Description

Sports facility TECHNICAL SECTOR The present invention relates to a sports facility, which can be either fixed or portable, specially designed for the practice of a new ball / racket sport. The object of the invention is to provide an accessible, dynamic and balanced sporting experience, combining skill, strategy and strength, through a technical system different from any other racket sport. More specifically, it is a series of components that are easily installed and optionally uninstallable on any flat surface, in minimal time, thus offering the practice of a new economical, active and anti-stress sport / game, easy to practice by people of all ages and physical conditions. The installation of the invention is suitable for playing with family, among friends, in private homes, in parks with play areas, country houses, rural houses, campsites, municipal sports complexes, special areas with a track on the beach, chalets, associations, sports and recreational activities, educational centers (schools, institutes) and even in special or adapted fields, to hold official competitions. BACKGROUND OF THE INVENTION In the field of practical application of the invention, the closest antecedent to the invention could be cited as the game of tennis, in which, if practiced non-professionally, a lot of time is usually wasted picking up the balls. EXPLANATION OF THE INVENTION The proposed sports facility fully and satisfactorily resolves the aforementioned problems, based on a simple but effective solution. To this end, the installation of the invention itself, together with a flat surface of suitable dimensions on which to be applied, determines a new sport / game in which the players pass the ball from one field to another by hitting it with a padel-type racket, overcoming the net that is established in the central area of ​​the court and trying at all times to ensure that the ball does not leave the vicinity of the playing field. The main feature that makes this sport unique is that the ball is equipped with a string, which, once the ball crosses the field and the string is fully taut, creates a rebound effect that provides a vast array of playing possibilities. The ball with the string is in turn attached to a compensating string, which is located above the net, parallel to it. The physics of the ball's rebound movement is conditioned by the tension of the compensating thread, which is controlled by two weights that will rise and fall counteracting the rebound force of the ball. More specifically, the installation of the invention involves a pair of masts that can be fixed, specially designed for sports centers for the pre-designed use of the game / sport, anchored, designed to allow the movement of the game masts from one place to another by being foldable, or mobile, designed with wheels to move them in sports spaces where multiple sports are practiced. A net is mounted on the masts, as well as a compensating wire, associated with respective end counterweights. The compensating string has two main functions. First, it provides the ball with a sliding guide located just above the net. Second, it counteracts the force and rebound of the ball once the string is fully taut, by means of a system of counterweights at each end of the string. The ball used is a standard padel or tennis ball, but with the unique feature of being attached to a string. Inside the ball, there is a rotating system to prevent the string from tangling and ensure that the game proceeds smoothly without interruptions. The ball's string can have different lengths depending on the game mode. The net used for this game also has specific dimensions and special characteristics. Just like the ball string, the net is placed at different heights from the ground, depending on the game type (age / number of players). The racket used can be any type of conventional racket, such as a padel racket, without special features.

Figure 10 shows, finally, a perspective detail of one of the mobile masts planned in the installation of Figure 9. PREFERRED EMBODIMENT OF THE INVENTION In view of the figures described, it can be observed how the installation of the invention is constituted from a network (1) that is linked at its ends to a pair of vertical masts (2-2-2), which, according to the different embodiment variants provided for them, these can have a fixed, lockable-unlockable, or mobile character, as will be seen below. In either case, a compensating thread (3) is arranged parallel to the net, which is linked by means of pulleys (4) provided on the masts (2-2-2) to respective end counterweights (5). A sliding ring (6) is attached to the compensating thread (3), as shown in detail in Figure 7, which includes a hook (7) to which the end of a thread (8) is attached, which is linked at its other end to the ball (9), as shown in Figure 6. The ball will include a hole (10) for the passage of the thread (8), ending in a knot (11) after passing through a washer (13) and a sphere (12) that determine a rotating system to avoid tangles in the thread and facilitate that the game does not have incidents that stop the match. From this structure, when the ball (9) is hit, when it reaches the full extension of the thread (8), it will pull on the compensating thread (3), against the tension of the counterweights (5), being able to move axially on said thread by virtue of the configuration of the sliding ring (6), which generates a new range of possible bounces / trajectories of the ball that did not exist until now, which gives the game a greater appeal and capacity for the development of new skills. As previously stated, the ball string can have different lengths depending on the game mode, as well as the height of the net. By way of example only and not as a limitation, the following dimensions could be established: • Net length (1): 9 meters. • Network width (1): 1 meter. • Weight: 1250g + / - 200g • Grid configuration (1): 12.5mm squares. • Net height (1) 1.70 meters for those over 13 years old. • Net height (1) for children under 13 years old as well as people in wheelchairs, 1.30 meters. • Length of the ball string (8) (9) for ages 13 and over: or For individual 7 meters. or For doubles 7.5 meters. • Ball string length (8) for children under 13 and wheelchair users: or For individuals 6.5 meters. or For double 7 meters. • Dimensions of the playing field: o Width of the playing area: 12.4 meters. o Width of the 2x2 field: 10 meters. o Width of the 1x1 field: 9 meters. o Length of the playing area: 20 meters. or Length of the service zone: 2.9 meters. or Width of the service zone: 4.4 meters. Regarding the three planned mast configurations (2-2-2), in the embodiment variant of figure 8, the masts (2) are fixed, so they have been specially designed for tracks predestined for the use of the specific game. In this type of structure, the mast can be a tubular profile of aluminum or iron, which is buried approximately 25 cm in the playing field, so that it cannot be moved or transferred while, favorably, it is not necessary to use tensioners to give rigidity to this structure. In this case, it has been planned that the pulleys (4) from which the counterweights (5) of the compensating wire (3) hang are arranged externally to the mast. For this model, a support (14) attached to the mast by means of a pin is required to hold both the net and the compensating wire. The support has a pulley (4), which allows the compensating wire to slide as the counterweights (3) located at its ends are raised and lowered. According to the embodiment shown in figures 1 to 5, the masts (2) can be anchored to the track, in which case said masts (2) will have a telescopic character, adjustable by means of a tightening screw (15) which allows not only the height of the net to be regulated, but also to offer a smaller volumetric occupancy during its transport or storage. It is a very lightweight structure because it is made of aluminum. The mast of the anchored structure has two lateral tensioners (16) whose main function is to hold and provide rigidity to the net and compensating wire. A steel shaft (17) is assembled at the bottom of the mast, which is inserted into the hole on the playing surface to secure it. A feature of this type of mast is that it houses the counterweight system (5) for the compensating wire (3). Obviously, the mast will include, corresponding to its upper area, an anchor (18) to which the net is attached. Finally, and in accordance with the third planned embodiment of the masts, shown in figures 9 and 10, the masts (2) may have a mobile character, including a lower structure with wheels (19) and also having a telescopic configuration, adjustable by means of the corresponding tightening screw (15), and the same internal structuring of the counterweights (5) of the compensating wire (3) and means of fixing the net. This structure can be easily moved to all types of playing fields that have the necessary dimensions to be able to practice the game. In order to fix the position of the structure, the wheels have brakes that must be activated once the masts are located in the fixed position on the playing field. In this case, it is not necessary to use a lateral tensioner to give rigidity to the structure. Thanks to the robust design of this structure, once the game components are assembled, the side mast continues to maintain its perpendicularity with respect to the ground. The mobile structure has at least one pair of horizontal beams that allow both masts (2-2) to be joined by means of respective horizontal bars (20), thus allowing the movement of the entire structure to be synchronized. The material of the mobile structure can be iron, aluminum, or both. Finally, it only remains to point out that, in case the ball thread could be damaged, additional balls or threads can be placed on the ends of the compensator thread (3), linked to said thread through the corresponding sliding rings (6) as shown in detail in figure 7.
