Description

本発明は、トリガー、トリガーに連動する鎌片及びラッチング機構を備えた引戸錠に関する。   The present invention relates to a trigger, a sickle piece interlocking with the trigger, and a sliding door lock provided with a latching mechanism.

錠箱のフロントから受け金具に向かって突出するトリガー(水平突出杆)と、このトリガーに連動する鎌片を備えた建具用引戸錠は、例えば実開昭57−110260号公報(特許文献1)に記載されている。   For example, Japanese Utility Model Publication No. 57-110260 (Patent Document 1) discloses a sliding door lock for a joinery provided with a trigger (horizontal protrusion) projecting from the front of the lock box toward the receiving bracket and a sickle piece interlocking with the trigger. It is described in.

この種の引戸錠は、引戸の閉戸時、トリガーはその先端面がストライクの表面に突き当たると後退し始め、鎌片は動力変換機構(例えばラック及びピニオン)を介して掛合方向へと突出する。   In this type of sliding door lock, when the sliding door is closed, the trigger starts to retract when the tip end face of the strike strikes the surface of the strike, and the sickle piece protrudes in the engaging direction via a power conversion mechanism (for example, rack and pinion). .

したがって、例えば引戸を急激に閉めた時の「引戸跳ね返り現象(跳ね返り)」によって引戸が戻ると、鎌片は錠箱側に容易に後退し、トリガーは鎌片が回転した分だけ動力変換機構を介してストライク側へ進出する関係にある。   Therefore, for example, when the sliding door returns due to the “sliding door rebound phenomenon (bounce back)” when the sliding door is suddenly closed, the sickle piece easily retreats to the lock box side, and the trigger has a power conversion mechanism corresponding to the rotation of the sickle piece. Through the strike side.

そこで、引戸を閉めた時の跳ね返りを防止するために、建具用引戸錠には、普通一般にラッチング機構(仮施錠機構)が組込まれている。ラッチング機構を備えた先行技術の一つとして例えば特開2002−322850号公報(特許文献2)が存在する。この特許文献2は、本発明の外延となり得る先行技術である。   Therefore, in order to prevent rebound when the sliding door is closed, a latching mechanism (temporary locking mechanism) is generally incorporated in the sliding door lock for joinery. For example, Japanese Patent Laid-Open No. 2002-322850 (Patent Document 2) exists as one of the prior arts provided with a latching mechanism. This Patent Document 2 is a prior art that can be an extension of the present invention.

したがって、本願発明は、「引戸を閉めると、戸枠側の受け金具に当たって錠箱内に後退するトリガー、固定軸に軸支されかつトリガーの後退動に連動して前記受け金具に係合する方向へ回転する鎌片、該鎌片が受け金具に係合すると前記トリガーを自動的に係止するラッチング機構を備えた引戸錠」を前提とする。   Accordingly, the invention of the present application states that "when the sliding door is closed, a trigger that retreats into the lock box by hitting the receiving metal on the door frame side, a direction that is pivotally supported by the fixed shaft and interlocked with the retreating movement of the trigger. And a sliding door lock provided with a latching mechanism that automatically locks the trigger when the sickle piece engages with a receiving bracket.

ところで、特許文献2に記載の発明は、「引戸閉戸時の跳ね返り防止」のみならず、「鎌片やラッチング機構の破損防止」を目的としている。そのために、引戸閉戸時、ラッチング機構の新規な構成により、鎌片を錠箱の後壁側へ後退させ得る。すなわち、特許文献2に記載の発明は、「引戸閉戸時、跳ね返り現象が生じすると、ラッチング機構を構成する仮施錠用係止爪片は、ラッチ板の係合歯から受ける係合解除方向への力により、係合方向へ常時付勢する錠箱内の戻しバネのバネ力に抗して、かつ、係合解除片に形成した水平案内長孔に係合する係合ピン並びに錠箱に形成した逃し案内長孔に係合する可動枢支ピンを介して、前記水平案内長孔の遊び間隙側及び逃し案内長孔の緩衝用間隙側へと同時移行することを特徴とする。   By the way, the invention described in Patent Document 2 is aimed not only at “preventing rebound when the sliding door is closed” but also “preventing damage to sickle pieces and latching mechanisms”. Therefore, when the sliding door is closed, the sickle piece can be moved backward to the rear wall side of the lock box by a new configuration of the latching mechanism. That is, the invention described in Patent Document 2 states that “when the rebound phenomenon occurs when the sliding door is closed, the temporarily locking claw pieces constituting the latching mechanism are in the disengagement direction received from the engagement teeth of the latch plate. Against the spring force of the return spring in the lock box, which is always urged in the engagement direction, and the engagement pin that engages the horizontal guide slot formed in the disengagement piece and the lock box. Through the movable pivot pin that engages with the formed escape guide slot, the horizontal guide slot moves simultaneously to the play gap side and the escape guide slot to the buffer gap side.

上記構成の新規事項の一つとして、「鎌片の基端部側に該鎌片を錠箱の後壁側へ後退させ得る鎌片長孔を形成しているが、この鎌片長孔は、引戸閉戸時、引戸をさらに閉めることによって、鎌片を錠箱内に後退させることができるから、チリ調整機能を果たしている(特許文献2の段落0025にその旨の記載)。   As one of the new matters of the above configuration, “a sickle piece long hole is formed on the base end side of the sickle piece, and the sickle piece can be moved backward to the rear wall side of the lock box. When the door is closed, the sickle piece can be moved back into the lock box by further closing the sliding door, so that the function of adjusting the dust is described (described in paragraph 0025 of Patent Document 2).

したがって、特許文献2に記載の発明は、引戸閉戸時の跳ね返り防止、鎌片やラッチング機構の破損防止、引戸閉戸時におけるチリ調整機能等幾つかの優れた利点を有している。   Therefore, the invention described in Patent Document 2 has several excellent advantages such as prevention of rebound when the sliding door is closed, prevention of damage to the sickle piece and the latching mechanism, and a function of adjusting the dust when the sliding door is closed.

しかしながら、特許文献2に記載の発明は、錠箱の一方側の空間(例えばトリガーを基準にした下方の内部空間)に動力変換手段を介して該トリガーに連動する鎌片とラッチング機構を構成する各部材(ラッチ板、仮施錠用係止片、バネ部材、係止片等)を配設しているので、サッシ側の縦框が、狭い縦框(狭框)の場合には適用し難いという問題点があった。
実開昭57−110260号公報 特開2002−322850号公報
However, the invention described in Patent Document 2 configures a latching mechanism and a sickle piece interlocking with the trigger via power conversion means in a space on one side of the lock box (for example, a lower internal space with respect to the trigger). Since each member (latch plate, temporary locking locking piece, spring member, locking piece, etc.) is provided, it is difficult to apply when the vertical sash on the sash side is narrow (narrow). There was a problem.
Japanese Utility Model Publication No. 57-110260 JP 2002-322850 A

本発明の目的は、特許文献2の利点を備えながら、その問題点(サッシ側の縦框が狭框の場合にも容易に適用し得ること。)を解消することである。   An object of the present invention is to eliminate the problem (that can be easily applied to a case where the sash-side vertical gutter is narrow) while having the advantages of Patent Document 2.

本発明の引戸錠は、引戸を閉めると、戸枠側の受け金具に当たって錠箱内に後退するトリガー、固定軸に軸支されかつトリガーの後退動に連動して前記受け金具に係合する方向へ回転する鎌片、該鎌片が受け金具に係合すると前記トリガーを自動的に係止するラッチング機構を備えた引戸錠に於いて、前記錠箱は狭い縦框(狭框)に沿って取り付けられ得る長箱状に形成され、該長箱状の錠箱の略中央部には前記トリガーを設け、このトリガーを基準にして一方の内部空間に動力変換手段を介して該トリガーに連動する鎌片を配設し、他方の内部空間にラッチング機構を構成する各部材を配設したことを特徴とする。   In the sliding door lock of the present invention, when the sliding door is closed, the trigger is retracted into the lock box by hitting the receiving bracket on the door frame side, and is supported by the fixed shaft and engaged with the receiving bracket in conjunction with the backward movement of the trigger. In a sliding door lock provided with a latching mechanism that automatically locks the trigger when the sickle piece engages with a receiving bracket, the lock box is arranged along a narrow vertical shaft (narrow). It is formed in the shape of a long box that can be attached, and the trigger is provided at a substantially central portion of the long box-like lock box, and is linked to the trigger via power conversion means in one internal space with reference to this trigger. A sickle piece is disposed, and each member constituting the latching mechanism is disposed in the other internal space.

また、ここで「狭い縦框(狭框)」とは、建具や錠前の当業者の立場から、錠箱の入る、又は錠箱が取り付けられる当該縦框が、基準縦框と比較して「狭い」との印象を受け取ることができるものをいう。例えば基準縦框の側辺部の端面間の横幅が120mmである場合に於いて、当該縦框の横幅が、その半分の60mmである場合には、ここでいう狭框の一例に含まれるものとする。   In addition, “narrow downspread” here means from the standpoint of a person skilled in the art of fittings and locks that the downspout into which the lockbox is inserted or to which the lockbox is attached is compared with the reference downspout. A thing that can receive the impression of “narrow”. For example, when the width between the end faces of the side edges of the reference vertical wall is 120 mm, and the horizontal width of the vertical wall is half that of 60 mm, it is included in an example of the narrowness here. And

したがって、基準縦框の寸法が建具のデザイン等により変わり、例えば基準縦框100mmである場合には、当該縦框の横幅が50mm(その半分)、60mm(半分よりやや大き目)、40mm(半分よりやや小さめ)等は、当然に狭框の概念に含まれる。   Therefore, the dimensions of the standard downpile vary depending on the design of the joinery. For example, when the standard downpile is 100 mm, the horizontal width of the downpile is 50 mm (half), 60 mm (slightly larger than half), 40 mm (from half) (Slightly smaller) is naturally included in the concept of narrowness.

(1)サッシ側の縦框が狭框の場合にも容易に適用し得る。
(2)錠箱内の空間部分の有効利用を図ることができる。
(1) The present invention can be easily applied even when the vertical sash on the sash side is narrow.
(2) The space part in the lock box can be effectively used.

図1乃至図7に示す第1実施例を参照に本発明の引戸錠Xを説明する。   The sliding door lock X of the present invention will be described with reference to the first embodiment shown in FIGS.

(7)作用
図5はラッチング機構Zの仮施錠状態に至る概略説明図である。したがって、ラッチング機構Zの仮施錠状態が解消する場合は、図5とは逆の作動態様となる。また、図6は、閉戸時の一例に於いて、鎌片43、引戸1等も含めた全体の動きを示す概略説明図である。
(7) Action FIG. 5 is a schematic explanatory view of the latching mechanism Z reaching the temporarily locked state. Therefore, when the temporary locking state of the latching mechanism Z is canceled, the operation mode is the reverse of that in FIG. FIG. 6 is a schematic explanatory diagram showing the overall movement including the sickle piece 43, the sliding door 1 and the like in an example when the door is closed.

まず、図2と図6とを対比すると明らかなように、図2は引戸1を矢印A方向に閉める途中に於いて、トリガー31の先端部32がストライク4の掛合片6に当たる寸前を示しているのに対し、図6はトリガー31がトリガー支持部材15及び前記突起40に案内されて錠箱10内に後退し、該トリガー31の後退動に連動して鎌片43が固定軸23を支点に時計(掛合)方向に回転し、その結果、鎌片43の先端部43aがストライク4に係合した状態を示している。   First, as is clear from a comparison between FIG. 2 and FIG. 6, FIG. 2 shows a position just before the tip 32 of the trigger 31 hits the engaging piece 6 of the strike 4 in the middle of closing the sliding door 1 in the direction of arrow A. On the other hand, in FIG. 6, the trigger 31 is guided by the trigger support member 15 and the protrusion 40 and retracts into the lock box 10, and the sickle piece 43 supports the fixed shaft 23 as the trigger 31 moves backward. It shows that the tip 43a of the sickle piece 43 is engaged with the strike 4 as a result.

図2から図6の閉戸時状態になる過程に於いて、ラッチング機構Zを構成するラッチ板52は、トリガー31が後退動すると、当然のことながら、上方可動軸35が第2横長案内長孔25内を錠箱の後壁に向かって移動することから、固定支軸51を支点にして反時計方向へと回転する。したがって、ラッチ板52の係止爪52aは、引戸1の閉鎖位置に対応して仮施錠用係止片55の他端部に係合する。この時、仮施錠用係止片55は、バネ部材54のバネ力に抗して一旦上方に押し上げられるものの、バネ部材54の復帰力により、ラッチ板52の係止爪52aのいずれかに自動的に係合する。これが仮施錠状態である。この仮施錠状態を解消する場合には、図示しない外部の操作手段を介して係合解除片57を上方へ引くと、仮施錠用係止片55は、連係手段を介して係合解除(時計方向)に回転する。   2 to 6, when the trigger 31 is retracted, the latch plate 52 constituting the latching mechanism Z naturally moves the upper movable shaft 35 to the second lateral guide length. Since it moves in the hole 25 toward the rear wall of the lock box, it rotates counterclockwise around the fixed support shaft 51 as a fulcrum. Accordingly, the locking claw 52 a of the latch plate 52 is engaged with the other end portion of the temporary locking locking piece 55 corresponding to the closed position of the sliding door 1. At this time, although the temporary locking locking piece 55 is once pushed upward against the spring force of the spring member 54, it is automatically applied to one of the locking claws 52 a of the latch plate 52 by the restoring force of the spring member 54. Engaging. This is a temporary locking state. In order to cancel this temporary locking state, when the engagement releasing piece 57 is pulled upward via an external operation means (not shown), the temporary locking locking piece 55 is disengaged (clockwise) via the linkage means. Direction).

ところで、図7は、引戸閉戸時におけるチリ調整機能を示す説明図である。前述したように鎌片長孔44はチリ調整機能を有する。したがって、図6の所定のチリを有する閉鎖位置にて、さらに、引戸1を矢印A方向へ閉めた場合には、鎌片43は、錠箱10の第1横長案内長孔20の直線案内部20b及び鎌片43の鎌片長孔44の両者に案内される固定軸23を介してトリガー31と一緒に錠箱10内に後退する格好となる。   By the way, FIG. 7 is explanatory drawing which shows the dust adjustment function at the time of sliding door closing. As described above, the sickle piece long hole 44 has a function of adjusting dust. Therefore, when the sliding door 1 is further closed in the direction of arrow A in the closed position having the predetermined dust in FIG. 6, the sickle piece 43 is the straight guide portion of the first horizontally long guide slot 20 of the lock box 10. 20b and the sickle piece long hole 44 of the sickle piece 43 are set to retreat into the lock box 10 together with the trigger 31 via the fixed shaft 23 guided.

本実施例の長箱状錠箱10は、図6で示すように、フロント11を基準にした縦框1a内のスペースに収納され得る。また、本実施例の縦框1aのガラスやフロントを基準にした端面間の横幅は、60mmないし40mmである。   As shown in FIG. 6, the long box-shaped lock box 10 of the present embodiment can be stored in a space in the vertical hook 1 a with the front 11 as a reference. Further, the lateral width between the end faces based on the glass or front of the vertical gutter 1a of this embodiment is 60 mm to 40 mm.

また、本実施例では、受け金具Yは、ストライク4の表面から突出する掛合片6を有しているが、掛合片6は本発明の特定(限定)要件ではない。また、鎌片43の鎌片長孔44は、受け金具Y側に掛合片6を有しない場合には、鎌片が突出したままの状態で引戸1を閉めた場合においても、鎌片が錠箱10内に後退し得るように所要の長さに設定され得る。さらに、ラッチング機構Zを構成する各部材の連係手段、係合解除片57と錠箱10側の案内軸56との係合関係等は、任意に設計変更可能である。   Moreover, in this embodiment, the receiving metal fitting Y has the engaging piece 6 protruding from the surface of the strike 4, but the engaging piece 6 is not a specific (limited) requirement of the present invention. Further, when the sickle piece long hole 44 of the sickle piece 43 does not have the engaging piece 6 on the receiving metal Y side, the sickle piece is locked even when the sliding door 1 is closed with the sickle piece protruding. It can be set to the required length so that it can be retracted into 10. Further, the design of the linking means of each member constituting the latching mechanism Z, the engagement relationship between the engagement release piece 57 and the guide shaft 56 on the lock box 10 side, and the like can be arbitrarily changed.
