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 oppositely flowing traffic flows by wider lane strips with lane dividers of greater height and greater width. Therefore, guidance devices of smaller width and usually also of lower overall height are usually used there. These control devices are intended to meet a whole range of requirements. They should have a good visual guiding effect. They should damage the vehicles as little as possible, from which they are hit or run over. They should be stable and stationary. In addition, they should be as resistant and durable as possible.

Among the various embodiments of such guide devices, there is a guide device (DE-U 83 37 204) with a hood-like guide body with a rectangular outline, which is connected to a base plate or base plate via a coupling device. As one part, a bead with a rounded cross-sectional shape is present at the lower edge of the two wall parts on the broad sides of the guide body. There are two matching grooves on the base plate.

If a tilting moment is exerted on this guide device as a result of wind forces or when the guide body is bypassed, the bead is raised in its groove on the force introduction side. Due to the inevitable dimensional tolerances, relative movements occur. The rounded cross-sectional shape of the bead causes a not inconsiderable wedge effect, which leads to further elastic deformations of the bead and the groove parts and to corresponding further relative movements of these parts leads among themselves. When the guide body swings back, these relative movements take place in the opposite direction. The frequent gusts of wind generated by the passing vehicles cause vibrations on the guide bodies, which, together with the forces that occur, lead to constant frictional movements between the bead and the groove. Since fine crystalline street dust is always present, these vibrational movements result in a relatively rapid wear of the parts of the coupling device. The greater the wear, the greater the vibrational movements. The destruction of the coupling device is therefore progressive.

When driving around or passing over such a guide device, folding and kinking processes occur on the guide body, which are somewhat smaller in the area of the coupling device and therefore all the greater in the actual guide body. Experience shows that such guiding bodies are destroyed after a relatively short period of time. Then the guide body either remains on the ground, or it is torn off as a whole or in part from the base plate and flung away. In any case, it loses its conductivity. In addition, the guide body can no longer be erected again. It needs to be replaced.

In order to avoid this rapid destruction of the guide body, it was additionally proposed to arrange the parts of the coupling device on the guide body on a baseboard which is connected to the guide body by a kind of push-button connection. The skirting has a predetermined breaking point that breaks when the guide device is passed over, so that the guide body itself is relieved of the folding and bending forces. But it is precisely this predetermined breaking point that leads to the fact that the guide body is turned over the first time the guide device is bypassed or passed over and remains on the ground. The very important durability of the control device is virtually prevented here by constructive means. Apart from the fact that it is the control device suddenly loses its guiding effect, it only helps the guiding body little if it is knocked down immediately if it is run over more often because of the lack of guiding effect on the ground. The same conditions also occur if the predetermined breaking point is not very weak. Then the push-button connection between the baseboard and the guide body becomes the weakest link in the coupling device, which breaks first. There is also the risk that when the push-button connection is torn off, the guide body is also damaged or destroyed and it can then no longer be used and must be replaced as a whole.

The stated invention has for its object to provide a guide device which has a very good guiding effect, which has a low damaging effect for a vehicle approaching or driving around it, which is as stable and stationary as possible and which achieves a long service life and, if possible, Can easily be removed at the end of their service life.

This object is achieved by a guide device with the features specified in claim 1.

In this guide device, there is a circumferential foot at the lower end of the guide body, on which ribs are formed as part of the coupling device on the outside of the broad side of the guide body. If a tilting moment is exerted on the guide body, the rib located on the pulling side engages a large area on the counter surface of the groove in the footplate which is matched to it. There are no squeezing processes that are unavoidable in the case of thickening with a rounded bead profile. In addition, the foot has a high dimensional stability due to its all-round closed shape and, above all, it is very torsionally rigid and rigid.

The two recesses present above the foot in the wall areas of the narrow side of the guide body ensure that the remaining flat wall areas on the broad side of the guide body act like two leaf springs connected in parallel. Due to the flatness of these wall parts, only simple bending processes occur in them and not spatial folding and folding processes, which are inevitable when the hood-like guide body is closed. The two leaf springs connected in parallel have a very large restoring force, to which the elasticity of the form of the adjoining part of the guide body makes a considerable contribution. Because the two wall areas on the narrow side of the guide body have the shape of a cylindrical outer surface or a conical outer surface with a semicircular plan projection, only simple bending processes occur when the two wall regions of the broad side are brought closer together when the guide body is folded down. Here, too, spatial folding and kinking processes are avoided in the wall areas of the narrow side, since, due to the recesses, they no longer connect directly to the foot but are only indirectly connected to the foot via the two flat wall areas on the broad side of the wall body. Even when there is a force on the side, the narrow sides give way elastically without folding and kinking.

If these guide bodies are driven around or approached, they simply fold over, since the two flat wall areas on the broad side act as bending joints. As soon as the force that has knocked them down and possibly pushed them down to the ground stops, they suddenly jump up again and return to their original upright position. The good guiding effect of the guiding device remains unrestricted for a very long time.

Advantageous refinements of the guide device according to claim 1 are specified in the subclaims, which support the guide device in different ways in fulfilling the requirements.

An embodiment according to claim 2 makes it possible to manufacture the holding plate with the associated parts of the coupling device from a material which has a higher dimensional stability and dimensional accuracy than the material of the rest of the base plate. On the one hand, this ensures a good fit of the guide body. On the other hand, it is thereby possible, without impairing the accuracy of shape of the coupling device, to use a material of lower quality and therefore generally also of lower cost for the remaining part of the base plate. For example, recycled plastic waste can be considered.

An embodiment according to claim 3 ensures that the guide body can only be displaced with a certain force relative to the base plate or base plate. This prevents even small lateral forces, for example when a vehicle wheel rubs against the side, from displacing the guide body relative to the base plate or base plate or even separating it from it.

In an embodiment according to claim 4 is achieved by the stop that the guide body is always inserted into the grooves of the base plate without great attention from the operating personnel to the correct point.

An embodiment according to claim 5 facilitates the insertion of the base of the guide body into the grooves of the base plate or base plate up to the correct mutual position even when there are relatively close tolerances between the parts of the coupling device.

An embodiment according to claim 6 gives the base of the guide body a particularly high dimensional stability. This reduces the elastic deformations of the foot when starting or bypassing the guide body. On the one hand, this reduces the risk that the base of the guide body will be torn out of the grooves in the base plate or base plate. On the other hand, the elastic deformations are shifted even more strongly to the two wall regions on the broad side of the guide body which act as flexible joints and flexible springs.

With an embodiment according to claim 7, it is prevented that when a vehicle drives onto the guide body, the wall area on the opposite side on the broad side of the guide body bulges outward and thereby prevents the flat wall area from buckling and bending above the foot.

An embodiment according to claim 8 avoids that a vehicle wheel rolling over the base plate / base plate and the folded guide body is caused to jump and / or that parts of the guide body are pressed in between the two ribs by this edge and are thus deformed more.

An embodiment according to claim 9 improves the grip of the base plate or base plate, as a result of which it can be moved even less easily than is already the case. This embodiment is particularly suitable for such guidance devices if the embodiment with the base plate that can be glued to the floor is not available for long-term use of the guidance device. If necessary, for example when changing the location of the guide device, the adhesive sheets can be easily replaced.

In an embodiment according to claim 10, the foot sill has such a large weight due to its dimensions that the mere fact that the danger of being pushed away when a vehicle is driven sideways is very low. For this reason, gluing to the roadway can generally be dispensed with in the case of the threshold, as a result of which all the disadvantages of the gluing are eliminated by themselves. The coupling device allows a large number of guide devices to be connected to one another in a closed row. As a result, these guidance devices act as continuous road dividers. Characterized in that each guide device is connected to the adjacent foot sleepers via the front coupling devices, the adjacent foot sleepers also contribute to securing the position of the foot sleeper that is touched by a vehicle wheel.

The height chosen for the threshold and the relatively low inclination of the side walls on the one hand have a sufficiently large visual guiding effect, which, when driving a vehicle passing by, triggers the effort not to run over the threshold if possible. On the other hand, the threshold is not so high that a vehicle, for example a passenger car, cannot safely drive over the threshold. In particular, the risk is avoided that the passenger car will skid, as can occur at higher thresholds, which are occasionally used as road dividers. In contrast to these higher thresholds, the danger that a passenger vehicle traveling over it sits on it due to its relatively low ground clearance is also avoided in the guide device with a threshold. It would instantly become unable to drive and unable to steer, and would represent a sudden obstacle to the flow of other traffic. The danger to the occupants of such a stuck passenger car is particularly great because on this vehicle, as a rule, on both sides the rest of the traffic flows close by, so that it is impossible for the occupants of the stuck passenger car to leave the vehicle.

The relatively low height of the foot sill also enables a vehicle wheel to be rolled over at a somewhat larger angle to easily roll over it without the vehicle getting into excessive rocking movements. This applies to both going over and going over the threshold. This means that a vehicle that has involuntarily driven over the foot sleepers with the wheels on one side of the wagon can be steered back onto the original roadway without great difficulty and without greater risk of skidding.

With a configuration according to claim 11, a relatively simple to produce coupling device for coupling the foot sills together to a longer chain is created, which is very robust and therefore very durable. In addition, the foot thresholds of the guide device can be designed relatively quickly and easily, and the foot plates can already be coupled to one another. After that, the completion of the control device only needs to be put on, i.e. of pushing in, the hood-shaped guide bodies on the foot sills.

A further development according to claim 12 deliberately limits the articulation of the coupling device. This 'stiffening' of the joints considerably enhances the support of a stripped threshold by the neighboring thresholds.

An embodiment according to claim 13 makes it easier to roll a vehicle wheel up onto the threshold. As a result, the threshold is beyond its own weight additionally burdened and thus additionally pressed against the floor. This further reduces the risk of the foot sill shifting laterally. Due to the shape of the foot sill, a vehicle wheel rolls up and, if necessary, rolls over in a steady motion sequence without large height movements, so that there are no major repercussions on the vehicle itself, in particular no major impairments of the steering ability and straight running. Even the complete rollover and subsequent rolling back of the vehicle wheel takes place in a relatively gentle sequence of movements, so that there are no major impairments to the driving behavior of the vehicle. This is of great importance because, for example, in heavy, two-lane column traffic on one side of the guidance system it can happen that a truck traveling in the right lane or its trailer may come so close to a passenger car traveling in the left lane that the driver of the passenger car involuntarily or necessarily makes an evasive movement to the left in order to avoid an alleged or actually impending collision and thereby roll the left wheels of his vehicle onto the guide device or roll it over completely. Then, as quickly as the situation permits, he can completely steer his vehicle back into its lane by making slight steering movements. These relationships are supported by further training according to claim 14.

In an embodiment according to claim 15, the total weight of the guide device is concentrated on the surface areas of the foot knobs. This has resulted in a corresponding increase in wing loading. The fact that a material is used for the foot pimples, which has a lower hardness than the material of the base body, ensures that the footprint of the foot pimples due to their greater elasticity more in the small Unevenness of the floor deformed at the place of use and thereby an additional positive connection between the foot knobs and the floor occurs, which increases the displacement resistance of the guide device considerably, so that it is even more stationary than in the normal version. In a further development according to claim 16, in which the foot knobs are each formed by an insert which is inserted into a matching recess in the foot sill, the insert is secured against lateral displacement solely by this form fit. This applies both to the use of the threshold on the street and to the handling of the thresholds.

In a further development according to claim 17, the increase in the security against displacement is achieved in that the material used for the application results in a rough surface due to its starting material and its manufacturing process, which enables a good form fit with the unevenness of the floor that is always present. With the development according to claim 18, the same effect is achieved in that the material of the inserts on the one hand is very flexible and can thereby easily deform into the unevenness of the floor and on the other hand that it has a high tensile strength or toughness that prevents that despite the resilience of the material, the material parts of the insert which have penetrated into the depressions of the base are sheared off when a lateral force occurs. This increases the stability and durability of the guidance system considerably.

An embodiment according to claim 19 increases the dimensional stability of the guide body. The handle hole with a handle strip attached to it at the upper end of the guide body allows the guide bodies to be grasped and transported and also easily moved by hand. The continuous slot in the handle bar prevents one at the bypassing or driving over the guide Underside of the vehicle protruding down part hooks on the handle and possibly tears it off or that this part of the vehicle itself may be damaged or even torn off.

An embodiment according to claim 20 ensures that the guide body can not be easily separated from the base plate / base plate or foot sill, even against the direction of insertion, if it is pushed or struck by a vehicle wheel in this direction.

The guide device 20 shown in FIG. 1 has a guide body 21 and a base plate 22. The guide body 21 and the base plate 22 are detachably connected to one another by means of a coupling device 23.

The guide body 21 is designed as a hollow body which is open at its lower end. This gives it a hood-like appearance. The guide body 21 has four wall regions which adjoin one another in the circumferential direction. These are the two diametrically opposed wall areas 24 and 25, which have a larger horizontal extent, and the two wall areas 26 and 27, which are also diametrically opposed to one another and which have a smaller horizontal extent.

The two wall areas 24 and 25 on the broad side of the guide body 21 are at least approximately flat. They are inclined towards each other in the upward direction so that they are at the greatest mutual distance at the foot 28 of the guide body 21 and that they approach each other at the upper end so far that they finally touch each other (FIG. 2). The uppermost length section 31 of the guide body 21 is formed with full walls. In this length section 31 there is a grip hole 32, by means of which the guide body 21 can be grasped and raised and also otherwise handled.

The two wall areas 26 and 27 on the narrow side of the guide body 21 are formed as sections of a slim conical jacket, the plan projection of which at least approximately represents a semicircular ring surface. These cone-shaped wall areas 26 and 27 have a somewhat greater wall thickness than the two wall areas 24 and 25 on the broad side of the guide body 21. This improves the uprighting behavior of the guide body 21, so that it straightens up again once it rolls over a vehicle wheel was knocked over.

In order to improve the bending behavior of the guide body 21, the two wall regions 26 and 27 each have a recess 33 and 34 on the narrow sides of the guide body 21. These recesses 33 and 34 are in one above the foot 28 High altitude, in which they are located completely above the top of the bottom plate 22. The recesses 33 and 34 have a height which is somewhat less than the distance between the two flat wall regions 24 and 25. Each of the two recesses 33 and 34 extends in the circumferential direction at least approximately as far as the curved wall area on the narrow side of the guide body 21 in question, ie from one transition point to the adjacent flat wall area 24 to the other transition point to the other flat wall area 25 3, the recesses 33 and 34 are sharp-edged at the transition point to the foot 28, whereas they are rounded at the transition point to the curved wall area 26 and 27, respectively.

In the height region of the guide body 21 above the recesses 33 and 34, a number of stiffening elements 35 are formed in the wall areas 24 and 25 on the broad side of the guide body 21. In the embodiment of the guide body 21 shown in FIGS. 2 and 3, they are designed as ribs 36 which are formed on the outside of the wall regions 24 and 25. They are aligned vertically. Their height is approximately a quarter of the total height of the flat wall areas 24 and 25 without the foot 28. The ribs 36 are higher at their upper end and continuously merge into the flat wall areas 24 and 25 at their lower end because they are less inclined to of the vertical have as their two wall regions 24 and 25, but the back of the ribs 36 also have a certain inclination in relation to the vertical in the order of magnitude of the usual formation angle.

In the embodiment of the guide body 21 'shown in FIGS. 9 and 10, the stiffening elements 35' have the shape of bead-shaped indentations of the otherwise flat wall regions 24 'and 25'. They are also aligned vertically.

In the case of the indentations 37, the greater depth is at the bottom, whereas in the upward direction they continuously merge into the flat but obliquely extending wall area 24 ′ or 25 ′.

Due to the fact that in the case of the stiffening elements 35 'designed as indentations 37', the greater resistance to deformation is in the region of their greater depth, their stiffening effect is closer to the recesses 33 and 34 (FIG. 3) than is the case with the ribs 36. As a result, the kink behavior of the guide body 21 in the region of the recesses 33 and 34 is favored even more. In addition, the buckling behavior of the wall regions 24 'and 25' in the region of the indentations 37 is more favorable because there is no increase in wall thickness, as is the case with the ribs 36.

The base plate 22 has a rectangular plan area (FIG. 4), the width of which is approximately 160 mm and the length is between 200 and 250 mm. It has a height of approximately 20 mm. The underside 38 of the base plate 22 is at least partially flat. When the base plate 22 is used, the flat and self-contained areas of the underside 38 are provided with an adhesive, by means of which the base plate 22 is glued to the floor at its place of use.

The top 39 of the base plate 22 is also flat, at least in some areas. This applies at least to the central part 41 of the base plate 22 (FIG. 5) and to the length sections 42 and 43 adjoining it. These two length sections 42 and 43 are each followed by a ramp section 44 and 45, in which the height of the base plate 22 is from its maximum value of about 20 mm in the middle part 41 decreases to a minimum value which it still has on the two edges 46 and 47 on its narrow sides.

As can be seen in particular from FIG. 5, the base plate 22 in the ramp sections 44 and 45 each has a large-area recess 48 and 49, in the plan area of which the base plate 22 has an at least approximately constant wall thickness. In the longitudinal direction of the base plate 22, these recesses 48 and 49 each end at a relatively steeply oriented wall surface 51 and 52. On these wall surfaces 51 and 52 there are a number of circular recesses, into each of which a reflector 53 is inserted (FIGS. 5 and Fig. 6).

The base plate 22 is provided in the plan area of its middle part 41 on the underside with a number of recesses 54 (FIGS. 5 and 8), between which there are narrow wall parts in the manner of stiffening ribs. As a result, a larger, contiguous accumulation of material is avoided in the central part 41, which could lead to warpage when the material shrinks.

The coupling device 23 includes two retaining ribs 56 and 57 on the guide body 21 (FIGS. 2 and 3) and two grooves 58 and 59 on the base plate 22 (FIGS. 4 and 5).

The two holding ribs 56 and 57 are formed on the base 28 in the region of the two broad sides of the guide body 21 on the outside. The two holding ribs 56 and 57 have a rectangular cross section. At its front end in the direction of insertion, which is shown on the right in FIG. 3, the holding ribs 56 and 57 have a ramp surface 62 which is inclined downwards from their upper side 61.

The holding ribs 56 and 57 and the adjoining wall part 63 and 64 of the foot 28 each have an L-shaped cross-sectional area (FIG. 2). Accordingly, the two grooves 58 and 59 also have an L-shaped cross-sectional area on the base plate 22 (FIG. 5). The groove 58 consists of the two groove parts 65 and 66 and the groove 59 from the two groove parts 67 and 68 together. Of these, the groove parts 65 and 67 are matched to the holding ribs 56 and 57 on the foot 28. The groove parts 66 and 68 are accordingly matched to the wall parts 63 and 64 of the foot 28. This matching of the cross-sectional areas is expediently carried out in such a way that, taking into account the material elasticity of the guide body 21 and the base plate 22, there is a floating fit between these two parts.

So that the guide body 21 comes into the correct operating position when it is joined to the base plate 22 without further action, in the tear-open area of the two retaining ribs 56 and 57 of the base 28 each have a wall part 71 or 72 (FIG. 4) of the base plate 22 closes the groove part 65 or 67 at the end. These wall parts 71 and 72 thus represent a stop for the holding ribs 56 and 57. They are therefore arranged on the base plate 22 at the point at which the end face 73 of the holding ribs 56 and 57 is when the guide body 21 is in its operating position on the base plate 22 occupies.

Since, when the guide body 21 and the base plate 22 are joined, the central part 41 of the base plate 22 is located in the path of movement of the leading narrow side of the foot 28, a recess 74 is present at this point of the foot 28, the projection of which is matched to the projection of the central part 41 . On the opposite narrow side, the wall surface of the foot 28 is not interrupted.

As can be seen in particular from FIG. 2, the foot 28 has a greater wall thickness all around than the remaining part of the guide body 21. This is because at least the lower part of the foot 28 together with the holding ribs 56 and 57 form part of the coupling device 23 forms between the guide body 21 and the base plate 22 and it must therefore have a higher resistance to deformation than the rest Part of the guide body 21, which is supposed to have a particularly large elastic deformability in the height region of the cutouts 33 and 34 on its two narrow sides. The more the foot 28 and the retaining ribs 26 and 27 formed on it have their shape and thus their tight fit in the grooves 58 and 59 of the base plate, the more likely the correct bending of the guide body 21 and an equally complete and quick re-erection of the guide body 21 is achieved 23 maintained.

In the guide device 80 shown in FIG. 11, a guide body 21 is used as previously explained. It is coupled to a base plate 81, which is generally set up freely on the floor at the location of the guide device 80.

The foot plate 81 has a rectangular plan shape. It has a length of approximately 500 mm and a width of approximately 250 mm. Its top is shaped like a truncated pyramid, the side surfaces of which are very inclined. In the middle there is an approximately flat end surface, which is about 70 mm above the ground.

As can be seen from FIGS. 13 to 14, a plate is formed in the upper part of the base plate 81 which is largely identical or at least similar to the base plate 22 and which is referred to below as a holding plate 82 for better distinction. As can be seen from FIG. 13, the holding plate 82 differs from the foot plate 22 only in that the ramp sections 44 and 45 present there are shortened to two short floor parts 83 and 84, and in that on the steeply rising transition surface from these floor parts 83 and 84 no reflectors are attached to the central longitudinal section of the holding plate 82, because this part of the Holding plate 82 is embedded in the material of the remaining part of the foot plate 81. Since, moreover, the holding plate 82 is the same as the base plate 22, reference is made to the explanation thereof.

By using the finished holding plate 82, on which all parts of the coupling device 23 are present, the shape for the foot plate 81 can be kept simpler overall. It also makes it possible to use different materials for the holding plate 82 and for the remaining part of the foot plate. Recycled plastic waste, so-called recycling plastic, can easily be used for the latter part, as a result of which the costs for the base plate 81 can be reduced very much overall without the functionality of the coupling device 23 being impaired.

The base plate 81 is provided on its underside with a recess 85, which is designed as a negative form to the section of the upper side of the base plate 81 located in the same plan area, so that the recess 85 can serve as a stacking trough. This allows a plurality of foot plates 81 to be stacked one on top of the other, keeping each other in the correct parallel orientation to one another.

In addition to the stacking trough 85, there are a whole series of further recesses 86 on the underside, all of which are oriented perpendicularly and whose wall surfaces are inclined with a draft bevel sufficient for the material used. Larger material accumulations within the base plate 81 are avoided with these recesses 86.

The base plate 81 has a largely flat bottom surface 87 on its underside. In the region of the corners and in the longitudinal center of the base plate 81, base studs 88 are formed with which the foot plate 81 rests on the floor. As a result, the floor surface 87 has a certain distance from the floor, so that, for example, rainwater flowing to the floor plate can flow underneath it and does not first have to flow around it.

As can be seen from FIGS. 15 and 16, there are flat recesses 89 with a circular base area on the underside of the base plate 81. In each of these recesses 89, an adhesive plate 91 is inserted, the thickness of which is somewhat greater than the depth of the recesses 89. The adhesive plates 91 have a circular ring shape, i.e. they have a circular through hole 92 in their center.

The adhesive plates are provided on both flat sides with an adhesive layer 93 and 94, respectively, which are indicated in FIG. 15 as a dashed line. The adhesive on the top of the adhesive plate 91 is selected so that it gives a good adhesive effect with the material of the base plate 81 present in the area of the recesses 91. The adhesive on the underside of the adhesive plate 91 is selected so that it gives a good adhesive effect with the floor at the location of the foot plate 81. Both adhesive layers 93 and 94 are expediently covered with a protective film as long as the adhesive plates 91 are still loose. Before gluing into one of the recesses 89, the protective film is removed from the upper adhesive layer 93 and the adhesive plate is glued into the recess 89. The protective film on the adhesive layer 94 located below remains in place until the exact location of the individual footplate 81 is fixed, then the footplate can be tilted to the side with the guide body 21 already inserted, the protective film removed from the adhesive layer 94 located below and the entire guide device 80 is erected and the foot plate 81 is pressed firmly onto the floor.

If the foot plate 81 is later removed from its installation location, it cannot be ruled out that part of the adhesive layer 94 located below will become detached from the adhesive plate 91 and get stuck on the floor, or that this adhesive layer 94 may become part of the adhesive due to adhering loose floor parts or dirt parts Adhesive effect loses. Then a simple tool, such as a screwdriver, can be inserted into the through hole 92 and with its help the adhesive plate 91 can be levered out of the recess 89 and, if necessary, even broken out. If necessary, the recess 89 can be cleaned of remaining residues of the upper adhesive layer 93 and then a new adhesive plate 91 can be inserted again.

In the event that an additional adhesive effect by the adhesive plates 91 is not required or is not desired, the adhesive plates 91 can also be omitted. Then the foot plate 81 lies on its foot studs 88 and on the annular ring beads 95 which surround the recesses 89 on the outside and which have at least approximately the same height as the foot studs 88.

In the guide body 21, the grip hole 32 is arranged in the full-length uppermost longitudinal section 31. The part of this length section 31 located between the grip hole 32 and the apex 96 of the guide body 21 (FIG. 1) serves as a grip strip 97 of the guide body 21. The guide body 21 can then be gripped and transported comfortably by hand. Insofar as the guide body 21 is combined with a holding device in the form of a base plate or a foot plate, which have relatively small dimensions and a relatively low weight, even the entire guide device can be gripped and implemented by means of the handle 97. So that due to the grip hole 32 and the grip 97 not the If there is a danger that a vehicle traveling over it, with parts protruding downward on its underside, will get caught on the handle bar, it is expedient to separate the handle bar 97 through a continuous slot 98 in the middle. Then the two separate sections of the handle 97 can each move to the side and immediately release a vehicle part rubbing against it. Since both sections of the grip strip 97 are gripped simultaneously when the guide body 21 is carried, the slot 88 does not impair the function as a support strip.

The guide devices 100 shown in FIG. 17 each have a hood-shaped guide body 101 and a foot sill 102. These two parts can be joined together by means of a coupling device 103 to form the guide device 100 and, if necessary, can also be separated from one another again.

The guide body 101 is designed in the same way as the guide body 21. Unless the details of the guide body 101 are explained separately below, the explanation of the guide body 21 applies at least analogously. In this case, the reference numerals of part of the details of the guide body 101 are to be evaluated increased by the number 80 compared to that of the guide body 21. The grip hole 109 is arranged in the upper solid length section 108. The wall areas 106 and 107 are each interrupted by a recess 111.

The foot 112 adjoins the lower end of the wall regions 104 and 105 of the broad sides of the base body 101. On its two broad sides in the area of its lower edge, the outwardly projecting retaining ribs are formed, through which the foot receives its L-shaped cross section on the long sides. Two transverse grooves 113 are formed on the upper side of the threshold 102 (FIGS. 18 and 19), whose cross section is matched to the cross section of the foot 112. Between the two grooves 113 there is a central part 114 of the foot sill 102, which has approximately the same height as the other parts of the top of the foot sill 102. This middle part 114 thus forms a type of guide rib between the two grooves 113, which it delimits from one another. The inner surfaces of the foot 112 bear against the side walls of the middle part 114 facing away from one another when it is inserted into the grooves 113. This results in an additional holding effect, which prevents the guide body 101 from being torn out of the grooves 113 in the event of a force acting in the longitudinal direction of the foot sill 102.

In the transverse direction, the guide body 101 is held on the foot sill 102 in particular by virtue of the fact that the portions of the foot 112 acting as parts of the coupling device 103 and the retaining ribs attached to them, on the one hand, and the grooves 113 and the central part 114 are closely tolerated with regard to their dimensions. An additional securing device is provided by a retaining lug 115, which is arranged on the middle part 114 at the location (FIGS. 18 and 19) at which the narrow side of the foot 112 which is at the front during the push-on movement is when the guide body 101 is open the threshold 102 is pushed on. The ramp-like nose bridge of the holding nose 115 is located on that side of the holding nose 115 which is opposite to the sliding movement of the guide body 101.

As can be seen in particular from FIGS. 18 and 19, the foot sill 102 has an at least approximately cuboid base 116. It is a molded plastic part and is generally made from recycled plastic. The length of the base body 116 is at least 1 m. Its height is between 70 and 100 mm and is preferably 90 mm. Its width is between 200 and 260 mm and is preferably 117 on the underside 230 mm. The width at the top 118 is preferably 190 mm. This results in an angle of inclination for the two side walls 119 and 121 with respect to the vertical of at least approximately 12.5 °. As can be seen from FIG. 18, the two end faces 122 and 123 are at least approximately perpendicular. As can be seen in particular from FIG. 19, these two end faces are curved in the shape of a circular arc, specifically the end face 122 located on the left in FIG. 19 and convexly curved and the end face 123 located on the right in FIG. 19 is concave. The radius of curvature of both end faces is at least approximately the same, so that they fit closely together.

The base bodies 116 are equipped with a coupling device 124, by means of which each foot sill 102 can be positively coupled in its longitudinal direction with an adjacent longitudinal sill and can be separated from it again.

The parts of the coupling device 124 are divided on a foot sill 102 into two groups, of which the one parts group 124.1 is arranged at the one end region with the convexly curved end face 122 and of which the second parts group 124.2 is arranged in the end region of the base body 116 with the concavely curved end face 123 is arranged (FIGS. 19 and 21 to 24).

Part group 124.2 includes a vertically upward coupling element 125 which is arranged at the end of a holding bracket 126. The bracket 126 is designed as a bar section, one end portion of which is angled at right angles to form the coupling element 125. At the opposite end of the bracket 126, the bar section is angled twice to form a hook-shaped end. The part of the hat clip 126 protruding from the base body 116 lies only slightly above the underside 117 of the base body 116 Coupling member 125 facing away from the length section of the bracket 126 is slightly offset compared to the length section adjoining the coupling member 125, so that the together with the adjoining hook-shaped end is located fully in the tear-open area of the base body 116 and is thus molded into the base body during its manufacture.

The coupling element 125 should lie as far as possible in the center of curvature of the concave curved end face 123. In addition, if possible, the coupling element should not, however, lie outside the envelope of the base body 116, that is to say it should not protrude beyond the end of the base body 116 in the axial direction.

Part group 124.1 includes a vertically upward-facing recess 127 on the underside 117 of the base body 116. This also includes a groove 128 on the underside 117. Like the coupling element 125, the recess 127 has a rectangular plan area, which is all the more so compared to the plan area of the coupling element it is much larger that a mutual rotary movement about the vertical axis by up to 1 ° is possible between the two parts. The recess 127 is at least approximately the same distance from the convexly curved end face 122 as the coupling element 125 from the concavely curved end face 123.

The groove 128 is matched to the shape of the bracket 126 so that the bracket 126 has full space in it. The plan area of the groove 128 is so much larger than the plan area of the bracket 126 that a mutual pivoting movement about the axis of the coupling member 125 by up to 1 ° is possible between these two parts.

Two perpendicular through holes 129 are formed in the base body 116 in its plane of symmetry. A cylindrical recess 131 is formed in each case at the upper end of the through holes 129. If necessary, ground screws in the form of cap screws can be inserted into the through holes 129 and screwed into holes in the carriageway, the head of the screw resting on the axial end face of the recess 131. Such an additional fastening of the foot sleepers 102 is expediently used when the entire guide device is to remain in place over a longer period of time and one also wants to prevent the foot sleepers from slipping even over short distances during this longer period of time.

As can be seen from FIG. 21, the base body 116 is provided on its underside with a larger number of recesses 132 predominantly with a rectangular plan area, so that the total weight of the foot sill 102 remains within a certain limit which, depending on the material used for the base body 116, is exceeded could be if the base body 116 were made solid with the given dimensions.

At the lower edge of the side walls 119 and 121, two recesses 133 are formed, which serve as grip holes when the threshold 102 rests evenly on the floor. Then you can reach under the edge with both hands from both sides and raise the threshold 102.

The guide devices 200 shown in FIG. 26 each have a hood-shaped guide body 201 and a foot sill 202. These two parts can be joined together by means of a coupling device 203 to form the guide device 200 and, if necessary, can also be separated from one another again.

The guide body 201 is designed in the same way as the guide body 101, to the explanation of which reference is made, the reference numerals of the guide body 201 being to be valued by 100 as compared to that of the guide body 101. The same applies to the details of the foot sill 202 interacting with the guide device 201.

As can be seen in particular from FIGS. 27 and 28, the foot sill 202 has an approximately cuboid or at least prismatic base body 216. It is a molded plastic part and is generally made from recycled plastic. The length of the base body 216 is at least 1 m. Its height is between 70 and 100 mm and is preferably 80 mm. Its width is between 200 and 260 mm and is preferably 240 mm on the underside 217. The width at the top 218 is significantly smaller and is preferably 130 mm.

The two side walls 219 and 221 running in the longitudinal direction have a plurality of wall sections with different shapes and different courses. The underside 217 is adjoined by an at least approximately perpendicular wall section 22 or 223, the height of which is between 15 and 25 mm and is preferably 20 mm. A transition region 224 or 225 adjoins this wall section 222 and 223, which is convexly curved in cross section. Its radius of curvature is at least approximately 20 mm. A transition region 226 or 227, which is convexly curved in cross section, also adjoins the top side 218. Its radius of curvature is also at least approximately 20 mm. Between the two transition areas 224 and 226 or 225 and 227 on one side there is a large wall section 228 or 229, which is concavely curved in cross section. Due to the given dimensions of the other parts of the cross-sectional shape of the foot sill 202, its radius of curvature is at least approximately 78 mm to ensure a constant transition from one surface or wall section to the next. This concavely curved wall section 228 or 229 forms, together with the transition area 224 or 225 adjacent at its lower end, a kind of footbed for a vehicle wheel that rolls obliquely towards the foot sill 202. This is especially true when the approach angle is very small. Then the vehicle wheel runs onto this footbed without difficulty. If the vehicle wheel continues to roll in this ascent angle, the concave wall section 228 or 229 and the transition region 226 or 227 adjoining it at the top act as a kind of ramp that allows the vehicle wheel to roll over the foot sill 202 without any major bumps.

As can be seen from FIG. 27, the two end faces 232 and 233 are at least approximately perpendicular. As can be seen in particular from FIG. 28, these two end faces are curved in the shape of a circular arc, namely the end face 232 on the left in FIG. 28 and convexly curved, and the end face 233 on the right in FIG. 28 is curved concavely. The radius of curvature of both end faces is at least approximately the same, so that they fit closely together.

The base bodies 216 are equipped with a coupling device 234, by means of which each foot sill 202 can be positively coupled in its longitudinal direction to an adjacent longitudinal sill and can be separated from it again.

The parts of the coupling device 234 are divided on a foot sill 202 into two groups, of which the one part group 234.1 is arranged at the one end region with the convexly curved end face 232 and of which the second part group 234.2 is arranged in the end region of the base body 216 with the concavely curved end face 233 is arranged (Fig. 28).

In the following, a modification of the guide device 201 is explained with reference to FIGS. 30 ... 32, which only affects its threshold. Insofar as the details of the threshold 302 are not explained separately below, the explanations for the threshold 202 according to FIGS. 26 to 29 apply, the reference symbols of the threshold 302 being increased by the number 100 compared to those of the threshold 202.

If the outer shape of the foot sill 302 is otherwise the same as that of the foot sill 202, for example in the region of the end faces 332 and 333, the base body 316 of the foot sill 302 has a plurality of foot knobs 335 on its underside 317. As can be seen from FIGS. 30 and 31, these foot knobs 335 are arranged in pairs in the region of the end sections of the base body 316, namely symmetrically to the longitudinal center line of the base body 316. A single foot knob 335 is arranged in the middle of the base body 316. There, however, the foot knobs can also be arranged in pairs symmetrically to the longitudinal center line of the base body 316. In addition, further foot knobs can be arranged, for example in the now knob-free surface areas on the underside.

The foot knobs 335 protrude approximately 3 mm downward over the underside 317 of the base body 316, so that the foot sill 302 generally only rests on the foot knobs 335 when they are used, at least on paved roads and squares.

In contrast to the adhesive sheets 91 in the relatively low corner areas of the foot plate 81 (FIGS. 15 and 16), the foot knobs 335 are formed by a circular-cylindrical insert 336, which is also arranged in a circular-cylindrical recess 337 on the underside 317 of the base body 316. The height of the insert 336 is at least approximately 30 mm. Its diameter is also at least approximately 30 mm. The height of the insert 336 exceeds the depth of the recess 337 by an excess of at least approximately 3 mm, by which the foot knobs 335 then protrude downward from the underside 317.

The easiest way to hold the inserts 336 in the recesses 337 is that the inserts 336 are made at least in individual areas of their circumference with a slight oversize of the radius compared to the radius of the recesses 337. In addition, however, the inserts can also be held in the recesses 337 by means of an adhesive, it being expedient if the adhesive application is only applied between the end faces of the inserts 336 and the bottom of the recesses 337, because there is a replacement of an insert that becomes necessary remaining adhesive residues can be removed more easily or can also be accepted rather than on the peripheral surfaces of the inserts 336 and the recesses 337.

The foot knobs 335 serve primarily to increase the slip resistance of the foot sill 302 or, in other words, to increase the resistance to displacement of the foot sill 302 when lateral displacement forces occur. In addition, the stability of the guidance device is also improved because its ground contact is concentrated in a few areas. In addition to the fact that by concentrating the weight of the entire guide device on the contact surfaces 338 of the foot knobs 335, the area load between the contact surface 338 and the floor at the place of use of the guide device is greatly increased, the slip resistance is also further increased by the foot knobs 335, ie the simplest are the entire inserts 336, made of a material of lower hardness than the material of the base body 336. Both a material can be considered for this is compacted and solidified from a granular base material with or without an additional binder by a pressing process. The Shore hardness of this material is expediently between 60 and 65. Since with such a material the granular base structure of the starting material results in the formation of a sandpaper-like surface, the contact surface 338 of the foot knobs 335 is given a surface structure which is very similar to that of asphalt road surfaces or concrete or related materials. As a result, a certain form fit is generated in addition to the force fit due to the normal frictional forces. The same effect is achieved if the inserts 335 are made from a homogeneous rubber or plastic which on the one hand has great tear strength and on the other hand has only a low level of dimensional stability, which is therefore very flexible and at the same time very tough. As a result of the low dimensional stability, even with a smooth contact surface 338, the material is able to press into the unevenness of the road surfaces, so that an additional positive connection is also achieved here. The high tensile strength of the material prevents the surface areas of the foot knobs 335 which have penetrated elastically into the unevenness of the road surface from being sheared off when lateral forces, ie shear forces, occur on them.
