Mounting arrangement

Claim 2

A mounting arrangement for mounting an object to a support structure at a predetermined distance from the latter, comprising a sleeve-shaped dowel having an inner hole and insertable into a hole of the support structure; a mounting screw adapted to pass through a hole of the object to be mounted so as to support the latter, and partially insertable into said inner hole of said dowel, said mounting screw having a leading end and a trailing end as considered in the direction of insertion thereof into said dowel, and a head provided at said trailing end; and a sleeve-shaped spacer member having an inner hole adapted to be fitted onto said mounting screw and insertable into the hole of the object to be mounted, said spacer member having resiliently yieldable means adapted to be spring-loaded after insertion of said spacer member into the hole of the object to be mounted and operative for gripping the object to be mounted from a surface facing toward the support structure, when said spacer member is inserted in the hole of the latter, said spacer member having an upper portion lying on a surface of the object to be mounted, which faces away from the support structure, and provided with a ridge overlapping an end surface of said head of said mounting screw, which faces away from the support structure.

Claim 3

A mounting arrangement for mounting an object to a support structure at a predetermined distance from the latter, the object having a lower face and an upper face facing toward and away from the support structure, the mounting arrangement comprising a sleeve-shaped dowel having an inner hole and insertable into a hole of the support structure; a mounting screw adapted to pass through a hole of the object to be mounted so as to support the latter, and partially insertable into said inner hole of said dowel, said mounting screw having a leading end and a trailing end as considered in the direction of insertion thereof into said dowel, said mounting screw further having a head provided at said trailing end thereof and having a lower surface and an upper surface; and a sleeve-shaped spacer member having an inner hole and adapted to be fitted onto said mounting screw and insertable into the hole of the object to be mounted, said spacer member having resiliently yieldable means adapted to be spring-loaded after insertion of said spacer member into the hole of the object to be mounted and operative for gripping the latter in said spacer member, said spacer member having an upper portion located above and abutting against the upper face of the object to be mounted, when said spacer member is inserted in the object, said spacer member having further means for fixing the same to said mounting screw, said fixing means including a ridge formed in said upper portion of said spacer member and projecting inwardly from an inner wall bounding said inner hole of said spacer member in the region of said upper portion, said ridge partially overlapping said upper surface of said head of said mounting screw and thereby retaining said mounting screw from above.

Claim 4

A mounting arrangement for mounting an object to a support structure at a predetermined distance from the latter, the object having a lower face and an upper face facing toward and away from the support structure, the mounting arrangement comprising a sleeve-shaped dowel having an inner hole and insertable into a hole of the support structure; a mounting screw adapted to pass through a hole of the object to be mounted so as to support the latter, and partially insertable into said inner hole of said dowel, said mounting screw having a leading end and a trailing end as considered in the direction of insertion thereof into said dowel, said mounting screw further having a head provided at said trailing end thereof and having a lower surface and an upper surface; and a sleeve-shaped spacer member having an inner hole and adapted to be fitted onto said mounting screw and insertable into the hole of the object to be mounted, said spacer member having resiliently yieldable means adapted to be spring-loaded after insertion of said spacer member into the hole of the object to be mounted and operative for gripping the latter in said spacer member, said spacer member having an upper portion located above and abutting against the upper face of the object to be mounted, when said spacer member is inserted in the object, said spacer member having further means for fixing the same to said mounting screw, said fixing means including a ridge formed in said upper portion of said spacer member and projecting inwardly from an inner wall bounding said inner hole of said spacer member in the region of said upper portion, said ridge partially overlapping said upper surface of said head of said mounting screw and thereby retaining said mounting screw from above.

Claim 5

The arrangement as defined in claim 2, wherein said head of said mounting screw has an upper edge, said ridge of said spacer member forms with a remainder portion of said inner wall of said spacer member in the region of said upper portion thereof, a groove in which said edge of said head of said mounting screw engages.

Claim 6

The arrangement as defined in claim 2, wherein said inner hole of said spacer member has a radial extension in the region of said upper portion of said spacer member, a section of said inner wall bounding said radial extension of said inner hole partially overlapping said lower surface of said head of said mounting screw and thereby supporting said head of said mounting screw from below.

Claim 7

The arrangement as defined in claim 2, wherein the hole of the object to be mounted is bounded by a wall and said mounting screw has an outer surface, said spacer member being located between said outer surface of said mounting screw and the wall bounding the hole of the object to be mounted.

Claim 8

The arrangement as defined in claim 2, wherein said mounting screw is threadless in the region whereon said spacer member is to be fitted.

Claim 9

The arrangement as defined in claim 2, wherein said spacer member has an axis, and said gripping means includes an axial portion of said spacer member having an outer surface and provided with two substantially radial projections which are arranged on said outer surface.

Claim 10

The arrangement as defined in claim 7, wherein said axial portion is formed by two resiliently yieldable prongs extending in an axial direction of said spacer member.

Claim 11

The arrangement as defined in claim 7, wherein said radial projection is located downwardly beyond and engaging from below the lower face of the object to be mounted, when said spacer member is inserted in the hole of the latter.
