Description
L'invention concerne un escabeau à plateforme rabattable et à montants pliables.The invention relates to a folding platform stool with folding uprights.
On connait par le document
- un plan de montée dont les montants sont reliés par des marches ou par des barreaux,
- une plateforme articulée sur les montants du plan de montée avec possibilité de saillir vers l'avant ou d'être rabattue contre le plan de montée,
- deux jambes d'appui, articulées près du sommet de chacun des deux montants par des articulations leur permettant d'occuper une position de rangement, dans laquelle elles sont contre les montants, et une position de stabilisation, dans laquelle elles sont écartées de ces montants, sur le coté et vers l'avant,
- des tirants contrôlant l'écartement des jambes, chaque tirant étant disposé entre la jambe et le montant sur lequel celle-ci est articulée,
- et des moyens d'écartement des jambes d'appui.
- a climbing plan whose amounts are connected by steps or bars,
- a platform articulated on the uprights of the plan of climb with possibility to project forward or to be folded against the plan of rise,
- two support legs, articulated near the top of each of the two uprights by articulations allowing them to occupy a storage position, in which they are against the uprights, and a stabilizing position, in which they are spaced from these amounts , on the side and towards the front,
- tie rods controlling the spacing of the legs, each tie being disposed between the leg and the amount on which it is articulated,
- and means for spacing the support legs.
Les documents
A cette fin, ceux-ci comprennent, pour chaque jambe d'appui :
- un bras écarteur disposé sous la plateforme articulée et dont une extrémité est articulée sur un pivot commun avec l'autre bras, alors que l'autre extrémité du bras est articulée sur un organe monté coulissant sur la jambe correspondante,
- - le tirant correspondant, dont une extrémité est liée au collier précité par une articulation, alors que son autre extrémité est articulée à un montant,
- ces deux éléments bras et tirant constituant deux des cotés d'un triangle dont la déformation du troisième coté, formé entre le pivot et l'articulation du tirant sur le montant, modifie la position de l'organe coulissant sur la jambe et l'angulation de la jambe par rapport au montant.
- a spreader arm disposed under the articulated platform and one end of which is articulated on a common pivot with the other arm, while the other end of the arm is articulated on a member slidably mounted on the corresponding leg,
- the corresponding tie rod, one end of which is connected to the aforementioned collar by a hinge, while its other end is hinged to an upright,
- these two arms and pulling elements constituting two sides of a triangle whose deformation of the third side formed between the pivot and the articulation of the pulling on the upright, modifies the position of the sliding member on the leg and the angulation leg compared to the amount.
Cette construction facilite le déploiement de l'escabeau et garantit que, à l'état déployé, il offre une stabilité améliorant la sécurité du personnel qui l'emprunte.This construction facilitates the deployment of the stepladder and ensures that, in the deployed state, it provides stability improving the safety of staff who borrows.
Bien que conçu pour effectuer des travaux à des hauteurs comprises entre 2,5 et 4 mètres, il apparait qu'un tel escabeau est encore trop encombrant en hauteur et de ce fait est difficilement rangeable dans une petite camionnette pouvant se garer aisément dans un centre urbain et à proximité du lieu de travail. Il en résulte que l'opérateur chargé d'effectuer des opérations d'entretien en centre ville, à une hauteur de l'ordre de 2,50 mètres, par exemple dans un couloir de bureau ou dans un couloir de métropolitain, est soumis à l'alternative suivante :
- remplacer l'escabeau par un marchepied, plus facilement transportable dans une camionnette ou dans un véhicule personnel, avec l'inconvénient sur le lieu de travail, de nécessiter des étirements de l'opérateur pour devoir atteindre les éléments hauts devant être entretenus,
- avoir recours à un escabeau adapté en hauteur, mais faire appel à un autre opérateur pour transporter l'escabeau dans un camion et, en cas de difficultés de stationnement, se faire déposer avec l'escabeau le plus près possible du lieu de travail, en prenant le risque d'avoir à déplacer l'escabeau sur une grande distance pour parvenir jusqu'au lieu de travail.
- replace the step ladder by a step, more easily transportable in a van or in a personal vehicle, with the disadvantage in the workplace, to require stretching of the operator to reach the high elements to be maintained,
- use a stepladder adapted to the height, but use another operator to transport the ladder in a truck and, in case of parking difficulties, be dropped off with the stepladder as close as possible to the workplace, taking the risk of having to move the stepladder a great distance to get to the place of work.
Le document
La présente invention à pour but de remédier à ces inconvénients en fournissant un escabeau selon la revendication 1 dont l'encombrement en hauteur peut être réduit pour son transport et son rangement, sans que les modifications de sa structure altèrent l'automatisme de son déploiement et de son repliements , ni sa résistance et ni sa stabilité à l'état déployé.The present invention aims to remedy these drawbacks by providing a stepladder according to claim 1 whose height space can be reduced for its transport and storage, without changes in its structure alter the automation of its deployment and its folds, nor its resistance and its stability in the deployed state.
A cette fin, dans l'escabeau selon l'invention, chacun des montants est composé d'une partie supérieure et d'une partie inférieure liée l'une à l'autre par une articulation à positions verrouillables permettant de disposer et verrouiller la partie inférieure dans le prolongement de la partie supérieure ou de la rabattre contre celle-ci en emprisonnant les jambes d'appui rétractées, tandis que chacune des jambes télescopiques d'appui est composée d'une partie supérieure articulée sur le montant et d'une partie inférieure montée coulissante sur l'extérieur de celle supérieure, l'extrémité de cette partie inférieure de jambe portant une articulation complexe sur laquelle sont articulées, d'une part, l'extrémité du tirant fixe correspondant et, d'autre part, l'extrémité du bras écarteur correspondant, afin que les jambes (6) s'allongent quand la plateforme (4) est amenée en position d'utilisation.To this end, in the stepladder according to the invention, each of the uprights is composed of an upper part and a lower part connected to each other by a hinge with locking positions to arrange and lock the part lower in the extension of the upper part or flap against it by trapping the retracted support legs, while each of the telescopic support leg is composed of an articulated upper part on the upright and a part lower slidably mounted on the outside of the upper, the end of the lower leg having a complex hinge on which are articulated on the one hand, the end of the corresponding fixed tie and, secondly, the end of the corresponding spacer arm, so that the legs (6) extend when the platform (4) is brought into use position.
Avec cet agencement, l'escabeau présente à l'état replié une hauteur réduite, comprise entre 1,4 et 1,6 mètre, permettant de le ranger aisément dans une camionnette ou une voiture particulière, en facilitant l'approche du lieu de travail, même dans les zones à stationnement difficile pour un camion.With this arrangement, the stool has in the folded state a reduced height, between 1.4 and 1.6 meters, for easy storage in a van or a particular car, facilitating the approach to the workplace , even in areas with difficult parking for a truck.
La mise en forme de l'escabeau comprend une phase préliminaire consistant, escabeau appuyé à plat contre le sol, à amener les parties inférieures des montants dans le prolongement de leurs parties supérieures en appui sur le sol, puis, après verrouillage automatique des articulations entre parties de montant, à redresser verticalement l'escabeau avant d'engager la procédure de déploiement de la plateforme assurant automatiquement l'écartement des jambes d'appui.The shaping of the stepladder comprises a preliminary phase consisting, stepladder pressed flat against the ground, to bring the lower parts of the uprights in the extension of their upper parts resting on the ground, and then, after automatic locking of the joints between parts of the upright, to straighten the step stool vertically before commencing the deployment of the platform automatically ensuring the spacing of the support legs.
Durant cette phase, l'organe qui coulisse sur chaque jambe et permet son déploiement lors de l'abaissement de la plateforme est directement constitué par l'extrémité supérieure de la jambe inférieure qui coulisse librement sur celle inférieure, en remplaçant avantageusement le collier utilisé dans les réalisations antérieures. Il en résulte que l'abaissement de la plateforme provoque le coulissement des parties inférieures des jambes sur les parties supérieures et l'allongement automatique des jambes.During this phase, the member which slides on each leg and allows its deployment during the lowering of the platform is directly constituted by the upper end of the lower leg which slides freely on the lower, advantageously replacing the collar used in previous achievements. As a result, the lowering of the platform causes the lower legs to slide on the upper parts and the automatic lengthening of the legs.
Dans une forme d'exécution de l'invention, les articulations entre les parties respectivement supérieure et inférieure de chaque montant du plan de montée sont disposées verticalement au dessous du barreau constituant l'articulation avant de la plateforme.In one embodiment of the invention, the joints between the respectively upper and lower portions of each amount of the rise plane are arranged vertically below the bar constituting the front articulation of the platform.
Cela dégage la partie inférieure du plan de montée de tous mécanisme et contrainte et permet de la faire pivoter de sensiblement un demi tour pour la rabattre sans difficultés contre l'autre partie.This releases the lower part of the rise plan of any mechanism and constraint and allows it to rotate substantially half a turn to fold it without difficulty against the other party.

Avant que les moyens de l'invention ne soient décrits en détail, il est d'abord procédé à la description de l'escabeau de base, tel qu'il est décrit dans les documents
Comme montré sur les différentes figures, cet escabeau comprend :
- un plan de montée M, composée de
montants 2 et de barreaux 3, - une plateforme rabattable 4, articulée sur le
dernier barreau 3x, par des douilles 5, ou équivalents, disposées sous le bord postérieur de la plateforme et de manière que celle ci puisse se déployer vers l'avant ; - deux jambes télescopiques d'appui 6, articulées chacune au sommet de l'un des
montants 2, par l'intermédiaire d'unearticulation 7, multidirectionnelle ou à plusieurs degrés de liberté ; - deux tirants rigides et latéraux 10, dont une extrémité est articulée en 12 sur le
montant 2 correspondant, alors que l'autre est articulée en 9 sur un élément coulissant de lajambe 6 ; - un garde corps repliable 13 dont les branches latérales 14 sont articulées, près de leurs extrémités avant et par des
axes 15, aux sommets desmontants 2 ; - deux
bielles 16 reliant legarde corps 13 à la plateforme 4, chaque bielle étant articulée en 17 sur la plateforme et en 18 sur uncollier 19 monté coulissant sur labranche 14 correspondante ; - et deux bras écarteurs 22 qui, disposés sous la plateforme 4, sont articulés par leurs extrémité postérieures sur un pivot commun 23, (visible
figures 2 et6 ), orthogonal à la plateforme et saillant de son fond, tandis que leurs extrémités antérieures sont liées par unearticulation 24 à l'élément coulissant sur la jambe.
- a rise plan M, composed of
uprights 2 and bars 3, - a folding platform 4 articulated on the
last bar 3x, by sockets 5, or equivalent, arranged under the rear edge of the platform and so that it can be deployed forward; - two
telescopic support legs 6, each articulated to the top of one of theuprights 2, via ahinge 7, multidirectional or with several degrees of freedom; - two rigid and
lateral tie rods 10, one end of which is articulated at 12 on the corresponding upright 2, while the other is articulated at 9 on a sliding element of theleg 6; - a
collapsible guard 13 whoselateral branches 14 are hinged, near their front ends and bypins 15, to the vertices of theuprights 2; - two connecting
rods 16 connecting thebodyguard 13 to the platform 4, each rod being articulated at 17 on the platform and at 18 on acollar 19 slidably mounted on thecorresponding branch 14; - and two
spreader arms 22 which, arranged under the platform 4, are articulated by their posterior ends on a common pivot 23, (visiblefigures 2 and6 ), orthogonal to the platform and protruding from its bottom, while their anterior ends are linked by ahinge 24 to the sliding element on the leg.

Chacun des bras écarteur 22 traverse une ouverture formée dans une ferrure 25 rapportée sous la platine 4 et près de chacun de ses angles antérieurs. Les bords de chaque ouverture coopèrent avec le bras 22 correspondant pour le guider transversalement par rapport à la plateforme, afin que ses mouvements s'effectuent dans un plan parallèle à celui de la plateforme, quelle que soit la position de cette plateforme par rapport au plan de montée qui la porte.Each of the
Il ressort de cette description que, pour chaque jambe 6, les moyens d'écartement automatique comprennent un bras 22 et un tirant 10 qui sont articulés sur le même élément coulissant, et forment deux des cotés d'un triangle déformable, dont le troisième coté est virtuel et s'étend entre le pivot 23 et l'articulation 12 du tirant sur le montant 2.It follows from this description that for each
Selon l'invention, chacun des montants 2 est divisé en deux parties, au dessous du barreau 3x sur lequel est articulée la plateforme 4, à savoir une partie supérieure 2a, portant toutes les articulations du plan de montée M, et une partie inférieure 2b, portant les barreaux 3 d'accès à la plateforme 4. Ces deux parties sont reliées l'une à l'autre par une articulation 30 à verrouillage automatique de position, permettant de caler la partie 2b dans le prolongement de la partie 2a, ou de la caler contre la partie supérieure après pivotement d'un demi tour, et dans toutes positions intermédiaires nécessaires aux manoeuvres de repliement et de déploiement.According to the invention, each of the

Selon une autre caractéristique de l'invention, chacune des jambes télescopiques d'appui, composée de façon connue d'une partie supérieure 6a et d'une partie inférieure 6b, se différencie de la forme utilisée dans l'escabeau d'origine par les points suivants, bien visibles à la
- la partie inférieure 6b enveloppe la partie supérieure 6a sur laquelle elle coulisse, et
- extrémité supérieure de cette partie inférieure 6b est solidaire d'une ferrure 38
portant l'articulation 9 pour le tirant 10et l'articulation 24 pour le bras écarteur 22.
- the
lower part 6b envelops theupper part 6a on which it slides, and - upper end of this
lower part 6b is integral with a fitting 38 carrying thehinge 9 for thetie rod 10 and thehinge 24 for thespreader arm 22.
Dans la réalisation représentée, le blocage en position d'appui des deux parties 6a-6b de chaque jambe d'appui 6 est assurée par un doigt 39 engageable manuellement dans un alésage traversant de la partie 6b et dans l'un des alésages 40 prévus dans la partie 6a. Tout autre moyen de blocage peut être utilisé par l'homme de métier.In the embodiment shown, the locking in the bearing position of the two

Sur le chantier, le déploiement s'effectue intuitivement en retirant la sangle 43, en couchant la face arrière de l'escabeau sur le sol, en débloquant les articulations 30, en amenant les parties 2b des montants dans le prolongement des parties supérieures 2a et en redressant l'escabeau sensiblement à la verticale. A partir de cette position, un appui manuel contre le fond de la plateforme 4 amorce son basculement, l'écartement automatique des jambes d'appui 6 et leur allongement par coulissement des parties inférieures 6b sur celles 6a. Quand celles-ci se sont développées sur la longueur souhaitée pour stabiliser l'escabeau, leurs parties inférieures 6b sont verrouillées sur leurs parties 6a par les doigts 39.On the site, the deployment is carried out intuitively by removing the
A la fin de ce processus, les bielles 16 sont encore contre les montants 2a, comme montré à la
Dès que l'opérateur est installé sur la plateforme, il repousse les bielles 16 vers l'arrière en faisant coulisser leurs colliers 19 sur les branches 14 du garde corps 13, puis installe la lisse de sécurité 42. Il peut alors travailler en toute sécurité sans avoir à s'étirer.As soon as the operator is installed on the platform, he pushes the
Il ressort de la description qui précède que les modifications apportées à l'escabeau permettent de replier les montants de son plan de montée, sans perturber les moyens d'écartement automatique.It follows from the foregoing description that the modifications made to the step stool make it possible to fold up the uprights of its climb plan, without disturbing the automatic spacing means.
Bien évidemment, le repliement s'effectue en procédant d'une façon inverse à celle qui vient d'être décrite, avec une seule différence consistant à actionner les moyens de blocage des roues 33 avant de coucher l'escabeau face arrière contre le sol pour replier les montants. A défaut de cette précaution, le redressement de l'escabeau replié est très difficile car il roule sur le sol au fur et à mesure qu'il est redressé.Of course, the folding is carried out in a manner that is the opposite of that just described, with only one difference being to actuate the wheel locking means 33 before setting the ladder back against the ground for fold the amounts. In the absence of this precaution, the recovery of the folded stepladder is very difficult because it rolls on the ground as it is straightened.
