"ENERGY GUIDING CHAIN"
IGUS SPRITZGUSSTEILE FUR DIE INDUSTRIE GMBH, of Spicher Strasse la, 51147 Koln, Germany,
The following specification particularly describes the nature of the invention and the manner in which it is to be performed:-



Energy guiding chain
The invention relates to an energy guiding chain for housing and guiding ducts between a fixed base and a mobile driver.
10 Said chain comprises two parallel plate-link lines consisting of plate-links which are opposite to each other in a cross¬wise direction and connected by means of transverse links. Those plate-links of each plate-link line which are directly adjacent can be pivoted in relation to each other in the di-
15 rection of bending of the chain and the chain forms a deflec¬tion area. At least in an area of the chain adjacent to the driver, the chain links are linked to each other in a trac¬tion-stable manner in several sections by means of at least one element which is substantially non-extendible in the lon-
20 gitudinal direction of the chain and flexible in the direc¬tion of bending of the chain.
Today, energy guiding chains of this kind are largely made of plastic. Polyamides are a preferred plastic. Like other plas-25 tic materials, however, this hygroscopic material has the disadvantage that it has a relatively high coefficient of ex¬pansion in very humid and hot environments.
Energy guiding chains are used in different lengths and sizes 30 under various conditions, such as in very humid and hot rooms or buildings. In long chains, the relatively high additional loads resulting from the ducts housed inside them cause high tensile and thrust stresses when the chain travels. In very hot rooms or buildings with high humidity of up to 100%, such 35 as in composting plants where long chains are used, the change in length due to the tensile stress amounts to up to 8%. In a chain with a length of 100 m, the change in length

adds up to 0.8 m.
As the ducts are connected to both the fixed base and the driver, the change in length of the chain due to tensile 5 stress results in a difference in length between the ducts and the chain, meaning that the ducts are subjected to alter¬nating tension. This tension has a particularly pronounced effect on the inside transverse links in the deflection area of the chain. They are deformed in this context and can even 10 fracture.
When the chain is subject to thrust stress due to the return travel of the driver, the chain tends to rise up in the area of the upper strand, i.e. the upper part of the bent chain, 15 and to overlap, even if only weak upward force components act on it. In this context, the bending stresses that occur in the joint areas of the overlapping chain links are so high that the chain can easily break in this area.
20 An energy guiding chain of the kind specified in the opening paragraph is known from DE 26 09 451 B2. The non-extendible element(s), which is/are flexible in the bending direction of the chain, is/are mounted in the form of a cable or a chain on the underside of the chain links or transverse links, in
25 addition to the articulated joints. They serve to prevent the chain from sagging in the direction opposite the bending di¬rection of the chain. Consequently, no stops are required for this purpose. Instead, the individual chain links of the up¬per strand are firmly pressed together and held in extended
30 position by the non-extendible element provided on the under¬side of the chain links. However, a self-supporting upper strand of this kind is not suitable for relatively long chains with relatively long travel paths.
35 In order to keep the upper strand stretched, the non-extenbibie element miist be mounted on at least every other chain link, as sagging cannot be prevented if the intervals

are any greater. However, mounting the non-extendible element on at least every other chain link makes manufacturing con¬siderably more complex. Mounting the "non-extendible element on every other chain link is also a disadvantage in that the 5 chain cannot relax sufficiently in the deflection area.
In order to keep the upper strand stretched, it is further necessary to pre-tension the non-extendible element in the longitudinal direction of the upper strand. Due to this pre-
10 tensioning, there is a tension difference between the chain and the non-extendible element, particularly during thrust: motion of the upper strand, which causes an upward force com¬ponent. As mentioned above, there is a danger of the chain links of the upper strand rising up when the chain is under
15 thrust, this possibly leading to the fracture of the chain in this area.
If the chain links are made of plastic, tension differences between the chain and the non-extendible element that lead to 20 an upward force component can occur particularly as a result of the thermal expansion of the plastic.
Therefore, the object of the present invention is to design an energy guiding chain in which a change in length due to 25 tensile stress can be avoided with relatively little effort, even at high temperatures and high humidity, and in which the rising of the upper strand under tensile stress is prevented.
This object is solved in an energy guiding chain of the type 30 specified in the opening paragraph in that the chain links, in several sections of at least three links, and the driver are fixed to the non-extendible element(s) in such a way that forces transmitted by the fixation to the chain links act ap¬proximately at the level of the pivoting axes of the chain 35 links and the tension of the element (s) in the longitudinal

direction of the chain is such that it tends towards zero when the chain is thrust by the driver or comes to a halt af¬ter a thrust.
5 The fact that the chain links are mounted on the non-extendible element (s) in sections of at least three chain links, ensures sufficient relaxation of the chain in the de¬flection area. As the forces transmitted to the chain links through the mount act approximately at the level of the piv-10 oting axes of the chain links, tension differences between the chain and the non-extendible element(s) cannot cause an upward force component that could be feared to cause the up¬per strand to rise under thrust against the weight of the chain and the ducts. In this context, the tension of the non-15 extendible element(s) is adjusted in such a way that, when the chain is thrust or comes to a halt after a thrust, only little or no force acts on the articulated joints of the chain links, so that, in particular, the pivoting motion of the chain links in the deflection area is not restricted. 20
Energy guiding chains are already known (DE 94 09 082 Ul, DD 249 742 Al, DE 1 131 480 C1) in which the chain links are connected to one another in a central area by non-extendible elements that are flexible in the bending direction of the 25 chain. Due to their flexibility, the non-extendible elements form articulated connections between the chain links instead of overlapping joint areas. In these chains, however, the chain links are not mounted in sections of at least three chain links, and the driver on the non-extendible element(s). 30 Furthermore, the publications in question do not indicate that the tension of the non-extendible element(s) in the lon¬gitudinal direction of the chain is such that it tends to¬wards zero when the chain is thrust by the driver or comes to a halt after a thrust. 35
In a preferred configuration of the invention, the chain links are mounted on the non-extendible element(s) in sec-

tions corresponding to at least the arc length extending over 180° of the deflection area of the chain.
The forces transmitted through the mount to the chain links 5 preferably act on an area that is approximately at the level of the pivoting axes of the chain links and extends one-quarter of the link height above and below the level of the pivoting axes. An area that extends one-sixth of the link height above and below the pivoting axes is particularly ad-10' vantageous.
The sections in which the chain links are mounted on the non-extendible element(s) can be of identical or different length. Preferably, various lengths are used, where the sec-15 tions become smaller towards the driver due to the fact that the tensile stress of the chain increases towards the driver.
There are preferably between 2 and 5 sections per 50 m chain length.
20
The chain link of the section-wise division that is nearest to the driver is preferably not the directly adjacent chain link, but rather a chain link positioned at a distance of several chain links away that forms the end of the first sec-
25 tion.
The section of the chain adjacent to the driver, in which the non-extendible element(s) is/are arranged, preferably extends over the entire upper strand, the bending area of the chain 30 and into the lower strand when the chain is in a central po¬sition of travel, in which the upper strand and lower strand are of roughly the same length.
The element, or at least one of the elements, is preferably 35 positioned roughly in the middle on the inside of the chain.

At least one element can also be positioned on the outside in the vicinity of the plate-links within the chain.
In particular, the element, or at least one of the elements, 5 can be a steel cable. Steel cables have the advantage that: they have very low extendibility and can be bent without gen¬erating tension. However, any other element that displays these properties can also be used. For example, a metal chain, a horizontally arranged metal strip or a non-10 extendible, flexible belt can also be used.
As the bending of the steel cable, or of any other corre¬sponding element, in the bending area of the chain occurs without tension, the steel cable is positioned in relaxed
15 fashion in this area, meaning that the bending of the chain is not restricted by the steel cable. In the upper strand of the chain, where tensile forces act when the chain is pulled, the steel cable or corresponding element is positioned in taut fashion in the longitudinal direction of the chain,
20 meaning that it can absorb the tensile stress when tensile forces begin to act on the chain.
In a preferred configuration of the invention, the chain links adjacent to those located at the end of individual sec-
25 tions are connected to one another and, of these, the chain link nearest to the driver is connected to driver, in trac¬tion-stable manner by at least one element that is non-extendible in the longitudinal direction of the chain and flexible in the bending direction of the chain.
30
Two taut cables or corresponding elements are preferably po¬sitioned between the chain links adjacent to those located at the end of individual sections and between the one of these chain links nearest to the driver and the driver.
35
The non-extendible element(s) is/are preferably mounted in traction-stable fashion on rails located separately from the

transverse links that are connected to the opposite plate-links of the chain links.
In an expedient practical example of the invention, the ducts 5 guided in the chain are mounted on these rails by means of clamping blocks, the rails also have mounting elements for the ends of steel cables or other corresponding elements.
The rails can have pins on the ends lying in the transverse 10 direction of the chain that act as the link pins of the asso¬ciated chain links. This means that the pins on the rails positively engage two flush openings in the overlapping areas of two adjacent chain links and thus form the pivoting axes of these chain links. This arrangement permits the ducts and 15 separate, non-extendible elements mounted on the rails to be arranged in oscillating fashion about the pivoting axes.
In another, preferred configuration, the ends of the rails lying in the transverse direction of the chain have projec-
20 tions that engage correspondingly designed grooves on the in-sides of the chain links between the joint areas. This ar¬rangement permits the use and replacement of the design ac¬cording to the invention without changing the associated chain links in any other way. The grooves provided in all
25 chain links of a chain series can also be used for mounting other parts between the plate-links.
Practical examples of the invention are described in more de¬tail below based on the drawings. The drawings show the fol-30 lowing:

The overall view in Fig. 1 shows an energy guiding chain 1 for housing and guiding ducts 2 between a fixed base 3 and a
30 mobile driver 4. Said chain comprises two parallel plate-link lines consisting of plate links 5 which are opposite to each other in a cross-wise direction and connected by means of transverse links 7. Those plate-links 5a and 5b of each plate-link line which are directly adjacent can be pivoted in
35 relation to each other in the direction of bending of the chain. The pivoting connection between plate-links 5a and 5b can consist of pins and openings (not shown) arranged in

their overlapping joint area. The pivoting radius is re¬stricted in the bending direction and against the bending di¬rection by interacting stops on plate-links 5a and 5b.
5 As further shown in Fig. 1, non-extendible elements 6 (spe¬cifically 6a, 6b, 6c, 6d, 6e, 6f and 6g) that are flexible in the bending direction of the chain are provided in a section of the chain extending from driver 4, via the upper strand and the bending area, to the lower strand of the chain. These
10 elements connect chain links 7a, 7b, 7c, 7d, 7e, 7f and 7g to one another, these being positioned in sections spaced sev¬eral chain links apart and away from driver 4 in the corre¬sponding area of the chain. Chain link 7a, which is nearest to driver 4, is connected to driver 4 by non-extendible ele-
15 ment 6a.
Non-extendible elements 6a, 6b, 6c, 6d, 6e, 6f and 6g are de¬signed as steel cables. As can be seen in the enlargement in Fig. 1, the steel cable of element 6a is mounted on a mount-
20 ing element 10 of driver 4 by way of a loop 8 that reaches around a bolt 9. Ducts 2 are also mounted on driver 4 by bell-shaped mounting elements 11. Ducts 2 also serve as trac¬tion-stable elements in the chain. Like the steel cables, they are fixed in chain links 7a, 7b, 7c, 7d, 7e, 7f and 7g.
25
As shown in Fig. 1, non-extendible element 6 is positioned in taut fashion in the longitudinal direction of the chain in the horizontal chain links, particularly in the upper strand. This applies to individual elements 6a, 6b, 6c, 6d, 6e, 6f
30 and 6g. Consequently, during the pulling motion of driver 4, non-extendible element 6 absorbs the tensile forces of the chain in the sections of the upper strand, particularly to¬wards driver 4, so that the plastic chain links cannot stretch elastically.


In the bending area of the chain, the linear orientation of non-extendible element 6 in the horizontal plane causes ele¬ment 6 to be arranged in relaxed fashion on the inside of the chain in this area. In Fig. 1, this specifically applies to 5 element 6e. Due to its relaxed arrangement, non-extendible element 6 cannot impair the unrestricted bending of the chain.
The mounting of non-extendible element 6 and ducts 2 on chain 10 links 7a, 7b, 7c, 7d, 7e, 7f and 7g is shown in more detail in Figs. 2 and 3 for a first practical example. A rail 12 made of metal is provided for mounting, the ends of which ex¬tending in the transverse direction of the chain are provided with pins 13, which act as the link pins of the associated 15 chain links. To this end, pins 14 and 15 extend positively through two flush openings in the overlapping joint areas of the adjacent chain links and thus form their pivoting axes.
As shown particularly clearly in Fig. 3, rail 12 has a U-20 shaped profile, where pins 13 are arranged on legs 16 of the U-profile. Legs 16 can be integrally moulded on the horizon¬tal part of rails 12 or mounted on them, e.g. with screws.
Clamping blocks 17a, 17b and 17c are mounted next to legs 16 25 with the help of screws, which firmly clamp ducts 2.
In addition, a mounting element 18 is positioned in the mid¬dle of rail 12 in order to fix the ends of non-extendible element 6, which connects the chain link to the two adjacent 30 chain links of the two adjacent sections or to driver 4. Each connection consists of two steel cables. In order to fix the steel cables, they are connected by a loop 8 to bolts 9 run-

ning in the transverse direction through mounting element 18, as on driver 4 shown in Fig. 1. Radial expansions 19 on the ends of bolts 9 prevent loops 8 from slipping off the side.
5 As shown more precisely in Fig. 2, two bolts 9 are provided on mounting element 18, where the looped ends of the two steel cables extending to one of the nearest chain links ar¬ranged in the sections are mounted on both sides of mounting element 18.
10
The mounting of the steel cables and ducts 2 on a rail de¬scribed above is shown in a second configuration in Figs. 4 and 5. In this practical example, the ends of rails 20 lying in the transverse direction of the chain are provided with
15 projections 22, which engage correspondingly formed grooves 22 on the insides of the chain links between the joint areas. As is shown particularly clearly in Fig. 5, rail 20 is also of U-shaped design, where projections 21 are arranged on the outside of legs 16. The arrangement shown in Figs. 4 and 5 is
20 otherwise the same as that shown in the first practical exam¬ple in Figs. 2 and 3.
While the two practical examples described above show a cen¬tral arrangement of the steel cables on rails 12 and 20, the
25 steel cables in the third practical example shown in Fig. 6 are positioned between ducts 2 in symmetrical fashion in ref¬erence to the centre of the chain. Mounting elements 23 are used for this purpose, which have opposing recesses in the longitudinal direction of the chain, in which the looped ends
30 of the steel cables are mounted on bolts.
The practical example illustrated in Fig. 7 shows a variation of the practical example according to Fig. 6, in which the steel cables are mounted on the outsides of ducts 2 on rail 35 20. The arrangement is otherwise identical to the practical example shown in Fig. 6.

Two further practical examples are shown in Figs. 8 and 9 and 10 and 11. In these practical examples, one or more special ducts 2, which are essentially non-extendible in the longitu¬dinal direction, are used as the non-extendible element(s). 5
The practical example shown in Figs. 8 and 9 corresponds to the arrangement in the practical example shown in Figs. 2 and 3. Ducts 2 are mounted by means of clamping blocks 17a, 17b and 17c on a rail 12, which has pins 13 on the ends lying in 10 the transverse direction of the chain that act as link pins for the two adjacent chain links.
In order to protect ducts 2, they are, in the area in which they are fixed by clamping blocks 17a, 17b and 17c, sur-
15 rounded by collars 24, with which they are inserted into the clamping blocks. Collars 24 protrude on both face ends of the clamping blocks. Collars 24 are designed as sleeves of elas¬tic material that have been slit along their length and are attached to ducts 2 in pre-tensioned fashion by screws on the
20 edges extending along the length of the slit. In this way, ducts 2 cannot shift in clamping blocks 17a, 17b and 17c, even under high tensile stress.
Figure 8 shows the arrangement in a situation in which the 25 chain moves in the thrust direction, i.e. when no tensile stress is acting on the chain links. As shown in Fig. 8, ducts 2 are arranged in relaxed fashion in the chain, without being subject to tensile stress.
30 In the situation shown in Fig. 10, the chain is moving in the tension direction, so that ducts 2 are subjected to a tensile stress due to the elongation of the chain links. They are ar¬ranged in taut fashion in the longitudinal direction of the chain due to the tensile stress.

Figures 10 and 11 show an arrangement that corresponds to the one in the practical examples shown in Figs. 4 and 5. Rails 20, on which ducts 2 are mounted, have projections 21 on the ends lying in the transverse direction of the chain that en-5 gage correspondingly designed grooves 22 on the insides of the chain links between the joint areas. The mounting of ducts 2 on rail 20 is identical to the practical example shown in Figs. 8 and 9.
10 Figure 10 again shows a situation in which the chain moves in the thrust direction (as in Fig. 8), so that ducts 2 are ar¬ranged in relaxed fashion in the chain.
Finally, Fig. 11 shows a situation (as in Fig. 9) in which 15 the chain moves in the tension direction and ducts 2 absorb the tensile forces transmitted to ducts 2 by the elongation of the chain links.
