Description

Title of the invention: Device for playing with balls

[0001] The invention relates to the sphere of sport, games and entertainment, namely the construction and shape of a device for playing with balls.

[0002] Games have served people for many years as a good distraction, a means of improving various skills or improving physical health, including games with one or more balls, which at a certain time in the game, in order to perform the task of a particular game, must roll on the surface of the game board before stopping the ball in a preferred position on the game board, or to hit a target with the ball or perform another task provided for by the rules of a particular game.

[0003] Some of these games are individual, some involve the participation of several players or teams. But nowadays, in the context of the rapid development of video games and online entertainment, it is difficult to overstate the importance and social benefits of these games, which provide a means of live communication and interaction between people.

[0004] At the same time, the prevalence of games involving direct contact between players and their accessibility, including in public places, are influenced not only by how interesting and popular they are, but also by how much space is needed to play such games. This, in the context of the high cost of land and real estate, especially in large cities, makes games that do not require much space more preferable.

[0005] For example, games like bocce or pétanque have a very good set of qualities and are very popular in many countries. They are interesting, their rules are not complicated, they do not involve significant physical exertion, they do not require any special skills or extensive experience, and they are perfect for different ages and communication styles. But the fact that they require a significant amount of space to play considerably reduces the number of places available for them.

[0006] One possible solution for increasing the accessibility of games, including in public places, could be to reduce the size of the devices or play areas, but the difficulty encountered in such attempts lies in the need to find a balance between numerous factors that influence how interesting and popular a given game will be. And it is extremely difficult to determine in advance the degree of influence of a particular factor.

[0007] For example, by analyzing the possible reasons for the not very high popularity of reduced versions of billiards, it can be concluded that the degree of reduction in length The distance a ball can travel on the playing surface before its first ricochet or before it falls into the pocket can also be important to keep the game interesting, and it would be rational to consider this in attempts to reduce the dimensions of devices for playing with balls.

[0008] Thus, from the prior art, a device for playing miniature pétanque is known, consisting of a rectangular table which is a longitudinal playing surface, supported by legs (see patent EP 0 320 427 A2, class A63F 7 / 06, A63F 7 / 00, published 14.06.1989). This device, compared to classic pétanque, although it suggests the possibility of reducing the length of the space required for playing, has the same imperfection as miniature billiard tables.

[0009] The imperfection of this known playing device is that the maximum length of the path that a ball, with a single acceleration, can overcome within the limits of the device for playing with balls, without any ricochet of the ball on the playing board of this device, is strongly dependent on the length of this device, which makes the game less interesting on the device with a reduced length.

[0010] The objective of the invention is to eliminate this said imperfection and to increase the arsenal of devices for playing with balls, with a reduced length.

[0011] The technical result consists of increasing the maximum length of the path that a ball, with a single acceleration, can overcome within the limits of the device for playing with balls, with a reduced length, without any ricochet of the ball on the playing surface of this device, by making a device for playing with balls, containing, in addition to the playing surface, a starting platform, which serves as an additional surface for the movement of the ball, and equipped with at least one accessory to redirect the ball from the starting platform to the playing surface of this device.

[0012] The problem is solved and the technical result is obtained by the fact that the proposed device for playing with balls contains a set of balls and a game board that remains stationary during the game, representing a surface on which, due to the movement of the balls, a task provided for by the rules of a particular game can be carried out. At the same time, in addition to the game board, the device contains a starting platform, representing an additional surface for the movement of the ball, and is also equipped with at least one accessory for redirecting the moving ball from the starting platform to the game board. At the same time, the starting platform is surrounded by a barrier, which defines the outer limit of that part of the surface of the starting platform with which the ball can come into contact when moving on the starting platform, and the shape of this outer limit is a closed and smooth convex curve without corners.At the same time, the accessory for redirecting the moving ball from the starting platform to the playing surface contains at least a portion of the surface with a concave shape, which is intended to come into contact, with the ball, and perform the role of guiding surface for a smooth movement of the ball from its movement trajectory along the barrier of the starting board to the initial movement trajectory on the playing board.

[0013] The proposed device for playing with balls can be made in the form of a table device, but the proposed device can be made with its own support devices of a height greater than 50 centimeters, which allow the device to stand on the ground independently of other objects and to be at the height of these support devices.
