Title: Illuminated cane

Description:
CROSS REFERENCE TO RELATED APPLICATION 
     This application is a national stage entry of PCT/EC2012/000018 filed Mar. 23, 2012, under the International Convention and claiming priority over Argentinean Patent Application No. 20110101123 filed Mar. 4, 2011. 
     TECHNICAL FIELD OF THE INVENTION 
     The following invention refers to a illuminated walking cane that works as an aid for people that either need a supplementary balancer due to health conditions, or just look for comfort purposes. In the first case, we include blind people, old people, convalescents, the injured, amputees, etc. In the second case, it could be used by mountaineers, pedestrians, etc. 
     BACKGROUND OF THE INVENTION 
     Generally speaking, and as it is known already, it is a serious problem for people that need a walking cane to walk (especially in metropolis and urban areas, and in roads and highways with lots of traffic), where they might be run over or experience a fall. 
     The expressed problem has led to think that the solution has to do with the supply of a illuminated walking cane, being illuminated throughout its length, thereby becoming a marker device of the presence of its holder to others. 
     We should start with the present state and previous art of the technique, by mentioning that the main goal of the invention is based on a illuminated walking cane”, provided with the means to achieve luminosity, which can be activated by its user. It contains sounds as well, responding to electric pulses, that are determined by their handler, keeping safe the physical integrity of the user and others, improving their lifestyle at a very low cost. 
     We can also point out the simplicity of usage of the device, which is mainly commanded by push-buttons for determining the effect achieved by the cane. 
     It will be clear the way in which these and others objectives and advantages of the invention are reached in practice, more clearly, referring to the detailed description that follows. We have some examples, in no way limiting, of the preferred developments of the invention, and also of the pictures that follow, in which: 
    
    
     
       BRIEF DESCRIPTION OF THE DRAWINGS 
         FIG. 1 , is a schematic view of the luminous cane in a protractile way of use. 
         FIG. 2 , is a schematic view of the cane itself, with all its components. 
         FIG. 3 , is a schematic view of the cane, particularly its handle. 
         FIG. 4 , is a schematic view in a withdrawn position. 
     
    
    
     DETAILED DESCRIPTION OF THE INVENTION 
     In all the figures, the same reference numbers indicate equal or corresponding elements. These are:
       1 . Walking Cane.     2 . Cane handle.     3 . Battery compartment.     4 . Battery.     5 . Closure cap of the compartment ( 3 ).     6 . Button power switch.     7 . Clip cord, or leather clasp for the hand of the user.     8 . Cane pole.     9 . Telescopic cylindrical trunks forming the cane ( 8 ).     10 . Power switch to command the discharge of the cylindrical trunks ( 9 ).     11 . Conductors.     12 . Electric bulbs.     13 . Rubber tap.     14 . User.   

     The cane pole component  8  is made of a conductor of light material. It could be translucent, carbon fiber, methacrylate, polycarbonate, optical fiber, glass, plastic, or any other material that conducts light or is transparent or translucid. Also, the cane pole  8  is hollow, so as to allow the placement of at least one luminous source. 
     The luminous source includes a lamp, light bulb, or electric resistance, fed by interchangeable batteries, activated by alternating or direct current, solar or other energy. Luminous diode LEDs could also be used. 
     The luminous device includes an electric circuit supply with energy, built in the inside of the cane, lengthways. Through a power switch, the energy is activated, so as to convey light in the inside and outside of the cane, as a means of luminosity, similar to little light bulbs or electric torches, for the sightless. 
     The hookup between lamps or bulbs and the battery is done through the conductors of electricity. One of them contains a power switch, that allows to open and close the circuit at will. 
     It is very important to highlight the fact that the pole cane is made by a series of extended tubular pieces that expand and shorten by fitting one another, in telescopic action. And that they also contain an automatic trigger mechanism through a power switch, so that the cane can be either retractile or protractile. 
     According to the above and illustrated information, it is easy to understand the advantages of practical order that the illuminated walking cane provides. This way, the claims that follow, cover the range of the invention. 
     Having described and determined the nature of the invention already, and the way in which it can be put into practice in its main idea, what follows is declared to be claimed as an invention and exclusive property:
