Abstract
In one example, a height adjustable desktop system is described that can include a work surface, a foot assembly and a linkage assembly that adjustably connects the work surface to the foot assembly allowing vertical adjustment of the work surface. The linkage assembly can include a pair of adjustment assemblies, each having a transverse linkage that maintains the work surface in a horizontal orientation as the work surface is elevated or lowered. A biasing mechanism, such as an extension spring or a torsion spring, biases the work surface toward the elevated position.
Claims20
A height adjustable desktop system, comprising:
- a first platform defining an underside and including a glide rod and a support bracket positioned on the underside of the first platform;
- a foot assembly including at least one foot bracket;
- an adjustment assembly including:
- a glider slidable on the glide rod between a first position proximate to a first end of the support bracket and a second position distal to the first end of the support bracket;
- a first linkage rotatably connected to the glider and rotatably connected to the foot bracket, wherein the first linkage is rotatable within a first plane;
- a second linkage rotatable within a second plane parallel to and offset from the first plane;
- and
- a transverse linkage rotatably connected to the support bracket and rotatably connected to the second linkage;
- a handle movably coupled to the underside of the worksurface;
- a lock assembly including:
- the glide rod;
- the glider;
- the handle;
- and
- wherein the lock assembly includes an engaged configuration and a disengaged configuration:
- in the engaged configuration, the lock assembly immobilizes linear translation of the glider with respect to the glide rod and the handle,
- in the disengaged configuration, the lock assembly allows the linear translation of the glider with respect to the glide rod and the handle, and
- wherein movement of the handle changes the lock assembly between the engaged configuration and the disengaged configuration;
- and
- wherein the glide rod extends through first and second through-holes of the glider, wherein the first through-hole has a circular profile, and the second through-hole has a non-circular profile.
