Description

Snow sweeper

Technical Field

The present subject matter relates generally to snow plows, such as battery powered snow plows.

Background

Snow plows typically include a frame, for example, supported by wheels on which the frame can rotate. A handle may be attached to the frame for pushing and guiding the snow plow. The auger may be mounted within the housing to a motor that may rotate the auger. As the auger rotates, the auger may direct the snow to a chute attached to the frame. The chute can receive snow from the auger and direct (i.e., throw) the snow in a predetermined direction relative to the frame. Some snow plows include a chute that is movable between different positions relative to the frame such that in each position the chute throws snow received from the auger in a different predetermined direction relative to the frame.

Conventional snow plows face challenges. As an example, it may be difficult to attach or remove various features of the snowplow, such as the chute. In many cases, one or more tools are required for assembly/disassembly. Even a single tool may significantly impact the user experience. Furthermore, in some cases, difficulties in assembly/disassembly can result in the user accidentally damaging a portion of the snowplow.

Another challenge faced by some existing snow plows is the positioning of the chute (e.g., controlling the direction in which snow is directed from the chute). While some snow plows include a chute that is movable between different positions relative to the frame, such systems may require expensive motor assemblies or may otherwise be easily damaged.

While some snow plows have attempted to use batteries to power one or more features of the snow plow (e.g., an auger motor), this presents even more challenges. As an example, it is difficult to prevent the battery from being damaged, such as by snow or melted water. Snow plows can present challenges in terms of the fundamental nature of the environment they are intended to be in (e.g., surrounded by snow or water for extended periods of time). Furthermore, it can often be difficult to ensure a sufficient power supply without requiring a large or bulky battery.

Accordingly, it would be useful to provide a snowplow having features that address one or more of the challenges in the art, such as those discussed above.

Detailed Description

Reference now will be made in detail to embodiments of the invention, one or more examples of which are illustrated in the drawings. Each example is provided by way of explanation of the invention, not limitation of the invention. Indeed, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope thereof. For instance, features illustrated or described as part of one embodiment, can be used with another embodiment to yield a still further embodiment. It is therefore intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.

As used herein, 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 element from another, and are not intended to indicate the position or importance of each element.

Turning now to the drawings, and in particular fig. 1-3 and 9, exemplary aspects of a snowplow (e.g., snowplow 100) are illustrated. In general, the snowplow 100 includes a body frame 110 defining a vertical direction V, a lateral direction L, and a transverse direction T that are orthogonal to one another.

In some embodiments, one or more wheels 112 are rotatably attached to the fuselage frame 110 to support the fuselage frame 110 and generally allow the snowplow 100 to roll along the ground. A handle or handle frame 114 is attached to the body frame 110 (e.g., opposing wheels 112) for propelling and guiding the snowplow 100.

As shown, the snowplow 100 may define a discrete fuselage inlet 116 and fuselage outlet 118. For example, the body inlet 116 and the body outlet 118 may be defined in fluid communication between auger chambers 120 defined within the body frame 110. A fuselage entrance 116 may be defined in a forward portion of the fuselage frame 110 (e.g., upstream of the auger chamber 120) to receive snow, such as when the snowplow 100 is propelled forward. A fuselage exit 118 may be defined at the top of the fuselage frame 110 (e.g., downstream of the auger chamber 120 or upstream of the chute 122) to direct snow from the auger chamber 120.

In some embodiments, the body outlet 118 is positioned above the body inlet 116 or auger chamber 120 (e.g., in the vertical direction V). Additionally or alternatively, the fuselage exit 118 may be positioned rearward (e.g., in the lateral direction T) of the fuselage entry 116.

As shown, a chute 122 is attached to the fuselage airframe 110 to direct snow therefrom. For example, the chute 122 may be positioned generally downstream of the fuselage inlet 116 and the fuselage outlet 118. As will be described in greater detail below, the chute 122 may be rotatably attached such that the direction of snow from the snowplow 100 may be selectively selected or changed (e.g., by a user). Additionally or alternatively, the chute 122 may be removably attached such that the chute 122 may be selectively detached from the fuselage airframe 110 (e.g., without the use of any separate tools).

When assembled, the auger 124 is rotatably mounted within the fuselage frame 110 (e.g., rotated about the auger axis 128). For example, the auger 124 may be housed within the auger chamber 120. Additionally or alternatively, the auger 124 may extend along an auger axis 128 (e.g., parallel to the lateral direction L) between two sidewalls 126 of the auger chamber 120. In some embodiments, auger 124 or auger axis 128 is positioned below body outlet 118.

A motor 130 (e.g., a single speed motor or, alternatively, a variable speed motor) is mounted to (or enclosed within) the fuselage frame 110. When assembled, the motor 130 may be in mechanical communication with the auger 124. In some embodiments, drive assembly 132 couples (e.g., mechanically couples) auger 124 and motor 130. For example, a driven belt 134 may be disposed between the motor 130 and the auger 124. Additionally or alternatively, the drive pulley 136 and the driven pulley 138 may be disposed between the motor 130 and the auger 124 (e.g., secured to the motor 130 and the auger 124, respectively). In some such embodiments, the drive pulley 136 defines a diameter that is smaller than a diameter defined by the driven pulley 138. During use, the driven belt 134 may be looped around the drive pulley 136 and the driven pulley 138 to transfer rotational force from the motor 130 to the auger 124. An idler pulley 140 may be disposed between the drive pulley 136 and the driven pulley 138 in contact with the driven belt 134 (e.g., to keep the driven belt 134 taut).

Although the drive assembly 132 is shown between the auger 124 and the motor 130, it should be understood that alternative embodiments may include any suitable configuration for transferring motion from the motor 130 to the auger 124. As an example, the motor 130 may be coupled directly to the auger 124. As another example, a gear train having a plurality of gears may be engaged in mechanical communication between the motor 130 and the auger 124.

During use, as the motor 130 urges the auger 124 to rotate about the auger axis 128, snow may be generally urged (e.g., rearwardly) from the body inlet 116 and (e.g., upwardly) to the body outlet 118.

In some embodiments, the motor 130 further urges the snowplow 100 to move forward. For example, the auger 124 may be configured to contact the ground during use. Alternatively, the radial tip or edge of the auger 124 may be sized to extend beyond the bottommost portion of the fuselage frame 110. As the auger 124 rotates, friction between the auger 124 and the ground contact surface may generally push or propel the snowplow 100 forward. In additional or alternative embodiments, a separate secondary motor (not shown) may be mechanically coupled to the wheels 112 to urge the wheels to rotate independently of the motor 130 or auger 124.

In an alternative embodiment, the snowplow 100 is provided with a lighting assembly 144. For example, the lighting assembly 144 may be mounted to the fuselage frame 110. Additionally or alternatively, the lighting assembly 144 may be located above the fuselage entrance 116 and directed forward therefrom (e.g., to illuminate an area or region directly in front of the fuselage entrance 116). Generally, the lighting assembly 144 includes one or more suitable light sources (LEDs, halogen bulbs, fluorescent bulbs, etc.) to produce light emissions from these light sources. Furthermore, such a light source may be accommodated within a suitable ballast and at least partially covered by a suitable transparent or translucent cover.

In some embodiments, the controller 146 is disposed in operable communication (e.g., electrical communication) with one or more portions of the snowplow 100 to direct the features or operation of the snowplow. The controller 146 may include a memory (e.g., non-transitory memory) and one or more microprocessors, CPUs, etc., such as general or special purpose microprocessors that are operable to execute programming instructions or microcontrol code associated with the operation of the snowplow 100. The memory may represent a random access memory such as a DRAM or a read only memory such as a ROM or flash memory. In some embodiments, the processor executes programming instructions stored in the memory. For some embodiments, the instructions include a software package configured to operate the snowplow 100. The memory may be a separate component from the processor or may be included on-board the processor. Alternatively, the controller 146 may be constructed without the use of a microprocessor [ e.g., using a combination of discrete analog OR digital logic circuits such as switches, amplifiers, integrators, comparators, flip-flops, logic gates (e.g., AND, OR, XOR, NOT, NOR, NAND, etc.), etc. ] to perform control functions rather than relying on software.

The controller 146 or portions of the controller may be located at various locations throughout the snow plow 100. In an exemplary embodiment, the controller 146 is located within the fuselage airframe 110 (e.g., along with one or more suitable power sources or batteries 148 that provide current or voltage to the controller 146). In other embodiments, the controller 146 may be disposed at any suitable location within the snowplow 100. Input/output ("I/O") signals may be sent between the controller 146 and various operating components of the snowplow 100. For example, the motor 130, the lighting assembly 144, or one or more sensors may be in communication with the controller 146 via one or more signal lines or a shared communication bus.

One or more power sources or batteries 148 may be provided on the snow sweeper 100 to selectively power the motor 130, the lighting assembly 144, or other components of the snow sweeper 100 (e.g., in the form of direct current). For example, two or more batteries 148 may be received within the battery compartment 150. In some such embodiments, the snowplow 100 is configured to selectively operate in a single-battery mode and a dual-battery mode. For example, the controller 146 may be configured to alternately implement the cell mode and the dual battery mode based on whether one or two batteries 148 are detected. Alternatively, the batteries 148 may be selectively received in the battery compartment 150 in an electrical series or parallel connection. The controller 146 may detect the presence of the battery 148 based on the voltage received from the battery compartment 150 (or any other suitable method). In the single battery mode, only a single battery 148 (or a single battery including a minimum stored electrical energy threshold) is received within the battery compartment 150 and provides power to at least a portion of the snowplow 100 (e.g., the motor 130 or the lighting assembly 144). In the dual battery mode, two separate batteries 148 having a minimum threshold of stored electrical energy are received within the battery compartment 150 and mutually provide power to at least a portion of the snowplow 100 (e.g., the motor 130 or the lighting assembly 144). Thus, the controller 146 may automatically detect the presence of one battery or two batteries and select the appropriate mode accordingly.

In additional or alternative embodiments, the snowplow 100 is configured to support on-board charging of the battery 148 (e.g., within a battery compartment 150). For example, an extension cord or plug may be provided on the battery compartment 150 for connection to a suitable Alternating Current (AC) power source (e.g., a municipal power grid, a generator, etc.). When connected to an AC power source, the received AC current may be converted to Direct Current (DC) that is supplied to and stored in the batteries 148. In some such embodiments, the controller 146 includes a series charging circuit configured to sequentially charge at least two batteries 148 when connected to an AC power source. For example, the controller 146 may initially charge a first battery 148 within the battery compartment 150 and then charge a second battery 148 within the battery compartment 150. In some such embodiments, charging of the second battery 148 may begin only after (e.g., in response to) a predetermined maximum charge is established within the first battery 148. In other embodiments, charging of the second battery 148 is initiated after one or more predetermined intermediate thresholds (i.e., thresholds below a maximum charge) are established within the first battery 148. Additionally or alternatively, the charging of the first and second batteries 148 may be alternately initiated according to a predetermined sequence of steps. Optionally, the controller 146 may be further configured to prevent a normal discharge path (e.g., from both batteries 148) when connected to an AC power source. Therefore, at the time of charging, the operation of the motor 130 can be prevented.

As described above, the motor 130 may be a variable speed motor. Accordingly, the speed of the motor 130 (e.g., and thus the rotational speed of the auger 124) may be selectively varied. In some such embodiments, a speed selector input is provided to direct the rotational speed of the motor 130 or auger 124. For example, a speed selector input may be provided as a linear displacement switch 152 in operable communication with the motor 130. The linear displacement switch 152 may be configured to guide the rotational speed of the shift motor 130 according to the linear position of the linear displacement switch 152. Thus, as the longitudinal position of the linear displacement switch 152 changes (e.g., along the switch axis), the rotational speed of the motor 130 may also change. In an exemplary embodiment, the speed selector input is electrically coupled to the controller 146 or directly coupled between the motor 130 and a power source (e.g., the battery 148). The longitudinal position of the linear displacement switch 152 may be communicated (e.g., indirectly or indirectly) to the motor 130 as a speed signal from the linear displacement switch 152.

In some embodiments, the handle frame 114 generally extends from the fuselage frame 110 along a longitudinal axis 154. Specifically, the handle frame 114 extends longitudinally from a mounting end 156 to a gripping end 158. At the mounting end 156, the handle frame 114 is connected to the fuselage frame 110 (e.g., directly or through an intermediate mounting assembly, such as the handle corner assembly 160). Thus, the mounting end 156 is close to the fuselage housing 110. In contrast, the gripping end 158 is longitudinally spaced from the fuselage airframe 110. In other words, the gripping end 158 is distal from the fuselage frame 110 as compared to the mounting end 156. Note that while in the exemplary embodiment the handle frame 114 extends linearly along the longitudinal axis 154, other embodiments may provide a curvilinear extension between the handle frame 114 and the gripping end 158 while still extending generally along the defined longitudinal axis 154.

In certain embodiments, the grip 162 is disposed at the gripping end 158 of the handle frame 114. The grip 162 may provide a segment or defined area at which a user may grasp the handle frame 114 during use of the snowplow 100. For example, the grip 162 may extend laterally between the first end 164 and the second end 166. Optionally, separate lateral arms 184 may be provided at the first 164 and second 166 ends.

Turning particularly to fig. 4 and 5, various perspective views of the handle frame 114 (e.g., at the gripping end 158) are provided. As shown, the exemplary embodiment includes one or more

grip engaging paddles

168, 170 mounted on the grip 162. For example, a pair of

grip engaging paddles

168, 170 may be mounted on opposite lateral sides of the grip 162. As shown, the grip-engaging

paddles

168, 170 are movably mounted at the gripping end 158 and may be selectively engaged by a user's hand, for example, when gripping or otherwise contacting the grip 162. For example, the

grip engaging paddle

168 or 170 may extend laterally across at least a portion of the grip 162. During use, squeezing or pulling the

grip engaging paddle

168 or 170 toward the grip 162 may push the

grip engaging paddle

168 or 170 to an operating position, while releasing the

grip engaging paddle

168 or 170 may allow the

grip engaging paddle

168 or 170 to extend forward from the grip 162 to a non-operating position. In some such embodiments, the paddle spring 172 biases the

grip engaging paddle

168 or 170 to the non-operating position.

In certain embodiments, the

grip engaging paddle

168 or 170 extends (e.g., laterally) between the free end 174 and the pivot end 176. The pivot end 176 provides a mounting point for the

grip engaging paddle

168 or 170 to be secured to the grip 162, and a pivot axis about which the free end 174 pivots. In some such embodiments, the

grip engaging paddle

168 or 170 spans a centerline of the grip 162 (e.g., a lateral center point between the first end 164 and the second end 166). Specifically, the free end 174 may be located on one side of the centerline, while the pivot end 176 is located on the opposite side of the centerline. In some such embodiments, the pivot end 176 is closer to the second end 166 of the grip 162 than it is to the first end 164 of the grip 162, while the free end 174 is closer to the first end 164 of the grip 162 than it is to the second end 166 of the grip 162. If a pair of

grip engaging paddles

168 and 170 is provided, the second paddle 170 may have a pivot end 176 that is closer to the first end 164 of the grip 162 than to the second end 166 of the grip 162, while the free end 174 of the second paddle 170 is closer to the second end 166 of the grip 162 than it is to the first end 164 of the grip 162.

Advantageously, the

grip engaging paddle

168 or 170 may simulate linear motion (i.e., non-pivoting motion) while providing a relatively simple mounting configuration.

Optionally, the interface panel 178 may be located on the grip 162 (e.g., on or across a centerline between the first end 164 and the second end 166). The interface panel 178 may include one or more inputs (e.g., touch buttons, knobs, toggle switches, or capacitive touch panels) in operable communication with the controller 146. In some embodiments, both the first paddle 168 and the second paddle 170 extend (e.g., laterally in a cross pattern, as shown in fig. 5) through the interface panel 178.

In an exemplary embodiment, the

grip engaging paddles

168, 170 enable a safe condition. As an example, activation of the motor 130 or rotation of the auger 124 may be conditioned upon one or both of the

grip engaging paddles

168, 170 being actuated (e.g., gripped) or otherwise moved to an operating position. In some such embodiments, the controller 146 is configured to receive a user-initiated start signal (e.g., from an input on the interface panel 178) and a paddle signal (e.g., from grasping one or more of the engagement paddles 168, 170, or a switch mechanically coupled thereto), and then transmit an activation signal to the motor 130 and start rotation of the auger 124. The controller 146 may be further configured to require continuous receipt of the paddle signal while the motor 130 remains active. Loss of the paddle signal may cause the controller 146 to stop activation of the motor 130 (i.e., deactivate the motor 130) or rotation of the auger 124. Thus, releasing one or both of the grip engaging paddles 168, 170 (e.g., such that both

paddles

168 and 170 are in a non-operational position) may cause the auger 124 to be deactivated.

Alternatively, the paddle signal may be provided in the form of an open signal path. For example, the transmission of the paddle signal may be embodied as closing an electrical path (e.g., to/from the controller 146). The loss of the paddle signal may then be embodied as opening the electrical path. Thus, upon release of one or both of the

grip engaging paddles

168, 170, deactivation of the motor 130 may be virtually instantaneous.

As particularly shown in fig. 6-8, the handle frame 114 may include a telescoping assembly 180. In some embodiments, the telescoping assembly 180 includes a telescoping tube 182 into which another portion of the handle frame 114 (e.g., a receiving tube 186) can slide. For example, the lateral arms 184 of the handle frame 114 may include corresponding telescoping tubes 182 that receive another portion of the lateral arms 184 (e.g., receiving tubes 186) to selectively vary the overall longitudinal length between the gripping end 158 and the mounting end 156 of the handle frame 114.

In an alternative embodiment, a telescoping lock 188 may be provided with the telescoping assembly 180. When assembled, the telescoping lock 188 may selectively secure or lock the handle frame 114 over a particular or selected overall longitudinal length. In some such embodiments, a telescoping shield 190 is mounted to the telescoping tube 182 to secure the telescoping lock 188 thereto. The telescoping shield 190 may allow the telescoping lock 188 to rotate (e.g., about an axis perpendicular to the longitudinal axis 154) on the telescoping shield 190. The inner prongs 192 may extend inwardly from the telescoping lock 188 toward the telescoping tube 182. Rotation of the telescoping lock 188 may change the extension of the inner prong 192, thereby moving the inner prong 192 closer to or away from the longitudinal axis 154 (e.g., depending on the direction of rotation). A lock hole or opening 194 can be defined through the outer wall of the telescoping tube 182 to receive the inner prong 192. In turn, the inner prong 192 of the telescoping lock 188 may be permitted to selectively engage the receiving tube 186, for example, within the telescoping tube 182 (e.g., to limit further longitudinal movement of the receiving tube 186 relative to the telescoping tube 182). As an example, one or more grooves or openings may be defined through the receiving tube 186 (e.g., perpendicular to the longitudinal axis 154) to receive the internal prongs 192 and thereby define a predetermined setting of the total distance between the gripping end 158 and the mounting end 156 of the handle frame 114.

Turning now to fig. 9-13, various views of the snowplow 100, and in particular the handle angle assembly 160 of the handle frame 114, are provided. As shown, the handle corner assembly 160 includes an upper section 196 (e.g., as or as part of the telescoping tube 182) and a lower section 198 (e.g., mounted or secured to the fuselage frame 110). In some such embodiments, a segment collar 200 attaches the upper segment 196 and the lower segment 198.

When assembled, the handle corner assembly 160 generally allows a user to selectively set or change the angle of the handle frame 114 relative to the fuselage frame 110. In certain embodiments, the segment collar 200 defines a lateral handle axis 202 (e.g., parallel to the lateral direction L or the auger axis 128) about which the upper segment 196 is rotatable relative to the lower segment 198 or the fuselage frame 110. As shown in fig. 9, some embodiments provide multiple unique attachment locations of the handle frame 114 on the body frame 110. For example, along with an attachment use position (indicated in UP), one or more attachment stowed positions may be provided, such as an attachment forward position (indicated in dashed lines with FP).

In the exemplary embodiment, segment collar 200 includes a handle cup 206 mounted or secured to upper segment 196 and a base cup 208 mounted or secured to lower segment 198. Thus, the handle cup 206 may rotate with the upper section 196 relative to the base cup 208 and the lower section 198. For example, the handle cup 206 may selectively or alternately engage the base cup 208 (e.g., to prevent rotation relative to the base cup 208) and disengage the base cup 208 (e.g., to allow rotation relative to the base cup 208). Optionally, a cup shield 210 may be disposed in the handle corner assembly 160 (e.g., on the upper or lower segments 196, 198) and cover or enclose at least a portion of the segment collar 200 (e.g., the handle cup 206 or the base cup 208).

A pair of lateral interface teeth 212, 214 between the base cup 208 and the handle cup 206 may define a plurality of predetermined pivotal positions of the handle frame 114. For example, the plurality of teeth 214 defined on the base cup 208 may extend laterally toward the upper section 196, while the plurality of teeth 212 defined on the handle cup 206 may extend laterally toward the base cup 208.

During use of the snow plow 100, the pair of lateral interface teeth 212, 214 may be engaged such that relative rotation is prevented. However, during angular adjustment, the pair of lateral interface teeth 212, 214 may be laterally separated such that the handle cup 206 is allowed to rotate about the lateral handle axis 202 and relative to the base cup 208.

In some embodiments, the bracket clip 216 selectively clasps the base cup 208 and the handle cup 206 (e.g., such that the base cup 208 and the handle cup 206 are held together and the pair of lateral interface teeth 212, 214 are engaged). The bracket clip 216 may include a clip pin 218 that extends (e.g., laterally) through the segment collar 200 (e.g., through the handle cup 206 or the base cup 208 along the direction-finding handle axis 202). Additionally or alternatively, the clamp pin 218 may extend through the upper and lower segments 196, 198 (e.g., along the lateral handle axis 202).

On one lateral end of the clamp pin 218, a cam latch 220 may be provided. On the other lateral end of the clamp pin 218, a retaining flange 222 may be provided. Thus, the handle cup 206 and the base cup 208 may be sandwiched (e.g., laterally) between the cam latch 220 and the retention flange 222. When assembled, the cam latch 220 can be selectively pivoted (e.g., perpendicular to the lateral handle axis 202) between a clasped position (e.g., as shown in fig. 10) and a released position (not shown). In the clasped position, the eccentric lobe surface of the cam latch 220 may remain against the handle cup 206 (e.g., the cradle of the handle cup) and push the handle cup 206 and the base cup 208 together. In the released position, the eccentric lobe surface of the cam latch 220 may remain away from the handle cup 206, allowing lateral separation between the handle cup 206 and the base cup 208. Optionally, a clip spring 224 may be positioned in biasing engagement about the clip pin 218 to provide a separating force between the handle cup 206 and the base cup 208 (or between the upper section 196 and the lower section 198).

Optionally, a plurality of handle corner assemblies 160 may be provided on the handle frame 114. For example, as shown, a separate handle corner assembly 160 may be provided on each lateral side or arm 184 of the handle frame 114.

Turning now particularly to fig. 1 and 14-18 and 28, in some embodiments, the snowplow 100 includes a rotatable chute assembly 226 for selectively rotating the chute 122 about a chute axis 228. For example, the position or rotation of the chute 122 may be based on the relative position of the handle 236. In the exemplary embodiment, rotatable chute assembly 226 includes an actuator assembly 230 and a gear assembly 232 in mechanical communication with each other, such as through a tension line 234.

Generally, rotation of a portion of the actuator assembly 230 in a first direction (e.g., clockwise or counterclockwise about the grip axis 238) may pull the tension wire 234 and rotate the chute 122 in a corresponding first direction (e.g., clockwise or counterclockwise about the chute axis 228). Likewise, rotation of a portion of the actuator assembly 230 in a second direction (e.g., counterclockwise or clockwise about the grip axis 238) may pull the tension wire 234 and rotate the chute 122 in a corresponding second direction (e.g., counterclockwise or clockwise about the chute axis 228). For example, the handle 236 of the actuator assembly 230 may be in mechanical communication with the chute collar 204 on which the chute 122 is mounted. Optionally, mechanical communication may be provided between the handle 236 and the chute collar 204 via the tension line 234 and one or

more pulleys

242, 248. When the handle 236 is rotated clockwise/counterclockwise, corresponding movement at the collar 204 and chute 122 may therefore be achieved by the tensioning wire 234 or

pulleys

242, 248.

In the exemplary embodiment, handle 236 is attached to handle frame 114 (e.g., proximate to grip 162 or free end 174). For example, the handle 236 may be rotatably attached to the handle frame 114 for movement about a handle axis 238 (e.g., parallel to the lateral direction L or the auger axis 128). In some such embodiments, the handle 236 is rotatably secured to a handle bracket 240 secured to the lateral arm 184 of the handle frame 114.

When assembled, the handle 236 is in mechanical communication with an actuator pulley 242 (e.g., rotatably mounted to or enclosed within a handle bracket 240). As an example, one or

more gears

244, 246 may be disposed between the handle 236 and the actuator pulley 242 to direct or transfer rotational movement of the handle 236 to the actuator pulley 242. Alternatively, a pair of enlarged wire lobes may be provided on the tension wire 234 and secured within the actuator pulley 242, thereby fixing the relative positions of the tension wire 234 and the pulley 242. Additionally or alternatively, one or more wire springs 245 may be disposed along the tensioning wire 234. For example, a separate wire spring 245 may be provided at each end of the tensioning wire 234 (e.g., within the pulley 242). The engagement collar 247 can be urged against a corresponding end of the tension wire 234 (e.g., at a corresponding corner of the wire 234) by a corresponding wire spring 245. When assembled, each wire spring 245 may maintain tension (e.g., compressive tension) within the pulley 242 and provide a linear force on the wire 242, thereby adding tension to the wire 242 and advantageously tightening tolerances.

In some such embodiments, the handle gear 244 is fixed to the handle 236 (e.g., coaxial with the handle for rotation about the handle axis 238). Additionally or alternatively, the idler gear 246 may be fixed to (e.g., rotate with) the actuator pulley 242. As shown, the teeth of the handle gear 244 may mesh with the teeth of the intermediate gear 246 such that rotation of the handle gear 244 is transmitted to the intermediate gear 246, which in turn is transmitted to the actuator pulley 242. Alternatively, the diameter (e.g., root diameter) of the handle gear 244 may be larger than the corresponding diameter (e.g., root diameter) of the intermediate gear 246. When assembled, the gear ratio of the handle gear 244 to the intermediate gear 246 may be less than 1. In some embodiments, the gear ratio is greater than 0.1. Advantageously, a relatively large rotational movement of the handle 236 may be required to achieve a relatively small rotational movement of the actuator pulley 242 (e.g., thereby requiring the tension cable 234).

As shown, the tension line 234 may mechanically couple the actuator assembly 230 to the gear assembly 232 at the base pulley 248. Alternatively, a pair of enlarged wire lobes may be provided on the tension wire 234 and secured within the base pulley 248, thereby fixing the relative position of the tension wire 234 with respect to the pulley 248. The base gear 250 or the chute gear 252 may be disposed in mechanical communication with the base pulley 248 such that rotation of the base pulley 248 is generally transmitted to the chute 122 (e.g., at the collar 204 disposed about the chute axis 228).

In some embodiments, the base pulley 248 is fixed to (e.g., rotates with) the base gear 250. One or both of the base pulley 248 and the base gear 250 may be rotatably mounted within the fuselage frame 110. Further, when installed, the base gear 250 may be in mechanical communication with (e.g., meshed with) the chute gear 252.

In certain embodiments, the chute gear 252 is fixed to the chute collar 204 that supports the chute 122. For example, the chute gear 252 may be mounted to the chute collar 204 (e.g., via one or more mechanical fasteners, adhesives, etc.) and disposed about the chute axis 228 such that the chute collar 204 and the chute gear 252 may rotate together (e.g., with the chute 122) to change the rotational position of the chute 122. Movement of the tension line 234 (e.g., starting at the handle 236) may rotate the base pulley 248 and the base gear 250. Rotation at the base gear 250 may then be transferred to the chute gear 252, the collar 204, and the chute 122.

Referring to fig. 19-21, various views of the chute 122 are provided. In certain embodiments, as shown, the snowplow 100 may include a removable chute assembly. Advantageously, the chute 122 may be selectively removed or reattached to the fuselage airframe 110 without the use of tools, as would otherwise be typically required.

In some embodiments, the collar 204 is attached to the fuselage frame 110 around the fuselage exit 118. As described above, the collar 204 may be secured to the rotatable chute gear 252, or alternatively, directly to a portion of the fuselage airframe 110 (e.g., via one or more suitable mechanical fasteners, adhesives, etc.). In certain embodiments, the collar 204 is formed as a ring positioned coaxially with the fuselage exit 118.

In additional or alternative embodiments, the chute 122 is attached to the fuselage airframe 110, for example at the collar 204. When assembled, the chute 122 may be selectively rotatably engaged with the collar 204. Thus, the chute 122 can be selectively rotated relative to the collar 204 (e.g., about the chute axis 228 or vertical direction V) while resting on the collar. In an alternative embodiment, the chute 122 may include a base flange 256 that extends radially outward from a guide post 258 through which the snow is directed. As shown, the base flange 256 may rest on at least a portion of the collar 204. In some such embodiments, the base flange 256 generally extends about the chute axis 228, but defines one or more channels or cutouts. For example, tab channel 260 may be defined as a vertical gap extending along the circumferential length of base flange 256. As an additional or alternative example, the secondary channel 262 may be defined as a separate vertical gap that is spaced apart (e.g., circumferentially) from the tab channel 260 and extends along another circumferential length of the base flange 256. Alternatively, the circumferential length of the secondary channel 262 may be greater than the circumferential length of the tab channel 260.

As shown, the collar 204 may include resilient release tabs 264 at predetermined circumferential locations. For example, the resilient release tab 264 may be generally vertically biased and extend upward (e.g., toward the base flange 256). Optionally, a spring (e.g., a leaf spring) is formed with the collar 204 such that, for example, the resilient release tab 264, the spring formed with the tab 264, and the collar 204 are integral with one another (e.g., formed as a one-piece, unitary member). In certain embodiments, the resilient release tab 264 defines a shape or profile complementary to the tab channel 260. Additionally or alternatively, the resilient release tabs 264 may define a circumferential length that is approximately equal to or less than the circumferential length of the tab channel 260. Thus, when assembled, the resilient release tab 264 may extend (e.g., vertically) through and be received by the tab channel 260. As shown, the assembled position of the resilient release tabs 264 within the tab channel 260 may generally limit rotation of the base flange 256 and the chute 122 relative to the collar 204.

In additional or alternative embodiments, collar 204 may include secondary tabs 266 at predetermined circumferential locations (e.g., spaced apart from resilient release tabs 264). For example, the secondary tabs 266 may extend vertically in a rigid or fixed position relative to the rest of the collar 204. As shown, the secondary tabs 266 may define a circumferential length that is significantly shorter than the circumferential length of the secondary channel 262. Thus, when assembled, the secondary tab 266 may extend (e.g., vertically) through and be received by the secondary channel 262. Nonetheless, despite the resilient release tabs 264, the relatively short circumferential length of the secondary tabs 266 may allow the base flange 256 or chute 122 to rotate slightly (e.g., within a predetermined angular range of less than 90 °) relative to the collar 204.

In the exemplary embodiment, chute 122 further includes a plurality of radial tabs 270 that are circumferentially spaced below (e.g., from one another) base flange 256. In some such embodiments, a plurality of radial tabs 270 are all vertically spaced from the base flange 256. In particular, a vertical gap may be defined between the bottom surface of the base flange 256 and the top surface of the radial tabs 270. When assembled, the collar 204 may be positioned generally within the vertical gap. For example, at least a portion of the collar 204 may be selectively retained between the base flange 256 and the plurality of radial tabs 270 (e.g., such that vertical movement of the chute 122 relative to the collar 204 is limited). In some such embodiments, the collar 204 defines a plurality of inner slots 272 that generally correspond to and are complementary to the plurality of radial tabs 270.

During assembly or disassembly, the chute 122 may be rotated relative to the collar 204 such that the radial tabs 270 are vertically aligned with the inner slots 272 (e.g., such that the radial tabs 270 pass through the slots 272) prior to vertical movement relative to the collar 204. For example, attaching the chute 122 to the fuselage airframe 110 may require first vertically aligning the plurality of radial tabs 270 with the plurality of internal slots 272 and then further aligning the secondary tabs 266 with the secondary channels 262. The chute 122 may then be moved (e.g., downward) until the base flange 256 contacts the upper surface of the collar 204, or until the plurality of radial tabs 270 are completely below the collar 204. Once the tabs 270 are positioned below the collar 204, the chute 122 may be rotated relative to the collar 204 (e.g., about the chute axis 228) until the tab channel 260 is vertically aligned with the resilient release tab 264 or the secondary tab 266 contacts the end point of the secondary channel 262. When the resilient release tabs 264 and tab channels 260 are vertically aligned, the resilient release tabs 264 may spring upward into the tab channels 260, thereby limiting further rotation of the chute 122 relative to the collar 204.

Removing the chute 122 from the fuselage housing 110 may require pressing the resilient release tab 264 downward (or otherwise urging the resilient release tab 264 from the tab channel 260) and reversing the attachment steps.

Turning now to fig. 22-27, various views of portions of a battery compartment 150 for a snowplow 100 according to exemplary embodiments of the present disclosure are provided. As described above, certain embodiments of the snowplow 100 may include a battery bay 150 (e.g., at the rear 294 of the fuselage housing 110) to receive one or more batteries 148 therein.

As shown, the battery compartment 150 includes one or more interior walls (e.g., one or more side walls 274 and a bottom wall 276) that define a battery cavity 278. In some embodiments, the battery cavity 278 extends from the upper portion 280 to the lower portion 282. Additionally or alternatively, the upper portion 280 may define an opening 284 for the battery cavity 278 through which the battery 148 may pass (e.g., for inserting or removing the battery 148 out of the battery compartment 150). Thus, the battery cavity 278 may generally be described as a vertical cavity, however, as shown, the battery cavity 278 may extend at a slight angle (e.g., a non-parallel or non-orthogonal angle) with respect to the vertical direction V.

In the exemplary embodiment, battery bay 150 includes one or

more rims

286, 288 that extend around at least a portion of battery cavity 278. By way of example, the inner rim 286 may extend around the opening 284 of the battery cavity 278. Additionally or alternatively, the inner edge 286 may extend above (e.g., above the cell cavity 278). The vertical extent or maximum extent of the inner rim 286 may thus be higher than any batteries 148 received within the battery compartment 150. As an additional or alternative example, the outer rim 288 may extend around the opening 284 of the cell cavity 278. In some such embodiments, the outer edge 288 is radially spaced from the inner edge 286 such that a groove 290 is defined between the inner edge 286 and the outer edge 288 (e.g., radially outward from the cell cavity 278). Alternatively, the groove 290 may be sloped or inclined generally from the front portion 292 to the rear portion 294. During use, the groove 290 may capture or redirect fluid (e.g., liquid water between the inner edge 286 and the outer edge 288).

In a further embodiment, a hatch 296 is attached to the fuselage frame 110 to selectively cover the battery compartment 150. For example, the hatch 296 may be movable (e.g., rotatable) between an open position and a closed position. In the open position, the hatch 296 may be spaced apart from the battery cavity 278 and the opening 284, and may generally allow access to the battery cavity 278 (e.g., by a user). In contrast, in the closed position, the hatch 296 may extend across or span at least a portion of the opening 284 and may generally restrict access to the battery cavity 278. In an alternative embodiment, the hatch 296 includes an inner lip 298 that extends generally downward (e.g., toward the battery compartment 150 when in the closed position). Optionally, an inner lip 298 may extend around at least a portion of the opening 284.

In the closed position, the inner lip 298 may be received within the groove 290. For example, the inner lip 298 may rest on an upper surface of the groove 290 and radially separate the inner edge 286 from the outer edge 288. Advantageously, snow or liquid water on the hatch 296 may thus be directed to the groove 290 and away from the battery cavity 278.

Turning particularly to fig. 24-27, an exemplary embodiment of the battery compartment 150 includes a biased ejection assembly 300. Generally, the biasing ejection assembly 300 includes one or more springs 302 or load plates 304 (e.g., at the lower portion 282 of the battery compartment 150) to urge or bias the batteries 148 within the battery cavity 278 upward and away from the bottom wall 276. Locking the battery 148 in place within the battery cavity 278 (e.g., by moving the hatch 296 to a closed position or engaging the internal latch 306 within the battery compartment 150) may push downward and retain the biased ejection assembly 300. However, unlocking or releasing the battery 148 (e.g., by moving the hatch 296 to an open position or disengaging the internal latch 306) may allow the biased ejection assembly 300 to push the battery 148 upward (e.g., so that the user may advantageously and conveniently access the battery 148 above the locked position).

As shown in the exemplary embodiment of fig. 24, the biased ejection assembly 300 may include an aligned linear spring 302 (e.g., a compression spring, an air spring, a hydraulic spring, etc.) and a load plate 304 mounted within the battery compartment 150 for selective extension through a plate opening 308 defined in the bottom wall 276 of the battery compartment 150. Specifically, the spring 302 and load plate 304 may be linearly aligned with the plate opening 308. In some embodiments, a guide or support housing 310 is mounted below the battery cavity 278 and supports the linear spring 302 therein. Optionally, a plate flange 312 may extend radially from load plate 304 to selectively engage a bottom surface, such as bottom wall 276. In some such embodiments, the plate flange 312 extends beyond the plate opening 308 or generally defines a greater radial width than the plate opening 308. As the springs 302 urge the load plate 304 upward, vertical movement may be limited, for example, by contact between the bottom wall 276 and the plate flange 312.

As shown in the other exemplary embodiment of fig. 25, the biased ejection assembly 300 may include a pivoting load plate 304 and springs 302 (e.g., compression springs) and load plate 304 mounted within the battery compartment 150 to selectively drive one pivotable end (e.g., an inner end 316) of the load plate 304 through a plate opening 308 defined in the bottom wall 276 of the battery compartment 150. Specifically, the spring 302 and load plate 304 may be pivotally mounted below the battery compartment 150. The outer end 314 of the load plate 304 may be aligned with the spring 302, which biases the outer end 314 generally downward. Alternatively, the spring 302 may be mounted to a bottom surface of the bottom wall 276 (e.g., outside of the battery cavity 278). An inner end 316 of the load board 304 opposite the outer end 314 about the pivot point may be aligned with the board opening 308. As the spring 302 pushes the outer end 314 downward, the inner end 316 may be pushed upward (e.g., into engagement with the battery 148 within the battery cavity 278).

As shown in additional or alternative exemplary embodiments, the battery compartment 150 may define one or more latch slots 318. For example, the latch slot 318 may be defined through the sidewall 274 of the battery compartment 150. The latch slot 318 may receive a corresponding body latch 320 on the battery 148, which in turn may lock the corresponding battery 148 within the battery cavity 278 (e.g., against a biasing force provided from the biasing ejection assembly 300).
