The shift drum 13 can be turned counterclockwise by 90 degrees while the operating shaft 11 is moved backward, and the latching piece 4 can be turned off from the fixed receiving portion S in the main body of the rocker L and unlocked accordingly.

また、符号列を忘れた場合等の非常時に際し、管理人等により非常鍵を使用して解錠することができるように構成しており、即ち、摘み７に設けた鍵孔８に非常鍵を挿入してシリンダ錠機構におけるタンブラによるシフトドラム１３の係合を解除した状態のもとに、シフトドラム１３に関係なく掛止片４を旋回して解錠することができるようにする。  Further, in the event of an emergency such as when the code string is forgotten, the administrator can unlock it using the emergency key, that is, the emergency key is provided in the key hole 8 provided in the knob 7. The latch piece 4 can be turned and unlocked regardless of the shift drum 13 under the state where the engagement of the shift drum 13 by the tumbler in the cylinder lock mechanism is released.

上記構成は、従来一般のこの種のダイヤル錠装置における構成と性質的に大差はない。上記構成に対する本発明の特殊構成としては、クラッチ１５の一側端寄りの延長筒部の外周面にキー溝１５ｂに対応した特定位置に断面がほぼ長方形の符号探索用の凹部２２を設けるのであって、即ちこの実施形態においては、作動軸１１におけるキー片１４を前方正面に設けると共に、このキー片１４とクラッチ１５のキー溝１５ｂとが合致した状態におけるクラッチ１５の右側面位置に設ける。  The above configuration is not significantly different from the configuration of this type of conventional dial lock device. As a special configuration of the present invention with respect to the above configuration, a code search recess 22 having a substantially rectangular cross section is provided at a specific position corresponding to the key groove 15b on the outer peripheral surface of the extended cylindrical portion near one end of the clutch 15. That is, in this embodiment, the key piece 14 on the operating shaft 11 is provided on the front front side, and is provided on the right side surface position of the clutch 15 in a state where the key piece 14 and the key groove 15b of the clutch 15 are aligned.

符号探索用の各凹部２２に対して、進退係合する棒状の探索ピン２３を各別に対設するのであるが、各ダイヤルリング１０列の右側部においてクラッチ１５の軸線と直交する方向即ち図２および図３において左右方向に進退可能な探索枠２４をケース５内に配設すると共に、探索枠２４には扁平な指片２５をクラッチ１５の軸線に対して直交状態に突設して探索枠２４の進退に伴い各指片２５を対応クラッチ１５の外周に接離するようにし、かつ指片２５には図２のように受け孔２６を設けてこの受け孔２６に前記探索ピン２３をコイルばね２７により一定程度進出し易い傾向に収容し、これにより探索枠２４の進出に伴い探索ピン２３の先端をクラッチ１５の外周に弾接するように構成する。  A bar-like search pin 23 that engages and retreats is provided separately for each recess 22 for code search, but in the right side of each dial ring 10 row, the direction orthogonal to the axis of the clutch 15, that is, FIG. In FIG. 3, a search frame 24 that can be moved back and forth in the left-right direction is disposed in the case 5, and a flat finger piece 25 is provided on the search frame 24 so as to protrude perpendicular to the axis of the clutch 15. Each finger piece 25 is brought into contact with and separated from the outer periphery of the corresponding clutch 15 with the advance and retreat of 24, and the finger piece 25 is provided with a receiving hole 26 as shown in FIG. 2, and the search pin 23 is coiled in the receiving hole 26. The spring 27 is accommodated in a tendency to advance to a certain extent, whereby the tip of the search pin 23 is configured to elastically contact the outer periphery of the clutch 15 as the search frame 24 advances.

前記探索枠２４には受動ピン２８を突設すると共に、この受動ピン２８に係合する傾斜長孔２９がある板状の中継体３０をクラッチ１５の軸線に対して平行に進退可能に設け、かつ中継体３０の基端には受動部３１とばね受部３２とを設けて、ばね受部３２とケース５に形成したばね収容部３３との間にコイルばね３４を介装し、中継体３０をコイルばね３４により常時後退傾向に付勢して探索枠２４を図２および図３のように右方に後退した状態に保つようにする。  The search frame 24 is provided with a passive pin 28 and a plate-like relay body 30 having an inclined elongated hole 29 engaged with the passive pin 28 is provided so as to be able to advance and retreat in parallel with the axis of the clutch 15. A passive portion 31 and a spring receiving portion 32 are provided at the proximal end of the relay body 30, and a coil spring 34 is interposed between the spring receiving portion 32 and the spring accommodating portion 33 formed in the case 5. 30 is constantly biased by the coil spring 34 so as to keep the search frame 24 retracted to the right as shown in FIGS.

前記摘み７には駆動腕３５を突設してこの駆動腕３５の旋回範域に前記中継体３０における受動部３１を対応させ、必要に応じて摘み７を旋回させることにより、駆動腕３５を中継体３０における受動部３１に押圧させて中継体３０をコイルばね３４に抗して進出させ、中継体３０の進出により傾斜長孔２９と受動ピン２８との協働のもとに探索枠２４をクラッチ１５寄りに進出させ、これにより探索ピン２３をクラッチ１５の周側面に弾接させる。  A drive arm 35 protrudes from the knob 7 so that the passive portion 31 of the relay body 30 corresponds to the turning range of the drive arm 35, and the knob 7 is turned as necessary to turn the drive arm 35. The relay body 30 is pressed against the coil spring 34 by pressing the passive portion 31 in the relay body 30, and the search frame 24 is cooperated with the inclined long hole 29 and the passive pin 28 by the advancement of the relay body 30. Is advanced toward the clutch 15, whereby the search pin 23 is brought into elastic contact with the peripheral side surface of the clutch 15.

解錠符号の探索に当っては、施錠状態即ち図３および図６（ａ）のように、作動軸１１は下方へ進出してその先端がシフトドラム１３の谷部２１ｂに係合したまま、各クラッチ１５は上方へ後退してダイヤルリング１０と係合しており、この状態のもとに、図７のように、鍵孔８に非常鍵を挿入して摘み７を反時計方向に９０度プラス４５度回転させることにより、シフトドラム１３を回転させることなく、掛止片４を固定受部Ｓから離脱させ、かつ摘み７に設けた駆動腕３５により中継体３０を上方へ押動進出させ、中継体３０の進出に伴い探索枠２４をクラッチ１５寄りに押動進出させ、これにより全数の探索ピン２３の先端を対応する各クラッチ１５の周側面に弾接させた探索待機状態とする。  In the search for the unlocking code, as shown in FIG. 3 and FIG. 6A, the operating shaft 11 advances downward and its tip is engaged with the valley portion 21b of the shift drum 13, as shown in FIG. Each clutch 15 is retracted upward and engaged with the dial ring 10. Under this state, as shown in FIG. 7, an emergency key is inserted into the key hole 8 and the knob 7 is turned counterclockwise by 90. Rotation angle 45 degrees, without causing the shift drum 13 to rotate, the retaining piece 4 is detached from the fixed receiving portion S, and the relay body 30 is pushed upward by the driving arm 35 provided on the knob 7. As the relay body 30 advances, the search frame 24 is pushed and advanced closer to the clutch 15, thereby setting the search standby state in which the tips of all the search pins 23 are elastically contacted with the peripheral side surfaces of the corresponding clutches 15. .

探索待機状態においては、ダイヤルリング１０は通常図６（ａ）のようにクラッチ１５と係合したまま回転が自由であるから、ダイヤルリング１０を回転して符号を順次にずらすと、クラッチ１５の凹部２２も間欠回動して探索ピン２３と出会った位置で探索ピン２３は凹部２２に落ち込んで回動が阻止され、（図７における最上位のクラッチ１５を参照）その位置におけるダイヤルリング１０の正面の符号が解錠符号であり、全数のダイヤルリング１０について同様の操作を行うことにより、解錠符号列が判明する。  In the search standby state, the dial ring 10 is normally free to rotate while being engaged with the clutch 15 as shown in FIG. 6A. Therefore, when the dial ring 10 is rotated and the signs are sequentially shifted, The recess 22 is also intermittently rotated so that the search pin 23 falls into the recess 22 at a position where it meets the search pin 23 (see the uppermost clutch 15 in FIG. 7). A front code | symbol is an unlocking code | symbol, and the unlocking code | symbol string | code becomes clear by performing the same operation about all the dial rings 10. FIG.

設定していた解錠符号が確認できたならば、非常鍵を挿入したまま摘み７を時計方向に１３５度回転すると、駆動腕３５による中継体３０への押動が解除されてコイルばね３４により中継体３０は後退復元し、これに伴い探索枠２４も後退復元して各探索ピン２３は凹部２２から脱出し、ダイヤルリング１０に解錠符号が示された施錠状態となり、ダイヤルリング１０の回転が可能となる。その後非常鍵を抜き取りダイヤルリング１０を適宜回転して解錠符号を乱すことにより、他人に解錠符号を読み取られないようにする。  If the unlocking code that has been set is confirmed, when the knob 7 is rotated 135 degrees clockwise with the emergency key inserted, the pushing of the driving arm 35 to the relay body 30 is released and the coil spring 34 The relay body 30 is retracted and restored, so that the search frame 24 is also retracted and restored, and each search pin 23 comes out of the recess 22, and the dial ring 10 is in a locked state in which an unlocking code is shown, and the dial ring 10 rotates. Is possible. Thereafter, the emergency key is taken out and the dial ring 10 is appropriately rotated to disturb the unlocking code so that others cannot read the unlocking code.

前記クラッチ１５に隣接する軸受部材１７の一側の端面には少なくとも左右両側に受動鍔部３６を設けると共に、受動鍔部３６の後端縁には斜め下向きの傾斜受面３６ａを形成し、これに対し、軸受部材１７付近から背方には軸受部材１７の軸線とほぼ直交する前後方向の案内用すべり軸受３７を主ケース５ａに設けると共に、このすべり軸受３７には、背部に押しボタン３８があるほか、先端寄り部が二股に形成された駆動端３９があり、駆動端３９の先端に受動鍔部押圧用の傾斜押圧面３９ａが斜め上向きに形成された切換用操作体４０を前後方向に進退可能に設け、図４のように、切換用操作体４０を後方に引き出した後退状態においては、駆動端３９は受動鍔部３６から離反するから、軸受部材１７はシフトドラム１３のカム面の対応位置に規制されて進退し、必要に応じてダイヤルリング１０を自由に回転させることができ、従って解錠符号の変換が可能な自由変換型として機能する。  At one end face of the bearing member 17 adjacent to the clutch 15 is provided with passive saddle portions 36 at least on both the left and right sides, and at the rear end edge of the passive saddle portion 36 is formed an obliquely downward inclined receiving surface 36a. On the other hand, from the vicinity of the bearing member 17 to the back, a slide bearing 37 for guiding in the front-rear direction substantially orthogonal to the axis of the bearing member 17 is provided in the main case 5a, and a push button 38 is provided on the back of the slide bearing 37. In addition, there is a drive end 39 having a tip end portion formed in a bifurcated manner, and a switching operation body 40 in which an inclined pressing surface 39a for pressing a passive hook portion is formed obliquely upward at the tip of the drive end 39 in the front-rear direction. As shown in FIG. 4, in the retracted state in which the switching operation body 40 is pulled out rearward as shown in FIG. 4, the drive end 39 is separated from the passive flange 36, so that the bearing member 17 is on the cam surface of the shift drum 13. versus Forward and backward is restricted in position, can rotate the dial ring 10 freely as needed, thus functions as a free conversion type that can be converted release code.

図５のように押しボタン３８を押し込むと、その押し込む過程において先端の傾斜押圧面３９ａが傾斜受面３６ａに案内されつつ、切換用操作体４０の駆動端３９により受動鍔部３６をコイルばね２０に抗して上方へ押動し、これによりクラッチ１５とダイヤルリング１０とが図６（ａ）の縦断側面図ように係合してその係合関係が継続され、ダイヤルリング１０の単独回転が阻止されるから、解錠符号の変換が不可能となる関係上、符号固定型として機能させることができ、なお必要に応じ押しボタン３８を引き出すと、切換用操作体４０は後退し、解錠符号の変換が可能な自由変換型として機能させることができる。  When the push button 38 is pushed in as shown in FIG. 5, the inclined pressing surface 39 a at the tip is guided to the inclined receiving surface 36 a in the pushing process, and the passive flange portion 36 is moved to the coil spring 20 by the driving end 39 of the switching operation body 40. The clutch 15 and the dial ring 10 are engaged with each other as shown in the vertical side view of FIG. 6A, and the engagement relationship is continued. Therefore, when the unlocking code cannot be converted, it can be made to function as a code-fixed type, and when the push button 38 is pulled out as necessary, the switching operation body 40 moves backward and unlocks. It can function as a free conversion type capable of code conversion.

符号固定型と自由変換型との切り換え操作のための機構については、例えば図８のように切換用操作体４０の基部に近くプラグ４１により片側が閉塞された段付きの受孔４２を設けると共に、受孔４２にはコイルばね４３の下敷きのもとに段付きのロックピン４４をその先細の先端が外方に進出する傾向に収容し、符号固定型として使用する場合は、図８（ａ）のようにロックピン４４を指頭により押し込んだ後、押しボタン３８を図８（ｂ）のように内方へ押し込み進出させ、また自由変換型に変更して使用する場合には、図８（ｂ）の状態から押しボタン３８をそのロックピン４４が図８（ａ）のようにすべり軸受け３７の端縁よりも後部において突出まで引き出し、ロックピン４４による押し込みが阻止される状態にする。なお切り換え操作のための機構については、上記に限らず種々の構造を採択することが可能である。  As for the mechanism for switching operation between the fixed code type and the free conversion type, for example, as shown in FIG. 8, a stepped receiving hole 42 close to the base of the switching operating body 40 and closed on one side by a plug 41 is provided. In the receiving hole 42, a stepped lock pin 44 is accommodated under the coil spring 43 so that its tapered tip tends to advance outward, and when used as a code fixing type, FIG. ), The push button 38 is pushed inward as shown in FIG. 8 (b), and when it is used by changing to the free conversion type, as shown in FIG. From the state of b), the push button 38 is pulled out until the lock pin 44 protrudes at the rear part from the edge of the slide bearing 37 as shown in FIG. 8A, so that the push-in by the lock pin 44 is prevented. The mechanism for the switching operation is not limited to the above, and various structures can be adopted.

前記シフトドラム１３についてその回転角度に対応して９０度の範域にストッパ４５を設けるのがよく、また図示しないが駆動腕２６についてもその旋回角度に対応して１３５度の範域にストッパを設けるのがよい。  The shift drum 13 is preferably provided with a stopper 45 in the range of 90 degrees corresponding to the rotation angle, and although not shown, the drive arm 26 is also provided with a stopper in the range of 135 degrees corresponding to the turning angle. It is good to provide.
