Description
本発明はシリンダー錠及びシリンダー錠用の鍵に関し、特に錠本体と鍵本体との結合から成るシリンダー錠及びシリンダー錠用の鍵に関する。 The present invention relates to a cylinder lock and a key for a cylinder lock , and more particularly to a cylinder lock and a key for a cylinder lock formed by coupling a lock body and a key body.
特許文献１は、鍵穴に対する挿入時における合鍵の操作性を考慮し、鍵（キー）側の工夫を施したものである。また特許文献２も、特許文献１と同様である。したがって、鍵（キー）が、摘み部分と、該摘み部分に回動可能に設けられたブレードとから成る事項は、既に公知である。 Japanese Patent Application Laid-Open No. H10-228707 has a key (key) side contrivance in consideration of the operability of a combined key at the time of insertion into a keyhole. Patent Document 2 is the same as Patent Document 1. Therefore, the matter in which the key (key) is composed of a knob portion and a blade rotatably provided on the knob portion is already known.
さらに、特許文献３は、バリヤーフリーの観点から、キーを指で押し込むことにより、錠前を容易に解錠することを目的とした錠前用キー挿入補助具が開示され、該キー挿入補助具のパイプ状連結体の先端部には、錠本体の内筒の前面に設けた第１磁性体の極性に対応して吸着する第２磁性体を設ける事項が記載されている。 Furthermore, Patent Document 3 discloses a key insertion assisting tool for a lock for the purpose of easily unlocking the lock by pushing the key with a finger from the viewpoint of barrier free, and a pipe for the key insertion assisting tool. In the distal end portion of the connecting body, there is described a matter of providing a second magnetic body that adsorbs corresponding to the polarity of the first magnetic body provided on the front surface of the inner cylinder of the lock body.
ところで、普通一般に建具用の合鍵は、摘み部分と、該摘み部分の先端部に連設する長板状ブレードから成り、前記長板状ブレードの側面又は／及び平坦面には刻みや窪み（キーコード）が形成されている。周知のように、長板状ブレードを有する合鍵には、錠本体に組み込まれた可動障害子（タンブラー）と整合する位置に前記キーコードを有し、合鍵を反転しても使用することができるタイプ（リバーシブル機能）が存在している。このような背景技術の基で、合鍵挿入時の利便性を図るために、現在、合鍵のリバーシブル機能をより一層高める試みが検討されている。 By the way, generally a joint key for joinery is composed of a knob part and a long plate-like blade connected to the tip part of the knob part, and the side or / and flat surface of the long plate blade has a notch or a depression (key). Code) is formed. As is well known, a key having a long plate blade has the key code at a position aligned with a movable obturator (tumbler) incorporated in the lock body, and can be used even if the key is reversed. A type (reversible function) exists. Based on this background art, attempts are being made to further increase the reversible function of the combined key in order to improve convenience when inserting the combined key.
さて、合鍵挿入時の利便性を考慮すると、ブレードの外周面の形状が「３回転対称以上」のものが望ましい。例えば正三角形は３回転対称、正四角形は４回転対称であるが、例えば五角形から六角形、六角形から八角形という具合に角数が増えて行くと、最終的には、ブレードの外形或いは断面形状が真円の状態となる。真円の場合には、ブレードの表も裏もないことから、３６０度の「どの回転角度」であっても、鍵穴が真円或いは余裕（間隙）のある多角形穴であれば、ブレードを鍵穴に自由に差込むことができる。 Now, considering the convenience at the time of inserting the key, it is desirable that the shape of the outer peripheral surface of the blade is “three or more rotational symmetry”. For example, a regular triangle is three-fold symmetric and a regular square is four-fold symmetric. However, when the number of angles increases, for example, from pentagon to hexagon, from hexagon to octagon, the final shape or cross section of the blade The shape is a perfect circle. In the case of a perfect circle, there is neither the front nor the back of the blade. Therefore, if the keyhole is a perfect circle or a polygonal hole with a margin (gap) at any rotation angle of 360 degrees, Can be freely inserted into the keyhole.
しかしながら、合鍵挿入時の利便性を可能な限り追及すると、合鍵のブレードが鍵穴内で空回りするという問題点がある。また合鍵挿入時の利便性を考慮する場合に於いて、錠側に工夫を施して挿入時の操作性の向上を図ることが期待されている。特に、バリヤーフリーの観点から、内筒の鍵穴に対する合鍵のブレードの挿入角度が多少大雑把であっても、容易にブレードの先端部を鍵穴に嵌め合せることができる錠前が要望されている。なお、この明細書では、錠前は「錠本体」を意味し、合鍵は「鍵本体」を意味する。そして、「シリンダー錠」は、両者を含む概念である。 However, if the convenience at the time of inserting the key is pursued as much as possible, there is a problem that the blade of the key is idle in the keyhole. In addition, when considering the convenience when inserting a key, it is expected to improve the operability during insertion by devising the lock side. In particular, from the viewpoint of barrier-free, there is a demand for a lock that can easily fit the tip of the blade into the keyhole even if the insertion angle of the keyed blade with respect to the keyhole of the inner cylinder is somewhat rough. In this specification, the lock means “lock body”, and the combined key means “key body”. “Cylinder lock” is a concept that includes both.
本発明の第１の目的は、鍵本体の挿入時の利便性を可能な限り追及することである。本発明の第２の目的は、鍵本体のブレードが内筒の鍵穴内で空回りする実施形態の場合であっても、内筒を施・解錠方向へ回転させることができることである。本発明の第３の目的は、鍵本体の摘み部分とブレードとが相対回転可能に設けられている実施形態の場合であっても、内筒を施・解錠方向へ回転させることができることである。本発明の第４の目的は、鍵違いの数を飛躍的に増大させることができると同時に、複製が困難なキー（シリンダー錠用の鍵）を得ることである。 The first object of the present invention is to pursue as much convenience as possible when inserting a key body. The second object of the present invention is that the inner cylinder can be rotated in the locking / unlocking direction even in the embodiment in which the blade of the key body is idle in the key hole of the inner cylinder. The third object of the present invention is that the inner cylinder can be rotated in the locking / unlocking direction even in the embodiment in which the knob portion of the key body and the blade are provided so as to be relatively rotatable. is there. The fourth object of the present invention is to obtain a key (cylinder lock key) that can dramatically increase the number of key differences and is difficult to duplicate.

図１乃至図１４は、本発明の第１実施形態の各説明図である。図１はシリンダー錠の錠前Ｘ（以下、「錠本体Ｘ」という。）と合鍵（以下、ここでは「鍵本体Ｙ」とう。）を示す斜視図である。ここで、まず、鍵本体Ｙの構成を簡単に説明する。鍵本体Ｙは、摘み部分１と、該摘み部分１に固定又は回転可能に設けられた長柱状のブレード（ここでは「キー軸後端部」も含む）２とから成る。実施形態では、図５及び図６で示すように、鍵本体Ｙは、長筒状の摘み部分１と、この長筒状摘み部分１に鍔部分からのキー軸後端部２ｂが挿嵌する小刀状のブレード２と、このブレード２のキー軸後端部２ｂを摘み部分１の後端部の凹所に連結する鋲形態の支承具４とから成る。付言すると、摘み部分１とブレード２は相回転可能に結合している。 1 to 14 are explanatory views of the first embodiment of the present invention. FIG. 1 is a perspective view showing a lock X (hereinafter referred to as “lock body X”) and a key (hereinafter referred to as “key body Y”) of a cylinder lock. Here, first, the configuration of the key body Y will be briefly described. The key body Y includes a knob portion 1 and a long columnar blade (including a “key shaft rear end portion” here) 2 that is fixed or rotatable to the knob portion 1. In the embodiment, as shown in FIGS. 5 and 6, the key body Y includes a long cylindrical knob portion 1 and a key shaft rear end portion 2 b from the collar portion is inserted into the long cylindrical knob portion 1. The blade 2 is composed of a blade-like blade 2 and a hook-shaped support 4 that connects the rear end 2b of the key shaft of the blade 2 to the recess of the rear end of the knob 1. If it adds, the knob | pick part 1 and the braid | blade 2 are couple | bonded so that a phase rotation is possible.
前記ブレードの鍔部分から先の角柱状先端部の外周面（ブレード−本体部分）には、例えば４回転対称となる位置に窪み３が形成されている。前記窪み３はキーコードの一例であり、説明の便宜上簡略的に説明している。 On the outer peripheral surface (blade-main body portion) of the tip of the prism after the flange portion of the blade, for example, a recess 3 is formed at a position that is four-fold symmetrical. The recess 3 is an example of a key code and is simply described for convenience of description.
キーコード３は、３回転対称以上であれば各側面に形成された大小の刻みや窪みであっても良いことから、実施形態のキーコード３は、開口が大きくて凹所が深い窪み３ａと、開口が小さくて凹所が浅い窪み３ｂとから成る（図２、図５、図６参照）。 Since the key code 3 may be large or small indentations and depressions formed on each side surface as long as it is three or more rotationally symmetric, the key code 3 of the embodiment has a depression 3a having a large opening and a deep recess. And a recess 3b having a small opening and a shallow recess (see FIGS. 2, 5, and 6).
また実施形態の合鍵Ｙのブレード２は、その垂直断面の形状が八角形であり（図４参照）、垂直断面の横幅Ｋ１と縦幅Ｋ２が略同一である（図９参照）。このように本発明の合鍵Ｙのブレード２の外周形状は円形状又は３回転対称以上の多角形状のいずれかに形成されている。 Further, the blade 2 of the key Y of the embodiment has an octagonal shape in the vertical cross section (see FIG. 4), and the vertical width K1 and the vertical width K2 are substantially the same (see FIG. 9). Thus, the outer peripheral shape of the blade 2 of the key Y of the present invention is formed in either a circular shape or a polygonal shape with three or more rotational symmetry.
これに対して、鍵穴の内周面も前記ブレードを受け入れる円形状又は多角形状のいずれかに形成されている。そして、例えば鍵穴１３の内周面は、前記ブレード２の外周形状に対応するように多角形状に形成されていると共に、多角形状のブレード２の外周面と鍵穴１３の内周面との間には適宜に間隙が設定されている。 On the other hand, the inner peripheral surface of the keyhole is also formed in either a circular shape or a polygonal shape that receives the blade. For example, the inner peripheral surface of the keyhole 13 is formed in a polygonal shape so as to correspond to the outer peripheral shape of the blade 2, and between the outer peripheral surface of the polygonal blade 2 and the inner peripheral surface of the keyhole 13. The gap is set appropriately.
ところで、前述したように、実施形態の合鍵Ｙの摘み部分１とブレード２は、互いに回転可能に結合している。したがって、ブレード２を鍵穴１３に差込んだとしても、ブレード２がそのまま停止状態で摘み部分１だけが空回り状態となる。
そこで、摘み部分１からの操作力を内筒に伝達する伝達手段が必要となることから、色々な実施形態の結合手段を設けている。
By the way, as described above, the knob portion 1 of the joint key Y and the blade 2 of the embodiment are coupled to each other so as to be rotatable. Therefore, even if the blade 2 is inserted into the keyhole 13, the blade 2 is still stopped and only the knob portion 1 is idle.
Therefore, since transmission means for transmitting the operating force from the knob portion 1 to the inner cylinder is required, coupling means of various embodiments are provided.
すなわち、実施形態では、鍵本体Ｙを錠本体Ｘの鍵穴１３に差込んだ時、内筒１２と鍵本体Ｙが共働する結合手段５を該内筒１２の前部と該鍵本体Ｙの摘み部分１の先端部に設けている。 That is, in the embodiment, when the key body Y is inserted into the key hole 13 of the lock body X, the coupling means 5 in which the inner cylinder 12 and the key body Y work together is connected to the front portion of the inner cylinder 12 and the key body Y. It is provided at the tip of the knob portion 1.
しかして、第１実施形態の結合手段５は、図２、図３、図４等で示すように、内筒１２の前部６に設けられた第１係合部分７と、摘み部分１の先端部８に設けられた第２係合部分９とから成り、前記第１係合部分７は、周方向に所定間隔を有して形成された複数（例えば４個）の係合凹所であり、一方、前記第２係合部分９は、先端部８の周方向に所定間隔を有して形成された複数（例えば４個）の係合突起である。 Therefore, the coupling means 5 of the first embodiment includes the first engaging portion 7 provided on the front portion 6 of the inner cylinder 12 and the knob portion 1 as shown in FIGS. The first engaging portion 7 is a plurality of (for example, four) engaging recesses formed at predetermined intervals in the circumferential direction. On the other hand, the second engaging portion 9 is a plurality of (for example, four) engaging protrusions formed at a predetermined interval in the circumferential direction of the distal end portion 8.
次に、図２、図３及び図４を参照にして、本実施形態の錠本体Ｘを説明する。実施形態の錠本体Ｘも、鍵本体Ｙのブレード２を内筒１２の鍵穴１３に完全に差し込んだ時、ブレード２に形成されたキーコード３としての窪みや刻みと内筒１２の回転軸（例えばテールピース）Ｏと直交する軸直角断面上に位置するダンブラー２０とが一致するシリンダー錠である点で、従来の錠前と基本的な構造は変わらない。 Next, the lock body X of the present embodiment will be described with reference to FIGS. 2, 3, and 4. In the lock body X of the embodiment, when the blade 2 of the key body Y is completely inserted into the key hole 13 of the inner cylinder 12, the recess or notch as the key code 3 formed in the blade 2 and the rotation axis of the inner cylinder 12 ( For example, the basic structure is the same as that of a conventional lock in that the drum lock 20 located on the cross section perpendicular to the axis orthogonal to the tailpiece O is a cylinder lock.
しかしながら、本発明の第１実施形態は、鍵穴１３に対するブレードの挿入角度が多少大雑把であっても、ブレード２の先端部２ａが鍵穴１３の先端部の内周壁に形成された外拡状案内面１３ａに誘導された後、鍵本体Ｙを鍵穴１３の奥まで完全に差し込むことができる。したがって、前記外拡状案内面１３ａは、鍵穴１３の先端挿入口の縁部分ａから鍵穴本体１３Ｂの受入口の縁部分ｂに至るにしたがって、次第に左右・上下の幅が狭くなっている。 However, in the first embodiment of the present invention, even if the insertion angle of the blade with respect to the keyhole 13 is somewhat rough, the outer expanding guide surface in which the tip 2a of the blade 2 is formed on the inner peripheral wall of the tip of the keyhole 13 After being guided to 13 a, the key body Y can be completely inserted into the keyhole 13. Accordingly, the width of the outer expanded guide surface 13a gradually decreases from the edge portion a of the distal end insertion opening of the keyhole 13 to the edge portion b of the receiving hole of the keyhole body 13B.
しかして、図１０で示すように、鍵穴１３は、先端部の内周壁に外拡状案内面１３ａを有する誘導穴１３Ａと、この誘導穴１３Ａの後端に直ぐに或いは多少離間して連通する鍵穴本体１３Ｂとから成り、鍵穴１３の先端挿入口の縁部分ａの少なくとも左右・上下の内径（幅）Ｗ１、Ｗ２は、鍵本体Ｙのブレード２の先端部２ａの左右・上下の外径（幅）Ｋ１、Ｋ２よりも大きい。また、前記先端挿入口の縁部分ａよりも奥に相当する先端部又は中央部のいずれかに前記ブレード２をキーコード３とダンブラー２０とが一致する位置へと受け入れる前記鍵穴本体１３Ｂが設けられている。 Thus, as shown in FIG. 10, the keyhole 13 includes a guide hole 13A having an outer expanding guide surface 13a on the inner peripheral wall of the tip, and a keyhole communicating with the rear end of the guide hole 13A immediately or slightly apart It is composed of a main body 13B, and at least the left and right and upper and lower inner diameters (widths) W1 and W2 of the edge portion a of the tip insertion opening of the key hole 13 are the left and right outer and upper outer diameters (widths) of the tip 2a of the blade 2 of the key body Y ) It is larger than K1 and K2. Further, the keyhole body 13B for receiving the blade 2 at a position where the key cord 3 and the damper 20 coincide with each other is provided at either the front end portion or the center portion corresponding to the back of the edge portion a of the front end insertion port. ing.
ここで、図８と図９を参照にして説明する。まず、図８は、鍵穴１３の先端部（挿入口の縁部分）ａと合鍵Ｙのブレード２の外径の寸法差を示す正面視からの概略説明図である。内筒１２には、その回転軸に沿って、誘導穴１３Ａと該誘導穴１３Ａの連通する鍵穴本体１３Ｂとから成る鍵穴１３が形成され、本実施形態では、例えば図９で示すようにブレード２が多少左右方向に回転角度が傾いても（断面で示した部分の上方の長壁面が多少傾斜することを意味する。）、ブレード２の先細り状或いは弾丸状先端部２ａの外周面は、鍵穴１３の先端挿入口の縁部分ａとの間に十分な寸法差（間隙）が設定されていることから、自由にブレード２の先端部２ａを誘導穴１３Ａの先端挿入口の縁部分ａに嵌め合せることができる。 Here, a description will be given with reference to FIGS. First, FIG. 8 is a schematic explanatory view from the front view showing a dimensional difference between the outer diameters of the distal end portion (edge portion of the insertion port) a of the keyhole 13 and the blade 2 of the key Y. A key hole 13 including a guide hole 13A and a key hole main body 13B communicating with the guide hole 13A is formed in the inner cylinder 12 along the rotation axis. In this embodiment, as shown in FIG. Even if the rotation angle is slightly inclined in the left-right direction (meaning that the long wall surface above the portion shown in the cross section is slightly inclined), the outer peripheral surface of the tapered or bullet-like tip 2a of the blade 2 is a keyhole. Since a sufficient dimensional difference (gap) is set between the edge portion a of the tip insertion opening 13 and the edge portion a of the blade 2, the tip portion 2 a of the blade 2 is freely fitted to the edge portion a of the tip insertion opening of the guide hole 13 A Can be combined.
また、実施形態では、前記鍵穴１３の外拡状誘導穴１３Ａは、鍵穴１３の前記先端挿入口の縁部分ａから先端部の受入口の縁部分ｂまで、その内周面１３ａの内径が鍵本体Ｙの断面形状に対応して徐々に小さくなっている。 Further, in the embodiment, the outer expanding guide hole 13A of the key hole 13 has an inner diameter of the inner peripheral surface 13a from the edge portion a of the tip insertion opening of the key hole 13 to the edge portion b of the receiving port of the tip portion. The size gradually decreases corresponding to the cross-sectional shape of the main body Y.
実施形態の鍵穴１３の左右上下の側面形状は、鍵本体Ｙの断面形状に対応して非正多角形状に形成され、先端部寄りの部位に向かって次第に均等割合で狭くなっている。
そして、先端部寄りの部位の受入口の縁部分ｂに至ると、今度は縁部分ｂから奥部ｃに至るまで、前記左右及び上下の側面でもって、少なくともブレード２の先端部（断面で示した部分）側を支持することができる同一幅になっている。また実施形態では、鍵本体Ｙを鍵穴１３の奥まで完全に差し込むと、ブレード２は、少なくとも鍵穴１３の先端部寄りの部位ｂから後端部（奥部）ｃまでの左右及び上下の側面によって揺れないように支持される。
The left and right and upper and lower side surfaces of the keyhole 13 of the embodiment are formed in a non-regular polygon shape corresponding to the cross-sectional shape of the key body Y, and gradually narrow at an equal rate toward the portion closer to the tip.
Then, when reaching the edge portion b of the receiving port near the tip portion, at least the tip portion (shown in cross section) of the blade 2 from the edge portion b to the back portion c with the left and right and upper and lower side surfaces. The same width can be supported. Further, in the embodiment, when the key body Y is completely inserted to the back of the keyhole 13, the blade 2 is at least left and right and up and down from the portion b near the front end of the keyhole 13 to the rear end (back) c. It is supported not to shake.
次に図９及び図１０は、鍵穴１３の、先端（挿入口）の縁部分ａと先端部寄りの部位或いは実施形態によっては中央部寄りの部位の受入口の縁部分ｂと後端部（奥部）ｃの左右上下の各内径（幅）Ｗ１、Ｗ２と鍵本体Ｙのブレード２の左右上下の幅（大きさ）Ｋ１、Ｋ２の寸法差を示したものである。実施形態では、鍵穴１３の挿入口ａの形状は略真円円形（Ｗ１とＷ２は同一）であるが、鍵本体Ｙのブレード２の外周形状は、垂直断面の横幅Ｋ１と縦幅Ｋ２が同一の非正八角形である（図９参照）。 Next, FIG. 9 and FIG. 10 show the edge part b of the keyhole 13 at the front end (insertion port) and the part near the front end part or the part near the center part in some embodiments and the rear end part ( This shows the dimensional difference between the inner diameters (widths) W1 and W2 of the left and right and upper and lower sides of the back part c and the left and right and upper and lower widths (sizes) K1 and K2 of the blade 2 of the key body Y. In the embodiment, the shape of the insertion port a of the key hole 13 is substantially circular (W1 and W2 are the same), but the outer peripheral shape of the blade 2 of the key body Y is the same in the horizontal width K1 and the vertical width K2 in the vertical section. This is a non-regular octagon (see FIG. 9).
図１０から明らかなように、錠本体Ｘの内筒１２の鍵穴１３の先端挿入口の縁部分ａの左右・上下の内径（幅）Ｗ１、Ｗ２は、鍵本体Ｙのブレード２の面取りされた先端部２ａが余裕をもって遊嵌合する大きさであり、一方、前記鍵穴１３の少なくとも鍵穴本体１３Ｂの受入口の縁部分ｂの内径（幅）は、前記先端挿入口の縁部分ａの内径（幅）Ｗ１、Ｗ２よりも小さいので、鍵穴１３に対する挿入角度が多少大雑把であっても、つまり、合鍵Ｙの摘み部分１をもってブレード２の差し込み角度がいい加減であっても、ブレード２の先端部２ａを先端（挿入口）の縁部分ａ内に余裕をもって嵌め合せることができる。 As is apparent from FIG. 10, the left and right and upper and lower inner diameters (widths) W1 and W2 of the edge portion a of the tip insertion port of the key hole 13 of the inner cylinder 12 of the lock body X are chamfered on the blade 2 of the key body Y. The tip end 2a is of a size that can be loosely fitted with a margin. On the other hand, the inner diameter (width) of at least the edge portion b of the keyhole body 13B of the keyhole 13 is the inner diameter (width) of the edge portion a of the tip insertion port ( Width) Since it is smaller than W1 and W2, even if the insertion angle with respect to the keyhole 13 is somewhat rough, that is, even if the insertion angle of the blade 2 with the knob portion 1 of the key Y is moderate, the tip 2a of the blade 2 Can be fitted into the edge portion a of the tip (insertion opening) with a margin.
そこで、ブレード２の先端部２ａを鍵穴１３に差込む場合には、摘み部分を持ってブレード２の先端部２ａを鍵穴１３の先端挿入口に合わせるようにする。そして、ブレード２の先端部２ａを鍵穴１３の先端挿入口に嵌め合せたならば、鍵穴１３の先端部の案内面１３ａは、鍵穴本体１３Ｂの受入口の縁部分ｂに向かって徐々に絞りこまれているので、今仮に摘み部分１をもって押し込むと、ブレード２の先端部２ａは案内面１３ａに摺接状態で制御（補正）されるので、傾倒状態にあるブレード２は水平状態となり、スムースに鍵穴本体１３Ｂの受入口の縁部分ｂに至る。そこで、さらに摘み部分１を押し込むと、ブレード２に形成されたキーコード３と内筒１２の回転軸と直交する軸直角断面上に位置するダンブラー２０とが一致する。 Therefore, when the tip 2 a of the blade 2 is inserted into the keyhole 13, the tip 2 a of the blade 2 is aligned with the tip insertion opening of the keyhole 13 by holding a knob. When the tip 2a of the blade 2 is fitted into the tip insertion opening of the keyhole 13, the guide surface 13a at the tip of the keyhole 13 is gradually narrowed toward the edge b of the receiving hole of the keyhole body 13B. Since the tip 2a of the blade 2 is controlled (corrected) in sliding contact with the guide surface 13a if it is pushed in with the knob portion 1 at this time, the blade 2 in the tilted state is in a horizontal state and smoothly It reaches the edge portion b of the receiving port of the keyhole body 13B. Therefore, when the knob portion 1 is further pushed in, the key cord 3 formed on the blade 2 and the dumbler 20 located on the cross section perpendicular to the axis perpendicular to the rotation axis of the inner cylinder 12 coincide.
この時、ブレード２乃至摘み部分１の中心が内筒１２の回転軸Ｏと一致すると共に、本発明の結合手段５が圧接状態で係合し、内筒１２と鍵本体Ｙが共働可能となる。摘み部分１を回すと内筒１２が回り、内筒１２が回ると係合ピン（可動障害子）１７と共に多角形のブレード２も一緒に回転する。 At this time, the center of the blade 2 to the knob portion 1 coincides with the rotation axis O of the inner cylinder 12, and the coupling means 5 of the present invention is engaged in the press-contact state so that the inner cylinder 12 and the key body Y can work together. Become. When the knob portion 1 is rotated, the inner cylinder 12 is rotated, and when the inner cylinder 12 is rotated, the polygonal blade 2 is rotated together with the engagement pin (movable obstacle) 17.
すなわち、図３で示すように、第１係合部分７に対して第２係合部分９が係合するので、鍵本体Ｙの操作力が結合手段５を介して内筒１２に伝達することが可能となり、実施形態では、内筒１２の鍵穴１３とブレード２は互いに対応する４回転対称の係合関係にある多角形なので、摘み部分１でもって内筒１２を回すと、例えば図４の（ａ）の挿入時の状態から図４の（ｂ）の解錠位置へと時計方向へ９０度回すことができる。
なお、実施形態の鍵本体Ｙのブレード２は摘み部分１に対して回転可能に設けられているものの、鍵穴１３に挿入すると内筒１２と一緒に回転する。
That is, as shown in FIG. 3, since the second engagement portion 9 is engaged with the first engagement portion 7, the operating force of the key body Y is transmitted to the inner cylinder 12 via the coupling means 5. In the embodiment, the keyhole 13 and the blade 2 of the inner cylinder 12 are polygons having a four-rotation symmetrical engagement relationship corresponding to each other. Therefore, when the inner cylinder 12 is rotated with the knob portion 1, for example, FIG. It can be rotated 90 degrees clockwise from the state at the time of insertion of (a) to the unlocked position of (b) of FIG.
Although the blade 2 of the key body Y of the embodiment is provided so as to be rotatable with respect to the knob portion 1, it rotates together with the inner cylinder 12 when inserted into the key hole 13.
ところで、周知事項であるが、念のために、例えば図３を参照にして、付勢バネ１９、ダンブラー２０等の構成を説明する。ダンブラー２０は、係合ピン１７とドライバー１８とから成る。前記係合ピン１７は、貫通孔１６内で摺動可能な係合先端部分を有する軸部１７ａと、該軸部１７ａの外方に連設し、かつドライバー１８に接触可能な係合鍔１７ｂとからなる。係合ピン１７は、付勢バネ１９の弾発力によって、通常はドライバー１８と共に内方（鍵穴方向）へ付勢されるが、ピン孔１５と貫通孔１６との段差部に係合鍔１７ｂが当接することにより、内方への移動が規制されている。したがって、ダンブラー２０は、内側の係合ピン１７と、外側のドライバー１８とで構成され、付勢バネ１９のバネ力により、前記係合ピン１７の半円弧状係合先端部分が常に所定量鍵穴１３に突出している。 By the way, although it is a well-known matter, just in case, with reference to FIG. 3, the structure of the urging | biasing spring 19, the damper 20 etc. is demonstrated. The dumbler 20 includes an engagement pin 17 and a driver 18. The engagement pin 17 includes a shaft portion 17a having an engagement tip portion slidable in the through-hole 16, and an engagement rod 17b that is connected to the outside of the shaft portion 17a and can contact the driver 18. It consists of. The engagement pin 17 is normally urged inward (in the direction of the keyhole) together with the driver 18 by the resilient force of the urging spring 19, but the engagement rod 17 b is formed at the step portion between the pin hole 15 and the through hole 16. The inward movement is restricted by the contact. Accordingly, the damper 20 is composed of the inner engaging pin 17 and the outer driver 18, and the semicircular arc engaging tip portion of the engaging pin 17 is always a predetermined amount of keyhole by the spring force of the biasing spring 19. 13 protrudes.
実施形態では、ダンブラー２０（ピン孔１４、１５）は、上方と下方にそれぞれ軸方向に一直線に複数並んで列を成しているが、上下の各ダンブラー２０は、回転対称を考えて、例えば錠本体（内筒１２と外筒１１）Ｘを半径方向に裁断した軸直角断面上にそれぞれ位置している。そして、上下の各ダンブラー２０の円弧状係合先端部分は、鍵本体Ｙを鍵穴１３に挿入した際には、窪み３の略中心を通る。つまり、内筒１２の回転軸と直交するダンブラー２０用のピン孔１４、１５の半径方向の軸線と合鍵としての鍵本体Ｙの窪み３の中心を通る軸線は完全に一致する。 In the embodiment, the dumblers 20 (pin holes 14 and 15) are arranged in a plurality of lines in a straight line in the axial direction on the upper and lower sides, but each of the upper and lower dumblers 20 considers rotational symmetry, for example, The lock main bodies (inner cylinder 12 and outer cylinder 11) X are respectively positioned on the cross-section perpendicular to the axis obtained by cutting in the radial direction. The arcuate engagement tip portions of the upper and lower dampers 20 pass through the approximate center of the recess 3 when the key body Y is inserted into the key hole 13. That is, the axial line passing through the center of the recess 3 of the key body Y as a key is completely coincident with the radial axis of the pin holes 14 and 15 for the dumbler 20 orthogonal to the rotation axis of the inner cylinder 12.
実施形態の鍵穴１３の内周面の形状は、例えば長い幅面と短い幅面が交互に連続する非正多角形であり、この非正多角形の鍵穴１３の内周面に対応してブレード２の軸直角断面の外周形状が非正多角形で、かつ少なくとも３回転対称に形成され、さらに、前記軸直角断面上における同一長さの長壁面又は短壁面のいずれかには、周方向に所定の回転角を有して、少なくとも合計３つ以上の同一条件の窪み３（３ａ、３ｂ）がそれぞれ形成されており、鍵本体Ｙの摘み部分１を任意に把持して該鍵本体Ｙの回転方向における任意の位置の、少なくとも３つ以上の差し込み角度パターンで前記ブレード２を前記鍵穴１３の先端挿入口の円形状縁部分ａに「自由」に差込むことができる。 The shape of the inner peripheral surface of the key hole 13 of the embodiment is, for example, a non-regular polygon in which a long width surface and a short width surface are alternately continued, and the blade 2 corresponds to the inner peripheral surface of the non-regular polygon key hole 13. The outer peripheral shape of the cross section perpendicular to the axis is a non-regular polygon, and is formed to be at least three rotationally symmetric. Further, any one of the long wall surface and the short wall surface having the same length on the cross section perpendicular to the axis has a predetermined circumferential direction. A total of at least three depressions 3 (3a, 3b) having the same rotation angle and having the same rotation angle are formed, and the direction of rotation of the key body Y can be determined by arbitrarily gripping the knob portion 1 of the key body Y. The blade 2 can be “freely” inserted into the circular edge portion a of the distal end insertion opening of the key hole 13 in at least three insertion angle patterns at arbitrary positions.
そして、ブレード２の先端部２ａを円形状縁部分ａに差し込むと、内側に若干絞り込まれた、少なくとも左右・上下の案内面１３ａに前記先端部２ａが案内され、摘み部分１をさらに押し込むと、ブレード２の先端部２ａは案内面１３ａに制御（補正）されながらスムースに鍵穴本体１３Ｂの受入口の縁部分ｂに至る。 Then, when the tip 2a of the blade 2 is inserted into the circular edge portion a, the tip 2a is guided to at least the left and right and upper and lower guide surfaces 13a slightly narrowed inward, and when the knob portion 1 is further pushed, The tip 2a of the blade 2 smoothly reaches the edge b of the receiving port of the keyhole body 13B while being controlled (corrected) by the guide surface 13a.
摘み部分１を所要量押し込むと、ブレード２の窪み３は、必ず前記ダンブラー２０の複数の係合ピン１７の先端部に対して一致し、以て、摘み部分２又は鍵本体Ｙと共に内筒１２を解錠方向へ回動させることができる。なお、非正多角形でも角数が増えると、３回転対称から４回転対称、６回転対称などの如く、回転対称の数が増え、可能な限り真円に近づく。 When the required amount of the knob portion 1 is pushed in, the recess 3 of the blade 2 is always aligned with the tip ends of the plurality of engaging pins 17 of the damper 20, and thus the inner cylinder 12 together with the knob portion 2 or the key body Y. Can be rotated in the unlocking direction. Note that as the number of angles increases even in a non-regular polygon, the number of rotational symmetry increases, such as 3 rotational symmetry, 4 rotational symmetry, 6 rotational symmetry, and the like is as close to a perfect circle as possible.
以下、この実施例の欄では、本発明の第２実施形態、第３実施形態等を説明する。なお、説明の便宜上、第１実施形態と同一の部分には、同一或いは同様の符号を付して重複する説明を割愛する。 Hereinafter, in the column of this example, the second embodiment, the third embodiment, and the like of the present invention will be described. For convenience of explanation, the same parts as those in the first embodiment are denoted by the same or similar reference numerals, and redundant explanations are omitted.
まず図１５至図２３は、本発明の第２実施形態を示す各説明図である。この第２実施形態に於いて、第１実施形態と主に異なる事項は、（ａ）鍵本体Ｙ１のブレード２Ａの垂直断面の形状或いは外周形状が真円或いは略真円である点、（ｂ）ブレード２Ａに形成されたキーコード３Ａがブレードの長手方向に所定間隔を有して形成された複数の環状溝である点、（ｃ）錠本体Ｘ１の内筒１２の鍵穴本体１３Ｂの内周面がブレード２Ａの外周形状に対応して真円或いは略真円状に形成されている点、（ｄ）したがって、先端部寄りの部位の受入口の縁部分ｂも真円或いは略真円状である点、（ｅ）その他図１９で示すようにブレード２Ａの後端部が有底筒状の摘み部分に固定的に挿嵌されている点である。 First, FIG. 15 to FIG. 23 are explanatory diagrams showing a second embodiment of the present invention. In the second embodiment, the main difference from the first embodiment is that (a) the shape or outer peripheral shape of the vertical section of the blade 2A of the key body Y1 is a perfect circle or a substantially perfect circle. ) The key code 3A formed on the blade 2A is a plurality of annular grooves formed at predetermined intervals in the longitudinal direction of the blade, and (c) the inner periphery of the keyhole body 13B of the inner cylinder 12 of the lock body X1. (D) Therefore, the edge portion b of the receiving port near the tip is also a perfect circle or a substantially perfect circle, in that the surface is formed in a perfect circle or a substantially perfect circle corresponding to the outer peripheral shape of the blade 2A. (E) In addition, as shown in FIG. 19, the rear end portion of the blade 2A is fixedly inserted into the bottomed cylindrical knob portion.
なお、第２実施形態の鍵本体Ｙ１は、ブレード２Ａと摘み部分１は互いに回転可能に設けられているが、両方は回転可能でなくても良い。また、鍵本体Ｙ１の環状溝３Ａは、大径部分と小径部分が基端部から先端へと連続模様を形成するように繰替えされているが、環状溝３Ａの幅、形状、深さ等は任意に設計変更することができる事項である。第２実施形態の主要部及び要部は、第１実施形態と同様なので、ここでは極力同様の図面を描いて具体的な説明は割愛する。 In the key body Y1 of the second embodiment, the blade 2A and the knob portion 1 are provided so as to be rotatable relative to each other, but both may not be rotatable. Further, the annular groove 3A of the key body Y1 is repeated so that the large-diameter portion and the small-diameter portion form a continuous pattern from the proximal end portion to the distal end, but the width, shape, depth, etc. of the annular groove 3A Is an item that can be arbitrarily changed in design. Since the main part and the main part of the second embodiment are the same as those of the first embodiment, a detailed description is omitted here by drawing the same drawings as much as possible.
次に、図２４乃至図２６は、第３実施形態、第４実施形態及び第５実施形態を示す。これらの実施形態は、結合手段５Ａ、結合手段５Ｂ、結合手段５Ｃがそれぞれ異なる。
図２４の結合手段５Ａはセレーション（多数の溝）である。すなわち、内筒１２の前部６には、その周方向にセレーションとしての第１係合部分７Ａが形成され、一方、摘み部分１の先端部８には、その周方向にセレーションとしての第２係合部分９Ａが形成されている。

An engaging portion 9A is formed.
図２５の結合手段５Ｂは磁性体（第１磁性体７Ｂと第２磁性体９Ｂ）である。すなわち、内筒１２の前部６には、その周方向に所定間隔を有して第１磁性体７Ｂが固設され、一方、摘み部分１の先端部８には、その周方向に第１磁性体の極性に対応して吸着する複数個の第２磁性体９Ｂが固設されている。なお、この第３実施形態では両方に磁性体を配設しているが、結合手段５Ｂは、内筒１２の前部６又は摘み部分１の先端部８のいずれか一方が金属であり、他方が前記金属に吸着する磁性体であっても良い。 The coupling means 5B in FIG. 25 is a magnetic body (first magnetic body 7B and second magnetic body 9B).

A buffer spring 24 for coalescence is provided.
（２）錠本体Ｘ２の鍵穴１３
錠本体Ｘ２の鍵穴１３は、水平方向又は垂直方向のいずれであっても良い。また鍵穴１３の形状は、例えばブレード部分と称される差込み部分の両側縁部分に刻み状の鍵溝を有するもの、又はブランキーと称される平坦面に幾何学的溝、逆円錐台状窪み等を有するものがそれぞれ挿入可能なものであれば良い。図２８及び図２９で示すように、本実施形態のブレード２Ｂは、外周面に複数の凹所（窪み）を有する棒状形態をしているので、錠本体Ｘ２の鍵穴１３は、例えば単純な水平方向や垂直方向の穴ではなく、鍵穴１３は円形、楕円形、十字形状等に形成され、かつ鍵穴１３の開口縁部分に傾斜状案内面（キー誘導面）１３ａを有している。
(2) Key hole 13 of lock body X2
The keyhole 13 of the lock body X2 may be either in the horizontal direction or in the vertical direction. Further, the shape of the key hole 13 is, for example, one having notched key grooves on both side edge portions of the insertion portion referred to as a blade portion, or a geometric groove, inverted frustoconical recess or the like on a flat surface referred to as a blank key. It is sufficient that each of those having a can be inserted. As shown in FIGS. 28 and 29, since the blade 2B of the present embodiment has a rod-like shape having a plurality of recesses (dents) on the outer peripheral surface, the key hole 13 of the lock body X2 is, for example, a simple horizontal The keyhole 13 is formed in a circular shape, an oval shape, a cross shape, or the like instead of a hole in the direction or the vertical direction, and has an inclined guide surface (key guide surface) 13 a at the opening edge portion of the keyhole 13.
（３）ブレード２Ｂ
図２８はブレード２Ｂの正面図を基準にした説明図である。また図２９はブレード２Ｂの左側面図である。ブレード２Ｂの具体的構成態様は、本発明の特定要件ではないので、詳細な説明は割愛するが、図２８及び図２９で示すように、ブレード２Ｂは、弾丸状先端部２ａ及び複数種類のキーコード３Ｂを有するブレード本体３２と、このブレード本体３２に連続する大径後端部３３側（キー軸後端部２ｂ）に区別され、ここでは前記大径後端部３３からフランジ状後端部２５までを「キー軸後端部２ｂ」とする。
(3) Blade 2B
FIG. 28 is an explanatory diagram based on the front view of the blade 2B. FIG. 29 is a left side view of the blade 2B. Since the specific configuration of the blade 2B is not a specific requirement of the present invention, detailed description will be omitted. However, as shown in FIGS. 28 and 29, the blade 2B includes a bullet-shaped tip 2a and a plurality of types of keys. A blade main body 32 having a cord 3B and a large-diameter rear end portion 33 side (key shaft rear end portion 2b) continuous with the blade main body 32 are distinguished. Here, the large-diameter rear end portion 33 is connected to the flange-shaped rear end portion. Up to 25 is defined as “key shaft rear end 2b”.
前述したように、前記ブレード本体３２の先端部分２ａは弾頭状或いは指先状に形成されている。またブレード本体３２は、軸方向に沿った縦断面の長さが位置によって変化する外形線（ブレード２Ｂの軸方向に凸所と凹所が繰返す意味）を有する中実棒状体である。さらに、弾丸状先端部２ａは、図２８で示すように、キーコード３Ｂを有するブレード本体３２よりも半径がさらに小さい挿入部分である。加えて前記キーコード３Ｂは、図２９で示すように、上下の対角線方向の外面部位の深さが略同一の溝である。 As described above, the tip portion 2a of the blade body 32 is formed in a warhead shape or a fingertip shape. The blade main body 32 is a solid rod-like body having an outline (meaning that a convex portion and a concave portion repeat in the axial direction of the blade 2B) in which the length of the longitudinal section along the axial direction changes depending on the position. Furthermore, as shown in FIG. 28, the bullet-shaped tip portion 2a is an insertion portion having a smaller radius than the blade body 32 having the key cord 3B. In addition, as shown in FIG. 29, the key code 3B is a groove having substantially the same depth of the outer surface portion in the upper and lower diagonal directions.
ところで、図２８で示す小さな楕円形状に見える箇所が前記溝内の外面に形成したキーコードとしての窪み２６ａであり、実施形態のブレード本体３２は、半径方向の窪み２６ａ以外に、前述した軸方向の波状外形線もキーコード３Ｂとして用いることができる。 By the way, a portion that looks like a small ellipse shown in FIG. 28 is a depression 26a as a key code formed on the outer surface in the groove, and the blade body 32 of the embodiment has the axial direction described above in addition to the depression 26a in the radial direction. The wavy outline can also be used as the key code 3B.
キー軸後端部２ｂは、左右上下に突起部分２７、２８を有し、後端部の＋形状の突起部分２８は、図３３で示すように内係合体２９の内周面に形成した＋形状の被係合部分に係合する。したがって、内係合体２９は軸方向に移動可能であるものの、キー軸後端部２ｂの＋形状突起部分（係合部分）と＋形状の被係合部分は一体的に係合することから、ブレード２Ｂと共に共働回転可能である。 The rear end 2b of the key shaft has protrusions 27 and 28 on the left and right and up and down, and the + -shaped protrusion 28 at the rear end is formed on the inner peripheral surface of the inner engagement body 29 as shown in FIG. Engages with the engaged portion of the shape. Therefore, although the inner engagement body 29 is movable in the axial direction, the + -shaped protrusion portion (engagement portion) and the + -shaped engaged portion of the key shaft rear end 2b are integrally engaged, Co-rotation with the blade 2B is possible.
（４）トリガー部材１０
例えば図３３及び図３４で示すように、トリガー部材１０は、内係合体２９と共にキー軸後端部２ｂに外嵌合しているが、実施形態では、内係合体２９よりも前方の前記キー軸後端部に軸方向に移動可能に設けられている。
(4) Trigger member 10
For example, as shown in FIGS. 33 and 34, the trigger member 10 is fitted to the key shaft rear end 2b together with the inner engagement body 29, but in the embodiment, the key forward of the inner engagement body 29 is the key. A shaft rear end portion is provided so as to be movable in the axial direction.
しかして、トリガー部材１０は、キー軸後端部２ｂに外嵌合する筒状部分３０と、この筒状部分３０の左右部位に基端部が固定された左右一対の水平係合腕３１と、これらの水平係合腕３１の基端部と交差するように前記筒状部分３０の後端部の左右部位に突設された左右一対の連結突片と、これらの連結突片に対向する左右一対の合わせ突片を介して筒状部分３０の後端面に一体的に連結され、しかも、その内周面にノコギリ状の内係合歯４０ａが形成された外係合体４０とから構成され、前記水平係合腕３１の突出外端部（トリガー先端部）１０ａは、トリガー部材１０が摘み部分１Ｂ内装の左右一対の復帰バネ２３のバネ力により付勢されていることから、常に摘み部分１Ｂ（下方の板状摘み片１ａ）の先端部８から所定量突出している。なお、前記筒状部分３０と外係合体４０は一体成形しても良い。 Thus, the trigger member 10 includes a cylindrical portion 30 that is fitted outside the key shaft rear end portion 2b, and a pair of left and right horizontal engaging arms 31 that have base ends fixed to the left and right portions of the cylindrical portion 30. A pair of left and right connecting protrusions projecting from the left and right portions of the rear end of the cylindrical portion 30 so as to intersect with the base ends of the horizontal engagement arms 31, and these connecting protrusions are opposed to each other. The outer engagement body 40 is integrally connected to the rear end surface of the cylindrical portion 30 via a pair of right and left alignment protrusions, and has a saw-like inner engagement tooth 40a formed on the inner peripheral surface thereof. The protruding outer end portion (trigger tip portion) 10a of the horizontal engagement arm 31 always has a knob portion because the trigger member 10 is biased by the spring force of the pair of left and right return springs 23 in the knob portion 1B. 1B (lower plate-shaped tab 1a) protrudes from the tip 8 by a predetermined amount. . The cylindrical portion 30 and the outer engagement body 40 may be integrally formed.
（５）作用
次に作用を説明する。図４０は内外の歯車体の位相が一致していた場合におけるトリガー部材１０の作動の説明図である。そして、図３７は位相が一致していた場合の概念図である。内外の歯車体２９、４０の位相が一致している、一致していないに関わらず、摘み部分１Ｂを持ってブレード２Ｂを錠本体Ｘ２の鍵穴１３に差込んで行く。この時、鍵穴１３の先端挿入口の縁部分には、ブレード２Ｂを内筒１２Ｂの回転軸と一致するように鍵穴１３の中心へと誘導する外拡状案内面１３ａが形成されているので、ブレード２Ｂの中心と鍵穴１３は、内筒１２Ｂの回転軸上に略一致する。そして、ブレード２Ｂを鍵穴１３に差込んで行くと、まずトリガー部材１０の水平係合腕３１の突出外端部１０ａの先端面が鍵穴１３の周囲（一部も含む）に当たる。その状態で摘み部分１Ｂを相手（錠本体Ｘ２）側にさらに押し込むと、内外の歯車体２９，４０の外係合歯２９ａと内係合歯４０ａの位相が一致しているので、トリガー部材１０は矢印で示す方向へ復帰バネ２３のバネ力に抗して所要量移動し、前記外係合歯２９ａと内係合歯４０ａが直ちに噛合状態となり、その結果、ブレード２Ｂ側の内係合体２９と摘み部分１Ｂ側或いは該摘み部分１Ｂと共働回転し得るように組み込まれたトリガー部材１０側の外係合体４０が連結状態となる。
(5) Operation Next, the operation will be described. FIG. 40 is an explanatory view of the operation of the trigger member 10 when the phases of the inner and outer gear bodies match. FIG. 37 is a conceptual diagram when the phases match. Regardless of whether or not the phases of the inner and outer gear bodies 29 and 40 are matched, the blade 2B is inserted into the key hole 13 of the lock body X2 with the knob portion 1B. At this time, since the outer edge of the guide hole 13a that guides the blade 2B to the center of the keyhole 13 so as to coincide with the rotation axis of the inner cylinder 12B is formed at the edge portion of the tip insertion opening of the keyhole 13, The center of the blade 2B and the keyhole 13 substantially coincide with the rotation axis of the inner cylinder 12B. When we crowded difference blade 2B to keyhole 13, first distal end surface of the projecting outer end portion 10 a of the horizontal engagement Goude 31 of the trigger member 10 hits the keyhole 13 around the (partially including also). In this state, when the knob portion 1B is further pushed into the counterpart (lock body X2) side, the phases of the outer engagement teeth 29a of the inner and outer gear bodies 29, 40 and the inner engagement teeth 40a coincide with each other. Moves in the direction shown by the arrow against the spring force of the return spring 23, and the outer engagement teeth 29a and the inner engagement teeth 40a immediately mesh with each other, and as a result, the inner engagement body 29 on the blade 2B side. The outer engagement body 40 on the trigger member 10 side which is incorporated so as to be able to rotate together with the knob portion 1B or the knob portion 1B is connected.
一方、図３８は内外の歯車体の位相が一致していない場合におけるトリガー部材１０の作動の説明図である。そして、図３９は位相が一致していない場合の概念図である。位相が一致していない場合は、当然のことながら、トリガー部材１０が復帰バネ２３のバネ力に抗して所定量（例えば３ｍｍ）移動する。その際、内係合体２９は外係合体４０の後端面で押されるので、緩衝バネ２４はバネ力に抗して収縮する。 On the other hand, FIG. 38 is an explanatory view of the operation of the trigger member 10 when the phases of the inner and outer gear bodies do not match. FIG. 39 is a conceptual diagram when the phases do not match. If the phases do not match, the trigger member 10 naturally moves by a predetermined amount (for example, 3 mm) against the spring force of the return spring 23. At this time, since the inner engagement body 29 is pushed by the rear end face of the outer engagement body 40, the buffer spring 24 contracts against the spring force.
そこで、摘み部分１Ｂを左右いずれかの方向へ回転させる。そうすると、実施形態では、内外の係合体２９，４０の外係合歯２９ａと内係合歯４０ａは、いわゆるスプライン、或いはセレーション状に形成されているので、両係合歯２９ａ、４０ａは容易に一致し、緩衝バネ２４で押し戻された内係合体２９は外係合体４０に嵌入する。つまり、両係合体２９，４０は可及的速やかに噛合する。その結果、噛合態様で摘み部分１Ｂとトリガー部材１０とブレード２Ｂがそれぞれ共働回転するように一体的に結合する。 Therefore, the knob portion 1B is rotated in either the left or right direction. Then, in the embodiment, since the outer engagement teeth 29a and the inner engagement teeth 40a of the inner and outer engagement bodies 29, 40 are formed in a so-called spline or serration, both the engagement teeth 29a, 40a can be easily formed. The inner engagement body 29 that matches and is pushed back by the buffer spring 24 fits into the outer engagement body 40. That is, the engaging bodies 29 and 40 mesh as quickly as possible. As a result, the knob portion 1B, the trigger member 10, and the blade 2B are integrally coupled so as to rotate together in a meshing manner.
ところで、図２７はブレード２Ｂの先端部を錠本体Ｘ２の鍵穴１３に差込んだ態様における主要部の説明図であるが、この図１は挿入時と引抜き時の両方を兼用する説明図である。つまり、ブレード２Ｂを鍵穴１３から引き抜く際、左右一対の復帰バネ２３で付勢されたトリガー部材１０は初期位置へと移動し、その結果、トリガー部材１０の外係合体４０は内係合体２９から離れる（噛合状態の解消）。 Incidentally, FIG. 27 is an explanatory view of the main part in a mode in which the tip end portion of the blade 2B is inserted into the key hole 13 of the lock body X2. FIG. 1 is an explanatory view for both the insertion time and the extraction time. . That is, when the blade 2B is pulled out from the key hole 13, the trigger member 10 biased by the pair of left and right return springs 23 moves to the initial position, and as a result, the outer engagement body 40 of the trigger member 10 moves from the inner engagement body 29. Leave (disengagement of meshing state).
図４２乃至図４５は本発明の第７実施形態を示す各説明図である。この第７実施形態は前記第６実施形態の第２結合手段を設計変更したものである。第６実施形態の第２結合手段は、摘み部分１Ｂに設けたトリガー部材１０の先端面が鍵穴１３の周囲（一部も含む）に当たりながら復帰バネ２３のバネ力に抗して後退し、第２結合手段としての前記トリガー部材１０に設けられた外係合体４０の内係合歯４０ａとブレード２Ｂのキー軸後端部２ｂに設けた内係合体２９の外係合歯２９ａが互いに噛合することを条件として摘み部分１Ｂとトリガー部材１０とブレード２Ｂが共働回転する。これに対して、第７実施形態の第２結合手段は、トリガー部材１０Ａに設けられた外係合体４０Ａの多角形状の内係合面４０ａとブレード２Ｂのキー軸後端部２ｂに設けた内係合体２９Ａの多角形状の外係合面２９ａが互いに係合することを条件として摘み部分１Ｂとトリガー部材１０Ａとブレード２Ｂが共働回転する。なお、図示しない復帰バネ２３、緩衝バネ２４等は、第６実施形態と同様に摘み部分１Ｂに組み込まれている。 42 to 45 are explanatory views showing a seventh embodiment of the present invention. In the seventh embodiment, the design of the second coupling means of the sixth embodiment is changed. The second coupling means of the sixth embodiment moves backward against the spring force of the return spring 23 while the front end surface of the trigger member 10 provided in the knob portion 1B hits the periphery (including part of) the keyhole 13, The inner engagement teeth 40a of the outer engagement body 40 provided on the trigger member 10 as two coupling means and the outer engagement teeth 29a of the inner engagement body 29 provided on the key shaft rear end 2b of the blade 2B mesh with each other. On this condition, the knob portion 1B, the trigger member 10, and the blade 2B rotate together. On the other hand, the second coupling means of the seventh embodiment includes an inner engagement surface 40a of the outer engagement body 40A provided on the trigger member 10A and an inner side provided on the key shaft rear end portion 2b of the blade 2B. The knob portion 1B, the trigger member 10A, and the blade 2B rotate together on condition that the polygonal outer engagement surfaces 29a of the engagement body 29A are engaged with each other. In addition, the return spring 23, the buffer spring 24, etc. which are not shown in figure are integrated in the knob | pick part 1B similarly to 6th Embodiment.
図４６乃至図５１は本発明の第８実施形態を示す各説明図である。まず、図４６及び図４７は、ピンシリンダー錠が錠本体Ｘ３と鍵本体Ｙ２から成ることを示す各説明図である。錠本体Ｘ３も第１実施形態の錠本体Ｘと同様に可動障害子２０が直線方向（内筒の半径方向）に移動するピンシリンダーである（図４８、図４９参照）。 46 to 51 are explanatory views showing an eighth embodiment of the present invention. 46 and 47 are explanatory views showing that the pin cylinder lock is composed of a lock body X3 and a key body Y2. Similarly to the lock body X of the first embodiment, the lock body X3 is also a pin cylinder in which the movable obstacle 20 moves in the linear direction (radial direction of the inner cylinder) (see FIGS. 48 and 49).
したがって、錠本体Ｘ３は、例えば図４７で示すように、外筒１１Ｃと、この外筒に回動可能に設けられ鍵穴１３を有する内筒１２Ｃと、外筒１１Ｃ及び内筒１２Ｃに渡って付勢バネ１９の弾発力を付与して挿通されたドライバーピン１８とタンブラーピン１７とを有し、かつ、外筒１１Ｃと内筒１２Ｃの境目に相当するシェアラインＬに前記タンブラーピン１７の鍔状外端部を位置させることができるにように該シェアラインＬに沿って配設された複数列のピン群を備える。前記タンブラーピン１７の係合内端部１７ｂは、図４７で示すように、鍵本体Ｙ２を錠本体Ｘ３に差し込む前は鍵穴１３に所定量出ている。なお、内筒の後端部に設けられた回転軸（テールピース）、ワッシャー、外筒の外周面に形成した切欠用カバーなどの細部的事項の説明は割愛する。 Therefore, as shown in FIG. 47, for example, the lock body X3 is attached to the outer cylinder 11C, the inner cylinder 12C rotatably provided on the outer cylinder and having the key hole 13, and the outer cylinder 11C and the inner cylinder 12C. It has a driver pin 18 and a tumbler pin 17 that are inserted by applying a spring force of the force spring 19, and the tub of the tumbler pin 17 is in a share line L corresponding to the boundary between the outer cylinder 11C and the inner cylinder 12C. A plurality of rows of pin groups arranged along the share line L so that the outer end portion can be positioned. As shown in FIG. 47, the engagement inner end portion 17b of the tumbler pin 17 protrudes from the key hole 13 by a predetermined amount before the key body Y2 is inserted into the lock body X3. In addition, description of detailed matters, such as the rotating shaft (tail piece) provided in the rear-end part of the inner cylinder, a washer, the cover for notches formed in the outer peripheral surface of an outer cylinder, is omitted.
しかして、錠本体Ｘ３のタンブラーは、例えば図４９で示すように、少なくとも第１列のピン群Ｌ１と、該第１列のピン群に対して１８０度対向位置に存在する第２列のピン群Ｌ２とから成る。また、例えば図５０で示すように、第１列のピン群Ｌ１又は第２列のピン群Ｌ２に対して、４５度位置に第３列のピン群が配設され、この第３列のピン群Ｌ３の各タンブラーピン（係合ピン）１７は、第１キーコード（Ｃ１）の凹所の深さに対応して係合する。また、第１列のピン群Ｌ１又は第２列のピン群Ｌ２に対して、４５度位置に外筒１１Ｃ及び内筒１２Ｃに渡って弾発手段４７の弾発力を付与して圧接面山形形状のクリックピン４８及びクリックピン受け４９が設けられている。 Thus, the tumbler of the lock body X3 includes, for example, as shown in FIG. 49, at least the first row of pin groups L1 and the second row of pins that are 180 degrees opposite to the first row of pin groups. It consists of group L2. For example, as shown in FIG. 50, a third row of pin groups is disposed at a 45 degree position with respect to the first row of pin groups L1 or the second row of pin groups L2, and this third row of pins. Each tumbler pin (engagement pin) 17 of the group L3 engages corresponding to the depth of the recess of the first key cord (C1). Further, the elastic force of the elastic means 47 is applied to the first row pin group L1 or the second row pin group L2 over the outer cylinder 11C and the inner cylinder 12C at a 45 degree position to form a pressure contact surface mountain shape. A click pin 48 and a click pin receiver 49 having a shape are provided.
次に、鍵本体Ｙ２は、第６実施形態の鍵本体Ｙ２と同一のものが使用されている。したがって、鍵本体Ｙ２のキーコードは、ブレードの半径方向に形成された大小の凹所状第１キーコード（Ｃ１）と、ブレード２Ｂの軸方向の外周面に形成された波状の高低差を有する第２キーコード（Ｃ２）とから成る。なお、鍵本体Ｙ２の具体的構成は、第６実施形態の鍵本体Ｙ２の説明を援用し、重複する説明を割愛する。 Next, the key body Y2 is the same as the key body Y2 of the sixth embodiment. Therefore, the key code of the key body Y2 has a corrugated height difference formed on the outer circumferential surface of the blade 2B in the axial direction of the large and small concave first key code (C1) formed in the radial direction of the blade. It consists of a second key code (C2). The specific configuration of the key body Y2 uses the description of the key body Y2 of the sixth embodiment, and omits the overlapping description.
