The massage unit of the present invention has a first link (41) having a protrusion (45) touching the back side of the shoulder (71) of the user (7) on the downward tip side, and the shoulder (the user of the user 7 on the downward tip side). 2nd link 42 which has the projection part 46 which touches the chest side of 71, and the 3rd and 3rd which axially supported and connected the proximal side rather than each protrusion 45 and 46 of the 1st, 2nd link. Four links 43 and 44, and the length L1 between the axis 43a and 44a on the first link 41 of the third and fourth links 43 and 44 is the second link 42. The four-section link 4 larger than the length L2 between the shafts 43b and 44b and the four-section link 4 are connected to the projection 45 of the first link 41. The drive section 3 which applies a force in the direction which pushes the shoulder 71 of the user 7, and the reverse direction to the center of the four link | links is provided centrally.

The chair-type massager of the present invention is provided with the above massage unit on the upper back 11 of the chair.

The operation of the present invention will be described below.

When the back side of the shoulder 71 of the user 7 pushes the protrusion 45 of the first link 41, the four-section link 4 deforms and the protrusion 45 is in a stable position. ) Is also approximately determined.

When the four-way link 4 receives the force in the direction of pressing the shoulder 71 of the user 7 by the driving means 3, the four-way link 4 moves toward the chest side of the shoulder about the protrusion 45. do.

From the projection 46 on the second link 42, the distance from the projection 45 on the first link 41 to the axis 43a of the third link 43 The distance L4 to the axis 43b of the three links 43 is large, and the length L1 between the axis 43a and 44a is the third link 43 on the second link 42. ) And larger than the length L2 between the respective shafts 43b and 44b of the fourth link 44, the tip of the second link 42 is the first when the four-link link 4 moves to the chest side. It moves while being deformed to approach the tip of the link 41.

As a result, an operation of massaging the shoulder 71 is performed by the protrusion 45 at the tip of the first link 41 and the protrusion 46 at the tip of the second link 42.

If the four-way link 4 is pulled in the direction away from the shoulder 71 by the drive means 3, the four-way link 4 is centered around the protrusion 45 touching the shoulder 71. Returns to the initial state pressed by the shoulder, and the tip of the second link 42 is separated from the first link 41 to open the state in which the shoulder 71 is pinched by the protrusion 45 and the protrusion 46. do.

During operation of the drive means 3, the sticking of the shoulders 71 by the protrusions 45 of the first link 41 and the protrusions 46 of the second link 42 and the loosening of the sticks are alternately performed. , Put on the massage will be executed.

The position of the projection 45 of the first link 41, which is the starting point of the pinching operation, is determined by the pushing force of the shoulder 71 of the user 7 with respect to the projection 45, and the driving means ( The trajectory of the massage motion is not constant, and the trajectory of the massage motion is not constant. A massage operation corresponding to the pushing force of the shoulder 71 of the user 7 with respect to the protrusion 45 of 41 is realized.

Moreover, compared with the constant track | orbit of a conventional massage motion | movement, the mating feeling with respect to the shoulder 71 of the protrusion parts 45 and 46 is also excellent.

In addition, since the four-segment link 4 can remove the pushing force of the shoulder 71 against the protrusion 45 of the first link 41, the four-segment link 4 itself can be freely deformed. 2) moves forward with respect to the projection 45, the second link 42 on the front side can freely move upward to open the user 7.

As a result, when the user 7 is separated from the massage unit 2, the presence of the second link 42 is not disturbed.

The pillow 6 protrudes toward the front in the center of the base 21, and the gear case 22 is provided in the rear part.

As shown in FIG. 6, the gear case 22 accommodates a worm 32 and a gear 33 that meshes with and engages the worm 32. The eccentric is provided to protrude in an eccentric position on both sides of the gear 33. The rotary shafts 34 and 34 penetrate the gear case 22 and protrude horizontally to both sides.

The following members provided on the eccentric rotation shaft 34 are provided on the left and right eccentric rotation shafts 34 and 34 in symmetrical directions, and only one eccentric rotation shaft 34 will be described below for convenience of explanation.

As shown to FIG. 5, FIG. 7, the upper base end of the arm 35 is axially supported by the eccentric rotation shaft 34, and in-plane parallel to the rotational movement surface of the arm 35 at the lower end of the arm 35. As shown to FIG. Install the four-section link (4) so that it can be deformed.

The four-section link (4) is a first link (41) having a projection (45) that touches the back side of the shoulder 71 of the user (7) on the free end side downward, the user 7 on the downward end side 2nd link 42 which has the projection 46 contacting the chest side of the shoulder 71, and proximal end side rather than each protrusion 45 and 46 of the 1st, 2nd link, The third link 43, which is composed of the third and fourth links 43 and 44, and is positioned below the fourth link 44, integrally protrudes forward at a substantially right angle from the downward tip of the arm 35. It is installed.

The length L1 between the axes 43a and 44a on the first link 41 of the third and fourth links 43 and 44 is between the axes 43b and 44b on the second link 42. It is larger than the length L2.

The length L4 from the shaft 43b for supporting the second link 42 and the third link 43 to the protrusion 46 of the second link 42 is the third link 43 and the first link. It is larger than the length L3 from the axis 43a for supporting the link 41 to the projection 45 of the first link 41.

The force of the second link 42 is applied in a direction in which the protrusion 46 of the second link 42 falls from the protrusion 45 of the first link 41 by the spring 47.

As shown in FIG. 4, the protrusion 45 of the first link 41 resembles the thumb of a human finger, and the protrusion 46 of the second link 42 has geothermal heat except for the thumb. Iii) is formed to have a transverse length than the protrusion 45 of the first link 41, and the protrusion 45, which resembles a thumb, is located inside the protrusion 46 which resembles other geothermal heat.

That is, the protrusion 45 resembling a thumb is located closer to the neck of the user 7 than the protrusion 46 resembling other geothermal heat.

As shown in FIG. 7, the arm 35 has the four-link | link | tip 4 by the eccentric rotation of the eccentric rotation shaft 34, maintaining the state in which the lower end of the arm 35 was inclined toward the inclination front. The restricting member 5 which regulates the inclination of the arm 35 is connected so that the downward pressure to the front of the furnace and the lifting operation upward to the rear of the inclined portion are performed.

The restricting member 5 of the embodiment is a link 51, and the link 51 axially supports the base end to the support plate 23 protruding downward from the gear case 22, and the upper end of the inclined front arm. It is axially supported and connected to the substantially center part of (35).

The arm 35, the motor 31, and the worm 32, the gear 33, and the eccentric rotation shaft 34, which link the arm 35 and the motor 31, perform a massage operation as described below. The drive means 3 is configured.

As shown in FIG. 7, in the unloaded state, the front end side of the first link 41 faces downward, and the front end of the second link 42 faces substantially forward.

In this state, when the user 7 sits on the chair and leans back, the back side of the shoulder 71 presses the projection 45 of the first link 41 to deform the four-section link 4.

Since the posture of the user 7 is restrained by the back 11, the position of the protrusion 45 is also approximately determined in a state where the position of the shoulder 71 is stabilized.

By the eccentric rotational shaft 34 of the drive means 3, the arm 35 repeatedly pushes the entire four-link 4 in the inclined downward direction, and vice versa.

When the four-link (4) receives the force in the direction of pressing the shoulder 71 of the user 7, the four-link (4) to the chest side of the shoulder centering on the projection 45 in the almost right position as described above Move.

From the projection 46 on the second link 42, the distance from the projection 45 on the first link 41 to the axis 43a of the third link 43 The distance L4 to the axis 43b of the three links 43 is large, and furthermore, the length L1 between the axis 43a and 44a is the third link 43 on the second link 42. ) And larger than the length L2 between the respective shafts 43b and 44b of the fourth link 44, the tip of the second link 42 is the first link when the four-link link 4 moves to the chest side. It moves while deforming so as to approach the tip of (41).

As a result, the shoulder 71 is massaged by the protrusion 45 at the tip of the first link 41 and the protrusion 46 at the tip of the second link 42 (see the change from the dashed line to the solid line in FIG. 8). Is executed.

The rotational movement amount of the protrusion 46 of the second link 42 is

(L1 / L2) × (L4 / L3) × [the amount of rotational movement of the axis with the third link 43 of the first link].

If the four-way link 4 is pulled in the direction away from the shoulder 71 by the drive means 3, the four-way link 4 is centered around the protrusion 45 touching the shoulder 71. Returns to the initial state pressed by the shoulder (a state indicated by the broken line in FIG. 8), and the tip of the second link 42 moves away from the first link 41, and is caused by the protrusions 45 and the protrusions 46. The feeling of the shoulder 71 is opened.

During operation of the drive means 3, the operation of fitting the shoulder 71 by the protrusion 45 of the first link 41 and the protrusion 46 of the second link 42 alternately with the opening of the fitting operation alternately. It will be executed, and the massage action will be performed.

As described above, in the embodiment, the protrusion 45 of the first link 41 resembles the thumb of a human finger, and the protrusion 46 of the second link 42 resembles geothermal heat except for the thumb. Since the protrusions 45 are formed wider than the protrusions 45 of the first link 41, and the protrusions 45 resembling the thumb are located closer to the neck of the user 7 than the protrusions 46 resembling geothermal heat, the user ( 7) can get a feeling of kneading with his hands on his back.

In the massage unit 2 of the present invention, the position of the projection 45 of the first link 41, which is the starting point of the pinching operation, depends on the pushing force of the shoulder 71 of the user 7 with respect to the projection 45. The trajectory of the massage operation is not constant, since the linkage 4 is deformed and converted without changing the force of the driving means 3 directly into the massage force. The massage motion corresponding to the posture or the pushing force of the shoulder 71 of the user 7 with respect to the protrusion 45 of the first link 41 is realized.

Moreover, compared with the constant track | orbit of a conventional massage motion | movement, the mating feeling with respect to the shoulder 71 of the protrusion parts 45 and 46 is also excellent.

In addition, since the four-segment link 4 releases the pushing force of the shoulder 71 against the protrusion 45 of the first link 41, the four-segment link 4 itself can be freely deformed. When 7) moves forward with respect to the projection 45, the second link 42 on the front side can be freely moved upwards, and the presence of the second link 42 allows the user 7 to have a massage unit ( There is nothing out of the way when falling from 2).

This invention is not limited to the structure of the said Example, For example, the massage unit 2 is not limited to providing the mechanism which pinches the right and left each by putting the pillow 6, but can be implemented only by one side. .

According to the present invention, the user 7 can obtain a feeling of kneading with his or her shoulder behind his back.

In addition, compared with the constant trajectory of the conventional massage operation, it is possible to provide a massage unit excellent in the fit of the shoulders 71 of the protrusions 45 and 46 and a chair type massager having the unit.
