Description
【考案の詳細な説明】 本考案は文字合わせ錠に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a character matching lock.
（従来の技術） 従来、この種の文字合わせ錠は第１２図に示すようなも
のがある。(Prior Art) Conventionally, there is a character matching lock of this kind as shown in FIG.
これは、回転板３′の回転により外リング５′の切欠溝
２０と内筒２′の切欠溝１７を合致させて、それらをラ
ッチ９′と同一平面上に回動して解錠するものである。This is to make the cutout groove 20 of the outer ring 5'and the cutout groove 17 of the inner cylinder 2'match by the rotation of the rotary plate 3'and rotate them in the same plane as the latch 9'to unlock. Is.
またこれは、ラッチ９′が施錠時と解錠時にともに外筒
１′内に収没するように、該ラッチ９′にあけた長孔９
ａ′に回転軸を挿入して上下スライド及び回転動作を行
っていた。Further, this is a long hole 9 formed in the latch 9'so that the latch 9'is retracted into the outer cylinder 1'when locked and unlocked.
The rotary shaft was inserted into a'and the vertical sliding and rotating operations were performed.
（考案が解決しようとする課題） ところがこれは第８図に示すように、外リングの回転を
被駆動爪と回転板の駆動爪で行うため、解錠する際に左
回しで始めた時と右回しで始めた時とは駆動爪及び被駆
動爪の厚さ分の誤差がでて解錠番号が夫々異なってしま
う。(Problems to be solved by the invention) However, as shown in FIG. 8, this is because the outer ring is rotated by the driven claw and the driving claw of the rotating plate, so There is an error in the thickness of the driving claw and the driven claw from that when starting by turning clockwise, and the unlocking numbers are different.
そこで、従来はこの誤差を解消して解錠するために、解
錠時における回転板の初めの回転方向を必ず左右のどち
らか一方に決めていた。Therefore, conventionally, in order to eliminate this error and unlock, the initial rotation direction of the rotating plate at the time of unlocking is always determined to be either left or right.
そのため、使用者は常に解錠番号とともに回転板の初め
の回転方向、即ち「右」か「左」かを覚えていなければ
ならず非常に面倒であった。Therefore, the user must always remember the unlocking number and the initial rotation direction of the rotary plate, that is, "right" or "left", which is very troublesome.
また、従来はラッチに長孔をあけていたため、形成が非
常に困難で手間を要するとともに、該長孔の左右の肉厚

転体５の回転で内タンブラ３が回転するとともに、調整
リング４を介して外タンブラ２が回転して夫々後部に切
欠した長溝２ｂ、３ｂ同志が合致される。That is, the width of the engaging recess 4a in the adjusting ring 4 is
By setting the width of at least the claw piece 4b of the adjustment ring 4 and the hooking portion 2c of the outer tumbler 2 to match, the engaging claw 5a
Also, the error due to the wall thickness of the hook portion 2c can be eliminated, and the same unlocking number can be set by rotating the rotating body 5 in either the left or right direction. Then, the inner tumbler 3 is rotated by the rotation of the rotating body 5 caused by the rotation operation of the rotary knob 5c, and the outer tumbler 2 is rotated via the adjusting ring 4 so that the long grooves 2b and 3b cut out at the rear are aligned with each other.
また外筒１の後部には、前記外タンブラ２及び内タンブ
ラ３の後端に、先端部が接するようにラッチホルダ６が
嵌入されている。Further, a latch holder 6 is fitted to the rear part of the outer cylinder 1 at the rear ends of the outer tumbler 2 and the inner tumbler 3 so that the front ends are in contact with each other.
ラッチホルダ６は中央部に上面から下面にかけて貫通し
た貫通孔８が設けられるとともに前面には貫通孔８と、
内外タンブラ２、３の長溝２ｂ、３ｂとを連結する連通
溝８ｃが設けられ、該貫通孔８にはラッチ７が上下動自
在に収容されている。The latch holder 6 is provided with a through hole 8 penetrating from the upper surface to the lower surface in the central portion and the through hole 8 on the front surface.
A communication groove 8c for connecting the long grooves 2b, 3b of the inner and outer tumblers 2, 3 is provided, and a latch 7 is housed in the through hole 8 so as to be vertically movable.
また貫通孔８の両側面又は一側面には縦溝９が中間部か

面上に合わされる。Thus, the character matching lock A is used as shown in FIG. 5, the latch 7 abuts the projection n of the box B to close the lid m when locked, and the rotary knob 5c when unlocked. After rotating the wheel to the left or right, by changing the rotation direction alternately and setting it to the unlocking number, the outer tumbler 2 and the inner tumbler 3
The long grooves 2b and 3b are aligned with each other and are aligned with the latch 7 on the same plane.
そして蓋ｍを手前に引くと、ラッチ７が回転軸９ａを中
心にして後方へ回転して外筒１内へ収没することにより
解錠されて蓋ｍが開放される。Then, when the lid m is pulled toward you, the latch 7 rotates backward around the rotation shaft 9a and retracts inside the outer cylinder 1 to be unlocked and the lid m is opened.
次に閉塞するときは、蓋ｍを箱体Ｂ側へ押すことにより
突起片ｎがラッチ７の湾曲状の傾斜部７ｄに当接してラ
ッチ７が下側にスライドされて外筒１内に収没されて突
起片ｎに係止される。Next, when closing, by pushing the lid m toward the box B side, the protruding piece n comes into contact with the curved inclined portion 7d of the latch 7 and the latch 7 is slid downward and is housed in the outer cylinder 1. It is submerged and locked by the protruding piece n.
この時ラッチ７はまだ後方へ回転可能な状態であるの
で、回転摘み５ｃを任意に回転させて外タンブラ２およ
