DETAILED DESCRIPTION OF THE DRAWINGS
A perspective view of a pipe boot assembly 2 attached to a roof 4 of a building such as a house is shown in FIG. 1. Pipe boot assembly 2 illustratively comprises a base flashing 6, inner sleeve 8, outer sleeve 10 telescopingly engaged with inner sleeve 8, and an interlocking cap 12 having an opening 14 disposed thereto to accommodate the opening of a shrouded plumbing pipe. As is evident, the telescoping engagement between inner and outer sleeves 8 and 10, respectively, make it possible for pipe boot assembly 2 to shroud pipes that extend various lengths from roof 4.
An exploded view of pipe boot assembly 2 is shown in FIG. 2. In this view, base flashing 6 includes a back flange 16 configured to fit under shingles of a roof. Front corners 18 and 20 are sloped and bend inward to increase the slope of the pitch pipe flashing. Alternatively, they may be bent outward to decrease the pitch of the pipe flashing. In an illustrative embodiment, raised nail embosses are formed along the periphery of flashing 6 to assist with its install. Opening 24 includes a flange 26 formed around its periphery through which the plumbing pipe may extend. Inner sleeve 8 fits to flange 26. It is appreciated the seal between inner sleeve 8 and flange 26 may be water tight. Outer sleeve 10 fits over inner sleeve 8 in a telescoping manner. Openings 28 and 30 are disposed through sleeves 8 and 10 to form the passageway that receives the extending plumbing pipe. Outer sleeve 10 may be moved in directions 32 and 34 to create the telescoping adjustment to accommodate plumbing pipes of varying heights, as well as account for roof expansion and contraction. Interlocking cap 12 may be configured to attach to outer sleeve 10, as well as fit onto the top of the plumbing pipe to complete the shrouding of same. It is appreciated that despite cap 12 being attached to outer sleeve 10, it is not otherwise affixed to inner sleeve 8 to allow the vertical movement in directions 32 and 34. It is further appreciated that cap 12 and other structures may be made of galvanized steel such as 26 gauge G-90 galvanized steel. The caps may also be made in a variety of sizes to correspond to the standard sizes of PVC or other plumbing pipes.
A perspective partially exploded view of pipe boot assembly 2 is shown in FIG. 3. This view depicts how PVC plumbing pipe 36 may be disposed through base flashing 6 and inner sleeve 8 through opening 28. Outer sleeve 10 with cap 12 attached thereto may then be placed over plumbing pipe 36 to shroud the same. A pipe seat 38 may be formed about the periphery of opening 14 in cap 12 to receive end 40 of plumbing pipe 36 to support both outer sleeve 10 and cap 12. It is appreciated from this view how by engaging this operation with outer sleeve 10 being placed over inner sleeve 8, plumbing pipe 36 may be any variety of lengths, yet still remain shrouded.
A perspective cut away view of pipe boot assembly 2 shrouding plumbing pipe 36 is shown in FIG. 4. This view demonstrates how pipe 36 extends upward through openings 24, 28, and 30 in base 6, inner sleeve 8, and outer sleeve 10, respectively. Flange 26 is also shown attached to inner sleeve 8. This view also depicts how outer sleeve 10 may be placed over inner sleeve 8 and moved in directions 32 and 34 to shroud pipe 36. The overlap between inner and outer sleeves 8 and 10, respectively, offers a variety of heights that pipe boot assembly 2 may shroud. A barb or prong 42 may be formed in or otherwise be part of pipe seat 38 to assist attaching cap 12 to pipe 36. Illustratively, cap 12 may be rotated in direction 46 so that barb or prong 42 may dig into the inside of the pipe to secure the same on to the pipe boot assembly 2. Conversely, to illustratively remove pipe boot assembly 2, cap 12 may be rotated in the opposite direction and then allows outer sleeve 10 with cap 12 may be lifted off.
Perspective and elevational cross-sectional views of inter locking cap 12 is shown in FIGS. 5A and B. Prongs 42 and 44 are shown extending outwardly from inner wall 48 of pipe seat 38. Between inner wall 48 and outer wall 50, a channel 52 is formed that receives the end 40 of pipe 36. Prongs 42 and 44 extend into channel 52 so as to cut a groove or thread into the wall of pipe 36 to secure cap 12 thereto. This attachment means is like forming a thread, similar to threads on a fastener threading a hole. Cap 12 may be rotated in a first direction to attach to pipe 36, and then rotated in the opposite direction to attach from pipe 36. In addition to the prongs, inner and outer sidewalls 48 and 50 taper away from the center of channel 52 in order to help with pipe alignment and the channel. Tapers 54 and 56 are illustratively 5 degree tapers on each side to help guide pipe end 40 into channel 52. In addition, top surface 58 of cap 12 is sloped downward for water drainage. The slope may illustratively be about 6 degrees, as indicated by reference numeral 60 in FIG. 5B.
FIGS. 6 through 10 demonstrate how the pipe boot assembly can be sized to accommodate plumbing pipes of varying diameters. Typically, these plumbing pipes have standard sizes such as 1½, 2, 3, and 4 inches. As shown in FIG. 6A through D, a plurality of pipe boot assemblies—62, 64, 66, and 68 are shown. The principal distinction is in their caps 72, 74, 76, 78, respectively. As shown in FIG. 6A, cap 72 has a pipe seat 82 configured to accommodate an illustrative 1½ inch diameter pipe. Similarly, cap 74 includes pipe seat 84 sized to accommodate a 2 inch pipe; pipe seat 86 of cap 76 accommodates a 3 inch pipe; and lastly seat 88 of cap 78 is sized to receive a 4 inch pipe. It is appreciated that the telescoping sleeve, such as 8 and 10 previously discussed, may be used with any of these caps. In addition, these caps may be made of 26 gauge G-90 galvanized steel.
Pipe boot assembly 62 shown in FIGS. 7A and B demonstrates how a 1½ inch diameter pipe 102 may fit into seat 82 of cap 72. In similar fashion, pipe boot assembly 64 shown in FIGS. 8A and B demonstrate how pipe 104 is seated in seat 84 in cap 74. The views in FIGS. 9A and B include pipe boot assembly 66 which show how pipe 106 fits into seat 86 of cap 76. And lastly, pipe boot assembly 68 shown in FIGS. 10A and B demonstrates how pipe 108 fits into seat 88 of cap 78. It is appreciated that these pipe boot assemblies shown in FIGS. 6 through 10 may include the same prongs as those described in the first embodiment and can be assembled and disassembled in the same manner as discussed as well.
Although the present disclosure has been described with reference to particular means, materials and embodiments, from the foregoing description, one skilled in the art can easily ascertain the essential characteristics of the present disclosure and various changes and modifications may be made to adapt the various uses and characteristics without departing from the spirit and scope of the present invention as set forth in the following claims.
