And can be swung around an axis facing in the left-right direction. Further, the tip of the claw member 18 is biased toward the fan member 16, and the tip of the claw member 18 is pressed against the outer peripheral edge of the fan member 16 with a constant force.

The front end portion of the claw member 18 is formed in the shape of a hook with a barb, and the arm massage portion 5 is restrained by swinging the front end of the locking member 24 with a weak urging force to restrict the upward swing of the fan member 16. It can be locked so that it does not move upward.
Next, the mechanism for swinging the arm massage part 5 and the operation of the positioning means 13 will be described.
FIG. 3 shows a cross section of the armrest portion 3 when the arm massage portion 5 is in the retracted position.

As shown in FIG. 3, in the retracted position, the arm massage part 5 is stored inside the armrest part 3, and the upper surface of the arm massage part 5 and the upper surface of the armrest part 3 are flush with each other. It is easy to place an arm on the portion 3 and to extend the arm on the arm.
Further, the arm massage part 5 is in a state of swinging to the lower limit around the pivotal support part 12, and the fan member 16 connected to the arm massage part 5 via the arm member 17 is also swinged downward most. It has become. In this state, the push-back piece 21 and the positioning recess 23 formed adjacent to the push-back piece 21 are located away from the claw member 18, and the claw member 18 is engaged with the positioning recess 23 and the push-back piece 21. Absent.

And since the locking member 24 attached to the surface of the fan member 16 is engaged with the front-end | tip part of the nail | claw member 18, the upward swing of the fan member 16 is controlled, Therefore The arm massage part 5 is from a retracted position. Never move. However, for example, when the arm massage part 5 is pulled upward with a certain level of force, the locking member 24 and the claw member 18 are disengaged, and the fan member 16 is swung upward (in the clockwise direction in the illustrated example). become able to.

When the arm massage part 5 is gripped and swung upward, the fan member 16 connected to the arm massage part 5 via the arm member 17 also swung upwards around the pivot shaft 19 and eventually the massage shown in FIG. The arm massage part 5 moves to the position.
In this retracted position, the side opening 8 of the arm massage portion 5 is closed by a side plate 25 (shielding plate) provided on the inner side in the width direction of the armrest portion 3, and communicates with the outside. Not done.

As shown in FIG. 4, in the massage position, the positioning recess 23 formed on the outer peripheral edge of the fan member 16 by the upward rotation of the fan member 16 around the pivot shaft 19 is at the same position as the claw member 18. Therefore, the distal end portion of the claw member 18 biased with respect to the base end portion is fitted into the positioning recess 23 and the downward swing of the fan member 16 is restricted. Therefore, the arm massage part 5 does not swing downward from this massage position, and the swing position of the arm massage part 5 can be once positioned at the massage position.

In this massage position, the side opening 8 of the arm massage part 5 is located above the side plate 25 provided on the inner side in the width direction of the armrest part 3, and the user U can use the side openings 8 to 7 ( An arm can be inserted through the rear opening 7).
As shown in FIG. 5, when the arm massage part 5 is grasped and swung further upward than the massage position, the fan member 16 rotates further about the pivot shaft 19 and the tip of the claw member 18 is It becomes the same position as the push-back piece 21. Then, the push-back surface 22 of the push-back piece 21 comes into contact with the tip of the claw member 18 to push back the tip of the claw member 18 in the direction opposite to the urging direction, and the engagement between the tip of the claw member 18 and the positioning recess 23. As a result, the fan member 16 can be swung downward again, and the arm massage portion 5 can be moved downward to return to the retracted position.

After the push-back surface 22 comes into contact with the tip of the claw member 18 and the tip of the claw member 18 is pushed back, the fan member 16 is moved downward because the tip of the claw member 18 is separated from the positioning recess 23. Even if it is swung, the tip of the claw member 18 does not fit into the positioning recess 23. Therefore, it is possible to move the arm massage part 5 downward from the position (release position) swung upward from the massage position to the retracted position at once.

The chair type massage machine 1 concerning this invention is not limited to said embodiment.
