Description

【０００１】
【発明の属する技術分野】
本発明は、自動車の車輪に取付け、その走行を不可能にするタイプの車輌盗難防止装置に関する。
【０００２】
【従来の技術】
従来、車輌盗難防止装置の一例としては、車輪（タイヤ）のホイールをロックするタイプのものがある。しかし、ホイールをロックする車輌盗難防止装置は、タイヤホイールは盗まれないという利点があるものの、泥棒にとっては、何らかの手段でエンジンスイッチを「ＯＮ」にさえできれば、いとも簡単に「車ごと」持って行くことができる。
【０００３】
そこで、自動車の車輪に取付け、その走行を不可能にするタイプの車輌盗難防止装置が出現する。この車輪止め型車輌盗難防止装置の一例は、特開平７−１９７６９２号公報に記載されている。
【０００４】
ここで上記公報に記載された実施例の構成について簡単に説明する。この車輌盗難防止装置は、路面上に載置されかつ車輪の半径方向に伸縮自在に嵌合する前後一対の角パイプと、これらの角パイプにそれぞれ固定的に立設された一対の水平脚支持部材と、これらの水平脚支持部材にそれぞれ固定された逆Ｕ字型の車輪止め本体と、これら前後の車輪止め本体にラック、ピニオンの動力伝達機構を介して接続し、かつ、ピニオンと係合するラチェト爪、操作杆としての締めアームを有する締め具と、この締め具をロックする錠とから構成されている。
【０００５】
しかして、前記構成の車輌盗難防止装置は、まず前後一対の角パイプを適宜に嵌め合わせ、次に操作杆を操作して対向する前後の逆Ｕ字型の車輪止め本体を車輪の半径方向中心に向かって移動させ、最後に前後の車輪止め本体が一つの車輪を挟むように接合したならば、錠を適宜に施錠して締め具をロック状態にする。
【０００６】
しかしながら、上記構成にあっては、次に列挙するような問題点があった。
（１）構成する部品点数が多い。例えばアーム状車輪止め本体以外に、水平脚支持部材、前後一対の角パイプ、ラック、ピニオン等の動力伝達機構、操作杆を有する締め具など多数の部材を必要とする。
（２）自動車のトランクに収納するには「あまりにも立体的」であり、収納スペースが制約を受ける。
（３）左右の車輪をロックしようと思えば、それぞれにセットしなければならないので、時間がかかる。つまり、左右の車輪に対して手軽にセットすることができない。また、相当な重量があるので、運搬も容易ではない。
【０００７】
【発明が解決しようとする課題】
本発明は以上のような従来の問題点に鑑み、第１の目的は、構成する部品点数を少なくすることである。第２の目的は、多様の車種に対応して用いることができると共に、縮めてトランクに収納することができ、しかも収納した場合に於いて、極力収納スペースが制約を受けないことである。第３の目的は、左右の車輪に対して手軽にセットすることができることである。第４の目的は、防犯効果を高めることができることである。
【０００８】
【課題を解決するための手段】
本発明の車輌盗難防止装置は、嵌合部１２の一端部に一方の車輪ホイール５の被係合部７に係合する第１係合腕部１３を有する第１車輪止め係合体１１と、この第１車輪止め係合体１１の前記嵌合部に長さ方向に伸縮可能に摺嵌する棒状部３１に他方の車輪ホイール５の被係合部７に係合する第２係合腕部３２を有する第２車輪止め係合体３０と、前記第１車輪止め係合体１１に設けられた錠部１４に組込まれ、かつ、前記第１・第２係合腕部が左右の車輪の車輪ホイールに抱持状態にセッティングされた時に第１車輪止め係合体１１及び第２車輪止め係合体３０が互いに伸長しないようにロックする錠装置３とから成る。
【０００９】
また本発明の車輌盗難防止装置は、嵌合部１２Ａの一端部に一方の車輪ホイールの被係合部に係合する第１係合腕部を有する第１車輪止め係合体１１Ａと、この第１車輪止め係合体１１Ａの前記嵌合部に長さ方向に伸縮可能に摺嵌する棒状部３１Ａに他方の車輪ホイールの被係合部に係合する第２係合腕部を有する第２車輪止め係合体３０Ａと、前記第２車輪止め係合体３０Ａの棒状部３１Ａに形成された錠部１４Ａに組込まれ、かつ、前記第１・第２係合腕部が左右の車輪の車輪ホイールに抱持状態にセッティングされた時に第１車輪止め係合体１１Ａ及び第２車輪止め係合体３０Ａが互いに伸長しないようにロックする係合爪体２３Ａを備えた錠装置３Ａとから成る。
【００１０】
【発明の実施の形態】
図１乃至図９に示す第１実施例を用いて実施形態を説明する。まず１は、自動車の左右の車輪２を抱持した状態で錠装置３を施錠することができる車輪止め型車輌盗難防止装置である。自動車の車輪２は、周知のようにタイヤ４とホイール５とを有する。そして、ホイール５は、タイヤ幅に合わせたリム幅を有し、かつ、中心のホール（Ｐ．Ｃ．Ｄ）６を同心円とする適宜箇所には複数個の被係合部（任意形状の孔、空間など）７が形成されている。本発明は、車輪２の前記ホイール５の被係合部７を利用して左右の車輪２を抱持状態にロックし、これにより自動車の自走を不可能にする。そこで、次に車輌盗難防止装置１を構成する各部材について、区分けして詳しく説明する。
【００１１】
「第１車輪止め係合体１１」
棒状の第１車輪止め係合体１１は、パイプ状の嵌合部１２と、この嵌合部１２の一端部（図１を基準にるすと左端部）に鉤状に固設された第１の係合腕部１３と、この係合腕部１３とは反対側の前記嵌合部１２の他端部に形成された突起状錠部１４に組込まれた錠装置３とから成る。第１車輪止め係合体１１は、図９で示すように普通一般の自動車（例えば２，０００ＣＣの乗用車）ＶのトランクルームＴ内に収納することができるように所要の長さに設定されている。
【００１２】
「嵌合部１２」
嵌合部１２は、特に外壁の外観的な形態を問わないが、本実施例では長筒状の棒状に形成されている。しかして、１５は内周壁１２ａに長さ方向に形成された細長筋状の横溝で、この横溝１５は他端部の嵌合口１６から一端面まで直線状に形成されている。この横溝１５は、第１・第２車輪止め係合体１１，３０が互いに回転可能であっても良いので、必ずしも本発明の特定要件ではない。
【００１３】
「係合腕部１３」
第１の係合腕部１３は、この嵌合部１２の左端部の外壁にＬ型状に一体成形されている。係合腕部１３は嵌合部１２の径に比して短径で、例えば人差し指を折り曲げたような格好をしている。この係合腕部１３は、図１で示すように嵌合部１２の左端部から半径方向へ延びる細長状連杆部１３ａと、この連杆部１３ａの先端部を内側に略９０度折り曲げて形成した係合杆部１３ｂとから成り、前記係合杆部１３ｂは、一方のホイール５の前述した孔状被係合部７に係合する。
【００１４】
「錠部１４」
錠部１４には錠装置３が組込まれている、この錠装置３は、本実施例では図２、図３などで示すように、キー２０の操作によって回転する普通一般のシリンダー錠２１と、このシリンダー錠２１の回転式駆動体２２によって作動し、かつ、第２車輪止め係合体３０と係脱する係合爪体２３と、この係合爪体２３を係合方向へ常時付勢するバネ２４とを有する。図５及び図６は、錠部１４の内部構造の一例を示す。ここで図６を参照にすると、回転式駆動体２２は、その挿入側端面の偏心位置に、係合爪体２３の一つの切欠係合面２５と係合する駆動ピン２６を有している。係合爪体２３は、駆動ピン２６と対向する一側壁がチャンネル形状に切欠され、この切欠部２７内に前記駆動ピン２６が入り込んでいる。また係合爪体２３は、その係合側の先端部２８が爪状に形成されている。これは本実施例では第２車輪止め係合体３０の挿入部側外周壁に挿入方向に連続的に形成された複数個の環状係合歯（係合溝）が、全体としてラチエットであるためである。
【００１５】
「第２車輪止め係合体３０」
棒状の第２車輪止め係合体３０は、第１車輪止め係合体１１のパイプ状嵌合部１２に挿入される棒状部３１と、この棒状部３１の一端部（図３を基準にるすと右端部）に鉤状に固設された第２の係合腕部３２と、前記棒状部３１の他端部（図３を基準にすると挿入部側の左端部）に設けられた回転防止部材３３とから成る。この第２車輪止め係合体３０と第１車輪止め係合体１１は、相対的に伸縮動する。第２車輪止め係合体３０も、第１車輪止め係合体１１の長さを考慮して所要の長さに設定されている。
【００１６】
「棒状部３１」
第１車輪止め係合体１１に対する棒状部３１の長さは、本実施例では図８で示すように車輌盗難防止装置１の収納位置Ｃ１、左右の車輪２に対する係合施錠位置Ｃ２、左右の車輪２に対する係合解除取外し位置Ｃ３をそれぞれ考慮して設定されている。望ましくは係合解除取外し位置Ｃ３に於いて、棒状部３１が嵌合部１２から外れない長さにすべきである。なお、前述したように棒状部３１の挿入部側外周壁には、挿入端に至るまで連続的にラチエット形式の係合歯（係合溝）３４が形成されているので、容易に外れてしまうことはない。
【００１７】
「第２の係合腕部３２」
第２の係合腕３２は、第１車輪止め係合体１１の第１係合腕部１３と同一である。したがって、符号で簡単に説明して重複的説明を割愛する。３２ａは連杆部、３２ｂは他方のホイール５の被係合部７に係合する係合杆部である
「回転防止部材３３」
回転防止部材３３は、図３及び図４に示すように挿入先端部に形成された凹所３６に収納された付勢バネ３７と、この付勢バネ３７のバネ力によって常時嵌合部１２の横溝１５に係合するスライド係合片３８とから成る。
【００１８】
「作用」
上記構成に於いて、図９で示すように普通一般の乗用車ＶのトランクルームＴ内に収納する場合には、第１・第２車輪止め係合体１１，３０を互いに収縮状態にしておく。この場合、望ましくは第２車輪止め係合体３０の棒状部３１は、第１車輪止め係合体１１の嵌合部１２に略嵌入している。
【００１９】
さて、車輌盗難防止装置１を左右の車輪に装着しようとする場合、まずトランクルームＴから車輌盗難防止装置１を取出し、前輪か後輪に対するセッテイングの準備をする。この場合錠装置３が解錠状態であれば、係合爪体２３の爪２８は棒状部３１の係合歯３４から離れているので、例えば第２車輪止め係合体３０を図８で示す係合解除取外し位置Ｃ３まで引伸ばす。
【００２０】
次に図１に示すように車輌盗難防止装置１を左右の車輪２にセッテイングする場合には、第１車輪止め係合体１１の第１係合腕部１３の係合杆部１３ｂを一方のホイール５の被係合部７に係合し、次いで第２車輪止め係合体３０を押し込む。この場合第２車輪止め係合体３０のスライド係合片３８は第１車輪止め係合体１１の横溝１５に係合しているので、該第２車輪止め係合体３０の棒状部３１は、回転することなく第１車輪止め係合体１１の嵌合部１２に摺嵌されることになる。そして、錠装置３が仮施錠状態の時、図３の係合状態にある係合爪片２３は、棒状部３１が嵌合部１２に入るにしたがってワンピッチ毎に係合歯３４との係脱を繰り替えす。
【００２１】
次に第２車輪止め係合体３０を押し込んで行き、第２車輪止め係合体３０の第２係合腕部３２が他方のホイール５の被係合部７に係合し、その結果、車輌盗難防止装置１が左右の車輪２に対する係合施錠位置Ｃ２になったならば、キー２０を適宜に施錠方向へと回転し、錠装置３を仮施錠状態から本施錠状態にする。これにより、自動車の左右の車輪２，２は、車輌盗難防止装置１の左右の車輪止め係合体１１，３０により抱持状態にロックされる。
【００２２】
【実施例】
この欄では図１０乃至図１３に示す第２実施例について説明する。なお、第２実施例の説明にあたって、第１実施例と同一の部分には、同一又は同様の符合を付して重複する説明を省略する。
【００２３】
この第２実施例は、第１実施例の発明の目的と構成上の主要部がそれぞれ同一であり、当業者の立場から示した均等例の一つに過ぎない。そこで、以下、第１記実施例と主に異なる点について説明する。この第２実施例は、車輌盗難防止装置１Ａの左右の車輪止め係合体１１Ａ，３０Ａにそれぞれ細部的な設計変更を試みている。
【００２４】
そこで、まず車輪止め係合体１１Ａについて説明すると、（１）嵌合部１２Ａの内周壁に横溝を形成していない点、（２）前記嵌合部１２Ａの他端部の内周壁にラチェット形式の係合歯３４Ａを形成している点、（３）前記他端部に錠部を突出形成していない点がそれぞれ異なる。
【００２５】
次に車輪止め係合体３０Ａについて説明すると、（４）一部長筒状に形成された棒状部３１Ａに錠部１４Ａの役割を持たせている点、（５）前記棒状部３１Ａの長筒状部（錠部）１４Ａは、棒状部３１Ａの一端部から中実状の挿入端部４０に至るまで形成されている点、（６）錠装置３Ａは、長筒状部１４Ａの始端部に組込まれたシリンダー錠２１Ａと、細長い連結杆４１を介してシリンダー錠２１Ａに連結された回転式駆動体２２Ａと、この回転式駆動体２２Ａの駆動ピン２６Ａに連動する係合爪体２３Ａと、この係合爪体２３Ａを係合方向に付勢するバネ２４Ａとから成る点がそれぞれ異なる。
【００２６】
この第２実施例は、車輪止め係合体１１Ａ，３０が相互に周方向に回転する点を除き、その作用は第１実施例と同様である。
【００２７】
【発明の効果】
以上の説明から明らかなように、本発明にあっては、次に列挙するような効果がある。
（１）構成する部品点数が少ない。したがって、組立が容易である、安価に製作をすることができる等の利点がある。
（２）第１車輪止め係合体に第２車輪止め係合体が長さ方向に伸縮可能に摺嵌するので、多様な車種に対応することができる。また、実施例によっては、自動車のトランクに収縮状態で収納することができる。
（３）左右の車輪に対して手軽にセットすることができる。
（４）左右の車輪を抱持状態にロックすることができるから、防犯効果を高めることができる。
（５）なお、車輌盗難防止装置が、第１車輪止め係合体１１及び第２車輪止め係合体３０が互いに周方向に回転するのを防止することができる回転防止部材３３を有している実施例の場合には、車輪ホイールの被係合部７に対する係合腕部の位置合わせが容易である。

BACKGROUND OF THE INVENTION
The present invention relates to a vehicle antitheft device which is attached to a wheel of an automobile and makes its running impossible.
[0002]
[Prior art]
Conventionally, as an example of a vehicle antitheft device, there is a type that locks a wheel of a wheel (tire). However, the vehicle anti-theft device that locks the wheel has the advantage that the tire wheel is not stolen, but for the thief, it is very easy to hold “every car” as long as the engine switch can be turned “ON” by some means. can go.
[0003]
Therefore, a vehicle antitheft device of the type that attaches to the wheel of an automobile and makes its running impossible appears. An example of this wheel stop type vehicle antitheft device is described in Japanese Patent Application Laid-Open No. 7-197692.
[0004]
Here, the configuration of the embodiment described in the above publication will be briefly described. The vehicle antitheft device includes a pair of front and rear square pipes that are placed on a road surface and that are telescopically fitted in a radial direction of a wheel, and a pair of horizontal legs that are fixedly erected on the square pipes. Members, inverted U-shaped wheel stopper main bodies fixed to these horizontal leg support members, and the front and rear wheel stopper main bodies connected to each other through a power transmission mechanism of a rack and a pinion, and engaged with the pinion. A ratchet pawl, a fastener having a fastening arm as an operating rod, and a lock for locking the fastener.
[0005]
Thus, the vehicle anti-theft device having the above-described configuration first fits a pair of front and rear square pipes as appropriate, and then operates the operating rod to connect the front and rear inverted U-shaped wheel stopper bodies to the center in the radial direction of the wheel. When the front and rear wheel stopper main bodies are joined so as to sandwich one wheel, the lock is appropriately locked to lock the fastener.
[0006]
However, the above configuration has the following problems.
(1) A large number of parts are configured. For example, in addition to the arm-shaped wheel stopper main body, many members such as a horizontal leg support member, a pair of front and rear square pipes, a power transmission mechanism such as a rack and a pinion, and a fastener having an operating rod are required.
(2) It is “too three-dimensional” to be stored in the trunk of an automobile, and storage space is restricted.
(3) If you want to lock the left and right wheels, it will take time because they must be set to each. That is, it cannot be easily set to the left and right wheels. Moreover, since there is considerable weight, transportation is not easy.
[0007]
[Problems to be solved by the invention]
In view of the conventional problems as described above, the first object is to reduce the number of components. The second object is that it can be used corresponding to various types of vehicles and can be shrunk and stored in the trunk, and when it is stored, the storage space is not restricted as much as possible. The third purpose is to be able to easily set the left and right wheels. The fourth purpose is to increase the crime prevention effect.
[0008]
[Means for Solving the Problems]
The vehicle antitheft device of the present invention includes a first wheel stopper engaging body 11 having a first engaging arm portion 13 that engages with an engaged portion 7 of one wheel 5 at one end of the fitting portion 12; A second engaging arm portion 32 that engages with the engaged portion 7 of the other wheel wheel 5 is engaged with the rod-like portion 31 that is slidably fitted in the fitting portion of the first wheel stop engaging body 11 in the longitudinal direction. The second wheel stopper engaging body 30 having the above-described structure and the lock portion 14 provided in the first wheel stopper engaging body 11 are incorporated into the wheel wheels of the left and right wheels. It comprises a locking device 3 that locks the first wheel stopper engaging body 11 and the second wheel stopper engaging body 30 so as not to extend each other when set in the holding state.

Desirably, the length should be such that the rod-like portion 31 does not come off the fitting portion 12 at the disengagement release position C3. As described above, since the ratchet type engagement teeth (engagement grooves) 34 are continuously formed on the insertion portion side outer peripheral wall of the rod-shaped portion 31 up to the insertion end, it is easily detached. There is nothing.
[0017]
"Second engagement arm 32"
The second engagement arm 32 is the same as the first engagement arm portion 13 of the first wheel stop engagement body 11. Therefore, it will be briefly described with reference numerals and redundant description will be omitted. Reference numeral 32 a denotes a linkage part, and 32 b denotes an engagement prevention part 33 that engages with the engaged part 7 of the other wheel 5.
As shown in FIGS. 3 and 4, the rotation preventing member 33 includes an urging spring 37 housed in a recess 36 formed at the insertion tip, and the spring force of the urging spring 37 constantly The slide engaging piece 38 is engaged with the lateral groove 15.
[0018]
