Descrizione della domanda di brevetto per invenzione industriale avente per titolo “Meccanismo di sollevamento per letto articolato” a Description of the patent application for industrial invention entitled "Lifting mechanism for articulated bed" a
L’invenzione di riferisce ad un meccanismo di sollevamento per letto articolato. The invention refers to a lifting mechanism for an articulated bed.
Sono noti letti articolati con meccanismi di sollevamento che permettono di sollevare e mantenere la rete (o doghe) del letto (ossia il cosiddetto piano-letto) ad una certa altezza da terra, permettendo ad una massaia di rifare il letto comodamente senza piegarsi e di avere accesso allo spazio sottostante alla rete. Articulated beds with lifting mechanisms are known that allow the bed base (or slats) to be raised and maintained (i.e. the so-called bed-base) at a certain height from the ground, allowing a housewife to make the bed comfortably without bending and have access to the space below the network.
La richiedente nel passato ha brevettato un meccanismo, posto in due esemplari uguali sui due lati opposti del telaio fisso a terra del letto, costituito da un primo e un secondo braccio di sollevamento montati tra loro sostanzialmente paralleli e incernierati al telaio e al piano-letto per formare un parallelogramma articolato. Uno dei due bracci è costruito allungabile, ossia tramite due segmenti montati telescopicamente uno nell’altro. Questo permette, una volta che il piano-letto sia stato sollevato, di inclinare il piano-letto rispetto ad un piano orizzontale, sicché il riordino del letto ne risulta facilitato. Per contrastare il peso del piano-letto e asservirne il sollevamento, si dispongono dei mezzi elastici in spinta (solitamente molle) sui due segmenti. Una molla a gas è disposta tra l’altro braccio, quello non allungabile, e il telaio, con la funzione ancora di asservire il sollevamento del pianoletto. Generalmente il braccio allungabile è costituito da manicotti a sezione rettangolare, e i mezzi elastici sono posti al loro fianco, aH’estemo. La spinta dei mezzi elastici tende a storcere il braccio allungabile, aumentando l’attrito dei suoi segmenti telescopici e richiedendo maggior forza per il sollevamento del piano-letto. Inoltre si deve impiegare una barra di torsione posta sotto il piano-letto per compensare la spinta dai mezzi elastici, con un aumento del peso e dei costi. In the past, the applicant has patented a mechanism, placed in two identical examples on the two opposite sides of the fixed frame on the ground of the bed, consisting of a first and a second lifting arm mounted substantially parallel to each other and hinged to the frame and to the bed base. to form an articulated parallelogram. One of the two arms is built extendable, that is, by means of two segments telescopically mounted one into the other. This allows, once the bed surface has been raised, to tilt the bed surface with respect to a horizontal plane, so that the rearrangement of the bed is facilitated. In order to counteract the weight of the bed base and to assist its lifting, elastic means are placed in thrust (usually springs) on the two segments. A gas spring is arranged between the other arm, the non-extendable one, and the frame, still with the function of enslaving the lifting of the platform. Generally, the extendable arm consists of sleeves with a rectangular section, and the elastic means are placed next to them, on the outside. The thrust of the elastic means tends to distort the extendable arm, increasing the friction of its telescopic segments and requiring greater force to lift the bed. Furthermore, a torsion bar placed under the bed base must be used to compensate for the thrust from the elastic means, with an increase in weight and costs.
L’invenzione risolve quindi il problema di semplificare la struttura del meccanismo, nel contempo migliorandolo ed eliminando alcuni svantaggi. The invention therefore solves the problem of simplifying the structure of the mechanism, at the same time improving it and eliminating some disadvantages.
Tali problemi sono risolti da un meccanismo di sollevamento per la rete o il piano-letto di un letto articolato, la rete o il piano-letto essendo collegato ad un telaio posato a terra, comprendente These problems are solved by a lifting mechanism for the base or the bed base of an articulated bed, the base or the bed base being connected to a frame placed on the ground, comprising
- un primo e un secondo braccio di sollevamento montati tra loro sostanzialmente paralleli e incernierati al telaio e al piano-letto per fonnare un parallelogramma articolato, uno dei due bracci essendo allungabile tramite due segmenti montati telescopicamente uno nell’altro, - a first and a second lifting arm mounted substantially parallel to each other and hinged to the frame and to the bed surface to form an articulated parallelogram, one of the two arms being extendable by means of two segments mounted telescopically one in the other,
- mezzi elastici in spinta tra i due segmenti atti a contrastare il peso del piano-letto e asservirne il sollevamento, - elastic means in thrust between the two segments designed to counteract the weight of the bed base and enslave its lifting,
caratterizzato dal fatto che detti mezzi elastici sono disposti dentro uno o entrambi detti segmenti. characterized in that said elastic means are arranged inside one or both of said segments.
In questo modo la spinta dei mezzi elastici è diretta e si scarica lungo la direzione di spostamento dei segmenti telescopici, e non induce alcuno sforzo laterale che tenderebbe a farli piegare uno sull’altro. Ne consegue un migliorato scorrimento reciproco dei segmenti telescopici perché rattrito è minore, e la possibilità di eliminare la barra di torsione. Una costruzione preferita prevede che detti segmenti abbiano sezione circolare, cosa che consente di migliorarne lo scorrimento c ne evita oscillazioni dato che si riducono i giochi meccanici. Molto semplicemente si possono usare per detti segmenti dei manicotti metallici. Preferibilmente detti mezzi elastici comprendono una molla a gas, oggetto di facile reperibilità ma molto affidabile. Preferibilmente la molla a gas ha il corpo montato dentro un segmento e lo stelo connesso in spinta sull’altro segmento, ossia lo stelo è montato in spinta internamente ad uno dei due seg Lenti. Ulteriori vantaggi si hanno qualora si adotti un elemento montato tra i due segmenti atto a diminuire il mutuo coefficiente di attrito, ad es. un anello o una guarnizione o un collarino, preferibilmente in materiale a basso coefficiente di attrito come il Teflon®, applicato coassialmente sopra e/o dentro il bordo del segmento che contiene l’altro. I vantaggi dell'invenzione saranno meglio chiariti dalla seguente descrizione di una preferita forma di realizzazione, illustrata nel disegno allegato che mostra un piano-letto sollevabile con un meccanismo secondo Finvenzione, nel quale In this way, the thrust of the elastic means is directed and discharged along the direction of movement of the telescopic segments, and does not induce any lateral effort that would tend to make them bend over each other. The result is an improved reciprocal sliding of the telescopic segments because there is less friction, and the possibility of eliminating the torsion bar. A preferred construction provides that said segments have a circular cross-section, which makes it possible to improve their sliding and avoid oscillations since mechanical play is reduced. Very simply, metal sleeves can be used for said segments. Preferably, said elastic means comprise a gas spring, an object that is easy to find but very reliable. Preferably, the gas spring has the body mounted inside a segment and the stem connected in thrust on the other segment, ie the stem is mounted in thrust internally to one of the two segments. Further advantages are obtained if an element mounted between the two segments is adopted which is suitable for decreasing the mutual coefficient of friction, for example. a ring or a gasket or a collar, preferably in low friction coefficient material such as Teflon®, applied coaxially above and / or inside the edge of the segment that contains the other. The advantages of the invention will be better clarified by the following description of a preferred embodiment, illustrated in the attached drawing which shows a liftable bed surface with a mechanism according to the invention, in which

Fig. 4 mostra una vista assonometrica in esploso del meccanismo di fig. 1. Fig. 4 shows an exploded axonometric view of the mechanism of fig. 1.
II meccanismo (o articolazione) dell’invenzione è montato su un telaio 10 fisso a terra, che in condizioni di riposo (piano-letto non sollevato) serve come appoggio ad un piano letto o supporto per la rete 20. Il telaio 10 fa da basamento al letto (fig. 1). Con una nota manovra, il piano letto 20 si può sollevare rispetto al telaio 10 (fig. 2) e, da sollevato, si può inclinare rispetto ad un piano orizzontale (fig. 3). I movimenti consentiti al piano-letto 20 sono sostanzialmente noti (v. anche frecce nelle figg. 1-3). The mechanism (or articulation) of the invention is mounted on a frame 10 fixed to the ground, which in rest conditions (bed surface not raised) serves as a support for a bed surface or support for the bed base 20. The frame 10 acts as a bed base (fig. 1). With a known maneuver, the bed surface 20 can be raised with respect to the frame 10 (fig. 2) and, when raised, it can be tilted with respect to a horizontal plane (fig. 3). The movements allowed to the bed surface 20 are substantially known (see also arrows in Figs. 1-3).
Il meccanismo che permette i movimenti del piano letto-letto 20 è montato in due esemplari uguali su due lati del letto, e comprende due bracci rigidi 30, 40, ciascuno imperniato girevolmente sia al telaio 10 che al piano-letto 10 con perni, indicati genericamente con 12. Il braccio 30 è un pezzo unico, mentre il braccio 40 ha struttura telescopica allungabile ed è formato da due segmenti tubolari cilindrici o manicotti cavi 42, 44. Il segmento 44 può scorrere quindi alPintemo del segment 4M I bràcci 30, 40 sono montati tra loro sostanzialmente paralleli, per formare un parallelogramma articolato col quale alzare e sostenere il piano-letto 10. The mechanism that allows the movements of the bed-bed surface 20 is mounted in two identical examples on two sides of the bed, and comprises two rigid arms 30, 40, each pivotally pivoted both to the frame 10 and to the bed-surface 10 with pins, indicated Generally with 12. The arm 30 is a single piece, while the arm 40 has an extendable telescopic structure and is formed by two cylindrical tubular segments or hollow sleeves 42, 44. The segment 44 can therefore slide inside the segment 4M The arms 30, 40 they are mounted substantially parallel to each other, to form an articulated parallelogram with which to raise and support the bed surface 10.
Come si vede dalle figure, per ammortizzare i due segmenti 42, 44 si dispone una molla a gas 50 (v. fig. 4 dove è mostrata schematizzata a tratteggio) alloggiata alPintemo del segmento 44, con lo stelo 46 (v. fig. 3) internamente collegato con, e in spinta sul, segmento 42. Poiché quindi la spinta della molla 50 avviene assialmente rispetto ai segmenti 42, 44 e non lateralmente, essi non subiscono alcuna deformazione o piegamento laterale (è stato eliminato il momento torcente), e la stabilità e la facilità di scorrimento relativo ne risulta migliorata. La molla a gas 50, o ogni mezzo equivalente, può essere posta dentro uno solo dei segmenti 42, 44 e/o in entrambi, a seconda delle sue dimensioni e/o delle caratteristiche desiderate per il meccanismo. As can be seen from the figures, to dampen the two segments 42, 44 a gas spring 50 is arranged (see fig. 4 where it is shown schematically in hatched form) housed inside the segment 44, with the stem 46 (see fig. 3). ) internally connected with, and thrust on, segment 42. Since therefore the thrust of the spring 50 occurs axially with respect to the segments 42, 44 and not laterally, they do not undergo any lateral deformation or bending (the torque has been eliminated), and the stability and ease of relative sliding is improved. The gas spring 50, or any equivalent means, can be placed inside only one of the segments 42, 44 and / or both, depending on its dimensions and / or on the characteristics desired for the mechanism.
Anche se nelle figure è mostrata una nota barra di torsione 60, atta a collegare e stabilizzare i due meccanismi del letto, in pratica essa si è dimostrata non necessaria. Grazie alla sezione circolare dei segmenti 42, 44, il loro scorrimento relativo risulta migliorato poiché non vi sono spigoli striscianti su cui si possono concentrare gli sforzi meccanici. Per migliorare ancora tale scorrimento, si preferisce montare all’imboccatura del segmento 42 un collarino 62 (v. fig. 4), ad es. in Teflon®, con lo scopo di mantenere coassiali e con un certo gioco reciproco (dentro il segmento 42) - nonché per meglio guidare - i due segmenti 42, 44, evitando sfregamenti indesiderati. Although in the figures a known torsion bar 60 is shown, adapted to connect and stabilize the two mechanisms of the bed, in practice it has proved unnecessary. Thanks to the circular section of the segments 42, 44, their relative sliding is improved since there are no sliding edges on which mechanical stresses can be concentrated. To further improve this sliding, it is preferred to mount a collar 62 at the mouth of segment 42 (see fig. 4), eg. in Teflon®, with the aim of maintaining coaxial and with a certain reciprocal play (within segment 42) - as well as to better guide - the two segments 42, 44, avoiding unwanted rubbing.
Una molla a gas 70, imperniata tramite perni 12 al telaio 10 e al braccio 30, completa il meccanismo. La sua funzione è asservire il sollevamento del piano-letto 10 e bilanciarne il peso. A gas spring 70, pivoted by pins 12 to the frame 10 and to the arm 30, completes the mechanism. Its function is to enslave the lifting of the bed surface 10 and balance its weight.
