![]() To prevent the lower arm portion from pivoting past vertical in response to the biasing force of the biasing element, the elbow joint is provided with a suitably disposed pivot stop element. More specifically, the biasing element is adapted to continuously pivot the lower arm portion about the elbow joint until the appropriate, vertically extending orientation is achieved. In accordance with a first embodiment of the present invention, the lower and upper arm portions of the hand-arm configuration are maintained in a perpendicularly disposed relationship, with the lower arm portion and the attached, simulated hand, extending vertically upwards from a horizontally projecting upper arm portion.
