Abstract

Se describe una escalera que tiene una disposición de pivote bloqueable. La disposición de pivote bloqueable está ubicada y conectada entre dos secciones de escalera alargadas. Dentro de cada par de alojamientos extremos hay al menos dos receptáculos. Un mecanismo de pivote se conecta entre los alojamientos extremos y los alojamientos extremos giran al unísono y también permiten que el par de alojamientos extremos giren con respecto al alojamiento. Un mecanismo de bloqueo dentro del alojamiento tiene al menos dos miembros de bloqueo, cada uno con un accionador y cada accionador tiene un extremo libre. Hay un elemento de polarización elastomérico que actúa para polarizar los dos miembros de bloqueo y los extremos libres respectivos y los accionadores, y los dos accionadores, cuando se separan, se colocan para permitir el accionamiento con una sola mano contra la polarización para desbloquear la rotación del alojamiento.
