Description

The present invention relates to the structure of a stay attached to a supporter.

Supporters that protect joints such as knees and elbows are generally provided with stays that are applied to the sides of the joints. The stay is an elongated member having appropriate rigidity and elasticity, and is appropriately positioned on the supporter to reduce the burden on the joint.

Such a stay is attached in a manner to be accommodated in an accommodating portion provided in the supporter, and many of them have a flat structure with a constant thickness in order to ensure a stable attachment state (see Patent Document 1). . For example, in a knee supporter, a pair of stays are positioned inside and outside the knee, respectively, and are arranged so that their flat surfaces face the sides of the knee.

JP 2011-212093 A

The stay of Patent Literature 1 has a constant plate thickness over the entire length, while the plate width at the center in the longitudinal direction is locally reduced. As a result, the bendability of the central part of the stay is increased, making it easier for the supporter to follow the bending motion of the knee joint, while the rigidity of positions other than the central part is secured to stably support the knee joint from the left and right. , reduces the load on the joints.

However, such a stay has high rigidity except for the central portion. Therefore, when the user wearing the supporter bends and stretches, the ends of the stay may locally press the surface of the thigh or calf, causing pain or discomfort. Such problems are not limited to the knee supporter, and may similarly arise with other supporters such as the elbow.

SUMMARY OF THE INVENTION The present invention has been made in view of such problems, and one of its purposes is to provide a stay that does not make the user feel uncomfortable when using the supporter.

One aspect of the present invention is a stay attached to a supporter to protect joints. The stay has a flexible, flat elongated main body, and the direction in which the main body is likely to bend differs between both end portions in the longitudinal direction of the main body and the central portion thereof.

Another aspect of the present invention is a supporter. This supporter includes a supporter body that is attached to cover the joint, a stay that protects the joint, and an accommodating portion that is provided in the supporter body and accommodates the stay. The stay has a flat and elongated shape with flexibility, and the directions of easy bending are different between the longitudinal ends and the central part.

According to the present invention, it is possible to provide a stay that does not make the user feel uncomfortable when using the supporter.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
The supporter of this embodiment includes a pair of stays for protecting the user's joints. The stay has appropriate rigidity and elasticity, and the flexible direction differs between the ends and the central portion in the longitudinal direction. As a result, the holding function of the joint can be strengthened without impeding the joint movement, and the user can be prevented from feeling discomfort such as a local pressure feeling when using the supporter. A specific configuration thereof will be described in detail below.

(Supporter composition)
FIG. 1 is a diagram showing a supporter according to an embodiment. FIG. 1(A) is a front view, and FIG. 1(B) is a rear view. In the following description, for convenience, up/down, left/right, and forward/backward directions are expressed based on the direction viewed from the user wearing the supporter.

The supporter 1 is a knee supporter worn so as to cover the user's knee joint. The supporter 1 has a tubular supporter body 10 into which a user's one leg can be inserted. The supporter main body 10 is made of fabric having moderate elasticity. As shown in FIG. 1A, an opening 12 for exposing the kneecap is provided in the center of the front surface of the supporter body 10 . On the left and right side surfaces of the supporter main body 10, housing portions 14 for housing a pair of stays, which will be described later, are respectively provided.

A first strap 16 and a second strap 18 extend forward from the upper left side surface of the supporter body 10 and the second strap 18 extend forward from the upper right side surface, respectively, and are detachably connected to each other by hook-and-loop fasteners. A third strap 20 extends forward and downward from the center of the left side of the supporter body 10, and a fourth strap 22 extends forward and downward from the center of the right side of the supporter body 10, and can be attached to and detached from the front side of the supporter body 10 by hook-and-loop fasteners. connected to

As shown in FIG. 1(B), a mesh fabric 28 is adopted in the center of the back side of the supporter body 10, and the stretchability and breathability of that part are enhanced. In this embodiment, a double raschel structure is adopted as the mesh fabric 28, but the details thereof will be omitted. Elastic straps 24 and 26 are arranged on the upper half of the back surface of the supporter body 10 so as to cross each other.

The elastic strap 24 is provided so as to span the upper left side surface and the central portion of the right side surface of the supporter body 10 . The elastic strap 26 is provided so as to span the upper right side surface and the central left side surface of the supporter body 10 . As a result, the spread of the supporter main body 10 during bending and stretching can be suppressed, and the thigh holding function can be reinforced.

FIG. 2 is a diagram showing the state (opened state) before the supporter 1 is attached to the joint.
The front side surface of the supporter main body 10 has a structure that can be opened and closed to the left and right below the opening 12 . That is, the lower left front portion 30 and the lower right front portion 32 of the supporter body 10 overlap each other, and are detachable by hook-and-loop fasteners. A loop surface 34 of a hook-and-loop fastener is provided on the outer surface of the lower left front portion 30 , and a hook surface 36 of the hook-and-loop fastener is provided on the inner surface of the lower right front portion 32 .

By separating the lower right front portion 32 from the lower left front portion 30 and opening the lower portion of the supporter main body 10, insertion of the foot into the supporter 1 is facilitated. By attaching the lower right front portion 32 to the lower left front portion 30, the lower half of the supporter main body 10 becomes cylindrical and the opening 12 is formed. A hook-and-loop fastener loop surface 38 is also provided on the outer surface of the lower right front portion 32 .

A loop surface 40 of a hook-and-loop fastener is provided on the outer surface of the first strap 16, and a hook surface 42 of the hook-and-loop fastener is provided on the inner surface of the second strap 18, so that both can be attached and detached. By attaching the first strap 16 and the second strap 18, the upper half of the supporter body 10 can be firmly fixed to the thigh of the user.

The third strap 20 and the fourth strap 22 are each bifurcated at the base ends and connected to the left and right side surfaces of the supporter body 10 . A hook surface 44 that can be attached to and detached from the loop surface 38 of the lower right front portion 32 is provided on the inside surface of the distal end portion of the third strap 20 . On the other hand, a hook surface 46 that can be attached to and detached from the loop surface 34 of the lower left front portion 30 is provided on the inside surface of the distal end portion of the fourth strap 22 .

The lower right front section 32 is connected to the lower left front section 30 while exposing the user's kneecaps through the opening 12 . By connecting the third strap 20 to the lower right front portion 32 and connecting the fourth strap 22 to the lower left front portion 30 in this state, the lower half of the supporter body 10 can be firmly fixed to the shin of the user.

FIG. 3 is a diagram showing how the supporter is attached to the knee joint. This figure shows a state in which the user wears the supporter and slightly bends the knee joint.
A housing portion 14 extends vertically along the side surface of the supporter 1, and a stay 50 is housed therein. The accommodating portion 14 is made of a long cloth bag, and is sewn to the side surface of the supporter main body 10 in a state in which the stay 50 is accommodated in advance.

When the knee joint is bent as shown in the figure, the supporter 1 and the stay 50 are also bent and deformed accordingly. The pair of accommodating parts 14 are provided at symmetrical positions when viewed from the front of the supporter 1, and support and protect the knee joint from the left and right.

(Stay configuration)
Next, the configuration of the stay 50 will be described. In the following description, for convenience, the positional relationship of each structure may be expressed based on the illustrated state.
FIG. 4 is a diagram showing the configuration of the stay 50. As shown in FIG. 4A is a perspective view of the stay 50, and FIG. 4B is a perspective view of the core member 56 that constitutes the stay 50. FIG.

As shown in FIG. 4A, the stay 50 has a flexible flat elongated main body 52 . The main body 52 is configured by embedding a core member 56 in a stay main body 54 . The stay main body 54 constitutes the outer shape of the stay 50 . The core member 56 has an elongated shape and extends inside the stay body 54 over both ends.

As also shown in FIG. 4B, a protrusion 58 is provided at the center of the upper surface of the core member 56 . The protrusion 58 extends in the axial direction with a constant width. A protrusion 58 is exposed on the upper surface (one side surface in the thickness direction) of the stay main body 54 . Both the stay main body 54 and the core member 56 are made of resin, but the core member 56 is harder than the stay main body 54 . For example, nylon is used as the material of the core member 56 and polyurethane is used as the material of the stay main body 54 .

In this embodiment, when manufacturing the stay 50, first, the core member 56 is produced by injection molding of a first resin material using a first mold (not shown). Then, the core member 56 is set in a second mold (not shown) and a second resin material is injected to integrally mold the stay body 54 with the core member 56 . Note that, in a modified example, the stay 50 may be manufactured by extrusion molding, in-mold foaming, or other molding methods. Alternatively, the stay main body 54 and the core member 56 may be manufactured separately, and the stay 50 may be configured by assembling them.

FIG. 5 is a diagram showing details of the stay 50. As shown in FIG. 5(A) is a plan view, FIG. 5(B) is a side view, FIG. 5(C) is a bottom view, and FIG. 5(D) is a sectional view taken along line AA in FIG.
As shown in FIG. 5(A), the stay body 54 has a symmetrical structure with respect to the center line L in the longitudinal direction. As also shown in FIGS. 5(C) and (D), the stay body 54 covers most of the core member 56 . The stay main body 54 has a substantially rectangular shape in plan view, and both ends thereof are chamfered. The stay main body 54 has a generally constant width over its entire length, but the width at both ends is slightly larger than the width at the central portion.

As shown in FIGS. 5A and 5B, a plurality of cutouts 60 are arranged at regular intervals on both side surfaces of the stay body 54 in the width direction. Each notch 60 extends in the thickness direction of the stay body 54 and has a semicircular shape in plan view. The plurality of cutouts 60 are located near the center in the longitudinal direction of the stay body 54 and are provided in pairs in the width direction of the stay body 54 . The width of the stay main body 54 is sufficiently larger than the width of the core member 56 even at the position where the notch 60 is provided. In other words, since the central portion in the longitudinal direction of the core member 56 is narrow, it is easy to form the notch portion 60 in the central portion in the longitudinal direction of the stay main body 54 .

FIG. 6 is a diagram showing the details of the core member 56. As shown in FIG. 6(A) is a plan view, FIG. 6(B) is a side view, FIG. 6(C) is a bottom view, and FIG. 6(D) is a sectional view taken along line AA in FIG. 6(A).
As shown in FIGS. 6A to 6D, the core member 56 has a shape with a smaller width and a larger thickness at the central portion in the longitudinal direction than at both ends. The core member 56 has a symmetrical structure with respect to the longitudinal centerline L, and both ends thereof are chamfered. The core member 56 has a shape transition portion 62 in which the width gradually decreases and the thickness gradually increases from both ends in the longitudinal direction toward the central portion. A protrusion provided at the center of the upper surface of the core member 56 constitutes a protrusion 58 .

FIG. 7 is a partially enlarged sectional view showing details of the core member 56. As shown in FIG. FIG. 7(A) is a cross-sectional view showing one longitudinal half of the core member 56, and corresponds to FIG. 5(D). FIG. 7(B) is a cross-sectional view taken along line BB of FIG. 7(A). 7 (C) to (F) are respectively a cross-sectional view along the CC arrow, a cross-sectional view along the DD arrow, a cross-sectional view along the EE arrow, and a cross-sectional view along the FF arrow in FIG. 7 (B). be.

The core member 56 has a structure in which the cross-sectional shape changes along the longitudinal direction except for the central portion in the longitudinal direction. As shown in FIGS. 7(C) to (F), the core member 56 gradually decreases in width and gradually increases in thickness in the shape transition portion 62 from the ends toward the central portion in the longitudinal direction. The stay main body 54 also has a portion corresponding to the shape transition portion 62, in which the width gradually decreases from the longitudinal end side to the central portion side and the thickness gradually increases. smaller than that of member 56;

With such a configuration, in the stay 50, the central portion in the longitudinal direction of the main body 52 has a greater geometrical moment of inertia with respect to bending in the thickness direction than at both ends, and both ends have a larger sectional moment of inertia with respect to bending in the width direction than at the central portion. Moment increases. As a result, with respect to the longitudinal direction of the main body 52, the direction in which the main body 52 is likely to bend differs between both end portions and the central portion.

Further, as shown in FIG. 7(F), by providing the projecting portion 58 so as to protrude from one side surface of the stay body 54, the stay 50 as a whole can be kept thin while the core member 56 can be made large in the thickness direction. bending stiffness can be increased.

(Action and effect of the stay)
8 and 9 are diagrams showing bending characteristics of the stay 50 as a whole. A blank arrow in the drawing indicates a bending load acting on the stay 50 .
As shown in FIG. 8, when a bending load F1 in the thickness direction is applied to both ends of the stay 50, the central portion of the main body 52 in the longitudinal direction undergoes little deformation while both ends undergo large deformation. This is because the geometrical moment of inertia related to the bending rigidity in the thickness direction of the core member 56 is relatively large at the central portion in the longitudinal direction and relatively small at both ends.

On the other hand, as shown in FIG. 9, when a bending load F1 in the width direction is applied to both ends of the stay 50, the central portion of the main body 52 in the longitudinal direction is greatly deformed. This is because the geometrical moment of inertia related to the bending rigidity in the width direction of the core member 56 is relatively small at the central portion in the longitudinal direction. In addition, providing a plurality of cutouts 60 along both side surfaces of the stay 50 in the width direction also contributes to ease of bending. The elastic deformation of the stay 50 can be accelerated by narrowing the notch 60 located on the inside in the bending direction and widening the notch 60 located on the outside. The cutout portion 60 realizes a “low-rigidity portion” in the stay 50 that is easily bent in the width direction.

FIG. 10 is a diagram showing the bending characteristics of the ends of the stay 50. As shown in FIG. FIG. 10A shows a case where a load in the thickness direction is applied to the vicinity of the tip of the main body 52 while fixing the position near the center of the end of the main body 52 (the vicinity of the notch 60: see the two-dot chain line). . FIG. 10B shows a case where a load is applied in the width direction to the vicinity of the tip of the body 52 while similarly fixing the position near the center of the end of the body 52 . A blank arrow in the drawing indicates a bending load acting on the stay 50 .

When a bending load F2 in the thickness direction is applied as shown in FIG. 10(A), the ends of the main body 52 are greatly deformed. On the other hand, when a bending load F2 in the width direction is applied as shown in FIG. 10B, the deformation is small. This is because, at the ends of the main body 52 (that is, the stay main body 54 and the core member 56), the geometrical moment of inertia related to the bending rigidity in the thickness direction is smaller than the geometrical moment of inertia related to the bending rigidity in the width direction.

FIG. 11 is a diagram showing a state in which the stay 50 is incorporated into the supporter 1. FIG. FIG. 11(A) is a side view, and FIG. 11(B) is a rear view.
As shown in FIG. 11A, the accommodating portion 14 is made of an elongated bag-like member and is sewn on the side surface of the supporter body 10 so as to extend from the upper end to the lower end. The housing portion 14 includes an upper housing portion 70, a lower housing portion 72, and a connecting portion 74 connecting them. Although the figure shows the left side of the supporter 1, the same configuration is provided on the right side of the supporter 1 (see FIG. 3).

The supporter main body 10 has an upper accommodation portion 70 at its upper portion, a lower accommodation portion 72 at its lower portion, and a connecting portion 74 at its central portion. The connecting portion 74 is located approximately at the height of the opening 12 , the upper accommodating portion 70 extends above the opening 12 , and the lower accommodating portion 72 extends below the opening 12 . The upper part of the stay 50 is accommodated in the upper accommodating part 70, the lower part is accommodated in the lower accommodating part 72, and the central part is accommodated in the connecting part 74, respectively. The connecting portion 74 is made of fabric that is more flexible than the upper housing portion 70 and the lower housing portion 72 .

A thick dashed line in the drawing represents a seam ST of the accommodating portion 14 with respect to the supporter main body 10 . Both the front and rear edges of the upper housing portion 70 and the lower housing portion 72 are sewn to the supporter body 10 . On the other hand, the connecting portion 74 has its front edge sewn to the supporter body 10, but its rear edge is not sewn. That is, the connecting portion 74 is fixed to the supporter body 10 on the side that deforms into a convex shape when the joint is bent, and is not fixed to the supporter body 10 on the side that deforms into a concave shape when the joint is bent.

Therefore, as shown in FIG. 11(B), a gap S is provided between the connecting portion 74 and the supporter main body 10 so as to open rearward. In other words, a configuration is adopted in which the flexibility of the connecting portion 74 is enhanced and the connecting portion 74 is lifted from the supporter main body 10 . As a result, the restraint of the stay 50 attached to the supporter main body 10 is relaxed to facilitate bending in the front-rear direction, thereby making it difficult to hinder the bending motion of the joint.

In the present embodiment, the protrusion 58 is arranged in the accommodation portion 14 so that the protrusion 58 faces the outside of the supporter 1 , that is, is positioned on the side of the stay 50 opposite to the supporter main body 10 . As a result, the relatively soft surface of the stay 50 faces the joint.

Further, the stay 50 is sewn to the supporter main body 10 in a state where the stay 50 is accommodated in the accommodation portion 14 . This reliably prevents the stay 50 from coming off when the supporter 1 is in use. In a modification, an opening such as a slit may be provided in the housing portion 14 so that the stay 50 can be taken in and out.

As described above, in the stay 50 of the present embodiment, the direction in which the stay 50 is likely to bend differs between the longitudinal end portions and the central portion. Therefore, the bending characteristics of the stay 50 can be flexibly adapted to the functions to be added to the supporter 1 . Specifically, the stay 50 has a flat and elongated shape, the central portion of which has a large geometrical moment of inertia regarding bending in the thickness direction, and both ends thereof have a large geometrical moment of inertia regarding bending in the width direction. Therefore, when the flat surface of the stay 50 is placed along the user's joint and its vicinity, the joint can be firmly supported at the central portion, while both ends can be flexibly deformed according to the user's posture.

As a result, by attaching the stay 50, it is possible to strengthen the function of the supporter 1 to hold the joints, and to prevent the user from feeling local pressure when the supporter 1 is used. By applying the stay 50 to the knee supporter as in the present embodiment, flexibility for bending the knee and rigidity for keeping the knee joint from shifting can be ensured at the same time.

Since both the stay main body 54 and the core member 56 are made of elastic resin, the stay 50 is constructed by embedding the relatively hard core member 56 in the relatively soft stay main body 54 . As a result, the contribution of the core member 56 to the bending rigidity of the stay 50 is higher than that of the stay main body 54 . By reducing the width and increasing the thickness of the core member 56 in the central portion in the longitudinal direction of the stay 50, the rigidity in the direction in which the joint is supported is increased, while the bending motion of the joint is less likely to be hindered. ing. That is, according to this embodiment, the lateral stability of the joint can be ensured without interfering with the bending motion of the joint.

In addition, by reducing the thickness and increasing the width of the stay body 54 and the core member 56 at both ends of the stay 50 in the longitudinal direction, the stay 50 is made easy to bend in the thickness direction and difficult to bend in the width direction. As a result, the stay 50 can easily conform to the user's posture at a position away from the joint. On the other hand, the rigidity of the stay 50 can be ensured to such an extent that the front-rear positional deviation does not occur within the supporter 1 . By adopting a soft material for the stay main body 54 that constitutes the outer frame of the stay 50, it is possible to improve the tactile sensation given to the user.

Furthermore, by providing the shape transition portion 62 in the core member 56 to moderate the change in width and thickness, it is possible to avoid local stress concentration when a bending load is applied. As a result, the durability of the stay 50 can be enhanced.

[Modification]
In the above-described embodiment, an example of the flat and elongated stay 50 having a rectangular cross section was shown, but it goes without saying that the specific structure such as the shape and length can be appropriately set. In a modification, the cross-sectional shape of the stay may be rhombic, elliptical, or any other shape. Although a plurality of cutouts 60 are provided in the above embodiment, the shape, number, and arrangement of the cutouts can be changed as appropriate. Also, the notch 60 may be omitted.

In the above-described embodiment, the configuration in which the projecting portion 58 protrudes from one side surface of the stay 50 is exemplified. In a modified example, protrusions may be provided on both one side and the opposite side of the stay. By reducing the thickness of the stay main body, the overall thickness of the stay can be reduced while maintaining the bending rigidity of the core member. Alternatively, the bending rigidity can be further increased by increasing the thickness of the core member while maintaining the thinness of the entire stay.

In the above-described embodiment, an example in which the protrusion 58 is configured as a ridge is shown. In a modification, intermittent projections (a plurality of projections) may be provided along the upper surface of the core member in the axial direction.

In the above-described embodiment, as shown in FIG. 11 , as the configuration of the connecting portion 74 , both being made of highly flexible fabric and being partially lifted from the supporter main body 10 are adopted. Either one of them may be employed in a modified example. Even with such a configuration, a certain effect can be obtained in that the stay 50 can be easily bent.

In the above embodiment, the stay 50 is composed of the stay main body 54 and the core member 56, both of which are made of resin. Also, an example in which the core member 56 is made of a harder material than the stay main body 54 is shown. In a modified example, the material of the core member 56 may be a metal having a predetermined elasticity. Alternatively, the stay may be made of a single resin member, and the flexible direction may differ between the ends and the central portion with respect to the longitudinal direction of the main body. In this case also, the central portion of the main body has a cross-sectional shape that is narrower and thicker than those at both ends.

In the above-described embodiment, both the stay main body 54 and the core member 56 are configured to change their cross sections in the axial direction of 50 . In a modification, only the core member may have its cross-sectional shape changed in the axial direction. The change in cross-sectional shape in the axial direction may be greater in the core member than in the stator body.

In the above-described embodiment, a configuration in which a plurality of cutouts 60 are arranged at regular intervals on both side surfaces of the stay main body 54 has been exemplified. In a modified example, the intervals between the plurality of notches may be changed as appropriate. The interval may be made smaller toward the center of the stay body, and wider as it moves away from the center. By adjusting the intervals between the plurality of notches, the bending performance of the stay in the width direction can be arbitrarily adjusted.

In the above-described embodiment, a pair of accommodation portions 14 are provided at positions symmetrical with respect to the front surface of the supporter 1, and the stays 50 having the same shape are accommodated in both of them. In a modification, accommodation portions may be provided at asymmetrical positions on the left and right sides of the supporter to accommodate the stays respectively. Further, the stay arranged inside the knee joint and the stay arranged outside the knee joint may have different shapes (external shape and cross-sectional shape).

Alternatively, only one of the left and right sides of the supporter may be provided with an accommodation portion to accommodate the stay. In that case, the accommodating portion may be provided in a portion of the supporter positioned outside the knee joint. Conversely, the accommodating portion may be provided at a portion of the supporter positioned inside the knee joint. Alternatively, accommodation portions may be provided on both the left and right sides of the supporter, and the stay may be accommodated in either one of them. In that case, it is preferable that the accommodating portion has a structure in which the stay can be put in and taken out.

Although one aspect of the supporter 1 is shown in the above embodiment, it goes without saying that the specific structure can be modified as appropriate. For example, the shape, arrangement, number, etc. of the straps may be different from those of the above embodiments. Moreover, a simple tubular structure without a strap may be adopted as the supporter. A structure in which the lower part of the opening for exposing the kneecap is not separated (not opened and closed) may be employed. A structure that does not have an opening for exposing the kneecap may be used.

In the above embodiment, the supporter that protects the knee joint was exemplified. In a modification, a stay configured as a supporter for protecting the elbow and other joints and having similar configuration and characteristics may be applied.
