Fishing rod with heated handle
BACKGROUND OF THE INVENTION 
     This invention is related to heated handles for fishing poles, and more particularly to such a handle having a metal tubular body for containing the burning fuel disposed in the handle in such a manner that an air space is formed between the body and the handle to prevent the handle from becoming uncomfortably heated. 
     Heated fishing pole handles are known in the prior art for cold weather fishing such as for ice fisherman. Usually such devices employ a dry stick of fuel which is ignited, inserted in the handle and which may burn for several hours. Examples of such handles are disclosed in U.S. Pat. No. 3,858,567, which issued Jan. 7, 1975, to Norman D. Slogaski, and U.S. Pat. No. 4,020,825, which issued May 3, 1977, to Federico Fusetti. 
     A problem with prior art handles is that they tend to become too hot for the user to hold for an extended period of time, and occasionally problems occur in providing sufficient ventilating holes in the handle for the burning fuel element. 
     SUMMARY OF THE INVENTION 
     The broad purpose of the present invention is to provide an improved heated handle for a fishing pole in which the handle has a series of ventilating openings along its length which communicate with an internal, elongated chamber. A tubular aluminium body is disposed in the chamber for holding the fuel stick. The tubular body has a lesser diameter than that of the chamber so as to form an air space about the tubular body extending along the chamber. A cap provides means for blocking the fuel-receiving opening in the end of the handle. 
     The preferred embodiment provides several special advantages such as permitting sufficient air to pass through the handle into the fuel chamber to maintain the fuel stick in a satisfactory burning condition without having a handle that is so hot that it is uncomfortable for the user to hold. 
     Still further objects and advantages of the invention will become readily apparent to those skilled in the art to which the invention pertains upon reference to the following detailed description. 
    
    
     DESCRIPTION OF THE DRAWING 
     The description refers to the accompanying drawing in which like reference characters refer to like parts throughout the several views, and in which: 
     FIG. 1 is a view of a heated fishing handle illustrated in the preferred embodiment of the invention; 
     FIG. 2 is a sectional view of the handle of FIG. 1; and 
     FIG. 3 is a perspective view of the aluminium body which supports the fuel stick. 
    
    
     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring to the drawing, FIG. 1 illustrates preferred, heated handle 10 adapted to be connected to conventional fishing rod 12 in the usual manner. Handle 10 preferably is formed of a plastic material, and as illustrated in FIG. 2, has an internal, elongated chamber 14. The handle has a plurality of ventilating opening means 16 preferably along both sides as well as the top of the handle communicating with chamber 14. The length of the internal chamber corresponds to the portion necessary to heat the hand of a user grasping the handle. 
     The opening means are each about 1/8 inch in diameter and provide ventilation for the chamber. 
     Aluminium tubular body 18 is disposed in chamber 14. The inner end of the handle is narrowed at 20 to seat the inner end of body 18. The opposite, outer end of the body is enlarged at 22 and seated in the handle to provide a fuel-receiving opening. The arrangement is such that a cylindrical air space 26 is formed along the body adjacent the chamber wall. The distance between the body and the wall provides an air space with a thickness of about 1/4 inch extending along the major length of the tubular wall. Preferably the wall thickness of the tubular body is about 0.015 inches. This thickness is relatively important since if it is too thick, the body will build-up too much heat, making the handle too hot. 
     The tube has a plurality of ventilating opening means 27 for permitting air to pass into the tube to supply oxygen to the burning fuel element. 
     One end of the tubular body is bent-up to form a tab 28 which defines means for locating the inner end of a conventional fuel stick 30, which is ignited to burn in the chamber to provide a source of heat. 
     Plastic cap 32 is snapped into opening 22 and has a handle 34 for removing the cap. A wire element 36 is carried on the inner end of the cap to provide means for preventing the burning fuel from contacting the cap. 
     Thus it is to be understood that I have described an improved heated handle for a fishing pole having an air space about the body which forms the burning chamber arranged to provide sufficient air to the fuel element without building-up heat so that the handle becomes uncomfortable for the user.
