Abstract
Description
-1- La présente invention concerne un dispositif permettant d'augmenter laThe present invention relates to a device for increasing the
surface de contact entre une échelle à barreaux, en aluminium à un ou plusieurs plans, et un cyprès (cupressus sempervirens) afin d'accroître la stabilité de l'échelle. contact area between a bar ladder, aluminum with one or more planes, and a cypress (cupressus sempervirens) to increase the stability of the ladder.
Lors de la taille d'un cyprès en forme de "bougie", la surface de contact entre le barreau de l'échelle et le feuillage reste très faible, ce qui provoque une très forte instabilité, et par conséquence de grands risques de chutes. Aussi, l'échelle, sous le poids d'une personne, s'enfonce 10 dans le feuillage en l'écrasant et le déformant, empêchant le jardinier de réaliser correctement son travail. Le dispositif selon l'invention permet de remédier à ces :_nconvénients. Il est composé d'une partie en aluminium (que l'on nommera corps de l'appareil), de deux crochets possédant 15 chacun à leur extrémité un filetage afin de recevoir une molette de serrage. La gouttière du corps de l'appareil et les deux crochets emprisonnent deux barreaux d'une échelle, exerçant une pression à la manière d'une "mâchoire", lors du serrage des mollettes. When cutting a cypress shaped "candle", the contact area between the bar of the ladder and the foliage remains very low, which causes a very high instability, and therefore high risk of falls. Also, the ladder, under the weight of a person, sinks into the foliage crushing and deforming it, preventing the gardener from doing his job properly. The device according to the invention makes it possible to remedy these disadvantages. It is composed of an aluminum part (which will be called body of the apparatus), two hooks each having at their end a thread to receive a clamping wheel. The gutter of the body of the apparatus and the two hooks trap two bars of a ladder, exerting a pressure in the manner of a "jaw", when tightening the knobs.
20 Les dimensions du dispositif sont telles, qu'elles s'adaptent à toutes les échelles "standard" répondant aux normes françaises. A l'extrémité du corps de l'appareil se trouve un bandeau concave qui épouse la forme du cyprès lors de la pose d'une 25 échelle pourvue de ce dispositif. En effet, le feuillage n'est que très légèrement écrasé et déformé, tandis que la surface de contact est augmentée. Dans ce contexte, nous avons une excellente stabilité de L'échelle, les dessins annexés illustrent l'invention. 30 - la figure 1 représente en coupe le dispositif de l'invention. - La figure 2 représente une vue de dessus du dispositif. -2 En référence à ces dessins, le dispositif comporte une partie en aluminium (corps) constitué d'un bandeau concave (1) et d'une gouttière renversée (2), et de deux crochets en acier inoxydable (3) pourvus à leur extrémité d'un filetage recevant chacun une molette de serrage (4). La partie longue d'un crochet se loge dans deux orifices (5) situés dans la gouttière du corps de l'appareil qui comporte au total quatre trous. Lorsque les crochets sont positionnés les molettes de serrage 10 se vissent sur leur filetage. L'ensemble gouttière-crochets emprisonne deux barreaux d'une échelle (6), exerçant une pression à la manière d'une mâchoire lorsque l'on vissent les mollettes de serrage provoquant ainsi l'immobilisation du dispositif à l'échelle.The dimensions of the device are such that they adapt to all "standard" scales meeting French standards. At the end of the body of the apparatus is a concave strip which conforms to the shape of the cypress when laying a ladder provided with this device. Indeed, the foliage is only slightly crushed and deformed, while the contact surface is increased. In this context, we have excellent scale stability, the accompanying drawings illustrate the invention. - Figure 1 shows in section the device of the invention. - Figure 2 shows a top view of the device. -2 With reference to these drawings, the device comprises an aluminum part (body) consisting of a concave strip (1) and an inverted channel (2), and two stainless steel hooks (3) provided to them. end of a thread each receiving a clamping wheel (4). The long portion of a hook is housed in two orifices (5) located in the gutter of the body of the apparatus which has a total of four holes. When the hooks are positioned the clamping knobs 10 are screwed on their threads. The gutter-hooks assembly traps two bars of a ladder (6), exerting pressure in the manner of a jaw when screwing the clamping thumbs thus causing the immobilization of the device to scale.
15 Ce moyen de fixation sur une échelle permet à une personne d'utiliser ce dispositif en un temps très court et sans avoir recourt à des outils spécifiques tels que des clés, tournevis, etc_ Le bandeau concave vient ensuite épouser la surface arrondie 20 du cyprès (7) lorsque le dispositif est en utilisation. L'angulation des deux axes formée par le bandeau concave (1) et la partie longue des crochets (3) est de 110 étant donné que =L'angle entre le sol et l'échelle est de 70 (norme de sécurité).This means of attachment to a ladder enables a person to use this device in a very short time and without having recourse to specific tools such as keys, screwdrivers, etc. The concave strip then marries the rounded surface of the cypress. (7) when the device is in use. The angulation of the two axes formed by the concave strip (1) and the long part of the hooks (3) is 110 since = The angle between the ground and the scale is 70 (safety standard).
25 A titre d'exemple non limitatif le dispositif aura des dimensions de l'ordre de 45 cm de large, 30 cm de longueur et 40 cm de hauteur. Ce dispositif est particulièrement destiné à augmenter la stabilité d'une échelle contre un cyprès (cupressus 30 sempervirens) en augmentant la surface de contact entre eux.By way of nonlimiting example, the device will have dimensions of the order of 45 cm wide, 30 cm long and 40 cm high. This device is particularly intended to increase the stability of a ladder against a cypress (cupressus sempervirens) by increasing the contact surface between them.
