Description

[0001] The present invention relates to a device for preventing entry into the road.

[0002] It is known that heavy concrete blocks are used to temporarily prevent entry to the road in public places on certain occasions when a large number of people gather, in which way it is avoided that trucks or other vehicles can enter the crowd.

[0003] The disadvantages of this approach are reflected in the fact that concrete blocks are very heavy, and placing these blocks requires the use of heavy equipment and a considerable amount of time. Another disadvantage is that these blocks cannot be quickly removed in emergency situations when access to a public place needs to be urgently provided.

[0004] Other temporary systems to prevent entry to the road mainly consist of the installation of obstacles, for example using barbed wire or other materials.

[0005] These safety measures are usually very cumbersome and also require a lot of time to reopen the road.

[0006] Also, from the document JP H06 71515 U, road barriers are known which include concrete elements that extend horizontally through holes equipped with detachable posts.

[0007] Furthermore, document GB 2 434 393 A shows a barrier system for restricting access to vehicles which consists of a support with an elongated hollow arm mounted thereon to enable linear reciprocating movement by means of a motor.

[0008] The purpose of the present invention is to provide a solution for at least one of the aforementioned and other disadvantages.

[0009] To this end, the invention relates to a device for preventing entry into the road as defined in Claim 1. Also, a set of such devices is defined by Claims 12 and 13.

[0010] The advantages of the invention are reflected in the fact that the profile can be easily and quickly extracted from the concrete block in order to block the entrance to the road. In order to enable the entrance to the road again, the profile is pulled in the other direction (toward the concrete block). This pulling out or pulling in can preferably be done by one person, manually, without additional help.

[0011] The device to prevent entering the road can be temporary or permanent. Concrete blocks can be moved by any means of transport.

[0012] The concrete block can be placed in advance while the entrance to the road is still open. When it is necessary to block the entrance to the road, it is only necessary to pull out the profile and place it over the entrance to the road.

[0013] The profile is supported by the concrete block both when pulling out and when pulling in the profile.

[0014] The profile is placed horizontally so that it can be pulled out in the longitudinal direction of 1 concrete block.

[0015] It is desirable that the profile can be pulled out via two roller bearings placed in the longitudinal direction of the concrete block.

[0016] According to a preferred embodiment of the device according to the invention, the profile can be drawn from both sides of the concrete block.

[0017] The profile can be pulled out through the concrete block from both the left and the right side. In this way, the concrete block can be placed both on the left and on the right side in relation to the entrance to the road. The free end of the profile can be pulled out of the concrete block for the maximum length L-I. L is the total length of the profile and 1 is the length of the concrete block in the direction of the profile.

[0018] It is desirable that the profile is pulled out to the maximum length when one end touches the concrete, so that the profile is always supported by two roller bearings.

[0019] The concrete block is made of reinforced concrete. In this way, the anti-traffic device is strengthened and prevents the concrete block from breaking or the profiles from loosening in the event of an impact.

[0020] The block of reinforced concrete has a casing in the form of a steel rod in which a profile that can be pulled out is placed. The concrete block should preferably have a flared base and may be narrower at the top.

[0021] According to a preferred embodiment of the device according to the invention, the profile is made of steel.

[0022] The steel is very strong and provides sufficient resistance in case of a possible impact with the profile. The concrete block must have sufficient mass to be able to provide resistance when hitting the profile.

[0023] In the device according to the invention, the profile is an I-profile that can be pulled out via roller bearings. Preferably, the middle arm of the I-profile is placed horizontally, with the two end arms being placed vertically. The letter I-profile is thus turned by 90 degrees in the cross-section.

[0024] In this way, the profile is designed as self-supporting on roller bearings. The I-profile is also very strong in terms of construction and offers the most effective security against bending or breaking.

[0025] The free end of the profile has an assembly for mutual locking.

[0026] In a particular embodiment, the mutual locking ensures that the free ends of the two extended profiles are connected to each other so that the connection will not loosen in the event of a possible impact, or that the profiles cannot be retracted. In this way, the entrance to the road is blocked with two concrete blocks, one on each side of the road, and with two extruded profiles.

[0027] According to another embodiment, the free end of one profile is mutually locked with another concrete block. In this way, the entrance to the roadway is prevented by only one concrete block with a profile that can be pulled out.

[0028] Other versions are possible where two concrete blocks are placed next to each other with a profile that is pulled out in the other direction. Many other settings are possible with a few concrete blocks.

[0029] According to the preferred embodiment of the device according to the invention, two concrete blocks are provided, each with one side of the entrance to the road, where each concrete block has a profile that can be pulled out towards the other block.

[0030] Preferably, in a device with two concrete blocks, the free ends of the profiles extending towards each other have mutually locking means.

[0031] Preferably, such means consist on one side of a V-shaped receiving part and on the other side of a flat part located between the legs of the V-part, both of which are mutually locked by means of a locking pin.

[0032] Interlocking must fulfill one important requirement: that it does not break in the event of an impact or that the connection does not loosen. Additionally, it must not be possible to manipulate the interlocking.

[0033] According to a particularly preferred embodiment of the device according to the invention, the V-shaped part on the first profile contains two plates made on the middle rod of the I-profile, wherein the plates at their ends have a tip that bends and moves away from the second tip, wherein the first plate is welded to the top of the middle rod, while the second plate is welded below the middle rod, whereby the second I-profile can be placed so that the end of the middle rod is located between both plates.

[0034] According to another particularly preferred embodiment of the device according to the invention, the means for mutual locking contain the following parts: a locking pin and corresponding openings for a locking pin made on both V-shaped parts of the first profile and at the end of the second profile; wherein the locking pin has at its tip an interlocking portion A consisting of a flat plate with a welded piece; while the profile with a V-shaped part has a complementary part B for mutual locking that connects to the flat plates with a welded part; wherein the flat plate has an opening for a locking pin which aligns with the openings when locking;

[0035] It is desirable that both parts for mutual locking have an upright edge made in the form of a semicircle and that together they form an upright edge in the shape of a circle; wherein both interlocking portions have a vertical upright edge in the center of the virtual circle, the upright edges lying opposite each other when interlocking is established.

[0036] It is preferable that the device also has a circular closure which is carried out within the circumference of the vertical edge of the circle formed by both parts for mutual locking when the locking pin is placed in the corresponding openings of the closed profiles. In the center of the lid, there is a groove designed to accept vertical uprights. The shutter has an optional lock.

[0037] The profile has a stop made at the other end of the concrete block.

[0038] The limiter prevents the profile from sliding through the concrete block, which would separate the profile from the concrete block.

[0039] According to a certain embodiment of the device according to the invention, the free end of the profile is supported on the supporting block.

[0040] Such a supporting block can be a slightly lighter concrete block on which the profile can be supported and which can be locked. Such a supporting block can be used to support one or two ends of the profile.

[0041] According to a preferred embodiment of the device according to the invention, the concrete block has two recesses made at the bottom for lifting with a forklift.

[0042] The arms of the forklift during lifting are placed in these recesses so that the concrete block can be safely placed in place and removed again.

[0043] According to another preferred embodiment of the device according to the invention, the concrete block has a central recess made at the bottom in order to be fixed to the column in a vertical position with respect to the ground.

[0044] The concrete block is then placed on a pillar or other vertical solid structure, so that the concrete block cannot be moved safely. This provides additional security. The column can also be used to ensure the correct positioning of the concrete block.

[0045] For even greater safety, several devices according to the invention can be placed one behind the other. In this way, the second set of interlocking concrete blocks can be placed directly behind, or at a distance of, for example, 5, 10 or 20 m from the first set of interlocking concrete blocks. Concrete blocks and/or profiles placed one behind the other can eventually be mutually locked.

[0046] According to another alternative embodiment, two concrete blocks can be used for one profile, whereby the profile can extend through both concrete blocks so that it rests on them. For this purpose, the concrete block on its side (below, where the profile extends) has a connector, that is, a cylindrical recess with an internal thread intended for connecting the concrete blocks to each other in a fixed way.

[0047] According to another embodiment, several profiles can be provided for each concrete block, which can be extracted, e.g. placed at the same height one behind the other, viewed from the perspective of the oncoming vehicle, and/or the profiles may be located at different heights.

[0048] The procedure for preventing entry into the road using the device according to the invention contains the following steps:

a) Placing two concrete blocks with profiles that can be pulled out from the sides of the entrance to the road,

b) Extracting the profile over the entrance to the road,

c) Optional mutual locking of free profile ends.

[0049] The procedure for quickly enabling entry into the road using the device according to the invention contains the following steps:

a) Optional unlocking of the free ends of the profile,

b) Inserting the profile through the concrete block.

[0050] In order to better show the characteristics of the invention, in the following text, in the form of a non-limiting example, a preferred embodiment of the device for preventing entry to the road according to the invention is described, with reference to the attached pictures of the drawings on which:

Figure 1 schematically shows a preferred embodiment of the device according to the invention with two concrete blocks;

Figure 2 shows a cross-section in the longitudinal direction of a concrete block along the line II-II of Figure 1;

Figure 3 shows a cross-section of a concrete block in the transverse direction along line III-III from Figure 1;

Figure 4 schematically shows the preferred way of realizing the locking of the ends of the profile;

Figure 5 schematically shows the preferred way of realizing the bearing block intended to carry the ends of the profile; and

Figure 6 schematically shows the preferred way of realizing locking according to Figure 4.

Figure 1 shows a preferred embodiment of the device 1 according to the invention with two concrete blocks 2. Each concrete block 2 is placed on the side of the road entrance. Each concrete block 2 contains a (partially) extruded profile 3.

[0052] A concrete block weighs, for example, 3,500 kg and contains 1,438 m<3> of concrete.

[0053] The free elongated ends 4' of each profile contain means 6 for mutual locking, one in the form of a V-shaped receiving part, and the other in the form of a flat part that can slide between the arms of the V receiving part when the profiles 3 are drawn towards each other.

[0054] At the other end 4'' of the profile 3, a stop 5 is made, so that the end of the profile 4'' stops on the concrete block during extraction.

[0055] Figure 2 shows a cross-section of the concrete block 2 made in the longitudinal direction along the line 11-11 of Figure 1. This shows how the I-profile 3 is placed so that it can be pulled out over two roller bearings 7 performed at the ends of the concrete block 2. The roller bearings have rollers that roll directly on the central part of the profile 3.

[0056] The concrete block 2 contains two recesses 8 which are made at the bottom of the concrete block and are intended for accepting the fork-lift teeth. A recess 10 is also made in the lower center of the concrete block for placing the concrete block 2 on the pillar or for vertical anchoring 9. The pillar is anchored in the ground 11.

[0057] Figure 3 shows a cross-section of a concrete block 2 made in the transverse direction along the line 111-111 from Figure 1. The profile 3 is supported by roller bearings 7.

[0058] The concrete block 2 has a recess 10 intended for a column 9 or vertical ground anchoring 11.

[0059] Figure 4 schematically shows the preferred embodiment of the assembly 6 for mutual locking of the two ends of the 4' profile. The interlocking assembly consists of a receiving part formed in the form of the letter V at the first end of the profile and a flat part formed at the second end of the profile which can slide between the legs of the receiving part in the form of the letter V when the profiles 3 are drawn towards each other. The interlocking is such that the holes 12 must be aligned against each other so that the locking pin 13 can be placed in the holes and thus block both profiles.

[0060] Figure 5 schematically shows the execution of the alternative block 14 for carrying the ends of the 4' profile. The free ends are thus additionally supported.

[0061] Figure 6 schematically shows a preferred version of the assembly 6 for mutually locking two I-profiles 3 according to Figure 4.

[0062] One I-profile 3 (the left profile in this example) has a part 15, 16 made in the shape of the letter V. In this sense, two plates 15, 16 are made on the middle bar 17 of the I-profile 3. The two plates 15, 16 have a tip 18 at their end which bends and moves away from the other, thereby increasing the space between the plates viewed towards their end. Plate 15 is welded to the top of the middle rod 17, while plate 16 is welded to the bottom of the middle rod 17.

[0063] Optionally, through the welded plates 19 carried out on the middle bar, an additional distance is formed between both plates 15, 16 so that the V-shaped part has the necessary width needed to accept the end 4' of the second profile 3 which is also mutually locked. Both plates 15, 16 are reinforced and fixed to the middle rod 17 by means of two screws/nuts 20 placed in the provided openings 21. As a consequence, the connection of the interlocking assembly is prevented from breaking in the event of a possible impact.

[0064] The second I-profile 3 (the right-hand profile in this example) extends with the end 4' of the middle rod 22 inside or between the parts 15, 16 made in the shape of the letter V. In order to compensate for the width between both V-parts 15, 16, and as an additional reinforcement against tearing during impact, the end 4' of the middle rod 22 has a welded plate 23.

[0065] The corresponding opening 24 for locking, intended for receiving the pin 25, is made in two parts 15, 16 in the shape of the letter V of one profile 3, and at the end 4' of the other profile 3 (as well as in the welded plate 23). When both ends of the 4' profiles are pulled through each other, when both I-profiles are touching or almost touching, the openings 24 fit into each other and it is possible to pass the locking pin 25 through them.

[0066] The locking wedge 25 has at its tip an additional interlocking part A consisting of a flat plate 28 with a welded part 26, 27. The profile 3 with a V-shaped part 15, 16 has a complementary interlocking part B welded to the profile 3 via a flat plate 31. The flat plate 31 has a welded part 29, 30. The flat plate 31 it also has an opening 32 for a locking pin 25. When locking, the opening 32 is aligned with the openings 24.

[0067] Both parts A, B for mutual locking contain an upright edge 26, 29 made in the shape of a semicircle and together form an upright edge in the shape of a circle. In one part the semi-circle is interrupted to make room for the lock 35. Both interlocking parts also have a vertical upright edge 27, 30 in the center of the virtual circle. These vertical edges 27, 30 lie next to each other when the mutual locking is established.

[0068] When the locking pin 25 is placed in the corresponding openings 24, 32 of the extended profiles 3, the circular closure 33 is located within the circumference of the vertical edge 26, 29 of the circle formed by both mutually locked parts A, B. The groove 34 is made centrally in the closure 33 which is slidably placed over the vertical vertical edges 27, 30. After that, the closure 33 is locked with locks 35, so the lock cannot be opened without having the key or code.

1

[0069] The locking pin 25 can be attached via the welded ring 36 and the chain for the welded ring 36 of the profile 3. Indeed, the pin 25 is the only free part in the whole assembly.

[0070] Both ends of the 4' profile have a handle made in the form of a cylindrical rod intended for pulling out or retracting the profile. This action is performed manually and can easily be performed by one person.

[0071] At the right end 4' of the profile, where the end enters the part of the second profile 3, which is made in the shape of the letter V, there is a stop 5 in order to soften the impact during extraction.

[0072] In the event of a possible collision of the vehicle with the road entry prevention device, the interlocking assembly will not break or crack. Profiles and joints can be somewhat deformed, but they cannot be broken. Concrete blocks can move somewhat if they are not anchored to the ground.

[0073] The crash test was conducted on a device for preventing entry into the road consisting of two concrete blocks with a mutual distance of 11 m and two interconnected steel I-profiles 140x140. Each concrete block measured 2.18 m x 1.10 m x 1.10 m and weighed 4 tons. The lorry weighed 7.5 tonnes and was traveling towards the barrier at an oncoming speed of 48 km/h. Two seconds after the impact, the truck stopped 13m behind the road entry device. The profile interlocking assembly remained intact. The profiles were bent around the truck and the concrete blocks moved slightly towards each other.

[0074] The subject invention is in no way limited exclusively to the embodiments described here as an example and shown in the drawings, but the device according to the invention can be realized as defined by the requirements, in all kinds of variants and without deviating from the scope of the invention.
