Description

“SCRIVANIA SOSPESA” "SUSPENDED DESK"

La presente invenzione si riferisce ad una scrivania sospesa provvista di innovativi sistemi di montaggio del ripiano ad una struttura di supporto e, nel contempo, di innovativi sistemi di regolazione per un corretto e sicuro ancoraggio a parete della struttura di supporto medesima, quindi della scrivania sospesa. La tendenza attuale della architettura d’interni è quella di realizzare ripiani di mobili che si estendono a sbalzo direttamente da una parete di supporto, così da avere completamente liberi gli spazi sottostante e sovrastante. The present invention refers to a suspended desk equipped with innovative systems for mounting the shelf to a support structure and, at the same time, with innovative adjustment systems for a correct and safe anchoring to the wall of the support structure itself, therefore of the suspended desk. . The current trend of interior architecture is to create furniture shelves that extend directly from a support wall, so as to have the spaces below and above completely free.

Questa esigenza è particolarmente sentita nella realizzazione di scrivanie sospese ove lo spazio sottostante è adibito all’alloggiamento di accessori vari ed al passaggio di cavi di servizio. This need is particularly felt in the construction of suspended desks where the space below is used for housing various accessories and for the passage of service cables.

Per questo motivo è altamente desiderabile che la scrivania sia completamente priva di spalle laterali, o di altri ingombranti mezzi di supporto equivalenti. For this reason it is highly desirable that the desk be completely free from side shoulders, or other bulky equivalent support means.

Una tale esigenza è soddisfatta dalle scrivanie il cui ripiano si estende a sbalzo direttamente da una parete di supporto. Such a need is satisfied by the desks whose shelf extends directly from a supporting wall.

Tuttavia, sono ben note le difficoltà oggettive per realizzare una struttura di supporto a sbalzo capace di supportare in maniera adeguata e sicura i carichi a cui il ripiano è sottoposto, carichi che sono estremamente variabili. Detti carichi, infatti, aumentano sensibilmente con l’aumentare della profondità del ripiano, in funzione del carico statico gravante su di esso, e delle sollecitazioni dinamiche trasmesse dall’utilizzatore, che possono essere estremamente variabili e molto gravose. However, the objective difficulties in realizing a cantilevered support structure capable of adequately and safely supporting the loads to which the shelf is subjected, loads which are extremely variable, are well known. These loads, in fact, increase significantly with increasing depth of the shelf, depending on the static load weighing on it, and the dynamic stresses transmitted by the user, which can be extremely variable and very heavy.

Una struttura di supporto a sbalzo per ripiani di mobili, in particolare scrivanie, oltre alle esigenze sopra esposte, dovrebbe anche consentire di montare il ripiano in una posizione corretta rispetto sia alla parete (non sempre perfettamente piana), che a ripiani adiacenti. A cantilevered support structure for furniture shelves, in particular desks, in addition to the above requirements, should also allow the shelf to be mounted in a correct position with respect to both the wall (not always perfectly flat) and adjacent shelves.

Occorre inoltre rilevare che, secondo l’arte nota, ad ogni profondità di ripiano a sbalzo, è dedicata una corrispondente misura di struttura di supporto, con una conseguente gestione del magazzino, che per il costruttore del mobile è complicata ed onerosa. It should also be noted that, according to the known art, a corresponding measure of the support structure is dedicated to each depth of the cantilevered shelf, with consequent management of the warehouse, which for the furniture manufacturer is complicated and expensive.

Scopo generale della presente invenzione è quello di risolvere i problemi sopra citati, realizzando una scrivania sospesa mediante una struttura di supporto a sbalzo atta ad essere fissata a parete, in una posizione precisa e corretta, così da supportare in maniera sicura anche carichi molto gravosi. The general purpose of the present invention is to solve the aforementioned problems, realizing a suspended desk by means of a cantilevered support structure able to be fixed to the wall, in a precise and correct position, so as to safely support even very heavy loads.

Un altro scopo della presente invenzione è quello di realizzare una struttura di supporto che sia facilmente adattabile a diverse profondità di ripiani della scrivania. Another object of the present invention is to provide a support structure which is easily adaptable to different depths of desk shelves.

Ulteriore scopo dell’invenzione è quello di realizzare una scrivania sospesa il cui ripiano sia facilmente accoppiabile alla struttura di supporto. A further purpose of the invention is to create a suspended desk whose shelf can be easily coupled to the support structure.

Gli scopi suddetti sono conseguiti da una scrivania sospesa mediante una struttura di supporto a sbalzo avente le caratteristiche esposte nella rivendicazione 1 allegata e sottorivendicazioni. The aforesaid objects are achieved by a desk suspended by means of a cantilevered support structure having the characteristics set out in the attached claim 1 and the subordinate claims.

Con riferimento ai disegni, la struttura di supporto a sbalzo per ripiani di mobili, secondo l’invenzione, particolarmente, ma non esclusivamente, per la realizzazione di scrivanie sospese, è complessivamente indicata con 10. With reference to the drawings, the cantilevered support structure for furniture shelves, according to the invention, particularly, but not exclusively, for the construction of suspended desks, is indicated as a whole with 10.

Detta struttura 10 comprende un montante 11 ed un braccio 12 estendentesi a sbalzo dall’estremità inferiore di detto montante 11. Said structure 10 comprises an upright 11 and an arm 12 extending cantilevered from the lower end of said upright 11.

Il montante 11, nell’esempio illustrato, ha sezione trasversale a C, le cui ali 13, all’estremità superiore, sono sagomate a guisa di gancio 14 per l’aggancio del montante 11 ad un elemento portante, ad esempio al bordo 15 di una piastra 16 (o altro elemento portante equivalente) fissata ad una parete 17. Invece della piastra 16 può anche essere prevista una barra continua. The upright 11, in the example illustrated, has a C-shaped cross section, the wings 13 of which, at the upper end, are shaped like a hook 14 for hooking the upright 11 to a bearing element, for example to the edge 15 of a plate 16 (or other equivalent bearing element) fixed to a wall 17. Instead of the plate 16, a continuous bar can also be provided.

Il montante 11, in corrispondenza di detta estremità superiore, è inoltre provvisto di un sistema di regolazione in verticale comprendente un grano 18 che agisce contro il bordo 15 della piastra 16 (figure 1 e 5). A tale fine il grano 18 si avvita attraverso un foro filettato 19 di una piattina 20 tenuta in posto tramite una molla a forcella 21. The upright 11, at said upper end, is also provided with a vertical adjustment system comprising a dowel 18 which acts against the edge 15 of the plate 16 (Figures 1 and 5). To this end, the dowel 18 is screwed through a threaded hole 19 of a strip 20 held in place by a fork spring 21.

Sempre in prossimità dell’estremità superiore, l’anima 22 del montante 11 presenta un foro filettato 23 attraversato da un grano 24. Detto grano 24 (figura 5), agendo contro il bordo 15 della piastra 16, ha la funzione di recuperare i giochi e di fissare in posizione il montante 11, dopo le varie regolazioni, come risulterà evidente nel seguito. Always near the upper end, the core 22 of the upright 11 has a threaded hole 23 crossed by a dowel 24. Said dowel 24 (figure 5), acting against the edge 15 of the plate 16, has the function of recovering the play and to fix the upright 11 in position, after the various adjustments, as will be evident in the following.

Il braccio 12, che può ad esempio essere cilindrico, è fissato al montante 11 tramite una vite 25 che si avvita attraverso un foro filettato assiale 26 del braccio 12 stesso (figure 1 e 5). The arm 12, which can be cylindrical for example, is fixed to the upright 11 by means of a screw 25 which is screwed through an axial threaded hole 26 of the arm 12 itself (Figures 1 and 5).

La stessa vite 25 blocca sull’anima 22 del montante 11 una piastrina verticale 27, interna al montante 11, ed una piastrina orizzontale esterna 28. A tal fine l’anima 22, e le piastrine 27, 28, presentano rispettivi fori 29, 30, 31 per il passaggio della vite 25 (figure 1 e 5). The same screw 25 locks on the core 22 of the upright 11 a vertical plate 27, internal to the upright 11, and an external horizontal plate 28. To this end, the core 22, and the plates 27, 28, have respective holes 29, 30 , 31 for the passage of the screw 25 (figures 1 and 5).

Sulla piastrina 27 è inoltre avvitata una vite 32 con testa circolare sporgente 33 atta ad agganciarsi, preferibilmente dall’alto, entro una sede sagomata 34 di un elemento portante, ad esempio una piastra 35 (o altro elemento portante equivalente) fissata alla parete 17 (figure 2, 4 e 5). Invece della piastra 35 può essere prevista una barra continua. On the plate 27 there is also screwed a screw 32 with a protruding circular head 33 suitable for hooking, preferably from above, into a shaped seat 34 of a bearing element, for example a plate 35 (or other equivalent bearing element) fixed to the wall 17 ( figures 2, 4 and 5). Instead of the plate 35, a continuous bar can be provided.

L’estremità libera di detta vite 32, opposta alla testa 33, presenta una sede di manovra sagomata 36, accessibile attraverso un foro 37 dell’anima 22, così da poter ruotare la vite 32 stessa attraverso un foro filettato 32a a scopo di recupero giochi e serraggio in posizione, analogamente al grano 24. The free end of said screw 32, opposite to the head 33, has a shaped operating seat 36, accessible through a hole 37 in the core 22, so as to be able to rotate the screw 32 itself through a threaded hole 32a for the purpose of recovering play and tightening in place, similar to the grain 24.

Attraverso fori filettati laterali 38 della piastrina 28 sono avvitati rispettivi grani 39 i quali, reagendo contro la piastra 35 fissata a parete, consentono di registrare la perpendicolarità del braccio 12 rispetto alla parete 17, su di un piano orizzontale, ed anche il parallelismo con i bracci 12 di altre strutture di supporto affiancate, (figure 7 e 8), come pure la messa in bolla (figure 4 e 6). Through the lateral threaded holes 38 of the plate 28 respective dowels 39 are screwed which, reacting against the plate 35 fixed to the wall, allow to record the perpendicularity of the arm 12 with respect to the wall 17, on a horizontal plane, and also the parallelism with the arms 12 of other supporting structures side by side (Figures 7 and 8), as well as leveling (Figures 4 and 6).

Con U sono indicati utensili di manovra dei grani 18, 24, 39 e della vite 36, e con B è schematizzata una bolla posizionata sul braccio 12 (figura 6). U denotes tools for maneuvering the grains 18, 24, 39 and the screw 36, and with B a bubble positioned on the arm 12 is schematised (Figure 6).

Il funzionamento ed il modo di impiego della struttura di supporto secondo l’invenzione sono chiari da quanto sopra descritto con riferimento alle figure ed in breve sono come segue. The operation and method of use of the support structure according to the invention are clear from what is described above with reference to the figures and are briefly as follows.

Con riferimento alle figure 9, 10 dei disegni, in funzione della lunghezza del mobile da realizzare (ad esempio una scrivania sospesa) una pluralità di strutture 10 (almeno due) è prima agganciata alle piastre 16 (barra 49), 35 fissate a parete, dopo di che sono eseguite tutte le regolazioni sopra descritte, vale a dire: la perpendicolarità dei bracci 12 rispetto alla parete 17, il parallelismo reciproco dei bracci 12 (mediante rotazione secondo la freccia F di figura 4), la messa in bolla degli stessi bracci 12, agendo sui grani 39 (mediante rotazione secondo la freccia F1 di figura 6), e la regolazione in verticale (secondo le frecce F2 di figura 5) agendo sui grani 18. With reference to figures 9, 10 of the drawings, depending on the length of the piece of furniture to be made (for example a suspended desk) a plurality of structures 10 (at least two) is first hooked to the plates 16 (bar 49), 35 fixed to the wall, after which all the adjustments described above are carried out, namely: the perpendicularity of the arms 12 with respect to the wall 17, the reciprocal parallelism of the arms 12 (by rotation according to the arrow F in figure 4), the leveling of the arms themselves 12, acting on the dowels 39 (by rotation according to the arrow F1 of figure 6), and the vertical adjustment (according to the arrows F2 of figure 5) by acting on the dowels 18.

I grani 39 e 18 costituiscono rispettivamente primi e secondi mezzi di regolazione della struttura 10, agenti fra le piastre 35 e 16 ed il montante 11. The grains 39 and 18 respectively constitute first and second adjustment means of the structure 10, acting between the plates 35 and 16 and the upright 11.

Infine, attraverso il serraggio del grano 24 e della vite 32 sono recuperati i giochi ed i vari componendi sono bloccati in posizione (figure 1-6). Finally, by tightening the dowel 24 and the screw 32 the clearances are recovered and the various components are locked in position (figures 1-6).

Il grano 24 e le viti 32 costituiscono invece mezzi di serraggio finale della struttura 10 per il recupero dei giochi, agenti rispettivamente fra dette piastre 16 e 35. The dowel 24 and the screws 32, on the other hand, constitute final tightening means of the structure 10 for the recovery of the play, acting respectively between said plates 16 and 35.

Le figure 7,8 illustrano un'altra possibile forma di realizzazione dell’invenzione ove i componenti uguali, o equivalenti, a quelli illustrati nelle figure 1-6 sono indicati con gli stessi numeri di riferimento aumentati di 100. Figures 7,8 illustrate another possible embodiment of the invention where the components equal, or equivalent, to those illustrated in Figures 1-6 are indicated with the same reference numbers increased by 100.

In questa forma di realizzazione dell’invenzione è previsto un braccio 112 avente sezione trasversale a “C” uguale a quella del montante 111. In this embodiment of the invention, an arm 112 is provided with a cross section of "C" equal to that of the upright 111.

Come si vede chiaramente dai disegni il braccio 112 è fissato al montante 111 mediante due squadrette laterali 50 che sono avvitate sulle ali 113, 113a rispettivamente del montate 111 e del braccio 112. As can be clearly seen from the drawings, the arm 112 is fixed to the upright 111 by means of two lateral brackets 50 which are screwed onto the wings 113, 113a of the mount 111 and of the arm 112, respectively.

Più precisamente, il fissaggio fra montante 111 e braccio 112 è realizzato mediante coppie di spine di estremità 51 e coppie di viti centrali 52. Le spine 51 passano attraverso fori 53, 54, rispettivamente della squadretta 50 e delle ali 113, 113a, mentre le viti 52 si avvitano attraverso fori filettati 55 delle ali 113, 113a, passando attraverso fori 56 della squadretta 50. Da ciascuna squadretta 50 sporgono lateralmente un dado 138, fissato ad essa, attraverso il quale dado 138 si avvita un grano 139. Dado 138 e grano 139 hanno chiaramente la medesima funzione dei componenti 38 e 39 della realizzazione delle figure 1-6. More precisely, the fixing between the upright 111 and the arm 112 is achieved by means of pairs of end pins 51 and pairs of central screws 52. The pins 51 pass through holes 53, 54, respectively of the bracket 50 and of the wings 113, 113a, while the screws 52 are screwed through threaded holes 55 of the wings 113, 113a, passing through holes 56 of the bracket 50. From each bracket 50 protrude laterally a nut 138, fixed to it, through which nut 138 is screwed a dowel 139. Nut 138 and grain 139 clearly have the same function as components 38 and 39 of the embodiment of Figures 1-6.

Le strutture di supporto a sbalzo 10, 110 secondo l’invenzione sono in grado di ricevere sui bracci 12, 112 ripiani di qualsiasi tipo che saranno fissati in posizione mediante caratteristici mezzi di montaggio a scorrimento. The cantilevered support structures 10, 110 according to the invention are able to receive on the arms 12, 112 shelves of any type that will be fixed in position by means of characteristic sliding assembly means.

Analogamente, ai montanti 11, 111 potranno essere fissati pannelli estetici. Similarly, aesthetic panels can be fixed to the uprights 11, 111.

Tra le varianti previste è possibile che le piastre 16, 35 siano raggruppate in un unico elemento di supporto (piastra unica) senza peraltro uscire dall’ambito di protezione dell’invenzione. Among the variants provided, it is possible that the plates 16, 35 are grouped into a single support element (single plate) without however going out of the scope of protection of the invention.

Un esempio di scrivania sospesa S (figure 9, 10), è realizzato fissando un ripiano orizzontale R ai bracci 12 ed un pannello verticale P ai montanti 11. An example of a suspended desk S (figures 9, 10) is made by fixing a horizontal shelf R to the arms 12 and a vertical panel P to the uprights 11.

I sistemi di montaggio a scorrimento del ripiano R ai bracci 12 possono essere i più svariati. The sliding assembly systems of the shelf R to the arms 12 can be the most varied.

Il ripiano R può ad esempio e vantaggiosamente essere provvisto (sulla superficie sottostante) di manicotti M di materia plastica che sono facilmente e rapidamente infilati e fatti scorrere sui bracci 12. The shelf R can for example and advantageously be provided (on the underlying surface) with sleeves M of plastic material which are easily and quickly inserted and made to slide on the arms 12.

Nelle figure 9, 10 le strutture di supporto 10, superiormente, sono agganciate anziché a piastre, ad una barra 49 fissata a parete. In figures 9, 10 the support structures 10, at the top, are hooked instead of plates to a bar 49 fixed to the wall.

Con C è indicata una canalina di passaggio di cavi di servizio che viene coperta dal ripiano R montato a scorrimento infilando i manicotti M sui bracci 12, come indicato dalla freccia F3. Reference C indicates a duct for passing service cables which is covered by the shelf R mounted sliding by inserting the sleeves M on the arms 12, as indicated by the arrow F3.

Sono così conseguiti gli scopi menzionati al preambolo della descrizione. The purposes mentioned in the preamble of the description are thus achieved.

L’ambito di protezione della presente invenzione è pertanto definito dalle rivendicazioni seguenti. The scope of protection of the present invention is therefore defined by the following claims.
