Description

本発明は建物間を接続する部分の壁面間の開口部を覆ったり、開口部となる地面にレールを備えた門扉等として使用される目地装置に関する。   The present invention relates to a joint device used as a gate door or the like that covers an opening between wall surfaces of a portion that connects buildings, or that has a rail on the ground serving as an opening.

従来、レールを使用して開閉扉や目地プレートを移動させる目地装置は、開閉扉や目地プレートが常時位置していない部位のレールは開放状態となっているため、ゴミ等が溜まり、開閉扉や目地プレートの動作不良となったり、美観を損なったり、不衛生になるという欠点があった。   Conventionally, joint devices that use rails to move the doors and joint plates are open because the rails of the parts where the doors and joint plates are not always located are open. There were drawbacks in that the joint plate malfunctioned, the aesthetic appearance was impaired, and it became unsanitary.

特許第4729510号公報Japanese Patent No. 4729510

本発明は以上のような従来の欠点に鑑み、レールに案内されて移動する開口部を覆う門扉や、目地プレートが常時位置していないレール部位の上部を覆って、ゴミ等が溜まるのを効率よく阻止して、動作不良が生じるのを阻止し、美観の向上および不衛生になるのを効率よく阻止することができる目地装置を提供することを目的としている。   In view of the above-described conventional drawbacks, the present invention efficiently covers the gate that covers the opening that moves while being guided by the rail, and the upper part of the rail portion where the joint plate is not always positioned, so that dust and the like can be efficiently collected. An object of the present invention is to provide a joint device that can prevent well and prevent malfunction, and can efficiently prevent aesthetic improvement and poor hygiene.

本発明の前記ならびにそのほかの目的と新規な特徴は次の説明を添付図面と照らし合わせて読むと、より完全に明らかになるであろう。
ただし、図面はもっぱら解説のためのものであって、本発明の技術的範囲を限定するものではない。
The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in conjunction with the accompanying drawings.
However, the drawings are for explanation only and do not limit the technical scope of the present invention.

上記目的を達成するために、本発明は開口部となる部位の地面、開口部が形成された床面あるいは天井面のいずれかに、上部あるいは下部が開口するように取付けられたハット形鋼あるいはチャンネル状のレールと、このレールに案内されて移動する目地プレートとからなる目地装置において、前記目地プレートが常時位置していない部位の前記レール部位の上部位置に取付けられた、該目地プレートが移動してくると両側部方向へ押し圧されて開口する、常時閉鎖方向に付勢する付勢機構を備えた一対の開閉扉本体を有する開閉扉と、この開閉扉と対応する部位の前記目地プレートに設けられた、前記一対の開閉扉本体間に侵入して開放する山形形状の突起とを備えて目地装置を構成している。   In order to achieve the above object, the present invention provides a hat-shaped steel attached so that the upper part or the lower part is opened on the ground, the floor surface on which the opening is formed, or the ceiling surface. In a joint device composed of a channel-shaped rail and a joint plate that moves while being guided by the rail, the joint plate attached to the upper position of the rail portion where the joint plate is not always located is moved. An opening / closing door having a pair of opening / closing door bodies provided with an urging mechanism for urging in a normally closing direction that is pressed and opened in the direction of both sides when coming, and the joint plate corresponding to the opening / closing door And a chevron-shaped protrusion that enters and opens between the pair of opening / closing door main bodies to constitute a joint device.

以上の説明から明らかなように、本発明にあっては次に列挙する効果が得られる。
(1)請求項1により、目地プレートが位置していない部位のレールを常時閉鎖方向に付勢する付勢機構を備えた一対の開閉扉で、閉じた状態にすることができる。
したがって、一対の開閉扉で閉じられたレール内にゴミが侵入するのを確実に阻止でき、美観の向上と、不衛生になるのを防止することができる。
(2)前記(1)により、目地プレートが移動する場合には、目地プレートの端部に設けた山形形状の突起で一対の開閉扉を開放して移動するため、比較的スムーズに移動できるとともに、一対の開閉扉で目地プレートを押し圧するように作用するため、目地プレートの移動方向と直角方向に揺れ動くのを効率よく阻止することができる。
(3)前記(1)により、ハット形鋼形状あるいはチャンネル状のレールに付勢機構を備える一対の開閉扉と、目地プレートに山形形状の突起を設けるだけでよいので、比較的簡単に設置することができるとともに、既存のレールにも簡単に設置することができる。
(4)請求項2も前記(1)〜(3)と同様な効果が得られるとともに、確実にレールの上部を常時閉鎖した状態にすることができる。
As is clear from the above description, the present invention has the following effects.
(1) According to the first aspect, the pair of doors including a biasing mechanism that constantly biases the rail of the portion where the joint plate is not positioned in the closing direction can be closed.
Therefore, it is possible to reliably prevent dust from entering the rails closed by the pair of opening / closing doors, and to improve aesthetics and prevent unsanitary conditions.
(2) According to the above (1), when the joint plate moves, the pair of opening and closing doors are moved by the chevron-shaped projections provided at the end of the joint plate, so that the joint plate can move relatively smoothly. Since the joint plate acts to press the joint plate with the pair of opening and closing doors, it is possible to efficiently prevent the joint plate from swinging in the direction perpendicular to the moving direction of the joint plate.
(3) According to the above (1), it is only necessary to provide a pair of opening / closing doors provided with a biasing mechanism on a hat-shaped steel or channel-shaped rail, and a mountain-shaped projection on the joint plate, so that it is installed relatively easily And can be easily installed on existing rails.
(4) According to the second aspect, the same effects as in the above (1) to (3) can be obtained, and the upper portion of the rail can be reliably closed at all times.
