Abstract
Abstract A fastening element with an adjustment flange and an eccentric segment for objects to be suspended as, in particular, heating elements or convectors, which engages into bores of an attachment wall and a rear wall of the object lying opposite each other, has between an outer adjustment flange and an inner flange an adjustment eccentric clamped eccentrically with respect to the flanges for compensation of alignment errors of the bores, whereby the surface of the inner flange facing away from the eccentric comes to rest against the attachment wall externally of the bore receiving a bolt and the adjustment eccentric slid loosely upon the bolt is arranged only in the area of the bore of the rear wall to be pivotable around the bolt from outside of the bore.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
324 words
In a fixing device for mounting an object on a support, such as for mounting heating elements or convectors, comrpising a fastening element including an adjsutment mounting flange and an adjusting eccentric, said fastening element arranged to be installed into a bore in the support on which the object is to be mounted, the object to be mounted has a bore therethrough arranged to be in general alignment with the bore in the support, wherein the improvement comprises that said fastening element comprises an axially elongated bolt having a first axially extending section arranged to extend into the bore in the support and a second axially extending section arranged to extend out of the bore in the support and through the bore in the object, said adjustment mounting flange (13) is positioned on the second axially extending section so that it is spaced outwardly from the support, an inner flange (8) located on the second axially extending section between said mounting flange (13) and the support, said inner flange (8) spaced axially from said mounting flange, said adjusting eccentric (12) is mounted on said bolt between said inner flange and said mounting flange, said adjusting eccentric (12) being eccentric to said bolt and said inner and outer mounting flanges, said inner flange having a pair of opposite surfaces extending transversely of the axial direction of said bolt with one surface arranged to bear against the support surface and the other surface arranged to bear against said adjusting eccentric, said adjusting eccentric (12) being rotably mounted on said bolt (2) and arranged to extend through and contact the surface of the bore in the object to allow for any inaccuracy in the relative positions of said bolt and the bore in the object, and said eccentric includes a plurality of discs arranged face to face, means rotatably mounting said discs on said bolt and means keying said discs together for simultaneous rotation on said bolt.

Claim 3
Dependent Claim
36 words
A device as claimed in claim 1, further comprising a flange nut incorporated in said mounting flange and means keying said mounting flange to said eccentric, whereby rotation of said mounting flange also rotates said eccentric.
Claim 4
Dependent Claim
14 words
A device as claimed in claim 2, in which said flange nut is hexagonal.
Claim 5
Dependent Claim
63 words
A device as claimed in claim 1, further comprising means defining a recess in said inner flange, said adjusting eccentric engaging in said recess and said recess being concentric with said bolt and having a diameter which permits said eccentric to move radially to its full extent within said recess upon rotation of said eccentric on said bolt relative to said inner flange.
Claim 6
Dependent Claim
59 words
A device as claimed in claim 4, further comprising a hub on said inner flange, said hub projecting from said inner flange in a direction opposite to the face of said inner flange in which said recess is formed, and a peripheral collar on said inner flange projecting from said inner flange in the same direction as said hub.
Claim 7
Dependent Claim
25 words
A device as claimed in claim 1, further including indicator means indicating the direction of offset of said eccentric from the axis of said bolt.
Claim 8
Dependent Claim
39 words
A device as claimed in claim 3, further including indicator means indicating the directon of offset of said eccentric from the axis of said bolt, in which said indicator means is on the outer face of said flange nut.
Claim 9
Dependent Claim
18 words
A device as claimed in claim 3, in which said flanges and said eccentric are of plastics material.
Claim 10
Dependent Claim
27 words
A device as claimed in claim 1, in which anhoring means for securing said bolt includes an expansion sleeve mounted on the first section of said bolt.
Claim 11
Dependent Claim
23 words
A device as claimed in claim 9, further comprising a protective sleeve mounted on said bolt between said expansion sleeve and said eccentric.
Claim 12
Dependent Claim
53 words
A device as claimed in claim 1, further comprising a head on one end of said bolt formed by the first section thereof, a nut screwed onto the other end of said bolt formed by the second section thereof, said eccentric and said anchoring means being situated between said head and said nut.
