ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a base for a computer monitor, more particularly to a pivot base for a liquid crystal display monitor.
2. Description of the Related Art
A conventional notebook computer includes a main board housing and a monitor housing that are hinged to each other. Since friction force is generally used to retain the monitor housing at a desired tilting angle relative to the main board housing, the hinge construction of the conventional notebook computer is not suitable for application to a stand-alone liquid crystal display monitor in view of the relatively large size of the latter. There is thus a need to develop a pivot base that is capable of supporting relatively large liquid crystal display monitors.
SUMMARY OF THE INVENTION
Therefore, the object of the present invention is to provide a pivot base that can serve as a stable and angle-adjustable support for liquid crystal display monitors of different sizes.
According to the present invention, a pivot base for a computer monitor includes a base member, a monitor supporting member and a releasable retaining unit. The base member has a top side and a pair of mounting plates that project upwardly at the top side and that are spaced apart in a transverse direction. The monitor supporting member is adapted for mounting the computer monitor thereon, and is mounted movably between the mounting plates. The monitor supporting member is movable relative to the base member in a first direction for locating the computer monitor in a generally upright position relative to the base member, and in a second direction for locating the computer monitor in an inclined position relative to the base member. The releasable retaining unit is provided on the base member and the monitor supporting member to arrest relative movement therebetween.
