[0045] Preferred embodiments of the present invention are as follows.

[0046] [1] The massage device of the present invention comprises: a scraping part having an edge part and at least a first face part and a second face part; and a grip part provided on a surface of one of the first face part and the second face part and extending in a direction intersecting with the surface of one of the first face part and the second face part. With such a configuration, it is easy to apply force to the scraping part while the scraping part is pressed against a treatment area, so that the body can be massaged and relaxed effectively.

[0047] [2] The massage device described in [1] above comprises: a shaft located on the opposite side of the holding portion relative to the imaginary plane along the edge portion, the shaft extending in a direction intersecting the surface of either the first face portion or the second face portion; and a rotating body rotatably supported on the shaft, the rotating body being located outside the edge portion when viewed from a direction perpendicular to the imaginary plane, and being located outside the edge portion when viewed from a direction perpendicular to the imaginary plane. According to such a configuration, both the rotating body and the scraping portion can simultaneously touch the treatment area for massage, thereby effectively kneading and relaxing the body.

[0048] [3] In the massage device described in [2] above, the rotating body, the scraping part and the holding part may be arranged in the order from front to back. According to such a structure, it is easy to push both the rotating body and the scraping part against the treatment area at the same time, so that the body can be massaged and relaxed effectively.

[0049] [4] In the massage device described in [2] or [3] above, the scraping part may be arranged at the top and the rotating body at the bottom, with the holding part as a reference. According to such a structure, it is easy to apply force to both the rotating body and the scraping part when both the rotating body and the scraping part are pushed against the treatment area, thereby effectively kneading and relaxing the body.

[0050] [5] In the massage apparatus described in [2] to [4] above, the rotating body may be provided with a pair of left and right rotating bodies, and the scraping part may have left and right edge parts adjacent to the left and right rotating bodies. According to such a configuration, both the rotating body and the scraping part can simultaneously touch the treatment part for massage, regardless of whether it is on the left or right side of the massage apparatus, so that the direction of the massage apparatus can be changed to effectively massage and relax various parts of the body.

[0051] [6] The massage device comprises: a main body; a shaft extending outward from the main body; a rotating body rotatably supported on the shaft; and a protrusion protruding outward from the main body for pressing the body, wherein the shaft and the rotating body are provided in a pair, and the pair of rotating bodies and the protrusion can contact the treatment area at the same time. According to such a configuration, the treatment area that is pinched and pushed by the pair of rotating bodies can be pressed by the protrusion for pressing the body. Furthermore, the treatment area that is pressed by the protrusion for pressing the body can be pinched and pushed by the pair of rotating bodies. Therefore, the body can be effectively massaged and relaxed.

[0052] [7] In the massage device described in [6] above, it is also possible that, in a side view observed from the arrangement direction of the pair of rotating bodies, the angle formed by the plane tangent to the three points of the pair of rotating bodies and the protrusion and the rotation axis of the rotating body is greater than 0 degrees and less than 110 degrees. According to such a structure, the treatment area that is sometimes pinched and sometimes pushed by the pair of rotating bodies can be pressed by the protrusion for body pressing. Moreover, the treatment area pressed by the protrusion for body pressing can be sometimes pinched and sometimes pushed by the pair of rotating bodies. Therefore, the body can be effectively massaged and relaxed.

[0053] [8] In the massage device described in [6] or [7] above, the protrusion may be provided in plurality. According to such a configuration, the treatment area can be pressed by the plurality of protrusions, thereby effectively kneading and relaxing the body.

[0054] [9] In the massage device described in [8] above, the plurality of protrusions may be of different sizes. According to such a configuration, the pressing method of the treatment area can be changed by the plurality of protrusions of different sizes, so that the body can be massaged and relaxed effectively.

[0055]

[10] In the massage device described in [9] above, the plurality of protrusions may be arranged behind the pair of rotating bodies and arranged in order from the largest protrusion to the rear. According to such a configuration, the massage device can be moved forward or backward to continuously perform the treatment based on the pair of rotating bodies and the treatment based on the plurality of protrusions.

[0056]

[11] In the massage device described in [6] to

[10] above, the main body may include a grip portion to be gripped by a user and an extension portion extending downward from the grip portion, and the protrusion may be provided on the extension portion. According to such a configuration, the protrusion may be arranged at a position where it will not get in the way when the user grips the grip portion.

[0057] <Example>

[0058] Below, refer to Figures 1 to 19 An embodiment of the present invention is described in detail. The massage device 10 in this embodiment is mainly used for massaging the body. Figure 1 and Figure 2 As shown, the massage device 10 includes a main body 11, a pair of rotating bodies 12, a scraping part 13, and protrusions (large protrusions 14 and small protrusions 15) for pressing the body.

[0059] In the following, in each component, the upper side in the state where the pair of rotating bodies 12 and the large protrusion 14 simultaneously hit the horizontal plane H is referred to as the upper side, the lower side as the lower side, the rotating body 12 side as the front side, the side opposite to the rotating body 12 as the rear side, the right side when viewed from the rear side to the front side in the state of standing vertically to the horizontal plane H as the right side, and the left side as the left side. In each figure, the positive direction side of the X axis represents the front side, the negative direction side of the X axis represents the rear side, the positive direction side of the Y axis represents the upper side, the negative direction side of the Y axis represents the lower side, the positive direction side of the Z axis represents the right side, and the negative direction side of the Z axis represents the left side. The state where the pair of rotating bodies 12 and the large protrusion 14 simultaneously hit the horizontal plane H is referred to as the loading state.

[0060] like Figure 1 As shown, the main body 11 includes a bifurcated portion 16, a grip portion 17, and an extended portion 18. The bifurcated portion 16 is provided at the front end of the main body 11. The grip portion 17 is provided behind the bifurcated portion 16. The grip portion 17 is formed in a cylindrical shape extending in the front-rear direction.

[0061] The upper surface of the grip 17 is inclined upward from the front side toward the rear side in the loading state. In the side view of the massage device 10 viewed from the left and right directions, at least a portion of the grip 17 is located on the horizontal plane H side relative to the extension line of the rotation axis R of the rotating body 12. With such a configuration, it is possible to press the skin while changing between pinching and pushing without having to twist the arm holding the grip 17 greatly or turning the hand over, thereby realizing a massage device 10 with good operability. The size of the grip 17 in the vertical direction gradually decreases from the front side toward the rear side.

[0062] The length dimension 17L of the gripping portion 17 is, for example, 100 mm. The length dimension 17L of the gripping portion 17 is the length dimension of the upper edge of the gripping portion 17 when observing the massage device 10 from the left and right directions. The length dimension 17L of the gripping portion 17 may be set within a range of 30 mm to 200 mm. The length dimension 17L of the gripping portion 17 is preferably within a range of 50 mm to 170 mm. The length dimension 17L of the gripping portion 17 is further preferably within a range of 80 mm to 150 mm. In this case, the user can easily grip the gripping portion 17, and thus can effectively apply force to the treatment portion.

[0063] The lower part of the grip 17 has a plurality of recesses 19. The plurality of recesses 19 are formed continuously in the front-to-back direction. Each recess 19 is concave in an arc shape that can easily follow the user's fingers. There are five recesses 19, and the gripping method called the front side and the rear side can be adopted, and the force input state can be changed by the gripping method. Figure 2 As shown in FIG. 1 , the dimension of the gripping portion 17 in the left-right direction gradually decreases from the front side toward the rear side. The outer peripheral surface of the gripping portion 17 is curved over the entire circumference in the YZ cross section.

[0064] Although the position of the holding portion 17 is not particularly limited, it is Figure 1 ) is the width of the extreme ends of the rotating body 12 and the scraping part 13, and the holding part 17 extends from a roughly central position. When the holding part 17 extends from a roughly central position, the method of applying force to the scraping part 13 and the rotating body 12 can be made constant, and the force can be applied to the treatment part more effectively. It is not limited to the width of the rotating body 12 and the scraping part 13, and it can also be a roughly central position of the width of the outer edges of the scraping part 13. In this case, the method of applying force can be made constant at any position of the outer edge of the scraping part 13, and the force can be applied to the treatment part more effectively.

[0065] like Figure 3 As shown, the gripping portion 17 includes a shaft portion 21 and a cylindrical portion 22. The shaft portion 21 is a part of a core member 23 described later. The shaft portion 21 is inserted into a through hole 24 formed in the cylindrical portion 22. The through hole 24 penetrates the cylindrical portion 22 in the front-rear direction.

[0066] A bolt 26 is embedded in the shaft-shaped portion 21. The bolt 26 is made of metal such as iron. The bolt 26 extends linearly rearward from the vicinity of the forked portion 16. The rear end portion of the bolt 26 protrudes rearward from the rear end of the grip portion 17.

[0067] The cylindrical portion 22 is formed of a synthetic resin such as ABS resin. The surface of the cylindrical portion 22 may also be covered by a covering portion. The covering portion may also be formed of an elastic material such as rubber or a thermoplastic elastomer. As a thermoplastic elastomer, for example, a polyester system (TPC) may be applied.

[0068] like Figure 1 As shown, the extension portion 18 extends downward from the grip portion 17. The extension portion 18 is formed of a synthetic resin such as ABS resin or aluminum casting (aluminum alloy such as ADC12). The extension portion 18 has a front surface portion 27, a rear surface portion 28, and an extension surface portion 29.

[0069] The front surface portion 27 extends downward from a position forward of the grip portion 17. The front surface portion 27 is inclined rearward from the upper end toward the lower end. The rear surface portion 28 extends downward from a position rearward of the grip portion 17. The rear surface portion 28 is inclined at the same angle as the front surface portion 27. The extended surface portion 29 extends from the lower end of the front surface portion 27 to the lower end of the rear surface portion 28. The extended surface portion 29 is formed in a gently curved shape. The large protrusion 14 and the small protrusion 15 are provided on the extended surface portion 29.

[0070] In the placed state, the rear end of the extended surface 29 is located above the front end of the extended surface 29. A space 31 for inserting a hand is formed between the extended portion 18 and the grip portion 17. By inserting a hand into the space 31 and gripping the grip portion 17, it is possible to easily apply force when massaging the rotating body 12 and the protrusions 14 and 15 for pressing the body, thereby performing effective massage.

[0071] like Fig.14 As shown in FIG. 1 , the left-right dimension of the front surface portion 27 gradually decreases from the upper side to the lower side. The left and right surfaces of the front surface portion 27 are inclined in a manner approaching each other from the upper side to the lower side. Fig.15 As shown in FIG. 1 , the left-right dimension of the rear surface portion 28 is constant in the vertical direction. The left-right dimension of the rear surface portion 28 is the same as the left-right dimension of the extended surface portion 29. Fig.16 As shown, the left-right dimension of the extended surface portion 29 is smaller than the left-right dimension of the grip portion 17. The left-right dimension of the extended surface portion 29 is substantially constant in the front-rear direction.

[0072] like Figure 4As shown, the extension portion 18 has a front connecting portion 32 and a rear connecting portion 33 connected to the grip portion 17. The front connecting portion 32 is provided at the upper end of the front surface portion 27. A hole 34 (see FIG. 2 ) is formed in the front connecting portion 32 for the shaft-shaped portion 21 of the core member 23 to pass through. Figure 3 The shaft-shaped portion 21 of the core member 23 is inserted into the through hole 24 of the cylindrical portion 22 through the hole 34 of the front connecting portion 32. The front connecting portion 32 contacts the front end surface of the grip portion 17.

[0073] The rear connecting portion 33 is provided at the upper end of the rear surface portion 28. A hole 35 is formed in the rear connecting portion 33 for the rear end of the bolt 26 to pass through. The rear connecting portion 33 and the rear end surface of the gripping portion 17 are interposed with a ring 36 to contact the rear end surface of the gripping portion 17 ( Figure 3 The rear end of the bolt 26 is inserted into the hole 35 of the rear connecting portion 33 and fixed to the rear connecting portion 33 via a flat washer 37 and a nylon nut 38. A nut cover 39 is attached to the rear surface of the rear connecting portion 33. The nut cover 39 covers the nylon nut 38.

[0074] like Figure 5 As shown, a pair of rotating bodies 12 are provided at the lower end of the fork portion 16. Each rotating body 12 is substantially spherical. The diameter of the rotating body 12 is 40 mm. Each rotating body 12 rotates around the rotation axis R. Preferably, the opening angle α of the pair of rotation axes R is in the range of 50 to 110 degrees. The opening angle α of the rotation axis R is set to 65 to 80 degrees. Preferably, the opening angle α of the pair of rotation axes R is 70 degrees.

[0075] like Figure 4 and Figure 6 As shown, the support portion 41 supporting the rotating body 12 includes a shaft 42, a graphite nylon washer 43 (Japanese: ポリスライダー), a bearing 44, a bearing washer 45, and an E-ring 46. A pair of the support portions 41 are provided on the left and right.

[0076] A pair of shafts 42 are embedded in the forked portion 16. The shafts 42 are made of metal. The shafts 42 extend downward from the forked portion 16. The shafts 42 are inclined from the upper side to the lower side and to the front side in the loading state (see Figure 1 ). The rotating body 12 is rotatably supported by the shaft 42.

[0077] The bearing 44 is cylindrical. The bearing 44 is made of synthetic resin. The bearing 44 has an elastic protrusion 48 (see Figure 4 ). The elastic protrusion 48 is caught by the inner surface of the rotating body 12. Thus, the bearing 44 is fixed to the inner side of the rotating body 12.

[0078] like Figure 7 As shown, the strength with which the pair of rotating bodies 12 pinches the treatment area can be adjusted by the angle at which the pair of rotating bodies 12 touches the treatment area. Figure 7(A) shows a case where the massage device 10 is moved forward. In this case, the strength with which the pair of rotating bodies 12 pinches the treatment area is stronger when the massage device 10 is in an upright state than when the massage device 10 is in a lying state. In this case, when the massage device 10 is in a lying state, the pair of rotating bodies 12 push the treatment area. When the massage device 10 is in a lying state, the extension portion 18 touches the treatment area to prevent the massage device 10 from lying too much. Thus, the treatment effect of the pair of rotating bodies 12 can be prevented from being excessively weakened.

[0079] Figure 7 (B) shows a case where the massage device 10 is moved backward. In this case, the strength of the pair of rotating bodies 12 to hold the treatment area is stronger when the massage device 10 is lying down than when the massage device 10 is standing up. In this case, when the massage device 10 is standing up, the pair of rotating bodies 12 push the treatment area to the left and right. When the massage device 10 is lying down, the extension part 18 touches the treatment area to prevent the massage device 10 from lying down too much. This can prevent the situation where it is difficult to achieve the treatment effect envisioned by the design of the pair of rotating bodies 12.

[0080] When the pair of rotating bodies 12 touch the skin, the angle of the rotating axis R relative to the skin, which becomes the boundary between pinching and pushing, is 90 degrees. Although the effect changes with the direction of travel of the massage device 10, it is assumed that Fig.19 When the horizontal plane H is the skin, when the rotating body 12 contacts the skin ( Fig.19 When the angle between the rotation axis R and the skin in the direction of travel (the front side in the case of forward movement, the rear side in the case of backward movement) is less than 90 degrees, the skin is pinched, and when it is greater than 90 degrees, the skin is stretched. However, since the skin is soft, the rotating body 12 sinks into the skin. Even if the rotating body 12 touches the skin at an angle of 90 degrees relative to the skin before sinking, the contact angle of the skin may change after sinking, resulting in a structure that is pinched beyond imagination. For example, even if the rotating body 12 touches the skin at an angle of 85 degrees relative to the skin before sinking, the skin is pinched when the rotating body 12 sinks into the skin and moves forward.

[0081] like Figure 1 As shown, the massage device 10 is arranged in the order of a pair of rotating bodies 12, a scraping part 13, and a gripping part 17 from front to back in the loading state. In the loading state, the scraping part 13 is located above the pair of rotating bodies 12. The scraping part 13 has a first face part 49, a second face part 51, and an edge part 52. The edge part 52 is formed by the outer edge of the first face part 49 and the outer edge of the second face part 51.

[0082] like Figure 1As shown, the first face portion 49 faces the front side. The first face portion 49 is continuous with the fork portion 16. The front side recess portion 70 is formed by the first face portion 49 and the fork portion 16. The second face portion 51 faces the rear side. The upper edge of the second face portion 51 is inclined from the upper side to the lower side toward the rear side when viewed from the left and right direction. The second face portion 51 is continuous with the front side connecting portion 32.

[0083] like Figure 1 As shown in FIG. 1 , when viewed from the left and right sides, the edge portion 52 is inclined from the upper side toward the lower side toward the rear side. In the placed state, the lower end of the edge portion 52 is located above the upper end of the rotating body 12. In the placed state, the upper end of the edge portion 52 is located above the upper end of the grip portion 17. In the placed state, the upper end of the edge portion 52 is located above the upper end of the front connecting portion 32.

[0084] like Figure 2 As shown, when viewed from above, the edge 52 of the scraping part 13 is in a gentle arc shape. When viewed from above, the left-right center of the edge 52 of the scraping part 13 is located in front of both ends in the left-right direction.

[0085] like Figure 1 As shown, the imaginary plane V along the edge portion 52 of the scraping portion 13 is inclined relative to the horizontal plane H. The imaginary plane V is an imaginary plane including the edge portion 52 of the scraping portion 13. The imaginary plane V is substantially parallel to the front surface of the front surface portion 27 and the rear surface of the rear surface portion 28. The imaginary plane V includes the outer peripheral edge when the first face portion 49 is observed from the front, or the outer peripheral edge when the second face portion 51 is observed from the rear.

[0086] The gripping portion 17 is disposed on the rear side of the imaginary plane V. In a side view of the massage device 10 in the left-right direction, the opening angle β1 between the axis 17S of the gripping portion 17 and the imaginary plane V is, for example, 70 degrees. The axis 17S of the gripping portion 17 is the center of the thickness direction of the gripping portion 17. The opening angle β1 may be set to be greater than 0 degrees and less than 180 degrees. Preferably, the opening angle β1 is within a range of greater than 30 degrees and less than 150 degrees. More preferably, the opening angle β1 is within a range of greater than 60 degrees and less than 120 degrees. In this case, force can be effectively applied to the treatment area.

[0087] The shaft 42 extends toward the front side (front) relative to the imaginary plane V. When viewed from the left and right direction, the shaft 42 extends obliquely relative to the imaginary plane V. The opening angle β2 between the rotation axis R projected on the XY plane and the imaginary plane V is greater than 90 degrees. The opening angle β2 is, for example, 135 degrees.

[0088] Figure 8The massage device 10 is viewed from the front side in a direction perpendicular to the imaginary plane V. The direction perpendicular to the imaginary plane V and from the front side to the rear side is referred to as the first direction. Observing the massage device 10 along the first direction is referred to as first direction observation. In the first direction observation, the left and right rotating bodies 12 are located outside the edge portion 52.

[0089] The edge portion 52 includes an upper edge portion 52U, a right edge portion 52R, and a left edge portion 52L. When viewed in the first direction, the upper edge portion 52U is curved. When viewed in the first direction, the left-right center portion of the upper edge portion 52U is located on the upper side than the left-right ends of the upper edge portion 52U. When viewed in the first direction, the right edge portion 52R and the left edge portion 52L are adjacent to the left and right rotating bodies 12. The right edge portion 52R and the left edge portion 52L are curved more gently than the upper edge portion 52U when viewed in the first direction. When viewed in the first direction, the up-down center portion of the right edge portion 52R is located on the right side than the upper end and the lower end of the right edge portion 52R. When viewed in the first direction, the up-down center portion of the left edge portion 52L is located on the left side than the upper end and the lower end of the left edge portion 52L. When viewed in the first direction, the right edge portion 52R and the right rotating body 12 form a right side concave portion 71. When viewed in the first direction, the left edge portion 52L and the left rotating body 12 form a left recessed portion 72 .

[0090] Fig. 9 The massage device 10 is shown as viewed from the rear side in a direction perpendicular to the imaginary plane V. The direction perpendicular to the imaginary plane V and from the rear side toward the front side is referred to as the second direction. Observing the massage device 10 along the second direction is referred to as observing in the second direction. In the second direction observation, the left and right rotating bodies 12 are located outside the edge portion 52. In the second direction observation, a portion of the left and right rotating bodies 12 is shielded by the gripping portion 17. In the second direction observation, the upper edge of the front connecting portion 32 is bent along the upper edge portion 52U.

[0091] Fig.10 Indicates the massage device 10 observed from the upper side in a direction parallel to the imaginary plane V. The direction parallel to the imaginary plane V and from the upper side to the lower side is called the third direction. Observing the massage device 10 along the third direction is called the third direction observation. In the third direction observation, a pair of rotation axes R intersects at the front side of the imaginary plane V. In the third direction observation, a right middle tapered portion 73 and a left middle tapered portion 74 are formed between the first face portion 49 and the bifurcated portion 16. In the third direction observation, the left-right dimension of the second face portion 51 decreases toward the gripping portion 17. In the third direction observation, the left and right edges of the second face portion 51 are inclined at the same slope as the left and right edges of the front connecting portion 32.

The protruding end surface 54 of the large protrusion 14 and the protruding end surface 55 of the small protrusion 15 are curved in an arc shape in the left-right direction.

[0105] like Figure 4 As shown, the massage device 10 includes a core member 23. The core member 23 integrally includes a head 56 and a shaft-like portion 21. The head 56 integrally includes a fork portion 16 and a scraping portion 13. The shaft-like portion 21 extends rearward from the head 56. The core member 23 uses the shaft 42 and the bolt 26 as embedded components, and integrally forms the fork portion 16, the scraping portion 13, and the shaft-like portion 21. The fork portion 16, the scraping portion 13, and the shaft-like portion 21 are formed of a synthetic resin such as ABS resin. The shaft-like portion 21 is inserted from the front side connecting portion 32 of the extension portion 18 to the rear side connecting portion 33. The rear surface of the head 56 is in a state of contacting the front surface of the front side connecting portion 32. The rear end portion of the shaft-like portion 21 is fixed to the rear side connecting portion 33 of the extension portion 18. Thus, the core member 23, the gripping portion 17, and the extension portion 18 are integrated. Since the strength of the main body 11 is improved by integrating the grip portion 17 and the extension portion 18 , it is easy to apply force when pressing the body with the large protrusion 14 and the small protrusion 15 .

[0106] Next, refer to Fig.19 The dimensions of the massage device 10 are described. An imaginary plane that passes through the rear end 17P of the gripping portion 17 and is tangent to the pair of rotating bodies 12 at the same time is called a first imaginary plane V1. The rear end 17P of the gripping portion 17 is the rearmost point in the gripping portion 17 when the massage device 10 is observed from the left and right directions. The opening angle β3 between the rotation axis R projected on the XY plane and the first imaginary plane V1 is, for example, 54 degrees. The opening angle β3 can be set within a range greater than 0 degrees and less than 85 degrees. Preferably, the opening angle β3 is within a range greater than 17.5 degrees and less than 65 degrees. More preferably, the opening angle β3 is within a range greater than 35 degrees and less than 55 degrees.

[0107] The point where the rotating body 12 is tangent to the first imaginary plane V1 is called the first imaginary point of contact P1. The length dimension from the first imaginary point of contact P1 to the rear end 17P of the gripping portion 17 when observing the massage device 10 from the left and right directions is called the first length dimension L1. The first length dimension L1 is a length dimension parallel to the first imaginary plane V1. The first length dimension L1 is, for example, 151 mm.

Preferably, the first length dimension L1 is within a range of 100 mm to 180 mm. More preferably, the first length dimension L1 is within a range of 140 mm to 160 mm.

[0108] The imaginary plane that is simultaneously tangent to the pair of rotating bodies 12 and the extension surface 29 of the extension portion 18 is referred to as the second imaginary plane V2. The opening angle β4 between the rotation axis R projected on the XY plane and the second imaginary plane V2 is, for example, 68 degrees.

[0109] The point where the rotating body 12 is tangent to the second imaginary plane V2 is called the second imaginary point of contact P2. The point where the extension 18 is tangent to the second imaginary plane V2 is called the extension point of contact 18P. The length dimension from the second imaginary point of contact P2 to the extension point of contact 18P when observing the massage device 10 from the left and right directions is called the second length dimension L2. The second length dimension L2 is a length dimension parallel to the second imaginary plane V2. The second length dimension L2 is, for example, 116 mm. The second length dimension L2 can be set in the range of 40 mm to 200 mm. Preferably, the second length dimension L2 is in the range of 85 mm to 160 mm. More preferably, the second length dimension L2 is in the range of 105 mm to 125 mm.

[0110] The front end of the extended portion 29 in the loading state is referred to as the extended portion front point 29P. The extended portion front point 29P is the frontmost point of the extended portion 29 when the massage device 10 is observed from the left and right directions. The extended portion front point 29P coincides with the front end of the large protrusion 14. The length dimension from the second imaginary tangent point P2 to the extended portion front point 29P when the massage device 10 is observed from the left and right directions is referred to as the third length dimension L3. The third length dimension L3 is a length dimension parallel to the second imaginary plane V2. The third length dimension L3 is, for example, 50 mm.

[0111] When the massage device 10 is observed from the left and right sides, the opening angle β5 between the rotation axis R and the horizontal plane H is, for example, 75 degrees. The opening angle β5 can be set within a range greater than 0 degrees and less than 110 degrees. Preferably, the opening angle β5 is within a range of greater than 27.5 degrees and less than 90 degrees. More preferably, the opening angle β5 is within a range of greater than 55 degrees and less than 80 degrees.

[0112] The point where the rotating body 12 is tangent to the horizontal plane H is called the third imaginary point of contact P3. The point where the large protrusion 14 is tangent to the horizontal plane H is called the lower point 14P of the protrusion. The length dimension from the third imaginary point of contact P3 to the lower point 14P of the protrusion when observing the massage device 10 from the left and right directions is called the fourth length dimension L4. The fourth length dimension L4 is a length dimension parallel to the horizontal plane H. The fourth length dimension L4 is, for example, 75 mm.

Preferably, the fourth length dimension L4 is in the range of more than 45 mm and less than 140 mm. More preferably, the fourth length dimension L4 is in the range of more than 65 mm and less than 85 mm.

[0113] With the above-mentioned dimensions, the massage device 10 can be tilted at an appropriate angle during the forward and backward movement of the massage device 10. With the above-mentioned dimensions, the user's hand holding the extension portion 18 or the grip portion 17 is unlikely to become an obstacle when the massage device 10 is tilted. With the above-mentioned dimensions, even in a relatively narrow treatment range such as a female forearm, the pair of rotating bodies 12 and the extension portion 18 or the large protrusion 14 can be touched at the same time.

[0114] Next, an example of using the massage device 10 is described. By using the massage device 10, the user can effectively warm up and cool down before exercise. Fig.11 and Fig.12 As shown, the massage device 10 is suitable for massaging the forearms, upper arms, thighs, etc.

[0115] Examples of using the massage device 10 include a method using the rotating body 12 and the protrusions 14 and 15 , a method using only the scraping part 13 , and a method using both the scraping part 13 and the rotating body 12 .

[0116] like Fig.11 and Fig.12 As shown in FIG. 1 , the method of using both the rotating body 12 and the protrusions 14 and 15 is suitable for massaging the forearm, upper arm, thigh, etc. The massage device 10 can be as follows Fig.11 As shown in (A), the thumb and index finger are attached to the front side of the grip portion 17 to grip the grip portion 17, or Fig.11 As shown in (B), the thumb and index finger are attached to the rear side of the grip portion 17 to grip the grip portion 17.

[0117] The method of using the rotating body 12 and the protrusions 14 and 15 is as follows Fig.12 (A) is a method for moving the massage device 10 linearly, as shown in Fig.12 (B) There are a method of moving the massage device 10 in an arc, a method of using only the rotating body 12, and a method of using only the protrusions 14 and 15.

[0118] like Fig.17 As shown, the method of moving the massage device 10 linearly is to make the pair of rotating bodies 12, the large protrusion 14 and the small protrusion 15 touch the treatment area at the same time, and move the massage device 10 parallel to the treatment area. In this state, the massage device 10 lies down, so the pair of rotating bodies 12 push the treatment area. The large protrusion 14 and the small protrusion 15 press the treatment area that has just been pushed. The pressing by the large protrusion 14 achieves an effect similar to thumb pressure. This method is suitable for warming up before exercise.

[0119] like Fig.18 As shown, the method of moving the massage device 10 in an arc is to move the massage device 10 forward in an arc from a state where only the pair of rotating bodies 12 are in contact with the body. Thus, the massage device 10 is transferred to a first state where only the pair of rotating bodies 12 are ejecting, a second state where only the pair of rotating bodies 12 are in contact with the large protrusions 14, and a third state where only the large protrusions 14 are in contact with the small protrusions 15.

[0120] In the first state, the massage device 10 stands upright, so the pair of rotating bodies 12 strongly pinches the treatment area. During the transition from the first state to the second state, the massage device 10 lies down, and the force of pinching the treatment area by the pair of rotating bodies 12 becomes weaker. In the second state, the treatment area is pushed by the pair of rotating bodies 12 and pressed by the large protrusion 14. In the third state, the treatment area is further pressed by the small protrusion 15. With this method, the treatment area is pushed after being strongly pinched by the pair of rotating bodies 12, and is pressed by the large protrusion 14 and the small protrusion 15 in sequence. This method is suitable for cooling down after exercise.

[0121] And it can also be Figure 7 (B) The massage device 10 is moved backward for use. In this case, when the pair of rotating bodies 12, the large protrusion 14, and the small protrusion 15 are moved straightly so as to simultaneously touch the treatment area, the treatment area pressed by the protrusions 14 and 15 for pressing the body can be lifted up by the pair of rotating bodies 12. Furthermore, after the large protrusion 14 and the small protrusion 15, or only the large protrusion 14, are pushed against the treatment area, the massage device 10 is placed in a lying state or in an upright state so that the pair of rotating bodies 12 touch the treatment area, thereby the treatment area pressed by the protrusions 14 and 15 for pressing the body can be lifted up or pushed out by the pair of rotating bodies 12.

[0122] The method using only the rotating bodies 12 is to move the massage device 10 forward and backward in a state where the pair of rotating bodies 12 touch the treatment area. At this time, the massage device 10 is sometimes laid down and sometimes stood up to adjust the angle at which the pair of rotating bodies 12 touch the treatment area. This method is suitable for massaging the calf or waist.

[0123] The method using only the protrusions 14 and 15 is to make the large protrusion 14 and the small protrusion 15 touch the treatment part vertically, and push the large protrusion 14 and the small protrusion 15 against the treatment part. This method is suitable for massaging the sole of the foot or the shoulder.

[0124] In the method using the scraping part 13, the gripping part 17 is gripped by attaching the thumb and index finger to the front side of the gripping part 17. In the method using only the scraping part 13, the upper edge 52U of the scraping part 13 is used. Specifically, the upper edge 52U is made to touch the treatment site, and the treatment site is sometimes rubbed and sometimes pressed by the upper edge 52U. In the case of gripping the gripping part 17 and using only the scraping part 13, it is easy to apply force to the scraping part 13 in a state where the scraping part 13 is pushed against the treatment site.

[0125] like Fig.13As shown, in the method using both the scraping part 13 and the rotating body 12, the edge 52 of the scraping part 13 and one rotating body 12 are brought into contact with the treatment site at the same time. Specifically, the right side concave part 71 is directed toward the treatment site so that the right edge 52R of the scraping part 13 and the rotating body 12 on the right are brought into contact with each other at the same time. Alternatively, the left side concave part 72 is directed toward the treatment site so that the left edge 52L of the scraping part 13 and the rotating body 12 on the left are brought into contact with each other at the same time. The force of pressing the edge 52 and the rotating body 12 toward the treatment site by holding the holding part 17 is easily applied evenly to both the edge 52 and the rotating body 12. The massage device 10 is moved forward and backward in the state where the edge 52 and the rotating body 12 are pushed and contacted. Thus, the treatment site can be massaged simultaneously by both the edge 52 of the scraping part 13 and the rotating body 12.

[0126] The following effects are achieved by the embodiment constructed as described above. The massage device 10 has a scraping part 13 and a holding part 17. The scraping part 13 has an edge part 52 and a first face part 49 and a second face part 51. The holding part 17 is provided on the second face part 51. The holding part 17 extends in a direction intersecting with the second face part 51. According to this structure, when only the scraping part 13 is used while holding the holding part 17, it is easy to apply force to the scraping part 13 when the scraping part 13 is pushed against the treatment area.

[0127] The massage device 10 has a shaft 42 and a rotating body 12. The shaft 42 extends in a direction intersecting the first surface 49 on the front side of the imaginary plane V along the edge portion 52. The rotating body 12 is rotatably supported on the shaft 42. When the massage device 10 is viewed from a direction perpendicular to the imaginary plane V, the rotating body 12 is located outside the edge portion 52. According to this structure, both the rotating body 12 and the scraping part 13 can touch the treatment area at the same time to massage, so that the body can be effectively massaged and relaxed.

[0128] The massage device 10 is arranged from front to back in the order of the rotating body 12, the scraping part 13 and the gripping part 17. According to this structure, it is easy to push both the rotating body 12 and the scraping part 13 against the treatment part at the same time, so the body can be massaged and relaxed effectively.

[0129] The scraping part 13 is arranged at the top and the rotating body 12 is arranged at the bottom with respect to the gripping part 17. According to this structure, when both the rotating body 12 and the scraping part 13 are pushed against the treatment part, it is easy to apply force to both the rotating body 12 and the scraping part 13, so that the body can be effectively kneaded and relaxed.

[0130] A pair of rotating bodies 12 are provided on the left and right. The scraping part 13 has a left edge part 52L and a right edge part 52R adjacent to the left and right rotating bodies 12. According to this structure, both the rotating body 12 and the scraping part 13 can touch the treatment part at the same time to massage the treatment part on either the left side or the right side of the massage device 10, so that the direction of the massage device 10 can be changed to effectively massage and relax various parts of the body.

[0131] The massage device 10 includes a main body 11, a shaft 42, a rotating body 12, and protrusions 14 and 15 for pressing the body. The shaft 42 extends downward from the main body 11. The rotating body 12 is rotatably supported on the shaft 42. The protrusions 14 and 15 for pressing the body protrude downward from the main body 11. The shaft 42 and the rotating body 12 are provided in a pair. The pair of rotating bodies 12 and the protrusions 14 and 15 can contact the treatment site at the same time. In the side view observed from the left and right directions, the angle β3 formed by the horizontal plane H tangent to the three points of the pair of rotating bodies 12 and the large protrusion 14 and the rotation axis R of the rotating body 12 is greater than 0 degrees and less than 110 degrees. According to this structure, the treatment site that is sometimes pinched and sometimes pushed by the pair of rotating bodies 12 can be pressed by the protrusions 14 and 15 for pressing the body. Moreover, the treatment site pressed by the protrusions 14 and 15 for pressing the body can be sometimes pinched and sometimes pushed by the pair of rotating bodies 12. Therefore, the body can be kneaded and relaxed effectively.

[0132] The massage tool 10 is provided with two protrusions 14 and 15. According to this structure, the treatment area can be pressed by the two protrusions 14 and 15, so that the body can be massaged and relaxed effectively.

[0133] The two protrusions 14 and 15 are different in size. According to this structure, the pressing method of the treatment area can be changed by the two protrusions 14 and 15 of different sizes, so the body can be kneaded and relaxed effectively.

[0134] The two protrusions 14 and 15 are provided at the rear of the pair of rotating bodies 12. The two protrusions 14 and 15 are arranged in order from the larger one to the front to the rear. According to this structure, the treatment by the pair of rotating bodies 12 and the treatment by the two protrusions 14 and 15 can be performed continuously.

[0135] The main body 11 has a grip 17 and an extension 18, and the projections 14 and 15 are provided on the extension 18. The grip 17 is gripped by a user. The extension 18 extends downward from the grip 17. According to this structure, the projections 14 and 15 can be arranged at a position where they do not interfere with the grip 17 when the user grips it.

[0136] <Other Examples>

[0137] The present invention is not limited to the embodiments illustrated in the above description and drawings, and for example, the following embodiments are also included in the technical scope of the present invention.

[0138] (1) In the above embodiment, the massage device 10 includes a pair of rotating bodies 12. However, the present invention is not limited thereto, and the massage device may include only one rotating body, or may include three or more rotating bodies.

[0139] (2) In the above embodiment, the massage device 10 has the protrusions 14 and 15 for pressing the body. However, the present invention is not limited to this, and the massage device may not have the protrusions for pressing the body.

[0140] (3) The above embodiment describes the use of the massage device 10. The massage device 10 is not limited thereto, and can be used for various purposes. For example, the massage device 10 can also be used for beauty purposes.

[0141] (4) In the above embodiment, the gripping portion 17 is formed in a shape long in the front-rear direction. However, the present invention is not limited thereto, and the gripping portion may be a flat shape or a block shape that is wide in the up-down direction or the left-right direction.

[0142] (5) In the above embodiment, the main body 11 has the extension 18. However, the main body may not have the extension. In addition, only the front connecting portion may be left, and the scraping part and the gripping part may be connected by the front connecting portion.

[0143] (6) In the above embodiment, the scraping part may be provided with a third face part in addition to the first face part and the second face part. In this case, the scraping part is triangular in shape and has multiple edge parts, but by providing the holding part in a manner of crossing with any face as in the embodiment, it is possible to achieve an effect of easy force application when the scraping part is pushed against the treatment part. The same effect can be achieved even when the face part is further increased.

[0144] (7) Regarding the shape of the rotating body in the above-mentioned embodiment, the above-mentioned "substantially spherical" includes a sphere, and a shape such as a rotating ellipsoid or a teardrop shape that is deformed to the extent that it is generally considered to be spherical. In addition, the rotating body may have a surface composed of smooth curved surfaces, or may be a polyhedron having a surface composed of, for example, a plurality of triangles or quadrilaterals. In the case where the rotating body is a polyhedron, compared with a rotating body having a surface composed of smooth curved surfaces, it is possible to suppress the surface of the rotating body from sliding relative to the skin, and it is expected to achieve a more excellent cosmetic effect.

[0145] (8) The shape of the main body of the above-mentioned embodiment is not limited to a long strip, and may be roughly spherical. In this case, the gripping portion refers to the entire portion that can be gripped, and when the rotating body and the protrusion are grounded at three points in a side view, at least a part of the gripping portion is located closer to the ground than the rotation axis angle (imaginary line) of the rotating body.

[0146] (9) When the massage device is viewed from a direction perpendicular to the surface portion of the first face portion or the second face portion on the side opposite to the axis, when the rotating body is located outside the edge portion, it is easy to push both the rotating body and the scraping portion against the treatment area at the same time, thereby effectively massaging and relaxing the body.

[0147] (10) For example, the first face portion and the second face portion may be formed with corrugated concavities and convexities as a whole, or the first face portion and the second face portion may be curved surfaces. In this case, a surface including any three points on the edge portion may be defined as the imaginary surface V. Even when the gripping portion and the shaft extend in a direction intersecting the imaginary surface defined in this way, the same effects as those of the above-described embodiment can be achieved.

[0148] (11) In the above embodiment, two protrusions for pressing the body are provided. However, the present invention is not limited thereto, and only one protrusion for pressing the body may be provided, or three or more protrusions may be provided.

[0149] (12) In the above embodiment, the protrusion for pressing the body includes the large protrusion 14 and the small protrusion 15. However, the present invention is not limited to this, and a plurality of protrusions of the same size may be provided as the protrusion for pressing the body.

[0150] (13) In the above embodiment, the main body 11 has the extension 18. This is not limiting, and the main body may not have the extension. In this case, a part of the grip may be formed into a shape protruding downward, and a protrusion may be provided on its lower surface.

[0151] (14) In the above embodiment, the extension portion 18 includes the front surface portion 27, the rear surface portion 28, and the extension surface portion 29. The extension portion is not limited to this, and may only include a portion extending downward from the grip portion. The portion may have an extension length that allows the rotating body to easily touch the treatment site at an appropriate angle.

[0152] (15) In the above embodiment, the front and rear surfaces of the large protrusion 14 are inclined toward each other toward the protruding end surface 54 of the large protrusion 14. However, the present invention is not limited thereto, and the protrusion may protrude from the base to the protruding end surface with the same thickness.

[0153] (16) In the above embodiment, numerical values ​​related to the size of the massage device 10 are illustrated. Without being limited to this, the structure of the present invention can also be applied to small massage devices. In this case, the diameter of the rotating body is about 15 mm, the length dimension of the gripping portion is 110 mm, the second length dimension L2 is 20 mm, and the fourth length dimension L4 is 15 mm. The angles can be the same as those in the above embodiment. The numerical values ​​of the second length dimension L2 and the fourth length dimension L4 are not limited to the ranges described in the specification, and can be appropriately changed according to the diameter of the rotating body and the length of the gripping portion.

[0154] (17) The shape of the main body of the above-mentioned embodiment is not limited to a long strip, and may be roughly spherical. In this case, the gripping portion refers to the entire portion that can be gripped, and when the rotating body and the protrusion are grounded at three points in a side view, at least a part of the gripping portion is located closer to the ground than the rotation axis angle (imaginary line) of the rotating body.
