Definitions
- the invention relates to a floor cleaning machine according to the preamble of claim 1.
- This known device also discloses a wheel located at the rear of the machine.
- the wheel can be pivoted about an axis relative to the chassis of the device so that - for stability reasons - the contact point of the wheel is always moved behind the axis.
- the angle of the axis relative to the floor can be adjusted by means of an actuation knob.
- EP-A 2 011 426 CRIVELLARO shows a floor cleaning machine with two rear wheels, a steerable front wheel and two auxiliary front wheels which are arranged on mutually opposite lateral sides with respect to the steerable front wheel.
- the two auxiliary front wheels are used to avoid tipping over the machine when the user climbs in or out of the driver's seat.
- the steerable front wheel however, has only a driving function and cannot be adjusted in its height.
- a disadvantage of this known floor cleaning machine is that the brushes cannot be raised above the floor so that the floor can be damaged due to the brushes which are wetted by cleaning solution.
- US 2,749,996 PARKER ET AL. discloses a floor cleansing machine (sweeper) including a main frame carried by two wheels. Furthermore, two driving wheels are attached to the main frame and driven by means of a power unit. This sweeper also discloses a wheel located at the rear of the machine and which can be lifted or lowered vertically by means of the lever. When the rear wheel is moved downwardly to contact the floor the rear frame section together with the driving wheels is raised upwardly, so that the driving wheels are no longer in contact with the floor. However, when the wheel at the rear of the machine is lowered the front of the machine is pushed down and consequently the brushes are compressed. This is disadvantageous because compression of the brushed leads to an undesirable distortion of the bristles of the brushes so that the function of the brushes is impaired.
- a further mobile floor cleaning machine is known from US 7,302,734 NOWAK ET AL.
- This known cleaning machine comprises a hydraulically driven rotating brush, an air mover and a combination of a filter and a receptacle mounted on a chassis with two rear wheels and a front wheel.
- the steerable front wheel is driven by a hydraulic motor.
- a disadvantage of this known cleaning machine is that the brush cannot be raised when the cleaning machine is stored or put aside so that tracks or damages on the floor during storage or transport can occur.
- the invention solves the posed problem with a floor cleaning machine comprising the features of claim 1.
- the advantages of the floor cleaning machine according to the invention can essentially be seen therein that:
- a small or medium size machine can more easily be transferred over larger distances, e.g. to or from its accommodation;
- the machine has not to be tipped by pressing the handlebar downwardly to raise the brush or brushes above the floor when the machine is transferred or put aside.
- the operator's effort for pushing or pulling the machine forward or backward during a transfer is significantly reduced by eliminating the need of tipping the machine by pressing the handlebar downwardly at the same time;
- the brush or brushes are more gently treated compared to a two wheel machine where the brushes are compressed when the machine is not used and ultimately damaged.
- the front wheel is arranged between the two lateral sides of the chassis, preferably essentially centrically between the two lateral sides. This configuration permits the advantage that the front wheel can be positioned in the free space between the two brushes so that a compact brush unit including the front wheel and its actuator can be achieved.
- the floor cleaning machine comprises at least two front wheels which are laterally arranged and preferably essentially equally spaced relative to a vertical middle plane of the floor cleaning machine.
- the floor cleaning machine additionally includes an actuator to move the at least one front wheel from the upper position to the lowered position and vice versa.
- the actuator comprises an electric motor, preferably a linear motor to move the at least one front wheel from the upper position to the lowered position and vice versa. Due to this configuration the advantage can be achieved that the brush or brushes can be raised and kept in the raised position without the need of applying - a lot of - manual force so that the adaption of the machine is easy to handle.
- the actuator can be configured as a mechanical actuator, preferably as a threaded spindle to move the at least one front wheel from the upper position to the lowered position and vice versa.
- the at least one front wheel is coupled to a front end of a lever which is pivotably coupled to the chassis and which is rotatable about a pivot axis.
- a lever which is pivotably coupled to the chassis and which is rotatable about a pivot axis.
- the linear motor or the mechanical actuator e.g. a threaded spindle can be arranged with its longitudinal axis extending essentially parallel to the floor so that the height required by the front wheel together with the actuation mechanism can be minimized.
- the linear motor or the threaded spindle can be arranged with its longitudinal axis extending essentially vertically to the floor.
- the pivot axis is arranged orthogonal to the middle plane of the chassis.
- the at least one front wheel is moveable from an upper position, in which the front portion of the chassis is in a lowered position so that the at least one brush is permitted to contact a floor to be cleaned, to a lowered position, in which the front portion of the chassis is in a raised position so that the at least one brush is spaced from a floor to be cleaned.
- the brush or brushes can be lowered or raised by simply rotating the chassis about the central axes of the rear wheels so that apart from the moveable front wheel no moveable parts are needed in the machine for lowering and raising the brushes.
- the cleaning machine comprises more than one, preferably two brushes which are arranged on opposite sides of the middle plane of the chassis and which are rotatable about an axis each, wherein the axes extend on opposite sides of the middle plane of the chassis and transverse to the lower side of the chassis.
- the cleaning width of the machine can be enlarged without the need of a larger length of the machine.
- the at least one front wheel vertically protrudes beyond the at least one brush in a direction vertically away from the lower side of the chassis.
- the at least one brush vertically protrudes beyond the at least one front wheel in a direction vertically away from the lower side of the chassis.
- the at least one brush is arranged between the at least one front wheel and the rear wheels.
- the at least one brush comprises a vertical rotational axis.
- the at least one brush can be arranged with its rotational axis extending in a horizontal direction.
- the at least one front wheel is arranged in front of the vertical rotational axis of the at least one brush.
- the at least one front wheel is configured as a castor wheel.
- the at least one brush - in the lowered position of the at least one front wheel - is vertically raised about minimum 5 mm.
- the cleaning machine further comprises a handlebar which is suitable to move the machine on a floor to be cleaned.

- the terms “lower side of the chassis”, “upper side of the chassis”, “above”, “below”, “vertical” and “horizontal” are referenced to the cleaning apparatus positioned on the floor to be cleaned.
- chassis is understood as being a framework which supports and/or holds in position the various parts of the cleaning apparatus and to which the handlebar is affixed and the rear wheels are rotatably attached.
- a brush or “at least one brush” may include a plurality of brushes.
- range format is merely for convenience and brevity and should not be construed as an inflexible limitation on the scope of the invention. Accordingly, the description of a range should be considered to have specifically disclosed all the possible subranges as well as individual numerical values within that range. For example, description of a range such as from 1 to 6 should be considered to have specifically disclosed subranges such as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6 etc., as well as individual numbers within that range, for example, 1 , 2, 3, 4, 5, and 6. This applies regardless of the breadth of the range.
