    Descriptive Report of the Invention Patent for CLEANING BLADE IN THE FORM OF BEAM CONSTRUCTION WITH A SUPPORT ELEMENT.
    State of the art [001] The invention relates to a cleaning blade produced in the form of a flattened rod.
    [002] From the document DE 100 58 208 A1, a cleaning blade of this kind has become known, in which, in the central region, a coupling element of a suitable material, for example, synthetic material, is attached to two elastic rails that serve as a support element. The coupling element has, on the longitudinal sides, driving profiles with which it embraces the elastic rails from the external longitudinal sides at the top and bottom, as well as on the side faces. Between the two elastic rails, a fixing element is provided that rests on the connecting element and which fixes the elastic rails with closure due to their shape and / or force. As a fixing element, a pin is provided that moves approximately in a vertical direction towards the wide side of the elastic rails, in a perforation of the coupling element, pressing the elastic rails outwards, with closure due to the force, against the conductive profiles of the coupling element. In some conformations, the pin can also penetrate indentations on the internal sides of the elastic tracks, so that in an additional character or instead of the closure due to the force, a closure due to the shape is achieved. The closure due to the shape can, in addition, also be reinforced by the fact that on the external sides of the elastic tracks there are also cutouts in which protruding parts penetrate in the region of the conductive profile. When assembling, the fixing pin is secured in its conduction, for example, by an adjustment pressed by means of glue, weak solder, hard solder, repressing, pressing, screwing or otherwise being fixed in its position

    Description of the Invention [003] According to the invention, the fastening element has a u-shaped cross-section with two walls interconnected with a bottom that are shaped in niches on the inner sides of the side walls of the coupling element, the bottom of which fastener extends in parallel to the bottom of the coupling element and as extensions of the side walls of the fastener element are joined in the direction of the elastic rail with the splints on the side walls, which penetrate through openings in the bottom of the coupling element, in the cutouts of the elastic rail.
    [004] The cleaning blade with the coupling element and its fixing element constitutes a simple fitting system, in which the assembly can be carried out by simple handling in a short time. In addition, by simplified assembly, the risk of incorrect assemblies is reduced. The fixing element itself is a stable built element that transfers the forces acting on it in wide extensions and free from gaps to the coupling element. The surface compressions relevant to wear are very low. Therefore, you can perform other functions, for example, you can accommodate mounting elements for the articulated connection with the cleaning arm. For this purpose, the fixing element advantageously has perforations on the side walls that serve as a hub or to receive an articulated shaft. If the articulated shaft is upturned on the side walls of the fastener, the fastener will present in the region of the heads of the rivets that protrude outwards, into which the heads of the rivets penetrate during the assembly. To anchor the fastener in the coupling element, it will be fastened, approximately free of gap, in the niches of the coupling element or it will be introduced from

    3/6 open sides of the niches that are located away from the cleaning ruler, and by means of snapping lugs, they are inserted into the niches of the side walls that fit into the slot openings on the side walls of the fastener when assembling. [005] Basically, the coupling element and the fixing element can be produced from plastic. Conveniently, however, the fastener will be made of metal to achieve greater strength, stability and durability. In this way, through the durability of the cleaning blade, a good lateral displacement and high cleaning quality are guaranteed. Advantageously, the fastening element will be combined with a metal coupling with a plastic coupling element.
    [006] In this case, the fixing element is conveniently a folded piece of sheet, the splints protruding from the bottom being folded in the planes of the side walls. In this process, a passage appears at the bottom of the fastening element that corresponds to the splints folded out.
    [007] The present invention covers not only the cleaning blade as a whole, but also the elements of essential constructions, which are the coupling element and the fixing element.
    [008] Other advantages result from the following description of the drawings. The drawing shows an example of carrying out the invention. The design, description and embodiments contain numerous characteristics in combination. The specialist will also conveniently analyze the characteristics separately and combine them in other useful combinations.

    [0014] A blade 10 essentially has a cleaning strip 12 whose rear strip 14 is supported by two elastic rails 16 that penetrate as a support element below the rear strip 14 and in longitudinal grooves - not shown in more detail from the cleaning strip 12. They are also Possible solutions with an elastic track 16 that is normally placed in a longitudinal channel of the cleaning strip 12. In the central region of the cleaning blade 10, a coupling element 20 is attached to the elastic tracks 16, which serves to articulate the cleaning blade 10 with a cleaning arm not shown.
    [0015] The coupling element 20 has two side walls 22 that have conduction profiles 28 in the direction of the elastic rails
    16. In assembled state, they wrap the molar tracks 16 laterally from below and from above. The two side walls 22 of the coupling element 20 are interconnected by a bottom 24 above the conductive profiles 28. This bottom has a longitudinal groove 26 in the direction of the cleaning strip 12 that provides enough space for the rear strip 14.
    [0016] In the inner sides of the side walls 22 of the coupling element 20 there are niches 30 which are open on the side away from the cleaning strip 12 and which have recesses 32 on their internal sides. In the direction of assembly 54, from the open sides of the niches 30, a fixing element 40 will be introduced, whose side walls 42 are interconnected by a bottom 44. The side walls 42 are located in niches 30 of the element

    5/6 coupler 20 in an almost free play position. It is an extension of the side walls 42 in the direction of the elastic tracks 16, in the side walls 42 are formed splints 52 that pass through openings 38 in the bottom 24 of the coupling element 20 and penetrate the cutouts 18 which are reciprocally provided on the external sides of the elastic tracks 16 By means of the cutouts 18, the position of the coupling element 20 will be defined. In this case, it is possible to provide several cutouts 18 longitudinally out of phase, in the same way with the same cleaning blade 10, depending on the case of use, several positions are possible. mounting element of the coupling element 20. To guarantee the stability of the side walls 22 in the region of the niches 30, the side walls 22 are in that area reinforced by thickened sections 36.
    [0017] In its side walls the fixing element has notch openings 50, that is, fitting openings, which cooperate with the grooves 32 in the niches 30 of the side walls 22 of the coupling element 20, so that the fixing element 40 is engaged with the coupling element 20 in the assembled position. In this way, the coupling element 20 is fixed by the conductive profiles 28 in the direction of an elevated axis and transversely to the longitudinal direction of the cleaning blade 10, while the fixing element 40 performs the attachment of the coupling element 20 in the longitudinal direction of the blade cleaner 10.
    [0018] The fixing element 40 can perform other functions, for example, it can receive mounting elements for the articulated connection with the cleaning arm. For this purpose, the fixing element 40 has 42 perforations 46 on its side walls that can serve as hubs for an articulated connection or to which an articulated shaft 48 is attached. This will be conveniently riveted with the side walls 42, with the rivet heads 58 protruding outwards

    6/6 are found in cutouts 34 of the niches of the coupling element 20. [0019] Basically, the fixing element 40 can consist of a suitable random material. For reasons of production resistance and stability, it is convenient that the fastener 40 is a metal component. In this case, it can be a plate component, a ZNAK element, a pressure casting, a pressure casting magnesium piece or a wire structure. Conveniently the sheet piece will be produced in a folding process by stamping, with the splints opening from the bottom, being curved in the planes of the side walls 42. The passage thus informed in the bottom 42 is designated with number 56.
