Definitions

  • the invention relates to a device for ascending along vertical supports and a method of natural and automatic adaptation to the shape and to variations in dimensions of the support.
  • the device respects the fragility of the support (bark in the case of young trees, cables in the case of telecommunications or energy transport poles.
  • Patents There are a significant number of Patents, many of which come from the U.S. Patent, describing devices describing the solutions studied in order to facilitate the ascent of Man on various vertical supports.
  • the main faults of this device are: - not adaptable to any form of support, - non-adaptation possible during the ascent to the variation of the size of the support, causing progressively ascent, an increasing play between the belt and the support, therefore a position more and more oblique of the platforms with respect to the support, making the use of this device dangerous during the elevation, (not catching up with variations in diameter of the support), - does not allow the rotation of the device on the support, - Failure to respect the fragility of the supports, due to the shape of the support surfaces which are jammed on said support by means of rigid metal plates.
  • the main merit of this device is to have given the principle of an alternate ascent using two locking platforms on the support and whose basic principle is safe (even if the described embodiment is not) .
  • the problem we posed can be summarized as follows: - from a device comprising two platforms, the first, in the lower position, intended to accommodate the feet of the user during his vertical station, the second serving as a protective platform, possibly a seat for work, it is envisaged a manual device, the use of which remains at the free disposal of the climber, who by means of a single action on a suitable device, will allow the elongation or shortening of the belt devices and simultaneously blocking the platform , in a horizontal position, perpendicular to the axis of the support, to ensure safety.
  • Fig. 1 shows the device and the different routes of the belts, as will be explained below.
  • the bottom belt cannot be provided by the same device because the straps which have to move inside the rounded tubes cannot easily do so.
  • we opted for a mixed solution comprising a short bearing surface consisting of a reinforced strap extended by a reinforced rope, a rope allowing easy sliding inside the rounded frame.
  • Each platform is made up according to Fig. 1: - two lateral uprights, in an ovoid shape (5) similar to that of a sledge. - top and bottom belting devices, - devices for the feet and for sitting.
  • Each platform must allow: - natural adaptation to the shape of the support, without damaging it. By its principle, it greatly improves the fixing of the platform on the support by being one with it, - the permanent lengthening and shortening of the belt devices (Fig. 3), during ascent or during descent, so that the platform is constantly perpendicular to the axis of the support, giving permanent horizontal stability to the 'platform + Man, regardless of the variation in support diameter, since there is no longer any play between the belt and the support. - a natural and automatic blocking ensuring the greatest security so that any untimely unlocking is prohibited during the ascent, or the descent, or when the platform is positioned.
  • the position of the platform cannot be changed: . by taking full support on the other platform. . by actuating the locking system and, simultaneously, pulling it back, which naturally excludes any false maneuver, or any stall, when the user is in the working position, since the weight of the user does not only reinforces the wedging effect of the platform on the support. On the other hand, if the climber is on the platform, he will not be able to pull it back.
  • the user drops the 1 st platform at the foot of the support (shaft, mast, pole, ...) opens the latch (9) of junction of the upper strap (1) and surrounds the support with armed strap, then closes the strap hooking lock.
  • the operator actuates the lateral rack locking bolt (s) (8).
  • the retaining pin (15) releases the rack, retained by an elastic of the bungee cord type (12). attached to a fixed point (11).
  • the rack starts a recoil stopped when the double top (1) and bottom (3) half-belt conforms very exactly to the shape of the support (Fig. 3 and 4), as well as the lateral ovoid uprights (5).
  • the user can then release the latch (17) and the rack locking pin (15) is then positioned in one of the notches of the rack (2), thus blocking the entire moving assembly and ensuring the desired security.
  • a spring (13) keeps the body of the lock pulled down, the latter pivoting about its axis (18).
  • the tenon (15) is housed in (14)
  • the whole of the platform (5), of the belt (reinforced straps and rope 1 and 3) and lateral uprights (5) actively participate in the effort of holding the platform on said support.
  • the device remains constantly in close contact with the support, the axis of the support (01-02) remains the same whatever the variations in diameter thereof, the platform remains horizontal and substantially perpendicular to the support, which leads to a perfectly secure working position, security which does not depend on the diameter, the shape of the support, or the height of the platform on the support.
  • Figs. 3 and 4 show the position of the racks inside the uprights according to the diameter of the support and the direction of movement of the different parts of the device during a diameter take-up operation.
  • the centers 01 and 02 remain merged and that the sides (5) of the device remain tangent to the different circles at (28 and 29).
  • the two sides (5) pivot on pivots (22), fixing of a device (23) for securing the lateral uprights.
