Abstract
An outer door designed to open outward where the space to open outward is severely restricted. The top of the outer door rotates upward about a horizontal axis as the bottom of the outer door rotates about a vertical axis. A cross bar fixedly attached to the bottom of the outer door pulls the top of the outer door via at least one spring so that the outward motion of the bottom of the outer door lifts the top of the outer door, and then allows the top of the outer door to become vertical again when the bottom of the outer door is returned to the entryway in a closed position.
