Abstract
An elastic member for supporting the shadow mask of a color picture tube comprises a fixing portion having a welding point which is moved from the bottom end to the center or closer to the top end thereof, so that the fixing portion is fixed to the frame of the color picture at the welding point, a sliding portion and a connecting portion to be attached to the panel pin of a face panel through a connecting hole.
Claims6
An elastic member for supporting a shadow mask of a color picture tube having a panel, comprising:
- a fixing portion including a welding point which is located at less than a half of said fixing portion's length from a top end thereof and an extended portion movably extending from said welding point to a bottom end of the fixing portion,
- said extended portion having a length which is more than a half of said fixing portion's length,
- said fixing portion being fixed to a mask frame of the color picture tube at said welding point;
- a connecting portion having a connecting hole through which said elastic member is attached to a panel pin formed on the inner side of the panel;
- and
- a sliding portion which connects said fixing portion and said connecting portion, so as to form a one-piece elastic member;
- wherein said extended portion of the fixing portion reduces permanent deformation of the elastic member.

A two-piece elastic member for supporting a shadow mask of a color picture tube having a panel, comprising:
- a first elastic member including:
- a connecting portion attached to a mask frame of the color picture tube,
- a sliding portion which connects said connecting portion and a fixing portion, and
- said fixing portion having a welding point which is located at less than a half of said fixing portion's length from a top end thereof and an extended portion movably extending from said welding point to a bottom end of the fixing portion,
- said extended portion having a length which is more than a half of said fixing portion's length;
- and
- a second elastic member symmetrically attached to said first elastic member including:
- a fixing portion welded to the fixing portion of said first elastic member,
- a sliding portion, and
- a connecting portion having a connecting hole through which said second elastic member is attached to a panel pin formed on the inner side of the panel;
- wherein said fixing portion of the second elastic member is welded to the fixing portion of the first elastic member at said welding point of the first elastic member, said extended portion of the fixing portion of the first elastic member reducing permanent deformation of the two-piece elastic member.
