DETAILED DESCRIPTION
Referring to the drawings, wherein like numbers indicate the same or corresponding elements throughout the views, FIG. 1 illustrates a vehicle 10 that includes a control system, indicated generally at 12, according to one embodiment. Control systems according to the inventive principles can be used with an all terrain vehicle (ATV) such as vehicle 10 shown in FIG. 1, or with a variety of other saddle-type or other vehicles configured for recreational and/or utility purposes.
Vehicle 10 can include a pair of front wheels 14 and a pair of rear wheels 16 (one shown). Vehicle 10 includes a frame, indicated generally at 18. The front wheels 14 and rear wheels 16 can be suspended from frame 18 and are rotatable relative to frame 18. Vehicle 10 further includes a source of motive power 20, which can be an internal combustion engine, an electric motor or any other suitable source of motive power. The source of motive power 20 is drivingly connected to a drivetrain that is operable for transferring torque to the front wheels 14 and/or the rear wheels 16. The drivetrain can include a transmission 22 that can be driven by the source of motive power 20.
Vehicle 10 can further include a seat 30 suitable for supporting an operator of vehicle 10 and a handlebar assembly 32 configured for turning the front wheels 14 to steer vehicle 10. Handlebar assembly 32 can include a right handlebar 34 and a left handlebar 36. The right handlebar 34 can include a right hand grip 35 and the left handlebar 36 can include a left handgrip 37.
Vehicle 10 can also include a snow-plow 38 having a blade 40 and a pair of spaced arms 42 integral with the blade 40 and pivotably connected to corresponding links 44 (one shown) attached to frame 18. Vehicle 10 can also be configured to include a winch 50 having a housing 52 attached to frame 18, and a cable 54 attached to the blade 40 for selectively raising and lowering the blade 40. The blade 40 can be positioned in a lower, snow-plowing position (FIG. 1) and can be raised vertically to a disengaged position (not shown). Vehicle 10 can include a pair of foot rests 46 (one shown) and a foot brake lever 48 positioned adjacent one of the foot rests 46. The foot brake lever 48 can be coupled to a rear brake system (not shown) of vehicle 10 to apply a braking force to the rear wheels 16. A lever (not shown), which can be similar to the foot brake lever 48, can be provided on the other side of the vehicle 10 to facilitate shifting of gears within the transmission 22.
Control system 12 can include a winch control device 60 (FIG. 1), which can include a switch, push buttons, or any other suitable control device, which can be coupled to the left handlebar 36 as shown in FIG. 1. Control system 12 can also include a pair of hand levers, at least one of which can be a hand brake lever. For example, a hand brake lever 62a can be coupled to a front and/or rear brake system (not shown) of the vehicle 10. In one embodiment, a hand lever 62b can also be configured as a hand brake lever which can be coupled to a front and/or rear brake system of the vehicle 10. In another embodiment, the hand lever 62b can be configured as a clutch control lever and coupled with the transmission 22 of the vehicle.
Control system 12 can also include a throttle lever 64 that can be coupled to a fuel system component (not shown) of vehicle 10 and a reverse lever 66 that can be coupled to a drivetrain component of vehicle 10. For example, the reverse lever 66 can be coupled to the transmission 22 of vehicle 10 via various conventional means, such as a Bowden cable 68 (FIGS. 2, 3A and 3B). Various other cables that can be included in control system 12, with each being associated with one the winch control device 60, hand brake lever 62a, hand lever 62b and throttle lever 66, are not shown in FIGS. 1, 2, 3A and 3B for purposes of illustration. Use of the reverse lever 66 can, in one embodiment, enable selection of a reverse gear by an operator through use of a gear selection device, for example a foot-operated shift lever. In another embodiment, use of the reverse lever 66 can place the vehicle into a reverse gear. The hand brake lever 62a, the throttle lever 64 and the reverse lever 66 can each be pivotably coupled to the right handlebar 34. In another embodiment (not shown), a hand brake lever, a throttle lever and a reverse lever can each be pivotably coupled to a left handlebar of a vehicle and a winch control device can be connected to a right handlebar of the vehicle.
The control system 12 can also include a mount bracket 74 that can be connected to the right handlebar 34 as shown in FIGS. 1, 2, 3A and 3B. The hand brake lever 62a, the throttle lever 64 and the reverse lever 66 can be pivotably coupled to the mount bracket 74. In one embodiment, mount bracket 74 can include a ring member 75 connected to the right handlebar 34 and a plate 76 integral with the ring member 75. The plate 76 can engage a hydraulic reservoir 77 that can also be connected to the right handlebar 34 as shown in FIGS. 1, 2, 3A and 3B. However, it will be appreciated that a mount bracket can be connected to a handlebar in any of a variety of other suitable arrangements. One or more fluid conduits that can be associated with hydraulic reservoir 77 are not shown for purposes of illustration.
The hand brake lever 62a can be pivotable between a disengaged position shown in FIG. 3A and an engaged position shown in FIG. 3B about a pivot axis 78 (FIGS. 2, 3 and 4). The throttle lever 64 can be pivotable between a disengaged position shown in FIG. 3B and an engaged position shown in FIG. 3A about a pivot axis 80 (FIGS. 3A and 3B). The reverse lever 66 can be pivotable between a disengaged position shown in solid line in FIG. 3A and in dashed line in FIG. 3B, and an engaged position shown in solid line in FIG. 3B about a pivot axis 82 (FIGS. 2, 3 and 4). Pivot axes 78 and 82 can be parallel with one another as shown in FIG. 2. Pivot axis 80 might also be parallel with one or both of the pivot axes 78 and 82. As shown in FIGS. 3A and 3B, pivot axes 78, 80 and 82 can be spaced apart from one another. In another embodiment (not shown), a hand brake lever and a reverse lever can be provided that can pivot about a common axis.
The reverse lever 66 and the hand brake lever 62a can be configured and positioned relative to one another so that the reverse lever 66 is prevented from pivoting from the disengaged position to the engaged position when the hand brake lever 62a is in the disengaged position shown in FIG. 3A. In one embodiment, the reverse lever 66 can include a mount portion 85 that can be pivotably coupled to the mount bracket 74, a grasping portion 86 integral with the mount portion 85 and a tab 87, or other suitable protrusion, which is integral with the grasping portion 86. Tab 87 can be disposed in contacting engagement with the hand brake lever 62a when the hand brake lever 62a is in the disengaged position shown in FIG. 3A. The contacting engagement of tab 87 with the hand brake lever 62a prevents the reverse lever 66 from pivoting between the disengaged and engaged positions about pivot axis 82 until the hand brake lever 62a is pivoted from the disengaged position toward the engaged position. As shown in FIG. 3B, once the hand brake lever 62a is moved to the engaged position, and the reverse lever 66 is also moved to the engaged position, the tab 87 can again be in contacting engagement with the hand brake lever 62a.
FIGS. 4, 5A and 5B illustrate a portion of a control system according to another embodiment that can include a hand brake lever 162, a throttle lever 164 and a reverse lever 166. The hand brake lever 162, the throttle lever 164 and the reverse lever 166 can each be pivotably coupled to the right handlebar 34 as shown in FIGS. 4, 5A and 5B. The control system according to this embodiment can also include a winch control device, such as the winch control device 60 shown in FIG. 1, and can be used on vehicle 10 in lieu of the control system 12. The throttle lever 164 can be coupled to a fuel system component (not shown) of vehicle 10 and the reverse lever 166 can be coupled to a drivetrain component of vehicle 10 such as transmission 22 via various conventional means, such as a Bowden cable 168. Other cables that can be included in the control system according to this embodiment, with each being associated with one of the hand brake lever 162 and the throttle lever 164, are not shown for purposes of illustration. A second hand lever (not shown) can be provided for control of a brake or a clutch, for example, and can be associated with the left handlebar 36. In another embodiment, a throttle lever, a reverse lever and a hand brake lever can be pivotably coupled to the left handlebar of a vehicle, with a winch control device being connected to the right handlebar of the vehicle.
The hand brake lever 162, the throttle lever 164 and reverse lever 166 can be pivotably coupled to a mount bracket 174 that can be connected to the right handlebar 34 as shown in FIGS. 4, 5A and 5B. In one embodiment, the mount bracket 174 can include a ring member connected to the right handlebar 34 and a plate integral with the ring member. The plate of mount bracket 174 can engage a hydraulic reservoir 177 that can also be connected to the right handlebar 34 as shown in FIGS. 4, 5A and 5B. One or more fluid conduits that can be associated with the hydraulic reservoir 177 are not shown for purposes of illustration. The reverse lever 166 can include a mount portion 185 that can be pivotably coupled to the mount bracket 174, and a grasping portion 186 integral with the mount portion 185. The hand brake lever 162 can be pivotable between a disengaged position shown in solid line in FIGS. 4, 5A and 5B, and an engaged position shown in dashed line in FIG. 4, about a pivot axis 178. The throttle lever 164 can be pivotable between a disengaged position shown in FIGS. 4 and 5B, and an engaged position shown in FIG. 5A, about a pivot axis 180. The reverse lever 166 can be pivotable between a disengaged position shown in FIGS. 4 and 5A and an engaged position shown in FIG. 5B, about a pivot axis 182. The pivot axes 178 and 182 can be parallel with one another. Pivot axis 180 might also be parallel with one or both of the pivot axes 178 and 182.
The reverse lever 166 and the throttle lever 164 can be spaced apart by a distance “d1” that can be generally perpendicular to a line 190 that is generally tangent to the reverse lever 166 and that can also be generally perpendicular to a line 192 that is generally tangent to the throttle lever 164, as shown in FIG. 4. In FIG. 5A, a hand 200 of an operator of vehicle 10 is shown to be grasping the right hand grip 35 of the right handlebar 34, with a thumb 202 of hand 200 depressing the throttle lever 164 so that the throttle lever 164 is in an engaged position. As a result, vehicle 10 can be accelerated. Distance “d1” can be selected, i.e. the throttle lever 164 and the reverse lever 166 can be positioned relative to one another, so that the reverse lever 166 and the throttle lever 164 are sufficiently spaced apart to prevent an operator of vehicle 10 from moving the reverse lever 166 from the disengaged position to the engaged position and simultaneously moving the throttle lever 164 with a single hand, such as hand 200. For example, as shown in FIG. 5B, the thumb 202 of hand 200 must be disengaged from the throttle lever 164 to permit a forefinger 204 of hand 200 to engage (i.e., by grasping or pulling) the grasping portion 186 of the reverse lever 166. The reverse lever 166 and the hand brake lever 162 can be positioned in sufficient proximity to permit an operator of vehicle 10 to simultaneously engage the reverse lever 166 and the hand brake lever 162 with a single hand, such as hand 200, as shown in FIG. 5B.
When certain conventional all terrain vehicles are used for snow-plowing, a reverse lock out arrangement and a device used to control the height of the snow-plow blade, for example a winch controller, can be mounted on the same side of the vehicle, for example on the left side. This can result in wasted hand motion and can make shifting and simultaneous blade height adjustment difficult. This may be appreciated when considering the following typical sequence of operations during snow-plowing: plow snow with vehicle moving in a forward direction; stop vehicle; lift snow-plow blade; put vehicle in reverse gear and back up; lower snow-plow blade; put vehicle in forward gear; and repeat sequence as required.
Utilization of control systems according to the inventive principles can facilitate more efficient operation of all terrain vehicles used for snow-plowing. In particular, such control systems eliminate wasted hand motion and make simultaneous adjustment of the snow plow blade height and gear selection possible. Additionally, it can be achieved while preventing simultaneous engagement of the throttle and reverse levers. For example, as shown in FIGS. 1, 2, 3A and 3B, the winch control device 60 that can be included in control system 12 can be connected to one handlebar, for example the left handlebar 36, while each of the hand brake lever 62a, throttle lever 64 and reverse lever 66 can be pivotably coupled to the other handlebar, for example the right handlebar 34. This allows an operator of vehicle 10 to use one hand to raise and lower the blade 40 of snow-plow 38, while using the other hand to operate the hand brake lever 62a, the throttle lever 64 and the reverse lever 66. As described previously, it can be necessary to pivot the hand brake lever 62a from the disengaged position toward the engaged position before the reverse lever 66 can be engaged, thereby providing an interlock feature.
Similarly, in the control system shown partially in FIGS. 4, 5A and 5B, the winch control device 60 that can be included in this control system can be connected to one handlebar, for example the left handlebar 36, while each of the hand brake lever 162, the throttle lever 164 and the reverse lever 166 can be pivotably coupled to the other handlebar, for example the right handlebar 34. Accordingly, this control system also allows an operator of vehicle 10 to use one hand to raise and lower the blade 40 of snow-plow 38, while using the other hand to operate the hand brake lever 162, the throttle lever 164 and the reverse lever 166. The hand brake lever 162, the throttle lever 164 and the reverse lever 166 can be positioned relative to one another to prevent an operator of vehicle 10 from moving the reverse lever 166 from the disengaged position to the engaged position while simultaneously moving the throttle lever 164 with a single hand, but to permit simultaneous engagement of the reverse lever 166 and the brake lever 162 with a single hand. It will be appreciated that control systems according to the inventive principles can also provide advantages during other driving conditions (i.e., when not plowing) of all terrain vehicles or other vehicles.
While the inventive principles have been illustrated by the description of various embodiments thereof, and while the embodiments have been described in considerable detail, it is not intended to restrict or in any way limit the scope of the appended claims to such detail. Additional advantages and modifications will be readily apparent to those skilled in the art. The invention in its broader aspects is therefore not limited to the specific details, representative apparatus, methods and examples shown and described. Accordingly, departures may be made from such details without departing from the scope or spirit of the general inventive principles.
