Abstract

Description

INDIKATOR, SENSOR, VORRICHTUNGEN FÜR DIE QUALITATIVE UND/ODER QUANTITATIVE BESTIMMUNG VON TUBELESS FLÜSSIGKEIT (DICHTMILCH) DIE IN TUBELESS SYSTEMEN EINGEFÜLLT IST, WIE RÄDER, REIFEN, FELGEN INDICATOR, SENSOR, DEVICES FOR THE QUALITATIVE AND/OR QUANTITATIVE DETERMINATION OF TUBELESS FLUID (SEALING MILK) FILLED IN TUBELESS SYSTEMS SUCH AS WHEELS, TIRES, RIMS
Beispielsweise moderne Fahrräder wie Mountainbikes, Rennräder und E Bikes werden zunehmend häufig mit Schlauchlos-Systemen „tubeless" gefahren. Gerade im Mountainbike-bereich können so leichtere Reifen mit weniger Rollwiderstand und/oder reduziertem Luftdruck (mehr Grip) gefahren werden, da zum einen „Snakebites" in Schläuchen (nicht mehr vorhanden) vermieden werden zum anderen können gerade kleinere Stiche und Schnitte im Reifen von vom Dichtmittel bevorzugt der Dichtmilch sofort elegant während der Fahrt abgedichtet werden und ohne Panne weitergefahren werden. Je nach Zusammensetzung der Dichtmilch der diversen Fiersteller (zB Schwalbe®, Continental®, Tune®, Stans®, el3®), Einsatz, Umgebungstemperatur und Abdichtungsfähigkeit schwankt die FHaltbarkeit bis das Dichtmittel z.B. = die Milch die verbraucht / eingetrocknet ist zwischen 1 bis 9 Monaten. Ist die Milch verbraucht ist die Pannengefahr groß. Füllt man zu oft nach, erhöht sich das Gewicht und For example, modern bicycles such as mountain bikes, racing bikes and e-bikes are increasingly being ridden with tubeless systems. Especially in the mountain bike sector, lighter tires with less rolling resistance and/or reduced air pressure (more grip) can be ridden, because on the one hand "Snakebites" in tubes (no longer available) can be avoided, on the other hand, smaller punctures and cuts in the tire can be immediately and elegantly sealed with the sealant, preferably the sealing milk, while driving and you can continue driving without a breakdown. Depending on the composition of the sealing milk of the various sealants (e.g. Schwalbe ® , Continental ® , Tune ® , Stans ® , el3 ® ), use, ambient temperature and sealing ability, the durability varies between 1 and 9 months. If the milk is used up, the risk of breakdown is high. If you refill too often, the weight increases and
Rollwiderstand unnötig. Der Zustand der Dichtmilch ist von außen nicht erkennbar. Die regelmäßige Demontage des Reifens ist unzweckmäßig & aufwändig und meistens eine „große Schweinerei" (falls noch flüssige Dichtmich vorhanden). rolling resistance unnecessary. The condition of the sealing milk cannot be seen from the outside. The regular dismantling of the tire is inexpedient & time-consuming and usually a "big mess" (if liquid sealant is still available).
Der Fiersteller Milkit® hat ein spezielles Ventilsystem entwickelt mit dem die Dichtmilch durchThe Fiersteller Milkit ® has developed a special valve system with which the sealant can flow through
Einführen eines Applikators in das Spezialventil in Verbindung mit Absaugen und wiederInserting an applicator into the special valve in conjunction with suction and again
Einfüllen extern vermessen und nachgefüllt werden kann (https://milkit.bike/de/product/milkit- valvesystem). Aufgabe ist es nun ein einfaches System zu entwickeln was den Dichtmilchzustand von außen anzeigt und darauf hinweist wann Dichtmilch nachzufüllen ist, ohne irgendwelche Messungen wie zB bei Milkit® per Hand oder (De)Montagen durchführen zu müssen: can be measured externally and refilled (https://milkit.bike/de/product/milkit- valvesystem). The task now is to develop a simple system that displays the condition of the sealing milk from the outside and indicates when sealing milk needs to be refilled, without having to carry out any measurements by hand or (dis)assembly, such as with Milkit ® :
Die vorliegende Erfindung beschreibt nun ein für die Praxis an Fahrrädern, E-bikes oder Pedelecs insbesondere mechanisch oder elektrisch angetriebene Rennräder, Crossbikes & Mountainbike taugliches und einfaches System, bei dem an der Felge zum einen StandardTubeLessVentile verwendet können und zum anderen keinerlei Eingriffe oder Flüssigkeitsvermessungen durch zB mechanische Pipetten, Schläuche weder innerhalb noch außerhalb des Reifens notwendig sind. Unter Standardtubelessventil werden bevorzugt alle Ventile verstanden die zur Benutzung von tubeless Milch geeignet sind bevorzugt mit herausnehmabren Ventilkern zB bevorzugt die auch mit tube verwendeten französischen Ventile . The present invention now describes a simple system that is suitable for use on bicycles, e-bikes or pedelecs, in particular mechanically or electrically driven racing bikes, cross bikes and mountain bikes, in which on the one hand standard tubeless valves can be used on the rim and on the other hand no interventions or liquid measurements are required eg mechanical pipettes, hoses are not necessary inside or outside the tire. A standard tubeless valve is preferably understood to mean all valves that are suitable for the use of tubeless milk, preferably with a removable valve core, for example, preferably the French valves also used with a tube.
Natürlich kann die Vorrichtung und oder das System auch an anderen Reifen verwendet werden, bevorzugt Luftreifen, zB bei Autos, Flugzeugen und sonstigen Fahrzeugen und / oder Gefährten.Of course, the device and/or the system can also be used on other tires, preferably pneumatic tires, for example on cars, airplanes and other vehicles and/or companions.
Die Lösung dieser technischen Aufgabe wird verwirklicht durch Bereitstellung eines The solution to this technical problem is realized by providing a
Systems und/oder Indikators und oder Sensors der zB auf Feuchtigkeit (beispielsweise ca. 20-60 % Systems and/or indicators and/or sensors, for example for moisture (e.g. approx. 20-60%
Wasseranteil in üblichen Dichtmilchzusammensetzungen) und/oder andere Bestandteile der Water content in conventional sealing milk compositions) and / or other components of
Dichtmilch reagiert und / oder diese vermisst. Sealant reacts and / or misses it.
In der Regel wird das Dichtmittel eine Dichtmilch sein und/oder einfach in einen Reifen eingefüllt sein und sich im flüssigen Zustand befinden und sich im Reifen verteilen. Typically, the sealant will be a sealant and/or simply poured into a tire and will be in the liquid state and distributed throughout the tire.
Die Messung kann qualitativ oder quantitativ erfolgen. Ein Gegenstand ist eine qualitative Messung ob Dichtmittel vorhanden ist oder nicht; zB über eine chemische oder physikalische Reaktion eines Indikators. Ein weiterer Gegenstand ist eine quantitative Messung zB über einen Sensor. The measurement can be qualitative or quantitative. An item is a qualitative measurement of whether sealant is present or not; eg via a chemical or physical reaction of a indicator. Another subject is a quantitative measurement, for example using a sensor.
Bsp für bevorzugte Ausgestaltungen: Dies könnte zB im einfachsten Fall durch ein kleines durchsichtiges Sichtfenster bevorzugt aus Kunststoff an der Felge oder bevorzugt des Reifens sehr bevorzugt auf der Reifenflanke oder Reifenlauffläche verwirklicht sein (mit dem die Dichtmilch inspiziert werden kann), noch bevorzugter ist aber ein Sichtfenster bevorzugt aus Kunststoff bei dem auf der Innenseite des Sichtfenster (also auf der Reifen- oder Felgeninnenseite) ein zB auf Feuchtigkeit reagierendes Material aufgetragen ist, das zB ähnlich wie bei Silicagel mit einem Farbumschlag signalisiert wenn der Feuchtigkeitsgehalt reduziert wird (d.h. die Dichtmilch eintrocknet und nachgefüllt werden muss). Bevorzugte Materialen als Innenschicht oder eingearbeitet in den Laufradinneren Teil des Kunststoffs sind u.a. eine Silicagelschicht mit Cobaltdichlorid, Cobaltdichlorid, Silicagelschicht mit Methylviolett, Methylviolett oder ähnliche auf Feuchtigkeit oder auf andere Komponenten der Dichtmilch reagierende Chemikalien und / oder Sensoren. So schlägt CoCI2 von rot nach blau um und Methylviolett von grün nach orange. Diese innen beschichteten kleinen durchsichtigen Kunststofffenster können einfach in die Felge oder den Gummi des Reifens in der Fertigung integriert werden. Bereits vorgefertigte (für andere Zwecke zB Transport entwickelte ) reversible Feuchtigkeitsindikatoren sind im Flandel erhältlich.

Example of preferred configurations: In the simplest case, this could be realized, for example, by a small transparent viewing window, preferably made of plastic, on the rim or preferably the tire, very preferably on the tire sidewall or tire tread (with which the sealant can be inspected), but even more preferred is a Viewing window preferably made of plastic in which a material that reacts to moisture is applied to the inside of the viewing window (i.e. on the inside of the tire or rim), which, for example, similar to silica gel with a color change, signals when the moisture content is reduced (i.e. the sealant dries and must be refilled). Preferred materials as the inner layer or incorporated into the impeller inner part of the plastic include a silica gel layer with cobalt dichloride, cobalt dichloride, silica gel layer with methyl violet, methyl violet or similar chemicals and/or sensors that react to moisture or other components of the sealant. CoCl2 changes from red to blue and methyl violet from green to orange. These small, transparent plastic windows are coated on the inside and can easily be integrated into the rim or the rubber of the tire during production. Ready-made reversible moisture indicators (developed for other purposes, e.g. transport) are available in Flandel. E.g. www.transportcontrol.de https://transportcontrol.de/index.php/produktuebersicht/temperatur- und-Humidity-Indicators ). Alternative ecological embodiments would be systems from Propagroup (https://www.propagroup.de/de/prod-159/Humidity-undtemperature-display/propasecard-humidity-indicators-without-kobalt-dichloride).

Further embodiments that can be used for signaling would include electronic, electromagnetic, radio wave-based or electrical miniature moisture measurement sensors on the inside of the tire or rim or on the inner ring of the valve or inside the valve. These sensors can be in the form of a mini RFID chip, for example. The data “Humidity is below
