Definitions

  • the present invention concerns a fixed safety ladder.
  • the device is provided so that an operator who accesses the safety ladder always remains self-insured in the climbing operation by it. At the same time there is a rapid and comfortable ascent to levels above the user's position as well as descent.
  • the device consists of two fasteners for the user's forelimbs and another two for the lower limbs that are attached to plates fixed on the element to be scaled, so that in the ascending position the fasteners behave as sliders and in the position of descent they block the movement.
  • the safety ladder has been conceived in order to obtain numerous advantages over other existing means with similar purposes in the industrial sector, wind turbines, telecommunications.
  • the device of the invention has a new structure for climbing at different levels. It consists of two anchor plates, fixed to vertical walls by means of spacer bushes, parallel to each other.
  • Four user support devices are incorporated thereto, two for the forelimbs or hands, provided with ergonomic grip support and safety ring, and two for the lower extremities or feet provided with fastening straps. Two to two are inserted into the plates previously fixed to the wall. These devices have two positions, one of ascent in which it is sliding, and another of descent in which the device locks by lever with the plate in that same position. In this way
  • SUBSTITUTE SHEET Each device performs the locking / unlocking independently so that the ascent / descent maneuver is carried out with total freedom and always at the user's request.
  • the handholding devices have a safety ring to anchor the user's harness there.
  • these four devices are portable, they are anchored to the plates to be part of the safety ladder, and at the end of use they are separated from the structure with which the ladder is rendered useless to other users when that is what is intended. In the same way these devices can be used in those places provided with the fixed anchor plates.
  • the fixed safety ladder is constituted by the coupling of figures 2 and 3 in figure 1, so that in each fig.1 a fig.2 and a fig.3 are inserted, always fig.2 above fig. 3.
  • Two parallel plates are installed separated from each other by a distance of 40 centimeters.
  • the plates are joined together by the connecting element 2 screwed together to reach the desired ladder length in each case.
  • the plates are anchored to the wall by means of the separation / fixing bushes 4, which are attached to the plate through the perforation for fixing 3.
  • the bushes 4 are necessary to give way to the anchoring devices fig. 2 and fig. 3 along the plates fig. 1.
  • Figure 2 shows the manual anchoring device by which the user has a point of attachment to each plate fig.1 (two by stairs). It consists of an ergonomic handle 8 added to the support 7 to which the user's hand grips, all associated with the anchor armature 5.
  • the device has a tilting system so that in ascension the position is sliding fig.4 and when force downwards, sense of gravitational force, the tilting system blocks by lever effect Fig. 5.
  • the sliding position fig.4 is achieved by a roller system 6, four rollers per device, which facilitates sliding.
  • the blocking position fig.5 is achieved by exercising the device fig.2 lever effect with the plate that prevents its displacement and thus ensure its position.
  • the system fig.2 by its own weight and by the effect of gravity can block itself.
  • the device has a safety ring 9 to anchor the anchoring elements from the user's harness, so that it is permanently self-insured.
  • Figure 3 shows the anchoring device for lower extremities or feet by means of which the user of the safety ladder has a point of attachment to it for each foot, one on each plate fig. 1. It consists of support for the feet 12, in which there are fastening tapes 13 for the feet of the user, two for each device, all associated with the reinforcement of the anchor 10.
  • the device has a tilting system so that in ascension
  • the position is sliding fig.4 and when force is made in the downward direction, direction of the gravitational force, the tilting system locks by lever effect fig.5
  • the sliding position fig.4 is achieved by means of a roller system 11, four per device anchoring, which facilitates sliding.
  • the locking position fig.5 is achieved by exerting the device fig.3 lever effect with the plate fig.1 preventing its movement and thus ensuring its position.
  • the system fig.3 by its own weight and by gravity can block itself. It is not provided with a safety ring.
  • Figure 4 shows the positions of ascent and descent, sliding position. It is achieved by means of a roller system 11 associated with the anchoring devices fig.2 and fig.3, four per anchoring device, which facilitates sliding.
  • Figure 5 shows the locking positions that support.
  • the blocking is caused by the lever effect of the anchoring device fig.2 or fig.3 with the plate f ⁇ g.1

Abstract

L'invention concerne une échelle fixe de sécurité qui présente une nouvelle structure pour monter à un certain niveau. Ladite échelle comprend deux plaques d'ancrage parallèles, fixées à un parement. Quatre dispositifs permettant de soutenir un utilisateur sont insérés dans lesdites plaques : deux pour les mains, équipés de poignées ergonomiques et d'un anneau de sécurité; et deux autres pour les pieds équipés de sangles de support. Deux positions sont proposées, à savoir une position de montée/descente coulissante, et une autre dans laquelle le dispositif est verrouillé sur la plaque par un levier. Chaque dispositif est verrouillé/déverrouillé de manière indépendante, ce qui permet d'assurer la manoeuvre de montée/descente librement à la demande de l'utilisateur. Afin de garantir Ia sécurité, les dispositifs supérieurs possèdent un anneau de sécurité d'ancrage au harnais de l'utilisateur. Lesdits quatre dispositifs sont portatifs, peuvent être insérés dans les plaques pour faire partie de ladite échelle de sécurité, et peuvent être séparés de la structure après utilisation ce qui permet de rendre l'échelle inutilisable par d'autres utilisateurs.
