Patent ID: 8539651

Claim:
A replacement slider to repair a broken zipper, comprising: a bottom plate having a Y-shaped channel formed in an upper surface thereof; a top plate having a similar Y-shaped channel formed in a lower surface thereof; a spring to urge the top plate apart from the bottom plate; a pillar having a V shape directed toward a joint between right and left arms of the Y-shaped channel channels, reversibly joining the bottom plate to the top plate, said pillar comprising: a keyed protrusion extending upward from the upper surface of the bottom plate, the keyed protrusion having a cup in its upper extremity to accept a lower end of the spring; a V-shaped pillar having a corresponding keyed indentation, said pillar extending downward from the lower surface of the top plate; said keyed protrusion adapted to fit slidably inside said keyed indentation so that sliding motion of the protrusion within the indentation alters a compression of the spring and alters a distance between the top plate and the bottom plate; and a threaded fastener to adjust a maximum distance by which the spring can separate the top plate and the bottom plate.
