WHEELED OSCILLATING BLADE DEVICE

A wheeled oscillating blade device for pushing an oscillating blade on wheels to facilitate removing materials from the ground surface includes a housing. A pair of wheels is rotatably coupled to the housing to facilitate pushing and pulling the housing on a ground surface. A motor is positioned within the housing, and a shaft extends out from the motor. The motor rotates the shaft in an oscillating motion when the motor is turned on. A blade mount is positioned within the bottom opening and is in mechanical communication with the shaft, wherein the shaft oscillates the blade mount when the motor is turned on. A blade is mounted to the blade mount, wherein the blade oscillates when the motor is turned on. The oscillating motion of the blade facilitates removing materials from the ground surface.

BACKGROUND OF THE INVENTION

(1) Field of the Invention

The disclosure relates to power tool and more particularly pertains to a new power tool for pushing an oscillating blade on wheels to facilitate removing materials from the ground surface.

The prior art relates to power tools and includes a variety of power tools oscillating a blade when the power tool is turned on. Known prior art does not include a power tool oscillating a blade and having a pair of wheels such that the blade is movable adjacent to a ground surface as the power tool is pushed forward on the wheels.

BRIEF SUMMARY OF THE INVENTION

An embodiment of the disclosure meets the needs presented above by generally comprising a housing including a bottom wall, a front wall, a back wall, a pair of side walls, and a top wall. The bottom wall has a bottom opening extending therethrough and into the housing. A pair of wheels is rotatably coupled to the housing and is configured to facilitate pushing and pulling the housing on a ground surface. A motor is positioned within the housing, and a shaft extends out from the motor. The motor rotates the shaft in an oscillating motion when the motor is turned on. A gear is coupled to the shaft of the motor. The gear is a toothed wheel, and the shaft extends through a center of the gear, wherein the gear is fixed to the shaft such that the gear oscillates when the motor is turned on. A blade mount is positioned within the bottom opening. A top surface of the blade mount is toothed, wherein the top surface is engaged with the gear such that the blade mount oscillates when the motor is turned on. A blade is mounted to the blade mount. A power supply is electrically coupled to the motor. A switch is electrically coupled to the motor and is engaged to turn on or off the motor. An elongated member extends outwardly from the housing. The elongated member has a first end and a second end, and the second end defines a grip for the elongated member, wherein the grip is configured to be grabbed by a user to push and pull the housing on the wheels.

DETAILED DESCRIPTION OF THE INVENTION

As best illustrated inFIGS.1through10, the wheeled oscillating blade device10generally comprises a housing12including a bottom wall14, a front wall16, a back wall18, a pair of side walls20, and a top wall22. The bottom wall14has a bottom opening24extending therethrough and into the housing12. The back wall18has a back opening26extending therethrough and into the housing12. A door28may be pivotally attached by a hinge30to a peripheral edge32of the back opening26such that the door28may be positioned to close the back opening26. The door28may have a latching member34to secure the door28in a closed position when the door28closes the back opening26. A pair of wheels36is rotatably coupled to the housing12and is configured to facilitate pushing and pulling the housing12on a ground surface38. Each of the wheels36are rotatably coupled to a respective one of the pair of side walls20. The pair of wheels36is positioned proximate to the back wall18and to the bottom wall14.

A motor40is positioned within the housing12, and a shaft42extends out from the motor40. The motor40rotates the shaft42in an oscillating motion when the motor40is turned on. The shaft42is positioned above the bottom opening24of the bottom wall14. A gear44is coupled to the shaft42of the motor40. The gear44is a toothed wheel, and the shaft42extends through a center of the gear44, wherein the gear44is fixed to the shaft42such that the gear44oscillates when the motor40is turned on.

A blade mount46is positioned within the bottom opening24. The blade mount46has a pair of lateral ends48. Each of the lateral ends48has a respective one of a pair of upper protrusions50and a respective one of a pair of lower protrusions51extending outwardly therefrom. Each of the lower protrusions51are positioned beneath the bottom wall14. The lower protrusions51elongate a bottom surface of the blade mount46. Each of the upper protrusions50are coupled onto the bottom wall14by a pair of rolling members52, wherein the pair of rolling members52slide the pair of upper protrusions50upon the bottom wall14when the motor40oscillates the blade mount46. A top surface of the blade mount46is toothed, wherein the top surface is engaged with the gear44such that the blade mount46oscillates when the motor40is turned on.

The bottom surface of the blade mount46has a pair of holes54extending therethrough. A blade56is mounted to the blade mount46. The blade56is a plate having an upper surface, a lower surface, and a front edge. The front edge is serrated to define a cutting edge58configured to saw through objects. The blade56has a pair of apertures60extending through the upper surface and the lower surface. Each of the apertures60has equal diameters with a respective one of the pair of holes54. The upper surface of the blade56abuts the bottom surface of the blade mount46and a middle axis62of each of the apertures60aligns with a center axis64of each of the holes54. A pair of bolts is inserted through a respective one of the pair of apertures60of the blade56and into a respective one of the pair of holes54the blade mount46to secure the blade56to the blade mount46. The blade56is removeable from the blade mount46so that an alternative blade66may be mounted to the blade mount46. A forward edge68of the alternative blade66is serrated and convexly arcuate to facilitate scraping adhesives from the ground surface38.

A power supply70is electrically coupled to the motor40. The power supply70is a replaceable battery, wherein the power supply70is removable from the housing12through the back opening26. The replaceable battery typically comprises a lithium battery. A switch72is electrically coupled to the motor40and is engaged to turn on or off the motor40. The switch72is mounted to the top wall22of the housing12. An elongated member74extends outwardly from the housing12. The elongated member74has a first end76and a second end78. The first end76is pivotally coupled to a juncture of the top wall22and the back wall18by a pivoting pin79. The second end78defines a grip80for the elongated member74, wherein the grip80is configured to be grabbed by a user to push and pull the housing12on the wheels36. The elongated member74is telescopic, wherein a length from the first end76to the second end78is adjustable. Alternatively, the switch72may be mounted to the grip80of the elongated member74, wherein the user may turn on and off the motor40when holding the grip80.

In use, the blade56is secured to the blade mount46with the pair of bolts62. The switch72is engaged to turn on the motor40so that the blade56begins to oscillate. The user grabs the grip80of the elongated member74and pushes the elongated member74forward such that the housing12and the blade56are pushed forward. The blade56may oscillate between a carpet82and the ground surface38to scrape away any adhesive holding the carpet82to the ground surface38as the blade56is pushed forward.
