Abstract

The invention relates to a mechanical apparatus on which its user stands and causes himself to be carried about in the vertical and horizontal planes in order to perform overhead work. With reference to the drawing: (1) is a self-propelling carriage with two vertical runners (2) enclosing the platform (3) elevating device. The platform on which the user stands is equipped with a safety cage (4) the top of which carries the console (5) for the forward, reverse and steering controls (18) of the carriage and the controls for raising and lowering the platform (3). Applications: secondary work on the building, maintenance, and in a more general way any continuous overhead work. <IMAGE>

Description

La présente invention a pour objet un engin mécanique qui permet à l'utilisateur autoporté de se déplacer dans les plans horizontaux et verticaux pour l'exécution de travaux en hauteur.The present invention relates to a mechanical device which allows the self-supporting user to move in the horizontal and vertical planes for the execution of work at height.

En l'état actuel de la technique les travaux en hauteur notamment dans le second oeuvre du bâtiment sont réalisés à l'aide d'échelles doubles ou d'escabeaux, l'invention citée vise à pallier trois défauts majeurs de ces appareils.

  • 1/ L'utilisateur d'une échelle double ou d'un escabeau est contraint après exécution partielle de sa tâche de des­cendre au sol, de repositionner son escabeau ou échelle et de regravir les marches. Cette opération qui se renouvelle fré­quemment constitue une perte de temps et d'énergie inutile.
  • 2/ Le positionnement en hauteur de l'utilisateur est approximatif à savoir ± 20 cms ( hauteur d'une marche ) d'où mauvaises conditions de travail entrainant fatigue.
  • 3/ De la faible largeur des marches ou barreaux découle une position de l'utilisateur " perchée " qui l'oblige par­fois à mobiliser une main pour se maintenir en sécurité, d'où diminution de ses capacités fonctionnelles pour le travail à accomplir.
In the current state of the art, work at height, particularly in the finishing work of the building, is carried out using double ladders or stepladders, the cited invention aims to remedy three major faults of these devices.
  • 1 / The user of a double ladder or a stepladder is forced after partial execution of his task to descend to the ground, to reposition his stepladder or ladder and to climb up the steps. This operation, which is repeated frequently, is an unnecessary waste of time and energy.
  • 2 / The user's height positioning is approximate, namely ± 20 cms (height of one step), hence poor working conditions resulting in fatigue.
  • 3 / The narrow width of the steps or bars gives rise to a "perched" position of the user which sometimes forces him to mobilize a hand to keep himself safe, hence his functional capacity for the work to be accomplished.

Le chariot ascenseur remplace escabeaux et échelles dou­bles et apporte une nette amélioration de la productivité puis­qu'il supprime les temps morts, améliore le confort, la sécu­rité et diminue la fatigue de l'utilisateur.The lift trolley replaces stepladders and double ladders and provides a significant improvement in productivity since it eliminates downtime, improves comfort, safety and reduces user fatigue.

A titre d'exemple un peintre pourra réaliser la finition d'un plafond en continu puisqu'il se déplacera à volonté à la bonne hauteur de travail.For example, a painter can finish the ceiling continuously since he can move at will at the right working height.

Une forme d'exécution de l'invention est décrite ci-après à titre indicatif et nullement limitatif. En se référant au dessin annexé le chariot ascenseur se compose essentiellement de deux parties :

  • 1/ Un chariot auto-moteur 1 avec deux coulisses verti­cales 2.
  • 2/ Une plateforme élévatrice 3 sur laquelle prend place l'utilisateur debout, munie d'une nacelle de sécurité 4 qui supporte en partie supérieure le tableau des commandes 5. Cette plateforme monte ou descend entre les deux coulisses.
An embodiment of the invention is described below by way of indication and in no way limitative. Referring to the attached drawing, the lift trolley essentially consists of two parts:
  • 1 / A self-propelled carriage 1 with two vertical slides 2.
  • 2 / A lifting platform 3 on which the standing user takes place, provided with a safety nacelle 4 which supports in the upper part the control panel 5. This platform goes up or down between the two slides.

Le chariot mobile est un chassis équipé de quatre roues dont deux sont motrices 6, entrainées par un arbre 7 ( suivi d'un différentiel 8 ) sur lequel est calé un engrenage 9 ac­couplé au moteur-réducteur-frein 10 alimenté en courant par les batteries rechargeables 11 par l'intermédiaire d'un con­tacteur de commande situé sur le tableau 5. Les deux roues avant ( non représentées sur le dessin ) sont directionnelles, couplées à la colonne de direction télescopique 12, avec vo­lant 18 monté sur le tableau 5.The mobile carriage is a chassis fitted with four wheels, two of which are driven 6, driven by a shaft 7 (followed by a differential 8) on which is fixed a gear 9 coupled to the motor-reducer-brake 10 supplied with current by the batteries rechargeable 11 via a control switch located on the panel 5. The two front wheels (not shown in the drawing) are directional, coupled to the telescopic steering column 12, with steering wheel 18 mounted on the panel 5.

A l'intérieur des deux oulisses 2 se meut de façon cir­culaire une chaine à maillons type " Brampton " 13 qui est ac­tionnée par un pignon moteur 14 calé sur l'arbre 15 qui est accouplé au moteur-réducteur-frein 16 télécommandé depuis le tableau 5. En partie supérieure la chaine roule sur le pignon 17 monté fou sur arbre. Ces deux chaines sans fin droite et gauche sont couplées à la plateforme élévatrice 3 et leur mise en mouvement simultané permet la montée ou la descente de celle-ciInside the two runners 2 moves in a circular fashion a "Brampton" type chain link 13 which is actuated by a motor pinion 14 fixed on the shaft 15 which is coupled to the motor-reducer-brake 16 remote controlled from the switchboard 5. In the upper part the chain rolls on the pinion 17 mounted idle on the shaft. These two endless chains, right and left, are coupled to the lifting platform 3 and their simultaneous movement allows the ascent or descent of the latter.

Le talbeau des commandes 5 situé à hauteur de ceinture de l'utilisateur regroupe donc les fonctions marche avant, arriè­re et direction du chariot, ainsi que le montée ou descente de la plateforme. Il est fixé à la nacelle 4 qui constitue une sécurité anti-chûte.The control panel 5 located at the user's waist height therefore combines the forward, reverse and direction of the truck functions, as well as the raising or lowering of the platform. It is fixed to the nacelle 4 which constitutes an anti-fall safety device.

Cette dernière pourra être équipé d'une rehausse réglable en hauteur ( au dessus de la tête de l'utilisateur ) munie de rouleaux libres montés sur amortisseurs, destinée à l'élévation des plaques de plâtre ou autres matériaux en plafond et à leur maintient pendant vissage.The latter can be fitted with a height-adjustable riser (above the user's head) fitted with free rollers mounted on shock absorbers, intended for raising plasterboard or other ceiling materials and for maintaining them for screwing.

Elle pourra également être munie de prises de courant pour alimentation d'outillage portatif, de supports ou bacs pour matériaux utilisés.It may also be fitted with sockets for supplying portable tools, supports or trays for the materials used.

Il est bien évident que la présente invention n'est pas limitée au mode de réalisation décrit et représenté qui cons­titue seulement un exemple. On peut envisager une source d'­énergie autre que les batteries, et les chaines cinématiques des différents mouvements peuvent être conçues différemment.It is obvious that the present invention is not limited to the embodiment described and shown which is only an example. We can consider a source of energy other than batteries, and the kinematic chains of the different movements can be designed differently.

Ce chariot ascenseur peut trouver de nombreuses utili­sations dans les travaux de peinture, électricité, pose de plafonts, entretien divers, et d'une manière plus générale dans tous les travaux en hauteur au suivi.This lift cart can find many uses in painting, electricity, ceiling installation, various maintenance, and more generally in all work at height monitoring.
