Description

Technical Field

[0001] The present invention relates to a massager, for example, capable of clamping and kneading a user's hand or other treatment area for massage. Background Technology

[0002] Previously, massagers were sold on the market that were specifically designed for the user's treatment area, i.e., massagers limited to a specific target audience. For example, lower limb massagers that massage the calves or feet are examples of such massagers.

[0003] In addition, hand massagers that massage the user's hands have also been developed. An example of a hand massager is shown in Patent Document 1.

[0004] Prior art literature

[0005] Patent documents

[0006] Patent Document 1: Japanese Patent Publication No. 2020-031792. Summary of the Invention

[0007] The problem that the invention aims to solve

[0008] However, if an inflatable and contractible airbag, as in Patent Document 1, is used to massage the user's hand, sometimes the airbag applies excessive pressure to the user's hand, causing pain and discomfort. In other words, a comfortable massage cannot be received.

[0009] Furthermore, the size and thickness of the hand (fingers, palm, etc.) vary depending on individual differences. In devices for inserting fingers, such as those in Patent Document 1, for example, if the hand is large, the fingers may not be able to enter or may stop midway and not be able to enter completely, thus creating a problem before use.

[0010] However, in hand massage performed by a masseur (human technique), not only is pressing massage performed, but also massage such as grasping the hand and stretching it along its length (kneading and stretching movements) becomes very effective. However, in the device of Patent Document 1, stretching movements of the hand are not possible.

[0011] Therefore, in view of the above-mentioned problems, the present invention aims to provide a massager that can clamp the user's hand and perform kneading, kneading and stretching movements, and can be used regardless of the size of the hand to effectively massage the user.

[0012] Solution for solving the problem

[0013] In order to achieve the above objectives, the following technical solutions are adopted in this invention.

[0041] The following is for reference Figures 1 to 12 The following describes an embodiment of the massager 1 according to the present invention. Furthermore, the embodiments described below are examples embodying the present invention and are not intended to limit the scope of the invention to these specific examples. Additionally, regarding the accompanying drawings, some parts are sometimes omitted for ease of observation.

[0042] Additionally, the directions illustrated in the accompanying drawings are as follows: for example, the front side (the side with the switch 9) as observed by the user inserting their hand H into the insertion recess 2 and using the massager 1 is taken as the forward direction, and the inside side (the side with the power cord 10) is taken as the rear direction. Furthermore, the left-right and up-down directions are consistent with the directions observed by the user.

[0043] In this embodiment, the palm P of the hand H is designated as the first treatment area, and the fingers F connected to the palm P are designated as the second treatment area. Additionally, the portion from the elbow to the hand (wrist) is designated as the forearm A. This forearm A is designated as the third treatment area (see reference). Figure 1 ).

[0044] [First Implementation]

[0045] The first embodiment of the massager 1 according to the present invention will be described.

[0046] exist Figures 1 to 7 The diagram shows an overview and apparatus configuration of a first embodiment of the massager 1 according to the present invention.

[0047] like Figures 1 to 7 As shown, the massager 1 (hand massager) of the present invention is placed on a flat and stable surface such as a table. The hand H is placed into the insertion recess 3, and the palm P (first treatment part) and the fingers F (second treatment part) are kneaded and massaged, and the entire hand H is stretched.

[0048] The massager 1 of this embodiment includes: a housing 2 having an insertion recess 3; a first massage part 4 for clamping and massaging a palm P inserted into the insertion recess 3; a second massage part 5 for clamping and massaging a finger F inserted into the insertion recess 3; and a drive part 6 for driving the first massage part 4 and the second massage part 5.

[0049] The outer shell 2 has an internal space that is slightly larger than the hand H (i.e., large enough to cover the size of the hand). That is, the outer shell 2 is a frame with a relatively long space in the front-to-back direction.

[0050] Inside the outer casing 2, there is a first massage unit 4 for massaging the palm P, a second massage unit 5 for massaging the fingers F, a drive unit 6 for driving the first massage unit 4 and the second massage unit 5, and a control unit 7 for controlling the drive unit 6.

[0051] In addition, inside the outer casing 2, there is a support (not shown) on which the drive unit 6 and the like are installed. On the bottom surface (lower surface) of the outer casing 2, there are legs 8 that can be stably placed on a table or the like.

[0052] The outer casing 2 has openings at the top, front, and rear, forming insertion recesses 3 that are longer in the front-to-back direction. The insertion recesses 3 are U-shaped when viewed from the front. The insertion recesses 3 are sized to allow insertion of the hand H, which consists of the palm P (first treatment area) and the fingers F (second treatment area).

[0053] The user inserts their hand H vertically (with the thumb on top and the palm P facing left and right) into the U-shaped insertion recess 3 from above.

[0054] The insertion recess 3 is provided with an inner lining material (not shown) that covers the opening. This inner lining material can be a cushioning material that provides good skin-feeling comfort to the user's hand H. That is, the cushioning material makes the insertion of the first and second massage components slightly gentler and more comfortable. In other words, it allows the hand H to receive a massage similar to that of a therapist (massage therapist, etc.). Furthermore, the inner lining material prevents the user's hand H from entering the device, thus preventing accidental entanglement.

[0055] On the lower front side of the outer casing 2, there is a switch 9 that can operate the drive unit 6 to turn on / off or adjust the intensity of massage, etc. On the other hand, on the lower rear side of the outer casing 2, there is a power cord 10 that supplies power to the drive unit 6.

[0056] Furthermore, the shape of the outer casing 2 or the insertion recess 3 is not limited to the illustrated shape, as long as it is a structure that can stably support the device on a table or the like even during operation, and a structure that makes it easy to insert the hand H. In addition, although not shown, a hot air heater that can heat the hand H and promote blood flow to improve the massage effect can also be provided inside the outer casing 2.

[0057] Therefore, the first massage unit 4 is provided on the front side, and the second massage unit 5 is provided on the rear side. That is, the first massage unit 4 and the second massage unit 5 are arranged side by side in the front-to-back direction.

[0058] The first massage unit 4 causes the first massage component 11 to swing back and forth and side to side in an undulating manner, so that the first treatment component 12 provided on the first massage component 11 clamps the palm P and performs a pressing massage, and performs a stretching action by pulling forward. The first massage unit 4 is provided on the inner front side of the outer casing 2 and is supported by a support.

[0059] like Figures 1 to 7 As shown, the first massage section 4 is a region in which the palm P (first treatment section) inserted into the insertion recess 3 is clamped and massaged. The first massage section 4 has a pair of left and right first massage members 11 facing each other and clamping and massaging the palm P from the left and right directions.

[0060] The first massage component 11 is an elongated component that extends upwards. In this embodiment, the first massage component 11 is a fan-shaped part that expands outwards in a flat, plate-like manner at the top.

[0061] At the base (lower end) of the first massage member 11, a first annular fitting portion 16 with a through opening in the front-rear direction is formed. The first annular fitting portion 16a formed on the left side of the first massage member 11a is provided on the front side.

[0062] On the other hand, the first annular fitting portion 16b formed on the right side of the first massage member 11b is provided on the rear side. That is, the first annular fitting portion 16a and the first annular fitting portion 16b are provided in a stacked manner in the front-back direction.

[0063] At the end (upper end) of the first massage component 11, there is a first treatment component 12 for pressing and massaging the palm part P (first treatment part).

[0064] The first treatment member 12a of the first massage member 11a formed on the left side is positioned facing to the right. On the other hand, the first treatment member 12b of the first massage member 11b formed on the right side is positioned facing to the left. That is, the first treatment member 12a and the first treatment member 12b are arranged facing each other, and the palm P is clamped in from the outside to the inside in the left and right directions and pressed in for massage.

[0065] Additionally, a first connecting portion 13 is provided at the base end of the first massage member 11. A cylindrical protrusion 13a is provided at the base end of the first massage member 11a on the left side. A cylindrical hole 13b is provided at the base end of the first massage member 11b on the right side.

[0066] The first connecting part 13 is connected by the protrusion 13a being rotatably inserted into the hole 13b, thus restricting the rotation of the right first massage member 11b together with the rotating shaft 21. In addition, the left first massage member 11a is restricted from rotating together with the rotating shaft 21 by the first rotation limiting part 17.

[0067] At the lower part of the first massage unit 4, a first swing conversion unit 14 is provided. The first swing conversion unit 14 converts the rotational driving force from the rotation shaft 21 into a reciprocating swing motion, causing the pair of left and right first massage members 11 to swing back and forth and left and right in an undulating manner. That is, the first swing conversion unit 14 causes the pair of left and right first massage members 11 to approach separation in the left-right direction and swing in the front-back direction.

[0068] The first swing conversion part 14 includes: a first rotating boss member 15, which is fixed to the rotating shaft 21 and rotates eccentrically relative to the rotating shaft 21; a first annular fitting part 16, which is provided at the base end of the first massage member 11 and is embedded in the outer periphery of the first rotating boss member 15; and a first rotation limiting part 17, which limits the first massage member 11 from rotating together with the rotating shaft 21.

[0069] The first rotating boss component 15 is a cylindrical component that is externally fitted onto the rotating shaft 21. The first rotating boss component 15 rotates as the rotating shaft 21 rotates. On the outer peripheral surface of the first rotating boss component 15, there is a first cam surface 18 that is inclined relative to the axis of the rotating shaft 21.

[0070] In this embodiment, in the legend (e.g., Figure 4 In the first rotating boss component 15, the first rotating boss component 15 is positioned in the left-front direction relative to the axis of rotation 21. Additionally, the first cam surface 18 is positioned in the left-rear direction relative to the axis of rotation 21. However, the first rotating boss component 15 rotates, thus changing its orientation accordingly.

[0071] The axis of the first rotating boss component 15 is eccentric relative to the axis of the rotating shaft 21, and the first cam surface 18 is inclined. Therefore, the first rotating boss component 15 rotates tilted and eccentrically relative to the rotation of the rotating shaft 21. A first annular fitting portion 16 is externally fitted on the outside of the inclined first cam surface 18.

[0072] In this embodiment, the first rotating boss member 15a is positioned further forward than the first massage member 11a on the left side. The first rotating boss member 15b is positioned further rearward than the first massage member 11b on the right side.

[0073] The first annular fitting portion 16 is formed at the base end of the first massage member 11. The first annular fitting portion 16 has a through opening in the front-rear direction, and the inner diameter of the opening is approximately the same as the outer diameter of the first rotating boss member 15 (first cam surface 18).

[0074] However, although the first annular fitting portion 16 faces the front-to-back direction, it is positioned in an inclined direction (the same direction as the first cam surface 18) relative to the axis of rotation 21. In this embodiment, as illustrated in the figures (e.g., Figure 4 In the first annular fitting portion 16, the first rotating boss member 15 is similarly positioned facing left-front relative to the axis of rotation 21. However, the first annular fitting portion 16 rotates, thus changing its orientation accordingly.

[0075] The first annular fitting portion 16 externally fits the first rotating boss member 15 in a state of relative rotational freedom via a bearing. In addition, a rotating shaft 21 with its axis facing the front-rear direction is provided through the first annular fitting portion 16.

[0076] In this embodiment, the first annular fitting portion 16a at the base end of the first massage member 11a on the left side fits the first rotating boss member 15a externally, and the first annular fitting portion 16b at the base end of the first massage member 11b on the right side fits the first rotating boss member 15b externally.

[0077] The first rotating boss component 15 with the inclined first cam surface 18 and the first annular fitting portion 16 embedded therein transform the rotational driving force of the rotating shaft 21 into tilting rotation and eccentric rotation, thereby realizing the reciprocating swing motion of the first massage component 11 (which is a reciprocating swing motion in the front, back and left and right when viewed from above).

[0078] The first rotation limiting part 17 restricts the first annular fitting part 16 from rotating together with the first rotating boss member 15. The first rotation limiting part 17 is provided at a lower position than the rotation axis 21. The first rotation limiting part 17 has a downward-facing limiting pin 19 and a limiting groove 20 into which the limiting pin 19 is slidably inserted.

[0079] The limiting pin 19 is a cylindrical protrusion that protrudes downwards from the base end of the first massage member 11a on the left side (below the first annular fitting portion 16). The limiting groove 20 is a groove that extends in the front-rear direction and is installed at the bottom of the housing 2. This limiting groove 20 is located below the limiting pin 19. The limiting pin 19 is inserted into the limiting groove 20 in a manner that allows it to slide freely in the front-rear direction.

[0080] The rotating shaft 21 rotates by the rotational driving force output from the drive unit 6. The rotating shaft 21 is mounted inside the housing 2 with its axis pointing in the front-to-back direction.

[0081] In detail, the front end of the rotating shaft 21 is provided to pass through the base end (first annular fitting portion 16) of the first massage member 11. The central portion of the rotating shaft 21 in the longitudinal direction passes through the gearbox 24 of the drive unit 6 and is rotatably supported by the bearing 22. In addition, the rear end of the rotating shaft 21 is provided to pass through the base end (second annular fitting portion 30) of the second massage member 25. Furthermore, a control unit 7 for controlling the drive unit 6 and the like is provided on the right side of the rotating shaft 21.

[0082] The drive unit 6 drives the first massage unit 4 and the second massage unit 5 synchronously. The drive unit 6 is disposed inside the housing 2. The drive unit 6 has a drive motor 23 that outputs rotational driving force and a gearbox 24 that reduces the rotational driving force to a predetermined speed. Furthermore, in this embodiment, the housing storing the drive motor 23 is integrally formed with the gearbox 24.

[0083] The device includes a drive motor 23 that drives the first massage unit 4 and the second massage unit 5. The drive motor 23 is located on the underside of the rotating shaft 21, with its output shaft facing forward. The output shaft of the drive motor 23 is inserted into a gearbox 24 located at the front.

[0084] The gearbox 24 houses multiple gears 24a, etc., to reduce the speed to a predetermined speed. The gearbox 24 uses multiple gears to reduce the rotational driving force input from the output shaft of the drive motor 23 and output it to the rotating shaft 21. That is, the drive motor 23 is connected to the rotating shaft 21 via the gearbox 24.

[0085] The second massage unit 5 is located behind the first massage unit 4. The second massage unit 5 causes the second massage member 25 to swing back and forth and side to side in an undulating manner, so that the second treatment member 26 provided on the second massage member 25 can clamp the finger F and perform a pressing massage, and perform a stretching action by pulling forward. The second massage unit 5 is provided on the inner rear side of the outer casing 2 and is supported by a support.

[0086] like Figures 1 to 7 As shown, the second massage section 5 is a region where a finger F (second treatment section) inserted into the insertion recess 3 is clamped and massaged. The second massage section 5 has a pair of left and right second massage members 25 facing each other and clamping and massaging the finger F from the left and right directions.

[0087] In this embodiment, the second massage member 25 is a member that extends upward and bends forward. A long rod on which the second treatment member 26 is mounted is formed at the bend.

[0088] At the base (lower end) of the second massage member 25, a second annular fitting portion 30 with a through opening in the front-rear direction is formed. The second annular fitting portion 30a formed on the left side of the second massage member 25a is provided on the rear side.

[0089] On the other hand, the second annular fitting portion 30b formed on the right side of the second massage member 25a is provided on the front side. That is, the second annular fitting portion 30a and the second annular fitting portion 30b are provided in a stacked manner in the front-back direction.

[0090] At the end (upper end) of the second massage member 25, a second treatment member 26 is provided for pressing and massaging the finger part F (the second treatment part). Furthermore, in this embodiment, the second treatment member 26 is a freely rotating roller.

[0091] The second treatment piece 26 is equipped with multiple overlapping long rods extending upward from the curved portion of the second massage member 25, allowing for free rotation. That is, the second treatment piece 26 is in the shape of a string-together ball. The second treatment piece 26a on the left and the second treatment piece 26b on the right are arranged facing each other, and the finger F is inserted from the outside to the inside in the left-right direction for pressing and massaging.

[0092] Additionally, a second connecting portion 27 is provided at the base end of the second massage member 25. A cylindrical protrusion 27a is provided at the base end of the second massage member 25a on the left side. A cylindrical hole 27b is provided at the base end of the second massage member 25b on the right side.

[0093] The second connecting part 27 is connected by allowing the protrusion 27a to rotatably insert into the hole 27b, thus restricting the rotation of the second massage member 25b on the right side together with the rotating shaft 21. Furthermore, the second massage member 25a on the left side is restricted from rotating together with the rotating shaft 21 by the second rotation limiting part 31.

[0094] At the lower part of the second massage unit 5, a second swing conversion unit 28 is provided. The second swing conversion unit 28 converts the rotational driving force from the rotation shaft 21 into a reciprocating swing motion, causing the pair of left and right second massage members 25 to swing back and forth and left and right in an undulating manner. That is, the second swing conversion unit 28 causes the pair of left and right second massage members 25 to approach separation in the left-right direction and swing in the front-back direction.

[0095] The second swing conversion part 28 includes: a second rotating boss member 29, which is fixed to the rotating shaft 21 and rotates eccentrically relative to the rotating shaft 21; a second annular fitting part 30, which is provided at the base end of the second massage member 25 and is embedded in the outer periphery of the second rotating boss member 29; and a second rotation limiting part 31, which limits the second massage member 25 from rotating together with the rotating shaft 21.

[0096] The second rotating boss component 29 is a cylindrical component that is externally fitted onto the rotating shaft 21. The second rotating boss component 29 rotates as the rotating shaft 21 rotates. On the outer peripheral surface of the second rotating boss component 29, there is a second cam surface 32 that is inclined relative to the axis of the rotating shaft 21.

[0097] In this embodiment, in the legend (e.g., Figure 4 In the first rotating boss 15, the second rotating boss member 29 is positioned in the forward right direction relative to the axis of rotation 21. Additionally, the second cam surface 32 is positioned in the rear right direction relative to the axis of rotation 21. However, the second rotating boss member 29 rotates, thus changing its orientation appropriately, but in a different orientation than the first rotating boss member 15.

[0098] Furthermore, the second cam surface 32 is inclined in a direction different from the axial direction of the rotation axis 21 and also in a direction different from the first cam surface 18. That is, the second cam surface 32 and the first cam surface 18 are inclined in a V-shape (not parallel) when viewed from above.

[0099] The axis of the second rotating boss component 29 is eccentric relative to the axis of the rotating shaft 21, and the second cam surface 32 is inclined. Therefore, the second rotating boss component 29 rotates tilted and eccentrically relative to the rotation of the rotating shaft 21. A second annular fitting portion 30 is externally fitted on the outer side of the inclined second cam surface 32.

[0100] In this embodiment, the second rotating boss member 29a is positioned further forward than the second massage member 25a on the left. The second rotating boss member 29b is positioned further rearward than the second massage member 25b on the right.

[0101] The second rotating boss components 29a and 29b are, for example, depicted... Figure 5 The two black lines shown rotate in a manner that the circles are separated or overlapped. In addition, the first rotating boss parts 15a and 15b also rotate in a manner that draws the same tracks as the second rotating boss parts 29a and 29b.

[0102] The second annular fitting portion 30 is formed at the base end of the second massage member 25. The second annular fitting portion 30 has a through opening in the front-rear direction, and the inner diameter of the opening is approximately the same as the outer diameter of the second rotating boss member 29 (second cam surface 32).

[0103] However, although the second annular fitting portion 30 faces the front-to-back direction, it is positioned in an inclined direction (the same direction as the second cam surface 32) relative to the axis of rotation 21. In this embodiment, as illustrated in the figures (e.g., Figure 4 In the second annular fitting portion 30, the second cam surface 32 is similarly positioned in the right-forward direction relative to the axis of rotation 21. However, the second annular fitting portion 30 rotates, thus changing its orientation appropriately, but rotating in an orientation different from that of the first annular fitting portion 16.

[0104] Furthermore, the second annular fitting portion 30 is obliquely arranged in a direction different from the axial direction of the rotation axis 21 and also in a direction different from the first annular fitting portion 16. That is, the second annular fitting portion 30 and the first annular fitting portion 16 are obliquely arranged in a figure-eight shape (not parallel) when viewed from above.

[0105] The second annular fitting portion 30 externally fits the second rotating boss member 29 in a state of relative rotational freedom via a bearing. In addition, a rotating shaft 21 with its axis facing the front-rear direction is provided through the second annular fitting portion 30.

[0106] In this embodiment, the second annular fitting portion 30a at the base end of the second massage member 25a on the left side fits the second rotating boss member 29a externally, and the second annular fitting portion 30b at the base end of the second massage member 25b on the right side fits the second rotating boss member 29b externally.

[0107] The second rotating boss component 29 with the inclined second cam surface 32 and the second annular fitting portion 30 embedded therein transform the rotational driving force of the rotating shaft 21 into tilting rotation and eccentric rotation, thereby realizing the reciprocating swing motion of the second massage component 25 (which is a reciprocating swing motion in the front, back and left and right when viewed from above).

[0108] The second rotation limiting part 31 restricts the second annular fitting part 30 from rotating together with the second rotating boss member 29. The second rotation limiting part 31 is provided at a lower position than the rotation axis 21. The second rotation limiting part 31 has a downward-facing limiting pin 33 and a limiting groove 34 into which the limiting pin 33 is slidably inserted.

[0109] The limiting pin 33 is a cylindrical protrusion that protrudes downwards from the base end of the second massage member 25a on the left side (below the second annular fitting portion 30). The limiting groove 34 is a groove that extends in the front-rear direction and is installed on the bottom of the housing 2. This limiting groove 34 is located below the limiting pin 33. The limiting pin 33 is inserted into the limiting groove 34 in a manner that allows it to slide freely in the front-rear direction.

[0110] The massager 1 of this embodiment has an axis angle detection unit 35 for detecting the rotation angle of the rotating axis 21 and a control unit 7 for controlling the drive of the first massage unit 4 and the second massage unit 5.

[0111] A shaft angle detection unit 35 is provided at the rear end of the rotating shaft 21 to detect the rotation angle of the rotating shaft 21. Furthermore, a rotary encoder or similar device can be used as the shaft angle detection unit 35.

[0112] When the axis angle detection unit 35 swings the left and right pair of first massage members 11 and the left and right pair of second massage members 25, if the rotation angle of the rotating axis 21 becomes a predetermined rotation angle, it detects its position.

[0113] The detected position (predetermined rotation angle) is shown as follows: a pair of left and right first massage members 11 clamp the palm P (first treatment part) from the left and right directions, and a pair of left and right second massage members 25 clamp the finger F (second treatment part) from the left and right directions.

[0114] If the control unit 7 receives a signal indicating the detected position, it recognizes that each massage component 11, 25 is clamping the hand H, and maintains the clamping state until the first massage component 4 and the second massage component 5 separate in the front-back direction and reach a predetermined position (the most separated position). That is, the first massage component 4 and the second massage component 5 extend the hand H in the front-back direction.

[0115] If the first massage unit 4 and the second massage unit 5 separate in the front-back direction and reach a predetermined position (the most separated position), the control unit 7 separates each massage component 11, 25 and releases the hand H from the clamped state.

[0116] [Usage Plan]

[0117] Here, the usage of the massager 1 of the present invention will be described.

[0118] like Figure 1 As shown, the massager 1 is placed on a flat and safe surface such as a table. The user inserts their hand H into the insertion recess 3 located on the outer casing 2. The power is turned on by operating the switch 9 located on the lower front side of the massager 1.

[0119] According to the instructions of the control unit 7, the drive unit 6 is driven. That is, the drive motor 23 of the drive unit 6 outputs rotational driving force, which is transmitted to the rotating shaft 21 through the gearbox 24.

[0120] If the rotating shaft 21 rotates, the first rotating boss member 15 rotates and slides within the first annular fitting portion 16. That is, the rotational driving force of the rotating shaft 21 is converted into a reciprocating oscillating motion in the front-back and left-right directions by the first oscillation conversion portion 14. The first massage member 11 performs a reciprocating oscillating motion in the front-back and left-right directions by the conversion of the first oscillation conversion portion 14. The first massage portion 4 oscillates the left and right pairs of first massage members 11 as a unit in the front-back direction.

[0121] Additionally, if the rotating shaft 21 rotates, the second rotating boss member 29 rotates and slides within the second annular fitting portion 30. That is, the rotational driving force of the rotating shaft 21 is converted into a reciprocating oscillating motion in the front-back and left-right directions by the second oscillation conversion portion 28. The second massage member 25 performs a reciprocating oscillating motion in the front-back and left-right directions by the conversion of the second oscillation conversion portion 28.

[0122] The second massage unit 5 swings in the front-to-back direction as a unit, with the pair of second massage components 25 on the left and right. That is, the first massage unit 4 and the second massage unit 5 move towards and away from each other in the front-to-back direction.

[0123] The first swing conversion unit 14 and the second swing conversion unit 28 synchronize the reciprocating swing motion, transforming it into a swing motion that repeatedly approaches and separates the first massage unit 4 and the second massage unit 5 in the front-back direction, and a swing motion that repeatedly clamps and releases the left and right pairs of first massage components 11 and second massage components 25 in the left and right directions.

[0124] like Figure 4 As shown, with the first massage unit 4 clamping the palm P (first treatment unit) and the second massage unit 5 clamping the finger F (second treatment unit), the first massage unit 4 and the second massage unit 5 move in a direction that separates from each other in the front-back direction, and perform a stretching action that pulls the palm P and the finger F (hand H) in the front-back direction.

[0125] Specifically, when the first massage part 4 and the second massage part 5 approach each other in the front-back direction and reach a predetermined position, the left and right pair of first massage parts 11 approach each other and clamp the palm part P (first treatment part) from the left and right directions, and the left and right pair of second massage parts 25 approach each other and clamp the finger part F (second treatment part) from the left and right directions.

[0126] Here, the axis angle detection unit 35 detects the predetermined rotation angle of the rotating axis 21. If the control unit 7 receives the detection signal, it recognizes that each massage component 11, 25 is clamping the hand H (palm P, fingers F).

[0127] The first massage unit 4 and the second massage unit 5 are maintained in a clamped state by the control unit 7 until they separate in the front-back direction and reach a predetermined position (the position where they are most separated in the front-back direction). That is, the first massage unit 4 and the second massage unit 5 pull the hand H in the front-back direction to perform a stretching action.

[0128] When the first massage unit 4 and the second massage unit 5 separate in the front-back direction and reach a predetermined position (the position where they are most separated in the front-back direction), the axis angle detection unit 35 detects the predetermined rotation angle of the rotation axis 21. If the control unit 7 receives a detection signal, it separates the left and right pairs of first massage members 11 and the left and right pairs of second massage members 25, releasing the hand H from its clamped state.

[0129] In short, for example, such as Figure 3 As shown by the arrow, when the first massage part 4 and the second massage part 5 are closest in the front-back direction, the pair of first massage members 11 on the left and right clamp the palm part P and perform a pressing massage, and the pair of second massage members 25 on the left and right clamp the finger part F and perform a pressing massage.

[0130] With the palm P and fingers F clamped in, the first massage part 4 and the second massage part 5 are separated in the front-back direction, thereby extending the hand H in the front-back direction.

[0131] If the first massage part 4 and the second massage part 5 reach the most separated position, then repeat the following: separate the left and right pairs of first massage parts 11 to release the palm part P, and separate the left and right pairs of second massage parts 25 to release the finger part F.

[0132] According to the present invention, the massager 1 can clamp the user's hand H and perform kneading massage and stretching movements, and can be used regardless of the size of the hand H, so as to effectively massage the user.

[0133] That is, the massager 1 of the present invention, like a hand massage performed by a masseur, can not only perform pressure massage, but also simultaneously perform massage on the hand H (palm P, fingers F, etc.) such as grasping and stretching along the length direction (kneading massage and stretching action), thus it can perform massage very effectively.

[0134] [Second Implementation]

[0135] A second embodiment of the massager 1 according to the present invention will be described.

[0136] exist Figures 8 to 12 The diagram shows an overview and device configuration of a second embodiment of the massager 1 according to the present invention.

[0137] Therefore, when using the massager 1 for massage, for example, sometimes it is also desired to treat other parts of the body, such as the forearm A (third treatment area) which is the part from the elbow to the hand H (wrist).

[0138] In this embodiment, the massager 1 can massage not only the palm P (first treatment area) or fingers F (second treatment area) of the hand H, but also the forearm A (third treatment area). In this embodiment, massage of the forearm A is illustrated as an example. Furthermore, the massager 1 of this embodiment can also massage the palm P or fingers F of the hand H.

[0139] The basic structure of the massager 1 according to this embodiment is largely the same as that of the first embodiment. Therefore, detailed description is omitted.

[0140] That is, the basic structure of the first massage unit 4, the second massage unit 5, the drive unit 6, the first massage component 11, the first swing conversion unit 14, the rotation axis 21, the second massage component 25, the second swing conversion unit 28, the axis angle detection unit 35, etc., is roughly the same as that of the first embodiment.

[0141] As a difference between this embodiment and the first embodiment, the left-right spacing between the pair of first massage members 11 and the left-right spacing between the pair of second massage members 25 can be widened. Therefore, the forearm portion A, which is larger than the hand portion H, can also be inserted into the first massage portion 4 and the second massage portion 5.

[0142] like Figures 8 to 12 As shown, the first swing conversion unit 14 in this embodiment has a first rotating boss member 15 that rotates integrally with the rotating shaft 21 and a first annular fitting part 16 that is embedded in the outer periphery of the first rotating boss member 15.

[0143] Furthermore, in this embodiment, a first link member 36 is provided, which is arranged in a horizontal direction and outward relative to the rotation axis 21, and its end is connected to the middle part of the first massage member 11 in the longitudinal direction.

[0144] The first massage member 11 in this embodiment has a different shape than that in the first embodiment. That is, the first massage member 11 is a long strip that extends upwards. The first massage member 11 has a fan shape that expands outwards in a flat shape at the top. At the end (upper end) of the first massage member 11, for example, a first treatment member 12 is provided for pressing and massaging the forearm portion A (the third treatment portion).

[0145] At the base (lower end) of the first massage member 11, a hole 38 is formed into which a pin member 37, which is rotatably supported, is inserted. That is, in this embodiment, the base (lower end) of the first massage member 11 does not have a first annular fitting portion 16.

[0146] At the midpoint of the length direction of the first massage member 11, a hole 40 is formed into which a pin member 39, which is rotatably supported, is inserted.

[0147] In this embodiment, a first connecting rod member 36 is provided between the first massage member 11 and the first rotating boss member 15. The first connecting rod member 36 is configured such that its end faces outward in the left-right direction (horizontal direction). At the end of the first connecting rod member 36, a hole 41 is formed into which a pin member 39, which is rotatably supported, is inserted.

[0148] On the other hand, a first annular fitting portion 16 is provided on the base end side of the first connecting rod member 36. That is, the first connecting rod member 36 has a shape that tapers from the base end toward the end.

[0149] In this embodiment, two first link components 36 are provided at the front and rear.

[0150] The first link member 36a on the left side is provided on the rear side of the first rotating boss member 15a. The first link member 36a engages with the hole 41a formed in the middle of the length direction of the first massage member 11a on the left side and inserts the pin member 39 to rotatably support the first massage member 11a on the left side.

[0151] In addition, the first annular fitting portion 16a located at the base end of the first connecting rod member 36a is externally fitted into the first rotating boss member 15a.

[0152] The first link member 36b on the right side is provided on the front side of the first rotating boss member 15b. The first link member 36b engages with the hole 41b and the hole 40b formed in the middle of the length direction of the first massage member 11b on the right side and inserts the pin member 39 to rotatably support the first massage member 11b on the right side.

[0153] In addition, the first annular fitting portion 16b located at the base end of the first connecting rod member 36b is externally fitted into the first rotating boss member 15b.

[0154] The first rotating boss member 15 of this embodiment has a different shape than that of the first embodiment. That is, in this embodiment, the first rotating boss members 15a and 15b are integrally formed. The axial direction of the first rotating boss members 15a and 15b is eccentric relative to the axial direction of the rotating shaft 21. In addition, the first cam surface 18a formed on the first rotating boss member 15a and the first cam surface 18b formed on the first rotating boss member 15b are inclined in the same direction.

[0155] In this embodiment, in the legend (e.g., Figure 9 In the first rotating boss components 15a and 15b, the first rotating boss components 15a and 15b are arranged in the left-front direction relative to the axis of rotation 21. In addition, the first cam surfaces 18a and 18b are arranged in the left-rear direction relative to the axis of rotation 21.

[0156] The first rotating boss components 15a and 15b rotate with respect to the rotation axis 21, and undergo tilting and eccentric rotation.

[0157] In this embodiment, the first rotating boss member 15a is positioned further forward than the first connecting rod member 36a on the left. Furthermore, the first rotating boss member 15b is positioned further rearward than the first connecting rod member 36b on the right.

[0158] At the center of the first rotating boss component 15, there is a flange portion 44 that is embedded into the hole portion 43 of the support component 42. That is, the first rotating boss component 15 is rotatably supported by the support component 42.

[0159] In this embodiment, a support member 42 is provided, through which the rotating shaft 21 passes and supports the first rotating boss member 15. The support member 42 is a plate-shaped member with a hole 43 formed in its upper part. The hole 43 is used to externally fit the flange portion 44 of the first rotating boss member 15. The support member 42 is rotatably supported at the base ends of the left and right pair of first massage members 11.

[0160] A groove 45, elongated in the left-right direction, is formed at the lower part of the support member 42. A generally rectangular block 46 is provided in the groove 45. A hole 47 is formed in the block 46 for the pin member 37 to be inserted. A pair of holes are provided on the left and right sides of the block 46.

[0161] The left block 46a engages with the hole 47a in the hole 38a formed in the first massage member 11a on the left side and inserts the pin member 37, thus rotatably supporting the lower end of the first massage member 11a on the left side.

[0162] The block 46b on the right side engages with the hole 47b in the hole 38b formed in the first massage member 11b on the right side and inserts the pin member 37, thus rotatably supporting the lower end of the first massage member 11b on the right side.

[0163] Furthermore, in this embodiment, the portion of the block 46 that is located on the outer side in the left-right direction is significantly chamfered in order to release the force caused by the inertia generated by the swing of the first massage member 11.

[0164] The position of the first annular fitting portion 16 in this embodiment differs from that in the first embodiment. Specifically, the first annular fitting portion 16 is located at the base end of the first connecting rod member 36. The first annular fitting portion 16a is located on the rear side of the first rotating boss member 15a. Furthermore, the first annular fitting portion 16b is located on the front side of the first rotating boss member 15b.

[0165] In this embodiment, in the legend (e.g., Figure 9 In the first annular fitting parts 16a and 16b, like the first rotating boss part 15, they are arranged in the left-front direction relative to the axis of rotation 21.

[0166] Furthermore, in this embodiment, the first annular fitting portion 16a located at the base end of the first connecting rod member 36a on the left side externally fits the first rotating boss member 15a. Additionally, the first annular fitting portion 16a is configured to be clamped by the pressing member 15c.

[0167] The first annular fitting portion 16b, located at the base end of the first connecting rod member 36b on the right side, externally fits the first rotating boss member 15b. Furthermore, the first annular fitting portion 16b is configured to be clamped by the pressing member 15d.

[0168] The first rotating boss component 15 with the inclined first cam surface 18 and the first annular fitting portion 16 embedded therein transform the rotational driving force of the rotating shaft 21 into tilting rotation and eccentric rotation, thereby realizing the reciprocating swing motion of the first massage component 11 (which is a reciprocating swing motion in the front, back and left and right when viewed from above).

[0169] Furthermore, in this embodiment, a first elastic member 48 is provided on the base end side of the first massage member 11 in a horizontally laid-flat manner. In this embodiment, the first elastic member 48 is a spring member (coil spring).

[0170] The first spring member 48 is disposed on the base end sides of a pair of first massage members 11 in a manner sandwiched from the left and right. More specifically, the first spring member 48 is disposed on the lower part of the support member 42. The first spring member 48 is disposed in a horizontally extending groove 45 formed in the lower part of the support member 42. More specifically, the first spring member 48 is disposed sandwiched between a left-side block 46a and a right-side block 46b disposed within the extended groove 45.

[0171] That is, the pair of first massage components 11a and 11b move outward in the left and right directions, thereby causing the first spring component 48 on the base side to contract, thereby widening the gap between the pair of first massage components 11 in the left and right directions.

[0172] Specifically, if the ends of the left and right pair of first massage members 11a and 11b are moved in a direction that separates them (outward in the left and right direction), the left first massage member 11a rotates around the end of the first link member 36a, and the right first massage member 11b rotates around the end of the first link member 36b, thereby causing the first spring member 48, which is mounted horizontally, to contract. As a result, the distance between the left and right pairs of first massage members 11a and 11b in the left and right direction is greatly widened, and the forearm part A (third treatment part), which is larger than the palm part P (first treatment part) or finger part F (second treatment part) of the hand H, can also be inserted.

[0173] Furthermore, the stiffness (spring constant) of the first spring component 48 can be designed to ensure that it does not cause discomfort to the inserted treatment area.

[0174] In this embodiment, the first rotation limiting part 17 is provided at the lower part of the support member 42. The first rotation limiting part 17 restricts the first annular fitting part 16 from rotating together with the first rotating boss member 15 via the support member 42. The first rotation limiting part 17 has a limiting pin 19 provided from the lower side of the groove part 45 toward the bottom and a limiting groove provided at the bottom of the housing 2 into which the limiting pin 19 slides freely.

[0175] Furthermore, on the upper side of the first swing conversion section 14 in this embodiment, a cover member 62 is provided to prevent the entry of the treatment part inserted into the insertion recess 3.

[0176] like Figures 8 to 12 As shown, the second swing conversion part 28 has a second rotating boss member 29 that rotates integrally with the rotating shaft 21 and a second annular fitting part 30 that is embedded in the outer periphery of the second rotating boss member 29.

[0177] Furthermore, in this embodiment, a second linkage member 49 is provided, which is arranged in a horizontal direction and outward relative to the rotation axis 21, and its end is connected to the middle part of the second massage member 25 in the length direction.

[0178] The second massage member 25 in this embodiment has a different shape than that in the first embodiment. Specifically, the second massage member 25 is an elongated member that extends upwards. The second massage member 25 has a fan shape with its upper part expanding in a flat, plate-like manner. At the end (upper end) of the second massage member 25, for example, a second treatment member 26 is provided for pressing and massaging the forearm portion A (the third treatment portion).

[0179] At the base (lower end) of the second massage member 25, a hole 51 is formed into which a pin member 50, which is rotatably supported, is inserted. In addition, at the midpoint of the length direction of the second massage member 25, a hole 53 is formed into which a pin member 52, which is rotatably supported, is inserted.

[0180] In this embodiment, a second connecting rod member 49 is provided between the second massage member 25 and the second rotating boss member 29. The second connecting rod member 49 is configured such that its end faces outward in the left-right direction (horizontal direction). At the end of the second connecting rod member 49, a hole 54 is formed for insertion into a pin member 52 that is rotatably supported.

[0181] On the other hand, a second annular fitting portion 30 is provided on the base end side of the second connecting rod member 49. That is, the second connecting rod member 49 has a shape that tapers from the base end toward the end.

[0182] In this embodiment, two second link components 49 are provided at the front and rear.

[0183] The second link member 49a on the left is provided on the front side of the first rotating boss member 15a. The second link member 49a engages with the hole 54a and the hole 53a formed in the middle of the length direction of the first massage member 11a on the left, and inserts the pin member 52 to rotatably support the first massage member 11a on the left.

[0184] In addition, the second annular fitting portion 30a, located at the base end of the second connecting rod member 49a, is externally fitted into the second rotating boss member 29a.

[0185] The second link member 49b on the right side is located on the rear side of the second rotating boss member 29b. The second link member 49b engages with the hole 54b and the hole 53b formed in the middle of the length direction of the first massage member 11b on the right side, and inserts the pin member 52 to rotatably support the first massage member 11b on the right side.

[0186] Additionally, the second annular fitting portion 30b, located at the base end of the second connecting rod member 49b, is externally fitted into the second rotating boss member 29b.

[0187] The second rotating boss member 29 of this embodiment has a different shape than that of the first embodiment. That is, in this embodiment, the second rotating boss members 29a and 29b are integrally formed. The axial direction of the second rotating boss members 29a and 29b is eccentric relative to the axial direction of the rotating shaft 21. In addition, the second cam surface 32a formed on the second rotating boss member 29a and the second cam surface 32b formed on the second rotating boss member 29b are inclined in the same direction.

[0188] In this embodiment, in the legend (e.g., Figure 9 In the aforementioned configuration, the second rotating boss components 29a and 29b are arranged with their axes of rotation 21 facing to the right front direction. Additionally, the second cam surfaces 32a and 32b are arranged with their axes of rotation 21 facing to the right rear direction.

[0189] The second rotating boss components 29a and 29b rotate with respect to the rotation axis 21, and undergo tilting and eccentric rotation.

[0190] In this embodiment, the second rotating boss member 29a is positioned further rearward than the second link member 49a on the left. Furthermore, the second rotating boss member 29b is positioned further forward than the second link member 49b on the right.

[0191] At the center of the second rotating boss component 29, there is a flange portion 57 that is embedded into the hole portion 56 of the support component 55. That is, the second rotating boss component 29 is rotatably supported by the support component 55.

[0192] In this embodiment, a support member 55 is provided, through which the rotating shaft 21 passes and supports the second rotating boss member 29. The support member 55 is a plate-shaped member with a hole 56 formed in its upper part. The hole 56 is used to externally fit the flange portion 57 of the second rotating boss member 29. The support member 55 is rotatably supported at the base ends of the left and right pair of second massage members 25.

[0193] A groove 58, elongated in the left-right direction, is formed at the lower part of the support member 55. A generally rectangular block 59 is provided in the groove 58. A hole 60 is formed in the block 59 for the pin member 50 to be inserted. A pair of holes are provided on the left and right sides of the block 59.

[0194] The left block 59a engages with the hole 60a with the hole 51a formed in the second massage member 25a on the left and inserts the pin member 50, thus rotatably supporting the lower end of the second massage member 25a on the left.

[0195] The block 59b on the right side engages with the hole 60b in the hole 51b formed in the second massage member 25b on the right side and inserts the pin member 50, thus rotatably supporting the lower end of the second massage member 25b on the right side.

[0196] Furthermore, in this embodiment, the portion of the block 59 that is located on the outer side in the left-right direction is significantly chamfered in order to release the force caused by the inertia generated by the swing of the second massage member 25.

[0197] The location of the second annular fitting portion 30 in this embodiment differs from that in the first embodiment. Specifically, the second annular fitting portion 30 is formed at the base end of the second connecting rod member 49. The second annular fitting portion 30a is provided on the front side of the second rotating boss member 29a. Furthermore, the second annular fitting portion 30b is provided on the rear side of the second rotating boss member 29b.

[0198] In this embodiment, in the legend (e.g., Figure 9 In the second annular fitting parts 30a and 30b, the second rotating boss part 29 is similarly positioned in the right-front direction relative to the axis of rotation 21.

[0199] Furthermore, in this embodiment, the second annular fitting portion 30a, located at the base end of the second connecting rod member 49a on the left side, externally fits the second rotating boss member 29a. Additionally, the second annular fitting portion 30a is configured to be clamped by the pressing member 29c.

[0200] The second annular fitting portion 30b, located at the base end of the second connecting rod member 49b on the right side, externally fits the second rotating boss member 29b. Furthermore, the second annular fitting portion 30b is configured to be clamped by the pressing member 29d.

[0201] The second rotating boss component 29 with the inclined second cam surface 32 and the second annular fitting portion 30 embedded therein transform the rotational driving force of the rotating shaft 21 into tilting rotation and eccentric rotation, thereby realizing the reciprocating swing motion of the second massage component 25 (which is a reciprocating swing motion in the front, back and left and right when viewed from above).

[0202] Furthermore, in this embodiment, a second elastic member 61 is provided on the base end side of the second massage member 25 in a horizontally laid-flat manner. In this embodiment, the second elastic member 61 is a spring member (coil spring).

[0203] The second spring member 61 is mounted on the base ends of a pair of second massage members 25 in a manner sandwiched from the left and right. More specifically, the second spring member 61 is mounted on the lower part of the support member 55. The second spring member 61 is mounted horizontally in a groove 58 formed in the lower part of the support member 55, which extends in the left and right direction. More specifically, the second spring member 61 is mounted sandwiched between a left-side block 59a and a right-side block 59b disposed within the extended groove 58.

[0204] That is, the pair of second massage components 25a and 25b move outward in the left and right directions, thereby causing the second spring component 61 on the base side to contract, thereby widening the gap between the pair of second massage components 25 in the left and right directions.

[0205] Specifically, if the ends of the pair of second massage members 25a and 25b are moved in a direction separating them (outward in the left-right direction), the left second massage member 25a rotates around the end of the second link member 49a, and the right second massage member 25b rotates around the end of the second link member 49b. The second spring member 61, which is horizontally mounted, contracts, thus greatly widening the distance between the pair of second massage members 25a and 25b in the left-right direction, allowing the forearm part A (third treatment part), which is larger than the palm part P (first treatment part) or finger part F (second treatment part) of the hand H, to be inserted.

[0206] Furthermore, the stiffness (spring constant) of the second spring component 61 can be adjusted to ensure that it does not cause discomfort to the inserted treatment area.

[0207] In this embodiment, the second rotation limiting part 31 is provided at the lower part of the support member 55. The second rotation limiting part 31 restricts the second annular fitting part 30 from rotating together with the second rotating boss member 29 via the support member 55. The second rotation limiting part 31 has a limiting pin 33 provided downward from the lower side of the groove 58 and a limiting groove provided at the bottom of the housing 2 into which the limiting pin 33 slides freely.

[0208] Furthermore, on the upper side of the second swing conversion section 28 in this embodiment, a cover member 62 is provided to prevent the treatment section inserted into the insertion recess 3 from entering.

[0209] [Usage Plan]

[0210] Here, the usage of the massager 1 of the present invention will be described.

[0211] like Figure 1 As shown, the massager 1 is placed on a flat and safe surface such as a table. The user inserts the forearm part A (the third treatment part) into the insertion recess 3 provided in the outer casing 2.

[0212] Specifically, while applying force, the forearm part A is inserted from above into the insertion recess 3. As the forearm part A is pressed in, the ends of the pair of first massage components 11a and 11b move laterally in the left and right directions.

[0213] That is, the first massage member 11a on the left rotates about the end of the first connecting rod member 36a (around the pin member 39), and the first massage member 11b on the right rotates about the end of the first connecting rod member 36b (around the pin member 39). As a result, the first spring member 48, which is horizontally mounted, retracts, causing the block 46a on the left, which is disposed in the longer groove 45 formed in the support member 42, to move to the right, and the block 46b on the right to move to the left.

[0214] At the base end of the first massage member 11, the first spring member 48, sandwiched between the left and right blocks 46a and 46b, contracts due to the compression of the blocks 46a and 46b. As a result, the distance between the left and right pairs of first massage members 11a and 11b in the left and right directions widens significantly, allowing the forearm portion A to be inserted.

[0215] Similarly, by pressing into the forearm part A, the ends of the pair of second massage components 25a and 25b move laterally to the left and right.

[0216] That is, the second massage member 25a on the left rotates about the end of the second connecting rod member 49a (around the pin member 52), and the second massage member 25b on the right rotates about the end of the first connecting rod member 49b (around the pin member 52). As a result, the second spring member 61, which is horizontally mounted, retracts, causing the block 59a on the left, which is disposed in the longer groove 58 formed in the support member 55, to move to the right, and the block 59b on the right to move to the left.

[0217] At the base of the second massage component 25, the second spring component 61, sandwiched between the left and right blocks 59a and 59b, contracts due to the compression of the blocks 59a and 59b. As a result, the distance between the left and right pairs of second massage components 25a and 25b in the left-right direction widens significantly, allowing the forearm portion A to be inserted.

[0218] That is, by pressing the forearm part A in, the pair of first massage components 11a and 11b on the left and right and the pair of second massage components 25a and 25b on the left and right simultaneously widen outward in the left and right directions.

[0219] The power is turned on by operating the switch 9 located on the lower front side of the massager 1. The drive unit 6 is driven according to the instructions of the control unit 7. That is, the drive motor 23 of the drive unit 6 outputs rotational driving force, which is transmitted to the rotating shaft 21 via the gearbox 24.

[0220] If the rotating shaft 21 rotates, the first rotating boss member 15 rotates and slides within the first annular fitting portion 16. The first connecting rod member 36 transmits the transformed reciprocating oscillating motion to the first massage member 11.

[0221] That is, the rotational driving force of the rotating shaft 21 is converted into a reciprocating oscillating motion in the front-back and left-right directions by the first oscillating conversion unit 14. The first massage component 11 performs a reciprocating oscillating motion in the front-back and left-right directions via the first connecting rod component 36 through the conversion of the first oscillating conversion unit 14. The first massage components 4 oscillate relative to each other in the front-back direction.

[0222] Additionally, if the rotating shaft 21 rotates, the second rotating boss member 29 rotates and slides within the second annular fitting portion 30. The second connecting rod member 49 transmits the modified reciprocating oscillating motion to the second massage member 25.

[0223] That is, the rotational driving force of the rotating shaft 21 is converted into a reciprocating swing motion in the front, back, left, and right directions by the second swing conversion unit 28. The second massage component 25 performs a reciprocating swing motion in the front, back, left, and right directions via the second linkage component 49 through the conversion of the second swing conversion unit 28.

[0224] The second massage section 5 swings in the front-to-back direction. That is, the first massage section 4 and the second massage section 5 move towards and separate from each other in the front-to-back direction.

[0225] The first swing conversion unit 14 and the second swing conversion unit 28 synchronize the reciprocating swing motion, transforming it into a swing motion that repeatedly approaches and separates the first massage unit 4 and the second massage unit 5 in the front-back direction, and a swing motion that repeatedly clamps and releases the left and right pairs of first massage components 11 and second massage components 25 in the left and right directions.

[0226] like Figure 9 As shown, with the first massage unit 4 clamping the forearm A (the side near the elbow) and the second massage unit 5 clamping the forearm A (the side near the wrist), the first massage unit 4 and the second massage unit 5 move in a direction that is separated from each other in the front-back direction, and perform a stretching action that pulls the forearm A as a whole in the front-back direction.

[0227] Specifically, when the first massage part 4 and the second massage part 5 approach each other in the front-back direction and reach a predetermined position, the left and right pair of first massage parts 11 approach each other and clamp the forearm part A (the side near the elbow) from the left and right directions, and the left and right pair of second massage parts 25 approach each other and clamp the forearm part A (the side near the wrist) from the left and right directions.

[0228] Here, the axis angle detection unit 35 detects the predetermined rotation angle of the rotating axis 21. If the control unit 7 receives the detection signal, it recognizes that the first massage member 11 and the second massage member 25 are clamping the forearm part A as a whole.

[0229] The first massage unit 4 and the second massage unit 5 are maintained in a clamped state by the control unit 7 until they separate in the front-back direction and reach a predetermined position (the most separated position). That is, the first massage unit 4 and the second massage unit 5 extend the forearm part A as a whole in the front-back direction.

[0230] When the first massage unit 4 and the second massage unit 5 separate in the front-back direction and reach a predetermined position (the most separated position), the axis angle detection unit 35 detects the predetermined rotation angle of the rotation axis 21. If the control unit 7 receives a detection signal, it separates the left and right pair of first massage members 11 and the left and right pair of second massage members 25, releasing the forearm part A from its clamped state.

[0231] In short, for example, such as Figure 9 As indicated by the arrow, when the first massage part 4 and the second massage part 5 are closest in the front-back direction, the pair of first massage members 11 on the left and right clamp the forearm part A (the side near the elbow) and perform a pressing massage, and the pair of second massage members 25 on the left and right clamp the forearm part A (the side near the wrist) and perform a pressing massage.

[0232] With the forearm A clamped in, the first massage part 4 and the second massage part 5 are separated in the front-back direction, causing the forearm A to extend as a whole in the front-back direction.

[0233] If the first massage part 4 and the second massage part 5 reach the most separated position, the following is repeated: the left and right pairs of first massage parts 11 are separated to release the forearm part A (the side near the elbow), and the left and right pairs of second massage parts 25 are separated to release the forearm part A (the side near the wrist).

[0234] According to the massager 1 of the present invention, the user's forearm A can be clamped in and kneaded and stretched, and can be used regardless of the size of the forearm A (hand H) to effectively massage the user.

[0235] That is, the massager 1 of the present invention, like a hand massage performed by a masseur, expands the distance between the left and right pairs of first massage members 11 and second massage members 25, except for the hand H (palm P, fingers F, etc.), so that the forearm A can not only be pressed and massaged, but also massaged by grasping and stretching along the length direction (kneading massage and stretching action), thus making the massage very effective.

[0236] Furthermore, the embodiments disclosed herein should be considered illustrative rather than restrictive in all respects.

[0237] In particular, in the embodiments disclosed herein, undisclosed matters (e.g., working conditions or operating conditions, dimensions of the components, weight, etc.) do not depart from the scope of what is commonly practiced by those skilled in the art, and are matters that would be easily conceived by those skilled in the art in ordinary practice.

[0238] For example, the length of the first massage member 11 provided in the first massage unit 4, or the tilt angle and eccentric position of the first massage member 11 (the first cam surface 18 of the first rotating boss member 15) relative to the rotation axis 21, and the separation distance of the left and right first massage members 11, can be appropriately changed according to the treatment range (e.g., the size of the palm P, the hand H, or the forearm A).

[0239] Similarly, the length of the second massage member 25 provided in the second massage unit 5, or the tilt angle and eccentric position of the second massage member 25 (the second cam surface 32 of the second rotating boss member 29) relative to the rotation axis 21, and the separation distance of the left and right second massage members 25 can be appropriately changed according to the treatment range (e.g., the size of the hand H such as the finger F or the forearm A).
