The junction of the ends of fishing line, ropes or other material according to a special scheme is called a knot. Most of the hinges known to man were invented by sailors, the rest are their variations that arose during use. In total, there are about 5 thousand compounds used in various branches of human activity daily.
Depending on the purpose, practical nodes are distinguished by several types:
- grasping;
- shock absorbing;
- auxiliary.
Briefly about the main thing
Grapevine is a complex node. Tying it, a person has no right to the slightest mistake. After all, this can violate the strength that the grapevine (knot) possesses , the pattern and sequence of steps taken during the connection of the two ropes, which can lead to injuries if an incorrectly fixed loop is used.
What do you need to know about the grapevine node?
The node is very popular, but it is often confused with the equally common “eight” or the Turkish loop, the circuit diagrams of which are relatively similar. Therefore, get acquainted with the features and design scheme of "grapevine" in more detail.
You have already read that such a loop is ideal for connecting two threads, ropes, cables. Like any other, “grapevine” is a knot weakening the rope, but compared to similar loops, the attenuation coefficient is 0.95, which means that the rope is only 5% of its strength. It is noted that other types of nodes with such a low attenuation coefficient simply do not exist.
Features of connecting structures
The assembly itself consists of half-nodes - two or three, the main difference between which is the number of turns of thread / rope around one of the ends of the cable. They are tied in sequential order with the free ends of the ropes. The working ends should be no shorter than 12-20 cm. When tying a half-knot, you work only with the end of one rope.
The tourist nodes with the names “fishing knot”, “prusik”, “double simple” are tightly connected by the type of loops with the species we are considering. Having an understanding of how to make the nodes mentioned above, you can definitely cope with loops of a more complex level of knitting. In the process of studying knot diagrams, an understanding comes of constructing certain types of connecting loops. Therefore, pay attention to the drawings and drawings, which show step by step how to make a knot.
Remember! Before you start linking, practice making simpler loops, study elementary tourist sites with names and patterns, gradually moving to more complex ones. With the help of an experienced instructor, try knitting the desired loop. When connecting a grapevine, you must be extremely careful, because even the slightest failure can result in property damage, personal injury or death.
Application area
"Grapevine" - a node used wherever it is possible:
- to bind the ends of the cord (cordlets) to obtain a loop;
- to construct a station where a person performing a rescue operation can go down;
- for self-insurance;
- for combining several pieces of rope together, to obtain a long and strong rope, which may be necessary when climbing (top insurance from the mountain).
The knot differs in scope because it is used wherever a person has the opportunity to work with ropes, ropes, cables or other materials that can be knitted.
With the help of "grapevine" you can connect two threads into a single whole. There are such designs in shipping and in fishing - knots for leashes, and in textile production; in tourism, mountaineering - mentioned earlier, agriculture and animal husbandry, sometimes even in the everyday life of a person.
Advantages and disadvantages
Of the positive qualities distinguish:
- High level of durability. Among all types of connecting nodes up to 58%.
- Reliability.
- No need to fasten the structure with a control loop.
In addition to the above advantages, there are some inherent disadvantages:
- Even having removed the load from the unit, it is still difficult to unravel it.
- Individual people using the knot note the relative difficulty of tying a loop.
- If the permissible load is exceeded, the node begins to creep, but this is not a problem of a certain type of node, but a general property of the loops. Therefore, tying them, leave the ends of a free thread up to 10 diameters of the rope. For example, tying a rope with a diameter of 6 mm, leave up to 10 cm of thread.
How to tie a knot
Learn how to knit a grapevine knot. The knitting method is carried out by analogy with the Turkish loop:
- Prepare two ropes with equal diameters.
- Take the free end of one of them, and when using it, loop around the other end of the thread.
- Heading from the end of the rope to the base, wrap it again.
- Pass this end of the thread in a position parallel to the rope through the holes formed, starting from the base and stretching the end of the thread at the end.
- Tighten the grapevine (knot) firmly and repeat the steps above using the second running end in the same order.
- Pull the threads together and get a full loop.
Following the step-by-step instructions, you will get a strong "grapevine" node. The knitting scheme is depicted in the article.
Note! Tightening ropes of different diameters, thread each of the knots, applying maximum effort to this. In this case, use materials with a difference in diameter not exceeding 40% and with the most similar type of rope fiber.
Untying the loop, the semi-nodes stretch from each other, thereby weakening them. One of the half-nodes is untied, after which the unused end of the rope lying inside the loops is pulled out of the remaining ones and untangled.
How to make a knot like a picture?
To get a neatly designed loop, try to wind the ends of the ropes in opposite directions: the first to you, the second - vice versa. By doing so, you get asymmetric halves of the knot, forming the right aesthetically attractive pattern.
How to learn how to quickly tie a grapevine
Being in extreme conditions, tourists have to fasten the ropes. And here the speed of execution and practical skills in the field of connecting nodes are not the last value. Motor memory can help out when a climber easily creates a mount without even remembering the knot knotting scheme: the fingers themselves know what to do.
To master dynamic skills, use these simple methods to create a grapevine node:
- Use visual memory. Learn the drawings and instructions in sequence. Train repeatedly, tying without prompting. This will help in any situation to quickly recall the process and give an answer to the question of how to make a grapevine node without any special difficulties.
- Remember the exact sequence of movement of the working ends of the thread during the action. Practical work on connecting the ropes creates a special sequence of actions in the head, and the quality and speed of the node depends on the number of repetitions.
Using these two methods, alternating them or combining them into a complex, both the hands and the brain begin to memorize movements, not only when knitting the grapevine knot, but also other no less necessary loops.
Need a reliable connection? Use the node with the lowest voltage level - "grapevine".
"Grapevine" - a knot used in tourism and mountaineering for tying ropes or cables with the same or different diameters. The main advantage of the loop is its reliability, due to which it has earned popularity among extreme lovers and seasoned anglers as a knot for leashes.
