Nov. 26, 1963 M. WASSERMAN SKYLIGHT AND CEILING LIGHT CONSTRUCTION Filed 001;. 22, 1954 Izzy: haw/5555i i W United States Patent 3,111,786 SKYLIGHT AND CEILING LIGHT CONSTRUCTIGN Max Wasserman, Erookline, Mass, assignor by mesne assignments, to American Cyanamid Company, New York, NY a corporation of Maine Filed Oct. 22, 1954, Ser. No. 463,393 Claims. (Cl. 5016) The present invention relates to an improved combination skylight and ceiling light construction, and also to an improved frame construction for supporting plastic skylight and ceiling domes.
it is an object of the present invention to provide a combination skylight and ceiling light structure in which an extruded aluminum frame supports and secures in a unitary fashion a pair of plastic dome structures formed with peripheral outwardly extending flanges, with one of the domes functioning as a skylight and the other dome functioning as a ceiling light transparent member.
It is also an object of the present invention to provide a water tight unitary combination skylight and ceiling light of a domed construction in which the ceiling dome is secured beneath the skylight dome to the same frame construction which supports the skylight dome.
A still further object of the present invention is to provide a supporting frame for a pair of plastic domes which may readily be formed of extruded aluminum sections and which is adapted to be fitted over curbings of skylight openings.
These and other objects and advantages of the present invention will be more clearly understood when considered in connection with the accompanying drawings in which:
FIGURE 1 is a cross sectional vertical view of the invention FIGURE 2 is a fragmentary cross sectional vertical view of a modification of the invention.
Referring particularly to FIGURE 1, there is disclosed a supporting frame generally designated ll, formed of four extruded aluminum sections joined at miter-ed ends to form a rectangular frame. Each aluminum section has a cross section in which there is a covering member 2-, adapted to fit over a wooden curbing 3 of a skylight opening. The cross section of the covering member 2, may be inclined downwardly toward its outer edge by forming shoulder or ridge elements 4 and 5 along its lower surface, with the shoulder element 4- slightly thicker than the ridge element 5. On the outer edge of this covering element 2, is formed a downwardly extending flange 6, which is adapated to extend downwardly beyond the wooden curbing 3. A gutter is formed by the L shaped member 7, which has its lower transverse leg 9 extending outwardly from the downwardly extending flange 6 and its upwardly extending leg 8, parallel thereto.
On the inner end of the covering frame 2, are the downwardly extending flange 1i and upwardly extending flange 11, as well as an inwardly extending flange 12, which is substantially horizontal and preferably in the same plane as the covering element 2. The frame is secured to the curbing by a series of screws or nails 13 which pass through holes in the downwardly extending flange 1t) and into the wooden curbing. The upwardly extending flange 11 acts as a gutter member in keeping condensation from seeping into the skylight opening. Supported on the inwardly extending flange 12, is a plastic ceiling dome 14A, of transparent or translucent plastic material. This dome is provided with a peripheral outwardly extending flange '15, which rests upon and is coextensive with the inwardly extending flange 12. The dome 14, is held in position by a series of lock clips 16, which clip on to the upwardly extending flange 11 and 3,1 l 1,786 Patented Nov. 26, 1963 have an inwardly extending section 17 positioned over the ceiling dome 14.
Supported on the cover member 2, is a plastic skylight dome 1 8 of translucent or transparent material. This dome is also provided with an outwardly extending peripheral flange 19, 19 substantially coextensive with a portion of the covering member 2, and spaced from it by a gasket element 219. The dome 18, is secured down by an angle member generally designated 21, having one leg 22', positioned over the flange 1d and spaced from it by the gasket element 23. The other leg 24 of the angle member 21 extends downwardly and is in face to face relation along a portion of its length with the upwardly extending leg 8 of the member 7. This angle member 21 is secured to the gutter member '7, by a screw 25, passing through the angle member 21, and the leg 8, of the gutter member '7. This screw 25, may be secured in position by a tinner-rnan nut 26.
In this construction, the ceiling dome 14, may be of somewhat thinner gauge than the skylight dome 18, as it is not subject to the same weather conditions as is the skylight dome 18. The ceiling dome, further preferably has a smaller dome rise than does the skylight dome 18, thus forming a substantial air space between the two domes which acts as insulation.
A modification of this invention is illustrated in FIG- URE 2, in which the extruded aluminum frame is formed of sections having a cross section as illustrated in that figure. The covering section 27 extends outwardly beyond the curbing 28 and terminates in a downwardly extending flange section 29. On the inner edge of the covering member 27, is formed an inwardly extending flange 30, and an upwardly extending flange 31. The flange 3 1 acts as a gutter element to keep moisture formed on the skylight dome 32, from seeping into the skylight opening. The inwardly extending flange 30 supports the ceiling dome 33, at its peripheral outwardly extending flange 34. The dome 36 may be secured in position by a series of lock clips 35, which fits over the upwardly extending flange 31. The skylight dome 32, is secured in position by the angle member 37, which has one leg 3-8 extending over the peripheral outwardly extending flange 39 of the dome 32 and the other leg 4%) extending downwardly and substantially parallel to the downwardly extending flange 29. The flange 39 of the dome may be spaced from the covering member 27, by the gasket 41, and from the leg 38 of the angle member 37 by the gasket d2. The entire structure is secured to the curbing of the skylight, and the dome 32. is secured to the covering member by a screw 43 which passes through the downwardly extending flange 40' and the downwardly extending flange 29 and into the side of the curbing 28. A recess 44 may if desired be provided in the downwardly extending section 40 of the angle member 37 at the point where the screw 43 passes through it. This recess will form a more snug fit and thereby a more watertight fit with the downwardly extending flange 29 and thereby help prevent the ingress of water. It should be noted the downwardly extending flange 40 preferably extends beyond the downwardly extending flange 29, and is flared outwardly at its lower end 45.
In both modifications, the gasket elements supporting the skylight dome should not be continuous all along the covering member, but should be provided with small transverse passages preferably at the corners to permit water to drain out. In the modification as shown in PEG- URE 2, the recess 44 should not be so tight as to prevent water draining from the inside of the skylight to pass outwardly from between flanges 4t? and 2%.
This invention may be modified in a number of ways including but not limited to a combination skylight and ceiling dome in which the supportng frame instead of being rectangular in form is circular, and supports ceiling domes and skylight domes which have a peripheral circular edge.
