DETAILED DESCRIPTION
Referring to the drawing, there is shown a first embodiment of the invention in FIGS. 1-5 and a second embodiment in FIGS. 6 and 7. The first A embodiment includes end domed sections that form an arc to the end walls. In the embodiment of FIG. 6 all domed sections are alike even the end sections but there is provided a separate end glazing or pair of glazings.
In the first embodiment illustrated in FIGS. 1-5, there is provided a continuous domed skylight that generally comprises a dome 10 adapted to engage with a single piece still 12. In FIG. 1 the skylight is shown secured about an opening in a building roof 14. FIGS. 2, 3 and 5 illustrate a wooden curb 16 which may typically have on the inside a finish material 18 which may be a finish plaster or sheet rock, and flashing 20. FIG. 1 also illustrates a flashing 20.
The sill 12 comprises a base 22, a downwardly depending leg 24, and inner and outer walls 26 and 28. Integral channel members 30 and 32 are respectfully connected to the top of the walls 26 and 28. As illustrated in FIG. 2, these channel members are for supporting the respective inner and outer domes 34 and 36. The domes 34 and 36 are provided in sections as illustrated in FIG. 1. The inner dome 34 may be optionally provided. Both of the domes are constructed of an acrylic plastic. The sill 12 is preferably constructed of extruded aluminum.
To provide for the removal of condensation from the skylight, weepholes 27 are provided preferably in the wall 28.
As illustrated in FIG. 2, the sill is suitably anchored to the curb. A minimum of 1/4 inch diameter anchor 29 is employed. There is also preferably provided a continuous mastic material 31 between the sill and the curb. The mastic material 31 is typically applied at the job site by the installer. The anchor 29 may be in the form of a lag bolt with appropriate receiving shield or could be a spike.
FIG. 3 illustrates the structure of the skylight at the intersection between the sill and the intermediate supports. More particularly, an also with reference to FIG. 4, there is provided an intermediate support rib 40 having lower support flanges 41 and 42 and an intermediate support wall 44. The wall 44 supports a centrally disposed member 46 apertured to receive the securing bolt 48. The wall 44 also carries upwardly extending ears 49 and 50. These ears engage and secure respective divider gaskets 51 and 52. The gaskets 51 and 52 extend between the domes. In FIG. 4 the gaskets are illustrated extending on one side between inner and outer dome sections 34A and 36A, and the gasket on the other side extends between dome sections 34B and 36B. It is noted in FIG. 4 that the inner domes rest upon the flanges 41 and 42 and that the inner domes are slightly shorter in the dimension illustrated in FIG. 4. The cap bolt 48 is used for the purpose of securing the dome sections in place. For this purpose there is provided a cap band 54 having oppositely disposed feet 55 and 56 for supporting respective gaskets 57 and 58 and this is the way a weather tight seal is provided between the cap band and the outer dome. The bolts 48 are hex head stainless steel bolts used in conjunction with gasketed stainless steel washers.
As illustrated in FIG. 3, it is noted that the cap band 54 extends slightly beyond the outer dome 36. Upon tightening of the bolt 48 the outer dome 36 is urged against the outer leg of the channel member 32 as clearly shown in FIG. 3. The end of the intermediate support rib 40 illustrated in FIG. 4, is supported in the manner illustrated in FIG. 3. This support includes a support member or post 60 which is secured by means of an elongated bolt 62 from the inner channel member 30 of the sill 12. The member 60 has a slot 64 which is used to position the member 60 relative to the sill. The slot 64 engages with one of the side legs of the channel 30. The aforementioned bolt 62 passes through the member 60 and may threadedly engage with the channel member 30. The member 60 is disposed between the different dome sections and thus does not interfere therewith. However, this member does provide a bottom limiting support for the intermediate support rib 40.
FIG. 5 illustrates the end of the skylight of FIG. 1. This end view illustrates the use of an anchor member 70 which may be an eight penny stainless steel or galvanized common nail extending through downwardly depending flange 24 of the sill. FIG. 5 also illustrates the end construction of the domes. Thus, the domes 34 and 36 have respective end flanges 34F and 36F. A separate retainer is also provided including retainer member 72 having sections 73 and 74. Section 74 rests upon the top of the flanges 34F and 36F. These flanges are sandwiched between the section 74 of the retainer and an extruded gasket 76. The gasket 76 is held below by means of the channel member 32. A similar gasket could also be provided over the channel member 30. The retainer 72 is held in position by means of a retainer closure cap 75 and one or more round head screws 78 engaged with the sill 12 at wall 28.
The other embodiment of the present invention is illustrated in FIGS. 6 and 7. This embodiment of the invention is substantially the same as the embodiment described in FIGS. 1-6. Thus, in the embodiment of FIG. 6, there is provided a sill 112 and associated dome 110 which is of similar construction to the respective sill 12 and dome 10 shown in FIG. 1. The sill 112 is in particular of the same construction as the sill 12. In the first embodiment, the dome sections may be identical to those shown in the second embodiment at least for the three center sections. In the first embodiment the end sections taper downwardly or are arcuately disposed downwardly toward the end sills. However, in the embodiment of FIG. 6 it is noted that five substantially identical dome sections can be provided with the end dome sections having the structure of FIG. 7 associated therewith. Thus, as illustrated in FIG. 7 there are provided a pair of dome including inner dome 134 and outer dome 136. Again, this skylight is for use about an opening in a building such as the roof 114 illustrated in FIG. 6. A wooden or the like curb 16 in part defines the opening and has on its inner side a finish board 118 which may be plaster or sheet rock. A flashing 120 is also used and is illustrated in both FIGS. 6 and 7. FIG. 6 also illustrates the use of the cap band 154 which may be identical to the cap band 54 as shown in the first embodiment. Also, the complete structure shown in FIG. 4 relating to the intermediate support rib may also be employed in the embodiment illustrated in FIGS. 6 and 7. Because much of this structure is identical to that shown in FIGS. 1-5 it is not repeated in FIGS. 6 and 7. The primary difference in FIGS. 6 and 7 relates to the end structure illustrated in FIG. 7.
Thus, in FIG. 7 there is illustrated a unique end sill construction including sill 90 having a base 91, downwardly depending wall 92, upwardly extending wall 93, and a channel member 94. There is preferably provided a weep hole 95 in wall 93. The base 91 of the sill 90 is secured to the curb by means of an anchoring member 96. A continuous mastic 96 is also provided, applied at the job site by the installer, between the sill and the curb. An extruded channeled gasket 98 is fitted within the channel member 94 and is adapted for supporting the vertically disposed end glazing panels 100 and 101.
The structure illustrated in FIG. 7 also includes an extruded vertical end rib 102 and extruded vertical end cap 103. The end rib 102 is very similar in construction to the intermediate support ribs. A bolt 104 secures the extruded vertical end rib to the extruded vertical end cap. The vertical end rib 102 has a lower flange 105 and a side ear 106. A gasket 107 similar to the aforementioned gaskets 51 and 52 is disposed between the domes 134 and 136. The lower dome 134 rests upon the flange 105.
The extruded vertical end cap 103 includes at one side a channel member 108 for holding the extruded gasket 109. The gasket 109 is channeled to receive the top arcuate side of the vertical glazing panels 100 and 101. The other side of the vertical end cap 103 has a foot 111 supporting a gasket 113 similar to the gaskets 57 and 58 illustrated in FIG. 4.
Having now described a limited number of embodiments of the present invention, numerous other embodiments are contemplated as falling within the scope of this invention.
