Abstract

A supply system ( 1 a ) includes a basic body ( 2 ) and at least one supply port ( 3 through 8 ), which is flush-mounted in the basic body ( 2 ) and provides a supply medium. The basic body ( 2 ) extends along a longitudinal axis and includes a plurality of outer wall sections ( 9 through 12 ) and at least one connection section ( 13 through 16 ). The connection section or each connection section ( 13 through 16 ) mechanically connects to one another two outer wall sections ( 9 through 12 ), which are adjacent to one another. At least one connection section ( 13 through 16 ) has at least one undercut ( 17 through 24 ). The undercut or each undercut ( 17 through 24 ) has the form of a channel or flute or groove or sectional rail and extends along the longitudinal axis of the basic body ( 2 ).

First claim

The invention claimed is:

1. An arrangement comprising:
a supply system, the supply system comprising:
a basic body extending along a longitudinal axis, the basic body comprising:
a plurality of outer wall sections; and
a first connection section and a second connection section mechanically connecting two of the outer wall sections to each other, the two connected of the outer wall sections being adjacent to one another, each of one of the first connection section and the second connection section comprising two undercuts, each of the undercuts having a channel form or a flute form or a groove form or a sectional rail form, each of the undercuts extending parallel to the longitudinal axis; and

at least one supply port flush-mounted in the basic body and configured to provide a supply medium;

wherein the basic body extends along a longitudinal axis, the arrangement further comprising:
a component detachably connected or connectable to the basic body, wherein the component comprises two engaging elements, one of the engaging elements having a contour configured to engage into at least one of the two undercuts of the first connection section and another one of the engaging elements having a contour configured to engage into at least one of the two undercuts of the second connection section.

2. The arrangement in accordance with claim 1 , wherein the at least one connection section with the two undercuts has a cross section, in a plane orthogonal to the longitudinal axis of the basic body, the cross section having a shape of a mushroom or of a T or of a C or of a circular segment or of an elliptical segment.

3. The arrangement in accordance with claim 1 , wherein each of the undercuts has a C-shaped or circular segment-shaped or elliptical segment-shaped cross section, in a plane orthogonal to the longitudinal axis of the basic body, each of the undercuts being bent away from the two adjacent outer wall sections.

4. The arrangement in accordance with claim 1 ,
wherein the at least one connection section is mirror symmetrical in relation to a symmetry plane,
wherein the symmetry plane extends parallel to the longitudinal axis of the basic body, and
wherein the symmetry plane cuts in half an angle between the two outer wall sections, the two outer wall sections being adjacent to the connection section.

5. The arrangement in accordance with claim 1 ,
wherein the plurality of outer wall sections comprises a plurality of outer wall sections;
wherein the at least one connection section is one of a plurality of connection sections including at least an additional connection section;
wherein the basic body is columnar with the plurality of outer wall sections and the number of connection sections, each of the plurality of connection sections connecting two outer wall sections,
wherein the at least an additional connection section has an additional connection section undercut, the additional connection section undercut having a form of a channel or a flute or a groove or a sectional rail and extends parallel to the longitudinal axis of the basic body.

6. The arrangement in accordance with claim 1 ,
wherein the basic body has at least one reinforcing structure,
wherein the at least one reinforcing structure increases a wall thickness of one of the outer wall sections connected to the at least one reinforcing structure in an area, the area adjoining the at least one connection section.

7. The arrangement in accordance with claim 6 ,
wherein the basic body further comprises an additional connection section that mechanically connects two respective outer wall sections to each other, the two respective outer wall sections being adjacent to one another and the additional connection section having at least one undercut having a form of a channel or a flute or a groove or a sectional rail and extends parallel to the longitudinal axis of the basic body;
wherein the basic body has a reinforcing structure for the additional connection section that increases a wall thickness of one of the two respective outer wall sections connected to the additional connection section, in an area which adjoins the at least one connection section.

8. The arrangement in accordance with claim 1 , wherein each of the engaging elements engages with one of the undercuts to form a detachable connection, the detachable connection holding the component detachably at the basic body.

9. An arrangement comprising:
a supply system comprising:
a basic body extending along a longitudinal axis, the basic body comprising:
a first outer wall section;
a second outer wall section, the first outer wall section being adjacent to the second outer wall section;
a third outer wall section, the third outer wall section being located adjacent to the first outer wall section; and
a connection section mechanically connecting the first outer wall section and the second outer wall section, the connection section comprising a first undercut and a second undercut, each of the first undercut and the second undercut having a channel form or a flute form or a groove form or a sectional rail form, each of the first undercut and the second undercut extending parallel to the longitudinal axis;
another connection section mechanically connecting the first outer wall section and the third outer wall section, the another connection section comprising another undercut and yet another undercut, each of the another undercut and the yet another undercut having a channel form or a flute form or a groove form or a sectional rail form, each of the another undercut and the yet another undercut extending parallel to the longitudinal axis; and

a supply port flush-mounted in the basic body and configured to provide a supply medium; and

a component detachably connected or connectable to the basic body, wherein the component comprises a first engaging element and a second engaging element, the first engaging element being configured to engage into one of the first undercut and the second undercut, the second engaging element being configured to engage into one of the another undercut and the yet another undercut.

10. The arrangement in accordance with claim 9 , wherein the first engaging element and the first undercut forming a first detachable connection, the second engaging element and the second undercut forming a second detachable connection, the first detachable connection and the second detachable connection holding the component detachably at the basic body.

11. The arrangement in accordance with claim 9 , wherein the connection section comprises an arcuate surface extending from a position adjacent to the first undercut to a position adjacent to the second undercut, arcuate surface being free of recesses.

12. A supply system comprising:
a basic body; and
at least one supply port,
wherein the basic body extends along a longitudinal axis,
wherein the at least one supply port is flush-mounted in the basic body and is configured to provide a supply medium,
wherein the basic body comprises a plurality of outer wall sections and at least one connection section,
wherein the at least one connection section mechanically connects two of the outer wall sections to each other, the two respective outer wall sections being adjacent to one another, and
wherein the at least one connection section has two undercuts, each of the undercuts having a form of a channel or a flute or a groove or a sectional rail and each of the undercuts extending parallel to the longitudinal axis of the basic body, each of the undercuts being spaced apart from one another, each of the undercuts being configured to contact an inner contour of an engaging elemen
