夛）る。In the figure, numeral 36 denotes a door frame, and numeral 37 denotes a locking metal fitting, which is attached to the door frame and locks the bent end 10 of the lock piece 5.

次に本考案の作用・効果を上記実施例によって説明する
。Next, the functions and effects of the present invention will be explained using the above embodiments.

ます本錠の製造に関してはトリガ一部片用の特別の空間
・構造を形成する必要かなく、また組込み時において、
トリガ一部片６は錠箱１自体の両側板３，３のガイド部
１８．１８に係合させればよい。Regarding the manufacture of this lock, there is no need to create a special space or structure for the trigger piece, and when assembling it,
The trigger piece 6 may be engaged in guide portions 18, 18 of the side plates 3, 3 of the lockbox 1 itself.

その際に上記実施例では、ガイド部１８．１８の後部に
連続する組込用孔２０，２０を形成しであるので、錠箱
１の後方から短突片１５．１５が上下位置を向く状態で
挿入し、組込用孔２０．２０の位置で９０°回動させて
短突片１５，１５を該孔２０，２０に係合させ、そのま
ま前進させればよい。At this time, in the above embodiment, the continuous installation holes 20, 20 are formed at the rear of the guide portion 18.18, so that the short protrusion 15.15 faces upward and downward from the rear of the lock box 1. 20, rotated by 90 degrees at the position of the assembly hole 20, 20 to engage the short protrusions 15, 15 with the holes 20, 20, and then just move forward.

これにより先部が前板２の孔１７から突出するとともに
、短突片１５，１５がガイド部１８．１８に係合するこ
とになる。This causes the tip to protrude from the hole 17 in the front plate 2, and the short protrusions 15, 15 to engage with the guide part 18.18.

なおりリック用バネ８を上記実施例の如く構成してあれ

付は易いとともに、それをスライド板７のクリック用短
棒３０と組合せるのも錠箱１外にて両側線２８．２９間
に短棒３０を係合させてスライド板７を錠箱１内に収容
すればよいので、その組込みが非常に容易である。If the click spring 8 is configured as in the above embodiment, it is installed near the rear of the lock box 1, so it is easy to install, and it can be connected to the short click bar 30 of the slide plate 7. Assembling can be done by simply engaging the short rod 30 between the wires 28 and 29 on both sides outside the lock box 1 and housing the slide plate 7 inside the lock box 1, so the assembly is very easy.

次に解錠しようとする際は、内側の手掛用側面板３２の
つまみ３４を上方にスライドさせればよい。The next time you want to unlock the door, just slide the knob 34 on the inner handle side plate 32 upward.

すると操作板３５内側の作動部片２５が錠箱の窓部２６
，２６を介してスライド板７の作動用部２４゜２４に係
合しているので、該スライド板７を上方にスライドさせ
る。Then, the operating piece 25 inside the operating panel 35 moves to the window 26 of the lockbox.
, 26, the slide plate 7 is slid upward.

これにより、第１図スライド板７の可動軸用凹欠部２１

その屈曲先部１０を戸枠３６の係合金具３７から離脱さ
せて錠箱１内へ収納する。As a result, the movable shaft recess 21 of the slide plate 7 in FIG.
, 21 engages therein, the movable shaft 13 is inserted into the curved hole 1 of the lock box.
4. Pull it up along line 14, and at that time, since the movable shaft 13 is engaged with the diagonal hole 12 at the rear of the lock piece 5, rotate the iron piece 5,
The bent end portion 10 is separated from the engagement fitting 37 of the door frame 36 and stored in the lock box 1.

この場合）・リガ一部片６は、第１図・第４図の如くそ

９，１９で係止されている。In this case), the rigger piece 6 is pushed by the spring 16 when the slide plate 7 rises and the short protrusions 15, 15 of the rigger piece 6 disengage from the engaging parts 23, 23 of the iron plate 7, as shown in FIGS. 1 and 4. move forward, and with the tip protruding from the front mounting plate 2, remove the short protruding pieces 15,
15 is the front edge 1 of the guide portion 18.18 of the lock box side panels 3, 3
It is locked at 9 and 19.

またクリック用バネ８は、スライド板７上昇時に中間位
置で鉄板７のクリック用短棒３０がクリック用バネ８の
屈曲部３１をバネ力に抗って通過するのでクリック作用
を及は゛している。Further, the click spring 8 exerts a click action because the short click bar 30 of the iron plate 7 passes through the bent portion 31 of the click spring 8 at an intermediate position while resisting the spring force when the slide plate 7 is raised.

なおこの解錠時には、前記の如くトリガ一部片６が前方

であり、不用意に戸を閉めても錠片５が戸枠３６の係止
金具３７に衝突することはない。When unlocking, the trigger piece 6 protrudes forward as described above, and the lower locking edges 22, 22 of the slide plate 7 are locked by the short protrusions 15, 15, so that the trigger piece 6 can be used for operation. Even if the knob 34 is held down, the slide plate 7 does not come down, so the bent end 10 of the lock piece 5 remains housed in the lock box 1, and even if the door is closed carelessly, the lock piece 5 does not fall into the door frame. It will not collide with the locking fitting 37 of 36.

そして施錠する場合は、戸を閉めることによりまず取付
用前板２の前方へ突出している１〜リガ一部片６が、戸
枠３６の係止金具３７前面に当接してバネ１６に抗って
後退する。When locking the door, firstly, by closing the door, the parts 1 to 6 of the riggers protruding forward of the front mounting plate 2 come into contact with the front surface of the locking fitting 37 of the door frame 36 and resist the spring 16. and retreat.

これにより第２図の如く、スライド板７の係止用下縁２
２ 、２２は自動的にトリガ一部片６の短突片１５，１

2, 22 are automatically connected to the short protrusions 15, 1 of the trigger piece 6.
5, and the longitudinal retaining portion 23.23 is removed from the short protrusion 1.
5 and 15, so when the operating knob 34 of the hand side plate 32 is pushed down, the slide plate 7 is lowered via the operating piece 25.

従って該スライド板７の凹欠部２１，２１に係合する可
動軸１３が彎曲状孔１４．１４に沿って降下し、錠片５
の後部を斜孔２２を介して押下げるので、錠片５は回動

係止金具３７に係止され施錠されることになる。Therefore, the movable shaft 13 that engages with the recessed portions 21, 21 of the slide plate 7 descends along the curved hole 14, 14, and the lock piece 5
As the rear part of the door is pushed down through the diagonal hole 22, the lock piece 5 rotates and the bent tip 10 protrudes from the front mounting plate 2, and is locked by the locking fitting 37 of the door frame 36. .

この場合トリガ一部片６は、第２図・第５図の如く前記
の如く後退しスライド板７の係止部２３，２３内でその
前縁にて係止されている。In this case, the trigger piece 6 is retracted as described above, as shown in FIGS. 2 and 5, and is locked at its front edge within the locking portions 23, 23 of the slide plate 7.

またクリック用バネ８は、スライド板７降下時に中間位
置で短棒３０がバネの屈曲部３１をバネ力に抗って通過
するので、クリック作用を及ぼしている。Further, the click spring 8 exerts a click action because the short rod 30 passes through the bent portion 31 of the spring at an intermediate position against the spring force when the slide plate 7 is lowered.

以上で明かな如く本考案に係る引違い戸用錠は、近時厚
み幅が薄くなるアルミサツシ戸に取付可能なように、錠
の厚みを薄くできるとともに、構造を簡素化し部品数を
減らし、かつ組込作業も容易・迅速に行えるようになっ
た。As is clear from the above, the lock for sliding doors according to the present invention can be made thinner so that it can be installed on aluminum sash doors, which have become thinner in recent years, and has a simplified structure and reduced number of parts. Installation work can now be done easily and quickly.

即ち、従来のこの種の錠では薄型のものは殆んど無った
し、また構造上から薄型化を図ることはできないか、ま
たは極めて困難であり、さらに組込作業が困難であった
。That is, there are almost no conventional locks of this type that are thin, and it is either impossible or extremely difficult to make the locks thinner due to the structure, and furthermore, it is difficult to assemble the locks.

しかし本考案では上記の如くトリガ一部片を錠箱内の、
しかもスライド板の内側に設け、錠箱とスライド板の孔
および凹欠部内で作動せしめるので、従来のように錠本
体以外に特別にトリガ一部片用の空間・機構を必要とし
ない。However, in the present invention, as mentioned above, a part of the trigger is placed inside the lock box.
Furthermore, since it is provided inside the slide plate and operated within the hole and recessed portion of the lock box and slide plate, there is no need for a special space or mechanism for a trigger piece other than the lock body, unlike in the conventional case.

またその組込みも構造が簡素化し部品数が少くなったの
で容易であるが、上記実施例の如く錠箱にトリガ一部片
組込用孔を形成してあれば、錠箱内への組込みは一層容
易・迅速となる。Also, it is easy to assemble it because the structure is simplified and the number of parts is reduced, but if the hole for assembling the trigger piece is formed in the lock box as in the above embodiment, it can be assembled into the lock box. It becomes easier and faster.

なお上記実施例の如くクリック用バネを錠箱後部寄りに
設け、屈曲部付の両側線間でスライド板の短棒を挾持さ
せであると、従来錠箱中央部にある構成のため組込みが
難しかったクリック用バネの組込みが容易であるととも
に、スライド板との関係も錠箱外で組合せられるように
なり、この点からも組込作業が容易・迅速にできること
になる。In addition, if the click spring is provided near the rear of the lock box as in the above embodiment, and the short bar of the slide plate is held between the lines on both sides of the bent part, it would be difficult to assemble the click spring because it is conventionally located in the center of the lock box. It is easy to assemble the click spring, and the relationship with the slide plate can be assembled outside the lock box, which also makes the assembling work easier and faster.
