Definitions

• the present invention relates to a device for wiping flat surfaces, in particular floors.
• Floors with non-textile surfaces, but also other flat surfaces such as larger furniture surfaces, building roofs, floors of pools, for example swimming pools and the like, are wiped conventionally.
• cleaning should be achieved with a dry or damp wipe.
• the invention also relates to wiping insofar as it takes place in connection with another treatment of the surface, for example with the distribution of a coating.
• the invention is preferably directed to wiping floors in the interior area.
• the invention is based on the technical problem of specifying an improved device for wiping flat surfaces.
• the invention is directed to a device for wiping flat surfaces with a motor drive and a wiping surface, which is characterized in that the drive lies within a path width covered by the wiping surface when the device is moved by the drive.
• the drive is thus arranged within a path width that is covered by the wiping.
• the invention here enables the wiping surface (wiping cover) to come into a relatively short distance from this edge or to wipe entirely without such a distance because the drive, for example a wheel running between the web width detected by the wiping and the bottom edge as a drive part, is arranged within the detected web width.
• the drive wheel or the drive wheels is arranged within the wiping surface in such a way that a wiping reference section is connected downstream of the drive wheel or the drive wheels in the direction of movement of the wiping surface. This avoids "lanes" of the wheel or wheels.
• the invention is particularly directed to the wiping of at least approximately horizontal surfaces, that is to say those on which the wiper device is held by gravity during its movement.
• the drive will lie above the surface to be wiped.
• the drive is preferably arranged above the wiping surface, but in principle it can also be arranged in front of or behind the wiping surface in the direction of movement, as long as it remains in the web width.
• the invention thus also offers the possibility of providing a relatively wide wiping surface in relation to the structural size of the device, which is also essentially determined by the drive.
• the wiper device according to the invention preferably has narrow and long external dimensions in the sense of a projection onto the surface to be wiped, that is, a significantly larger extension in one direction than in a second direction perpendicular thereto.
• the numerical ratio of the dimensions of the longest and the narrowest side is preferably at least 2: 1, more preferably at least 2.5: 1 and in the best case at least 3: 1.
• a preferred basic form of the device in the projection onto the surface to be wiped is a narrow one long rectangle. Narrow, long external dimensions on the one hand allow a relatively large web width and on the other hand the overall device is not too large.
• the device can be used very flexibly when driving through narrow passages or when wiping narrow corners.
• the named external dimensions of the device are caused by the wiping surface, that is to say the wiping surface forms the edges of the device in the plane of the surface to be wiped or at least essentially corresponds to these.
• the wiping surface that is to say an exchangeable wiping cover, protrudes on one or more sides over other parts of the device and thus on the one hand enables particularly good wiping along floor edges and on the other hand forms a protective abutting edge.
• other abutting edges can also be provided, which are not formed by the wiping surface itself.
• abutting edges equipped with sensory properties can also be provided in order to indicate an automatic control of the wiping device to an impact on an obstacle and thus to trigger corresponding control reactions.
• the wiper device preferably moves forward in such a way that one and the same long side points forward during a wiping run. It is then wiped with the maximum possible web width and, on the other hand, the dirt pushed together during cleaning is pushed in front of it. This preferably also applies during and after cornering, so that the wiper device leaves no wiping strips in corners or curves.
• the First move the wiping device in a right-angled corner of a floor with the long side mentioned as far as it will go to the opposite edge then drive back, turn 90 ° in the direction of the future direction of travel (so that the long side described now points forward in the future direction of travel) , in this rotated position, drive along the edge again to the corner and then continue in the new direction from the corner. A journey with the front long side in the corner would be converted into a drive with the same front long side out of the corner in the new direction of movement.
• the wiping surface moves in an oscillating manner with respect to the rest of the device, for example oscillates or circles in one or else in two horizontal or vertical directions with respect to a base of the device. This means that the mechanical impact on the ground can be increased without having to run over the same track several times.
• a further embodiment of the invention provides for the wiping device to be equipped with a wiping surface not only on one side but on two opposite sides. The device can then be turned by the intervention of a user or automatically in order to be able to continue with the second wiping surface.
• the wiping surface is continuous, that is, forms a coherent surface in the mathematical sense.
• it is preferably closed in the sense of the direction of movement behind the parts of the drive that come into contact with the ground, so that no traces are created by wheels, drive belts and the like.
• wheels or belts are therefore preferably provided within the wiping surface or in the sense of the direction of movement in front of it or a part of it.
• the invention is also directed to an improved drive for moving the device over a surface, which has a flywheel that is movable and motor-driven relative to a base of the device and is designed to drive the device by moving the flywheel relative to the base, by at In some of these movements, static friction holding the device on the surface is overcome by inertia of the centrifugal mass and not in another part of these movements, the movements of the centrifugal mass relative to the base as a whole being iterative.
• Mass inertial forces are used, which arise from relative movements between a flywheel and a base that forms the fixed component of the device. In certain phases, these inertial forces result in a static friction holding the device on the surface on which it is to move being overcome. In other phases, however, the inertia forces should not overcome static friction. In the following, we shall speak in simplified terms of movement phases and phases of detention. Depending on the reference system, inertial forces are transferred to the base by the movements of the flywheel, which partly move it and partly let it adhere to the surface. In other words, the movements of the flywheel lead to a reaction of the base because the overall system tries to correspond to the conservation of momentum. However, the conservation of momentum is disturbed by the friction between the device and the surface.
• the base remains on the surface in the sticking phases, while it moves on the surface in the movement phases.
• This is preferably a sliding or sliding movement, but with a corresponding static friction in wheel bearings or between wheel surfaces and the surface, it could also be a rolling movement during the movement phases. Since the movements of the centrifugal mass are ultimately iterative with respect to the base, i.e. repetitive and thus enable continued movement, an overall drive concept is created that does not require a direct positive or non-positive connection between the drive parts and the surface on which the device is to move.
• the wiper device only touches the surface to be wiped with the wiping surface because no wheels, drive belts or the like have to be used.
• flywheel is part of the device and should not be used up by the drive concept according to the invention. Although an energy coupling will be necessary to generate the movement, the flywheel mass should be preserved as such in contrast to recoil drives such as rocket drives or jet drives.
• the invention thus enables sliding or rolling locomotion without coupling between the drive and the transport surface. This can be of interest, for example, if a positive or non-positive connection with the transport surface is difficult to produce, for example on very smooth surfaces, or if contact between the drive and the surface is not desired in the cleaning device according to the invention.
• an energy store in particular a mechanical spring
• the acceleration phase provided for overcoming the static friction can be facilitated by the energy store with correspondingly large forces, and the motor drive itself can only be used for feedback.
• the drive could press the flywheel against the spring force and thereby tension the spring, whereupon the drive is switched off and the spring is allowed to accelerate the flywheel relatively violently.
• rotary movements between the flywheel and the base are also possible. Circular movements are preferred. Two cases are conceivable in the case of the rotary and in particular the circular movements, which in principle could also occur in a mixed manner.
• the actual conservation of momentum in the sense of the linear momentum i.e. in the sense of the centrifugal forces, can be exploited.
• the conservation of angular momentum can also be used, in which the base experiences an angular momentum when the angular momentum of the flywheel mass is changed. If the case of linear momentum conservation is in the foreground, the flywheel will be arranged eccentrically with respect to the rotational movement.
• the flywheel is meant in the sense of the center of gravity and not necessarily in its physical form.
• a increased acceleration of the flywheel in certain areas of the track for example in the case of non-circular tracks such as sun or planetary tracks
• the angular momentum acting on the base in both cases, a "jerk" of the base can be created, which overcomes the static friction for a certain movement phase.
• the movement phases that is to say the “jerk movements of the base” generated by the inertial masses
• the static friction is also overcome in the context of "regressions”, which, however, lead to a less backward movement than the desired forward movement.
• the flywheel drive could briefly overcome the static friction limit even with inertial forces that are basically acting in the wrong direction. If the static friction limit in the desired direction is overcome for a longer time or at a higher speed, this does not in principle stand in the way of locomotion according to the invention.
• the device can become heavier or lighter at times and possibly also in places, in other words, it can be pressed onto the surface or relieved of gravity by appropriate inertial forces.
• particularly large inertial forces in certain movement phases it is possible to distinguish between movement phases and holding phases. For example, you can Inertial forces that remain constant in terms of amount in the movement phases result in components sliding against the gravitational force, and in adhesion phases in components that act parallel to the gravitational force to stick.
• the flywheels are preferably gimbally suspended from the base. This can serve to tilt the planes of rotation in the sense just described. Furthermore, in contrast to a fixed, unchangeable tilting, a corresponding adjustment of the cardanic suspensions can also be used to adjust the size of the static friction between the device and the surface and also to compensate for any directional dependencies of this static friction, for example in the case of aligned wiping textiles.
• the gimbal suspension is preferably set by means of a motor and can in particular also be done automatically in that the device tests the start of the movement phase to a certain extent and automatically adjusts itself to an optimal propulsion by adapting the tilting for given rotational movements.
• an opposite end of the device can serve as an axis of rotation and an oppositely directed and acting on the base angular momentum, ie a component perpendicular to the surface, can be used for a corresponding second step.
• the device would, for example, move alternately step-by-step with a right and a left side and thereby rotate about the other side.
• the angular momentum components can be generated either by tilting rotating gyroscopes or - less preferably - by accelerating or braking such gyroscopes.
• the device according to the invention does not necessarily have to be free from other drive or steering influences.
• it may also be desirable to provide an operator with an influence on the movement for example by applying a style for steering or also for supporting the movement.
• a motorized mop with style would make it easier for a cleaning person to slide the mop over the surface to be cleaned on the one hand, on the other hand the mop could also be much heavier and therefore more effective in terms of cleaning effect than a conventional manually operated mop.

• a wheel drive is provided within a wiper device 30 and is arranged within the wiper surface (corresponding to the wiper device 30 in the plan view from FIG. 9), in which two wheels 31 and 32 can be driven independently of one another and rotated relative to the wiper device 30.
• the wheels are shown in two different positions, but there are two wheels in total.
• the wiping device 30 can be transported with its wiping surface over the floor, any direction of movement and also rotations of the wiping device 30 being caused by speed differences between the wheels 31 and 32 and by motorized adjustment of the angle of the axes of rotation of the wheels 31 and 32 relative to the wiping device 30 around their own axis. It must be ensured that the frictional connection between the wheels 31 and 32 and the floor is sufficiently high in relation to the sliding friction on the wiping surface thereon.
• FIG. 9 illustrates in particular that an arrangement within the wiping surface is also possible with this drive, and any traces on the floor which may be caused by the wheels 31 and 32 can be wiped away regardless of the direction of movement.
• the wiping area is namely a closed area around the drive.
• FIG. 10 shows a front view of a wiping device 33 which has a wiping textile 34 which projects beyond the lateral edge of the actual wiping device 33.
• This wiping textile 34 serves as edge protection and furthermore limits the dimensions of the wiping device 33 in the projection onto the floor. This allows particularly efficient wiping along wall edges without the risk of damage due to the wiping device 33 bumping.
• the wiping devices according to the invention can of course also have corresponding impact protection edges, independently of wiping textiles, which can also take on sensor functions in order to inform the aforementioned electronic control 11 of a collision with an obstacle.
• FIG. 11 shows, as a basic diagram, a cross-sectional view shown in the viewing direction of FIG. 10 through a base station 35 according to the invention for regenerating the wiping device 33.
• the wiping device 33 with the wiping textile 34 is guided between squeezing rollers 36, 37, 38.
• the distance between squeezing rollers 36 and 37 or between squeezing rollers 38 and 37 is adjustable so that the force with which the wiping textile 34 is squeezed out can be determined in a suitable manner.
• the squeeze rollers 38 press on the wiper device 33 itself and the squeeze rollers
• FIG. 12 shows a somewhat more specific training example for the base station, which is designated 39 here.
• the wiping device 33 from FIG. 10 or, for example, also the wiping device 10 from FIG. 5 or the wiping device 9 from FIG. 3 can be moved into the one on the left in FIG. 12 with the aid of its own drive position shown are driven. There they are gripped by two levers 40, which can be tilted by a motor in the manner shown.
• resiliently mounted pins which are explained in more detail below, are engaged behind undercuts in the grooves 41 which can be seen in FIG. 12 on the respective front regions of the longitudinal sides of the wiper device 33.
• the levers 40 can grip the wiper device 33 and lift it in a tilting manner, as a result of which the front end of the wiper device 33 is guided between squeezing rollers 42 and 43.
• the squeezing rollers 42 and 43 pull the wiper device 33 further upward at an angle, the insertion pins disengaging from the catches and instead continuing to run in the grooves 41 as a guide.
• the wiper device 33 is transported in this way to an inclined plane 44, the squeezing rollers 42 and 43 expressing residual moisture in the wiper textile 34.
• the cleaning liquid running off flows through a continuous filter 45 into a dirty water tank 46, from which the cleaning liquid correspondingly cleaned by the filter 45 is fed with the aid of a pump 47 to a nozzle 48, which cleans the cleaning liquid to improve cleaning before
• Fresh water tank 50 is provided, for example for a
• Final wipe cleaning contains clear fresh water for rinsing and can accordingly be connected to the nozzle 48 in a manner not shown. Furthermore, the cleaning system can perform a multiple, initially wet and then drier wiping in the manner already described.
• the oblique movement of the wiper device 33 on the level 44 enables the wiper device 33 to be easily transported into the base station 39 with the aid of the motor-driven lever 40 so that the wiping textile 34 of the wiping device 33 is accessible and space is created for the components described below the level 44.
• the hydraulic unit on the flow filter 45, dirty water tank 46 and nozzle 48 and fresh water tank 50 can also be completely removed as a module.
• the distances between the rollers 42 and 49 with respect to the rollers 43 can also be adjusted in order to ensure optimum pressing and a sufficient frictional connection for the transport.
• the residual moisture in the cleaning textile 34 can also be adjusted.
• the setting can be made, for example, by eccentrics in the axis of rotation bearings.
• FIG. 13 illustrates the latching mechanism already mentioned for gripping the wiper device 33 by the levers 40.
• On the lower left one of the two levers 40 can be seen, which carries at its end a pin 52 which is spring-mounted by a spring 51.
• FIG. 13 is reversed in relation to FIG. 12.
• the groove 41 already mentioned has an undercut 53 in its initial region, that is to say in the vicinity of its right end in FIG. 12 and the left end in FIG. 13, into which the pin 52 can snap. The engagement is facilitated by a bevel 54 at the beginning of the groove 41.
• the disengagement from the undercut can take place either by means of a similar incline with the aid of the forces exerted by the squeezing rollers 42 and 43 or with the aid of a further mechanical disengagement, which is indicated here by the motor-driven fork 55. This can grip the pin 52 and pull it outward from the undercut 53. The pin 52 then slides along the groove 41 as a guide.
• a base station can also be designed to provide a wiper device with two wiping textiles (cf. 5) to rotate by 180 °.
• FIG. 14 shows schematically that the base station 39 can also serve to replace the wiping textile 34 in a second department, if necessary.
• FIG. 14 shows how the wiping textile 34 is pulled off two rollers 56 and 57 by Velcro fasteners (not shown in more detail) on the lower surface of the wiping device 33 and placed in a container 58.
• the various motorized movement steps in the base station 39 can be controlled by light barriers or similar sensors. As soon as the wiper device 33 is gripped, the typical current profiles of the electric motors involved can also be used in order to draw conclusions about the respective movement phases.
• optical evaluations of the degree of soiling of the floor, the wiping textile, the cleaning liquid in the wiping textile or also in the container 46, the degree of soiling of the filter 45 and the like can be used.
• the base station 39 can be programmable to certain
• Wiping textiles can also contain transponders that are read in the base station.
• the electronic control 11 of the wiper device which can possibly also be reprogrammed by an electronic control of the base station, can be operated by the wiper device (in whatever specific design) Control consideration of known data of room dimensions and floor characteristics or those determined during previous trips. The user can also specify the rooms to be cleaned and thus call up known data records or enter essential characteristics of such rooms.
• the wiper device can carry out an automatic position determination, for example by known odometric methods, by determining the movement distances and directions and thus determining the current positions. A position can of course also be determined in a different way, for example using laser measuring systems.
• the wiping runs are preferably S-shaped with preferably the same leading longitudinal edge. This means that large areas can be cleaned with just a few trips and little overlap of the web widths recorded. The movement already described, with the front edge always remaining the same, also prevents dirt strips from being deposited in curves or corners.
