Patent ID: 7164391

Claim:
An orientation adjusting device, comprising: a base unit; a bracket unit coupled pivotally to said base unit, said bracket unit being pivotable in a vertical plane relative to said base unit; and an angle-adjusting mechanism for adjusting an angular position of said bracket unit relative to said base unit, said angle-adjusting mechanism including a first rotatable unit, a first pivot joint that interconnects said bracket unit and said first rotatable unit so as to permit rotation of said first rotatable unit relative to said bracket unit about a first horizontal axis, a second rotatable unit, at least one second pivot joint that interconnects said base unit and said second rotatable unit so as to permit rotation of said second rotatable unit relative to said base unit about a second horizontal axis parallel to the first horizontal axis, and a telescopic unit that interconnects said first and second rotatable units, and that is operable so as to vary the distance between the first and second horizontal axes, thereby adjusting the angular position of said bracket unit relative to said base unit.
