A rolling cart for a computer and flat panel display includes a base with plural castered dual wheels, a mounting pole projecting upward from the base, at least one pole mounting bracket, a pivot support bracket supported by the pole mounting bracket and securing a support arm which is suitable for supporting a flat panel display. Another pole mounting bracket supports another pivot support bracket and secures a second support arm having a pivot/brake assembly suitable for supporting a keyboard. Additionally, the cart supports a CPU bracket and a UPS mounting bracket. The pivot/brake assembly includes a frictional assembly and a brake assembly. |

DETAILED DESCRIPTION The general purpose of the present invention is a multi-jointed, pivoted support arm for support and position of a flat panel display screen or a keyboard.
According to one embodiment of the present invention, there is provided a multi-jointed and pivoted support arm for positioning of a flat panel display screen including a mounting bracket, an arm azimuthal pivot, an elevational pivot, an adjustable load counterbalance system,a display pivot, a display rotation pivot and an interface coupling acting in concert to support and provide positioning for a flat panel display screen or any other desired object such as a keyboard.
The frictional pivot mount is an unique tilt resistive device that relies on the unique properties of a family of polymer materials having a static and dynamic coefficient of friction which substantially is identical, such as Delrin or other ultra high molecular weight polyethylene (UHMWPE) materials.
The static and dynamic coefficients of UHMWPE materials, such as utilized in the washers, and the unique result of this frictional pivot tilt restraining device is that a flat panel display remains in any tilt position selected by the user.
If the user wishes to tiltingly reposition the flat panel display upwardly or downwardly, or any other position, the flat panel display must be manually repositioned to overcome the frictional pivot tilt restraining device.
Once the flat panel display is tilted to a different selected position, the unique frictional pivot tilt restraining device resistably restrains the flat panel display in the new position as selected.
Sufficient friction to maintain position of the flat panel display during use is provided, and yet allows easy "breakaway" release to reposition the flat panel display to a new operating position or to the storage position.
The unique characteristics of the polymer material allows smooth tilt adjustment of the frictional pivot tilt mechanism, and yet, provides a constant frictional memory for the preset position of the flat panel display
