Chassis angle piece for use in window or door opening, has pad oriented towards base and forming angle with axis perpendicular to median plane of upper wall, such that pad is tilted towards angle of inclination of opening face

摘要

The angle piece (1C) has a front wall, a rear wall and an upper wall forming a cylindrical cover that is opened towards a base for passage of cloth. A pad oriented towards the base forms an angle (X) with an axis perpendicular to a median plane of the upper wall. The pad forms the angle such that the pad is tilted towards an angle corresponding to inclination of a face of an opening supporting the pad. An independent claim is also included for a chassis including a trunk, two slides and two angle pieces.
