Description

La présente invention se rapporte à un dispositif d'accès en hauteur réglable destiné notamment, mais non exclusivement, aux ateliers de construction ou aux chantiers dans le domaine du bâtiment.The present invention relates to an adjustable height access device intended in particular, but not exclusively, to construction workshops or construction sites in the building field.

Des dispositifs d'accès en hauteur réglables connus, du type plate-forme de travail ou escabeau, comprennent usuellement au moins deux éléments d'échelle montés à coulissement l'un sur l'autre. Chaque élément d'échelle comprend alors deux montants parallèles et une série de marches espacées successivement les unes des autres d'une distance déterminée, et reliant chacune les deux montants parallèles. Le nombre de marches pour chaque élément d'échelle est variable, entre une première marche et une dernière marche.Known adjustable access devices of the work platform or stepladder type usually comprise at least two ladder elements slidably mounted on one another. Each ladder element then comprises two parallel uprights and a series of steps spaced successively from each other by a determined distance, and each connecting the two parallel uprights. The number of steps for each scale element is variable, between a first step and a last step.

Le document FR-A-2 957 967 décrit un dispositif d'accès en hauteur selon le préambule de la revendication 1.The document FR-A-2,957,967 discloses a height access device according to the preamble of claim 1.

Lorsque le dispositif d'accès comprend deux éléments d'échelle, un premier élément d'échelle rejoint une plate-forme, tandis que le second est destiné à venir prendre appui sur une paroi de sol. Les deux éléments d'échelle sont mutuellement reliés entre eux par des étriers formant glissières installés sur les montants de manière à, non seulement pouvoir les maintenir superposés, mais aussi à autoriser leur coulissement l'un par rapport à l'autre. En outre, le second est équipé de deux organes de blocage montés respectivement à pivotement sur les montants et au-delà de la dernière marche dans le prolongement de la série de marches, pour pouvoir venir en prise avec une marche du premier élément d'échelle en formant béquille. Les deux organes de blocage sont montés en regard l'un de l'autre et ils sont reliés entre eux par une tige de manière à pouvoir être entraînés simultanément en pivotement. Grâce aux deux organes de blocage, les deux éléments d'échelle superposés peuvent être bloqués en translation dans un sens visant à les entraîner en coulissement l'un vers l'autre.When the access device comprises two scale elements, a first ladder element joins a platform, while the second is intended to bear against a floor wall. The two ladder elements are mutually connected to each other by stirrups forming rails mounted on the uprights so as not only to keep them superimposed, but also to allow them to slide relative to one another. In addition, the second is equipped with two locking members mounted respectively pivotally on the uprights and beyond the last step in the extension of the series of steps, to be able to come into engagement with a step of the first scale element by forming crutch. The two locking members are mounted facing one another and they are interconnected by a rod so as to be simultaneously driven in pivoting. Thanks to the two locking members, the two superimposed scale elements can be locked in translation in a direction intended to drive them sliding towards one another.

Le dispositif d'accès comporte également deux autres montants télescopiques reliant le premier élément d'échelle et la plate-forme pour pouvoir prendre appui sur la paroi de sol et maintenir les deux éléments d'échelle solidaires l'un de l'autre, inclinés selon une même direction par rapport à la paroi de sol, d'un angle compris entre 60° et 75°. Ainsi, un utilisateur accède à la plate-forme en prenant appui avec les pieds successivement sur les marches de la série de marches du premier élément d'échelle puis du second élément d'échelle.The access device also comprises two other telescopic uprights connecting the first ladder element and the platform to be able to rest on the floor wall and to keep the two ladder elements integral with one another, inclined according to the same direction relative to the floor wall at an angle of between 60 ° and 75 °. Thus, a user accesses the platform by pressing with the feet successively on the steps of the series of steps of the first scale element and the second scale element.

Les marches des deux séries de marche correspondant aux deux éléments d'échelle sont régulièrement espacées les unes des autres d'une distance constante correspondant à la distance déterminée. Toutefois, les deux éléments d'échelle étant superposés et écartés l'un de l'autre, lorsque les deux organes de blocage sont installés par rapport à la dernière marche, de telle sorte que l'on obtient une hauteur de marche, selon une direction verticale, constante en passant de l'un à l'autre des éléments d'échelle, la distance déterminée entre les marches selon une direction parallèle aux montants n'est, elle, plus constante. Inversement, lorsque les deux organes de blocage sont installés de manière à obtenir la distance déterminée entre les marches, constante selon la direction parallèle aux montants, la hauteur de marche selon une direction verticale n'est, à son tour, plus constante.The steps of the two steps corresponding to the two scale elements are regularly spaced from each other by a constant distance corresponding to the determined distance. However, the two ladder elements being superimposed and spaced from each other, when the two locking members are installed relative to the last step, so that a step height is obtained, according to a vertical direction, constant passing from one to the other scale elements, the distance determined between the steps in a direction parallel to the amounts is more constant. Conversely, when the two locking members are installed so as to obtain the determined distance between the steps, constant in the direction parallel to the uprights, the walking height in a vertical direction is, in turn, more constant.

Aussi, un problème qui se pose et que vise à résoudre la présente invention est de fournir un dispositif d'accès en hauteur réglable qui permette d'obtenir à la fois une hauteur de marche sensiblement constante selon une direction verticale et une distance entre les marches sensiblement constante selon la direction parallèle aux montants, lorsque l'on passe d'un élément d'échelle à l'autre.Also, a problem that arises and that aims to solve the present invention is to provide an adjustable height access device that allows to obtain both a substantially constant operating height in a vertical direction and a distance between the steps substantially constant in the direction parallel to the uprights when moving from one ladder element to another.

Dans le but de résoudre ce problème la présente invention propose un dispositif d'accès en hauteur réglable selon la revendication 1 comprenant deux éléments d'échelle montés à coulissement l'un sur l'autre, lesdits deux éléments d'échelle comportant chacun deux montants et une série de traverses successivement espacées les unes des autres d'une distance donnée, entre une première et une dernière traverse, l'un desdits deux éléments d'échelle comprenant des organes de blocage montés sur lesdits deux montants dans le prolongement de ladite série de traverses, lesdits organes de blocage étant mobiles entre une position escamotée et une position de blocage dans laquelle ils viennent en prise avec l'une des traverses de l'autre desdits deux éléments d'échelle de manière à pouvoir interdire le coulissement desdits deux éléments d'échelle l'un vers l'autre. Le dispositif d'accès en hauteur réglable comprend en outre une marche intermédiaire montée sur lesdits organes de blocage, et lorsque lesdits organes de blocage sont dans ladite position de blocage, ladite marche intermédiaire vient s'étendre au niveau de ladite une des traverses dudit autre desdits deux éléments d'échelle, et à une distance de ladite dernière traverse dudit un desdits deux éléments d'échelle égale à ladite distance donnée.In order to solve this problem, the present invention proposes an adjustable height access device according to claim 1 comprising two ladder elements slidably mounted on each other, said two ladder elements each comprising two uprights. and a series of crosspieces successively spaced apart from each other by a given distance, between a first and a last cross-member, one of said two ladder elements comprising locking members mounted on said two posts in the extension of said series cross members, said locking members being movable between a retracted position and a locking position in which they engage with one of the cross members of the other of said two ladder elements of so as to be able to prohibit the sliding of said two ladder elements towards each other. The adjustable height access device further comprises an intermediate step mounted on said locking members, and when said locking members are in said locking position, said intermediate step extends at said one of the sleepers of said other said two scale elements, and at a distance from said last crossbar of said one of said two scale elements equal to said given distance.

Ainsi, une caractéristique de l'invention réside dans la mise en oeuvre d'une marche intermédiaire sur le dispositif de blocage et qui vient alors s'étendre, selon une direction parallèle aux montants, dans le prolongement des traverses de ladite série de traverses dudit un desdits deux éléments d'échelle, et à ladite distance donnée de ladite dernière traverse. Au surplus, la marche intermédiaire définit un plan apte à venir s'étendre tangentiellement à la première traverse dudit autre desdits deux éléments d'échelle. En cela, elle vient s'étendre au niveau de la traverse. De la sorte, lorsque l'on passe de la dernière traverse dudit un desdits deux éléments d'échelle audit autre desdits deux éléments d'échelle, sur la marche intermédiaire, non seulement la hauteur de marche selon la direction verticale est égale à la hauteur de marche desdites série de traverses, mais au surplus, la distance entre la dernière traverse et la marche intermédiaire est identique à la distance séparant deux traverses des séries de traverses.Thus, a feature of the invention lies in the implementation of an intermediate step on the locking device and which then extends, in a direction parallel to the uprights, in the extension of the crosspieces of said series of sleepers said one of said two scale elements, and at said given distance from said last traverse. In addition, the intermediate step defines a plane adapted to extend tangentially to the first crosspiece of said other of said two scale elements. In this, it comes to extend at the cross. In this way, when passing from the last crossbar of said one of said two ladder elements to said other of said two ladder elements, on the intermediate step, not only is the step height in the vertical direction equal to the height. of said series of sleepers, but moreover, the distance between the last cross and the intermediate step is identical to the distance between two crosses of the series of sleepers.

En outre, lorsque les organes de blocage viennent en prise avec la première traverse dudit autre desdits deux éléments d'échelle, on observera que les autres traverses des deux éléments d'échelle définissent respectivement un même plan tangent sensiblement horizontal. De surcroît, dans cette dernière position relative des deux éléments d'échelle, les hauteurs de marche et distance entre la dernière traverse et la marche intermédiaire, sont également respectivement identiques aux hauteurs de marche et distance entre les traverses des séries de traverses.In addition, when the locking members engage with the first cross member of said other of said two scale elements, it will be observed that the other crosspieces of the two scale elements respectively define a same substantially horizontal tangent plane. In addition, in the latter relative position of the two scale elements, the operating heights and distance between the last crossbar and the intermediate step are also respectively identical to the running heights and distance between the crosses of the series of sleepers.

Selon l'invention, lesdits organes de blocage comprennent deux joues en regard respectivement montées à pivotement sur lesdits deux montants dudit un desdits deux éléments d'échelle. De la sorte, les organes de blocage viennent agir respectivement directement sur les montants appariés des deux éléments d'échelle. Partant, on obtient une meilleure résistance au coulissement des deux éléments d'échelle en situation de service, comme on l'expliquera plus en détail dans la description détaillée, et en particulier lorsque l'utilisateur prend appui sur les traverses dudit autre desdits deux éléments d'échelle.According to the invention, said locking members comprise two opposite cheeks respectively pivotally mounted on said two uprights of said one of said two scale elements. In this way, the locking members act respectively directly on the matched amounts of the two scale elements. Therefore, a better resistance to sliding of the two scale elements in a service situation is obtained, as will be explained in more detail in the detailed description, and in particular when the user is supported on the crosspieces of the other of said two elements. scale.

Aussi, chacune desdites joues comprend une extrémité de liaison reliée au montant et une extrémité de réception opposée présentant une encoche. De la sorte, les deux joues en regard sont adaptées à pivoter respectivement sur les deux montants, autour de leur extrémité de liaison. Ainsi, dans une position escamotée, les joues sont pivotées de manière à entraîner leur extrémité de réception entre les montants dudit un desdits deux éléments d'échelle. Dans ces conditions, les deux éléments d'échelle peuvent coulisser l'un par rapport à l'autre. Dans une position de blocage, l'extrémité de réception des joues est entraînée entre les deux montants dudit autre desdits deux éléments d'échelle pour venir en prise dans une traverse de l'autre desdits deux éléments d'échelle en formant béquille. Le coulissement des deux éléments d'échelle est alors interdit dans un sens visant à les entraîner l'un vers l'autre et correspondant à des conditions de service.Also, each of said cheeks comprises a connecting end connected to the upright and an opposite receiving end having a notch. In this way, the two opposite cheeks are adapted to pivot respectively on the two uprights, around their connecting end. Thus, in a retracted position, the cheeks are pivoted so as to cause their receiving end between the amounts of said one of said two scale elements. Under these conditions, the two ladder elements can slide relative to each other. In a locking position, the receiving end of the cheeks is driven between the two uprights of said other of said two ladder elements to engage a cross member of the other of said two ladder members as a crutch. The sliding of the two scale elements is then prohibited in a direction intended to drive them towards each other and corresponding to conditions of service.

Aussi, l'extrémité de liaison est reliée au montant, tandis que l'extrémité de réception opposée présentant une encoche, est située à l'opposé de ladite une dernière traverse par rapport à ladite extrémité de liaison. C'est grâce à ce mode de mise en oeuvre que le mode de blocage en formant béquille est rendu possible. Un tel mode de blocage, où le point de pivotement des joues est situé en dessous de l'extrémité de réception, permet aux organes de blocage de pouvoir demeurer en position d'équilibre dans la position escamotée.Also, the connecting end is connected to the upright, while the opposite receiving end having a notch, is located opposite said last one crosses relative to said connecting end. It is thanks to this mode of implementation that the locking mode by forming crutch is made possible. Such locking mode, where the pivot point of the cheeks is located below the receiving end, allows the locking members to remain in the equilibrium position in the retracted position.

De plus, chacune desdites joues présente de préférence une bordure latérale opposée à ladite extrémité de liaison et s'étendant vers ladite extrémité de réception, et les bordures latérales en regard desdites joues sont reliées ensemble par ladite marche intermédiaire. De la sorte, lorsque l'on vient exercer un effort vertical orienté du haut vers le bas sur la marche intermédiaire, notamment dans les conditions de service, cet effort est à la fois repris par les montants dudit un desdits deux éléments d'échelle au niveau des extrémités de liaison des joues, et par les traverses dudit autre desdits deux éléments d'échelle contre lesquelles vient s'appuyer la marche intermédiaire. On observera que dans ces conditions, les organes de blocage ne risquent pas d'être entraînés malencontreusement dans une position escamotée.In addition, each of said cheeks preferably has a side edge opposite said connecting end and extending towards said receiving end, and the side edges facing said cheeks are connected together by said intermediate step. In this way, when one comes to exert a vertical force directed from top to bottom on the intermediate step, in particular under the conditions of service, this effort is both taken up by the amounts of said one of said two ladder elements at the connection ends of the cheeks, and by the crosspieces of said other of said two ladder elements against which press the intermediate step. It will be observed that under these conditions, the locking members are not likely to be accidentally driven into a retracted position.

Selon une caractéristique préferentielle de l'invention particulièrement avantageuse, chacune desdites joues présente une lumière en arc autour de ladite extrémité de liaison, tandis que ledit montant présente un doigt d'arrêt s'étendant à l'intérieur de ladite lumière en arc. De la sorte, on vient limiter le mouvement en pivotement des joues par rapport au montant, entre la position escamotée et la position de blocage. Le doigt d'arrêt vient ainsi en butée dans les deux extrémités opposées de la lumière en arc.According to a particularly advantageous preferential characteristic of the invention, each of said cheeks has an arcuate light around said connecting end, whereas said upright has a stop finger extending inside said arcuate light. In this way, it comes to limit the pivotal movement of the cheeks relative to the amount, between the retracted position and the locking position. The stop finger thus abuts in the two opposite ends of the arcuate light.

En outre, les traverses des séries de traverses comportent de préférence des marches présentant une inclinaison constante par rapport auxdits montants. L'inclinaison des marches par rapport au montant est comprise, par exemple, entre 60° et 75°, de manière à ce que les marches demeurent sensiblement horizontales lorsque les deux éléments d'échelle sont maintenus ensemble selon une inclinaison comprise entre 60° et 75° par rapport à l'horizontale. On comprend que l'utilisateur conserve un meilleur équilibre lorsqu'il prend appui sur des marches sensiblement horizontales.In addition, the crosses of the series of sleepers preferably comprise steps having a constant inclination relative to said amounts. The inclination of the steps relative to the amount is, for example, between 60 ° and 75 °, so that the steps remain substantially horizontal when the two ladder elements are held together at an inclination of between 60 ° and 60 °. 75 ° to the horizontal. It is understood that the user maintains a better balance when supported on substantially horizontal steps.

Au surplus, chacun desdits éléments d'échelle présente de préférence deux étriers formant glissières respectivement montés sur lesdits deux montants. De la sorte, les deux éléments d'échelle sont mutuellement reliés l'un à l'autre, et ils peuvent coulisser l'un par rapport à l'autre en quatre points de liaison ce qui permet un meilleur guidage en translation.In addition, each of said ladder elements preferably has two stirrups forming slides respectively mounted on said two uprights. In this way, the two ladder elements are mutually connected to one another, and they can slide relative to one another at four connection points which allows better guidance in translation.

Préférentiellement, selon une variante de réalisation, le dispositif d'accès en hauteur comprend en outre une plateforme apte à venir en appui sur ladite dernière traverse dudit autre desdits deux éléments d'échelle. L'utilisateur ou l'opérateur, peut ainsi venir prendre appui sur la plate-forme avec ses deux pieds pour une meilleure stabilité. Avantageusement, le dispositif d'accès comprend en outre un support télescopique réglable relié audit autre desdits deux éléments d'échelle, et ledit support télescopique réglable est destiné à être maintenu en position inclinée par rapport audit autre desdits deux éléments d'échelle. Aussi, les deux éléments d'échelle, solidaires l'un de l'autre, sont maintenus en position fixe, inclinés par rapport à la paroi de sol, sans qu'un autre appui soit nécessaire. Par exemple, ledit support télescopique réglable comprend deux éléments supports montés à coulissement l'un sur l'autre, et un dispositif de blocage en translation d'un desdits deux éléments support par rapport à l'autre. De la sorte, lorsque la paroi de sol est uniforme, et lorsque l'on souhaite élever ladite plate-forme, on procède non seulement au réglage desdits deux éléments d'échelle mais aussi desdits deux éléments support, pour qu'elle demeure sensiblement horizontale.Preferably, according to an alternative embodiment, the height access device further comprises a platform adapted to bear on said last crosspiece of said other of said two scale elements. The user or the operator can come to bear on the platform with both feet for better stability. Advantageously, the access device further comprises an adjustable telescopic support connected to said other of said two scale elements, and said adjustable telescopic support is intended to be maintained in an inclined position with respect to said other of said two scale elements. Also, the two scale elements, integral with each other, are held in a fixed position, inclined relative to the floor wall, without another support is necessary. For example, said adjustable telescopic support comprises two support elements slidably mounted on one another, and a locking device in translation of one of said two support elements relative to the other. In this way, when the floor wall is uniform, and when it is desired to raise said platform, not only the adjustment of said two scale elements but also of said two support elements, so that it remains substantially horizontal .

La Figure 1 illustre un dispositif d'accès en hauteur réglable 10 et plus précisément une plate-forme de travail, dans une position de hauteur basse. Il comprend, d'un côté un plan de montée télescopique réglable 12 et de l'autre côté, un support télescopique réglable 14. En outre, le dispositif d'accès en hauteur réglable 10 comprend, entre le plan de montée télescopique réglable 12 et le support télescopique réglable 14, une plate-forme 16 surmontée d'un garde corps 18.The Figure 1 illustrates an adjustable height access device 10 and more precisely a work platform, in a low height position. It comprises, on one side an adjustable telescopic rise plane 12 and on the other side, an adjustable telescopic support 14. In addition, the adjustable height access device 10 comprises between the adjustable telescopic rise plane 12 and the adjustable telescopic support 14, a platform 16 surmounted by a guard 18.

Le plan de montée télescopique réglable 12 comporte deux éléments d'échelle montés à coulissement l'un sur l'autre, un élément d'échelle fixe 20 et un élément d'échelle mobile 22. L'élément d'échelle fixe 20 comprend deux premiers montants parallèles 24, 26 présentant deux premières extrémités opposées de liaison 28, 30, et une série de trois premières marches successives, une première première marche 32, une deuxième première marche 34 et une dernière première marche 36 au niveau de la plate-forme 16. Aussi, les deux premiers montants parallèles 24, 26 comportent deux premiers étriers formant glissières 37, 38 respectivement situés aux deux premières extrémités opposées de liaison 28, 30.The adjustable telescopic lift plane 12 has two ladder members slidably mounted on each other, a fixed ladder member 20 and a movable ladder member 22. The fixed ladder member 20 comprises two first parallel uprights 24, 26 having two first opposite ends of connection 28, 30, and a series of first three successive steps, a first first step 32, a second first step 34 and a last first step 36 at the platform 16. Also, the first two parallel uprights 24, 26 comprise two first slide-forming stirrups 37, 38 located respectively at the first two opposite ends of connection 28, 30.

L'élément d'échelle mobile 22 comprend deux seconds montants parallèles 40, 42 montés précisément coulissants, respectivement, dans les deux premiers étriers formant glissières 37, 38. On observera que les deux premiers étriers 37, 38 présentent respectivement une fente axiale interne non visible sur le dessin. Les deux fentes internes axiales sont orientées en regard l'une de l'autre et permettent ainsi d'autoriser le coulissement aux abords des marches, comme on l'expliquera ci-après, puisque ces dernières sont reliées aux montants, de chaque côté.The moving ladder element 22 comprises two parallel second uprights 40, 42 mounted precisely sliding, respectively, in the first two stirrups forming slideways 37, 38. It will be observed that the first two stirrups 37, 38 respectively have an internal axial slot which is not visible on the drawing. The two axial internal slots are oriented opposite one another and thus allow to allow sliding around the steps, as will be explained below, since the latter are connected to the amounts on each side.

Les deux seconds montants parallèles 40, 42 présentent deux secondes extrémités opposées de liaison 44, 46 et respectivement à l'opposé, deux extrémités d'appui 48, 50. Aussi, les deux seconds montants parallèles 40, 42 comportent deux seconds étriers formant glissières 52, 54, respectivement situés aux deux secondes extrémités opposées de liaison 44, 46. Les deux premiers montants parallèles 24, 26 sont à leur tour montés coulissant, respectivement, dans les deux seconds étriers formant glissières 52, 54. Ces derniers présentent également une fente axiale de passage des marches. On observera que les étriers formant glissières, les deux premiers 37, 38 et les deux seconds 52, 54, permettent de maintenir superposés les deux seconds montants parallèles 40, 42 et les deux premiers montants 24, 26, respectivement deux à deux.The two second parallel uprights 40, 42 have two opposite opposite ends of connection 44, 46 and respectively opposite, two bearing ends 48, 50. Also, the two second parallel uprights 40, 42 comprise two second stirrups forming slides 52, 54, respectively located at the two second opposite ends of connection 44, 46. The first two parallel uprights 24, 26 are in turn slidably mounted, respectively, in the two second stirrups forming slides 52, 54. These latter also have a axial slit of the steps. It will be observed that the stirrups forming slides, the first two 37, 38 and the two second 52, 54, allow to maintain superimposed the two second parallel uprights 40, 42 and the first two uprights 24, 26, respectively two by two.

L'élément d'échelle mobile 22 comprend une série de trois secondes marches successives, une première seconde marche 56, une deuxième seconde marche 58 et une troisième seconde marche 60, ou marche intermédiaire, que l'on décrira plus en détail en référence à la Figure 5 dans la suite de la description. La deuxième seconde marche 58 est la dernière marche de la série de deux secondes marches, lesquelles sont montées en position fixe sur les deux seconds montants parallèles 40, 42. La troisième seconde marche 60, ou marche intermédiaire est, elle, mobile comme on l'expliquera ci-après.The moving ladder element 22 comprises a series of three successive second steps, a first second step 56, a second second step 58 and a third second step 60, or intermediate step, which will be described in more detail with reference to the Figure 5 in the following description. The second second step 58 is the last step of the series of two second steps, which are mounted in a fixed position on the two second parallel uprights 40, 42. The third second step 60, or intermediate step is movable as it is. will explain below.

Avant d'entamer cette description, on se référera à la Figure 3 montrant le dispositif d'accès en hauteur réglable 10, dans une position de hauteur haute. Sur cette Figure, on retrouve les deux premiers montants parallèles 24, 26 et les deux seconds montants parallèles 40, 42, respectivement reliés l'un à l'autre par les deux premiers étriers 37, 38 et les deux seconds étriers 52, 54. Ainsi, par rapport à l'état du plan de montée télescopique réglable 12 illustré sur la Figure 1, il a été ici allongé, et plus précisément, l'élément d'échelle mobile 22 a été entraîné en translation par rapport à l'élément d'échelle fixe 20 selon un plan parallèle à ce dernier. Sur cette Figure on visualise la marche intermédiaire 60 et deux joues opposées, 62, 64 qu'elle relie et qui forment des organes de blocage. Ceux-ci, que l'on va décrire plus en détail en référence à la Figure 4, sont montés pivotants respectivement sur les deux seconds montants parallèles 40, 42, et sont en prise avec la première première marche 32 pour interdire le coulissement de l'élément d'échelle fixe 20 par rapport à l'élément d'échelle mobile 22.Before beginning this description, reference should be made to Figure 3 showing the adjustable height access device 10 in a high height position. In this Figure, there are the first two parallel uprights 24, 26 and the two second parallel uprights 40, 42, respectively connected to each other by the two first stirrups 37, 38 and the two second stirrups 52, 54. Thus, with respect to the state of the adjustable telescopic rise plane 12 illustrated on the Figure 1 it has been lengthened here, and more precisely, the moving ladder element 22 has been driven in translation relative to the fixed ladder element 20 in a plane parallel to the latter. In this Figure we visualize the intermediate step 60 and two opposing cheeks 62, 64 that connects and which form locking members. These, which will be described in more detail with reference to the Figure 4 , are pivotally mounted respectively on the two second parallel uprights 40, 42, and are engaged with the first first step 32 to prohibit the sliding of the fixed ladder element 20 with respect to the movable ladder element 22.

Sur la Figure 4, montrant, selon la flèche IV représentée sur la Figure 3, un plan de coupe orthogonal aux deux éléments d'échelle 20, 22, on retrouve les deux montants superposés, l'un des seconds montants 40 sur l'un des premiers montants 24, reliés ensemble par l'un des premiers étriers 37 et l'un des seconds étriers 52, et incliné par rapport à l'horizontale H d'un angle compris entre 60° et 75° et par exemple de 68°. La Figure 4 illustre plus clairement l'une des deux joues 64 formant l'organe de blocage. Celle-ci est de forme générale sensiblement triangulaire, et elle présente une extrémité de liaison 66, correspondant à l'un des sommets de la joue 64, et montée à rotation autour d'un axe 68 ancré dans le second montant 40, sensiblement perpendiculairement. Elle présente une extrémité de réception opposée 70, correspondant à un autre sommet et dans laquelle est pratiquée une encoche 72 recevant la première première marche 32. Cette dernière présente une première première surface d'appui 73 sensiblement horizontale. En outre, elle présente un côté opposé 74 à l'extrémité de liaison 66. Ce côté opposé 74 présente une bordure latérale 76 dans laquelle est ancrée la marche intermédiaire 60. La bordure latérale 76 s'étend parallèlement au côté opposé 74 du dernier sommet vers l'extrémité de réception 70. La marche intermédiaire 60 présente ainsi une surface d'appui 77 qui s'étend sensiblement horizontalement au niveau du côté opposé 74 de la joue 64 et également au niveau de la première première surface d'appui 73 de la première première marche 32. De plus, la joue 64 présente une lumière en arc 78 centrée autour de l'axe 68 et à l'intérieur duquel vient s'étendre un doigt d'arrêt 80 de manière à pouvoir limiter l'amplitude de pivotement de la joue 64. L'autre des deux joues 62 est identique et les deux joues 62, 64 s'étendent en regard l'une de l'autre.On the Figure 4 , showing, according to the arrow IV shown on the Figure 3 , a sectional plane orthogonal to the two ladder elements 20, 22, there are the two superposed uprights, one of the second uprights 40 on one of the first uprights 24, connected together by one of the first stirrups 37 and one of the second stirrups 52, and inclined relative to the horizontal H by an angle of between 60 ° and 75 ° and for example 68 °. The Figure 4 illustrates more clearly one of the two cheeks 64 forming the locking member. This is of generally triangular general shape, and it has an end of link 66, corresponding to one of the vertices of the cheek 64, and rotatably mounted about an axis 68 anchored in the second upright 40, substantially perpendicularly. It has an opposite receiving end 70, corresponding to another vertex and in which is formed a notch 72 receiving the first first step 32. The latter has a first first bearing surface 73 substantially horizontal. In addition, it has an opposite side 74 at the connecting end 66. This opposite side 74 has a side edge 76 in which is anchored the intermediate step 60. The side edge 76 extends parallel to the opposite side 74 of the last vertex towards the receiving end 70. The intermediate step 60 thus has a bearing surface 77 which extends substantially horizontally at the opposite side 74 of the cheek 64 and also at the level of the first first bearing surface 73 of the first first step 32. In addition, the flange 64 has an arcuate lumen 78 centered around the axis 68 and inside which extends a stop finger 80 so as to be able to limit the amplitude of pivoting the cheek 64. The other of the two cheeks 62 is identical and the two cheeks 62, 64 extend opposite one another.

Tels que représentés sur la Figure 4, on comprend que le second montant 40 et le premier montant 24 sont bloqués en translation l'un vers l'autre, selon une direction parallèle aux deux montants 40, 24, puisque la joue 64 vient dans cette position de blocage, former béquille.As represented on the Figure 4 it is understood that the second upright 40 and the first upright 24 are locked in translation towards one another, in a direction parallel to the two uprights 40, 24, since the cheek 64 comes into this locking position, forming crutch.

Avant de revenir sur la Figure 4 pour expliquer les avantages d'une telle configuration, on se reportera à la Figure 5 pour décrire le mode de fonctionnement des organes de blocage comprenant les joues 62, 64. On retrouve sur cette Figure 5, les deux premiers montants parallèles 24, 26 et les deux seconds montants parallèles 40, 40, respectivement reliés l'un à l'autre par les deux premiers étriers 37, 38 et les deux seconds étriers 52, 54. On retrouve également les deux joues opposées 62, 64 et la marche intermédiaire 60 qui les relie, dans une position escamotée. Dans cette position, les extrémités de réception 70 des joues 62, 64 sont entraînées entre les deux seconds montants parallèles 40, 42 tandis que les joues 62, 64 sont pivotées dans un sens opposé à la première première marche 32 qu'elles libèrent alors. Dans cette position, escamotée, les deux éléments d'échelle 20, peuvent être entraînés en coulissement l'un vers l'autre de manière à pouvoir quitter la position de hauteur haute.Before coming back to the Figure 4 to explain the advantages of such a configuration, we will refer to the Figure 5 to describe the mode of operation of the locking members comprising the cheeks 62, 64. Figure 5 , the first two parallel uprights 24, 26 and the two second parallel uprights 40, 40 respectively connected to one another by the two first stirrups 37, 38 and the two second stirrups 52, 54. There are also two opposite cheeks 62, 64 and the intermediate step 60 which connects them, in a retracted position. In this position, the receiving ends 70 of the cheeks 62, 64 are driven between the two parallel second legs 40, 42 while the cheeks 62, 64 are pivoted in a direction opposite to the first first step 32 which they then release. In this retracted position, the two ladder elements 20 can be slid towards each other so as to be able to leave the high height position.

On observera également que l'une des joues 64 est équipée d'un organe de verrouillage 82 rappelé par des moyens élastiques non représentés et qui permet de solidariser la joue 64 et la première première marche 32 dans la position de blocage. Cet organe de verrouillage 82 permet ainsi d'éviter l'entraînement intempestif en pivotement des joues 64, 62, car les deux joues 62, 64 sont solidaires l'une de l'autre grâce à la marche intermédiaire 60.We also observe that one of the cheeks 64 is equipped with a locking member 82 biased by not shown elastic means and which secures the cheek 64 and the first first step 32 in the locking position. This locking member 82 thus makes it possible to avoid inadvertent pivoting of the cheeks 64, 62, since the two cheeks 62, 64 are integral with each other by virtue of the intermediate step 60.

On se reportera de nouveau sur la Figure 4 sur laquelle sont également représentées la première seconde marche 56 et la seconde première marche 58 de l'élément d'échelle mobile 22, d'une part, ainsi que la deuxième première marche 34 et la dernière première marche 36 sur laquelle vient prendre appui tangentiellement la plate-forme 16.We will refer again to the Figure 4 on which are also represented the first second step 56 and the second first step 58 of the movable ladder element 22, on the one hand, and the second first step 34 and the last first step 36 on which is supported tangentially the platform 16.

Ainsi, grâce à la marche intermédiaire 60, la position relative des différentes marches et notamment au niveau de la transition entre les deux éléments d'échelle 20, 22, respectent des écarts constants. En effet, lorsque les joues 62, 64 sont dans une position de blocage, la surface d'appui 77 de la marche intermédiaire 60 s'étend sensiblement horizontalement et au niveau de la première première surface d'appui 73 de la première première marche 32. De la sorte, une hauteur de marche h unique, comprise par exemple entre 200 mm et 250 mm , s'étend verticalement, entre les surfaces d'appui des marches, et notamment, d'une part entre la seconde première marche 58 et la marche intermédiaire 60 et d'autre part entre la marche intermédiaire 60 et la deuxième première marche 34.Thus, thanks to the intermediate step 60, the relative position of the different steps and especially at the transition between the two scale elements 20, 22, respect constant differences. Indeed, when the cheeks 62, 64 are in a locking position, the bearing surface 77 of the intermediate step 60 extends substantially horizontally and at the first first bearing surface 73 of the first first step 32 In this way, a single walking height h , for example between 200 mm and 250 mm, extends vertically between the bearing surfaces of the steps, and in particular between the first step 58 and the first step 58. the intermediate step 60 and secondly between the intermediate step 60 and the second first step 34.

En outre, les deux seconds montants parallèles 40, 42, définissent un second plan moyen qui vient couper non seulement la première seconde marche 56 et la deuxième seconde marche 58, dernière marche de la série de de marche, mains aussi la marche intermédiaire 60. Selon ce second plan moyen, et une direction parallèle aux deux seconds montants 40, 42, les marches 56, 58, 60 sont régulièrement et successivement espacées les unes des autres sensiblement une même distance l comprise entre 230 mm et 300 mm, par exemple 250 mm. Au surplus, les deux premiers montants parallèles 24, 26 définissent un premier plan moyen qui vient couper la première première marche 32, la deuxième première marche 34 et la dernière première marche 36, et selon ce premier plan moyen, et une direction parallèle aux deux seconds montants 24, 26, les marches 32, 34, 60 sont régulièrement et successivement espacées les unes des autres sensiblement de ladite même distance l.In addition, the two second parallel uprights 40, 42 define a second middle plane which cuts not only the first second step 56 and the second second step 58, the last step of the march series, but also the intermediate step 60. According to this second average plane, and a direction parallel to the two second uprights 40, 42, the steps 56, 58, 60 are regularly and successively spaced some other substantially the same distance between 230 mm and 300 mm, eg 250 mm. In addition, the first two parallel uprights 24, 26 define a first middle plane which intersects the first first step 32, the second first step 34 and the last first step 36, and according to this first average plane, and a direction parallel to both second amounts 24, 26, the steps 32, 34, 60 are regularly and successively spaced from each other substantially the same distance l .

Ainsi, grâce à la marche intermédiaire 60, on obtient bien une continuité dans la position relative des marches en passant du premier élément d'échelle 20 au second élément d'échelle 22 ou inversement.Thus, thanks to the intermediate step 60, a continuity in the relative position of the steps is obtained while passing from the first scale element 20 to the second scale element 22 or vice versa.

On se reportera à présent sur la Figure 2, illustrant les éléments représentés sur la Figure 4, dans une configuration du dispositif d'accès en hauteur réglable 10 tel que représenté sur la Figure 1. Ainsi, il est dans une position de hauteur basse. On y retrouve les deux montants superposés, 40, 24, reliés ensemble par le premier 37 et le second étrier 52, et inclinés par rapport à l'horizontale H d'un angle de 68°. On y retrouve la joue 64 dont l'encoche 72 reçoit la dernière première marche 36. La surface d'appui 77 de la marche intermédiaire 60 s'étend alors sensiblement horizontalement et au niveau de la surface d'appui de la dernière première marche 36. On comprend également que le second montant 40 et le premier montant 24 sont bloqués en translation l'un vers l'autre selon une direction parallèle à ces montants, puisque la joue 64 vient dans cette position de blocage, former béquille.We will now refer to the Figure 2 , illustrating the elements represented on the Figure 4 in a configuration of the adjustable height access device 10 as shown in FIG. Figure 1 . Thus, he is in a low height position. There are the two superimposed uprights, 40, 24, interconnected by the first 37 and the second yoke 52, and inclined relative to the horizontal H by an angle of 68 °. It includes the cheek 64 whose notch 72 receives the last first step 36. The bearing surface 77 of the intermediate step 60 then extends substantially horizontally and at the bearing surface of the last first step 36 It is also understood that the second upright 40 and the first upright 24 are locked in translation towards each other in a direction parallel to these uprights, since the cheek 64 comes into this locking position, forming a crutch.

Aussi, dans cette position de hauteur basse, où le dispositif d'accès en hauteur ne présente plus que trois marches jusqu'à la plate-forme 16, les hauteurs de marche h entre les marches sont conservées, tout comme l'espacement des marches 56, 58, 60 les unes des autres de la distance l.Also, in this position of low height, where the height access device has only three steps to the platform 16, the walking heights h between the steps are maintained, as the spacing of the steps 56, 58, 60 from each other of the distance l .

Au surplus, on observera que, la première seconde marche 56 et la première première marche 32, la deuxième seconde marche 58 et la deuxième première marche 34, ainsi que la marche intermédiaire 60 et la dernière première marche 36, s'étendent respectivement au même niveau.Moreover, it will be observed that, the first second step 56 and the first first step 32, the second second step 58 and the second first step 34, as well as the intermediate step 60 and the last first step 36, respectively extend to the same level.

On se reportera de nouveau sur la Figure 3 illustrant le dispositif d'accès en hauteur dans la position de hauteur haute et en équilibre sur un plan horizontal. Le support télescopique 14 présente deux éléments support, un élément support fixe 84 et un élément support mobile 86. L'élément support fixe 84 présente deux premiers montants support 87, 88, tandis que l'élément support mobile 86 comporte deux seconds montants support 90, 92. Les deux premiers montants support 87, 88 sont reliés respectivement aux deux seconds montants support 90, 92 de manière coulissante au moyen de deux paires d'étriers 94, 96 formant glissières. En outre, les deux premiers montants support 87, 88 sont reliés entre eux par une série de premières traverses support 98, tandis que les deux seconds montants support 90, 92 sont reliés entre eux par une série de secondes traverses support 100. Au surplus, un dispositif de blocage comprenant deux pièces de blocage 102, 104, analogues aux joues 62, 64 décrites ci-dessus, permettent de bloquer en translation les montants supports respectivement, les uns par rapport aux autres.We will refer again to the Figure 3 illustrating the height access device in the position of high height and in equilibrium on a horizontal plane. The telescopic support 14 has two support members, a fixed support member 84 and a movable support member 86. The fixed support member 84 has two first support posts 87, 88, while the movable support member 86 has two second support posts 90 , 92. The first two support posts 87, 88 are respectively connected to the two second support posts 90, 92 in sliding manner by means of two pairs of stirrups 94, 96 forming slides. In addition, the first two support posts 87, 88 are interconnected by a series of first support crosspieces 98, while the two second support posts 90, 92 are interconnected by a series of second support rails 100. Moreover, a locking device comprising two locking pieces 102, 104, similar to the cheeks 62, 64 described above, allow to lock in translation the support amounts respectively, with respect to each other.

De la sorte, le réglage de la hauteur de la plate-forme 16, par rapport au plan horizontal, est réalisé en réglant à la fois l'élément d'échelle mobile 22 par rapport à l'élément d'échelle fixe 26 et l'élément support mobile 86 par rapport à l'élément support fixe 84.In this way, the adjustment of the height of the platform 16, relative to the horizontal plane, is achieved by adjusting both the mobile ladder element 22 relative to the fixed ladder element 26 and the movable support member 86 with respect to the fixed support member 84.
