Abstract
Description
La présente invention concerne un dispositif rendant possibleThe present invention relates to a device making it possible
l'utilisation sans risque d'une échelle dans un escalier, the safe use of a ladder in a staircase,
perpendiculairement aux marches.perpendicular to the steps.
L'accès aux parois d'un escalier le plus souvent étroit est difficile avec les outils habituels. En particulier l'utilisation d'une échelle perpendiculairement aux marches n'est pas aisée. On utilise alors des montages peu surs comme par exemple des cales pour rattraper la différence de marche. Ou on a recours à des échafaudages plus ou moins lourds. Access to the walls of a staircase usually narrow is difficult with the usual tools. In particular the use of a ladder perpendicular to the steps is not easy. We then use insecure assemblies such as shims to make up the difference in market. Or we resort to scaffolding more or less heavy.
Le dispositif selon l'invention permet d'apporter une solution simple à ce problème. Il comporte en effet selon une première caractéristique un étrier métallique en forme de U fixé sur un des pieds de l'échelle par un boulon, avec, traversant les deux cotés du U une tige filetée dont on peut ajuster la position. Ainsi la longueur utile de la tige permet de compenser la différence de marche, tandis que la rotation autour du boulon de fixation permet d'assurer à la tige la perpendicularité par rapport au sol. The device according to the invention makes it possible to provide a simple solution to this problem. It comprises in fact according to a first feature a U-shaped metal stirrup fixed on one of the feet of the ladder by a bolt, with, passing through both sides of the U a threaded rod whose position can be adjusted. Thus the useful length of the rod makes it possible to compensate for the difference in operation, while the rotation around the fixing bolt makes it possible to ensure the rod perpendicularity with respect to the ground.
Selon une deuxième caractéristique le dispositif comporte un étrier métallique de sécurité en forme de U assujetti à l'étrier précédent par un axe avec ses cotés dirigés vers l'échelle; ces cotés sont munis de trous filetés où sont placées deux vis de blocage. Cet étrier est maintenu perpendiculaire au bras d'échelle, et les deux vis serrées. Ainsi la rotation autour du boulon de fixation est bloquée. According to a second characteristic, the device comprises a U-shaped metal safety stirrup secured to the preceding stirrup by an axis with its sides directed towards the ladder; these sides are equipped with threaded holes where are placed two locking screws. This stirrup is held perpendicular to the ladder arm, and the two screws tight. Thus the rotation around the fixing bolt is blocked.
Selon les modes particuliers de fabrication le U de fixation peut être 25 plié à partir d'un fer plat, forgé ou découpé dans un profilé : -Une entretoise peut venir renforcer le U de fixation lors de l'ajustement de la tige filetée. According to the particular modes of manufacture, the fastening U may be bent from a flat iron, forged or cut into a profile: A spacer may strengthen the fastening U when adjusting the threaded rod.
- Un tube de renfort peut être placé sur la partie basse de la tige filetée. - A reinforcing tube can be placed on the lower part of the threaded rod.
-Une pastille plastique peut être mise sous l'embase pour protéger l'escalier. - A plastic tablet can be put under the base to protect the staircase.
Les dessins annexés illustrent l'invention. The accompanying drawings illustrate the invention.
La figure 1 représente le dispositif 2 monté sur une échelle 1 dans un escalier. Figure 1 shows the device 2 mounted on a scale 1 in a staircase.
La figure 2 représente le dispositif 2 de l'invention La figure 3 représente en coupe une réalisation artisanale de ce dispositif. FIG. 2 shows the device 2 of the invention. FIG. 3 is a sectional view of an artisanal embodiment of this device.
En référence à ces dessins le dispositif comporte un étrier de fixation F en forme de U en métal de dimensions appropriées pour résister à l'effort demandé. Cette pièce est percée de deux trous sur sa partie longue: Un pour le boulon de fixation B et un pour l'axe de rotation C de l'étrier de sécuritéS. Sur les cotés du U de l'étrier F on a percé d'un coté un trou T du diamètre de la tige filetée et de l'autre on a aménagé un filetage D correspondant à celui de la tige. With reference to these drawings, the device comprises a metal U-shaped fixing bracket F of appropriate dimensions to withstand the effort required. This piece is pierced with two holes on its long part: one for the fixing bolt B and one for the axis of rotation C of the safety stirrup. On the sides of the U of the stirrup F was drilled on one side a hole T of the diameter of the threaded rod and the other was arranged a thread D corresponding to that of the rod.
2885643 -2 Une tige filetée A de longueur suffisante pour compenser l'épaisseur d'une marche d'escalier plus 2 fois la longueur de l'étrier de fixation F, est vissée dans l'étrier de fixation F. Un écrou V vient bloquer la position de la tige A. On donnera à l'une des extrémités de la tige A une forme propre à entraîner sa rotation pour le réglage de la hauteur. L'autre extrémité est munie d'un sabot P propre à assurer une bonne assise de la béquille. Il peut être brasé, soudé, serti, vissé, ou enfoncé à force. 2885643 -2 A threaded rod A of sufficient length to compensate for the thickness of a stair step plus 2 times the length of the fixing bracket F, is screwed into the fixing bracket F. A V-nut locks the position of the rod A. One end of the rod A will be given a shape to cause its rotation to adjust the height. The other end is provided with a shoe P clean to ensure proper seating of the stand. It can be brazed, welded, crimped, screwed, or pressed down.
Un étrier de sécurité S en forme de U en métal de dimensions appropriées pour résister à l'effort demandé. Il s'agit pour cet élément de bloquer l'étrier de fixation F dans la position verticale par rapport au sol. Dans le centre de la partie longue du U, il est muni d'un axe C de façon à rester perpendiculaire au bras d'échelle. Sur les cotés du U on a aménagé deux filetages pour des vis P qui vont permettre de fixer cette position sur le bras d'échelle. A metal U-shaped safety stirrup of appropriate dimensions to withstand the effort required. It is for this element to lock the mounting bracket F in the vertical position relative to the ground. In the center of the long part of the U, it is provided with a C axis so as to remain perpendicular to the scale arm. On the sides of the U there are two threads for screws P which will allow to fix this position on the ladder arm.
L'échelle 1 peut être en métal plein ou creux, ou en bois. Il suffit qu'elle soit percée du trou correspondant au boulon de fixation, à une distance supérieure à la demi-longueur de l'étrier de fixation F à partir du pied d'échelle. The ladder 1 can be solid metal or hollow, or wood. It is sufficient that it is pierced by the hole corresponding to the fixing bolt, at a distance greater than the half-length of the fixing bracket F from the ladder foot.
A titre d'exemple non limitatif, la figure 3 montre le dispositif réalisé de façon artisanale. L'étrier de fixation F est formé à partir d'un fer plat de 5X40. Le boulon de fixation est de diamètre (D12. Le serrage était suffisant pour ne pas mettre l'étrier de sécurité. Une charge de 100kg a été mise sur l'échelle pour un test positif. By way of non-limiting example, Figure 3 shows the device made by hand. Fixing bracket F is formed from a 5X40 flat iron. The fixing bolt is of diameter (D12) The tightening was sufficient not to put the safety stirrup A load of 100kg was put on the scale for a positive test.
Les matériaux sont choisis pour offrir une résistance au moins égale à celle auquel correspond l'usage de l'échelle définie par le constructeur. L'échelle peut être en alu ou en bois. A titre d'exemple il suffit que l'on puisse percer un trou de diamètrel2 à une dizaine de cm du pied. Cette dimension n'est pas impérative, elle dépend de la taille de l'étrier choisi. The materials are chosen to offer a resistance at least equal to that which corresponds to the use of the scale defined by the manufacturer. The ladder can be aluminum or wood. For example, it is sufficient that one can drill a hole of diametre2 to about ten cm of the foot. This dimension is not imperative, it depends on the size of the chosen stirrup.
Le dispositif suivant l'invention est particulièrement destiné à l'utilisation d'une échelle dans un escalier que ce soit à titre domestique ou professionnel. The device according to the invention is particularly intended for the use of a ladder in a staircase whether for domestic or professional use.
