“TRAVE COMPOSITA A FLESSIONE CONTROLLATA PER ARREDO DEL TIPO COMPONIBILE†⠀ œCOMPOSIT BEAM WITH CONTROLLED BENDING FOR FURNITURE OF THE COMPONABLE TYPEâ €
La presente invenzione si riferisce ad un trave composita a flessione controllata per arredo del tipo componibile. The present invention refers to a composite beam with controlled bending for furniture of the modular type.
Il campo dell’invenzione à ̈ in generale quello delle camere per ragazzi, nella progettazione delle quali le esigenze legate allo sfruttamento ottimale dello spazio spingono i progettisti a trovare particolari soluzioni nella.creazione di mobili componibili. The field of invention is in general that of children's rooms, in the design of which the needs linked to the optimal use of space push designers to find particular solutions in the creation of modular furniture.
Il brevetto italiano N. 1359542 della stessa Richiedente descrive un profilato in lega leggera avente un profilo esterno comprendente, come fianchi laterali, rami di un’ellisse parziale le cui estremità sono congiunte da un lato piatto ottenuto con l’intersezione di un piano ortogonale al piano di simmetria del profilo contenente l’asse maggiore dell’ellisse. Una scanalatura a coda di rondine à ̈ ricavata nel lato piatto del profilo esterno. Una parete interna perpendicolare al lato piatto, contenente il piano di simmetria del profilo, termina con due ringrossi di estremità , in cui sono ricavati fori passanti per viti di fissaggio. Le viti di fissaggio servono, ad esempio, a collegare di testa un’estremità del profilato con un pannello ortogonale al profilato stesso, oppure ad un altro profilato. The Italian patent No. 1359542 of the same Applicant describes a light alloy profile having an external profile comprising, as lateral sides, branches of a partial ellipse whose ends are joined by a flat side obtained with the intersection of a plane orthogonal to the symmetry plane of the profile containing the major axis of the ellipse. A dovetail groove is obtained in the flat side of the external profile. An internal wall perpendicular to the flat side, containing the symmetry plane of the profile, ends with two end pads, in which pass-through holes for fixing screws are obtained. The fixing screws are used, for example, to connect one end of the profile with a panel perpendicular to the profile itself, or to another profile.
La particolare conformazione del profilato studiata dalla Richiedente funziona egregiamente. Tuttavia, la parete interna giacente nel piano di simmetria non à ̈ sufficiente a conferire al profilato la rigidezza richiesta quando deve funzionare da trave di sostegno. Infatti, quando la trave di sostegno, appoggiata generalmente alle estremità , à ̈ sottoposta a carichi, tende a flettersi. La flessione può anche essere The particular shape of the section studied by the Applicant works very well. However, the internal wall lying in the plane of symmetry is not sufficient to give the profile the required stiffness when it has to function as a support beam. In fact, when the support beam, generally supported at the ends, is subjected to loads, it tends to flex. Flexion can also be
non completamente piano. not completely flat.
Quindi, sia nei casi in cui la trave di sostegno à ̈ sollecitata, sia nei casi in cui non sia perfettamente appoggiata, si crea la necessità di farla lavorare in modo corretto e anche di evitare avvallamenti e deformazioni esteticamente non accettabili. Therefore, both in cases in which the support beam is stressed and in cases in which it is not perfectly supported, there is the need to make it work correctly and also to avoid aesthetically unacceptable depressions and deformations.
D’altro canto à ̈ noto che esistono travi composite, cioà ̈ realizzate con materiali che di per sé non sarebbero in grado di resistere alla flessione, e quindi sono combinati con altri elementi di materiale diverso per una aumentata rigidezza. On the other hand, it is known that composite beams exist, that is, made with materials that in themselves would not be able to resist bending, and therefore are combined with other elements of different material for increased stiffness.
Pertanto, uno scopo della presente invenzione à ̈ quello fornire una trave composita capace di resistere egregiamente a carichi di flessione anche se realizzata in generale con materiali che non sarebbero in grado di farlo. In particolare, uno scopo dell’invenzione à ̈ quello di fornire una particolare combinazione e disposizione di componenti interni ad una trave realizzata con un profilato-in lega leggera di profilo noto, in maniera che possa essere regolata la sua flessione. Therefore, an object of the present invention is to provide a composite beam capable of withstanding bending loads very well even if made in general with materials that would not be able to do so. In particular, an object of the invention is to provide a particular combination and arrangement of components internal to a beam made with a light alloy profile of known profile, so that its bending can be adjusted.
Un ulteriore scopo dell’invenzione à ̈ quello di consentire anche ad un utilizzatore una regolazione semplice ed efficace della flessione secondo le esigenze del momento. A further object of the invention is to allow even a user a simple and effective adjustment of the flexion according to the needs of the moment.
Ancora un altro scopo dell’invenzione à ̈ quello di consentire ad una trave di profilo noto di mantenere esternamente lo stesso aspetto pur avendo notevolmente aumentato la sua resistenza alla flessione. Yet another object of the invention is to allow a beam with a known profile to maintain the same appearance externally while having considerably increased its resistance to bending.
Pertanto, l’invenzione fornisce una trave a flessione controllata per arredo del tipo componibile, come caratterizzata nella rivendicazione 1 e nelle rivendicazioni da essa dipendenti. Therefore, the invention provides a controlled bending beam for furniture of the modular type, as characterized in claim 1 and in the claims dependent on it.
La presente invenzione verrà descritta con riferimento ad una sua forma preferita di realizzazione, considerata unitamente al disegno allegato, in cui: la figura 1 à ̈ una sezione trasversale di un profilato con cui à ̈ realizzata una trave composita a flessione controllata per arredo del tipo componibile secondo l’invenzione; The present invention will be described with reference to a preferred embodiment thereof, considered together with the attached drawing, in which: Figure 1 is a cross section of a profile with which a composite beam with controlled bending for furniture of the type is made modular according to the invention;

la figura 6 Ã ̈ una vista prospettica sezionata come nella figura 5. figure 6 is a sectional perspective view as in figure 5.
Facendo riferimento alla figura 1, in essa à ̈ mostrato in sezione trasversale un profilato 10 in lega leggera per un trave a flessione controllata per arredo del tipo componibile secondo la presente invenzione. With reference to Figure 1, it shows in cross section a section 10 in light alloy for a beam with controlled flexion for furniture of the modular type according to the present invention.
Come mostrato nella Figura 1, la sezione del profilato 10 à ̈ parzialmente ellittica. Infatti essa comprende un profilo esterno con fianchi laterali 1, 2 che sono rami di un’ellisse avente un asse maggiore y. L’asse maggiore y dell’ellisse à ̈ contenuto nel piano di simmetria del profilo. Un lato piatto 3 à ̈ ortogonale al piano di simmetria del profilo. As shown in Figure 1, the section of the profile 10 is partially elliptical. In fact it comprises an external profile with lateral sides 1, 2 which are branches of an ellipse having a major axis y. The major y axis of the ellipse is contained in the symmetry plane of the profile. A flat side 3 is orthogonal to the symmetry plane of the profile.
Nel lato piatto 3 del profilo à ̈ ricavata una scanalatura 4 a coda di rondine. In internamente ai fianchi 1, 2 sono sporgenti contrapposte porzioni circolari cave aperte 5, 6, funzionanti da sedi per viti. Infatti, le porzioni circolari cave aperte 5, 6 sono destinate a ricevere nei loro fori passanti rispettive viti autofilettanti di fissaggio di un coperchio come si vedrà in seguito. In the flat side 3 of the profile there is a dovetail groove 4. Inside the flanks 1, 2 opposing open circular hollow portions 5, 6 protrude, functioning as seats for screws. In fact, the open hollow circular portions 5, 6 are intended to receive in their through holes respective self-tapping screws for fixing a cover as will be seen below.
Nella scanalatura 4 a coda di rondine sono impegnati tasselli (non mostrati) per il collegamento del profilato 10 con un piano di appoggio, anch’esso non mostrato. In the dovetail groove 4 there are plugs (not shown) for the connection of the profile 10 with a support surface, also not shown.
Nella figura 2 à ̈ mostrato in vista frontale un organo pressore 7 conformato almeno parzialmente secondo il profilo interno del profilato 10. In particolare, l’organo pressore, che ha pareti laterali 8 e 9 conformi ai fianchi 1 e 2 ad ellisse del profilato 10 presenta gole 11, 12 destinate a circondare le porzioni circolari cave aperte 5, 6 sporgenti internamente dai fianchi 1 e 2 del profilato 10. Sulle estremità opposte dell’elemento pressore 7 lungo l’asse y sono rientranze 13, 14, ognuna fungente da sede di alloggiamento e di guida per un tirante come si vedrà nel seguito. Figure 2 shows a front view of a pressure element 7 shaped at least partially according to the internal profile of the section 10. In particular, the pressure element, which has side walls 8 and 9 conforming to the elliptical sides 1 and 2 of the section 10 has grooves 11, 12 intended to surround the open circular hollow portions 5, 6 projecting internally from the sides 1 and 2 of the section 10. On the opposite ends of the pressure element 7 along the y axis there are recesses 13, 14, each acting as housing and guide seat for a tie rod as will be seen below.
L’organo pressore 7 à ̈ fatto preferibilmente di una materia plastica sufficientemente rigida, come ABS. Per aumentare la sua rigidezza, sono previsti risalti periferici indicati complessivamente con 15 e nervature dirette secondo assi ortogonali 16. The pressure member 7 is preferably made of a sufficiently rigid plastic material, such as ABS. To increase its stiffness, peripheral projections indicated as a whole with 15 and ribs directed along orthogonal axes 16 are provided.
Nella figura 3 à ̈ mostrata, in vista prospettica, un coperchio indicato con 17 del profilato 10 della figura 1. Il coperchio 17 à ̈ conformato esternamente per andare a battuta al profilato 10 come mostrato nella figura 4, che à ̈ una vista prospettica in esploso che mostra una trave composita a flessione controllata per arredo del tipo componibile ottenuta con il profilato della figura 1. Il coperchio 17, realizzato con un qualunque materiale di adeguata rigidezza, à ̈ dotato di una serie di fori passanti, includenti un primo foro passante 18 per la regolazione di un tirante, come si vedrà nel seguito, secondi fori passanti 19, 20 per il fissaggio del coperchio 17 al profilato 10 mediante viti autofilettanti (non mostrate) avvitate nelle porzioni circolari cave aperte 5, 6 sporgenti internamente dai fianchi 1 e 2 del profilato 10, e terzi fori passanti 21, 22 per il fissaggio della trave secondo la presente invenzione ad una porzione strutturale S mediante viti 23, come mostrato nella figura 4. In questa figura sono mostrate sostanzialmente tutti i componenti sopra citati, vale a dire il profilato 10, gli organi pressori 7, i coperchi 17 ed inoltre un tirante 24, sotto forma di un tondino filettato almeno nelle sue estremità opposte, una cooperante boccola filettata 25, ad esempio a testa esagonale ribassata, ed un elemento copri boccola 26. L’elemento copri boccola 26 ha una funzione estetica per coprire un relativo foro praticato nella porzione struttura S, quale ad esempio un pannello, e nello stesso tempo porta indicazioni per mostrare all’utilizzatore in che verso debba ruotare la boccola filettata per mettere in trazione il tirante 7 Tuttavia, quest’ultima operazione risulterà maggiormente chiara nella descrizione che segue, con riferimento alle figure 5 e 6, che sono una sezione longitudinale tagliata della trave composita Figure 3 shows, in perspective view, a cover indicated with 17 of profile 10 of figure 1. The cover 17 is shaped externally to abut against profile 10 as shown in figure 4, which is a perspective view in exploded view showing a composite beam with controlled flexion for furniture of the modular type obtained with the profile of figure 1. The cover 17, made with any material of adequate stiffness, is equipped with a series of through holes, including a first through hole 18 for adjusting a tie rod, as will be seen below, second through holes 19, 20 for fixing the cover 17 to the profile 10 by means of self-tapping screws (not shown) screwed into the open hollow circular portions 5, 6 protruding internally from the sides 1 and 2 of the section 10, and third through holes 21, 22 for fixing the beam according to the present invention to a structural portion S by means of screws 23, as shown in figure 4. In this figure substantially all the components mentioned above are shown, namely the section 10, the pressure elements 7, the covers 17 and also a tie rod 24, in the form of a threaded rod at least in its opposite ends, one cooperating threaded bush 25, for example with a lowered hexagonal head, and a bush cover element 26. The bush cover element 26 has an aesthetic function to cover a relative hole made in the structure portion S, such as for example a panel, and in the same time brings indications to show the user in which direction the threaded bushing must rotate to put the tie rod in traction 7 However, this last operation will become clearer in the following description, with reference to figures 5 and 6, which are a longitudinal section of the composite beam
ottenuta con un piano verticale centrale e, rispettivamente, una vista prospettica della stessa trave composita sezionata. obtained with a central vertical plane and, respectively, a perspective view of the same composite sectioned beam.
Come si può vedere nelle figure 5 e 6, il tirante 24 à ̈ inserito dentro il profilato 10, facendolo passare nella sede 13 di alloggiamento e di guida ottenuta con la rientranza nell’organo pressore 7 disposto centralmente nella trave. Il tirante 24, alle sue estremità opposte, à ̈ avvitato parzialmente nelle rispettive boccole filettate 25. Se l’utilizzatore avvita o svita le boccole filettate 25, facendole ruotare con una chiave esagonale (non mostrata), sul tirante 24 à ̈ applicata più o meno trazione, che si trasmette sull’organo pressore 7 e da questo sul profilato 10, per controllare, cioà ̈ modificare, la flessione della trave, vale a dire la sua freccia centrale. As can be seen in figures 5 and 6, the tie rod 24 is inserted inside the profile 10, making it pass into the housing and guide seat 13 obtained with the recess in the pressure member 7 arranged centrally in the beam. The tie rod 24, at its opposite ends, is partially screwed into the respective threaded bushings 25. If the user screws or unscrews the threaded bushings 25, turning them with a hex wrench (not shown), more or less traction, which is transmitted on the pressure member 7 and from this on the profile 10, to control, that is to say, to modify the bending of the beam, that is to say its central arrow.
Gli organi pressori 7 di estremità possono essere utili a sostenere le boccole filettate 25 che a loro volta sono sottoposte a flessione determinata dal tirante 24 in cooperazione coll’organo pressore centrale. The end pressing members 7 can be useful for supporting the threaded bushings 25 which in turn are subjected to bending determined by the tie rod 24 in cooperation with the central pressing member.
II vantaggio principale della trave secondo l’invenzione consiste soprattutto nel fatto che essa consiste in un componente per arredo che non richiede, dopo il suo assemblaggio in fabbrica, alcuna altra operazione di montaggio, se non la sua applicazione nell’arredo a cui à ̈ destinata. The main advantage of the beam according to the invention consists above all in the fact that it consists of a component for furniture that does not require, after its assembly in the factory, any other assembly operation, other than its application in the furniture to which It is destined.
