Definitions

  • the invention relates to a folding anchor according to the preamble of claim 1.
  • Such an anchor is known for example from US-A-3 651 777.
  • 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.
  • 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.
  • 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.
  • this construction is extremely impractical to handle; this is especially true for collapsing the flunk after using the anchor.
  • 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.
  • 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.
  • Claims 2 to 5 relate to preferred structural details of the invention, which contribute to a functional and compact lightweight construction.
  • the anchor according to the invention presents itself as a (housing) construction which is closed towards the outside.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • a spring element axially acting in the form of a compression spring between the grip part 10 and the sleeve 7.
  • 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.
  • this solution carries the risk that the sleeve 7 accidentally slips into the release position when the anchor is thrown away.
  • 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.
  • 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.
  • the axial displaceability of the sleeve 7 serving as the anti-spark element is indicated in FIG. 1 by the double arrow 17.
  • the shaft 1.1 is designed overall as a club-like housing, the anchor described can be used particularly well as a throwing anchor.
