Overhead door with spring-loaded roller hinges
An overhead door with spring-loaded roller hinges that push the door against its frame or weather stripping to provide an effective weather and thermal seal when the door is closed. The spring-loaded roller hinges are readily retrofit to overhead doors with conventional roller hinges. Each hinge spaces and pivotally secures a roller hub from the base of the hinge. The roller hub is pivotally secured to an inside flange and movably held by an elongated slot in an outer flange. The roller hub supportingly receives the axel of a wheel that rollingly engages a track fixed to the vertical sides of the door frame. Each roller hinge has a spring that biases its roller hub and wheel rearwardly against the fixed track, which pushes the door panels forward and into sealing engagement with the door frame or its weather stripping.
