Display assembly having display supported on casing to be controllable in attitude

A display assembly to be mounted on a ceiling portion of a space comprising:

• a casing having a downwardly directed face and a receptacle cavity opening into said face;
• a display unit having a display screen to be received within said receptacle cavity;
• and
• connecting means for connecting said display unit to said casing to be controllable in attitude, said connecting means having a rotary body rotatable with respect to said casing about a first axis substantially perpendicular to said face of said casing, said display unit being supported on said rotary body for pivoting about a second axis extending perpendicular to said first axis, whereby when said rotary body is placed at a predetermined rotational position, said display unit is able to be pivoted relative to said rotary body to be received within said receptacle cavity;
• wherein said receptacle cavity includes at least one inner side wall, and when said rotary body is placed at said predetermined rotational position, said rotary body has a wall surface that is substantially flush with one of the inner side walls of said receptacle cavity and said second axis becomes parallel to said one inner side wall of said receptacle cavity, to thereby enable said display unit to be received in said receptacle cavity;
• and
• said easing is formed with a circular cavity formed to extend from said face of said casing to an inner bottom surface of said receptacle cavity, said rotary body is of a generally disc shape and has a first half-disc portion having a lower surface lying substantially flush with said face of said casing and a second half-disc portion having a lower surface lying substantially flush with said inner bottom surface of said receptacle cavity, said rotary body is rotatably supported within said circular cavity, and said first and second half-disc portions are arranged at opposite sides across a boundary wall lying therebetween and providing said wall surface of said rotary body.
