System for dynamically sealing a conduit sleeve through which a pipe or cable extends
First Claim
1. A system for dynamically sealing an opening through which at least one pipe, cable or duct extends via a conduit sleeve extending through the opening and which is fittingly and sealingly fixed to a circumference of the opening or which corresponds to the opening, wherein the system comprises at least an elastically deformable plug which is fittingly and sealingly insertable in the conduit sleeve, the plug having two ends, an outer side and an inner side, each end having dimensions that allow for fitting of that end in the conduit sleeve, the outer side comprising a number of outer ribs having tops spaced apart in a longitudinal direction of the plug for realizing annular contact surfaces between the plug and an inner circumferential wall of the conduit sleeve, the inner side comprising a number of inner ribs having tops spaced apart in the longitudinal direction of the plug for realizing annular contact surfaces between the plug and the at least one pipe, cable or duct, wherein the inner side and/or the outer side is provided with at least one hingeable surface area for facilitating compression of the plug in the longitudinal direction and a transverse movement of at least one of the inner or outer ribs, wherein the system further comprises a blocking element for hindering, when in use an external pressure gradient is present between both ends of the plug, movement of a downstream end of the plug downstream the pressure gradient, and wherein:
- the blocking element and the conduit sleeve comprise together a single piece,an inner diameter of the blocking element is larger than an outer diameter of the pipe, cable or duct, andthe hingeable surface area is provided by two adjacent sloped surfaces of two adjacent ribs that form together a V-shaped groove.

Abstract
A system for dynamically sealing an opening through which at least one pipe, cable or duct extends via a conduit sleeve which is fittingly and sealingly fixed to the circumference of the opening or which corresponds to the opening. The system comprises at least an elastically deformable plug which is fittingly and sealingly insertable in the conduit sleeve. The plug has two ends, an outer side and an inner side. Each end has dimensions that allow for fitting of that end in the conduit sleeve. The outer side comprises a number of outer ribs having tops spaced apart in a longitudinal direction of the plug for realizing annular contact surfaces between the plug and an inner circumferential wall of the conduit sleeve. The inner side comprises a number of inner ribs having tops spaced apart in the longitudinal direction of the plug for realizing annular contact surfaces between the plug and the at least one pipe, cable or duct. The inner side and/or the outer side is provided with at least one hingeable surface area for facilitating compression of the plug in the longitudinal direction and a transverse movement of at least one of the inner or outer ribs.

10. A transit system comprising a conduit sleeve through which at least one pipe, cable or duct extends such that a longitudinal direction of the conduit sleeve and a longitudinal direction of the at least one tube or duct are substantially parallel to each other, wherein the system further comprises at least an elastically deformable plug which is fittingly and sealingly insertable in the conduit sleeve, the plug having two ends, an outer side and an inner side, each end having dimensions that allow for fitting of that end in the conduit sleeve, the outer side comprising a number of outer ribs having tops spaced apart in a longitudinal direction of the plug for realizing annular contact surfaces between the plug and an inner circumferential wall of the conduit sleeve, the inner side comprising a number of inner ribs having tops spaced apart in the longitudinal direction of the plug for realizing annular contact surfaces between the plug and the at least one pipe, cable or duct, wherein the inner side and/or the outer side is provided with at least one hingeable surface area for facilitating compression of the plug in the longitudinal direction and a transverse movement of at least one of the inner or outer ribs, wherein the system further comprises a blocking element for hindering, when in use an external pressure gradient is present between both ends of the plug, movement of a downstream end of the plug downstream the pressure gradient, and wherein:
-
the blocking element and the conduit sleeve comprise together a single piece, an inner diameter of the blocking element is larger than an outer diameter of the pipe, cable or duct, and the hingeable surface area is provided by two adjacent sloped surfaces of two adjacent ribs that form together a V-shaped groove. - View Dependent Claims (11, 12, 13, 14, 15, 33)

16. A system for providing a sealed transit for a situation wherein one or a plurality of cables, pipes or ducts extend through the transit, wherein the system comprises a frame which is sealingly fixed or fixable into or onto an opening, wherein the frame comprises one conduit which is suitable for receiving at least one of the plurality of cables, pipes or ducts and for receiving an elastically deformable plug for sealingly filling space between an inner circumferential wall of the conduit and the at least one of the plurality of cables, pipes or ducts, wherein the system further comprises a blocking element for hindering movement of one end of the plug which is inserted in the conduit, wherein:
-
the blocking element and the frame comprise together a single piece, an inner diameter of the blocking element is larger than an outer diameter of the pipe, cable or duct, and the system is adapted to respond dynamically to an external pressure gradient such that the plug moves in a longitudinal direction relative to the conduit downstream the pressure gradient, expands in a transverse direction in reaction to the external pressure gradient and relaxes after cessation of the external pressure gradient. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
