Abstract

The invention relates to a carabine swivel, especially one used for sea and air rescue, comprising a C-shaped swivel body whose opening is closed by a pivotable snap-to guide which is pivotable counter to the force of a spring in an area surrounded by the C-shaped swivel body. The aim of the invention is to provide a carbine swivel enabling a fitting to be hooked in without any additional movements such that reliable and rapid hooking in can occur, even in adverse conditions such as, for example, those during rescue at sea. The carabine swivel must also meet the strict requirements of test standards such that at least two different intentional actuations are required in order to open the carbine swivel. The invention consists in arranging an additional closure in the form of an additional snap-to guide which extends in an area surrounded by the swivel body from one longitudinal side of the swivel body to the other longitudinal side of the swivel body. Another carabine swivel is arranged inside the inventive carabine swivel. The additional snap-to guide acts as an additional closure which specifically closes one part of the inner area of the swivel independently from the first closure snap-to guide such that a formation is created consisting of a single swivel and two snap closures which can be actuated independently from each other.

Description

Karabinerhaken carabiner
Die Erfindung betrifft einen Karabinerhaken, insbesondere für Rettungszwecke zu Wasser und zu Luft, bestehend aus einem C-förmigen Hakenkörper, dessen Öffnung durch einen verschwenkbaren Schnapper verschlossen ist, der entgegen der Kraft einer Feder in den vom C-förmigen Hakenkörper umschlossenen Raum verschwenkbar ist.The invention relates to a snap hook, in particular for rescue purposes to water and air, consisting of a C-shaped hook body, the opening of which is closed by a pivotable catch which can be pivoted against the force of a spring into the space enclosed by the C-shaped hook body.
Karabinerhaken dieser Art sind hinlänglich bekannt. Im Einsatz für Rettungszwecke zu Wasser und zu Luft werden besondere Anforderungen an die Sicherung von Karabinerhaken gestellt. Um eine versehentliche Selbst- öfϊhung bzw. -entriegelung zu vermeiden muss die Nerschlussöfmung der Karabinerhaken mindestens zwei unterschiedliche absichtliche menschliche Betätigungen erfordern.Snap hooks of this type are well known. When used for rescue purposes on water and air, special requirements are placed on securing snap hooks. In order to avoid accidental self-opening or unlocking, the opening of the snap hooks must require at least two different deliberate human activities.
Ein diesen gesetzlichen Sicherheitsanforderungen gerecht werdender Karabinerhaken ist beispielsweise aus der DE 0069616077 T2 bekannt geworden, Die Öffnung des Karabinerhakens ist durch eine aus einem Schaft aus elastisch verformbaren Material gebildete Sperrklinke zu verschließen, die eine offene Schleife bildet. Diese wird in eine Aussparung eingelegt, die sich am gekrümmten Ende des Hakens befindet und wird durch einen am Körper des Karabinerhakens befindlichen Hebel zum Zweck des gesicherten Nerschließens verspannt. Eine weitere . rt der zweifachen Sicherung von Karabinerhaken ist es, den die Öffnung des Hakens verschließenden Schnapper in seiner Schließstellung zu verriegeln.A snap hook that meets these legal safety requirements has become known, for example, from DE 0069616077 T2. The opening of the snap hook is to be closed by a pawl formed from a shaft made of elastically deformable material, which forms an open loop. This is inserted into a recess which is located at the curved end of the hook and is clamped by a lever located on the body of the snap hook for the purpose of secure locking. Another . The double securing of snap hooks is to lock the snapper closing the opening of the hook in its closed position.
Hierzu wird auf eine auf dem Schnapper beweglich gelagerte Sicherungshülse mittels einer Führungseinrichtung auf die Übergangsstelle Hakenende/Schnapper geschoben und verriegelt. Als Verriegelungsarten werden u.a. Sicherungsmuttern auf Nerschlussbolzen, die Twist-Lock-Sicherung und die Screw-Lock-Sicherung angewendet.For this purpose, a locking sleeve movably mounted on the snapper is pushed and locked onto the transition point hook end / snapper by means of a guide device. Interlocking types include Locknuts applied to locking bolts, the twist-lock and the screw-lock.
Aus der DE 31 07 389 AI ist ein Karabinerhaken bekannt geworden, dessen Schnapper durch einen Arretierhebel gegen unbeabsichtigtes Öffnen gesichert ist. Der Arretierhebel ist an der der Hakenöffhung gegenüberliegenden Seite am Hakenkörper angelenkt und stützt sich mit seinem entgegen der Kraft einer Feder verschwenkbaren Ende an dem die Hakenöffhung verschließenden Schnapper ab. Zum Einführen eines Beschlages muss der Arretierhebel vom Benutzer mit einem ersten Handgriff verschwenkt werden, um dann in einem zweiten Handgriff den Beschlag in den Innenraum des Hakens einführen zu können.From DE 31 07 389 AI a snap hook has become known, the catch of which is secured against unintentional opening by a locking lever. The locking lever is articulated on the side opposite the hook opening on the hook body and, with its end pivotable against the force of a spring, is supported on the catch which closes the hook opening. To insert a fitting, the locking lever must be pivoted by the user with a first handle, in order then to be able to insert the fitting into the interior of the hook in a second handle.
Diese bekannten Karabinerhaken haben den Nachteil, dass mehrere Handgriffe zum Öffnen des Schnappers beim Einhaken erforderlich sind. Bei der Rettung, wie z.B. zu Wasser, sind die Bergungsumstände extrem durch die rauhen und widrigen Bedingungen bei Sturm, Seegang, Dunkelheit, Sichtbehinderung durch Wasser, Gischt und Schaum erschwert. Durch die starken Eigenbewegungen des Helfers im Seegang und einer damit fehlenden sicheren
Figure imgf000004_0001
und zusätzlich der Schutzkleidung (Überlebensanzug) des Helfers, die u.a. aus dicken Fäustlingen besteht, ist keine Wahrnehmung von kleineren Bauteilen am bekannten Sicherungskarabiner (Hebel, Rädchen, Rändelschrauben u.a.) möglich. Innerhalb solch vorbeschriebener Umstände sind feinmotorische Handgriffe so gut wie ausgeschlossen und dem Helfer enge Grenzen für differenzierte Handlungen gesetzt.These known snap hooks have the disadvantage that several handles are required to open the catch when hooking in. When rescuing, such as on water, the salvage conditions are extremely difficult due to the harsh and adverse conditions during storms, swell, darkness, water, spray and foam. Due to the strong self-movements of the helper in the sea and a lack of safe
Figure imgf000004_0001
and in addition to the protective clothing (survival suit) of the helper, which consists, among other things, of thick mittens, it is not possible to perceive smaller components on the known safety carabiner (lever, wheel, knurled screw etc.) Within the circumstances described above, fine motor movements are practically excluded and the helper is limited to differentiated actions.
Die Rettung von verunfallten Personen ist mit den bekannten Karabinerhaken nicht zuverlässig einsatzfahig und zudem sehr zeitaufwendig.The rescue of accident victims is not reliably usable with the known snap hooks and is also very time-consuming.
Es bedarf hierfür eines Karabiners, der sich nicht versehentlich vor dem geplanten Einsatz verriegeln und damit eine Rettung womöglich verhindern kann und es bedarf hierfür eines Karabiners, der nicht erst durch zusätzliche Handgriffe vom Helfer im oder unter Wasser gesichert werden muss. Beide Formen zusätzlicher Handgriffe sind dem Helfer wegen der ihm fehlenden sicheren Plattform und den widrigen Bedingungen im bewegten Wasser nicht möglich.This requires a carabiner that can not accidentally lock itself before the intended use and thus possibly prevent a rescue, and a carabiner that does not have to be secured by the helper in or under water with additional hand movements. Both forms of additional handles are not possible for the helper due to the lack of a secure platform and the adverse conditions in moving water.
Die Erfindung vermeidet die Nachteile des Standes der Technik. Es ist die Aufgabe der Erfindung, einen Karabinerhaken bereitzustellen, bei dem das Einhaken eines Beschlages keiner zusätzlichen Handgriffe bedarf, so dass ein Einhaken auch unter widrigen Bedingungen, wie bzw. bei der Seerettung, zuverlässig und ohne große Zeitverzögerung möglich ist. Der Karabinerhaken soll zusätzlich den strengen Anforderungen der Prüfnormen entsprechen, so dass zur Öffnung des Karabinerhakens mindestens zwei unterschiedliche absichtliche Betätigungen erforderlich sein sollen.The invention avoids the disadvantages of the prior art. It is the object of the invention to provide a snap hook in which the hooking in of a fitting does not require any additional manipulations, so that hooking in under adverse conditions, such as or during rescue at sea, is possible reliably and without a great time delay. The snap hook should also meet the strict requirements of the test standards, so that at least two different deliberate actions should be required to open the snap hook.
Die Erfindung besteht darin, einen zusätzlichen Verschluß in Form eines zusätzlichen Schnappers anzuordnen, der sich im vom Hakenkörper umschlossenen Raum von einer Längsseite des Hakenkörpers zur anderen Längsseite des Hakenkörpers erstreckt. Entgegen des bekanten Standes der Technik, bei dem eine zusätzliche Sicherung am Schnapper direkt angeordnet ist, wird bei dem Erfindungsgegenstand innerhalb des Karabinerhakeninnenraumes durch die Anordnung eines zweiten Schnappers ein zusätzlicher Sicherheitsbereich geschaffen. Die leichte Gängigkeit und Handhabe der Schnapper wird nicht durch Verriegelungen blockiert, die zum Öffnen oder Verschließen filigrane Handarbeit bedürfen. Ein Einhaken in den Karabiner ist auch bei widrigen Umständen problemlos und schnell möglich.The invention consists in arranging an additional closure in the form of an additional catch which extends in the space enclosed by the hook body from one long side of the hook body to the other long side of the hook body. Contrary to the known state of the art, in which an additional securing device is arranged directly on the snapper, an additional security area is created in the subject matter of the invention within the snap hook interior by the arrangement of a second snapper. The easy movement and handling of the snappers is not blocked by locks that require delicate manual work to open or close. Hooking into the carabiner is quick and easy, even in adverse conditions.
Es ist ein Karabinerhaken geschaffen, in dessen Innenraum ein weiterer Karabinerhaken angeordnet ist. Der zusätzliche Schnapper ist ein zusätzlicher Verschluss, der unabhängig vom ersten Verschlussschnapper einen Teil des Innenraumes des Hakens gesondert verschließt, so dass ein Gebilde aus einem einzigen Haken und zwei unabhängig voneinander zu betätigenden Schnappverschlüssen entstanden ist.A snap hook is created, in the interior of which another snap hook is arranged. The additional snapper is an additional fastener which, independently of the first fastener snapper, closes part of the interior of the hook separately, so that a structure is formed from a single hook and two snap fasteners which can be actuated independently of one another.
Besonders vorteilhaft ist es, wenn der weitere Schnapper oberhalb des ersten Schnappers derart angeordnet ist, dass er in Richtung der Hakenspitze verschwenkbar ist, aber dass die Verschwenkbarkeit in Richtung zum Hakenende blockiert ist, so dass ein Beschlag in einer einzigen Bewegung durch den Bereich (B) in den Bereich (A) einführbar ist und der Beschlag nicht ohne Zuhilfenahme einer Hand zur Verschwenkung des Schnappers aus dem Bereich entfernbar ist.It is particularly advantageous if the further snapper is arranged above the first snapper in such a way that it can be pivoted in the direction of the hook tip, but that the pivotability in the direction of the hook end is blocked, so that a fitting can move through the area (B ) can be inserted into area (A) and the fitting cannot be removed from the area without the aid of a hand for pivoting the catch.
Durch die Konstruktion des zusätzlichen Sicherheitsbereiches (A) besteht der Karabiner aus zwei nacheinander zu öffnenden Einzugsbereichen: dem üblichen Einzugsbereich (B) und dem zusätzlichen Sicherheitsbereich (A). Diese Anordnung der nacheinander zu öffnenden Bereiche erlaubt es, dass der einzuhakende Beschlag (Ring) ohne zeitliche Verzögerung durch Entriegelungen oder Verriegelungen des Schnappers in den ersten Hakenbereich eingezogen werden kann und anschließend durch weiteren Durchzug in der gleichen Zugrichtung den Schnapper des Sicherheitsbereichs von dessen Gelenk- oder Gegenseite her Öffnet.Due to the construction of the additional security area (A), the carabiner consists of two successive opening areas: the usual area (B) and the additional security area (A). This arrangement of the areas to be opened one after the other allows the fitting (ring) to be hooked in to the first without any delay by unlocking or locking the catch Hook area can be retracted and then opens the snapper of the security area from its hinge or opposite side by further pulling in the same direction of pull.
Die vorbeschriebene Ausgestaltung des Karabinerhakens ist besonders dann einfach und zuverlässig anwendbar, wenn die eine Längsseite des Hakenkörpers parallel zur Zugbeanspruchung (die während einer Benutzung auftritt) ausgerichtet ist, wenn die gegenüberliegende Längsseite in drei gerade verlaufende Abschnitte unterteilt ist, die im stumpfen Winkel aufeinander stehen, wobei innerhalb des am Hakenende angrenzenden Abschnittes der Schnapper und innerhalb des mittleren Abschnittes der Verschwenkpunkt des Schnappers angeordnet ist.The above-described design of the snap hook is particularly easy and reliable to use if the one long side of the hook body is aligned parallel to the tensile stress (which occurs during use), if the opposite long side is divided into three straight sections which are at an obtuse angle , wherein the snapper is arranged within the section adjoining the hook end and the pivot point of the snapper is arranged within the central section.
Diese Ausgestaltung ermöglicht die Aufiiahme der Zugspannung während des Bergevorganges von der Längsseite, an der keine Schnapperankoppelungen angeordnet sind. Die Schnapper sind daher auch während Phasen hoher Kraftbeanspruchung zu bedienen.This configuration enables the tensile stress to be recorded during the recovery process from the long side on which no snap couplings are arranged. The catches can therefore also be used during phases of high force.
Eine weitere Möglichkeit der Ausgestaltung besteht darin, dass ein Fangbügel in den Bereich (A) hineinragt, an dem der weitere Schnapper im Ruhezustand gelagert ist, dass der Fangbügel an derjenigen Längsseite des Hakens angeordnet ist, die der Längsseite gegenüberliegt, an der der weitere Schnapper verschwenkbar angekoppelt ist und dass der Fangbügel maximal eine Länge aufweist, bei der ein Beschlag bei geöffnetem Schnapper zwischen Fangbügel und Schnapper in den Bereich (A) einbringbar ist.A further possible embodiment is that a safety catch projects into area (A), on which the further snapper is mounted in the idle state, and that the safety catch is arranged on the long side of the hook that is opposite the long side on which the further snapper is located is pivotally coupled and that the safety catch has a maximum length at which a fitting can be inserted into area (A) between the safety catch and the catch when the catch is open.
Durch das Hineinragen des Fangbügels in den Bereich A, ist die von dem weiteren Schnapper zu verschließende Öffnung verkleinert worden. Die Länge des Schnappers kann derart ausgelegt werden, dass sie bei Verschwenkung die maximale Öffhungsgröße freigibt, indem der Schnapper an dem Längsseitenabschnitt parallel anliegt.By protruding the safety catch into area A, the opening to be closed by the further snapper has been reduced. The length of the snapper can be designed so that at Pivoting releases the maximum opening size by the snapper lying parallel to the long side section.
Möglich ist eine Ausgestaltung, bei der der Fangbügel und der im Ruhezustand befindliche Schnapper miteinander fluchten oder bei der am Ende des Hakenkörpers ein Vorsprung angeordnet ist. Der Vorsprung erschwert ein ungewolltes Herausrutschen des Beschlages, da der Schnapper entsprechend der Länge des Vorsprunges weiter geöffnet werden muss.A configuration is possible in which the safety catch and the catch which is in the idle state are aligned with one another or in which a projection is arranged at the end of the hook body. The projection makes it difficult for the fitting to slide out unintentionally, since the catch must be opened further in accordance with the length of the projection.
Der weitere Schnapper ist besonders dann einfach zu bedienen, wenn der weitere Schnapper an einer Längsseite an einem in den Innenbereich des Hakenkörpers hineinreichenden Vorsprung verschwenkbar angeordnet ist.The further snapper is particularly easy to use if the further snapper is pivotably arranged on one long side on a projection extending into the inner region of the hook body.
Zur Ankopplung weiterer Rettungsutensilien ist es vorteilhaft, wenn an der Hakenspitze und/oder an dem Hakenende Kausche oder Wirbelaugen zur Aufnahme von Beschlägen angeordnet sind.For coupling further rescue utensils, it is advantageous if thimbles or swivel eyes for receiving fittings are arranged on the hook tip and / or on the hook end.
Besonders vorteilhaft ist es, wenn am Ende des Hakenkörpers ein nach außen weisender Vorsprung angeordnet ist, der über den Umfang des Schnappers hinausreicht. Dieser ermöglicht bei widrigen Witterungsverhältnissen ein Ertasten der Stelle, an dem der Schnapper zu verschwenken ist und ermöglicht derart ein blindes Einführen des Beschlages in den Karabinerhakeninnenraum.It is particularly advantageous if an outwardly facing projection is arranged at the end of the hook body, which extends beyond the circumference of the catch. In adverse weather conditions, this makes it possible to feel where the snapper is to be pivoted and thus enables the fitting to be inserted blindly into the interior of the snap hook.
Zur Vermeidung von Verletzungen während der Verwendung des Karabinerhakens ist es von Vorteil, wenn die Oberflächen aus glatt bearbeitetem Material bestehen und dass dieser aus Material gefertigt ist, welches gut hautverträglich ist. Das Wesen der Erfindung ist nachstehend anhand des schematisch in der Zeichnung dargestellten Ausfuhrungsbeispieles näher erläutert: Der Karabinerhaken, insbesondere für Rettungszwecke zu Wasser und zu Luft, besteht aus einem Hakenkörper 1, der eine Hakenspitze la und ein gegenüberliegendes Hakenende lb aufweist. Am Hakenende lb ist ein entgegen der Kraft einer Feder in den Innenraum B verschwenkbarer Schnapper 2 angeordnet ist, der im Ruhezustand eine zwischen dem Hakenkörper 1 und dem Hakenende liegende Öffnung verschließt. jAm Hakenkörper 1 ist ein weiterer Schnapper 3 angeordnet, der im Ruhezustand eine Öffnung verschließt, die innerhalb des Hakenköipers 1 von einer Längsseite 4a zur gegenüberliegenden Längsseite 4b verläuft. Dieser Schnapper 3 ist ebenfalls entgegen der Kraft einer Feder zu verschwenken und zwar in Richtung der Karabinerhakenspitze la. Seine Bewegung in Richtung des Hakenendes lb durch ein Lager beschränkt, welches als ein Fangbügel 6 schräg in den Innenraum des Karabinerhakens hineinreicht. (Die geöffnete Stellung der Schnapper ist gestrichelt dargestellt.)To avoid injuries when using the snap hook, it is advantageous if the surfaces consist of smoothly processed material and that it is made of material that is well tolerated by the skin. The essence of the invention is explained in more detail below with reference to the exemplary embodiment shown schematically in the drawing: The snap hook, in particular for rescue purposes in water and in air, consists of a hook body 1 which has a hook tip 1 a and an opposite hook end 1 b. At the end of the hook 1b there is a catch 2 which can be pivoted into the interior B against the force of a spring and which, in the idle state, closes an opening lying between the hook body 1 and the end of the hook. jA further catch 3 is arranged on the hook body 1, which, in the idle state, closes an opening which runs within the hook body 1 from one longitudinal side 4a to the opposite longitudinal side 4b. This snap 3 is also to be pivoted against the force of a spring, namely in the direction of the snap hook tip la. Its movement in the direction of the hook end 1b is limited by a bearing which extends obliquely as a safety catch 6 into the interior of the snap hook. (The open position of the snappers is shown in dashed lines.)
Durch diese Anordnung der im Ruhezustand befindlichen Schnapper 3,4 sind innerhalb des Karabinerhakens zwei geschlossene Bereiche A,B entstanden. Zur Aufnahme von während der Rettung auftretenden Kräften ist die Form des Karabinerhakens 1 folgendermaßen augestaltet: Parallel der bei Gebrauch auftretenden Zugspannung 8 verläuft die Längsseite 4a, so dass die auftretenden Kräfte größtenteils von dieser gerade verlaufenden Längsseite 4a aufgenommen werden. Die gegenüberliegende Längsseite 4b ist in drei gerade verlaufende Abschnitte unterteilbar, die im stumpfen Winkel aufeinander stehen. Innerhalb des am Hakenende lb angrenzenden Abschnittes ist der Schnapper 2 und innerhalb des mittleren Abschnittes an einem Vorsprung 10 der Verschwenkpunkt 9 des weiteren Schnappers 3 angeordnet. Bei dem Einhängen eines Beschlages kann der Helfer oder der Verunglückte selber anhand eines ertastbaren Vorsprunges 5, der am Ende des Hakenkörpers angeordnet ist, die Lage des Schnappers 2 ertasten, den Beschlag in Richtung der Hakenspitze la einziehen, den Bereich B passieren und aufgrund der gleichen Zugbewegung den Beschlag durch Verschwenkung des Schnappers 3 in den Sicherheitsbereich A einbringen. Aus diesem Sicherheitsbereich A ist der Beschlag nur durch Verschwenkung des Schnappers 3 per Hand wieder in den Bereich B zu bringen, denn der Beschlag hat innerhalb dieses Bereiches keinen Angriffspunkt, um den Schnapper zu bewegen.As a result of this arrangement of the catches 3, 4 which are in the idle state, two closed regions A, B have arisen within the snap hook. The shape of the snap hook 1 is designed as follows to absorb forces occurring during the rescue: The longitudinal side 4a runs parallel to the tensile stress 8 which occurs during use, so that the occurring forces are largely absorbed by this straight longitudinal side 4a. The opposite longitudinal side 4b can be divided into three straight sections which are at an obtuse angle to one another. The catch 2 is arranged within the section adjoining the hook end 1b and the pivot point 9 of the further catch 3 is arranged on a projection 10 within the middle section. When attaching a fitting, the helper or the victim himself can feel the position of the catch 2 using a tactile projection 5 which is arranged at the end of the hook body, pull the fitting in the direction of the hook tip la, pass area B and because of the same Pull the fitting into the security area A by swiveling the catch 3. From this security area A, the fitting can only be brought back into area B by swiveling the catch 3 by hand, because the fitting has no point of attack within this area to move the catch.
Um den Beschlag aus dem Karabinerhaken herauszuführen sind zwei unterschiedliche absichtliche menschliche Betätigungen erforderlich. Zuerst muss der Schnapper 3 per Hand geöffnet werden, damit der Beschlag in den Bereich B überfuhrt werden. Um den Beschlag nun ausserhalb des Karabinerinnenraumes zu bringen bedarf es einer weiteren Öffnung des Schnappers 2 per Hand und der Führung des Ringes durch die äußere Öffnung des Karabinerhakens 1. Two different deliberate human operations are required to lead the fitting out of the snap hook. First, the snap 3 must be opened by hand so that the fitting can be transferred to area B. In order to bring the fitting outside the carabiner interior, a further opening of the catch 2 by hand and the guidance of the ring through the outer opening of the carabiner hook 1 are required.
