Abstract

The invention relates to a mechanical device for high-impact training, which provides constant reference points for racket sports that use a ball that can be hit in various ways, and require technical capacities for the handling of the racket during the three-dimensional impact, in addition to the necessary body control, hitting force, directionality and effect during the movement. In this way, the equipment enables an effective training from the basic elements to the technical improvement of each type of hit according to the demands of the technique to be practised, owing to the fact that it provides a real sensation of the ball in play, and also maintains predetermined reference points for the user or trainer, as they can three-dimensionally adjust (different angles or planes), as they wish, the orientation of the rotational axis of the contact point, and the variables of direction, height and direction of rotation or turns desired at said point. Furthermore, at least one impact poi nt can exist simultaneously.

Description

THREE-DIMENSIONAL MULTI-ANGLE ROTATIONAL GUIDE Object of the Invention Mechanical equipment for high impact training with constant reference point for racket and ball sports, is the invention of a three-dimensional multiangular rotational device, which is composed of: a joint screw, a guide positioner, a subject ball rotational simulator by a clamping screw for the free rotation of the simulator and a racquet inclination guide, in order to obtain numerous and notable advantages over other existing devices.

BACKGROUND OF THE INVENTION To date there are several devices for training in sports such as table tennis and field tennis. These teams can be classified into two large groups. The first one would refer to those equipment that throw balls to a player who is in a position to play and who must respond to the sending of the ball. The second one would refer to the teams that have an attachment that simulates a ball and that is hit repeatedly in order to improve the technical mastery in the handling of the racket. While both types of equipment allow the player to improve their performance during the game, so is the fact that they lack elements to achieve technical mastery in the basic and advanced player, that is, the technical learning of the various strokes that characterize these sports is inefficient. The first group of teams is based on the launching of a ball in real time, which prevents the coach and player from structuring the desired hit efficiently, an aspect that is only achieved after constant and long-term repetition, coupled with the cost of these robots and / or guns throw balls and the excessive number of balls that require, increases the necessary investment considerably. i While the latter, are based on the possibility of having a reference point that simulates a fixed ball, which in the best of cases, only rotates vertically and allow to dominate certain areas in the handling of the racket, but by not being able to rotate it in different directions (horizontal, vertical or diagonal), or to be able to locate this direction in a three-dimensional way or in several angles or planes for contact and ball effect, the training is limited and is of little use To improve the level of competition, even when its costs are lower than those of the robots, it throws balls, the benefit obtained with these equipments is limited and at the end it gives few competitive advantages in the short term, to the player who uses it in his training (US Patent, 4 417 730, 1983).

In order to favor an efficient training of the punches in basic level players and at the same time offer the possibility to coaches and advanced players, the present team was developed, a tool that offers a constant and controlled reference point through the adjustable three-dimensional modification of the orientation of the rotational axis (turning the simulated ball), which has the possibility of simulating the effect of the ball during the impact, also allows to improve the domain of the racket in such a way that each stroke can be practiced with the degree of inclination that must take the face of the racket to the entrance and exit of the response movement, this allows the player and the coach to prepare the shots from their basic position and up to the achievement of technical mastery in terms of body position, muscle tone necessary at the moment of the blow or impact ("the touch") and the dominance of the ball in the direction, angles and planes (sense trid imensional) and the direction of rotation, effects or desired turns.

TECHNICAL DESCRIPTION The three-dimensional multiangular rotational guide al you to locate the point of contact (simulator disk or real ball) at any desired degree of the three axes or planes (x, y, z), that is, it can be moved and adjusted in a three-dimensional way. This makes it possible to practice b with different angles, planes and directions. It gives the user a better option of realism to their training. This guide consists of: (1) Union screw: in addition to its function of attachment to the arm, it is used to adjust the depth of the impact point with respect to other points located transversely on a unidirectional arm. (2) guide positioner: element by which the angle of the guide is adjusted in 360 ° of rotation with respect to the axis of the unidirectional arm and up to 180 ° in relation to the angle of the point of impact, which gives the three-dimensionality to the simulation of the coup. . (3) Rotational ball simulator with disc or real ball, it is noted that the rotation of This element is free and continuous on a single axis, (4) Racket inclination guide, al to identify the entry and exit orientation of the face of the racket. (5) Thimble of the rotational axis of the ball simulator. It supports the ball simulator and al it to rotate as freely as possible when passing through its central part from side to side.

The general base (figure 2), (portable or fixed), is a support of the equipment, which will have the function of holding it with the minimum of oscillatory or negative balancing movements and alng the free operation of the high impact reference point constant, you have the option of a Mini Base for Table Tennis. This general base consists of (6) Extension bar with vertical adjustment and 360 ° rotation in the horizontal plane (removable and interchangeable), includes a multiplane support head for unidirectional arms that al the placement of one to three of these arms in vertical, horizontal or diagonal positions; (7) Tripié (folding), (8) Segmented stabilization ring (removable) (9) Mini table tennis base (optional).

For its part, the Unidirectional Arm (figure 3) is an important element of the team. Bar that al the movement of round trip in a single plane, movement that is given thanks to the Guide of Transit and whose advance and backward movement is regulated by Springs and Resistance Elastic Bands. Its function is to support the rotational guides, al the placement of points of impact at various distances on the same arm. Said arm consists of (10) an arm, (1 1) a Transit Guide, al movement of the arm at angles of up to 90 °, (12) Springs and elastic resistance bands, and (13) a multiplane arm support unidirectional, al the placement of each arm in vertical, horizontal or diagonal position.

The plate used (14) for adjusting the position of a unidirectional arm al the use of three arms simultaneously in the equipment; two in horizontal position (right and reverse) and one placed in vertical position (90 °) or any of them at angles between 35 ° and 45 °, for the training of high b.

The Constant High Impact Reference Point is a portable or fixed mechanical device that, in conjunction with this new device, the Three-dimensional Multiangular Rotational Guide is designed for the effective training of racket and ball beating from stable reference points, for its constant and controlled repetition, without requiring electric power and without using a single ball for its operation; with the aim of promoting the improvement of the technique of beating of racket sports, such as: Table tennis, Tennis, Squash, Racquetball or Padle Tennis. It will also allow the possibility of pointing; using the equipment as a reference and with a better didactic, endless indications prior to the realization of a single stroke or technique to teach, such as: the correct position of the type of "grip" of the hand of the student with his racket for a certain type of stroke that one wishes to achieve, or the improvement of the "touch" (degree of sensitivity of the tone or muscular force necessary for the impact) and, the application of techniques of "stopped" or the so-called "Ready Position" for an embodiment of attack, or reception of balls as well as general movements (biomechanics) of preparation, point of contact with the ball and the termination of the type of stroke to train jointly, in addition to achieving a better overall coordination of the body during the same, etc., among many other indications and / or instructions.

By means of the equipment, one can simulate exactly the actual hitting of a ball with a racket, from a low to medium intensity hit and / or to the high impact if it is required, immediately obtaining the return of it to the original point of impact or reference to practice, being able to regulate the speed of return with greater precision later, to then initiate another blow, in an unlimited way, with the objective of perfecting it.

The feeling of reality of this hit is achieved before the possibility of printing the "effect" or turns to the point of reference, as occurs with a ball in real game, by controlling the variables of direction, three-dimensional angulation at the point of impact, height, and distance between points of contact, especially when placing devices made for this purpose, such as the rotational guides with disc or rotational guides with ball Real.

Considering the Practice or the Teaching of beating with a racket to a ball directed to a player of initiation, intermediate or advanced, in any of the sports before mentioned implies; A well-defined reference point, as well as a pre-established "grip" of the racquet, that is, the inclination of the face of the racket that it must have in the three moments that characterize a certain stroke (preparation, contact point) and ending or closing) and a "stopped" position, specified prior to the performance of the practice or of certain movements of "attack" or "defense" towards a ball, and in addition to a certain height and distance in which will hit that point, the following adjustments will be made to the equipment: By means of the extension bar, Fig. 2, (6) the height of the unidirectional arm Fig. 1 (10) is positioned to obtain the height to be practiced of the ball (from a low ball, to hits at the height of the shoulders of an average adult, 1.75 m) or adjust the necessary height to the Mini Table Tennis Base, Fig. 2 (9). It should be mentioned that being a prototype only currently has the capacity to adjust the equipment to certain heights temporarily, since with a special support it will be possible to place the reference point of constant high impact on the ceiling at an "X" height and perform much higher blows such as the so-called "serves" or "services" especially in field tennis.

The three-dimensional multiangular rotational guide will be adjusted according to the planes of the direction of rotation, Fig. 1, which is required, which gives a three-dimensional effect when achieving both the rotation of the guide, Fig. 1 (3), and the necessary angle (s), to simulate the point of contact, either individually on the Guide Positioner, Fig. 1 (2), or in conjunction with several rotational guides on the same arm, Fig. 4 (as required for different cases or techniques.

The unidirectional arm, Fig. 3 (10), will act according to the blow made, and because of the operation of the resistance springs, Fig. 3 (12) the unidirectional arm, Fig. 3 (10) and the guide transit, Fig. 3 (11) will return the reference to the same initial point for the repetition of the same movement or hit in question, with the objective of perfecting it; thus obtaining the sensation of the real blow and the effect to be applied It gives the coach the possibility to explain in detail the technical differences that need to be known before being able to perform real movements in a court of official characteristics and even to be able to take the team to the real game area because it has the distinction of being a portable equipment or to fix it definitively to the floor if it is required.
