Perhaps the owners of automobiles are best acquainted with the action of such elements. The rubber bushings of the rear shock absorbers are parts that change quite often. However, to the surprise of many, the scope of use of rubber products is much wider.
What is donka?
A rather unexpected way for many to use shock absorbers was fishing. However, they are used, of course, not in all types. That is, there is no reason to use rubber in ordinary fishing rods. However, it is worth a little talk about what donka is. This is a way of catching fish that lives on the bottom. With the help of ordinary fishing rods, you can catch only the prey that swims to the surface to find feed. Most eat what is at the bottom. For this reason, this method of fishing, such as donka, is considered one of the most catchy. However, to use this method, it is necessary to acquire special equipment, which also includes a rubber shock absorber.
The essence of the donkey and the use of shock absorbers
As with any method, this also has a drawback. The main disadvantage here was that getting tackle to the same place is quite problematic. For this reason, it was necessary to develop an improved tackle, which allowed you to get to the same place with an accuracy of several centimeters.
It is worth noting here that the main element that was needed was the rubber shock absorber. Donka with this device was invented a long time ago and was used, as well as sold back in the Soviet Union in fishing stores. Here we can say that those who did not want to buy such things in special outlets purchased rubber tows in pharmacies, and then dismissed them onto shock absorbers. However, there are also some disadvantages. Rubber rubbed pretty quickly, and then torn. If this happened when the load was lowered to the bottom, then the lead that was at the end also remained there. Because of this, this method, as well as this use of rubber shock absorbers, has not become too popular.
Assembly donkey with rubber
You can assemble such fishing tackle for fishing with your own hands, if you still want to try it in action. To do this, you will need a fishing line, a rubber shock absorber, a lead load, a fishing line, hooks, a piece of foam, a reel.
About the rubber part is worth telling more. In this case, it is necessary to have a rubber band on hand, the cross section of which will be round or square. The diameter must be at least 3 mm. Most often, such a device can be purchased at a fishing store. The shock absorber is sold in segments of 5, 10, 15 and 20 meters.
Sports application
In the sports world, rubber products have also found their application. Athletes call such devices expanders. At its core, these are Bubnovsky’s rubber shock absorbers. These tools have been successfully used for sports at home. Properly applying them, you can work out almost any muscle group.
In its appearance, the rubber shock absorber for fitness resembles a tape at the ends of which there are handles to make it comfortable to hold in your hands. The tension force of rubber in such devices replaces the load that athletes use in the gym. In some cases, this parameter can be adjusted. For athletes of a higher class, sometimes one rubber shock absorber is not enough, and therefore it is allowed to use two at once. Another important note: the expanders for the legs and for all other muscles are two different devices.
Using rubber in foot expanders
There are several varieties of this device. Although the basis here always remains the same - this is the use of rubber shock absorption:
- The first type is a tubular type of device with handles. This device is often called a shock absorber. The device is a long rubber band, at the ends of which there are triangular handles. It can be used by both women and men.
- The second type is the tape type. The rubber shock absorber used here in the form of a tape is suitable for working not only with the muscles of the legs and arms, but also of the back. It is worth adding that it is this option that is used in the training of Bubnovsky.
- The third type is expanders with a protective sleeve. It is also called a rubber shock absorber with cuffs. The main purpose of this device is the development of only the leg muscles. The bottom line is that you need to effortfully stretch the spring, which pulls in the opposite direction with the help of rubber shock absorption.
- The fourth species is the butterfly or figure eight. Both tools are used to develop an athlete’s strength.
In the end, it is worth adding that there are rubber shock absorbers in hand expanders. They are also distinguished by several species.
Plug fishing
If in the previously considered version, rubber products were not used directly to collect fishing rods, then in this embodiment, everything is somewhat different. This method of fishing, like plug, provides for the mandatory use of depreciation. To understand how a fishing rod with a rubber shock absorber is assembled for such fishing, you need to know the design of the device.
Start with the fact that all the knees of the plug are hollow. The shock absorber, in the role of rubber, is stretched in the upper knees of the device. The main function of such a product in this case is to mitigate or completely eliminate shock loads throughout the entire length of the fishing rod. These loads occur at the moment when the fish are being fished.
Most often, latex or full elastic is used as a rubber shock absorber in this design. If the first option is used, it is best to use a tourniquet with a solid diameter cross section from 0.5 to 2.5 mm.
Use of elastic shock absorbers
If it was previously said about the use of rubber in expanders, then the use of such products is somewhat different. To explain the principle of operation of elastic bands, which are most often made of rubber, we can give an example of the impact of chains worn on a bar.
When an athlete performs, for example, a bench press, you will notice that chains are thrown around the edges of the neck. The bottom line is that the more the chain straightens, the harder it is for a person to lift it. In addition, when lowering the weight back, you also have to put a lot of effort. This is necessary so that under the weight of all the same chains it does not fall on the chest.
The use of elastic shock absorbers is similar to the operation of chains. The only thing needed is to equip the mount on the floor along the edges of the bar. If you throw rubber shock absorbers on the projectile and lift it, the same thing will happen as in the case of chains.
Having considered all these options, we can conclude that the use of rubber and its quality of depreciation is quite widespread, and in a wide variety of areas of human activity.
