(5) FIG. 4 is a representation of a rear view of the blade 22, wherein a switch 44, and a battery 46 are mounted to the shaft. The switch 22 can turn the present invention 10 on or off and can control the temperature of the heating element.

DETAILED DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION

(6) Referring now to the drawings, where the present invention is generally referred to with numeral 10, it can be observed that it basically includes a shovel assembly 20 and a heating assembly 40. It should be understood there are modifications and variations of the invention that are too numerous to be listed but that all fit within the scope of the invention. Also, singular words should be read as plural and vice versa and masculine as feminine and vice versa, where appropriate, and alternative embodiments do not necessarily imply that the two are mutually exclusive.

(7) Best shown in FIG. 2, the shovel assembly 20 includes a blade 22, a shaft 24 and a handle 26. In a particular embodiment, the shaft 24 may have an elongated cylindrical shape. The shaft 24 may be made of wood, aluminum or fiberglass. The handle 26 may be connected to a first distal end of the shaft 24. In one embodiment, the handle 26 may have a collar 26a with a first distal end that may be cylindrical where the shaft 24 may be received therein. A second distal end of the collar 26a may extend towards an axis parallel to a circular face of the first distal end. Thereby defining an oval shape. The second distal end of the collar 26a may be flat. Two vertical posts 26b can be located at a flat side of the distal end of the collar 26a with the oval shape. The vertical posts 26b can be placed on the vertical axis, next to the vertices of the flat side of the collar 26a. The vertical posts 26b can be connected to a horizontal member 26c, thereby defining the handle 26.

(8) In one embodiment, the blade 22 can be made of aluminum, copper, brass, steel, or any other metallic heat conductive material. In a preferred embodiment, the blade 22 may include a tip. The tip of the blade 22 may include a squared end. The blade 22 may include a lateral side perpendicular to the tip of the blade 22. The lateral side of the blade 22 may have the shape of an arc. Lateral sides of the blade 22 may include a laminar portion. The laminar portion of the blade 22 may extend from the tip of the blade 22 to an edge of a step 22a. The step 22a may be located at a distal end opposite to the tip of the blade 22. The step 22a may also include a laminar portion. The laminar portion of the step 22a may extend perpendicularly to the blade towards an interior of the blade 22. The blade 22 may have ridges 22b disposed on the interior of the blade 22 as it can be best observed in FIG. 3. The ridges 22b are disposed from a center of the step 22a to the tip of the blade 22. It may be suitable for the ridges 22b to be arranged in a sinusoidal pattern. The blade 22 may include a blade collar 25, the blade collar 25 may be perpendicularly located in the center of the laminar portion of the step 22a. The blade collar 25 may be cylindrical. The blade collar 25 may include an extended portion that extends at a rear portion of the blade collar 25 towards the direction of the blade collar 25. The blade collar 25 may receive a bottom distal end of the shaft 24 therein.

(9) Best observed in FIG. 4, the heating assembly 40 includes a switch 44 and a battery 46. The battery 46 may be rechargeable. In one embodiment the switch 44 and the battery 46 may be attached to the extended portion of the blade collar 25. The switch 44 may turn on or off the electrically heated snow shovel 10. When a user selects the switch 44 as off, the switch 44 opens the connection from the battery 46 to the heating element 42. Therefore the heating element 42 loses power when the present invention 10 is turned off. When the user selects the switch 44 as on, then the battery 46 can power the heating element 42 and the heating element 42 may be heated up. The heating assembly 40 may include a gauge 44a attached to the extended portion of the blade collar 25. The gauge 44a may measure the temperature of the heating element 42. The gauge 44a may include a display to communicate the temperature selected to a user. The temperature of the heating element 42 may be selected by a user via programmable buttons located on the gauge 44a. The programmable buttons may allow a user to select a desired temperature for the heating element 42.

(10) Referring to FIG. 3, the heating element 42 may be embedded on the ridges 22b and on the tip of the blade 22. The heating element 42 can be made of an electrical resistor or any other material that is capable of converting electric energy into heat. The heating element 42 may convert the power provided by the battery 46 into heat. The heating element 42 may heat up the blade 22. The hot blade 22 may melt snow.

(11) The foregoing description conveys the best understanding of the objectives and advantages of the present invention. Different embodiments may be made of the inventive concept of this invention. It is to be understood that all matter disclosed herein is to be interpreted merely as illustrative, and not in a limiting sense.
