Definitions

• This invention relates to a floor connection for sewers for connecting different discharge units, for example water closet, wach-basin, draining gutter 3 etc.
• the invention particularly relates to a sewer connection in such cases when rooms are concerned in which plastic floors are laid, as is generally the case in toilets, washrooms and the like.
• the present invention has the object to eliminate the aforesaid drawbacks and to provide a sy-stem for con-** necting discharge units to sewers, which system comprises a smaller number of components than the technique and which, besides, yields good sealing against the floor covering and eliminates dust- and moisture-collecting crevices and which, above all, prevents the propagation of moisture.
• This object is achieved according to the present invention, in that the sewer connection unit con ⁇ sists of a lower or outer member, which at the lower end can be connected to a standard sewer while an upper or inner member is adapted for insertion into the lower mem ⁇ ber.
• the inner member is adapted at its lower end to con ⁇ stitute a connection for the discharge unit in question, which connection alternatively can be effected by means 5 of an insert for the inner member when a reduction in di ⁇ mension is required.
• the floor covering is clamped at its mounting either between the outer member and the inner member or between the latter member and an insert there ⁇ for. * Sealing is brought about by an 0-ring, which at the
• the different members comprised can be arranged so as to substantially form at their mounting a common
• 25 covering generally is heated at its mounting in order to cause it to shrink and upon its cooling, gives rise to a leakage gap, when no O-ring is provided.
• connection unit proper When a connection is to be exchanged against another one, a suitable tool is inserted and the inner member or mem ⁇ bers are broken away without causing damage on the fixed outer err lower member, whereafter a suitable inner connect-
• 35 ing member can be inserted.
• Fig. 1 shows two arches including one sewer sys ⁇ tem according to the present invention and, respectively, one sewer system according to conventional technique
• Fig. 2 is a cross-section showing in greater detail how a connection according to the invention looks when a maximum connection dimension is utilized
• Fig. 3 shows the utilization of the invention when a discharge unit with a smaller outgoing dimension, for example a wash- -basin, is connected
• Fig. 4 shows a suitable water seal design.
• Fig. 1 two arches, an upper one and a lower one are shown, into the upper one of which a sewer system of such a kind has been cast that it can be built up on the basis of the invention subject matter, and of which all connections at this stage have an identical appearance.
• a system of conventional type is shown which, as can be seen, results in a much greater number of different members and in greater diffi ⁇ culty of making sealings and connections to the floor cover- ing.
• the water seal function correspond ⁇ ing to the water seal shown in the lower arch, for example the one shown in Fig. 4 can be used.
• connection' according to the invention comprises a lower member 1 , which is cast-in in the arch and in its. turn connected to the sewer system.
• the upper surface of the lower mem ⁇ ber 1 is cast-in aligned with the cast floor.
• an inward facing recess extending all about is made for receiving a clamp ⁇ ing ring 2.
• Said ring is provided at its lower end with a hook-like flange 5 projecting in lateral direction and intended to engage beneath a flange-like radially inward projection- 4 on the lower member 1.
• a connecting piece 3 from the water-closet can be inserted into the clamping ring 2, into which an 0-ring 16 has been laid in an internal groove therein.
• the clamping ring 2 can be formed in the way as indicated by dash-dotted line in Fig. 2.
• Fig. 3 is shown how th-e connection according to the invention has been provided with an intermediate piece 8, which is held in place in the floor member 1 by means of an O-ring 16, which snappingly engages with grooves facing toward each other in the intermediate piece 8 and, respectively, the floor member 1.
• a recess for a sewer connection is provided which is identical with the one shown in Fig. 2, except for the diameter which for this connection is smaller.
• the clamp- ing ring here is designated by 9, the locking flanges are designated by 14 and 15, and the sealing 0-ring is designated by 17.
• a connecting conduit 0, for example to a wash-basin can then be con ⁇ nected by using an O-ring 11 in conventional manner.
• the clamping ring 2 clamps the floor covering 7, but in this case against the recess wall of the intermediate piece 8.
• Fig. 4 shows how a water seal suitably can be design- ed so as together with the afore-described details form a sink in the floor.
• the water seal includes a clamping ring 21 , which internally transforms to a downward directed funnel 22, on which a lower water seal portion 24 is attach ⁇ ed via radial flanges 23 by means of threads.
• the floor covering 7 has been clamped in the same manner as in the above examples.
• the floor memb.er 1 further is connected to a bend 5 of conventional kind with a sealing by means of an 0-ring 26, which connection was made prior to the casting-in operation.
