DETAILED DESCRIPTION OF THE DRAWINGS

[0029] FIGS. 1 and 2 show the present heated fishing rod 10, having a proximal end 11 and a distal end 13. Fishing rod 10 comprises an elongated body 20 with one or more eyelets 30 extending outwardly from the elongated body. A handle 40 is disposed at the proximal end 11, and a battery 42 is disposed within handle 40. A fishing line 60 and reel 62 are also shown.

[0030] The present invention provides a novel way to prevent fishing line 60 from freezing to any of eyelets 30 or to the body of elongated rod 20, as follows.

[0031] A heating system or element 50 is in electrical contact with battery 42. As best seen in FIGS. 2 and 6, heating element 50 extends in a hollow bore through the center of elongated body 20 from near the handle 40 to distal end 11 of elongated body 20. In addition, heating element also extends back along the exterior of elongated body 20 towards proximal end 11 of elongated body 20. Thus, heating element 50 extends down the center of body 20 and also extends back along the outside of body 20. In some embodiments, heating element may be comprised of separate heating elements or wires connected together. In other embodiments, heating element 50 may be one continuous resistance wire.

[0032] Accordingly, as seen by arrows H in FIG. 6, when current from battery 42 passes through resistance wire 50, the portion of heating element 50A that extends in the hollow bore through the center of elongated body 20 heats elongated body 20 from the inside out, and similarly, the portion of heating element 50B that extends back along the exterior of elongated body 20 simultaneously heats elongated body 20 from the outside in.

[0033] Preferably, resistance wire 50 is made 80% from nickel and 20% from chromium. However, it is to be understood that other suitable materials may be used instead. Preferably, battery 42 applies a variable voltage, causing resistance wire 50 to reach a temperature of between 80 F to 180 F.

[0034] As best seen in FIG. 4, resistance wire 50 also extends around eyelet 30 using one of several different approaches. In accordance with the present system, the heating is more focused at the eyelets 30 than along the elongated body 20 of the fishing rod. As a result, the eyelets 30 reach a higher temperature than the elongated body of the fishing rod. As will be explained, this can be achieved by increasing the wrapping density of heating wire 50 around eyelet 30 or by increasing the voltage from the battery 42 to resister wire 50 travelling through the interior of eyelet 30.

[0035] Preferably, as seen in FIGS. 1 and 2, elongated body 20 tapers from a wider proximal end 11 to a narrow distal end 13. As a result, heating element 50 applies more heat at distal end 13 as compared to proximal end 11. Therefore, distal end 13 will reach a higher temperature than proximal end 11 of the fishing rod. This has the advantage of keeping the hottest part of the fishing rod farthest from the fisherman/woman. This both keeps the fisherman/woman safe, and ensures that the region near the eyelet 30 at the distal end 13 does not freeze.

[0036] As seen in FIGS. 3A and 3B, eyelet 30 preferably comprises a generally circular housing with a portion of the heating wire 50 passing therearound. In various approaches, resistance wire 50 may be disposed within inner chamber 32 and may either be wrapped once or many times around inner chamber 32 of eyelet 30.

[0037] Preferably, eyelet 30 is 3D printed with inner channel 32 therein. After eyelet 30 has been 3D printed, resistance wire 50 be inserted into inner channel 32. Alternatively, eyelet 30 may be 3D printed around heating wire 50 such that the heating element is embedded within the housing of eyelet 30. Preferably, the housing of eyelet 30 is made of a plastic filament with thermal conductivity greater than 100 k, where k=(Btu/(hr×degrees F.×ft)).

[0038] Preferably as well, elongated body 20 of the fishing rod can be made of fiberglass or graphene, acrylonitrile butadiene styrene, polylactic acid, thermal polyeurethane, or any combination of these materials. Alternatively, elongated body 20 may be 3D printed.

[0039] As seen in FIG. 5, handle 40 includes battery 42 therein. Preferably, battery 42 is rechargeable, and can be recharged by connecting a power source to USB port 44 or Micro USB port 45.

[0040] In those embodiments of the invention where the body 20 of the fishing rod is 3D printed, different sections of the elongated body can be 3D printed to have different stiffnesses. As a result, these different sections can be made to have different flexibilities, such that sections near distal end 13 are more flexible.

[0041] Also, in those embodiments of the invention where the body 20 of the fishing rod is 3D printed, the eyelet 30 can be formed from powdered metal filaments that are 3D printed into and onto the 3D printed elongated body. Examples of powdered metal filaments include copper, bronze and steel.

[0042] In one optional embodiment of the invention illustrated in FIGS. 7A and 7B, the heating element 50 is one single continuous resistance wire having a first portion 50A that extends down the center of the elongated body 20 and a second portion 50B that extends back along the exterior of elongated body 20. As seen in FIG. 7A, portion 50B wraps around the elongated body in a spiral pattern. This same continuous wire can also have a third portion that is wrapped around eyelet 30 as seen in FIG. 7B. In accordance with one aspect of the invention, the amount of heating applied at the eyelets 30 (FIG. 7B) can be higher than the amount of heating applied along body 20 (FIG. 7A). This result can optionally be achieved by having a higher wrapping density of resistance wire 50 around the eyelet 30 than around the exterior of elongated body 20. (As understood herein, wrapping density may be understood to mean the number of wraps of resistance wire per square inch).

[0043] FIG. 8 illustrates that the hottest regions of the present system are within eyelet 30 since the heat from resistance wire 50 is focused at this location. The added darkening of the illustration immediately adjacent to eyelet 30 shows the area where heating is greatest and temperatures are highest.

[0044] In other optional aspects, the present fishing rod 10 further comprises a coating around the portion of heating element 50B that extends back along the exterior of elongated body 20. Thus, the coating may operate to distribute heat from resistance element 50 to insulate the exterior of the elongated body 20. Optionally, the coating can comprise a carbon-fiber epoxy. In an alternate embodiment of the invention in FIGS. 9A and 9B, a water transfer printing hydrophobic sheet 100 may be used. Specifically, rod 20 is simply dipped into hydrophobic sheet 100 in FIG. 9A such that the coating on hydrophobic sheet 100 is transferred to the exterior of rod 20 as seen in FIG. 9B.

[0045] Lastly, FIG. 10 shows the optional embodiment of the invention in which a display screen 120 displays either ambient conditions or operating conditions of the device, or both. For example, display 120 may interact with sensors on the fishing rod to show ambient temperature, atmospheric pressure, weather conditions, battery life, the temperature of rod 20 or eyelets 30, etc. In further optional embodiments, pressure sensors 122 may be included to determine if the 40 handle of the rod 20 is underwater. Should this occur, the system could use a Bluetooth connection to send a distress signal to other smartphones that are in the vicinity that are also connected via Bluetooth. Data and media transfer could also be provided by way of USB ports 44 and 45 to a microcomputer in handle 40.
