DE2515855C2 - Retaining strap with Velcro fasteners - Google Patents

Description

The invention relates to a universally applicable tether with Velcro fastener Haftmit means for quickly attaching or tying objects, for applying quick bandages, for tying off blood vessels and the like, especially for use in emergencies and disasters.

There are straps with Velcro fastener adhesive known, but have disadvantages that make universal use difficult.

For example, in the German patent application DE-OS 20 35 607 an elastic bandage or Bandage described, which is intended as a vein barrier for medical and surgical purposes.

Such a bandage is not readily suitable for unimpeded use in emergencies, e.g. B. in the Darkness, suitable, especially since insufficient means are provided through which the annoying entanglement of the Wraps in undesired places is prevented with certainty. Obviously the armband is off For reasons of cost, it is also only designed for a load determined by the intended use; she should therefore be available in different sizes for extensive purposes.

According to the German utility model DE-GM 18 38 223 is already a medical congestion known, in the vicinity of the tape end an adhesive of a Velcro fastener and on of the At the end of the more distant part of the tape, a counter-adhesive can be applied.

The same disadvantages apply to this stamina as in the aforementioned case. It is not ensures that such a bandage is of a correspondingly long design even under adverse circumstances can be handled unhindered. In addition, there is also a specific, unchangeable load limit here for a specific application.

The Swiss patent CH-PS 5 23 671 looks at a detachable surface adhesive fastener Hook-and-loop adhesives and counter-adhesives suggest, but also do not provide any means to guarantee all the properties to be expected from a universally usable tether.

The invention therefore has the task of creating a universally usable tether which is suitable in a single embodiment for many tasks of bandaging or girdling and can also be adapted for high loads. It solves this problem in a simple manner in that it forms a tether provided on its entire length and on both sides with Velcro fasteners adhesives in such a way that it consists essentially of a hose formed from looped fabric over its entire length, which is attached to at least one The end is provided with a knitted hook, the hooks of which are on the outside of the hose , and that a replaceable reinforcing band is provided in the hose

A trained in this way tether is to be changed at an appropriate length for quick and solid girding of objects of all kinds suitable The ίο tensile strength can be prepared by optional feed of a reinforcing tape in its cavity within wide limits, is substantially expanded so that the Einsatzmög friendliness for the tether.

In this way, a light, inexpensive basic version of the tether, which is sufficient for use with less stress, can be used for more robust purposes and higher tensile loads after the reinforcement tape has been pulled in. The load on the Velcro fastener adhesive can be kept within permissible limits in any case with a corresponding number of winding layers as a result of the increased frictional forces in the winding. By simply joining several basic designs of the same type, the tether can also be adapted to all winding diameters and the required number of winding layers.

Various details of such a tether are shown in the drawings. It shows in it F i g. 1 the basic version of a tubular tether;

F i g. 2 the tether according to FIG. 1 with inserted reinforcement tape;

F i g. 3 a special version of the tether.
As can be seen from Fig. 1, the basic design consists of a hose 1 made of loop knitted fabric, the loops la essentially cover the entire surface of the hose. The hose can be manufactured using the circular knitting process, but it can also consist of a strip of loop knitted fabric, the longitudinal edges of which are expediently connected to one another by a zigzag seam Xb. At least one end of the hose is attached an adhesive made of knitted hooks, which surrounds it as an endless sleeve 2 with external hooks and is firmly connected to it.

A hose designed in this way can already be used in this basic version (Fig. 1) for bandages, bandages, etc. be used where low or moderate tensile forces occur.

If greater girdle forces are required, a reinforcing band 3 can be drawn into the hose 1 according to FIG. With correspondingly rougher The surface of this reinforcement tape is achieved by frictional adhesion between the reinforcement tape and the inner wall of the hose, the tether reinforced in this way, has considerably greater forces can be transferred without the adhesive of the shell 2 are inadmissibly high stressed.

In order to even with larger winding diameters and a sufficient number of wraps of the Having a sufficiently long belt available for the object can be achieved by lining up the objects in a row several basic designs any extension of the tether to double or multiple b5 of a basic design, namely retaining straps according to FIG. 1 by means of their adhesives 1 and 2 are directly connected to each other. The tether extended in this way can then be used in the same way

can be used like the simple basic version.

With the reinforced variant of the posture belt, the extension can be achieved by stringing together several basic versions take place on a correspondingly longer reinforcing tape 3. In this case, too, arises from The interaction of tensile, holding and frictional forces in the lap creates a more resilient tether unit.

In case of need it is possible to mutual Securing of individual winding layers according to Fig. 3 additional adhesive 4 anywhere on the tether to arrange.

Especially with wider straps, such as those used for securing bandages come, it can be useful to put the loop knitted fabric in area 5 (Fig. 3) immediately before the end attached sheath 2 to be replaced or covered by non-adhesive material. If in this If the length of the non-adhesive material corresponds approximately to twice the length of the shell 2, then the Retaining strap to unroll particularly easily in the end areas without the hooks on adjacent ones Hook areas of the tether. The same effect can also be achieved in that in the above-mentioned Neighboring areas of the sheath 2, the loop knitted fabric by temporary heating or by a hardening bond is rendered ineffective.

The main advantage of the proposed tether over known arrangements is that he not manufactured in several different and more expensive types for different purposes and must be kept ready, but that he is for a Wide range of applications as an inexpensive unit belt

ίο is useful. Hence it is special everywhere there Use where an expensive and cumbersome storage of resources must be avoided. That is especially at rescue stations, emergency aid, land, water and air vehicles (e.g. for Fixing sails, ropes or broken components) or the like of considerable value.

In this context it should be mentioned that the new tether, thanks to its specific construction in the dark regardless of the winding diameter and accidental or deliberate twisting of the Bandage as well as without disabilities due to unreliable entanglement can be handled without any problems. _
