US 9,789,410 B2 · Auto reset zip line

Abstract

An auto reset zip line assembly comprising a cable running along the circumference of two pulleys that are spaced apart forming a closed loop is provided. A pair of rigid frames are fixedly coupled to the cable at an equal distance from each other. The pulley includes a wheel having a rim that has a continuous trough along the circumference to retain the cable. The wheel is rotatably mounted on a shaft and the shaft is mounted to a hosing. The pulleys include a mechanism to suspend a zip line assembly between two vertical supports. The auto reset zip line assembly further comprises a braking mechanism and a pair of guarding plates coupled to the housing to prevent derailing and entangling of the cable. The invention is advantageous by providing a safe zip line assembly that obviated the need of returning a trolley to the starting point of the zip line.
