Adjustable Mount for Display

A cathode ray tube (CRT) mount is adjustable in height, tilt and rotation. Gas cylinders are used to assist the operator in the height adjustment. The gas cylinders and main support arm are mounted on a rotational base.

In Fig. 1, rotating base 5 supports the adjustable height system. Five support feet 11 are attached to rotate plate 10. Rotate plate 10 is attached to rotating base 5 at shaft 8. Main support arm 12 is attached to base 5 at pivot point 1. Arm 12 is shown in a lowered position in dashed lines.

Gas cylinder 4 provides the lifting force for support arm 12. Cylinder 4 is attached to base 5 at pivot point 2. Cylinder 4 is attached arm 12 at pivot point 3. As arm 12 moves to the raised position gas cylinder 4 moves to an extended position. To control unwanted motion by lifting cylinder 4 a lock can be provided at any of the three pivot points 1, 2 or 3.

Fig. 2 shows a friction mount 6 for the CRT at the end of arm 12. Tilt function for the CRT is accomplished by using two friction washers 14 on either side of arm 12, a spring washer 15, adjusting nut 16, and shaft 18. These parts are locked to CRT 7. Nut 16 loads washer 15 against washer 14 to the designed tilt force. Pin 17 (Fig. 2) limits the tilt motion (+15 degrees to -5 degrees).

Depending upon the weight of CRT 7, multiple gas cylinders 4 may be attached. The operator should see a lifting force of less than 5 pounds. A pair of cylinders could be mounted so that one cyl...
