FOR PLASTIC PIPE

The innovation relates to a guide cable for plastic tubes, which consists of a metal tube bent and slotted at a given radius.

S The guide part cU-snt for deflection, i.e. the direction

Change in the performance of a plastic pipe, for example for heating* hot and cold water installation or the like.

To change the direction of plastic pipes,

Metal!formed!Ie with specified bending radii are known, such molded parts are used, for example, between the radiator connection and the supply or disposal line in order to accommodate a plastic pipe.

The plastic pipe to be inserted into such a mold must in any case be bent beyond the specified bending radius so that it can be inserted into the undercut of the molded part.

The plastic pipe is cut off if the

This is where the innovation aims to remedy the situation.

The innovation, as characterized in the claims, solves the problem of having a guide part for the deflection of plastic pipes,

which allows the plastic pipe to be guided through it without having to bend the radii too narrowly when inserting it and prevents damage to the plastic material of the pipe wall.

The advantages achieved with the new molded part I are essentially that it enables the plastic pipe 2 to be easily inserted into the guide part 1 at the construction site

without any tight, critical bending radii of the

plastic pipe 2 can be achieved and any risk of damage to the plastic material in the pipe wall of the plastic pipe 2 is excluded. The guidance of the plastic pipe 2 is guaranteed by the molded part 1 in every radius. The spiral shape makes it easy to screw the plastic pipe into the molded part and give it the required change of direction. The risk of kinking the pipe is definitely avoided.

The innovation is explained in more detail below using an example shown in the figures.

The guide element consists of a one-piece, axially spirally bent molded part 1, which is additionally bent in a predetermined bending radius.

The molded part can be made either from a metal tube that is slotted about halfway, which is twisted spirally around its axis and then bent to the corresponding radius. This results in a shape as can be seen in Figure 1, with the outer casing Ib visible at the left end, while this then merges into the inner wall la in the top view, which in turn, from about the middle, merges again into the outer casing Ic at the opposite end.

In Figure 2, the molded part 1 is shown in side view, whereby the corresponding reference symbols illustrate the type of axial rotation and radial bending of the molded part compared to Figure 1.

The molded part can also be made from a sheet metal strip bent into a tubular shape.
