Definitions

  • Walk-behind compaction rollers are used to compact soil and asphalt in order to provide a firm foundation for structural building, to reduce future settlement of soil, or to compact asphalt for pathway, road, and parking lot construction.
  • Such machines are commonly controlled by a single operator who follows behind the machine to direct the machine's travel direction and actuate its vibration control(s).
  • a control arm extends rearwardly from the machine and provides the mechanical advantage to allow the operator to physically manipulate the direction of travel of the machine.
  • Such machines may have one drum (single-drum) or two (dual-drum) drums acting as compaction surface(s).
  • One method to control the speed and direction (forward and/or rearward) of such machines is with a control lever that is supported at a rearward end portion of the control arm and whose position relative to the control arm actuates forward and reverse self-propelled travel of the machine.
  • a control lever that is supported at a rearward end portion of the control arm and whose position relative to the control arm actuates forward and reverse self-propelled travel of the machine.
  • such machines can be steered with a lateral force applied to the control arm to effectuate turning of the machine.
  • a spring force returns the control lever into the neutral position, and the machine ceases all travel.
  • Such machines are also commonly provided with a button or plunger that is disposed on a rearward distal end of the control arm and which interacts with the control associated with manipulation of the control lever. Depression of the button from behind the machine can suspend travel of the rolling machine altogether or at least prevent rearward propulsion of the machine while permitting forward propulsion. Such a configuration prevents an operator from being pinned between the machine and an obstacle behind the machine.
  • control arm is set to obtain leverage sufficient to allow a single operator to turn the machine by imparting lateral directional forces of a manageable magnitude to the control arm.
  • compaction roller In addition to the physical interaction of the operator with the control arm and the control lever, desired operation of the compaction roller requires the operator be able to readily visually inspect the operating environment to assess the speed and direction of travel relative to, for instance, areas already compacted, obstructions such as trench walls, other personnel, equipment, grade stakes or markings, already set formwork, etc. Because the rearward orientation of the control arm and control lever places the operator in a position that is substantially directly behind the compaction roller, the compaction roller can substantially hinder the operator's ability to visually inspect the operating environment.
  • Fig. 24 a visible area is denoted by lines 30 relative to the underlying compaction roller 32.
  • a visible area is denoted by lines 30 relative to the underlying compaction roller 32.
  • Such a configuration requires the operator to frequently reposition his body relative to the control arm 34 and the control lever 36 in order to achieve a desired orientation required to visually inspect the longitudinal edges 38 that extend along generally opposite lateral sides of the underlying compaction roller 32.
  • the position and orientation of the control lever relative to the control arm of many manually steered compaction rollers are ill-suited to allow the operator to attain various operating positions relative to the control arm and the control lever to provide the desired physical interaction with both the control arm and the control lever. They also provide for only limited positional association of the operator relative to the control arm to improve the visibility associated with operation of the compaction roller while maintaining a desired interaction of the operator with the control arm and the control lever. That is, the operators of such devices must commonly shuffle their left and right hands into and out of interaction with the control lever and/or the control arm or control handles to achieve the desired visibility and operator physical positioning with respect to the compaction roller controls to achieve the desired changes to the operating status and direction of travel of the compaction roller.
  • FR 2 355 122 A1 discloses a compaction roller having a control arm on which a control lever and a safety lever are provided. Backward movement of the safety lever is restricted by a handle of the control arm. The safety lever interacts with the control lever such that also backward movement of the control lever beyond a predetermined position is restricted.
  • Figs. 1-20 are various views of a control arrangement of a manually steered compaction roller according to one embodiment of the invention.
  • Figs. 21-23 show alternate embodiments of the invention that achieve the same benefits as disclosed with respect to the following description of Figs. 1-20 .
  • the various embodiments are encompassed by the scope of the appended claims.
  • Fig. 1 shows a compaction roller 40 having a control arm 42 that may be pivotably and/or removably connected to a frame 44 of the compaction roller 40.
  • Compaction roller 40 includes an engine 46 and a hydraulic system 48 associated therewith.
  • Engine 46 can be provided in various configurations such as electric start, pull start, and crank start configurations.
  • compaction roller 40 is provided with a crank handle 47 ( Fig. 2 , Fig. 5 ) configured to be removably associated with a crankshaft associated with engine 46 for initiating the first combustion compression cycle and thereby manual starting of engine 46.
  • Crank handle 47 removably cooperates with control arm 42 such that the orientation shown in Fig. 2 is associated with a storage position of crank handle 47 relative to compaction rollers 40 equipped with a crank start feature. Understandably, crank handle 47 need not be provided with compaction rollers having electric start and/or recoil start engine configurations.
  • a first drum 50 and a second drum 52 of compaction roller 40 are supported by frame 44 and constructed to compact the ground surface 54 associated with movement of compaction roller 40.
  • drums 50, 52 can be directly or indirectly excitable so as to enhance the compaction performance associated with operation of compaction roller 40.
  • an eccentric weight may be located on a lower portion of frame 44 between the two drums 50 to vibrate both drums 50 and 52.
  • the upper portion of the frame may be vibrationally isolated from the lower portion by shock mounts or the like.
  • At least one drum, and possibly both, is bi-directionally drivable to propel the compaction roller back and forth or in a forward and a rearward direction relative to the supporting ground surface.

  • dimension 63 an exemplary dimension or distance 63 is shown in the drawings, it is appreciated that the length of control arm 42 can be selected to improve the mechanical advantage associated with manual turning during operation of compaction roller 40. It is appreciated that a greater distance between compaction roller 40 and operator area 60 will increase the mechanical advantage associated with control arm 42, whereas shorter distances will require the operator to impart greater forces to control arm 42 to yield comparable turning performance than associated with longer control arms.
  • control arm 42 can be pivotably connected to compaction roller 40 to be settable at various elevations to accommodate operators of different heights and/or provide different positions of the operator area 60 to suit different operator preferences - such as the control area being positioned at a hip height or rib height as different operators may prefer or different operational situations may require.

  • control lever 64 cooperates with a push-pull cable 74 associated with generating forward and rearward linear operation of compaction roller 40 as a function of the orientation of control lever 64 relative to control arm 42.
  • control lever 64 is biased to a neutral position associated with suspending propulsion of compaction roller 40 in either the forward or the rearward directions.
  • push-pull cable 74, or any other suitable linkage can be provided in any of a number of suitable configurations for communicating instructions associated with the orientation of control lever 64 to the underlying compaction roller 40.
  • push-pull cable 74 and/or the control lever 64 can be configured to manipulate any of a number of operational systems, such as a hydraulic system or an electrical system associated with generating the desired forward, rearward, and neutral or non-moving operation of compaction roller 40. It is further appreciated that control lever 64 and/or the push-pull cable 74 can be configured to interact with various systems, such as relays, valves, etc., associated with generating the desired manipulation of the underlying operation of compaction roller 40.

  • the exciter control 70 and throttle control 71 can be configured to maintain a desired operation of the respective exciter and/or throttle associated with the underlying engine 46 without sustained operator interaction with the respective exciter control 70 and/or throttle control 71.
  • exciter control 70 and/or throttle control 71 be provided with a push-pull cable, elongated connector, gears, transmission, fluid system, relays, valves, etc. and/or an electrical system to effectuate communication of the exciter operation instructions and/or discrete throttle control instructions from operator area 60 to the respective underlying exciter and throttle systems of roller 40.
  • exciter control 70 is positioned nearer push button 72 than throttle control 71 as many users prefer to more commonly adjust operation of the exciter assembly than manipulate the throttle position during operation of compaction roller 40.

  • control lever 64 rotates about a pivot axis 86, thereby manipulating the orientation of cable 74 to achieve the desired change in the operating condition of compaction roller 40.
  • the control lever 64 is directly or indirectly biased to its neutral position such as, for example, by a spring acting on a pump control lever (not shown) to which the cable 74 is connected so that forward/rearward operation of compaction roller 40 is suspended whenever the operator releases control lever 64.
  • the push-pull cable 74 preferably is coupled to the hydraulic pump or other propulsion system of the compaction roller 40 such that the compaction roller 40 is propelled at a speed that is generally proportional to the extent of movement of the control lever 64 relative to its the neutral position.

  • the operator can stand beside control arm 42 while maintaining engagement with one or more of grip site 140, 142 and/or knob 126. Achieving such an orientation improves the operator's ability to view a respective lateral edge 38 ( Fig. 24 ) of compaction roller 40. It also allows the operator to orient himself in a manner that improves his leverage when turning the compaction roller 40. That is, operating the compaction roller from beside the control arm 42 rather than from directly behind it allows the operator to better use his mass rather than simply the strength of his arms and torso to effectuate the steering operation.
  • button 72 includes a stem or shaft 184 that is constructed to selectively interfere with rearward operation of compaction roller 40.
