Abstract
Abstract An assembly is used to space facade panels and/or facade supports from a structural support member and the assembly is made up of a support member, a dowel and an expansion screw. The support member is resilient and is provided with stop shoulders so that it can be inserted into an opening in the facade panel or facade support with the shoulders bearing against the panel or support. A dowel is inserted through and is interengaged with the support member. The dowel is inserted into a borehole in the structural support member and the expansion screw secures the dowel within the borehole.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
139 words
A method of assembling facade members in spaced relation to a structural support using a dowel which can be anchored into the structural support and a support member which can be secured in an opening in the facade member, comprising the steps of inserting the support member into the opening in the facade member, insterengaging the support member within the opening in the facade member so that the support member is secured against displacement relative to the facade member, inserting the dowel through the support member and interengaging the dowel and the support member so that the dowel is secured against displacement relative to the support member, inserting the dowel secured to the support member and the facade member into a prepared borehole in the structural support and then anchoring the dowel within the borehole in the structural support.
Claim 2
Independent Claim
139 words
A method of assembling facade members in spaced relation to a structural support using a dowel which can be anchored into the structural support and a support member which can be secured in an opening in the facade member, comprising the steps of inserting the support member into the opening in the facade member, insterengaging the support member within the opening in the facade member so that the support member is secured against displacement relative to the facade member, inserting the dowel through the support member and interengaging the dowel and the support member so that the dowel is secured against displacement relative to the support member, inserting the dowel secured to the support member and the facade member into a prepared borehole in the structural support and then anchoring the dowel within the borehole in the structural support.
Claim 3
Dependent Claim
118 words
An assembly for mounting facade members in spaced relation to a structural support, said assembly comprising an axially extending support member having a pair of stop shoulders spaced apart in and extending transversely of the axial direction of said support member and arranged to bear against the facade member for securing said support member to the facade member, said support member having a bore extending axially therethrough, an axially extending dowel insertable through said bore in said support member, first and second engaging means on said support member and said dowel for securing said dowel within the bore in said support member, and said first and second engaging means spaced apart in the axial direction of said dowel.
Claim 4
Dependent Claim
118 words
An assembly for mounting facade members in spaced relation to a structural support, said assembly comprising an axially extending support member having a pair of stop shoulders spaced apart in and extending transversely of the axial direction of said support member and arranged to bear against the facade member for securing said support member to the facade member, said support member having a bore extending axially therethrough, an axially extending dowel insertable through said bore in said support member, first and second engaging means on said support member and said dowel for securing said dowel within the bore in said support member, and said first and second engaging means spaced apart in the axial direction of said dowel.
Claim 5
Dependent Claim
35 words
An assembly, as set forth in claim 2, wherein said support member has a pair of oppositely facing end faces extending transversely of the axial direction thereof, and said end faces forming said stop shoulders.
Claim 6
Dependent Claim
53 words
An assembly, as set forth in claim 2, wherein said support member has a circumferentially extending annular groove formed in the outside surface thereof, said groove having a pair of opposite flanks extending transversely of the axial direction of said support member and said flanks face one another and form said stop shoulders.
Claim 7
Dependent Claim
71 words
An assembly, as set forth in claim 2, 3 or 4, wherein said support member has a number of angularly spaced axially extending slots from one transverse end thereof to a location adjacent to but spaced from the other transverse end and said slots divide said support member into a plurality of radially resilient interconnected segments, and at least one of said stop shoulders is formed in said radially resilient segments.
Claim 8
Dependent Claim
46 words
An assembly, as set forth in claim 2, 3 or 4, wherein an annular shaped stop extends axially outwardly from one end face of said support member and is arranged to engage an opening through the facade member support for securing said support member in position.
Claim 9
Dependent Claim
84 words
An assembly, as set forth in claim 2, wherein axially extending slots are formed in said dowel in the region thereof secured within said support member and said slots divide said dowel into a number of radially resilient segments, and said first and second engaging means comprises a pair of axially spaced annular shoulders formed on the radially resilient segments of said dowel and corresponding surfaces formed on said support member for effecting the locking engagement between said dowel member and said support member.
Claim 10
Dependent Claim
21 words
An assembly, as set forth in claim 2, 3 or 4, wherein said support member has a frusto-conically shaped outside surface.
Claim 11
Dependent Claim
28 words
An assembly, as set forth in claim 2, 3 or 4, wherein said support member has the shape of a rectangular parallelepiped tranversely of the axial direction thereof.
