Aperture mask supported by spring lugs and spring clips

Abstract

In a color TV bulb formed with a panel, a peripheral panel skirt integral therewith, a funnel portion adapted to mate therewith, a frame and aperture mask adapted to be mounted in said frame and secured in spaced relation with the panel; a supporting structure for the aperture mask and frame including peripherally located outwardly extending spring lugs and spring clips attached to the frame respectively operative for xy orientation and Q spacing of the aperture mask. The panel skirt is formed with a selected number of V grooves located each for receiving a corresponding one of the spring lugs and a ledge face spaced away from the inside surface of the panel to cooperatively engage with and support the spring clips. A forward surface of the funnel engages the spring clips to urge same against the ledge face such that the xy orientation and Q spacing of the aperture mask are fixed relative to the panel. .Iadd.

What is claimed is: 
     
       1. In a color television bulb formed with a panel, a peripheral panel skirt integral therewith, a funnel portion adapted to mate with the panel skirt, a frame and aperture mask adapted to be mounted in said frame and secured in spaced relation with the panel; a supporting structure for the aperture mask and frame including: peripherally located outwardly extending spring lugs and peripherally located outwardly extending spring clips secured to the frame and respectively operative for xy orientation and a Q spacing of the mask and frame; the panel skirt being formed with a selected number of V grooves each located so as to receive a corresponding one of the spring lugs; and a ledge face spaced away from an inside surface of the panel to cooperatively engage with and support the spring clips, a forward portion of the funnel adapted to be in spaced relation with the ledge face, spring means engaging each respective spring clip at one end and the forward portion of the funnel at the other when located in said spaced relation for urging each respective spring clip against the ledge face such that xy orientation and Q spacing of the aperture mask and frame are fixed relative to the panel when the funnel and panel skirt are mated. 
     
     
       2. The supporting structure of claim 1 wherein the spring clips and spring lugs are located at about 120° intervals about the periphery of the frame. 
     
     
       3. The supporting structure of claim 1 wherein the spring lugs are located along x and y axes of the frame and the spring clips are located along diagonal axes of the frame. 
     
     
       4. The supporting structure of claim 3 wherein the spring clips and the spring lugs are located in tandem at corners of the bulb along diagonal axes thereof. 
     
     
       5. The supporting structure of claim 1 wherein the spring clips include; a first clip member being attached at one end to the frame and having a free end adapted to rest on the ledge; and a spring member having a forward free end engaging a portion of the free end of the clip and being oriented so as to urge the first clip member in a direction towards the panel, said spring member having a rearward free end being urged against the clip by mating engagement with the forward portion of the funnel. 
     
     
       6. The supporting structure of claim 5 wherein the forward portion of the funnel engages the rearward free end of the spring member and includes; a ledge member lying at an acute angle between about 0° and about 5° with respect to the panel ledge member. 
     
     
       7. The supporting structure of claim 1 wherein the V grooves are axially aligned with the panel skirt. .[.8. The supporting structure of claim 1 wherein the V grooves are circumferentially aligned with the panel 
     
     
        skirt..]. 9. A color television bulb comprising a formed studless panel, including a peripheral panel skirt integral therewith; a funnel portion adapted to mate with the panel skirt, a frame and aperture mask adapted to be mounted in said frame and secured in spaced relation with the panel; a supporting structure for the aperture mask and frame including: peripherally located outwardly extending spring lugs and peripherally located outwardly extending spring clips secured to the frame and respectively operative for xy orientation and a Q spacing of the mask and frame; the panel skirt being formed with a selected number of V grooves each located so as to receive a corresponding one of the spring lugs; and a ledge face spaced away from an inside surface of the panel to cooperatively engage with and support the spring clips, a forward portion of the funnel adapted to be in spaced relation with the ledge face; spring means engaging each respective spring clip at a one end and the forward portion of the funnel at the other when located in said spaced relation for urging each respective spring clip against the ledge face such that xy orientation and Q spacing of the aperture mask and frame are fixed relative to the panel when the funnel and panel skirt are mated.
