Description
- The present invention relates to a anti-crashing safety device, particularly for road guard-rails.
- More particularly, the invention relates to a device of the above kind that allows to make integral all the elements realizing a guard-rail.
- At present, the protection solutions employed are made up of sheet strips, having a different shape in function of the different cases, which abutted longitudinally and supported by evenly spaced poles.
- Unfortunately, in case of crashes, this kind of solution, wherein the single elements are coupled by few bolts, detach and often fold, yielding under the load due to a violent crash, so that the vehicles and particularly the trucks, invading the opposed lane, with the tragic unavoidable consequences.
- In this context can be inserted the solution suggested according to the present invention that allows to avoid that the above structural yielding of the protection occurs following to a violent crash.
- The anti-crashing device for road guard-rails according to the invention can be advantageously in any application connected to the road safety, i.e. bridges, highways, mountain roads, etc., i.e. in any case it is necessary to strengthen the existing protections or those to be installed, making them suitable to keep the vehicles on the roadway in case of impact, accident, etc.
- The solution suggested according to the present invention has the main object to make integral the single elements comprising the road protections or barriers (guard-rails), so as to avoid their crashing in case of impact and so as to deviate upward the barrier.
- These and other results are obtained according to the present invention by a solution providing the adoption of one ore more tension wires placed close by the elements of the protection, as well as a coupling system of the single elements of the barrier with the support poles determining a deviation upward the barrier and stretching said tension wires.
- It is therefore specific object of the present invention a anti-crashing safety device, particularly for road guard-rails made up of a plurality of elements suitably shaped, coupled each other along the longitudinal direction and fixed in the ground by poles and like, said device comprising at least a tension wire fixed close by said elements realizing the guard-rail, provided at its ends with a fixing and/or traction device, and coupling means between said elements and said poles or like for the fixing to the ground, determining in case of crash an upward and backward motion of the guard-rail elements, and a contemporaneous maximum extensions of said at least one tension wire.
- Preferably, according to the invention, there are provided two or three tension wires, provided one above the other, even if it is possible to provide a greater number of tension wires.
- Always according to the invention, said at least one tension wire is comprised of stainless steel or other high strength material , and is fixed close by said guard-rail elements in the most suitable position, for example in correspondence of a curvature, of a technical resistance, etc. in front of or behind said guard-rail.
- The fixing of said at least one tension wire with said guard-rail can be realized by mechanical means, for example a flange.
- Further, according to the invention, said coupling means between said poles and said guard-rail elements can be made up of at least an arm, preferably two or three arms, but even more, provided between said pole and the guard-rail element, preferably upward inclined from the pole toward the guard-rail element, or having a shape suitable to allow the deviation upward of the barrier.
- Always according to the invention, more than one guard-rail can be provided vertically coupled, each one provided with its own device according to the invention.
- The present invention will be now described for illustrative but not limitative purposes according to its preferred embodiments, with particular reference to the figures of the enclosed drawings, wherein:
- figure 1 is a diagramatical view of a first embodiment of the device according to the invention;
- figure 2 shows a particular of the solution of figure 1;
- figure 3 is a diagramatical view of a second embodiment of the device according to the invention;
- figure 4 is a diagramatical view of a third embodiment of the device according to the invention;
- figure 5 is a diagramatical view of a fourth embodiment of the device according to the invention;
- figure 6 is a diagramatical view of a fifth embodiment of the device according to the invention;
- figure 7 shows a particular of a device according to the invention; and
- figure 8 shows a particular of a device according to the invention.
- Referring first at figures 1 and 2, it can be seen a first embodiment of the device according to the invention.
- In figure 1 it is shown a portion of road guard-
rail comprising poles 1, driven in the ground, and from whicharms 2 extend, upward inclined until coupling with the guard-rail element 3. - In the shown embodiment, the
pole 1 and thearm 2 are realized integral. - On the guard-
rail element 3 twotension wires 4 are provided, internally coupled with respect to the guard-rail 3, by theflange 5 well shown in figure 2. - Said
flange 5 is coupled to the guard-rail element 3 by thebolts 6. - During the first impact phase, the guard-rail has a first motion upward and a rearward motion absorbing the energy.
- In this way a maximum extension of the
tension wires 4 between two following poles is obtained. - In the solution shown in figure 3, two
parallel arms 2 are provided between eachpole 1 and guard-rail element 3. - Further, the
poles 1, thearms 2 and theelements 3 are not realized integral, but separately and then coupled each other. - The solution according to
claim 4 is absolutely similar to the solution of figure 3, with the only one difference of the shape of thearms 2. - In figure 5 is instead shown a solution providing two guard-
rails 3 vertically coupled, while in figure 6 it is shown a vertically overlapped wave shaped guard-rail 3. - Observing now figure 7, it can be noted an example of a
wire 3 close by guard-rail elements 3, by the use of theflange 5. - Finally, in figure 8 it is shown a solution wherein the
tension wire 4 is provided externally with respect to the guard-rail 3, so that in this case the flange 5' is provided externally and a similar fixing system employing a bolt 6' is used. - Obviously, this solution can be used in anyone of the embodiment already described,
- The present invention has been described for illustrative but not limitative purposes according to its preferred embodiments, but it is to be understood the variation and/or changes can be introduced by those skilled in the art without departing from the relevant scope as defined in the enclosed claims.
