Definitions

• the present invention relates to a device for protecting a user in the event of a fall in a substantially vertical track such as a ladder.
• This device is for example usable on a tank vehicle, or a container, the constitution of which obliges the user to climb onto the upper part to access the loading members.
• substantially vertical path means any path taken by the user to move, in a substantially vertical direction.
• This track can be arranged as a ladder, a stepladder, a staircase, a vertical or sloping wall provided with steps and / or sockets, a ' via ferrata, or even a pylon along which sockets and / or steps are planned.
• This route can be arranged as a wooden post or a tree along which the examiner can climb using claws.
• a device for protecting a user in the event of a fall in a substantially vertical track comprising a harness equipped with a self-locking reel with automatic return of a link having a free end provided with means for hooking to a guide element extending along the substantially vertical path between a lower part and an upper end thereof, the device comprising abutment means of the hooking means, the abutment means being movable along the guide element between the lower part and the upper end of the substantially vertical track and immobilizable in the vicinity of the upper end of the track appreciably vertical.
• the user can bring the attachment means at the upper end of the substantially vertical track and immobilize it.
• the link like a strap, is gradually wound or unwound.
• the body of the user exerts a violent traction on the strap which causes the actuation of the locking means of the self-locking dispenser.
• the height of the fall is then reduced to the length of strap which is unwound under violent traction before the 'locking means come into action. Given the rapidity of actuation of the means for blocking the current reels, this length is very limited.
• the abutment means comprise a pole having one end arranged to cooperate by sliding with the guide element - and bear under the hooking means, and means for fixing the pole the along the guide element.
• the guide element thus facilitates the handling of the pole.
• This embodiment is particularly simple, quick to implement and robust.
• said end of the pole is provided with a stirrup extending around the guide element.
• the stirrup guides the end of the pole which is therefore particularly easy to handle.
• the abutment means comprise at least one pulley mounted in the vicinity of the lower part of the substantially vertical track, at least one pulley mounted in the vicinity of the upper end of the substantially vertical track, a flexible element extending in a loop around the two pulleys, a support element mounted to slide on the guide element and connected to a strand of the flexible element and means for locking the flexible element in position when the support element is at near the upper end of the substantially vertical track.
• This embodiment is also very simple and robust. It allows to equip substantially vertical tracks of greater width than with the previous embodiment. Other features and benefits of the invention will emerge on reading the following description of particular non-limiting embodiments of the invention.

• the fixed line 5 is formed of a cable having ends 6 (only one of which is visible in the figures) which are fixed in a manner known per se to the vehicle so as to keep the fixed line 5 in tension.
• the fixed line is supported at regular intervals by anchoring elements generally designated in 7, 8 each comprising a tube 9, 10 which receives the fixed line
• the tube 9 of the anchoring element 7 has the shape of a butt which comprises one end in the extension of the vertical section 5.1 and one end in the extension of the horizontal section 5.2.
• the tube 9 fixing means comprise a collar 13 fixed to an upper end of a ladder post 2 and a sole 14 screwed or welded to the roof 4 of the vehicle 1.
• Several anchoring elements 8 (but only one is visible in the figures) are distributed along the horizontal section 5.2.
• the fixing means are soles 15 screwed or welded to the roof 4 of the vehicle 1.
• a slide generally designated at 16 "(or mobile anchor point according to the above-mentioned standard) is mounted to slide on the fixed line 5.
• the slide 16 known in itself, comprises a tubular body 17 along which is formed a slot 18 allowing the lateral introduction of the fixed line 5 into the body 17.
• Known retractable means (not visible in the figures) are provided to prevent the passage of the fixed line 5 in the slot 18.
• a ring 20 is integral with the body 17. The ring 20 is positioned relative to the slot 18 so that, when the ring 20 is pulled to move the slide 16 along the fixed line 5, the slot 18 allows the passage of the lateral fingers 11, 12 (see FIG. 7).
• anchoring element 7 in the form of a stick ensures the continuity of the sliding of the slide 16 between the vertical section 5.1 and the horizontal section 5.2.
• the protection device comprises a harness 21 intended to be worn by the user and equipped with a self-locking reel 22 and with automatic return of a strap 23.
• the reel 17 is known in itself -even.
• the strap 23 is here associated with an energy absorber and has a free end provided with a carabiner 24 allowing the strap 23 to be hooked to the slide 16 and therefore to the fixed line 5.
• the protection device comprises means for stop which are movable along the vertical section 5.1 between the lower part and the upper end of the ladder 2 and immobilizable in the vicinity of the upper end of the ladder 2.
• these abutment means comprise a tubular pole 25 having ends 26, 27 arranged to removably receive pins 28, 29 secured to the vehicle 1 so that once received between the pins 28, 29 the pole 25 extends parallel to the vertical section 5.1 of the fixed line 5.
• the ends 26, 27 and / or the pins 28, 29 can be sheathed with a vibration-absorbing material.
• the end 26 is provided with a stirrup 30 in which the vertical section 5.1 passes.
• the end 27 and the corresponding pin 29 are pierced transversely to receive a pin 31 to make the pole 25 integral with the vehicle by opposing its release from the pins 28, 29.
• the user 3 removes the pin 31 and disengages the pole 25 from among the pins 28, 29 to bring the end 26 to the bottom of the ladder 2 (see Figure 6 ).
• the slide 16 being mounted above the stirrup 30, the user hooks the carabiner 24 to the ring 20 then manipulates the pole to engage it again between the pins 28, 29 before replacing the pin 31 (see Figures 5 then 1 and 3).
• the vertical section 5.1 guides the slide 16 and the end 26 of the pole 25, which facilitates its handling.
• the bracket 30 and the slide 16 are then adjacent to the upper end of the ladder 2 (FIG. 2) and the bracket 30, held in position by the pole 25 i - mobilized by the pins 28, 29, forms a stop opposing any movement of descent of the slide 16.
• the stirrup 30 and the pole 25, by blocking the slide 16 stops the fall of a user who would have fallen from the ladder. The user can then climb the ladder 2 while being insured and then access the roof 4.
• the stop means comprise a pair of pulleys 40 mounted on the vehicle 1 in the vicinity of the lower part of the ladder 2 and a pair of pulleys 41 mounted in the vicinity of the high end of the ladder 2.
