FR3036291A1 - TARGET ON THE GROUND TO MEASURE AND ANALYZE THE PRECISION AND REGULARITY OF A TENNIS BALL JET - Google Patents

Abstract

The invention relates to an electronic device for measuring and analyzing, thanks to targets placed on the ground, the precision and regularity of the throws of a player's ball, particularly tennis. The device concerns Plexiglas targets of small thickness (3 cm) placed on the floor and forming a target area of variable size. The device consists of a target zone composed of a mother target, to which can be added up to 8 girls targets, connected to a screen for viewing the impact results on the targets. The target girls (70x70cm) are assembled to the mother target (70x70cm) and to each other to create a target area of 210 x 210 cm maximum. The player will aim at the target and each bullet impact is measured independently by each target.

Description

The present invention relates to the field of sport and more specifically to tennis or other sports. It is a system allowing a player to train while receiving information on the accuracy and regularity of his shots. The invention relates to a device for disposing of the ground targets that the player will aim during his exchanges and which will transmit the results to a screen placed near the player through a data processing software. The state of the art: The state of the art is composed of target devices for tennis players or other sports but these devices consist essentially of vertical targets, which poses the problem of their installation , their stability and lack of precision, the essential for a player is to know where his ball will touch the ground. Thus, for example, French Patent No. 1302032 relates to a training target system for analyzing the impact of a ball based on the principle of a vertical target, placed on a frame.

The international patent WO2013005064 relates to an electronic system measuring the regularity of an archer, the target is in this case placed vertically on a carriage that can be moved. EP 0890075 B1 discloses a method for deciding, with respect to a selected reference system, and without contact, the position, the direction or the speed - or any combination thereof - of a projectile in its flight through a gas in a direction towards a given target. US 5924867 A discloses a system for measuring trajectory and regularity for an arc shooter filmed by several cameras at the firing point, along the trajectory and at the target.

The patent W008706848 relates to a training device characterized in that the tennis student must play against certain target objects or in target areas, if the object is struck, an acoustic or visual signal is emitted. This device is also based on vertical targets that the player must aim. Disadvantages of the Prior Art 3036291 2 The different inventions constituting the prior art have vertical targets requiring a heavy system of maintenance and implementation. The different inventions constituting the prior art do not make it possible to vary the size of the target. Solution Provided by the Invention The device according to the invention makes it possible to remedy these drawbacks by making it possible to dispose flat targets (3 cm thick and 2 kg per target) on the ground at the place chosen by the player and to move them easily. The variable size of the target area makes it possible to adapt the use of the device. The independent character of each target area target allows for differential target settings and more accurate results analysis.

DETAILED DESCRIPTION The device according to the invention is an electronic system for collecting and analyzing specific data, in the field of sport, especially tennis but also volleyball, badminton or others. The device according to the invention is composed of three elements: A target zone lying flat on the ground making it possible to define the projectile drop zones composed of 8 independent daughter targets connected to a mother target; - A display screen of the results; - A data processing software for setting the target area and each of the target girls; The target area is of variable size, it is composed of nine elements of 70 x 70 cm, assembled, so that the target area reaches a maximum dimension of 210x210 cm. There is a so-called "mother" target placed in a corner of the target zone, and 8 "girls" targets forming the target zone (FIG. Each target girl, and the mother target, is independently configurable. Targets individually gather information at each impact. It is possible to program the reaction of each of the components of the target zone in a different way (example: 1 point if we touch the daughter target A, 2 points for the daughter target B, 3 points for the daughter target C, etc.) . This information is transmitted to a software and displayed on the screen. The target girls in the target area are made of Plexiglas and are resistant to impacts and all types of weather. They are able to react when they are impacted. This reaction can be validated by different signals (sound, visual, points).

3036291 The software receives information about each target. Thanks to this information it is possible to define different data, such as statistics (example: percentage of success according to the target girl affected), rankings (between different users), etc. It is also possible to manually add information such as discipline, participant's name, result, ranking, etc. This software is connected to a screen that displays the contents of the software. The screen is mobile, resistant and suitable for outdoor conditions. It displays the information about the targets. All elements of this device communicate via electrical cables. An evolution of this system will allow the removal of the cables through the establishment of wireless communication. Another evolution of this device will allow the software to communicate with a bullet gun. Another development will connect several target areas to the system so as to cover a larger area of land. Figure 1 shows how the system is installed in the field.
