Description

Drain connector for drain connector of sanitary-ceramic installation items _9, in particular toilet bowls.

The innovation relates to a drain connector for drain connection pieces of sanitary-ceramic furnishings _t in particular toilet bowls.

According to an embodiment of the one described in DBGH 1 973 988 This has a drain connector on the connector with the drain of a sanitary * ceramic piece of furniture, for example of a toilet bowl, the end to be connected has a sleeve-like widening with a male thread. Within This widening is seated by a sealing ring which, by means of a flange ring that can be screwed onto the external thread, is tightened of the flange ring is deformed on the external thread in such a way that it is once firmly against the inner surface of the Expansion and on the other hand firmly against the outside of the drain connection so that a firm connection and seal is made.

With this construction, however, it inevitably occurs

a friction between the quiet on the drain socket within the sleeve-like expansion seated sealing ring. : and when screwing on not only on this sealing ring, but also relative to it in a rotary movement moving flange ring, which results in distortion and possibly destruction of the sealing ring.

The innovation aims to remedy this and suggests inserting a sliding ring that can be rotated relative to it in the flange ring, which rests against the sealing ring and presses on it to prevent the flange ring from being tightened, the relative rotational movement only taking place between this sliding ring ^ ₁ and the flange ring · The sealing ring therefore remains unaffected by this relative rotational movement, can no longer be distorted and therefore no longer destroyed.

This protection of the sealing ring from distortion can be used in a further development of the innovation to the effect that that "an now the sleeve-like widening of the Drain connector on the inside wedge-shaped, which leads to As a result, when the flange ring is tightened, the sealing ring of the sliding ring is even stronger between the sleeve-like expansion the drain connector and the drain clip is wedged and fixed.

Q, per sealing ring can consist of a corresponding elastic material, for example rubber or plastic, and be a simple O-ring. It can also be a combination of a Θ-ring and a lip ring, with five central O-shaped bulges being assigned to lips on both sides. The design can be chosen so that the middle bead, similar to the O-ring, when only one is used, engages in an annular groove that may be provided on the drain.

The sliding ring is preferably made of metal, but can also be made of a suitable, suitably strong plastic material

be made. The flange ring used for fastening in a further development of the innovation, it is advisable to have ribs on the outside, which enable better handling of this flange

enable ring.

Finally, in a further development of the innovation, a cuff ring is also provided, which is based on the innovation according to the invention Drain connector is attached and can be moved in its axial direction. He sits down when built Drain connector on the socket pipe sunk in the ground and thus gives an absolutely clean connection.

In Fig. 1, indicated generally at 1, is a drain connector which is inserted into the socket 2 of a drain pipe. The connection between the outlet connector and socket of the discharge pipe is Sm individual is not dargestellx recognizable single lent the sleeve 3 "the ducklings of the flow in the Verbindere

is slidable that it sits on the floor and thus the Neatly covers the connection between drain connector 1 and socket 2.

At the other end, the drain connector 1 is sleeve-like at 4 widened. A thread 5 is provided on the outside.

As can be seen in FIG. 2, a sealing ring is seated in the sleeve-like expansion, which is shown in FIG. 2 as an O-ring 6 and shown at the bottom as lip ring 7 in FIG. 2.

Of course, the two cross-sections of the rings 6 and 7 shown are alternatives; H. one uses either an O-ring 6 or a lip ring 7.

To accommodate the sealing rings 6 and 7, a corresponding groove 9 can be provided in the outlet connection δ, into which the O-ring 6 engages according to FIG. Even with a lip ring? such a groove can be provided as a look mti "Fig. 3 reveals. Then the ring 7 * is designed so that the middle lip is a little longer and stronger so that it can sit in the groove 9 middle part, as can be seen at 7 "in FIG. 4, is pressed somewhat into the cavities which separate the middle lip from the side lips.

A slide ring 1Θ rests against the sealing ring 6 or 7 made of metal or a correspondingly solid plastic »the opposite to the flange or union ring 11 along the surface 12 slide onto the thread of the wider 4 when screwing on

It can also be seen in the example shown that the contact surface 13 of the sliding ring 12 with the sealing ring 6 or 7 is slightly beveled against the plane of the ring, so that a good pressure of the sealing ring 6 or J on the end 8 of the outlet connection is ensured is.

The dashed line is at 14 in Flg. 2 indicated above, since & the inner surface of the sleeve-like expansion 4 can be pure inclined surface, whereby the or 7 press together even more and thus improve the accordingly.
