Claim 8

A device as defined in claim 5, wherein said second sleeve member has a shoulder located between said first and said second part of said bore and extending substantially in said second direction, said rear end portion of said first sleeve member having a rear end face facing said object and abutting said shoulder so as to permit turning of said first and second sleeve member relative to one another.

Claim 9

A device as defined in claim 2, wherein said second sleeve member has a front end section facing said structure and a rear end section spaced from said front end section in said first direction, said rear end section of said second sleeve member being provided with said abutting section.

Claim 10

A device as defined in claim 8, wherein said abutting section is a flange portion having a supporting surface extending in a second direction substantially transverse to said first direction and adapted to abut against said object to be mounted, said supporting surface being in said second direction of a dimension exceeding the cross-section of said rear end section of said second sleeve member.

Claim 11

A device as defined in claim 8, wherein said flange portion is of one piece with said second sleeve member.

Claim 12

A mounting device in combination with a masonry structure and the like, comprising, an expandable member received and anchored in a hole of said structure; an expander member for expanding at least a leading end of said expandable member; a shaft member having a first portion located in said hole and connected with said expander member, and a second portion outwardly projecting from said hole in a first direction from said structure towards an object being mounted and carrying said object at a distance from said structure; a ring-shaped member located between said expandable member and said shaft member; and a sleeve-shaped element of a corrosion-resistant material including a first sleeve member, a second sleeve member and a flange portion, said first sleeve member enclosing said first portion of said shaft member and one section of said second portion thereof adjacent said first portion over a length corresponding to a part of said distance, said first sleeve member having a front end portion located in said hole and a rear end portion spaced from said front end portion in said first direction and having a rear end face facing said object, said ring-shaped member being fixedly connected to said front end portion of said first sleeve member, said second sleeve member enclosing another section of said second portion of said shaft member over a length corresponding to the remainder of said distance, said second sleeve member having a front end section facing said structure and a rear end section spaced from said front end section in said first direction, said second sleeve member being provided with a central bore having a first part adjacent said rear end section and a second part adjacent said front end section, said second part of said central bore being of a dimension in a second direction transverse to said first direction exceeding the respective dimension of said first part of said bore and corresponding to the outer dimension of said rear end portion of said first sleeve member, said second sleeve member having a shoulder located between said first and said second part of said central bore and extending substantially in said second direction, said rear end portion of said first sleeve member being received in said second part of said central bore of said second sleeve member with a friction fit and said rear end of said rear end portion of said first sleeve member abutting said shoulder of said second sleeve member so as to permit turning of said first and second sleeve members relative to one another, said flange portion being connected to said rear end section of said second sleeve member and having a surface extending in said second direction and abutting against said object to keep it at said distance from said structure, said abutting surface being in said second direction of a dimension exceeding the cross-section of said rear end section of said second sleeve member.

Claim 13

A mounting device in combination with a masonry structure and the like, comprising, an expandable member received and anchored in a hole of said structure; an expander member for expanding at least a leading end of said expandable member; a shaft member having a first portion located in said hole and connected with said expander member, and a second portion outwardly projecting from said hole in a first direction from said structure towards an object being mounted and carrying said object at a distance from said structure; a ring-shaped member located between said expandable member and said shaft member; and a sleeve-shaped element of a corrosion-resistant material including a first sleeve member, a second sleeve member and a flange portion, said first sleeve member enclosing said first portion of said shaft member and one section of said second portion thereof adjacent said first portion over a length corresponding to a part of said distance, said first sleeve member having a front end portion located in said hole and a rear end portion spaced from said front end portion in said first direction and having a rear end face facing said object, said ring-shaped member being fixedly connected to said front end portion of said first sleeve member, said second sleeve member enclosing another section of said second portion of said shaft member over a length corresponding to the remainder of said distance, said second sleeve member having a front end section facing said structure and a rear end section spaced from said front end section in said first direction, said second sleeve member being provided with a central bore having a first part adjacent said rear end section and a second part adjacent said front end section, said second part of said central bore being of a dimension in a second direction transverse to said first direction exceeding the respective dimension of said first part of said bore and corresponding to the outer dimension of said rear end portion of said first sleeve member, said second sleeve member having a shoulder located between said first and said second part of said central bore and extending substantially in said second direction, said rear end portion of said first sleeve member being received in said second part of said central bore of said second sleeve member with a friction fit and said rear end of said rear end portion of said first sleeve member abutting said shoulder of said second sleeve member so as to permit turning of said first and second sleeve members relative to one another, said flange portion being connected to said rear end section of said second sleeve member and having a surface extending in said second direction and abutting against said object to keep it at said distance from said structure, said abutting surface being in said second direction of a dimension exceeding the cross-section of said rear end section of said second sleeve member.
