Abstract

Die Erfindung betrifft einen Helm (10), insbesondere Fahrradhelm, mit mehreren Belüftungsöffnungen (16) und wenigstens einem Verdunstungskühler (18), welcher in einer Belüftungsöffnung (16) angeordnet ist.The invention relates to a helmet (10), in particular bicycle helmet, with a plurality of ventilation openings (16) and at least one evaporative cooler (18), which is arranged in a ventilation opening (16).

Description

Die vorliegende Erfindung betrifft einen Helm, insbesondere Fahrradhelm, mit mehreren Belüftungsöffnungen.The present invention relates to a helmet, in particular bicycle helmet, with a plurality of ventilation openings.

Ein derartiger Helm ist grundsätzlich bekannt. Die Belüftungsöffnungen dienen dazu, Luft, insbesondere in Form von Fahrtwind, an den Kopf eines Trägers des Helms zu leiten, um auf diese Weise für eine gewisse Kühlung des Kopfes zu sorgen.Such a helmet is known in principle. The ventilation openings are used to direct air, in particular in the form of wind, to the head of a wearer of the helmet, in order to provide in this way for a certain cooling of the head.

Aufgabe der Erfindung ist es, auf einfache und kostengünstige Weise den Tragekomfort eines Helms der eingangs genannten Art weiter zu verbessern.The object of the invention is to improve the wearing comfort of a helmet of the type mentioned in a simple and cost-effective manner.

Die Aufgabe wird durch einen Helm mit den Merkmalen des Anspruchs 1 und insbesondere dadurch gelöst, dass wenigstens ein Verdunstungskühler in einer Belüftungsöffnung angeordnet ist.The object is achieved by a helmet with the features of claim 1 and in particular by the fact that at least one evaporative cooler is arranged in a ventilation opening.

Der Erfindung liegt der allgemeine Gedanke zugrunde, die Kühlfunktion des Helms nicht auf eine bloße Luftzirkulation durch die Belüftungsöffnungen zu beschränken, sondern zusätzlich durch einen eigens dafür vorgesehenen Verdunstungskühler zu unterstützen, welcher rein passiv nach dem Prinzip der Kühlung durch Trocknung und Verdunstung arbeitet. Auf diese Weise wird die Kühlung des Kopfes eines Helmträgers signifikant verstärkt und der Tragekomfort des Helms insgesamt erhöht.The invention is based on the general idea not to restrict the cooling function of the helmet to a mere air circulation through the ventilation holes, but also to support by a dedicated evaporative cooler, which works purely passive on the principle of cooling by drying and evaporation. In this way, the cooling of the head of a helmet wearer is significantly increased and the wearing comfort of the helmet increased overall.

Die Aktivierung des Verdunstungskühlers, genauer gesagt die Aufladung des Verdunstungskühlers mit Kühlfluid, kann in der Praxis auf einfache Weise dadurch erfolgen, dass der Helmträger den Verdunstungskühler mit Kühlfluid benetzt, beispielsweise indem er Trinkwasser aus einem Becher oder aus einer Flasche auf den Verdunstungskühler gießt oder spritzt. Dagegen braucht der Helmträger zur Deaktivierung des Verdunstungskühlers, beispielsweise während einer Bergabfahrt, lediglich den Kopf zu neigen und den Verdunstungskühler derart in den Fahrtwind zu stellen, dass in dem Verdunstungskühler gesammeltes Kühlfluid aktiv aus dem Verdunstungskühler herausgetrieben wird.The activation of the evaporative cooler, more precisely the charging of the evaporative cooler with cooling fluid, can be carried out in practice in a simple manner by the helmet carrier wetting the evaporative cooler with cooling fluid, for example by pouring or injecting drinking water from a cup or from a bottle onto the evaporative cooler , In contrast, the helmet wearer needs to deactivate the evaporative cooler, for example, during a downhill, only to tilt the head and the evaporative cooler in the wind so that in the evaporative cooler collected cooling fluid is actively expelled from the evaporative cooler.

Vorteilhafte Ausbildungen der Erfindung sind den Unteransprüchen, der Beschreibung und der Zeichnung zu entnehmen.Advantageous embodiments of the invention are described in the dependent claims, the description and the drawings.

Gemäß einer Ausführungsform ist der Verdunstungskühler in einer Belüftungsöffnung, die in einem hinteren Bereich des Helms liegt, oder zumindest in einem Abschnitt einer Belüftungsöffnung angeordnet, der in einem hinteren Bereich des Helms liegt. Auf diese Weise behindert der Verdunstungskühler nicht den Eintritt von kühlender Luft im vorderen Bereich des Helms, welcher normalerweise direkt dem Fahrtwind ausgesetzt ist, sondern verstärkt vielmehr die Kühlung in einem hinteren Bereich des Helms, welcher herkömmlicher Weise eher mäßig gekühlt wird. Die Anordnung des Verdunstungskühlers im hinteren Bereich des Helms hat darüber hinaus den Vorteil, dass dem Helmträger das Kühlfluid nicht in die Augen läuft, wenn er den Verdunstungskühler mit Kühlfluid übergießt oder bespritzt. Es versteht sich, dass ein Verdunstungskühler grundsätzlich aber auch weit in den vorderen Bereich des Helms hineinragen oder vollständig in dem vorderen Bereich des Helms angeordnet sein kann.According to one embodiment, the evaporative cooler is arranged in a ventilation opening which lies in a rear area of the helmet, or at least in a section of a ventilation opening which lies in a rear area of the helmet. In this way, the evaporative cooler does not hinder the entry of cooling air in the front region of the helmet, which is normally exposed directly to the airstream, but rather intensifies the cooling in a rear region of the helmet, which is conventionally rather moderately cooled. The arrangement of the evaporative cooler in the rear of the helmet also has the advantage that the helmet wearer, the cooling fluid does not run into the eyes when he doused or sprayed the evaporative cooler with cooling fluid. It goes without saying that, however, an evaporative cooler can in principle also project far into the front region of the helmet or can be arranged completely in the front region of the helmet.

Zu einer noch besseren Kühlung trägt bei, wenn mehrere Belüftungsöffnungen jeweils mit einem Verdunstungskühler versehen sind.An even better cooling contributes when several ventilation openings are each provided with an evaporative cooler.

Bevorzugt weist der Verdunstungskühler eine Vielzahl von Verdunstungsöffnungen auf, welche durch Stege des Verdunstungskühlers begrenzt sind. Auf diese Weise wird die für die Trocknung und Verdunstung des Kühlfluids zur Verfügung stehende Oberfläche maximiert und folglich die Kühlwirkung des Verdunstungskühlers optimiert.Preferably, the evaporative cooler on a plurality of evaporation openings, which are bounded by webs of the evaporative cooler. In this way the surface available for the drying and evaporation of the cooling fluid is maximized and consequently the cooling effect of the evaporative cooler is optimized.

Vorteilhafterweise sind die Verdunstungsöffnungen länglich ausgeprägt. Eine derart längliche Ausprägung der Verdunstungsöffnungen begünstigt den Oberflächenspannungseffekt und erleichtert somit die Überspannung der Verdunstungsöffnungen durch einen Kühlfluidfilm. Die Längsorientierung der Verdunstungsöffnungen sollte dabei mit der Längsorientierung des Helms ausgerichtet sein, damit Fahrtwind optimal in den Verdunstungskühler eingreifen und dadurch das in dem Verdunstungskühler gesammelte Kühlfluid optimal trocknen und verdunsten kann.Advantageously, the evaporation openings are elongated. Such an elongated shape of the evaporation openings favors the surface tension effect and thus facilitates the overvoltage of the evaporation openings by a cooling fluid film. The longitudinal orientation of the evaporation openings should be aligned with the longitudinal orientation of the helmet, so that wind optimally engage in the evaporative cooler and thereby optimally dry and evaporate the collected in the evaporative cooler cooling fluid.

Gemäß einer ersten Ausführungsform umfasst der Verdunstungskühler eine, insbesondere biegesteife, Gitterstruktur. Die Gitterstruktur kann eine Stärke im Bereich von mehreren Millimetern, insbesondere 1 bis 2 mm aufweisen.According to a first embodiment, the evaporative cooler comprises a, in particular rigid, lattice structure. The grid structure may have a thickness in the range of several millimeters, in particular 1 to 2 mm.

Bevorzugt definiert die Gitterstruktur eine Vielzahl von Verdunstungsöffnungen, welche derart dimensioniert sind, dass sie durch einen Film eines Kühlfluids, insbesondere durch einen Film von Trinkwasser, überspannbar sind. Auf diese Weise können nicht nur die Verdunstungsöffnungen begrenzende Stege des Verdunstungskühlers durch Kühlfluid benutzt werden, sondern die Verdunstungsöffnungen können zusätzlich durch einen Kühlfluidfilm überspannt werden, wodurch der Verdunstungskühler insgesamt mehr Kühlfluid aufnehmen und letztlich noch wirksamer kühlen kann. Des Weiteren erfüllt die Gitterstruktur insofern eine Doppelfunktion, als sie nicht nur Kühlfluid speichern, sondern auch zu einer optimalen Luftströmung durch den Helm beitragen kann.Preferably, the grid structure defines a plurality of evaporation openings which are dimensioned such that they can be over-stretched by a film of a cooling fluid, in particular by a film of drinking water. In this way, not only the evaporation openings delimiting webs of the evaporative cooler can be used by cooling fluid, but the evaporation openings can be additionally spanned by a cooling fluid film, whereby the evaporative cooler collect a total of more cooling fluid and ultimately can cool more effectively. Furthermore, the lattice structure fulfills a dual function insofar as it not only stores cooling fluid, but also contributes to optimum airflow through the helmet.

Grundsätzlich ist eine Gitterstruktur mit Spalten vorstellbar, welche sich in Längsrichtung des Helms über die gesamte Länge der Gitterstruktur erstrecken.In principle, a grid structure with columns is conceivable, which extend in the longitudinal direction of the helmet over the entire length of the grid structure.

Bevorzugt weisen die Verdunstungsöffnungen jedoch jeweils eine hexagonale Gestalt auf. Die daraus resultierende wabenförmige Gitterstruktur zeichnet sich durch einen besonders gelungenen Kompromiss aus Stabilität und räumlich optimaler Anordnung der Verdunstungsöffnungen aus. Grundsätzlich kommen aber auch andere eckige Formen für die Verdunstungsöffnungen in Betracht. Selbst runde, beispielsweise elliptische, Verdunstungsöffnungen, angeordnet insbesondere in einem Orthogonal- oder Kreuzraster, sind grundsätzlich denkbar.However, the evaporation openings preferably each have a hexagonal shape. The resulting honeycomb lattice structure is characterized by a particularly successful compromise between stability and spatially optimal arrangement of the evaporation openings. In principle, however, other angular shapes for the evaporation openings come into consideration. Even round, for example elliptical, evaporation openings, arranged in particular in an orthogonal or cross grid, are conceivable in principle.

Ferner ist es vorteilhaft, wenn die Verdunstungsöffnungen eine maximale Breite von 1,5 mm, bevorzugt 1,3 mm und besonders bevorzugt 1,2 mm aufweisen, da die Oberflächenspannung von Trinkwasser normalerweise ausreicht, um derart breite Verdunstungsöffnungen überspannende Wasserfilme auszubilden.Furthermore, it is advantageous if the evaporation openings have a maximum width of 1.5 mm, preferably 1.3 mm and particularly preferably 1.2 mm, since the surface tension of drinking water is normally sufficient to form such wide evaporation openings spanning water films.

Die Länge der Verdunstungsöffnungen kann länger als die Breite gewählt sein und beispielsweise im Bereich von mehreren Millimetern, insbesondere im Bereich von 2 bis 10 mm und bevorzugt im Bereich von 3 bis 6 mm liegen.The length of the evaporation openings may be longer than the width and, for example, in the range of several millimeters, in particular in the range of 2 to 10 mm and preferably in the range of 3 to 6 mm.

Gemäß einer zweiten Ausführungsform umfasst der Verdunstungskühler ein Schwammelement, insbesondere ein Element aus einem offenzelligen Schaumstoffmaterial, und/oder ein Element aus einem dreidimensionalen Textilgewebe. Auch ein solcher Verdunstungskühler eignet sich gut zur Aufnahme eines zur Kühlung durch Trocknung und Verdunstung vorgesehenen Kühlfluids, wie beispielsweise Trinkwasser. Es versteht sich, dass der Verdunstungskühler grundsätzlich auch eine Kombination aus Gitterstruktur, Schwammelement und/oder Textilgewebe aufweisen kann.According to a second embodiment, the evaporative cooler comprises a sponge element, in particular an element of an open-cell foam material, and / or an element of a three-dimensional textile fabric. Such an evaporative cooler is also well suited for receiving a cooling fluid intended for cooling by drying and evaporation, for example drinking water. It is understood that the evaporative cooler can basically also have a combination of grid structure, sponge element and / or textile fabric.

Nachfolgend wird die Erfindung rein beispielhaft anhand einer möglichen Ausführungsform unter Bezugnahme auf die beigefügte Zeichnung beschrieben.

The invention will be described purely by way of example with reference to a possible embodiment with reference to the accompanying drawings.
Fig. 1
shows a top view of a helmet according to the invention.

Bei dem in Fig. 1 gezeigten Helm 10 handelt es sich um einen Fahrradhelm, welcher einen vorderen Bereich 12 und einen hinteren Bereich 14 aufweist. Die Begriffe "vorne" und "hinten" beziehen sich in diesem Kontext auf die Perspektive eines Trägers des Helms 10, das heißt der vordere Bereich 12 des auf dem Kopf des Helmträgers sitzenden Helms 10 weist in die Blickrichtung des Helmträgers, während der hintere Bereich 14 den Hinterkopf des Helmträgers überdeckt.At the in Fig. 1 shown helmet 10 is a bicycle helmet, which has a front portion 12 and a rear portion 14. The terms "front" and "rear" in this context refer to the perspective of a wearer of the helmet 10, that is, the front portion 12 of the seated on the head of the helmet wearer helmet 10 points in the direction of the helmet wearer, while the rear portion 14th covered the back of the helmet wearer.

Der Helm 10 bildet mehrere Belüftungsöffnungen 16 aus. Drei dieser Belüftungsöffnungen 16 weisen eine in Längsrichtung des Helms 10 orientierte längliche Gestalt auf und erstrecken sich überwiegend im hinteren Bereich 14 des Helms 10.The helmet 10 forms a plurality of ventilation openings 16. Three of these ventilation openings 16 have an elongated shape oriented in the longitudinal direction of the helmet 10 and extend predominantly in the rear region 14 of the helmet 10.

In jede dieser drei Belüftungsöffnungen 16 ist ein Verdunstungskühler 18 eingesetzt, welcher in dem dargestellten Ausführungsbeispiel durch eine biegesteife Gitterstruktur 20 gebildet ist. Jede Gitterstruktur 20 weist eine Stärke von etwa 1,5 mm auf und definiert eine Vielzahl von Verdunstungsöffnungen 22, die durch Stege 24 der Gitterstruktur 20 begrenzt sind. Die Verdunstungsöffnungen 22 weisen jeweils einen hexagonalen Querschnitt auf. Dabei beträgt die Länge jeder Verdunstungsöffnung 22 in Längsrichtung des Helms 10 gesehen etwa 4 mm, während die maximale Breite etwa 1,3 mm beträgt.In each of these three ventilation openings 16, an evaporative cooler 18 is used, which is formed in the illustrated embodiment by a rigid grating structure 20. Each grid structure 20 has a thickness of about 1.5 mm and defines a plurality of evaporation openings 22, which are bounded by webs 24 of the lattice structure 20. The evaporation openings 22 each have a hexagonal cross-section. In this case, the length of each evaporation opening 22 seen in the longitudinal direction of the helmet 10 is about 4 mm, while the maximum width is about 1.3 mm.

Bei dieser Dimensionierung der Verdunstungsöffnungen 22 kann ein die Gitterstruktur 20 benetzender Wasserfilm aufgrund seiner Oberflächenspannung auch die Verdunstungsöffnungen 22 überspannen, wenn die Gitterstruktur 20 während der Fahrt, zum Beispiel durch den Helmträger, mit Wasser, beispielsweise aus einer Trinkflasche, übergossen oder bespritzt wird. Infolge der, nicht zuletzt durch den Fahrtwind begünstigten, Trocknung und Verdunstung des Wassers wird eine zusätzliche Kühlung im hinteren Bereich 14 des Helms 10 erreicht, welche den Tragekomfort des Helms 10 deutlich erhöht.With this dimensioning of the evaporation openings 22, a water film wetting the lattice structure 20 can also span the evaporation openings 22 due to its surface tension when the lattice structure 20 is doused or sprayed with water during travel, for example through the helmet wearer, for example from a drinking bottle. As a result of, not least Favored by the wind, drying and evaporation of water additional cooling in the rear portion 14 of the helmet 10 is achieved, which significantly increases the comfort of the helmet 10.
