A tension mask frame assembly for a color cathode-ray tube, the assembly including a tension mask and a frame, is provided. The tension mask has a plurality of strips isolated from each other at predetermined intervals on a thin plate to form slots, and tie bars for partitioning slots at a predetermined pitch interval by connecting adjacent strips to each other. The frame has a pair of support members for supporting the longer sides of the tension mask, a pair of elastic members, the ends of which are connected to both ends of each of the support members so that the support members are isolated from each other a predetermined distance, and a reinforcing member having both ends coupled to both ends of the exterior side surface of each of the support members and its center portion contacting with the exterior side surface of each of the support members, the reinforcing member for elastically restoring the support members in a direction where a tensile force is applied to the strips. In the tension mask frame assembly for a color cathode-ray tube having such a structure, deformation of the support members is reduced by the reinforcing member, so that a uniform tensile force is applied to the tension mask supported by the supporters.

Tension mask frame assembly of color cathode-ray tube

A color selection apparatus includes a frame comprising a pair of supporting members disposed in parallel with each other and a pair of elastic members disposed between and coupled to the supporting members. Each of the elastic members is formed of a hollow tube. A mask is coupled to the supporting members while being applied with a predetermined tension, and exhaust openings are formed for exhausting remaining alien substances from within the elastic members during an assembling process of the color selection apparatus. The exhaust openings are formed on each of the elastic members at a portion adjacent to where the elastic members are coupled to the supporting members.
