Description

       

  Dispositif tournant, réglable en hauteur  et basculant pour relier un siège<B>à</B> un socle    La présente invention a pour objet un dispositif  tournant, réglable en hauteur et basculant pour relier  un siège<B>à</B> un socle.  



  Le dispositif selon l'invention est caractérisé en  ce qu'il est constitué par un fût fixé<B>à</B> l'extrémité  d'une vis pouvant se visser dans un cylindre se fixant  au socle, ce fût contenant intérieurement un ressort  reposant sur une articulation hémisphérique solidaire  d'une tige portant,<B>à</B> sa partie supérieure, une  deuxième articulation hémisphérique permettant le  pivotement d'un plateau articulé sur un axe perpen  diculaire<B>à</B> l'axe vertical du fût et tourillonnant dans  des paliers solidaires de ce dernier.  



  Le dessin annexé représente,<B>à</B> titre d'exemple,  une forme d'exécution particulière du dispositif, ob  jet de l'invention.  



  La     fig.   <B>1</B> est une vue de face du dispositif pivo  tant réglable en hauteur pour sièges.  



  La     fig.    2 est une coupe suivant la ligne     II-11    de  la     fig.   <B>1.</B>  



  La     fig.   <B>3</B> est une coupe montrant le dispositif  incliné.  



  La     fig.    4 est un plan de la partie supérieure du  dispositif.  



  Le dispositif représenté comprend un fût<B>1</B> com  portant,<B>à</B> sa partie supérieure, un bossage 2 venu  de fonderie, percé d'un trou<B>3.</B>  



  L'extrémité inférieure 4 du fût<B>1</B> est fermée par  une pièce<B>5</B> maintenue par quatre vis<B>6, 7</B> disposées  <B>à</B>     901,    les unes des autres et logées dans des trous  percés dans la base du fût<B>1.</B>  



  Une tige filetée<B>8</B> est fixée rigidement dans la  pièce<B>5</B> et se visse dans un chapeau 8a percé d'un  trou taraudé<B>8b.</B> Le socle<B>9</B> constitué par une pièce  de fonderie, en alliage léger par exemple, contient  intérieurement un fourreau 9a dans lequel peut tour-         ner    librement la tige<B>8.</B> Le fourreau 9a comporte,  <B>à</B> sa partie supérieure, un collet<B>9b</B> formant butée  pour des vis<B>10</B> solidaire du chapeau 8a. Un roule  ment<B>à</B> billes<B>11</B> est interposé entre le dessus du  fourreau 9a et le fond du chapeau 8a. Lorsqu'on  désire élever le fût<B>1,</B> on visse le chapeau 8a ou on  fait tourner le siège en maintenant le chapeau.

   Dans  <B>le</B> cas contraire, où l'on désire abaisser le fût<B>1,</B> on  dévisse le chapeau 8a ou on fait tourner le siège en  sens inverse, en maintenant toujours le chapeau.  



  Le roulement<B>à</B> billes<B>11</B> permet la rotation du  siège par rapport au socle sans modifier la hauteur  du siège.  



  Une fenêtre 12 est percée<B>à</B> la partie supérieure  <B>du</B> fût<B>1.</B>    Un ressort<B>13</B> est placé<B>à</B> l'intérieur du fût<B>1</B> et  est maintenu,<B>à</B> sa partie inférieure, par une cou  ronne 14 comportant un évidement hémisphérique  <B>15</B> coopérant avec une pièce de forme correspon  dante<B>16</B> solidaire de la base d'une tige<B>17.</B> Cette  dernière, qui traverse une couronne<B>18</B> vissée<B>à</B> l'ex  trémité supérieure du fût formant butée pour le res  sort<B>13,</B> maintient,<B>à</B> son extrémité supérieure,

   une       demi-sphère   <B>19</B> venant en butée contre un écrou 20  se vissant sur la partie filetée supérieure     l7a    de la  tige<B>17.</B> La couronne<B>18</B> est percée dans sa partie  inférieure de trous équidistants     l8a.     



  Une plaque 21 est percée, en son milieu, d'un  trou tronconique 22 destiné<B>à</B> recevoir,<B>à</B> sa partie  supérieure, la pièce     demi-sphérique   <B>19.</B> Le trou 22  est prolongé par deux petites ouvertures 22a,<B>22b</B>  diamétralement opposées. La plaque 21 présente  deux bossages 24,<B>25</B> et est articulée par l'intermé  diaire d'un     axe26sur    un     bossage2    solidaire du fût<B>1.</B>  L'assise<B>27</B> du siège est fixée sur la plaque 21.  



  <B>CI</B>      Lorsque     rutilisateur    désire incliner son siège vers       rarriùre,    il s'appuie sur la partie arrière de l'assise et,  de ce fait, la tige<B>17</B> est tirée vers le haut, comme  représenté<B>à</B> la     fig.   <B>3.</B> Cette action a pour effet de  comprimer le ressort<B>13</B>     jusqu7au    moment où les  spires du ressort<B>11</B> sont presque jointives, la com  pression du ressort étant presque maximum.  



  Le retour<B>à</B> la position horizontale est automa  tique puisque, dès que l'utilisateur cesse d'exercer  une pression sur     rarriùre    de rassise, le ressort<B>11</B>  rappelle les différents organes dans la position repré  sentée aux fi-.<B>1</B> et 2.  



  La couronne<B>18,</B> percée des trous     l8a    et accessi  ble par la lumière 12, a pour but de comprimer<B>à</B>  -volonté le ressort<B>13</B> et, de ce fait, d'opposer une  résistance plus ou     moint    forte<B>à</B> la traction de la tige       17.        Ce        dispositif        permet        de        rég        ,ler        le        basculement        du     siège en fonction du poids<B>de</B> son occupant.  



  Dans certains cas, le dispositif décrit peut être  monté pour     que    l'assise du siège pivote vers l'avant,  l'articulation constituée par les bossages 2, 24,<B>25</B>  et l'axe<B>26</B> étant placée sous l'avant de     lassise    du  siège.  



  Le dispositif décrit ci-dessus est d'une fabrication  simple, d'une grande robustesse du fait de sa sirapli-    cité et suffisamment esthétique pour un siège de  bureau.



  Rotating, height-adjustable and tilting device for connecting a seat <B> to </B> a base The present invention relates to a rotating device, adjustable in height and tilting for connecting a seat <B> to </B> a basement.



  The device according to the invention is characterized in that it consists of a barrel fixed <B> to </B> the end of a screw which can be screwed into a cylinder fixed to the base, this barrel internally containing a spring resting on a hemispherical articulation integral with a rod carrying, <B> to </B> its upper part, a second hemispherical articulation allowing the pivoting of a plate articulated on a perpendicular axis <B> to </B> the vertical axis of the barrel and journaling in bearings integral with the latter.



  The appended drawing represents, <B> by </B> by way of example, a particular embodiment of the device, object of the invention.



  Fig. <B> 1 </B> is a front view of the height-adjustable pivot device for seats.



  Fig. 2 is a section taken along line II-11 of FIG. <B> 1. </B>



  Fig. <B> 3 </B> is a section showing the tilted device.



  Fig. 4 is a plan of the upper part of the device.



  The device shown comprises a shaft <B> 1 </B> comprising, <B> at </B> its upper part, a boss 2 from the foundry, pierced with a hole <B> 3. </B>



  The lower end 4 of the barrel <B> 1 </B> is closed by a part <B> 5 </B> held by four screws <B> 6, 7 </B> arranged <B> to </ B > 901, from each other and housed in holes drilled in the base of the <B> 1. </B>



  A threaded rod <B> 8 </B> is rigidly fixed in part <B> 5 </B> and is screwed into a cap 8a pierced with a threaded hole <B> 8b. </B> The base < B> 9 </B> consisting of a casting, in light alloy for example, internally contains a sleeve 9a in which the rod can freely rotate <B> 8. </B> The sleeve 9a comprises, <B > at </B> its upper part, a collar <B> 9b </B> forming a stop for screws <B> 10 </B> secured to the cap 8a. A bearing <B> with </B> balls <B> 11 </B> is interposed between the top of the sleeve 9a and the bottom of the cap 8a. When you want to raise the barrel <B> 1, </B> the cap 8a is screwed on or the seat is rotated while holding the cap.

   In <B> the </B> contrary case, where you want to lower the barrel <B> 1, </B> the cap 8a is unscrewed or the seat is rotated in the opposite direction, always holding the cap.



  The <B> </B> ball bearing <B> 11 </B> allows the seat to rotate relative to the plinth without changing the seat height.



  A window 12 is drilled <B> at </B> the upper part <B> of the </B> shaft <B> 1. </B> A spring <B> 13 </B> is placed <B> at </B> the inside of the barrel <B> 1 </B> and is maintained, <B> at </B> its lower part, by a crown 14 comprising a hemispherical recess <B> 15 </B> cooperating with a piece of corresponding shape <B> 16 </B> integral with the base of a rod <B> 17. </B> The latter, which passes through a screwed crown <B> 18 </B> < B> at </B> the upper end of the shaft forming a stop for the res sort <B> 13, </B> maintains, <B> at </B> its upper end,

   a half-sphere <B> 19 </B> coming into abutment against a nut 20 screwing on the upper threaded part 17a of the rod <B> 17. </B> The crown <B> 18 </B> is pierced in its lower part with equidistant holes l8a.



  A plate 21 is pierced, in its middle, with a frustoconical hole 22 intended <B> to </B> receive, <B> to </B> its upper part, the half-spherical part <B> 19. < / B> The hole 22 is extended by two small openings 22a, <B> 22b </B> diametrically opposed. The plate 21 has two bosses 24, <B> 25 </B> and is articulated by the intermediary of an axis26 on a boss2 integral with the barrel <B> 1. </B> The seat <B> 27 < / B> of the seat is fixed on the plate 21.



  <B> CI </B> When the user wishes to tilt his seat towards the rear, he leans on the rear part of the seat and, therefore, the rod <B> 17 </B> is pulled upwards , as shown <B> to </B> in fig. <B> 3. </B> This action has the effect of compressing the spring <B> 13 </B> until the coils of the spring <B> 11 </B> are almost contiguous, the compression of the spring being almost maximum.



  The return to <B> to </B> the horizontal position is automatic since, as soon as the user stops exerting pressure on the stale, the spring <B> 11 </B> recalls the different components in the position shown in figures <B> 1 </B> and 2.



  The crown <B> 18, </B> pierced with holes l8a and accessible by the light 12, aims to compress <B> à </B> -will the spring <B> 13 </B> and, therefore, to oppose a more or less strong resistance <B> to </B> the traction of the rod 17. This device makes it possible to regulate the tilting of the seat according to the weight <B> of </ B > its occupant.



  In some cases, the device described can be mounted so that the seat base pivots forward, the articulation constituted by the bosses 2, 24, <B> 25 </B> and the axis <B> 26 </B> being placed under the front of the seat cushion.



  The device described above is simple to manufacture, very robust because of its simplicity and sufficiently aesthetic for an office chair.
