摘要:
An upward acting sectional door is disclosed having pinch-resistant joints and hinges. The hinges have a top member securable to the upper panel and a base member securable to the lower panel. The base member and top member are connected by first and second links, each of which have a first end pivotally connected to the top member and a second end pivotally connected to the base member. The geometry of the links insures that a foot which depends from the upper panel is always spaced closely enough to the lower panel that a person cannot easily insert a fingertip into the joint. The foot also acts to push a fingertip away from the joint as the door is closed. A door seal on each panel moves to engage the adjacent panel when the door is closed, but lifts away as the door opens.
