Abstract

This invention relates a swivel mechanism for a monitor of a laptop computer and in particular to one utilizing four tightly fitted axles in the same direction to be its horizontal axis and a tightly fitted upright axle to be its vertical axis so as to enable the monitor to rotate with respect to the horizontal and the vertical axes when pushed by the user thereby widening the visible range and thus, increasing the working efficiency and the feasibility as well.

Claims

1. A swivel mechanism for a monitor of a laptop computer comprising:

a fixed seat having a vertical axle at the bottom thereof, a spring and a positioning block, said positioning block being disposed on a fixed frame rigidly mounted within a main body of the laptop computer and having a vertical hole for receiving the spring, vertical axle tightly fitted within said spring thereby enabling said fixed seat to rotate with respect to the fixed frame in said positioning block; and

a horizontal axle having four longitudinal axles extending in the same direction, four springs, two positioning plates, two side covers and a protective cover, each longitudinal axle being formed with a fixed block wherein a first one extends through its respective fixed block thereof to connect to a threaded hole of said fixed seat and kept in position by a screw, a second one passes through its respective fixed block thereof to connect to another threaded hole of said fixed block, and the remaining two are disposed beside an inner side of the monitor, said springs of the horizontal axle being connected at their outer ends with the side covers;

whereby the monitor may be rotated with respect to a vertical axis and a horizontal axis when pushed by a user thereby widening vision range.

2. The swivel mechanism as claimed in claim 1, wherein said vertical axle and said longitudinal axles are formed with longitudinal raised lines in order to increase rotational friction when rotating on said springs.
