BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to motorcycle riders' accessories and more particularly to a portable body warming apparatus easily attachable between the motorcycle and a conventional upper torso garment worn by the rider.
2. Description of Related Art
A broad array of accessory equipment is readily available to the motorcycle-riding enthusiast. One aspect of these popular accessories is related to dealing with inclement weather, including rain and cold winds and temperatures. During riding periods of cold air temperatures, engine heat typically warms the lower torso of the rider; however, the upper torso being typically exposed more directly to oncoming cold air, is subject to greater degrees of air chill and requiring heavier upper torso garments.
Prior art teaches a number of environmental-modifying apparatus and equipment for transferring air of different temperatures from one location or equipment component to another or into equipment worn by a user. The following U.S. patents are examples of heat transfer equipment of this general nature:

The present invention provides an easily manufacturable, economical portable heat transfer system and method which will derive heated air from an area immediately behind the engine and between the legs of the rider and directed by a small blower included in the system upwardly through a flexible conduit and beneath an outer upper torso garment worn by the rider.
BRIEF SUMMARY OF THE INVENTION
This invention is directed to a portable heat transfer system and method of warmth. The system includes an air blower having an air inlet and an air outlet and being adapted to be positioned and secured behind the engine in an area of heated air build-up beneath a rider seat where heat as a byproduct of engine operation accumulates. The air blower is connectable to an electric power source of the motorcycle to operate the air blower. An elongated flexible air transfer conduit is connectable at one end thereof to the air outlet of the air blower while an air outlet nozzle is connected to another end of the conduit. The outlet nozzle is adapted in size and shape to be inserted and held beneath an upper torso garment worn by the rider whereby warmed air is drawn into the conduct from the area of heated air build-up by the air blower is discharged from the nozzle beneath the upper torso garment to warm the rider.
It is therefore an object of this invention to provide a portable heat transfer system for delivering warmed air beneath the outer upper torso garment being worn by a motorcycle rider.
Still another object of this invention is to provide a heating arrangement for motorcycle riders which derives heat from the motorcycle engine and accumulates and transfers this warm air for heating the upper torso of the motorcycle rider.
Yet another object of this invention is to provide an easily installable portable heat transfer system easily attachable to existing features of a motorcycle and is easily connectable electrically for operating the system's blower to one of the unused access switches or circuits of conventional motorcycles.
In accordance with these and other objects which will become apparent hereinafter, the instant invention will now be described with reference to the accompanying drawings.



BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWING(S)
FIG. 1 is a perspective view of a typical motorcycle with the invention installed therein.
FIG. 2 is a perspective view of the air blower attachable to the motorcycle behind the engine as seen in FIG. 1.
FIG. 3 is a perspective view of the entire portable heat transfer system of this invention.
FIG. 4 is an enlargement of the area of FIG. 1 directly behind the motor showing attachment of the air blower.
FIG. 5 is an enlarged perspective view of the system in full operation with respect to a motorcycle rider seated atop the motorcycle.



DETAILED DESCRIPTION OF THE INVENTION
Referring now to the drawings, the invention is there shown generally at numeral 10 in FIGS. 3 and 5 and includes a small 12- or 24-volt blower motor 12 and a flexible, preferably ribbed plastic conduit assembly 14. The blower 12 includes a side entry air intake 18 within a molded plastic housing 16 and further includes an elongated cylindrical discharge snout or air outlet 20.
The flexible conduit 14 is formed preferably of a length of ribbed plastic tubing 22 having ribs 24 extending along the entire length thereof to enhance flexibility and to resist crushing or crimping of the conduit 22 itself. One end of the flexible air transfer conduit 22 as best seen in FIG. 3 is attached over the tubular outlet 20 of the air blower 12 while the other end of the conduit 22 is connectable onto an air outlet nozzle 26 having a tapered or angularly oriented opening 28 thereof which is easily insertable beneath the upper torso garment into the position shown in FIG. 5 and described in more detail herebelow. The particular air blower utilized in conjunction with this invention is manufactured by Radio Shack, Inc., P/N 273-199.
As seen in FIG. 1, the conventional motorcycle A includes motor C mounted conventionally within the frame F of FIG. 4 and also includes a flat plate D attached to the frame F onto which the air blower 12 is preferably connected either adhesively or mechanically attached preferably in the orientation shown wherein the outlet tube 20 is laterally extending for ease of attachment of one end of the flexible conduit 22 as previously described.
The motorcycle A further includes a padded seat B and a fuel tank G which are in proximity to the environment shown at E in FIGS. 4 and 5 located immediately rearwardly of the motor C and typically between the legs of the user. It is in this area E that air heated by the engine C is collected and easily drawn into the air blower 12.
As best seen In FIG. 5, the rider will typically wear a wind and temperature resistant upper torso garment or jacket J, preferably leather which will prevent cold air from penetrating therethrough and also including a snug waistband H to prevent air from getting beneath the jacket J during riding of the motorcycle A. The air outlet nozzle 26, having the tapered or slanted opening 28, is preferably adapted to be easily slid beneath the lower hem H of the jacket J into the position shown in hidden lines so that air collected into the air inlet portion 18 and delivered for discharge beneath the jacket J through the air outlet nozzle 26 is easily insertable into the position shown in hidden lines in FIG. 5 and is retained there by the relatively tight or snug fitting hem H which further is enhanced in its ability to retain this orientation by the ribs of the flexible conduit 22.
Note that the wiring 32 of the air blower 12 has a connector (not shown) which will easily interconnect with a typically available unused access switch of the motorcycle's electrical wiring system. Note further that, in situations where no flat support panel is available for direct attachment of the air blower thereto, the air blower may include an elongated flexible air intake conduit, the distal end of which is positioned just behind the engine. The air blower may then be mounted nearby, but not directly in the warm air region behind the engine.
While the instant invention has been shown and described herein in what are conceived to be the most practical and preferred embodiments, it is recognized that departures may be made therefrom within the scope of the invention, which is therefore not to be limited to the details disclosed herein, but is to be afforded the full scope of the claims so as to embrace any and all equivalent apparatus and articles.
