Definitions
- TITLE OF THE INVENTION A machine for treating floor surfaces.
- the present invention relates to a machine intended for treating floor surfaces, and in particular to one such machine which comprises a frame or a chassis to which there are attached at least three wheels which rest on the floor surface and can roll thereon, of which wheels 0 at least one is driven by drive means, so as to enable the machine to moved over the floor surface by means of the wheels, and of which wheels at least one is steer- able so as to enable the machine to be moved along a path adapted for the displacement of a number of rotat- 5 able floor-treating devices.
- moving the machine is meant in the following that the machine can be moved by the wheels over a floor surface without carrying out a working function.
- floor-treating machines Various different types are known to the art, these machines being adapted to the floor-treatment function concerned, i.e. floor-washing, 0 floor-polishing or floor-rubbing-down functions.
- the present invention can be considered to relate to a driveable machine.
- the machine operator sits on the machine and guides said machine over the surface of a floor, although, as will be understood, the machine may also be remotely controlled, either by an operator who walks on one side of the machine, or via a robot-con ⁇ trolled system.
- a technical problem resides in the provision of a machine intended for treating floor surfaces, primarily a machine for sweeping large floor surfaces which is so constructed as to enable the machine to be guided easily along a desired path by one single wheel, and which is also constructed to be able to displace a number of rotatable brush-units or brushes intended for treating the surface of a floor, preferably, although not exclu- sively, brush units having cylindrical surfaces.
- a technical problem is one of realizing that the ability to swing the machine around an outwardly jutting corner can be improved when the fixed wheel is positioned at a further distance from the centermost wheel than the pivotable wheel.
- a still more qualified technical problem to be solved is one of realizing that to enable the machine to sweep around an outwardly jutting corner, it is necessary for the fixed wheel to be located at twice, or substantially twice the distance in relation to the pivotable wheel, and that at least one rotatable brush unit should be located between the fixed wheel and the pivotable wheel, and in the vicinity of said pivotable wheel.
- a technical problem associated with a machine successful in solving a number of the aforesaid technical problems is one of providing a suitable location for the necessary batteries and driv ⁇ ing seat, not only with respect to machine stability and the ease with which the machine can be swung, but also with respect to the ease with which the operator sitting on the machine is able to anouver said machine.
- the object of the present invention is to provide a floor-surface treating machine which solves one or more of the aforesaid technical problems and which comprises a frame or chassis having mounted thereon at least three wheels which bear against the floor surface and are capable of rolling therealong, of which wheels at least one is driven by drive means so as to enable the machine to be displaced or moved along a floor surface by means of said wheels, and at least one wheel is steerable so as to enable the machine to be displaced or moved along a path adapted to enable a number of rotatable, floor- surface treatment means to be displaced along said path.
- the centermost wheel of the machine when seen in the direction of forward movement the centermost wheel of the machine will be a driving and steering wheel, and that one wheel mounted on one side of the machine will be fixed in relation to said chassis and directed for movement of the machine in a straight line, either forwards or backwards, and that a wheel mounted on the other side of the machine is freely pivotable about a vertical axis.
- centermost wheel it also lies within the scope of the invention, for embodiments at present proposed, for the centermost wheel to constitute the rearmost wheel of the machine, as seen in the direction of forward movement of the machine.
- the fixed wheel is preferably located at a further distance from the centermost wheel than the pivotable wheel. It is also proposed that the fixed wheel is located at twice or substantially twice the distance from the centermost wheel than the pivotable wheel, with space for accommodating a rotatable device being provid ⁇ ed between the fixed and the pivotable wheel.
- the rotat- able device shall be positioned adjacent the pivotable wheel. It is also proposed that a rotatable brush unit is mounted between the fixed and the pivotable wheel, and that the rotational axis of the brush unit is located horizontally and at right angles to a rectilinear direc- tion of movement.
- the driving and steering centermost wheel can be rotated through 360°.
- the necessary batteries are placed in a chassis space be ⁇ tween the centermost wheel and the pivotable wheel, whereas the driver's seat is positioned adjacent to and above the pivotable wheel.
- the chassis preferably has a frame attached thereto, for carrying said two rotatable brushes.
- Those advantages primarily afforded by the driveable, floor-sweeping machine in accordance with the present invention reside in the ability to displace and move the machine with the aid of three wheels, of which one is a driving and a steering wheel, one is fixedly mounted in a direction conforming to normal rectilinear movement of the machine, whereas the third wheel is freely pivotal.
- the invention also enables batteries, driver seat and other equipment on the chassis to be arranged in a manner such as to impart stability to the machine.
- Figure 1 is a perspective view illustrating the basic features of the machine, and shows for illustrative purposes, machine parts which would normally be hidden from view
- Figure 2 is a perspective view of a suitable frame construction capable of supporting three wheels and a rotatable, cylindrical brush- unit in accordance with the principles of the invention.
- FIG. 1 illustrates in perspective an embodiment of a floor-surface treating machine, particularly a floor- sweeping machine 1.
- the machine 1 comprises a forward frame or chassis 2 which carries three wheels 4, 5, 6 which bear against a floor surface 3 and which can roll on said floor sur- face.
- One of the wheels, 4, is driven by drive means not shown, so as to enable the machine 1 to be displaced along the floor surface 3, by means of said drive means and said wheel 4.
- the machine 1 can be driven by said drive means in two mutually opposite directions, although it is assumed in the following that the direction indicated by the arrow "F" is the direction of forward movement of said ma- chine.
- the machine 1 is also allotted a longitudinal direction or a longitudi- nally extending plane "A".
- the rotatable, sweeping devices have the form of cylindrical brush-units with a horizontal rotational axis, although the inventive principles can also be applied to rotatable brush-units which have vertical axes of rotation.
- One of the wheels namely the wheel 4, is a steerable wheel and is steered by known"means 4a, so as to enable the machine 1 to be displaced and moved along a prede ⁇ termined path, essentially any desired path, adapted for enabling a number of rotatable floor-treating devices or brush-units 7, 8, 9 to work along parts of adjacent walls and around corners.
- Each of the brush-units comprises a cylindrical brush- unit.
- the brush-units are rotatably mounted on respec ⁇ tive, mutually parallel axles 7a, 8a and 9a respective ⁇ ly.
- the rearmost wheel, or centermost wheel 4 is both driving and steer ⁇ ing, whereas the wheel mounted on the left side of the machine is fixed and rotates in the direction of said direction of forward movement or parallel with the left chassis-part 21 of the chassis 20.
- the wheel 6 mounted on the other side of the machine 1, on the right side of said machine as seen in the direc ⁇ tion of forward movement thereof, is pivotally mounted to the right chassis-part 22 of said chassis.
- the distance of the fixed wheel 5 from the centermost wheel 4 shall be greater than the distance of the pivot ⁇ able wheel 6 from said centermost wheel, and it is preferred that the distance of said fixed wheel 5 from said centermost wheel is twice or essentially twice the distance of the pivotable wheel 6 from said centermost wheel.
- a rotatable brush-unit 7 Mounted between the fixed wheel 5 and the pivotable wheel 6 is a rotatable brush-unit 7 of the aforemen ⁇ tioned kind.
- the rotational axle of the brush-unit extends horizon- tally and at right angles to the direction of forward movement of the machine, or to the plane "A".
- the driving and steering wheel 4 can be rotated through 360°, in a known manner, and .is driven by an electric motor, a d.c. motor, not shown.
- the batteries 10 required for powering the machine rest on the chassis or frame in the space between the center- most wheel 4 and the pivotable wheel 6, whereas the driver's seat 11 is positioned adjacent to and above the pivotal wheel 6.
- a frame 12 is attached to the chassis 2 and carries, inter alia, the two rotatable brush-units 8, 9 before- mentioned.
- the wheels 4, 5 and 6 are orientated in or parallel with the plane "A", as illustrated in Figure 1.
- the brush-units 7, 8 and 9 can be orientated so as to be able to brush and sweep up against a wall-part as the machine is displaced therealong.
- This point 13 is located immediately opposite the wheel 5 and perpendicularly to the plane "A".
- the wheel 4 When the corner is located in this position relative to the machine 1, the wheel 4 is swivelled at right angles to the plane "A", as illustrated in Figure 2, and steers the machine away from said wall-part, which means that the fixed wheel 5 will describe a circular movement around the corner to an extent determined by the angle of said corner.
- the wheel 6 is, at the same time, swi ⁇ velled to a position corresponding to the position of the driving and steering wheel 4.
