Description

field of technology

[0001] The technical solution concerns the area of ​​impact protection devices, specifically the adjustment column of the modular impact protection system. The current state of the art

[0002] In large industrial areas, as well as in outdoor and indoor parking lots, traffic areas must be demarcated to prevent collisions between vehicles and people, and to prevent damage to facilities or buildings. Impact protection devices, such as bollards, are used for this purpose. Bogies are primarily made of metal or plastic with an internal cavity or solid material, and are anchored in the ground or a base. When a vehicle collides with such a bollard, it causes mechanical damage to both the bollard and the vehicle. This results in significant damage, necessitating the replacement of the bollard and the repair of the base or the building assembly due to the impact against the heavy metal bollard.Another disadvantage is that these protective pillars are coated to increase their visibility, but this coating also serves to prevent surface oxidation. If a vehicle collides with a protective pillar coated with this material, the coating flakes off in places, causing the pillar to corrode over time and eventually requiring replacement.

[0003] Another well-known type of impact protection consists of columns made of extruded polymer rods with a metal core. The protective column is equipped with a cap to prevent liquid from penetrating the metal core. A similar solution involves protective columns made of a rubber-coated steel core, also fitted with a cap. While this solution avoids the potential for corrosion, upon impact the entire protective column structure breaks away from its base, necessitating replacement of the entire column or repair of the base and anchoring elements.

[0004] These disadvantages were partially addressed by using the protective column described in document FR 2953534, which comprises an aluminum core sealed in the ground. A plate with a welded axial fixing screw is attached to the lower part of the core. A polyurethane cap is mounted on the fixing screw, and a metal impact protection bar is mounted on the polyurethane cap. The disadvantage of this solution is that it deforms excessively upon impact and therefore offers no real impact protection. Another drawback is that the protective column exhibits permanent deformation after even a minor impact, without elastically returning to its original position.

[0005] Another type of protective column is described in document EP 2 685 002, which describes a protective column formed by a barrier and anchoring means for securing the protective column to the base. The protective column consists of an inner cavity and a casing, with a threaded rod and lock nut located in the inner cavity. The lock nut engages with the upper bearing surface of the protective column. The other end of the threaded rod is adapted for screwing into the anchoring means. This solution allows for immediate locking of the protective column in the anchoring means without the need for additional fasteners such as resins. However, the disadvantage remains a high degree of deformation in the event of an impact.

[0006] This disadvantage was partially overcome by the development of a modular impact protection system according to document EP 3 175 044, which describes a protective column formed by an adjustable column. The column consists of an outer body with an inner cavity and a lower section containing a continuous recess through which a screw passes. The protective column is further formed by anchoring means for the detachable attachment of the outer body to the base or to another adjustable column. The protective column comprises at least two adjustable columns, each additionally equipped with a connecting element for connection to the outer body. This connecting element is fitted with a screw located in the recess and passing through the lower section of the outer body of another adjustable column. The protective column is made of plastic, and the screw is made of steel.This solution allows for the modular assembly of columns of varying heights, the easy replacement of a single damaged adjustment column, and simplifies single-piece production. However, a disadvantage is the relatively low impact resistance, which can lead to breakage of the adjustment columns at the connection point, i.e., at the weakest point of the plastic part, the screw thread.

[0007] The task of the technical solution is therefore to create such a modular impact protection system or such an adjustment column that is impact-resistant without interrupting the connection of the adjustment columns or the connecting module. Nature of the technical solution

[0008] Technical solution for an adjustment column of a modular impact protection system, comprising a means consisting of a cylindrical enclosure formed at one end of the adjustment column, having an external thread and forming a single integral unit with the body of the adjustment column, wherein in the middle region of the cylindrical enclosure there is a bore opening into the inner cavity and simultaneously is open at the end of the cylindrical enclosure where there is a hexagonal recess into which a nut with the overlap is inserted, and the connecting element further comprises a screw which can be screwed into the nut, wherein the head of the screw rests on the bottom of the inner cavity and the end of the screw does not protrude beyond the opening of the bore including the nut.

[0009] In a favorable embodiment, the inner cavity at the other end of the adjustment column has an internal thread for receiving the external thread of the cylindrical housing of another adjustment column. Such an arrangement simplifies the assembly of the adjustment columns into a unit, whereby the cylindrical housing of one adjustment column and the thread of another adjustment column form a sufficiently secure connection so that the operator can handle them when screwing the screw into the assembly.

[0010] In another cost-effective version, the adjustment column is made of a plastic-based material. This material is suitable for rapid production and readily available; adjustment columns manufactured in this way are sufficiently impact-resistant and can be easily replaced when worn.

[0011] The technical solution is further achieved by an arrangement of adjustable columns of a modular impact protection system, comprising two adjustable columns, each consisting of a casing, an inner cavity, and a connecting element for joining to another adjustable column. The essence of the technical solution lies in the fact that the adjustable columns are formed as described above, with a cylindrical insert having an external thread on the first adjustable column being screwed into the inner cavity having an internal thread. Such an arrangement provides high impact resistance without the adjustable column breaking at the point where the cylindrical insert of one adjustable column is inserted into the inner cavity of another.

[0012] The technical solution is further implemented by an assembly consisting of a base column and an adjustable column of a modular impact protection system. The base column comprises an outer casing and an inner cavity, and at least one adjustable column comprises a casing, an inner cavity, and a connecting element for joining it to the base column. The essence of the technical solution lies in the manufacturing of the adjustable columns as described above, with the cylindrical end of the adjustable column being screwed into the inner cavity of the base column. The other end of the base column is provided with an opening for receiving anchoring elements that connect the assembly to the base. This arrangement ensures a secure anchoring of the assembly to the base, which could be, for example, a concrete subfloor in industrial facilities or garages.Anchoring the base column using the anchoring devices prevents the entire modular impact protection system from breaking out in the event of a collision.

[0013] In a favorable embodiment, the inner cavity at the other end of the adjustment column has an internal thread to receive the external thread of the cylindrical housing of another adjustment column. Such an arrangement ensures a sufficiently tight connection between the cylindrical thread of the adjustment column and the base column, allowing the operator to screw the screw into the assembly.

[0014] The technical solution is further achieved through a modular impact protection system consisting of a base column with an outer casing and an inner cavity, and an adjustable column with a casing, an inner cavity, and a connecting element for joining it to the base column. The essence of the technical solution lies in the fact that the base column and adjustable column assembly is formed as described above, with the cylindrical housing of the adjustable column being screwed into the inner cavity of the base column, and the assembly also includes the cap mounted on the adjustable column. Such a modular impact protection system exhibits high impact resistance, is easy to design, and the individual components are straightforward to handle.

[0015] The advantages of the adjustable column of the modular impact protection system according to this technical solution are primarily that it is impact-resistant without interrupting the connection of the adjustable columns or the connecting module. Explanation of the drawings

Fig. a cross-sectional drawing through the base column with anchoring devices in a stretched state. Example of the implementation of the technical solution

[0017] The modular impact protection 2 is formed as an assembly consisting of a base column 5, two adjustable columns 1, 1', anchoring means 19 and a cap of the assembly. In other embodiments, a different number of adjustable columns 1, 1' can be used.

[0018] The base column 5 consists of a plastic-based material and is formed by an outer shell 16 of the base column 5 and an inner cavity 17 of the base column 5.

[0019] At the other end of the base column 5, a first adjustable column 1 is mounted, which is formed by an outer sheath 3, an inner cavity 4, and a connecting element. The adjustable column 1 consists of a plastic-based material based on high-density polyethylene, as described in the Fig. and the Fig. The connecting element is an integral unit of the adjusting column 1. It is formed at one end of the adjusting column 1 as a cylindrical receptacle 6 with external threads 9, 9', wherein a nut 8 with overlap is mounted in a hexagonal recess 7. The external thread 9 fits into the thread 15 in the inner cavity 17 of the base column 5. Subsequently, the assembly consisting of the base column 5 and the first adjusting column 1 is fastened by means of a screw 12', which is screwed into the nut 8 and wherein the head 13 of the screw 12 extends to the bottom 14 of the inner cavity 4 of the first adjusting column 1.

[0020] The other end of the adjusting column 1' is provided with a thread 15 into which the external thread 9 of the cylindrical housing 6' of the second adjusting column 1' fits, in order to establish a sufficiently stable connection before the screw 12 is screwed into the nut 8 of the second adjusting column 1'. The second adjusting column 1' is formed by an outer shell 3', an inner cavity 4', and a connecting element in the form of a cylindrical housing 6', which also forms an integral unit with the adjusting column 1'. The cylindrical housing 6' of the second adjusting column 1' is identical to the cylindrical housing 6' of the first adjusting column 1, i.e., it has an external thread 9', with a nut 8 with overlap mounted in the center of the cylindrical housing 6'. The external thread 9' fits into the thread 15 in the inner cavity 4 of the first adjusting column 1.The assembly consisting of the first adjustment column 1 and the second adjustment column 1' is then attached to the body of the second adjustment column 1' using the external thread.

[0021] The second adjustment column 1' is also provided with a thread at its other end, into which the cap of the modular impact protection 2 fits. In another example of the implementation, not shown, the second adjustment column 1' is not provided with a thread at its other end, and the cap of the modular impact protection 2 is simply force-fitted onto this other end of the adjustment column 1'.

Furthermore, the adjustable column of the modular impact protection system can be used to secure parking lots, industrial halls, workshops, corridors for goods transport, or pedestrian walkways.

[0023] The adjustable column (1) of the modular impact protection system (2) comprises a casing (3), an inner cavity (4), and a connecting element for connection to a base column (5) or another adjustable column (1').
