[Function and Effect] When receiving a massage, the user (48) has the first projection (52) lightly touching the back side of the shoulder and the second projection (56) from the upper part of the shoulder to the chest side. The massage unit (20) is positioned so that the massage unit comes in contact with. In this state, the treatment body
When the (42) is reciprocated in a substantially vertical plane, the first protrusion (52)
While pressing the back side of the shoulder, the first elastic plate (54) is elastically deformed, displacing the second elastic plate (58) downward. Therefore,
While the second protrusion (56) presses the upper side of the shoulder, the second elastic plate (58)
Is elastically deformed, and the second protrusion (56) slides forward of the user's shoulder. As a result, the distance between the first protrusion (52) and the second protrusion (56) is relatively reduced, the pressure of the second protrusion (56) pressing the upper side of the shoulder increases, and the shoulder is rubbed. Such effects can be obtained. When the stimulation is too strong, the subject moves away from the shoulder slightly so that the first protrusion (5
2) can be removed from the shoulder. When the first protrusion (52) is separated from the shoulder,
Since the deformation of the first elastic plate (54) returns to the original state, the second elastic plate (58)
Is restored, and the pressure on the rear and upper sides of the shoulder is released.

The massage unit (20) of the present invention has a projection (52) (5
The fit of the shoulder (50) of 6) is also excellent.

A massage device (16) including a massage unit (20) of the present invention is placed on a floor or a bed, and the head of a user is placed on a headrest (26), and both shoulders (50) (50) ) Is applied to each of the projections (52) and (56), and the treatment body (42) is reciprocated, so that a massage of pinching the shoulder can be received.

Further, the massage device (16) of the present invention
By mounting on the upper part of the backrest (14) of the chair, it is possible to receive a massage of pinching the shoulder while sitting on the chair.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a chair-type massage machine (10) comprises a seat (12) on which a user sits and a backrest (14) formed upward from the seat. The massage device (16) is provided above the backrest (14). The massage device (16) includes a backrest (14) as shown in FIGS.
The massage unit (2) is attached to the mounting shaft (18)
0) The base (24) of (22) is fitted and the massage device
(16) is height-adjustable along the mounting shaft (18).

The massage device (16) has a headrest (26) projecting forward from a base (24).
A driving means (28) for driving the massage unit (20) is provided at the rear of the (24). As shown in FIG. 5, the drive means (28) is connected to a drive motor (30), and a worm (32) and a gear (34) meshing with the worm (32) are housed inside a gear case (36). The shafts (38) protruding from the eccentric positions on both surfaces of the gear (34) penetrate the gear case (36) and protrude horizontally on both sides. The massage units (20) and (22) are connected to the shafts (38) and (38), respectively, and the eccentric rotation of the shafts (38) and (38) drives the massage units (20) and (22). You. Since the massage units (20) and (22) are bilaterally symmetric, in the following, the massage unit (2
0) will be described.

As shown in FIGS. 3 and 4, the massage unit (20) pivotally supports the upper base end of the base link (40) on the shaft (38), and mounts the base on the lower end of the base link (40). Link (40)
The treatment body (42) is attached so as to be deformable in a plane parallel to the turning surface of the. A restricting member (44) for preventing whirling by the shaft (38) is connected to the base link (40). By means of the regulating member (44), the base link (40) is kept substantially in a state where the lower end is inclined obliquely forward, and the shaft (38)
Pressing the treatment body (42) forward and downward by the eccentric rotation of
The movement is restricted so that the upward pulling operation is performed obliquely rearward. The regulating member (44) of the embodiment is a link piece, and the link piece pivotally supports a base end of a support plate (46) protruding downward from the gear case (36), and has a tip obliquely forward and upward. Is pivotally connected near the distal end of the base link (40).

The treatment body (42) has a shoulder of the user (48) on the distal end side.
A first elastic plate having a first projection (52) which is on the back side of the (50)
(54), and a second elastic plate (56) having a second protrusion (56) on the distal side of the shoulder (50) of the user (48) facing forward from the first elastic plate (54). 58). The first elastic plate (54)
The proximal end is fixed to the distal end of the base link (40), and near the proximal end is a cushion portion for adjusting the pressing force on the user.
(60) is formed. The cushion part (60) can be formed by bending the vicinity of the base end of the first elastic plate (54).

The second elastic plate (58) protrudes forward from the distal end side of the cushion portion (60) of the first elastic plate (54). As shown in the figure, the distal end of the first elastic plate (54) and the proximal end of the second elastic plate (58) are overlapped and fixed, and the center of the second elastic plate (58) is bent forward. Is also good. In this case, the first protrusion (52) is actually formed on the second elastic plate (58), but in the present invention, the portion extending downward is formed by the first elastic plate (54) and the front portion. The portion extending to the second direction is a second elastic plate (58). As shown in FIGS. 3 and 4, the second elastic plate (58) has a shape in which the distal end side is slightly bent downward. As shown in FIG. 4, the degree of bending of the second elastic plate (58) is such that the distance a from the first protrusion (52) to the tip of the second protrusion (56) is equal to the first protrusion (56). It should be longer than the distance b from 52) to the approximate center of the second protrusion (56).

The shape of the first projection (52) is 15 mm to 5 mm in diameter.
A substantially hemispherical shape of 0 mm is effective in enhancing the massage effect on the user. Also, the second protrusion (56)
As will be described later, it is desirable that the lower surface side of the second elastic plate (58) has a flat plate shape extending from the base end to the distal end so as to operate to slide on the shoulder of the user.

When the user (48) sits on the chair and leans on the chair, the first projection (52) presses the rear part of the shoulder (50). Since the leaning posture of the user (48) is regulated by the backrest (14), the position of the first projection (52) is almost determined while the position of the shoulder (50) is stable.

The operation in which the base link (40) pushes the treatment body (42) as a whole diagonally downward and forward by the shaft (38) of the driving means (28) and the reverse operation are repeated. Treatment body (42) is shoulder (50)
When the force in the pressing direction is applied, the cushion portion (60) is elastically deformed, and pushes out the first elastic plate (54) while slightly tilting the first elastic plate (54) as shown by the dotted line in FIG. 52) Shoulder (50)
Is pressed diagonally downward and forward. Due to the deformation of the first elastic plate (54), the second elastic plate (58) is pushed obliquely downward and forward, and the second protrusion (56) receives the elastic force of the second elastic plate (58), and Glide forward while pressing the upper side. At this time,
As shown in FIG. 4, the first protrusion (52) and the second protrusion (56)
There is a relationship of a> b in the distance between the protrusions, and the pressing force on the upper part of the shoulder by the second protrusion (56) increases. Further, when the shaft (38) is eccentrically rotated and the treatment body (42) is pulled obliquely upward and rearward, the pressing force on the shoulder (50) by the first protrusion (52) and the second protrusion (56) becomes It becomes smaller, and by repeating these operations, the operation becomes as if the user were rubbing their shoulders.

When the user moves his body forward during the massage, the pressing force of the first projection (52) is released, so that the treatment can be performed regardless of the rotation state of the base link (40). The body (42) returns to the state of FIG. 4 and releases the user from the state where the shoulder is pinched.

In the massage unit (20) of the present invention, the first projection (52) and the second projection (56) are formed on the elastic plates (54) and (58), respectively. ) (56) exerts a pressing force on the shoulder (50) depending on a pressing force of the user (48) on the first protrusion (52), and directly rubs the force of the driving means (28). The trajectory of the kneading operation is not constant because the cushion part (60) is transformed instead of being transformed into force. Therefore, the posture of the user (48) and the first protrusion of the first elastic plate (54)
The kneading operation according to the pressing force of the shoulder (50) of the user (48) against (52) can be realized. Massage unit of the present invention
The shoulder kneading massage according to (20) is superior in the fit of the protrusions (52) and (56) to the shoulder (50), as compared with the conventional kneading motion having a constant trajectory. If the treatment body (42) presses too hard on the shoulder and the user escapes, the second protrusion (56)
Moves in the direction away from the shoulder, so it is a displacement in the safe direction and easy to use.

The present invention is not limited to the configuration of the above-described embodiment. For example, the massage unit (20) is not limited to providing the right and left sandwiching mechanisms with the headrest (26) therebetween. It can be implemented alone.

The drive means (28) is not limited to the above embodiment as long as it is a mechanism for reciprocating the treatment body (42). In the reciprocating motion of the treatment body (42), it is not necessary for the outward path and the return path to draw the same trajectory, and the trajectory may be elliptical or circular as in the above embodiment.

Further, as shown in FIG. 1, a well-known kneading and hitting unit (72) having a mimetic ball (70) (70) at the center in the width direction of the backrest (14) can be moved up and down. It can also be deployed to provide massage combining the unit (72) and the massage unit (20) of the present invention.
