A paneling system having a supporting member and a plurality of panels each of which is provided at the ends thereof with interlocking flanges, the interlocking flange located at one end of the panel having a portion extending from the panel to the supporting member engaging same and thereafter extending away from the supporting member terminating in an end that is positioned in spaced relationship from the remainder of the flange, a fastener securing the flange to the supporting member, and wherein the interlocking flange at the other end of the panel has a portion extending from the panel which engages only a part of the corresponding portion of the other interlocking flange extending to a point near the supporting member and thereafter backwardly toward the end of the other interlocking flange terminating in an end which engages the end of the other interlocking flange.
A paneling system, comprising a supporting member, a plurality of panels, each of said panels being provided with first and second interlocking flanges that are flexible, said first interlocking flanges having portions extending from said panels to said supporting member engaging said supporting member and then extending away from said supporting member terminating in ends spaced from said portions that extend from said panels, means fastening those portions of said first interlocking flanges that engage said supporting members to said supporting member, said second interlocking flanges having portions extending from said panels which engage only parts of said portions of said first interlocking flanges that extend from said panels and extending to the vicinity of said supporting member and then extending away from said supporting member toward said ends of said first interlocking flanges terminating in ends which engage said ends of said first interlocking flanges, said ends of said second interlocking flanges being spaced from said portions thereof which extend from said panels distances sufficient to force said ends of said first interlocking flanges outwardly until said second interlocking flanges are secured in place within said first interlocking flanges at which time said ends of said first interlocking flanges assume their original positions, and wherein said portions of said first interlocking flanges that extend from said panels to said supporting member are positioned approximately perpendicular to said supporting member, and wherein said portions of said first interlocking flanges that extend away from said supporting member form an angle with those portions of said first interlocking flanges that engage said supporting member that is approximately 90.degree., and wherein said ends of said first interlocking flanges terminate in lips extending toward said portions of said first interlocking flanges that extend from said panels, and wherein said portions of said second interlocking flanges that extend from said panels and which engage only parts of said portions of said first interlocking flanges are defined by two segments which intersect each other at angles slightly less than 180.degree., and wherein said portions of said second interlocking flanges which extend toward said ends of said first interlocking flanges are positioned diagonally from the points at which said portions of said first interlocking flanges engage said supporting member and said lips of said first interlocking flanges.
A panel, comprising a central portion terminating at one end in a female flange and at the other end in a male flange, said female flange having a generally flat portion that extends from said central portion and another portion that terminates in an end that is spaced from said flat portion, said end being provided with a lip extending towards said flat portion, said male flange having a portion extending from said central portion that consists of two segments which intersect each other at an angle slightly less than 180.degree. such that only portions of said two segments of said male flange engage said flat portion of said female flange of an adjacent of said panels and another portion extending toward said central portion for engaging said lip of said female flange of an adjacent of said panels.
In a paneling system having a plurality of interlocking panels wherein each of the panels has a wall terminating in interlocking flanges at each end thereof, the improvement comprising one of said flanges having a first section that extends outwardly from said wall, a substantial portion of said first section being generally perpendicular to said wall, a second section that extends outwardly from said first section and which is generally perpendicular thereto, a third section that extends outwardly from said second section, the angle formed between said second and third sections being approximately 90.degree., said third section terminating in a lip extending towards said first section, and wherein the other of said flanges has a fourth section that extends outwardly from said wall, a fifth section extending from said fourth section at an angle slightly less than 180.degree. such that only limited portions of said fourth and fifth sections engage said first section of said one of said flanges of an adjacent panel, a sixth section extending from said fifth section and terminating in an end positioned slightly beyond said lip of said third section of said one of said flanges of an adjacent panel such that said end of said sixth section forces said third section outwardly until said end passes said lip.
A paneling system, comprising a supporting member, a plurality of panels suspended from said supporting member, each of said panels being provided with first and second interlocking flanges that are flexible, said first interlocking flanges having portions extending from said panels to said supporting member engaging said supporting member and then extending away from said supporting member terminating in ends spaced from said portions that extend from said panels, means fastening those portions of said first interlocking flanges that engage said supporting member to said supporting member, said second interlocking flanges having portions extending from said panels which engage only parts of said portions of said first interlocking flanges that extend from said panels and extending to the vicinity of said supporting member and then extending away from said supporting member toward said ends of said first interlocking flanges terminating in ends which engage said ends of said first interlocking flanges, said ends of said second interlocking flanges being spaced from said portions thereof which extend from said panels sufficient distances to force said ends of said first interlocking flanges outwardly until said second interlocking flanges are secured in place within said first interlocking flanges at which time said ends of said first interlocking flanges assume their original positions.
