Description

DISPOSITIF D'ANCRAGE POUR SYSTEME DE SECURITE ANTI-CHUTE ANCHORING DEVICE FOR A FALL PROTECTION SYSTEM
La présente invention se rapporte, d'une manière générale, à un dispositif d'ancrage sur structure rigide verticale pour système de sécurité anti-chute.The present invention relates, in general, to an anchoring device on a rigid vertical structure for an anti-fall safety system.
Plus précisément, l'invention concerne un dispositif d'ancrage pour système de sécurité anti-chute, à fixer sur structure rigide verticale au moyen d'une tige filetée munie d'un écrou, d'une tête de boulon et éventuellement d'un contre-écrou du type comportant une plaquette métallique recourbée formant deux ailes, l'une pourvue, à sa partie supérieure, d'un orifice circulaire pour passage de la tige filetée seule, l'autre comportant, à sa partie inférieure, un orifice configuré de manière à pouvoir assurer le passage de la tige filetée munie de la tête de boulon et éventuellement du contre-écrou et à permettre l'accrochage du système de sécurité anti-chute à ladite plaquette. Afin d'assurer la sécurité d'un individu lors d'une progression le long d'une structure rigide verticale, l'utilisation d'un système anti-chute s'avère indispensable. L'arrimage de ce système à la membrure s'opère généralement par l'intermédiaire d'un dispositif d'ancrage, du type décrit précédemment, qui est boulonné, à cette membrure, via l'orifice circulaire au moyen d'un boulon.More specifically, the invention relates to an anchoring device for a fall prevention security system, to be fixed to a rigid vertical structure by means of a threaded rod provided with a nut, a bolt head and possibly a lock nut of the type comprising a curved metal plate forming two wings, one provided at its upper part with a circular orifice for passage of the threaded rod alone, the other comprising, at its lower part, a configured orifice so as to be able to ensure the passage of the threaded rod provided with the bolt head and possibly the lock nut and to allow the attachment of the fall protection safety system to said plate. In order to ensure the safety of an individual during a progression along a rigid vertical structure, the use of an anti-fall system is essential. The attachment of this system to the frame is generally effected by means of an anchoring device, of the type described above, which is bolted, to this frame, via the circular orifice by means of a bolt.
Le retrait de ce dispositif, par exemple pour son remplacement, nécessite toutefois de déboulonner les boulons et de désolidariser complètement la membrure et les éléments s'y rapportant.Removing this device, for example to replace it, however requires unbolting the bolts and completely disconnecting the frame and the elements related thereto.
La présente invention a pour but de proposer un dispositif d'ancrage du type indiqué précédemment qui permette de remédier aux inconvénients précités c'est-à-dire qui puisse être fixé et enlevé aisément sans nécessité de procéder au retrait des boulons de la membrure et la désolidarisation de ses éléments, de façon à éviter toute perte de temps inutile.The object of the present invention is to propose an anchoring device of the type indicated above which allows to overcome the aforementioned drawbacks, that is to say which can be fixed and removed easily without the need to remove the bolts from the frame and the separation of its elements, so as to avoid any unnecessary loss of time.
Pour atteindre ce but, le dispositif selon l'invention est caractérisé en ce que les deux orifices communiquent mutuellement par un évidement dont les bords s'étendent tangentiellerαent à partir de l'orifice circulaire et parallèlement et en ce que la plaquette comporte, au niveau de sa face interne, une butée d'arrêt de forme circulaire centrée sur l'orifice circulaire s 'étendant extérieurement à l'évidement à partir de ses bords et dont le diamètre est supérieur à celui du cercle dans lequel peut s'inscrire le contre-écrou ou la tête de boulon.To achieve this object, the device according to the invention is characterized in that the two orifices communicate with each other by a recess whose edges extend tangentially from the circular orifice and in parallel and in that the plate comprises, at the level from its internal face, a circular stop stop centered on the circular orifice extending outwardly to the recess from its edges and whose diameter is greater than that of the circle in which the counter may fit - nut or bolt head.
Selon une autre caractéristique de l'invention, la butée fait saillie de la face interne de la plaquette c'est-à-dire de la face située dans l'angle inférieur à 180°.According to another characteristic of the invention, the stop protrudes from the internal face of the wafer, that is to say from the face situated in the angle less than 180 °.
En outre, selon un mode de réalisation préféré, la butée est constituée d'une portion annulaire telle qu'une portion de rondelle métallique faisant saillie de la face interne de la plaquette. Toutefois, selon une autre caractéristique de l'invention, la butée résulte d'une cavité pratiquée dans la plaquette par sa face interne.In addition, according to a preferred embodiment, the stop consists of an annular portion such as a portion of metal washer projecting from the internal face of the wafer. However, according to another characteristic of the invention, the stop results from a cavity formed in the wafer by its internal face.
L'invention sera mieux comprise et d'autres buts, caractéristiques et avantages de celle-ci apparaîtront plus clairement à la lumière de la description explicative ci-après faite en référence aux dessins schématiques annexés donnés uniquement à titre d'exemples illustrant des modes de réalisation de l'invention et dans lesquels : la figure 1 est une vue frontale d'un dispositif d'ancrage selon l'invention sous forme plane la figure 2 est une 'vue en perspective d'un dispositif d'ancrage selon l'invention posé sur un échelon et juxtaposé à une membrure la figure 3 est une vue en perspective du dispositif représenté à la figure 2, muni d'un contre-écrou en position de blocage Ainsi, le dispositif selon l'invention comprend une plaquette 1, avantageusement métallique, représentée plane à la figure 1, dont la recourbure permanente selon .l'axe X-Y définit deux ailes A et B, préférentiellement perpendiculaires . Les figures 2 et 3 montrent d'ailleurs clairement cette recourbure.The invention will be better understood and other objects, characteristics and advantages thereof will appear more clearly in the light of the explanatory description below made with reference to the appended schematic drawings given solely by way of examples illustrating modes of realization of the invention and in which: Figure 1 is a front view of an anchoring device according to the invention in planar form Figure 2 is a ' perspective view of an anchoring device according to the invention placed on a rung and juxtaposed to a frame FIG. 3 is a perspective view of the device represented in FIG. 2, provided with a lock nut in the locking position. Thus, the device according to the invention comprises a plate 1, advantageously metallic, shown plane in FIG. 1, whose permanent curvature along the axis XY defines two wings A and B, preferably perpendicular. Figures 2 and 3 also clearly show this curvature.
L'axe de recourbure X-Y est avantageusement choisi de manière que l'aile B se trouve en position oblique par rapport à la verticale. D'autre part, l'aile A est pourvue d'un orifice circulaire 2 pour le passage d'une tige filetée 3, représentée aux figures 2 et 3, de même diamètre, tandis que l'aile B comporte également un orifice 4 de dimension suffisante pour permettre le passage de la même tige filetée 3 munie d'un contre-écrou 5 et d'une tête de boulon 6.The X-Y bending axis is advantageously chosen so that the wing B is in an oblique position relative to the vertical. On the other hand, wing A is provided with a circular orifice 2 for the passage of a threaded rod 3, shown in FIGS. 2 and 3, of the same diameter, while wing B also has an orifice 4 of sufficient dimension to allow the passage of the same threaded rod 3 provided with a lock nut 5 and a bolt head 6.
Tel que représenté également à la figure 1 , l'orifice circulaire 2 communique avec l'orifice 4 par l'intermédiaire d'un canal sous la forme d'un évidemment 7 dont les bords 8 et 8 ' s'éloignent tangentiellement de cet orifice circulaire 2 jusqu'à faire jonction avec l'orifice 4. Conformément à l'invention, la plaquette 1 comprend en outre une butée 9 faisant saillie de la face interne de l'aile A. Cette butée 9, dont le front de butée 10 est de forme circulaire, prend l'aspect d'une portion de rondelle, avantageusement métallique, centrée sur l'orifice circulaire 2 et solidaire de la plaquette 1 par boulonnage ou soudure.As also shown in FIG. 1, the circular orifice 2 communicates with the orifice 4 via a channel in the form of a recess 7, the edges 8 and 8 'of which tangentially move away from this orifice circular 2 until joining with hole 4. According to the invention, the plate 1 further comprises a stop 9 projecting from the internal face of the wing A. This stop 9, whose stop front 10 is circular, takes the appearance of a portion washer, preferably metallic, centered on the circular orifice 2 and secured to the wafer 1 by bolting or welding.
Alternativement cette portion de rondelle peut être construite par usinage de la plaquette 1.Alternatively, this portion of washer can be constructed by machining the wafer 1.
Cette butée 9 est configurée de manière que ses bords latéraux 11 et 11' affleurent aux bords 8 et 8' de l'évidemment 7 et que son diamètre intérieur soit à la fois supérieur à celui de l'orifice circulaire 2 et semblable au diamètre du cercle dans lequel s'inscrit le contre-écrou 5 solidaire de la tige filetée 3.This stop 9 is configured so that its lateral edges 11 and 11 'are flush with the edges 8 and 8' of the recess 7 and that its internal diameter is both greater than that of the circular orifice 2 and similar to the diameter of the circle in which the lock nut 5 is secured to the threaded rod 3.
En se référant notamment aux figures 2 et 3 , on voit que le dispositif d'ancrage selon l'invention, peut être fixé sur un ensemble pré-existant formé d'une membrure 12 et d'un échelon boulonné constitué de la tige filetée 3 munie de la tête de boulon 6 de l'écrou 13 et du contre- écrou 5.With particular reference to FIGS. 2 and 3, it can be seen that the anchoring device according to the invention can be fixed to a pre-existing assembly formed by a frame 12 and a bolted rung consisting of the threaded rod 3 fitted with the bolt head 6 of the nut 13 and the lock nut 5.
Lors de la pose de la plaquette 1 sur cet ensemble, l'écrou 13 est desserré en suffisance pour, après traction sur la tige filetée 3, libérer le contre-écrou 5 qui s'éloigne de la membrure 12 d'une distance supérieure à l'épaisseur de la plaquette 1.When fitting the plate 1 on this assembly, the nut 13 is loosened sufficiently to, after pulling on the threaded rod 3, release the lock nut 5 which moves away from the frame 12 by a distance greater than the thickness of the plate 1.
La tête de boulon 6 d'abord, la tige filetée 3 ensuite et le contre-écrou 5 finalement sont alors engagés dans l'orifice 4 de la plaquette 1 amenée en butée contre la membrure 12. Par translation de la plaquette 1 perpendiculairement à l'axe de la tige filetée 3, cette tige filetée est forcée à coulisser dans le canal formé par l' évidemment 7 jusqu'à épouser le contour de l'orifice circulaire 2.The bolt head 6 first, the threaded rod 3 then and the lock nut 5 finally are then engaged in the orifice 4 of the plate 1 brought into abutment against the frame 12. By translation of the plate 1 perpendicular to the axis of the threaded rod 3, this threaded rod is forced to slide in the formed channel by the obviously 7 until marrying the outline of the circular orifice 2.
La tige filetée 3 ' est alors repoussée dans la direction de la membrure 12 jusqu'à ce que le contre-écrou 5 arrive en butée contre la plaquette 1.The threaded rod 3 'is then pushed back in the direction of the member 12 until the lock nut 5 comes into abutment against the plate 1.
L'écrou 13 est alors resserré contre la membrure 12 de sorte que le contre-écrou 5 maintenu sur la tige filetée 3 et en butée contre la face 10 de la portion de rondelle 9 provoque le blocage de tout mouvement de la plaquette 1 dans l'axe de la tige filetée 3 ou perpendiculairement à celle-ci.The nut 13 is then tightened against the frame 12 so that the lock nut 5 held on the threaded rod 3 and in abutment against the face 10 of the washer portion 9 causes the blocking of any movement of the insert 1 in the 'axis of the threaded rod 3 or perpendicular thereto.
Par la suite, le système de sécurité anti-chute, généralement constitué d'un ensemble formé de cordes, coulisseau et mousqueton, peut être arrimé à la plaquette 1 par accrochage du mousqueton via l'orifice 4.Thereafter, the anti-fall safety system, generally consisting of an assembly formed of ropes, slide and carabiner, can be secured to the plate 1 by hooking the carabiner via the orifice 4.
Si nécessaire, la dépose du dispositif d'ancrage ainsi fixé par juxtaposition à la membrure 12 peut s'effectuer en exécutant les opérations inverses à celles décrites ci-dessus et dans un ordre inversé. Après la lecture de ce qui précède, on comprend que la pose et- la dépose du dispositif d'ancrage selon l'invention permet, à l'utilisateur, de gagner un temps appréciable lors de ces opérations et garantit la bonne tenue de l'ancrage à sa fixation. En outre, la conception ergonomique du dispositif selon l'invention qui se trouve fixé par juxtaposition à la membrure, en position oblique par rapport à la verticale et sous les échelons existants ne provoque aucune gêne lors de la montée d'un individu le long de la membrure ni. lors des opérations d'accrochage et de décrochage . If necessary, the removal of the anchoring device thus fixed by juxtaposition to the frame 12 can be carried out by performing the reverse operations to those described above and in reverse order. After reading the above, it is understood that the installation and removal of the anchoring device according to the invention allows the user to save appreciable time during these operations and guarantees the good performance of the anchor to its attachment. In addition, the ergonomic design of the device according to the invention which is fixed by juxtaposition to the frame, in an oblique position relative to the vertical and under the existing rungs does not cause any discomfort during the rise of an individual along the frame nor. during hooking and unhooking operations.
