Abstract

A first element is adapted to be received and anchored in a hole of a structure; and a second element has a first portion located in the hole and secured in the first element, and a second elongated portion which extends outwardly from the hole. An adjustable element is mounted on the second portion for movement in direction of the elongation of the latter and is operative to position an object on the second portion at any of a plurality of distances from the structure. In order to protect the first and second elements from corrosion, an axially yieldable protective sleeve which surrounds the aforementioned second portion intermediate the structure and the object is provided with a tubular end section which sealingly engages a tubular extension section which is provided on the adjustable element. At least one of these sections overlaps the other and thereby provides mutual sealing contact at any of the distances which has been selected for the object.

Dependent claims

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;
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, at least one of said tubular sections overlapping the other of said sections so as to provide sealing contact with the latter at any selected distance determined by said adjustable element;
and 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 for receiving another tubular end section of said protective sleeve in sealing relationship.
