Abstract:
An adjustable screen lift arm includes a support frame assembly with a frame base, a balance adjustment mechanism including a gear set consisting a drive gear and a sector-like driven gear, a gear rack meshed with the drive gear and a spring connected between the frame base and the driven gear, and a holder block assembly has a holder block body that combined with the gear rack and a first sliding rail, the other side combined with a second sliding rail. When the holder block body is moved vertically, the gear rack rotates the drive gear, causing the driven gear to stretch or compress the spring so that the arm of force is relatively changed to offset the spring force of the spring, enabling the holder block assembly to be freely adjusted to the desired elevation and then automatically positioned.

Claim (Index 1):
An adjustable screen lift arm, comprising:\n a support frame assembly comprising a frame base and an outer cover, said frame base defining an accommodation chamber and a front opening in communication with said accommodation chamber, said outer cover being fastened to said frame base over said front opening, said outer cover defining an upper opening in communication with said front opening and said accommodation chamber; a balance adjustment mechanism mounted in said accommodation chamber of said frame base, comprising a gear set, a gear rack and a spring, said gear set comprising a drive gear and a driven gear made in the form of a sector and meshed with said drive gear, said gear rack being meshed with said drive gear, said spring being connected between said frame base and said driven gear; and a holder block assembly comprising a holder block body, a first sliding rail and a second sliding rail respectively mounted to two opposite lateral sides inside of said frame base, a connection plate affixed to a back side of said holder block body and inserted through said upper opening of said outer cover into the inside of said frame base with one lateral side thereof connected to said gear rack and said first sliding rail and an opposite lateral side thereof connected to said second sliding rail; wherein when said holder block body of said holder block assembly is moved vertically by an external force, said gear rack is driven to rotate said drive gear of said gear set, causing rotation of said driven gear to stretch or compress said spring; during rotation of said driven gear, the length of an arm of force is relatively changed to offset the elastic restoring energy of said spring, enabling said holder block assembly to be freely adjusted to the desired elevation and then automatically positioned in the adjusted position.
