Abstract
ROPE GRIP DEVICE
ABSTRACT
Many knots and splices are in common use to secure a rope around any object or through a ring. The present device eliminates the requirement of a knot and includes a first rope engaging loop and a second rope engaging loop with a pair of legs extending therebetween and the loops extending perpendicularly upwardly from the legs. The dead end of the rope is passed through the first and second loops and then around the member or object to which the rope is to be attached and then back between the legs and the standing part of the rope extending between the loops.

ROPE GRIP DEVICE
BACKGROUND OF THE INVENTION
This invention relates to new and useful improvements in rope gripping devices.
Conventionally, a rope is fastened around an object for towing securing and/or splicing, by means of knots, or hooks on the dead end of the rope engageable over the standing part and the like.
These knots are difficult to undo particularly if the rope is wet and has been under tension and a hook can become a flying object if the rope breaks when under severe tension.
The present invention overcomes these disadvan-tages by enabling a rope to be fastened around objects for towing, securing and/or splicing without the use of knots and furthermore it allows easier removal of the rope if so desired. Rope damage is minimal and the devlce is adapted to enable the rope to extend around various sized objects. ~urthermore it is not bulky as :with chains and clevis or metal hooks and it is relatlvely safe because it does not become a flyiny ob~ect if the rope breaks.
In accordance with the invention there is provided a rope grip device comprising in combination a ~2~
first ring and a second ring and a pair of longitudinally extending legs therebetween thereby maintaining the rings in spaced apart, substantially parallel relationship with one another and perpendicular to the legs.
In accordance with another aspect of the inven-tion, there is provided a combination of a rope having a ~ead end for engaging around an object and a standing part, and a rope grip device comprising in combination a first ring and a second ring and a pair of longitudinally extending legs therebetween thereby maintaining said rings in spaced apart, substantially parallel relation-ship one with the other and perpendicular to the longi-tudinally extending legs, the dead end of said rope passing through said first ring and said second ring, around said object and over the legs and under the stand-ng part of the rope extending between said rings.
Another advantage of the invention is to pro-vide a device which is easily attached and detached from a rope.
A still further advanta~e of the invention is to provide a device of the character herewithin described which is simple in construction, economical in manu-facture and otherwise well suited to the purpose for which it is designed.
, , 7~L
With the foregoing in view, and other advan-tages as will become apparent to those skilled in the art to which this invention relates as this specification ~i proceeds, the invention is herein described by reference to the accompanying drawings forming a part hereof, which ; includes a description of the best mode known to the applicant and of the preferred typical embodiment of the principles of the present invention, in which:

Other materials such as reinforced graphite, plastic and the like may be used.
While this embodiment is satisfactory, it is somewhat di~ficult to manufacture due to the welding requirements and the operation thereof is similar to the preferred embodiment illustrated in Figures 2 through 6.
This embodiment also includes a ~irst ring 16 which extends almost completely through 360 terminating with a relatively narrow space 17 at the base thereof as shown in Figure 2.
A second semi-circular ring 18 is provided spaced and parallel to the first ring 16 and this ring extands through substantlally 180 as clearly shown.
Longitudinally extending legs 19 are provided and extend between the lower ends 20 of ring 16 to the lower ends 21 of ring 18 and it will be seen that this ~2968~1 particular configuration is easily formed from a one piece length of rod with ~ust one weld being required along the len~th thereof at any convenient location dependin~ upon manufacturing consideratlons.
In operation of either of the embodiments, the free end 22 of a natural or synthetic rope 23 is passed through the first ring 16 and through the second ring 18 and then around any object such as vertical pole 2~ shown in phantom in Figure 1. The free end is then passed between the legs 19 and under the standing part 24 of the rope as clearly shown in Figure 6 whereupon tension on the standing part extension 23 will cause the grip to tighten against the object 24 with the rope being secure-ly clamped between the standing part 24 and the legs 19.
As long as tension is maintained on the stand-ing part extension 23, there is no chance of the rope slipping but when tension 1s released, it is easily dis-engaged from the device by loosening the standing part 24 and withdrawing the dead end 22 from between the legs and this part 24.
~ nother advantage is :that it can be used ~o tie-off against an object of any configuration or through a rlng and the length of the standing part 23 is easily :adjusted by passing more of the dead end 22 around the -.

I~ will also be appreciated that little damage will occur to the rope regardless of the tension being applied thereto.
Although dPsigned primarily for use as a substitute for knots, the present device may replace spliced loops, braided eyes and the like on rope ends.
Since various modifications can be made in my invention as hereinabove described, and many apparently widely different embodiments of same made within the spirit and scope of the claims without departing from such spirit and scope, it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense.
