Adjustable keyboard support |
摘要 |
A table top is provided with a vertically adjustable keyboard support platform which is suspended on a parallel linkage assembly. The parallel linkage rotates about a pair of rotatable pivot rods carried by the underneath side of the platform. A gas spring is connected to the linkage to block its rotation when the platform is in a desired lowered position and to aid in returning the platform to a position flush with the table top.
