DESCRIPTION

Background of the invention.

The present invention refers to convertible furniture, i.e. to a furniture structure in which? during its opening it is possible to slide extensible guides inserted and fixed inside the furniture itself, and on which to subsequently place shelves also located inside the furniture in question, in order to create a table and some worktops after having blocked their closure with a special mechanism. Once the guides have been extended it will be? It is possible to position legs, in steel, aluminum or plastic material by means of a ?male and female? mechanism. spring operated by a button. They are housed inside the furniture in which the extendable system will be placed. placed. This convertible structure is used mainly, but not limitedly, as furniture for the kitchen, living room and bedroom, in such a way as to be able to extract, if necessary, a table or work surface. The extendable system covered by the patent, therefore, finds effective application when there is the necessity? to optimize space, hiding the entire table when it is not needed. In the furniture sector, are there many convertible structures known such as sofa beds, or folding tables, etc? The main purpose of such furnishings? create structures capable of performing different functions without taking up domestic spaces. Compared to the prior art, the invention creates a furniture structure with mechanisms that are easily operated and operated without physical effort, thus reducing the user's effort to a minimum.

Fundamental for the furniture sector? aesthetics. For this reason the present invention is equipped with mechanisms that we will describe better later, which are simple to update and which do not limit the design aspects.

Further task of the present invention? the creation of a convertible piece of furniture, capable of overcoming the drawbacks of the known art. As part of this task, the convertible furniture of the invention in question is created as a perfectly functional structure both during its opening and at the moment of its closing via its extendable guides, and therefore easily convertible thanks to the simple locking mechanisms and unlocking of the same ones that guarantee and ensure reliability? and safety in their use, also thanks to the fixing system of the stabilizing legs.

A further purpose of the present invention? that of providing convertible furniture that is easy to create using commercially available elements, and which is also competitive from an economic point of view.

These purposes and others that will appear better later on are achieved by a convertible furniture structure, i.e. by an extendable system, capable of containing guides inside the furniture, which, once their maximum extension has been reached, are blocked by simple , but innovative, snap mechanisms. These guides are fixed inside the furniture, suitably hidden, so that a user will only need to use them. simply pull with light pressure the front of the drawer or container in which the extendable system is located? placed, to extract the table or extractable shelf.

At the base of the door leaf and/or guide extension bar, two legs will be inserted, as we will better observe below, without limitation, to support both the guides and the entire structure converted into a table. These legs are made of lightweight material such as aluminium, and are also equipped with an easy-to-use mechanism for attaching them. These table legs are placed in the furniture frame together with shelves which are positioned on the base of the guides once extended to assemble a table.

The advantage of this furniture? that of being able to be used without limitations as a compartment positioned inside a kitchen, living room or bedroom, to limit the spaces as previously described, or, again without limitations, as bedroom furniture to accommodate a desk.

Further characteristics and advantages will emerge more from the description of preferred, but not exclusive, embodiments of the invention, illustrated by way of example and not limited to the attached drawings.

Preferred embodiments.

Table 1? a perspective view of the furnishing structure where, according to the present invention, some shelves for updating a table (11), a load-bearing structure for the extendable guides (12), and 2 "trays" can be observed inside its frame. (13 and 14) where the table legs are stored.

Table 2? a perspective view that illustrates a subsequent phase, that is when you start to open the structure of the furniture to create a table. In fact, you can see the extendable guides (14) and the shelves (15) ready to be placed on them, and the front of the lower furniture drawer (16) containing the table legs.

The extendable guides, table 6, are shaped to slide one inside the other, and fixed inside the furniture itself. These guides contain a locking lever equipped with a spring table 4 indicated at number 17 fixed with a screw to avoid sudden closure of the guides themselves when said guides are in the extended position. How already? described said lock lever ? aligned in the last two guides in such a way that in the extension phase of said guides it manages to snap and/or open when the latter have completed their travel, avoiding sudden and/or accidental closing, and thus allowing the user to position the shelves.

As regards the legs supporting the table, as previously described, these are housed in 2 special metal trays table 1 fig. 13 and 14, are light and are therefore taken by a user to be fixed using a ?male and female? mechanism. spring controlled by a button table 8 fig 22, in turn placed on a front bar Table 6 fig 41. This door and/or bar is? observable in table 2 indicated at number 31 and has a triple functionality, the first is to ensure that the guides are perfectly aligned and elongated, the second allows the user with considerable ease to extend the guides themselves simply with one hand, and the third functionality? ? to attach the table legs to the ?male and female? mechanism.

To better understand the functioning of the ?male and female? mechanism spring controlled by a button just described fixed on the legs of the table and on the door indicated in table 2 number 31, in this regard it is necessary to observe table 7 at number 20 where a first hook base is indicated which is not limitedly fixed with screws on the leg same as the table, which slides on a second hook base fixed on the door with screws and indicated at number 21. This hook is guaranteed with a simple pressure by the user until an internal metal lock is released. To release the lock, just look at table 8 where the button at number 22 is illustrated. By pressing this button with light pressure from the user, the lock is opened and the table leg can be opened. easily slide to be unhooked.

And it is worth pointing out that the table legs, once inserted, also have the utility to always keep the table in parallel with the floor, and once the guides, shelves and legs themselves are reinserted inside the furniture structure, everything will be completely hidden from view.

In the description given so far, yes? understood how the invention achieved the intended task and objectives, in fact yes? a convertible furniture structure has been created whose opening and closing system is quick and easy, as well as? safe for its user, and it is It is important to reiterate some advantages, namely that the structure can? be placed inside a piece of furniture such as not limited to a kitchen to best arrange the spaces.

From what has been explained so far, the convertible furniture structure according to the invention is susceptible to numerous modifications and variations, all falling within the scope of the inventive concept.

Furthermore, all details can be replaced by technically equivalent and advantageous elements.

All the materials used as well as? the dimensions may be any according to needs and the state of the art.

To better clarify what has been explained so far, we return to the description of table 3 where from the perspective view of the furniture once opened, we can see the shelves resting entirely on the guides, and the table legs inserted.

To better understand the mechanisms that make up the furniture structure in the present invention we will begin by describing with the help of Table 4 the locking lever with snap spring whose use is applied to block the return of the extendable guides once they are opened, and therefore to prevent the user of this furniture from suddenly closing the guides in the event of a collision or accidental event.

In this regard, in table 4 we observe a perspective view of the locking lever, which at the end of the travel of the extendable guides during their opening, automatically snaps, interlocking the guides themselves, preventing them from closing.

This mechanism also represents a novelty? how much? element of safety and practicality? in the use of convertible furniture and allows the manufacturer to create self-locking guides without altering the design of the furniture itself.

To unlock this mechanical system when the user wants? closing the table will be? It is sufficient to use two fingers to apply slight pressure on the hook mechanism. In this way the mechanism will be released, returning to realignment between the guides, allowing the guides themselves to close again.

In the release position to better understand this mechanism, you can? observe table 5 in which in its perspective view it shows the locking lever 18 not occupying positions such as to affect the smoothness of the extendable guides as it is perfectly aligned with them.

In table 6 we find a perspective view of the open guides to complete the convertible furniture with sliding guides. These guides are made of lightweight material, not limited to aluminium. Said guides are made from a series of uniform metal bars, preferably made of aluminium, observable in table 9, joined telescopically to each other by the shape of the profiles, or not limitedly by sliding mechanical systems, and represent a further novelty. of the invention in question, new for their use compared to the known art and fixed inside the frame of the convertible furniture. In this way, further safety is achieved for the user who does not have to deal with structures that are tiring and/or complex in their mechanical nature.

Table 8? a perspective view of a table leg which initially in the closed state of the convertible furniture is stored in its frame and is easily picked up by the user to be hooked up using the mechanical system tab. 7 fig. 20 and fig.

21.

In table 8 there is a perspective view of the table leg, which in order to be released requires the user to press the button 22 and apply light upward pressure.

With reference to the cited tables regarding the convertible furniture structure according to the described invention, you can be susceptible to any technical variation that improves the state of the art, and will be therefore protected by the spirit of the following claims
