“MECCANISMO PER MOBILI” "MECHANISM FOR FURNITURE"

DESCRIZIONE DESCRIPTION

Il presente trovato riguarda la possibilità di variare agevolmente l’assetto di alcune parti dei mobili di seduta (schienali, braccioli, poggiagambe, ecc.) ed anche dei letti (testate, mensole, ecc.) per i quali possa essere utile la trasformabilità. The present invention relates to the possibility of easily varying the arrangement of some parts of the seating furniture (backrests, armrests, leg rests, etc.) and also of the beds (headboards, shelves, etc.) for which transformability may be useful.

Allo stato attuale della tecnica sono noti meccanismi che consentono di variare, secondo necessità, l’assetto dello schienale ed il suo ingombro a sporgere da uno schienale sottostante. Sono altresì noti meccanismi che, diversi dai primi ed anche più diffusi, vengono montati nei mobili di seduta dotati di poggiapiedi da sollevare all'occorenza da una posizione pressoché verticale a quella pressoché orizzontale di utilizzo. In the current state of the art, mechanisms are known that allow you to vary, as needed, the backrest structure and its overall dimensions to protrude from an underlying backrest. Mechanisms are also known which, different from the first and also more widespread, are mounted in seating furniture equipped with footrests to be raised if necessary from an almost vertical to an almost horizontal position of use.

Tutti i meccanismi noti, sia quelli per gli schienali come quelli per i poggiapiedi ed altri ancora, risultano particolarmente onerosi ed ingombranti. All the known mechanisms, both those for the backrests and those for the footrests and others, are particularly burdensome and bulky.

Scopo del presente trovato è quello di proporre una sorta di meccanismo universale di minimo ingombro utilizzabile a coppie e da fissare a due telai rigidi, di cui uno appartenente alla struttura del mobile e l'altro alla parte da movimentare, oppure alle parti in legno eventualmente presenti all’interno di questi. The purpose of the present invention is to propose a sort of universal mechanism of minimum bulk that can be used in pairs and to be fixed to two rigid frames, one of which belongs to the structure of the furniture and the other to the part to be moved, or to the wooden parts if necessary. present within these.

Il meccanismo in oggetto prevede almeno tre elementi imperniati tra loro in successione ed almeno due martinetti a gas di tipo noto agenti ciascuno tra uno degli elementi esterni e quello intermedio. The mechanism in question provides at least three elements hinged together in succession and at least two gas jacks of a known type each acting between one of the external elements and the intermediate one.

Per meglio descrivere il trovato in oggetto sono state allegate due tavole di disegno dove, a solo titolo indicativo e non limitativo, sono rappresentate: To better describe the invention in question, two drawing tables have been attached where, for indicative and non-limiting purposes only, the following are shown:

le FIGG. 1 e 2, che mostrano la vista dal basso e la sezione longitudinale XX di un meccanismo realizzato secondo il trovato; la FIG. 3 che mostra un particolare ingrandito della FIG. 2; FIGS. 1 and 2, which show the bottom view and the longitudinal section XX of a mechanism made according to the invention; FIG. 3 showing an enlarged detail of FIG. 2;

le FIGG. 4-5-6 che mostrano altrettanti assetti del meccanismo delle FIGG. 1 e 2. FIGS. 4-5-6 which show as many arrangements of the mechanism of FIGS. 1 and 2.

Con riferimento ai disegni allegati, il meccanismo in oggetto comprende tre elementi rigidi 1 , 2 e 3 di cui i due esterni 1 e 3 sono due bracci aventi una conformazione prevalentemente ad U per essere imperniati all’esterno dell’elemento centrale 2 in 20 e 21. Ognuno di detti bracci 1 e 3 è ulteriormente collegato a detto elemento 2 me-diante un martinetto a gas di tipo noto, rispettivamente 4 e 5, detto marti-netto essendo alloggiato all’interno del braccio 1 e 3 sagomato ad U. With reference to the attached drawings, the mechanism in question comprises three rigid elements 1, 2 and 3 of which the two external elements 1 and 3 are two arms having a predominantly U-shaped conformation to be hinged outside the central element 2 in 20 and 21. Each of said arms 1 and 3 is further connected to said element 2 by means of a gas cylinder of a known type, 4 and 5 respectively, said cylinder being housed inside the U-shaped arm 1 and 3.

In particolare, il martinetto a gas 4 è imperniato in 41 nel braccio 1 ed in 40 nell’elemento intermedio 2 in modo che, ruotando detto braccio 1 intorno al proprio incemieramento 20 con l’elemento intermedio 2, basta superare la posizione di allineamento dei tre incemieramenti 41-40-20, che è anche quella di massima compressione del martinetto 4, perché quest'ultimo agisca in estensione fino a disporre automaticamente il braccio 1 nell'assetto voluto. In particular, the gas cylinder 4 is hinged at 41 in the arm 1 and at 40 in the intermediate element 2 so that, by rotating said arm 1 around its hinging 20 with the intermediate element 2, it is sufficient to overcome the alignment position of the three junctions 41-40-20, which is also that of maximum compression of the jack 4, so that the latter acts in extension until the arm 1 is automatically arranged in the desired position.

Un comportamento analogo ha il braccio 3 che, ruotando intorno al proprio incemieramento 21 con l’elemento intermedio 2, si dispone nell'assetto voluto previo superamento della posizione di allineamento dei tre incemieramenti 51-50-21, che è anche quella di massima compressione del martinetto 5, detto martinetto essendo imperniato in 50 nell’elemento intermedio 2 ed in 51 nel braccio 3. An analogous behavior has the arm 3 which, by rotating around its own junction 21 with the intermediate element 2, arranges itself in the desired position after exceeding the alignment position of the three hinges 51-50-21, which is also that of maximum compression. of the jack 5, said jack being pivoted at 50 in the intermediate element 2 and at 51 in the arm 3.

Onde consentire di fermare i bracci 1 e 3 in un assetto predefinito, dall’elemento centrale 2 sporgono due viti 7 contro le quali vanno in battuta detti bracci 1 e 3 in prossimità dei loro incemieramenti in 2; è pertanto possibile regolare l'inclinazione e scegliere l'assetto d’impiego di detti bracci semplicemente agendo sulle viti 7 contro le quali poggiano con la loro faccia interna, spinti dai martinetti 4 e 5. In order to allow the arms 1 and 3 to be stopped in a predefined position, two screws 7 protrude from the central element 2 against which said arms 1 and 3 abut near their hinges in 2; it is therefore possible to adjust the inclination and choose the position of use of said arms simply by acting on the screws 7 against which they rest with their internal face, pushed by the jacks 4 and 5.

Ad esempio, la FIG. 2 mostra il perfetto allineamento dei bracci 1 e 3 mentre le FIGG. 4 e 5 ne mostrano alcuni possibili assetti inclinati ottenuti avvitando oppure svitando maggiormente le viti di battuta 7; la FIG. 6 mostra invece come, al superamento dell’allineamento dei tre punti d’incernieramento suddetti, ma da parte opposta a quella d’azione delle viti 7, i due bracci 1 e 3 vadano in battuta contro lo stesso elemento centrale 2, risultando in tal caso reciprocamente paralleli. For example, FIG. 2 shows the perfect alignment of the arms 1 and 3 while FIGS. 4 and 5 show some possible inclined arrangements obtained by screwing or unscrewing the stop screws 7 more; FIG. 6 shows instead how, when the alignment of the three aforementioned hinging points is exceeded, but on the opposite side to that of the screws 7, the two arms 1 and 3 abut against the same central element 2, resulting in this mutually parallel case.

Dai bracci esterni 1 e 3 si protendono lateralmente le ali rigide 1A e 3A contro le quali fissare, grazie ai fori per le apposite viti, sia la struttura del mobile che la struttura della parte da movimentare. From the external arms 1 and 3 the rigid wings 1A and 3A extend laterally against which to fix, thanks to the holes for the appropriate screws, both the structure of the furniture and the structure of the part to be moved.

Inoltre, dovendo essere utilizzati a coppie, i meccanismi sono reciprocamente collegati da un traverso rigido 6 applicato agli elementi intermedi 2 di ciascun meccanismo. Furthermore, since the mechanisms must be used in pairs, they are mutually connected by a rigid crosspiece 6 applied to the intermediate elements 2 of each mechanism.

Resta infine da aggiungere che il meccanismo ideato, ferme restando le caratteristiche di massima illustrate e descritte, potrà essere suscettibile di modifiche o varianti che, comunque comprese nel presente ambito brevettale, potrebbero tra l’altro dipendere dalle caratteristiche strutturali e/o estetiche del mobile interessato come pure dalla conformazione e/o dalla collocazione della parte da movimentare, sia essa un poggiatesta, un poggiagambe, un bracciolo od altro. Finally, it remains to add that the devised mechanism, without prejudice to the general characteristics illustrated and described, may be susceptible to modifications or variations which, however included in the present patent scope, could, among other things, depend on the structural and / or aesthetic characteristics of the furniture. affected as well as by the conformation and / or by the location of the part to be moved, be it a headrest, a legrest, an armrest or other.
