Description

本発明は、建物の開口部を開閉する揺動型ドア装置に関し、特に、建物の開口部周縁の既存ドア枠に支持されている既存ドアを新規ドアに取り換えて開閉するようにしたものに関する。   The present invention relates to an oscillating door device that opens and closes an opening of a building, and more particularly, to an existing door that is supported by an existing door frame at the periphery of the opening of a building by replacing it with a new door.

一般に、建物の開口部を開閉する揺動型のドア装置は、吊元端部（戸尻端部）がドア枠に上下の丁番によって揺動可能に支持されたドアを備え、このドアの揺動によって開口部を開閉するようになっている。また、ドアの戸先端部には操作ハンドルによって出没するラッチが、またドア枠の縦枠にはラッチを受けるラッチ受けがそれぞれ設けられていて、両者の係合によりドアを閉じ状態に保持するようにしている。   In general, a swing-type door device that opens and closes an opening of a building includes a door whose suspension base end (door bottom end) is swingably supported on a door frame by upper and lower hinges. The opening is opened and closed by swinging. In addition, a latch that protrudes and retracts by an operation handle is provided at the door front end portion of the door, and a latch receiver that receives the latch is provided in the vertical frame of the door frame, respectively, so that the door is held in a closed state by the engagement of both. I have to.

このドア装置は、通常、ドア枠及びドアが開口部両側の柱（構造軸材）の間に位置するインセット納まりであり、ドア枠やドアの大きさは開口部の幅や高さに応じて決定される。そのため、このドア装置をリフォームするときには、既存の開口部に合わせた大きさのドア枠と扉を予め用意し、ドア枠等の交換のために開口部周囲の壁の工事が必要となり、大掛かりな工事となる。   This door device is usually an inset housing in which the door frame and the door are positioned between the pillars (structure shafts) on both sides of the opening, and the size of the door frame and the door depends on the width and height of the opening. Determined. For this reason, when remodeling this door device, a door frame and door of a size matching the existing opening are prepared in advance, and the construction of the wall around the opening is necessary to replace the door frame and the like. It will be construction.

一方、このようなインセット納まりのドア装置とは異なり、アウトセット納まりと呼ばれるドア装置が知られている。このアウトセット納まりのドア装置は、例えは特許文献１に示されるように、ドア枠及びドアが開口部の一側に配置され、そのドアの吊元端部がドア枠の一側面に丁番を介して揺動可能に支持されており、ドアの閉じ状態では開口部全体を一側から覆うように閉じるものである。   On the other hand, a door device called outset storage is known, unlike such an inset storage door device. In this outset-contained door device, as shown in Patent Document 1, for example, the door frame and the door are arranged on one side of the opening, and the hanging end of the door is hinged on one side of the door frame. The door is closed so as to cover the entire opening from one side when the door is closed.

実開平６−６２１８１号公報Japanese Utility Model Publication No. 6-62181

そこで、上記インセット納まりのドア装置をリフォームするときに、特許文献１に示されるように、既存のドアに変わる新しいドアを開口部の一側に配置してアウトセット納まりの構造に変更すれば、ドア枠やドアの開口部に対する制約がなくなり、壁の工事等の大掛かりな工事が不要となるので都合が良い。   Therefore, when remodeling the door device with the inset, as shown in Patent Document 1, if a new door that replaces the existing door is arranged on one side of the opening and changed to a structure with an outset. This is convenient because there are no restrictions on the door frame and the opening of the door, and a large-scale construction such as a wall construction is unnecessary.

ところが、その場合、上記特許文献１のもののように、新しいドアを支持する丁番をドア枠の一側面に取り付けようとしても、例えば、そのドア枠がＭＤＦで形成されていたり、面取りや切り欠き等があったり、或いは木口にモールが形成されていたりすると、丁番を安定して取り付けることが難しくなり、丁番の取付位置も制限されるという問題が生じる。   However, in that case, even if a hinge supporting a new door is attached to one side of the door frame as in the above-mentioned Patent Document 1, for example, the door frame is formed of MDF, chamfered or notched. If there is such a thing or if a molding is formed at the end, it becomes difficult to stably attach the hinge, and there arises a problem that the attachment position of the hinge is also limited.

本発明は斯かる点に鑑みてなされたもので、その目的は、インセット納まりのドア装置をアウトセット納まりの構造にリフォームする際に、ドアを支持する丁番の取付構造に改良を加えることにより、丁番を安定して取り付けるとともに、丁番の取付位置の制限も不要にしようとすることにある。   The present invention has been made in view of such a point, and an object of the present invention is to improve a hinge mounting structure for supporting a door when an inset door device is reformed to an outset housing structure. Thus, the hinge is stably attached and the restriction of the attachment position of the hinge is made unnecessary.

上記の目的を達成するために、この発明では、新しいドアの丁番を既存のドア枠に取り付けるのではなく、開口部周縁の柱等の構造軸材に取付固定するようにした。   In order to achieve the above object, according to the present invention, a new door hinge is not attached to an existing door frame, but is attached and fixed to a structural shaft such as a column at the periphery of the opening.

具体的には、第１の発明は、建物の開口部を、該開口部周縁の既存ドア枠又は開口部周縁の端部に支持されている既存ドアに代わる新規ドアにより開閉するようにした揺動型ドア装置であって、上記新規ドアは、開口部の前側に配置されかつ吊元端部（戸尻端部）が上記開口部周縁部に丁番を介して揺動可能に支持されていて、閉じ状態では開口部全体を該開口部の前側から覆うように閉じるものとされ、上記丁番は、開口部近傍の柱等の構造軸材に対し、開口部周縁部の前側壁から構造軸材に到達する長さのビスにより取り付けられていることを特徴とする。   Specifically, in the first invention, the opening of the building is opened and closed by a new door that replaces the existing door frame at the periphery of the opening or the existing door supported at the end of the periphery of the opening. In the movable door device, the new door is arranged on the front side of the opening, and a suspension end (door end) is swingably supported on the peripheral edge of the opening via a hinge. In the closed state, the entire opening is closed so as to cover from the front side of the opening, and the hinge is structured from the front side wall of the opening peripheral portion with respect to the structural shaft such as a column near the opening. It is characterized by being attached by a screw having a length reaching the shaft member.

この第１の発明では、新規ドアは開口部の前側に配置されており、その吊元端部が建物の開口部周縁部に丁番を介して揺動可能に支持され、閉じ状態では新規ドアが開口部全体をその前側から覆うように閉じるアウトセット納まりであるので、新規ドアは開口部の幅や高さよりも大きくしさえすれば、それらの制約を受けることがない。   In the first aspect of the invention, the new door is arranged on the front side of the opening, and its hanging end is supported swingably on the peripheral edge of the opening of the building via a hinge. Is an outset that closes the entire opening from its front side, so that the new door is not subject to these restrictions as long as it is larger than the width and height of the opening.

しかも、新規ドアは開口部の前側から開口部全体を覆うように閉じるので、既存のドアを取り除いて、新規ドアを取り付けるだけで新たなドア装置が得られることとなり、開口部周囲の壁の工事等の大掛かりな工事が不要となり、建物の躯体の下地工事を要することなくドア装置を施工することができ、リフォームの工期が短くなり、その費用も少なくて済む。   Moreover, since the new door is closed from the front side of the opening so as to cover the entire opening, a new door device can be obtained simply by removing the existing door and installing the new door. Such a large-scale construction is not necessary, and the door device can be constructed without requiring the foundation work of the building frame, the renovation work period is shortened, and the cost can be reduced.

また、新規ドアが閉じ状態では開口部全体をその前側から覆うので、前側から見て新規ドアが開口部周縁の壁等から浮き出るようになり、新規ドアにより既存ドア枠又は開口部周縁の端部が隠蔽されてすっきりした美麗な納まりが得られる。   In addition, since the entire opening is covered from the front side when the new door is closed, the new door is lifted off from the wall or the like around the opening when viewed from the front, and the edge of the existing door frame or the periphery of the opening by the new door. Is concealed and a clean and beautiful fit is obtained.

また、新規ドアの吊元端部を支持する丁番が開口部周縁の構造軸材に届くビスにより取付固定されているので、丁番が既存ドア枠に影響されることなく安定して構造軸材に取り付けられ、新規ドアの支持構造が強固となり、そのドアの安定した開閉動作を長期間に亘って維持することができ、その信頼性を高めることができる。しかも、丁番は構造軸材に取付固定されればよいので、丁番はビスで固定される構造軸材の幅で取付位置が調整可能であるだけでなく、安定して取付可能である。   In addition, since the hinge that supports the hanging end of the new door is fixed by screws that reach the structural shaft around the opening, the structural shaft can be stably moved without being affected by the existing door frame. It is attached to the material, the support structure of the new door is strengthened, the stable opening / closing operation of the door can be maintained over a long period of time, and its reliability can be improved. Moreover, since the hinge only needs to be attached and fixed to the structural shaft, the hinge can be attached not only with the width of the structural shaft fixed with screws, but also stably.

そして、本発明の特徴として、図２に示すように、上記上部丁番１０及び下部丁番の各々における固定部材１１，１５は、その取付部１１ａ，１５ａにおいて、開口部Ｏ近傍で既存ドア枠５の右縦枠５ａよりも外側（右側）に位置する右柱１（構造軸材）に対し、開口部Ｏの前側である前側空間Ｓ１から、各ビス挿通孔１７に挿通されプラスターボード２を貫通して右柱１に到達する長さの複数のビスＶ，Ｖ，…（ねじ釘）により取り付けられている。尚、このビスＶは、説明の都合のために簡略的に示しており、以下の各実施形態での説明も同様である。また、図２中、１８は開口部Ｏ近傍の右柱１（構造軸材）前側において上下の丁番１０，１４間に配置される縦枠で、プラスターボード２を介して右柱１に固定されている。   As a feature of the present invention, as shown in FIG. 2, the fixing members 11 and 15 in each of the upper hinge 10 and the lower hinge are attached to the existing door frame in the vicinity of the opening O in the attachment portions 11a and 15a. 5 is inserted into each screw insertion hole 17 through the plaster board 2 from the front space S1 which is the front side of the opening O with respect to the right column 1 (structural shaft material) located outside (right side) of the right vertical frame 5a. And a plurality of screws V, V,... (Screw nails) having a length reaching the right column 1. Note that this screw V is simply shown for convenience of explanation, and the explanation in each of the following embodiments is also the same. In FIG. 2, reference numeral 18 denotes a vertical frame disposed between the upper and lower hinges 10 and 14 on the front side of the right column 1 (structure shaft member) near the opening O, and is fixed to the right column 1 via the plaster board 2. ing.

一方、新規ドア８の戸先端部側の内部にはその上下の略中央部にラッチ機構（全体は図示せず）が取り付けられている。このラッチ機構は公知構造のものであり、新規ドア８の前後面に突出するボックス部１９と、このボックス部１９に揺動可能に支持され、新規ドア８を前後方向に貫通する操作軸２０とを有し、この操作軸２０の前後両端部にはそれぞれ操作ハンドル２１，２１が回動一体に取付固定されている。また、ラッチ機構は、後側に突出するボックス部１９の左側面に対し出没可能に支持されかつ操作軸２０に連動機構（図示せず）を介して駆動連結されたラッチ２３を有し、このラッチ２３の先端部の後側（後側空間Ｓ２側）には、左方向に向かうに従って前側（前側空間Ｓ１側）に向かうように傾斜する傾斜面２３ａが形成されている。ラッチ２３は、ボックス１９内のバネ等により突出方向に付勢されて常時は戸先端部の木口面から突出しており、操作ハンドル２１を回し操作して操作軸２０を回動させたとき、又はラッチ２３が没入方向に押されたときに、ラッチ２３が突出付勢力に抗してボックス１９内に没入するようになっている。   On the other hand, a latch mechanism (the whole is not shown) is attached to the inside of the new door 8 on the door front end side at a substantially central portion thereof. This latch mechanism has a known structure, and includes a box portion 19 projecting from the front and rear surfaces of the new door 8, and an operation shaft 20 that is swingably supported by the box portion 19 and penetrates the new door 8 in the front-rear direction. The operation handles 21 and 21 are attached to and fixed to the front and rear ends of the operation shaft 20 in an integral manner. Further, the latch mechanism includes a latch 23 that is supported so as to be able to protrude and retract with respect to the left side surface of the box portion 19 protruding rearward and is drivingly connected to the operation shaft 20 via an interlocking mechanism (not shown). On the rear side (rear side space S2 side) of the front end of the latch 23, an inclined surface 23a is formed so as to be inclined toward the front side (front side space S1 side) as it goes leftward. The latch 23 is urged in the protruding direction by a spring or the like in the box 19 and normally protrudes from the wooden face of the door tip, and when the operation handle 21 is turned to rotate the operation shaft 20, or When the latch 23 is pushed in the immersion direction, the latch 23 is immersed in the box 19 against the protruding biasing force.

また、上記既存ドア枠５において戸先側の左縦枠５ａの前面には戸当たり用縦枠２５がビス（図示せず）により固定されている。このビスは、戸当たり用縦枠２５及び既存ドア枠５の左縦枠５ａの各前端部を貫通して左柱１に届くように後側に向かって左側に向かうように斜めに止めることが好ましい。   In the existing door frame 5, a door-holding vertical frame 25 is fixed to the front surface of the door-side left vertical frame 5 a with screws (not shown). The screws can be diagonally stopped so as to go to the left side toward the rear so as to reach the left pillar 1 through the front end portions of the vertical frame 25 for door contact and the left vertical frame 5a of the existing door frame 5. preferable.

戸当たり用縦枠２５の右側面には、その上下の略中央部に、上記新規ドア８の戸先側のラッチ２３に係合可能な凹陥部からなるラッチ受け２６が形成されている。そして、新規ドア８が開き状態から上下の丁番１０，１４回りに図２で時計回り方向に回動して閉じたときに、新規ドア８の戸先側のラッチ２３における傾斜面２３ａがラッチ受け２６前側の側壁部に押されてラッチ２３が突出付勢力に抗してドア８内に没入し、そのラッチ２３がラッチ受け２６前側の側壁部を超えた後に突出付勢力により突出してラッチ受け２６内に嵌入し該ラッチ受け２６と係合することで、新規ドア８はその戸先端部の後面が戸当たり用縦枠２５の前面に当接して閉じ状態にロック保持される一方、操作ハンドル２１を操作してラッチ２３を没入させることで、ラッチ２３とラッチ受け２６との係合が解除されて、ドア８を前側に移動させて開き操作し得るようになっている。   On the right side surface of the vertical frame 25 for door contact, a latch receiver 26 formed of a recessed portion that can be engaged with the latch 23 on the door-end side of the new door 8 is formed in the upper and lower central portions. Then, when the new door 8 is turned from the opened state to the upper and lower hinges 10 and 14 in the clockwise direction in FIG. 2 and closed, the inclined surface 23a of the latch 23 on the door side of the new door 8 is latched. The latch 23 is pushed by the side wall portion on the front side of the receiver 26 and enters into the door 8 against the protruding biasing force, and the latch 23 protrudes by the protruding biasing force after exceeding the side wall portion on the front side of the latch receiver 26. 26, the new door 8 is locked in a closed state with the rear surface of the door front end abutting against the front surface of the door contact vertical frame 25. By operating 21 and immersing the latch 23, the engagement between the latch 23 and the latch receiver 26 is released, and the door 8 can be moved forward and opened.

したがって、上記実施形態では、建物の開口部Ｏに施工されている既存のドア装置を新規のドア装置Ａに交換してリフォームする場合、既存のドア装置の既存ドア枠５はそのまま残してドアのみをその丁番ごと取り外し、その後に新規のドア装置Ａを施工すればよい。具体的には、新規ドア８の吊元端部にピボット丁番からなる上下丁番１０，１４の回動部材１２，１６を取り付け、それら上下丁番１０，１４の固定部材１１，１５を開口部Ｏ周りの吊元側部に位置する右柱１に対しプラスターボード２上からビスＶにより固定することで、新規ドア８を丁番１０，１４によって揺動可能に支持する。一方、既存ドア枠５の左縦枠５ａ前面に戸当たり用縦枠２５を取付固定し、その縦枠２５に、新規ドア８に内蔵されているラッチ機構のラッチ２３が係合可能なラッチ受け２６を形成すればよい。   Therefore, in the above embodiment, when an existing door device installed in the opening O of the building is replaced with a new door device A and reformed, the existing door frame 5 of the existing door device is left as it is and only the door is left. Can be removed together with the hinge, and then a new door device A can be installed. Specifically, rotating members 12 and 16 of upper and lower hinges 10 and 14 comprising pivot hinges are attached to the hanging end of the new door 8, and the fixing members 11 and 15 of the upper and lower hinges 10 and 14 are opened. The new door 8 is swingably supported by hinges 10 and 14 by being fixed with screws V from the top of the plaster board 2 to the right column 1 located on the hanging side portion around the portion O. On the other hand, a door-holding vertical frame 25 is attached and fixed to the front surface of the left vertical frame 5a of the existing door frame 5, and a latch receiver to which a latch 23 of a latch mechanism built in the new door 8 can be engaged. 26 may be formed.

そのとき、新規ドア８は開口部Ｏの前側に配置されたアウトセット納まりであり、その吊元端部（右端部）が建物の開口部Ｏ周縁部に上下の丁番１０，１４を介して揺動可能に支持され、閉じ状態では新規ドア８が開口部Ｏ全体をその前側から覆うように閉じる。このため、新規ドア８は開口部Ｏの幅や高さよりも大きくしさえすれば、それらの制約を受けることがない。しかも、新規ドア８は開口部Ｏの前側から開口部Ｏ全体を覆うように閉じるので、既存のドアを取り除いて、新規ドア８を取り付けるだけで新たなドア装置Ａにリフォームされることとなり、既存ドア枠５等の交換は不要で、その交換のために開口部Ｏ周囲の壁の工事等の大掛かりな工事をしなくて済む。すなわち、建物の躯体の下地工事を要することなく既存ドア枠５を活かしてドア装置Ａを施工することができるので、リフォームの工期が短くなり、その費用も少なくなる。   At that time, the new door 8 is an outset housing arranged on the front side of the opening O, and its suspension end (right end) is connected to the peripheral edge of the opening O of the building via upper and lower hinges 10 and 14. In a closed state, the new door 8 is closed so as to cover the entire opening O from the front side. For this reason, as long as the new door 8 is made larger than the width and height of the opening O, these restrictions are not imposed. Moreover, since the new door 8 is closed from the front side of the opening O so as to cover the entire opening O, the existing door is removed and the new door 8 is simply attached to the new door device A. There is no need to replace the door frame 5 or the like, and a large-scale work such as a wall work around the opening O is not necessary for the replacement. That is, since the door apparatus A can be constructed by utilizing the existing door frame 5 without requiring the foundation work of the building frame, the renovation work period is shortened and the cost thereof is reduced.

また、新規ドア８は閉じ状態で開口部Ｏ全体をその前側から覆うので、前側から見て新規ドア８が開口部Ｏ周縁の壁部等から浮き出るように見えるようになり、新規ドア８により既存ドア枠５が隠蔽されてすっきりした美麗な納まりが得られる。   In addition, since the new door 8 covers the entire opening O from the front side in the closed state, the new door 8 can be seen to emerge from the wall of the periphery of the opening O as viewed from the front side. The door frame 5 is concealed and a clean and beautiful fit is obtained.

また、新規ドア８の吊元端部を支持する上下丁番１０，１４の固定部材１１，１５が開口部Ｏ周縁の右柱１（構造軸材）に届くビスＶにより取付固定されているので、それらの丁番１０，１４は既存ドア枠５に影響されることなく安定して右柱１に取り付けられ、新規ドア８の支持構造は強固となる。そのため、ドア８の安定した開閉動作を長期間に亘って維持することができ、その信頼性を高めることができる。しかも、丁番１０，１４は右柱１にビスＶによって直接的に取付固定されるので、その取付位置が既存ドア枠５等により制限されることはない。   In addition, the fixing members 11 and 15 of the upper and lower hinges 10 and 14 that support the hanging end of the new door 8 are fixed by screws V that reach the right column 1 (structure shaft member) at the periphery of the opening O. These hinges 10 and 14 are stably attached to the right column 1 without being affected by the existing door frame 5, and the support structure of the new door 8 becomes strong. Therefore, the stable opening / closing operation | movement of the door 8 can be maintained over a long period of time, and the reliability can be improved. In addition, since the hinges 10 and 14 are directly attached and fixed to the right column 1 with the screws V, their attachment positions are not limited by the existing door frame 5 or the like.

また、開口部Ｏの戸先側周縁部に位置する既存ドア枠５の左縦枠５ａ前側に戸当たり用縦枠２５が取り付けられ、その縦枠２５に新規ドア８の戸先側のラッチ２３に係合するラッチ受け２６が設けられているので、新規ドア８を閉じ状態に保持するためのラッチ受け２６を容易に設けることができる。   Also, a door-holding vertical frame 25 is attached to the front side of the left vertical frame 5a of the existing door frame 5 located at the door-edge-side peripheral portion of the opening O, and the door-side latch 23 of the new door 8 is attached to the vertical frame 25. Therefore, the latch receiver 26 for holding the new door 8 in the closed state can be easily provided.

さらに、この実施形態の場合、ラッチ機構のラッチ２３が新規ドア８の戸先側木口面においてではなく、その後面に突出するボックス部１９において出没するように設けられているので、そのラッチ機構のボックス部１９やラッチ２３を新規ドア８の外に配置した分だけ新規ドア８の厚さを薄くすることができる。尚、ボックス部１９は新規ドア８の後面ではなくて前面に突出するようにして、その前面の左側面に対しラッチ２３を出没させるようにしてもよい。   Furthermore, in the case of this embodiment, the latch 23 of the latch mechanism is provided so as to protrude and retract at the box portion 19 protruding from the rear face rather than at the door end side of the new door 8. The thickness of the new door 8 can be reduced by the amount that the box portion 19 and the latch 23 are disposed outside the new door 8. Note that the box portion 19 may protrude to the front surface instead of the rear surface of the new door 8, and the latch 23 may be protruded and retracted with respect to the left side surface of the front surface.

（実施形態２）
図５は本発明の実施形態２を示し（尚、以下の各実施形態では、図１〜図４と同じ部分については同じ符号を付してその詳細な説明は省略する）、閉じ状態にある新規ドア８と既存ドア枠５との間に隙間が生じないようにしたものである。 (Embodiment 2)
FIG. 5 shows a second embodiment of the present invention (in the following embodiments, the same parts as those in FIGS. 1 to 4 are denoted by the same reference numerals and detailed description thereof is omitted) and are in a closed state. A gap is not generated between the new door 8 and the existing door frame 5.

すなわち、この実施形態では、実施形態１とは異なり、ラッチ２３は、新規ドア８の戸先端部の木口面に対し出没可能に支持されている。また、既存ドア枠５の左縦枠５ａの前面に戸当たり用縦枠２５が固定されておらず、その既存ドア枠５よりも外側（左側）に位置する左柱１に対し前側から縦枠２７がプラスターボード２を貫通するビス（図示せず）により固定され、この縦枠２７の右側面にラッチ受け２６が形成されている。   That is, in this embodiment, unlike the first embodiment, the latch 23 is supported so as to be able to appear and retract with respect to the end face of the door tip of the new door 8. Further, the vertical door frame 25 is not fixed to the front surface of the left vertical frame 5 a of the existing door frame 5, and the vertical frame from the front side with respect to the left pillar 1 positioned outside (left side) of the existing door frame 5. 27 is fixed by screws (not shown) penetrating the plaster board 2, and a latch receiver 26 is formed on the right side surface of the vertical frame 27.

また、既存ドア枠５の左右の縦枠５ａ，５ａ及び横枠の各前面にはモヘアシールやゴムバッキン等からなる隙間埋め部材２８が一体的に取付固定されており、新規ドア８が閉じ状態にあるときに、その新規ドア８と既存ドア枠５との間の隙間を隙間埋め部材２８によって閉塞するようにしている。その他の構成は実施形態１と同様である。   Further, a gap filling member 28 made of mohair seal, rubber backing, or the like is integrally attached and fixed to the front surfaces of the left and right vertical frames 5a and 5a and the horizontal frame of the existing door frame 5, so that the new door 8 is in a closed state. In some cases, the gap between the new door 8 and the existing door frame 5 is closed by the gap filling member 28. Other configurations are the same as those of the first embodiment.

したがって、この実施形態でも実施形態１と同様の作用効果が得られる。また、この実施形態の場合、閉じ状態にある新規ドア８と既存ドア枠５との間の隙間が隙間埋め部材２８によって閉塞されるので、新規ドア８を閉じたときに既存ドア枠５との間に隙間が生じることがなく、ドア装置Ａの密閉感や外観見映えを高めることができる。   Therefore, this embodiment can provide the same effects as those of the first embodiment. Further, in the case of this embodiment, the gap between the new door 8 in the closed state and the existing door frame 5 is closed by the gap filling member 28, so that when the new door 8 is closed, There is no gap between them, and the sealing feeling and appearance of the door device A can be enhanced.

（実施形態３）

図７は実施形態４を示し、既存ドア枠５を隠蔽する隠しカバー３１にラッチ受け２６を設けたものである。 (Embodiment 4)
FIG. 7 shows a fourth embodiment in which a latch receiver 26 is provided on a hidden cover 31 that hides the existing door frame 5.

すなわち、この実施形態では、既存ドア枠５は実施形態１〜３のものとは異なっていてそれよりも薄肉で小さい幅の板材からなり、その幅（前後方向の寸法）は開口部Ｏ周りの壁部の厚さ（柱１の前後幅に前後のプラスターボード２，２の厚さを加えた寸法）と同じで、幅方向の両端部である前後端部は壁部（プラスターボード２，２）の表面と面一となっている。   That is, in this embodiment, the existing door frame 5 is different from those in the first to third embodiments, and is made of a plate material that is thinner and smaller in width, and its width (dimension in the front-rear direction) is around the opening O. It is the same as the wall thickness (the dimension obtained by adding the thickness of the front and rear plaster boards 2 and 2 to the front and rear width of the pillar 1), and the front and rear end portions that are both ends in the width direction are the wall portions (plaster boards 2 and 2) It is flush with the surface.

隠しカバー３１の前側分割カバー部材３２は、縦枠５ａないし横枠において、前面全体と、内面のうちの前半部とを覆うように断面略Ｌ字状の板材からなり、既存ドア枠５外側のプラスターボード２の端部をも部分的に覆うようになっている。一方、後側分割カバー部材３３は、前側分割カバー部材３２と同様に、縦枠５ａないし横枠において、後面全体と、内面のうちの後半部とを覆うように断面略Ｌ字状の板材からなり、既存ドア枠５外側のプラスターボード２の端部をも部分的に覆うようになっている。   The front divided cover member 32 of the hidden cover 31 is made of a plate material having a substantially L-shaped cross section so as to cover the entire front surface and the front half of the inner surface of the vertical frame 5a to the horizontal frame. The end portion of the plaster board 2 is also partially covered. On the other hand, as with the front divided cover member 32, the rear divided cover member 33 is made of a plate material having a substantially L-shaped cross section so as to cover the entire rear surface and the rear half of the inner surface in the vertical frame 5a or the horizontal frame. Thus, the end portion of the plaster board 2 outside the existing door frame 5 is also partially covered.

そして、前側分割カバー部材３２のうち、戸先側の左縦枠５ａを覆っている上下方向に延びる前部は他の部分よりも厚肉で、実施形態１の戸当たり用縦枠２５と同等の厚さとされ、その厚肉部分の右側面にラッチ受け２６が形成されている。その他の構成は実施形態１と同様である。   And among the front side division | segmentation cover members 32, the front part extended in the up-down direction which covers the left vertical frame 5a by the side of a door is thicker than another part, and is equivalent to the vertical frame 25 for door stop of Embodiment 1.
