[Industrial applications]

この考案は、キャッチロックを施錠するための構造に関する。 The present invention relates to a structure for locking a catch lock.

【０００２】[0002]

[Prior art]

従来、キャッチレバーと受け金具とからなるキャッチロックにおいて、これら両者を係合させ、南京錠を使用して施錠する技術は、公知ないし周知である。例えば実公平４ー３９５９９号公報には、受け金具と、その受け金具に掛合させるための掛け金を備えた操作レバーとからなるキャッチロックを筺体用蓋止金具として使用し、南京錠によって操作レバーの自由な動きを封じ、それによりキャッチロックを施錠状態にする技術が開示されている。また、キャッチレバーにシリンダー錠を埋め込み、キャッチレバー外方からの鍵による操作でシリンダー先端部に設けた爪金具を旋回して筺体側の所要部位に係合させ、キャッチロックを施錠する技術は周知である。 Conventionally, in a catch lock composed of a catch lever and a receiving metal fitting, a technique of engaging both of them and locking them by using a padlock is publicly known or well known. For example, in Japanese Utility Model Publication No. 4-39599, a catch lock consisting of a receiving metal fitting and a latch for engaging with the receiving metal fitting is used as a lid stopper for the housing and operated by a padlock. A technique has been disclosed in which the free movement of the lever is sealed, thereby locking the catch lock. In addition, a technology that locks the catch lock by embedding a cylinder lock in the catch lever and turning the claw metal fitting provided at the cylinder tip by operating a key from the outside of the catch lever to engage with the required part on the housing side. Is well known.

【０００３】[0003]

[Problems to be solved by the device]

前記従来技術において、キャッチロックを南京錠によって施錠するものは、南京錠を含めたキャッチロック全体が大きなものとなり狭隘な場所で使用したり、小型の筺体に使用したりすることが難しいという問題や、キャッチロックを取付ける対象物が振動を発生するものである場合には南京錠が筺体などにぶつかり騒音の発生源になるという問題がある。また、キャッチレバーにシリンダー錠を埋め込んだキャッチロックでは、それらの問題を解決できても、シリンダー錠の鍵穴の方向を記憶していない限り、キャッチロックが施錠状態にあるか否かを瞬時に判断できず不便であるという問題がある。 In the above-mentioned conventional technology, when the catch lock is locked with a padlock, the whole catch lock including the padlock becomes large, and it is difficult to use it in a narrow place or in a small housing. However, when the object to which the catch lock is attached generates vibration, there is a problem that the padlock hits the housing and causes noise. In addition, a catch lock with a cylinder lock embedded in the catch lever can solve these problems, but as long as the direction of the key hole of the cylinder lock is not memorized, whether the catch lock is locked or not can be determined. There is a problem that it is inconvenient because it cannot be judged instantly.

【０００４】そこで、この考案は、受け金具に係合したキャッチレバーに外方から当接可能な係止部を設けてその係合の解除を不能ならしめることにより前記従来技術の問題を一挙に解決することを課題にしている。In view of the above, the present invention provides a single solution to the problems of the prior art by providing the catch lever engaged with the receiving fitting with a locking portion that can come into contact with the catch lever from the outside so that the engagement cannot be released. The problem is to solve.

【０００５】[0005]

[Means for Solving the Problems]

この考案が前記課題を解決するために手段とするところは、以下のとおりである。 The points that this device uses as means for solving the above problems are as follows.

【０００６】この考案が前提とするのは、扉や蓋などの可動体に取付けるキャッチレバーと、固定枠などの固定体に取付ける受け金具とからなるキャッチロックを施錠するための構造である。The present invention is premised on a structure for locking a catch lock including a catch lever attached to a movable body such as a door or a lid, and a receiving metal fitting attached to a fixed body such as a fixed frame.

【０００７】かかる前提において、前記キャッチレバーに短径と長径とからなる長円の透孔を設ける。一方、可動体および固定体のいずれかに受け金具に係合した状態のキャッチレバーにおいて前記透孔の外へ延出可能、かつ、延出した状態でその透孔の周方向へ所要角度まわすことが可能な回動軸を設け、回動軸の延出端に前記所要角度まわすとキャッチレバーに外方から当接可能となり前記係合の解除を不能ならしめる前記短径よりも大きくて長径よりも小さい径を有する係止部を設けてあることがこの考案の特徴である。On this premise, the catch lever is provided with an oval through hole having a short diameter and a long diameter. On the other hand, it is possible to extend to the outside of the through hole in the latch lever that is engaged with the receiving metal fitting on either the movable body or the fixed body, and, in the extended state, rotate the required angle in the circumferential direction of the through hole. A rotation shaft that can be rotated is provided, and when the extension end of the rotation shaft is rotated by the required angle, the catch lever can come into contact with the outside from the outside, and it is larger than the short diameter and longer than the short diameter. It is a feature of this invention that a locking portion having a smaller diameter is provided.

【０００８】この考案の実施態様の一つにおいては、前記回動軸にシリンダー錠を使用する。In one of the embodiments of the present invention, a cylinder lock is used on the rotating shaft.

【０００９】[0009]

[Action]

このように構成したキャッチロックを施錠するための構造においては、キャッチレバーを受け金具に係合させると、透孔から回動軸が延出する。その回動軸を所要角度まわすと、回動軸の延出端に設けた係止部の前記透孔の短径よりも大きくて長径よりも小さい部分が透孔の周縁において、外方からキャッチレバーに当接可能となる。その状態において、キャッチレバーを受け金具から離脱させようとしても、その係止部に当接するから、係合を解除することができない。 In the structure for locking the catch lock configured as described above, when the catch lever is engaged with the fitting, the pivot shaft extends from the through hole. When the rotating shaft is rotated by a required angle, the portion of the locking portion provided at the extended end of the rotating shaft that is larger than the minor diameter of the through hole and smaller than the major diameter is outside the peripheral edge of the through hole. It is possible to contact the catch lever. In this state, even if an attempt is made to disengage the catch lever from the metal fitting, the catch lever comes into contact with the engaging portion, so that the engagement cannot be released.

[Effect of device]

この考案に係るキャッチロックの施錠構造においては、キャッチレバーに設けた長円の透孔から延出可能な同じく長円の係止部を回動してキャッチレバーに外方から当接するようにしたから、キャッチロックは外形を比較的小さくすることが可能であり、また、キャッチロックが施錠状態にあるか解錠状態にあるかは、係止部の向きによって一目瞭然となる。係止部は、キャッチレバーに圧接して係止するようにしておくと、扉や固定枠が振動しても、キャッチロックは騒音源になることがない。 In the lock structure of the catch lock according to the present invention, the oval locking portion that can extend from the oval through hole provided in the catch lever is rotated so as to come into contact with the catch lever from the outside. Therefore, the outer shape of the catch lock can be made relatively small, and whether the catch lock is in the locked state or the unlocked state can be seen at a glance depending on the direction of the locking portion. If the locking part is pressed against the catch lever and locked, the catch lock will not become a noise source even if the door or the fixed frame vibrates.
