Description

【０００１】
【発明の属する技術分野】
本発明は、扉の木口面に設置されるラッチ錠のラッチを係止するために出入口の縦枠に形成された堀込穴に埋設されるラッチ用受座、殊にラッチの係止位置を横方向に調整可能としたラッチ用受座に関するものである。
【０００２】
【従来の技術】
扉の木口面に設置されたラッチ錠のラッチを係止するために出入口の縦枠に形成された堀込穴に埋設されるラッチ用受座の中で、ピニヨンとラックとの噛合を用いて前後方向の係止位置を調整可能とし、取付調整および取付後に生じるずれの修正を可能な構成としたものを、本願出願人は先に実開平４−１００７７２号で提示している。
【０００３】
この考案は、堀込穴に固定されるベース部材に前後方向へ摺動可能なスライド部材が嵌装されており、これらベース部材とスライド部材との間に上下方向へ移動可能にして斜め方向の傾斜面とラックとを有する移動プレートが挟み込まれており、この移動プレートのラックに、ピニヨンと操作凸部とからなる調整歯車のピニヨンが噛合している、という構成を有している。
【０００４】
そして、スライド部材から突出させた操作凸部を回すと、操作凸部のピニヨンと移動プレートのラックとが噛合していることから、移動プレートが傾斜面に沿って斜め方向に移動することでスライド部材を幅方向へ移動させて、係止位置を調整するものである。
【０００５】
【発明が解決しようとする課題】
しかしながら、前記公報に提示されている従来のラッチ用受座はスライド部材を前後方向へ移動させる移動プレートがスライド部材の裏面に配置されていることから、移動プレートがスライド部材によって遮蔽されている。そのため、調整時に調整範囲が分かりにくく、どの程度操作凸部を回せば適切な位置に移動するのか確認できない、という問題点があった。
【０００６】
【課題を解決するための手段】
前記課題を解決するため、本発明のラッチ受座は、外函の底壁と内函の底壁との間に一方の内側縁にラックを形成した斜め方向に延びる長孔を備えた固定板が該外函に固定されて設けられ、前記長孔内にラックに噛み合うピニオンが配置され、且つ前記ピニオンの中心に突設させた操作突起が前記内函の底壁に形成した縦方向に延びる長孔に摺動可能に嵌挿させられ、前記操作突起を回すことによって操作突起と前記ピニオンとからなる調整部材が内函の長孔に沿って上下動しながら内函が横方向へ移動することを特徴とする。
【０００７】
前記の構成に加えて、前記内函の底壁に長孔に沿って目盛りを付した場合が好ましい。
【０００８】
【発明の実施の形態】
次に、本発明の実施の形態を図面を参照して説明する。
【０００９】
図１乃至図６は本発明の好ましい実施の形態の一つを示すものであり、ラッチ用受座１は、主に出入口枠の縦枠２に形成された堀込穴３に埋設固定される横断面凹形状の外函４と、この外函４の内部に横方向へ摺動可能に嵌装配置された横断面凹形状の内函５と、外函４の内部の底壁６に沿って固定される固定板７と、前記固定板７に形成された斜め方向へ延びる長孔２１における一方の内側縁に形成したラック２２に噛み合うピニヨン８およびその中心に突設されて前記内函の底壁に形成された縦方向へ延びる長孔に摺動可能に嵌挿される操作突起９とからなる調整部材１０と、透孔１１が形成され外函４の表面を覆うカバープレート１２とから構成される。
【００１０】
そして、外函４は表面を開口させた矩形の函形で上下端縁に縦枠２に固定される舌片１３，１３がそれぞれ折曲形成されているともに、これら舌片１３，１３に固定ねじ１４，１４が挿通される挿通孔１５，１５が形成されている。
【００１１】
また、内函５は表面を開口させた矩形の函形で両側端縁に外函４の表面の開口部を塞ぐ舌片１６，１６がそれぞれ折曲形成されているともに、底壁１７の中央に縦に延びる長孔１８が穿設されている。そして、横幅が外函４よりも短く形成されて外函４の内部に横方向へ摺動可能に嵌装配置されるもので、表面の開口はラッチが挿入される受穴１９となり、一方の縦方向へ延びる内側面がラッチが係止される係止面２０となる。
【００１２】
尚、底壁１７の表面には長孔１８に沿って内函５の移動量に対応して、例えばミリ単位の目盛り２３が付されている。
【００１３】
更に、固定板７は外函４の底壁６の内径と等しい矩形の板であり、斜め方向へ延びる長孔２１が穿設されているとともに、この長孔２１の一方の内側縁にはラック２２が形成されている。
【００１４】
調整部材１０は、ピニヨン８の中心に表面にドライバ等の工具を差し込む係止溝２４が形成されている円柱状の操作突起９が突設されている。
【００１５】
調整部材１０を形成するピニオン８は、固定板７の長孔２１に嵌挿してラック２２と噛合しているとともに、操作突起９は内函５の長孔１８に上下方向へ摺動可能に嵌挿されている。
【００１６】
従って、固定板７が外函４に固定されて固定板７の長孔２１が不動であることから、調整部材１０は、操作突起９を回すことによってピニヨン８がラック２２上を噛み合いながら回転して、内函５の長孔１８内を上下動すると同時に内函５が横方向へ摺動するのである。
【００１７】
また、カバープレート１２は、内函５の受穴１９と対応してラッチが挿通する透孔１１が穿設されているとともに、上下端には外函４の挿通孔１５，１５と対応する位置に挿通孔２５，２５が形成されている。また、透孔１１には内函５の一側縁に突設された位置決め用のガイド凸部２６に嵌合するガイド凹部２７が穿設されている。
【００１８】
以上のように構成した本実施の形態は、内函５を内装した外函４を縦枠２の堀込穴３に埋設し、カバープレート１２をその凹部２７と内函５の凸部２６に嵌合させて位置を決め、固定ねじ１４，１４をカバープレート１２の挿通孔２５，２５から外函４の挿通孔１５，１５に通して縦枠２にねじ込んで図２に示すように縦枠２に取り付けるのである。
【００１９】
そして、内函５の係止面２０とラッチの係止位置を適切に合わせるには、調整部材１０の操作突起９の係止溝２４にドライバ（図示せず）を差し込んで回転させ、内函５の横方向の位置を適切に調整するのである。
【００２０】
例えば、図３で示される調整部材１０を左に回すと図４に示すように調整部材１０が上方へ移動するとともに内函５、即ち係止面２０を図示左方向へ移動する。
【００２１】
また、図３で示される調整部材１０を右に回すと図５に示すように調整部材１０が下方へ移動するとともに内函５、即ち係止面２０を図示右方向へ移動する。
【００２２】
このとき、調整部材１０を回すにあたって、内函５に付した目盛り２３によってどの程度内函５と係止面２０を移動させたか、或いは移動可能か、など調整の範囲が正確に分かるものであり、換言すれば、調整部材１０を何ミリ移動させれば適切な位置に調整できるかが分かるものである。
【００２３】
尚、本実施の形態では、内函５の長孔１８に沿って目盛り２３を付して、ミリ単位の調整ができるように構成したが、本発明は目盛り２３を設けない構成であってもよいものである。
【００２４】
尚、目盛り２３を付さない場合は、調整部材１０が内函５の長孔１８内のどの位置にあり、どの位置に移動させるかによって、調整の範囲と調整距離などを判別すればよい。
【００２５】
【発明の効果】
以上のように本発明は、ラッチの係止面の位置を調整可能なラッチ用受座にあって、横方向の調整をラックとピニヨンとの噛合によって行わせたものであるから、確実にして安定した調整が行われるばかりか、調整後も正確な係止面を確実に維持して、使用頻度の多いラッチであっても、長期間に亙って正確な係止面を安定よく維持するものである。
【００２６】
殊に本発明は、固定板のラックを形成した斜め方向の長孔と、内函における底壁の縦方向の長孔とに調整部材を配置し、調整部材の操作突起を回すと、調整部材が上下動する同時に、内函が横方向に摺動するように構成したものであるから、調整部材の上下位置で調整範囲が判然とし、どの程度回して上下動させれば適切な調整が行えるかがはっきりするという効果がある。
【００２７】
尚、内函の長孔に沿って目盛りを付した構成にあっては、目盛りを頼りに調整部材を回して移動させることで正確な移動が行え、内函の係止面の位置調整が容易且つ正確に行えるという効果を発揮するものである。

The
[0010]
The outer box 4 is a rectangular box having an open surface, and tongue pieces 13 and 13 fixed to the vertical frame 2 are bent at the upper and lower end edges, respectively, and are fixed to the tongue pieces 13 and 13. Insertion holes 15 and 15 through which the screws 14 and 14 are inserted are formed.
[0011]
The inner box 5 is a rectangular box having an open surface, tongue pieces 16 and 16 for closing the opening on the surface of the outer box 4 are bent at both side edges, and the center of the bottom wall 17 is formed. A long hole 18 extending in the vertical direction is formed. The lateral width is shorter than that of the outer box 4 and is slidably fitted in the outer box 4 so that the opening on the surface serves as a receiving hole 19 into which the latch is inserted. The inner side surface extending in the vertical direction is a locking surface 20 on which the latch is locked.
[0012]
The surface of the bottom wall 17 is provided with a scale 23 in units of millimeters, for example, corresponding to the amount of movement of the inner box 5 along the long hole 18.
[0013]
Further, the fixed plate 7 is a rectangular plate having an inner diameter equal to the inner diameter of the bottom wall 6 of the outer box 4, and a long hole 21 extending in an oblique direction is formed, and a rack is formed on one inner edge of the long hole 21. 22 is formed.
[0014]
The adjustment member 10 has a cylindrical operation projection 9 protruding from the center of the pinion 8 in which a locking groove 24 for inserting a tool such as a screwdriver is formed on the surface.
[0015]
The pinion 8 forming the adjusting member 10 is fitted into the long hole 21 of the fixing plate 7 and meshed with the rack 22, and the operation projection 9 is fitted into the long hole 18 of the inner box 5 so as to be slidable in the vertical direction. It is inserted.
[0016]
Accordingly, since the fixing plate 7 is fixed to the outer casing 4 and the long hole 21 of the fixing plate 7 does not move, the adjusting member 10 rotates while the pinion 8 is engaged with the rack 22 by turning the operation projection 9. As a result, the inner box 5 slides in the horizontal direction at the same time as it moves up and down in the long hole 18 of the inner box 5.
[0017]
Further, the cover plate 12 has a through hole 11 through which the latch is inserted corresponding to the receiving hole 19 of the inner box 5, and positions corresponding to the insertion holes 15, 15 of the outer box 4 at the upper and lower ends. Insertion holes 25 and 25 are formed in the. Further, a guide recess 27 is formed in the through hole 11 so as to be fitted to a positioning guide protrusion 26 protruding from one side edge of the inner box 5.
[0018]
In the present embodiment configured as described above, the outer box 4 having the inner box 5 is embedded in the recessed hole 3 of the vertical frame 2, and the cover plate 12 is fitted into the concave part 27 and the convex part 26 of the inner box 5. Then, the fixing screws 14 and 14 are passed from the insertion holes 25 and 25 of the cover plate 12 through the insertion holes 15 and 15 of the outer box 4 and screwed into the vertical frame 2 as shown in FIG. It is attached to.
[0019]
