The innovation concerns an elastic rolling ring to connect socket pipes.

The 'use of rolling rings in socket pipe connections is known. To connect these pipes tightly, it is necessary to insert the rolling ring deep into the annular gap of the socket. For this purpose, it is known to lengthen the Binsteok tube end by inserting a support body for the rolling ring, which is pulled out through the inside of the insert tube after the rolling ring has been stepped onto the insert tube end. The handling of the carrier body proves to be cumbersome and by stepping over the rolling ring prematurely on the Sinsteckrohr only an insufficiently far introduction of the rolling ring into the socket can be achieved.

It is the job of hiring duroii appropriate Training of the rolling ring to achieve a deep introduction of the same into the socket connection in that the Rolling ring body has a substantially circular cross-section and one as a support body on the peripheral surface serving bendable lip carries. The lip can be designed to be essentially cylindrical and extend either in the area of the central plane of the rolling ring body or on the one facing the rolling ring axis Grip the side at a distance from the center plane on the rolling ring body.

As a result, the lip with the rolling ring body forms a receiving fold for the plug-in pipe end through which the rolling ring is held centered supported in front of the insert tube. The rolling ring held in this way rolls during the insertion process over the edge to the end of the plug-in pipe and ensures that it is deeply immersed in the annular gap of the socket connection. The lip leads through additional deformation of the rolling ring body and support on the sealing surfaces of the socket and Einsteckrohrende a locking of the rolling ring, the lip as an expansion body for the definition of the Rolling ring is used.

In the formation of the fire, the lip can be pushed on be designed with a width that corresponds to about a quarter of the length of the circumference of the rolling ring body. Ss is there

possible, the lip in the plugging direction through, parallel and / or to delimit surfaces extending obliquely to one another, wherein the surfaces are or are straight-lined May have settlements. The rolling ring body and the lip are expedient as a one-piece Yoll body from one elastic material, for example rubber or plastic, or made of a foamed material. Ss corresponds to the principle that the lip can also be designed in another way, for example frustoconical or that, for example, two lips attack the ring body.

The combustion is by way of example embodiments explained in more detail in the drawing. Ss show

3fig. 4 a further rolling ring in section.

A socket 2 is formed on the socket pipe 1 in a known manner, into which the plug-in pipe end 3 of the socket pipe 4 is pluggable with game. The sealing of the socket joint in the area of the annular gap 5 should be through a

Rolling ring 6 made of elastic material. According to the innovation, the rolling ring has a circular rolling ring body 6 'and one acting on the circumferential surface of the same cylindrical Jiippe 7, which in the embodiment is designed to the free volume with decreasing thickness. The inside of the lip 7 and the rolling ring body 6 'form a PaIz, which the Binsteckrohrende 3 of the socket pipe Gate takes on with pretension. As a result, the rolling ring β is fixed centered in front of the plug-in pipe end. When inserting the plug-in pipe end 3 into the socket 4 the rolling ring 6 rolls over the edge 8 of the plug-in pipe end into the annular gap 5 and takes the one shown in FIG Sealing position. Here, the lip 7 lies on the circumferential surface of the rolling ring body 6 'and, like the Figure 2 further shows an additional deformation of the Rolling ring body, which results in a particularly tight closure of the socket connection. The lip 7 lies while on the sealing surfaces of the sleeve and / or the plug-in pipe end and is based on this in addition as Spreader to lock the rolling ring in the socket connection away. In the embodiment of the figures

RoIl-1 and 2 grips the lip at a distance from the 'ring center plane Direction of the rolling ring axis on the rolling ring body. The lip can also deviate in the area of the central plane (Figure 3) be provided. In this embodiment, too, the rolling ring is held at the end of the Sinsteckrohrende and unrolled the same over the edge 8 of the plug-in pipe end

guaranteed.

Finally, the rolling ring body 6 'can also have two Lips 7 may be provided which, for example, engage diametrically (Figure 4) or offset on the rolling ring body.

The rolling ring body 6 'and the lip 7 are similarly made of an elastic one by a one-piece Yollkörper Material or a foamed material can be molded.
