CONVERTIBLE SIT AND STAND WORKSTATION
20170013957 · 2017-01-19 ·

A workstation for alternatively configuring a conventional desk for use while sitting and use while standing. The workstation includes an extendable column formed of multiple nested sections. The nested sections are configured to telescope such that the column can be extended. The workstation is configured to support a monitor and a tray. The extendable column contains a counter balance mechanism that is configured to resist collapsing of the column. A movement coupling mechanism is provided that it is such that motion of the first section relative to the second section is transmitted to the third section such that the third section moves a corresponding amount relative to the second section.

Methods to improve rigidity of vertically oriented drawer slides
20170007016 · 2017-01-12 ·

Methods include direct and indirect communication of a lifting force to the middle slide of each drawer slide that counteracts the effects of gravity and maintains the maximum elevated position of the middle slide, where said methods cooperating with over-length drawer slides enable further improvement in rigidity.

HEIGHT-ADJUSTABLE TABLE

A height-adjustable table includes a frame supporting a work surface; a pair of lower legs supporting the frame; a pulley mechanism coupling the frame and the lower legs for vertically moving the frame relative to the lower legs; and a spring located within a passage extending through the frame. The spring has a fixed end secured to the frame and a movable end movable relative to the frame over a first distance for exerting a force over the first distance. The table further includes a block-and-tackle assembly located within the passage. The block-and-tackle assembly couples the movable end of the spring to the pulley mechanism for transferring the force exerted by the spring over the first distance to vertical movement of the frame relative to the lower legs over a second distance greater than the first distance.

ADJUSTABLE LIFT SYSTEM
20250302190 · 2025-10-02 ·

A lift system is designed for raising and lowering a load. The lift system can include a movable portion in sliding engagement with a fixed portion. The lift system can be configured to translate the load coupled to the movable portion relative to the fixed portion. The lift system can also include a counterbalance mechanism having an arm rotatably coupled to the fixed portion, and one or more springs coupled to the arm and the fixed portion. The arm can be operably coupled to the movable portion through a cord. As the movable portion translates, the arm can rotate to deflect the one or more springs to provide a lift force to offset the weight of the load.
