[0002] Title: Installation for a ball game comprising a return panel with a multifaceted origami-type structure

[0003] Technical field

[0004] The present invention lies in the field of sports and leisure, and more particularly the field of ball games.

[0005] The subject of the present invention relates to an installation for a ball game derived from the technique of football and comprising at least one ball return element.

[0006] The present invention will find numerous advantageous applications in the world of sports and leisure by allowing the deployment of a new sport and / or leisure derived from the technique of football which is intended for all sportsmen and women, whether they are footballers or not. The present invention may be offered by communities in public spaces and municipal sports complexes as well as in private sports halls or even the different types of outdoor accommodation hosting sporting activities.

[0007] The new sport proposed through the installation according to the present invention is derived from the footballer's technique; it can be practiced both outdoors and indoors.

[0008] By sport derived from the technique of football within the meaning of the present invention, is meant in the present description which follows a ball sport which is played with the feet and the head, a football (or equivalent) and which involves the same movements, the same dexterity and the physical and technical skills as football.

[0009] Prior art

[0010] The world of sport and leisure today plays a major role in everyday life.

[0011] This is especially true for a ball game like soccer.

[0012] Football is indeed a universal sport which has a dimension that goes far beyond sport as such.

[0013] A large part of the world's population practices or has already practiced this sport, whether in a sporting or recreational context, at school, in a club or as a hobby.

[0014] Although this sport remains easily accessible (all you need is a ball), practicing this sport requires having a large field with goals and forming two teams with several players. This can be restrictive and the conditions are not necessarily easy to achieve.

[0015] In parallel with this, we have recently seen the craze for padel, a new sport, which is a synthesis of several racket games such as tennis, squash, table tennis and Basque pelota.

[0016] Derived from tennis and racket sports in general, padel is played on a small court (twenty meters by ten meters) surrounded by walls and fences. This recent success lies in particular in the fun nature of playing padel, whose rules are simple and which also allows for a high energy expenditure over a short period.

[0017] This success shows that the population is increasingly looking for new sports and leisure activities, both for fun and to exercise.

[0018] Surprisingly enough, football, a universal sport that everyone can master, has not yet really given rise to any spin-off sports that have achieved the same success as padel. However, attempts to launch one were made in the 1980s.

[0019] In particular, document EP03035444 is known, which discloses a ball game installation.

[0020] In document EP03035444, the installation comprises a rectangular playing field and two return panels located on either side of the field. The two return panels are made of a hard material and each have an outer surface inclined towards the field.

[0021] In this document, each panel is flat.

[0022] The fact that each panel includes a flat surface is presented as essential: the technical effect sought by this flat surface is to ensure that any ball hit on the panel is returned directly by it to the area in a direction that is easy for the player to determine.

[0023] The Applicant submits that the configuration of the installation proposed in this document is very interesting. It allows for a new ball sport.

[0024] On the other hand, the Applicant observes that the installation proposed in document EP03035444 makes the practice of the proposed sport very simple, even too simple. As explained above, the panel with a flat surface is configured in such a way that the ball is systematically returned by the panel in a direction that is easy for the player to determine. This flat surface returns the ball at an angle of reflection that is equal to the angle of incidence. With the flat surface, the player as soon as the ball is hit by his opponent can anticipate the direction of the rebound on the panel to position himself in the associated area.

[0025] The player who has a little practice will therefore be able to very quickly anticipate the area in which the ball will go after bouncing off the backboard.

[0026] So, a player, experienced or not, - having a good reading of the game and good dexterity with the ball will very quickly get tired of this sport.

[0027] The facility described in this document makes the proposed sport unattractive and not very fun.

[0028] The Applicant also submits that the installations disclosed in this document have only been deployed in France, without any real success.

[0029] For these reasons, it seems unwise to seek to redeploy this type of installation identically on a large scale to popularize the practice of the sport envisaged with the installation disclosed in this document.

[0030] The Applicant therefore submits that the facilities proposed in the prior art are not fully satisfactory and do not allow a ball sport which is fun to play.

[0031] Summary of the present invention

[0032] The present invention aims to significantly improve the situation described above.

[0033] The present invention aims in particular to remedy at least one of the various technical problems mentioned above by proposing an installation promoting the appeal of the game by allowing a random nature of the ball's bounce to complicate the game and make it more fun and attractive.

[0034] The subject of the present invention relates, according to a first aspect, to an installation for a ball game comprising a playing field and at least one element for returning the ball onto the field.

[0035] According to the invention, the return element comprises a panel having a surface facing the ground.

[0036] According to the invention, the surface has a multifaceted structure whose facets are inclined relative to each other so that the ball bounces randomly on the surface while heading towards said field.

[0037] It is therefore understood that the surface of the panel facing the field comprises a plurality of facets corresponding to as many rebounding surfaces, each of these facets being inclined relative to each other to complicate the game by multiplying the possible directions of a rebound of the ball on the surface. Thanks to this multifaceted structure, the player can no longer anticipate the trajectory that the ball will take after its rebound on the return element (as he could easily do in document EP03035444), which greatly complicates the practice of the game and makes it much more attractive.

[0038] Here we understand that the surface of the panel extends globally in the same determined plane.

[0039] Since the surface has a multifaceted structure, the surface of the panel does not extend in the same plane in the strict geometric sense. On the other hand, it will be understood that the surface extends in a mean plane, that is to say a median plane corresponding to the average of the planes of each facet. For these reasons, it is indeed the expression "extends globally in the same plane" which can be used to express the fact that the surface extends in such a mean plane.

[0040] Advantageously, the playing field extends in a horizontal plane.

[0041] Advantageously, the playing field comprises at least two straight lines parallel to each other, called end lines, each delimiting the end of the playing field.

[0042] Preferably, the playing field is substantially rectangular in shape, optionally with sides truncated to form an octagon.

[0043] In one embodiment of the present invention, each facet is inclined relative to a first vertical plane perpendicular to the horizontal plane of the playing field and parallel to said end lines.

[0044] Preferably, the inclination of a given facet relative to the first vertical plane is carried out according to a first inclination angle different from that of the other adjacent facets. Preferably, it will be understood that certain facets are inclined upwards and other facets are inclined downwards.

[0045] In another embodiment which can be combined with the previous embodiment, each facet is inclined relative to a second vertical plane perpendicular to the first vertical plane and to the horizontal plane of the playing field.

[0046] Preferably, the inclination of a given facet relative to the second vertical plane is carried out according to a second inclination angle different from that of the other adjacent facets.

[0047] This combination of facets inclined in different directions for adjacent facets makes it possible to have a multifaceted structure configured to multiply the number of possible directions for the rebound of the ball when the ball is struck towards the panel. By adjacent facet, we mean here a facet which is adjacent to another facet of the multifaceted structure. Such an adjacent facet therefore comprises at least one side or edge in common with the facet in question.

[0048] Preferably, the first and / or second angles of inclination are between 5° and 40°, preferably between 10° and 35°. These angle values ​​were preferred because it was found after several tests that they allowed adequate rebound of the ball with a trajectory which allowed the ball to be returned to the field.

[0049] Preferably, the panel is generally inclined towards the playing field.

[0050] Preferably, the panel is generally inclined towards the ground and is sized so that the upper portion of said panel is further forward on the ground than the lower portion of said panel.

[0051] In a particular embodiment, the panel is generally inclined at an angle of between 15 and 25° relative to the first vertical plane, preferably substantially equal to 20°.

[0052] Preferably, each facet has a different geometric shape (i.e., a non-identical geometric shape) from that of the adjacent facets.

[0053] Preferably, each facet is polygonal in shape such that the multi-faceted structure has an origami-like shape.

[0054] Depending on the desired variations, the facets can each take the form of a triangle, a quadrilateral (parallelogram, rhombus, rectangle, square or others), a hexagon or an octagon.

[0055] Preferably, each facet has a rebound surface different from the rebound surface of adjacent facets. It is understood here that the surface area of ​​a facet is different from one facet to another.

[0056] These different preferred variants above, which can be combined with each other, make it possible to make the game more complex by reinforcing the random nature of the ball's bounce on the surface of the multifaceted structure panel.

[0057] In a particular embodiment, the panel is made of a hard material which thus provides adequate rebound.

[0058] Preferably, the panel is made of a rigid composite material based on glass fibers, preferably reinforced with polyester resin.

[0059] Preferably, the panel is made of a material selected from the following materials; wood and its derivatives, metal or alloy such as for example steel or aluminum, tempered glass, plexiglass, plastic and / or its derivatives, concrete and / or fiber concrete. In an advantageous embodiment, the panel comprises an assembly of modular panels including at least one central panel and two side panels on either side of said at least one central panel.

[0060] Preferably, the two side panels are oriented towards the playing field. The return element with a central panel and two side panels oriented towards the field thus has a general shape curved towards the playing field so that the ball coming from the field and striking the panel at any of its points is returned to the field. In a preferred embodiment, the panel is made up of at least three rectangular elements of the same dimensions, equipped with attachment means cooperating for the assembly two by two of said at least three elements so that the elements once assembled form a single homogeneous panel, without discontinuity and the concavity of the two side elements is inverse, forming a rounded part facing the field.

[0061] Preferably, the return element comprises, under the panel, a base whose surface extends in the first vertical plane.

[0062] Preferably, the multifaceted structure comprises at least one facet serving as a target which has a specific color allowing the facet to be identified as a target among the other facets. This is also referred to as a “bonus point”.

[0063] Preferably, each facet serving as a target comprises a sensor configured to determine that the ball has touched the target. The presence of such a sensor may prove useful for automating the calculation of points during a game or match. Optionally, it may, for example, be provided that this sensor is connected to on-board electronics capable of implementing an algorithm configured to calculate a score and increment this score according to the targets touched (occurrence, etc.).

[0064] Optionally, such on-board electronics may be in the form of an electronic card integrated into the panel or in a space dedicated to it. It is also possible to envisage that this electronic card communicates by wireless means with at least one communication terminal such as, for example, that of one of the players. The installation according to the present invention is preferably completed with a central net dividing the field into two zones of equal surface area.

[0065] Preferably, the installation according to the present invention comprises two return elements each placed in the bottom of the field at the ends thereof; it is understood here that these return elements are positioned along the two opposite sides of the field (also called the end line) parallel to the central net. Preferably, each return element is mounted on a support at a determined height above the field. Optionally, this height is a function of the height of the central net. Such a support preferably comprises posts, called fixing posts, which are fixed to the bottom of each end of the field.

[0066] The return element can therefore be rigidly fixed in the ground at the desired location on the playing field.

[0067] Alternatively, the return element may be removable, for example being fixed to a removable basketball backboard type support. Thus, the backboard and its support are light and handy, and the stability of the backboard once placed along the court is achieved by the weighted support structure so that the backboard remains in place when the ball is struck.

[0068] Furthermore, it will be understood that preferably the inclination of the panel, the curvature of the surface of its lateral parts and the height of the central obstacle are such that the panel returns to the zone along which it is located the ball coming from the other zone.

[0069] Preferably the return element has a length approximately equal to that of the bottom of the ground.

[0070] Correlatively, the object of the present invention according to a second aspect comprises a use of an installation as described above for a ball game according to determined rules.

[0071] It will be understood here that the rules do not have to be explained in detail here but advantageously exploit the particular properties of the installation, the return elements and the presence of the central net, which have just been recalled.

[0072] Such an installation can be used indoors for an "indoor" practice, but can also be used outdoors for an "outdoor" practice.

[0073] Thus, through its various functional and structural technical characteristics described above, we have an installation comprising return elements whose surface with a multifaceted origami-type structure with several facets inclined according to different orientations allows a random rebound whose trajectory varies depending on the facet on which the ball will bounce.

[0074] Such an installation will greatly enhance the appeal of the game compared to an installation such as that proposed in document EP03035444. Description of the figures

[0075] Other characteristics and advantages of the present invention will emerge from the description below, with reference to the appended figures which illustrate an exemplary embodiment thereof without any limiting character and in which:

[0088] Detailed description

[0089] An installation according to an exemplary embodiment of the present invention will now be described in the following with joint reference to Figures 1 to 14.

[0090] For the record, it turned out that the installation proposed in document EP0303544 was not entirely satisfactory from a game perspective because players with a little practice were very quickly able to anticipate the trajectory of the ball following a bounce of the ball on the flat surface return panels.

[0091] Thus, the game offered by the installation disclosed in this document lacks appeal and has not achieved the expected success. The object of the present invention is therefore to propose a return solution allowing a random rebound with bonus point zones to make the game offered by the installation more fun.

[0092] Document FR2574304 proposes an interesting ball game installation; in this other document, the ball return elements comprise nets with a concave or convex profile, elastically fixed in a rigid frame.

[0093] The concave or convex profiles of the nets proposed in this document FR2574304 lead to an aerial return of the ball, which allows continuous play without the ball touching the ground.

[0094] Given the particular structure of these nets, the return of the ball is a function of the elastic deformation of both the net and the members fixing the net to its frame. The Applicant submits that this elastic deformation is a function in particular of the force of the ball's strike, the location of the ball's impact on the net and the shape of the net. As indicated in document FR2574304, the angle at which the ball is returned by the net is almost unpredictable, as is the return force which is dependent on the shock-absorbing nature of the net.

[0095] In this sense, document FR2574304 proposes an alternative to document EP03035444.

[0096] The Applicant submits, however, that the installation proposed in this document FR2574304 is costly and requires regular maintenance of the nets, which tend to deteriorate easily due to climatic conditions and deliberate damage by malicious individuals, particularly when used outdoors.

[0097] Furthermore, the Applicant submits that the use of nets involves cushioning the ball when it bounces off the surface of the net, such cushioning due to the elasticity of the nets not being conducive to the game. This will slow down the game when we are looking for a solution aimed at making the game more complex.

[0098] Thus, as with document EP0303544, the ball game proposed in document FR2574304 was hardly more successful.

[0099] The objective here is therefore to propose a solution remedying the various drawbacks raised in the prior art by proposing a fun game which will appeal to all sportsmen and women, both football fans and the uninitiated.

[0100] This objective is achieved by the following example.

[0101] It will be noted at the outset that the present invention can in no way be considered as being limited by this exemplary embodiment of the invention. In this example and as illustrated in particular in Figures 1 to 3 and 10 to 14, an installation 100 comprising a playing field 10 and return elements 20 is provided within the framework of the present invention.

[0102] Here, as illustrated in Figure 14, a playing field 10 can be provided having a substantially octagonal surface approximately seventeen meters long by approximately seven and a half meters wide comprising two zones 11 and 12 of equal surface delimited by a central net 40 placed in the middle of the field 10 parallel to the sides of the field 10 along which two return elements 20 are positioned, each formed by the panels 21.

[0103] In this example, the central net 40 is in the form of a stretched net of the same type as that of a tennis court.

[0104] The maximum height of the 40 net is around ninety-five centimeters for a ground width of seven and a half meters. The 40 net is a ball obstacle.

[0105] In the example described here, a removable installation 100 is envisaged to facilitate assembly / disassembly operations.

[0106] In this example, each return panel 21 is therefore in the form of an assembly of three modular panels including a central panel 23 facing the ground.

[0107] 10 and two lateral modular panels 24 on either side of the central panel 23. In this example, the modular panels are mounted on a support 30 using vertical uprights 31 (or fixing posts) located at the lateral ends of the panel 21. Means of attachment (not shown here) of the modular panels two by two and of the support 30 ensure the assembly and stability of the assembly.

[0108] These are all known means of attachment, for example pins with keys cooperating with holes drilled through the uprights and positioned opposite each other during assembly.

[0109] In the example described here, the lateral modular panels 24 are slightly curved towards the terrain 10. This curvature is inverse for each of the two lateral modular panels 24 so that the panel 21 has a general shape slightly rounded towards the terrain 10 at its two ends.

[0110] In this example, the height of panel 21 is equivalent to that of a football goal, i.e. around two hundred and twenty forty centimetres.

[0111] In this example, each return panel 21 is made of a hard material allowing adequate rebound promoting the transfer of energy when the ball rebounds on the surface 21a of the panel 21. Such a material does not behave like the net of document FR2574304 which deforms elastically under the force of the ball and which ultimately cushions the ball in its rebound phase.

[0112] In this example, a rigid composite material based on glass fibers reinforced with polyester resin was selected for the production of the panels 21. The use of such a material makes it possible to obtain a rigid panel ensuring adequate rebound of the ball and resistant to bad weather and external conditions while being sufficiently light for the assembly to be easy to handle.

[0113] To achieve all of the objectives mentioned above and in particular to design a return surface generating a random rebound, the concept underlying the present invention is to provide return panels 21 having a surface 21a having a multifaceted origami-type structure.

[0114] The origami-like multifaceted structure is characteristic of the present invention.

[0115] Such a multifaceted structure therefore comprises a plurality of facets 22.

[0116] In the example described here and as illustrated in figures 1 to 3, the facets 22 each have a polygonal shape such as for example a triangle, a quadrilateral or even an irregular octagon.

[0117] In this example, the facets 22 each have a distinct geometric shape and offer a different bouncing surface from each other so as to accentuate the random nature of the bouncing. To increase the difficulty, the number of facets 22 can be increased by reducing the bouncing surface of each facet, such as for example a bouncing surface less than one square meter.

[0118] In the example described here, still to complicate the game and increase the random nature of the bounce, each facet 20 is inclined relative to the other adjacent facets (i.e. the facets having a common edge between them) so that the ball bounces randomly on the surface 21a of the panel 21 while heading towards the field 10.

[0119] It is therefore understood that each facet 22 is inclined and that the inclination of each facet 22 is calculated so that the ball after rebounding heads towards the field 10.

[0120] Having a panel 21 whose surface 21a comprises several facets 22 inclined relative to each other generates for the player a great uncertainty in the direction of the rebound; the latter cannot anticipate this direction until the ball has rebounded on the panel 21.

[0121] This structure with several inclined facets 22 significantly increases the playful nature of the game. In this example and as illustrated in figures 4 to 9, the inclination of the facets 22 is done on the one hand with respect to a first vertical plane P2 which is perpendicular to the horizontal plane P4 of the playing field 10 and parallel to the background lines 10a of the field.

[0122] The inclination of the facets 22 according to this first plane P2 is illustrated according to different possible examples in figures 4 to 9.

[0123] This inclination is represented here by the first angle of inclination, noted here a, which according to each variant of figures 4 to 9 is between 10° and 35°.

[0124] It will be understood here that each facet 22 is also inclined at a second angle of inclination (not shown here) relative to a second vertical plane P3 which is perpendicular to the first vertical plane P2 and to the horizontal plane P4 of the playing field 10. This plane P3 is parallel to the side lines of the field 10.

[0125] We therefore have an inclination of the facets 22 according to two vertical planes P2 and P3 which are perpendicular to each other.

[0126] This multifaceted origami-type structure with 22 facets of varied geometric shape and inclined to each other (according to planes P2 and P3) makes it possible to constitute a dimensional bouncing surface which is random and which is therefore conducive to play by encouraging play by making the anticipation of the twists more complex.

[0127] Such an installation 100 according to the present invention presents good prospects for adhesion and success among all sportsmen and women (both football fans and non-fans) who will find a fun ball sport. In particular, it will provide former football players with playing sensations just as padel allows a former tennis player to enjoy playing with a racket.

[0128] The invention described above may be used under the following conditions (figure 14): two players or two groups of players are on the court 10 respectively in their zones 11 and 12. During the course of the game, they kick or head the ball from their zone to the opponent's zone over the net 40. When the ball is kicked by a player from zone 11 onto the panel 21 of the opponent's zone 12, the ball is returned by the panel 21 to the court 10 of zone 12 in a random direction depending on the facet 22 on which the ball bounced due to the multifaceted geometry of the panel 21 and its rigid rebound structure.

[0129] Unlike document EP0303544 which proposes central panels with a flat surface, the return of the ball is not predictable by the player due to the multifaceted structure according to the present invention; this multifaceted structure thus gives an additional attraction to the game which did not exist with the installation proposed in document EP0303544. As explained previously, the game in question which is implemented here using this installation 100 includes rules which do not have to be explained but which advantageously exploit the particular properties of the return panels and the presence of the central obstacle which have just been recalled.

[0130] Unlike document EP0303544, the present invention provides a multifaceted structure which complicates the game by encouraging the ball to bounce in random directions which are difficult for players to anticipate.

[0131] The invention is not limited to the exemplary embodiment of the invention that has been described, but covers all variants thereof. In particular, a single return panel can be placed along a training ground allowing a single player to use the facility.

[0132] The dimensions of the field, the height of the panels and the central net are adapted to the playing conditions, especially if it involves children or adults.

[0133] It should be noted that this detailed description relates to a particular embodiment of the present invention, but that in no case does this description have any limiting character with respect to the subject of the invention; on the contrary, its objective is to remove any possible imprecision or misinterpretation of the claims which follow.

[0134] It should also be noted that the reference signs placed in parentheses in the following claims are in no way limiting; these signs have the sole purpose of improving the intelligibility and understanding of the following claims as well as the scope of the protection sought.
