Configurable multimount task lighting system
The present invention relates generally to lighting systems, and more particularly to a freely adjustable, exchangeable and configurable lighting system that can be reconfigured, mounted and positioned in multiple independent configurations to provide task lighting to illuminate a specific area. The present invention relates more specifically to a reconfigurable lighting system employing surface connection means, support means and adjustment means to enable a task lighting element to be mounted to any desired vertical or horizontal surface, fixture or edge thereof. The present invention also relates more specifically to a magnetically enabled coupling and adjustment means that enables a task lighting element to be positioned at a selected rotational or angular orientation by hand, yet maintain its position against the force of gravity. The present invention also relates more specifically to a magnetically enabled parallelogram positioning system that enables a task lighting element to be positioned at a selected distance, height or angular orientation by hand, yet maintain its position against the force of gravity.
1. A parallelogram positioning system for a modular lighting system comprising:
(a) a mounting element; wherein said mounting element is configured to be removably attachable to a surface; wherein said mounting element has a first proximate side configured to attach to a receptive surface and a second distal side; wherein said mounting element is selected from a mounting means capable of attaching to a flat horizontal surface, flat vertical surface, an edge or surface of an object selected from a cubicle wall, table, chair, computer monitor, display screen, keyboard, desk, pole and office equipment;
(b) a first coupling element, removably attachable to said second distal side of said mounting element; wherein said first coupling element has a first proximate side configured to removably attach to said mounting element and a second distal side configured to removably attach to a parallelogram positioning element;
(c) a parallelogram positioning element being a parallel configuration of two support elements;
wherein a first proximate end of at least one of said support elements is rotatably attached to a said mounting element; and
wherein a second distal end of at least one of said support elements is rotatably attached to said first coupling element;
wherein said support elements are constructed of a material or have an associated surface thereon that is strongly attracted to a magnetic force exhibited by a magnet;
(d) at least one or a plurality of magnetic elements; wherein said magnetic elements are either fixed in position with respect to one of said support elements or are configured to be linearly slidingly engageable with one of said support elements;
wherein said magnetic elements are positioned between said support elements so as to be physically in contact with both of said support elements simultaneously; wherein the magnetic attractive force exhibited by said magnetic elements is strong enough to retain and maintain the relative positions of the said two support elements in a parallel configuration with respect to one another;
wherein said magnetic attractive force can be overcome by the application of an external mechanical force exhibited by a human user to change the relative position of said two support elements with respect to one another;
(e) a second coupling element; wherein a first proximate side is connected to at least one distal end of at least one of said support elements; wherein the second distal side of said second coupling element is configured to be removably attachable to a light engine; (f) a light engine, removably attachable to said second coupling element;
wherein said magnetic elements are fixed in position with respect to one of said support elements;
wherein said two support elements are each rotatably attached at both of their proximate ends to said mounting element;
wherein said two support elements are rotatably attached at both of their distal ends to said coupling element; and
wherein said magnetic elements are each attached to only one or more of said support elements; and
wherein said magnetic elements are configured to be linearly slidingly engageable with the support element to which they are not attached; wherein said magnetic elements enable the distance between the said two support elements to vary as a function of the angle of said support elements as the support elements are moved with respect to a horizontal reference plane.
