Definitions

  • the present invention relates to training equipment for ball according to the preamble of claim 1.
  • US patent no. 6,220,974 discloses a device in which a ball is suspended in a frame by strings horizontally and vertically, intended for kick-training. It is furthermore stated that it be appropriate for goalkeeper training and aerobic training. The framework and the way the ball is attached to it, however, offer quite limited possibilities for variation in training.
  • WO publication 01/58 537 discloses a training equipment where a ball is surrounded by a net which is attached to a string which in turn is attached to either a plate or a vertical attachment intended to be screwed into the ground.
  • the equipment also includes a swivel, which will allow the ball to rotate. This equipment provides more variability than the foregoing, but the net that surrounds the ball is in many situations undesirable and ground mounted equipment for tethering the ball involves a risk for athletes to be injured unless the equipment is used solely for kicking a ball at rest.
  • JP 2007082579 describes a device for ball training, utilizing a branched suspension of a vertical elastic line that holds a ball.
  • This system has the advantage over, for example, WO 01/58 537 that it does not include ground-mounted equipment on which athletes can injure themselves.
  • US Patent 5,398,940 describes a device for practicing heading of the ball, where a ball is suspended by a line, which is passed through a tube arranged at a high elevation.
  • the line flexibility is of little importance and it is stated that it may well have a relatively inelastic, rope-like structure.
  • the tube, through which the line is run, is essentially a passive component that primarily provides for height. This equipment does not allow varied training such as passing and kicking a ball in motion.
  • US 7,935,006 deals with equipment of the same general kind as discussed above, with a ball tethered to a line that can be attached to the ball without enclosed the ball in a net or slings that significantly affects the ball behaviour.
  • the line is attached to a handle, and although it is stated that as an advantage thereof that it may be held at different heights to place the ball back at different heights, this is something that negatively affects the athlete's freedom of movement, as well as the risk that the grip slips so the ball continues its path until it undesirably hits an object which may be damaged.
  • US 2011 124442 is another example of known technology in this field. This describes a comprehensive system with two vertical posts carrying a horizontal top rail. From the crossbar is attached two cords which meet in a node corresponding to the case of the above mentioned
  • CN 202478255U discloses training equipment for badminton, where a badminton ball is flexibly suspended from a telescopic rod.
  • the prior art is characterized by the disadvantages, shortcomings or limitations that the equipment provides little versatility, i.e. it is only suitable for a very specific type of training, such as shooting at targets with the designated target point, as well as the use of ground-mounted equipment with which the athletes easily can come in conflict and possibly be injured.
  • the training equipment can be combined with or provided with electronic sensors, preferably combined with transmitters and receivers, which in dependence of certain criteria can give points or score for the quality of the exercise being performed, including the ball's speed and direction and possibly the athlete's energy consumption.
  • the present invention is a.
  • one at least partially elastic line is intended to include that at least a part of the line is elastic, meaning that the line typically is not uniform between the attachment point to the rod and the attachment point to the ball.
  • the present invention provides a device where the ball is free of surrounding net. It is free to be hit from various positions along the ground level, but also to be to be hit when moving either along the ground or at a distance above ground, including with other body parts than the athlete's foot. It is thus possible for example to train heading or cushioning, by first shooting the ball in one direction and then give it a new impact when it returns, be it by foot, hand, head, chest or any part of the body the athlete may desire.
  • the equipment does not include equipment to be placed or mounted on the ground, and thus no danger of injury to the athlete other than the risk which is always present during such physical exercises.
  • the extendable rod is arranged on a cart that is wheeled out on a training field. Depending on which exercises to be performed, this cart can be shielded with cones, ribbons, etc. so that athletes receive a warning if they approach the cart closely.
  • a fixed or stationary structure When, in this document, a fixed or stationary structure is referred to, it primarily refers to structures like a building wall or post for lighting or the like, which are already present at the location in question and which do not have to be carried or placed there in connection with the execution of a workout.
  • a goal for a football or handball court is generally not difficult to move and therefore does not satisfy the strict requirements for what a fixed or stationary structure might be. Nevertheless, such goals can, for the purpose of the present invention, be regarded as existing permanent structures, as they normally are in place and used at the training field independent of any use of the equipment of the present invention, and they have a permanent location, again regardless of the present invention.
  • athletes need to think particularly on the goals and it is not so that the use of goals as a supporting structure for the equipment of the present invention, involves addition of equipment which may represent a hazard to the athletes.
  • Figure 1 shows a first exemplary schematic diagram of the training equipment according to the present invention in a first embodiment.
  • Figure 2 shows a variant of the training equipment shown in Figure 1, shown from another angle.
  • Figure 3 shows a magnified detail of the training equipment shown in Figures 1 and 2.
  • Figure 4 shows a schematic diagram of another embodiment of the training equipment of the present invention.
  • Figure 5 shows a magnified detail schematic view of a third embodiment of the training equipment of the present invention.
  • Figure 6 shows an alternative embodiment compared to the one of Figures 1 and 2.
  • Figure 7 shows yet another embodiment of the training equipment of the present invention.
  • FIGS 8A - E show magnified an example of some details of the equipment of the present invention.
  • FIGS 9A-D show magnified examples of details of the equipment of the present invention, which are alternatives to the details shown in Figures 8A-E.
  • Figure 10 shows a detail of a non mandatory part of the training equipment of the present invention.
  • Figure 1 shows an extendable rod 11 fixed to the crossbar 15 of a goal 14.
  • To the outer end of the extendable rod is attached to one at least partially elastic line 12 which in turn is attached to a ball 13.
  • the line 12 does not have to be uniform in its entire length and the entire line does not need to be elastic.
  • the extendable rod is typically telescopic, but may also have the form of separate parts screwed together, which can be more convenient if one wants to achieve high strength with small dimensions.
  • the extendable rod 11 is shown attached to the target 14 about the middle of the crossbar 15, there is nothing preventing attachment close to the vertical posts.
  • Figure 1 indicates that the extendable rod may advantageously be attached by a fastening mechanism allowing the extendable rod to be pivoted an angle different from 90 degrees in relation to the goal line, and locked in such positions.
  • Figure 1 also provides an indication of the horizontal component of the length (L h ) of the rod 11, which can be for example 8-10 meters.
  • the ball in an arrangement like the one shown here can be used for shots on goal, but also for passes and subsequent goal-attempts, since kicking the ball in the direction of an imaginary side line, will cause the ball comes back, low or high, so that the athlete with or without parrying the ball can try to direct the ball into the goal with any part of the body, including the head. It is also readily seen that here is no ground-mounted equipment involved against which the athletes may be injured due to inattention.
  • Training equipment can conveniently include sensors for calculating speed or establish points of impact etc. as more fully explained below, but it is not a prerequisite.
  • Figure 2 shows the equipment shown in figure 1 seen from the side.
  • the line length can vary, but it is often appropriate to use a line of a length that makes the ball spend so much time for returning to the starting point that the athlete has time enough to reposition and prepare for a finishing attempt before the ball returns, which tends to require more than 5 meters of line, and typically 7-15 meters of line, without this being considered as any limitation of the invention.
  • the curved arrows in Figure 2 indicate that the direction of the extendable rod 11 is preferably adjustable vertically, i.e. the angle between the extendable rod (11) and the horizontal plane is adjustable.
  • the arrow labelled with the letter "L" indicates the length of the extendable rod also advantageously can be adjustable. It is significant that the line length and length of the rod are adapted to each other.
  • the rod length may be of the order of between 3 and 15 meters, more preferably between 6 and 11 meters and typically from 8 to 10 meters.
  • the free end of the rod, where the line leaves the rod, will typically be at a height of minimum 2.5 meters.
  • the line may be attached to the free end of the rod, but may desirably, as an alternative, be attached inside the pole, at or near the rod attachment, and run through the inside of the rod to the rod free end or outside of the rod, through line guides like on a fishing rod.
  • the free end of the rod typically protrudes up to 8 meters in the horizontal direction (L h ) over the pitch.
  • L h the horizontal direction
  • the active training area extends at least 16 meters out from goal. This provides good opportunities for training of passes as well as shots and finishing attempts with the head.
  • the line length in the stretched state should be longer than the rod length, but a maximum of about 2 meters longer. It is the overall, free line length referred to here, that is, the sum of the lengths of elastic and non-elastic parts of the line that connects the ball to the rod, but not including any portion of the line contained within the rod.
  • the relatively high attachment point for the line prevents the line from coming at rest on the ground when training actively with the ball.
  • the line will virtually all the time and in its entire length, soar over ground and not disturb the athletes.
  • the line When kicking or heading towards the goal, the line is sufficiently long to let the ball touch the net and show the point of impact, before the elastic portion of the line and the rod pulls the ball back out.
  • the adaptation of the line length to length of the rod a parameter of importance.
  • the elastic portion of the line 12 may be of limited length, for example of the order of half of the line length, but can also be longer or shorter than this. How much of the line being selected as elastic depends on the characteristics of the line, the characteristics of the rod, the weight of the ball used, etc. There is no need for a line that is able to cache all the kinetic energy of the ball, as also the rod is slightly elastic and will cache considerable amount of energy even at a modest curvature of the rod.
  • the dimensions will typically be smaller than the dimensions described above in connection with practice with a soccer ball, but still with the same considerations with regard to the interrelationship of rod length and line length.
  • the convenience of having a high attachment point for the line applies also here, both to ensure that the risk of athletes being injured by contact with the rod it is entirely ruled out, but also in order to keep the line suspended in the air under use.
  • the ball When shooting against a goal with a net, the ball will touch the net with the elastic part of the line already somewhat stretched, and the ball will therefore come back with speed and not come to rest in the goal.
  • the rod is somewhat elastic, not unlike a fishing rod, and will contribute to temporarily maintain the ball's kinetic energy when the ball turns and again regains this kinetic energy in the form of movement in substantially the opposite direction.
  • Figure 3 shows in further detail how the extendable rod 11 may be attached to a crossbar 15 which has the form of an extruded aluminium profile, with recesses at one side of the profile to receive fasteners for the goal net.
  • the extendable rod 11 is attached to a mounting bracket 31 which comprises an attachment plate 32 for attachment to the recess on the crossbar 15 backside.
  • the mounting bracket may comprise a vertically arranged, rotatable pin 33 which makes it possible to pivot the extendable rod 11 from one side to another. There will in case be a need for a locking device to prevent the extendable rod from pivoting every time it is affected by forces.
  • Figure 3 shows the mount assembly 31 comprising a rotating joint 32 which enables height adjustment of the extendable rod 11. Also this joint must naturally be lockable in desired position.
  • mounting bracket is only shown for attachment to a goal, it is understood that the functionality that allows different positions laterally and in respect of height can be included with any mounting bracket used for any application of the training equipment according to the present invention.
  • Figure 4 shows schematically that the extendable rod 11 can be attached with a special mounting bracket 41 to a wall 42.
  • the applications are essentially the same as for the embodiment shown in Figures 1 and 2, but naturally with somewhat less room for movement towards the wall compared to towards a goal. It is assumed not to use a wall that includes windows, doors or the like which can be damaged.
  • Figure 5 shows the equipment of the invention in the form of a rollable cart 51 with a framewo 52 to which one or more extendable rods of the present invention can be attached. Since such cart could represent a potential source of injury, it should be padded or protected behind a temporary fence 53 which is so designed that the risk of injury if running into the fence is minimal.
  • the fence comprises cones connected with a ribbon or string.
  • Figure 6 principally shows the same as figure 2, but in a variant in which the resilient part of the string 12 is not fixed directly to the ball, but spliced with a line part 12b with different
  • the line portion 12b preferably being attached the ball 13 via a swivel which helps prevent twisting of the line.
  • the line 12 is composed of any number of different string parts, at least one of which is elastic, while other parts of the line does not have to be elastic.
  • the elastic part of the line is usually not attached directly to the ball, and may not even be visible, as it may be located within the rod, attached to the pole, at or near the rod attachment.
  • the line part 12b which attaches to the ball 13 will typically be thin, light and not very elastic.
  • the purpose of using a line which is thin and light closest to the ball is to disturb the athlete as little as possible, both in relation to the tactile contact with the ball as the aesthetics.
  • figure 7 shows in principle the same as figure 2, but in an embodiment in which a sensor 71 is arranged at the outer end of the extendable rod 11.
  • a sensor 72 is arranged in the ball 13 and one or more sensors 73 are arranged in the goal.
  • the sensors can register in different ways and by means of per se known technology, direction and speed of the ball at all times and likewise optionally point of impact in the goal.
  • the sensors 71, 72 and 73 are arranged to communicate wirelessly, directly or indirectly, to a device 74 for computing, which can be localized at the training field or somewhere else entirely. The detailed operation of sensors and communication from these are not part of the present invention and therefore not described in further detail here.
  • sensors may be used, and the term sensors shall here be interpreted broadly.
  • sensors within the framework of “sensors” as used herein is also the use of high-speed cameras, such as of the type used in the sport of tennis term “hawkeye".
  • the overall purpose of the sensors is to register at least one parameter selected from the ball's position, velocity, rotation and point of impact, but preferably several of these simultaneously and in near real time.
  • the sensors typically can belong to one or more of the following groups of sensors: optical sensors, acoustic sensors, radio transmitters and wireless TLS (Real Time Location System)) tags.
  • Figures 8A-E illustrate a principle suitable for attachment between the ball 13 and the line 12.

  • the elastic line 12 is fixed to a freely rotatable swivel joint 83 in which a central part 83a is rotatable relative to a peripheral part 83 b.
  • Figure 8A also shows a cover plate 81 which extends around and closely adjacent the wire 12 where this protrudes from the ball.
  • the swivel joint 83 may have a cross-section as shown in Figure 8B with a substantially cylindrical central portion 83a and two extending arms 83b. Fully assembled and with inflated ball, the two arms 83b will lie in the recess 82b and the ball's bladder (not shown) will support the swivel joint 83 from below.
  • Figure 8C shows the support plate 82 from above with through opening 82a which fits the swivel joint 83 and to non-penetrating recess 82b at the support plate's downside, allowing the swivel joint to be rotated to a position where it no longer can be pulled out of the ball.

  • a difference between the support plate according to Figure 9A in comparison with that shown in Figure 8A is the through- opening which in Figure 9A has a first or outer portion which is generally cylindrical and a second or inner portion that is generally conical.
  • the cross-section of the through opening in the support plate 92 is circular and not large enough to allow the swivel joint to move therethrough regardless of its orientation.
  • the swivel joint 93 shown in Figure 9C comprises a cylindrical portion and a portion having the shape of a truncated cone. The two parts are preferably machined or molded in one piece and has a smooth surface to be rotatable in relation to the support plate 92.
  • the variant of the swivel joint shown in Figure 9D is given the designation 93 'and is outwardly similar to the swivel joint in Figure 9C.
  • the difference lays in that the swivel joint 93 'comprises an inner cylinder which is rotatable in the outer cylindrical portion of the swivel joint, which enables lower resistance to rotation.
  • Both variants shown in Figure 9 assume that the support plate 92 is removed if one is to replace the swivel joint or attaching a new line thereto.
  • the operation in the mounted state is, however, for all practical purposes the same as for the embodiment of Figures 8A-E.
  • Figure 10 shows a further possible aspect of the present invention, an element that can generally be described as an unpredictability mechanism.
  • the purpose of possibly including such an element would be to make it more difficult to predict exactly where the ball is coming back, e.g. as a simulation of a ball pass that changes direction by touching another player near by.
  • this is visualized by a rotatable disc 101 at the outer end of the extendable rod, through which the elastic line 12 is passed.
  • the rotatable disc will from an upright, neutral position, swing into the ball's direction when the ball is given a strike in one direction or another. As a result of gravity the plate will swing back when the line is no longer as tight.
  • the disc thus represents an eccentric- mechanism that can change the ball direction somewhat when it swings back.
  • Figure 10 furthermore shows a device 102 which is arranged to temporarily store parts of the energy supplied to the ball when it is given a strike, visualized as a single coil spring. It is however possible to use other means for storing kinetic energy for later release, and it is possible to combine this with a mechanical or electronically controlled delay which can give the ball changed speed at a time that can not be predicted.
  • the effect of eccentric mechanism as described and the effect of a device for storage and release of kinetic energy may be collectively referred to as an unpredictability mechanism.
  • This is not a mandatory feature of the present invention but may contribute to make the training more varied and more realistic than if omitting these elements. It goes without saying that the two indicated elements of unpredictability can be used separately or simultaneously. If higher flexibility in this mechanism is desired, use of electronic control systems and external energy supplied to the unpredictability mechanism can be applied.
  • the basic, fundamental features of the equipment are described above. It is understood that this equipment is well suited for combination with sensors for recording various qualities that athletes demonstrate during in use, such as the ability to give the ball a desired direction and desired speed.
  • the equipment can be combined with any such types of equipment, as possibly underlying computer devices that can calculate and keep track of the scores obtained, comparing with previous results etc., and presenting the results on mobile communication devices in the form of, for example, using so-called apps.
  • use of the equipment of the present invention in such a context may allow an athlete to monitor his or hers skill development over time; it will be possible to arrange competitions between participants locally, and it will even, by means of modern communications technology, be possible to arrange competitions where different athletes are geographically separated.

Abstract

Équipement permettant de s'entraîner avec un ballon (13), qui comporte une corde élastique (12) reliant le ballon (13) à un point d'ancrage fixe, le point d'ancrage fixe étant une perche extensible (11) conçue pour être fixée sur une structure existante, à une certaine distance au-dessus du niveau du sol, telle que la barre transversale d'un but. La perche (11) ainsi que la corde élastique (12) contribuent au stockage intermédiaire d'énergie lorsque le mouvement du ballon change de direction. Ledit équipement peut être combiné à des capteurs et à un équipement de communication électronique permettant une évaluation objective de la qualité des exercices effectués et offrant la possibilité de garder une trace de scores obtenus dans des matchs ou compétitions.
