Retractable barrier bollard

The innovation relates to a barrier bollard with an outer round pipe inserted into the ground, into which the barrier bollard is is retractable.

Bollards are part of everyday life: · large Variety in use, usually to provide a barrier for vehicles. Because such a barrier is often only At times it is desired, it is known to design a retractable barrier bollard by placing the actual barrier bollard in an outer tube and the outer tube itself is buried in the ground.

In order to be able to use such bollards in public transport ¹ as a barrier beacon, they must be provided with a red and white striped color code.

Retractable bollards are already known, which consist of a round outer tube and a round bollard or bollard. consist of a square outer tube and a square bollard. The inside dimensions of the in the ground The outer pipe used are designed in such a way that the barrier bollards, which basically have the same cross-section is displaceable with relatively little play in the outer tube.

In such known barrier bollards, which are either as a round bollard in an outer round tube or as a rectangular polisher in an outer square tube are displaceable, is the distance between the outer surfaces of the bollard and the Make the inner wall of the outer tube as small as possible so that the bollard is well guided in the outer tube and as firmly as possible is held against lateral tilting. If such a well-known bollard with the ones required in public transport Color codes, these color codes are damaged very quickly when the barrier polisher is extended and retracted and rubbed off.

Further difficulties also arise from the fact that such known barrier bollards are lowered in winter freeze easily and then difficult or impossible to pull out. With bollards that are rarely used and are therefore sunk over a relatively long period of time, it can also happen that these little play between the outer pipe and the barrier bollard despite the presence of protective coatings over time rust and then hardly pull out jind.

The innovation is therefore based on the task of creating a retractable To create barrier bollards in which, due to the structural design, the damage to the Parbknung am Barrier bollards during lowering and pulling out

In addition, it is to be avoided as far as possible if the barrier bollard is handled correctly. Furthermore, the Äbspeirpoller should uuch offer a possibility that in the space «wipe the Barrier bollard and the outer pipe through the upper receiving opening penetrated soil and moisture not to one Jamming or rusting and freezing of the barrier polisher sunk in the outer tube.

This object is renewal according achieved in that the traffic control consists of a square tube, that the square tube has a diagonal diameter of approximately the inner diameter of the outer round tube and in that the square tube is supporting the outer round tube by einen'oder multiple guide inserts _overall%.

Achieved by this configuration of the retractable barrier polishing it is advantageous that between the square surfaces of the barrier bollard and the inner wall of the outer round pipe a segment-shaped free space is created so that on the one hand, soil that has penetrated downward falls through karoi j and on the other hand the square surfaces of the barrier bollard

no longer rest on the inner wall of the outer round tube and

j when pulling out or lowering the barrier bollard, ¹ ·. on the outside

rub the pipe.

By designing the relatively large free Space between the square tube of the barrier bollard and the outer round tube, there is also no risk of penetration the bollard in the outer round pipe freezes from moisture or the square tube can rust over a large area in the outer round tube and can therefore no longer be pulled out.

According to a further embodiment of the innovation, it is provided that the guide insert comprising a receiving opening one inserted or welded into the outer round tube

3R7G-1138

There is a disc, the receiving opening with guide angles running at a small distance from the edges of the square tube is provided and in the area of the square surfaces in a greater distance to these runs.

Such a designed retractable, square bollard is when lowering and pulling out with the help of the guide insert safely guided, the latter only on the edges of the square Barrier bollard rests and slides along this as well as sufficient free space between the square surface and the inside edge of the receiving opening in the guide insert offers, so that damage to the surface of the storage bollard or the coating applied to it is avoided.

According to a further embodiment of the innovation, it is provided that the guide angle in the apex area with an approximately circular recess are provided in which a round rod or rod welded onto the outer edge of the square tube. Bead is performed. This configuration makes it possible to achieve that the square bollard with its longitudinal edges can be guided with only a very small distance from the inner surface of the outer round tube, so that no larger Surfaces that are directly opposite each other that freeze or rust prevent the bollard from being pulled out to make impossible.

In order to hold the barrier polisher securely in its position both in the retracted position and in the pulled-out position, is provided according to the innovation that on the inner jacket of the outer round tube over part of the length or over the entire length of the locking rails are arranged diametrically opposite one another and approximately parallel to the corresponding one The outer surface of the square tube runs, and that the locking rails are provided with locking scales are in which a bolt held on the square tube

For this locking mechanism there is another Design of the innovation provided that this comprises a rod running through the square tube, which at its lower End of the bolt carries that the RiegejL with one on this attacking spring is retained in the locking position and that the bolt with the rod against the force of the spring the locking position is pivotable.

With a locking mechanism designed in this way the shut-off polisher can be locked firmly in the outer round tube both in the retracted and in the pulled-out state taking care that it does not look out of the lock due to any jolts solves.

According to a further embodiment of the innovation, it is also provided that that the rod ends under a spherical cap that closes the square tube at the top and through an opening in the Calotte is operable. In the area of the opening, the dome is provided with a recess into which a cover plate Can be used flush with the surface. This cover plate is with the help of a through the sleeve in the interior of the square tube extending pin supported horizontally pivotable and vertically displaceable.

This cover ensures in an advantageous manner that the locking mechanism from coarse through the access opening is protected from dirt.

According to a further embodiment of the innovation, it is also provided that that the square surface of the barrier is provided with a light-reflecting coating, whereby this coating can consist of a reflective film.

The spherical cap 13 has a depression in the area of the opening 15 16 provided, in which a cover plate 17 is flush with the surface can be used. This cover plate is made with the help of a pin 19 extending through a sleeve 18 horizontally mounted pivotable and vertically displaceable. The pin 19 is provided on the underside with a stop washer 20, so that the cover plate cannot be pulled out of the dome and is therefore not lost.

The locking mechanism 3 cooperates with locking rails 21 which are welded onto the inner jacket of the outer round tube over part of the length or over the entire length and which are diametrically opposed to each other and run approximately parallel to the outer surfaces of the four-car.tube. These locking rails 21 are provided with locking slots 22 in which the pivotable bolt 9 engages. The pretensioning of the spring 11 ensures that the bolt 9 assumes the locking position shown in FIG. 1 in the rest position. Before lowering or pulling out the barrier bollard, the bolt 9 is ^{pivoted against the force of the spring 11 by turning the rod y} + into the interior of the square barrier bollard so that the barrier polisher can be moved upwards or downwards in this position within the outer round tube. As soon as the barrier bollard with the bolt 9 disengaged from your slot 22 is shifted slightly up or down, the locking mechanism can be released so that the bolt 9 rests on the inner surface of the locking rail 21 and on this when pulling out or sinking of the barrier bollard slides along until it comes into the plane of the upper or lower locking slot 22 and then is pivoted back into the locking slot 22 by the force of the spring 11.

The outer round tube 2 is completely replaces them a ^ in the ErdroLch \>, whereby preferably care is taken through a gravel pack below a closure plate 23 at the lower end of the Ausscinrundrohreü 2 and through an opening provided in the end plate 23 opening 24 that penetrates into the outer round tube liquid can seep downwards.

The upper end of the outer round tube 2 is disk-shaped Guide insert 6 closed. This guide insert 6 is preferably welded onto the upper end and has a diameter approximately corresponding to the dome 13. It is thereby achieved that the spherical cap 13 is in the lowered state of the barrier bollard completely covers the guide insert 6, which means that the receiving opening 7 in the guide insert 6 for the Square tube of the barrier bollard 1 is closed. The shape of the receiving opening 7 is based on the sectional view according to FIG. 2 in detail. As can be seen from this illustration, one is basically the square shape of the Barrier bollard 1 adapted receiving opening 7 in ά · 3η disk-shaped Guide insert 6 incised, but the inner edges of the receiving opening, which are the square surfaces opposite, run at a sufficiently large distance from them, so that when lowering and pulling out the barrier bollard 1 these square surfaces do not come into contact with the inner edges of the receiving opening. In the field of Guide brackets 8 are arranged along the longitudinal edges of the barrier bollard 1, which lie with their guide surface at a short distance from the edge areas of the square tube and when moving of the barrier bollard this with a relatively low Lead game. The guide angles 8 are provided in the apex area with an approximately circular recess 24 in which a round rod or bead 25 welded onto the outer edge of the square tube is guided. By providing one such a round rod or bead 25 on the outer edge of the square tube can ensure that the square

pipe of the barrier bollard practically only along a line in the The edge area rest on the inner surface of the outer round tube can, with which a freezing or plague rusting, even if it is unavoidable, the pulling out of the barrier bollard not makes impossible.

Below the guide insert 6, in the interior of the The outer round tube has a free area in the shape of a segment of a circle between the inner jacket of the outer round pipe and the four-sided surface of the barrier policeman. This free area ensures that even through the slot in the guide insert between the inside edge of the receiving opening and the square tube of the barrier bollard penetrating soil freely fall down can and cannot be between the bollard and jammed in the inner jacket of the outer round pipe.

Due to the precise guidance when sinking and pulling out of the barrier bollard through the guide bracket 8, it is also ensured that the greater distance between the locking rails 21 and the outer surface of the Vicsrkant tube remains essentially the same and the locking rails also always essentially parallel to the surface of the Square tube run because the barrier bollard within the Aussinrundr ohr it "is not rotatable.

To use the barrier bollard in public transport, you must this must be marked as a barrier beacon in the form of a striped color marking. This color marking preferably exists from a white-red coating of the square surface of the barrier bollard, e.g. in the form of fjirbe or a glued-on reflective film, by the distance between the inner edge of the receiving opening 7 and the square surface of the Barrier bollard in the area of the guide insert 6, and also through the free circular segment-shaped interior between the Inner jacket of the outer round tube and the square surface
