     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular, to FIG. 1 thereof, the preferred embodiment of the new and improved adjustable portable utility light stand embodying the principles and concepts of the present invention and generally designated by the reference number 10 will be described. 
     Specifically, it will be noted in the various Figures that the device relates to a new and improved adjustable portable utility light stand for allowing the light to be closer to a working area. In its broadest context, the device consists of a hollow triangular base, a hollow trapezoid segment, a hollow middle segment, a hollow outer segment, a lamp segment, and a halogen lamp. 
     The device 10 contains a hollow triangular base 12 having a base piece 14 and two side pieces 16. The base piece 14 is longer than the two side pieces 16. The base piece 14 has two end portions and an intermediate extent therebetween. The two side pieces 16 each has a first end and a second end. Each first end is coupled with the two end portions of the base piece. Each second end is coupled together to form an apex 18. The apex 18 is truncated and is extended about 20 to 25&#34; from the base piece 14. The base piece 14 has an axle 20 disposed therein. The axle 20 extends outwardly of the two end portions. A pair of plastic wheels 22 are secured to the outwardly extending axle 20. The plastic wheels 22 allow the device 10 to be easily transported on the ground. The hollow triangular base 12 has a tube 24 having a first end and an open second end. The first end is secured to the apex 18 of the two side pieces 16. The open second end is secured to the underside of the base piece 14. The tube 24 bisects the hollow triangular base 12. An inner tube 26 is slidably secured within the tube. The inner tube 26 serves as a stabilizer bar. The stabilizer bar prevents the device 10 from falling over when incorporated in its variety of positions. 
     The device 10 contains a hollow trapezoid segment 28 having a lower portion 30, an upper portion 32, and two side portions 34. The lower portion 30 has two hinge tubes thereon. The two hinge tubes have a locking means therein. The two hinge tubes are pivotally secured to the base piece 14 of the hollow triangular base 12. The hinge tubes allow the trapezoid segment 28 to be folded into the triangular base 12 for storage or extended perpendicular to the triangular base 12 or to any point in between the two extremes. The upper portion 32 has two hooks 36 secured thereon serving as extension cord holders. An optional carrying handle can be incorporated into the device 10 by securing the handle to one of the two side portions 34. 
     The device 10 contains a hollow middle segment 38 having an upper portion 40, a lower portion 42, and two parallel side portions 44. The lower portion 42 has a hinge tube thereon. The upper portion 40 has a hinge tube thereon. Each hinge tube has a locking means therein. The hinge tube of the lower portion 42 is pivotally secured to the upper portion 32 of the hollow trapezoid segment 28 inward of the two hooks 36. The hinge tube of the lower portion 42 allows the middle segment 38 to be folded into the trapezoid segment 28 or to an extended position integral with the trapezoid segment 28. The upper portion 40 has two hooks 44 secured thereon outward of the hinge tube. 
     The device 10 contains a hollow outer segment 46 having an inner tube 48 and an outer tube 50. The outer tube 50 has a first end 52 and second end 54. The first end 52 has a short tube 56 secured thereto. The short tube 56 is pivotally secured to the hinge tube of the upper portion 40 of the hollow middle segment 38. This allowing the short tube 56 to be folded within the middle segment 38 or to an extended position integral with the middle segment 38 or any position between the two extremes. The second end 54 has a pull lock 58 secured thereto. The inner tube 48 has a first end 60, a second end 62, and an intermediate extent 64 therebetween. The first end 60 is telescopically secured within the outer tube 50. The intermediate extent 64 has a plurality of apertures 66 vertically aligned therein. The apertures 66 cooperate with the pull lock 58 of the outer tube 50 to selectively lock the inner tube 48 within the outer tube 50. The pull lock 58 allows the user to adjust the height of the inner tube 48 as it extends out of the outer tube 50. The second end 62 of the inner tube 48 has a screw lock 68 secured thereto. 
     The device 10 contains a lamp segment 70 having a first end 72 and a second end 74. The first end 72 is rotatably secured to the second end 62 of the inner tube 48 of the hollow outer segment 46 cooperating with the screw lock 68 thereof. The screw lock 68 of the inner tube 48 allows the user to position the lamp segment 70 at any angle desired. 
     A halogen lamp 76 is pivotally secured to the second end 74 of the lamp segment 70. The halogen lamp 76 can be pivoted up or down to better illuminate an area. The halogen lamp 76 is preferred over incandescent bulbs because they provide a much stronger illumination. 
     A second embodiment of the present invention is shown in FIG. 8 and FIG. 9 and includes substantially all of the components of the present invention further including a wall mounting bracket 78 having a first side and a second side. The first side is mountable on a wall. The second side removably receives the hollow triangular base 12. The wall mounting bracket 78 provides a means for securing the device 10 to a wall for a more permanent fixture, but the bracket 78 allows the device 10 to be easily removed for use in other areas. 
     People often have to work in dark areas where the lighting is inadequate or missing. They usually bring a portable electric light source into the area to provide enough light, but this often uses incandescent bulbs and/or is not sufficient. Portable lights can seldom be placed where they provide the best illumination, and are frequently housed in flimsy stands that are easily knocked over. The present invention is a better source of temporary illumination that overcomes these drawbacks. It uses one or two quartz halogen bulbs in reflector holders to provide bright light over a wide area. It folds up for storage, and extends up to 8&#39; at various angles. It can fit into a wall mount for use over a regular area, and if needed elsewhere can be lifted out and rolled on a pair of wheels. When unfolded it can be adjusted to different heights, extensions, and angles to get into and/or illuminate confined spaces. 
     The present invention consists of a base and three welded tubular segments that telescope or fold together for storage. All sections are permanently joined together by hinges made of inner and outer tubes. The base is triangular, with an axle on its longer side that is 32 inches to 36 inches long, including 2 inches on the ends for 71/2 inches plastic wheels. The other two sides are bent or truncated near their apex, and extend about 20 inches to 25 inches from the axle. A tube bisects the triangle, from the confluence of the sides to the underside of the axle. A smaller diameter tube that acts as a stabilizer bar slides inside the central tube, and a locking mechanism holds it in place, either extended or retracted. 
     A trapezoid that almost matches the base triangle in size and shape is the first segment. It is attached to the axle by two short hinge tubes which go around the axle and are welded to the base of the trapezoid so that they are just inside the sides of the base. They allow the trapezoid to fold flat on the base or be raised up 90 degrees or more. Each hinge tube has a screw-type locking mechanism that can lock the trapezoid in any position. An optional carrying handle may be attached to one side at the center. 
     The middle segment has a hinge tube surrounding the top of the trapezoid. Two parallel tubes that are almost as long as the stabilizer bar are welded to either end of the hinge tube and a screw lock is attached at its center on the opposite side. The electric cord may be wrapped around a pair of hooks on the outside of each tube. The upper end of each parallel tube has a short piece of tubing welded across it to act as the hinge tubes for the outer segment. These have screw locks in their middle. 
     The outer segment is composed of two telescoping tubes. The outer tube has a short tube welded across its inner end which fits into the hinge tubes on the ends of the middle segment, and a screw lock at the other end which can clamp the inner tube at any length to which it is extended. The inner tube also has a screw lock at its end which allows the lamp support tube to be rotated and fixed in any direction. The lamp support tube has a short segment welded perpendicularly to its center. Each end supports a lamp assembly which can be rotated up or down. 
     As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and the manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modification and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modification and equivalents may be resorted to, falling within the scope of the invention.
