Description

Tauendbeschlag

The present invention relates to a rope fitting for ropes, ropes or the like.

For many applications, for example in particular in shipping, such as sailing, it is necessary to attach ropes, ropes, lines or the like to an object in a suitable form or to create a handle with which the rope can be pulled securely. For this purpose, the rope is usually provided with a loop at the end. Using this loop, the rope can be placed over a rod or a fastening post, which then holds the rope, or the loop serves as a secure grip for the rope.

In practice, the end of the rope is used to form the loop and returned with the formation of an eye. The returned short end of the rope is then parallel to the long end of the rope over a short area and is firmly connected in the end area of the short end to the long end of the rope, for example by sewing, gluing or the like.

However, there was a need to provide a way to firmly attach a rope to another object, and the rope should also be removable if necessary.

So-called rope fittings can be used for this. The rope fittings contain a rope end securely and firmly connected on the one hand and can on the other hand represent a connection to another object.

In particular, they should be able to hold the rope securely and firmly under load and, for example, make it possible to release the rope again when it is unloaded. Furthermore, the connection with the rope should be easy to establish. According to the invention, this object is achieved by a rope fitting which has a housing with a hollow interior, a first opening being provided on one longitudinal side of the housing, and a second and third opening being arranged in the housing opposite the first opening, the diameters of the first, second and third opening are dimensioned at least for the diameter of a rope, an edge is provided on the inner wall of the housing in the region of the first opening.

Optionally, a pressing means can be provided on the inner wall of the housing on the side on which the short rope end is returned.

In the rope fitting according to the invention, the long end of the rope is inserted through the first opening into the hollow interior of the housing and is led there in the direction of the second opening via an edge which is provided on the inner wall in the region of the first opening. The end of the rope is then returned through the second opening via a deflection and the third opening into the hollow interior of the housing. The short end of the rope comes to rest below the deflection on the long end of the rope.

To fix the short end of the rope to prevent it from slipping out, the short end of the rope is firmly clamped. This can be done by splicing the rope, the end of the rope being intertwined. Other types of fastening can also be used, provided that they ensure a secure fixation of the short end of the rope.

An additional safeguard against the rope slipping out is brought about by the edge which is provided on the inner wall in the region of the first opening and over which the long end of the rope is guided. According to one embodiment, a pressure means can additionally be provided shortly before the cable termination for the secure fixing on the inner wall of the housing on the side on which the short cable end is returned, that is to say the side of the housing that is in contact with the short cable end , which projects in the direction of the opposite housing wall and thus in the direction of the long rope end. The short end of the rope is inserted into the rope fitting in such a way that it lies between the contact pressure and the long end of the rope. In operation, for example by pulling on the rope, the long end of the rope is pressed against the pressing means, so that the pressing means presses into the short end of the rope and fixes it firmly.

With the aid of the edge provided on the inner wall in the region of the first opening, in particular in cooperation with the pressing means, a firm and secure connection of the rope in the rope fitting can be ensured. In addition, the rope can be quickly and easily installed in the rope fitting.

The rope fitting can be configured as required depending on the need and application. For example, the housing can additionally have an eyelet. The housing can be designed in the manner of a karabiner or shackle.

In principle, the rope fitting according to the invention can be produced from any suitable material.

A glass fiber reinforced plastic is preferably used because it has a particularly long service life.

The use of plastic also enables the manufacture of the rope fitting according to the invention by means of casting methods known per se.

The rope fitting according to the invention preferably consists of a glass fiber reinforced polyamide. A preferred embodiment of the invention is described in detail below with reference to the drawings. Show it:

Figure 4 is a view seen from the first opening of the embodiment of Figure 1;

FIG. 5 shows a front view of the embodiment according to FIG. 1;

Figure 6 is another view of the page shown in Figure 1, and

Figure 7 is a view of the embodiment shown in Figure 1 from the side opposite the side shown in Figure 1.

FIG. 1 shows a view of a side face of an embodiment for a rope fitting according to the invention. In this preferred embodiment, the rope fitting is designed as a snap shackle. The part of the housing in which the rope is inserted is used to fasten the rope.

The housing 1 has an opening 2 at one longitudinal end. A second opening 3 and a third opening 4 (here in this figure covered by part of the housing wall and therefore only indicated) are arranged opposite the first opening 2. The rope 5 is inserted with its long end 6 through the first opening 2 into the hollow interior of the housing, and through passed through the second opening 3, the short end 7 being returned via the third opening 4 into the hollow interior of the housing. A deflection 8 is provided between the second opening 3 and the third opening 4, via which the cable is guided.

As shown in Figure 1, part of the housing wall may be missing, for example, as shown here, the part along which the guide of the long end of the rope runs, whereby an additional opening 24 is formed. The opening 24 can extend essentially between the region of the first opening 2 and the second opening 3. The additional opening 24 in the housing enables the precise positioning and guiding of the long and short end of the rope to be monitored. In particular, this configuration enables the long end of the rope to be loosened, for example by pulling it out, so that the short end of the rope can be securely positioned or also released between the long end of the rope 6 and a pressing means.

The diameter of the openings 1, 2 and 3 is dimensioned for the diameter of a rope. It is preferably just large enough to allow a rope diameter to pass through.

As already stated, this special embodiment of the rope fitting according to the invention is a snap shackle. In this case, the housing part arranged above the pigeon mount in FIG. 1 has an eyelet 9. A part of the housing area forming the eyelet 9 is designed as a movable bracket 10, which is connected to the fixed part of the housing, for example via a bracket screw connection 11.

The bracket 10 is closed here with a snap 12. The catch 12 is arranged in the region of the housing in which the second and third openings 3 and 4 are also located. The snapper 12 is connected to the housing, for example, via a snap screw connection 13, the snap screw connection 13 opposite the snapper 12 to the housing on the view side shown in FIG. 1 and opposite this side lying side connects. As a result, the snap screw connection 13 forms an axis which can simultaneously serve as a deflection 8 for the rope.

The yoke screw connection 11 and snap screw connection 13 can be configured as an axle screw connection consisting of an axle screw with an axle sleeve.

FIG. 2 is a view of a narrow side of the embodiment shown in FIG. 1, the narrow side shown being arranged on the left in FIG. 1.

FIG. 3 shows a view of an elevation of the arrangement according to FIG. 1 along the line A-A in FIG. 2.

FIG. 3 shows the guidance of the rope 5 within the housing 1 and the second and third openings 3 and 4 in a particularly clear manner. The rope 5 enters the interior of the housing 1 through the first opening 2 and is there via the edge 14 guided in the direction of the second opening 3.

The edge 14 is provided on the inner wall of the housing 1 in the region of the first opening 2 somewhat above the entry point of the rope, the edge 14 springing back in the direction of the outer wall and having a slope running to the outer wall.

The cable 5 is guided through the second opening 3 along the deflection 8 to the third opening 4 and returns via the third opening 4 into the hollow interior. Here, the returned short end 7 of the rope 5 describes an S-shaped course and comes to lie parallel on the long end 6.

In this embodiment, the short end 7 is guided over a pressing means 15, which is designed to protrude from the inner wall of the housing 1 on the side facing the short end. If, for example, a pull is exerted on the rope 5, the long end 6 of the rope is pressed in the direction of the pressing means 15 and thereby presses the short end 7, which is arranged between the pressing means 15 and the long end 6, against the pressing means 15, whereby the short end is firmly and securely clamped between the pressing means 15 and the long end 6.

As can be seen from FIG. 3, the cable end 16, which extends beyond the pressing means 15 in the direction of the first opening 2, can open into a cavity which is provided between the long end 6 and the region of the housing on the side of the short end 7 is.

In principle, the pressing means 15 can be of any design as long as it ensures that the short end 7 is held securely. The protrusion of the inner wall, which forms the pressing means 15, preferably ends in a tip or tapers off towards a sharp edge. As shown in FIG. 3, the pressing means 15 can be designed as a projection with an inclined side, which forms a kind of pointed tooth that projects into the short end 7 of the cable 5. The pressing means 15 can also be a pointed knob or the like. Due to the pointed design, it is also possible for the pressing means to penetrate the rope, thereby ensuring a particularly firm hold.

According to the invention, the provision of a pressing means 15 represents a possible means for securing the short rope end 7. The pressing means can be firmly connected to the housing 1, as shown in FIG. 3. According to one embodiment, the pressing means 15 can be detachably connected to the housing, so that the rope fitting can or may not be equipped with a pressing means 15 as required.

The present invention thus includes rope fittings with and without pressure means 15 and also those which can be equipped with pressure means 15 as required. FIG. 4 shows the view of the narrow side of the embodiment according to FIG. 1, along which the long end 6 of the rope 5 is guided.

The position of the short end 7 can be clearly seen here that is arranged between the long end 6 and the housing wall. Furthermore, FIG. 4 clearly shows the additional opening 24 in the housing wall along the narrow side, along which the long end 6 of the rope 5 is guided. This opening 24 is arranged essentially on the narrow side of the housing on which the long end 6 of the cable 5 is guided and extends essentially from the region of the first opening 2 to the second opening 3.

FIG. 5 shows the embodiment according to FIG. 1 with the bracket 10 open. The view shows the device according to the invention seen from the narrow side, along which the long end 6 of the rope 5 is guided, although the rope 5 itself is not shown for a better illustration of the configuration.

A series of so-called clamping ribs 17, which are arranged in the region of the deflection 8 (or the snap screw connection 13) and the second opening 3 on the inside of the housing wall, can be clearly seen. These are elongate projections running perpendicular to the housing wall, which additionally secure the rope 5 against unintentional slipping out. The clamping ribs 17 preferably extend from the one housing wall to the opposite housing wall and extend across the surface of the deflection 8. Here, the clamping ribs form a u-shape, so that the opposite housing walls have clamping ribs. The clamping ribs 17 are V-shaped, with the tip pointing upwards. The number of clamping ribs 17 provided can be selected as required. For example, they can cover approximately 50% of the surface of the deflection 8 in the region of the second opening 3. The snap shackle, as shown in the figures as a special embodiment for the rope fitting according to the invention, has a so-called snap 12 as a closure for the bracket.

Depending on the needs and special design of the rope fitting according to the invention, other closures or locking mechanisms can also be provided, such as are usually used for snap shackles or carabiners or the like, for example.

To close the bracket 10 snaps into the snap 12. The snapper 12 shown in the figures has the shape of a substantially U-shaped bracket which encompasses the housing on a narrow side, the ends of the two legs of the Us being fastened on the two side surfaces of the housing. The attachment can be done via the already mentioned snap screw connection 13. This can be designed as an axle screw connection with an axle screw and an axle sleeve, as indicated in the figures.

The design of the locking mechanism is shown in particular in FIGS. 5 and 6. For this purpose, the free end of the bracket has a locking surface 18 for the catch and laterally arranged a recess, the stop recess 19. When closing, the bracket with the stop recesses 19 engages in a corresponding stop groove 20 which is provided in the housing in the position of the catch 12. Here, the locking surface 18 for the catch 12 abuts a corresponding bracket stop surface 21, which is also provided in the housing. The catch 12 is connected to the housing in a resilient manner and thus allows the clip to be snapped into the stop groove 20 and clip stop surface 21 with the appropriately designed free end of the clip.

Due to the spring-elastic connection, the snapper returns to the starting position and holds the bracket firmly in the closed position. For this purpose, a spring element or the like can be provided on one leg end of the snapper. According to a preferred embodiment, the spring element is an integral part of the catch 12, the spring element being firmly connected to the leg end. For this purpose, an area of the leg end on which the spring element is provided can be designed in an arc shape as a spring element, as is shown in FIG. 6 with reference number 22. The integral spring element 22 can also be hinted at in the view according to FIG. 5.

Figure 6 is the view of the embodiment of Figure 1 seen from the opposite side. The arcuately shaped end of a region of the leg of the catch 12 is clearly recognizable here, an integral spring element 22 being formed, the end of which is designed in the form of a hook. The hook-shaped end of the integral spring element 22 engages in a through hole 23 which is provided in the housing and thus effects the fastening and connection of the spring element to the housing.

In addition, a bore 23 can be provided in the front area of the snapper on the outer surface for receiving a snapper loop.

The snapper bucket is used in a manner known per se to release the snapper over a greater distance. Here, for example, the snap loop can be gripped and released with an aid, for example a rod with a hook.

As the example explained above shows, the rope fitting according to the invention can be combined with other functionalities that require a more secure connection with a rope. The rope fitting according to the invention is distinguished in particular by its special arrangement for securing rope ends more securely and thus enables the rope to be connected more securely to other objects or the rope to be handled well.
