Snow thrower with an ergonomic handle
A snow thrower apparatus for removing snow from the ground. The snow thrower apparatus includes a snow thrower housing having a top wall, a rear wall and side walls. The snow thrower housing includes a rotatable snow throwing impeller assembly. A portion of the snow thrower housing forms a directional chute having a plurality of movable blades for throwing snow in a forward or sideward direction during operational use thereof. The directional chute includes a directional track having a control knob thereon to move the plurality of movable blades in a left or right direction. The snow thrower apparatus also includes an ergonomic handle connected to the snow thrower housing for pushing the snow thrower apparatus through the snow; and wheels detachably connected to the snow thrower housing for moving the snow thrower apparatus on the ground.
The present invention relates to a snow thrower with an ergonomic bent handle. More particularly, the snow thrower includes a directional chute having a plurality of movable blades for directing snow removal from the snow thrower to the left or right direction or the forward direction during operational use.
BACKGROUND OF THE INVENTIONSnow throwers, snow blowers, and snow removal apparatus are well known in the art. In the northern U.S. snow accumulation is quite common on the ground in relatively large amounts. It is necessary to clear the snow from sidewalks, driveways, paths and the like of homes, commercial buildings and industrial complexes. More particularly, snow removal is often required simply to have easy access to the user's home and to allow the user's car to be removed from the driveway.
Various types of snow removal machines, commonly referred to as snow blowers or snow throwers, have been developed and used in place of manual snow shoveling. These devices usually include a housing having some type of snow impelling mechanism, e.g. a rotatable rotor or auger. The mechanism throws or blows the snow outwardly from the housing to a point remote from the ground area being cleared. Many of the prior art snow blowers have been relatively heavy. Wheels or rollers have been attached to the housing to allow the snow blower to be rolled or steered over the ground. Some of these snow blowers were so heavy that these wheels were driven by a drive motor. However, these types of snow blowers were difficult to handle and steer, especially on a slippery surface such as snow. Users have been deterred from using them because of these problems. In addition, the complexity and weight of the snow blowers increases their costs rendering them uneconomical for users who do not have large areas of ground to be cleared of snow.
Small electrically operated snow throwers, and snow blowers have been developed to replace the more conventional manual shovels and the larger motorized snow blowers or snow throwers currently in use. This type of snow thrower is configured to act much like a shovel and is operated by the user in a manner similar to a shovel. This type of snow thrower has a small housing at one end of an elongated handle that extends upwardly from the housing. The housing includes a relatively open reel-type impeller and a small electric motor for rotating the impeller. A scraper bar is provided adjacent the bottom edge of the rear wall of the housing to allow the housing to bite into the snow. The rear wall of the housing also includes a guide section and an acuate portion which conforms to the periphery of the impeller. As the impeller rotates, the blades of the impeller contact and move the snow through the housing and eventually throw the snow up along the guide section of the rear wall to a position distally located from the snow thrower.
There remains a need for an improved snow thrower apparatus having a directional chute with a plurality of movable blades therein for directing the snow removal from the snow thrower to the left or right direction, as well as the forward direction during operational use. In addition, the snow thrower apparatus may include an ergonomic handle having a bent shaft for increased maneuverability for moving the snow thrower apparatus through the snow with a minimal physical effort by the user.
Accordingly, it is an object of the present invention to provide a snow thrower apparatus having an ergonomic handle having a bent shaft for increased maneuverability of moving the snow thrower through snow.
Another object of the present invention is to provide a snow thrower apparatus having a directional chute with a plurality of movable blades mounted in a directional track for throwing snow in a forward or sideward direction.
Another object of the present invention is to provide a snow thrower apparatus having a full-sized handle support assembly with an electrical plug outlet and ignition key compartment pad attached thereto.
Another object of the present invention is to provide a snow thrower apparatus having a heavy-duty plastic snow thrower housing that can withstand temperatures in the range of −30° C. to 66° C.
Another object of the present invention is to provide a snow thrower apparatus that is easily maintained, easy to clean and use and operates in a safe manner.
A further object of the present invention is to provide a snow thrower that can be mass produced in an automated and economical manner and is readily affordable by the user.
DESCRIPTION OF THE PRIOR ARTSnow throwers, snow blowers and snow removers having various designs, structures, configurations and materials of construction have been disclosed in the prior art. For example, U.S. Pat. No. 4,325,195 to COMBER discloses a snow thrower having an impeller with forward facing blades which extends a short distance inward from the periphery of the impeller. The snow thrower also includes a deflector vane assembly having a plurality of deflector vanes being laterally movable by a deflector plate. The deflector plate is also laterally movable with respect to the rear wall by means of a linkage assembly. The linkage pivots about a centrally-located point in order to deflect the plurality of deflector vanes to the right, center or left in order to permit a forward or sideward deflection of snow during snow throwing. This prior art patent does not disclose or teach the same structure, configuration and design of the plurality of movable blades for directing snow removal from the snow blower as in the present invention.
U.S. Pat. No. 6,163,986 to TOWNSEND discloses a non-motorized machine for throwing snow or other debris. The machine includes a frame supported by at least one wheel that activates at least one rotating blade or brush when the machine is pushed forward. The machine also includes a pivoting mechanism which allows an operator to direct the thrown snow/debris to either side by pivoting the blade or brush. The housing and blade pivot together as a unit. An adjustment lever and a pivot lock are provided to facilitate the pivoting action. This prior art patent does not disclose or teach the same structure, configuration and design of the plurality of movable blades for directing snow removal from the snow blower as in the present invention.
U.S. Pat. No. 4,295,285 to STEVENS discloses a snow thrower including a housing having rotatable impeller therein. The rotation of the impeller moves the snow through the housing and ejects the snow upwardly with sufficient force to throw the snow to a point distally located from the snow blower. This prior art patent does not disclose or teach the same structure, configuration and design of the snow blower of the present invention.
None of these prior art patents teach or disclose a snow thrower apparatus having an ergonomic handle and a directional chute with movable blades mounted in a directional track for throwing snow in a forward or sideward direction.
