Abstract

An adjustable pneumatic desk having telescoping upper and lower bases for positioning a worksurface relative the floor. A spring biased locking mechanism sets the height of the desk via prong engagement of incrementally height adjustably spaced engagement slots.

Claims

1. A height adjustable desk comprising:

an upper base having a worksurface;

a lower base having a floor support;

a first portion of one of said bases telescopingly receiving a second portion of the other of said bases thereby adjusting the height of said worksurface relative to said floor support;

said second portion includes a pneumatic spring assembly coupled to said first portion, and further includes a plurality of wheels for bearing against said first portion during height transition;

a plurality of spaced engagement slots arranged at incremental heights on one of said portions; and

a locking mechanism on one of said portions includes a covered handle biased in a closed position and having one or more prongs for engaging said slots and locking said portions thereby setting a height of said worksurface relative to said floor support.

2. The height adjustable desk as defined in claim 1 wherein said lower base includes wheels.

3. The height adjustable desk as defined in claim 1 wherein said locking mechanism includes releasable prongs biased in an engaging position with said slots.
