Abstract

La présente invention concerne un drain et une structure de camouflage de drain et un procédé d'installation et d'utilisation. Le mode de réalisation préféré de l'invention comprend un corps de drain conçu pour être raccordé à un bac de douche ou une baignoire étanche préfabriqué classique. Le corps de drain peut être raccordé au bac de douche par un moyen approprié quelconque, comme, par exemple, mais sans limitation, en étant moulé d'un seul tenant avec ledit bac durant la fabrication du bac, par un raccord en post-fabrication ou sur place. D'autres modes de réalisation ne nécessitent pas l'utilisation d'un bac de douche ou d'une baignoire étanche préfabriqué. Le corps de drain préféré se compose d'une structure étanche qui comporte une section de fond qui définit une ouverture de drain, et une section de paroi latérale périphérique. Une structure pour fixer un couvercle de drain au corps de drain de façon amovible est utilisée. Le couvercle, qui est défini par un bord périphérique, est conçu pour être en correspondance avec, et ainsi couvrir, une partie du fond de corps de drain afin de camoufler l'ouverture de drain et une partie aussi importante du fond de corps de drain que ce qui est pratique. Lorsqu'il est raccordé au corps de drain, le bord périphérique du couvercle est espacé de la paroi latérale de corps de drain afin d'y définir un espace à travers lequel de l'eau peut passer lorsqu'elle s'écoule vers l'ouverture de drain. De cette manière, de l'eau peut sortir de la douche ou de la baignoire sans que l'ouverture de drain soit visible. L'appareil à drain selon la présente invention est de préférence utilisé en tant que partie d'un agencement douche ou baignoire qui peut être carrelé, un matériau de plancher, tel que du carrelage, pouvant être placé sur le bac de douche ou la baignoire jusqu'à la paroi latérale périphérique du corps de drain, et un revêtement de sol supplémentaire pouvant être placé sur le couvercle de drain. De cette manière, le drain est complètement opérationnel mais n'est pas visible. Des couvercles de drain interchangeables peuvent être fournis pour permettre la modification de l'apparence décoratrice du drain.
