Definitions

  • the invention relates to an end connection for a sling, a cord or a rope according to claim 1 and uses thereof according to claims 12-15.
  • Loops are woven from tape fabrics or tape tubes and sewn and manufactured so that an endless loop is created.
  • the disadvantage of these loops is that they must have a large thickening at the connection point or the seam, in order to obtain the required standard strengths.
  • the fabrics must be constructed and woven with very high strengths to compensate for the sewing loss at the seam.
  • a certain width or thickness of the band material paired with the strength of the materials used in the weft and warp must be woven with a certain type of weave in order to achieve the prescribed strengths.
  • the slings should have extremely small cross-sections, the least possible thickening at the seam, and also low weights, especially in the sports, leisure, hobby and occupational safety areas.
  • a loop which is designed as a hose at one end, the other end being pushed and sewn into the hose.
  • FIG. 1 view of an inventive end connection
  • Fig. 6 end connection with a band-like and a rope-like end
  • An end connection 10 is e.g. from a band-like and / or rope-like structure, with two ends 1, 2.
  • One end 1 ends in at least one first end part 3 and the other end 2 in at least one second end part 4.
  • the warp threads are subdivided into three groups with the same number of threads, for example, the end parts 3, 3 'being the same Lead thick. This subdivision does not have to be made uniformly, which then leads to end parts 3, 3 'of uneven thickness. However, since the total number of warp threads in the end parts corresponds to that of the ends 1, 2, the sum of the thicknesses of the end parts corresponds to that of the corresponding end 1, 2.
  • the end parts 3, 4 are now pushed into one another or put together so that they overlap completely or at least partially. In the area of this overlap there is now a connection point 5 at which the end parts are connected. This is done, for example, by sewing, gluing, welding or ultrasound welding, depending on the type of band-like or rope-like structure present.
  • connection point 5 has an abutment 6 at which there is a thickening, which is generally less than 50% compared to a thickening of 100%, which is the same when two ends overlap Thickness arises.
  • the band-like structure is, for example, a band coated with plastic or a band consisting of a plastic or a fabric. Band-like or rope-like structures consist of an extruded, cast or pressed plastic.
  • the two ends 1, 2 do not necessarily have to be symmetrical, neither with regard to the material used, nor with regard to the shape. So one end can consist of a band-like structure and the other of a rope-like structure. Furthermore, the rope-like structure can be a cord or a rope as will be described later.
  • a loop with an end connection according to the invention is connected with fastening means, such as carabiners, hooks, eyelets, plastic parts, aluminum rods and steel pipes, or parts are injected or cast on it, so that the smallest possible diameter or cross section of the end connection is available at these points ,
  • the end connections are woven, knitted, braided, twisted, cast or extruded so that they have wider cross sections at certain points than at the others Have points and are in a loop shape or as a loop.
  • the two ends are then brought together to form an endless loop or a loop and are adjusted in diameter or cross-section so that one end fits within the other end.
  • the sewing, welding or mechanical anchoring of the ends pushed into each other results in a substantially higher connection strength due to the at least doubled area of the ends.
  • End connections are used as full loops in endless form. End connections of this type are used in slings for attaching fall protection systems, ropes, belts, energy absorbers or in slings for attaching to hooks, trees, beams, iron bars and the like.
  • Fig. 2 shows the top view of an end connection with widened end parts.
  • the ends 1, 2 terminate in the end parts 3, 4, which are widened with respect to the width of the ends.
  • the two end parts are shown here without overlap, i.e. before they are pushed into each other, or put together and connected.
  • the significantly widened area at the connection point offers the following advantages: higher strengths and a slight thinning of the end connection with respect to the rest of the product can be achieved. For example, a loop with a cross section of 5 x 5 mm after the widening at the end connection only has a cross section of 10 x 2.5 mm.
  • Fig. 3 shows an end connection with end parts of different lengths.
  • the ends 1, 2 run into the end parts 3, 3 'and into the end parts 4, 4', which are each of different lengths.
  • the end parts 3 ', 4' protrude beyond the end parts 3, 4, which means that when they are placed one against the other, three end parts 3, 4 ', 3' or 4, 3 ', 4' or only two end parts 3 ', 4' are connected are.
  • This can prove to be particularly advantageous if a particularly low thickening is desired.
  • Fig. 4 shows an end connection with welded end parts.
  • the ends 1, 2 run into the end parts 3, 4, which are each of the same length.
  • the end parts 3, 4 are completely pushed into one another and lie against one another in areas 7, T where they are welded together.
  • the advantages of a connection by welding are above all the more rational production but also a higher strength with regard to sewing, for example.
  • the end 2 can also be opposite the end parts of the end 1 with unequal end parts.
  • two or more connection points respectively. There are welds. With multiplication, i.e. with the multiple presence of such connection points, the strength in turn increases.
  • Fig. 5 shows an end connection with sewn end parts.
  • the ends 1, 2 and the end parts 3, 4 correspond to FIG. 4.
  • the connection is established by sewing, which is shown with an indicated seam 8, which generally extends over the entire area of the overlapping end parts. It can also only partially extend or be divided over this area.
  • the sewing represents a very secure connection that can be easily checked for quality at any time (visual inspection).
  • Fig. 6 shows an end connection with a band-like and a rope-like end.
  • the band-like end 1 ends in two end parts 3 of the same thickness.
  • the rope-like end 2 is designed as a cord and is at the same time also an end part with a round, oval or flat cross section 9. This enables a loop to be made more securely, thinner and more flexibly at the end connection.
  • End connections consist of elastic or semi-elastic material, such as synthetic rubber or aramid, Dyneema, PEN (polyester), which can be stretched over a certain distance and then has a high final strength.
  • a loop with such an end connection has, for example, a length of 60 cm and a length of 70-80 cm with a 20% stretch.
  • the length of the sling can be between 5 cm and a maximum of 8 m if suitably adjusted Cross sections vary.
  • these band-like and / or rope-like structures consist of a combination of materials which differ in terms of elasticity, stretching behavior, cut resistance, tear resistance and abrasion resistance, as a result of which optimum tensile strength, abrasion resistance and cut resistance are given with low weight.
  • High-strength fibers made of zylon, Vectran, PBO, Dyneema, Kevlar, aramid, polyester, polyamide and polypropylene are suitable as materials for such end connections and the products made with them, individually or in combination.
  • Embodiment of an end connection for a sling for climbing A band-like end 1 with a narrow cross-section (7 mm band) for hanging a carabiner ends in two end parts 3 of the same thickness, while a band-like end 2 with a wider cross-section (12 mm band) in two end parts 4 also has the same thickness.
  • the end parts are placed against one another, as described in FIG. 5, and are sewn in the overlap area.
  • the end connection consists of Dyneema (70%) and polyamide (30%).
  • the loop with this end connection has a length of 60 cm and a length of 61.2 cm with a 2% elongation.
  • Such end connections and the products made from them are used in general in climbing sports, for example as a climbing sling, or as a sling in occupational safety, but also in sailing, surfing and water sports. These end connections are also used as end connection elements of a cord or a rope.
