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.
Claims12
A height adjustable desktop system, comprising:
- a work surface defining an underside;
- a foot assembly, including a lock housing defining a first lock notch;
- a linkage system configured to support the work surface through a plurality of height adjustable positions including a lowered position, and wherein the linkage system operably connects the work surface to the foot assembly;
- a first lock assembly configured to maintain the work surface at an individual one of the plurality of height adjustable positions;
- a second lock assembly adapted to secure the work surface in the lowered position, the second lock assembly including:
- a first lock lever including a first arm, the first arm adapted to selectively engage with the first lock notch and thereby securing the work surface in the lowered position, the first lock lever rotatable between a locking configuration and a release configuration, wherein:
- in the locking configuration:
- the first lock assembly maintains the work surface at an individual one of the plurality of height adjustable positions, and
- with the work surface in the lowered position the first arm of the first lock lever is received within the first lock notch to secure the work surface in the lowered position, and
- in the release configuration:
- the first arm is unseated from the first lock notch, and
- the first lock assembly allows for adjustment of the work surface between the plurality of height adjustable positions.
