9 Claims. (Cl. IUS-16) This invention relates to skylights and particularly to a construction for mounting a prefabricated skylight panel over a roof opening.

In one type of skylight construction which is currently used, a prefabricated panel of double glazed glass units or of a multiplicity of glass blocks is mounted on an elevated curb surrounding the opening in a roof.

lt is an object of this invention to provide a novel frame structure for such a prefabricated panel which is an integral part of the prefabricated panel.

lt is a further object of the invention to provide such a novel panel structure which may be easily mounted on the supporting curb and is adapted to form a weatherproof construction with the roofing materials.

Another object of the invention is to provide such a structure wherein the mounting of the panel on the roof opening may be accomplished quickly and with a minimum of effort.

Fig. 7 is a perspective view of a wire used in the structure shown in Figs. 5 and 6.

Fig. 8 is a fragmentary perspective view of the corner construction in the modified structure shown in Fig. 5.

As shown in Fig. l, a skylight 11i comprises a multiplicity of double glazed units such as glass blocks 11 mounted within a frame 12. The joints between the glass blocks may comprise metal strips and mortar, for example, as shown in the patent to Leuke 2,419,267. The entire panel is mounted on a curb 13 which projects upwardly from roof 14 and surrounds an opening in the roof. The sides of the curb 13 are inclined upwardly and inwardly in order to provide a surface on which the roofing and flashing materials may be laid upwardly into contact with the frame of the skylight panel 1li. The

skylight panel is mounted on the curb in substantially horizontal position, a slight inclination being preferably provided in order to insure drainage of water off the surface of the panel. This inclination may be on the order of one-quarter inch per foot.

Referring to Fig. 3, the frame 12 is preferably made of extruded metal such as aluminum and comprises a generally vertical wall 15. The frame 12 also includes Ylee a downwardly and outwardly extending wall 16 having.

generally the same inclination with the vertical as the tapered surface of the curb 13, a short downwardly extending vertical wall 17 and an inwardly extending horizontal wall 13 on which the glass blocks which are nearest the edge of the panel are mounted. A short rib 1? extends upwardly from the horizontal Wall 18 and is spaced inwardly from the inner edge of the wall 18. This rib 19 serves to position the glass blocks during the fabrication of the panel.

The frame 12 also includes a downwardly and outwardly extending leg 2t) intermediate the ends of the vertical wall 15, the leg 20 having generally the same.

The skylight panel is fabricated at the factory or some.

other suitable place by first positioning the frame members and thereafter arranging the blocks in position with the desired spacing. The joints between the blocks may be similar to those shown in the Lenke patent, and the specific joint does not form a part of this invention.

The joint or connection between the blocks and the frame members is shown in Fig. 3. rfhe block 11 is positioned on the horizontal wall 1S with the edge of the clock abutting against the rib 19. A suitable filler material 25 having high insulating properties is then placed in the space between the block 11 and the frame 12 to a level corresponding with the upper edge of the hook shaped projection 24.

A plastic sealing material'26 adapted to provide a moistureproof joint is then placed over the filler material 25 filling the space between the block 11 and the frame 12. After the filler material and plastic material have set, the panel is ready for delivery to the building or other structure on which it is to be installed.

After delivery to the site and when it is desired to mount the panel on the curb 13, the panel is placed on the curb with the horizontal wall 18 of the frame 12 in contact with the upper surface o-f the curb 13. Small anchor plates 27 are fastened at spaced points along the side of the curb 13 and are adapted to engage the inclined wall 16 of the curb fo-r securing the panel to the curb. The curb 13 may be made of any suitable material into which nails or screws may be driven, for example, wood or gypsum. Roofing material 21 is then placed along the inclined surface of the curb 13 extending between the flat roof 14- and the upper end of the curb. The roofing material may comprise layers of roofing felt cemented together. Flashing material 29 is then applied over the roofing material and extends between the roof and into the area between the inclined leg Ztl and the inclined wall 16 and abuts against the vertical wall 15 of the frame 12.

The flashing may comprise layers of flashing felt cut evenly and cemented together with bituminous plastic cement. The rooting material and hashing material are nailed to the curb at points along the sides of the panel preferably by means of roofing nails 30 driven through dat metal discs 31. A layer of bituminous plastic cement is then troweled over the top layer of the flashing material and a mineral surfaced roofing 32 is placed over the cement. Bituminous plastic cement 33 is placed between the inclined leg 20 and the mineral surfaced roofing 32 and a metal flashing strip 34 is snapped into p0- sition.

"As shown in Fig. 3, the metalA hashing-strip 34 comprises a short vertical wall 3S, an inclined leg 36 extending from the lower end of the vertical wall 35 and aishort lat, projection 37 extending from the upper end ofthe vertical wall 15. The size and-shape of the ashing 34 is such that the llashing may snap into contigous4 relationship with the outer surface of wall 1S and theunder surface of ilat rim 21 of the frame 12. The flashing 34 also includes a short hook 38 extending from` the lower surface of the leg 36 and projecting inwardly below the inclined leg 20 when the lashing strip 34 is in position. After the flashing strip 34 is snapped into position, additional plastic cement is added to point and fill the-'area between the leg 36 and the layer 32.

Metal corner plates 39 are provided and include short vertical portions 40 and inclined portions 41.y Each corn`er` plate 39 is positioned over the tlashing strips 34 at the cornerswith the vertical portions 40 contacting the vertical wall 35 and the inclined portions 39 contacting the inclined leg 36 of the llashing strips34. Small metal screws 42 are then screwed through the inclined portion 41.and the llashing strip 34. Finally, plastic cement is used to llthe space between the corner plates 39 and the kmineral layer 32.

By this construction, a weatherproof mounting is provided for the skylight panel. The novel frame structure is an integral part of the prefabricated panel and the entire panel may be easily mounted on the supporting curb with a minimum of effort.

Where it is desired to mount several skylight panels over a large roof opening, a structure such as shown in Fig. 4 may be used. Structural members 43 are mounted across the opening between the curbs, and an insulated cover plate 44 is positioned over the supports 43. The adjacent prefabricated panels 10 are laid with their edges supported by the insulated cover plate. A ller strip 45 is positioned between the panels l and may be held in position, for example, by a screw 46 extending through the cover. plate 44. Layers of roofing material 47 and flashing material 48 are then applied as in the previous form of the invention, extending between the vertical Walls 15 and overlying the inclined leg 16 and the upper surface of the filler strip 4S. Bituminous plastic cement 33 is placed between-the upper layer of flashing material 48 andthe inclined leg 20 of the frame and the llashing strip 34` is snapped into position. Finally, additional plastic 'cement is forced between the upper layer of ashing material 48 and the leg 36 of the flashing strip 34. By this construction, a multiplicity of panels may be mounted over a large roof opening, the space between adjacent panels providing a drainage trough for the ready drainage of rain or snow.

A modified form of the tlashing strip is shown in Fig.

5. The frame 12 is of identical structure as that shown in Figs. 1 through 4 except that the lip 22 is positioned nearer -to the vertical wall 15, and the flashing strip 34' is provided only with a vertical portion 35 and an inclin'ed portion 36. The llashing 34 is held in position by a' wire49 which is snapped between the 'lip 22' of the frame 12 and the vertical portion 35 of the ilashing 34. As shown in Fig. 7, the wire 49 may have portionsA 50 thereof bent downwardly to form a means for gripping the `wire for ready insertion and removal thereof.jl The corner joints in the -form of the invention shown in Fig.,5 are formed by having the flashing strips bent upwardlyas at 51, and a channel shaped clip 52 is slipped over thejabutting portions Slto form the corner joint (Fig. 8). In addition, the hook shaped projection 24.is eliminated. In Fig. 6 'isshown a structure for mounting a multiplicity.of,panels in.adjacent relationship over a large opening and `utilizing the-modified structure shown in Fig. 5. The panels are mounted in the same manner as shown in Fig. 4.
