Description

A shower device

FIELD OF THE INVENTION AND PRIOR ART

This invention relates to a shower device for a toilet seat, com¬ prising a shower head, a water supply conduit leading thereto, and a carrier on which the shower head and at least a portion of the conduit are arranged and which is movably arranged in re¬ lation to a support construction to move the shower head in a pivoting movement between an active position in which the shower head is located to give a person sitting on the toilet seat a shower from beneath in his or her seat region, and an inactive position in which the shower head is brought aside.

The term "give a shower" here used should be seen in a wide perspective. Accordingly, it is supposed to comprise anything from a well spread shower to a rather concentrated spraying or washing. The invention also includes that the shower head is variable in the meaning that the character of the shower can be adjusted in a way known per se or optionally. At a known device of the type mentioned above the carrier is turnably arranged around a horizontal axis, which will lead to the shower head being pivoted in a vertical plane. This gives the disadvantage in that the spraying direction of the shower head will vary as a function of the turning position of the turnable carrier around the horizontal axis. Apart from this being felt as unsatisfying from a cleaning point of view it can also render the user the very un- comfortable consequence in that unintentionally misdirected shower streams will soak clothes, assisting persons or other objects in the surrounding. Furthermore, it has turned out to be difficult for the user to get control over the position and the di¬ rection of the shower head at any given time. As the shower head, as a consequence of the turnability of the carrier around a horizontal axis, will describe an arc-shaped pivoting movement in a vertical plane, it is difficult to obtain an optimum weighing of the movement path of the shower head so that, on one hand, the shower head is in optimum position where it is to be used for shower purposes, and, on the other hand, the shower head is positioned in a well distanced, protected position when it is not to be used. Finally, a tumable embodiment of the carrier ac¬ cording to the known technique also reach a rather high cost for the construction of manoeuvring handle, water regulation valve and the bearing, and the support thereof.

SUMMARY OF THE INVENTION

The object of the present invention is to further develop the in- itially stated prior art in such a way that the shower device as¬ sociates an uncomplicated and thereby cheap constructional embodiment with good manoeuverability.

According to the invention this object is obtained by the carrier, and thereby the shower head, being pivotable around a gener¬ ally vertical axis to effect the pivoting of the shower head in a generally horizontal plane of pivoting.

Accordingly, the spraying direction of the shower head will thereby be generally the same during the whole pivoting move¬ ment, which reduces the risk for unintentional showers in wrong direction. Furthermore it becomes substantially easier for the user or an assisting person to manoeuvre the carrier and thereby set the shower head in its optimum position when the carrier is pivotable around a vertical axis in a way according to the invention. Finally, this pivotability also leads to a relatively uncomplicated embodiment as a consequence of the whole carrier being pivotably positioned on the support construction and the water supply system, that is the shower head, the water supply conduit and a valve for regulating the water supply, be¬ ing positioned on the very carrier.

In the dependent patent claims advantageous further develop- ments of inventions are defined. These further developments will be further discussed in detail hereinafter. However, espe¬ cially the gadget presented in claim 6 should be mentioned, where the carrier along with the shower head and the conduits belonging thereto form a double-arm lever, on a first arm of which the shower head is arranged and on a second arm of which the handle is arranged.

Furthermore an advantageous embodiment is defined in claim 1 1 , which embodiment sees to that the movement of the shower head will be composed of pivoting movements around two dif¬ ferent, generally vertical axes, which gives more possibilities for the user or an assisting person to set the shower head.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The embodiment according to Figs. 1-5

The shower device according to the invention comprises a shower head, a water supply conduit 2 leading thereto, and a carrier 3 on which the shower head 1 and at least a portion of the conduit 2 are arranged.

The carrier 3 is movably arranged in relation to a support con¬ struction 4 to move the shower head 1 in a pivoting motion be¬ tween an active position, seen in Figs. 1 and 2, in which the shower head is located to give a person sitting on the toilet seat, which is generally referred to with 5, a shower from be¬ neath in his or her seat region, and an inactive position, as seen in Fig. 3, in which the shower head 1 is brought aside. The carrier 3, and thereby the shower head 1 , are pivotable around a generally vertical axis 6 to effect the pivoting of the shower head 1 in a generally horizontal plane of pivoting.

The device comprises a mantle 8 protruding down into a bowl 7 of the toilet seat. In the example, this mantle has a tube-like shape. In its active position, the shower head is, as seen from above, located within the width of the lower opening of the mantle 8, and in its inactive position the shower head is located beside this width. More precisely, the shower head 1 is thereby supposed to be located as in Fig. 3, that is in-pivoted behind a rear portion of the mantle 8, so that a person sitting on the toilet seat can execute his or her needs that are normally executed on the toilet seat without the shower device, and particularly the shower head 1 thereof and the conduit running up to the latter, being in the way.

A valve 9 for regulation of the water supply to the shower head 1 is arranged on the pivotable carrier 3.

A handle for manoeuvring the pivoting movement of the carrier is arranged on the pivotable carrier 3.

In the illustrated example, the valve 9 or at least a part thereof forms the desired manoeuvring handle. In the example the valve 9 comprises a moveable manoeuvring member 10. It is this movable manoeuvring member 10 of the valve 9 which forms the manoeuvring handle for the carrier 3 in the example.

In the example, the manoeuvring member 10 for the valve 9 is designed as being turnably moveable. This is no necessity, and the moveable manoeuvring member 10 can be moveable in other aspects for water regulation. In the case of a turnable manoeuvring member, it is pointed out that this does not need to be turnable around a generally vertical axis, as can be seen from the drawing figures, but that the turnability could take place around turning axes orientated in another way. However, it has turned out to be possible to obtain not only good water regulation, but also good manoeuvrability for the very carrier by means of a manoeuvring member which is turnably arranged around a generally vertical axis and which also forms a ma- noeuvring handle for the carrier 3. The carrier 3, along with the shower head 1 with the conduit 2 belonging thereto, form a double-arm lever, on one arm 11 of which the shower head 1 is attached and on the other arm 12 of which the handle 9, 10 is located.

The pivot axis 6 of the carrier 3 is located outside an edge 14 which delimits the opening 13 of the toilet seat 5.

The water supply conduit 2 extends over the toilet seat edge 14 and is movable inside a space 15 between this edge 14 and a part 16 which forms a sitting surface and is arranged there¬ over. Normally, this one has the character of a seat ring.

In Fig. 4 it is illustrated how the mantle 8 projects down into the toilet bowl 7 and how the conduit 2 running to the shower head 1 will pass over the toilet bowl edge 14 and thereafter extend obliquely downwards in the toilet bowl between the inside of the latter and the mantle 8, the conduit 2 in the nearness of the shower head 1 being bent so that the end portion of the conduit extends upwards and will be ended by the shower head 1. To obtain an embodiment which is advantageous from a hygienical point of view, this one can present easily mountable and de¬ mountable shower mouth pieces of disposable character or of an easily cleanable design.

The support construction 4 is attachable to the toilet seat 5 by means of the attachment members 18 (see Fig. 1) which also attaches the part 16, which forms a sitting surface, to the toilet seat. These attachment members 18 normally have the charac¬ ter of shafts projecting into and/or through holes arranged in the toilet seat edge behind the toilet bowl 7. These shafts can either present means which by means of friction engage with the limitation walls in the holes in the toilet bowl edge or, alter- natively, these shafts can extend totally through the holes and, at the bottom, be engaged with nuts or other fixing elements. As can be most clearly seen in Fig. 5, the support construction 4 presents holes or slots 19 arranged to be protruded by the de¬ scribed attachment members 18, so that the portion 20 present- ing the holes or slots 19 will be fixed by the support construc¬ tion 4 against the toilet seat in a position between the upper edge surface thereof and portions of the attachment members 18 or parts belonging to the seat ring unit 16.

As can be seen in Figs. 2 and 3, the seat ring 16 can be a tilt- able lid 21. As can be seen in Fig. 1 , the seat ring 16 with the mantle 8 belonging thereto can be tilted up while the attach¬ ment members 18 still retain the seat ring 16 in relation to the toilet seat.

The mantle 8 is fastened in relation to the part 16 forming a sit¬ ting surface. According to a possible embodiment the mantle 8 could be designed in one piece with the part 16 which forms a sitting surface. According to the embodiment shown in the Fig- ure the mantle 8 is, however, arranged to have the character of separate part or additional part which, by means of holders 22, is fixed to the underside of the part 16 which forms the sitting surface. The holders 22 may have the character of blocks which, by means of screws or the like, are fixed to the part 16 which forms the sitting surface. Thereby, the blocks 22 may en¬ gage maintainingly with a flange 23 arranged on the mantle 8.

According to a preferred embodiment the holders or blocks 22 form distance members which locate the underside of the part 16 which forms the sitting surface at a level above the upper surface of the edge 14 of the toilet bowl, so that the already de¬ scribed space 15 is formed therebetween. In the alternative embodiment already mentioned, where the mantle 8 is designed in one piece with the part 16 which forms the sitting surface, it is preferred that the distance keeping members are designed in one piece with the part 16 which forms the sitting surface as projections from the latter, whereby it is of course equivalent to, instead, provide the space 15 by means of a recess designed in the underside of the part 16 which forms the sitting surface.

As can be seen from the figures the support surface 4 has the character of an angled arm, where one shank forms the portion 20 which presents the holes or slots 19 for attachment to the toilet seat, while the other shank is connected with its outer end to the carrier 3 through a hinge which forms the vertical pivot axis 6. In the example, the hinge is formed by a tap or bolt extending to said shank and a portion of the carrier 3.

The support construction 4 can be composed by two parts 24, 25, which are interconnected by means of a fixing member 26, for example a bolt or screw. Alternatively, the support construc¬ tion 4 also can be formed by one single material piece. The valve 9 is fixed to the carrier 3 at a distance from its pivot axis 6 in relation to the support construction 4. As is most clearly shown in Fig. 5 the valve 9 presents a valve housing 27, in which the valve member which is moveable by means of the manoeuvring member 10 can be brought to act opening or throttling regarding the water supply to the shower head 1.

The conduit, which is generally referred to with 2, comprises a rigid portion 28 which extends from the valve housing 27 to the shower head 1 with the illustrated, bent shape, the conduit ex¬ tending through a support 29 arranged on the carrier 3 for the conduit. In the example, this support 29 has the character of a flap of the carrier, which flap is bent downwards and which is provided with a hole for passage of the conduit with relatively tight fitting.

Moreover, the conduit 2 comprises a portion 30 which extends from the valve housing 27 to a suitable water resource. Even if, in reality, other embodiments can be possible, a preferred em¬ bodiment is that the conduit portion 30 is formed by a flexible hose which extends to a mixing aggregate which is arranged at a suitable place, for example at the wall beside the toilet seat, and is arranged to mix hot and cold water in required portions, so that a pleasant temperature of the water leaving the shower head 1 can be obtained. Thereby, the mixing aggregate is suit¬ ably of thermostatical type. By such an embodiment the valve 9 is a simple volume regulation valve without capacity to mix cold and hot water. According to an alternative embodiment of the invention it would, however, be possible to arrange a mixing valve, for instance of thermostatical type, on the carrier 3, something which requires that cold and hot water conduits are drawn to this valve.

The shower device is used in the following way: when a person is to execute his or her needs at the toilet seat the shower de¬ vice is located in the position according to Fig. 3, that is with the shower head 1 pivoted outside the width of the lower open- ing of the mantle 8. As said needs accordingly have been exe¬ cuted, the user can use the shower device for cleaning pur¬ poses. Thereby, the user initially sees to that a certain water spraying takes place so that the right temperature of the water reaching the shower head 1 can be obtained. Thereafter the user can comfortably pivot the shower head 1 forward to a re¬ quired position by pivoting the carrier 3 around the axis 6. As the right position has been obtained, the user can easily open the valve 9 to a required degree, and thereby, through the shower head 1 , a pleasant cleaning shower is obtained at the required place. As the user finds that the cleaning operation has obtained the required result, the valve 9 is shut and the carrier 3 is pivoted so that the shower head 1 once again is located in the position according to Fig. 3. The embodiment according to Fig. 6

In Fig. 6 an alternative to the already described embodiment is illustrated. In Fig. 6 the same reference numerals will be used for the same or similar parts as in the foregoing embodiments, but only with the addition of the letter a .

In Fig. 6 the support construction 4a is shown as formed by two parts 31 , 32, which are moveable in relation to each other and the first 31 of which forms a base part which is attachable to the toilet seat, while the other 32 is pivotable in relation to the base part around a second, generally vertical axis 33. The carrier 3a is pivotably arranged in relation of the second part 32 around the generally vertical axis 6a first mentioned.

The two axes 6a and 33 are located at mutual distance, which means that the movements of the shower head 1 a will be formed by the sum of two pivoting movements, namely the pivoting movement of the carrier 3a around the axis 6a in rela- tion to the part 32 and the pivoting movement of the latter around the axis 33 in relation to the base part 31. Thereby the maneouver possibilities of the user also increase as to the po¬ sition of the shower head 1 a.

The pivotable part 32 has the character of a link extending from the region of the rear part of the toilet bowl in a forward direc¬ tion to approximately the intermediate region of the toilet bowl, the part 32 being located on one side of the toilet bowl.

In this embodiment the base part 31 presents a screen piece 34 which projects down into the toilet bowl in the area of the rear part of the toilet bowl. The shower head 1a can be pivoted be¬ hind this screen piece so that, accordingly, the shower head 1a obtains a position in which it is protected by the screen piece 34 also when the part 16a which forms the sitting surface and the mantle 8a connected thereto are swung up to the position according to Fig. 6.

In the embodiment according to Fig. 6 the handle 35 has a gen- erally rod-like shape, the diametrical axis of the rod-shape ex¬ tending generally horizontally. At the handle 35 a valve 9a is ar¬ ranged for regulation of the water supply to the shower head 1a. The valve could, in a simple embodiment, only permit on and off turning of the water supply, but could, in a more advanced em- bodiment, also permit flow volume regulation.

During use of the embodiment according to Fig. 6, the user can manoeuver the shower head 1a by holding the handle 35, not only by means of pivoting movement around the vertical axis 6a but also by bringing the part 32 to pivot in relation to the part 31 around the axis 33. This means that the shower head 1a is substantially moved in the forward/backward direction of the toilet seat by pivoting around the axis 6a. By pivoting the part 32 in relation to the part 31 the shower head 1a will, in the main, be movable in the cross-wise direction of the toilet bowl. The particular advantage from the freedom of motion of the shower head 1 a around two pivot axes 6a and 33 arranged at mutual distance, is that the shower head 1 a can be brought to move back and forth generally in the intermediate region of the toilet bowl in the forward/rearward direction thereof by suitable weighing of the pivoting movement compo¬ nents around each of these axes.

Of course, the invention is not just delimited to the embodi- ments having being exemplified on the drawings and described above. Accordingly, a lot of modifications of the practical em¬ bodiment can take place within the frame of the invention.
