Description

【考案の詳細な説明】本考案はシヤツター等に用いるラツチ錠匣の固
定装置に関する。[Detailed Description of the Invention] The present invention relates to a fixing device for a latch lock case used in a shutter or the like.

従来この種のラツチ錠の取付けは、第１図に示

を傷つける欠点があつた。 Conventionally, when installing this type of latch lock, as shown in FIG.
The flat bottom plate c (mounting side surface) of the latch lockbox b is stacked and one end of the bottom surface c is fixed to the mounting surface a with a rivet d. It may lift up due to "shaking" during flat finishing or installation and fixing work, etc.
A gap is created between the mounting surface a and the bottom plate c, and a deviation occurs in the height of the lock case b from the mounting surface a, making it difficult for the latch piece to slide, that is, the lock operation, and for the slat to become loose when winding up the shutter. It had the disadvantage of scratching and damaging the top plate.

従つて取付け面と錠匣ｂの規定の高さを保持さ
せるため、第３図に示すように底板ｃの上下を延
出し、この上下の延出部をリベツトで固定してい
る。しかしリベツト作業等で作業性に乏しく、し
かも外観を損う欠点がある。 Therefore, in order to maintain a specified height between the mounting surface and the lock case b, the top and bottom of the bottom plate c are extended as shown in FIG. 3, and these upper and lower extensions are fixed with rivets. However, it has the disadvantage of poor workability due to riveting work, etc., and furthermore, it spoils the appearance.

本考案は斯様な点を鑑み、この問題を解決する
ことを目的としたものである。 In view of these points, the present invention aims to solve this problem.

即ち、錠匣の取付面側の底板を予め屈折させ、
底板を取付け面に当て、底板を取付け面に固定す
ることにより、変形しなじみ易い薄板の特性と相
俟つて両者間に適当なテンシヨンを働かせて両者
を密着させるものである。 That is, the bottom plate on the mounting surface side of the lock case is bent in advance,
By applying the bottom plate to the mounting surface and fixing the bottom plate to the mounting surface, an appropriate tension is exerted between the two, combining the characteristics of the thin plate which easily deforms and conforms, to bring the two into close contact.

以下本考案に係るラツチ錠匣固定装置の一実施
例添付図面に基いて具体的に説明する。 DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the latch lock box fixing device according to the present invention will be described in detail below with reference to the accompanying drawings.

１はラツチ片２及びこのラツチ片２を作動する
作動機構を組込んだ錠匣で、錠匣１に一端を摺嵌
した摺動片３の左右の摺動でラツチ片２を作動機
構を経て作動する。 1 is a lock case incorporating a latch piece 2 and an operating mechanism for operating the latch piece 2; one end of the sliding piece 3 is slid into the lock case 1, and the latch piece 2 is moved through the operating mechanism by sliding from side to side. Operate.

錠匣１の底板１′は予め適当な角度をもつて屈
折加工してある。前記錠匣１の底板１′は、スラ
ツト４の端部近旁の取付け面４′に当て錠匣１か
ら上部に向けて延出させ、この延出部１″を、取
付け面４′にリベツト等の固定具５で締結させ
る。 The bottom plate 1' of the lock case 1 is bent in advance at an appropriate angle. The bottom plate 1' of the lock case 1 is applied to the mounting surface 4' near the end of the slat 4 and extends upward from the lock case 1, and this extending portion 1'' is attached to the mounting surface 4' by a rivet or the like. Fasten with the fixing tool 5.

前記の構成で明らかなように、スラツト４の取
付け面４′に対して適当に屈折させた錠匣１の底
板１′を当て、底板１′の錠匣１からの延長部１″
を取付け面４′に固定具５で締結して取付ける
が、この時底板１′は、薄板の変形しなじみ易い
特性と相俟つて取付け面４′と底板１′間に適度の
テンシヨンが働き密着して固定できる。 As is clear from the above structure, the bottom plate 1' of the lock case 1, which is bent appropriately, is applied to the mounting surface 4' of the slat 4, and the extension part 1'' of the bottom plate 1' from the lock case 1 is
At this time, the bottom plate 1' is attached to the mounting surface 4' by fastening it to the mounting surface 4' with the fixing device 5. At this time, due to the thin plate's tendency to deform and conform, an appropriate tension is exerted between the mounting surface 4' and the bottom plate 1', and the bottom plate 1' is tightly attached. It can be fixed by

従つてその結果次の効果がある。 Therefore, the following effects are obtained as a result.

ａ組立時の高さ即ち、スラツト取付け面から錠
匣の高さは、底面を適当な角度をもつて屈折し
て、これをスラツト取付け面に固定具で締結す
るので従来のように平坦面の仕上げに左右され
ないですむ。a The height when assembled, that is, the height of the lockbox from the slat mounting surface, is determined by bending the bottom at an appropriate angle and fastening it to the slat mounting surface with a fixture, so it is different from the conventional flat surface. It doesn't depend on the finish.

ｂ底面の屈折により錠匣に対する固定部を中心
とした他方からの開き方向の外力に強く、反対
に外力を利用して錠匣１を取付け面４′に押し
付け密着性する。(b) Due to the bending of the bottom surface, it is strong against external force in the opening direction from the other side centering on the fixing part to the lock case, and on the other hand, the external force is used to press the lock case 1 against the mounting surface 4' for tight contact.

ｃ従来では、取付け面と錠匣底板との間に隙間
ができるため、これをなくすため上下端部をリ
ベツト等により固定していたが、底板を屈折さ
せることで一端だけの固定でよく、煩わしさが
なく、外観も損じない。c Conventionally, there was a gap between the mounting surface and the bottom plate of the lock case, so in order to eliminate this gap, the top and bottom ends were fixed with rivets, etc., but by bending the bottom plate, only one end needs to be fixed, which eliminates the hassle. No sagging and no damage to appearance.

ｄエンボススラツトにも取付けた時安定する。d Stable when installed on embossed slats.
