According to FIG. 1, there is a run-off device 10, corresponding to a first embodiment of a base body 12, of U-shaped perflrl, which extends longitudinally. This base body 12 has two side walls 1 * t, 16, which close an acute angle that is open upwards, and the branches form the U-profile. The side walls ^ t 16, are joined by a floor 18, preferably in the form of vat, which forms the vas. tago of union of the profile in U, by the base body 12; on the upper side of each of the two side walls-14, 16, a wringing roller 20, 22 is mounted, which rotates freely and does not move axially. The squeezing rollers 20, 22 lie at the same height next to one another and form a recess 24 between the rollers used to insert the windscreen wiper carrier provided with the wet cleaner. Two fixing devices 26, 28 are arranged according to Figs. 2 and 3, in front walls 30, 32, opposite some distance and belonging to the base body 12, which consist of a part where, the drainer device 10, by means of these fixed-clone devices 26, 28, is fixed to two sections of the opening edge which are opposite in distance and approximately parallel, opening edge belonging to a take-up container (not shown), for the cleaning liquid, for example a bucket and with the edge sections of the bucket are fixed but joined together removably. The side walls 14, 16 of the base body 12 are constructed so as to be elastically flexible so that they have an elastic resistance against an opening or separation force. The side walls 14, 16, and the body 18, are provided on their outer walls with stiffening ribs 34, arranged at a distance from each other parallel to each other, extending perpendicularly * to the longitudinal direction of the body 12. These stiffening ribs 34 are constructed to grow strongly towards the floor 18, in order to achieve a resistance or rigidity to the increasing elastic flexing of the side walls 14, 16, when they are separated. The two draining rollers 20, 22, co-ordinated to the base or main body 12, of the sprinkler device 10, are mounted in a rotatable manner and parallel to each other and movably disposed approximately parallel to each other, against each other. of the flexible elastic tension force of the side walls 14, 16, and of the floor 18. The base body 12, for this purpose, consists of a material that generates an elastic tension force, material that can preferably be a synthetic material, such as, polypropylene, pol leti high-pressure log, polyurethane but also, a stainless steel spring. The longitudinal edges 38, 40, approximately parallel to each other of the side walls 14, 16, of the base body 12, are provided with respective rectangular sections of which, it is seen in Figs. 1 and 2 the section 42, in the side wall 14; this section or identical cuts are at both ends limited each time by means of two vertical narrow sides 46, 48, the height of which is somewhat smaller than the diameter of a drainage roller or ex-leader 20, 22, the length of these two cuts, is increasingly greater in its measurements than the length of a roller 20,22, so that each roller 20, 22, can be placed in a non-axially displaceable manner in one of the two sections 42, 44. In the region of the two upper sections of the side walls 14, 16 of the base body 12, support bearings 50, 52 have been provided for each of the two rollers 20, 22, where these bearings protrude upwards on the upper longitudinal edges 38, 40, of the two upper sections of the side walls 14, 16. These bearings 50, 52, consist of the present embodiment, each time three support layers 54, 56, open distributed over the length of the section at equal distances, that they form approximately a cylindrical cut and are formed in one piece on the outer side of the two side walls 14, 16; the bearing shells 54, 56 are each provided on their internal sides opposite each other with a receiving opening 58, 60, for the corresponding drip rollers 20, 22. These receiving openings 58, 60, of each Bearing bush 54, 56, are smaller than the diameter of the rollers 20, 22, however, in order to insert the wringing rollers 20, 22, in the bushings 54, 56, the upper free ends 62, 64 are constructed. , of these bushes 54, 56, elastically flexible, so that the rollers 20, 22, under a spring action from one side can be placed in the flexible bushes 54, 56. It is understood that the bushes 54 56 have an empty cross-section corresponding to the drip rollers, so that these rollers 20, 22 can freely swing but remain mounted, not displaceable in the axial direction. The receiving aperture 58, 60, of each bearing bushing 54, 56, is thereby limited by at least one elastic device, which is formed by the same cassettes 54, 56. For this purpose, the bushes 54 are manufactured. , 56 of a flexible elastic material, preferably non-textile material. The cross-section of the bushings 54, 56 corresponds approximately to the diameter of the circle of the rolls 20, 22, where, the opening 58, 60, of each casing 54, 56, has a peripheral angle of the section transverse salt of circular form of each roller 20, 22, less than 180 to reach the said effect or action of muelleo. The distance of the recess 24, of the rollers -Hos 20, 22, to the surface of the floor 18, of the base body 12, is less than the height of each narrow side of the windscreen wiper carrier, for the wet cleaner, with which the windscreen wiper carrier, after the runoff or removal of the cleaning fluid from the cleaner used for it, can be removed without great effort from the drain device 10.
The rollers 20, 22 are constructed in tubular form and are provided with bleed openings 66, approximately radial towards the axes of the roller extending in a longitudinally displaced row 90, with respect to the liner lines of the rollers 20, 22, of course, that the sliding openings 66, other hole shapes can also be chosen, such as, for example, in the form of a spiral. An inner wall 68, of the rollers 20, 22, of tubular shape, widens conically from its longitudinal center 70, to its two ends 72, 74, so that the internal wall 68, (see Figure 5) , in the longitudinal center 70, of each roller 20, 22, present the maximum wall thickness. With this, the flow of the cleaning liquid squeezed out from the cleaner, and which penetrates inside the rollers 20, 22, is essentially improved through the flow or flow opening 66. The two front surfaces of the base body 12, in the form of a U-profile, they are basically covered by the front walls 30, 32, which only at their inner end are joined to the floor 18, of the base body 12, in a flexible elastic manner, and are arranged at a distance increasing toward the upper end of the front edges of the side walls 14, 16 of the base body 12; The front walls 30, 32, are constructed on top of the two rollers 20, 22, as side guards 76, 78, extending approximately vertical and parallel, which serve to center the wiper pointer when it is placed on it. draining device 10. These lateral guides 76, 78, present in the plan view a U-shaped cross section, where naturally the open sides of the lateral guides 76, 78, oppose at a certain distance, the cross section in U-shaped, free in the plan view of the lateral guides 76, 78 opposite each other, is arranged symmetrically on the score 24, of the two squeegee rollers 20, 22, and has a cross section that is maximum for all sides next to an upper entrance end 77, 79, for the windscreen wiper carrier, and decreases to its lower ends 81, 83, very close above the two squeezing rollers. to 20, 22, growing to fit the thickness and length of the wiper carrier with the wet cleaner. A U-shaped rod, bent upwards and outwards on the front side 75, 77, of the lateral guides 76, 78, is fixedly fixed on its outer side with two pairs of support ribs 71, 73, vertical and at a certain distance parallel, each time fixed to a horizontal carrier plate 67, 69, with its lower ends. The two carrier plates 67, 69 are suitably supported on the sides between each other internal or rear opposite of the front walls 30, 32, and are at the upper ends of the front walls 30, 32, directed to certain distance against each other and arranged between the side walls 14, 16, below the upper longitudinal edges 38, 40, of these side walls 14, 16. In this manner, if a carrier when placed in the drainer device due to centering inaccurate impact against one of the curved walls, but especially on one of the two U-rods, 75, 77, of the side guides 26, 28, the lateral guide found can cushion the shock in a flexible elastic manner with the corresponding front wall. , and in this way the carrier will be centered between the two lateral guides on the recess between the rollers 24. The front walls 30, 32, of the body 12, have, at the upper end of their external sides, the devices fastening means 26, 28, with which the draining device 10 can be placed and detachably fixed, as indicated, on the upper edge of the opposite edges of a capture or collection vessel for the liquid. The fixing devices 26, 28, are formed in one piece as elastic snap hooks 80, 82, in a U shape, inverted and in the front walls 30 32, of the basic body 12. For this, it has been formed on the Inner side of a branch at U, 34, 86, which advances downwards at a certain distance under a U-shaped rod, 88, 90, a lace back 92, 94, which, or under the outer edge of an outer edge approximately horizontal of a collecting vessel for the liquid, they grip when the hooks 80, 82 are pre-elongated on the edge of the container. This way a secure seat of the draining device 10 is secured in the container or on it. The intermediate spaces in the form of grooves 96, 98, between the side walls 14, 16, and the front walls, such 30, 32, of the base body 12, simultaneously serve as current or drain openings for the pressure-squeezed cleaning liquid. from the wet cleaner (Fig. 1). In addition, on the body 18, of the basic body 12, provided each time in the center between the stiffening ribs indicated with the figure 34, drain openings. The operation of the dripping device 10, for the aforementioned carrier with moistened wiper which can also be indicated as a flat wiper, is as follows: first, the trickling device 10 is connected to the snap hooks or springs 80, 82, of its base body 12, U-shaped, with the upper edge of a pick-up container, for example, a bucket in a sun-dried manner. Thereafter, the approximately rectangular wiper carrier is placed with its two narrow sides simultaneously between the two lateral guides 76, 78, above the pair of wringing rollers 20, 22. Here, the carrier is directed through the two lateral guides 76, 78, almost plumb, so that the carrier can be pressed between the two squeezing rollers 20, 22, which will be separated against the elastic tension exerted by the basic body 12; so that the carrier can be pressed further down into the basic body 12. As mentioned, upon introduction of the windscreen wiper carrier, the two rollers 20, 22 are pre-squeezed in an elastic flexion separating one from the other. . Since the rollers 20, 22 are fixedly attached but movable in rotation with each of the side walls 14, 16 of the U-shaped basic body 12, by means of the bearing casings 54, 56, the lateral walls 14, 16, which have ribs with the increase of the open upward angle that is formed between them, will bend outwards, due to the rigidity of the basic body 12, this elastic deformation produces an elastic tension in the side walls 14, 16, and in the floor 18, of the basic body 12. This tension, exerts a force that is transmitted to the rollers 20, 22, and with this, to the contact surfaces between the dripping rollers. , 22, and the wet cleaner, together with the contact surface, thus produces the pressure necessary to squeeze, by means of which the cleaning liquid absorbed in the cleaner in the windscreen wiper carrier. The lateral guides 76, 78, on both front sides of the draining device 10 for the carrier of the impia-windscreen, ensure that the cleaning liquid during the draining or squeezing process will always be captured by the opening of the intake container and from this one will drain. The central arrangement of the draining device 10, in the intake vessel opening, further prevents the spraying of the injected cleaning liquid onto the long side edges of the intake vessel, in addition, it is the walls of the intake vessel they same, effective as protection of the injected, because the draining device 10, in essence is disposed in a recessed manner or at a lower level. As mentioned above, the base body height between its floor 18, and the recess of the rollers 24. has somewhat smaller dimensions than the height of the vertically directed narrow sides of the Umpia-windshield carrier having a rectanqual shape. so that, if the Impia-windshield carrier is placed between the draining rollers 20, 22. to the top of the floor of the base frame 12. the upper edge of the carrier will protrude upwards a little above the recess of the rollers 24. Because of the pressure exerted by the side walls 14, 16 of the base body 12, the windscreen wiper will be squeezed once again as the carrier comes out of the wiper device 10; by means of the lateral pressure force exerted by the side walls 14, 16, elastically flexible of the base body 12 together with the coefficients of sliding friction of the bearing casings 54, 56, between the two rollers 20. 22, and its bearings 50,? 2, a frictional force is produced which is directed upwards. In the event that the frictional force on removal of the windscreen wiper carrier from the squeegee device exceeds the total weight of the intake vessel already filled with the cleaning liquid and the squeezing device 10, mounted therein, it can be pushed up from the 10th floor; To cope with this possibility, can the following measures be combined or individually? a) the "" rrealo of an ejector supported on springs by means of the floor 18, the base body 12, which will facilitate the removal of the wiper-pa-windshield carrier from the device 10, runoff; b) the disposition < "< e a stepped surface projecting laterally of the floor 18, from a catching container for the placement of a foot of the service personnel preventing the removal of the whole of the cleaning device to consis- tente from the capture vessel v ? -driving from a surface of * po o; c) decrease in the friction force between the squeegee rollers?, 22, and its bearings 50, 52, by means of the positioning of a suitable material to the end pursued with coefficients as low as possible of sliding friction for example, pollartalos with pol 1 tetrafluoroetl leno / polyester of high density, ( polyethylene) The degree of runoff can be increased by an increase in the pressure force of the rollers, apart from the limited possibility of constructing for this purpose the basic body 12, more rigid, can the draining rollers 20, 22, as described above, used with radial shifting openings made in its cylindrical walls, since, the hollow spaces of the drip rollers 20, 22, from the two ends of each drip roll tapers conically towards their center, the liquid of cleaning squeezed in the runoff of a windscreen wiper towards the interior of the rollers 20, 22, can be conducted from the center of each roller 20, 22, at both ends by the pa network or the internal stroke inclinations that expand conically towards the outer ends of each roller 20, 22. In this way, the liquid of impiex-expri-mido is driven out more quickly and the pressure beats by means of the decreased surface partially increases so that the degree of drainage is improved. A second exemplary embodiment of the device, in FIG. 7, is indicated in its entirety with the digit 110 in this draining device are the guide elements 112, 114, directly connected with the socket or reception for the rollers. These guide elements are extended outwards, until they are above the lateral guides 76, 78, this prevents that when the cleaning body is introduced into the draining device, the cleaning body may slip or fall to the side. By means of the direct connection of the guide with the take-up of the draining rollers, the small distance between the body of the cleaner and the guide will be maintained, when the cleaning body is inserted between the draining rollers, they are bent or flexed. guide halves with the rollers and in this way a grip or holding of the cleaning body between the guide halves is prevented. In this exemplary embodiment, there have also been provided, between the stiffening ribs 34, 36, as well as on the side walls 30, 32, and also on the guide elements 112, 114, recesses with a thickness of reduced material, placed that, the stiffness of shaping of the draining device is generated by the stiffening ribs, * these notches cause a decrease in the hardness of the material. In Fig. 10, a cut is represented by this second embodiment. Here they present the lateral guides, springs, ejectors 128, 130, these springs, and an ejection device indicated with the number 126, facilitate the process of exit of the windscreen-wiper body, from the drip dis-post, if the pressure lateral, as in the previous modality, becomes a high-clarity one. Without such an ejection device, it could be that the body remains stuck between the rollers, the ejection springs 128, 130 are tensioned when the body is introduced into the draining device and they maintain their contraction until expulsion occurs. The guide elements added to the base embodiment of the first embodiment, that is, the recesses and the ejector, can also be individually added to the base version without damaging the embodiment or ease of manufacture of the invention. In particular, the other elements of the prolonged guides with the recesses of the rollers and the recesses, functionally independent of each other, in the form of realization, preferably of the present, are combined the extended guide elements, the recesses for saving material and the ejection device with the ejection springs. With this embodiment having the advantage, that by the common realization of the guide elements and the outlets for the draining rollers, a greater reduction of the number of constructive parts can be reached, and with this, a decrease in the expense and complication of the assembly.
