Abstract

A hose coupling is sleeve-shaped form and which, at at least one coupling end, has a connector with a retention profiling provided on the outer circumference at least in one connector subregion, onto which at least one profiled coupling end a hose end of a flexible hose can be pushed. The hose coupling according to the invention is characterized in that the retention profiling is formed by at least one retention groove which is provided on the outer circumference of the connector and which has groove long sides oriented in the connector circumferential direction and groove narrow sides oriented in the connector longitudinal direction.

First claim

What is claimed is:

1. A hose coupling ( 1 ) comprising a sleeve-shaped form and which, at at least one coupling end, has a connector ( 3 ) with a retention profiling provided on the outer circumference at least in one connector subregion, onto which coupling end a hose end ( 4 ) of a flexible hose ( 2 ) can be pushed, wherein the retention profiling is formed by at least one retention groove ( 5 ) which is provided on the outer circumference of the connector ( 3 ) and which has groove long sides ( 8 , 9 ) oriented in the connector circumferential direction and groove narrow sides ( 6 , 7 ) oriented in the connector longitudinal direction, wherein connector sections ( 24 ) of the connector ( 3 ) which adjoin the groove long sides ( 8 , 9 ) and/or separate the groove long sides ( 8 , 9 ) of the retention grooves ( 5 ), arranged on adjacent circumferential lines from one another project outward in the manner of ribs and taper in the radially outward direction, wherein the connector has a groove-free face end region ( 13 ) on the outer circumference, and wherein the groove-free face end region ( 13 ) of the connector ( 3 ) is in the form of a push-on cone and, tapers conically toward the face end.

2. The hose coupling as claimed in claim 1 , wherein the connector ( 3 ) has, in a connector subregion facing away from the coupling end, a retention profiling which is formed by the at least one retention groove ( 5 ) provided on the outer circumference of the connector, which retention groove has groove long sides ( 8 , 9 ) oriented in the connector circumferential direction and groove narrow sides ( 6 , 7 ) oriented in the connector longitudinal direction, and wherein at least one retention rib ( 23 ) oriented in the connector circumferential direction is provided between said retention profiling and the coupling end.

3. The hose coupling as claimed in claim 2 , wherein the at least one retention rib ( 23 ) is of encircling form, or has interruptions at preferably uniform intervals.

4. The hose coupling as claimed in claim 2 , wherein at least two retention ribs ( 23 ) which are spaced apart from one another are provided between the retention profiling and the coupling end.

5. The hose coupling as claimed in claim 4 , wherein the retention grooves ( 5 ) arranged on adjacent circumferential lines are provided in lines arranged axially parallel to the connector longitudinal axis.

6. The hose coupling as claimed in claim 4 , wherein the retention grooves ( 5 ) arranged on adjacent circumferential lines are arranged offset with respect to one another.

7. The hose coupling as claimed in claim 6 , wherein the retention grooves ( 5 ) arranged on adjacent circumferential lines are arranged offset with respect to one another such that adjacent groove narrow sides ( 6 , 7 ) of retention grooves ( 5 ) arranged on a common circumferential line are arranged approximately centrally with respect to a retention groove ( 5 ) provided on an adjacent circumferential line.

8. The hose coupling as claimed in claim 1 , wherein the at least one retention groove ( 5 ) has a groove base ( 11 ) which is of flat, concave or convex form.

9. The hose coupling as claimed in claim 1 , wherein the retention profiling has at least two retention grooves ( 5 ), the adjacent groove narrow sides ( 6 , 7 ) of which are spaced apart from one another.

10. The hose coupling as claimed in claim 1 , wherein the retention profiling has at least two retention grooves ( 5 ) arranged approximately on a common circumferential line.

11. The hose coupling as claimed in claim 10 , wherein the retention grooves ( 5 ) arranged on a common circumferential line are arranged so as to be distributed over the connector circumference at uniform intervals.

12. The hose coupling as claimed in claim 10 , wherein the retention grooves ( 5 ) arranged on a common circumferential line define a substantially triangular, square, hexagonal or polygonal connector cross section.

13. The hose coupling as claimed in claim 1 , wherein, in at least one subregion of the connector ( 3 ), retention grooves ( 5 ) are provided so as to be arranged on at least two circumferential lines, and wherein the groove long sides ( 8 , 9 ), which face toward one another, of the retention grooves ( 5 ) arranged on adjacent circumferential lines are spaced apart from one another.

14. The hose coupling as claimed in claim 1 , wherein the hose end ( 4 ) that has been pushed onto the profiled coupling end is retained thereon by means of a crimp sleeve ( 10 ) which encompasses the hose end ( 4 ).

15. A hose coupling ( 1 ) comprising a sleeve-shaped form and which, at at least one coupling end, has a connector ( 3 ) with a retention profiling provided on the outer circumference at least in one connector subregion, onto which coupling end a hose end ( 4 ) of a flexible hose ( 2 ) can be pushed, wherein the retention profiling is formed by at least one retention groove ( 5 ) which is provided on the outer circumference of the connector ( 3 ) and which has groove long sides ( 8 , 9 ) oriented in the connector circumferential direction and groove narrow sides ( 6 , 7 ) oriented in the connector longitudinal direction, wherein connector sections ( 24 ) of the connector ( 3 ) which adjoin the groove long sides ( 8 , 9 ) and/or separate the groove long sides ( 8 , 9 ) of the retention grooves ( 5 ), arranged on adjacent circumferential lines from one another project outward in the manner of ribs and taper in the radially outward direction, wherein the connector ( 3 ) has, in a connector subregion facing away from the coupling end, a retention profiling which is formed by at least one retention groove ( 5 ) provided on the outer circumference of the connector, which retention groove has groove long sides ( 8 , 9 ) oriented in the connector circumferential direction and groove narrow sides ( 6 , 7 ) oriented in the connector longitudinal direction, and wherein at least one retention rib ( 23 ) oriented in the connector circumferential direction is provided between said retention profiling and the coupling end, the at least one retention rib ( 23 ) and the connector sections ( 24 ) having equal diameters.
