Abstract

PROBLEM TO BE SOLVED: To provide a knee supporter that is prevented from slipping down or slipping up when worn and used, without special use of a separate fixing member such as a side stay and a strap.SOLUTION: A knee supporter is characterized as follows: a part of a tubular supporter body which covers a front side of a knee joint is formed as a concavely-curved surface toward a kneepan area from its upper and lower ends; and a part of the supporter body which covers a rear side of the knee joint is formed as a flat surface in the backside area part of the kneepan while forming a concavely-curved surface from its upper and lower ends.

Description

  The present invention relates to a knee supporter, and more particularly to a knee supporter that does not slide down or slide up when worn.

In general, knee supporters of a simple cylindrical type (for example, see Patent Document 1) and a "<" shape that protrudes and bends to the front side (for example, see Patent Document 2) are widely used.
However, when such a conventional knee supporter is used while being mounted on the knee, it is said that the knee will fall above the patella and the knee below the patella due to repeated knee flexion and extension. There was a problem.
Therefore, in the past, when trying to prevent such slipping or sliding, it was the actual situation that separate fixing members such as side stays and straps had to be used.

  The present invention has been made in view of the above-described conventional problems and actual situations, and does not slide down or rise during use without using a separate fixing member such as a special side stay or strap. The challenge is to provide knee supporters.

  As a result of intensive research to solve the above-mentioned problems, the present inventor unexpectedly bent the front side covering portion of the knee supporter in a concave manner, contrary to the conventional "<"-shaped supporter. The present invention has been completed by finding that extremely good results can be obtained by making the rear surface covering portion concave from both the upper and lower ends and making it flat in the back region of the patella.

  Further, the present inventor has the effect of preventing the sliding and rising when the upper opening edge of the knee supporter is inclined upward from the front side to the rear side and the lower opening edge is inclined downward from the front side to the rear side. Has been found to be improved, and the present invention has been completed.

  That is, according to the present invention, the front side covering portion of the knee joint of the cylindrical supporter body has a concave curved surface from the upper and lower end portions toward the patella region, and the rear side covering portion of the supporter main body has the upper and lower end portions. The above-mentioned problem is solved by a knee supporter characterized in that a concave curved surface is formed from the portion and a flat surface is formed in the back side region of the patella.

  Further, the present invention is configured to incline and incline the upper opening edge of the cylindrical supporter body from the front surface side covering portion toward the rear surface side covering portion, and to lower the lower opening edge portion from the front surface side covering portion to the rear surface side covering portion. The above-mentioned problem is solved by a knee supporter characterized by being inclined downward.

  If the knee supporter of the present invention is used, it is possible to prevent the sliding or the sliding from occurring during use without using a separate fixing member such as a special side stay or a strap.

  Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 10 denotes a cylindrical support body that is open at the top and bottom, and the entire body has elasticity in the vertical and horizontal directions. The front side covering portion 11 of the knee joint is compared with the horizontal direction when worn. In addition, the longitudinal direction is more easily stretchable (low elasticity), and the rear surface side covering portion 12 is more easily stretched (lower elasticity) in the lateral direction than the longitudinal direction when worn. It is particularly desirable because it can cope with bending and stretching of the film while maintaining adhesion.
The front side covering portion 11 of the knee joint has a concave curved surface from the upper and lower ends toward the patella region. The distance L to the deepest portion of the concave curved surface is preferably about 10 to 25 mm, particularly about 15 to 20 mm, from the viewpoint of obtaining a sliding-off or sliding-up preventing action.
Further, the rear surface side covering portion 12 of the knee joint forms a concave surface 12a from both upper and lower end portions toward the back side region portion of the patella, and has a flat surface 12b in the back side region portion of the patella. The distance M to the deepest portion of the concave curved surface, that is, the flat surface 12b, is preferably 5 to 20 mm, and particularly preferably 5 to 10 mm, in order to obtain an effect of preventing the sliding and the rising. Further, the length N of the flat surface 12b is preferably 40 to 60 mm, and more preferably 45 to 55 mm, in order to obtain a sliding-off and sliding-up preventing action.

  The upper opening edge 13 of the supporter main body 10 is inclined upward from the front surface side covering portion 11 toward the rear surface side covering portion 12, and the lower opening edge portion 14 extends from the front surface side covering portion 11 to the rear surface side covering portion 12. 12 is inclined downward. Ascending inclination angle α is 10 to 30 °, particularly 15 to 20 °, and angle β with respect to falling inclination is 5 to 20 °, particularly 5 to 15 °. It is preferable for obtaining the action.

  13a is an upper edge taping portion, which is stretchable in the circumferential direction (low elasticity), but is not stretchable in the axial direction (high elasticity). It is fixed. Reference numeral 14a denotes a lower edge taping portion which is fixedly attached to the lower opening edge portion 14 by the same fabric and means as the upper edge taping portion 13a. By attaching and fixing the upper edge taping portion 13a and the lower edge taping portion 14a, axial expansion and contraction is hindered at the upper and lower opening edge portions, and the fixing holding force to the leg portions is improved. The rise can be prevented.

  Such a knee supporter of the present invention can be obtained by connecting the two parts of the front side covering part 11 and the rear side covering part 12 having elasticity as described above by means of stitching or the like to form a cylinder. In particular, when the four parts of the side part 10a, the front part 10b, the side part 10c, and the rear part 10d having a stretchable shape as shown in FIG. Knee supporter with excellent adhesion can be obtained. In this case, as described above, it is particularly desirable that the front part 10b has elasticity in the vertical direction and the rear part 10d has elasticity in the horizontal direction.

  Next, the operation of the above knee supporter of the present invention will be described.

  When the knee is extended (standing body), when viewed from the side, it is not a vertical columnar shape, but on the front side, it is concavely curved by about 15 mm from the patella to the neck surface, and from the top of the patella to the thigh. A dent is formed between the bones, and on the other hand, the back side of the patella is recessed about 15 mm from the position of the triceps surae (calf) toward the front side. As the knee bends and stretches, the thigh muscles and triceps surae repetitively contract the muscles vertically and horizontally above and below the patella. Incidentally, the circumferences of the thigh muscles and triceps surae muscles are the thinnest when extended, and the thickest when bent at 90 °.

  When a conventional simple cylindrical type knee supporter is attached to such a knee, as shown in FIG. 4, when the knee is bent, the front side covering portion of the knee joint having elasticity is in the direction from the patella to the upper and lower ends. (The arrow X in FIG. 4) extends, and the rear-side covering portion that also has elasticity extends from the upper and lower ends toward the center of the back of the knee (arrow P in FIG. 4). In this state, the restoring force of the front side covering portion acts in the patella direction (arrow Y in FIG. 4) from both the upper and lower ends. The acting direction of the restoring force is the extension direction of the rear side covering portion (see FIG. 4 is coincident with the arrow P).

  Thus, when the knee is bent and extended, the front side covering portion is contracted and restored from the upper and lower ends in the direction of the patella (arrow Y in FIG. 4), and the rear side covering portion is Although it shrinks and restores in the direction of the upper and lower ends from the back center part (arrow Q in FIG. 4), since the extension degree of the front side covering part is larger than the extension degree of the rear side covering part, the restoring force of the front side covering part ( In FIG. 4, the arrow Y) is stronger than the restoring force of the rear surface side covering portion (arrow Q in FIG. 4).

  For this reason, the supporter slides from the upper and lower ends toward the patella by repeating the contraction action of the front side covering part and the rear side covering part accompanying the bending and stretching of the knee, and the simple cylindrical type supporter is extended to the knee. It does not correspond to the shape of the time, and in combination with the fact that the degree of close contact with the skin surface tends to decrease overall, the attached supporter falls off above the patella and falls below the patella There was a rise.

  In addition, since the conventional “K” -shaped knee supporter is already in the form shown in FIG. 4 before wearing, the stretching force and thus the restoring force are alleviated when the knee is bent. In contrast to the extension, the restoring force from the upper and lower ends to the patella direction (arrow Y in FIG. 4) and the center of the knee back (arrow P in FIG. 4) is strengthened. As a result of the significant decrease in the degree of adhesion, as with the simple cylindrical type, the slipping also occurred above the patella and the slipping below the patella.

  In contrast, the knee supporter of the present invention, as shown in FIG. 1, has a front-side covering portion 11 and a rear-side covering portion 12 that are concavely curved surfaces. Besides, strong adhesion to the skin surface can be obtained even during the extension. Thus, when the knee is bent in this wearing state, as shown in FIG. 3, the restoring force of the front surface side covering portion 11 is from the patella to the knee back direction (arrow Z in FIG. 3) by the concave curved surface portion. Therefore, the restoring force from the upper and lower ends to the patella direction (arrow Y in FIG. 3) is reduced. In addition, since the rear surface side covering portion 12 is also a concave curved surface 12a, when the knee is bent, the rear surface side covering portion 12 extends from the upper and lower end portions toward the center of the back of the knee (arrow P in FIG. 3). The stretching action is alleviated and the back side region of the patella is the flat surface 12b following the concave curved surface 12a. In the middle, there is almost no extension action to the arrow P).

  Therefore, if the knee supporter of the present invention is used, the action from the upper and lower ends of the supporter to the patella direction (arrow Y in FIG. 3) is diminished, combined with a strong adhesion with the skin surface, Without using a separate member such as a special side stay or a strap, it is possible to prevent slipping above the patella and slipping below the patella.

  In addition, the conventional simple cylindrical type knee supporter has horizontal edges that are parallel to the upper and lower opening edges. Therefore, when the knee is bent after wearing, as shown in FIG. Since the rear side upper opening edge is lower than the upper part, the restoring force of the front side covering part in the patella direction (arrow Y in FIG. 4) slips down in the patella direction corresponding to the lower position. Since the rear side lower opening edge is higher than the front side lower opening edge, the higher force is obtained by the restoring force of the front side covering part in the patella direction (arrow Y in FIG. 4). In accordance with the position, the patella is likely to slide up.

On the other hand, as shown in FIG. 1, the knee supporter of the present invention has a higher position on the rear upper opening edge than the front upper opening edge. As a result of the rear side upper opening edge being higher than or equal to the front side upper opening edge, the rear side upper opening edge is in the patella direction of the front side covering part (arrow Y in FIG. 3). ) Acts as a stopper for restoring force.
In addition, since the rear lower opening edge is lower than the front lower opening edge, even if the knee is bent, the rear upper opening edge is lower than the front lower opening edge. As a result of the same position, the rear lower opening edge functions as a stopper for restoring force of the front covering portion in the patella direction (arrow Y in FIG. 3).

  Therefore, if the above-described knee supporter of the present invention is mounted and used, the supporter can be more reliably prevented from sliding down or sliding up.
