Description

The present invention relates to a disappearing shower box, able to be stowed after use, to allow a different use of the space it occupies during its use.
Nowadays, the high cost of dwellings and the high density of the population, especially in large urban centres, has led to the development of a construction industry that builds small apartments, with small spaces, and generally, at least some spaces intended to serve multiple functions. Purely by way of example, one can mention here the living room with cooking corner, or the living room furnished with a sofa-bed so it can be transformed into a bedroom at night.
In particular, the bathroom must contain sanitary fittings, the shower, the washing machine and space to hang the washed laundry to dry.
There are also dwelling structures where space is at a premium because of the very nature of the structure itself, such as ships or large leisure boats.
Returning to the aforementioned bathroom, the most common solution in general is to exploit space in the vertical as well, for instance by placing above the bath tub a laundry dryer capable of vertically sliding to be easily loaded in the lowered position and then raised upwards.
However, this advantageous arrangement cannot be used in the presence of a shower box. In this situation it is clear that exploiting the vertical space above the shower box is prevented by the presence of the frame, projecting horizontally in overhang from the wall, which supports the shower curtain and often also by the pipe feeding the shower head, also projecting in overhang from the wall.
It is also known that in small bathrooms, the shower water falls directly on the floor and is evacuated by means of a drain buried in the floor. It is also possible for water to fall onto a shower plate associated to the aforesaid booth and fastened to the floor underneath the shower head, so that the shower booth takes up a considerable amount of space when it is not in use.
The Applicant has now found that, by appropriately modifying the essential structure of a shower booth, it is possible to obtain a disappearing shower booth, i.e. one that can be substantially eliminated after use in order to allow a different use of the space it occupies during use.
The Applicant has also found a new shower plate structure whereby it is possible to obtain a disappearing shower plate, foldable after the shower booth is used, to exploit the space of the room in which the shower is installed.
The present invention aims to solve the problems noted in the prior art, proposing a disappearing shower booth whose bulk, when not in use, is smaller than its bulk when in operating conditions.
Therefore, the subject of the present invention is a disappearing shower booth as better defined in the accompanying claims.
Additional characteristics and advantages of the invention shall become more readily apparent from a preferred, but not exclusive, embodiment of a disappearing shower booth according to the present invention.
The description shall be provided below with reference to the accompanying drawing, provided purely by way of non limiting indication, in which:

Figure 7 shows a perspective view of a shower plate belonging to the shower booth of Figures 1 and 2, in operating position; and,
Figure 8 shows a plan view of the shower plate of Figure 7.

The shower booth 1 of the invention, in its more general form, comprises a support frame 2 (figures 3, 4 and 5) for a shower curtain 3, anchored to an equipped vertical wall 4 and rotating about at least a horizontal axis X parallel to said vertical wall 4, and an actuating device 5 for actuating said support frame 2. Said support frame 2 is provided with at least an anchoring element 6 for the curtain 3, is hinged about said horizontal axis X and is movable between two positions, respectively an operating position, in which the support frame 2 projects in overhang from the vertical wall 4 (Figures 1 and 3) and the curtain 3, hanging vertically downwards from the anchoring element 6, and a resting position (Figures 2 and 4), in which the support frame 2 is positioned parallel to said vertical wall 4 and the curtain 3 is folded against said the anchoring element 6. In the particular embodiment described herein, the support frame 2 comprise a rotating arm 7 hinged to at least a first bracket 8, in correspondence with a respective hinge 8a, integral with the equipped vertical wall 4, whereon the booth 1 is mounted. The arm 7 is integral with a case 9 having semi-circular shape in plan view (Figures 5 and 6), along whose edge is fastened a semi-annular section bar 10 wherefrom hangs the curtain 3.
The device 5 for actuating the support frame 2 comprises a linear actuator 11 (Figures 3 to 5) of the piston type whose cylinder 12 is hinged to at least a second bracket 13, in correspondence with a respective hinge 13a, integral with the equipped wall 4 whereon the booth 1, simplified and shown schematically in the upper portion, is mounted, and whose rod 14 is hinged on the rotating arm 7 in a position that is not aligned with the eyelets of the two brackets 8, 13. The actuator 11 can be of any known and convenient type, also taking into account that it must function in a bathroom, in the presence of water and humidity: for instance, it can have a waterproof electric motor, preferably with low voltage, which moves a cinematic coupling with lead nut and worm screw, or a piston as described above, operating with compressed air or of the hydrodynamic or oleo-dynamic type.
The present description shall not normally illustrate all possible structural and cinematic alternatives to the embodiments specifically described herein, said alternative forms being readily apparent from the description provided herein of the relationship that links each specific embodiment with the result to be obtained.
For example, both the rotating arm 7 and the linear actuator 11 can be hinged, instead of to a single bracket 8, 13, to a pair of brackets positioned, one on each side, to both sides of the arm 7 or of the actuator 11, the aim of the cinematic mechanism being substantially to move the arm 7 about the horizontal axis X, embodied by the hinge 8a of the bracket 8, for an arc of about 90°.
The brackets 8 can also be fastened directly to the equipped vertical wall 4 but they are preferably mounted on a metallic "C"-shaped or "T"-shaped or "L"-shaped section bar, walled onto the wall, to facilitate the subsequent mounting and readying of the shower booth 1 according to the invention.
In the specific embodiment described herein the case 9, which identifies the plan-view surface of the shower booth 1, has semi-circular shape but it is clear that it could even have square or rectangular shape, or any other shape, said shape being substantially irrelevant in relation to the invention.
In particular, the case 9 is preferably an open box structure comprising a semi-circular base, with the diameter positioned parallel to the equipped wall 4, and provided with an edge 15 perpendicular to said base and extending along the curvilinear profile of said base and oriented towards the shower curtain 3.
As shown in Figures 1, 2, 7 and 8, the shower booth can also comprise a shower plate 16 mounted in proximity to the vertical wall 4 of the bathroom underneath the support frame 2; in its most general form, it has preferably square o rectangular shape, although any other shape can alternatively be used, the shape being substantially irrelevant with respect to the invention. The plate 16 comprises a flat plane 17, which defines a bearing surface treaded by the shower user. The aforesaid flat plane 17 can be obtained in any known fashion, for instance by means of a sheet of suitable plastic material moulded into the desired shape. Preferably, the plane 17 comprises a peripheral edge 17a that is raised relative to the bearing surface, developed along three sides, absent along the parallel side and adjacent to the wall 4, said edge 17a has the purpose of collecting the water into the plane 17 and convey it towards the wall. The aforesaid plane 17 is mounted on a platform 18 comprising a series of flanges 19 and cross members 20, mutually integral to constitute a non deformable structure, able to support the weight of at least one person and the movements described below. At least one, but preferably at least a pair, of said flanges 19 has elongated shape and has an end that is integrally fastened to a shaft 21, constituting an axis of rotation "X" for said plane 17. Said shaft 21 is positioned horizontally, i.e. parallel to the floor, and is free to rotate within at least a bushing 22 fastened to the floor, or to the adjacent vertical wall (Figures 7 and 8). In particular, as in the case illustrated herein, the bushing 22 is secured by means of a bracket 23 fastened to the wall or to the floor in any convenient fashion, for instance with bolts 24. On the shaft 21, at least one of its ends is keyed in integral fashion a coaxial pulley 25 for actuating said platform 18. Preferably, the side of the plane 17 lacking the raised edge 17a coincides with the position of the rotating shaft 21 and, yet more preferably, the surface of the plane 17 along said side winds about the aforesaid shaft 21. A tank 26 for collecting the water of the shower 1 is provided on the vertical wall 4 adjacent to the shaft 21, in correspondence with said plane 17. The mouth for loading the tank 26 is positioned inferiorly to the bearing surface of the plane 17. In other words, the height from the ground "h" of the edge 17a of the tank 26 facing the edge 17a of the plane 17 (Figure 1) is no greater than the height from the ground "H" of the surface of the plane 17 in correspondence with the rotating shaft 21. The aforesaid tank 26 extends (Figures 7 and 8) for a length "a" no lesser, and preferably greater than the length "b" of the plane 17, whilst in terms of width (Figures 1 and 2) it extends from the wall to the adjacent edge of the plane 17, and preferably also beyond said edge. In other words, the distance "c" of the edge of the tank 26 from the wall is preferably greater than the distance "d" of the side without edge of the plane 17 from the wall 4. The tank 26 is connected with a trap 26a, positioned between the tank 26 and the floor, for evacuating the water. Preferably, the side of the tank 26 in contact with the wall of the space extends for a considerable height along the aforesaid wall in order to collect and convey to the drain the water splashes which, otherwise, would inevitably end on the wall itself, in the long run ruining the plaster and permeating the wall with humidity. Preferably, the surface of the plane 17 is slightly inclined towards the edge facing the tank 26 to facilitate the drainage of the water. Preferably, at least one of the aforesaid flanges 19 is provided with a foot 27, hinged to the flange, with the centre of gravity positioned between the hinge point and the floor. Consequently, the foot 27 is always oriented vertically; it serves as a support for the platform 18 when the shower plate 16 is in use (Figures 1 and 7) whilst it aligns with the flange 19 when the shower plate 16 is in folded position (Figure 2). As a result, the bulk of the folded shower plate 16 is the one substantially determined by the thickness "s" of the plane 17 (Figure 2) mounted on the platform 18, smaller than the height "T" (Figure 1) of the aforesaid edge 17a from the ground, and hence it has very small dimensions.
Preferably, the surface of the platform 18 oriented towards the floor (when the shower plate is in use) is coated with a panel 28, for example made of the same material as the shower plate 16, for substantially aesthetic reasons in order to conceal the frame of the platform 18 when the shower plate 16 is folded (Figure 2) against the wall 4. Preferably, at least at one of the ends of the rotating shaft 21 is positioned a case 29 (Figure 8) which encloses at least the pulley 25 and, at least in part, means 30 for operating the pulley 25 to actuate the shower plate 16.
The operation of the shower booth 1 according to the invention is now easily understood: in the closed position (Figures 2 and 4) the rotating arm 7 hangs downwards from the hinge 8a of the bracket 8; the case 9 fastened to the arm 7 hangs therewith, being set down on the vertical wall 4, and hides from view the shower curtain 3, folded in bellows fashion against the semi-annular section bar 10, the actuator 11 for the actuation of the arm 7 and the other devices described hereafter.
The bulk of the support frame 2 of the folded shower booth 1 is the one substantially determined by the thickness of the case 9, i.e. by the height of the aforesaid edge 15, and therefore it does not constitute a substantial hindrance to the use of the space occupied by the shower booth 1 in operation.
Preferably, the shower booth 1 according to the invention comprises additional devices able to facilitate and rationalise the operation of the shower booth itself.
In the first place, it comprises a cinematic mechanism 31 to actuate the shower booth 3 alternatively between an open position and a closed position.
It has been noted that when the shower booth 1 is in use the shower curtain 3, hanging from said at least one anchoring element 6, is deployed vertically downwards. In a preferred embodiment, the anchoring element 6 is a semi-annular section bar that runs along the curvilinear profile of the case 9, preferably inside the edge 15 of the case 9, thereby remaining hidden from the view of an external observer.
The curtain 3 is anchored to said section bar 6 with any known and convenient means, for instance a series of hooks, and in open position it hangs vertically downwards.
The curtain 3 can be constituted by a single sheet, as in the illustrated version, or by multiple distinct sheets; the latter solution is the most convenient when the section bar 6, instead of semi-annular, is constituted by a series of rectilinear section bars arranged mutually angled, for example as advantageously provided with the case 9 has rectangular, square or trapezoid shape.
In any case, the lower edge of the curtain 3 is preferably ballasted with suitable means, for instance a series of heavy elements anchored to the aforesaid lower edge 3a, to keep the curtain 3 taut. In the preferred embodiment described herein, the aforesaid suitable means include a continuous semi-annular bar 32 (Figure 3) whose profile is identical to that of the section bar 6, anchored to the lower edge 3a of the curtain 3.
The bar 32 is connected to a plurality of flexible tie rods 33, preferably at least three, for instance textile or metallic wires or strings, preferably made of nylon®, fastened to the bar 32 at least at the end thereof and at least in an intermediate position. At the other end, tie rods 33 are connected to a pulley 34 mounted on the case 9, and more preferably on the rotating arm 7, and along their development they are partially wound each about at least an idle transmission roller 35 (Figures 3 and 4), mounted along the peripheral edge of the case 9 in correspondence with the annular section bar 6.
In the segment between the section bar 6 and the bar 32 the tie rods 33 are connected, in freely sliding fashion, to the curtain 3, for instance by means of a plurality of rings fastened to the curtain 3 and through which slide the aforesaid tie rods 33.
The pulley 34 could be commanded manually, but it is preferably motorised: in accordance with the preferred embodiment illustrated herein, the motorisation comprises a first gearwheel 36 integral and coaxial with the pulley 34, connected by means of a positive drive transmission belt 37 to a second gearwheel 38, preferably also mounted on the rotating arm 7 and driven by a motor (not shown herein) of any known and convenient type. The aim of the cinematic mechanism 31 described herein, which sees numberless possible embodiment variations, is to set in rotation, on command, the wire winding pulley 34. The operation is readily apparent: the pulley 34 is actuated in rotation, alternatively in the two directions, respectively to spread the shower curtain 3 when the shower booth 1 is placed in the operating condition and to wind the shower curtain 3 after the booth 1 is used. When the curtain 3 is retrieved, the tie rods 33 are wound on the pulley 34 sliding on the idle transmission roller 35 and raising the semi-annular bar 32 upwards. The shower curtain 3, fastened to the tie rods 33, is forced to fold in bellow fashion against the section bar 6. The motion stops when the bar 32 arrives in correspondence with the section bar 6 with the curtain 3 completely folded on itself and positioned between section bar 6 and bar 32. The same movement in the opposite direction causes the deployment in the vertical direction of the curtain 3, initially folded on itself.
The support frame 2 also has a shower head 39 which, in a preferred embodiment of the device of the invention, is fastened to the case 9, or preferably to the rotating arm 7, at the end of a segment of rigid pipe 40 also integral with the rotating arm 7 or with the case 9. In any case, the other end of said rigid pipe 40 is connected to the water feeding outlet, not shown, with a flexible connection element, not shown herein, which can also replace the rigid pipe 40. Alternatively, the device of the invention can comprise only a means for latching said shower head 39 which, when the booth 1 is open, is hung from the rotating arm 7 whilst, when the booth 1 is closed, it remains hanging from the vertical wall 4, in wholly known fashion and always connected to the water outlet with a flexible connection element.
The base surface of the case 9 can be a continuous surface or have an opening in correspondence with the rotating arm 7 to allow mounting the aforesaid devices, i.e. gearwheels 36, 38, transmission belt 37, motorisations, shower head 39; in this case, the desire to hide the aforesaid devices from view, with the shower booth 1 closed, can entail the need to build the base of the case 9 with two mutually parallel but not coplanar surface portions, a peripheral one and a central one, placed in correspondence with the aforesaid rotating arm 7, the latter projecting from the peripheral portion, closer to the vertical wall 4 with the booth 1 closed.
Preferably, the surface of the case 9 exposed to view, i.e. the one opposite to the vertical wall 4 is covered with a mirror 41 in order to provide greater luminosity and greater virtual depth to the space, as well as a touch of elegance and refinement to the device of the invention.
Based on the above description, the operation of the shower plate 16 of the invention is also readily apparent. By alternatively acting in both directions on the pulley 25, the shower plate 16 is caused to rotate about the shaft 21, thereby moving the shower plate 16 alternatively between the operating position, horizontal shower plate 16, plane 17 substantially parallel to the floor, and the resting position, shower plate 16 folded against the vertical wall 4 of the bathroom. Note that in this position as well (Figure 2) the water that drains from the shower plate 16, continues to flow into the collecting tank 26 and is not dispersed on the bathroom floor.
The operation of the pulley 25 can be obtained in any convenient fashion, known to those versed in the art. In particular, when the shower plate 16 is used alone, in the absence of the aforementioned booth, as means 39 for actuating the plate 1 can be used a motor that directly commands the pulley 25, or a suitable cinematic mechanism, for instance with gearwheels and transmission pinions, for connecting the pulley 25 with a motor positioned at a distance from the pulley itself.
Additionally, the rotation of the shower plate 16 can be obtained by means of different actuators from those described above, for instance by a system of arms or levers that directly connect the plate 16 to the vertical wall or to the floor, without the presence of the pulley 25.
Preferably, the shower plate 16 of the invention is used in combination with the disappearing support frame 2.
In this embodiment, preferably, the support frame 2 and the shower plate 16 do not move independently from each other but are mutually connected. In particular, the pulley 25 of the shower plate 16 is controlled by the motor that commands the actuation of the frame 2 by means of a transmission system, such as by "V" belts or positive drive belts, chains, ropes or other means. Alternatively, a lever system directly connects the frame 2 of the shower booth 1 with the plate 16 with no need for the pulley 25. In general, the system connects the means 30 for actuating the plate 16 with the device 5 for actuating the frame 2 in such a way as to achieve synchronism between the movements of the frame 2 and of the plate 16. In other words, when the booth 1 opens, the frame 2 and the platform 18 of the plate 16 simultaneously move to the horizontal position, the shower plate 16 at the level of the floor, the frame 2 of the booth 1 in elevated position, overlying the shower plate 16. Thereupon the curtain 3 is deployed in height by being lowered from the frame 2 down to the level of the plate 16, thereby creating an environment insulated from the space that contains the booth 1.
In this embodiment, preferably, the connection system between frame 2 and plate 16 is contained within an upright 42, fastened to the wall 4, which hides and protects the elements of the system. Said upright 42 can advantageously constitute also the support element for the means for actuating the frame 2 and the shower plate 16.
Figures 1 and 2 show this preferred embodiment of the invention. Figure 1 shows the disappearing shower booth 1 when opened, in the operating position from the frame 2 of the booth 1, projecting in overhang from the vertical wall of the space, hangs downwards the shower curtain 3 fully deployed over its entire height. Preferably, the lower edge 3a of the curtain 3 remains within the peripheral edge 17a of the plate 17 in such a way as to prevent water from spraying onto the floor.
When the booth 1 is closed, at first the curtain 3 is folded in bellows fashion upwards, against the frame 2 of the booth 1, then the frame 2 of the booth 1 and the platform 18 of the shower plate 16 are simultaneously brought to the vertical position and folded against the wall. Figure 2 shows the disappearing shower booth 1 in folded, closed position. The frame 2 and the platform 18 are positioned vertically along the wall 4, and preferably oriented towards each other. Note that, alternatively, having a sufficiently high wall 4 available, the frame 2 could be rotated in the same direction as the shower plate 16 and hence folded upwards.
Moreover, if the shower booth 1, with its plate 16, is installed in correspondence with a corner of the bathroom, the shower plate 16 and the frame 2 of the booth 1 can be folded each against a different wall of the corner, the frame 2 against a first wall, the plate 16 against the adjacent wall.
The invention achieves important advantages.
It should first of all be noted that the shower plate of the invention, when closed, allows an alternative use of the space it occupies during use, in such a way as to allow a continuous use of said space. The bulk of the aforesaid plate in the folded position is minimal and does not constitute a substantial sacrifice of space in regard to the aforesaid alternative uses.
Lastly, in the closed position, the shower plate according to the invention is aesthetically pleasing.
It should also be noted that the support frame of the shower booth according to the invention allows to exploit the otherwise unused space, also in the case of bathrooms without shower plate but provided only with a drain flush with the floor.
In addition, the support frame without the plate can easily be applied above the bath tub and opened only in case of need, making otherwise available the space above the bath tub itself for the placement, for instance, of a laundry dryer.
