Description

本発明は、タイヤのパンクを検査するためのパンク検査器具及びパンク検査装置に関する。   The present invention relates to a puncture inspection instrument and a puncture inspection apparatus for inspecting a tire for puncture.

自動車の中古のタイヤを販売する場合は、タイヤをホイールに装着した後にタイヤに圧縮空気を注入して、タイヤに空気の漏れる穴等の部位が存在するか存在しないかを検査し、検査終了後にタイヤをホイールから取り外している。そのため、タイヤをホイールに装着したりホイールから取り外したりする作業が面倒であるという欠点がある。そこで、特許文献1で開示された検査装置を利用してタイヤのパンクを検査することも考えられる。しかしながら、特許文献1で開示された検査装置は、2個のスピンドルに別々に設けられたディスクでタイヤを両側から挟んだまま回転してタイヤの転がり抵抗を測定する据え置き型の装置であるので、大掛かりな機構であるうえ、携帯に不向きであり、にわかに採用しがたいという欠点がある。   When selling second-hand tires for automobiles, inject compressed air into the tires after mounting the tires on the wheels, and inspect the tires for the presence or absence of holes such as holes that allow air to leak. The tire is removed from the wheel. For this reason, there is a drawback that the work of attaching and removing the tire to / from the wheel is troublesome. Therefore, it is conceivable to inspect tire punctures using the inspection apparatus disclosed in Patent Document 1. However, since the inspection apparatus disclosed in Patent Document 1 is a stationary apparatus that measures the rolling resistance of a tire by rotating while sandwiching the tire from both sides with disks separately provided on two spindles, In addition to being a large-scale mechanism, it is not suitable for carrying and has the disadvantage of being difficult to adopt.

又、図2において、パンク検査器具1の使い方について説明する。例えば、ガスケット7が取っ手5の収容部22に収容される。そして、支持部材2の雄ねじ部9がタイヤ31の側からディスク3の孔部14及びガスケット7の貫通孔27を経由して取っ手5の雌ねじ部23に結合されて雄ネジ部5の奥部に突き当てられることにより、ディスク3と取っ手5とガスケット7とが支持部材2の一端部の側に取り付けられる。又、ガスケット8が取っ手6の収容部25に収容される。そして、支持部材2の雄ねじ部10がディスク3の側からタイヤ31の中央開口部32とディスク4の孔部19とガスケット8の貫通孔28とを経由して取っ手6の雌ねじ部26に結合されて、ディスク4と取っ手6とガスケット8とが支持部材2の他端部の側に取り付けられる。尚、ディスク3と取っ手5とガスケット7とが支持部材2の取り付けられるのと、ディスク4と取っ手6とガスケット8とが支持部材2に取り付けられるのとは、どちらが先でもよい。   Moreover, in FIG. 2, the usage of the puncture inspection instrument 1 is demonstrated. For example, the gasket 7 is accommodated in the accommodating portion 22 of the handle 5. Then, the male threaded portion 9 of the support member 2 is coupled to the female threaded portion 23 of the handle 5 from the tire 31 side via the hole 14 of the disk 3 and the through hole 27 of the gasket 7, and is located at the back of the male threaded portion 5. By being abutted, the disk 3, the handle 5, and the gasket 7 are attached to the one end side of the support member 2. Further, the gasket 8 is accommodated in the accommodating portion 25 of the handle 6. The male threaded portion 10 of the support member 2 is coupled to the female threaded portion 26 of the handle 6 from the side of the disk 3 via the central opening 32 of the tire 31, the hole 19 of the disk 4, and the through hole 28 of the gasket 8. Thus, the disk 4, the handle 6, and the gasket 8 are attached to the other end side of the support member 2. Note that either the disk 3, the handle 5, or the gasket 7 is attached to the support member 2, or the disk 4, the handle 6, or the gasket 8 is attached to the support member 2, whichever comes first.

上記のようにディスク3;4と取っ手5;6とガスケット7;8とがタイヤ31の中央開口部32から両側に突出する両端部に取り付けられたことに伴い、図1に示すように、ディスク3の円盤部11とディスク4の円盤部16とがタイヤ31の中央開口部32に取り込まれ、例えば、ディスク3のリム部12とディスク4のリム部17とがタイヤ31のビード33;34を互いに外側から空気を漏れないように気密に支持する。これにより、ディスク3;4がタイヤ31を両側から挟む態様になる。   As shown in FIG. 1, the disc 3; 4, the handle 5; 6, and the gasket 7; 8 are attached to both ends protruding from the central opening 32 of the tire 31 on both sides as described above. The disc portion 11 of the disc 3 and the disc portion 16 of the disc 4 are taken into the central opening 32 of the tire 31. For example, the rim portion 12 of the disc 3 and the rim portion 17 of the disc 4 form the beads 33; Support each other so that air does not leak from the outside. As a result, the discs 3 and 4 sandwich the tire 31 from both sides.

以上のようにパンク検査器具1がタイヤ31に装着された後、図外のコンプレッサーから延びるエアーノズルから供給される圧縮空気がエアーバルブ15;20の一方からタイヤ31と支持部材2とディスク3;4とガスケット7;8で囲まれた空間35に注入された後、上記エアーノズルがエアーバルブ15;20の一方から外される。上記注入された圧縮空気によりタイヤ31のビード33;34がリム部12;17に押し付けられると共に、支持部材2とディスク3;4との隙間がガスケット7;8で密封されているので、上記空間35に注入された圧縮空気がパンク検査器具1の外部に漏れない。   After the puncture inspection instrument 1 is mounted on the tire 31 as described above, compressed air supplied from an air nozzle extending from a compressor (not shown) is supplied from one of the air valves 15; 20 to the tire 31, the support member 2, and the disc 3; 4 and the gasket 7; 8, the air nozzle is removed from one of the air valves 15; 20. The bead 33; 34 of the tire 31 is pressed against the rim portion 12; 17 by the injected compressed air, and the gap between the support member 2 and the disk 3; 4 is sealed with the gasket 7; The compressed air injected into 35 does not leak to the outside of the puncture inspection instrument 1.

又、図1に示すように、水槽36は、上方に開放された貯水部37と、水槽36の上開口の縁部に一対の受部38;39を上方に開放された凹状に備える。水槽36の貯水部37には水40が溜められる。そして、パンク検査器具1の装着されたタイヤ31が水槽36の上開口から内部に挿入される。それに伴い、パンク検査器具1が水槽36の上開口を跨ぎ、取っ手5;6が受部38;39に個別に収容され、タイヤ31のパンク検査器具1よりも下に突出する部分が水槽36の水40に浸かる。このようにタイヤ31の一部が水40に浸かった状態において、人が手をタイヤ31の水槽36よりも上方に突出した部分にかけてタイヤ31を回すと、タイヤ31が取っ手5;6を回転中心として円周方向に回転する。このように人がタイヤ31を回転させながら、タイヤ31の水40に浸かった部分から気泡が出るか出ないかを目視する。   As shown in FIG. 1, the water tank 36 is provided with a water storage part 37 opened upward and a pair of receiving parts 38; 39 in a concave shape opened upward at the edge of the upper opening of the water tank 36. Water 40 is stored in the water storage section 37 of the water tank 36. Then, the tire 31 on which the puncture inspection instrument 1 is mounted is inserted into the inside through the upper opening of the water tank 36. Accordingly, the puncture inspection instrument 1 straddles the upper opening of the water tank 36, the handles 5; 6 are individually accommodated in the receiving portions 38; 39, and the portion of the tire 31 that protrudes below the puncture inspection instrument 1 is the water tank 36. Immerse in water 40. When a part of the tire 31 is soaked in the water 40 in this way and a person turns his / her hand over the portion of the tire 31 protruding above the water tank 36 and rotates the tire 31, the tire 31 rotates around the handle 5; 6. Rotate in the circumferential direction. In this way, while a person rotates the tire 31, it is visually observed whether or not bubbles are generated from the portion of the tire 31 that has been immersed in the water 40.

つまり、タイヤ31に空気の漏れる部位が存在する場合は、空間35に注入された圧縮空気が上記タイヤ31の部位から水40の中に出るので、タイヤ31の水40に浸かった部分から気泡が立ち上る。よって、タイヤ31の水40に浸かった部分から気泡が立ち上れば、タイヤ31に空気の漏れる部位が存在し、タイヤ31がパンクしていることとその部位の位置とを人が確認できる。タイヤ31に空気の漏れる部位が存在しない場合は、空間35に注入された圧縮空気が当該空間から外部に出ないので、タイヤ31の水40に浸かった部分から気泡が立ち上ることはない。よって、タイヤ31が1回転してもタイヤ31の水40に浸かった部分から気泡が立ち上らなければ、タイヤ31がパンクしていないことを人が確認できる。つまり、人がタイヤ31に空気の漏れる部位が存在するか存在しないかというタイヤ31のパンクの有無を検査することができる。   That is, when there is a portion where air leaks in the tire 31, the compressed air injected into the space 35 exits from the portion of the tire 31 into the water 40, so that air bubbles are generated from the portion immersed in the water 40 of the tire 31. Get up. Therefore, if air bubbles rise from the portion of the tire 31 that has been immersed in the water 40, a portion where air leaks exists in the tire 31, and a person can confirm that the tire 31 is punctured and the position of the portion. When there is no portion where air leaks in the tire 31, the compressed air injected into the space 35 does not come out from the space, so that bubbles do not rise from the portion immersed in the water 40 of the tire 31. Therefore, if the air bubbles do not rise from the portion immersed in the water 40 of the tire 31 even if the tire 31 rotates once, a person can confirm that the tire 31 is not punctured. That is, the presence or absence of a puncture of the tire 31 can be inspected as to whether or not a portion where air leaks from the tire 31 exists.

図3を参照し、実施の形態1に係るパンク検査器具1を用いたパンク検査装置41について説明する。パンク検査装置41は、供給台42と水槽36と排出台43とを設置面44の上に一列に並べた構成である。供給台42は、これからパンクの検査を受けるタイヤ31を水槽36に供給するために載せる台であり、パンク検査器具1の装着されたタイヤを収容する溝45と、パンク検査器具1の取っ手5;6を別々に載せる2本のレール46;47とを備える。溝45は、タイヤ31を逃げる部分であり、上方と水槽36から離れた方と水槽36に近い方とに開口する。レール46;47は、溝45を間において分かれている。レール46;47の水槽36から離れた部分は水平であり、レール46;47の水槽36に近い方の部分は水槽36の側に行くに従って徐々に低くなる下り勾配の斜面になっている。   A puncture inspection apparatus 41 using the puncture inspection instrument 1 according to Embodiment 1 will be described with reference to FIG.

図3及び図4において、パンク検査装置41の使い方について説明する。人が安全具48を軸53;54を回転中心として図4に矢印X1で示す下方に倒して置き、パンク検査器具1がパンクの有無の検査対象としてのタイヤ31に装着された後、図1の空間35に圧縮空気の注入されたタイヤ31が供給台42に供給される。図3及び図4に戻り、人がタイヤ31を供給台42へと運搬して溝45に収容すると共に取っ手5;6をレール46;47の上に別々に載せる。   3 and 4, how to use the puncture inspection apparatus 41 will be described. A person puts the safety device 48 on the axis 53; 54 as the center of rotation and puts it down as indicated by the arrow X1 in FIG. 4, and after the puncture inspection instrument 1 is mounted on the tire 31 as an inspection target for puncture, FIG. The tire 31 in which compressed air is injected into the space 35 is supplied to the supply base 42. Returning to FIG. 3 and FIG. 4, the person carries the tire 31 to the supply base 42 and accommodates it in the groove 45 and places the handles 5; 6 on the rails 46; 47 separately.

次に、人が安全具48を軸53;54を回転中心として図4に矢印X2で示す上方に回転する。この安全具48の矢印X2で示す方向への回転は、水平部49が取っ手5の上に配置された位置で停止し、それ以上、安全具48が矢印X2で示す方向に回転しないようになる。そして、人が供給台42に設けられた図外の鉤材を安全具48に掛けて、安全具48が矢印X1で示す方向に不意に倒れないようにしておく。その後、人が手をタイヤ31の供給台42よりも上方に突出した部分にかけてタイヤ31を水槽36の側に回転する。それに伴い、取っ手5;6がレール46;47の上を転がりならが、タイヤ31が水槽36の側に移動する。   Next, the person rotates the safety device 48 about the shafts 53 and 54 as the center of rotation, as indicated by the arrow X2 in FIG. The rotation of the safety device 48 in the direction indicated by the arrow X2 stops at the position where the horizontal portion 49 is disposed on the handle 5, and the safety device 48 does not further rotate in the direction indicated by the arrow X2. . Then, a person puts a saddle member (not shown) provided on the supply base 42 on the safety device 48 so that the safety device 48 does not unexpectedly fall in the direction indicated by the arrow X1. Thereafter, the person rotates his / her tire 31 toward the water tank 36 by placing his / her hand over a portion protruding above the supply base 42 of the tire 31. Accordingly, the handle 5; 6 rolls on the rails 46; 47, but the tire 31 moves to the water tank 36 side.

そして、タイヤ31が水槽36に近づいた所において、人が安全具48を軸53;54を回転中心として図4に矢印X1で示す下方に倒した後、人がタイヤ31を供給台42から水槽36に移す。これにより、タイヤ31のパンク検査器具1よりも下方の部分が水槽36の水40に浸かり、パンク検査器具1の取っ手5;6が受部38;39に収容される。その状態において、人がタイヤ31を取っ手5;6を回転中心として円周方向に回転しながらタイヤ31のパンクの有無を検査する。パンクの検査が終了すると、人がタイヤ31を水槽36から排出台43の上に移動する。   Then, at the place where the tire 31 approaches the water tank 36, the person falls the tire 31 from the supply stand 42 to the water tank after the safety device 48 is tilted downward as indicated by the arrow X1 in FIG.
