Abstract

Disclosed are a trapezoidal hook and a harness made with such a harness hook and a hook plate made with such a hook, with a hook of the harness hook being assigned a slidably guided securing element.

Description

The invention relates to a harness hook according to the preamble of claim 1 and a harness made therewith.

Such harness straps are used in sailing, kitesurfing and also in windsurfing as well as in beach sailing, in particular with windsurfing sails and kites, in order to hang onto a trapezoidal ring, a harness line or a chicken loop. The harness hooks used in sailing often have a securing element which is resiliently arranged in the space around which the hook is gripped and which closes the hook opening so that a trapezoidal ring of the trapezoid cannot accidentally slip out, for example during a turn in which the trapezoid is relieved. To release the trapezoidal ring, it is then unhooked against the spring force of the securing element.

When kiting, a chicken loop connected to the front lines of a kite is hooked into the harness hook of the harness so that the kite's tensile force is essentially transmitted to the kiter via the chicken loop and harness. The harness hook of the harness is designed in the shape of a frame, so that when the chicken loop is hooked in, a securing element - also called a chickendick - can be hooked into a central opening of the harness hook in order to secure the chicken loop on the harness hook. The handling of this securing element is relatively complex, so that handle-pass maneuvers in which the chicken loop must be unhooked are more difficult. Even beginners are often overwhelmed with the proper handling of such a safety element.

From the pamphlet WO 2007/000 787 A1 a generic harness hook is known in which a securing strip is attached to the harness hook which has a recess into which a bolt is inserted to secure the chicken loop. This bolt is held on a plate, which in turn can be fixed in position on the securing strip by means of a quick-release fastener, for example a Velcro fastener.

Such a solution is disadvantageous in practice since it is extremely difficult to grasp the bolt that is not in a defined position and then insert it into the recess while driving or on the beach when the kite is launched.

In the WO 2003/037 708 A1 a trapezoidal hook is shown in which a pivotable securing element is fixed in position via a spring-loaded locking bolt. This harness hook has an extremely complex structure. Another disadvantage is that this concept is not suitable for fixing a chicken loop in position.

Concepts with a "panic snap" as used in the DE 10 2013 007 433 A1 were used in the early years in kite sports and replaced by the generic concepts due to significant functional deficiencies.

The document JP 2000 - 280 978 A describes a spring-loaded harness hook, which is designed to dampen sudden loads.

Accordingly, the invention is based on the object of creating a harness hook and a harness made therewith or a hook plate made therewith, in which the handling is simplified with improved operational reliability.

This object is achieved with regard to the harness hook by the features of claim 1 and with regard to the harness / hook plate by the features of claim 11.

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

The trapezoidal hook according to the invention has a hook which can be attached to a hook plate and to which a securing element for securing a functional part suspended in the hook, for example a chicken loop, is assigned. According to the invention, the securing element is slidably guided in a guide on the hook side. With this guide, the opening and closing of the opening around which the hook is gripped for securing / removing the functional part is significantly simplified compared to the solutions described above, with a malfunction being almost impossible due to the guide. The guide is designed in such a way that the functional part is reliably secured in position even under high tensile loads and cannot be accidentally released from the hook.

The handling of the trapezoidal hook is particularly simple, since an end section of the locking bolt overstretched the free hook end, so that the locking bolt can be actuated directly from the outside by attaching the chicken loop or a trapezoidal ring or the like.

The functional reliability can be further improved if the securing element is pretensioned in the direction of a closed or secured position.

In one embodiment it is provided that the closing element is in the open position to be able to deliberately determine, for example to simplify handle-pass maneuvers.

The trapezoidal hook can be made particularly compact if the securing element is guided displaceably, for example, in a plane encompassed by the hook.

In a particularly preferred embodiment, the securing element is designed with a spring-preloaded locking bolt, which in the securing position is supported by an end section on the hook.

Such a support can take place, for example, via a projection which points to the area around which the hook engages.

To fix the position in the securing position, a centering device can be provided by means of which the securing element is fixed in relation to the hook.

In one embodiment of the invention, the guide for the securing part is formed on the hook, a locking bolt of the hook being displaceably guided along this guide, which is pretensioned in its closed position by the spring.

The guide can be carried out particularly easily when it penetrates the hook.

In a variant of the invention, the hook is designed with a guide pin on which the spring is supported.

In a variant of the invention, this guide pin can penetrate a receptacle of the locking bolt in which the spring is received.

In a particularly convenient embodiment, a pulling means is provided, via which the locking bolt can be brought into an open position.

The guide can be designed in a particularly simple manner if the hook has an enlarged base on the hook plate side in which the guide of the locking bolt is received or formed.

A trapezoidal hook of this type can be retrofitted relatively easily even in existing trapezoids.

1 shows a three-dimensional representation of a first embodiment of a trapezoidal hook 1 , for example on a hook plate indicated by dash-dotted lines 2 - also called spreaderbar - can be fastened. This hook plate 2 is in turn part of a trapezoidal belt, for example in the European patent EP 2 835 309 B1 is described by the applicant. To avoid repetition, reference to this publication does not include explanations about the basic structure of a trapezoidal belt.

The harness hook 1 has a hook designed as a profile body made of plastic 4th , which is shown according to 1 and also in the usual position of use, seen in the direction of gravity, bulges downwards and forms a hook space 6th encompasses. That hook 4th extends from a hook base 8th which, as shown in 1 to the hook plate 2 expanded towards trapezoidal or triangular shape. There are mounting brackets on both sides of this base 10 trained, of which in 1 only one is visible and the one for attachment to the hook plate 2 serve.

In the illustrated embodiment, the hook 4th , the base 8th and the mounting brackets 10 formed in one piece from fiber-reinforced plastic, for example by injection molding or by a generative process, for example 3D printing. According to the invention, the hook space 6th from a fuse element 12th locked so that one in the hook room 6th recorded chicken loop cannot slip out. At the in 1 The solution shown is in that of the hook plate 2 widening hook base 8th a guided tour 14th provided in which a locking bolt 16 Is guided longitudinally displaceable. In the in 1 This shifting takes place in the vertical direction (see arrows in 1 ).

In the illustrated embodiment, the locking bolt is 16 executed with an approximately rectangular or square cross-section and biased by means of a spring described in more detail below in the illustrated closed position. According to the cross section of the locking bolt 16 is the lead 14th with an approximately rectangular or square guide recess 18th executed in which the locking bolt 16 is guided with a sliding fit. In the 1 invisible spring 20th (see 5 ) is in a spring holder 22nd of the locking bolt 16 picked up and supported with her in 1 overhead end portion to a guide pin 24 starting with the hook base 8th across the direction of displacement or across the locking bolt 16 asserts itself through the spring mount 22nd extends therethrough. That is, this guide pin 24 also contributes to the exact guidance of the locking bolt 16 at. As explained, the spring is 20th on the guide pin 24 supported and engages on a floor 26th the spring mount 22nd so that the locking bolt 16 by the pen 20th is biased towards the illustrated closed position. In the area of a hook end 28 is to the hook room 6th towards the locking bolt 16 a head start 30th formed, which becomes the hook space 6th towards the end of the hook 28 supports.

An actuator head 32 of the locking bolt 16 is widened compared to its guide section and extends approximately as an extension of the hook end 28 . In other words, the widened actuator head 32 joins the in 1 end face of the hook end pointing obliquely backwards 28 at.

How continue the 1 removable is an overhead end section 34 of the guide pin upwards out of the guide recess 18th led out. At this end section 34 grips a traction device, for example a loop 36 through which the locking bolt 16 can be brought into its open position.

In 1 Also visible is one on the ledge 30th opening centering recess 38 provided, in which a hook-side centering projection 40 (see 2 and 3 ) so that the closed position is secured.

2 Figure 12 shows a view of one on the hook plate 2 mounted harness hook 1 , which has a slightly different structure than the embodiment according to 1 having. In this embodiment is in the area of the guide 14th at the base 8th a bulge 42 provided, which is formed so that the above-described end portion 34 of the locking bolt is flush with the bulge 42 ends. The loop 36 is with the in 2 The illustrated embodiment is not in the form of a band, but is formed by a rope. In this representation you can clearly see how the one to the hook room 6th cantilevered projection 30th on the hook end 28 rests, the centering projection 40 fits exactly into the centering recess 38 immersed and thus the locking bolt 16 Secures against bending. Its actuating head 32 extends, as stated above, approximately as an extension of the hook end 38 .

3 shows the harness hook 1 according to 2 in the open position. This opening position is in 3 achieved by the loop 36 a tensile force is applied which is greater than the preload force of the spring 20th is so that the lead 30th from the hook end 28 lifts off and accordingly also the centering projection 40 from the centering recess 38 is moved out. This position is assumed, for example, to release the attached chicken loop.
The centering projection 40 ensures that this also occurs in the event of an accidental displacement of the locking bolt 16 instantly slipping out of the hook 4th is prevented. In this open position is in the 2 and 3 overhead end section 34 of the locking bolt 16 from the leadership 14th led out.

4th shows the insertion of the closed chicken loop. This is with your in 4th lower parting 46 to the actuating head 32 scheduled. Then the locking bolt is activated by applying force in the direction of the arrow 16 against the bias of the spring 20th (see 5 ) off the hook 4th lifted off, so that then in accordance with 5 the chickenloop 44 in the hook room 6th can be introduced. Once the chickenloop 44 except for operative engagement with the locking bolt 16 , or more precisely with the actuator head 32 reaches the locking bolt 16 by the force of the spring 20th brought back into its closed position in which the projection 30th on the hook end 28 rests. The centering projection 40 then dips back into the centering recess 38 one. Loosening the chicken loop 44 then takes place by pulling on the loop 36 (see 3 ).

The solutions described above are much more reliable and easier to use than the solution mentioned at the beginning with a chickendick. In addition, the position of the chicken loop is fixed 44 within the hook space 6th guaranteed even with unfavorable lever conditions, for example during a suspended freestyle maneuver.

Disclosed are a trapezoidal hook and a harness made with such a harness hook and a hook plate made with such a harness hook, with a hook of the harness hook being assigned a slidably guided securing element.
