DESCRIPTION:
BRIEF SUMMARY
The invention relates to a wall supply for connection of a fitting to a water system, with a wall supply piece which has a wall-side supply part with an inlet channel and a fitting-side supply part with an outlet channel, the inlet channel and the outlet channel preferably being arranged eccentrically offset to one another.
Wall supplies are used to connect the hot and cold water installation lines of the water system to a fitting. Conventionally the inlet channel and the outlet channel in the wall supply piece are arranged axially parallel eccentrically offset to one another. In practice these wall supplies are therefore called "S-supplies". The eccentric arrangement of the inlet and outlet channel can balance inaccuracies in the distance of the supplies of the hot and cold water installation lines provided in the installation wall when mounting the fitting. By turning the pertinent wall supply pieces it is possible to mount the fitting exactly when the distance of the supplies of the installation lines deviates somewhat from the setpoint.
A water supply of the aforementioned type is already known from DE-U-67 51 160 and both on its wall side and also on its fitting-side supply part it has an outside thread for connection to the supplies of the installation lines or the fitting. Corresponding to the outside thread on the fitting-side supply part of the wall supply piece there is a union nut with an inside thread on the fitting on the hot and cold water delivery. The known screw connection between the wall supply and the fitting takes up a comparatively large amount of space as a result of the respective union nuts on the hot and cold water delivery so that a fitting which has been connected via a known wall supply projects accordingly away from the installation wall.
The object of this invention is to make available a wall supply for connection of a fitting to a water system, the connection between the wall supply and the fitting taking up as little space as possible and at the same time it can be easily produced.
This object is achieved as claimed in the invention in a wall supply of the initially mentioned type in that there is a flange which has threaded holes for connection of the wall supply to the fitting via mounting screws. Based on the aforementioned flange connection it is now possible for the connection between the wall supply and the fitting proceeding from the installation wall to have only a very small extension. This is especially advantageous if a fitting is to be made available which proceeding from the installation wall has only a very small construction depth. In addition to the small attainable construction depth of a fitting which has been connected via a wall supply as claimed in the invention, the flange connection moreover offers the advantage that it can be produced very easily, since to do so only two mounting screws need be screwed in.
Other features, advantages and possible applications of this invention follow from the dependent claims and the following description of embodiments using the drawings and the drawings themselves.
FIG. 1 shows a side view, partially in cross section, of a wall supply as claimed in the invention,
FIG. 2 shows one view of the wall supply from FIG. 1 in the direction of the arrow II from FIG. 1, but without the mounting screws,
FIG. 3 shows a side view of part of a fitting with a wall supply as claimed in the invention,
FIG. 4 shows an overhead view of a fitting with two water supplies as claimed in the invention, and
FIG. 5 shows a view of a fitting from FIG. 4 in the direction of the arrow V from FIG. 4.
The individual figures show a wall supply 1 for connection of a fitting 2 to a water system which includes the hot and cold water installation lines which are not shown here and which end in the corresponding supplies to which then the fitting 2 is connected via the wall supplies 1. The wall supply 1 itself has a wall supply piece 3 which is provided with a wall-side supply part 4 and a fitting-side supply part 5. In the wall-side supply part 4 the
