Definitions
- the invention relates to a hand-held, mobile cleaning machine, in particular a scrubbing machine, with a cleaning tool which comes into engagement with the floor and which is fitted between front and rear sets of rollers which are held on the machine frame, one set of the rollers being driven and the cleaning machine by means of a Guide bar can be guided by the user.
- a hand-held, mobile cleaning machine in particular a scrubbing machine
- a cleaning tool which comes into engagement with the floor and which is fitted between front and rear sets of rollers which are held on the machine frame, one set of the rollers being driven and the cleaning machine by means of a Guide bar can be guided by the user.
- a Guide bar can be guided by the user.
- the front set of rollers can be driven, while the rear rollers or the rear roller are each freely pivotable about a vertical axis, so that the cleaning machine is "pulled" in operation by the front, driven rollers while the user can control the machine by loading the rear rollers or the rear roller by applying lateral forces to the guide bar so that it pivots about its vertical axis and thus causes a steering effect.
- This known construction has the disadvantage that, on the one hand, relatively large forces have to be applied by the user for the steering process and, on the other hand, that there is a large turning circle, which makes it particularly difficult to attach the cleaning machine to walls and the like in the desired manner. bring them in and move them away.
- a cleaning machine of the type mentioned at the outset is designed in such a way that the rear set of rollers is driven and the front set of rollers for steering the cleaning machine can be adjusted in a controlled manner by the user in its orientation.
- the rear set of rollers can have two and the front set of rollers can have one roller.
- the steering is no longer carried out, as in the known hand-held, mobile cleaning machines, in that the user tries the non-driven rollers by applying lateral forces on the handlebar to pivot about their vertical axes, but by a user-made, controlled adjustment of the orientation, the front set of castors being used for steering, while the rear set of castors is driven, so that it also moves results in easily controllable and precise driving.
- the cleaning machine can also be driven up relatively steep ramps without great difficulty, because then the majority of the machine weight rests on the driven rollers, as a result of which they are pressed into firm engagement with the ground. so that the required driving forces can be easily transmitted.
- the front set of rollers for steering in a controlled manner can be mechanically coupled to a handlebar that can be actuated by the user, wherein the guide bar can form the handlebar.
- a chain or a cable can be used for mechanical coupling, for example.
- the scrubbing machine shown in FIGS. 1 and 2 has a machine frame 1, on which a housing 2, which covers the indicated, essentially conventional components, is arranged.
- a housing 2 which covers the indicated, essentially conventional components, is arranged.
- two rear rollers 5 and a front roller 6 are attached, the front roller 6 being pivotable about a vertical axis 17 in the center plane of the scrubbing machine and not being driven, while the rear rollers 5 are driven in a manner not shown Scrubbing machine, such as an electric motor powered by a battery.
- a guide bar 7 to be gripped by the user is provided, which is located above the housing 2 and is rotatable on one supported, downwardly extending in the housing 2 axis 8 is fixed.
- a handlebar lever 9 which extends parallel to the guide bar 7, is non-rotatably fastened to the lower end of the rotatably supported axle 8.
- a cable section 28, 29 is fastened, which runs over deflection rollers partially indicated in FIG. 2, of which only the deflection and guide rollers 24 and 26 for the cable section 28 are shown.
- the front ends of the cable sections 28 and 29 are connected to schematically indicated Bowden cables 128, 129, which are attached to an abutment 20 (FIG. 3).
- the tension elements of the Bowden cables 128, 129 are guided around rollers 22, 23 and a rope sheave 16 and, with their front ends in FIG.
- the rope pulley 16 sits non-rotatably on the outer race of the bearing 18, which consists of two partial rollers with the bearing existing castor 6 non-rotatably connected and rotatable together with this about the vertical axis 17 fixedly attached to the machine housing 1.
- the non-driven roller 6 rotates about the axis 19 held by the two fastening struts 10 attached to the bearing.
- the steering lever 9 is also located therein 3 shown in solid position, and the roller 6 is aligned with the central axis of the scrubbing machine, ie the machine drives straight ahead.
- the user pivots the guide bar 7 into the desired position, as a result of which, by rotating the axis 8, the steering lever 9 is also correspondingly rotated, for example into one of the positions indicated by dashed lines in FIG. 3.
- one of the cable pull sections 28, 29 exerts a corresponding tensile force on the Bowden cable 128 or 129 connected to it, so that the cable pulley 16 and thus the roller 6 is rotated about the axis 17 or comes into a position as shown in broken lines in FIG 3 is indicated.
- the pulling element of the other Bowden cable is drawn into its sheathing due to the shortening of the connected cable section resulting from the corresponding displacement of the other end of the steering lever 9, so it does not hinder the pivoting movement of the roller 6.
- a chain can be used to adjust the front roller instead of a cable. It should be mentioned that in FIG. 4, identical or corresponding parts from FIG. 3 are identified by the same reference numerals and additionally by '.
- FIGS. 3 and 4 show a purely mechanical coupling between the guide bar and the front roller
- an arrangement with an electrical coupling is shown schematically in FIGS. 5 and 6, the same components as in FIG. 3 or the components from FIG. 3 having corresponding parts same reference numerals and are additionally designated.
- the roller 6 "sits on an axis 19", which is attached by means of two fastening struts 10 "via a schematically indicated bearing 18" to the machine frame 1 ", this bearing being designed such that the vertical axis 17" cannot be rotated with the Roller 6 "is coupled.
- On the axis 17” sits a gear 16 "which meshes with a gear 28" which is non-rotatably mounted on the output shaft of an electric servomotor 30 "(FIG.
- the servomotor 30 is connected via an electrical cable 18" to one in FIG 5 schematically indicated electrical encoder 31 "connected, which may contain, for example, a potentiometer, the position of which is a measure of the rotational position of the axis 17" and thus of the guide rail 7 ".
- the electrical transmitter 31 gives a corresponding signal via the cable 18 "to the servomotor 30" which is caused by the rotation of its output shaft and thus the gearwheel 28 "via the gear 16" causes a corresponding rotation of the roller 6 ".
