DETAILED DESCRIPTION

(13) The present invention provides a safe, metal-free and hook-free winch rope system. The discussion herein refers to winch ropes configured with features of the invention as a Safe Metal Free and Hookless Winch Rope, even if the entire length of the winch rope does not incorporate features of the invention. Indeed, as will be clearer from the following discussion, a section of Safe Metal Free and Hookless Winch Rope can be spliced onto the end of an existing synthetic winch rope thereby converting a conventional winch rope into a winch rope that is metal free and hookless.

(14) The invention is described by reference to various elements herein.

(22) Overview

(23) The apparatus of the present invention, in an exemplary embodiment, is a winch rope configured to be selectively attached at one end to an object for the purpose of winching, without using any metal shackles or hooks. In other exemplary embodiments, both ends of the line have the same or similar looping system, as being better suited as a kinetic energy rope or tow rope. It is noted that the terms “rope” and “line” are used interchangeably in this disclosure. Although this disclosure has described using the present invention in the context of off-road driving, four-wheeling vehicles, ATVs, etc., this specific application is not intended as limiting, since the winch rope system of the present invention would be beneficial in many other applications including, for example, construction, rigging, logging, towing, sailing, and other activities in which winches are commonly employed. Therefore, even though the following description uses the term “winch rope”, this terminology is not intended as limiting the invention.

(24) Ropes made of synthetic materials have become popular in recent years for winching because such synthetic lines are lighter, stronger, and more flexible than corresponding diameter steel cable lines. Synthetic ropes or lines are made of synthetic fibers woven together in braided-style that permits openings to be made in-line with the rope using techniques well known in the art of rope making and a tool called a fid to be described shortly. Materials commonly used to make synthetic fibers for synthetic ropes include polypropylene, polyesters, nylon, UHMWPE (UltraHigh Molecular Weight Polyethylene) and Aramids such as Kevlar®, Technor®, and Vectran®, but the present invention does not rely upon any specific material choice.

(25) Apparatus

(26) FIG. 1 illustrates the inventive apparatus 100 in accordance with an exemplary embodiment of the invention. In particular, FIG. 1 illustrates a winch line system 100 that includes a winch rope 102 of, for example, 100 feet or more. The winch rope 102 has a proximal end to be attached to a winch and a distal end 104. A stopper knot 106 is tied at the distal end 104 of the winch rope 102. The stopper knot 106 may be any style of knot capable of holding a loop of line material when the line is under tension. In one example, the stopper knot 106 is a button knot. There are many methods for tying button knots, including, for example, the Chinese button knot, the Celtic button knot, and the monkey fist. The Ashley Book of Knots contains over a hundred examples of button knots. However, it is also noted that any knot that could serve as a stopper knot can be used. Thus, even if the term “button knot” is often used in this description, the present invention is not intended as being limited to this single knot type since a number of different stopper knots are known in the art.

(27) A plurality of openings 108 are formed along the length of the winch rope 102 proximal to the stopper knot 106. In one example, the openings 108 are Brummel style openings. Brummel style openings are individually formed using a fid, which is a conical tool with a dull point, traditionally used to work with rope and canvas in marlinespike seamanship. The end of the fid opposite the dull point has a longitudinal cavity into which a tip end of a rope is inserted, and then the dull point is used to penetrate laterally through the braided layers of the rope. When the fid is pushed/pulled through the rope, the end of the rope inserted in the fid cavity also gets pushed/pulled laterally through the rope and can then be inserted, again using the fid, lengthwise along the interior of the rope, to internally secure the end of the rope inside the rope. One technique of using a fid to splice into a rope is known as a locked brummel splice and is well known in the art of rope making. However, other splices are well known in the art, so the present invention is not limited to this single splicing technique. The brummel style openings 108 shown in FIG. 1 are formed by splicing each end of a short segment of rope into the main rope using a locked brummel splice, such that the two ends of the rope segment get fused into the main rope via a locked brummel splice at each end.

(28) FIG. 1 exemplarily shows three brummel style openings 108 formed inline along the winch rope 102, but it should be clear that any number of such openings could be formed along the length of the winch rope 102.

(29) The winch line system 100 of FIG. 1 includes a separate rope section 110 having brummel splices 112, 114 on each end. Since the two brummel splices 112, 114 are large enough for the stopper knot 106 to pass therethrough, the rope section 110 can be separated/detached from the winch rope 102. When attached to the winch rope 102, the rope section 110 can be easily wrapped around an object by merely slipping brummel splice 112 over the stopper knot 106, wrapping the rope section 110 around the object to be hitched, and then slipping the other brummel splice 114 over the stopper knot 106. Tightening the winch rope 102 will draw the two brummel splices 112, 114 against the stopper knot 106. One of the benefits of this system 100 is that the separate rope section 110 can be easily replaced if damaged.

(30) FIG. 2 depicts another embodiment of a winch rope 200 that is similar to the embodiment in FIG. 1, but does not include the separate rope section. In particular, the winch rope 200 includes an elongate rope having a distal end 202. A stopper knot 204 is tied in the distal end 202 of the rope 200. Openings 206 are formed along the length of the rope 200 proximal to the stopper knot 206.

(31) FIG. 3 shows a variation in which the winch rope 300 has a locked brummel splice loop 302 formed at the tip of the winch rope 300, with a button knot 304 formed a predetermined distance from the tip, and brummel style openings 306, 308 are then formed at predetermined distances inline along the rope 300. The locked brummel splice loop 302 can slide over the button knot 304 to form a self-tightening loop that acts as a hook or shackle which needs no metal components or external pieces to function. It should also be clear that the button knot 304 could also be inserted through inline brummel style opening 306 to wrap around a smaller diameter object such as a small tree trunk or through inline brummel style opening 308 around a larger diameter object such as a larger tree trunk. Additional inline brummel style openings could be incorporated along the length of the winch rope 300 or a predetermined portion of the rope length.

(32) For example, in the exemplary configuration shown in FIG. 3, with inline openings (e.g., 306, 308) in the rope approximately every 12 inches, a button knot 304, and an additional loop 302 coming out of this button knot 304 on the end, and a stopper to keep the end from sucking into the winch fairlead. These components are connected as follows: starting at the beginning of the winch line there is a standard winch rope of 100 feet, every foot of rope there is an opening (e.g., 306, 308) where the button knot 304 at the end of the rope can be inserted to form a closed loop for winching. Thus, at the end of the winch line there is a large button knot 304 that is used to insert in these openings 306, 308 in the winch rope, to form a closed loop without using any metal parts. Also coming out of this button knot 304 on the end of the winch rope, in this exemplary embodiment, is another foot of rope with a loop 302 in the end, and its use is to hook onto the end button knot 304 for hooking onto smaller objects for the same reason of making a closed loop for winching purposes. It should further be noted that when the button knot 304 at the end of the winch line goes through any of the openings 302, 308, 306 in the winch line and tension is applied, the tension on the winch line acts as a closing device and keeps the knot from slipping out of the opening.

(33) In one embodiment, a second stopper knot may be made available on the proximal end of the line.

(34) FIG. 4 shows an exemplary embodiment with the locked brummel splice loop 404 slid over the button knot 402, as well as the two inline brummel style openings 406, 408. Additionally, FIG. 4 shows at points 410, 412 how an end section of rope having a button knot and a plurality of brummel style openings could be spliced/tapered into an existing winch rope 414. FIG. 4 thereby demonstrates how the present invention can be incorporated into an end of an existing winch rope 414 using a splicing technique in which the added rope segment containing the safe metal free and hookless winch rope of the present invention is tapered at the end and then spliced into an existing winch rope by burying it inside a length of the existing winch rope 414, using a fid tool.

(35) FIG. 5 shows in detail a variation in which a small closure mechanism is incorporated at the end of the Safe Metal Free and Hookless Winch Rope invention. Button knot 502 is tied on the end of the device, and the self cinching loop mechanism 504 slides over the button knot 502 and self tightens under winching loads. Loop 504 slides over button knot 502 to enclose small areas such as a winch receiver or some other solid winch point. Point 506 shows where the loop 504 is sewn through the rope itself. Label 508 shows the other end of the rope leaving the button knot 502 and being spliced into the main rope by weaving through the interior of the main rope in a locked brummel manner. This locked brummel technique keeps the rope from slipping or coming apart by using friction to keep itself secure inside the interior of the main rope.

(36) FIG. 6 shows a mid vantage view of the exemplary winch rope device shown in FIG. 5. Button knot 502 secures the end of the rope and creates the “hook” that can be inserted in any opening including loop 504 to wrap around small objects, loop 510 to wrap around medium sized objects, and loop 512 to wrap around larger objects. It should be clear that more openings could be added to the rope in locations that are proximal to the opening 508 to provide the ability to wrap around larger object sizes.

(37) FIG. 7 shows a close up view of the end of the metal free winch rope device of FIG. 5, including a close up view of button knot 502. Label 514 shows the locked brummel splice protruding from the button knot 502 and continuing down the main rope. Label 516 shows the loop making its way back around to the other side of the button knot 502.

(38) FIG. 8 shows in closer detail the knotting and splicing of the winch rope device shown in FIG. 5. FIG. 8 shows the button knot 502 from the opposite side of the knot from that shown in FIG. 7. FIG. 7 shows the routing of the button knot 502, and label 514 shows a close up of the two ropes as they exit the button knot 502 and merge together in a splice, one rope inside the other.

(39) FIG. 9 shows in detail the button knot 502 which becomes the so-called “hook” when it is placed through the openings in any other loop part of the winching rope.

(40) FIG. 10 shows the split loop 506 of the exemplary configuration shown in FIG. 5, as one side pierces the other forming a self-tightening loop that engages the button knot 502 in a way that it cannot come apart when under load.

(41) FIG. 11 shows a close up of the inline loop openings, such as 108 in FIG. 1, and 206 in FIG. 2, 306, 308 in FIG. 3, 406, 408 in FIG. 4, and 510, 512 in FIG. 6. As briefly explained earlier, in making a brummel style loop opening, rope 1002 penetrates through rope 1004, which is then spliced into the interior of rope 1004, and similar penetrating and splicing occurs at the other end of the loop opening. With the two ropes 1002, 1004 splicing through each other, a locking force is formed which keeps the loop in place without collapsing on itself. The loop opening will always be able to accept the button knot shown in FIG. 9 as the loop will never slip closed when there is slack in the rope. Yet, when pulling pressure is applied on the rope, the loop will close and the button knot will not be able to escape the loop.
