  • Hinged connection for a tilt up device
    Patent number: 5528796
    Abstract: A hinge assembly removably connects two bodies for pivotable movement relative to one another. The hinge assembly includes a first convex arcuate surface and a first concave arcuate surface on one body and a second convex arcuate surface and a second concave arcuate surface on the other body. The radii of curvature of the first convex arcuate surface and the second concave arcuate surface are about equal, and the radii of curvature of the second convex arcuate surface and the first concave arcuate surface are about equal, and each surface preferably defines an arc of about 180 degrees. The bodies may be assembled to one another so that the first convex arcuate surface slidingly engages the second concave arcuate surface and the first concave arcuate surface slidingly engages the second convex arcuate surface, thereby preventing relative movement of the bodies in a direction transverse to the pivot axis.
