CA 2289111

A door frame comprises opposed door jambs and a door head, with the jambs and head each being formed from a metal section (6) of channel-shape having a base wall (8) which carries a door stop (12) and opposed side walls (10) of a width such that when the section (6) is applied to a door opening within a wall with plasterboard sheeting (16) on the wall around the opening, the opposed side walls (10) of the section (6) will overlap and lie closely adjacent to the outer surface of the plasterboard (16) with the edge of the plasterboard (16) being concealed with the interior of the section (6), the opposed side walls (10) being perforated to permit a skim coat of plaster to be applied over the side walls (10) and adjacent part of the plasterboard (16) to conceal the presence of the side walls. In one embodiment the metal section is formed from two components which engage with a friction fit to provide width-adjustment of the section to suit walls of different widths.

L'invention porte sur un cadre de porte qui comporte des montants opposés et une traverse, tous faits d'un profilé métallique (6) en forme de canal présentant une paroi de base (8) comportant une butée (12) de porte et deux parois latérales opposées (10) d'une largeur telle que lorsque le profilé (6) est posée dans une ouverture de porte pratiquée dans un mur revêtu de plaques de plâtre (16) autour de l'ouverture, les deux parois opposées (10) du profilé (6) recouvrent de très près la surface extérieure des plaques de plâtre (16), les bords des plaques de plâtre (16) étant alors dissimulés par l'intérieur du profilé (6). Les parois opposées (10) sont perforées pour permettre d'appliquer un enduit de plâtre sur les parois latérales (10) et les parties contiguës de la plaque de plâtre (16) afin de dissimuler lesdites parois latérales. Dans une variante, le profilé métallique est fait de deux parties s'assemblant par friction et permettant d'ajuster la largeur du profilé à des murs d'épaisseurs différentes.
