DESCRIPTION

Improvements in training system in ball sports.

Technical sector

The present invention falls within the field of sports training, more precisely the training of the handling of the ball, ball, disc or other object that players must handle on the pitch.

Explanation of the invention.

The present invention relates to improvements introduced in the subject of patent applications No. P201600526 and No. P201601020, relating to a system for training in ball sports. These requests are based on presenting a stimulus to a user who is driving a ball to cause behaviors that facilitate their learning.

The main difference between this invention and the main requests is that different means are used to provide dynamic stimulation to the user while the user is running on a field, for example a training ground (i.e., not running on a tape apparatus of running). In this context, presenting the stimulus dynamically means that it is an element that is moving in front of an element that could be static as the user approaches it.

In the main application no. P201601020 an embodiment for carrying out such an invention is already described. The state of the art in this aspect is represented by a training technique in which the user drives a ball in a zigzag path by drawing some cones. This is a solution that uses static means, such as cones. An inventive solution described in said main application No. P201601020 is to arrange a structure along a length in a training field, such that said structure has one or more elements that move longitudinally along said structure for Create a stimulus to the user. In some cases, for a given longitudinal position, the elements may also move longitudinally and / or transversely in the environment of said position. That is, these moving elements are presented to the user in a dynamic way and require the user to make a decision on the fly about how to perform an evasion movement, and must calculate the movement of said elements, in addition to simply performing that movement. because it approaches a cone that by this static demands a lower user skill.

In this application, this line is continued and the other means described in the main applications No. P201600526 and No. P201601020 are used for the user to carry out his training while handling a ball on a field, instead of doing so in a treadmill apparatus. The advantage of the terrain on the treadmill is that it allows the user to train in handling the ball with the same biomechanics that he will then use on the playing field. In this request, the user may be advancing or standing while driving the ball and certain elements will cause him a stimulus to affect his behavior.

In the case that the user is running, the biomechanics of running on a tape apparatus is usually different from that of running on a terrain. When running on the ground, the main effort occurs when pushing with the foot on the ground and bringing the weight of the body forward. In contrast, in a treadmill, the user usually adopts a different technique. If the belt apparatus is motorized, the belt brings the foot back without the body moving and the main effort occurs when picking up the foot from the back and carrying it forward. It may happen that running on a motorized belt requires less effort than running on a terrain. For example, it has been found that the energy consumption running on a motorized treadmill is less than running on a terrain. Specifically, it was found that the oxygen deficit after sprinting over a comparable distance was 30% greater if it was run on the ground (Frishberg, BA (1982). An analysis of overground and treadmill sprinting. Medicine and Science in Sports and Exercise, 15 (6), 478-485). When running on a treadmill, the person can perform a greater number of steps per minute, but with less force. If the tape apparatus is not motorized, the situation is more complex, because it usually requires the user to push handrails or another site (Luchtenstein, L., Barabas, J., Woods, RL, & Peli, E. (2007) A feedback-controlled interface for treadmill locomotion in virtual environments ACM Transactions on Applied Perception (TAP), 4 (1), 7). The most modern non-motorized belt devices usually have a curved surface in the front that allows the user to run with more power without leaving the belt.

However, it should be emphasized that running on a motorized belt apparatus has other advantages for the user over training in the field, and therefore both approaches are complementary. Because of this, some of the embodiments of the present application are also directed to a treadmill-based training system.

Due to the fact that the person can perform a greater number of steps per minute on a tape device, he is forced to control the ball more times and at a faster speed. In addition, the tape apparatus makes it easier to control the training because it can be applied over an unlimited time and in a homogeneous way because the person is in the same position. It may also be easier to perform the necessary installation to perform the functionalities of the main applications on a treadmill device than on a device that is on the ground. And it is also easier for a person who is supervising the training because it is close to the person performing the training. It also imposes a pressure on the user, who is obliged to maintain a certain speed. The training supervisor may gradually increase the speed of the tape, and the user will experience a gradual pressure to adapt to the tape and therefore on his ability to control the ball. This will be different from the pressure you may feel on a terrain when you are forced to run faster.

The variants of the present application related to tape apparatus refer to a training system in which a user drops a basketball while running on a treadmill. Due to the difficulty of creating a treadmill that absorbs the impact of a basketball with sufficient rigidity, the user bounces the ball in a static area to the treadmill but very close to it. There is an ice hockey training system in which a user skates on a treadmill while controlling a disc (https://youtu.be/ig3k00AFox0?t=103), but we don't know anything applied to basketball. Nor do we know anything in which the user is doing a cognitive activity and must perform movements that respond to the stimuli that appear on that tape. In a particular variant of this invention, there are means for generating a stream of air that moves said balloon slightly when bouncing in said external static zone. This serves to simulate the slowdown suffered by a ball when a player runs bouncing a ball at a time when the user is not in contact with the ball.

DISCLOSURE OF AN EMBODIMENT OF THE INVENTION

To introduce the explanation into context, Figure 1 (which is brought from the main application No. P210601020) shows a usual way in the state of the art to train the ball control in motion. A person 101 moves along a terrain 102 following a direction 103 while driving a ball 104, and advances for example from a point 105 to a point 106 and has to circumvent cones 107. The path marked in Figure 1 merely has the function of illustrate the exercise, as there will usually be no path marked or marked as such. Likewise, points 105 and 106 do not have to be marked, and simply point out the fact that the user begins the exercise and ends it in another. Figure 2 (also brought from main application No. P201601020) shows an embodiment of the invention described in said application for carrying out said training which has advantages over the state of the art. Figure 2 shows some lines indicating the path of 102 which, as in Figure 1, is merely illustrative, and does not necessarily have to exist. User 101 moves between points 105 and 106 (which also do not have to be marked), which are separated by a distance that can be chosen at will, and on its way it has to overcome obstacles 201. Two instances of obstacle 201, 201a and 201b, are shown. In this document, when there are several instances of an element type, the same numerical indicator will usually be used for them and they are differentiated by an alphabetic suffix). The obstacles 201 can be moved in any direction, and it is observed that the obstacle 201a comes from the path 202 and is advancing on the path 203. The obstacle 201b comes from the path 204 and is advancing on the path 205 towards the user, which is performing an evasion move by taking the ball to your right. Obstacles 201 can be moved in any direction thanks to the fact that they are held by moving joints 206, which are connected to elements 207, which are subject to a mobile joint 208 that connects them to a bar 209, which can move to along a long bar 210 along the path that the user 101 will follow. The bar 209 moves in the direction 211. Cameras 212 and 213 (of which there may be more than two depending on the design and the embodiment) serve to identify the position of the user 101 and, depending on the embodiment, of the ball 104. The whole process is coordinated by the computer 214, which moves the obstacles 201a and 201b (and for this also moves the bar 209 and the appropriate elements when it is necessary) along the appropriate trajectories to cause a stimulus in the user 101 and cause behaviors that help their training.

This embodiment can also be used in a way in which the user is handling a ball without moving, for example throwing the basketball, and it is the obstacles 201 that come towards the user and he has to evade them. Obstacles 201 may come from one direction or from several different directions.

In the present invention, in one embodiment, shown in Figure 3A, there are long railings 301a and 301b, of 50 meters, which extend over the same length in the training field where the user will advance. In these railings 301 there are two supports 302a and 302b with mechanical arms 303a and 303b that can move through said railings. The supports 302a and 302b also have built-in dolls 304a and 304b to add some realism to the practice and facilitate the user to better perceive the position of the mechanical arms 303a and 303b. Cameras 212 and 213 (the number of cameras depends on the design) film the scene and detect the position of the ball and the user. The computer 214 controls the speed at which the supports 302 of the mechanical arms 303 move, which move independently along the paths 305 and 306. In this embodiment, as the computer 214 moves the supports 302 that support the mechanical arms 303 , knows where the supports 302 are at all times. As described in the main applications, when the ball reaches too close to one of the mechanical arms 303, the computer 214 shoots the corresponding arm 303 and intercepts the ball 104.

This embodiment, and the others described in this application, can be used in a large plurality of ways. In one way, the supports of the mechanical arms advance at a constant speed over the railings and the user must follow them as close as possible preventing the balloon 104 from getting too close to the mechanical arms 303. In another way, the supports 302 will advance always keeping a certain distance from the user, and the user must move as fast as possible to finish the journey in the shortest possible time. In another way, the supports 302 advance irregularly, sometimes more slowly and sometimes faster, and the user must finish the journey as quickly as possible, always preventing the arms 303 from firing and impacting on the ball 104. These Ways of use are also applicable to other embodiments described below, modifying the aspects that need to be modified due to physical limitations.

In all embodiments, the two supports 302 can move together, that is, being at the same point of their respective railings, or they can move independently, thus forcing the user to move from left to right to avoid them.

In Fig. 3A the arms 303 are closed because the user 101 is keeping the ball 104 away from them. Figure 3B illustrates the situation in which the user 101 has taken the ball 104 too far and the arm 303a has been fired to impact it.

Although both Figures 3A and 3B show cameras to identify the position of the ball and / or the user, there may be other systems to identify said positions without losing the essence of the invention. For example, a sensor can be installed on brackets 302, or even on arms 303, that detects the presence of the balloon. As in other embodiments, if the user is standing driving the ball, the elements 302 can approach it to generate a stimulus that generates a behavior, in this case elusive.

In addition to the previous embodiment, all the embodiments shown in the main applications No. P201600526 and No. P201601020 are adaptable to a road on the ground without adding a structure that allows the mobility of the elements that need it.

For example, in the embodiment shown in Figure 4 there is only one support 302, which supports two mechanical arms 303a and 303b. In addition, this embodiment also comprises a support 401 that holds a computer 402 that has a screen 403 that shows the user cognitive activity, which is linked to the mechanical arms 303 and the displacement of the support 302. On screen 403 they will appear for example images of other players whose perceived distance is related to the distance at which the mechanical arms 303 are. In this embodiment, the computer 402 also performs the functions of the computer 214.

In another example, in the embodiment shown in Figure 5, there is an elongated bar 210 of 50 meters that supports a bar 209 that can move in the direction 211, which in turn supports a support 501 that supports a mechanical arm 303 and a doll 304. The support 501 can move in the direction 502 with respect to the bar 209, so that combining said movement with the movement of the bar 209 along the direction 211 can give rise to an arbitrary combined movement 503 with respect to the user 104. We consider it obvious that this embodiment is very similar to the embodiment shown in Figure 2. As in other embodiments, the user may stand still and element 303 and 304 may approach it to generate a stimulus that generates a behavior, in this dodge case.

In the embodiment shown in Figure 6A, the elements presented to the user 104 are attached to a vehicle 601 by an articulated arm 602. If the vehicle moves with wheels 603. If the user moves in the direction 604, the vehicle generally advances in that direction 604 or can be stopped and advanced towards the user. If the user is standing driving the ball, the vehicle 603 can approach the user to cause a stimulus and modify its behavior, or the vehicle may not move and simply approach the obstacles 201. In Figure 6A the elements presented to the user are obstacles 201, but they can be elements that can impact on the ball 104 such as the mechanical arms 303. In a variant of this embodiment, shown in Figure 6B, the vehicle 601 travels along guides 605 to ensure that the address is correct without requiring excessive attention from a person. The arm 602 and the joints and elements that support the elements 201 (or that hold the mechanical arms 303 in another embodiment or that generally support the generic object that is presented to the user) allow these elements to move freely longitudinally and transversely with respect to the vehicle 601 within the limits marked by the size of the parts that compose them.

In all cases, the dolls can be different or be oriented in another direction, for example, they can be oriented as if they were looking to the side, or even looking in the same direction as the user.

Likewise, there may be other embodiments, which are not shown in the Figures, in which the elements presented to the user are cones, or another object, which has wheels and can change position when approaching the user. In an extreme case, they could even be drones that are kept at a medium height and whose propellers are properly covered so as not to harm the user. Performing training exercises with different types of obstacles helps the user develop a capacity for perception that is independent of the obstacle or generic element that is presented.

In another embodiment, illustrated in Figure 7, the user 101 is throwing a basketball 104 instead of driving a soccer ball while traveling along a path 102. Obstacles 201a and 201b are presented on the road and the The user has to get around them just like a user who drives a soccer ball (Figure 2, for example) has to get around them. In the different embodiments in which the user moves along a path, the operation is the same as when the user drives a soccer ball, except for situations in which there is some limitation. For example, it is much more difficult to perform mechanical arms 303 to impact the ball. And in the same way, the user 101 can advance along a road or can stand on the road and avoiding obstacles 201 that approach it.

There are other differences regarding the main requests that are based on treadmills to help a user train the ball. Although various embodiments of the current invention and of the main applications can be used on a non-motorized belt, the embodiments described generally refer to motorized tape apparatus.

In an embodiment based on a motorized belt apparatus, the user can modify the speed of the belt by using the speed at which it runs on the belt as described in the main applications. For example, with reference to Figure 8, in which a user 101 is running on a tape apparatus 801 and driving a ball 104, if the support 302i approaches the user along the path 802 and the user reduces his running speed , the speed of the tape will also be reduced. In a variant of the present application, the support 302i will also reduce its approach speed to the user 101, or even move away from it. This serves to simulate what would happen if the user 104 were ahead of him would approach with a lower relative speed, or perhaps even move away.

In another embodiment, illustrated in Figure 9A, the user 101 bounces a basketball 104 while running on a treadmill 801, while it is located near a side end of the belt 901 and is bouncing the ball out of the belt in a static zone 902, while the ball follows an approximate trajectory 903. This training mode brings several benefits. One of them comes from the fact that in a motorized treadmill the user performs a greater number of steps per minute than if he were running in normal terrain. Due to this, this embodiment helps the user to decouple the movement of the arms when bouncing the movement of the legs when running. The user is learning to drive both a rhythm to dribble the ball 104 and a different, and generally high, rhythm to move the legs. In addition, it is possible to program the tape apparatus 801 to change the speed of the tape 901 and the user must adapt to different situations without losing control of the ball 104.

The main problem with this embodiment is that the ball bounces vertically on the surface 902, and if the user 101 does not move the hand, the ball tends to return to that position. However, when the user is running, if the person bounces the ball vertically, the ball will be left behind by its inertia instead of following the user, and in addition to bouncing on the ground will suffer some friction force that will delay it more .

To compensate for these two effects: inertia and friction with the ground, the embodiment of Figure 9B adds elements 904 and 905 that create an air curtain 906 that will propel the ball in the direction of the curtain 905, and which will also tend to cause that the ball rotate on itself in the same direction it would if it bounced on the ground. Element 907 serves to better contain the air curtain 906. This element 907 is optional and may have a height that will depend on the design. Element 904 emits air and element 905 sucks it to better direct the air curtain 906. Other arrangements of these elements are possible to create the air curtain. For example, element 907 cannot be placed, and element 905 cannot be added, and only element 904 can be left. In addition, the elements used may have a greater height to impact the ball for a greater distance.

Another advantage of this embodiment is to use an elastic ankle band 1001 as seen in Figure 10 to put even more intensity on the pace of movement of the legs and further decouple the movement of the arms from the movement of the legs.

Also, a computer 402 with a screen 403 can be added as shown in Figure 11, so that the user can perform cognitive activities that may be related to the speed of the tape. As in the case of football described in the main applications No. P201600526 and No. P201601020 and in this document in Figure 4, the screen 403 can show game situations in which players appear whose distance to the user 101 may be different, and force to accelerate or slow the pace of the race. Or these players can force you to modify some pattern of their behavior, such as getting ahead on the tape or delaying it (if the tape is fixed speed) or bouncing higher or lower. The computer is compatible with the realization whether a 906 current is created or not.

In other embodiments based on a treadmill apparatus, the treadmill apparatus is included in a CAVE (Cave Automatic Virtual Environment) environment comprising walls on which images of an environment are projected. This environment evolves as the user runs, so that the user has the illusion of advancing in that environment.

The embodiments illustrated in this document in which the user runs on a treadmill apparatus will generally be carried out so that the user wears a safety harness attached at some high point.

Finally, the invention can be interpreted either as a system or as a method.
