Description

Die vorliegende Erfindung bezieht sich auf eine Schwimmscheibe mit Auftrieb in Wasser, welche Clipverbindungselemente umfasst, um mehrere Schwimmscheiben zu einer Schwimmhilfsvorrichtung zu verbinden und dabei eine sichere, aber gleichwohl einfach zu handhabende Verbindung zu gewährleisten.The present invention relates to a buoyancy float in water, which comprises clip connection elements to connect a plurality of floating discs to a swimming aid device, while ensuring a safe, but nevertheless easy to handle connection.

Neuartige Schwimmhilfsvorrichtungen erfreuen sich wachsender Beliebtheit. Während es in früherer Zeit üblich war, aufblasbare Schwimmhilfsvorrichtungen zu verwenden (z.B. DE 2134747 ), welche durch die Menge der eingeblasenen Luft flexibel an z. B. einen Oberarm einer Person anpassbar waren, gibt es mittlerweile Schwimmhilfsvorrichtungen, welche ohne das Einblasen von Luft verwendet werden können. Dies hat den Vorteil, dass Schwimmhilfsvorrichtungen keiner Gefahr von Leckage von z.B. Luft oder Weichmachern, insbesdondere bei Fehlanwendungen von Kleinkindern, und somit Sicherheitsbedenken ausgesetzt sind.
So beschreibt z.B. DE 29506606 U1 eine Schwimmhilfe mit konstant hoher Auftriebskraft mit einem Auftriebskörper pro Arm.Novel swimming aid devices are becoming increasingly popular. While it was customary in former times to use inflatable swimming aid devices (eg DE 2134747 ), which by the amount of injected air flexible at z. B. an upper arm of a person were customizable, there are now swimming aid devices that can be used without the injection of air. This has the advantage that swimming aid devices are not exposed to any risk of leakage of, for example, air or plasticizers, especially in case of misuse of infants, and thus safety concerns.
So describes eg DE 29506606 U1 a buoyancy aid with a constant high buoyancy with one buoyant body per arm.

Um solche Schwimmhilfsvorrichtungen, auch Oberarm-Schwimmhilfen mit konstant hoher Auftriebskraft genannt, flexibel an das Körpergewicht einer zu sichernden Person anzupassen, könnten mehrere, beispielsweise scheibenförmige Elemente der Schwimmhilfsvorrichtung, im Folgenden auch Schwimmscheiben genannt, miteinander einer Oberarm-Schwimmhilfe miteinander verbunden werden. So wären bei einer Person mit höherem Körpergewicht mehrere Elemente vorzusehen und zu verbinden als bei einer Person mit niedrigem Körpergewicht.To such a swimming aid devices, also called upper arm buoyancy aids with constant high buoyancy force to adapt flexibly to the body weight of a person to be secured, several, for example disc-shaped elements of the swimming aid device, hereinafter also called floating discs, could be connected together an upper arm buoyancy aid. Thus, a person with a higher body weight would have more elements to provide and connect than a person with a low body weight.

So beschreibt EP 0 046 205 A1 eine Schwimm- und Rettungshilfe in Ringform, welche mindestens eine flache Ringscheibe umfasst, welche Vorsprünge und Vertiefungen zum Zusammenstecken mit weiteren Ringschreiben aufweist.So describes EP 0 046 205 A1 a floating and rescue aid in ring form, which comprises at least one flat annular disc, which has projections and depressions for mating with other circular writing.

DE 20301304 U1 beschreibt ein Schwimmbrett mit Clipverbinder und Öffnungsschlüssel, wobei mehrere Schwimmbretter durch einen Clipverbinder nebeneinander liegend miteinander verbunden werden können. DE 20301304 U1 describes a swimming board with clip connector and opening key, with several swimming boards can be connected by a clip connector lying side by side.

Es ist daher Aufgabe der vorliegenden Erfindung, eine Verbindungsvorrichtung für zwei oder mehrere Schwimmscheiben zur Verfügung zu stellen, welche eine ausreichende Festigkeit vorweist, um zwei oder mehr Schwimmscheiben sicher zu verbinden, so dass eine kleine Kraft, welche auf eine oder mehrere Schwimmscheiben ausgeübt wird, nicht ausreicht, die Verbindung zu trennen.It is therefore an object of the present invention to provide a connecting device for two or more floating disks, which has sufficient strength to securely connect two or more floating disks, so that a small force exerted on one or more floating disks, insufficient to disconnect.

Diese Aufgabe wird durch eine Schwimmscheibe mit den Merkmalen gemäß Anspruch 1 sowie durch ein System aus Verbindungsvorrichtungsschirmscheiben gemäß Anspruch 9 gelöst. Weitere vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der abhängigen Ansprüche.This object is achieved by a floating disk with the features of claim 1 and by a system of Verbindungsschirmrichtschirmscheiben according to claim 9. Further advantageous embodiments of the invention are the subject of the dependent claims.

Wenn Schwimmscheiben nur aus porösem Weichmaterial gefertigt wären, bei denen Verbindungen ebenfalls aus porösem Weichschaum gefertigt und somit integral mit diesen Schwimmscheiben ausgebildet wären, wären jedoch Nachteile möglich. Denn wenn die Schwimmscheiben aus porösem Weichmaterial gefertigt wären und dieses leicht verform- bzw. deformierbar ist, träfe dies ebenfalls auf die Verbindungselemente zu, welche mit den Schwimmscheiben integral ausgebildet sind. Daher könnten sich die Verbindungen bereits bei der Ausübung von geringen Kräften lösen. Abgesehen von Sicherheitseffekten würde ein Lösen solcher Verbindungen auch zu einer schlechteren Handhabbarkeit führen.If floating disks were made only of porous soft material, in which compounds were also made of porous flexible foam and thus formed integrally with these floating discs, but disadvantages would be possible. For if the floating disks were made of porous soft material and this is easily deformed or deformed, this would also apply to the connecting elements, which are integrally formed with the floating disks. Therefore, the compounds could already dissolve in the exercise of small forces. Apart from safety effects, a release of such compounds would also lead to a poorer handling.

Die vorliegende Erfindung beinhaltet demgegenüber eine Schwimmscheibe mit Auftrieb im Wasser, welche mindestens eine Aussparung besitzt, in die ein Clipverbindungselement fest oder entnehmbar eingesetzt ist. Das Clipverbindungselement dient zur Verbindung mehrerer Schwimmscheiben. Das Clipverbindungselement weist einen Grundkörper auf, welcher vorzugsweise hohl ausgebildet ist und mit einem Vorsprung mit einer Nut versehen ist, um eine Verbindung vom Typ Nut- und Federverbindung zu realisieren.The present invention, in contrast, includes a floating disk with buoyancy in the water, which has at least one recess into which a clip connecting element is inserted firmly or removably. The clip connection element is used to connect several floating discs. The clip connecting element has a base body, which is preferably hollow and is provided with a projection with a groove in order to realize a connection of the tongue and groove type.

Mit dem Clipverbindungselement können mehrere Schwimmscheiben miteinander verbunden werden. Pro Schwimmscheibe ist mindestens ein Clipverbindungselement vorzusehen.With the clip connection element several floating disks can be connected to each other. At least one clip connection element must be provided per floating disk.

Durch die Verwendung dieses Clipverbindungselements sind mehrere Schwimmscheiben so verbindbar, dass sie sich bei der Benutzung im Wasser nicht lösen. Weiterhin sind je nach Bedarf der Person, welche die Schwimmhilfsvorrichtung benutzt, mehrere Schwimmscheiben aneinander befestigbar, je nach Gewicht der Person.By using this clip connector several floating disks are connectable so that they do not dissolve when used in the water. Furthermore, depending on the needs of the person who uses the Schwimmhilfsvorrichtung, several floating discs can be fastened together, depending on the weight of the person.

Eine Schwimmscheibe mit Auftrieb im Wasser besitzt vorzugsweise zwei Aussparungen nahe relativ den sich gegenüberliegenden Außenkanten, in die Clipverbindungselemente fest oder entnehmbar eingesetzt sind. Durch diese vorzugsweise Anordnung wird eine optimale Spannungsverteilung erzielt, und ein ungewolltes Lösen der Verbindung wird unwahrscheinlicher. Die Clipverbindungselement zur Verbindung mehrerer Schwimmscheiben weisen auf: Einen Grundkörper mit einer Aussparung, einen Fortsatz, welcher an einer Stirnseite des Grundkörpers vorgesehen ist und einen Vorsprung an der äußeren Fläche aufweist, eine Nut in der Aussparung, welche auf einem der Stirnseite gegenüberliegenden äußeren Abschnitt der Innenseite des Grundkörpers vorgesehen ist, in welcher ein Vorsprung des Fortsatzes eines weiteren Clipverbindungselements aufnehmbar ist, wobei ein Clipverbindungselement mit dem Vorsprung sowie der Nut jeweils eine Clipverbindung mit einem weiteren Clipverbindungselement ausbilden kann. Vorzugsweise ist der Grundkörper aus Kostengründen im Wesentlichen innen hohl. Ferner spart eine solche Ausgestaltung Gewicht.A floating disk with buoyancy in the water preferably has two recesses near relative to the opposite outer edges, are inserted into the clip fasteners fixed or removable. By this preferred arrangement, an optimal stress distribution is achieved, and an unwanted release of the connection is less likely. The clip connection elements for connecting a plurality of floating discs have a base body with a recess, a projection which is provided on an end side of the base body and has a projection on the outer surface, a groove in the recess, which on one of the front side opposite outer portion of Inside the base body is provided, in which a projection of the extension of another clip connection element is receivable, wherein a clip connection element with the projection and the groove can each form a clip connection with another clip connection element. For reasons of cost, the main body is preferably substantially hollow on the inside. Furthermore, such a design saves weight.

Eine Schwimmscheibe basiert vorzugsweise auf einem porösen oder geschäumten Kunststoff, welcher hinreichenden Auftrieb im Wasser ermöglicht, bevorzugt wasserabweisend ist und somit kein Wasser absorbieren kann und eine möglichst geringe Dichte besitzt.A floating disk is preferably based on a porous or foamed plastic, which allows sufficient buoyancy in the water, preferably water-repellent and thus can not absorb water and has the lowest possible density.

An der äußeren Umfangsoberfläche des Grundkörpers des Clipverbindungselements ist weiterhin mindestens ein Vorsprung zur Fixierung des Clipverbindungselements in einer Schwimmscheibe vorgesehen, vorzugsweise sind sogar zwei Vorsprünge vorgesehen, wobei einer auf der Vorderseite der Schwimmscheibe aufliegt, der andere auf der Rückseite. Somit kann eine optimale Fixierung des Clipverbindungselements in der Aussparung der Schwimmscheibe erreicht werden.At least one projection for fixing the clip connection element in a floating disk is provided on the outer peripheral surface of the base body of the clip connection element, preferably even two projections are provided, one rests on the front of the floating disk, the other on the back. Thus, an optimal fixation of the clip connection element in the recess of the floating disk can be achieved.

Beim Clipverbindungselement ist die Nut vorzugsweise auf dem gesamten Umfang der Innenseite des Grundkörpers vorgesehen. Dies führt zur stabilsten Verbindung, weiterhin besitzt eine solche Ausführungsform die geringste Bruchneigung, da sich eventuelle Zugkräfte am besten auf das Material verteilen. Aus demselben Grund ist der der Vorsprung auf dem Fortsatz vorzugsweise auf dem gesamten Umfang des Vorsprungs vorgesehen.In the clip connection element, the groove is preferably provided on the entire circumference of the inside of the base body. This leads to the most stable connection, furthermore, such an embodiment has the lowest tendency to break, since any tensile forces are best distributed over the material. For the same reason, the protrusion on the protrusion is preferably provided on the entire circumference of the protrusion.

Ein Clipverbindungselement ist bevorzugt aus Hartplastik ausgebildet. Dieses bietet bei hinreichender Auftriebskraft in Wasser eine ausreichende Festigkeit und Stabilität, so dass eine Verbindung zwischen zwei Schwimmscheiben bis zu einer gewissen Zugkraft stabil sind und sich durch Kräfte, welches Wasser bei beschreibungsgemäßer Verwendung auf die Schwimmscheiben ausüben kann, nicht löst.A clip connection element is preferably made of hard plastic. This provides sufficient buoyancy in water sufficient strength and stability, so that a connection between two floating disks are stable to a certain tensile force and not by forces, which can exercise water when used as inscribed on the floating disks.

Eine Schwimmhilfsvorrichtung umfasst mindestens zwei Schwimmscheiben gemäß einem vorhergehenden Punkte, welche durch besagte Clipverbindungselemente verbunden sind.A swimming aid device comprises at least two floating discs according to a previous point, which are connected by said clip connection elements.

Im Folgenden wird beispielhaft ein bevorzugtes Ausführungsbeispiel unter Bezugnahme auf die beigefügten Zeichnungen näher erläutert, ohne die Erfindung jedoch darauf zu beschränken.

In the following, a preferred embodiment is explained by way of example with reference to the accompanying drawings, but without limiting the invention thereto.
Fig. 1
Figure 11 is an isometric view of the clip connector for use in a floating disc.
Fig. 2
is an isometric view of a floating disk, including the notches for clip fasteners.
Figure 3
is an exploded view showing a combination of three clip fasteners 1, 1 'and 1 ".

Fig. 1 zeigt das durchgängige Clipverbindungselement 1, welches einen Grundkörper 2 mit einer Vertiefung 12 besitzt. Im vorliegenden Fall ist die Vertiefung so tief, dass der Grundkörper 2 innen hohl ausgeführt ist. An einer Stirnseite des Grundkörpers 2 ist ein Fortsatz 3 vorgesehen, welcher wiederum einen Vorsprung 4 an der äußeren Fläche aufweist. Dieser Vorsprung 4 in der äußeren Fläche dient zu einer Clipverbindung mit einem weiteren Clipverbindungselement 1. An der Innenseite der Vertiefung 12 des Grundkörpers 2 ist weiterhin eine Nut 5 (in Fig. 1, als dicke Linie dargestellt) vorgesehen, die so angepasst ist, dass sie wiederum einen Vorsprung 4' eines Fortsatzes 3' eines weiteren Clipverbindungselements 1' aufnehmen kann, und somit eine Nut-/Federverbindung einzugehen. Weiterhin besitzt das Clipverbindungselement 1 auf der äußeren Umfangsfläche zwei Vorsprünge 6 und 7, welche dazu angepasst sind, das Clipverbindungselement 1 in einer Schwimmscheibe fixieren, in dem sie auf den Oberflächen der Schwimmschreibe aufliegen können und somit ein Herausrutschen der Clipverbindungselemente aus der Schwimmscheibe verhindern. Fig. 1 shows the continuous clip connection element 1, which has a base body 2 with a recess 12. In the present case, the depression is so deep that the base body 2 is made hollow inside. On an end face of the main body 2, an extension 3 is provided, which in turn has a projection 4 on the outer surface. This projection 4 in the outer surface is used for a clip connection with another clip connection element 1. On the inside of the recess 12 of the base body 2 is further a groove 5 (in Fig. 1 , shown as a thick line), which is adapted so that it in turn can receive a projection 4 'of an extension 3' of another clip connection element 1 ', and thus enter into a tongue and groove connection. Furthermore, the clip connection element 1 has on the outer circumferential surface two projections 6 and 7, which are adapted to fix the clip connection element 1 in a floating disk, in which they can rest on the surfaces of the floating letter and thus prevent slipping out of the clip connection elements from the floating disk.

Fig. 2 zeigt eine Ansicht einer Schwimmscheibe 8. Im vorliegenden Beispiel weist die Schwimmscheibe 8 zwei Aussparungen 9 auf, in die jeweils ein Clipverbindungselement 1 eingesteckt werden kann. Die beiden Vorsprünge 6 und 7 des Grundkörpers 2 des Clipverbindungselements 1 liegen hierbei mit beiden äußeren Oberflächen der Schwimmscheibe 8 auf. Weiterhin weist die Schwimmscheibe 8 eine Öffnung 10 auf, mit welcher die Schwimmscheibe 8 am Oberarm der zu haltenden Person befestigt werden kann. In der inneren Umfangsoberfläche der Öffnung 10 in der Schwimmscheibe 8 ist ein Ring von flexiblem, elastischem Material 11 angebracht, welche weiterhin zum reversiblen Fixieren der Schwimmscheibe an den Oberarm der zu haltenden Person beiträgt. Fig. 2 shows a view of a floating disk 8. In the present example, the floating disk 8 has two recesses 9, in each of which a clip connection element 1 can be inserted. The two projections 6 and 7 of the base body 2 of the clip connection element 1 in this case lie with both outer surfaces of the floating disk 8. Furthermore, the floating disk 8 an opening 10, with which the floating disk 8 can be attached to the upper arm of the person to be held. In the inner circumferential surface of the opening 10 in the floating disk 8, a ring of flexible, elastic material 11 is attached, which further contributes to the reversible fixing of the floating disk to the upper arm of the person to be held.

Fig. 3 ist eine Explosionszeichnung, welche eine Kombination aus 3 Clipverbindungselementen 1, 1' und 1" zeigt, wobei die Clipverbindungselemente 1 und 1' miteinander verbunden sind. Es wird deutlich, dass die Clipverbindungselemente 1 und 1" miteinander verbindbar sind, indem der Vorsprung 4 des Fortsatzes 3 des Clipverbindungselements 1 in die Vertiefung 12' des Clipverbindungselements 1" geschoben wird. Eine stabile Verbindung wird dann erzielt, wenn der Vorsprung 4 des Fortsatzes 3 des Clipverbindungselements 1 so weit in die Vertiefung 12" des Clipverbindungselements 1" hineingeschoben wird, so dass er in die Nut 5" (in Fig. 3 als dicke Linie dargestellt) einrastet. Fig. 3 is an exploded view showing a combination of 3 clip fasteners 1, 1 'and 1 "with the clip fasteners 1 and 1' joined together It will be understood that the clip fasteners 1 and 1" are connectable by having the protrusion 4 of FIG A stable connection is achieved when the projection 4 of the extension 3 of the clip connection element 1 is pushed so far into the recess 12 "of the clip connection element 1", so that he into the groove 5 "(in Fig. 3 shown as a thick line) engages.

Die vorliegende Erfindung ist nicht auf die oben genannten Ausführungsformen beschränkt.The present invention is not limited to the above embodiments.

Beispielsweise wäre es möglich, das Clipverbindungselement 1 ohne die beiden Vorsprünge 6 und 7 auszuführen, und das Clipverbindungselement 1 beispielsweise durch Zacken oder Stifte, welche auf der Außenfläche des Grundkörpers 2 vorgesehen sind, in weitere Aussparungen innerhalb des porösen Materials der Schwimmscheibe 8 zu fixieren. Auch wäre eine Nabenverbindung möglich. Eine Ausführung mit den beiden Vorsprüngen 6 und 7 führt jedoch zu einer festeren und sicheren Verbindung. Weiterhin ist eine Ausführungsform, bei der das Clipverbindungselement 1 nicht aus der Schwimmscheibe 8 entnehmbar ist, möglich, beispielsweise durch Verkleben beider Teile.For example, it would be possible to carry out the clip connection element 1 without the two projections 6 and 7, and the clip connection element 1, for example, by serrations or pins which are provided on the outer surface of the base body 2, in to fix further recesses within the porous material of the floating disk 8. Also, a hub connection would be possible. An embodiment with the two projections 6 and 7, however, leads to a firmer and secure connection. Furthermore, an embodiment in which the clip connection element 1 can not be removed from the floating disk 8 is possible, for example by gluing both parts together.

Weiterhin wäre es möglich, beim Clipverbindungselement 1 die Nut 5 und den Vorsprung 4 nicht auf dem gesamten Umfang der Innenseite des Grundkörpers auszuführen. In diesem Fall könnte trotzdem eine ausreichende Festigkeit der Clipverbindung zur Verfügung gestellt werden. Eine Ausführung Auf dem gesamten Umfang führt jedoch zu einer stabileren Verbindung von zwei Clipverbindungselementen.Furthermore, it would be possible for the clip connection element 1, the groove 5 and the projection 4 is not carried out on the entire circumference of the inside of the body. In this case, nevertheless sufficient strength of the clip connection could be provided. One embodiment However, the entire circumference results in a more stable connection of two clip connectors.

Weiterhin ist die Form des Grundkörpers 2 des Clipverbindungselements 1 nicht auf eine nierenförmige Form beschränkt. Es sind rechteckige, vieleckige, runde, ovale oder dreieckige Formen denkbar. Ein Vorteil der Nierenform ist jedoch, dass sich diese optisch gut an die äußere Umfangsrundung der Schwimmscheibe anpasst. Weiterhin ist ein Clipverbindungselement in Nierenform torsionssteifer und bietet eine stabilere Verbindung, gleichzeitig ist ein besserer Krafteingriff vorhanden.Furthermore, the shape of the base body 2 of the clip connection element 1 is not limited to a kidney-shaped form. There are rectangular, polygonal, round, oval or triangular shapes conceivable. An advantage of the kidney shape, however, is that it adapts optically well to the outer circumferential flattening of the floating disc. Furthermore, a kidney-shaped clip connector is more torsionally rigid and provides a more stable connection, while providing better force engagement.

Weiterhin wäre es möglich, das Clipverbindungselement 1 aus Metall auszuführen, beispielsweise aus einem leichten Metall wie Aluminium oder einer Aluminiumlegierung. Dieses Metall sollte ebenfalls hinreichend Auftrieb im Waser besitzen und nicht zu Rostbildung neigen. Plastik ist aber die kostengünstigere und auf jeden Fall korrosionsunanfälligere Variante.Furthermore, it would be possible to make the clip connection element 1 of metal, for example of a light metal such as aluminum or an aluminum alloy. This metal should also have sufficient buoyancy in the water and not tend to rust. But plastic is the cheaper and definitely more corrosion-resistant variant.

Eine weitere Variante wäre die Ausführung der Schwimmscheibe 8 aus einem von porösem oder geschäumten Kunststoff verschiedenen Material mit Auftrieb in Wasser, wie zum Beispiel Kork oder kompositverstärkte Karbonfasern.Another variant would be the design of the floating disk 8 made of a different material of porous or foamed plastic with buoyancy in water, such as cork or composite-reinforced carbon fibers.

Weiterhin ist es möglich, zur Fixierung von mehreren Schwimmscheiben 8 aneinander eine Vielzahl an Clipverbindungselementen 1 vorzusehen. Hierzu muss eine Vielzahl von Aussparungen 9 in den Schwimmscheiben 8 vorgesehen werden. Eine räumliche Anordnung von zwei Clipverbindungselementen relativ nahe von zwei sich gegenüberliegender Außenkanten der Schwimmscheibe ist jedoch mit Hinblick auf ein Kraftfeld, welches auf die Schwimmscheiben einwirkt, stabiler, da eine solche Anordnung lediglich ein kleines Biegemoment zulässt. Ein größeres Biegemoment könnte leicht zum unbeabsichtigten Lösen der Verbindung führen.Furthermore, it is possible to provide a plurality of clip connection elements 1 for fixing a plurality of floating discs 8 together. For this purpose, a plurality of recesses 9 must be provided in the floating disks 8. However, a spatial arrangement of two clip connection elements relatively close to two opposite outer edges of the floating disk is more stable with respect to a force field which acts on the floating disks, since such an arrangement allows only a small bending moment. A larger bending moment could easily lead to inadvertent release of the connection.

Ein Clipverbindungselement 1, welches nur eine Clipverbindung mit einem anderen Clipverbindungselement 1 eingehen kann, kann als Front- bzw. Endstück einer Schwimmhilfsvorrichtung fungieren. Hierbei kann einerseits der Fortsatz (3) an einer Stirnseite des Grundkörpers (2) mit dem Vorsprung (4) an der äußeren Fläche weggelassen werden. Andererseits kann die Nut (5) weggelassen werden. In diesem Fall könnte der Grundkörper (2) an einer Seite verschlossen sein und somit nicht zu einer Seite hin geöffnet sein. Er könnte somit auch massiv ausgeführt sein und innen nicht hohl sein.A clip connection element 1, which can enter only one clip connection with another clip connection element 1, can act as a front or end piece of a swimming aid device. Here, on the one hand, the extension (3) on an end face of the main body (2) with the projection (4) on the outer surface can be omitted. On the other hand, the groove (5) can be omitted. In this case, the base body (2) could be closed on one side and thus not be open to one side. He could thus be executed solid and not hollow inside.

Weitere Ausführungsformen sind im Rahmen der vorliegenden Erfindung ebenfalls denkbar.Further embodiments are also conceivable within the scope of the present invention.
