  • Patent number: 5335400
    Abstract: A drawstring puller and fastener that laces separable members of a shoe or the like. The free ends of a shoelace pass through openings formed in a hollow, bell-shaped socket and are formed with a knot disposed in an axial opening of the tapered plug. The axial opening is formed with an oval cross-sectional area. The plug draws the shoelace for the tightening of the shoelace lacing the separable members. While the plug draws the shoelace for the tightening of the shoelace, the knot engages the inner wall of the plug surrounding the axial opening at the oval cross-sectional area. While the shoelace is tightened by the pulling of the plug, the socket is in abutment with the separable members. While the loop of the shoelace extending from the socket is held taut, the plug, which is formed with ridges on the outer wall, is inserted and press fitted into the socket wedging securely the shoelace therebetween. The inner wall of the socket is free of ridges to enable the ridged plug to enter the socket freely.
