Abstract:
A shadow mask support frame for a colour cathode ray tube, that is rectangular in shape overall and substantially parallel to the reference plane of the frame, having:two substantially rectilinear end uprights parallel to each other, each end upright comprising at least one substantially plane wall perpendicular to the reference plane of the frame and having one edge which is intended to receive a shadow mask in an arrangement substantially parallel to the reference plane of the frame, and two lateral uprights that are tubular in shape overall, each having a main part with a substantially rectilinear axis and two end parts each connected to a joining portion for joining to an end upright, the joining portion being connected in an arrangement orthogonal with respect to the reference plane of the frame and parallel to the substantially plane wall of the end upright, the lateral uprights having axes parallel to each other situated in a plane parallel to the reference plane of the frame, and the joining portion having lateral faces perpendicular to the reference plane of the frame, wherein each of the joining portions is in contact through one of its lateral faces with an internal face of the substantially plane wall perpendicular to the reference plane of the frame, so that the end uprights of the frame are in abutment on the lateral faces of the joining portions of the lateral uprights.
