Abstract
A bracket is provided to couple a mask frame to a stud of a panel in a color picture tube having a tube axis. The mask frame has a rectangular rim in parallel with the tube axis and a flange vertically extending from a rear end of the rectangular rim towards the tube axis. The bracket includes a suspending arm disposed in parallel with the tube axis and provided with a hole coupled to the stud, a fixing arm fixed on the rectangular rim of the mask frame, and a vibration absorber connecting the fixing arm and the suspending arm and having a predetermined length.
Claims20
An assembly for supporting a mask frame to a stud of a panel in a cathode ray tube having a longitudinal tube axis, comprising:
- said mask frame having a rectangular rim disposed in parallel with said tube axis, having a flange vertically extending from a rear end of said rectangular rim toward said tube axis and perpendicular to said tube axis;
- a shadow mask having a skirt fixed on an inside surface of a front end of said rectangular rim, having a first plane perpendicular to said tube axis and passing a central surface of said shadow mask;
- a bracket having a suspending arm joined by a connecting arm to a fixing arm, said suspending arm and said fixing arm spaced apart from each other and disposed in parallel with said tube axis;
- said suspending arm being provided with a hole coupled to said stud;
- said fixing arm fixed on an outside surface of said rectangular rim of said mask frame;
- and
- said connecting arm having a second plane substantially parallel to said first plane of said shadow mask and spaced apart from said first plane of said shadow mask by a first distance, said first distance being greater than a second distance between said first plane of said shadow mask and a third plane passing a center line of said stud.
An assembly in a picture tube having a longitudinal tube axis, comprising:
- a mask frame being a rectangular rim parallel to said tube axis;
- a shadow mask having a skirt fixed on an inside surface of said rectangular rim, having a first plane perpendicular to said tube axis and passing a central surface of said shadow mask;
- a stud formed on and extending inwardly from a sidewall of a panel of said picture tube;
- a bracket having a suspending arm joined by a connecting arm to a fixing arm, being made in a single body, said suspending arm and said fixing arm being flat plates and parallel to each other;
- said fixing arm fixed on an outside surface of said rectangular rim of said mask frame opposite to said shadow mask while said suspending arm coupled to said stud;
- and
- said connecting arm having a second plane substantially parallel to said first plane and spaced apart from said first plane by a first distance greater than a second distance between said first plane of said shadow mask and a third plane passing a center line of said stud.
