Description

The invention relates to a hangriff the plumbing batteries, provided with ball valve, which can secure the predosing of the water flow, according to the actual needs of the consumer, to rationalize water consumption.

One knows that when using the water battery in the bathroom or in the kitchen, one does not always need the maximum water jet. Securing a smaller or moderate jet of water is accomplished by adjusting the position of the handle, which often, either for convenience or because of the difficulty of being easily and quickly positioned, leads the consumer to using a higher water flow over the true needs, and thus to waste.

It is well known the various types of ball valve batteries which incorporate in the structure of the handle elements which allow the securing of a function by presetting the handle so that the use of different water flows is effected for a more reasonable consumption. So is in the European patent EP 0 643 246 A1 presented a battery grip with ball valve, wherein in the interior of the handle, an elastic blade is provided lever-like articulated, which remains at the end of the unevenness caused by the battery body, which limits the opening of the maximum cock and thus secures a smaller stream of water through its end , To move to a larger jet of water, it is necessary to simultaneously operate the handle and a knob built into the handle to release the elastic lever-like blade from the unevenness of the valve body. The disadvantage of the solution lies in the fact that it allows a single preset position of the water flow, and that the operation with other water flows of the water jets need simultaneous operations of the handle and pressing the release button. In the structure of the handle significant changes to secure the lever-like joint appear, and the "y" shape of the elastic blade is a structural and technological complication dar. The European invention patent EP 0 426 639 A1 has, in the structure of the handle, a joining system on the faucet hub, which allows the axial displacement of the handle by screwing, and at one end of the hub to achieve preset restrictions on the flow rate of the water jet. The disadvantage of the solution consists in the fact that preset restrictions on the flow rate of the water jet can only be achieved by the engagement of the solution of the protective cover and by adjustments by screwing in with the screwdriver. Also, you need a preloaded spring, and the structural change of the hub is significant. In the European invention patent EP 1 450 088 A2 a technical solution is offered which has built in the handle an adjustable screw-lock, which can restrict the flow of water through the battery at the desired level. The desire to use flow rates other than the highest preset is possible only after the lock is set by a separate intervention of the consumer, and thus the initial setting is lost. Also, the presence of the control screw on the handle is clearly unaesthetic, despite the attempt at concealment by the activation of the handle in a manner which may affect its function.

The technical problem solved by the invention is that of optimizing water consumption according to the desire and the actual needs of the consumer, by a single operation of the handle, which can be preset in several positions, ensuring different and streamlined water flow rates without significantly affect the structure of the handle.

The pre-metered water flow handle of the invention eliminates the aforementioned drawbacks by having an elastic profiled lamellar element with a rounded end structure which allows the consumer to preset several intermediate positions of water flow through the tap, between one Minimum value and the highest possible water jet. The round end of its elastic lamellar element attached to the tap can be adjusted in a slot of the main body of the battery by a single intervention of the consumer. This relaxes a mother, regulates the desired position of the slat and pulls the mother back to. The slat remains in this position until a new setting. Between the positions thus determined, the structure also allows intermediate positions of the handle, and thus the water flow rates.

• – gestattet das Festlegen einer vorherig eingestellten Stellung für vernünftigen Verbrauch, so wie von Zwischenstellungen, aus einem einzigen Handgriff des Verbrauchers;
• – gestattet das Anpassen von elastischen Einstellungselementen, durch kleine bauartige Veränderungen des Griffs und des Hahnkörpers, die gar nicht teuer sind;
• – gestattet einen leichten Zugang des Verbrauchers, für ein Nachkalibrieren oder Ersetzen der elastischen Elemente;

The handle with pre-metering of the water flow has the following advantages:

• - allows the setting of a pre-set position for reasonable consumption, as well as intermediate positions, from a single manipulation of the consumer;
• - Allows adjustment of elastic adjustment elements, through small structural changes of the handle and the valve body, which are not expensive;
• - allows easy access by the consumer, for recalibration or replacement of the elastic elements;

Furthermore, we give an example of the invention of the pictures:

Figure 7: Partial cross section through the valve body in the slot guide from the valve body.

The handle with pre-metering of the water flow is formed according to the invention of a group of components, located on the main body 1 of the rooster on which a transverse slot 2 is provided on a radial route, according to the setting limits for hot water on the one hand and for cold water on the other side. The radial angle extension of the slot 2 allows the corresponding settings of the mixture of hot water with the cold water. The component group of the handle with predosing consists of the actual handle body 3 , which has a slot in the rear part of the battery, which is the setting of an elastic blade 4 allowed, provided with a round end which on the building 1 supports, or inside the transverse slot 2 , An adjustment nut 5 and a retaining square screw 6 ensure the desired position of the elastic blade 4 , for setting the desired flow rate. Correctly setting and eliminating the possibility of turning the screw head 6 is from the projections 7 of the guide slot from the handle body 3 secured. For firmly fixing the position of the elastic blade 4 after each adjustment, this has at the attachment end stiffening ribs, enclosing in on a surface which also has stiffening ribs, from the inside of the guide from the inside of the handle 3 , For a flow rate equal to 0 or for the maximum flow rate, he will handle 3 put in the extreme positions. For intermediate flow rates according to the actual needs of the consumer or for economical uses is partly the mother 5 unscrewed afterwards this is together with the screw 6 from the inside of the socket bounded by the bulges 7 moved in the setting position of the desired flow rate, after which the mother 6 and the screw 5 be attached again, which will allow that when operating the handle 3 the elastic lamella 4 in the version 2 will penetrate and a location of the handle 3 effect, according to a preset flow rate. This setting can have multiple layers for finely adjustable intermediate flow rates.
