Description

- 1- 1

L'Homme utilise certains matériels comme les échelles, les escabeaux, les plates-formes individuelles de travail pour lui permettre de réaliser différents travaux à des hauteurs variables.  Man uses certain materials such as ladders, stepladders, individual work platforms to enable him to carry out various works at variable heights.

Pour satisfaire cette variabilité des hauteurs d'intervention les matériels utilisés sont souvent équipés de marches fixes et de pieds télescopiques réglables permettant d'atteindre des hauteurs de travail plus grandes. Pour compenser ces réglages une marche ou un échelon est rajouté par rabattement sur les pieds télescopiques. Cette disposition 10 connue ne permet pas d'obtenir toute la rigidité et par voie de conséquence la sécurité offerte par ce type de marche.  To meet this variability in intervention heights, the equipment used is often fitted with fixed steps and adjustable telescopic feet, allowing greater working heights to be achieved. To compensate for these adjustments, a step or a rung is added by folding down on the telescopic legs. This known arrangement 10 does not make it possible to obtain all the rigidity and consequently the security offered by this type of walk.

La présente invention a pour but de remédier à ces insuffisances en complétant les matériels pourvus de pieds télescopiques d'une mar15 che coulissante escamotable. Cette marche coulissante située au niveau de la partie télescopique sortante des pieds, permet d'éviter un espacement trop important entre le sol d'appui et la première marche fixe inférieure lorsque les pieds télescopiques sont déployés. Ainsi, l'utilisateur pourra monter ou descendre en toute sécurité sans subir de décalage 20 désagréable, voire dangereux entre le sol d'appui et la marche inférieure fixe du matériel.  The object of the present invention is to remedy these shortcomings by supplementing the materials provided with telescopic feet with a retractable sliding step. This sliding step located at the level of the outgoing telescopic part of the feet, makes it possible to avoid too great a spacing between the support floor and the first lower fixed step when the telescopic feet are deployed. Thus, the user can go up or down safely without undergoing an unpleasant, or even dangerous, offset between the support floor and the fixed bottom step of the equipment.

Cette marche coulissante ajoutée entre les pieds est conçue de manière à offrir, d'autre part, une grande résistance aux effets de tor25 sion dus aux effets de montée et de descente sous le poids de l'utilisateur. En position repliée, cette marche est maintenue sous la première marche inférieure fixe de l'appareil. Ce maintien est assuré par clipsage de façon à éviter toute gêne pour l'utilisateur lorsque l'utilisation de cette marche coulissante n'est plus nécessaire. 30 La marche additionnelle coulissante escamotable est constituée de deux tubes horizontaux venant de part et d'autre des génératrices des pieds télescopiques et sont réunis par deux plats. C'est cette disposition qui assure la bonne résistance à l'effet de torsion évoqué précédem35 ment.  This sliding step added between the feet is designed so as to offer, on the other hand, great resistance to the effects of torsion due to the effects of rising and falling under the weight of the user. In the folded position, this step is maintained under the first fixed bottom step of the device. This maintenance is ensured by clipping so as to avoid any discomfort for the user when the use of this sliding step is no longer necessary. 30 The additional retractable sliding step consists of two horizontal tubes coming from either side of the generators of the telescopic legs and are joined by two plates. It is this arrangement which ensures good resistance to the torsion effect mentioned previously.

Les deux plats reliant les deux tubes horizontaux supportent deux tubes verticaux coulissants. Ce coulissement se fait dans deux tubes fourreaux solidaires des pieds télescopiques. La constitution des autres 40 marches fixes de l'appareil par deux tubes parallèles permet de faire coulisser entre ceux-ci les deux tubes verticaux de la marche additionnelle coulissante escamotable. Ce coulissement de la valeur d'un espacement entre marche est limité par des butées situées sur l'extrémité supérieure des tubes fourreaux de guidage.  The two plates connecting the two horizontal tubes support two vertical sliding tubes. This sliding is done in two sheath tubes integral with the telescopic legs. The constitution of the other 40 fixed steps of the device by two parallel tubes allows the two vertical tubes of the additional retractable sliding step to slide between them. This sliding of the value of a spacing between steps is limited by stops situated on the upper end of the guide sleeve tubes.

La figure 1 représente, à titre d'exemple, une vue en perspective d'une plate-forme individuelle de travail pieds télescopiques sortis, équipée de la marche additionnelle coulissante escamotable.  FIG. 1 represents, by way of example, a perspective view of an individual working platform with telescopic legs extended, equipped with the additional retractable sliding step.

La figure 2 représente une vue partielle et en perspective des pieds télescopiques, coté marches fixes, sortis et la marche additionnelle coulissante escamotable déployée.  Figure 2 shows a partial perspective view of the telescopic legs, fixed steps side, out and the additional retractable sliding step deployed.

La figure 3 représente une vue partielle en perspective vue de des10 sous de deux marches fixes de la plate-forme individuelle de travail avec pieds télescopiques rentrés, dont la marche additionnelle coulissante escamotable est clipsée sous la marche fixe inférieure.  FIG. 3 represents a partial perspective view seen from des10 under two fixed steps of the individual work platform with retracted telescopic legs, the additional retractable sliding step of which is clipped under the lower fixed step.
