従来、先端に傾斜面が形成されているラッチボルトをラッチ本体に出没可能に設け、ラッチ本体を扉側に、ラッチ受け部材を躯体側に設置し、扉が閉まる際に、ラッチボルトが傾斜面からラッチ受け部材の表面にのるようにして没し、ラッチ受け部材の受孔内にラッチボルトが突出して、扉の閉状態を保持するラッチ錠が知られている。   Conventionally, a latch bolt with an inclined surface formed at the tip is provided in the latch body so that it can protrude and retract. The latch body is installed on the door side and the latch receiving member is installed on the housing side. There is known a latch lock which is sunk on the surface of the latch receiving member from above and a latch bolt projects into the receiving hole of the latch receiving member to keep the door closed.

また、通常のラッチ錠は、左開きの扉又は右開きの扉の何れかに対応するものであるが、特許文献１では、左開きの扉と右開きの扉の何れにも対応することができるラッチ錠が提案されている。特許文献１のラッチ錠は、ラッチボルトの先端の厚さ方向中央に略矩形の垂直板を設け、その両側面を当接面とし、当接面の上下方向中央に略４分の１円状の水平板を設け、その外側に傾斜する摺接面を設け、厚さ方向及び上下方向を対称に構成すると共に、ラッチ受け部材の略中央に略矩形の受孔を設け、ラッチボルトの進入側の縁に水平板が収容される収容部を受孔に連続して設け、受孔と収容部で正面視略Ｔ字形となるようにし、収容部の上下に垂直板の当接面が当接する当受部を設けるものである。   In addition, a normal latch lock corresponds to either a left-open door or a right-open door, but in Patent Document 1, it can correspond to either a left-open door or a right-open door. Possible latch locks have been proposed. The latch lock of Patent Document 1 is provided with a substantially rectangular vertical plate at the center in the thickness direction of the tip of the latch bolt, with both side surfaces as contact surfaces, and approximately a quarter circle in the vertical center of the contact surface. The horizontal plate is provided, a sliding contact surface is provided on the outer side thereof, the thickness direction and the vertical direction are configured symmetrically, a substantially rectangular receiving hole is provided in the approximate center of the latch receiving member, and the latch bolt entry side A receiving portion for receiving the horizontal plate is provided at the edge of the receiving portion so as to be continuous with the receiving hole so that the receiving hole and the receiving portion are substantially T-shaped in front view, and the contact surfaces of the vertical plates are in contact with the upper and lower sides of the receiving portion. This receiving part is provided.

ところで、扉には前方又は後方の何れか一方に開閉するもの以外に、前方と後方の両方に開閉する扉もあり、斯様な両開きの扉に使用できるラッチ錠も望まれる。しかしながら、通常のラッチ錠や特許文献１のラッチ錠は、扉が戸当たりに当たって停止する際に、この停止状態を利用してラッチボルトがラッチ受け部材の受孔に突出し、扉の閉状態を保持するものであるため、これらのラッチ錠を戸当たりがない両開きの扉に用いた場合には、扉が閉状態を通り過ぎて逆方向に開状態となってしまうという問題が生ずる。そのため、前後何れからの閉動作においても、両開きの扉の閉状態を確実に保持することができる両開き扉用のラッチ錠が求められる。   By the way, in addition to doors that open and close either forward or backward, there are doors that open and close both forward and backward, and latch locks that can be used for such double-open doors are also desired. However, in the case of a normal latch lock or a latch lock disclosed in Patent Document 1, when the door stops when it comes into contact with the door, the latch bolt projects into the receiving hole of the latch receiving member using this stop state, and the door is kept closed. Therefore, when these latch locks are used for a double door that does not have a door stop, there arises a problem that the door passes through the closed state and opens in the opposite direction. Therefore, there is a need for a double door latch lock that can reliably maintain the closed state of the double door regardless of whether the door is closed from the front or the rear.

本発明は上記課題に鑑み提案するものであって、戸当たりがない両開きの扉に用いることが可能であり、前後何れからの閉動作においても、両開きの扉の閉状態を確実に保持することができる両開き扉用ラッチ錠及び両開き扉構造を提供することを目的とする。   The present invention is proposed in view of the above-described problems, and can be used for a double-open door that does not have a door stop, and reliably holds the closed state of the double-open door in any of the front and rear closing operations.

〔第１実施形態の両開き扉用ラッチ錠〕
本発明による第１実施形態の両開き扉用ラッチ錠を図面を参照して説明する。図１（ａ）は第１実施形態の両開き扉用ラッチ錠のラッチ本体を示す正面図、（ｂ）はそのラッチ本体の平面図、（ｃ）はそのラッチ本体の側面図。図２（ａ）は第１実施形態の両開き扉用ラッチ錠のラッチ受け部材を示す正面図、（ｂ）はそのラッチ受け部材の側面図である。 [Latch lock for double doors of the first embodiment]
A double door latch lock according to a first embodiment of the present invention will be described with reference to the drawings. FIG. 1A is a front view showing a latch body of the double door latch lock of the first embodiment, FIG. 1B is a plan view of the latch body, and FIG. 1C is a side view of the latch body. Fig.2 (a) is a front view which shows the latch receiving member of the latch lock for double doors of 1st Embodiment, (b) is a side view of the latch receiving member.

第１実施形態の両開き扉用ラッチ錠は、図１及び図２に示すように、ラッチボルト１１を出没可能に設けられるラッチ本体１０と、ラッチボルト１１の受孔２１を有するラッチ受け部材２０とから構成される。   As shown in FIGS. 1 and 2, the latch lock for double doors of the first embodiment includes a latch body 10 that is provided so that the latch bolt 11 can be retracted and a latch receiving member 20 having a receiving hole 21 for the latch bolt 11. Consists of

ラッチ本体１０は、図１に示すように、ラッチボルト１１が収容されるケース１４を有し、ケース１４の前端には鍔状のプレート１５が形成されている。プレート１５の前面にはフロントプレート１６が重ねられ、螺子止めで固定されており、フロントプレート１６の孔１７からラッチボルト１１が出没するようになっている。ラッチボルト１１を出没させるケース１４内の構造は、バネでラッチボルト１１を前方に付勢する構成など、適宜の公知技術を適用することが可能である。   As shown in FIG. 1, the latch body 10 has a case 14 in which the latch bolt 11 is accommodated, and a bowl-shaped plate 15 is formed at the front end of the case 14. A front plate 16 is overlapped on the front surface of the plate 15 and is fixed by screwing. The latch bolt 11 protrudes from a hole 17 of the front plate 16. As a structure in the case 14 in which the latch bolt 11 is projected and retracted, an appropriate known technique such as a configuration in which the latch bolt 11 is urged forward by a spring can be applied.

ラッチボルト１１の先端部には、その略中央に略矩形の垂直板１２が設けられており、垂直板１２は両開き扉用ラッチ錠を両開き扉に設置した際の扉回動の軸方向に延びて形成されている。また、ラッチボルト１１の先端部には、垂直板１２と直交する水平板１３が設けられており、水平板１３はその略中央に垂直板１２が位置するように設けられている。第１実施形態では、図１（ａ）の垂直板１２の上下端に相当する垂直板１２の両端にそれぞれ略三角形の水平板１３が形成されており、複数である２個の水平板１３が垂直方向に間隔を開けて形成されている。   A substantially rectangular vertical plate 12 is provided at the center of the front end of the latch bolt 11. The vertical plate 12 extends in the axial direction of the door rotation when the double door latch lock is installed on the double door. Is formed. In addition, a horizontal plate 13 orthogonal to the vertical plate 12 is provided at the tip of the latch bolt 11, and the horizontal plate 13 is provided so that the vertical plate 12 is positioned at the approximate center thereof. In the first embodiment, substantially triangular horizontal plates 13 are formed at both ends of the vertical plate 12 corresponding to the upper and lower ends of the vertical plate 12 in FIG. 1A, and a plurality of two horizontal plates 13 are provided. It is formed at intervals in the vertical direction.

垂直板１２の両側に位置する、後述するラッチ受け部材２０の前面と摺接可能な水平板１３の摺接面１３１は、垂直板１２の先端に向かって窄まる傾斜面になっている。本実施形態における傾斜面である摺接面１３１の傾斜角度は、垂直板１２に対して２５°〜６０°程度とすると好適である。尚、摺接面１３１を、平面状の傾斜面にする構成に代え、垂直板１２の先端に向かって窄まる外側に凸の弧状曲面とすることも可能である。   The slidable contact surfaces 131 of the horizontal plate 13 that can be slidably contacted with the front surface of a latch receiving member 20 described later, which are located on both sides of the vertical plate 12, are inclined surfaces that narrow toward the tip of the vertical plate 12. The inclination angle of the sliding contact surface 131 which is an inclined surface in the present embodiment is preferably about 25 ° to 60 ° with respect to the vertical plate 12. It should be noted that the sliding contact surface 131 may be an arcuate curved surface projecting outward toward the front end of the vertical plate 12 instead of a flat inclined surface.

ラッチ受け部材２０は、図２に示すように、略直方体形の本体２２を有し、本体２２の前面２３のラッチボルト１１が進退する方向の両側縁には傾斜面に面取りされるようにして傾斜ガイド部２４が形成されている。前面２３の略中央には、横から見るとＨ字形である正面視Ｉ字形の受孔２１が形成されている。受孔２１の形状はラッチボルト１１の先端部の垂直板１２及び水平板１３で形成される形状と略対応し、受孔２１の大きさはラッチボルト１１の先端部の大きさよりも若干大きくなっており、突出するラッチボルト１１の先端部が受孔２１に略嵌合可能になっている。垂直板１２が略嵌合する位置に対応する、ラッチ受け部材２０の摺接面である前面２３と受孔２１の内面とが突き合う角部２５は、横断面視略直角となっている。   As shown in FIG. 2, the latch receiving member 20 has a substantially rectangular parallelepiped main body 22, and the both sides of the front surface 23 of the main body 22 in the direction in which the latch bolt 11 advances and retreats are chamfered by inclined surfaces. An inclined guide portion 24 is formed. A receiving hole 21 having an I-shape in front view, which is H-shaped when viewed from the side, is formed in the approximate center of the front surface 23. The shape of the receiving hole 21 substantially corresponds to the shape formed by the vertical plate 12 and the horizontal plate 13 at the tip of the latch bolt 11, and the size of the receiving hole 21 is slightly larger than the size of the tip of the latch bolt 11. Thus, the protruding tip end portion of the latch bolt 11 can be substantially fitted into the receiving hole 21. A corner portion 25 corresponding to a position where the vertical plate 12 is substantially fitted and where the front surface 23 which is a sliding contact surface of the latch receiving member 20 and the inner surface of the receiving hole 21 abuts is substantially perpendicular to the cross section.

次に、第１実施形態の両開き扉用ラッチ錠を両開き扉に設置した際の動作について説明する。図３（ａ）はラッチ受け部材に一方側からラッチボルトが進入してきた状態を示す一部断面正面図、（ｂ）はその側面図、図４（ａ）はラッチ受け部材にラッチボルトの先端部が嵌まり込んだ状態を示す一部断面正面図、（ｂ）はその側面図、図５（ａ）はラッチ受け部材から他方側にラッチボルトが退出する状態を示す一部断面正面図、（ｂ）はその側面図である。   Next, the operation when the double door latch lock of the first embodiment is installed on the double door will be described. 3A is a partially sectional front view showing a state in which the latch bolt has entered the latch receiving member from one side, FIG. 3B is a side view thereof, and FIG. 4A is the tip of the latch bolt on the latch receiving member. FIG. 5B is a side view of a part thereof, and FIG. 5A is a partly sectional front view showing a state in which the latch bolt is retracted from the latch receiving member to the other side. (B) is the side view.

両開き扉の前側から扉が閉鎖される際には、図３の矢印Ｆに示す方向にラッチボルト１１の先端部が移動し、ラッチボルト１１の水平板１３の一方側の摺接面１３１が傾斜ガイド部２４に摺接し、ラッチボルト１１の先端部がラッチ受け部材２０の前面２３上に導かれる。そして、ラッチボルト１１が前面２３で押されて引っ込み、ラッチボルト１１の先端部が前面２３上を摺動する。更に移動すると、図４に示すように、垂直板１２が受孔２１上に至り、ケース１４内の付勢機構でラッチボルト１１が突出し、垂直板１２及び水平板１３が受孔２１に挿入されて、ラッチボルト１１の先端部が受孔２１に略嵌合される。ラッチボルト１１の先端部が受孔２１に略嵌合した状態では、垂直板１２の両側面が受孔２１の両側の垂直板受部２１１・２１１に略当接し、扉の閉状態が保持される。   When the door is closed from the front side of the double door, the tip of the latch bolt 11 moves in the direction shown by the arrow F in FIG. 3, and the sliding contact surface 131 on one side of the horizontal plate 13 of the latch bolt 11 is inclined. The tip end portion of the latch bolt 11 is guided onto the front surface 23 of the latch receiving member 20 in sliding contact with the guide portion 24. Then, the latch bolt 11 is pushed and retracted at the front surface 23, and the tip of the latch bolt 11 slides on the front surface 23. When further moved, as shown in FIG. 4, the vertical plate 12 reaches the receiving hole 21, the latch bolt 11 protrudes by the urging mechanism in the case 14, and the vertical plate 12 and the horizontal plate 13 are inserted into the receiving hole 21. Thus, the tip of the latch bolt 11 is substantially fitted into the receiving hole 21. In a state where the front end portion of the latch bolt 11 is substantially fitted in the receiving hole 21, both side surfaces of the vertical plate 12 substantially abut on the vertical plate receiving portions 211 and 211 on both sides of the receiving hole 21, and the door is kept closed. The

尚、ラッチボルト１１が受孔２１に略嵌合した状態でのラッチボルト１１の最大挿入深さは３ｍｍ以上とすると、ラッチボルト１１の先端部の受孔２１に対する嵌合状態の安定性を高めることができ、より確実に扉の閉状態を保持することができて好適であり、より好ましくは、扉の開動作の容易性と嵌合状態の一層の安定性から５ｍｍ以上３０ｍｍ以下とするとよい。   In addition, when the maximum insertion depth of the latch bolt 11 in a state where the latch bolt 11 is substantially fitted in the receiving hole 21 is 3 mm or more, the stability of the fitting state of the leading end portion of the latch bolt 11 with respect to the receiving hole 21 is improved. It is preferable that the closed state of the door can be held more surely, and more preferably, it should be 5 mm or more and 30 mm or less from the ease of the door opening operation and the further stability of the fitted state. .

そして、扉を前側から後側に開ける際には図示省略するケース１４内等の解除機構によってラッチボルト１１を引っ込め、ラッチボルト１１の先端部の受孔２１に対する略嵌合を解除して、図５に示すように扉の開動作に伴ってラッチボルト１１の先端部を矢印Ｆの方向に移動する。また、両開き扉の後側から扉を閉鎖する際には、逆の動作により、図５の矢印Ｂの如くラッチボルト１１の先端部を移動させ、図６のようにラッチボルト１１の先端部を受孔２１に略嵌合し、更に後側から前側に扉を開ける際にはラッチボルト１１を引っ込め、図３の矢印Ｂに示すように扉の開動作に伴ってラッチボルト１１の先端部を矢印Ｂの方向に移動する。   When the door is opened from the front side to the rear side, the latch bolt 11 is retracted by a release mechanism in the case 14 (not shown), etc., and the engagement of the front end portion of the latch bolt 11 with the receiving hole 21 is released. As shown in FIG. 5, the tip of the latch bolt 11 is moved in the direction of arrow F along with the opening operation of the door. When closing the door from the rear side of the double door, the tip of the latch bolt 11 is moved as shown by the arrow B in FIG. 5 by the reverse operation, and the tip of the latch bolt 11 is moved as shown in FIG. When the door is opened from the rear side to the front side, the latch bolt 11 is retracted when the door is opened from the rear side to the front side. As shown by an arrow B in FIG.
