Abstract
Description
L' invention concerne un dispositif d'ascension le long des supports verticaux et un procédé d'adaptation naturelle et automatique à la forme et aux variations de dimensions du support .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.
Le dispositif respecte la fragilité du support (écorce dans le cas de jeunes arbres, câbles dans le cas de poteaux de Télécommunications ou de Transport de l'Energie.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.
Il existe un nombre important de Brevets, dont beaucoup proviennent de l'U.S Patent, décrivant des dispositifs relatant les solutions étudiées en vue de faciliter l'ascension de l'Homme sur des supports verticaux divers.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.
Nous citerons deux Brevets qui vont nous permettre d'expliquer au-travers des solutions apportées, les différents problèmes non résolus, problèmes qui font que ces inventions n'ont pas eu de débouché commercial.We will cite two Patents which will allow us to explain through the solutions provided, the various unsolved problems, problems which make these inventions have had no commercial outlet.
L'U.S Patent N° 4 137 995 de Frank FONTE décrit ainsi un appareil d'ascension composé de deux plateformes de déplacement alternatif. Un dispositif du type losange peut se déplacer à l'extrémité du cadre et tente d'apporter une solution embryonnaire et très approximative aux problèmes de l'adaptation à la taille et à la forme du support.Frank FONTE's U.S. Patent No. 4,137,995 describes an ascent device made up of two alternative displacement platforms. A diamond-shaped device can move to the end of the frame and attempts to provide an embryonic and very approximate solution to the problems of adaptation to the size and shape of the support.
Les principaux défauts de cet appareil sont :
- non adaptable à toute forme de support,
- non adaptation possible en cours d'ascension à la variation de la taille du support, entrainant au fur et à mesure de l'ascension, un jeu de plus en plus grand entre le ceinturage et le support, donc une position de plus en plus oblique des plateformes par rapport au support, rendant l'usage de cet appareil dangereux au cours de l'élévation, (non rattrapage des variations de diamètre du support),
- ne permet pas la rotation de l'appareil sur le support,
- non respect de la fragilité des supports, de par la forme des surfaces d'appui qui viennent se coincer sur ledit support au moyen de plaques métalliques rigides.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.
Le principal mérite de cet appareil est d'avoir donné le principe d'une ascension alternée à l'aide de deux plateformes de blocage sur le support et dont le principe de base est sécuritif (même si la réalisation décrite ne l'est pas).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) .
L'U.S Patent N° 4 809 815 de Donald R. WALLACE, décrit un appareil manuel d'ascension sur les poteaux.
Ce type d'appareil est très éloigné d'un appareil de type industriel et sécuritif. Néanmoins, il offre le mérite de proposer un dispositif de ceinturage haut et bas de l'arbre ou du poteau, à l'image d'une ceinture tenant un pantalon, donc d'offrir l'idée d'une solution au problème de l'adaptation à la forme du support. Mais la réalisation élémentaire n'offre pas d'intérêt technique.
L'utilisation de cet appareil relève plus de l'acrobatie que de l'appareil de sécurité et est à proscrire.
US Patent No. 4,809,815 to Donald R. WALLACE, describes a manual device for climbing poles.
This type of device is very far from an industrial and secure type of device. Nevertheless, it offers the merit of proposing a device for belting up and down the tree or the post, like a belt holding pants, therefore to offer the idea of a solution to the problem of l adaptation to the shape of the support. But the elementary realization does not offer any technical interest.
The use of this device is more of an acrobatics than a safety device and should be avoided.
D'autres brevets décrivent des dispositifs d'ascension, assez proches des dispositifs précédents. Citons :
- FR-A- 2 627 175 (KOMET ), pratiquement en tous points identiques à celui de F. FONTE,
- DE-C- 3 727 387 (SWOBODA),
- DE-C- 829 107 (A. MUSCHTER),
- U.S.A 1 915 715 (H. BODENDIECK).Other patents describe ascension devices, fairly close to the previous devices. Let us quote:
- FR-A- 2 627 175 (KOMET), practically identical in all respects to that of F. FONTE,
- DE-C- 3 727 387 (SWOBODA),
- DE-C- 829 107 (A. MUSCHTER),
- USA 1 915 715 (H. BODENDIECK).
Aucun de ces brevets n'aborde et à fortiori ne tente de résoudre la délicate et difficile question du rattrapage automatique de diamètre et de l'adaptation naturelle à tout type de support, sans blessure pour ledit support, problème de base à résoudre pour avoir un appareil universel. D'autres problèmes relatifs à l'aspect industriel viennent se greffer.None of these patents addresses and a fortiori attempts to resolve the delicate and difficult question of automatic diameter adjustment and natural adaptation to any type of support, without injury to said support, a basic problem to be solved in order to have a universal device. Other problems relating to the industrial aspect are grafted.
C'est à l'ensemble de ces problèmes non encore résolus, que la présente invention se propose d'apporter des solutions, qui feront de ce dispositif un véritable appareil d'ascension, de type industriel, très sécuritif.It is to all of these unsolved problems that the present invention proposes to provide solutions, which will make this device a real climbing device, industrial type, very safe.
Le problème que nous nous sommes posé peut se résumer ainsi :
- à partir d'un dispositif comportant deux plateformes, la première, en position inférieure, destinée à accueillir les pieds de l'utilisateur lors de sa station verticale, la deuxième servant de plateforme de protection, èventuellement de siège pour le travail, on envisage un dispositif manuel, dont l'utilisation reste à la libre disposition de l'ascensionniste, qui au moyen d'une seule action sur un dispositif adéquat, va permettre l'allongement ou le raccourcissement des dispositifs de ceinturage et simultanément le blocage de la plateforme, en position horizontale, perpendiculairement à l'axe du support, afin d'assurer la sécurité.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.
Par ailleurs les différents dispositifs de blocage et de déblocage des plateformes ne pourront être commandés que dans des conditions précises de fonctionnement : toujours à l'arrêt, jamais en mouvement.In addition, the various locking and unlocking devices of the platforms can only be ordered under precise operating conditions: always stopped, never in motion.
Remarquons que la double intention de s'adapter à la forme du support, et de ne pas blesser ledit support nous oblige à éliminer tous les systèmes de ceinturage rigides (en particulier tous ceux décrits dans les brevets cités), ou ceux dont la texture risque, malgré la souplesse, d'endommager le support. Ainsi, cela revient à éliminer un ceinturage par chaine, ceinturage qui au départ semblait convenir car il alliait la rigidité et une souplesse dans le plan horizontal, en excluant celle du plan vertical. Par analogie, une solution comportant des cables d'acier, réunis par des éclisses, a été testée avec succès,mais ne garantit pas complètement le respect du support.
Si l'on envisage des courroies ou des sangles, le support ne sera pas blessé, mais la tenue horizontale laissera à désirer.Note that the double intention of adapting to the shape of the support, and of not injuring said support obliges us to eliminate all rigid belt systems (in particular all those described in the cited patents), or those whose texture risks , despite the flexibility, to damage the support. Thus, this amounts to eliminating a belt belt, which initially seemed to be suitable because it combined rigidity and flexibility in the horizontal plane, excluding that of the vertical plane. By analogy, a solution comprising steel cables, joined by fishplates, has been successfully tested, but does not completely guarantee compliance with the support.
If you are considering belts or straps, the support will not be injured, but the horizontal holding will leave something to be desired.
C'est pour cela que nous avons opté pour une solution mixte comportant une structure souple et une armature. Nous avons ainsi expérimenté avec succès deux solutions comportant
- la première deux petits cables d'acier, cousus à l'intérieur de deux sangles, sangle d'un type courant utilisé dans les sytèmes de sécurité,
- la deuxième une seule sangle, d'une épaisseur de 2 à 3 mm et de 2cm de largeur, sangle armée par une couche d'élastomère, de type polyuréthane, d'épaisseur variable de 2 à 3 mm.This is why we opted for a mixed solution comprising a flexible structure and a frame. We have thus successfully tested two solutions comprising
- the first two small steel cables, sewn inside two straps, strap of a common type used in safety systems,
- the second a single strap, 2 to 3 mm thick and 2 cm wide, strap reinforced with a layer of elastomer, of polyurethane type, of variable thickness from 2 to 3 mm.
Ainsi, nous avons obtenu, un matériau parfaitement adapté à la solution du double problème posé :
- il est suffisamment souple pour épouser parfaitement tout type de support,
- il offre une bonne tenue dans le plan horizontal, tenue nécessaire pour glisser le long du support en cours d'ascension.Thus, we obtained, a material perfectly adapted to the solution of the double problem posed:
- it is flexible enough to perfectly fit any type of support,
- it offers good hold in the horizontal plane, hold necessary to slide along the support during ascent.
Remarquons, que l'on aurait pu remplacer , dans la première solution les câbles d'acier par des cables en Kevlar ou en tout autre textile de très haute résistance, mais la tenue verticale en serait amoindrie.It should be noted that, in the first solution, the steel cables could have been replaced by cables made of Kevlar or any other very high-strength textile, but the vertical hold would be lessened.
Une autre solution aurait pu consister à utiliser des courroies dites synchrones, car elles comportent en interne des fils de Kevlar ( ou autres) de renforcement qui leur confèrent une solidité sans égale.Another solution could have been to use so-called synchronous belts, because they have internal Kevlar (or other) reinforcing threads which give them unequaled solidity.
Nous avons préféré la solution de sangle armée par un élastomère.We preferred the strap solution armed with an elastomer.
La Fig. 1 montre l'appareil et les différents parcours des ceinturages, comme ce sera explicité par la suite.
Le ceinturage du bas ne peut être assuré par le même dispositif car les sangles devant se déplacer à l'intérieur des tubes arrondis ne pourront le faire aisément. Dans ce cas, nous avons opté, pour une solution mixte comportant une courte surface d'appui constituée d'une sangle armée prolongée par une corde armée, corde permettant le glissement facile à l'intérieur de l'armature arrondie.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. In this case, 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.
Dans le cas d'une utilisation ou la fragilité du support est primordiale, on pourra toujours habiller le dispositif à sangles avec un manchon de caoutchouc protecteur amovible.In the case of use or the fragility of the support is essential, we can always cover the strap device with a removable protective rubber sleeve.
Description d'une plateforme.Description of a platform.
Chaque plateforme est constituée selon la Fig.1:
- de deux montants latéraux, selon une forme ovoïde (5) analogue à celle d'une luge .
- des dispositifs de ceinturage haut et bas,
- des dispositifs pour les pieds et pour s'asseoir.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.
Chaque plateforme doit permettre :
- l'adaptation naturelle à la forme du support, sans l'abimer. Par son principe, elle améliore beaucoup la fixation de la plateforme sur le support en faisant corps avec celui-ci,
- l'allongement et le raccourcissement permanent des dispositifs de ceinturage (Fig.3), en cours d'ascension ou en cours de descente , afin que la plateforme soit constamment perpendiculaire à l'axe du support, conférant une stabilité horizontale permanente à l'ensemble plateforme + Homme, indépendamment de la variation de diamètre support, puisque désormais il n'y a plus de jeu entre le ceinturage et le support.
- un blocage naturel et automatique assurant la plus grande sécurité afin que tout déverrouillage intempestif soit interdit durant l'ascension, ou la descente, ou lorsque la plateforme est positionnée.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.
La position de la plateforme ne peut être modifiée :
. qu'en prenant appui complet sur l'autre plateforme.
. qu'en actionnant le système de verrouillage et, simultanément, en tirant celle-ci en arrière, ce qui exclut naturellement toute fausse manoeuvre, ou tout décrochage, lorsque l'utilisateur est en position de travail, puisque le poids de l'utilisateur ne fait que renforcer l'effet de coincement de la plateforme sur le support.
D'autre part, si l'ascensionniste est sur la plateforme, il ne pourra tirer celle-ci en arrière.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.
Principe de fonctionnement d'une plateforme.(Fig. 1):Principle of operation of a platform (Fig. 1):
L'utilisateur dépose la 1e plateforme au pied du support, ( arbre, mât, poteau,...) ouvre le verrou (9) de jonction de la sangle supérieure (1) et entoure le support avec la sangle armée, puis referme le verrou d'accrochage de la sangle.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.
On peut alors faire circuler (ou glisser) verticalement la plateforme le long du support vertical, puisque l'on a pris la précaution de laisser un jeu permettant de dégager la plateforme du support.We can then circulate (or slide) vertically the platform along the vertical support, since we have taken the precaution to leave a clearance allowing to release the platform from the support.
Puis la plateforme étant positionnée à hauteur, l'opérateur actionne le ou les verrous latéraux de blocage des crémaillères (8) En s'ouvrant, le tenon de retenue (15) libère la crémaillère, retenue par un élastique du type sandow (12) attaché à un point fixe (11). La crémaillère amorce un recul stoppé lorsque le double demi-ceinturage haut (1) et bas (3) épouse très exactement la forme du support (Fig. 3 et 4), ainsi que les montants latéraux ovoïdes (5).Then the platform being positioned at height, the operator actuates the lateral rack locking bolt (s) (8). By opening, 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).
L'utilisateur peut alors relâcher le verrou (17) et le tenon de blocage de la crémaillère (15) vient alors se positionner dans un des crans de la crémaillère (2), bloquant ainsi tout l'ensemble mobile et assurant la sécurité recherchée.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.
Un ressort (13) maintient tiré vers le bas, le corps du verrou, celui-ci pivotant autour de son axe (18). Pour échapper la crémaillère, le tenon (15) vient se loger en (14)A spring (13) keeps the body of the lock pulled down, the latter pivoting about its axis (18). To escape the rack, the tenon (15) is housed in (14)
Remarquons bien que ce n'est pas l'élastique qui tient la crémaillère en position, mais l'ensemble crémaillère (2), tenon (15) et ressort (13).Note that it is not the elastic that holds the rack in position, but the rack assembly (2), lug (15) and spring (13).
On note le double mouvement :
- celui de la sangle armée en position haute (1) de la plateforme, et celui de la corde armée (3), associée, correspondant au ceinturage diamétralement opposé , mais en position basse.
- celui des deux montants (5) qui se rapprochent jusqu'à venir sensiblement au contact avec le support (28 et 29), améliorant ainsi la tenue de l'ensemble de la plateforme avec le support, puisque celle-ci fait désormais corps avec celui-ci.We note the double movement:
- that of the reinforced strap in the high position (1) of the platform, and that of the reinforced rope (3), associated, corresponding to the diametrically opposite belt, but in the low position.
- that of the two uprights (5) which come together until they come substantially into contact with the support (28 and 29), thereby improving the hold of the whole platform with the support, since the latter is now integral with this one.
L'ensemble de la plateforme (5), de la ceinture (sangles et corde armées 1 et 3) et montants latéraux (5) participent activement à l'effort de tenue de la plateforme sur ledit support.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.
A l'opposé lorsque l'ascension s'est produite, et en cas de variation de diamètre, l'opérateur doit débloquer la plateforme de sa position bloquée sur le support. Il appuie sur le verrou (17) de blocage de la crémaillère, en même temps, il tire en arrière sur les montants (5) de la plateforme pour ramener les crémaillères vers l'avant, afin de donner du mou au ceinturage haut et bas. Cela revient à décaler légèrement vers l'avant l'axe de la plateforme vis-à-vis de l'axe du support vertical, donc à agrandir la circonférence de la ceinture par rapport à celle du support. Les deux montants ovoïdes (5) de la plateforme, s'ils sont sollicités en ce sens par l'opérateur vont donc s'écarter latéralement selon les directions (24 et 25).Conversely, when the ascent has occurred, and in the event of a variation in diameter, the operator must unlock the platform from its locked position on the support. He presses on the rack locking bolt (17), at the same time, he pulls back on the uprights (5) of the platform to bring the racks forward, in order to give slack to the top and bottom belts . This amounts to shifting slightly the axis of the platform towards the axis of the vertical support, thus enlarging the circumference of the belt relative to that of the support. The two ovoid uprights (5) of the platform, if they are urged in this direction by the operator will therefore deviate laterally in the directions (24 and 25).
Ceci montre la parfaite réalisation de l'objectif fixé :
le rattrapage automatique ( par libération voulue du verrou (17) et du tenon (15) aux variations de diamètre du support et l'adaptation naturelle à la forme et à la dimension du support.This shows the perfect achievement of the objective set:
automatic take-up (by desired release of the latch (17) and the tenon (15) to variations in the diameter of the support and the natural adaptation to the shape and size of the support.
On constate que l'appareil restant constamment en contact étroit avec le support, l'axe du support (01-02) reste le même quelles que soient les variations de diamètre de celui-ci, la plateforme reste horizontale et sensiblement perpendiculaire au support, ce qui conduit à une position de travail parfaitement sécuritive, sécurité qui ne dépend pas du diamètre, de la forme du support, ou de la hauteur de la plateforme sur le support.It can be seen that 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.
- La Fig. 1 montre l'appareil en position sur un support. On distingue les deux plateformes (6 et 7), les montants ovoïdes (5) avec les crémaillères de rattrapage de diamètre (2), les verrous de blocage (8), les ceintures haute (1) et basse(3), ainsi que les parties socle (6) et siège (7). Le verrou (9) assure la jonction des deux parties de la ceinture haute (1).Fig. 1 shows the device in position on a support. We can distinguish the two platforms (6 and 7), the ovoid uprights (5) with the diameter take-up racks (2), the locking latches (8), the high (1) and low (3) belts, as well as the base (6) and seat (7) parts. The latch (9) joins the two parts of the upper belt (1).

La Fig. 2 montre une vue de trois quarts avant afin de préciser quel est le trajet des différentes parties destinées au ceinturage du support, et notamment l'entrée (21) de la ceinture basse dans l'arrondi des montants ovoïdes (5).
La crémaillère (2) est maintenue par le tenon (19) de retenue du verrou, la poignée de libération du verrou (17) avec son axe de rotation (18) son ressort de rappel (13), et l'axe d'accrochage du ressort (19).
L'arrière de la crémaillère est attaché en (16) à un cable élastique (12), cable lui-même relié en un point fixe (11).Fig. 2 shows a three-quarter front view in order to specify what is the path of the various parts intended for the belt of the support, and in particular the entry (21) of the low belt in the rounding of the ovoid uprights (5).
The rack (2) is held by the latch retainer (19), the latch release handle (17) with its axis of rotation (18) its return spring (13), and the latching axis of the spring (19).
The rear of the rack is attached at (16) to an elastic cable (12), the cable itself connected at a fixed point (11). - Les Fig. 3 et 4 montrent un schéma d'adaptation de l'appareil à différents diamètres de support, ainsi que la position de la pièce de jonction (23) des deux montants ovoïdes (5), qui permet aux montants latéraux de se rapprocher ou de s'éloigner du support.Figs. 3 and 4 show a diagram of adaptation of the device to different support diameters, as well as the position of the junction piece (23) of the two ovoid uprights (5), which allows the lateral uprights to approach or to s '' move away from the support.
Les Fig. 3 et 4 montrent la position des crémaillères à l'intérieur des montants selon le diamètre du support et le sens de déplacement des différentes parties de l'appareil lors d'une opération de rattrapage de diamètre.
On note également que les centres 01 et 02 restent confondus et que les côtés (5) de l'appareil restent tangents aux différents cercles en (28 et 29).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.
We also note that the
Les deux cotés (5) pivotent sur des pivots (22), fixation d'un dispositif (23) de solidarisation des montants latéraux. En retirant un des pivots (22), et en retirant le socle ou le siège, les deux montants peuvent se replier l'un contre l'autre autorisant le transport de l'appareil sans difficulté.The two sides (5) pivot on pivots (22), fixing of a device (23) for securing the lateral uprights. By removing one of the pivots (22), and by removing the base or the seat, the two uprights can be folded against each other allowing the transport of the device without difficulty.
Claims (3)
- par l'adaptation naturelle à la forme du support par choix d'une ceinture haute (1) en forme de demi-circonférence externe au support, constituée d'une sangle armée d'une couche d'élastomère, de même épaisseur,
- par le choix d'une ceinture basse, en forme de demi-circonférence interne (3), constituée également d'une sangle recouverte d'une couche d'élastomère et prolongée de part et d'autre par une corde armée d'un cable d'acier, afin d'épouser au mieux la partie arrondie des montants ovoïdes (5) et se rattachant avec la ceinture haute (1) au niveau du verrou (9),
- par un procédé de rattrapage automatique des variations de diamètre du support, au moyen des deux ceintures haute et basse précédentes et d'un dispositif verrou fixe (8) et crémaillère mobile (2), fixé sur chacun des montants (5) et destiné à adapter les ceinturages haut et bas au diamètre du support, lors d'une action de l'opérateur sur la poignée (17) du verrou.1- Climbing device on all types of vertical supports, composed of two horizontal platforms (6 and 7) supported by lateral uprights (5) characterized:
- by natural adaptation to the shape of the support by choosing a high belt (1) in the form of a semi-circumference external to the support, consisting of a strap reinforced with a layer of elastomer, of the same thickness,
- by the choice of a low belt, in the form of an internal half-circumference (3), also consisting of a strap covered with a layer of elastomer and extended on both sides by a cord armed with a steel cable, in order to best fit the rounded part of the ovoid uprights (5) and connected with the high belt (1) at the bolt (9),
- by an automatic process for taking up variations in the diameter of the support, by means of the two previous high and low belts and a fixed lock device (8) and movable rack (2), fixed on each of the uprights (5) and intended to adapt the top and bottom belts to the diameter of the support, during an action of the operator on the handle (17) of the lock.
En s'écartant, les montants (5) pivotent autour des pivots (22) de la traverse (23) joignant les deux cotés de l'appareil. L'extrémité (28) des montants reste en étroit contact avec le support vertical, contribuant ainsi à améliorer la stabilité générale de l'ensemble.
Un des pivots (22) de la barre de jonction (23) peut être retiré afin de replier l'appareil sur lui-même.3- Device according to claim 1 characterized in that the rack (2) movable back and forth inside the upper horizontal upright on one side of the device (5), is connected to an elastic cable ( 12) by means of a fixing (16). This elastic cable is attached to a fixed point (11) of the lower lateral upright: it tends to pull the rack back. The other end of the rack is attached to the two upper and lower belts (1 and 3); the rack will pull on them and force them to close as much as possible on the vertical support, and thus tend towards the minimum diameter, on the express condition that the operator actuates the handle (17) of the lock (8). To do this, the operator must lift the platform in order to disengage the belts from the support: by pulling back on the side pillars (5), and keeping the latches lowered (17) he can increase the diameter of the support's belt ( 26 and 27). The uprights (5) can deviate in the directions (24 and 25), but the centers 01 and 02 (Fig. 4) remain combined: the axis of the support therefore remains the same and is independent of variations in diameter of the support .
By moving away, the uprights (5) pivot around the pivots (22) of the crosspiece (23) joining the two sides of the device. The end (28) of the uprights remains in close contact with the vertical support, thereby helping to improve the overall stability of the assembly.
One of the pivots (22) of the junction bar (23) can be removed in order to fold the device back on itself.
