Description

SPORTS KNIFE KNIFE SIBERIAN BEAR-1.

The utility model relates to products like knives, can be worn in a case. Designed for sporting purposes like a throwing knife.

Known Knife economic and tourist Siberian bear according to the description of the invention to the patent of the Russian Federation No. 2091209, class. В 26 В 3/06, published in VI R 27.07.07.97 (1).

This knife can be used in some cases as a sports throwing knife. But there are also disadvantages to using a hunting knife as a throwing knife.

Firstly, a sharp knife blade can injure the thrower arm. Secondly, the hunting knife is not balanced along either the longitudinal or transverse axes.

Thirdly, it is a significant difficulty in performing a throw for the handle.

There are also knives with an adjustable center of gravity or knives with a center of gravity offset to the tip of the knife. But these knives have a significant drawback, namely, low variability, poor noise immunity of the formed motor skill.

This is due to the fact that throwing a knife of this kind (throwing) is carried out mainly by changing the throw angle with a prolonged movement of the hand and varying the direction of movement of the hand.

The purpose of the proposed utility model Sports throwing knife Siberian Bear-1 is to develop the design of a sports throwing knife.

The design of throwing knives for sports purposes is still not known; the creation of such a knife will contribute to the development of sports throwing knives, and moreover, create a new sport.

The essence of the proposed utility model Sports throwing knife Siberian Bear-1 is as follows.

The shape of the knife, its dimensions, as well as the material are selected as a result of numerous experiments and tests of various steels and designs of knives.

The proposed design of the knife is extremely simple, has a symmetrical shape along the longitudinal axis, the center of gravity of the knife relative to the transverse axis is located approximately in the middle of the longitudinal axis. The thickness of the knife has a single thickness, for example, 4 mm.

In relation to existing throwing knives, for example, hunting, the proposed knife has the following advantages:

-first, does not apply to knives and combat throwing;

-secondly, it is extremely simple in design, has a low cost;

Thirdly, despite the apparent simplicity of the design, it has high durability (up to 10 thousand throws of several

straightening by straightening).

- in application when training throwing.

An analogue of the proposed throwing knife for sports throwing Siberian Bear-1, you can take the knife economic and tourist Siberian Bear according to the patent of the Russian Federation No. 2091209 (1).

Figure 1 shows the proposed sports throwing knife Siberian Bear-1, front view in front and from above.

The proposed knife consists of the following parts and represents a blade and a handle made of spring sheet steel with a thickness of, for example, 4 mm, divided into approximately two parts of equal length by two protrusions across the width of the knife. The average width of the blade and handle of the knife is, for example, 30 mm, the width along two protrusions is 34 mm with a total length of the knife, for example, 280 mm, while the center of gravity of the knife is located on the longitudinal axis of symmetry of the knife at a distance of 120 i 2 mm from the start of the handle .

The proposed sports throwing knife can be used to develop the skill of throwing knives regardless of their purpose and allows you to master the following ways of throwing knives:

1. change of throw angle;

2.Changing the length of the lever (arm) during the throw;

3. changing the beginning of the movement of the hand;

4. change the grip of the knife;

Using the proposed knife, it is possible to learn the following methods of throwing a knife:

1. changing the grip of the knife and throwing angle without changing the length of the lever when throwing;

2. changing the length of the lever without changing the grip of the knife, but with a change in the angle of the throw depending on the distance;

- 3 4. changing the length of the lever and changing the grip of the knife at the same time.

The proposed shape and design of the knife allows you to quickly and efficiently master the above methods of throwing knives, create a new sport - sports throwing knives.
