Description

Schwimmhilfe Buoyancy aid
Beschreibungdescription
Die Erfindung betrifft eine Schwimmhilfe mit einem aufblasbaren Kissen aus faltbarem Material.The invention relates to a swimming aid with an inflatable cushion made of foldable material.
Beim Schwimmen in Küstennahe oder in einem See werden derartige Schwimmhilfen häufig verwendet, wenn der Schwimmer länger im Wasser bleiben und Überanstrengungen vermeiden möchte. Die Schwimmhilfen dienen auch zur Unterstützung für Kinder oder Nichtschwimmer. Als Kissen wird in den meisten Fällen eine Luft¬ matratze verwendet, die zuvor an Land aufgeblasen werden muß, um sie anschließend von Anbeginn an mit ins Wasser zu nehmen.When swimming near the coast or in a lake, such swimming aids are often used when the swimmer wants to stay in the water longer and avoid overexertion. The swimming aids are also used to support children or non-swimmers. In most cases an air mattress is used as a pillow, which must first be inflated on land in order to subsequently take it into the water from the beginning.
Der Erfindung liegt die Aufgabe zugrunde, eine Schwimmhilfe zur Verfügung zu stellen, die vom Schwimmer leicht getragen werden kann und erst dann ihre Auftriebsfunktion übernimmt, wenn der Schwimmer dies wünscht.The invention has for its object to provide a buoyancy aid that can be easily carried by the swimmer and only takes on its buoyancy function when the swimmer so wishes.
Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, daß das Kissen mit einer Tasche verbunden ist, die das nicht aufge¬ blasene Kissen in zusammengelegten Zustand einschließt und die einen Gürtel zum Befestigen am Körper des Schwimmers hat. Dabei ist es vorteilhaft, wenn das Kissen über ein Ventil mittels Druckgas aufblasbar ist.According to the invention, this object is achieved in that the pillow is connected to a pocket which encloses the non-inflated pillow in the folded state and which has a belt for fastening to the body of the swimmer. It is advantageous if the cushion can be inflated by means of compressed gas using a valve.
Mit der Erfindung steht eine Schwimmhilfe zur Verfügung, deren Tasche das zusammengefaltete Kissen vollständig aufnimmt und dabei einen sehr kleinen Platz einnimmt, so daß sie bequem am Körper getragen werden kann. Der Schwimmer hat damit die Möglichkeit, sich zunächst ohne den Einsatz der Schwiπunhilfe im Wasser aufzuhalten und zu schwimmen, ohne daß ihn ein aufgeblasenes Kissen stört. Erst dann, wenn der Schwimmer dies entscheidet, überführt er das Kissen in den aufgeblasenen Zustand, so daß dessen Auftriebskraft den Aufenthalt im Wasser erleichtert.With the invention, a swimming aid is available, the pocket of which completely takes up the folded cushion and thereby occupies a very small space, so that it can be worn comfortably on the body. The swimmer thus has the opportunity to stay and swim in the water without the use of the swimming aid, without being disturbed by an inflated cushion. Only when the swimmer decides to do so does he bring the pillow into the inflated state so that its buoyancy makes it easier to stay in the water.
Nach einem weiteren Merkmal der Erfindung ist das Ventil in der Tasche angeordnet; an das Ventil kann eine Druckgaspatrone an¬ geschlossen werden, die über einen Betätigungshebel geöffnet wird, so daß das ausströmende Druckgas das Kissen in Sekunden¬ schnelle aufbläst. Sowohl ein solches Ventil als auch kleine Druckgaspatronen sind im Handel erhältlich, so daß einerseits die Herstellung der Schwimmhilfe sehr kostengünstig ist und andererseits deren Anwendung keine Probleme bereitet, da die Druckgaspatronen bei Bedarf jederzeit nachgekauft werden können.According to a further feature of the invention, the valve is arranged in the pocket; A compressed gas cartridge can be connected to the valve, which is opened via an actuating lever, so that the outflowing compressed gas inflates the cushion quickly. Both such a valve and small compressed gas cartridges are commercially available, so that on the one hand the manufacture of the buoyancy aid is very inexpensive and on the other hand its use does not cause any problems, since the compressed gas cartridges can be bought at any time if necessary.
Nach einem weiteren Merkmal der Erfindung ist mit dem Kissen ein Anschlußrohr fest verbunden, auf das das Ventil aufgesetzt werden kann.According to a further feature of the invention, a connecting tube is firmly connected to the cushion, on which the valve can be placed.
Es ist günstig, wenn die Druckgaspatrone Kohlendioxid enthält. Derartige Druckgaspatronen haben einen äußerst geringen Bauraum und sind zu niedrigen Preisen verfügbar, beispielsweise zum Aufblasen von Fahrradreifen.It is advantageous if the compressed gas cartridge contains carbon dioxide. Such compressed gas cartridges have an extremely small space and are available at low prices, for example for inflating bicycle tires.
Eine besonders einfache und rasche Handhabung ist dann möglich, wenn die Tasche aufeinander faltbare Seitenwände mit Klettver- Schlußelementen hat. Damit läßt sich die Tasche im Wasser mühelos und innerhalb kürzester Zeit öffnen.A particularly simple and quick handling is possible if the bag can be folded side walls with Velcro Has final elements. This allows the bag to be opened easily and quickly in the water.
Die Tasche kann aus einem Kunststoffgewebe hergestellt werden. Das Kissen besteht vorzugsweise aus einem Synthetikgewebe, das mit Polyurethan beschichtet ist. Ein derartiges Material ist sehr luftdicht, so daß das Kissen im aufgeblasenen Zustand viele Stunden lang seine Form beibehält.The bag can be made from a plastic fabric. The pillow is preferably made of a synthetic fabric coated with polyurethane. Such a material is very airtight, so that the pillow maintains its shape for many hours when inflated.
Nach einem weiteren Merkmal der Erfindung ist es möglich, daß das Kissen auf seiner freien, nicht mit der Tasche verbundenen Seite ein Band hat, das um den Nacken des Schwimmers gelegt werden kann, um eine zusätzliche Lagesicherung herbeizuführen.According to a further feature of the invention, it is possible for the pillow to have a band on its free side which is not connected to the pocket and which can be placed around the neck of the swimmer in order to bring about additional securing of the position.
Die Erfindung ist nachstehend an einem Ausführungsbeispiel er¬ läutert, das in der Zeichnung dargestellt ist. Es zeigen:The invention is explained below using an exemplary embodiment which is illustrated in the drawing. Show it:

Figur 6 einen Schnitt in der Ebene VI - VI der Figur 5.6 shows a section in the plane VI - VI of FIG. 5.
Die Figuren 2 und 4 zeigen, daß die Schwimmhilfe als Auftriebs¬ körper ein aufblasbares Kissen 10 aus faltbarem Material hat, beispielsweise ähnlich einer Luftmatratze; das aufgeblasene Kissen 10 kann auch andere Formen haben, beispielsweiεe nach Art eines Quaders. Als Material für das Kissen 10 dient bevorzugt ein mit Polyurethan beschichtetes Synthetikgewebe. Gemäß Figur 2 ist der mittlere Teil 12 des Kissens 10 fest an der Rückwand 14 einer Tasche 16 angebracht; die beiden Seitenteile 18 können zum Zusammenfalten des Kissens 10 um die beiden Längsrippen 20 gelegt werden, welche die Seitenteile 18 mit dem mittleren Teil 12 verbinden. Anschließend wird das nicht aufgeblasene, leere Kissen 10 zusammengerollt oder rechtwinklig zu den Längsrippen 20 gefaltet, bis es die Form eines kleinen, etwa quaderformigen Päckchens hat, das vollständig in der Tasche 16 untergebracht werden kann.Figures 2 and 4 show that the buoyancy aid as a buoyancy body has an inflatable cushion 10 made of foldable material, for example similar to an air mattress; the inflated cushion 10 can also have other shapes, for example in the manner of a cuboid. A synthetic fabric coated with polyurethane is preferably used as the material for the pillow 10. According to Figure 2, the central part 12 of the pillow 10 is fixedly attached to the rear wall 14 of a pocket 16; the two side parts 18 can be used to fold the cushion 10 together about the two longitudinal ribs 20 be placed, which connect the side parts 18 to the central part 12. Subsequently, the uninflated, empty pillow 10 is rolled up or folded at right angles to the longitudinal ribs 20 until it has the shape of a small, approximately cuboid-shaped packet that can be completely accommodated in the pocket 16.
Die Tasche 16 besteht aus einem ebenfalls faltbaren Synthetik¬ gewebe und hat, wie Figur 2 zeigt, zwei Seitenlaschen 22, die über das zusammengefaltete, päckchenförmige Kissen 10 gelegt werden können. Mit Hilfe von Klettverschlußelementen 24 lassen sich die aufeinandergelegten Seitenlaschen 22 mühelos aneinander befestigen.The pocket 16 consists of a likewise foldable synthetic fabric and, as FIG. 2 shows, has two side flaps 22 which can be placed over the folded, packet-shaped cushion 10. With the help of Velcro fasteners 24, the superimposed side straps 22 can be easily attached to one another.
In ähnlicher Weise haben auch die beiden mit der Rückwand 14 verbundenen Frontlaschen 26 der Tasche 16 - in Figur 2 ist die zweite Frontlasche durch daε aufgeblasene Kissen 10 verdeckt - Klettverschlußelemente 24, die ein rasches Schließen und auch Öffnen der Tasche 16 gestatten.Similarly, the two front flaps 26 of the pocket 16 connected to the rear wall 14 - in FIG. 2, the second front flap is covered by inflated cushions 10 - Velcro fastener elements 24, which allow the pocket 16 to be closed and opened quickly.
Die Tasche 16 ist mit einem Gürtel 28 verbunden, der einen üblichen Schnellverschluß 30 sowie nicht weiter gezeigte Mittel zur Längenverstellung hat. Mit Hilfe des Gürtels 28 kann die Tasche 16 rasch und mühelos an der Taille 32 des Schwimmers be¬ festigt werden (vgl. Figur 3).The pocket 16 is connected to a belt 28, which has a conventional quick-release fastener 30 and means for length adjustment, not shown further. With the aid of the belt 28, the pocket 16 can be quickly and easily attached to the waist 32 of the swimmer (cf. FIG. 3).
Figur 2 zeigt, daß der durch das Innere der Tasche 16 gesteckte Teil des Gürtels 28 das untere Ende 34 des mittleren Teils 12 des Kissens 10 trägt. Auf dieses untere Ende 34 des Kissens 10 ist ein Ventil 36 aufgesetzt, dessen Mechanismus in den Figuren 5 und 6 näher dargestellt ist.FIG. 2 shows that the part of the belt 28 inserted through the inside of the pocket 16 carries the lower end 34 of the middle part 12 of the cushion 10. A valve 36, the mechanism of which is shown in more detail in FIGS. 5 and 6, is placed on this lower end 34 of the cushion 10.
Das Ventil 36 besteht aus einem Kunststoffgehäuse 38, das an einer Stirnseite einen Gewindeanschluß 40 für eine Druckgas- patrone 42 hat. In den Figuren 5 und 6 ist die Patrone 42 ver¬ kürzt dargestellt. Das Gehäuse 38 des Ventils hat eine von oben nach unten durchgehende Bohrung mit einer abgeflachten Seite 44, so daß es auf ein entsprechend geformtes Anschlußrohr 46 definiert aufgesetzt werden kann, das - wie Figur 6 schematisch zeigt - fest mit einer Wand 48 des Kissens 10 verbunden ist und in dieses mündet.The valve 36 consists of a plastic housing 38 which has a threaded connection 40 for a compressed gas cartridge 42 on one end face. 5 and 6, the cartridge 42 is shown shortened. The housing 38 of the valve has one from above downward through bore with a flattened side 44, so that it can be placed in a defined manner on a correspondingly shaped connecting tube 46 which - as shown schematically in FIG. 6 - is firmly connected to a wall 48 of the cushion 10 and opens into it.
An der der Patrone 42 gegenüberliegenden Stirnseite trägt das Gehäuse 38 einen Betätigungshebel 50, der um einen Stift 52 schwenkbar im Gehäuse 38 gelagert ist. Figur 5 zeigt den Betätigunshebel 50, dessen Form der Kontur des Gehäuses 38 angepaßt ist. Im Ruhezustand ist der Betätigungshebel 50 in einer Aussparung 76 des Gehäuses 38 versenkt.On the end face opposite the cartridge 42, the housing 38 carries an actuating lever 50 which is pivotably mounted in the housing 38 about a pin 52. Figure 5 shows the actuating lever 50, the shape of which is adapted to the contour of the housing 38. In the idle state, the actuating lever 50 is sunk in a recess 76 in the housing 38.
In dem Gehäuse 38 ist in Längsrichtung verschiebbar eine Nadel 54 gelagert, die von dem Betätigungshebel 50 gegen die Kraft einer Druckfeder 56 in Richtung auf die Patrone 52 ver¬ schoben werden kann, so daß die Spitze der Nadel 54 das von einer Metallkappe 58 verschlossene Ende der Patrone 42 öffnet. Zu diesem Zweck wird der Hebel 50 in die in Figur 5 gestrichelt eingezeichnete Stellung geschwenkt, wobei dessen kurzes Ende 60 die Nadel 54 in dem Längskanal 62 des Gehäuses 38 verschiebt. Wenn auf diese Weise die Metallkappe 58 geöffnet wurde, strömt das Druckgas, vorzugsweise CO2, durch den Längskanal 62 und über eine kurze Querbohrung 64 im Anschlußrohr 46 in dessen Längsbohrung 66, wodurch es in das Kissen 10 gelangt und dieses dabei aufbläst.In the housing 38, a needle 54 is slidably mounted in the longitudinal direction and can be pushed by the actuating lever 50 against the force of a compression spring 56 in the direction of the cartridge 52, so that the tip of the needle 54 has the end closed by a metal cap 58 the cartridge 42 opens. For this purpose, the lever 50 is pivoted into the position shown in dashed lines in FIG. 5, its short end 60 displacing the needle 54 in the longitudinal channel 62 of the housing 38. When the metal cap 58 has been opened in this way, the compressed gas, preferably CO2, flows through the longitudinal channel 62 and via a short transverse bore 64 in the connecting tube 46 in its longitudinal bore 66, as a result of which it enters the cushion 10 and inflates it.
Das dem Kissen 10 gegenüberliegende Ende der Längsbohrung 66 ist durch eine Schraube 68 verschlossen, die gleichzeitig zur Fixierung des Ventilgehäuses 38 auf dem Anschlußrohr 46 dient. Dichtringe 78 sorgen für einen druckdichten Abschluß.The end of the longitudinal bore 66 opposite the cushion 10 is closed by a screw 68, which at the same time serves to fix the valve housing 38 on the connecting pipe 46. Sealing rings 78 ensure a pressure-tight seal.
Ein derartiges Ventil 36 wird beispielsweise von der Firma Halkey-Roberts unter der Bezeichnung Series 840 hergestellt und vertrieben. Am freien Ende des Betätigungshebelε 50 ist eine Zugschnur 70 mit einem Griff 72 angebracht, die gemäß den Figuren 3 und 4 aus der Tasche 16 heraushängt. Wenn der Schwimmer das Kissen 10 auf¬ blasen möchte, genügt es, die Tasche 16 durch Aufreißen der Klettverschlußelemente 24 rasch zu öffnen und anschließend über die Zugschnur 70 den Betätigungshebel 50 in die in Figur 5 ge¬ strichelt eingezeichnete Stellung auszuschwenken, so daß das Druckgas aus der Patrone 42 in das Kissen 10 strömt und in die in Figur 4 gezeigte Stellung bringt.Such a valve 36 is manufactured and sold, for example, by the Halkey-Roberts company under the name Series 840. A pull cord 70 with a handle 72 is attached to the free end of the actuating lever 50 and hangs out of the pocket 16 according to FIGS. 3 and 4. If the swimmer wishes to inflate the cushion 10, it is sufficient to quickly open the pocket 16 by tearing open the Velcro fastener elements 24 and then to pivot the actuating lever 50 into the position shown in broken lines in FIG. 5 so that the compressed gas flows from the cartridge 42 into the cushion 10 and brings it into the position shown in FIG.
Figur 4 zeigt gestrichelt ein Band 74, das als zusätzliche Halterung am freien Ende des Kissens 10 angebracht und um den Nacken des Schwimmers gelegt werden kann. In aller Regel genügt es jedoch, das aufgeblasene Kissen 10 mit den Armen zu umschlingen, um dessen Lage unter der Brust zu stabilisieren und den gewünschten Auftrieb herbeizuführen.Figure 4 shows a dashed line 74, which can be attached as an additional holder to the free end of the pillow 10 and placed around the neck of the swimmer. As a rule, however, it is sufficient to wrap the inflated pillow 10 with the arms in order to stabilize its position under the breast and to bring about the desired buoyancy.
Bei einer Realisierung der Schwimmhilfe gemäß der Erfindung wurden zwei Größen für das aufgeblasene Kissen 10 untersucht. Mit einer Cθ2~Patrone 42 von 12 g Gasinhalt und einem Kissenvolumen von 7 1 wurde eine Auftriebskraft von 7 N erzielt; die zweite Variante (16 g Gas-Patrone und Kisεenvolumen 9 1) ergab eine Auftriebskraft von 9 N.In a realization of the buoyancy aid according to the invention, two sizes for the inflated cushion 10 were examined. With a CO 2 cartridge 42 of 12 g gas content and a cushion volume of 7 l, a buoyancy of 7 N was achieved; the second variant (16 g gas cartridge and cushion volume 9 1) gave a buoyancy of 9 N.
Nach dem Gebrauch kann das Kissen 10 wieder entleert und zusammengefaltet werden, so daß es für einen neuen Einsatz mit einer neuen Patrone 42 zur Verfügung steht. After use, the pillow 10 can be emptied and folded up again so that it is available for a new use with a new cartridge 42.
