Abstract

A transit for passing at least one cable ( 11 ) and/or at least one pipe through an opening ( 22 ) in a partition ( 12 ), wherein the transit comprises a first frame ( 19 ), a second frame ( 20 ), wherein the second frame ( 20 ) is arranged with through apertures ( 24 ) and the first frame ( 19 ) is arranged with holes ( 25 ) for receiving threaded fastening screws ( 23 ), so that the first and second frames ( 19, 20 ) can be clamped on opposite sides of the partition ( 12 ) by means of the fastening screws. The transit ( 10 ) further comprises a partition opening liner ( 21 ) for engaging the first frame ( 19 ) and the second frame ( 20 ) and form a radially lined passage extending in an axial direction between the first frame ( 19 ) and the second frame ( 20 ). Disclosed is also the use of such a transit ( 10 ).

First claim

The invention claimed is:

1. A transit for passing at least one cable and/or at least one pipe through an opening in a partition, wherein the transit comprises a first frame, a second frame and fastening screws for fastening the first frame to the second frame, and at least one sealing module for receiving the at least one cable and/or the at least one pipe,
wherein the second frame is arranged with through apertures for the fastening screws and the first frame is arranged with threaded holes for receiving a threaded end of the screws, so that the first and second frames can be clamped on opposite sides of the partition by means of the fastening screws,
wherein the transit further comprises a partition opening liner for engaging the first frame and the second frame and thereby form a radially lined passage extending in an axial direction between the first frame and the second frame,
wherein the first frame comprises an axially extending protrusion for insertion into the partition opening,
wherein the protrusion is arranged with the threaded holes for receiving the fastening screws,
wherein the sealing module is arranged inside the first frame and is formed of two module halves,
wherein each module half has a semi-cylindrical groove, and a compression unit arranged inside the first frame for compressing the sealing module,
wherein the partition opening liner comprises at least a first liner element and a second liner element cooperating with each other to form the partition opening liner, and
wherein one of the liner elements is received telescopically in the other liner element.

2. The transit of claim 1 , wherein the liner elements are formed in a resilient material, wherein the first liner element seals against the first frame, wherein the second liner element seals against the second frame, and wherein the liner elements seal against an adjacent liner element in the axial direction to radially seal the axially extending passage between the first frame and the second frame.

3. The transit of claim 2 , wherein the liner elements are formed with through holes for the fastening screws.

4. The transit of claim 2 wherein the liner elements are formed of rubber or elastomer material.

5. The transit of claim 2 , wherein at least one of the liner elements is formed with a different thickness in the axial direction.

6. The transit of claim 1 , wherein the first liner element is connected to the first frame, and wherein the second liner element is attached to the second frame.

7. The transit of claim 6 , wherein the second liner element is attached to the second frame through the fastening screws.

8. The transit of claim 1 , wherein the axially extending protrusion comprises a flange with the threaded holes for receiving the fastening screws.

9. The transit of claim 1 , wherein at least the first frame forms a closed loop around a through opening.

10. The transit of claim 1 , wherein at least the first frame is provided with a sealing sheet—for engaging the partition around the partition opening.

11. The transit of claim 1 , comprising a number of peelable sheets placed in the semi-cylindrical groove of each module half.
