e Covering for cable harnesses

8 The invention relates to a casing made of flexible material for

&bgr; Cable harnesses with a longitudinally extending re-openable

10 Closure, which consists of two interlocking profile parts, of

11, one of which is arranged on each longitudinal edge of the casing.

13 Such wrappings are known. They are used to collect and

14 also for the protection of cable harnesses and usually consist of foil-like

is hoses that completely cover the respective cable harness. In order to

To make it easier to attach the hoses, they are equipped with a re-openable

&eegr; closure, which consists of the two profile parts mentioned above

is. Envelopes of this type are described, for example, in DE-PS 29 00 796

ie described. The term "cable harnesses" here stands for a

μ group of elongated objects, for example for

21 Cable harnesses in the narrower sense, wire bundles, hose bundles and the like.

23 When laying cable harnesses and the like, there is often the

24 Need to bend the strands to get them around corners, other parts, etc.

25. Of course, there is the desire to arrange the strands in any

26 direction and also with any bending radius to be able to bend them

27 to adapt to the environment as completely as possible. The previously known

28 Enclosures have the disadvantage that they often limit the bending radius.

29 This is because when bending with a small bending radius, the sheath is compressed at the bending groove and stretched on the opposite side.

31 The thicker the material of the casing, the more disturbing this

32 effect is noticeable. In addition, with strong stretching as well as with

33 more brittle materials there is a risk that the hose will break at the stretched

34 page tears.

36 The invention is based on the object of improving the previously known coverings

37 and to create a casing which, without reducing

38 The bundle effect allows extremely small bending radii in any direction.

&igr; In the limiting case, the bending radii should only be determined by the properties of the

2 cable harness or similar itself may be limited.

4 To solve this problem, we use sheaths for cable harnesses

5, which are made of flexible material and have a

&bgr; longitudinally extending re-openable closure,

7 which consists of two interlocking profile parts, each of which

β one is arranged on each longitudinal edge of the casing. The new one consists

9 in that the profile parts of the closure are directly or above the profile parts

10 assigned carrier strips with the interposition of numerous spaced

11 arranged transverse strips are connected to each other.

13 The cross strips preferably run at right angles to the profile parts

&eegr; or their carriers. However, it is also possible to place the horizontal stripes diagonally

is to be arranged between the profile parts or the beams. In both cases, the

The arrangement is such that the sheathed cable harnesses are only connected to individual

&igr;? are surrounded by banderoles arranged one behind the other, between which

ie free spaces exist. If the cable harness is now bent, the

19 achievable bending radius depends essentially on the properties of the

20 cable harness or other elongated parts in it. In any case

21 there is plenty of space to avoid compression at the bending groove or

22 to prevent excessive stretching on the opposite side. In all

23 As a rule, the proposed casing is arranged so that the profile parts

24 of the closure are located on the stretch side. In view of a

25 desired very small bending radius this may be a hindrance, the

26 Closure also offset from the throat or expansion side,

27 can be arranged, for example, shifted by 90°.

29 It has been shown that it is particularly advantageous if the horizontal stripes

so are foil strips made of the same material as the profile parts

31 or their carrier strips. In this case, the entire casing can simply

32 by punching out a suitably profiled plastic strip

33. However, it is also possible to make the casing from several

34 parts by gluing or welding, a method that will be chosen if, for example, for reasons of strength

stronger locking profiles should be installed.

38 It is further proposed that the transverse strips be made of foil strips with

&igr; embedded reinforcement inserts. The reinforcement inserts

2 can be textile materials, for example fibres, threads or

3 pieces of fabric. It is also possible to use such reinforcing inserts

4 in the carrier strips or the profiles, which is usually

5 will not be necessary since their cross-section is larger anyway.

7 Depending on the intended application of the proposed coating,

&bgr; it may be advantageous if the cross strip wires are made of plastic or metal

β. In this case, particularly high strengths can be achieved and

&iacgr;&ogr; the advantage is achieved at the same time that the cross stripes have a

11 take up a small space.

13 The invention is explained in more detail below with reference to the accompanying drawings

&eegr; explained. They represent:

Fig. 1 is a simplified perspective view of an embodiment of the

&igr;? Envelope with inserted unbent wire bundle;

Fig. 2 shows another embodiment without wire bundle but bent.

20 The casing shown in the drawing is designated as a whole by 1.

21 It has a longitudinally extending, re-openable closure 2

22, which in the example shown consists of two elongated profile parts,

23 which can be inserted into each other and hooked together. Instead of the

24 profile parts can also be used with Velcro fasteners or

25 adhesive closures, provided that an easily re-openable adhesive is used.

27 The profile parts of the closure 2 are connected by numerous

28 transverse stripes 3 are connected to each other, whereby these transverse stripes form the

31 Fig. 1 further shows that the transverse strips 3 are at least

32 approximately at right angles to the closure 2. Instead, however, it is

33 it is also possible to arrange the horizontal stripes diagonally to the closure, whereby

34 also creates a casing that can be easily bent into almost any shape.

36 Fig. 2 shows that the casing is bendable in several directions.

e If even higher requirements are placed on the smallness of the bending radius,
