BACKGROUND
Various aspects of the present invention relate generally to a harness for pulling a sled, and more particularly to a harness with a braided lead that can be used as a safety device.
When going ice fishing, a fisherman loads equipment (e.g., portable shelter, gear, lights, etc.) onto a sled to transport the equipment to a fishing site. To pull the sled, the fisherman may tie a rope to the sled.
BRIEF SUMMARY
According to aspects of the present disclosure, a harness comprises two limb loops created from a harness knot coupled to a lead via the two limb loops of the harness knot at a first end of the lead. The lead is a braided lead, and a single-bowline knot creates a single-bowline loop at a second end of the lead. Further, a removable fastener prevents the braided lead from unbraiding and is removably coupled to the lead in a final loop of the braided lead and removably coupled to the two limb loops of the harness knot. Moreover, the limb loops, lead, and single-bowline loop are made from an integral piece of rope. The braided lead does not unravel while the removable fastener is in place. However, when the removable fastener is removed, the braided lead may unravel to create a rescue rope with a harness.

DETAILED DESCRIPTION
According to various aspects of the present disclosure, a harness with a braided lead includes two limb loops made from a harness knot at a first end. Further, the harness with a braided lead includes a single-bowline knot creating a single-bowline loop at a second end. Thus, the braided lead is between the harness knot and the single bowline knot. Moreover, the limb loops, braided lead, and single-bowline loop are all created from a single piece of rope.
Turning now to FIG. 1, a first embodiment of the harness 100 made from a single piece of rope is shown. While any length of rope and thickness of rope may be used, preferred embodiments of the harness 100 (and 200, FIG. 2) use fifty feet (approx. 15.25 meters) of rope with a thickness of ⅜ inch (approx. 1 centimeter). Again, the rope may be made from any suitable material (e.g., synthetic (polypropylene, polyester, etc., combinations thereof), natural, organic, etc., combinations thereof), but preferred embodiments are made from polypropylene rope. A first end of the rope is tied in a harness knot 102 having two large loops (e.g., a double-bowline knot, a Spanish-bowline knot, a parallel-bowline knot (as described herein), etc.): a first limb loop 104 and a second limb loop 106. The limb loops 104, 106 may be any length that is suitable for a user to place his or her arms through. In preferred embodiments, each limb loop 104, 106 is approximately four feet (1.2 meters). The harness knot 102 is held in place with a stopper knot.
At a second end, the harness includes a single-bowline knot that is inverted creating a single-bowline loop 114. The single-bowline loop 114 can be any length, but in the embodiment of FIG. 1, the single-bowline loop 114 is about three inches (7.6 centimeters) in length. With about 50 feet of rope, the length of rope between the single-bowline knot and the harness knot 102 is about 41 feet (12.5 meters). That length of rope is braided (i.e., tied) in a series of daisy-chain knots (i.e., a chain sinnet) beginning at the single-bowline knot to create a braided lead 118.
A tag end of the single-bowline knot is held in place by a first daisy-chain knot which holds the single-bowline knot permanently in place. The daisy chaining repeats, which forms the braided lead 118, where the length of the braided lead is approximately 20% of the length of rope between the harness knot 102 and the single-bowline knot. For example, in the embodiment of FIG. 1, the 41 feet (12.5 meters) of rope condenses down to approximately eight feet (2.4 meters) of braided lead 118. A final daisy-chain knot is held in place by a removable fastener 122 (e.g., a carabiner) that hooks from the final daisy-chain knot loop to the limb loops 104, 106 of the harness knot 102.
A second removable fastener 124 (e.g., carabiner) is added to the single-bowline loop 114 to allow attachment to a load (e.g., sled). In some embodiments, the single-bowline loop 114 couples to the load without a need for the second removable fastener 124.
FIG. 2 illustrates a parallel-bowline knot 250 that may be used as the harness knot (102, FIG. 1), as described herein. To make the parallel-bowline knot 250 from a rope 252, a user doubles over the rope such that two sections 254, 256 of the rope 252 in the user's hand run parallel to each other. Then, the user ties a bowline knot with this configuration, which results in two large loops (see 104, 106FIG. 1) and a smaller “tag loop” 258. The tag loop 258 can be ignored/minimized, or the tag loop 258 can be wrapped around the knot 250 to help secure the knot 250 and prevent the knot 250 from coming untied or slipping under extreme loads.
Further, as shown in FIG. 2 a fastener (122, FIG. 1—e.g., a carabiner as shown in FIG. 2) clips between a final daisy-chain knot loop 260 and the two loops of the parallel-bowline knot 250 (as discussed above).
Turning now to FIG. 3, a second embodiment of the harness 300 is shown. The second embodiment 300 is similar to the first embodiment 100 (FIG. 1) except the single-bowline loop 114 is larger in the second embodiment 300. For example, the single-bowline loop 114 of the second embodiment 300 may be eight feet (2.4 meters) long. In the second embodiment 300, the single-bowline loop 114 is cut, creating a first line 330 and a second line 332. In some embodiments, each line 330, 332 is coupled to a removable fastener 340, 342, respectively, via inverted single-bowline knots to couple to the load. In other embodiments, the removable fasteners 340, 342 are not required, as the lines can couple directly to the load.
The embodiments of the harness 100, 300 discussed above in FIGS. 1-3, as well as other embodiments, may be coupled to a load (e.g., an ice-fishing sled). A user can put their arms through the limb loops of the harness to wear the harness like a backpack. The user can then pull the load more easily by utilizing their full body weight with no hands required. Further, in case of emergency (e.g., someone falling through ice of an ice-fishing spot into icy water—i.e., a victim), the user can quickly remove the removable fastener 122 that hooks from the final daisy-chain knot loop to the limb loops 104, 106 of the harness knot 102. The braided lead 118 can then be unraveled to its full length (instead of the condensed length) in a few seconds. The user can then throw the unraveled lead and limb loops of the harness to a victim from a safe location up to approximately forty feet away (based on a fifty foot rope) to assist the victim out of the icy water. Other lengths of rope allow the user to be different distances away based on the rope length. Therefore, the user can stay at a safer distance to rescue the victim rather than getting too close to where the victim fell through the ice, which could result in the user falling through the ice as well. Thus, the harness with a braided lead functions as a pulling device and a safety rope. Further, except for the attachment devices, the entire harness (loops and lead) can be made from a single, integral piece of rope, which allows the harness to be unraveled to a longer distance without a need to splice together ends of separate ropes.
