Abstract
L'invention concerne les échelles à coulisse en alliage léger qui comprennent au moins deux plans constitués chacun par deux montants profilés et maintenus rigidement assemblés par des échelons. Chaque montant 3 présente en section droite une nervure 6 et une rainure 7 de formes exactement complémentaires, tandis que les échelons 13 présentent une section droite carrée ou rectangulaire entre leurs bourrelets 8 et une petite section circulaire au niveau de leurs extrémités serties 12. L'invention est applicable aux échelles à coulisse nécessitant un guidage précis et continu de leurs plans.
