The present invention refers to a universal hydraulic connection system.

In particular, the present invention refers to a universal hydraulic connection system comprising a mixer which can be adapted both to the type of required fastening, such as a fixed wall, a piping, a shelf, etc. and to the type of user, such as a wash-basing, a tank, a shower, a vessel, a fountain, etc.

Traditionally, metal or plastic mixers comprising quick connection systems of the inlet and outlet piping allow an adaptation with respect to piping with different diameter in order to connect taps of a certain user.

The state of the art of hydraulic mixers and taps of the universal type is given by several patents .

For example, Utility Model CN2318488Y discloses a universal water supplying valve comprising a water inlet pipe, a valve and an oulet pipe. The water discharge pipe is connected with a rigid undulated pipe. The water outlet angle of the universal water supplying valve can be changed at will .

Document US8365320B1 discloses a universal discharge valve system comprising a connector adapted to house different connections of different types of discharge valves.

Patent application US20140261808A1 discloses a universal valve body comprising a front face having a circular opening to receive a valve cartridge, a rear face, a frustum-of-cone shaped side wall connecting the front face to the rear face, a prima inlet opening and a first outlet opening arranged in the side wall.

Document US6422520B1 discloses a universal assembling bracket configured for assembling a mixer directly prepared in the rear part of a wall made of glass fibre of a shower. The assembling bracket is connected to a plurality of U-shaped clips which engage a plurality of rectangular openings placed on the bracket body. The assembling bracket comprises a plurality of forked rear projections. The configuration of the forked projections allows fastening a plurality of copper pipes of the mixing valve.

Object of the present invention is solving the above prior art problem, by providing a universal hydraulic connection system which allows removably connecting a control mixer to a supporting device, keeping the hydraulic connection of such control mixer with a hydraulic network.

Another object of the present invention is providing a universal hydraulic connection system which is simple to build, easy to manage as production and warehouse.

A further object is providing a universal hydraulic connection system which can be made through an extremely simple manufacturing process.

The above and other objects and advantages of the invention, as will appear from the following description, are obtained with a universal hydraulic connection system as claimed in claim 1.

Preferred embodiments and non-trivial variations of the present invention are the subject matter of the dependent claims.

It is intended that all enclosed claims are an integral part of the present description.

It will be immediately obvious that numerous variations and modifications (for example related to shape, sizes, arrangements and parts with equivalent f nctionality) can be made to what is described, without departing from the scope of the invention as appears from the enclosed claims.

The present invention will be better described by some preferred embodiments thereof, provided as a non-limiting example, with reference to the enclosed drawings, in which:

Figures 11 and 12 show a perspective view of a fourth preferred embodiment of the universal hydraulic connection system according to the present invention;

Figures 13 and 14 show a perspective view of a fifth preferred embodiment of the universal hydraulic connection system according to the present invention;

Figures 15 to 21 show a perspective view of several combinations of previous embodiments of the universal hydraulic connection system according to the present invention; and

- Figures 22, 23 and 24 show several interchangeable connection users of the universal hydraulic connection system according to the present invention.

With reference to Figures 1 to 5, it is possible to note that a universal hydraulic connection system according to the present invention comprises at least one control mixer 1, interchangeable inlet connectors 2 and outlet connectors 3 for a connection to a hydraulic network and at least one supporting device 4.

Moreover, the inlet connector 2 can be of the type with single entry (not shown, commonly for cold water only) , or of the type with double entry (shown in Figure 1, with an entry for cold water and one for hot water) , in order to perform the function of mixer.

Advantageously, the system according to the present invention further comprises a quick connection system which allows removably connecting the control mixer 1 to the supporting device 4 though keeping the hydraulic connection of the control mixer 1 with respect to the hydraulic network .

In particular, the quick connection system is composed of a grooved profile 21, 31, of at least one of the interchangeable inlet connector 2 and outlet connector 3 and of a shaped guide 41 of such supporting device 4. In this way, the quick connection device allows sliding and blocking the control mixer 1 with respect to such supporting device 4.

With reference to Figures 4 to 8, it is possible to note that the supporting device 4 can comprise a shelf 42 to allow resting objects thereon.

With reference to Figures 9, 10, 13, 14, 17, 18 and 21, it is possible to note that the supporting device 4 can comprise a flange 43 adapted to support at least a tap 5 hydraulically connected to the control mixer 1.

In particular, with reference to Figure 10, it is possible to note that the flange 43 can be equipped with at least one longitudinal groove and the tap 5 can be of the type composed of a pipe equipped with a series of holes to allow addressing a jet of water through such groove obtained along such flange 43.

With reference to Figures 11 and 12, it is possible to note that the supporting device 4 can further comprise at least one spring-type claw 44 to allow supporting and blocking the control mixer 1, by means of any hold which can be reached by the spring-type claw 44 itself.

With reference to Figures 13 to 21, it is possible to note that the supporting device 4 can comprise at least one fastening flange 45 adapted to support at least one hydraulic pipe 6.

With reference to Figures 22 to 24, it is possible to note that the tap 5 can be composed of a water delivering element 51, 52, 53 of an interchangeable type with respect to the control mixer 1.

From the construction point of view, the supporting device 4 can be of the type obtained from shaped and bent sheets.

The universal hydraulic connection system of the present invention as described above thereby allows obtaining the stated objects.

In particular, the control mixer 1 connected to a hydraulic network through interchangeable inlet and outlet connectors can also be removably connected to the supporting device. In this way, also the mixer, as already used for taps, can assume a standardized shape which can be easily applied in any point of the hydraulic network. The chance of using a single type of mixer allows greatly reducing the production costs, due to the management of a reduced number of die-casting dies, for example.

A removable connection of the mixer with respect to a hydraulic network allows defining several types of use as explained in the description of the present invention.

In fact, the supporting device adapted to removably connect the mixer to the hydraulic network is adapted to perform several additional functions, under several combinations.

In particular, such supporting device can comprise one or more of the following elements:

a shelf for resting objects thereon;

a connection flange of at least one tap;

a fastening flange of sections of hydraulic pipe;

a spring-type claw to allow blocking the mixer in different environments.

The universal hydraulic connection system of the present invention further allows making a supporting device with a pleasant, in addition to functional design.
