Abstract
An adjustable height work station is adjustable between a seated work level and a lifted work level. The work station includes a base structure, a work area, and a lift arm. The work area incorporates a substantially planar surface. The lift arm has a first end and a second end. The first end is pivotally secured to the base structure while the second end is pivotally secured to the work area. Tie first end and second end are pivotable through a range of motion to raise and lower the work area between the seated work level and the lifted work level while maintaining the planar surface of the work area in a substantially horizontal position through the range of motion.
Claims13
A body positioning system, comprising:
- a chair structure assembly containing a backrest and pressure-bearing surface couplably interconnected by a parallel linkage assembly, the parallel linkage assembly including a piston assembly coupled to the pressure-bearing surface and spaced laterally from the backrest;
- a knee-support assembly;
- and
- a support structure having a plurality of wheels for repositioning said support structure, wherein said support structure supports said chair structure and said knee-support assembly in a co-linear orientation, and, wherein the supported chair structure assembly, in combination with the supported knee-support assembly and support structure, is adjustable to provide a seated work position and a lifted work position while at all times maintaining a substantially perpendicular orientation of the back rest to the floor, and wherein the piston assembly is coupled to the support structure and is adapted to extend the parallel linkage assembly when the chair support assembly is in the lifted work position thereby placing the pressure bearing surface in a substantially co-planar relation with the back rest.
A body positioning system comprising:
- body support means for supporting the torso of a human user;
- knee support means for supporting the knees of a human user;
- means for supporting said body support means and said knee support means in a co-linear orientation, said means for supporting including rolling repositioning means for repositioning said body positioning system at a desired location, wherein said body support means, in combination with said knee support means, is positionable between a seated work position and a lifted work position, wherein said body support means has a back rest operably coupled via a parallel linkage to a seat, the parallel linkage assembly including a piston assembly coupled to the seat and spaced laterally from the back rest, said back rest maintaining a substantially perpendicular orientation to the floor throughout the range of body support positions between the seated work position and the lifted work position, wherein the piston assembly is coupled to the means for supporting said body support means and is adapted to extend the parallel linkage assembly when the body support means is in the lifted work position thereby placing the seat in a substantially co-planar relation with the back rest.
