Patent

CA 2205367

A ladder is taught which is foldable into an accordion position for storage. The ladder has a pair of side rails which are formed as hinged segments (12a, 12b) to permit folding. A series of rungs extend between and are attached by hinges to the side rails. The side rails are free to rotate about the rungs between a foldable position and a position for use. The ladder is adapted to prevent inadvertent folding of the ladder during use, by limiting the rotation of the side rails with respect to the rungs.

Echelle pouvant se plier en accordéon. L'échelle comporte une paire de rails latéraux présentant la forme de segments articulés (12a, 12b), ce qui permet le pliage. Une série d'échelons s'étend entre les rails latéraux, auxquels ils sont fixés par des charnières. Les rails latéraux peuvent tourner librement autour des échelons pour alterner une position pliée et une position d'utilisation. La conception est adaptée pour éviter que l'échelle se plie accidentellement pendant l'utilisation, dans la mesure où la rotation des rails latéraux relativement aux échelons est limitée.
