ABSTRACT:
An articulated support assembly for a computer keyboard. The assembly includes a generally U shaped rigid support member, and a platform for supporting the keyboard pivotably mounted on a central portion of the support member. Projecting end portions of the support member are pivotably mounted on attachment members fixed to the bottom of a table or desk top. A releasable friction clutch restricts pivotal movement of the platform around the central portion of the support member. A releasable ratchet assembly prevents revolving movement of the central portion toward a lowered position relative to the attachment members. A switching mechanism can be manually activated to release the ratchet assemblies and the friction clutch so that the position and orientation of the platform relative to the table or desk top can be adjusted.
