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 point can exist simultaneously.

Description

THREE-DIMENSIONAL MULTIANGULAR ROTATIONAL GUIDE

Object of the Invention

Mechanical equipment for high impact training with a constant reference point for racket and ball sports, is the invention of a three-dimensional multiangular rotational device, which is composed of: a connecting screw, a guide positioner, a rotational simulator of subject ball by a clamping screw for free rotation of the simulator and a racket tilt guide, in order to obtain numerous and remarkable advantages over other existing devices.

BACKGROUND OF THE INVENTION

To date there are various devices for training in sports such as table tennis and field tennis. These teams can be classified into two large groups. The first of them would refer to those equipment that throws balls at a player who is in the game position and who must respond to the sending of the ball. The second would refer to the teams that have an attachment that simulates a ball and is repeatedly beaten 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 a technical mastery in the basic and advanced player, that is, the technical learning of the various strokes that characterize To these sports is inefficient. The first group of teams is based on the launch of a ball in real time, which prevents the coach and player from efficient structuring of the desired blow, an aspect that is only achieved after the constant and long-term repetition, coupled with this, the cost of these robots

and / or cannons throws balls and the excessive number of balls they require increases the necessary investment considerably. While the latter, are based on the possibility of having a reference point that simulates a fixed ball, which in the best case, rotates vertically only and that allows certain areas to be mastered in the handling of the racket, but Being unable to rotate it in different directions (horizontal, vertical or diagonal), nor being able to locate this direction in a three-dimensional manner, that is, at various angles or planes for contact and ball effect, training is limited and is of little use To improve the level of competition, even if their costs are lower than those of the robots throwing balls, the benefit obtained with these teams is limited and gives in the end few competitive advantages in the short term, to the player who uses it in their training (US Patent, 4 417 730, 1983).

In order to favor an efficient training of the blows in players of basic level and at the same time offer the possibility to coaches and advanced players, the present equipment 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 (simulated ball rotation), which has the possibility to simulate the effect of the ball during the impact, also allows to improve the domain of the racket so that each stroke can be practiced with the degree of inclination that the face of the racket should take to the entrance and exit of the response movement, this allows the player and coach to prepare the blows from their basic position and until the achievement of technical mastery in terms of body position, the necessary muscle tone at the time of the blow or impact ("the touch") and the mastery of the ball in the direction, angles and planes (three-dimensional direction) and the direction of rotation, effects or desired turns.

The three-dimensional multiangular rotational guide allows 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 three-dimensionally. This allows the practice of blows with different angles, planes and directions. It gives the user a better realism option to their training. This guide consists of: (1) Connecting screw: in addition to its arm fixing function, it is used to adjust the depth of the point of impact 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 blow. . (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, allows to identify the input and output orientation of the Racket face. (5) Ball screw simulator rotational axis clamping screw. It supports the ball simulator and allows it to rotate as freely as possible as it passes 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 supporting it with the minimum of oscillatory or negative rocking movements and allowing the free operation of the high impact reference point. constant, you have the option of a Mini Base for Table Tennis. Said general base consists of (6) Extension bar with vertical adjustment and 360 ° rotation in the horizontal plane (removable and interchangeable), includes a multi-level support head for unidirectional arms that allows the placement of one to three of these arms in vertical, horizontal or diagonal positions; (7) Tripod (folding), (8) Segmented stabilization ring (detachable) (9) Mini table tennis base (optional).

The Unidirectional Arm (figure 3) is an important element of the team. Bar that allows the round trip movement in a single plane, movement that is given thanks to the Transit Guide and whose advance and recoil is regulated by Springs and Elastic Resistance Bands. Its function is to support the rotational guides, allows the placement of impact points at different distances on the same arm. Said arm consists of (10) an arm, (11) a Transit Guide, allows movement of the arm at angles of up to 90 °, (12) Springs and elastic resistance bands, and (13) a multi-plane support of the unidirectional arm , allows the placement of each arm in a vertical, horizontal or diagonal position.

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

The Constant High Impact Reference Point is a mechanical equipment portable or fixed that together with this new device, the Three-Dimensional Multiangular Rotational Guide is designed for effective racket and ball hitting training from stable reference points, for constant and controlled repetition, without requiring electrical power and without use a single ball for its operation; with the aim of promoting the improvement of the technique of hitting racket sports, such as: Table Tennis, Tennis, Squash, Frontenis or Padle Tennis. It will also allow the possibility of pointing; using the equipment as a reference and with a better didactic, an endless number of indications prior to performing a single stroke or technique to be taught, such as: the correct position of the type of "grip" of the student's hand with his racket for a certain type of blow that is desired to be achieved, or the improvement of the "touch" (degree of sensitivity of the tone or muscular force necessary for the impact) and, the application of "stopped" techniques or the so-called "Ready Position" to an accomplishment of attack, or reception of balls as well as of general movements (biomechanics) of preparation, point of contact with the ball and the termination of the type of hit to train together, in addition to achieving a better total coordination of the body during the same, etc., among many other indications and / or instructions.

Using the equipment, you can simulate exactly the actual hit of a ball with a racket, from a low to medium intensity hit and / or to the high impact if required, immediately obtaining the return of the ball to the original point of impact or reference to practice, being able to regulate the speed of return with greater precision later, to then start another stroke, unlimitedly, in order to perfect it.

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

Considering the Practice or Teaching of hitting a ball with a racket to a player of initiation, intermediate or advanced, in any of the aforementioned sports implies; A well-defined point of reference, as well as a "grip" of the racket already preset, that is, the inclination of the face of the racket that must have in the three moments that characterize a particular hit (preparation, contact point and termination or closure) 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 at which will hit that point, the following adjustments will be made to the team:

Using the extension bar, Fig. 2, (6) the height of the unidirectional arm Fig. 1 (10) is positioned to obtain the height to practice of the ball (from a low ball, until blows 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 is worth mentioning that being a prototype currently only has the capacity to adjust the equipment to certain heights temporarily, since with a special support the constant high impact reference point can be placed on the ceiling at a height "X" and may be Perform much higher blows such as the so-called "serves" or "services" especially in the Field Tennis.

The three-dimensional multiangular rotational guide will be adjusted according to the direction or planes of the direction of rotation, Fig. 1, which is required, which gives a three-dimensional effect by achieving both the Rotation of the guide, Fig. 1 (3), as the angle (s) needed to simulate the contact point, 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 due to the operation of the resistance spring (s), Fig. 3 (12) the unidirectional arm, Fig. 3 (10) and the guide transit, Fig. 3 (1) will return the reference to the same starting point for the repetition of the same movement or hit in question, with the aim of perfecting it; thus obtaining the sensation of the real blow and the effect to be applied

It gives the coach the opportunity to explain in detail the technical differences that need to be known before being able to make real movements on a court official characteristics and even to be able to take the equipment to the real play area because it has the particularity of being a portable equipment or of fixing it definitively to the floor if required.
