Description

L'invention concerne un dispositif permettant de fixer des accessoires sur une échelle.The invention relates to a device for fixing accessories on a ladder.

Les accessoires à fixer sur les échelles sont bien connus. Ils consistent par exemple en des pièces de crochets, de coulisse, d'articulation... servant à l'accouplement d'échelles ou de support d'outillage ou d'objets pour l'utilisateur.The accessories to be fixed on the ladders are well known. They consist, for example, of parts of hooks, of slides, of articulation ... used for the coupling of ladders or of tool or object support for the user.

Les pièces accessoires sont généralement fixées aux montants d'echelle directement par vissage, rivetage, soudage sur le montant ou par emboîtement dans l'extrémité des montants ou encore enfilage sur l'échelon.The accessory parts are generally fixed to the ladder uprights directly by screwing, riveting, welding on the upright or by fitting in the end of the uprights or even threading on the rung.

L'objet de l'invention est de réaliser une fixation des accessoires d'échelle qui soit rigide 'et qui puisse être effectuée à une hauteur variable et réglable de l'échelle par l'utilisateur.The object of the invention is to provide a fixing of the ladder accessories which is rigid and which can be carried out at a variable and adjustable height of the ladder by the user.

Il est en effet proposé selon l'invention un dispositif de fixation d'accessoires pour échelle, caractérisé en ce qu'il fait intervenir au moins un élément de coulisse fixé longitudinalement sur un montant d'échelle, et des accessoires divers pour échelles conformés pour coulisser par leur base sur ledit élément de coulisse, lesdits accessoires étant aptes à être fixés à hauteur d'utilisation désirée sur ledit élément de coulisse par un moyen mécanique classique de fixation, éventuellement déverrouillable, telle qu'une butée escamotable en prise sur un crantage du montant,un point de soudure, une déformation locale, la pose d'une vis, d'un rivet etc..It is in fact proposed according to the invention a device for attaching accessories to a ladder, characterized in that it involves at least one slide element fixed longitudinally on a ladder upright, and various accessories for ladders shaped to slide by their base on said slide element, said accessories being able to be fixed at the desired height of use on said slide element by conventional mechanical fixing means, optionally unlockable, such as a retractable stop engaged in a catch of the upright, a welding point, a local deformation, the installation of a screw, a rivet etc.

Cette disposition, outre qu'elle autorise un positionnement variable en hauteur des accessoires sur l'élément de coulisse, permet également de rendre les accessoires indépendants des diverses gammes d'échelles pour lesquelles ils étaient jusqu'à maintenant spécifiquement conformés.This arrangement, in addition to allowing variable positioning in height of the accessories on the slide element, also makes it possible to make the accessories independent of the various ranges of scales for which they have until now been specifically shaped.

Des accessoires standards peuvent donc être utilisés avec les diverses gammes d'échelles équipées du dispositif de fixation selon l'invention.Standard accessories can therefore be used with the various ranges of ladders fitted with the fixing device according to the invention.

Le dispositif de fixation d'accessoires selon l'invention fait avantageusement intervenir deux éléments de coulisse par montant, ces éléments étant de la hauteur des montants et disposés opposés sur les montants, respectivement sur les faces supérieure et inférieure du montant relativement à l'utilisateur. Les éléments de coulisse peuvent avoir un profil à deux ailes externes opposées. La face externe du profil peut avoir une configuration arrondie favorable à la préhension de l'échelle. De préférence, ces profils de coulisse possèdent une symétrie par rapport à un plan longitudinal médian.The accessory fixing device according to the invention advantageously involves two slide elements per upright, these elements being the height of the uprights and arranged opposite on the uprights, respectively on the upper and lower faces of the upright relative to the user . The sliding elements can have a profile with two opposite external wings. The external face of the profile can have a rounded configuration favorable to gripping the ladder. Preferably, these slide profiles have symmetry with respect to a median longitudinal plane.

Cette disposition contribue par ailleurs à améliorer la rigidité des échelles équipées.This arrangement also contributes to improving the rigidity of the fitted ladders.

Naturellement, si la section des montants d'échelle est rectangulaire -c'est le cas le plus usité-, les éléments de coulisse seront montés sur les petits côtés du rectangle, formant respectivement les faces supérieure et inférieure du montant relativement à l'utilisateur.Naturally, if the section of the ladder uprights is rectangular - this is the most common case -, the sliding elements will be mounted on the short sides of the rectangle, respectively forming the upper and lower faces of the upright relative to the user. .

En outre, les éléments de coulisse pouront être issus de fabrication avec le montant, par exemple par moulage, extrusion de matière ou autre.In addition, the slide elements can be obtained from manufacturing with the upright, for example by molding, extrusion of material or the like.

L'invention concerne également les échelles obtenues ainsi que les accessoires adaptés correspondants.The invention also relates to the scales obtained and the corresponding suitable accessories.

L'invention est illustrée ci-après à l'aide d'exemples de réalisation et en référence aux dessins annexés sur lesquels :

  • La figure 1 est une vue éclatée en coupe transversale d'un montant d'échelle équipé d'un dispositif de fixation selon l'invention, et de la base de fixation d'un accessoire adapté correspondant ;
  • Les figures 2 à 6 montrent divers accessoires selon l'invention ;
  • La figure 7 est une vue de deux échelles accouplées longitudinalement et équipées de dispositifs de fixation d'accessoires selon l'invention et de divers accessoires adaptés;
  • La figure 8 est une vue de deux échelles accouplées en V, équipées de dispositifs de fixation d'accessoires selon l'invention et de divers accessoires adaptés ; et
  • Les figures 9a et 9b; 10a et 10b; 11a et 11b, sont des vues agrandies de ces accessoires en élévation et en coupe, ou de dessus, respectivement du manchon d'accouplement, du pied coulissant, des accessoires d'articulation supérieures et des bras d'écartement.
The invention is illustrated below with the aid of exemplary embodiments and with reference to the appended drawings in which:
  • Figure 1 is an exploded view in cross section of a ladder upright equipped with a fixing device according to the invention, and the fixing base of a corresponding suitable accessory;
  • Figures 2 to 6 show various accessories according to the invention;
  • Figure 7 is a view of two ladders coupled longitudinally and equipped with accessory fixing devices according to the invention and various suitable accessories;
  • Figure 8 is a view of two coupled ladders V-shaped, equipped with accessory fixing devices according to the invention and various suitable accessories; and
  • Figures 9a and 9b; 10a and 10b; 11a and 11b are enlarged views of these accessories in elevation and in section, or from above, respectively of the coupling sleeve, of the sliding foot, of the upper articulation accessories and of the spacer arms.

La figure 1 représente un montant d'échelle 1 selon l'invention et un accessoire correspondant représenté partiellement et destiné à être monté sur cette échelle. Seule, la base de fixation 5 de l'accessoire au montant a été représentée, la partie supérieure 7 représentée partiellement correspondant à la partie fonctionnelle classique de l'accessoire. Cette partie peut consister, par exemple, en un élément de glissière pour échelle (figure 2), d'articulation ou d'attache de rembarde (figure 3), un élément d'extrémité d'échelle transformable (figure 4), un élément de crochet (en prise sur les échelons) (figure 5) ou encore en un élément de butée pour l'accrochage d'objets (figure 6) etc...FIG. 1 represents a ladder upright 1 according to the invention and a corresponding accessory shown partially and intended to be mounted on this ladder. Only the attachment base 5 of the accessory to the upright has been shown, the upper part 7 shown partially corresponding to the conventional functional part of the accessory. This part may consist, for example, of a ladder slide element (Figure 2), hinge or pad attachment (Figure 3), a transformable ladder end element (Figure 4), an element hook (engaged on the rungs) (figure 5) or in a stop element for hanging objects (figure 6) etc ...

L'échelle selon l'invention comporte deux montants identiques 1 issus d'extrusion en alliage d'aluminium (dont un seul est représenté). Ces montants sont reliés par des échelons ou barreaux 9. Les montants sont de section à forme générale rectangulaire. Les petits côtés opposés du rectangle sont conformés chacun avec deux ailes externes 11 profilées longitudinalement dont le bord supérieur 13 est arrondi et dont la surface intérieure 15 (horizontale) est plane, ces ailes définissant un profil de glissière pour les accessoires dont la base 5 est conformée en creux de façon complémentaire et à faible jeu. L'ensemble est formé avec symétrie par rapport à un plan vertical longitudinal médian du montant (trait mixte). L'accessoire est donc reçu coulissant à faible jeu par le profil de glissière du montant, sur sa hauteur et avec possibilité de montage sur un petit côté ou l'autre du montant.The ladder according to the invention comprises two identical uprights 1 obtained from aluminum alloy extrusion (only one of which is shown). These uprights are connected by rungs or bars 9. The uprights are of generally rectangular section. The opposite small sides of the rectangle are each shaped with two longitudinally profiled outer wings 11 whose upper edge 13 is rounded and whose inner surface 15 (horizontal) is flat, these wings defining a slide profile for the accessories whose base 5 is hollowed out in a complementary manner and with little play. The assembly is formed symmetrically with respect to a vertical longitudinal median plane of the upright (mixed line). The accessory is therefore received sliding with little play by the profile of the upright, on its height and with the possibility of mounting on a small side or the other of the upright.

L'accessoire est monté sur sa glissière depuis l'extrémité du montant sur le petit côté du montant souhaité puis déplacé en coulissement sur le montant jusqu'à la hauteur d'utilisation désirée. Ensuite, il est fixé en position à cette hauteur par un moyen de fixation classique, tel qu'une vis appliquée sur la partie médiane de la base de l'accessoire (figure 4) ou sur sa partie latérale verticale (figure 3) et en prise dans le montant.The accessory is mounted on its slide from the end of the upright on the short side of the desired upright and then moved slidingly on the upright to the desired height of use. Then, it is fixed in position at this height by a conventional fixing means, such as a screw applied to the middle part of the base of the accessory (FIG. 4) or to its vertical lateral part (FIG. 3) and in taken in the amount.

Du fait que ces moyens de fixation travaillent essentiellement en cisaillement, ils n'ont pas besoin d'être d'une grande résistance. Des moyens de fixation rapide peuvent être utilisés, tels que des rivets aveugles à montage rapide. Des moyens de butée escamotable automatique, fonctionnant par exemple par serrage sur les ailes du montant ou sur un crantage adéquate formé sur le montant peuvent également être utilisés. On obtient alors un déplacement facile et rapide de l'accessoire sur le montant.Because these fixing means work essentially in shear, they do not need to be of great resistance. Quick fasteners can be used, such as quick-mount blind rivets. Automatic retractable stop means, operating for example by clamping on the wings of the upright or on a suitable notch formed on the upright can also be used. This gives an easy and quick movement of the accessory on the upright.

On a représenté sur la figure 7 un exemple d'accouplement longitudinal de deux échelles simples selon l'invention. Ces échelles ont été réunies bout à bout par quatre pièces de manchons 17 (figures 9a, 9b) identiques enfilées sur une partie des montants profilés des échelles. Ces pièces de manchon sont conformées chacune avec deux rainures de coulissement opposées 19 prévues pour coopérer avec les ailes de coulisse des deux petits côtés du montant. Elles sont vérouillées en position sur les montants à l'aide d'éléments de fixation classiques, telle que des vis 21 fixées latéralement aux montants ou une déformation de matière locale formant butée de déplacement du manchon sur la longueur des montants. Ces pièces de manchon peuvent en outre être conformées avec une certaine longueur, sans être limitées par l'emplacement des échelons comme dans les manchons classiques, de sorte qu'ils sont à même de supporter la rigidité nécessaire à la partie médiane de l'ensemble des deux échelles accouplées, notamment lorsque les échelles sont longues.FIG. 7 shows an example of a longitudinal coupling of two simple scales according to the invention. These scales were joined end to end by four identical pieces of sleeves 17 (FIGS. 9a, 9b) threaded over part of the profiled uprights of the scales. These sleeve parts are each shaped with two opposite sliding grooves 19 provided to cooperate with the sliding wings on the two short sides of the upright. They are locked in position on the uprights using conventional fasteners, such as screws 21 fixed laterally to the uprights or a deformation of local material forming a displacement stop for the sleeve over the length of the uprights. These sleeve pieces can also be shaped with a certain length, without being limited by the location of the rungs as in conventional sleeves, so that they are able to withstand the rigidity necessary for the middle part of the assembly. of the two coupled scales, especially when the scales are long.

Un pied 23 (figures 10a, 10b) pour s'adapter au dénivelé du terrain est monté à la partie inférieure de l'échelle inférieure. Les pieds classiques sont montés sur un support intermédiaire fixé au montant. Ici, le pied étant conformé selon une profilé apte à coulisser sur les ailes du montant, cette pièce support intermédiaire est inutile. Le réglage de hauteur pourra être effectué en arrêtant le pied en coulissement à une hauteur grossière désirée, par exemple en serrant une molette latérale 25 en prise sur des trous préformés à intervalles réguliers sur le montant puis en actionnant un vérin à vis d'extrémité 27 pour obtenir un réglage fin.A foot 23 (Figures 10a, 10b) to adapt to the elevation of the terrain is mounted at the bottom of the lower ladder. The classic feet are mounted on an intermediate support fixed to the upright. Here, the foot being shaped according to a profile capable of sliding on the wings of the upright, this intermediate support piece is unnecessary. The height adjustment can be carried out by stopping the sliding foot at a desired coarse height, for example by tightening a side wheel 25 engaged on preformed holes at regular intervals on the upright then by actuating an end screw jack 27 to obtain a fine adjustment.

Un accouplement en V d'échelles simples selon l'invention est représenté à la figure 8. Cet accouplement est réalisé à l'aide d'accessoires d'articulation 29 (figure 11a et 11b) fixés aux extrémités supérieures des éléments de coulisse des montants d'échelle et de bras d'écartement 31 reliés sensiblement à la partie médiane des échelles. Des pieds latéraux 33 sont en outre montés à la partie inférieure de l'une des échelles pour améliorer la stabilité de l'accouplement. Les bras d'écartement 31 sont fixés aux montants par des pièces à hase à forme de mâchoire identiques aux accessoires d'articulation et montées et fixées à hauteur déterminée sur l'élément de coulisse intérieur des montants d'échelle. Les pieds latéraux de stabilité 33 peuvent être réglés sur le site en jouant sur le coulissement des mâchoires support solidaires des éléments de coulisse à la partie inférieure des montants de l'échelle concernée.A V-shaped coupling of simple ladders according to the invention is shown in FIG. 8. This coupling is carried out using articulation accessories 29 (FIG. 11a and 11b) fixed to the upper ends of the sliding elements of the uprights. ladder and spacer arm 31 connected substantially to the middle part of the scales. Side legs 33 are further mounted at the bottom of one of the scales to improve the stability of the coupling. The spacer arms 31 are fixed to the uprights by jaw-shaped parts identical to the articulation accessories and mounted and fixed at a fixed height on the inner slide element of the ladder uprights. The lateral stability feet 33 can be adjusted on site by adjusting the sliding of the support jaws integral with the sliding elements at the bottom of the uprights of the ladder concerned.

Enfin, un plan de travail ou d'appui 35 a été monté sur l'une des échelles.Ce plan sera également fixé aux montants par l'intermédiaire de mâchoires reçues sur l'un ou les deux éléments de coulisses opposés des montants. Ces mâchoires pourront coulisser sur les montants pour s'adapter à la hauteur désirée du plan et être fixées à position par un moyen de serrage automatique sur les ailes des profilés du montant.Finally, a work or support plan 35 has been mounted on one of the scales. This plan will also be fixed to the uprights by means of jaws received on one or both of the opposite sliding elements of the uprights. These jaws can slide on the uprights to adapt to the desired height of the plane and be fixed in position by an automatic clamping means on the wings of the profiles of the upright.

Par ailleurs, d'autres accessoires, pour divers usages, adaptés au montage sur les éléments de coulisse peuvent être imaginés, tels que de petites pièces à forme de patin en matière plastique, conformées pour être clipsées de façon rapide et directe sur les éléments de coulisse des montants et constituer des éléments amortisseurs intermédiaires lorsque les échelles sont transportées repliées sur les barres des galeries de voiture.In addition, other accessories, for various uses, suitable for mounting on the sliding elements can be imagined, such as small parts in the form of a plastic shoe, shaped to be clipped quickly and directly onto the sliding elements of the uprights and constitute intermediate damping elements when the ladders are transported folded over the bars of the car galleries.

On notera de plus que l'invention n'est pas limitée au profil particulier de coulisse décrit dans l'exemple et qu'elle comprend toutes les variantes de réalisation imaginables dans le cadre des revendications ci-après.It will also be noted that the invention is not limited to the particular profile of the slide described in the example and that it includes all the variant embodiments imaginable within the scope of the claims below.
