First, the massage device 5 will be described using Figs. 1 to 12C.

The massage device 5 has massage members 12 and 13 that are provided in a pair of upper and lower sides, and a massage mechanism 15 that operates the pair of massage members.

In addition, the following description relates to one member and the other member of the massage members 12 and 13 that are provided in pairs, one of which is referred to as the massage member 13, and the other member is referred to as the massage member 12. Of course, the upper massaging member 12 is positioned above the lower massaging member 13.

The upper massage member 12 and the lower massage member 13 are combined to constitute a massage body 14. The massage body 14 is provided with one (pair) in each of the left and right directions.

The upper massaging member 12 constituting the massaging body 14 has an arm-shaped upper arm 20 that protrudes obliquely forward toward the upper side, and an upper applicator 21 that is provided at the upper end portion of the upper arm 20. And, the lower massage member 13 has a downward facing formation The arm-shaped lower arm 22 that protrudes obliquely forward in the side, and the lower applicator 23 that is provided at the lower end portion of the lower arm 22. The upper therapeutic device 21 and the lower therapeutic device 23 are, for example, a disk shape or a spherical shape formed of a resin or a hard rubber or the like.

The base end portion (the lower end portion) of the upper arm 20 of the upper massage member 12 and the proximal end portion (the upper end portion) of the lower arm 22 of the lower massage member 13 are disposed to overlap each other in the left-right direction to constitute a massage. Body 14. In other words, the upper massage member 12 and the lower massage member 13 are in a state in which their base end portions are adjacent to each other, and the front end portions (the upper therapeutic device 21 and the lower therapeutic device 23) are disposed to be vertically separated.

The massage body 14 configured as described above is provided on the front side of the plate-shaped bottom member 16 in a pair of left and right sides, and the bottom member 16 has a massage mechanism 15 that drives the pair of right and left massage bodies 14, 14 in detail to make the massage belt 14 The massage mechanism 15 that reciprocates in at least one of the upper massage member 12 and the lower massage member 13 in the vertical direction.

As shown in FIGS. 2 and 3, the massage mechanism 15 has a kneading drive unit 24 that generates a kneading motion in the massage body 14, and a tap drive unit 25 that generates a tapping motion on the massage body 14.

The kneading drive unit 24 is a kneading action (hereinafter referred to as "clamping kneading") in which the upper applicator 21 and the lower applicator 23 are separated from each other, and a pair of right and left massage bodies 14 and 14 are formed in each of the massaging bodies 14. The kneading action (hereinafter referred to as "pushing kneading") is performed by approaching each other in the left-right direction.

Specifically, the "holding and kneading" is to alternately impart a downward movement and an upward movement between the upper urging means 21 of the upper massage member 12 and the lower urging means 23 of the lower massage member 13, or alternately imparting forward and backward movements. Place The resulting massage action. The upper applicator 21 of the upper and lower upper massage members 12 are alternately given to each other to be separated from each other, or the applicators 23 of the left and right lower massage members 13 are alternated with each other. Give each other a massage action that is close to each other.

On the other hand, the striking driving unit 25 of the massaging mechanism 15 causes the pair of right and left massage bodies 14 and 14 to cooperate to perform the forward and backward projection and retreat operations, or to generate a tapping motion to the user. Specifically, the tap driving unit 25 is the upper massage device 21 of the upper massage member 12 and the upper massage member 14 (the right massage body 14) of the upper massage member 12 in the left massage body 14 (left massage body 14). The upper and lower swings of the small distance are simultaneously or alternately performed between the upper therapeutic devices 21. Similarly, the striking drive unit 25 performs simultaneous or alternate back and forth swing between the lower applicator 23 of the lower massaging member 13 in the left massaging body 14 and the lower applicator 23 of the lower massaging member 13 in the right massaging body 14.

Next, a specific configuration of the kneading drive unit 24 will be described.

4A to 11th, the kneading drive unit 24 includes a coaxial hub portion 26 provided at an arm base end portion of one massage member among the pair of upper and lower massage members 12 and 13; An eccentric hub portion 27 of the arm base end portion of the member; the first center shaft 28 that extends through the coaxial hub portion 26 and the eccentric hub portion 27 in the axial direction; and a kneading motor that rotationally drives the first shaft 28 29.

Further, the kneading drive unit 24 includes a base end portion provided in one of the pair of upper and lower massage members 12 and 13, and restricts rotation of the pair of upper and lower massage members 12 and 13 without the rotation of the first rotating shaft 28 Stop mechanism 30; and each other disposed on the upper and lower pair of massage members 12, 13 In the meantime, the interlocking rotation mechanism 31 that rotates the pair of upper and lower massage members 12 and 13 in the same direction around the first rotating shaft 28 is held.

In the present embodiment, the eccentric hub portion 27 is provided to the proximal end portion of the upper arm 20 of the upper massaging member 12, and the base end portion of the lower arm 22 of the lower massaging member 13 is provided in the pair of upper and lower massage members 12 and 13. Coaxial hub portion 26. Further, in the present embodiment, among the pair of upper and lower massage members 12 and 13, the rotation stop mechanism 30 is provided to the proximal end portion of the lower arm 22 of the lower massage member 13.

As shown in FIGS. 9 to 11 , the coaxial boss portion 26 is formed as a disk-shaped member having a peripheral surface having a constant width, and a central portion of the circular shape is formed in a non-parallel (inclined) direction with respect to the outer peripheral surface. Shaft hole. Therefore, the coaxial boss portion 26 is set to pass the first rotating shaft 28 through the center portion thereof, and the coaxial boss portion 26 is provided to be integrally rotatable in a state of being inclined with respect to the first rotating shaft 28.

A bearing holder 33 such as a bearing is fitted around the coaxial hub portion 26 (peripheral surface), and the lower arm 22 of the lower massage member 13 is fitted and fitted through the bearing holder 33. Therefore, the state in which the lower arm 22 is freely rotatable with respect to the first rotating shaft 28 is maintained.

The eccentric hub portion 27 is formed in a disc shape having a constant width peripheral surface that is substantially the same width as the outer peripheral surface of the coaxial boss portion 26, and is formed in a non-parallel portion of the circular non-central portion (eccentric position) so as to be non-parallel with respect to the outer peripheral surface. Axial hole in the (tilt) direction. Therefore, the eccentric hub portion 27 is set to pass the first rotating shaft 28 through the non-center portion thereof, and the eccentric hub portion 27 is provided to be integrally rotatable in a state of being inclined with respect to the first rotating shaft 28. Furthermore, the eccentric hub The "non-center portion" in the portion 27 is a position that is displaced from the "center portion" of the eccentric hub portion 27 in the radial direction.

A bearing holder 34 such as a bearing is fitted to the outer peripheral surface of the eccentric hub portion 27, and the upper arm 20 of the upper massaging member 12 is provided through the bearing holder 34. Therefore, the state in which the upper arm 20 is freely rotatable with respect to the first rotating shaft 28 is maintained.

As described above, the base end portion of the upper arm 20 of the upper massaging member 12 and the base end portion of the lower arm 22 of the lower massaging member 13 are disposed to overlap each other in the left-right direction, so that the coaxial hub portion 26 and the eccentric hub portion 27 are formed along the same The axial center of the first rotating shaft 28 is adjacent and close to each other. Further, as shown in Fig. 6, the coaxial boss portion 26 and the eccentric hub portion 27 are integrally formed by a partition portion 35 which is thinner than the hub.

The spacer 35 has a constant thickness in the peripheral direction, and is provided such that the eccentric hub portion 27 is inclined with respect to the first rotating shaft 28 in the same direction as the coaxial boss portion 26. That is, the coaxial hub portion 26 and the eccentric hub portion 27 are disposed on the first rotating shaft 28 in a direction parallel to each other (inclination in the same direction). Further, "parallel" is not only a strictly parallel state but also includes a case where the inclination of the coaxial hub portion 26 and the eccentric hub portion 27 is slightly inferior.

Further, as shown in Fig. 9, in the present embodiment, the inclination directions of the coaxial hubs 26 and the eccentric hubs 27 between the left and right massage bodies 14 and 14 are maintained at a phase difference of 180° around the first rotating shaft 28. In other words, as shown in Fig. 9, in the first rotating shaft 28 in the horizontal direction, the upper interval between the right and left coaxial boss portions 26 (between the eccentric hub portions 27) is the narrowest, and the lower interval is the widest. However, the left and right coaxial hub portions The phase difference (positional relationship) between the 26 (the eccentric hub portions 27) and the phase difference between the coaxial hub portion 26 and the eccentric hub portion 27 can be appropriately changed to realize the desired upper massage member 12 and lower massage member 13 Actions.

In the present embodiment, the upper massage member 12 (the coaxial hub portion 26) is disposed outside the left and right direction between the left and right massage bodies 14 and 14, and the lower massage member 13 (the eccentric hub portion 27) is positioned in the left-right direction. Inside. However, the lower massage member 13 (the eccentric hub portion 27) may be provided on the outer side in the left-right direction, and the upper massage member 12 (the coaxial hub portion 26) may be formed on the inner side in the left-right direction.

As shown in FIG. 3, the kneading motor 29 is coupled to the right end portion of the first rotating shaft 28 via the speed reducing portion 36. Therefore, by driving the kneading motor 29 to rotate the first rotating shaft 28, the coaxial boss portion 26 and the eccentric hub portion 27 can be integrally rotated.

At this time, the coaxial hub portion 26 is swung and rotated in the left-right direction with the rotation center of the first rotating shaft 28 as an axis, and the rotation is transmitted to the lower therapeutic device 23 through the lower arm 22 . Further, the eccentric hub portion 27 swings and rotates in the left-right direction with the rotation center of the first rotating shaft 28 as an axis, and also causes eccentricity in the radial direction during one rotation of the eccentric hub portion 27. The operation of the eccentric hub portion 27 is transmitted to the upper therapeutic device 21 through the upper arm 20.

As shown in FIG. 4B and FIG. 5, the rotation stopping mechanism 30 is for causing the upper massaging member 12 and the lower massaging member 13 not to rotate with the first rotating shaft 28, specifically, the lower arm 22 of the lower massaging member 13. The base end has, for example, a structure of an elbow joint such as a snap ball joint or a universal joint to make. The rotation stop mechanism 30 transmits the connection relationship with the second rotating shaft 45 of the tapping drive unit 25 through the link 58 of the tap driving unit 25 to be described later.

In other words, when the first rotating shaft 28 rotates, even if the lower massage member 13 is rotated by the rotation, the lower arm 22 of the lower massaging member 13 is kept in a state of not rotating together with the first rotating shaft 28 by the rotation stopping mechanism 30. . However, when the rotation stop mechanism 30 employs the elbow joint, the operation in the predetermined range along the front-rear direction, the left-right direction, and the up-and-down direction is allowed.

As shown in FIG. 4B and FIG. 5, the interlocking rotation mechanism 31 holds the upper massage member 12 and the lower massage member 13 in the same direction around the first rotating shaft 28. The interlocking rotation mechanism 31 is provided with a pin member 37 that protrudes toward the proximal end portion of the lower arm 22 of the adjacent lower massaging member 13 at the proximal end portion of the upper arm 20 of the upper massaging member 12, and a lower arm of the lower massaging member 13 The base end portion of the 22 is configured to be fitted into the sliding groove 38 of the pin member 37.

Specifically, as shown in FIG. 5, the pin member 37 is on the opposite side of the upper massage member 12 (the side opposite to the lower massage member 13), and the first rotating shaft 28 is placed on the opposite side of the upper therapeutic device 21. The pin member 37 protrudes toward the lower massage member 13 on the opposite side of the upper massage member 12.

The slide groove 38 is provided on the opposite side of the lower massaging member 13 (the side opposite to the upper massaging member 12), and is disposed between the applicator 23 on the lower side and the first rotating shaft 28 in the vertical direction. The upper massage member 12 and the lower massage member 13 are provided to overlap the base end portions, and the pin member 37 is fitted into the sliding groove 38.

The pin member 37 is slidably moved in the sliding groove 38, and can be restricted The upper and lower separation movements of the upper massage member 12 and the lower massage member 13 allow for a large rotation of the upper massage members 12 to each other.

That is, when the first rotating shaft 31 rotates, even when the first rotating shaft 28 is rotated, the upper massage member 12 or the lower massage member 13 is about to rotate, and the pin member 37 is freely inserted into the sliding groove 38. The sliding is guided so that the accompanying rotation of the upper massaging member 12 and the lower massaging member 13 can be maintained.

As described above, the left and right massage bodies 14 and 14 in the kneading drive unit 24 cause the upper therapeutic devices 21 of the upper massage member 12 to be close to each other in the left-right direction and separated from each other to perform the "pushing and kneading" operation. Similarly, the lower applicator 23 of the lower massage member 13 is moved closer to each other in the left-right direction and separated from each other to perform the "push-kneading" operation. Further, when the upper therapeutic devices 21 are brought close to each other, the lower therapeutic devices 23 are separated from each other, and the upper therapeutic devices 21 are mutually adjacent to each other.

Further, in addition to the above-mentioned "pushing near kneading", the upper applicator 21 of the upper massage member 12 is alternately repeatedly pushed forward in the longitudinal direction of the corresponding eccentric hub portion 27 (Figs. 12A to 12C, L1>L2>L3) or by downward movement (H1>H2>H3 in FIG. 12A to FIG. 12C), the approach of the lower massage member 13 toward the lower applicator 23, and the short radial direction of the corresponding eccentric hub portion 27 Rear retreat (in FIG. 12A to FIG. 12C, L3>L2>L1) or by upper movement (in FIG. 12A to FIG. 12C, H3>H2>H1) such that the lower massage member 13 faces the lower therapeutic device 23 Separation.

The lower applicator 23 of the lower massage member 13 is not the eccentric hub portion 27 Since the coaxial hub portion 26 is provided, the upward movement or the downward movement by the upper treatment device 21 of the massage member 12 is hardly performed. As a result, the upper urging device 21 of the upper massage member 12 repeats the operation of the lower urging device 23 of the massage member 13 to close and separate from each other, thereby causing "clamping and kneading".

Next, a specific configuration of the above-described tapping drive unit 25 will be described.

As shown in FIG. 1 to FIG. 4B, the tapping drive unit 25 has a second rotating shaft 45, and is disposed at a position higher than the first rotating shaft 28 so that the axial center is parallel to the left-right direction; the knocking motor 47 is rotationally driven. The second rotating shaft 45; the left and right eccentric driving bodies 53 are eccentrically disposed at the left and right end portions of the second rotating shaft 45 with a phase difference of 180° around the axial center; and the connecting rod 58 (long-sized crankshaft) is freely movable The casing 54 that rotatably holds the right and left eccentric driving bodies 53 protrudes downward.

The eccentric drive body 53 is provided with a eccentric collar on its inner ring side or outer ring side as a bearing, whereby the second rotating shaft 45 is not aligned with the axial center of the casing 54. The lower end portion of the link 58 is connected to the proximal end portion of the lower arm 22 of the lower massaging member 13, but the connecting portion is formed by the above-described rotation stopping mechanism 30 (ball joint or the like). That is, the lower end portion of the link 58 is provided with a rotation stop mechanism 30, and the base end portion of the lower arm 22 of the lower massage member 13 is coupled to the rotation stop mechanism 30.

Therefore, when the tapping drive unit 25 drives the knock motor 47, the eccentric drive body 53 is eccentrically rotated with respect to the axial center of the second rotating shaft 45, and this rotation is received to move the casing 54 circumferentially. Therefore, going up and down from the housing 54 The push-pull action of the direction is transmitted to the link 58 (long-sized crankshaft). According to the above, the left and right massage bodies 14, 14 cause the upper therapeutic devices 21 of the upper massage member 12 to swing around each other at a small distance around the first rotating shaft 28, so that the upper therapeutic device 21 and the lower therapeutic device 23 are opposite in the front-rear direction. The movement of the direction, so this produces a tapping action as the massage body 14.

Further, since the swings generated by the left and right massage bodies 14 and 14 are eccentric drive bodies 53 provided around the second rotation shaft 45 with a phase difference of 180°, they are alternately generated. That is, when the massage body 14 on the left side moves the upper treatment device 21 forward, the massage body 14 on the right side moves the upper treatment device 21 rearward. Conversely, when the massage body 14 on the left side moves the lower therapeutic device 23 forward, the massage body 14 on the right side moves the lower therapeutic device 23 rearward.

However, this is not a limitation. For example, an appropriate switching mechanism for setting the phase difference to the right and left eccentric driving bodies 53 is set in advance, and the setting of the tapping operation (tapping mode) can be changed to make the left and right massage. The bodies 14, 14 are synchronized to oscillate in the same direction.

The vertical movement mechanism 10 for moving the massaging device 5 configured as described above has a pair of right and left guide rails 46 which are provided inside the backrest portion 3 and are capable of freely moving up and down the bottom member 16 of the guiding massage device 5; The screw shaft 52 between the two guide rails 46 and the lift motor 57 that rotationally drives the screw shaft 52 are formed.
