The present invention relates to a portable sink that can be easily moved and transported from one place to another and does not need a fixed installation and therefore can be used in any place.

Currently, it is known that persons who are bedridden because of particular pathologies, surgical procedures or motor skill deficits are unable to take care of their own hygiene in an autonomous manner.

These bedridden persons, in order to meet their hygiene needs, need a person who brings a bowl that is rested on the bed and a jug that is held by another person who pours the contents thereof in the bowl to allow the bedridden persons to wash for example their hands and take care of other hygiene needs.

One drawback that is found in the background art resides first of all in that the bedridden person constantly needs help from another person during all the hygiene operations.

This background art furthermore requires the other person to empty the bowl and fill the jug several times because of the limited volume of water that can be contained in the jug and in the bowl, having then to move the bowl closer and support it near the bedridden person if the latter needs for example to wash their face, so as to prevent the water from wetting the bed.

If, in order to avoid the continuous emptying of the bowl and the continuous filling of the jug, the bedridden person reuses the water contained in the bowl, this dirty and stagnant water would carry bacteria, with a consequent negative effect on hygiene care.

The aim of the present invention is to eliminate the drawbacks mentioned above, by providing a sink that allows bedridden people to take care personally, in an autonomous, convenient and quick manner, of their own hygiene.

Within this aim, an object of the present invention is to provide a sink that allows hygiene care of the bedridden person in a condition of maximum hygiene.

Another object of the invention is to provide a sink that, when used, has a small bulk.

A further object of the invention is to provide a sink that can be easily moved and transported from one place to another and does not need a fixed installation.

Another object of the invention is to provide a sink that is structurally simple, has low production costs and can be manufactured with ordinary known systems.

This aim and these and other objects that will become better apparent hereinafter are achieved by a portable sink, characterized in that it comprises a frame, provided with at least one pair of wheels and comprising a vertical post, which is adjustable in height and with which a reservoir is detachably associated, said reservoir is provided with a substantially box-like central body from which a conical base protrudes downward, a flexible hose being associated with the lower end of said base, a plate being associated stably, below said reservoir, with said vertical post, a folding support being associated with said plate for the temporary insertion of a bowl for collecting the drain of an overlying basin, said plate having a second temporary engagement means for said collection bowl and said basin.

Further characteristics and advantages of the invention will become better apparent from the detailed description of a particular but not exclusive embodiment, illustrated by way of non-limiting example in the accompanying drawings, wherein:

With reference to the above figures, the reference numeral 1 designates a portable sink, which comprises a frame 2 that is substantially L-shaped and comprises a first horizontal arm 3a and a second vertical arm 3b.

In the embodiment shown in Figures 1 to 10, two mutually parallel distinct arms 4a, 4b are stably connected to the first horizontal arm 3a of the frame 2, each of said arms 4a, 4b being provided in a lower region on each end with a wheel 5a, 5b, 5c, 5d.

Advantageously, each one of said wheels 5a, 5b, 5c, 5d can be of the self-locking type in order to keep the portable sink 1 stationary in position when in use.

The vertical arm 3b is axially hollow so as to form internally a seat 6.

A slot 8 is defined on the first lateral surface 7 of the vertical arm 3b, proximate to the upper end thereof.

The frame 2 comprises a vertical post 9, which is associable telescopically and slidingly inside the seat 6 of the vertical arm 3b of said frame 2. The vertical post 9 has, at a second lateral surface 10, which during use is aligned with said first lateral surface 7 of the vertical arm 3b, a plurality of holes 11 which are threaded and aligned along a same vertical axis.

The frame 2 comprises a knob 12 which is provided with a threaded stem which acts in the slot 8 provided in the vertical arm 3b of the frame 2 and can be fastened at one of the holes 11 defined in said vertical post 9, in order to lock the vertical post 9 at the desired height.

The vertical post 9 is thus adjustable in height.

An arc-like partition 13 is associated with the vertical post 9 at the free upper end, is stably associated at the first front surface 14 thereof, and is provided in a lower region with a tab 15 that protrudes on the opposite side with respect to said front surface 14.

The portable sink 1 comprises a reservoir 16 having a substantially box-like central body 16a shaped complementarity to the arc-like surface of said partition 13, from which a conical base 16b protrudes downward.

The central body 16a is provided in an upper region with an opening 17.

The partition 13 and the tab 15 are adapted to allow to associate temporarily the reservoir 16 with the vertical post 9, the central body 16a resting temporarily on the tab 15.

The reservoir 16 is made of non-toxic material and has preferably a capacity of three liters.

The reservoir 16 is provided in an upper region with a handle 18, in order to facilitate its transport, which is substantially C-shaped and surmounts said opening 17.

A flexible hose 19 is associated with the lower end of the conical base 16b of the reservoir 16.

The flexible hose 19 has, at the end that is opposite the conical base 16b, a spray head 20 provided with a button 21 to allow the controlled dispensing of the liquid contained in the reservoir 16. The vertical post 9 is provided with a first engagement means 22 for the spray head 20.

In the embodiment shown in Figures 1 to 10, the first engagement means 22 is positioned at the second lateral surface 10 of the vertical post 9 in a region below the partition 13.

The portable sink 1 comprises a plate 23 with a substantially rectangular base, which is stably associated with the first front surface 14 of the vertical post 9, below the partition 13.

A folding support 24 is frontally associated with the plate 23 and thus protrudes frontally from said plate 23 and has a substantially tubular curved shape so as to form a second opening 26.

Advantageously, two reinforcement members 27a, 27b are present below the folding support 24 and means 25 a, 25b adapted to allow the rotation of said folding support 24 are associated with the end of said members that is adjacent to the plate 23.

A second temporary engagement means 28 is associated frontally with the plate 23 and is substantially L-shaped.

The second temporary engagement means 28 is constituted by a first wing 29a that protrudes frontally to the plate 23 and by a second wing 29b which protrudes at right angles to the first wing 29a in the direction of the folding support 24 and is directed upward.

The portable sink 1 comprises a collection bowl 30 which is provided with a first bottom 31 and with a first perimetric ridge 32 on which a first hole 33 is defined which has such dimensions as to allow it to be inserted inside said second temporary engagement means 28.

The collection bowl 30 has an overall height that is lower than the space between the folding support 24 and the free end of the second wing 29b of the second temporary engagement means 28.

The first bottom 31 of the collection bowl 30 has a length that is smaller than the height of the second arm 3b of the frame 2. The collection bowl 30 is made of non-toxic material.

When the portable sink 1 is in use, the collection bowl 30 is adapted to be inserted temporarily at the second opening 26 of the folding support 24 and the first perimetric ridge 32 is adapted to rest temporarily on the folding support 24.

When the portable sink 1 is not in use, the collection bowl 30 is adapted to be engaged with said second temporary engagement means 28.

The portable sink 1 comprises a basin 34 which is provided with a second perimetric ridge 35, which is substantially C-shaped and in which a second hole 36 is defined which has the same shape as the first hole 33 of the collection bowl 30 and is provided with a second bottom 37 provided with a drain hole 38.

The basin 34 is adapted to be superimposed on the collection bowl 30 and has a height that is smaller than the height of the collection bowl 30, so that the second bottom 37 is not in contact with the first bottom 32 of the collection bowl 30.

The basin 34 has a length that is slightly greater than the length of the collection bowl 30 and smaller than the height of the second arm 3 b of the frame 2.

The basin 34 is made of non-toxic material.

ft has thus been found that the invention achieves the intended aim and objects, an invention having been obtained which allows bedridden people to take care personally, in an autonomous, convenient and quick manner, of their own hygiene.

In fact, the portable sink 1 is easily brought close by or to the bedridden person by means of the wheels 5a, 5b, 5c, 5d, adjusting beforehand the height of the collection bowl 30 and of the basin 34 by means of the telescopic height adjustment of the post 9; the position can then be locked by virtue of the self-locking wheels.

Thus, the bedridden person is then capable of providing personally to their own hygiene by actuating the spray head 20 with the button 21 that allows the controlled dispensing of the liquid contained in the reservoir 16 that is collected into the collection bowl 30.

The portable sink 1 dispenses a quantity of water which is sufficient to ensure the hygiene care of the patient by virtue of the capacity of the reservoir 16.

It has been found, furthermore, that the invention allows hygiene care of the bedridden person in a condition of maximum hygiene by virtue of the fact that the reservoir 16, the collection bowl 30 and the basin 34 are made of non-toxic material, are easy to be washed and prevent the formation of bacteria in the clean water that is used for the care of the bedridden person.

In particular, the cone-like shape of the conical base 16b that protrudes below the central body 16a of the reservoir 16 avoids the stagnation and therefore the formation of bacteria in the reservoir 16.

Furthermore, the overlapping of the basin 34 on the collection bowl 30 of the drain of said basin 34 through the drain hole 38 allows to collect and separate the used water from the dispensed clean water, thus preventing the dirty and stagnant water from coming into contact with the dispensed clean water.

Finally, the reservoir 16, the collection bowl 30 and the basin 34 can be cleaned easily because they are all components that can be easily uncoupled respectively from the partition 13 and from the folding support 24; furthermore, the large upper opening 17 of the reservoir 16 allows easy cleaning thereof.

Moreover, it is noted that the invention, when not in use, is compact, as shown in Figure 10, since the vertical post 9 can be adjusted at its minimum height by virtue of the knob 12, the folding support 24 can be folded at 90° so as to be arranged along an axis that is parallel to the vertical post 9, and the collection bowl 30 and the basin 34 can be engaged to the second temporary engagement means 28 by means of the first and second holes 33, 36. Moreover, it is possible to engage a plurality of collection bowls 30 with superimposed basins 34 to the second temporary engagement means 28, providing an embodiment of the portable sink 1 , not shown, in which the first wing 29a of the second temporary engagement means 28 is as long as the first arm 3a of the frame 2.

Finally, it has been found that the invention can be easily moved and transported from one place to another and does not require a fixed installation.
