Abstract
Abstract A mounting support for climbing elements for force fitting into a correspondingly shaped but smaller bore in a wall comprises a hard, strong, yielding plastic sleeve having cylindrical or square inner and outer longitudinal surfaces with serrations in the form of ring-shaped fins which are interrupted to form fish scale sectors with gaps between them. The serrations on the inner surface have oblique slopes running in the direction of insertion of the sleeve into the bore in the wall, while the serrations on the outer surface have oblique slopes running in the other direction. The shanks of the climbing elements are inserted into the sleeves.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
174 words
In combination, a mounting support for insertion into a bore in a wall and a climbing element, said climbing element having a hollow shank portion which is inserted into said mounting support, said mounting support comprising a hard, strong, yielding plastic sleeve having a cylindrical cross-section, said sleeve having uninterrupted inner and outer peripheral surfaces with serrations thereon in the form of annular fins which are interrupted to form fish-scale sectors with gaps between them, said gaps being arranged in staggered relation to each other peripherally, said serrations on the inner surface having oblique slopes running in the direction of insertion of the sleeve into the bore in the wall and the serrations on the outer surface having oblique slopes running in the opposite direction whereby, when the shank of the climbing element is inserted into the sleeve and the sleeve is force fitted into the bore in the wall, said serrations resist pulling away of the climbing element from the wall and said staggered gaps between adjacent fish-scale sectors form a labyrinth seal.
Claim 2
Dependent Claim
174 words
In combination, a mounting support for insertion into a bore in a wall and a climbing element, said climbing element having a hollow shank portion which is inserted into said mounting support, said mounting support comprising a hard, strong, yielding plastic sleeve having a cylindrical cross-section, said sleeve having uninterrupted inner and outer peripheral surfaces with serrations thereon in the form of annular fins which are interrupted to form fish-scale sectors with gaps between them, said gaps being arranged in staggered relation to each other peripherally, said serrations on the inner surface having oblique slopes running in the direction of insertion of the sleeve into the bore in the wall and the serrations on the outer surface having oblique slopes running in the opposite direction whereby, when the shank of the climbing element is inserted into the sleeve and the sleeve is force fitted into the bore in the wall, said serrations resist pulling away of the climbing element from the wall and said staggered gaps between adjacent fish-scale sectors form a labyrinth seal.
Claim 3
Dependent Claim
14 words
A mounting support as claimed in claim 1, wherein said serrations are helically disposed.
Claim 4
Dependent Claim
24 words
A mounting support as claimed in claim 1, wherein a plastic closure plug is provided to close the end of said hollow shank portion.
Claim 5
Dependent Claim
59 words
A mounting support as claimed in claim 3, wherein said plastic closure plug is cylindrical and has an outer surface corresponding to the inner bore of said sleeve which is also cylindrical and wherein said closure plug includes a tube extension smaller in diameter than said plug which smaller diameter corresponds to the inner diameter of said hollow shank.
Claim 6
Dependent Claim
39 words
A mounting support as claimed in claim 4, wherein said outer surface of said closure plug is formed with interrupted ring-shaped fins which slope in the opposite direction as the interior fins on the inner surface of said sleeve.
