Abstract

<P>PROBLEM TO BE SOLVED: To provide a function to prevent the cardiac concussion from occurring in the normal protector for ball game by incorporating the protection pad against cardiac concussion having full buffing function therewith, while complying with the required and full safety standards stipulated to prevent the cardiac concussion causing frequent sudden deaths. <P>SOLUTION: The protector for ball game has a protection pad body constituting a unsymmetrical form, since the heart pad is more incorporated at the heart side where the pad member is inserted in the rib cage to cover fully the range to be protected, mainly the heart, and not to prevent the entire movement of the user. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

    The present invention relates to the incorporation of a protective pad that prevents cardiac concussion into a ball game protector such as baseball.

    The recent concussion that causes frequent sudden deaths is the second most common cause of death among young athletes.

    Each competition group is worried about this, and established a special committee together with academics, consumer goods safety associations, equipment manufacturers associations, etc., to investigate the occurrence of accidents in Japan and overseas and the suitability of equipment, etc. The standard of the shaking pad was made.

In the first place, recent research that heart concussion causes fibrillation by receiving a relatively light impact during the very narrow period of heartbeat timing and left ventricular contraction, which has developed into concussion and causes sudden death. I understand. According to an American medical journal publication, a conventional protector that is commercially available is able to protect against fractures and trauma, but is not sufficient to prevent the development of subtle left ventricular fibrillation. It was announced that there was. In order to be able to suffice, it has been found that it is necessary to protect a circular range with a considerable buffering force around the heart and a diameter of less than 20 centimeters (in adults). It is essential that the inside is protected uniformly.

    Even in a catcher wearing a ball game protector, it is essential and urgent to have a function to avoid the onset of cardiac concussion. A catcher or goalkeeper who wears a protector shaped to cover the whole from the neck to the bottom and from the waist to the top of the ball game, hinders free movement of the body due to armor, such as catching and returning the pitched or shot puck It is inevitable that you must not.

However, the impact resistance required by the heart concussion pad and the size of the protection range are incompatible with the design type of the conventional protector pad, which has excellent exercise performance.

    In the design of a pad dedicated to cardiac concussion protection, if a pad body that satisfies the standards can be formed by developing materials that satisfy the protection performance, combining conventional materials, etc., wear it under the competition clothing or wear it outside the competition clothing. Even if it is a thing, it is comparatively easy regardless of a symmetrical asymmetric type to consider the position of the heart and to devise the design purposefully because it is a dedicated pad alone.

    In ball games, we would like to incorporate the heart-shock protection pad part into the base part of the protector body for goalkeepers and goalkeepers, which have been formed symmetrically for the purpose of defensive purposes, without sacrificing the performance.

    The buffer requirement value of the protective pad, which is targeted to prevent the weak ventricular fibrillation that is the origin of cardiac concussion, only needs to satisfy the performance as a defense against trauma and fracture and as an extension of the ball catcher. It is so expensive that it cannot be compared to that of the catcher's protector.

    Inevitably, high performance and expensive cushioning materials are required. Some of the materials are gel-like or semi-gel-like materials that are not foamed materials, those that incorporate a rigid plate body such as metal, or even foamed materials that have a rapidly collapsing type material, that is, the limit of buffer performance, There are some attempts to avoid “bottoming”.

    It is clear that neither of these materials is suitable for use in a ball protector that covers the entire upper body. If the former is adopted as a whole, it will reach a considerable weight and is not practical. In the latter case, the part that has been shocked once cannot exert its buffering performance again, so if the shock is received, the entire protector will be discarded, or it will be a major repair at the manufacturing factory each time. Although it is possible to manufacture a protector that can be attached and detached only for that part, it is apparent that the cost is increased.

    In the protector according to the present invention, a material such as a foam material that can be used repeatedly, or a combination thereof, the total thickness of the base portion of the conventional protector and the buffer protrusion is regarded as a practical thickness, and the materials are laminated so as to be finished within the thickness. Therefore, we decided to create an effective part as a heart-shock protection pad and incorporate it into the body of the protector. It is obvious that the required thickness for effectively functioning as a heart-shock protection pad body varies depending on the performance of the foam material employed and the combination thereof, and there are differences due to differences in required values depending on the type of ball game.

    In the protector for ball games, the groove pad that creates the flexibility of the entire protector so that the heart shock protection pad part and the peripheral buffer part that does not affect the heart shock are integrated with each other and there is no extreme height difference, etc. In order not to hang on a heart-shock protection pad that is uniform and necessary and has sufficient spread, it is incorporated in a location that is slightly eccentric from the center of the chest to the left side of the heart. In the thorax region, a protector body having a left-right asymmetric shape is formed.

  By adopting such a method, it is possible for a ball protector to incorporate a newly-developed and reusable foam material and a new combination of heart-shock protection pads without significantly disturbing the proven design. It was.

    In detail, the right handed arm side of the entire protector can be shaped with sufficient grooving to create a flexible structure, which has been proven in motor performance, while the left heart side is severe. As a result of incorporating a heart-shock protection pad part that requires strong anti-shock buffer performance, it has a left-right asymmetric shape, and it is possible to produce a ball game protector with a shape that secures contradictory protection performance and exercise performance as a whole It is.

    Hereinafter, embodiments of the present invention will be described with reference to FIGS.

    FIG. 1 shows an example of a protector having a symmetrical shape for a conventional baseball catcher. 1 to 4 groups of buffer protrusions are provided, and 5 is a groove line portion. The neck pad A is installed on the neck, the outer periphery of the main body is finished with a B-rim helicopter, and worn by the shoulder harness C and the anchor D of the back harness (the back harness is omitted). Among these, 2 is a body side part extension protection projection part similar to the A neck extension protection part (neck guard).

    FIG. 2 shows an embodiment of a protector in which a heart / cardiac pad portion is incorporated in the protector as described above. As in FIG. 1, the first to fourth groups of buffer protrusions, 5 are the groove portions, and the extended buffer protrusions A and D and the harness are the same as in FIG. 6 is a heart-shock prevention pad part incorporated in accordance with safety standards, 6 'is a circle indicating the protection range of the heart thorax according to the standard, R is its radius, and is determined to be 9 cm in adults. ing.
