DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(10) FIG. 1 shows a perspective view of a preferred embodiment of an upper side 20 of an angled guide plate 10. The angled guide plate 10 has a basic body 12 and extends along a track direction G. A (imaginary) separation line between a guide region 40 and a supporting region 50 is represented as a dotted line along the track direction G. It can be clearly seen that a thickness d.sub.50 (selected as an example) of the supporting region 50 is bigger than a thickness d.sub.40 (selected as an example) of the guide region 40. The supporting region 50 has a force introduction area 22 configured by two protrusions 26. The protrusions 26 are connected with each other along the track direction G by a web 27. Furthermore, the supporting region 50 has a heel 52 towards the rail (that is not represented here) that increases a stop surface 54 of the basic body 12 that extends substantially perpendicularly to an underside 30. The guide region 40 has two force introduction areas 22 configured as recesses 24 that are placed at a distance along the track direction G the one behind the other. A material thinning or a material recess 70 shaped as a hole is configured between the two recesses 24. The recesses 24 are placed at a distance a24 along the track direction G. The recesses are limited on the upper side 20 towards the supporting region 50 by a transition section 25 that is configured for its part as an elevation with an approximately triangular cross-section.

(11) FIG. 2 shows a perspective view of a preferred embodiment of an underside 30 of the angled guide plate 10 known from FIG. 1 with the basic body 12. The guide region 40 has two bulged engaging portions 32 along the track direction G, these engaging portions having protrusions and/or recesses or grooves 34 on their surface. A recess 24 can be seen in outlines on the front side of the angled guide plate 10 opposite the engaging portions 32. The angled guide plate 10 has corresponding bulges 42 on the outside adjacent to the recess 24. The transition section 25 is configured opposite the bulges. The two engaging portions 32 are placed at a distance a32 along the track direction G. The engaging portions 32 are placed offset to the edge of the angled guide plate 10 by a distance a. For the preferred embodiment represented in FIG. 2, the underside 30 is not configured entirely even but has pockets 31 that make possible an additional saving of material. Force transmission areas 33 that serve as contact surfaces for a not represented (railway) sleeper correspond to the pockets 31.

(12) FIG. 3a shows a lateral view of a schematic diagram of an angled guide plate 10. The wedge shape of the basic body 12 that comprises an upper side 20 and an underside 30 can be clearly seen. It is suggested by the dotted lines that the basic body 12 is essential for determining the thickness d.sub.40 and d.sub.50 of the angled guide plate and that local elevations or recesses or the like are not to be considered for calculating or determining the thickness. The wedge shape is advantageously optimally adapted to the rail 90 or to the rail base. The angled guide plate continues so to speak the shape of the rail base and thus makes an optimal derivation of the forces occurring when a train passes. The imaginary extension of the wedge shape of the angled guide merges almost without a transition into the rail base so that a maximal thickness d50 of the supporting region is adapted to a height of the rail base. The angled guide plate 10 schematically represented in FIG. 3a has a protrusion 26 on its upper side as well as a force introduction area 22 configured as a recess 24. A bulge 42 is adjacent to the recess 24. An engaging portion 32 that extends away from the upper side 30 is formed below the recess 24. A supporting region 50 has a stop surface 54 on its end orientated towards a rail (that is not represented here). The vertical dotted line indicates a supporting region 50 and a guide region 40.

(13) FIG. 3b shows the schematic diagram known from FIG. 3a in a mounting situation. A (tension) clamp 80 is placed on the angled guide plate 10 in a recess 60 by a (sleeper) screw 82. The (tension) clamp 80 bears on the protrusions 26 and the recess 24. A rail 90, in particular a rail base, that is locked from above by the tension clamp is placed on the stop surface 54.

(14) FIG. 4 shows a schematic diagram of a preferred embodiment of a track arrangement. An angled guide plate 10 is represented in a section so that a recess 60 for arrangement, for example, of a corresponding fastening means (that is not represented here) is possible. The angled guide plate 10 is placed with an underside 30 on a (railway) sleeper 92 that is represented crosshatched here. An engaging portion 32 of a guide region 40 of the angled guide plate 10 engages into a corresponding form of the (railway) sleeper 92. The angled guide plate 10 shows on an upper side 20 thereof a bulge 42 for arranging on the (railway) sleeper 92. The angled guide plate 10 is placed over a stop surface 54 on a rail 90 that extends along a track direction G. The rail 90 stands on an intermediate layer 93.

(15) FIG. 5 shows a view of a preferred embodiment of an angled guide plate 10 transversely to a track direction G with view from a guide region to a supporting region (here without reference numerals). Two engaging portions 32 that have respectively three grooves 34 are clearly to be seen. The grooves 34 are placed at an equal distance from each other, wherein they are however offset inwards with respect to the respective engaging portion 32. Furthermore, a force introduction area 22 that is configured by two recesses 26 and comprises two bearing surfaces 26 is shown. The engaging portions 32 merge directly into bulges 42 attached thereto.

(16) FIG. 6 shows a lateral view of a further preferred embodiment of an angled guide plate 10. Again the wedge shape of a basic body 12 that has an upper side 20 and an underside 30 and that tapers from the supporting region 50 to the guide region 40 can be recognized. A force introduction area 22 configured as a recess 26 extends away from the upper side 20. The supporting region 50 is limited towards a rail (that is not represented here) by a heel 52 with a stop surface 54. A pocket 31 is also placed in this area on the underside 31. An engaging portion 32 is configured opposite a recess 24. The guide region 40 ends in a bulge 42 that in its part seamlessly merges into the recess 24. The recess 24 is limited towards the upper side 20 by an approximately triangular transition section 25.

(17) FIG. 7 shows a schematic top view of an upper side 20 of a trapezoid configured angled guide plate 10. The different lengths of the supporting region L50 and of the guide region L40 that contribute to the wear reduction of the angled guide plate are clearly to be recognized. A basic body 12 comprises a recess 60 as well as a material recess 70 with the shape of a hole. The representation of further characteristics has not been added in this illustration.

(18) FIG. 8 substantially shows the embodiment known from FIG. 7, wherein an engaging portion 32 is formed in that an underside 30 merges in a first radius therein. One or several recesses are formed in that the underside merges in a second radius R2 into the engaging portion, wherein the second radius is bigger than the first radius.
