Abstract

The ladder has parallel front legs (1) composed of upper tubes (2) and lower tubes (3). The lower tubes are vertically slid in upper tubes. The upper tubes are connected by a crosspiece (4), and the lower tubes are connected by another crosspiece (5). Parallel rear legs (6) are connected by steps. A plate (9) is connected to the rear legs and to the upper tubes of the front legs through a pivot connection (7). Stops (8) i.e. small tubes, are placed on each side of the front legs.

Description

-1- -1-

La présente invention concerne le confort et la sécurité de tout ouvrier , tout bricoleur ou toute personne utile- sant un escabeau . Il s'agit d'un escabeau dont les deux pieds de devant coulissent par le biais de tubes . Ce sys- tème permet d'utiliser l'escabeau en toute sécurité dans tous les escaliers . Des butées d'arrêts placés sur les cotés des tubes supérieurs avants permettent de stabiliser l'es- cabeau en les insérant dans les trous des tubes supérieurs traversant également les tubes inférieurs par leurs trous . En effet , dans quelque position que ce soit , ses marches et son plateau restent parfaitement à l'horizontal en étant dans des marches d'escalier . Or ceci est absolument im- possible avec les escabeaux actuels . Une liaison pivot permet de plier l'escabeau lorsqu'il n'est pas utilisé . L'escabeau peut compter de trois à six marches car ce système est compatible avec le nombre des marches . L'escabeau a deux pieds avants parallèles entre eux et reliés entre eux par des traverses , ces pieds étant composés de deux premiers tubes supérieurs et de deux seconds tubes inférieurs.Les deux seconds tubes inférieur coulissent dans les deux premiers tubes de façon télescopique . Les deux premiers tubes étant reliés entre eux par au moins une traverse et les deux seconds tubes également par au moins une traverse . Les deux pieds arrières sont parallèles entre eux et reliés par des mar- ches . Ces derniers étant composés de deux tubes non coulissant .Le plateau est relié d'une part aux pieds arriè- res et d'autre part aux deux tubes supérieurs des pieds -2-avants . La liaison entre le plateau et les deux pieds arrières et la liaison entre le plateau et les deux premiers tubes avants est une liaison pivot , permettant ainsi le pliage de l'escabeau . Les butées d'arrêts sont deux petits tubes placés de chaque coté des deux pieds avants sur les deux premiers tubes supérieurs , permettant ainsi de bloquer les deux seconds tubes inférieurs dans la position souhaitée The present invention relates to the comfort and safety of any worker, handyman or anyone using a stepladder. It is a stepladder whose two front feet slide through tubes. This system makes it possible to use the ladder safely on all stairs. Stopping stops placed on the sides of the upper front tubes make it possible to stabilize the stool by inserting them into the holes of the upper tubes which also pass through the lower tubes through their holes. Indeed, in any position whatsoever, its steps and its plateau remain perfectly horizontal while being in steps of stairs. This is absolutely impossible with today's stools. A pivot connection makes it possible to fold the stepladder when not in use. The stepladder can count from three to six steps because this system is compatible with the number of steps. The stepladder has two front feet parallel to each other and interconnected by sleepers, these feet being composed of two upper tubes and two second lower tubes. The second two lower tubes slide in the first two tubes telescopically. The first two tubes being interconnected by at least one cross and the two second tubes also by at least one cross. The two rear feet are parallel to each other and connected by steps. The latter being composed of two non-sliding tubes. The plate is connected on the one hand to the back feet and on the other hand to the two upper tubes of the front feet. The connection between the plate and the two rear legs and the connection between the plate and the first two front tubes is a pivot connection, thus allowing the folding of the stool. The stop stops are two small tubes placed on each side of the two front legs on the first two upper tubes, thus making it possible to block the two second lower tubes in the desired position.
