  "abstract": "A table, desk or wall-mount lamp is disclosed which is adjustable by being rotatable and also directable into several continuous directions for focusing the light onto an object and for focusing the intensity of light towards the object which is to be illuminated. The adjustability of the lamp is achieved by rotating parts of the lamp about three different axes and by sliding a portion of the lamp. One rotation is brought about by a tension wheel which is easily controllable.",
  "claims": [
    "1. A multidirectional task lamp comprising: a base; a mounting socket; a rod; a tension wheel having an axial opening and a peripheral cleat; a tubular extension arm including a socket end and a mounting end; a shaded socket portion; said mounting socket is disposed on said base; said rod rotatably extends between said mounting socket and said axial opening; said cleat includes an opening configured for slidably accepting said tubular extension arm; said tension wheel is rotatably connected to the rod via a cross bar associated with said rod; tension means associated with said tension wheel and another cross bar associated with said rod for controlling the rotatability of the tension wheel; said shaded socket portion is rotatably disposed on said socket end on said tubular extension arm; an electrical connection is guided through said tubular extension arm to provide an electrical connection to said socket end.",
    "2. The multidirectional task lamp of claim 1, wherein the base is suitable for wall mounting.",
    "3. The multidirectional task lamp of claim 1, wherein the tension wheel is a ring-shaped wheel having a V-shaped spoke extending between a center of said ring shaped wheel and a periphery thereat.",
    "4. The multidirectional task lamp of claim 3, wherein the tension wheel comprises a groove on the periphery of the tension wheel for avoiding slippage of the tension means.",
    "5. The multidirectional task lamp of claim 1, wherein the tension means comprises a wire.",
    "6. The multidirectional task lamp of claim 1, wherein the tension means comprises a flat band.",
    "7. The multidirectional task lamp of claim 1, wherein the tension means comprises an elastic band."
