A method and apparatus for molding a video display screen bezel to a video display device, such as a CRT, is disclosed. The bezel is molded in such a way as to eliminate the need for fasteners between the bezel and the CRT and between the bezel and a housing or some other structural support. The molded bezel also prevents any undesirable shifting of the CRT with respect to the bezel due to accidental dynamic loads. The molding material conforms to the surface of the CRT compensating for any dimensional variations in the CRT while minimizing the size of the bezel. Molded within the bezel is a compensating means which absorbs stresses generated by the molding material both during and following the molding process which might otherwise be exerted on the CRT.

A shock and vibration isolating device is provided for mounting a component on a supporting structure while absorbing with substantially equalized reaction force relative movement between the component and the supporting structure occurring in all of the three mutually orthogonal planes in which the dynamic loading of the component can occur. The device includes an open frame planar spring element lying in a plane parallel to one of the mutually orthogonal planes, the spring element composed of a core member of a low creep, high modulus, metal and a shell member of a plastic exhibiting high internal dynamic loss substantially encompassing said core. A first cantilever section adjacent a first end is mounted to the supporting structure; a second cantilever section parallel to the first cantilever section adjacent a second end is mounted to the component; and a bridge section connects the first and second cantilever sections and is perpendicular thereto. The ratio of the lengths of the first cantilever section to the second cantilever section to the bridge section is substantially 1.84:1.09:1.00.

Uniform spatial action shock mount

A cathode ray tube mounting apparatus and method for use in a video display terminal or television receiver. An adhesive is applied to either the inside perimeter of the bezel of the cabinet or to the perimeter of the front surface of the cathode ray tube. The cathode ray tube and bezel are then placed in contact and pressed together. Before the adhesive has set, the position of the cathode ray tube is adjusted to align the cathode ray tube with the horizontal center line of the cabinet. In another embodiment, a sheet of material is attached to the inside of the front portion of the cabinet. The adhesive is applied to either the sheet of material or to the front surface of the cathode ray tube. The cathode ray tube and front portion of the cabinet are then mated as before. The sheet of material is used to compensate for any thermoexpansion mismatch between the cathode ray tube and the cabinet.
