This work surface 21 is stable during adjustment and during use, even though the work surface 21 is cantilevered from the post 33a and columns 25a to provide clear knee room below the work surface 21. A link interconnects each of the motion converters to prevent unequal increments of the second motion in response to the first motions. 40 U.S. Pat. However, the shaft structure 44 prevents this relative displacement of the pinions 43a and 43b. 4,967,733 (Rousseau) discloses a scaffold-like lifting carriage comprising four corner posts, each having a gear rack, and a rectangular platform mounted between the corner posts. If an individual stands, he or she will be forced to stoop. A horizontal work table has a pair of spaced depending second supports that align with corresponding ones of the first supports. In this specific embodiment, the posts 33a and 33b telescope or nest in the columns 25a and 25b respectively. A gear and chain mechanism interconnects the first shaft with a parallel second shaft with spiral gear nuts. However, the post 33a can not move laterally in the column 25a. Gas springs hold up to 50 lbs. Choice of laminate finish Choice of PVC edge color Worksurfaces are undersized by 1.5" side-to-side, and.5" from front-to-back from stated dimensions to allow for height adjustment when adjacent to other surfaces or furniture A work table is cantilevered from posts supported for vertical motion inside columns from a base. The roller 60 extends along the shaft 61 over a length corresponding to the total length of the rollers 51 and 52 and intermediate pinion 43a. 4,944,366 discloses a scaffolding with a rectangular lower frame. So I could not base my designs off of any market item. You need a sturdy, quality piece of adjustable height office furniture that works for a lifetime. This height adjustment produces relative linear motion between the first and second supports that is converted to angular motion. U.S. Pat. The work table unit includes a planar horizontal table top 31 and a supporting open frame 32 below the table top 31. 62 Each upper sleeve portion has an opposite thread to engage a correspondingly threaded leg that depends from each corner of the upper frame. The height of a workbench used primarily in the standing position, even with keyboard work should be 1000mm above the floor.

In one posture, for example a sitting posture, the work table height will not be optimized for that person in any other posture. A rigid shaft interconnects two pinions and prevents relative pinion rotation. An Adjustable Surface is a sit-to-stand table solution that goes beyond added health benefits. More recently, such work tables have been constructed with a pedestal base that supports the table at a rear portion to cantilever the deck assembly forward from the base. Each requires a support at each corner to provide stability and to provide even movement while the work surface remains horizontal. In accordance with still another aspect of this invention, the height of a work table with respect to a supporting surface is adjusted by applying a displacement force between a base and a planar work surface at a position intermediate first and second supports.

However, none of these structures is particularly adapted for providing furniture with adjustable height work surfaces. The human body is not designed to thrive in a setting where it’s forced to sit all day. The Focus Adjustable Table $735. An article of furniture as recited in claim 1 wherein each said second support includes a post with a rear elongated channel formed therein and wherein each of said spaced guide means additionally comprises glides supported by said first supports for engaging said rear channel thereby to maintain the engagement of said rack and pinion during relative motion between said first support and post. 4 further depicts a shaft extension 44c that overlies and is fixed to the shaft 44a thereby to complete the shaft assembly 44. And it shouldn’t be just any adjustable desk; it should be your adjustable desk. In prior rack and pinion assembly driver, a pinion drives the rack to displace the load and must be sized accordingly.
