Definitions

  • the present invention relates to a kinetic energy absorbing barrier structure.
  • barriers such as Jersey barriers or flower boxes have been installed in some cities to protect pedestrian areas and other sensitive zones to prevent or limit further terrorist attacks using motor vehicles to run into crowds.
  • Jersey barriers and other barriers in concrete or metal materials currently used to prevent access to an area by unauthorised vehicles have drawbacks and limitations of a technical and also aesthetic nature.
  • a Jersey barrier roughly 3 m long, for example, weighs approximately 1.5 - 2.0 t, while a concrete flower box can weigh from 150 kg to 900 kg depending on size.
  • Jersey barriers and other known types of barriers is constituted by the negative landscaping impact, especially when installed in old town centres, because they appear like some kind of bare concrete wall in the middle of other areas of scenic interest, namely historic, cultural or architectural.
  • FR 2 710 229 A1 describes a flower box for street furniture, actually a large box for flowers comprising a container, arranged inside the box, a mask arranged on the periphery, and a three-dimensional frame arranged between the container and the mask.
  • the mask comprises a facing element mounted removably on the frame, which can constitute a modular system such that the frame can be superimposed and/or juxtaposed with another frame.
  • FR 2 710 229 A1 describes a flower box for street furniture and not capable of acting as a safety barrier.
  • US 2009/001334 A1 and US 2006/237913 A1 describe structures that can be filled with water used as ballast.
  • the aim of the present invention is to provide a barrier structure that, first of all, is technically efficient, i.e. effectively capable of stopping a vehicle and preventing the devastating effects of a possible attack.
  • one object of the invention is to provide a barrier structure that has an extremely low landscaping impact.
  • Another object is to provide a barrier structure that can be a street furniture component and that can be integrated with different functional elements.
  • a further object of the present invention is to provide a structure that can be produced using elements and materials that are commonly available commercially and that is also competitive from an economic standpoint.
  • a barrier structure with a high capacity for absorbing kinetic energy achieved through the considerable deformability of the system combined with minimum movement on the ground.
  • the above-mentioned structure comprises a shell designed to contain a frame in which multiple weights are suitably positioned and which surrounds a tank; said tank being designed to contain a volume of water, gel or other material and also defining one or more compartments designed to contain soil for plants; said frame having a high deformation capacity.
  • the shape of the frame enables the connection of the structures with one another in various "island” or “chain” configurations, thus linking one element to the next, thereby considerably increasing the containment capacity of energy originating from impacts and further limiting movements of these structures on the ground.
  • the kinetic energy absorbing barrier structure according to the present invention comprises a shell 2 designed to contain a frame 3 that surrounds a tank 4.
  • the structure further comprises a plurality of suitably positioned weights 20 made integral with the frame 3.
  • the tank 4 is designed to contain a volume of water or gel and defines one or more compartments 5 designed to contain soil 6 for plants 7.
  • the shell 2 can be made of a plastic or metal material and is characterized by a high deformation capacity.
  • the frame 3 which is preferably made of metal, for example of aluminium or steel, also has a high deformation capacity.
  • the tank 4 which can be made of plastic for example, has at least one filler plug 8 and one or more discharge plugs 9 arranged on the bottom, for respectively introducing and discharging the water or gel 10.
  • the frame 3 and/or shell 2 have deformable rubber supports with a high friction coefficient, indicated by reference numeral 11.
  • Two or more structures 1 can be rigidly connected to each other by quick-connection means, thereby joining the various structures in a chain.
  • FIGS 6 and 12-15 show some examples of possible configurations.
  • connection could also enable fixing the structures to the ground.
  • Figures 8 and 9 show an example of quick-connection means, indicated as a whole by reference numeral 12, constituted by T-couplings 13 inserted in guides 14 made in a wall 15 of the shell 2 and capable of engaging a connection element 16 provided with suitable shaped slots 17.
  • a trolley system is provided to facilitate the handling of the structure.
  • Figure 7 shows an example of a trolley system, constituted by a trolley 18 that can be associated with the shell 2 and is fitted with retractable wheels 19.
  • the barrier structure can be assembled in situ or transported completely preassembled to the place of installation.
  • the tank 4 is filled with water, gel, or another material suitable for giving a certain weight to the structure, which shall be securely anchored to the paving due to the presence of deformable rubber supports 11 with a high friction coefficient or shall be fastened by suitable ironmongery.
  • the structure can be rigidly associated with other similar structures, as schematically shown in Figures 6 and 10 , via quick-connection means, to form a modular barrier that is substantially unmovable.
  • the barrier structure can be integrated with various functional elements, of which Figures 3-5 show just a few examples.
  • the structure can also be integrated with autonomous day and night signs, for example, via LEDs powered by solar panels.
  • the structure forming the subject of the present invention can be used to make a modular barrier, even one with complex configurations and connecting different types of functional elements, such as seats, folding seats, tables, lamps, shelters, bike racks, etc.
  • barrier modules Two examples are shown in the figures: a straight module and a circular module.
  • the structure is provided with a saw-toothed lateral edge 21, which extends along the lower outer perimeter of the base of the shell 2.
  • the saw-toothed edge 21 is configured to puncture the tyres of a vehicle that hits the structure.
  • the structure is advantageously provided with a support base with mechanical anchorage specifically studied for open agglomerate surfaces, such as asphalt for example.
  • the mechanical anchoring is obtained via saw-toothed elements 22 fixed beneath the shell 2.
  • the mechanical anchorage system enables to significantly increase the performance of the structure when the flower box stands on asphalt.
  • the saw-toothed elements 22 constitute a kind of crampon that, by biting into the asphalt, tends to block any movement of the structure.
  • the structure is advantageously provided with a chemical type of support base, specifically studied for continuous smooth surfaces, such as marble, sett, etc.
  • the chemical type support base is advantageously constituted by a biadhesive gel 23 applied on the bottom of the shell 2.
  • the locking system using a biadhesive offers the advantage of being easily reversible when the structure is mechanically detached by removing it with hoisting means.
  • a further advantage of the locking system using a biadhesive is constituted in that, unlike glues, it leaves no residues and does not damage the surfaces.
  • Figures 23 and 24 show a further embodiment of the structure 1 that comprises an orthogonal saw-toothed lateral edge 24 on the side of the shell 2 opposite to the side provided with the saw-toothed lateral edge 21, i.e. the side opposite to the side against which the possible vehicular impact is expected.
  • Figures 25 and 26 show a further embodiment of the structure 1 that comprises hidden props 25.
  • Each prop 25 is inserted within and hinged to the structure 1 at a hinge point 26.
  • a possible impact of a vehicle causes deformation of the structure and, as a consequence, the props 25 that have the hinge point on the side of impact burst through the opposite side of the structure and are driven into the ground, blocking translational movement of the structure 1.
  • a kinetic energy absorbing barrier structure has been produced that performs the task of ensuring an adequate protection from vehicles and, at the same time, constitutes an effective element of street furniture that is functional and aesthetically pleasing.
  • the device forming subject of the present invention which can be aesthetically disguised as a flower box or something else, is essentially an energy absorber that uses the water/gel not just as simple ballast, as in devices of the prior art, but rather as a means to transform, at the moment of impact, the kinetic energy of the vehicle into kinetic and potential energy of the mass of water or gel.
  • the water absorbs the energy through column dissipation and/or water choking-atomization, in practice rendering the distribution of the energy on impact harmless.
  • the structure forming the subject of the present invention can advantageously be made with recycled materials.
