Description

この発明は、建屋の出入口を開閉する玄関ドアに関する。   The present invention relates to an entrance door that opens and closes an entrance of a building.

近年、古くなったマンション等の集合住宅においては、玄関ドアを含めて内装を改修する工事が行われることが非常に多くなってきている。このような改修工事が行われる集合住宅の玄関ドアにおいては、室内側に膨出する補強部を外周部に有し、その補強部で囲まれた内側部分に郵便投入口と、その郵便投入口から投入される郵便物を受け取る郵便受箱が設けられた薄板鋼板により形成されたものが多くを占めている。   In recent years, in an apartment house such as an old condominium, construction work for refurbishing the interior including a front door has been very frequently performed. In the entrance door of an apartment house where such renovation work is performed, the outer peripheral part has a reinforcing part that bulges indoors, and a mail inlet and its mail inlet in the inner part surrounded by the reinforcing part Most of them are made of sheet steel plates provided with mailboxes for receiving postal items.

上記のような薄板鋼板からなる玄関ドアにおいては、遮音性、断熱性、気密性がいずれも劣り、内装のみの改修工事では快適な居住性を得ることができない。そのような問題は、玄関ドアを新しいものと交換することによって解決することができるが、玄関ドアと共にドア枠も新しいものと交換する必要があるため、コストが高くなり、改修工事に多くの時間を必要とする不都合が生じる。   The entrance door made of a thin steel plate as described above is inferior in sound insulation, heat insulation, and airtightness, and a comfortable habitability cannot be obtained by renovation work only for the interior. Such problems can be solved by replacing the front door with a new one, but the door frame must be replaced with a new one along with the front door, which increases costs and requires a lot of time for renovation work. Inconvenience is required.

上記の不都合を解消するため、特許文献１では、ドア本体に形成された膨出状の補強部にベースパネルをねじ止めし、そのベースパネルの室内側にベースパネルを覆うカバー部材を設け、そのカバー部材とベースパネルとで形成される内パネルの内部空間内にグラスウールからなる断熱部材を収容し、上記カバー部材の外周に形成されたシール溝内にシール部材を組み込んで、ドア枠との間をシールするようにした玄関ドアを提案している。   In order to eliminate the above inconvenience, in Patent Document 1, a base panel is screwed to a bulging reinforcing portion formed on a door body, and a cover member that covers the base panel is provided on the indoor side of the base panel. A heat insulating member made of glass wool is accommodated in the internal space of the inner panel formed by the cover member and the base panel, and the seal member is incorporated in a seal groove formed on the outer periphery of the cover member, and between the door frame We have proposed a front door that seals the door.

特開２０１０−２０３０７１号公報JP 2010-203071 A

ところで、上記特許文献１に記載された玄関ドアにおいては、ドア本体の室内側に郵便受箱としての郵便受け部を設けるようにしているため、内パネルには、その郵便受け部を挿入可能とする極めて大きな切欠部を形成する必要がある。   By the way, in the entrance door described in the said patent document 1, since the mail receiving part as a mail box is provided in the indoor side of the door main body, the mail receiving part can be inserted in the inner panel. It is necessary to form a large notch.

このとき、切欠部の内周と郵便受け部の外周間に隙間が形成されて気密性が低下し、また、室内からの見栄えも悪くなるため、目隠し部材の取り付けにより隙間を閉塞する必要が生じ、改修工事に非常に手間がかかるという問題がある。   At this time, a gap is formed between the inner periphery of the notch portion and the outer periphery of the mail receiving portion, the airtightness is lowered, and the appearance from the room is also deteriorated, so it is necessary to close the gap by attaching a blindfold member, There is a problem that the renovation work is very time-consuming.

また、厚さや形状の異なる内パネルがドア本体に取り付けられた際には、内パネルの室内側の面の位置が変化して、切欠部に挿入された郵便受け部の室内側への突出量が一定とならず、郵便受箱としての郵便受け部に体裁のよい取付け状態を得ることができない。   Also, when an inner panel with a different thickness or shape is attached to the door body, the position of the inner surface of the inner panel changes, and the amount of protrusion of the mail receiving part inserted into the notch into the indoor side changes. It is not constant, and it is not possible to obtain a good state of attachment in the mail receiving portion as a mail receiving box.

この発明の課題は、隙間を閉塞する目隠し部材の取り付けを不要として改修工事の容易化を図り、厚さや形状が異なる内パネルに変更されたとしても郵便物を受け取る郵便受箱の取付けに常に体裁のよい取付け状態が得られるようにした玄関ドアを提供することである。   The object of the present invention is to eliminate the need for attaching a blindfold member that closes the gap and facilitates the renovation work. It is to provide a front door that can get a good installation condition.

上記の課題を解決するため、この発明においては、薄板鋼板で形成され、室内側に膨出する補強部を外周部に有し、その補強部で囲まれた内側の領域に郵便投入口が形成されたドア本体と、そのドア本体の室内側面に対向配置された断熱性および遮音性を有する断熱ボードを保持し、外周部が前記補強部にねじ止めされた内パネルとからなり、前記郵便投入口から差し込まれた郵便物を開閉可能な蓋体を有する郵便受箱で受け取るようにした玄関ドアにおいて、前記内パネルおよび断熱ボードのそれぞれに前記郵便投入口に対向して切欠部を形成し、その切欠部にガイド筒を組み込み、そのガイド筒を内パネルに後端部が固定される固定ガイド筒部と、その固定ガイド筒部内にスライド自在に嵌合されて先端開口部が前記郵便投入口に対向する可動ガイド筒部とで形成して伸縮調整可能とし、前記可動ガイド筒部の先端開口部内に前記郵便投入口を開閉する揺動可能な内蓋を設け、前記内パネルの室内側面に前記切欠部の室内側開口の全体を覆うようにして郵便受箱を設けた構成を採用したのである。   In order to solve the above problems, in the present invention, the outer peripheral portion has a reinforcing portion that is formed of a thin steel plate and bulges indoors, and a mail insertion port is formed in an inner region surrounded by the reinforcing portion. The post body is composed of a door body and an inner panel having a heat insulating and sound insulating board disposed opposite to the indoor side surface of the door body and having an outer peripheral portion screwed to the reinforcing portion. In the entrance door that receives the mail inserted from the mouth by a mail box having a lid that can be opened and closed, each of the inner panel and the heat insulating board forms a notch facing the mail input port, A guide cylinder is incorporated in the notch, the guide cylinder is fixed to the inner panel at the rear end, and the fixed guide cylinder is slidably fitted in the fixed guide cylinder, and the front opening is the mail input port. Opposite The movable guide cylinder part is formed to be adjustable in expansion and contraction, and a swingable inner lid for opening and closing the mail insertion port is provided in a front end opening of the movable guide cylinder part, and the cutout part is provided on the indoor side surface of the inner panel. The structure in which the mailbox was provided so as to cover the entire indoor opening of the room was adopted.

上記のように、内パネルに形成された切欠部に伸縮調整可能なガイド筒を組み込むことによって、ドア本体に厚さや形状が異なる如何なる内パネルが取り付けられたとしても、郵便受箱を内パネルの室内側面に取付け可能とすることができ、郵便受箱の取付けに常に体裁のよい取付け状態を得ることができる。   As described above, by incorporating a guide cylinder that can be expanded and contracted into the notch formed in the inner panel, the mail box is attached to the inner panel regardless of the thickness or shape of the inner panel attached to the door body. It can be attached to the side surface of the room, and it is possible to always obtain a good mounting state for mounting the mailbox.

また、内パネルの室内側面に郵便受箱を設けることにより、その郵便受箱で切欠部の室内側開口の全体を覆うことができる。このため、切欠部の内周とガイド筒の外周間に形成される隙間を目隠し部材の取り付けによって閉塞する必要がなくなり、改修工事の容易化を図ることができる。   In addition, by providing a mail box on the indoor side surface of the inner panel, it is possible to cover the entire indoor opening of the notch with the mail box. For this reason, it is not necessary to close the gap formed between the inner periphery of the notch and the outer periphery of the guide tube by attaching the blindfold member, and the repair work can be facilitated.

ここで、郵便投入口の周囲に環状の弾性シールを設け、内蓋を弾性部材により閉鎖方向に向けて付勢することにより、内蓋は閉鎖状態で弾性シールに弾性接触することになるため、郵便投入口と内蓋の対向部間の気密性を向上させることができる。   Here, since an annular elastic seal is provided around the mail insertion slot and the inner lid is biased toward the closing direction by the elastic member, the inner lid is in elastic contact with the elastic seal in the closed state. It is possible to improve the airtightness between the mail inlet and the facing part of the inner lid.

また、内蓋が郵便投入口を閉鎖する可動ガイド筒部のスライド調整位置で、その可動ガイド筒部を固定する固定手段を設けることにより、玄関ドアの開閉時に生じる振動等によってガイド筒が収縮するのを防止することができ、郵便投入口と内蓋の対向部間の気密性の維持に効果を挙げることができる。   In addition, by providing a fixing means for fixing the movable guide cylinder part at the slide adjustment position of the movable guide cylinder part where the inner lid closes the mail insertion slot, the guide cylinder contracts due to vibration or the like generated when the front door is opened and closed. Can be prevented, and an effect can be obtained in maintaining airtightness between the mail inlet and the facing portion of the inner lid.

固定手段として、可動ガイド筒部に、その可動ガイド筒部のスライド方向に長く延びる長孔を設け、その長孔に挿入されて固定ガイド筒部にねじ込まれた固定ねじの締め付けによって可動ガイド筒部を固定する構成のものを採用することができる。   As a fixing means, the movable guide cylinder is provided with a long hole extending in the sliding direction of the movable guide cylinder, and the movable guide cylinder is inserted into the long hole and screwed into the fixed guide cylinder. The thing of the structure which fixes can be employ | adopted.

この発明においては、上記のように、伸縮調整可能なガイド筒をドア本体に形成された郵便投入口と対向するようにして、そのドア本体と内パネル間に設けるようにしたので、内パネルの室内側面に郵便受箱を設けることができる。そして、その郵便受箱で切欠部の室内側の開口全体を覆うようにしたので、切欠部の内周とガイド筒の外周間に形成される隙間を目隠し部材の取り付けによって閉塞する必要がなくなり、改修工事の容易化を図ることができる。   In the present invention, as described above, the guide cylinder that can be adjusted to extend and contract is provided so as to face the mail insertion port formed in the door body, and is provided between the door body and the inner panel. A mailbox can be provided on the side of the room. And since it was made to cover the entire indoor opening of the notch with the mailbox, it is not necessary to close the gap formed between the inner periphery of the notch and the outer periphery of the guide tube by attaching a blindfold member, The repair work can be facilitated.

また、内パネルの室内側面に郵便受箱を設けることによって、郵便受箱の全体が室内側に臨む体裁のよい取付け状態を得ることができる。   In addition, by providing the mailbox on the indoor side surface of the inner panel, it is possible to obtain a good attachment state in which the entire mailbox is facing the indoor side.

For this reason, it is not necessary to close the gap formed between the inner periphery of the notch 39 and the outer periphery of the guide tube 40 by attaching a blindfold member, and the repair work can be facilitated.

ここで、内蓋４５が郵便投入口２３を閉鎖する可動ガイド筒部４２のスライド調整位置で、ねじ６２の締め付けにより可動ガイド筒部４２を固定することにより、玄関ドア２０の開閉時に生じる振動等によってガイド筒４０が収縮するのを防止することができ、郵便投入口２３と内蓋４５の対向部間の気密性の維持に効果を挙げることができる。   Here, at the slide adjustment position of the movable guide cylinder part 42 where the inner lid 45 closes the mail insertion slot 23, the movable guide cylinder part 42 is fixed by tightening the screws 62, thereby causing vibrations or the like generated when the front door 20 is opened and closed. As a result, the guide tube 40 can be prevented from contracting, and the effect of maintaining the airtightness between the opposite portions of the mail insertion slot 23 and the inner lid 45 can be obtained.
