DESCRIPTION:
BRIEF SUMMARY
FIELD OF INVENTION
This invention relates to a skylight frame and panel assembly for mounting in an aperture in a sloping roof.
This disclosure incorporates by reference U.S. Pat. No. 4,589,239 dated May 20, 1986.
BACKGROUND OF INVENTION
This invention represents improvements in the disclosure set forth in U.S. Pat. No. 4,589,239 which shows the basic concept of the skylight. Production considerations and the desire to reduce costs and simplify installation of the skylight in the roof aperture combined to create problems in how best to utilize the teachings of U.S. Pat. No. 4,589,239.
SUMMARY OF THE INVENTION
The foregoing considerations have led to the development of an improved structure retaining the basic teachings of U.S. Pat. No. 4,589,239 but permitting improvements in ease of production, installation in a roof aperture, reduction in costs and further safeguards against the entry of moisture through or around the skylight. This is accomplished by constructing the skylight frame of header, side and bottom rails having different lengths but uniform heights at their ends whereby a plurality of different size skylight frames can be produced with but a few different length rails. Exposed surfaces and gaps are covered by vacuum formed plastic coverings which also serve to define skylight panel receiving channels and seal seats. Roofing nail impervious barrier strips protect skylight panel receiving channels from roofers inadvertently nailing thereinto, and the translucent skylight panel is held in its trough-like shape by an intregal flange at one end of the panel. The panel is held is place by a releasable fastener disposed between the flange and the skylight frame.

BRIEF DESCRIPTION OF THE PREFERRED EMBODIMENTS
As shown in FIG. 1 the improved skylight frame and panel assembly comprising a generally rectangular, box-like frame 20 having header 22, sides 24 and 26 and bottom rails 28 which are secured together at their corners by fasteners 30 and adhesive 32 (see FIG. 5). The frame members may be formed of plastic or other suitable materials, or by a combination of wood and plastic. As shown in FIGS. 3, 5, 6 and 8, the frame members comprise a wooden structural part identified with a suffix identification (a) which is covered by a formed plastic layer identified by the suffix identification (b). This plastic layer may be vacuum formed to mate or nest with the underlying wooden frame, and covers and conceals the wood protecting it from weathering and also providing an attractive and tough surface that may be painted if desired. ABS polymers will be suitable for this purpose. The frame is received in a roof aperture provided in the roof structure. The aperture may be framed up between roof rafters, one of which shown in phantom outline at 34 in FIG. 3, and the skylight frame is hung in the aperture upon an angle bracket 36 (see FIGS. 1, 2 and 6) and the projecting ends 38 and 40 of the bottom rail 28. The angle bracket 36 is secured to the header by fasteners 42 and overlies the roof boards 44 adjacent the header end of the aperture and is nailed thereto as shown. The project
