## Background
FIELD OF THE INVENTION
Various embodiments of the present invention generally relates to a mounting bracket. More particularly, particular embodiments of the present invention relate to a conversion bracket that allows a Cathode Ray Tube monitor caddy to be compatible for use with flat panel monitors.
BACKGROUND OF THE INVENTION
Computer systems typically include at least a monitor, a keyboard, a central processing unit (CPU), a chipset, and memory. Depending on the configuration of the computer system, the monitor may be attached to the rest of the computer system by only a Video Graphics Array cable, Digital Video Interface cable, or similar connection device. Examples of common monitor types include Cathode Ray Tube (CRT) and Liquid Crystal Display (LCD) monitors. LCD monitors are often referred to as “flat panel monitors.”
Flat panel monitors are becoming increasingly popular with consumers. They typically offer better image quality, have a smaller footprint, and consume less electricity than Cathode Ray Tube (CRT) monitors. Flat panel monitors are now outselling their CRT counterparts by a wide margin. As consumers transition from CRT monitors to flat panel monitors, mounting solutions that were used with computer systems having CRT monitors are becoming obsolete. Mounting solutions are typically used to mount computer systems for user access in laboratories, factory floors, offices, and other work areas.
Mounting solutions for computer systems having CRT monitors were not originally designed to support flat panel monitors. Thus, if a consumer desires to upgrade her old CRT monitor to a new flat panel monitor, she will also have to invest in a mounting solution that is compatible with flat panel monitors. Accordingly, a need exists in the art for flat panel mounting solution which can utilize existing CRT mounting solutions.
SUMMARY OF THE INVENTION
A conversion bracket is provided for allowing a mounting solution intended for a Cathode Ray Tube monitor to be used with a computer system having a flat panel monitor. In an embodiment, the conversion bracket comprises a two prong mounting adaptor, a first base portion coupled to the mounting adaptor, a monitor mounting plate coupled to the first base portion, a second base portion coupled to the mounting plate, and a flange coupled to the second base portion. The flange is at least substantially perpendicular (e.g., perpendicular) to the first base portion, the mounting plate, and the second base portion.
In another embodiment, a conversion bracket comprises a base portion, a two prong mounting adaptor, a monitor mounting plate, and a flange. The two prong mounting adaptor is coupled to a first end of the base portion. The flange is coupled to the second end of the base portion. The monitor mounting plate is positioned intermediate to the first end and the second end of the base portion.
The foregoing is a summary and thus contains, by necessity, simplifications, generalizations and omissions of detail; consequently, those skilled in the art will appreciate that the summary is illustrative only and is not intended to be in any way limiting. Other aspects, inventive features, and advantages of the present disclosure, as defined solely by the claims, will become apparent in the non-limiting detailed description set forth below.
