ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a hinge for a notebook computer and, more particularly, to a hinge which prevents a liquid-crystal display from quivering even after the lid of a notebook computer is opened.
2. Description of Related Art
It is well known that a notebook computer is small in size and portable. One factor contributing to the smallness and portability is the use of a liquid-crystal display (LCD). In the notebook computer, the liquid-crystal display is usually formed on an inner of a lid, which is hinged on a main body of the computer by means of hinges.
Now many hinges for the notebook computers are known. As shown in
FIG. 3
, such a hinge generally includes a leaf (
30
) having a pair of tubular portions (
31
) and a wing (
32
) extending from a side of the leaf (
30
) to be attached to a rack (
40
) formed in a lid (
50
) of a computer. In addition, there is further provided a base (
33
) that has an upright slab (
34
) defining a through-hole (
340
) in alignment with the tubular portions (
31
) of the leaf (
30
). The leaf (
30
) and the base (
33
) are pivotally connected to each other, by means of a pintle (
35
) which extends through the through-holes (
340
) of the base (
33
) into the tubular portions (
31
) of the leaf (
30
).
Once the leaf (
30
) and the base (
30
) are fastened by screws (
36
), to the lid (
50
) and the main body (not shown) of the computer respectively, the lid (
50
) is hinged on the main body. Then a liquid-crystal display appears as soon as the lid (
50
) is turned open.
With the conventional hinge, it has been found that liquid-crystal display on the lid (
50
) quivers after the lid (
50
) is opened. This reduces the useful life of the hinge(s) and also of a flat wire electrically connecting the display to the main body.
Therefore, it is an objective of the invention to provide a hinge to mitigate and/of obviate the aforementioned problem.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a hinge which prevents a liquid-crystal display from quivering after the lid of a notebook computer is opened.
