Quick connect and disconnect rope system

Abstract

Implementations of a quick connect and disconnect (QCD) system for connecting and disconnecting a load via a rope to a pulling force include a primary load bar connected to a first rail and a second rail and a compression pin assembly to be inserted between the first rail and the second rail. The rails may be in a variety of configurations to accommodate different hitching systems for a pulling force. The rope, the primary load bar, and the compression pin are used to form a knot that may be tied and untied relatively quickly. One end of a QCD system can be attached to a pulling force and one leg of the knot formed on the QCD may be connected to a load. In this way, a load can be connected to and disconnected from a pulling force relatively quickly.

1 . A quick connect and disconnect (QCD) system for connecting/disconnecting a load via a rope to/from a pulling force comprising:
 a first rail having a first hole;   a second rail having a second hole;   a primary load bar connected between the first and second rails; and   a compression pin assembly wherein the compression pin assembly includes a handle; a shaft; a dowel pin inserted through the shaft at a first location wherein the ends of the first pin extend from the shaft; and a compression spring located around the shaft between the first pin and the handle,   wherein the first hole of the first rail and the second hole of the second rail are configured to receive the shaft of the compression pin and wherein the compression spring is of a sufficient diameter so that the first rail blocks the compression spring from being inserted into the first hole.   
     
     
         2 . The QCD system of  claim 1  wherein the primary load bar comprises an outer tube and an inner tube wherein the inner tube attaches to the first and second rails and the outer tube is configured to spin around the inner tube. 
     
     
         3 . The QCD system of  claim 1  wherein the second hole of the second rail includes a slot to receive the shaft and the dowel pin of the compression pin when the pin is in a first direction lengthwise. 
     
     
         4 . A method of tying a knot using the QCD system of  claim 1  comprising:
 folding a rope at any point along the rope to create a loop, a first rope leg, and a second rope leg; 
 then bringing the loop under, up, and over the primary load bar; 
 then bringing the loop between the first rope leg and the second rope leg; 
 then bringing the loop under, up, and over the primary load bar again; 
 then bringing the loop over the first rope leg and the second rope leg; 
 then pulling a portion of the first rope leg and the second rope leg between the loop such that the ends of the first rope leg and the second rope leg hang under the loop; 
 inserting the compression pin shaft through a tunnel produced by pulling a portion of the first rope leg and the second rope leg between the loop; 
 inserting the compression pin through the second hole of the second rail while the pin is in the first direction lengthwise; and 
 rotating the compression pin to position the dowel pin in a second direction lengthwise to lock the compression pin to the second rail. 
 
     
     
         5 . A method of untying the knot of  claim 4  comprising:
 removing the compression pin from the second rail by rotating the compression pin to position the dowel pin back in the first direction lengthwise so that the dowel pin may be passed back through the second hole. 
 removing the compression pin from the tunnel; and 
 pulling the first rope leg and the second rope leg to unwrap the loop from the primary load bar. 
 
     
     
         6 . A method of tying a knot using a quick connect and disconnect (QCD) system wherein the QCD system comprises a first rail; a second rail; and a primary load bar connected between the first and second rails, the method comprising:
 folding a rope at any point along the rope to create a loop, a first rope leg, and a second rope leg;   then bringing the loop under, up, and over the primary load bar;   then bringing the loop between the first rope leg and the second rope leg;   then bringing the loop under, up, and over the primary load bar again;   then bringing the loop over the first rope leg and the second rope leg;   then pulling a portion of the first rope leg and the second rope leg between the loop such that the ends of the first rope leg and the second rope leg hang under the loop; and   inserting a shaft through a tunnel produced by pulling a portion of the first rope leg and the second rope leg between the loop.   
     
     
         7 . A method of untying the knot of  claim 6  comprising:
 removing the shaft from the tunnel; and 
 pulling the first rope leg and the second rope leg to unwrap the loop from the primary load bar.
