  • Height adjustable vertically oriented screen or the like
    Patent number: 7789025
    Abstract: A desk or table assembly includes a support member such as a worksurface, and an upright member, which may be in the form of a privacy screen, adjacent an edge of the worksurface. The upright member is interconnected with the support member using a mounting arrangement including a spring to apply a constant upward biasing force on the upright member. The spring resists downward forces applied to the upright member, and assist upward forces applied to the upright member. The spring counterbalances the weight of the upright member so that the upright member is retained at a desired position when moved to the desired position thereto by either a downward or upward external force applied to the upright member.
