ABSTRACT:
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to improvements in outflow spouts of faucet sets, in which the corresponding spout base in the device has a tubular spindle to the connection to the power supply.
According to the conventional technique, the said spouts are built as a whole entire piece which provides to the said spout base, generally as a plane support base, in which the tubular spindle is an integrated part of this piece or a false piece screwed or welded to obtain a linked set.
This set normally involves a big mass of material which makes the obtention of its duct work extremely complex, resulting from this, an important design restriction and a significant cost problem.
On the other hand, according to the general conception of the said spouts making, it is almost possible to produce them in plastic materials using common molded techniques which would allow a great reduction in the element costs and an increase in the creation of new designs.
Another inconvenience of the conventional spouts is that when fixing to the element where the integrating faucet set is applied to, the orientation of the said spouts must be taken care when adjusting the fixing elements, for example in a washbasin, it is necessary to fix firmly the spout rightly orientated while adjusting the fixing nut screwed on the edge of the said tubular spindle that stands out behind the appliance.
SUMMARY OF THE INVENTION
As for the aforementioned, it must be stated that it is a basic object of the invention to obtain a new constructive conception to obtain these spouts which require proportionally very reduced mass, only limited to a very thin wall in the overall extension of its outer surface.
In other words, it could be stated that it is necessary that these spout bodies can be assimilated to a solid cover of reduced mass in comparision with the required in the conventional spouts, made of any material, preferably plastic, in whose base it would be possible to develop any design when allowing the application of the most modern molded techniques not only in the exterior but also in the interior.
It is also a basic object of the present invention that even when two or more pieces are required to build the spout body, the said pieces are made of and result from, specially in the event of plastic, no additional operations of adjustment and/or finishing in the building and/or incorporation to the faucet set to which have been assembled; this is so, that can be used as they were built in the matrix.
It is a further object of the present invention to provide an innovate constructive disposition in accordance with herein explained, that enables to develop integrated conjoints of spouts and outflow control valves in the same body of easy assembly and mantenaince and in such conditions that the same spouts can be used indistinctly with or without such valve.
It is of special interest and in relation with the object abovementioned to obtained that in this valve and spout conjoint will be possible to use valves whose operative parts are entirely contained in a replaceable cartridge-head for example that can be easily incorporated to a corresponding housing of the spout body as a part of it, regarding the security of the adjusting of its components independantly of the function as outflow control element.
It is also of special interest that a replaceable cartridge-head valves of any known models can be used and for example a metallic head with an up and down obturator or with ceramic obturator of a ¼ turn can be also used in spout made entirely in plastic.
All of them in such conditions that said valve cartridge-head can be removable and replaceable by another by the user without affecting the spout assembly or its connection to other pieces of the set or its fixing to the support wherein the abovementioned is applied.
Another object of the present invention is to obtain that the spout can be easily fixed to the appliance or other element without taking care of its orientation in such conditions that said orientation can have later adjustment regardless the fixing grade.
