Aus dem Internetartikel "
Problematisch an den Diskokugeln ist, dass ein zunehmender Bedarf an sehr großen Diskokugeln besteht, die mehrere Meter Durchmesser aufweisen können. Zum einen sind Diskokugeln mit einem Durchmesser von 3 - 4 Metern, wie sie tatsächlich verwendet werden, auf herkömmlichen Straßen nur unter besonderen Sicherheitsvorkehrungen transportierbar, und zum anderen weisen die großen Diskokugeln ein erhebliches Gewicht von mehreren 100 Kilogramm, teilweise von mehreren Tonnen auf.The problem with the disco balls is that there is an increasing demand for very large disco balls, which can be several meters in diameter. On the one hand, disco balls with a diameter of 3 - 4 meters, as actually used, are transportable on conventional roads only under special safety precautions, and on the other hand, the large disco balls have a considerable weight of several 100 kilograms, sometimes several tons.
Aufblasbare Diskokugeln sind im Stand der Technik bekannt. So wurde auf dem 'Bestival' im Robin Hill country park auf der Isle of Wight im September 2014 eine Diskokugel öffentlich zugänglich gemacht, mit einem Durchmesser von 10,33 m, die eine Innenhülle aus PVC-Stoff umfasst, die aufblasbar ist und eine Außenhülle aus einem die Innenhülle umgebenden Netz, wobei an dem Netz außen mehrere tausend Styrenspiegel mittels Kabelbindern befestigt sind.Inflatable disc balls are known in the art. For example, at the 'Bestival' in Robin Hill country park on the Isle of Wight in September 2014, a disco ball with a diameter of 10.33 m was made publicly available, which includes an inner shell of PVC fabric that is inflatable and an outer shell from a net surrounding the inner shell, wherein on the outside of the network several thousand styrene mirrors are fastened by means of cable ties.
Es ist daher Aufgabe der vorliegenden Erfindung, eine Diskokugel zur Verfügung zu stellen, die trotz ihrer Größe leicht transportierbar ist und auch ein geringeres Gewicht aufweist.It is therefore an object of the present invention to provide a disco ball that is easily transportable despite its size and also has a lower weight.
Die Aufgabe wird hinsichtlich der Vorrichtung mit einer Diskokugel mit den Merkmalen des Anspruchs 1 erfüllt.The object is achieved in terms of the device with a disco ball with the features of
Die Erfindung macht von der Idee Gebrauch, eine Diskokugel mit einer expandierbaren Innenkonstruktion zur Verfügung zu stellen, die sich während eines Transportes in einem zusammengezogenen Zustand befindet und ein geringes Volumen aufweist und daher sehr leicht transportiert werden kann, während sie bei der Anwendung auf Veranstaltungen expandiert und durchaus mit Durchmessern von mehreren Metern über einem Veranstaltungsbereich hängen kann und optisch von außen gesehen, keinen Unterschied zu herkömmlichen Styropordiskokugeln aufweist.The invention makes use of the idea of providing a disco ball with an expandable interior construction that is in a contracted state during transport and has a low volume and therefore can be transported very easily while expanding on events in use and certainly with diameters of several meters over one Event area can hang and visually seen from the outside, no difference to conventional Styropordiskokugeln has.
Die Erfindung macht insbesondere von der verblüffend einfachen Idee Gebrauch, eine aufblasbare Diskokugel zur Verfügung zu stellen, die sich während eines Transportes in einem schlaffen Zustand befindet und ein geringes Volumen aufweist und daher sehr leicht transportiert werden kann, während sie bei der Anwendung auf Veranstaltungen aufgeblasen ist.In particular, the invention makes use of the amazingly simple idea of providing an inflatable disco ball that is in a limp state during transport and has a low volume and therefore can be easily transported while inflating at events is.
Die Außenhülle ist außen um die Innenkonstruktion gelegt. Sie kann flächig auf der Innenhülle aufliegen.The outer shell is laid out around the inner construction. It can lie flat on the inner shell.
Erfindungsgemäß weist die Außenhülle eine Mehrzahl an etwa linsenförmigen Segmenten auf, die nebeneinander angeordnet sind und benachbarte linsenförmige Segmente sind miteinander zur Außenhülle verbunden. Die linsenförmigen Segmente sind voneinander wieder lösbar oder trennbar miteinander verbunden. Dadurch ist es möglich, die Außenhülle nicht in einem Stück, sondern in mehreren Segmenten zu transportieren und erst am Veranstaltungsort die Segmente zur Außenhülle zusammenzusetzen.According to the invention, the outer shell has a plurality of approximately lenticular segments, which are arranged side by side and adjacent lenticular segments are connected to each other to the outer shell. The lenticular segments are mutually releasably or separably connected to each other. This makes it possible to transport the outer shell not in one piece, but in several segments and only at the venue to assemble the segments to the outer shell.
Die erfindungsgemäße Diskokugel weist eine aufblasbare Innenhülle auf, die im aufgeblasenen Zustand kugelförmig ausgebildet ist und die die Außenhülle ebenfalls in einer Kugelgestalt hält. Die Erfindung benutzt die überraschend einfache Idee, eine herkömmliche Innenhülle, die aus einem biegsamen Kunststoff besteht und im Wesentlichen luftundurchlässig, vorzugsweise ganz luftundurchlässig ist, zur Verfügung zu stellen und diese schlaffe Innenhülle mit einer Außenhülle zu ummanteln, wobei die Außenhülle vorzugsweise mit den bekannten Spiegelstücken einer Diskokugel versehen ist. Durch Aufblasen der Innenhülle wird gleichzeitig die Außenhülle auf eine Kugelform gebracht.The disco ball according to the invention has an inflatable inner shell, which is spherical in the inflated state and which also holds the outer shell in a spherical shape. The invention makes use of the surprisingly simple idea of providing a conventional inner shell, which is made of a flexible plastic and is substantially impermeable to air, preferably completely impermeable to air, and to cover this loose inner shell with an outer shell, wherein the outer shell preferably with the known mirror pieces a disco ball is provided. By inflating the inner shell, the outer shell is simultaneously brought to a spherical shape.

Vorzugsweise sind alle Außenseiten mit Spiegelstücken überdeckt. Die Spiegelstücke sind an den Rändern der Segmente, vorzugsweise der Kontur der Segmente angepasst, d. h. sie weichen von der Form der Spiegelstücke, die entlang der übrigen Innenfläche der Segmente verwendet wird, ab. Die Spiegelstücke können alle baugleich sein, sie sind vorzugsweise quadratisch, sie können jedoch auch unterschiedliche Bauformen aufweisen, sie können insbesondere auch rechteckig, kreisförmig, sechseckig usw. ausgebildet sein. Die Formen der Spiegelstücke können auch vermischt verwendet werden.The segments run along the outer shell from the north to the south pole, they are tapered at the north and south pole and at the equator of the disco ball, the segments have their highest width. The lenticular segments are each occupied on its outer side with mirror pieces, the mirror pieces can all be the same design, but they can also have different outer shapes; Conveniently, the mirror pieces glued to the outer sides of the segments and cover the outer sides of the segments substantially completely, preferably completely. Preferably, all outer sides are covered with mirror pieces. The mirror pieces are adapted at the edges of the segments, preferably the contour of the segments, ie they deviate from the shape of the mirror pieces used along the remaining inner surface of the segments. The mirror pieces may all be identical, they are preferably square, but they may also have different designs, they may in particular also be rectangular, circular, hexagonal, etc. formed. The shapes of the mirror pieces can also be used mixed.
Darüber hinaus können die Spiegel auch farbig ausgebildet sein. Alle Spiegel können dieselbe Farbe aufweisen oder sie können untereinander verschiedene Farben aufweisen.In addition, the mirrors can also be colored. All mirrors can be the same color or they can have different colors among each other.

Die linsenförmigen Segmente sind während des Transportes vorzugsweise in einer Box gestapelt. Sie werden nach dem Transport aus der Box herausgehoben, nebeneinander gelegt und vorzugsweise werden die Klettbänder entlang der Ränder der linsenförmigen Segmente mit einem komplementären Klettband miteinander verbunden. Es ist alternativ auch denkbar, die linsenförmigen Elemente auf die Innenkugel direkt aufzubringen und dort beispielsweise mittels Klettbändern zu befestigen.The lenticular segments are preferably stacked in a box during transport. They are lifted out of the box after transport, placed next to each other and preferably the Velcro strips along the edges of the lenticular segments are connected to each other with a complementary Velcro tape. It is alternatively also conceivable to apply the lenticular elements directly to the inner ball and fasten it there by means of Velcro strips, for example.
Es ist jedoch auch denkbar, die linsenförmigen Segmente anderweitig miteinander zu verbinden, etwa durch knopfartige Verbindungen, durch Klemmverbindungen oder Ähnliches.However, it is also conceivable to otherwise connect the lenticular segments with each other, for example by button-like connections, by clamping connections or the like.
In einer besonders bevorzugten Ausführungsform der Erfindung ist an einem Nordpol ein Ring vorgesehen, an dem Spitzen jedes linsenförmigen Segmentes befestigt sind und der Ring weist Hängeeinrichtungen auf, von denen Seile zum Aufhängen der Diskokugel abgehen. Die linsenförmigen Segmente können aufgrund der auf ihnen aufgebrachten Spiegelstücke erhebliche Gewichte von vielen Kilogramm, teilweise bis 100 Kilogramm pro Segment aufweisen. Zur Sicherung der Segmente sind die Spitzen jedes linsenförmigen Segmentes an dem Ring, vorzugsweise einem Metallring, befestigt. Dazu kann der Metallring Löcher oder Bohrungen aufweisen. Die linsenförmigen Segmente können ebenfalls Löcher aufweisen und durch die Löcher sind Schrauben geführt, mit denen die Spitzen der Segmente an den Löchern des Ringes befestigt werden können.In a particularly preferred embodiment of the invention, a ring is provided at a north pole, are attached to the tips of each lenticular segment and the ring has hangers, from which depart cables for suspending the disco ball. Due to the mirror pieces applied to them, the lenticular segments can have considerable weights of many kilograms, sometimes up to 100 kilograms per segment. To secure the segments, the tips of each lenticular segment are attached to the ring, preferably a metal ring. For this purpose, the metal ring may have holes or holes. The lenticular segments may also have holes and through the holes screws are guided, with which the tips of the segments can be attached to the holes of the ring.
Die gesamte Diskokugel wird ebenfalls am Ring mit ihrem Gewicht aufgehängt. Dazu sind an dem Ring weitere Hängeeinrichtungen in Form von Löchern, Ösen oder Ähnlichem vorgesehen, die ein entsprechendes Gewicht tragen können.The entire disco ball is also hung on the ring with its weight. For this purpose, further hanging devices in the form of holes, loops or the like are provided on the ring, which can carry a corresponding weight.
Vorzugsweise ist ein Kompressor oder Gebläse am Nordpol angeordnet, der über einen Zuluftschacht mit der Innenhülle in Verbindung steht. Es hat sich gezeigt, dass Innenhüllen, die aus Kunststoff, wie Polyurethan, Polyethylen oder Ähnlichem, bestehen, über die Zeit Luft verlieren oder aufgrund von Temperaturschwankungen im Raum ihr Volumen verändern. Um diese Volumenänderung oder den Luftverlust auszugleichen, ist ein Kompressor vorgesehen, der über einen Zuluftschacht Umgebungsluft in die Innenhülle einblasen kann.Preferably, a compressor or blower is arranged at the north pole, which communicates with the inner shell via a supply air shaft. It has been found that inner shells, which are made of plastic, such as polyurethane, polyethylene or the like, lose air over time or change their volume due to temperature fluctuations in the room. To compensate for this change in volume or the loss of air, a compressor is provided, which can blow ambient air into the inner shell via a supply air shaft.
Es ist des Weiteren ein Überlaufventil vorgesehen, das automatisch bei zu hoch werdendem Innendruck der Innenhülle Luft aus ihr herauslässt.Furthermore, an overflow valve is provided which automatically lets air out of it when the internal pressure of the inner shell becomes too high.
Die Aufgabe wird in ihrem zweiten Aspekt durch ein Verfahren mit den Merkmalen des Anspruchs 6 gelöst, indem eine Außenhülle mit außen aufgebrachten Spiegelstücken zur Verfügung gestellt wird und in die Außenhülle eine expandierbare Innenkonstruktion eingebracht wird.The object is achieved in its second aspect by a method having the features of
Erfindungsgemäß wird eine aufblasbare Innenhülle als Innenkonstruktion verwendet. Die Innenhülle wird in die Außenhülle eingebracht, dann wird sie aufgeblasen und dann dadurch die Außenhülle auf eine Kugelform expandiert.According to the invention an inflatable inner shell is used as an internal construction. The inner shell is inserted into the outer shell, then it is inflated and then by expanding the outer shell to a spherical shape.
Die Erfindung macht von der sehr einfachen, aber sehr wirkungsvollen Idee Gebrauch, die sehr groß voluminösen Diskokugeln während des Transportes auf eine kleine Form zu bringen, vorzugsweise indem die Diskokugel aufgeblasen werden kann bzw. Luft aus ihr herausgelassen werden kann. Während eines Transportes ist die Diskokugel in einem schlaffen und demontierten Zustand, während des Gebrauches während einer Veranstaltung ist die Diskokugel aufgeblasen und über einem Veranstaltungsbereich aufgehängt.
Zum Aufblasen wird vorzugsweise Umgebungsluft verwendet. Es können aber auch andere Gase verwendet werden.The invention makes use of the very simple but very effective idea to bring the very large volume disco balls during transport to a small form, preferably by the disc ball can be inflated or air can be let out of it. During a transport, the disco ball is in a floppy and disassembled state, during use during an event, the disco ball is inflated and suspended over an event area.
For inflation preferably ambient air is used. But it can also be used other gases.
Erfindungsgemäß werden baugleiche linsenförmige Segmente zur Verfügung gestellt, die an ihren Rändern miteinander verbunden nebeneinander angeordnet werden und eine schlaffe Außenhülle ausformen. Die linsenförmigen Segmente wurden oben bereits beschrieben.According to the invention identical lenticular segments are provided, which are arranged side by side at their edges and form a flabby outer shell. The lenticular segments have already been described above.
Die beschriebenen Verfahren eignen sich insbesondere zur Montage einer der oben beschriebenen Diskokugeln.The described methods are particularly suitable for mounting one of the disco balls described above.
Günstigerweise wird jedes der linsenförmigen Segmente mit einer Spitze am Ring befestigt und die Diskokugel an Hängeeinrichtungen des Ringes an einer Decke aufgehängt. Die Segmente können mittels Schrauben oder anderer Verschlüsse fest an einem stabilen Ring, vorzugsweise einem Metall- oder Stahlring festgeschraubt und montiert werden. Dabei sind die gängigen Sicherheitsvorschriften zu beachten.Conveniently, each of the lenticular segments is attached to the ring with a tip and the disco ball suspended from hangers of the ring on a ceiling. The segments can be firmly screwed and mounted by means of screws or other fasteners to a stable ring, preferably a metal or steel ring. The usual safety regulations must be observed.
In einer Weiterbildung der Erfindung wird die Diskokugel mit einem Kompressor ausgestattet, der Kompressor steht luftleitend mit der Innenhülle in Verbindung und kann bei Druckschwankungen der Innenhülle durch Luftzufuhr oder Luftauslass den Luftinnendruck nachregulieren.In a further development of the invention, the disco ball is equipped with a compressor, the compressor is air-conducting with the inner shell in conjunction and can adjust the internal air pressure with pressure fluctuations of the inner shell by air or air outlet.
Nach der Verwendung kann die Außenhülle wieder abgenommen werden und die Innenkonstruktion geschrumpft werden, indem entweder das Innengestänge auseinandergebaut oder die Innenhülle entlüftet wird.After use, the outer shell can be removed again and the inner structure shrunk by either disassembling the inner rod or venting the inner sleeve.
