Description
Fromn: 06/03/2007 15:46 4016 P.004/014 This invention relates primarily to drains and has been devised particularly though not necessarily solely for use as a drain in a gravity fed drainage system.
IND Most drains presently available for use in gravity fed drainage systems, such as shower 0 drains, have male and female members which are engagingly threaded so that* the male member may be screwed into the female member in such a way that peripheral flanges on the 00 female and male member respectively are positioned in use above and below the supporting 0 structure,. for example the shower fray. A seal such as a compressible o-ring is then usually 0 positioned between the underside of the fray and the upper surface in use of the flange on the o female member. This construction causes a space to be created between the flanges on the male member and the female member in to which water can become positioned for example, if the drain is poorly installed or if there is matter, such as a splinter of wood, leading to distortion of the seaL If the o-ring seal inadequately seals between the flange on the female member and the underside of the tray water can leak through the space and in time can cause damage to the supporting floor, If the floor is wooden ultimately parts of the floor may rot away.
This is of course disadvantageous.
It is therefore an object of the present invention to provide a connection and/or a drainage member and/or a drainage construction which will obviate or minimise the foregoing disadvantages in a simple yet effective manner or which will at least provide the public with a usefuil choice.
Accordingly in one aspect the invention consists in a connection comprising a first female member and a second male member, engageable threads on the inner surface of the female member and the outer surface of the male member, at least one slot formed in the threads on the inner surface of the female member or in the threads on the outer surface of the male member, or both, the slot or slots extending substantially longitudinally of the female member and/or the male member, the or each slot having a depth greater than the depth of the threads so that when the male member is engaged in the female member a passageway or passageways past the threads is provided by the slot or slots.
Preferably there are a plurality of slots.

To those skilled in the art to which the invention relates, many changes in construction and widely differing embodiments and applications of the inven tion will suggest themselves without departing from the scope of the invention as defined in the appended claims. The disclosures and the description herein are purely illustrative and are not intended to be in any sense limiting.
One preferred form of the invention will now be described with reference to the accompanying drawings in which, Figure I is a cut-away perspective view of a female member for use in the invention, Figure 2 is a perspective top view of the fiemale member of Figure 1, Figure 3 is a cross-sectional view of a connection or drainage constructions according to one preferred form of the invention, and C:\Documenls and Settnas\kbennett\Local SettnwATemnomdrv Internet Fi~es\OLKICM7O465AU PS 20060302 947 NPB (3)40 COMS ID No: SBMI-06502831 Received by IP Australia: Time 16:43 Date 2007-03-06 Fro m: 06/03/2007 15:48 #016 P.W07/014 -4- Figure 4 is a further part cross-sectional view of the construction of Figure 3I.
Referring to the drawings a connection, a drainage member and/or a drainage construction IND are provided as follows. A female member 1 is provided which is open at end 2 and opposite 0 end 3. In the embodiment shown in Figure 1 the opening at the end 2 is of substantially larger diameter than the opening at end 3 but this will depend upon the purpose and 00 geometry of the construction in which the drainage member is to be used. A cylindrical 0 section 4 is provided into which internal threads 5 are cut.
One or more, and preferably a plurality such as four slots, are provided across the threads o The slot or slots 6 are preferably shaped so that the female member can be formed by the use of a collapsing core mould to facilitate the speed of operation of the mould. Thus for example, the slots 6 may taper from the upper end 7 to the lower end 8 at an angle as can be determined for the particular use to which particularly the female member is to be put. In the embodiment shown in Figures 1 and 2, which are for use as a shower tray drain, the angles may be about 7 degrees. It can also be seen that the side walls for example 9 and 10 of the slot can be shaped, such as curved, so that the back wall of the slot 6 is a little narrower than the open space opposite the back wall of the slot 6.
The slots 6 are provided so that they extend inwardly a greater distance tha the threads.
This can be clearly seen for example in Figure 1. Again the exact distance that the slots extend past the threads will depend on the actual use to which the embodiment is put but in the embodiment shown in Figure 1 the depth is for example, two to three times the depth of the threads. At the bottom of the slot 6 a ledge 12 is provided and in such a construcetion the ledge 12 must be at a position lower than the maximum downward extent of threads 20 on an inner male member 2 1. The male member 21 is also open at the upper end 22 and the lower end 23 thereof Thus for example the lower end 24 of the threads 5 terminates below the lower end 25 of the threads 20. Referring to Figure 4 it can be seen that ledge 12 is therefore below the position of the lower end In alternative constructions the slots 6 could be cut into the male member 21 or indeed slots could be provided in both members.
C:\Documents and Settines\kbsnnett\ocaI SettineAsTemnorarv Internet Eiles\OLICl 70465AU Ps 20060302 947 NPB (3tdoc COMS ID No: 5BMI-06502831 Received by IP Australia: Time 16:43 Date 2007-03-06 From: 06/03/2007 15:48 #016 P.008/014 In other embodiments of the invention again depending on the geometry of the construction ledge 12 may not be provided, for example, where the inlet and outlet opening of the female member are substantially similar in diameter.
In use the female member 2 is brought up under the, for example, shower tray 30 so that an outwardly extending flange or rim 31 for example, having an upstand 32 butts the underside of the tray 30 and the male member is then screwed into the female member so that an outwardly extending rim 35 on the male member abuts the upper surface of the fray 30. An o-ring 36 may provide a seal between the underside of the member 30 and the flange 31.
The provision of the slots 6 mean that any water collecting between the flanges 35 and 31 will drain to the outlet of the female member through the slots 6.
Thus it can be sent that at least in the preferred form of the invention a connection and/or a drainage member or drainage construction are provided which have the advantage that any water collecting in the vicinity of the flanges which clamp above and below the supporting structure such as a shower tray will tend to drain away from that position through the slot or slots 6. It is a particular advantage of the construction of the preferred form of the construction that a collapsing core mould can be used for high speed production of the female member. Furthermore the slots 6 reduce any tendency for capillary action up the threads to occur.
