- the connecting branch portion advantageously comprises, as seen in cross section, curved connecting branch portion side walls 15a and 15b adjoining the cylindrically shaped connecting branch end wall portions 16a and 16b.
- a connecting branch portion 4 results in an easy instalment of a discharge portion 2 comprising, as seen in cross-section, the same curved side walls 13a and 13b adjoining the cylindrically curved end wall portions 14a and 14b of the discharge portion.
Abstract
Description
- The invention relates to a plastic gully provided with an integral connecting branch portion in which a discharge portion is fixed.
- A plastic gully of this type is known in the art. The wall of this known plastic gully is provided with an opening which has been obtained by deformation of the wall of the plastic gully in which a discharge portion is fixed.
- Narrow tolerances should be maintained to obtain an optimum adhesive connection whereas an instalment of the said discharge portion is very time-consuming.
- The use of an adhesive is the more cumbersome because the evil smell and evaporation of harmful volatile agents in the adhesive.
- The quality of an adhesive connection in addition being extremely dependent upon the person, who applies the same, great differences in quality of said adhesive connection may occur and it therefore frequently happens that the adhesive connections of discharge portions adhered to plastic gullies will get lost during their conveyance.
- As plastic gullies of this type accommodated beneath traffic roads are subjected to various different loads, the rigid adhesive connection will be easily damaged after instalment of the gullies in a conduit system.
- The present invention aims to provide a plastic gully of the aforementioned typeallowing an extremely rapid fixing of the discharge portion without the use of any adhesive.
- This object is achieved in accordance with the invention in that the discharge portion snappingly engages the connecting branch portion.
- Obviously a discharge portion may thus be received in a connecting branch portion in an extremely rapid and convenient manner, thereby forming an optimum connection between the said connecting branch portion and the plastic gully.
- Very advantageously the discharge portion is held in a snapping engagement with the connecting branch portion by pressing the discharge portion adequately from inside the plastic gully through the opening bounded by the connecting branch portion.
- This provides the advantage that an extremely good engagement may be rapidly obtained.
- Very conveniently a sealing ring is provided between the discharge portion and the connecting branch portion, said sealing ring being advantageously accommodated in the snap connection. In this manner a very flexible connection between the discharge portion and the plastic gully is obtained so that damages and leakages of the connection during conveyance of the plastic gullies are, after mounting the discharge portion, almost excluded, whilst moreover, no narrow tolerances need to be maintained.
- Very advantageously the connecting branch portion comprises cross-sectionally curved connecting branch portion side walls, adjoining the curved connecting branch portion and wall parts, so that a discharge portion can be used comprising spherical side walls, which discharge portions provide a great lateral stability to the discharge portion. More particularly leakage at the sides of the discharge portion is avoided in this manner.
- It is to be recommended in particular that the discharge portion is connected with a removable stench screen to easier clean plastic gullies which are being used as inspection gullies or as sewage gullies.
- To obtain a removable stench screen said stench screen is clampingly retained which preferably is attained by means of two ribs provided on the inner wall of the discharge portion clampingly engaging the stench screen between the top of the connecting branch portion.
- The invention will be illustrated with respect to an embodiment in the drawings, wherein
- Fig. 1 is a lateral section of a plastic gully according to the invention;
- Fig. 2 is a section according to line II-II;
- Fig. 3 is a side view of a plastic gully according to the invention and
- Fig. 4 illustrates a view according to line IV-IV.
- Fig. 1 illustrates a
plastic gully 1 conveniently consisting of polyvinylchloride. Theplastic gully 1 comprises a shaft connected to abottom 9. - The used plastic gully consists in many cases of two components, the component as illustrated in the figures functioning as lower part of the plastic gully upon which lower part the upper component is mounted.
- A pipe part or shaft la is provided with a connecting
branch portion 4 by heating the area to be widened in the wall of the gully, by means of electric elements and by subsequently providing a widened portion by means of an inner and outer mould, said portion forming a connectingbranch portion 4 after removal of the wall. - The connecting
branch portion 4 is provided with an inwardly directed wall portion forming an inwardly directededge 10. - The plastic gully according to the invention also comprises a
plastic discharge portion 2, provided with a ledge-shaped elevation 11 and a secondannular edge 12 located at distance from the ledgeshaped elevation 11. - On outwardly pressing
discharge portion 2 through opening 8 from the inner side of the plastic shaft la, the inwardly directededge 10 will be slightly deformed and will subsequently be set behind the ledge-shaped elevation 11. - In this manner an optimum snapping engagement 3 is obtained.
- A
sealing ring 5 provided in the space between ledge-shaped elevation 11 andannular edge 12 simultaneously ensures an optimum seal, since said sealing ring seals the inner side ofshaft 1 and the outer side ofdischarge portion 2. - A plastic gully in accordance with the invention has to be provided with a
stench screen 6 being clampingly retained between the upper wall ofdischarge portion 2 andledges 7, provided on the inner side ofdischarge portion 2. - An easy removal of
stench screen 6 enables an appropriate cleaning of the plastic gully, thus creating a good open connection betweendischarge portion 2 and gully shaft portion la. - The connecting branch portion advantageously comprises, as seen in cross section, curved connecting branch
portion side walls 15a and 15b adjoining the cylindrically shaped connecting branchend wall portions 16a and 16b. - The use of such a connecting
branch portion 4 results in an easy instalment of adischarge portion 2 comprising, as seen in cross-section, the samecurved side walls 13a and 13b adjoining the cylindrically curvedend wall portions - In the above manner an optimum seal and flexible connection are obtained as well as a very high natural stability of the discharge portion respectively, in comparison with a discharge portion comprising flat side walls.
- It is observed that the reference numerals in the claims are not intended to restrict the scope thereof, but are only denoted for clarification.
