Are formed.

Further, one end of a cylindrical member 22 having a hollow portion 29 for accommodating the fixed gear 25 and the fixed shaft 26 is screwed to the upper end of each of the bases 21a and 21b. 22 is provided integrally with the base 21a or the base 21b.

The cylindrical members 22, 22 are provided eccentrically with respect to the extension of the center axis of the drive shaft 16,
The upper side protrudes from the opening 1a shown in FIG. 1 to the outside of the main body case 2 (see FIG. 1). At the other end of each of the cylindrical members 22, 22, an opening hole 29 a that opens the hollow portion 29 toward the other end of the cylindrical member 22 is formed.

A treatment element 10 made of elastic rubber (natural rubber, artificial rubber) or synthetic resin is mounted on the other end of each of the cylindrical members 22, 22 coaxially with the fixed shaft 26. The end face of each treatment element 10, 10 has an opening hole 29 in the center.
It has a convex curved surface having a through hole 34 having the same diameter as that of a. The opening hole 29a and the through hole 34 are coaxial with the fixed shaft 26, and their inner walls are substantially flush. In addition, each treatment child 1
0 and 10 may be formed integrally with the cylindrical member 22.

The other end of the drive shaft 16 is disposed in each hollow portion 29, 29, and the fixed gear 25 and the fixed shaft 26
And a plunger 27 made of synthetic resin.
(Corresponding to a rotating body) (see FIGS. 6 and 7).

At one end of each of the plungers 27, 27, an insertion hole 31 into which the fixed shaft 26 is inserted is formed. Each plunger 27, 27 is covered on the other end side of the fixed shaft 26, and the other end protrudes from the other end of the cylindrical member 22 from the hollow portion 29 through the opening hole 29a.

A spur gear meshing with the fixed gear 25 is formed on the outer peripheral surface of each plunger 27,27.
As a result, each plunger 27, 27
, And rotates about the fixed shaft 26 as the center of rotation when receiving the rotational force from the fixed gear 25.

Further, at the other end of each of the plungers 27, 27, a finger indenter 28 made of rubber or synthetic resin is mounted. Each of the acupressure elements 28, 28 is formed in a cap shape having an open end on one end side and an end face on the other end side formed in a convex curved surface, and is coaxially covered on the other end side of the plunger 27.
In addition, each acupressure element 28 may be formed integrally with the plunger 27.

Further, a cam groove 32 that contacts the pin 30 of the fixed shaft 26 is formed on the inner peripheral wall of the insertion hole 31 of each of the plungers 27, 27, and a cylindrical cam composed of the pin 30 and the cam groove 32 is formed. It is configured. The fixed shaft 2 is inserted so that the plunger 27 inserts the fixed shaft 26 into the insertion hole 31.
6, the pin 30 is inserted into the cam groove 32.

As shown in FIG. 7, the cam groove 32 is formed in a mountain shape (or V shape) having a height in the axial direction of the plunger 27 when the cam groove 32 is expanded.

Now, the case where the pin 30 is located in the cam groove 32 formed at the most other end side (upper side of the paper surface of FIG. 7) of the plunger 27 is assumed that the rotation angle of the plunger 27 is 0 °. Then, when the rotation angle is 0 °, the fixed shaft 26
Is inserted into the insertion hole 31 most deeply, and when the rotation angle of the plunger 27 is 180 °, the pin 30 is located at the lowermost side of the cam groove 32 and the fixed shaft 26 is inserted into the insertion hole 31.
Into the shallowest.

Accordingly, when each of the plungers 27, 27 is relatively rotated with respect to the fixed shaft 26, the cam groove 32 pushes the pin 30, and the pin 30 relatively slides along the cam groove 32. 27, 27 reciprocate in the axial direction of the fixed shaft 26. As a result, the acupressure element 28 attached to the other end of the plunger 27 is
4 advances and retreats in the axial direction of the fixed shaft 26.

That is, when the plungers 27 perform the forward movement (the rotation angle of the plunger 27 is changed from 0 ° to 180 °), the end surfaces of the acupressure elements 28, 28 are more outward than the end surface of the treatment element 10. To advance to In contrast, each plunger 27,
27 performs a backward movement (rotation angle 1 of plunger 27)
(80 ° → 0 °), the end faces of the acupressure elements 28, 28 retreat toward the end face side of the treatment element 10.

Then, the rotation angle of the plunger 27 is 0 °.
In this case, the end faces of the acupressure elements 28 and 28 are substantially flush with the end faces of the treatment element 10. As described above, the acupressure elements 28, 28 protrude and retract from the end face of the treatment element 10 by the rotation of the plunger 27.

Further, a spur gear 35 is formed on a side surface of each of the bases 21a and 21b.
Are intermeshed with each other. The gear ratio between the spur gears 35, 35 is 1: 1, and when one of the base 21a and the base 21b rotates, the other rotates in the opposite direction by the same amount in conjunction with the rotation.

Thus, the base 21a and the base 21
When b is arranged so as to be plane-symmetric with respect to the reference plane F, even if only one of the base 21a and the base 21b is applied with a rotational force, the other rotates in the opposite direction by the same amount. Therefore, the state where the massage mechanism 12 is plane-symmetric with respect to the reference plane F is maintained (corresponding to a maintaining means).

A disc-shaped stopper 33 made of rubber or synthetic resin is screwed to the upper surface of the gear box 15 (see FIG. 2). The center axis of the stopper 33 is arranged on the reference plane F, and is arranged at right angles to the center axis L of the worm gear 13. Side surface (peripheral surface) of stopper 33
Are in contact with the spur gear 35 formed on each of the bases 21a and 21b.

The stopper 33 has the following functions. That is, when the rotation direction of the motor 11 is switched from the reverse direction to the forward direction, each one-way clutch 19a, 1
9b and the drive shaft 16 may not be disengaged. In this case, even when the motor 11 is rotating in the forward direction, the respective bases 21a and 21b try to rotate integrally with the drive shaft 16.

At this time, the spur gear 35 formed on each of the bases 21a and 21b tries to rotate integrally with the drive shaft 16, but the rotation of the spur gear 35 is stopped by the stopper 33 which is in contact with the spur gear 35. Regulated by

The force by which the stopper 33 regulates the rotation of the spur gears 35, 35 is determined by the one-way clutches 19a, 19b.
Is set to be larger than the force for disengaging the drive shaft 16 from the drive shaft 16. Therefore, each one-way clutch 19a,
The engagement between the drive shaft 19b and the drive shaft 16 is released (the clutch is disengaged).

On the other hand, the stopper 33 is connected to each spur gear 3
When the motor 11 rotates in the reverse direction, the one-way clutches 19a, 19b
And the drive shaft 16 are set to be smaller than the force for engaging and rotating together. Therefore, each spur gear 35,
35 rotates while rubbing against the peripheral surface of the stopper 33.

As described above, the stopper 33 assists in releasing the engagement between the one-way clutches 19a and 19b and the drive shaft 16. When the rotation direction of the drive shaft 16 changes, each one-way clutch 19a, 19b and the drive shaft 16
The configuration of the stopper 33 is not limited as long as the engagement with the stopper 33 is surely released.

For example, the stopper 33 is configured to advance and retreat with respect to each of the spur gears 35 by a solenoid or an actuator. When the rotation direction of the motor 11 changes from the reverse direction to the forward direction, the stopper 33 moves Gear 3
5 and 35, by making contact with each other, each spur gear 3
When the rotation direction of the motor 11 is changed from the normal direction to the reverse direction,
The stopper 33 may be moved backward and away from each spur gear 35,35.

The above-described massage machine 1 operates by receiving power supply from a battery or a commercial power supply. When the massage machine 1 receives power supply from a commercial power supply,
The power switch 7 and the forward / reverse switch 8 shown in FIG.
It may be provided on a power supply line (cord) from a commercial power supply.

<Operation Example of Massage Machine> Next, an operation example of the above-described massage machine 1 will be described with reference to FIG. 3 and FIGS. 8 to 10 show the motor 1 shown in FIG.
Massage mechanism 12 when 1 rotates in the forward direction
11 to 14 are operation explanatory diagrams of the massage mechanism 12 when the motor 11 shown in FIG. 2 rotates in the reverse direction.

FIGS. 8 to 10A are plan views showing the configuration of the massage mechanism 12 shown in FIG. 3 on the right side of the reference plane F. FIGS. , Reference plane F
FIG. 2 is an end view of the configuration on the right side of the massage machine 1 as viewed from the back side.

The operation of the massage mechanism 12 is based on the reference plane F
Are mirror-symmetrical with respect to the reference plane F on the right and left sides of.
Therefore, the operation on the left is completely opposite to the operation on the right, so the operation on the right will be described as an example, and the operation on the left will be described as necessary.

In this example, as shown in FIG. 8, the drive shafts 16, 16 and the fixed shafts 26, 26 are arranged on a straight line perpendicular to the reference plane F, and the fixed shafts 26, 26 (acupressure 2
The rotation angle of the drive shaft 16 when the distance between (8, 28) is the longest is 0 °. When the rotation angle of the drive shaft 16 is 0 °, the pin 30 of each fixed shaft 26, 26 is located at the uppermost position of the cam groove 32, and each acupressure element 28, 28 is on the end face side of the treatment element 10. It is in the most retracted state (the rotation angle of the plunger 27 is 0 °: see FIG. 7). This state is referred to as an initial state (see FIGS. 8A and 8B).

In this initial state, it is assumed that the power switch 7 of the massage machine 1 is turned on with the forward / reverse switch 8 of the massage machine 1 shown in FIG. Then, the worm gear 13 rotates by the forward rotation of the motor 11, and the worm wheels 14, 14 rotate relatively. Thereby, each drive shaft 16, 16 rotates relatively.

At this time, the right drive shaft 16 rotates in the reverse direction and engages with the one-way clutch 19b. Thereby, the one-way clutch 19b (the bush 20),
Each component (the base 21b and the component on the base 21b) located on the other end side of the drive shaft 16 with respect to the bush 20 includes:
It rotates synchronously (integrally) with the drive shaft 16.

That is, the cylindrical member 22 on the right side of the reference plane F,
Treatment element 10, fixed shaft 26, plunger 27, acupressure element 28
Rotates counterclockwise around the drive shaft 16 while maintaining a constant distance from the drive shaft 16. On the other hand, the reference plane F
The right cylindrical member 22, the treatment element 10, the fixed shaft 26, the plunger 27, and the acupuncture member 28 rotate around the drive shaft 16 in the clockwise direction while maintaining a constant distance from the drive shaft 16.

Specifically, when the rotation angle of the drive shaft 16 is 90
°, the fixed shaft 26 rotates 90 ° from the initial state.
When the rotation angle of the drive shaft 16 becomes 180 ° (see FIG. 9), the fixed shaft 26 rotates 180 ° from the initial state (FIG. 1).
0). Thereafter, when each of the drive shafts 16 and 16 rotates by 360 °, the massage mechanism 12 returns to the above-described initial state.

In the above operation, the one-way clutch 1
When the drive shaft 16 is engaged with the drive shaft 9a (19b), the plungers 27, 27 rotate integrally with the base 21a (21b). That is, the driving force of the driving shaft 16 is
It is transmitted to 1a, 21b, and is not transmitted to each plunger 27, 27 as a rotating body.

On the other hand, in the initial state of the massage mechanism 12 (see FIG. 8B), when the forward / reverse switch 8 of the massage machine 1 shown in FIG.
It is assumed that the power switch 7 of the massage machine 1 is turned on.
Then, the reverse rotation of the motor 11 causes the worm gear 13 to rotate.
Rotates, and the respective worm wheels 14, 14 rotate relative to each other. Thereby, each drive shaft 16, 16 rotates relatively.

At this time, the driving force of each drive shaft 16, 16 is transmitted to each plunger 27, 27, and each base 2
The state is not transmitted to 1a and 21b. That is, the right drive shaft 16 rotates in the forward direction, and the one-way clutch 19b and the drive shaft 16 are disengaged. Then, the bush 20 and the base 21b are fixed with respect to the rotation of the drive shaft 16. That is, the one-way clutch 19b
(Bush 20), base 21 b, cylindrical member 22, and treatment element 10 are in a state of being stationary with respect to rotation of drive shaft 16.

On the other hand, the fixed gear 25 is
, And rotates in synchronization with the rotation of the drive shaft 16. Since the plunger 27 meshes with the fixed gear 25, the plunger 27 receives the rotational force from the fixed gear 25 and
6 rotates around the center of rotation. Thereby, the cam groove 3
2 pushes the pin 30 of the fixed shaft 26, so that the pin 30 relatively moves along the cam groove 32.

In the initial state, the pin 30 is located at the highest position of the cam groove 32 (the position of the other end of the fixed shaft 26) (see FIG. 7). Therefore, when the pin 30 is pushed by the cam groove 32, the plunger 27 advances to the other end of the fixed shaft 26 while rotating. Along with this, the acupressure element 28
Advance while rotating outward from the end face of the treatment element 10.

Thereafter, when the rotation angle of the drive shaft 16 becomes 45 °, the rotation angle of the plunger 27 becomes 90 °, and the tip of the acupressure element 28 protrudes halfway from the end face of the treatment element 10.
(See FIG. 11). Thereafter, the rotation angle of the drive shaft 16 is 90 °.
Then, the rotation angle of the plunger 27 becomes 180 °, and the acupressure element 28 is in the state of being most protruded from the end face of the treatment element 10 (see FIG. 12).

Thereafter, the rotation angle of the drive shaft 16 is 135 °.
Then, the rotation angle of the plunger 27 becomes 270 °, the acupressure element 28 retreats, and the state becomes almost the same as when the rotation angle of the plunger 27 is 45 ° (see FIG. 11). Thereafter, when the rotation angle of the drive shaft 16 becomes 180 °, the rotation angle of the plunger 27 becomes 0 °, the acupressure element 28 retracts most toward one end of the fixed shaft 26, and the end face of the acupressure element 28 is It is almost flush. That is, the state is almost the same as the initial state (see FIG. 8).

After that, the rotation angle of the drive shaft 16 becomes 180 °.
During the period from when the rotation angle of the plunger 27 returns to 0 °, the same operation as the above-described operation when the rotation angle of the plunger 27 ranges from 0 ° to 180 ° is performed, and then the operation returns to the initial state.

As described above, the plunger 27 is connected to the drive shaft 1.
6 makes two rotations during one rotation, and 2 in the axial direction of the fixed shaft 26.
Go back and forth twice. As a result, the acupressure element 28 is
Each time is rotated once, it comes and goes twice from the end face of the treatment element 10.

An angle detecting means (for example, an angle detecting sensor such as an encoder) for detecting the rotation angle of each of the drive shafts 16 and 16 is provided, and the motor 11 rotates in the opposite direction (each of the acupressure elements 28 and 28). When the power switch 7 is turned off (OFF),
Each drive shaft 16, 16 is rotated until the rotation angle of each drive shaft 16, 16 becomes 0 ° (the angle detection means detects the rotation angle 0 ° of each drive shaft 16, 16). Is also good. In this way, when the power switches 7 are turned off while the acupressure elements 28, 28 are protruding and retracting, the acupressure elements 28, 28 are automatically set to the most retracted state. it can.

<Method of Using Massage Machine> Next, a method of using the above-described massage machine 1 will be described. For example, when the user uses the massage machine 1 while sleeping, the following is performed. That is, the massage machine 1 shown in FIG. 1 is arranged at an appropriate position on the floor, and lies on the massage machine 1.

At this time, each treatment element 1 of the massage machine 1
The midline of the user is arranged on the reference plane F of the massage mechanism 12 of the massage machine 1 so that 0, 10 is pressed against the massage site (neck, shoulder, waist, etc.) desired by the user. Supine.

As described above, in a state where each of the treatment elements 10 and 10 is pressed against the massage site, the user tilts the forward / reverse switch 8 of the massage machine 1 to the forward direction and turns the power switch 7 on. throw into. Then, each treatment child 10,10
Are relatively rotated around the drive shaft 16 and rubbed and massaged so as to sandwich the massage site. At this time, each treatment element 10,1
Since the area of the convex curved surface of 0 is larger than the area of the end face of the acupressure element 28, the massage site is rubbed and rubbed.

Thereafter, the user operates the forward / reverse switch 8
Is turned to the reverse side, the rotation of each treatment element 10, 10 stops, and instead, each acupressure element 28, 28
It comes out while rotating from the end face of 0, and pushes the massage part of the user.

Here, the thickness (diameter of the end face) of the acupressure element 10
Is formed with a thickness close to that of an adult finger. For this reason, when the acupressure element 28 rotates and presses the massage site, acupressure stimulation is given to the massage site.
In particular, if the user presses the acupressure element 28 against the position corresponding to the acupoint, a massage effect by appropriate acupressure can be obtained.

Further, the relative rotation of the treatment elements 10, 10 changes the distance between the acupressure elements 28, 28, so that the distance between the acupressure elements 28, 28 can be adjusted according to the massage site. . Therefore, if the massage site is the shoulder, the acupuncture 2
The distance between 8, 28 is shortened, and if the massage site is the neck or waist, the acupressure element 28,
28 can be lengthened.

As described above, according to the massage machine 1 of the first embodiment, the pair of acupressure members 28, 28 are provided, and the user can enjoy the acupressure stimulation by the acupressure members 28, 28 as necessary. Can be. For this reason, it is possible to provide the user with acupressure stimuli that have not been enjoyed by the user in the past. In addition, each of the acupressure elements 28, 28 comes and goes while rotating. For this reason, a more appropriate acupressure stimulus can be given to the user as compared with a case where the massage part is simply pressed.

Further, according to the massage machine 1, each acupressure element 28, 28 operates by receiving a driving force from the driving shaft 16 (the conventional driving shaft for rotating the kneading balls) rotated by the worm gear 13 and the worm wheel 14. . For this reason, there is no need to provide a new power source or drive shaft to add a configuration for applying acupressure stimulation to the massage machine.

Further, the acupressure element 28 is disposed at the center of each of the treatment elements 10, 10, and the structure for operating each of the acupressure elements 28, 28 (fixed gear 25, fixed shaft 26, and plunger 27) is as follows.
Since the massage machine is arranged on each of the bases 21a and 21b, the size of the massage machine in the direction orthogonal to the reference plane F is suppressed.

Further, a spur gear is formed on the peripheral surface of each of the bases 21a and 21b, and the base 21a and the base 21b are in mesh with each other.
Is always kept symmetrical with respect to.

[Embodiment 2] Embodiment 2 is an example in which the massage machine of the present invention is applied to a chair-type massage machine, that is, the massage mechanism 12 is attached to the back of the chair-type body.
The massage machine 50 to which is attached will be described.

<Structure of Massage Machine> FIG. 13 (a) is a front view of the chair-type massage machine 50 according to Embodiment 2 in which exterior parts, cushions and the like have been removed, and FIG. FIG. 14 is a right side view of the massage machine 50 when cut along the line AA in FIG.

As shown in FIGS. 13A and 13B, the massage machine 50 has four support legs 5 on the upper surface of a flat base 51.
2 are provided, and a rectangular seat frame 53 on which the user of the massage machine 50 sits is provided on the upper part of each support leg 52.
Is supported. The seat frame 53 is connected via a hinge to a backrest frame 54 on which the user rests. Also, the backrest frame 54
Can adjust the reclining angle to a user's desired angle by an angle adjusting mechanism (not shown).

The backrest frame 54 is formed in the shape of a rectangular frame having a short direction and a long direction, and one end and the other end in the longitudinal direction of the frame are respectively provided with a support plate 5.
5, 56 are provided along the lateral direction, and both ends thereof are supported by the backrest frame 54.

On the center line in the longitudinal direction of the backrest frame 54, a conveying shaft 57 having a spiral groove (thread) formed on the peripheral surface is provided with a ball bearing embedded in the center of each of the support plates 55 and 56. It is rotatably supported by 58 and 59. One end of the transfer shaft 57 (an end on one end side of the backrest frame 54) penetrates a hole (not shown) provided in the support plate 55.
A pulley 65 is fixed coaxially.

The transport shaft 57 has a support portion 60
Is provided. The support section 60 includes a transport shaft 57.
With the rotation of the transport shaft 57,
The transport shaft 57 is relatively movable in the axial direction. Further, the support section 60 has a support arm 61, and the support arm 61 supports the motor 11 and the massage mechanism 12 described in the first embodiment.

Since the motor 11 and the massage mechanism 12 are the same as those described in the first embodiment, the description will be omitted (see FIGS. 2 to 7). On the back side of the massage mechanism 12, two support rails 62 and 63, both ends of which are supported by respective support plates 55 and 56, are provided, and the massage mechanism 12 is moved in the longitudinal direction of the backrest frame 54.
(In the axial direction of the transport shaft 57).

Further, on the upper left side of the support plate 55, a motor 64 for conveying the massage mechanism 12 is disposed.
The drive shaft of the motor 64 extends through a hole (not shown) provided in the support plate 55 to one end of the backrest frame 54. The drive shaft of the motor 64 has a pulley 6
The pulley 65 and the pulley 66 are connected via a belt 67.

Thus, the driving force due to the rotation of the motor 64 is transmitted to the transport shaft 57 in the order of the pulley 66, the belt 67, and the pulley 65, and the transport shaft 57 rotates. Since the motor 64 is rotatable in the forward and reverse directions, the transport shaft 57 rotates in both directions according to the rotation direction of the motor 64.

Further, a sensor 68 for detecting the upper limit position of the massage mechanism 12 and a sensor 69 for detecting the lower limit position of the massage mechanism 12 are provided in the frame of the backrest frame 54. Each sensor 68,

For example, suppose that the user of the massage machine 50 has turned on the drive switch (not shown) of the motor 64 when the massage mechanism 12 shown in FIG. Then, the driving force of the motor 64 is transmitted to the transport shaft 57 through the pulley 66, the belt 67, and the pulley 66, and the transport shaft 57 rotates in the forward direction.

Then, the support portion 60 screwed with the transport shaft 57 rotates relatively to the transport shaft 57, whereby the support portion 60 faces the other end of the backrest frame 54. To translate. The support part 60
Since the motor 11 and the massage mechanism 12 are supported via the support arm 61, the motor 11 and the massage mechanism 12 move in parallel to the other end of the backrest frame 54 as the support section 60 moves in parallel. At this time, since the massage mechanism 12 is supported by the support rails 62 and 63, the massage mechanism 12 is prevented from rotating around the transport shaft 57 with the rotation thereof.

Thereafter, when the sensor 68 detects the massage mechanism 12 due to the movement of the massage mechanism 12, a switching signal of the rotation direction is transmitted from the sensor 68 to the motor 64, and the rotation direction of the motor 64 is switched from the forward direction to the reverse direction. Can be Then, the rotation direction of the transport shaft 57 is
By switching from the forward direction to the reverse direction,
The support part 60 starts moving to one end side of the backrest part frame 54. As a result, the motor 11 and the massage mechanism 12 move to one end of the backrest frame 54.

Thereafter, when the sensor 69 detects the massage mechanism 12 due to the movement of the massage mechanism 12, a switching signal of the rotation direction is transmitted from the sensor 69 to the motor 64, and the rotation direction of the motor 64 is switched from the reverse direction to the forward direction. Can be Thereby, the massage mechanism 12 moves to the other end side of the backrest frame 54 again.

As described above, when the user turns on the drive switch of the motor 64, the massage mechanism 12 reciprocates between the upper limit position and the lower limit position until the drive switch is released (stopped). This allows the user to arrange the massage mechanism 12 at a desired height in the backrest. The massage machine 50 is provided with a forward rotation switch and a reverse rotation switch of the motor 64, and when one of them is turned on, the massage mechanism 12 moves to one of the one end side and the other end side of the backrest frame 54. It may be.

Thereafter, the massage mechanism 12 is moved to a desired height.
Is arranged, the user makes the treatment elements 10, 10 come into contact with a predetermined massage position by sitting on the seat and holding the backrest. Thereafter, the user operates the massage mechanism 12 in the same manner as described in the first embodiment.
Is operated, the treatment elements 10, 10 of the massage mechanism 12 are operated.
Is rubbed and rubbed so as to sandwich the massage part of the user, so that the user is given a rubbing and rubbing stimulus. In addition, the user can enjoy the acupressure stimulation by moving the acupressure elements 28, 28 forward and backward.

Further, since the user can operate the massage mechanism 12 while moving the massage mechanism 12, for example, the user can move the acupressure elements 28, 28 in the axial direction of the transport shaft 57 while moving them in and out. Thus, the user can enjoy acupressure stimulation along the back muscles.

In the first embodiment and the second embodiment, the case where the abutment timings of the acupressure members 28 are synchronized has been described. Are shifted by 180 ° so that they can appear and disappear alternately.
