a structure using a worm gear may be used.

  The massage unit 4 is a roller 40 having a rotary shaft 62 whose axial direction is the left-right direction. The roller 40 is rotatable around the axis of the rotary shaft 62. Further, a plurality of rollers 40 (two rollers in the present embodiment) are provided in the left-right direction, and the rollers 40 are located corresponding to the left and right feet, respectively. Further, as shown in FIGS. 6 and 7, the roller 40 has a plurality of treatment elements 40a having protrusions and a holding portion 40b attached to the rotating shaft 62 and holding the treatment elements 40a. There is. The holding portions 40b form a pair at a predetermined interval in the left-right direction, and the treatment element 40a is held between the pair of holding portions 40b and 40b so as to be rotatable about the left-right axis. A plurality of treatment elements 40a (three in the present embodiment) are provided in the circumferential direction of the rotating shaft. In the roller 40 configured as described above, when the rotating shaft 62 rotates, the massaging action is periodically given to the body part by the treatment element 40a.

  In the massage machine 200 configured as described above, when the motor 6 is driven, the drive shaft 8 rotates, and at the same time, the drive force of the motor 6 is transmitted by the mechanism portion 80 and the rotary shaft 62 also rotates. The rotation of the drive shaft 8 causes the arm 23 connecting the eccentric shaft 21 and the movable support portion 3 to rotate around the axis 8a of the drive shaft 8 because the rotation of the arm 23 is restricted by the guide shaft 61. Therefore, the connecting portion 3b, which is the rear portion of the movable support portion 3, performs vertical movement having a slight front-back component. That is, when viewed as the movable support part 3 as a whole, as shown in FIG. 12, a swinging motion is performed in which the rear side moves up and down along the arrow c with the guide shaft 61 as a fulcrum. Since the phases of the left and right eccentric shafts 21 around the shaft center 8a of the drive shaft 8 are different from each other by 180 degrees, the pair of movable support portions 3 oscillate in opposite directions. Further, the roller 40 rotates about the axis of the rotation shaft 62.

  According to the massage machine 200 that operates as described above, the foot supported by the movable support portion 3 moves up and down on the heel side with the toe side as the fulcrum. The directions in which the left and right feet move are opposite to each other. If the motor 6 is rotated at a high speed and the movable support 3 is swung quickly, the lower limbs can be vibrated and the ankle and calf muscles can be loosened. By slowing the rotation of the motor 6 and slowly swinging the movable support portion 3, it is possible to perform an exercise for stretching the muscle of the Achilles tendon. Moreover, since the movable support portion 3 is connected to the base 2 at both front and rear ends, the movable support portion 3 can be stably operated. Also, abnormal noise can be reduced, and the durability of the massage machine 200 is also improved.

[Application example of massage machine]
