Description

La présente invention concerne un procédé de déploiement d'un chasse pieds pour ascenseur, un chasse pieds, un compas pour leur mise en oeuvre et ses applications.The present invention relates to a method of deploying an elevator foot fighter, a hunt feet, a compass for their implementation and its applications.

La construction et l'installation des ascenseurs pour bâtiments existants sont l'objet de règles de sécurité. La norme française XP/P/82-511 et 611 d'avril 1999 impose la présence d'un dispositif de protection d'au moins 750 mm de hauteur installé sous la cabine d'ascenseur afin d'interdire l'accès à l'espace situé directement en dessous de ladite cabine. Ce dispositif comprenant au moins un panneau de la largeur d'une porte palière et protégeant sur la hauteur précitée est appelé chasse pieds. Il protège en effet les pieds des utilisateurs lorsque la cabine ne s'arrête pas exactement au niveau d'un palier. Si le décalage est important, ce dispositif protège d'une chute dans la cage de l'ascenseur.The construction and installation of lifts for existing buildings is subject to safety regulations. The French standard XP / P / 82-511 and 611 of April 1999 imposes the presence of a protective device of at least 750 mm height installed under the elevator car in order to prevent access to the space located directly below said cabin. This device comprising at least one panel the width of a landing door and protecting the above height is called hunt feet. It protects the feet of users when the cabin does not stop exactly at a level. If the offset is important, this device protects from a fall in the elevator shaft.

Si l'installation de tels dispositifs est relativement aisée dans les nouvelles installations, puisqu'il suffit de concevoir un fond de cage d'ascenseur suffisamment profond, la rénovation crée des problèmes, notamment dans le cas de fonds de cage d'ascenseur peu profonds. En effet, dans les bâtiments existants, le fond de cage est souvent insuffisant pour contenir toute la hauteur du dispositif de protection lorsque la cabine d'ascenseur est dans au niveau le plus inférieur.If the installation of such devices is relatively easy in the new facilities, since it is sufficient to design a bottom of elevator shaft deep enough, the renovation creates problems, especially in the case of shallow elevator shaft funds . Indeed, in existing buildings, the bottom of the cage is often insufficient to contain the entire height of the protective device when the elevator car is in the lowest level.

EP 1854758 (A1) décrit un tablier chasse pieds en trois parties télescopiques pour une cabine d'ascenseur, qui comporte trois sections télescopiques substantiellement en forme de plaque. Le tablier a un dispositif manuel de blocage, un dispositif manuel de déverrouillage et un amortisseur pour freiner le mouvement d'une position rétractée vers une position déployée. En position rétractée, deux sections du tablier chevauchent la section de base. EP 1854758 (A1) discloses a three-part telescopic leg flushing apron for an elevator car, which has three substantially plate-like telescopic sections. The apron has a manual locking device, a manual unlocking device and a damper for braking the movement from a retracted position to an extended position. In the retracted position, two sections of the deck overlap the base section.

Il serait donc souhaitable de disposer d'un chasse pieds comprenant plusieurs panneaux télescopiques ou même mieux, également escamotables. Un tel chasse pieds devrait pouvoir se déployer en position active, de préférence lentement pour éviter les chocs, pouvoir se bloquer en position active et résister à une poussée radiale (perpendiculaire à la direction de déplacement de l'ascenseur.It would therefore be desirable to have a hunt feet comprising several telescopic panels or even better, also retractable. Such a hunt should be able to deploy in position active, preferably slowly to avoid shocks, able to lock in the active position and resist a radial thrust (perpendicular to the direction of movement of the elevator.

Or après de longues recherches insatisfaisantes, la demanderesse a mis au point un procédé de déploiement d'un dispositif de protection et un dispositif de protection donnant satisfaction, fondés sur un compas d'articulation muni d'une pièce multifonctionnelle de conception originale. Les problèmes rencontrés ont notamment été les suivants:

  • imaginer une procédure simple , sure et efficace tant d'ouverture que de fermeture d'un chasse-pieds et à cette fin imaginer un pocédé basculant et un dispositif originaux,
  • limiter la vitesse d'ouverture en basculement, compte tenu du poids des pièces,
  • retenir les panneaux lors du basculement
  • autoriser le déploiement des panneaux à la fin du basculement
  • verrouiller les compas (ou jambes de force) lors du repliage de l'ensemble.
But after long unsatisfactory research, the applicant has developed a method of deployment of a protective device and a protective device satisfactory, based on a hinge compass equipped with a multifunctional piece of original design. The problems encountered included the following:
  • imagine a simple, safe and effective procedure for both opening and closing a footplate and to this end imagine a rocking process and an original device,
  • limit the speed of opening when tipping, given the weight of the parts,
  • hold the panels when tilting
  • allow panels to deploy at the end of failover
  • lock the compasses (or struts) when folding the assembly.

C'est pourquoi la présente demande a pour objet un procédé de déploiement d'un chasse pieds comprenant deux, trois ou quatre panneaux télescopiques coulissants dont un panneau proximal et un panneau distal, le panneau proximal étant fixé pivotant sous une cabine d'ascenseur et étant solidairement muni d'un compas limitant le pivotement pour que les panneaux télescopiques coulissants soient environ verticaux lorsque le compas est déployé, le panneau distal en position déployée étant éloigné de la cabine d'ascenseur, et les panneaux étant initialement placés environ parallèlement au plancher de la cabine d'ascenseur et verrouillés en cette position, dans lequel

  • on déverrouille les panneaux, ce qui provoque leur pivotement vers une position verticale et l'ouverture du compas,
  • le compas étant muni d'une pièce multifonctionnelle prévue vers l'extrémité distale du compas, ladite pièce multifonctionnelle comprenant deux saillies dirigées vers l'intérieur des plaques, l'une de repliement et l'autre de blocage, la saillie de blocage bloquant initialement le déploiement du panneau distal, les saillies étant de préférence longitudinalement décalées l'une par rapport à l'autre vis-à-vis du compas,
  • l'ouverture du compas produisant la rotation de la pièce multifonctionnelle et de la saillie de blocage et en conséquence le déblocage d'un élément du panneau distal, autorisant ainsi le déploiement environ vertical dudit panneau distal et en conséquence du ou des panneaux intermédiaires optionnels,
  • et en ce que le panneau distal entraine vers le bas le ou les panneaux intermédiaires optionnels.
That is why the present application relates to a method of deploying a hunt comprising two, three or four sliding telescopic panels including a proximal panel and a distal panel, the proximal panel being pivotally fixed under an elevator car and being integrally provided with a compass limiting the pivoting so that the sliding telescopic panels are approximately vertical when the compass is deployed, the distal panel in the extended position being remote from the elevator car, and the panels being initially placed approximately parallel to the floor of the elevator car and locked in this position, in which
  • the panels are unlocked, which causes them to pivot towards a vertical position and the opening of the compass,
  • the compass being provided with a multifunctional piece provided towards the distal end of the compass, said multifunctional part comprising two projections directed towards the inside of the plates, one of folding and the other of locking, the blocking projection initially blocking the deployment of the distal panel, the projections being preferably longitudinally offset relative to each other vis-à-vis the compass,
  • the opening of the compass producing the rotation of the multifunctional part and the blocking projection and consequently the unlocking of an element of the distal panel, thereby permitting the vertical expansion of said distal panel and consequently of the optional intermediate panel or panels,
  • and in that the distal panel drives down the optional intermediate panel (s).

Les saillies peuvent être longitudinalement superposées mais elles sont de préférence décalées l'une par rapport à l'autre vis-à-vis de la longueur du compas Ainsi l'une peut être qualifiée de "distale" et l'autre de "proximale".The projections may be longitudinally superimposed but they are preferably offset relative to each other vis-à-vis the length of the compass So one can be described as "distal" and the other "proximal" .

Un chasse pieds mis en oeuvre dans l'invention comprend deux, trois ou quatre mais de préférence deux ou trois, particulièrement trois panneaux télescopiques coulissants. Un nombre plus élevé de panneaux télescopiques coulissants est techniquement possible mais alourdit et rend inutilement plus complexe le chasse pieds de l'invention.A hunt feet implemented in the invention comprises two, three or four but preferably two or three, particularly three sliding telescopic panels. A higher number of sliding telescopic panels is technically possible but weighs down and unnecessarily complicates the hunt of the invention.

La hauteur déployée des panneaux peut aller de 1,5 à 0,3, de préférence de 1,0 à 0,4, notamment de 0,8 à 0,4, tout particulièrement de 0,75 à 0,55 mètre.The unfolded height of the panels can range from 1.5 to 0.3, preferably from 1.0 to 0.4, especially from 0.8 to 0.4, especially from 0.75 to 0.55 meters.

La hauteur de chaque panneau peut aller de 0,75 à 0,10 , de préférence de 0,60 à 0,15 , notamment de 0,4 à 0,25 , tout particulièrement de 0,30 à 0,25 mètre.The height of each panel may range from 0.75 to 0.10, preferably from 0.60 to 0.15, in particular from 0.4 to 0.25, more particularly from 0.30 to 0.25 meter.

Le panneau proximal est fixé pivotant sous une cabine d'ascenseur. Il peut y être directement fixé, mais dans des conditions préférentielles de mise en oeuvre de l'invention, le panneau proximal est indirectement fixé à la cabine par un coffrage qui est lui-même fixé à la cabine.The proximal panel is pivotally attached under an elevator car. It can be directly attached to it, but under preferential conditions of implementation of the invention, the proximal panel is indirectly fixed to the cabin by a formwork which is itself fixed to the cabin.

L'axe de pivotement du panneau proximal est avantageusement prévu environ parallèlement au plancher de la cabine d'ascenseur.The pivot axis of the proximal panel is advantageously provided approximately parallel to the floor of the elevator car.

Le côté proximal du compas est fixé par pivot au coffrage ou à la cabine d'ascenseur et du côté distal de préférence à proximité du côté distal du panneau proximal.The proximal side of the compass is pivotally attached to the elevator casing or car and distal side preferably near the distal side of the proximal panel.

Les panneaux sont initialement placés environ parallèlement au plancher de la cabine d'ascenseur et verrouillés en cette position. Par "environ parallèlement" on entend ici que les panneaux forment un angle pouvant aller de - 30 ° à + 30 °, avantageusement de - 20 ° à + 20 °, de préférence de - 10 ° à + 10°, notamment sont horizontaux.The panels are initially placed approximately parallel to the floor of the elevator car and locked in this position. By "approximately parallel" is meant here that the panels form an angle ranging from -30 ° to + 30 °, preferably from -20 ° to + 20 °, preferably from -10 ° to + 10 °, in particular are horizontal.

Dans des conditions préférentielles de mise en oeuvre du procédé ci-dessus décrit, le panneau distal ou un panneau intermédiaire appuie sur la saillie de blocage du compas pour le bloquer en position ouverte.Under preferred conditions of implementation of the method described above, the distal panel or an intermediate panel presses on the locking projection of the compass to lock it in the open position.

La présente demande a aussi pour objet un procédé de repliement d'un chasse pieds ci-dessus, notamment après déploiement comme ci-dessus, caractérisé en ce que

  • on provoque la remontée du panneau distal
  • une partie du panneau distal venant alors appuyer sur la saillie de repliement de la pièce multifonctionnelle ce qui provoque son pivotement et en conséquence le déblocage du compas, ce qui autorise le pivotement vertical des panneaux
  • la saillie de blocage de la pièce multifonctionnelle pivotant également et venant bloquer le panneau distal en position repliée.
  • on provoque le pivotement des panneaux pour les replier en position environ horizontale.
The present application also relates to a method of folding a hunt feet above, especially after deployment as above, characterized in that
  • it causes the raising of the distal panel
  • a part of the distal panel then pressing on the folding projection of the multifunctional part which causes its pivoting and consequently the release of the compass, which allows the vertical pivoting of the panels
  • the locking projection of the multifunctional piece pivoting as well and coming to block the distal panel in the folded position.
  • the panels are pivoted to fold them in approximately horizontal position.

Dans des conditions préférentielles de mise en oeuvre du procédé ci-dessus décrit, la remontée du panneau distal entraine la remontée du ou des panneaux intermédiaires optionnels.Under preferred conditions of implementation of the method described above, the rise of the distal panel causes the rise of the optional intermediate panels.

La présente demande a aussi pour objet, notamment pour la mise en oeuvre du procédé ci-dessus décrit, un chasse pieds comprenant deux, trois ou quatre panneaux télescopiques coulissants dont un panneau proximal et un panneau distal, le panneau proximal étant en position déployée celui qui est le plus proche du palier d'ascenseur et étant prévu pivotant sous une cabine d'ascenseur et étant aussi solidairement muni d'un compas limitant le pivotement des panneaux télescopiques coulissants pour que lesdits panneaux télescopiques coulissants soient environ verticaux en position déployée, le panneau distal étant en position déployée celui qui est le plus éloigné du palier d'ascenseur, et les panneaux étant initialement placés environ parallèlement au plancher de la cabine d'ascenseur et verrouillés en cette position, caractérisé en ce que le compas est muni d'une pièce multifonctionnelle solidairement prévue vers l'extrémité distale du compas, ladite pièce multifonctionnelle comprenant deux saillies dirigées vers l'intérieur des plaques, les saillies étant de préférence longitudinalement décalées vis-à-vis du compas, le panneau distal comprenant un organe coopérant avec la saillie de blocage bloquant le panneau distal avant déploiement et après repliement lorsque le panneau distal arrive en butée, le panneau distal comprenant aussi une langue formant butée coopérant avec la saillie de repliement de la pièce multifonctionnelle pour la pousser en fin de course de repliement dudit panneau distal et provoquer le déblocage du compas et son début de fermeture.The present application also relates, in particular to the implementation of the method described above, a flush comprising two, three or four sliding telescopic panels including a proximal panel and a distal panel, the proximal panel being in the deployed position the which is the closest to the elevator landing and being provided to pivot under an elevator car and also being integrally provided with a compass limiting the pivoting of the sliding telescopic panels so that said sliding telescopic panels are approximately vertical in the deployed position, the distal panel being in the deployed position which is furthest from the elevator landing, and the panels being initially placed approximately parallel to the floor of the elevator car and locked in this position, characterized in that the compass is provided with a multifunctional part integrally provided towards the distal end of the compass, said multi piece functional assembly comprising two projections directed towards the inside of the plates, the projections preferably being longitudinally offset with respect to the compass, the distal panel comprising a member cooperating with the locking projection blocking the distal panel before deployment and after folding when the distal panel comes into abutment, the distal panel also comprising a tongue forming a stop cooperating with the projection of folding of the multifunctional part to push it at the end of folding course of said distal panel and cause the release of the compass and its beginning of closure.

Les panneaux télescopiques coulissants sont avantageusement montés sur glissières.The sliding telescopic panels are advantageously mounted on slides.

Dans des conditions préférentielles de mise en oeuvre de l'invention, le chasse pieds ci-dessus comprend en outre un câble de traction fixé au panneau distal pour replier l'ensemble du dispositif, accessible depuis la palier. Le câble de traction est avantageusement rangé dans un enrouleur automatique par exemple à ressort, fixé au panneau distal.Under preferential conditions of implementation of the invention, the hoof feet above further comprises a traction cable attached to the distal panel to fold the entire device, accessible from the bearing. The traction cable is advantageously stored in an automatic winder, for example a spring, fixed to the distal panel.

Dans encore d'autres conditions préférentielles de mise en oeuvre de l'invention, le chasse pieds ci-dessus renferme en outre un amortisseur installé entre le panneau distal et le panneau proximal, avantageusement deux amortisseurs, lorsque le chasse pieds comprend seulement un panneau distal et un panneau proximal. Un amortisseur freine la descente du ou des panneaux télescopiques autres que le panneau proximal qui est fixe en translation.In still other preferred conditions of implementation of the invention, the hunt feet above also contains a damper installed between the distal panel and the proximal panel, preferably two dampers, when the flush includes only a distal panel and a proximal panel. A damper brakes the descent of the telescopic panel or panels other than the proximal panel which is fixed in translation.

Le ou les amortisseurs installés entre le panneau distal et le panneau intermédiaire travaillent en poussée ou en retenue, avantageusement ce dernier.Preferably, the shock absorber (s) installed between the proximal panel and the distal panel work in thrust. In the presence of an intermediate panel, or dampers installed between the proximal panel and the intermediate panel advantageously work in thrust. The shock absorber (s) installed between the distal panel and the intermediate panel work in thrust or restraint, advantageously the latter.

Dans encore d'autres conditions préférentielles de mise en oeuvre de l'invention, le dispositif comprend en outre un vérin, avantageusement deux vérins, pour ralentir le basculement des panneaux vers le bas lors de l'ouverture. Ceux-ci sont de préférence installés entre une partie, avantageusement distale, du panneau proximal et un point d'attache directe ou indirecte (coffrage par exemple) sur une cabine d'ascenseur.In still other preferred conditions of implementation of the invention, the device further comprises a jack, preferably two cylinders, to slow the tilting of the panels down during opening. These are preferably installed between a portion, preferably distal, of the proximal panel and a direct or indirect attachment point (formwork for example) on an elevator car.

Dans toujours d'autres conditions préférentielles de mise en oeuvre de l'invention, le chasse pieds ci-dessus est installé dans un coffrage. Ainsi, on peut directement installer le coffrage avec le chasse pieds sous une cabine d'ascenseur. En un nombre limité d'opérations.In still other preferred conditions of implementation of the invention, the hunt feet above is installed in a formwork. So, we can directly install the formwork with the hunt feet under an elevator car. In a limited number of operations.

Le compas étant un compas d'articulation, chacune de ses extrémités est montée sur un pivot, du côté distal à un panneau proximal, du côté distal à une cabine d'ascenseur ou de préférence à un coffrage de rangement du dispositif. Le pivot peut ainsi se déplier pour déterminer l'ouverture maximale des panneaux, et se replier pour rangement des panneaux vers l'horizontale.The compass being a hinge compass, each of its ends is mounted on a pivot, the distal side to a proximal panel, the distal side to an elevator car or preferably to a storage form of the device. The pivot can unfold to determine the maximum opening of the panels, and fold for storage panels horizontally.

Dans encore d'autres conditions préférentielles de mise en oeuvre de l'invention, un ensemble de butées prévues sur les panneaux détermine des positions extrêmes de déploiement et de repliement des chasse pieds de l'invention.In still other preferred conditions of implementation of the invention, a set of stops provided on the panels determines extreme positions of deployment and folding hunt feet of the invention.

Un chasse pieds préféré de l'invention comprend un amortisseur coopérant avec une élingue de traction solidaire du panneau proximal pour ralentir l'ouverture en basculement des panneaux télescopiques coulissants.A preferred flush of the invention comprises a damper cooperating with a traction sling integral with the proximal panel to slow down the tilting opening of the sliding telescopic panels.

Un autre chasse pieds préféré de l'invention comprend un système de verrouillage en position repliée associé à un contact électrique signalant ladite position repliée.Another preferred flush of the invention comprises a locking system in the folded position associated with an electrical contact signaling said folded position.

Dans encore d'autres conditions préférentielles de mise en oeuvre de l'invention, un chasse pieds de l'invention comprend un bras articulé associé à un ou plusieurs contacts signalant la position déployée dudit chasse pieds, ledit bras articulé étant d'un côté solidaire du panneau proximal et de l'autre du panneau distal.In still other preferred conditions of implementation of the invention, a hunt feet of the invention comprises an articulated arm associated with one or more contacts signaling the extended position of said hunt feet, said hinged arm being on one side solidarity of the proximal panel and the other of the distal panel.

Les pièces travaillant le plus durement du chasse pieds de l'invention sont avantageusement réalisées en acier. Certaines pièces travaillant durement, à fins d'allègement peuvent aussi être réalisées en aluminium ou alliage d'aluminium comme les panneaux, notamment distal ou intermédiaire(s) optionnel(s).The parts working the hardest hunt feet of the invention are advantageously made of steel. Some parts working hard for lightening purposes can also be made of aluminum or aluminum alloy such as panels, including distal or intermediate (s) optional (s).

A noter que dans la présente demande, classiquement l'article indéfini "un" doit être considéré comme un pluriel générique (signification de "au moins un" ou encore "un ou plusieurs"), sauf lorsque le contexte montre le contraire (1 ou "un seul"). Ainsi, par exemple, lorsque l'on dit ci-dessus que l'on prévoit un compas, il s'agit d'un ou plusieurs compas notamment deux compas, l'un à gauche, l'autre à droite du chasse pieds.Note that in the present application, conventionally the indefinite article "a" must be considered as a generic plural (meaning "at least one" or "one or more"), except when the context shows the opposite (1 or "only one"). Thus, for example, when it is said above that a compass is provided, it is one or more compasses including two compasses, one on the left, the other on the right of the hunt feet.

L'homme de l'art appréciera que le compas particulier décrit ci-dessus est un élément important du procédé et du dispositif et a été conçu pour leur mise en oeuvre. Il permet les fonctions suivantes en commençant par la position où les panneaux sont rangés:

  • position pliée ou partiellement pliée du compas: blocage de la translation du panneau distal grâce à la saillie de blocage de la pièce multifonctionnelle en faisant obstacle à un téton dudit panneau distal,
  • position ouverte du compas: libération de la translation du panneau distal par dégagement du téton dudit panneau distal,
  • position ouverte du compas: détermination de la position d'ouverture maximale des panneaux et blocage des panneaux dans cette position,
  • position ouverte du compas: blocage de la descente d'un panneau intermédiaire et blocage des panneaux dans cette position en maintenant le compas en position ouverte par pression sur la saillie de repliement de la pièce multifonctionnelle,
  • position remontée ou partiellement remontée du compas: déblocage et fermeture du compas par pression des langues formant butée prévues latéralement sur le côté distal du panneau distal,
  • position pliée ou partiellement pliée du compas: blocage avant fermeture de la translation du panneau distal grâce à la saillie de blocage de la pièce multifonctionnelle en faisant obstacle à un téton dudit panneau distal.
It will be appreciated by those skilled in the art that the particular compass described above is an important part of the method and device and has been designed for their implementation. It allows the following functions starting from the position where the panels are stored:
  • folded or partially folded position of the compass: blocking the translation of the distal panel by virtue of the locking projection of the multifunctional part by preventing a nipple of said distal panel,
  • open position of the compass: release of the translation of the distal panel by disengaging the nipple of said distal panel,
  • open position of the compass: determination of the maximum open position of the panels and blocking of the panels in this position,
  • open position of the compass: blocking the descent of an intermediate panel and blocking the panels in this position by keeping the compass in the open position by pressing on the folding projection of the multifunctional part,
  • raised or partially raised position of the compass: release and closure of the compass by pressing the tongues forming a stop provided laterally on the distal side of the distal panel,
  • folded or partially folded position of the compass: locking before closure of the translation of the distal panel through the locking projection of the multifunctional part by obstructing a nipple of said distal panel.

C'est pourquoi la présente demande a enfin pour objet un compas comportant deux branches et deux extrémités, comprenant solidairement à l'une de ses extrémités une pièce multifonctionnelle installée du côté interne de fermeture du compas, ladite pièce comprenant deux saillies installées avantageusement consécutivement dans la direction longitudinale du compas, les extrémités du compas étant agencées pour pivoter. Les extrémités du compas sont avantageusement alésées en accord avec le pivot de ses deux branches.This is why the present application finally relates to a compass comprising two branches and two ends, comprising integrally at one of its ends a multifunctional part installed on the inner side of the compass closure, said part comprising two projections advantageously installed consecutively in the longitudinal direction of the compass, the ends of the compass being arranged to rotate. The ends of the compass are advantageously bored in accordance with the pivot of its two branches.

La longueur de chaque branche du compas peut aller de 0,7 à 0,1, de préférence de 0,5 à 0,15 , notamment de 0,4 à 0,15 , tout particulièrement de 0,3 à 0,2 mètre.The length of each leg of the compass can range from 0.7 to 0.1, preferably from 0.5 to 0.15, in particular from 0.4 to 0.15, more particularly from 0.3 to 0.2 meter. .

Le compas et les saillies doivent avoir une résistance adaptée à leur utilisation. Les branches du compas sont avantageusement réalisées en acier comme les saillies.The compass and the projections must have a resistance adapted to their use. The branches of the compass are advantageously made of steel as the projections.

Une saillie sera avantageusement un téton par exemple serti, de diamètre environ 2 à 0,5 cm, particulièrement de 1,5 à 0,5 cm et tout particulièrement d'environ 1 cm. Sa longueur (dimension transversale par rapport à la longueur du compas) sera avantageusement de 0,5 à 5, de préférence de 0,5 à 4, notamment de 1 à 3, particulièrement de 1,5 à 2,5 cm et tout particulièrement d'environ 2 cmA projection will advantageously be a nipple for example crimped, of diameter about 2 to 0.5 cm, particularly 1.5 to 0.5 cm and most preferably about 1 cm. Its length (dimension transverse to the length of the compass) will advantageously be from 0.5 to 5, preferably from 0.5 to 4, in particular from 1 to 3, particularly from 1.5 to 2.5 cm, and most particularly about 2 cm

Les dispositifs objet de la présente invention possèdent de très intéressantes qualités. Ils permettent notamment d'être utilisés pour des cuvettes d'ascenseur peu profondes. Ils peuvent ne se déployer qu'en position semi verticale et de disposer d'un verrouillage automatique des jambes de force (compas). Ils ont une grande résistance à une force radiale et les jambes de force se replient automatiquement lors du repliement de l'ensemble. Le déploiement peut être amorti.The devices object of the present invention have very interesting qualities. They allow in particular to be used for shallow lift bowls. They can only deploy in a semi-vertical position and have an automatic strut lock (compass). They have great resistance to radial force and the struts fold back automatically when folding the set. Deployment can be amortized.

Ces qualités sont illustrées ci-après dans la partie expérimentale. Elles justifient l'utilisation des chasse pieds ci-dessus décrits, dans la protection des personnes lors des dysfonctionnements ou réparations d'ascenseurs.These qualities are illustrated below in the experimental part. They justify the use of hunt feet described above, in the protection of people during malfunctions or repairs of lifts.

C'est pourquoi la présente demande a enfin pour objet un procédé de protection dans lequel on installe un dispositif ci-dessus sous une cabine d'ascenseur.This is why the present application finally relates to a method of protection in which a device above is installed under an elevator car.

Les dispositifs décrits ci-dessus trouvent aussi leur application dans les mobiliers dits "gain de place" escamotables ou repliables. Par exemple ils peuvent être utilisés pour déployer et ranger un écran de projection, une échelle télescopique ou un escalier escamotable.The devices described above also find their application in so-called "space saving" furniture retractable or collapsible. For example they can be used to deploy and store a projection screen, a telescopic ladder or a retractable staircase.

Les conditions préférentielles de mise en oeuvre des procédés ci-dessus décrites s'appliquent également aux autres objets de l'invention visés ci-dessus, notamment aux chasse pieds de l'invention et inversement.The preferred conditions of implementation of the methods described above also apply to the other objects of the invention referred to above, in particular to hunt feet of the invention and vice versa.

Dans la description qui suit, le montage est expérimental et divers modes ou formes de réalisation sont possibles. Par exemple la pièce multifonctionnelle est fixée par soudure sur un compas mais peut être réalisée d'une pièce avec le bras distal du compas.In the following description, the mounting is experimental and various modes or embodiments are possible. For example the multifunctional part is fixed by welding on a compass but can be performed in one piece with the distal arm of the compass.

Sur la figure 1, on distingue l'extrémité distale d'un compas 1 de section transversale en U, sur lequel est fixée par soudure une pièce multifonctionnelle 2 de l'invention. Le compas 1 étant un compas d'articulation, chacune de ses extrémités est montée sur un pivot, du côté distal à un panneau proximal 8, du côté distal à une cabine d'ascenseur ou comme représenté ici, à un coffrage 7 de rangement du dispositif. La pièce multifonctionnelle 2 vue de côté est une plaque 3 en forme de L, installée du côté de la fermeture du compas. Elle comprend un repli longitudinal 4 allongé prévu environ parallèlement à la longueur du bras du compas 1. Elle comprend deux saillies 5 (cachée sur cette figure) et 6 dirigées vers l'intérieur du dispositif. On trouve une saillie de repliement appelée saillie distale en raison de sa position, saillie distale qui est un téton 5 serti en acier de diamètre environ 1 cm et de longueur d'environ 2 cm et une saillie de blocage 6 appelée aussi saillie proximale en raison de sa position, qui est elle-même un coude transversal de la plaque 3 pour procurer un décrochement.On the figure 1 , there is the distal end of a compass 1 of U cross section, on which is fixed by welding a multifunctional part 2 of the invention. The compass 1 being a hinge compass, each of its ends is mounted on a pivot, the distal side to a proximal panel 8, the distal side to an elevator car or as shown here, a formwork 7 storage of device. The multifunctional part 2 seen from the side is a plate 3 L-shaped, installed on the side of the closure of the compass. It comprises an elongate longitudinal fold 4 provided approximately parallel to the length of the arm of the compass 1. It comprises two projections 5 (hidden on this figure) and 6 directed towards the inside of the device. There is a distal protrusion called distal protrusion due to its distal projection position which is a steel crimped nipple about 1 cm in diameter and about 2 cm in length and a locking protrusion 6 also referred to as a proximal projection due to its position, which is itself a transverse bend of the plate 3 to provide a recess.

Sur la figure 2, on distingue les mêmes éléments, ainsi que la saillie de repliement qui est un téton 5.On the figure 2 , we distinguish the same elements, as well as the folding projection which is a nipple 5.

Sur la figure 3, on distingue le coffrage 7 environ parallélépipédique dans lequel sont repliés à l'origine les panneaux. Le déverrouillage des panneaux est intervenu, ce qui a provoqué leur pivotement vers la verticale (voir flèche) et l'ouverture partielle du compas 1 dont les deux branches ne sont pas encore alignées. On distingue un côté du panneau proximal 8 et une petite partie distale du panneau distal 9. Le panneau distal 9 est muni d'un profilé 10 protubérant installé parallèlement aux flancs des panneaux et muni d'un téton 11 transversal. A l'origine lorsque les panneaux sont repliés dans le coffrage, la saillie de blocage 6 en coopération avec le téton 11 transversal bloque les mouvements de translation relative des panneaux. Dans la position représentée, l'ouverture du coffrage a provoqué le pivotement antihoraire (horaire vu du côté opposé) des panneaux et en conséquence le pivotement antihoraire (horaire vu du côté opposé) du bras distal du compas 1 par rapport à son axe distal de rotation matérialisé par un pivot 12, et de ce fait de la pièce 2 multifonctionnelle de l'invention laissant progressivement le passage vers le bas au téton 11 transversal et de ce fait au panneau distal 9. On observe aussi une patte protubérante prévue latéralement sur le panneau distal 9 et dont on expliquera ensuite la fonction.On the figure 3 , we distinguish the formwork 7 approximately parallelepiped in which are folded at the origin panels. Unlocking the panels intervened, which caused their pivoting to the vertical (see arrow) and the partial opening of the compass 1 whose two branches are not yet aligned. There is a side of the proximal panel 8 and a small distal portion of the distal panel 9. The distal panel 9 is provided with a protruding section 10 installed parallel to the sides of the panels and provided with a nipple 11 transverse. Originally when the panels are folded into the formwork, the locking projection 6 in cooperation with the transverse stud 11 blocks the relative translation movements of the panels. In the position shown, the opening of the formwork caused the counterclockwise rotation (clockwise seen from the opposite side) of the panels and consequently the counterclockwise rotation (clockwise seen from the opposite side) of the distal arm of the compass 1 relative to its distal axis. rotation materialized by a pivot 12, and thereby the multifunctional part 2 of the invention gradually leaving the passage down to the transverse nipple 11 and thus to the distal panel 9. There is also a protruding lug provided laterally on the distal panel 9 and whose function will be explained later.

La figure 4 représente une vue en perspective analogue à la figure 3, lors de la fermeture. On observe tout d'abord la symétrie générale de l'ensemble des éléments structurels. On observe ensuite les pattes protubérantes 13 en coin profilé installées latéralement et distalement sur le panneau distal 9. Lors de la fermeture, les pattes protubérantes 13 en coulissant viennent pousser le téton 5 de la pièce 2 multifonctionnelle de l'invention, provoquant son pivotement et en conséquence celui du bras distal du compas 1 par rapport à son axe distal de rotation 12 et ainsi le début de fermeture du compas, autorisant de ce fait le pivotement des panneaux pour leur rangement dans le coffrage 7.The figure 4 represents a perspective view similar to the figure 3 when closing. We first observe the general symmetry of all the structural elements. The protuberant lugs 13 are then seen in a profiled corner installed laterally and distally on the distal panel 9. During closure, the protruding lugs 13 slidably push the nipple 5 of the multifunctional part 2 of the invention, causing its pivoting and accordingly that of the distal arm of the compass 1 relative to its distal axis of rotation 12 and thus the beginning of closure of the compass, thus allowing the pivoting of the panels for their storage in the formwork 7.

La figure 5 montre une phase de remontée avant repliement mais peut aussi illustrer la poursuite de l'ouverture complète du dispositif (et sa fermeture comme indiqué ci-après). L'ouverture totale du compas 1 dont les deux branches sont alignées a été atteinte. Les tétons transversaux 11 du panneau distal 9 n'étant plus bloqués par les saillies de blocage 6 des pièces multifonctionnelles 2, le panneau distal 9 peut être entrainé par son poids et entrainer avec lui le panneau intermédiaire peu visible sur cette figure.The figure 5 shows a recovery phase before folding but can also illustrate the continuation of the complete opening of the device (and its closure as shown below). The total opening of the compass 1 whose two branches are aligned has been reached. The transverse nipples 11 of the distal panel 9 are no longer blocked by the locking projections 6 of the multifunctional parts 2, the distal panel 9 can be driven by its weight and cause with it the intermediate panel not visible in this figure.

La figure 6 illustre la poursuite de l'ouverture complète du dispositif. Le panneau distal 9 a été entrainé par son poids et a entrainé avec lui le panneau intermédiaire 14. La descente des panneaux a été ralentie par un jeu d'amortisseurs 20, 21 prévus entre le panneau proximal 8 et le panneau intermédiaire 14 et entre le panneau intermédiaire 14 et le panneau distal 9.The figure 6 illustrates the continuation of the complete opening of the device. The distal panel 9 has been driven by its weight and has carried with it the intermediate panel 14. The descent of the panels has been slowed by a set of dampers 20, 21 provided between the proximal panel 8 and the intermediate panel 14 and between the intermediate panel 14 and the distal panel 9.

Le panneau intermédiaire 14 est latéralement muni de cornières en L 15 qui viennent buter sur le téton 5 de la pièce 2 multifonctionnelle pour limiter la translation vers le bas du panneau intermédiaire 14 et verrouiller le compas. De même un système de butées limite la translation vers le bas du panneau distal 9 vis-à-vis du panneau intermédiaire 14.The intermediate panel 14 is laterally provided with L-shaped angles 15 which abut on the stud 5 of the multifunctional part 2 to limit the downward translation of the intermediate panel 14 and lock the compass. Likewise, a system of abutments limits the translation downward of the distal panel 9 with respect to the intermediate panel 14.

La figure 6 illustre aussi la fermeture du dispositif. La traction, relayée par poulie, sur un câble non représenté relié au coffrage, produit la remontée du panneau distal 9 dont le côté proximal vient en butée d'un repli distal 17 du panneau intermédiaire 14, auquel sont fixés trois amortisseurs 20, 21. La traction continuant produit aussi la remontée du panneau intermédiaire 14.The figure 6 also illustrates the closure of the device. The traction, relayed by pulley, on an unrepresented cable connected to the formwork, produces the rise of the distal panel 9 whose proximal side abuts a distal fold 17 of the intermediate panel 14, to which three dampers 20, 21 are attached. The continuous traction also produces the rise of the intermediate panel 14.

La traction continuant encore, comme illustré aussi sur la figure 5 puis sur la figure 4, des langues 13 formant butée, prévues latéralement sur le côté distal du panneau distal 9, viennent appuyer sur les tétons 5 des pièces 2 multifonctionnelles, provoquant le pivotement des branches distales des compas 1 et le déblocage des compas 1 ainsi que le début de repliement des compas 1.The traction still continuing, as illustrated also on the figure 5 then on the figure 4 , tongues 13 forming a stop, provided laterally on the distal side of the distal panel 9, are pressed on the nipples 5 of the multifunctional parts 2, causing the pivoting of the distal branches of the compasses 1 and the release of the compasses 1 and the beginning of folding Compasses 1.

La traction continuant encore, les panneaux abandonnent leur position verticale.As the traction continues, the panels leave their vertical position.

La traction se poursuivant, comme illustré aussi sur la figure 3, les saillies de blocage 6, entrainées par le pivotement des pièces 2 multifonctionnelles (dans le sens horaire sur la figure 3), passent sous le téton 11 pour empêcher la descente du panneau distal 9 et en conséquence du panneau intermédiaire 14.The traction continues, as illustrated also on the figure 3 , the locking projections 6, driven by the pivoting parts 2 multifunctional (clockwise on the figure 3 ), pass under the pin 11 to prevent the descent of the distal panel 9 and consequently of the intermediate panel 14.

Les panneaux continuent à pivoter pour progressivement prendre une position environ horizontale en vue de se replier dans le coffrage comme représenté à la figure 7.The panels continue to pivot to gradually assume a horizontal position to fold into the formwork as shown in FIG. figure 7 .

La figure 7 illustre aussi le possible montage latéral d'amortisseurs 22 freinant le pivotement du panneau proximal 8 par rapport à une cabine d'ascenseur et dans le cas présent par rapport au coffrage 7. Une élingue de tarction 23 est fixée à une extrémité distale du compas au niveau de l'axe de rotation 12 et à l'autre extrémité au coffrage 7 par l'intermédiaire d'une pièce d'attache 24 du vérin amortisseur 22 au coffrage 7. L'élingue est renvoyée par un mouflage 26 et une poulie de renvoi 25.The figure 7 also illustrates the possible lateral mounting of dampers 22 braking the pivoting of the proximal panel 8 relative to an elevator car and in this case with respect to the formwork 7. A tarction sling 23 is attached to a distal end of the compass at level of the axis of rotation 12 and at the other end to the formwork 7 via an attachment piece 24 of the damper cylinder 22 to the formwork 7. The sling is returned by a haulage 26 and a pulley reference 25.

Dans un autre mode de réalisation, on n'a pas installé de câble de traction et le repliement des panneaux est réalisé manuellement.In another embodiment, no traction cable has been installed and the folding of the panels is done manually.
