Aug. 1, 1961 N. L. SANDIN ROOF DRAINING SINKS Filed Dec. 30, 1957 wn-wme /V/LS LENNFIRT Saw/v Unit 2,994,433 ROOF DRAINING SINKS Nils Lennart Sandin, Lund, Sweden, assignor to Frans Harry Karlsson, Lund, Sweden Filed Dec. 30, 1957, Ser. No. 706,214
2 Claims. (Cl. 210-163) The present invention generally relates to roof draining equipment, and more particularly to new and useful improvements in roof draining sinks of the type comprising a tubular duct having a conical top section and provided with a perforate screening member or sieve.
The invention has for its object to provide a roof draining sink of the type referred to in which an absolutely effective tightness between sink and roof covering will be provided for, and which is applicable to roof constructions of different kinds and with different angles of slope.
The invention is mainly characterized in that the sieve is carried by a sealing ring which rests on abutments provided on the internal wall surface of the top section and is so constructed and dimensioned as to cause an annular clearance to extend peripherally around the sink between said ring and said top section, said clearance being adapted to have clamped therein a portion of a roof covering material, such as, for instance, conventional roofing cardboard, plastic foil or so-called surfacing cardboard. Where the roofing material proper is very rigid in nature, there may be fastened thereto around the sink any suitable material, such as plastic foil, having greater ductility or flexibility than the roof covering material proper, said plastic material being clamped with its inward edge portions in the clearance between the sealing ring and the top section. The use of a sealing ring in association with a plastic foil will provide for a perfectly reliable interconnection between the sink and the roof covering.
Further features and details of the invention will appear from the following description with reference to the accompanying drawing which illustrates, by way of example, and diagrammatically, two different constructional forms of a roof draining sink embodying the present invention, and in which:
FIG. 1 is a sectional elevation of a roof draining sink in which the angle between the sink axis and the roof profile differs from 90.
FIG. 2 is a sectional elevation of a roof draining sink in which the angle between the sink axis and the roof profile is 90.
FIG. 3 on a larger scale illustrates a detail of the sink arrangement.
In the drawing, numeral 34 designates the roof construction proper, this construction consisting in this case of wood. The roof training sink encased in this roof construction-and the axis of which is designated by 35-consists of a cylindrical duct 36 having a conical top section which is provided interiorly with a short cylindrical and coaxial offset portion as well as with three abutment members 37 uniformly spaced circumferentially of the sink. Seated on these abutments 37 is a sealing ring 38 which is so shaped and dimensioned relative to the sink as to form between the same and the cylindrical offset portion of the top section an annular clearance extending throughout the periphery of the sink (see FIG. 3). Numeral 39 designates a conventional sieve seated on the sealing ring and having a throughflow area at least twice the outlet area of the sink.
the same around the draining'sink a more ductile or flexible plastic foil or sheet 40 the inner edge portion of which is clamped in said annular clearance.
The abutments 37 can also be utilized, in a manner known per se, for the mounting of a provisional drain in the form, for instance, of a gutter pipe (not shown in the drawing) in order to drain off rain water during the building period. Such gutter pipe has afiixed thereto three pieces of wire 42 the upper ends of which are secured in recesses 43 in corresponding ones of the abutments 37, or may be formed with loops to be fastened about the abutments.
In the case of wooden roof structures, the top section of the drainage sink could alternatively be provided with a peripheral, conical adapter ring 44 having nail holes 45 fastening the sink in place. Such a ring also provides for an improved connection between the sink and the roof structure.
The sealing ring 38 may further have secured to it a resilient clamping ring 46 for retaining the sieve 39 in place.
The roof draining sink is installed in the manner:
After securing the sink to the roof structure, a sheet of plastic 40, for instance, is placed on the roof surface surrounding the sink and is glued onto the same. The plastic sheet is glued (or warmed up to its sticky state) on its underside and is clamped in place by means of the sealing ring 38. If the sieve is to be fixed in position the clamping ring '46 is assembled with the sealing ring 38 before depressing the latter onto its seating. The sieve may be securely clamped in place, if desired.
What is claimed is:
l. A roof draining sink comprising a duct including, taken in order towards its upper end, a cylindrical tubular portion, a first outwardly flared frusto-conical portion, an annular seating portion having a cylindrical infollowing her surface coaxial with the tubular portion, and a second outwardly-flared frusto-conical portion, a plurality of abutments spaced about the internal surface of the first outwardly-flared portion, and a solid continuous clamping ring having a cylindrical periphery of slightly less diameter than the internal diameter of the cylindrical inner surface of the seating portion and of less axial length than said inner surface, said clamping ring serving to define with the seating portion, when supported on the abutments, a peripheral annular gap in which roof sheeting of greater thickness than the width of the gap may be disposed, whereby forcing the clamping ring axially and concentrically into the cylindrical seating portion compresses the sheeting in said gap and serves to clamp it to the sink.
2. The combination of a roof-draining sink and roof sheeting material sealed thereto, wherein the roof-draining sink comprises a duct including, taken in order towards its upper end, a cylindrical tubular portion, a first outwardly-flared frusto-conical portion, an annular seating portion having a cylindrical inner wall surface coaxial with the tubular portion, and a second outwardly flared frusto-conical portion, a plurality of abutments spaced about the internal surface of the first outwardlyflared portion, and a solid continuous clamping ring having a cylindrical periphery of slightly less diameter than the internal diameter of the seating portion and of less axial length than said seating portion, said ring serving when seated on the abutments to define a gap with said seating portion, and a sheet of resiliently-compressible roof-sealing material having a circular aperture therein, said sheet being disposed to cover the second outwardlyflared portion and extending radially outwards therefrom, said sheet having its edge portions adjacent the aperture therein disposed coaxially within the cylindrical seating portion, the clamping ring being disposed concentrically within the seating portion, the natural thickness of the sheet being slightly greater than the width of the gap between the clamping ring and the seating portion, whereby said sheet is compressed between the clamping ring and the seating portion and is thereby clamped to the sink.
