Traffic sign bearer

The invention relates to a traffic sign carrier with a carrier tube for the traffic sign (s), with a fixed inside Ground anchored receptacle and with an intermediate sleeve, which at one end with the receptacle and at the other end with the Support tube is plugged together and connected.

In general, traffic signs are attached to the upper end of a support tube that is attached to the installation site in the Soil at the side of the roadway, at intersections, sidewalks, etc. is concreted in. The advantage of this known traffic sign carrier lies in the fact that the traffic signs are kept largely free of vibrations even in strong winds In addition, theft or willful removal of the sign carrier is not possible. However, it is disadvantageous that a kinked support tube damaged by starting or in any other way is only replaced as a result can be that the concrete foundation is removed with. This is time consuming and costly.

It has therefore already been proposed that the carrier tube of traffic signs into a separate ground socket, which is firmly anchored in the ground, and there by means of locking devices to keep (DE-OS 26 44 333). The disadvantage of this design, which has not found its way into practice, is that one relatively complicated locking device is necessary, which can also be solved at any time, so that the traffic signs cannot be set up to prevent theft.

In another design (DE-OS 24 10 627) it is provided to insert an intermediate sleeve into the ground sleeve, into which then in turn, a carrier tube is inserted, which is adjustable in height with respect to the intermediate sleeve and can be screwed tight at a desired height. This traffic sign is also with its carrier easily removable, in addition, the connection between the intermediate sleeve and the support tube leads to a certain Game, which has the consequence that even after the screwing, a wobbling of the at a certain height above the connection point seated traffic sign cannot be ruled out. The known design is also relatively complex and has a crucial The disadvantage is that the carrier tube is completely in the event of a strong impact, e.g. as a result of a vehicle crashing into it is kinked and a risk of injury for passers-by and also for the driver of the vehicle causing the damage caused because the kinked traffic sign carrier breaks off and can swirl freely through the air and e.g. can be thrown through the windshield of the vehicle causing the damage.

The invention is based on the object of a traffic sign carrier to create, which is easily replaceable in the event of damage, but in which there is largely the risk of complete demolition is avoided and which can be produced and set up in a stable manner simply and with little effort.

The invention consists in that the intermediate sleeve is frictionally engaged is plugged together with the support tube and the receptacle in such a way that an axial distance remains between the two, that it is formed from two tubes lying one inside the other, of which the outer tube is in the region of the axial distance is designed as a corrugated pipe and that the corrugated pipe and inner pipe have the same bending resistance as the support pipe. This configuration ensures that a predetermined breaking point in the area of the greatest bending moment between the The lower edge of the support tube and the upper edge of the BodeB mount are created, at which the traffic sign carrier is bent or kinked under heavy load. Even so, the dangerous demolition becomes of the support tube avoided because the outer tube of the intermediate sleeve, which is in the area between the lower edge of the support tube and the upper edge of the ground sleeve is designed as a corrugated tube, in this case expands and a kind of lanyard function developed. This prevents a kinked traffic sign carrier from tearing off completely, so that the risk of personal injury is reduced or avoided. In that the wall thickness of the intermediate piece is so designed is that the deformation resistance of the corrugated pipe together with the deformation resistance of the inner pipe approximately the bending resistance of the carrier tube corresponds and the intermediate piece with frictional engagement both in the carrier tube and in the Recording is inserted, there is a firm, reliable and not wobbling 'attachment of the traffic sign carrier. Of the Frictional engagement can be produced with such a force that deliberate removal or rotation of the traffic sign not possible. In the event of slight damage, the traffic sign carrier can easily be straightened up again without the damage to the inner pipe being visible, since the corrugated pipe then assumes its original position again.

In an advantageous embodiment of the invention, the Carrying the tube, the intermediate sleeve and the pufnahire in the bottom of round tubes

formed and it corresponds to the inner diameter of the support tube and the inner diameter of the receptacle >. the outer diameter of the intermediate sleeve in two plug-in areas, between which the corrugated pipe area lies. The advantage of this embodiment is that the intermediate sleeve is the same in the two insertion areas Can have diameter and therefore not with gradations for adaptation to different dimensions of the support tube and the recording needs to be provided. When inserting the intermediate sleeve there is therefore no need for a specific orientation be respected. The use of round tubes has the advantage that the carrier tube and thus also the traffic sign with already anchored recording is still oriented in any direction. can be.

In an expedient development of the invention, the inner tube and the corrugated tube, which together form the intermediate sleeve, are axial secured against each other, preferably by welding. This ensures that when the intermediate sleeve is inserted, the Do not move the two pipes against each other. When assembling the intermediate sleeve, it is inserted into the Ground sleeve pressed in to create the frictional connection. For this purpose, it is beneficial if the inner tube is at least as long is that it ends at the same level as the outer tube. The forces during impact are then essentially of the Inner tube, which has a higher axial section modulus than the outer tube, was added, so that the intermediate sleeve can be knocked in is easily possible.

To secure the support tube opposite the .Aufnahme i ⁿ ~ ^To circumferential direction, it is advantageous if a security against rotation of the intermediate sleeve relative to the support tube or receptacle is provided. This security against rotation can be produced, for example, using blind rivets. In this context, there is a further advantage that the inner pipe and the corrugated pipe are secured against each other axially, since then the aligned drilling holes to be provided both in the inner pipe and in the corrugated pipe.

Do not move the stanchions to accommodate the blind rivets against each other can.

In order to establish a reliable frictional connection between the plug-in areas of the intermediate sleeve and the support tube or the receptacle different solutions are possible. Because of the tolerances of the diameter that occur in practice during manufacture the ends of the spacers are slightly tapered. The necessary frictional engagement or play compensation is through Conical sleeves or partial bulges or annular bulges achieved, whereby a non-wobbling and firm connection of the support tube arises.

In the following the invention is illustrated in the drawing Embodiment further explained and described. Show it:

1 shows a traffic sign carrier according to the invention with a partial longitudinal section in the floor area,

Fig. 2 shows an embodiment of an intermediate sleeve,

3 shows a longitudinal section through an intermediate sleeve which is fastened with conical sleeves and annular beads,

In the drawing, 1 is on the whole a traffic sign carrier according to the invention shown, in which a provided with a traffic sign 2 support tube 3 via an intermediate sleeve 4 with a receptacle 6 firmly anchored in the floor 5 is connected. The receptacle 6 consists of a stable round tube held in the ground or solid piece and protrudes upwards somewhat from the floor 5, in which it is concreted out. The intermediate sleeve 4 has two tubes 7 and 8 lying one inside the other, of which the inner tube 7 has a somewhat lower resistance to deformation than the support tube 3 owns. The outer tube 8 is in the area a, which after assembly between the lower edge 10 of the support tube 3 and

-8th-

- - ^: - ■ ■ - ^: 33U701

the upper edge 9 of the bottom receptacle 6 comes to rest when Corrugated tube 11 formed and provided with radially outwardly protruding and circumferential corrugated ribs. The inner tube 7 and the outer tube 8 are of the same length and are secured against one another in an axially immovable manner by welding.

As can be seen, the intermediate sleeve 4 is inserted with an insertion area 12 into the receptacle 6 and with an insertion area 13 in the support tube 3 . This area represents a kind of predetermined breaking point because this is where the greatest bending moment occurs when the support tube 3 is loaded. The outer diameter d- of the intermediate sleeve 4, which is the same for the two plug-in areas 12 and 13, corresponds to the same inner diameter d _{2 of} the receptacle 6 and d _{3 of} the support tube 3. The thickness of the inner tube 7 and the corrugated tube Π are matched to one another, that they correspond to the rigidity of the support tube 3.

For assembly, after setting in concrete or after anchoring the concrete block in which the receptacle 6 is held, the Intermediate piece 4 pushed into the receptacle 6 with the insertion area 12, if necessary with the aid of a striking tool, with which the sleeve 4 is hit from above. The forces are essentially generated by the inner tube 7 added, which leads to no deformation of the intermediate sleeve. This happens until the lower one shown in FIG. 1 Area of the corrugated pipe 11 is seated on the upper edge 9 of the receptacle 6. Then the carrier tube 3 can with the traffic sign placed over the insertion area 13 of the intermediate sleeve 4 This is possible until the lower edge 10 of the support tube 3 is seated on the upper region of the corrugated tube 11. When inserting, a reliable frictional engagement is created in both insertion areas 13 and 13, through which in part the Weight of the support tube 3 and the traffic sign 2

is taken. Furthermore \ τΐχκίοη , iIhm, -nu'h »lit · Kr II ι ipjn-n \ Uit -trägerx'ohr 3, because it sits there. To secure the support tube 3 against the receptacle 6, blind rivets 14 are provided at various points, which on the one hand secure the intermediate sleeve 4 in the plug-in area 13 relative to the support tube 3 and on the other hand in the plug-in area 12 relative to the receptacle 6, both axially, but especially in the circumferential direction. Deliberate removal or theft is prevented by this and also because of the frictional engagement that is generated.

If the shown traffic sign carrier is approached and takes place only slight damage, the area of the corrugated pipe 11 expands on the impact side by the corrugated ribs be widened. On the opposite side there is a corresponding compression, which is also where the Inner tube 7 deformed. In this case, the traffic sign bearer can can easily be straightened up again without the deformation of the inner tube being visible from the outside. When bending back, the corrugated pipe 11 stretches and takes its original shape again. It has been shown that the This does not impair the stability of the traffic sign carrier, but on the contrary increases it, since the inner tube 7 in the case described is given a higher rigidity during bending back by cold deformation than before the deformation. If the sign carrier is severely damaged, so the inner tube is in the area between the lower edge 10 of the support tube 3 and the upper edge 9 of the ground sleeve 6 existing predetermined breaking point kinked. The corrugated pipe 11 is developed in this case a kind of lanyard function and secures the traffic sign carrier against a complete demolition. That Support tube 3 and the receptacle 6 are usually not damaged in such a case, so that only the intermediate piece must be replaced and the traffic sign can still be used with the carrier tube. Here of course you have to the rivets 14 are removed and replaced with new ones. This replacement of the intermediate sleeve 4 is with little work and Time to accomplish.

On the basis of the exemplary embodiments of intermediate sleeves shown in FIGS. 2 to 4, some possibilities are shown below described, which exist to ensure a reliable frictional engagement between the intermediate sleeve and the support tube or the recording.

The intermediate sleeve shown in FIG. 2 shows the design according to the application according to FIG. 1.

3 shows a longitudinal section through an intermediate sleeve with a conical frictional engagement. As an example in the above Part of the frictional engagement in the area 13 is achieved by the slotted tapered clamping sleeve 15 and as an example in the lower part the frictional engagement in the area 12 by an annular bead 16 which is attached to the outer tube 8.

Fig. 4 shows an embodiment of the tapered sleeve used 15 fig.

Fig. 5 shows a modified embodiment of the subject matter of the invention insofar as here the ^{intermediate sleeve 4 'consisting of the two nested tubes 7' and 8 1} as a whole is slightly conical and its larger diameter D ₁ at the lower edge, the smaller diameter D2 on the other hand, at the upper edge. The diameters Ό _Λ and D are so

¹ 2 matched to each other that, for example, a cone with a slope of 1:30 results. The lower connection area 3a of the support tube 3, to which, as in FIG. 1, the traffic sign is attached, has a corresponding cone. The connection area 3a of the support tube 3 is pushed over the intermediate sleeve 4 from above in such a way that the intermediate sleeve 4 and the support tube 3 sit snugly one inside the other. The lower area of the intermediate sleeve 4 is pushed outside over the connection area 6a of the receptacle 6, the area 6a again having a 1:30 cone, the tip of which points upwards so that the intermediate ^{sleeve 4 1} sits firmly on this conical part 6a. In this embodiment, too, the outer tube 8 'has the corrugations 11 and it is

ML

just as in the embodiments of FIGS. 1 and 3 together formed with the inner tube in such a way that it has the same bending resistance as the support tube 3. The conical connection area 3a of the support tube 3 is provided with an external annular reinforcement in the form of a reinforcement sleeve 20. This reinforcement sleeve 20 is pushed over the support tube 3 from the outside, clamps on the lower conical area 3a and 3b is also there in a known manner either spot-welded or otherwise fixed and captive connected to the carrier tube 3. The inner tube 7 'of the intermediate sleeve 4 'is also provided with an inner reinforcement sleeve 21 in the area of the reinforcement sleeve 20, but this is somewhat higher than the reinforcement sleeve 20. The reinforcement sleeve 21 is also pushed into the inner tube from the inside and there in a known manner, for example by spot welding, firmly and captively to the inner tube 7 and thus to the intermediate sleeve 4 connected.

The construction of the traffic sign carrier of FIG. 5 is extremely simple. This is because only the intermediate sleeve 4 ¹ needs to be pushed onto the connection area 6a of the receptacle 6 from above. Due to the conical design, it sits firmly. The support tube 3 with the conical connection area 3a is then pushed ^{over the intermediate sleeve 4 1 from above.} The carrier tube 3 with the traffic sign is stuck due to the conical design. Securing, as in FIG. 1, by means of the rivets 14 is possible, but not absolutely necessary, since the result is a very good press fit with the selected weak cone. It has been shown that in this embodiment a relatively frequent deformation of the traffic sign carrier by kinking is possible before the corrugated pipe 11 or the outer pipe 8 ¹ or the inner pipe 7 'tears and has to be replaced. The exchange can be made in a very simple manner in that pulling devices are placed under the lower edge 20a of the support tube 3, which then enable the loosening either via a screwing process or also hydraulically. In a similar way, the intermediate sleeve 4 is released, in that at its lower edge 4a

a corresponding puller is attached, for example can be supported on the floor 5.
