However, since the squeezing mechanism or the grasping mechanism has no relationship with the features of the present invention (the pillow member 17 and the mechanism for advancing and retracting the pillow member 17), detailed description thereof will be omitted hereinafter.

On the other hand, the back massage mechanism 6 is provided with a lifting mechanism 18 that moves the back massage mechanism 6 itself in the vertical direction along the back rail 7.

The elevating mechanism 18 rotates the traveling gear 11 that meshes with the rack portion 12 of the back rail 7 by the rotational driving force generated by the elevating drive unit (not shown) provided in the back massage mechanism 6, so that the back massage is performed. The mechanism 6 is configured to ascend and descend along the laying direction of the rack portion 12. Specifically, the elevating mechanism 18 includes a lifting/lowering driving unit (elevating motor) provided on the rear side of the back massage mechanism 6, and a lifting shaft 19 for transmitting the rotational driving force generated by the elevating driving unit and rotating around The shaft rotation in the direction; and the traveling gear 11 are provided on both end sides of the lifting shaft 19. In other words, when the traveling gear 11 is rotated in one direction by the driving unit for lifting, the traveling gear 11 is engaged with the rack portion 12 of the back rail 7 and the rack portion 12 is moved upward, and the back massage mechanism 6 is moved toward the backrest portion 3. The upper part moves (rises). On the other hand, when the traveling gear 11 is rotated in the opposite direction (the other direction) as when it is raised, the traveling gear 11 is engaged with the rack portion 12 of the back rail 7, and the rack portion 12 is moved downward, and the back massage is performed. The mechanism 6 is moved (dropped) toward the lower portion of the backrest portion 3.

However, the chair type massage machine 1 of the present invention is characterized in that the back massage mechanism 6 is moved in either of the upper and lower directions along the back rail 7 using the above-described lifting mechanism 18, and the back massage mechanism 6 is moved to move away from the user's head.

Further, the left end of the pillow member 17 is located on the inner side of the left side back rail 7, the right end of the pillow member 17 is located on the inner side of the right rear guide rail 7, and the pillow member 17 is disposed not to interfere with the left and right back rails 7 The location of one. When the pillow member 17 is used, the pillow member 17 can be freely moved (swinged) between the right and left back rails 7 in the front-rear direction.

The extension means 20 is a means for extending the pillow member 17 in front of the backrest portion 3. In the case of the present embodiment, the extension means 20 is constituted by the swing arm 22 and the potential energy imparting member 23, and the swing arm 22 supports the pillow member 17 so as to be swingable around the axis in the left-right direction. The potential energy imparting member 23 extends the pillow member 17 to the back frame 10 by imparting potential energy to the swing arm 22. In the extension device 20 of the present embodiment, the pillow member 17 is extended by using the potential energy imparting force A of the potential energy imparting member 23, but the potential energy imparting force A may be used instead of the potential energy imparting member 23 by using a linear actuator or the like. The swing arm 22 is swung to thereby extend the pillow member 17.

Specifically, the swing arm 22 provided in the extension device 20 of the present embodiment is an elongated rod-shaped member provided on the left and right sides of the pillow member 17, and is configured to support the pillow member 17 so as to be swingable in the front-rear direction. Backrest portion 3. That is, the base end side of the swing arm 22 is pivotally supported by a pivot shaft 24 provided slightly above the midway side of the lower frame 10, and the pivot shaft 24 is mounted to the support frame 8 using the mounting member 25. In the horizontal frame member 10b, the swing arm 22 is swingable in the front-rear direction by the pivot shaft 24 in the left-right direction.

The front end side of each of the swing arms 22 is fixed to the left and right side faces of the pillow member 17, and the swing arm 22 supports the pillow member 17 on the right and left sides. Further, the swing arm 22 in the longitudinal direction of the swing arm 22 means that the swing arm 22 between the pivot shaft 24 and the pillow member 17 is bent in a substantially S-shape. Further, each of the swing arms 22 extends rearward from the pivot shaft 24 . The left swing arm 22 and the right swing arm 22 are different from each other in a portion rearward of the pivot shaft 24.

That is, the portion (rear end portion) rearward of the pivot shaft 24 of the right swing arm 22 is bent at the outer side (right side) of the back rail 7 in the width direction later, and extends to the right after the bending. And terminates at a position beyond the right back rail 7. On the other hand, the portion (rear end portion) rearward of the pivot shaft 24 of the left swing arm 22 is bent toward the outer side (left side) of the back rail 7 in the width direction, and extends to the left after the bending. And after being bent a plurality of times beyond the position of the left side back rail 7, it is terminated slightly above the pivot shaft 24. Further, the above-described potential energy imparting member 23 is attached to the end portion of the left swing arm 22.

The potential energy imparting member 23 is a member that is attached to the end portion of the left side swing arm 22 (the base end side located further rearward than the pivot shaft 24), thereby imparting potential energy to the swing arm 22 in the forward swing direction. Specifically, the potential energy imparting member 23 of the chair type massage machine 1 of the present embodiment is a spring provided between the end portion of the left swing arm 22 and the backrest portion 3 (the rear side cover covering the backrest portion 3). Composition. The spring (potential energy imparting member 23) is configured to generate a potential energy imparting force A such that the end portion of the swing arm 22 is pulled upward, and the front end side of the swing arm 22 that extends forwardly of the pivot shaft 24 is forwardly forward. The direction of the swing gives potential energy.

In the above-described extension means 20, the potential energy imparting member 23 generates the potential energy imparting force A so as to pull the end portion of the swing arm 22 upward, and the swing arm 22 swings forward around the pivot shaft 24. The pillow member 17 supporting the front end of the swing arm 22 is projected forward.

On the other hand, the chair type massage machine 1 of the present embodiment is provided with a pulling back means 21 (retracting means) for pulling back the pillow member 17 projecting forward by the extension means 20. Specifically, the pulling means 21 is configured such that when the back massage mechanism 6 moves downward, the elastic member 26 provided on the back surface portion of the back massage mechanism 6 abuts on the elastic piece 27 provided on the swing arm 22, The swing arm 22 is pushed back in the opposite direction (backward, in other words, toward the back) in the opposite direction to the front.

Specifically, the upper elastic member 26 is an angular rod-shaped member that is attached to the right side of the back massage mechanism 6 and that extends in the longitudinal direction of the backrest portion 3. The upper elastic member 26 is configured to be attached to the slightly left side of the right back rail 7, and the rear end surface abuts against the upper elastic piece 27 of the swing arm 22. Further, the upper elastic piece 27 is a member provided on the slightly front side (the pillow member 17 side) of the pivot shaft 24 of the right swing arm 22, and is permeable to the left side (inward in the width direction) to abut against the back massage mechanism 6 The rear end face of the upper member 26. In other words, the rear end surface of the upper elastic member 26 is formed as a vertical surface that is steep in the vertical direction, and is curved forward as it goes toward the upper side, and has a sled shape when viewed from the rear. When the back massage mechanism 6 is moved upward, the upper elastic piece 27 can be slid downward along the curved rear end surface.

Therefore, in the above-described pulling back means 21, when the back massage mechanism 6 is moved upward, the upper side of the back massage mechanism 6 is placed on the upper side. The member 26 abuts against the upper elastic piece 27 of the right swing arm 22. When the back massage mechanism 6 is moved upward, the upper elastic piece 27 of the swing arm 22 moves upward along the curved rear end surface, and the position at which the upper elastic piece 27 and the upper elastic member 26 abut is moved to the rear, and is moved upward. The upper projecting member 26 pushes the swing arm 22 in a direction opposite to the direction in which the potential energy is given to the force A (backward, in other words, toward the inside of the back). As a result, in the pulling back means 21, the pillow member 17 which is extended forward by the extension means 20 can be pulled back.

Further, in order to prevent the pillow member 17 that has protruded forward from swinging downward, it is suspended downward, and in order to securely fix it to its position, a positioning means 28 for positioning the pillow member 17 at the extended position may be provided. As shown by the two-dot chain line in FIG. 2, such a positioning means 28 may be a belt or the like that connects the pillow member 17 and the back frame 10. By providing such a strap, the pillow member 17 can be positioned in the extended position.

Further, when the swing arm 22 is swung forward, the mounting member 25 used when the pivot shaft 24 is attached to the lateral frame member 10b may be provided at a position abutting on the swing arm 22 that has been swung forward. In this manner, the swing arm 22 that has been swung forward can abut the mounting member 25 and position the pillow member 17 in the extended position. That is, in this case, the mounting member 25 functions as a positioning means 28 for positioning the pillow member 17 at the extended position.

Next, an operation of extending the pillow member 17 by the above-described extension means 20 and an operation of pulling the pillow member 17 back to the rear by the pulling back 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 portion 3), the pillow member 17 is pulled back to the rear (that is, in the backrest portion 3).

That is, in the back massage mechanism 6 shown in Fig. 5, the upper elastic piece 27 of the right swing arm 22 abuts on the lower side of the rear end surface of the upper elastic member 26, and the swing arm 22 is oriented centering on the pivot shaft 24. The rearward pull back posture. Further, the swing arm 22 is provided so as to extend upward from the pivot shaft 24 in the vertical direction, and the pillow member 17 is positioned slightly above the pivot shaft 24. That is, the pillow member 17 of FIG. 5 is located further rearward than the back rail 7. If the pillow member 17 is positioned further rearward than the guide rail 7, the pillow member 17 does not become an obstacle to the vertical movement of the back massage mechanism 6, and the back massage mechanism 6 can be smoothly moved up and down.

When the back massage mechanism 6 shown in FIG. 5 is moved downward along the back rail 7 (when the back massage mechanism 6 is moved to a position away from the user's head), the upper elastic piece 27 and the upper elastic member 26 are flanked by one end side. The upper elastic member 26 is lowered downward while maintaining the sliding state. Later, the upper elastic piece 27 is located at a curved rear end surface (curved surface) formed on the upper side of the upper elastic member 26. Then, as shown in Fig. 4, the contact position of the upper elastic piece 27 with respect to the rear end surface of the upper elastic member 26 is shifted to the front, and the swing arm 22 is pivoted slightly forward about the pivot shaft 24.

That is, in the back massage mechanism 6 shown in Fig. 4, in conjunction with the downward movement of the upper elastic member 26, the swing arm 22 is swung forward. Therefore, by the potential energy imparting member 23 of the extending means 20, the front end side of the swing arm 22 is swung forward around the pivot shaft 24, and the pillow member 17 is extended further forward than the position shown in FIG.

Later, when the back massage mechanism 6 is further moved downward along the back rail 7, the upper end edge of the upper elastic member 26 is moved downward more than the upper elastic piece 27, so that the upper elastic piece 27 does not contact the rear end surface of the upper elastic member 26. .

Thus, as shown in FIG. 3, the swing arm 22 is further swung forward about the pivot shaft 24, so that the pillow member 17 supported at the front end of the swing arm 22 projects forward of the pivot shaft 24.

Further, in the above-described operations of Figs. 5 to 3, when the pillow member 17 is extended, when the pillow member 17 is pulled back, the reverse order is performed by the extension (Fig. 3 → Fig. 4 → Fig. 3) 5), the pillow member 17 that protrudes to the front can be pulled back to the rear.

In the chair type massage machine 1 of the present embodiment, even when the back massage mechanism 6 is moved from the head to the lower position by using the elevating mechanism 18, the pillow member 17 can be extended to the position after the back massage mechanism 6 is moved. The pillow member 17 supports the user's head.
