Description
Forma oggetto del presente trovato un dispositivo di articolazione di schienali di sedie e simili al relativo telaio, comprendente almeno una spira di molla i cui opposti bracci sono rispettivamente solidali a detti schienale e telaio. The present invention relates to a device for articulating backrests of chairs and the like to the relative frame, comprising at least one coil of spring whose opposite arms are respectively integral with said backrest and frame.
E' nota nella tecnica di produzione di sedie e simili la necessità di rendere lo schienale delle stesse articolato rispetto al telaio al fine di rendere disponibili differenti inclinazioni dello schienale per un più confortevole appoggio. It is known in the production art of chairs and the like the need to make the backrest of the same articulated with respect to the frame in order to make available different inclinations of the backrest for a more comfortable support.
Sono anche noti alcuni esempi di articolazione per schienali di sedie, i quali pur funzionali allo scopo sono di struttura complessa e costosa e di aspetto estetico non integrato nello stile della sedia. Some examples of articulation for chair backs are also known, which, although functional for the purpose, have a complex and expensive structure and an aesthetic appearance that is not integrated into the style of the chair.
Si pone pertanto il problema tecnico di realizzare un dispositivo di articolazione per schienali di sedie che risulti strutturalmente semplice e affidabile, costituito da un ridotto numero di parti di facile assemblaggio e applicabile a qualunque tipo di sedia, poltroncina e simile con o senza braccioli. The technical problem therefore arises of providing an articulation device for chair backs which is structurally simple and reliable, consisting of a small number of parts which are easy to assemble and can be applied to any type of chair, small armchair and the like with or without armrests.
Nell'ambito di tale problema costituisce ulteriore necessità che l'articolazione presenti un certo grado di elasticità per consentire un leggero molleggio dello schienale. Within this problem, a further need is for the joint to have a certain degree of elasticity to allow a slight springing of the backrest.
Tali problemi tecnici sono risolti secondo il presente trovato da un dispositivo di articolazione di schienali di sedie e simili al relativo telaio, comprendente almeno una spira di molla i cui opposti bracci sono rispettivamente solidali a detti schienale e telaio. Maggiori dettagli potranno essere rilevati dalla seguente descrizione di un esempio non limitativo di attuazione del trovato effettuata con riferimento ai disegni allegati nei quali si mostra: These technical problems are solved according to the present invention by a device for articulating backrests of chairs and the like to the relative frame, comprising at least one coil of spring whose opposite arms are respectively integral with said backrest and frame. More details can be found from the following description of a non-limiting example of embodiment of the invention made with reference to the attached drawings which show:
in figura 1 : una vista prospettica parzialmente esplosa del dispositivo di articolazione secondo il trovato; in figure 1: a partially exploded perspective view of the articulation device according to the invention;
in figura 2 : una vista prospettica del dispositivo con schienale montato; in figure 2: a perspective view of the device with the backrest mounted;
in figura 3 : una sezione secondo un piano verticale del dispositivo montato: in figure 3: a section according to a vertical plane of the mounted device:
Come illustrato il dispositivo di articolazione secondo il trovato comprende due coppie di fili 1 di acciaio o simile materiale, ciascuno dei quali è attorto per formare una spira 2 di una molla con bracci 3 e 4 opposti, rispettivamente solidali al telaio 5 della sedia e ad un elemento di supporto 6 dello schienale 7 della sedia stessa. As illustrated, the articulation device according to the invention comprises two pairs of wires 1 of steel or similar material, each of which is twisted to form a coil 2 of a spring with opposite arms 3 and 4, respectively integral with the frame 5 of the chair and with a support element 6 of the backrest 7 of the chair itself.
Ciascun braccio 4 solidale allo schienale 7 è dotato di una filettatura 4a. Each arm 4 integral with the backrest 7 is provided with a thread 4a.
Detto elemento 6 di supporto dello schienale 7 presenta forma sostanzialmente ad "L" con ramo corto orizzontale dotato di un foro 6a per l'accoppiamento con la filettatura 4a del braccio 4 della molla, sul quale è bloccato tramite mezzi noti quali una saldatura o un grano trasversale 6b inserito nel ramo corto stesso, fino ad interagire con la filettatura 4a. Said element 6 supporting the backrest 7 has a substantially "L" shape with a short horizontal branch equipped with a hole 6a for coupling with the thread 4a of the arm 4 of the spring, on which it is blocked by known means such as a welding or a transversal grain 6b inserted in the short branch itself, until it interacts with the thread 4a.
Il ramo lungo 6c verticale dell'elemento di supporto 6 presenta un foro 6d di passaggio di una vite 8" di bloccaggio del supporto 6 dello schienale 7. The long vertical branch 6c of the support element 6 has a hole 6d for the passage of a screw 8 "for locking the support 6 of the backrest 7.
Il braccio 3 della molla inserito nel telaio 5 è a sua volta bloccato su quest'ultimo tramite un grano 5a trasversale. In corrispondenza del foro di ingresso del braccio 3 nel telaio 5 è inoltre disposta una bussola di guida 9. The arm 3 of the spring inserted in the frame 5 is in turn locked on the latter by means of a transverse grain 5a. A guide bush 9 is also arranged in correspondence with the entry hole of the arm 3 in the frame 5.
Sebbene descritta in una forma funzionalmente completa e strutturalmente di alta affidabilità, preferibile anche dal punto di vista estetico, il dispositivo potrebbe essere ridotto alla semplice spira con bracci 3 e 4 direttamente inseriti nel telaio 5 e nello schienale 7 senza necessità di elementi intermedi. Although described in a functionally complete and structurally highly reliable form, preferable also from an aesthetic point of view, the device could be reduced to a simple loop with arms 3 and 4 directly inserted in the frame 5 and in the backrest 7 without the need for intermediate elements.
