Abstract
The invention is a sill pan system that can be targeted for commercial and/or multi-family use and that works with ADA compliant thresholds. Specifically, the sill pan system includes a left end segment that is configured to fit in the bottom left corner of a framed-in door opening. The system also includes a right end segment that is configured to fit in the bottom right corner of a framed-in door opening. The left and right end segments are joined together at single seam. The top face of the sill pan is sloped to ensure that water and moisture is routed from the interior side of a building.
Claims20
A sill pan system for installation on a framed in door opening extending between bottom end portions of two vertical studs of the framed in door opening, the system comprising:
- a left end segment configured to be fitted at one end of the framed in door opening adjacent to the bottom end portion of a first vertical stud of the two vertical studs;
- a right end segment configured to be fitted at an opposite end of the framed in door opening adjacent to the bottom end portion of a second vertical stud of the two vertical studs;
- wherein the left end segment comprises:
- a left top panel comprising a left edge, a right edge, a length, and a width;
- a left vertical wall extending upward from the left edge of the left top panel and extending the width of the left top panel;
- an L-shaped left flange extending downward from a front edge of the left top panel and upward to contact a side edge of the left vertical wall;
- a lip positioned at the right edge of the left top panel, the lip defined as an extension adjacent to a top face of the left top panel with a thickness that is less than the thickness of the left top panel, wherein the decreased thickness is adjacent to the bottom face of the left top panel;
- wherein the right end segment comprises:
- a right top panel comprising a left edge, a right edge, a length, and a width;
- a right vertical wall extending upward from the right edge of the right top panel and extending the width of the right top panel;
- an L-shaped right flange extending downward from a front edge of the right top panel and upward to contact a side edge of the right vertical wall;
- a recessed region positioned at the left edge of the right top panel, the recessed region defined as an extension adjacent to a bottom face of the right top panel with a thickness that is less than the thickness of the right top panel, wherein the decreased thickness is adjacent to the top face of the right top panel;
- a plurality of spacing ribs positioned on a top face of the right end recessed region of the right top panel;
- a back dam positioned upward from the top face of the right top panel and the top face of the left top panel, the back dam comprising a height of at least 0.1 inch and no more than 0.1875 inches, wherein the back dam comprises a first segment comprising an area of reduced thickness adjacent to the lip of the left top panel, and wherein the back dam comprises a second segment of reduced thickness adjacent to the recessed region of the right top panel, wherein the back dam first and second segments of reduced thickness overlap;
- wherein the lip is configured to overlay the spacing ribs, thereby joining the left end segment to the right end segment at a seam;
- wherein the lip and the right recessed region overlap at a rear edge of the left and right top panels;
- and
- wherein the thickness of the lip and the thickness of the recessed region when overlapped is the same thickness of the left top panel and the same thickness as the right top panel.

A sill pan kit comprising:
- a plurality of left end segments, each left end segment defined by:
- a left top panel comprising a left edge, a right edge, a length, and a width;
- a left vertical wall extending upward from the left edge of the left top panel and extending the width of the left top panel;
- an L-shaped left flange extending downward from a front edge of the left top panel and upward to contact a side edge of the left vertical wall;
- a left panel back dam positioned at a rear edge of the left top panel, extending in an upward direction;
- a lip positioned at the right edge of the left top panel, the lip defined as an extension adjacent to a top face of the left top panel with a thickness that is less than the thickness of the left top panel, wherein the decreased thickness is adjacent to the bottom face of the left top panel;
- a plurality of right end segments, each right end segment defined by:
- a right top panel comprising a left edge, a right edge, a length, and a width;
- a right vertical wall extending upward from the right edge of the right top panel and extending the width of the right top panel;
- an L-shaped right flange extending downward from a front edge of the right top panel and upward to contact a side edge of the right vertical wall;
- a recessed region positioned at the left edge of the right top panel, the recessed region defined as an extension adjacent to a bottom face of the top right panel with a thickness that is less than the thickness of the right top panel, wherein the decreased thickness is adjacent to the top face of the right top panel;
- a plurality of spacing ribs positioned on a top face of the right end recessed region of the right top panel at the left edge of the right top panel;
- a back dam positioned upward from the top face of the right top panel and the top face of the left top panel, the back dam comprising a height of at least 0.1 inch and no more than 0.1875 inches, wherein the back dam comprises a first segment comprising an area of reduced thickness adjacent to the lip of the left top panel, and wherein the back dam comprises a second segment of reduced thickness adjacent to the recessed region of the right top panel, wherein the back dam first and second segments of reduced thickness overlap;
- wherein the lip is configured to overlay the spacing ribs, thereby joining the left end segment to the right end segment at a seam;
- wherein the lip and the recessed region overlap at a rear edge of the left and right top panels;
- wherein the thickness of the lip and the thickness of the recessed region when overlapped is the same thickness of the left top panel and the same thickness as the right top panel;
- wherein one of the plurality of left end segments can be joined to one of the plurality of right end segments to create an assembled sill pan system.
