Abstract

An adjustable support for a display has a base, a parallel link mechanism that has its lower end pivoted to the base, and a plate that is attached to the upper end of the parallel link mechanism and carries the display. Springs are mounted inside the base and are connected between the base and the parallel link mechanism to counterbalance the weight of the display so that the parallel link mechanism and the display can be easily adjusted in height. The spring mechanism includes an adjusting screw that permits the spring to be set for displays of differing weight. The plate is pivotally attached to the upper end of the parallel link by means of a clamp mechanism so that the tilt of the display can be adjusted.

Support for CRT Display with Height and Tilt Adjustment

An adjustable support for a display has a base, a parallel link mechanism that has its lower end pivoted to the base, and a plate that is attached to the upper end of the parallel link mechanism and carries the display. Springs are mounted inside the base and are connected between the base and the parallel link mechanism to counterbalance the weight of the display so that the parallel link mechanism and the display can be easily adjusted in height. The spring mechanism includes an adjusting screw that permits the spring to be set for displays of differing weight. The plate is pivotally attached to the upper end of the parallel link by means of a clamp mechanism so that the tilt of the display can be adjusted.

Figure 1 is a perspective of the support. A base 2, and three links 3, 4 (hidden in Figure 1) and 5 cooperate to form a parallel linkage. Links 3 and 4 remain parallel with each other, and link 5 remains at a fixed angle to the base. Link 3 is pivoted to the base at a point 6 and is pivoted to link 5 at a point 7. Link 4 is pivoted to the base at a point that is not shown and is pivoted to link 5 at a point 8 that includes a clamp that locks the parallel mechanism with the display at a selected height. A similar clamp at a pivot 9 locks a plate 10 to carry the display at a selected tilt.

Figure 2 is a section view that shows the components already described and shows a spring 11 that is anchored at one...
