Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
343 words
A mounting plate for furniture hinges, said mounting plate being of the type adapted to be secured to a first furniture element and adapted to support a hinge arm which is hingedly connected to a second furniture element, said mounting plate comprising: a plate member; at least one rigid expansion member integrally and immovably fixed to said plate member and extending therefrom, said expansion member having a first axial end adjacent said plate member and a second axial end spaced therefrom; a dowel member formed of a deformable material and having an axial opening, said expansion member extending into said axial opening, with said dowel member surrounding said expansion member, said dowel member having a first axial end and a second axial end respectively adjacent said first and second axial ends of said expansion member; said dowel member having an exterior having outwardly extending ribs adapted to be anchored in a wall of a bore in a first furniture element when said dowel member and expansion member are inserted therein; said expansion member being mounted within said dowel member for limited axial movement relative thereto, such that when an external force is applied to said plate member to move said plate member away from the first furniture element, said expansion member will move axially of said dowel member, in a direction from said second end thereof to said first end thereof, by a limited extent; said dowel member having opposite interior surfaces converging from said second end to said first end of said dowel member; said expansion member having opposite exterior surfaces, complementary to said interior surfaces, converging from said second end to said first end of said expansion member; and said interior surfaces and said exterior surfaces being dimensioned such that upon axial movement of said expansion member with respect to said dowel member, said exterior surfaces of said expansion member will bear against said interior surfaces of said dowel member, thereby deforming said dowel member and forcing said ribs further against the wall of the bore in the first furniture element.
Claim 2
Dependent Claim
343 words
A mounting plate for furniture hinges, said mounting plate being of the type adapted to be secured to a first furniture element and adapted to support a hinge arm which is hingedly connected to a second furniture element, said mounting plate comprising: a plate member; at least one rigid expansion member integrally and immovably fixed to said plate member and extending therefrom, said expansion member having a first axial end adjacent said plate member and a second axial end spaced therefrom; a dowel member formed of a deformable material and having an axial opening, said expansion member extending into said axial opening, with said dowel member surrounding said expansion member, said dowel member having a first axial end and a second axial end respectively adjacent said first and second axial ends of said expansion member; said dowel member having an exterior having outwardly extending ribs adapted to be anchored in a wall of a bore in a first furniture element when said dowel member and expansion member are inserted therein; said expansion member being mounted within said dowel member for limited axial movement relative thereto, such that when an external force is applied to said plate member to move said plate member away from the first furniture element, said expansion member will move axially of said dowel member, in a direction from said second end thereof to said first end thereof, by a limited extent; said dowel member having opposite interior surfaces converging from said second end to said first end of said dowel member; said expansion member having opposite exterior surfaces, complementary to said interior surfaces, converging from said second end to said first end of said expansion member; and said interior surfaces and said exterior surfaces being dimensioned such that upon axial movement of said expansion member with respect to said dowel member, said exterior surfaces of said expansion member will bear against said interior surfaces of said dowel member, thereby deforming said dowel member and forcing said ribs further against the wall of the bore in the first furniture element.
Claim 3
Dependent Claim
26 words
A mounting plate as claimed in claim 1, wherein said ribs diverge outwardly from said second end of said dowel member to said first end thereof.
Claim 4
Dependent Claim
18 words
A mounting plate as claimed in claim 1, wherein said axial opening extends entirely through said dowel member.
Claim 5
Dependent Claim
19 words
A mounting plate as claimed in claim 1, wherein said axial opening extends only partially through said dowel member.
Claim 6
Dependent Claim
34 words
A mounting plate as claimed in claim 4, wherein said opposite interior surfaces comprise portions of an interior truncated conical surface, and said opposite exterior surfaces comprise portions of an exterior truncated conical surface.
Claim 7
Dependent Claim
34 words
A mounting plate as claimed in claim 1, wherein said opposite interior surfaces comprise portions of an interior truncated conical surface, and said opposite exterior surfaces comprise portions of an exterior truncated conical surface.
Claim 8
Dependent Claim
32 words
A mounting plate as claimed in claim 1, wherein said opposite interior surfaces comprise portions of plural truncated conical surfaces, and said opposite exterior surfaces comprise portions of plural truncated conical surfaces.
Claim 9
Dependent Claim
29 words
A mounting plate as claimed in claim 1, wherein said dowel member has therein axially extending slots opening alternately on said first and second ends of said dowel member.
Claim 10
Dependent Claim
52 words
A mounting plate as claimed in claim 1, wherein said dowel member comprises plural circumferentially extending cylindrical segments having adjacent axial edges, one of said adjacent axial edges having therein holes, the other of said adjacent axial edges having extending therefrom plugs, said plugs extending into said holes, thereby joining said segments.
Claim 11
Dependent Claim
24 words
A mounting plate as claimed in claim 1, futher comprising means for limiting said axial movement between said expansion member and said dowel member.
Claim 12
Dependent Claim
61 words
A mounting plate as claimed in claim 10, wherein said limiting means comprises a recess in said second end of said dowel member, said recess having a stop face, and an annular ring extending outwardly from said second end of said expansion member, said ring extending into said recess and adapted to abut said stop face to limit said axial movement.
Claim 13
Dependent Claim
24 words
A mounting plate as claimed in claim 11, wherein the axial dimension of said recess is greater than the axial dimension of said ring.
Claim 14
Dependent Claim
78 words
A mounting plate as claimed in claim 10, wherein said dowel member comprises first and second cylindrical segments, said opposite interior surfaces comprise first and second laterally extending interior surfaces separating said first and second segments and having a spacing therebetween which varies in the axial direction of said dowel member, and said opposite exterior surfaces comprise first and second laterally extending exterior surfaces having a spacing therebetween which varies in the axial direction of said expansion member.
Claim 15
Dependent Claim
54 words
A mounting plate as claimed in claim 13, wherein said limiting means comprises first and second axially extending slots in said first and second segments, said slots having axially opposite ends spaced from said ends of said dowel member, and projections extending outwardly from said expansion member and axially slidably positioned within said slots.
Claim 16
Dependent Claim
41 words
A mounting plate as claimed in claim 14, wherein said projections have enlarged heads, and said slots have inwardly directed portions, said heads fitting in said slots exteriorly of said inwardly directed portions, thereby holding said segments on said expansion member.
Claim 17
Dependent Claim
50 words
A mounting plate as claimed in claim 1, wherein said opposite interior surfaces comprise portions of a spiral surface extending substantially throughout the axial length of said dowel member, and said opposite exterior surfaces comprise portions of a spiral surface extending substantially throughout the axial length of said expansion member.
