ABSTRACT:

RELATED APPLICATION
This application claims the benefit of priority under 35 U.S.C. § 119(a) of Taiwan Patent Application No. 089118771, titled “Base Capable of Adjusting the Elevation of a Panel,” filed on Sep. 11, 2000.
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a base, and more particularly to a base capable of adjusting the elevation of a display panel.
2. Description of the Related Art
FIG. 1
illustrates a schematic diagram of a prior art base
12
used for supporting a panel
10
. As shown in
FIG. 1
, the prior art base
12
is located on the backside of the panel
10
for supporting the panel
10
and allowing the panel
10
to stand on any platform. The base
12
comprises a fixed flap
14
, a supporting flap
16
, and a hinge
18
. The fixed flap
14
is attached to the backside of the panel
10
, and the hinge
18
connects the fixed flap
14
and the supporting flap
16
. Both the fixed flap
14
and the supporting flap
16
can turn about a shaft of the hinge
18
such that the panel
10
can stand on any platform and be positioned at a specific elevation.
As shown in
FIG. 1
, the prior art base
12
provides the panel
10
with only a single, fixed elevation such that the users can only view the panel
10
at a fixed viewing angle. However, different users view the panel
10
at different elevation levels. Thus, the prior art base design fails to provide users with the comfort they desire when they view the panels. This problem is exacerbated for those who need to view the panel for an extended period of time, which may result in severe fatigue of the eyes and the muscles.
SUMMARY OF THE INVENTION
This invention provides a base capable of adjusting the elevation of a panel to allow a user to flexibly adjust the elevation of a panel when the user views the panel to provide the user with greater comfort. In addition to allowing the user to adjust the elevation of a panel, the base can be freely mounted on or disassembled from the panel such that the user has more use options with the base design.
The foregoing is a brief description of some of the deficiencies in the prior art and the advantages of this invention. Other features, advantages, and embodiments of the invention will be apparent to those skilled in the art from the following description, the accompanying drawings and appended claims.
