Embodiment

Fig. 1 shows the bar 11 for the adjustable length being fixed on the cross bar at goal 14.At least part elastic threads 12 are attached The outer end of bar 11 is connected to, the rope 12 is correspondingly attached to ball 13.Rope 12 need not be uniform over the whole length, and need not Whole rope is elastic.It is light and thin as much as possible and can not have bright for example, also allow for the outside of rope near ball Aobvious elasticity.The bar of the adjustable length is typically telescopic, but can also have the shape for being tightened to separate part together Formula, if it is desired to small size obtain high intensity so this can be more easily.Although bar 11 is illustrated as in cross bar 15 Woodwork 14 is attached near portion, but it is also possible to be attached at close to the position of vertical pillars.Arrow is marked with " L " respectively.In Fig. 1 " R " show that the bar of adjustable length can be advantageously employed retention mechanism and be attached, the retention mechanism allow bar 11 with different from 90 degree pivot relative to the angle of goal line and are locked in this position.Fig. 1 may also provide the length of bar 11（L_h） Horizontal component instruction, the horizontal component can be such as 8-10 meters.

It should be appreciated that can be used for penetrating ball before goal in similar set ball here, but also it is used to pass With subsequent free kick because assuming that side line direction on play football will cause ball return, low or height, so as to avoid ball or Any position with body can be attempted by not avoiding the sportsman of ball（Including head）Ball is directed in goal.Here it can also hold Change places see can be injured because of carelessness without result in sportsman relevant floor-mounted apparatus.

Training device can easily include for calculating speed or determine the sensor of the point of impingement etc., such as more fully below Explanation, but this is not prerequisite.

Fig. 2 shows the device shown in the Fig. 1 seen from side.Here, adjustable length can be best understood from How bar can be configured so that the bar extends between goal and bottom line.Rope length degree can change, but often suitably use So that ball returns to starting point with many times so that there is sportsman time enough to come to reposition simultaneously in ball return Prepare the rope of length gone for goal shot, this generally requires restricting more than 5 meters, usual 7-15 meters rope, and this is not considered as Any limitation of the invention.Curved arrow in Fig. 2, which shows that the direction of bar 11 is preferably, to be vertically adjusted, i.e. Bar（11）Angle between horizontal plane is adjustable.In addition, can also with the length of the arrow indication rod of alphabetical " L " mark It is advantageously adjustable.

Importantly, the length of rope and the length of bar are adapted to each other.When for football（Association football）During training, such as Fig. 1 Shown in Fig. 2, the length of bar can be about between 3 and 15 meters, more preferably between 6 meters and 11 meters, be usually 8 to 10 meters.The free end of bar（Wherein rope leaves bar）Generally will be in minimum 2.5 meters height.Rope could attach to the free end of bar, But the inside of the rod member can be ideally attached at as a replacement, is attached at or near bar annex, and by bar Inside is extended to bar free end or by rope guider（Similar to fishing rod）And it is extended to the outside of bar.

For bar prominent slightly upward, although the appropriate inclination angle in side in the horizontal plane, but the freedom of bar The usual top in place in end is in the horizontal direction（L_h）Upper protrusion is up to 8 meters.It is at for the rope length degree of extended state, at least Grown as pole length, but not long a lot, such as 9 meters bars are 9.11 meters, effective training center stretches out at least 16 from goal Rice.This provides good chance for the training for passing and shooting and being scored with head.More generally, the rope length in extended state Degree should be longer than pole length, but maximum grows about 2 meters.Here mentioned total free rope length degree refers to ball being connected to The summation of the elastic portion of the rope of bar and the length in non-resilient portion, but not including any part for the rope being contained in inside bar.

Of a relatively high attachment point for rope prevents that rope is reached and rested on when being energetically trained using ball On ground.Rope will be crossed actually all the time and on the ground and not disturbed motion member over the entire length thereof.Played football when towards goal Or heading when, rope fully grow so as to conceded points before the elastic portion and bar of rope reversely release ball contact net and show fall Point.For the training using the bar for being attached to goal, it is important rope length degree is adapted to pole length.In addition, being rotated simultaneously in ball It is again introduced into before training place, the shooting for not striking against goal simply continues to the vertical plane passed through above cross bar at goal line most At big several meters, if shooting is being passed over.In this case, various experiments prove that ball almost returns to place all the time And it is not limited to the rear portion at goal.

Rope 12 elastic portion can have limited length, for example rope length degree is only about half of, but it is also possible to than this it is longer or It is shorter.Elect the rope of how much length as the elastic characteristic for depending on rope, the characteristic of bar, the weight for using ball etc..Without energy The rope of whole kinetic energy of ball is enough stored, bar is slightly elastic and will store substantial amounts of energy in addition, or even in the appropriate of bar Under curvature.

For the training of the handball before handball goal, size will typically be less than above for the training using football Described size, but still there is identical to consider in the correlation of pole length and rope length degree.With for rope The convenience of high attachment point is also applied for ensuring herein sportsman due to being contacted with bar and injured danger is fully arranged Remove, but hung in atmosphere also in a situation of use rope is maintained at.

When being shot towards the goal with net, the elastic portion of contact net and rope has somewhat been elongated by ball, therefore ball will Returned and do not stayed in goal with certain speed finally.As described above, bar is also somewhat flexible different from fishing rod, And it will be helpful to work as the kinetic energy that ball rotation makes temporarily to maintain ball, and it is extensive again when generally opposite side is run up This multiple kinetic energy.

In the case where special-purpose will not be confined to according to the training device of the present invention, it is clear that the training device is fitted very much Gone for goal shot together in training, i.e., shot or head shot towards goal with the ball in being kept in motion.If by its own directly The lower section of the free end of bar is positioned at, then penetrates how the direction of ball can all ensure to return to ball.Can be towards corner flag direction Bat to receive the ball of return, such as corner-kick.Can in outward direction be batted with ground on the scene and when be connected to come from after The pass in face returns to ball（When in face of goal）.Ball is promptly returned all the time.No matter individually or with other people practise, this It is very effective that the mode of kind, which is trained,.

Although ball can return to all the time, it is not returned to it by the identical position of impact position.This can occur Under exceptional circumstances, for example when from the location directly below square stance in bar free end or when cause ball directly bar from The square stance on the direction that the lower section held passes through.In other cases, ball by return to below bar free end generally in Circular region and with inaccuracy, the incorrectness depends on a number of factors, characteristic, the surface imperfection of such as device The direction of ball especially before last time is batted（Free end relative to bar is seen）.Because can not predict accurate Reentry point, so obtaining probabilistic another key element, which reflects the person's character of ball game, thus have more training The sense of reality, more efficient, more challenge and with more enjoyment.

Fig. 3 shows in more detail how the bar 11 of adjustable length can be attached into cross bar 15, and the cross bar 15 has aluminium The cross sectional shape of section bar, the side of cross sectional shape is provided with groove, and groove is used to assemble the fastener to fixed net.It is adjustable The bar 11 of length is attached in mounting bracket 31, and the mounting bracket 31 includes attachment plate 32, and the attachment plate 32 is attached in cross bar On the groove of 15 dorsal parts.In addition, mounting bracket may include vertically disposed rotatable pin 33, the pin enables bar 11 from side pivot Go to opposite side.There will be needs for locking device in some cases, to prevent bar from being pivoted whenever the effect by power.

In addition, Fig. 3, which is shown, includes the mounting assembly of rotary connector 34（Mounting bracket 31）, the connector 34 makes adjustable The height adjustment for saving the bar 11 of length is possibly realized.In addition, the connector can must naturally be locked in desired position.

Although mounting bracket is only illustrated for being attached to goal, but it is to be understood that allowing have different lateral positions Any mounting bracket of any purposes for the training device according to the present invention can be included in the function of height and position In.

Fig. 4 schematically shows the bar for the adjustable length that can be attached to wall 42 using special mounting bracket 41 11.These applications are generally identicals for the embodiment shown in Fig. 1 and Fig. 2, but have naturally with towards goal Motion be used for the space towards wall compared to somewhat less.Assuming that without using the window including that can be damaged, door etc. Wall.

Fig. 5 shows apparatus of the present invention of the form using the rollable trolley 51 with framework 52, of the invention one The bar of individual or multiple adjustable lengths can be attached to the framework 52.Because this trolley can represent potential injury source, So should will add protection pad to the trolley or be protected in behind temporary fence 53, the temporary fence 53 is designed to make If obtained into fence, injured danger is minimum.For example, the fence includes the cone being connected with strip or cord.

Fig. 6 mainly show with Fig. 2 identical situations, but the elastic portion of cord 12 is not directly fixed to wherein In one modification of ball, one section of rope 12b splicing with the characteristic with the other parts different from rope 12, this section rope 12b is excellent Selection of land is attached to ball 13 via swivel joint, and the swivel joint helps to prevent the torsion of rope.In principle, rope 12 is by any The different cord portions of quantity are constituted, and at least one cord portion therein is elastic, while the other parts of rope need not be bullet Property.The elastic portion of rope is generally indirectly attached to ball, and even can not be it is visible because it can be located at bar in Portion, it is attached to rod member, at bar annex or near it.

It generally will be thin, light and not very flexible to be attached to one section of rope 12b of ball 13.Using near ball The purpose of thin and light rope be disturbed motion person as few as possible, both of which is the tactile with ball as aesthetics.

In addition, Fig. 7 show in principle with Fig. 2 be identical situation, but wherein sensor 71 be arranged on it is adjustable In one embodiment of the outer end of the bar 11 of length.Sensor 72 is arranged in ball 13, and by one or more sensors 73 are arranged in goal.These sensors can utilize direction originally as known technical notes ball and speed in a different manner The degree all the time and similarly drop point optionally in goal.Sensor 71,72 and 73 be arranged to either directly or indirectly with dress 74 carry out radio communications are put to be calculated, the device 74 can be located at training place or entirely different place.Sensor Detailed operation and communication from these sensors be not the part of the present invention, therefore do not retouched in more detail here State.

The sensor of many types can be used, term " sensor " here shall be interpreted broadly.For example, high-speed camera The use of machine be also herein used in the range of " sensor ", such as term " the hawk used in tennis operation The type of eye ".The overall purposes of these sensors be simultaneously and by be almost in real time in the way of to the position selected from ball, speed At least one parameter in degree, rotation and drop point is recorded, but preferably some parameters in these parameters are recorded.

In addition, sensor generally may belong to one or more of sensor of following group：Optical sensor, sound are passed Sensor, transmitting set and wireless RTLS（Real-time positioning system））Label.
