Definitions

  • the invention relates to a cleaning device for surfaces, in particular window panes, consisting of a handle bar and a holder for one or two detachably attached, strip or rod-shaped cleaning elements.
  • cleaning devices of this type strip-shaped cleaning elements equipped with wiper blades or rod-shaped cleaning elements equipped with sponge or lambskin-like coatings are used.
  • the cleaning elements equipped with such coatings the surface to be cleaned is wetted with cleaning liquid, while with the strip-shaped cleaning elements equipped with wiper blades, the liquid is wiped off the surface to be cleaned.
  • a cleaning device is equipped with these two types of cleaning elements, the operator needs them successive work, just turn the cleaning device 180 o .
  • Such cleaning elements are detachably attached to the more or less long handle bar, but the fastening means are not designed for quick and frequent changing of the cleaning elements.
  • the invention has for its object to provide a cleaning device of the type mentioned, in which the cleaning elements can be exchanged with a quick handle and permanently fixed against axial movement in the direction of the axis of the holder and against rotation about the axis of the holder.
  • the cleaning device should be suitable for a wide variety of equipment with cleaning elements.
  • a cleaning device of the type mentioned which is characterized in that the handle bar carries at one end an inner sleeve with two axial, opposite slots, on which an outer sleeve with an internal thread is rotatably but axially immovable, which has two opposite recesses in the form of axial grooves, which can be brought into a position aligned with the slots by rotating the outer sleeve, and that an axially longitudinally divided pin can be inserted into the inner sleeve, at least one pin half of which is a cleaning element and this pin half and the other pin half each carry an internal thread section corresponding to the internal thread, the width of which corresponds to the width of the slot and the groove in such a way that when the slot and groove are aligned, the pin can be displaced in the inner sleeve and by rotating the external screw is locked axially on the sleeve, the pin mating threads.
  • the cleaning device according to the invention can be equipped with a single cleaning element or two different cleaning elements.
  • the second pin half carries no cleaning element. In this case, it only contributes to the fixation of the other pin half carrying a cleaning element.
  • the cleaning elements can be released or axially locked in the inner sleeve. A laborious unscrewing, possibly even with the help of tools, is not necessary. Securing against rotation about the axis of the holder takes place via the positive locking of the external thread sections of the two pin halves, which engage in the axial slots of the inner sleeve.
  • both internal and external thread sections are designed identically.
  • the longitudinally divided pin can be inserted into the inner sleeve in both 180 o positions and clamped by rotating the outer sleeve, because the outer and inner threaded sections correspond to one another in each of the two positions.
  • the inner sleeve has such a stop for the pin that when the pin abuts the stop, the external thread sections correspond to the internal thread sections. A cumbersome axial alignment with regard to the corresponding external and internal thread sections is therefore not necessary.
  • the two cleaning elements can be moved relative to one another in the axial direction of the pin.
  • the two pin halves are axially secured on their adjacent inner sides by a toothing, the division of which is matched to the division of the threaded sections in such a way that in every possible axial Position of the two pin halves correspond to the threaded sections.
  • the two pin halves can be secured on their inner sides that lie against one another by an axial tongue and groove connection against rotation about a normal axis on the inner sides.
  • This tongue and groove connection does not adversely affect the above-described axial displacement of the two pin halves in the pitch of the toothing.
  • the two inner sides of the pin halves are designed identically with regard to the toothing and / or the tongue and groove connection.
  • the cleaning device has a hollow cylindrical handle bar 1, into which an extension bar can be inserted, a hollow cylindrical inner sleeve 2 formed thereon, an outer sleeve 3 rotatably but axially immovably mounted thereon and a two-part holder 4 which is connected to an axially split pin 5, 6 is in the inner sleeve 2.
  • One holding part 7 of the two-part holder 4 is set up for screwing on two rod-shaped arms which can be equipped with a tube-like covering made of a lambskin-like or other absorbent material. To increase the absorption of liquid are in the Holding part 7 and the arms 8 chambers 9,10 formed.
  • the other holding part 10 of the holder 4 is set up for screwing on a strip-like wiper blade.
  • the inner sleeve 2 has two diametrically opposite slots 11, 12 which are open towards the end face. On its side opposite the open end face, the inner sleeve 2 is pot-shaped, the bottom 13 of the end face of the two-part pin 5, 6 serving as a stop.
  • An annular groove 14 is embedded in the outside of the wall of the pot-shaped part. In this annular groove 14, the outer sleeve 3 shown as an individual part in FIGS. 15 to 17 is guided with a correspondingly designed collar 15, as shown in FIGS. 2 and 6.
  • the outer sleeve 3 is composed of two half-shells 3a, 3b for assembly purposes. After positioning on the inner sleeve 2, the half-shells 3a, 3b are welded together at their butt joint.
  • the outer sleeve 3 has two absolutely identical internal thread sections 16, 17, between which diametrically opposite axial grooves 18, 19 extend to the end face of the outer sleeve 3.
  • the width of these axial grooves 18, 19 is equal to the width of the axial slots 11, 12 of the inner sleeve 2.
  • the two pin halves 5, 6 of both holding parts 7, 10 are of absolutely identical design. On their outer circumference they carry a section 20, 21 of an external thread, which corresponds to the two sections 16, 17 of the internal thread of the outer sleeve 3 corresponds.
  • the width of the threaded sections 20, 21 in the circumferential direction is equal to the width of the axial slots 11, 12 and grooves 18, 19.
  • the inner sides of the two pin halves 5,6 lying one on top of the other carry two axial rows of teeth 23, 24, 25, 26 and between them a tongue 27, 28 and a groove 29, 30 .
  • the arrangement of these elements is absolutely the same for both pin halves 5,6, the pitch of the toothing of the rows of teeth 23, 24, 25, 26 being matched to the threaded sections 20, 21 in such a way that in each axially offset position of the two pin halves 5,6 in the case of an abutting face 13 on the bottom Pin half 5 or 6, the threaded sections 20, 21 of the pin halves 5, 6 are aligned with the internal thread sections 16, 17 of the outer sleeve 3.
  • the interlocking tongue and groove connections 27, 30 and 28, 29 enable the axial movement of the two pin halves 5, 6 towards one another, but prevent angular displacement about an axis perpendicular to the pin axis.
