Abstract
A door assembly includes multiple door panels arranged in series along laterally spaced tracks, extending laterally between the tracks, and supported for movement on the tracks. A first pair of hinge plates is secured to a first door panel, each member of the first pair being located at an opposite lateral side of the first panel. A second pair of hinge plates is secured to a second door panel, each member of the second pair being located at an opposite lateral side of the second panel. A first release pin alternately disconnects and connects the first and second hinge plates at the first lateral side of the door panels. A second release pin alternately disconnects and connects the first and second hinge plates at the second lateral side of the door panels.

A garage door assembly for an opening comprising:
- first and second garage door panels;
- a first pair of hinge plates secured to the first panel, each member of the first pair being located at one of respective first and second lateral sides of the first panel;
- a second pair of hinge plates secured to the second panel, each member of the second pair being located at one of respective first and second lateral sides of the second panel;
- a first release pin secured to and pivotably supported on one hinge plate of the first and second hinge plates at the first lateral side of the panels, and elastically biased toward engagement with the first and second hinge plates located at the first lateral side of the panels;
- a second release pin secured to and pivotably supported on one hinge plate of the first and second hinge plates at the second lateral side of the panels, and elastically biased toward engagement with the first and second hinge plates located at the second lateral side of the panels;
- first and second laterally spaced tracks;
- a first roller supported on the first track and secured to one of the hinge plates of the first pair of hinge plates;
- a second roller supported on the second track and secured to the other hinge plate of the first pair of hinge plates;
- a third roller supported on the first track and secured to one of the hinge plates of the second pair of hinge plates;
- and
- a fourth roller supported on the second track and secured to the other hinge plate of the second pair of hinge plates;
- and
- wherein each member of the first hinge plate pair includes:
- a first attachment plate secured to the first panel;
- first and second legs, each leg extending from the first attachment plate and having first attachment hole aligned with the first attachment hole of the other leg;
- wherein each member of the second hinge plate pair includes:
- a second attachment plate secured to the second panel;
- third and fourth legs, each leg extending from the second attachment plate and having a second attachment hole aligned with the second attachment hole of the other leg;
- and
- wherein each release pin includes a first axis and a second axis, a latch pin and spring aligned along the first axis, and first and second latch pins aligned along the second axis, said second axis spaced and parallel to the first axis, said spring for biasing said first and second latch pins toward engagement with the first and second hinge plates located on the same lateral side of the panels, so that the first release pin alternately disconnects and connects the first and second hinge plates at the first lateral side of the panels upon disengaging and engaging, respectively, the corresponding first and second attachment holes, and the second release pin alternately disconnects and connects the first and second hinge plates at the second lateral side of the panels upon disengaging and engaging, respectively, the corresponding first and second attachment holes.
