(19) Referring to FIG. 1, there is illustrated a perspective view of a recessed window opening structure 3000. Conventionally, a recessed window opening structure is a window which is positioned in a plane, primarily a vertical plane, set inwardly from an outer wall of a structure. FIG. 1 is a perspective view of an example of a recessed window opening structure 3000. The outer wall numbered 1000 is made of material which is either wood or wood and a composite. Reading clockwise beginning on the left side, the outer wall 1000 includes a left vertical outer wall portion 1020, an upper horizontal outer wall portion 1080, a right vertical outer wall portion 1040 and a lower horizontal wall portion 1060. Set within the outer wall 1000 is a recessed window opening 1100. Reading clockwise from left to right, the recessed window opening 1100 is formed with a left recessed window opening jamb 1160, an upper horizontal buck #1 (2120), a right recessed window opening jamb 1180 and a recessed opening sill 1120. For purposes on the present invention, two important corners are the left lower recessed corner 1200 where the recessed opening sill 1120 and the left recessed window opening jamb 1160 come together; and the right lower recessed corner 1300 where the recessed opening sill 1120 and right recessed window opening jamb 1180 come together.

(20) Set interior of recessed window opening 1100, reading clockwise from left to right is, left vertical buck #1 (2220), upper horizontal buck #1 (2120), right vertical buck #1 (2340) (See FIG. 10) and lower horizontal buck #1 (2020). Set within the buck #1 members, again reading clockwise from left to right are left vertical buck #2 (2240), upper horizontal buck #2 (2140), right vertical buck #2 (2320), and lower horizontal buck #2 (2040). Set within and partially formed by the #2 buck members is the window opening 2900 including, again clockwise from left to right is the left window opening jamb 3240, the window opening head 3140, the right window opening jamb 3320 (see FIG. 10), and the window opening sill 3040. Included for discussion purposes in this application, four additional relevant corners are lower left buck #1 corner 2700 formed where lower horizontal buck #1 (2020) and left vertical buck #1 (2220) come together; and lower right buck #1 corner 2800 (see FIG. 10) formed where lower horizontal buck #1 (2020) and right vertical buck #1 (2340) (See FIG. 10) come together. Again reading clockwise from left to right are lower left window corner 2150 formed where the window opening sill 3040 and the left window opening jamb 3240 come together and the lower right window corner 2250 formed where the window opening sill 3040 and the right window opening jamb 3320 (see FIG. 1 and FIG. 10) come together.

(21) Referring to FIGS. 2 through 9, there are illustrated the views of an embodiment of the present invention corner flashing insert for recessed windows, which has the following significant improvements:

(22) 1. The corner flashing insert 10 is a one-piece, pre-formed flashing sized to fit into the three most common sized left lower recessed corner 1200 and right lower recessed corner 1300 of a recessed window opening structure 3000.

(23) 2. The corner flashing insert 10 provides three legs of protection. The corner flashing insert 10 includes an outside wall leg 20 having a vertical portion of the outside wall leg in a vertical plane 30, an outside wall leg angle 40 with an outside wall leg angle edge 40-E, and a horizontal portion of the outside wall leg in a vertical plane 50 which are oriented in a first vertical plane when the corner flashing 10 is inserted into either left lower recessed corner 1200 or right lower recessed corner 1300. The previously described components of the outside wall leg 20 cover the outer wall 1000 at the location adjacent the left lower recessed corner 1200 and/or the right lower recessed corner 1300 of a recessed window opening structure 3000.

(24) When used as an insert in right lower recessed corner 1300 as illustrated in FIGS. 10 and 11, the outside wall leg in a vertical plane 30 serves to cover the right vertical outer wall portion 1040 and the outside wall leg in a horizontal plane 50 serves to cover the lower horizontal wall portion 1060. The outside wall leg angle 40 covers an integration area. The angled portion of outside wall leg angle 40 is preferably cut at a forty-five (45) degree angle at its outside wall leg angled edge 40-E relative to outside wall leg in a vertical plane 30 and outside wall leg in a horizontal plane 50. This outside wall leg angle edge 40-E makes the corner flashing insert easier to place and remove for adjustment. If used as an insert in left lower recessed corner 1200, the corner flashing insert 10 is rotated ninety (90) degrees clockwise from the view in FIG. 4 and inserted into left lower recessed corner 1200 as illustrated in FIG. 12. In the application when rotated ninety (90) degrees clockwise, outside wall leg in a vertical plane 30 serves to cover the lower horizontal wall portion 1060 and the outside wall leg in a horizontal plane 50 serves to cover the left vertical outer wall portion 1020 and the outside wall leg angle 40 covers an integration area.

(25) 3. The second leg of protection is the recessed leg in two planes. Referring to FIGS. 2 and 4, this includes a recessed jamb leg in a vertical plane 60, and a recessed sill leg in a horizontal plane 70. When used as an insert in right lower recessed 1300 as illustrated in FIGS. 10 and 11, the recessed jamb leg in a vertical plane 60 covers the right recessed window opening jamb 1180 at the location of the right lower recessed corner 1300. The recessed sill leg in a horizontal plane 70 covers the recessed opening sill 1120 at the location of the right lower recessed 1300.

(26) When used as an insert in left lower recessed corner 1200, the corner flashing insert 10 is rotated by 90 degrees clockwise and placed in that corner. The parts are numbered in FIG. 5 to show how it would appear when placed in the lower left recessed corner. The parts 30, 40 and 50 have remained the same but they are located at different portions against the window structure.

(27) 4. The third leg of protection is the recessed back leg in a vertical plane 80. The recessed back leg in a vertical plane 80 is preferably set at a forty-five (45) degree angle “A” relative to recessed sill leg in a horizontal plane 70 and a forty-five degree angle “B” relative to recessed jamb leg in a vertical plane 60 and has an angled surface 80-AN. The recessed back leg in a vertical plane 80 covers a portion of lower horizontal buck #1 (2020) but does not extend by a sufficient distance to reach lower horizontal buck #2 (2040). The recessed back leg in a vertical plane 80 functions this way at either corner 1200 and 1300.

(28) 5. The angle and dropped dimension of the recessed back leg in a vertical plane 80 accommodate what is conventionally referred to and called a 1.5 inch reveal (single buck) framing configuration without field modification through its triangular shape and size. Also, as illustrated in FIG. 11, when a sill plan end dam 4000 is installed in a lower right window corner 2250, which is proximate to right lower recessed corner 1300, the dimension and shape of the recessed back leg in a vertical plane 80 does not touch the sill pan end dam 4000 or its angled corner 4100 and therefore optimally integrates the sill pan end dam without field modification in the majority of sill pan applications.

(29) The lower right window corner 2250 is the intersection where window opening sill 3040 and right window opening jamb 3320 intersect. Lower left window corner 2150 is the location where window opening sill 3040 and left window opening jamb 3240 intersect.

(30) 6. FIGS. 2, 4 and 4A provides several important dimensions. The most important dimensions are H-1 which is the distance from the top end of recessed jamb leg in a vertical plane 60-T to the recessed opening sill 1120.

(31) As illustrated in FIG. 11, when the corner flashing insert 10 is installed in a lower recessed corner, the rear surface 70-R of the recessed sill leg in a horizontal plane 70 touches the recessed opening sill 1120. Therefore, for purposes of computing and describing H-1 and H-2 referring only to the corner flashing insert 10 and not using the portions of the recessed window structure 3000, H-1 is also the distance from the top of recessed jamb leg in a vertical plane 60-T to the rear surface of the recessed sill leg in a horizontal plane 70-R; and H-2 is also the distance from the highest vertical point of recessed back leg in a vertical plane 80-H to the rear surface 70-R of the recessed sill leg in a horizontal plane. H-1 is greater than H-2.

(32) The distance by which H-1 is greater than H-2 is numbered H-1EX. The extra distance H-1EX which extends for the entire width 60-W of recessed jamb leg in a vertical plane 60 and the width of outside wall leg in a vertical plane 30-W of corner flashing insert 10 provides extra strength for corner flashing insert 10 and provides more interior surface for sealant material, if desired, while at the same time not impacting the recessed back leg in a vertical plane 80.

(33) 7. As illustrated in FIG. 3, sealant material SM-1 is applied to the rear surface 20-R of corner flashing insert 10, including rear surface 30-R of outside wall leg in a vertical plane 30, rear surface 40-R of outside wall leg angle 40, and rear surface 50-R of outside wall leg in a horizontal plan 50. It is also within the spirit and scope of the present invention for the sealant material SM-1 to be applied to corresponding location on the right vertical outer wall portion 1040 and lower horizontal wall portion 1060. If the corner flashing insert 10 is inserted in the left lower corner 1200, then the sealant material SM-1 can also be applied to the left vertical outer wall portion 1020 and the lower horizontal wall portion 1060. The sealant material SM-1 illustrated in FIG. 3 is for illustrative purposes and can be applied in any desired manner. It is within the spirit and scope of the present invention to apply the sealant material to either or both the outer wall and/or the corner flashing insert, as described.

(35) Similarly, sealant material SM-3 is applied to the rear surface 80-R of recessed back leg in a vertical plane 80 as illustrated in FIG. 3. It is also within the spirit and scope of the present invention for the sealant material SM-3 to be applied to corresponding locations on the lower horizontal buck #1 (2020) and on the right vertical buck #1 (2340). The corresponding locations applied to the left lower recessed corner 1200 also apply. In this case, in addition to applying the sealant to the left of the lower horizontal buck #1 (2020), it would also be applied to the left vertical buck #1 (2220) or right vertical buck #1 (2340) depending upon the placement of the present invention. The sealant material SM-3 illustrated in FIG. 3 is for illustrative purpose and can be applied in any desired manner. It is within the spirit and scope of the present invention to apply the sealant material to either or both the buck areas as described and/or the corner flashing insert, as described.

(36) The identified sealant material SM-1, SM-2 and SM-3 can be the same sealant or different sealants and is/are conventional sealant material used to retain corner flashing inserts to portions of a recessed window structure. It is within the spirit and scope of the present invention to have sealants selected from the group consisting of SM-1, SM-2 and SM-3 or alternatively, to not include any of the sealants.

(37) 8. The corner flashing insert 10 is made out of water impervious material selected from the group consisting of low density polyethylene and high density polyethylene. The corner flashing insert 10 is also transparent. The corner flashing insert 10 is also opaque. It is also within the spirit and scope of the present invention to include other materials not identified herein for the material out of which the corner flashing insert is made.
