Description

Volleyball training apparatus

The invention relates to a volleyball training apparatus, with a fastening unit for fastening the apparatus to a net post of a volleyball net, with a ball ramp fastened to the fastening unit for forming a ball queue from a plurality of volleyballs, with a ball catch basket arranged at a first end of the ball ramp for collecting and for reloading volleyballs into the ball queue and with one arranged at the opposite second end of the ball ramp

Ball holder for automatic reloading of volleyballs from the

Ball queue and holding a volleyball to train a volleyball attack shot.

Both the passing and the attack stroke are an essential element in the

Volleyball. A constant, exact pass to a certain position is that

Basis for a successful attack strike. The continuous improvement of both techniques is an important part of the training. Various devices are known in the trade for training the pass to a specific position. First and foremost, these are ball baskets that serve the target as a target. A ring with a net is attached to a stand and can be positioned anywhere on the field. The product "Volleyball feed ring" in the assortment of the company Ballsportdirekt.de (www.volleyballdirekt.de) is to be mentioned here. The disadvantage of these products is their use in beach volleyball. The stand must be securely attached to sand to prevent it from tipping over. There are also systems that serve to improve the attack strike. Carrying out an attack is a complex process, the success of which depends on various factors (assessment of the flight curve and distance, starting step, arm swing, jumping technique, stroke movement, etc.). To learn this technique, it can make sense to break the movement down into sub-steps and train them in isolation. Ultimately, however, it is necessary to train the entire movement sequence as closely as possible in order to coordinate all aspects better and to achieve an improvement in the game. Various systems are already known from the prior art which support the training of the attack strike. In the following, these are summarized according to how they work and the differences from them

Invention described.

Fixed volleyball systems with an elastic band or bar are known. Systems are currently on the market that hold a volleyball in the air with an elastic band or a stick. The MVA 300 ATTR from the manufacturer Mikasa, the patent specification CN 202497681 U and the

Patent US 5,238,251 A called. The attack blow can always with the same ball, since the band or the rod brings it back to the starting position. A disadvantage of these systems is the lack of feedback for the

Exercisers where and how volleyball would touch the ground. Another disadvantage is that the ball cannot be integrated into a game form after the attack. Another disadvantage is the attachment of these systems. In the sand on a beach volleyball court, these devices can easily tip over or not be installed at all.

Furthermore, devices in the form of simple ball holders are known in the prior art. A volleyball is clamped between two points and, with the help of a stick, the ball is held at a certain height for an attacker. The products "Ball holder" in the company's range are representative of this category

Ballsportdirekt.de (see www.volleyballdirekt.de) and the product "Volleyball Training Aid - SmartSpike" available at www.ebay.com. The disadvantage of these products is that after the attack hit the ball has to be manually pinched again and kept at a certain height. This takes time and disrupts the training flow for larger groups. Independent training is also not possible because a second person must hold the device.

In the prior art there are also systems with ball holder and automatic

Reload function known. With these devices, a volleyball is pinched and a new ball is automatically placed in the holder after an attack. The patent US 2014/0135152 A1 should be mentioned here, where the apparatus mentioned there is attached to a basketball hoop. The disadvantage of this system is that for the

Use of a basketball hoop or a similar holder is necessary. On one

Volleyball court in the hall or on the beach court does not meet this requirement. This means that training close to the game on the field (running paths, estimating distances, etc.) cannot take place.

Another system is known from US Pat. No. 2012/0165134 A1 and US Pat. No. 8,371,964 B2. This system includes an automatic ball reload function on its own stand with rollers, on which the device is mounted. The disadvantage of this system is the size and weight for use in beach volleyball. This device is designed for movement on firm, horizontal ground. At the beach volleyball court on sand, this device is cumbersome and must be aligned horizontally.

A ball catching mechanism is present in the systems mentioned above, but the opening of the collecting basket is only directed upwards and is used primarily for easy catching of the balls in the loading device. Hence the two

systems for the additional training of the pass only partially and limited suitability. Another disadvantage of the products mentioned above is the large difference in height between the ball catching mechanism and the ball holder.

Further volleyball training devices are known from FR 2722417 A1, US 5,913,739 A, US 7,041, 016 B1 and KR 101647118 B1. In the systems disclosed, however, the flexibility of the training is limited because only one attack stroke can be trained. In addition, some systems cannot train real game situations because the ball is not released.

Starting from the prior art, it is therefore an object of the invention to provide a

Combined device for training the pass and the attack on both a volleyball and a beach volleyball court.

According to the invention the object is achieved in that the ball catcher and the

Holding device are releasably attached to the ball ramp, the ball catcher for

Training a volleyball pass can be attached to the second end of the ball ramp instead of the ball holding device. The invention thus creates a system for learning, improving and analyzing the attack stroke and the precise passing of a ball. Net posts are always present in both indoor volleyball and beach volleyball, and their height and distance from the field are internationally standardized. The attachment to one of the two firmly anchored net posts eliminates the disadvantage of the poor stability of previous systems that were not or only poorly suited for beach volleyball. The ball holding device has the advantage that the ball can move freely after the attack and can thus be integrated into the game. By automatically reloading a ball from the ball queue into the

Ball holding device is no longer necessary to manually reload a single ball. An additional person is therefore not necessary.

The fastening unit preferably has a lifting and lowering mechanism for height adjustment of the apparatus. This allows the height of the apparatus to be adjusted individually, e.g. can be adapted to different groups of people, such as men, women and children.

The ball ramp is preferably detachably connected to the fastening unit, the ball ramp being pivotable relative to the fastening unit. This allows the distance to the playing field and the angle between the apparatus and the volleyball net to be set, which means that different positions for the passing and the attacking stroke can be trained.

The ball ramp is preferably in different angular positions relative to the

Fixing unit can be fixed so that the position of the device does not change during training. It is advantageous if a length can be set between the first end and the second end of the ball ramp, preferably by means of at least one telescopic tube. As a result, the ball holding device or the ball catcher can be used very flexibly in a larger area of the volleyball field.

The second end of the ball ramp is advantageously rotatable with a first one

Carrying element end of a support element connected and the support element is rotatably attachable to the fastening unit with an opposite second support element end, wherein the length of the support element is preferably adjustable. This allows the ball ramp to be positioned more flexibly relative to the volleyball net.

The ball ramp or the support element preferably have a device arm which extends in the transverse direction, the ball ramp or the support element having a first end or an opposite second end of the device arm on the

Fastening unit can be attached. This makes the device more flexible for both

Halves of the Voleyball field can be used.

The ball catcher basket preferably has a basket with a first opening and a second opening, the ball catcher basket being attachable to the first end of the ball ramp in such a way that volleyball can be fed to the basket through the first opening and through the second opening of the ball queue or directly to the ball holding device can be fed and can be attached to the second end of the ball ramp in such a way that a volleyball can be fed to the basket through the first opening by means of a pass.

The basket preferably has a net or a tube made of a closed, preferably textile material, wherein the tube can be attached to the ball holding device with the second opening for training the attack blow. The net or flexible hose reduces the risk of balls falling off the device and the weight of the device is kept as low as possible.

The ball catcher basket preferably has a joint for setting an angle between the ball catcher basket and the ball ramp. This allows the orientation of the basket to be varied for training the feed.

The ball holding device preferably has a frame for fastening the

Ball holder on the ball ramp, one rotatably attached to the frame

Trigger mechanism for automatically reloading balls from the ball queue into the ball holding device, a first connected to the trigger mechanism

Support surface and a second support surface connected to the frame, wherein the first and second support surface are designed to cooperate to hold a volleyball. This makes it simple and easy to use

Ball holding device created, which allows that after performing a Attack hit individual balls from the ball queue sequentially between the

Support areas can be reloaded.

A flexible tape, preferably a measuring tape, can preferably be arranged at the first and / or at the second end of the ball ramp. The tape can be used to attach the ball ramp to the volleyball net to stabilize the ball ramp when the ball ramp is not fixable relative to the mounting unit. If the tape is designed as a measuring tape, the height of the apparatus above the net edge or a jump height can be measured, for example.

A block module can preferably be provided in the apparatus, which can be attached to the inner end of the ball ramp instead of the ball holding device for training a volleyball block. In addition to the attack stroke and the passing, another important turn can be trained. It can be advantageous if the block module has a plate with markings for reading a block height above the net edge of the volleyball net.

The ball catcher and the ball holding device are preferably attachable to the ball ramp in a compact state for storing and transporting the apparatus, the ball catcher being fastened to the first end of the ball ramp and the ball holding device to the second end of the ball ramp such that the ball catcher and the ball holding device are in contact with one another are arranged facing the first and second ends of the ball ramp and touch each other. Some clubs train in separate halls and face the challenge of having to transport training equipment between these locations. A mobile and compact training device for use at different locations can save costs. The device can be folded up compactly and is therefore particularly well suited for transport.

Fig. 1 shows the floor plan of a volleyball court. The volleyball court is 18m long and 9m wide and is bordered by two base lines 7 and two side lines 8. In the middle, the volleyball field is separated by a volleyball net 9 and a center line in two halves of the game, each 9x9m. The volleyball net 9 is fastened and tensioned to two firmly anchored net posts 10A, 10B, which are located outside the volleyball field. According to international volleyball rules (see www.fivb.org), the distance 11 between net posts 10A, 10B and side line 8 must be between 0.50m and 1.00m. An antenna 12A, 12B is attached to the volleyball net 9 above each side line 8

Limitation of the sideline 8 on and above the volleyball net 9 indicates.

For better understanding, each half of the game is divided into six zones 1, 2, 3, 4, 5, 6, which usually indicates the position of the players. Both halves of the game are separated by a line of attack 13 at a distance of 3 m from the center line. This line of attack 13 divides a half of the game into a front zone 2, 3, 4 and a rear zone 1, 5, 6. A player training can be carried out with this apparatus from any zone 1, 2, 3, 4, 5, 6. Simple passes to the sideline 2, 4, which are played in front of or above the head, are basic techniques that every player must train. Both fast passes at first tempo and normal passes at second tempo can be trained. The pass can be trained parallel to the volleyball net 9 or at a certain angle. An attack strike is possible with this device in position 2 and position 4. These are two basic positions for learning the

Attack blow.

It is not possible to train the strike from the back room 5, 6, 1 or a jump service from baseline 7. This is not absolutely necessary for learning, improving and analyzing the technique, as all essential elements in the front room can be trained in position 2 and position 4. There is no center line or line of attack in beach volleyball. The volleyball court is 16m long and 8m wide. According to the international beach volleyball rules (see www.fivb.org) the

Net posts 10A, 10B are between 0.70m and 1.00m outside the side lines 8. In FIVB, World and Official competitions, the network posts 10A, 10B must be located at a distance of 1.00m outside the side lines 8. In indoor volleyball as well as in beach volleyball, the net posts 10A, 10B are 2.55 m high. FIG. 2 shows a top view of a volleyball court with two apparatuses according to the invention fastened to the net posts 10A, 10B. The length 14 of the apparatus can be adjusted with the aid of telescopic tubes. Training of attack strikes 15 along the

Side line 8 is possible. The angle 16 to the volleyball net 9 can also be changed and is used for training diagonal attacks 17 in the opposing field. The training of the pass can be trained from any position 1, 2, 3, 4, 5, 6.

3 shows a side view of two apparatuses attached to the net posts 10A, 10B parallel to the volleyball net 9. The apparatus is mounted on the left net post 10A with the aid of a fastening unit 18 and is ready for training the attack blow. The ball catch basket 19 is located at the outer end of a ball ramp 20 and is used for the

Collection and reloading 21 of the balls used in the ball queue 22. A

Ball holding device 23 holds a ball in the air and automatically reloads balls from ball queue 22. The apparatus for training the feeder 21 is attached to the right network post 10B. The ball catch basket 19 is mounted at the inner end of the ball ramp 20 instead of the ball holding device 23. The height 24 of the apparatus can be adjusted individually and enables training for both children and adults.

Fig. 4 shows a side view of the fastening unit 18 in the attached state on

Net post 10A. A C-profile 25 is attached with the open side outward on the outside of the net post 10A and contains the lifting and lowering mechanism for the apparatus. For better adhesion of the fastening unit 18 to the net post 10A there is a rubber pad 26 between the C-profile 25 and the net post 10A. Inside the C-profile 25 there is a T-profile 27 which can be moved vertically by means of a loop rope 28 . The C-profile 25 is open at both ends and allows the T-profile 27 to be pulled out both downwards and upwards. At the top of the

Fastening unit 18 is a deflection mechanism 29 for the loop rope 28 and a projection 30A, 30B which rests on the top of the net post 10A and transfers the entire weight of the apparatus to the net post 10A. So that the apparatus cannot tip over or slide sideways, two tensioning belts 31A, 32A and screw terminals 33A, 33B fix the C-profile 25 to the net post 10A. At the upper end of the T-profile 27 there is a pin 34 and a bearing surface 35 for the assembly of the apparatus. A scale 36 on the T-profile 27 shows the current lay height. Some net post models have a wheel 37 on top to tension the volleyball net 9.

5 shows a top view of the fastening unit 18 on a rectangular net post 10. Although the height of net posts is standardized to 2.55 m, their width and shape are not. The mounting unit 18 must cover a wide range of existing models. The base of a net post 10 usually has a rectangular or round shape. At the upper end of the C-profile 25 is the deflection mechanism 29 for raising and lowering the T-profile 27. A projection 30A, 30B of the fastening unit 18 rests on the net post 10 and transfers the entire weight of the apparatus onto the net post 10. Am At the end of the T-profile 27 there is a pin 34 and one

Support surface 35 with openings 38. These openings 38 contain a thread and serve to fix the apparatus at a certain angle 16 (see FIG. 2) to the volleyball net 9. On the sides of the C-profile 25 there are two screw clamps 33A, 33B for the lateral fixation on the net post 10. The tension belt 31A is tensioned around the net post 10 and secured with the tensioning device 31 B in order to release and tilt the

Prevent mounting unit 18.

6 shows a front view of the lower part of the fastening unit 18. The tensioning belt 32A and the tensioning device 32B are located on the sides of the C-profile 25. The lower end of the C-profile 25 is open so that the T-profile 27 can slide down to a certain point. One end of the loop rope 28 is attached to the T-profile 27 and the other end to a carabiner 39 on the outside of the C-profile 25. The assembly of the loop rope 28 in the lower third of the T-profile 27 controls the maximum extension of the T- Profile 27 upwards. The length of the loop rope 28 controls the maximum extension of the T-profile 27 downwards. The height 24 of the apparatus is regulated by pulling on the loop rope 28 and secured by hanging the loop rope 28 into the carabiner 39.

FIG. 7 shows a section through the fastening unit 18 according to section line A-A in FIG. 6. Within the C-profile 25, two square tubes 40A, 40B serve as sliding surfaces for the T-profile 27. The two tubes 40A, 40B are riveted to the rear of the C-profile 25. On the back of the C-profile 25, a rubber pad 26 ensures better adhesion of the fastening unit 18 to the net post 10. Between the square tubes 40A, 40B there is a gap in which a loop rope 28 can slide up and down. The

Loop cable 28 is fastened via a hole 41 in the T-profile 27 and by means of a cable clamp 42 on the outer part of the T-profile 27.

8 shows a rear view of the fastening unit 18 and the deflection mechanism. At the end of the C-profile 25, a deflection mechanism 29 for the loop rope 28 is attached.

Two square rods 43A, 43B on the deflection mechanism 29 have openings with a screw thread 44. These rods 43A, 43B are inserted into the square tubes 40A, 40B within the C-profile 25 and fastened with screws to the rear of the C-profile 25. The deflection mechanism 29 is wider than the C-profile 25 so that the loop rope 28 can slide past the outside of the C-profile 25. The support surface in the form of the projections 30A, 30B of the fastening unit 18 is also located on the deflection mechanism 29 Net post 10. A rubber strip 26 on the back of the C-profile 25 ensures better adhesion of the fastening unit 18 to the net post 10.

FIG. 9 shows a section through the deflection mechanism of the fastening unit 18 according to section line B-B in FIG. 8. A square tube forms a sheath 45 in which a rope pulley 46 is located. A countersunk screw and screw nut 47 rotatably fasten the cable pulley 46 to the sleeve 45. Two square bars 43A, 43B connect the sleeve 45 to the C-profile 25. The cable pulley can be mounted either over the left bar 43A or over the right bar 43B. On the outside of the sheath 45, two rods form a projection 30A, 30B and thus a contact surface of the fastening unit 18 on the net post 10. The sheath 45 is narrower than the C-profile 25 so that the T-profile 27 can slide past it.

10 shows a top view of the ball ramp 20. This part consists of a device arm 48, two telescopic tubes 49A, 49B, a pull-out 50 and a platform 51.

The frame is composed of a vertical part 74A and a horizontal part 74B, which are at an angle of 90 degrees are connected by means of two screws 80. Two gusset plates 81 A, 81 B give the horizontal frame 74B additional stability. On the vertical frame 74A there are two pins 82A, 82B which are inserted into both holes 57A, 57B of the pull-out 50 and connect the ball holding device 23 to the ball ramp 20. Holes 83 in these pins 82A, 82B are used for fixing with locking bolts 58A, 58B to the pull-out 50. The release mechanism 75 is rotatably attached to the lower end of the vertical frame 74A. At the end of the horizontal frame 74B there is a U-profile 84A with the opening inwards. In this U-section 84A, the second padded support surface 86 is pivotably mounted on a rod 85 with the aid of a screw 84B. This ball rest 86 can be folded inwards for the transport of the apparatus.

19 shows a rear view of the ball holding device 23. A cross strut 87 on the vertical frame 74A limits the height of the frame to the maximum height of a ball. The trigger mechanism 75 is for the automatic reloading of the balls into the

Ball holder 23 responsibly and rotatably attached to frame 74A. At the

The trigger mechanism 75 is located on the outside of two stoppers 77A, 77B, which abuts the frame 74A and prevents the bearing surface 79 from rotating completely downward.

20 shows a top view of the release mechanism 75 with the first support surface 79 of the ball holding device 23. This consists of a padded support surface 79 which is connected via two rods 78A, 78B, each with a counterweight 76A, 76B. The ball rolls over the extension 50 onto the support surface 79 via the two rods 78A, 78B. On both sides of the counterweight 76A, 76B there is a stopper 77A, 77B, which prevents the support surface 79 from sinking completely.

21 shows a side view of the release mechanism 75 with the first bearing surface of the ball holding device 23. At the transition between the counterweight 76 and the rods 78A, 78B there is a hole 88 for mounting on the vertical frame 74A of FIG

Ball holding device 23. 22 shows a side view of the second contact surface of the ball holding device 23. This consists of a rod 85 and a padded support 86. At the end of the rod 85 there is a hole 89 for mounting on the U-profile 84A of the ball holding device 23.

23 shows a rear view of the second support surface 86 of the ball holding device 23. The padded support surface 86 is narrower than a ball and is fastened to the rod 85 by means of screws 90.

24 shows a side view of the ball holding device 23 and describes the automatic reloading function of balls. Balls are internationally standardized with a circumference between 65cm and 67cm in indoor volleyball or between 66cm and 68cm in beach volleyball and a weight between 260g to 280g (see official volleyball and beach volleyball rules at www.fivb.org). The diameter between the balls therefore varies by a maximum of two centimeters. As long as no ball is clamped between the two support surfaces 79, 86, the counterweight 76A, 76B rests on the pull-out 50 of the ball ramp 20 and holds the first support surface 79 horizontally in the air. Rolling a ball between the pull-out 50 of the ball ramp and the cross strut 87 of the ball holding device is possible because the distance is larger than the diameter of a ball. After the ball has rolled onto the support surface 79, the counterweight 76A, 76B lifts and the support surface 79 lowers until both stoppers 77A, 77B on the vertical frame 74A of the

Ball holding device 23 stand in line. As a result, the ball is between the two contact surfaces 79,

86 pinched.

25 shows a side view of a pinched ball in the ball holding device 23 and describes the automatic lock for subsequent balls. If a ball is clamped between the two support surfaces 79, 86, the counterweight 76A, 76B is raised. A subsequent ball is raised by the rectangular shape and the distance between the two counterweights 76A, 76B. Rolling through between pull-out 50 and the cross strut

87 is not possible because the distance is smaller than the diameter of a ball. Only after the ball has been knocked out of the padded support surfaces 79, 86 does the counterweight 76A, 76B drop again and the next ball is released.

Fig. 26 shows a side view of the apparatus in the compact state. This variant of the assembly is intended for storage or transport. The telescopic tubes 49A, 49B of the ball ramp are set to the smallest possible distance and with the help of a

Locking bolt 56 fixed. The entire ball holding device 23 is rotated horizontally by 180 degrees and secured to the pull-out 50 with the aid of locking bolts 58A, 58B. Both support surfaces 79, 86 are folded up so that they rest on the telescopic tubes 49A, 49B. The ball catcher 19 is opening down onto the frame of the Ball holding device 23 placed. The pins 69A, 69B on the ball catch basket 19 are inserted into the holes 54A, 54B on the device arm 48 and secured with the aid of locking bolts 55A, 55B.

27 shows an alternative embodiment of the fastening unit 18 for fastening the apparatus to the net post 10. Starting from a tensioning device 91, a rope 92 runs through four eyelets 93A, 93B, 93C, 93D on the outside of a rail 94. This rope 92 forms the upper one At the end of the rail 94, a loop which can be placed around the net post 10. The other end of the rope 92 can be stretched around the net post 10 at the lower end of the rail 94 and fastened on the opposite side by means of the eyelet 93A. The tensioning device 91 tightens the rope 92 and fixes the rail 94 to the net post 10. The fastening unit 18 is in this

Embodiment around a roller-mounted rail system, which can be adjusted in height relative to the network post 10 via a pull cable 95. The device arm 48 can be arranged on the fastening unit 18 via a pin 96.

28 shows a side view of two apparatuses attached to the net posts 10A, 10B, parallel to the net. The apparatus for measuring the jump height is mounted on the left network post 10A. In this embodiment, the apparatus has a carrying element 99. The ball ramp 20 is rotatably connected with the second (here inner) end to a second (here inner) support element end. The opposite first (here outer)

The end of the support element is rotatably connected to the fastening unit 18. This enables a more flexible pivoting of the ball ramp 20 because the ball ramp 20 can be pivoted relative to the support element 99 and the support element 99 relative to the fastening unit 18. At the first (outer) end of the ball ramp 20, a flexible tape, here a measuring tape 97 is attached, which hangs down. The first (outer) end of ball ramp 20 is mounted here at a target height that a player should reach. The measuring tape 97 can be used to read how far a player is from the set target height when measuring the jump height. The measuring tape 97 could alternatively or additionally also be fastened to the second (inner) end of the ball ramp 20 in order to indicate how high the apparatus is above the net edge. The measuring tape 97 can be attached in a fixed or removable manner. The measuring tape 97 can also be used, for example

Teeing height for training the attack blow can be set when the

Ball holding device 23 is attached to the inner (second) end of ball ramp 20 or the height for training the pass when the ball catcher 19 is attached to the inner (second) end of ball ramp 20. A block module 98 is attached to the right net post 10B in FIG. 28 in place of the ball holding device 23 at the second end of the ball ramp 20 of the apparatus. The block module 98 has a plate that is substantially parallel to the

Volleyball net 9 is mounted over the net edge. The lower end of the plate is adjacent to the Edge of the net. Markings are arranged on the plate at which a player can read his block height above the volleyball net 9.

The tape or the measuring tape 97 can advantageously also be used to attach the ball ramp 20 to the volleyball net 9, so that pivoting of the ball ramp 20 during the training is prevented. Furthermore, the tape or measuring tape 97 can also be used as a pull line in order to set the angle 16 between the ball ramp 20 and the volleyball net 9 (see FIG. 2). This is particularly advantageous if the ball ramp 20 is arranged at a height above the floor at which it cannot be reached.

29 shows a side view of the ball ramp 20 with a carrying element 99, a ball catch basket 19 mounted on the first end of the ball ramp 20 and with a ball holding device 23 attached to the second end of the ball ramp 20 for training the attack blow.

The ball ramp 20 here has a telescopic tube 49A, through which a certain length of the ball ramp 20 can be adjusted. The ball ramp 20 can also have a fixed predetermined length for use in training and by means of the

Telescopic tube 49A can only be retracted into a compact state,

for example for transportation. Of course, e.g. two parallel telescopic tubes 49A, 49B can also be used to increase the stability of the ball ramp 20. The

Carrying element 99 also has a telescopic tube 99A here, two parallel telescopic tubes 99A, 99B again being conceivable here. By adjusting the length of the telescopic tube 99A, the distance between the ends of the support elements and thus the distance 14 (see FIG. 2) from the side line 8 can be set. At the left outer (first) end of the ball ramp 20, the ball catch basket 19 is inserted into the telescopic tube 49A and fixed therein. At the right inner (second) end of the ball ramp 20, the ball holding device 23 is fastened, here on the pull-out 50. As already mentioned, the ball ramp 20, here with the pull-out 50, is rotatably connected to the second (inner) support element end of the support element 99, as by the arrow in Fig. 29 is indicated. The free first end of the support element here can be rotatably arranged on the fastening unit 18, for example with the device arm 48 shown.

The ball catch basket 19 here again has a basket 64 and is connected to the ball ramp 20 via a joint 64A. The angle of the basket 64 relative to the ball ramp 20 can be adjusted by means of the joint 64A. The hinge 64A can advantageously be fixed in a set position. Setting a certain angle can be advantageous for training the pass, in which the ball catcher 19 is arranged at the second (inner) end of the ball ramp 20. Instead of a net 65 (see FIG. 16), the basket 64 here has a hose 65A made of a suitable flexible material, for example made of a textile material. The second opening of the basket 64 facing the ball holder 23 can be attached to the vertical frame 74A of the ball holder 23 four loops 100A, 100B, 100C, 100D. Alternatively, a flexible band (not shown) could also be provided. As a result, balls can roll through the first opening of the basket 64 (here on the left) within the hose 65A of the basket 64 along the ball ramp 20 and out of the second opening into the ball holding device 23. This can ensure that balls do not fall out of the ball queue 22 onto the floor while they are being fed to the ball holding device 23. Because the balls are guided within the tube 65A, it is also sufficient in this embodiment that the ball ramp 20 has only one telescopic tube 49A.

The trigger mechanism 75 has in the example shown instead of a first

Support surface 79 (see e.g. Fig. 20) on two first support surfaces 103A (see Fig. 30), whereby an improved hold of the volleyball is achieved. The distance 102 between the contact surfaces 103A, 86 of the ball holding device 23 is preferably adjustable, for example via a screw 101.

30 shows a front view of the ball holding device 23 of an alternative

Embodiment. Instead of a fixed cross strut 87 (see FIG. 19), the passage height 104 for balls can be adjusted using a screw 105. On the vertical frame 74A of the ball holding device 23 there are four fastening options 106A, 106B, 106C, 106D for mounting the basket 64 of the ball catcher basket 19, in particular the loops 100A, 100B, 100C, 100D of the hose (see FIG. 29). At the lower ends of the vertical frame 74A are two rotatable end pieces 107A, 107B. A rectangular cross section of the frame 74A and the corresponding openings 57A of the pull-out 50 (see FIG. 10) can prevent the ball holding device 23 from loosening from the ball ramp 20. For this purpose, the ends of the frame 74A can first be inserted through the openings 57A of the pull-out 50 and then the

End pieces 107A, 107B (below the pull-out 50) can be rotated relative to the vertical frame 74 and the openings 57 by an angle of, for example, 45 degrees. This system can of course also be used in an analogous manner to secure all other components of the apparatus.
