Abstract:
A new and improved automatic crossbar for use on passenger chairs of aerial chair-lifts for facilitating dismounting of passengers onto a landing platform comprising of:(a) at least one elongated bar, (b) said elongated bar being substantially vertical in its first closed position, (c) said elongated bar having a top and a bottom, (d) a crossbar, (e) wherein said crossbar is attached proximal to the bottom of said elongated bar, (f) a first means for pivotably mounting said elongated bar to a passenger chair, at a position substantially above said crossbar, (g) whereby said crossbar is suspended across the front of the passenger chair with said crossbar and said elongated bar in their first closed position, (h) whereby said first means for pivotably mounting said elongated bar permits said crossbar and said elongated bar to swing forward away from the front of said passenger chair to a second opened position, (i) said elongated bar having an upper portion extending above said first means for pivotably mounting, (j) a blocking structure disposed in the path of the upper portion of said elongated bar as said passenger chair moves forward to the landing platform, (k) whereby said blocking structure causes said upper portion of said elongated bar to rotate back upon impact, thereby levering forward said crossbar below pivotal mount to a second opened position, whereby said crossbar is configured to swing in a manner to pull passengers forward to a standing position, with the passenger grasping the cross bar.
