Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims convention priority from German
patent application no. 20 2004 005 561.9, with a filing date of
Apr. 7, 2004. The specification and drawing of the German patent
application are specifically hereby incorporated herein by
reference.
BACKGROUND OF THE INVENTION
[0002] The present invention relates to a water discharge fitting
having a foldable water discharge pipe, the water discharge pipe
being rotatably connected to a fitting body through a connecting
member. The invention further relates to a one-lever mixer,
especially for installation in trailers and caravans.
[0003] Water discharge fittings having a foldable water discharge
pipe are known and are installed especially in trailers and
caravans. In caravans, trailers and campers, there is often the
necessity of inserting very low fittings in sinks with foldable
glass cover. Especially, the thus used fittings are usually not
allowed to exceed the height of 40 mm. However, the known previous
fittings have the disadvantage that fatigue of the discharge pipe
connection occurs after certain time of use or even at different
temperatures. This results in the discharge automatically lowering
or being thrown upwards upon turning on the water flow. Up to now,
the strength of the discharge has been achieved by the friction of
two plastic parts or by insertion of large-dimensioned O-rings.
However, also with these solutions, again and again, problems with
respect to strength of the discharge pipe connection occur.
SUMMARY OF THE INVENTION
[0004] Therefore, it is the object of the present invention to
provide a generic water discharge fitting, which ensures increased
strength of a discharge pipe connection of a foldable water
discharge pipe.
[0005] This object is solved by a water discharge fitting having
the features of claim 1.
[0006] Advantageous developments are described in the dependent
claims.
[0007] A water discharge fitting according to the invention has a
foldable water discharge pipe, the water discharge pipe being
rotatably connected to a fitting body through a connecting member,
and the connecting member and the fitting body being formed locking
with each other, wherein the locking has at least one locking step.
Due to the possibility of locking the connecting member and the
fitting body in at least one locking step, it is ensured that the
water discharge pipe can be securely maintained in an operational
position or is securely maintained in a folded rest position or
transporting position. Therein, for locking the connecting member
and the fitting body, according to an embodiment according to the
invention, at least one projection can be formed inside the fitting
body, wherein the projection is insertable and lockable in at least
one recess formed inside the connecting member.
[0008] However, in another embodiment according to the invention,
it is also possible that at least one projection is formed inside
the connecting member, wherein the projection is insertable and
lockable in at least one recess formed inside the fitting body. By
locking the connecting member and the fitting body, on the one
hand, the strength of the discharge pipe connection is ensured, and
also on the other hand, for example during travel of a trailer,
there cannot arise any rattling noises due to a loose discharge
pipe.
[0009] In another advantageous development of the invention, at
least two recesses are circularly disposed. Therein, it is possible
to dispose a plurality of recesses radially equally spaced apart.
Thereby, on the one hand, it is ensured to bring the water
discharge pipe without problem from a rest position into an
operational position or vice versa, and on the other hand, by a
plurality of recesses, the inclination angle of the water discharge
pipe can be varied nearly in any manner.
[0010] In another advantageous development of the invention, the
projection or projections is or are disposed resiliently,
respectively. Thereby, it is possible, despite the locking or
toothing of the connecting member with the fitting body, to
transfer the water discharge pipe into the corresponding locking
positions without too high effort. One possibility of development
is the formation of the projection or projections from resilient
material. Further, it is possible that the projection and the
recesses are each formed rounded.
[0011] A one-lever mixer according to the invention, especially for
installation in trailers and caravans, has a water discharge
fitting according to the previously described embodiments.
[0012] Other objects, features and advantages of the present
invention will become apparent upon reading and understanding this
specification, taken in conjunction with the accompanying
drawings.

DETAILED DESCRIPTION OF SOME PREFERRED EMBODIMENTS
[0018] FIG. 1 shows in a schematic view a water discharge fitting
10 according to a first embodiment. The water discharge fitting has
a foldable water discharge pipe 12, which is rotatably connected to
a fitting body 16 through a connecting member 14. The connecting
member 14 is formed cylindrically and has a housing 28 with a
housing opening 30. The housing opening 30 serves for detachably
inserting the water discharge pipe 12. The fitting body 16 is also
formed cylindrically in the region of connection to the connecting
member 14, and additionally has water supplies 26 as well as a
securing device 42 with a male thread for securing the water
discharge fitting 10. Additionally, a turning on/off device 22
having a lever 24 adjoins to the fitting body 16. In the
illustrated embodiment, its a so-called one-lever mixer.
[0019] One recognizes that the connecting member 14 and the fitting
body 16 are formed locking with each other, wherein the locking has
two locking steps. Therein, inside the fitting body 16, a
projection 18 is formed, wherein the projection 18 is insertable
and lockable in two recesses formed inside the connecting member
14. Especially, the type of locking becomes clear from the detail
drawing X. One recognizes that the two recesses 20 are circular and
disposed in an angular distance of 90.degree.. Further, one
recognizes that the projection 18 is placed centrally on a spring
member consisting of the spring arms 38 and 40. Additionally, a
frame 34 is formed inside the connecting member 14, which forms a
sleeve 32 for receiving a connecting pin 36 of the fitting body 16.
Therein, the frame 34 is connected to the inner circumference of
the housing 28 through legs 44. The water discharge pipe 12, the
connecting member 14, the fitting body 16 as well as the turning
