RU228320U1 - Sound mechanical hockey puck for the blind and visually impaired - Google Patents

Abstract

The utility model relates to sports equipment, in particular to ice hockey pucks for blind and visually impaired athletes. The puck is made in the form of a disk (1) made of elastic low-elastic material (rubber or fluoroplastic), having increased overall dimensions of a hockey puck (a cylinder with a diameter of 14 cm and a height of 4.8 cm). A hollow cylindrical case (2) made of metal and placed on the axis of symmetry of the elastic cylinder is mounted in the elastic cylinder. The dimensions of the case in height correspond to the size of the elastic cylinder (4.8 cm), in diameter 1.0-1.5 cm smaller than the elastic disk. Inside the hollow case there are metal balls (3), the size of the metal balls from 0.2 cm to 1.5 cm, or bells in the form of spherical bells. The bells are 1.5 to 2 cm in size and are hollow metal balls (4) containing 5 to 10 solid metal balls 0.1 to 0.3 cm in size inside. The technical result that the utility model is aimed at is a sound effect: when the puck moves during acceleration, the metal balls or bells placed in the cavity of the metal case produce rattling sounds that occur when the balls collide with the metal surface of the hollow cylindrical case and allow players to determine the location of the puck by sound signals.

Description

The utility model relates to a sports product, in particular to training hockey pucks, designed to improve the quality of the game process of blind and visually impaired ice hockey players.

There are various modifications of the puck for classic ice hockey, intended for healthy sighted athletes and aimed at improving the qualitative characteristics and quantitative indicators of players during the training and game process. Known are a training hockey puck (SU 1378871) containing a mechanical means for changing the trajectory of the puck, located in the cavity of the housing, a hockey puck (SU 1710085) containing one of the bases made in a convex shape, a hockey puck with a beveled base (RU 167768), a hockey puck with a built-in mass compensator (RU 2031678), a hockey puck-trainer for training dribbling on "non-ice" surfaces (RU 2623669), a hockey puck, characterized in that it includes a cylindrical disk, which has a central core made of hard rubber and an annular shock absorber made of softer rubber or similar material, completely surrounding the periphery of the hard core to reduce the force of impact when the puck hits a player during a game (RU 96108825) a training puck and a sticker for practicing direct shots on goal from the support points and lines of the hockey rink (RU 97645)

For blind players, there are inventions that provide for a specialized design of the playing field for sports, for example, a field for blind football players (RU 69757), or the presence of specialized devices for detecting objects: a visual and sound system for blind and visually impaired people (RU 2679866 C1), a sound device for an information stand for the blind and visually impaired (RU 171873). All these inventions require complex electromechanical or electronic structures and cannot be used for playing ice hockey without building special structures.

There are no structural analogues of a sound washer for blind athletes based on the sound-mechanical noise effect.

The essence of the utility model is explained by drawings,

where Fig. 1-4 shows variants of the hockey puck design.

The puck is made in the form of a disk (1) made of an elastic, low-elastic material (rubber or fluoroplastic) with increased overall dimensions of a hockey puck (a cylinder with a diameter of 14 cm and a height of 4.8 cm). A hollow cylindrical case (2) made of metal and placed on the axis of symmetry of the elastic cylinder is mounted in the elastic cylinder. The case can be made of any hard metal, the thickness of which allows it to remain intact when colliding with a stick, gates and sides of a hockey field. It is advisable to use stainless steel with a thickness of at least 1 mm. The dimensions of the case in height correspond to the size of the elastic cylinder (4.8 cm), in diameter 1-1.5 cm smaller than the elastic disk. The case is attached to the rubber cylinder mechanically due to the elastic forces of the rubber cylinder with the possible additional use of high-strength glue. Metal balls (3) are placed inside the hollow metal case. The size of the metal balls is from 0.2 cm to 1.5 cm. Or bells in the form of spherical bells. The bells are from 1.5 to 2 cm in size, they are hollow metal balls (4), inside of which there are from 5 to 10 solid metal balls measuring from 0.1 to 0.3 cm.

In addition, it is possible to use a solid metal puck design. In this case, the dimensions of the cylindrical case will correspond to the dimensions of the puck, and the rubber cylinder will be absent. With this option, the sound characteristics of the puck increase due to the absence of a rubber layer, which prevents the complete transmission of the sound signal from the balls inside the case, as well as a wider area of the round ends of the case, creating a drum sound effect, which is a plus for blind and visually impaired players, but the safety characteristics for players are reduced, since the metal cylinder has a more rigid structure.

Fig. 1 schematically shows a variant of the washer from above,

where 1 is a rubber cylinder, 2 is a metal case, 3 are balls or bells inside the metal case;

Fig. 2 shows a version of the washer - side view (same designations);

Fig. 3 shows a drawing of a bell that can be used to obtain a stronger sound effect.

The bell is a hollow sphere - 4 made of metal, inside of which are solid metal balls - 3. When the washer moves, the bells roll inside the metal case and the balls inside the bells create an additional sound effect;

Fig. 4 shows the design of a washer without a rubber shell

The technical result achieved by the utility model is an increase in the efficiency of the game process when playing hockey by visually impaired and blind athletes due to mechanical sound (noise) signals coming from a moving puck during the game of ice hockey. Blind and visually impaired athletes will receive an additional source of orientation in the form of noise emanating from the movement of balls or bells inside a metal case, caused by changes in the trajectory of movement and speed characteristics of the puck.
