Task oriented workstation with adjustable supports and variable assist pulley
First Claim
1. A workstation element comprising:
- a vertical column having a generally vertical track portion;
a car slidingly engagable with the vertical track portion, and having means for receiving a support arm; and
a motion arresting element pivotal relative to the car and having a track or column contacting portion whereby in a first mode, the coefficient of friction between the element and the track, column or track and column is insufficient to prevent bidirectional motion of the car relative to the track, and in a second mode, the coefficient of friction between the element and the track, column or track and column is sufficient to prevent at least unidirectional of the car relative to the track.

Abstract
A task-oriented workstation having a plurality of adjustable supports and work surfaces. The supports are linked to work surfaces as well as holders for workstation paraphernalia such as monitors and keyboards. In preferred embodiments, each support is preferably highly articulated, offering multiple degrees of freedom, i.e., translation and rotation about the several axes. A feature of a workstation embodiment is a variable assist pulley used to provide biased approximated linear bias to an object to be elevated. Another feature concerns the ability to easily modify the initial level of elevation bias provided to a track mounted support. Additional features of the workstation include car-mounted horizontal supports and constant angle horizontal surfaces.

9. A workstation element comprising:
-
a vertical column having a generally vertical track portion;
a car slidingly engagable with the vertical track portion, and having means for receiving a support arm;
a variable assist pulley having a drum, and a rotational bias element linked to the drum and a mechanical ground; and
a cable having a first end linked to the drum and a second end linked to the car whereby motion of the car imparts motion to the variable assist pulley and vice versa. - View Dependent Claims (10, 11, 12, 13)
