  Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings. This is merely an example, and the technical scope of the present invention is not limited to this.

<Overall Configuration of Coating Tool 1>
FIG. 1 is a view showing the overall configuration of a covering device 1 applied to a calf, which is a preferred embodiment of the present invention. FIG. 1 (a) shows a left side view and FIG. 1 (b) shows a rear view. The covering tool 1 has a substantially cylindrical shape having an upper opening 10A and a lower opening 10B at upper and lower ends as openings at both ends, and is made of a material having stretchability and waterproofness. In the present embodiment, since the covering tool 1 is applied to the calf, the diameter of the upper opening 10A is set larger than the diameter of the lower opening 10B, and the diameter gradually decreases from the upper portion to the lower portion. ing. The entire covering device 1 is set to have a diameter smaller than that of the calf so as to be extended during wearing and a predetermined pressure is applied to the calf. Further, a support portion 20 which is a thick portion is formed on the outer surface of the covering tool 1. The support portion 20 is a part of the covering tool 1 and is integrally formed with the covering tool 1.

  As a material for forming the covering tool 1, an elastomer is suitable. Elastomer is a generic term for materials having rubber elasticity. In general, silicone rubber is known as an elastomer having both stretchability and waterproofness. However, the material forming the covering device 1 is not limited to silicone rubber, and any other material may be used as long as it has stretchability and waterproofness.

[Support unit 20]
The support portion 20 is provided to fix and support the gastrocnemius (hifukun) that constitutes the calf. The support portion 20 is a portion made thicker than the other portions constituting the covering tool 1 and has a shape capable of supporting the gastrocnemius muscle. That is, the support portion 20 includes a portion formed at the center in the vertical direction along the center portion of the gastrocnemius muscle and a V-shaped portion formed along the left and right end portions of the gastrocnemius muscle. The portion formed in the middle has a lower end corresponding to the lower ends of the medial gastrocnemius and the lateral gastrocnemius, and is formed up to the upper end, that is, the upper opening 10A. This centrally formed portion maintains the shape of the muscle and prevents loss of muscle pumping effects. The V-shaped portion formed along the left and right ends comprises a portion along the inner end of the medial gastrocnemius muscle and a region along the outer end of the lateral gastrocnemius muscle. The V-shaped portion can support the gastrocnemius muscle from both ends and stabilize the gastrocnemius muscle.

  In the present embodiment, the thickness of the support portion 20 is the same without depending on the place. Further, the portion formed in the center of the support portion 20 and the portion formed in a V-shape on the left and right are formed so that the width gradually widens from the lower portion to the upper portion. By configuring in this way, it is possible to support the gastrocnemius muscle more stably stably, and to prevent retention of fluid including lymph by maintaining the function of the muscle.

[Waterproof part 30]
FIG. 2: is AA sectional drawing of the coating tool 1 shown in FIG.1 (b). In the upper opening 10A and the lower opening 10B of the covering tool 1, waterproof portions 30A, 30B are formed on the inner surfaces thereof to prevent water from entering the inside of the covering tool 1 during wearing. In the present embodiment, the waterproof portions 30A, 30B are formed of three ridges formed in the circumferential direction on the inner peripheral surface of the covering tool 1.

  The waterproof portions 30A and 30B in the present embodiment are respectively formed of three convex streaks having a substantially rectangular cross section provided in the circumferential direction on the inner peripheral surfaces of the upper opening 10A and the lower opening 10B. The radial height of the ridges is highest at the outermost ridge, and the heights of the two inner ridges are set lower than the height of the outermost ridge. In this case, the heights of the inner two ridges are set to be the same, but the outermost ridge is the highest and the innermost ridge is the lowest, and the middle ridge is The parts can also be configured to have an intermediate height.

[Rib 40]
In the present embodiment, the inner peripheral surface of the covering tool 1 is provided with a rib 40 which is formed in a circumferential direction and has a substantially square convex ridge portion in cross section. The rib 40 is provided to fix and maintain the gastrocnemius muscle, and is provided at a position corresponding to the lower end of the gastrocnemius muscle. That is, as shown in FIG. 1 and FIG. 2, when the support portion 20 is provided, the rib 40 is provided at the same position as the start point of the support portion 20. Thus, by using the support portion 20 and the rib 40 in combination, it is possible to maintain the shape of the gastrocnemius muscle and to further prevent the loss of the pumping effect by the muscle. The rib 40 does not necessarily have to be used in combination with the support portion 20, and the rib 40 can be provided with the function of holding the gastrocnemius with only the rib 40 without providing the support portion 20.

〔how to use〕
In order to wear the covering tool 1 formed in this way, first, a toe is inserted from the upper opening 10A. Then, the region close to the ankle is taken out from the lower opening 10B, and the upper opening 10A is pulled upward so that the support portion 20 is located in the vicinity of the gastrocnemius muscle of the calf, and the wearing is completed. At this time, since the entire covering tool 1 is formed to have a diameter smaller than that of the calf, it is necessary to put a finger from the upper opening 10A and pull it upward while spreading the covering tool 1. Since the waterproof part 30A which consists of a convex ridge of a book is formed, the upper opening 10A can be smoothly pulled up by putting a finger on these convex ridges.

  During wear, pressure is applied to the gastrocnemius constituting the calf in order to closely press the calf in a stretched state of the fabric forming the covering device 1. As a result, it is possible to obtain the effect of preventing lymph from staying in the vicinity of the calf, and it is possible to prevent edema. In addition, since the covering device 1 is provided with the support portion 20 for fixing the gastrocnemius and holding the muscle, the pumping effect by the muscle can be maintained without breaking the shape of the gastrocnemius, and further prevention of edema You can get the effect of Furthermore, since a rib 40 is formed at a position corresponding to the lower end of the gastrocnemius muscle inside the covering tool 1, the shape of the gastrocnemius muscle is maintained together with the effect by the support portion 20, and the pump effect by the muscle is further enhanced. It can be further improved.

  Moreover, although you may wear the covering tool 1 on bare skin, the effect can be improved by applying the oil which has a tightening effect and a massage effect on a skin, and wearing the covering tool 1 on it. That is, in addition to the pressurization effect and the gastrocnemius muscle support effect of the covering tool 1, the further edema prevention effect can be obtained by adding the effect by oil. Also, by applying oil, the friction between the skin and the fabric is eliminated, and smooth wear becomes possible. As oil to be applied to the skin, in addition to those having a tightening effect and a massage effect, so-called aroma oils with a scent can be applied.

  Moreover, the effect of edema prevention can be expected by bathing in the state which wore the covering tool 1 in this embodiment. That is, since the covering tool 1 in the embodiment is made of an elastomer such as thin silicone rubber, the thermal conductivity is high, and if bathing while being worn, a higher warm bath effect can be obtained. As a result, the blood flow and the flow of lymph are promoted and the further effect of pushing up the lymph which tends to stay in the lower body is obtained, and the synergistic effect of the pressure effect and the warm bath effect by the covering device 1 itself further prevents edema You can get the effect.

  And since waterproofing parts 30A and 30B are provided in upper opening 10A and lower opening 10B in covering tool 1 in this embodiment, it is possible that hot water stretched in a bath infiltrates between covering tool 1 and the skin. It can be prevented. That is, three convex streaks are formed in each of the waterproof portions 30A and 30B, and these convex streaks bite into and adhere to the skin to prevent the entry of water.

  At this time, since the ridges have a substantially rectangular cross-sectional shape, it is possible to secure a wide area where the ridges and the skin are in close contact, and it is possible to reliably prevent the entry of water.

  In addition, since the height of the ridges in the radial direction is set so that the outermost ridges are higher than the two ridges on the inner side, infiltration of water at the end of the covering tool 1 can be reliably achieved. It has a function to prevent. In addition, since the height of the ridges at the outermost side is the highest, the covering tool 1 can be pulled up without distortion when worn. That is, since the covering tool 1 in the present embodiment is stretchable as a whole and has a diameter smaller than that of the calf, if the heights of the three ridges are equal, the finger is inserted from the upper opening 10A. When the covering tool 1 is spread and pulled upward, there is a possibility that the finger may not be well scratched, and the shape after wearing may be distorted. In such a case, the waterproof portions 30A and 30B do not function, and water infiltrates. In this embodiment, since the height in the radial direction of the outermost ridge is set higher than the two inner ridges, it is possible to easily put a finger on the outermost ridge. ing. Therefore, the coating tool 1 can be pulled up without causing distortion, and the effects of the waterproof portions 30A and 30B can be sufficiently exhibited.

  Due to the function of the waterproof portions 30A, 30B, the covering device 1 in this embodiment is used not only for the purpose of edema prevention but also as a waterproof cover for preventing wounds and the like from getting wet during bathing. Can. In this case, even if water intrudes from the upper opening 10A and / or the lower opening 10B, the covering tool 1 is formed to have a small diameter so that the entire covering device 1 adheres to the calf, preventing the water from reaching the affected area. Can. Therefore, it becomes possible to take a bath with ease by attaching the covering tool 1 in the present embodiment to the affected part.

  As mentioned above, although one form for implementing this invention was demonstrated, below, another embodiment is described.

  FIG. 3 shows the structure of the waterproof portion 30A of various types. A desired function can be obtained by the radial height and shape of the ridges. The waterproof portion 30B in the lower opening 10B has the same structure as the waterproof portion 30A in the upper opening 10A except that the upper and lower portions are reversed.

  The waterproof part 30A shown in FIG. 3A has the same structure as that shown in FIG. That is, the waterproof portion 30A is composed of three convex streaks 31A, 32A, 33A having a substantially rectangular cross section provided in the circumferential direction on the inner peripheral surface of the upper opening 10A. The height of the ridges in the radial direction is highest at the outermost ridge 31A, and the height of the two inner ridges 32A and 33A is set lower than the height of the outermost ridge 31A. It is done. In this case, although the heights of the two inner ridges 32A and 33A are set to be the same, the outermost ridge 31A is the highest, and the inner ridge 33A is the lowest. The convex ridge 32A in the middle may have an intermediate height.

  In this case, as described above, since the outermost ridge 31A is set higher than the two ridges 32A and 33A on the inner side, entry of water is reliably prevented at the end of the covering tool 1 Have a function to Moreover, since it is a structure which is easy to put a finger on convex ridge 31A in the outermost side, covering tool 1 can be pulled up without distortion at the time of wearing.

  Waterproof part 30A shown in FIG.3 (b) shows the modification of waterproof part 30A shown to Fig.3 (a). That is, the heights of the outermost ridge 31A and the middle ridge 32A are the same as those of the waterproof portion 30A shown in FIG. 3A, but the height of the inner ridge 33A is the largest. The height is set to be the same as the height of the outer ridges 31A.

  In this case, since the height of the innermost ridge 33A is set to be as high as the height of the outermost ridge 31A, it is easy to put a finger on the innermost ridge 33A, which is more reliable. The covering tool 1 can be pulled up to be worn without distortion. Further, even if water infiltrates through the ridges 31A and 32A, the ridge 33A can reliably prevent the water from entering.

  Waterproof part 30A shown in FIG.3 (c) shows the modification of waterproof part 30A shown in FIG.3 (b) further. That is, the ridges 34A are further provided inside the ridges 33A, and the height of the ridges 34A is set lower than the ridges 31A and 33A, similarly to the height of the ridges 32A.

  In this case, the effect of preventing the entry of water can be improved by the action of the four ridges. In addition, since the height of the innermost ridge 34A is set low, water penetration is prevented while maintaining a comfortable wearing ability that can withstand long-time wearing without giving an excessive sense of pressure to the calves. The effect can be improved.

  Waterproof part 30A shown in FIG.3 (d) shows the modification of waterproof part 30A further shown in FIG.3 (c). That is, the height of the innermost ridge 34A is set high similarly to the outermost ridge 31A, and the height of the ridge 33A is the same as the height of the ridge 32A in the ridge 31A. It is set lower than the height.

  In this case, the effect of preventing the entry of water can be improved by the action of the four ridges. In addition, since the height of the innermost ridge 34A is set to be the same as the height of the outermost ridge 31A, it is easy to put a finger on the innermost ridge 34A, and the covering is more reliably performed. The tool 1 can be pulled up to be worn without distortion. Further, even if water infiltrates through the ridges 31A, 32A, and 33A, the ridge 34A can reliably prevent the water from entering.

  The waterproof portion 30A shown in FIG. 3 (e) and FIG. 3 (f) is an example in which the shape of the ridge portion is changed. That is, although the cross-sectional shape of the ridges 31A to 34A of the waterproof portion 30A shown in FIG. 3A to FIG. 3D is substantially square, FIG. The cross section of the ridges 31A to 33A of the waterproof portion 30A shown has a mountain-like shape in which the width of the base end is wide and the width of the tip is narrow. FIG. 3E shows an example in which the cross sections of the ridges 31A to 33A are linearly reduced, and FIG. 3F shows an example in which the cross sections of the ridges 31A to 33A are curvilinearly reduced.

  If the cross-sectional shape of the ridge portion is a mountain-like shape with a wide base end portion and a narrow tip portion width, the ridge portion will not fall when worn. That is, since the covering tool 1 is elastic and has a diameter smaller than that of the calf, it can be pulled upward while being in close contact with the shin and the calf when worn. At this time, as shown in FIG. 3A to FIG. 3D, if the cross-sectional shape of the ridge portion is substantially square, there is a possibility that the ridge portion may fall downward. When the ridges fall downward, the force with which the ridges are pressed against the calves weakens, so the waterproof function as a waterproof part can not be exhibited. In this embodiment, since the cross-sectional shape of the ridge portion is a mountain shape having a wide base end portion and a narrow tip end portion, the ridge portion does not fall downward when worn, and the waterproof effect is stably achieved. Can be demonstrated.

  In the example shown in FIG. 3E, the cross sections of the ridges 31A to 33A are linearly reduced and have a substantially triangular cross section. In this case, it is possible to prevent the convex ridge portion from falling and failing to exhibit the waterproof function as described above, and also to exhibit a reliable waterproof effect by the convex ridge portion. That is, since the cross sections of the ridges 31A to 33A have a substantially triangular shape, it is easy to bite into the skin, and it is possible to more reliably prevent water from entering.

  In the example shown in FIG. 3 (f), the cross sections of the ridges 31A to 33A are curvilinearly reduced, and the cross-sectional shape at the tip has a substantially semicircular or parabolic shape. In this case, it is possible to prevent the projection from falling and failing to exhibit the waterproof function as described above, and to obtain more comfortable wearing. That is, since the tip of the ridge is a smooth curved surface, there is little stimulus given to the skin, and the ridge can fall and exhibit a waterproof function while maintaining a comfortable wearability that can withstand long-time wearing It can prevent losing.

  The mountain-like shapes as shown in FIG. 3 (e) and FIG. 3 (f) can be used in combination with the pattern of the ridges shown in FIGS. 3 (a) to 3 (d). Alternatively, it is also possible to make the heights of the plurality of convex streaks the same, and to make only the cross-sectional shape into a mountain shape as shown in FIGS. 3 (e) and 3 (f).

[Thickness 50]
In the example shown in FIGS. 1 to 3, although the ridge portion is provided on the inner peripheral surface near the upper opening 10A as the structure of the waterproof portion 30A, the outer peripheral surface near the upper opening 10A as shown in FIG. It is good also as composition which gives thick part 50 to. That is, by forming the outer peripheral surface of the region where the ridges 31A to 34A are provided to be thicker than the portion that constitutes the entire covering tool 1, the upper opening 10A can be made less susceptible to deformation. More powerfully, it is possible to prevent the entry of water from the outside.

  Such thick portions 50 on the outer peripheral surface in the vicinity of the upper opening 10A may be provided in combination with the ridges 31A to 34A on the inner surface, or the ridges 31A to 34A are not provided but are used alone It is also good. In the case where the thick portion 50 is provided alone without providing the ridges 31A to 34A, the structure is further simplified, so that the covering tool 1 can maintain the waterproof function while suppressing the manufacturing cost. It can be done.

  Further, in the present embodiment, the thick portion 50 is provided only in the outer peripheral portion of the upper opening 10A, but the thick portion 50 may be provided in the outer peripheral portion of the lower opening 10B.

  Here, as shown in FIG. 4, in the case where the thick portion 50 is provided on the outer peripheral surface in the vicinity of the upper opening 10A, the support portion 20 and the thick portion 50 have the same thickness. And the thick portion 50 may be connected without any step.

  In the above embodiment, the thickness of the support portion 20 is configured to have the same thickness both in the portion formed in the center in the vertical direction and in the portion formed in the V shape in the left and right However, as shown in FIG. 5, it is also possible to adopt a configuration in which the thickness gradually increases from the bottom to the top. By configuring in this way, the support force can be configured to gradually increase upward, so that a covering device having a function of effectively pushing up the water containing lymph fluid by using the support force gradient. It can be done.

  In the above embodiment, an example is shown in which the covering device 1 is configured to be worn on a calf, but the present invention is not limited to a calf, but may be a knee, a thigh, an abdomen, an upper arm, an elbow, a wrist, etc. It may be attached to a part of

  As mentioned above, although embodiment of this invention was described, this invention is not limited to these embodiment mentioned above. Further, the effects described in the embodiments of the present invention only list the most preferable effects resulting from the present invention, and the effects according to the present invention are limited to those described in the embodiments of the present invention is not.

In the modern society, an increasing number of people suffer from swelling of the calf. Edema is caused by the retention of fluid, including lymph, in various parts of the body. The retention of water is a phenomenon that occurs notably when, for example, the same posture is continued for a long time, and is particularly likely to occur in the lower body. Here, as clothing for preventing the retention of water in calves, there is a sock that exerts pressure on the calves during wear and pushes back water containing lymph fluid to the upper part of the body (see JP-A-3-70558). . In addition, a covering device has been developed which can provide similar effects to edema of the thigh and edema of the upper arm and the like.

[Summary of the invention]
[Problems to be solved by the invention]
In general, the above-mentioned socks and covering tools are formed by knitting yarns made of synthetic fibers, and have the merit of being stretchable and easy to attach and detach.

  However, since it is a synthetic fiber, the coefficient of friction with the skin is not high, and the sock tends to be displaced from the application site regardless of wearing, and there is a problem that an expected effect may be difficult to obtain.

  Moreover, although it has elasticity, since it is made of a synthetic fiber, it is weak to wet, and in particular, it is not suitable for use such as bathing while wearing.

  An object of the present invention is, in view of these problems, to provide a covering device which has no fear of being displaced during wearing, provides a high edematous preventing effect, and can be bathed while being worn.

[Means for Solving the Problems]
The present invention provides the following solutions.

  The invention according to the first aspect is a covering device worn on a calf, which is formed in a tubular shape having a diameter smaller than that of a calf by a material having stretchability and waterproofness, and the stretchability when worn on a calf Provided is a covering device which is elastic enough to apply a predetermined pressure, has openings for inserting calves at both ends, and forms a thick support portion at a position corresponding to gastrocnemius when worn. .

  According to the invention of the first aspect, the elastic and waterproof material is formed into a tubular shape having a diameter smaller than that of the calf, and is configured to apply a predetermined pressure when mounted on the calf. Therefore, it is possible to provide a covering device which can apply pressure stably to the calf without being displaced during wearing, and can surely obtain an edema prevention effect. Further, since the thick support portion is formed at the position corresponding to the gastrocnemius, the pump effect by the muscle can be maintained without breaking the shape of the gastrocnemius, and it is possible to obtain a further effect of preventing edema. Can be provided. Furthermore, since the waterproof material is formed so as to be in close contact with the calves, a synergetic effect of the pressurization effect and the warm bath effect can be obtained by taking a bath while wearing, and a further effect of preventing edema can be obtained. Possible coating tools can be provided.
