There are known beds with a bed base that can be lifted to access a compartment under the same.
In turn, the bed base can also support one or more containers that in this way are made easily accessible.
Beds with liftable bed bases of a known type are generally produced by means of complicated lever mechanisms comprising springs that facilitate lifting of the bed base.
Bed base lifting systems of a known type generally have the drawback of being bulky and heavy, due to the fact that they are made of iron to withstand the considerable forces required for their operation.
A further drawback of devices of a known type consists in the fact that with the existing kinematic mechanisms a considerable amount of starting energy is required for opening the bed and, during closing, a considerable amount of holding energy is required to avoid collapse, to the disadvantage of safety.
A further drawback of known systems is that, once again due to the structure of the kinematic mechanism, gas springs with high forces must be used, subjecting the kinematic mechanism to considerable stress.
Another drawback of known devices is that the operations for assembling and disassembling the kinematic mechanisms are laborious and slow.
A further drawback of known systems is that due to the functional limits of the kinematic mechanisms, the gas spring must be changed when the load varies.
A further drawback of known systems is that, in the event of a sudden excessive load during closing, the bed base accelerates and collapses on the container of the bed, to the disadvantage of safety.

A further object of the invention is to provide a bed structure with openable bed base that can be made of light materials, even not metallic, such as wood for the bed base and plastic for the components of the articulation device.
Another object of the invention is to provide a bed structure with openable bed base provided with an articulation device of a limited size so as to be almost invisible and that can be arranged completely within the volume of the container of the bed.
A further object of the invention is that to provide a bed structure with openable bed base that allows extremely easy and rapid assembly of the bed base with the bed without requiring tools, so as to allow a saving of time and therefore of costs, and easy and rapid assembly and disassembly, both for cleaning and for any movement required.
Another object of the invention is to provide a bed structure with openable bed base provided with an articulation device that, due to its characteristics, allows a considerable applicable load range, using the same gas springs.

DESCRIPTION OF PREFERRED EMBODIMENTS With particular reference to the numerical symbols of the aforesaid figures, the bed structure with openable bed base, according to the invention, generally indicated with the reference numeral 1 , comprises a bed base 2 articulated to the sides 3 of a bed 4 via a pair of articulation devices 5.
In the figures, and in the following description, only one of the sides of the bed 4 and related articulation device 5 will be shown.
According to the present invention, the articulation device 5 comprises guide means of the lifting movement of the bed base 2, locking means of the bed base 2 in an open position, and means of elastic support adapted to assist the lifting and lowering movement of the bed base 2.
The articulation device 5 comprises a small frame 6 fixed to the side 3 of the bed and provided with a curved guide 7 in which two wheels 8 and 9 slide, integral with a plate 10 fixed to the bed base 2.
The curved guide 7 is configured so that the bed base 2 undergoes a swivelling opening movement, from a closed position, visible in Figs. 1 and 2, to an open or raised position, visible in Figs. 3-6.
The movement of the bed base 2 is lockable in an open position via a ratchet device consisting of a ratchet 11 hinged to the plate 10, which cooperates with a peg 12 fixed to the small frame 6.
The means of elastic support comprise a gas spring 13, which has a first end 14 hinged to the bed base 2 and a second end 15 hinged to the small frame 6 integral with the side 3 of the bed 4.
Operation of the bed structure with openable bed base according to the present invention is as follows.
The bed base 2 can be taken by the user from the closed position, visible in Figs. 1 and 2, to an open position, visible in Figs. 3 and 4, simply by lifting the bed base without exerting any effort due to the positive action of the gas spring 3 that, in the closed position, is compressed and therefore loaded with energy. During the rotation from the closed position to the open position, the ratchet 11 , which is freely hinged in the plate 10, integral with the bed base, moves beyond the locking peg 12, fixed to the small frame 6, and the bed base 2 is activated.
At this point, the free end of the ratchet 11 engages the peg 12, preventing a further downward rotation of the bed base and locking the latter in the open position, as can be seen in Figs. 3 and 4.
According to the invention, at the end of the guide 7 that receives the bed base 2 in the open position there is provided an elastic clamp 16 ("ciapanas"), designed for cooperating with the pin 17 of the wheel 9.
During opening of the bed, the bed base 2 is lifted upward in Fig. 4, until causing coupling of the ratchet 11 on the peg 12.
In this phase, the pin 17 of the screw 9 is not yet housed in the elastic clamp 16 (Fig. 4).
The deactivation operation is performed by further lifting of the bed base 2 from the position of Fig. 4, thereby causing elastic insertion of the pin 17 of the screw 9 in the clamp 16.
Simultaneously, the ratchet 11 is deactivated and, moreover, as there is no longer any action of the gas spring, which at this point has reached the end of its travel, the bed base 2 is closed, as its own weight is sufficient to cause the pin 17 of the wheel 9 to exit from its seat in the elastic clamp 16.
Therefore, according to the present invention, in order to be activated the bed base does not require to be lowered, as it activates itself, opposing the screw of the pulley with the elastic clamp (the so-called "ciapanas") at the end of travel.
To close the bed base, it is sufficient to lift the same bed base slightly, thereby causing it to rotate upward, to release the free end of the ratchet 11 which is positioned vertically, through gravity, as can be seen in Figs. 5 and 6.
From this vertical position, when the bed base is subsequently lowered, the ratchet 11 slides on the peg 12, without engaging it, allowing the bed base to rotate until reaching the closed position.
It has in practice been seen that the invention achieves the intended aim and objects.
In fact, a bed structure with openable bed base provided with an articulation device that facilitates the movement of the bed base, without any effort by the user, and allows reliable locking of the same bed base in any open position has been achieved.
Moreover, from each open position the bed base is automatically closable.
The bed structure according to the present invention is characterized in that the bed base is articulated to the side of the bed via a pair of wheels sliding in a curved guide, arranged under the plane of the mattress and positioned at a suitable distance from the head of the bed base, so as to allow an adequate angle of aperture, without the bed base interfering with the bottom of the bed.
The structure comprises a gas spring on each side of the bed acting between the bed base and the same side, positioned so as to express work that in each point of the rotation balances the thrust given by the weight of the bed base and related mattress.
The articulation device of the present invention allows easy opening of the bed base even with container.
Of course the materials used and the dimensions can be any according to needs.
