Abstract

The trampoline (1) has a jumping mat (3) fixed on a frame structure (2) by an elastic element. The jumping mat is formed by low-stretch yarns made of textile fabrics. The low-stretch yarns form a string, where a two-dimensional structure of the textile fabric is formed by the string. The low-stretch yarns are made of aramid or para-aramid, particularly Levlar(RTM: Para-aramid synthetic fiber) or twaron, polyethylene, Dyneema(RTM: Ultra-high-molecular-weight polyethylene), carbon, and Vectran(RTM: aromatic polyester).

Description

Die Erfindung betrifft ein Trampolin.The invention relates to a trampoline.

Trampoline werden in großer Anzahl als Sportgeräte eingesetzt, und zwar im Bereich des Leistungssports ebenso wie in Bereich des Hobbysports und im Freizeitbereich.Trampolines are used in large numbers as sports equipment, in the field of competitive sports as well as in the field of amateur sports and leisure.

Derartige Trampoline weisen ein Sprungtuch auf, das mit elastischen Elementen, insbesondere Federn, an einem Rahmengestell befestigt ist. Das typischerweise zusammenklappbare und damit transportable Rahmengestell kann flexibel auf Böden von Turn- und Sporthallen, oder auch im Outdoorbereich, beispielsweise in Freizeitparks, aufgestellt werden.Such trampolines have a jumping cloth, which is fastened with elastic elements, in particular springs, to a frame. The typically collapsible and thus transportable frame can be flexibly placed on floors of gymnasiums and sports halls, or in the outdoor area, for example, in amusement parks.

Die Sprungtücher derartiger Trampoline bestehen aus textilen Flächengebilden mit einer gitterförmigen Struktur. Typischerweise bestehen derartige Sprungtücher aus Kunstfasern wie Polyestergarnen oder Polyamidgarnen.The jump sheets of such trampolines consist of textile fabrics with a latticed structure. Typically, such jump sheets are made of synthetic fibers such as polyester yarns or polyamide yarns.

Die so ausgebildeten Sprungtücher können rationell und relativ kostengünstig hergestellt werden. Zur Montage eines Sprungtuchs am Trampolin wird dieses mittels der elastischen Elemente in die Rahmenkonstruktion eingespannt. Das so montierte, neue Sprungtuch weist eine bestimmte Einspannlänge in Quer- und Längsrichtung auf. Bereits nach einigen Tagen oder Wochen des Gebrauchs des Trampolins dehnen sich diese Sprungtücher dauerhaft um etwa 2 bis 2,5 %. Damit auch dann noch die Sprungtücher im normativ vorgeschriebenen Längenbereich liegen, werden die Sprungtücher bei Herstellung so dimensioniert, dass deren Längen beziehungsweise Breiten am unteren Ende des normativ vorgeschriebenen Toleranzbereiches liegen, so dass gewährleistet ist, dass auch während des Gebrauchs des Sprungtuchs dessen Längs- und Querausdehnungen trotz der auftretenden Dehnung noch in den normativ vorgeschriebenen Toleranzgrenzen liegen.The so-formed jump cloths can be produced efficiently and relatively inexpensively. To mount a jumping cloth on the trampoline this is clamped by means of elastic elements in the frame construction. The so-mounted, new jump sheet has a certain clamping length in the transverse and longitudinal direction. After just a few days or weeks of using the trampoline, these jumps stretch permanently by about 2 to 2.5%. So that even then the jump cloths are within the normatively prescribed length range, the jump cloths are dimensioned in production so that their lengths or widths are at the lower end of normatively prescribed tolerance range, so as to ensure that even during use of the jump cloth its longitudinal and transverse dimensions despite the elongation still lying within the normative prescribed tolerance limits.

Bei bestimmten Einsatzbereichen, wie zum Beispiel dem Einsatz des Trampolins im Bereich des Leistungssports, sind derartige Dehnungen des Sprungtuchs nicht akzeptabel, da sich dadurch die Sprungeigenschaften des Trampolins spürbar verschlechtern. Dies führt dazu, dass bei derartigen Einsatzzwecken die Sprungtücher bereits nach kurzen Gebrauchszeiten durch neue ersetzt werden müssen. Dies stellt einen erheblichen Kostenfaktor dar. Zudem erfordert das häufige Auswechseln auch einen unerwünscht hohen Zeitaufwand.In certain applications, such as the use of the trampoline in the field of competitive sports, such expansions of the jump cloth are unacceptable, since thereby the jumping properties of the trampoline deteriorate noticeably. As a result, in such applications, the jump cloths have to be replaced by new ones already after short periods of use. This represents a significant cost factor. In addition, the frequent replacement also requires an undesirably high amount of time.

Der Erfindung liegt die Aufgabe zugrunde, ein Trampolin bereitzustellen, welches dauerhaft hohen Qualitätsansprüchen genügt.The invention has for its object to provide a trampoline, which meets permanently high quality standards.

Zur Lösung dieser Aufgabe sind die Merkmale des Anspruchs 1 vorgesehen. Vorteilhafte Ausführungsformen und zweckmäßige Weiterbildungen der Erfindung sind in den Unteransprüchen beschrieben.To solve this problem, the features of claim 1 are provided. Advantageous embodiments and expedient developments of the invention are described in the subclaims.

Das erfindungsgemäße Trampolin umfasst ein durch elastische Elemente an eine Rahmenkonstruktion befestigtes Sprungtuch. Das Sprungtuch besteht aus einem dehnungsarme Garne enthaltenden textilen Flächengebilde. Die dehnungsarmen Garne bilden Strings aus, aus welchen dann das Flächengebilde aufgebaut ist.The trampoline according to the invention comprises a jump cloth fixed to a frame construction by elastic elements. The hammock consists of a low-stretch yarn-containing textile fabric. The low-stretch yarns form strings, from which then the fabric is built.

Die Strings werden bevorzugt durch ein Verdrehen oder Verwinden mehrerer dehnungsarmer Garne hergestellt. Der resultierende String weist somit einen schnurartigen Aufbau auf, wobei ein solcher String im Gegensatz zu Bändern, die auch zur Herstellung von Sprungtüchern verwendet werden können, keine flächige Form, sondern einen im Wesentlichen kreisförmigen Querschnitt aufweist.The strings are preferably made by twisting or twisting several low-stretch yarns. The resulting string thus has a cord-like structure, wherein such a string, in contrast to bands that can also be used for the production of jump cloths, not a flat shape, but has a substantially circular cross-section.

Aus den einzelnen Strings ist das Flächengebilde aufgebaut. Dieses ist bevorzugt als Gewebe ausgebildet.From the individual strings, the fabric is constructed. This is preferably formed as a fabric.

Vorteilhaft hierbei ist, dass die Gewebe in Bahnen hergestellt werden. Diese Bahnen können entsprechend der Maße der Sprungtücher zugeschnitten werden. Das so konfektionierte Sprungtuch wird an seinen Rändern mit einem Einfass-Band versehen. Da zur Herstellung derartiger Sprungtücher das Verflechten und anschließende Vernähen einzelner Bänder entfällt, können diesbezüglich die Fertigungszeiten für das Sprungtuch reduziert werden.The advantage here is that the tissues are produced in webs. These tracks can be tailored according to the size of the jump sheets. The made-up jump sheet is provided at its edges with a binding band. Since the interweaving and subsequent sewing of individual bands is omitted for the preparation of such jump beds, the production times for the jump cloth can be reduced in this regard.

Besonders vorteilhaft werden zur Herstellung des Sprungtuchs Gewebearten verwendet, die zu einer hohen Verschiebefestigkeit des Sprungtuchs führen. Beispiele hierfür sind Gewebe mit Scheindreherverbindungen.Particularly advantageous for the preparation of the jump cloth tissue types are used, which lead to a high resistance to displacement of the jump cloth. Examples include tissues with false twist compounds.

Weiterhin vorteilhaft bildet das Flächengebilde des Sprungtuchs eine Gitterstruktur mit geringer konstruktiver Dehnung, das heißt eine Struktur, die keine große Grundfreiheit zu internen Bewegungen innerhalb des Gitters aufweist, so dass dadurch bedingte Energieverluste gering gehalten werden.Further advantageously, the sheet of the jump cloth forms a grid structure with low structural elongation, that is, a structure that has no great freedom of movement to internal movements within the grid, so that energy losses caused by it are kept low.

Bei dem erfindungsgemäßen Sprungtuch wird durch den Einsatz des dehnungsarmen Garnes die maximale technische Belastbarkeit dauerhaft erhalten, das heißt das mit diesem Sprungtuch ausgestattete Trampolin kann bei einer gleichmäßigen Leistungsabgabe über einen langen Zeitraum genutzt werden. Damit können die erfindungsgemäßen Trampoline insbesondere im Leistungssport eingesetzt werden. Gerade bei derartigen Anwendungen im Spitzensport können die erfindungsgemäßen Trampoline vorteilhaft eingesetzt werden, da dort bereits geringe Beeinträchtigungen der Leistungsabgabe nicht akzeptabel sind. Diese Anforderung wird mit dem erfindungsgemäßen Trampolin erfüllt.In the case of the jumping mat according to the invention, the maximum technical load capacity is permanently maintained by the use of the low-stretch yarn, that is, the trampoline equipped with this jumping towel can be used over a long period of time with a uniform power output. Thus, the trampolines according to the invention can be used in particular in competitive sports. Especially in such applications in elite sports trampolines according to the invention can be used advantageously, since even there are small impairments of the power output are not acceptable. This requirement is met with the trampoline according to the invention.

Die dehnungsarmen Garne können beispielsweise aus Aramiden, insbesondere para-Aramiden wie Kevlar oder Twaron, bestehen.The low-stretch yarns may for example consist of aramids, especially para-aramids such as Kevlar or Twaron.

Ebenso können die dehnungsarmen Garne aus Polyethylen bestehen.Similarly, the low-stretch yarns can be made of polyethylene.

Besonders geringe Dehnungen werden mit dehnungsarmen Garnen, die aus Carbonfasern bestehen, erhalten.Particularly low elongations are obtained with low-stretch yarns consisting of carbon fibers.

Ebenso eignen sich hierfür dehnungsarme Garne aus Vectran-Fasern, das heißt Fasern bestehend aus Flüssigkristallpolymeren.Also suitable for this low-stretch yarns of Vectran fibers, that is, fibers consisting of liquid crystal polymers.

Besonders vorteilhaft bilden die Sprungtücher des erfindungsgemäßen Trampolins textile Flächengebilde, die aus einer Mischung der dehnungsarmen Garne mit Kunstfasern bestehen. Derartige Kunstfasern können Polyestergarne oder Polyamidgarne sein, die üblicherweise zur Herstellung von Sprungtüchern verwendet werden.Particularly advantageously, the jump sheets of the trampoline according to the invention form textile fabrics which consist of a mixture of the low-stretch yarns with synthetic fibers. Such synthetic fibers may be polyester yarns or polyamide yarns which are commonly used to make jump cloths.

Durch die Mischung der dehnungsarmen Garne mit Kunstfasern können einerseits die elastischen Eigenschaften der Sprungtücher vorgegeben und eingestellt werden. Zudem ergibt sich durch die Verwendung derartiger Mischungen gegenüber Sprungtüchern, die nur aus dehnungsarmen Garnen bestehen, ein erheblicher Kostenvorteil, da die Kunstfasern erheblich kostengünstiger als die dehnungsarmen Garne sind.By mixing the low-stretch yarns with synthetic fibers on the one hand, the elastic properties of the jump cloths can be set and adjusted. In addition, results from the use of such mixtures over slippers, which consist only of low-stretch yarns, a significant cost advantage, since the synthetic fibers are much cheaper than the low-stretch yarns.

Figur 1 zeigt schematisch ein Ausführungsbeispiel eines Trampolins 1, welches als wesentliche Komponenten eine Rahmenkonstruktion 2 und ein darin gelagertes Sprungtuch 3 aufweist. FIG. 1 schematically shows an embodiment of a trampoline 1, which has as essential components a frame construction 2 and a stored therein jump sheet 3.

Die Rahmenkonstruktion 2 besteht im Wesentlichen aus einem rechteckigen Rahmen 4 und mit diesem verbundenen Standfüßen 5 zum Aufstellen auf einer Unterlage. Generell kann die Rahmenkonstruktion 2 dabei zusammenklappbar sein.The frame structure 2 consists essentially of a rectangular frame 4 and connected thereto feet 5 for placement on a Document. In general, the frame construction 2 can be collapsible.

In den Rahmen 4 der Rahmenkonstruktion 2 ist, wie aus Figur 2 ersichtlich, das Sprungtuch 3 eingespannt. Hierzu werden entlang des gesamten Umfangs des Sprungtuchs 3 Federn 6 als elastische Elemente befestigt, die dann an der Innenseite des Rahmens 4 fixiert werden.In the frame 4 of the frame structure 2 is as out FIG. 2 seen, the jump sheet 3 clamped. For this purpose, 3 springs 6 are attached as elastic elements along the entire circumference of the jump cloth, which are then fixed to the inside of the frame 4.

Wie aus Figur 1 ersichtlich, sind die Federn 6 durch Abdeckungen 7 abgedeckt, um die Gefahr von Verletzungen durch Kontakt der das Trampolin 1 nutzenden Person mit den Federn 6 zu vermeiden.How out FIG. 1 can be seen, the springs 6 are covered by covers 7 to avoid the risk of injury from contact of the person using the trampoline 1 with the springs 6.

Figur 3 zeigt ein Ausführungsbeispiel des Sprungtuchs 3 für das Trampolin 1 gemäß den Figuren 1 und 2. FIG. 3 shows an embodiment of the jump sheet 3 for the trampoline 1 according to the Figures 1 and 2 ,

Das dort dargestellte Sprungtuch 3 ist an seinen Rändern mit einem Einfassband 8 eingefasst. Dieses Einfassband 8 ist mit dem Sprungtuch 3 vernäht. Beim Einnähen werden entlang der Faltkante des Einfassbands 8 Einhängestifte 9 mit von der Faltkante hervorstehenden Ösen 9a eingearbeitet, welche zum Einhängen der Federn 6 dienen.The jumping towel 3 shown there is bordered at its edges with a binding tape 8. This binding tape 8 is sewn to the jumping cloth 3. When sewing 8 Einhängestifte 9 are incorporated with protruding from the fold edge eyelets 9a along the folded edge of the edging strip, which serve to mount the springs 6.

Das Sprungtuch 3 selbst besteht aus einem Gewebe, wobei in diesem Gewebe einzelne Strings zu einem Flächengebilde verwoben sind. Die Strings bestehen aus einzelnen Garnen, die miteinander verwunden oder verdreht sind.The jump sheet 3 itself consists of a fabric, in which tissue individual strings are woven into a sheet. The strings consist of individual yarns that are twisted or twisted together.

Prinzipiell können die Strings vollständig aus dehnungsarmen Garnen bestehen. Alternativ bestehen die Strings aus einer Mischung von dehnungsarmen Garnen mit Kunstfasern bestehen. Die Kunstfasern bestehen aus Polyestergarnen oder Polyamidgarnen.In principle, the strings can consist entirely of low-stretch yarns. Alternatively, the strings consist of a mixture of low stretch yarns with synthetic fibers. The synthetic fibers consist of polyester yarns or polyamide yarns.

Die dehnungsarmen Garne können aus Aramiden bestehen. Besonders geeignet sind para-Aramide wie Kevlar oder Twaron, die sehr dehnungsarm sind. Um eine hohe Witterungsbeständigkeit zu erhalten können diese dehnungsarmen Garne eine Teflon (PTFE-)Beschichtung aufweisen.The low-stretch yarns can consist of aramids. Particularly suitable are para-aramids such as Kevlar or Twaron, which are very low-expansion. Around To obtain high weather resistance, these low-elongation yarns may have a Teflon (PTFE) coating.

Weiterhin können dehnungsarme Garne für die Strings aus Polyethylen bestehen. Ein Beispiel für derartige Garne sind Dyneema-Garne.Furthermore, low-stretch yarns for the strings can be made of polyethylene. An example of such yarns are Dyneema yarns.

Als besonders dehnungsarme Garne eignen sich Garne aus Carbon-Fasern. Diese Carbon-Fasern sind nicht nur extrem dehnungsarm, sondern weisen auch eine sehr hohe Stabilität gegen UV-Lichteinstrahlung auf.Yarns made of carbon fibers are particularly suitable as yarns with particularly low stretch. These carbon fibers are not only extremely low-stretch, but also have a very high stability against UV light radiation.

Schließlich können auch Vectran-Fasern zur Bildung dehnungsarmer Garne für die Strings 3 verwendet werden. Diese können insbesondere mit Polyester verwunden oder verdreht werden. Vectran ist ein thermoplastisches mehrfaseriges Garn, das aus geschmolzenem Flüssigkristallpolymer gesponnen wird.Finally, Vectran fibers can also be used to form low stretch yarns for the strings 3. These can be twisted or twisted especially with polyester. Vectran is a thermoplastic multifilament yarn spun from molten liquid crystal polymer.

Generell können auch mehrere der genannten dehnungsarmen Garne in Kombination zur Ausbildung der Strings verwendet werden.In general, several of the mentioned low-stretch yarns can be used in combination to form the strings.
