Description

Die Erfindung betrifft einen Faltanker gemaß dem Oberbegriff des Anspruches 1.The invention relates to a folding anchor according to the preamble of claim 1.

Ein derartiger Anker ist z.B. aus der US-A-3 651 777 bekannt. Dort ist als Sperrelement eine die freien Enden bzw. Spitzen der Flunken umschließende Kappe ausgebildet, die lediglich durch die Spreizkraft der Flunken in Flunken-Sperrstellung gehalten wird. Dies bedeutet, daß die Kappe schon bei geringstem Zug auf die mit der Kappe verbundene Ankerleine in Flunken-Freigabestellung rutscht, so daß die Flunken aus ihrer am Ankerschaft angelegten Stellung heraus in eine kreuzförmig auseinandergespreizte Stellung klappen, und zwar bedingt durch ein elastisches Spreizorgan in Form eines die fußseitigen Flunkenenden umschließenden Gummi- oder dgl. -rings. Ein zusätzliches Halteelement oder dergleichen zur Unterstützung der von den Flunken hervorgerufenen Spreizkraft, das die Freigabe der Flunken durch die Kappe zusätzlich erschwert, ist hingegen nicht vorhanden. Diese Konstruktion birgt somit die Gefahr in sich, daß bei Verwendung des Ankers als Wurfanker die Flunken schon während des Fluges auseinanderklappen. Dadurch gerät der Anker aus seiner gewünschten Flugbahn. Er wird ferner abgebremst. Die Reichweite und Zielgenauigkeit eines solchermaßen ausgebildeten (Wurf-)ankers läßt demnach zu wünschen übrig. Des weiteren ist der Fuß des bekannten Ankers topfartig ausgebildet, wobei das erwähnte elastische Spreizorgan, d.h. der Flunken-Spreizring, innerhalb des topfförmigen Fußes wirksam ist. Obenseitig ist der topfartige Fuß offen und somit für Schmutz, d. h. Schlick, Sand oder dgl. zugänglich. Bei etwas stärkerer Verschmutzung des topfförmigen Fußes, d. h. nach Zusetzen desselben mit Schlick etc. besteht daher die Gefahr, daß die Flunkenbewegung beeinträchtigt und der Anker entsprechend unwirksam wird. Im übrigen ist diese Konstruktion hinsichtlich ihrer Handhabung äußerst unpraktisch; dies gilt insbesondere für das Zusammenklappen der Flunken nach dem Gebrauch des Ankers.Such an anchor is known for example from US-A-3 651 777. There, a cap enclosing the free ends or tips of the flunk is formed as a blocking element, which is held in the flunk blocking position only by the spreading force of the flunk. This means that the cap slips on the anchor line connected to the cap in the floating release position even with the slightest pull, so that the flaps fold out of their position on the anchor shaft into a cross-shaped spread position, due to an elastic spreading element in the form a rubber ring or the like enclosing the foot-side sparkling ends. An additional holding element or the like to support the spreading force caused by the sparks, which additionally complicates the release of the sparks by the cap, is not available. This construction thus harbors the danger that when using the anchor as a throwing anchor, the sparks fold apart during flight. This causes the anchor to lose its desired trajectory. It is also slowed down. The range and accuracy of an anchor trained in this way leaves much to be desired. Furthermore, the base of the known anchor is pot-shaped, the elastic expansion element mentioned, ie the spunk expansion ring, being effective within the cup-shaped base. The pot-like foot is open on the top and thus accessible for dirt, ie silt, sand or the like. If the pot-shaped foot is somewhat heavier soiled, ie after it has been clogged with silt, etc., there is therefore a risk that the movement of the sparks will be impaired and the anchor will accordingly become ineffective. Incidentally, this construction is extremely impractical to handle; this is especially true for collapsing the flunk after using the anchor.

Ganz ähnlich verhält es sich auch bei dem Anker nach der US-A-3 793 977. Dieser Anker umfaßt als Sperrelement einen die freien Enden bzw. Spitzen der Flunken umgreifenden Ring, der ausschließlich mittels einer durch die Spreizkraft der Flunken erzeugten Reibkraft oder dergleichen in Flunken-Sperrstellung arretierbar ist. Dies hat zur Folge, daß der Ring bereits bei geringstem Zug über die mit dem Ring verbundene Ankerleine von den Enden bzw. Spitzen der Flunken gezogen und somit in die Flunken-Freigabestellung verbraucht wird. Ein gesondertes Halteelement oder dergleichen zum erschwerten Abziehen des Ringes ist darüber hinaus nicht vorgesehen. Dort besteht zudem die große Gefahr, daß das fußseitig angeordnete elastische Spreizorgan, d.h. die Flunken-Spreizfedern, beim Aufprall des Ankers auf einen Untergrund beschädigt werden. Eine sie schützende Abdeckung fehlt.The situation is similar in the case of the anchor according to US Pat. No. 3,793,977. This anchor comprises, as a blocking element, a ring encompassing the free ends or tips of the sparks, which ring is produced exclusively by means of a frictional force or the like generated by the sparks' spreading force Flunken blocking position can be locked. The result of this is that the ring is pulled from the ends or tips of the flukes at the slightest pull over the anchor line connected to the ring and is thus consumed in the flunk release position. A separate holding element or the like for making the ring difficult to remove is also not provided. There is also the great risk that the elastic expansion element arranged on the foot side, i.e. the sparks spreading springs, are damaged when the anchor hits a surface. A protective cover is missing.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, einen Anker der genannten Art zu schaffen, der sich durch kontrollierten Ruck an der Ankerleine am oder kurz vor dem Zielort ohne die Gefahr eines vorzeitigen Auseinanderklappens der Flunken beim Wurf bzw. während des Fluges durch die Luft spontan öffnet, konstruktiv einfach, kompakt, nach außen geschlossen und dementsprechend das elastische Flunken-Spreizorgan schützend ausgestaltet sowie leicht handhabbar ist.The present invention is therefore based on the object of creating an anchor of the type mentioned, which can be controlled by a controlled jerk on the anchor line at or shortly before the destination without the risk of the flaps unfolding prematurely when being thrown or during the flight through the air opens, is structurally simple, compact, closed to the outside and, accordingly, the elastic flunk spreader is designed to be protective and easy to handle.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.This object is achieved by the characterizing features of claim 1.

Erfindungsgemäß muß also eine vorgegebene bzw. voreingestellte Kraft überwunden werden, um das Flunken-Sperrelement in die Flunken-Freigabestellung zu bringen. Vorzugsweise erfolgt dies durch Anordnung einer Kugelrastsperre zwischen Flunken-Sperrelement und Ankerkörper, insbesondere Ankerschaft. Die Flunken lassen sich daher durch kontrollierten Zug auf die Ankerleine bzw. Ruck an der Ankerleine in Spreizstellung klappen.According to the invention, a predetermined or preset force must therefore be overcome in order to bring the anti-lock element into the anti-lock position. This is preferably done by arranging a ball detent between the anti-lock element and anchor body, in particular anchor shaft. The sparks can therefore be folded into the spread position by a controlled pull on the anchor line or by pulling on the anchor line.

Die Ansprüche 2 bis 5 betreffen bevorzugte konstruktive Details der Erfindung, die zu einer funktionsgerechten und kompakten Leichtbauweise beitragen.Claims 2 to 5 relate to preferred structural details of the invention, which contribute to a functional and compact lightweight construction.

Durch die Maßnahmen nach Anspruch 6 stellt sich der erfindungsgemäße Anker als eine nach außen hin geschlossene (Gehäuse-)konstruktion dar. Innerhalb des Schaftgehäuses ist das zentrale Flunken-Spreizelement vor Schmutz und Stößen geschützt angeordnet. Gemäß Anspruch 7 ist dieses darüber hinaus in einfacher Weise hinsichtlich seiner Härte einstellbar.Due to the measures according to claim 6, the anchor according to the invention presents itself as a (housing) construction which is closed towards the outside. Within the shaft housing, the central spreader spreader element is arranged so as to be protected from dirt and impacts. According to claim 7, this is also adjustable in terms of its hardness.

Der in den Fig. 1 und 2 dargestellte Faltanker 1 weist vier am Fuß 1.3 eines zentralen Schaftes 1.1 kreuzförmig angelenkte (Schwenkachsen 3) Flunken 2 auf. Diese sind entgegen der Wirkung eines weiter unten noch näher beschriebenen zentralen, elastischen Spreizorgans 4,5,6 nach Art eines Schirms nach innen an den Schaft 1.1 des Ankers anlegbar und in dieser Stellung entsprechend den Fig. 1 und 2 mittels eines am Schaft 1.1 längsverschieblich angeordneten Sperrelements in Form einer Hülse 7 fixierbar. Der in Fig. 1 obere bzw. dem Fuß 1.3 entgegengesetzte Abschnitt des Schaftes 1.1 ist rohrförmig ausgebildet und endseitig mit einem Griffteil 10 versehen. Durch den rohrförmigen Schaftabschnitt hindurch erstreckt sich eine steife Verbindung, und zwar in Form eines U-förmigen Verbindungsbügels 8, zwischen der am Schaft 1.1 längsverschieblich gelagerten Hülse 7 und einem Auge 9 zum Anschluß einer nichtdargestellten Ankerleine. Das Auge 9 ist an der oberen Umlenkung des Verbindungsbügels 8 angeformt, vorzugsweise auch angeschweißt (s. Fig. 4). Die Verbindung zwischen der Hülse 7 und den beiden Schenkeln des Verbindungsbügels 8 erfolgt mittels Klemmschrauben 19, die sich quer durch nicht näher dargestellte axial am rohrförmigen Schaftabschnitt ausgebildete Langlöcher hindurcherstrecken. Die obere, d. h. dem Fuß 1.3 des Schaftes 1.1 entgegengesetzte Stirnseite des oberen rohrförmigen Schaftabschnittes ist durch eine diesen abschließende Platte 11 geschlossen. Die Befestigung der Platte 11 am Schaft 1.1 erfolgt mittels einer oder mehrerer Schrauben 12. Die Platte 11 weist zwei Bohrungen für den gleitenden Durchtritt der beiden Schenkel des U-förmigen Verbindungsbügels 8 auf. Demnach dient die Platte 11 zugleich als Axialführung für den Verbindungsbügel 8 und dementsprechend für das Auge 9 in fester Zuordnung zur axial verschieblichen Hülse 7, mittels der die Flunken 2 in Anlage am Schaft 1.1 fixierbar sind.The folding anchor 1 shown in FIGS. 1 and 2 has four (2) axes 2 which are articulated in a cross shape at the foot 1.3 of a central shaft 1.1. Contrary to the effect of a central, elastic spreading member 4, 5, 6, which will be described in more detail below, they can be placed inward on the shaft 1.1 of the armature in the manner of a screen and, in this position, can be moved longitudinally in accordance with FIGS. 1 and 2 by means of a on the shaft 1.1 arranged locking element in the form of a sleeve 7 fixable. The upper portion of the shaft 1.1 in FIG. 1 or opposite the foot 1.3 is tubular and is provided with a grip part 10 at the end. A rigid connection extends through the tubular shaft section, in the form of a U-shaped connecting bracket 8, between the sleeve 7, which is mounted on the shaft 1.1 in a longitudinally displaceable manner, and an eye 9 for connecting an anchor line (not shown). The eye 9 is molded onto the upper deflection of the connecting bracket 8, preferably also welded on (see FIG. 4). The connection between the sleeve 7 and the two legs of the connecting bracket 8 takes place by means of clamping screws 19 which extend transversely through elongated holes not shown axially formed on the tubular shaft section. The upper one, ie the foot 1.3 The face of the upper tubular shaft section opposite the shaft 1.1 is closed by a plate 11 which closes the latter. The plate 11 is fastened to the shaft 1.1 by means of one or more screws 12. The plate 11 has two bores for the sliding passage of the two legs of the U-shaped connecting bracket 8. Accordingly, the plate 11 also serves as an axial guide for the connecting bracket 8 and accordingly for the eye 9 in a fixed association with the axially displaceable sleeve 7, by means of which the sparks 2 can be fixed in contact with the shaft 1.1.

Die Hülse 7 ist, wie Fig. 1 erkennen läßt, entgegen der Wirkung eines elastischen Elements, nämlich einer federbelasteten Kugelrastsperre 13,14,15 durch Ausübung von Zug auf das Auge 9 nach oben bzw. durch Ausübung eines entsprechenden Rucks an der am Auge 9 angeschlossenen Anker eine relativ zum Schaft 1.1 des Ankers nach oben bzw. vom Fuß 1.3 des Schaftes 1.1 weg verschiebbar, wodurch die freien Enden der am Schaft 1.1 angelegten Flunken 2 freikommen. Die Flunken 2 können dann auseinanderklappen unter Bildung eines Flunkenkreuzes. Das Auseinanderklappen der Flunken 2 in eine in Fig. 1 gestrichelt angedeutete, sich etwa senkrecht oder nahezu senkrecht zum Schaft 1.1 erstreckende Lage erfolgt durch ein auf die Flunken 2 zentral wirksames Federelement, nämlich eine axial wirksame Druckfeder 4, z.B. eine Schraubendruckfeder, die in eine am unteren Ende des Fußes 1.3 ausgebildete Axialbohrung einsetzbar und in dieser mittels einer Schraube 5 gehalten ist. Die Übertragung der Federkraft auf die Flunken 2 erfolgt über einen Druckteller 6, der mittels eines angeformten Zentrierstiftes 6.1 innerhalb der Druckfeder 4 festgelegt ist (s. Fig. 3). Der Druckteller 6 wirkt auf fußseitig angeordnete Vorsprünge 2.1 der Flunken 2, die relativ zu den Schwenkachsen 3 der Flunken 2 jeweils diametral zu den freien, mit der Hülse 7 zusammenwirkenden Enden der Flunken 2 ausgebildet sind.1, contrary to the action of an elastic element, namely a spring-loaded ball detent 13, 14, 15, by pulling the eye 9 upwards or by exercising a corresponding jerk on the eye 9 connected anchors a relative to the shaft 1.1 of the armature upwards or from the foot 1.3 of the shaft 1.1 away, whereby the free ends of the flanks 2 placed on the shaft 1.1 are released. The sparks 2 can then unfold to form a spider cross. The unfolding of the flukes 2 into a position indicated in dashed lines in FIG. 1 and extending approximately perpendicularly or almost perpendicularly to the shaft 1.1 takes place by means of a spring element acting centrally on the flunk 2, namely an axially active compression spring 4, for example a helical compression spring, which is inserted into a Axial bore formed at the lower end of the foot 1.3 can be used and is held therein by means of a screw 5. The spring force is transmitted to the flukes 2 via a pressure plate 6, which is fixed within the compression spring 4 by means of a molded-on centering pin 6.1 (see FIG. 3). The pressure plate 6 acts on the foot-side projections 2.1 of the flukes 2, which are each formed diametrically relative to the pivot axes 3 of the flunk 2 in relation to the free ends of the flanks 2 which cooperate with the sleeve 7.

Wie der Fig. 1 des weiteren entnommen werden kann, ist der Fuß 1.3 des Schaftes 1.1 zylindertopfartig ausgebildet mit einem Durchmesser, der großer ist als der Durchmesser des oberen rohrförmigen Schaftabschnitts. Demnach ist im Bereich des Fußes 1.3 genügend Raum zur schützenden Aufnahme von Druckfeder 4, Druckteller 6, Schwenkachsen der Flunken 2 3 und der Vorsprünge 2.1 an den fußseitigen Enden der Flunken 2 vorhanden. Der untere Schaftabschnitt 1.2 zwischen dem Fuß 1.3 und dem oberen rohrförmigen Schaftabschnitt ist kegelstumpfförmig ausgebildet. Am Außenumfang des kegelstumpfförmigen Schaftabschnitts 1.2 sind entsprechend der Anzahl der Flunken 2 Längsnuten ausgebildet, die zur zumindest teilweisen Aufnahme der Flunken 2 in am Schaft 1.1 angelegter Stellung dienen (s. Fig. 1 und 2). Durch diese teilweise versenkte Anordnung der Flunken 2 im Schaftabschnitt 1.2 erhält man einen äußerst kompakten Wurfkörper.As can also be seen in FIG. 1, the foot 1.3 of the shaft 1.1 is designed like a cylinder pot with a diameter that is larger than the diameter of the upper tubular shaft section. Accordingly, there is sufficient space in the area of the foot 1.3 for the protective reception of the compression spring 4, pressure plate 6, pivot axes of the flunk 2 3 and the projections 2.1 at the foot ends of the flunk 2. The lower shaft section 1.2 between the foot 1.3 and the upper tubular shaft section is frustoconical. On the outer circumference of the frustoconical shaft section 1.2, 2 longitudinal grooves are formed corresponding to the number of the sparks, which are used to at least partially accommodate the sparks 2 in the position applied to the shaft 1.1 (see FIGS. 1 and 2). This partially recessed arrangement of the sparks 2 in the shaft section 1.2 results in an extremely compact projectile.

Der innere, dem Fuß 1.3 zugewandte Umfangsrand 18 der Hülse 7 ist in Richtung nach unten konisch erweitert ausgebildet, und zwar in Anpassung an eine komplementär ausgebildete Abschrägung an den freien Enden der Flunken 2. Durch diese Konfiguration "springt" die Hülse 7 nach Überwindung der Kugelrastsperre 13,14,15 regelrecht spontan in die Flunken-Freigabestellung. Die axiale Verschiebung der Hülse 7 in ihre Freigabestellung ist begrenzt durch den Griffteil 10 bzw. einen fußseitigen Umfangswulst desselben.The inner circumferential edge 18 of the sleeve 7 facing the foot 1.3 is flared in the downward direction, in adaptation to a complementary bevel at the free ends of the sparks 2. This configuration "jumps" the sleeve 7 after overcoming the Ball lock 13,14,15 literally spontaneously in the flunk release position. The axial displacement of the sleeve 7 into its release position is limited by the handle part 10 or a circumferential bead on the foot side thereof.

Statt der Kugelrastsperre 13,14,15 kann die Hülse 7 auch durch ein zwischen Griffteil 10 und Hülse 7 (axial) wirksames Federelement in Form einer Druckfeder in Flunken-Schließstellung gehalten werden. Bei auf dem Schaft 1.1 axial verschiebbarem Griffteil 10 wäre es grundsätzlich auch denkbar, zwischen diesem und der Platte 11 ein axial wirksames Federelement in Form einer Druckfeder anzuordnen, so daß die Hülse 7 über dem Griffteil 10 in Schließstellung gehalten wird. Diese Lösung birgt jedoch die Gefahr in sich, daß die Hülse 7 beim Wegschleudern des Ankers versehentlich in die Flunken-Freigabestellung rutscht.Instead of the ball detent 13, 14, 15, the sleeve 7 can also be held in the closed-closed position by a spring element (axially) acting in the form of a compression spring between the grip part 10 and the sleeve 7. When the handle part 10 is axially displaceable on the shaft 1.1, it would in principle also be conceivable to arrange an axially effective spring element in the form of a compression spring between the latter and the plate 11, so that the sleeve 7 is held in the closed position above the handle part 10. However, this solution carries the risk that the sleeve 7 accidentally slips into the release position when the anchor is thrown away.

Bei den beiden letztgenannten Ausführungen ist es auch etwas schwieriger, nach Gebrauch des Ankers die Hülse 7 über die freien Enden der Flunken 2 zu schieben, da zu diesem Zweck die Hülse 7 entgegen der erwähnten Druckfeder axial nach oben verschoben werden muß. Gleichzeitig müssen der Schaft 1.1 festgehalten und die Flunken 2 nach innen in Anlage an den Schaft 1.1 geklappt werden. Diese Schwierigkeiten lassen sich mit der beschriebenen Kugelrastsperre 13,14,15 ohne weiteres vermeiden.In the latter two versions, it is also somewhat more difficult to push the sleeve 7 over the free ends of the flukes 2 after use of the armature, since for this purpose the sleeve 7 has to be displaced axially upwards against the compression spring mentioned. At the same time, the shaft 1.1 must be held in place and the flukes 2 folded inwards against the shaft 1.1. These difficulties can easily be avoided with the described ball detent 13, 14, 15.

Die beschriebene, zentral wirksame Druckfeder 4 mit Druckteller 6 hat gegenüber den bekannten Konstruktionen auch noch den großen Vorteil, daß beim Anlegen nur einer einzigen Flunke 2 an den Schaft 1.1 alle übrigen Flunken "drucklos" werden, d. h. ohne Überwindung der durch die Druckfeder bedingten Spreizkraft gegen den Schaft 1.1 geklappt werden können. Die Handhabung des beschriebenen Ankers ist also wesentlich einfacher als die des Ankers z. B. gemäß der US-A 3 793 977, bei dem jeder Faltflunke ein gesondertes Spreizelement zugeordnet ist, oder gemäß der US-A 3 651 777, bei dem durch das Einklappen einer Flunke die Spreizkraft auf die übrigen Flunken sogar erhöht wird, also genau der gegenteilige Effekt eintritt wie bei der beschriebenen Ausführungsform.The described, centrally effective compression spring 4 with pressure plate 6 also has the great advantage over the known constructions that when only a single fluke 2 is applied to the shaft 1.1, all other fluids are "depressurized", ie. H. can be folded against the shaft 1.1 without overcoming the spreading force caused by the compression spring. The handling of the anchor described is much easier than that of the anchor z. B. according to US-A 3 793 977, in which each folding hawk is assigned a separate spreading element, or according to US-A 3 651 777, in which the spreading force on the other flunks is even increased by folding in a hawk, that is to say exactly the opposite effect occurs as in the described embodiment.

Die erwähnte Kugelrastsperre 13,14,15 ist entsprechend Fig. 1 durch eine Querbohrung in der Hülse 7, eine in diese eingesetzte und mit einer komplementären Vertiefung am Außenumfang des rohrförmigen Abschnitts des Schaftes 1.1 zusammenwirkende Rastkugel 13 und eine auf diese wirkende Druckfeder 14 gebildet, welche durch eine in die Querbohrung von außen eingesetzte Schraube 15 gehalten ist. Durch die Schraube 15 ist die Federkraft auf die Rastkugel 13 einstellbar; ähnlich erfolgt im übrigen die Einstellung der Druckfeder 4 durch die Schraube 5.The aforementioned ball detent 13, 14, 15 is formed according to FIG. 1 by a transverse bore in the sleeve 7, a detent ball 13 inserted therein and interacting with a complementary recess on the outer circumference of the tubular section of the shaft 1.1, and a compression spring 14 acting thereon, which is held by a screw 15 inserted into the transverse bore from the outside. The spring force on the locking ball 13 can be adjusted by the screw 15; Similarly, the setting of the compression spring 4 is carried out the screw 5.

Unter Bezugnahme auf Fig. 1 sei noch erwähnt, daß die Spreizung bzw. das Auseinanderklappen der Flunken 2 durch gehäuseseitige Anschläge 16 begrenzt ist.With reference to FIG. 1, it should also be mentioned that the spreading or the unfolding of the sparks 2 is limited by stops 16 on the housing side.

Die Axialverschieblichkeit der als Flunken-Sperrelement dienenden Hülse 7 ist in Fig. 1 mit dem Doppelpfeil 17 angedeutet.The axial displaceability of the sleeve 7 serving as the anti-spark element is indicated in FIG. 1 by the double arrow 17.

Da der Schaft 1.1 insgesamt als keulenartiges Gehäuse ausgebildet ist, läßt sich der beschriebene Anker besonders gut als Wurfanker verwenden.Since the shaft 1.1 is designed overall as a club-like housing, the anchor described can be used particularly well as a throwing anchor.

Claims (7)

  1. Folding anchor having at least three flukes (2) which are articulated on the foot (1.3) of a central shank (1.1) and can be moved against the action of a flexible spreading member (4, 5, 6) in the manner of an umbrella inwards against the shank (1.1) and can be fixed in this position by means of a sleeve (7) arranged longitudinally displaceably on the shank (1.1) and engaging at least partially over the tips of the flukes, an anchoring or casting line being connected to the sleeve (7), so that by exerting a jerk on the line the sleeve (7) can be brought into a position releasing the flukes (2), characterised in that the sleeve (7) can be brought into the fluke-releasing position against the action of a further flexible element (13, 14, 15), which is independent of the flexible spreading member (4, 5, 6) acting on the flukes (2).
  2. Folding anchor according to Claim 1, characterised in that the sleeve (7) is held in the fluke-blocking position by a ball catch (13, 14, 15) which interacts with the shank (1.1) and/or by a spring element acting in the longitudinal direction of the shank.
  3. Folding anchor according to Claim 1 or 2, characterised in that the inner circumferential edge (18) of the sleeve (7), facing the foot (1.3) of the shank (1.1) and interacting with the free ends of the flukes (2), is designed as widened conically in the direction outwards and towards the foot (1.3) of the shank (1.1).
  4. Folding anchor according to one of Claims 1 to 3, characterised in that the upper shank section, opposite the foot (1.3) of the shank (1.1), is of a tubular design and is provided at the end with a grip part (10), there extending through the tubular shank section a rigid connection, in particular in the form of a U-shaped connecting bow (8), between the sleeve (7), displaceable back and forth on the tubular shank section, and an eye (9) for the connection of the anchoring line.
  5. Folding anchor according to Claim 4, characterised in that the shank (1.1) comprises between its preferably cylindrical pot-shaped foot (1.3) and its upper tubular shank section a lower shank section (1.2), extending conically in the direction of the foot (1.3), which lower section has on the outer circumference longitudinal grooves for at least partially receiving the flukes (2) folded against the shank (1.1).
  6. Folding anchor according to one of Claims 1 to 5, characterised in that the flukes (2) are prestressed into the fluke-spreading position by a compression spring (4) which is arranged centrally in the foot (1.3) of the shank (1.1) and acts axially, the compression spring (4) preferably acting via a pressure disc (6) evenly on the flukes (2), in particular projections (2.1) formed thereupon at the foot and extending radially inwards.
