Since the additional conical shape of the shell inner surface and the connector outer surface is dispensed with, the connector in the axial direction accordingly shallower.
- a hollow-cylindrical component is used for the packaging of a foldable pocket umbrella for the transport state and the use of the umbrella by means of a handle cover / carrying handle.
- some possible construction and connection techniques are proposed for the fixed detachable connection of casing and connector; other connections - such as a bayonet closure with Klipsung or detent - can also be considered.
- other, non-cylindrical or semi-cylindrical or semi-cylindrical housing forms for the shell can be considered.
- the most favorable joining technique results from the quick handleability by the user with a stable sufficient strength of shell and connector - even in adverse climatic conditions, such as. big wind loads in connection with wetness.

Das deutsche Gebrauchsmuster
Die Herstellung der Griffhülle in ihrer ovalen Form, der eingeprägten Griffmuschel und dem ausgeformten Kragen ist relativ aufwendig und macht auch einen oval geformten Ziehgriff erforderlich; zu berücksichtigen sind darüber hinaus die bodenseitigen Lüftungsschlitze. Das Abstützungselement muß auf Grund der gewählten räumlichen Geometrien als Dreibein ausgeführt werden.The production of the handle cover in its oval shape, the embossed handle shell and the molded collar is relatively expensive and also makes an oval-shaped pull handle required; In addition, the bottom-side ventilation slits must be taken into account. The support element must be performed as a tripod due to the selected spatial geometries.
Das deutsche Gebrauchsmuster
Nachteilig gestalten sich minimale Reibungsverluste zwischen Stützelement und Innenwand der Griffhülle beim Aus- und Einschieben des mit dem unteren Ende des ersten Rohrabschnitts - nach dem Führungsrohr - des Hauptgestänges fest verbundenen Stützelements.Disadvantageous design minimal friction between the support element and the inner wall of the handle shell during extension and insertion of the fixed to the lower end of the first pipe section - after the guide tube - the main rod support member.
Eine weitere amerikanische Patentschrift
Das Aufspreizen von Schirmteilen, wie Schirmgestänge und -bespannung, verhindert ein schirmteileschonendes Verpacken derselben in den Hülsen. Da die Hülsen nur durch ihre Gleitreibung gesichert sind, bildet sich an der Überlappung beider Hülsen eine Knickstelle, die zum Verkanten der Rohrhülsen führen kann.The spreading of shielding parts, such as umbrella rods and stringing, prevents shielding-friendly packaging of the same in the sleeves. Since the sleeves are only secured by their sliding friction, forms at the overlap of both sleeves a kink, which can lead to tilting of the tube sleeves.
Das deutsche Patent
Die Teilezahl in der Umgebung des Handgriffs mit bodengelagerter Führungstange, verfahrbarem, rastbaren Kolben und zweiteiligem Doppelrohr-Handgriff ist in der Produktion aufwendig herstellbar.The number of parts in the vicinity of the handle with floor-mounted guide rod, movable, lockable piston and two-piece double-tube handle is expensive to produce in production.
Alle vorgestellten Veröffentlichungen eignen sich nur bedingt oder gar nicht für den spezifischen Einsatz als kompakter Schirm mit zusätzlicher weiterer Funktionalität wie eine Hülle - insbesondere nicht für einen faltbaren Taschenschirm mit einem hohlzylinderförmigen Körper als Schirmhülle und Griffhülle oder Traggriff.All publications presented are only partially or not at all for the specific use as a compact umbrella with additional additional functionality such as a shell - especially not for a foldable pocket umbrella with a hollow cylindrical body as a shield shell and handle cover or carrying handle.
Der Erfindung liegt daher die Aufgabe zu Grunde, eine Einrichtung nach dem Oberbegriff des Anspruchs 1, einen kompakten Schirm mit zusätzlicher weiterer Funktionalität wie eine Hülle - insbesondere einen faltbaren Taschenschirm mit einem hohlzylinderförmigen Körper als Schirmhülle und Griffhülle oder Traggriff - zu schaffen.The invention is therefore based on the object, a device according to the preamble of
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst; auf vorteilhafte Ausgestaltungen nehmen die Unteransprüche Bezug. Ziel ist der Aufbau eines kompakten Schirms mit zusätzlicher weiterer Funktionalität wie eine Hülle - insbesondere eines faltbaren Taschenschirms mit einem hohlzylinderförmigen Körper als Schirmhülle und Griffhülle oder Traggriff. Die vorgestellte Neuerung zeichnet sich im Gegensatz zu den vorgestellten Anmeldungen durch ihre Einfachheit aus. Die zylindrische Schirmhülle dient sowohl dem Transport des faltbaren Taschenschirms als auch als Traggriff für den Schirm in Arbeitsstellung. Im Gegensatz zu den oben genannten Veröffentlichungen sind beim Schirm in Arbeitsstellung die Schirmhülle und die/der Griffhülle/Tragegriff einschalig - und nicht zweischalig - ausgeführt.This object is achieved by the characterizing features of
In einer weiteren bevorzugten Ausführungsform der Erfindung verfügt der faltbare Taschenschirm über einen bekannten, handelsüblichen Dachaufbau bestehend aus einem teleskopierbaren Hauptgestänge, einem Schirmgestänge mit Bespannung und einer Dachkrone. An dem der Dachkrone entgegengesetzten Ende des Hauptgestänges besitzt der Schirm einen Verbinder, mit der Eigenschaft, daß er einerseits Träger eines hohlzylinderförmigen Körpers als Schirmhülle mit eingeschlossenem Schirmgestänge und Bespannung ist und andererseits - in einer um 180° gedrehten Stellung - den hohlzylinderförmigen Körper als Griffhülle/Traggriff bei offen liegendem Schirmgestänge und Bespannung - geschlossene oder geöffnete Schirmstellung - aufnehmen kann.In a further preferred embodiment of the invention, the foldable pocket umbrella has a known, commercially available roof structure consisting of a telescopic main linkage, an umbrella rod with stringing and a roof crown. At the end opposite the roof crown of the main boom of the screen has a connector, with the property that it is on the one hand support a hollow cylindrical body as a shield shell with enclosed umbrella linkage and clothing and on the other hand - in a rotated position by 180 ° - the hollow cylindrical body as a handle cover / Carrying handle with open umbrella rod and covering - closed or open umbrella position - can accommodate.
Gemäß einer weiteren Ausprägung der erfinderischen Neuheit ist die vorzugsweise hohlzylinderförmig ausgeformte Griffhülle/Traggriff so ausgebildet, daß sie den Schirm im wesentlichen bestehend aus Führungsrohr, Stützelement, Hauptgestänge, Haupt- und Hilfsschieber, Dachkrone, Dachgestänge und Bespannung durch Falten und Zusammenschieben vollständig aufnehmen kann. Über einen gut zugänglichen vorzugsweise ebenfalls kreisrund geformten Ziehgriff, der abschließend mit dem Teleskoprohr als Dachkrone einstückig verbunden ist, ist eine schnelle Handhabung durch den Benutzer gegeben.According to a further embodiment of the inventive novelty, the preferably hollow cylindrical molded handle cover / carrying handle is designed so that it can completely absorb the screen consisting essentially of guide tube, support element, main linkage, main and auxiliary slide, roof crown, roof linkage and covering by folding and pushing together. About a readily accessible preferably also circular shaped pull handle, which is finally integrally connected to the telescopic tube as the roof, a quick handling by the user is given.
Eine weitere Ausgestaltung sieht vor, daß nach einer Schirmbenutzung der hohlzylinderförmige Körper als Traggriff von dem Verbinder entfernt und als Schirmhülle über das gefaltete Schirmgestänge mit Bespannung in einer leichten Drehbewegung übergestülpt und wiederum an dem Verbinder befestigt wird. Mindestens der Boden des hohlzylinderförmigen Körpers ist mit Durchbrüchen für die Schirmbelüftung und den Druckausgleich versehen. Als Material für den hohlzylinderförmigen Körper wird Kunststoff als auch dünn gewalztes Metall - wie Aluminiumblech, ähnlich den bekannten Getränkedosen - vorgeschlagen. Der Verbinder nimmt das Hauptgestänge einstückig auf; dessen Material kann ebenfalls Kunststoff oder Metall sein. Entscheidend für die Materialauswahl ist die Festigkeit der Verbindung, in der Hauptsache im Falle der Arbeitsweise - der Benutzung - des Schirms, weniger im Falle des Transports. Im Falle der Benutzung eines aufgespannten Schirms muß der Verbinder neben dem Eigengewicht des Schirms - auch eines nassen Schirms - die Windlast als Druck auf den Schirm aufnehmen. Der Gestaltung der Verbindungsstelle von hohlzylinderförmigem Körper und Verbinder muß besondere Beachtung geschenkt werden.A further embodiment provides that after a screen use of the hollow cylindrical body removed as a carrying handle of the connector and slipped over as a screen cover over the folded umbrella rod with string in a slight rotational movement and in turn secured to the connector. At least the bottom of the hollow cylindrical body is provided with openings for the screen ventilation and pressure equalization. As a material for the hollow cylindrical body plastic and thin rolled metal - such as aluminum sheet, similar to the known beverage cans - proposed. The connector receives the main linkage in one piece; its material may also be plastic or metal. Decisive for the choice of materials is the strength of the connection, mainly in the case of operation - the use - of the screen, less in the case of transport. In case of using a clamped screen, the connector must be next to the weight of the screen - even a wet screen - record the wind load as pressure on the screen. The design of the joint of hollow cylindrical body and connector must be given special attention.
In einer weiteren Ausgestaltung kann für die Aufnahme des Hauptgestänges der Verbinder mit einem Durchbruch oder einer Sack- oder Durchgangsbohrung versehen werden und nach Einführung des Hauptgestänges wird dieses mittels Madenschraube oder Stift senkrecht zur axialen Bohrung in radialer Richtung verschraubt oder verstiftet. Je nach Materialeinsatz ist auch ein Umspritzen des Hauptgestänges bzw. des Führungsrohrs mit Kunststoff angebracht. Es ist vorgesehen, das Hauptgestänge in verdrehsicherem oder verdrehbarem Verbund mit dem Verbinder auszuführen. Bei dem verdrehsicheren Verbund ist das Profil des verwindungssteifen Hauptgestänges polygonal ausgeprägt - also im Querschnitt ein Mehreck. In der verdrehbaren Ausführung ist das Stützelement zwischen Hauptgestänge bzw. Führungsrohr als Drehlager ausgebildet.In a further embodiment, the connector can be provided with a breakthrough or a blind or through hole for receiving the main boom and after introduction of the main linkage this is bolted or pinned by means of grub screw or pin perpendicular to the axial bore in the radial direction. Depending on the use of material, an encapsulation of the main rod or of the guide tube with plastic is also attached. It is intended to make the main linkage in a non-rotatable or rotatable connection with the connector. In the torsion-proof composite, the profile of the torsionally rigid main linkage is polygonal - that is, a polygon in cross section. In the rotatable embodiment, the support element between the main rod or guide tube is designed as a pivot bearing.
Im folgenden wird der hohlzylinderförmige Körper oder Behälter zur Verwendung als Schirmhülle oder als Griffhülle/Traggriff auch als Dose bezeichnet, gemäß des Arbeitstitels 'Schirm in der Dose'. Wegen der besonderen Bedeutung einer wiederholten dauerhaften Haltbarkeit von Verbinder und hohlzylinderförmigem Körper als Griffhülle oder Traggriff werden verschiedene mechanische lösbare Verbindungen vorgeschlagen, die sich auch nach den verwendeten Werkstoffen ausrichten, wie z.B.
- 1. Konusklemmung mit Silikonring
- 2. Konusklemmung mit Nut und Noppen
- 3. Metalldose mit Konus und Noppen
- 4. Konusklemmung mit Schraubverbindung
- 5. Konusklemmung mit Nocken-Dreh- oder Twist-off-Schraubverschluß
- 6. Verbinder-Nocken-Dreh- oder Twist-off-Schraubverschluß
- 7. Dosen-Nocken-Dreh- oder Twist-off-Schraubverschluß
- 8. Einfache Schraubverbindung.
- 1. cone clamping with silicone ring
- 2. cone clamping with groove and nubs
- 3. Metal box with cone and nubs
- 4. cone clamping with screw connection
- 5. cone clamping with cam-twist or twist-off screw cap
- 6. Connector Cam Twist or Twist-Off Screw Cap
- 7. Canned cam twist or twist-off screw cap
- 8. Simple screw connection.
Bei der Konusklemmung wird die Dosenwandung im oberen axialen Bereich mit einem Einführkonus von ca. 0,5° auf der Innenseite wirkend versehen. Entsprechend erhält auch die Wandung des Verbinders in axialer Richtung einen solchen Konus derart gestaltet, daß die Verjüngung in der von der Schirmseite abgewandten axialen Richtung erfolgt und sich die Wirkung der festen Verbindung bei Einbringung des Verbinders in die Dose als Traggriff mit leichter Drehbewegung entfaltet. Am oberen seitlichen, dem Schirm zugewandten Rand des Verbinders ist ein zusätzlicher Silikonring eingelassen, der zusätzlich für eine Versteifung der Verbindung durch Reibschluß sorgt. Die Trennung der lösbaren Verbindung erfolgt durch leichtes Drehen der Dose bei gleichzeitigem Ziehen des Hauptgestänges bzw. Führungsrohrs.When cone clamping the can wall is provided in the upper axial region with an insertion cone of about 0.5 ° acting on the inside. Accordingly, the wall of the connector in the axial direction receives such a cone designed such that the taper takes place in the axial direction facing away from the screen side and unfolds the effect of the solid compound upon insertion of the connector into the can as a carrying handle with slight rotational movement. At the upper side, the screen facing edge of the connector, an additional silicone ring is embedded, which also provides a stiffening of the connection by frictional engagement. The separation of the detachable connection is made by slightly turning the can while pulling the main rod or guide tube.
Bei dieser Klemmverbindung erhalten Dosenwandung und Verbinderwandung je einen Einführkonus - wie unter Pkt. 1. Darüber hinaus arbeitet diese Klemmverbindung nach dem 'Nut-und-Feder-Prinzip'. Der Verbinder erhält an seinem oberen, dem Schirm zugewandten Außenrand eine rundliche Nut und die Dose als Griffhülle/ Traggriff an der oberen Innenwand ihrer offenen Seite über den Umfang räumlich versetzt angeordnete längliche Noppen, wobei nach dem Zusammenfügen von Dose und Verbinder die Noppen in den Nuten festsitzend geführt werden. Die Trennung von Dose und Verbinder erfolgt durch leichtes gegeneinander Verdrehen von Dose und Verbinder bei gleichzeitigem, trennendem Zug zwischen den beiden Teilen.In this clamped connection, the socket wall and the connector wall are each provided with an insertion cone - as described in
Handelt es sich bei der Dose als Griffhülle/Traggriff entsprechend der Klemmverbindung unter Pkt. 2 um eine Metalldose, können die an der oberen Innenwand ihrer offenen Seite über den Umfang räumlich versetzt angeordneten länglichen Noppen mittels eines zylindrischen Kunststoffrings gebildet werden, der paßgenau über die Dosen-Innenwand gestülpt wird und am oberen Ende über eine Wulst verfügt, die sich über den scharfen Rand der offenen Seite der Metalldose fügt, wobei dieser Kunststoffring seine Lage zwischen Dosen-Innenwand und Verbinder-Außenwand in Form einer Presspassung findet. Je nach Materialauswahl stellt der Kunststoffring einen guten Reibschluß zwischen der glatten Metalloberfläche und der Verbinder-Außenwand her.If the can is a handle / carrying handle according to the clamping connection under Pkt. 2 to a metal can, the spatially offset on the upper inner wall of its open side over the circumference arranged elongated knobs can be formed by a cylindrical plastic ring, the exact fit on the cans Inner wall is slipped and at the upper end has a bead that fits over the sharp edge of the open side of the metal can, this plastic ring finds its position between the can inner wall and connector outer wall in the form of a press fit. Depending on the choice of material, the plastic ring provides good frictional engagement between the smooth metal surface and the connector outer wall.
Bei dieser Klemmverbindung erhalten Hüllenwandung und Verbinderwandung je einen Einführkonus - wie unter Pkt. 1. Zusätzlich erhält die Dosen-Innenwand an ihrem oberen, offenen Ende ein nichtdurchgehendes Schraubgewinde mit mehreren Eingängen, ähnlich einem Bajonett-Verschluß. Der Verbinder erhält an seinem oberen, dem Schirm zugewandten Außenrand ebenfalls das nicht durchgehende Gewinde-Pendant. Der Verschluß erfolgt zunächst durch Fügen von Hülle und Verbinder an den gewindefreien Eingängen der Verschraubung, bei sich anschließendem gegeneinander Verdrehen bis zum festen Sitz von Hülle und Verbinder. Durch die entgegengesetzte Drehbewegung wird das Lösen und Trennen von Hülle und Verbinder vorbereitet. Der jeweilige Drehwinkel zum Festsetzen und Lösen ist jeweils kurz und beträgt nur eine Viertel- oder Drittel-Drehung vom Vollkreis. Gedreht wird gegen einen Anschlag - einen seitlichen Überstand auf der Außenwand - des Verbinders. Da die Dose als Schirmhülle und Traggriff um 180° verdreht Verwendung findet, ist oberhalb des Anschlags des Verbinders in axialer Richtung eine weitere gleichgeartete Gewindeanordnung angebracht.In this clamp connection shell wall and connector wall get each an insertion cone - as in
Eine weitere Lösung für den Verschluß von Dose als Griffhülle/Traggriff und Verbinder stellt der Nocken-Dreh- oder Twist-off-Schraubverschluß dar. Bei dieser Klemmverbindung erhalten Dosenwandung und Verbinderwandung je einen Einführkonus - wie unter Pkt. 1. Zusätzlich erhält die Dosen-Innenwand an ihrem oberen, offenen Ende mehrere versetzte Anlaufschrägen, die von entsprechend angeordneten Nocken auf der Außenwand des Verbinders nach dem Stecken durch Reibschluß festgesetzt werden. Die nach dem Schließen unter Federspannung stehenden Nocken bewirken einen besonders festen Verschluß der zu verbindenden Teile. Durch die entgegengesetzte Drehbewegung wird das Lösen und Trennen von Dose und Verbinder vorbereitet. Der jeweilige Drehwinkel zum Festsetzen und Lösen ist jeweils sehr kurz und beträgt nur ein Bruchteil des Vollkreises. Gedreht wird gegen einen Anschlag - einen seitlichen Überstand auf der Außenwand - des Verbinders. Da die Dose als Schirmhülle und Traggriff um 180° verdreht Verwendung findet, ist oberhalb des Anschlags des Verbinders in axialer Richtung eine weitere gleichgeartete Nockenanordnung angebracht.Another solution for the closure of the can as handle / handle and connector is the cam-twist or twist-off screw. With this clamp connection can wall and connector wall get each an insertion cone - as under
Eine weitere Ausführungsform des Verschlusses von Dose und Verbinder ist wie unter Pkt. 5 gegeben, mit dem Unterschied, daß durch den festen Sitz der Nocken-Dreh- oder Twist-off-Schraubverbindung auf die Konusschrägen unter Pkt. 1 verzichtet wird und dadurch der Verbinder in axialer Richtung flacher baut.Another embodiment of the closure of the box and connector is given as in item 5, with the difference that is dispensed by the tight fit of the cam-twist or twist-off screw on the cone bevels under
In einer weiteren Ausgestaltung des Dose-/Verbinder-Verschlusses wird die Umkehrung der Halteelemente von Nocken und Anlaufschrägen vorgeschlagen. Der Verschluß - ähnlich Pkt. 6 ein Nocken-Dreh- oder Twist-off-Schraubverschluß - ist dadurch gegeben, daß der obere, offene Dosenrand auf seiner Innenseite die über den Umfang angeordneten Nocken trägt und der Verbinder die umlaufenden Anlaufschrägen besitzt. Die Verriegelung erfolgt auch gegen einen Anschlag auf der Umfangswand des Verbinders; beiderseits des Anschlags sind die Anlaufschrägen spiegelbildlich angeordnet.In a further embodiment of the can / connector closure, the reversal of the holding elements of cams and chamfers is proposed. The closure - similar to section 6 a cam-twist or twist-off screw - is given by the fact that the upper, open edge of the can carries on its inside the circumferentially arranged cam and the connector has the peripheral run-on slopes. The lock is also against a stop on the peripheral wall of the connector; on both sides of the stop the run-up slopes are arranged in mirror image.
Gemäß einer weiteren Ausprägung des Dose-/Verbinder-Verschlusses wird die feste lösbare Verbindung durch beidseitige Schraubgewinde gebildet. Zu diesem Zweck erhält die obere, offene Dosen-Innenwand einige Gewindegänge und der mit einem Anschlag auf der Außenwand versehene Verbinder ebenfalls entsprechende Gewindegänge. Zur beidseitigen Verwendung der Dose als Schirmhülle und als Griffhülle/ Traggriff erhält der Verbinder ein an dem Anschlag in axialer Richtung gespiegeltes, weiteres äquivalentes Gewinde. Die Auslegung des Gewindes nach Anzahl und Winkel der Steigungen ist u.a. materialabhängig; der Drehwinkel zum Festsetzen oder Lösen der Verbindung ist jedenfalls ein Vielfaches größer als beim Nocken-Dreh- oder Twist-off-Schraubverschluß.According to another embodiment of the can / connector closure, the fixed detachable connection is formed by double-sided screw thread. For this purpose, the upper, open can inner wall receives a few threads and the connector provided with a stop on the outer wall also corresponding threads. For both-sided use of the can as a screen cover and as a handle cover / carrying handle, the connector receives a mirrored to the stop in the axial direction, another equivalent thread. The design of the thread according to the number and angle of the slopes is u.a. depending on the material; the angle of rotation for setting or loosening the connection is in any case many times greater than in the case of the cam-turning or twist-off screw-type closure.
Ein weiterer Vorteil in der Ausprägung des faltbaren Taschenschirms mit Dosengriff liegt in der ergonomischen und werbetechnischen Ausgestaltung der Schirmhülle; die vorzugsweise hohlzylindrische Bauform des Kunststoff- oder Metallkörpers liegt dem Benutzer gut in der Hand, vermittelt dem Träger durch die hochwertigen Materialien ein besonderes Gefühl für die Werthaltigkeit und bietet eine ideale Werbefläche auch bei nicht geöffneter Bespannung.Another advantage in the expression of the foldable pocket umbrella with can handle lies in the ergonomic and promotional design of the screen cover; the preferably hollow cylindrical design of the plastic or metal body is the user well in the hand, conveys the carrier through the high quality materials a special feeling for the value retention and offers an ideal advertising space even with unopened clothing.

Eine weitere Variante des Verbindungsaufbaus von Schirmhülle und Griffhülle/Traggriff 2 und Verbinder 4 des Taschenschirms 1 zeigt
Mit
Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß es für die Verpackung eines faltbaren Taschenschirms für den Transportzustand sowie die Nutzung des Schirms mittels einer/s Griffhülle/Traggriffs nur ein hohlzylinderförmiges Bauteil zum Einsatz kommt. Beispielhaft werden einige mögliche Aufbau- und Verbindungstechniken für die feste lösbare Verbindung von Hülle und Verbinder vorgeschlagen; weitere Verbindungen - wie ein Bajonett-Verschluß mit Klipsung oder Rastung - können ebenfalls in Erwägung gezogen werden. Je nach Gestaltung der festen, lösbaren Verbindung können auch weitere, nichtzylindrische oder teil- oder semizylindrische Gehäuseformen für die Hülle angedacht werden. Die günstigste Verbindungstechnik ergibt sich aus der schnellen Handhabbarkeit durch den Benutzer bei einer stabilen ausreichenden Festigkeit von Hülle und Verbinder - auch bei widrigen klimatischen Bedingungen, wie z.B. große Windlasten in Verbindung mit Nässe.The advantages that can be achieved with the invention are, in particular, that only a hollow-cylindrical component is used for the packaging of a foldable pocket umbrella for the transport state and the use of the umbrella by means of a handle cover / carrying handle. By way of example, some possible construction and connection techniques are proposed for the fixed detachable connection of casing and connector; other connections - such as a bayonet closure with Klipsung or detent - can also be considered. Depending on the design of the fixed, detachable connection, other, non-cylindrical or semi-cylindrical or semi-cylindrical housing forms for the shell can be considered. The most favorable joining technique results from the quick handleability by the user with a stable sufficient strength of shell and connector - even in adverse climatic conditions, such as. big wind loads in connection with wetness.
Vorteilhafte Weiterentwicklungen der Erfindung sind Gegenstand der Unteransprüche; die zahlreichen Möglichkeiten und Vorteile der Ausgestaltung der Erfindung spiegeln sich in der Anzahl der Schutzrechtsansprüche wider.Advantageous developments of the invention are the subject of the dependent claims; The numerous possibilities and advantages of the embodiment of the invention are reflected in the number of patent claims.
