Abstract

A ceiling LCD mounting structure includes a mounting base fixedly fastened to the ceiling of a car, the mounting base defining a bottom receiving chamber, a pivot shaft coupled between two clamping plates in a top side of the mounting base and held down by at least one holding down plate and adapted to be rotated relative to the clamping plates, and a LCD holder frame holding a LCD (liquid crystal display), the LCD holder frame having mounting flange inserted through an opening in the mounting base and fastened to the pivot shaft for enabling the LCD holder frame to be turned in and out of a bottom receiving chamber of the mounting base and positioned in one of a series of angular positions.

Claims

1. A ceiling LCD mounting structure comprising:

a mounting base fixedly fastened to the ceiling of a car, said mounting base comprising a bottom receiving chamber defined in a bottom side wall thereof, two clamping plates fixedly mounted in a top side wall thereof, and at least one holding down plate;

a pivot shaft coupled between said clamping plates and held down by said at least one holding down plate and adapted to be rotated relative to said clamping plates and positioned in one of a series of angles; and

a LCD holder frame holding a LCD (liquid crystal display), said LCD holder frame having mounting means fastened to said pivot shaft for enabling said LCD holder frame to be turned in and out of said bottom receiving chamber of said mounting base.

2. The ceiling LCD mounting structure of claim 1 wherein said clamping plates each have a substantially U-shaped clamping arm clamped on said pivot shaft, said U-shaped clamping arm comprising two vertically spaced and transversely extended positioning grooves for holding said pivot shaft in one of a series of angular positions.

3. The ceiling LCD mounting structure of claim 2 wherein said pivot shaft comprises a plurality of longitudinal positioning ribs symmetrically disposed around two distal ends thereof for engagement with the positioning grooves in the U-shaped clamping arms of said clamping plates to hold said pivot shaft in one of said series of angular positions.

4. The ceiling LCD mounting structure of claim 1 wherein said at least one holding down plate each has a Z-shaped profile.

5. The ceiling LCD mounting structure of claim 1 wherein said pivot shaft comprises a plurality of mounting holes for the mounting of the mounting means of said LCD holder frame.

6. The ceiling LCD mounting structure of claim 5 wherein the mounting means of said LCD holder frame comprises a top mounting flange inserted through an opening in said mounting base, said mounting flange having a plurality of mounting holes respectively fastened to the mounting holes on said pivot shaft by screws.
