DESCRIPTION

Trapeze and trapeze closure

The present invention relates to a trapeze closure for a trapeze for practicing kiteboarding, windsurfing or sailing according to the general concept of claim 1, as well as to a trapezoid provided with a trapezium closure of this type.

The trapezoids equipped with this type of trapezoidal fasteners can be made as a hip trapeze or as a trapeze seat and usually have a trapezium hook that is attached to a front bracket or a front plate. In this front plate is attached a strap with a padded back piece, which in the area of the lumbar vertebrae is provided with pads or something similar. Because, for example, in kitesurfing the forces introduced through the kite act relatively strongly in the vertical direction, particularly in the hip trapezoids, it is important that they fit well. Correspondingly, the trapezius should be applied relatively tightly to the body, to prevent its sliding. To simplify this placement, the trapezoids usually have a trapezoid closure, in which an element similar to a carabiner hooks into an eyelet, in which by means of adjustable straps between the plate or the front bracket, respectively, and the piece from back an adaptation to the circumference of the hip is possible.

In this regard, it is problematic that the carabiner has to be hooked in the eyelet by applying a relatively large force, to ensure exact adjustment of the trapezius to the hip. Particularly problematic is also releasing the closure, since to release the carabiner it is necessary to apply a corresponding pre-tension to be able to disengage the carabiner.

In document DE 202004006 143 U1 a solution is described, in which the carabiner hook is secured in the eye by means of a suspension shackle and by means of a handling element can be brought from its locking position to a position of liberation. Specifically, this manipulation element can be made as a pull tab, through which the surfer can apply a comparatively large force for opening.

However, also in this variant it is problematic that the hook of the carabiner in the eyelet continues to be difficult, since for the closure it is necessary to insert the hand between the carabiner and the body, in order to apply the required traction force.

For this reason, numerous surfers loosen the strap bands for adjustment, then engage the trapeze closure and then re-tension the strap bands - comparatively, this is very complicated.

Document NL 1029 515 C1 shows a trapezoid closure according to the type, which has a pivoting locking lever, which can be put into active engagement with an eye for the adjustment. Also in this solution, the closing lever has to be fastened when engaging in the eyelet, so that this way of handling is also complicated.

Against this, the aim of the present invention is to create a trapeze closure and a trapezoid equipped therewith, in which handling is simplified.

This objective is achieved through a trapezoid closure with the features mentioned in claim 1, as well as through a trapezium strap equipped with a trapezium closure of this type according to claim 14.

According to the present invention, the trapezoid closure has devices, for example, eyelet is for coupling the trapezium belt itself, as well as a locking part that can be put in interlocking engagement with a retention element of approximately cancel. This closing piece can be brought into a latching position, in which the holding element is secured in its position, but is not yet tensioned in its closed position. According to the present invention, the closure part can then be changed from a hooking position to a closing position, in which the holding element is tensioned with the closing part, in such a way that the stretched length of the closure trapezoidal in the engaged position is substantially greater than in the closed position.

This concept of a trapezoid closure allows first the retaining element to be engaged with little force in the closing part, in such a way that the trapezium belt is fixed in its position. The tension force required for the correct application of the trapezoid is then generated by adjusting the closure piece in its closed position, in such a way that the comfort when closing and opening the trapezoid closure is substantially improved compared to conventional solutions.

In an exemplary embodiment of the present invention, the closing part is formed as a pivoting lever which is pivotally supported on a base about a pivot axis, in a first section of end of the pivoting lever is formed a clamping hook. In a variant, a closing hook can be formed in a second end section. In a spaced apart manner with respect to the clamping hook or, respectively, in the region between the clamping hook and the closing hook, a pivot axis is provided. To fix the position of the closure piece in the closing position, according to the present invention some other reversible insurance is provided, for example, a latching device or something similar.

According to the present invention, it is preferable if the distance of the clamping hook with respect to the axis of rotation is greater than the distance of the closing hook with respect to the axis of rotation, in such a way that the pivoting lever is made, so say it, with a longer lever arm and a shorter one. The longer lever arm acts on the latch, while the shorter lever arm determines the holding position. The clamping path can be, for example, greater than 10 mm, preferably approximately 30 mm. The construction of the trapezium lock is particularly simple, if the hooks are mutually oriented approximately U-shaped.

The retaining part can then slide during the rotation of the pivoting lever along the same from the hooking position to the closing position.

In order to prevent accidental release of the pivoting lever from the closed position, it can be inserted in the closed position between two deflector bends of the base.

The pivoting lever can be supported on a console, with which the pivoting lever is brought into contact in the closed position, so that the axis of rotation is not loaded with excessive tensile forces.

In an alternative solution, the trapezoid closure is designed as a rotating ball joint. Specifically, the closing part is then embodied as a rotatably supported eccentric, which is surrounded by the annular retaining element, such that with a conference section the interior abuts an outer circumferential section of the eccentric.

The axis of rotation of the eccentric is selected in such a way that in the engaged position the distance of the inner circumferential section of the annular retaining element towards the axis of rotation is smaller than in the closed position. By rotating the eccentric, the required tension force can be generated in a comparatively comfortable manner.

To facilitate rotation, the eccentric can be made with a manipulation element.

Also in this variant, an accidental opening can be prevented if a stop is provided on the side of the closing part, which in the blocking position is arranged so close to the eccentric that the retaining element is prevented from releasing from its position. position embraced around the eccentric.

The fixing of the position of the ring-shaped or eye-shaped retaining element is particularly simple, if a groove is provided in the outer circumference of the cam to accommodate the sections of the inner circumference of the retaining element.

In a very compact embodiment of the present invention, the closure piece is fastened on a plate, on which the trapezium hook is also fixed.

Preferably, the retaining element may be provided with eyelets for an adjustable strap band to adapt to the circumference of the body. Correspondingly, the plate is also made with eyelets. The retaining element is preferably designed as a mostly closed annular body, which can be engaged on the pivoting lever or which can also surround the eccentric. This results in a surface contact between the closure body and the retaining element, so that the torsion (twisting) of the trapezoid closure can be reduced by this form-fitting contact.

The manufacture of the trapezium clasp is particularly simple, if the retaining element, the closing part, the plate and preferably also the trapezium hook are made of plastic, preferably by the injection molding technique.

Preferred embodiments of the present invention are described in more detail below with reference to the schematic drawings. In the drawings:

Figure 10 shows the trapezium closure of figure 7 in the closed position.

Figure 1 shows a strongly simplified representation of a trapezium belt, which is made as hip trapezium 1. This has a hip belt 2, with a back piece 4, which in the area of the lumbar vertebrae can be equipped with pads and / or appropriate padding. This hip belt 2 encloses the hip area on the back side and laterally. On the front side, by means of adjustable strap bands 6, 8, a front bracket or a front plate 10 is provided, in which a trapezium hook 12 is attached 12. In this trapezium hook 12 it is possible to engage, for example , a loop type "chicken loop." To adjust the hip trapeze 1, the hip belt 2 can be opened by means of a trapezium closure, which in the following will be called as closure 14.

In the representation according to FIG. 1, the belt bands 6, 8 are represented in a greatly simplified manner - in practice, however, each belt band 6, 8 is formed by several belt cords, on the one hand they are sewn with the hip belt 2 and, on the other hand, are respectively linked in the end fittings 16, 18. The end fitting 16 is directly connected to the front plate 10 and the end fitting 18 is integrally made with the retaining element 38 of the closure 14. The length of the strap bands 6, 8 can be adjusted by means of adjustment devices, not shown, in such a way that the front plate 10 can be arranged centrally.

To link the belt bands 6, 8, the end fittings 16, 18 are provided with slots 20, 22, whose bridges are surrounded by the respective belt band 6, 8.

The basic structure of the closure 14 can be seen particularly well in the top view shown in Figure 2. Accordingly, a console 24 is formed on the front plate 10, on which a pivoting lever 26 rests. rotatably about an axis of rotation 28. According to the front view shown in figure 1, this console 24 has two console branches 30a, 30b, between which the pivoting lever 26 is received and through the passing the axis of rotation 28.

The pivoting lever in its widest sense has a U-shaped profile, in which in the end sections on the one hand a clamping hook 32 is formed and, on the other hand, a closing hook 34, which are oriented one towards the other. The pivoting lever 26 extends a little above the clamping hook 32 to form a gripping part 36. In this clamping hook 32, in the engaged position of the trapezium lock 14, a retaining element 38 is engaged, which in FIG. the exemplary embodiment shown is made in one piece with the end fitting 18. As can be seen in the illustration according to FIG. 1, in the engaged position the distance A between the annular retaining element 38 and the shaft of rotation 28 is relatively large, such that correspondingly the circumference of the hip trapezium 1 is maximal. In this regard, the strap band length is adjusted in such a way that the hip trapezium 1 in the position shown in Figure 1 can be closed without difficulty by the surfer.

In this latching position, however, the hip trapezium 1 is only held loosely at the hip. In order to tighten it, according to FIGS. 3 and 4, the pivoting lever 26 is then rotated about the axis of rotation 28 by approximately 180 ° until it reaches its tension position. In this, the comparatively long partial section of the pivoting lever 26, which is provided with the clamping hook 32, in the representation according to FIG. 2 first rotated downwards, in the direction towards the faceplate 10, while the part shorter of the pivoting lever with the closing hook 34 rotates towards the console 24, that is, to the area between the two console parts 30a and 30b. This rotation is effected by means of the handle part 36, which can be reached relatively easily by the surfer. During rotation, the annular retaining element 38 slides along a base 40 of the pivoting lever 26, until it comes into contact with the rotated closing hook 34 - this relative position is shown in Figures 3 and 4 .

In this closing position, the retaining element 38 also comes into contact, or substantially comes into contact, with a choker 62 formed by the console pieces 30a, 30, in such a way that no or only a few stress forces are introduced. on the axis of rotation 28. To lock the rotational position of the pivoting lever 26, an engaging bead 42 is provided on the front plate 10, which meshes with the holding hook 32, so that it is secured in its position on the front plate 10. For opening, this engagement relationship can be released by a reversing rotation of the pivoting lever 26 by means of the handle part 36. The lever length of the pivoting lever 26 is comparatively large, in such a way that also a surfer of less physical strength can apply without problems the force of tension required to fix the trapezium belt. As already mentioned above, the tension path is approximately 30 mm.

In FIG. 4, a hook-and-loop fastener 48 is also shown with broken line, with which the strap 2 can be pre-fixed and which also prevents the comparatively hard front plate 10 from coming into direct contact with the body.

Figure 5 shows a variant of the embodiment according to figures 1 to 4. In it a detail view from above is shown on the closure 14 in the closed position. In this embodiment, on the front plate 10, which is normally centrally covered with a neoprene shield, two baffle shoulders 44, 46 are formed, between which the clamping hook 32 is immersed with the handle part. 36, in such a way that an accidental opening is prevented, for example, because the handle piece 36 is caught in a rope or the like.

According to the present invention, the front plate 10, the end fittings 16, 18, the pivoting lever 26 and the other elements of the closure, preferably also the trapezium hook 12, are preferably made of plastic, in such a way that the manufacturing is extremely simple. Obviously, for this only high quality reinforced plastic materials are used, which can withstand the forces that arise in the practice of windsurfing or kitesurfing.

In the representation according to figure 6, the construction according to figures 5 is shown in the open state. One can clearly see the annular retaining element 38 hooked on the clamping hook 32 and the closing hook 34 projecting upwards from the pivoting lever 26, projecting from the two console parts 30a, 30b; the latter are traversed by the axis of rotation 28. On the right next to this the baffles 44, 46, which have to be minimized in weight, are provided with an opening, in such a way that the retaining hook can be seen 42

On the basis of FIGS. 7 and 10, an exemplary embodiment of a belt 2 is described, in which the trapezoidal closure 14 is embodied as an eccentric seal. The basic construction of the trapezium belt with its hip belt 2, the trapezium plate 10, the trapezium hook 12 and the end fittings 16, 18 for adjusting the circumference of the hip belt corresponds to the embodiment described above, in such a way that reference can be made to this description.

In the representation according to figures 7 and 8, the eccentric closure 14 is shown in its latching position, in which it can be positioned forward at the surfer's hip. Subsequently, the tension of the trapezoid closure 14, which is described in the following, is then carried out. The details of the closure 14 are described on the basis of FIGS. 9 and 10. In this regard, FIG. 9 shows the closure 14 in the latching position which is also shown in FIGS. 7 and 8. In FIG. 8, the FIG. closure 14 is adjusted in its closed position.

In the variant according to FIGS. 7 to 10, an eccentric of approximately cylindrical shape 50 is supported on the front plate 10, which can be rotated about an axis of rotation 52. It is displaced (seen according to FIG. 9). ) with respect to the geometric center of the eccentric 50, such that the distance a to the right apex 54 in FIG. 9 is smaller than the distance b of the left apex 56 in FIG. 9. The retaining element of substantially annular shape 38 connected to the end fitting 18 surrounds the eccentric 50 in sections. The internal diameter of the retaining element 38 is so large that it can easily surround the eccentric 50, as shown in FIG. 9. This is made with a manipulation element 58 that extends in the diagonal direction, in such a way that can be easily twisted.

The circumferential surface of the eccentric 50 is made with a slot 51 or choker (indicated by an intermittent line in FIGS. 8 and 10), in which the annular retaining element 38 is submerged in sections. Correspondingly, it is gripped around the a portion of the eccentric 50 and is held relatively securely within the annular groove, such that accidental detachment in the engaged position is prevented. At a predetermined distance from the axis of rotation 52 of the cam 50, trapezoidal plate 10 is provided with an abutment 60 formed as an annular sector, wherein the distance X is selected in such a way that the retaining element 38 it can support the eccentric 50 in an enveloping manner.

In the representation according to figure 10, the eccentric 50 is rotated by 180 ° towards its closing position, in such a way that the other vertex 56 is oriented relative to the stop 60. Because the distance b from the vertex 56 is substantially greater than the distance a from the other vertex 54 with respect to the axis of rotation 52, correspondingly the annular retaining element 38 is dragged in the clamping direction, ie towards the stop 60, in which in this closing position the distance between the stop 60 and the vertex 56 is so small that the annular retaining element 38 can not be released from the circumferential section of the eccentric 50. According to this representation, also the radius The curvature of the stop 60 is adapted to that of the outer circumference of the eccentric 50. In this representation it can be seen that practically the entire part of the retaining element 38 that surrounds the cam 50 is immersed within the annular groove 51 indicated in FIG. eccentric 50, so that it is no longer visible in the top view according to Figure 8, and thus is reliably fixed in its position. In the closing position according to FIG. 10, the distance d of a base 66 of the retaining element 38 is greater than in the latching position (FIG. 9).

Due to the surface-smooth configuration of the eccentric closure according to FIGS. 7 and 8, the possibility of an accidental opening is practically excluded. This exemplary embodiment is also substantially made of plastic material.

In all the described variants, the trapezoid closure is very rigid to the torsion due to the surface contact and force drag between the closing part (pivoting lever 26, eccentric 50) and the retaining element, in such a way that it is minimized possible twisting of the trapezium belt. In addition, in this way an accidental opening of the trapezoid closure under tension is prevented.

As previously mentioned, the retaining element 38, in a manner similar to the previously described embodiment, is integrated into the end fitting 18 and preferably is made in one piece with it. Obviously, it is also possible to fasten the retaining element to the end fitting 18. The inner diameter of the retaining element 18 is adapted, as previously mentioned, to the diameter of the eccentric 50, such that the latter, in the position of engagement, is wrapped by the retaining element 38 in the manner shown in Figure 9.

The stop 60 and the eccentric 50 are preferably arranged on a common support plate, in which the axis of rotation 52 is anchored on this support plate 64. As previously mentioned, the main components of the trapezium closure 14 they can be made of plastic, for example, a fiber-reinforced plastic, through an injection molding process.

The described trapeze can be made as a trapeze for kitesurfing or as a trapeze for windsurfing. In this regard, a variant can be made as a seat trapeze or as a hip trapeze.

It discloses a trapezium lock and a trapezoid equipped with a trapezium lock of this type, in which the lock is made with a latching position and a closing position.
