Definitions

  • the invention relates to a cleaning device for surfaces, in particular window panes, consisting of a handle bar, one end of which is formed as an inner sleeve surrounded by a rotatable outer sleeve provided with an internal thread and provided with an axially extending slot for receiving the pin of a holder, on the center strips or rod-shaped cleaning elements are releasably secured.
  • 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 the strip-shaped ones equipped with wiper blades Cleaning elements, the liquid is stripped from the surface to be cleaned.
  • a cleaning device is equipped with both types of cleaning elements, the operator only needs to turn the cleaning device through 180 ° for the two successive tasks.
  • 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.
  • a generic cleaning device is known from British Patent GB 1 280 579.
  • a two-part holder is carried by a pin into which the inner sleeve formed at the end of the handle bar can be inserted.
  • Holding jaws are attached to the upper ends of the holder halves, between which the cleaning element can be clamped.
  • One of the halves of the holder is firmly connected to the holder pin, while the second half can be pivoted away from the first to receive the cleaning element.
  • On the outside of the fixed holder half is formed a circumferential thread section around the holder half, into which the internal thread of the outer sleeve engages when it is rotated after it has been pushed axially over the inner sleeve. During this screwing, the swiveling holder half is pressed against the fixed holder half and the cleaning element is clamped between the holder jaws.
  • Another cleaning device in which a pin of a holder for a cleaning element can be inserted into an inner sleeve formed at the end of the handle bar, is known from British Patent GB 1,553,004.
  • a nut-shaped projection is formed on the outside of the pin.
  • the outer sleeve surrounding the inner sleeve has a corresponding groove which can be made to coincide with the slot of the inner sleeve by rotating the outer sleeve in the manner of a lock. In this position, the holder pin can be inserted into the sleeve. After the pin has been inserted, the projection of the pin is locked by rotating the outer sleeve and thus preventing the holder from falling out of the handle.
  • this cleaning device compared to that described above is that the holder can be easily attached to the handle end.
  • the holder is not connected to the handlebar with the strength required for a perfect wiping result.
  • this cleaning device it is also not possible with this cleaning device to attach more than one cleaning device at the end of the handlebar.
  • 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.
  • 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 ° positions and braced by rotating the outer sleeve, because the outer and inner thread 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 abutting 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 previously 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. The outer sleeve 3 shown as an individual part in FIGS. 15 to 17 is guided in this annular groove 14 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.
  • the half-shells 3a, 3b are welded together at their butt joint after positioning on the inner sleeve 2.
  • 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.
