The reflector bows (23) have on both their end sides a number of reflectors (49) which are permanently connected to the reflector bow. <IMAGE>

Description

At road construction sites, in particular on construction sites of highways and motorways, the traffic flows often have to be diverted in a route that deviates from the usual course of the road. Most of the time, the remaining lane width is too small to separate the traffic flows flowing in opposite directions from each other by wider lane strips with lane dividers of greater height. The same applies to road underpasses and road tunnels, in which the oppositely flowing traffic flows have to be carried out in a limited space, especially if only a single tunnel tube is available. In such cases, guidance devices with a relatively small width and a relatively low overall height are used, as are known, for example, from DE-U-89 12 463.0 or from DE-U-89 15 303.0.

Depending on the length of the roadway section to be fitted with it, this guide device has a more or less large number of base bodies, which have an elongated shape with a generally trapezoidal cross section. They are coupled to one another by means of coupling devices to form a long chain, the parts of which are divided into two groups and mutually arranged at the end regions of the base body. Hood-like guide bodies are attached to the base bodies, each of which has a flat end face in the longitudinal direction of the base body on each side, which is at least partially covered with a reflective film. With these guidance devices, a clearly visible separation of the traffic flows is possible.

With unfavorable road and weather conditions, especially with damp dirt on the road and with little or no moisture, such as in fog very light rain or after the end of a previous rain, it can happen that the passing dirt of the vehicle wheels throws the damp dirt from the road onto the reflective film of the guide body, where it sticks and dries. In it, the guiding bodies lose part of their visual guiding effect.

In underpasses and road tunnels, where the guiding bodies are never exposed to rain that softens and rinses the dirt, the pollution brought in by the vehicles on the guiding bodies can be so strong and permanent that the guiding bodies largely lose their guiding effect. In tunnels with heavy traffic, it can be difficult or impossible to clean the guide bodies with their end faces oriented transversely to the direction of travel with a mobile cleaning device, because neither the work space is available nor the time required to clean each individual guide body is available. In such cases, it may be better to omit the guiding bodies and leave the lane separation to the basic bodies alone.

In all these cases, it is desirable to design the guide device in such a way that its visual recognition, especially in the dark, is improved. This is achieved with a guide device according to claim 1.

Characterized in that at least one reflector bracket is present on the base bodies of the guide device, which is aligned transversely to the longitudinal direction of the base body and which is provided on each end face with a number of reflectors, the visibility of the base bodies for the vehicle drivers passing parallel to them is considerably improved. This applies in particular if the vehicle lighting is switched on in the dark or in poor visibility. This perceptibility remains with unfavorable ones Maintain road and weather conditions for a relatively long time, because at the height of the base body and thus at the height of the reflector bracket, the supply of spray water triggered by the vehicle wheels is relatively strong. Since this spray water usually hits the lower parts of the guide device at considerable speed, the adherence of solid dirt particles is at least reduced, if not completely avoided. Even if the reflector brackets and their reflectors should be heavily contaminated, they can be cleaned with a mechanical washing and cleaning device, which is guided over them in the longitudinal direction of the base body, because of their low height. Such a washing and cleaning device only needs to have relatively small lateral dimensions. In addition, it can be guided over the base body and the reflector bracket at a relatively high relative speed, so that, at most, a slight obstruction of traffic can be expected for a short time.

With an embodiment according to claim 2, the seat of the reflector bracket is reinforced, so that the risk is at least reduced that it is displaced or even torn off by a vehicle wheel sliding past or rolling over it.

An embodiment according to claim 3 improves the visual perceptibility of the reflector bracket by the reflectors additionally present on the side cheeks.

By an embodiment according to claim 4, the good fit of reflector brackets with side cheeks is significantly improved. With an embodiment according to claim 5, a kind of snap closure is created between the side cheeks of the reflector bracket and the base body, through which the reflector bracket is anchored to the base body, depending on the inclination of the abutting contact surface of the projection, the effect of a locking device or even a locking device is achieved. The same applies to an embodiment according to claim 6 for reflector brackets with and without side walls. A development according to claim 7 increases the hold of the reflector bracket additionally, because the retaining ribs present on the guide pin press into the generally cylindrical wall of the hole surrounding the pin in the base body and thus provide additional anchoring.

An embodiment according to claim 8 improves the correct fit on the base body, particularly in the case of reflector brackets without side cheeks.

In an embodiment according to claim 9, the reflector bracket is positively connected to the base body, but can still be removed if necessary.

Through an embodiment according to claim 10, the reflector bracket has a type of ramp surface on both sides, so that a vehicle wheel can roll over it more easily and the risk of bumping or pushing out is reduced.

With an embodiment according to claim 11, the secure fit of the reflector bracket on the base body is greatly improved.

The guide device 20 shown in FIG. 1 has a plurality of base bodies 21, on which some hood-like guide bodies 22 and reflector brackets 23 are arranged.

The base body 21 has an elongated shape with an at least approximately trapezoidal cross section (FIG. 2). The side surfaces 24 of the base body 21 are inclined with respect to the vertical, the angle of inclination in the central part of the side surfaces 24 being approximately 12.5 °. In the direction of the underside 25 of the base body 21, the side surfaces 24 have a concave profile in the end view. The upper side 26 of the base body 21 is essentially flat. In the region of the side edge, the upper side 26 merges into the side surfaces 24 with a greater convex curvature.

The two end faces 27 and 28 are at least approximately perpendicular. In the plan (FIG. 4), the end face 27 has an arc-shaped convex course and the end face 28 has a matching circular arc-shaped concave course.

Each base body 21 is provided with a coupling device 29, by means of which each base body can be positively coupled in its longitudinal direction to an adjacent base body of the same type and can be separated from it again. The parts of the coupling device 29 are divided into two groups, of which the one parts group 29.1 is arranged at the one end region with the convexly curved end face 27 and of which the second parts group 29.2 is arranged in the end region of the base body 21 with the concavely curved end face 28 ( 3 and 4).

Part group 29.2 includes a vertically upward coupling element 31, which is arranged at the end of a holding bracket 32. The bracket 32 is designed as a steel section, one end portion of which is angled at right angles to form the coupling element 31. The parts group 29.1 includes a vertically upward recess 33 on the underside 25 of the base body 21. This recess 33 is matched in terms of its design and arrangement to the coupling element 31 of the parts group 29.2, in such a way that the recess 33 is only slightly larger than that Coupling member 31 is so that only small relative angular movements and equally small relative longitudinal and transverse movements are possible between the two parts. On the underside 25 of the base body 21 there is also a recess 34 which is matched to the retaining bracket 32 of the parts group 29.2.

A coupling groove 35 is provided on the base body 21 in the area of its upper side 26, which has a T-shaped elevation, the T-shape of which is upside down. It is part of a coupling device 36, by means of which the hood-shaped guide bodies 22 are coupled to the base body 21 (FIG. 1). On the guide body 22, two holding ribs (not visible in FIG. 1) are arranged in the foot region, which are designed for the coupling groove 35 after formation and arrangement. As indicated in Fig. 1, the guide body 22 are inserted from one side into the coupling groove 35, after which they are positively coupled to the base body 21 at least in the longitudinal direction thereof, while against the direction of insertion, the coupling acts only by friction.

As indicated in FIG. 1, each base body 21 is equipped with at least one reflector bracket 23. 2 shows one of the possible embodiments of the reflector bracket 23 in more detail.

The reflector bracket 23 has a horizontally arranged main part 37, which rests on the upper side 26 of the base body 21. At the ends of the main part 37 there is a side cheek 38 and 39 on both sides. These side walls 38 and 39 extend from the main part 37 down along the side surfaces 24 of the base body 21. The side cheeks 38 and 39 are shorter than the side surfaces 24.

As can be seen from FIG. 2, the side cheeks 38 and 39 run within a recess 41 and 42, respectively, which are matched to them and which are present in the region of the side faces 24 on the base body 21, and are expediently molded thereon during its manufacture. The depth of the recesses 41 and 42 is greater than the thickness of the side cheeks 38 and 39, so that the side cheeks in the front view (FIG. 2) completely disappear into the recesses 41 and 42.

On the main part 37 of the reflector bracket 23, a guide pin 44 is arranged on its underside 43, and is integrally formed thereon. The guide pin 44 is of circular cylindrical design and is oriented in the direction of a surface normal to the underside 43, as a result of which it is aligned perpendicularly to the base body 21. The guide pin 44 is matched to a through hole 45 in the base body 21, into which it fits tightly.

To support the firm seat of the reflector bracket 23 on the base body 21, a projection 46 and 47 are provided on the inside of each of the two side walls 38 and 39. As can be seen in FIG. 2 for the projection 46, it projects inwards beyond the vertical projection of the section of the inside of the side cheek 38 located above it. The projection 46 is designed as a strip-like projection of the side cheek 38 and is aligned horizontally. It engages in a likewise horizontally aligned recess 48 in the groove base of the groove-shaped recess 41 in the region of the side surface 24 of the base body 21. The projection 46 and the groove 48 form a kind of snap lock for the side cheek 38 and in combination with the corresponding design of the side cheek 39 they form a snap lock for the reflector bracket 23. The upper surface of the projection 46 acts in the manner of a latching device if it is from downward sloping on the outside inwards. In contrast, it acts in the manner of a locking device if it is at least approximately horizontally aligned and can therefore only emerge from the recess 48 as a result of external forces.

As already indicated in FIG. 1 and can be seen even more clearly from FIG. 2, there are a number of reflectors 49 on the main part 37 of the reflector bracket 23, which are embedded in recesses in the two end faces of the main part 37. The reflectors 49 are of a conventional type, as are used, for example, in guide pins.

In the guide device 50 shown in FIG. 5, the base body 51 is also designed to accommodate at least one guide body in the manner of the guide body 22. In addition, it is provided with at least one reflector bracket 53.

The base body 51 is largely identical to the base body 21. In contrast to this, it is only modified with regard to the recesses for the reflector bracket 53. The modification consists in that the side surfaces 54 have no recess and a transverse recess 56 is provided in the area of the upper side 55. Your measure of length, i.e. the dimension measured in the longitudinal direction of the base body 51 is matched to the length dimension of the reflector bracket 53. In the transverse direction of the base body 51, the recess 56 extends over the entire top.

The reflector bracket 53 has a main part 57, at the two ends of which a side cheek 58 or 59 is connected. The two side cheeks 58 and 59 lie on the adjacent side surface 54 of the base body 51 on the outside, so that they are fully visible in the front view (FIG. 5).

The main part 57 and the two side cheeks 58 and 59 are each provided with a number of reflectors 61 which, like the reflector bracket 23, are inserted into matching recesses. So that the reflectors 61 on the main part 57 are always fully visible in the front view, the recess 56 which runs transversely in the upper side 55 of the base body 51 has a depth which is less than the distance of the reflectors 61 from the underside 62 of the main part 57. This recess 56 is shown in FIGS. 3 and 4 on the right side. Since this recess 56 relates to the base body 51, this reference number and the reference number 51 for the base body are set in parentheses.

The reflector bracket 53 also has a guide pin 63 which is designed like the guide pin 44 (FIG. 2). It sits in a circular cylindrical recess 64 of the base body 51.

The side cheeks 58 and 59 of the reflector bracket 53, which rest freely on the side surfaces 57 on the base body 51, can be connected to the base body 51 by inserting a head screw, indicated only by the broken line 65, through a through hole provided in the side wall in question and into a blind hole in the base body 51 is screwed in. This fastening screw is expediently designed as a countersunk screw or at most as a raised countersunk screw so that it projects as little as possible from the outside.

In the guide device 70 shown in FIG. 6, both the base body 71 and the reflector bracket 73 are modified compared to the previously explained embodiments.

The base body 71 has neither in the area of its side surfaces 74 nor in the area of its upper side 75 a recess for the reflector bracket 73. The foot knobs 77 shown on the underside 76 can be integrally formed on the base body 71. It is more expedient to provide corresponding recesses on the underside 76 and to insert the foot knobs 77 therein and, if necessary, to glue them therein. These foot knobs 77 can be made from a different material than the base body 71, in particular from such a material that gives a greater frictional force with the usual road surfaces.

The reflector bracket 73, which is provided in its two end faces with a plurality of reflectors 78, lies freely on the upper side 75 of the base body 71. It has a large guide pin 79 in its center. At some distance of which there are further smaller guide pins 81 and 82 on the right and left, which, like the guide pin 79, are integrally formed on the reflector bracket 73. These smaller guide pins 81 and 82 are also circular cylindrical. They extend into a circular-cylindrical recess 83 or 84, which are matched to this and are provided for this purpose in the area of the upper side 75 of the base body 71.

The large guide pin 81 is also circular cylindrical in its upper part. It is inserted in a circular cylindrical recess 85 of the base body 71 which is matched to this. As previously, this recess 85 is designed as a through-hole so that no foreign bodies such as stones, grit and sand can get stuck therein. In the area of the underside 76, a circular cylindrical extension 86 adjoins the large recess 85.

As can be seen from FIG. 6, two large extensions 87 and 88 adjoin the large guide pins 79 at the bottom. Its outer surface has the shape of a circular cylinder section which is aligned with the guide pin 79. The extensions 87 and 88 taper towards the end. This leaves a gap 89 which increases towards the end between them. The extensions 87 and 88 are made of a material that has a relatively large elasticity, so that the extensions 87 and 88 can be elastically deformed radially inwards.

At the free end of the extensions 87 and 88, an outwardly directed projection 91 and 92 are formed. They protrude radially outward from the outside 93 and 94 of the extensions 87 and 88, their boundary line 95 and 96 (FIG. 8) forming an arc, the radius of which is equal to the radius of the outside 93 and 94 and which is at the same time is equal to the radius of the large recess 85 in the base body 71 (FIG. 6). The contact surfaces 98 and 99 facing the main part 97 of the reflector bracket 73 are aligned horizontally, ie parallel to the underside of the main part 97. They have a distance from the underside of the main part 97 that is equal to the distance that the annular shoulder of the extension 86 from has the top 75 of the base body 71 (Fig. 6). The surfaces facing away from the main part 97 each form a ramp surface 101 or 102, which are at least approximately designed as a section of a conical outer surface. They extend from the protrusion 91 and 92 as far as the outline of the large pin 79 and thus the recess 85 on the base body 71.

As can be seen from Fig. 9, on the main part 97 of the reflector bracket 73, the end faces 103 are inclined slightly inwards, i.e. their angle with the horizontal is less than 90 °. A modification of the reflector bracket 73 can be seen from FIGS. 10 and 11. The two end faces 105 are more inclined on the main part 104. Their angle of inclination with respect to the horizontal is less than 45 °. As a result, the two end faces 105 act more as ramp surfaces, so that a vehicle wheel can roll over it more easily once it has taken the path up to the associated base body.

Due to the greater inclination of the end faces 105, the recesses 106 for the reflectors 107 have an extension 108, at least from the front end of the reflector 107, the peripheral surface of which is either a cylindrical surface with a larger internal width than the recess 106, or more expediently a conical outer surface is, the cone angle can be relatively small. Through this extension 108, the reflectors 107 remain visible from the side at a larger angle than would be the case without the extension.

A modification of the guide pins of the different embodiments of the reflector bracket can be seen from FIGS. 12 and 13. A guide pin 112 is arranged on the underside of the main part 111 and, like the other guide pins, is configured externally as a circular cylinder. The modification is that there are a number of retaining ribs 114 on its peripheral surface 113, which are expediently integrally formed on the guide pin 112. They are aligned parallel to the cylinder axis of the guide pin 112. The holding ribs 114 are sharpened at their free end 115 facing away from the main part 111, so that their backbone 116 approaches the peripheral surface 113 there.
