Abstract

An improved cathode ray tube (“CRT”) positioning apparatus and method for use in a video display terminal. In particular, it solves the problem of precisely locating each of the four corners of the CRT at a predetermined distance from the inner edges of the bezel, such that a predetermined sealing pressure is achieved between the bezel and the CRT.

Claims

1. An improved gaming enclosure comprising, in combination:

a. a cabinet (1),

b. hinge means (6) mounted on the cabinet (1),

b. a front panel (4) mounted for rotation about the hinge means (6),

c. a bezel (2), mounted in an aperture formed in front panel (4), and having bottom edges (5) facing towards the interior of the cabinet (1) when the front panel (4) is closed,

d. a shelf (10) mounted in the cabinet (1),

e. a base (9) mounted on the shelf (10) and having at least two pivots (14),

f. a tilt frame (12) mounted for rotation about pivots (14), and having means to lock the rotation,

g. four separate threaded spacing means, having adjustment dials (20), mounted near four corners of the tilt frame (12),

h. a rimband (16) having four corners connected to the four separate threaded spacing means,

i. a CRT (3) having a display portion mounted within the rimband;

j. a touch screen (3a) mounted on the display portion of the CRT (3), sandwiched in touching contact with the bottom edges (5) of the bezel (2) when the front panel (4) is rotated to close the cabinet (1), whereby, the pressure of the bottom edges of the bezel presses against the touch sensitive screen (3a) with controlled pressure set by the four separate threaded spacing means such that just sufficient pressure is applied to the touch screen to make a liquid tight seal but not so much pressure as to distort the touch screen.

2. A method for controlling the pressure imposed by a front panel (4) mounted bezel (2) with its bottom edges (5) pressing against a touch sensitive screen (3a), which is sandwiched between the bottom edges (5) of the bezel (2) and a display portion of a CRT (3), and where the CRT (3) has been mounted with reference to a tilt frame (12) by four separate threaded spacing means, having adjustment dials (20), mounted near four corners of the tilt frame (12), comprising the steps:

a. measuring the spacing to be closed between each edge of the bezel and the touch sensitive screen,

b. dividing the spacing for each corner by the threads per inch of the threaded spacing means holding the CRT at the corners,

c. rotating each of the four spacing adjustment dials (20) a number of turns to move each of the corners of the CRT to a predetermined position relative to the bottom edges (5) of the bezel (2),

whereby a controlled predetermined pressure between the bottom edges (5) of the bezel (2) is and the CRT applied to the touch sensitive screen (3a).
