Definitions

  • the invention relates to a snap hook with a bracket having an insertion opening, and with a closure part spanning the opening, which is pivotally mounted inwardly at a first end of the bracket and is acted upon by a return spring against the second end of the bracket.
  • Such a snap hook can be found, for example, in WO-A 91/13264.
  • a blocking element which blocks the opening movement of the closure part and which can be moved into a release position by means of a handle.
  • the locking element is designed as a locking slide in the closure part, which has an outwardly projecting, button-like actuating handle.
  • the one which protrudes outwards is
  • the free end of the closure part and the opposite, second bow end have hooks which lie in one another with so much play that the closure part can be pivoted, but get caught under tensile load and thus prevent opening.
  • snap hooks should meet two different requirements. On the one hand, they should have an easily visible closure part, so that it when climbing it can be easily clipped into a rope or eyelet with one hand. The closure part should have no additional lock or locking. On the other hand, a snap hook hooked into a belt, a rope or an eyelet should mostly only be able to be opened consciously, in particular unintended operations by the rope or the like enclosed inside. as well as from external objects, such as feet, branches, etc.
  • the invention has now set itself the task of substantially reducing or practically eliminating the risk of unintentional opening in a snap hook of the type mentioned at the outset. Furthermore, the described double use should also be possible.
  • the handle is arranged within a recess so that it can be actuated by means of a fingertip.
  • the handle is thus countersunk in the recess so that an object touching the edge of the recess only touches the handle if a bulging projecting area is formed on the object.
  • Such a range is not given for ropes, belts, etc., so that under no circumstances can they operate the handle.
  • many other objects, such as the user's clothing, branches, rocky outcrops, etc. generally do not have a projection comparable to a fingertip. An unintentional opening is practically impossible.
  • the further object of the invention is achieved in that the closure part is arranged adjustably at the first end of the bracket between two closed positions.
  • the bearing pin of the closure part is adjustably arranged in the first end of the bracket.
  • the reverse is also conceivable, namely that the closure part is adjustable on the bearing pin.
  • the snap hook has two different basic positions for the closure part, which can be selected before use. The closure part can therefore be adjusted between a first position in which the closure part is blocked and a second position in which the closure part is evident.
  • eccentric sections can be provided on the bearing pin, which act as offset bearing areas.
  • Axially displaceable can also be two bearing pins which are arranged next to one another at a small distance and which are alternately connected to the first end of the bracket.
  • the bearing pin can preferably be displaced parallel to itself in a slot provided in the first end of the bracket.
  • the slot is preferably angled so that it has two end regions, which form the stops for the two positions, and a central region.
  • the free end of the closure part and the second bow end are provided with hooks which allow pivoting in and out due to a distance
  • the displacement path of the bearing pin is at least this distance between the hooks.
  • an adjustable resistance for the bearing pin is assigned to the central region of the slot.
  • the transfer between the two positions of the bearing pin is perceptible to the user and, if appropriate, also audible.
  • the adjustable resistance that can be overcome is achieved in that the slot in the central region is at a greater distance from the second end of the bracket than the bearing pin. As a result, the two bracket ends are slightly pulled together as the bearing pin passes through the central area and then spring back into the relaxed position.
  • the position of the closure part or the bearing pin in which the closure part is blocked is preferably secured by a locking element which can be moved from a locking position into a release division.
  • the locking element is pivotally mounted in the locking part and rests in the locking position at the first end of the bracket. Both positions of the locking element can be stable, but since the locking element is the bearing pin Secures only in the blocked closure part position, it is preferably provided that the locking element is acted upon by a return spring, so that it automatically returns to the locking position.
  • the placement and handling of the locking element in the closure part is facilitated if the locking element is formed by an angular piece pivotably mounted in the closure part, one leg of the angle piece representing the handle and the second leg representing the lock.
  • a single return spring is preferably provided for the pivoting back of the angle piece and the closure part, the pivoting of the closure part displacing the locking leg from the end of the clip after the release of the locking leg from the first end of the bracket and the return spring being further compressed.
  • the locking element can also be designed as a locking slide adjustable in the longitudinal direction.
  • the depression is trough-shaped, so that the opening size of the depression is as small as possible.
  • the handle can be an element which interacts with the locking element, but is not in one piece, for example in the manner of a push button which moves the locking element. If the handle is provided on a locking slide, the depression can be formed in particular on the outside of the closure part by a groove in which the handle can be displaced.
  • the snap hook can be used for climbing as well as for hang gliding and paragliding. For use on paragliding devices, the snap hook preferably has an approximately trapezoidal shape, in which the closure part represents a side leg.
  • projections pointing inwards near the cover leg and / or the base leg are provided at least on the side leg opposite the closure part, so that a guide gap is defined in each case.
  • Such projections are preferably also formed on the first bracket end carrying the pivot bearing and / or on the free end of the closure part. In the ironing area, i.e. in the interior of the snap hook, the straps in the guide gaps are separated.
  • FIG. 1 shows a first embodiment of the snap hook in the closed position with a partially cut closure part
  • FIG. 2 shows the snap hook according to FIG. 1 in the open position
  • FIGS. 3 to 5 show a second embodiment which can be used in particular as a mountaineer snap hook
  • FIG. 3 shows an unlocked closed position
  • FIG. 4 shows the open position
  • FIG. 5 shows a locked closed position
  • FIGS. 6 to 9 show a third embodiment which can be used in particular as a paraglider carabiner hook, where in FIG. 6 the unlocked closed position, in FIG. 7 the open position, in FIG. 8 a middle position between the two closed positions and in FIG. 9 the locked closed position.
  • a snap hook has an open bracket 1, the opening of which can be closed or closed by means of a pivotable closure part 5.
  • the snap hook has the shape of a trapezoid, the
  • Closure part 5 forms a first side leg, and its pivot axis is provided at a first end 6 of the bracket 1, which is bent up from the base leg 4.
  • the second end 7 of the bracket 1, which receives the free end of the closure part 5, is bent down from the cover leg 3, the second bracket end 7 and the free end of the closure part 5 being designed such that a positive connection is effective at high tensile loads, in particular tensile loads becomes.
  • the second strap end 7, which is chamfered inwards for easier insertion of a webbing or rope and has rounded surfaces that are as free as possible from obstacles, is provided with two approximately U-shaped recesses, which are symmetrical to the strap level on both sides of a central web 19.
  • the free end of the closure part 5 has an oblique longitudinal groove corresponding to the central web 19 and end hooks 45, 46 on both sides which pivot into the recesses on both sides of the central web 19.
  • a distance a is provided between the hooks 45, 46, which must be reduced to engage the hooks 45, 46.
  • the base leg 4 and the cover leg 3 are each bent inwards.
  • a first bar end 6 has a central web 13 that receives a bearing pin 8.
  • the closure part 5 is pivotally mounted on this, the bearing-side end of which extends in the bow plane
  • the longitudinal slot of the closure part 5 is further penetrated by a second pivot axis 16, on which a locking element 11 in the form of an angle piece having a slot 17 is mounted.
  • the slot 17 receives a leg spring 10 which is also mounted on the pivot axis 16 and which is supported on the one hand on the closure part 5 and on the other hand on the locking element 11 and serves as a return spring for the closure part 5.
  • the elbow serving as locking element 11 has two legs 12, 15, one leg of which serves as a support leg 15 and the second leg serves as a handle 12.
  • On the outside of the closure part 5 and thus on the outside of the snap hook is a trough-like
  • Indentation 9 is provided, within which the handle 12 can only be actuated intentionally with a fingertip 30, but not accidentally struck by a rope, belt or other object, since the object cannot penetrate into the indentation 9.
  • the center web 13 extends further on the inside of the bracket beyond the bearing pin 8 than on the outside and there has a support or contact surface 14 for the support leg 15 of the locking element 11.
  • the closure part 5 cannot be pivoted as long as the support leg 15 of the locking element 11, under the action of the leg spring 10, presses against the support surface 14, its distance from the second Pivot axis 16 becomes lower. If the handle 12 sunk in the recess 9 is pressed with the fingertip 30, the locking element 11 pivots about the pivot axis 16, so that the support leg 15 moves away from the support surface 14 and the closure part 5 is pivoted inward into the bracket 1, that is to say opened can be (Fig. 2). The locking element 11 slides on the inner end region of the central web 13, the leg spring 10 being further compressed, so that after the insertion of a rope or belt into the rabbit hook, the locking part 5 into the closed position and then the locking element 11 into the locking position leads back.
  • the first end 6 of the bracket 1, the second side leg 2 opposite the closure part 5 and the free end of the closure part 5 each have an inward projection 20,21,22,23, so that near the base leg 4 and a guide gap 24 Cover leg 3 a guide gap 25 is defined.
