Description

【０００１】
【発明の属する技術分野】
本発明は、多重素子ピンを用いたシリンダー錠の複数ピン型上ピンに係り、特に、シリンダー錠の組み替え作業を楽に行い得るとともに、ピッキングなどの不正解錠の防止に効果のある複数ピン型上ピンに関するものである。
【０００２】
【従来の技術】
通常、シリンダー錠の上ピンは、内筒プラグと外筒との境目(シャーライン)に位置するようにバネ応力との組み合わせにより位置づけられている。多重素子ピンを下ピンに用いた場合にも同様であり、特殊な構造の上ピン、例えば公知の上ピン（特許第６５６６８４４号）を用いた場合でさえもバネ応力により内筒プラグが回転しないよう上ピンにより阻止されている。
しかしながら、このようなシリンダー錠の組み替えを行う場合、上ピンを外筒に保持するよう、内筒ホルダー等の工具を用いて上ピンが出て来ないように注意する必要があった。また、万がー、上ピンが飛び出てしまった場合、バネと上ピンを元の外筒に収めるには熟練を要した。
一方、多重素子ピンを用いたシリンダー錠といえども、特殊な工具を用いたり、ピッキング等の手段による不正解錠を完全に阻止することは困難であった。
【０００３】
【発明が解決しようとする課題】
本発明は、上記した実状に鑑みてなされたもので、シリンダー錠の外筒内に配設されるケーシングに、内筒プラグ内の多重素子ピンに対応した複数ピンと、該複数ピンを付勢する圧縮バネとを一体的に内蔵させることにより、内筒プラグを抜いても外筒から上ピンが飛び出ないようにし、シリンダー錠の組み替え作業を楽に行い得るシリンダー錠の複数ピン型上ピンを提供することをその目的とするものである。
また、本発明は、多重素子ピンを用いた耐ピッキング性能を飛躍的に向上させ、上ピンの新しい機能を生み出すことを目的に、多重素子ピン用の上ピンに用いられる前記複数ピン型上ピンあるいは公知の上ピンをそのまま利用することにより、デッドロックがかかる仕組みを構築するシリンダー錠を提供することをその目的とするものである。
さらに、多重素子ピン用の上ピンに用いられる前記複数ピン型上ピンを構成するハウジング形状をＨ型にすることにより、耐ピッキング性能を飛躍的に向上させたシリンダー錠の複数ピン型上ピンを提供することをその目的とするものである。
【０００４】
【問題を解決するための手段】
本発明に係るシリンダー錠の複数ピン型上ピンは、シリンダー錠の外筒内に配設されるケーシングと、内筒プラグ内の多重素子ピンすなわち中核下ピン、外殻下ピンに対応した複数ピンすなわち中核上ピン、外殻上ピンと、上記ケーシング内に配され一端が前記複数ピンと一体的に配されている複数ピン付勢バネとを備え、ケーシング開放部より内方に突成された突縁の内径が、上記ケーシング内にある外殻上ピン上部より外方に突成された突縁の外径より小さくしてなるとともに、ケーシング外周面とシリンダー錠外筒内周面とにそれぞれネジ部を設けて螺合自在としてなるものである。
【０００５】
【作用】
以下、本発明の作用について説明する。本発明に係るシリンダー錠の複数ピン型上ピンは、シリンダー錠の外筒内に配設されるケーシングと、内筒プラグ内の多重素子ピンすなわち中核下ピン、外殻下ピンに対応した複数ピンすなわち中核上ピン、外殻上ピンと、上記ケーシング内に配され一端が前記複数ピンと一体的に配されている複数ピン付勢バネとを備え、ケーシング開放部より内方に突成された内突縁の内径が、上記ケーシング内にある外殻上ピン上部より外方に突成された外突縁の外径より小さくしてなるので、シリンダー錠の組み替え作業の際に、内筒プラグを抜いても外筒から上ピンが飛び出ないから、シリンダー錠の組み替え作業を楽に行い得ることとなる。そして、シリンダー錠の外筒プラグ内にケーシングを配設する手段として、複数ピン型上ピンを構成するハウジングの外周面と、シリンダー錠の外筒プラグ内周面とにそれぞれネジ部を設けて、螺合自在とすれば、シリンダー錠の外筒プラグ内に複数ピン型上ピンを簡単かつ容易に螺合固着できる。また、本発明に係るシリンダー錠は、上ピンが凸構造を持つとともに、シリンダー内筒プラグに上ピンの凸構造が落ちるアンチピッキング溝を設け、さらに中間ピンが存在することによってシャーラインが上下２箇所にできるため、ピッキングが困難になる上、特殊な工具を用いたり、ピッキング等の手段によって、不正なシャーラインで内筒プラグを回すと、アンチピッキング溝に上ピンの中核上ピンが落ち込んで、デッドロックがかかり不正解錠が完全に阻止されることとなる。さらにまた、本発明に係るシリンダー錠の複数ピン型上ピンは、ハウジング形状をＨ型にすることにより、ピッキングなどの不正解錠を行うために内筒プラグにテンションを掛けると、内筒と外筒の境目（シャーライン）にずれが生じ、このずれの部分にＨ型の突起がぶつかることによって、上ピンを上がり難くするものである。
【０００６】
【実施例】
以下、本発明について、実施例に基づき説明する。図１は本発明に係るシリンダー錠の複数ピン型上ピンを示す概略断面図である。図２は上記複数ピン型上ピンを外筒に固着した状態を示す概略断面図、図３は上記複数ピン型上ピンが通常の上ピンとして作用する場合のシャーライン形成状態を示す概略断面図、図４は上記複数ピン型上ピンがアンチピッキングピンとして作用する場合のシャーライン形成状態を示す概略断面図、図５は上記複数ピン型上ピンを使用したシリンダー錠の分解斜視図である。図において、本発明に係るシリンダー錠の複数ピン型上ピン１は、シリンダー錠内筒２の外筒３内に配設されるケーシング４に、内筒プラグ５内の多重素子ピン（中核下ピン６、外殻下ピン７）に対応した複数ピン（中核上ピン８、外殻上ピン９）と、該複数ピンを付勢する圧縮バネ10とを一体的に内蔵させてなる。さらに詳しくは、内筒プラグ内の多重素子ピンすなわち中核下ピン、外殻下ピンに対応した複数ピンすなわち中核上ピン、外殻上ピンと、上記ケーシング内に配され一端が前記複数ピンと一体的に配されている複数ピン付勢バネとを備え、ケーシング開放部より内方に突成された内突縁の内径が、上記ケーシング内にある外殻上ピン上部より外方に突成された外突縁の外径より小さくしている。
また、ケーシング４の外周面11と、シリンダー錠の外筒３の内周面12とにそれぞれネジ部13,14を設けて、螺合自在としている。15は円盤型中間ピン、15’はドーナツ型中間ピンである。したがって、一体型の複数ピン型を用いることにより、複数ピン型上ピン１はシリンダー錠の組み替え作業の際に、内筒プラグを抜いても外筒から上ピン（中核上ピン８、外殻上ピン９）が飛び出ないから、シリンダー錠の組み替え作業を楽に行なうことができ、また、ケーシング４と外筒３とにそれぞれ対応するネジ部を設けたから、外筒３内に複数ピン型上ピン１を簡単かつ容易に螺合固着できる。また、上記中核上ピン８は凸構造16を持ち、シリンダー内筒プラグ５に設けられたアンチピッキング溝17に落ちる構成とされ、これによって、特殊な工具を用いたり、ピッキング等の手段による不正解錠が完全に阻止されることとなる。ここで、中間ピンの形状は、穴の空いていない円盤型であっても、ドーナツ型であっても、中核上ピン８の凸構造16が正常なシャーライン形成時にアンチピッキング溝17に落ち込むことを防ぐ形状であればよく、穴の有無は本機能に係らないが、本来の多重素子ピンの機能を考慮するならば、ドーナツ型である方が好ましい。以下、本発明の使用の実際を、図５から図10に示す説明図に従って示す。図６は施錠状態を示し、図７および図は８正常なシャーライン形成状態で内筒プラグ５が回動する状態を示す。通常、純正キー（合鍵）を挿入した場合、図５に示す正常なシャーラインが形成され、図７ないし図８に示した多重素子ピン（中核下ピン６、外殻下ピン７）と中間ピン15との境界で内筒プラグが回動する。図９および図10は不正なシャーライン形成状態で内筒プラグ５が回動すると、中核上ピン８の凸構造16がシリンダー内筒プラグ５に設けられたアンチピッキング溝17に落ちて、内筒プラグ５の回動が停止される状態を示している。

以下、本発明の使用の実際を、図12から図16に示す説明図に従って示す。
図12は施錠状態を示し、図13および図14は正常なシャーライン形成状態で内筒プラグ22が回動する状態を示す。通常、純正キー（合鍵）を挿入した場合、図11に示す正常なシャーラインが形成され、図13ないし図14に示した多重素子ピン（中核下ピン28、外殻下ピン29）と中間ピン27との境界で内筒プラグが回動する。図15および図16のごとく不正なシャーライン形成状態で内筒プラグ22が回動すると、中核上ピン21の凸構造24がシリンダー内筒プラグ22に設けられたアンチピッキング溝23に落ちて、内筒プラグ22の回動が停止される状態を示している。

図17から図20は、本発明に係るシリンダー錠の複数ピン型上ピンの別の実施例を示し、 図17は、耐ピッキング性能を向上させた本発明に係るシリンダー錠の複数ピン型上ピンの形状をＨ型にした状態を示す概略断面図である。図18は上記複数ピン型上ピンを外筒に備え、多重素子ピン（中核下ピン39、外殻下ピン40を内筒に挿入した状態を示す概略断面図、図19は不正解錠を試みようとして上記複数ピン型上ピンに回転応力（テンション）を掛けた状態、図20はテンションを掛けた状態で、不正解錠を試みようと外殻下ピンを押し上げた状態を示す概略断面図である。
図18において、本発明に係るシリンダー錠の複数ピン型上ピン31は、シリンダー錠外筒36内に圧縮バネ38とともに配設され、内筒37に内設された多重素子ピン（中核下ピン39、外殻下ピン40）にバネ圧をかけている。この状態で内筒に回転応力（テンション）を掛けると、図19に示すごとく内筒がずれて、複数ピン型上ピン31の突起部32及び突起部33が外筒および内筒の壁面に密接した状態で傾いて止まる。この状態で、ピックと呼ばれるピッキング工具などにより外殻下ピン40を押し上げると、図20に示すごとく複数ピン型上ピン31の突起部33が、外筒がずれて生じた先端41に引っかかるため、複数ピン型上ピン31が外筒36内に収まらなくなり、結果ピッキングが出来ないことになる。

BACKGROUND OF THE INVENTION
The present invention relates to a multi-pin type upper pin of a cylinder lock using a multi-element pin, and in particular, it is possible to easily reassemble a cylinder lock and to effectively prevent unauthorized unlocking such as picking. It is about pins.
[0002]
[Prior art]
Usually, the upper pin of the cylinder lock is positioned by a combination with spring stress so as to be positioned at the boundary (shear line) between the inner cylinder plug and the outer cylinder. The same applies to the case where the multi-element pin is used as the lower pin, and even when an upper pin having a special structure, for example, a known upper pin (Japanese Patent No. 6656844) is used, the inner cylinder plug does not rotate due to the spring stress. It is blocked by the upper pin.
However, when such a cylinder lock is changed, it is necessary to be careful that the upper pin does not come out using a tool such as an inner cylinder holder so that the upper pin is held in the outer cylinder. Also, if the upper pin pops out, it took skill to fit the spring and upper pin into the original outer cylinder.
On the other hand, even with a cylinder lock using multi-element pins, it has been difficult to completely prevent unauthorized unlocking by using a special tool or by means such as picking.
[0003]
[Problems to be solved by the invention]
The present invention has been made in view of the above situation, and a plurality of pins corresponding to multiple element pins in an inner cylinder plug and a plurality of pins are urged to a casing disposed in the outer cylinder of the cylinder lock. By providing a built-in compression spring, the upper pin does not pop out of the outer cylinder even if the inner cylinder plug is pulled out, and a multi-pin type upper pin for a cylinder lock that can be easily reassembled is provided. For that purpose.
The present invention also provides the multi-pin type upper pin used for an upper pin for a multi-element pin for the purpose of dramatically improving picking resistance using the multi-element pin and creating a new function of the upper pin. Alternatively, it is an object of the present invention to provide a cylinder lock for constructing a mechanism that causes a deadlock by using a known upper pin as it is.
Furthermore, the multi-pin type upper pin of the cylinder lock which has dramatically improved picking resistance performance by making the shape of the housing constituting the multi-pin type upper pin used for the upper pin for multi-element pins into H type Its purpose is to provide.
[0004]
[Means for solving problems]
The multi-pin type upper pin of the cylinder lock according to the present invention includes a casing disposed in the outer cylinder of the cylinder lock, a multi-element pin in the inner cylinder plug, that is, a plurality of pins corresponding to the core lower pin and the outer shell lower pin. That is, a projecting edge that protrudes inward from the casing opening portion, comprising a core upper pin, an outer shell upper pin, and a multi-pin biasing spring that is disposed in the casing and has one end disposed integrally with the multi-pin. The inner diameter of the casing is smaller than the outer diameter of the protruding edge protruding outward from the upper part of the outer shell upper pin in the casing, and the threaded portion is respectively formed on the outer peripheral surface of the casing and the inner peripheral surface of the cylinder lock outer cylinder. And can be screwed together.
[0005]
[Action]
The operation of the present invention will be described below. The multi-pin type upper pin of the cylinder lock according to the present invention includes a casing disposed in the outer cylinder of the cylinder lock, a multi-element pin in the inner cylinder plug, that is, a plurality of pins corresponding to the core lower pin and the outer shell lower pin. In other words, an inner protrusion that protrudes inward from the casing opening portion includes a core upper pin, an outer shell upper pin, and a plurality of pin urging springs arranged in the casing and having one end arranged integrally with the plurality of pins. Since the inner diameter of the edge is smaller than the outer diameter of the outer protruding edge protruding outward from the upper part of the outer shell upper pin in the casing , the inner cylinder plug is pulled out when reassembling the cylinder lock. However, since the upper pin does not pop out from the outer cylinder, the cylinder lock can be easily reassembled. Then, as means for disposing the casing in the outer cylinder plug of the cylinder lock, a screw portion is provided on each of the outer peripheral surface of the housing constituting the multi-pin type upper pin and the inner peripheral surface of the outer cylinder plug of the cylinder lock, If it can be screwed, a multi-pin type upper pin can be screwed and fixed easily in the outer cylinder plug of the cylinder lock. In the cylinder lock according to the present invention, the upper pin has a convex structure, the cylinder inner plug is provided with an anti-picking groove in which the convex structure of the upper pin falls, and the presence of the intermediate pin causes the shear line to move up and down. This makes it difficult to pick, and if you use a special tool or rotate the inner cylinder plug with an illegal shear line by means such as picking, the core upper pin of the upper pin falls into the anti-picking groove. Therefore, deadlock occurs and illegal unlocking is completely prevented. Furthermore, the multi-pin type upper pin of the cylinder lock according to the present invention has an H-shaped housing shape, so that when the inner cylinder plug is tensioned to perform illegal unlocking such as picking, A shift occurs at the boundary (shear line) of the cylinder, and an H-shaped protrusion collides with the shift, thereby making it difficult to raise the upper pin.
[0006]
