Abstract
Abstract A structural panel assembly includes a plurality of individual panel members hingedly connected one to each other by means of a common fulcrum-type hinge assembly which provides a 360* orientation for each of the individual panel members. The common fulcrum-type hinge assembly is composed of a pair of threaded members comprising a male portion and a female portion. The head of the male portion is circumferentially axially recessed to provide a circumferential retaining channel, and each of the panel members is provided with lugs at each of their corners which are adapted to fit the circumferential channel in the head of the male member of the hinge assembly for retainment of the individual panel members in various angular positions relative to each other.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
150 words
In a structural partition wall assembly comprised of a plurality of partitions interconnected one to each other on a common fulcrum axis, the improvement comprising a pair of partition connector assembly one each disposed at the bottom and the top of said plurality of partitions, each connector assembly characterized by a first member disposed between adjoining lateral edges of said plurality of partitions parallel to the fulcrum axis; a second member secured in a removable manner to said first member in axially aligned relationship, said second member having a head portion, said head portion having an annular groove therein, cooperating flange means connected to the top and bottom edge of each of said partitions and received within said annular groove of said second member and retained therein by said first member engaging said flange means to thereby retain said partition in radially disposed positions with respect to said connector assembly.
Claim 2
Dependent Claim
150 words
In a structural partition wall assembly comprised of a plurality of partitions interconnected one to each other on a common fulcrum axis, the improvement comprising a pair of partition connector assembly one each disposed at the bottom and the top of said plurality of partitions, each connector assembly characterized by a first member disposed between adjoining lateral edges of said plurality of partitions parallel to the fulcrum axis; a second member secured in a removable manner to said first member in axially aligned relationship, said second member having a head portion, said head portion having an annular groove therein, cooperating flange means connected to the top and bottom edge of each of said partitions and received within said annular groove of said second member and retained therein by said first member engaging said flange means to thereby retain said partition in radially disposed positions with respect to said connector assembly.
Claim 3
Dependent Claim
59 words
The improvement as defined in claim 1 characterized by one of said first and said second members having a threaded bore and the other of said first and said second members having a threaded shank portion rotatively engaged therewith and means associated with said radial flange portion to permit rotation of said first member relative to said second member.
Claim 4
Dependent Claim
44 words
The improvement as defined in claim 1 characterized in that said flange means of said partitions are curvilinearly shaped in a direction parallel to the axis of said annular groove and in correspondence with the curvature of the annular recess in said head portion.
Claim 5
Dependent Claim
39 words
The improvement as defined in claim 1 characterized by each of said first members having a radial flange means in concentric opposed relationship to said annular groove for retaining said flange means of said panel members by abutment therewith.
Claim 6
Dependent Claim
70 words
The improvement as defined in claim 4 characterized by one of said first members comprising a nut having a threaded bore, and the cooperative second member therefore having a threaded shank portion for rotative engagement within said threaded bore and said annular groove in the said second member being located in a plane normal to the axis of the threaded bore and threaded shank portion and in concentric relationship therewith.
Claim 7
Dependent Claim
48 words
The improvement as defined in claim 5 characterized by said second member having a head portion defining a cap; said annular groove being located in the inner surface of said cap; said cap being adapted to circumferentially engage and enclose flange means of said plurality of adjoining partitions.
Claim 8
Dependent Claim
45 words
The improvement as defined in claim 1 further characterized by the provision of a tubular member extending between said pair of upper and lower connector assemblies; said first members of said pair of connector assemblies being retained within the open ends of said tubular member.
Claim 9
Dependent Claim
27 words
The improvement as defined in claim 7, characterized in that said one of first members is non-rotatably attached within said tubular member adjacent an open end thereof.
