Abstract

【課題】車いすに浮力を与え、水没の危険を避け、かつ、浮力体を硬質ウレタンなど固く軽い素材に変えて、浮力を確保し、尚衝撃に強い救命胴衣として人体を守る事を可能にする浮上型車いすを提供する。
【解決手段】ゴムチューブに硬質ウレタンを注入する事で堅く変形のない性質を利用したチューブ状浮力体を装着し津波や水害時の避難の際、水面から全体が浮く様にして、浮遊障害物から身体を守る事ができる浮上型車いすを形成する。また硬質ウレタンの独立気室構造体を使用することで時間が経過しても水が浸透することはない。発泡ポリエチレン素材は時間経過とともに水が浸透するので浮力が落ち、硬質ウレタンは水が浸透しないので同じ浮力を継続することが出来る。
【選択図】図１[PROBLEMS] To provide buoyancy to a wheelchair, avoid the danger of submersion, and change the buoyancy body to a hard and light material such as hard urethane to ensure buoyancy and to protect the human body as a life jacket that is still strong against impact Provide floating wheelchairs.
SOLUTION: A tube-shaped buoyant body that uses rigid and non-deformable properties is injected by injecting hard urethane into a rubber tube so that the entire surface floats from the surface of the water when evacuating in the event of a tsunami or flood. Form a floating wheelchair that can protect the body from Moreover, water does not permeate even if time passes by using the independent air chamber structure of hard urethane. Since the foamed polyethylene material penetrates water over time, the buoyancy decreases, and the hard urethane does not penetrate the water, so the same buoyancy can be continued.

Description

本考案は、身障者用車いすに固い硬質発泡ウレタン浮力材を注入したゴムチューブを装着する事で水に沈むことない車いすを完成させる技術である。 The present invention is a technology for completing a wheelchair that does not sink in water by mounting a rubber tube into which a hard foamed urethane buoyant material is injected into a wheelchair for the disabled.

従来の車いすは、金属やプラスチックが素材が主な素材で浮力に乏しく水没の危険があり
水難時でも車いすから離れられない身障者にとって危険な状態になりうる。 Conventional wheelchairs are mainly made of metal or plastic and have a low buoyancy, so there is a danger of being submerged.

浮力が無い為に人命に関わる危険が発生する欠点があった。チューブが衝撃を吸収することで衝撃からも利用者を守る。 The lack of buoyancy has the disadvantage of creating dangers related to human life. The tube protects the user from the impact by absorbing the impact.

実願２００８−１２０２Actual application 2008-1202

通常型車いすは多くの金属部品で構成されている為、水面での浮上は困難である。津波や水害時に車いす利用者が避難する際車いす自体が沈んでしまう事は危険である。 Since normal wheelchairs are composed of many metal parts, it is difficult to ascend on the water surface. When a wheelchair user evacuates during a tsunami or flood, it is dangerous that the wheelchair itself sinks.

上記課題を解決する為に、ゴムチューブに硬質ウレタンを注入する事で堅く変形のない性質を利用したチューブ状浮力体を車椅子の外部にベルト等で装着固定し安定した浮力をもつ車いすにできる。水面から全体を浮かせ浮遊障害物から身体を守る事ができる浮上型車いすを構成する。
In order to solve the above-mentioned problems, a rigid buoyancy body utilizing the property of being hard and not deformed by injecting hard urethane into a rubber tube can be attached and fixed to the outside of the wheelchair with a belt or the like, so that a wheelchair having stable buoyancy can be obtained. A floating wheelchair that can float from the surface of the water and protect the body from floating obstacles.

図２の硬質ウレタンで構成された車いす用チューブの形状は空気注入時と変わらぬ形状だが、硬度は著しく向上する。 The shape of the wheelchair tube made of rigid urethane in FIG. 2 is the same shape as when air is injected, but the hardness is remarkably improved.

以下、本考察の実施の形態を図に基づいて説明する。 Hereinafter, embodiments of the present discussion will be described with reference to the drawings.

通常型の車いすに浮力体を装着した図１から図３であるが、浮力体のない状態
各図中央部の車いす自体は金属、プラスチックなどの比重の水より重い素材で作られているため水上では沈んでしまう。
硬質発泡ウレタンで構成されたチューブが浮力体として装着された図1から３の浮力体付き車いすは水面で浮上できる。 1 to 3 with a buoyant body attached to a normal wheelchair, but without the buoyant body. Then it will sink.
The wheelchair with a buoyant body shown in FIGS. 1 to 3 in which a tube made of rigid urethane foam is attached as a buoyant body can float on the surface of the water.

水に浮く車いすは非常災害時にも水上にて身障者を支え人体を守ることが出来、身体防衛道具として活躍できる。

A wheelchair that floats on water can support people with disabilities and protect the human body in the event of an emergency, and can be used as a body defense tool.

Claims

By injecting hard urethane into the rubber tube, a tube-like buoyant body that uses the rigid and non-deformable nature can be attached to float the entire surface from the water surface and protect the body from floating obstacles when evacuating during a tsunami or flood. A floating wheelchair.
