Description

Massage device

The present invention relates to a massage apparatus in which different massage modes can be selected.

Conventionally, massage for a user's treatment part is massaged by moving the treatment element while the treatment element is pressed against the treatment part, and massage is performed by hitting the treatment element against the treatment part. “Tapping massage” is known such as “grabbing massage” in which a treatment part is sandwiched between two treatment elements and massage is performed while stimulating the treatment part.

These different massages are operated independently or in cooperation depending on the user's preference because there is a difference in the treatment effect on the treatment part and there is a difference in the massage feeling received by the user. Therefore, in a massage apparatus like patent document 1, a drive part is provided for every massage function, and various massages are enabled by controlling a plurality of drive parts.

That is, Patent Document 1 discloses a massage machine in which a strength driving motor, a kneading driving motor, a tapping driving motor, and the like are provided.

Hereinafter, the massage device of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the massage apparatus 1 of this embodiment is a housing 2 (apparatus) having a handle that extends to the left and right so as to pass over the treatment part with respect to the treatment part such as a user's shoulder and waist. The treatment part is massaged by turning the main body) and pressing the treatment element built in the housing 2 against the treatment part.

Specifically, the massage device 1 of the present embodiment includes a housing 2 having an appearance that is U-shaped when viewed from above. As for this housing | casing 2, the part of the right-and-left both sides protruded toward the front is made into

handle part

3L, 3R. Further, between the left and

right handle portions

handle parts

3L and 3R mentioned above with a hand, and changing a position.

Specifically, the housing 2 between the left and

right handle portions

3L, 3R is formed with an opening 5 that opens forward. And the massage mechanism 4 mentioned above is accommodated in the inside of the housing | casing 2 so that the treatment element (The greasing treatment element 6 and the grip treatment element 7 mentioned later) may protrude ahead from this opening part 5. FIG.
In addition, the housing 2 located in the vicinity of the left handle portion 3L has massage conditions such as a power button for supplying power to the massage mechanism 4, a selection button for selecting a massage course and a massage mode, treatment time and treatment strength.

In the actual massage device 1, the opening 5 of the housing 2 is covered with a cover that prevents foreign matter from entering the massage mechanism 4, but in FIG. 1, the cover is omitted and illustrated. Yes.
FIG.2 and FIG.3 shows the massage mechanism 4 provided in the massage apparatus 1 of this embodiment.

The massage mechanism 4 of the present invention performs a massage different from the first massage mechanism 11 and the drive unit 10 that generates a rotational driving force, the first massage mechanism 11 that massages the user's treatment unit. It has the 2nd massage mechanism 12, and the power transmission mechanism 13 which can transmit the rotational driving force of the drive part 10 with respect to the 1st massage mechanism 11 and the 2nd massage mechanism 12. FIG.

The power transmission mechanism 13 described above transmits the rotational drive force generated in both the first massage mechanism 11 and the second massage mechanism 12 when the drive unit 10 generates a rotational drive force in the positive direction. When the driving unit 10 generates a rotational driving force in the reverse direction, the rotational driving force generated only by the first massage mechanism 11 is transmitted.
Hereinafter, the drive part 10, the 1st massage mechanism 11, the 2nd massage mechanism 12, and the power transmission mechanism 13 which comprise the massage mechanism 4 of this embodiment are demonstrated.

The drive unit 10 is a part that generates a rotational driving force for driving the first massage mechanism 11 and the second massage mechanism 12 described above, and includes a single drive motor 14 in the present embodiment. . This drive motor 14 is a dual-axis motor that is arranged so that the drive shaft 15 is directed in the vertical direction. The drive shaft 15 protrudes upward (one-end side drive shaft 15U) and the drive shaft 15 protrudes downward (others). The rotation driving force can be output from each of the end driving shaft 15D).

In the case of the present embodiment, a rotational driving force is output from the upper drive shaft 15U (one end side drive shaft) to the first massage mechanism 11, and a second drive shaft 15D (the other end side drive shaft) is the second. The rotational driving force is output to the massage mechanism 12. That is, the first power transmission mechanism 16 is provided between the upper drive shaft 15U and the first massage mechanism 11, and the second drive shaft 15D is disposed between the second massage mechanism 12 and the second massage mechanism 12. The power transmission mechanism 17 is provided so that the rotational driving force of the drive shaft 15 can be transmitted to the

massage mechanisms

11 and 12 separately.

By the way, the massage apparatus 1 of the present invention is characterized by performing various massages by selectively using a plurality of

massage mechanisms

11 and 12 while being a single drive motor 14. In this way, the structure of the massage mechanism 4 is simple because the number of drive units 10 can be reduced if the rotational drive force can be transmitted separately from the single drive motor 14 to the plurality of

massage mechanisms

11 and 12. Therefore, an increase in the weight of the apparatus and an increase in the price can be suppressed.

Therefore, in the massage mechanism 4 provided in the massage device 1 of the present embodiment, the drive shaft 15 of the drive unit 10 is in the positive direction in either the first power transmission mechanism 16 or the second power transmission mechanism 17 described above. A rotating drive force is transmitted when the drive shaft 15 is rotated, but the drive shaft 15 is not transmitted when the drive shaft 15 is rotated in the reverse direction. For example, in the case of the massage mechanism 4 of the present embodiment, the second power transmission mechanism 17 described above is used that switches transmission of rotational driving force depending on the rotational direction of the drive shaft 15. Specifically, in the present embodiment, a one-way clutch 18 (one-way clutch portion) is provided as means for switching transmission of rotational driving force depending on the rotational direction of the drive shaft 15.

As the one-way clutch 18 of the present invention, various means can be used as long as the transmission of the rotational driving force can be switched depending on the rotational direction of the drive shaft 15. The one-way clutch 18 shown in the figure is formed on a toothed portion provided on a driving shaft (second rotating shaft 19 described later) and an inner peripheral side of a driven member (second worm wheel 21 described later). A claw portion. The one-way clutch 18 is formed with the teeth of the teeth inclined with respect to the tangential direction of the second worm wheel 21, and the claw engages with or does not engage with the teeth depending on the rotation direction of the second worm wheel 21. The ratchet mechanism is configured.

That is, as shown in FIG. 5A, in the massage mechanism 4 of this embodiment, when the drive shaft 15 rotates in the forward direction, the claw portion of the one-way clutch 18 meshes with the tooth portion and rotates in the forward direction. The rotational driving force of the driving shaft 15 is transmitted to the second rotating shaft 19. However, as shown in FIG. 5B, when the drive shaft 15 rotates in the reverse direction, the claw portion of the one-way clutch 18 slides with respect to the tooth portion, and the rotational drive force of the drive shaft 15 rotating in the reverse direction is It is not transmitted to the second rotating shaft 19.

As a result, as shown in FIG. 6A, when the drive shaft 15 rotates in the forward direction, both the first rotary shaft 23 and the second rotary shaft 19 are rotationally driven and coupled to the first rotary shaft 23. The second massage mechanism 12 connected to the first massage mechanism 11 and the second rotation shaft 19 operates.
However, as shown in FIG. 6B, when the drive shaft 15 rotates in the reverse direction, even if the first rotating shaft 23 is driven to rotate, the second rotating shaft 19 is not driven to rotate. As a result, even if the first massage mechanism 11 operates, the second massage mechanism 12 does not operate.

The ratchet mechanism described above is merely an example of a one-way clutch 18 that switches transmission of rotational driving force depending on the rotational direction of the drive shaft 15. A member using a sprag, a cam, or the like may be used as a member that switches transmission of the rotational driving force depending on the rotational direction of the drive shaft 15.
In the massage mechanism 4 described above, transmission of the rotational driving force is switched depending on the rotation direction of the drive shaft 15, so that the massage mechanism 4 to be operated can be selected simply by switching the rotation direction of the drive motor 14. Therefore, even when the number of the drive motors 14 is one, it is possible to perform massages rich in variations by switching the massage mechanism 4 to be operated.

The first power transmission mechanism 16 and the second power transmission mechanism 17 described above include “massage type” and “position of the treatment unit” in the massage mechanism 4 using the rotational driving force of the drive unit 10. Those different from each other can be used. For example, when the massaging mechanism 24 is the first massage mechanism 11 as in the present embodiment, the tapping massage mechanism 25 having a different “type of massage” can be the second massage mechanism 12. When the massaging mechanism for massaging the shoulder is the first massaging mechanism 11, the massaging massaging mechanism for massaging the back, which is the massaging massaging mechanism 24 having the same “type of massage”, is used as the second massaging mechanism 12. You can also. Further, the first massage mechanism 11 or the second massage mechanism 12 may be provided with a plurality of massaging massage mechanisms 24, hitting massage mechanisms 25, gripping massage mechanisms 26, and the like. In other words, the massage mechanism 4 according to the present invention is configured such that the rotational driving force generated by the drive unit 10 is transmitted through the power transmission mechanism 13 so that “massage type” and “position of the treatment unit” are different from each other. 4 and the massage mechanism 4 can be selectively operated.

Hereinafter, as an example of the massage mechanism 4, the massaging mechanism 24 and the grasping massage mechanism 26 are squeezed by the first massage mechanism 11, and the massage mechanism 25 is struck by the second massage mechanism 12 whose operation state is switched in the rotation direction of the driving unit 10. The massage apparatus 1 of the present embodiment will be described with an example using the
As shown in FIG. 3, the first power transmission mechanism 16 described above has a first worm gear 27 attached to one end side drive shaft 15U of the drive motor 14 and a direction crossing the upper drive shaft 15U (left and right). A first worm wheel 29 that is attached to the deployed reduction shaft 28 (in the direction) and meshes with the first worm gear 27. Further, the reduction shaft 28 is further provided with a first reduction gear 30, and the first reduction gear 30 meshes with the second reduction gear 31 of the first rotating shaft 23 arranged in parallel with the reduction shaft 28. That is, the reduction shaft 28, the first reduction gear 30, the first rotation shaft 23, and the second reduction gear 31 described above transmit the rotational driving force of the drive shaft 15U on the upper side of the drive motor 14 to the first rotation shaft 23. The first power transmission mechanism 16 is configured, and the rotational driving force of the upper drive shaft 15U is transmitted to the first rotation shaft 23 in a decelerated state.

In the case of the massage device 1 according to the present embodiment, the first massage mechanism 11 exclusively performs massage massage. Therefore, hereinafter, the first rotation shaft 23 may be referred to as a stagnation rotation shaft.
The itch massage mechanism 24 presses the massage treatment element 6 against the treatment parts such as the shoulder, back, and waist of the user, and performs massage massage with the massage treatment element 6 against the treatment part.

The inclination direction of the inclined cam surface 32 is opposite between the inclined boss member 33 at the left end and the inclined boss member 33 at the right end. That is, in FIG. 4, when the left end inclined cam surface 32 is inclined downward to the left, the right end inclined cam surface 32 is inclined downward to the right. When the left end inclined cam surface 32 is inclined downward to the right, the right end inclined cam surface 32 is inclined downward to the left.

A cylindrical eccentric cam surface 37 is formed on the outer peripheral surface of each eccentric boss member 38 and circulates around an axis that is eccentric with respect to the axis of the stagnation rotation shaft. The axis of the eccentric cam surface 37 is eccentric in the same direction by the left-end eccentric boss member 38 and the right-end eccentric boss member 38, and the center (cylindrical) of the left-end eccentric cam surface 37 in a certain rotational phase. When the rotation axis of the surface is offset in a certain direction, the center of the eccentric cam surface 37 at the right end (rotation axis of the cylindrical surface) is also offset in the same direction. A second annular fitting portion 39 is rotatably fitted to these eccentric cam surfaces 37.

In the hitting massage mechanism 25 described above, the rotational driving force output from the lower drive shaft 15D of the drive motor 14 is transmitted to the hitting rotary shaft (second rotary shaft 19) through the second power transmission mechanism 17 described above. . This rotational driving force is transmitted as a reciprocating movement (vibration) along the up and down direction of the kneading arm member 35 through the hitting boss member 43, the connecting shaft 45, and the universal joint (ball joint portion 36 and boot portion 44). . Therefore, in the second massage mechanism 12 described above, the massaging arm member 35 reciprocates in the front-rear direction at short time intervals by the rotational driving force output from the drive shaft 15D on the lower side of the drive motor 14, and treatment is performed. It is possible to perform a hitting massage such as hitting the massage treatment element 6 against the part.

The above-described operation of the second massage mechanism 12 is performed when the rotation direction of the drive shaft 15 is the positive direction. When the rotation direction of the drive shaft 15 is reversed, the rotation driving force of the drive shaft 15 is not transmitted to the second rotation shaft 19 (striking rotation shaft) by the one-way clutch 18 described above, so the second The massage mechanism 12 does not perform a massage operation.
That is, in the one-way clutch 18 of this embodiment that employs a ratchet mechanism, when the drive shaft 15 rotates in the forward direction, the claw portion 22 of the one-way clutch 18 meshes with the tooth portion 20 and rotates in the forward direction. The rotational driving force of the driving shaft 15 is transmitted to the second rotating shaft 19. However, when the drive shaft 15 rotates in the reverse direction, the claw portion 22 of the one-way clutch 18 slides with respect to the tooth portion 20, and the rotational drive force of the drive shaft 15 rotating in the reverse direction is the second rotation shaft 19. Not transmitted to.

As a result, when the drive shaft 15 rotates in the forward direction, the first rotary shaft 23 and the second rotary shaft 19 are both driven to rotate, and the first massage mechanism 11 and the second massage mechanism 12 operate. To do. However, when the drive shaft 15 rotates in the reverse direction, even if the first rotating shaft 23 is driven to rotate, the second rotating shaft 19 is not driven to rotate. As a result, even if the first massage mechanism 11 operates, the second massage mechanism 12 does not operate.

In the massage apparatus 1 of this embodiment mentioned above, the 1st massage mechanism 11 and the 2nd massage mechanism 12 cooperate with the massage state in which the 1st massage mechanism 11 and the 2nd massage mechanism 12 cooperate by the rotation direction of the drive shaft 15. However, the second massage mechanism 12 can be switched to a massage state where it does not operate. For this reason, various massages can be performed even if only one drive unit 10 (drive motor 14) is used.

In addition, in order to enable various massages, only one expensive and heavy drive motor 14 is required, so that the structure of the device is simple and the weight of the device is light, but the price is rising. It can also be suppressed.
Each embodiment disclosed this time should be considered as illustrative in all points and not restrictive. In particular, in each embodiment disclosed this time, matters that are not explicitly disclosed, for example, operating conditions and operating conditions, various parameters, dimensions, weights, volumes, etc. of the constituents are within the range normally practiced by those skilled in the art. It does not deviate and employs a value that can be easily assumed by those skilled in the art.

For example, in the present specification, the description has been made by taking a hand-held massage machine as an example. However, the massage apparatus 1 of the present invention includes a chair-type massage machine, a seat-type massage machine, a seat-chair type massage machine, and the like. It is possible to use.
Moreover, in embodiment mentioned above, the massage apparatus 1 of this invention was demonstrated by giving the example which provided the one-way clutch 18 in the tapping massage mechanism 25 (2nd massage mechanism 12). However, the place where the one-way clutch 18 is provided is not limited to the hitting massage mechanism 25 (second massage mechanism 12). For example, the one-way clutch 18 may be provided on the massaging mechanism 24 or the gripping massaging mechanism 26, specifically on the first rotating shaft 23 of the first massaging mechanism 11.
