Description

A TRANSIT SYSTEM AND METHOD FOR RETAINING CABLES TECHNICAL FIELD The present invention relates in general to a transit system for retaining at least one cable in an opening in a construction element. The present invention is also related to a method for retaining at least one cable in an opening in a construction element.

BACKGROUND Cables are arranged in various environments and are lead through different types of construction elements. For passing cables through an opening in a construction element, such as a Wall, a roof, a floor, a partition in a ship, a container, a support structure in a duct or culvert etc. some kind of transit for leading the cables through the opening in the construction element is used. Cables lead through a construction element may have different diameters, Weights and/or be arranged in sloping or even vertical constructions. Depending on these characteristics, it may be more or less challenging to retain cables received in a transit.

A plurality of transits for holding one or more cables is known in the prior art. Known transit devices comprise compressible modules having a through opening for the cable. The through opening may be provided With peelable layers for adapting to the diameter of a cable or a pipe. The cable is clamped in the through opening by a compression arrangement for compressing the module in an axial direction, such as a bolt and nut arrangement, or in a radial direction, such as a Wedge or similar.

Even though known transit devices in the art provide relatively good retaining means there is a need for a more reliable transit system and method for retaining cables in an opening in a construction element.

SUMMARY An object of the present invention is to provide a transit system for leading cables through an opening in a construction element With more efficient and reliable retaining of the cables in the transit and to provide a method for retaining cables in the transit system in an efficient and secure manner.

The present invention is related to a transit system for retaining at least one cable in an opening in a construction element. The transit comprises a compressible body having a first end, a second end, a center axis extending between the first end and the second end and at least one through channel extending between the first end and the second end for receiving a cable. The compressible body further comprises at least one compartment for receiving a clamping element. The compartment is arranged adjacent to the channel and is separated from the channel by a flexible interrnediate wall of the compressible body so that the channel and the compartment cooperate through the flexible interrnediate wall for clamping the cable arranged in the channel when the clamping element is inserted into the compartment. By providing the transit with the at least one through channel for receiving a cable and the at least one compartment, the compartment and the channel being separated by the flexible interrnediate wall of the compressible body, a clamping element can be inserted into the compartment in order to retain the cable arranged in the at least one through channel. The clamping element can be inserted into the compartment to press the cable against the inner surface of the through channel. Thus, the clamping element increases pressure against the cable and friction between the compressible body and the cable and thereby retains the cable in the compressible body in an efficient and reliable manner to counteract pull-down, such as pull-down by the weight of the cable itself Hence, cables can be secured in a sloped orientation or vertical orientation without unintentional displacement thereof.

An advantage of the transit is that depending on size of the cable arranged in the transit, the clamping element introduced in the at least one compartment can be selected so that a clamping force sufficient to retain the cable is applied to the cable through the flexible interrnediate wall by the clamping element. The clamping element of suitable size or diameter can be selected depending on the diameter of the cable to efficiently press the cable against the compressible body. Another advantage is that the transit can be made reusable since a cable and a clamping element arranged in the transit can be removed from the transit and another cable and clamping element can be arranged in the transit instead. The clamping force applied to the cables is easy to adapt by inserting a clamping element having a size sufficient to retain the cable in the transit.

The transit need not be perrnanently altered or adapted to a specific cable. Thus, the transit can be re-usable and can be environmentally friendly.

The at least one clamping element can be an elongated element, such as a rod, pipe or similar, which optionally can be tapered or pointed. The clamping element can be rigid and, e.g. made of metal or a rigid plastic material. Hence, the clamping element can easily be hammered into the compartment to clamp the cable in the through channel.

According to an embodiment, the transit system comprises a compression arrangement for compressing the compressible body. The compression arrangement can comprise a front f1tting abutting the first end of the compressible body and a rear fitting abutting the second end of the compressible body. According to an embodiment, a bolt and nut arrangement is provided to move the front and rear fittings towards each other in order to compress the compressible body. By tightening the bolt and nut arrangement, the front fitting and the rear fitting are pushed towards each other and thereby compress the compressible body in the axial direction. The compression of the compressible body in the axial direction leads to the compressible body expanding radially for fastening in a hole in the construction element or a sleeve arranged in the construction element. Hence, an easy and efficient manner of compressing the compressible body is achieved to further clamp the cable in the transit and at the same time fasten the transit inside an opening.

According to an embodiment, the compressible body comprises a slit extending from a periphery of the compressible body to said channel. The compressible body can be opened at the slit to arrange the cable in the channel.

According to an embodiment, the at least one compartment extends partially around the at least one through channel. Hence, the clamping element of selected size can easily be introduced while efficiently clamping the cable.

According to an embodiment, two of the compartments are arranged adjacent the through channel on opposite sides thereof. By having a compartment on two opposite sides of the through channel or on two opposite sides of each through channel, favorable clamping and retaining of the cable in the through channel can be achieved by inserting clamping elements in both of said compartments.

According to an embodiment, the at least one through channel comprises a center axis extending between the first end and the second end of the compressible body, and Wherein a plane extends along and through the center axis of the compressible body and the center axis of the at least one channel. According to an embodiment, the plurality of compartments are evenly distributed on both sides of the plane. An advantage of the plurality of compartments being evenly distributed on both sides of the plane is that pressure on the cable arranged in the through channel Will be distributed around the cable, so that the cable is pressed by equally by clamping means arranged on both sides of the plane.

According to an embodiment, the plane also represents a symmetry plane for the compartments, so that the compartments arranged on both sides of the plane are mirrored in the plane. Depending on the shape and size of the compartment, the clamping element is guided and held in the compartment in a certain manner. By providing compartments mirrored in the plane, the clamping elements arranged in a compartment on one side of the plane has a corresponding clamping element arranged on the other side of the plane.

According to an embodiment, the compressible body comprises a plurality of through channels for cables, such as three, Wherein said channels are distributed around the center axis. An advantage of providing a plurality of channels is that several cables can be arranged in the transit and lead through an opening in a construction element.

According to an embodiment, the plurality of channels cooperate With each other through a flexible interrnediate partition of the compressible body extending there between. An advantage of the plurality of channels cooperating With each other through the flexible interrnediate partition is that the cables arranged in the channels Will be retained in the transit by applying a clamping force on each other through the flexible interrnediate partition. Thus, the cables arranged in the channels are retained in the transit by each other, as Well as the clamping elements inserted in the compartments.

The present invention is also related to a method for retaining at least one cable in an opening in a construction element, comprising the steps of a) arranging the at least one cable in a through channel of a compressible body of a transit system for leading said cable through the opening in the construction element; and b) inserting a clamping element in a compartment of said compressible body adjacent the through channel, Wherein said channel and said compartment cooperate through a flexible interrnediate Wall and thereby clamping the cable arranged in the channel.

Disclosed is also a method for retaining at least one cable in a transit system for leading the at least one cable through an opening in a construction element. The transit system comprises a compressible body, Wherein the compressible body comprises at least one through channel for receiVing the at least one cable and at least one compartment for receiVing a clamping element. The compartment is arranged adjacent the channel and is separated from the channel by a flexible interrnediate Wall of the compressible body. Said method comprises the steps of: a) arranging the at least one cable in the through channel; b) inserting a clamping element in the compartment and thereby clamping the cable arranged in the channel. The channel and the compartment cooperate through the flexible interrnediate Wall so that the cable arranged in the channel is clamped When a clamping element is inserted into the compartment.

The methods for retaining at least one cable in a transit system results in an efficient and reliable Way of securing and leading the at least one cable through an opening in a construction element.

According to an embodiment, the compressible body comprises a plurality of through channels for receiVing at least one cable, Wherein the methods can comprise, in step a), arranging at least one cable in each through channel.

According to an embodiment, the compressible body comprises a plurality of compartments arranged adjacent the channel and each being separated from the channel by a flexible interrnediate Wall of the compressible body. Step b) of the methods can comprise the step of inserting a clamping element in selected compartments, such as two compartments on opposite sides of a through channel, so that the cable arranged in the channel is clamped from two opposite directions. An advantage of providing the plurality of compartments is that the cable arranged in the through channel Will be retained by several clamping elements arranged around or on opposite sides of the through channel and thus provides additional clamping for the cable.

The method can also comprise the steps of arranging the compressible body in the opening in the construction element and then compress the compressible body by means of the compression arrangement of the transit system.

DETAILED DESCRIPTION OF EMBODIMENTS Embodiments of the present invention will be described more detail below with reference to the accompanying drawings. As used in this description, the terrns “axial” and “radial” and corresponding terrns are in view of a cable going through an opening in a construction element, wherein the cable extends in the axial direction.

Figure 1 is a schematic perspective view of a transit system 10 according to one embodiment. The transit system 10 is used to lead at least one cable 17 (shown in Fig. 4) through an opening in a construction element (not shown) and retain it there. For example, the construction element is a partition, a support structure or other type of construction element. By way of example, the construction element is a partition, such as a wall, a roof, a floor or other type of partition. For example, the construction element is a support structure, e. g. in a duct, culvert, drainage ditch or similar for housing pipes and cables underground as well as above ground and in buildings and other constructions. By way of example, such a duct or culvert holds underground cables 17 or underwater cables 17. By way of example, such cables 17 are for leading gas, oil, electricity or telecommunications. For example, the transit system 10 is arranged for retaining one or more cables 17 running in a slope or in a hanging position, such as in an inclined or vertical orientation. The cables 17 could be arranged in a sloping construction element. More specifically, the present transit system 10 is particularly suitable for leading cables 17 along a slope or a hill. According to one embodiment, the inclination of the slope or the hill is between 1-40°. For example the inclination of the slope or the hill could be around 5-20°.

In Figures 1-6, the transit system 10 for leading cables 17 through an opening in a construction element and retaining them there is illustrated schematically according to one embodiment. The transit system 10 comprises a compressible body 11 having a f1rst end 12 and a second end 13. The compressible body 11 further has a center axis CA extending between the f1rst end 12 and the second end 13. The center axis CA is illustrated in Figures 1, 3 and 5. The compressible body 11 fiarther comprises at least one through channel 14, 15, 16 extending between the f1rst end 12 and the second end 13. The at least one through channel 14, 15, 16 receives a cable 17. In Figures 1, 3-6, the compressible body 11 has three through channels, namely a f1rst through channel 14, a second through channel 15 and a third through channel 16. Each of the through channels 14, 15, 16 is arranged for receiving a single cable 17 or a plurality of cables 1 The compressible body 11 fiarther comprises at least one compartment 18, 19 for receiving a clamping element 20. The at least one compartment 18, 19 and the clamping element 20 are part of the transit system 10 and are shown in Figures 1, 3-6. The at least one compartment 18, 19 and the clamping element 20 help retaining the cable 17 received in one of the through channels 14, 15, Each compartment 18, 19 is arranged adjacent one through channel 14, 15, 16. The compartment 18, 19 is separated from the channel 14, 15, 16 by a flexible interrnediate wall 21 of the compressible body 11. The flexible interrnediate wall 21 is Visible in Figures 1, 3-6. In one example, the flexible interrnediate wall 21 extends between the first end 12 and the second end 13 of the compressible body 11. In one example, the compartment 18, 19 extends between the first end 12 and the second end 13 of the compressible body The through channel 14, 15, 16 and its associated compartment(s) 18, 19 cooperate through the flexible interrnediate wall 21. The through channel 14, 15, 16 and the associated compartment(s) 18, 19 work in conjunction to retain the cable 17 arranged in the through channel 14, 15, 16. According to one example, the clamping element 20 is inserted into one compartment 18, 19 in order to retain the cable 17 arranged in the through channel 14, 15, The transit system 10 further comprises a compression arrangement 25 for compressing the compressible body 11 in the axial direction. The compression arrangement 25 comprises a front fitting 22 and a rear fitting 23 and a bolt and nut arrangement 24. The front fitting 22 abuts the first end 12 of the compressible body 11. The rear fitting 23 abuts the second end 13 of the compressible body 11. The bolt and nut arrangement 24 extends between the front fitting 22 and the rear fitting 23. The bolt extends through a hole in the compressible body 11. In the illustrated embodiment, the transit system 10 comprises three compression arrangements 25, each comprising the front fitting 22, the rear fitting 23 and the bolt and nut arrangement 24. Altematively, the transit system 10 comprises a single front fitting 22 and optionally also a single rear fitting 23, e.g. movable in the axial direction in relation to teach other by a plurality of bolt and nut arrangements 24. By tightening the bolt and nut arrangement 24, the front fitting 22 and the rear fitting 23 are pushed towards each other and thereby compress the compressible body 11 in the axial direction. The compression of the compressible body 11 in the axial direction leads to the compressible body 11 expanding radially for fastening in a hole in the construction element or a sleeve arranged in the construction element. The radial expansion of the compressible body 11, can also lead to the at least one through channel 14, 15, 16 narrowing and thus possibly tightening around the cable 17 received in the channel 14, 15, 16 depending on the diameter of the cable 17. If a plurality of through channels 14, 15, 16 are provided in the compressible body 11, this applies to each of the through channels 14, 15, 16. The radial expansion of the compressible body 11 also leads to each of the through channels 14, 15, 16 narrowing and thus tightening around the cable 17 received in each through channel 14, 15, 16. According to one example, the compressible body 11, e.g. in its entirety, is made of a resilient elastic material, such as rubber, TPE or similar materials. As previously mentioned, Figure 2 illustrates a side view of the transit system 10. More particularly, Figure 2 provides a side view of the compressible body 11, the first end 12 and the second end 13 of the compressible body 11 and the compression arrangement 25. As previously mentioned, Figure 3 provides a top view of the transit system 10. More particularly, Figure 3 provides a front view of the first end 12 of the compressible body 11, the front fitting 22 and the bolt and nut arrangement 24. In Figure 3, the three through channels 14, 15 and 16 extend through the compressible body 11 from the first end 12 to the second end 13. A rear view of the compressible body 11, comprising the second end 13, the rear fitting 23, the bolt and nut arrangement 24 and the three through channels 14, 15 and 16 has not been provided as the front and rear views in the illustrated embodiment of the compressible body 11 would correspond to each other. According to one embodiment, the compressible body 11 is cylindrical as is illustrated in Figures 1-6. For example, the cylindrical compressible body 11 has a length in uncompressed state of 30-300 mm, such as 50-150 mm or around 90 mm. The length of the cylindrical compressible body 11 is the axial uncompressed dimension and is shown in Figure 2. For example, the cylindrical compressible body 11 has a diameter of 50-200 mm, such as 80-160 mm or around 120 mm. The diameter of the compressible body 11 is shown in Figure 3. According to another example, the compressible body 11 is rectangular. The compressible body 11 could have any shape saw fit to be arranged in the opening of the construction element.

The at least one through channel 14 or each of the plurality of through channels 14, 15, 16 has/have a center axis CA”. The compressible body 11 having three through channels 14, 15, 16 is illustrated in Figures 1, 3-6. However, the compressible body 11 may comprise another number of through channels 14, 15, 16 extending between the first end 12 and the second end 13 of the compressible body 11. For example, the compressible body 11 comprises one single through channel, the first through channel 14. For example, the compressible body 11 comprises one to five through channels, such as exactly two, three, four or five through channels. The through channels 14, 15, 16 are arranged circumferentially around the center axis CA of the compressible body 11. For example, the through channels 14, 15, 16 are evenly distributed around the center axis CA of the compressible body As previously mentioned, each through channel 14, 15, 16 holds one cable 17. Thus, each through channel 14, 15, 16 leads one cable 17 through the transit 10. Each through channel 14, 15, 16 secures one cable 17. However, if saw fit, it would be possible for one or more of the through channels 14, 15, 16 to lead more than one cable 17 through the transit 10. For example, at least one through channel or the plurality of through channels 14, 15, 16 could receive two or more cables 17, such as a bundle of cables.

For example, the at least one through channel 14 or the plurality of through channels 14, 15, 16 is/ are formed with a narrow portion and a wide portion, wherein the clamping element 20 is arranged to press the flexible interrnediate wall 21 into the narrow portion while the wide portion accommodates the cable 17. In the illustrated embodiment, each of the three through channels 14, 15, 16 are formed with the narrow portion radially outward and the wide portion in a more central position of the compressible body. Altematively, the at least one through channel 14 or the plurality of through channels 14, 15, 16 is/are essentially cylindrical as is illustrated in Figures 1, 3- ll 6. Altematively, the at least one through channel 14 or the plurality of through channels 14, 15, 16 is/are essentially rectangular. By Way of example, the plurality of through channels 14, 15, 16 can have different shapes and sizes. According to one embodiment, the through channels 14, 15, 16 are configured for receiving a cable 17 having a diameter of at least 5 to 70 mm, such as 15 to 60 mm or 30-60 mm. For example, the through channels 14, 15, 16 are configured for receiving cables 17 having diameters differing up to 20 mm, such as 15 mm or around 10 mm. According to one embodiment, the through channels 14, 15, 16 are essentially cylindrical, at least When the flexible interrnediate Wall 21 has been pressed out, Wherein the through channels 14, 15, 16 have a diameter of 5 to 70 mm, such as 15 to 60 mm or around 30-60 mm. In Figures 1, 3-6, the first, the second and the third through channels 14, 15, 16 are of the same size and shape. In Figure 4, a cable 17 is shown to be received in the third through channel 16. Each of the through channels, the first through channel 14, the second through channel 15 and the third through channel 16, receives a cable 17. The cables 17 are retained in the through channels 14, 15, 16. One cable 17 is fixed in the first through channel 14, one cable 17 is fixed in second through channel 15 and one cable 17 is fixed on the third through channel 16. The cables 17 are fixed by means of the clamping elements 20 and the compression arrangement 25. By compression of the compressible body 11 in the axial direction, the compressible body 11 expands radially. The radial expansion of the compressible body 11, leads to the at least one through channel 14, 15, 16 narroWing and thus tightening around the cable 17 received in the at least one through channel 14, 1 5, 1 6. With reference to the transit 10 of Figures 1, 3-6, each through channel 14, 15, 16 is arranged With the adjacent first compartment 18 and the adjacent second compartment 19. The first compartment 18 and the second compartment 19 are arranged partly around the through channel 14, 15, so that a first compartment 18 and a second compartment 19 are arranged partly around the first through channel 14, a first compartment 18 and a second compartment 19 are arranged partly around the second through channel 15 and a first compartment 18 and a second compartment 19 are arranged partly around the third through channelTo ensure a retaining fit between the transit 10 and the one or more cables 17 arranged therein, a clamping element 20 is inserted in the compartment 18, 19 adjacent the through channel 14, 15, 16. For example, a clamping element 20 with suitable thickness, such as diameter, is inserted in the first compartment 18 arranged adjacent the first through channel 14 and/or another clamping element 20 is inserted in the second compartment 19 arranged adjacent the first through channel 14. For example, clamping elements 20 are inserted in all of the first and second compartments 18, 19. Thereafter, the compression arrangement 25 described above may be tightened. Thus, the cable(s) 17 is/ are retained in the through channels 14, 15, 16 by means of the clamping element(s) 20 received in the compartment(s) 18, 19 of the compressible body 11 and/or the compression arrangement According to one example, the cables 17 has a diameter that essentially corresponds to the diameter of the through channel 14, 15, 16 in which it is received so that a tight fit between the cable 17 and the through channel is obtained. In such a case, it may not be necessary to provide a clamping element 20 in the compartments 18, 19 in connection with the through channel 14, 15, When the cable 17 is arranged in the through channel 14, 15, 16, the flexible interrnediate wall 21 shapes around the cable 17. Since the interrnediate wall 21 is flexible and bendable, the interrnediate wall 21 will conforrn the shape of the cable 17 that is received in the through channel 14, 15, 16. By way of example, the flexible interrnediate wall 21 is made of an elastic material, such as rubber.

The clamping element 20 is received in the compartment 18, 19 to press the cable 17 against the inner surface of the through channel 14, 15, 16. Thus, the clamping element 20 retains the cable 17 in the compressible body 11. The clamping element 20 is arranged to be forced into the compartment 18, 19 and thereby fasten the cable 17 in the through channel 14, 15, 16. For example, the clamping element 20 is an elongated element to be introduced into the compartment 18, 19 and there extend axially between the first end 12 and the second end 13 of the compressible body 11. By way of example and as is shown in Figures 1-5, the clamping element 20 is a rod. The clamping element 20 could also be a pipe. For example, the clamping element 20 is formed with a constant diameter or is tapered. The clamping element 20 is made of a rigid material,such as metal or a rigid polymer material. The clamping element 20 should be able to be hammered into a compartment 18, 19 when a cable 17 is arranged in the corresponding through channel 14, 15, 16. By way of example, the clamping element 20 is made of steel. The clamping elements 20 are i11serted to increase the friction between the compressible body 11 and the cables In Figure 5 clamping elements 20 to be inserted in the compressible body 11 are illustrated. The transit system 10 comprises clamping elements 20 of different diameters, e.g. sets in different diameters, such as at least two or at least three different diameters. In Figure 5, two different types of clamping elements 20 are illustrated, a first clamping element 20a with a first diameter and a second clamping element 20b with a second diameter. Clamping elements 20 with two diameters are provided by way of example and it should be understood that the clamping elements 20 with other diameters are suitable as well. The clamping elements 20 having two different diameters can also be seen in Figures 1, 3, 6. Clamping elements 20 of different sizes may be inserted into the compartments 18, 19 of the compressible body 11 to increase the friction between the compressible body 11 and cables 17 of different sizes. For example, the clamping elements 20 have diameters of 1-20 mm, such as 2 to 10 mm. For example, the first clamping element 20a has a diameter of 4-10 mm, such as 5 mm and the second clamping element 20b has a diameter of 1-4 mm, such as 3 mm.

As can be seen in Figures 1, 3-6, the three through channels 14, 15, 16 in the illustrated embodiment are distributed around the center axis CA. The three through channels 14, 15, 16 are separated from each other through a flexible interrnediate partition 26 of the compressible body 11 extending there between. The cables 17 arranged in the channels 14, 15, 16 are retained in the transit 10 by each other, as well as the clamping elements 20 inserted in the compartments 18, 19, since the cables 17 apply a clamping force on each other through the flexible interrnediate partition 26. The flexible interrnediate partition 26 is flexible and bendable. The interrnediate partition 26 will conforrn the shape of the cables 17 received in the through channels 14, 15, 16. By way of example, the flexible interrnediate partition 26 is made of an elastic material, such as rubber.The flexible interrnediate partition 26 has three substantially straight wall portions 26a-c, e. g. in the shape of a three-pointed star extending between the through channels 14, 15, 16. Hence, as can be seen in Figure 3, the flexible interrnediate partition 26 comprises a first wall portion 26a, a second wall portion 26b and a third wall portion 26c. A first end of each wall portion 26a, 26b 26c are linked together and a second thereof extends radially, e.g. so that the wall portions 26a, 26b 26c are angularly displaced in relation to each other by 120°. The second end of the first wall portion 26a, the second wall portion 26b and the third wall portion 26c are linked with flexible interrnediate walls 21 of the first compartment 18 and the second compartment 19 of the first through channel 14, the second through channel 15 and the third through channel 16, such that the second end of the first wall portion 26a is linked to the first compartment 18 of the first through channel 14 and the second compartment 19 of the third through channel 16. The second end of the second wall portion 26b is linked to the second compartment 19 of the first through channel 14 and the first compartment 18 of the second through channel 15.

This is illustrated in Figure As illustrated in Figures 3-4, the compressible body 11 may further comprise a slit 27 extending in a radial direction between one of the through channels 14, 15, 16 and the periphery of the compressible body 11. The slit 27, which could also be called a split, can be pulled apart to open the compressible body 11 to arrange a cable 17 in the through channel 14, 15, 16. For example, the slit 27 may extend along the entire length of the compressible body 11. Thus, the slit 27 extends from the first end 12 to the second end 13 of the compressible body 11. Altematively, the compressible body comprises a plurality of slits 27 such that a slit 27 extends between each through channel 14, 15, 16 and the periphery of the compressible body 11. Thus, a cable 17 can be arranged in each through channel 14, 15, 16 through said slits In the illustrated embodiment, the flexible interrnediate partition 26 comprises slits 28 so that cables can be arranged in all through channels 14, 15, 16 of the compressible body 11. In Figure 3 and 4, the slit 28 extends from the center axis CA in a radial direction toward the first through channel 14, the second through channeland the third through channel 16. Thus, the compressible body 11 can be opened through the slits 27, 28 for access to all through channels. A cable 17 introduced into one of the through channels 15 through the slit 27 is provided access to the other through channels 14, 16 through the slits 28 in the flexible interrnediate partition As previously mentioned, each through channel 14, 15, 16 could have one or a plurality of associated compartments 18, 19. For example, each through channel 14, 15, 16 has one compartment 18, 19 arranged adjacent to the through channel 14, 15, 16. The compartment 18, 19 is separated from the channel 14, 15, 16 by the flexible interrnediate wall 21 of the compressible body 11 extending between the through channel 14, 15, 16 and the compartment 18, 19. For example, each through channel 14, 15, 16 has two compartments 18, 19 arranged adjacent to the through channel 14, 15, 16 as is illustrated in Figures 1-5 and previously described. The two compartments 18, 19 are each separated from the channel 14, 15, 16 by flexible interrnediate walls 21 of the compressible body 11 extending between the through channel 14, 15, 16 and the compartments 18, 19. Altematively, each through channel 14, 15, 16 has three or more compartments 18, 19 arranged adjacent to the through channel 14, 15, 16. The compartments 18, 19 are each separated from the channel 14, 15, 16 by flexible interrnediate walls 21 of the compressible body 11 extending between the through channel 14, 15, 16 and the compartments 18, 19. The at least one compartment 18, 19 or the plurality of compartments 18, 19 extends/extend partially around the through channel 14, 15, 16 to which it is linked by the flexible interrnediate wall 21 extending there between.

A plane (not illustrated) extends between the center axis CA of the compressible body 11 and the center axis CA” of the at least one channel 14, 15, 16. According to one embodiment, the compartments 18, 19 are arranged on both sides of said plane. According to one embodiment, the plane represent an axis of symmetry for the plurality of compartments 18, 19. Hence, the compartments 18, 19 are mirrored in the plane and are arranged on both sides of the plane. Thus, the compartments 18, 19 are symmetrically arranged about the plane.

According to another example, the plurality of compartments 18, 19 are distributed around the channel 14, 15, 16 so that each of the plurality of compartmentsis angularly displaced about the center axis CA” of the channel 14, 15, 16 in relation to the other compartments 14, 15, Figure 7 is a flow chart illustrating a method 100 of arranging at least one cable 17 or a plurality of cables 17 in the transit system 10 for leading the at least one cable 17 or a plurality of cables 17 through an opening in the construction element such as the one described by Way of example above. The method 100 comprises the step of arranging 102 the at least one cable 17 in the through channel 14, 15, 16 if the compressible body 11 of the transit 10 comprises one through channel 14.

Thus, the method 100 comprises the step of arranging 102 a cable 17 in each through channel 17. Thus, the transit system 10 is suitable for retaining three cables 17 in the compressible body 11 and leading the three cables through an opening in a construction element.

As previously described, the transit system 10 comprises the compressible body 11, Wherein the compressible body 11 comprises the at least one through channel 14, 15, 16 or the plurality of through channels 14, 15, 16 for receiving the at least one cable 17 each. The compressible body 11 fiarther comprises the at least one compartment 18, 19 or the plurality of compartments 18, 19 for receiving a clamping element 20 each.

If the compressible body 11 comprises one compartment 18, 19, the one compartment 18, 19 is arranged adjacent said channel 14, 15, 16 and is separated from said channel 14, 15, 16 by a flexible interrnediate Wall 21 of the compressible body 11. The method 100 further comprises the steps of inserting 104 the clamping element 20 in the at least one compartment 18, 19 so that said channel 14, 15, 16 and said compartment 18, 19 cooperate through the flexible interrnediate Wall 21 for clamping the cable 17 arranged in the channel 14, 15,If the compressible body 11 comprises a plurality of compartments 18, 19, the plurality of compartments 18, 19 are arranged adjacent said channel 14, 15, 16 and are each separated from said channel 14, 15, 16 by flexible interrnediate walls 21 of the compressible body 11. The method 100 comprises the steps of inserting 104 a clamping element 20 in each compartment 18, 19 so that said channel 14, 15, 16 and said compartments 18, 19 cooperate through the flexible interrnediate walls 21 for clamping the cable 17 arranged in the channel 14, 15, 16. The method 100 comprise the steps of inserting 104 the clamping element 20 in each compartment 18, 19 so that said channel 14, 15, 16 and said compartments 18, 19 cooperate through the flexible interrnediate walls 21 for clamping the cable 17 arranged in the channel 14, 15, By example, Figures 1-6 show that each through channel 14, 15, 16 comprises two compartments 18, 19 arranged circumferentially around each through channel 14, 15, 16. Thus, the method 100 comprises the step of arranging 104 a clamping element 20 in each of the two compartments 18, 19 of each through channel 14, 15, 16. Thus, a total of six clamping elements 20 can be arranged in the compressible body The method 100 further comprises the step of compressing 106 the compressible body 11 in an axial direction by a compression arrangement 25 of the transit system 10 so that the compressible body 11 expands radially. This step can be performed before or after step 102 and/or step 104 and/or in between step 102 and 104. The radial expansion of the compressible body 11, leads to the at least one through channel or the plurality of channels 14, 15, 16 narrowing and thus tightening around the cable 17 received in the at least one channel or the plurality of channels 14, 15, 16. Meanwhile, the compartments 18, 19 are also narrowed by this expansion. Thus, the grip around a clamping element 20 is tightened thus applying additional pressure on the through channels 14, 15, 16 and the cables 17 arranged therein. The expansion of the compressible body 11 also leads to the compressible body 11 being pressed against the opening in the construction element. Thus, retaining the transit system 10 in the construction element.
