Description

  The present invention relates to a cardio-protective shirt for a ball game worn at the time of a ball game for the purpose of suppressing the onset of cardiac concussion, and a heart-protection pad used therefor.

  In recent years, attention has been paid to the symptom of cardiac concussion that leads to cardiac arrest due to shock to the heart. This symptom is not caused by a physical disorder such as a fracture of the ribs or sternum or damage to the heart muscle due to an impact, but due to a functional disorder of the heart such as ventricular fibrillation due to the impact, the strength of the impact is too weak. It is known to develop regardless.

  And since it has been reported that the onset of such heart concussion is high in baseball, softball, lacrosse, hockey, and other ball games, the heart that prevents the onset of heart concussion during ball games is reported. As a protective device, for example, (1) for fixing to a wearer's chest on a heart protection pad configured by providing a soft abutment body on the back surface of a hard plate having a substantially spherical cross section covering the center of the chest of the wearer One with a strap (see Patent Document 1 below) or (2) a plate-like member made of a soft shock absorbing material spread on the heart equivalent of clothes (see Patent Document 2 below) has been developed. ing.

  However, in the case of the above (1), although the impact on the heart can be effectively suppressed by the impact force inducing action by the hard plate and the impact force absorbing action by the impact absorbing material, Since the strap for fixing must be worn separately from the uniform and the shirt for ball games such as the undershirt worn underneath, the wearer's exercise load during ball game is as much as the band is worn. There is a problem of increasing.

  Further, in the case of (2) above, although it is possible to suppress an increase in the wearer's exercise load during ball games as in (1) above, the effect of absorbing the impact force by the soft shock absorber is sufficient for the heart. There is a problem that the impact cannot be sufficiently suppressed, and there is also a possibility that problems such as deformation, transformation, or damage may occur in the plate-like member due to the washing of the ball game shirt.

In order to solve these problems, for example, in the technique of (1) above, a blade-proof or bullet-proof outerwear in which a pocket portion having the same shape as the protective pad is provided on the back surface of the outerwear (see Patent Document 3 below) In other words, it is conceivable to form a pocket-ball heart protection shirt in which the heart protection pad is detachable by forming a pocket portion having the same shape as the heart-protection pad in the ball game shirt.

  The depth of the chest side of the space S is formed with a depth larger than the set chest side displacement depth of the central portion 2A of the pad body 2 due to impact during ball game. The pad main body 1A is prevented from contacting the heart part A due to the displacement of the part 2A.

  Next, a procedure for attaching the heart protection pad 1 to the undershirt 2 will be described.

  The both sides of the heart protection pad 1 are folded inward, and the heart protection pad 1 is inserted into the pad insertion / removal port 3d of the undershirt 2 from the convex lower part 1g side (the state shown in FIG. 8 (a)). From that state, while the pad insertion / removal port 3d is gradually expanded toward the expansion side by the insertion guide portion 1f of the heart protection pad 1 (the state shown in FIG. 8 (b)), the heart protection pad 1 is moved to the pad insertion / removal port 3d. The card is gradually inserted and the heart protection pad 1 is inserted into the pocket. At this time, since the pad insertion / removal port 3d is deformed to the contraction side by the elastic restoring force, the heart protection pad 1 does not fall off from the pad insertion / removal port 3d.

  The heart protection pad 1 inserted into the pocket is guided toward the central portion 3e of the concave bottom portion 3c along the left arm side inclined bottom portion 3f of the pocket portion 3 by gravity or an operation by the inserter. The convex lower portion 1g of the heart protection pad 1 is engaged with the central portion 3e of the concave bottom portion 3c, and the heart protection pad 1 is attached to the undershirt 2 in a state of being disposed on the shirt heart equivalent portion 2b (the state of FIG. 4). ).

  As the relatively hard synthetic resin constituting the pad main body 1A, for example, polycarbonate, ABS, AES, PP, PE, PET, PVC or the like is adopted, and the soft material constituting the abutting portion 1B is used. For example, EVA, PE, urethane, foaming urethane, olefinic elastomer, etc. are employed.
