EP3611091B1 - Trapeze closure and trapeze strap - Google Patents

Description

The invention relates to a harness buckle for a harness for kitesurfing, windsurfing or sailing and a harness belt with such a harness buckle.

Such harness belts can be designed as a waist harness or as a seat harness and usually have a harness hook that is attached to a front bracket or a front panel. A hip belt with a padded back part is attached to this front panel and is provided with pads/reinforcements or the like in the area of the lumbar spine. Since, for example, when kite surfing, the forces introduced via the kite act relatively strongly in the vertical direction, it is particularly important for waist harnesses that they fit well. Accordingly, the trapeze must be applied relatively tightly to the body to prevent it from slipping. In order to simplify this application, trapezoids usually have a trapezoid fastener in which a snap-hook element is hooked into an eyelet, with adjustable straps between a hook plate or the front bracket and the back part making it possible to adapt to the waist circumference.

The problem here is that the carabiner has to be hooked into the eyelet with a relatively large amount of force in order to ensure that the trapeze fits exactly on the hip. The release of this lock is also particularly problematic, since in order to release the carabiner, a corresponding pretension must be applied in order to be able to unhook the carabiner.

In the DE 20 2004 006 143 U1 a solution is explained in which the snap hook is secured to the eyelet by a spring clip and can be brought out of its locking position into a release position by means of a handle. Specifically, this handle can be designed as a pull strap, via which the surfer can apply a comparatively large amount of force to release it.

The problem with this variant, however, is that it is still difficult to hang the carabiner in the eyelet, since the hand has to be placed between the carabiner and the body in order to be able to apply the required pulling force.

Many surfers therefore loosen the straps to put them on, then attach the trapeze buckle and then tighten the straps again - this procedure is very cumbersome.

In the EP 2 834 309 A2 To overcome this disadvantage, the applicant describes a trapeze belt in which a locking piece of a trapeze lock that can be connected to a ring-shaped or eyelet-shaped retaining element is designed as a pivoted lever that is pivoted about a pivot axis. This pivoting lever has a suspension hook on a first end section and a locking hook at a distance therefrom, the pivot axis being formed at a distance from the suspension hook. When putting on the trapeze belt, the restraining element is first hooked into the hanging hook, this hanging process being very simple since the harness belt is loose. By pivoting the pivoting lever into its closed position, the locking hook comes into operative engagement with the retaining element, this pivoting shortening the effective length of the trapezoidal lock and thus the circumference of the harness strap, so that the trapezoidal strap sits tautly in the desired manner.

Practice has shown that such a harness is extremely easy to put on. A disadvantage of all the solutions described, however, is that the adjustment of the harness belt to the hip circumference of the respective user, which depends, among other things, on the physique and the clothing worn, is cumbersome, since the harness fastener described above is usually connected to the actual hip on both sides via two belt straps - Or seat harness - hereinafter referred to as the harness belt - is connected and the length adjustment of these straps is done via belt tensioners, which are very cumbersome to use and moreover are often accommodated in a pocket of the harness and are thus very difficult to access and operate.

In the US 6,293,215 B1 discloses a front panel with a harness hook, with snapped locking elements attached to the end portions of the hook plate, which interact with toothed straps, the end portion of which remote from the hook plate is fastened to the waist strap. The interlocking engagement can be released by pressing a release on the hook plate.

A similar solution is in the DE 201 00 469 U1 disclosed. Another example can be found at https://www.youtube.com/watch?v=LqSmDhGhBo8.

The disadvantage of these solutions is that they are relatively difficult to put on, since the straps have to be inserted into the locking mechanism each time.

In the pamphlet NL 102 95 15 C1 a trapeze lock is shown in which a long pivoting lever is articulated on the hook plate or a bar carrying the trapeze hook and can be brought into tightening engagement with an end fitting which is connected to the actual trapeze belt via belts or the like. This solution is problematic because, on the one hand, the pivoting lever requires a considerable installation space and pivoting range and, on the other hand, the hanging of the end fitting and the pivoting of the pivoting lever require a certain skill on the part of the user.

In contrast, the invention is based on the object of creating a trapeze belt with improved handling.

This object is achieved by a harness buckle with the features of patent claim 1 and a harness belt with the features of patent claim 11 .

Advantageous developments of the invention are the subject matter of the dependent claims.

The trapeze lock according to the invention has at least one end fitting which can be coupled to the actual trapeze belt by means of belts or other traction means. A locking piece of the trapezoidal lock can be brought into tightening engagement with a retaining element formed on a hook plate or the like, this locking piece being connected to the end fitting by means of a pivoted lever arrangement in such a way that the end fitting can be moved or adjusted in the tightening direction when the pivoted lever arrangement is actuated. According to the invention, the tensioning is thus carried out by adjusting the end fitting and not, as in conventional solutions, by tensioning devices on the hook plate. According to the invention, the closing piece has at least two approximately parallel, hook-shaped claws which can be brought into engagement with the retaining element in a non-positive and positive manner. This form-fitting engagement takes place in such a way that tilting of the claws in relation to the retaining element can be essentially prevented during clamping and also during use.

In one embodiment of the invention, these claws are made of metal or a fiber-reinforced plastic. These claws can be formed on a claw plate, so that the closing piece is formed by the claws and the claw plate.

According to the invention, the pivoting lever arrangement has a pivoting plate which is articulated on the closing piece by means of an articulation and which in turn is connected to the end fitting at a distance from the articulation via a pivot joint. The required tension can then be applied to the trapeze belt by actuating the swivel plate.

Actuation is particularly easy if the swivel plate extends beyond the swivel joint, so that a comparatively large lever arm is created in relation to the linkage.

In a preferred embodiment, the pivot plate is pivoted for clamping in a position towards the closing piece, so that the Claws are then essentially covered and are thus secured even better against twisting/loosening.

Functional reliability can be further improved if the swivel plate is locked in this swivel position.

The form-fitting engagement of the at least one hook-shaped claw can be achieved, for example, in that each of these dips into a pocket of the retaining element with a precise fit, at least in sections.

It is particularly preferred if the claw has a hook-shaped end section and an adjoining claw bar that dips into the pocket, so that the claw bar is supported in the pocket transversely to the pulling direction.

In one embodiment, the two claws are offset laterally, that is to say transversely to the claw web extension, and are formed on a claw plate. This development simplifies the positioning of the closing piece in relation to the retaining element.

In this way, an exact relative positioning of the closing piece with the two hook-shaped claws in relation to the retaining element is ensured even before the pivoting plate is pivoted.

A particularly compact solution is obtained when the retaining element and the pockets are integrated into the hook plate.

In a particularly simple embodiment, the retaining element is designed with bolts, each of which is arranged in a pocket. Alternatively, of course, the retaining element can also be formed by corresponding ribs/webs, which can be encompassed by the hook-shaped claws.

Instead of the two claws arranged approximately parallel, a single wide claw can also be used. The applicant reserves the right to make his own claim to this solution.

The harness according to the invention is designed with a harness buckle according to the invention.

The trapeze described below can be designed as a waist harness or seat harness and is suitable for kitesurfing, windsurfing or sailing. In the following explanations, a waist harness, referred to below as a harness, is described. This harness belt 1 has according to in figure 1 schematically illustrated top view of a hip belt 2 with a back part 4, which has, for example, a reinforcement to distribute the forces on the back area. The back part 4 is adapted or adaptable to the anatomy of the back and goes into two side parts 6, 8 over, which are designed to be much more elastic than the back part 4 and enclose the torso of the user laterally. As an extension of the side parts 6, 8, front flaps 10, 12 on the stomach side can be provided, which are connected by means of a Velcro fastener when the harness belt 1 is put on.

The two side parts 6, 8 are directly or indirectly connected to a front or hook plate 14, which stretches over the two front straps 10, 12 and on which a trapezoid hook 16 is attached. In the illustrated embodiment, the hook plate 14 is designed as a molded piece made of plastic that rests flat on the abdomen. In principle, however, the solution according to the invention can also be implemented with a conventional metal bar on which the trapeze hook 16 is arranged.

The exchangeable hook plate 14 is connected to the side parts 6, 8, for example, in a conventional manner via belt straps 18, 20, which are deflected with frictional engagement at end fittings 22, 24, so that the trapeze belt 1 can be preset by adjusting these belt straps 18, 20. the inside figure 1 left end fitting 24 is part of a trapezoidal closure 26, via which the end fitting 24 is connected to the webbing 20 with the adjacent end section of the hook plate 14. As explained below, this trapezoidal lock 26 is designed in such a way that it can initially be hooked into the hook plate 14 without pretension and then brought into a tensioned position in which the associated end fitting 24 can be moved/adjusted in the tensioning direction, i.e. towards the hook plate 14 .

figure 2 shows a front view of the in figure 1 left end portion of the hook plate 14. This has at its in figure 2 The end section shown has two pockets 28, 30, into which the trapezoidal closure 26 with two hook-shaped claws 32, 34, which will be explained in more detail below, dips and thereby encompasses retaining elements designed as bolts 35, for example. In the representation according to figure 2 only one of the bolts 35 is visible. These bolts 35 pass through the pockets 28, 30 transversely to the longitudinal extent of the pockets 28, 30. As will be explained in more detail below, the end fitting 24 is articulated on the trapezoid closure 26, and the straps are then looped through the end fitting. In figure 2 the trapezoidal closure 26 is shown in its closed position, in which the claws 32, 36 and the pockets receiving them 28, 30 is covered at least in sections by a swivel plate 36. In this tightening/closing position of the trapeze lock 26, the belt straps 18, 20 are subjected to the maximum tensile force, which ensures that the trapeze belt 1 fits perfectly.

figure 3 shows the arrangement according to figure 2 in the relaxed state. For this purpose, the pivoting plate 36 of the trapezoidal lock 26 is pivoted away from the hook plate 14 . As explained in more detail below, the end fitting 24 is articulated on the pivoting plate 36, so that the end fitting 24 is also moved in the relaxation direction accordingly - in other words, by opening the trapezoidal lock 26 in the figure 3 In the way shown, the clear width of the trapeze belt 1 is increased so that the trapeze lock 26 can be unhooked from the hook plate 14 . in the in figure 3 In the illustrated pivoting position of the pivoting plate 36, the two hook-shaped claws 32, 34 can be seen, which dip into the pockets 28, 30 with a precise fit and thereby engage around the bolts 35.

As mentioned, the claws 32, 34 can then be unhooked practically without the application of force due to the relaxed trapezoidal lock 26, so that the operative engagement with the bolts 35 is eliminated. The width B of the pockets 28, 30 corresponds approximately to the width of the claws 32, 34, so that these lie against the peripheral walls of the pockets 28, 30 and thus the two claws 32, 34 cannot tilt in relation to the hook plate 14. This is a problem, particularly in the case of trapezoidal closures with a single hook-shaped closing piece, which reduces the wearing comfort when there are high lateral loads. This disadvantage is eliminated by the solution according to the invention.

figure 4 shows the trapezoidal fastener 26 in an individual representation, with the trapezoidal fastener 26 being opened/relaxed. It can be seen in the representation according to figure 4 the two approximately parallel claws 32, 34, which in principle each consist of a hook-shaped end section 38, 40, which are connected via claw webs 42, 44 to a claw plate (see also figure 3 ) 46 are connected. On the claw plate 46 there are two joint straps 48, 50 (the latter is shown in figure 2 to see) perpendicularly upwards (view after figure 4 ) with respect to the pivot plate 36 is bent. at these Joint plates 48, 50 are then articulated via an articulation 52, the pivot plate 36. This has a pivot joint 54 at a distance from the linkage 52, via which the end fitting 24 is pivotably connected to the pivot plate 36. According to the illustration figure 4 It can be seen that when pivoting plate 36 is pivoted toward claws 32, 34, end fitting 24 is entrained toward claws 32, 34, so that the tension described above is applied to straps 18, 20. In order to improve the leverage, the swivel plate 36 is lengthened beyond the swivel joint 54 to form a handle 56 .

figure 5 shows a view of the trapezoidal closure 26 according to FIG figure 3 , In which the two claws 32, 34 are arranged in front. The two claws 32, 34 are connected via the two claw webs 42, 44 to the claw plate 46, on which the two articulated brackets 48, 50 angled by 90° are formed. In the illustrated embodiment, the two claws 32, 34 are not symmetrical when viewed in the direction of pull, but are arranged slightly laterally offset on the claw plate 46, so that the claw 34 or its claw web 44 runs approximately in the extension of a side edge 51 of the claw plate 46, while the other claw 32 or its claw web 42 runs at a distance from a side edge 53 of the claw plate 46 which is arranged approximately parallel to the side edge 51 . These two joint brackets 48, 50 are encompassed by two side cheeks 58, 60 of the pivoting plate 36, the linkage 52 indicated by dot-dash lines being formed in the overlapping area. In the representation according to figure 5 one can also see the swivel joint 54, via which the swivel plate 36 is connected to the end fitting 24 in an articulated manner. This connection takes place at a distance from linkage 52, also in the area of side panels 58, 60, with end fitting sections 62 that are reduced in width (only one in figure 5 provided with a reference number) into the area between the two side walls 58, 60 and is connected there via the pivot joint 54 to the pivot plate 36. The handle 56 extends as shown in FIG figure 5 upwardly beyond the pivot joint 54.

figure 6 shows the trapezoidal closure 26 in the closed state, in which the maximum tensile stress is applied via the straps. In this closed or clamped position, the pivoting plate 36 is shown in FIG figure 6 To the right, pivoted toward the claws 32, 34, with the end fitting 24 being arranged in alignment with the pivot plate 36 approximately in the circumferential direction of the trapeze belt 1. In the representation according to figure 6 one can clearly see the two joint brackets 48, 50 dipping into the side walls 58, 60, which are connected to one another in an articulated manner via suitable joint axes, for example by means of bolts inserted into the side walls 58, 60.

A swivel joint, via which the end fitting 24 is connected to the swivel plate 36, is shown in FIG figure 6 The exemplary embodiment illustrated is designed in such a way that articulated webs 64 on the end fitting 24 on the one hand and articulated webs 66 on the swivel plate 36 on the other hand interlock alternately, so that the swivel joint is designed with great stability and it is ensured that the tensile force is transmitted in the predetermined manner without twisting the components .

figure 7 shows an exemplary embodiment in which the entire trapezoidal lock 26 with the claws 32, 34 of the claw plate 46, the pivot plate 36 articulated thereon and the end fitting 24 articulated to the pivot plate 36 are made of fiber-reinforced plastic, so that the manufacturing costs are lower than in the case described above embodiment are. However, these fiber-reinforced plastics ensure that the tensile forces that occur are transmitted without any unwanted deformation/elasticity.

A trapeze lock and a trapeze belt are disclosed, with two approximately hook-shaped claws preferably being formed on a closing piece of the trapeze lock, which can be brought into non-positive and positive engagement with a retaining element formed on a hook plate.
