[0030] While the making and using of various embodiments of the present invention are discussed in detail below, it should be appreciated that the present invention provides many applicable inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed herein are merely illustrative of specific ways to make and use the invention and do not delimit the scope of the invention.

[0031] To facilitate the understanding of this invention, a number of terms are defined below. Terms defined herein have meanings as commonly understood by a person of ordinary skill in the areas relevant to the present invention. Terms such as “a”, “an” and “the” are not intended to refer to only a singular entity but include the general class of which a specific example may be used for illustration. The terminology herein is used to describe specific embodiments of the invention, but their usage does not delimit the invention, except as outlined in the claims.

[0032] In response to the escalating demand and the consequent shortage of available courts, the inventors introduce the Digital Racquet Sports System. This innovative solution offers a space-efficient alternative, occupying just one-tenth of a typical Pickleball Court, thereby providing a compact yet versatile environment for recreation and training.

[0033] As embodied and broadly described herein, one aspect of the present disclosure provides an all-in-one, modular sports-technology system, the system consisting essentially of: (a) an impact-resistant simulator screen configured to display a digital court for racquet-sport play or arcade-style target games; (b) an integrated sensor array operatively coupled to the screen for detecting ball-impact location and trajectory, the array being in three-way communication with (i) the screen sensors, (ii) a proprietary “smart” ball launching device formed by retrofitting a conventional launcher, and (iii) wireless control firmware that synchronizes and adjusts feed parameters in real time; (c) control electronics and software that coordinate the sensor array, smart ball launching device, and user interface, thereby enabling single-user or multi-user sessions for training, fitness, or entertainment; and (d) a modular support structure that houses and aligns the simulator screen, sensor array, projector, ball receptor assembly, and the smart ball launching device, the structure being pre-fabricated with interlocking panels and tool-less or low-tool fasteners so that two installers can assemble the entire unit in a few hours, providing a turnkey, all-in-one solution.

[0034] An all-in-one modular simulator combines a projection screen, optical sensor array, smart ball launcher, gravity-fed ball receptor, and self-supporting frame. Projected targets account for points when struck, while a digital controller synchronizes sensors and launcher to deliver continuous play. Rebounding balls funnel into the launcher, creating a continuous closed loop. The modular, prefabricated frame assembles with case and in just a few hours. The system occupies less than fifty square feet, enabling installation in fitness clubs, entertainment centers, hotels, schools, and residences. Real-time metrics, cloud-based content updates, and remote diagnostics support training, fitness, and entertainment modes for single or multiple users.

[0035] In one embodiment, the present invention encompasses a dedicated space, covering approximately 50, 60, 70, 75, 80, 90, 100, 110, 120, 125, 130, 140, 150, 160, 170, 180, 190, 200 or more sq ft., where players can actively engage with a system designed to facilitate skill development, gameplay refinement, and social recreative play.

[0036] The system has the following components:

[0037] Interactive Screen: The hitting surface (made of a resilient material, such as vinyl, plastic, fabric, cloth, rubber, plastic, foam, a woven fabric, a non-woven fabric, leather, a flexible polymer material, a film, or a composite material that is placed in a way that, e.g., creates no tension). The material is resilient such that, depending on the size and weight of the ball that strikes the resilient screen, the ball will drop within about 1 to 36 inches from the screen, and in certain cases, about 1 to 30, 1 to 24, 1 to 18, 1 to 16, or even 1 to 12 inches from the screen. That is, the resilient screen absorbs, dampens, and / or attenuates the impact of the ball such that the ball falls within the ball recovery or ball receptor area that is located below the screen and extends horizontally between the screen and the user, which area extends about 12, 16, 18, 20, 24, 30, 36, or more inches from the screen, and can extend along the length of the screen and can even extend outside the length of the screen both right and left of the screen 12, 16, 18, 20, 24, 30, 36, or more inches beyond the width of the screen. In some cases, where the device has sides adjacent the screen, then the entire area in which the balls are captured is below the screen.

[0038] FIG. 1 shows one configuration of the overall system 1, which is shown with the device 10 in relation to an enclosure / net 12 and a court surface 14. A player is shown to provide perspective as to the relative size of the system in relation to the court surface 14. Of course, the skilled artisan will understand that the enclosure / net 12 is engineered to restrict the rebound of a ball outside the playing area, that is attenuating any bounce, and thus, capturing most of the balls into the ball receptor described below.

[0039] FIG. 2 shows an example of an interactive screen for use with the present invention. Screen 10 is depicted having a frame 20 in which the sensor array is concealed within the frame. The screen 10 is covered with a material that dampens or attenuates any bounce from a ball striking the screen but also provides a surface on which a projector will display one or more targets (not depicted), which can be dynamic targets, that will be the location toward which a player will direct a ball to strike the screen 10. The target(s) stay in place until such time that the user strikes the screen 10 with a ball at the target, at which time the dynamic targets can change.

[0040] The screen 10 can be an interactive screen that features dynamic targets that move continuously either by time or once they are impacted by the player, these targets can be numerous (See FIGS. 2, 3, 4). FIG. 3 shows one view of the interactive screen in which the user is shown a target 30 superimposed on an image that gives the perception of a three-dimensional (3D) image in the form of a court 32. A timer 34 can show the time that has elapsed since the target 30 has been shown on the screen 10 and that provides the user with, e.g., a countdown during which to strike the target 30 with a ball. Once the user successfully hits the target 30 at a first location, the system moves the target 30 to a new location and reinitiates the countdown of the timer 34 and provides the username 35 and the number of balls that have hit targets or points scored 38. Further, the system can also trigger awarding points to the player upon correctly striking the target 30. The screen 30 that is the hitting surface for the ball can be positioned at any height depending on the type of player (adults, children, wheelchaired) or can be modified in its dimensions to suit the space where it will be placed. Two components of the Interactive Screen can include: (1) to include targets that recognize if the ball in fact hit the target; (2) a surface than restricts / prevents the bounce back of the ball to the player. FIG. 4 shows a version of the screen 10 in which the targets 30 are depicted as hexagons (any shape that is regular or irregular can also be substituted), which can be changed in color to indicate the location of the target 30 and which location changes once the user strikes the target 30. FIG. 5 shows a version of the screen 10 in which the targets 30 are depicted as squares (but can be any shape or form), e.g., for use with children or parties, that also shows the timer 34, a level 37, and hits / misses 39, which are in a different location in addition to the points scored. FIG. 6 shows another screen 10 which depicts a court 21.

[0041] The ball launching device may be connected to a LED light that blinks green when is about to begin to launch balls, remains green while it is launching balls and turns red when the device is ready to launch (in about 1-2 seconds) but not actually launching.

[0042] FIG. 7 shows one embodiment of the ball receptor (50) and the ball launching device 60 that directs balls toward a user. The ball receptor 50 is positioned below and in front of the screen 10 (not depicted) just beneath the lowest part of the Interactive Screen (FIGS. 2, 3). In one embodiment, the ball receptor (50) has roughly the exact same width as the Interactive Screen, and can include a depth of 1, 2, 3, or 4 feet. Its main purpose is to capture balls that upon impact with the interactive screen drop into the ball receptor (50). The material of the screen 20 restricts the bounce from the balls and has a geometry with a downward angle 52 that enables the balls to move to an opening (54) (shown herein generally in the center of the ball receptor (50), but it can be located anywhere in the area in which the ball is captured), of the ball receptor (50) where there is a structure, such as a funnel, that sends the balls back to the ball launching device, which stands on a platform that has a geometry that delivers to an elevation that delivers a launch angle for balls to be hit for players of all skill levels 60. The ball launching device (60) shows below the screen; however, the system can include one or more ball launching devices that can also be located to a side of, or above a player.

[0043] The front of the ball receptor (50) can be covered by a range of materials like vinyl, plastic, fabric, cloth, rubber, plastic, foam, a woven fabric, a non-woven fabric, leather, a flexible polymer material, a film, a composite material, or a net (56) that prevent balls that are aimed below the screen 10 (not depicted) from going below the ball receptor (50). At the center of the net (56) there is an opening (which can be in the shape of a square, rectangle, circle oval, or other shape) that lets through the ball(s) that come out from the ball launching device 60.

[0044] FIG. 8 is an isometric view of one device configuration that shows the relationship of the screen 10, the ball receptor 50, the opening (54), the balls 62, the ball launching device 60, in which the ball launching device 60 is gravity fed the balls 62 and an on (start) / off switch 70. Alternatively, a mechanical ball receptor device operating in the background can deliver balls from ball receptor 50 to the ball launching device.

[0045] FIG. 9 shows one configuration to enable the ball launching device to launch balls with the on (start) / off switch 70 that includes one or more on / off switches 72 and light sources 74 that can alternate between e.g., green and red to let the user know the position of the switch. The green / red lights can also pulse to let the user know that the ball launching device is about to start (giving the user time to get ready) or will be shutting down. In FIG. 8 the on (start) / off switch 70 is depicted adjacent the ball receptor 50 but can be positioned anywhere in or around the court or area of play.

[0046] FIG. 10 shows an isometric view of the device 100, which includes the modular device and is an all-in-one or modular standalone configuration. The device 102 is modular and can be shipped assembled or can be disassembled for shipping and then installed on-site. The screen 104 is engineered to restrict the rebound of a ball, that is attenuating any bounce, and thus, capturing most of the balls into the ball receptor area 106. An opening 108 is positioned such that a ball launching device or multiple machines are positioned to direct a ball toward a player during use. As with the ball launching devices described hereinabove, the same features are available for this more modular standalone configuration. The device 100 can be manufactured from materials that allow use both indoor and outdoor. The sides 110 can redirect the ball toward the screen an ultimately the ball receptor are 106 that includes the ball receptor (not shown in this figure).

[0047] FIG. 11 presents a side view of the modular device 102, detailing the interactive screen 104, ball receptor opening 114, and ball launching device 112 positioned beneath ball receptor area 106. One outer side panel has been removed to reveal the alignment of the ball receptor opening 114 and ball launching device 112. In operation (balls not shown), balls striking screen 104 are captured by receptor 106, funneled through opening 114, and collected in ball launching device 112, which stores multiple balls and relaunches them toward the player-creating a continuous closed-loop of capture, funnel, and launch.

[0048] The ball launching device 112 in this example is shown in the middle of the modular device 102, but the modular device 102 can include more than one ball launching device 112 and the ball launching device 112 can be positioned in any location that permits balls to be directed toward a user, that will allow the use to strike the ball with a racquet or paddle toward the screen 104.

[0049] FIG. 12 shows a close-up, side bottom view of the ball receptor opening funnel 114 and the ball launching device 112 under the ball receptor area 106 that is angled to direct balls into the ball receptor opening 114. In this example, the ball launching device 112 is shown such that a launcher platform 116 creates an angle under the ball launching device 112 to direct the ball upwards. However, a platform is not necessary if the ball launching device 112 can direct the ball in one or more directions, as will be known to those of skill in the art. Examples of ball launching devices 112 capable for a wide range directions, speeds, spin, ball storage, etc., are well known in the art of, e.g., pitching machines and the like, such as those taught in U.S. Pat. Nos. 7,766,770, 7,691,012, 7,980,967, and 8,287,404, relevant portions incorporated herein by reference.

[0050] FIG. 13 shows a version of the projector 120 that is mounted centrally inside the upper section of modular housing 102. Projector 120 casts game imagery and target zones onto the resilient screen. The location where a ball or other object strikes the screen is detected by one or more sensors or an array of sensors in contact with or directed toward, e.g., surrounding the screen, sensors in the screen, sensors behind the screen, by a remote detected that detects where on the screen the ball strikes, using one or more sensors in or on the ball or object, or any combination thereof, which sensors detect the location of an object, such as a ball, striking the screen.
