Definitions

• the safety barriers that escort the sides of the road, in those areas where there is a danger of a vehicle leaving the road sideways, are constituted by a metal band conveniently curved with some bionda-shaped undulation, so that they offer a facing the road without edges.
• This band is located parallel to the roadway, supported by vertical posts anchored in the ground, which at the top have a collision or other means of fixing between post and barrier.
• the object of the present invention is a device intended to protect the posts that support the guardrails that constitute the usual barrier of a road or highway, which in case of traffic accidents of two-wheelers cause serious consequences when impacting the drivers against them.
• EP 1256659 describes a hollow impact absorption cylinder, which surrounds the bionda support post along a road, consisting of a rigid, inner cylinder capable of rotating around the pole and an outer cylinder of a diameter larger, made of a soft material, which aims to resist an impact of a vehicle, or body of a person projected against said lane, to alleviate the possible damage.
• WO2005075745 discloses a protection device that has a flexible coating capable of covering the post, formed by a plastic body with a cylindrical development and an open cross-section that provides a longitudinal front opening, so that it can be mounted to embrace a Support post of a road barrier.
• the protection is essentially formed by two cylindrical walls connected by circular ribs that form an envelope that exhibits a good shock absorption behavior.
• a lining element for these posts that is soft and deformable, which absorb the energy of the impact in particular when the direction of travel of the injured person is perpendicular to the post.
• said cladding element can rotate around the post, only in the event of an impact, so that when the injured person impacts laterally, the movement of the obstacle occurs, so that when the latter moves with the injured person, the impact greatly.
• the length of these linings is such that between two Consecutive posts only a space of the order of about 30-40 cm remains. through which you can hardly strain a person.
• the accident at these points is practically eliminated by the ability to yield by turning both coatings as if the protection deforms when the impact occurs in this intermediate zone.
• this device comprises: An internal support structure, preferably of a metallic nature or of a resistant plastic or rubber, which, in section, defines a central hollow, which has a section slightly larger than that of the post that supports the bionde and a configuration similar to it.
• the shape of this hole determines that the device can be inserted into the post from top to bottom in a newly constructed barrier or in which the guardrail has been disassembled and also that it tends to remain in a position parallel to the bionda. At the same time, it must also allow a slight turn before a lateral impact, up to a maximum angle of the order of 45 e ;
• said gap has a clearance or deformation capacity sufficient to allow the structure to rotate on the support under certain conditions.
• the device mounts a flexible covering formed by two or more recycled automobile wheels, of which the central area has been cut and removed, while the remaining part has been deformed, crushing them laterally in a transverse direction to form an oval envelope around the inner support structure, in which the major axis is located parallel to the bionda or the road.
• the configuration of this coating facilitates the rotation of the device in any condition, unless the impact is exactly perpendicular to the bionde and towards the center of the post.
• this device is structured by means of a flexible and resistant band, also of oval configuration, which is placed around the interior structure, arranged to receive inside the automobile wheels, to provide said oval shape.
• a sheet or plate also soft and / or deformable, adheres or screenprinted on its outer face an horizontal bisector angle, which will indicate the direction of the road, is adhered or fixed during manufacturing.
• the inner hollow of the support structure has a substantially rectangular configuration, whose transverse sides with respect to the bionda are slightly longer than those of the post and have semi-circular face paths, which are defined by two hollow side cylinders. This configuration tends to keep the device parallel to the bionda, however, in case of impact against it, it presents the possibility that the support rotates on the pole and therefore the device as a whole, so that any impact on it it will also involve a certain turn of the same, which prevents the impact from being direct against the post, unless it is perpendicular to it.
• the outer wrapping band can be replaced by ropes, cables, or similar elements that shape the car's wheels before being introduced on the structure and during the molding and drying of the inner and outer fill, so that they maintain their form during this process.
• the band can be replaced by a non-stick coating that impregnates the mold into which the wheels and the interior structure are introduced before molding and drying the filling, so that it is this that amalgams and maintains the shape of the device once it dries.
• the wheels can be replaced by chopped rubber or in pieces, from recycled vehicle wheels.
• the first coating after the rigid interior structure is flexible and therefore allows the impact of a person or object on it to be reduced; while the outermost lining is deformable to impact, or soft, so that it absorbs the force of the impact on it and together prevents damage to the accident.
• the support structure is open in the central area, just in the part corresponding to the bionde support post.
• the elements that make up the lining of the device are open defining a vertical window in the entire height of the device.
• the degree of deformation of the car wheels inserted in its manufacture, together with the configuration of the band flexible exterior is such that its major axis has a length that leaves a space between 10 and 50 cm between two devices placed on two consecutive posts, that is, a space that does not allow the passage of a person or that, if produced, stops It happened considerably.
• Figure 1 shows a perspective view of a barrier (1) provided with the device of the invention on one of the support posts (2) of said barrier.
• Figure 2 shows a perspective view of all deployed device components.
• Figures 3 and 4 show two perspective views of the manufacturing process of one of these devices, simulating at the same time that it is mounted on a pole (2).
• Figure 5 represents a section of road in which two devices have been placed on two consecutive posts.
• it is a device to protect the posts (2) that support the biondas or guardrail barriers (1) that are placed at certain points of a roadway to prevent vehicles from getting out of the way In the event of an accident, but that in itself, they constitute an added problem when the injured person is a cyclist or motorcyclist who impacts against these posts.
• the basis of this device lies in the reuse of used standard car wheels, which not only solves the problem of the protection of the posts, but also of giving way to this type of recycled products, whose reuse and relocation results usually difficult and expensive.
• the device comprises a core (3) that defines an inner hole (31) according to the post (2), so that it can slide inside to introduce the device from top to bottom when the bionda (1) is in the process of installation or disassembled It is envisaged that the length of this gap is slightly greater than that of the post (2) and that the larger sides be rounded, so that the post (2) faces a lateral force, such as that which would occur in case of impact on the device, you can rotate an angle of approximately 45 e .
• this interior structure (1) is formed by two welded tubes (32) with a certain separation by means of two parallel plates that define the internal hollow (31).
• a sheet (6) is placed on which an angle (61) has been engraved or screen printed to be placed in the direction of the road. In fact it is not necessary to manufacture two different models for left and right, since the device is reversible.
• This sheet (6) can also be a plate of a polymer similar or equal to that of the inner padding, in which case it will be placed on the flexible strip (5) before applying it so that it is embedded in it.
• the device has an envelope to the oval section post (2) having a length between 70 and 90 cm. so that, in a standard installation of a bionde (1) in which the spacing between posts is between 100 and 120 cm., the gap between two consecutive devices will be between 10 and 50 cm., so such that if the injured person impacts just in the hollow, it is stopped without being able to pass to the other side of the bionda, off the road.
