Definitions
- the invention relates to a baffle for a system for collecting tennis balls, at the foot of which a collecting channel for the balls is arranged, to which a ramp rising towards the playing field is connected, the baffle having a flexible covering which is fastened to a frame and the diagonally inclined covering of the baffle is only attached to the top and bottom of the frame.
- Such systems as they are known for example from DE-A-2456 997 have the purpose of collecting the balls hit by a player against the baffle or the ramp and feeding them to a conveyor device which transports them to a container. A ball throwing machine is then connected to this container.
- the covering of the baffle has turned out to be critical for the functioning of these devices, since a certain mixture of elasticity and damping must be achieved, which leads to the balls falling into the collecting trough with as little residual energy as possible and ultimately remaining in this.

- GB-A-1 223 579 also intercepts an impacting tennis ball in such a way that it is not thrown back into the field.
- a safety net is attached to side swivel arms, which allow the entire net to swing out when a ball hits it. This solution is associated with a larger, considerable space requirement and is also limited to vertical baffle walls.
- WO-A-80/01 650 shows loosely hanging webs of fabric which are intended to bring the impacting balls to approximately the same final speed, relatively independently of their initial speed, at which they bounce back from a rigid impact surface.
- the invention is intended to make it possible to create a baffle wall for which almost any covering can be used, which from the point of view of durability, cleanability, weather resistance, and the like. can be selected, and the balls hit against them fall into the collecting trough with as little residual energy as possible.
- each upright side part of the frame consists of two hingedly connected, under the action of a spring stretching the struts.
- the upper spar is articulated at the upper end of the lower spar and forms a two-armed lever
- the spring designed as a tension spring engages between the shorter lever arm and the lower spar, the end of the longer lever arm being the the covering on the top edge of the frame is arranged.
- This design allows a particularly simple construction, which can be changed in a simple manner in terms of the extent of damping and also in the inclination, in particular if the upper spar has several bearing points and both spars have several suspension options for the spring.
- an aspect ratio for the two lever arms of 1: 6 and an oblique inclination of the upper spar of approximately 50 ° to the vertical has proven to be favorable.
- the spring which keeps the covering tensioned is a compression spring, for example a gas spring of a known type, and it is possible to accommodate it in the interior of the lower bar.
- the invention allows some freedom in the choice of the covering material. Therefore, if the arrangement is to be set up outdoors, efforts will be made in particular to limit the wind pressure and, in this sense, to choose a net as the covering material.

Abstract
Description
Die Erfindung bezieht sich auf eine Prallwand für eine Anlage zum Sammeln von Tennisbällen, an deren Fuß eine Sammelrinne für die Bälle angeordnet ist, an die eine zum Spielfeld hin ansteigende Rampe anschließt, wobei die Prallwand eine flexible Bespannung aufweist, die an einem Rahmen befestigt ist und die schräg nach vorne geneigte Bespannung der Prallwand lediglich oben und unten am Rahmen befestigt ist.The invention relates to a baffle for a system for collecting tennis balls, at the foot of which a collecting channel for the balls is arranged, to which a ramp rising towards the playing field is connected, the baffle having a flexible covering which is fastened to a frame and the diagonally inclined covering of the baffle is only attached to the top and bottom of the frame.
Derartige Anlagen wie sie beispielsweise aus der DE-A-2456 997 bekannt sind haben den Zweck, die von einem Spieler gegen die Prallwand oder die Rampe geschlagenen Bälle zu sammeln und einer Fördereinrichtung zuzuführen, welche sie zu einem Behälter weitertransportiert. An diesen Behälter ist dann eine Ballwurfmaschine angeschlossen. Als kritisch für das Funktionieren dieser Einrichtungen hat sich die Bespannung der Prallwand herausgestellt, da eine bestimmte Mischung von Elastizität und Dämpfung erzielt werden muß, welche dazu führt, daß die Bälle mit möglichst geringer Restenergie in die Sammelrinne fallen und schließlich in dieser verbleiben. Gemäß der erwähnten DE-A-2 456 997 wird ein Netz oder Gitter lose durchhängend angeordnet und in mittlerer Höhe etwas nach hinten gezogen.Such systems as they are known for example from DE-A-2456 997 have the purpose of collecting the balls hit by a player against the baffle or the ramp and feeding them to a conveyor device which transports them to a container. A ball throwing machine is then connected to this container. The covering of the baffle has turned out to be critical for the functioning of these devices, since a certain mixture of elasticity and damping must be achieved, which leads to the balls falling into the collecting trough with as little residual energy as possible and ultimately remaining in this. According to the mentioned DE-A-2 456 997, a net or grid is arranged loosely sagging and pulled back slightly at a medium height.
In der DE-A-2 334 849 wird vorgeschlagen, Bahnen aus "elastisch dämpfendem" Material zu verwenden und diese unter Spannung zu setzen, wobei nähere Angaben darüber, welches Material diese Eigenschaften aufweisen soll, fehlen. Aus der US-A-2 280 376 ist bekannt geworden, vor der als Netz ausgebildeten Prallwand eine Reihe von schräg verlaufenden Netzen vorzusehen, welche die gegen die Wand gespielten Bälle am Zurückprallen hindern. Die Verwirklichung dieses Vorschlages ist allerdings eher aufwendig und die Haltbarkeit der Vielzahl verwendeter Netze ist zweifelhaft.In DE-A-2 334 849 it is proposed to use webs made of "elastically damping" material and to put them under tension, although there is no further information about which material should have these properties. From US-A-2 280 376 it is known to provide a series of inclined nets in front of the baffle designed as a net, which prevent the balls played against the wall from rebounding. However, the implementation of this proposal is rather complex and the durability of the large number of networks used is questionable.
Auch durch die GB-A-1 223 579 wird ein aufprallender Tennisball so abgefangen, daß er nicht ins Spielfeld zurückgeworfen wird. Zu diesem Zweck ist ein Auffangnetz an seitlichen Schwenkarmen befestigt, die ein Ausschwingen des gesamten Netzes bei Auftreffen eines Balles ermöglichen. Diese Lösung ist mit einem größeren, erheblichen Platzbedarf verbunden und zudem auf lotrechte Prallwände beschränkt.GB-A-1 223 579 also intercepts an impacting tennis ball in such a way that it is not thrown back into the field. For this purpose, a safety net is attached to side swivel arms, which allow the entire net to swing out when a ball hits it. This solution is associated with a larger, considerable space requirement and is also limited to vertical baffle walls.
Die WO-A-80/01 650 zeigt noch lose hängende Gewebsbahnen, die die auftreffenden Bälle relativ unabhängig von ihrer Anfangsgeschwindigkeit auf etwa dieselbe Endgeschwindigkeit bringen sollen, mit welcher sie von einer starren Prallfläche wieder zurückspringen.WO-A-80/01 650 shows loosely hanging webs of fabric which are intended to bring the impacting balls to approximately the same final speed, relatively independently of their initial speed, at which they bounce back from a rigid impact surface.
Schließlich sind auch Bespannungen bekannt geworden, die schräg nach vorne geneigt und lediglich oben und unten am Rahmen befestigt sind, (US-A-4 082 271 ) doch dienen diese dazu, die aufprallenden Bälle wieder ins Spielfeld zurückzuschleudern.Finally, covers have also become known which are inclined forward and only attached to the top and bottom of the frame (US-A-4 082 271), but these serve to throw the impacting balls back into the playing field.
Im Gegensatz zu den bekannten Einrichtungen soll es die Erfindung ermöglichen, eine Prallwand zu schaffen, für die eine nahezu beliebige Bespannung verwendet werden kann, die unter dem Gesichtspunkt der Strapazierfähigkeit, Reinigungsfähigkeit, Wetterfestigkeit, u.dgl. ausgewählt werden kann, und die gegen sie geschlagenen Bälle mit möglichst geringer Restenergie in die Sammelrinne fallen läßt.In contrast to the known devices, the invention is intended to make it possible to create a baffle wall for which almost any covering can be used, which from the point of view of durability, cleanability, weather resistance, and the like. can be selected, and the balls hit against them fall into the collecting trough with as little residual energy as possible.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß jeder aufrechte Seitenteil des Rahmens aus zwei gelenkig miteinander verbundenen, unter der Wirkung einer Feder die Bespannung streckenden Holmen besteht.According to the invention, this object is achieved in that each upright side part of the frame consists of two hingedly connected, under the action of a spring stretching the struts.
Da die Breite der Hallen, für welche die erfindungsgemäße Anlage verwendbar sein soll, in weiten Grenzen schwankt, ist es sinnvoll, die Prallwände in Teilstücken konstanter Länge herzustellen, die aneinandergereiht werden können.Since the width of the halls, for which the system according to the invention is to be used, fluctuates within wide limits, it makes sense to manufacture the baffle walls in sections of constant length that can be strung together.
Um hier keine Unterbrechung der bespannten Flächen durch die aufrechten Seitenteile zu erhalten, empfiehlt es sich, daß die Bespannung diese beidseitig überragt. Hierdurch wird verhindert, daß Bälle in diesen Bereichen ungedämpft ins Spielfeld zurückprallen.In order to prevent the upholstered surfaces from being interrupted here by the upright side parts, it is recommended that the covering protrude above them on both sides. This prevents balls in these areas from bouncing back into the field undamped.
In einer bevorzugten Ausführung der Erfindung ist vorgesehen, daß der obere Holm am oberen Ende des unteren Holmes angelenkt ist und einen zweiarmigen Hebel bildet, und die als Zugfeder ausgebildete Feder zwischen dem kürzeren Hebelarm und dem unteren Holm angreift, wobei am Ende des längeren Hebelarmes die die Bespannung oben haltende Randleiste des Rahmens angeordnet ist. Diese Ausführung erlaubt eine besonders einfache Konstruktion, die insbesondere, wenn der obere Holm mehrere Lagerstellen und beide Holme mehrere Einhängemöglichkeiten für die Feder aufweisen, in einfacher Weise im Dämpfungsausmaß und auch in der Neigung verändert werden kann. In Versuchen hat sich dabei ein Längenverhältnis für die beiden Hebelarme von 1 : 6 und eine Schrägneigung des oberen Holmes von ca. 50° zur Vertikalen als günstig erwiesen.In a preferred embodiment of the invention it is provided that the upper spar is articulated at the upper end of the lower spar and forms a two-armed lever, and the spring designed as a tension spring engages between the shorter lever arm and the lower spar, the end of the longer lever arm being the the covering on the top edge of the frame is arranged. This design allows a particularly simple construction, which can be changed in a simple manner in terms of the extent of damping and also in the inclination, in particular if the upper spar has several bearing points and both spars have several suspension options for the spring. In experiments, an aspect ratio for the two lever arms of 1: 6 and an oblique inclination of the upper spar of approximately 50 ° to the vertical has proven to be favorable.
Es ist auch möglich, den oberen Holm als einarmigen Hebel auszubilden, was zu einer sehr kompakten Bauweise der Einrichtung führt. Die Feder, welche die Bespannung gespannt hält, ist in diesem Falle eine Druckfeder, beispielsweise eine Gasfeder bekannter Bauart, und es ist möglich, sie im Inneren des unteren Holmes unterzubringen.It is also possible to design the upper spar as a one-armed lever, which leads to a very compact design of the device. In this case, the spring which keeps the covering tensioned is a compression spring, for example a gas spring of a known type, and it is possible to accommodate it in the interior of the lower bar.
Die Erfindung erlaubt einige Freiheit bei der Wahl des Bespannungsmaterials. Wenn die Anordnung daher im Freien aufgestellt werden soll, wird man insbesondere danach trachten, den Winddruck zu beschränken und in diesem Sinne ein Netz als Bespannungsmaterial wählen. Vorteilhafterweise ist vorgesehen, von der zwischen der oberen und unteren Randleiste des Rahmens verlaufenden Bespannung Streifen aus Bespannungsmaterial frei herabhängen zu lassen: mit geringer Wucht auftreffende Bälle werden in diesem Fall bereits von diesen Bahnen aufgefangen und nach unten abgelenkt Nur kräftiger geschlagene Bälle führen zu einer Ausbuchtung der Bespannung selbst und zu einer Veränderung des Winkels zwischen den Seitenholmen des Rahmens.The invention allows some freedom in the choice of the covering material. Therefore, if the arrangement is to be set up outdoors, efforts will be made in particular to limit the wind pressure and, in this sense, to choose a net as the covering material. Advantageously, it is provided that strips of covering material hang freely from the covering running between the upper and lower edge strips of the frame: in this case, balls hitting with little force are already removed from these paths caught and deflected downwards Balls hit harder lead to a bulging of the covering itself and to a change in the angle between the side rails of the frame.
Weitere Einzelheiten der Erfindung werden anschließend anhand der Zeichnung erläutert.

- Fig. 3 is a second embodiment of the connection of the upper and lower Holmin more illustrative
Die Prallwand nach Fig. 1 und 2 besteht im wesentlichen aus einer von Seitenteilen getragenen, nach vorne geneigten Bespannung 1. Die Bespannung verläuft zwischen oberen und unteren Randleisten 13, 12, die die Seitenteile vorzugsweise geringfügig überragen. Am Fuß der Bespannung 1 ist eine Sammelrinne 3 angeordnet, durch die die Tennisbälle - im Ausführungsbeispiel mittels einer Förderschnecke 15 - abtransportiert und anschließend einer Ballwurfmaschine zugeführt werden.The baffle according to FIGS. 1 and 2 essentially consists of a covering 1 carried by side parts and inclined towards the front. The covering runs between upper and
Jeder Seitenteil setzt sich aus zwei Holmen 4, 5 zusammen, die über ein Gelenk 8 verbunden sind. Jeder untere Holm 4 steht dabei vertikal in einem Fußgestell 14, das auch die Sammelrinne 3 trägt und an dem die nur angedeutete Rampe 2 mit ihrem abfallenden Bereich hochschwenkbar angeordnet ist.Each side part is composed of two
Das Gelenk 8 ist am oberen Ende des unteren Holmes 4 vorgesehen und lagert den einen zweiarmigen Hebel bildenden oberen Holm 5, wobei der längere Hebelarm 5" etwa die sechsfache Länge des kürzeren Hebelarmes 5' aufweist. Das freie Ende des längeren Hebelarmes 5" trägt die obere Randleiste 13 der Bespannung 1 und am freien Endbereich des kürzeren Hebelarmes 5' greift eine Zugfeder 10 an, deren anderes Ende etwa mittig am unteren Holm 4 eingehängt ist. Durch diese Ausbildung wird in einfacher Weise eine elastische Spannung und gleichzeitig dämpfende Aufhängung der Bespannung 1 mit leichter Schräglage nach vorne erzielt, die durch die Wahl der Feder 10, vorzugsweise auch durch die Wahl der Angriffspunkte der Feder 10 und des durch mehrere Lagerstellen veränderbaren Hebelarmverhältnisses, bestimmt werden kann.The
Streifen 9 aus dem Bespannungsmaterial, welches vorzugsweise netzförmig ist, hängen lose von der Bespannung 1 herab. Dadurch wird insgesamt das Dämpfungsvermögen der Einrichtung erhöht und weniger stark geschlagene Bälle. werden bereits durch die Streifen 9 abgefangen.
Bei Nichtgebrauch kann die Rampe 2 hochgeklappt werden, sodaß der Platzbedarf der gesamten Einrichtung sehr gering ist.When not in use, the ramp 2 can be folded up, so that the space required for the entire device is very small.
Fig. 2 zeigt im Detail die Befestigung der unteren Randleiste 12, welche mit der Fixierung der Holme 4 kombiniert ist. Die normal zur Zeichenebene in Fig. 1 verlaufenden Ständer 14, welche einerseits die Rampe 2 tragen und andererseits Teil der Prallwand bilden, sind entsprechend dem seitlichen Abstand der Holme 4 mit Zapfen 18 versehen. Auf diese Zapfen 18 wird zunächst die untere Randleiste 12 aufgesteckt, an welcher mittels einer Klemmleiste 17 die Bespannung 1 befestigt ist. Anschließend werden die unteren Holme 4 auf die Zapfen 18 gesteckt und die untere Randleiste 12 dadurch fixiert.Fig. 2 shows in detail the attachment of the
Beim Ausführungsbeispiel nach Fig. 3 sind die Federn zwischen oberem und unterem Holm als Druckfedern 11 ausgebildet, beispielsweise als im Handel erhältliche Gasfedern. Die Druckfedern 11 sind mittels eines Gelenkzapfens 16 im Inneren des unteren Holmes 4 schwenkbar gelagert und greifen in eine Ausnehmung 7 eines schwenkbaren Zapfens 19 ein, auf welchen der obere Holm 5 aufsteckbar ist. Diese Anordnung zeichnet sich durch besonders geringen Platzbedarf aus. Die wegen des kleinen Hebelarmes relativ große Federkraft, beispielsweise von 800 N, ist mit handelsüblichen Gasfedern ohne weiteres zu erzielen.In the exemplary embodiment according to FIG. 3, the springs between the upper and lower spar are designed as
