Description

本発明は、エアー充填用安全装置に関する。   The present invention relates to an air filling safety device.

自動車のタイヤにエアーを充填する際、タイヤ内部のスチール部分の損傷やタイヤの側壁（サイドウォール）の損傷によってバースト（破裂）が発生することがある。タイヤがバーストした場合、爆発的に噴射するエアーの風圧によりタイヤが暴れたり、金属製のホイールが外れて飛んだりして、近隣の作業者に大きな危険を及ぼしていた。このため、従来、タイヤの幅より大きな間隔を空けて立設された左右一対の側枠を有する安全柵にタイヤを収納した状態で、エアー充填の作業が行われている（特許文献１参照）。   When air is filled into an automobile tire, a burst (rupture) may occur due to damage to a steel portion inside the tire or damage to a sidewall of the tire. When a tire bursts, the tires are violated by the wind pressure of the explosively injected air, or the metal wheels come off and fly, which poses a great danger to nearby workers. For this reason, conventionally, an air filling operation has been performed in a state where the tire is housed in a safety fence having a pair of left and right side frames that are erected with an interval larger than the width of the tire (see Patent Document 1). .

しかし、タイヤがバーストを起こした時、高圧のエアーによる爆風がタイヤの側壁（サイドウォール）から吹出すこととなる。従来のエアー充填用安全柵は、タイヤのバーストに伴ってサイドウォールから吹出す爆風を防ぐことができなかった。この爆風の衝撃波によって周囲の物品を破損したり、破片が飛散したりして、作業者のケガや重大な事故が発生する虞れがあった。
また、エアー充填用安全柵自体が大型の立体構造体であるため、構造が複雑で、重量が重く、しかも、バーストの衝撃に耐えられるように、アンカーボルト等で設置面に固定する必要があり、移動や運搬が面倒であるという欠点があった。 However, when the tire bursts, a blast from high-pressure air blows out from the tire sidewall. The conventional air-filling safety fence could not prevent the blast that blows out from the sidewall as the tire bursts. The shock wave of the blast may damage surrounding articles or scatter fragments, resulting in injury to workers and serious accidents.
Also, because the air-filling safety fence itself is a large three-dimensional structure, it must be fixed to the installation surface with anchor bolts, etc. so that the structure is complex, heavy, and can withstand the impact of burst. There was a drawback that it was troublesome to move and transport.

そこで、本発明は、移動・運搬が容易で、取扱いし易く、かつ、タイヤがバーストした際の爆風や破片飛散の危険を低減できるエアー充填用安全装置を提供することを目的とする。   Accordingly, an object of the present invention is to provide an air filling safety device that is easy to move and transport, is easy to handle, and can reduce the risk of blast and debris scattering when a tire bursts.

The operation of wrapping the tire is simply performed by placing the tire T on the windbreak film body 1 in a vertical posture or an inclined posture, and making the two sides 1A, 1B of the windbreak film body 1 close to each other or overlapping each other to make a two-fold shape. It is possible to carry out work quickly and easily in a short time. The flexible windbreak film body 1 can flexibly and skillfully reduce the risk of a blast Z (shock wave) due to a burst.

また、上記防風膜体１は、可撓性布体１１と、該布体１１に固着された可撓性の補強帯体２とを、備えているので、防風膜体１の強度が向上して、タイヤＴのバーストに伴う爆風Ｚの衝撃波に耐え得る。補強帯体２の両端部によって取付部３を形成することも可能となり、タイヤＴがバーストした際、取付部３が破れたり外れたりすることなく、防風膜体１を荷台Ｐに確実に止着できる。   Further, since the windbreak film body 1 includes the flexible cloth body 11 and the flexible reinforcing band body 2 fixed to the cloth body 11, the strength of the windbreak film body 1 is improved. Thus, it can withstand the shock wave of the blast Z accompanying the burst of the tire T. It is also possible to form the attachment portion 3 by both ends of the reinforcing band 2, and when the tire T bursts, the attachment portion 3 is not torn or detached, and the windbreak film body 1 is securely fixed to the loading platform P. it can.

また、上記使用状態に於て、上記タイヤＴを２つ折り状として包み込んだ上記防風膜体１の左右の開口側の側端縁６，６を着脱自在に連結する面状ファスナー手段５を備えているので、タイヤＴがバーストした際の爆風Ｚによって開口部１５が過大に拡開することを防止し、タイヤＴが転動しつつ飛び出したり、破片が飛散することを防止できる。   Further, in the state of use, there is provided a surface fastener means 5 for detachably connecting the side edges 6 and 6 on the left and right opening sides of the windbreak film body 1 encasing the tire T in a folded shape. Therefore, it is possible to prevent the opening 15 from being excessively expanded by the blast wind Z when the tire T bursts, and to prevent the tire T from jumping out while rolling or debris scattering.
