Description

The utility model relates to sports equipment, with which the puck is moved around the court or field, in particular for ice hockey, and can be used as professional hockey equipment during player training and games.

Currently, significant changes in the shape of parts of a hockey stick mainly concerned the stick. These changes were designed to better control the puck and make it easier to lift it from the playing surface. However, there are a small number of technical solutions for improving the shape of the handle of a hockey stick.

Most hockey stick handles are made straight, which has a number of disadvantages. For example, when throwing, the handle bends in the opposite direction from the washer, a negative angle appears, which reduces the accuracy of the throw, as well as its strength and speed. In addition, there is an increased return to the player’s hands. When throwing from an uncomfortable hand, on straight arms, the supporting left hand is farther away from the body and cannot create the lifting force of the required magnitude to lift the washer up.

To correct the shortcomings of a stick with a straight handle, the prior art designs of clubs, the handle of which has some bend along its length.

Known stick for ice hockey [Patent application US13 / 716292 from 12/17/2012, publ. US2014 / 0171237 from 06/19/2014, IPC (2006.1) A63B59 / 14], the handle of which is concave along the entire front surface without any inflection points, and is also convex along the entire rear surface without any inflection points. In this case, the deviation of the bend from the upper and lower end parts is equal.

A disadvantage of the known device is the lack of indication of the direction of the bend and its maximum deviation.

A hockey stick was selected as a prototype [Patent US4629190, publ. 12/16/1986, prior. from 04.17.1984, IPC ⁴ A63B59 / 14], containing a pen and a handle having an arcuate bend between the upper and lower ends in a plane perpendicular to the plane passing through the club pen. The bend of such a handle reaches the point farthest from the chord, passing between the upper end of the handle and the heel of the pen, at a distance of 33⅓% to 70% of the length of the handle, measured from its upper edge, preferably in the range of 55-60% of the length. The bend is made in a plane perpendicular to the plane of the blade, and such that the handle is deflected from the chord by an angle of 4 ° to 16 ° in the upper part of the handle and by an angle of 5 ° to 20 ° in the lower part of the handle. If the handle is used for a composite club (the handle and feather are made in separate parts), the lower part of the handle from 17.78 to 22.86 cm long is made straight with an additional section adjoining it to go from the straight part of the handle to the curved one.

One of the disadvantages of the known prototype device is that the maximum value of the bend depends on the length of the handle, while the bend is not uniform over the entire length with different deviations of the bend from the upper and lower parts of the handle, which significantly reduces the reliability of the hockey stick during operation.

Thus, during operation, the known device with a curved handle and the device of the prototype have insufficient reliability indicators due to the uneven load on the bend of the handle and too large a deviation, which increases the likelihood of a hockey stick breaking during the game.

In addition, clubs with a curved handle of known configurations cannot be effectively used for athletes of different stature and playing position, which means they are not universal. So, when adjusting the length of the clubs by cutting them and / or grabbing the clubs in the places where their handles are bent, they acquire the disadvantages of a traditional stick with a straight handle, and the bend acquired by the handle during the throw also brings the shape of the known hockey sticks closer to the straight line due to the center shift bending. In addition, when the athlete grabs the handle, the curved part is involved, which reduces the effectiveness of the bend.

The technical problem to which the claimed utility model is directed is to create a universal hockey stick that can be used by athletes of different height and playing position.

The technical result, which is achieved by the claimed utility model is to provide the ability to adjust the length of the handle for athletes of different heights and impact forces without changing the configuration of the bend.

The essence of the claimed hockey stick is as follows.

A hockey stick contains a feather and a handle interconnected, which is made with an arcuate bend, the handle is made concave on the front surface connected to the upper surface of the feather, and convex on the rear surface connected to the lower surface of the feather. Unlike the prototype, the deviation angles of the bend from the upper and lower end parts of the bend are respectively equal, and the upper end part of the bend passes into the upper straight part, which is made in length from 5 to 20% of the length of the bend.

Bending depth is the radius of curvature of the arcuate bend of the handle.

The bending depth at the central bending point of the handle is preferably from 0.5 to 6 cm.

Depending on the magnitude of the depth of the bend of the handle, the characteristics and purpose of the handle and the entire hockey stick as a whole change. A bending depth of 3 to 6 cm is preferable for the equipment used in training athletes, since it requires the application of a greater force in comparison with other intervals, which develops the necessary game qualities, such as, for example, endurance. Accordingly, the execution of the bending depth in the range from 0.5 to 3 cm is preferable for game equipment due to the relatively small magnitude of the force applied during the throw. The most preferable for playing equipment is the interval of bending depth at the central point of the bend of the handle from 1 to 2 cm, which allows to achieve optimal characteristics of the handle and hockey stick as a whole due to the relatively small shoulder and load on the player.

According to the claimed hockey stick, the upper end of the bend goes into the upper straight part, which is made in length from 5 to 20% of the length of the bend. Due to this, when capturing the handle of the claimed device, the bend remains working, while maintaining the advantages of its curvature. In addition, this design of the upper straight part allows you to adjust the length of the handle for athletes of different stature and impact strength while maintaining the full length of the bend, without changing the configuration of the bend, and therefore the gaming characteristics of the claimed hockey stick as a whole.

Thus, it is possible to effectively use straight sections to adjust the length of the handle, without reducing its playing qualities.

Preferred lengths of the upper straight part are determined experimentally. When the length of the upper straight part is less than 5% of the length of the bend, a sufficient length of a small section is not provided for regulating the length of the handle, which makes it necessary for the player to use the bending of the handle as a section for fixing the position of the hand. When performing the length of the upper straight part of more than 20%, the characteristics of the hockey stick deteriorate, bringing the handle of the inventive hockey stick closer to the straight handle of a standard hockey stick.

In addition, the upper straight part in the bending direction can be further provided with a deviation of the upper straight part from 70 ° to 80 °, preferably 71 °, allowing a smooth transition from the straight part to the curved.

The lower end of the bend according to the inventive hockey stick can go into the lower straight part, which is preferably made from 5 to 15% of the length of the bend, which provides the most reliable connection between the handle and the pen. Preferred lengths of the lower straight portion are determined experimentally. When performing the length of the lower straight part of less than 5% of the length of the bend, the reliable fastening of the handle to the pen is not ensured, since the contact length is small. When performing the length of the lower straight part of more than 15%, the characteristics of the hockey stick deteriorate, bringing the grip of the inventive hockey stick closer to the straight handle of a standard hockey stick.

The lower straight part in the bending direction can be further provided with a deviation of the lower straight part from 95 ° to 125 °, preferably 114 °, allowing a smooth transition from the straight part to the curved.

The deviation of the lower straight part and the deviation of the upper straight part allow for a smooth transition from the lower straight part or the upper straight part to the bend, respectively, which increases the reliability of the handle of the claimed hockey stick.

The inventive hockey stick with a handle having the claimed bend configuration has optimal gaming characteristics, such as the reliability of the equipment and the magnitude of the force applied to the throw, with the ability to adjust them within the given intervals depending on the goals of the equipment. Moreover, the handle length of a hockey stick can be adjusted for a particular player without losing these advantages due to the upper straight part.

The design of the utility model is illustrated by the drawing:

FIG. 1 is a schematic illustration of a hockey stick.

The hockey stick contains a connected feather 1 and a handle 2. The handle 2 has a front surface 3 and an opposite rear surface 4. The handle 2 is made with an arcuate bend 5, while the angles A and B deviation of the bend 5 from the upper and lower end parts of the bend 6 and 7 are respectively equal.

Pen 1 has the upper surface of pen 8 and the opposite lower surface of pen 9. The front surface 3 of the handle 2 is connected to the upper surface of the pen 8, and the rear surface 4 of the handle 2 is connected to the lower surface of the pen 9.

The handle 2 is made concave on the front surface 3 and convex on the rear surface 4.

The depth of bend 5, measured from the chord passing between the upper and lower end parts 6 and 7, respectively, to the farthest point of bend 5, that is, at the central point B of bend 5, is G.

Hockey stick made of carbon fiber.

The upper end part 6 of the bend 5 passes into the upper straight part 10, which is made of a length D from the length of the bend 5. In addition, the upper straight part 10 in the direction of the bend 5 is provided with a deviation 11 of 71 °.

The lower end part 7 of the bend 5 passes into the lower straight part 12, which is made of a length E from the length of the bend 5. The lower straight part 12 in the direction of the bend 5 is provided with a deviation 13 of 114 °.

The principle of operation of the claimed device is as follows.

Adjusting the length of the handle 2 is carried out by cutting the upper straight part 6 or by placing the player's hands on the site of the upper straight part 6.

Consider the throw using the claimed hockey stick, where the supporting arm is left, the throw is made from a comfortable hand, the player’s hands are at different levels of the handle 2. When swinging, the body mass transfers the load to the handle 2 through the hands, it bends depending on the player’s strength (mass) .

When throwing from an uncomfortable hand, the supporting left hand, due to the configuration of the bend 5 of the handle 2, is closer to the body, which leads to a more convenient vertical throw from the goal line.

To confirm the achievement of the technical result in the declared intervals, studies were conducted on the basis of five selected private performances of the claimed hockey stick, the characteristics of which are presented in table 1.

The experiments showed that the behavior of the hockey stick during its operation was consistent with the predicted.

Execution 1. The bend acquired during a throw is close to the occurrence of a negative angle and, consequently, to a deterioration in the accuracy, speed and strength of the throw, an increase in the return of the hockey stick to the player’s hands. There is a noticeable return in the opposite direction to the player’s hands. The length of the upper straight part 10 is insignificant, the adjustment of the length of the handle 2 can be carried out in a small amount. The length of the lower straight part 12 is small, which determines the unreliability of the connection of the handle 2 and pen 1.

Execution 2, 3, 4. During the throw, a negative angle does not occur, there is no corresponding deterioration in the accuracy, speed and strength of the throw, increase in the return of the hockey stick to the player’s hands in the opposite direction. The reliability of the handle 2 is high. The return on the player’s hands is negligible. The length of the upper straight part 10 allows you to adjust the length of the handle 2. The length of the lower straight part 12 allows you to ensure a reliable connection of the handle 2 and pen 1.

Execution 5. During the throw, a negative angle does not occur, there is no corresponding deterioration in the accuracy of the throw. The reliability of the handle 2 sharply decreases. The length of the upper straight part 10 allows you to adjust the length of the handle 2, however, the accuracy, speed and power of the throw are significantly impaired. The length of the lower straight portion 12 significantly impairs the accuracy of the throw.

Thus, the claimed utility model allows to achieve the following technical result - providing the ability to adjust the length of the handle for athletes of different stature and impact strength without changing the configuration of the bend.
