Abstract

Abstract A quick-release mechanical knot device for use in securing objects together having a novel means for quickly and safely releasing the mechanical knot device from the body of a rope or tether regardless of the amount of tension or load strain acting on the rope. The device comprises a semi-rigid elongated stock member having at least two circular orifices formed at opposing ends of a curvilinear intermediate portion. The first and second orifices are substantially perpendicular to the linear length of the stock member and formed with a substantially parallel and concentric axis to one another. A leading end of a rope is inserted through the first and second circular orifices of the stock member and wrapped around a stationary or movable object to form a hitch. The leading end of the rope is then placed between the curvilinear intermediate portion of the stock member and the portion of the rope passing between the first and second orifices to form a capture for the portion of the rope therebetween. After forming a loop, the leading end of the rope is passed back through the intermediate portion of the stock member and the capture and maintained therebetween. To release the holding integrity of the stock member, the leading end of the rope is pulled tightly to remove the portion of the rope secured between the intermediate portion of the stock member and the rope capture thus freeing the retention of the bight formed in the rope.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 176 words
A combination for securing a tethering material to a support member or other structure, comprising: a mechanical knot device, comprised of: a stock member having a first end and a second opposing end; a first orifice disposed at said first end of said stock member and having an opening formed therein; a second orifice disposed at said second end of said stock member and having an opening formed therein, said opening of said second orifice being substantially aligned axially with said opening of said first orifice; and an intermediate portion extending between said first end and said second end, said intermediate portion having a uniform curvilinear configuration; and a tethering material including a leading end, a second opposing end and two loop portions, said leading end being introduced through said first and second orifices of said stock member, said first loop portion passing outwardly from said orifices and extending substantially around said support member, said second loop portion being received between said intermediate portion of the stock member and said leading end of said tethering material.
Claim 2
Dependent Claim 176 words
A combination for securing a tethering material to a support member or other structure, comprising: a mechanical knot device, comprised of: a stock member having a first end and a second opposing end; a first orifice disposed at said first end of said stock member and having an opening formed therein; a second orifice disposed at said second end of said stock member and having an opening formed therein, said opening of said second orifice being substantially aligned axially with said opening of said first orifice; and an intermediate portion extending between said first end and said second end, said intermediate portion having a uniform curvilinear configuration; and a tethering material including a leading end, a second opposing end and two loop portions, said leading end being introduced through said first and second orifices of said stock member, said first loop portion passing outwardly from said orifices and extending substantially around said support member, said second loop portion being received between said intermediate portion of the stock member and said leading end of said tethering material.
