ABSTRACT:
The variable-speed conveyor element applied to a handrail is made up of individual handles linked together by elements of variable length which themselves function like elements of the handrail. Each of these variable-length elements is formed from a continuous flexible link, such as a belt or cable, to which are fitted contiguous blocks which stop or limit the bending of the elements in one direction. The blocks have projections and recesses allowing them to mutually interlock and ensure the transmission of forces.
