Description

[0001] The invention relates to a safety device for a kite according to the preamble of claim 1.

[0002] Such a safety device typically has a chicken loop that can be connected to a trapeze hook on a harness and opened in an emergency using a release mechanism. The safety device is usually connected directly or via a common tow line to the two front lines, while the kite's steering lines (back lines) are attached to the ends of a bar that is radially traversed in the center by the tow line or the front lines and / or a safety line. The kite is also typically connected to the surfer via a safety leash, so that when the bar is released and the chicken loop opens, the kite descends without pressure and remains connected to the surfer via the safety leash.

[0003] Such a safety device is disclosed, for example, in US 6,988,694 B2 and US 6,691,954 B1. In these solutions, an eyelet or ring is formed at the end of the chicken loop, which can be hooked into a pivotally mounted pin of the safety device. To close the device, this pin, with the loop attached, can be placed upwards, i.e., away from the surfer, against the common tow line and secured there by means of a grip sleeve that is slid over the pin from above. This grip sleeve also runs along the tow line. To release the chicken loop, this grip sleeve is pushed away from the surfer, releasing the pivotally mounted pin. Due to the pulling force of the kite on the chicken loop, the pin folds downwards towards the surfer, thus completing the engagement between the pin and the ring.the eyelet at the end section of the loop is lifted and the chicken loop detaches from the trapezoidal hook.

[0004] A disadvantage of this solution is that the pin swings downwards when opening, resulting in a so-called "pin impact" which can injure the kitesurfer or at least be perceived as unpleasant.

[0005] In German patent application DE 10 2009 029 987 B4, which originates from the applicant, a solution is shown in which a pivot lever for releasing the working engagement does not pivot downwards, but is mounted in such a way that it pivots sideways and / or upwards when the sleeve is actuated, thus reliably preventing pin impact. This solution, which is the inverse of the prior art described above, is considered a major advantage on the market.

[0006] A disadvantage of both systems is that, after triggering, reassembling the safety device requires moving the handle sleeve in its actuation direction, i.e., away from the chicken loop, so that the pin or pivot lever is moved into an open position and the end section of the chicken loop can be inserted. After releasing the handle sleeve, this end section is then locked securely. This "assembly" typically requires two hands, primarily because the handle sleeve must be moved into and held in the open position. While solutions exist where the handle sleeve remains in its open position during insertion, it still needs to be moved against spring force to achieve this open position.

[0007] EP 3 466 805 A1 describes a safety device in which insertion takes place without adjusting the handle sleeve / handle, so that assembly can be carried out without problems even under unfavorable conditions, for example in heavy seas or the like.

[0008] In all the solutions described above, a safety line penetrating the described safety device is connected in the area of ​​the chicken loop to a safety leash, the free end section of which is usually detachably attached to the trapezoidal belt.

[0009] When the safety device is triggered, i.e., when the handle is activated, the chicken loop opens, so that the kite is only connected to the surfer via the safety line and the associated safety leash. The bar and the attached back lines are released, so the kite typically no longer generates any pull. However, in unfavorable conditions, the kite may rotate despite the chicken loop being released, subjecting the surfer to considerable forces that are usually difficult to control. In such an emergency, the safety leash can be detached from the harness, thus breaking the connection to the kite, which then drifts away from the surfer due to wind pressure.

[0010] This safety leash, used only in emergencies, must be long enough so as not to hinder the surfer. However, this considerable length has the disadvantage that, under normal conditions (chicken loop closed), the safety leash dangles back and forth between the chicken loop and the harness, thus obstructing the surfer. Beginners often forget to attach the safety leash when launching from the beach, meaning that if the chicken loop is released, the kite can no longer be controlled. Releasing the safety leash, which is attached to the side or back of the harness strap, is also problematic in the emergency described.

[0011] European patent application EP 2 604 502 A1 discloses a safety device in which a chicken loop is coupled to a safety line and a tow line connected to front lines via two release mechanisms. The tow line can be released first via the first release mechanism, and then the safety line can be released via the second release mechanism. In the known design, the chicken loop remains attached to the trapeze webbing / trap hook. In this known safety device, the chicken loop is further connected to the trapeze webbing via a safety leash.

[0012] The two triggering mechanisms are mounted on a single base body of the chicken loop, with triggering occurring via oppositely actuated release elements. This design necessitates a very complex chicken loop construction. Furthermore, the triggering occurs in opposite directions, meaning that operation in an emergency is not intuitive but requires careful consideration. Another disadvantage is that the overall weight of the safety device is considerable due to the highly complex chicken loop construction.

[0013] In contrast, the invention is based on the objective of creating a safety device with improved ease of use and simple construction.

[0014] This problem is solved by a safety device with the features of claim 1.

[0015] Advantageous further developments of the invention are the subject of the dependent claims.

[0016] The safety device according to the invention is designed for a kite or the like and has a safety line that passes through a quick-release (QR) device. The quick-release device has a release mechanism that can be adjusted from a closed position to a released position by means of a handle, preferably a release cap. The safety device further has an integrated safety device for connecting to a trapeze hook, which is coupled to the QR device, wherein the coupling is at least partially released in the released position. The safety device has a base that can be connected to the trapeze hook and a holder for the safety line, which is detachably connected to the base by means of a safety mechanism.

[0017] The QR device is designed with two pivot levers (pins) mounted on a main body, which in the closed position are in locking engagement with a respective pull element / counterpart formed on the safety device, whereby the pivot levers are held in the closed position by the handle and pivot into the release position when the handle is actuated.

[0018] According to the concept according to the invention, the compact safety device is thus directly connected to the trapezoidal hook, wherein the safety line is attached to the bracket, which in turn is detachably connected to a base attached to the trapezoidal hook.

[0019] When the safety device is triggered, the base remains attached to the trapeze hook, while the bracket connected to the safety line is completely detached from the trapeze hook, allowing the kite to drift away.

[0020] This innovative concept eliminates the need for a separate safety leash that would otherwise hinder the surfer, significantly improving ease of use compared to the solutions described earlier. Another advantage is that before launching the kite, for example on the beach, only the safety device needs to be connected to the harness hook, virtually eliminating the possibility of incorrect attachment.

[0021] The QR device concept allows, similar to the state of the art described at the beginning, the QR device to be detached from the trapeze hook, so that the kite is then only connected to the trapeze strap via the safety line and the safety device.

[0022] According to a further development of the invention, a tubular guide for the safety line connected to a rotor head is rotatably mounted on the main body, with the two pivot levers preferably being arranged symmetrically on both sides of the guide.

[0023] In a simple embodiment, the traction element / counterpart on the safety device side is designed as a bracket, the end section of which, in the closed position, penetrates the main body of the QR device in the direction of the pivot lever.

[0024] In a preferred embodiment of the invention, the safety mechanism is actuated by means of a handle sleeve, so that when the handle sleeve is adjusted, the safety line is released.

[0025] The design of the safety device according to the invention is particularly compact if the grip sleeve and the handle are arranged coaxially to each other and are adjustable.

[0026] Functional reliability is optimal when the operation of the handle sleeve is blocked or made more difficult in the closed position of the handle.

[0027] The safety device bracket can be connected to the safety line on one side and to the base on the other via a toggle lever of the safety mechanism. The toggle lever is mounted in such a way that, in the handle sleeve's home position, it holds the bracket to the base and releases it when the handle sleeve is moved into a tilting position.

[0028] The adjustment of the handle and / or the grip sleeve is preferably carried out against a preload which is designed such that the handle / grip sleeve is preloaded in its basic position.

[0029] According to a further development of the invention, the handle and the grip sleeve are guided in such a way that their operation is away from the trapeze hook - this corresponds to the intuitive direction of movement according to which the kite should move away from the surfer in an emergency.

[0030] The safety device is particularly versatile when it features a modular design with a chicken-loop module. This module can be attached to the QR code when the safety device is removed. The existing bracket for the safety device, connected to the safety line, can still be used. This module allows for freestyle maneuvers where the surfer detaches the safety device from the harness hook and reattaches it after the maneuver. This is achieved simply by replacing the safety device with the chicken-loop module, ensuring highly adaptable use of the safety system.

[0031] In one embodiment of the invention, the chicken-loop module has an end section that is held by one of the two pivot levers of the QR device, the pivoting of this pivot lever being blocked. The other end section of the chicken-loop module is detachably connected to the other pivot lever in a manner known per se.

[0032] The triggering is particularly precise if a guide is formed on the main body of the QR device along which the traction element / counterpart or the end section of the chicken-loop module slides when released.

[0033] The safety device is connected to the trapezoidal hook, for example, via a carabiner or other connecting device.

[0034] Advantageous embodiments of the invention are explained in more detail below with reference to schematic drawings. These show: Figures 1 and 2a front view and a side view of a safety device according to the invention; Figure 3 the safety device according to the Figures 1 and 2 in a representation without trigger cap and grip sleeve; Figure 4 a sectional view of the safety device according to the Figures 1 to 3 ; Figure 5 another sectional view showing the safety device in a release position of a QR device; Figure 6 a bottom view of the QR device according to the Figures 4 and 5 ; Figure 7 a sectional view of a safety device of the safety device according to the Figures 1 to 6 ; Figure 8 the safety device according to Figure 7 without handle sleeve; Figure 9 a top view of the safety device according to the Figures 7 and 8 ; Figure 10 one Figure 7 corresponding representation of the safety device in the triggered state; Figure 11 a chicken loop module attached to the QR device; Figure 12the order according to Figure 11 without trigger cap; Figure 13 a sectional view of the safety device according to the Figures 11 and 12 with attached chicken loop module and Figure 14 a Figure 13 corresponding cut with the chicken loop module open.

[0035] In the Figures 1 and 2 Figure 1 shows a safety device 1 according to the invention – also called a safety device. This device serves, in principle, to connect a kite to a trapeze hook of a trapeze harness via its front lines. The safety device 1 according to the invention essentially has two assemblies: a QR (quick release) device 2 and a safety device 4. As shown in the view, a [missing element] protrudes from the QR device 2. Figures 1 and 2Upwards, a rotor head 6 is formed at the end section of a tubular guide 8, which is supported in the QR device 2 via a rotor bearing, thus enabling, for example, the unwinding of the front lines of a kite. In the illustration according to Figure 1 Reference numeral 10 designates a safety line, while reference numeral 12 designates a front line which is preferably eccentrically fixed to the QR device 2, while the safety line 10 passes through the tubular guide 8 and, as will be explained in more detail below, is fixed in the area of ​​the safety device 4.

[0036] At the one in the Figures 1 and 2 The lower end section of the safety device 4 shows a connecting element, for example a carabiner 14, via which the safety device 1 is attached to a trapezoidal hook or a trapezoidal line of a trapezoidal harness.

[0037] The QR device 2 has a release cap 16, which, by adjusting this cap, can be separated from the safety device 4, so that the kite is only connected to the harness via the safety line 10. Similarly, the safety device 4 has a handle 18, which, when the QR device 2 is released, can be operated to also release the safety line 10 from the harness, so that the kite is no longer connected to the surfer.

[0038] As further evidenced by the Figures 1 and 2 As can be seen, the safety device 1 is shown in the front view according to Figure 1 slightly wider than in the Figure 2The illustrated side view ensures ergonomically advantageous operation of the release cap 16 and the grip sleeve 18. The release cap 16 has a circumferential grip groove 20, which facilitates gripping and ensures that sufficient release force is applied. The grip sleeve 18 is operated considerably less frequently than the release cap 16 and has a [missing information - likely a specific feature or characteristic] in the adjustment direction (upwards in the [missing information - likely a specific location or feature]. Figures 1 and 2 , i.e. away from the surfer) a grip collar 22, which protrudes slightly in the radial direction, so that a sufficient adjusting force can also be transmitted.

[0039] In the three-dimensional representation according to Figure 3The handle sleeve 18 and the release cap 16 are not shown, so that the "internal workings" of the safety device 1 become visible. In this illustration, the rotor head 6 with the associated tubular guide 8, which is rotatably mounted on a main body 24, can be clearly seen. The rotatable mounting is effected by a rotor bearing 26, which is arranged on the main body 24 of the QR device 2. As explained in more detail below, two pivot levers 28, 30 are mounted on both sides of the guide 8, the basic structure of which is explained in the aforementioned EP 3 466 805 A1 of the applicant, so that only features important for understanding are described here, and reference is made to the disclosure of this publication for further details. Accordingly, the two pivot levers 28, 30 each have two drive legs 32a, 32b and 32b, respectively.34a, 34b, which in the illustrated closed position bear against stop surfaces of the release cap 16, so that they cannot pivot towards the guide 8. The distance between the drive legs 32a, 32b and 34a, 34b is chosen such that they have a larger clear width than the diameter of the guide 8, so that the drive legs 32a, 32b; 34a, 34b can pivot so that they come to lie on both sides of the guide 8 (approximately tangentially). The pivot bearing of the pivot levers 28, 30 is each achieved via a pivot axis 36, 38, which is inserted into brackets of the main body 24 and passes through the respective pivot lever 28, 30. Each pivot lever 28, 30 is secured with a retaining pin 40, 42 (the latter not visible in the figure). Figure 3 ) formed, which is approximately angled and in which in Figure 3In the depicted closing position, the safety device 4 is engaged by a lever (traction element) 44, 46. This connects the two approximately U-shaped levers 44, 46 tensilely to the QR device 2 and its main body 24, respectively.

[0040] These two brackets 44, 46 are attached to a base 48 of the safety device 4, which in turn is connected to the trapezoid via the carabiner 14. An approximately L-shaped rocker arm 54 is mounted on support legs 50, 52 of the base 48, rotating about a horizontal axis 56 (see dashed line in Figure 1). Figure 3 ) is pivotable. The rocker arm 54 has a retaining leg 58 which is in the Figure 3In the illustrated closed position (handle sleeve 18 not actuated), a bracket 60 connected to the safety line 10 engages behind it, so that it is secured in the pulling direction of the safety line 10. In the illustrated embodiment, the bracket 60 is made of round material in a basket-like shape, wherein the area in effective engagement with the retaining leg 58 is approximately U- or V-shaped and extends upwards (view to Figure 3 ) transitions into a retaining ring 62, which is connected to the safety line 10. In the illustrated embodiment, this connection is made via a stopper ball 64 (indicated by dashed lines), which is connected to the end of the safety line 10 and is held back by the retaining ring 62, the inner diameter of which is smaller than the diameter of the stopper ball 64.

[0041] The rocker arm 54 also has a return leg 66 which, when the handle sleeve 18 is not adjusted, rests against its inner circumferential wall, so that the rocker arm 54 is in its Figure 3 The basic position shown is maintained.

[0042] Both the two pivot levers 28, 30 and the rocker lever 54 can be pre-tensioned in the direction of the respective release / unlock position via elastic pre-tensioning elements, so that the respective triggering takes place very quickly and without delay.

[0043] How Figure 3 Furthermore, the two drive legs 32a, 32b are removable and have a shorter length than the drive legs 34a, 34b, so that no collision is possible when the pivot levers 28, 30 are pivoted in the direction of the guide 8.

[0044] The structure of safety device 1 will be explained again using the following examples: Figure 4 explained, which shows a longitudinal section through the safety device 1 according to the Figures 1 and 2This cross-sectional view shows the rotor head 6 with the tubular guide 8, which is mounted in the main body 24 of the QR device 2 via the rotor bearing 26. As explained, the drive arms 32a, 34a of the pivot levers 28, 30, visible in this longitudinal section, rest against stops 68, 70 of the release cap 16, thus preventing the pivot levers 28, 30 from pivoting about their respective pivot axes 36, 38. The two retaining pins 40, 42 are angled relative to the drive arms 32a, 32b and 34a, 34b, respectively, and extend beyond the two end sections 72, 74 of the U-shaped brackets 44, 46. Figure 4 Removable, these end sections 72, 74, which run perpendicular to the plane of the drawing, dip section by section into retaining recesses of the retaining pins 40, 42, as shown in the illustration according to Figure 4Only the recess of the retaining pin 42 is marked with reference numeral 76. The end sections 72 and 74 are each supported on inclined surfaces 78 and 80 of the main body 24. These surfaces are inclined so that they slope outwards towards the release cap 16.

[0045] As explained above, the safety line 10 is guided through the guide 8 and connected to the stopper ball 64, which extends in the direction of pull (upwards). Figure 5 ) is held by the retaining ring 62 of the bracket 60. The approximately V-shaped bracket 60 engages the retaining arm 58 of the rocker arm 54, which in the illustrated basic position is also supported on the inside of the handle sleeve 18. As explained, this ensures that the safety line 10 is tensilely connected to the safety device 4 in the direction of pull of the kite.

[0046] The two brackets 44, 46 are inserted into the base 48 of the safety device 4.

[0047] The carabiner 14 or other connecting means is also attached to this, by means of which the safety device 1 is fixed to the trapeze, in particular the trapeze hook.

[0048] As explained, safety device 1 is in Figure 5 shown in the closed position, in which the pivot levers 28, 30 and the rocker lever 54 are each pre-tensioned to their engagement position and the release cap 16 and the handle sleeve 18 are pre-tensioned to their home position.

[0049] Figure 5The safety device 1 is shown in a release position, which is set by actuating the release cap 16 of the QR device 2. The release cap 16 is thereby moved against its preload, which is generated, for example, by a preload spring, along the outer circumference of the tubular guide 8 in the direction of the rotor head 6, so that the two pivoting levers 28, 30 can pivot about their respective pivot axes 36, 38. In doing so, the two retaining pins 40, 42 pivot outwards, so that the end sections 72, 74 of the brackets 44, 46 slide off the inclined surfaces 78, 80 of the main body 24 and into the Figure 5The relative position shown is released from the main body 24, so that the QR device 2 is separated from the safety device 4, although the safety line 10 is still held on the retaining ring 62 of the bracket 60. During this release, the distance between the two brackets 44, 46 widens slightly as they slide on the inclined surfaces 78, 80, allowing them to detach from the main body 24. The brackets 44, 46 are pulled out through corresponding openings in the main body 24. The bracket 60 is fixed in position in the safety device 4 by the rocker arm 54. The two drive arms 32a, 32b and 34a, 34b pivot towards the guide 8, so that the guide is positioned between the drive arms 32a, 32b and 34a, 34b, respectively.

[0050] After this release process, the kite is then only connected to the trapeze strap via the Safetyline 10, so that the kite sinks without pressure.

[0051] Figure 6 Figure 1 shows a bottom view of the QR device 2, although the release cap 16 is not shown. The main body 24 is visible, in which the tubular guide 8 is mounted centrally above the rotor bearing 26. The two retaining pins 40, 42 are aligned with respect to openings 82, 84 in the main body 24, which are defined by the end sections 72, 74 of the brackets 44, 46 (not shown in Figure 2). Figure 6 ) are intersected. In the closed position, these are partially engaged by the recesses 76, 84 of the retaining pins 40, 42. In this illustration, the inclined surfaces 78, 80 for guiding the end sections 72, 74 are also visible.

[0052] In Figure 7A longitudinal section of the safety device 4 in the closed / home position is shown. The handle sleeve 18 rests on the base 48 under spring tension, and the rocker arm 54 rests with its return leg 66 against a stop surface 86 of the handle sleeve 18, preventing the rocker arm 54 from pivoting about the tilting axis 56. Accordingly, the retaining leg 58 overextends the apex of the bracket 60, thus fixing it in position in the direction of the kite's pull. The approximately V-shaped legs of the bracket 60 transition into the retaining ring 62, on which the safety line 10 (not shown) is supported via the stopper ball 64 (also not shown). As explained, the rocker arm 54 is mounted on the support legs 50, 52 via the tilting axis 56. In the sectional view according to... Figure 7 The bracket 44 with the end section 72 can also be seen, which in the closed position is engaged by the retaining pin 40, 42.

[0053] Figure 8Figure 1 shows a three-dimensional representation of the safety device 4 without the handle sleeve 18. Visible are the two brackets 44, 46 with their end sections 72, 74, which are anchored in the base 48. Protruding from this base are the two support legs 50, 52, on which the rocker arm 54, with its retaining leg 58 and return leg 66, is pivotally mounted. This view also clearly shows that the rocker arm has two lateral guide bushings 88, 90, which are penetrated by the tilting axis 56 and extend between the two support legs 50, 52, so that the rocker arm 54 is reliably positioned between them.

[0054] As explained, the retaining leg 58 overlaps the apex of the bracket 60, whose retaining ring 62 supports the stopper ball 64 in the direction of pull.

[0055] Figure 9 shows a top view of the safety device 4 according to Figure 8 .

[0056] Accordingly, the grip sleeve 18 engages the bracket 60 with the retaining ring 62, the bracket 60 being held in the direction of pull by the retaining leg 58 of the rocker arm 54. In this illustration, the two guide bushings (bearing arms) 88, 90 of the rocker arm 54 are also clearly visible. The two brackets (44, 46?) protrude upwards from the grip sleeve 18 with their end sections 72, 74.

[0057] In Figure 10 The safety device 4 is shown in a release position. This is achieved by adjusting the handle sleeve 18 upwards (towards the kite). However, this adjustment is preferably only possible if the QR device 2 has been triggered.

[0058] As in Figure 10As shown, after adjusting the handle sleeve 18 against its preload, the rocker arm 54 can pivot about its tilting axis 56, so that the retaining leg 58 releases the bracket 60 and thus the safety line 10 is released from the base 48 and thus also from the trapeze and the kite is freed, so that the surfer is no longer endangered.

[0059] The concept described above essentially creates a two-stage safety device 1, where the QR device 2 has roughly the same function as a conventional quick release (safety). The function of the cumbersome and awkwardly handled safety leash is taken over in this concept by the safety device 4, which is attached directly to the trapeze and can be released from the trapeze via the safety mechanism after the QR device 2 has been triggered.

[0060] As explained at the outset, under certain conditions it is desirable to detach the safety device 1 from the trapeze, in particular from the trapeze hook, and then reattach it. Such maneuvers are difficult to perform with the described safety device 1. According to the invention, a chicken-loop module 92 is assigned to the safety device 1, which can be attached to the QR device 2 in place of the safety device 4. This embodiment is described in Figure 11 The chicken-loop module 92 is attached to the previously described QR device 2, whereby a chicken-loop 94 of the chicken-loop module 92 can be opened by actuating the release cap 16 in order to detach the chicken-loop 94 from the trapezoidal hook. A chicken-dick is shown in the illustration according to Figure 11not shown and in principle not required, since the Chicken Loop module 92 is usually only used when permanent fixation to the trapezoidal hook is not desired.

[0061] As in Figure 11 As shown, the bracket 60 remains connected to the safety line 10, with a safety leash (not shown) attached to this ring-shaped bracket 60 in the conventional manner, its free end section then being attached to the trapeze. Such a solution does not differ in its basic function from conventional quick-release devices.

[0062] In Figure 12The chicken-loop module 92 connected to the QR device 2 is shown without the release cap 16. Accordingly, approximately U-shaped retaining brackets 96, 98 are provided at the end sections of the chicken-loop 94, which are fixed in position by the pivot levers 28, 30. The geometry of the retaining brackets 96, 98 essentially corresponds to the geometry of the brackets 44, 46 of the safety device 4, so reference is made to the relevant descriptions regarding the effective engagement.

[0063] Since the chicken loop 94 is typically intended to open only on one side, the pivot lever 30 of the chicken loop module 92 is prevented from pivoting, so that it is fixed in the engagement position with the retaining bracket 96. In the illustrated embodiment, this fixation is achieved by a locking pin 100, which is inserted into corresponding receptacles of the two drive arms 34a, 34b, so that the drive arms 34a, 34b, and thus the entire pivot lever 30, cannot pivot, as the locking pin 100 comes into contact with the outer circumference of the guide 8. When the release cap 16 is adjusted, the pivot lever 30 therefore remains in its engaged position. Figure 12 in the relative position shown, while the other pivot lever 28 pivots out in the manner described above and releases the retaining bracket 98 of the chicken loop 94, so that it can detach from the trapezoidal hook.

[0064] Figure 13 shows a longitudinal section through the arrangement according to Figure 11 , in which the QR device 2 is in its closed position. Accordingly, the release cap 16 rests on the main body 24, so that the two pivot levers 28, 30 with their retaining pins 40, 42 press the retaining brackets 96, 98 against the inclined surfaces 78, 80 and the chicken loop 94 cannot release. As explained, the pivot lever 30 is secured against pivoting by the locking bolt 100.

[0065] This is readily apparent from Figure 14 , which the order according to Figure 13 in the release position. This release position is set, as explained, by adjusting the release cap 16 towards the rotor head 6. This movement of the release cap 16 moves the stop 68 associated with the pivot lever 28 (not visible in Figure 14) is no longer effective, so that the pivot lever 28 with its drive arms 32a, 32b can pivot towards the guide 8, so that the retaining pin 40 releases the retaining bracket 96. The other retaining bracket 98 remains in contact with the inclined surface 80, since the pivot lever 30 is prevented from pivoting. In the release position, the retaining bracket 96 then slides along the inclined surface 78 as described above, so that the chicken loop 94 opens.

[0066] To attach the safety device 4, the locking bolt 100 is removed from the pivot lever 30 so that, with the release cap 16 adjusted, the pivot lever 30 also releases its associated retaining bracket 98, allowing the chicken loop 94 or the chicken loop module 92 to be easily removed. The safety device 4 is then inserted as described above, so that the two brackets 44, 46 engage with the QR device 2.

[0067] The safety device according to the invention is characterized by high functional reliability in compact dimensions.
