Abstract

The invention provides illumination and may provide magnified viewing of an object using a means which may be located directly in front of a seated or reclining individual, while providing for the means to pivot out of the way for easy egress from the sitting or reclining position. The invention provides a counter weight at a fixed radius for stability, and to facilitate the user's easy assessment of whether the counterweight will contact or interfere with nearby objects. The use of the fixed radius counterweight provides utilities that are not achieved when using a variable radius counterweight, or a weighted base configuration.
