In the right massage member 11, the arrangement of the members and the left massage member 10 are bilaterally symmetrical, but since they are the same as the left massage member 10, the description thereof is omitted.

The left massage member 10 includes a left arm member 15 (arm member) that protrudes from the base member 32 side of the massage device 1 toward the user side (toward the front). The projecting end (front end portion) of the left arm member 15 is protruded in two directions obliquely upward and obliquely downward, and a treatment member is provided on each of the front end portion of the upper side and the front end portion of the lower side (the upper left treatment member 91) And the lower left treatment member 92). Further, the right massage member 11 has the same structure as the left massage member 10.

That is, if the left arm member 15 and the right arm member 16 are brought close to each other, the upper left treatment member 91 of the left arm member 15 and the upper right treatment member 93 of the right arm member 16 are moved away in the left-right direction, and the left lower treatment portion of the left arm member 15 is treated. The lower right treatment member 94 of the member 92 and the right arm member 16 is moved away from each other in the left-right direction, and the treatment portion on the back side is sandwiched between the upper treatment members 91 and 93 and the lower treatment members 92 and 94 on the lower side.揉 Press the massage.

As shown in FIGS. 1 and 2, the left arm member 15 (arm member) is formed in a substantially boomerang shape in a side view (when viewed from the left side). Specifically, the left arm member 15 is a vertically long plate-shaped member that is curved toward the rear in the middle of the vertical direction. The shape in which the upper end side is inclined upward as compared with the middle side in the up-and-down direction, and the lower end side protrudes obliquely downward toward the front side.

Further, the left arm member 15 is formed in a side view in which the midway side in the vertical direction protrudes rearward from the upper end side and the lower end side, and the left arm member 15 penetrates in the left-right direction on the middle side of the wide width. In the manner, the insertion hole 18 through which the first rotating shaft 17 (details will be described later) is inserted is formed. In addition, the left arm member 15 has a shape in which the upper end protrudes obliquely upward toward the front side and the lower end protrudes obliquely downward toward the front side with respect to the middle side. Further, a treatment member 91 is provided at the upper end of the left arm member 15, and a treatment member 92 is also provided at the lower end of the left arm member 15.

An insertion hole 18 is formed in the middle of the left and right direction of the left arm member 15 . The respective insertion holes 18 are formed so as to penetrate the respective arm members 15 in the left-right direction, and are opened in a substantially circular shape on both the left side surface and the right side surface, and the first rotating shaft 17 and the tilt described later can be inserted therein. Rotating member 20.

On the other hand, the first shaft body 22 is provided at the front end portion and the lower end portion of the upper side of the left arm member 15, respectively. The first shaft body 22 is a columnar rod, and one of each of the front end portions of the left arm member 15 is provided in the protruding direction.

Specifically, as shown in FIGS. 1 and 2 , the first shaft body 22 protrudes outward from the protruding end of the left arm member 15 in the same direction as the protruding direction of the left arm member 15 . For example, in the case of the first shaft body 22 on the upper left side, since the upper end portion of the left arm member 15 extends obliquely from the midway side toward the front side, it is in the same direction as the protruding direction of the left arm portion 15 (from The rear lower side is disposed in an oblique direction toward the upper front side). The second shaft member 23 is provided on the outer circumference of the first shaft body 22.

The second shaft member 23 has a cylindrical body 23a that covers the first shaft body 22, and a direction that is substantially orthogonal to the axial direction of the first shaft body 22 in the longitudinal direction of the cylindrical body 23a. The second shaft body 23b formed in a state in which the first shaft body 22 penetrates.

The second shaft member 23 is a member having a side as a cross, and the cylindrical body 23a is externally inserted into the first shaft body 22, and is rotatably attached around the axis of the first shaft body 22 via a fastener. In other words, when the cylindrical body 23a rotates around the axis of the first shaft body 22, the second shaft member 23b rotates around the axis of the first shaft body 22, and the second shaft body 23b faces and The axis of the cylindrical body 23a is substantially orthogonal to the axis.

Further, on the rear end surface of each arm member 15, a regulating pin 21 for restricting the following rotation of each arm member 15 is provided. The first rotating shaft 17, the inclined rotating member 20, and the regulating pin 21 will be described in detail later.

Further, two treatment members 91, 92 are provided on the left arm member 15.

These treatment members 91, 92 are the distal end portions of the left arm member 15, and are rotatable around the axis of the extension line L extending along the protruding direction of the left arm member 15, and are wound in a direction substantially orthogonal to the extension line L. The shaft is rotatably mounted.

Specifically, as shown in FIGS. 3 to 6, the treatment members 91, 92 are provided at both front end portions (upper end portion and lower end portion) of the left arm member 15, and each of the treatment members 91, 92 is along the left arm member 15. The extension line L in which the protruding direction extends is disposed so as to penetrate the insides of the therapeutic members 91 and 92, respectively.

The front end portion of the left arm member 15 is provided with a first shaft body 22 that protrudes toward the front end portion, and has a shape that is substantially orthogonal to the axis (extension line L) of the first shaft body 22 The second of the second shaft body 23b is provided The shaft member 23 has the treatment members 91 and 92 attached to the second shaft body 23b so as to sandwich the respective first shaft bodies 22. In other words, the treatment members 91 and 92 are rotatably attached to the second shaft body 23b so that the centers of rotation of the treatment members 91 and 92 coincide with the axis of the second shaft body 23b. Further, the second shaft body 23b also rotates around the axis of the first shaft body 22. Therefore, these treatment members 91, 92 rotate about the axis of the first shaft body 22 of the left arm member 15, and rotate around the axis of the second shaft body 23b. That is, the treatment members 91, 92 are three-dimensionally rotated in such a manner that the spherical body rolls around the two rotational axes.

Further, the treatment members 91 and 92 are a group of members that divide a sphere, an ellipsoid or the like into two hemispherical shapes (convex shapes), and are formed of an elastic material such as hard rubber. The treatment members 91 and 92 are attached to the second shaft body 23b via the fasteners so as to penetrate the cylindrical body 23a via the fastener so that the second shaft body 23b penetrates from the tip end toward the center of the cross section.

For example, in the case of the left upper treatment member 91, the first shaft body 22 is rotatably attached around the axis of the first shaft body 22 with the first shaft body 22 interposed therebetween, and the first shaft body 22 is left. The upper end surface of the arm member 15 is disposed to extend obliquely upward toward the front side.

In other words, each of the treatment members 91 to 94 including the above-described one set of upper left treatment members 91 can be disposed at a position such that the extension line L is extended from each of the arm members 15 and 16 along the protruding direction of each of the arm members 15 and 16. The protruding end extends, and the extension line L penetrates the inside of the treatment members 91 to 94.

These treatment members 91, 92 rotate around the first shaft body 22 (in other words, around the axis of the cylindrical body 23a), and are freely rotatable about the axis of the second shaft body 23b. That is, a set of hemispherical members of the treatment members 91, 92 are integrated and wound. The axis of the first shaft body 22 rotates, and each hemisphere rotates around the axis of the second shaft body 23b.

For example, when the upper left treatment member 91 is rotated about the axis of the first shaft body 22, the left upper treatment member 91 is rotated in a direction substantially parallel to the direction in which the left arm member 15 is close to and away from the left arm member 15. At the same time, when the left upper treatment member 91 is rotated about the axis of the second shaft body 23b, the upper left treatment member 91 rotates in a direction (up-and-down direction) that intersects with the direction in which the left arm member 15 approaches.

Further, the treatment members 91 and 92 can simultaneously perform two rotations about the axis of the first shaft body 22 and the axis around the second shaft body 23b, and can also be wound around the axis or the circumference of the first shaft body 22. The axes of the two shaft bodies 23b are independently rotated.

As described above, the treatment members 91 to 94 that are rotatable around the two axial centers of the first shaft body 22 and the second shaft body 23b are, for example, on the massage mechanism 12, and the upper and lower treatment portions of the back and the like are up and down. When the massage operation is applied in the direction of movement, if the arm members 15 and 16 are swung in the vertical direction while moving in the vertical direction, as shown in FIG. 3, the treatment members 91 to 94 mainly surround the second shaft body. 23b rotates. Therefore, it is possible to reliably prevent the treatment members 91 to 94 from rubbing against the cover provided between the treatment members 91 to 94 and the user by the up and down rotation of the treatment members 91 to 94, thereby causing a malfunction of the cover.

Further, for example, when the massage mechanism 12 stops at a predetermined treatment portion such as the waist and applies a massage operation to the treatment portion, if the arm members 15 and 16 swing toward each other, as shown in FIG. The shaft body 23b is rotated around the first shaft body 22, whereby the treatment members 91 to 94 are mainly wound around The 1 axle body 22 rotates. Therefore, the left and right rotation of the treatment members 91 to 94 can reliably prevent the treatment members 91 to 94 from acting on the left and right sides of the cover between the treatment members 91 to 94 and the user, thereby causing damage to the cover.

In addition, since the treatment members 91 to 94 can be rotated in the up-and-down direction and the left-right direction as in the case of the "roller", the massage members 91 to 94 can be massaged while rotating along the surface of the treatment portion. The user is given a different massage feeling than the massage that pushes the treatment members 91 to 94 alone.

Next, the massage mechanism 12 that swings the above-described treatment member or massage member 10 will be described.

Further, in such a massage mechanism 12, various drive mechanisms or power transmission mechanisms can be employed. In the following, as an example of the massage mechanism 12, the massage device 1 of the present invention will be described by taking a mechanism in which the rotational driving force generated by the motor 24 or the knock motor 33 is converted into a rubbing operation or a tapping motion.

The massaging mechanism 12 includes a squeezing driving unit that causes the left and right massage members 10 and 11 to perform a squeezing operation, a tapping driving unit that causes a tapping operation on the right and left massage members 10 and 11, and a massage device 1 (left and right massage) The members 10 and 11 and the driving unit and the striking driving unit are movable up and down mechanisms 5 that are movable in the vertical direction in the backrest unit 4.

The driving portion is a portion that massages the treatment portion by moving the distal end portion away from the proximal end portion of each of the arm members 15 and 16 in the left-right direction, so that the proximal end portions of the arm members 15 and 16 are left and right. The structure of the swing of the direction to swing the front end portion.

Specifically, the click driving unit is provided to each of the massage members 10 described above. The insertion opening holes 18 and 19 of the 11 are respectively inserted into the inclined rotating member 20. A first rotating shaft 17 that penetrates the tilting rotating member 20 in the axial direction is provided at the center of the tilting rotating member 20. Each of the first rotating shafts 17 passes through the left and right inclined rotating members 20 in a communicating state, and the axial center is placed on the base member 32 in the horizontal direction. The first rotating shaft 17 and the tilting rotating member 20 constitute a driving portion. . Further, the squeezing drive unit has a squeezing motor 24 that rotationally drives the first rotating shaft 17, and a rear portion provided to the massaging members 10 and 11, and restricts vibration of the arm members 15 and 16 in conjunction with the rotation of the first rotating shaft 17. Blocking mechanism 25.

The inclined rotating member 20 is a cylindrical member attached to the middle of the first rotating shaft 17 and has an outer diameter larger than the axial diameter of the first rotating shaft 17 . Further, the tilting rotary member 20 is attached coaxially with the first rotating shaft 17, and a stepped portion for mounting the bearing 27 is formed on the outer peripheral surface thereof. The step portion is inclined with respect to the axial center of the tilting rotary member 20, and is formed along a circular orbit around the shaft, and the arm members 15 and 16 are rotatably supported with respect to the tilting rotary member 20.

The first rotating shaft 17 is a shaft member that communicates the center of the insertion hole 18 of the left massage member 10 with the center of the insertion hole 19 of the right massage member 10 and extends in the left-right direction. The left and right end portions of the first rotating shaft 17 are rotatably supported by the base member 32 by bearings 28, respectively. Further, at the end portion on the right side of the first rotating shaft 17, a squeezing motor 24 that rotationally drives the first rotating shaft 17 about the axis in the left-right direction is provided.

Specifically, a power transmission member including a worm wheel is provided on a drive shaft of the ram motor 24, and the power transmission member is rotated by the cymbal motor 24, and the first rotary shaft 17 is rotationally driven.

The vibration preventing mechanism 25 is a mechanism for causing the left massage member 10 and the right massage member 11 not to rotate with the first rotating shaft 17, and is configured such that a ball joint or a universal joint is provided on the rear end side of each of the massage members 10 and 11, for example. A free joint 29 such as a joint is engaged to restrict the rotation (synchronous rotation) of each of the massage members 10, 11.

The vibration preventing mechanism 25 is configured to connect the massage members 10 and 11 to the second rotating shaft 31 of the striking driving unit via the link 30 of the tapping driving unit, which will be described later, to restrict the rotation. Specifically, on the rear end side of the arm members 15 and 16 of the massage members 10 and 11, a restriction pin 21 that protrudes rearward is provided. The front end (rear end) of the restricting pin 21 is rounded into a spherical shape, and the end portion of the spherical restricting pin 21 is engaged with the free joint 29 provided on the front end of the link 30 of the striking driving portion. The arm members 15 and 16 are slidably coupled to the striking drive unit in the front-rear direction, the left-right direction, and the up-and-down direction.

Therefore, when the first rotating shaft 17 rotates, even if the massage members 10 and 11 are rotated in accordance with the rotation, the arm members 15 and 16 of the massage members 10 and 11 are held by the vibration preventing mechanism 25 not to be the first. The rotating shaft 17 is in a state of rotation.

The tapping drive unit includes a second rotating shaft 31 that is disposed in the horizontal direction so as to be parallel to the upper portion of the first rotating shaft 17, and a knocking motor 33 that rotationally drives the second rotating shaft 31.

Specifically, the drive shaft of the striking motor 33 is connected to the gear 34 provided at the center portion of the second rotating shaft 31 in the left-right direction. When the striking motor 33 is rotationally driven, the rotational driving force of the motor is transmitted via the gear 34. The second rotating shaft 31 is transmitted, and the second rotating shaft 31 can be driven. In addition, in A bearing 35 is provided outside the gear 34 on the second rotating shaft 31, and the second rotating shaft 31 is rotatable about the axis in the left-right direction via the bearing 35. Further, the second rotating shaft 31 on the outer side of the bearing 35 is provided with left and right eccentric driving bodies 36 which are eccentrically disposed with respect to the second rotating shaft 31 by a phase difference of 180°, and the left and right eccentric driving bodies 36 are provided. A link 30 (crankshaft) is disposed downward.

The eccentric drive body 36 does not coincide with the axial center of the second rotating shaft 31. When the hammer motor 33 is driven, the eccentric drive body 36 is eccentrically rotated with respect to the axial center of the second rotating shaft 31. Further, the lower end portion of the link 30 is coupled to the intermediate side of the arm members 15 and 16 in the vertical direction (the insertion holes 18 and 19). Specifically, the restriction pin 21 provided on the intermediate side of the arm members 15 and 16 (the massage member 10) in the vertical direction is coupled to the lower end portion of the link 30 via the free joint 29, and the connection structure between the restriction pin 21 and the link 30 is provided. A vibration preventing mechanism 25 that uses the above-described free joint 29 is constructed.

Therefore, when the knocking motor 33 is driven, the eccentric driving body 36 is eccentrically rotated with respect to the axial center of the second rotating shaft 31, and the movement is received, and the link 30 is pushed and pulled in the vertical direction. As a result, the left and right arm members 15 and 16 slightly swing the mutual treatment members 91 to 94 around the first rotation shaft 17, and the treatment members 91 to 94 perform the striking operation. Further, since the left and right eccentric drive bodies 36 are eccentrically disposed with respect to the second rotation shaft 31 by a phase difference of 180°, the treatment members 91 and 92 of the left massage member 10 and the treatment members 93 and 94 of the right massage member 11 are left and right. The direction moves in the opposite direction, and the left massage member 10 and the right massage member 11 alternately perform a tapping motion.

In addition, since the left and right eccentric drive bodies 36 have a phase of 180° Since the difference is set, the wobble generated in the left and right arm members 15, 16 alternately occurs, but the movement of the treatment members 91 to 94 is not limited to the above motion.

Next, the base member 32 that supports the massage device 1 and the vertical movement mechanism 5 that moves the base member 32 up and down in the backrest portion 4 will be described.

A back frame is provided inside the backrest portion 4, and a vertical movement mechanism 5 is attached to the back frame. The vertical movement mechanism 5 includes a base member 32 provided with the massage mechanism 12, and a guide roller 38 that rotatably supports the rotation axis center to the left and right outside on the left and right sides of the upper and lower portions of the base member 32. . In addition to this, a pair of left and right guide rails 39 that engage the guide roller 38 to guide the movement in the vertical direction are provided. The guide rail 39 is fitted in the inside of the backrest portion 4 with the longitudinal direction directed upward and downward.

Further, a screw shaft 41 that can be rotationally driven by the elevation motor 40 is disposed between the two guide rails 39, and a nut member (not shown) that is screwed into the screw shaft 41 is incorporated in the base member 32. Therefore, if the threaded shaft 41 is rotationally driven by the action of the lift motor 40, the nut member restores the force in the rotational direction of the threaded shaft 41 to the force in the translational direction, so the massaging mechanism 12 together with the base member 32 is on the backrest portion 4 Move up and down.

Thereby, the user who sits on the seat portion 3 and presses the backrest against the backrest portion 4 moves the massage mechanism 12 up and down, and can receive massage in a wide range from the shoulder to the back and the waist.

Next, a method of performing massage using the above-described treatment members 91 to 94, the massage member 10, and the massage mechanism 12, in other words, the massage of the present invention Method, focus on 揉 press massage to explain.

When the massage is performed, the cymbal is first driven by the motor 24. In this manner, the first rotating shaft 17 connected to the ram motor 24 rotates about the axis in the left-right direction, and the tilting rotating member 20 coaxially attached to the first rotating shaft 17 also rotates about the axis in the left-right direction.

Then, in conjunction with the rotation of the tilting rotary member 20, the rotational driving force is also applied to the massage members 10, 11 about the axis in the left-right direction. Further, since the massage members 10 and 11 are attached to the step portion 26 formed in an inclined shape via the bearing 27 on the surface of the outer peripheral surface of the tilting rotary member 20, the massage members 10 and 11 are rotated about an axis inclined with respect to the axis in the left-right direction. Therefore, the massage member 10 is rotated about an axis that is inclined with respect to the left-right direction.

At this time, the arm members 15 and 16 are connected to the vibration preventing mechanism 25 of the free joint 29 of the link 30 by the regulating pin 21, and are swinged at a predetermined angle along the top, bottom, left and right, and front and rear sides on the front end side with reference to the proximal end side. . Therefore, the massage members 10, 11 do not rotate together with the tilting rotation member 20, and are allowed to move only in the direction of swinging in the left-right direction. As a result, the massage members 10 and 11 are swung left and right with respect to the distal end side with reference to the proximal end side.

For example, if the left massage member 10 moves the treatment member 91 to the right, the treatment member 92 moves to the left. At this time, the right massage member 11 moves the treatment member 93 to the left, and moves the treatment member 94 to the right. That is, the left and right treatment members 91, 93 are close to each other, and the left and right treatment members 92, 94 face away from each other.

On the other hand, if the left massage member 10 moves the treatment member 91 to the left, the treatment member 92 moves to the right. At this time, the right massage member 11 moves the treatment member 93 to the right to move the treatment member 94 to the left. That is, left and right The treatment members 91, 93 are facing away from each other, and the left and right treatment members 92, 94 are close to each other.

By repeating such a approaching and leaving operation, the treatment portion can be sandwiched between the treatment members 91 to 94, and the massage portion can be applied to the treatment portion.

Further, the four treatment members 91 to 94 are wound around the first shaft body 22 (the axis about the protruding direction of the arm members 15, 16) and the second shaft body 23b in a direction substantially orthogonal to the direction away from the direction of separation. That is, the sphere is rotated in a variety of rotation manners, so which of the treatment members 91 to 94 is easily rotated in the direction of the swinging motion of the arm members 15, 16, and the respective treatment members 91 to 94 are easily moved in the left-right direction. Therefore, the four treatment members 91 to 94 are easily rotated without performing a frictional action such as rubbing against a cover or the like. That is, the four treatment members 91 to 94 that are rotated around the first shaft body 22 and around the second shaft body 23b do not apply a load to the cover that is worn and damaged.

In addition, it is possible to provide a massage feeling or a squeaking feeling different from the case where the treatment portion is massaged by rubbing with a non-rotating treatment member, and it is possible to provide a complicated and uncomfortable feeling of "squeaky feeling".

Further, since the treatment members 91 to 94 that can rotate like the "rollers" in the vertical direction and the left-right direction reciprocate, the respective treatment members 91 to 94 do not strongly rub the treatment portion that is raised on the body surface. Therefore, it is also possible to always bring a comfortable "squeaky feeling" to the treatment portion.

In addition, the embodiments disclosed herein are illustrative in all aspects and should not be considered as limiting. The scope of the present invention is defined by the scope of the claims and the scope of the claims.

In the above-described embodiment, the "four-head type" in which the treatment members 91 to 94 are provided on the upper and lower sides of the pair of right and left arm members 15 and 16 is exemplified. However, the present invention is not limited to the arm member of this embodiment. The present invention can also be applied to a "two-head type" in which one treatment member is provided on each of the pair of left and right arm members 15 and 16.

Further, in the above embodiment, the treatment members 91 to 94 are members having a substantially spherical or ellipsoidal appearance, but the appearance of the treatment members 91 to 94 may be other shapes. For example, the treatment members 91 to 94 may be formed in a polygonal shape.

Further, in the above-described embodiment, the first shaft body 22 and the second shaft member 23 are separately formed. However, all of these members may be integrally formed.
