Abstract

A height adjustable device including a counterbalance mechanism configured to be affixed adjacent to a rear portion of a vertical support member, a worksurface configured to be affixed adjacent to a front portion of the vertical support member, and a mounting member configured to slidably couple the worksurface to the counterbalance mechanism; wherein a portion of the mounting member extends through an opening defined in the vertical support member.

First claim

What is claimed is:

1. A free-standing workstation assembly comprising:
a frame including a top and a bottom;
a plurality of legs coupled with a bottom portion of the frame, the plurality of legs having a stowed configuration and an extended configuration; and
at least one height adjustable device secured to the frame, the at least one height adjustable device including:
a worksurface; and
a counterbalance mechanism configured to support the worksurface through a range of travel between the top and the bottom of the frame,
wherein the worksurface is configured to pivot between a stowed configuration and an extended configuration, the worksurface having a vertical position in the stowed configuration and a horizontal position in the extended configuration.

2. The free-standing workstation assembly of claim 1 , wherein the frame defines a plurality of recesses, wherein the plurality of legs are stored in corresponding recesses when in their stowed configuration.

3. The free-standing workstation assembly of claim 2 , wherein the plurality of legs rotate downward from their stowed position to their extended configuration.

4. The free-standing workstation assembly of claim 1 , wherein the plurality of legs extend along the bottom of the frame when in their stowed configuration, and wherein the plurality of legs rotate horizontally from their stowed position to their extended configuration.

5. The free-standing workstation assembly of claim 1 , wherein at least one of the plurality of legs includes a portion to overlap a side of the worksurface when the worksurface is in the stowed configuration to prevent moving the worksurface into its extended configuration before moving the plurality of legs into their extended configuration.

6. The free-standing workstation assembly of claim 1 , comprising:
a foot-actuated lever coupled with the frame, the foot-actuated lever configured to release the plurality of legs from their stowed position and lock the plurality of legs in their expanded configuration.

7. The free-standing workstation assembly of claim 1 , comprising:
at least one handle to assist in moving the free-standing workstation assembly.

8. The free-standing workstation assembly of claim 1 , wherein the frame defines at least one channel.

9. The free-standing workstation assembly of claim 8 , wherein the at least one channel is sized and arranged to store cables.

10. The free-standing workstation assembly of claim 8 , wherein the at least one channel is sized and arranged to mount accessories.

11. The free-standing workstation assembly of claim 8 , comprising:
a plurality of wheels coupled with the bottom of the frame.

12. The free-standing workstation assembly of claim 11 , wherein the plurality of legs includes a first set of legs coupled with a first side of the frame and a second set of legs coupled with a second side of the frame, wherein the first set of legs is configured to rotate in a first direction from the stowed configuration to the extended configuration and the second set of legs is configured to rotate in a second direction from the stowed configuration to the extended configuration, and wherein the second direction is opposite the first direction.

13. The free-standing workstation assembly of claim 12 , wherein the first direction is clockwise and the second direction is counter-clockwise.

14. The free-standing workstation assembly of claim 12 , wherein, from their extended configuration, the first and second sets of legs rotate horizontally inward toward a center of the frame and into their stowed position.
