Manual spray head
A manual spray head can be connected with a flexible hose line by means of a coupling that has a ball-and-socket joint inserted between the manual spray head and the hose line. This arrangement not only increases the mobility and flexibility between the manual spray head and the flexible hose line, but also permits twisting of the manual spray head relative to the hose line without fear of unscrewing the screw-type connection or similar coupling provided between the manual spray head and the hose line.
1. A manual spray head arrangement comprising:
a manual spray head;
a flexible hose line; and
a coupling, which couples the manual spray head and the flexible hose line, comprising
a first joint part;
a second joint part; and
a holding element; wherein,
one extremity of said first joint part has an external configuration that is at least partially spherical;
said second joint part has a socket which has an interior configuration that conforms to the external configuration of the first joint part;
said extremity of said first joint part is held in said socket of said second joint part by said holding element, a first end of which has a radially extending partially spherical portion that conforms to and bears against an interior surface configuration of said extremity of said first joint part;
a second end of said holding element, opposite said first end, has a connecting shaft that extends through internal openings of said first and second joint parts, and is configured for attachment to a hose end;
said holding element has an internal conduit that, when connected to said hose end, communicates fluidically with said hose end,
the second joint parts carries a hose stem, which is arranged inside of the flexible hose line, and
a pressing sleeve secures the hose stem to the flexible hose line by the pressing sleeve pressing on an outside of the flexible hose line.
2. A manual spray head having a coupling for connection with a flexible hose line, wherein
the coupling has a ball-and-socket joint that includes first and second joint parts, which are connected with one another and have mutually connected fluid conduits;
the second joint part carries a hose stem, with an internal or external thread being provided on the other joint part;
the first joint part is swivelably held by a universal-ball-joint shaped or substantially spherical front end area thereof, between a form-adapted socket on the second joint part on one side, and a joint head on a holding element provided in the inside cavity of the first joint part, on the other side;
a connecting shaft of the holding element penetrates a through-opening of the first joint part, and acts upon the second joint part;
the holding element mutually connects fluid conduits of the first and second joint parts;
the hose stem is arranged inside of the flexible hose line; and
a pressing sleeve secures the hose stem to the flexible hose line by the pressing sleeve pressing on an outside of the flexible hose line.
3. The manual spray head according to claim 2 , wherein:
the connection of the manual spray head and the hose line comprises a screw-type coupling; and
an external or internal thread on the manual spray head is detachably connectable with an internal or external thread on a hose connection of the hose line.
4. The manual spray head according to claim 3 , wherein the screw-type coupling comprises one of a revolving coupling and a plug-type coupling.
5. The manual spray head according to claim 3 , wherein at least one of the spray head connection and the hose connection has the ball-and-socket joint.
6. The manual spray head according to claim 2 , wherein one of the first and second joint parts has an out-flow side opening with an internal thread into which an external thread on the manual spray head can be screwed.
7. The manual spray head according to claim 2 , wherein:
a sleeve-shaped partial area adjoins the substantially spherical front end area of the first joint part; and
said sleeve-shaped partial area carries the internal thread in its sleeve interior open on the front side.
8. The manual spray head according to claim 7 , wherein at least one of the following applies:
the holding element is configured such that it is screwable into an internal thread in the second joint part by an external thread; and
the sleeve interior of the holding element comprises a noncircular tool working surface.
9. The manual spray head according to claim 8 , wherein the tool working surface comprises a hexagonal socket.
10. The manual spray head according to claim 8 , wherein at least one of the following is true:
the external thread of the holding element can be releasably screwed into the internal thread in the second joint part; and
the holding element is connected into the second joint part in a water-tight manner.
11. The manual spray head according to claim 2 , wherein:
at least one ring-type seal is provided between one of i) the first joint part and the holding element, and ii) the first joint part and the second joint part.
12. The manual spray head according to claim 2 , wherein a ring groove for receiving a ring-type seal is provided at one of i) an outer circumference of the holding element, ii) an inner or outer circumference of the first joint part, and iii) an inner circumference of the second joint part in the area of the joint socket.
13. The manual spray head according to claim 2 , wherein:
a spray head fitting having an outlet tube is assigned to the manual spray head; and
the hose line connected with the manual spray head is guided in the outlet tube such that it can be pulled out against a restoring force.
14. The manual spray head according to claim 13 , wherein the manual spray head is held in a readiness position at the outlet tube, such that the coupling is arranged between the manual spray head and the hose line in the tube interior of the outlet tube.
15. The manual spray head according to claim 2 , wherein at least one ring-type seal is provided between one of i) the first and second joint parts, and ii) the holding element and the first joint part.
