"Sewer pipe equipped with a rolling ring seal"

The invention relates to a sewer pipe which is equipped with a rolling ring seal and thereby enables a tight connection to the next sewer pipe.

Sewer pipes equipped with rolling ring seals are generally known. Especially with the sewer systems for House drainage etc. are made of stoneware

00981670316

Pipes inserted, one end an insertion end, the other « end have a socket end, the spigot end being inserted into the socket end and a rolling ring between the two is arranged, which unrolls on insertion on the insertion end, so that it is approximately in the middle of the length the socket of the socket end lies on the spigot end. The then still free space of the socket end can be closed with a sealing I) medium.

Difficulties with this type of seal are that that it must be avoided that when the insertion end is pushed into the socket part of the socket end of the pipe Rolling ring located on the spigot end moves on this spigot end, for example due to on the End of existing moisture, from slippery soil or the like.

It is also difficult to ensure that the connection of the pipes with the one used by the client or architect prescribed rolling rings takes place, since it is difficult to control which rolling ring the worker is during of assembly on the spigot end of the pipe.

The invention is based on the object of creating a rolling ring seal that enables these two

Problems that exist with the previously known types of seals, be solved. According to the invention it is proposed to solve a problem provided in the outer wall of the insertion end To insert a recess that is used to hold a part of the rolling ring pulled onto this spigot end. serves. The procedure here is preferably such that the rolling ring hits the plug-in end and thus into the recess the insertion end is already placed in the company producing the sewer pipes, so that unwanted or Deliberate mix-ups of the rolling rings when assembling the sewer system are no longer possible. As a result of that the rolling ring is located in the recess provided on the outside of the spigot end, the rolling ring is forced, roll over the edge of the recess when inserting the insertion end into the socket part of the pipe, so that thereby the rolling movement of the rolling ring is forced on the ring. There is a sliding of the rolling ring on the sleeve therefore no longer possible. In order to force this rolling movement of the ring with even greater security, according to a Another feature of the invention proposed, at least one provided on the outer circumference of the rolling ring approach to be provided which engages in the groove provided at the insertion end.

In order to ensure that the groove provided at the insertion end during the burning process, i.e. during the period

in which the actual sewer pipe is still soft, is not deformed, and to further ensure that In any case, the rolling ring must execute a rolling movement when the insertion end is pushed into the socket part according to a further feature of the invention provided to provide a tooth-like recess at the insertion end and on the roll * ring to arrange a tooth-like approach that cooperates with the tooth-like recess. Of course Several tooth-like recesses and several tooth-like attachments can also be provided. Preferably then continue provided that the tooth-like recess is inclined with its longitudinal axis to the longitudinal axis of the tube, namely so that the slope to the socket end of the same pipe is executed, so that the one fitted into this slope Rolling ring is forced to roll away over the tooth-like projection which is provided towards the socket end, so that thereby the rolling movement of the rolling ring is achieved with certainty.

About the advantages already described, which are achieved by the inventive Formation of the tube and the rolling ring are achieved, that a transport protection is also achieved the pipes is guaranteed, since the pipes no longer have to be stored stoneware on stoneware,

but the tubes lie on the rolling rings pulled onto them on, so that thereby a very inconsequential protection of the Pipes during transport and storage is achieved.

Further advantages and features of the arrangement according to the invention can be found in the following description with reference to the drawing emerged. The drawing shows in

Pig. 1 is a view of two pipes assembled and in

Pig. 2 shows the arrangement of the rolling ring according to the invention on the spigot end of the pipe on a larger scale.

In the drawing, 1 and 2 denote two sewer pipes, for example made of stoneware, as they do usually used for sewerage of house drainage. These pipes each have an insertion end 5 and a socket end 4 on, the insertion end 3 being pushed into the socket end 4 of the pipe to be connected when the pipes are being assembled will. The seal between the sleeve and the plug-in part is carried out by a rolling ring 5, which is pulled onto the front end of the plug-in part and which moves when the The male part rolls into the sleeve on the male part and so comes to lie approximately in the middle of the length of the sleeve for sealing the sleeve and the plug-in part.

The new design of the rolling ring and the plug-in part is clearer from Pig. 2 emerges. It can be seen here that a tooth-like recess 6 is provided in the plug-in part 3, the longitudinal axis of which is oriented obliquely, namely for Socket end of the pipe. The rolling ring 5 to be drawn onto the plug-in part has a tooth 7 which, in adaptation is formed on the tooth-like recess 6 and is inserted into this. It can be seen that when the Insert part with the on it according to Pig. 2 trained and arranged rolling ring 5 the rolling ring is forced, then, when it comes into contact with the inner wall of the socket of the pipe to be connected, roll over the edge 8, so that regardless of whether the spigot is smeared with a slippery, clayey material or not, the rolling ring executes the desired and desired rolling movement when pushed onto each pail

Of course, instead of one tooth and one tooth-like recess, it is possible to use several of these shapes Provide teeth and recesses, other recesses are also possible. The present tooth-like recess however, it has the advantage that, when the tubes are fired, when the tubes are still soft, deformation occurs this type of recess does not occur and that the desired, forced ^ rolling movement of the ring with certainty

is achieved. The invention is therefore in no way the illustrated embodiment is limited.
