[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 foot is placed on the massage machine 1 placed on the floor and used while sitting on a chair. In addition, the concept of the direction used in the following description shall be the same as the concept of the direction when the massage machine 1 is placed on the floor and the foot is viewed from the user who places the foot on the movable support portion 3. The case will be described as appropriate.

FIG. 1 is a perspective view of a massage machine 1 according to one embodiment of the present invention. FIG. 2 is a perspective view of the massage machine 1 in which a part of the base 2 is 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 unit 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 supported mainly by the base 2 placed on the floor, the movable support 3 for supporting a body part (foot) that is a part of the user's body, and the movable support 3. It has a massage part 4 for massaging a body part (foot), and a drive mechanism 5 for driving the movable support part 3 and 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 covering the lower member 2a from above. It is configured. The drive mechanism 5 is housed inside the base 2.

  The movable support portions 3 are provided in pairs on the left and right. The movable support 3 has a step 3a for placing the user's foot. The step 3a is formed in a plate shape slightly larger than the sole of a general adult. Further, on the lower surface of the step 3a, a connecting portion 3b for connecting the base 2 and the movable supporting portion 3 is provided at a rear portion and an intermediate portion in the front-rear direction. One end of the step 3a in the front-rear direction (rear side in the present 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 the present embodiment) is described later. It is connected to the base 2 via a guide shaft 25. A displacement prevention member (not shown) made of a rubber pad or the like for preventing displacement of a 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 section 3 has an opening 3c that allows the massage section 4 to protrude more toward the body part than the movable support section 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. Accordingly, when the foot is placed on the movable support portion 3, the toe contacts the step 3a in front of the opening 3c, and the heel contacts the step 3a behind the opening 3c. It can be stably supported.

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

  The mechanism section 7 has a drive shaft 8 whose axial direction is the left-right direction rotated by the drive of the motor 6. The drive shaft 8 is rotatably supported by a bearing 20 provided on the lower member 2 a on the rear side of the base 2. Further, eccentric shafts 21 eccentric to the axis 8 a of the drive shaft 8 are provided at both left and right end portions of the drive shaft 8. The phases of the left and right eccentric shafts 21 around the axis 8a of the drive shaft 8 are different from each other, 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 3. That is, the crank mechanism 9 is constituted by the eccentric shaft 21 and the arm 23. The left arm 23 is connected to the left movable support 3, and the right arm 23 is connected to the right movable support 3. The movable support portion 3 is rotatably connected to the arm 23 via a pivot 24.

  In addition, the mechanism section 7 has a guide section 10 that converts the rotation of the drive shaft 8 into the forward and backward movement of the movable support section 3. The guide part 10 has a guide shaft 25 whose axial direction is the left-right direction. The guide shaft 25 is provided on the bearing 26 provided on the lower member 2a so as to be rotatable at a front part of the base 2 in the front-rear direction with respect to the drive shaft 8. The base 2 and the movable support 3 are connected via a guide shaft 25. The movable support 3 is provided rotatably on the guide shaft 25.

  The mechanism section 7 has a speed reducer 11 that reduces the driving force of the motor 6 and transmits the reduced driving force to the drive shaft 8 and the guide shaft 25. The speed reducer 11 includes a first pulley 31 provided at an intermediate portion in the axial direction of the drive shaft 8, a first belt 32 connecting the output shaft 6 a of the motor 6 and the first pulley 31, and an axial intermediate portion of the guide shaft 25. A second pulley 33 provided in the section and a second belt 34 connecting the drive shaft 8 and the second pulley 33 are provided. Accordingly, the driving force of the motor 6 is transmitted to the drive shaft 8 at a reduced speed, and further transmitted to the guide shaft 25 at a further reduced speed than the rotation speed of the drive shaft 8. That is, the rotation speed of the drive shaft 8 is higher 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 section 4 is a roller 40 provided on the guide shaft 25. The roller 40 can rotate integrally with the guide shaft 25 about the axis of the guide shaft 25. A plurality (two in the present embodiment) of the rollers 40 are provided in the left-right direction, and are respectively positioned corresponding to the left and right feet. The roller 40 has a plurality of treatment elements 40 a having protrusions, and a holding portion 40 b attached to the guide shaft 25 and holding the treatment element 40 a. The holding portions 40b are paired at predetermined intervals in the left-right direction, and the treatment element 40a is held between the paired holding portions 40b, 40b so as to be rotatable around the left-right axis. A plurality of (three in this embodiment) treatment elements 40a are provided in the circumferential direction of the guide shaft 25.

  The roller 40 is mostly located below the movable support portion 3 and is located at a position corresponding to the opening 3c. The roller 40 at least partially protrudes from the opening 3 c toward the body part side with respect to the movable support 3. When the movable support 3 is moving forward and backward, the roller 40 does not always need to protrude toward the body part side than the movable support 3, and a part of the roller 40 is closer to the body part than the movable support 3. It suffices if even a little protruding state occurs.

  When the guide shaft 25 rotates, the massager 40a periodically imparts a massage action to the body part of the roller 40 configured as described above. 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, with the rotation of the guide shaft 25, the amount of advance of the roller 40 as a whole toward the body part 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 facing in the left-right direction, and a massage effect may be given such that a 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 driving force of the motor 6 is transmitted by the mechanism unit 7, so that the guide shaft 25 also rotates. As the drive shaft 8 rotates, the rotation of the arm 23 connecting the eccentric shaft 21 and the movable support 3 is regulated by the guide shaft 25, so that the arm 23 orbits around the axis 8 a of the drive shaft 8. Therefore, the connecting portion 3b, which is the rear portion of the movable support portion 3, performs a vertical motion having a slight front and rear component. That is, when viewed as a whole of the movable support portion 3, as shown in FIG. 4, the front side performs a rocking motion in which the front side moves up and down along the arrow a as the fulcrum. Since the left and right eccentric shafts 21 are 180 degrees out of phase with each other about the axis 8a of the drive shaft 8, the pair of movable support portions 3 swing 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 foot supported by the movable support portion 3 moves up and down on the toe side with the heel side as a fulcrum. The directions in which the left and right legs move are opposite directions. If the rotation of the motor 6 is accelerated and the movable support portion 3 is quickly swung, a motion of vibrating the lower limbs can be performed, and the muscles of the ankles and calves can be relaxed. If the rotation of the motor 6 is slowed down and the movable support 3 is slowly swung, the exercise of stretching the muscle of the Achilles tendon can be performed.

  Further, it is preferable that the movable support portion 3 is provided so as to be inclined so that the front side is located closer to the body part (upper side) than the rear side in a state where the front side in the advance / retreat range is most retracted (down). With this configuration, it is possible to cause the body part to exercise sufficiently without increasing the range of movement of the movable support unit 3. For example, when the foot is placed on the movable support part 3 and used, the toes can be further raised from the raised state, so that the ankle can be bent sufficiently.

  Alternatively, the movable support section 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 in the state where the front side in the advance / retreat range is most advanced (up). With such a configuration, a sufficient exercise can be performed on the body part without increasing the range of movement of the movable support portion 3. For example, when the foot is placed on the movable support portion 3 and used, the toe can be further lowered from the lowered state, so that the ankle can be sufficiently bent.

  Note that control means (not shown) having a microcomputer may be provided to automatically change the rotation speed and the 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 exercised. Further, the roller 40 can give a massage action to the arch. In this way, exercise and massage can be performed on the lower limb, which is a body part, in a combined manner.

[Example of using 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 a floor and used while sitting on a chair. In this case, the left and right feet are mounted on the pair of movable support portions 3 with the knee bent at approximately 90 degrees. Further, the massage machine 1 can be placed on the floor and used in an upright state. In this case, the left and right feet are placed on the pair of movable support portions 3 with the knees extended, respectively. Also, 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 knee extended. Further, the massage machine 1 can be placed on a floor or a seat 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 supports 3. That is, the left buttocks are placed on the left movable support 3 and the right buttocks are placed on the left movable support 3 for use.

It shows a state rotated by degrees. 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 3 moves forward and backward without changing the angle with respect to the floor surface in step 3a. Hereinafter, the same components as those of the massage machine 1 are denoted by the same reference numerals, and the description thereof will be omitted.

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

  The base 2 includes a drive shaft 8 whose axial direction is a left-right direction rotated by the drive of the motor 6, a driven shaft 51 whose left-right direction rotates in conjunction with the rotation of the drive shaft 8, and a massage unit 4. And a rotation shaft 52 having a left-right direction as an axial direction for rotatably supporting the rotation shaft 52. 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 rotation shaft 52, and when the drive shaft 8 or the driven shaft 51 rotates, the rotation shaft 52 also rotates. 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 in the front-rear direction of the movable support portion 3 are connected by a crank mechanism 9. The driven shaft 51 and the other end 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 configuration as the crank mechanism 9 of the massage machine 1. Further, a guide portion 55 for converting the rotation of the drive shaft 8 into the forward and backward movement 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 portion 55 is constituted by the guide groove 56 and the connecting portion 3b. As described above, the mechanism unit 70 includes the drive shaft 8, the driven shaft 51, the rotation 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 70, so that the driven shaft 51 and the rotary shaft 52 also rotate. When the drive shaft 8 rotates, the rotation of the arm 23 connecting the eccentric shaft 21 and the movable support portion 3 is regulated by the guide portion 55, so that the arms 23 respectively orbit the drive shaft 8 and the driven shaft 51. . Therefore, the movable support unit 3 moves up and down along the arrow b without changing the angle of the step 3a with respect to the floor surface. 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, Modification 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 a base 2 according to a second modification of the present invention is omitted. FIG. 11 is a plan view of a massage machine 200 in which a part of the base 2 according to a second modification 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 second modification of the present invention is omitted.
The difference from the above-described massage machine 1 is that the movable support portion 3 is connected to the base 2 at both ends in the front-rear direction. Hereinafter, the same components as those of the massage machine 1 are denoted by the same reference numerals, and the description thereof will be omitted.

  Similar to the above-described massage machine 1, the massage machine 200 mainly includes a base 2 placed on the floor, a movable support portion 3 for supporting a body part (foot) that is a part of the body of the user, and a movable support portion. It has a massage part 4 for massaging a body part (foot) supported by the part 3, and a drive mechanism 5 for driving the movable support part 3 and the massage part 4. The drive mechanism 5 has a motor 6 and a mechanism section 80 that transmits the driving force of the motor 6 to the movable support section 3 and the massage section 4. The mechanism unit 80 includes a drive shaft 8, a crank mechanism 9, a guide unit 60 (guide shaft 61), a rotation shaft 62, and the speed reducer 11, which will be described later in detail.

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

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

  The mechanism section 80 includes the speed reducer 11 that reduces the driving force of the motor 6 and transmits the reduced driving force to the drive shaft 8 and the rotating shaft 62. The speed reducer 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 axial halfway of the rotary shaft 62. A second pulley 33 provided in the section and a second belt 34 connecting the drive shaft 8 and the second pulley 33 are provided. Accordingly, the driving force of the motor 6 is transmitted to the drive shaft 8 at a reduced speed, and further transmitted to the rotation shaft 62 at a further reduced speed than the rotation speed of the drive shaft 8. 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 rotation shaft 62 whose axial direction is the left-right direction. The roller 40 is rotatable around the axis of the rotation shaft 62. A plurality (two in the present embodiment) of the rollers 40 are provided in the left-right direction, and are respectively positioned corresponding to the left and right feet. As shown in FIGS. 6 and 7, the roller 40 includes a plurality of treatment elements 40 a having protrusions, and a holding portion 40 b attached to the rotating shaft 62 and holding the treatment element 40 a. I have. The holding portions 40b are paired at predetermined intervals in the left-right direction, and the treatment element 40a is held between the paired holding portions 40b, 40b so as to be rotatable around the left-right axis. A plurality of treatment elements 40a (three in this embodiment) are provided in the circumferential direction of the rotation shaft. When the rotation shaft 62 rotates, the massager 40a periodically applies a massage action to the body part of the roller 40 configured as described above.

  In the massage machine 200 configured as described above, when the motor 6 is driven, the driving shaft 8 rotates, and the driving force of the motor 6 is transmitted by the mechanism unit 80, so that the rotating shaft 62 also rotates. When the drive shaft 8 rotates, the rotation of the arm 23 connecting the eccentric shaft 21 and the movable support portion 3 is restricted by the guide shaft 61, so that the arm 23 orbits around the axis 8 a of the drive shaft 8. Therefore, the connecting portion 3b, which is the rear portion of the movable support portion 3, performs a vertical motion having a slight front and rear component. That is, when viewed as a whole of the movable support portion 3, as shown in FIG. 12, the swing 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 left and right eccentric shafts 21 are 180 degrees out of phase with each other about the axis 8a of the drive shaft 8, the pair of movable support portions 3 swing in opposite directions. The roller 40 rotates around the axis of the rotation shaft 62.

  According to the massage machine 200 that operates as described above, the heel side of the foot supported by the movable support portion 3 moves up and down with the toe side as a fulcrum. The directions in which the left and right legs move are opposite directions. If the rotation of the motor 6 is accelerated and the movable support portion 3 is quickly swung, a motion of vibrating the lower limbs can be performed, and the muscles of the ankles and calves can be relaxed. If the rotation of the motor 6 is slowed down and the movable support 3 is slowly swung, the exercise of stretching the muscle of the Achilles tendon can be performed. Moreover, since the movable support 3 is connected to the base 2 at both front and rear ends, the movable support 3 can be operated stably. In addition, abnormal noise can be reduced, and the durability of the massage machine 200 also improves.
