Description
- The present subject matter generally relates to snowblowers and related methods and, more particularly, to snowblower deflector control devices, systems, and related methods.
- Snowblowers, also known as snowthrowers, are known to have upright discharge chutes through which a snow stream can be thrown or discharged. It is common for the chute to have a pivotal deflector on top of the chute for adjusting the trajectory of the thrown snow stream. In some aspects, the pivotal motion associated with the deflector can be manually controlled by manually adjusting an integrally formed handle of the deflector. A user must walk around the snowblower and grab the handle to move the deflector to a desired position. Friction between the deflector and chute can retain the deflector in the adjusted position. In other aspects, the pivotal motion associated with the deflector can be controlled by a joystick type control member operable via an electric motor.
- Each of these types of control mechanisms has drawbacks. For example, manually controlled systems require the user to be able to reach the handle of the deflector. This requires the user to come around from the usual operating position behind the snowblower to one side in order to be adjacent to the deflector and to be able to reach the handle on the deflector. This can be both physically tiring and inconvenient, particularly where one must redirect the trajectory of the snow stream frequently. More advanced systems which control the deflector via an electric motor can add costs to the design and manufacture of the snowblower and may contain a large number of components that can break or otherwise fail.
- Thus, despite the number of snowblowers having controllable deflectors on the market, a simpler, less expensive and durable control mechanism for quickly and easily operating the deflector is needed. The improved control mechanism further includes a novel visual aspect allowing users to actively select and choose discrete increments by which the deflector can be adjusted.
- In accordance with this disclosure, snowblower deflector control devices, systems, and methods are provided. In one aspect, a snowblower deflector control device is provided. The snowblower deflector control device externally disposed from a machine handle of the snowblower. The control device can include a control member and a guide plate. The control member can comprise a longitudinal shaft and a projection disposed along the shaft. The guide plate can be adapted to receive a portion of the control member. The guide plate can comprise a plurality of gates disposed at regularly spaced intervals from a first end to a second end, and the projection of the control member can be lockable within at least one gate of the plurality of gates.
- In another aspect, a pivotal snowblower deflector control system is provided. The deflector control system can include a control member, a guide plate adapted to receive a portion of the control member, a deflector hingedly mounted on a snowblower discharge chute, and a linking member coupling a portion of the control member to a portion of the deflector. The guide plate can include a plurality of gates disposed at regularly spaced intervals from a first end to a second end. When the control member is proximate the first end of the guide plate the deflector can be at a first angle with respect to a horizontal axis, and when the control member is proximate the second end of the guide plate the deflector can be at a second angle with respect to the horizontal axis. The first angle can be different than the second angle, such as at a greater or smaller angle with respect to the horizontal axis.
- In yet another aspect, a method for controlling or pivoting a snowblower deflector via a snowblower deflector control system is provided. The method can include providing a control member and a guide plate adapted to receive a portion of the control member. The guide plate can comprise a plurality of gates disposed at regularly spaced intervals from a first end to a second end. The method can further include providing a deflector hingedly mounted on a discharge chute and attaching a linking member to a portion each of the control member and the deflector. The method can further include moving the control member between the first end and the second end of the guide plate to raise and lower the deflector.

- The present subject matter provides and/or includes snowblower deflector control devices, systems, and related methods of controlling a pivotal position of a snowblower deflector for adjusting a trajectory of a thrown show stream. In other words, the present subject matter relates to and provides control devices, systems, and methods for pivoting a deflector about a horizontal axis to adjust a trajectory of a thrown snow stream. In one aspect, the control devices and/or systems for pivoting the deflector can provide a lockable control adapted to lock the deflector at a given angle during operation which can comprise mechanical and/or non-frictional locking.
-
FIG. 1 is one embodiment of a snowblower, generally designated SB comprising a snowblower deflector control system, generally designated 100. Snowblower SB can comprise any general or suitable design, and is not limited in any aspect other than being configured to gather, remove, and/or throw the gathered or removed snow. Snowblower SB can be adapted to incorporate suitable snow removal components for gathering snow from the ground and for throwing the gathered snow in a snow stream away from snowblower SB. The gathered snow stream can be thrown from a generally upright or vertically extending discharge chute C. Chute C can be rotatable about a longitudinal axis (not shown) for changing the direction of the snow stream with respect to snowblower SB. -
Deflector control system 100 can comprise one or more deflector control devices including a control device, generally designated 200, a portion of which can be mechanically coupled or linked to a portion of a deflector, generally designated 300 via a linking member, generally designated 400.Control device 200 can be conveniently located on a portion of a machine handle MH proximate the user, thus providing the user with quick and easy access for adjusting the trajectory of thrown snow via moving a control lever orcontrol member 202 ofcontrol device 200. In one aspect, a portion ofcontrol device 200 can be disposed along one or more external surfaces of machine handle MH.Control member 202 can be moved within various discrete positions within a portion ofcontrol device 200 as illustrated in solid and phantom lines. The user can select one of several discrete positions in which to movecontrol member 202 depending on how “open” or “closed”deflector 300 should be (i.e., or at whichangle deflector 300 should be pivoted with respect to a horizontal axis). Machine handle MH can comprise two “leg” portions and a generally U-shaped portion disposed therebetween. A user of snowblower SB can stand behind snowblower SB and control, grip, and/or maneuver the blower via the U-shaped portion of machine handle MH. -
Deflector 300 can be hingedly mounted to a portion of snowblowerchute C. Deflector 300 can be adapted to pivot about a horizontal axis X (FIGS. 2A to 3B ), for example, along or about the double sided arrow shown inFIG. 1 . Pivoting ofdeflector 300 about horizontal axis X (FIGS. 2A to 3B ) can adjust a trajectory of the snow stream being thrown from chute C. As the deflector pivots away from horizontal axis X (e.g.,FIG. 2A , such as when the deflector is raised) the trajectory of thrown snow can be raised. Conversely, as the deflector pivots towards horizontal axis X (e.g.,FIG. 2B such as when the deflector is lowered) the trajectory of thrown snow can be correspondingly lowered. Thus, the trajectory of the thrown snow stream can correspond to an angle α (FIGS. 2A to 3B ) at whichdeflector 300 is disposed with respect to horizontal axis X. - Still referring to
FIG. 1 , linkingmember 400 can comprise at least a first end coupled to a portion ofcontrol device 200 and a second end coupled to a portion ofdeflector 300. Linkingmember 400 can provide a mechanical linkage betweencontrol device 200 anddeflector 300 allowing for physical communication therebetween, such that one or more movements by portions ofcontrol device 200 can initiate one or more movements at a portion ofdeflector 300. Namely, forward pivotal (e.g., clockwise) or rearward pivotal (e.g., counterclockwise) movements applied to controlmember 202 can induce or initiate downward or upward pivotal movement of deflector, respectively, which can decrease or increase angle α at whichdeflector 300 is offset from horizontal axis X (FIGS. 2A to 3B ). - At least a portion of linking
member 400 can be disposed within a housing H of snowblower SB and can extend from housing H proximate a base of chuteC. Linking member 400 can comprise a mechanical linkage for initiating and/or activating pivoting ofdeflector 300. Linkingmember 400 can also comprise a flexibleinner cable 402 disposed in anouter sheath 404.Outer sheath 404 can protectinner cable 402 from wear and tear and/or weathering.Outer sheath 404 can be fixedly disposed between portions ofcontrol device 200 anddeflector 300, and can allowinner cable 402 to be incrementally adjusted, for example, via pulling back and forthinner cable 402 inside portions ofouter sheath 404 to activate a desired snowblower component, such as controlling pivoting ofdeflector 300. In one aspect, an amount of tension initially maintained withininner cable 402 can be increased or decreased upon pivotingcontrol member 202. When the amount of tension withininner cable 402 increases,deflector 300 can pivot downwardly (FIG. 2B ). When the amount of tension withininner cable 402 decreases,deflector 300 can pivot upwardly (FIG. 2A ). - Referring now to
FIGS. 2A and 2B ,deflector control system 100 can further comprise one or more devices such as previously mentioneddeflector 300.FIGS. 3A and 3B are further embodiments of deflector devices or deflectors, generally designated 500.FIGS. 2A and 3A illustratedeflectors FIG. 1 ) is in its most rearward position along line R (FIGS. 1 , 4A, 4B) with respect to controldevice 200, or disposed closer in distance towards the U-shaped end portion of machine handle MH (FIG. 1 ). The most “open” position corresponds to a maximum angle α being disposed betweendeflector 300 and horizontal axis X. Angle α can, for example, range between approximately 0° (fully closed) and approximately 45° or more. In some aspects, angle α can be more than 45°, such as between approximately 45° and approximately 90°. The maximum angle or a fullyopen deflector 300 can vary by shape or deflector design. Opening or raisingdeflector 300 to a fullest extent by a maximum amount produces a highest trajectory of the thrown snow stream. -
FIGS. 2B and 3B illustratedeflectors FIG. 1 ) is in is most forward position along line F (FIGS. 1 , 4A, 4B) with respect to controldevice 200, or disposed closer in distance towards housing H and chute C of snowblower SB. Closing or loweringdeflector 300 by pivoting towards horizontal axis X can lower the trajectory of the thrown snow stream. In some aspects, the most “closed” position corresponds to when angle α is between approximately 0° and 5° with respect to horizontal axis X. - As
FIGS. 2A and 2B illustrate,deflector 300 can be disposed over a portion of chute C and hingedly mounted thereto.Deflector 300 can pivot abouthinge 302 as indicated by the double sided arrows, and can increase or decrease angle α from horizontal axis X. The amount by which deflector 300 pivots can be controlled viacontrol device 200 and linkingmember 400 of system 100 (FIG. 1 ) as more fully described below. Whendeflector 300 is fully raised such as inFIG. 2A , the trajectory of the snow stream is maximized. Whendeflector 300 is fully closed, such as inFIG. 2B , the trajectory of the snow stream is minimized and/or the flow of snow from chute C is prohibited or blocked by a portion ofdeflector 300. - Linking
member 400 can comprise an inner actuation cable coupled to portions of each ofcontrol device 200 and deflector 300 (or 500,FIGS. 3A and 3B ). Thus, pivotal and/or fore/aft movements (e.g., along lines R and F,FIG. 1 ) ofcontrol member 202 ofcontrol device 200 allow a user to increase tension or decrease tension associated withinner cable 402 by a selective amount for inducing pivotal movement ofdeflector 300. AsFIGS. 2A and 2B illustrate,outer sheath 404 of linkingmember 400 can in one aspect be fixedly held at a first bracketedtab portion 304. Flexibleinner cable 402 of linkingmember 400 can be movable within fixed portion ofouter sheath 404 and can at least partially extend therefrom.Inner cable 402 can extend to a second bracketedtab portion 306.Inner cable 402 can be fixedly held within a portion of second bracketedtab portion 306.Outer sheath 404 can be fixedly held and remain stationary at first bracketedtab 304 allowinginner cable 402 to flex between portions of first and second bracketedtab portions deflector 300 abouthinge 302.Inner cable 402 can be spaced apart from a portion ofhinge 302. - A biasing
member 308 can also be fixedly held between portions of each of first and second bracketedtabs inner cable 402 and biasingmember 308 can each attach to portions ofsecond bracket 306.Biasing member 308 can be disposed on one side ofdeflector 300, and can be at least partially parallel with a portion ofinner cable 402. Portions of biasingmember 308 can expand and/or retract or contract in response to relative movement ofinner cable 402. In addition, biasingmember 308 can maintain a level of tension withininner cable 402, which can be increased or decreased in response to movingcontrol member 202 fore/aft and/or clockwise/counterclockwise. In one aspect, biasingmember 308 can comprise a tension spring or elastic spring adapted to extend and retract for allowing portions ofdeflector 300 to pivot abouthinge 302 and about portions of chute C. - As biasing
member 308 andinner cable 402 are attached to and/or between thesame tabs member 308 can maintain an amount or level of tension acrossinner cable 402 such thatinner cable 402 is not substantially slack.Control member 202 can then be moved forwardly along line F (FIGS. 1 , 4A, 4B) and/or pivoted clockwise about a pivot point P (FIG. 4B ) to increase the amount of tension oncable 402 which in turn can extend biasingmember 308 andpivot deflector 300 downwardly. In further aspects,control member 202 can be moved rearwardly along line R (FIGS. 1 , 4A, and 4B) and/or pivoted counterclockwise about pivot point P (FIG. 4B ) to decrease or relax an amount of tension withincable 402 andpivot deflector 300 upwardly. -
Biasing member 308 can allowdeflector 300 to pivot abouthinge 302 when tension is applied toinner cable 402 via moving control member 202 (FIG. 1 ) in a first direction or when tension applied toinner cable 402 relaxes via movingcontrol member 202 in a second direction. That is, asinner cable 402 flexes or pulls in response to forward movement F (FIG. 1 ) of control member 202 (FIG. 1 ) in a first direction, inner cable can expand, extend, orstretch biasing member 308 and causedeflector 300 to pivot downwardly (e.g., decrease angle α). Conversely, as tension is decreased ininner cable 402 in response to rearward movement R (FIG. 1 ) ofcontrol member 202 in a second direction,inner cable 402 can retract biasingmember 308 and causedeflector 300 to pivot upwardly (e.g., increase angle α). - Still referring to
FIGS. 2A and 2B , movement of control member 202 (FIG. 1 ) induces movement of flexibleinner cable 402 of linkingmember 400, which in turn induces movement of biasingmember 308. For example, as control member 202 (FIG. 1 ) ofcontrol device 200 moves towards a most forward position (e.g., toward afirst end 208′ of aguide plate 208,FIGS. 4A and 4B ) a tension becomes applied toinner cable 402 asinner cable 402 is pulled or flexed. This can cause biasingmember 308 to expand or extend from a retracted position.Deflector 300 can lower, angle α can decrease, and the trajectory of blown snow stream can be lowered. In a similar respect, movingcontrol member 202 rearwardly (e.g., towards asecond end 208″ ofguide plate 208,FIG. 4A ) relieves tension to flexibleinner cable 402 thereby allowing biasingmember 308 to relax or retract from an extended position, angle α can be increased, and the trajectory of blown snow stream can be raised. As biasingmember 308 moves between extended and retracted positions,deflector 300 can pivot abouthinge 302 and a pin orfastening member 310 slideably disposed within portions of a guide slot, generally designated 312 allowdeflector 300 to easily open and close.Biasing member 308 can extend and retract asinner cable 402 is pulled or released, respectively, which allows guide slot ofdeflector 300 to slide about fasteningmember 310. Angles α can be different whencontrol member 202 is proximatefirst end 208′ of guide plate than whencontrol member 202 is proximatesecond end 208″ of guide plate. For example, whencontrol member 202 is proximatefirst end 208′, angle α is less than an angle α whencontrol member 202 is proximatesecond end 208″. As described further below,deflector 300 can be locked in any desirable position with respect to chute C such that the trajectory of snow can be maintained when so desired. -
FIGS. 3A and 3B illustrate a second embodiment of a deflector device or deflector, generally designated 500, ofsystem 100.Deflector 500 can be similar todeflector 300, but can differ in placement or location of a biasing member and/orinner cable 402.FIG. 3A illustratesdeflector 500 in a most “open” position such as when control member 202 (FIG. 1 ) is in its most rearward position along line R (FIGS. 1 , 4A, 4B) with respect to controldevice 200, or disposed closer in distance towards the U-shaped end portion of machine handle MH (FIG. 1 ). The most “open” position can correspond to a maximum angle α being disposed betweendeflector 500 and horizontal axis H. Angle α can generally range from approximately 0° (fully closed) to approximately 45° or more. In some aspects, angle α can be more than 45°, such as between approximately 45° and approximately 90°. The maximum angle or a fullyopen deflector 500 can vary by deflector shape and/or deflector design. Opening or raisingdeflector 500 to a fullest extent by a maximum amount produces the highest trajectory of a thrown snow stream. -
FIG. 3B illustratesdeflector 500 in a most “closed” position such as when control member 202 (FIG. 1 ) is in is most forward position along line F (FIGS. 1 , 4A, 4B) with respect to controldevice 200, or disposed closer in distance towards housing H and chute C of snowblower. Closing or loweringdeflector 300 by pivoting towards horizontal axis X can lower the trajectory of the thrown snow stream. In some aspects, the most “closed” position corresponds to when angle α is between approximately 0° and 5° with respect to horizontal axis X. - As
FIGS. 3A and 3B illustrate,deflector 500 can be disposed over a portion of chute C and hingedly mounted thereto.Deflector 500 can pivot about hinge a 502 as indicated by the double sided arrows, and can increase or decrease in angle α from horizontal axis X. The amount by which deflector 500 pivots can be controlled viacontrol device 200 and linkingmember 400 of system 100 (FIG. 1 ) and can be controlled by movingcontrol member 202 within discrete positions of a guide plate 208 (FIGS. 4A/4B). Whendeflector 500 is fully raised such as inFIG. 3A , the trajectory of the snow stream is maximized. Whendeflector 500 is fully closed, such as inFIG. 3B , the trajectory of the snow stream is minimized and/or the flow of snow from chute C is prohibited or blocked via a portion ofdeflector 500. Notably,guide plate 208 comprises a longitudinal body or longitudinal shaft that is longitudinally disposed with respect to a portion of machine handle MH. - The pivoting and/or fore/aft movements (e.g., along lines R and F,
FIG. 1 ) ofcontrol member 202 ofcontrol device 200 allow a user to selectively increase or decrease tension ofcable 402 by various amounts and induce pivotal movement ofdeflector 500. AsFIGS. 3A and 3B illustrate,outer sheath 404 of linkingmember 400 can be fixedly held at a first bracketedtab portion 504. Flexibleinner cable 402 of linkingmember 400 can be movable within fixed portion ofouter sheath 404 and can at least partially extend therefrom.Inner cable 402 can extend to asecond tab portion 506.Inner cable 402 can be fixedly held within a portion ofsecond tab portion 506.Outer sheath 404 can be fixedly held and remain stationary atfirst tab 504 allowing inner cable to flex between portions of first andsecond tab portions deflector 500 abouthinge 502.Inner cable 402 can be spaced apart fromhinge 502, and can be spaced apart from and fixedly held at a different portion ofdeflector 500 than biasingmember 508. -
Biasing member 508 can be fixedly held between portions of a first hingedprojection portion 510 and ahook portion 512.Projection portion 510 can be disposed proximate a center ofdeflector 500. Portions of biasingmember 508 can expand or extend and/or retract or contract in response to relative movement ofinner cable 402. In one aspect, biasingmember 508 can comprise a tension spring adapted to extend and retract for allowing portions ofdeflector 500 to pivot abouthinge 502 and about portions of chute C. -
Biasing member 508 can also maintain an amount of tension acrossinner cable 402 such thatcable 402 does not become substantially slack.Control member 202 can then be moved forwardly along line F (FIGS. 1 , 4A, 4B) and/or pivoted clockwise about a pivot point P (FIG. 4B ) to increase the amount of tension oncable 402 which in turn can extend biasingmember 508 andpivot deflector 500 downwardly. In further aspects,control member 202 can be moved rearwardly along line R (FIGS. 1 , 4A, and 4B) and/or pivoted counterclockwise about pivot point P (FIG. 4B ) to decrease or relax the amount of tension andpivot deflector 500 upwardly. -
Biasing member 508 can allowdeflector 500 to pivot abouthinge 502 when tension is increased toinner cable 402 via moving control member 202 (FIG. 1 ) in a first direction or when tension is decreased toinner cable 402 via movingcontrol member 202 in a second, opposite direction. That is, asinner cable 402 flexes or pulls in response to forward movement F (FIG. 1 ) of control member 202 (FIG. 1 ) in a first direction, inner cable can expand, extend, orstretch biasing member 508 and causedeflector 500 to pivot downwardly (e.g., decrease angle α). Conversely, as tension is released frominner cable 402 in response to rearward movement R (FIG. 1 ) ofcontrol member 202 in a second direction,inner cable 402 can retract biasingmember 508 and causedeflector 500 to pivot upwardly (e.g., increase angle α). - Still referring to
FIGS. 3A and 3B , movement of control member 202 (FIG. 1 ) induces movement of flexibleinner cable 402 of linkingmember 400, which in turn induces movement of biasingmember 508 ofdeflector 500. For example, as control member 202 (FIG. 1 ) ofcontrol device 200 moves towards a most forward position (e.g., toward afirst end 208′ of aguide plate 208,FIGS. 4A and 4B ) tension toinner cable 402 increases asinner cable 402 becomes pulled. This can cause biasingmember 508 to extend and/or assume an extended position.Deflector 500 can lower, angle α can decrease, and the trajectory of blown snow stream can be lowered. In a similar manner, movingcontrol member 202 rearwardly (e.g., towards asecond end 208″ ofguide plate 208,FIG. 4A ) decreases tension to flexibleinner cable 402 thereby allowing biasingmember 508 to relax or retract from the extended position and increase angle α betweendeflector 500 and horizontal axis X. - As biasing
member 500 moves between extended and retracted positions,deflector 500 can pivot abouthinge 502.Deflector 500 can be locked in any desirable position with respect to chute C such that the trajectory of snow can be maintained when so desired. Regardless of the specific configuration, biasingmembers biases deflectors deflectors control member 202 and/orinner cable 402. -
FIGS. 4A and 4B are perspective side views illustrating various aspects and features ofcontrol device 200. Referring toFIG. 4A ,control device 200 can comprise amovable control member 202.Control member 202 can comprise agrip portion 204 and aguide portion 206.Guide portion 206 can comprise a projection or tab adapted to move within and/or engage portions ofguide plate 208.Guide portion 206 can be longitudinally disposed along a longitudinal body portion ofcontrol member 202.Guide portion 206 can comprise a projection or tab configured to engage one or more slots ofguide plate 208. -
Guide plate 208 can comprise afirst end 208′ and asecond end 208″.First end 208′ can be disposed closer to housing H of snowblower SB.Second end 208″ can be disposed closer to U-shaped portion of machine handle MH, and closer to the user. Movingcontrol member 202 towardsfirst end 208′ can correspond to forward movement along line F with respect to U-shaped portion of machine handle MH (FIG. 1 ) and with with respect to guideplate 208. Movingcontrol member 202 towardssecond end 208″ can correspond to rearward movement along line R, back towards U-shaped portion of machine handle MH (FIG. 1 ) and/or rearward withinguide plate 208. -
Guide plate 208 can comprise acontoured profile 210 adapted to be positioned at least partially around an external surface of machine handle MH.Guide plate 208 can be adapted to receive a portion ofcontrol member 202. In one aspect,guide plate 208 can comprise a plurality of slots generally designated 212 or gates disposed betweenfirst end 208′ andsecond end 208″. The plurality ofslots 212 can comprise a plurality of gates disposed at regularly spaced intervals formed between a plurality of regularly spaced and integrally formedretention portions 214 or toothed portions ofguide plate 208. Notably, movingcontrol member 202 to adjacent gates orslots 212 betweenfirst end 208′ towardssecond end 208″ can decrease tension on cable 402 (FIG. 2A ). This can incrementally retract biasing member 308 (FIG. 2A ) and increase angle α (FIG. 2A ). Thus,deflector 300 can be incrementally raised upward (e.g., pivot upwardly) to increase the trajectory of the thrown snow. - Conversely, moving
control member 202 between gates orslots 212 fromsecond end 208″ towardsfirst end 208′ can pull or increase tension applied to inner cable 402 (FIG. 2B ) which in turn can extend biasingmember 308. Thus, movingcontrol member 202 between adjacent gates or slots 12 fromsecond end 208″ tofirst end 208′ (e.g., movingcontrol member 202 forward) can incrementally decrease angle α between a portion ofdeflector 300 and a horizontal axis X (FIG. 2A ), and can incrementally lower deflector 300 (e.g., pivot downwardly) to decrease the trajectory of the thrown snow. Notably,control member 202 can be moved to non-adjacent gates orslots 212 between first and second ends 208′ and 208″, respectively. Movingcontrol member 202 can responsively increase or decrease tension applied to portions of inner cable 402 (FIGS. 2A and 2B ). This, in turn, can move biasingmember 308 between extended and retracted positions thereby pivotingdeflector 300. Notably,control member 202 can be conveniently located and can be operable without needing power from an electric motor. -
Guide portion 206 ofcontrol member 202 can comprise a protrusion and/or protruding portion or flange adapted to engage at least oneslot 212 of the plurality ofslots 212. That is,guide portion 206 ofcontrol member 202 can be adapted or configured to substantially fit within a portion of at least oneslot 212 and become fixedly held adjacent to and/or between at least one retention portion of the plurality ofretention portions 214.Guide portion 206 can be fixedly held within at least oneslot 212, which can lockinner cable 402 in a fixed position thereby locking the angle α at which deflector is pivoted with respect to discharge chute C and/or horizontal axis X. -
Guide plate 208 comprising the plurality ofretention portions 214 andslots 212 or gates betweenretention portions 214 can advantageously be disposed outside and/or external from machine handle MH. This can be advantageous, as it provides a novel visual aspect of deflector control. That is, the user can actively select and choose discrete increments by which deflector 300 can be pivotably adjusted. This aspect can further allow a user to completely open orclose deflector 300 by movingcontrol member 202 between extreme ends ofguide plate 208 without having to move between each incremental position. A user can visually choose an amount by which to pivotdeflector 300 by visually externally disposed gates or slots ofcontrol device 200. By lockingcontrol member 202 between a selected one ofslots 212 orretention portions 214,deflector control system 100 can exert and maintain a uniform force upon biasing member 308 (FIGS. 2A and 2B ) that urges and/or locks deflector 300 in a desired position. - The number and/or spacing of
slots 212 can be selected to correspond to a number of desired pivotal positions for snowblower deflector 300 (FIGS. 2A and 2B ) and a desired angular displacement between adjacent positions. Specifically, as shown inFIG. 4A , for example,guide plate 208 can define sevenslots 212 so thatcontrol member 202 can move between seven discrete positions.Guide plate 208 can be provided with more or less than sevenslots 212 as those having skill in the art will recognize that any number ofslots 212 can be provided depending on the desired number of pivotal positions for deflector 300 (e.g., between approximately 0° and 90°). Moreover, eachretention portion 214 disposed betweenadjacent slots 212 can comprise a chamfered edge or profile which can provide for easier transition betweenslots 212. The spacing betweenadjacent retention portions 214 can be designed to establish substantially similar angular increments. The width of eachretention portion 214 can provide for regular, incremental angular displacement along angle α from a completely open to a completely closed position of deflector 300 (FIGS. 2A and 2B ). - As
FIG. 4A further illustrates,guide plate 208 can be fixedly held to a portion of machine handle MH via one or more attachment members or attachment devices. For example, attachment members can comprise afirst bolt 218 and afirst nut 228 assembly.Guide plate 208 can also be connected to a portion ofcontrol member 202 via at least one other attachment member, for example, asecond bolt 220 and asecond nut 222 assembly. First andsecond bolts more fastening members 242 can also be provided for attaching one or more portions ofguide plate 208 to one or more portions of aguide plate housing 216 as described further below with respect toFIG. 5 . - Still referring to
FIG. 4A , to control upward and/or downward motion of deflector 300 (FIGS. 2A and 2B ),control member 202 can be pushed outwardly (e.g., outward laterally), towards an outside of snowblower SB in a first direction D1. This will releaseguide portion 206 ofcontrol member 202 from arespective slot 212 and/or from betweenrespective retention portions 214 ofguide plate 208.Control lever 202 can then be moved forward or rearward (e.g., along lines F or R) and can pivot clockwise or counterclockwise about a pivot point P (FIG. 4B ).Control member 202 can be adjusted between one or more discrete positions which pivot or displace control member 300 (FIG. 2A ) by a discrete angle(s) or amount(s) by increasing or decreasing an amount of tension applied toinner cable 402. -
FIG. 4B is an opposing view ofcontrol device 200 inFIG. 4A , without guide plate housing 216 (FIGS. 4A and 5 ). AsFIG. 4B illustrates,guide plate 208 can physically couple or attach to controllever 202 via an attachment member such as a threadedbolt 220 andnut 222 assembly. As the double sided arrow indicates, nut andbolt control member 202 can pivot when moved forward and rearward. The forward movement ofcontrol member 202 along line F can increase an amount of tension oninner cable 402 by pullinginner cable 402 in a third direction D3. This increased tension can pivot or movedeflector 300 downward (FIG. 2B ). The rearward movement ofcontrol member 202 along line R can decrease and/or relieve or release an amount of tension oninner cable 402 by movinginner cable 402 in a fourth direction D4. Third and fourth directions D3 and D4 can be orthogonal to each of first and second directions D1 and D2 which releasecontrol member 202 from a respective gate orslot 212. This reduced tension can relax or retract biasingmember 308 and raise deflector 300 (FIG. 2A ). Notably,control member 202 can move generally in a first direction along lines R or F and in a second direction comprised of either and/or both directions D1 and/or D2, wherein the foreword/rearward movement along lines R or F is orthogonal to directions D1 and D2. - Accordingly, forward movement of
control member 202 along line F pivots a portion ofcontrol member 202 clockwise about pivot point P and can increase an amount of tension oninner cable 402 which in turn can lower deflector 300 (FIG. 2B ). Conversely, the rearward movement ofcontrol member 202 along line R can pivot a portion ofcontrol member 202 counterclockwise about pivot point P and can relieve an amount of tension oninner cable 402 and raise deflector 300 (FIG. 2A ). - As
FIG. 4B further illustrates, linkingmember 400 can comprise aboot 410 or boot assembly adapted to receive portions ofinner cable 402 andouter sheath 404. A portion ofboot 410 can be retained within a portion ofguide plate 208. Anend portion 406 ofinner cable 402 can be coupled to a lower portion ofcontrol member 202 such that the rearward, forward, and pivoting motions associated withcontrol member 202 can increase or decrease an amount of tension uponinner cable 402 to adjust a position or angle α at which deflector 300 (FIGS. 2A , 2B) is maintained. -

A plurality ofretention portions 214 can be disposed between afirst end 208′ and asecond end 208″ of guide plate forming a plurality ofslots 212 between which guideportion 206 ofcontrol member 202 can be fixedly held to lock deflector 300 (FIGS. 2A , 2B) at a certain angle α (FIGS. 2A , 2B) or position with respect to a horizontal axis.Retention portions 214 can be at least partially inclined or tapered to facilitate easier transition ofcontrol member 202 from oneslot 212 to another adjacent and/ornon-adjacent slot 212. - As described earlier,
control member 202 can be moved forward along line F and/or rearward along line R to lower or raise deflector 300 (FIGS. 2A , 2B).Control member 202 can be moved betweenadjacent slots 212 ornon-adjacent slots 212. Whencontrol member 202 is pivoted forward along line F to a selective one of the plurality ofslots 212, a portion ofcontrol member 202 can pivot or rotate clockwise about pivot point P (FIG. 4B ) and can increase an amount of tension applied toinner cable 402 of linkingmember 400. This can pivot deflector 300 (FIGS. 2A , 2B) downward by a selective amount. Moving control member rearward along line R can pivot a portion ofcontrol member 202 counterclockwise about a pivot point P (FIG. 4B ) and decrease an amount of tension applied toinner cable 402 of linkingmember 400. This can pivot deflector 300 (FIGS. 2A , 2B) upward by a selective amount. -
Control device 200 can comprise aguide plate 208 and aguide plate housing 216.Guide plate 208 can be disposed about a portion of a machine handle MH and can be visible to a user, such that the user can select an amount by which to pivotably open or close the deflector.Guide plate 208 can be affixed to a portion of machine handle MH via afirst bolt 218 andnut 228. Any other attachment member is contemplated.Guide plate 208 can be affixed to guideplate housing 216 via positioning one ormore fastening devices 242 through one or more openings orholes 244 ofguide plate 208 and securingfastening devices 242 intoopenings 246 ofguide plate housing 216. Fasteningdevices 242 can comprise a screw or any other suitable component for physically fastening or attaching bodies of material, such as a pin, nail, bolt, rivet, tape, adhesive, clip, hook, etc. - A lower or end portion of
control member 202 can comprise a first opening oraperture 226 by which a portion ofcontrol member 202 can be coupled to a portion ofguide plate 208. In one aspect, abolt 220 and anut 222 can be secured throughfirst aperture 226 ofcontrol member 202 and one ormore holes 244 ofguide plate 208. Any other type of attachment member other than abolt 220 andnut 222 is contemplated. Notably, a portion ofcontrol member 202 can rotate or pivot aboutbolt 220 andnut 222, such that together, bolt 220 andnut 222 form a pivot point P (FIG. 4B ). -
Control member 202 can also comprise a second opening oraperture 240 by which a portion ofcontrol member 202 can be coupled to an end portion orfirst end 406 ofinner cable 402.First end 406 can comprise afirst portion 406A, asecond portion 406B, and athird portion 406C which can be threaded and/or disposed about one or more portions ofcontrol member 202. For example,second portion 406B ofend portion 406 can be threaded throughsecond aperture 240 ofcontrol member 202 such that first andthird portions control member 202.Inner cable 402 can be disposed within a portion ofboot 410 and disposed in anouter sheath 404 retained byboot 410.Boot 410 can be retained within a portion ofguide plate 208. -
FIG. 6 is a sectional view ofcontrol device 200 along lines 6-6 ofFIG. 4A . For illustration purposes, guideplate housing 216 is not shown. AsFIG. 6 illustrates,guide plate 208 can be fixedly attached to machine handle MH via an attachment member, such as afirst nut 228 andfirst bolt 218 assembly.Guide plate 208 can further be attached to a portion ofcontrol member 202 via asecond nut 222 andsecond bolt 220 assembly.Control member 202 may not be affixed and/or coupled to machine handle MH. Twowashers 224 can optionally be disposed between portions ofcontrol member 202 and bolt 220 such thatcontrol member 202 can move in and out of slots 212 (FIG. 5 ) via moving between first direction D1 and second direction D2. Moving between first and second directions D1 and D2 can moveguide portion 206 or tab between one or more retention portions 214 (FIG. 5 ) ofguide plate 208. -
Control member 202 can also be coupled to a portion ofinner cable 402. For example, anend portion 406 of flexibleinner cable 402 can be disposed about one or more edges or surfaces ofcontrol member 202. For example, a lower portion ofcontrol member 202 can be disposed between afirst portion 406A and asecond portion 406C ofend portion 406 ofinner cable 402. - This written description uses examples to disclose the subject matter, including the best mode, and also to enable any person skilled in the art to make and use the subject matter herein.
