Definitions
- the present invention relates to the field of floor treatment machines for scrubbing, polishing, sanding or burnishing floors.
- floor treatment machines for scrubbing, polishing, sanding or burnishing floors.
- one or more driven rotatable work heads (such as scrubbing brushes) are provided for agitating the floor surface.
- the invention relates to a walk-behind machine provided with a handle for steering and guiding the machine as it travels over a floor surface.
- EP2832277 discloses a walk-behind wet floor scrubber have two side- by-side work heads, each comprising disc-shaped floor brushes. There is a trailing squeegee and associated suction drive and reservoir for collecting liquid from the floor surface. The brushes support the weight of the machine and counter-rotate to provide propulsive force.
- the suction drive is disposed on a handle portion of the machine, along with a clean water reservoir for feeding a cleaning-liquid dispenser.
- the hand has dual pivot axes permitting up/down handle movement as well as side-to-side. A problem with these machines is that when not in use the elongate handle should be conveniently secured vertically against movement in the two axes, without having to be leant against another object.
- the present invention seeks to provide a handle immobilisation mechanism which is effective for securing floor treatment machine handles against handle pivoting, whether in one axis or two axes.
- a walk-behind floor treatment machine comprising:
- a base portion provided with and supported by at least one rotatable work head for treating the floor
- a handle portion for steering or guiding the machine along a working direction of travel and adapted to be pivotable with respect to the base portion
- drive means for rotating the work head with respect to the base portion, floor-engaging wheel means for supporting the handle portion, the wheel means having a substantially transverse axis of rotation so as to permit travel in the working direction, the wheel means being coupled to the base portion by a linkage which permits vertical travel of the base portion and associated work head or heads with respect to the wheel means, but which provides transverse constraint to limit or prevent yawing of the base portion with respect to the wheel means.
- a lower region of the handle portion may be pivotably connected to the wheel means via an articulated joint, the arrangement being such that the handle portion may be manipulated to act on the wheel means so as to yaw steer the wheel means about a yaw axis defined by the floor-engaging contact of the wheel means, the yawing of the wheel means causing the base portion to yaw in response to yaw steering.
- a handle pivot lock mechanism may be provided in which the adoption of a
- predetermined handle portion orientation permits one or more locking feature to act on one or more corresponding constraint feature so as to prevent pivoting movement of the handle portion with respect to the base portion.
- the predetermined handle orientation is preferably a vertical, or substantially vertical, orientation.
- the locking feature preferably becomes aligned with the constraint feature so as to permit mutual engagement. Conversely, when the orientation is not achieved misalignment prevents engagement of the features.
- the locking feature or features may be one or more detent feature and the constraint feature or features are one or more indent feature.
- One of said features may be associated with the base portion or linkage, and the other of said features may be associated with the handle portion.
- the pivoting of the handle may (at least) be up/down pivoting about a transverse axis, and the features may act to secure the handle portion against pivoting with respect to the transverse axis.
- a user-operable lock-mechanism actuator is preferably provided which must be operated to allow the locking and constraint features to act on each other. This actuator may then be operated to unlock the features so as to release the handle portion.
- the wheel means may comprise a wheel, roller or ball, preferably a single wheel, roller or ball, disposed at a lower region of the handle portion.
- the wheel means preferably has a fixed transverse axis of rotation.
- the linkage comprises at least one strut, one end region of which is provided with a pitch pivotal connection to the wheel means, which connection is coaxial with the wheel means axis of rotation, and wherein an other end region of the strut is attached to the base portion.
- the strut may be provided with a convex upper surface provided with the indent feature.
- the detent feature may be connected to a lower region of the handle portion for travel in an arc which corresponds to the profile of the convex upper surface, the arrangement being such that the detent feature can slide over the convex surface during up/down pivoting of the handle portion about the transverse axis.
- a lock actuator may be provided to displace or urge the detent feature against the surface so when the detent feature and indent feature are aligned the detent feature projects into the indent so as to lock motion of the handle portion.
- struts disposed on either side of the wheel means in a generally parallel arrangement and two respective detent features, one for each strut.
- the two detent features may be provided by respective downwardly extending prongs of a locking member fork.
- the convex surface may be provided with end stops at opposite ends thereof, which end stops limit travel of the detent along the convex strut profile so as to limit transverse pivoting of the handle portion to upper and lower arc boundaries.
- the other end region of the strut or struts may be attached to the base portion via a pitch pivotal connection.
- the aforementioned pitch pivotal connections permit the vertical travel of the base portion with respect to the wheel means.
- Said one or more rotatable work head typically support the base portion on the floor surface with the linkage permitting floating vertical travel of the work heads with respect to the wheel means.
- the articulated joint permits side-to-side pivoting of the handle about the joint about an axis perpendicular to the pivot transverse axis.
- the side-to-side pivot of the articulated joint is provided at a location vertically / rearwardly spaced apart from the transverse pivot.
- a side-to-side pivot locking mechanism is provided in which entry of a traveller associated with the handle portion into a constraint feature prevents side-to-side pivoting.
- the traveller is a retractable shuttle accommodated in a lower end region of the handle portion. The shuttle may be movable from a retracted position in which side to side pivoting of the handle portion is permitted, and an extended position in which a distal end of the shuttle is constrained (e.g. between cheek features) which prevent pivoting from side-to-side of the handle portion.
- the cheek features may define a generally vertical enclosure for accommodating the distal end of the shuttle, the shuttle traveling axially with respect to the handle portion, so that when the shuttle distal end is constrained the handle is dead centre of the side- to-side handle movement range.
- the traveller/shuttle may be capable of acting on said locking member fork to cause locking of transverse handle portion pivoting as the side-to-side pivoting is locked.
- the locking member fork and traveller may be connected by a pin and track engagement which provides vertical pin constraint and limited lateral pin freedom corresponding to side-to-side handle portion pivoting.
- the track is preferably arcuate in form.
- Movement of the traveller towards the constraint condition may cause the pin to act on the track constraint, and wherein the track is provided in the locking member fork, so that movement of the traveller causes movement of the fork into indent engagement.
- both handle portion pivot axes may be locked at the same time, conveniently with the handle portion in a generally vertical orientation.
- the traveller or shuttle may be resiliently biased so that when actuated the
- a distal end of the handle portion may be provided with a transversely oriented handle bar for the user to grip with a hand on each side of the bar.
- An upper end region of the handle portion may be provided with a handle position locking mechanism actuator.
- the wheel means may comprise a wheel, roller or ball, singular or co-axial adjacent pairs. Preferably there is a single wheel, roller or ball, most conveniently disposed at a lower region of the handle portion.
- the wheel means may preferably have a fixed transverse axis of rotation (when placed on the floor). In other words there is no caster wheeling.
- the wheel or roller may however be adapted to tilt into a turn (so it tilts about an axis coaxial with the direction of travel).
- the articulated joint may comprise a yoke which accommodates the wheel, roller or ball of the wheel means, which yoke preferably pivots about the wheel rotation axis.
- the side-to-side pivot may be disposed on an upper bridging portion of the yoke.
- the side-to-side pivot may comprise a U-section bracket rotated 90 degrees with respect to the yoke and which receives a lower end of the handle, with a pivot pin bridging the bracket cheeks.
- the base portion and associated work head(s) may be disposed at a front region of the machine.
- the wheel means may be disposed aft of the work head(s) and base portion with the linkage coupling extending between the wheel means and base portion (preferably generally centrally of machine or a centre region of the base portion).
- the machine is a wet scrubbing machine. It may be provided with a cleaning fluid reservoir and cleaning fluid delivery outlet.
- a squeegee liquid collector is preferably provided which is coupled to the machine by a trailing linkage.
- the linkage may permit up/down travel of the squeegee collector with respect to the wheels means.
- the trailing linkage is preferably pivotably coupled to the wheel means co-axially with the transverse axis of the wheel means.
- the machine may be provided with a squeegee suction drive and dirty liquid collection reservoir.
- the squeegee collector may be able to adopt a transport (or storage) configuration in which the squeegee is pivoted down and depending from the trailing linkage (with the wheels/rollers on the floor), or folded up vertically away from the floor.
- Forward propulsion of the machine is preferably provided by work head rotation.
- the direction of rotation controls forward or backward movement.
- the propulsion can be provided by using two work heads which counter-rotate.
- the user can roll the handle slightly to roll the work head lightly which will cause improved traction on one side of the work head, which will induce forward propulsion if that side is the returning rotational side.
- the drive means may comprise one or more electric motors carried by the base portion and coupled to the work head or heads. In a preferred arrangement there are two generally disc-shaped work heads disposed side-by-side and oriented to rotate about a respective vertical axis of rotation.

- a handlebar 13 is transversely mounted via a bore at the top end region of the handle portion 12.
- a control unit (not shown) is also provided at the top end region. During use the user walks behind the machine and guides it over the floor surface to be cleaned using the handlebar 13.
- the bottom end region of the handle portion 12 is pivotally attached between upstanding ear portions of a generally U-section mounting bracket 14.
- the pivot is oriented fore-aft to enable side-to-side rotation of the handle portion relative to the bracket 14 about a pivot Axis 1 , as shown in the arrows A, A’.
- Axis 1 is substantially perpendicular to the length of the handle portion 12 and permits the handle to be swung transversely from side to side about the bottom end of the handle portion.
- the bracket 14 has a lower region which is configured as a fork or yoke 17 formed by two spaced apart downwardly extending cheek plates.
- a guide wheel 18 is located between the cheek plates and mounted for rotation about an axle (not visible) which is co-axial with Axis 2.
- the wheel has a central hub and a circumferential solid rubber tyre.
- the axle permits the mounting bracket, fork and handle portion to be pivoted forward/backwards, up/down through an arc around the transverse Axis 2 provided by the axle.
- the wheel 18 is arranged to enable rotation about a single axis (Axis 2) and is otherwise fixed in position.
- the wheel 18 may be configured to lean either left or right into a turn as a user manoeuvres the machine 18 around the floor surface. This can improve the handling of the machine 10.
- the same leaning could apply to other wheel means which may be used, such as a roller or a ball.
- a pair of elongate, forwardly extending, spaced apart, parallel mounting struts 21 are pivotally attached at rear end regions thereof to opposite respective sides the wheel axle 19 projecting from either side of the wheel 18.
- Front end regions of each strut are attached to a pair of upstanding, spaced apart generally trapezoidal upright brackets 22 formed on a rectangular work base plate 23. The attachment is made via a pivot connection 24 having a transverse axis of pivoting rotation.
- the rear end regions of the struts are each formed with a generally semi-circular (convex) hump 43, an edge of which defines an upper convex surface 40.
- the surface has at front and rear limits there of steps 41 and 42.
- a central portion of the surface is formed with a square cut-out (or indent) 44.

- a mid-region of the shuttle is formed with a vertically oblong bore 53 which accommodated the Axis 1 pivot rod 49.
- the handle portion may pivot around the pivot pin 49 from side to side, by an extent limited by the arc of travel of the track pin in the track 48.
- a coil spring 55 is accommodated in the upper end of the cavity. As shown in figure 3a and 33b the spring is compressed and acts between the top end of the shuttle and a bulkhead of the cavity, with the shuttle held retracted by the cable 54.
- the shuttle is a sliding fit in the cavity and on release of the cable restraint can travel downwards, to an extent limited by the oblong bore, as shown in figures 4a and 4b.
- a pair of internal side cheeks 56, 57 (figure 4a) of the prongs 17 of bracket 14 define an aperture into which the shuttle can impinge when the handle portion and shuttle are vertically oriented, as shown in figure 4a. Entry into this aperture of the lower end of the shuttle fixes or locks the handle portion in a vertical orientation (with respect to pivot Axis 1 ).
- the downwardly-shifted shuttle also shifts the fork member down too, by virtue of the pin acting on a lower edge of the track 48.
- the handle portion is vertical with respect to pivot Axis 2 (axle 19)
- the fork prongs 46, 47 engage with indents 44 in the upper edge of the struts 21. This immobilises the handle in a vertical orientation.
