发明名称 Automatically resettable guide system for an overhead door
摘要 The present invention is a device which is designed to allow a door to give way when impacted by an outside force such as a forklift, reducing damage. The present invention requires less force to be activated, which allows its use on wider doors than were previously possible. The present invention is also able to reset itself, depending upon how much distance was traveled during the impact. The present invention requires less maintenance than other devices currently in use.
