The LeverKnot® improves upon the basic principle used in tent tie-downs. Conventional tent tie-downs consist of a rope with a loop tied in one end and placed over the top of the tent’s support pole. The other end of the rope passes through one end of a line tightener (usually a small flat piece of plastic) and is permanently attached to the other end of the line tightener creating a loop. The loop created by the rope and the line tightener fastens around a tent stake in the ground. As the line tightener is moved away from the tent stake, the rope tightens to hold the support pole erect. When the line tightener is released, the tension of the rope rotates it towards the tent stake. This action binds the rope in the hole at the other end of the line tightener as illustrated in the inset in below.

 

The LeverKnot makes two significant improvements to this design.

1. The Rope Is Removable.

This allows the rope used with the LeverKnot to be wrapped around a tree or through the handle of a lawnmower. The attachment method requires no tools or special hardware and can be used with any piece of rope.

2. Locking Mechanism.

The LeverKnot has a unique locking mechanism that holds rope securely in place around any size object as opposed to conventional tent tie-downs.

For ex: If a tent owner wanted to tie the tent support pole to a tree rather than a stake in the ground, the rope would first need to be untied from the plastic piece, placed around the tree, then re-tied to the plastic piece. After completing this time consuming process, the tent owner might find that the diameter of the tree prevents the plastic piece from securely locking in place, thus allowing it to move freely along the rope. See below.

 

LeverKnot solves this problem by featuring a D-ring lock contained in a slot that runs through the center of the LeverKnot base. When the D-ring is in the lower (Unlocked) position, the rope is free to move and may be adjusted just as in the existing tie-down method. However, when the D-ring is moved to the upper (Locked) position it secures the rope to the LeverKnot and prevents slipping. The figure below shows the D-ring in the locked position.

 

The LeverKnot will work in most any linear (adjusting the length of a rope) situation. In addition, the locking mechanism also allows the LeverKnot to create a secure loop that can be used to tie objects together.

In the above illustration the D-ring is in the “Locked” position. The tension on the rope pulls on the D-ring forcing it towards the LeverKnot. This force “pinches” the rope keeping it secure. The more tension that is placed on the rope, the more force is applied to the D-ring which insures that the rope remains secure. This unique feature of the LeverKnot allows a tie-down to be created of any length, even as small as a few inches. Objects A and/or B in the above illustration can be replaced with hooks or other hardware to suit many tie-down applications. The LeverKnot is easily released no matter how much tension is placed on the rope.
