Description
【０００１】[0001]
本考案は、自転車におけるチエン錠取付構造に関するものであり、チエン錠を 使用時には施錠を容易迅速に行え、またチエン部を長くして例えば前輪を施錠可 能になり、他面チエン錠の不使用時には容易・迅速に収納可能で、収納後は外部 から見えずすっきりと体裁よく、かつチエン錠の紛失も無くすようにしたもので ある。 The present invention relates to a chain lock mounting structure for a bicycle. When the chain lock is used, it can be locked easily and quickly, and the chain can be lengthened to lock the front wheel, for example, and the chain lock on the other side can be eliminated. At times, it can be stored easily and quickly, and after storage it is neat and clean, with no loss of chain locks.

自転車の盗難防止用の錠としては、従来より次のようなものがある。 １）例えば箱形錠や馬蹄錠の如く、前車輪または後車輪のスポークの間にカン ヌキを入れて、車輪の回転をロックするもの。 BACKGROUND ART Conventionally, there are the following locks for preventing bicycle theft. 1) For example, a box lock or horseshoe lock that locks the rotation of the wheels by inserting a blank between the spokes of the front or rear wheels.
【０００３】 また、２）例えばラレー錠やハンドルロック錠の如く、前ホーク肩部やヘッド セット部で前ホークやハンドルの回動を係止するもの。2) Locking the front hawk and the handle at the front hawk shoulder portion and the headset portion, such as a Raleigh lock and a handle lock lock.
【０００４】 さらに、３）例えばチエン錠やワイヤー錠やシャックル錠の如く、単独に携行 して用いる錠で、自転車の車輪その他の任意の箇所を任意の物に引っ掛けて係止 可能なもの、等がそれである（例えば「自転車便覧」第４版，財団法人自転車産 業振興協会発行の第８６６頁，第８６８頁，実開昭５４−２３４６３号公報，実 開昭５４−１１８７６３号公報参照）。Further, 3) locks that are individually carried, such as chain locks, wire locks, and shackle locks, which can be locked by hooking a bicycle wheel or any other place on an arbitrary item. That is the case (see, for example, “Bicycle Handbook”, 4th edition, pages 866 and 868, published by the Association for the Promotion of Bicycle Industry, JP-A-54-233463, JP-A-54-118763).
【０００５】 上記自転車用錠の内でチエン錠やワイヤー錠は、自転車を道路の鉄柵の如き固 定物へ引っ掛けて係止できるので、箱形錠・馬蹄錠・ラレー錠・ハンドルロック 錠が、車輪やハンドルを固定したまま自転車を持ち上げて運ばれることがあるの と異なり、盗難防止性に優れている。Among the above-mentioned bicycle locks, chain locks and wire locks can be locked by hooking the bicycle on a fixed object such as an iron fence on the road, so that box locks, horseshoe locks, Raleigh locks, and handle lock locks can be used. Unlike the case where a bicycle is lifted and carried while the wheels and handles are fixed, it has excellent anti-theft properties.
【０００６】 ところがチエン錠やワイヤー錠は、箱形錠等と異なり自転車と別体であるため に、自転車走行中でチエン錠やワイヤー錠を使用しない場合に、これらの錠を別 に携行する必要がある。そこで従来一般に、不使用時のチエン錠やワイヤー錠は 自転車の荷籠内へ放り込んでおかれたり、チエン部やワイヤー部を自転車フレー ムに巻付け、端部寄りを錠に係止させて携行していることが多い。However, since chain locks and wire locks are separate from the bicycle unlike box locks, etc., it is necessary to carry these locks separately when the chain lock or wire lock is not used while riding a bicycle. There is. Therefore, in general, when not in use, chain locks or wire locks have been thrown into the luggage compartment of a bicycle, or chain chains or wire parts have been wrapped around the bicycle frame, and the lock near the ends has been locked. I often do
【０００７】[0007]
しかしながらチエン錠やワイヤー錠は、それが上記のように自転車と別体で携 行されているため、使用時即ち自転車に施錠する際には、荷籠内からあるいは巻 付けてチエン錠やワイヤー錠を解いて取り出してから、自転車の一部に引っ掛け て施錠する必要があるので、箱型錠やハンドルロック錠等に比べて施錠作業に手 間がかかり、不便である。 However, since the chain lock and wire lock are carried separately from the bicycle as described above, when used, i.e., locked on the bicycle, the chain lock or the wire lock can be wound from inside the luggage basket or wound. Since it is necessary to unfasten and take it out, and then lock it by hooking it on a part of the bicycle, locking work is more time-consuming and inconvenient than box locks or handle locks.
【０００８】 他面、チエン錠やワイヤー錠を不使用時に荷籠内へ放り込んでおくのは、荷物 を入れる際の邪魔になったり、チエン錠やワイヤー錠を取り出す際に荷物の下で 直ぐに取り出せなかったりして不便である。荷籠に入れておいたチエン錠やワイ ヤー錠は、紛失したりあるいは盗まれたりすることもある。また近時は、サドル をシートポスト付きで抜き出し、盗まれることもあるという。On the other hand, if the chain lock or wire lock is thrown into the luggage basket when not in use, it may be an obstacle when loading luggage, or the chain lock or wire lock may be immediately removed under the luggage. It is inconvenient to not have it. Chain and wire locks in the luggage can be lost or stolen. Also, recently, the saddle with a seatpost may be pulled out and stolen.
【０００９】 さらに、チエン錠やワイヤー錠を自転車フレームに巻付けて係止させておくの は、巻き付けて側端の被掛止用部を錠部に掛止させるのに手間がかかるし、あま り体裁が良くない。また、チエン錠やワイヤー錠を立パイプに巻き付けると、自 転車に乗って走行時に脚に触れて邪魔になることもあった。Furthermore, when the chain lock or the wire lock is wound around the bicycle frame and locked, it takes time and effort to wind and lock the hooked portion at the side end to the lock portion. The appearance is not good. In addition, winding a chain lock or wire lock around a vertical pipe could get in the way by touching legs while riding on a bicycle.
【００１０】 そこで、本件と同一出願人は先に、自転車のシートポストにワイヤー錠のワイ ヤー部を通挿させたもので、シートポストの上部寄り側部に孔部を形成し、該孔 部に、ワイヤー錠のワイヤー部を通挿し錠部を係止する内径の短管を装入・固着 するとともに、上記短管を設けた位置の近傍に、上記錠部の掛止用孔へ係合時に 錠部で掛止される凹凸部付きの掛止用突起を突設し、かつ、上記短管からシート ポスト内へ通挿したワイヤー部の下端部に、短管の内径より大きい抜け止め部を 設けたものを開発し、出願している（実願平６−５１５１号の明細書および図面 参照）。Therefore, the applicant of the present application first inserts the wire part of the wire lock into the seat post of the bicycle, and forms a hole in the side part near the upper part of the seat post. Insert and fix a short tube with an inner diameter that inserts the wire part of the wire lock and locks the lock part, and engages with the locking hole of the lock part near the position where the short tube is provided. At the bottom end of the wire part that protrudes from the short pipe and is inserted into the seat post, a retaining part larger than the inner diameter of the short pipe is provided. Has been developed and filed (see the specification and drawings of Japanese Utility Model Application No. 6-5151).
【００１１】 これは、ワイヤー錠を不使用時には容易・迅速に収納可能で、収納後は外部か ら見えずすっきりして体裁が良く、また使用時には施錠作業を容易・迅速に行え て、時にはサドルの盗難を防止できる、という利点がある。しかし、ワイヤー錠 の収納はワイヤー部を手でシートポストへ押し入れる手間を要し、またワイヤー 部を収納できる長さに制約がある。そのため、比較的車体から外し易く近時盗難 に遇うことが多くなった前輪までワイヤー部が届かず、前輪で施錠することがで きなかった。[0011] This is because the wire lock can be stored easily and quickly when not in use, and after storage it is neat and has a good appearance without being visible from the outside. The advantage is that theft can be prevented. However, storing the wire lock requires time and effort to push the wire portion into the seat post by hand, and there is a limit to the length that the wire portion can be stored. For this reason, the wires could not reach the front wheels, which were relatively easy to remove from the vehicle body and were often handled by theft these days, and the front wheels could not be locked.
【００１２】 本考案は、上記従来の自転車用錠やその収納構造の問題点を解決しようとする ものである。即ち本考案の目的は、使用時にはチエン部を引き出して容易・迅速 に施錠可能であり、不使用時にはチエン部が自動的に収納可能であるとともに、 収納後は外部から見えずすっきりして体裁が良く、またかつ長いチエン部を使用 可能で前輪をも施錠可能となる、自転車のチエン錠取付構造を提供することにあ る。The present invention is intended to solve the problems of the conventional bicycle lock and the storage structure thereof. In other words, the purpose of the present invention is that the chain part can be pulled out easily and quickly when it is used, and the chain part can be automatically stored when not in use. Another object of the present invention is to provide a bicycle chain lock attachment structure that is good and allows the long chain portion to be used and also locks the front wheels.

【００１９】[0019]
上記本考案に係る自転車のチエン錠取付構造の使用状態・作動状態は、次のよ うになる。 １）まず、自転車を走行させるためにチエン錠１を使用しない場合には、該チ エン錠１をシートポスト４内へ収納させておく。それには、チエン錠１を合鍵１ ３により解錠状態にした後、チエン部２を持つ手の力を緩めるだけでよい。 The use and operation states of the bicycle chain lock mounting structure according to the present invention are as follows. 1) First, when the chain lock 1 is not used to drive a bicycle, the chain lock 1 is stored in the seat post 4. To do so, it is sufficient to release the chain lock 1 with the compound key 13 and then release the force holding the chain portion 2.
【００２０】 これにより、チエン部２がフリー状態となるので、シートポスト４内の下部で 折り返し位置Ｐが引っ張りバネ８で下方へ引かれている該チエン部２は、自動的 に短管５を経て該ポスト４内へ順次に引っ張り入れられる。後は、チエン部２が 全長をポスト４内へ収納された状態で、外部に残った錠部３の円筒状部を短管５ に嵌合させておけばよい。As a result, the chain portion 2 is in a free state, so that the chain portion 2 in which the folding position P is pulled downward by the tension spring 8 in the lower portion of the seat post 4 automatically connects the short tube 5 to the short pipe 5. After that, they are sequentially pulled into the post 4. After that, with the chain portion 2 stored in the post 4 over its entire length, the cylindrical portion of the lock portion 3 remaining outside may be fitted into the short tube 5.
【００２１】 上記の場合に、ポスト内へ垂下されたチエン部２は、チエン部の下端部が下方 へ引っ張られのではなく、ポスト４内の下部寄りで折り返されて、他端部６をポ スト４内の上部寄り位置に掛止し、その折り返し位置Ｐを滑動可能に掛止金具７ で引っ掛け、該掛止金具７を引っ張りバネ８で下方へ引っ張られている。In the above case, the lower end of the chain portion 2 of the chain portion 2 suspended in the post is not pulled downward, but is folded back toward the lower portion of the post 4 and the other end portion 6 is closed. The hook 4 is hooked at a position near the upper part of the strike 4, and the folded position P is slidably hooked by a hook 7 and the hook 7 is pulled downward by a tension spring 8.
【００２２】 掛止金具７がバネ８で引かれて降下するに伴って、他端部６がポスト４内の上 部寄り位置に掛止されたチエン部２は、該掛止金具７を滑動しながら折り返し位 置Ｐを降下させることになり、チエン部２は矢印ａで示す如くポスト４内へ引っ 張り込まれるとともに、ポスト４内で掛止金具７で折り返された２重状態になる （図１参照）。その際、掛止金具７に横軸部１１を形成してあると、チエン部２ が該掛止金具７で引っ掛かることなく、スムーズに滑動して折り返される。As the latching metal 7 is pulled by the spring 8 and descends, the chain portion 2 with the other end 6 latched at a position near the upper part of the post 4 slides on the latching metal 7. While the folding position P is lowered, the chain portion 2 is pulled into the post 4 as indicated by the arrow a, and is folded in the post 4 by the hook 7 to be in a double state ( (See FIG. 1). At that time, when the horizontal shaft portion 11 is formed on the latch 7, the chain portion 2 is smoothly slid and folded back without being caught by the latch 7.
【００２３】 そのため、チエン部２がポスト４内へ引き込まれ得る長さは、単にチエン部の 下端部を引っ張ってポスト内へ引き込む場合と異なり、ポスト４内で折り返され ることで約２倍になっており、チエン部２は全長を充分にポスト４内へ収納され るので、外部に残った錠部３を短管５へ嵌合させておけばよい。（図１参照）。Therefore, the length by which the chain portion 2 can be pulled into the post 4 is approximately doubled by being folded back in the post 4 unlike when the lower end portion of the chain portion is simply pulled into the post. Since the chain portion 2 is fully accommodated in the post 4, the lock portion 3 remaining outside may be fitted into the short pipe 5. (See Figure 1).
【００２４】 これで、不使用時のチエン錠１は、容易・かつ迅速にポスト４内へ収納できた ことになり、従来のように外したチエン錠を荷物籠に入れておく手間や、ポスト ４に巻き掛けておく手間が無くなるし、自転車走行の邪魔になることも無く、か つ体裁もよい。With this, the chain lock 1 when not in use can be stored in the post 4 easily and quickly, and it is necessary to put the removed chain lock in the luggage basket as in the conventional case, and the post. There is no need to wrap it around the bicycle, it does not interfere with the cycling, and the appearance is good.
【００２５】 さらに、該チエン錠１は他端部６がポスト４内の上部寄りに掛止固定されてい るので、ポスト４から分離することが無く、自転車から取り外したチエン錠をど こかへ置き忘れたり、紛失したりすることが無くなるし、またチエン錠３を盗ま れることも無くなる。Further, since the other end portion 6 of the chain lock 1 is hooked and fixed near the upper part of the post 4, the chain lock does not separate from the post 4 and the chain lock removed from the bicycle is moved to somewhere. It will not be left behind or lost, and the chain lock 3 will not be stolen.
【００２６】 なお、チエン部２は上記の如くポスト４内で折り返して収納されることで、従 来のものより長いものを収納可能となっている。The chain portion 2 is stored in the post 4 by being folded back as described above, so that a longer one can be stored.
【００２７】 ２）次に、自転車に乗らぬ場合にこのチエン錠１で施錠する場合には、上記の 如くシートポスト４内に収納してあるチエン錠１を、錠部３をつまんでチエン部 ２を引き出し、施錠すればよい。2) Next, when locking with the chain lock 1 when not riding a bicycle, the chain lock 1 stored in the seat post 4 as described above is pinched by the lock part 3 2 should be pulled out and locked.
【００２８】 即ち、ポスト４側部の短管５に嵌合させてある錠部３をつまみ、それを外方へ 引き抜いて、引っ張りバネ８の力に抗して矢印ｂで示す如くチエン部２を引き出 す。この場合にチエン部２は、他端部６がポスト４内の上部寄りに掛止されてい るので、チエン部２が引き出されるに伴い、折り返し位置Ｐを引っ掛けた掛止金 具７も、引っ張りバネ８の力に逆らって上昇する。That is, the lock portion 3 fitted to the short tube 5 on the side of the post 4 is pinched, and it is pulled out outward, against the force of the tension spring 8 as shown by the arrow b. Pull out. In this case, since the other end 6 of the chain portion 2 is hooked toward the upper part of the post 4, the hook 7 that is hooked at the folding position P is also pulled as the chain portion 2 is pulled out. It rises against the force of the spring 8.
【００２９】 チエン部２をいっぱいまで引っ張り出すと、該掛止金具７が短管５の位置まで 来て、それ以上引き出せなくなるが、これはチエン部２の折り返し位置Ｐが短管 ５の位置まで来たことであり、チエン部２を最も長く引き出した状態である（図 ２参照）。When the chain part 2 is pulled out to the full extent, the hook 7 comes to the position of the short pipe 5 and cannot be further pulled out. This is because the folding position P of the chain part 2 reaches the position of the short pipe 5. It is here that the chain part 2 has been pulled out for the longest time (see FIG. 2).
【００３０】 そこで、このチエン部２を、例えば鉄柵のような地上固定物１６や自転車の後 輪に掛け渡した状態で、錠部３をチエン部２の一部に引っ掛けて掛止させること で（図２参照）、自転車は施錠される。もしチエン部２が長くて余った分が生じ たならば、引っ張りバネ８によりポスト４内へ自動的に収納されることになる。Therefore, by locking the chain portion 2 by hooking the lock portion 3 on a part of the chain portion 2 in a state where the chain portion 2 is hung on the ground fixed object 16 such as an iron fence or the rear wheel of the bicycle. (See Fig. 2) The bicycle is locked. If the chain portion 2 is long and an extra portion is generated, it is automatically stored in the post 4 by the extension spring 8.
【００３１】 なお、チエン部２の長さは、ポスト４内で折り返されていることで充分に長く なっているが、このチエン錠で例えば前輪の盗難防止にも用いたい場合には、ポ スト４を通常よりも長いものを用いてチエン部２をさらに長いものにし、引き出 したチエン部２を前輪に掛け渡して施錠すればよい。またこのチエン錠１をサド ル１７に引っ掛けて施錠すれば、例えばクイックロック式のサドルの盗難防止用 として用いられる。The chain portion 2 has a sufficiently long length because it is folded back inside the post 4. However, if this chain lock is also used to prevent the front wheels from being stolen, for example, the post should be used. 4 may be longer than usual to make the chain portion 2 longer, and the pulled-out chain portion 2 may be hung on the front wheel to be locked. If the chain lock 1 is hooked on the saddle 17 and locked, it can be used, for example, for preventing theft of a quick lock type saddle.

【００３３】 即ち、シートポスト４上部寄り側部に孔部を形成し、該孔部に金属製の短管５ を装入し、溶着やロウ付け等で固着してある。該短管５はチエン錠１のチエン部 ２が通挿し易いように、ポスト４の中心線に対して９０度よりも小さい角度、こ こでは約４５度程度で上方を向くように設けてある。なお、ポスト４の長さは通 常、３０ｃｍ程度のものでよいが、さらに長いチエン部２を用いたいなら、ポス ト４を７０ｃｍ程度のものにすればよい。短管５の材質は、鉄製に限らず、アル ミ合金・チタン合金等であってもよい。That is, a hole is formed on the side near the upper part of the seat post 4, and a short tube 5 made of metal is inserted into the hole and fixed by welding or brazing. The short tube 5 is provided so that the chain portion 2 of the chain lock 1 can be easily inserted, and is directed upward at an angle smaller than 90 degrees with respect to the center line of the post 4, here about 45 degrees. . The length of the post 4 is usually about 30 cm, but if it is desired to use a longer chain portion 2, the post 4 may be about 70 cm. The material of the short pipe 5 is not limited to iron, and may be aluminum alloy, titanium alloy, or the like.
【００３４】 上記短管５の内径は、チエン部２がスムーズに出・入可能で、かつチエン錠１ の円筒状の錠部３を着脱可能に嵌合できる大きさとしてある。該短管５内周には 、チエン部２の滑りと錠部３の嵌合を良くするため、例えば合成ゴムの如き弾性 材製の０リング１４を装着してある。The inner diameter of the short pipe 5 is set so that the chain portion 2 can be smoothly inserted and removed and the cylindrical lock portion 3 of the chain lock 1 can be detachably fitted. On the inner circumference of the short pipe 5, an O-ring 14 made of an elastic material such as synthetic rubber is attached to improve the sliding of the chain portion 2 and the fitting of the lock portion 3.
【００３５】 またポスト４内で上記短管５を設けた位置より上部に、チエン部２の他端部６ を掛止するために、ピン状の掛止部９を横設するとともに、該ポスト４の下端部 に、引っ張りバネの下端部を掛止するために、別体の延長パイプ１０の上端部を 嵌合固定させてある。In addition, a pin-shaped hooking portion 9 is provided laterally above the position where the short pipe 5 is provided in the post 4 in order to hook the other end 6 of the chain portion 2, and the post is also provided. An upper end of a separate extension pipe 10 is fitted and fixed to the lower end of the extension spring 10 so as to hook the lower end of the tension spring.
【００３６】 チエン錠１は、上記の如く円筒状部を有する錠部３と該錠部３に連結したチエ ン部２とからなり、チエン部２は短管５からポスト４内へ通挿されてポスト４下 部寄りへ垂下し、下方で折り返されて他端部６がポスト１内上部寄りで上記掛止 部に掛止されている。The chain lock 1 comprises a lock part 3 having a cylindrical part as described above and a chain part 2 connected to the lock part 3. The chain part 2 is inserted from the short tube 5 into the post 4. And the other end portion 6 is hooked to the above-mentioned hooking portion near the upper part of the post 1 by being folded downward.
【００３７】 またチエン部２は、下方の折り返し位置Ｐを滑動用の横軸部１１をもつ掛止金 具７で滑動可能に掛止されており、該掛止金具７はチエン部２が引き出される際 の折り返し位置Ｐの移動に伴い、チエン部２との間で滑動しながら該折り返し位 置Ｐとともに移動可能としてある。１８はチエン部２の一部に形成した被掛止環 で、ここを錠部３に入れて掛止片１２で掛止する。なお、錠部３の構造は図示の タイプのものに限らず、掛止片１２がチエン部２を掛止可能なものであればよい し、掛止具９も横ピン状のものに限らないことも勿論である。Further, the chain portion 2 is slidably locked at a lower folded position P by a latch 7 having a horizontal shaft portion 11 for sliding, and the latch metal 7 is pulled out by the chain portion 2. With the movement of the folding position P at the time of turning, it is possible to move together with the folding position P while sliding with the chain portion 2. Reference numeral 18 denotes a hooked ring formed on a part of the chain portion 2, which is put in the lock portion 3 and hooked by a hooking piece 12. The structure of the lock portion 3 is not limited to the type shown in the figure, and any structure may be used as long as the locking piece 12 can lock the chain portion 2, and the locking tool 9 is not limited to the lateral pin shape. Of course.
【００３８】 該掛止金具７と上記延長パイプ１０との間にはコイル状の引っ張りバネ８を設 けてある。即ち、掛止金具７の下端部にバネ８の上端部を掛止させ、延長パイプ １０の下端部にバネ８の下端部を掛止させてある。該引っ張りバネ８の長さは、 チエン部２が最も収納された状態でチエン部２の折り返し位置Ｐが最下位置へ来 る迄、換言すれば掛止金具７が最下位置へ来る迄、下方への引っ張り力を作用さ せるようにしてある。A coil-shaped tension spring 8 is provided between the hook 7 and the extension pipe 10. That is, the upper end of the spring 8 is hooked on the lower end of the hook 7 and the lower end of the spring 8 is hooked on the lower end of the extension pipe 10. The length of the tension spring 8 is such that the folding position P of the chain portion 2 reaches the lowest position when the chain portion 2 is most stored, in other words, until the latch 7 reaches the lowest position. It is designed to exert a downward pulling force.
【００３９】 なお、図において、１９は樹脂製チューブで、ポスト４の内周面に短管５を設 けた箇所から下端部までに設けてあり、チエン部２やバネ８の移動に伴う磨耗の 防止と、消音を兼ねたものである。In the figure, 19 is a resin tube, which is provided from the position where the short pipe 5 is provided on the inner peripheral surface of the post 4 to the lower end portion, and is protected from wear due to movement of the chain portion 2 and the spring 8. It is a combination of prevention and noise reduction.
以上の如く、本考案の自転車におけるチエン錠取付構造によれば、チエン錠の 不使用時にチエン部を自動的にシートポスト内へ収納できるとともに、収納後は 外部から見えず、すっきりして体裁も良く、またチエン錠の使用時にポスト内か らチエン部を引き出すことで容易・迅速に施錠することができ、かつ鉄柵その他 の地上の固定物や自転車の後輪に施錠できることは勿論のこと、チエン部を充分 な長さにして前輪を施錠し、盗難を防止することができる。 As described above, according to the chain lock attachment structure for a bicycle of the present invention, the chain portion can be automatically stored in the seat post when the chain lock is not used, and after storage, it can be seen from the outside and is neat and clean. Of course, when the chain lock is used, it can be locked easily and quickly by pulling out the chain part from inside the post, and it can also be locked on iron fences and other fixed objects on the ground and the rear wheel of the bicycle. You can prevent theft by locking the front wheel with a sufficient length.
【００４０】 即ち、本考案の自転車におけるチエン錠取付構造では、シートポストの側部に 形成した孔部に短管を固着し、該短管からポスト内へチエン部を通挿するととも に、該チエン部をポスト内の下部寄りで折り返し、他端部をポスト内の上部寄り で掛止し、かつ下部の折り返し部を滑動可能に掛止した掛止金具を、ポスト下端 部から伸びた引っ張りバネで下方へ引っ張るようにしてある。That is, in the chain lock mounting structure for a bicycle of the present invention, a short tube is fixed to a hole formed in a side portion of a seat post, and the chain section is inserted into the post from the short tube, and The chain is folded back near the bottom of the post, the other end is hooked near the upper part of the post, and the bottom folding part is slidably locked. I'm pulling it down.
【００４１】 そのため、イ）チエン錠を不使用時には、解錠した状態のチエン部は自動的に シートポスト内へ引っ張り込んで収納することができる。Therefore, a) when the chain lock is not used, the unlocked chain part can be automatically pulled into the seat post and stored.
【００４２】 ロ）チエン部は、ポスト内の下部寄りで折り返した状態に収納されるので、折 り返される分だけチエン部を収納可能な長さが長くなっており、チエン部は全長 を充分に引き込んで収納できる。(B) Since the chain part is stored in a folded state near the lower part of the post, the length of the chain part that can be stored is increased by the amount of the folded back part, and the chain part has a sufficient total length. Can be stored by pulling in.
【００４３】 ハ）同様にして、チエン部を充分に長いものにすることもでき、例えば前輪に 届く長さにして施錠して前輪を施錠し、前輪の盗難防止も同時に行える。(C) Similarly, the chain portion can be made sufficiently long, and for example, the front wheel can be prevented from being stolen at the same time by locking the front wheel by locking the front wheel so that it reaches the front wheel.
【００４４】 ニ）また、不使用時のチエン錠を荷籠その他に入れる手間が無くなるし、チエ ン部の他端部がポスト内に固定されているので、チエン錠の紛失や盗難に遇うこ とも無くなる。(D) Further, the time when the chain lock is not in use can be saved in a luggage basket or the like, and since the other end of the chain is fixed in the post, the chain lock can be prevented from being lost or stolen. It disappears.
【００４５】 ホ）さらに、チエン部をポスト内へ収納後は、錠部の一部が短筒から露出して いるだけで、すっきりして体裁が良い。(E) Further, after the chain portion is housed in the post, the lock portion is only exposed from the short cylinder, which is neat and has a good appearance.
【００４６】 ヘ）チエン錠を使用時には、シートポストからチエン部をそのまま引き出し、 後輪や地上の固定物に巻き掛けて錠部で施錠すればよく、荷籠等から取り出した り、巻き付けてあるポストから外す等の必要が無く、施錠を容易・迅速に行うこ とができる。F) When using the chain lock, pull out the chain part from the seat post as it is, wrap it around a rear wheel or a fixed object on the ground, and lock it with the lock part. It is taken out from the luggage basket or wound. Locking can be done easily and quickly without the need to remove it from the post.
