Adjustable ergonomic support for computer keyboards

An adjustable support assembly for supporting a keyboard so that the keyboard user's wrists will be in a substantially neutral position when the keyboard user is in an operating position relative to the keyboard, said support assembly comprising

• a support platform having an upper surface extending generally in a plane, a front edge and a rear edge, said front edge being closer to the keyboard user in said operating position than said rear edge,
• a bracket assembly for mounting said platform to a work surface, said bracket assembly having a top end connectable to said work surface and a bottom end, said support platform being connected to said bracket assembly for movement through a range of positions between a first position in which said support platform is proximate said top end of said bracket assembly and a second position in which said support platform is remote from said top end of said bracket assembly,
• a locking mechanism having a locked condition for locking said support platform with respect to said top end said bracket assembly at each position within said range of positions and a released condition for releasing said support platform for movement within said range of positions, and
• movement limiting means for limiting angular movement of said support platform relative to said bracket assembly in said locked condition so that said support platform in said locked condition is always oriented with said front edge higher than said rear edge.

• a bracket assembly for mounting said support platform to a work surface, said bracket assembly including a base fixedly mountable to said work surface and having a front end and a rear end, a first portion connected to said base, and a second portion connected to said support platform, said support platform being movable in a first direction transverse to said plane through a range of positions between a first position in which said support platform is proximate said base and a second position in which said support platform is remote from said base, said support platform being movable in a second direction different from said first direction between a retracted position in which said front edge of said support platform is at a first spaced distance from said rear end of said base and an extended position in which said front edge of said support platform is at a spaced distance from said rear end of said base greater than said first spaced distance,
• a locking mechanism having a locked condition for locking said support platform in fixed positions with respect to said base and a released condition for releasing said support platform for movement with respect to said base, and
• movement limiting means for limiting angular movement of said support platform relative to said base in said locked condition so that said support platform in said locked condition is always oriented with said front edge higher than said rear edge.
