ABSTRACT:
The foot rest mechanism of the present invention comprises chair attachment means for attachment to the underside of a work chair seat, a foot rest actuating mechanism supported by the chair attachment means for guided forward and rearward movement in relation to the chair attachment means, a foot rest including a foot rest platform and at least two foot rest platform support arms each having a first and second end. The first end of the support arms is attached to the foot rest platform and the second ends of the support arms are attached to the foot rest actuating mechanism. The support arms moveably suspend the foot rest platform in relation to the chair seat. Pivot means pivotally connect the second ends of at least two foot rest platform support arms to the chair attachment means. Forward or rearward movement of the foot rest actuating mechanism forces the second ends of at least two support arms to pivot about the pivot means wherein small forward or rearward movements of the foot rest actuating mechanism correspond to large forward or rearward movements at the foot rest platform. The foot rest mechanism additionally typically comprises means to lock the foot rest actuating mechanism in a fixed forward or rearward position in relation to the chair attachment means. The foot rest mechanism additionally may comprise means to adjust the vertical position of the foot rest platform on the foot rest platform support arms. The foot rest actuating mechanism may include moving arm rests or hand grips, or a gas spring mechanism.
