Definitions
- the invention relates to a protective helmet for motorcyclists or the like of the type mentioned in the preamble of claim 1, which is generally known.
- a motorcyclist usually keeps his head tilted more or less deeply at different vehicle speeds for aerodynamic or habitual reasons, whereby of course his protective helmet also takes on correspondingly different inclinations.
- his protective helmet also takes on correspondingly different inclinations.
- this results in changed air flow angles on the protective helmet and thus different sized air resistances.
- the air flow acting on the rear of the helmet tears off considerably below the highest helmet curvature area, as a result of which an air flow flowing over the rear of the helmet and towards the lower edge of the helmet has been formed.
- the object of the invention is therefore to design a protective helmet of the type mentioned at the outset with simple means in such a way that the air may stall in the area of the greatest helmet width largely independently of the particular head posture of the motorcyclist.
- the air flow acting on the protective helmet at its upper area is separated at the highest curvature area of the helmet tip, that is to say in the area of an inflow direction which is approximately tangential to the latter.
- This air flow which flows approximately horizontally due to the designs according to the invention, is combined with the air flow flowing obliquely up and back over the shoulders of the motorcyclist and with the air flow flowing up the back of the motorcycle in the area of the helmet tip - the individual air flows acting as "force vectors" to a certain extent, so that the neck area of the motorcycle rider is relieved of the wind pressure comparatively considerably by the confluence of the air currents, which is shifted towards the top of the helmet.
- a very expedient embodiment of the invention consists (feature of claim 2) of forming the elevations and / or depressions as transverse ribs or transverse grooves which run transversely or obliquely to the direction of flow. These can also be arrow-shaped, where they converge in the area of the helmet symmetry plane.
- transverse ribs and transverse grooves have a sinusoidal cross-sectional profile (feature of claim 3).
- the helmet surface can also be roughened in the area of the helmet tip by a plurality of approximately hemispherical knobs (feature of claims 8 and 9) or even only with an irregular surface structure, which is formed, for example, by a large number of grains.
- the motorcycle driver's protective helmet 1 shown in FIG. 1 is designed as an integral helmet and has a viewing opening 2 which can be covered by a viewing window 3. This is mounted on two bearing bolts 4 engaging in the helmet shell 10 so that they can be swiveled up and down.
- the protective helmet 1 has in the area of the helmet tip 6 a number of elevations and / or depressions which protrude beyond the helmet surface 10 'or are set back from it.
- the elevations each consist of transverse ribs 7, while the depressions shown to the left of the break line are each designed as transverse grooves 8; grooves 70 are formed between the transverse ribs 7, while webs 80 each remain between the transverse grooves 8.
- transverse ribs 7 projecting only slightly beyond the helmet surface 10 ′ can also be provided with transverse grooves 8 set back from it.
- transverse ribs 7 and / or transverse grooves 8 extend transversely or obliquely to the inflow direction a and extend over the helmet tip 6 to approximately in the region of the upper edge 2 'of the viewing opening 2. It is also conceivable that the transverse ribs 7 and / or transverse grooves 8 each run in an arrow shape, where they converge in a plan view of the helmet tip 6 in the area of the helmet symmetry plane.
- the transverse ribs 7 and transverse grooves 8 each have a rectangular cross-sectional profile, their height b being approximately 1-2 mm, while their width c measuring approximately 4-8 mm; the grooves 70 formed between the transverse ribs 7 and webs 80 remaining between the transverse grooves 8 each have approximately the same cross-sectional profile of the transverse ribs 7 and transverse grooves 8.
- the Cross ribs 7 and cross grooves 8 for example, also have a trapezoidal or ridge-shaped cross-sectional profile.
- the transverse ribs 7 'and transverse grooves 8' can also have a sinusoidal cross-sectional profile.
- the individual waves have a height b 'of approximately 0.25-1.5 mm, while the wavelength d is approximately 1-50 mm.
- the transverse ribs 7 and 7 ' can also be designed in sections.
- One transverse rib section expediently covers a gap in the adjacent row of transverse ribs 7, 7 '.
- a plurality of approximately hemispherical knobs which have a diameter of approximately 1-14 mm and a height of approximately 0.5-2 mm, can also protrude from the helmet surface 10 'in the area of the helmet tip 6.
- the individual knobs are arranged in rows and at the same distance from each other, the individual rows of knobs running transversely or obliquely to the direction of flow a.
- the knobs of a row are expediently each in a gap with the knobs of the adjacent row of knobs.
- transverse ribs 7 and 7 'or transverse grooves 8 and 8' or the rows of knobs are set back by the dimension e, which is approximately 50-80 mm, from the upper edge 2 'of the viewing opening 2 and extend over the helmet tip 6 over an angular range ⁇ -60 ° -100 °.
- the air flow acting on the protective helmet 1 in the region of the helmet tip 6 becomes independent of the respective inclination position of the protective helmet 1 in the one designated by f Area - if not already in front of this - is separated and continues to flow behind the protective helmet 1 approximately horizontally, as illustrated by the arrows labeled a '.
Abstract
Description
Die Erfindung bezieht sich auf einen Schutzhelm für Motorradfahrer oder dergleichen der im Oberbegriff des Patentanspruchs 1 genannten Art, welche allgemein bekannt ist.The invention relates to a protective helmet for motorcyclists or the like of the type mentioned in the preamble of claim 1, which is generally known.
Ein Motorradfahrer hält üblicherweise seinen Kopf bei unterschiedlich hohen Fahrzeuggeschwindigkeiten aus aerodynamischen oder gewohnheitsmäßigen Gründen mehr oder weniger tief geneigt, wobei natürlich auch sein Schutzhelm entsprechend unterschiedliche Neigungslagen einnimmt. Durch diese ergeben sich jedoch veränderte Luftanströmwinkel auf den Schutzhelm und dadurch unterschiedlich große Luftwiderstände. Insbesondere bei einer stark geneigten Kopfhaltung des Motorradfahrers reißt wegen der glatten Helmoberfläche eines allgemein bekannten Motorradfahrer-Schutzhelms der diesen beaufschlagende Luftstrom an der Helmrückseite erheblich unterhalb des höchsten Helmkrümmungsbereichs ab, wodurch sich erwiesenermaßen eine über die Helmrückseite, zum unteren Helmrand hin fließende Luftströmung bildet. Da diese sowohl mit einem über den Rücken des Motorradfahreres zu seinem Hals hin hochströmenden als auch mit einem über dessen Schultern schräg nach oben und hinten strömenden Luftstrom zusammentrifft, entsteht im Halsbereich des Motorradfahrers durch Luftwirbel und Querströmungen ein seinen Hals stark belastender Winddruck, was insbesondere während einer längeren Motorradfahrt stark ermüdend wirkt.A motorcyclist usually keeps his head tilted more or less deeply at different vehicle speeds for aerodynamic or habitual reasons, whereby of course his protective helmet also takes on correspondingly different inclinations. However, this results in changed air flow angles on the protective helmet and thus different sized air resistances. Especially in the case of a heavily inclined head posture of the motorcycle rider, due to the smooth helmet surface of a well-known motorcycle rider protective helmet, the air flow acting on the rear of the helmet tears off considerably below the highest helmet curvature area, as a result of which an air flow flowing over the rear of the helmet and towards the lower edge of the helmet has been formed. Since this coincides with an airflow flowing over the back of the motorcyclist to his neck as well as with an airflow that flows obliquely upwards and backwards over his shoulders, wind turbulence and cross currents in the neck area of the motorcyclist create a strong wind pressure on his neck, which is particularly tiring during a long motorcycle ride.
Aufgabe der Erfindung ist es daher, einen Schutzhelm der eingangs genannten Gattung mit einfachen Mitteln derart auszubilden, daß weitgehend unabhängig von der jeweiligen Kopfhaltung des Motorradfahrers ein Strömungsabriß der Luft im Bereich der größten Helmbreite entstehen kann.The object of the invention is therefore to design a protective helmet of the type mentioned at the outset with simple means in such a way that the air may stall in the area of the greatest helmet width largely independently of the particular head posture of the motorcyclist.
Zur Lösung der Aufgabe sind die im kennzeichnenden Teil des Patentanspruchs 1 dargelegten Gestaltungsmerkmale vorgesehen.To achieve the object, the design features set out in the characterizing part of claim 1 are provided.
Durch die an der Helmkuppe vorgesehenen Erhöhungen und/ oder Vertiefungen wird der den Schutzhelm an seinem oberen Bereich beaufschlagende Luftstrom am höchsten Krümmungsbereich der Helmkuppe, also im Bereich einer zu letzterer etwa tangential verlaufenden Anströmrichtung, abgetrennt. Dieser, durch die erfindungsgemäßen Ausbildungen etwa waagrecht fließende Luftstrom vereinigt sich mit dem über die Schultern des Motorradfahrers schräg nach oben und hinten fließenden sowie mit dem über dessen Rücken hochströmenden Luftstrom im Bereich der Helmkuppe - wobei die einzelnen Luftströme gewissermaßen als "Kraftvektoren" wirken - , so daß der Halsbereich des Motorradfahrers durch den aufwärts, zur Helmkuppe hin verlagerten Zusammenfluß der Luftströme vergleichsweise erheblich vom Winddruck entlastet wird. Hierdurch werden Ermüdungen im Halsbereich des Motorradfahrers vor allem im mittleren Geschwindigkeitsbereich (120-140 km/h) wesentlich verringert. Ferner können dabei auchDauerhöchstgeschwindigkeiten wesentlich gesteigert werden. Durch die erfindungsgemäß vorgesehenen Erhebungen und/oder Vertiefungen an der Helmkuppe ist ferner der Luftwiderstand in allen Fahrpositionen und den sich dadurch ergebenden unterschiedlichen Kopfhaltungen des Motorradfahrers, also auch bei Motorräder mit Rennlenkern oder Tourenlenkern, weitgehend gleichgroß. Die Vertiefungen und/oder Erhöhungen können vorteilhafterweise praktisch ohne zusätzliche Kosten bei Neuanfertigung eines Schutzhelms vorgesehen werden. Schließlich sind auch Erhöhungen an einem vorhandenen Schutzhelm mit geringem Kostenaufwand nachrüstbar.By means of the elevations and / or depressions provided on the helmet tip, the air flow acting on the protective helmet at its upper area is separated at the highest curvature area of the helmet tip, that is to say in the area of an inflow direction which is approximately tangential to the latter. This air flow, which flows approximately horizontally due to the designs according to the invention, is combined with the air flow flowing obliquely up and back over the shoulders of the motorcyclist and with the air flow flowing up the back of the motorcycle in the area of the helmet tip - the individual air flows acting as "force vectors" to a certain extent, so that the neck area of the motorcycle rider is relieved of the wind pressure comparatively considerably by the confluence of the air currents, which is shifted towards the top of the helmet. This significantly reduces fatigue in the motorcycle rider's neck area, especially in the medium speed range (120-140 km / h). Furthermore, top speeds can also be increased significantly. Due to the elevations and / or depressions provided on the helmet tip according to the invention, the air resistance in all driving positions and the resulting different head positions of the motorcycle rider is also for motorcycles with racing handlebars or touring handlebars, largely the same size. The depressions and / or elevations can advantageously be provided practically without additional costs when a protective helmet is manufactured. Finally, increases on an existing safety helmet can be retrofitted at low cost.
Eine sehr zweckmäßige Ausgestaltung der Erfindung besteht darin (Merkmal des Patentanspruchs 2), die Erhöhungen und/oder Vertiefungen als Querrippen bzw. Querrillen auszubilden, die quer oder auch schräg zur Anströmrichtung verlaufen. Diese können auch pfeilförmig ausgebildet sein, wobei sie im Bereich der Helmsymmetrieebene zusammenlaufen.A very expedient embodiment of the invention consists (feature of claim 2) of forming the elevations and / or depressions as transverse ribs or transverse grooves which run transversely or obliquely to the direction of flow. These can also be arrow-shaped, where they converge in the area of the helmet symmetry plane.
Ferner ist es auch denkbar, daß die Querrippen und Querrillen ein sinusförmiges Querschnittsprofil haben (Merkmal des Patentanspruchs 3).Furthermore, it is also conceivable that the transverse ribs and transverse grooves have a sinusoidal cross-sectional profile (feature of claim 3).
Die Helmoberfläche kann im Bereich der Helmkuppe darüber hinaus auch durch eine Vielzahl von etwa halbkugelförmigen Noppen angerauht werden (Merkmal der Patentansprüche 8 und 9) oder auch lediglich mit einer unregelmäßigen Oberflächenstruktur, welche z.B.durch eine Vielzahl von Körnern gebildet wird, versehen ist.The helmet surface can also be roughened in the area of the helmet tip by a plurality of approximately hemispherical knobs (feature of claims 8 and 9) or even only with an irregular surface structure, which is formed, for example, by a large number of grains.
Weitere Ausgestaltungen der Erfindung sind in anderen Unteransprüchen gekennzeichnet.Further embodiments of the invention are characterized in other subclaims.
Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt und werden im folgenden erläutert. Es zeigt:
- Fig. 1 einen Motorradfahrer-Schutzhelm mit im Bereich seiner Kuppe vorgesehenen Querrippen und Querrillen,
- Fig. 2 ein sinusförmiges Querschnittsprofil der Querrippen und Querrillen in größerem Maßstab.
- 1 a motorcycle rider hard hat with transverse ribs and transverse grooves provided in the area of his crest,
- Fig. 2 is a sinusoidal cross-sectional profile of the transverse ribs and transverse grooves on a larger scale.
Der in Fig. 1 dargestellte Motorradfahrer-Schutzhelm 1 ist als ein Integralhelm gestaltet und weist eine Sichtöffnung 2 auf, welche von einer Sichtscheibe 3 überdeckbar ist. Diese ist an zwei in die Helmschale 10 eingreifenden Lagerbolzen 4 hoch- und niederschwenkbar gelagert.The motorcycle driver's protective helmet 1 shown in FIG. 1 is designed as an integral helmet and has a
Der Schutzhelm 1 hat im Bereich der Helmkuppe 6 eine Anzahl von Erhebungen und/oder Vertiefungen, welche über die Helmoberfläche 10' hinausragen bzw. von dieser zurückgesetzt sind. Wie in Fig. 1 rechts von der Bruchlinie veranschaulicht, bestehen die Erhebungen jeweils aus Querrippen 7, während die links von der Bruchlinie dargestellten Vertiefungen jeweils als Querrillen 8 ausgebildet sind; dabei sind zwischen den Querrippen 7 jeweils Nuten 70 gebildet, während zwischen den Querrillen 8 jeweils Stege 80 verbleiben. Natürlich können auch nur geringfügig über die Helmoberfläche 10' hinausragende Querrippen 7 bei dabei von dieser zurückgesetzten Querrillen 8 vorgesehen werden. Die Querrippen 7 und/oder Querrillen 8 erstrecken sich quer oder auch schräg zur Anströmrichtung a und verlaufen über die Helmkuppe 6 bis etwa in den Bereich der Oberkante 2' der Sichtöffnung 2. Es ist auch denkbar, daß die Querrippen 7 und/oder Querrillen 8 jeweils pfeilförmig verlaufen, wobei sie in Draufsicht auf die Helmkuppe 6 im Bereich der Helmsymmetrieebene zusammenlaufen.The protective helmet 1 has in the area of the helmet tip 6 a number of elevations and / or depressions which protrude beyond the helmet surface 10 'or are set back from it. As illustrated in FIG. 1 to the right of the break line, the elevations each consist of
Bei dem in Fig. 1 veranschaulichten Ausführungsbeispiel haben die Querrippen 7 und Querrillen 8 jeweils ein rechteckförmiges Querschnittsprofil, wobei ihre Höhe b etwa 1-2 mm beträgt, während ihre Breite c etwa 4-8 mm mißt; die zwischen den Querrippen 7 gebildeten Nuten 70 und zwischen den Querrillen 8 verbleibenden Stege 80 haben jeweils etwa das gleichgroße Querschnittsprofil der Querrippen 7 und Querrillen 8. Natürlich können die Querrippen 7 und Querrillen 8 beispielsweise auch ein trapez- oder firstförmiges Querschnittsprofil aufweisen.In the exemplary embodiment illustrated in FIG. 1, the
Wie in Fig. 2 ersichtlich, können die Querrippen 7' und Querrillen 8' auch ein sinusförmiges Querschnittsprofil aufweisen. Dabei haben die einzelnen Wellen eine Höhe b' von etwa 0,25-1,5 mmm, während die Wellenlänge d etwa 1- 50 mm beträgt.As can be seen in FIG. 2, the transverse ribs 7 'and transverse grooves 8' can also have a sinusoidal cross-sectional profile. The individual waves have a height b 'of approximately 0.25-1.5 mm, while the wavelength d is approximately 1-50 mm.
Damit der an die Helmkuppe 6 anströmende Luftstrom in deren Bereich optimal und durch die vorgesehenen Querrippen 7,7'und Querrillen 8,8'abgerissen wird, können die Querrippen 7 und 7' auch abschnittsweise ausgebildet sein.' Dabei überdeckt zweckmäßigerweise jeweils ein Querrippenabschnitt eine Lücke der benachbart verlaufenden Reihe von Querrippen7,7'.So that the air flow flowing to the
Nach einem weiteren, nicht gezeichneten Ausführungsbeispiel können von der Helmoberfläche 10' im Bereich der Helmkuppe 6 auch eine Vielzahl von etwa halbkugelförmigen Noppen abstehen, die einen Durchmesser von etwa 1-14 mm und eine Höhe von etw a 0,5-2 mm haben. Dabei sind die einzelnen Noppen reihenartig und in gleichgroßem Abstand nebeneinanderliegend angeordnet, wobei die einzelnen Noppenreihen quer oder auch schräg zur Anströmrichtung a verlaufen. Zweckmäßigerweise befinden sich dabei die Noppen einer Reihe jeweils auf Lücke zu den Noppen der benachbart verlaufenden Reihe von Noppen.According to a further exemplary embodiment, not shown, a plurality of approximately hemispherical knobs, which have a diameter of approximately 1-14 mm and a height of approximately 0.5-2 mm, can also protrude from the helmet surface 10 'in the area of the
Die Querrippen 7 und 7' oder Querrillen 8 und 8' bzw. die Noppenreihen sind um das Maß e, das etwa 50-80 mm beträgt, von der Oberkante 2' der Sichtöffnung 2 zurückgesetzt und erstrecken sich über die Helmkuppe 6 über einen Winkelbereich α-60°-100°.The
Durch die erfindungsgemäß an der Helmkuppel 6 vorgesehenen Querrippen 7, 7' und Querrillen 8, 8' bzw. durch die halbkugelförmigen Noppen wird der den Schutzhelm 1 im Bereich der Helmkuppe 6 beaufschlagende Luftstrom unabhängig von der jeweiligen Neigungslage des Schutzhelm 1 in dem mit f bezeichneten Bereich - wenn nicht bereits vor diesem - abgetrennt und fließt hinter dem Schutzhelm 1 etwa waagrecht verlaufend weiter, wie die mit a' bezeichneten Pfeile veranschaulichen.By means of the
