FIG. 1 is a schematic perspective view of a joint protector 1. FIG. 2 is a schematic cross-sectional view of the pad 10 shown in FIG. 1 as viewed from the left side.

  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 Joint Protective Device 1>
FIG. 1 is a schematic perspective view of a joint protector 1 according to a preferred first embodiment of the present invention. The joint protector 1 comprises a pad 10 and a fixing band 20 for fixing the pad 10 to the joint.

[Pad 10]
FIG. 2 is a schematic cross-sectional view of the pad 10 shown in FIG. 1 as viewed from the left side. The pad 10 is attached to a joint such as a knee, an elbow and a wrist, and is for absorbing an impact applied to a bone constituting the joint, and has two surfaces, ie, a concave inner surface 10A that abuts on a user's bone. Hereinafter, it is also referred to simply as "inner surface 10A" and an outer surface 10B facing the bone on the opposite side. In addition, the pad 10 as used in this specification refers to the member provided with the shape-retaining property of a grade which has a concave-shaped inner surface, when making it stand and it does not depend on the below-mentioned fixing band etc. Like the polyurethane resin sheet of Patent Document 1, although it is a flat inner surface when made to stand, it does not include a non-shape retaining member that only has a concave inner surface by the force of the tubular supporter. As a result, the average thickness of the pad 10 is not particularly limited, but is 5 mm or more, specifically 1 cm or more (the upper limit is not limited, but may be 10 cm or less, for example).

  The pad 10 is composed of multiple layers of materials bonded together. As shown in FIG. 2, the pad 10 has a foam material layer 12 interposed between two fabric layers 11 defining an inner surface 10A and an outer surface 10B.

  The foam material layer 12 is a layer of a material that absorbs an impact applied to a joint, and is preferably formed of a silicone-based resin, but if it can absorb an impact, alpha gel, polyurethane, etc. Other materials may be used. Also, the foam material layer 12 may be a sheet-like solid layer joined to the two-layer fabric layer 11, but by a liquid or gel-like material injected between the two-layer fabric layer 11 It may be a formed layer. Further, although the foam material layer 12 is a layer formed between the two fabric layers 11, the pad 10 may be formed of a single layer of the foam material layer 12.

  In this embodiment, since the foam material layer 12 is formed of a material having excellent impact resistance, even if a large impact is applied to the joint, the impact can be absorbed and the joint can be protected. In addition, since the foam material made of the shock absorbing material has flexibility, it has a high ability to follow the movement of the joint, and it firmly fits the joint in any posture and posture, The joints can be reliably protected from impact.

  By the way, in this embodiment, the pad 10 which comprises the protective tool 1 is formed with a transparent or semi-transparent material as a whole. Thereby, anyone can use the joint protector 1 without worrying about matching between the color of the background and the color of the pad.

  That is, when wearing a protector in the state where a joint was exposed, such as at the time of sports or swimming, if the color of the protector is different from the color of the skin, the user may feel discomfort. In the present embodiment, since the pad 10 of the protective device 1 is made of a transparent or translucent material, the user can use it without feeling the difference from the color of the background, so anyone can wear it casually. Can provide joint protection. However, the pad is not limited to this, and the pad may be made of an opaque material, and may be colored including pigments such as skin color, yellow and black.

  In the present embodiment, on the inner surface 10A of the pad 10, a pressure-sensitive adhesive layer 13 for suppressing displacement with a joint is formed. The pressure-sensitive adhesive layer 13 has an adhesion to the pad 10 that is greater than the adhesion to the skin of the user, and a substance having pressure-sensitive adhesion is applied or affixed to the inner surface 10A of the pad 10 It is formed.

  The pressure sensitive adhesive layer 13 generates the desired adhesion between the inner surface 10A of the pad 10 and the skin, enabling the pad 10 to be supported in the desired position of the joint. By the function of the pressure-sensitive adhesive layer 13, it is possible to prevent the joint and the protective device 1 from being displaced even during intense exercise. The amount and type of the pressure-sensitive adhesive substance used for the pressure-sensitive adhesive layer 13 can be variously changed, and the position and size of application or sticking to the inner surface 10A of the pad 10 can also be variously changed. . The amount, type, and position of the pressure-sensitive adhesive substance are determined by various factors such as the place of use, the purpose (sports or daily life), and the size and preference of the user's body. Here, it is important that the pressure sensitive adhesive layer 13 be integrated into the pad 10, so that the movement of the joint can be followed.

  The pressure sensitive adhesive layer 13 is preferably a repeatable pressure sensitive adhesive permanently attached to the inner surface 10A of the pad 10 or formed as the inner surface 10A. Pressure sensitive adhesive layer 13 may also be applied to the inside of pad 10 by various methods such as extrusion coating, hot melt, spray coating, die coating, or any other known method for applying a pressure sensitive adhesive to a substrate. It can be applied to the surface 10A.

  The pressure-sensitive adhesive layer 13 can withstand a user's intense movement or a large impact without causing a slip, and does not deteriorate the adhesive property even when exposed to water or sweat. Moreover, even if dirt adheres to the pressure sensitive adhesive layer 13, the adhesive property can be recovered by washing with water or a soap.

  In the present embodiment, the pressure-sensitive adhesive layer 13 is applied or affixed to the fabric layer 11 which is the inner surface 10A of the pad 10, but in consideration of the adhesion of the pressure-sensitive adhesive to the pad 10 , Forming a layer of thermoplastic film material and a layer of impermeable non-woven fabric on the outside of the fabric layer 11, and applying a pressure sensitive adhesive to the surface of the layer of thermoplastic film material and the layer of non-permeable non-woven fabric It may be

  The pad 10 may optionally contain a metal (titanium, silver, gold, etc.) or a chemical component (aloe extract, vegetable carbon fiber, perfume, etc.). For example, titanium can be expected to alleviate pain and spasm, silver can be antibacterial, aloe extract can suppress rash on the skin surface contacting pad 10, and vegetable carbon fiber can be expected to impart a thermal effect.

[Fixing band 20]
Return to FIG. In the present embodiment, the fixing band 20 for fixing the pad 10 to the joint is connected to the inner surface 10A of the pad 10 via the connecting parts 20A and 20B at both ends of the fixing band 20. The fixing band 20 is preferably made of a resin having appropriate stretchability, but the invention is not limited thereto, and the length may be adjusted. The connection area in the pad 10 may be appropriately designed in accordance with the material and structure of the fixed band to be used.

  Well-known means, such as a hook member and a loop member, can be applied as the connecting portions 20A and 20B. In addition, it is preferable that a known means capable of adjusting the length of the fixing band 20 be applied to the fixing band 20. As a result, removal from the pad 10 is easy, and anyone can use it regardless of the size of the body, and a stable and easy-to-use fixing band 20 can be obtained.

  The pad 10 can be firmly fixed to the joint by the fixing band 20 thus formed. That is, when the protector 1 is worn on a joint, the pad 10 is applied to the bone constituting the joint, and the fixation band 20 is passed through the back of the joint. At this time, since the fixing band 20 is formed of a stretchable material, the elastic tension of the fixing band 20 enables the pad 10 to be firmly fixed to the joint.

  Further, in the present embodiment, the connecting portions 20A and 20B, to which the fixing band 20 and the pad 10 are connected, are formed so as to be located at positions corresponding to the left and right end portions of bones constituting a joint, respectively. . Therefore, the bone constituting the joint can be stabilized by elastic tension, and the fixing band 20 can be prevented from being displaced from the joint with the movement of the joint.

  That is, in the present embodiment, since the fixing band 20 having elasticity is connected to the pad 10 at a location corresponding to the left and right ends of the bone constituting the joint, it is always determined starting from the left and right ends of the bone. Thus, even if the joint is moved significantly, the joint with the fixing band 20 does not shift. Therefore, it becomes possible to stabilize the said bone and to continue the stable wearing without the protector 1 itself being displaced from the joint.

  In the present embodiment, a separate member such as a hook portion is used as the connecting portions 20A and 20B, but a structure in which the end portion of the fixing band 20 is embedded in the pad 10 without using a hook member or the like It does not matter. Alternatively, the fixing band 20 and the pad 10 may be integrally formed of the same material.

  In the present embodiment, in the inner surface 10A of the pad 10, in the region surrounding the bone forming the joint, the convex portions are formed on both sides not in the joint movable direction, and the convex portions are not on both sides in the joint movable direction. Preferably it is a formation. By providing the convex portion in the above-described region, it is possible to completely protect the joint while securing the movable range of the joint. For example, in the case of the protective tool 1 attached to the knee joint, the patella is not restricted by restricting the movement of the knee joint by forming the convex portions in the area which abuts the left and right sides of the patella and excludes the top and bottom. Can be reliably protected.

  Further, in the fixing band 20, the cylindrical impact absorbing member can be formed to pass through the back of the joint.

  Due to the flexibility of the silicone resin, the cylindrical impact-absorbing member thus formed can be used, for example, when standing up, in religious ceremonies, etc., in upright postures, worships, sittings, etc. When repeating a plurality of types of postures, it is possible to reduce the great burden on the joints.

  In a second embodiment, the pad may have neither a fixed band nor a connection area. However, the pad in this case has on its inner surface a pressure sensitive adhesive layer bonded with an adhesive strength greater than that of the user's skin. Thereby, even if there is a large movement while wearing, it is possible to reliably prevent the deviation from the joint. The other configuration is the same as the above-described embodiment, and thus the description thereof is omitted.

  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.
