Abstract
A walk-behind greensmower includes an operator presence control for selectively determining when power from a source is delivered to an output. The operator presence control includes a handle, a bale coupled to the handle, a control arm and an electromagnet. The bale is moveable between an engaged position and a disengaged position. The control arm is moveable between a neutral position and a drive position where the control arm causes delivery of power from the source to the output when in the drive position. The electromagnet is selectively energizable in response to the position of the bale such that the control arm is retained in the drive position when the bale is in the engaged position.
Description
- This application is a divisional of U.S. patent application Ser. No. 10/364,778 filed on Feb. 11, 2003. The disclosure of the above application is incorporated herein by reference.
- The present invention relates to a walk-behind greensmower and, more particularly, to an articulating handle and control system for a walk-behind greensmower.
- Walk-behind reel mowers and rotary mowers have been provided with operator presence features in the past. Typically, the mower is provided with a lever called a bale which may be moved between a disengaged and engaged positions. When the operator moves the lever to its engaged position, the traction mechanism, the blade or both are driven. If the operator releases the bale, the blade and/or traction mechanism are stopped.
- While the existing operator presence control mechanisms may operate sufficiently, it is desirable to provide a walk-behind reel mower with an operator presence control having a reduced number of components, simplified operation and improved reliability.
- A walk-behind greensmower includes an operator presence control for selectively determining when power from a source is delivered to an output. The operator presence control includes a handle, a bale coupled to the handle, a control arm and an electromagnet. The bale is moveable between an engaged position and a disengaged position. The control arm is moveable between a neutral position and a drive position where the control arm causes delivery of power from the source to the output when in the drive position. The electromagnet is selectively energizable in response to the position of the bale such that the control arm is retained in the drive position when the bale is in the engaged position.
- Another embodiment of the present invention includes a tilt mechanism pivotally interconnecting a handle and a support. The tilt mechanism is operable to selectively fix the position of a handle relative to the support at a desired angle.
- Further areas of applicability of the present invention will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.

- Referring to
FIG. 1 , a walk-behind reel mower constructed in accordance with the teachings of the present invention is depicted atreference numeral 10. Mower 10 includes acutting unit 12 and anoperator control assembly 14.Cutting unit 12 includes a power source orengine 15 coupled to aframe 16. Atraction roller 18 is rotatably coupled toframe 16 and drivingly connected toengine 15. Areel 20 includes a plurality ofblades 22 rotatably mounted toframe 16.Reel 20 is selectively driven byengine 15. Atransmission 24 includes a plurality ofsprockets 25 selectively transferring rotational output torque ofengine 15 totraction roller 18 and/orreel 20.Transmission 24 includes aclutch 26 positionedintermediate engine 15 andtransmission 24. Clutch 26 is operable in an engaged mode and a disengaged mode for selectively transferring power fromengine 15 totraction roller 18 andreel 20.Wheels 28 are coupled totraction roller 18 and are also selectively driven byengine 15 to provide motive force for translating walk-behindgreensmower 10 along the ground. It should be appreciated that while the operator control assembly of the present invention is shown in conjunction with a walk-behind greensmower powered by an internal combustion engine, other devices are contemplated. For example, any walk-behind device such as a blower, string trimmer or mower may incorporate the operator control assembly of the present invention. Furthermore, these devices may utilize electric motors, hybrid power sources or the like. - With reference to
FIGS. 2 and 3 ,operator control assembly 14 includes asupport arm 30, anactuation assembly 32, atilt mechanism 34 and ahandle assembly 36.Support arm 30 provides a substantially rigid structure for supportingactuation assembly 32 andtilt mechanism 34.Support arm 30 interconnects handleassembly 36 andframe 16 to allow an operator to control the direction of movement ofmower 10.Support arm 30 includes afirst end 37 and asecond end 38.First end 37 includes a pair of bifurcatedtubular legs 39 pivotally coupled toframe 16. The pivotal interconnection allows a user to rotate the entire operator control assembly about apivot axis 40 to account for variation in operator stature.Second end 38 provides a rigid mount fortilt mechanism 34. Asupport bracket 42 is coupled to supportarm 30 intermediatefirst end 37 andsecond end 38.Support bracket 42 provides mounting locations for a variety of components ofactuation assembly 32. Aguide sleeve 44, apivot pin 45, and acable bracket 46 are also coupled to supportarm 30 to provide a mount for components ofactuation assembly 32. -
Actuation assembly 32 includes acontrol arm 48 selectively positionable in a neutral position (shown inFIG. 2 ), a drive position and a brake position.Control arm 48 provides an operator a single interface for engaging and disengagingclutch 26 as well as for applying or releasing the brakes (not shown).Control arm 48 includes a substantially cylindricalfirst portion 50 and a substantially cylindricalsecond portion 52. Acam 54 is fixed tofirst portion 50. Cam 54 includes alower lobe 56 and anupper lobe 58.First portion 50 is rotatably supported withinguide sleeve 44. Acable link 60 is coupled to an end ofcontrol arm 48 such thatguide sleeve 44 is trapped betweencable link 60 andcam 54 to limit axial movement ofcontrol arm 48. Aclutch cable 62 is coupled to first end 64 ofcable link 60. A pair ofbrake cables 66 is pivotally coupled to a second end 68 ofcable link 60. Cable link 60 also includes apaddle 70 for engagement with anelectromagnet 72, as will be described in greater detail hereinafter. - A
pawl 74 is pivotally coupled topivot pin 45.Pawl 74 is selectively positionable in an engaged position as shown inFIG. 3 , and a disengaged position wherepawl 74 does not contactcam 54.Pawl 74 includes ahead 78 selectively engageable withcam 54 and afinger 80 positioned distally fromhead 78. Ayoke 82 is pivotally coupled topawl 74 and is configured to mount one end of acontrol cable 84 thereto. Aspring 85 partially surroundscontrol cable 84 and loads pawl 74 to biashead 78 into engagement withcam 54. - A micro-switch 86 is mounted to support
bracket 42 and is selectively actuated byfinger 80 ofpawl 74.Micro-switch 86 is normally open and in electrical communication with arectifier 88 andelectromagnet 72. During operation,rectifier 88 accepts an alternating current signal fromengine 15 and converts the alternating current signal into a direct current input to micro-switch 86. Whenfinger 80 contacts micro-switch 86, the circuit is closed to supply a DC signal toelectromagnet 72. - Handle
assembly 36 includes a handle 90, abale 92, atilt plate 94 and athrottle control 96.Bale 92 is pivotally coupled to handle 90 to provide an operator presence control.Bale 92 is rotatable from a disengaged position shown inFIG. 3 to a rearward engaged position wherebale 92 contacts handle 90.Bale 92 is a substantially closed loop wire-form having a substantiallycylindrical base leg 98. Astop 100 is rigidly coupled tobase leg 98 and inwardly protrudes therefrom. Stop 100 includes adetent 102 for receipt of the opposite end ofcontrol cable 84.Spring 85 provides a biasing force oncontrol cable 84 such thatbale 92 is biased to the disengaged position. - As shown in
FIGS. 4 and 5 ,tilt plate 94 includes ajournal 104 to rotatablysupport base leg 98.Tilt plate 94 also includes apocket 106 for receipt ofstop 100. The articulation angle ofbale 92 toward the disengaged position is limited by the size ofpocket 106. Specifically, stop 100 contacts tiltplate 94 after it has rotated through the clearance provided bypocket 106. - Handle 90 includes an integrally molded
base 108.Base 108 includes a mountingsurface 110,journals 112 andbosses 114.Journals 112 cooperate withjournal 104 oftilt plate 94 to capturebase leg 98 ofbale 92 while providing rotational freedom to the bale. - Threaded fasteners 116 extend through
apertures 118 oftilt plate 94 tocouple tilt mechanism 34 tobase 108 of handle 90.Additional fasteners 120 extend throughapertures 122 oftilt plate 94 to couple the tilt plate tobase 108.Throttle control 96 is mounted tobosses 114 to provide a conveniently located adjustable throttle adjacent the operator's hands. - With reference to
FIG. 6 ,tilt mechanism 34 includes anupper bracket 124 pivotally coupled to alower bracket 126. Alever 128 is pivotally coupled toupper bracket 124 and is rotatable to selectively placetilt mechanism 34 in a locked or unlocked mode. Aspring 130 biases lever 128 toward a first position corresponding to the locked mode.Upper bracket 124 is a substantially “C” shaped member having a base 132 and a pair ofside walls 134.Base 132 includes a plurality ofapertures 136 extending therethrough for receipt of fasteners 116. -
Lower bracket 126 is also a substantially “C” shaped member having a base 138 and a pair ofside walls 140. Each ofside walls pin 142 to pivotally interconnectupper bracket 124 tolower bracket 126. -
Lever 128 includes abody 144, atang 146 and a pair ofvertical supports 148 downwardly extending frombody 144.Tang 146 extends outwardly beyond the upper and lower brackets to provide a surface which may be easily grasped by an operator. A plurality ofteeth 150 are positioned at an end of at least one ofvertical supports 148. A pair of reinforcingplates 154 is coupled to an inner surface ofside walls 140 oflower bracket 126. A plurality ofteeth 156 are positioned on the distal end of at least one of reinforcingplates 154.Teeth 156 are normally positioned in meshing engagement withteeth 150 due to the biasing force supplied byspring 130. When the two sets of teeth are engaged, the angular position of handle 90 is fixed. If an operator wishes to tilt handle 90,lever 128 is rotated about anaxis 158 to disengageteeth 150 fromteeth 156. Once the teeth are disengaged, the operator may rotate handle 90 to a desired position. By providing this adjustment feature, operator fatigue and discomfort should be minimized. A shroud 160 (FIG. 2 ) is placed overupper bracket 124 andlever 128 to limit ingress of contaminants and operator appendages within the area defined betweenupper bracket 124 andlower bracket 126. - In operation,
engine 15 is started and an electrical AC signal is supplied torectifier 88.Rectifier 88 converts the AC signal into a DC signal which is supplied tomicro-switch 86.Micro-switch 86 is normally open and current is not supplied to electromagnet 72 at this time. If an operator wishes to drivetraction roller 18 and/or reelassembly 20,bale 92 is rotated rearwardly to the engaged position. Rotation ofbale 92 causes stop 100 to rotate and impart tension to controlcable 84.Control cable 84 causes pawl 74 to rotate thereby disengaginghead 78 fromlower lobe 56 ofcam 54. Aspawl 74 is rotated,finger 80 closes micro-switch 86 to provide a DC signal toelectromagnet 72. - At this time,
control arm 48 is rotated toward cuttingunit 12.Paddle 70 engages anupper surface 162 ofelectromagnet 72 thereby limiting the maximum rotation ofcontrol arm 48. Acoupling 164pivotally interconnects electromagnet 72 andsupport bracket 42. Aspring 166 positions electromagnet 72 in a substantially vertical orientation. However,spring 166 also allowselectromagnet 72 to move viacoupling 164 whenpaddle 70 comes into contact withsurface 162 thereby providing optimum alignment between the paddle and the electromagnet. During rotation ofcontrol arm 48, a tensioning force is imparted toclutch cable 62.Clutch 26 is shifted to its engaged mode where drive torque is supplied fromengine 15 totraction roller 18 andreel assembly 20. - Because
electromagnet 72 is energized and paddle 70 is constructed from a ferro-magnetic material,control arm 48 is retained in a position to engage clutch 26.Clutch cable 62 is biasedly loaded in a direction to urgecontrol arm 48 to the neutral position but the torque generated byelectromagnet 72 andpaddle 70 is greater than the torque provided byclutch cable 62. Therefore, the operator need not continue applying force to controlarm 48 onceclutch 26 is engaged. - The operator presence control functions to discontinue the supply of power from
engine 15 totraction roller 18 andreel assembly 20 ifbale 92 is released. Whenbale 92 is released,spring 85 urges pawl 74 to rotate. During rotation ofpawl 74,head 78 engagesupper lobe 58 ofcam 54 andfinger 80 becomes spaced apart frommicro-switch 86.Micro-switch 86 opens and discontinues supply of power toelectromagnet 72. Onceelectromagnet 72 is shut off,cable link 60,cam 54 andcontrol arm 48 rotate away from cuttingunit 12 toward the neutral position due to the return spring load provided byclutch cable 62.Control arm 48 tends to remain in the neutral position because at least one ofbrake cables 66 also includes a return spring counteracting the clutch cable return spring load. Oncecontrol arm 48 is rotated to the neutral position,head 78 ofpawl 74 engagedlower lobe 56 ofcam 54 to provide a lock-out feature. Whenbale 92 is in the disengaged position,control arm 48 is locked-out from rotating toward cuttingunit 12 byhead 78. In this manner,traction roller 18 andreel assembly 20 may not be actuated without an operator present to maintainbale 92 in its engaged position. - Braking may be accomplished by rotating
control arm 48 away from cuttingunit 12. One skilled in the art will appreciate thatbale 92 need not be rotated into the engaged position to actuate the brakes. Ascontrol arm 48 is rotated,cable link 60 imparts a tensile force to brakecables 66, thereby actuating the brakes. Furthermore,cable link 60 may continue to be rotated such that anattachment pin 168 ofbrake cables 66 is moved to an over-center position, thereby providing a parking brake function. The range of motion in the over-center direction is limited bypaddle 70 contactingpivot pin 45. When in the over-center position, both brakes remain applied after the force to controlarm 48 has been removed. The brakes may be released by simply rotatingcontrol arm 48 to the neutral position. -
FIG. 7 depicts an alternateoperator control assembly 200 including afirst micro-switch 202, a second micro-switch 204, arelay 206 and anelectromagnetic clutch 208. The micro-switches and electromagnetic clutch are used in lieu of the previously described clutch, control cable assembly and electromagnet. Specifically,first micro-switch 202 is normally open and is closed upon movement ofbale 92 to the engaged position. Oncefirst micro-switch 202 is closed, current is supplied to relay 206. Whencontrol arm 48 is rotated toward cuttingunit 12, cable link 60 contacts second micro-switch 204 in a momentary fashion to latchrelay 206. The latching ofrelay 206 causes current to flow toelectromagnetic clutch 208 whenfirst micro-switch 202 is closed, thereby placingelectromagnetic clutch 208 in an engaged mode.Electromagnetic clutch 208 is maintained in the engaged mode as long asbale 92 is positioned in the engaged position andfirst micro-switch 202 is closed. Ifbale 92 is released to the disengaged position,first micro-switch 202 opens and discontinues the supply of current toelectromagnetic clutch 208 thereby de-couplingengine 15 andtraction roller 18. - Furthermore, the foregoing discussion discloses and describes merely exemplary embodiments of the present invention. One skilled in the art will readily recognize from such discussion, and from the accompanying drawings and claims, that various changes, modifications and variations may be made therein without department from the spirit and scope of the invention as defined in the following claims.
