Abstract
Abstract This disclosure relates to a coupling member for securing the butt ends of two panels to a central panel, and to the joint structure formed therewith. The coupling member is formed from first and second elongated members, the first elongated member having a tubular portion with internal and external threads, and an opposite end having a radial shoulder to abut the sides of a panel and an expanded head spaced therefrom. The second elongated member forming the coupling member has at one end a threaded stud to be received within the first elongated member tubular portion and at the other end a radial shoulder and an expanded head spaced therefrom. In the joint formed with the coupling member, the expanded heads engage flexible and resilient clips having slots to receive the ends of the coupling members and the clips are fixed within recesses in butt ends of two panels. The joints thus formed are flexible and hidden from view.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
103 words
A coupling member for joining the butt ends of two wall members to a central panel, said coupling member comprising: a first elongated member having a threaded axial bore at one end, an expanded head fixed at the other end of said first elongated member, and a radial shoulder spaced from said head between said head and said bore; and a second elongated member having a threaded end sized to threadably engage said axial opening of said first elongated member, a expanded head at an end opposite said threaded end, and a radial shoulder spaced inwardly from said second elongated member expanded head.
Claim 2
Dependent Claim
103 words
A coupling member for joining the butt ends of two wall members to a central panel, said coupling member comprising: a first elongated member having a threaded axial bore at one end, an expanded head fixed at the other end of said first elongated member, and a radial shoulder spaced from said head between said head and said bore; and a second elongated member having a threaded end sized to threadably engage said axial opening of said first elongated member, a expanded head at an end opposite said threaded end, and a radial shoulder spaced inwardly from said second elongated member expanded head.
Claim 3
Dependent Claim
24 words
A coupling member according to claim 1 wherein said first elongated member further comprises means on said outer surface for threadably engaging a bore.
Claim 4
Dependent Claim
34 words
A coupling member according to claim 2 wherein said thread means on the outer surface of said first elongated member are opposite in pitch to the pitch of the threads within said axial opening.
Claim 5
Dependent Claim
36 words
A coupling member according to claim 3 wherein said head of said second elongated member contains a tool-engaging means so that a tool can be employed to tightly secure said first and second elongated members together.
Claim 6
Dependent Claim
35 words
A coupling member according to claim 1 wherein said head of second elongated member contains a tool-engaging means so that a tool can be employed to tightly secure said first and second elongated members together.
Claim 7
Dependent Claim
99 words
A coupling member for joining the butt ends of two wall members to a central panel of relatively narrow width, said coupling member comprising; a first elongated member having a threaded axial bore at one end and an expanded head at the other end; the outer surface of said first elongated member being threaded at said one end to engage a bore in said central panel; and a second elongated member having a threaded end for threadably engaging said axial bore of said first elongated member; and an expanded head on an opposite end of said second elongated member.
Claim 8
Dependent Claim
99 words
A coupling member for joining the butt ends of two wall members to a central panel of relatively narrow width, said coupling member comprising; a first elongated member having a threaded axial bore at one end and an expanded head at the other end; the outer surface of said first elongated member being threaded at said one end to engage a bore in said central panel; and a second elongated member having a threaded end for threadably engaging said axial bore of said first elongated member; and an expanded head on an opposite end of said second elongated member.
Claim 9
Dependent Claim
34 words
A coupling member according to claim 6 wherein the threads on the outer surface of said first elongated member are pitched opposite to the threads within said axial bore of said first elongated member.
Claim 10
Dependent Claim
40 words
A coupling member according to claim 6 wherein said first elongated member has a radial shoulder spaced inwardly of said expanded head, and said second elongated member has a radial shoulder spaced inwardly of said second elongated member expanded head.
Claim 11
Dependent Claim
19 words
A coupling member according to claim 6 wherein said second elongated member expanded head has a tool-engaging slot at
Claim 12
Dependent Claim
