A massaging mechanism 3 for massaging the treatment portion is disposed on the center side of the support frame 4 formed in a rectangular frame shape by the main frame 4M and the sub frame 4S described above.

The massaging mechanism 3 includes a base 9 elongated in the left-right direction, and a mechanism for performing a massaging operation is attached to the base 9. The left and right ends of the massaging mechanism 3 are connected to the support frame 4 (main frame 4M) described above via a moving mechanism 10 described later, and are movable in the front-rear direction with respect to the support frame 4.
Specifically, the massaging mechanism 3 has one drive motor 11 disposed with the drive shaft 11 a facing in the left-right direction on the base 9 described above, and an axis turning in the left-right direction by the drive motor 11. The rotary shaft 12 is rotationally driven, and the massaging body 13 which swings in the left and right direction by the rotational driving force of the rotary shaft 12 and performs massage on the buttocks (treatment part). Moreover, the treatment element 14 which massages (treatment) the treatment part of the user U is provided in the front end side of the massaging body 13 mentioned above. That is, the massage mechanism 3 according to the present embodiment enables the massage (massaging massage) to the treatment unit by swinging the massaging body 13 to the left and right while pressing the treatment element 14 against the treatment unit of the seated user U. .

In addition, although the massage mechanism 3 of this embodiment performs itching massage with respect to a treatment part, what performs a hit massage with respect to a treatment part as a massage mechanism 3 of this invention, what performs a grip massage etc. Or a combination of these massages may be used.
Next, respective members such as the drive motor 11, the rotating shaft 12, the massaging body 13 and the treatment element 14 constituting the massaging mechanism 3 of the present embodiment will be described.

The treatment unit in which the massage is performed by the above-described massage mechanism 3 includes at least the buttocks of the body of the user U. A thigh, a waist, etc. can be included in a treatment part as treatment parts other than the buttocks. That is, the massage device 1 of the present embodiment is configured to treat the wide lower leg from the waist to the thigh as the treatment section, centering on the buttocks.
As shown in FIG. 3, the drive motor 11 is disposed on the center side of the base 9 of the massaging mechanism 3 in the left-right direction, and the drive shaft is disposed in a direction along the left-right direction. In the case of the massage mechanism 3 of the present embodiment, the drive motor 11 is disposed substantially at the center of the massage mechanism 3 in the left-right direction, and attached so as to extend the drive shaft 11a from the center to the left. . A first worm gear 15 is provided on the drive shaft 11 a of the drive motor 11 so as to be integrally rotatable with the drive shaft 11 a.

The first worm gear 15 of the drive shaft 11a is a first worm wheel 17 mounted on the rear end side of the power transmission shaft 16 disposed along a direction (longitudinal direction) orthogonal to the drive shaft 11a. The rotational driving force of the drive shaft 11 a is transmitted to the power transmission shaft 16. The power transmission shaft 16 also has a second worm gear 18 on the front end side located at the end opposite to the rear end side where the first worm wheel 17 is provided in the longitudinal direction. The second worm gear 18 of the power transmission shaft 16 meshes with the second worm wheel 19 of the rotary shaft 12 described above, and the rotational drive force of the drive shaft 11 a of the drive motor 11 has two worm mechanisms and the power transmission shaft 16. And is transmitted to the rotating shaft 12 via the. In this manner, the rotary shaft 12 is rotationally driven about an axis directed in the left-right direction by the rotational drive force generated by the drive motor 11.

The rotating shaft 12 converts the rotational movement of the rotating shaft 12 into translational movement (rocking movement) of the massaging body 13 along the lateral direction on the left end side and the right end side of the second worm wheel 19 described above. Each one.
The conversion unit 20 is attached so as to rotate integrally with the rotary shaft 12 and has a boss portion 21 on the outer peripheral side with a cam surface circling about an axis facing a direction inclined with respect to the axial center of the rotary shaft 12 And the annular fitting portion 22 provided at the base end of the massaging body 13 and fitted into the cam surface of the boss portion 21 and the massaging body 13 rotating with the rotation of the rotary shaft 12 (massage body 13 And the regulation unit 23 that regulates the turnaround). Specifically, the annular fitting portion 22 is slidably fitted on the cam surface of the boss portion 21 via a bearing. The annular fitting portion 22 is formed on the base end side (lower end side) of the massaging body 13 and is formed in a ring shape in side view. The annular fitting portion 22 is externally fitted to a bearing fitted on the cam surface of the boss portion 21, so that the rotational movement of the rotary shaft 12 is a translational movement (rocking movement) along the right and left direction of the massaging body 13. It is to convert. Therefore, the boss portion 21 and the annular fitting portion 22 are rotatable relative to each other.

In addition, the restricting portion 23 is attached at a position where it can be in contact with the restricting projection 24 on the base 9 and the restricting projection 24 provided in the shape of a rib projecting downward on the proximal end side of the massaging body 13. And a detent member 25 that regulates the rotation of the massaging body 13. The restricting projections 24 are formed on each of the massaging body 13 extending forward from the rotating shaft 12 and the massaging body 13 extending rearward, and the detent member 25 contacts both the restricting projections 24 on the front side and the rear side. It is attached to the front and back of the rotating shaft 12 on the base 9 as possible.

That is, the regulating portion 23 regulates the accompanying rotation of the massaging body 13 around the rotation shaft 12 by bringing the regulating projection 24 of the massaging body 13 into contact with the detent member 25 mounted on the base 9. And the massaging body 13 is translated (rocking) in the lateral direction.
The massaging body 13 is a rod-like member extending forward and backward slightly and rearward and slightly upward from a proximal end side provided with an annular fitting portion 22 externally fitted to the cam surface of the boss portion 21 through a bearing. At the front end and the rear end of the massaging body 13, a treatment element 14 for massaging the treatment section is provided. That is, the massage apparatus 1 of this embodiment is equipped with the "four ball system" massage mechanism 3 provided with the four treatment elements 14.

By the way, the massage apparatus 1 of this invention is equipped with the moving mechanism 10 which can move the massage mechanism 3 in the front-back direction with respect to the support frame 4. As shown in FIG. The moving mechanism 10 is disposed on the left and right sides of the massage mechanism 3 along the guide rail portion 6 provided along the front-rear direction on the main frame 4M of the support frame 4 described above, and travels on the guide rail portion 6 described above And the pinion gear 26 made possible.

The guide rail portion 6 is a rail member for guiding the massage mechanism 3 in the front-rear direction, and is attached along the lower opening edge of the pocket portion 5 of the main frame 4M described above. A plurality of rack teeth capable of meshing with the pinion gear 26 are formed on the upper surface of the guide rail portion 6.
The pinion gear 26 is a gear capable of traveling on the guide rail portion 6 by meshing with the rack teeth of the guide rail portion 6 described above, and is rotatably attached to both end sides of the rotary shaft 12. The rotational driving force of the rotary shaft 12 is transmitted to the pinion gear 26 in a decelerating state by using a transmission mechanism 27. That is, the pinion gears 26 are provided at both ends of the rotary shaft 12 and are configured to rotate around an axis facing in the left-right direction at a rotational speed different from that of the rotary shaft 12.

As shown in FIG. 3 and FIG. 4, the transmission mechanism 27 can transmit the rotational driving force of the rotary shaft 12 to the pinion gear 26 in a state of being shifted. Specifically, the transmission mechanism 27 has a first gear 28, a driven shaft 29, a second gear 30, a third gear 31, and the like.
That is, the transmission mechanism 27 is provided with the first gear 28 on the left and right ends of the rotary shaft 12. The first gear 28 of the rotating shaft 12 meshes with the second gear 30 of the driven shaft 29 disposed parallel to the front of the rotating shaft 12, and the rotational driving force of the rotating shaft 12 is decelerated to the driven shaft 29. I am communicating. A third gear 31 is provided on the opposite side of the driven shaft 29 to the second gear 30. The third gear 31 transmits the driving force in a decelerating state to the pinion gear 26 disposed outside the width direction of the first gear 28 described above. Therefore, while the pinion gear 26 described above is mounted coaxially with the rotary shaft 12, it rotates at a rotational speed (a low rotational speed) different from that of the rotary shaft 12.

That is, in the moving mechanism 10 described above, the pinion gear 26 to which the rotational driving force of the rotating shaft 12 is transmitted is rotated by the above-described transmission mechanism 27 and the pinion gear 26 travels on the guide rail portion 6 meshed with the pinion gear 26. The massage mechanism 3 can move in the front-rear direction along the guide rail portion 6.
By the way, in the massage device 1 of the present invention, the front end side of the guide rail portion 6 is curved so as to hang down toward the front with respect to the rear end side. It is characterized in that it can be accommodated.

Specifically, on the front end side of the guide rail portion 6, a hanging portion 32 which curves so as to hang downward toward the front is provided. As shown in FIG. 5, when the length “l” of the hanging portion 32 along the front-rear direction is “l ₀ ”, the total length of the guide rail 6 in the front-rear direction is “rear” from the front end of the guide rail 6 It is a range of about 10% of "l ₀ " toward the end side.
Further, in FIG. 5, when the overall length along the front-rear direction of the device body 2 is “L ₀ ”, the position “L” where the hanging portion 32 is provided is “L ₀ ” from the front end of the device body 2 It is considered to be around 30%. By providing the hanging portion 32 at such a position, it is possible to reliably massage the treatment portion of the user U including at least the buttocks, and to reliably store the massage mechanism 3.

Furthermore, as shown in FIG. 5, when the thickness along the vertical direction of the device main body 2 is “T ₀ ”, the drooping amount “T” of the hanging portion 32 is at least about half of the outer diameter of the treatment element 14. The maximum width is the same as the outer diameter of the treatment element 14.
If the drooping portion 32 is formed to such a sagging amount, the massaging mechanism 3 can be moved so as to sink downward, and the massaging mechanism 3 can be reliably housed inside the massaging device 1.

For example, when the pinion gear 26 is located on the guide rail portion 6 on the rear side of the hanging portion 32, the massaging mechanism 3 is slightly protruded upward. That is, the upper half of the treatment element 14 protrudes upward from the upper surface of the apparatus main body 2 so that the massaging mechanism 3 can massage the treatment section. Therefore, in order to enable the massage by the treatment element 14, the guide rail portion 6 on the rear side of the hanging portion 32 is also held at a high position.

However, when stopping the massaging operation of the massaging mechanism 3 and housing the massaging mechanism 3 in the apparatus main body 2, the height of the guide rail portion 6 is reduced by the amount of protrusion of the treatment element 14, in other words, of the hanging portion 32. The drooping width needs to be a width corresponding to the protrusion of the treatment element 14. That is, since the height at which the treatment element 14 protrudes from the upper surface of the device main body 2 when performing the massage is about half of the outer diameter of the treatment element 14 to approximately the radius, the outside of the treatment element 14 is described above. The massaging mechanism 3 can be reliably housed inside the massaging device 1 by forming the hanging portion 32 with a hanging width of half or more of the diameter.

Therefore, in the massage device 1 of the present invention, there is no concern that the treatment element 14 gets in the way or gives pain when the user U sits down, and the massage mechanism 3 is reliably housed inside the massage device 1 Is possible.
On the other hand, when the massage device 3 of the present invention moves the massage mechanism 3 backward along the above-described guide rail portion 6, the position of the treatment element 14 is temporarily kept away from the treatment portion, in other words, the treatment element 14 It is characterized in that a rail recess 33 is formed on the rear end side of the guide rail, which temporarily lowers the position of the lower than the upper surface of the apparatus main body 2.

The reason for providing such a rail recess 33 is as follows.
That is, when the guide rail portion 6 is disposed at a height (a height at which the treatment element 14 protrudes upward from the upper surface of the apparatus main body 2) at which massage by the treatment element 14 is possible, While maintaining the state, the treatment elements 14 move horizontally toward the rear along the guide rail portion 6 facing in the horizontal direction.

At this time, the user U is seated with his buttocks in contact with the upper surface of the device body 2, but generally the inside of the buttocks is stretched downward in a sitting state such as a coccyx or a sciatic There is a bone that has come out, and if the treatment element 14 is moved backward with the treatment element 14 projected upward, the treatment element 14 moving backward strongly rubs against these bones or the tissues around the bones, resulting in an unpleasant feeling of use. It may be given to the user U. In particular, the treatment elements 14 located at least on the rear side among the front and rear treatment elements 14 easily cause a problem that the treatment section is strongly rubbed.

So, in the massage apparatus 1 of this embodiment, when moving the massaging mechanism 3 back along the guide rail part 6, the rail recessed part 33 which makes the position of the treatment element 14 temporarily separate from a treatment part is a guide rail part. It is formed on the rear end side of 6. In other words, the rail recess 33 temporarily lowers the position of the treatment element 14 below the upper surface of the apparatus body 2.

In addition, since the posture of the massaging mechanism 3 is supported by only one point of the pinion gear 26 only by providing the rail concave portion 33 in the guide rail portion 6, when the pinion gear 26 is moved to the rail concave portion 33, the posture of the massaging mechanism 3 As a result, there is a possibility that the treatment element 14 may rub against the treatment section.
Therefore, in the massage device 1 of the present embodiment, a posture holding mechanism 34 for holding the posture of the massage mechanism 3 moving in the front-rear direction in a stable posture is provided. In other words, the posture holding mechanism 34 is configured to support the massage mechanism 3 in motion at a plurality of points, and to stabilize the posture of the massage mechanism 3 in motion in the front-rear direction.

Next, the rail recessed part 33 and the attitude | position holding mechanism 34 which are provided in the massage apparatus 1 of this embodiment are demonstrated.
The rail recess 33 is arranged such that the rack teeth provided on the rear end side of the guide rail portion 6 are curved downward in a circular arc, in other words, having curved rack teeth that expand downward. It has become. That is, when the pinion gear 26 travels along the rail recess 33, the position of the pinion gear 26 becomes lower than the normal traveling height, and the height of the massaging mechanism 3 provided with the pinion gear 26 also temporarily decreases. Therefore, the treatment element 14 moves downward as much as the height of the massage mechanism 3 is lowered, and the treatment element 14 can be pulled down below the upper surface of the apparatus main body 2.

Although the position in the longitudinal direction in which the rail recess 33 is formed varies depending on the physical size of the user U seated on the upper surface of the device body 2, the dimension in the longitudinal direction of the device body 2, etc. It is preferable to position the rail recess 33 at about 30% of the total length of the apparatus body 2 from the rear end.
Further, the width in the vertical direction of the rail recess 33 is about 3 to 4 times the outer diameter of the treatment element 14 described above. If the rail concave portion 33 is curved in the vertical direction with such a width, the massage mechanism 3 can be smoothly moved rearward, and only the rear treatment element 14 sinks below the upper surface of the apparatus main body 2 It is possible to prevent the treatment element 14 from being strongly rubbed against the treatment section.

As shown in FIG. 5, the posture holding mechanism 34 described above includes two movable bodies projecting outward in the left-right direction from the massaging mechanism 3 and two guide grooves for guiding the two movable bodies in a fitted state, It consists of
The two moving bodies described above are the first moving body 35 disposed further outward of the pinion gear 26 provided on the left and right ends of the rotating shaft 12 and the second moving body disposed forward of the first moving body 35 It consists of two. The two guide grooves are provided with a first guide groove 7 for guiding the first movable body 35 in a fitted state and a second guide groove 8 in which the second movable body 36 is fitted.

Specifically, the first guide groove 7 is formed along the upper side of the guide rail portion 6 as a long groove having the same locus as the guide rail portion 6. That is, the trajectory of the first guide groove 7 has a front end side which curves so as to descend toward the front, and a rear end side provided horizontally along the front-rear direction. Then, a part of the rear end side of the first guide groove 7 is curved so as to be gently recessed downward corresponding to the rail recess 33 of the guide rail.

Further, the second guide groove 8 is disposed at an upper front side than the first guide groove 7 with a distance, and has substantially the same locus as the first guide groove 7. In other words, the second guide groove 8 has a locus that overlaps with the first guide groove 7 when it is moved in parallel.
More specifically, the trajectory of the second guide groove 8 has a front end side curved so as to descend toward the front, and a rear end side extending along the front-rear direction while maintaining the same height. .

There is a portion where the track of the rail is curved corresponding to the rail concave portion 33 of the guide rail portion 6 at the rear end side of the first guide groove 7, but the rail concave portion 33 is at the rear end side of the second guide groove 8. There is no part where the track of the rail is curved corresponding to.
Also, the groove end on the front side of the first guide groove 7 has the same height in the vertical direction with respect to the rail end on the front side of the guide rail portion 6 described above, and is disposed further on the front side of the front end of the guide rail portion 6 ing. On the other hand, the groove end on the rear side of the first guide groove 7 is formed higher in height than the rail end on the rear side of the above-described guide rail portion 6 by the groove width. It is deployed further behind. That is, the first guide groove 7 is formed to be longer in both the front and rear directions than the guide rail portion 6.

The groove end of the second guide groove 8 is disposed apart from the groove end of the first guide groove 7 by approximately the same distance on the front side and the rear side. That is, the groove end on the front side of the second guide groove 8 is positioned on the front upper side with respect to the groove end on the front side of the first guide groove 7, and the groove end on the rear side of the second guide groove 8 is behind the first guide groove 7. The rear end of the second guide groove 8 is positioned above the rail recess 33 of the guide rail, which is likewise located on the front upper side with respect to the side groove end.

On the other hand, the first movable body 35 of the two

movable bodies

35 and 36 fitted into the two

guide grooves

7 and 8 described above is disposed at the center of the base 9 in the front-rear direction and the vertical direction. The second movable body 36 forms a projecting piece 37 projecting a part of the front end side of the base 9 upward with respect to the first movable body 35, and the projecting piece 37 projecting upward as described above. It is formed in the shape of outward projection at the upper end side of. That is, the second movable body 36 is provided on the upper front side as viewed from the first movable body 35.

When the two

movable bodies

35 and 36 are moved from the front to the rear along the two

guide grooves

7 and 8 described above, the posture of the massaging mechanism 3 changes as follows.
As shown in FIG. 6A, when the pinion gear 26 is positioned at the front end of the hanging portion 32 of the guide rail portion 6, the first moving body 35 is positioned at the front end side of the first guide groove 7, and the second moving body 36 is Is located on the front end side of the second guide groove 8. When the pinion gear 26 is moved from the front to the rear along the hanging portion 32 of the guide rail portion 6, the first moving body 35 moves from the front to the rear along the hanging portion on the front end side of the first guide groove 7; The second mover 36 moves from the front to the rear along the hanging portion on the front end side of the second guide groove 8. At this time, since the first guide groove 7 and the second guide groove 8 hang along substantially the same locus, the positional relationship between the first movable body 35 and the second movable body 36 hardly changes during movement. Therefore, the posture during movement does not change, and the treatment elements 14 on the front side and the treatment elements 14 on the rear side move backward while maintaining the posture (horizontal posture) that is almost the same height.

Then, according to the inclination of the hanging portion 32 of the guide rail portion 6, the massaging mechanism 3 becomes higher in position from the lower side to the upper side, and the treatment element 14 is pulled down to the lower side of the upper surface of the device main body 2 It changes to a state of projecting upward from the upper surface of the main body 2.
When the pinion gear 26 eventually reaches a portion where the guide rail portion 6 is horizontal beyond the hanging portion 32 of the guide rail portion 6, the massaging mechanism 3 changes to the posture as shown in FIG. 6B.

In the state shown in FIG. 6B, the first movable body 35 is positioned substantially midway in the front-rear direction of the first guide groove 7 and the second movable body 36 is positioned substantially midway in the front-rear direction of the second guide groove 8. . In this state, since the treatment element 14 is in a state of completely projecting upward from the upper surface of the apparatus main body 2, it is possible to reliably massage the treatment portion of the user U using the treatment element 14 that is projected. It becomes possible. Eventually, when the pinion gear 26 reaches the rail concave portion 33 of the guide rail portion 6, the massaging mechanism 3 changes to the posture as shown in FIG. 6C.

In the state shown in FIG. 6C, the first movable body 35 is located at a portion where the locus is curved downward corresponding to the rail recess 33, but the second movable body 36 does not have a curved portion. (2) The height is not changed since it is on the guide groove 8 as in FIG. 6B. Therefore, only the first movable body 35 located on the rear side descends downward, and the second movable body 36 located on the front side maintains the high position. As a result, the posture of the massage mechanism 3 falls to the rear. That is, although the treatment elements 14 on the front side are projected upward from the upper surface of the apparatus main body 2, the treatment elements 14 on the rear side are pulled down below the upper surface of the apparatus main body 2. There will be no problem of rubbing hard on the part.

Therefore, in the massage device 1 of the present invention, only the rear side treatment element 14 can be sunk below the upper surface of the device main body 2, and the treatment element 14 is prevented from being strongly rubbed by the treatment section. It becomes possible.

For example, in the embodiment described above, the massage mechanism 3 has been described in which the treatment element 14 is extended from below with respect to the treatment unit such as the buttocks, and the massage unit 14 massages so as to pinch the treatment unit. However, the massage mechanism 3 of the present invention may be provided with a pressing mechanism for pressing and massaging the treatment part such as the buttock from the side, in addition to the mechanism for performing the massaging.

Further, in the embodiment described above, the rotational driving force generated by one drive motor 11 is used as the power of the massaging mechanism 3 and the moving mechanism 10. However, the massage apparatus 1 of the present invention may be provided with a plurality of drive motors 11, and the drive motor 11 for operating the massage mechanism 3 and the drive motor 11 for operating the moving mechanism 10 may be separately provided.
Moreover, although the thing which attached the treatment element 14 directly to the front end and back end of the massaging body 13 was mentioned in embodiment mentioned above, biasing of a spring etc. is carried out between the front end of the massaging body 13 and the treatment element 14 A means may be provided. If such biasing means is provided, the load applied to the treatment element 14 from the buttocks can be received by the biasing means, and the load on the buttocks can be dispersed and supported.

Moreover, in embodiment mentioned above, the space | interval of massage body 13 comrades on either side was made constant. However, the massage device 1 of the present invention may be provided with a width adjustment mechanism that makes the distance between the left and right massage bodies 13 variable. For example, as such a width adjusting mechanism, a screw screw is formed on the outer peripheral surface of the rotating shaft 12, and a helical internal tooth to be screwed with the screw screw is formed on the inner peripheral surface of the boss 21 described above. Can be used. In such a width adjustment mechanism, when the rotation shaft 12 rotates, the screw screw of the rotation shaft 12 meshes with the internal teeth of the inner peripheral surface of the boss portion 21, so the rotation shaft 12 and the boss portion 21 Relative position changes in the left and right direction. As a result, it is possible to make the distance between the left and right massage bodies 13 variable.
