The invention relates to a snap hook comprising a bracket having an insertion opening, the first and second ends limiting the insertion, a closing part, which assumes a closed position in the closed state of the snap hook, in which the closing part closes the insertion opening, wherein first and second ends of the closing part are in engagement with the first and second ends of the bow, and the swiveling axis opposite the bow is pivotable into a first open position for opening the snap hook about a pivotal axis formed in the area of the mutually engaging first ends of the bow and closing part second end of the closing part in the region of a surrounded by the bracket and closing part in the closed state of the snap hook interior of the snap hook moves, and an actuating arm which holds the closing part in its closed position in an initial position and the Öff NEN of the snap hook is adjustable.
A snap hook of this kind is evident from EP 1 229 258 A2. The actuating arm is mounted with its first end to a portion of the bracket opposite the insertion opening. Its second end is in operative connection with the closing part, for example by passing through a slot-shaped opening in the closing part. About this second end of the closing part in the open position pivoting tensile force is exercised upon actuation of the actuating arm on the closing part.
From FR 2 536 805 A1, a snap hook is shown, which has a locking bolt to secure the closing part against unintentional opening. This locking bolt is pivotally mounted on a portion of the bracket opposite the insertion opening. In its default position given by spring preload, its free end bears against the inside of the closing part and prevents pivoting of the closing part inwards. After pivoting the locking bolt, the closing part can be pivoted inwards and the snap hooks are opened. Further snap hooks of this type are disclosed in FR 2 439 330 A and FR 2 485 658 A.
DE 19839853 A1 shows a snap hook, which has a movement space of a hinged object, in particular rope, limiting element. This should be avoided cross-loads of the snap hook, which could lead to breakage of the carabiner. This the movement space limiting element extends in the region between the closing part and the opposite part of the closing part of the bracket, for example, it is mounted on the back portion of the bracket swivel-bar and is located with its free end on the closing part.
Snap hooks with lock bars which are adjustably mounted on or in the closing part and secure the carabiner in the closed state can be seen, for example, in WO 91/13264 and AT 400976 B.
The object of the invention is to provide a snap hook of the type mentioned with extended function. According to the invention, this is achieved by a snap hook with the features of claim 1.
When the carabiner hook of the invention, the closure member can be placed in two different open positions, wherein it is pivoted about different pivot axes. In the first open position, the closing part is pivoted about a pivot axis which is formed by the mutually engaging first ends of the bracket and the closing part. The second ends of the bracket and the closing part, which are in the closed position of the closing part, in which the snap hook is closed, are engaged, are thereby disengaged during pivoting of the closing part about this pivot axis. In the second open position of the closing part, the closing part is pivoted about a pivot axis which is formed by the mutually engaging second ends of the bracket and the closing part. When pivoting the closing part, starting from its closed position into its second open position, the first ends of the bow and closing part which are in engagement in the closed position are disengaged.
In the closed state of the snap hook, in which the closing part is in its closed position, the actuating arm assumes a starting position. In this initial position, the actuating arm supports the closure member against pivoting about both the pivotal axis formed by the engaged first ends of the striker and the bracket and about the pivot axis formed by the engaged second ends of the striker and bracket the first «· f · * * · f · ···« • I «» * * · · · · «

Ends of the strap and the closing part and the second ends of the strap and closing part in each case with each other. The actuating arm is adjustable starting from its central position in the direction of a first end position or in the direction of a second end position. This adjustment can be done by pivoting and / or displacement of the actuating arm as a whole or by a bend of the actuating arm. The Verschwenkungen or displacements or bending done here in the adjustments in the direction of the first and in the direction of the second end position in opposite directions.
Advantageously, when the actuating arm is moved into the first end position or into the second end position, it not only releases the closing part for pivoting about one of its two pivot axes, but exerts a force that pivots the closing part into the first open position and second open position, respectively, on the closing part. For this purpose, in one possible embodiment, the second end of the actuating arm is guided relative to the closing part via a slot guide (= sliding guide). Preferably, in this case, the slot (= the gate opening) is formed in the closing part and is penetrated by the actuating arm in the region of its second end.
When the actuating arm is adjusted from its initial position to its first end position, the closing part is pivoted to its first open position. When the actuating arm is adjusted from its initial position to the second end position, the closing part is pivoted to its second open position. In the initial position of the actuating arm pivoting of the closing member is blocked about both pivot axes and it is held both the first ends of the bracket and the closing part and the second ends of the bracket and the closing part of the actuating arm in mutual engagement and the snap hook is in its closed Status.
The actuating arm is adjustable from its initial position either in the direction of the first end position or in the direction of the second end position against the restoring force of at least one resilient element. Without the action of external forces of the actuating arm is held by at least one resilient element in its initial position.
The actuating arm is advantageously connected in the region of its first end with the insertion opening opposite back portion of the bracket and connected in the region of its second end with the closing part, wherein he divided the enclosed in the closed state of the snap hook from the bracket and closing part interior into two ge separated subspaces Opening of the first subspace takes place here by pivoting the closing part in its first end position, an opening of the second subspace is carried out by pivoting the closing part in its second open position. The subspaces are thus alternatively accessible by pivoting the closing part in its first open position and by pivoting the closing part in its second open position alternatively, for example for hanging a loop or hanging in an anchored rope.
It is conceivable and possible to provide a locking device by which the pivoting of the closing part about one of its pivot axes can be blocked. If an object, for example, a loop is mounted in the associated subspace of the snap hook and the pivoting of the closure member is blocked about this pivot axis with the locking device, the snap hook is secured to the hinged object, but the second subspace can still by pivoting the closing part to the other pivot axis are opened in order to hook the snap hook into different objects, for example different sections of an anchored rope. Also separate locking devices for the pivoting about the two pivot axes could be provided.

A first embodiment of a snap hook according to the invention is shown partially schematically in FIGS. 1 to 7. The snap hook comprises a substantially C-shaped bracket 1, which has an insertion opening 2. The insertion opening 2 is located between the first and the second end 3, 4 of the bracket 1. A back portion 5 of the bracket 1 is opposite to the insertion opening 2. The back portion 5 is connected to the first end 3 of the bracket 1 via a bent extending first bracket portion 6 and the second end 4 of the bracket 1 is connected to the back portion 5 via a second curved bracket section 7 extending. The first and second bracket sections 6, 7 are continuously bent in the exemplary embodiment except for an end section adjoining the respective end. It could, for example, also be present in one of the bracket sections 6, 7 or in the two bracket sections 6, 7 between two curved sections extending straight portion.
The closing part 8 has first and second ends 9, 10 and extends in the embodiment in a (straight) longitudinal direction, as is preferred. This longitudinal direction is parallel to the back section 5. An angular alignment with the back section 5 is possible. Such asymmetric carabiners are used for example as a via ferrata carabiner.
In the closed state of the snap hook, in which the closing part 8 is in its closed position, the first end 9 of the closing part 8 is in engagement with the first end 3 of the bracket 1 and the second end 10 of the closing part 8 is in contact with the second end 4 Strap 1 engaged. In the closed position of the closing part 8, the stirrup is surrounded by the stirrup. 4 · 4 · 4 · 4 · 4 4 4 4 4 4 4 4 f I 14 4 4 44 4 44 1444 4 I 4 · * 6 1 and the closing part 8 together an inner space 11 of the snap hook over the entire circumference of the inner space 11, that is in the manner of a closed ring.
The bracket 1, the closing part 8 and the inner space 11, which may also be referred to as a carabiner opening, lie in a common plane (= plane or median plane of the carabiner hook).
The first end 9 of the closing part 8 and the first end 3 of the bracket 1 are engaged by a bolt 12 fixed to the bracket 1 in a direction away from the interior 11 edge of the closing part 8 open slot 13 in the region of the first end of the 9 Closing part 8 is formed in this, is added. The bolt 12 extends between two side walls 14,15 of the bracket 1, which are released by a recess in the end portion of the bracket 1. The end 9 of the closing part 8 is located between these side cheeks 14, 15th
In the same way, the second ends 4, 10 of the bracket 1 and closing part 8 are in mutual engagement. The bolt 12 ', which extends between the side cheeks 14', 15 ', is received in the slot 13', which is formed in the region of the second end 10 of the closing part 8 and is in turn directed away from the interior 11 edge of the closing part 8. The end 10 of the closing part 8 lies between the side cheeks 14 ', 15'.
The bolt 12, 12 'could also protrude on both sides via a middle web arranged at the respective end of the bow 1 or could protrude such bolt parts on both sides from a central web. At the respective end of the closing part 8, the slots 13, 13 'could then be arranged on side cheeks, which overlap the center web on both sides.
The reverse arrangement is conceivable and possible, in which the bolts 12, 12 'are fixed in the end regions of the closing part 8 on the closing part 8 and the slots 13, 13' are arranged in the end regions of the bow 1. It could in this case again be formed by a recess at the respective end 3, 4 of the bracket 1 or at the respective end 9, 10 of the closing part 8 side walls, between which the end portion of the other of these two parts 1, 8 protrudes. If the slots 13, 13 'were arranged in the end sections of the bracket 1, they would be open towards the interior 11. · · »N · t · v« ·· »« ft ft ft · tit «4« ·· # ···· »* 44 * 7
To open the snap hook 1, starting from its closed state shown in FIG. 1, the closing part 8 either engages around the pivot axis 16 formed by the mutually engaging first ends 3, 9 of the bracket 1 and closing part 8 or in one of them pivoting shaft 17 formed formed stationary second ends 4, 10 of the bracket 1 and closing part 8. Fig. 2 shows the maximum pivoting of the closing part 8 about the pivot axis 16, in which the closing part 8 is in its first open position, Fig. 4 shows the maximum pivoting about the pivot axis 17, in which the closing part 8 is in its second open position , When pivoting the closing part 8 about the pivot axis 16, the second ends 4, 10 of the bracket 1 and closing part 8 are disengaged and the second end 10 of the closing part 8 moves into the region of the interior 11. When pivoting about the pivot axis 17, the first ends 3, 9 of the bracket 1 and closing part 8 is disengaged and the first end 9 of the closing part 8 moves into the region of the interior 11.
The pivot axes 16,17 are perpendicular to the plane in which the bracket 1, the closing 'part 8 and the interior 11 are (= main plane of the snap hook).
In order to keep the first ends 3, 9 of the bracket 1 and closing part 8 and the second ends 4, 10 of the bracket 1 and closing part 8 in the closed position of the closing part 8 in mutual engagement, an actuating arm 18 is provided. The actuating arm 18 is connected via its first end to the back portion 5 of the bracket 1 and via its second end to the closing part 8. In the starting position of the actuating arm 18, in which he holds the closing part 8 in its closed position, the second end of the actuating arm 18 in the region between the two pivot axes 16, 17 of the closing part 8 is connected thereto.
In the exemplary embodiment, the actuating arm 18 is pivotally mounted with its first end on the back portion 5 of the bracket 1. The connection of the actuating arm 18 with the closing part 8 takes place in the embodiment via a slot guide, which can also be referred to as a sliding guide, wherein the second end of the actuating arm 18 passes through a formed in the closing part 8 slot 19. The slot 19 has a circular arc-shaped course, with the pivot axis 20 of the actuating arm 18 as the center.
The pivot axis 20 of the actuating arm 18 is perpendicular to the common plane of the bracket 1, the closing part 8 and the inner space 11 and parallel to the pivot axes 16,17.
The actuating arm 18 penetrates in the region between its one end connected to the back portion 5, on the other hand with the closing part 8 ends the interior 11 and subdivided into subspaces 11 a, 11 b. In the first open position of the closing part 8, an article to be hooked into the snap hook can be introduced through the insertion opening 2 of the bow 1 into the subspace 11a (FIG. 2), in the second open position of the closing part 8 into the subspace 11b (FIG. 4).
The actuating arm 18 is shown in Fig. 1 in its initial position. In this, the actuating arm 18 is held against the restoring force of spring elements 21, 22. The spring elements 21, 22 may be formed for example by held in the slot 19 coil springs, which are supported between the edge located at the respective longitudinal end of the slot 19 and the actuating arm 18.
In the first open position of the closing part 8 shown in FIG. 2, the actuating arm 18 is in its first end position, in the second open position of the closing part 8 shown in FIG. 4 the actuating arm 18 is in its second end position.
In the embodiment in which the actuating arm 18 is pivotally mounted about the pivot axis 20, the adjustment of the actuating arm 18 from its initial position to one of its end positions by pivoting about the pivot axis 20. The pivoting direction is in this case opposite to the pivot direction in the pivoting in the first end position in the adjustment in the second Endsteliung.
In the illustrated embodiment of a symmetrical carabiner, the starting position of the actuating arm 18 is preferably located centrally between the two end positions.
In order to block the closing part 8 in its closed position, the actuating arm 18 cooperates with a contact surface 23 of the actuating arm 18 directed towards the inner space 11. This is formed in the embodiment of the edge of the slot 19. At this contact surface 23, the closing part 8 is supported on the actuating arm 18 against pivoting about one of its pivot axes 16, 17 and against displacement in the direction of the back section 5. The surface normal on the abutment surface 23 is directed to the location at which the one on the actuating arm 18th acting pressure force on the bracket 1 is derived, so in this embodiment, the pivot axis 20 of the actuating arm 18th
If the actuating arm 18 is adjusted from its central position in the direction of one of the two end positions, the blocking of the closing part 8 remains in its closed position in a first portion of the adjustment, which is conveniently at least 30% of the total adjustment in the respective adjustment, still exist ,
When the actuating arm 18 reaches the end of the adjustment path in the elongated hole guide formed by the elongated hole 19 during the adjustment in the direction of one of its settings, the closing part 8 about the respective pivot axis 16, 17 from the further adjustment of the actuating arm 18 in the direction of its respective end position Actuating arm 18 pivots, ie in the adjustment of the actuating arm 18 in the direction of its first end position to the formed by the engaged first ends 3, 9 of the bracket 1 and closing part 8 pivot axis 16 and in the adjustment of the actuating arm 18 in the direction of its second end position in the illustrated embodiment, the end of the adjustment is achieved in the slot 19 when the respective, formed by a coil spring spring element 21, 22 goes to the stop. At the end of the adjustment, which is in engagement with the closing part 8 second end of the actuating arm 18 has pivoted in this embodiment, at least up to the vicinity of the connecting line between the respective pivot axis 16, 17 of the closing part 8 and the pivot axis 20 of the actuating arm 18 (in the "Proximity" in this context means that at least 90% of the swivel angle has been traveled to reach this connecting line). Upon further adjustment of the actuating arm 18 in the direction of its respective end position, the pivoting of the closing part 8 takes place in the direction of its respective open position by the pulling force exerted by the actuating arm 18 on the closing part 8.
When the actuating arm 18 is thus adjusted by the user, starting from its initial position in one of its end positions, the closing part 8 is pivoted by the actuating arm 18 in one of its two open positions, whereby the carabiner is opened to one of the two subspaces 11a, 11b. 4 · «« 4 · ««
Fig. 5 illustrates the forces occurring when a force acts in the closed state of the snap hook on the closing part 8 in a region which is laterally adjacent to the abutment of the actuating arm 18 on the contact surface 23 of the closing part 8, in the sense of an indentation of the closing part 8 acts in the interior 11. The opposing forces are applied by the abutment of the actuating arm 18 on the contact surface 23 and by the engagement of the opposite end 9 of the closing part 8 in the cooperating end 3 of the bracket 1. 10
Fig. 6 illustrates how the respective active pivot axis 16, 17 opposite end of the closing part 8, here the first end 9, at the beginning of the pivoting out of engagement with the corresponding end 3 of the bracket 1 can pass. So that the first ends 3, 9 and the second ends 4, 10 are disengaged, the bolt 12, 12 'moves out of the slot 13, 13' in which it is received to form the respective pivot axis 16, 17.
Fig. 7 shows that, as soon as a certain angle of pivoting of the closing part 8 about one of the pivot axes, for example as shown the pivot axis 16 is achieved, the corresponding end 9 of the closing part 8, of which in cooperation with the associated end 3 of the bracket 1 this pivot axis 16 is formed, can no longer get out of engagement with the associated end 3 of the bracket 1. This angle is conveniently in the range between 5 ° and 25 °.
Due to the subdivision of the interior 11 into the two subspaces 11a, 11b, a transverse position of the carabiner between two hinged objects in the carabiner between which a tensile force is transmitted via the snap hook, can be prevented. The transferable in the transverse direction of the snap hook forces are usually less than the longitudinally transmissible forces (when the hinged objects are in the region of the bracket sections 6 and 7).
A slightly modified embodiment is shown in FIG. Here, the spring elements 21, 22 are not disposed within the slot 19 but are each connected at one end to the back portion 5 and at the other end to the actuating arm 18 at a distance from the pivot axis 20. The end of the adjustment of the actuating arm 18 in the slot 19 is here achieved in the two adjustment directions, respectively, when the actuating arm 18 starts at the respective end of the slot 19. During the further adjustment of the actuating arm 18 in this adjustment direction, the closing part 8 is pivoted by the actuating arm 18 in the direction of the respective open position of the closing part 8. Incidentally, this embodiment corresponds to the embodiment described above.
The exemplary embodiment illustrated in FIG. 9 corresponds to the exemplary embodiments described above, with the following differences:
The actuating arm 18 is resiliently bendable in this case. In the embodiment shown, this is achieved by a helical spring 24 wound on a block. This resilient design of the actuating arm 18 forms the resilient element, which exerts a restoring force against an adjustment of the actuating arm from its initial position. The adjustment of the actuating arm 18 in the direction of one of its two end positions takes place here by bending the actuating arm 18 in the corresponding direction {within the main plane of the snap hook). The end position of the displaceability of the actuating arm 18 in the slot 19 in one of the adjustment directions of the actuating arm 18 is reached when the actuating arm 18 starts at each end of the slot 19. As a result, the actuating arm 18 pivots the closing part 8 in its further adjustment in the direction of one of its end positions about the corresponding pivot axis 16, 17.
In the closed position of the closing part 8, the actuating arm 18 in turn supports the closing part 8 against being pushed in (sliding and / or pivoting) inwards.
The actuating arm 18 comprises in this embodiment, the coil spring 24 and attached to the coil spring 24 head 25, which has a slot 19 passing through the pin.
Elastic bendable actuating arms 18, which in the closed position of the closing part 8 can support this inwardly against a deflection, could also be formed in another way.
A further embodiment of the invention is shown in FIGS. 10 and 11. In this embodiment, the actuating arm 18 is not pivotably but slidably mounted on the back portion 5 of the bracket 1. For this purpose, the actuating arm 18 has, for example, as shown, a sleeve which is displaceably arranged on the back section 5. On the sleeve 26, the arm part 27 is attached. The remote from the back portion 5 end of the arm member 27 is connected to the closing part 8, for example, as shown via a slot guide. The slot 19 is arranged in the embodiment shown in the closing part 8 and the arm part 27 engages in this slot 19 a.
The actuating arm 18 is held by spring elements 21, 22 in the starting position. In this, the actuating arm 18 keeps the first and second ends 9, 10 of the closing part 8 with the first and second ends 3, 4 of the bracket 1 in turn engaged by the contact surface 23 of the closing part 8 at the remote from the back portion 5 end of the actuating arm 18th supported. The spring elements 21, 22 are formed for example by arranged on the back portion 5 coil springs. For example, embodiments would be possible in which the spring elements 21, 22 are arranged within the back portion.
In the initial position of the actuating arm 18, the remote from the back portion 5 end of the actuating arm 18 is located in a central region of the elongated hole 19, in which this runs parallel to the back portion 5. At the middle portion of the slot 19 close on both sides end portions, in which the slot for each end away from the back portion 5. If the actuating arm 18 is shifted from its initial position into one of its two end positions, the end of the actuating arm 18 remote from the back section 5, after it has passed through the middle section of the slot 19, enters the corresponding end section of the oblong hole, wherein it is the closing part 8 pivoted about the corresponding pivot axis. In Fig. 11, the pivoting about the engaged by the first ends 3, 9 of the bracket 1 and closing part 8 formed pivot axis is shown. During the adjustment of the actuating arm 18 in the other end position, the closing part 8 pivots about the pivot axis 17 formed by the engaged second ends 4, 10 of the bracket 1 and closing part 8.
As long as the remote from the back portion 5 end of the actuating arm 18 is located in the central portion of the slot 19, the closing member 8 is locked against opening.
Incidentally, this embodiment corresponds to the embodiments described above. 13
In all the described embodiments, for example, the following modifications are possible without departing from the scope of the invention:
It could be provided a locking device (securing device) for the actuating arm 18, of which is locked in a blocking position of the actuating arm 18 in its initial position. Only by adjusting the locking device in its release position, an adjustment of the actuating arm 18 in the direction of one of its end positions is possible. Such cooperating with the actuating arm 18 locking devices can be realized in different ways, for example by locking lever, pawls or the like, the pivoting or displacement of the actuating arm 18 block. It could in this case be provided for each of the two operating directions of the actuating arm 18 a separate blocking element or acting in both directions of actuation blocking element.
The remote from the back portion 5 end of the actuating arm 18 may be connected to the closing part 8 via a slidably mounted on or in the closing part 8 part. This displaceably mounted part could be displaceably mounted on a (partially or in total) arcuate path, so that the end of the actuating arm 18 remote from the back section 5 is guided on a corresponding path, which may correspond, for example, to the path illustrated in the respective embodiment of the figures. The remote from the back portion 5 end of the actuating arm 18 may be pivotally connected to this slidably guided part.
The formation of a slot guide could also be done in this way that at the remote from the back portion 5 end of the actuating arm 18, an arm portion with an enlarged extent in the direction of the closing part 8 is present, which has a slot into which engages a connected to the closing part 8 pin , In the embodiments shown in FIGS. 1 to 9, the slot could have the same shape as the illustrated slot 19 of the closing part 8. In the exemplary embodiment of FIGS. 10 and 11, the end sections of this oblong hole adjacent to the central section lying parallel to the back section 5 could approach the back section 5. 14
The invention is not limited to a symmetrical design of the bracket 1 according to the embodiments, but can also be used in asymmetric snap hooks. In these, the back portion 5 is aligned at an angle to the longitudinal extent of the closing * part 8. Such asymmetrical snap hooks, e.g. used as via ferrata carabiner, for example, from the above-mentioned prior art according to EP 1,229,258 A2.
The mutually engaging first ends 3, 4 and second ends 5,10 of the bracket 1 and closing part 8 could also have a different shape for the formation of pivot axes 16, 17, for example, could each be arranged at one end of a condyle, in engages a socket in the other of the two ends.
