DEVICE FOR PERSONAL HYGIENE The present invention relates to a device forpersonal hygiene.
According to the present invention there is provided a device for personal hygiene which comprises a body having a socket connectable to a water supply source and communicating with two ductsl one of which is connected to a cavity formed in the body and theother to amixing or release chamber also formed in the body, wherein the release chamber contains a removable soap holderihaving at least a portion of its wall located within. therelease chamber and being perforated; said release chamber communicating by means of a duct formed in the body with at least one recess communicating with the and in which a turbine" wheel is rotatably mounted and capable .of being driven by the flow of liquid issuing from the release chamber; said wheel having aspindle which passes through the body and extends into the said cavity and carries a removable brush having bristles which extend out of the body; and a flowreversing device is provided which enables the flow of waterpassing through the socket "to be rected to one or otherof the ducts connected to the said socket. I i f x v ,1 The flow reversing device may comprise a tap fitted onthe body or' onthe socket or comprise a tubular member displac'eable' within the socket having an offset passage alignable with one or other of the ducts.
The invention will be described further, byway of example, with reference to the accompanying drawings,
in which: i 1
FIG. 1 is an exploded perspective viewzof an embodiment of the device;
FIG. 2 is a longitudinal section through the device of FIG.-l; I 1
FIG. 3 is a plan view showing a detail of the device;
and t FIG. 4 is a-planview of another detail.
The device comprises a body 1 of generally truncated pyramid shape with one of the side faces thereof forming the front face 2 of'the device. A corner or edge forms the con'nection for the other two side faces 4 and represents the back of the device.
An' upper'wall 5 of the body 1 has two front recesses 6 disposed substantially along corner or edges 7 defining the limits of the front face 2 and also has a rear recess or m ixirig'or release'chamber 8 disposed substantially along the' rear edge or corner 3. Disposed on the upper wall 5 is aplate or cover 9 shutting off the front recesses 6 and having an opening 10 to overlie the chamber 8,. The side wall of this opening 10 is provided with circular grooves l 1 each having an inclined groove 12 opening out on the upper edge of the said opening 10. The mounting of the plate 9 on the body the front recesses,6.communicates via a'duct 17 with a cavity 18 formed in the lower wall 19 of the body 1 whilst the bottom 20 of the said recesses 6 is provided with an axial aperture 21 opening out into .the cavity 18.
A paddle wheel or turbine wheel 22 is located in each of the recesses 6 and iscapable of being driven by the flow of liquid through the passage 13. The turbines 22 are mounted on spindles 23, each having one end which is rotatably mounted in a bearing 24 providedon the under face of cover 9. The other end of each of the spindles 23 passes through the axial opening 21 in the bottom 20 of each recess 6 ande'xtends into the cavity 18 in the lower wall 19 of the body 1; axial opening 21 also acting as a bearing for the spindle 23. The end of the spindle 23 extending into the cavity 18 is cut with a resilient slit 25 and the end is detachably secured to a rotary brush 26. Brush 26 comprises a cylindrical body 27 having an upper face provided with an insert or inlet 28 force-fitted on the split end of the spindle 23, the resilience of which ensures retention of the unit whilst permitting the detachment of the two parts. The body 27 of the rotary brush 26 is locatedflin the cavity 18 whilst the bristles 29 are disposed beyond the cavity 18 and extend out of the body. 1.
Behind the brushes 26, i.e., near the edge 3 of the body 1, a non-rotatable, removable stabilising brush 30 is provided in the cavity 18. This brush 30 comprises a cylindrical body 31 in the upper face of which thereis formed an inlet 32 force-fitted on a split pin 33 disposed in the cavity 18. The body of this fixed brush. is located within the cavity 18 whilstthe bristles 34 are disposed beyond the cavity 18 andextend out of the body 1 as is the case for the rotary brushes 26. i
A triangular skirting brush 35 is arranged around brushes 26 and 30 and borders the cavity 18, and comprises a pad 36 having bristles 37.fitted thereto. The pad 36 is disposed in a groove 38 (FIG. 2) bordering the cavity 18, whilst the bristles 37 extend out of the cavity'at the same level as the bristles of the brushes26 and 30. The brush 35 is kept in position by the pad 36 being locked in the groove 38 by means. of a side wall 39 (FIG. 2) of a perforated plate or grid 40 disposed in the cavity 18 and comprising, three openings 41 which allow passage of the bristles of the brushes 26 and 30. The grid 40 is retained in the cavity 18 by means of a screw (not shown) engaged in a hole 42 (FIG. 4) in the centre of the grid and in a suitable thread (not shown) on the bottom of the cavity 118.
The cavity 18 communicates with the interior of the socket 15 by a duct 43 (FIG; 2) formed in the body 1 and opening out substantially between the brushes 26 and 30. The duct 43 has the same diameter as the duct 14 and is disposed symmetrically relatively to the axis of the socket l5.
The chamber 8 contains a removable soap holder 4 having a lower part which is open and comprises a perforated side wall 45 of which the lower edge is intended to be opposed against the bottom of the chamber 8. The soap container 44 has a circular joint 46 above the perforated wall 45 for ensuring the tight closure of the chamber 8, two pins 47 intended to engage in the grooves 11 in the opening 10 of the cover 9, and an operating button 48.
Slidably and rotatably engaged in the socket 15 is the closed end. 49 of a tubular member 50, the other end of which is introduced into the end of a flexible water "supply pipe 51. The end of pipe 51 is itself located in a'handle 52 having an inner collar or flange 53 forcefitted on the member so that the latter is connected to the handle 52. A tube 54 is fixed in the end 49 and communicates with the interior of the tubular member 50, this tube being calibrated and located off-centre so that it can be introduced into either of the ducts l4 and 43.
Mounted on the tubular member 50, is a bush 55 which is tapped to engage with the thread 16 of a socket and provided with a collar 56 sewing as support for a compression spring 57 engaged on the tubular member 50 and abutting a shoulder 58 thereof. A circular joint 59 located in a recess of the end 49 ensures the seal between the socket 15 and the end 49 of the tubular member 50.
The operation of the device will now be described. The water supply pipe 51 is connected by suitable means (not shown) to a conventional pressurised water distributing point, for example, as a replacement of the flexible tube of a shower forming part of a normal bathroom fitting. Before operating the device, the user withdraws the soap holder 44 after having twisted it in order to disengage the pins 47 from the grooves 11 in the cover 9. The operator can then charge the holder 44 with soap in the form of a paste or, preferably, calibrated tablets, forming a measured quantity sufficient for an individuals personal toilet. When the soap holder 44 is charged with soap, the user inserts it in the opening 10 of the cover 9 and engages the pins 47 in the inclined grooves 12 of the said cover. Subsequent rotation of the soap container 44 causes the pins 47 to engage in the grooves 11 and the soap holder is secured, the pins 47 as well as the grooves 12 and 11 acting as a bayonet connection.
When the soap holder 47 is charged, the device is ready for use and the user can turn on the water. When the tubular member 50 and the tube 54 are in the position shown in FIG. 2, the water flowing under pressure through the pipe 51 passes into the tubular member 50, into the tube 54 and duct 14 and then flows into the release chamber 8 and, whereupon the water becomes charged with soap because the wall 45 of the soap container is perforated. It should be pointed out that, since the soap is in the release chamber 8, it is continually bathed in water and mixed thereby, the water which leaves the release chamber is heavily emulsified with soap. Moreover, since the soap is contained in the soap holder, it cannot amalgamate (mix) at the inlet of the ducts l3 and possibly block them. From the release chamber 8, the soapy water flows through the ducts 13 to issue under high pressure into the recesses 6 where it drives the wheels 22 before escaping into the ducts 17 to pass into the cavity 18. The rotation of the wheels 22 causes rotation of the brushes 26. The soap charged water passes from the ducts 17 and into the cavity 18 and flows out thereof through the perforations of the grid 40 whence it passes to the brushes 26 and 30. The brushes 26 vigorously agitate the water whilst the brush 35 acts as a jet brake or skirt and acts to prevent the soapy water being projected out of the side of the brush.
An abundant lather is produced because the water passing through the duct 18 is continually stirred-up during its passage through the release chamber 8, the ducts 13, the wheels 22, the ducts 17, the brushes 26 and the grid 40. Due to the rotation of the brushes 26 an efficient scrubbing action is readily obtained, which also produces a massage effect. The combination of the rotary brushes 26 with the fixed brush 30 enables the device to be stabilised when it is in contact with the skin since the fixed brush 30 counterbalances the effect of tangential forces due to the rotation of the brushes 26. When the measured amount of soap in the conminer. 44 is exhausted, the device then supplies the clear water only which rinses the entire device and the user rinses himself whilst continuing to scrub himself, if desired. Alternatively, the user has the possibility of shutting off the supply of soapy water at any moment even if the soap in the container 44 has not been exhausted. In order to do this, it is only necessary to pull the handle 52, the effect of which is to displace simultaneously, and in the same direction, the tubular member 50 against the action of the spring 57. The tubular member 50 involves, in its displacement, the tube 54 which is thus extracted from the duct 14. It is then necessary to rotate the handle 52 through 180 about its axis in order to move the tubular member and to bring the tube 54 opposite the duct 43. Release of the handle 52 at this moment causes the spring 57 pushes back the shoulder 54, thus driving the tubular member 50, the handle 52 and the tube 54 which is thereby introduced into the duct 43. The water supplied by the pipe 51 and flowing through the tubular member 50 and the tube 54 is directed into the duct 43 and thus flows into the cavity 18 and out thereof through the perforations of the grid 40 whereupon it passes into the brushes 26 and 30. In this operation, the water avoids the circuit through the duct 14, the release chamber 8 and the soap holder 44 and the device supplies clear water. In order to have soapy water available again it is only necessary to perform the operation in reverse.
The method of attachment of the brushes 26 and 30 and the brush 35 enables such to be readily interchanged.
The device described may be made of any suitable material, and although it is shown with a body in the form of a truncated triangular pyramid, this form is not a limitation and may be modified. Moreover, the number of rotary brushes must not be considered as limited to two and it is possible to produce a device comprising only one rotary brush or more than two brushes. Moreover, the fixed brush 30 may be omitted and replaced by two or more fixed brushes. As to the brush 35, this may be omitted, although is preferably retained in the various embodiments of the device, since it constitutes an efficient means to brake the water jet making it possible to prevent troublesome side projections of water whilst at the same time ensuring a scrubbing action.
Finally, the flow diverting system which makes it possible to change from the supply of soapy water to a supply of clear water and conversely (and comprising the assembly of tubular member 50, spring 57 and tube 54), may be replaced by any other flow control means, such as, for example, a cock casing, or any other type fitted on the socket 15 or on the body 1, for example, near the release chamber 8, and in such manner as to divert the flow to one or other of the ducts 14 and 43.
