Definitions

  • This invention relates to the field of manufacturing height access devices adopting an unfolded position in which an operator borrows this device to provide a height intervention and a folded position in which the device is transported, manipulated and / or stored . More particularly, this invention relates to folding height access devices incorporating a footrest and at least one guardrail, or even deployable / retractable means for adapting the height of the footrest to the height of the intervention to be assured.
  • Such height access devices comprise, then usually, two supports, a footrest and at least one guardrail.
  • such a height access device also comprises means for articulating at least one support relative to the other support, in order to give this device an unfolded position and a folded position.
  • the supports have a different length and that, in particular, the support mounted in an articulated manner on the other support has a length less than this other support.
  • such a footrest has dimensions such that, in folded configuration of the access device at height, the footrest protrudes laterally relative to the supports and generates a space detrimental to the compactness of this device. device.
  • such a footrest must be bordered by at least one skirting board which significantly increases the phenomenon of lateral overhang mentioned above.

  • the presence of such an organ does not, however, guarantee the safety of an operator borrowing such a device so that such hoop was replaced by a frame extending to the front and back said support and articulated on this support.
  • a first disadvantage of such a framework is that the operator, borrowing the device, must slip through this frame, often by contorting, which is dangerous, difficult, and likely to cause injury.
  • this frame and the means for mounting this frame articulately on a support significantly exceed laterally with respect to the supports in folded configuration of the device which, again, increases the lateral size of the device once folded.
  • a height access device also includes, in the usual manner, two elements each designed to extend a support and thus to modify the height of the footrest with respect to the ground.
  • an element for extending a support can, then at most, have a length corresponding to the length of this support. Also, and since one of the supports of the device is shorter than the other support, the length of the elements to extend these supports is then limited by the length of the element equipping the shortest support. As a result, then, the maximum height at which the footrest can be positioned is limited by the length of the shortest member and, therefore, the length of the shorter support.
  • the present invention is intended to overcome the disadvantages of height access devices of the state of the art.

This results in a substantial improvement in the compactness of the device, more particularly the depth of this device, in the folded position of this device.
  • Such a characteristic also makes it possible to confer on the two supports of an access device at height a substantially identical length.

Description

La présente invention a trait à un dispositif d'accès en hauteur de type repliable adoptant, plus particulièrement, la forme d'une plateforme, d'un marchepied ou d'une échelle.The present invention relates to a folding type height access device adopting, more particularly, the form of a platform, a step or a ladder.

Cette invention concerne le domaine de la fabrication des dispositifs d'accès en hauteur adoptant une position dépliée dans laquelle un opérateur emprunte ce dispositif pour assurer une intervention en hauteur ainsi qu'une position repliée dans laquelle ce dispositif est transporté, manipulé et/ou stocké. Cette invention concerne, plus particulièrement, les dispositifs d'accès en hauteur repliables incorporant un repose-pied ainsi qu'au moins un garde-corps, voire encore des moyens déployables/rétractables pour adapter la hauteur de ce repose-pied à la hauteur de l'intervention à assurer.This invention relates to the field of manufacturing height access devices adopting an unfolded position in which an operator borrows this device to provide a height intervention and a folded position in which the device is transported, manipulated and / or stored . More particularly, this invention relates to folding height access devices incorporating a footrest and at least one guardrail, or even deployable / retractable means for adapting the height of the footrest to the height of the intervention to be assured.

L'on connaît, d'ores et déjà, des dispositifs d'accès en hauteur présentant les caractéristiques mentionnées ci-dessus.Already known, height access devices having the characteristics mentioned above.

De tels dispositifs d'accès en hauteur comportent, alors usuellement, deux supports, un repose-pied ainsi qu'au moins un garde-corps.Such height access devices comprise, then usually, two supports, a footrest and at least one guardrail.

En fait, un tel dispositif d'accès en hauteur comporte, également, des moyens pour articuler au moins un support par rapport à l'autre support, ceci en vue de conférer à ce dispositif une position dépliée ainsi qu'une position repliée.In fact, such a height access device also comprises means for articulating at least one support relative to the other support, in order to give this device an unfolded position and a folded position.

A ce propos, on observera que c'est, usuellement, l'extrémité supérieure d'un tel support qui est alors montée de manière articulée sur une partie intermédiaire, interposée entre l'extrémité supérieure et l'extrémité inférieure, de l'autre support, ceci par l'intermédiaire de ces moyens pour articuler.In this regard, it will be observed that it is usually the upper end of such a support which is then mounted in an articulated manner on an intermediate portion interposed between the upper end and the lower end, the other support, this through these means to articulate.

Un tel montage confère, alors, au dispositif d'accès en hauteur une configuration en « X », ceci en position dépliée de ce dispositif.Such an arrangement then confers on the height access device an "X" configuration, in the unfolded position of this device.

Pour la réalisation d'un tel montage, il est, alors, nécessaire que les supports présentent une longueur différente et que, en particulier, le support monté de manière articulée sur l'autre support présente une longueur inférieure à cet autre support.For the realization of such an assembly, it is then necessary that the supports have a different length and that, in particular, the support mounted in an articulated manner on the other support has a length less than this other support.

C'est, usuellement, sur cet autre support de longueur supérieure que sont, alors, articulés le repose-pieds et/ou au moins un garde-corps.It is usually on this other support of greater length that are then articulated the footrest and / or at least one guardrail.

A ce propos, on observera qu'un tel repose-pieds présente des dimensions telles que, en configuration repliée du dispositif d'accès en hauteur, ce repose-pieds dépasse latéralement par rapport aux supports et génère un encombrement préjudiciable à la compacité de ce dispositif. De plus, en raison de la réglementation en matière de dispositifs d'accès en hauteur, un tel repose-pieds doit être bordé par au moins une plinthe qui accentue notablement le phénomène de dépassement latéral susmentionné.In this regard, it will be observed that such a footrest has dimensions such that, in folded configuration of the access device at height, the footrest protrudes laterally relative to the supports and generates a space detrimental to the compactness of this device. device. In addition, because of the regulation of access devices in height, such a footrest must be bordered by at least one skirting board which significantly increases the phenomenon of lateral overhang mentioned above.

En ce qui concerne le garde-corps (usuellement dénommé lisse), celui-ci adopte la forme d'un arceau, monté articulé sur cet autre support, et présentant des branches parallèles s'étendant à l'arrière de cet autre support. Un organe sous forme d'une chaîne ou d'une ficelle amovible raccorde l'extrémité des deux branches pour refermer le garde-corps. La présence d'un tel organe ne permet, cependant, pas de garantir la sécurité d'un opérateur empruntant un tel dispositif de sorte qu'un tel arceau a été remplacé par un cadre s'étendant à l'avant et à l'arrière dudit support et monté articulé sur ce support. Un premier inconvénient d'un tel cadre consiste en ce que l'opérateur, empruntant le dispositif, doit se glisser au travers de ce cadre, souvent en se contorsionnant, ce qui est dangereux, malaisé, et susceptible d'engendrer des lésions. Ces inconvénients sont amplifiés par le nombre de montées/descentes du dispositif effectué par l'opérateur ainsi que par le fait que cet opérateur est susceptible de porter des outils et/ou du matériel.Regarding the guardrail (usually called smooth), it adopts the form of a hoop mounted articulated on the other support, and having parallel branches extending to the rear of the other support. A member in the form of a chain or a removable string connects the ends of the two branches to close the railing. The presence of such an organ does not, however, guarantee the safety of an operator borrowing such a device so that such hoop was replaced by a frame extending to the front and back said support and articulated on this support. A first disadvantage of such a framework is that the operator, borrowing the device, must slip through this frame, often by contorting, which is dangerous, difficult, and likely to cause injury. These disadvantages are amplified by the number of ascents / descents of the device made by the operator as well as by the fact that this operator is likely to wear tools and / or equipment.

De plus, ce cadre et les moyens pour monter ce cadre de manière articulée sur un support dépassent, de manière notable, latéralement par rapport aux supports en configuration repliée du dispositif ce qui, là encore, accroit l'encombrement latéral du dispositif une fois replié.In addition, this frame and the means for mounting this frame articulately on a support significantly exceed laterally with respect to the supports in folded configuration of the device which, again, increases the lateral size of the device once folded.

Les inconvénients mentionnés ci-dessus sont, bien entendu, amplifiés par la présence d'un autre garde corps (usuellement dénommé sous-lisse) que la réglementation impose.The disadvantages mentioned above are, of course, amplified by the presence of another guard (usually called sub-smooth) that the regulations impose.

On observera, qu'un dispositif d'accès en hauteur comporte, également et de manière usuelle, deux éléments conçus, chacun, pour prolonger un support et, ainsi, pour modifier la hauteur du repose-pied par rapport au sol.It will be observed that a height access device also includes, in the usual manner, two elements each designed to extend a support and thus to modify the height of the footrest with respect to the ground.

A ce propos, on observera qu'un élément pour prolonger un support (et qui équipe un tel support) peut, alors au maximum, présenter une longueur correspondant à la longueur de ce support. Aussi et étant donné que l'un des supports du dispositif est plus court que l'autre support, la longueur des éléments pour prolonger ces supports est, alors, limitée par la longueur de l'élément équipant le support le plus court. Il en résulte, alors, que la hauteur maximale à laquelle il est possible de positionner le repose-pied est limitée par la longueur de l'élément le plus court et, par conséquent, par la longueur du support le plus court.In this regard, it will be observed that an element for extending a support (and which equips such a support) can, then at most, have a length corresponding to the length of this support. Also, and since one of the supports of the device is shorter than the other support, the length of the elements to extend these supports is then limited by the length of the element equipping the shortest support. As a result, then, the maximum height at which the footrest can be positioned is limited by the length of the shortest member and, therefore, the length of the shorter support.

La présente invention se veut de remédier aux inconvénients des dispositifs d'accès en hauteur de l'état de la technique.The present invention is intended to overcome the disadvantages of height access devices of the state of the art.

A cet effet, l'invention concerne un dispositif d'accès en hauteur de type repliable et comportant :

  • deux supports ainsi que des moyens pour articuler au moins un support par rapport à l'autre support, ceci entre une position repliée et une position dépliée du dispositif ;
  • un repose-pied s'étendant entre les deux supports ;
  • au moins un garde corps ;
  • caractérisé par le fait que chaque support comporte une partie supérieure recevant au moins une partie d'au moins un garde corps, une partie inférieure recevant au moins une partie du repose-pied, et une partie intermédiaire, interposée entre la partie supérieure et la partie inférieure, et recevant au moins une partie des moyens pour articuler un tel support par rapport à l'autre support.
For this purpose, the invention relates to a height access device of the folding type and comprising:
  • two supports as well as means for articulating at least one support relative to the other support, this between a folded position and an unfolded position of the device;
  • a footrest extending between the two supports;
  • at least one guardrail;
  • characterized in that each support comprises an upper part receiving at least a part of at least one guard, a lower part receiving at least a part of the footrest, and an intermediate part, interposed between the upper part and the part lower, and receiving at least a part of the means for articulating such a support relative to the other support.

Ainsi, l'invention consiste en ce que chaque support comporte une partie intermédiaire recevant une partie des moyens pour articuler un support sur un autre support.Thus, the invention consists in that each support comprises an intermediate part receiving part of the means for articulating a support on another support.

Une telle caractéristique permet, avantageusement, d'incorporer une partie au moins du repose-pieds et une partie au moins d'au moins un garde-corps à l'intérieur de la structure constituée et délimitée par les deux supports. Ceci permet, également, de réduire la taille des éléments (repose-pieds, garde-corps) qui s'étendent latéralement par rapport aux supports. Il en résulte une amélioration substantielle de la compacité du dispositif, plus particulièrement de la profondeur de ce dispositif, ceci en position repliée de ce dispositif.Such a feature advantageously makes it possible to incorporate at least a portion of the footrest and at least a portion of at least one guardrail within the structure constituted and delimited by the two supports. This also makes it possible to reduce the size of the elements (footrest, railing) that extend laterally relative to the supports. This results in a substantial improvement in the compactness of the device, more particularly the depth of this device, in the folded position of this device.

Une telle caractéristique permet, également, de conférer aux deux supports d'un dispositif d'accès en hauteur une longueur sensiblement identique. Ceci permet, alors et avantageusement, de conférer aux deux éléments pour prolonger ces deux supports une longueur qui, là encore, peut être sensiblement identique, ceci sans que cette longueur soit limitée par le support le plus court comme pour les dispositifs de l'état de la technique.Such a characteristic also makes it possible to confer on the two supports of an access device at height a substantially identical length. This allows, then and advantageously, to give the two elements to extend these two supports a length which, again, can be substantially identical, this without this length being limited by the shortest support as for devices of the state of the technique.

Cette caractéristique permet, alors avantageusement, de positionner le repose-pied du dispositif selon l'invention à une altitude supérieure à celle permise par les dispositifs de l'état de la technique.This characteristic makes it possible, advantageously, to position the footrest of the device according to the invention at an altitude higher than that permitted by the devices of the state of the art.

De plus, le fait que chaque support comporte une partie intermédiaire recevant une partie des moyens d'articulation permet de conférer au dispositif une configuration en « X », ceci en position déployée de ce dispositif. Cette configuration permet de mettre à profit la partie supérieure des supports pour y implanter, de manière astucieuse et particulièrement avantageuse, au moins un garde corps.In addition, the fact that each support has an intermediate portion receiving a portion of the hinge means allows to confer the device an "X" configuration, this in the deployed position of this device. This configuration allows to take advantage of the upper part of the supports to implement, in a clever and particularly advantageous way, at least one railing.

D'autres buts et avantages de la présente invention apparaîtront au cours de la description qui va suivre se rapportant à des modes de réalisation qui ne sont donnés qu'à titre d'exemples indicatifs et non limitatifs.Other objects and advantages of the present invention will become apparent from the following description relating to embodiments which are given by way of indicative and non-limiting examples.

La présente invention concerne le domaine de la fabrication des dispositifs d'accès en hauteur de type repliable, plus particulièrement constitués par des plateformes, des marchepieds, des échelles ou analogue.The present invention relates to the field of manufacture of folding-type height access devices, more particularly constituted by platforms, steps, ladders or the like.

Un tel dispositif d'accès en hauteur 1 comporte deux supports (2 ; 2'), chacun s'étendant sensiblement dans un plan.Such a height access device 1 comprises two supports (2; 2 '), each extending substantially in one plane.

Un tel support (2 ; 2') comporte une partie supérieure (20 ; 20'), une partie inférieure (21 ; 21'), et une partie intermédiaire (22 ; 22') interposée entre la partie supérieure (20 ; 20') et la partie inférieure (21 ; 21') de ce support (2 ; 2').Such a support (2; 2 ') has an upper part (20; 20'), a lower part (21; 21 ') and an intermediate part (22; 22') interposed between the upper part (20; 20 '). ) and the lower part (21; 21 ') of this support (2; 2').

Un tel support (2 ; 2') comporte, également, deux montants parallèles (23 ; 23') et espacés l'un de l'autre, notamment constitués par des profilés.Such a support (2; 2 ') also comprises two parallel uprights (23; 23') and spaced apart from one another, in particular consisting of profiles.

Un tel support (2 ; 2') comporte, encore, des moyens (24 ; 24') pour raccorder entre eux les deux montants (23 ; 23') d'un tel support (2 ; 2'). De tels moyens (24 ; 24') pour raccorder peuvent, en particulier, être constitués par des traverses ou des barreaux dont une partie au moins peuvent constituer un échelon permettant à un opérateur de poser un pied pour gravir le dispositif d'accès en hauteur 1. Un tel support (2 ; 2') peut, alors, être au moins en partie constitué par une échelle ou analogue.Such a support (2; 2 ') further comprises means (24; 24') for connecting together the two uprights (23; 23 ') of such a support (2; 2'). Such means (24; 24 ') for connecting may, in particular, be constituted by crosspieces or bars of which at least a portion may constitute a step allowing an operator to place a foot to climb the access device at height Such a support (2; 2 ') can then be at least partly constituted by a ladder or the like.

Ce dispositif d'accès en hauteur 1 comporte, alors également, des moyens 3 pour articuler au moins un support 2 par rapport à l'autre support 2'.This height access device 1 comprises, then also, means 3 for articulating at least one support 2 relative to the other support 2 '.

En fait, ces moyens 3 pour articuler au moins un support 2 par rapport à l'autre support 2' sont, plus particulièrement, conçus pour articuler les montants 23 d'un tel support 2 par rapport aux montants 23' de l'autre support 2'.In fact, these means 3 for articulating at least one support 2 relative to the other support 2 'are, more particularly, designed to articulate the uprights 23 of such a support 2 relative to the uprights 23' of the other support 2 '.

Ces moyens 3 pour articuler permettent, alors, au dispositif 1 d'accès en hauteur d'être amené d'une position repliée (figure 3) dans laquelle ces deux supports (2 ; 2') s'étendent de manière sensiblement parallèle l'un 2 par rapport à l'autre 2' à une position dépliée (figures 1 et 2) dans laquelle ces supports (2 ; 2') forment un angle aigüe entre eux (2 ; 2'), et inversement.These means 3 for articulating allow, then, to the device 1 of access to height to be brought from a folded position ( figure 3 ) in which these two supports (2; 2 ') extend substantially parallel to each other 2' to an unfolded position ( figures 1 and 2 ) in which these supports (2; 2 ') form an acute angle between them (2; 2'), and vice versa.

Selon une autre caractéristique, ce dispositif d'accès en hauteur 1 peut comporter, de manière additionnelle (voire préférentielle), au moins un élément (4 ; 4'), équipant au moins un support (2 ; 2'), et conçu pour prolonger un tel support (2 ; 2') ainsi que des moyens (5 ; 5') pour monter un tel élément (4 ; 4') pour prolonger un tel support (2 ; 2') de manière mobile par rapport à ce support (2 ; 2'), ceci entre une position rétractée et une position déployée d'un tel élément (4 ; 4').According to another characteristic, this height access device 1 may comprise, in addition (or preferably), at least one element (4; 4 '), equipping at least one support (2; 2'), and designed to extending such a support (2; 2 ') as well as means (5; 5') for mounting such an element (4; 4 ') to extend such a support (2; 2') movably with respect thereto (2; 2 '), this between a retracted position and an extended position of such an element (4; 4').

A ce propos, on observera que, selon un mode particulier de réalisation non représenté, ce dispositif 1 comporte, d'une part, un unique élément 4, équipant un des supports (2 ; 2'), et conçu pour prolonger ce support 2 et, d'autre part, des moyens 5 pour monter un tel élément 4 pour prolonger un tel support 2 de manière mobile par rapport à ce support 2, ceci entre une position rétractée et une position déployée d'un tel élément 4. Un tel dispositif d'accès en hauteur 1 peut, alors, être constitué par une échelle ou analogue.In this regard, it will be observed that, according to a particular embodiment not shown, this device 1 comprises, on the one hand, a single element 4, equipping one of the supports (2; 2 '), and designed to extend this support 2 and, on the other hand, means 5 for mounting such an element 4 to extend such a support 2 movably relative to the support 2, this between a retracted position and an extended position of such an element 4. Such a height access device 1 can, then, be constituted by a ladder or the like.

Cependant et selon un mode préféré de réalisation illustré sur les figures en annexe, le dispositif 1 comporte deux éléments (4 ; 4'), chacun équipant un support (2 ; 2'), et conçus pour prolonger ces supports (2 ; 2') ainsi que des moyens (5 ; 5') pour monter les éléments (4 ; 4') pour prolonger les supports (2 ; 2') de manière mobile par rapport à ces supports (2 ; 2'), ceci entre une position rétractée et une position déployée de ces éléments (4 ; 4').However, according to a preferred embodiment illustrated in the appended figures, the device 1 comprises two elements (4; 4 '), each equipping a support (2; 2'), and designed to extend these supports (2; 2 '). ) as well as means (5; 5 ') for mounting the elements (4; 4') to extend the supports (2; 2 ') movably relative to these supports (2; 2'), this between a position retracted and an extended position of these elements (4; 4 ').

Un tel dispositif d'accès en hauteur 1 peut, alors, être constitué par une plateforme, un marchepied ou analogue.Such a height access device 1 can, then, be constituted by a platform, a step or the like.

Au moins un tel élément (4 ; 4') pour prolonger un support (2 ; 2') comporte deux montants (40 ; 40'), espacés l'un de l'autre, et pouvant s'étendre de manière parallèle, ceci sur une partie au moins de leur longueur. Au moins un tel élément (4 ; 4') comporte, également, des moyens (41 ; 41') conçus pour raccorder entre eux ses deux montants (40 ; 40'). Ces moyens pour raccorder (41 ; 41') peuvent être constitués par des traverses ou par des barreaux dont une partie au moins constitue un échelon permettant à un opérateur de poser un pied pour gravir le dispositif d'accès en hauteur 1. Un tel élément (4 ; 4') peut, alors, être au moins en partie constitué par une échelle ou analogue.At least one such element (4; 4 ') for extending a support (2; 2') comprises two uprights (40; 40 ') spaced apart from each other and extending parallel to each other; on at least part of their length. At least one such element (4; 4 ') also comprises means (41; 41') designed to connect together its two uprights (40; 40 '). These means for connecting (41; 41 ') may be constituted by crosspieces or bars, at least a portion of which constitutes a step allowing an operator to place a foot to climb the height access device 1. Such an element (4; 4 ') can then be at least partly constituted by a scale or the like.

Tel que mentionné ci-dessus, le dispositif 1 d'accès en hauteur comporte, également, des moyens (5 ; 5') pour monter un élément (4 ; 4') pour prolonger un support (2 ; 2') de manière mobile par rapport à ce support (2 ; 2'), ceci entre une position rétractée (figure 1 et 3) et une position déployée (figure 2) de cet élément (4 ; 4'), et inversement.As mentioned above, the height access device 1 also comprises means (5; 5 ') for mounting an element (4; 4') for extending a support (2; 2 ') in a mobile manner. relative to this support (2; 2 '), this enters a retracted position ( figure 1 and 3 ) and an extended position ( figure 2 ) of this element (4; 4 '), and vice versa.

De manière additionnelle, un tel dispositif d'accès en hauteur 1 comporte, encore, un repose-pied 6 s'étendant entre les deux supports (2 ; 2'). C'est, plus particulièrement, la partie inférieure (21 ; 21') d'un tel support (2 ; 2') qui reçoit, alors, au moins une partie (60 ; 60') d'un tel repose-pied 6.In addition, such a height access device 1 further includes a footrest 6 extending between the two supports (2; 2 '). It is, more particularly, the lower part (21; 21 ') of such a support (2; 2') which then receives at least a portion (60; 60 ') of such a footrest 6 .

Finalement, ce dispositif d'accès en hauteur 1 comporte au moins un garde corps (7 ; 8), plus particulièrement un garde corps inférieur 7 (usuellement dénommé lisse) et un garde corps supérieur 8 (usuellement dénommé sous-lisse). C'est, plus particulièrement, la partie supérieure (20 ; 20') d'un support (2 ; 2') qui reçoit, alors, au moins une partie (71, 71'; 81, 82, 82') d'au moins un tel garde corps (7 ; 8) comme il sera décrit ci-dessous.Finally, this height access device 1 comprises at least one guard (7; 8), more particularly a lower guard 7 (usually called smooth) and an upper guard 8 (usually called sub-smooth). It is, more particularly, the upper part (20; 20 ') of a support (2; 2') which then receives at least one part (71, 71 '; 81, 82, 82') of at least one such guard (7; 8) as will be described below.

Selon l'invention, chaque support (2 ; 2') comporte une partie supérieure (20 ; 20') recevant au moins une partie (71, 71'; 81, 82, 82') d'au moins un garde corps (7 ; 8), une partie inférieure (21 ; 21') recevant au moins une partie (60 ; 60') du repose-pied 6, et une partie intermédiaire (22 ; 22') recevant au moins une partie (30 ; 30') des moyens 3 pour articuler un tel support 2 par rapport à l'autre support 2'.According to the invention, each support (2; 2 ') comprises an upper part (20; 20') receiving at least one part (71, 71 '; 81, 82, 82') of at least one railing (7; 8), a lower portion (21; 21 ') receiving at least a portion (60; 60') of the footrest 6, and an intermediate portion (22; 22 ') receiving at least a portion (30; 30') ) means 3 for articulating such a support 2 relative to the other support 2 '.

Un tel mode de réalisation permet, avantageusement, de conférer au dispositif d'accès en hauteur 1 de l'invention une configuration en « X », ceci en position dépliée de ce dispositif 1.Such an embodiment advantageously makes it possible to confer on the height access device 1 of the invention an "X" configuration, in the unfolded position of this device 1.

Selon une autre caractéristique, les deux montants parallèles 23 d'un support 2 sont articulés entre les deux montants 23' parallèles de l'autre support 2'.According to another characteristic, the two parallel uprights 23 of a support 2 are articulated between the two parallel uprights 23 'of the other support 2'.

Une caractéristique additionnelle consiste en ce que les moyens 3 pour articuler un support 2 par rapport à l'autre support 2' sont conçus pour permettre, d'une part, un croisement des supports (2 ; 2') du dispositif 1 en position dépliée de ce dispositif 1 et, d'autre part, un positionnement parallèle des supports (2 ; 2') du dispositif 1 en position repliée de ce dispositif 1.An additional feature is that the means 3 for articulating a support 2 relative to the other support 2 'are designed to allow, on the one hand, a crossing of the supports (2; 2') of the device 1 in the unfolded position of this device 1 and, on the other hand, a parallel positioning of the supports (2; 2 ') of the device 1 in the folded position of this device 1.

Pour ce faire et étant donné que les supports (2 ; 2') s'étendent, chacun, dans un plan, les moyens 3 pour articuler sont conçus pour assurer une articulation selon un axe parallèle et décalé latéralement par rapport au plan d'extension d'au moins un support (2 ; 2'), de préférence par rapport aux plans d'extension de ces deux supports (2 ; 2').To do this and since the supports (2; 2 ') extend, each in a plane, the means 3 for articulating are designed to provide articulation along an axis parallel and offset laterally with respect to the extension plane at least one support (2; 2 '), preferably with respect to the extension planes of these two supports (2; 2').

En fait, les moyens 3 pour articuler un support 2 par rapport à l'autre support 2' comportent, d'une part, au moins une platine 30 fixée sur ce support 2, d'autre part, au moins une autre platine 30' fixée sur cet autre support 2' et, d'autre part encore, au moins un arbre 31 conçu pour raccorder la platine 30 du support 2 à la platine 30' de l'autre support 2', et sur lequel 31 au moins une telle platine (30 ; 30') est montée en rotation.In fact, the means 3 for articulating a support 2 relative to the other support 2 'comprise, on the one hand, at least one plate 30 fixed on the support 2, on the other hand, at least one other plate 30' fixed on this other support 2 'and, on the other hand, at least one shaft 31 designed to connect the plate 30 of the support 2 to the plate 30' of the other support 2 ', and on which 31 at least one such platen (30; 30 ') is rotatably mounted.

Selon un mode particulier de réalisation, les moyens 3 pour articuler un support 2 par rapport à l'autre support 2 comportent, en fait, d'une part, deux platines 30 fixées, chacune, sur un côté latéral externe 230 (respectivement interne) d'un montant 23 du support 2 et s'étendant latéralement par rapport au plan dans lequel s'étend ce support 2, d'autre part, deux autres platines 30' fixées, chacune, sur un côté latéral externe 230' (respectivement interne) d'un montant 23' de l'autre support 2' et s'étendant latéralement par rapport au plan dans lequel s'étend cet autre support 2' et, d'autre part encore, deux arbres 31, chacun pour raccorder la platine 30 d'un support 2 à l'autre platine 30' de l'autre support 2', et s'étendant de part et d'autre du montant 23' de cet autre support 2'.According to a particular embodiment, the means 3 for articulating a support 2 relative to the other support 2 comprise, in fact, on the one hand, two plates 30 fixed, each, on an external lateral side 230 (respectively internal) of an upright 23 of the support 2 and extending laterally with respect to the plane in which this support 2 extends, on the other hand, two other plates 30 'fixed, each, on an external lateral side 230' (respectively internal ) of an amount 23 'of the other support 2' and extending laterally relative to the plane in which this other support 2 'extends and, secondly, two shafts 31, each for connecting the plate 30 of a support 2 to the other plate 30 'of the other support 2', and extending on either side of the upright 23 'of the other support 2'.

Un tel mode de réalisation permet, alors, d'assurer un montage articulé des montants 23 d'un support 2 entre les montants 23' de l'autre support 2'.Such an embodiment then makes it possible to provide an articulated mounting of the uprights 23 of a support 2 between the uprights 23 'of the other support 2'.

Tel que mentionné ci-dessus, le dispositif d'accès en hauteur 1 comporte des moyens (5 ; 5') pour monter un élément (4 ; 4') pour prolonger un support (2 ; 2') de manière mobile par rapport à ce support (2 ; 2').As mentioned above, the height access device 1 comprises means (5; 5 ') for mounting an element (4; 4 ') for extending a support (2; 2') movably relative to this support (2; 2 ').

En fait, ces moyens (5 ; 5') pour monter comportent des moyens pour monter en coulissement au moins une partie (plus particulièrement une extrémité supérieure) d'un tel élément (4 ; 4') pour prolonger un support (2 ; 2'), ceci par rapport à ce support (2 ; 2'), plus particulièrement par rapport à un montant (23 ; 23') que comporte un tel support (2 ; 2') et de manière longitudinale par rapport à un tel montant (23 ; 23').In fact, these means (5; 5 ') for mounting comprise means for slidably mounting at least a portion (more particularly an upper end) of such an element (4; 4') to extend a support (2; '), this with respect to this support (2; 2'), more particularly with respect to an upright (23; 23 ') that includes such a support (2; 2') and longitudinally with respect to such amount (23; 23 ').

Selon un mode de réalisation préféré de l'invention, les moyens (5 ; 5') pour monter un élément (4 ; 4') pour prolonger un support (2 ; 2') de manière mobile par rapport à ce support (2 ; 2') comportent, d'une part, au moins une glissière (50 ; 50') que comporte ou qui est associée à ce support (2 ; 2') et, d'autre part, au moins un organe, engagé à l'intérieur d'une telle glissière (50 ; 50'), et que comporte un élément (4 ; 4') pour prolonger ce support (2 ; 2').According to a preferred embodiment of the invention, the means (5; 5 ') for mounting an element (4; 4') for extending a support (2; 2 ') movably relative to this support (2; 2 ') comprise, on the one hand, at least one slide (50; 50') that comprises or is associated with this support (2; 2 ') and, on the other hand, at least one member, engaged to the interior of such a slide (50; 50 '), and that comprises an element (4; 4') for extending this support (2; 2 ').

A ce propos, on observera que ces moyens (5 ; 5') pour monter comportent, en fait, deux glissières (50 ; 50'), chacune associé à un montant (23 ; 23') d'un support (2 ; 2').In this regard, it will be observed that these means (5; 5 ') for mounting comprise, in fact, two slides (50, 50'), each associated with an upright (23; 23 ') of a support (2; ').

Selon un premier mode de réalisation, chaque montant (23 ; 23') d'un support (2 ; 2') comporte une telle glissière (50 ; 50') qui peut, alors, être incorporée à un tel montant (23 ; 23') et/ou réalisée de matière avec un tel montant (23 ; 23').According to a first embodiment, each upright (23; 23 ') of a support (2; 2') comprises such a slide (50; 50 ') which can then be incorporated in such an upright (23; ') and / or made of material with such an amount (23; 23').

Cependant et selon un mode de réalisation illustré sur les figures en annexe, une telle glissière (50 ; 50') peut encore être associée à un montant (23 ; 23') d'un support (2 ; 2') et se présenter, alors, au moins en partie sous la forme d'un profilé fixé sur un tel montant (23 ; 23') et s'étendant de manière longitudinale le long de ce montant (23 ; 23'), notamment le long d'un champ de ce montant (23 ; 23').However, and according to one embodiment illustrated in the appended figures, such a slide (50; 50 ') can be associated with an upright (23; 23') of a support (2; 2 ') and present itself, then, at least partly in the form of a profile fixed on such an upright (23; 23 ') and extending longitudinally along this upright (23; 23'), in particular along a field of this amount (23; 23 ').

Ces moyens (5 ; 5') pour monter comportent, alors, également, deux organes, notamment sous forme d'un téton ou analogue, et que comporte un élément (4 ; 4'), plus particulièrement au niveau de son extrémité supérieure.These means (5; 5 ') for mounting also comprise two members, in particular in the form of a pin or the like, and which comprises an element (4; 4'), more particularly at its upper end.

Une caractéristique additionnelle consiste en ce que le dispositif d'accès en hauteur 1 comporte des moyens (9 ; 10) pour immobiliser un élément (4 ; 4') pour prolonger un support (2 ; 2') par rapport au support (2 ; 2') qu'il équipe, ceci en position déployée et/ou en position rétractée d'un tel élément (4 ; 4').An additional feature is that the height access device 1 comprises means (9; 10) for immobilizing an element (4; 4 ') to extend a support (2; 2') with respect to the support (2; 2 ') that it equips, in the deployed position and / or in the retracted position of such an element (4; 4').

Ainsi, ce dispositif 1 peut comporter des moyens 9 pour immobiliser un tel élément (4 ; 4') par rapport à un tel support (2 ; 2'), ceci en position déployée de cet élément (4 ; 4').Thus, this device 1 may comprise means 9 for immobilizing such an element (4; 4 ') relative to such a support (2; 2'), this in the deployed position of this element (4; 4 ').

Tel que visible sur la figure 6, de tels moyens 9 pour immobiliser un élément (4 ; 4') en position déployée comportent, d'une part, au moins un crochet d'accrochage 90 équipant au moins un support (2 ; 2') (plus particulièrement un montant 23 de ce support 2) et, d'autre part, au moins un organe 91, que comporte un élément (4 ; 4') pour prolonger ce support (2 ; 2'), et qui est conçu pour coopérer avec le crochet d'accrochage 90.As visible on the figure 6 such means 9 for immobilizing an element (4; 4 ') in the deployed position comprise, on the one hand, at least one hook hook 90 equipping at least one support (2; 2') (more particularly an upright 23 of this support 2) and, on the other hand, at least one member 91, which comprises an element (4; 4 ') for extending this support (2; 2'), and which is designed to cooperate with the hook of hanging 90.

En ce qui concerne ledit organe 91, celui-ci peut être constitué par une traverse ou un barreau (plus particulièrement qui s'étend entre deux montants 23 d'un support 2, qui raccorde ces deux montants 23, et/ou qui constitue un échelon) ou par un plot (plus particulièrement qui équipe latéralement un montant 23 d'un support 2).With regard to said member 91, it may be constituted by a crossbar or a bar (more particularly which extends between two uprights 23 of a support 2, which connects these two uprights 23, and / or which constitutes a echelon) or by a stud (more particularly which equips laterally an amount 23 of a support 2).

En fait, un tel plot est ménagé en partie supérieure d'un élément (4 ; 4') pour prolonger un support (2 ; 2') et permet, avantageusement, de ménager un passage entre les montants ((40 ; 40') de cet élément (4 ; 4') afin de pouvoir accéder au repose-pied 6 sans entrave, ceci en position partiellement déployée ou partiellement rétractée (figures 1) de cet élément (4 ; 4).In fact, such a stud is formed in the upper part of an element (4; 4 ') to extend a support (2; 2') and advantageously allows to provide a passage between the uprights ((40; 40 ') of this element (4; 4 ') in order to be able to access the footrest 6 without hindrance, this in the partially deployed or partially retracted position ( figures 1 ) of this element (4; 4).

La coopération entre le crochet d'accrochage 90 et un tel plot est, en particulier, assurée en position intégralement déployée de l'élément (4 ; 4') pour prolonger un support (2 ; 2').The cooperation between the hooking hook 90 and such a stud is, in particular, provided in the fully extended position of the element (4; 4 ') to extend a support (2; 2').

De manière alternative ou complémentaire, ce dispositif 1 peut comporter des moyens 10 pour immobiliser un tel élément (4 ; 4') par rapport à un tel support (2 ; 2'), ceci en position rétractée de cet élément (4 ; 4').Alternatively or additionally, this device 1 may comprise means 10 for immobilizing such an element (4; 4 ') with respect to such a support (2; 2'), in the retracted position of this element (4; 4 '). ).

En fait, ces moyens de réception 101 adoptent, plus particulièrement, la forme d'une découpe ménagée dans une portion de plinthe 61 que comportent la première 60 et/ou la deuxième 60' partie de ce repose-pied 6.In fact, these receiving means 101 adopt, more particularly, the shape of a cutout formed in a skirting portion 61 that includes the first 60 and / or the second 60 'part of this footrest 6.

Tel que mentionné ci-dessus, le dispositif d'accès en hauteur 1 comporte au moins un garde corps (7 ; 8).As mentioned above, the height access device 1 comprises at least one guard (7; 8).

En particulier, ce dispositif 1 comporte un garde corps inférieur 7 (usuellement dénommé sous-lisse) adoptant la forme d'un cadre 70 comportant, d'une part, une première partie 71 de cadre 70, équipant latéralement un support 2, adoptant une forme en « U », et au moins en partie constituée par une partie d'un portillon 11 refermant ce garde corps inférieur 7.In particular, this device 1 comprises a lower guard 7 (usually called sub-smooth) adopting the shape of a frame 70 comprising, on the one hand, a first portion 71 of frame 70, fitted laterally a support 2, adopting a "U" shape, and at least partly formed by a portion of a gate 11 closing the lower body guard 7.

Tel que visible sur la figure 7, cette première partie 71 de cadre 70 comporte deux pièces parallèles 710 s'étendant latéralement à partir du support 2 ainsi qu'une pièce transversale 711, raccordant les deux pièces parallèles 710 (plus particulièrement les extrémités libres de ces deux pièces parallèles 710), montée en rotation sur l'une de ces pièces parallèles 710, et constituant une partie d'un portillon 11 refermant le garde corps inférieur 7.As visible on the figure 7 this first part 71 of frame 70 comprises two parallel parts 710 extending laterally from the support 2 and a transverse part 711, connecting the two parallel parts 710 (more particularly the free ends of these two parallel parts 710), mounted in rotation on one of these parallel parts 710, and constituting part of a gate 11 closing the lower guard 7.

En fait, ces deux pièces parallèles 710 sont fixes par rapport au support 2 qu'elles équipent et équipent, chacune, un montant 23 de ce support 2, plus particulièrement un champ que comporte un tel montant 23.In fact, these two parallel parts 710 are fixed relative to the support 2 which they equip and equip, each, an amount 23 of this support 2, more particularly a field that includes such a post 23.

De plus, le dispositif 1 peut, encore, comporter des montants (verticaux en position dépliée de ce dispositif 1) permettant de raccorder l'extrémité libre de ces deux pièces parallèles 710 à la partie supérieure 20 d'un support 2.In addition, the device 1 may also comprise uprights (vertical in unfolded position of this device 1) for connecting the free end of these two parallel parts 710 to the upper part 20 of a support 2.

On observera que cette première partie 71 de cadre 70 que comporte un support 2 et l'élément 4' pour prolonger l'autre support 2' sont dimensionnés et/ou configurés en sorte que cette première partie 71 de cadre 70 reçoive, extérieurement, cet élément 4' pour prolonger cet autre support 2', ceci en position rétractée de cet élément 4'. Cette première partie 71 de cadre 70 vient, alors, se positionner entre les montants 40' de cet élément 4' rétracté.It will be observed that this first part 71 of frame 70 that comprises a support 2 and the element 4 'to extend the other support 2' are dimensioned and / or configured so that this first part 71 of frame 70 receives, externally, this element 4 'to extend this other support 2', in the retracted position of this element 4 '. This first portion 71 of frame 70 then comes to be positioned between the uprights 40 'of this element 4' retracted.

D'autre part, ce cadre 70 comporte une deuxième partie 71' de cadre 70, constituée par une pièce en «U », et équipant latéralement l'autre support 2'.On the other hand, this frame 70 has a second portion 71 'of frame 70, constituted by a piece "U", and laterally fitting the other support 2'.

Une telle pièce en « U » est fixe par rapport à cet autre support 2' et est constituée par profilé plié ou par assemblage de profilés.Such a piece "U" is fixed relative to the other support 2 'and is formed by folded section or by joining profiles.
