Taschenlampengehäuse und einem Taschenlampenkopf. Ferner betrifft die Flashlight housing and a flashlight head. Furthermore, the
Erfindung ein Verfahren zur Herstellung einer solchen Taschenlampe. Invention a method for producing such a flashlight.
Taschenlampen sind seit etlichen Jahrzehnten in unterschiedlichen Formen und für unterschiedliche Anwendungszwecke bekannt, wobei sich aufgrund der einfachen Ausgestaltung, der kostengünstigen Herstellbarkeit und der gegebenen Stabilität zylinderförmige Taschenlampen der eingangs genannten Art als besonders bevorzugt herausgestellt haben. Neben der Form haben sich Taschenlampen auch in ihren Funktionsmöglichkeiten für unterschiedliche Berufsgruppen erweitert, die an die Taschenlampen unterschiedliche Anforderungen stellen. Bei Berufsgruppen, wie beispielsweise bei Einsatzkräften der Polizei oder der Feuerwehr und insbesondere bei Schaffnern von Bahnunternehmen besteht der Wunsch nach Taschenlampen, die Licht in unterschiedlichen Farben abgeben, um über die Wahl der Farbe mit Kollegen zu kommunizieren. Flashlights have been known for several decades in various forms and for different applications, which have been found to be particularly preferred due to the simple design, the cost-effective manufacturability and the given stability cylindrical flashlights of the type mentioned. In addition to the form flashlights have also been extended in their functional options for different professions, which make different demands on the flashlights. There is a desire among professional groups, such as the police or fire brigade and, in particular, railway company conductors, for flashlights that emit light of different colors to communicate with colleagues about the choice of color.
Aus diesen Gründen sind nach dem Stand der Technik Taschenlampen bekannt, die LED's in unterschiedlichen Farben besitzen und die über einen Drehschalter eingeschaltet werden können. For these reasons, flashlights are known in the prior art, the LEDs have different colors and can be turned on via a rotary switch.
Aus US 7,722,209 B2 ist beispielsweise eine Taschenlampe bekannt, die in unmittelbarer Nähe zum Taschenlampenkopf einen Drehring mit darin angeordneten Magneten besitzt, die mit Hall-Sonden wechselwirken, die innerhalb der From US 7,722,209 B2, for example, a flashlight is known, which has in the immediate vicinity of the flashlight head a rotary ring with magnets arranged therein, which interact with Hall probes, which within the
Taschenlampe angeordnet sind. Je nach der eingestellten angularen Position werden unterschiedliche LED's und mithin unterschiedliche Farben bzw. Intensitäten angesteuert. Flashlight are arranged. Depending on the set angular position different LEDs and therefore different colors or intensities are controlled.
Eine derartige Ausgestaltung eines Drehschalters ist sehr komplex und aufgrund der aufwendigen Bauelemente teuer in der Herstellung. Zudem werden diese Such a configuration of a rotary switch is very complex and expensive to manufacture due to the expensive components. In addition, these are
BESTÄTIGUNGSKOPIE Drehschalter beim robusten Einsatz schnell beschädigt, so dass eine einwandfreie Funktionsfähigkeit über einen langen Zeitraum nicht gewährleistet ist. CONFIRMATION COPY Rotary switch quickly damaged during robust use, so that proper functioning over a long period of time is not guaranteed.
Eine Alternative und dabei robuste und einfache Variante eines Drehschalters wird bei zylinderförmigen Taschenlampen unmittelbar durch Verdrehen des An alternative and yet robust and simple variant of a rotary switch is in cylindrical flashlights directly by turning the
Taschenlampenkopfes oder der Endkappe realisiert, die in der Regel ohnehin über ein Gewinde drehbar mit dem Taschenlampengehäuse verbunden sind. Bei derartigen Druckschaltern überstreicht ein Kontaktelement beim Drehen Flashlight head or the end cap realized, which are usually already connected via a thread rotatably connected to the flashlight housing. In such pressure switches, a contact element sweeps when turning

An example of such a rotary switch is disclosed in WO 2012/006977, according to which the rotary switch is formed by a rotatable ring on the end cap.
Nachteilig an einer solchen Ausführungsform ist jedoch, dass die relative Position der drehbar zueinander angeordneten Kontaktelemente nicht eindeutig ist, sobald die Taschenlampe - beispielsweise zum Austausch der Batterien - auseinandergeschraubt wird. Beim Zusammensetzen ist eine eindeutige angulare Position nicht mehr gegeben, da Gewindeverbindungen in unterschiedlichen A disadvantage of such an embodiment, however, is that the relative position of the rotatably arranged contact elements is not clear as soon as the flashlight - for example, to replace the batteries - is unscrewed. When assembling a unique angular position is no longer given because threaded connections in different
Winkelpositionen zueinander zusammengeschraubt werden können. Im Ergebnis muss die Taschenlampe vor jedem Einsatz eingeschaltet werden, um zu überprüfen, ob die Lampe mit der beabsichtigten und eingestellten Funktion leuchtet. Wird ein derartiger Funktionstest versehentlich nicht durchgeführt, können - je nach Angular positions can be screwed together. As a result, the flashlight must be turned on before each use to verify that the lamp is lit with the intended and set function. If such a bump test is not performed by mistake, depending on
Anwendungsbereich - Missverständnisse oder gar schwere Unfälle verursacht werden, da es nämlich einen großen Unterschied macht, ob beispielsweise ein Schaffner dem Lokführer seines Zuges ein rotes oder ein grünes Signal übermittelt. Scope of application - misunderstandings or even major accidents are caused, because it makes a big difference, for example, whether a conductor transmits a red or a green signal to the driver of his train.
