Definitions

  • the present invention relates to a handshower for the dispensing of water of the type having multiple secondary outlet conduits; in particular, it relates to a handshower of this type equipped with a flow selector to deviate the single supply flow onto the desired one among secondary conduits.
  • handshowers of the most diverse shapes and operation modes are employed to dispense water.
  • the handshower can be used in different ways, it has now become common practice in the field to provide a dispensing head with differentiated flows, for example one having a single central jet and a plurality of smaller jets circumferentially arranged.
  • the handshower also features a manoeuvring member or a selector mechanism which allows the user to choose the water dispensing mode.
  • the selector mechanism provides to interrupt the water supply main flow and to direct it, according to the user's choice, towards an outlet nozzle or to another nozzle through respective delivery conduits.
  • Selector mechanisms can be roughly divided into two main categories: those arranged in and integral with the dispensing head - which may be operated by a rotating coupling ring which couples in a differentiated way two selection plates - and those located on the handshower handle - which are normally operated by levers or push-buttons.
  • the mechanisms of the first type are preferable from a functional point of view, because they allow wider adjustment possibilities, being able to exploit the coupling between two plates varying their position over a complete 360° rotation.
  • the coupling ring structure requires such mechanisms to be arranged directly on the dispensing head: from an operation point of view, the user is hence forced to act on the head, thereby interfering with the water outlet area; these selection systems are therefore employed in showers only.
  • the mechanisms of the second type are instead subject to a significant functional limitation, since they are mounted on the handle in the shape of levers or push-button switches, and do not offer the opportunity to exploit many different settings.
  • a switch lever such as the one illustrated in US 4.629.124 in the name of Hansa Metallwerke AG for example, can be operated choosing between two settings only.
  • the setting selection direction must necessarily be reversed to change from one setting to the other, which is not welcome, both from the point of view of the dimensions and of the operation thereof.
  • a push-button or of a selection lever which can be comfortably pushed to select a certain setting, but which must then be uncomfortably lifted to bring it back to the original setting; or of a lever which can be shifted about the longitudinal axis of the handle, the rotation of which, for a left-handed person, can be comfortable in one direction but not in the opposite one.
  • fig. 1 there is represented a portion of a handle 1 for a handshower.
  • a water supply duct (not shown) is intended to be coupled, while at the other outlet end 1b a dispensing head (not shown) is engageable and capable of letting the water flow out through a series of nozzles which may be alternatively selected.
  • the dispensing head provides up to four different water delivery conduits and, correspondingly, the outlet end 1b features four distinct outlet ports 1c (fig. 1A).
  • the handle 1 in particular, consists of a cylindrical housing 2, slightly curved to facilitate an ergonomic grip, inside which are housed an entry insert body 3, an outlet insert body 4, and a selector mechanism 5.
  • the entry insert body 3 has the shape of a tubular supply body, with a larger diameter at one coupling end 3a by which it protrudes from the housing 2.
  • the coupling end 3a is precision-fitted at the mouthpiece of the housing 2 with the interposition of an O-ring-type seal 6.
  • the tubular supply body 3 ends inside the housing 2 with a circular flange 3f from which projects, in the upper part (in fig. 2A), a guide and sliding element 7, open downwards with an upturned U shape (in fig. 2A), the function of which will be discussed further on.
  • a similar outlet insert body 4 is coupled with the mouthpiece of the housing 2 by interposing a pair of watertight O-ring seals 8 and 9. Within the outlet insert body 4 are obtained the four channels 1c, mutually parallel and circumferentially equidistant.
  • a threaded pin 10 which extends inwardly in a longitudinal direction, terminating in a manoeuvring head, for example a screw head 10a.
  • a ceramic disc 11 Onto the pin 10 is fixed a ceramic disc 11, which features four holes 11a in correspondence of the mouthpieces of the channels 1c.
  • the disc 11 is fixed and adheres to the end surface of the insert body 4 and hence the holes 11a represent the mouthpieces and a junction surface of the channels 1c.
  • the holes 11a feature a slightly countersunk surface (as can be seen in fig. 2A) representing a connecting surface for the water throughflow.
  • a second ceramic disc 12 is further mounted, free to rotate, equipped with two dispensing ports 12a, mounted integral with a tubular control body 13.
  • the tubular control body 13 is engaged in a seat 3b of the tubular supply body 3, where it is rotatingly supported.
  • a PTFE ring 13g is provided between the two pieces, in order to avoid friction and chafing which would cause component wear; the seal between the pieces 13b and 3b is guaranteed by a lip seal.
  • the front coupling of the two ceramic discs 11 and 12 has proved particularly effective in guaranteeing a sliding seal without the need to interpose any gasket.
  • the rotation of the ceramic disc 12, equipped with two dispensing ports 12a, against the fixed ceramic disc 11 achieves the desired selection, since it leads the dispensing ports 12a - communicating with the inner room of the tubular control body 13, which in turn communicates with the inner room of the tubular supply body 3 - alternatively in communication with one of the four holes 11a of the four distinct channels 1c.
  • the pair of the two coupled and mutually rotating ceramic discs is already known per se and is commonly called ceramic cartridge of the handshower.
  • the cartridge of the two discs 11 and 12 and the tubular control body 13 form the selection mechanism together with the operating member 5, which is illustrated in the following.
  • the tubular control body 13 features a first cylindrical portion with a larger diameter 13a adjacent to the ceramic disc 12 integral therewith.
  • the tubular control body further features a second portion with a smaller diameter 13b which protrudes from the first portion 13a and engages, as said above, into the seat 3b of the supply body 3.
  • On the outside of this smaller-diameter portion 13b a series of saw teeth 14 are obtained having the shape of a complete circular toothing.
  • a fork-shaped push-button 15 is further provided, equipped with a pivoting dog spike or pawl hook 16.
  • the fork-shaped push-button features a thickened base portion 15a, which protrudes from the housing 2 through an opening 2a, and two side wings 17a and 17b, tapered at their ends, which enclose sideways the smaller-diameter portion 13b.
  • the two wings 17a and 17b are arranged and sized so that they can slide, in a crosswise direction to the longitudinal axis of the handle 1, between the housing 2 and the walls of the guide element 7 (fig. 3). In this way the push-button 15 is free to slide crosswise to the handle, covering a total stroke of about 6 mm, but it cannot rotate about the longitudinal axis.
  • the dog spike comprises a hook 16 mounted pivoting on a pin integral with one of the two wings, for example the right hand wing 17a.
  • the hook is housed in a well provided within the wing 17a, so that the pivot pin is supported, in the wing 17a, at both its ends.
  • the hook 16 is arranged laterally offset in respect of the toothing 14 of the control body 13 and is kept radially driven inwards - so as to engage with the saw teeth - by suitable elastic means, for example by a plastic material flap 18.
  • the side wings 17a and 17b are partly interrupted to make room for two thrust springs 19a and 19b which are restrained, on one side, against an abutting surface (not shown in the drawings) of the push-button 15 and, on the other side, against the inner surface of the housing 2. In this way the push-button 15 is kept driven towards the outside of the housing 1.
  • the springs 19a and 19b are arranged in an anti-symmetrical position, as shown in fig. 5, because this arrangement provides the best equilibrium of the forces acting on the push-button 15.
  • the push-button 15 is made to slide (active run) towards the inside of the handle (arrow F in fig. 3) acting on the operation push-button 15a to oppose the action of the springs 19a and 19b (in fig. 2B the push-button is shown at an end stop with the spring 19b compressed).
  • the hook 16 is itself shifted in the direction of the arrow F, causing the rotation of the toothing 14 according to arrow R - and therefore of the control body 13 - by a preset angle: this angle is for example about 45° for a maximum 6-mm stroke of the push-button 15.
  • the push-button 15 is newly driven outwards by the springs 19a and 19b (passive run) and the hook slides over the toothing 14, oscillating backwards against the elastic force of the flap 18, until it is newly engaged with a successive tooth.
  • this run is substantially passive, since the dog spike is not capable of causing the control body 13 to rotate, which hence remains stationary.
  • the rotation of the control body 13 causes, in turn, the rotation of the ceramic disc 12 in respect of the ceramic disc 11, achieving the desired setting selection, that is, connecting the supply conduit 3 with the desired one of the channels 1c, by coupling one of the respective holes 11a with one of the two dispensing ports 12a.
  • the inlet ports 11a are four, mutually angularly spaced apart by 90°, while the dispensing ports 12a are two and mutually angularly spaced apart by a suitable angle, so that, at each relative 45° rotation - i.e. following each pressure on the push-button - it is possible to change the setting and thereby the function of the distributor.
  • a selection mechanism has in fact been provided which allows to intervene through an adjustment control always in the same direction (i.e. by repeatedly pushing button 15, which is brought back into its home position by springs 19a and 19b). Furthermore, the mechanism of the invention allows to perform the selection over a full, 360° circumferential path, hence with the possibility of deviating the main flow onto multiple different secondary conduits, as many as can be housed in a full disc having a diameter equivalent to the section of the handshower handle.
  • the operation push-button 15a being arranged along the handshower handle, is easily accessible by the fingers of a hand without having to interfere with the flow of water dispensed by the headpiece of the handshower.
  • the ceramic disc 11 is provided as a self-contained piece successively mounted integral with the insert body 4 made of plastic material.
  • the ceramic material has proved particularly suitable to achieve the watertight rotation coupling which must be established with the distributor disc 12.
  • a different configuration is not ruled out.
  • saw toothing is intended to mean any arrangement of notches or recesses on the outer surface of the control body 13 which allows it to be rotation-driven by the dog spike 16 only in one displacement direction of the push-button 15.
  • the push-button has always been illustrated arranged so as to protrude underneath the handle - i.e. on the same side where water is dispensed by the head of the handshower - its orientation can be chosen depending on other criteria, for example it could protrude above or sideways of the handle depending on the applications.
