Abstract:
1. A sectional overhead garage door, comprising: a first door section having a front rear side; a second door section having a front and rear side; the first door section and the second door section being configured to be hingedly attached to each other at a location proximate to the corresponding rear side of each said first door section and said second door section for rotation in a direction there about; an upper rail being attached to the first door section, the upper rail having a front surface, an opposing rear surface and a distal edge connecting front surface and rear surface, the rear surface having a convex protrusion extending in a direction away from the rear surface; and a lower rail being attached to the second door section, the lower rail having a front surface and an opposing rear surface, the front surface having a concave portion and a concave portion which mates with the convex protrusion which extends rearward into the concave portion of the lower rail and away from the front surface of the upper rail when the first section and the second section are rotated in said direction to a closed position; wherein the concave portion of the lower rail has a radius of curvature smaller than a radius of curvature of the convex portion of the lower rail, and a rail front vertical leg of each said upper and lower rail travels during rotational motion of the upper and lower rails without engaging in said direction of rotation until the protrusion mates with he concave portion such that the edge is exposed when the first and second door sections are open or closed; wherein the top rail includes a first rotation limiter adjacent to a rear side of the first door section remote from the front side thereof, and the bottom rail includes a second rotation limiter adjacent to the rear side of the second door section and remote from the front side thereof; the first rotation limiter having a triangular cross-sectional shaped protrusion, the second rotation limiter having a cavity; the first rotation limiter configured to be received in the second rotation limiter via the triangular cross-sectional shaped protrusion and the cavity.
