Patent ID: 7930806

Claim:
A tie knot member for an elongated strip of fabric, the tie knot member comprising: a shell having a truncated, conical shape with a cardioid-like cross-section, the shell having a base end with a lower aperture, a top end with an upper aperture, and a rear portion extending between the base end and the top end, the rear portion including a cusp; and a pivotable connector connecting the shell across the cusp, the pivotable connector being so positioned to retain the shape of the shell and allow pivoting action around the pivotable connector that results in a restricting reaction at the lower aperture of the shell, whereby when the elongated strip of fabric is passed through the shell and the shell is spread at the top end, the upper aperture is enlarged and the lower aperture is reduced, thereby cinching the lower aperture against the elongated strip of fabric.
