Sanitary Fitting

A sanitary fitting contains a fitting housing with a basic element in the form of a straight circular cylinder with an open underside. An interior with a straight-line central axis is formed inside the basic element, into which and out of which lines pass through the open underside. The basic element has a branch which likewise has the form of a circular cylinder with an open outer face. The interior of the branch merges into the interior of the basic element. The branch contains a receptacle for a mixer cartridge. A connecting element inserted in the branch is used to make the water-carrying connection between the lines inside the basic element and the mixer cartridge inside the branch. The connecting element consists of plastic.

DETAILED DESCRIPTION

FIG. 1shows on the left the fitting housing1which has the form of a straight circular cylinder with a flat underside and a flat upper side2. The fitting housing1has a housing section3forming a branch. The branch3likewise has the shape of a straight circular cylinder. The branch is vertical to the longitudinal axis of the fitting housing1.

Supply lines4can pass through the open underside of the fitting housing1into the interior of the fitting housing, as can a line5leading away from it which forms a loop and is then passed as a line5through the fitting housing1upwards and out of the latter.

The housing section3has an end face open in one plane. A connecting element7is intended for insertion through this open end face6and has in its left-hand area inFIG. 1plug-in connections8,9for the supply lines4and the discharging line5. At its end shown on the right inFIG. 1, the connecting element is designed as a plate element10whose outer diameter approximately corresponds to the internal diameter of the housing section3.

This plate element10is designed for interaction with a mixer cartridge11which contains the mixing system proper and is likewise intended and designed for insertion into the housing section3forming a receptacle12. A clamping nut13is intended for fastening the mixer cartridge11in the receptacle12, and then a rosette14covers it. The actuating lever15projecting out of the mixer cartridge11also projects through the rosette14. An actuating handle16is screwed onto the lever, covers the actuating device with a cap17and is provided with a projecting lever18. A user can grip the lever18to actuate the mixer cartridge11.

As can be seen fromFIGS. 1 and 2and from the view inFIG. 3for the variant therein, the two plug-in connections8for the supply lines4are arranged in a transverse plane next to one another, and the plug-in connection9for the discharging line5is arranged in front of this transverse plane closer towards the side of the mixer cartridge11. The plug-in connection9for the discharging line5is thus arranged on that side of the plug-in connections8for the supply lines which is opposite the interior22of the fitting housing1. This allows the curvature for the discharging hose line5, at its lower reversing end from which it is routed upwards behind the connecting element7and through the interior22of the fitting housing1, to be kept lower than in designs in which the plug-in connection9is arranged in the same transverse plane as the plug-in connections8or closer towards the interior22of the fitting housing1than the plug-in connections8.

When the connecting element is inserted, the plate element10contacts a shoulder19of the receptacle provided at that end of the housing section facing the interior of the fitting housing1. This is shown inFIG. 2. The mixer cartridge11is in direct contact with the connecting element7. The clamping nut13is screwed into a female thread of the housing section3and forces the mixer cartridge11against the plate element10of the connecting element7. The lines4,5are inserted with their plug-in nipples20in that part of the connecting element7projecting into an interior22of the fitting housing1. The part of the connecting element7projecting into the interior22of the fitting housing1leaves sufficient space relative to the opposite wall of the interior22that the line5can be passed through it.

In the embodiment shown inFIG. 1andFIG. 2, a longitudinal axis of the housing section3forming the branch is vertical to the indicated longitudinal axis21of the fitting housing1. In the embodiment now shown in the following figures, the longitudinal axis of the housing section22forming the branch is oblique relative to the longitudinal axis21of the fitting housing1. The result of this is that a different connecting element27is used. This is shown inFIG. 3andFIG. 4. The part of the connecting element27projecting into the interior22of the fitting housing1has in turn plug-in connections for the lines4,5, as shown in the example inFIGS. 1 and 2. Its plate element30is now at an angle relative to the longitudinal axis21of the fitting housing1such that the surface it forms is in a plane vertical to the longitudinal axis of the housing section23forming the branch. The oblique angle is preferably between 45° and 90°, more preferably between about 65° and about 85°.

Here too the mixer cartridge11directly contacts the plate element30of the connecting element27.

In both embodiments, the connecting element7or27is of plastic, so that the water passing through the fitting does not come into contact with metal at any point.

InFIG. 3an alignment aid24can be discerned between the connecting element27and the mixer cartridge11which interacts with openings25in the plate element10of the connecting element27.

The connection between the hoses forming the supply lines4,5and the mixer cartridge11is achieved by ducts inside the connecting element, of which one duct26can be seen inFIG. 4.

Both embodiments show a sanitary fitting having a fitting housing with a basic element in the form of a straight circular cylinder with an open underside. An interior with a straight-line central axis is formed inside the basic element, into which and out of which lines pass through the open underside. The basic element has a branch which likewise has the form of a circular cylinder with an open outer face. The interior of the branch merges into the interior of the basic element. The branch contains a receptacle for a mixer cartridge. A connecting element inserted in the branch is used to make the water-carrying connection between the lines inside the basic element and the mixer cartridge inside the branch. The connecting element consists of plastic.
