Height adjustable support for computer equipment and the like

A counterforce mechanism for adjustable furniture and the like, comprising:

• a support adapted to mount said counterforce mechanism in an associated furniture article;
• a drive shaft mounted on said support for axial rotation, and adapted for operable connection with the furniture article to facilitate adjustment of the same;
• a first energy storage device operably connected between said support and said drive shaft, and applying a first axial torque to said drive shaft in a first rotational direction;
• an eccentric mounted on said drive shaft, and rotating therewith;
• and
• a second energy storage device operably connected between said support and said eccentric, and applying a second axial torque to said drive shaft in a second rotational direction opposite to said first rotational direction, thereby defining a resultant counterbalance force which facilitates adjustment of the furniture article.

A height adjustable support for office equipment and the like, comprising:

• a worksurface;
• a base shaped to support said worksurface;
• a guide operably connecting said worksurface with said base for movement between a raised position and a lowered position;
• a drive shaft mounted in said base for axial rotation, and operably connected with said worksurface such that rotation of said drive shaft shifts said worksurface;
• a counterbalance mechanism operably connected between said worksurface and said base, and generating a lifting force which biases said worksurface toward said raised position;
• and
• a brake mechanism retaining said worksurface in a selected position, and including a brake surface rotating with said drive shaft, a flexible line wrapped about at least a portion of said brake surface, and a brake actuator which shifts between a locked position wherein said flexible line is tensed and frictionally engaging said brake surface and preventing rotation of said drive shaft, and an unlocked position wherein said flexible line is slackened and allows said drive shaft to rotate.

A height adjustable support for computers and the like, comprising:

• a worksurface;
• a base;
• a guide operably interconnecting said worksurface and said base for guided motion between a raised position and a lowered position;
• a counterforce mechanism generating a lifting force biasing said worksurface into said raised position;
• and
• an indicator operably connected to said counterforce mechanism and providing a signal that communicates the magnitude of said lifting force to a user.

A height adjustable support for computer equipment and the like, comprising:

• a base;
• a worksurface;
• a pair of spaced-apart legs extending downwardly from said worksurface and slidingly engaging said base;
• first and second lower wheels, each of which is rotatably mounted adjacent a lower end of a selected leg;
• an elongated shaft rotatably mounted to said worksurface and extending between said legs;
• and
• first and second flexible lines, each having an upper end forming a loop around said shaft above said lower wheels, each of said upper ends including a resilient tension member connecting said upper ends to said base, a lower end of said first line wrapping at least partially around said first lower wheel and a lower end of said second line wrapping at least partially around said second lower wheel, each cable being fixed to said base such that rotation of said shaft tenses a portion of each of said flexible lines and evenly raises each side of said worksurface without tipping or binding.
