Abstract

The invention relates to a hose coupling ( 5 ) for connecting a flexible hose line ( 3 ) to an adjacent line section ( 6 ). The hose coupling ( 5 ) according to the invention has a coupling housing ( 7 ), which coupling housing ( 7 ) has at least two coupling openings ( 8, 9 ), into each of which a respective coupling mating piece ( 10, 11 ) can be inserted and releasably fixed, which coupling mating pieces ( 10, 11 ) are designed as line ends of a line section, and of which at least one coupling mating piece is provided as the line end of a flexible hose line ( 3 ), wherein the coupling openings ( 8, 9 ) in the coupling housing ( 7 ) are connected to each other.

First claim

1 . A hose coupling ( 5 ) comprising a coupling housing ( 7 ) that has at least two coupling openings ( 8 , 9 ), into each of which a respective coupling mating piece ( 10 , 11 ) is insertable and releasably fixed, said coupling mating pieces ( 10 , 11 ) are line ends of a line section ( 3 , 6 ), and of which at least one of the coupling mating pieces ( 10 , 11 ) is provided as the line end of a flexible hose line ( 3 ), and the coupling openings ( 8 , 9 ) in the coupling housing ( 7 ) are connected to each other.

2 . The hose coupling as claimed in claim 1 , wherein the coupling housing ( 7 ) has housing ends and one of the coupling openings ( 8 , 9 ) is located on a face of each of the housing ends.

3 . The hose coupling as claimed in claim 1 , further comprising a holding element ( 12 , 13 ) assigned to each of the coupling openings ( 8 , 9 ), said holding elements ( 12 , 13 ) are movable between an unlocking position and a locking position, in said locking position the respective holding element ( 12 ; 13 ) fixes an associated one of the coupling mating pieces ( 10 ; 11 ) in the coupling opening ( 8 ; 9 ).

4 . The hose coupling as claimed in claim 3 , wherein the at least one holding element ( 12 , 13 ) is movable from the locking position to the unlocking position by applying pressure counter to a restoring force.

5 . The hose coupling as claimed in claim 4 , wherein the coupling housing ( 7 ) is designed to be grasped in one hand, and configured so that the at least one holding element ( 12 , 13 ) is actuatable with a thumb.

6 . The hose coupling as claimed in claim 3 , wherein the at least one holding element ( 12 , 13 ) comprises a holding slide, which is guided movably between the unlocking position and the locking position in a slide channel ( 28 ) that is oriented transversely with respect to a direction of insertion of the coupling mating piece ( 10 , 11 ) and that passes through the associated coupling opening ( 8 , 9 ).

7 . The hose coupling as claimed in claim 6 , wherein at least one slide end of the holding slide is designed as an actuating button ( 16 , 17 ), and said actuating button ( 16 , 17 ) is arranged for actuation laterally on the coupling housing ( 7 ).

8 . The hose coupling as claimed in claim 6 , on at least one of the holding slides, at least one resilient web ( 30 ) is integrally formed which serves to provide a restoring force and which, when pressure is applied to the holding slide, bears with a free web end against the coupling housing ( 7 ) and is pretensioned via elastic deformation.

9 . The hose coupling as claimed in claim 8 , wherein the restoring force acts on the holding element ( 12 , 13 ) in such a way that, when the pressure is released and the coupling mating piece ( 10 , 11 ) is inserted into the coupling opening ( 8 , 9 ), the holding element ( 12 , 13 ) generates an audible sound upon springing back from the unlocking position to the locking position.

10 . The hose coupling as claimed in claim 3 , wherein on at least one of the coupling mating pieces, an undercut is provided, behind which the associated holding element ( 12 , 13 ) engages in the locking position.

11 . The hose coupling as claimed in claim 10 , wherein on at least one of the coupling mating pieces ( 10 , 11 ), a peripheral annular shoulder ( 20 , 21 ) is provided, which forms the undercut.

12 . The hose coupling as claimed in claim 6 , wherein at least one of the holding slides has a plug-through opening ( 28 ), and a run-on bevel ( 29 ) is provided on at least one of the coupling mating piece ( 10 , 11 ) or on an edge area of the holding slide surrounding the plug-through opening ( 28 ), and by said run-on bevel ( 29 ) an insertion movement of the coupling mating piece ( 10 , 11 ) into the plug-through opening ( 28 ) is converted into a sliding movement of the holding slide from the locking position to the unlocking position.

13 . The hose coupling as claimed in claim 1 , wherein at least one of the coupling housing ( 7 ) is a plastics injection-molded part, or at least one coupling mating piece ( 10 , 11 ) is made from metal.

14 . The hose coupling as claimed in claim 3 , wherein each of the coupling mating pieces ( 10 , 11 ) is provided as a line end of a flexible hose line.

15 . The hose coupling as claimed in claim 1 , wherein at least one sanitary insert cartridge ( 25 ) is inserted in the coupling housing ( 7 ), between the coupling openings ( 8 , 9 ), and the at least one sanitary insert cartridge ( 25 ) is at least one of a flow regulator, a flow restrictor or a check valve.

16 . The hose coupling as claimed in claim 6 , wherein the coupling openings ( 8 , 9 ) are configured differently for insertion of only an assigned and correspondingly shaped one of the coupling mating pieces ( 10 , 11 ).

17 . The hose coupling as claimed in claim 1 , wherein the coupling openings ( 8 , 9 ) are provided for alternate insertion of either of the coupling mating pieces ( 10 , 11 ) that are shaped correspondingly.

18 . The hose coupling as claimed in claim 1 , wherein in an area of at least one of the coupling openings ( 9 ), at least one ring seal is provided which provides a seal between an inner circumference of the coupling housing ( 7 ) and the coupling mating piece ( 11 ) pushed into said coupling opening ( 9 ).

19 . The hose coupling as claimed in claim 18 , wherein the at least one ring seal is secured axially between an annular shoulder ( 32 ) provided on the inner circumference of the coupling housing and an insertion sleeve ( 33 ), said insertion sleeve ( 33 ) is inserted into the coupling opening ( 9 ) and fixed on the inner circumference of the coupling housing ( 7 ).

20 . The hose coupling as claimed in claim 15 , wherein the hose coupling has a color coding as an indicator of the insert cartridges ( 25 ) inserted in the hose coupling, and at least one of the holding elements ( 12 , 13 ) has a paint or dye as color coding on at least a visible side.

21 . The hose coupling as claimed in claim 7 , there are two of the actuating buttons arranged for actuation laterally on the coupling housing in button seats, a stiffening rib ( 35 ) is provided on an outer circumference of the housing, and the stiffening rib ( 35 ) connects the button seats ( 18 , 19 ) to each other.
