Abstract
Upstanding polysurfaced male and female lips are provided along confronting edges of adjacent elements, such as building panels. The female lip is engaged over the male lip and when rotated about the male lip is snap-fitted into interlocked relation therewith. The lips provide an upstanding joint which secures the adjacent elements in fixed angular relation to each other. The lips are interengaged along plural angularly spaced-apart regions and are overlapped such that vertical and lateral disengagement of either lip relative to the other is precluded along the entire length of the joint.
Claims25
A joint comprising:
- adjacent central webs presenting confronting first and second web edges,
- a polysurfaced female lip adjoined to the first web edge and comprising, in sequence, relative to the first central web edge:
- an upwardly and inwardly extending first element,
- an upwardly and outwardly extending second element,
- an outwardly extending third element,
- an outwardly and downwardly extending fourth element, and
- a re-entrant terminal element;
- a polysurfaced male lip adjoined to the second web edge and comprising:
- an upwardly and outwardly extending first leg overlapping said first element,
- a re-entrant arcuate terminal leg engaged with said re-entrant terminal element, and
- said first leg and said terminal leg being joined by at least two distinct legs and intermediate thereof at least one arcuate bend,
- said arcuate bend being in engagement with an interior surface of said female lip;
- said male lip being interlocked with said female lip thereby to provide said joint which secures the adjacent central webs in fixed angular relation to each other.
A roof structure comprising plural roofing panels assembled in side-by-side relation, supported on and secured to spaced-apart purlins, and connected in interlocked relation by plural upstanding joints, each of said joints comprising:
- adjacent ones of said roofing panels having central webs presenting confronting first and second web edges,
- an upstanding polysurfaced female lip adjoined to the first web edge and comprising:
- a first element extending upwardly from and inwardly over the first web edge,
- a second element extending upwardly from and outwardly of said first element,
- a third element extending laterally outwardly from said second element and beyond said first and second web edges,
- a fourth element extending outwardly of and downwardly from said third element, and
- a re-entrant terminal element adjoined to said fourth element and spaced above the central web of said first roofing panel;
- and
- an upstanding polysurfaced male lip adjoined to the second web edge and comprising:
- a first leg extending upwardly from and outwardly of the second web edge and overlapping said first element,
- a re-entrant arcuate terminal leg engaged with said re-entrant terminal element,
- said first leg and said re-entrant arcuate terminal leg being joined by at least two distinct legs and intermediate thereof at least one arcuate bend,
- said arcuate bend being in engagement with an interior surface of said female lip;
- said male lip being interlocked with said female lip thereby to secure adjacent roofing panels in fixed relation to each other.
An interlocking panel having a central web presenting a first web edge and opposite thereto a second web edge, and complementary lips, one adjoined to and extending along each said web edge, said complementary lips comprising:
- a polysurfaced female lip including, in sequence, relative to said first web edge:
- an upwardly and inwardly extending first element,
- an upwardly and outwardly extending second element,
- an outwardly extending third element,
- an outwardly and downwardly extending fourth element, and
- a re-entrant terminal element;
- and
- a polysurfaced male lip including, in sequence, relative to said second web edge:
- an upwardly and outwardly extending first leg,
- a re-entrant arcuate terminal leg disposed over and spaced from said central web,
- said first leg and said terminal leg being joined by at least two distinct legs and intermediate thereof at least one arcuate bend,
- said arcuate bend residing at a level above said terminal leg;
- said lips being configured for snap-fit engagement with complementary lips of adjacent ones of said panel thereby to secure the central webs thereof in fixed angularly spaced-apart relation relative to each other.
