Abstract

Rubber Panel Systems for Level Crossings at Contact-Working Rubber Engraving Gauge Platforms-Tops of Intermediate and Exterior Panels for Heavy Road Traffic Loads have a convex engraving at the base of a flat rhombus with concave circumferential channels as illustrated in figures (1 and 2) draft a for medium and light road traffic loads engraving at the base of the shape of a rhombus with a shallow sub-engraving of a convex three-sided pyramid bordered by peripheral channels, as illustrated in figures (3 and 4) of the drawing, and for pedestrian crossings engraving at the base of a square with a shallow sub-engraving of convex gates bordered by circumferential pointed concave ducts as illustrated in the figures (5 and 6) of the draft, characterized in that on the contact-working rubber engraving treads-upper and upper panels for heavy road traffic engravings in the form of a flat deltoid with concave channels that intersect and the deltoid along the shorter diagonal and in the center of the cross-section with the longer diagonal is circularly extended in both directions in the direction of the longer diagonal, as illustrated in the figures (22, 23 and 24), so that in the two-part variant of the rubber uppers, a top view is obtained such as illustrated in figure (25) in a variant of uniformity of the rubber uppers has the appearance from above as illustrated in figure (27) of the drawing a for medium and light road traffic engravings in the form of deltoids which are circumferentially followed by concave channels and intersecting the deltoid in the directions of both diagonals and the rectangular triangles thus obtained in the sub-engraving have a convex extended quadrilateral pyramid whose arrangement is "zig-zag" as illustrated in the figures (29, 30, 31, 32, 33, 34 and 35) of the design, and in the variant of uniformity of the rubber uppers is given the appearance of from the top view as illustrated in Figure (36) of the drawing and for pedestrian crossings the engraving is basically a square shape followed by a circumferentially concave channels a sub-engraving contains three geometric bodies in convexity a convoluted quadrilateral pyramid stretched quadrilateral pyramid and a quadrilateral pyramid which are alternately arranged as illustrated in the drawings (38, 39 and 40) so that in the uniformity of the rubber upper there is an image such as (41) of the draft. The application contains 7 additional dependent claims.
