Abstract

Safety cable (2) with a belt-shaped core (4) surrounded by a sheath braid (6), characterized in that the core (4) has inextricably entangled elastic strands (8) which are enclosed by a core braid (10).

Description

The The invention relates to a safety rope with one of a sheath braid enclosed, elastic core. Such safety cables are known and are used especially in security applications, in the case of a load bearing (eg fall) to absorb a force, but otherwise in the unloaded state the safety rope only a small length should have.

at known safety or Expanderseilen is the zugelastische Core either as a compact, solid strand of elastomeric material such as For example, rubber or in the form of a bundle or a number of unconnected juxtaposed individual strands of elastomeric material educated. When sewing of an end-face eye there is a risk that individual strands will not can be recorded and pulled out under load. A execution with a single, relatively thick elastomer strand, however, in terms of on elasticity and flexibility disadvantageous.

The The object of the invention is to provide an improved safety or Expanderseil provide, wherein the above Disadvantages no longer occur.

These Task is in a generic safety rope according to the invention thereby solved, that the core is insoluble having entangled elastic strands that of a core braid are enclosed.

These embodiment guaranteed an optimal elasticity and flexibility of the safety rope, while making sure that when sewing a In any case, the elastic core is completely captured without that the danger exists that individual strands could be pulled out.

in the Under the invention, it is irrelevant how the elastic strands the core are intertwined, provided that that not individual strands solved or can be pulled out. Therefore, the core knitted, woven, knitted, crocheted and / or braided strands have, d. H. the core may have single strands, which are formed by working, Weaving, knitting, crocheting and / or lichens insoluble connected to each other.

The strands can as strands, threads, Be formed filaments, fibers or ropes.

The Core network can basically have any number of strands, with 12 or 16 strands are preferred. The sheath braid can also be any Number of strands, with 20, 24 or 32 strands being preferred are.

Conveniently, is provided that at one end or at both ends of the safety rope sewed an eye is. The eye may have a diameter of 1 to 10 times an outer diameter of the safety rope (in the unloaded, tension-free state) is. Further can the eye over a length stitched be that 1 to 10 times an outer diameter (in the unloaded, voltage-free state) of the safety cable corresponds.

Either the safety rope according to the invention as well as the short-circuiting rope can be used in fall arrest systems or restraint systems be used in a variety of forms, for. B. with a fall damper.

The The invention further relates to a short-circuiting rope for a personal protective equipment consisting from a safety rope according to the invention, for attachment on the one hand on a body-connected Belt element and on the other hand on a safety hook.

Prefers is provided that the short-circuiting rope in the relaxed state a length of about 70 cm to about 140 cm. When stretched, the length is usually maximum approx. 2 m.

Further Advantages and features of the invention will become apparent from the following Description of an embodiment, with reference to a drawing, in which

1 explains the structure of the safety cable according to the invention,

2 shows an end-side eye on a safety rope according to the invention, and

3 an application example in the form of a personal protective equipment using the invention shows.

1 explains the structure of a safety or expander rope according to the invention 2 which is a malleable core 4 and a surrounding braid 6 having.

The core 4 in turn consists of inextricably entwined, elastic strands 8th , which can be arranged compact strand-shaped, band-shaped or tubular compact overall, as well as this core strands tubular enclosing core 10 ,

The elastic strands 8th , which may be formed as strands, threads, filaments, fibers or ropes are intangible intertwined and connected by knitting, weaving, knitting, crocheting and / or braiding, so that a single strand 8th can not be pulled out of the totality of strands, as would be the case with a loose bundle of single strands.

2 shows an eye 12 At a free end of a safety rope 2 by sewing along a seam 14 is formed with length L. The eye 12 has a diameter of several rope diameters, in the illustrated case about two to three outer diameter of the safety rope (in the relaxed state).

3 shows an application of the safety cable according to the invention in the form of a short-circuiting cable 16 on the one hand on a body-connected belt element 18 by means of a hook 20 is attached and on the other hand a hook 22 carries, with a fuse to a suitable stationary fuse element is possible. Conveniently, the short-circuiting rope 16 corresponding to one eye at both ends 2 Mistake.
