Description

Chaise de saue publique. La presente invention concerne une chaise de salle publique, telle que, par exemple, une salle de cinema ou de theätre, dans laquelle les chaises sont alignees en rangees disposees Tune derriere 1'autre. Public sauna chair. The present invention relates to a chair for a public hall, such as, for example, a cinema or theater hall, in which the chairs are aligned in rows arranged one behind the other.

Les chaises actuellement utilisees dans les salles publiques sont en general munies de siegen relevables, tandis que les autres Par ties de la chaise sont fixement reliees entre elles et au plancher de la salle. Plusieurs de ces chaises peuvent aussi etre reunies entre elles. The chairs currently used in public rooms are generally provided with retractable seats, while the other parts of the chair are fixedly connected to each other and to the floor of the room. Several of these chairs can also be joined together.

Ces chaises presentent 1'inconvenient qu'une personne dejä assise doit se lever pour laisser passer une autre personne devant la rangee de chaises. Ceci est d'abord tres desagreable pour la personne assise et mas- que, d'autre pari, la vue pour les personnes assises derriere, ce qui entraine de Brands inconvenients, surtout durant une represen- tation ou analogue. These chairs have the disadvantage that a person already seated must get up to let another person pass in front of the row of chairs. This is firstly very unpleasant for the person seated and, on the other hand, obscures the view for the persons seated behind, which causes considerable inconvenience, especially during a performance or the like.

Le but de 1'invention est d'eliminer cet ineonvenient et de donner en meme temps une Position assise plus agreable, ce dernier but pouvant etre obtenu par 1e fäit que 1e siege de la chaise selon 1'invention est fixe par rapport au dossier et que ces deux Par ties de la chaise peuvent recevoir n'importe quelle forme- appropriee pour 1'obtention dune Position assise confortable saus que 1'on ait besoin de prendre egard ä la necessite de rendre 1e siege mobile par rapport au dossier, cette necessite limitant toujours les possibili- tAs d'obtenir une forme confortable et appro- priee. The object of the invention is to eliminate this inconvenience and at the same time to give a more pleasant seated position, this last object being able to be obtained by the fact that the seat of the chair according to the invention is fixed with respect to the backrest and that these two parts of the chair can be given any shape suitable for obtaining a comfortable seated position, except that one needs to take into account the need to make the seat mobile with respect to the backrest, this need always limiting the possibilities of obtaining a comfortable and appropriate form.

Suivant 1'invention, cette chaise comporte un siege et un dossier formant un ensemble rigide monte de fagon ä pouvoir basculer autour dun axe horizontal transversal situe ä fleur du plancher sous 1e siege, 1e mouve- ment de basculement etant limite vers 1'ar- riere par une butee disposee ä 1'extremite superieure dune piece d'appui fixee au plancher. According to the invention, this chair comprises a seat and a backrest forming a rigid assembly mounted in such a way as to be able to tilt around a transverse horizontal axis located flush with the floor under the seat, the tilting movement being limited towards the rear. rear by a stop arranged at the upper end of a support piece fixed to the floor.

De telles chaises montees en rangees dans la salle peuvent etre disposees de fagon que Fon puisse faire basculer en avant 1e siege et 1e dossier des chaises dune rangee de ma- niere suffisante pour permettre ä une per sonne de passer devant la rangee de chaises arriere sann desagrement et saus deranger les personnes dejä assises Sur cette derniere ran- gee, et de faQon que 1e basculement du siege et du Bossier vers 1'avant puisse Atre effec- tue facilement et saus que la personne occu- pant cette Chaise ait besoin de se lever. Such chairs mounted in rows in the room may be arranged so that the seat and the backs of the chairs can be tilted forward in a row sufficiently to allow a person to pass in front of the rear row of chairs without inconvenience and without disturbing the people already seated On this last row, and in such a way that the tilting of the seat and the Bossier forwards can be carried out easily and without the person occupying this Chair needing to get up.

Le dessin ei-joint represente, ä titre d'exemple, une forme d'execution de la Chaise selon 1'invention. Sur ce dessin, la fig. 1 montre une rangee de trois de Ces chaises vues de derriere, tandis que la fig. 2 repre- sente deux de Ces chaises placees Tune der- riere 1'autre et constituant chacune une Chaise de l'une de deux rangees consecutives. The attached drawing represents, by way of example, one embodiment of the Chair according to the invention. In this drawing, fig. 1 shows a row of three of these chairs seen from behind, while fig. 2 represents two of these chairs placed one behind the other and each constituting a chair of one of two consecutive rows.

Le siege 1, qui constitue avec 1e Bossier 2 et avec les bras s'il y en a, un ensemble ri gide, est monte sur un Support comprenant une Partie arriere transversale 3 legerement inflechie vers 1e bas, et solidaire ä chaque extremite dune Partie laterale 4, Ces Parties 4 etant dirigees vers 1'avant et disposees sous les deux cötes du siege (fig. 2). Ces Parties 4 sont inclinees vers 1'arriere dans la Position normale et sont solidaires chacune ä. son ex trAmite anterieure dune jambe 5 dirigee vers 1e plancher et artieulee ä son extremite infe- rieure avee une ferrure 6 fixee au planeher. De cette faeon, 1'ensemble du siege et du dos- Bier peut basculer autour d'un axe horizontal transversal situe ä fleur du plancher sous 1e siege. The seat 1, which constitutes with the Bossier 2 and with the arms if there are any, a rigid assembly, is mounted on a Support comprising a transverse rear Part 3 slightly bent downwards, and integral at each end of a Part side 4, these parts 4 being directed forwards and arranged under both sides of the seat (fig. 2). These Parts 4 are inclined towards the rear in the normal position and are each integral with. its front extremity of a leg 5 directed towards the floor and hinged at its lower extremity with a fitting 6 fixed to the floor. In this way, the assembly of the seat and the backrest can tilt around a transverse horizontal axis located flush with the floor under the seat.

Daus la Position normale du siege et du Bossier, la Partie arriere transversale 3 du Support repose Sur une butee 8 portee par l'extremite superieure dune piece d'appui ri gide 7 fixee au plancher par son extremith inferieure. La butee 8 est assez large pour assurer quelle rencontre la Partie arriere 3 du Support lorsque 1e siege et 1e Bossier sont ramenes en Position normale, meme si 1e sup- Port etait soumis ä des deformations elasti- ques en raison du poids de la personne assise ou pour tonte autre raison. In the normal position of the seat and the Bossier, the transverse rear part 3 of the support rests on a stop 8 carried by the upper end of a rigid support piece 7 fixed to the floor by its lower end. The stopper 8 is large enough to ensure that the Rear Part 3 of the Support meets when the seat and the Bossier are returned to the normal Position, even if the support were subjected to elastic deformations due to the weight of the person seated. or for any other reason.

La butee 8 doit presenter un appui com- pletement rigide et comme la piece d'appui 7 ne saurait peut-etre ä elle seine assurer la rigidit6 neeessaire, elle est eta 6e vers 1'avant par des tringles obliques 9; qui relient 1'ex- tremite superieure de nette piece d'appui avee les ferrures d'articulation 6: La butee 8 a dann 1'essentiel la forme d'un erochet ouvert en haut pröt ä recevoir la Partie arriere 3 du Support. The stopper 8 must present a completely rigid support and since the support piece 7 may not be able to provide the necessary rigidity on its own, it is pushed forwards by oblique rods 9; which connect the upper extremity of the net support piece with the articulation fittings 6: The abutment 8 has essentially the shape of a hook open at the top ready to receive the rear Part 3 of the Support.

La maniere de basculer 1e siege et 1e Bos- sier en avant est saus autre comprehensible de ce qui precede. Si cela se trouve n6ces- > saire, an pourra naturellement prevoir des moyens queleonques appropries pour limiter 1'angle de baseulement en avant. Daus la , Chaise d$crite, an se sert dune chaine 10 reliant la Partie arriere 3 du Support avec la piece d'appui 7. 0n pourrait aussi employer des butees fixees dann le plancher qui limi- tent 1e mouvement des jambes 5 du Support en cooperant avee des but6es dispWes Sur lesdites jambes. The manner of tilting the seat and the Bossier forward is otherwise understandable from what precedes. If necessary, some appropriate means may of course be provided to limit the forward angle only. In the Chair described, an uses a chain 10 connecting the rear part 3 of the Support with the support piece 7. One could also use stops fixed in the floor which limit the movement of the legs 5 of the Support. by cooperating with abutments available on said legs.

Le Support de 1'ensemble du siege et du Bossier est fait de preference en tube d'acier et si 1'on veut, chacune des chaises peut natu- rellement etre retenue en Position par plus dune buttre 8: Ces butaes pourront etre dis- posees soit Sur des pieces d'appui indepen- dantes, soit Sur un Support commun. Un seul Support fixe au plancher pourrait ainsi Atre uruni ä son sommet dune baue transversale munie de butees ä ses extremites. Les butees pourmient aussi etre dispos6es Sur des pieces individuelles; qui pourront ä volonte etre reunies ou non par des tringles de renfor- eage. Daus tous Ces cas; 1es Organes de Sup port des butees pourront Atre soutenus par des tringles assurant une Position fixe des buthes. The Support of the entire seat and Bossier is preferably made of steel tubing and if desired, each of the chairs can of course be held in position by more than one buttre 8: These buttres can be provided. laid either on independent bearing parts or on a common support. A single Support fixed to the floor could thus be fitted at its top to a transverse beam provided with stops at its ends. The stops can also be arranged on individual parts; which may or may not be joined together by reinforcing rods. In all these cases; The stops Support Organs may be supported by rods ensuring a fixed position of the stops.

Laxe de rotation du Support du siege et du Bossier pourra ä volonte eire deplace plus en avant ou plus en arriere. 0n rearquera cependant que si cet axe est deplaoe trog en avant; an aura besoin dune plus Brande force pour operer 1e basculement du siege et du Bossier, tandis que si faxe, est deplace trog loin en arriere, an risquera que 1'ensemble du siege et du Bossier perde trop facilement 1'equilibre et tombe en.avant sous 1'effet d'un leger choc Sur 1'arriere du Bossier, lorsque la chaise est vide.Il sera, pour ces raisons, con venable de disposer l'axe essentiellement dans la position représentée dans le dessin. C'est naturellement en fonction de l'emplacement du centre de gravité que l'on choisira la posi- tion de l'axe de basculement. The axis of rotation of the Seat Support and the Bossier can be moved further forward or further back as desired. 0n will rearque, however, only if this axis is moved tog forward; an will need a greater force to operate the tilting of u the seat and the Bossier, while if faxed, is moved too far back, an will risk that the assembly of the seat and the Bossier loses too much balance easily and falls forward under the effect of a slight impact On the back of the Bossier, when the chair is empty.It will therefore be convenient to place the axis essentially in the position shown in the drawing. It is naturally according to the location of the center of gravity that the position of the tilting axis will be chosen.
