  • the fastening devices 26, 28 are as elastic snap hooks 80, 82 in an inverted U-shape on the two end walls 30, 32 of the base body 12 molded in one piece.
  • Slit-like spaces 96, 98 between the side walls 14, 16 and the end walls 30, 32 of the base body 12 also serve as drainage openings for the from the Wet wiping squeezed out cleaning liquid (Fig. 1).
  • the operation of the wringer 10 for the above called wipers with wet wiping, which also as Flat wipers are referred to as follows: First is the wringing device 10 with the snap hooks 80, 82 of her U-shaped base body 12 with the upper edge of a collecting vessel, e.g. a bucket, releasably connected. After that the approximately right-angled wiper holder with its two Narrow sides at the same time between the two side guides 76, 78 above the wringing roller pair 20, 22 used.
  • the wiping insert carrier is thereby two side guides 76, 78 largely aligned vertically, so that the wipers between the two Wring rollers 20, 22 can be pressed against it the elastic biasing force exerted by the base body 12 be spread, so that the wiping carrier continues can be pressed down into the base body 12.
  • the two wringing rollers 20, 22 by the Insertion of the wiping element carrier apart in a flexible manner pressed. Since the wringer rolls 20, 22 each with one of the two Side walls 14, 16 of the U-shaped base body 12 through the Bearing shells 54, 56 rigidly but rotatably connected are, the ribbed side walls 14, 16 under enlargement the one they have formed, open to the top Bent outwards at an angle. Because of the inherent rigidity of the base body 12 becomes a by this deformation elastic tension in the side walls 14, 16 and in the floor 18 of the base body 12 constructed. This tension exerts one Force exerted on the wringing rollers 20, 22 and thus on the Contact surface between the wringer rollers 20, 22 and the wet wiping is transmitted. In connection with the contact surface the required squeezing pressure is generated by that absorbed in the wiping on the wiping carrier Cleaning liquid is squeezed out.
  • the central arrangement of the wringer 10 on the opening of the receptacle also prevents the transfer of splashed Cleaning liquid over the long side edges of the receptacle.
  • the walls of the receptacle even effective as a splash guard because of the wringer 10 substantially sunk therein is.
  • the height of the base body 12 is between the bottom 18 and the nip 24 dimensioned somewhat smaller than the height of the vertically oriented narrow sides of the about rectangular wipers, such that when the Wiper trimming carrier between the wringer rollers 20, 22 to Stop on the bottom 18 of the base body 12 used is, the upper edge of the wiper trim carrier just above the Roll gap 24 protrudes upwards.
  • the following measures can be provided individually or in combination will: a) the arrangement of a spring-assisted Ejector over the bottom 18 of the base body 12, through the pulling out the wiper insert carrier from the wringing device 10 is facilitated; b) the arrangement of a tread surface protruding laterally from the bottom 18 of the collecting vessel, to by putting the operator's foot on a lifting of the whole, from collecting receptacle and wringing device 10 existing cleaning device from one Counteracting stand space; c) Reduction of the frictional force between the wringer rolls 20, 22 and their bearings 50, 52 through an appropriate pairing of materials with as much as possible low coefficient of sliding friction, e.g. POM with PTFE / PE-HD.
  • the degree of wringing can be increased by increasing the roller pressure be increased.
  • the wringer rolls 20, 22, as above described, with radial drain openings in their cylindrical walls can be used. Because the Cavities of the wringer rolls 20, 22 from both ends of each Wrinkle roller is tapered towards the center that when wringing out a wiping trim inside the Wring rollers 20, 22 pressed out cleaning liquid which are from the center of each wring roll 20, 22 to theirs inner wall or conically widening at both ends Run-off slope to these outer ends of each wring roll 20, 22 headed. As a result, the squeezed cleaning liquid dissipated faster and the contact pressure through the reduced area is partially increased, so that the degree of wringing is improved.
  • a second embodiment of the wringer is designated as a whole by 110 in FIG. 7.
  • the guide elements 112, 114 are direct connected to the holder for the wringer rollers.
  • This Guide elements are up to the side guides 76, 78 extended. This prevents when inserting the Wiper body in the wringer that the wiper body can fold aside.
  • the guide with the holder for the wringer rollers is the Distance between wiper body and guide kept small.
  • Ejector springs 128 and 130 These ejector springs and an ejector designated 126 facilitate the Pulling the wiper body out of the wringer, if the contact pressure as in the present Embodiment is very high. Without such an ejection device the wiper body could get stuck between the rollers become.
  • the ejector springs 128 and 130 are used in the Introducing the wiper body into the wringer biased and maintain their tension until ejected.
  • the basic version of the first embodiment added guide elements, the recesses and the Ejection device can also be used individually for the basic version can be added without the feasibility of the invention affect.
  • the other elements of the extended guide with reel seat and the recesses functionally independent of each other.
  • the invention are the extended guide elements the cutouts to save material and the ejection device combined with the ejector springs.
  • This version also has the advantage that the common Execution of the guide elements and the holder for the wringer rolls further reduce the number of components and thus a reduction in assembly effort can be achieved.
