Definitions
- the invention relates to a floor mopping device comprising a column-shaped shaft with a front end, a sleeve enclosing the shaft and displaceable and rotatable relative to its axis, a freewheel device which connects the shaft to the sleeve and can be switched off and which enables the relative rotatability of the two parts limited to a predetermined direction of rotation and in which at least one stop extending parallel to the axis of one part engages with a resilient counter stop of the other part, a number of flexible, absorbent strips connecting the end of the shaft and the sleeve to one another.
- Such a floor mopping device is known from US-A-5,509,163, the stops preventing the relative rotations of the sleeve on the shaft being assigned to the shaft. They are formed by a plurality of ribs distributed uniformly in the circumferential direction, which extend parallel to the axis of the shaft. Forming them onto the shaft involves a great deal of tooling. It is possible to limit the number of ribs to two, which makes it easier to form them. However, you will normally only get the sleeve after a more or less large backward rotation with the one
- BESTATI GUNGSKOP IE The pawl engages the counter-stop, which prevents it from achieving adequate drainage of the strips after a previous wetting with water.
- the pawl is arranged in the known embodiment in the sleeve. For reasons of space, it is dimensioned very small and, accordingly, is very sensitive in mechanical terms.
- the invention is based on the object of further developing a floor mopping device of the type mentioned at the outset such that greater simplicity is obtained with simplified manufacture and the possibility of better dewatering of the strips after previous wetting.
- a floor mopping device of the type mentioned at the outset in which the freewheel device interacts with means which can be switched off and are attached to the shaft and which engage under the sleeve in the region of an annular surface facing the end, the stop being provided on the sleeve and has a base extending across the axis.
- the stop thus normally forms an axially parallel projection, which is arranged on an imaginary circular ring surface surrounding the axis.
- the protruding parallel to the opening direction using such a molding tool can be dimensioned almost any size using an appropriate manufacturing method and divided into an almost arbitrarily large number of successive partial stops in the circumferential direction and / or in the radial direction, which allows the during the intended use of the counterstop on it to reduce the reaction forces exerted to such an extent that the freewheel device can be used without wear, regardless of their sizes. This is of great advantage with regard to the durability of the floor mopping device.
- the flexible, absorbent strips can consist of any relevant material known in the art, for example fiber strands, a textile and / or a foam material. They are generally distributed essentially uniformly in the circumferential direction and are designed in the form of a loop by displacing the sleeve in the direction of the end of the shaft, wetted with water and used to carry out cleaning processes. After the dirt has been picked up, the strips are rinsed out in water and moved into a more or less stretched position by moving the sleeve on the shaft. When the relevant position is reached, the sleeve comes into engagement with the switchable means which are attached to the shaft and which engage under an annular surface facing the end and prevent the sleeve from moving back towards the end without further notice.
- any relevant material known in the art for example fiber strands, a textile and / or a foam material. They are generally distributed essentially uniformly in the circumferential direction and are designed in the form of a loop by displacing the sleeve in the direction
- the user is thereby able to generate a tensile stress in the strips by means of a relative rotation of the sleeve with respect to the shaft, and to dewater the strips in this way.
- the application of axially directed holding forces is not necessary. This is a great advantage for the practical handling of the floor mopping device.
- the means form part of a bell, which is attached to the shaft and is open towards the end and at the same time encloses the freewheel device radially on the outside. This prevents the risk of injury and creates a good appearance.
- the means can be permanently effective by means of a spring, for example by means of a leaf or helical spring which interacts with the means. They are expediently designed to be switched off easily by means of an actuation button.
- the annular surface may limit a radially outward projection of the sleeve towards the end of the shaft.
- the protrusion is annular and is located at the end of the sleeve. The amount of material required for the manufacture of the sleeve can thereby be significantly reduced without having to accept disadvantages with regard to the robustness or grip of the sleeve.
- the stop can be in the direction of action, i.e. in the direction in which it lies against the counterstop during its intended use, be limited by a stop surface which forms part of an imaginary plane built in the axis of the shaft.
- the forces exerted by the counter-stop on the stop during a relative rotation of the sleeve are introduced vertically in such a configuration, which prevents the two surfaces from jamming and ensures that the surfaces can be detached from one another particularly smoothly following a previous dewatering process.
- the stop is expediently limited by a helical or inclined surface enclosing the axis.
- a decreasing the angle of inclination that the helical or inclined surface forms with the axis the easier the sleeve can be rotated relative to the shaft.
- Inclination angle inevitably leads to a reduction in the size of the stop surface. For this reason, the use of inclination angles between 5 and 35 ° is preferred.
- the stop comprises several partial stops which are evenly distributed in the circumferential direction. These can successively engage one or more counter stops. It has proven to be expedient if the stop of the sleeve is assigned at least one counter stop on the shaft with a shape and size corresponding to its shape. It is also possible to design the stop and the counter-stop or the partial stops and the partial counter-stops in completely identical fashion.
- the counter stop can form part of a ring enclosing the shaft.
- This is expediently axially displaceably mounted on the shaft and can be pressed against the sleeve with a spring, for example by a spring which is formed by a spring-elastic foam ring surrounding the shaft.
- FIG. 1 shows a floor mopping device in a schematic illustration
- FIG. 2 shows some functionally important parts of the floor mopping device in a longitudinal section
- FIG. 3 shows a part of the freewheel device in a cross-sectional illustration
- Figure 4 shows a part of the freewheel device in a view from the side.
- the floor mopping device comprises a columnar shaft 1, at the lower end 6 of which a number of flexible, absorbent strips 5 are fixed non-rotatably.
- the strips are distributed substantially uniformly in the circumferential direction. They can consist of fiber strands, but also, if necessary a similarly flexible and absorbent textile and / or foam material.
- Its end facing away from the end 6 of the shaft 1 is fixed non-rotatably on a sleeve 3. This is displaceable on the shaft 1 in the direction of a freewheel device 4 and can be relatively rotated with it, but can be brought into engagement axially immovable in order to extend the
- An actuation button 10 is assigned to the freewheel device 4, which allows the strips 5 to be designed in the form of a loop following a drainage process carried out in this way and to be usable for a floor wiping process.
- the floor mopping device then comprises a columnar shaft 1 which, in the exemplary embodiment shown, consists of a plastic-coated, metallic tube.
- a larger number of flexible, absorbent strips 5 are non-rotatably fastened, which consist of fiber strands.
- a clamp is provided for fastening, which surrounds the strips 5 in the center and is spring-loaded into a radial bore in the shaft 1.
- the ends of the strips 5 facing away from the end 6 of the shaft 1 are fixed non-rotatably in a plastic sleeve 3.
- the lower end of the plastic sleeve 3 is designed in the manner of a gearwheel, the strips 5 being inserted into the spaces between the individual teeth and being pressed to the outer circumference of the sleeve 3 using a plastic sleeve 18.
- the Protrusions 9 are arranged on a base extending transversely to the axis 2 and are formed by protrusions parallel to the axis.
- the stops 9 are in engagement with counter-stops 15, which form part of a ring 16 surrounding the shaft 1 and have a shape and size corresponding to them.
- the ring 16 is axially displaceably mounted on the shaft 1 and is pressed resiliently against the sleeve 3 by means of a spring 17.
- the spring 17 is formed by a foam ring which is designed like an O-ring and concentrically surrounds the shaft 1.
- the ring 16 is perforated on the inside by an axially parallel groove 18 which engages over a radial projection 19 of the shaft 1 in the circumferential direction.
- the stops 9, the counter-stops 15, the ring 16 and the spring 17 are enclosed by a plastic bell 13 which is fixed immovably on the shaft 1, in the present case using a riveted connection.
- the switchable means 7 are at the same time immovably assigned to the shaft 1, which engage under an annular surface 8 of the sleeve 3 facing the end 6 of the shaft 1 and are formed by a radially outwardly movable pin.
- the pin is delimited at the lower end by an inclined surface, the sleeve at the upper end by a conical surface compatible with it.
- the position of the bell 13 on the shaft 1 is selected so that the strips 5 are largely stretched when the relevant position of the sleeve 3 is reached. This is followed by a relative rotation of the sleeve 3, based on the bell 13, in the direction of the arrows shown in FIG. 4. It also results in a periodic up and down movement of the ring 16, while the stops 9 over the tips of the counter-stops
