Definitions
- the present invention relates to a bed structure comprising a base container, a mattress base such as a mesh mattress base or a slatted mattress base or similar, and a reversible moving mechanism for moving the mattress base.
- Such bed structures comprise a mattress base supported in an articulated manner by a box container.
- the mechanisms that enable the end of the mattress base to be lifted comprise an articulated quadrilateral and elastic elements or electric actuators that enable the mattress base and mattress to be lifted with minimum effort to thus give access to the container below the mattress base. These mechanisms, in order to permit easy access to the container, guide the mattress base, so as to tilt the mattress base, lifting only one end thereof.
- Both the lifting mechanisms of the mattress base require a certain physical effort from the user, despite the help of elastic elements, to take the mattress base and mattress from a first to a second stable position, in other words from a closed position to an open position of the container and vice versa.
- hybrid lifting mechanisms exist that enable the mattress base to be taken both to the tilted position and to the raised horizontal position.

- the hybrid lifting mechanisms of known type have at least two degrees of freedom of movement that are activatable in succession that do not permit continuous movement of the mattress base between the three stable positions. In order to pilot this movement, elastic elements and the intervention of the user are envisaged.

- the mattress base is moved to the stable open horizontal position protruding frontally beyond the volume of the box container of the bed structure. Accordingly, these bed structures have to be used in bedrooms that are sufficiently large to permit correct positioning of the mattress base in the stable open horizontal position.

- the force required to the linear actuator 17 is increased when the mattress base 6 is in a tilted position and is reduced when the mattress base 6 is in the lower and upper horizontal positions.

Description
- The present invention relates to a bed structure comprising a base container, a mattress base such as a mesh mattress base or a slatted mattress base or similar, and a reversible moving mechanism for moving the mattress base.
- For several years, there have been mechanisms on the market that enable an end of the mattress base of a bed structure to be raised so as to enable the volume below to be accessed and to be used to place objects therein. Such bed structures comprise a mattress base supported in an articulated manner by a box container.
- The mechanisms that enable the end of the mattress base to be lifted comprise an articulated quadrilateral and elastic elements or electric actuators that enable the mattress base and mattress to be lifted with minimum effort to thus give access to the container below the mattress base. These mechanisms, in order to permit easy access to the container, guide the mattress base, so as to tilt the mattress base, lifting only one end thereof.
- Further, mechanical mechanisms are available on the market that enable the mattress base and mattress to be lifted parallel to the floor to enable the bed to be remade easily. In this manner, the mattress base and the mattress are sufficiently raised from the floor to enable a user to rearrange the blankets, maintaining a substantially erect position, avoiding the need to bend.
- This vertical lifting of the mattress base, maintained in a horizontal position with respect to the floor, permits access to a possible container below, but, in view of the small height reached from the ground, access is limited and inconvenient.
- Both the lifting mechanisms of the mattress base require a certain physical effort from the user, despite the help of elastic elements, to take the mattress base and mattress from a first to a second stable position, in other words from a closed position to an open position of the container and vice versa.
- In the first stable position, the bed must not lift up on its own whereas in the second position the bed must not fall back to its initial position. For this reason, some mechanisms of this type also contemplate versions provided with electromechanical actuators, so as to lift the bed with nil effort.
- Further, hybrid lifting mechanisms exist that enable the mattress base to be taken both to the tilted position and to the raised horizontal position.
- For example, the patent for
Italian utility model No 277112 - Known hybrid lifting mechanisms are assisted by elastic elements and must ensure three stable positions of the mattress base, a closed position and two open positions - tilted and horizontal. Also in this case, in order to take the mattress base from one stable position to the other, the intervention of a user is necessary, which entails a certain physical effort.
- Moreover, the hybrid lifting mechanisms of known type have at least two degrees of freedom of movement that are activatable in succession that do not permit continuous movement of the mattress base between the three stable positions. In order to pilot this movement, elastic elements and the intervention of the user are envisaged. This makes the operation of the lifting mechanism difficult, not always foreseeable and susceptible to possible errors.
- Further, by using hybrid lifting mechanisms of known type, the mattress base is moved to the stable open horizontal position protruding frontally beyond the volume of the box container of the bed structure. Accordingly, these bed structures have to be used in bedrooms that are sufficiently large to permit correct positioning of the mattress base in the stable open horizontal position.

linear actuator 17 of thereversible moving mechanism mattress base 6 between the lower horizontal position, the tilted position and the upper horizontal position. - The
linear actuator 17 locks themattress base 6 in any position reached between the lower horizontal position and the upper horizontal position. - In particular, the
mattress base 6, when it is in the lower horizontal position, is supported by the upper edge of thebase container 5 or alternatively it is supported byabutting elements 19 fixed to the inner walls of thebase container 5. In this manner, thereversible moving mechanism mattress base 6 is in the lower horizontal position. - In particular, the upper horizontal position of the
mattress base 6 is achieved when thelinear actuator 17 reaches the end of the extension stroke and thereversible moving mechanism mattress base 6, of the mattress and of the blankets. - Preferably, the
linear actuator 17 is of electromechanical type, but it is possible to use indifferently a linear actuator of pneumatic type, hydraulic type, etc. - The
linear actuator 17 is controlled by an opening button that drives the extension stroke and by a closing button that drives the retracting stroke. - Advantageously, the
mattress base 6, and in particular the vertical projection thereof, is entirely contained inside the shape of thebase container 5 in the lower horizontal position, in the tilted position and in the upper horizontal position. - Accordingly, the vertical projection of the
mattress base 6 is entirely contained inside the shape of thebase container 5 in any position reached between the lower horizontal position and the upper horizontal position. - In particular, the
linear actuator 17 is hinged to the lever of thereversible moving mechanism - The bed structure 1 comprises a
support plate 4 fixed to an inner wall of thebase container 5 and anangular profile 8 fixed to themattress base 6. - The levers of the
reversible moving mechanism support plate 4 to theangular profile 8. Consequently, the levers connect thebase container 5 to themattress base 6. - In particular, the levers of the
reversible moving mechanism curved lever 9 and asecond lever 10 that are hinged to one another and, respectively, to thesupport plate 4 and to theangular profile 8. - It should be noted that the levers of the
reversible moving mechanism third lever 11 that has a first end hinged in an intermediate point of thesecond lever 10 and a second end hinged to thesupport plate 4. - In greater detail, the levers of the
reversible moving mechanism curved lever 12 having a first end hinged to thesupport plate 4 together with the second end of thethird lever 11. - In greater detail, the levers of the
reversible moving mechanism fifth lever 13 that has a first end hinged to a second end of thefourth lever 12 and a second end hinged to theangular profile 8. - The levers of the
reversible moving mechanism driving lever 14 that connects by hinges an intermediate point of thefirst lever 9 to an intermediate point of the fourth lever 12 (not shown in the figures). - Advantageously, alternatively (as represented in the figures), the
driving lever 14 is hinged to an intermediate point of thefirst lever 9 and is connected to an intermediate point of thefourth lever 12 and to an intermediate point of thethird lever 11 respectively by a first and a second connectingrod driving lever 14 is hinged at the same point to an end of the first connectingrod 15 and to an end of the second connectingrod 16. The first connectingrod 15 is hinged to an intermediate point of thefourth lever 12 and the second connectingrod 16 is hinged to an intermediate point of thethird lever 11. - It should be noted that the
linear actuator 17 is connected by hinges to anextension 18 of thesupport plate 4 and to thedriving lever 14. - In particular, but not necessarily, the bed structure 1, according to the preferred embodiment of the invention, has two
moving mechanisms container 5 byrespective support plates 4 and are connected to themattress base 6 by corresponding connectingangular profiles 8. - The two
reversible movement mechanisms figure 2 . - Both the
reversible movement mechanisms - The bed structure 1 further comprises a synchronizing
bar 3 that connects intermediate points of thefirst lever 9 of the tworeversible movement mechanisms - The synchronizing bar is configured to stiffen the structure when the bed is raised and to synchronize the movements of the two
reversible movement mechanisms - In one embodiment of the invention, there may be only one
linear actuator 17, fitted on one of the tworeversible movement mechanisms bar 3 has the task of transferring the movement of thefirst lever 9 of one of the twomovement mechanisms lever 9 of theother movement mechanism - In an alternative embodiment, two
linear actuators 17 can be mounted, one for each of the twomovement mechanisms mechanisms - When the
linear actuator 17 is activated in extension, it moves the drivinglever 14, which in turn rotates thefirst lever 9 and thefourth lever 12. - The
first lever 9 drives thesecond lever 10, which in turn, guided by thethird lever 11, moves one end of the connectingangular profile 8. - The
fourth lever 12 on the other hand, owing to thefifth lever 13, moves the intermediate point of the aforesaid connecting angular profile. - Consequently, a rotation-translation movement of the connecting angular profile takes place, and accordingly, also of the
mattress base 6, which moves to the tilted access position with the volume bounded by thebase container 5, shown infigure 5 . - The rotation movement enables an end of the
mattress base 6 to be lifted so as to give easy access to thecontainer 5, whereas the translation movement enables the other end to be moved away from apossible headboard 20 of the bed structure 1. This enables the mattress not to interfere with theheadboard 20, when this configuration is reached, as can be seen infigure 5 . - From the tilted position of the
mattress base 6, continuing with the extension stroke of thelinear actuator 17, all the levers continue their own movement, but from this point on, they induce the connectingangular profile 8 to reverse the rotation direction and stop the translation, so as to take themattress base 6 to the upper horizontal position and lifted as much as necessary for remaking the bed easily. - Advantageously, in this upper horizontal position, as can be seen in
figure 6 , themattress base 6 leaves a sufficient space between themattress 7 andheadboard 20, to enable the hands to be inserted to rearrange the blankets but does not protrude beyond the volume of the closed bed so as to be able to be used in rooms of reduced space. - In this position, the actuator is at the maximum of the stroke and to prevent the actuator being urged beyond, a
tooth 21 obtained on thedrive lever 14 abuts against thethird lever 11. - The opposite movement is obtained by driving the actuator in the opposite direction. The
reversible moving mechanism mattress base 6 from the upper horizontal position to the tilted position, to then return to the lower closed horizontal position of thebase container 5. - In one preferred embodiment, the reversible moving
mechanism rods lever 14, which in turn rotates thefirst lever 9 and thefourth lever 12 by means of the first connectingrod 15 and guided by the second connectingrod 16. - Advantageously, the presence of the first and the second connecting
rod - Observing
figures 4-6 , it can be seen that the action of the drivinglever 14 on thefourth lever 12 is operated by the second connectingrod 16, the direction of which with respect to thefourth lever 12 is influenced by thefirst rod 15. - The presence of the connecting
rods fourth lever 12 to be modified, extending the arm at the start and end of the movement and when themattress base 6 is respectively in the lower horizontal position and in the upper horizontal position, and reducing the arm when themattress base 6 is in the tilted position. Owing to the presence of the two connectingrods linear actuator 17 is increased when themattress base 6 is in a tilted position and is reduced when themattress base 6 is in the lower and upper horizontal positions. In this manner, the reversible movingmechanism rods - The movement of the
mattress base 6, owing to the fact that the reversible movingmechanism mattress base 6 to the tilted position, the user just has to keep an opening button pressed until themattress base 6 has lifted sufficiently to permit access to the container below. From this point, to close the bed structure 1 again, the user just needs to keep a closing button pressed until themattress base 6 has again reached the lower horizontal position. - When the user desires to lift the bed structure 1 to rearrange the blankets, the procedure to be followed is identical to the preceding procedure except that instead of stopping in the tilted position, the user has to continue to press the opening button until the
mattress base 6 reaches the upper horizontal position. - Closing occurs in the same manner as previously disclosed. By passing through the tilted position of the
mattress base 6, the user can decide to stop the movement by interrupting the interaction with the closing button, to place blankets or other objects inside the container again.
