Abstract

A foldable panel gate includes an inner panel section and an outer panel section foldable relative to one another between open and closed positions of the gate. An operating linkage controls displacement of the outer panel section relative to the inner panel section as the inner panel section is driven by a suitable drive between the open and closed positions. The linkage includes a pivotal body coupled to the inner panel section, a first connecting link pivotally coupled between the gate post and the pivotal body, and a second connecting link pivotally coupled between the pivotal body and the outer panel section to fold the outer panel section relative to the inner panel section through a range of 180 degrees as the inner panel section is driven through a range of 90 degrees between the open and closed position.

IPC Classes  ?

• E05F 11/28 - Mechanisms by which the bar shifts the wing shifting the wing by pivotally-connected members moving in a plane parallel to the pivot axis of the wing consisting of a lever, e.g. an angle lever, and one or more additional links
• E05F 15/10 - with rotary electromotors
• E05F 15/605 - Power-operated mechanisms for wings using electrical actuators using rotary electromotors for folding wings
