Description

  The present invention relates to a joint supporter used for protecting a joint part such as a knee or an elbow, and more particularly to a stay provided in the joint supporter for protecting the joint part and soft tissue related to the bending motion thereof.

  When joints such as knees and elbows are injured, a joint supporter is used to relieve the pain associated with the bending movement of these joints and assist the bending movement. The joint supporter is wound so as to cover the joint portion and surrounding muscles, and is fixed by tightening with a fixing belt or a tubular elastic fiber cloth.

  Usually, this type of joint supporter is provided with a stay for reinforcing the joint and muscle so as not to apply a load and maintaining rigidity in the longitudinal direction of the knitted fabric. In Patent Document 1, the stays are made of a resin wire wound in a spiral shape to have appropriate elastic characteristics, and are arranged in two symmetrical directions.

  According to this, even if it compares with the type of the conventional metal wire, it will become inferior in performance and will also become lightweight. Moreover, there is an advantage that the material cost is reduced by using the resin material. However, the use of this stay has the following problems.

  That is, since the stay described in Patent Document 1 forms the resin wire in a spiral shape (coil shape), it not only takes time for production but also increases the processing cost. Moreover, since it is a thin wire, there is a possibility that it will break if used for a long time. Furthermore, rust may be generated due to sweat or washing.

  Also, because the stay is made of metal, it reacts to metal detectors at airports, etc., and it interferes with daily life, and it violates the regulations of sports etc., so it can not be used for sports. There are several points.

  Next, embodiments of the present invention will be described with reference to the drawings, but the present invention is not limited thereto. As shown in FIG. 1, this joint supporter 1 has a supporter body 2 wound so as to cover the joint part, and a pair of fixing belts for fixing the supporter body 2 on the side surface of the supporter body 2. 3 and 3 are provided integrally.

  In this example, the joint supporter 1 will be described by taking the knee joint as an example, but the joint supporter 1 of the present invention may be used not only for the knee joint but also for the elbow joint. Furthermore, it may be used for various joints such as fingers and wrists, and the joint part to be protected is not particularly limited.

  The supporter body 2 is made of a cloth sheet having an appropriate stretchability, and has a sufficient size that can be wound around the knee. In this example, the supporter body 2 is formed in an inverted trapezoidal shape based on ergonomic data in order to hold the thigh from the thigh for the knee joint.

  The supporter body 2 is formed by superimposing a breathable cloth material on the back surface of a stretchable cloth material and integrally sewing it, but the material of the cloth material, the sewing method, etc. are in accordance with the specifications. It may be changed arbitrarily.

  A support hole 21 for exposing and supporting a part of the knee joint is directed to the center of the supporter body 2. In this example, the support hole 21 is a round hole of φ40 mm, and a part of the patella is applied together with the support hole 21.

  On the front side of the supporter body 2 (the front side in the drawing in FIG. 1), there are provided stays 4 and 4 that support the deformation and the muscles associated with the bending motion of the knee joint. Since the stays 4 and 4 have the same shape, only one of them will be described below.

  Referring to FIGS. 2 and 3, the stay 4 is made of a high-elasticity engineering plastic made of polyester elastomer combined with the properties of rubber and plastic, and has appropriate rubber elasticity as well as the rigidity of the plastic.

  The stay 4 is formed in a plate shape having a constant plate thickness (3.0 mm in this example) and an elongated rectangular shape (length 170 mm × width 15 mm). In this example, the stay 4 is chamfered at four corners so as not to damage the fabric when attached to the supporter body 2.

  The stay 4 has a reinforcing portion 41 having a wide plate width at both ends, and these are connected via a bent portion 42 at the center. The bent portion 42 is formed so that the plate width gradually becomes smaller toward the center, and is more easily deformed than the reinforcing portion 41.

  According to this, since the stay 4 is bent in parallel along the plate surface, it is possible to obtain an appropriate bending property at the bent portion 42 while maintaining the shape by the reinforcing portion 41. The stay 4 is integrally attached to both end sides of the supporter body 2 via the backing cloth 22. Furthermore, since the stay 4 is a plate body, it does not move or rotate due to bending.

  At this time, the stays 4 and 4 are arranged such that the center of the bent portion 42 and the center of the support hole 22 are on the same line L. According to this, since the bending of the knee joint and the bending portion 42 of the stay 4 are arranged in the same line, the bending motion can be performed without difficulty. On the contrary, it becomes difficult to bend in parts other than the bending part 42 by the reinforcement part 41, and the load concerning an affected part can be reduced more.

  Referring again to FIG. 1, the fixing belts 3 and 3 are integrally extended from both ends of the supporter body 2. One fixing belt 3 is connected to the lower left portion of the supporter body 2 and is wound around the shin part side. The other fixing belt 3 is connected to the upper right end and fixes the thigh side.

  A hook-and-loop fastener 31 for fixing the fixing belts 3 and 3 in a state of being wound around the supporter body 2 is provided at the tips of the fixing belts 3 and 3. In this example, the hook-and-loop fastener 31 is a hook-side hook-and-loop fastener, and the entire surface of the supporter body 2 is formed with a loop-side hook-and-loop fastener. In the present invention, the specific shapes, configurations, and materials of the fixed belt 3 and the hook-and-loop fastener 31 may be arbitrary.

  As shown in FIGS. 1 and 5, the supporter main body 2 is provided with a temporary fixing belt 5 for temporary fixing when the supporter main body 2 is attached to the leg portion. The temporary fixing belt 5 is an elastic belt having rubber elasticity, and is provided so as to be bridged between the stays 4 and 4. In this example, only one temporary fixing belt 5 is stretched over the upper ends of the stays 4, 4, but they may be arranged on the upper end side and the lower end side, respectively. The number and installation position may be changed according to use.

  One end of the temporary fixing belt 5 is integrally sewn together with a part of the supporter main body 2, in this example, the application cloth 22. The other end of the temporary fixing belt 5 is detachably attached to the supporter main body 2 via an engaging means (not shown) such as a hook-and-loop fastener. In this example, a hook-and-loop means is used as the engaging means, but other than this, as long as the temporary fixing belt 5 such as a button or a hook can be attached and detached, it may be arbitrarily selected according to the specification.

  According to this, as shown in FIG. 5, since both ends of the temporary fixing belt 5 are fixed to the supporter main body 2, the loop portion R for inserting the leg portion is formed. The supporter body 2 can be temporarily fastened to the knee before the fixing belts 3 and 3 are wound by inserting the supporter 2 into the knee.

  In using this joint supporter 1, first, the foot is inserted into the loop portion R of the temporary fixing belt 5 described above, and the supporter body 2 is lifted up to the knee as shown in FIG. A part of the knee N is exposed in the support hole 21.

  Next, with the supporter body 2 temporarily fixed, one fixing belt 3 is wound around the foot and fixed to the supporter body 2 via the hook-and-loop fastener 31. The other fixing belt 3 is also wound in the same manner and fixed with a hook-and-loop fastener 31. By the above, it can mount easily.

  Finally, by inserting a finger between the supporter main body 2 and the leg part and releasing the engagement between the temporary fixing belt 5 and the supporter main body 2, the load on the temporary fixing belt 5 is released. Installation on the legs is completed.

  According to this, since the center of the stay 4 of the joint supporter 1 and the center of the knee joint N are fixed on the same axis L, as shown in FIG. As the joint supporter 1 bends in a state having an appropriate flexibility, the load on the knee can be reduced.

  Further, by using the temporary fixing belt 5, the supporter body 2 can be temporarily fixed before being fixed using the fixing belts 3 and 3, and the joint supporter 1 can be attached to the user's own hands without the assistance of an assistant or the like. It can be attached with.
