Description

SNOW THROWER

FIELD OF THE INVENTION

[0001] The present subject matter relates generally to snow throwers, such as battery-powered snow throwers.

BACKGROUND OF THE INVENTION

[0002] Snow throwers often include a frame supported, for instance, by wheels on which the frame can rotate. A handle may be attached to the frame for pushing and directing the snow thrower. An auger may be mounted within the frame to an engine that can rotate the auger. As the auger rotates, it may direct 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 throwers include chutes that are moveable between various 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.

[0003] Challenges exist with conventional snow throwers. As an example, it can be difficult to attach or remove various features of the snow thrower, such as the chute. In many instances, one or more tools are required for assembly/disassembly. Even the requirement of a single tool can significantly impair a user’s experience. Moreover, in some instances, difficulties in assembly/disassembly can lead a user accidentally damaging a part of the snow thrower.

[0004] Another challenge for some existing snow throwers is positioning of the chute (e.g., to control the direction in which snow is directed from the chute).

Although some snow throwers include chutes that are moveable between various positions relative to the frame, such systems can be require expensive motor assemblies or can otherwise be prone to damage.

[0005] Although some snow throwers have attempted to use batteries to power one or more features of the snow thrower (e.g., an auger motor), this can present even more challenges. As an example, it can be difficult to prevent battery damage, such as from snow or melted water. The very nature of the snow thrower’s intended environment (e.g., surrounded by snow or water for extended periods of time), creates challenges. Moreover, it can often be difficult to ensure an adequate power supply without requiring a large or cumbersome mass of batteries.

[0006] As a result, it would be useful to provide a snow thrower having features addressing one or more challenges in the field, such as the challenges identified above.

DETAILED DESCRIPTION

[0040] 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. In fact, 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 of the invention. For instance, features illustrated or described as part of one embodiment can be used with another embodiment to yield a still further

embodiment. Thus, it is intended that the present invention covers such modifications and variations as come within the scope of the appended claims and their equivalents.

[0041] 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 component from another and are not intended to signify location or importance of the individual components. [0042] Turning now to the figures, especially FIGS. 1 through 3 and 9, exemplary aspects of a snow thrower (e.g., snow thrower 100) are illustrated. Generally, snow thrower 100 includes a body frame 110 defining a mutually-orthogonal vertical direction V, lateral direction L, and transverse direction T.

[0043] In some embodiments, one or more wheels 112 are rotatably attached to body frame 110 to support body frame 110 and generally permit snow thrower 100 to roll along the ground. A handle or handle frame 114 is attached to body frame 110 (e.g., opposite wheels 112) for pushing and directing snow thrower 100.

[0044] As shown, snow thrower 100 may define a discrete body inlet 116 and body outlet 118. For instance, body inlet 116 and body outlet 118 may be defined in fluid communication between an auger chamber 120 defined within body frame 110. Body inlet 116 may be defined at a front portion of body frame 110 (e. g. , upstream of auger chamber 120) to receive snow, such as when snow thrower 100 is propelled forward. Body outlet 118 may be defined at a top portion of body frame 110 (e.g., downstream of auger chamber 120 or upstream of a chute 122) to direct snow from auger chamber 120.

[0045] In some embodiments, body outlet 118 is positioned above body inlet 116 or auger chamber 120 (e.g., along the vertical direction V). Additionally or alternatively, body outlet 118 may be positioned rearward of body inlet 116 (e.g., along the transverse direction T).

[0046] As shown, a chute 122 is attached to body frame 110 to direct snow therefrom. For instance, chute 122 may be generally positioned downstream of body inlet 116 and body outlet 118. As will be described in greater detail below, chute 122 may be rotatably attached such that the direction of snow from snow thrower 100 may be selectively chosen or altered (e.g., by user). Additionally or alternatively, chute 122 may be removably attached such that chute 122 may be selectively separated from body frame 110 (e.g., without the use of any separate tools).

[0047] When assembled, an auger 124 is rotatably mounted within body frame 110 (e.g., to rotate about an auger axis 128). For instance, auger 124 may be housed within auger chamber 120. Additionally or alternatively, auger 124 may extend along auger axis 128 (e.g., parallel to the lateral direction L) between two sidewalls 126 of auger chamber 120. In some embodiments, auger 124 or auger axis 128 is/are positioned beneath body outlet 118.

[0048] A motor 130 (e.g., a single-speed motor or, alternatively, a variable speed motor) is mounted to (or enclosed within) body frame 110. When assembled, motor 130 may be in mechanical communication with auger 124. In some embodiments, a drive assembly 132 couples (e.g., mechanically couples) auger 124 and motor 130.

For instance, a driven belt 134 may be provided between motor 130 and auger 124. Additionally or alternatively, a drive pulley 136 and a driven pulley 138 may be provided between motor 130 and auger 124 (e.g., fixed to motor 130 and auger 124, respectively). In some such embodiments, drive pulley 136 defines a diameter that is smaller than a diameter defined by driven pulley 138. During use, driven belt 134 may be looped around both drive pulley 136 and driven pulley 138 to transfer rotational force from motor 130 to auger 124. An idler pulley 140 may be provided in contact with driven belt 134 between drive pulley 136 and driven pulley 138 (e.g., to maintain tension on driven belt 134).

[0049] Although drive assembly 132 is shown between auger 124 and motor 130, it is understood that alternative embodiments may include any suitable configuration for transferring movement from motor 130 to auger 124. As an example, motor 130 may be directly coupled to auger 124. As another example, a gear train having multiple toothed gears may be enmeshed in mechanical communication between motor 130 and auger 124.

[0050] During use, as motor 130 motivates auger 124 to rotate about auger axis 128, snow may generally be motivated (e.g., rearward) from body inlet 116 and (e.g., upward) to body outlet 118.

[0051] In certain embodiments, motor 130 further motivates forward movement of snow thrower 100. For instance, auger 124 may be configured to contact the ground during use. Optionally, a radial tip or edge of auger 124 may be sized to extend beyond a bottommost portion of body frame 110. As auger 124 rotates, friction between auger 124 and the contacting ground may generally motivate or propel snow thrower 100 forward. In additional or alternative embodiments, a separate secondary motor (not pictured) may be mechanically coupled to wheels 112 to motivate rotation thereof independently of motor 130 or auger 124. [0052] In optional embodiments, a lighting assembly 144 is provided on snow thrower 100. For instance, lighting assembly 144 may be mounted to body frame 110. Additionally or alternatively, lighting assembly 144 may be located above body inlet 116 and directed forward therefrom (e.g., to illuminate a region or area directly in front of body inlet 116). Generally, lighting assembly 144 includes one or more suitable light sources (LEDs, halogen bulbs, fluorescent bulbs, etc.) to generate light emissions therefrom. Moreover, such light sources may be housed within a suitable ballast and covered, at least in part, by a suitable transparent or translucent cover.

[0053] In some embodiments, a controller 146 is provided in operable

communication (e.g., electrical communication) with one or more portions of snow thrower 100 to direct features or operations thereof. Controller 146 may include a memory (e.g., non-transitive memory) and one or more microprocessors, CPUs or the like, such as general or special purpose microprocessors operable to execute programming instructions or micro-control code associated with operation of snow thrower 100. The memory may represent random access memory such as DRAM, or read only memory such as ROM or FLASH. In some embodiments, the processor executes programming instructions stored in memory. For certain embodiments, the instructions include a software package configured to operate snow thrower 100. The memory may be a separate component from the processor or may be included onboard within the processor. Alternatively, controller 146 may be constructed without using a microprocessor [e.g., using a combination of discrete analog or digital logic circuitry, such as switches, amplifiers, integrators, comparators, flip-flops, logic gates (e.g., AND, OR, XOR, NOT, NOR, NAND, etc.), and the like] to perform control functionality instead of relying upon software.

[0054] Controller 146, or portions thereof, may be provided in a variety of locations throughout snow thrower 100. In exemplary embodiments, controller 146 is located within the body frame 110 (e.g., along with one or more suitable power sources or batteries 148 that provide an electrical current or voltage to controller 146). In other embodiments, controller 146 may be provided at any suitable location within snow thrower 100. Input/output (“I/O”) signals may be routed between controller 146 and various operational components of snow thrower 100. For example, motor 130, lighting assembly 144, or one or more sensors may be in communication with controller 146 via one or more signal lines or shared communication busses.

[0055] One or more power sources or batteries 148 may be provided on snow thrower 100 to selectively supply power (e.g., in the form of a direct electrical current) to motor 130, lighting assembly 144, or other elements of snow thrower 100. For instance, two or more batteries 148 may be received within a battery compartment 150. In some such embodiments, snow thrower 100 is configured to selectively operate in both a single-battery mode and a dual-battery mode. For instance, controller 146 may be configured to alternately implement a single-battery mode and a dual-battery mode based on whether one or two batteries 148 are detected.

Optionally, the batteries 148 may be selectively received within battery compartment 150 in an electrical series or parallel connection. Controller 146 may detect the presence of the batteries 148 based on a received voltage from battery compartment 150 (or any other suitable method). In the single-battery mode, only a single battery 148 (or a single battery that includes a minimum threshold of stored electrical energy) is received within battery compartment 150 and provides power to at least a portion of snow thrower 100 (e.g., motor 130 or lighting assembly 144). In the dual-battery mode, two discrete batteries 148 having a minimum threshold of stored electrical energy are received within battery compartment 150 and mutually provide power to at least a portion of snow thrower 100 (e.g., motor 130 or lighting assembly 144). Thus, controller 146 may automatically detect the presence of one battery or two batteries and select the appropriate mode, accordingly.

[0056] In additional or alternative embodiments, snow thrower 100 is configured to support on-board charging of the batteries 148 (e.g., within battery compartment 150). For example, an extension cord or plug may be provided on battery

compartment 150 to connect to a suitable alternating current (AC) power source (e.g., municipal power grid, generator, etc.). When connected to the AC power source, a received AC current may be converted to a direct current (DC) that is supplied to, and stored within, the batteries 148. In some such embodiments, controller 146 includes a serial charging circuit configured to charge at least two batteries 148 sequentially when connected to the AC power source. For instance, controller 146 may initially charge a first battery 148 within battery compartment 150 and then charge a second battery 148 within battery compartment 150. In some such embodiments, charging of the second battery 148 may only be initiated subsequent to (e.g., in response to) a predetermined maximum charge being established within a first battery 148. In other embodiments, charging of a second battery 148 is initiated subsequent to one or more predetermined intermediate thresholds (i.e., threshold below the maximum charge) being established within the first battery 148. Additionally or alternatively, charging of first and second batteries 148 may be alternately initiated according to

predetermined step sequence. Optionally, controller 146 may be further configured to block the normal discharge paths (e.g., from both batteries 148) when connected to AC power. Thus, while charging, operation of motor 130 may be prevented.

[0057] As noted above, motor 130 may be a variable speed motor. Thus, the speed of motor 130 (e.g., and thus the rotational speed of auger 124) may be selectively varied. In some such embodiments, a speed selector input is provided to direct the rotation speed of motor 130 or auger 124. For instance, speed selector input may be provided as a linear displacement switch 152 in operable communication with motor 130. Linear displacement switch 152 may configured to direct rotation speed at the variable speed motor 130 according to a linear position of the linear displacement switch 152. Thus, as the longitudinal position of linear displacement switch 152 is varied (e.g., along a switch axis), the rotational speed of motor 130 may also be varied. In exemplary embodiments, speed selector input is electrically coupled to controller 146 or directly coupled between motor 130 and a power source (e.g., batteries 148). The longitudinal position of linear displacement switch 152 may be communicated to motor 130 (e.g., indirectly or indirectly) as a speed signal from linear displacement switch 152.

[0058] In some embodiments, handle frame 114 generally extends along a longitudinal axis 154 from body frame 110. Specifically, handle frame 114 extends longitudinally from a mount end 156 to a grip end 158. At mount end 156, handle frame 114 is joined to body frame 110 (e.g., directly or through an intermediate mounting assembly, such as handle-angle assembly 160). Thus, mount end 156 is proximal to body frame 110. By contrast, grip end 158 is longitudinally spaced apart from body frame 110. In other words, in comparison to mount end 156, grip end 158 is distal to body frame 110. It is noted that although handle frame 114 extends linearly along longitudinal axis 154 in exemplary embodiments, other embodiments may provide a curvilinear extension between handle frame 114 and grip end 158 while still generally extending along a defined longitudinal axis 154.

[0059] In certain embodiments, a handlebar 162 is provided at grip end 158 of handle frame 114. Handlebar 162 may provide a segment or defined region at which a user may grasp handle frame 114 during use of snow thrower 100. For instance, a handlebar 162 may extend laterally between a first end 164 and a second end 166. Optionally, a discrete lateral arm 184 may be provided at first end 164 and second end 166.

[0060] Turning especially to FIGS. 4 and 5, various perspective views are provided of handle frame 114 (e.g., at grip end 158). As shown, exemplary embodiments include one or more grip-engaged paddles 168, 170 mounted on handlebar 162. For instance, a pair of grip-engaged paddles 168, 170 may be mounted on opposite lateral sides of handlebar 162. As shown, the grip-engaged paddles 168, 170 are movably mounted at grip end 158 and can be selectively engaged, for instance, by a user’s hand while grasping or otherwise contacting handlebar 162. For instance, a grip-engaged paddle 168 or 170 may extend laterally across, at least a portion of handlebar 162. During use, squeezing or pulling the grip-engaged paddle 168 or 170 toward handlebar 162 may force the grip-engaged paddle 168 or 170 to an operative position, while releasing the grip-engaged paddle 168 or 170 may permit the grip-engaged paddle 168 or 170 to extend forward from handlebar 162 to an inoperative position. In some such embodiments, a paddle spring 172 biases the grip- engaged paddle 168 or 170 to the inoperative position.

[0061] In certain embodiments, a grip-engaged paddle 168 or 170 extends (e.g., laterally) between a free end 174 and a pivot end 176. Pivot end 176 provides a mounting point at which the grip-engaged paddle 168 or 170 is fixed to handlebar 162, along with a pivot axis about which free end 174 pivots. In some such embodiments, the grip-engaged paddle 168 or 170 spans across a center line (e.g., lateral center point between first end 164 and second end 166) of handlebar 162. Specifically, the free end 174 may be located on one side of the center line, while the pivot end 176 is located on the opposite side of the center line. In some such embodiments, the pivot end 176 is located closer to second end 166 of handlebar 162 than it is first end 164 of handlebar 162, while the free end 174 is located closer to first end 164 of handlebar 162 than it is second end 166 of handlebar 162. If a pair of grip-engaged paddles 168 and 170 is provided, the second paddle 170 may have a pivot end 176 located closer to first end 164 of handlebar 162 than it is second end 166 of handlebar 162, while the free end 174 of the second paddle 170 is located closer to second end 166 of handlebar 162 than it is first end 164 of handlebar 162.

[0062] Advantageously, the grip-engaged paddle 168 or 170 may simulate linear movement (i.e., non-pivoting movement) while providing a relatively simple mounting configuration.

[0063] Optionally, an interface panel 178 may be located on handlebar 162 (e.g., at or across the center line between first end 164 and second end 166). Interface panel 178 may include one or more inputs (e.g., tactile buttons, knobs, toggles, or capacitive touch panels) in operable communication with controller 146. In some embodiments, both the first paddle 168 and the second paddle 170 extend through interface panel 178 (e.g., laterally in a cross pattern, as illustrated in FIG. 5).

[0064] In exemplary embodiments, a grip-engaged paddle 168, 170 effectuates a safety condition. As an example, activation of motor 130 or rotation of auger 124 may be conditioned upon one or both of the grip-engaged paddles 168, 170 being actuated (e.g., grasped) or otherwise moved to the operative position. In some such embodiments, controller 146 is configured to receive a user-initiated start signal (e.g., from an input on interface panel 178) and a paddle signal (e.g., from one or more of the grip-engaged paddles 168, 170, or a switch mechanically coupled thereto) before transmitting an activation signal to motor 130 and initiating the rotation of auger 124. Controller 146 may be further configured to require continuous receipt of the paddle signal while motor 130 remains active. Loss of the paddle signal may cause controller 146 to halt activation of motor 130 (i.e., deactivate motor 130) or rotation of the auger 124. Thus, releasing one or both of the grip-engaged paddles 168, 170 (e.g., such that both paddle 168 and 170 are in the inoperative position) may result in deactivation of auger 124.

[0065] Optionally, the paddle signal may be provided in the form of an open signal path. For instance, transmission of the paddle signal may be embodied as closing an electrical path (e.g., to/from controller 146). In turn, loss of the paddle signal may be embodied as opening the electrical path. Thus, deactivation of motor 130 may be virtually instantaneous upon release of one or both of the grip-engaged paddles 168, 170.

[0066] As shown, especially in FIGS. 6 through 8, handle frame 114 may include a telescoping assembly 180. In some embodiments, telescoping assembly 180 includes a telescoping tube 182 into which another portion of handle frame 114 (e.g., reception tube 186) can slide. For instance, a lateral arm 184 of handle frame 114 may include a corresponding telescoping tube 182 that receives another portion of lateral arm 184 e.g., reception tube 186) to selectively vary an overall longitudinal length between grip end 158 and mount end 156 of handle frame 114.

[0067] In optional embodiments, a telescope lock 188 may be provided with telescoping assembly 180. When assembled, telescope lock 188 may selectively secure or lock handle frame 114 in a particular or selected overall longitudinal length. In some such embodiments, a telescope shroud 190 is mounted to telescoping tube 182 to secure telescope lock 188 thereon. Telescope shroud 190 may permit rotation of telescope lock 188 on telescope shroud 190 (e.g., about an axis perpendicular to the longitudinal axis 154). An internal prong 192 may extend from telescope lock 188 inward, toward telescoping tube 182. Rotation of telescope lock 188 may vary the extension of internal prong 192 and, thereby, bring internal prong 192 closer to or further from longitudinal axis 154 (e.g., according to the direction of rotation). A lock aperture or opening 194 may be defined through an outer wall of telescoping tube 182 to receive internal prong 192. In turn, internal prong 192 of telescope lock 188 may be permitted to selectively engage, for instance, a reception tube 186 within telescoping tube 182 (e.g., to restrict further longitudinal movement of reception tube 186 relative to telescoping tube 182). As an example, one or more grooves or openings may be defined through reception tube 186 (e.g., perpendicular to the longitudinal axis 154) to receive internal prong 192, and thereby define a predetermined setting for the overall distance between grip end 158 and mount end 156 of handle frame 114.

[0068] Turning now to FIGS. 9 through 13, various views are provided of snow thrower 100, and in particular a handle-angle assembly 160 of handle frame 114. As shown, handle-angle assembly 160 includes an upper segment 196 (e.g., as or as part of telescoping tube 182) and a lower segment 198 (e.g., mounted or fixed to body frame 110). In some such embodiments, a segment collar 200 attaches upper segment 196 and lower segment 198.

[0069] When assembled, handle-angle assembly 160 generally permits a user to selectively set or change an angle of handle frame 114 relative to body frame 110. In certain embodiments, segment collar 200 defines a lateral handle axis 202 (e.g., parallel to lateral direction L or auger axis 128) about which upper segment 196 is rotatable relative to lower segment 198 or body frame 110. As shown in FIG. 9, some embodiments provide for multiple unique attached positions of handle frame 114 on body frame 110. For instance, along with an attached-use position (indicated at UP), one or more attached-stow positions may be provided, such as an attached forward- position (indicated in phantom lines at FP).

[0070] In exemplary embodiments, 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, handle cup 206 may rotate with upper segment 196 relative to base cup 208 and lower segment 198. For instance, handle cup 206 may selectively or alternately engage base cup 208 (e.g., to prevent rotation relative to base cup 208) and disengage base cup 208 (e.g., to permit rotation relative to base cup 208).

Optionally, a cup shroud 210 may be provided in handle-angle assembly 160 (e.g., on upper segment 196 or lower segment 198) and cover or enclose at least a portion of segment collar 200 (e.g., handle cup 206 or base cup 208).

[0071] A pair of lateral interface teeth 212, 214between base cup 208 and handle cup 206 may define a plurality of predetermined pivot positions for handle frame 114. For instance, a plurality of teeth 214 defined on base cup 208 may extend laterally toward upper segment 196, while a plurality of teeth 212 defined on handle cup 206 may extend laterally toward base cup 208.

[0072] During use of snow thrower 100, the pair of lateral interface teeth 212, 214 may be enmeshed such that relative rotation is prevented. However, during angle adjustments, the pair of lateral interface teeth 212, 214 may be laterally separated such that handle cup 206 is permitted to rotate about the lateral handle axis 202 and relative to base cup 208.

[0073] In some embodiments, a bracket clamp 216 selectively clasps base cup 208 and handle cup 206 (e.g., such that base cup 208 and handle cup 206 are held together and the pair of lateral interface teeth 212, 214 are enmeshed). Bracket clamp 216 may include a clamp pin 218 that extends (e.g., laterally) through segment collar 200 (e.g., through handle cup 206 or base cup 208 along lateral handle axis 202). Additionally or alternatively, clamp pin 218 may extend (e.g., along lateral handle axis 202) through upper segment 196 and lower segment 198.

[0074] On one lateral end of clamp pin 218, a cam latch 220 may be provided.

On the other lateral end of clamp pin 218, a retention flange 222 may be provided. Thus, handle cup 206 and base cup 208 may be sandwiched (e.g., laterally) between cam latch 220 and retention flange 222. When assembled, cam latch 220 may be selectively pivoted (e.g., perpendicular to the lateral handle axis 202) between a clasped position (e.g., as illustrated in FIG. 10) and a released position (not pictured). In the clasped position, an eccentric lobed surface of cam latch 220 may be held against handle cup 206 (e.g., a bracket thereol) and force handle cup 206 and base cup 208 together. In the released position, the eccentric lobed surface of cam latch 220 may be held away from handle cup 206, permitting lateral separation between handle cup 206 and base cup 208. Optionally, a clamp spring 224 may be located about clamp pin 218 in biased engagement to provide a separating force between handle cup 206 and base cup 208 (or between upper segment 196 and lower segment 198).

[0075] Optionally, multiple handle angle assemblies 160 may be provided on handle frame 114. For instance, as shown, a discrete handle-angle assembly 160 may be provided on each lateral side or arm 184 of handle frame 114.

[0076] Turning now especially to FIGS. 1 and 14 through 18, as well as FIG. 28, in some embodiments, snow thrower 100 includes a rotatable chute assembly 226 for selectively rotating chute 122 about a chute axis 228. For instance, the position or rotation of chute 122 may be based on a relative position of a hand grip 236. In exemplary embodiments, 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 wire 234.

[0077] Generally, rotation of a portion of actuator assembly 230 in a first direction (e.g., clockwise or counterclockwise about a grip axis 238) may pull tension wire 234 and rotate chute 122 in a corresponding first direction (e.g., clockwise or counterclockwise about chute axis 228). Likewise, rotation of a portion of actuator assembly 230 in a second direction (e.g., counterclockwise or clockwise about grip axis 238) may pull tension wire 234 and rotate chute 122 in a corresponding second direction (e.g., counterclockwise or clockwise about chute axis 228). For instance, a hand grip 236 of actuator assembly 230 may be in mechanical communication with a chute collar 204 on which chute 122 is mounted. Optionally, mechanical

communication may be provided via tension wire 234 and one or more pulleys 242, 248 between hand grip 236 and chute collar 204. As hand grip 236 is rotated clockwise/counterclockwise, a corresponding movement may thus be effectuated at collar 204 and chute 122 through tension wire 234 or pulleys 242, 248.

[0078] In exemplary embodiments, hand grip 236 is attached to handle frame 114 (e.g., proximal to handlebar 162 or free end 174). For instance, hand grip 236 may be rotatably attached to handle frame 114 to move about a grip axis 238 (e.g., parallel to the lateral direction L or auger axis 128). In some such embodiments, hand grip 236 is rotatably fixed to a grip bracket 240 that is secured to a lateral arm 184 of handle frame 114.

[0079] When assembled, hand grip 236 is in mechanical communication with an actuator pulley 242 (e.g., rotatably mounted to or enclosed within grip bracket 240). As an example, one or more gears 244, 246 may be provided between hand grip 236 and actuator pulley 242 to direct or transfer rotational movement of hand grip 236 to actuator pulley 242. Optionally, a pair of enlarged wire lobes may be provided on tension wire 234 and fixed within actuator pulley 242, thereby securing the relative position of tension wire 234 to pulley 242. Additionally or alternatively, one or more line springs 245 may be provided along tension wire 234. For instance, a discrete line spring 245 may be provided at each end of tension wire 234 (e.g., within pulley 242). An engagement collar 247 may be forced against a corresponding end of tension wire 234 (e.g., at the corresponding lobe of wire 234) by a corresponding line spring 245. When assembled, each line spring 245 may be maintained in tension (e.g., compressive tension) within pulley 242 and provide an in-line force on wire 242, thereby adding tension to line 242 and advantageously take up tolerances.

[0080] In some such embodiments, a grip gear 244 is fixed to hand grip 236 (e.g., coaxial therewith to rotate about grip axis 238). Additionally or alternatively, an intermediate gear 246 may be fixed to actuator pulley 242 (e.g., to rotate therewith). As shown, the teeth of grip gear 244 may be enmeshed with the teeth of intermediate gear 246 such that rotation of grip gear 244 is transferred to intermediate gear 246, which is in turn transferred to actuator pulley 242. Optionally, a diameter (e.g., root diameter) of grip gear 244 may be greater than a corresponding diameter (e.g., root diameter) of intermediate gear 246. When assembled, a gear ratio of grip gear 244 to intermediate gear 246 may be less than one. In some embodiments, the gear ratio is greater than 0.1. Advantageously, relatively large rotational movements of hand grip 236 may be required to effectuate relatively small rotational movements of actuator pulley 242 (e.g., and thereby tension wire 234).

[0081] As shown, tension wire 234 may mechanically couple actuator assembly 230 to gear assembly 232 at a base pulley 248. Optionally, a pair of enlarged wire lobes may be provided on tension wire 234 and fixed within base pulley 248, thereby securing the relative position of tension wire 234 to pulley 248. A base gear 250 or chute gear 252 may be provided in mechanical communication with base pulley 248 such that rotation of base pulley 248 is generally transferred to chute 122 (e.g., at a collar 204 disposed about chute axis 228).

[0082] In some embodiments, base pulley 248 is fixed to a base gear 250 (e.g., to rotate therewith). One or both of base pulley 248 and base gear 250 may be rotatably mounted within body frame 110. Moreover, when mounted, base gear 250 may be mechanical communication with a chute gear 252 (e.g., enmeshed therewith).

[0083] In certain embodiments, chute gear 252 is fixed to a chute collar 204 that supports chute 122. For instance, chute gear 252 may be mounted to chute collar 204 (e.g., via one or more mechanical fasteners, adhesives, etc.) and disposed about chute axis 228, such that chute collar 204 and chute gear 252 may rotate together (e.g., and with chute 122) to vary the rotational position of chute 122. Movement of tension wire 234 (e.g., as initiated at hand grip 236) may cause base pulley 248 and base gear 250 to rotate. The rotation at base gear 250 may then be transferred to chute gear 252, collar 204, and chute 122.

[0084] Turning now to FIGS. 19 through 21, various views are provided of chute 122. In certain embodiments, such as those illustrated, snow thrower 100 may include a removable chute assembly. Advantageously, chute 122 may be selectively removed or reattached to body frame 110 without the use of tools, as would typically be otherwise required.

[0085] In some embodiments, collar 204 is attached to body frame 110 about body outlet 118. As described above, collar 204 may be fixed to a rotatable chute gear 252 or, alternatively, directly fixed to a portion of body frame 110 (e.g., by one or more suitable mechanical fasteners, adhesives, etc.). In certain embodiments, collar 204 is formed as a ring positioned coaxial with body outlet 118.

[0086] In additional or alternative embodiments, chute 122 is attached to body frame 110, for instance, at the collar 204. When assembled, chute 122 may be in selective rotatable engagement with collar 204. Thus, chute 122 may selectively rotate relative to collar 204 (e.g., about chute axis 228 or vertical direction V) while resting thereon. In optional embodiments, chute 122 may include a base flange 256 that extends radially outward from a guide column 258 through which snow is directed.

As shown, base flange 256 may rest upon at least a portion of collar 204. In some such embodiments, base flange 256 extends generally about chute axis 228, but defines one or more channels or cutouts. For example, a tab channel 260 may be defined as a vertical gap that extends along a circumferential length of base flange 256. As an additional or alternative example, a secondary channel 262 may be defined as a separate vertical gap that is spaced apart (e.g., circumferentially) from tab channel 260 and extends along another circumferential length of base flange 256. Optionally, the circumferential length of secondary channel 262 may be greater than the circumferential length of tab channel 260.

[0087] As shown, collar 204 may include a resilient release tab 264 at a predefined circumferential location. For instance, resilient release tab 264 may generally be biased vertically and extend upward (e.g., towards base flange 256). Optionally, a spring (e.g., leaf spring) is formed with collar 204 such that, for example, resilient release tab 264, the spring formed with tab 264, and collar 204 are integral with each other (e.g., formed as unitary monolithic member). In certain embodiments, resilient release tab 264 defines a complementary shape or profile to tab channel 260. Additionally or alternatively, resilient release tab 264 may define a circumferential length that is approximately equal to or less than the circumferential length of tab channel 260. Thus, when assembled, resilient release tab 264 may extend (e.g., vertically) through, and be received by, tab channel 260. As shown, the assembled position of resilient release tab 264 within tab channel 260 may generally restrict rotation of base flange 256 and chute 122 relative to collar 204.

[0088] In additional or alternative embodiments, collar 204 may include a secondary tab 266 at a predefined circumferential location (e.g., spaced apart from resilient release tab 264). For instance, secondary tab 266 may extend vertically in a rigid or fixed position relative to the rest of collar 204. As shown, secondary tab 266 may define a circumferential length that is significantly shorter than the

circumferential length of secondary channel 262. Thus, when assembled, secondary tab 266 may extend (e.g., vertically) through and be received by secondary channel 262. Nonetheless, notwithstanding resilient release tab 264, the relatively short circumferential length of secondary tab 266 may allow base flange 256 or chute 122 to rotate slightly (e.g., within a predefined angle range that is less than 90°) relative to collar 204.

[0089] In exemplary embodiments, chute 122 further includes a plurality of radial tabs 270 circumferentially spaced apart (e.g., from each other) and below base flange 256. In some such embodiments, the plurality of radial tabs 270 are all vertically spaced apart from base flange 256. In particular, a vertical gap may be defined between a bottom surface of base flange 256 and a top surface of the radial tabs 270. When assembled, collar 204 may be generally positioned within the vertical gap. For instance, at least a portion of collar 204 may be selectively held between base flange 256 and the plurality of radial tabs 270 (e.g., such that vertical movement of the chute 122 relative to collar 204 is restricted). In some such embodiments, collar 204 defines a plurality of interior slots 272 that generally correspond to and complement the plurality of radial tabs 270.

[0090] During assembly or disassembly, the chute 122 may be rotated relative to collar 204 such that the radial tabs 270 are vertically aligned with the interior slots 272 before being moved vertically relative to collar 204 (e.g., such that the radial tabs 270 pass through the slots 272). For instance, the attachment of the chute 122 to body frame 110 may require, first, vertically aligning the plurality of radial tabs 270 with the plurality of interior slots 272, and, then, further aligning secondary tab 266 with secondary channel 262. Chute 122 may subsequently be moved (e.g., downward) until base flange 256 contacts an upper surface of collar 204, or until the plurality of radial tabs 270 are fully below collar 204. Once tabs 270 are below collar 204, chute 122 may be rotated relative to collar 204 (e.g., about chute axis 228) until tab channel 260 is vertically aligned with resilient release tab 264 or secondary tab 266 contacts an end point of secondary channel 262. When resilient release tab 264 and tab channel 260 are vertically aligned, resilient release tab 264 may spring upward into tab channel 260 and thereby restrict further rotation of chute 122 relative to collar 204.

[0091] Removal of the chute 122 from body frame 110 may require pressing resilient release tab 264 downward (or otherwise forcing resilient release tab 264 from tab channel 260) and performing the attachment steps in reverse.

[0092] Turning now to FIGS. 22 through 27, various views are provided of portions of a battery compartment 150 for snow thrower 100 according to exemplary embodiments of the present disclosure. As noted above, certain embodiments of snow thrower 100 may include a battery compartment 150 (e.g., at a rear portion 294 of body frame 110) to receive one or more batteries 148 therein.

[0093] As shown, battery compartment 150 includes one or more interior walls (e.g., one or more sidewalls 274 and base wall 276) that define a battery cavity 278. in some embodiments, battery cavity 278 extends from an upper portion 280 to lower portion 282. Additionally or alternatively, upper portion 280 may define an opening 284 for battery cavity 278 through which the battery 148 may pass (e.g., for insertion or removal of battery 148 from battery compartment 150). Thus, battery cavity 278 may generally be described as a vertical cavity, though, as illustrated, battery cavity 278 may extend at a slight angle (e.g., nonparallel or nonorthogonal angle) relative to the vertical direction V.

[0094] In exemplary embodiments, battery compartment 150 includes one or more rims 286, 288 that extend about at least a portion of battery cavity 278. As an example, an inner rim 286 may extend about the opening 284 of battery cavity 278. Additionally or alternatively, inner rim 286 may extend above (e.g., higher than battery cavity 278). The vertical extremes or maximum of inner rim 286 may thus be higher than any battery 148 received within battery compartment 150. As an additional or alternative example, and outer rim 288 may extend about the opening 284 of battery cavity 278. In some such embodiments, outer rim 288 is radially spaced from inner rim 286 such that a recessed groove 290 is defined between inner rim 286 and outer rim 288 (e.g., radially outward from battery cavity 278). Optionally, recessed groove 290 may be generally slope or decline from a front portion 292 to a rear portion 294. During use, recessed groove 290 may catch or redirect fluid (e.g., liquid water between inner rim 286 and outer rim 288).

[0095] In further embodiments, a compartment lid 296 is attached to body frame 110 to selectively cover battery compartment 150. For instance, compartment lid 296 may be movable (e.g., rotatable) between an open position and a closed position. In the open position, compartment lid 296 may be spaced apart from battery cavity 278 and opening 284, and access to battery cavity 278 (e.g., by user) may be generally permitted. By contrast, in the closed position, compartment lid 296 may extend over or across at least a portion of opening 284, and access to battery cavity 278 may generally be restricted. In optional embodiments, compartment lid 296 includes an inner bp 298 the generally extends downward (e.g., towards battery compartment 150 in the closed position). Optionally, inner bp 298 may extend about at least a portion of opening 284.

[0096] In the closed position, inner bp 298 may be received within recessed groove 290. For instance, inner bp 298 may rest on an upper surface of recessed groove 290 and radially separate inner rim 286 from outer rim 288. Advantageously, snow or liquid water on compartment lid 296 may thus be directed to recessed groove 290 and away from battery cavity 278.

[0097] Turning especially to FIGS. 24 through 27, exemplary embodiments of battery compartment 150 include a biased ejection assembly 300. Generally, biased ejection assembly 300 includes one or more springs 302 or load plates 304 (e.g., at the lower portion 282 of battery compartment 150) to motivate or bias the battery 148 within battery cavity 278 upward and away from base wall 276. Locking the battery 148 in place within battery cavity 278 (e.g., by moving compartment lid 296 to the closed position or engaging an internal latch 306 within battery compartment 150) may force and hold biased ejection assembly 300 downward. However, unlocking or releasing the battery 148 (e.g., by moving compartment lid 296 to the open position or disengaging an internal latch 306) may permit biased ejection assembly 300 to motivate the battery 148 upward (e.g., such that a user may advantageously and conveniently access the battery 148 above its locked position).

[0098] As shown in the exemplary embodiments of FIG. 24, biased ejection assembly 300 may include an aligned linear spring 302 (e.g., compression spring, air spring, hydraulic spring, etc.) and load plate 304 mounted within battery compartment 150 to selectively extend through a plate opening 308 defined in base wall 276 of battery compartment 150. Specifically, spring 302 and load plate 304 may be linearly aligned with plate opening 308. In some embodiments, a guide or support housing 310 is mounted below battery cavity 278 and supports linear spring 302 therein. Optionally, a plate flange 312 may extend radially from load plate 304 to selectively engage, for instance, a botom surface of base wall 276. In some such embodiments, plate flange 312 extends beyond plate opening 308 or generally defines a larger radial width than plate opening 308. As spring 302 motivates load plate 304 upward, vertical movement may be restricted, for instance, by contact between base wall 276 and plate flange 312.

[0099] As shown in the other exemplary embodiments of FIG. 25, biased ejection assembly 300 may include a pivoting load plate 304 and spring 302 (e.g., compression spring) and load plate 304 mounted within battery compartment 150 to selectively drive one pivotable end (e.g., interior end 316) of load plate 304 through a plate opening 308 defined in base wall 276 of batery compartment 150. Specifically, spring 302 and load plate 304 may be pivotably mounted below batery compartment 150. An exterior end 314 of load plate 304 may be aligned with spring 302, which generally biases exterior end 314 downward. Optionally, spring 302 may be mounted to botom surface of base wall 276 (e.g., outside of batery cavity 278). An interior end 316 of load plate 304, opposite from exterior end 314 about a fulcrum point, may be aligned with plate opening 308. As spring 302 motivates exterior end 314 downward, interior end 316 may be motivated upward (e.g., in engagement with a batery 148 within batery cavity 278).

[00100] As shown in additional or alternative exemplary embodiments, batery compartment 150 may define one or more latch slots 318. For instance, a latch slot 318 may be defined through a sidewall 274 of batery compartment 150. Latch slot 318 may receive a corresponding body latch 320 on batery 148, which in turn, may lock a corresponding battery 148 within battery cavity 278 (e.g., in opposition to the biasing force supplied from biased ejection assembly 300).

[00101] This written description uses examples to disclose the invention, including the best mode, and also to enable any person skilled in the art to practice the invention, including making and using any devices or systems and performing any incorporated methods. The patentable scope of the invention is defined by the claims, and may include other examples that occur to those skilled in the art. Such other examples are intended to be within the scope of the claims if they include structural elements that do not differ from the literal language of the claims, or if they include equivalent structural elements with insubstantial differences from the literal languages of the claims.
