Passage means for passing pipes, cables and the like through walls

Claim 2

A holding structure for holding and passing conduit means and conductors, especially pipes and electric cables, through a passage in a wall, which includes: at least two holding sections complementary to each other so as together to form a circumferential surface portion fitting into the wall passage through which conduit means and conductors are to be passed, said circumferential surface portion being defined laterally by circumferentially oppositely located elevations on said holding sections, at least one of said holding sections having recess means for receiving conduit means and conductors to be passed through a wall passage, and compressible elastic means interposed between said sections tightly pressed thereby and adapted elastically both to engage and also hold conduit means and conductors in said recess means.

Claim 3

A holding structure according to claim 1, in which said oppositely located elevations have different outer diameters.

Claim 4

A holding structure according to claim 1, in which said elevations are limited to extend over portions only of the circumference of said two holding sections.

Claim 5

A holding structure according to claim 1, in which said holding sections consist specifically of an electrically conductive material.

Claim 6

A holding structure according to claim 1, in which said recess means are so dimensioned that by the said elastic means the conduit means and conductors inserted therein will be firmly held therein irrespective of differing diameters.

Claim 7

A holding structure for holding and passing conduit means and conductors, especially pipes and electric cables, through a passage in a wall, which includes: two pairs of holding sections together forming a frame, two insert members respectively inserted into said pairs of holding members and having their outer circumference together with the adjacent outer circumferential portions of the pairs of holding sections pertaining thereto form a circumferential groove for receiving a wall portion defining a passage, and compressible elastic means interposed between said inserts, said inserts being adapted to receive conduit means and conductors to be passed through a passage in a wall, said compressible elastic means being adapted both to engage conduit means and conductors received in said inserts also to firmly hold the same therein.

Claim 8

A holding structure for holding and passing conduit means and conductors, especially pipes and electric cables, through a passage in a wall, which includes: two pairs of holding sections together forming a frame, two insert members respectively inserted into said pairs of holding members and having their outer circumference together with the adjacent outer circumferential portions of the pairs of holding sections pertaining thereto form a circumferential groove for receiving a wall portion defining a passage, and compressible elastic means interposed between said inserts, said inserts being adapted to receive conduit means and conductors to be passed through a passage in a wall, said compressible elastic means being adapted both to engage conduit means and conductors received in said inserts also to firmly hold the same therein.

Claim 9

A holding structure according to claim 6, in which said inserts consist specifically of an electrically conductive material.
