Description
【０００１】[0001]
本考案は主として宝石、時計、貴金属等の貴重品を収納する陳列ケース等のガ ラス戸に取付け、施錠が閉戸によって自動的に行なわれる閉戸による自動施錠装 置に関する。 The present invention mainly relates to an automatic locking device that is attached to a glass door such as a display case that stores precious items such as jewelry, watches, and precious metals and that is automatically locked when the door is closed.
【０００２】[0002]
陳列ケースのガラス戸等に取り付けて使用する錠は、解錠はもとより施錠に際 しても鍵を鍵孔に差し入れて回動操作することによって行なうものが多いため、 その施錠作業自体煩わしいものであり、時には施錠そのものを忘れてしまう虞れ がある等の難点を有していた。 そこで本出願人は上記のような問題を解消するため、戸を閉めることによって 自動的に施錠がなされる自動施錠装置を先に提案した（特開昭５７−８５４６５ 号公報）。この自動施錠装置は錠ケース内に摺動自在に嵌着された摺動体の先端 に突設した錠杆がケース先端の孔から進退自在となっており、解錠時には、その 錠杆が錠杆先端部に設けた係止片による係止によってケース側に後退した（引っ 込んだ）状態にある。そして戸を閉めることにより戸の錠杆用雌孔付近に設けた 突起が上記係止片に接して該係止片による係止を解除し、その結果、上記の錠杆 が前方に突出し上記雌孔に介入することによって自動的に施錠がなされるという ものである。 Most of the locks that are attached to the glass doors of the display case are not only unlocked but also locked by inserting the key into the keyhole and rotating the lock. However, there were some difficulties, such as the possibility of forgetting the lock itself. Therefore, in order to solve the above problems, the present applicant has previously proposed an automatic locking device that automatically locks the door by closing it (Japanese Patent Laid-Open No. 57-85465). In this automatic locking device, a locking rod protruding from the tip of a sliding body slidably fitted in the lock case can be moved forward and backward through a hole at the tip of the case, and when unlocking, the locking rod is locked. It is in the state of being retracted (retracted) to the case side by the locking by the locking piece provided at the tip. When the door is closed, a protrusion provided near the female hole for the locking rod of the door comes into contact with the locking piece to release the locking by the locking piece, and as a result, the locking rod projects forward and the female lock is closed. It is automatically locked by intervening in the hole.

しかしながら上記閉戸による自動施錠装置は、施錠時の錠杆の突出を、ケース 内先端部と摺動体先端部の間に介在固定させた引っ張りバネにより摺動体をケー ス先端側に向けて引っ張るという機構により行なっているため、長期間繰り返し て使用しているうちに引っ張りバネの引張力が弱くなり、それにともなって摺動 体の動きが鈍くなるため錠杆の突出動作もスムーズになされなくなる懸念がある 。また、このような現象は引っ張りバネ自体がへたった時、そのへたったバネが 摺動体の進路をばむむため特に顕著となることが予想される。 本考案は上記自動施錠装置を更に改良したもので、施錠時の錠杆の突出動作が 常に、しかも長期にわたっても機敏で且つ安定してなされるという、より高性能 な閉戸による自動施錠装置を提供することを目的とする。 However, in the automatic locking device with the above door, the protrusion of the locking rod during locking is pulled by the extension spring fixed between the tip of the case and the tip of the sliding body toward the tip of the case. Since this is done by a mechanism, the tensile force of the tension spring weakens during repeated use over a long period of time, and the movement of the sliding body becomes slower accordingly, so there is a concern that the protruding motion of the locking rod will not be smooth. is there . Moreover, it is expected that such a phenomenon will be particularly remarkable when the tension spring itself is bent and the bent spring obstructs the path of the sliding body. The present invention is a further improvement of the above-mentioned automatic locking device, and provides a higher-performance automatic locking device with a closed door, in which the locking rod protruding operation during locking is always agile and stable over a long period of time. The purpose is to provide.

A sliding body 6 having a structure in which a sliding body front portion 6a is installed so that an engaging notch portion 28 is engaged with a guide protrusion 27 having a groove is employed (see FIG. 7C), and the sliding body 6 is used as a case. It may be fitted in the main body 9. The front portion 6a of the sliding body is slidable on the guide protrusion 27.
【００１１】 次に本考案装置の作用について説明する。 本考案装置は開閉戸の一方の戸体30に錠本体１を取付け、他方の戸体31に被施 錠具２を取付けて使用する。 まず解錠に当たっては、シリンダー錠５の鍵穴13に鍵（図示せず）をさし込ん で右回りに回動させることにより、摺動体６とともに錠杆４が右回りに回動しな がら後退し、係止片３の係止によって位置も固定される（図６参照）。即ち、鍵 による回動操作により、シリンダー錠５を内蔵した摺動体６が一体的に右方向に 回動すると同時にガイド溝20に制御されてケース本体の後端側に後退するため、 錠杆４も同様にして右に回動しながら後退する。そして錠杆４が回動して係止片 ３が係止溝８の位置までくると、係止片３はバネ部材18により突出して係止溝８ 内に介入し、これにより錠杆４（及び摺動体６）が後退した状態で位置固定され る。なお、この時点で押圧バネ10は圧縮された状態となる。Next, the operation of the device of the present invention will be described. The device of the present invention is used by attaching the lock body 1 to one door body 30 of the opening / closing door and attaching the locked tool 2 to the other door body 31. First, when unlocking, insert a key (not shown) into the key hole 13 of the cylinder lock 5 and rotate it clockwise so that the slide rod 6 and the lock rod 4 move backward while rotating clockwise. However, the position is also fixed by the locking of the locking piece 3 (see FIG. 6). That is, since the sliding body 6 incorporating the cylinder lock 5 integrally rotates to the right by the turning operation by the key, and at the same time, the sliding body 6 is controlled by the guide groove 20 and retracts to the rear end side of the case body, In the same manner, it rotates backward to the right and moves backward. When the locking rod 4 is rotated and the locking piece 3 reaches the position of the locking groove 8, the locking piece 3 is projected by the spring member 18 and intervenes in the locking groove 8, whereby the locking rod 4 ( And the sliding body 6) is fixed in the retracted state. At this point, the pressing spring 10 is in a compressed state.
【００１２】 また施錠に当たっては、戸体31を図６中の矢印Ｐ方向に閉めることにより、被 施錠具２の突出部22が係止片３の先端に接触し、係止片を係止溝８側から錠杆４ の凹溝16側に押圧するため、それにより係止片３による係止が解かれる。この係 止の解除と同時に、圧縮状態にある押圧バネ10の復元押圧力により摺動体６が押 されてガイド溝20に再び制御されつつ左回りに回動しながら出入孔７側へ瞬時に して移動するため、錠杆４が出入孔７から突出し、その先端が被施錠具２の雌孔 21内に介入し、以て施錠がなされる（図７参照）。 施錠は戸体30を図６中の矢印Ｑ方向に閉めることによっても同様になされる。 尚、図７における係止片３は本来、摺動体６(a) が図６に図示の位置からガイド 溝20にガイドされて左回りに回転して出入孔７側に移動することから、例えば図 ４（Ａ）に図示の如き位置（状態）にあるべきはずであるが、これは係止片３が 施錠時における凹部16に収納されている様子を明確にするため、便宜上、事実に 相応しない状態で図示したものである。When locking, by closing the door body 31 in the direction of arrow P in FIG. 6, the projection 22 of the locked tool 2 contacts the tip of the locking piece 3 and the locking piece is locked. Since it is pressed from the 8 side toward the concave groove 16 side of the lock rod 4, the locking by the locking piece 3 is released thereby. Simultaneously with the release of this lock, the sliding body 6 is pushed by the restoring pushing force of the pushing spring 10 in a compressed state, and is controlled by the guide groove 20 again and is rotated counterclockwise while being instantaneously moved to the entrance / exit hole 7 side. The lock rod 4 projects from the entrance / exit hole 7, and the tip of the lock rod 4 intervenes in the female hole 21 of the to-be-locked tool 2 to lock it (see FIG. 7). The locking is performed in the same manner by closing the door body 30 in the direction of arrow Q in FIG. The locking piece 3 in FIG. 7 originally moves the sliding body 6 (a) from the position shown in FIG. 6 to the entrance / exit hole 7 side by being guided by the guide groove 20 and rotating counterclockwise. It should be in the position (state) as shown in Fig. 4 (A), but this is for the sake of convenience to clarify the fact that the locking piece 3 is housed in the recess 16 at the time of locking. It is illustrated in a state where it is not.
【００１３】 図６及び図７に図示の錠本体１における摺動体６及び押圧バネ10は、図４に例 示した形態のものである。この形態の場合、解錠時に鍵によりシリンダー錠５を 右方向に回動すると、まず摺動体後部６ｂがガイド溝26により制御されつつ定位 置で右回転し、この摺動体後部６ａの回転が一端を該後部６ｂに固定した螺旋状 に巻いた押圧バネ10を右回りに巻き締め、これによりバネ10が摺動体後部６ｂ側 に巻き縮められる。その結果、このバネ10の他端を連結固定してなる摺動体前部 ６ａが右方向に回動しガイド溝26に制御されつつ後退する。一方、施錠に当たっ ては閉戸によって係止片３の係止が解除されると、巻き縮められた押圧バネ10が 左回りに巻き戻りながら摺動体前部６ａを出入孔７側に瞬時的に押すため、錠杆 ４が突出して施錠される。The sliding body 6 and the pressing spring 10 in the lock body 1 shown in FIGS. 6 and 7 are in the form illustrated in FIG. In the case of this form, when the cylinder lock 5 is rotated to the right by the key at the time of unlocking, the rear part 6b of the sliding body is first rotated in the fixed position while being controlled by the guide groove 26, and the rear part 6a of the sliding body is rotated once. The pressing spring 10 fixed in the rear portion 6b is wound in a clockwise direction, and the spring 10 is contracted to the rear portion 6b side of the sliding body. As a result, the sliding body front portion 6a formed by connecting and fixing the other end of the spring 10 pivots to the right and retracts while being controlled by the guide groove 26. On the other hand, in locking, when the locking piece 3 is unlocked by closing the door, the compressed spring 10 is retracted counterclockwise while the sliding body front part 6a is momentarily moved to the exit / entry hole 7 side. Since it is pushed to, the locking rod 4 is projected and locked.
【００１４】 摺動体６が図４の如き摺動体前部６ａと摺動体後部６とから構成されるもの場 合、その両者間に介在させて連結させる押圧バネ10としては解錠時の鍵の回動操 作方向に回転を与えたとき、巻き縮むタイプのものを使用する必要がある。また 図３の如き形態の摺動体及び押圧バネにより錠本体１を形成すると、シリンダー 錠５の規格サイズ制限により小径胴部24の部分のサイズを小さくできないため隙 間23の分だけケース本体のサイズ（直径）を大きくしなければならないが、図４ の如き形態の摺動体及び押圧バネにて錠本体１を形成してやれば、そのような不 都合がない利点がある。When the sliding body 6 is composed of the sliding body front portion 6a and the sliding body rear portion 6 as shown in FIG. 4, the pressing spring 10 which is interposed between the sliding body 6a and the sliding body rear portion 6 and is connected is a key for unlocking. It is necessary to use a type that shrinks when given rotation in the direction of rotation operation. When the lock body 1 is formed by the sliding body and the pressing spring having the configuration as shown in FIG. 3, the size of the small diameter body portion 24 cannot be reduced due to the standard size limitation of the cylinder lock 5, and the size of the case body is reduced by the space 23. The (diameter) must be increased, but if the lock body 1 is formed by the sliding body and the pressing spring having the configuration shown in FIG. 4, there is an advantage that there is no such inconvenience.
【００１５】 また図４に例示の錠本体に対する変形態様である図５に図示の錠本体によれば 、開錠時にシリンダー錠５を右回りに回すと、摺動体後部６ｂがガイド溝26によ り制御されつつ定位置で右回転するため、それによりガイド突片27に係合されて いる摺動体前部６ａも右方向に回動しガイド溝26に制御されつつ、ケース本体内 面とガイド突片27上を摺動しながら後退し、係止片３が係止溝８に嵌合係止され た時点で固定される（図５（Ｂ））。この時点で押圧バネ10は圧縮された状態と なる。 そして施錠に当たっては閉戸によって係止片３の係止が解除されると、圧縮さ れた押圧バネ10が弾性復元するため摺動体前部６ａが出入孔７側に瞬時的に押さ れ、以て錠杆４が突出して施錠される（図５（Ａ））。このとき同時にガイド突 片27を介して摺動体後部６ｂも左回りに回動する。According to the lock body shown in FIG. 5 which is a modification of the lock body illustrated in FIG. 4, when the cylinder lock 5 is rotated clockwise when unlocked, the sliding body rear portion 6b is guided by the guide groove 26. Since it rotates to the right at a fixed position while being controlled, the front portion 6a of the sliding body, which is engaged with the guide protrusion 27, also rotates to the right and is controlled by the guide groove 26, and the inner surface of the case body and the guide It slides on the protruding piece 27 and moves backward, and is fixed when the locking piece 3 is fitted and locked in the locking groove 8 (FIG. 5 (B)). At this point, the pressing spring 10 is in a compressed state. In locking, when the locking piece 3 is unlocked by closing the door, the compressed pressing spring 10 elastically restores, so that the sliding body front portion 6a is instantaneously pressed to the entrance / exit hole 7 side.

以上説明したように、本考案装置は前記の如く錠本体における摺動体を押圧バ ネによって付勢し、施錠時に摺動体がケース本体の先端側に移動するよう構成し ているため、引っ張りバネを採用している従来品に比べ、バネ力の低下が少なく 一定して摺動体を押すため施錠時における錠杆の突出動作がきわめてスムーズに 行なわれる。また押圧バネによる摺動体への付勢方式を採用したことにより、上 記従来品の如く引っ張りバネを収納していたケース本体内部先端部と摺動体先端 部間のスペースＹ（図６参照）内にバネ部材が存在しなくなるため、施錠におい てケース先端側に押される摺動体の進路がバネ部材によって阻害される虞れがな くなり、これによっても効率のよい錠杆の突出動作がなされる。 As described above, the device of the present invention is configured such that the sliding body in the lock body is urged by the pressing vanes as described above and the sliding body moves to the tip side of the case body when locking, so that the tension spring is Compared with the conventional products used, the spring force is less reduced and the sliding body is pushed constantly, so the locking rod can be ejected very smoothly during locking. In addition, by adopting the biasing system to the sliding body by the pressing spring, inside the space Y (see Fig. 6) between the tip of the sliding body and the inside of the case body that accommodates the tension spring as in the conventional products described above. Since the spring member does not exist in the lock, there is no fear that the spring member will obstruct the path of the sliding body that is pushed to the tip side of the case during locking, and this also enables efficient protrusion of the locking rod. ..
