Claims: What is claimed is:

1. Closure hardware adapted to mount swingably a closure in a vertical disposition to a support frame defining a vertical opening to enable the closure to swing between an open position out of the plane of the opening and a closed position disposed within the plane of the opening, comprising:

an upper universal mounting device adapted to mount the top edge of the closure at a corner portion thereof to the frame to support swingably and universally the closure from the frame about a point disposed within the plane of the opening so that the closure disposed normally at rest in the closed position can swing out of the plane of the opening and the lower portion of the closure can tilt upwardly relative to the upper portion thereof; and

a lower universal mounting device adapted to mount the side edge of the closure near the bottom edge thereof below said upper device to the adjacent portion of the frame to cause the lower portion of the closure to swing about a point outside of the plane of the opening and to cause the lower portion of the closure to tilt upwardly as the closure swings open so that when the closure is released from its open position, it falls from its open position under the force of gravity to its closed position.

2. Closure hardware according to claim 1, wherein said upper mounting device includes a first upper bracket adapted to be attached to the support frame and having an upstanding truncated sphere extending therefrom for extending in the plane of the opening, said sphere being joined to said bracket by an intermediate truncated conical portion, said upper mounting device including a second upper bracket having a depending socket adapted to be attached to said closure for swivelly and rockably receiving said truncated sphere and said conical portion.

3. Closure hardware according to claim 2, wherein said lower mounting device includes a first lower bracket adapted to be attached to the lower portion of the support frame and having at least one socket fixed thereto and disposed out of the plane of the opening on one side of the closure, an arm, a second lower bracket adapted to be attached to the lower side edge of the closure and having a sphere mounted on the distal end portion of said arm extending from said second lower bracket and swivelly attached to said socket.

4. Closure hardware according to claim 3, further including a second socket mounted on the other side of the closure extending out of the plane of the opening, a second sphere fixed to the opposite end of said arm to swivelly attach to said second socket.

5. Closure hardware according to claim 4, wherein each one of said spheres includes diametrically opposed flats.

6. Closure hardware according to claim 5, wherein each one of said sockets includes a C-shaped band of metal.
