Abstract

Corrugated hose-like shell part of a cable routing device for lines, such. Cable, hoses or the like, wherein the line guide means forms a corrugated hose-like sheath (10) and in sections of two opposite corrugated hose-like shell parts (11; 12), in particular of shell parts with different profiles, is composed, characterized in that the shell part (11; 12) on both longitudinal sides has a longitudinally continuous fastening strap (14) which has a toothing with staples (15) which cooperates with a corresponding toothing on an opposite shell part in the manner of a zipper.

Description

The invention relates to a cable routing device for cables such as cables, hoses or the like, which has a first end for attachment to a fixed connection point and a second end for attachment to a relatively movable further connection point. Between their ends, the cable guide device forms an upper run, a movable deflecting bow and a lower run. The deflection arc is curved or pivoted about a deflection axis, preferably with a predetermined radius of curvature, and is typically movable in the plane perpendicular to the deflection axis.

In the operation of a cable routing device, abrasion usually inevitably occurs over time, i. There are small particles due to friction between the lines and / or the components of the cable guide device.

In particular, the invention relates to a further development of the shell parts for a cable routing device of the utility model DE 20 2014 104 458 U1 whose teaching is fully incorporated.

In the aforementioned shell parts, the strength and sealing effect against dust particles of the compound for assembly of the individual shell parts can be improved. It is therefore a corrugated hose-like shell part of a cable guide device, proposed by a corrugated hose-like envelope is formed, which is partially composed of two shell parts, in particular of two shell parts with different profiles.

According to one aspect of the invention, it is proposed that the shell part has on both longitudinal sides a longitudinally continuous fastening strip, which has a toothing, preferably with regularly arranged staples or teeth which cooperate with a corresponding toothing on an opposite shell part in the manner of a zipper , This ensures a firmer connection of the opposite shell parts, which is firmly sealed during operation.

According to a further, independent aspect of the invention it is proposed that a shell part has a longitudinal groove which cooperates positively with a corresponding spring on the other shell part to be connected. Correspondingly, the other shell part, preferably in the region between the toothing and the transition to the corrugated hose-like shell, a spring which cooperates with a corresponding longitudinal groove on the shell part to be connected form-fitting manner. So the seal can be improved.

Further independent as relevant to the invention considered aspects emerge from the dependent claims 2-8.

Further details, advantages and features of both inventions can be taken from the following explanation of preferred embodiments with reference to the accompanying drawings. Hereby show:

1 a schematic diagram of a cable guide device according to the invention in side view;

2 a view of two corrugated hose-like shell parts according to the invention, which to a portion of a cable guide device according to 1 get connected;

3 an enlargement of the lateral fastening straps of the shell parts 2 in connected condition;

4A a front view of a portion of a routing device according to 1 - 3 ;

4B an enlargement according to area IV-B in 4A ;

5 a side view of a portion of a cable guide device according to 1 - 4 with longitudinally staggered shell parts;

6 a section along lines VI-VI in 4A the tight connection of the ends of adjacent shell parts.

In 1 is a schematically shown routing device generally with 10 designated. The cable guide device 10 serves for the protected guidance of cables, hoses or similar lines, which are not shown in detail in the illustrations. Between an upper run and a lower run, the line guide device forms in a known manner an approximately U-shaped deflection bend with a predetermined curvature. In particular, the deflection arc has a predetermined, minimum radius of curvature in order to avoid line breaks and thus ensures that the permissible radii of curvature of the guided lines are not undershot. To build the cable routing device 10 In general, and the particular for the radius of curvature profiling of wave crests and valleys in the main part of corrugated hose-like shell parts 11 . 12 refer We are referring to the doctrine expressly incorporated herein DE 20 2014 104 458 U1 ,

The cable guide device forms a dust-tight corrugated hose-like casing and is partially from each two opposite, corrugated hose-like shell parts 11 ; 12 , with different profiles (see DE 20 2014 104 458 U1 ), composed.

Each shell part 11 ; 12 has on the two long sides a longitudinally continuous fastening strap 14 , The fastening tape 14 each has a toothing with regularly arranged staples 15 or teeth, with a corresponding toothing with staples 15 or teeth on the fastening tape 14 of the opposite shell part in the manner of a zipper.

The staples 15 are on both mounting straps 14 a shell part 11 . 12 identically shaped and arranged. They are arranged with regular distances or free spaces so that they can interlock or interlock like a zipper. The staples 15 have one in 3 apparent a cross section of the at least approximately the shape of an isosceles trapezoid corresponds, wherein the narrow side of each of the shell part to be joined 11 . 12 is turned away, ie that the tapered legs in connected shell part 11 . 12 wedging together, like 3 shows. Released by lateral forces and torsion with respect to the longitudinal direction of the cable guide device 10 is thus effectively prevented. The staples 15 are integral with the fastening straps 14 or the plastic of the shell parts 11 . 12 produced. They are perpendicular to the longitudinal direction of the cable guide device 10 laterally outward, in quasi extensions of the fastening straps 14 ,

4A - 4b show in the area between the teeth with the staples 15 and the transition to the corrugated shell of the shell part 11 . 12 , a longitudinal groove 16 in the fastening tape 14 on one side. The longitudinal groove 16 acts with a corresponding spring 17 on the shell part to be connected together in a form-fitting manner. Each shell part 11 . 12 has on one side in the fastening strap 14 a longitudinal groove 16 and on the other long side in the fastening tape 14 a feather 17 , so symmetrical to the center plane, that identical shell parts 11 or shell parts 12 are also connectable.

6 illustrates the seal of the end-side end portions 18A . 18B , A perpendicular to the longitudinal axis directed and circumferentially continuous sealing projection 19A , with a first tapered and end-thickened cross-section, for example similar in a mushroom head or a piece of stone, engages in an inner, correspondingly extending sealing groove 19B at the other end-side end region 18B , The sealing projection 19A engages in the sealing groove 19B positive and / or non-positive.

In the 3 best recognizable the joint between the fastening straps 14 forms the neutral fiber of the cable guide device 10 ,
