Description

[0001] DESCRIPTION

[0002] TITLE: Football Player Accessories and Accessory Sets

[0003] The present invention relates to an accessory and a set of accessories for a football player.

[0004] According to the IFAB (International Football Association Board), the institute in charge of the rules of football worldwide, and in particular according to rule 12 "Fouls and Misconduct: Handball", there is a foul if a player: deliberately touches the ball with the arm or hand, for example with a movement of the arm or hand towards the ball; touches the ball with the arm or hand having artificially increased the surface area covered by his body.

[0005] A player is considered to have artificially increased the surface area covered by their body when the position of their arm or hand is not a consequence of their body movement in that specific situation or is not justified by such a movement. Therefore, determining whether a handball is a foul essentially hinges on the intention of the player who touched the ball with their hand.

[0006] The awarding of handball penalties is therefore often left to the referee's discretion and varies from one referee to another. Consequently, the awarding of handball penalties is often a source of debate.

[0007] The aim of the invention is therefore to offer an accessory for a football player to simplify the arbitration of handball fouls.

[0008] To this end, the invention relates to an accessory for a football player, comprising: a support, removable, suitable for being slipped around at least one thigh of the player, and a gripping handle, attached at two ends to the support, so as to form a loop for passing part of a hand of the football player.

[0009] Thanks to the accessory, particularly the grip, the referee can easily determine the player's intention with a clear view of the player's upper limbs, especially their arms and hands, thus simplifying the decision regarding a handball. The referee can assume that a player gripping the handle intends to keep their hand and arm close to their body, and therefore any contact between their hand or arm and the ball will be unintentional. Furthermore, the invention, when used during repeated training sessions, helps players develop the habit of keeping their hands pressed against their thighs, leading to an automatic, unconscious movement during a match, even if they are not using the accessory. This reduces the risk of a handball.

[0010] According to other advantageous aspects of the invention, the accessory comprises one or more of the following features, taken individually or in all technically possible combinations: the gripping handle is made of an elastically deformable material, preferably elastane; the gripping handle is an elastic band; the elastic band has a band width of between 3 centimeters and 8 centimeters and a band length of between 12 centimeters and 20 centimeters; the accessory comprises a first part comprising an on-board unit, including at least one short-range communication module;The accessory includes a second part which is placed near the wrist of the football player, which includes an onboard unit comprising at least one short-range communication module such that the short-range communication module of the onboard unit communicates with the short-range communication module of the onboard unit; the support is a garment comprising a belt and two legs, the accessory comprising two gripping handles, each gripping handle being respectively attached by both ends to a respective leg of the garment; each of the gripping handles is positioned at a distance from the top of the garment of between 10 centimeters and 25 centimeters; each of the gripping handles is removable from the support; the accessory comprises a first part comprising two onboard units, each comprising at least one short-range communication module;The accessory includes a second part, itself in two parts which are placed near the wrists of the football player, which include onboard units which each include at least one short-range communication module, such that the short-range communication module of the onboard unit communicates with the short-range communication module of the onboard unit and the short-range communication module of the onboard unit communicates with the short-range communication module of the onboard unit; the support is an elastic band configured to be tightened around the thigh of the football player; the band has a band width of between 5 centimeters and 10 centimeters, preferably equal to 8 centimeters, and a band length of between 50 centimeters and 70 centimeters, preferably equal to 60 centimeters.

[0011] The invention also relates to a set of accessories comprising two accessories as described above, each of the accessories being respectively configured to be slipped around one leg of the football player.

[0012] The invention also relates to a system which includes an accessory and a processing unit adapted to process data from short-range communication modules to determine whether the football player is using the grip handle(s).

[0013] The invention will become clearer upon reading the following description, given solely by way of non-limiting example, and made with reference to the drawings in which:

[0020] [Fig. 7] Figure 7 is a view of the accessory in Figure 6 worn by a player.

[0021] [Fig. 8] Figure 8 is a view of the accessory visible in Figure 3, to which the part including the on-board unit has been added;

[0022] [Fig. 9] Figure 9 is a view of the part of the accessory worn by a football player;

[0023] [Fig. 10] Figure 10 is a view of the accessory in Figure 6, to which has been added the part including the onboard units and the player's arms which carry at the wrists the part of the accessory which includes onboard units.

[0024] A set 10 of accessories 15 for a football player 17 according to a first embodiment is shown in figures 1 to 5. The set 10 comprises two accessories 15, each of the accessories 15 being configured to be put on around a respective thigh of the player 17. The accessories 15 are symmetrical with respect to a plane of symmetry 20 of the player 17.

[0025] Figures 2 to 5 represent accessory 15 on the left. Its description is transposed to the accessory on the right, by symmetry with respect to plane 20. Accessory 15 on the left includes a removable support 25 designed to be slipped around the left thigh of player 17.

[0026] The support 25 is advantageously an elastic band 30 configured to be tightened around the thigh. Thus, thanks to the elasticity of the elastic band 30, the support 25 adapts to the movements of the player 17, remains in position on the player's thigh 17 and does not hinder their movements.

[0027] The elastic band is, for example, made of elastane or any other elastically deformable textile material.

[0028] The elastic band 30 has, in this example, a rectangular shape delimited by two long edges 35 parallel to each other and by two short edges 40 parallel to each other, perpendicular to the long edges 35 and connecting respectively one end of one long edge 35 with one end of the other long edge 35. Each short edge 40 delimits respectively a first end 45 of the elastic band 30 and a second end 50 of the elastic band 30.

[0029] The elastic band 30 comprises a first face 55 and a second face 60 opposite the first face 55. The first and second faces 55 and 60 are delimited by the long edges 35 and the short edges 40.

[0030] The elastic band 30 advantageously has a band width 65, measured between the two long edges 35 parallel to the short edges 40, of between 5 centimeters and 10 centimeters. The band width 65 is preferably equal to 8 centimeters.

[0031] A length of the elastic band 30, measured between the short edges 40 parallel to the two long edges 35, is advantageously between 50 and 70 centimeters. The length of the band 70 is preferably 60 centimeters. The dimensions of the elastic band 30 ensure that the accessory 15 can be used by a player 17 regardless of their build, and more specifically regardless of their thigh circumference, as they cover all thigh sizes of 17-year-old football players. The accessory 15 is therefore suitable for both children and professional 17-year-old players.

[0032] In this example, the accessory 15 includes a fastening system 75 with textile loops and hooks. The fastening system 75 comprises a first textile strip 80 including textile loops, not shown, and a second textile strip 85 including hooks, not shown, suitable for hooking the textile loops.

[0033] The first strip of fabric 80 is attached, for example sewn, to the first side 55 of the elastic band 30 from the first end 45 and extends along the length of the band 70. A length of fabric band 82, measured parallel to the long edges 35, is between 20 centimeters and 30 centimeters and is preferably equal to 25 centimeters

[0034] The second textile strip 85 is fixed, for example sewn, onto the second side 60 of the elastic band 30, near the second end 50.

[0035] Player 17 puts on accessory 15 by wrapping and tightening the second side 60 of the elastic band 30 around his thigh as shown in Figure 4. Accessory 15 is held in position by fastening system 47 as shown in Figure 3. The length of textile band 82 ensures adaptability of the fastening system 75 regardless of the footballer's morphology.

[0036] Accessory 15 also includes a 90 grip handle.

[0037] The grip handle 90 is, in this example, a third strip of textile 95 delimited by a third end 100 and a fourth end 105. The third and fourth ends 100 and 105 are attached, in this example sewn, to the support 25 so as to form a loop 110 through which part of a hand of the football player 17 passes.

[0038] The 90 gripping handle is advantageously made of an elastically deformable material, preferably elastane.

[0039] As an alternative not shown, the 90 handle can be fixed to the support by a technique other than sewing, for example by gluing, welding or riveting.

[0040] The gripping handle 90 is advantageously an elastic band 115. The elastic band 115 has a length 120, measured between the third and fourth ends 100 and 105, of between 12 centimeters and 20 centimeters. The elastic band 115 has a width 125, measured perpendicular to the length of the band, of between 3 centimeters and 8 centimeters.

[0041] The third and fourth ends 100 and 105 are, in this example, sewn together so that the ribbon length 120 is parallel to the band length 70.

[0042] In the unshown variant, lengths 70 and 120 are not parallel. In other words, the handle extends at an angle between the long edges 35.

[0043] An accessory 15 is slipped onto each thigh by the player 17, so that its gripping handle 90 is in line with the player's arm, as shown in Figures 1 and 2. Thus, the player 17 can easily slide their hand into the loop 110 or grasp the gripping handle by squeezing their four fingers other than the thumb around it, as shown in Figure 2. When the player 17 grasps the gripping handle 90, they are in a natural position that does not hinder their movement. Therefore, during a phase of play, the player 17 positions themselves and moves in relation to a ball 127, focusing their attention on the ball, so that they are not focused on the position of their hands relative to their body.

[0044] The grip handle 90 represents a target for the hand of player 17 in football. Player 17 must grasp the grip handle as shown in Figures 1 and 2, or slide their hand into the passing loop 110, to demonstrate their intention to keep their arm and hand close to their body. Therefore, if the ball is touched by player 17's hand or arm, with their hand either in the passing loop 110 or grasping the grip handle 90, a referee can easily rule the situation as not a handball. Accessory 15 thus facilitates decision-making and the ruling of handball offenses. Furthermore, accessory 15 also serves an educational purpose. Indeed, since the grip handle 90 is a target for the hand of player 17, player 17 using accessory 15 in training will have automatic responses and will instinctively reproduce the same movements in a match, even if he is not wearing accessory 15.Thus, the use of accessory 15 in training will limit hand errors during matches and the intentions of player 17 will be more easily identifiable for the referee.

[0045] As an alternative, not shown, the grip handle is made with a rope attached at two ends to the support 25, so as to form a loop through which part of a hand of the football player 17 passes.

[0046] In an alternative not shown, the 90 fixing handles are removably fixed to the support 25, for example by a hanging system using textile loops and hooks or by snap buttons.

[0047] Figures 8 and 9 illustrate the accessory 15 for football player 17 according to a second embodiment of the invention. The accessory 15 comprises two parts, 15a and 15b respectively, part 15a being identical to the accessory 15 of the first embodiment except for the features described below.

[0048] The features described below relate to an accessory 15, according to a second embodiment, for either of the two legs of the football player 17; the same features apply to a second accessory 15 used for his other leg. Part 15a of the accessory 15 comprises a textile part 130 and an embedded unit 131 attached removably or permanently to the textile part according to the first embodiment.

[0049] Optionally, the on-board unit 131 is fixed to the support 25 opposite the center of the inner face of the gripping handle 90.

[0050] The onboard unit 131 includes at least one short-range communication module.

[0051] Part 15b of accessory 15 is a device, removable or not, which is placed near the wrist of the football player 17, on the same side where part 15a is placed.

[0052] Optionally, part 15b of accessory 15 is a wrist cuff.

[0053] Part 15b of accessory 15 includes an on-board unit 132 attached removably or not to accessory 15b.

[0054] The on-board unit 132 includes at least one short-range communication module, an inertial measurement unit (IMU), a storage unit that records the various data from the modules and units, and a communication module.

[0055] According to one embodiment, the short-range communication module of the onboard unit 131 and of the onboard unit 132 are near field communication modules known as "Near Field Communication" or "NFC".

[0056] The inertial measurement unit (IMU) includes an accelerometer.

[0057] The storage unit allows the accelerometer data to be stored and whether the two NFC modules are in communication.

[0058] The communication module is configured to transmit data to an external computing device in real time and wirelessly.

[0059] The short-range communication module of onboard unit 131 communicates with the short-range communication module of onboard unit 132.

[0060] The accelerometer is capable of measuring the acceleration of the arm of football player 17 at any given moment.

[0061] The data on the acceleration of the arm of football player 17 and information on whether the two NFC modules are communicating or not are stored on the storage unit.

[0062] The data on the acceleration of the arm of football player 17 and information on whether the two NFC modules are in communication or not, are sent with the communication module to the external computing device.

[0063] The acceleration data of player 17's arm is processed by an external processing unit, and the results are stored on an external storage unit accessible at any time from the external computing device. Data from the two NFC modules, and information indicating whether these two modules are communicating, are processed by an external processing unit to determine if player 17 is using the 90 grip; the results are stored on an external storage unit accessible at any time from the external computing device.

[0064] The data on the arm acceleration of football player 17 and information on whether he is using the 90 grip handles or not are accessible at any time from an external computer device.

[0065] Alternatively, not shown, the onboard unit 132 also includes a GPS module and / or a processing module.

[0066] The GPS module is a device that allows you to know the position of player 17 in football on the field.

[0067] Alternatively, not shown, the inertial measurement unit (IMU) includes an accelerometer and a gyroscope.

[0068] Alternatively, and not shown, the storage unit can also store data from the GPS module.

[0069] Alternatively, and not shown, the storage unit that records the various data from the modules and units is external.

[0070] Alternatively, not shown, the processing phase of the different data is done with the processing module of the embedded unit 132.

[0071] The data processed by the processing module of the embedded unit 132 is sent to the external computer device by the communication module.

[0072] The data is stored on a storage unit accessible at any time from the external computer device.

[0073] Alternatively, and not shown, the communication module does not transmit data from the different modules in real time.

[0074] The data is stored on the storage unit of the embedded unit 132 until it is all transferred later to the external computing device.

[0075] The means of communication between the storage unit of the embedded unit 132 and the external computing device can be wired or wireless.

[0076] Alternatively, but not shown, the storage unit records IMU data when there is no communication between the short-range communication modules of onboard unit 131 and onboard unit 132. It stops recording accelerometer data when the distance between the two short-range communication modules is small enough for them to establish communication. Information indicating whether the two NFC modules are communicating or not is not recorded; the communication status is inferred from the presence or absence of accelerometer data.

[0077] Alternatively, and not shown, with the exception of the short-range communication module and the accelerometer, all other modules and units of the onboard unit 132 are no longer present in the onboard unit 132 but are included in the onboard unit 131. Figures 6 and 7 illustrate a football player accessory 1015 according to a third embodiment of the invention, the accessory 1015 being identical to the accessory 15 of the first embodiment except for the features described below. The reference numerals for the accessory 1015 correspond to those of the accessory 15 when the referenced element is unchanged. The reference numerals are increased by 1000 when they designate comparable elements that have been modified in the accessory 1015.

[0078] Accessory 1015 includes a support 1025. Support 1025 is advantageously a garment 1300 intended to cover the lower torso of a player 17. In the example figures, the garment is shorts.

[0079] Alternatively, the garment could be athletic tracksuit bottoms, leggings, or trousers. The information described below for the 1300 shorts can be applied to other types of garments.

[0080] The shorts 1300 comprise a waistband 1305 and two legs 1310. Each of the legs 1310 distinctly forms, at a lower end 1311 of the shorts 1300, a leg opening 1312. The legs 1310 extend from the lower end 1311 towards the waistband 1305 and meet towards each other, so that the two leg openings 1312 form a single torso opening 1313. The waistband 1305 delimits the torso opening 1313.

[0081] Football player 17 puts on the shorts 1300 by placing each of his legs into one of the legs 1310 of the shorts 1300 and pulling the waistband 1305 up to his waist.

[0082] Advantageously, the accessory 1015 includes two grip handles 90, each of the grip handles 90 being respectively attached by the third and fourth ends 100 and 105 to one of the legs 1310 of the shorts 1300. The grip handles 90 are attached to the shorts 1300, so that each of the passing loops 110 respectively formed by the grip handles 90 are in line with the arms of the player 17. In particular, the grip handles 90 are attached on the outside of the legs 1310, opposite each other. Advantageously, each of the gripping handles 90 is positioned at a distance 1315 from the top of the shorts 1300, i.e. from the upper edge of the waistband 1305, measured between the long edge 35 nearest to the waistband 1305 and the top of the shorts 1300, between 10 centimeters and 25 centimeters.

[0083] The distance 1315 ensures a positioning of the grip handles 90 so that player 17 can easily slide part of his hands into them, more particularly his fingers in the example of figure 7. The distance 1315 varies according to a short size 1300 and the standard arm length of player 17, for a given short size.

[0084] The accessory can also be made to measure, especially for a professional player, to be adapted to the player's morphology. For example, the shorts are adapted to the circumference of the player's thigh and the distance 1315 is adapted to the length of his arms.

[0085] Advantageously, the gripping handles 90 are removable from the support 1025, in this example the shorts 1300. The accessory 1015 includes, for each gripping handle 90, a fastening system 1320 consisting, in this example, of two snap fasteners 1325. A first part 1330 of each of the two snap fasteners 1325 is attached to the shorts 1300 and a second part 1335 of each of the two snap fasteners 1325 is attached to the third end 100, respectively to the fourth end 105.

[0086] As an alternative not shown, the 1320 hanging system is a hanging system using textile loops and hooks.

[0087] In an alternative not shown, the 90 attachment handles are permanently fixed to the 1300 shorts, for example, by sewing. The other methods of attaching the 90 handles considered for the first embodiment are also usable.
