And a protruding amount varying means for selecting whether to project. That is, in the chair type massage machine 1 of the present embodiment, the position of the massage mechanism 7 is moved to the position corresponding to the treatment part such as the shoulder, the back, the waist, the buttocks using the vertical movement means, and the protrusion amount varying means is changed. Using either the 1st treatment element 14 or the 2nd treatment element 15 and making it contact the user's treatment part, it is the structure which performs an effective massage with respect to each treatment part.

Next, the first arm 12 and the second arm 13 provided in the massage mechanism 7, the moving rail 8 that guides the massage mechanism 7 in the vertical direction, and the operation of the massage mechanism 7 on the path of the moving rail 8 will be described.
As shown in FIG. 3, FIG. 4A and the like, the massage mechanism 7 described above is provided with a first arm 12 and a second arm 13 that protrude toward the treatment portion side. A first treatment element 14 is provided on the distal end side of the first arm 12, and a second treatment element 15 is provided on the distal end side of the second arm 13. For example, if the state located on the upper end side of the moving rail 8 is used as a reference, the first treatment element 14 is located on the upper front side when viewed from the massage mechanism 7, and the first treatment element 14 is located on the lower lower side when viewed from the massage mechanism 7. Two treatment elements 15 are located. The first arm 12 and the second arm 13 have a common base end side (the same), and the first arm 12 and the second arm 13 can swing integrally through the common base end side. It has become.

That is, the rotation shaft 18 is arranged in a penetrating manner in the left-right direction on the base end side common to the first arm 12 and the second arm 13 described above, and the axis of the rotation shaft 18 described later is used as a reference. The first arm 12 is provided so as to extend toward the radially outer side, and the second arm 13 is provided so as to extend substantially perpendicular to the first arm 12 and extend from the proximal end side toward the radially outer side. The base end sides of the first arm 12 and the second arm 13 are attached so as to be swingable about an axis that faces the left-right direction with respect to the rotation shaft 18 described above.

Further, between the base end side of the first arm 12 and the second arm 13 and the rotary shaft 18, the rotary motion of the rotary shaft 18 is converted into the swing motion of the first arm 12 and the second arm 13. A massage massage means (motion conversion means) is provided for transmission. The massage massage means will be described later.
The 1st treatment element 14 and the 2nd treatment element 15 are members which give a massage effect by contacting a treatment part, and roundness like a sphere is given so that a user may not be pained even if it contacts a treatment part. It is shaped like a band. Specifically, a shaft portion extending along the extending direction of the first arm 12 is formed at the tip of the first arm 12, and the first treatment element 14 is attached to the shaft portion of the first arm 12. It is attached so as to be rotatable around the axis of the shaft portion of one arm 12 (the extending direction of the first arm 12). A shaft portion extending along the extending direction of the second arm 13 is also formed at the tip of the second arm 13, and the second treatment element 15 is attached to the second arm 13 on the shaft portion of the second arm 13. It is attached so as to be rotatable about the axis of the shaft portion (the extending direction of the second arm 13).

As shown in FIG. 1, FIG. 2, FIG. 4A to FIG. 4D, etc., the moving rail 8 is a rail that guides the massage mechanism 7 along the vertical direction, and covers a wide range from the upper shoulder to the lower buttocks. Deployed. Specifically, the massage mechanism 7 of the present embodiment is configured to move the massage mechanism 7 by meshing the pinion gear 19 provided in the massage mechanism 7 with the rack teeth 20 of the moving rail 8. Moreover, the moving rail 8 is provided over the range from a shoulder part to a buttocks part, and the rack tooth | gear 20 which meshes with the pinion gear 19 of an up-and-down moving means is formed in the treatment part side (front side or upper side).

The upper end side and the middle side of the moving rail 8 are inclined obliquely upward from the rear end side of the seat portion 2 toward the rear upper side of the seat portion 2 along the backrest surface 3a of the backrest portion 3 in other words. The massage mechanism 7 is guided to the treatment portion such as the shoulder, back, waist, etc. of the user leaning against the backrest portion 3 and can be brought into contact with the treatment element provided on the massage mechanism 7. It has become. Moreover, the lower end side in the up-down direction of the moving rail 8 is disposed along the front-rear direction (horizontal direction) along the seat surface 2a of the seat portion 2, in other words, substantially parallel to the seat surface 2a. The treatment element can be brought into contact with the treatment part of the user's buttocks. That is, the moving rail 8 is formed by connecting the midway side facing the inclination direction and the lower end side facing the horizontal direction at a midway portion curved so as to draw an arc. The upper side (rear side) of the midway part is a treatment area such as a shoulder, back, and waist, and the lower side (front side) of the midway part is a treatment area of the buttocks.

With respect to the treatment area of the moving rail 8 as described above, the massage mechanism 7 performs treatment by switching the treatment element protruding toward the treatment part to either the first treatment element 14 or the second treatment element 15. It has a configuration. In order to cause the first treatment element 14 and the second treatment element 15 to protrude and retreat, a protrusion amount varying means, which will be described later, is used.
Specifically, as shown in FIG. 4A, when the massage mechanism 7 is located in the treatment area on the upper end side of the moving rail 8, the second treatment element 15 is directed to the side opposite to the treatment unit side (rear). The first treatment element 14 is protruded to the shoulder side (forward), and treatment is performed with the first treatment element 14 protruding forward.

That is, in the state of FIG. 4A, the first arm 12 protrudes forward as viewed from the massage mechanism 7, and the second arm 13 retracts so as to face the direction along the backrest surface 3 a. If it does in this way, the 1st treatment element 14 provided in the front-end | tip of the 1st arm 12 member will be in a state which protrudes ahead, and massages treatment parts, such as a shoulder part and a back, with this 1st treatment element 14 which protruded. Is possible.

4A, since the second treatment element 15 provided at the tip of the second arm 13 member is arranged along the backrest surface 3a, the second treatment element 15 is attached to the treatment section described above. Even if the massage mechanism 7 is moved up and down while the first treatment element 14 is in contact with the treatment portion, the second treatment element 15 does not hinder the movement of the massage mechanism 7.
When the massage mechanism 7 in the position of FIG. 4A is moved downward along the moving rail 8, the treatment target (treatment part) by the first treatment element 14 is changed from the shoulder part to the back, and further to the treatment part below the back. Change. Then, when the massage mechanism 7 reaches the position shown in FIG. 4B, the first treatment element 14 can treat the treatment portion of the lower back.

Even in the state of FIG. 4B in which the first treatment element 14 can treat the lumbar region, the first arm 12 extends forward as viewed from the massage mechanism 7 and the second arm 13 faces the direction along the backrest surface 3a. It is possible to massage the treatment part of the lower back with the first treatment element 14 that is retracted to the front and protrudes forward.
However, when the massage mechanism 7 reaches the moving rail 8 ahead of FIG. 4B, the above-described treatment area changes from one corresponding to the shoulder or waist to one corresponding to the buttocks. And if a treatment area switches, the treatment element which treats a treatment part will also switch from the 1st treatment element 14 to the 2nd treatment element 15. FIG.

Specifically, as shown in FIG. 4C, when the massage mechanism 7 reaches the treatment area on the lower end side of the moving rail 8, the first arm 12 and the second arm 13 are connected to the proximal end by using the protrusion amount varying means described later. The first treatment element 14 that is swung rearward (in the direction of the arrow in FIG. 4C) about the axis of the rotating shaft 18 on the side is retracted. At the same time, the second treatment element 15 that has fallen along the backrest surface 3a is swung rearward and protrudes upward.

As a result, as shown in FIG. 4D, the second treatment element 15 projecting upward can be brought into contact with the buttocks so that the second treatment element 15 can treat the buttocks.
The operation of the massage mechanism 7 described above is for moving the massage mechanism 7 downward along the moving rail 8, but the same applies to the case where the massage mechanism 7 is moved upward along the moving rail 8. Operation is performed. That is, when the massage mechanism 7 moves along the moving rail 8 and the position of the massage mechanism 7 changes from the lower (front) treatment area to the upper (rear) treatment area, the first arm 12 and the second arm 12 The arm 13 is swung forward (in the direction of the arrow in FIG. 4D) about the axis of the rotation shaft 18 on the proximal end side, and the second treatment element 15 protruding upward is retracted and moved downward. The operation | movement which makes the 1st treatment element 14 which retracted to protrude upwards is performed.

As described above, if the treatment element that moves the massaging mechanism 7 while moving along the moving rail 8 is switched between the first treatment element 14 and the second treatment element 15, This is advantageous when performing treatment.
That is, the second arm 13 is extended from the massage mechanism 7 located on the lower end side of the moving rail 8 toward the front upper side, and the treatment of the buttocks is performed using the second treatment element 15 on the distal end side of the second arm 13. If it does, the 2nd treatment element 15 can be reached to the front side by the length of the 2nd arm 13. In other words, even if the moving rail 8 is shortened by the length of the second arm 13, it is possible to treat the buttocks. Therefore, even when the lower end of the moving rail 8 is located behind the buttocks, that is, the moving rails. Even when the length of 8 is short, the treatment element can be brought into contact with the buttocks to reliably perform the massage.

In addition, with such a configuration, it is not necessary to ensure the length of the moving rail 8 in the front-rear direction, so that the device configuration is simplified and the manufacturing cost can be reduced. For example, as shown in FIG. 2, even if the lower end of the moving rail 8 is located on the rear side of the center side in the front-rear direction of the seat portion 2, the buttocks are reliably massaged by the massage mechanism 7. It becomes possible.

Furthermore, in the case of the configuration described above, a space that can accommodate the footrest portion 5 (a space in which the accommodation chamber 11 can be formed) is secured below the front portion of the seat portion 2 because the length of the moving rail 8 is short. It becomes possible, and it becomes possible to provide the massage function of a buttocks also to the chair type massage machine 1 of the type which accommodates the footrest part 5 under the seat part 2. FIG.
The second arm 13 is compared to the grip arm 16 or the first arm 12 of the grip massage means so that the second treatment element 15 can be brought into contact with the buttocks located further forward of the lower end (end) of the moving rail 8. And it is preferable that it is long. If the length of the second arm 13 is longer than that of the first arm 12, the second arm 13 is moved more than the first arm 12 by extending the second arm 13 forward while retracting the first arm 12. The rail 8 can be extended further forward, and the second treatment element 15 can be brought into contact with the buttocks even if the moving rail 8 is short. Further, if the length of the second arm 13 is longer than that of the gripping arm 16, the weight of the user is held on the gripping treatment element 17 when the second arm 13 protrudes forward (when projecting to the seat side). Can be avoided, and it is possible to prevent breakage of the grasping treatment element 17 that is used for grasping and is not supposed to be applied with a high load.

By the way, the chair type massage machine 1 of the present invention may be anything provided with the moving rail 8 and the massage mechanism 7 described above, and the configuration of the vertically moving means, the massaging massage means, the gripping massage means, and the protrusion amount varying means is as follows.

A first annular fitting portion 24 provided on the proximal end side of the first arm 12 and the second arm 13 is fitted (externally fitted) to the outer peripheral side of the inclined boss portion 23. The first annular fitting portion 24 is an annular member whose center is open in the left-right direction, and is formed so as to be fitted to the inclined cam surface from the outside. That is, by fitting the first annular fitting portion 24 slidably along the inclined cam surface, the first arm 12 and the second arm 13 described above are rotatable (swinging) with respect to the rotating shaft 18. Is free).

Further, as shown in FIG. 7, a protruding piece 25 protruding toward the opposite side of the extending direction of the first arm 12 and the second arm 13 is provided on the base end side of the first arm 12 and the second arm 13. The connecting shaft 26 is connected to the tip of the protruding piece 25. The connecting shaft 26 connects the base end sides of the first arm 12 and the second arm 13 to the base 27 side (a member drawn in phantom lines in FIG. 7 and a member corresponding to the casing of the massage mechanism 7). In this configuration, the base end sides of the first arm 12 and the second arm 13 are restricted from rotating integrally with the inclined boss portion 23. Further, on the front side of the massage mechanism 7, a stagnation drive motor 28 that rotationally drives the rotary shaft 18 described above is provided with the drive shaft facing downward, and the rotational drive force generated by the stagnation drive motor 28 is transmitted. Thus, the rotary shaft 18 can be driven to rotate about an axis that faces in the left-right direction.

In other words, in the massaging massage means, the rotational drive force generated by the massaging drive motor 28 is transmitted so that the rotary shaft 18 rotates about the axis that faces in the left-right direction, and the inclined boss that can rotate integrally with the rotary shaft 18. The part 23 also rotates. Then, the base end sides of the first arm 12 and the second arm 13 also try to rotate integrally with the inclined boss portion 23 along the inclined cam surface that goes around the axis intersecting the axis of the rotation shaft 18. However, the base end sides of the first arm 12 and the second arm 13 are fixed to the base 27 side by the connecting shaft 26 described above, and the base end sides of the first arm 12 and the second arm 13 are connected to the inclined boss portion 23. It does not rotate together. For this reason, the first arm 12 and the second arm 13 repeatedly swing back and forth in the left-right direction in a state where the rotation around the axis of the rotation shaft 18 is restricted, and the first arm 12 and the second arm 13 come to the ends of the first arm 12 and the second arm 13. The first treatment element 14 and the second treatment element 15 provided also swing in the left-right direction, and it is possible to massage the treatment part by sandwiching the treatment part between these treatment elements.

Similar to the first and second arms 13 described above, the gripping massage means includes a gripping arm 16 that protrudes toward the treatment portion side, and a gripping treatment element 17 disposed on the distal end side of the gripping arm 16. ing.
The position on the rotary shaft 18 where the gripping arm 16 is provided is on the inner side in the width direction of the rotary shaft 18 than the proximal ends of the first and second arms 13 on the rotary shaft 18 and adjacent to the inclined boss portion 23. It is attached to the position.

Specifically, the gripping massage means includes an eccentric boss portion 29 that can rotate integrally with the rotary shaft 18 in the same manner as the inclined boss portion 23. On the outer peripheral surface of the eccentric boss portion 29, an eccentric cam surface having a circular orbit that is eccentric with respect to the axis of the rotary shaft 18 is formed, and when the rotary shaft 18 is rotated, the eccentric cam surface becomes the rotary shaft 18. It is designed to draw a circular orbit that is eccentric with respect to the axis. Then, a second annular fitting portion 30 formed in an annular shape is fitted to the eccentric cam surface of the eccentric boss portion 29 from the outside so as to be slidable along the eccentric cam surface. The second annular fitting portion 30 is provided on the proximal end side of the gripping arm 16.

The gripping arm 16 has projections 31 protruding outward in diameter (side away from the axis of the rotating shaft 18) so as to be substantially orthogonal to the base end side that is rotatably connected to the rotating shaft 18. Two are provided. Of the two

protrusions

31a and 31b, the above-described grasping treatment element 17 is provided at the tip of one protrusion 31a (the protrusion 31a positioned on the lower side in FIG. 6). Further, a restriction pin 32 for restricting the swinging direction of the gripping arm 16 is formed at the tip of the other protrusion 31b (the protrusion 31b positioned on the upper side in FIG. 6) so as to protrude inward in the width direction. ing. The restriction pin 32 is fitted in a restriction groove 33 (a portion indicated by a dotted line in FIG. 6) formed in a cover or the like of the backrest 3. Further, the restriction groove 33 is formed along a direction substantially parallel to the above-described moving rail 8, that is, along the vertical direction, and the restriction pin 32 can be guided along the formation direction of the restriction groove 33.

Therefore, when the rotary shaft 18 is rotated using the squeezing drive unit (stagnation drive motor 28), the proximal end side of the grip arm 16 is positioned along the eccentric cam surface that rotates around the axis of the rotary shaft 18 in an eccentric manner. An attempt is made to rotate around the 18 axis in an eccentric state. At this time, since the restriction pin 32 of the protrusion 31 provided on the gripping arm 16 is fitted in the restriction groove 33, the gripping arm 16 does not rotate integrally with the eccentric boss part 29. Further, since the restriction pin 32 is only allowed to move in the vertical direction while being fitted in the restriction groove 33, the tip of the protrusion 31 of the gripping arm 16 provided with the gripping treatment element 17 repeats in the front-rear direction. Repeat the move. In this manner, the first treatment element 14 of the first arm 12 that swings in the left-right direction comes relatively close to or away from the grip treatment element 17 that repeatedly moves in the front-rear direction. It becomes possible to sandwich and hold the treatment portion between the treatment element 17 and the first treatment element 14 and perform massage.

In contrast to the above-described embodiment, the restriction groove 33 may be formed on the gripping arm 16 side, and the restriction pin 32 may be fixedly provided at a position facing it (for example, inside the cover). That is, the positions of the regulation pin 32 and the regulation groove 33 may be reversed.
Further, the member indicated by reference numeral 32 does not necessarily have to be a pin (rod), and may be any member that engages with the member indicated by reference numeral 33 and prevents the grip arm 16 from rotating around the rotating shaft 18.

As shown in FIG. 7, on the proximal end side of the first arm 12 and the second arm 13, there is a protruding piece 25 that protrudes toward the side opposite to the direction in which the first treatment element 14 and the second treatment element 15 extend. The connecting shaft 26 is connected to the tip of the projecting piece 25. The connecting shaft 26 is attached to the tip of the projecting piece 25 so as to be swingable about an axis by a ball bearing mechanism with respect to an axis facing in the left-right direction. Further, the end of the connecting shaft 26 opposite to the protruding piece 25 is connected to a base 27 of the massage mechanism 7, more specifically, a tapping drive shaft 34 provided on the rear side of the massage mechanism 7.

Specifically, the tapping drive shaft 34 is a shaft attached in the left-right direction similarly to the rotating shaft 18, and can be driven to rotate by a tapping drive motor 35 disposed on the rear side of the massage mechanism 7. . Cylindrical hitting bosses 36 are attached to both ends of the hitting drive shaft 34 extending in the left-right direction in a state of being eccentric with respect to the axis of the hitting drive shaft 34. When the hitting drive shaft 34 rotates, the hitting drive shaft 34 hits. The boss portion 36 rotates eccentrically. An end portion of the connecting shaft 26 is freely fitted on the outer peripheral surface of the hitting boss portion 36 so that the end portion of the connecting shaft 26 can swing in the vertical direction.

That is, when the tapping drive shaft 34 is rotated by the tapping drive motor 35, the tapping boss portion 36 attached to the tapping drive shaft 34 in an eccentric state rotates eccentrically around the axis of the tapping drive shaft 34, and the end of the connecting shaft 26 Similarly, the part rotates eccentrically. Then, in accordance with the eccentric rotation of the end portion of the connecting shaft 26, the proximal end sides of the first arm 12 and the second arm 13 are repeatedly rotated around the axis of the rotation shaft 18 so as to repeat normal rotation and reverse rotation. The first treatment element 14 provided on the distal end side of the first arm 12 and the second treatment element 15 provided on the distal end side of the second arm 13 are alternately pressed strongly against the treatment part, It is possible to perform a tapping massage on the part.

The protrusion amount varying means is for projecting either the first treatment element 14 or the second treatment element 15 to the treatment part side (front side), and the treatment element for treating the treatment part is the first treatment. It is possible to switch between the child 14 and the second treatment element 15.
The protrusion amount varying means includes a rod-shaped guide portion 37 disposed on the base 27 side in parallel with the laying direction of the moving rail 8. Two guide portions 37 are provided in parallel to each other on the left and right sides of the massage mechanism 7, and both ends thereof are fixed to the base 27. A guide body 38 is attached to the middle portion of the guide portion 37 in the longitudinal direction so as to be movable along the installation direction of the guide portion 37.

Specifically, the guide body 38 is a plate-like member provided so as to straddle both the pair of left and right guide portions 37, and the guide portion 37 is provided on the surface of the guide body 38 on the guide portion 37 side. A restricting portion 39 having an insertion hole for insertion is provided. Two restricting portions 39 are provided at a predetermined interval with respect to one guide portion 37, and the guide body 38 is interposed via a total of four restricting portions 39 provided across the two guide portions 37. The guide portion 37 can be guided along the laying direction (vertical direction) of the guide portion 37.

Further, a slide body 40 is provided between the two restricting portions 39 in the guide portion 37, which is shorter than the interval between the restricting portions 39 and can move the guide portion 37 between the restricting portions 39. The slide body 40 is movable using the rotational driving force of the arm protrusion motor 41.
Specifically, the arm protrusion motor 41 is arranged with the drive shaft directed in the front-rear direction, and is capable of rotating the second pinion gear 42 having the axis centered in the front-rear direction. The second pinion gear 42 meshes with the second rack teeth 43 arranged in the vertical direction so as to be parallel to the moving rail 8, and the second pinion gear 42 is meshed with the second pinion gear 42 by rotating the second pinion gear 42. The two rack teeth 43 move in a direction parallel to the moving rail 8. The second rack teeth 43 and the slide body 40 described above are fixed and can move together. Therefore, by driving the arm protrusion motor 41, the slide body 40 can be moved in a direction parallel to the moving rail 8.

For example, as shown in FIG. 8, the slide body 40 moved downward along the direction parallel to the moving rail 8 eventually becomes a restriction part 39 (positioned below) of the two restriction parts 39 described above. It abuts on the first restricting part 39a). Then, the guide body 38 also moves downward along the guide portion 37 integrally with the slide body 40. As a result, the position of the end portion of the connecting shaft 26 (the position on the side where the hitting boss portion 36 is provided) changes downward, and is pulled by the connecting shaft 26 so that the base end sides of the first arm 12 and the second arm 13 are It swings downward about the axis of the rotating shaft 18. Then, as shown in FIG. 9, the distal end of the first arm 12 swings downward about the proximal end side, and the first treatment element 14 provided at the distal end of the first arm 12 moves backward. . Further, the distal end of the second arm 13 swings downward about the base end side, the second treatment element 15 provided at the distal end of the second arm 13 projects forward, and the second treatment element 15 projects forward. It becomes possible to massage the treatment part of the buttocks with (the lower fir ball).

On the other hand, when the arm protrusion motor 41 is rotated in the opposite direction to the above-described case, the slide body 40 moved upward along the direction parallel to the moving rail 8 will eventually become one of the two restriction portions 39 described above. , Abuts on the upper restriction part 39 (second restriction part 39b). As a result, the guide body 38 also moves upward along the guide portion 37 together with the slide body 40. As a result, the position of the end portion of the connecting shaft 26 (the position on the side where the hitting boss portion 36 is provided) changes upward, and the proximal end sides of the first arm 12 and the second arm 13 are pulled by the connecting shaft 26. It swings upward about the axis of the rotary shaft 18. Then, as shown in FIG. 8, the second treatment element 15 provided at the distal end of the second arm 13 moves backward, and the first treatment element 14 provided at the distal end of the first arm 12 protrudes forward, thereby protruding forward. It becomes possible to massage the shoulder, back, and lower back treatment areas with the first treatment element 14 (the upper fir tree ball).

If the second arm 13 protrudes to the treatment portion side instead of the first arm 12 in this way, the second treatment element 15 can reach the front by the length of the second arm 13, and the seat portion Even if the moving rail 8 having such a short length as to terminate at the rear end side of the 2 is used, it is possible to reliably massage the treatment portion of the user's buttocks.
