Definitions

  • This invention concerns a separator element or road stud intended to form a barrier.
  • the barrier is produced by juxtaposing such separator elements by an articulated connection.
  • This barrier is intended for delimiting roadways or race tracks, parking areas, piers, airstrips, etc., as well as for protection of users, in other words, drivers, pedestrians, pilots, or spectators, especially by restraining vehicles in case they leave the track.
  • the invention also concerns a manufacturing method of such a barrier and of the separator elements claimed that form the barrier.
  • the invention proposes solving this problem by making a separator element whose mechanical properties and, more particularly, its damping and shock-resistant functions, are greatly improved.
  • a separator element that has an oblong horizontal section comprising a cover, preferably made from plastic, supple and flexible, containing a central reinforcement or hollow core in its middle section, preferably metallic, made as a flattened sheath extending from one end to the other of the element. Between such cover and such tubular central reinforcement, there are spaces that are filled or intended to be filled with a damping material.
  • a barrier equipped with separator elements according to the invention allows for absorbing and damping violent shocks, such as those that can occur, for example, when cars leave the track in Formula 1 car races.
  • the cover and also, preferably, the flattened hollow core of the claimed separator element are filled with a damping material, preferably consisting of plastic foam, for example, polyethylene foam.
  • this supple material in the separator element further improves shock damping and consequently reduces risk of damage that can occur in a violent collision resulting, for example, from a vehicle leaving the road or the race track.
  • the separator element in accordance with the invention, contains at least two stacked passages or orifices, made in each of its ends.
  • Such passages allowing the crossing of said element by at least two stacked links, preferably consisting of supple straps or flexible metal bands allowing to connect it to a set of identical or similar separator elements successively arranged one after the other to create a hinged barrier.
  • the ends of the flattened hollow core are laid out so as to allow the securing of at least two, and preferably three, stacked flexible metal ties, preferably constructed as flat bands, allowing the separator elements to be connected to one another.
  • each of the separator elements includes one convex cylindrical end and one concave cylindrical end, so that they may abut and be fitted successively to one another by said ends that form an articulated interlocking or cylindrical articulation with the concave cylindrical end and with the convex cylindrical end, respectively, of neighboring separator elements.
  • the manufacturing method of separator elements according to the invention intends to remove this difficulty in order to facilitate handling and shipping of such elements.
  • This goal is achieved through a remarkable manufacturing process in that it consists of producing an element comprising the cover and the central hollow core in a plant, for instance by rotary molding.
  • the introduction of the supple material into the free internal space of said separator element is done, for example, by injection on the sites where barriers are assembled and positioned after the supple or flexible links ensuring the linkage of the elements have been installed.
  • This method is particularly advantageous in the sense that it facilitates handling and shipping of the separator elements to the location where the barrier is supposed to be placed. Likewise, the manual positioning work of the separator elements, one after another, before their assembly by insertion of supple or flexible links to form the barrier, will be less onerous.
  • FIG. 1 is the elevation view of a separator element crossed by three supple or flexible links.
  • FIG. 2 is the top view of this separator element.
  • FIG. 3 is the front view of the separator element.
  • FIG. 4 is the left-side view of the separator element.
  • FIG. 5 is the right-side view of the separator element.
  • FIG. 6 is the cross sectional view according to Line 6 - 6 of FIG. 3 .
  • FIG. 7 is the longitudinal cross-sectional view according to Line 7 - 7 of FIG. 3 .
  • FIG. 8 is a top view showing an articulated barrier resulting from the assembly of several separator elements.
  • This damping separator element 1 comprises a supple cover 3 with an oblong horizontal section and a core or central hollow reinforcing piece constructed as a flattened sheath in a middle portion of the element.
  • the element has a rectangular section, extending practically from one end to the other of the element 1 , with the supple cover 3 and the flattened central tubular reinforcing piece 2 defining filled spaces or spaces meant to be filled by damping material 11 .
  • Cover 3 may be constructed of a supple and flexible material, preferably shatterproof, for example, low-density polyethylene that, besides its aforementioned qualities, has the property of appropriately tearing if it breaks, preventing its fragmentation or shattering.
  • the thickness of the cover may vary depending on the intended use of the separator elements. It may be between 5 and 8 mm, for example.
  • the reinforcing piece 2 is advantageously made of metal, preferably of steel, to provide good mechanical resistance to impacts. It may have a thickness and width that can vary depending on the intended use of separator elements. Solely by way of example, it may have a thickness on the order of 2 mm to 5 mm and a width on the order of 1 cm to 10 cm. It extends approximately over the entire height of the element.
  • the central reinforcing piece 2 is integrated into cover 3 , when the latter is constructed, for example, by a known rotary moulding process.
  • Separator element 1 thus obtained, has, for example, a height on the order of 1200 mm, a length of 1500 mm and a width of 600 mm.
  • Cover 3 consists of lower and upper bases comprising, for example, a wide oblong rib 4 .
  • These ribs 4 are designed, on the one hand, to reinforce the rigidity of said cover 3 and, on the other hand, to incorporate, for example, a logo or other distinctive sign.
  • Cover 3 in other words, separator element 1 , comprises a convex cylindrical end 5 and a concave cylindrical end 6 , with an identical radius, connected by two large flat lateral and parallel faces 7 .
  • each of the two ends 5 and 6 of the damping separator element has at least two and, preferably, three passages or orifices, respectively 8 and 9, preferably stacked and spaced at regular intervals, formed in a vertical rectangular shape, and arranged in the median vertical plane P-P of separator element 1 .
  • These passages or orifices 8 and 9 allow the crossing of cover 3 and reinforcing piece 2 by three supple or flexible links, advantageously and preferably consisting of straps or flat bands 10 .
  • These bands or straps may advantageously have a width on the order of 50 mm and are arranged so that their width is placed in a vertical or substantially vertical plane, as notably shown by FIG. 1 .
  • the supple straps may be made from synthetic fabrics or fibers, such as polyamides, polyesters or others, and they have, in this case, a certain stretching capability, playing a role in shock damping.
  • Flexible bands 10 may also consist of metal bands, for example, steel or other metal types of strips.
  • Orifices 8 or 9 are arranged one near the upper edge of the element, another near the base of the latter, and the third one at mid height of said element.
  • the straps or flat bands 10 cover the entire height of the barrier and any tendency of the elements to rotate or of the barrier to twist in case of impact is thereby eliminated.
  • Flat bands or straps 10 allow connecting multiple identical or similar separator elements 1 A, 1 B, 1 C, . . . , 1 N, interlocked one after the other to make an articulated demarcation or protection barrier ( FIG. 8 ) in which the configuration can be quickly and easily adapted to the needs.
  • the ends of the flattened hollow core or central reinforcing piece 2 are laid out to allow the attachment, for example, in a detachable manner, of flexible metal ties, preferably made as flat bands, to connect the elements to one another.
  • the ends are matched in a complementary way to allow for this attachment.
  • the attachment of these flexible metal ties on two successive elements may, for example, be done by bolts or some other form of assembly.
  • Separator element 1 finally comprises a supple damping material 11 , preferably made of plastic foam, for example, polyethylene foam, filling the empty space between cover 3 and reinforcing piece 2 , as shown by FIGS. 6 and 7 .
  • the internal space of reinforcing piece 2 may also be filled with this supple dampening material 11 , notably in the case where said reinforcing piece 2 has a width of more than 5 cm.
  • an element is proposed to be built, in an initial phase, comprising cover 3 and flattened central tubular reinforcing piece 2 in a plant, for example, by a rotary molding process.
  • the second phase consists of filling cover 3 and hollow core 2 with damping material 11 , being performed, for example by injection, on site, i.e. where the barriers are assembled and positioned, after installation of supple or flexible connecting links 10 .
  • the separator elements are, first of all, arranged adjacent to one another, then straps 10 are inserted across each of them, in other words, through passages or orifices 8 and 9 , so that they cross the reinforcing piece 2 and cover 3 of each separator element 1 lengthwise.
  • the ends of said reinforcing piece provide a common opening or individual openings for this purpose, allowing the passage of straps between the large vertical faces of the latter.
  • the supple damping material 11 is inserted in separator element 1 by injection through one or several orifices (not shown) made in cover 3 , preferably in its upper wall.
  • one or several orifices are made in one of the walls of said reinforcing piece 2 , preferably in its upper wall, to allow penetration of said supple damping material 11 into the internal space of said reinforcing piece 2 .
  • This injection is preferably performed under pressure so that the damping provided by the supple damping material 11 will be optimal in case of impact.
  • barriers or portions of barriers consisting of multiple elements, for example, of thirty elements assembled one after another, with the barrier portions thus obtained being themselves able to be assembled through truss rods known as such.
  • separator elements Because of the junction of separator elements through a ball and joint or cylindrical articulation, these elements can have various inclinations in relation to the other ones so that it is possible to quickly install straight or curved protective barriers with radii that are more or less short, depending for example on the layout of tracks or circuits.
