Description

Die vorliegende Erfindung bezieht sich auf einen Ski-, Fahrrad-, E-Bike-, Flugsport- und Kletterhelm, zerlegbar durch einen Rotations-Translationsmechanismus, unterstützt von einem Verriegelungs-/Entriegelungssystem. Insbesondere erlaubt der Rotations- Translationsmechanismus, das Volumen eines Ski-, Fahrrad-, E-Bike-, Flugsport- und Kletterhelmes zu verkleinern, um ihn leichter in einer Tragtasche oder Rucksack oder Handkoffer dank einer seiner Verkleinerung des gesamten Volumens ablegen zu können.The present invention relates to a ski, bicycle, e-bike, aviation and climbing helmet, which can be dismantled by a rotation translation mechanism, supported by a locking / unlocking system. In particular, the rotation-translation mechanism allows the volume of a ski, bicycle, e-bike, aviation and climbing helmet to be reduced in order to be able to store it more easily in a carrier bag or backpack or suitcase thanks to one of its reduction in the total volume.

Der Rotations-Translationsmechanismus besteht aus einem innerhalb einer Polystyrolstruktur befestigten Aufnahmegehäuse aus Kunststoff, die ein erstes Helmteil bildet, während ein Band mit Langloch innerhalb einer Polystyrolstruktur befestigt ist, die ein zweites Helmteil bildet; das Band mit Langloch, immer aus Kunststoff, wird auf einem Kunststoffbolzen geschwenkt bzw. gedreht wird, der bündig am Aufnahmegehäuse befestigt ist.The rotary translation mechanism consists of a plastic housing housing fastened within a polystyrene structure, which forms a first helmet part, while a band with an elongated hole is fastened within a polystyrene structure, which forms a second helmet part; the band with an elongated hole, always made of plastic, is swiveled or rotated on a plastic bolt that is attached flush to the receiving housing.

Das zweite Teil des Ski-, Fahrrad-, E-Bike-, Flugsport- und Kletterhelmes, das seinem hinteren Abschnitt entspricht, wirkt mit dem ersten vorne angeordneten Teil zusammen, dank eines im oberen Teil angeordneten Verriegelungs- /Entriegelungsmechanismus, wo ein Zahnband/Zahnriemen aus Kunststoff befestigt ist, das auf einer am ersten Teil befestigten Verriegelungs-/Entriegelungsdrucktaste, immer aus Kunststoff, eingreift.The second part of the ski, bicycle, e-bike, aviation and climbing helmet, which corresponds to its rear section, interacts with the first part arranged in front thanks to a locking / unlocking mechanism arranged in the upper part, where a toothed belt / Timing belt is made of plastic, which engages on a locking / unlocking push button attached to the first part, always made of plastic.

Auf dem Markt bestehen einige zerlegbare Heldenmodelle für Sport wie Ski, Snowboard, Radfahren und E-Bike.There are some demountable hero models on the market for sports such as skiing, snowboarding, cycling and e-biking.

Es wird auf das Modell OVERADE® hingewiesen, das mit einem Außenrahmen aus dem Polystyrol zugeordneten Kunststoff aufgebaut ist, der durch einen "V" Knickmechanismus und einen Drehbolzen dem genannten Hinterteil erlaubt sich zu verkleinern und innerhalb dem vorderen Teil einzufügen, wobei so das Gesamtvolumen reduziert wird. Diese Helmart ist jedoch sehr schwer, da sie mit einem Außenrahmen aus Plastik und mit verschiedenen, unterschiedliche aus Metall gebildeten Mechanismen ausgeführt ist, und daher wenig zweckdienlich für Sport wie Skisport ist, wo leichte Schutzzubehöre gesucht werden.Attention is drawn to the OVERADE® model, which is constructed with an outer frame made of the plastic assigned to polystyrene, which allows the rear part to be reduced in size and inserted within the front part by means of a "V" folding mechanism and a pivot pin, thus reducing the overall volume becomes. However, this type of helmet is very heavy, since it is made with an outer frame made of plastic and with different mechanisms made of metal, and is therefore not very useful for sports such as skiing, where light protective accessories are sought.

Ein weiterer Helm, der sein Volumen verkleinert, wo drei ihn bildende Silikonringe vertikal "gequetscht werden", ist jener von der spanischen Closca Design® vorgeschlagene, der nur für E-Bike Benutzer vorgesehen und nicht für sportliche Tätigkeiten, wie Ski, Fahrrad, Flugsport und Klettern zugelassen ist.Another helmet that reduces its volume, where three silicone rings forming it are "squeezed" vertically, is the one proposed by the Spanish Closca Design®, which is only intended for e-bike users and not for sporting activities such as skiing, cycling, aviation and climbing is allowed.

Auf dem Markt befindet sich noch ein weiterer Fahrrad- und E-Bike-Helm, der sein Volumen dank eines Plastikmechanismus und Metallkomponenten reduziert, die den Helm transversal in 2 Teile teilen; da der Helm oberhalb des Polystyrols einen Plastikrahmen aufweist, ist derselbe schwer und für sportliche Tätigkeiten wie Ski, Sportflug und Klettern nicht zugelassen.There is another bicycle and e-bike helmet on the market that reduces its volume thanks to a plastic mechanism and metal components that transversely divide the helmet into two parts; since the helmet has a plastic frame above the polystyrene, it is heavy and not approved for sports such as skiing, sports flying and climbing.

Unter Bezugnahme auf die erwähnten Figuren, besteht der zerlegbare Helm 100 aus einem vorderen Teil in Polystyrol 101, mit oder ohne ästhetischer Bedeckung 101A, aus einem hinteren Teil in Polystyrol 102, mit oder ohne ästhetischer Bedeckung 102A, aus einem Schutz mit Ohren 103 und aus einem entsprechenden Riemchen 104. Innerhalb des vorderen Teils 101 ist ein Aufnahmegehäuse 205 mit einer Endanschlagskugel 207 befestigt, die durch eine Feder 209 beaufschlagt ist. Immer im vorderen Teil ist das Aufnahmegehäuse des Verriegelungs- /Entriegelungssystems 300 mit der in seinem Inneren angeordneten Drucktaste 301 befestigt, die dank der Federn 302 vertikal wirkt.With reference to the figures mentioned, the demountable helmet 100 consists of a front part in polystyrene 101, with or without aesthetic covering 101A, a rear part in polystyrene 102, with or without aesthetic covering 102A, a protection with ears 103 and a corresponding strap 104. Inside the front part 101, a receiving housing 205 is fastened with an end stop ball 207 which is acted upon by a spring 209. The receiving housing of the locking / unlocking system 300 is always fastened in the front part with the push button 301 arranged in its interior, which acts vertically thanks to the springs 302.

Innerhalb des hinteren Teils 102 und in oberer Stellung ist ein Zahnband 310 befestigt, das mit der Drucktaste 301 zusammenwirkt und die Verriegelung/Entriegelung der 2 Helmteile 100 ermöglicht; im unteren Teil, auf derselben Ebene des Aufnahmegehäuses 205, ist ein Band 210 mit Langloch 211 vorhanden, das am Aufnahmegehäuse 205 über einen Bolzen 201 zusammenwirkt, wobei so die Schwenkung des oberen Teils des Helmes 102 und die Ausführung der Rotations-Translationsquerbewegungen erlaubt wird.A toothed belt 310 is fastened within the rear part 102 and in the upper position, which interacts with the push button 301 and enables the locking / unlocking of the 2 helmet parts 100; in the lower part, on the same level of the receiving housing 205, there is a band 210 with an elongated hole 211 which cooperates on the receiving housing 205 via a bolt 201, thus permitting the swiveling of the upper part of the helmet 102 and the execution of the rotational translational transverse movements.

Der Benutzer, der das Volumen des zerlegbaren Helmes 100 gemäß der Erfindung reduzieren möchte, muss das obere Teil entriegeln, indem er auf die Drucktaste 301 drückt, die das Zahnband 310 befreit.
