Description

. Field of the invention

The present invention relates to an openable assembly.
The present invention also relates to a furniture element comprising said assembly, a piece of kitchen furniture comprising said assembly and a method for opening an openable assembly.

. Prior art

A modular furniture element solution comprising a retractable, in particular horizontally sliding, door is known from document US-3567302 , for example. A further example of piece of furniture comprising horizontally sliding doors is given in DE-9317794 . US 3 567 302 A discloses an openable assembly comprising: at least one first container, comprising first container walls that at least partially delimit at least one first compartment, said at least one first compartment being accessible through at least one first opening; at least one second container, comprising second container walls that at least partially delimit at least one second compartment, said at least one second compartment being accessible through at least one second opening; at least a second opening closing device, that closes and opens at least a portion of said second opening; wherein said second opening closing device comprises at least a first closing element and wherein said at least one first closing element is movable in at least one closing position, in which they close said second opening, and at least one opening position, in which they at least partially open said second opening, making said second compartment accessible; and wherein said openable assembly comprises at least one seat, which at least partially receives both said at least one first closing element and wherein, when in said at least one opening position, said at least one first closing element is housed in said at least one seat, and wherein, when said at least one first closing element is housed in said at least one seat, they maintain said at least one first compartment accessible through said at least one first opening.
Pieces of furniture generally comprising one or more retractable, in particular sliding, doors adapted to be superimposed in order not to increase the dimensions of the piece of furniture itself when it is open, are known. For example, furniture solutions comprising one or more vertically sliding doors are shown in documents BE-1002679 and EP-2821576 . However, such furniture solutions have the disadvantage of providing an upper compartment which is always inaccessible.
From patent EP-0953713 it is known to make a piece of furniture having two doors sliding vertically in synchronous manner to make a first compartment or a second compartment alternatively accessible, wherein the size of said second compartment is double that of the first compartment and said second compartment is under said first compartment. By ascending, the sliding doors make the second compartment accessible, whilst closing the first compartment. Such solution, although advantageous in allowing the two sliding doors to be superimposed, make alternatively accessible either a first compartment or a second compartment, forcing to alternatively always close either said first compartment or said second compartment. Indeed, such solution is entirely unsuitable to make both said first and second compartment simultaneously accessible and to close them simultaneously both. Furthermore, the moving system of the sliding doors described by EP-0953713 is rather laborious to actuate because, in order to make the second compartment accessible, it requires to release one of the two sliding doors to make it ascend on a rail having the tortuous path, forcing to provide a handle which protrudes from the visible face of the door, in which said handle is made so as to be gripped by a hand to allow users to release the door and actuate the moving system by pulling the handle towards themselves. The necessary provision of such handle makes the appearance of sliding door less agreeable.
From international patent application WO-2009-113118 by the same Applicant, a system is known for concealing a foldaway element from sight, by pushing it downwards, from a raised position, in which it closes a compartment, to a lowered position, in which is it is hidden behind a front portion of a piece of furniture. Although advantageous, such solution can only be applied to low pieces of furniture, because the single foldaway element, which must be pushed from its upper edge, must be necessarily reachable by a normal user, e.g. a person of average height, when the foldaway element is in the raised position, also considering the dimension of said front portion of furniture which forces the user to act at a given distance from the foldaway element. Concurrently, such single foldaway element must be sufficiently small in size to be concealed behind the front portion of the piece of furniture and is therefore adapted to close compartments of limited extension.
The need is thus felt to provide a solution to the drawbacks of the prior art reported here.
The need is felt to provide an openable and closable solution for applications as furniture element, e. g. for kitchens, comprising closing elements, suitable for closing an opening of considerable dimensions, without because of this being difficult to manoeuvre.
Thus, the need is strongly felt to provide a compact, openable and closable solution for applications as furniture elements, e.g. for kitchens, comprising closing elements, adapted to close a piece of furniture of considerable height yet easily manoeuvrable by a normal user and which such closing elements, when are open, avoid to close-off some compartments of the piece of furniture.

It is an object of the present invention to provide an openable furniture element solution.
It is an object of the present invention to provide an openable furniture element solution, adapted to be used in kitchens.
It is a further particular object of the present invention to provide a closable furniture element solution, adapted to be used in kitchens, such as, for example, a piece of kitchen furniture.
This and other objects are achieved by an openable assembly according to claim 1, by a furniture element according to claim 12, by a piece of kitchen furniture according to claim 13, and by a method according to claim 14.

Said at least one first closing element 11 and said at least one second closing element 12 are movable in at least one closing position, or closed position, in which they close said second opening 9, and at least one opening position, or open position, in which they at least partially open said second opening 9, making said second compartment 8 accessible.
Said openable assembly 1 comprises at least one seat 16, which at least partially receives both said at least one first closing element 11 and said at least one second closing element 12.
When in said at least one opening position, said at least one first closing element 11 and said at least one second closing element 12 are housed in said at least one seat 16.
By providing said at least one seat 16 it is possible to keep said assembly equally compact when said second opening 9 is closed and when said second opening 9 is open, thus avoiding to configure said closing elements 11, 12 so as to increase the dimensions of said openable assembly 1.
According to a preferred embodiment, said at least one seat 16 is single seat 16. In this manner, when in said at least one opening position, said at least one first closing element 11 and said at least one second closing element 12 are both housed in said one seat 16.

This makes it possible to develop said openable assembly 1 vertically and to make accessible at least a third compartment 32 favourably located lower than said second compartment 8 when said closing elements 11, 12 are in open position. At the same time, it makes it possible to easily manoeuvre the openable assembly 1 even if the extension in height of said openable assembly 1 is greater than the height of a user.
According to a preferred embodiment, said movement sense 100 is directly upwards during the step of closing of said opening elements 11, 12, and is directed downwards during the step of closing of said opening elements 11, 12.
According to an embodiment, said movement sense 100 is directly substantially in horizontal direction. In other words, said synchronization device moves said at least one first closing element 11 and said second closing element 12 substantially in horizontal direction.
According to an embodiment, said third container 30 comprises at least one working surface 38 facing said second compartment 8.
According to an embodiment, said at least one third compartment 32 can be accessed through at least one third compartment opening 33, or third opening 33, of smaller size than said at least one second opening 9.
According to an embodiment, said second container 6 opens by lowering said closing elements 11, 12 and taking them behind said first container 2. In this manner, said closing elements 11, 12 are concealed from sight when the second container 6 is open. Preferably, said closing elements 11, 12 are frontally concealed for a normal user.
. According to an embodiment, said second container 6 closes by raising said closing elements 11, 12, taking them out from said seat 16, hidden by said first container 2.
According to an embodiment, illustrated for example in figure 1D , said movement sense 100 is directed sideways.
According to a variant embodiment, said movement sense 100 is directly substantially upwards. This makes it possible to develop said openable assembly vertically and when said closing elements 11, 12 are in open position, makes accessible a third compartment 32 located higher than said second compartment. For example, said third compartment 32 may comprise an extractable hanging element which extends downwards.
According to an embodiment, said synchronization device determines that said second closing element 12 moves at a faster speed than said first closing element 11. In this manner, it allows said first closing element 11 and said second closing element 12 to be completely housed in the seat 16 either at the same time or simultaneously. Furthermore, in this manner, said at least one first closing element 11 and said at least one second closing element 12 are at least partially superimposed when they are housed in said seat 16.
According to an embodiment, said first closing element 11 and said second closing element 12 have substantially the same extension.
