[0001] The present invention relates to a delivery device with adjustable position ejector,
particularly adapted to be used for hydro-massage baths.
[0002] It is well known that in the hydro-massage baths a plurality of delivery devices
are provided, conveying to the body of the person immersed in the bath a flow of pressurised
water to which air is added.
[0003] Each delivery device is provided with an adjustable position ejector allowing to
direct the flow at will of the user.
[0004] The ejectors can be oriented manually by the user and this has the drawback of needing
continuous interventions by the user any time he wants to modify the jet direction.
[0005] Other versions intended for hydro-massage baths of high cost and therefore for professional
use are also known, that still have the manual regulation of the spraying direction
of the ejectors but allow a servo-assisted regulation of the delivered flow.
[0006] Irrespective of the kind of hydro-massage baths, movement of the ejectors is obtained
by articulation means consisting of two or more mechanical elements pivotally coupled
for instance through ball joints, connecting each ejector to the corresponding water
supply tube.
[0007] All the known delivery devices therefore have a first drawback consisting of the
complex construction of said articulation means.
[0008] Consequently said delivery devices have also the further drawback of a high manufacturing
cost and therefore a high selling price.
[0009] Another drawback consists also in that, in view of of the complex construction of
said articulation means, the operational reliability of the delivery device is rather
low and the user is obliged to frequent maintenance interventions.
[0010] Another drawback consists in that, since said articulation means comprise several
pieces pivotally connected to each other, they show even deep gaps and sometimes undercut
areas that being in contact with water cause deposit of organic residues coming from
exfoliation of the skin of the person undergoing the hydro-massage treatment.
[0011] This causes lower hygienic conditions during the treatment and the need to carry
our regularly the disinfection of the bath and of the whole water delivery system.
[0012] A last but not least drawback consists in that use of said articulation means increases
the dimensions of each delivery device and this generally causes greater overall dimensions
of the bath and assembling and disassembling difficulties during installation and/or
any maintenance operation.
[0013] The present invention aims to overcome said drawbacks.
[0014] More particularly an object of the present invention is to provide a delivery device
that for adjusting the ejector position does not require use of articulation means
consisting of two or more mechanical elements pivotally connected to each other.
[0015] Another object consists in that servo-assisted actuators can be easily associated
to the delivery device of the invention for adjusting the spout direction and flow
rate.
[0016] A further object is that the delivery device of the invention is less prone to deposit
of organic residues in comparison with the known devices.
[0017] Another object is that the delivery device of the invention has a greater reliability
of operation in comparison with equivalent devices of known type.
[0018] A last but not least object is that the delivery device of the invention has also
lower dimensions relative to equivalent known devices.
[0019] The foregoing objects are attained by providing a delivery device particularly adapted
to be used in hydro-massage baths that according to claim 1 comprises at least an
ejector hydraulically connected to at least an outer duct supplying a liquid to be
delivered and mechanically connected by interposition of articulation means to driving
units adapted to put it in motion, and is characterised in that said articulation
means comprise at least an annular surface made of a yielding and elastic material
arranged between a first annular collar defining the outlet of said device and a second
annular collar mechanically connected internally to said ejector and externally to
said driving units.
[0020] According to a preferred embodiment the annular surface, the first collar and the
second collar belong to a single tubular element fully made of yielding and elastic
material, provided with a first inlet way for connection of an outer duct supplying
the liquid to be delivered and a second inlet way for connection of an outer duct
supplying a gaseous fluid.
[0021] The delivery device comprises also shutting means to intercept and regulate the flow
of liquid to be delivered through said device.
[0022] More particularly said interception and regulation means comprise a pusher put in
motion by displacement means, acting outside on the tubular element so as to modify
the passage section by elastic deformation.
[0023] The displacement means of said pusher and the driving means of the ejector generally
comprise cam means associated to an electric motor.
[0024] More particularly a couple of cam means are associated to the ejector, said cam means
being in turn associated to corresponding driving means arranged at right angles to
each other allowing to traverse the ejector along planes perpendicular to each other.
[0025] Both motors of the driving means are electrically connected to an electronic control
board that combining properly the traverse motion of both means generates a rotary
motion of the ejector with space development.
[0026] In a similar way the same electronic control board is electrically connected to the
displacement means to vary the delivery of the ejector from the closed position to
the maximum opening position.
[0027] Advantageously the delivery device of the invention allows a greater hygienic condition
of the hydro-massage baths and requires less maintenance and cleaning interventions.
[0028] Still advantageously the delivery device has also lower dimensions and costs in comparison
with equivalent known delivery devices.
[0029] The foregoing objects and advantages will be better understood from the following
description of a preferred embodiment of the invention which is given as an illustrative
and non limiting example making reference to the accompanying sheets of drawings in
which:
- Figs. 1 to 3 show the delivery device of the invention in three different isometric
views;
- Fig. 4 is a top view of the delivery device of Fig. 2;
- Fig. 5 is a partial sectional view of the delivery device shown in Fig. 4 taken along
the section line V-V;
- Fig. 6 is a left side view of the delivery device of Fig. 4;
- Fig. 7 is an exploded view of a part of the delivery device of the invention; and
- Fig. 8 is an isometric view of part of the delivery device of the invention.
[0030] The delivery device of the invention is shown in the isometric views of Figs. 1 to
3, where it is generally indicated with reference numeral 1, and also in Figs. 4 and
5 where it is shown in a partial sectional view.
[0031] Moreover the device can be seen also in the general view of Fig. 6 and in the exploded
view of Fig. 7 showing only some of its components.
[0032] The delivery device 1 is particularly adapted to be used in hydro-massage baths and
comprises an ejector 2 hydraulically connected to an outer duct C1 supplying a liquid
to be delivered, which is mechanically connected through articulation means generally
indicated with numeral 3 to driving units generally indicated with numeral 4 adapted
to put it in motion.
[0033] According to the invention the articulation means 3 comprise an annular surface 5
made of yielding and elastic material, arranged between a first annular collar 6 defining
the outlet 7 of the device and a second annular collar 8 mechanically connected internally
to the ejector 2 and externally to said driving units 4.
[0034] More particularly one can see that the annular surface 5, the first collar 6 and
the second collar 8 belong to a single tubular element 9 which is fully made of yielding
and elastic material, preferably but not necessarily an elastomer such as rubber or
its mixes.
[0035] In the tubular element 9 a first inlet way 10 for connection to an outer duct C1
supplying the liquid to be delivered, preferably water, and a second inlet way 11
for connection to an outer duct C2 supplying a gaseous fluid, are defined.
[0036] It is to be pointed out that said gaseous fluid is preferably but not necessarily
air, which could be replaced or integrated with medical gases of various type.
[0037] Water entering through the first inlet way 10 is mixed with the gaseous fluid entering
through the second inlet way 11 and goes out through the ejector 2 conveying it to
the body of the person immersed in the bath.
[0038] It is the combination of the effect of pressurised water together with the gaseous
fluid dissolved in it that carries out the hydro-massage by Venturi effect.
[0039] The tubular element 9 is removably received in a holding structure 12 constituting
the body of the device 1 and used to fix the delivery device to the bath.
[0040] The holding structure 12 is also used to support the driving units 4 for the articulation
of the ejector 2, which are externally connected to the second annular collar 8 through
an annular ring 13 that can be seen in greater detail in Figs. 7 and 8.
[0041] More particularly one can see that the annular ring 13 is provided with ring nuts
14, 15 arranged orthogonally to each other, each of them receiving the connection
of one of the driving units 4.
[0042] Each driving unit 4 comprises a cam 16, 17 provided with a screw 18, 19 of connection
to the corresponding ring nut 14, 15 and having a shaped outline 16a, 17a, slidingly
co-operating with a pin 20, 21 eccentrically arranged in a disc 22, 23 coupled to
the shaft 24, 25 of a corresponding electrical motor 26, 27.
[0043] When the motors 26, 27 are fed, sliding of each pin 20, 21 on the shaped outline
16a, 17a, of the corresponding cam 16, 17 causes a displacement 28, 29 of the cam
on the plane α, β containing the cam shown in Fig. 1 and also in the schematic view
of Fig. 8.
[0044] As each cam 16, 17 as already stated, is fixed to the annular ring 13, each cam transmits
its displacement to the second annular collar 8 to which is connected and therefore
to the ejector 2 that is nip inserted in the annular collar 8.
[0045] More particularly, looking at Fig. 8 it is to be noted that the displacement 28 of
cam 16 gives to the annular ring 13 a rotation around the axis Y laying on plane β
and passing by the ring nut 15 of connection of cam 17 and in the same way the displacement
29 of cam 17 gives to the annular ring 13 a rotation around axis Z laying on plane
α and passing by the ring nut 14 of connection of cam 16.
[0046] Yield and elasticity of the material of the annular surface 5 connecting the first
annular collar 6 to the second annular collar 8, thus allows ejector 2 to oscillate
both on plane α and plane β with a traverse motion occurring on both planes relative
to a theoretical rotation centre O which is placed substantially at the centre of
ejector 2, at the point of intersection of the axis X, Y and Z as shown in Fig. 8.
[0047] More particularly in this way an oscillatory motion around the point O is obtained
for ejector 2, on the plane of the drawing of Fig. 5 according to opposite directions
indicated by arrow 28 and on the plane of the drawing of Fig. 4 according to the opposite
directions of arrow 29.
[0048] Both motors 26, 27 are electrically connected to an electronic control board not
shown in the drawings, which drives properly the speed of both motors, combines the
oscillating motions of the ejector 2 so as to generate for said ejector 2 a curved
space motion around the rotation centre O allowing to orient the spout in any direction
desired by the user.
[0049] Use of the electronic control board allows a fine regulation of the oscillations
of ejector 2 and the presence on the disc 22, 23 of each motor 26, 27 of a magnetic
element 31, 32 co-operating with a relevant fixed sensor not shown in the drawings,
allows detection of the number of the revolutions of each motor as well as the angular
position of each cam and therefore of the ejector 2.
[0050] Therefore through the control board it is possible to carry out the following steps:
traverse ejector 2 on plane α; traverse ejector 2 on plane β; combine the two traverse
motions so as to obtain a space rotary motion of the ejector 2; change the spraying
position of the ejector setting it along different directions at choice of the user.
[0051] The delivery device comprises also a pusher 40 that can be seen particularly in Fig.
4, acting externally on the tubular element 9 at a zone 9a of said element, comprised
between the first inlet way 10 supplying water and the second inlet way 11 supplying
the gaseous fluid.
[0052] The pusher 40 is associated to a displacement unit generally indicated with 41, adapted
to move it in a rectilinear direction along the lines opposite to each other indicated
by arrow 42.
[0053] Like the driving units for the ejector 2, the displacement unit 41 comprises a cam
43 on the inner profile 43a of which a pin 44 is slidingly contacted, belonging to
a disc 45 fixed and caused to rotate by the shaft 46 of an electric motor 47.
[0054] In such a way the cam 43 converts the rotary motion of shaft 46 of motor 47 in a
vertical motion of pusher 40 causing the formation of the tubular element 9 at the
contact zone 9a that can be deformed according to the configuration 9b when it is
desired to intersect totally the flow through the ejector 2.
[0055] Magnetic elements 48 are provided also in the disc 45, co-operating with fixed sensors
to detect and define the position of pusher 40 and vary the flow rate of the ejector.
[0056] Driving properly rotation of the motor 47 through the mentioned electronic control
board, it is possible to vary the position of pusher 40 so as to modify the shutting
degree of the tubular element 9 and therefore water delivery through ejector 2.
[0057] From the foregoing it is clear that the invention attains all the intended objects.
[0058] Firstly, connection of ejector 2 to the driving units 4 occurs without using mechanical
articulation means consisting of two or more mechanical elements pivotally connected
to each other because the single yielding element consists of the annular surface
5 made of elastomer.
[0059] This makes easier construction and more reliable operation of the ejector.
[0060] Moreover, gaps or undercuts are eliminated and therefore, as shown in Fig. 5, the
contact of water from the supply duct C1 to the ejector 2 continues without meeting
discontinuity zone where it is possible collection of polluting material.
[0061] Therefore, a delivery device is advantageously obtained warranting a greater hygienic
condition, more reliable operation and less expensive in the manufacturing stage.
[0062] In the constructional stage many modifications other than the solutions described
and shown in the drawings could be made to the delivery device of the invention.
[0063] It is however to be understood that when said modifications fall within the scope
of the appended claims, they should be all considered covered by the present invention.
