Definitions
- the present subject matter relates generally to snow shovels, and more particularly to motorized snow shovels which include rotatable augers.
- Snow shovels are widely utilized to move snow and other environmental debris. For example, a common use of a snow shovel is to remove snow from a driveway and/or sidewalk. However, most known snow shovels are purely manual tools requiring manual labor during use. In some situations, such manual labor can be detrimental or dangerous, such as in the case of the elderly or those with health conditions.
- snow blowers can be expensive and complicated to operate, and generally blow snow into the air during operation. If there is a breeze during operation of the snow blower, the snow can be blown into unintended locations, including for example into the user.
- a motorized snow shovel in accordance with one embodiment, includes a shaft assembly extending along a longitudinal axis between a first end and a second end.
- the motorized snow shovel further includes a handle assembly connected to the first end, the handle assembly including a first handle.
- the motorized snow shovel further includes a head assembly connected to the second end.
- the head assembly includes a shovel, an auger rotatably connected to the shovel, and a motor operational to rotate the auger.
- a motorized snow shovel in accordance with another embodiment, includes a shaft assembly extending along a longitudinal axis between a first end and a second end.
- the motorized snow shovel further includes a handle assembly connected to the first end, the handle assembly including a first handle, a battery, and a trigger.
- the motorized snow shovel further includes a second handle connected to the shaft assembly between the first end and the second end.
- the motorized snow shovel further includes a head assembly connected to the second end.
- the head assembly includes a shovel and an auger rotatably connected to the shovel, the auger rotatable about an auger axis, the auger axis transverse to the longitudinal axis.
- the head assembly further includes a motor operational to rotate the auger, the motor powered by the battery and operated by actuation of the trigger.
- the term "or” is generally intended to be inclusive (i.e., “A or B” is intended to mean “A or B or both”).
- the terms “first,” “second,” and “third” may be used interchangeably to distinguish one component from another and are not intended to signify location or importance of the individual components.
- the present disclosure is generally directed to motorized snow shovels 10.
- Motorized snow shovels 10 in accordance with the present disclosure advantageously reduce the required manual labor associated with removal of snow or other environmental debris, and are further relatively inexpensive and simple to utilize.
- a motorized snow shovel 10 includes a shaft assembly 20 which extends along a longitudinal axis 22 between a first end 24 and a second end 26.

- the lock assembly 44 may connect the second handle 40 to the sleeve 48.
- a motorized snow shovel 10 in accordance with the present disclosure further includes a head assembly 50.
- Head assembly 50 may be connected to the second end 26 of the shaft assembly 20, e.g. opposite the handle assembly 30.
- Head assembly 50 may include a shovel 52.
- the shovel 52 may, during operation generally be placed on the ground or another surface from which snow or other environmental debris needs to be removed.
- Shovel 52 may, for example, include a main body 54 which generally receives the snow and/or other environmental debris.
- Main body 54 may have a forward-facing surface 56 which has a rear portion 58 and a base portion 60, as shown.
- the rear portion 58 may have a generally arcuate cross-sectional profile, e.g. when viewed in a direction transverse to the longitudinal axis 22.
- the base portion 60 may have a generally linear cross-sectional profile, and thus be a generally planar surface.
- Main body 54 may further include a bottom surface 62 which generally contacts the ground or another surface during use.
- the base portion 60 may be angled relative to the bottom surface 62, such as when viewed in cross-section, e.g. in a direction transverse to the longitudinal axis 22.
- the forward-facing surface 56 may further include a lip 64.
- Lip 64 may extend from the base portion 60, and may for example, connect the base portion 60 and bottom surface 62.
- the lip 64 may be angled relative to the bottom surface 62, such as when viewed in cross-section, e.g. in a direction transverse to the longitudinal axis 22.
- the angle 65 of the lip 64 relative to the bottom surface 62 may be greater than the angle 61 of the base portion 60 relative to the bottom surface 62.
- the main body 54 may extend between a first side 66 and a second side 68 along an axis (which may be parallel with an auger axis as discussed herein) which is transverse to the longitudinal axis 22.
- a first side 66 of the main body 54 may generally define an open space which allows for snow and other environmental debris to exit the main body 54, as discussed herein.
- a sidewall 70 may border the main body 54, such as at the second side 68.
- Shovel 52 may further include an outer casing 72, which may for example include a rear casing portion 74 and a side casing portion 76.
- the rear casing portion 74 may, for example, generally cover a back side of the main body 54 (e.g. opposite the forward-facing surface 56). Rear casing portion 74 may thus be connected to the main body 54.
- the side casing portion 76 may, for example, generally cover a back side of the sidewall 70. Side casing portion 76 may thus be connected to the sidewall 70.
- Head assembly 50 may further include an auger 80.
- the auger 80 may be positioned generally proximate the shovel 52, and may for example be connected, such as rotatably connected, to the shovel 52.

- Rotational of the auger 80 may advantageously move snow and/or other environmental debris generally along the auger axis 82, such as from the second side 68 towards the first side 66.
- the snow and/or other environmental debris may thus exit the shovel 52 via the open space defined by the first side 66 due to the influence of the auger 80.
- snow and/or other environmental debris is advantageously not blown into the air, and shovel 10 does not include any fans, blowers, or other apparatus to facilitate such blowing action.
- Auger 80 may, for example, include a shaft 86 and a blade 88.
- Blade 88 may extend helically about, and be connected to, shaft 86.
- Shaft 86 may extend along the auger axis 82, and may be connected to the bracket 84 and extend through the sidewall 70.
- blade 88 may extend at a constant pitch along a length of the blade 88, thus advantageously facilitating the side removal of snow and/or other environmental debris as discussed herein.
- Rotation of the auger 80 may advantageously be motorized.
- head assembly 50 may further include a motor 90.
- Motor 90 may, for example, be electrically connected to trigger 34 and/or battery 36, as discussed herein.
- the motor 90 may be operational to rotate the auger 80, and may thus be operably connected to the auger 80 such that operation of the motor 90 causes rotation of the auger 80.
- motor 90 may be a brushed DC electric motor.
- motor 90 may be a brushless DC electric motor.
- other suitable motors 90, and in particular electric motors may be utilized.
- motor 90 may be housed in the outer casing 72.
