Abstract
Methods and devices for joining two or more panels together are provided. The methods allow joining of panels of material such as glass fiber board, and are particularly useful for forming ducts or tubes. Fasteners provided have two planar members, joined together, and the planar members have protrusions that are integral to the planar members and are intended to at least partially protrude the panels joined by the devices.

9. A method for joining a first panel and a second panel comprising the steps of:
-
providing a fastener comprising a first planar member and a second planar member, said first and second planar members being contiguous and having teeth-like projections thereon, and wherein at least one of said planar members has a mounting tab extending therefrom for mounting said fastener to a mounting surface;
contacting said first panel with said first planar member such that said projections on said first planar member at least partially penetrate said first panel; and
contacting said second panel with said second planar member such that said projections on said second planar member at least partially penetrate said second panel. - View Dependent Claims (10, 11, 12)
-
- 13. A duct system comprising at least a first duct segment and a second duct segment, said first and second duct segments joined by at least one fastener comprising two adjacent planar members, said planar members comprising teeth-like projections thereon, and wherein said planar members are contiguous to one another, such that at least one of said projections at least partially penetrates said first duct segment and at least one of said projections at least partially penetrates said second duct segment.
-
15. A duct formed by joining at least three panels, by applying to said panels a plurality of fasteners, each fastener comprising at least two contiguous planar members, each planar member comprising teeth-like projections thereon, whereby said projections penetrate at least partially into said panels, and wherein at least one of said planar members has a mounting tab extending therefrom for mounting said fastener to a mounting surface, said panels together forming said duct.
-
16. A method for forming a duct comprising the steps of:
-
providing a sheet of material having a first longitudinal edge and a second longitudinal edge;
folding said sheet of material in a direction parallel to said longitudinal edges so that said longitudinal edges are brought into contact and form a longitudinal seam; and
applying to said folded sheet, across said longitudinal seam, a fastener comprising two adjacent planar members, each planar member comprising teeth-like projections thereon, said projections integral with said member, and said planar members contiguous to one another, such that at least one of said projections at least partially penetrates said first longitudinal edge and at least one of said projections at least partially penetrates said second longitudinal edge, and wherein at least one of said planar members has a mounting tab extending therefrom for mounting said fastener to a mounting surface.

17. A method for joining a first panel and a second panel comprising the steps of:
-
providing a fastener comprising a first planar member and a second planar member, said first and second planar members being contiguous and having teeth-like projections thereon, and wherein each planar member has a slot and wherein said members are joined by interconnecting said slots;
contacting said first panel with said first planar member such that said projections on said first planar member at least partially penetrate said first panel; and
contacting said second panel with said second planar member such that said projections on said second planar member at least partially penetrate said second panel.

18. A method for forming a duct comprising the steps of:
-
providing a sheet of material having a first longitudinal edge and a second longitudinal edge;
folding said sheet of material in a direction parallel to said longitudinal edges so that said longitudinal edges are brought into contact and form a longitudinal seam; and
applying to said folded sheet, across said longitudinal seam, a fastener comprising two adjacent planar members, each planar member comprising teeth-like projections thereon, said projections integral with said member, and said planar members contiguous to one another, such that at least one of said projections at least partially penetrates said first longitudinal edge and at least one of said projections at least partially penetrates said second longitudinal edge, and wherein each planar member has a slot and wherein said members are joined by interconnecting said slots.

19. A duct formed by joining at least three panels, by applying to said panels a plurality of fasteners, each fastener comprising at least two contiguous planar members, each planar member comprising teeth-like projections thereon, whereby said projections penetrate at least partially into said panels, and wherein each planar member has a slot and wherein said members are joined by interconnecting said slots.
