Description

[Technical field]

[0001] The present invention relates to a massage belt. [Background technology]

[0002] Patent Document 1 discloses a conventional massage belt. This massage belt is detachably attached to the vibration part of a massage tool. This massage belt includes a belt body, an attachment part, and a handle. The belt body is flat and belt-shaped. One end of the belt body is connected to the attachment part. The attachment part is attached to the vibration part of the massage tool. The handle is connected to the other end of the belt body. This massage belt is used by a user who holds the massage tool in one hand and the handle with the other hand, who brings the belt body into a taut state by closely contacting it with the part of the body that the user wants to massage, such as the waist, back, or legs, and drives the vibration part of the massage tool. This causes the massage belt to vibrate in the direction in which it is extended, allowing the user to massage the part of the body that the user desires. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Design Registration No. 1745983 Summary of the Invention [Problem to be solved by the invention]

[0004] The massage belt of Patent Document 1 is used by a user holding a handle at the other end of the belt body. Since the handle does not vibrate, the vibration of the vibration part of the massage tool is transmitted from one end of the belt body connected to the attachment part attached to the vibration part to the other end of the belt body connected to the handle. The vibration gradually weakens from one end of the belt body to the other end while transmitting through the belt body. For this reason, this massage belt may have a different massage effect in parts where the belt body is applied. In addition, since this massage belt is used by a user holding the massage tool with one hand and the handle with the other hand, if the strength of one hand is loosened and the belt body is no longer in a taut state, the vibration may not be transmitted well to the belt body, and the massage effect may not be obtained.

[0005] The present invention has been made in consideration of the above-mentioned conventional circumstances, and an object to be achieved is to provide a massage belt that can provide a good massage. [Means for solving the problem]

[0006] The massage belt of the present invention is A massage belt that can be detachably attached to a vibration part of a massage tool, In a state of use, a belt body that is hung in a ring shape, a mounting portion for mounting the belt body to the vibration portion; It is equipped with:

[0007] In this massage belt, the part to be massaged is placed inside the belt body that is hung in a ring shape. The user holds the massage tool in one hand, places the belt body against the part to be massaged, and moves the massage tool in a direction away from the part to be massaged, bringing the belt body into close contact with the part to be massaged and into a taut state. In this state, the user can massage by driving the vibration unit of the massage tool. In this way, this massage belt makes it easy to bring the belt body into close contact with the part to be massaged and into a taut state, and the ring-shaped belt body can vibrate the entire belt body approximately evenly.

[0008] Therefore, the massage belt of the present invention can provide a good massage. [Brief description of the drawings]

[Figure 14] 13(A) and 13(B) are plan views showing another embodiment of the belt body. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] A preferred embodiment of the present invention will now be described.

[0011] The attachment portion of the massage belt of the present invention can connect both ends of the belt body. In this case, the massage belt can be connected to the attachment portion in a ring shape.

[0012] At least one of both ends of the belt body of the massage belt of the present invention can be detachably connected to the attachment part. In this case, the length of the ring-shaped portion of the massage belt can be easily adjusted by utilizing the detachable end of the belt body.

[0013] The attachment part of the massage belt of the present invention may have an attachment part main body extending in the vibration direction of the vibration part when attached to the vibration part of the massage tool, and a belt connecting part connecting both ends of the belt main body side by side in the vibration direction. In this case, the massage belt can transmit the vibration of the vibration part of the massage tool to both ends of the belt main body in a well-balanced manner.

[0014] The attachment portion of the massage belt of the present invention has a belt connecting portion that connects the ends of the belt body, and the belt connecting portion has a through hole, and when the end of the belt body is passed through the through hole and folded back and overlapped, the overlapped portion of the belt body can be detachably joined by a hook-and-loop fastener. In this case, the massage belt can easily change the degree of overlap of the ends of the belt body, and therefore the length of the ring-shaped portion can be easily adjusted.

[0015] The massage belt of the present invention may include a handle that is connected to one end of the belt body detached from the attachment part. In this case, the massage belt can be used by selecting either a method in which the handle is not connected to the belt body and the belt body is hung in a ring shape, or a method in which the handle is connected to one end of the belt body.

[0016] The vibration section to which the massage belt of the present invention is detachably attached extends in the vibration direction, has an open tip, and forms a recess with a circular inner circumference in a cross-sectional shape perpendicular to the vibration direction, and may include a female threaded section provided on the inner surface at the back of the recess, and a non-female threaded section provided on the opening side of the recess further from the female threaded section, with no threads cut on the inner surface, and with an inner diameter larger than the valley diameter of the female threaded section. The attachment part of the massage belt part of the present invention has an attachment part main body with a circular outer circumference in a cross section perpendicular to the vibration direction when inserted into the recess and attached to the vibration part, and the attachment part main body is provided with a male thread part on the outer peripheral surface of the tip part, which is screwed into the female thread part, and a non-male thread part provided behind the male thread part, which is not threaded on the outer peripheral surface, and whose outer diameter is slightly larger than the outer diameter of the male thread part and slightly smaller than the inner diameter of the non-female thread part, and the axial length of the male thread part is shorter than the axial length of the non-female thread part, and the axial length of the male thread part and the non-female thread part combined can be longer than the axial length of the non-female thread part. In this case, when the attachment part main body of the massage belt is inserted into the recess of the vibration part, the outer diameter of the male thread part is slightly smaller than the inner diameter of the non-female thread part and is almost the same, so that the positioning can be easily performed at the opening of the recess by the outer peripheral front end of the male thread part and the inner peripheral surface of the non-female thread part. In addition, the non-male threaded portion of the attachment body is inserted into the non-female threaded portion of the vibration part before the male threaded portion of the attachment body reaches the female threaded portion of the vibration part. At this time, since the outer diameter of the non-male threaded portion is slightly smaller than the inner diameter of the non-female threaded portion, the outer peripheral surface of the non-male threaded portion moves along the inner peripheral surface of the non-female threaded portion. Therefore, by simply inserting the attachment part into the recess of the vibration part, the male threaded portion of the attachment body can be moved to a position where it can be screwed into the female threaded portion of the vibration part. In this way, the male threaded portion of the attachment body can be easily screwed into the female threaded portion of the vibration part without visually checking the position of the female threaded portion of the vibration part.

[0017] The massage belt of the present invention may include an attachment having a convex portion that can be detachably attached to the belt body. In this case, the massage belt can obtain a finger pressure effect by using the attachment so that the convex portion of the attachment attached to the belt body comes into contact with the part to be massaged.

[0018] Next, a first embodiment of the massage belt of the present invention will be described with reference to the drawings.

[0019] <Example 1> The massage belt 1 of the first embodiment is detachably attached to the vibration part 20 of the massage tool 2, as shown in Figs. 1 to 7. The massage tool 2 includes a main body part 200 and a handle part 210, as shown in Figs. 1 and 4. The main body part 200 is substantially cylindrical. The handle part 210 is also substantially cylindrical. The outer diameter of the handle part 210 is smaller than the outer diameter of the main body part 200. One end of the handle part 210 is continuous with the outer peripheral surface of the main body part 200. The other end of the handle part 210 is closed. The central axis of the main body part 200 and the central axis of the handle part 210 are perpendicular to each other.

[0020] As shown in Figs. 4 to 6, the main body 200 has a vibration unit 20 arranged at one end in the central axis direction of the main body 200. The main body 200 incorporates an electric motor and a control unit (not shown). The handle 210 incorporates a rechargeable battery (not shown). The vibration unit 20 vibrates when driven by the electric motor. The control unit controls the drive of the electric motor in response to the operation of a push button 201 (described later). The rechargeable battery supplies power to the electric motor. The rechargeable battery can be charged from the outside via a charging cable (not shown).

[0021] 1, the main body 200 has a push button 201, a charging display unit 202, and a level display unit 203. The push button 201, the charging display unit 202, and the level display unit 203 are provided on an end face that closes the other end in the central axis direction of the main body 200. The push button 201 is used for turning the power on and off, and for switching the vibration frequency of the vibration unit 20 in stages. The charging display unit 202 displays the charge level of the rechargeable battery. The level display unit 203 displays the level of the vibration frequency of the vibration unit 20.

[0022] As shown in FIG. 4, the vibration part 20 is substantially cylindrical with one end open. The outer diameter R1 of the vibration part 20 is 22 mm. The outer diameter of the main body part 200 is about three times the outer diameter of the vibration part 20. The central axis of the vibration part 20 extends on the central axis of the main body part 200. The vibration part 20 vibrates in the direction of the central axis. In other words, the central axis of the vibration part 20 extends in the vibration direction of the vibration part 20. The vibration part 20 extends in the vibration direction and has an open tip. The vibration part 20 forms a recess 20A whose inner circumference is circular in a cross-sectional shape perpendicular to the vibration direction.

[0023] As shown in Figs. 4 to 6, the vibration section 20 has a female thread section 21 and a non-female thread section 23. The female thread section 21 is provided on the inner peripheral surface at the back side of the recess 20A. The non-female thread section 23 is provided continuous with the female thread section 21 on the opening side of the recess 20A relative to the female thread section 21. The non-female thread section 23 is a portion where no threads are cut. The non-female thread section 23 has an inner diameter slightly larger than the root diameter of the female thread section 21. The inner diameter R2 of the non-female thread section 23 is 19.10 mm. The axial length L1 of the non-female thread section 23 is 25 mm. The axial length L2 of the female thread section 21 is 15 mm.

[0024] As shown in Figs. 1, 2, 7, 8 and 10, the massage belt 1 includes a belt body 10, an attachment portion 100, and a handle 300. The belt body 10 is flat and belt-like. The width of the belt body is about 60 mm. The belt body 10 has a female hook-and-loop fastener 11 over the entirety of one side. The belt body 10 has a male hook-and-loop fastener 12 sewn onto the female hook-and-loop fastener 11 on one side of both ends of the belt body 10. Each male hook-and-loop fastener 12 is substantially rectangular with one side having the same length as the width direction of the belt body 10. Each male hook-and-loop fastener 12 is sewn onto the belt body 10 with one side aligned with each of the two end edges of the belt body 10, overlapping the belt body 10 so as not to protrude from the belt body 10.

[0025] As shown in Figures 1 to 7, the mounting part 100 has a mounting part main body 110 and a belt connecting part 130. As shown in Figures 4 to 6, the mounting part main body 110 is cylindrical. The mounting part main body 110 is integrated with the belt connecting part 130 by a screw S. The mounting part main body 110 is rotatable around the central axis of the mounting part main body 110 with respect to the belt connecting part 130.

[0026] The mounting body 110 has a male threaded portion 111, a non-male threaded portion 113, and an insertion portion 115. The male threaded portion 111 is provided on the outer circumferential surface of the tip of the mounting body 110. The male threaded portion 111 can be screwed into a female threaded portion 21 provided in the vibration portion 20. In a state in which the male threaded portion 111 of the mounting body 110 is screwed into the female threaded portion 21 of the vibration portion 20, the central axis of the mounting body 110 extends on the central axis of the vibration portion 20. In other words, in a state in which the mounting body 100 is attached to the vibration portion 20, the mounting body 110 extends in the vibration direction of the vibration portion 20.

[0027] The axial length L3 of the male threaded portion 111 of the mounting portion main body 110 is 14 mm. The axial length L3 of the male threaded portion 111 is shorter than the axial length L1 of the non-female threaded portion 23. The non-male threaded portion 113 is provided rearward (toward the belt connecting portion 130) of the male threaded portion 111 and continuous with the male threaded portion 111. The non-male threaded portion 113 is an unthreaded portion. The axial length L4 of the non-male threaded portion 113 is 22 mm. The combined axial length (L3+L4) of the male threaded portion 111 and the non-male threaded portion 113 is longer than the axial length L1 of the non-female threaded portion 23.

[0028] The outer diameter R3 of the non-male threaded portion 113 is 18.80 mm. The outer diameter R3 of the non-male threaded portion 113 is slightly larger than the outer diameter of the male threaded portion 111. The outer diameter R3 of the non-male threaded portion 113 is slightly (0.30 mm) smaller than the inner diameter R2 of the non-female threaded portion 23. The inner diameter of the male threaded portion 111 and the inner diameter of the non-male threaded portion 113 are equal. The inner diameters of the male threaded portion 111 and the non-male threaded portion 113 are slightly larger than the outer diameter of the washer W. When the attachment portion main body 110 and the belt connecting portion 130 are integrated, the washer W is sandwiched between the head of the screw S and the tip surface of a second shaft portion 131B of the belt connecting portion 130, which will be described later.

[0029] The insertion portion 115 is provided rearward of the non-male threaded portion 113 and continuous with the non-male threaded portion 113. The outer diameter of the insertion portion 115 is larger than the outer diameter R3 of the non-male threaded portion. An outer step portion 114A is provided on the outer peripheral surface of the boundary between the non-male threaded portion 113 and the insertion portion 115. The male threaded portion 111 of the attachment portion main body 110 can be screwed into the female threaded portion 21 of the vibration portion 20 until the outer step portion 114A contacts the open end face of the vibration portion 20.

[0030] The inner diameter of the insertion portion 115 is slightly larger than the outer diameter of the second shaft portion 131B of the belt connecting portion 130, which will be described later. The inner diameter of the insertion portion 115 is smaller than the inner diameter of the non-male thread portion 113. An inner step portion 114B is provided on the inner peripheral surface of the boundary portion between the non-male thread portion 113 and the insertion portion 115. The attachment portion main body 110 is integrated with the belt connecting portion 130 by inserting the second shaft portion 131B of the belt connecting portion 130, which will be described later, into the insertion portion 115 and screwing a washer W into the tip surface of the second shaft portion 131B protruding into the cavity of the non-male thread portion 113 of the attachment portion main body 110 with a screw S. The attachment portion main body 110 is rotatable around the second shaft portion 131B of the belt connecting portion 130. When the attachment portion 100 and the belt connecting portion 130 move relatively apart in the direction of the central axis of the second shaft portion 131B, the inner step portion 114B comes into contact with the washer W, thereby preventing separation.

[0031] As shown in Figs. 2 to 6, the belt connecting part 130 has a shaft part 131 and a belt connecting part main body 133. As shown in Figs. 4 to 6, the shaft part 131 has a first shaft part 131A and a second shaft part 131B. The first shaft part 131A is disk-shaped. The second shaft part 131B is cylindrical and extends linearly from the center of one end face of the first shaft part 131A. The central axis of the first shaft part 131A and the central axis of the second shaft part 131B extend on the same straight line. The first shaft part 131A and the second shaft part 131B have a pilot hole 131H formed from the tip face of the second shaft part 131B toward the first shaft part 131A in order to screw a screw S onto the central axis of the shaft part 131. The central axis of the shaft part 131 of the belt connecting part 130 and the central axis of the attachment part main body 110 extend on the same straight line.

[0032] The belt connecting part body 133 is flat as shown in Figs. 1 and 2. As shown in Fig. 3, the belt connecting part body 133 is substantially hexagonal in front view with the first side 133A to the sixth side 133F when one of the front and back sides of the belt connecting part body 133 is arranged to face a vertical plane facing the front. The first side 133A extends substantially linearly in the longitudinal direction of the belt connecting part body 133. The second side 133B and the third side 133C extend substantially linearly parallel to the lateral direction of the belt connecting part body 133. The second side 133B and the third side 133C have the same length. One end of the second side 133B is continuous with one end of the first side 133A, and one end of the third side 133C is continuous with the other end of the first side 133A. The portion where first side portion 133A and second side portion 133B are continuous, and the portion where first side portion 133A and third side portion 133C are continuous are curved to bulge outward. An interior angle formed by an extension line of a linearly extending portion of first side portion 133A intersecting with an extension line of a linearly extending portion of second side portion 133B is 90 degrees. An interior angle formed by an extension line of a linearly extending portion of first side portion 133A intersecting with an extension line of a linearly extending portion of third side portion 133C is 90 degrees.

[0033] One end of the fourth side 133D extends substantially linearly from the other end of the second side 133B. One end of the fifth side 133E extends linearly from the other end of the third side 133C. The fourth side 133D and the fifth side 133E have the same length. The portion where the second side 133B and the fourth side 133D are continuous, and the portion where the third side 133C and the fifth side 133E are continuous are curved so as to bulge outward. The interior angle formed by the intersection of the extension line of the linearly extending portion of the second side 133B and the extension line of the linearly extending portion of the fourth side 133D is about 105°. The interior angle formed by the intersection of the extension line of the linearly extending portion of the third side 133C and the extension line of the linearly extending portion of the fifth side 133E is about 105°.

[0034] Both ends of the sixth side portion 133F extend linearly and are continuous with the other end of the fourth side portion 133D and the other end of the fifth side portion 133E. The sixth side portion 133F is continuous with the other end face of the first shaft portion 131A. The length of the sixth side portion 133F is the same as the diameter of the first shaft portion 131A. In this way, the belt connecting portion main body 133 is continuous with the other end face of the first shaft portion 131A and is formed integrally with the shaft portion 131.

[0035] The belt connecting portion main body 133 is formed with a first through hole 135 and a second through hole 137 in the shape of a slit extending in the longitudinal direction. The first through hole 135 and the second through hole 137 extend in parallel. Each through hole 135, 137 extends in parallel to the first side portion 133A. Each through hole 135, 137 extends in a direction perpendicular to the central axis of the attachment portion main body 110. That is, each through hole 135, 137 is arranged side by side in the vibration direction. The length of each through hole 135, 137 is longer than the width of the belt main body 10 as shown in Figs. 4 to 6. The width of each through hole 135, 137 is more than twice the thickness of the belt main body 10.

[0036] The thickness of the belt connecting part main body 133 is about 1 / 3 of the outer diameter of the first shaft part 131A, as shown in FIG. 2. The belt connecting part main body 133 extends in a direction perpendicular to the other end face of the first shaft part 131A from the other end face of the first shaft part 131A to the part where the first through hole 135 is formed in a plan view. The belt connecting part main body 133 extends in a direction slightly inclined with respect to the direction perpendicular to the other end face of the first shaft part 131A from the part where the first through hole 135 is formed to the tip part constituting the first side part 133A in a plan view. This is because, when both ends of the belt main body 10 are connected to the belt connecting part main body 133, even if both ends of the belt main body 10 are passed through the first through hole 135, the both ends are unlikely to bend, and the vibration of the vibration part 20 is well propagated to both ends of the belt main body 10.

[0037] As shown in Figs. 7 to 9, the handle 300 has a handle body 310 and a belt connecting part 330. The belt connecting part 330 is flat. As shown in Fig. 9, the belt connecting part 330 has a substantially vertically elongated rectangular shape having a first side 330A to a fourth side 330D when viewed from the front in a state where one of the front and back surfaces of the belt connecting part 330 is arranged to face a vertical plane facing the front. The first side 330A extends substantially linearly in the longitudinal direction of the belt connecting part 330. The second side 330B and the third side 330C extend substantially linearly parallel to the lateral direction of the belt connecting part 330. The second side 330B and the third side 330C have the same length. One end of the second side 330B is continuous with one end of the first side 330A, and one end of the third side 330C is continuous with the other end of the first side 330A. The portion where the first side portion 330A and the second side portion 330B are continuous, and the portion where the first side portion 330A and the third side portion 330C are continuous are curved so as to bulge outward. The interior angle formed by the intersection of the extension line of the linearly extending portion of the first side portion 330A and the extension line of the linearly extending portion of the second side portion 330B is 90 degrees. The interior angle formed by the intersection of the extension line of the linearly extending portion of the first side portion 330A and the extension line of the linearly extending portion of the third side portion 330C is 90 degrees. Both ends of the fourth side portion 330D are continuous with the other end of the second side portion 330B and the other end of the third side portion 330C. The fourth side portion 330D is joined to the outer surface of the center portion of the connection portion 313 of the handle body 310 and is curved.

[0038] The belt connecting portion 330 is formed with a slit-shaped through hole 331 extending in the longitudinal direction. The through hole 331 extends parallel to the first side portion 330A. The length of the through hole 331 is longer than the width of the belt main body 10. The width of the through hole 331 is three times or more the thickness of the belt main body 10.

[0039] The handle body 310 has a grip part 311 and a connection part 313. The grip part 311 has a generally rectangular prism shape extending linearly. The central axis of the grip part 311 extends parallel to the through hole 331 of the belt connecting part 330. The surface of the grip part 311 on the belt connecting part 330 side has five protrusions 315 arranged in a wavy pattern in the direction along the central axis. The apexes of the protrusions 315 are spaced approximately the same apart. The height of the protrusions 315 at both ends is lower than the height of the three protrusions 315 between them.

[0040] The connecting part 313 is generally rectangular prism-shaped, extends in a generally arc-like curve, and is continuous with both ends of the grip part 311. The handle 300 has a belt connecting part 330 integrally formed on the outer surface of the center of the connecting part 313 of the handle body 310 (the outer surface opposite to the grip part 311).

[0041] There are two ways to use this massage belt 1. That is, one is to use the handle 300 by hanging the belt body 10 in a ring shape without connecting the handle 300 to the belt body 10, and the other is to use the handle 300 by connecting it to the other end of the belt body 10.

[0042] When the belt body 10 is used by hanging it in a ring shape, it is assembled as described below. First, one end of the belt body 10 is connected to the belt connecting part 130 of the attachment part 100. In detail, as shown in FIG. 2, one end of the belt body 10 is passed through the first through hole 135 and the second through hole 137 in that order. At this time, one end of the belt body 10 is passed through each of the through holes 135 and 137 so that one side on which the female hook-and-loop fastener 11 is provided faces outward when the belt body 10 is hung in a ring shape. The one end of the belt body 10 folded back through the second through hole 137 has a male hook-and-loop fastener 12 sewn thereon, and when it is superimposed on one side of the belt body 10 extending from the first through hole 135 on which the female hook-and-loop fastener 11 is provided, the one end of the belt body 10 can be detachably joined to any part of the belt body 10.

[0043] Next, the attachment part 100 is attached to the vibration part 20 of the massage tool 2. More specifically, as shown in FIG. 5, the insertion part 115 of the attachment part body 110 is pinched and the male thread part 111 and the non-male thread part 113 are inserted into the recess 20A of the vibration part 20. At this time, since the outer diameter of the male thread part 111 is slightly smaller than the inner diameter R2 of the non-female thread part 23 and there is almost no difference, positioning can be easily performed at the opening of the recess 20A by the outer circumferential front end part of the male thread part 111 and the inner circumferential surface of the non-female thread part 23. Also, before the male thread part 111 of the attachment part body 110 reaches the female thread part 21 of the vibration part 20, the non-male thread part 113 of the attachment part body 110 is inserted into the non-female thread part 23 of the vibration part 20. At this time, since the outer diameter R3 of the non-male threaded portion 113 is slightly smaller than the inner diameter R2 of the non-female threaded portion 23, the outer peripheral surface of the non-male threaded portion 113 moves along the inner peripheral surface of the non-female threaded portion 23. Therefore, the male threaded portion 111 of the attachment portion main body 110 can move to a position where it can be screwed into the female threaded portion 21 of the vibrating portion 20.

[0044] After the male thread portion 111 of the attachment body 110 reaches the female thread portion 21 of the vibration part 20, the attachment body 110 is rotated clockwise while pinching the insertion part 115 of the attachment body 110. Then, as shown in Fig. 6, the male thread portion 111 of the attachment body 110 is screwed into the female thread portion 21 of the vibration part 20 until the outer step portion 114A provided on the outer peripheral surface of the boundary between the non-male thread portion 113 and the insertion part 115 contacts the open end face of the vibration part 20. The attachment body 110 can no longer be rotated, and the attachment of the vibration part 20 of the massage tool 2 to the attachment part 100 is completed.

[0045] Next, the other end of the belt body 10 is connected to the belt connecting part 130 of the attachment part 100. More specifically, as shown in FIG. 2, the other end of the belt body 10 is passed through the first through hole 135. At this time, the other end of the belt body 10 is passed through the first through hole 135 so that the belt body 10 hung in a ring shape is not twisted. The other end of the belt body 10 folded back through the first through hole 135 has a male hook-and-loop fastener 12 sewn thereon, and when it is superimposed on one side of the belt body 10 extending from the first through hole 135 on which the female hook-and-loop fastener 11 is provided, it can be detachably joined to any part of the belt body 10. Depending on the physique of the user and the part to be massaged, the folded back positions of both ends of the belt body 10 are changed to adjust the length of the ring-shaped part. This completes the assembly when the belt body 10 is hung in a ring shape. The order of assembly does not have to be the order described.

[0046] A method of using this massage belt 1 in a ring shape will be described below. As shown in Fig. 10 to Fig. 12, the user holds the handle 210 of the massage tool 2 with one hand while placing the belt body 10 against the waist, back, sole of the foot, etc. that is to be massaged, and moves the massage tool 2 in a direction away from the waist, back, sole of the foot, etc., so that the belt body 10 is in close contact with the waist, back, sole of the foot, etc. and in a taut state. In this state, the user presses the push button 201 of the massage tool 2 to turn on the power of the massage tool 2 and can perform a massage at a desired vibration level.

[0047] When the handle 300 is connected to the other end of the belt body 10 for use, it is assembled as described below. As in the case where the belt body 10 is used by hanging it around in a ring shape as described above, one end of the belt body 10 is connected to the belt connecting part 130 of the attachment part 100, and the attachment part 100 is attached to the vibration part 20 of the massage tool 2.

[0048] Next, the other end of the belt body 10 is connected to the handle 300. More specifically, as shown in Figs. 7 and 8, the other end of the belt body 10 is passed through a through hole 331 formed in the belt connection part 330 of the handle 300. The other end of the belt body 10 folded back through the through hole 331 has a male hook-and-loop fastener 12 sewn thereon, and when it is placed on one side of the belt body 10 extending from the through hole 331 on which the female hook-and-loop fastener 11 is provided, it can be detachably joined to any part of the belt body 10. Depending on the physique of the user and the part to be massaged, the folding positions of both ends of the belt body 10 are changed to adjust the length. This completes the assembly when the handle 300 is connected to the other end of the belt body 10 for use.

[0049] A method of connecting the handle 300 to the other end of the massage belt 1 and using it will be described below. The user places the belt body 10 against the shoulders, buttocks, calves, etc. that the user wishes to massage, and holds the grip part 210 of the massage tool 2 with one hand and the grip part 311 of the handle 300 with the other hand to bring the belt body 10 into close contact with the shoulders, buttocks, calves, etc., creating a taut state. In this state, the user presses the push button 201 of the massage tool 2 to turn on the power of the massage tool 2, and can perform a massage at a desired vibration level.

[0050] As described above, the massage belt 1 of the first embodiment is detachably attached to the vibration part 20 of the massage tool 2. This massage belt 1 includes a belt body 10 that is hung in a ring shape in a usage state, and an attachment part 100 that attaches the belt body 10 to the vibration part 20.

[0051] In this massage belt 1, the part to be massaged is placed inside the belt body 10 that is hung in a ring shape. The user holds the massage tool 2 in one hand, places the belt body 10 against the part to be massaged, and moves the massage tool 2 in a direction away from the part to be massaged, thereby bringing the belt body 10 into close contact with the part to be massaged and into a taut state. In this state, the user can perform a massage by driving the vibration unit 20 of the massage tool 2. In this way, this massage belt 1 makes it easy to bring the belt body 10 into close contact with the part to be massaged and into a taut state, and the ring-shaped belt body 10 can vibrate the entire belt body 10 approximately evenly.

[0052] Therefore, the massage belt 1 of the first embodiment can provide a good massage.

[0053] The attachment portion 100 of the massage belt 1 of the first embodiment connects both ends of the belt body 10. Therefore, in the massage belt 1, the belt body 10 can be connected to the attachment portion 100 in a ring shape.

[0054] Both ends of the belt body 10 of the massage belt 1 of Example 1 are detachably connected to the attachment parts 100. Therefore, the length of the ring-shaped portion of the massage belt 1 can be easily adjusted by utilizing the detachable ends of the belt body 10.

[0055] The attachment part 100 of the massage belt 1 of the first embodiment has an attachment part main body 110 extending in the vibration direction of the vibration part 20 when attached to the vibration part 20 of the massage tool 2, and a belt connecting part 130 connecting both ends of the belt main body 10 side by side in the vibration direction. Therefore, the massage belt 1 can transmit the vibration of the vibration part 20 of the massage tool 2 to both ends of the belt main body 10 in a well-balanced manner.

[0056] The attachment section 100 of the massage belt 1 of the first embodiment has a belt connecting section 130 that connects the ends of the belt body 10, and the belt connecting section 130 has a first through hole 135 and a second through hole 137 formed therein, and when both ends of the belt body 10 are passed through the first through hole 135 and the second through hole 137 and folded back and overlapped, the overlapped portions of the belt body 10 are detachably joined by hook-and-loop fasteners 11, 12. Therefore, the massage belt 1 allows the degree of overlap of the ends of the belt body 10 to be easily changed, and therefore the length of the ring-shaped portion can be easily adjusted.

[0057] The massage belt 1 of the first embodiment includes a handle 300 that is connected to the other end of the belt body 10 removed from the attachment part 100. Therefore, the massage belt 1 can be used by selecting either a method in which the handle 300 is not connected to the belt body 10 and the belt body 10 is hung in a ring shape, or a method in which the handle 300 is connected to the other end of the belt body 10.

[0058] The vibration section 20 to which the massage belt 1 of the first embodiment is detachably attached extends in the vibration direction, has an open tip, and forms a recess 20A whose inner circumference in a cross-sectional shape perpendicular to the vibration direction is circular. The vibration section 20 may include a female threaded section 21 provided on the inner peripheral surface at the rear side of the recess 20A, and a non-female threaded section 23 provided on the opening side of the recess 20A relative to the female threaded section 21, which has no threads on its inner peripheral surface and has an inner diameter larger than the valley diameter of the female threaded section 21. The attachment part 100 of the massage belt 1 of Example 1, when inserted into the recess 20A and attached to the vibration part 20, has an attachment part main body 110 whose outer periphery in a cross-sectional shape perpendicular to the vibration direction is circular, and the attachment part main body 110 is provided on the outer periphery surface of the tip part and is equipped with a male threaded part 111 which is screwed into the female threaded part 21, and a non-male threaded part 113 which is provided rearward of the male threaded part 111, has no threads on its outer periphery, and has an outer diameter slightly larger than the outer diameter of the male threaded part 111 and slightly smaller than the inner diameter of the non-female threaded part 23, and the axial length of the male threaded part 111 is shorter than the axial length of the non-female threaded part 23, and the combined axial length of the male threaded part 111 and the non-male threaded part 113 is longer than the axial length of the non-female threaded part 23. Therefore, when the attachment body 110 of this massage belt 1 is inserted into the recess 20A of the vibration part 20, the outer diameter of the male threaded part 111 is slightly smaller than the inner diameter R2 of the non-female threaded part 23 and is almost the same, so that the massage belt 1 can be easily positioned at the opening of the recess 20A by the outer circumferential front end of the male threaded part 111 and the inner peripheral surface of the non-female threaded part 23. Also, in this massage belt 1, the non-male threaded part 113 of the attachment body 110 is inserted into the non-female threaded part 23 of the vibration part 20 before the male threaded part 111 of the attachment body 110 reaches the female threaded part 21 of the vibration part 20. At this time, since the outer diameter of the non-male threaded part 113 is slightly smaller than the inner diameter of the non-female threaded part 23, the outer peripheral surface of the non-male threaded part 113 moves along the inner peripheral surface of the non-female threaded part 23. Therefore, by simply inserting the attachment part into the recess 20A of the vibration part 20, the male threaded part 111 of the attachment part body 110 can be moved to a position where it can be screwed into the female threaded part 21 of the vibration part 20. In this way, the massage belt 1 allows the male threaded part 111 of the attachment part body 110 to be easily screwed into the female threaded part 21 of the vibration part 20 without visually checking the position of the female threaded part 21 of the vibration part 20.

[0059] The present invention is not limited to the first embodiment described above with reference to the drawings, and the following embodiments are also included within the technical scope of the present invention.

The base portion 510 is flat and has a substantially square shape with one side having the same length as the width direction of the belt body 10. The base portion 510 is integrally provided with a male hook-and-loop fastener on the back surface. Therefore, the attachment 500 can be detachably attached to any position on the one surface of the massage belt 1 on which the female hook-and-loop fastener 11 is provided. The protruding portion 520 is provided protruding from the surface of the base portion 510. The shape of the protruding portion 520 may be substantially hemispherical, truncated cone, cone, or the like, as shown in FIG. 13. In addition, a plurality of protruding portions may be protruding from the surface of the base portion 510. By attaching the attachment 500 to the massage belt 1, the protruding portion 520 can be used so as to come into contact with the part to be massaged, thereby obtaining a finger pressure effect.

[0060] (2) The width of the belt body is not limited to that of the belt body of Example 1. For example, the width of the belt body may be about 1 / 2 to 2 times the width of the belt body of Example 1. (3) The belt body may have other shapes instead of a flat belt shape. For example, as shown in Fig. 14(A), it may have a shape that meanders in the width direction. In this case, for example, a flat belt body having a width of 60 mm may have a meandering shape in which convex parts having a maximum size of 1 / 8 times the width of the belt body are continuously provided from both ends extending in parallel. Also, as shown in Fig. 14(B), the belt body may have a shape in which, for example, circular parts having a diameter of 60 mm are connected to extend in one direction. (4) The belt body may have a non-removable protrusion on its surface. In this case, the protrusion may have a plurality of protrusions with a height of about 5 mm for anti-slip purposes or finger pressure. (5) One point of the ring-shaped belt body may be connected to the attachment portion.

[0061] (6) Only one end of the belt body may be detachably connected to the attachment portion. (7) The attachment parts may be connected to both ends of the belt body without arranging them in the vibration direction. For example, they may be connected to each other in a direction perpendicular to the vibration direction. (8) Only one through hole may be formed in the belt connecting portion of the attachment portion, and the end of the belt body and the through hole may be connected via a separate member such as a metal fitting. (9) The length of the belt body of the massage belt in Example 1 is adjusted by folding back both ends and removably joining the overlapping portions with a hook-and-loop fastener. However, the length of the belt body may be adjusted by other structures. (10) The massage belt need not have a handle. (11) The structure for attaching the mounting part to the vibrating part does not have to be the structure of Example 1. The sizes of the vibrating part and the mounting part are not limited to the values ​​of Example 1, and may be changed as appropriate as long as the relative sizes of the two are consistent.
