Description

Background of the invention

The invention relates to an adjusting device for a water dispensing unit, in particular a manually operable device for opening, closing and adjusting the water flow in dispensing units which are provided in showers, wash basins for kitchens or bathrooms, etc.

State of the art

Devices for dispensing and shutting off water in a shower or a wash basin or a sink for kitchens or bathrooms are known.

Such devices are attached to a panel or to a wall of the dispensing unit and are designed so that they can be operated by the hand of a user.

One embodiment of these devices provides for the use of a control unit and a solenoid valve which, by electronic actuation, closes and opens the water flow to be supplied. Although very easy to use and aesthetically pleasing, their structural complexity makes such devices quite bulky and also expensive; such devices are also difficult to assemble, also because of the presence of electrical lines that must be connected.

Another embodiment of a device, in a manual version, provides for the presence of a large ceramic screw which is rotatable on a shaft in order to interrupt the flow of water.

The rotatable shaft can be rotated with the aid of a button that is located on the plate and can be operated by pressing it with the finger.

This last-mentioned device has the disadvantage that the user has to exert a high pressure on the button, which is greater, the higher the water pressure in the distribution circuit.

In order to reduce the effort required by the user, there are some solutions which provide for the use of reduction gears which are suitable for reducing the pressure to be exerted on the aforementioned button; however, such solutions are associated with an increase in the structural complexity and size of the adjustment device.

In order to overcome the aforementioned limitations, the present applicant developed a manual opening and closing system which is the subject of the patent EP2865928 and which has proven to be extremely effective, powerful and easy to manufacture.

This system has a button that can be manually switched to two different positions by lightly pressing with your finger to open and close the water flow and which can be further rotated to adjust the flow rate of the water exiting.

Although the EP2865928 disclosed device has proven to be a great improvement and is able to successfully solve the problems of the aforementioned prior art systems, there is still a great deal of room for improvement in current water adjustment devices.

Objects of the invention

An object of the invention is to improve current water adjustment devices.

Another object of the invention is to provide an adjustment device which is designed to improve the actuation of the locking means; in particular, the invention aims to provide a solution which makes it possible to further facilitate the operations of opening, closing and adjusting the flow of water for a user.

Another object of the invention is to provide a solution which makes it possible to simplify the construction of the setting device and at the same time to improve the operating behavior.

Yet another object of the invention is to provide a solution which makes it possible to reduce the size of the device and the space required for its mounting on a shower screen or other similar wall of a delivery unit, whereby advantages in terms of its appearance can also be achieved , especially in terms of the possibility of obtaining a mounting configuration that is perfectly flush with the wall or panel surface mentioned above.

These and other objects are achieved by a system as defined in the accompanying claims.

Brief description of the invention

According to the invention an adjusting device is provided according to the accompanying claims.

The present adjustment device is particularly advantageous in operation due to its special design, more precisely due to the manual control element, the control elements and the cam means, in particular during the actuation and adjustment of the closure means.

In addition, the particular structural design of the control elements and the control member brings about an advantageous structural simplification.

The adjustment device according to the invention is easy to manufacture and is particularly suitable for use in showers, sinks and other water-carrying components.

wherein the second actuator 5 with the closure means 3 via cam means 7th cooperates to the opening position A of the closure means 3 to change.

Further versions of the adjustment device 1 which can be designed with an actuation according to more than one variant, such as, for example, the provision of a magnetic or mechanical actuation arrangement for the closure means, are disclosed below.

With reference to the 1 until 11th is now a first embodiment of the adjustment device 1 described, which is provided by way of example and not limitation with a magnetic actuation. In short, in this embodiment is a magnetic transfer unit 21 arranged, which is adapted to the movement of the first actuating element 4th by means of a magnetic force on the closure means 3 transfers, between the closure means 3 and the first actuator 4th .

To this end, the transmission arrangement comprises 21 Magnetic means 30th that have a metallic or ferromagnetic part 31 of the closure means 3 cooperate.

More precisely, the closure means comprises 3 a pen 41 , on which the aforementioned metallic or ferromagnetic part 31 which is intended to work with the magnetic means 30th cooperate to obtain from them the magnetic force necessary to obtain an axial displacement along the axis X, as will be explained again below.

The valve body 2 is through a first body section 2a , a second body section 2 B and a third body portion 2c Are defined.

The first body section 2a and the second body portion 2 B are coupled with each other.

Inside the first body section 2a and the second body portion 2 B are at least a part of the first actuating element 4th and the second actuating element 5 as well as the closure means 3 housed.

The second body section 2 B is shaped so that it has a housing chamber inside 24 limited that towards the end that is from the control 6th is taken, protrudes, is closed at the top and the closure means 3 , especially the pen 41 , records.

Inside the housing chamber 24 there is a spring 26th who have favourited the pen 41 pushes outwards, specifically in the direction of a disk-membrane arrangement G, which will be explained later.

In the third part of the body 2c there are inlet I and outlet U for water.

The third section 2c the valve body is shaped so that it acts as a diffuser element for the flow of exiting water.

The third body section 2c is with the second body section 2 B coupled in such a way that they jointly delimit a chamber in which a disk-membrane arrangement G is accommodated.

In short, the disk-membrane arrangement G comprises a disk with an elastically deformable membrane and a rigid disk on which the membrane is received.
The disc is between the third section 2c and the second section 2 B of the valve body and serves as a sealing washer in between.

The disk-membrane arrangement G has a water inlet opening 39 and a water outlet port 40 on.

The disk-membrane assembly G enables or blocks, depending on the position reached, the flow of water through a water passage section 50 exit.

An intermediate position of the disk-membrane assembly G causes a reduction in the size of the aforementioned section of the water flow 50 and thus a division of the emitted water flow.

The water enters through the inlet opening 39 in a receiving chamber 23 one that is between an upper transverse wall of the second part 2 B of the valve body and the disc-diaphragm assembly G is limited.

Water coming from the distribution network and into the receiving chamber 23 occurs, can be under a water pressure between 0.1 and 10 bar, a pressure to which the disk of the aforementioned assembly G is exposed.

The closure means 3 include one with the pen 41 coupled disc end 42 , which is designed to have the aforementioned outlet opening 40 closes when a closed position C is reached. The closed position C is in 6th easy to see where you can see that the disk-membrane arrangement G the water passage section 50 locks.

Through the inlet port 39 presses that in the chamber 23 Any water present down the disk, as a result of which the elastic membrane of the disk-membrane arrangement G is partially deformed.

The end of the disc 42 closes the outlet opening 40 so that the water pressure (in from top to bottom), which the membrane and the disc or the rigid disc-shaped element against the water passage section 50 presses, equal to the pressure of the in the inlet port 39 incoming water is. The different areas of the surfaces that are subjected to the pressure on the upper side and the lower side of the disc-shaped element determine the state of the disc-shaped element and the membrane which is against the flow-through water passage section 50 to press.

It goes without saying that there is a shift in the shutter 3 by a few millimeters is sufficient to trigger a displacement of the disk G in order to close and open the water flow through the lower passage.

Thanks to the magnetic actuation, a light touch of the hand control is sufficient 6th with a finger to move the shutter and magnet into the release position of the disc to open or close the flow.

The greater or lesser distance to the end 42 from the outlet port 40 , by acting on the second actuating element 5 is set (as will be better understood in the following description), determines a desired change and setting of the flow rate of the through the flow-through water passage section 50 escaping water.

A possible partially open position P is in the 7th and 10 shown. The second actuator 5 is essentially cylindrical and as a rotatable ring element 5 educated.

Such a rotatable ring element is advantageous 5 not screwed, but only in an upper seat of the valve body 2 recorded and maintains its position along the longitudinal axis X, ie the portion along the axis X of the second actuating element 5 (rotatable ring element 5 ) does not change during the rotation of the second operating element 5 .

This makes coupling with the manual control easier 6th and also leads to a simpler and easier assembly of the arrangement. To be precise, the dimensions are significantly reduced, especially in the transverse direction; and thanks to the lack of threaded areas for the second actuator 5 is a smaller wall thickness for both the second actuating element 5 as well as that of the receiving valve body 2 necessary.

The first actuator 4th is by a first actuator 4 ' and a second actuator 4 " formed, which are intended to come into contact with each other.

Both the first actuator 4 ' as well as the second actuating element 4 " have an elongated shape, extend along the axis X and are defined by a narrow upper part, which is substantially cylindrical and has a small diameter, and an enlarged lower part with a larger diameter, which is circular and transverse to the aforementioned longitudinal axis X. extends.

The second actuator 4 " is in the housing chamber 24 of the second section 2 B attached to the valve body and can move relative to it.

In other words, the housing chamber 24 penetrates the enlarged lower part of the second operating element 4 " one in which a return spring 27 is provided and arranged to the first actuating element 4th from the second section 2 B to push away the valve body. In other words, the return spring 27 presses the first actuator 4th up (i.e. towards the control 6th ), as shown in the attached figures.

The first actuator 4th is structurally designed so that the enlarged lower part of the first element 4 ' the narrow, substantially cylindrical, upper part of the second actuating element 4 " can accommodate.

In other words, the second actuating element 4 " is partially and coaxially in the first actuating element in the assembled state 4 ' fitted.

The second actuator 4 " is therefore partially in the first actuator 4 ' fitted, and the two elements are through a hole-hook coupling 35 ( 6th ) that allows relative rotation but prevents their separation.

The magnetic means 30th are in the enlarged lower part of the second operating member 4 " recorded.

The magnetic means 30th comprise, according to one possible, non-limiting embodiment, a magnet 30th having a toroidal or annular shape located inside the enlarged lower part of the second operating member 4 " is attached.

The magnet 30th extends circumferentially around and outside the housing chamber 24 , in which the metallic part 31 of the closure means 3 is included.

The axial movement of the first actuator 4th and with it the movement of the magnet connected to it 30th leads to a corresponding movement of the metallic part due to the exerted magnetic attraction force 31 and with it the pen 41 of the closure means 3 .

The metallic part 31 is not in contact with the magnet 30th , but is from this through the intermediate wall, which the housing chamber 24 limited, separated.

The elastic force of the spring 26th that is squeezed makes it easier to move the pen 41 from the housing chamber 24 out and in the direction of the disc-membrane arrangement G.

The one by the magnet 30th on the metallic part 31 exerted magnetic pulling force is chosen so that it has the effect of the pressure of the liquid inside the receiving chamber 23 in one step of ejecting the pen 41 from the housing chamber 24 overcomes and the elastic force of the spring 26th in a step of reinserting the pin 41 into the housing chamber 24 overcomes to reach the position of the full opening A (clearly visible in the 2 until 6th ).

The first actuator 4th is by a very light pressure exerted by the user on the outermost tip, sliding - along the axis X - into the valve body 2 emotional. The displacement of the magnet 30th that goes completely through the pen 41 is separated, determines by magnetic action the displacement of the latter in an extremely simple, precise and quiet way.

The first actuator 4 ' and the second actuator 4 " engage each other in the respective sawtooth-shaped sections 20th obtained at the respective enlarged sub-parts mentioned above.

The sawtooth-shaped sections 20th form interruption zones 32 into corresponding axial guide projections 33 intervene within the first section 2a of the valve body are formed.

When the first actuator 4th is moved axially, slide the interruption zones 32 along the axial guide projections 33 that act as rails that are suitable to prevent rotation about the longitudinal axis X.

The second actuating element moves under pressure from the user 4 " only axially for a certain distance, guided by the axial guide projections 33 that prevent it from rotating, but then the interruption zones become detached 32 of the second actuating element 4 " from the axial guide projections 33 .

Now the second actuator 4 " that can rotate freely due to the interaction between the inclined surfaces attached to the sawtooth-shaped sections 20th of the two controls 4 ' , 4 " are provided for a rotation with an angular division with respect to the first actuating element 4 ' forced.

The second actuator 4 " is initially arranged in a position with each rotation by an angular division, which is farther from the receiving chamber 23 away (opening position A), and then in a position closer to the receiving chamber 23 (closed position C), and so on, alternately.

The sawtooth-shaped sections 20th are geometrically designed so that they interact with each other to create a snap motion for the first actuating element 4th while it changes from opening position A to closing position C and vice versa.

The on the first actuator 4th The compressive forces exerted determine the successive positioning of the second actuating element 4 " in the open position A and in the closed position C, i.e. switching over the locking means 3 from the open position A to the closed position C and vice versa, alternately.

Reaching the most distant position or the position closest to the disk-membrane arrangement G is made possible by the fact that in the first case the second actuating element 4 " with the interruption zones 32 attached to the axial protrusions 33 are arranged and engage in this, is oriented at an angle, so that the second actuating element 4 " toward the top of the adjuster 1 can slide until it hits the first actuator 4 ' caused against cam means 7th to bump that on the second actuator 5 are attached.

The cam means 7th define the end position of the opening (ie they define the opening position A) for the first actuating element 4th and consequently for the locking means 3 which are taken axially by the latter.

In the second case (closest position to the disk-membrane assembly G) is the second actuating element 4 " angled, with the interruption zones 32 in relation to the axial guide projections 33 are offset and do not intervene in this: The sawtooth-shaped sections 20th butt against the axial projections 33 and thus hold the second actuating element 4 " tight and prevent it from going to the top of the device 1 returns. In this way, the closed position C is maintained.

The first actuator 4 ' is in relation to the ring element 5 axially movable when subjected to pressure exerted by the user.

The second actuator 5 is partially inside the first valve body part 2a housed.

The second actuator 5 consists of a first inner part 5 ' , which is in a seat area of the first valve body part 2a is housed, and from a second part 5 " from the first valve body part 2a protrudes through an existing upper opening in this.

On the first inner part 5 ' are the cam means 7th , through which it is possible to adjust the end position of the opening A of the closure means 3 as will be explained in detail later.

The second part 5 " is instead intended to be used with manual control 6th to come into engagement in order to be rotated and the adjustment of the open end position of the closure means 3 to enable and a desired partially open position P ( 10 ) or to reach an intermediate position.

The second actuator 5 has a hollow shape that is substantially cylindrical-tubular and defines an elongated through cavity that is open at both ends.

The second actuator 5 contains part of the first actuating element 4th , namely the first actuator 4 ' , or it is penetrated by this axially.

The first actuator 4 ' protrudes over the outermost end of the second actuating element 5 addition, so it's with manual control 6th is engaged.

The cam means 7th and their mode of operation for changing the stroke end position, ie the open position A of the closure means 3 , are described in more detail below.

The cam means consist of a shaped edge 7th at one end E of the second actuating element 5 , especially at the bottom of the first part 5 ' , which is intended to be in the valve body 2 to be included.

According to other embodiments not shown, however, it is possible to have cam means in other areas of the second actuating element 5 such as inside and near the top of the second actuator 5 that is, closer to the area created by the presence of the manual control intended for the user 6th is affected.

On the first actuator 4th , in particular on the first actuating element 4 ' , is a driver relief 19th which is formed to match the profile of the formed edge 7th is in contact and follows this.

The profile of the formed edge 7th is geometrically designed so that the rotation of the second actuating element 5 a shift in the aforementioned driver relief 19th and consequently an axial displacement of the first actuating element 4 ' along the longitudinal axis X causes the opening position A of the closure means 3 to regulate.

In particular is the profile of the formed edge 7th or the cam profile 7th designed so that by turning the second actuator 5 clockwise the opening end position of the closure means 3 closer to the water outlet opening 40 the disc-membrane arrangement moves closer to the flow rate of the through a water passage section 50 to reduce escaping water, and vice versa moves by turning the second actuating element 5 counterclockwise the opening end position of the closure means 3 from the water outlet 40 away to the flow rate of the flow through the water passage section 50 to increase exiting water flow.

The cam profile 7th can be geometrically designed to provide more or less inclined paths depending on the specific needs / preferences or operational requirements that must be met.

The cam profile can have a progressive or step-shaped course in order to achieve an adjustment of the flow rate, which can vary continuously or also discretely.

Other designs can also be envisaged, but functionally equivalent to the cam means 7th are.

The rotation of the second actuator 5 , for the sake of simplicity as a ring element 5 can be referred to is by a protrusion 37 limited, which is attached to this element and in an eyelet 38 on the first part 2a of the valve body engages. The eyelet 38 extends around the X-axis in the circumferential direction for a certain angular range.

The ends of the angled area of the eyelet 38 each limit the outer angular positions that the rotatable ring element 5 can occupy, and thus determine the maximum and minimum setting positions of the flow rate of the exiting water flow.

According to a further possible embodiment, which is not shown, instead of the cam means 7th other means for converting rotation of the second actuator 5 into a displacement of the closure means 3 be provided to regulate the end of the stroke in the opening position A - between the second actuating element 5 and the closure means 3 and / or the first actuating element 4 ' .

The manual control ( 6th ; 6A ; 6B , 6C ) will now be described in more detail.

In particular with reference to 3 becomes a first embodiment of the aforementioned manual control 6th , 6A described.

According to this first implementation, the control is manual 6th through a single control 6A which is made from a single piece.

Such a single element is suitable for absorbing a pressure effect exerted by a user along the longitudinal axis X (for opening and closing the water dispenser) and a rotary effect around the same longitudinal axis X (for regulating the flow rate of the water to be dispensed).

The manual control includes a connector section 8A which is shaped to connect to the first actuator 4th allows, and an engaging portion 9A which is shaped to interact with the second actuator 5 comes into engagement.

The coupling section comprises, in particular, a through hole 8A that is shaped to be a fastener 15th such as B. a screw can receive, which is in one on the first actuating element 4th formed mounting cavity 16 can intervene.

The single control 6A is dome-shaped and consists of a disc-shaped part 10A , on which the above-mentioned connection section 8A located, and from a tubular part 11A that from a surface 12th of the disc-shaped part 10A sticks out.

The engaging portion 9A is on the tubular part 11A educated.

The aforementioned engaging portion includes a shaped surface 9A which is designed to fit into a corresponding conjugate shaped surface 17th engages on the second actuating element 5 is trained.

The shaped surface 9A includes raised and / or recessed elements that are adapted to mate with corresponding recessed and / or raised elements of the shaped conjugate surface 17th of the second actuating element 5 (Ring element 5 ) come into engagement.

According to one possible, non-limiting embodiment, the raised and / or recessed elements comprise ribs and / or grooves that extend parallel to the longitudinal axis X.

The manual control 6th comprises an aesthetic cover element 13A which has a button shape adapted to receive a touch by the user.

The end cover element 13A is with hook elements 18A provided that are shaped so that they come with holding zones 14A connect that on the control 6th , 6A available.

The adjustment device 1 is with a mounting sleeve 25th with which it can be attached to a sink or shower panel.

The adjustment device 1 is designed so that it can be mounted concealed, the only cover element 13A is visible and facing the user when in the closed position C.

In particular, a mounting arrangement can be selected that is flush with the surface S of the shower panel or the vanity top.

As in 6th shown schematically, the cover element 13A in the closed position C of the adjustment device 1 a completely flat upper side T which is flush with the surface S of the shower panel or the sink tabletop.

When the user exerts an opening pressure, the cover element protrudes 13A outwardly beyond the surface S, so that the user the cover element 13A , ie the control 6A , can grab and turn.

The control 6A , in particular the cover element 13A , can be small, it can have an outer surface that has an area almost equal to or greater than a finger pressure area to have a minimal and elegant aesthetic appearance.

On the top of the cover element 13A If it is so large that it is larger than a finger of the user, a recessed area or a recess in an off-center area can also be provided in order to allow the cover element to rotate 13A to enable even with one finger.

A clockwise or counterclockwise rotation of the control 6A in relation to the valve body 2 can take place while the water is being dispensed, which enables the dispensed throughput to be set in real time, or in the closed state (no water dispensing); in this case it is possible to check the delivered throughput before opening the adjustment device 1 to adjust.

The adjusting device thus formed 1 In addition to its high level of comfort, it is also characterized by a very pleasant aesthetic.

With reference to the 4th is now a second execution of the aforementioned manual control 6th , 6B , 6C described, which has many features in common with the first embodiment just described and will therefore not be described again.
According to this embodiment, the manual control element is through a first control element 6B and a second control 6C that are different and separate from each other.
