中框８´、横材１２´は、パネルの強度を確保するために設けるものであるが、パネルの強度を決定する要素には、その他に、パネル表面材の形状、パネル表面材の板厚、パネル表面材の見込寸法（パネルの厚さ）等の様々な要素があり、これらの要素を適宜選択して組み合わせることで所望の強度を備えたパネルを製作している。特許文献１、２にもパネルに強度を付与するための工夫が開示されている。 The intermediate rod 8 'and the cross member 12' are provided to ensure the strength of the panel. Other factors that determine the strength of the panel include the shape of the panel surface material and the thickness of the panel surface material. There are various elements such as the expected dimensions (panel thickness) of the panel surface material, and a panel having a desired strength is manufactured by appropriately selecting and combining these elements. Patent Documents 1 and 2 also disclose a device for imparting strength to the panel.

パネルの強度を向上させるにあたっては、製作コストの削減やパネル重量の軽量化等の理由から、パネル表面材の板厚やパネルの厚さを増加させるのではなく、より少ない材料、より少ない部品点数で所望の強度が確保できることが望ましい。
特開２００１−３１１３７０ 特開２００５−２２６２５０ In order to improve the strength of the panel, instead of increasing the panel surface material thickness and panel thickness for reasons such as reducing manufacturing costs and reducing the panel weight, there are fewer materials and fewer parts. It is desirable that the desired strength can be secured.

１つの態様では、本発明は、上記補強構造を備えた上側パネルと下側パネルの連結構造であって、

本発明では、中框の上下端に上側係合溝、下側係合溝を設け、パネル表面材に形成した上側係合部、下側係合部がそれぞれ、中框の上側係合溝、下側係合溝に係合するようにしたので、扉体に風圧等が作用した場合に、パネル面に対する垂直方向の力を中框が良好に負担することで、パネル表面材の変形を可及的に防止し、パネルの有効断面形状を効果的に確保し、耐風圧強度の向上を図ることができる。
特に、係合状態において、上側係合部、下側係合部がそれぞれ複数箇所で上側係合溝、下側係合溝に当接するようにして、力点を多く確保することで、中框による負荷力の向上を図ることができる。 In the present invention, an upper engagement groove and a lower engagement groove are provided at the upper and lower ends of the middle collar, and the upper engagement section and the lower engagement section formed on the panel surface material are respectively the upper engagement groove of the middle collar, Because it engages with the lower engagement groove, the panel surface material can be deformed when the wind pressure or the like acts on the door body, so that the vertical load on the panel surface can be borne well. As a result, the effective cross-sectional shape of the panel can be effectively secured, and the wind pressure strength can be improved.
In particular, in the engaged state, the upper engaging portion and the lower engaging portion are in contact with the upper engaging groove and the lower engaging groove at a plurality of locations, respectively, so as to secure a large number of power points, The load force can be improved.

パネル表面材と中框の連結に特徴を持たせてパネル強度を向上させることによって、従来と同じパネル強度を備えたパネルであっても、他の要素の設計自由度を大きくすることができる。具体的には、中框の板厚を現行の板厚より薄くしても、現行のパネルと同等以上の強度を確保することができる。また、パネル強度を落とすことなく、パネルの全体を厚さ（見込寸法）を小さくすることができる。また、パネルの幅寸法（長さ寸法）によっては、パネル強度を落とすことなく、補強用の横材を無くすことができ、あるいは部分的に横材を設けるだけでよい。また、パネル強度を向上させることによって、従来のパネルでは設置できなかった大開口に設置し得るパネルを提供することができ、従来のパネルに比べて使用範囲を広げることができる。   By improving the panel strength by giving a characteristic to the connection between the panel surface material and the intermediate wall, the design freedom of other elements can be increased even for a panel having the same panel strength as the conventional one. Specifically, even if the thickness of the middle wall is made thinner than the current plate thickness, the strength equal to or higher than that of the current panel can be secured. Further, the thickness (expected dimension) of the entire panel can be reduced without reducing the panel strength. Further, depending on the width dimension (length dimension) of the panel, the reinforcing cross member can be eliminated without reducing the panel strength, or the cross member need only be provided partially. Further, by improving the panel strength, it is possible to provide a panel that can be installed in a large opening that cannot be installed with a conventional panel, and it is possible to widen the range of use compared to a conventional panel.

本発明では、パネル表面材の変形を可及的に防止することで、鉛直方向に対する強度も向上し、繰り返される扉体の開閉に対するパネルの耐久性が向上する。
さらに、扉体が複数枚のパネルを丁番を介して連結して構成されている場合に、上記補強構造を備えた上側パネルと下側パネルの連結構造において、上側垂直辺に形成された上側係合部、下側垂直辺に形成された下側係合部が、上側係合溝、下側係合溝に係合しているので、この係合部位によって上側垂直辺、下側垂直辺に作用する力に対抗することができ、パネル表面材の変形を防止して、パネルの強度を向上させ、また、パネルの変形に伴って丁番に作用するであろう無理な力を軽減できるので、丁番の摩耗を低減することができる。 In the present invention, by preventing the deformation of the panel surface material as much as possible, the strength in the vertical direction is also improved, and the durability of the panel against repeated opening and closing of the door body is improved.
Further, when the door body is configured by connecting a plurality of panels via hinges, the upper side formed on the upper vertical side in the connection structure of the upper panel and the lower panel provided with the reinforcing structure. Since the lower engagement portion formed on the engagement portion and the lower vertical side is engaged with the upper engagement groove and the lower engagement groove, the upper vertical side and the lower vertical side are determined depending on the engagement portion. Can counteract the force acting on the panel, prevent deformation of the panel surface material, improve the strength of the panel, and reduce the unreasonable force that would act on the hinge accompanying the deformation of the panel Therefore, the wear of the hinge can be reduced.
