Claim 5

The anchoring device as defined in claim 2, wherein said tubular sections have cylindrical configurations, and wherein said one cylindrical section overlaps said other cylindrical section over a predetermined length, and thereby sealingly contacts said other cylindrical section over said entire predetermined length.

Claim 6

The anchoring device as defined in claim 2, wherein said first element includes an expansion sleeve member, and an expander member adapted to be drawn into said expansion sleeve member by said second element.

Claim 7

The anchoring device as defined in claim 2, wherein said second elongated portion has an exterior thread, and wherein said adjustable element has a tapped bore which receives and meshes with the thread of said second portion.

Claim 8

The anchoring device as defined in claim 2, wherein said protective sleeve is composed of resilient material and is axially yieldable in response to axial movement of said adjustable element on said second portion.

Claim 9

The anchoring device as defined in claim 1, wherein said protective sleeve is circumferentially complete and is formed of relatively thin-walled corrosion-resistant material.

Claim 10

The anchoring device as defined in claim 2, wherein said tubular end section of said protective sleeve overlaps said tubular extension section of said adjustable element.

Claim 11

The anchoring device as defined in claim 8, wherein said tubular extension section has a tapered leading end formed with a free tip which is received within the interior of said tubular end section, said leading end converging in direction towards said tip so as to facilitate entry of said tubular extension section into said tubular end section.

Claim 12

The anchoring device as defined in claim 2, and further comprising an abutment member mounted on said second portion and engaging the structure in the region of the hole opening, said abutment member being formed with an annular recess which receives in sealing relationship the other tubular end section of said protective sleeve.

Claim 13

The anchoring device as defined in claim 2, and further comprising an abutment member mounted on said second portion so as to be axially spaced from said adjustable element; and wherein said abutment member, said protective sleeve and said adjustable element are all composed of corrosion-resistant material.

Claim 14

The anchoring device as defined in claim 2, wherein said adjustable element engages one side of the object to be mounted; and further comprising a locking element which engages the other side of the object for fixing the object in place at a distance from the structure.

Claim 15

An anchoring device for use in mounting an object to a supporting structure, comprising a first element adapted to be received and anchored in a hole of a structure; a second element having a first portion located in said hole and secured in said first element, and a second elongated portion extending outwardly from said hole; means for positioning an object to be mounted at any of a plurality of distances from the structure, comprising an adjustable element in engagement with the object and being mounted on said second portion for movement in direction of the elongation of the latter; and means for preventing access of corrosion-producing media to said first and second elements at any of said distances, said preventing means comprising a protective sleeve surrounding said second portion intermediate the structure and the object and having a longitudinally-extending tubular end section, and a tubular extension section extending from said adjustable element in direction towards said first element and sealingly engaging said tubular end section, said tubular end section overlapping said tubular extension section so as to provide sealing contact with the latter at any selected distance determined by said adjustable element, and said tubular extension section also having a tapered leading end formed with a free tip which is received within the interior of said tubular end section, said leading end coverging in direction towards said tip so as to facilitate entry of said tubular extension section into said tubular end section.

Claim 16
