Abstract

The invention relates to sports equipment for playing hockey, principally for playing ice hockey. The task solved by the claimed invention is to simplify the design, to improve the reliability and the playability. The ice hockey stick includes a handle and a blade made as a U-shaped clamp with a flexible element made as a plate installed in the clamp plane and fixed between the clamp sections. Innovation of the proposed stick is execution of the plate with variable pressure along its length, installed in the clamp plane, with a capability of bending to both lateral sides; at this time, the plate ends are coupled with the clamp sections. This coupling can be rigid as a dovetail joint or mobile, for example made using articulated joints. A combined version is possible; in this case, the plate end from the handle side is rigidly fixed, and from the stick tip it is mobile, i.e. hinged. Moreover, the plate ends in the area of fastening to the corresponding clamp sections have flexibility equal to the flexibility of the stick handle; and the plate part located between the clamp sections has the flexibility corresponding to the allowable deflection; at this time, the plate is made of gradient polymer material with preset gradient of elastic modulus along the length.

Description

The invention relates to sports equipment for playing hockey, mainly ice hockey.

Known hockey stick for playing ice hockey, containing a handle and a hook, made in the form of a U-shaped bracket with an elastic element fixed between its branches [1].

The disadvantage of the known club is the possibility of slipping and sticking of the washer between the links of the elastic element, as well as the uncontrollable rebound and inconvenience of guiding the washer.

A well-known hockey stick containing a handle and a hook, made in the form of a U-shaped bracket with an elastic element fixed between its branches, the latter is made in the form of a plate installed in the plane of the bracket with the possibility of reciprocating movement relative to one of its branches, while the ends of the plate connected to the branches of the bracket, and the end of the plate from the side of the handle is connected by means of springs with the corresponding branch of the bracket, which has a vertical groove to accommodate the end of the plate, and the opposite branch of the bracket is connected to the end of the plate by means of a hinge [2].

The disadvantage of the known club is the complexity of the design, low reliability due to the possibility of the plate getting stuck in the groove due to distortions, stretching and breaking of the spring, as well as the increased risk of injury, which allows it to be used only as a simulator.

The object of the invention is to simplify the design, improve reliability and improve play properties.

The task is achieved by the fact that in a stick for playing ice hockey with a puck containing a handle and a hook made in the form of a U-shaped bracket with an elastic element fixed between its branches in the form of a plate having variable elasticity along the length, installed in the plane of the bracket with the possibility deflection in both lateral sides, while the ends of the plate are connected by the branches of the staple by means of hinges or rigidly by means of a dovetail connection. Depending on the task to be performed, an embodiment is possible in which the end of the plate on the side of the handle is rigidly connected to the corresponding branch of the staple by means of a dovetail connection, and the opposite branch of the staple is connected to the end of the plate by means of a hinge. In this case, the ends of the plate in the area of attachment to the corresponding branches of the bracket have elasticity equal to the elasticity of the club handle, and the part of the plate located between the branches of the bracket has elasticity corresponding to the allowable deflection, and the plate is made of a gradient polymer material with a given gradient of the elastic modulus along the length.

The implementation of the hockey stick for playing ice hockey from two elements greatly simplifies its design and transfers it from the simulator to the playing field, and the implementation of the main element of the hook in the form of a plate having variable elasticity along the length, installed with the possibility of bending in both directions, increases reliability and improves the playing properties of the club. Various options for attaching the plate to the branches of the bracket expand the functionality of the stick and allow you to adapt its use as forwards, defenders, goalkeepers, as well as when executing free throws (shootouts) in the process of manipulating it at various points of the playing court.

The implementation of a plate made of a gradient polymer material with a given modulus of elasticity along its length and in the areas of attachment to the branches of the bracket allows you to adapt the stick for both anthropological (height, weight), physical (strength, grip), functional (right, left, center, goalkeeper) parameters players, as well as for age (children, youths, adults, masters) and corresponding weight, size and other technical characteristics of hockey sticks for different categories of competitions, as well as increase reliability due to uniform wear of friction units in articulated joints.

If the plate is damaged during the game, it can be easily removed from the hook branches and replaced with a spare one, which increases maintainability and durability.

As a composition for making a plate, you can use a composition for a gradient polymer material [3], which is used as a structural material with a wide range of continuous variation of the modulus of elasticity along the length.

The essence of the invention is illustrated by a drawing:

in fig. 1 shows a general view of the proposed club;

in fig. 2 the same, longitudinal section;

in fig. 3 is the same, view A in FIG. 1 for hinged plate ends;

in fig. 4 is the same, view A in FIG. 1 with hinged and rigid fastening of the ends of the plate;

in fig. 5 the same, view. And in FIG. 1 with rigid attachment of the ends of the plate;

in fig. 6 position of the plate at the moment of stopping and throwing the puck.

The stick consists of a handle 1 and a hook 2, made in the form of a U-shaped bracket, with an elastic element 3 fixed between its branches in the form of a plate having variable elasticity along the length, while the plate is installed in the plane of the bracket with the possibility of bending in both directions, and the ends of the plate are connected to the branches of the staple. Depending on the functions of the players and the tasks performed, the connection of the ends of the plate with the branches of the bracket can have several versions, for example, with the help of hinges for the sticks of attackers and defenders, a rigid connection of the dovetail type for goalkeeper sticks or combined, i.e. rigid in the heel of the hook and articulated in the toe of the hook for performing

- 1,038,971 free throws (shootouts).

The stick is used in the game as follows. Stopping the puck, driving it along the site, throwing or transferring are carried out by the lateral surfaces of the elastic plate 3 of the hook 2. When the puck is stopped flying at high speed, the plate is deformed and bending within the elasticity set for it smoothly dampens the speed of the washer, which excludes the possibility of its rebound from the hook , i.e. increases the efficiency of stopping the puck with either side of the hook.

During transfers or throws at the moment of contact of the puck with the plate, the latter bends within the limits of the elasticity set for it, which gives the puck an additional impulse of energy, leading to an increase in the throwing force and, accordingly, the puck's flight speed.

In the process of dribbling the puck around the court, the player, stopping the puck with the side surface of the hook plate, can, by moving the hook of the stick over the puck, instantly perform a strong throw or transfer the puck in the direction of its movement with the opposite side surface of the hook, while being in any position anywhere on the playing court ... The execution of a hook with a flexible elastic plate between the branches of the bracket allows, regardless of the functions of the players (right, left, center, goalkeepers, free throws), to use during the game the advantages of the concave sections of the plate formed on the lateral surfaces of the hook during the throws and transfers of the puck. The formation of concave sections on both sides of the club hook plate during contact with the puck makes it possible to improve the convenience of handling it at various points of the playing court while significantly simplifying the design and increasing reliability, while reducing the time for transferring and throwing the puck, which, in turn, will lead to increasing the effectiveness and entertainment of the game due to increased strength and accuracy of shots, effective stopping of the puck and the use of the factor of surprise of shots and passes for opponents. The use in the proposed technical solution of new materials and elements, their shape, mutual arrangement and their interconnections will make it possible to achieve the assigned tasks characteristic of the object as a whole, and not for its individual elements. The proposed solution can be used in the production of both children and youth, as well as mass and master clubs for players of all ages.
