Abstract: A height adjustable work platform apparatus. The height adjustable work platform apparatus includes a frame slidably supporting a cantilevered platform for supporting articles thereon. The platform is slidably engaged with a pair of rails disposed on the frame, which allows the platform to be adjusted vertically. The apparatus further includes a spring-biased pin disposed on the undersurface of the platform that is configured to engage complementary slots disposed on the surface of the upright members of the frame. A vertically-biased pulley system internal to the frame biases the platform to a raised position in order to reduce the amount of effort required to lift the platform. The frame of the apparatus includes a lower portion that is sized and shaped to receive the frame of the platform, thereby allowing the platform to rest flush against the lower portion when fully lowered.

Abstract: A height adjustable work surface is provided, which includes an L-shaped frame supporting a cantilevered platform adapted to support computer and work space items thereon. The frame includes an upstanding rail portion and a horizontal base support, whereby the rail portion slidably supports a work surface platform above the base support. The rail portion and base support are U-shaped members, whereby a first and second rail is provided to support the work space platform. Cam locks are provided to lockably secure the platform in a given position, whereby the platform will not freely slide until unlocked and will support load thereon. An internal spring mechanism biases the platform to reduce lifting load requirements during adjustment of the platform. Overall, the device provides a means to adjust the elevation of work surface for a seated or standing user.
