Abstract
La presente invención se refiere a una escalera caracterizada porque comprende: un primer ensamble que tiene un par de barandas interiores y un par de barandas exteriores, el par de barandas interiores se acoplan con el par de barandas exteriores de manera deslizable; y por lo menos un mecanismo de bloqueo configurado para pivotear entre una primera posición y segunda posición, el mecanismo de bloqueo comprende: una abrazadera acoplada a una primera baranda exterior del par de barandas exteriores, una palanca pivotante acoplada a la abrazadera por medio de un pasador de pivote, la palanca siendo sesgada hacia la primera posición, la palanca incluye una primera porción que se extiende desde el pasador de pivote en una primera dirección, y la palanca incluye una segunda porción que se extiende desde el pasador de pivote en una segunda dirección opuesta a la primera dirección que se extiende lejos de la primera porción, un pasador de acoplamiento acoplado directamente de forma pivotante a la segunda porción de la palanca por medio de un pasador de acoplamiento, en donde el al menos un mecanismo de bloqueo está configurado de modo que la aplicación de una fuerza a la primera porción de la palanca en una dirección hacia dentro hacia la primera baranda exterior hace que la palanca gire alrededor del pasador de pivote desde la primera posición a la segunda posición provocando que el pasador de acoplamiento sea desplazado en una dirección hacia fuera lejos de la primera baranda exterior, la palanca está configurada para ser posicionada de forma selectiva entre la primera posición y la segunda posición, siendo la primera posición cuando el pasador de acoplamiento pasa a través de una abertura en una primera baranda interior del par de barandas interiores que impide el movimiento relativo entre los barandas interior y exterior, siendo la segunda posición cuando el pasador de acoplamiento está retraído desde la apertura de la primera baranda interior para permitir el movimiento relativo entre barandas interiores y exteriores, y un mecanismo de retención configurado para mantener la palanca en la segunda posición tanto como el pasador de acoplamiento está alineado con la abertura en la primera baranda interior, el mecanismo de retención se configura para liberar la palanca desde la segunda posición como un resultado directo de la aplicación de una fuerza predeterminada en la dirección hacia el interior hasta la segunda porción de la palanca.
