The present invention is a continuation-in-part of my copending application, Serial No. 366,648, filed July 8, 1953, for Skylight, and now abandoned. In Figures 1-3 of the drawings, the numeral 10 designates the skylight mounting frame construction in its entirety.
This construction consists of a skylight panel supporting frame 12 and a skylight clamping or attaching frame 14.
i vThe supporting frame 12 is constructed in such a mannet. that it eliminates the necessity for a curb customarily utilized around skylightopenings for attachingthe skylight covering panel thereto. Each base frame member of 'the supporting frame 12 is shaped in cross-sectional configuration like an I-beam, includingavertical web 16, top plate 18 and bottom plate 20; As will 'be noted in the drawings, the top and bottom plates or flanges 18 and 20 are horizontally disposed or. perpendicular to the vertical web 16 and are integral therewith. Further, the plates or flanges 18 and 20 are attached to the web 16 intermediate their edges.
Bottom plate 20 is in the nature of a fiat, relatively wide base portion 22 having a downturned flange or skirt 24' formed on the inner edge thereof, the base:portion 22 resting. flat ag'ainst'the top surface of a roof or the like 26 with the downturned flange 24 abutting the side edge of the roof defining the skylightopening to position the supporting frame around the periphery of this. opening. The'upper surface of the base'portion 22 extending around the periphery of the supporting frame outside of the confining areaof the web 16 is provided base portion 22 in abutment with the roof surface and the-downturned flange in abutment with the side edges of Y the roof surface defining the skylight opening. Then, the
top surface of the base portion 22 including the notches 28 are coated with a suitable roof sealing composition,
and the roofing paper 30 'or'the like overlies the top surface of the base portion 22 and is sealed thereto, the notches 28 providing a water-tight seal when filled with the sealing composition.
The top plate or flange 18 forms the web or bottom of a channel having an upturned inner side flange 32 and an upturned outer side flange 34. The free edge portion of the outer side flange 34, is upwardly and inwardly bent to overlie a portion of the web 18 of the outer side flange 74.
In addition to'its supporting -function, the channel consisting of the web 18 and flanges 32 and 34 comprises a condensate gutter, outer side flange 34 being provided with longitudinally spaced apertures at the juncture of this flange to the web 18 to drain condensate from the gutter onto the roof surface 30.
The portions of the top plate 18 and the bottom plate 20 extending inwardly from the web 16 of the 'I-member provide a hollow space for the reception of insulating panels, such as that shown at 42 in Figure 2, if desired.
The attaching frame 14, by means of which the corrugated skylight panel 38 is clamped onto the upper inturned flange portion 36 of the supporting frame 12 spacedly surrounds the supporting frame 12.
This attaching frame is, as shown in Figures 2 audit, in the shape of an angle iron in cross-section, including first and second right angularly related legs 46 and 48. Leg 46 lies parallel to the outer side flange 34 of the channel top plate 18 and is spaced therefrom. Fasteners 50 join leg 46 to the outer side flange 34 and spacing members or collars 52 on each fastener 50 maintain the leg 46 in fixed, spaced relation to the outer side flange 34.
Leg 48 extends inwardly transversely of leg 46 and overlies the inturned flange portion 36 and clamps the edges of the skylight panel 38 within the space between the second or transverse leg 48 and the inturned portion 36 of the side flange 34.
At the juncture of the legs 46 and 48, the angle members comprising the attachment frame 14 is formed with an-enlargement in the form of an undercut triangular block 54 which serves as an abutment stop for the peripheral edges of the skylight panel 38 to space them from the first leg 46 of the attachment frame. The depth of this abutment stop which is formed integrally with the frame '14 'issubstantially equal to the space between the leg 46 of the attachment frame andthe outer :side flange 34 of the supporting frame in order to ensure proper drainage from the surface of the skylight panel 38 which, as shown in the drawings, is in the form of a corrugated translucent, preferably plastic plate. This constructionserves to automatically space the peripheral edges of the skylight panel from the leg 46 of the attachment frame, permitting free drainage in the space between the attachment frame and the supporting frame while comprising an extremely strong panel.
'In the modified skylight structure 56 as shown in Figures 4-6 of the drawings, provision is made for weather stripping the corrugated skylight dome or panel 38 against thepassage of air between the dome and its supporting frame.
The supporting frame is designated .by the numeral 58 and the skylight panel attaching frame by the numeral '60. The attaching frame 60 is identical .to the previously described attachingframe andis, as shown in Figures 5 and 6, in the shape of an angle iron in crosssection, including first and second right angularly related legs 62 and 64, the angle between the legs being partially occupied by an integrally formed, triangular-shaped abutment block or stop 65 for the skylight panel 3,8.
The supporting frame 58 distinguishes from the previously described supporting frame 12 although being of substantially the same cross-sectional configuration, namely, that of .an I beam. Each frame member consists of a vertical web 66, top flange or plate 68 and bottom flange or plate 70.
The bottom plate 70 and the web 66 are identical to those of frame 12.
The top plate 6:3,form the bottomor web eta channel ha i an p ned n -s d ge 2 and a ptu n d The free edge portion of the outer side flange is upwardly and inwardly bent forming a lip or inclined flange 76 overlying a portion of the web of channel 68. The free edge portion 78 of the lip 76 is disposed substantially parallel to'the web of the channel and spaced, vertically extending legs 80 rising from the free edge portion 78 form a sealing strip receiving channel.
A resilient strip of sponge rubber or other suitable material 82 is received between the legs 80 and projects thereabove around the supporting frame.
Thus, the skylight panel 38 rests directly on the sealing strip 82 which readily conforms to the undulations of the corrugated panel and prevents the ingress of air between the panel and the supporting frame.
With either form of the invention as above described,
where the panel is domed as shown, there is no necessity for spacing the leg 62 of the attaching frame 60 from the flange 74 of the supporting frame 66 on the sides of the supporting frame parallel to the direction of the corrugations on the panel 38 since no drainage will occur on those sides, the leg 62 and flange 74 being shown in abutment in Figure 5.
The skylight supporting frame, as described, provides a'simple and effective means of mounting the skylight panel over a skylight opening which necessitates the formation of no surrounding curb for the skylight opening, which assures proper drainage onto the roof from the skylight panel and proper drainage of condensate forming underneath the skylight panel, and which is capable of simple and quick attachment to a roof surrounding the skylight opening.
In the modification of Figs. 7 and 8 a construction'suitable for mounting on a conventional curb comprises in the mounting frame 110, a curb frame 116 and a frame 118 for retaining between this frame and the curb frame 116 the dome or panel 114.
The curb frame 116 provides a continuous gutter 120 of channel shape including bottom or web 122 and inner and outer upstanding flanges 124 and 126, respectively. 'Integrally depending from the lower surface of the web 122 between the inner and outer flanges 124 and 126 is an apron 128 "which extends throughout the length of the curb frame 116. The lower surface of the web 122 between the inner flange 124 and apron 128 rests upon the top of the curb 112 while the apron 128 itself lies flat against the outer side surface of the curb 112. Suitable fasteners 130 secure the apron 128 to the curb 112 and constitute the means for securing the curb frame 116 to the curb 112.
The inner flange 124 extends upwardly at an obtuse angle to the web 122 of the channel shaped condensate gutter to increase the condensate collecting area of the condensate gutter.
The outer flange 126 of the condensate gutter 120 in the embodiment being described rises vertically from the -web. 122 and has its upper flange portion inwardly turned as "at 132 to overliea portion of the web .122. In this embodiment the web 122 and the outer flange126 overhang the curb somewhat.
Weep holes 134 are provided in the web 122 between the'outer flange 126 and the apron 128 to allow'con- ,densate within condensate gutter 120'to drip down over the outer surface of the apron 128. The bottom edge ofthe apron 128 is out-turnedas at 136 to provide a 'dripflange todirect thecondensate away from the-curb 112 to fall upon the roof.
Theretaining frame 118 spacedly surrounds thecurb .frame 116 and is generally .L-shaped in cross-sectionincluding a first vertical leg 138 and a second transverse leg .140.
The first leg 138 lies parallel to and spaced outwardly fromzthe outer flange .126 and is secured to the outer flange 126 by means of preferably self tapping screws 142. Spacers, 1441 provided on these screws 142 areinterposed between the outer flange 126 and the first leg 138 ofthe retainingframe 118 to maintain these members in spaced relation to one another.
The second or transverse leg'140 of the retaining frame '118 overlies the inturned flange portion 132 extending upa -tea e wardly from the outer flange 126 whereby the edge portions of the dome'or panel ll tare clamped between the leg 140 and the flange portion 132. The spacing between the first leg 138 and the outer flange 126 provides a convenient liquid removing passage throughout the periphery of the supporting frame 110 to carry away that water which'would collect between the-edges of the panel or dome 114 and the retaining frame 118, The drip flange 136 on the bottom edge ofthe apron 128 will serve also to direct this discharge from the frame 110 away from the curb'112.
The dome or panel 114 is preferably of corrugated plastic which may be completely transparent or tinted to any desired degree of opacity. The shape of the dome or panel 114 may be flat, arched or hemispherical as desired. When the skylight panel 114 is arched as shown in Figs. 1, 2, 4 and 6, the length andcurvature as well as the angular relation 'of the first and second legs 138 and 140 of the retaining frame ,118 of Figs. 7 and 8 are varied accordingly.
Where the weight of the dome panel 114 warrants,
channels for directing rain water from the dome through i the space between'the-leg 138 of the retaining frame 118 and the flange 126 of the curb frame 116. Any overflow of rain water' or condensation on the'panel will go into the condensation gutter 120 and will be carried out through the weep holes 134.
From the foregoing, the construction and operation of the device will be readily understood and further ex planation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claims.
