Description

Field of the invention

[0001] The present invention relates to a drain fitting for sinks according to the preamble of independent claim 1.

[0002] The waste fitting in question can be advantageously used to allow water to drain from a sink (or basin) into a waste pipe and can be used in both residential and professional environments.

[0003] The drain fitting can preferably be used for kitchen, bathroom or laundry room sinks, but is of course also suitable for general sinks regardless of their intended use.

[0004] Therefore, the present invention is to be located in the industrial sector of the production of hydraulic equipment and accessories, in particular drain fittings. State of the art

[0005] Drain fittings are available on the market that allow water to flow from a sink into a drainpipe. These drain fittings consist of a drain body attached to the bottom of the sink and hydraulically connected to the drainpipe. A basket is located inside the sink at the drain opening and connected to the drain body by means of a sleeve with a gasket inserted between them to ensure the attachment of the drain body to the sink and the drainage of water without leaks.

[0006] The drain fittings also include a component with a seal positioned under the basket and with an elongated stem that is movable inside the socket to allow vertical movement of the basket between a raised drainage position and a lowered position to prevent water from flowing into the drain pipe.

[0007] These conventional drain fittings allow the user to manually move the basket as needed to allow or prevent water from flowing from the sink into the drainpipe.

[0008] However, these solutions of drain fittings with manual baskets have proven to be impractical in use.

[0009] Therefore, over time, technical solutions have been developed that allow the basket to be moved automatically using a (mechanical or electrical) actuator positioned on the edge of the sink.

[0010] These solutions are known on the market as automatic wastes. Specifically, automatic wastes comprise a mechanical or electrical actuator connected to a metal cable, one end of which is connected to an operating mechanism. Specifically, the operating mechanism is connected to the basket's elongated stem to move it between the raised and lowered positions, following the cable's movement by means of the actuator. To ensure the proper functioning of this automatic device, the cable must be correctly tensioned and not loosened. For this purpose, conventional wastes provide for the cable to pass through a sliding seat arranged on a connecting element, which is fixed to the body of the waste by means of a plate.In detail, the plate is screwed to the cup body with the help of a screw and carries the mounted connection element in which the cable is slidably accommodated.

[0011] The drain fittings of the known type have proven in practice to be not free of problems.

[0012] The biggest disadvantage of these drain fittings is the fact that they are impractical and difficult to install and remove.

[0013] Installation and removal require inserting the cable into the connector, mounting the connector on the mounting plate, and attaching the plate to the bowl body by inserting and tightening the fixing screw. These operations are not only time-consuming but also inconvenient and complicated to perform. In some cases, the sink is installed inside cabinetry that presents poor and limited access to the drain assembly and, in particular, to the area where the automatic device's plate is attached. This makes the use of tools for installing and removing the plate even more inconvenient and difficult.

[0014] A further disadvantage arises from the fact that these operations are not easy for the end user to perform and require specialized personnel.

[0015] Therefore, conventional drain fittings of the type described above are difficult to disassemble to replace the automatic device, for example in the event of malfunction or breakage of the actuator, cable or other installed electromechanical components. Disclosure of the invention

[0016] In this situation, the problem underlying the present invention is therefore to eliminate the problems of the above-mentioned known technology by providing a drain fitting for a sink which can be installed and removed effortlessly and easily even by non-qualified personnel.

[0017] A further object of the present invention is to provide a drain fitting having a reduced number of components for its manufacture.

[0018] Another object of the present invention is to provide a drain fitting that is inexpensive to manufacture.

[0019] Finally, it is an object of the present invention to provide a drain fitting that is stable and durable during its use. Short description of the figures

[0020] The technical characteristics of the invention, in accordance with the objects set out above, are clearly evident from the content of the claims below and the advantages thereof will become even clearer from the detailed description given below with reference to the accompanying drawings, which represent a mere and non-limiting example thereof, in which: - Fig. 1A shows a perspective view of the drain fitting forming the subject of the present invention according to a first embodiment; - Fig. 1B another view of the drain fitting from Fig. 1A shows one basket removed; - Fig. 2 a side view of the drain fitting Fig. 1A shows; - Fig. 3 a side view of the drain fitting Fig. 2 shows; - Fig. 4 a single part of the drain fitting made of Fig. 1 shows a connecting sleeve and a cover element in the open position; - Fig. 5 another view of the individual part of the drain fitting from Fig. 4 with the connecting sleeve removed to better see the cover element; - Fig. 6 a top view of the drain fitting Fig. 1B shows ; - Fig. 7 a single part of the drain fitting made of Fig. 1A in relation to the cup; - Fig. Figure 8 shows a perspective view of the drain fitting subject of the present invention according to a second embodiment and with a cover element in an open position; - Fig. 9 the drain fitting Fig. 8 with the cover element in a closed position; Detailed description of an example of a preferred embodiment

[0021] With reference to the accompanying figures, a drain fitting for a sink according to the present invention has been designated in its entirety by 1.

[0022] The waste fitting 1 in question can be advantageously used in both domestic and professional environments to allow the drainage of liquids from a sink into a drainpipe.

[0023] According to the invention, the drain fitting 1 in question comprises a cup body 2, preferably made of plastic, which is provided with a guide bushing 20, which is provided internally with a central guide channel 20' extending along a main direction Y, and with a drain line 21 extending around the guide bushing 20. In particular, the guide channel 20' is hydraulically separated from the drain line 21.

[0024] As can be seen from the accompanying figures, the cup body 2 advantageously has an internal concavity. In particular, the cup body 2 extends between a widened inlet opening 22, which is intended to be arranged near a bottom of the sink, and an outlet opening 23, which is intended to be hydraulically connected to a water drainage pipe not shown in the accompanying figures. According to a Fig. In the first embodiment shown in Figure 1, the cup body 2 of the drain fitting 1 consists of two separate elements which are connected to each other, for example by screwing.

[0025] In particular, the cup body 2 advantageously comprises an upper element 201 intended to be arranged near a bottom of the sink and on which the aforementioned inlet opening 22 is arranged, and a lower element 202 arranged downwards along the main direction of extension Y relative to the upper element 201 to which it is attached, and on which the outlet opening 23 is arranged. Advantageously, the lower element is hydraulically connected at the outlet opening 23 to a fitting which hydraulically connects the drain line 21 to the drain pipe and which preferably extends horizontally, substantially orthogonally with respect to the main direction of extension Y.

[0026] This type of connection, known in technical jargon as a "body-supporting curve", allows the drain fitting 1 to be installed even in confined spaces and is therefore considered a space-saving solution compared to conventional solutions with drain fitting 1 and cup body 2 made from a single piece.

[0027] According to a Fig. 8 and Fig. In the second embodiment shown in Figure 9, the cup body 2 consists of one piece 203 and therefore runs with a single element between the inlet opening 22 and the outlet opening 23.

[0028] In this case, the outlet opening 23 is preferably substantially coaxial with the inlet opening 22 and therefore the drain pipe is suitable to be connected below the cup body 2 and not laterally as in the case of the first embodiment.

[0029] The drain line 21 advantageously runs in the circumferential direction around the main direction Y of the guide bush 20, preferably with a substantially V-shaped course.

[0030] The drain fitting 1 also comprises a basket 3. In particular, the basket 3 is intended to be arranged inside the sink at a drain opening of the latter, preferably adjacent to a support body positioned as a cover for the drain opening. The basket 3 is provided with a basket body 30 and an elongated shaft 31, which is slidably engaged in the guide channel 20 of the cup body 2 along the main direction of travel Y.

[0031] In particular, the elongated shaft 31 is suitable for engaging the drain opening of the sink and the guide channel 20' of the guide bushing 20.

[0032] Advantageously, the drain fitting 1 comprises a threaded bushing 100 which is hollow inside.

[0033] Specifically, the threaded bushing 100 is connected to the basket 3 and engages by screwing into the guide channel 20' (preferably threaded) of the bushing 20 in order to connect the basket 3 and the cup body 2 to each other, as shown in Fig. 3 recognizable.

[0034] The elongated shaft 31 of the basket 3 is movable along the guide channel 20' (and preferably inside the threaded bushing) along the direction Y between a raised position in which it allows the flow of water in the said drain line 21 and a lowered position in which it substantially prevents the flow of water in the drain line 21.

[0035] In particular, the basket 3 is provided with a stop surface directed towards the cup body 2, which is designed to close the drain opening of the sink when the basket 3 is in the lowered position, so as to substantially prevent the water from crossing the above-mentioned drain opening.

[0036] The drain fitting 1 also comprises actuating means 4 comprising a lever 40 pivotally connected to the cup body 2 and rotatable about a rotation axis R, and an actuating cable 41, preferably a metal cable such as a Bowden cable, extending between a first end 41' connected to the lever 40 and an opposite second end 41" suitable for connection to an actuator, which may be a mechanical or electrical actuator, actuated to move the actuating cable 41 along an actuating direction X substantially orthogonal to the rotation axis R and the direction of travel Y, in order to rotate the lever 40 about the rotation axis R and to control the movement of the basket 3 between the raised position and the lowered position.

[0037] In detail, the lever 40 is preferably rotatably mounted on the cup body 2 on its first side and connected to the actuating cable 41 on its second side opposite the first, as shown in Fig. 1 recognizable.

[0038] According to the concept underlying the present invention, the actuating means 4 of the drain fitting 1 comprise a support element 5 that is attached to the cup body 2. Advantageously, the support element 5 extends in a projecting, one-piece manner from the cup body 2 and preferably extends in a projecting manner from a side flank of the cup body 2.

[0039] In particular, the support element 5 according to the first embodiment extends laterally projecting from the lower element 202 of the cup body 2, while in the case of the second embodiment the support element 5 naturally extends projecting from the body in one piece 203 of the cup body 2.

[0040] The support element 5 is equipped with a housing seat 50 provided with a lateral insertion opening 51 and an internally hollow connecting sleeve 6 in which the actuating cable 41 is slidably accommodated and which is accommodated in the housing seat 50 of the support element 5.

[0041] Advantageously, the connecting sleeve 6 has an outer lateral surface 60 that is substantially cylindrical, even if it does not extend with a constant diameter, as described in more detail below, and the housing seat 50 of the support element 5 has an inner wall that is also, at least partially, substantially cylindrical, to allow the connecting sleeve 6 to rotate freely in the housing seat 50 and prevent twisting of the connecting sleeve 6 during the assembly phase. In particular, the connecting sleeve 6 advantageously extends between two opposite ends 6', 6", at which corresponding, interconnected, insertion openings 61 are provided, defining a receiving channel for the cable 41.

[0042] Advantageously, the connecting sleeve 6 is made entirely of polymer material. The connecting sleeve 6 can be inserted into the housing seat 50 via the lateral insertion opening 51 along an insertion direction Z substantially orthogonal to the actuation direction X and is held in the housing seat 50 by the support element 5 for movements parallel to the actuation direction X.

[0043] The actuating means 4 also comprise a cover element 7, preferably of the flap type, which is connected to the support element 5 and is movable between an opening position and a closing position in order to open / close the insertion opening 51 of the housing seat 50.

[0044] In this way, it is possible to hold the connecting sleeve 6 in a simple and effortless manner inside the housing seat 50 of the support element 5, from which it can be easily removed by simply opening the cover element 7.

[0045] Advantageously, the actuating cable 41 is detachably connected to the lever 40 at its first end 41', preferably by means of bayonet-type connecting means. In particular, the lever 40 is advantageously provided with a housing cavity accessible from one side of the lever 40 and oriented orthogonally to the actuating direction X. The actuating cable 41 is equipped at its first end 41' with a widened head, e.g., a ball head, which can be inserted into the housing cavity of the lever 40 by sliding it along the aforementioned direction orthogonal to the actuating direction X.

[0046] Advantageously, the housing cavity of the lever 40 and the widened head 41 are shaped so that they can only perform movements parallel to the actuation direction X.

[0047] In other words, the movement of the actuating cable 41 along the actuating direction X causes the lever 40 to rotate about the rotation axis R clockwise or counterclockwise, depending on whether the actuating cable 41 is pushed or pulled by the actuator.

[0048] Advantageously, the actuating means 4 comprise a connecting tube 42 which projects from the lever 40 and runs parallel to the axis of rotation and is preferably formed in one piece therewith.

[0049] In particular, the connecting tube 42 projects from the lever 40 from the first side of the latter and is preferably housed in a cylindrical receiving portion provided on the cup body 2, inside which the connecting tube 42 can rotate about the rotation axis R.

[0050] Advantageously, the actuating means 4 also comprise a thrust element 43 which projects radially from the connecting tube 42, preferably in one piece, and is arranged substantially symmetrically to the lever 40.

[0051] In particular, the pushing element 43 is rotatable about the rotation axis R and exerts pressure against the elongated shaft 31 of the basket 3 in order to move it along the direction Y following its own rotation about the rotation axis R.

[0052] Advantageously, the connecting sleeve 6 can be accommodated in the housing seat 50 of the support element 5, where it slides freely along the insertion direction Z.

[0053] Of course, the sleeve 6 can slide freely in the housing seat 50 along the insertion direction Z, in particular when the cover element 7 is open.

[0054] Specifically, the term "freely sliding" means that the connecting sleeve 6 essentially does not overlap the support element 5 when sliding along the insertion direction Z, except for possible minor obstructions due to dimensional tolerances. Likewise, it is understood that when removing the connecting sleeve 6 from the housing seat 50 of the support element 5, there is no mechanical obstruction or interference that would prevent the unhindered removal of the connecting sleeve 6 with the cover element 7 open.

[0055] In other words, the cover element 7 is advantageously the only element that holds the connecting sleeve 6 on the support element 5 for movements parallel to the insertion direction Z. Advantageously, the support element 5 is shaped such that it has an insertion opening 51 and a housing seat 50 with larger dimensions compared to the connecting sleeve 6.

[0056] In particular, the connecting sleeve 6 has an external dimension along a direction parallel to the main direction of extension Y that is smaller than the dimensions of the insertion opening 51 and the housing seat 50 along the same direction. Advantageously, one element below the connecting sleeve 6 and the support element 5 is provided with at least one groove extending circumferentially around the actuation direction X, and the other element below the connecting sleeve 6 and the support element 5 is provided with at least one engagement projection 9 extending radially relative to the actuation direction X and engaging in the groove 8 to secure the connecting sleeve 6 and the support element 5 for movement along the actuation direction X.

[0057] Preferably, the groove 8 and the engagement projection 9 are shaped so as to be interconnected for movement along the actuation direction X and thus prevent the relative movement between the connecting sleeve 6 and the support element 5, but allow the mutual rotation of these elements, in particular to enable the rotation of the connecting sleeve 6 about the actuation direction X and at the same time prevent its rotation during assembly of the device 1.

[0058] Accordingly, the engagement projection 9 and the groove 8 are arranged in contact with each other by means of corresponding engagement surfaces extending substantially circumferentially around the actuation direction X, to ensure the mutual sliding of these surfaces should the connecting sleeve 6 be rotated during its assembly. Preferably, according to the embodiments illustrated in the accompanying figures, the groove 8 is provided on the connecting sleeve 6 and the engagement projection 9 is arranged on the support element 5.

[0059] In particular, the connecting sleeve 6 has an outer side surface 60 and the groove 8 extends radially and recessed downwards from the outer side surface 60 of the connecting sleeve 6.

[0060] Advantageously, the engagement projection 9 extends in the circumferential direction starting from an inner surface of the support element 5 towards the interior of the housing seat 50. In particular, the engagement projection 9 extends in a circular arc on the support element 5, which is interrupted by the insertion opening 51.

[0061] Specifically, the groove 8 on the connecting sleeve 6 defines a narrowed portion of the connecting sleeve 6, the latter having a reduced first diameter which is smaller compared to a first diameter of the connecting sleeve 6.

[0062] Furthermore, the engagement projection 9 preferably defines a narrowed passage portion inside the housing seat 50, at which the support member 5 has a reduced second diameter that is smaller compared to a second diameter of the support member 5.

[0063] In detail, the second reduced inner diameter is understood to be the distance between two diametrically opposite points of the engagement projection 9.

[0064] Preferably, the second reduced inner diameter defined by the engagement projection 9 is larger than the first reduced inner diameter defined by the groove 8.

[0065] Advantageously, the connecting sleeve 6 is provided with two grooves 8 which extend circumferentially recessed from the outer side surface 60 of the connecting sleeve 6 and are spaced apart from one another along the actuating direction X, and preferably the support element 5 is provided with two engagement projections 9, each of which engages in a corresponding groove 8 of the connecting sleeve 6.

[0066] Advantageously, the support element 5 extends between a first end piece 5' directed toward the first end 41' of the cable 41 and an end piece 5'' directed toward the second end 41'' of the cable 41. Advantageously, the engagement element 5 extends along the actuation direction X between a rear opening 53 directed toward the second end 41' of the actuation cable 41 and in particular toward the second end piece 5'', and an opposite front opening 54 directed toward the first end 41' of the actuation cable 41 and in particular toward the first end piece 5'.

[0067] In particular, the support element 5 comprises two opposite end walls 55, 56 (front and rear) which are arranged at the respective end pieces 5', 5" of the support element 5 and on which the corresponding openings 54, 53 are arranged.

[0068] Preferably, the rear end wall 56 defines one of the above-mentioned engagement projections 9 and therefore engages in one of the two grooves 8 of the connecting sleeve 6.

[0069] In particular, the connecting sleeve 6 comprises, as shown in Fig. 4, a first groove 8, which is accommodated in the housing volume 50, and a second groove 8, which is arranged upstream in the actuation direction X and is positioned at the rear opening 53 of the support element 5, preferably substantially as a closure of the latter.

[0070] Preferably, the aforementioned grooves 8 of the connecting sleeve 6 do not have the same diameter. In particular, the connecting sleeve 6 comprises a first widened portion 62 which laterally delimits the first groove 8 and in turn defines the second groove 8. Preferably, the first widened portion 62 is housed with clearance in the housing seat 50 and is inserted between the two engagement projections 9. In particular, the first widened portion 62 extends between two opposite surfaces intended to overlap with the lateral flanks of the respective engagement projections 9 in order to prevent the sliding of the connecting sleeve 6 in the housing seat 50 of the support element 5 along the actuation direction X, but not the rotation of the cable 41 about the actuation direction X.

[0071] Preferably, the first widened portion 62 has a width, measured along the above-mentioned actuation direction X, which substantially corresponds to the distance between the mutually facing side flanks of the two engagement projections 9.

[0072] Advantageously, the connecting sleeve 6 comprises a second widened portion 63 extending from the first groove 8 toward the first end 41' of the actuating cable 41, preferably until it protrudes from the front opening 54 of the support element 5. Alternatively, it is possible to provide for the second widened portion 63 to extend to the front opening 54 and preferably to be positioned so as to abut the end wall 55 of the support element 5.

[0073] Advantageously, when the cover element 7 is in the closed position, the housing seat 50 is accessible from the outside exclusively via the front opening 54 and the rear opening 53. In this way, the housing seat 50 is closed and protected against the ingress of dirt.

[0074] Advantageously, the support element 5 is provided with at least one engagement slot 52 and the cover element 7 is equipped with at least one engagement flap 71 which can engage in the engagement slot 52 of the support element 5 in order to fix the cover element 7 to the support element 5 in the closed position.

[0075] Advantageously, according to a preferred embodiment, the cover element 7 comprises a substantially plate-shaped flap 70 which is arranged coplanar with the insertion opening 51 and closes the latter.

[0076] Otherwise, according to a variant embodiment of the cover element 7, it comprises a cylindrical body which essentially forms a counter-profile to the outer side surface 60 of the connecting sleeve 6 and is positioned to at least partially enclose the latter when it is arranged in the closed position.

[0077] Advantageously, the engagement flap 71 projects from the flap 70, preferably parallel to the axis of rotation R.

[0078] Advantageously, the entire cover element 7 is made from one piece, preferably from polymer material.

[0079] The engagement flap 71 may have an elongated shape parallel to the actuation direction X or a pin shape which is therefore extended orthogonally to the same actuation direction X.

[0080] In addition, the cover element 7 may comprise a single engagement flap 71, as in Fig. can be seen, or several engagement flaps 71, which are preferably arranged on opposite sides of the flap 70

[0081] Preferably, the engagement flap 71 of the cover element 7 is designed such that it engages in the engagement slot 52 of the support element 5.

[0082] For example, the engagement flap 71 is advantageously provided with a substantially wedge-shaped portion designed to deform elastically and engage in the engagement slot 52 of the support element 5.

[0083] In particular, the support element 5 is advantageously provided with an engagement step 58 which extends towards the center of the insertion opening 51 and is designed to hold the cover element 7 in the closed position, in particular by cooperating with the engagement flap 71 of the latter.

[0084] More specifically, when the cover element 7 is brought into the closed position, the engagement flap 71 overlaps with the engagement step 58 and at least one of these two elements deforms elastically to allow the passage of the engagement flap 71 and thus the closing of the cover element 7 so that the latter engages on the support element 5.

[0085] Advantageously, the support element 5 is provided with an engagement portion 57, on which the engagement slot 52 and preferably also the engagement step 58 are mounted and which preferably extends in a projecting manner away from the housing volume 50. Advantageously, the engagement portion 57 allows the release of the engagement flap 71 of the cover element 7 by acting on an end portion of the engagement portion 57 and bending it slightly in order to be able to pull the engagement flap 71 out of the engagement slot 52.

[0086] In other words, during the above-mentioned operative phase, it is the engagement portion 57 that elastically deforms to allow the passage of the engagement flap 71 and thus the closing of the cover element 7.

[0087] Of course, it is also possible that the cover element 7 does not comprise an engagement flap 71 and engages elastically with an edge of the body with flap 70 in the engagement step 58, as in the Fig. 9 and Fig. 10 recognizable.

[0088] Advantageously, the cover element 7 is hinged to the support element 5 about a hinge axis parallel to the actuation direction X and is rotatable about this hinge axis between the opening and the closing position.

[0089] Advantageously, the engagement portion 57 extends from a side of the support element 5 which is opposite to the side to which the cover element 7 is hinged, as in Fig. can be seen.

[0090] Preferably, the cover element 7 is designed in one piece with the support element 5 and is preferably hinged to the support element 5 by means of virtual hinges defined by areas of reduced thickness inserted between the cover element 7 and the support element 5 in order to reduce to a minimum the components required for the manufacture and assembly of the drain fitting 1.

[0091] Of course, it is also possible to provide real hinge elements between the cover element 7 and the support element 5.

[0092] The invention thus conceived therefore solves the set tasks.
