Description

MOBILE BED DESCRIPTION

The present invention relates to a mobile bed. A plurality of beds, or other structures destined at allowing people to lie down for resting or sleeping, is known .

Usually the utilized beds are formed by a generally sufficiently soft, however comfortable plane support, rested onto the ground by means of specific supports, or in case, as it happens, for example, for the futon, the bed used in Japan, directly rested onto the ground.

Clearly, in these cases, the user's position is fixed with respect to the ground and, in other words, the plain, surface whereon one sleeps is however integral to the ground.

Beside such traditional solutions there are beds which utilize a plurality of devices to make sleep more comfortable .

In particular, vibrating beds are known, wherein the user is massaged and relaxed before and during sleep.

However, it must be pointed out that such products create situations which, especially if utilized for long intervals, can be too repetitive and monotonous.

Another known solution to improve the bed's comfort, but above all for therapeutical reasons, is the one which provides the use of a base whereon the bed is rested, which is partially reclining so as to lift head or foot.

However, they are always basically static beds, since the user's position during sleep substantially remains integral to the groμnd.

Apart from beds, furthermore there are other kinds of structures destined at laying down thereon, which are alternative thereto, and provide still different sensations of comfort and relax. An example of such structures is constituted by the hammocks which, even though they are not particularly comfortable for sleep, they succeed in relaxing the user thanks to the swinging possibility.

Besides, such movement is analogous to the one of cradles, which can swing so as to favour the child's sleep.

In any case, however, even such motions are substantially repetitive and constant.

Consequently, generally the need is felt for utilizing not only ever more comfortable beds, but however innovative and alternative beds with respect to what implemented according to known art.

Therefore, the technical problem underlying the present invention consists in providing a bed allowing to obviate to the drawbacks mentioned with reference to the known art.

Such problem is solved by a mobile bed according to claim 1.

The main advantage consists in that the mobile bed according to the present invention allows a very comfortable rest and a high degree of relax during use, in a different and alternative way with respect to the existing products, with the feature of being able to make the motions variable.

Other advantages, features and application modes of the present invention will be evident from the following detailed description of some embodiments, shown by way of example and not for limitative purposes.

The figures of the enclosed drawings will¹ be ^■ referred to, wherein: figure 1 is a perspective, partially sectional view of a first embodiment of the mobile bed according to the present invention; figure 2 is a schematic illustration showing the motions of the bed of figure 1 obtained by means of the combination of rotations around two different axes; figure 3 is a schematic illustration showing the operating principle of connecting and supporting means of the mobile bed according to a second embodiment ; figure 4A is a perspective, partially sectional view of the bed according to the present invention in the embodiment of figure 3; figure 4B is a perspective view illustrating the connection between a piston and a frame, details of figure 4A; figure 5 is a bottom perspective view of the mobile bed according to a third embodiment; figure 6 is a front view of the bed of figure 5 schematically illustrating the operation thereof; figure 7 is a perspective, partially sectional view of a fourth embodiment of the bed according to the present invention; figure 8 is a front sectional view of the bed of figure 7 schematically illustrating the operation thereof.

By firstly referring to figure 1, a bed 100 according to the present invention comprises a resting surface 1, destined at housing the user in the lying position. Clearly, in accordance to the beds implemented according to the known art, the resting surface 1 can be implemented with an elastic bed base 11, for example implemented by means of springs or wood slats, whereon a mattress 12 is placed. The base can be then rigid, thus substantially extending plain or it can have reclining portions in order to keep head or legs lifted, similarly to the already known beds.

The bed according to the present embodiment has supporting means 2 of the z^~ebting surface 1 so as to allow the support thereof above the ground.

Such supporting means 2, then, keeps the surface whereon the user lays down lifted from the ground, both for hygienical purposes, by avoiding that dust or other dirt accumulate in the area wherein one rests, and, as it will be described in detail later, in order to allow the motion of the resting surface 1 with respect to the ground itself. •

In particular, then, the bed comprises specific connecting means 3 between the resting surface 1 and the supporting means 2. Such connecting means not only guarantees the connection between the members mentioned above, but they also allow the resting surface 1 to perform relative motions with respect to the supporting means 2 and, then, also with respect to the ground. Incidentally, the applicant has observed that, during rest, the motion of the resting surface 1 has particularly relaxing effects, thus improving the quality of the sleep itself and the general comfort.

However, to this purpose, simple vibrating or swinging motions are not sufficient, but an undulatory combined motion is desirable which, by way of example, can remind the one of a boat at anchor moved by the sea's waves, in calm waters, such as those of a roadstead, a harbour or a however sheltered cove. Therefore, still by referring to figure 1, according to a first embodiment of the present invention, the connecting means is apt to allow rotating motions of the resting surface 1 around at least two different rotation axes 41, 42. As it will be seen in details hereinafter, the motions which are thus implemented derive from the combination of the rotation around the axes mentioned above and, consequently, they could produce also motions around axes different from the illustrated ones. By referring to figure 2, the motions can be combined so as to create a rotation of the resting surface 1 around a point 44. In particular, in the present figure, the resting surface 1 is represented in its balanced configuration, in other words parallel to the ground, by means of a dash-dot line, after a first rotation around the axis 42 with a single broken line and, at last, with a continuous line in a configuration obtained by means of the combination of the preceding rotation with the one around the axis 41.

The axes 41 and 42 are arranged substantially orthogonal therebetween, by keeping such mutual position during the movement .

Furthermore, in the present embodiment, the surface 1 has a substantially symmetrical shape and the axes 41 and 42 coincide with the symmetry ones of the surface. Such feature advantageously allows a better distribution of the masses during the motion of the resting surface and, clearly, symmetry in the motions themselves .

The symmetrical motions, in particular, can result to be more pleasant when the user is laid down substantially at the bed's central area.

By referring again to figure 1, in the present embodiment, the resting surface 1 has a substantially rectangular shape, being the base 11 and the mattress 12 basically analogous to the ones utilized for usual beds.

In analogy with what shown previously, the axes 41 and 42 correspond to the symmetry axes of the rectangle and they are parallel to the sides of the same.

In the present embodiment the connecting means 3 comprises first pins 31, arranged on opposite sides of the resting surface 1, which allow the rotation of the same with respect to a first axis 41.

The joint is fastened to a cross-like support 33, which has respective first ends 34, connected to first pins 31, and second ends 35, connected to additional pins 32.

These latter pins 32 implement a pivoting connection between the cross-like support 33 and the supporting means 2, which 'as already said keep the resting surface lifted from the ground.

In the present embodiment the supporting means 2 is implemented by means of two supports 20, shaped like a rod, sufficiently resistant and stable as to sustain the

-bed during the motions of the surface 1 or, in case, by means of stands, which make the bed even more stable.

The cross-like support 33 is shaped so that the pins 32 are arranged at the second symmetry axis so as to implement the rotation around the axis 42.

In this way, the motions with respect to the two axes 41 and 42 are independent therebetween and they can be freely combined so as to allow in practice the rotation of the resting surface around a point, defined, in particular, by the intersection of the axes 41 and 42. In order to implement such function, the cross-like support can be conveniently implemented by two rod-like members 36, with a curved shape, which, at least in the present embodiment, extend above the resting surface 1. It is clear that upon implementing such feature the user's comfort must be considered, in other words the rod-like members and the cross-like support must not create any trouble to the user. However, the just-described solution can be replaced by a similar implementation wherein the cross-like support is placed under the resting surface, with identical functional features.

Furthermore, the rod-like members 36 are connected to the respective central portions so as to connect the ends 34 and 35 and to allow the surface 1 to rotate around the axes mentioned above.

Such shape has also the advantage of conferring to the bed a peculiar aspect so as to make it remarkably original and characteristic.

Alternatively, the rod-like members can be arranged below the surface 1, in particular by providing an extension sufficient to the ends 34 and 35 and rectilinear rod-like member so as to limit the overall sizes, but not to obstruct the motions of the resting surface . It must be then understood that the required motions are rotations around contained angles, indicatively max. 15-20 degrees and above all with modest speeds and accelerations. Furthermore, the motions can take place with variable speeds and accelerations, depending upon the wished motion features.

In each case, for the user more rapid motions and for wide angles will not be pleasant since they would disturb sleep.

Without describing in details the features of the implemented motions for the time being, the motion can be simply entrusted to electric motors 37, connected to the pins.

In particular, motors with modest power will be sufficient, in case coupled with geared motors or variators, exactly for the small shifts which are required.

It is also clear that the supporting means 2 can be adjusted in height so as to allow also vertical motions of the resting surface 1. Such feature can be also advantageous to ease to the user to go up and down the bed, since it could be convenient that this is positioned at a height so as to allow the rotations of the surface 1.

However, such motions are independent from the rotations mentioned above and therefore they can be freely combined therebetween.

Furthermore, the bed according to the present invention comprises a control electronics handling the motors' motion and, consequently, also the position of the resting surface.

To this purpose, also position, speed and acceleration sensors are provided, preferably arranged near the pins and connected to the control electronics mentioned above.

In this way the position of the resting surface could be controlled in a precise way, which position under a condition, which hereinafter will be defined as rest condition, will be substantially parallel to the ground and, still with the aid of the sensors mentioned above, a series of predefined sequential and combined motions could be implemented. The control electronics in case can be connected to a PC so as to create, plan and in case simulate such motion sequences and combinations.

Furthermore it will be understood that the bed according to the present invention is subject to several changes and variants of embodiments alternative to the ones described sofar, some thereof are briefly illustrated hereinafter by referring to the only aspects which differentiate them from the embodiments considered sofar. By now referring to figure 3, according to a second embodiment, the connecting means 3 can allow the motions around axes 41 and 42 mobile in space.

It is to be noted, in fact, that in the previous embodiment, the axes 41 and 42 were kept fixed with respect to the resting surface which, consequently, rotates around the intersection thereof.

In this second embodiment the supporting means 2 is implemented by means of hydraulic pistons 21 respectively fastened to the ground and the connecting means 3 is implemented by a frame 38, connected to the resting surface 1, which in substance implements the connecting means mentioned above.

In case of rectangular shape, the pistons 21 are hinged to the frame at the average point of the sides. Furthermore, since the pistons mentioned above are apt to implement the inclination of the surface 1, by assuming a first piston firmly fastened to the ground, the one on the opposite side will be connected to a guide 22 so as to allow to the pistons 21 to approach therebetween to allow the rotation of the surface 1.

Therefore, since the pistons can be moved independently, the axis thereabout the rotations take place can be positioned in a different manner.

By way of example, the same inclination of a certain angle of the surface could be implemented by means of the rotation around different axes, by using alternatively one of the two pistons or by combining the action thereof .

In this way the use of two hydraulic pistons 21, or clearly of other analogous linear actuators, arranged on opposite sides of the resting surface 1, becomes particularly advantageous upon implementing the wished motions .

The pistons could be arranged perpendicularly to the ground so as to limit the overall sizes with respect to an inclined position and in this way to allow also the support's motion in vertical direction, by making the pistons to operate at the same time.

Also in this case, since wide motions are not necessary, modest strokes of the pistons are sufficient.

Furthermore, the use of a hydraulic system is also advantageous to obtain more damped and fluid motions, a particular important feature so that the motions do not cause trouble during sleep .

Still by referring to the present embodiment, the hydraulic pistons 21 are connected to the resting surface 1 at the above-mentioned frame 38 by means of spherical joints, not illustrated in figure.

The frame can be simply implemented by means of elastic base whereon the mattress is rested.

The use of spherical joints, in particular, allows the combined motion around perpendicular axes, which is obtained by using two pairs of pistons arranged along the four sides of the resting surface. Apart from the spherical joints, in order to allow the combination of the rotating motions, also in this embodiment the bed comprises a control electronics allowing to handle the motion of the pistons or of different actuators in an appropriate way.

In fact, since fixed rotation axes are not present, the motions of a pair of pistons require also a motion of the second pair, unless the rotation does not take place around the axis passing through the latter. In order to carry out such shift, the pistons can be controlled by following mechanics of the motion the resting surface.

Thus the wished trajectory of the surface 1 can be calculated analytically before setting the pistons' motion, by intervening, if necessary, on all four of them.

Alternatively, the surface 1 can be equipped with sensors sending signals to the control means so as to make the position of two pistons to adapt to the motion of the other two pistons.

In case these motion control solutions are adopted, not preferred embodiments since they are more complex upon implementation, the connecting means can be implemented by four pistons connected to the respective tops of the resting surface and to the ground by means of spherical joints.

In fact, in this case, the solution would be mechanically stable and the pistons' motion control could guarantee the combined motions described previously. In this case, it is convenient that the pistons are inclined with respect to the ground to guarantee better stability, in particular so that the pistons' ends fastened to the ground be encompassed in a lower extension zone with respect to those fastened to the resting surface.

Nevertheless, such embodiment solution is less preferred due to the complexity in handling the motion control .

On the contrary, the use of the connecting means described previously with a fixed piston and the coupled one fastened to a guide, allows obtaining an isostatic system wherein, then, the motion of one single piston, or in case a synchronous motion of the two coupled ones, produce a motion according to a single degree of freedom, the chosen rotation axis, guaranteeing the stability of the system. In this case, then, by referring in particular to figures 4A and 4B, for the combination of the rotations, a cross-like mechanism similar to what described in the first embodiment can be provided.

For example, still according to a preferred embodiment, in this case a single pair of pistons implements the connection between the ground and the frame, thereto the resting surface is connected by means of the second pair of pistons.

Furthermore, in this case the use of the spherical joints does not even reveal to be necessary, since the motions, for the implementation itself of the connecting means, are fully independent.

Furthermore, with respect to the previous solutions, the present embodiment even allows smaller overall sizes. Furthermore, two pairs of pistons for each side can be utilized, for a total of four pairs of pistons, as in the case illustrated in figure.

In this case, even though the equilibrium was reached also in the preceding case, the connecting joints between pistons and frame or resting surface are less stressed, as they must sustain only normal or bending stress, without having to resist also to torsion.

Furthermore, pistons with lower stroke will be sufficient . The just described embodiment solution reveals advantageous since it allows the most complete freedom in motions, thanks to the combined rotations around not fixed axes.

This feature is particularly convenient in case of wide resting surfaces, for example for two people, since it allows tilting the surface 1 while keeping a limited excursion alternatively in one of the bed's sides.

Furthermore, such feature reveals to be pleasant also when a single user is present. In fact, the resting surface can provide pressure sensors which detect the body presence so that, even if the inclination variations are kept constant, the excursion thereto the user is subjected could be adjusted.

According to a third embodiment, illustrated in figures 5 and 6, the supporting means and the connecting means are both implemented by means of balls 23, whereon a curved portion 13 of the surface 1 can slide.

The balls 23 are mounted on the supports 20, which similarly to the previous embodiments, allow to keep the surface 1 lifted from the ground.

Furthermore, in this case, the supports are shaped like a rod, at one end thereof the balls are housed by means of bearings .

Furthermore, the supports 20, existing in number equal to four, allow the rest of the curved portion and, in absence of outer stresses, keep the supporting surface in equilibrium, in a position substantially parallel to the ground.

Following an outer action, the plane support can slide on the balls, following a trajectory which is produced by the bending shape of the curved portion. Then, it is evident that the supports will have to be positioned with a distance therebetween so as to allow an adequate resting zone, depending upon the bending of the curved portion.

In particular, greater bendings will require a smaller distance between the supports .

As already mentioned, the kind and/or the bending degree of the curved portion is important to allow the wished motions.-

In fact, according to the present embodiment, the curved portion can rotate, by sliding on the supports, around two rotation axes, having a shape like the arch of a circle along both axes, but with different radii depending upon the bending degree .

Such feature allows containing the excursion of the surface 1 during the rotation, since a smaller arch is covered upon decreasing the bending radius, the rotation's width being equal.

Therefore, in particular along the bed's cross direction a curved profile with reduced bending radius with respect ' to the longitudinal direction is conveniently used, since the extension of the ^• latter is much smaller than the previous one, especially in case of single beds.

In this way, the rotation angle being equal, the shifts' width in cross direction will be more contained with respect to the longitudinal one, with a reduction of the requested overall dimensions .

The shape of the curved portion can also be different from the just-described one: in particular, it is not necessary that it has a circular bending, but it can also follow other curve kinds. Nevertheless, in this case combining the motions with respect to the axes could be not easy as well or, in some cases impossible, and consequently the same results provided by the solution with circular bending could not be obtained. Furthermore, very often the implementation of kinematics of such curves could require complex calculations, even though within the reach of a skilled in the art, and therefore such solution is not advised due to the implementing difficulties. According to a fourth embodiment, described in figures 6 and 7, the curved portion 13 is defined by a spherical cap, so as to allow not only the rotation of the surface 1 around the axes 41 and 42, but the rotation around a third axis 43.

The so-implemented motion translates into the possibility of rotating with respect to a point 44, the position in space thereof is defined by the crossing of the axes 41, 42 and 43.

Such motion capability is particularly advantageous since it allows, with however simple connecting means, to obtain any possible inclination of the surface 1. On the other hand, as already shown, the mobile bed according to the present invention does not provide rectilinear motions, but, on the contrary, variable angular swings of the resting surface 1 with respect to the ground. In particular, then, the swings can be implemented by means of rotations and, in this case, the rotation axes are arranged at the user's body, so as to limit the width of the shifts thereto he/she is subjected during the bed motion. In these latter embodiments the rotation axes, even though they are respectively aligned with the user's body, and parallel to the same, they are arranged so that the intersection thereof coincides with the rotation centre of the curved portion and above the user's body. Therefore, in order to avoid the excessive excursions mentioned above, it will be advisable to keep the bending radii as biggest as possible, in line with the bed sizes.

For this reason, the use of a curved portion shaped like a spherical cap is suitable particularly in case of a double bed or however for a particularly wide resting surface .

In this case, the resting surface could have a rectangular shape as in the previous cases, or a circular shape, considering the capability of being able to move around anyone of the axes 41, 42, 43.

As far as the motion means of the resting surface 1 in case of ball supports is concerned, therefore for both the latter two embodiments, it is meant that on one side such supporting means allows a great mobility, on the other side the complexity in adjusting the motion thereof increases.

Also in this case hydraulic pistons can be used to move the resting surface, nevertheless, in order to allow the combination of the rotations, such pistons are connected both to the ground and to the resting surface, in case by means of the frame mentioned-above, with spherical joints. The use of spherical joints is linked to the fact that the rotation axes do not pass through the connection point between surface 1 and pistons, since the rotation centre is placed in an upper position, as previously explained.

According to a preferred embodiment, the pistons act independently and whereas one piston exerts a pushing or pulling action, the other ones are not under pressure, so that they could adapt their excursion for the new position.

This solution is suitable also in case the curved portion has a spherical shape, due to the possibility of rotating around a third axis 43.

Nevertheless, in this case, using the pistons without a fixed connection to the supporting surface could be possible.

In fact, the sustaining action is implemented by the supports, without requesting any connection to the pistons. Therefore it is possible utilizing the pistons so as to provide a pushing action without an existing fixed connection, but simply by approaching the piston stem and by pushing the resting surface.

To this purpose it is advisable that the piston stem acts onto the curved portion and it is equipped with a head so as to dampen the impact with the latter and at the same time so as not to create an excessive friction during the surface motion. In this case, the pistons, in fact, keep substantially parallel to the ground and come in contact with the curved portion with a certain incidence angle.

Once ended the wished pushing action, the pistons

5 retract and the resting surface tends to return in the equilibrium position, in substance parallel to the ground, by the gravity action or, in case, with the push help, implemented in the just described manner, exerted by the piston arranged in diametrically opposed position.

10 Once the surface has returned in the equilibrium position or, however, once ended a piston action, the other pistons could act so as to implement other rotations .

The pistons can then act in combined way, so as to 15 obtain a whole desired range of motions.

Furthermore, according to a preferred embodiment the pistons have contact sensors allowing to keep the stem end always in contact with the spherical portion during all motions of the resting surface.

20 In this way the motions will be accompanied, therefore consequently they will be more fluid and possible strokes of the piston stem against the curved portion will be avoided.

Still by referring to figure 7, the supports can be

25 fastened on a ring 24 mobile around the axis 43 allowing, in this way, to implement in a simple manner, and above all to control, the rotations around the axis mentioned above .

Alternatively to the use of the pistons, the motion

30 of the resting surface can be generated by means of cord members, not illustrated in figure, implementing a pulling action instead of the push action implemented by the previous actuators .

This constructive solution reveals to be

"** particularly siraplc since, by using sufficiently flexible cord members, the motions mentioned above could be implemented without particular implementing difficulties. Following the pulling action, the cord member is released and the resting surface, through the gravity action, returns to its equilibrium position. In this way it is possible' reproducing, in a quite faithful way, the action of the waves on a boat.

As far as the modes for controlling the motions according to anyone of the preceding embodiments are concerned, as already mentioned the bed according to the present invention comprises an electronics for handling and controlling the actuators, which may be electric, like the motors utilized in the first embodiment or to move the cord members, or hydraulic, like the pistons.

Nevertheless, in order to reproduce the wished motions, which as already mentioned recall the motion of a boat, under precise conditions of the sea, a programmable system is conveniently used allowing to set a predefined series of motions.

In this case the motions, under the wished conditions, of a boat equipped with motion, speed and acceleration sensors could be conveniently acquired and therefore such motions could be simulated by means of the bed's actuators.

In particular, the control electronics provides to this purpose the possibility of storing different possible motion combinations, each one associated to a respective condition of the sea.

The sequence of the implemented motions can also be detected by means of specific studies, by experimentally detecting those shifts which make sleep more pleasant based upon, for example, the duration of the REM phases in relation to other sleep stages or upon the regularity of the breath during rest .

The user can then choose, among the stored settings, the wished one by means of a specific remote control, not illustrated in figure, which furthermore allows programming the motion for a limited time period.

To this purpose the bed comprises a timer, so as to utilize the bed's motions only during a limited part of the sleep.

Alternatively to the use of pre-set programmes for adjusting the motion, also casual motions can be used,

5 even though providing a series of control parameters, so as to avoid excessive angular excursions or troublesome acceleration during sleep.

To this purpose the law governing the motion could evolve in a casual way at first, but some weights could 10 be provided in the subsequent variations so as to reduce the risk of unpleasant motions to the maximum.

By way of example, by assuming that the motion starts with a rotation around an axis, the use of weights upon producing the motion would involve that at time of 15 the subsequent shift, even though it is produced in a casual way, the motion around the same axis has a lower possibility than the other motions.

As mentioned, in order to simulate and display the possible motion programmes or in case to create new ones

20 thereof, the bed according to the present invention comprises means for connecting to a personal computer, so as to handle such functionality also graphically.

Furthermore, still in order to have the maximum comfort during sleep, means for reproducing sounds could 25 be provided, in particular to stimulate the sea's rumour too, as well as pleasant sounds and voices.

At last, it is to be noted that the first embodiment is particularly suitable for fastening additional fittings such as tanning lamps or ventilation systems. 30 The present invention has been sofar described by referring to preferred embodiments . It is to be meant that other embodiments can exist belonging to the same invention core, all comprised in the protection scope of the claims illustrated hereinafter.
