Technical Field

The present invention relates to furniture items, in particular furniture items with sliding and swinging door leaves (leaf) in order to be folding door leaves, more particularly equipped with compartments that can be closed by the door leaves. The invention also relates to a method for said piece of furniture.

Background

Many furniture items are equipped with sliding and folding door leaves to allow reducing the size of the door leaf itself in the open position, see for example WO 2019012435. WO2019012435, like many other models, uses elastic elements to move the glide 210 (as described above) and bring the door leaf to the end-of-travel position. However, the elastic element makes the structure complicated, the cost is high and the force is generated less linearly.

Disclosure of Invention

The main object of the present invention is to improve this situation of the prior art, the invention being defined in the appended claims, wherein the dependent claims define advantageous variants.

Another object is to create a piece of furniture with a compartment that can be closed by a sliding and bellows-like foldable door leaf, which is easy to handle, requires less movements by the user and does not fatigue too much during use.

A method of constructing a piece of furniture is proposed, the piece of furniture comprising, in use:

the door leaf is provided with a door leaf,

a linear guide member which is inclined downward,

a body slidingly mounted on the guide and connected to the door leaf to pull the latter to the end-of-travel position,

wherein the body moves on the guide to pull the door leaf by means of gravity only.

Another aspect of the invention relates to an article of furniture comprising, in use:

a (vertical or horizontal) door leaf, which is a linear guide that can slide and swing to close the compartment, and is inclined downward;

a body slidingly mounted on the guide and connected to the door leaf to pull the latter to the end-of-travel position;

wherein the body is configured to be movable on the guide to pull the door leaf towards the end-of-travel position solely by means of gravity.

In a preferred variant, the body is slidably mounted on two parallel downwardly inclined guides for better stability.

In a preferred variant, the body is slidably mounted on the guide, or on a plurality of guides, by means of a slide, so as to move obliquely when the slide slides on the guide or guides.

In a preferred variant, the body has such a weight or a weight sufficient to make the body slide on the guides to pull the door leaf by means of gravity only. However, gravity may act not only on the body to cause the body to slide on the guide but also on other elements integral with the body, for example on at least one slide slidingly supporting the body on the guide or guides.

In a preferred application, the method is carried out on an article of furniture comprising:

a body defining a compartment with a front opening,

-a (vertical or horizontal) door, which is slidable and oscillating to close the front opening,

an L-shaped guide comprising two linear sections joined together, wherein

The first section is parallel to the edge of the opening, an

The second section is arranged orthogonal to the first section and in correspondence of the external side of the body along the depth direction of the compartment;

-a control element translatable parallel to and along said external side; wherein

The side edge of the door leaf is slidingly coupled to the L-shaped guide, an

Opposite side edges of the door leaf are connected to the control element in a swinging manner such that a linear reciprocating movement of the control unit moves the door leaf to a first position, in which the door leaf closes the opening, or a second position, in which the door leaf is clear of the opening and placed next to said outer side, wherein

The control member coinciding with the aforementioned slidably mounted body, or

The control element is connected to the aforementioned slidingly mounted body to be moved in order to displace the door leaf into the first or second position.

According to a variant, the article of furniture comprises a first leaf as defined above and a second leaf connected to the first leaf in an oscillating manner (for example, the first leaf and the second leaf are hinged to each other). The first door leaf is slidingly coupled to the guide at its side closest to the second section. One side of the first door leaf is hinged to the translatable control member about a first axis. The opposite side of the first door leaf is slidably coupled to the guide, in particular, it may be hinged to the second door leaf about a second axis. When the first door leaf is not directly coupled to the guide, the first door leaf passes through the second door leaf. However, the translatable control element may thus operate the door system, transmitting kinetic energy to the door system by a translational reciprocating movement of the control element itself, which is a movement developing parallel to the depth direction of the compartment.

It has therefore turned out that the door leaves can be folded bellows-like about at least one axis and can slide between a closed position of the compartment, in which the door leaves are arranged coplanar with each other in the front of the compartment, and an open position of the compartment, in which the door leaves are folded over each other and placed along said side of the compartment.

By the reciprocating movement of the translatable control element, the door leaf can be moved easily.

In other words, the control element is movable between two positions:

a rest position in which the control element is placed in front of the outer side (side) and does not substantially project forward, and

a position in which the control element is horizontally offset with respect to the external side (and with respect to the compartment) to project forward from the external side and the compartment (the translatable control element moves in a direction toward the front opening of the compartment and away from the rear of the compartment).

By the reciprocating movement of the translatable control element, the door leaf can be moved easily.

The exterior side of the compartment may be a side or a top or a bottom.

Thus, one or more door leaves may be hidden immediately above or below the compartment. In the first case, the L-shaped guide has two horizontally arranged sections, while in the second case the first section is horizontal and the second section is vertical. That is, the aforementioned variant with one or two door leaves can in turn be implemented by assembling the door leaves moving horizontally or vertically.

In the first case, the aforementioned axis is vertical, in the second case, it is horizontal. In the following, for the sake of brevity, we will refer to the case of a horizontally hinged door leaf, understanding that the second case corresponds to the first control case.

The first hinge axis is supported by the translatable control member such that the first hinge axis is horizontally rigidly translatable. This first shaft is thus horizontally movable between two extreme positions, namely a rest extreme position and an advanced extreme position (further from the compartment). For the reciprocating movement of the translatable control element, here both the movement of the first shaft and the displacement of the second shaft along the guide correspond, wherein the movement of the first shaft always starts from the first extreme position, reaches the second extreme position, and returns again to the first extreme position. This movement of the second shaft along the guide occurs in one direction and then in the opposite direction during two successive reciprocations of the translatable control element. In the first extreme position, the first axis is arranged substantially coplanar with or close to the plane of the first opening, this configuration corresponding to the closed and open position of the door leaf. In the second extreme position, the axis is spaced orthogonally from the plane of the front opening, this configuration here corresponding to the intermediate position of the door leaf.

Preferably, the article of furniture comprises means for rotating the second door leaf relative to the first door leaf about the second hinge axis during displacement of the door leaf towards the second position. In particular, the device is configured so that the aforementioned rotation is stepwise and synchronized with the translational movement of the or each door leaf. For example, the article of furniture comprises means for rotating the second door leaf about the second hinge axis towards/away from the first door leaf during displacement of the door leaf towards the second/first position.

Preferably, the translatable control element comprises a vertical wall translatably on the compartment and a vertical wall mounted with respect to the compartment, sliding in a direction substantially parallel to what is considered to be the depth of the compartment. More preferably, the translatable control element comprises two vertical walls arranged orthogonally to each other and movably mounted on and with respect to the compartment. In a first variant, the two vertical walls are arranged L-shaped and movably mounted on and relative to the compartment for delimiting the compartment or compartments in which the door leaves are stored when stacked. In a second variant, the two vertical walls are arranged T-shaped and mounted on the compartment and relative to the compartment to close a second compartment or compartment in which the door leaves are stored when stacked. This allows to cover the door leaf when it is not in use, protecting it from dust and protecting the mechanism of the door leaf from accidental impacts.

It should be noted that in some preferred variants, the movable mounting body implements a resetting means for exerting a force on the translatable control element. The weight of the movably mounted body serves to move the translatable control element, for example, to a rest position, i.e., a first extreme position. Thus, the user only has to pull the translatable control element towards itself to move the translatable control element from the first extreme position to the second extreme position, and the translatable control element will automatically return to its position when released because it is pulled by the weight of the moveably mounted body when sliding on the inclined guide or guides.

Preferably, the two parallel guides are integral with the furniture frame and arranged in the direction of the depth of the article of furniture.

Preferably, the translatable control element is an aluminum frame.

Drawings

The advantages of the invention will be more apparent from the following description of a preferred embodiment of an article of furniture with reference to the accompanying drawings, in which:

FIGS. 1-2 show three-dimensional front views of an article of furniture;

figures 3-4 show rear three-dimensional views of the furniture item of figure 1.

Detailed Description

In the drawings, like reference numbers indicate identical or conceptually similar parts, and elements are described as in use.

The article of furniture MC according to the invention comprises a module formed by compartments 20, the compartments 20 defining a space open towards the outside, delimited by a bottom 22, a top 24, two vertical side walls 26 spaced from each other by the width of the compartment 20, and a rear wall 28. The compartment 20 forms a front span which can be covered by two door leaves 30, 32 slidable in front of the compartment 20. The door leaves 30, 32 can be moved like bellows in the front of the compartment 20 to close the compartment 20 or to make the compartment 20 accessible from the outside. During the movement, the door leaves 30, 32 always remain vertical and change their relative position and relative position with respect to the compartment 20. When the compartment 20 is closed, the door leaves 30, 32 are adjacent to each other and coplanar, while for opening the compartment 20, the door leaves 30, 32 are movable to stack themselves one on top of the other on one side of the compartment 20.

The structure of the displacement mechanism for the door leaves 30, 32 is not essential and may for example be the structure described in WO 2019012435.

Preferably, the article of furniture MC comprises a movable frame or side or element 60 that can translate linearly along a direction parallel to the wall 26 (or, in other words, parallel to the section 54 or orthogonal to the wall 28). The movable frame or side or element 60 can translate linearly, for example, by means of a linear guide or other known means mounted on one side of the compartment, for example via slides.

By means of the actuating element 60, the door leaves 30, 32 can then be moved in front of the compartment 20, which avoids moving the door leaves 30, 32 by hand in a difficult manner or by other means. The coupling between door leaf 32 and element 60 is advantageous because the user need only move element 60 back and forth (e.g., via a handle) to move door leaves 30, 32 together from coplanar to stacked and concealed, or from stacked and concealed to coplanar.

Said element 60 is movable back and forth parallel to the vertical wall 26, so that the front wall 64 of the element 60 rests on the front edge of the wall 26 when the compartment 20 is closed by the door leaves 30, 32, to be eventually coplanar with the door leaves 30, 32.

To initiate movement of the door leaves 30, 32, the pulling of the element 60 is sufficient to pull the door leaves from the furniture item (towards the user, i.e. away from the rear wall 28). This displacement of the element 60 gives, through the door leaf 32, a thrust to the door leaf 30 to push its movement.

The article of furniture MC comprises return means for the element 60 to return the element 60 towards the wall 28. In this way, the user is only required to pull the element 60 towards himself, after which the element 60 can be released and will end its travel together with the door leaves 30, 32 operated by the resetting means.

The control element 60 is integral with the vertical guide 200, and the two glides 210 can slide linearly in the vertical guide 200. Each glide 210 is rigidly constrained to the other glides, for example via a rod 240, and is slidably constrained to a respective inclined straight rod 230 integral with the furniture frame and mounted, for example, on the outside of the side 26. The two bars 230 are parallel, spaced apart from each other and inclined with respect to the horizontal.

The rod 240 is horizontally slidable without being disengaged along the rod 230, and can simultaneously slide vertically on the guide 200 by means of the slider 210.

When the element 60 moves back and forth to move the door leaves 30, 32, the glide 210 slides along the rod 230 and thus cooperatively up and down along the guide 200. In this way, the movement of the element 60 becomes stable to avoid jamming or vibration.

The weight of the rod 240 (and/or all or some of the components integral with the rod 240) is designed such that the force of gravity acting alone on the rod 240 (and/or all or some of the components integral with the rod 240) is sufficient to drag the rod 240 and glide 210 together with the element 60 downwards, i.e. towards the lower end of the rod 230. This limit position corresponds here to a rest position with respect to one or each of the end-of-travel positions of the element 60, i.e. when the rod 240 is inserted inside the furniture frame or completely extracted from the frame.

In this way, there is constantly a return force on the element 60, constituted by the force of gravity pulling the rod 240 (and/or all or some of the parts integral with the rod 240) downwards along the guide 230.

It is clear that the restoring force is generated in a simple manner with few parts, without energy consumption and with an almost constant strength.
