HEAD CURTAINS FOR DOCK SHELTERS OR DOCK SEALS

摘要

A dock apparatus comprising first and second weather barriers positioned
laterally of a doorway of
a loading dock and compressible by a vehicle, the lateral weather barriers
include inner surfaces to bulge
toward each other in response to the vehicle compressing the lateral weather
barriers, and a head curtain at
least partially positioned between the lateral weather barriers and being
engagable by the vehicle, the head
curtain having a lateral stiffness such that in response to the vehicle
engaging the head curtain and
compressing the lateral weather barriers, the head curtain becomes pinched
between the bulging inner
surfaces to restrict a vertical movement of the curtain.
