ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to facilitating the moveability of display monitors and the like appliances upon their mounting bases or plates over a surface upon which the base or plate is resting.
BACKGROUND OF THE INVENTION
It is common today to have desk top mounted Cathode Ray Tube (“CRT”) display monitors for personal computers and the like. These are typically mounted on a stand which connects to the main part of the monitor chassis in a fashion in which the chassis is allowed to rotate about a vertical axis and swivel up and down about a horizontal axis. The base of the stand is typically flat on the bottom or hollowed out in a fashion according to the molding process forming the plastic molding of the plastic material forming the base. As the size of the monitor increases, the respective difficulty of moving the base across a desk top or across the top of a housing for a personal or mini computer becomes more difficult.
There is a need, therefore, for a mechanism for facilitating the movement of the base which is easy for the computer user to operate and is sufficient to also prevent the base from moving when movement is not desired.
DESCRIPTION OF RELATED ART
In the known art, CRTs and the like are mounted upon a base or plate which rests generally flat upon the surface on which the appliance attached thereto is resting. Friction makes movement of such an appliance across such a surface difficult, with the difficulty increasing as the appliance becomes larger. As these appliances, e.g., computer monitor CRTs, become larger and more bulky, it is more and more inconvenient to try to move them across the surface upon which their base stand or plate is resting.
SUMMARY OF THE INVENTION
It is, therefore, the aim of the present invention to provide a base stand or base plate for appliances such as computer monitors and the like which facilitates their movement when desired, but maintains the immovability of the base stand or base plate when movement is not desired.
