Description

The present invention relates to a device for connecting a discharge pipe of a toilet bowl to a soil pipe.

Conventionally, the discharge pipe of a toilet bowl 5 is connected to the soil pipe by means of some form Of sleeve and is secured in position by various sealing compounds. The use of such a sleeve is first rather inefficient and secondly can take some considerable time to secure in position. There is also the need for such a sleeve which eliminates the necessity of having a socket on the end of the soil pipe.

The present invention is directed towards providing an efficient construction of such a device for connecting a discharge pipe of a toilet bowl to a soil pipe.

According to the invention, there is provided a device for connecting a discharge-pipe of a toilet bowl to a soil pipe, comprising a cylindrical body member having a larger diameter portion, adapted for reception of the discharge pipe,' and a smaller diameter portion, adapted for insertion into the soil pipe, the part of the body member intermediate the larger and smaller diameter portions forming an abutment member, in use, for the discharge and soil pipes, there being provided adjacent the entrance to the larger diameter portion, an interior peripheral seal of elastomeric material for engagement with the discharge pipe, said seal comprising a main tubular body, an external circumferential hook portion on one end of the tubular body, the free leg of the hook portion extending back over the body and co-axial therewith for engagement with the larger diameter portion of the device, and annular projections on each of the interior and exterior of the tubular body.

The invention will now be described by way of example, with reference to the accompanying drawings, in which:Fig. 1 is a perspective view of a device constructed according to the invention, the device being shown in its fully assembled position.

Fig. 2 is a perspective view of a cylindrical body member forming portion of the device, Fig. 3 is a perspective view of a seal forming portion of the device, Fig. 4 is an underneath plan view of the seal, Fig. 5 is a side view of the seal, and Fig. 6 is a plan view of the seal.

Referring to the drawings there is provided a device, -443397 indicated generally by the reference numeral 1 for .-. connecting the discharge pipe of a toilet bowl to a soil pipe. The device 1 includes a cylindrical body member 2, and an interior peripheral seal 3.

Referring in particular to Fig. 2, the cylindrical body member has a larger diameter portion 4 and a smaller diameter portion 5. The part of the body member intermediate the larger diameter portion 4 and the smaller diameter portion 5 is in; the shape of a ring forming an abutment member 6 substantially at right angles to the portions 4 and 5.

The larger diameter portion 4 has an entrance indicated generally by the reference numeral 7. The smaller diameter portion 5 is provided with three Outwardly directed circumferential flanges 8 which together form two recesses 9 for reception of conventional sealing rings such as rings.

The seal 3 shown best in. Figs. 3 to 6, comprises.a main tubular body 10 and a hook portion Π having a top 12 and a free leg 13 extending back over the main tubular body . The leg 13 terminates in a beading 14. The interior surface of Ihe.leg 13 is provided with a plurality of inwardly projecting annular ribs (not shown). The main tubular body TO tapers from its mouth at 15 towards its lower end at 16 and it wi11 be noted that the external diameter of portion of the main tubular body 10 is reduced discreetly thus 4259? forming annular projections 17 some of which are hidden from view by the leg 13.

Annular projections are formed on the interior of the main tubular body 10 and include an upper annular rib 18, coplanar with and forming an extension of the top 12 of the hook portion 11, and an intermediate annular rib 19 mounted on the interior of the main tubular bodylO and projecting slightly downwards into the main tubular body 10 at a slight angle to the horizontal as shown in the Figs., preferably of the order of 10°. The intermediate annular rib 19 terminates in a beading 20 (see Figs. 4 and 6). A lower annular rib 21 also projecting slightly downwards is provided.

The cylindrical member 2 is manufactured from any suitable plastics material for example polyethylene (P.E.). The seal 3 is manufactured from an elastomeric material such as rubber or styrene butadiene rubber (S.B.R.).

During assembly, in use, the requisite number of sealing rings are placed in the recesses 9 and the interior peripheral seal 3 is placed on the entrance 7 of the larger diameter portion 4. The hook portion 11 grips the larger diameter portion 4, the tightness of the grip being facilitated by the internal annular projections on the hook portion 11 (not shown) and the annular 4250” -6projections 17, only some of which are shown.

The smaller diameter portio'n 5 is then inserted into the mouth of a soil pipe. The top of the soil pipe :5 bears against the abutment member 6, the sealing rings in the recesses 9 providing an adequate seal between the interior of the soil pipe and the exterior of the smaller diameter portion 5. Adischarge pipe of a toilet bowl is then inserted into the larger diameter portion 4.

The discharge pipe bears against the abutment member 6, and the upper annular rib 18, the intermediate annular rib 19 and the lower annular rib 21 are each deformed downwards and outwards towards the interior wall of the larger diameter portion 5.

IS Needless to.say the order of assembly may be reversed, the device being placed on the discharge pipe of the toilet bowl and then onto the soil pipe. Preferably a suitable lubricant is used.

It has been found that with the device according to the present invention it is possible to connect the discharge pipe of a toilet bowl to a soil pipe without the need to use any sealing compounds. If the toilet bowl has to be removed for any reason it is readily removed without necessitating damage to the soil pipe or indeed damage to the toilet bowl.
