Patent attributes
There is provided a tie knot member for an elongated strip of fabric. The tie knot member includes a shell having a truncated, conical shape with a cardioid-like cross-section. The shell has a base end with a lower aperture. The shell has a top end with an upper aperture. The shell has a rear portion extending between the base end and the top end. The rear portion includes a cusp and a pivotable connector connecting the shell across the cusp. The pivotal connector is so positioned to retain the shape 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.
