Patent ID: 7487944

Claim:
A support for selective positioning of a display device over a work surface comprising: an attachment clamp for connection with a work surface, said clamp connected to a knuckle, said knuckle rotatably connected to said clamp, said knuckle rotatable about a first axis of rotation for horizontal positioning of said display device, said knuckle including an elastomeric torsion spring assembly secured to a first end of at least one arm, said elastomeric torsion spring assembly including at least one elastomeric element for providing resistance to differential rotation of said at least one arm with respect to said knuckle in a vertical direction, a second end of said at least one arm constructed and arranged to support said display device, said elastomeric torsion spring assembly providing resistance in proportion to the extent of differential rotation of said at least one arm with respect to said knuckle, said at least one elastomeric element further providing sufficient resistance to the extent of differential rotation of said at least one arm with respect to said knuckle to maintain said at least one arm in another position vertically displaced from a first position, said elastomeric torsion spring assembly includes a hand operable lever rotatably attached to said elastomeric torsion spring assembly for controlling resistance provided to said at least one arm by said elastomeric torsion assembly, whereby rotation of said lever in a first direction reduces said resistance provided by said differential rotation of said at least one arm about said second axis of rotation, whereby rotation of said lever in a second direction increases said resistance provided by said differential rotation of said at least one arm about said second axis of rotation, a portion of said elastomeric torsion spring assembly includes an external spline for interlocking engagement with said hand operable lever and wherein said hand operable lever includes an internal spline for interlocking engagement with said external spline; whereby said lever may be pulled outwardly to disengage said splines, rotated to reposition said lever, and pushed inwardly to re-engage said splines.
