Definitions

  • the present invention relates to an adaptation kit for flushing valves of flush tanks, in particular ceramic flush tanks, for sanitary appliances.
  • a flush tank has a basin-shaped body defining a water tank and closed at the top by a lid (possibly removable to access the inside of the tank), and a flushing valve housed inside the tank; the flushing valve selectively opens/closes an outlet hole, normally formed in a bottom wall of the tank and communicating with a sanitary bowl to be flushed by a flushing pipe.
  • the flushing valve is fastened to the bottom wall by means of a so-called drain, consisting of a cylindrical lower end portion of a support structure for the flushing valve and shaped so as to engage with a collar, which projects from the bottom wall of the tank and delimits the outlet hole.
  • a so-called drain consisting of a cylindrical lower end portion of a support structure for the flushing valve and shaped so as to engage with a collar, which projects from the bottom wall of the tank and delimits the outlet hole.
  • Flush tanks of different types may require flushing valves having specifically designed connecting parts (a drain and related fastening means), resulting in the need to provide different, non-interchangeable models of flushing valves on different flush tanks.
  • Flush tanks for these two types of sanitary appliances (often referred to, for the sake of simplicity, as “one-piece” tanks and “two-piece” tanks) generally require flushing valves equipped with different connectors (coupling members).
  • US2010212079A1 describes an adaptation kit for flushing valves, comprising a flushing valve and a pair of adapter elements; the adapter elements have substantially identical upper portions configured for coupling to a fitting of the flushing valve, and bottom portions, which instead have outer diameters different from one another.
  • the flushing valve can be equipped with one or the other of the adapter elements and thus be installed in tanks having different sized drain holes.
  • the coupling between the adapter elements and the fitting of the flushing valve is not entirely satisfactory.
  • the present invention relates to an adaptation kit for flushing valves of flush tanks, in particular ceramic flush tanks, as defined in appended claim 1, and for its preferred aspects in the dependent claims.
  • the adaptation kit of the invention allows, in a simple and quick way, a flushing valve to be adapted for use in different flush tanks, and specifically in "one-piece” and “two-piece” ceramic flush tanks, by using very few components, which are simple and inexpensive to manufacture and easy and quick to install.
  • number 1 indicates, as a whole, an adaptation kit for a flushing valve 2 (essentially known per se and only shown partially and in a very schematic way with a broken line in Figure 1 ) for flush tanks, in particular (but not exclusively) for ceramic flush tanks.
  • the adaptation kit 1 serves to adapt the flushing valve 2 (not shown in Figure 2 ) for use in two or more different flush tanks 3A, 3B, such as for example (but not only) a "one-piece” ceramic flush tank 3A and a "two-piece” ceramic flush tank 3B.
  • the adaptation kit 1 comprises a support 4, shaped so as to receive and support a flushing valve 2, and a set of two or more adapter elements 5A, 5B, provided with respective fastening members 6 for selectively fastening one of the adapter elements 5A, 5B to the support 4.
  • adapter elements 5A, 5B are described below, but it is understood that the adaptation kit 1 may include a different number of adapter elements.
  • the support 4 which is preferably made of a single monolithic piece, extends along an axis A (vertical in use) and comprises an upper frame portion 7 and a lower collar portion 8, which are connected by longitudinal ribs 9 (substantially parallel to the axis A).
  • the frame portion 7 has a support seat 10 shaped so as to receive and support, in use, the flushing valve 2.
  • the frame portion 7 has an annular shape around the axis A and the support seat 10 is substantially cylindrical around the axis A and is provided with a bayonet fitting 11 shaped to cooperate, in use, with hooking members 12 of the flushing valve 2, in particular carried by a base body 13 of the flushing valve 2 so as to fasten the base body 13 of the flushing valve 2 to the frame portion 7 of the support 4, in the support seat 10.
  • the bayonet fitting 11 comprises a pair of hooking seats 14 positioned diametrically opposite to each other on a substantially annular side wall 15 of the frame portion 7; each hooking seat 14 comprises a circumferential slot 16 along the wall 15 and an axial groove 17 (parallel to the axis A) orthogonal to the slot 16; the hooking seats 14 are shaped so as to receive respective hooking members 12, in this case shaped as radially extending radial pins diametrically opposite the base body 13.
  • the hooking members 12 are axially insertable (by moving the flushing valve 2 along the axis A) in the respective grooves 17 and then, by rotation of the flushing valve 2 about the axis A, in the respective slots 16, with which they preferably engage through a click-on connection.
  • the frame portion 7 and the collar portion 8 are located at respective opposite axial ends 18, 19 of the support 4, which, in use, are the upper end and the lower end, respectively.
  • the collar portion 8 has a substantially tubular shape about the axis A and comprises a substantially cylindrical side wall 21 and two radially outer flanges 22, 23 at the axial ends, which, in use, are the upper flange and the lower flange, respectively.
  • the upper flange 22 is provided with an annular sealing seat 24, which delimits a drain hole 25 and cooperates, in use, with a shutter 26 of the flushing valve 2.
  • the shutter 26, for example, according to a known and common configuration, is movable, (in particular, axially slidable along the axis A) in the base body 13 to selectively open/close the drain hole 25.
  • the lower flange 23, located at the bottom axial end 19 of the support 4, has ( Figure 3 ) at least one fastening seat 27, arranged on a perimetric edge 28 of the flange 23.
  • the flange 23 has a plurality of fastening seats 27, arranged on the edge 28 and angularly spaced apart from one another along the edge 28 about the axis A.
  • the flange 23 has two diametrically opposite fastening seats 27.
  • Each fastening seat 27 is defined by an edge portion 29 of the perimetric edge 28 having a substantially flat face 30 (upper face in use) perpendicular to the axis A.
  • Each fastening seat 27 is associated with an access cavity 31, adjacent to the fastening seat 27 along the edge 28 and defined by a radial recess formed in the edge 28.
  • each fastening seat 27 is comprised between a projection 32, which projects axially from the face 30 and extends radially thereon, adjacent to the cavity 31; and a circumferential shoulder 33 which projects axially from the face 30.
  • the collar portion 8 also comprises ( Figure 4 ) an end collar 34, which projects from the flange 23 on the opposite side of the side wall 21 and the flange 22, at the end 19 of the support 4; the collar 34 is preferably provided with a circumferential groove 35 housing a radial sealing ring 36.
  • the ribs 9 connect the frame portion 7 and the collar portion 8 and laterally delimit radial openings 37 that are located between the frame portion 7 and the collar portion 8.
  • the support 4 also comprises an auxiliary pipe 38, extending substantially parallel to the axis A next to the frame portion 7 and the collar portion 8; the pipe 38 is connected to the collar portion 8 by means of a connecting portion 39, which, for example, can be curved or inclined, which communicates with the inside of the collar portion 8 through a passage formed in the side wall 21.
  • the pipe 38 serves as an overflow pipe in the event that the flushing valve 2 does not have a built-in overflow pipe. It is understood that the support 4 may not have the pipe 38, for example if the flushing valve is provided with a built-in overflow pipe.
  • the adapter elements 5A, 5B are substantially annular and provided with respective fastening members 6 shaped so as to couple to the support 4, and more precisely to the collar portion 8, so as to be mutually interchangeable on the support 4.
  • the two adapter elements 5A, 5B (or all the adapter elements, if more than two) can selectively be fastened to the support 4 by means of the fastening members 6.
  • the adapter elements 5A, 5B consist of respective monolithic pieces, for example made of polymeric material.
  • the adapter elements 5A, 5B comprise respective substantially tubular drain portions 40A, 40B and respective radially outer coupling flanges 41A, 41B, located at respective axial ends of the respective drain portions 40A, 40B.
  • the drain portions 40A, 40B of the two adapter elements 5A, 5B are different from one another, being specifically configured for insertion in respective seats of different flush tanks.
  • the adapter elements 5A, 5B are provided with respective drain portions 40A, 40B, which are different from one another in shape and/or size and/or by being provided with different coupling members 42A, 42B for the coupling to the flush tank.
  • drain portions 40A, 40B can be different from one another.
  • the drain portion 40A of the adapter element 5A is shaped so as to engage a seat of a "one-piece” ceramic flush tank ( Figure 2 , right side), and the drain portion 40B of the adapter element 5B is shaped so as to engage a seat of a "two-piece” ceramic flush tank ( Figure 2 , left side).
  • the drain portion 40A comprises a substantially cylindrical side wall 43 having a pair of diametrically opposite axial projections 44, which project downwards from a lower edge of the side wall 43 and are tapered towards the bottom (in particular having a side substantially parallel to the axis A and a side inclined with respect to the axis A).
  • the drain portion 40A is also provided with a pair of grooves 45 placed adjacent to respective projections 44 on an outer side surface of the side wall 43 and parallel to the axis A; and a pair of holes 46 intended to receive, in use, screws or the like, and for example formed on respective radial projections 47, which radially project inside the drain portion 40A from the side wall 43 and are substantially radially aligned with respective grooves 45 and define, as a whole, the coupling members 42A.
  • the drain portion 40B ( Figure 6 ), instead, has coupling members 42B defined by an externally threaded sleeve 48 axially projecting from the respective coupling flange 41B.
  • the coupling flanges 41A, 41B of the adapter elements 5A, 5B are similar or substantially identical to each other and equipped with respective fastening members 6, which can be the same or different, but anyway shaped so as to couple to the support 4, and in particular to the flange 23 of the support 4, engaging respective fastening seats 27.
  • each adapter element 5A, 5B comprise a plurality of teeth 51, which project from a radially outer peripheral rim 52 of the respective coupling flange 41A, 41B and are angularly spaced apart from one another about the axis A.
  • the teeth 51 are in numbers and positions corresponding to the fastening seats 27 to be engaged thereby; in the non-limiting example shown, therefore, there are two diametrically opposite teeth 51 on the rim 52.
  • Each tooth 51 in elevation, is substantially hook-shaped (or has an inverted L shape), in particular comprising an axial stem 53 projecting axially upward from the rim 52, and a radial head 54 projecting radially inwards from the stem 53 and substantially perpendicular to the stem 53.
  • each tooth 51 has a lateral bevel 55, formed on one side of the tooth 51, and precisely of its head 54, and shaped to cooperate, in use, with the projection 32 of a corresponding fastening seat 27 to define a click-on connection 56 between the tooth 51 (i.e. the fastening member 6) and the fastening seat 27 (therefore between the adapter element 5A, 5B and the support 4).
  • the teeth 51, and precisely their heads 54, are axially insertable through respective access cavities 31 of the fastening seats 27.
  • Each head 54 is shaped so as to be housed in a fastening seat 27, between the projection 32 and the shoulder 33.
  • the teeth 51 are shaped so as to couple to the flange 23 of the support 4, and precisely to respective edge portions 29 in the fastening seats 27, between the respective heads 54 and an abutment surface 57 of the adapter element 5A, 5B.
  • the abutment surface 57 is formed on raised elements 58 axially projecting from the coupling flange 41A, 41B and, for example, facing respective heads 54.
  • the coupling flanges 41A, 41B are provided with respective centering collars 60 axially projecting from the respective coupling flanges 41A, 41B about the axis A on the opposite side of the respective drain portions 40A, 40B.
  • Each collar 60 is shaped so as to receive the collar 34 of the support 4 and cooperate with the sealing ring 36, which radially contacts an inner side surface 61 of the collar 60.
  • each collar 60 may also be shaped so as to be inserted inside the collar 34, again with the sealing ring 36 radially interposed between the collar 60 and the collar 34.
  • the adaptation kit 1 is selectively mounted on a flush tank 3A, 3B, the respective adapter element 5A, 5B being selected according to the flush tank ( Figure 2 ).
  • the selected adapter element 5A, 5B is mounted on the support 4 by means of an axial movement along the axis A and a subsequent rotation about the axis A of the adapter element 5A, 5B with respect to the support 4.
  • the teeth 51 are brought into the access cavities 31 and simultaneously the centering collar 60 is placed around the collar 34 of the support 4.
  • Each adapter element 5A, 5B is thus configured to selectively assume, with respect to the support 4:
  • the selected adapter element 5A, 5B is constrained to the support 4 crosswise to the axis A by the collar 34 inserted in the centering collar 60.
