Abstract

A movable display assembly is incorporated in the car stereo for adjusting the screen viewing angle of the LCD. The movable display assembly comprises a semi-spherical display means and a guide shaft for guiding the display means in any direction within a semi-circular cavity which is formed in the forwardly opening of the front panel of the car stereo. The semi-spherical display means includes a convex rear wall and an LCD constituting the front face of the display means. The guide shaft extends horizontally from the rear face of the display means and is loosely fitted in an opening formed in the cavity. A frictional means is provided in order to hold the movable display means in place.

Claims

1. An angle adjusting apparatus for a display of a car stereo having a main body to be incorporated in the dashboard of a car and a front panel;

a recessed semi-spherical wall formed in a forwardly facing wall of the front panel and having a circular opening formed in the center of the recessed wall;

a display assembly including a substantially semi-spherical support means, said support means including a first substantially semi-spherical rear wall member and a second substantially semi-spherical rear wall member extending rearward from the first rear wall member, said first rear wall member having a larger radius of curvature than said second rear wall member;

said display assembly further including an LCD attached to a front of the first semi-spherical rear wall member, and a guide shaft extending rearward from the second rear wall member, said guide shaft being movably received in the opening in the recessed wall to movably guide the display assembly so as to adjust the viewing angle of the LCD of the display assembly; and

frictional support means mounted on the guide shaft, said support means including a frictional contact plate closely attached to the recessed wall adjacent the opening, and means for resiliently urging the contact plate against a rear surface of said recessed wall.

2. The apparatus of claim 1, wherein said urging means includes a compression spring, washer, and a screw mounted to said guide shaft.

3. The apparatus of claim 1, wherein said first rear wall member is retained within the recessed semi-spherical wall.

4. The apparatus of claim 3, wherein the curvature of said recessed semi-spherical wall is similar to the curvature of said first rear wall member.

5. The apparatus of claim 3, wherein said urging means includes a compression spring, washer, and a screw mounted to said guide shaft.

6. The apparatus of claim 1, wherein the curvature of said recessed semi-spherical wall is similar to the curvature of said first rear wall member.

7. The apparatus of claim 1, wherein the radius of curvature of said second rear wall member is smaller than the radius of curvature of said recessed semi-spherical wall.

8. The apparatus of claim 7, wherein the curvature of said recessed semi-spherical wall is similar to the curvature of said first rear wall member.
