Description

  

  Chaise articulée.    La présente invention a pour objet une  chaise     transforniable    depuis une position       liaute,    équivalente<B>à</B> celle d'une chaise nor  male, jusqu'à une position inférieure  extrême permettant de s'allonger.  



  Cette chaise est caractérisée en ce     quMle     comprend deux paires de montants, articulées  l'une sur l'autre, l'une de ces paires consti  tuant le dossier et les pieds avant, taudis que       Pautre    paire forme les deux     a-Litres    pieds et  sert<B>à</B>     J'articulation    du     chûssis    du siège, les  deux paires de montants étant combinées avec  un élément (le     veiTouillage    épousant la forme  du dossier,

   et muni de crans     qui    s'engagent  sur une pièce transversale du siège et blo  quent celui-ci dans diverses positions     corres-          noifflatit        it    celles des crans, avec butée dans  la position la plus basse du siège.  



  Une forme d'exécution du siège selon     l'in-          vviition    est représentée,<B>à</B> titre d'exemple, sur  les dessins annexés:  La     fig.   <B>1</B> en est une coupe en élévation.  lia     fig.    2 montre,<B>à</B> plus grande échelle,  la ferrure servant<B>à</B> l'accrochage et au ver  rouillage du siège.  



  La fi--.<B>3</B> est une vue de détail du mode de  <B>c</B>  fixation     du    siège avec les montants du dossier.  La     fig.    4 est une vue de détail de la glis  sière fixée sur le montant principal.  



  Les fi".<B>5</B> et<B>6</B>     ,;ont    des schémas explicatifs  <B>CI</B>  du fonctionnement.  



  Dans la chaise représentée, un dossier est  formé de deux montants<B>1</B> réunis par des  barreaux la. Ces montants sont munis d'une         Ilissière    2     (fig.   <B>1</B> et 4). Les extrémités infé  rieures de ces montants forment les pieds  avant de la chaise. Les pieds arrière sont  formés<B>de</B> deux montants<B>3,</B> articulés, en     .1     avec les montants<B>1</B> et réunis entre eux par       une    traverse<B>11</B> qui est utilisée comme point  d'appui du pied pour le maniement de la  chaise.

   Un cadre sert de support au siège et       est    composé de deux barres métalliques<B>6</B>  articulées en<B>5</B> sur les montants<B>3</B> et traver  sées par Lin axe<B>7</B> dont les extrémités, for  mant ergot, s'engagent dans les glissières 2       (fig.   <B>3).</B> Deux montants<B>8</B> munis de barreaux  8a sont, destinés<B>à</B> remplir l'espace, créé en  cours du maniement, entre siège et dossier.  Ces montants<B>8</B> comportent un bras 12 et  sont articulés en<B>9</B> sur les montants<B>1;</B> ils  sont munis de deux ferrures<B>à</B> crans ou<B>élé-</B>  ments de verrouillage<B>10</B> qui immobilisent       Paxe   <B>7</B> le     lon--    des glissières 2.  



  Cet axe<B>7,</B> immobilisé en différents points  par les ferrures<B>à</B> crans<B>10,</B> occupe, suivant  le nombre d'encoches de- ces dernières, un       eertain    nombre de positions dont la plus<B>éle-</B>  vée confère<B>à</B> la chaise une hauteur normale,  et cet axe libéré de la ferrure<B>10,</B> allant bu  ter au fond de la glissière 2, confère<B>à</B> la  chaise une position allongée apte au repos.  



  La<B>f</B>     errure   <B>10</B>     (fig.    2) est munie de  crans, ceux-ci sont formés par un évidement  oblong dans le sens vertical, 20, et une partie  de ces crans présentent un évidement latéral  21 réservant un crochet de sécurité 22. Ces  crans sont réunis entre eux par une rampe      oblique 2ô qui invite     Fergot    de la ferrure<B>7 à</B>  tomber successivement dans chacun des crans.  



  Le maniement du siège est le suivant:  <B>1"</B> (La chaise étant en position haute):  Saisir la chaise par le montant<B>1 à</B> la hauteur  du point 12 en conservant la liberté du  mouvement des pouces.  



  20 Poser un pied au centre de la tra  verse,<B>11.</B>  



  <B>3"</B> Peser avec les pouces des mains droite  et gauche sur les bras 12 dans le sens de la  flèche     f.    Cette action a pour effet de libérer  l'axe<B>7</B> des crans de la<B>f</B>errure<B>10.</B> Si, pendant  la pesée, on agit sur le dossier<B>1</B> en l'abais  sant, on s'aperçoit que la chaise se baisse  librement. Dès que le siège est<B>à</B> la hauteur  désirée, il suffit de libérer les bras 12 pour  que la ferrure<B>10,</B> entraînée par le poids de  l'ensemble auquel<B>-</B> elle appartient, vienne  bloquer     Faxe   <B>7</B> le long -de la glissière 2.  



  La ferrure<B>10</B> n'ayant, pas de crochets de  sécurité 22 correspondant,     au:x    positions les       pl-Lis    basses, une pression du pied sur la tra  verse<B>11,</B> pendant. que l'on     souilève    les mon  tants<B>1,</B> permet au siège de prendre des<B>posi-</B>  tions de plus en plus élevées, sans avoir a  agir sur les bras 12. D'ailleurs, en exerçant  une pression brusque sur la traverse<B>11,</B>  l'axe<B>7</B> peut franchir les crans de sécurité  dans le sens de la montée.  



  Dans la forme de réalisation décrite     ci-          dessus,    le montant<B>8</B> pivote en<B>9</B>     sur    les mon  tants<B>1,</B> la ferrure<B>10</B> travaille<B>à</B> l'extension  et la pression libératrice sur les bras 12 doit  avoir lieu d'avant en arrière comme repré  senté par le schéma de la     fig.   <B>5.</B>  



  Selon une variante, représentée par le  schéma de la     fig.   <B>6,</B> le montant<B>8</B> pourrait,       a-Li    lieu de pivoter en<B>9,</B> au-dessus du système  d'accrochage, pivoter au-dessous de ce<I>sys-</I>  tème, par exemple en 4. Dans ce cas, la     fer-          mire   <B>10</B> travaillerait<B>à</B> la compression et la  pression libératrice devrait être exercée par       poubssée    d'arrière en avant,, dans le gens<B>(le</B>  la flèche.

  Articulated chair. The present invention relates to a chair which can be transformed from a straight position, equivalent <B> to </B> that of a normal chair, to an extreme lower position making it possible to lie down.



  This chair is characterized in that it comprises two pairs of uprights, articulated one on the other, one of these pairs constituting the backrest and the front legs, while the other pair forms the two legs and serves <B> à </B> I articulation of the frame of the seat, the two pairs of uprights being combined with an element (the veiTouillage following the shape of the backrest,

   and provided with notches which engage on a transverse part of the seat and block the latter in various positions corresponding to those of the notches, with a stop in the lowest position of the seat.



  An embodiment of the seat according to the invention is shown, <B> to </B> by way of example, in the accompanying drawings: FIG. <B> 1 </B> is a section in elevation. lia fig. 2 shows, <B> on a </B> larger scale, the fitting serving <B> for </B> the attachment and the rusting worm of the seat.



  The fi--. <B> 3 </B> is a detailed view of the <B> c </B> method of securing the seat with the back uprights. Fig. 4 is a detail view of the slide fixed to the main upright.



  The fi ". <B> 5 </B> and <B> 6 </B>,; have <B> CI </B> explanatory diagrams of the operation.



  In the chair shown, a backrest is formed by two uprights <B> 1 </B> joined by bars 1a. These uprights are fitted with an Ilissière 2 (fig. <B> 1 </B> and 4). The lower ends of these uprights form the front legs of the chair. The rear legs are formed <B> of </B> two uprights <B> 3, </B> articulated, in .1 with the uprights <B> 1 </B> and joined together by a crossbar <B> 11 </B> which is used as a fulcrum of the foot for the handling of the chair.

   A frame serves as a support for the seat and is made up of two metal bars <B> 6 </B> articulated in <B> 5 </B> on the uprights <B> 3 </B> and crossed by the axis < B> 7 </B> whose ends, forming a lug, engage in the guides 2 (fig. <B> 3). </B> Two uprights <B> 8 </B> fitted with bars 8a are , intended <B> to </B> fill the space, created during handling, between seat and backrest. These uprights <B> 8 </B> have an arm 12 and are articulated in <B> 9 </B> on the uprights <B> 1; </B> they are fitted with two fittings <B> to </ B> notches or <B> </B> locking elements <B> 10 </B> which immobilize the axle <B> 7 </B> along the runners 2.



  This axis <B> 7, </B> immobilized at various points by the fittings <B> with </B> notches <B> 10, </B> occupies, depending on the number of notches of the latter, a a certain number of positions, the higher <B> high- </B> gives <B> to </B> the chair a normal height, and this axis freed from the fitting <B> 10, </B> going bu ter at the bottom of the slide 2, gives <B> to </B> the chair a lying position suitable for rest.



  The <B> f </B> error <B> 10 </B> (fig. 2) is provided with notches, these are formed by an oblong recess in the vertical direction, 20, and part of these notches have a lateral recess 21 reserving a safety hook 22. These notches are joined together by an oblique ramp 2ô which invites Fergot of the fitting <B> 7 to </B> fall successively into each of the notches.



  The handling of the seat is as follows: <B> 1 "</B> (With the chair in the high position): Grasp the chair by the upright <B> 1 at </B> the height of point 12 while maintaining freedom movement of the thumbs.



  20 Place one foot in the center of the sleeper, <B> 11. </B>



  <B> 3 "</B> Weigh with the thumbs of the right and left hands on the arms 12 in the direction of the arrow f. This action has the effect of releasing the axis <B> 7 </B> from the notches <B> f </B> error <B> 10. </B> If, during weighing, we act on the folder <B> 1 </B> by lowering it, we notice that the chair can be lowered freely. As soon as the seat is <B> at </B> the desired height, it suffices to release the arms 12 so that the fitting <B> 10, </B> pulled by the weight of the set to which <B> - </B> it belongs, come and block Faxe <B> 7 </B> along slide 2.



  The fitting <B> 10 </B> having no corresponding safety hooks 22, at: x low positions, pressure of the foot on the rail <B> 11, </B> during . that one raises the uprights <B> 1, </B> allows the seat to take up <B> positions- </B> more and more high, without having to act on the arms 12. D ' elsewhere, by exerting sudden pressure on the crossbar <B> 11, </B> the axis <B> 7 </B> can pass through the safety notches in the upward direction.



  In the embodiment described above, the upright <B> 8 </B> pivots at <B> 9 </B> on the uprights <B> 1, </B> the fitting <B> 10 < / B> works <B> to </B> the extension and the releasing pressure on the arms 12 must take place from front to back as shown by the diagram in fig. <B> 5. </B>



  According to a variant, represented by the diagram of FIG. <B> 6, </B> the upright <B> 8 </B> could, a-Li instead of pivoting in <B> 9, </B> above the hooking system, pivot below of this <I> system </I>, for example in 4. In this case, the closure <B> 10 </B> would work <B> to </B> the compression and the releasing pressure should to be exercised by thrusting back and forth, in the gens <B> (the </B> arrow.

      normal chair, up to the third extreme lower position allowing to lie down, characterized in that <B> 1 </B> it comprises two pairs of uprights, articulated one on the other, the one of these pairs constituting the backrest and the front legs, while the other pair forms the other two legs and serves <B> for </B> the articulation of the frame of the seats, the two pairs of uprights being combined with a locking element conforming to the shape of the backrest,

    and provided with notches which engage on a transverse part of the seat and block the latter in various positions corresponding <B> to </B> those of the notches, with stop in the lowest position of the seat. SUB-REVENUE) ICATIONS: <B> 1. </B> Articulated chair, according to the claim, characterized in that the notches are formed by oblong recesses in the vertical direction.
