Description

[Technical field]

[0001] The present invention relates to a wrist wrap. [Background technology]

[0002] The wrist is a movable part of the human body, and may need to be immobilized depending on the type of exercise. For example, when performing an action that requires the wrist to snap, such as spiking a volleyball ball, the wrist may be dorsiflexed and injured, so a wrist supporter with a rigid core material made of a rigid plate has been proposed (for example, Patent Document 1).

[0003] In addition to the above-mentioned exercises, there are other exercises that require the wrist to be fixed. Specifically, in weightlifting, when lifting dumbbells or barbells, if the wrist moves, there is a high possibility of injuring the wrist or reducing the training effect, so it is preferred not to move the wrist during the exercise. Therefore, weightlifting is sometimes performed with a wrist wrap wrapped around the wrist to fix the wrist. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2017-122287 A Summary of the Invention [Problem to be solved by the invention]

[0005] Wrist wraps made of highly elastic materials can easily conform to the surface of the wrist, improving adhesion to the wrist. This means that the wrist wrap is less likely to slip off the wrist while lifting weights, and as a result, the wrist is less likely to rub against the wrist wrap. On the other hand, wrist wraps made of highly elastic materials tend to be soft, which means that they do not provide as much support for the wrist.

[0006] Conversely, wrist wraps made of a material with low elasticity are hard and can improve the fixation of the wrist, but they tend to lose their ability to conform to the surface of the wrist, reducing their adhesion to the wrist, which can result in the wrist rubbing against the wrist wrap and causing pain to the user.

[0007] The present invention has been made in consideration of the above circumstances, and has an object to provide a wrist wrap that can both adhere closely to the wrist and immobilize the wrist. [Means for solving the problem]

[0008] [1] According to the present invention, there is provided a wrist wrap for immobilizing the wrist when gripping a weightlifting handlebar, the wrist wrap comprising a long band-shaped member wrapped around the wrist, the band-shaped member having first and second band-shaped portions, the first band-shaped portion being more elastic than the second band-shaped portion and having a starting portion which is the end portion where the band-shaped member begins to be wound, and the second band-shaped portion being connected to the first band-shaped portion and having a terminal portion which is the end portion where the band-shaped member ends to be wound.

[0009] In the present invention, the first band-like portion having a starting end portion that is the end portion on the wrapping start side is configured to be more elastic than the second band-like portion. This allows the user to wrap the first band-like portion, which is more elastic than the second band-like portion, around the surface of the wrist to improve adhesion between the band-like member and the wrist, and also allows the user to wrap the second band-like portion over the first band-like portion to improve fixation of the wrist. In this way, the wrist wrap of the present invention can achieve both adhesion to the wrist and fixation of the wrist.

[0010] Various embodiments of the present invention will be described below. The embodiments described below can be combined with each other.

[0011] [2] Preferably, there is provided a wrist wrap as described in [1], wherein when the elongation rate of the first band portion is R1 and the elongation rate of the second band portion is R2, R1 / R2 ≧ 1.5 is satisfied. [3] Preferably, there is provided a wrist wrap as described in [1] or [2], further comprising an engagement portion, the engagement portion having first and second engagement portions engageable with each other, the first engagement portion being provided at the terminal portion, and the second engagement portion being provided at at least one of the first band portion and the second band portion. [4] Preferably, there is provided a wrist wrap as described in any one of [1] to [3], further comprising a hook portion, the hook portion being provided at the starting end and configured to allow a finger to be hooked thereon. [5] Preferably, there is provided a wrist wrap as described in any one of [1] to [4], wherein the second band has a connecting portion overlapping an outer surface of the first band, and the second band is connected to the first band at the connecting portion.

[Figure 4]Fig. 4A is a plan view of the second band-shaped portion 1b, Fig. 4B is a plan view of the first band-shaped portion 1a, and Fig. 4C is an enlarged view of region B shown in Fig. 1B. [Diagram 5] FIG. 5 shows the state in which the hook portion 2a of the wrist wrap 100 is inserted around the thumb. [Figure 6] FIG. 6 shows the state in which the first band-shaped portion 1a is wrapped around the wrist, following the state shown in FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Various characteristic features shown in the following embodiment can be combined with each other. Also, each characteristic feature can be an invention independently.

[0014] 1. Configuration of the embodiment In the embodiment, a wrist wrap attached to a right hand will be described. A wrist wrap attached to a left hand will not be described because the shape is symmetrical. A wrist wrap 100 according to an embodiment is used when gripping a handle bar for weightlifting, and is capable of immobilizing the wrist. As shown in Figures 1A to 1C, the wrist wrap 100 includes a belt-shaped member 1, a hook portion 2, and an engagement portion 3.

[0015] 1-1. Belt-shaped member 1 1-1-1. Configuration of belt-shaped member 1 The belt-shaped member 1 shown in Fig. 1A is a long member that is wrapped around the wrist. The belt-shaped member 1 has a first belt-shaped portion 1a and a second belt-shaped portion 1b. As shown in Figs. 1B and 4C, the wrist wrap 100 has an overlapping region Rg where the first belt-shaped portion 1a and the second belt-shaped portion 1b overlap.

[0016] As shown in Fig. 4B, the first band-shaped portion 1a is a long rectangular member made of a stretchable material. The first band-shaped portion 1a is made to have higher stretchability than the second band-shaped portion 1b. In other words, the stretchability of the material constituting the first band-shaped portion 1a is higher than that of the material constituting the second band-shaped portion 1b.

[0017] As shown in FIGS. 1A to 2A and 4B, first band-shaped portion 1a has a starting end portion 1a1, a connecting portion 1a2, an outer side surface 1a3, and an inner side surface 1a4. The starting end 1a1 is an end on the winding start side of the belt-shaped member 1. The starting end 1a1 is provided with a hook portion 2 shown in Figs. 2B and 2C. The connecting portion 1a2 is overlapped and connected to the connecting portion 1b2 of the second belt-shaped portion 1b. The connecting portion 1a2 is located on the end side opposite the starting end portion 1a1 in the longitudinal direction of the belt-shaped member 1. The outer surface 1a3 and the inner surface 1a4 are formed to extend from the starting end 1a1 to the connecting portion 1a2. The outer surface 1a3 is the surface on which the second band-shaped portion 1b is placed when the band-shaped member 1 is wrapped around the wrist, and the inner surface 1a4 is the surface that comes into contact with the wrist when the band-shaped member 1 is wrapped around the wrist. In other words, the connecting portion 1a2 has the first band-shaped portion 1a located on the wrist side and the second band-shaped portion 1b located on the outside, preventing the relatively hard second band-shaped portion 1b from coming into direct contact with the wrist.

[0018] As shown in Figures 1A to 2A and 4A, the second band-shaped portion 1b is a long rectangular member made of a stretchable material. The second band-shaped portion 1b is less stretchable than the first band-shaped portion 1a, but is harder than the first band-shaped portion 1a to compensate for the lower stretchability. The second band-shaped portion 1b has an end portion 1b1, a connecting portion 1b2, an outer surface 1b3, and an inner surface 1b4. The terminal end 1b1 is an end portion on the winding end side of the belt-shaped member 1. A first engaging portion 3a of the engaging portion 3, which will be described later, is provided on the terminal end 1b1. The connecting portion 1b2 overlaps the outer surface 1a3 of the first band-shaped portion 1a and is connected to the first band-shaped portion 1a at the connecting portion 1a2. The connecting portion 1b2 is located on the end side opposite the terminal end portion 1b1 in the longitudinal direction of the band-shaped member 1. The connecting portion 1a2 and the connecting portion 1b2 are provided in the overlapping region Rg. The outer surface 1b3 and the inner surface 1b4 are formed to extend from the terminal end 1b1 to the connecting portion 1b2. A second engagement portion 3b of the engagement portion 3, which will be described later, is provided on the outer surface 1b3. Furthermore, at least a portion of the inner surface 1b4 is in contact with and overlaps the outer surface 1a3 of the first band-shaped portion 1a when the band-shaped member 1 is wrapped around the wrist.

[0019] 1-1-2. Materials Constituting the First Belt-Shaped Portion 1a and the Second Belt-Shaped Portion 1b The first belt-shaped portion 1a and the second belt-shaped portion 1b are configured to include a first material and a second material, but the mixing ratios of the first material and the second material are different.

[0020] In the embodiment, the first material is polyester. For example, Dacron (registered trademark) can be used as the first material. Although the first material is preferably polyester, it may contain other materials (for example, at least one of cotton, rayon, polyurethane, nylon, and polyurethane) to some extent.

[0021] In an embodiment, the second material is latex, which may be natural or synthetic latex.

[0022] In the embodiment, the first belt-shaped portion 1a is composed of a first material and a second material. That is, in the first belt-shaped portion 1a, the sum of the mixture ratio t1 of the first material in the first belt-shaped portion 1a and the mixture ratio t2 of the second material in the first belt-shaped portion 1a is 100%. Similarly, in the second belt-shaped portion 1b, the sum of the mixture ratio q1 of the first material in the second belt-shaped portion 1b and the mixture ratio q2 of the second material in the second belt-shaped portion 1b is 100%.

[0023] The mixture ratio t1 of the first material in the first belt-shaped portion 1a is higher than the mixture ratio q1 of the first material in the second belt-shaped portion 1b. The mixture ratio t2 of the second material in the first belt-shaped portion 1a is lower than the mixture ratio q2 of the second material in the second belt-shaped portion 1b. Due to this blend ratio, the first band-shaped portion 1a is more elastic than the second band-shaped portion 1b and is wrapped around the surface of the wrist, enhancing the adhesion between the band-shaped member 1 and the wrist. The second band-shaped portion 1b is also harder than the first band-shaped portion 1a, and is wrapped around the first band-shaped portion 1a to enhance the fixation of the wrist.

[0024] The mixing ratio t1 (%) of the first material in the first belt-shaped portion 1a is, for example, 68, 69, 70, 71, 72, 73, 74, or 75, and may be within a range between any two of the values ​​exemplified here. The mixing ratio t2 (%) of the second material in the first belt-shaped portion 1a is 100-t1.

[0025] The mixing ratio q1 (%) of the first material in the second belt-shaped portion 1b is, for example, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, and may be within a range between any two of the values ​​exemplified here. The mixing ratio q2 (%) of the second material in the second belt-shaped portion 1b is 100-q1.

[0026] 1-1-3. Dimensions of belt-shaped member 1 As shown in FIG. 4B, the longitudinal length WL1 (cm) of the first band-shaped portion 1a is specifically, for example, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, or 30, and may be within a range between any two of the numerical values ​​exemplified here.

[0027] The length WS1 (cm) of the first strip portion 1a in the short side direction is specifically, for example, 5.0, 5.5, 6.0, 6.5, 7.0, 7.5, 8.0, 8.5, 9.0, 9.5, or 10.0 cm, and may be within a range between any two of the numerical values ​​exemplified here.

[0028] The thickness T1 (mm) of the first band-shaped portion 1a shown in FIG. 4C is specifically, for example, 2.0, 2.2, 2.4, 2.6, 2.8, 3.0, 3.2, 3.4, 3.6, 3.8, or 4.0 mm, and may be within a range between any two of the numerical values ​​exemplified here.

[0029] As shown in FIG. 4A, the longitudinal length WL2 (cm) of the second band-shaped portion 1b is specifically, for example, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 28, or 30, and may be within a range between any two of the numerical values ​​exemplified here.

[0030] Specifically, the length WS2 (cm) of the second band-shaped portion 1b in the short side direction is, for example, 5.0, 5.5, 6.0, 6.5, 7.0, 7.5, 8.0, 8.5, 9.0, 9.5, or 10.0 cm, and may be within a range between any two of the numerical values ​​exemplified here. The length WS2 of the second band-shaped portion 1b in the short side direction is preferably the same as the length WS1 of the first band-shaped portion 1a in the short side direction. This is because, when the band-shaped member 1 is wrapped around the wrist, it is possible to prevent the edge of the band-shaped member 1 (the edge that forms a spiral when wrapped around the wrist) from becoming uneven, thereby improving the aesthetic appearance.

[0031] The thickness T2 (mm) of the second band-shaped portion 1b shown in FIG. 4C is, for example, 2.0, 2.3, 2.6, 2.9, 3.2, 3.5, 3.8, 4.1, 4.4, 4.7, or 5.0 mm, and may be within a range between any two of the numerical values ​​exemplified here. The thickness T2 of the second band-shaped portion 1b is preferably greater than the thickness T1 of the first band-shaped portion 1a. This is because not only are the materials of the first band-shaped portion 1a and the second band-shaped portion 1b different, but by increasing the thickness, the hardness of the second band-shaped portion 1b can be further increased.

[0032] The longitudinal length (cm) of the overlap region Rg of the first band-shaped portion 1a and the second band-shaped portion 1b is specifically, for example, 4, 5, 6, 7, 8, 9, 10, 11, or 12 cm, and may be within a range between any two of the numerical values ​​exemplified here.

[0033] 1-1-4. Growth rate The extensibility of the first belt-shaped portion 1a is R1, and the extensibility of the second belt-shaped portion 1b is R2. The extensibility corresponds to the stretchability of the belt-shaped member 1. In the embodiment, R1 is greater than R2.

[0034] The elongation rate R1 (%) of the first band portion 1a is defined as follows based on the total longitudinal length Lw1 when the upper end of the first band portion 1a is fixed and a weight of 5 kg is hung from the lower end, and the longitudinal length Lf1 of the first band portion 1a when no weight is hung, as shown in Equation 1 below. R1=((Lw1-Lf1) / Lf1)×100...Equation 1 Here, the length Lf1 in the longitudinal direction of the first band-shaped portion 1a when no weight is hung therefrom is 20 cm. Furthermore, the length of the first band-shaped portion 1a in the short direction when no weight is hung therefrom is 8 cm. Furthermore, the thickness of the first band-shaped portion 1a when no weight is hung therefrom is 3 mm.

[0035] The value of the elongation percentage R1 (%) is specifically, for example, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, or 150, and may be within a range between any two of the values ​​exemplified here. The value of the elongation percentage R1 (%) is preferably 50 or more, and more preferably 80 or more.

[0036] Similarly, the elongation rate R2 (%) of the second band portion 1b is defined as follows based on the total longitudinal length Lw2 when the upper end of the second band portion 1b is fixed and a 5 kg weight is hung from the lower end, and the natural longitudinal length Lf2 of the second band portion 1b (the longitudinal length when no weight is hung), as shown in Equation 2 below. R2=((Lw2-Lf2) / Lf2)×100...Equation 2 Here, the length Lf2 in the longitudinal direction of the second band-shaped portion 1b when no weight is hung therefrom is 27 cm. Furthermore, the length of the second band-shaped portion 1b in the short direction when no weight is hung therefrom is 8 cm. Furthermore, the thickness of the second band-shaped portion 1b when no weight is hung therefrom is 3.5 mm.

[0037] The value of the elongation rate R2 (%) is specifically, for example, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, or 30, and may be within a range between any two of the numerical values ​​exemplified here.

[0038] Moreover, the ratio of the elongations, R1 / R2, is preferably 2 or more. Specifically, R1 / R2 may be, for example, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 25, 30, 35, 40, 45, or 50, and may be within a range between any two of the numerical values ​​exemplified here.

[0039] 1-2. Hook section 2 3A and 3B, the hook part 2 is configured so that a finger can be hooked thereon. The hook part 2 has a hook part 2a and a connecting part 2b. The hook portion 2a is formed in a ring shape, and a finger can be inserted into it. As shown in Fig. 5 and Fig. 6, in the embodiment, the thumb of a hand is passed through the hook portion 2a, which can be used to determine the position where the belt-shaped member 1 starts to be wound. The connecting portion 2b is a belt-shaped member connected to the hook portion 2a. The connecting portion 2b is fixed to the portion of the outer surface 1a3 of the first belt-shaped portion 1a where the starting end 1a1 is formed. In the embodiment, the hook portion 2 is sewn to the first belt-shaped portion 1a and fixed to the first belt-shaped portion 1a. The hook portion 2a extends in a direction perpendicular to the longitudinal direction of the belt-shaped member 1 at the end of the first belt-shaped portion 1a. However, the hook portion 2a may be configured to extend at an angle with respect to the direction perpendicular to the longitudinal direction of the belt-shaped member 1. As shown in FIG. 1A and FIG. 2A, the hook portion 2 is configured of a belt-shaped member, but may be string-shaped. In addition, the direction in which the hook portion 2a extends from the first belt-shaped portion 1a may extend in the opposite direction to that shown in FIG. 1A and FIG. 2A.

[0040] 1-3. Engagement part 3 1A to 1C, the engagement part 3 is configured to hold the belt-shaped member 1 wrapped around the wrist. The engagement part 3 has a first engagement part 3a and a second engagement part 3b.

[0041] The first engagement portion 3a and the second engagement portion 3b are formed with hook-and-loop fasteners that can be connected to each other. As a result, when the user finishes wrapping the belt-shaped member 1 around his / her wrist, the first engagement portion 3a, which is one of the hook-and-loop fasteners, can be pressed against the second engagement portion 3b, which is the other of the hook-and-loop fasteners, thereby engaging the first engagement portion 3a with the second engagement portion 3b and maintaining the belt-shaped member 1 wrapped around the wrist.

[0042] The first engagement portion 3a is fixed to a portion of the inner surface 1b4 of the second band-shaped portion 1b where the end portion 1b1 is formed. The first engagement portion 3a is sewn to the second band-shaped portion 1b and fixed to the second band-shaped portion 1b.

[0043] The second engagement portion 3b is fixed to the outer surface 1b3 of the second band-shaped portion 1b. The fixed position of the second engagement portion 3b is closer to the connecting portion 1b2 than to the terminal end portion 1b1 in the longitudinal direction of the band-shaped member 1. The second engagement portion 3b is sewn to the second band-shaped portion 1b and fixed to the second band-shaped portion 1b.

[0044] The second engagement portion 3b may be provided on at least one of the first band-shaped portion 1a and the second band-shaped portion 1b depending on the dimensions of the band-shaped member 1. In other words, the second engagement portion 3b may be provided only on the first band-shaped portion 1a as in the embodiment, or, although not shown, may be provided only on the second band-shaped portion 1b, or may be provided on both the first band-shaped portion 1a and the second band-shaped portion 1b.

[0045] 2. How to wear Wrist Wrap 100 and explanation of its action and effect As shown in FIG. 5, the user inserts his / her thumb into the hook portion 2a and hooks the thumb on the hook portion 2a. Next, as shown in FIG. 6, the user wraps the band-shaped member 1 around his / her wrist while pulling the band-shaped member 1 or the engagement portion 3 to apply tension. Here, the portion that comes into contact with the wrist is the first band-shaped portion 1a, which has high conformability to the surface of the wrist, so that the occurrence of a gap between the wrist and the inner surface of the first band-shaped portion 1a is suppressed, and the wrist wrap 100 adheres closely to the wrist. As a result, the wrist is prevented from rubbing against the wrist wrap, and the user can avoid feeling pain when using the wrist wrap 100.

[0046] When the user has finished wrapping the first band-shaped portion 1a around the wrist, the user pulls the second band-shaped portion 1b or the engagement portion 3 to apply tension, and then wraps the second band-shaped portion 1b over the first band-shaped portion 1a already wrapped around the wrist. The second band-shaped portion 1b, which is relatively harder than the first band-shaped portion 1a, is wrapped over the first band-shaped portion 1a, so that the wrist wrap 100 has a high degree of fixation of the wrist. In this way, the wrist wrap 100 according to the embodiment can achieve both close contact with the wrist and fixation of the wrist.

[0047] When the user has finished wrapping the second belt-shaped portion 1b, he or she presses the first engagement portion 3a onto the second engagement portion 3b to engage the first engagement portion 3a with the second engagement portion 3b, thereby keeping the belt-shaped member 1 wrapped around the wrist.

[0048] 3. Other embodiments In the embodiment, the components are connected by being sewn together, but this is not limited to this. That is, in the embodiment, the first engaging portion 3a and the second belt-shaped portion 1b are sewn together, the second engaging portion 3b and the second belt-shaped portion 1b are sewn together, the first belt-shaped portion 1a and the second belt-shaped portion 1b are sewn together, and the first belt-shaped portion 1a and the hook portion 2 are sewn together, but this is not limited to this. The components may be connected to each other by other connecting means, such as a cotton fastener. In the embodiment, the engaging portion 3 is described as having a pair of hook-and-loop fasteners, so that the first engaging portion 3a and the second engaging portion 3b engage with each other, but this is not limited thereto. For example, the engaging portion 3 may have a structure for recessed and protruding engagement. For example, the first engaging portion 3a may be a button sewn to the second belt-shaped portion 1b, and the second engaging portion 3b may be a hole formed at a predetermined position of the belt-shaped member 1 into which the button can be inserted. The second engagement portion 3b may be disposed in the overlapping region Rg or in the first band-shaped portion 1a. The second band-shaped portion 1b has a tapered shape at the formation site of the terminal end 1b1, but is not limited to this, and the planar shape of the entire second band-shaped portion 1b may be rectangular, similar to the first band-shaped portion 1a. The tapered shape of the end portion 1b1 of the second band-shaped portion 1b may be formed by cutting a rectangular material, or by bending a rectangular material. [Explanation of symbols]
