Touch screen mounting assembly
First Claim
1. For use in attaching a touch screen to a video display having a plurality of outwardly extending mounting ears, an assembly comprising:
- a touch screen assembly including a frame having openings which can be aligned with the mounting ears, deformable members received in the openings, and a rigid transparent plate seated against the surface of the frame facing the display, said plate having a plurality of force sensitive-transducers mounted on the plate surface facing the display;
means for securing the touch screen assembly to the display comprising a plurality of studs, each having an end portion which can be secured to one of the mounting ears and a post portion which extends through one of the openings in said frame, and means for holding the frame on the posts, said holding means comprising a plurality of coil springs and a plurality of fastening elements which are attached to the distal ends of the posts to trap the coil springs on the posts, said fastening elements being adapted to compress the coil springs to bias the touch screen assembly toward the display.

Abstract
A piezoelectric touch screen assembly can be attached to mounting ears on an ordinary CRT assembly. The touch screen assembly includes a frame, a glass plate which is seated on a gasket at one surface of the frame and a plurality of piezoelectric elements which are bonded to the glass plate and are "trapped" between the CRT face and the glass plate. Studs extend outwardly from the CRT ears through openings in the frame. Coil springs are placed on the studs and are trapped by washer nuts to load the touch screen assembly toward the CRT by a predetermined amount. Grommets with a unique cross sectional configuration are mounted at the openings through the frame. The grommet is designed to provide minimal resistance to movement of the touch screen assembly toward or away from the CRT face but greater resistance to movement of the assembly in other directions.
