Definitions

  • the invention relates to a floor mopping device comprising a columnar
  • Shaft with a front end, one surrounding the shaft, relative to its axis displaceable and rotatable sleeve, the shaft with the sleeve connecting, switchable freewheel device, the relative rotatability of the two parts limited to a predetermined direction of rotation and in the at least one stop extending parallel to the axis of the one Part with a rebound counter stop of the other part in Engagement, with a number of flexible, absorbent strips at the end of the Connects shaft and the sleeve together.
  • the freewheel device also works on the shaft fixed, switchable means together, the sleeve reach under in the area of an annular surface facing the end.
  • Such a floor mopping device is known from WO 97 24 973 A.
  • the latch takes place radially by the engagement of a collet with a gear a locking toothing.
  • the disadvantage here is that, due to the design, only a few stop surfaces are engaged, so that just on this Areas of high wear occurs. Since also the one acting against a spring Collet must withstand the necessary stall forces, is one accordingly high spring strength required, which makes operation even more difficult becomes.
  • the pawl is arranged in the known embodiment in the sleeve. It is dimensioned very small for reasons of space and accordingly in mechanically very sensitive.
  • the invention has for its object a floor mopping device of the beginning mentioned type to develop in such a way that with a simplified Manufacture results in greater robustness and the possibility of It is better to dewater strips after wetting.
  • the stop provided on the sleeve and has a base extending across the axis.
  • the stop forms thus normally an axially parallel projection that on a Axis surrounding, imaginary circular surface is arranged.
  • the attack the sleeve is associated with at least one counter stop on the shaft a shape and size corresponding to its shape. It is also possible, the stop and the counter stop or the partial stops and the partial counter stops to train completely in accordance.
  • the counter attack forms part of a ring surrounding the shaft. This is axially displaceable on the shaft and with a spring on the sleeve can be pressed, for example by a spring, which through a shaft enclosing, resilient foam ring is formed.
  • the flexible, absorbent strips can be made from any relevant previously known material consist, for example, of fiber strands, a Textile and / or a foam material. They are generally in distributed substantially evenly in the circumferential direction and are by Displacement of the sleeve in the direction of the end of the shaft in a loop designed, wetted with water and to carry out cleaning processes used. Following the dirt pick-up the strips are rinsed out in water and by relative displacement the sleeve on the shaft in a more or less extended position transferred. When the relevant position is reached, the sleeve arrives in engagement with the switchable means fixed on the shaft, the it in the area of an annular surface facing the end reach under and prevent the sleeve from easily moving in the direction can finally move back.
  • any relevant previously known material consist, for example, of fiber strands, a Textile and / or a foam material. They are generally in distributed substantially evenly in the circumferential direction and are by Displacement of the sleeve in the direction of the end of
  • the means are a component a bell attached to the shaft and open towards the end form, which at the same time encloses the freewheel device radially on the outside. This prevents the risk of injury and a good appearance reached.
  • the means can be permanently effective by means of a spring, for example by a leaf or coil spring that interacts with the means. They are expediently easily switched off using an actuation button designed.
  • the annular surface can have a radially outward projection limit the sleeve towards the end of the shaft.
  • the projection is annular and at the end of the sleeve arranged. The amount of material needed to make the sleeve can be significantly reduced without disadvantages in terms of the robustness or grip of the sleeve are accepted would.
  • the stop can be in the direction of action, i.e. in the direction in which he during the intended use on the counter stop abuts, be limited by a stop surface, which is a component an imaginary plane built in the axis of the shaft.
  • the stop is advisable by a limits the helical or inclined surface surrounding the axis.
  • a decreasing Inclination angle inevitably reduces the size of the stop surface has the consequence.
  • the application of angles of inclination between 5 and 35 ° is preferred for this reason.
  • the Stop includes several partial stops that are even in the circumferential direction are distributed. These can be consecutive with one or with engage several counter-stops.
  • the floor mop includes a columnar shaft 1, at the lower end 6 one
  • the number of flexible, absorbent strips 5 is fixed so that it cannot rotate are distributed substantially evenly in the circumferential direction. You can consist of fiber strands, but also if necessary a similarly flexible and absorbent textile and / or foam material. Your end facing away from the end 6 of the shaft 1 is at one Sleeve 3 fixed non-rotatably.
  • a freewheel device 4 is displaceable and relatively rotatable with it, however axially non-displaceably engageable to stretch the Strip 5 to effect and in the course of a relative rotation of the sleeve 3 in the strips 5 a tensile stress for the purpose of drainage cause.
  • the freewheel device 4 is an actuation button 10 assigned, which allows the strips 5 following such performed dewatering process loop-like and for to make a floor wiping process usable.
  • the floor mopping device then comprises a columnar shaft 1 which in the embodiment shown from a plastic-coated, metallic pipe
  • a clamp is provided for fastening, which strips 5 encloses in the middle and sprung into a radial bore of the shaft 1 is.
  • the ends of the strips facing away from the end 6 of the shaft 1 5 are fixed non-rotatably in a plastic sleeve 3.
  • the bottom end the plastic sleeve 3 is designed gear-like for this purpose, wherein the strips 5 inserted into the spaces between the individual teeth and using a plastic sleeve 18 with the outer circumference of the Sleeve 3 are pressed.
  • the underside is delimited by an annular surface 8 and on the upper side by Projections 9 evenly distributed in the circumferential direction (FIG. 4).
  • the Projections 9 are on a base extending transversely to the axis 2 arranged and so far are formed by axially parallel projections.
  • the stops 9 are in the position indicated in FIG Engagement with counter stops 15, which are part of a shaft 1 enclosing ring 16 and a shape corresponding to them and have size.
  • the ring 16 is axially displaceable on the shaft 1 stored and pressed resiliently against the sleeve 3 by means of a spring 17.
  • the Spring 17 is formed by a foam ring, the O-ring-like is designed and concentrically surrounds the shaft 1.
  • the ring 16 is on the inside of an axially parallel Groove 18 pierced, which has a radial projection 19 of Grips shaft 1 in the circumferential direction.
  • the stops 9, the Counter stops 15, the ring 16 and the spring 17 are of one Plastic bell 13 enclosed, the immovable on the shaft 1st is fixed, in the present case using a riveted joint.
  • the pin is delimited at the lower end by an inclined surface, the sleeve at the top by a compatible conical surface.
  • the position of the bell 13 on the shaft 1 is selected so that when reaching the relevant position of the sleeve 3 a Extensive stretching of the strips 5 results.
