Abstract
An expandable flashing device comprises first and second pieces of flashing material that overlap one another with hems or folded edges located on opposite lateral sides of the pieces that hold the pieces together, yet allow the pieces to slide or shift with respect to one another to selectively change the length of the device. In a first stowed position, the pieces overlap one another and in an expanded second position, the pieces may be pulled apart to increase an overall length of the pieces. The maximum length of material that overlaps between the pieces is defined as the overlap range. The overlap range defines the range to which the device can be shortened or lengthened to fit a particular installation. A flashing system and a method of installing flashing are also disclosed.
Claims20
A flashing device comprising:
- a first piece of shaped material having a length and opposite lateral side edges;
- a second piece of shaped material having a length and opposite lateral side edges;
- said opposite lateral side edges of said first and second pieces each having a hemmed edge formed thereon;
- said first piece having closed hems with bend angles of approximately 180° formed on each said opposite lateral side edges thereof;
- said second piece having partially open hems formed on each said opposite lateral side edges thereof, said open hems having bend angles less than said bend angles of said closed hems;
- and
- wherein said first piece overlaps said second piece and said closed hems and said partially open hems on each opposite lateral side edge are nested with one another.
(canceled)
A flashing device comprising:
- a first piece of shaped material having a length and opposite lateral side edges;
- a second piece of shaped material having a length and opposite lateral side edges;
- said opposite lateral side edges of said first and second pieces each having a hemmed edge formed thereon, each hemmed edge including a hem made in both said first and second pieces of material;
- wherein said hems on each opposite lateral side edge includes a closed hem and a partially open hem;
- and
- wherein said first piece selectively overlaps said second piece to cover said first piece and said closed hem is placed within said partially open hem on each opposite lateral side of said first and second pieces thereby enabling said pieces to be selectively slidable with one another to adjust a desired length of the flashing device between a minimum and maximum flashing length.
A flashing system comprising:
- A) a first flashing device comprising:
- a first piece of shaped material having a length and opposite lateral side edges;
- a second piece of shaped material having a length and opposite lateral side edges;
- said opposite lateral side edges of said first and second pieces each having a hemmed edge formed thereon, each hemmed edge including a hem made in both said first and second pieces of material;
- wherein said hems on each opposite lateral side edge includes a closed hem and a partially open hem;
- and wherein said first piece selectively overlaps said second piece to cover said first piece and said closed hem is placed within said partially open hem on each opposite lateral side of said first and second pieces;
- and
- B) a second flashing device comprising:
- a third piece of shaped material having a length and opposite lateral side edges;
- a fourth piece of shaped material having a length and opposite lateral side edges;
- said opposite lateral side edges of said third and fourth pieces each having a hemmed edge formed thereon, each hemmed edge of said third and fourth pieces including a hem made in both said first and second pieces of material;
- wherein said hems on each opposite lateral side edge includes a closed hem and a partially open hem;
- and wherein said third piece selectively overlaps said fourth piece to cover said fourth piece and said closed hem is placed within said partially open hem on each opposite lateral side of said third and fourth pieces;
- and
- wherein said third and fourth pieces are selectively slidable with one another to adjust a desired length of the flashing device between a minimum and maximum flashing length.
A method of installing flashing for use in weatherproofing a structure, said method comprising:
- providing a flashing device comprising:
- (i) a first piece of shaped material having a length and opposite lateral side edges;
- (ii) a second piece of shaped material having a length and opposite lateral side edges;
- (iii) said opposite lateral side edges of said first and second pieces each having a hemmed edge formed thereon, each hemmed edge including a hem made in both said first and second pieces of material;
- (iv) wherein said hems on each opposite lateral side edge includes a closed hem and a partially open hem;
- and (v) wherein said first piece selectively overlaps said second piece to cover said first piece and said closed hem is placed within said partially open hem on each opposite lateral side of said first and second pieces;
- determining a length on said structure that requires weatherproofing;
- installing said flashing device on said structure;
- and
- selectively sliding the first or second pieces to adjust a length of the flashing device between a minimum and maximum flashing length and to match said determined length on said structure.
