Claims20
In a combination of a roof structure with an adjustably extensible roof drain receptacle comprising:
- (a) a roof structure having means defining an opening, said roof structure including a roof deck having an upper surface with roofing materials thereon to provide said roof structure with an upper surface;
- (b) a drain pipe substantially coaxial with the opening of said roof structure and extending downwardly therefrom;
- (c) a one piece drain body in the opening of said roof structure and having an open top for receiving water to be drained from the upper surface of said roof structure, said drain body having a bottom outlet directly connected in a leakproof manner to said drain pipe;
- and
- (d) extension means disposed about said drain body and attached to the upper surface of the roof deck of said roof structure and to the periphery of said drain body for supportingly mounting said drain body in the opening of said roof structure, said extension means being vertically adjustably extensible to position the open top of said drain body at a proper water receiving position relative to the upper surface of said roof structure.

- (b) a drain pipe substantially coaxial with the opening of said roof structure and extending downwardly therefrom;
- (c) a one piece drain body in the opening of said roof structure and having an open upper end for receiving water to be drained from the upper surface of said roof structure, said drain body having a bottom outlet sealingly connected directly to said drain pipe, said drain body having a flange which extends substantially laterally therefrom with said flange having a downwardly facing surface;
- and
- (d) adjustable extension means disposed about said drain body and mounted between the upwardly facing surface of the roof deck of said roof structure and the downwardly facing surface of said flange of said drain body to mount said drain body in the opening of said roof structure, said adjustable extension means being adjustable for positioning the open upper end of said drain body at adjustably selectable distances above the roof deck in a proper water receiving relationship with the upper surface of said roof structure.

In a combination of a roof structure with an adjustably extensible roof drain comprising:
- (a) a roof structure having means defining an opening and including a roof deck having upper and lower surfaces with roofing materials thereon to provide said roof structure with a top surface;
- (b) a drain pipe substantially coaxial with the opening of said roof structure and extending downwardly therefrom;
- (c) a one piece drain body in the opening of said roof structure and having an open upper end for receiving water to be drained from the top surface of said roof structure, said drain body having a bottom outlet sealingly connected directly to said drain pipe and having a flange extending substantially laterally therefrom, said flange having a downwardly facing surface and disposed so as to circumscribe the open upper end of said drain body;
- (d) a deck flange mounted on the upper surface of the roof deck of said roof structure and having an axial bore which is substantially coaxial with the opening of said roof structure;
- and
- (e) an adjustable collar mounted in the axial bore of said deck flange and attached to the downwardly facing surface of said flange of said drain body so that said adjustable collar is coaxial with said drain body, said adjustable collar being axially movable in the axial bore of said deck flange to adjustably position the open upper end of said drain body proximate the top surface of said roof structure.
