Description
Technical Field
The present invention relates generally to an indirect mobile mixer cartridge (cartucho mezclador), particularly for a single-lever mixer faucet, and more particularly to a mixer cartridge whose configuration provides great stability to the upper rotating element of the cartridge (commonly referred to as the "fitting") and to another internal cartridge element.
Background
It is known to use a mixer cartridge in a single lever mixer faucet mixing valve to mix a cold water inflow and a hot water inflow to regulate the flow rate and temperature of the mixed water in the faucet.
Mixer cartridges fall into two main categories: direct movement and indirect movement.
The indirectly moving mixer cartridge comprises the elements included in the preamble, namely:
-a housing having a protrusion extending inwardly from an inner face of a side wall of the housing;
-an upper element (or "fitting") which is coupled in a rotating manner to the casing and which comprises a fulcrum (fulcro) and an actuating lever mounted to pivot about the fulcrum between a first end position and a second end position;
-a fixed plate which is arranged at least partially inside the housing and which comprises an inlet opening for the separate inflow of cold water and hot water and an outlet opening for the outflow of mixed water;
-a moving element comprising a moving plate arranged inside the housing, which is movable with respect to the fixed plate and which internally defines a mixing chamber open towards the fixed plate, which selectively communicates or blocks partially or totally the communication of said inlet opening with said outlet opening depending on the relative position of the moving plate with respect to the fixed plate, wherein said moving element is coupled in a rotating manner to one end of the actuating rod and can be coupled to said protrusion such that:
-when the actuating lever is in said first end position, the moving element is in a blocking position, in which the moving element is coupled to the protrusion, the moving element is prevented from rotating when the upper element rotates about an axis relative to the housing, and no water flows out; and
-when the actuating lever is pivoted about the fulcrum towards said second end position, the moving element moves over the fixed plate from the blocking position to one of a plurality of release positions, and there is an outflow of mixed water, depending on the relative angle of rotation of the upper element with respect to the housing.
Such an indirect moving mixer cartridge is disclosed in patent US6202693B1, in which a projection extending from the inner face of the side wall of the housing towards the inside defines in this case a recess in which an appendage of the moving element of the cartridge is inserted in the blocking position.
There are also other types of indirectly moving mixer cartridges, in which, contrary to what is disclosed in patent US6202693B1, the recess is defined in the moving element and the projection constitutes an appendage inserted into such recess, preventing its rotation.
Indirect moving mixers have inefficient support during rotational movement due to their geometric complexity. For example, in this type of cartridge, the internal support geometry is typically not structurally compensated and when the actuating rod that actuates the cartridge open is actuated, the internal geometry becomes decompensated (descompensada) and may cause uneven wear in the friction parts, resulting in premature wear of the cartridge.
Such structural decompensation is due to the extremely asymmetric shape of the upper element with respect to a plane comprising the longitudinal axis of the housing, since in order to prevent it from coming into contact with the projection, a portion thereof must be recessed so that it can rotate freely for at least one specific angular sector.
There is a need to provide an alternative to the prior art that provides a solution to the structural decompensation problem, providing an indirect moving mixer cartridge that increases the area of "fitting" contact with the housing, where the "fitting" is more symmetrical, thereby achieving greater stability and longer service life of the cartridge.
Disclosure of Invention
To this end, the invention relates to an indirect mobile mixer cartridge comprising, in a known manner:
-a housing having a protrusion extending inwardly from an inner face of a side wall of the housing;
-an upper element (or "fitting") which is coupled in a rotating manner to the housing and comprises a fulcrum and an actuating lever mounted to pivot about said fulcrum between a first end position and a second end position;
-a fixed plate which is arranged at least partially inside the housing and which comprises an inlet opening for the separate inflow of cold water and hot water and an outlet opening for the outflow of mixed water;
-a moving element comprising a moving plate arranged inside the housing, the moving plate being relatively movable with respect to the fixed plate, and the moving element internally defining a mixing chamber open towards the fixed plate, the mixing chamber selectively communicating, partially or totally, or blocking communication, said inlet opening and said outlet opening depending on the relative position of the moving plate with respect to the fixed plate, wherein said moving element is coupled in a rotating manner to one end of the actuating rod and can be coupled to said protrusion such that:
-when the actuating lever is in said first end position, the moving element is in a blocking position in which the moving element is coupled to the protrusion, the moving element is prevented from rotating when the upper element rotates about an axis relative to the housing, and no water flows out; and
-when the actuating lever is pivoted about the fulcrum towards said second end position, the moving element moves from the blocking position to one of a plurality of release positions above the fixed plate, depending on the relative angle of rotation of the upper element with respect to the housing, and there is an outflow of mixed water.
In contrast to the indirect moving mixer cartridge of the prior art, the indirect moving mixer cartridge proposed by the present invention is characterized in that it comprises a compensation groove defined in said projection or between said projection and an upper wall transversal to said side wall, so that a portion of said upper element is inserted into said compensation groove without blocking the rotation of the upper element, so that different coplanar areas of said portion are arranged within said compensation groove during the rotation of the upper element.
According to one embodiment, said portion of the upper element is constituted by an annular peripheral portion extending radially in a direction transverse to the lateral wall of the casing.
For one embodiment, the above-mentioned annular peripheral portion is divided into two annular peripheral sub-portions by a through opening defined in the plate for the passage of the projection through the through opening during assembly of the upper element inside the housing.
According to one embodiment, the plate comprises two stops delimiting the annular peripheral portion and limiting the rotation of the upper element in two directions when said stops stop against a stop element defined on the inner face of the lateral wall of the casing.
Typically, the housing is a hollow tubular body, wherein said side wall is a first cylindrical wall of said tubular body.
With respect to the above-mentioned upper wall transverse to the side wall, according to one embodiment, this is an annular wall coupling the first cylindrical wall with a second cylindrical wall of smaller diameter than the first cylindrical wall, and through which a portion of the outward projection of the actuation rod passes.

Detailed Description
As can be observed in the figures, in particular in fig. 1, the indirect-moving mixer cartridge of the invention comprises a casing 1 and an upper element 5 or "fitting" coupled in a rotating manner to casing 1 and comprising a fulcrum 8 and an actuating lever 4 mounted to pivot about fulcrum 8 between a first end position and a second end position.
As shown in fig. 1 and 2, the housing 1 is constituted by a hollow tubular body having: a side wall or first cylindrical wall 1 a; a second cylindrical wall 1c of smaller diameter than the first cylindrical wall and through which a portion of the actuating rod 4 projects outwardly; and an upper wall 1b transversal to the side wall 1a and constituted by an annular wall joining the first cylindrical wall 1a and the second cylindrical wall 1 c.
The housing 1 comprises a protrusion P extending inwardly from the inner face of the first cylindrical wall 1a, as can be seen in fig. 1, 2 and 3.
As can be observed in fig. 1, the mixer cartridge further comprises:
a fixed plate 3 arranged inside the housing 1 and comprising an inlet opening (not shown) for the separate inflow of cold and hot water and an outlet opening 10 for the outflow of mixed water;
a moving element comprising a moving plate 2 arranged inside the casing 1 and a moving cover 11 fixed to the moving plate 2, wherein both the moving plate 2 and the moving cover 11 are movable in unison with respect to the fixed plate 3.
As can be observed in fig. 1, the moving plate 2 internally defines a mixing chamber 2a (see also fig. 3) open towards the fixed plate 3, the mixing chamber 2a selectively communicating, partially or totally, or blocking the communication of the inlet opening (not shown) with the outlet opening 10 depending on the relative position of the moving plate 2 with respect to the fixed plate 3, wherein a moving cover 11 is coupled in a rotating manner to one end of the actuating rod 4 and can be attached to the projection P in such a way that:
when the actuating rod 4 is in said first end position, the moving element is in a blocking position, in which it is coupled to the projection P, as shown in fig. 1, is prevented from rotating when the upper element 5 rotates about the axis a with respect to the housing 1, and
when the actuating lever 4 is pivoted about the fulcrum 8 towards said second end position, the mobile element moves from the blocking position to one of a plurality of release positions (not shown) above the fixed plate 3, depending on the relative angle of rotation of the upper element 5 with respect to the casing 1.
As can be observed in fig. 2, for the embodiment shown, the mobile element is coupled to the protrusions P by a coupling arrangement comprising a recess D defined in the mobile cover 11 and the corresponding appendix De, so that in the blocking position the protrusions P are inserted into the recesses D between said appendixes De.
Alternatively (not shown), the projection P defines a recess in which an appendage extending from the mobile cover 11 or from another component of the mobile element is inserted.
As can be observed in the figures, the cartridge of the invention comprises a compensation groove R defined between the projection P and the upper wall 1b transversal to the side wall 1a, so that a portion 5a of the upper element 5 is inserted in the compensation groove R without blocking its rotation, so that during the rotation of the upper element 5 different coplanar areas of the portion 5a are arranged in the compensation groove R.
In this case, the compensation groove R is defined by a through opening that completely traverses the first perimeter wall 1a of the casing 1, as can be observed in fig. 1 and 2, but for another embodiment (not shown), the compensation groove R is defined by a non-through opening defined between the projection P and the upper wall 1b or in the same projection P.
As can be observed in fig. 2, 4, 5 and 6, the portion 5a of the upper element 5 is constituted by an annular peripheral portion which extends radially in a direction transversal to the first cylindrical wall 1a and is divided into two annular peripheral sub-portions 5a1, 5a2 by a notch E which is configured and arranged for passage of the projection P therethrough when the notch E is arranged facing the groove R (as shown in fig. 4) during assembly of the upper element 5 inside the housing 1.
As can also be observed in fig. 2, 4, 5 and 6, the annular peripheral portion 5a formed by the sub-portions 5a1 and 5a2 is angularly delimited by two stops 6, the stops 6 limiting the rotation of the upper element 5 in both directions when the stops 6 are stopped against stop elements 7 defined on the inner face of the first cylindrical wall 1 a. Fig. 6 shows a rotational position of the upper element 5, in which the stop 6 is in contact with the stop element 7, and fig. 5 shows an intermediate rotational position between the rotational positions shown in fig. 4 and 6.
In fig. 5 and 6 it can be observed how the annular peripheral portion 5a (in this case the sub-portion 5a1) passes through the compensation groove R during the rotation of the upper element 5.
The presence of the annular peripheral portion 5a constituted by the sub-portions 5a1 and 5a2 and its insertion into the compensation groove R during the rotation of the "fitting" 5 increases the contact area of the "fitting" 5 with the casing 1 and moreover its symmetry, so that the whole assembly is structurally compensated, thus achieving a great stability and a longer service life of the cartridge, compared to the cartridges of the prior art.
Alterations and modifications may be introduced in the described embodiments by those skilled in the art without departing from the scope of the invention as defined in the appended claims.
