Abstract

A tilting support for a display includes a screw that transmits a tilting force between a lower base and an upper support that is pivotally connected to the lower base and carries the display tube. The lower end of the screw is connected to the lower base by a nut that is turned by a thumb wheel that is rotatably mounted on the lower base. The upper end of the screw is hinged to the upper support so that the screw does not turn with the thumb wheel but is raised or lowered as the thumb wheel is turned. The hinge between the screw and the upper tilting carriage permits the change in the angle between the screw and the upper support when the display is tilted through a range of positions.

Pivoting Support for Display With Thumb-Wheel Turning Nut on Nonrotating Screw

A tilting support for a display includes a screw that transmits a tilting force between a lower base and an upper support that is pivotally connected to the lower base and carries the display tube. The lower end of the screw is connected to the lower base by a nut that is turned by a thumb wheel that is rotatably mounted on the lower base. The upper end of the screw is hinged to the upper support so that the screw does not turn with the thumb wheel but is raised or lowered as the thumb wheel is turned. The hinge between the screw and the upper tilting carriage permits the change in the angle between the screw and the upper support when the display is tilted through a range of positions. In addition, the hinge is made slideable in the front to back direction of the upper support so that the axis of the screw and thumb wheel remain fixed as the display is tilted.

Background

A display commonly has a cathode ray tube and a support for holding the tube in a position that is selected by a user for comfortable viewing. Some supports have a lower base that is rotatable in a horizontal plane. An upper support carries the display tube and is tiltably mounted on the lower support.

Implementation

The drawing is an exploded view of some of the components of a display station. The lower base includes a component 2 that carries support arms 3 and 4 and a thumb-wheel mechanism 5. The upper support inc...
