• Control system in particular for securing traffic routes
• the invention relates to a control system, in particular for securing traffic routes
• the guidance system can be used to separate or secure lanes at construction sites or squares, or to separate planting islands or planting cubes set up in the area of traffic routes.
• Such a guidance system can also be used to separate Lanes on motorways or in streets or for narrowing lanes, for example for the purpose of speed reduction.Finally, such a guidance system can also be used within large halls to also create traffic routes there, namely lanes for so-called go-karts or similar motor-driven vehicles
• the guidance protection system according to this publication is essentially formed by a plurality of guidance pieces arranged one behind the other and connected to one another. These guide pieces are designed in such a way that the end of a first guide piece can be connected to the beginning of the next guide piece following it. In order to make do with a single shape of the guide pieces, they have a cone-shaped attachment at one end and a bearing-eye-shaped attachment at their other end to accommodate the respective pin on die Both approaches are designed or arranged on the guide piece in such a way that the pin of a subsequent guide piece is inserted from above into the bearing-eye-shaped approach of a preceding guide piece
• a self-contained area is to be delimited with the above-described guidance protection system, which can be done, for example, to delimit a traffic island, a planting area or the delimitation of a roadway for a go-kart racing route, difficulties arise with the guidance pieces of the above-described guidance protection system to close such an area or the racetrack either a specially designed end piece is required, or the last guide piece can only be installed under difficult conditions.
• the invention has for its object to provide a generic guide protection system which, while ensuring uniform guide pieces, on the one hand enables rapid replacement of damaged guide pieces and on the other hand is flexible in its routing,
• each guide piece has a central piece which is essentially parallel to the direction of the traffic path and hastily deformable transversely to its longitudinal axis, and a plurality of supports extending transversely to the central piece with support surfaces arranged symmetrically to the central piece are provided on the central piece are, which are arranged to achieve the deformability of the central piece at a mutual distance from each other, wherein two adjacent guide pieces can be detachably connected to each other by means of a coupling piece engaging in the spaces between the supports
• the corresponding curve shape is composed of a plurality of guide pieces, this shape can be fixed simultaneously with the coupling piece connecting two adjacent guide pieces, the two flanges of the coupling piece engaging in the intermediate spaces located between the supports.
• the arrangement of gaps between the individual supports gives the guide piece its ability to bend on the one hand, and on the other hand, the formation of a curve shape on the side of the guide piece facing the carriageway results in an almost uninterrupted contact surface for the outside wheels of the vehicle.
• the individual supports or the corresponding guide piece can thus elastically absorb lateral forces of the vehicle, the guide piece deforming elastically under the influence of such lateral forces and being able to return to its starting position after the lateral forces have ceased to exist.
• a production-technically simple design of the guide pieces results from the central piece and the supports of each guide piece being formed in one piece.
• each guide piece has in the region of its upper end at least at its two front-side end areas a recess which is essentially parallel to its longitudinal axis and which, in a preferred embodiment, can extend over the entire length of the guide piece.
• the guide piece can be shortened at any point and inserted as an end or intermediate piece in the guide protection system.
• An advantageous embodiment of the coupling piece results from the fact that it has a web engaging in the recess of the guide piece with flanges arranged at its front ends.
• To connect two guide pieces it is therefore only necessary to place the corresponding guide pieces close together and the two flanges of the Push the coupling piece into the adjacent spaces between the guide pieces until the web of the coupling piece is within the recesses of the guide pieces.
• the two flanges protruding into the spaces between the two guide pieces secure the guide pieces in their longitudinal direction, while the web engaging in the recesses secures the guide pieces in the direction transverse to their longitudinal direction.
• the guide pieces can be used together or with guide pieces End pieces or intermediate pieces are connected to one another without the aid of separate fastening means, such as screws.
• each support has a run-up surface which begins with an inclined surface in the region of its support surface and continues in itself in a convexly curved surface.

• the guide piece 1 shows a guide piece 1 of the guide protection system in a curved shape.
• the guide piece 1 can take either the curved shape shown in FIG. 2 or a straight shape as shown in FIG. 3 within the guide protection system.
• Straight and curved guide pieces can be arranged in any order, which can then be connected to one another with the aid of coupling pieces 2. Since all the guiding pieces 1 and also all coupling pieces 2 of the guiding protection system each have an identical design, the following description is limited to one of these guide pieces or one of the coupling pieces
• the guide piece 1 (FIG. 4) has a middle part 3, which is oriented in the longitudinal direction of the guide protection system and is made of an elastically deformable material.
• the central part 3 has a preferably rectangular cross section, so that it is relatively easily elastically deformable transversely to its longitudinal axis, but is rigid parallel to it.
• supports 4 are provided at relatively short distances, which embrace the middle part 3 in their upper region and have support surfaces 5 arranged symmetrically to the middle part 3 in their lower region.
• the middle part 3 and the supports 4 are formed in one piece
• a recess 6 is provided on the connection piece 4 above the central part 3.
• the recess 6 can extend over the entire length of the guide piece 1.
• the entire guide protection system is very flexible as far as to form end or Intermediate pieces only have to be separated from a guide piece 1 by a corresponding length, the separated lengths being able to be connected to a guide piece 1 in the same way as the guide pieces 1 themselves
• the sockets 4 have in their lower region run-on surfaces 7 for the vehicle, which begin in the region of their support surfaces 5 each with an inclined surface and continue in convexly curved surfaces.
• the support surfaces 5 are also arranged symmetrically to the central part 3
• the coupling pieces 2 which serve to connect two guide pieces 1 with one another or a guide piece 1 with an end piece or intermediate piece essentially correspond to the shape of a U and have a web 8 and two lateral flanges 9 which are located on the end faces of the web
• the parts to be connected are placed with their end faces close to one another.
• the coupling piece 2 with its two flanges 9 is placed from above as far over the connecting pieces of the two with each other connecting parts guided until the web 8 is within the recesses 6 of the guide pieces 1 to be connected.
• the two flanges 9 of the coupling piece 2 corresponds to an integral multiple of the width of a support 4, the two flanges 9 take over the securing of the connection of the guide pieces 1 in the longitudinal direction of the guide protection system, while the web 8 projecting into the recesses 6 secures the Leitschutzsystem takes over in the direction transverse to its longitudinal direction.
• the guide pieces 1 required to form the loop can be introduced onto the piece of the circular course which has been opened since then. Since the loop has curves, the guide pieces 1 are elastically deformed according to these curves before or during their introduction into the guide protection system, ie their originally straight course is bent accordingly. The guide pieces 1 deformed in this way are then connected to one another or to the open ends of the previous round course by introducing the coupling pieces 2. Insofar as the curvature that occurs when the guide pieces 1 are deformed does not fall below a certain minimum radius, the shape of the loop formed in this way is secured by the coupling pieces 2. If necessary, the curve shape achieved can also be fixed to the floor by fastening individual guide pieces 1. Coupling pieces 2 are also conceivable for fixing the curve shape use, in which the distance between the two flanges 9 corresponds to the sum of the width of, for example, 4 supports 4 and the two spaces enclosed by them.
• FIG. 5 it can also be seen that the part of the guide protection system shown there is formed by a total of three guide pieces, namely a rectilinear guide piece 1, a first arcuate guide piece 1a and a second guide piece 1b adjoining it.
• Fig. 5 also shows that the respective last support 4e and the first support 4a of the guide pieces 1, 1a and 1b both directly abut each other on the inner radius of the carriageway and on the outer radius facing away from the carriageway and are directed parallel to one another, while the remaining supports 4 of the curved guide pieces 1a, 1b are directed exactly radially and have a mutual distance on the outer radius which is somewhat larger than the mutual distance of the supports 4 on the straight guide piece 1.
• the design of the guide pieces 1 according to the invention is suitable for delimiting both the outer and the inner edge of the carriageway from circular courses, and in particular to absorb the lateral forces arising at the outer radius and then to deform again. Since, for example, the guide pieces 1 to be arranged in the area of the inside radius of a bend only serve to delimit the roadway, i.e. they do not have to absorb or intercept forces, it is also possible to provide guide pieces in these areas which are only provided with a support on one side of the central part.
