Adjustable keyboard support

A keyboard support device for a base structure, comprising:

• a keyboard support platform adapted for receiving a keyboard thereon;
• a support arm having a first end adapted for pivotally attaching said support arm to said keyboard support platform, and a second end adapted for pivotally attaching said support arm relative to the base structure;
• a locking pivotal assembly including a coil spring having a locked position for restricting pivotal movement of said keyboard support platform relative to the base structure, and an unlocked position permitting pivotal movement of said keyboard support platform relative to the base structure;
• a release mechanism operable to adjust said coil spring from said locked position to said unlocked position;
• and
• a first locking pivotal assembly at said first end of said support arm, said first locking pivotal assembly including a first coil spring having a first locked position for restricting pivotal movement of said keyboard support platform relative to said support arm, and a first unlocked position permitting pivotal movement of said keyboard support platform relative to said support arm;
• a second locking pivotal assembly at said second end of said support arm, said second locking pivotal assembly including a second coil spring having a second locked position for restricting pivotal movement of said support arm relative to the base structure, and a second unlocked position permitting pivotal movement of said support arm relative to the base structure;
• a release mechanism operable to adjust said first coil spring from said first locked position to said first unlocked position;
• and operable to adjust said second coil spring from said second locked position to said second unlocked position.

• a wrist support unit connected to said keyboard support platform, said wrist support unit having a vertically adjustable upper piece, and a rack and pinion adjustment mechanism operatively connected to said upper piece;
• and
• first and second racks attached to said adjustable upper piece, a lower piece, a shaft disposed for rotation in said lower piece, and first and second pinion gears disposed on said shaft and operatively engaged with said first and second racks.

A locking pivotal link between a keyboard support platform and a base unit, comprising:

• a pivotal joint between the keyboard support platform and the base unit, including a cylindrical element having an outside surface, said cylindrical element rotatably interconnecting the keyboard support platform relative to the base unit;
• a coil spring disposed around said cylindrical element,
• said coil spring having a diameter sized for creating an interference fit between said coil spring and said cylindrical element;
• said coil spring having a first end and a second end, said first end being fixed in position relative to said cylindrical element;
• and
• a release mechanism connected to said second end, said release mechanism adapted for movement of said second end to change said diameter and relieve the interference fit between said coil spring and said cylindrical element, said release mechanism including a first release paddle and a second release paddle, a first cable and pulley system disposed between said first release paddle and said second release paddle, and a cable connection between said first cable and pulley system and said second end.
