For the massage performed by the treatment element 2, either a hitting operation or a vibration operation can be selected.

The hitting operation is to push out only the right treatment element 2R toward the treatment unit side with the left treatment element 2L retracted, and then retract the right treatment element 2R and at the same time move only the left treatment element 2L to the treatment unit side. The operation of extruding toward is continuously repeated. If such a hitting operation is performed, the left and right treatment parts can be alternately pushed by the

extruded treatment elements

2L and 2R, and massage can be performed so as to strike the left and right treatment parts.

In addition, the vibration operation increases the pitch of hitting the left and right treatment parts with the

treatment elements

Moreover, the up-down direction in FIG. 3 is referred to as “front-rear direction” when the massage machine 1 is described. Furthermore, the paper surface penetration direction in FIG. 3 is referred to as “vertical direction” when the massage machine 1 is described. These directions are shown as appropriate in FIGS.
Hereinafter, details of the casing 3 provided in the massage machine 1 of the present invention and the massage mechanism 4 provided in the casing 3 will be described.

As shown in FIG. 1, the casing 3 is a bowl-shaped member whose inside is hollow so that the massage mechanism 4 can be accommodated, and is formed using synthetic resin, metal, or the like. The casing 3 has a configuration in which the front case 3F and the rear case 3B are combined in the front-rear direction, and the rear case 3B that opens toward the front and the front case 3F that opens toward the rear are combined. The inside is formed as a hollow body.

Further, a treatment opening 5 for arranging the treatment element 2 so as to protrude toward the user U side is formed on a surface (front surface) facing the front (treatment portion side) of the front case 3F. The treatment opening 5 is formed separately on the left side and the right side of the casing 3, and the left treatment element 2L is provided in the left treatment opening 5L, and the right treatment treatment is provided in the right treatment opening 5R. Each child 2R is arranged so as to protrude from the rear toward the front. Each of the

treatment openings

5L, 5R is formed in a substantially rectangular shape when viewed from the front, and is opened in a shape in which the outer edge is formed in a semicircular shape with respect to the inner edge in the width direction. In addition, the treatment element 2 that performs a hitting operation or a vibration operation is prevented from coming into contact.

Furthermore, a cushion material 6 such as urethane foam is provided around the casing 3 described above. The cushion material 6 is formed in a square shape having a size larger than that of the casing 3, and a concave portion 16 opened forward is formed on the front surface thereof. And the circumference | surroundings (up and down, right and left, and back) of the casing 3 are covered with the cushion material 6 so that the casing 3 may be inserted in this recessed part 16. FIG. Thus, if the circumference | surroundings of the casing 3 are covered with the cushioning material 6, even if a big force is applied from the outside, the casing 3 and the massage mechanism 4 are not easily damaged. Furthermore, a cloth cover is provided outside the cushion material 6.

Next, the massage mechanism 4 accommodated in the casing 3 described above will be described.
As shown in FIGS. 2 and 3, the massage mechanism 4 includes an electric motor 7, a rotating shaft 8, an eccentric rotating body 9, and a connecting arm 10, and is generated by the electric motor 7 using the eccentric rotating body 9. By converting the rotational movement of the rotary shaft 8 and moving the connecting arm 10 back and forth (back and forth movement), the treatment part 2 can be massaged with the treatment element 2 provided at the tip of the connecting arm 10. ing.

The electric motor 7 is a member that generates a rotational driving force on the rotary shaft 8 (drive shaft) arranged in the left-right direction, and outputs sufficient power to operate the left and

right treatment elements

2L, 2R to the rotary shaft 8. It can be provided, and is provided at substantially the center inside the casing 3. Specifically, one annular rubber member 11 for vibration suppression is provided on the left and right sides of the casing 3, and the electric motor 7 is connected to the casing 3 via the rubber member 11 for vibration suppression. I support it.

An attachment portion 13 for attaching an elastic support member 12 described later is provided on the front side of the housing of the electric motor 7. The attachment portion 13 is a portion in which a part of the casing of the electric motor 7 having a cylindrical shape extends forward, and the elastic support member 12 is connected to the front end thereof.
The rotating shaft 8 described above is a long bar-like member that is arranged with its axis oriented in the left-right direction. The above-described electric motor 7 is located in the midway portion of the rotating shaft 8 in the longitudinal direction. That is, the rotary shaft 8 includes a left rotary shaft 8L provided on the left side of the electric motor 7 and a right rotary shaft 8R provided on the right side of the electric motor 7 with the electric motor 7 as a reference. . A left eccentric rotating body 9L is provided at the tip (left end) of the left rotating shaft 8L, and a right eccentric rotating body 9R is provided at the tip (right end) of the right rotating shaft 8R.

The eccentric rotator 9 is a member (crank member) that converts the rotational motion of the rotational shaft 8 into the translational motion of the connecting arm 10, and is a disc-like shape provided so as to be perpendicular to the axial center of the rotational shaft 8. It is a member. The eccentric rotating body 9 provided in the massage machine 1 described above includes the left eccentric rotating body 9L provided at the left end of the left rotating shaft 8L and the right eccentric rotating body 9R provided at the right end of the right rotating shaft 8R. . These left and right eccentric rotating

bodies

9L and 9R are attached so as to be coaxial with the axis of the rotating shaft 8.

Specifically, the left end of the left rotating shaft 8L is inserted in the center of the right side surface of the left eccentric rotating body 9L, and the right end of the right rotating shaft 8R is inserted in the center of the left side surface of the right eccentric rotating body 9R. The left and right

eccentric rotators

9L and 9R have a line-symmetric structure with respect to the rotation shaft 8.
The rotational motion of the rotary shaft 8 is converted into the translational motion of the connecting arm 10 on the side surface where the rotary shaft 8 is not fitted, that is, on the left side surface of the left eccentric rotary body 9L and the right side surface of the right eccentric rotary body 9R. A connecting pin 14 is provided. The connecting pin 14 is attached at a position eccentric to the axis of the rotary shaft 8 on the side surface of the eccentric rotator 9, and is disposed at a position spaced from the axis of the rotary shaft 8. Therefore, when the eccentric rotator 9 is rotated, the connecting pin 14 moves along a trajectory that goes around the axis of the rotary shaft 8. Further, the base end side (rear end) of the connection arm 10 is also connected to the connection pin 14, and when the eccentric rotating body 9 is rotated, the base end side of the connection arm 10 is also the axis of the rotary shaft 8. Circulate around. That is, the eccentric rotator 9 functions as a crank that converts the rotational motion of the rotary shaft 8 into the translational motion of the connecting arm 10.

The connecting arm 10 is a long member that connects the eccentric rotator 9 and the treatment element 2, and one pair is provided on each of the left eccentric rotator 9L and the right eccentric rotator 9R. The base end side (rear end) of each connecting arm 10 is formed in a disc shape (disc shape in a side view) wider than the front end side (front end), and on the side surface facing the electric motor 7 side. The connection concave part into which the above-described connection pin 14 can be inserted is formed. Specifically, a connecting pin 14 is fitted into the connecting recess through a bearing 18, and the base end side of the connecting arm 10 is supported so as to be rotatable about an axis facing the left and right direction with respect to the connecting pin 14. ing. In other words, the connecting arm 10 functions as a camshaft that converts the rotational force of the eccentric rotating body 9 into a translational force by fitting the connecting pin 14 described above into the connecting recess.

The connecting arm 10 extends forward from the eccentric rotator 9 and then bends substantially at right angles toward the inner side in the left-right direction. The treatment element 2 and the elastic support member 12 are attached to the bent portion. It is attached.
The treatment element 2 is a member that performs a tapping massage and a vibration massage on the treatment part of the user U. The distal end (front end) of the treatment element 2 has a curved shape so as to bulge gently toward the front, and it is easy to exert the acupoint pushing effect by pushing the treatment portion with the gently bulged distal end. ing. The proximal end (rear end) of the treatment element 2 is fixed to the distal end side of the connecting arm 10 (a bent portion on the distal end side of the connecting arm 10) using a bolt or the like.

The elastic support member 12 is a member that connects the distal end side (front end side) of the connection arm 10 and the electric motor 7 (attachment portion 13), and the connection arm 10 rotates along with the rotation of the eccentric rotating body 9. Can be suppressed. In this embodiment, the elastic support member 12 is formed of a plate member made of rubber or the like, and is provided on the left and right respectively corresponding to the left connecting arm 10 and the right connecting arm 10.

For example, taking the left elastic support member 12 as an example, the elastic support member 12 is arranged along the vertical direction and the horizontal direction. The left end side of the elastic support member 12 is coupled to the distal end side of the coupling arm 10 (the distal end side of the coupling arm 10 positioned on the inner side in the width direction than the position where the treatment element 2 is attached). Further, the right end side of the elastic support member 12 is connected to the front wall portion of the electric motor 7 described above, and suppresses the connecting arm 10 from rotating together with the eccentric rotating body 9.

If the elastic support member 12 is formed of an elastic material such as rubber, the connecting arm 10 is allowed to move to some extent along the front-rear direction. However, on the other hand, the connecting arm 10 connected to the housing of the electric motor 7 by the elastic support member 12 does not rotate as the eccentric rotating body 9 rotates. For this reason, the elastic support member 12 causes the treatment element 2 attached to the front end of the connecting arm 10 to repeat forward and backward with the rotation of the eccentric rotating body 9. If such an elastically deformable elastic support member 12 is used, the structure of the massage mechanism 4 is simpler than that of providing a joint member or the like, and the apparatus configuration can be simplified.

By the way, in the massage machine 1 of this embodiment, the rotation phase of the right eccentric rotation body 9R attached to the right rotation shaft 8R and the rotation phase of the left eccentric rotation body 9L attached to the left rotation shaft 8L extending to the left side The point is that the phase is reversed. Specifically, this “reverse phase” refers to a case where there is a phase difference of 90 ° to 270 ° between the two

eccentric rotators

9L and 9R, and the connecting pin 14 of one eccentric rotator 9 And the position of the connecting pin 14 of the other eccentric rotating body 9 have a phase difference of 90 ° to 270 ° (preferably approximately 180 °).

For example, in the case of the eccentric rotators 9 in a “reverse phase” relationship, for example, when the connecting pin 14 of the left eccentric rotator 9L is positioned forward with respect to the axis of the left rotation shaft 8L, the right eccentric rotator The 9R connecting pin 14 is positioned rearward with respect to the axis of the right rotation shaft 8R.
The left and right eccentric rotating bodies 9 are also provided with balance weights 15. The balance weight 15 is attached to the opposite side of the eccentric rotating body 9 with respect to the above-described connecting pin 14 with respect to the axis of the rotating shaft 8 so that the rotational balance can be achieved when the eccentric rotating body 9 rotates. It has become. The balance weight 15 can suppress unnecessary vibrations generated in the eccentric rotating body 9, and can smoothly advance and retract the treatment element 2 back and forth to give the user U a comfortable tapping massage and vibration massage. Is possible.

As described above, in the eccentric rotating body 9 attached (aligned) in a reverse phase state, one of the left and

right treatment elements

2L, 2R protrudes forward, and the treatment element 2 can be waisted or the like. When the treatment part is being pressed (beating), the other treatment element 2 is retracted backward, and no massage operation is performed on the treatment part. Therefore, a reaction force is applied from the treatment part to one of the treatment elements 2 that protrudes forward and is subjected to a massage operation, but a reaction force is not applied to the other treatment element 2 that is not subjected to a massage operation from the treatment part.

When the eccentric rotating body 9 is further rotated, the other treatment element 2 protrudes forward to perform the massage operation, and the one treatment element 2 moves backward to stop the massage operation. That is, in the eccentric rotating body 9 attached in the reverse phase state, the left and

right treatment elements

2L and 2R are alternately moved back and forth, and the reaction force acts from the treatment portion each time, so the eccentricity attached in the same phase state. A large reaction force does not act at once from the left and

right treatment elements

2L, 2R unlike the rotating body 9, and the load on the rotating shaft 8 and the electric motor 7 can be reduced as much as possible.

Therefore, the massage machine 1 of the present invention provides a suitable tapping massage and vibration massage on both the shoulders and the waist of the user U while suppressing a large load from being applied to the electric motor 7 and the rotary shaft 8 at a time. It can be granted.
The method of massaging the user's U treatment part with the massage machine 1 mentioned above, in other words, the massage method of this invention is demonstrated.

First, electric power is supplied to the electric motor 7 to drive the rotary shaft 8 to rotate. Then, with the above-described configuration, the left and right eccentric rotating

bodies

9L and 9R also rotate around the axis according to the rotation of the rotating shaft 8. Specifically, when the left rotation shaft 8L is rotated, the left connecting pin 14L moves on the left side so as to circulate around the axis of the left rotation shaft 8L at a distance.
On the other hand, regarding the right eccentric rotator 9R, the position of the right connecting pin 14R on the right side surface of the right eccentric rotator 9R is not only the position eccentric from the axis of the right rotation shaft 8R, but also the left eccentric rotator. The phase is opposite to that of the 9L connecting pin 14L. Therefore, when the right rotation shaft 8R is rotated, the right connection pin 14R not only circulates around the axis of the right rotation shaft 8R on the right side surface as the left connection pin 14L, but the right connection pin 14R The left connection pin 14L also rotates with a phase difference of approximately 180 °.

Therefore, in the massage mechanism 4 described above, the left connecting pin 14L is positioned in front of the axis of the left rotating shaft 8L, and the right connecting pin 14R is positioned behind the axis of the right rotating shaft 8R. Become. In this state, the left connecting arm 10L is in a position protruding forward by the amount that the left connecting pin 14L has shifted forward, and the left treatment element 2L provided at the front end of the left connecting arm 10L is also forward. It will be the position that protrudes. On the other hand, the right connecting arm 10R is moved backward by the amount of the right connecting pin 14R moving backward, and the right treatment element 2R provided at the front end of the right connecting arm 10R is also moved backward. It becomes the position. Therefore, it becomes possible to push out only the left treatment element 2L toward the treatment part side with the right treatment element 2R retracted, and it becomes possible to massage the left treatment part with the left treatment element 2L. .

Further, when the electric motor 7 is rotated, the positional relationship between the left eccentric rotator 9L and the right eccentric rotator 9R is reversed, and only the right treatment element 2R is moved to the treatment unit side with the left treatment element 2L retracted. It becomes possible to extrude and massage the right treatment part with the right treatment element 2R.
In this way, by alternately massaging the treatment portion with the left and

right treatment elements

2L, 2R, it is possible to perform the hitting operation and the vibration operation described above.

In addition, the structure of the massage machine of this invention is not limited to the above-mentioned embodiment. In addition, in the embodiment disclosed this time, matters that are not explicitly described, for example, operating conditions and operating conditions, dimensions and weights of components, do not deviate from the range normally practiced by those skilled in the art.
