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.
Claims15
A lamp comprising
- a stand member;
- a pivotable structure supported on said stand member and pivotable about a vertical axis;
- a counterweigth secured to said pivotable structure at a fixed distance from vertical axis and at a fixed elevation, and configured for rotation in unison with said pivotable structure;
- and
- a lamp structure carried by said pivotable structure, movable toward and away from said vertical axis, variably and pivotally extending in a radial direction, opposite the radial direction at which said counterweight is mounted, while said couterweight is secured at said fixed elevation.
A lamp comprising
- a supporting stand member;
- a pivotable structure secured to said stand member, and configured for pivotal movement about a substantially vertical axis;
- a counterweight rigidly mounted on said pivotable structure at a fixed distance from said vertical axis and at a fixed elevation, and
- a lamp structure mounted on said pivotable structure which rotates in unison with said counterweight about said vertical axis, said lamp structure variably extends in a radial direction, opposite the radial direction in which said counterweight extends, while said counterweight is secured at said fixed elevation.
A lamp comprising
- a stand member;
- a pivotable structure supported on said stand member and pivotable about a vertical axis;
- a counterweight supported on said pivotable structure and mounted at a fixed distance from said vertical axis and at a fixed elevation;
- a lamp structure carried by said pivotable structure, pivotable in unison with said counterweight about said vertical axis and pivotally extending in a radial direction, opposite the radial direction at which said counterweight is mounted, while said counterweight is at said fixed elevation
- said lamp structure being articulated to provide translational movement substantially in a plane passing through said vertical axis;
- and
- spring means provided in said articulated lamp structure for countering the weight of said articulated lamp structure.
