FR 3 063 752 - A1

Element (2) for connecting a mixing valve said to be between axis, in particular 150mm, to the wall expectations for hot and cold water supply, characterized in that it consists of two distinct elements, an eccentric element (13) and a stop element (14), a rear annular part (19) of the eccentric element being intended to be fixed, in particular screwed, to a wall stand and a front annular part (15), axially offset from the rear annular part, being intended to be fixed at the rear of the stop element, while at the front the stop element is intended to be fixed to a water inlet pipe of the mixer , and means are provided (20, 21, 35, 36) for fixing the two elements to one another by plating one against the other, so that their mutual orientation can be chosen from several orientations .

The present invention relates to a connecting element to the wall expectations of a mixing valve said to be between-axis, in particular with 150mm between-axis, in particular of a thermostatic mixing valve, in particular for a shower, a washbasin or a sink , in particular for public places or community, especially in hospitals, as well as an assembly comprising at least one connection element of this kind and a mixing valve.

Conventionally, a thermostatic mixing valve said with a 150mm axis is mounted against a wall by being connected to two wall expectations for supplying hot and cold water respectively. It is necessary for the maintenance and / or repair of the mixer to cut the water supply to the network, which is for communities therefore requires cutting the water for a very large number of mixers even when it is to intervene on only one of them. In addition, to work on the mixer or its connections, the entire mixer must be dismantled, which is a complicated operation, as is reassembly.

Thus we would like to have available a wall-mounted mixing valve with a center line, in particular 150mm, which is simple to assemble and dismantle and whose maintenance can be carried out without having to cut the water network of an entire community, for example of a whole hospital.

According to the invention, a connecting element of a mixing valve said to be between axis, in particular 150 mm, to the wall expectations of hot and cold water supply, is characterized in that it consists of two distinct elements, an element eccentric and a stop element, a rear annular part of the eccentric element being intended to be fixed, in particular screwed, to a wall stand and a front annular part, axially offset from the rear annular part, being intended to be fixed at the rear of the stop element, while at the front the stop element is intended to be fixed to a water inlet pipe of the mixer, and means are provided for fix the two elements to each other by plating one against the other, so that their mutual orientation can be chosen from several orientations.

According to a preferred embodiment, the stop element comprises a stop valve which can pass between a closed position and an open position by means of a screw appearing on the lateral surface of the element d 'stop.

In particular, the stop valve consists of a two-way ball valve, comprising a ball diametrically traversed by a through hole, the ball being integral with the adjusting screw so that the screw can pivot rotates the ball so as to position the hole in two mutually perpendicular orientations.

The present invention also relates to an assembly forming a mixing valve with a center line, in particular 150 mm, for example for a shower, a washbasin or a sink, the device comprising at least one connection element according to the invention, in particular two elements of connection, the or each stop element being screwed by its eccentric element to a wall stand and the front end of the stop element being connected to a respective water inlet pipe of the mixer.

Preferably, the stop element comprises a valve and a valve adjustment screw, the mixer housing comprising at least one through hole opposite the adjustment screw to allow easy access to the screw from the outside. .

Preferably, the front end of the stop element and the respective water inlet duct are fixed to each other by a fixing screw, preferably in the immediate vicinity of the adjusting screw, so that access to the two screws is through the same through hole, the section of which may in particular have an elongated shape.

Preferably, between the wall and the stopcocks, there is an intermediate plate pierced with two circular holes of a shape adapted to receive the annular sections of large diameter of the eccentric elements.

In particular, the form of the plate intermediate adapts to form the wall back of the housing of mixer tap in particular in there fixing, in particular by

through screws or by snap-fastening, in particular by snap-on lugs.

According to a preferred embodiment, the stop element comprises an annular flange intended to abut against the front face of the intermediate plate and either to remain at a distance from the front face of the annular section of the eccentric element, or also to abut against the front face of the annular section of the eccentric element, as a function of the relative position of the eccentric relative to the plate, this relative position depending in particular on the rotation undergone by the rear part of the eccentric .

The play which can thus form between the eccentric element and the annular rim of the stop element makes it possible to perfectly position the mixer with respect to the wall, whatever the rotation undergone by the eccentric element when it is screwed into the wall expectations;

Preferably, at least one hole, in particular a blind hole, emerging at the front surface of the annular section of the eccentric element is in correspondence with at least one slot formed in the annular rim, so that even if the rim is at a distance from the section annular, the respective rod, in particular threaded, of at least one screw passes through the at least one slot to be screwed into the at least one hole, in particular tapped, until its respective head abuts against the peripheral edges of the at least one slot to thus secure the two elements respectively eccentric and stop, in particular by mutual plating of the two elements.

In the drawings, there is shown an embodiment of a device 1 forming a mixing valve with an axis, in particular with a 150mm axis, mounted on a vertical wall. This device 1 forming a mixing valve comprises a pair of stop valves 2 according to one embodiment of

The invention.

The device 1 mixing valve shown is here provided for a shower in a community, in particular a hospital, and we wish to have available a device on which we can intervene for maintenance, repair or replacement without having to cut the water supply to any the community.

In the embodiment shown in the figures, it is a thermostatic mixer comprising a main housing 3 of elongated shape, in particular rectangular as in the figures, but which could have any other shape, in particular circular cylindrical.

The mixer has two rotary knobs 4 and 5 for adjusting the temperature and the flow respectively. Two respectively thermostatic and flow cartridges, in particular a so-called ceramic cartridge, are integrated in the housing between the ducts 7 for entering hot and cold water and a duct 8 for leaving mixed water.

In the fashion of achievement represented, the buttons of settings do protrusion from the front face of housing. We could also arrange them on the above or

laterally without departing from the scope of the invention. Similarly, the water outlet 8 is done from below the housing but could be done on top or laterally without departing from the scope of the invention.

Between the wall 10, and in particular between the wall expectations 11 and 12, which are located opposite the hot and cold water inlets of the network, and the housing 3 of the mixer, it is provided according to the invention to have two taps 2 one opposite each water supply.

A stop valve 2 is shown in particular in Figures 10 to 13, as well as in Figure 1 in exploded form. The valve 2 comprises an eccentric element 13 and an element forming a stop valve or stop element.

The eccentric element 13 has a first annular section 15 open on a front side (before this is understood to mean that this side is facing the user of the device). And closed on the rear side by a rear wall 17 pierced with a hole 18 of hexagonal shape. The hole 18, of dimension smaller than the inner section of the ring 15 has its center which is offset laterally with respect to the center of the inner section of the ring 15. In particular, the center of the hole 18 is approximately near mid distance between the center of the inner circular section of the ring and the inner side face of the ring.

The eccentric element 13 continues, beyond the first section 15, by a second annular section 19 of smaller diameter than that of the first section, in particular with a diameter substantially equal to half the diameter of the first section. The center of the cross section of the small annular section 19 corresponds substantially to the center of the hole 18. The longitudinal axis of the section 19 is thus parallel to the axis of the section 15 while being offset relative to the latter. The section 19 has a thread on its outer surface to allow it to be screwed into a respective wall stand 11, 12.

In the side wall of the first section 15, there are also formed longitudinal threads 20 opening to the front face of the annular section 15 and intended to cooperate with corresponding screws 21 for fixing the stop element 14 to the eccentric element 13. Preferably, a plurality of tappings is provided, distributed regularly along the periphery of the front face of the section 15.

The element 14 forming a shut-off valve comprises a substantially circular cylindrical base body which receives therein a 2-way ball valve 30 comprising a ball traversed along one of its diameters by a circular through hole 32 for traversing. The valve 30 cooperates with an adjustment screw 33, the head of which is accessible from the outside. The screw is integral in rotation with the ball and can be pivoted between two positions at 90 ° rotation from one another. In a first position of the screw, the through hole 32 is substantially arranged with its axis parallel to the axis of the base body of the element 14, so that water can pass, through the hole, through the shut-off valve member, while in the 90 ° rotated position of the adjusting screw 33, the hole is arranged perpendicular to the longitudinal axis of the base body, so that water can no longer pass through through the tap, which is therefore in the stop position.

Between the wall and the stop valves 2, there is disposed an intermediate plate 40 pierced with two circular holes 41 of a shape adapted to receive the annular sections 15 of large diameter of the eccentric elements 13.

The shape of the intermediate plate 40 adapts so as to form the rear wall of the mixer housing, in particular by attaching to it, in particular by means of screws (not shown) or by snap-fastening, in particular by lugs 42 of snap-on.

An annular flange projects laterally from the lateral surface of the base body of the stop member. This rim 35 is pierced with a plurality of slots 36 in the form of an arc of a circle. The annular rim has dimensions, in particular a diameter, which are greater than those of the front face of the eccentric element 13 so that when the rear end of the stop element 14 is introduced into the interior space of the annular section 15 before the eccentric element 13, the rear face of the rim 35 abuts against the front face of the intermediate plate 40 and either remains at a distance from the front face of the annular section 15 of the eccentric element, or also abuts against the front face of the annular section 15 of the eccentric element 13, as a function of the relative position of the eccentric 13 relative to the plate 40, this relative position depending in particular on the rotation undergone by the rear part 19 of the eccentric. However, the blind holes 20 correspond to the slots 36, so that, even if the flange 35 is at a distance from the annular section, the threaded rods of the screws 21 pass through the slots 36 to be screwed into the threads of the holes. 20 blinds until their respective head abuts against the peripheral edges of the slots 36 to thus secure the two elements 13 and 14 respectively eccentric and stop.

The rear part 37 of the base body of the element 14 is adapted to be received in a sealed manner in the front interior space of the section 15, in particular using an O-ring seal 38. The internal shape of the rear part 37 is produced so as to ensure communication for water between the annular section 19 and

the hole of crossing 32 inside tap stop, when this last is in position of passage (position represented to the figures 10 to 12). In addition, at The end front of the body of base there is planned two 39 O-rings for ensure

the seal between the stop element 13 and the inlet ducts 7 of the mixer housing. The connection between the stop element 13 and its respective conduit takes place telescopically, the relative position of the front end of the base body, and in particular of the two O-rings relative to the inner wall of the respective conduit 7, can thus be modified and adjusted by respective sliding of the front end of the base body of the stop element in the duct, in particular as a function of possible misalignments of the wall relative to a perfectly vertical plane, to allow perfect positioning of the mixer with respect to the wall.

In the final installed operating position of the device according to the invention described in the figures, the housing is arranged substantially horizontally, the two eccentric elements being mutually aligned horizontally by being received in the support plate 40 and being at a distance of 150mm from each other (distance measured from center to center), the annular sections of small diameter of the eccentric elements being screwed into the wall expectations 11, 12 and the front ends of the stop elements 14 being received in the rear ends of the hot and cold water inlet pipes from the mixer, a screw 50 ensuring their mutual joining.

In addition, the adjusting screw 33 is oriented with its head down. Two oblong through holes 51 (length in the front-rear direction or perpendicular to the wall) are formed through the bottom wall of the mixer housing to allow access to a screwdriver to act on the adjustment screw of the elements as desired 'stop and / or on the fixing screw 50.

The device is mounted on the wall according to the following steps:

1. screwing of the rear annular sections of the eccentrics in the wall expectations, after having dissociated the eccentric elements from the stop elements (see figure 2).

2. Installation of the support plate by inserting the annular sections before the eccentrics in the holes of complementary shape of the wall plate (see figures 3A and 3B).

3. Adjusting the orientation of the plate by screwing and / or unscrewing the eccentric elements (figure 3C).

4. Fixing of the stop elements on the associated eccentric elements with fixing by the screws 21 (figure 4).

5. Tighten the fixing screws 21 to put the stop element on the support plate (see Figure 5). Thus, within the limit of two unscrewing turns to orient the support plate, the stop elements are always at the same distance from the bearing face of the support plate.

6. Mount the mixer on the stop elements, making the front ends of the stop elements penetrate into the hot and cold water inlet pipes of the mixer respectively (figure 6 and 7) and screw the screw solidarity 50.
