Definitions

  • the invention relates to a window cleaner according to the preamble of claim 1.
  • Window cleaners of this construction are known in a large number of embodiments (EP-A-0 009 567, DE-B-2 529 061, DE-A-2 510 150), which, however, are largely similar in construction.
  • the carrier strip usually has a groove-like profile on its front edge, into which, for example, a rubber wiping strip with a lip profile is inserted as a cleaning part. This wiper strip can be replaced when worn.
  • the carrier strip often has a clamping profile in order to be able to clamp a sponge or the like, which is used primarily for moistening and pre-cleaning the panes, while the wiping strip is used for the final cleaning and the pushing off of the water from the pane surface.
  • the handle usually grips the support bar at an angle to (DE-B-2 529 061, DE-A-2 510 150), on the one hand to maintain the necessary distance from the surface to be cleaned, and on the other hand to be able to exert the necessary pressure on the cleaning part.
  • the handle of these window cleaners is usually made in several parts, a short part rigidly connected to the support bar, which is attached to the support bar at an angle, being designed as a handle in order to be able to operate the cleaning device even without a handle.
  • a receiving part is mounted on a pivot axis, into which the actual handle of the cleaning device can be inserted, screwed in or fastened in some other way.
  • Latches are also provided in the area of the pivot bearing, in order to be able to fix the handle in different angular positions relative to the handle part, so that the relative position of the handle and cleaning part can be ergonomically optimized.
  • connection between the handle part and the receiving part is to be regarded as disadvantageous because, in order to set a different angular position or to dismantle the receiving part from the handle (in order to use the device only with the handle part), a clamping screw which is firmly tightened for a perfect fixation of both parts must be partially or completely solved, which is only possible with the appropriate effort.
  • the connecting parts threadaded bolt and clamping nut
  • the connecting parts are often made of metal, which must either be corrosion-resistant or else begin to rust slightly in the other case.
  • the invention has for its object to eliminate the aforementioned disadvantages.
  • the hollow pin arranged on one part has a spring action, which can be used by the eccentric engaging in the hollow pin in order to hold the jaws formed by the hollow pin against the bearing shell surrounding it on one part (receiving part or grip part) to brace a certain position.
  • the clamping connection By turning the eccentric by means of the clamping lever, the clamping connection can be released and, if necessary, a different angular position can be set.
  • a tensioning lever can be operated much more easily and with less effort than a tensioning screw or a union nut;
  • the hollow pins are provided on the outside or the bearing shell on the inside with at least two depressions arranged in different rotational positions and the other part in each case with at least one appropriately designed projection.
  • the user first makes a presetting by axially separating the hollow pin and bearing pin or grip part and receiving part a little bit until the protrusion (s) come out of the recesses and the two parts can be rotated against each other then bring them back together axially so that the projection can penetrate into another recess.
  • This change is possible at a certain position of the tensioning lever, in which the eccentric does not exert any pressure on the jaws of the hollow pin.
  • the clamping lever can be pivoted back into its clamping position, the jaws of the hollow pin coming into their locked position. In practice, three different rotational positions are sufficient.
  • an axial projection similar to a key bit and to the bearing shell for axial locking on the eccentric a breakthrough arranged similar to a keyhole.
  • the projection on the eccentric can be passed through the correspondingly shaped opening on the bearing shell.
  • the bearing shell is gripped behind by the projection, which is designed like a key bit, and the eccentric is thus axially secured.
  • the invention further provides that the hollow pin and the bearing shell are each arranged on a narrow transition part on the handle or receiving part and that the two transition parts add up to the full width of the handle or receiving part. This ensures a seamless transition between the receiving part and the grip part.
  • the tensioning lever is arranged at right angles to the swivel axis of the grip part and the receiving part and in the tensioned position in alignment with the receiving part under contact with the same.
  • the clamping lever is thus flush with the handle in the clamping position and extends in its direction of extension, so that unintentional lateral impact forces can act on the handle, but not on the clamping lever and thus the eccentric cannot unintentionally loosen.
  • the window cleaner consists of a carrier strip 1 with a wiper part 2 inserted therein in the form of a rubber strip with a lip profile, a handle part 3 and a receiving part 4 pivotably mounted thereon for a conventional round or polygonal handle 5.
  • the grip part 3 engages on the carrier strip 1 at an angle and is on the other hand connected via an axis running perpendicular to the plane of the drawing according to FIG. 1 to the receiving part 4, which together with the inserted handle 5 can be pivoted about this axis relative to the handle part 3 and can be locked in one or more rotational positions by means of a tensioning lever 6.
  • the handle part 3 has at its end receiving the support bar 1 a fork with two fork legs 7, 8 which overlap a shoulder 9 on the support bar 1 in the form of a box-shaped hollow profile.
  • an axle stub 10, 11 is arranged, which together form an axis of rotation for the carrier bar 1.
  • holes 12, 13 are provided in the opposite walls of the attachment, one hole 12 being open to the side via an incision 14 with a narrower cross section (see also FIG. 2), see above that the stub axles 10, 11 can be snapped into the holes 12, 13 by sliding the fork legs 7, 8 onto the shoulder 9 of the support bar 1.
  • the handle part 3 and the receiving part 4 for the stem 5 each have, as FIG. 2 shows, a shell-like transition part 15 or 16, in the area of which the two parts are reduced to approximately half their thickness, so that they do not start in the assembled state merge.
  • the pivot axis mentioned at the outset which is shown in FIGS. 2 and 3 with a dash-dotted line 17, is arranged.
  • the receiving part 4 has in the region of its transition part 15 a hollow pin 18 (FIGS. 3 and 4) which, like the grip part 4, is split in direct connection to the transition part 15.
  • the gap is designated 19 in FIG.
  • the hollow pin 18 forms two radially resilient jaws 20 which engage in a bearing shell 21 on the other transition part 16 of the handle part 3.
  • An eccentric 22 engages in the hollow pin 18, which also protrudes into the bearing shell 21.
  • the eccentric 22 is seated on the tensioning lever 6, which runs perpendicular to this.
  • the eccentric 22 On the transition part 16 of the handle part 3 there is also an inwardly projecting bearing pin 23 which is overlapped by the eccentric 22 and forms the actual pivot bearing for the hollow pin 18 and the eccentric 22.
  • the eccentric 22 has an axially and radially extending projection 24 similar to a key bit, which engages in a corresponding recess 25 formed in the manner of a keyhole on the end wall of the bearing journal 23 and in any position deviating from the cover position for axially locking the Eccentric and thus also leads the hollow pin 18 or the receiving part 4 on the handle part 3.
  • the projection 24 can be brought into cover position with the opening 25 so that the handle part 3 and the receiving part 4 move away from one another in the direction of the pivot axis 17 and can also be brought into engagement again.
  • the tensioning lever 6 By turning the tensioning lever 6, the axial locking is then reinserted.
  • the bearing shell 21 on the transition part 16 of the handle part 3 has three depressions 26 on opposite sides, while the jaws 20 of the hollow pin 18 each have a projection 27 at diametrically opposite points.
  • the projections 27 on the jaws 20 engage in two opposite recesses 26 on the bearing shell 21 of the handle part 3.
  • the projections 27 are seated in different recesses 26, so that the position of the receiving part 4 and thus of the handle 5 relative to the handle part 3 and thus relative to the carrier strip 1 or the cleaner part 2 can be changed.
  • the clamping lever 6 is pivoted again into its clamping position shown in FIG. 1, so that a firm connection between the grip part 3 and the receiving part 4 is again present.
  • the carrier bar 1 with the cleaner part 2 can rotate freely relative to the handle part 3 about an axis lying in a parallel plane (stub axle 10, 11), while on the other hand the angular position of the handle 5 relative to the handle part 3 and thus relative to the cleaner part 2 after loosening of the tension lever 6 can change.
  • the support bar 1 on the stub axles 10, 11 can, for example, in the position shown in FIG. 2, in which the support bar 1 and the handle are arranged in mutually perpendicular planes, be lifted by a locking mechanism (not shown).
