Definitions
- the invention relates to a mobile floor cleaning machine with a chassis and with at least one rotationally drivable brush roller which projects laterally beyond the contour of the chassis at least on one of its end faces.
- Mobile floor cleaning machines are known for example in the form of sweepers or scrubbers with which a floor surface can be cleaned.
- the floor cleaning machines are moved along the floor surface.
- a traction drive can be used, but it can also be provided that the floor cleaning machines are moved by the user along the floor surface.
- To clean the bottom surface at least one brush roller is used, which is set in rotation and contacted the bottom surface. Difficulties arise in brush rollers when an edge region of a floor surface is to be cleaned, which abuts an edge, for example, to a vertical wall. Especially in the area of a gutter, the floor cleaning is often difficult.
- Object of the present invention is to develop a mobile floor cleaning machine of the type mentioned in such a way that it achieves a good cleaning result even in edge regions of a floor surface to be cleaned, where it requires a smaller space.
- the at least one brush roller has a frusto-conical roller part with an obliquely oriented to the horizontal cone axis, which forms the axis of rotation of the frusto-conical roller part.
- the floor cleaning machine according to the invention is characterized by a frusto-conical roller part whose axis of rotation is inclined at an angle to the horizontal.
- the truncated-cone-shaped roller part contacts the bottom surface, so that it can be cleaned by the frustoconical roller part.
- the frusto-conical roll part projects laterally beyond the contour of the chassis at one end face.
- the configuration of the roller part in the form of a truncated cone with the axis inclined to the horizontal has the consequence that the laterally adjacent at least in one of the bottom surface portion is inclined obliquely to the vertical over the contour of the chassis protruding end face of the roller part.
- the laterally outwardly projecting end portion of the frusto-conical roller member in the portion in which it contacts the bottom surface a greater distance from the chassis than bearing elements, which are arranged on the laterally projecting end face and the storage of the frusto-conical roller part serve.
- the contact with the floor surface The end region of the frusto-conical roller part thus has a larger lateral projection to the chassis than the lateral bearing elements of the frusto-conical roller part, so that there is no danger that the lateral bearing elements when cleaning an end portion of the bottom surface, for example, touch an edge or a wall.
- the lateral projection of the bottom surface contacting edge region of the frusto-conical roll member may rather be chosen so large that the bearing elements as well as other machine parts, such as wheels, can take a distance to a wall or edge, whereas the most projecting end portion of the wall or edge reached.
- the laterally outwardly inclined end region of the frusto-conical roll part thus makes it possible in a simple manner to reliably clean even edge regions of a floor surface.
- the space required for the provision of the frusto-conical roll part space is relatively small, so that the floor cleaning machine according to the invention can be designed very compact.
- the frusto-conical roller part has a base body which carries a bristle trim. It is favorable if the base body and / or the bristle facing are frusto-conical.
- the frusto-conical roller part has two opposite end faces with different diameters. It is advantageous if the frustoconical roller part projects laterally beyond the contour of the chassis at its end face with the larger diameter. The diameter of the frusto-conical roller part thus increases in the direction of the laterally projecting beyond the contour of the chassis end face.
- the frusto-conical roller part forms in an advantageous embodiment of the invention, the entire brush roller. In such an embodiment, the entire brush roller is configured frusto-conical and inclined with its axis of rotation to the horizontal.
- the brush roller has a cylindrical roller part with a horizontally oriented cylinder axis, which forms the axis of rotation of the cylindrical roller part.
- the brush roller comprises not only a frusto-conical roller part but in addition also a cylindrical roller part, wherein with the help of the frusto-conical roller part edge regions of the bottom surface can be reliably cleaned.
- the cylindrical roller part can directly adjoin an end face of the cylindrical roller part.
- the frusto-conical roller part and the cylindrical roller part have overlapping bristles, because this ensures that a good cleaning result can be achieved even in the transition region between the cylindrical roller part and the conical roller part, without the risk that between the two parts of the roll a narrow strip of the bottom surface remains, which is not detected by the brush roller.
- the frusto-conical roller part and the cylindrical roller part may have different speeds.
- the two roller parts can be connected to each other via a gear.
- the two roller parts can be driven by a drive device to rotate with different speeds.
- the drive device can have two drive motors which are each coupled to a roller part.
- the drive device may have only one drive motor, which drives the two roller parts via gear elements to rotational movements at different speeds.
- the frusto-conical roller part and the cylindrical roller part each have a base body which carries a bristle trim, wherein the two main body rotatably connected to each other and by means of a drive means of the floor cleaning machine can be set in rotation.

- the first bearing body may be fixed, for example, on a longitudinal member of the chassis. Alternatively it can be provided that the longitudinal member itself forms a first bearing body on which the brush shaft is mounted.
- Brush shaft carries the main body of the cylindrical roller part.
- a second bearing body is used, wherein this is penetrated by the brush shaft in a preferred embodiment of the invention.
- the second bearing body may be fixed, for example, on the first bearing body. It is advantageous if the second bearing body defines the obliquely inclined to the horizontal axis of rotation of the frusto-conical roller part.
- the brush shaft not only passes through the second bearing body serving to mount the frusto-conical roller part, but also from the main body of the frustoconical roller part.
- the brush shaft is rotatably connected to the main body of the frusto-conical roller part. This makes it possible to transmit a rotary motion of the cylindrical roller part via the brush shaft to the cylindrical roller part.
- the brush shaft is rotatably connected via a driver, which dips into a recess with the main body of the frusto-conical roller part.
- the driver is rotatably held in an advantageous embodiment of the invention on the brush shaft and immersed in a recess of the main body of the frusto-conical roller part.
- the driver is preferably pin-shaped or star-shaped.

- the floor cleaning machine comprises in an advantageous development of the invention, two rotationally driven brush rollers, each comprising a frusto-conical roller part, which protrudes laterally on one end face on the contour of the chassis.
- the two frusto-conical roller parts each form a complete brush roller such that the two brush rollers are each configured in the form of a frusto-conical roller part.
- at least one of the two brush rollers has a cylindrical roller part in addition to a frusto-conical roller part.
- the two frustoconical roller parts each comprise two end faces with different diameters, wherein the end faces of the two roller parts with the larger diameter are facing away from each other and the two roller parts project laterally beyond the contour of the chassis on these end faces.
- the frusto-conical roller part exerts a contact force on the bottom surface.
- the frusto-conical roller part in an advantageous embodiment of the invention bristles with different stiffness.
- the bristles of the frustoconical roller part projecting laterally outwards have a greater rigidity than the bristles arranged further inward relative to the longitudinal central axis of the floor cleaning machine.
- the frusto-conical roller part has bristles of different lengths.
- the bristles projecting laterally outwards relative to the chassis have a greater length than the bristles located further inward.
