DETAILED DESCRIPTION OF THE EMBODIMENT

Detailed reference will now be made to the preferred embodiment of the present invention, examples of which are illustrated in FIGS. 1-6. A snow and ice melting device 10 (hereinafter invention) includes a power generating means 11, a housing 12, a heater deck 13, a handle 14, a plurality of wheels 15, a pivoting arm 16, an automated winch assembly 17, controls 18, a blower 19, and a heating element 20.


The power generating means 11 consists of a portable electric generator that burns a hydrocarbon fuel via an internal combustion engine.


The power generating means 11 is contained within the housing 12. The housing 12 has a plurality of wheels 15 to provide mobility to the invention 10. The heater deck 13 (as depicted) include wheels 15 to assist in the movement of the invention 10.


The heater deck 13 contains the blower 19 and the heating element 20. The heating element 20 is suspended below the blower 19, such that air is forced down from the blower 19, across the heating element 20 where the heated air impacts the ground, and thus melts ice or snow contained thereon. The heater deck 13 includes an air inlet 19A that is positioned above the blower 19 and enables air to pass into the heater deck 13 and across the blower 19. The heating element 20 traverses horizontally across the interior of the heater deck 13, and the heating element 20 is suspended above the ground via a plurality of brackets 21 that attach at predetermined points along both the heating element 20 as well as the interior surface of the heater deck 13.


The heater deck 13 connects to the power generating means 11 or housing 12 via the pivoting arm 16. The pivoting arm 16 enables rotational movement of the heater deck 13 with respect to the housing 12. The heater deck 13 can be suspended above the ground or folded vertically and adjacent to the housing 12 when not in use. The pivoting arm 16 may include a pin 16A, which enables the heater deck 13 to detach from the power generating means 11 or housing 12.


The automated winch assembly 17 consists of a winch cable 17A and a motor (not depicted). The motor will let out or reel in the winch cable 17A in order to rotate the heater deck 13 to a desired position. The winch cable 17A has a clip 17B that connects to an eyelet 13A located on the heater deck 13. The clip 17B can be detached from the eyelet 13A should it be desirable to detach the heater deck 13 from the housing 11. A control(s) 18 are provided to operate the automated winch assembly 17.


Controls 18 are provided to operate the blower 19 and heating element 20, independently. A power line 20A connects the power generating means 11 to both the blower 19 and heating element 20.


Attached about a perimeter of the heater deck 13 is a plurality of metal plates 22. The metal plates 22 attach to the heater deck 13 via a plurality of bolts 22A. Referring to FIG. 5, the metal plates 22 can be adjusted up or down with respect to the heater deck 13 in order to provide a smaller gap between the heater deck 13 and the ground to be heated by the invention 10. The inclusion of the metal plates 22 improves the overall efficiency of the invention 10 by limiting the amount of heat that escapes from the sides of the heater deck 13.


With respect to the above description, it is to be realized that the optimum dimensional relationship for the various components of the invention 10, 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 invention 10.
