【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、各種のスポーツに用いる防具1例えば。[Detailed description of the invention] [Industrial application field] The present invention provides protective gear 1 for use in various sports, for example.
剣道、空手等の格闘技に使用する防具、アメリカンフッ
トボール、アイスホッケー、野球等の球技に使用する防
具に関し、特に剣道の網台として使用するに好適なスポ
ーツ用防具に関する。The present invention relates to protective gear used in martial arts such as kendo and karate, and protective gear used in ball games such as American football, ice hockey, and baseball, and particularly to sports protective gear suitable for use as a net stand in kendo.
従来より1種々なスポーツ用防具が使用されており。 Traditionally, various types of sports protective gear have been used.
その材質も天然素材、プラスチック等積々のものがある
。これを剣道用用台を例に説明すると、一般に剣道用用
台は、竹、皮等で構成されている。竹製の用台構成は、
輻20〜300の竹を一方向に並べ、更に表面を皮等で
覆っている。ところが、この竹製用台では一方向の強度
は十分であるが、他方向の強度が不足しており5 この
ため、竹刀で衝撃を加えた時、容易に曲がり1体に直接
衝撃がかかり、叩かれた時、痛い。また。There are many different materials such as natural materials and plastics. To explain this using a kendo stand as an example, a kendo stand is generally made of bamboo, leather, or the like. The structure of the bamboo stand is
Bamboos of 20 to 300 diameters are lined up in one direction, and the surface is further covered with leather. However, although this bamboo stand has sufficient strength in one direction, it lacks strength in other directions5.For this reason, when an impact is applied with a shinai, it easily bends and a direct impact is applied to the stand. It hurts when I get hit. Also.
保管時においても左右方向に無理な力がかかると容易に
壊れる。Even during storage, it can easily break if excessive force is applied in the left and right directions.
一方、皮製の網台においても衝撃の繰り返しにより。On the other hand, due to repeated impact on the leather net stand.
へこみ或いは皮のやぶれ等が発生し、耐久性に問題があ
る。There are problems with durability as dents or peeling of the skin occur.
また、天然材料である竹、皮等は、水分を吸収し易いた

いう欠点もある0表面の塗装についても、今まで十分に
検討されていないのが現状で、竹刀の繰り返し衝撃によ
り1表面にきす、はがれが生じやすいものであった。In addition, since natural materials such as bamboo and leather easily absorb moisture, surface painting has not been sufficiently studied until now. At present, there is no such thing, and scratches and peeling tend to occur on one surface due to repeated impacts from the Shinai.
竹、皮の天然素材に対し、プラスチックを使用した剣道
周胴台も提案されている。例えば、ABS樹脂で一体成

た剣道周胴(実公昭47−41571号、特開昭60−
122583号公報参照)等が提案されている。In addition to natural materials such as bamboo and leather, kendo shododai made of plastic have also been proposed. For example, a Kendo body made of ABS resin (see Japanese Utility Model Publication No. 45-32821)
, Sports armor made by hardening a material made by impregnating a flexible cloth with an adhesive resin (see Japanese Patent Application Laid-Open No. 60-66770 No. 1) 9 Glass fibers embedded in polyester resin on one side of a synthetic resin material Kendo wraparound trunk formed by laminating reinforcing layers (Utility Model Publication No. 41571/1983, JP-A-60/1983)
122583) etc. have been proposed.
しかしながら、従来のプラスチックを利用した剣道周胴
は、使用に支障のない重さとした場合には、耐衝撃性1
強度、硬度等が不足し、逆に、必要な耐衝撃性。However, the conventional kendo wraparound trunk made of plastic has an impact resistance of 1.
It lacks strength, hardness, etc., but on the contrary, it lacks the necessary impact resistance.
強度、硬度等を与えた場合には9重量が重くなり、使用
に耐え得るものではなく、このため、一般には使用され
ていないのが現状である。When strength, hardness, etc. are added, the weight increases, making it unusable, and for this reason, it is not generally used at present.
そこで2本発明者等は、この様な問題点をなくすために
2種々検討した結果、軽量芯材の両側を繊維強化プラス
チックで補強することにより、極めて軽量でありながら
、耐衝撃性1強度、硬度に優れた材料を得ることができ
、これが剣道周胴台をはじめ、他のスポーツ用防具に好
適に使用しうろことを見出し1本発明に到達した。In order to eliminate these problems, the inventors of the present invention investigated two different methods, and found that by reinforcing both sides of the lightweight core material with fiber-reinforced plastic, it was possible to achieve impact resistance of 1 strength, while being extremely lightweight. The inventors have discovered that a material with excellent hardness can be obtained and that this material can be suitably used for kendo circumdodai and other sports protective gear, and have thus arrived at the present invention.

変形が生じないので1体に対する衝撃が少なく痛さをあ
まり感じない、更に、長期間使用しても、変形、腐食が
無い、従来の竹製の剣道用用台では。The sports protective gear of the present invention having the above structure has a structure in which fiber-reinforced plastic is placed on both the front and back sides of the lightweight core material, so it has high rigidity and high impact strength despite its light weight.Therefore, one aspect of the present invention When applied to a kendo stand, it is lightweight and extremely easy to use, and even when hit with a bamboo sword, local deformation does not occur, so there is less impact on the body, so you do not feel much pain, and it can be used for a long time. However, traditional bamboo kendo stands do not deform or corrode.

を減衰させる等の作用を有している。Furthermore, the soft thin film layers interposed between the lightweight core material and the fiber-reinforced plastic, between the layers within the lightweight core material, and between the layers within the fiber-reinforced plastic prevent the adhesive surfaces of each layer from peeling off and reduce the impact that may be exerted on the armor. It has the effect of mitigating the impact, preventing destruction of the fiber-reinforced plastic layer, improving the impact resistance of armor, and damping vibrations, sounds, etc.
このため、防具の寿命を一層長くすることができる。Therefore, the life of the armor can be further extended.
軟質薄膜の層を備えた防具を剣道用用台に適用すると。When a protective gear with a layer of soft thin film is applied to a kendo stand.
