Description
AUSTRALIA Patents Act 1990 COMPLETE SPECIFICATION Standard Patent Applicant(s): Darren William Lenthall Invention Title: Pipe Cap The following statement is a full description of this invention, including the best method for performing it known to me/us: - 1 PIPE CAP Technical Field 5 The present invention relates to a pipe cap, in particular to a pipe cap for use with riser pipes or conduits for plumbing, electrical or telecommunication conduits. Background Art 10 An integral component of the construction of a building is the laying of pipeworks for plumbing, electrical and telecommunications installations. Typically, various pipes and conduits are configured to extend through the 15 formwork of a foundation or floor (and later through a poured concrete slab), with substantially vertical riser pipes being used to later connect sub-floor pipeworks with plumbing, electrical and telecommunications installations in the construction and fit-out process. 20 It is common for the aforesaid riser pipes to extend above the formwork or cured concrete slab for up to 1000 mm, although an effective height in a range of about 50 mm to 300 mm is more typical. Additionally, as a result of 25 intentional and unintentional breakage, the riser pipes may have a jagged end. It is clear that the upright riser pipes present a trip hazard and tradespeople working in the vicinity frequently incur foot, shin and ankle injuries as a result thereof. The riser pipes also 30 provide an obstacle for vehicle traffic on the work site, where convenient delivery of building materials could otherwise be made. 7369637 1 (GHMatters) P76179.AU.1 JMFAD 1/02/16 - 2 The open riser pipes on site are a ready waste disposal site for debris and excess slurries produced by tradespeople such as tilers and bricklayers. When concrete is poured onto the formwork there is also the 5 possibility of wet concrete entering the riser pipes, curing in the pipework, and causing downstream blockages. The riser pipes for plumbing installations are connected to sewer pipes, and to minimize sewer smells emanating 10 into the workspace, it is known to block the ends of the riser pipes with cloth rags and paper. The present invention seeks to overcome at least some of the above mentioned disadvantages. 15 Summary of the Invention In its broadest aspect, the invention provides a pipe cap for use with a riser pipe. 20 Accordingly, in a first aspect of the invention there is provided a pipe cap for sealing a hollow elongate member, the pipe cap comprising: a cover for location at an end of the hollow elongate 25 member; and, an engagement member extending from the cover and configured to engage the hollow elongate member in a manner to locate the cover at the end thereof, wherein the cover is provided with a sacrificial opening. 30 In use, the hollow elongate member is arranged to extend substantially vertically through formwork of a building foundation or floor. In general an end thereof is 7369637 1 (GHMatters) P76179.AU.1 JMFAD 1/02/16 - 3 configured to be substantially flushly aligned with an upper surface of the building foundation or floor. However, it will be appreciated that the end of the hollow elongate member may alternatively be spaced apart from 5 upper surface. According to the invention, the cover is provided with a sacrificial opening. In circumstances where pooling of water occurs on the upper surface of the building 10 foundation or floor, the sacrificial opening in the cover of the pipe cap may be broken to allow drainage of excess water through the hollow elongate member. In one embodiment of the invention, the engagement member 15 has an exterior dimension corresponding to an interior dimension of the hollow upright elongate member such that the engagement member can be inserted into the hollow upright elongate member to locate the cover at the end thereof. 20 In an alternative embodiment of the invention, the engagement member has an interior dimension corresponding to an exterior dimension of the hollow upright elongate member such that the engagement member can be positioned 25 over the hollow upright elongate member to locate the cover at the end thereof. In one embodiment, the engagement member may be a closed hollow section. In an alternative embodiment, the 30 engagement member may be an open hollow section. In one form of the invention, the engagement member may be snugly, abuttingly or threadingly engaged with the hollow 7369637 1 (GHMatters) P76179.AU.1 JMFAD 1/02/16 -4 elongate member. In a further embodiment, the engagement member is mounted to extend substantially perpendicularly from the cover. 5 In another embodiment, a periphery of the cover corresponds to an exterior dimension of the hollow elongate member. In a preferred embodiment, the periphery of the cover extends beyond the exterior dimension of the 10 hollow elongate member. In a further embodiment of the invention, an upper surface of the cover is convex. The upper surface may be provided with a plurality of indentations and/or protrusions 15 configured to provide a non-slip surface. Brief Description of the Drawings The preferred embodiments of the present invention will 20 now the described, by way of example only, with reference to the accompanying drawings, in which: Figure 1 shows a side view of a pipe cap according to one embodiment of the present invention; and, Figure 2 shows a plan view of the pipe cap of Figure 1. 25 Detailed Description of Specific Embodiments Referring to the Figures, where like numerals refer to like features throughout, a pipe cap 10 for sealing a 30 hollow elongate member 100 is shown. In one embodiment the hollow elongate member 100 may be a plumbing pipe, even more particularly a riser pipe arranged, in use, to extend substantially vertically through formwork or a 7369637 1 (GHMatters) P76179.AU.1 JMFAD 1/02/16 - 5 concrete slab of a building foundation or floor such that an end 110 thereof is configured to be substantially flushly aligned with an upper surface of the building foundation or floor. 5 The pipe cap 10 includes a cover 12 for location at the end 110 of the hollow elongate member 100 and an engagement member 14 extending from the cover 12. The engagement member 14 is configured to engage the hollow 10 elongate member 100. In a preferred embodiment of the invention, the engagement member 14 has an exterior dimension 16 such that the engagement member 14 can be inserted into the hollow elongate member 100 to locate the cover 12 at the end 110 thereof. Preferably, a lower 15 surface 11 of cover 12 abuts the end 110 of the hollow elongate member 100. In this way, the cover 12 is also substantially flushly aligned with an upper surface 120 of a building foundation or floor and does not present a trip hazard. 20 Typically, the engagement member 14 is slidingly located within the hollow elongate member 100. In alternative embodiments of the invention, however, the engagement member 14 may be threadingly engaged within the hollow 25 elongate member 100, the exterior dimension 16 of the engagement member 14 and an interior dimension 102 of the hollow elongate member 100 being provided with respective corresponding threads. 30 The hollow elongate member 100 is of conventional design suitable for the specific purpose for which it is employed in a building construction. Accordingly, it will be appreciated that an exterior dimension 104 and the 7369637 1 (GHMatters) P76179.AU.1 JMFAD 1/02/16 - 6 interior dimension 102 of the hollow elongate member 100 may vary according to the type of the hollow elongate member 100 employed and its purpose. For example, riser pipes for plumbing installations may have an interior 5 dimension 102 of 100 mm and an exterior dimension 104 of 110 mm. The exterior dimension 16 of the engagement member 14 corresponds to the interior dimension 102 of the hollow 10 elongate member 100 such that the engagement member 14 is snugly or abuttingly received therein. Thus, it will be appreciated that the exterior dimension 16 of the engagement member 14 will be selected depending on the size and shape variation of the interior dimension 102 of 15 the corresponding hollow elongate member 100. While the engagement member 14 may be a closed hollow section, preferably the engagement member 14 is an open hollow section for reasons that will be described later. 20 The engagement member 14 is typically mounted to extend substantially perpendicularly from the lower surface 11 of the cover 12. In other applications, however, where the hollow elongate member 100 extends through the formwork 25 with respect to the upper surface thereof at angles other than 90 degrees, for example, at 45 degrees, the engagement member 14 can be mounted to extend at a corresponding angle from the cover 12. 30 In one embodiment of the invention, a periphery 18 of the cover 12 corresponds to the exterior dimension 104 of the hollow elongate member 100. In a preferred embodiment, the periphery 18 of the cover 12 extends beyond the 7369637 1 (GHMatters) P76179.AU.1 JMFAD 1/02/16 - 7 exterior dimension 104 of the hollow elongate member 100. In this way, when, for example, plumbing fixture connections with the riser pipes are installed the pipe cap 10 may be readily prised from, and thereby disengaged 5 from, the hollow elongate member 100. Another additional advantage of the preferred embodiment is that the cover 12 would resist being pushed through the formwork or concrete slab when under traffic. 10 Preferably, an upper surface 13 of the cover 12 is slightly convex to provide additional strength and resilience to traffic. The upper surface 13 may also be provided with a plurality of indentations and/or protrusions configured to provide a non-slip surface. 15 In one embodiment of the invention, the cover 12 is provided with a sacrificial opening 20. In circumstances where pooling of water occurs on the upper surface of the building foundation or floor, the sacrificial opening 20 20 in the cover 12 of the pipe cap 10 may be broken to allow drainage of excess water through the hollow elongate member 100. The sacrificial opening 20 can be forced open by manually applying pressure thereto. 25 The sacrificial opening 20 comprises one or more perforations, grooves, or indentations configured to facilitate one or more apertures to be formed in, and extend through, the cover 12 when said perforations, grooves, or indentations are subjected to manually applied 30 pressure. Application of manual pressure will be understood to also include the engagement of tools such as, for example, an awl or screwdriver head with the cover 12 to allow one or more apertures to be formed in, and 7369637 1 (GHMatters) P76179.AU.1 JMFAD 1/02/16 - 8 extend through, the cover 12. It will be appreciated that in an alternative embodiment of the invention, the engagement member 14 has an interior 5 dimension corresponding to an exterior dimension 104 of the hollow upright elongate member 100 such that the engagement member 14 can be positioned over the hollow upright elongate member 100 to locate the cover 12 at an end 110 thereof. 10 The materials of construction of the pipe cap 10 described can be any suitable materials typically used for plumbing fixtures, and that can be shaped, formed and fitted in the manner so described, and include a plastics material such 15 polyvinyl chloride (PVC), chlorinated PVCs, high density polypropylene (HDPE), cross-linked polyethylenes such as PEX-a and PEX-b, plastics based on acrylonitrile butadiene-styrene copolymers (ABS), and so on. 20 In use, the advantages of employing the pipe cap 10 of the present invention to seal hollow elongate members 100, in particular riser pipes, include: (1) minimises sewer smells emanating from riser pipes connected to sewer pipes; 25 (2) prevents debris, slurry, and wet concrete from a concrete slab pour from entering pipeworks; (3) enables all pipes extending through formwork to be cut off after a concrete slab pour and capped in order to provide a flat surface with minimal 30 trip hazards for tradespeople to work upon and/or vehicle deliveries to be made directly onto the concrete slab; (4) minimizes foot, ankle, and shin injuries; 7369637 1 (GHMatters) P76179.AU.1 JMFAD 1/02/16 - 9 (5) provides a temporary seal for drainage installation and pre-lay, which can then be re used when concrete slab pour occurs; (6) sacrificial opening in pipe cap 10 allows 5 drainage of excess water pooling on upper surface of foundation or floor; and, (7) can be readily fitted and removed by tradespeople, apprentices, and trades assistants. 10 In the description of the invention, except where the context requires otherwise due to express language or necessary implication, the words "comprise" or variations such as "comprises" or "comprising" are used in an 15 inclusive sense, i.e. to specify the presence of the stated features, but not to preclude the presence or addition of further features in various embodiments of the invention. 20 It is to be understood that, although prior art use and publications may be referred to herein, such reference does not constitute an admission that any of these form a part of the common general knowledge in the art, in Australia or any other country. 25 Numerous variations and modifications will suggest themselves to persons skilled in the relevant art, in addition to those already described, without departing from the basic inventive concepts. All such variations 30 and modifications are to be considered within the scope of the present invention, the nature of which is to be determined from the foregoing description. 7369637 1 (GHMatters) P76179.AU.1 JMFAD 1/02/16 - 10 For example, the cover 12 may have different shapes, such as a polygonal or square shape. The pipe cap 10 or, indeed, solely the cover 12, may be provided in a variety of coded colours to allow for ready visual recognition. 5 It will also be appreciated that while the above description applies in the main to the use of the pipe cap 10 to seal plumbing pipes, in particular riser pipes, the pipe cap 10 of the present invention may also be suitably 10 employed to seal alternative hollow elongate members 100 used in the construction industry, such as, for example, conduits for electrical and telecommunication cables. 7369637 1 (GHMatters) P76179.AU.1 JMFAD 1/02/16
