23,038/ 64 p 2 Claims. (Cl. 61-14) ABSTRACT F THE DISCLOSURE A gutter union comprising a seating portion adapted to receive therein adjacent ends of plastic guttering, the seating portion having a spout opening from the central portion thereof. The ends of the seating portion are of greater radius than the central portion and have a sealing gasket disposed therein. The adjacent ends of two lengths of guttering are held in the ends of the seating portion by means of inwardly extending lips on opposite sides thereof, one lip of which is also provided with a downwardly extending ear. The inner walls of the seating portion have xed stop pins adapted to contact the ends of the guttering lengths for preventing the gutter lengths from being positioned over the opening to the spout.
The invention relates to guttering, particularly to guttering unions made of a synthetic resin.
According to the invention a gutter union is at its two ends of greater internal radius than the intermediate position, so providing at each end a Zone to receive a sealing strip or gasket. As it is preferred that the thickness of the wall of the union should be substantially the same throughout its length, the external radius of the gutter union at both of its ends is correspondingly greater than the external radius of the union wall intermediate the two end zones.
The gutter union may, for example, comprise a bracket by means -of which the union may be secured to a wall or other supporting surface and/or it may comprise an outlet. The union is preferably provided with inwardly directed flanges and/ or lips for retaining the ends of lengths of gutter in the union. Furthermore the union is preferably provided with stops t-o prevent the ends of the gutters, upon thermal expansion or otherwise, from extending beyond a predetermined position into the union.
The union is preferably made of a synthetic resin, particularly a substantially rigid polyvinyl chloride. It will be understood that the term substantially rigid polyvinyl chloride includes a polyvinyl chloride which in the form of a gutter union of a wall thickness of 0.08 to 0.1 inch can be flexed suiliciently to enable a gutter to be engaged under retaining lips provided on the union.
The invention also provides guttering comprising the union in engagement with at least one length of gutter, and a resilient sealing strip disposed in one of the said end zones of the union and between the union and the gutter. The resilient sealing strip is preferably a synthetic material, particularly neoprene (polychloroprene).
According to the invention furthermore, there is provided a length of guttering comprising the union, a length of guttering extending from each end of the union, a resilient strip in each end zone of the union, and a sealing or barrier member disposed at an intermediate position of the union and in sealing contact with the inner surface of the two lengths of guttering, the sealing or barrier member being in engagement with the union to prevent longitudinal movement of the barrier member relative to the union.
vflange 5 The invention is diagrammatically illustrated by way of example in the accompanying drawings in which:
FIGURE l is a perspective View of one construction of gutter union according to the invention;
FIGURE 2 is a longitudinal section of the construction shown in FIGURE l;
FIGURE 3 is an end view of the construction shown in FIGURE l;
FIGURE 4 is a perspective View of another construction of union provided according to the invention;
FIGURE 5 is a longitudinal section of the construction shown in FIGURE 4;
FIGURE 6 is an end view of the construction shown in FIGURE 4;
FIGURE 7 is a longitudinal section of the union shown in FIGURES 4, 5 and 6 with two lengths of guttering and an intermediate sealing member in position; and
FIGURE 8 is an end View of FIGURE 7.
FIGURES l, 2 and 3 show a gutter union 1 of substantially rigid polyvinyl chloride which is arcuate in transverse section and provided at a mid-position with a downwardly directed outlet 2. At its two ends, both the internal and external radius of the union are greater than the internal and external radius of the adjacent portions of the union, thereby providing at the two ends zones 3 each adapted to receive a sealing strip or gasket, for eX- ample, a strip of synthetic rubber such as neoprene. When the end of a gutter is disposed in the union the external surface of the gutter rests in sealing engagement with the sealing strip disposed in the corresponding zone 3. A sealing strip 3a is shown in position in one of the two zones 3 in FIGURE l.
The union is provided with an inwardly directed flange 4 at each end on one side and with an inwardly directed at each end on the other side, each llange 5 having at its free end a downwardly directed lip 6. Stops 7 are provided on the inner surface ofthe union adjacent to the inner ends of the flanges 4 and 5. The stops 7 limit the distance to which the adjacent ends of two lengths of guttering, for example rigid polyvinyl chloride can extend into the union. The ylimit set by the stops is such that the inner end of each length of guttering does not project over the mouth ofthe outlet 2. The ends of the two gutters are retained in the union and in sealing engagement with sealing strips disposed in the zones 3 by the flanges 4 and 5.
The gutter union 10 shown in FIGURES 4 to 8 is of rigid polyvinyl chloride and comprises a bracket 11 which includes a wall plate 12 provided with apertures 13 by means of which the union may be secured to a supporting surface such as a wall. The bracket 10 is integral with a web 14 which in turn is integral with the seating portion 15 of the union, the seating portion 15 being substantially semi-cylindrical in cross-section. The internal and external radii at the ends of the seating portion 15 are greater than the corresponding radii of the intermediate part 18 of the seating portion, so providing at. each of the two ends a recessed zone 16 for the reception. of a resilient sealing strip 17 of, for example, neoprene. The wall of the seating portion 15 is substantially of the same thickness throughout its length.
The edge of the portion 15 remote from the wall plate 12 is provided with an inwardly directed flange 19 having a depending lip 20. The other edge of the portion 15 has an inwardly directed llange 21 extending along the whole of its length, the ange 21 having a depending lip 22.
In FIGURES 7 and 8 the union 10 is shown joining two gutters 30 of rigid polyvinyl chloride. The ends ofthe two gutters 30 extend into the union with their outer surface in sealing contact with the sealing strip 17 disposed in the recessed, end zone 16 of the union. The longitudinal edges of the gutters 30 are disposed under and in contact with the ilanges 19 and 21 ofthe union.
An arcuate intermediate, sealing member 31 of a exible synthetic resin, for example, polyethylene, is disposed centrally within the union with its outer surface in sealing contact with inner surfaces of the two gutters 3), the member 31 being held in such contact with the gutters 30 by virtue of its resilience and the fact that one of its longitudinal edges is held between the lip 24B and the gutters 30 whilst its other longitudinal edges bears against the flange 20 and is disposed behind the lip 22. Longitudinal movement of the sealing member 31 relative to the union is prevented by the engagement of a transverse rib Z3 on the union in a mating groove 32 on the outer surface of the member 31. It will be understood that such relative longitudinal movement may be prevented in any other suitable manner, for example, the engagement of one or more ribs on the member 31 in a corresponding number of grooves in the union.
The length of the sealing member 31 is such as to accommodate linear contraction of the gutters 3) so that it always overlaps the ends of the two gutters. The member 31 prevents extraneous particles, for example of sand or grit, from reaching the adjacent ends of the two gutters. Such particles could, upon thermal expansion and contraction of the gutters 3G, penetrate between the gutters 3) and the union and so provide a passage through which rainwater could leak.
1. A guttering assembly comprising:
a one-piece gutter union having a channel-shaped seating portion, said seating portion having an intermediate portion and opposite end portions, the end p0rtions having internal walls which are offset outwardly from the internal Wall of said intermediate portion to form sockets at the ends of said gutter union, a spout extending downwardly from said intermediate portion, the upper end of said spout defining a spout opening in the wall of said intermediate portion, said end portions having inwardly directed langes extending from the upper edges thereof over said sockets, stops xedly connected to and projecting inwardly from the inner surface of said intermediate portion on opposite sides of said spout opening and located between said spout opening and said sockets;
a sealing strip, seated in each socket and having its opposite ends extending underneath said flanges for being held in place thereby;
two lengths of channel-shaped guttering extending into said seating portion at the opposite ends thereof and having their adjacent ends spaced apart, the adjacent ends being adapted to engage said stops to prevent said lengths of guttering from overlying said spout opening, said lengths each overlying and sealingly con tacting one, of saidl sealing strips, and extending therebeyond into sliding contact with the intermediate portion of said seating portion, the upper edges of said lengths of guttering extending substantially to said flanges for being held in place thereby.
2. A guttering assembly according to claim 1, in which the iianges on one of said upper edges have downwardly extending ears thereon defining channels between the ears and the scaling portion into which extend corresponding edges of the lengths of guttering.
