DESCRIZIONE DESCRIPTION

La presente invenzione si riferisce ad una scrivania con piano innalzabile tramite coppie di leve che lo mantengono sempre parallelo al suolo e mai debordante posteriormente. PiÃ¹ in particolare la presente invenzione Ã ̈ costituita da un telaio a U rovescia cui Ã ̈ solidale il piano e nei cui fianchi sono inserite e snodate le teste di due coppie di leve opportunamente sagomate che allâ€™altro capo sono inserite e snodate nella coppia di fianchi in lamiera scatolata, opportunamente sagomati e tra loro collegati da unâ€™ asta di irrigidimento e che presentano gli attacchi inferiori per una coppia di molle a gas, allâ€™altro capo snodate ad una coppia di attacchi, opportunamente sagomati, solidali alla coppia di leve inferiori cui Ã ̈ altresÃ¬ solidale la coppia di blocchetti di sicurezza che, durante la rotazione delle leve, coadiuvata dalla spinta delle molle a gas e vincolata sia dal posizionamento a parallelogramma dei punti di rotazione che dallâ€™asta di sincronia che vincola le leve superiori, interferisce con il pendolo di sicurezza, armandolo a fine corsa, corsa durante la quale il piano si innalza sempre parallelo al suolo e mai debordando posteriormente, in quanto i punti di rotazione anteriori del parallelogramma giacciono sulla stessa verticale sia con la scrivania chiusa che innalzata. Per riabbassare il piano della scrivania basterÃ spingerlo leggermente verso lâ€™alto cosÃ¬ da poter spingere indietro il pendolo di sicurezza, disarmandolo, cosicchÃ© le leve, ruotando a ritroso coadiuvate dal lavoro della coppia di molle a gas riposizionino il piano con un movimento fluido, senza alcuno sforzo ed in assoluta sicurezza. L'invenzione di cui sopra eâ€™ volta a risolvere i problemi di spazio soprattutto nel campo dellâ€™arredo e dellâ€™ufficio. Molte sono state le soluzioni proposte nel corso del tempo, ma nessuna risolve il problema nei termini in cui lo risolve il trovato. Le soluzioni fino ad oggi proposte offrono scrivanie innalzabili tramite attuatori elettrici o molle a gas che, perÃ² si innalzano solo per regolare a piacere lâ€™altezza del piano, essenzialmente per situazioni di lavoro sia da seduti che in piedi e che, comunque, per come sono realizzate, non hanno una corsa sufficiente per permettere di accedere agevolmente a quanto riposto sotto il piano scrivania Ulteriore inconveniente delle invenzioni note Ã ̈ che le scrivanie sollevabili non possono venire collocate davanti a librerie, o altri mobili, poichÃ©, cosÃ¬ facendo, risultano inaccessibili i vani dietro la scrivania. Scopo della presente invenzione e' quello di ovviare a questi e ad altri inconvenienti, realizzando una scrivania con piano innalzabile tramite coppie di leve che lo mantengono sempre parallelo al suolo e mai debordante posteriormente. PiÃ¹ in particolare, scopo della presente invenzione e' quello di realizzare una scrivania innalzabile con corsa sufficiente a permettere lâ€™agevole accesso a quanto riposto sotto il piano scrivania. Ulteriore scopo della presente invenzione eâ€™ quello di realizzare una scrivania innalzabile che puÃ² venire collocata davanti a librerie,box con installati computer o od altri mobili poichÃ© dotata di un cinematismo che permette un innalzamento tale da consentire un facile accesso a tutto ciÃ² che si trova dietro alla scrivania. Questi ed altri scopi nonchÃ© ulteriori caratteristiche della scrivania con piano innalzabile tramite coppie di leve che lo mantengono sempre parallelo al suolo e mai debordante posteriormente, oggetto della presente invenzione, verranno meglio evidenziate nel corso della descrizione che segue di una sua forma di esecuzione preferita e non limitativa, fatta con riferimento alle allegate 3 tavole di disegno in cui si rappresenta schematicamente : The present invention refers to a desk with a top that can be raised by means of pairs of levers which always keep it parallel to the ground and never protruding from the rear. More specifically, the present invention consists of an inverted U-shaped frame to which the top is integral and in whose sides the heads of two pairs of suitably shaped levers are inserted and articulated, which at the other end are inserted and articulated in the pair. of boxed sheet metal sides, suitably shaped and connected to each other by a stiffening rod and which have the lower attachments for a pair of gas springs, at the other end jointed to a pair of attachments, suitably shaped, integral with the pair of lower levers which are also integral with the pair of safety blocks which, during the rotation of the levers, assisted by the thrust of the gas springs and constrained both by the parallelogram positioning of the rotation points and by the synchronization rod which constrains the upper levers, interferes with the safety pendulum, arming it at the end of its stroke, a stroke during which the top always rises parallel to the ground and never overflows back rightly, since the front pivot points of the parallelogram lie on the same vertical both with the desk closed and raised. To lower the desk top it will be sufficient to push it slightly upwards so as to be able to push the safety pendulum back, disarming it, so that the levers, turning backwards assisted by the work of the gas springs, reposition the top with one movement fluid, without any effort and in absolute safety. The above invention is aimed at solving space problems especially in the field of furniture and the office. Many solutions have been proposed over time, but none solves the problem in the terms in which the invention solves it. The solutions proposed up to now offer desks that can be raised by means of electric actuators or gas springs which, however, only rise to adjust the height of the top as desired, essentially for work situations both seated and standing and which, in any case, for how they are made, they do not have sufficient travel to allow easy access to what is stored under the desk top Another drawback of known inventions is that the liftable desks cannot be placed in front of bookcases, or other furniture, since, in so doing , the compartments behind the desk are inaccessible. The purpose of the present invention is to obviate these and other drawbacks, by making a desk with a top that can be raised by means of pairs of levers which always keep it parallel to the ground and never protruding from the rear. More in particular, the object of the present invention is that of realizing a desk that can be raised with sufficient travel to allow easy access to what is stored under the desk top. A further purpose of the present invention is that of realizing a liftable desk that can be placed in front of bookcases, boxes with installed computers or other furniture as it is equipped with a kinematic mechanism that allows a raising such as to allow easy access to everything that it is located behind the desk. These and other purposes as well as further characteristics of the desk with top that can be raised by means of pairs of levers that keep it always parallel to the ground and never projecting backwards, object of the present invention, will be better highlighted in the course of the following description of one of its preferred embodiments. and not limitative, made with reference to the attached 3 drawing tables which schematically represent:

Si precisa che i colori dei disegni non sono vincolanti ed hanno lâ€™unico scopo di rendere maggiormente esplicativi i disegni stessi. Con riferimento alle citate figure, la scrivania con piano innalzabile tramite coppie di leve che lo mantengono sempre parallelo al suolo e mai debordante posteriormente, secondo l'invenzione, presenta basilarmente: un telaio a U rovescia (1) cui Ã ̈ solidale, tramite la coppia di staffe (2-2a) il piano (3) e nei cui fianchi sono inserite e snodate le teste (4-4a,5-5a) di due coppie di leve (6-6a,7-7a) opportunamente sagomate che, allâ€™altro capo, (8-8a,9-9a) sono inserite e snodate nella coppia di fianchi in lamiera scatolata (10-10a) opportunamente sagomati e tra loro collegati da unâ€™ asta di irrigidimento (11), e che presentano gli attacchi inferiori (12-12a) per una coppia di molle a gas (13-13a), allâ€™altro capo snodate ad una coppia di attacchi (14-14a), opportunamente sagomati, solidali alla coppia di leve inferiori (6-6a) cui Ã ̈ altresÃ¬ solidale la coppia di blocchetti di sicurezza (15-15a) che, durante la rotazione delle leve (6-6a,7-7a), coadiuvata dalla spinta delle molle a gas (13-13a) e vincolata sia dal posizionamento a parallelogramma dei punti di rotazione (4-4a,5-5a,8-8a,9-9a) che dallâ€™asta di sincronia (16) che vincola le leve superiori (7-7a), interferisce con il pendolo di sicurezza (17-17a) snodato ai fianchi (10-10a), armandolo a fine corsa, corsa durante la quale il piano (3) si innalza sempre parallelo al suolo e mai debordando posteriormente, in quanto i punti di rotazione anteriori del parallelogramma (4-4a,5-5a) giacciono sulla stessa verticale sia con il piano-scrivania (3) chiuso che innalzato. Per riabbassare il piano della scrivania (3) basterÃ spingerlo leggermente verso lâ€™alto cosÃ¬ da poter spingere indietro il pendolo di sicurezza (17-17a), disarmandolo, cosicchÃ© le leve (6-6a,7-7a), ruotando a ritroso, coadiuvate dal lavoro della coppia di molle a gas (13-13a) riposizionino il piano (3) con un movimento fluido, senza alcuno sforzo ed in assoluta sicurezza. L'invenzione, cosi' come sopra descritta, e' stata proposta a puro titolo esemplificativo, intendendosi che essa potra' essere suscettibile di numerose modifiche o varianti, tutte, peraltro, rientranti nell'ambito della presente invenzione; apportando leggere o piu' sofisticate modifiche, rettifiche ed accorgimenti, il monoblocco potra' avere applicazioni diverse, anche in altri campi, cosiâ€™ come potraâ€™, sempre nel campo dellâ€™arredamento venire utilizzato per altri scopi. It should be noted that the colors of the drawings are not binding and have the sole purpose of making the drawings themselves more explanatory. With reference to the aforementioned figures, the desk with the top that can be raised by means of pairs of levers that keep it always parallel to the ground and never protruding from the rear, according to the invention, basically has: an inverted U-shaped frame (1) to which it is integral, by means of the pair of brackets (2-2a) the surface (3) and in whose sides the heads (4-4a, 5-5a) of two pairs of levers (6-6a, 7-7a) are inserted and articulated suitably shaped which, at the other end, (8-8a, 9-9a) they are inserted and articulated in the pair of suitably shaped boxed sheet metal sides (10-10a) and connected to each other by a stiffening rod (11), and which have the lower attachments (12-12a) for a pair of gas springs (13-13a), at the other end jointed to a pair of attachments (14-14a), suitably shaped, integral with the pair of lower levers (6 -6a) which is also integral with the pair of safety blocks (15-15a) which, during the rotation of the levers (6-6a, 7-7a), assisted by the thrust of the lle gas (13-13a) and constrained both by the parallelogram positioning of the rotation points (4-4a, 5-5a, 8-8a, 9-9a) and by the synchronous rod (16) which binds the levers (7-7a), interferes with the safety pendulum (17-17a) articulated at the sides (10-10a), arming it at the end of its stroke, a stroke during which the plane (3) always rises parallel to the ground and never overflows posteriorly, since the front rotation points of the parallelogram (4-4a, 5-5a) lie on the same vertical both with the desk top (3) closed and raised. To lower the desk top (3) it will be sufficient to push it slightly upwards so as to be able to push back the safety pendulum (17-17a), disarming it, so that the levers (6-6a, 7-7a), rotating backwards, assisted by the work of the pair of gas springs (13-13a), reposition the top (3) with a fluid movement, without any effort and in absolute safety. The invention, as described above, has been proposed purely by way of example, it being understood that it may be susceptible of numerous modifications or variations, all of which, however, fall within the scope of the present invention; by making slight or more sophisticated modifications, adjustments and expedients, the monobloc can have different applications, also in other fields, as well as it can, always in the field of furniture to be used for other purposes.
