to Fixing brackets, fittings and / or the like connection and / or fasteners, such as boat roof fittings, in or on a wall of a boat, a caravan and / or the like, usually made of plastic and / or wood walls in practice so far only a few millimeters thick screws directly screwed into the wall. The anchoring of the screws in wooden walls for example boat walls, is relatively durable, since the screws over their entire length and full grab in the wall. For most boats, the outer wall is usually however, from a plastic skin only a few millimeters thick, in which when fastening by means of screws accordingly only few of the threads which also usually only a few millimeters thick screws stop should find. The rest of the threaded portion of the screws is therefore on the inside of the outer wall free and is especially in plastic boats with double skin trained walls unused - because inaccessible - in the empty one Room. As screws usually come so-called neck screws for application to the same even with a single-shell construction method Wall of a boat or caravan not even one accordingly small nut can be turned on or screwed on.

On the short and small wall / screw connection for fixing a bracket or a fitting on the wall looks outside the wall about a double to triple leverage, that the screws are outside the ship's side usually first wear a small washer, the shaft of the screw on it subsequently to Einschraubmöglichkeit as a polygon and then trained as a neck, on top of that still wearing a head, For example, a ball head or the like configuration, on or on the accordingly of the wall abundant spaced the leverages at the end attack, for example in the form of a right angle to the screw extension direction attacking pulling force of a cover textile in a boat.

The extremely unfavorable conditions between attacking or acting leverage and very little contact or anchoring surface between the few also very small Schraubgewindegängen the wall / screw connection cause a frequent breakout the screws from a wall, for example, already through the a wind cloth effecting a cover textile or by being caught with clothes or ropes, by kicking and / or the like. The then necessary repair then unsatisfactory way, usually using synthetic resin, the problem described in US Pat the application occurring and absorbed forces of the wall / screw connection and thus their susceptibility to breakout unchanged remains.

adversely is about it Beyond that, an elevated Personal and property damage potential from the screws emanates because their heads protrude considerably from the wall or protrude from it, especially during the times without covering with a soft top textile.

Of the Invention is the object in view of this prior art at least, however, to remedy the abuses mentioned above to reduce.

to technical solution is with the present invention, a threaded insert, preferably for Consolidation in or on a wall of a boat, a caravan and / or the like, proposed with a substantially bolt-shaped body, which an external thread, a central blind hole with an internal thread to accommodate one with the female thread screwed fastener and on a End, preferably the end surrounding the entrance of the blind hole, a hoof bearing surface for the wall having providing plate-like projection.

Of the Invention is based on the finding that by using a appropriately designed threaded insert in contrast to the usual used thin Screws with a low thread surface, especially by use one in diameter larger bolt-shaped body with an external thread a much larger contact surface for the wall / screw connection the bolt-shaped body given, whereby a comparatively much larger mechanical Stop of the threaded insert in the wall is reached. In addition will be the described, unfavorable acting leverage forces through the threaded insert according to the invention over the preferably selected over a large area, by transferred the plate-like projection formed collar of the bolt-shaped body and are thus advantageously minimized as far as possible.

object In addition, the present invention provides a fastening system a holder for an eyelet of textiles, tarpaulins, straps or the like that are in, on or with the holder fixed state - Arretierungs- or Locking condition - the eyelet under a permanent tension, with the holder the eyelet in this Condition - locking position - passes through and stops in or on a wall of a boat, a caravan and / or like, comprising a threaded insert according to the invention, a holder for an eyelet and a Screw as a fastener to attach the bracket the threaded insert, wherein the holder as one with a protruding from the opening of the eyelet Locking nose or tongue about a pivot axis rotatable base with elliptical or oval cross-section is formed, wherein the Pivot axis either coincides with the center of the ellipse or on the minor axis of the ellipse is shifted from the center and at which the locking nose or tongue diametrically opposite A shoulder is formed on which under tension the eyelet to pull and then the locking lug or tongue by 180 ° in its locking position and to pivot from this by a new turn by 180 ° in their release position is.

The Holder of the system according to the invention guarantees are doing a advantageously a selbstsichemde support function draws through a flat, material and personal injury preventive form and can also be in one piece and - like the whole system - made of indestructible, Shatter-proof, weather-resistant and UV-resistant materials getting produced.

• – Bei einer Anordnung der Schwenkachse im Mittelpunkt der Ellipse mit gleichen Abständen der Schwenkachse sowohl von der Schulter als auch von der dieser gegenüberliegenden Sockelwandung bleibt die Zugspannung nach herübergezogener Öse auf die Schulter gleich der Zugspannung in der Verriegelungsposition. Zwischen diesen beiden Positionen wird aufgrund des elliptischen oder ovalen Querschnittes des Sockels bei Überschreiten der Scheitelbereiche der Hauptachse der Ellipse die Zugspannung kurzzeitig kräftig erhöht. Diese Erhöhung der Zugspannung, die sowohl eintritt, wenn die Halterung von der Loslage in die Verriegelungsposition als auch umgekehrt von der Verriegelungsposition in die Loslage überführt wird, bildet eine automatische Selbstsicherung.
• – Aufgrund der flach aus der Ösenöffnung herausragenden und diese in einem Teilbereich des Ösenrandes übergreifenden Riegelnase bzw. -zunge weist die gesamte Halterung einen äußerst flachen Aufbau auf.
• – Nachdem die Öse auf die Schulter der Halterung gezogen ist, benötigt die Halterung nur noch eine 180°-Drehung um von der Loslage in die Verriegelungsposition überführt zu werden. Dies kann mit einem einfachen, noch nachfolgend zu beschreibenden Werkzeug erfolgen. Ein Verschieben oder Ziehen eines weiteren Teiles ist nicht erforderlich.
• – Nach dem Verschwenken in die Loslage gleitet die Öse unter der immer noch bestehenden Zugspannung automatisch von der Schulter herab in ihre Loslage.

In addition, the embodiment according to the invention has several serious advantages:

• - In an arrangement of the pivot axis in the center of the ellipse with equal distances of the pivot axis of both the shoulder and of this opposite Sockelwandung the tension remains after pulled eye on the shoulder equal to the tension in the locked position. Between the sen two positions due to the elliptical or oval cross-section of the base when the apex areas of the major axis of the ellipse is exceeded, the tensile stress is briefly increased sharply. This increase in tension, which occurs both when the holder is transferred from the release position to the locking position and vice versa from the locking position to the release position, forms an automatic self-assurance.
• - Due to the flat protruding from the eye opening and this in a portion of the Ösenrandes cross locking nose or tongue, the entire holder has an extremely flat structure.
• - After the eyelet has been pulled onto the shoulder of the holder, the holder needs only a 180 ° turn to be transferred from the release position into the locking position. This can be done with a simple, yet to be described later tool. Moving or pulling another part is not required.
• - After pivoting into the release position, the eyelet automatically slides from the shoulder into its release position under the tension which still exists.

Of the Selbstsicherungseffekt the bracket comes advantageously automatically This is due to the fact that the main axis of the ellipse or of the oval in the locking position of the holder perpendicular to Direction of the tension runs. This automatically ensures that when pivoting 180 ° below Significant, targeted effort a "top dead center", namely one the two major vertices of the major axis of the ellipse are exceeded must become. This main vertex is already after a 90 ° turn reached the base with the elliptical or oval cross-section. After that falls this increased tension back to the original, desired Tension off, which occurs when the eyelet on the shoulder of the bracket is pulled.

there is the outer circumference the shoulder is approximately identical to the big elliptical or oval bow.

To an advantageous development of the invention, the locking lug protrudes or tongue so far over the inner elliptical or oval arc beyond that the sum of the lengths of shoulder and locking nose or tongue does not exceed the size of the diameter of the opening of the eyelet. This will be an extremely compact embodiment ensured and by the position of the locking nose or tongue at the same time the locking position or the release position displayed.

Advantageous the locking nose or tongue is formed relatively wide, goes into the Contour of the shoulder over and extends in the locking position flat over a Part of the eyelet edge. Due to the wide-area Training both the locking nose or tongue and the shoulder punctual loads are prevented. By the flat attack the locking nose or tongue over a portion of the eyelet is an unfavorable above construction - like in the prior art - avoided.

To a particularly advantageous embodiment of the invention the screw forming the pivot axis protruding from the well bore cylindrical part on the shell of a cylindrical opening of the Socket on. It supports the screw head with a flange-like extension above this cylindrical opening on a shoulder of the base. This is the transfer the tensile forces of the textile, the tarp or the belt over a portion of the eyelet on one the two big ones elliptical arcs of the base and of its cylindrical shell on the cylindrical Part of the screw. Because this cylindrical part of the screw immediately nearby the wall or rail is only a very short Lever arm for power transmission existing with the result that the turning and bending moments on the Socket to be minimized. The attachment of the screw head on one Paragraph of the base provides for an always secure attachment of the bracket in the direction of the pivot axis.

Of the Head of the screw can be as Phillips, diametrical slit or with an internal polygon contour are formed. For the approach of a train and swivel tool for The bracket proves to be beneficial to the head of the screw to provide a blind hole. This blind hole serves for centering Intervention of a form-fitting Storage of a pivot axis of the used and to be described Tool.

At The underside of the base is advantageous in a return an entropy-elastic disc arranged under the on the Socket exercised Compressive tension of the screw under a spring preload set is. On the one hand, the screw hole from moisture penetration to protect and on the other hand the pedestal under the frictional forces with the wall or the Keeping rail in any position is about the thickness and about the specific one Entropieelastität the disc whose spring preload in the end position of the mounting position to dimension the screw accordingly.

Advantageously, the main axis of the ellipse or the oval of the socket with respect to the inner diameter of the eyelet to be dimensioned so that for pivoting the apex areas of Hauptach the ellipse or oval is required to overcome a brief, strong, targeted tension of the fabric, tarp or belt or the like in which this respective eyelet is located. After pulling the eyelet on the shoulder in the release position, the desired tension has already been reached. As soon as one of the main vertices of the main axis of the ellipse or the oval grinds along the inner edge of the eyelet after a 90 ° rotation, this tension increases considerably before the locking position of the holder with the eyelet is reached under the originally applied tensile stress and remains below this original tensile stress ,

To For this purpose, the invention makes the limited elasticity the eyelets absorbing textiles, tarpaulins or straps.

To a particularly advantageous embodiment of the invention is the inner elliptical or oval arch in at least one subarea of the pedestal formed as an inclined plane, among which and the Effect of tension the eyelet in the locking position of the bracket automatically to the wall or rail is used. Through this attraction to the Wall or rail only becomes attacking wind and water forces a minimal attack surface offered and, for example, a Persenningumrandung splash-proof. By a corresponding displacement of the center of the elliptical Sockets or oval on the minor axis, this tension can be arbitrary changed and be sized so that in the locked position when needed also a larger tension can be reached is as in the Loslage position.

To the Approach of a tool is the locking nose or tongue on her Top center with a groove and centered on her shoulder a notch provided.

Around the vertex area of the major axis of the ellipse or the oval as possible To keep small, there is the elliptical or oval cross-section of the base of two overlapping ones Circles with a radius (radius) that is slightly smaller as the inner diameter of the eyelet is.

Of the Base is advantageous with the locking nose or tongue and the shoulder made in one piece from plastic, aluminum or seawater resistant stainless steel. As far as these parts are made of aluminum, they can be hard-anodized and arbitrary be colored. If they are made of plastic, this is a UV and seawater resistant Select material.

The Locking nose or tongue is at its free end and the shoulder at its the wall or the rail facing area for engaging behind resilient tongues of a blend body rounded in the form of a button, lid or the like.

Of the Button or the lid serves as a cover for the holder and can the be adapted to individual or contemporary tastes.

19 shows a plan view of a threaded insert according to 1 to 19 , Based on the plan view according 19 is to recognize that the lead 105 , the blind hole 103 and the internal thread 104 the blind hole 103 are identical in all threaded inserts according to the present threaded insert systems, so that advantageously a uniform appearance when using the corresponding threaded inserts of the profit use systems regardless of the particular configuration with respect to the attachment in a wall 108 . 109 and or 110 given is.

The cross-sectional view according to 20 shows a similar 6 in a wall 108 used threaded insert. In the chamber 106 the threaded insert is in a modification of the use of an adhesive sealant 112 for sealing the hole in the wall 108 used with respect to the threaded insert or the external environment of the threaded insert. The sealing element designed as an annular seal 112 is doing while screwing the threaded insert in the wall 108 over the external thread 101 of the body 100 the threaded insert between the wall 108 and the lead 105 the threaded insert in the chamber 106 compressed under tension, so that a secure seal is given. About one in the internal thread 104 the blind hole 103 screwed in the threaded insert screw 107 in the present case is a holder 1 for an eyelet 8th attached to a soft top textile.

The holder 1 as well as their functionality will be described below in the 21 to 37 illustrated embodiments explained in more detail. Advantageously, an inventive threaded insert for fixing the holder 1 used on a wall, rather than the attitude 1 directly to the wall by means of a screw, as in the 21 to 37 is shown. The embodiments in the 21 to 37 serve to explain the operation of the holder 1 ,

The holder 1 a fastening system according to the invention consists according to the 21 and 21a from a screw 3 and a base pivotable thereon 4 with one out of the opening 8a the eyelets 8th outstanding flat locking nose or tongue 5 and a shoulder formed at the diametrically opposite area 6 , The base 4 is with an elliptical or oval cross-section 2 (please refer 24 ) Mistake. In this case, the eyelet is 8th in a textile body, e.g. As a cover, a tarp or a belt 7 with a very limited elasticity.

The pivot axis 9 the rotatable base 4 with integrally connected with him latch nose or tongue 5 and the shoulder 6 either coincides with the midpoint 10 the ellipse 11 according to 25 together or is on the minor axis 12 the ellipse 11 opposite the center 10 postponed. The main axis of the ellipse 11 is with 13 designated. The two main arches of the ellipse 11 , and the outer one is with 14 and the inner elliptical arc with 15 designated. In the present case, the elliptical arcs exist 14 . 15 from semicircles with the radii Ra and Ri, which are located in the main vertex areas 16 . 17 cross and thus lead to line-shaped main vertices.

According to 21 and 21a will the screw 3 with a thread in a blind hole 18 a wall 19 screwed, which can also be formed by a rail. The head 3a the screw 3 has either a Phillips or a diametrical slit or an internal polygon contour. In the present case, the head 3a the screw 3 with a cross slot 3b Mistake. In addition, the head points 3a the screw 3 between the cross slots 3b a blind hole 3c in which engages for centering the centering of a tool to be described later.

On the bottom 4a of the pedestal 4 is in an annular recess 4b an entropy-elastic disc 20 that under the on the pedestal 4 exerted compressive stress of the screw 3 is set under a spring preload. This spring bias of the entropy-elastic disc 20 is designed to be that 20 on the one hand a sealing function according to 22 for the screw hole 18 in the wall 19 against moisture present and on the other hand, the base 4 and thus the locking nose or tongue 5 and the shoulder 6 under the frictional forces with the wall 19 or holds the rail in any desired position between release position and locking position.

As most vividly 22 shows that engages the pivot axis 9 forming screw 3 with one out of the hole opening 18 outstanding cylindrical part 21 on the coat 22 a cylindrical opening 23 of the pedestal 4 whereas the screw head is 3a with a flange-like extension 3d (please refer 21a ) above the cylindrical opening 23 (please refer 22 ) on a paragraph 24 of the pedestal 4 supported. This allows the tensile stresses of a relatively large area of the base 4 on the cylindrical part 21 below the screw head 3a and from there on short ways over the screw 3 in the wall 19 be transmitted. The flange-like extension 3d of the screw head 3a is kept free of these tensile stresses and serves only to support the base 4 on the wall 19 , These holding forces always parallel or in the pivot axis 9 effective and therefore minimized.

As most vividly 23 can be taken, is the socket 4 in the area below the locking nose or tongue 5 with a sloping plane 25 provided which is inclined to the vertical by an angle a. This inclination by means of the angle a is aligned so that the eyelet 8th under the effect of the tension of the textile or tarpaulin 7 in the direction of the arrow 26 from 23 along this inclined plane 25 in the direction of the arrow 27 against the wall 19 is pulled. This is the eyelet 8th always flat on the wall 19 on (see 31 ). Wind and water forces are difficult to do with the eyelet due to this flat-bottomed attachment 8th Connected textile or tarpaulin 7 or the like. Fluttering under wind forces is thereby also minimized or prevented.

As continues from the 23 to 26 can be removed, is the locking nose or tongue 5 at the top center with a groove 28 and the shoulder 6 in the middle with a notch 29 to approach one more to the 33 to 37 to be described tool 30 Mistake. From the 23 to 26 and from the 27 to 32 results in the elliptical or oval cross-section of the base 4 of two intersecting circles with the radii Ra (outer radius) Ri (inner radius), which is slightly smaller than the inner diameter D of the eyelet 8th is (see 21a . 28 . 30 and 32 ). Due to the inclined plane 25 arises at the foot of the pedestal 4 on the wall 19 a radius Ru that is slightly smaller than the radius Ri and parallel to it (see 25 ).

The base 4 is advantageous with the Rie gel nose or tongue 5 and the shoulder 6 one-piece made of plastic, aluminum or stainless steel. A base made of aluminum 4 with locking nose or tongue 5 and shoulder 6 can be hard-anodized and colored according to your personal taste and time. With a socket 4 with locking nose or tongue 5 and shoulder 6 Plastic is definitely to pay attention to this part 4 . 5 . 6 Made of a UV and salt water resistant material. The screw 3 should be made of seawater resistant stainless steel.

The above became aware of the socket 4 and the locking nose or tongue 5 despite the one-piece manufacture with the shoulder 6 as separate locking elements 4 . 5 designated. The reason is that although the locking nose or tongue 5 the edge of the eyelet 8th engages in the locking position and thus holds, but that the actual locking by the socket 4 takes place, its cross section 2 as an ellipse 11 or oval is formed. Even with a twisting of the locking nose or tongue 5 is the ratio half-axis for an automatic locking 12 to the main axis 13 the ellipse 11 crucial, because of which depends on the release position in the locking position and vice versa changing increase in tension. This tension is undoubtedly also dependent on the extensibility of the respective textile 7 , Tarp or belt. The lower the elasticity of the material in which the eyelet 8th The shorter the main axis can be 13 the ellipse 11 be designed. On the other hand, the larger this elasticity, the greater the length of the main axis 13 the ellipse 11 be sized to overflow the bracket 1 over one of the two main apex areas 16 . 17 to prevent. This should be done by the action of external forces (wind, water) only by using an additional tool 30 be it a screwdriver or the tool to be described 30 according to the 33 to 37 , to be possible.

Based on 27 to 32 Below is the function of the bracket 1 . 3 . 4 . 5 . 6 described in the individual position phases from the release position to the locking position:
The 27 and 28 show the release position of the holder 1 , made in one piece from the pedestal 4 , the locking nose or tongue 5 and the shoulder 6 as well as the screw 3 consists. Maintained is the one-piece design of socket 4 , Locking nose or tongue 5 and shoulder 6 from the screw 3 that in the wall 19 is attached. In the release position is the locking nose or tongue 5 in the in 27 shown position, ie on a vertical wall 19 , pointing up in the drawing plane. For fixing a textile 7 , a tarpaulin, tarpaulin or a belt, with the appropriate eyelets 8th are provided first with each bracket 1 one by one each eyelet assigned to it 8th over the shoulder 6 pulled, just like that 27 identifies. Due to the stretching of the textile 7 it creates a tensile stress in the direction of the arrow 26 that strives to the eyelet 8th through this tension in the textile 7 to move in that direction. To prevent this, must be pressed against the wall pressed eyelet 8th the holder 1 Turn clockwise or counterclockwise. After a 90 ° turn according to the 29 and 30 will increase tension over the eyelet 8th on the pedestal 4 transferred because in this position one of the two main peak areas 16 . 17 the main axis 13 of the pedestal 4 (please refer 23 to 26 ) the lowest eyelet edge (dead center) of the eyelet 8th happens.

In this position, the locking nose or tongue overlaps 5 already partially an edge area of the eyelet 8th , After another rotation of the bracket 1 with the pedestal 4 and the locking nose or tongue 5 by 90 ° the position of the

31 and 32 reached. In this locking position, the locking nose or tongue 5 her the eyelet 8th reached the most comprehensive situation. Furthermore, lies on the lower inner edge of the eyelet 8th the inner elliptical arc 15 with the radius Ri of the ellipse 11 (please refer 25 ) at. In this position the 31 and 32 in turn, the tension within the textile will 7 achieved already when covering the eyelet 8th On the shoulder 6 in the position of 27 and 28 was present. This tension is completely sufficient to the bracket 1 with her pedestal 4 , the locking nose or tongue 5 and the shoulder 6 in the locking position of the 31 and 32 to keep.

Due to the cross-sectional shape of an ellipse 11 or an oval of the socket 4 can this from the locking position of the 31 and 32 in the Loslage of the 27 and 28 only be transferred if the socket 4 can be pivoted to a position of about 90 ° clockwise or counterclockwise. Any swiveling goes immediately with an increase in the tension in the textile 7 accompanied and therefore with an increased pulling force of the eyelet 8th on the pedestal 4 , As a result, of course, the pivoting of the base 4 considerably more difficult. The location of the 27 and 28 can then - and only then - be achieved if after a more than 90 ° -Verschwenkung the bracket 1 with her pedestal 4 the inner edge of the eyelet 8th with one of the two main vertices 16 or 17 happened. This passage is however directly due to the longer main axis 13 opposite the semiaxis 12 with a considerable increase in the tension in the textile 7 connected. This causes this increased tension in the textile 7 an automatic self-backup of the entire holder 1 . 3 . 4 . 5 . 6 against wind and water forces.

If the pivot axis 9 according to the second alternative to the wording of claim 1, not centered 10 the ellipse 11 coincides but on the minor axis 12 the ellipse 11 z. In 28 in the drawing plane downwards, ie opposite to the arrow 26 from 27 is moved, this has in the locking position according to the 31 and 32 a tensile stress in the textile result, which is greater than the tension in the textile in the release position according to the 27 and 28 is. This tension in the locking position will be crucial to the difference between the pivot axis 9 and the center 10 the ellipse 11 marked, which can also be called eccentricity. As a result, the difference Ri - Ru of 25 not reducing the tension. By this displacement of the pivot axis 9 on the minor axis 12 the ellipse 11 the tension can be adjusted individually in the locking position.

An unintentional loosening of the eyelet 8th from the holder 1 under these external forces is not possible. Such a solution is only by applying intentional reaction forces on the holder 1 or their pedestal 4 by means of a tool possible which the increased tension of the textile 7 in the position according to 29 and 30 exceed. This can in turn only with a screwdriver or with the below to the 33 to 37 to be described tool 30 be performed:
This tool 30 is with a centering pin 31 for use in the blind hole 3c of the screw head 3a (please refer 21a ) and also has a footbridge 32 for engagement in the groove 28 as well as an extension 33 for engagement in the notch 29 the shoulder 6 on (see 23 . 25 and 26 ). On the opposite side is the tool 30 with a polygonal bolt 34 provided to the approach of a ratchet or a ring wrench.

According to 33 is used to assemble the extension 33 in the lower part of an eyelet 8th attached and this eyelet against the tension of the textile 7 in the opposite direction of the arrow 26 in the drawing plane of 33 under visual inspection through the eyelet - the recesses (the blind hole 3c , the shoulder notch 29 as well as the tongue groove 28 ) - down to the shoulder 6 the holder 1 pulled and against the wall 19 pressed. This will eventually position according to 34 reached. Will in this position the 34 the tool 30 in one of the two directions of the double arrow 35 pivoted by 180 °, the locking position is in accordance with 35 reached. This locking position corresponds to the already to the 31 and 32 described, whereas the 34 the release according to the 27 and 28 equivalent. Then the tool can 30 in the direction of the arrow 36 from 35 from the holder 1 . 3 . 4 . 5 . 6 pulled out and stored in a readily accessible place at hand.

To the holder 1 again from the locking position according to 35 in the Loslage according to 34 To convert, it requires only a coin or a screwdriver to rotate either clockwise or counterclockwise by 180 ° until the position according to 34 is reached. The lower edge of the eyelet "jumps" 8th under the effect of tension from the shoulder 6 in the direction of the arrow 26 to the top, which automatically sets the release of the textile 7 with the eyelet 8th is reached. After this process, the textile becomes 7 energized.

Due to the bias of the entropy-elastic disc 20 according to 21a the holder remains 1 in the from the 33 and 34 respectively 27 and 28 Removable release position, when the coating of an eyelet 8th On the shoulder 6 is intended or - during the times without cover fabric - the latch nose or tongue 5 the holder 1 should remain aligned until it returns from this to the locking position according to the 31 and 32 is transferred.

The essence of this part of the invention is based in the present case in the automatic self-locking of the holder 1 due to the elliptical cross-section 2 of the pedestal 4 in the form of an ellipse 11 or oval, and the associated Selbstsicherungseffekt means of the main vertex 16 . 17 at the end of the main axis 13 , With each change in position from the locking position according to 31 . 32 and 35 inevitably and automatically increases the tension in the textile 7 associated. From wind and water forces, this increased tension is not - even by chance - overcome.

The further core of this part of the invention is based on the flat design of the locking nose or tongue 5 as well as in the inclined plane 25 below the locking nose or tongue 5 which makes each eyelet 8th under the tension of the textile 7 automatically against the wall 19 is pulled, creating a very intimate and flutter-free attachment of the eyelet 8th with the textile 7 on the wall 19 is guaranteed.
