Description

本発明は、中空二重壁構造の背面壁にヒンジ部を介してそれぞれ連結された中空二重壁構造の左側面壁および右側面壁板をそれぞれヒンジ部で正面方向に折り曲げて構成する樹脂製組立構造体に関するものである。 The present invention relates to a resin assembly structure in which a left side wall and a right side wall plate of a hollow double wall structure respectively connected to a back wall of a hollow double wall structure via a hinge part are bent in the front direction at the hinge part. It is about the body.

熱可塑性樹脂から成る中空二重壁構造の複数のパネルを立体的に組み立てる組立構造体については、その具体例の洗面台キャビネットとともに特開２００１−３４０１４６号公報に記載されており、底面パネルを基体としてそれに背面パネルおよび両側面パネルをそれぞれスライド嵌合構造により取り付ける構成も例示されている。また、中空二重壁構造の左側板、背板および右側板を圧縮薄肉化したヒンジにより一連に連結してあって、ヒンジを折り曲げてキャビネットの左側板、背板および右側板の隔壁を構成することについては、特開平９−３１３２６２号公報に記載されている。 An assembly structure for three-dimensionally assembling a plurality of panels having a hollow double-wall structure made of thermoplastic resin is described in Japanese Patent Application Laid-Open No. 2001-340146 together with a wash basin cabinet of the specific example. Further, a configuration in which the rear panel and the both side panels are attached to each of them by a slide fitting structure is also illustrated. Also, the left side plate, back plate and right side plate of the hollow double wall structure are connected in series by a compression-thinned hinge, and the hinge is bent to form the partition of the left side plate, back plate and right side plate of the cabinet. This is described in JP-A-9-313262.

前掲の特許文献１に記載されている技術によれば、底面パネルを基体としてそれに背面パネルおよび両側面パネルをそれぞれスライド嵌合構造により取り付けて組み立てるので、組立工程において底面パネルに取り付けられる背面パネルおよび両側面パネルの支持状態が安定せず、組立作業に支障をきたすことが指摘されていた。そこで前掲の特許文献２に記載されている技術のように、背板に左側板および右側板をヒンジにより連結してあるものを底板に組み付けるようにすれば組立作業上の不具合をかなり改善することはできても、左側板、背板および右側板を一体とした形態が必ずしも安定しないので、依然として組立作業が容易でないのが実情である。 According to the technique described in the above-mentioned Patent Document 1, since the bottom panel is used as a base body and the back panel and the both side panels are attached to each other by a slide fitting structure, the back panel and the back panel attached to the bottom panel in the assembly process It has been pointed out that the support state of both side panels is not stable, which hinders assembly work. Therefore, as in the technique described in the above-mentioned Patent Document 2, if the left and right plates connected to the back plate by hinges are assembled to the bottom plate, problems in assembling work can be considerably improved. Even if it is possible, since the form in which the left side plate, the back plate and the right side plate are integrated is not necessarily stable, the assembly work is still not easy.

And a side wall fixing member that is fixed over the inner surface of the right side wall near the front side, so that the left side wall, the back wall, and the right side wall can be easily attached to the bottom wall as a stable integrated structure. An object of the present invention is to provide a resin assembly structure which is improved in workability and is robust and excellent in durability.
