Abstract
Abstract Joint retention means in the form of a clip, for confining a male lip of a first panel within a fixed female lip of a second panel, against withdrawal by negative wind loading. The retention clip presents at least one wing element which is flexible in a direction normal to the general plane of the panel, and is relatively inflexible in a direction parallel with the direction of withdrawal of the male lip from the female lip.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
204 words
In a joint between adjacent panels wherein said panels present confronting first and second side walls extending inwardly toward a supporting structure, a female lip extending laterally from the first side wall and inwardly of the panel, a male lip extending laterally from the second side wall into said female lip, the improvement comprising: first means for securing said female lip to said supporting Structure; and second means for retaining said male lip engaged with said female lip, including at least one wing element extending outwardly from said supporting structure and presenting a longitudinal edge in confronting relation with a face of the second side wall which is remote from the first side wall, said wing element being flexible in a direction parallel with the second side wall and being relatively inflexible in a direction normal to the second side wall; said female lip presenting a terminal flange portion extending laterally of said first and second side walls and inwardly of said second panel; a base formed integrally with said wing element and engaged with said terminal flange portion; and said first means for securing said female lip to said supporting structure comprising a fastener extending through said base and said terminal flange portion.
Claim 2
Dependent Claim
204 words
In a joint between adjacent panels wherein said panels present confronting first and second side walls extending inwardly toward a supporting structure, a female lip extending laterally from the first side wall and inwardly of the panel, a male lip extending laterally from the second side wall into said female lip, the improvement comprising: first means for securing said female lip to said supporting Structure; and second means for retaining said male lip engaged with said female lip, including at least one wing element extending outwardly from said supporting structure and presenting a longitudinal edge in confronting relation with a face of the second side wall which is remote from the first side wall, said wing element being flexible in a direction parallel with the second side wall and being relatively inflexible in a direction normal to the second side wall; said female lip presenting a terminal flange portion extending laterally of said first and second side walls and inwardly of said second panel; a base formed integrally with said wing element and engaged with said terminal flange portion; and said first means for securing said female lip to said supporting structure comprising a fastener extending through said base and said terminal flange portion.
Claim 3
Dependent Claim
75 words
The improvement of claim 1 wherein said second means includes a second wing element extending outwardly from said base in a direction opposite to that of the first said wing element and having longitudinal edge presented in confronting relation with said face of the second side wall, said second wing element being flexible in a direction parallel with the second side wall and being relatively inflexible in a direction normal to the second side wall.
Claim 4
Dependent Claim
198 words
In a joint between adjacent first and second panels wherein said first and second panels present confronting first and second side walls, respectively, extending inwardly toward a supporting structure, a female lip extending laterally from the first side wall and inwardly of said first panel, a male lip extending laterally from the second side wall into said female lip, the improvement comprising: a first clip member having one end secured to said female lip and an opposite end confronting said supporting structure; a second clip member having a base engaged with said supporting structure and said opposite end of said first clip member, and diverging wing elements extending in opposite directions from opposite sides of said base and presenting corresponding longitudinal edges in confronting relation with a face of the second side wall which is remote from the first side wall, said wing elements being flexible in a direction parallel with said face of the second side wall and being relatively inflexible in a direction normal to said face of the second side wall; and fastening means securing said opposite end of said first clip member and said base of said second clip member to said supporting structure.
Claim 5
Dependent Claim
198 words
In a joint between adjacent first and second panels wherein said first and second panels present confronting first and second side walls, respectively, extending inwardly toward a supporting structure, a female lip extending laterally from the first side wall and inwardly of said first panel, a male lip extending laterally from the second side wall into said female lip, the improvement comprising: a first clip member having one end secured to said female lip and an opposite end confronting said supporting structure; a second clip member having a base engaged with said supporting structure and said opposite end of said first clip member, and diverging wing elements extending in opposite directions from opposite sides of said base and presenting corresponding longitudinal edges in confronting relation with a face of the second side wall which is remote from the first side wall, said wing elements being flexible in a direction parallel with said face of the second side wall and being relatively inflexible in a direction normal to said face of the second side wall; and fastening means securing said opposite end of said first clip member and said base of said second clip member to said supporting structure.
Claim 6
Dependent Claim
