Definitions

• the present invention refers to a system for the protection of motorcyclists and more specifically to those generically referred to as containment barriers that are located on the roads.
• Circular Order 321/95 T and P includes a specific system for the protection of motorcyclists.
• Circular Order 18/2004 entered into force in which, in addition to establishing criteria for the use of motorcycle protection systems (SPM), a new system was defined in its Annex for motorcycle protection developed by the Directorate General of Roads.
• SPM motorcycle protection systems
• Each pole arm is mounted in relation to one of the vertical posts; while the intermediate arm is mounted between two posts, both in "C” and tubular profiles.
• the pole arm is fixed using one of the mooring points of the upper fence to the piece that joins this fence to the post, called the separator.
• safety systems of the indicated type are already known, that is, those formed by an upper barrier that is fixed to posts through the parts called separators, providing a lower barrier, specifically designed for motorcycle safety. , which hangs on the so-called pole arms that are fixed to the posts through spacers, taking advantage of the screws that support the upper barrier to these spacers.
• the present invention proposes a pole arm that is fixed directly to the pole, both in "C” and tubular profiles, without the need to release, or adjust any part of the vehicle restraint system already installed.
• each intermediate arm is constituted by two pieces, one - TO -
• each intermediate arm has a single piece embodiment, defined by a sheet which in its upper part forms a mooring area to the upper fence; in its intermediate part it defines a bridge zone in correspondence with the location respectively of the adjacent edges of both fences; and in its inferior part it determines a zone of tie up to the inferior fence.
• the lower fence intended for the safety of motorcyclists, hanging only from such intermediate arms, that is, without the use of pole arms; so that the connection of the lower fence is made between the two posts, right in the center of the containment system, and not at the height of them, as in the rest of the solutions already known. In this way a greater ease of assembly is achieved and the system is given more flexibility.
• Figure 1 is a perspective and schematic view of the system object of the present invention, seen from the rear.
• Figure 2 is a view like that of Figure 1, but now from the front and having removed the upper fence (3) and the lower fence (5).
• Figure 3 is a profile view showing how the fixing of a pole arm (6) to a f pole (1) is performed.
• Figure 4 is the sectional view of a pole arm (6).
• Figure 5 is a front view of a pole arm (6).
• Figure 6 is a profile view showing the assembly of an intermediate arm (7).
• Figure 7 is a sectional view of an intermediate arm (7).
• Figure 8 corresponds to the front elevation view of an intermediate arm (7).
• Figure 9 is a view like that of Figure 6, but now with a lower fence (5) of different profile.
• Figure 10 is a perspective view, schematic and from the back, showing the assembly of the lower fence (5) supported only through intermediate arms (7).
• Figure 11 is a view like that of Figure 10, but now from the front and having removed the upper fence (3) and the lower fence (5), to be able to appreciate that there are only intermediate arms (7) to support the latter.
• Figure 12 is an exploded perspective view showing the mounting of a pole arm (6) on a tubular pole (1).
• Vehicle containment systems identified as "SCV" are conventionally constituted by a fence (3) which, by means of screws (4), see figure 3, is fixed to spacers (2) which in turn are fixed jointly to some vertical posts (1) nailed to the ground.
• the fence (3) has a double wave profile and constitutes a metal safety barrier.
• the vertical posts (1) are also metallic and can be both "C" profile and tubular.
• SPM motorcyclists
• This motorcyclist protection system is essentially constituted by a lower fence (5) made of sheet steel that defines a continuous metal barrier below the upper fence (3); so that this barrier closes the access of the motorcyclist before an eventual impact, ensuring that no part of the motorist exceeds the position of the system during said eventual crash.
• this lower fence (5) is mounted in the system by means of elements called pole arms and intermediate arms, the former being located in relation to the corresponding posts
• each pole arm (6) is formed by a single piece of sheet metal, which, as seen in Figures 4 and 5, determines a slightly inclined lower plane (6.1) which, in by virtue of some breaks (6.3, 6.4 and 6.5), a continuous plane (6.11) is followed, followed by a vertical plane or near the vertical plane (6.10) and a horizontal plane or near the horizontal plane (6.6).
• the lower vertical plane (6.1) has at least one hole (6.2).
• the pole arms (6) are mounted without releasing or adjusting any part of the barrier already installed.
• the lower fence (5) is tied, just in the area of the end of one of the sections that define this lower fence (5), this end that usually has four holes for the mooring of the other end of the corresponding section of adjacent lower fence (5), both ends being superimposed on each other.
• Figures 7 and 8 show how each intermediate arm (7) is formed, according to the object of the present invention, according to which, it is constituted by a metal single piece that configures an upper plane (7.1) close to horizontality , whose free edge leans against the back of the upper fence (3).
• This upper plane (7.1) is continued, after a break (7.2), in an inclined section (7.3) provided with at least one hole (7.11).
• section (7.3) there are four bankruptcies (7.4, 7.5, 7.6 and 7.7), which form a central section in bridge (7.10) and, from this, a lower section (7.8) provided with at least a hole (7.9).
• the intermediate arm (7) is fixed to the upper fence (3).
• the bridge section (7.10) is located in correspondence with the contiguous edges of the upper (3) and lower (5) fences, thus saving them properly.
• This fixing of the lower fence (5) can be carried out at any point of one of the sections that make it up or just at the overlapping part of the ends of two adjacent sections.
• the lower fence (5) can have different profiles without thereby altering the essence of the invention.
