Titolo: ?DISPOSITIVO DI GIUNZIONE A CONNESSIONE AUTOMATICA PER PARTI DI MOBILI? Title: ?SELF-CONNECTING JOINTING DEVICE FOR FURNITURE PARTS?
DESCRIZIONE DESCRIPTION
La presente invenzione ha per oggetto un dispositivo di giunzione a connessione automatica per parti di mobili e complementi di arredo, quali scaffali, librerie, cassettiere e simili. The present invention relates to an automatic connection joining device for parts of furniture and furnishing accessories, such as shelves, bookcases, chests of drawers and the like.
In particolare, la presente invenzione si riferisce a un dispositivo di giunzione idoneo ad assemblare le pareti laterali o montanti o spalle alla base e al top o cappello di un mobile, realizzando cos? la struttura del telaio del mobile. In particular, the present invention refers to a joining device suitable for assembling the side walls or uprights or shoulders to the base and top or cap of a piece of furniture, thus creating the structure of the frame of the furniture.
I dispositivi di giunzione noti per gli scopi suddetti sono normalmente realizzati in materiale metallico e comprendono bussole o eccentrici inseriti nello spessore della base e top e cooperanti in serraggio con corrispondenti perni o viti inseriti nei montanti, o viceversa, e che azionati a mezzo di un opportuno utensile (cacciavite o chiave a brugola o simile) determinano la rotazione della bussola o dell?eccentrico cos? da realizzare il vincolo di detto perno o vite rispetto a detta bussola o eccentrico. The known joining devices for the above-mentioned purposes are normally made of metal material and include bushings or eccentrics inserted in the thickness of the base and top and cooperating in tightening with corresponding pins or screws inserted in the uprights, or vice versa, and which, when operated by means of a suitable tool (screwdriver or Allen key or similar), determine the rotation of the bushing or eccentric so as to create the constraint of said pin or screw with respect to said bushing or eccentric.
Tuttavia, questi mezzi di serraggio o vincolo comportano alcuni inconvenienti di rilievo legati alla necessit? di dover utilizzare un utensile per agire sulla vite o perno per realizzare il serraggio. Inoltre, tali mezzi di serraggio comportano operazioni laboriose e tempi pi? lunghi di montaggio. However, these means of tightening or constraint involve some significant inconveniences related to the need to use a tool to act on the screw or pin to achieve the tightening. Furthermore, these means of tightening involve laborious operations and longer assembly times.
Per risolvere almeno in parte tali inconvenienti sono state sviluppate altre modalit? di giunzione, anche in materiale plastico, comprendenti una coppia di elementi che normalmente si accoppiano in modo inamovibile tra loro, per cui, in caso di necessit? di smontaggio del mobile, non sono recuperabili e vanno distrutti. To at least partially resolve these problems, other joining methods have been developed, even in plastic material, comprising a pair of elements that normally couple together in an immovable way, so that, in the event of the need to dismantle the furniture, they cannot be recovered and must be destroyed.
Scopo dell?invenzione ? quello di eliminare gli inconvenienti dei dispositivi di giunzione noti sopra descritti. The aim of the invention is to eliminate the drawbacks of the known joining devices described above.
In particolare, uno scopo dell?invenzione ? quello di fornire un dispositivo di giunzione per parti di mobili che sia economico e di semplice e rapido assemblaggio. In particular, an object of the invention is to provide a joining device for furniture parts that is economical and easy and quick to assemble.
Altro scopo dell?invenzione ? quello di fornire un tale dispositivo di giunzione che consenta una connessione pressoch? automatica. Another purpose of the invention is to provide such a joining device which allows for an almost automatic connection.
Altro scopo ancora dell?invenzione ? quello di fornire un tale dispositivo di giunzione che sia altamente affidabile, garantendo un ottimo serraggio tra le parti da assemblare senza rischi di allentamento. Another aim of the invention is to provide such a joining device that is highly reliable, ensuring excellent tightening between the parts to be assembled without the risk of loosening.
Ulteriore scopo dell?invenzione ? quello di fornire un tale dispositivo di giunzione che sia, all?occorrenza, smontabile e recuperabile, senza che venga danneggiato. A further aim of the invention is to provide such a joining device which can be dismantled and recovered if necessary without being damaged.
Questi scopi sono raggiunti dal dispositivo secondo l?invenzione che presenta le caratteristiche dell?annessa rivendicazione indipendente 1. These objectives are achieved by the device according to the invention which presents the characteristics of the attached independent claim 1.
Realizzazioni vantaggiose dell?invenzione sono espresse nelle rivendicazioni dipendenti. Advantageous embodiments of the invention are set forth in the dependent claims.
Sostanzialmente, il dispositivo di giunzione per parti di mobili, secondo l?invenzione, comprende una spina, fissabile in un foro di una parete laterale o spalla del mobile, e un inserto o bussola fissabile in un foro della base/top del mobile, in cui detta spina comprende un gambo sostanzialmente cilindrico, prolungantesi, da un lato con un tratto lavorato a vite per un montaggio autobloccante nella spalla del mobile e, dall?altro lato, con una linguetta presentante almeno un fianco seghettato, e in cui detto inserto ha una forma tubolare cava con un tratto iniziale cilindrico, rivolto verso la spina, prolungantesi, dal lato opposto, con due ali contrapposte a profilo circolare, tra le quali si determina un?apertura, all?interno della quale sono previste due alette contrapposte, disposte su piani paralleli al piano di detta linguetta e sviluppantisi dal tratto cilindrico, almeno una delle quali presentando un fianco interno seghettato atto ad impegnarsi con detto almeno un fianco seghettato della linguetta della spina per determinare un accoppiamento irreversibile tra tali componenti. Essentially, the joining device for furniture parts, according to the invention, comprises a pin, which can be fixed in a hole in a side wall or shoulder of the furniture, and an insert or bush which can be fixed in a hole in the base/top of the furniture, wherein said pin comprises a substantially cylindrical stem, extending, on one side with a screw-worked section for self-locking assembly in the shoulder of the furniture and, on the other side, with a tongue having at least one serrated side, and wherein said insert has a hollow tubular shape with an initial cylindrical section, facing the pin, extending, on the opposite side, with two opposing wings with a circular profile, between which an opening is created, inside which two opposing fins are provided, arranged on planes parallel to the plane of said tongue and developing from the cylindrical section, at least one of which has a serrated internal side capable of engaging with said at least one serrated side of the tongue of the pin to determine an irreversible coupling between said components.
Ulteriori caratteristiche dell?invenzione risulteranno pi? chiare dalla descrizione dettagliata che segue, riferita ad una sua forma puramente esemplificativa e quindi non limitativa di realizzazione, illustrata nei disegni annessi, in cui: Further features of the invention will become clearer from the detailed description that follows, referring to a purely exemplary and therefore non-limiting embodiment thereof, illustrated in the attached drawings, in which:
la figura 1 ? una vista in esploso assonometrico del dispositivo di giunzione di parti di mobili della presente invenzione, mostrante i due elementi che lo compongono in fase connessione; Figure 1 is an exploded isometric view of the furniture joining device of the present invention, showing the two elements that compose it in the connection phase;
la figura 2 ? una vista come quella di figura 1, in cui i due componenti sono parzialmente connessi tra loro; Figure 2 is a view like Figure 1, where the two components are partially connected to each other;
la figura 3 ? una vista come quella di figura 1, in cui i due componenti sono interamente connessi tra loro; Figure 3 is a view like Figure 1, where the two components are fully connected to each other;
la figura 4 ? una vista in esploso come quella di figura 1 in cui i due componenti sono ruotati di 180? e orientati in direzione opposta; Figure 4 is an exploded view like that of Figure 1 where the two components are rotated 180° and oriented in opposite directions;
le figure 5 e 6 sono viste in esploso, prese da direzioni opposte, mostranti il dispositivo in fase di montaggio tra le parti di mobile da collegare insieme; Figures 5 and 6 are exploded views, taken from opposite directions, showing the device being assembled between the furniture parts to be connected together;
Con riferimento a tali figure, il dispositivo di giunzione per parti di mobili secondo l?invenzione, indicato nel suo complesso con il numero di riferimento 1, comprende una spina 20, fissabile in un foro 4 di una parete laterale o spalla 2 del mobile, e un inserto o bussola 30 fissabile in un foro 5 della base o del top o cappello 3 del mobile, tra loro collegabili in modo amovibile, come sar? detto in seguito. With reference to these figures, the joining device for furniture parts according to the invention, indicated as a whole with the reference number 1, comprises a pin 20, fixable in a hole 4 of a side wall or shoulder 2 of the furniture, and an insert or bush 30 fixable in a hole 5 of the base or top or cap 3 of the furniture, which can be removably connected to each other, as will be explained later.
In particolare, la spina 20 comprende un gambo sostanzialmente cilindrico 21, prolungantesi, da un lato con un tratto lavorato a vite 22 per un montaggio autobloccante nella spalla del mobile ed eventuale smontaggio e, dall?altro lato, con una linguetta 23 presentante un fianco seghettato 24 e un fianco liscio 25, e un?estremit? smussata 26, per gli scopi che saranno detti in seguito. In particular, the pin 20 comprises a substantially cylindrical stem 21, extending, on one side with a screw-worked section 22 for self-locking assembly in the furniture shoulder and possible disassembly and, on the other side, with a tongue 23 having a serrated side 24 and a smooth side 25, and a bevelled end 26, for the purposes which will be described later.
Sul gambo 21 sono altres? previsti due piani o sfaccettature contrapposte 27 per l?eventuale smontaggio della spina dalla spalla del mobile. On the stem 21 there are also two opposing planes or facets 27 for the possible removal of the pin from the side of the furniture.
L?inserto 30 ha una forma tubolare cava con un tratto iniziale cilindrico 31, rivolto verso la spina 20, dove presenta un bordo anulare o colletto 32 atto ad andare in battuta contro il bordo della base o del top del mobile, determinando cos? la sua massima profondit? di inserimento. The insert 30 has a hollow tubular shape with a cylindrical initial section 31, facing the pin 20, where it has an annular edge or collar 32 designed to abut against the edge of the base or top of the piece of furniture, thus determining its maximum insertion depth.
Dal lato opposto al colletto 32, il tratto cilindrico cavo 31 si prolunga con due ali contrapposte 33 a profilo circolare, lavorate a vite per un montaggio autobloccante nella base o nel top del mobile. On the opposite side to the collar 32, the hollow cylindrical section 31 extends with two opposing wings 33 with a circular profile, machined with screws for self-locking assembly in the base or top of the furniture.
Le due ali 33 terminano con blocchetti semicilindrici o semiconici (nel seguito chiamati anche terminali) 34, separati da una fenditura assiale 35, che si dispone in un piano verticale ad assemblaggio avvenuto, comunicante con un?apertura interna pi? ampia 36, tra le due ali 33. The two wings 33 end with semi-cylindrical or semi-conical blocks (hereinafter also called terminals) 34, separated by an axial slit 35, which is arranged in a vertical plane after assembly, communicating with a larger internal opening 36, between the two wings 33.
All?interno di detta apertura 33 sono previste due alette contrapposte 37, 38, sviluppantisi dal tratto cilindrico 31, disposte su piani verticali. Inside said opening 33 there are two opposing fins 37, 38, developing from the cylindrical section 31, arranged on vertical planes.
L?aletta 37 ? a profilo liscio e ha uno spessore maggiore dell?aletta 38, in modo da risultare sostanzialmente rigida e fungere da piano di scorrimento per il fianco liscio 25 della linguetta 23 della spina 20. The fin 37 has a smooth profile and is thicker than the fin 38, so that it is substantially rigid and acts as a sliding surface for the smooth side 25 of the tongue 23 of the pin 20.
L?aletta 38 ? invece flessibile ed ha il fianco interno seghettato 39 in senso contrario alla seghettatura del corrispondente fianco 24 della linguetta 23 della spina 20, e termina con un prolungamento 40, oltre tale seghettatura e l?estremit? dell?aletta liscia 37. The fin 38 is flexible and has a serrated internal side 39 in the opposite direction to the serration of the corresponding side 24 of the tongue 23 of the pin 20, and ends with an extension 40, beyond this serration and the end of the smooth fin 37.
Descritta sinteticamente la struttura dei due componenti del dispositivo di giunzione secondo l?invenzione, il suo funzionamento risulta abbastanza intuitivo. Having briefly described the structure of the two components of the joining device according to the invention, its operation is quite intuitive.
La spina 20 viene inserita, eventualmente per avvitamento, con il suo tratto seghettato 22, nel foro 4 della spalla 2, facendo in modo che le due sfaccettature piane 27 del gambo 21 siano disposte orizzontalmente, con la linguetta 23 orientata verticalmente. The pin 20 is inserted, possibly by screwing, with its serrated section 22, into the hole 4 of the shoulder 2, ensuring that the two flat facets 27 of the shank 21 are arranged horizontally, with the tongue 23 oriented vertically.
L?inserto 30 viene invece inserito nel corrispondente foro 5 ricavato nella base o nel top 3 del mobile, fino a portare il colletto 32 in battuta con il suo bordo, con l?apertura 36 rivolta verso l?alto e le alette interne 37 e 38 disposte in modo da ricevere le corrispondenti facce liscia 25 e seghettata 24 della linguetta 23. The insert 30 is instead inserted into the corresponding hole 5 obtained in the base or top 3 of the piece of furniture, until the collar 32 is brought into contact with its edge, with the opening 36 facing upwards and the internal fins 37 and 38 arranged in such a way as to receive the corresponding smooth faces 25 and serrated faces 24 of the tongue 23.
La spalla 2 viene avvicinata alla base/ top 3, facendo in modo che la linguetta 23 e almeno parte del gambo cilindrico 21 della spina 20 si inseriscano nella cavit? tubolare dell?inserto 30. The shoulder 2 is brought closer to the base/top 3, causing the tongue 23 and at least part of the cylindrical stem 21 of the pin 20 to fit into the tubular cavity of the insert 30.
La figura 2 mostra una fase di inserimento intermedia, in cui le seghettature 24 e 39 sono parzialmente impegnate tra loro, ma l?estremit? smussata 26 della linguetta 23 non ha ancora raggiunto i terminali 34 delle ali 33 dell?inserto 30. Figure 2 shows an intermediate insertion phase, in which the serrations 24 and 39 are partially engaged with each other, but the beveled end 26 of the tab 23 has not yet reached the ends 34 of the wings 33 of the insert 30.
Premendo con forza la spina 20 nell?inserto 30, ovvero la spalla 2 contro la base/ top 3, l?estremit? smussata 26 della linguetta 23 entra nella fenditura 35 tra i terminali 34, provocandone il distanziamento, ovvero l?espansione delle ali contrapposte lavorate a vite 33, che si impegnano saldamente nel foro 5 della base/ top 3, bloccando l?inserto 30 in esso. By forcefully pressing the pin 20 into the insert 30, i.e. the shoulder 2 against the base/top 3, the chamfered end 26 of the tab 23 enters the slot 35 between the terminals 34, causing them to move apart, i.e. the expansion of the opposite screw-worked wings 33, which engage firmly in the hole 5 of the base/top 3, locking the insert 30 in it.
Durante questa operazione, le seghettature 24 e 39 della spina 20 e del top 30, incastrandosi, rendono di fatto il bloccaggio tra i due componenti irreversibile. During this operation, the serrations 24 and 39 of the pin 20 and of the top 30, interlocking, effectively make the locking between the two components irreversible.
In alternativa a quanto esposto, il dispositivo pu? essere fornito parzialmente preassemblato, con la spina 2 parzialmente inserita nell?inserto 3. L?inserto con la spina premontata viene quindi inserito nel foro 5 della base/top 3, e quindi la spalla 2, disposta con il suo foro a in allineamento con la spina 20, viene spinta contro la base/top (30), provocando l?accoppiamento. Alternatively to the above, the device can be supplied partially pre-assembled, with the pin 2 partially inserted into the insert 3. The insert with the pre-assembled pin is then inserted into the hole 5 of the base/top 3, and then the shoulder 2, arranged with its hole a in alignment with the pin 20, is pushed against the base/top (30), causing the coupling.
Nella base/top 3 ? previsto un foro verticale 6 che si dispone in corrispondenza dell?apertura 36 dell?inserto 3, e precisamente in corrispondenza del prolungamento 40 dell?aletta 38, attraverso il quale ? possibile inserire la punta di un cacciavite per distanziare l?aletta 38 dalla linguetta 23, provocando il distacco delle rispettive seghettature, rendendo possibile il disaccoppiamento della spina 20 dall?inserto 30. Pertanto tali componenti risultano accoppiati in modo amovibile. In the base/top 3 there is a vertical hole 6 which is positioned in correspondence with the opening 36 of the insert 3, and precisely in correspondence with the extension 40 of the fin 38, through which it is possible to insert the tip of a screwdriver to distance the fin 38 from the tab 23, causing the detachment of the respective serrations, making it possible to uncouple the pin 20 from the insert 30. Therefore these components are coupled in a removable manner.
Successivamente ? possibile estrarre la spina 20 dalla spalla 2, agendo con una chiave sulle sfaccettature contrapposte 27 previste sul suo gambo 21, ed eventualmente anche l?inserto 30, estraendolo dal corrispondente foro. Subsequently, it is possible to extract the pin 20 from the shoulder 2, by acting with a key on the opposite facets 27 provided on its stem 21, and possibly also the insert 30, by extracting it from the corresponding hole.
Da quanto esposto appaiono evidenti i vantaggi del dispositivo di giunzione per parti di mobili secondo l?invenzione, costituito da due soli componenti in materiale plastico, che consentono una connessione pressoch? automatica, determinante un accoppiamento irreversibile, tuttavia con possibilit? di smontaggio e recupero dei componenti. From what has been set out, the advantages of the joining device for furniture parts according to the invention are evident, consisting of only two plastic components, which allow for an almost automatic connection, determining an irreversible coupling, however with the possibility of dismantling and recovering the components.
Naturalmente l?invenzione non ? limitata alla particolare forma di realizzazione precedentemente descritta ed illustrata nei disegni annessi, ma ad essa possono essere apportate numerose modifiche di dettaglio alla portata del tecnico del ramo, senza per questo uscire dall?ambito dell?invenzione stessa, come definito dalle rivendicazioni annesse. Naturally, the invention is not limited to the particular embodiment previously described and illustrated in the attached drawings, but numerous modifications of detail within the scope of the technician in the field can be made to it, without departing from the scope of the invention itself, as defined by the attached claims.
