Definitions

  • the invention relates to a round sling for use on carrying means with a first protective tube partially enclosing the round sling to form a sling.
  • Round slings and a sling made from them have been known for a long time, for example from the EP 32749 A1 or the WO 03/048023 A1 , which discloses the features of the preamble of claim 1.
  • All individual elements of the round sling, which form the strap are known to be irreversibly connected to one another, i.e. sewn.
  • openable protective tubes are also known, for example from the US 2015/0267347 A1 which have an openable protective tube for a rope or the JP H07 41279 A for a belt sling.
  • the object of the invention is to further improve a round sling in the form of a sling.
  • a round sling according to the invention for use on load-bearing means has the following features.
  • the round sling has a first protective tube that partially surrounds it to form a sling, whereby end areas of the round sling are not enclosed by the first protective tube and the end areas therefore form loops.
  • At least one enclosing band is to be attached to the first protective tube at each end in the direction of the loops as Loop reinforcement is arranged, which rests on an outer surface of the respective loop of the round sling and is thus placed around the loop.
  • the at least one enclosing band is preferably not separately connected to the loop by sewing, gluing or similar.
  • connection of the at least one enclosing band to the first protective tube is carried out, for example, by sewing. All other suitable connection forms are also within the scope of the invention, such as all force-fitting and/or form-fitting or material-fitting connection types.
  • an openable second protective tube is arranged on each of the loops, which encloses the encircling band and thus an area of the round sling on which a tag can be arranged and completely or at least partially covers the loop and the encircling band, i.e. axially covers it in the longitudinal direction.
  • a covering is necessary so that the respective encircling band is reliably locked in place by the second protective tube.
  • the second protective tube thus ensures that the encircling band is fixed as a loop reinforcement.
  • a closure region of the respective second protective tube is advantageously located outside a contact surface with the support means in order to reduce an impairment of the connection region and thus an impairment of the locking of the respective second protective tube due to mechanical stress by the support means.
  • the inventive arrangement and the interaction of the individual components described above further improve the load-bearing capacity of the round sling.
  • the multi-layer structure also improves the durability of the round sling. It also ensures that individual elements of the round sling in the form of the strap can be replaced.
  • an openable third protective tube is arranged above the first protective tube and essentially encloses the first protective tube. This results in improved protection of the round sling in the load-bearing area if, for example, the round sling is used to transport coils, such as steel coils.
  • a Velcro fastener for example, is provided as a means of connecting the openable second and third protective tubes.
  • the first protective tube can be connected to the round sling, as is known, preferably reversibly, by being loosely pushed onto the round sling or, although this is not preferably the case, irreversibly connected to the round sling by being loosely pushed onto the round sling as part of the formation of the strap and then an area of the first protective tube between the two strands of the round sling is at least partially connected, i.e. sewn.
  • the first protective tube then has two chambers. Nevertheless, it is generally arranged so that it can be moved on the round sling and all connections are preferably reversible in order to ensure easy changeability.
  • An improved locking of the first or the first and the third protective tube can also be achieved by means of at least one closure, wherein the at least one closure is arranged at the respective ends of the first protective tube or at the respective ends of the first and the third protective tube and preferably, but not necessarily, passes through the loop interior when it is closed.
  • the at least one closure can be firmly connected to the first and/or the third protective tube or can be a separate element which can penetrate or clamp the first protective tube and/or the third protective tube for locking purposes.
  • the at least one closure can advantageously be closed reversibly, for example by means of a clamping device. Clamp locks, buckles or similar devices can be considered.
  • the at least one closure is a section of tape.
  • a round sling 1 according to the invention for use on load-bearing means has a first protective tube 2 partially enclosing it to form a sling, wherein end regions of the round sling 1 are not enclosed by the first protective tube 2 and the end regions therefore form loops 4, 4' .
  • a surrounding band 5, 5' is arranged as a loop reinforcement.
  • the respective surrounding band 5, 5' rests loosely on an outer surface 6 of the respective loop 4, 4' of the round sling 1 and is thus placed around the loop without further fastening.
  • the respective surrounding band 5, 5' is connected to the first protective tube 2 at the ends 3, 3' according to the Fig. 1 and 2 sewn twice at a distance so that the respective enclosing band 5, 5' also forms a loop.
  • an openable second protective tube 7, 7' is arranged on the respective loops 4, 4' , which encloses an area of the round sling 1 on which a suspension element can be arranged and almost completely covers the respective enclosing band 5, 5' and thus locks it in place.
  • a closure area of the second protective tube 7, 7' is located outside of a contact surface with the suspension element when this is functionally connected to the round sling 1. The closure area is therefore not exposed to any direct stress from the suspension element.
  • An openable third protective tube 8 is arranged above the first protective tube 2 , which essentially encloses the first protective tube 2 , i.e. covers it in its longitudinal direction.
  • a Velcro fastener is provided as a connecting means for the openable second and third protective tubes 7, 7' and 8 .
  • the closure 9 is arranged at the respective ends 3, 3' of the first protective tube 2 and the third protective tube 8.
  • the closure 9 passes through the loop interior 10 when it is functionally closed. This prevents it from being pulled off the round sling 1.
  • the closure 9 is formed by two detachable straps arranged at the ends 3, 3', each with a belt clamp, with the closure 9 penetrating the first protective tube 2 and the third protective tube 8 at slots provided for this purpose.
