Definitions

• the invention relates to a safety device for persons having to intervene near railroad tracks.
• Railing-type devices have also been proposed, which are more or less easily fixed on a rail, and allow the positioning of a barrier at a safe distance from the track, without however hindering the movement of trains on this track.
• WO2010 / 1 14367 proposes to fix by magnetism, on the outside of a rail, a horizontal support for maintaining, at a predefined distance, a vertical barrier. Operators can not physically approach the railway.
• the attachment of the guardrail device proposed in this document is rapid, limiting the periods when the operators take a risk, but its use is however limited to an open area near the track. This system can not be applied to an area where there is a lane crossing, or another adjacent lane.
• the present invention provides a railing for persons operating on railway tracks, comprising a protective barrier with at least one upright and an arm mounted on the amount of the barrier and provided with a barrier fixing end to a track of the railroad track, characterized in that the amount of the barrier has an adjustable height and the fixing arm is arranged to have an adjustable length and is shaped so that the fixing end of the rail and the amount of the barrier can be arranged on either side of a rail.
• a rail is here a profiled steel bar, generally I-shaped and whose vertical part is called "soul".
• rail the whole width of the track along which one or more railroad tracks can be installed, as well as the aisles, switches or switch stations, is more broadly defined here.
• the attachment end is pivotally mounted on the arm.
• the fixing end of the barrier comprises a magnet arranged for desmodromic cooperation with a rail.
• the desmodromic term here implies a cooperation of form of two elements.
• the amount is telescopic.
• the arm is telescopic.
• Figure 1 is a schematic side view of the railing of the invention in combination with a rail
• Figure 2 is a schematic view of a fixing end of the arm according to the invention
• Figure 3 is a perspective view of the railing of the invention disposed at a crossing of lanes.
• a railing 1 comprises a protective barrier 10 with at least one upright 6 and an arm 5 mounted on the upright 6 of the barrier and provided with a fixing end 2 of the barrier to a rail 4.
• the upright 6 comprises a telescopic foot 7, which allows the height adjustment of the upright 6, thanks to the locking piece 8.
• the fixing arm 5 here comprises a forearm 9, telescopic, which allows adjustment in length, thanks to the locking element 1 1.
• the barrier further comprises two horizontal bars 12, here removable and supported by hooks 13, integral with the amount 6 of the barrier.
• the fixing end 2 is here a magnet which conforms to the shape of the core 3 of the rail 4 and adheres to it by magnetism.
• This fixing technique makes it possible to fix the barrier 10 securely to the rail 4 without hindering the movement of a train on this rail.
• the magnetic force of this magnet 2 may be sufficient to support the weight of the structure 1.
• the height of the foot 7 can be adjusted to the reliefs of the ground caused by example by the presence of ballast, or the sleepers of another way. For example, holes can be punched in the foot 7 and the post 6 of the barrier and, when holes are aligned, a metal rod 8 can be slid there to pass through these parts, thus preventing the foot 7 from sliding in or out of the upright 6.
• a similar locking system 1 1 may be envisaged at the support arm 5, to adjust the length.
• the entire structure is thus fully adjustable to the reliefs of the ground, and can also easily disassemble for easy storage and transport.
• Blocking parts 8 and 1 1 are here described for fixing the telescopic parts, but any other means for adjusting the height of the upright and / or length of the arm 5 are conceivable.
• a bore could allow adjustment by screwing the elements together.
• the magnet 2 may comprise one or more magnetized elements held together by means known to those skilled in the art.
• several magnets can be embedded in a metal casing, which is also the point of junction with the arm 5.
• the magnet 2 is connected to the arm 5 via a hinge 14, as shown in FIG. Figure 2, the arm 5 can then rotate vertically (as indicated by the dotted lines), which gives the railing 1 a greater adaptability to the reliefs or obstacles that may be present.
• the hinge could also be positioned to allow the support arm to pivot laterally.
• the railing 100 is constituted by three structures each respectively comprising a magnet 201, 202 and 203, an arm 51, 52 and 53 and a post 61, 62 and 63 barrier.
• Vertical locking elements 81, 82 and 83 make it possible respectively to adjust the length of the feet 71, 72 (not shown) and 73 of the uprights 61, 62 and 63.
• Horizontal locking pieces 1 1, 1, 12 and 13 allow to adjust respectively the length of the arms 51, 52 and 53.
• the structure 100 is installed at a switch between two tracks formed, on the one hand, by the rails 40 and 41 and, on the other hand, by the rails 42 and 43.
• the arm 51 is here shown passing over the rail 42, the support arms 52 and 53 pass over the rail 43.
• the railing 100 makes it possible to protect operators carrying out work just next to the rail 43. This is made possible by the fact that the arms can pass over the rails 42 and 43, thanks to their bent end, and be adjusted in length, without compromising the stability of the structure.
• the great flexibility of the railing of the invention, and in particular the fact that it can be fixed on either side of one or more other rails, allows its use in a large variety of configurations, and even in the presence of obstacles or land terrain.
• the structure could be manufactured so that a predefined safety distance between the fastening end 2 and the barrier 10 is always kept to a minimum.
• FIG. 1 illustrates a perpendicular arrangement of the support arm 5 and of the upright 6
• FIG. 3 illustrates oblique ends of the support arms 51, 52 and 53 welded to the uprights 61, 62 and 63.
• Many other configurations are possible, they can also, for example, be connected by hinges or nest into each other.
• the horizontal bar 12 forming, with the amounts 61, 62 and 63 railing barrier can be held in place on these amounts by multiple techniques. It may for example be welded, screwed, placed on hooks 13 or threaded into orifices judiciously placed on the uprights.
