ていた。Conventionally, in this type of lock, a pin is provided in the lock housing that is pressed by a spring in the direction of retraction, and a recessed hole is provided in the lock plate into which the pin is inserted when the lock is locked, so that the lock plate protrudes when the lock is locked. The condition was maintained.

とにある。The object of this invention is to provide a lock in which the protruding state of the lock plate is maintained by engaging the edge of the leaf spring with the protrusion, and the leaf spring can be supported very easily.

以下、この考案の実施例を添付図面に基いて説明する。Embodiments of this invention will be described below with reference to the accompanying drawings.

ように貫通させたブツシュ−軸８とで構成されている。As shown in the diagram, lock A is installed with lock case 1 and this lock case 1.
Through-holes 2 and 2' are provided at opposing positions on both side walls of the lock plate 3, and the lock plate 3 is assembled into the lock case 1 so as to provide returnability to the lock plate 3. a recessed groove 5 provided on a surface of the lock plate 3 corresponding to the front wall of the lock housing 1 with both ends positioned in the sliding direction of the lock plate 3;
A U-shaped leaf spring 6 faces toward one end of the bushing and is fitted so that one end protrudes from the plate surface of the lock plate 3 to prevent it from coming off through the bent part, and A protrusion 7 provided to engage with one end edge of the plate spring 6 when the lock plate 3 finishes protruding, and a protrusion 7 that provides outward returnability to the front wall of the lock case 1, It consists of a bushing shaft 8 which is passed through the bushing 6 so as to release the engagement therebetween.

９と、この突片９に一端が当接し、かつ他端が錠筐１の
側壁の内面に当接するように上記錠筐１に組込んだバネ
１０とによって行なわれているものを示した。The return property of the lock plate 3 is determined by the protrusion 9 protruding from the side surface of the lock plate 3, and the lock so that one end abuts the protrusion 9 and the other end abuts the inner surface of the side wall of the lock case 1. This is shown by the spring 10 incorporated into the housing 1.

また、凹溝５の側縁に板バネ６の屈曲部が抜けないよう
に支持される膨出部１１をプレスで設けたが、その他の
手段で行なってもよい。Further, although the bulging portion 11 that supports the bent portion of the leaf spring 6 so as not to come off is provided on the side edge of the groove 5 by pressing, other means may be used.

さらに、錠筐１の前面壁に透孔１２を設けて、この透孔

A spring 13 is interposed between the front wall of the lock case 1 and the back surface of the head of the shaft 8 to provide returnability to the shaft 8.

によって吸収することができる。By making the surface of the protrusion 7 on the through-hole 2' side slightly inclined toward the through-hole 2' side, the lock plate 3 can be moved back slightly as one end edge of the leaf spring 6 rotates in an arc. In addition to eliminating such inconveniences, the engagement between the plate spring 6 and the protrusion 7 becomes smooth, and slight dimensional errors in the plate spring 6 can be absorbed by the above-mentioned inclination.

き上記押し戻しが解かれる。The lock according to this invention has the above-mentioned structure, and its use is explained by pressing the terminal end of the lock plate 3, so that the tip side of the lock plate 3 fits into the hole of the mating metal fitting, and locking is performed. However, as the lock plate 3 moves forward, the leaf spring 6 in contact with the protrusion 7 is pushed back into the groove 5, and when one end edge of the leaf spring 6 passes through the protrusion 7, the above-mentioned Pushback is released.

このため、突起７に板バネ６の端縁が係止して錠板３の
突出状態を維持している。Therefore, the edge of the leaf spring 6 is engaged with the protrusion 7 to maintain the protruding state of the lock plate 3.

イドさせる。To unlock the lock plate 3 by sliding it in the retracting direction, push the shaft 8, the edge of the leaf spring 6 comes off from the protrusion 7, and the lock plate 3 is slid in the retracting direction by the spring 10. let

以上のように、この考案に係る錠前によれば、突出方向

突起とが係合して施錠状態を維持することができる。As described above, according to the lock according to this invention, by sliding the lock plate in the protruding direction, the edge of the leaf spring and the protrusion engage with each other to maintain the locked state.

また、軸をブツシュ−すると、突起から板バネの端縁が
