Description
Die Erfindung betrifft ein flächiges Element zum Bilden eines Teils eines Sportgeräts oder Musikinstruments, wobei das Element einen plattenförmigen Grundkörper aufweist, der zumindest teilweise aus Holz gebildet ist. Weiterhin betrifft die Erfindung ein Sportgerät, das zumindest teilweise durch ein solches flächiges Element gebildet ist sowie ein Musikinstrument, das zumindest teilweise durch ein solches flächiges Element gebildet ist. The invention relates to a planar element for forming a part of a sports device or musical instrument, wherein the element has a plate-shaped base body which is at least partially formed from wood. Furthermore, the invention relates to a sports equipment, which is at least partially formed by such a sheet-like element and a musical instrument, which is at least partially formed by such a sheet-like element.
Aus der
Allerdings wirkt die thermische Behandlung auf das gesamte Element gleichförmig ein, so dass sich lokale Unterschiede mit Bezug auf die mechanischen Eigenschaften des Elements durch diese Behandlung nicht erzielen lassen. However, the thermal treatment acts uniformly on the entire element, so that local differences with respect to the mechanical properties of the element can not be achieved by this treatment.
Der Erfindung liegt die Aufgabe zugrunde, ein entsprechendes verbessertes flächiges Element anzugeben. Insbesondere soll das Element derart gestaltet sein, dass es sich herstellungstechnisch vorteilhaft in Teilbereichen mit Verstärkungen versehen lässt. Außerdem soll ein entsprechendes Sportgerät und ein entsprechendes Musikinstrument angegeben werden. The invention has for its object to provide a corresponding improved sheet element. In particular, the element should be designed in such a way that it can advantageously be provided in sections with reinforcements. In addition, a corresponding sports equipment and a corresponding musical instrument should be specified.
Diese Aufgabe wird gemäß der Erfindung mit den in den unabhängigen Ansprüchen genannten Gegenständen gelöst. Besondere Ausführungsarten der Erfindung sind in den abhängigen Ansprüchen angegeben. This object is achieved according to the invention with the objects mentioned in the independent claims. Particular embodiments of the invention are indicated in the dependent claims.
Gemäß der Erfindung ist ein flächiges Element zum Bilden eines Teils eines Sportgeräts oder Musikinstruments vorgesehen, wobei das Element einen plattenförmigen Grundkörper aufweist, der zumindest teilweise aus Holz gebildet ist. Der plattenförmige Grundkörper ist dabei derart von einem faden- oder bandartigen Werkstoff durchsetzt ist, dass der faden- oder bandartige Werkstoff abschnittsweise an den gegenüberliegenden Flachseiten des Grundkörpers verläuft. According to the invention, a planar element for forming a part of a sports device or musical instrument is provided, wherein the element has a plate-shaped main body, which is at least partially formed from wood. The plate-shaped base is in such a way traversed by a thread-like or ribbon-like material that the thread-like or ribbon-like material extends in sections on the opposite flat sides of the body.
Durch den faden- oder bandartigen Werkstoff lassen sich die mechanischen Eigenschaften des flächigen Elements gezielt lokal verändern; beispielsweise lässt sich so eine lokale Verstärkung des flächigen Elements erzielen. Insbesondere lassen sich auf diese Weise Teilbereiche des Elements mit entsprechend erhöhter Zugfestigkeit bilden. Dabei ist es nicht erforderlich, dass der Grundkörper gleichmäßig über seine Gesamtheit hinweg mit dem faden- oder bandartigen Werkstoff durchsetzt ist. Es lassen sich vielmehr lediglich Teilbereiche des Grundkörpers entsprechend gestalten, so dass sich auf besonders materialsparende Weise gezielt lokal unterschiedliche Eigenschaften des flächigen Elements verwirklichen lassen. The filament or ribbon-like material allows the mechanical properties of the planar element to be locally changed in a targeted manner; For example, a local reinforcement of the planar element can thus be achieved. In particular, partial regions of the element with correspondingly increased tensile strength can be formed in this way. It is not necessary that the main body is interspersed uniformly over its entirety with the thread or ribbon-like material. Rather, only partial areas of the basic body can be designed accordingly, so that it is possible in a particularly material-saving manner to specifically realize locally different properties of the planar element.
Bei einem Sportgerät sind entsprechende lokale Unterschiede in den mechanischen Eigenschaften oft erwünscht. Beispielsweise kann es im Fall eines Tischtennisschlägers vorteilhaft sein, wenn das flächige Element – hier in Form des Schlägerholzes – lediglich in der so genannten „Trefferzone“ entsprechende Verstärkungen aufweist. In a sports device, corresponding local differences in mechanical properties are often desired. For example, in the case of a table tennis racket, it can be advantageous if the planar element - here in the form of the club wood - has corresponding reinforcements only in the so-called "hit zone".
Analoges gilt mit Bezug auf Musikinstrumente, insbesondere wenn das flächige Element einen Resonanzkörper bildet; durch entsprechende Verstärkungen lassen sich die Schwingungseigenschaften gezielt modifizieren. The same applies with respect to musical instruments, in particular when the planar element forms a resonant body; By appropriate reinforcements, the vibration properties can be selectively modified.
Bei dem plattenförmigen Grundkörper handelt es sich vorzugsweise um ein Holzfurnier. The plate-shaped base body is preferably a wood veneer.
Vorzugsweise ist der faden- oder bandartige Werkstoff mit dem plattenförmigen Grundkörper vernäht. Hierdurch lässt sich das Element besonders einfach herstellen. Dabei kann das Element lediglich aus dem Grundkörper und dem faden- oder bandartige Werkstoff gebildet sein. Es ist also kein Klebstoff, Harz oder dergleichen erforderlich. Auch ist dementsprechend nach der Verbindung der beiden genannten Teile keine Trocknungszeit erforderlich. Preferably, the thread-like or ribbon-like material is sewn to the plate-shaped base body. This makes it easy to produce the element. In this case, the element can be formed only from the base body and the thread or ribbon-like material. So it is not an adhesive, resin or the like required. Also, accordingly, after the connection of the two parts mentioned no drying time is required.
Vorzugweise besteht der faden- oder bandartige Werkstoff aus Carbon, Aramid oder Glasfasern. Diese Fasern sind zur Erzielung verstärkter Stellen besonders geeignet. Dabei weisen diese Fasern ein vergleichsweise geringes Gewicht auf, so dass sich das flächige Element insgesamt besonders leichtgewichtig gestalten lässt. Preferably, the thread or ribbon-like material made of carbon, aramid or glass fibers. These fibers are particularly suitable for obtaining reinforced areas. In this case, these fibers have a comparatively low weight, so that the overall surface element can be made particularly lightweight.
Gemäß einem weiteren Aspekt der Erfindung ist ein Sportgerät vorgesehen, welches zumindest teilweise durch ein erfindungsgemäßes flächiges Element gebildet ist. According to a further aspect of the invention, a sports device is provided, which is at least partially formed by a flat element according to the invention.
Insbesondere kann es sich hierbei um einen Tischtennisschläger oder einen Ski handeln. In particular, this may be a table tennis racket or a ski.
Gemäß einem noch weiteren Aspekt der Erfindung ist ein Musikinstrument vorgesehen, welches zumindest teilweise durch ein erfindungsgemäßes flächiges Element gebildet ist. According to yet another aspect of the invention, a musical instrument is provided, which is at least partially formed by a flat element according to the invention.
Dabei weist das Musikinstrument vorzugsweise einen Resonanzkörper auf, der zumindest teilweise durch ein das flächige Element gebildet ist. Insbesondere kann es sich bei dem Musikinstrument um eine Gitarre handeln. In this case, the musical instrument preferably has a resonance body, which is at least partially formed by a flat element. In particular, the musical instrument may be a guitar.
Die Erfindung wird im Folgenden anhand eines Ausführungsbeispiels und mit Bezug auf die Zeichnungen näher erläutert. Es zeigen: The invention is explained in more detail below with reference to an embodiment and with reference to the drawings. Show it:

Durch die Anordnung der Stiche beim Nähen lassen sich dabei Verstärkungen mit gezielter Richtungsabhängigkeit bewirken. By arranging the stitches when sewing can thereby cause reinforcements with targeted directional dependence.
Zur Herstellung kann eine Nähmaschine verwendet werden, beispielsweise eine CNC gesteuerte Nähmaschine (CNC: computerized numerical control; computergestützte numerische Steuerung). For manufacturing, a sewing machine may be used, for example, a CNC-controlled sewing machine (CNC: computerized numerical control).

Wie in
Es können also Verstärkungen an beliebigen Stellen gebildet werden; im Vergleich hierzu weist ein Carbongewebe an allen Stellen eine einheitliche Festigkeit auf. So reinforcements can be formed anywhere; In comparison, a carbon fabric has a uniform strength at all points.
Ein entsprechendes flächiges Element kann auch zur Bildung eines Musikinstruments dienen, insbesondere zur Bildung eines Resonanzkörpers des Musikinstruments. Bei dem Musikinstrument kann es sich beispielsweise um eine Gitarre oder ein anderes Saiteninstrument handeln. Beispielsweise kann also bei einer Gitarre der Resonanzboden an verschiedenen Stellen mit Carbon oder einem anderen Material verstärkt sein. A corresponding planar element can also serve to form a musical instrument, in particular for forming a resonator of the musical instrument. The musical instrument may be, for example, a guitar or other stringed instrument. For example, in a guitar, the soundboard may be reinforced at various points with carbon or other material.
Weitere Einsatzmöglichkeiten der Erfindung bestehen auch im Bereich des Modellbaus; hier können beispielsweise Flügel von Modellflugzeugen oder Schiffsmodelle an bestimmten Stellen entsprechend verstärkt werden. Other uses of the invention also exist in the field of model making; Here, for example, wings of model airplanes or ship models can be reinforced accordingly at certain points.
