The back portion guide rail 7 extends along the inclination direction of the backrest portion 3 while being gently curved so as to be substantially parallel to the vertical beam member 10a. The width interval between the pair of left and right back guide rails 7 is wider than the user's head.

A rack portion 12 is formed on the front side of the back guide rail 7 so as to mesh with a travel gear 11 to be described later. By engaging the travel gear 11 with the rack portion 12, the back massage mechanism 6 is attached to the back guide rail 7. It is possible to guide in the vertical direction along.
The back massage mechanism 6 generates a rotational driving force by a stagnation drive unit (drive motor) provided in the back massage mechanism 6, converts the generated rotational driving force using a cam, and moves the massage arm 13 in the left-right direction. Reciprocally swing. That is, the back massage mechanism 6 includes the massage arms 13 on the left side and the right side of the back massage mechanism 6, and a treatment element 14 for treating the treatment part of the back is attached to the tip of each massage arm 13. ing. The back massage mechanism 6 is configured to perform massage such as squeezing, grasping, and hitting the treatment portion using the treatment element 14 by swinging the left and right massage arms 13 in a desired speed and direction. .

Specifically, the back massage mechanism 6 of the present embodiment includes a squeezing mechanism for performing massage massage, a slashing mechanism for performing massage massage, and a gripping mechanism for performing massage massage on the treatment unit on the back of the user. . Only one of these mechanisms may be provided, or a plurality of these mechanisms may be provided in combination.
For example, the stagnation mechanism according to the present embodiment will be described as an example. Here, a cylindrical eccentric boss member 15 is attached to the stagnation rotation shaft, and a cam surface is formed on the outer peripheral surface of the eccentric boss member 15. The cam surface circulates around an axis inclined with respect to the axis of the stagnation rotation shaft, and the proximal end side of the massage arm 13 is rotatably fitted to the cam surface. In addition, on the proximal end side of the massage arm 13, a restricting member that restricts the rotation of the massage arm 13 while allowing movement along the left-right direction is provided. Therefore, when the stagnation rotation shaft is rotated using the stagnation drive unit, the cylindrical eccentric boss member 15 also rotates around the axis facing the left-right direction. On the other hand, since the rotation of the massage arm 13 is restricted by the restriction member, the massage arm 13 whose rotation with the eccentric boss member 15 is restricted only swings along the left and right directions along the cam surface. Become. Therefore, in the above-mentioned massage mechanism, massage massage can be performed by swinging the massage arm 13 in the left-right direction and using the treatment element 14 to massage the treatment portion.

The back massage mechanism 6 of the present embodiment has a treatment element 14 hitting the treatment portion at a short pitch by reciprocatingly swinging the proximal end side of the massage arm 13 at a short pitch, in addition to the above-described massage mechanism. In addition, a tapping mechanism for performing tapping massage on the treatment portion is provided. Further, in the back massage mechanism 6 of the present embodiment, a separately provided gripping treatment element 16 is moved toward and away from the treatment element 14 of the massage arm 13, so that the

treatment element

14, 16 is moved between the

treatment elements

14 and 16. A gripping mechanism is also provided that performs gripping massage on the treatment unit by operating the treatment unit so as to grip the treatment unit. However, these hitting mechanisms and gripping mechanisms have little relation to the features of the present invention (the mechanism for moving the pillow member 17 and the pillow member 17 back and forth), and therefore will not be described in detail below.

On the other hand, the back massage mechanism 6 described above is provided with an elevating mechanism 18 that moves the back massage mechanism 6 in the vertical direction along the back guide rail 7.
The elevating mechanism 18 rotates the traveling gear 11 meshed with the rack portion 12 of the back guide rail 7 by using the rotational driving force generated by the elevating drive unit (not shown) provided in the back massage mechanism 6, The massage mechanism 6 is configured to move up and down along the laying direction of the rack portion 12. Specifically, the elevating mechanism 18 is a shaft that is directed to the left and right directions by being transmitted with the elevating drive unit (elevating motor) provided on the rear side of the back massage mechanism 6 and the rotational driving force generated by the elevating drive unit. A lifting shaft 19 that rotates around and a traveling gear 11 provided on both ends of the lifting shaft 19 are provided. That is, when the traveling gear 11 is rotated in one direction using the elevating drive unit, the traveling gear 11 meshes with the rack portion 12 of the back guide rail 7 and travels upward through the rack portion 12, and the back massage mechanism 6. Moves (ascends) toward the upper part of the backrest 3. On the other hand, when the traveling gear 11 is rotated in the opposite direction (the other direction) as it is raised, the traveling gear 11 meshes with the rack portion 12 of the back guide rail 7 and travels downward on the rack portion 12, The massage mechanism 6 moves (lowers) toward the lower part of the backrest 3.

By the way, the chair type massage machine 1 of the present invention moves the back massage mechanism 6 in the vertical direction along the back guide rail 7 by using the lifting mechanism 18 described above, and is located away from the user's head. When the back massage mechanism 6 is shifted to the top, the pillow member 17 capable of supporting the user's head advances from the backrest 3. That is, the pillow member 17 of the chair type massage machine 1 according to the present invention fills the opening (the part that does not support the user) formed in the backrest part 3 of the trace where the back massage mechanism 6 has moved. It can appear at the back of the part.

In the case of the chair type massage machine 1 of the present embodiment, the pillow member 17 advances in conjunction with the back massage mechanism 6 being lowered to a desired height, but the chair type massage machine of the present invention. The advancing means 20 of the pillow member 17 provided in 1 may not be interlocked with the lowering. For example, a configuration in which the pillow member 17 is advanced in conjunction with the back massage mechanism 6 rising to a desired height may be adopted, or the back massage mechanism 6 is separated by a predetermined height upward and downward. A configuration may be adopted in which the pillow member 17 is advanced in conjunction with the movement.

Specifically, the chair type massage machine 1 of the present embodiment includes a pillow member 17 that can support the user's head, an advancement means 20 that advances the pillow member 17 forward of the backrest portion 3, and an advancement forward. And pull-back means 21 (in other words, retracting means) for pulling back the pillow member 17 backward. The advancing means 20 operates in conjunction with the downward movement of the back massage mechanism 6, that is, when the back massage mechanism 6 is lowered to a desired height. The pull-back means 21 is interlocked with the upward movement of the back massage mechanism 6, that is, when the back massage mechanism 6 has risen beyond a desired height.

Next, the pillow member 17, the advancing means 20, and the pullback means 21 that are the features of the chair type massage machine 1 of the present invention will be described.
The pillow member 17 is formed in a slightly elongated rectangular or cylindrical shape along the left-right direction so as to be able to support the user's head, and has elasticity so that the user's head can be softly supported. It is made of a cushion material. The pillow member 17 of the present embodiment shown in FIG. 3 has a semicircular cross-sectional shape perpendicular to the left-right direction, and the side that is curved in an arc shape in the cross-sectional shape is forward so that it does not hurt even if it is twisted. It projects from the backrest 3 so as to face.

Further, the length (width in the left-right direction) along the left-right direction of the pillow member 17 is shorter than the distance between the left and right back guide rails 7. Further, the left end of the pillow member 17 is located inside the left back guide rail 7, the right end of the pillow member 17 is located inside the right back guide rail 7, and the pillow member 17 is It is provided at a position where it does not interfere with any of the back guide rails 7. If such a pillow member 17 is used, the pillow member 17 can be freely moved (swinged) in the front-rear direction through the space between the left and right back guide rails 7.

The advancing means 20 is a means for advancing the pillow member 17 in front of the backrest 3. In the case of the present embodiment, the advancing means 20 is provided with respect to the back frame 10 and the swing arm 22 that supports the pillow member 17 so as to be swingable about an axis directed in the left-right direction with respect to the back frame 10 described above. And the urging member 23 that enables the pillow member 17 to advance by urging the swing arm 22. In this embodiment, the advancing means 20 advances the pillow member 17 using the urging force of the urging member 23. However, instead of the urging force of the urging member 23, a swing arm 22 is used using a linear actuator or the like. The pillow member 17 may be advanced by swinging.

Specifically, the swing arm 22 provided in the advancing means 20 of the present embodiment is an elongated rod-like member provided on both the left and right sides of the pillow member 17, and the pillow member 17 is moved in the front-rear direction with respect to the backrest portion 3. It is the structure supported so that rocking | fluctuation is possible. That is, the base end side of the swing arm 22 is pivotally supported by the pivot shaft 24 provided slightly above the midway side in the vertical direction of the back frame 10, and the pivot shaft 24 is supported by the support frame 8. The swing arm 22 is attached to the crosspiece member 10b using an attachment member 25, and the swing arm 22 is swingable in the front-rear direction via a pivot shaft 24 having an axial center in the left-right direction.

The front end side of each swing arm 22 is fixed to the left and right side surfaces of the pillow member 17, and the swing arm 22 can support the pillow member 17 on both the left and right sides. The swing arm 22 in the longitudinal direction, that is, the swing arm 22 between the pivot shaft 24 and the pillow member 17 is bent in a substantially S shape. Further, each swing arm 22 extends further rearward than the pivot shaft 24. The rear portion of the pivot shaft 24 has a different configuration for the left swing arm 22 and the right swing arm 22.

In other words, the rear portion (rear end portion) of the right swing arm 22 with respect to the pivot shaft 24 is bent slightly rearward of the back guide rail 7 toward the outer side (right side) in the width direction. After being pushed, it extends rightward and terminates at a position beyond the right back guide rail 7. On the other hand, the rear part (rear end part) of the left swing arm 22 from the pivot shaft 24 is bent slightly rearward of the back guide rail 7 toward the outer side (left side) in the width direction and bent. It also extends toward the left and bends a plurality of times at a position beyond the left back guide rail 7 and then ends slightly above the pivot shaft 24. The urging member 23 described above is attached to the end portion of the left swing arm 22.

The urging member 23 is attached to the terminal portion (the base end side located rearward of the pivot shaft 24) of the left swing arm 22 described above and swings the swing arm 22 forward. It is a member that urges Specifically, the urging member 23 provided in the chair type massage machine 1 of the present embodiment includes a terminal portion of the left swing arm 22, a backrest portion 3 (a rear casing that covers the backrest portion 3), It is composed of springs deployed between. This spring (the biasing member 23) generates a biasing force so as to pull up the end portion of the swing arm 22 upward, so that the distal end side of the swing arm 22 extending forward with the pivot shaft 24 interposed therebetween. It is configured to be biased in the direction of swinging forward.

That is, in the advancing means 20 described above, the urging member 23 generates an urging force so as to pull up the end portion of the oscillating arm 22 upward, and the oscillating arm 22 is directed forward around the pivot shaft 24. The pillow member 17 supported at the tip of the swing arm 22 advances forward.
On the other hand, the chair type massage machine 1 of the present embodiment is provided with a pull back means 21 (retracting means) for pulling back the pillow member 17 that has advanced forward by the advance means 20 backward. Specifically, when the back massage mechanism 6 moves downward, the pull-back means 21 uses the jumping member 26 provided on the back surface of the back massage mechanism 6 as a jump piece provided on the swing arm 22. 27, the swinging arm 22 is pushed back in the opposite direction (backward, in other words, in the back) from the time of forward advancement.

Specifically, the jumping member 26 is a rectangular bar-like member that is attached to the right side of the back massage mechanism 6 and extends along the longitudinal direction of the backrest 3. The jumping member 26 is attached to the slightly left side of the right back guide rail 7 and is configured to abut on the jumping piece 27 of the swing arm 22 at the rear end face. Further, the jumping piece 27 is a member arranged on the front side (the pillow member 17 side) of the pivot shaft 24 in the right swing arm 22, and protrudes toward the left (in the width direction). The rear end surface of the back massage mechanism 6 can be brought into contact with the rear end surface. That is, the rear end surface of the jumping member 26 is a vertical surface that stands up and down along the vertical direction, and is curved forward as it goes upward, and has a warped shape in rear view. Yes. When the back massage mechanism 6 moves upward, the jumping piece 27 can be slid downward along the curved rear end surface.

Therefore, in the above-described pull-back means 21, when the back massage mechanism 6 is moved upward, the jump member 26 provided on the right side of the back massage mechanism 6 contacts the jump piece 27 of the right swing arm 22. When the back massage mechanism 6 is moved further upward, the jumping piece 27 of the swing arm 22 moves upward along the curved rear end surface, and the position where the jumping piece 27 contacts the jumping member 26 is shifted backward. Thus, the swinging arm 22 is pushed back in the direction opposite to the urging direction (backward, in other words, in the back) by the jumping member 26 that moves upward. As a result, the pull-back means 21 can pull back the pillow member 17 advanced forward by the advance means 20 toward the rear.

In order to prevent the pillow member 17 that has advanced forward from further swinging and drooping downward, and to be securely fixed at that position, positioning means 28 for positioning the pillow member 17 at the advanced position is provided. Also good. As such positioning means 28, as shown by a two-dot chain line in FIG. 2, a belt or the like that connects the pillow member 17 and the back frame 10 can be employed. By providing such a belt, the pillow member 17 can be reliably positioned at the advanced position.

In addition, when the swing arm 22 swings forward, an attachment member 25 that is used when the pivot shaft 24 is attached to the crosspiece member 10b may be provided at a position where the swing arm 22 swings forward. it can. In this way, the swing arm 22 swinging forward is brought into contact with the mounting member 25, and the pillow member 17 can be positioned at the advanced position. That is, in this case, the attachment member 25 acts as positioning means 28 for positioning the pillow member 17 at the advanced position.

Next, an operation of moving the pillow member 17 forward using the above-described advancement means 20 and an operation of pulling back the pillow member 17 backward using the pullback means 21 will be described.
First, as shown in FIG. 5, when the back massage mechanism 6 is located behind the user's head (above the backrest 3), the pillow member 17 is pulled back (within the backrest 3). It is in the state.

That is, in the back massage mechanism 6 shown in FIG. 5, the jump piece 27 of the right swing arm 22 is in contact with the lower side of the rear end surface of the jump member 26, and the swing arm 22 is supported by the pivot shaft 24. It is a posture that is largely pulled backwards around the center. The swing arm 22 described above is arranged so as to extend upward and downward from the pivot shaft 24, and the pillow member 17 is positioned substantially above the pivot shaft 24. That is, the pillow member 17 in FIG. 5 is located behind the back guide rail 7. If the pillow member 17 is positioned rearward of the back guide rail 7 in this way, the pillow member 17 does not interfere with the vertical movement of the back massage mechanism 6 and the back massage mechanism 6 can be smoothly moved up and down. Is possible.

When the back massage mechanism 6 shown in FIG. 5 is moved downward along the back guide rail 7 (when the back massage mechanism 6 is moved to a position away from the user's head), the jumping piece 27 and the jumping member 26 are moved. The jumping member 26 is lowered downward while maintaining a sliding state with the rear end surface. Eventually, the jump piece 27 is positioned on the curved rear end surface (curved surface) formed on the upper side of the jump member 26. Then, as shown in FIG. 4, the contact position of the jumping piece 27 with respect to the rear end surface of the jumping member 26 shifts to the front, and the swing arm 22 described above swings slightly forward about the pivot shaft 24. To move.

That is, in the back massage mechanism 6 shown in FIG. 4, the swing arm 22 is swung forward in conjunction with the downward movement of the jumping member 26. Therefore, the urging member 23 of the advancement means 20 causes the tip end side of the swing arm 22 to swing forward around the pivot shaft 24, and the pillow member 17 advances forward from the position shown in FIG.
Eventually, when the back massage mechanism 6 is further moved downward along the back guide rail 7, the upper end edge of the jumping member 26 moves downward relative to the jumping piece 27, and with respect to the rear end surface of the jumping member 26. The jumping piece 27 is prevented from contacting.

Then, as shown in FIG. 3, the swing arm 22 further swings forward around the pivot shaft 24, and the pillow member 17 supported at the tip of the swing arm 22 moves forward of the pivot shaft 24. To advance to.
The above-described operations from FIG. 5 to FIG. 3 were for moving the pillow member 17 forward, but when pulling the pillow member 17 backward, the procedure reverse to that for the forward movement (FIG. 3 → FIG. 4) was performed. → By performing FIG. 5, it is possible to pull back the pillow member 17 that has advanced forward.

In the chair type massage machine 1 of this embodiment mentioned above, even if it is a case where the back massage mechanism 6 is moved to the position away from the head downward using the lifting mechanism 18, the back massage mechanism 6 is moved. The pillow member 17 can be advanced to the position and the user's head can be supported by the pillow member 17. Therefore, in the chair type massage machine 1 of the present embodiment, even when the back massage mechanism 6 cannot support the user's head, the head can be supported in a stable posture.

In addition, it should be thought that embodiment disclosed this time is an illustration and restrictive at no points.
