Abstract

A water outlet fitting with a handleable water outlet ( 4 ) and with a flexible hose line ( 3 ) which can be connected to the water outlet ( 4 ) via a coupling ( 5 ). A characteristic feature of the water outlet fitting according to the invention is that the coupling ( 5 ), which is provided for connecting the water outlet ( 4 ) and hose line ( 3 ), has a ball-and-socket joint ( 7 ). The ball-and-socket joint ( 7 ) connected between the water outlet ( 4 ) and the hose line ( 3 ) not only increases the mobility and articulation between the water outlet ( 4 ) and the flexible hose line ( 3 ), but the ball-and-socket joint ( 7 ) also permits the water outlet ( 4 ) to be rotated relative to the hose line ( 3 ) without having to be concerned that the screw connection or similar coupling ( 5 ) provided between the water outlet ( 4 ) and hose line ( 3 ) will become undone.

First claim

The invention claimed is:

1. A water outlet fitting comprising:
a manipulable water outlet and
a flexible hose line which is connected to the water outlet via a coupling which has a ball-and-socket joint, which has a first and a second joint part,
said joint parts are connected to each other in an articulated manner and have interconnected liquid passages and of which one of the joint parts bears a hose nipple and an internal or external thread is provided on the other of the joint parts, said internal or external thread being screwable to an internal or external thread on the water outlet,
the first joint part is retained pivotably by a spherical front end region of a wall thereof between a matching joint socket on the second joint part and a joint head on a retaining element provided in an internal cavity of the first joint part,
the retaining element, having a connecting stem, which engages the second joint part, extends through a passage opening in the first joint part and connects the liquid passages of the first joint part and of the second joint part to each other, and
the retaining element is connected to the second joint part via a latching connection wherein the retaining element has, on an outer circumferential side, an annular groove in which an inwardly springable split ring or securing ring is provided, said split ring or securing ring, in a state thereof in which it is sprung out into a use position of the latching connection, protruding into a securing groove on an inner circumference of the second joint part.

2. The water outlet fitting as claimed in claim 1 , wherein one of the joint parts has a coupling opening which is on an outflow side and has the internal thread.

3. The water outlet fitting as claimed in claim 2 , wherein the spherical front end region of the first joint part adjoins a sleeve-shaped subregion which, in a sleeve interior thereof which is open on an end side, bears the internal thread.

4. The water outlet fitting as claimed in claim 3 , wherein the second joint part bears the hose nipple.

5. The water outlet fitting as claimed in claim 1 , wherein at least one annular seal is provided, said annular seal is arranged between the first and the second joint part or between the retaining element and the first joint part.

6. The water outlet fitting as claimed in claim 5 , wherein an annular groove is provided, in which the annular seal is accommodated on an outer circumference of the retaining element, on an inner circumference of the first joint part in a region of the joint socket.

7. The water outlet fitting as claimed in claim 6 , wherein a sealing ring is provided between a free front end of the retaining element and the second joint part.

8. The water outlet fitting as claimed in claim 7 , wherein the joint head of the retaining element has a spherical outer contour, and the annular groove provided on the inner circumference of the first joint part is arranged relative to each other on the retaining element or on the first joint part at least approximately in a region of an equator or of a largest outer circumference of the spherical outer contour of the joint head.
