Abstract

The seal (5) for the bottom of a door leaf is mounted on a support (6). A rail (7) is fixed to the leaf and there are two rods (8,8a) each articulated at one end on an upper spindle (9,9a) fixed to the rail and at the other end on a lower spindle (10,10a) fixed to the support. A movable part (11) is connected at one end to a return spring (17), supported on the rail, and at the other end to a strap (18) fixed to the door frame. Thus following displacement of the movable part the strap and the return spring control respectively the raising and lowering of the seal.

Description

La présente invention a pour objet un nouveau joint automatique relevable installé au bas des portes pour en améliorer l'étanchéité.The present invention relates to a new automatic seal liftable installed at the bottom of the doors to improve watertightness.

Art antérieurPrior art

On connaít déjà des joints automatiques qui ont pour fonction d'améliorer l'étanchéité de la partie basse des portes : de tels joints doivent être en contact avec le sol lorsque la porte est fermée, puis se relever au moment où la porte s'ouvre afin de ne pas rester en contact avec le sol et gêner la rotation ou le glissement de la porte.We already know automatic seals that have the function improve the tightness of the lower part of the doors: such seals must be in contact with the floor when the door is closed, then get up when the door opens so as not to remain in contact with the ground and interfere the rotation or sliding of the door.

Pour assurer ce changement de position du joint, diverses solutions techniques ont été proposées ; on connaít, par exemple, des joints montés sur une charnière et qui pivotent vers le bas sous l'effet d'un levier qui bascule en butant sur le dormant de l'huisserie. La description d'un tel dispositif est donnée notamment dans FR 1 338 522 avec une commande par levier ou dans US 3.118 193 selon lequel la rotation autour de la charnière est commandée par un poussoir et une lumière hélicoïdale.To ensure this change in position of the seal, various solutions techniques have been proposed; we know, for example, seals mounted on a hinge and which pivot downwards under the effect of a lever which swings in abutting on the frame of the frame. The description of such a device is given in particular in FR 1 338 522 with a lever control or in US 3,118,193 according to which the rotation around the hinge is controlled by a pusher and a helical light.

On connaít également des joints automatiques dont le dispositif commande une translation verticale du joint pour l'abaisser jusqu'au sol à la fermeture de la porte. Parmi les nombreux dispositifs de ce type, on peut citer US 3.703.788 ou EP 509 961 dans lesquels un poussoir agit sur une lame cintrée supportant le joint ; FR 1586 449 et FR 2.388.978 qui fonctionnent pratiquement suivant un même principe ; US 3 030 674 dans lequel le joint est supporté par plusieurs biellettes articulées et EP 209 678 selon lequel un jeu de curseurs actionnés par un poussoir vient abaisser le joint maintenu par des ressorts obliques.We also know automatic seals whose device commands a vertical translation of the joint to lower it to the ground at the door closing. Among the many devices of this type, we can cite US 3,703,788 or EP 509,961 in which a pusher acts on a blade arched supporting the joint; FR 1586 449 and FR 2 388 978 which work practically on the same principle; US 3,030,674 in which the seal is supported by several articulated links and EP 209 678 according to which a clearance sliders actuated by a pusher lowers the seal maintained by oblique springs.

Ces différents dispositifs présentent cependant des inconvénients, soit en raison de difficultés de réglage des butées poussoirs, soit en raison de leur encombrement, notamment dans le cas des mécanismes articulés par une charnière qui sont assez encombrants à l'état relevé et peuvent se détériorer assez facilement. Dans tous ces dispositifs connus, la position relevée est contrôlée par un ressort et la position abaissée est contrôlée par l'effort exercé sur les poussoirs ou les leviers venant en butée sur le dormant de la porte ; il s'ensuit que la contrainte exercée sur le joint, lorsque celui-ci est en position basse, est directement dépendante du réglage de la course du poussoir : si la course du poussoir est trop importante, le joint est écrasé sur le sol et les efforts exercés sur le mécanisme pénalisent sa fiabilité et sa longévité ; si la course du poussoir est trop faible, le joint est insuffisamment appliqué contre le sol et n'assure pas une bonne étanchéité. On s'aperçoit ainsi qu'avec ce type de dispositif, les réglages doivent être faits avec précision pour que le joint travaille dans de bonnes conditions.However, these various devices have drawbacks, either due to difficulties in adjusting the push stops, or due to their size, especially in the case of mechanisms articulated by a hinge which are quite bulky in the raised state and can deteriorate quite easily. In all these known devices, the raised position is controlled by a spring and the lowered position is controlled by the force exerted on the pushers or the levers abutting on the door frame; he it follows that the stress exerted on the joint, when the latter is in position low, is directly dependent on the adjustment of the stroke of the pusher: if the stroke of the plunger is too great, the seal is crushed on the ground and the efforts exerted on the mechanism penalize its reliability and longevity; if the stroke of the pusher is too short, the seal is insufficiently applied against the floor and does not provide a good seal. We can see that with this guy device, adjustments must be made with precision so that the joint works in good conditions.

On connaít également selon US 1 974 151 ou BE 349 584 des dispositifs articulés et commandés par une cordelette ou une chaínette solidaire par l'une de ses extrémités du dormant porteur des paumelles de la porte. Toutefois, de façon analogue aux dispositifs précédemment cités, la pression exercée sur le joint en position de fermeture est directement dépendante du réglage de la longueur du brin de traction avec les mêmes difficultés et inconvénients que ceux qui ont été énoncés pour les autres dispositifs de l'art antérieur.We also know according to US 1,974,151 or BE 349,584 articulated devices controlled by a cord or an integral chain by one of its ends of the frame carrying the hinges of the door. However, similarly to the aforementioned devices, the pressure exerted on the seal in the closed position is directly dependent on the adjustment of the length of the traction strand with the same difficulties and disadvantages than those that have been stated for other art devices prior.

Objet de l'inventionSubject of the invention

La présente invention propose un nouveau dispositif de commande pour un joint de porte automatique à translation verticale, dans lequel la contrainte exercée sur le joint dans sa position de travail est indépendante du moyen de commande du dispositif.The present invention provides a new control device for an automatic door seal with vertical translation, in which the stress exerted on the seal in its working position is independent of the device control means.

La présente invention a pour objet un joint pour bas de battant de porte, mobile en rotation par rapport à un dormant, du type comprenant un joint monté sur un support, un rail monté fixe sur le battant, au moins deux biellettes, chaque biellette est articulée à une extrémité sur un axe supérieur solidaire du rail et par l'autre extrémité sur un axe inférieur solidaire du support, caractérisé en ce qu'il comprend, en outre, un organe mobile qui est relié à une extrémité à un ressort de rappel prenant appui sur le rail et à l'autre extrémité à une sangle qui est fixée au dormant, de sorte que suivant le déplacement de l'organe mobile ladite sangle et ledit ressort de rappel commandent respectivement le relèvement et l'abaissement dudit joint.The present invention relates to a seal for the bottom of the leaf. door, movable in rotation relative to a frame, of the type comprising a joint mounted on a support, a rail mounted fixed on the leaf, at least two rods, each rod is articulated at one end on an upper axis secured to the rail and by the other end on a lower axis secured to the support, characterized in that it further comprises a movable member which is connected at one end to a return spring supported on the rail and at the other end with a strap which is fixed to the frame, so that following the movement of the movable member said strap and said return spring respectively command the raising and lowering of said seal.

DescriptionDescription

Le dispositif de commande du joint automatique à translation verticale fait appel à un joint en élastomère souple solidaire d'une baguette rigide articulée à l'aide d'au moins deux biellettes à l'intérieur d'un rail en U, au moins l'une des biellettes étant commandée par un tiroir coulissant et solidaire d'une part d'un ressort de rappel et d'aune part d'une sangle de traction dont l'autre extrémité peut être fixée au donnant de la porte par le moyen d'une came sur laquelle ladite sangle s'enroule partiellement lors de l'ouverture de la porte, provoquant ainsi une traction sur le tiroir et la rétraction du joint dans sa position relevée.The automatic translation joint control device vertical uses a flexible elastomer seal attached to a rod rigid articulated using at least two links inside a U-shaped rail, at least one of the links being controlled by a sliding drawer and secured on the one hand to a return spring and on the one hand to a strap traction, the other end of which can be fixed to the door opening by the by means of a cam on which said strap is partially wound when opening the door, causing traction on the drawer and retraction of the seal in its raised position.

Les dessins figurant en annexe permettent de mieux comprendre la description du dispositif selon l'invention.The attached drawings provide a better understanding of the description of the device according to the invention.

Les figures 5a et 5b sont respectivement des vues de face et en plan du système de fixation de la sangle dans le cas d'une porte à recouvrement.Figures 5a and 5b are front and plan views, respectively. of the strap fastening system in the case of an overlapping door.

La figure 6 est une vue schématique et de face d'une porte.Figure 6 is a schematic front view of a door.

Le joint automatique selon l'invention est destiné à équiper un bas de battant 1 qui est articulé sur un donnant 2 au moyen de gonds ou de paumelles 3 (figure 6).The automatic seal according to the invention is intended to equip a bottom leaf 1 which is articulated on a door 2 by means of hinges or hinges 3 (figure 6).

Le joint automatique selon l'invention et désigné dans son ensemble par la référence 4, comprend un joint 5 en élastomère souple, une baguette de support rigide 6 sur laquelle est monté le joint souple 5, un rail de maintien 7, en forme de U inversé et fixé sur la partie inférieure du battant 1, et au moins deux biellettes 8 et 8a, de préférence trois biellettes dont deux 8 sont prévues à proximité des côtés latéraux du battant, la troisième 8a étant disposée entre les deux biellettes latérales 8, chaque biellette étant articulée à une extrémité sur un axe supérieur 9, 9a solidaire du rail de maintien 7, et à l'autre extrémité sur un axe inférieur 10, 10a solidaire du support rigide 6 de joint souple 5.The automatic seal according to the invention and designated as a whole by reference 4, includes a seal 5 made of flexible elastomer, a rod of rigid support 6 on which the flexible seal 5 is mounted, a retaining rail 7, inverted U-shaped and fixed on the lower part of leaf 1, and at least two links 8 and 8a, preferably three links, two of which 8 are provided at proximity of the lateral sides of the leaf, the third 8a being disposed between the two lateral links 8, each link being articulated at one end on an upper axis 9, 9a integral with the retaining rail 7, and at the other end on a lower axis 10, 10a secured to the rigid support 6 of flexible joint 5.

Lorsque le rail 7 est fixé à la partie inférieure du battant 1 de porte, le joint peut passer d'une position haute à une position basse du fait de sa liaison au rail 7 par le moyen des biellettes 8, 8a qui forment un parallélogramme déformable avec le rail 7 et le support 6.When the rail 7 is fixed to the lower part of the door leaf 1, the seal can move from a high position to a low position due to its connection to rail 7 by means of links 8, 8a which form a deformable parallelogram with rail 7 and support 6.

Le moyen de commande selon l'invention pilote la position de l'une 8a des biellettes par le moyen d'un tiroir 11 qui se déplace horizontalement, parallèlement au rail de maintien 7. Le tiroir 11 est guidé, d'une part, par le rail 7 sur lequel il prend appui et, d'autre part, par l'axe supérieur 9a de la biellette commandée 8a sur lequel il peut se déplacer grâce à une première lumière 12 ou une encoche ménagée dans le tiroir 11, parallèlement au rail 7. Le déplacement de la biellette 8a commandé par le glissement du tiroir 11, est obtenu par le moyen d'un axe intennédiaire 13 solidaire de la biellette 8a qui coopère avec une deuxième lumière 14 ménagée dans le tiroir 11. La lumière 14 comprend une première partie ou zone 15 parallèle à la direction de translation du tiroir et une seconde partie ou zone 16 inclinée par rapport à l'axe de translation : lorsque l'axe intennédiaire 13 solidaire de la biellette 8a se trouve dans la première zone 15 de la lumière 14, la biellette 8a maintient le joint 5 dans une position levée. Lorsque le tiroir 11 est déplacé, le glissement de l'axe intermédiaire 13 dans la seconde zone 16 de la lumière 14 entraíne une rotation de la biellette 8a et l'abaissement du joint 5. La translation du tiroir 11 est commandée par, d'une part, l'action d'un ressort de rappel 17 qui prend appui sur le rail de maintien 7 et, d'autre part, une sangle ou tresse souple de traction 18. Le ressort 17 tend à rappeler le tiroir 11 dans une position selon laquelle le joint 5 est abaissé alors que la traction de la sangle 18, qui s'oppose à l'action du ressort 17, tend à tirer le tiroir 11 dans une position selon laquelle le joint est relevé (figures 1 et 2).The control means according to the invention controls the position of one 8a connecting rods by means of a drawer 11 which moves horizontally, parallel to the retaining rail 7. The drawer 11 is guided, on the one hand, by the rail 7 on which it is supported and, on the other hand, by the upper axis 9a of the controlled link 8a on which it can move thanks to a first light 12 or a notch in the drawer 11, parallel to the rail 7. The movement of the link 8a controlled by the sliding of the drawer 11 is obtained by means of an intermediate axis 13 secured to the link 8a which cooperates with a second light 14 made in the drawer 11. The light 14 comprises a first part or zone 15 parallel to the direction of translation of the drawer and a second part or zone 16 inclined relative to the translation axis: when the intermediate axis 13 secured to the link 8a is in the first zone 15 of the light 14, the link 8a maintains the seal 5 in a raised position. When the drawer 11 is moved, the sliding of the intermediate axis 13 in the second zone 16 of the light 14 drives a rotation of the link 8a and the lowering of the seal 5. The translation of the drawer 11 is controlled by, on the one hand, the action of a return spring 17 which is supported on the retaining rail 7 and, on the other hand, a strap or braid flexible traction 18. The spring 17 tends to return the drawer 11 in a position in which the seal 5 is lowered while the traction of the strap 18, which opposes the action of the spring 17, tends to pull the drawer 11 in a position in which the seal is raised (Figures 1 and 2).

Le mouvement de la sangle 18, dont une extrémité est fixée au tiroir 11, est obtenu en fixant l'autre extrémité au donnant 2 supportant les paumelles 3 de la porte, par le moyen d'une came 19 sur laquelle la sangle 18 va s'enrouler partiellement pendant la rotation du battant 1 autour des paumelles 3 (figures 4a à 5b).The movement of strap 18, one end of which is fixed to the drawer 11, is obtained by fixing the other end to the giving 2 supporting the door hinges 3, by means of a cam 19 on which the strap 18 will partially wind during the rotation of the leaf 1 around the hinges 3 (Figures 4a to 5b).

Pour des raisons esthétiques, l'ensemble du mécanisme est généralement recouvert par un capot protecteur 20 en matière plastique ou en métal. L'ensemble du dispositif est maintenu sur la porte au moyen de vis 21 que l'on fixe de préférence à l'intérieur des axes creux 9, 9a, ou au moyen d'un adhésif (figure 3). For aesthetic reasons, the entire mechanism is generally covered by a protective cover 20 made of plastic or metal. The entire device is held on the door by means of screws 21 which is preferably fixed inside the hollow axes 9, 9a, or by means adhesive (Figure 3).

Il est bien entendu que la longueur et la fonne des lumières 12 et 14 du tiroir 11, ainsi que le déport de la came 19 sont particulièrement importants pour définir les différents paramètres du mouvement du joint : en particulier la came 19 doit être profilée pour qu'une traction s'exerce sur la sangle 18 dès que le battant 7 de la porte quitte sa position de fenneture, et la zone inclinée 16 de la lumière 14 doit être orientée de façon à relever rapidement et immédiatement la biellette commandée 8a.It is understood that the length and the shape of the lights 12 and 14 of drawer 11, as well as the offset of cam 19 are particularly important to define the different parameters of the joint movement: in particular the cam 19 must be profiled so that traction is exerted on the strap 18 from that the leaf 7 of the door leaves its closing position, and the inclined zone 16 of the light 14 must be oriented so as to raise quickly and immediately the ordered link 8a.

Les figures 4a à 5b représentent le schéma de montage du joint automatique sur le battant 1 de la porte, et de la came 19 de commande qui doit être solidaire du dormant 2 de la porte supportant les paumelles 3.Figures 4a to 5b show the mounting diagram of the seal automatic on the leaf 1 of the door, and of the control cam 19 which must be fixed to the frame 2 of the door supporting the hinges 3.

La figure 4a représente le montage vu en plan dans le cas d'une porte plane affleurante 22 équipée du joint automatique selon l'invention. La sangle 18 est pincée sous la came 19 maintenue par des vis 23 sur le montant 24 supportant les paumelles 25. La figure 4b représente le montage précédent vu de face.FIG. 4a represents the assembly seen in plan in the case of a flush flat door 22 fitted with the automatic seal according to the invention. The strap 18 is pinched under cam 19 held by screws 23 on the upright 24 supporting the hinges 25. Figure 4b shows the previous assembly seen from the front.

Les figures 5a et 5b représentent respectivement les vues en plan et de face du montage du dispositif dans le cas d'une porte à recouvrement.FIGS. 5a and 5b respectively represent the plan views and front view of the device mounting in the case of an overlapping door.

Ainsi, selon ce montage, la rotation de la porte entre la position fermée et la position ouverte va entraíner une traction sur la sangle 18 provoquant une translation horizontale du tiroir 11 et par conséquent un mouvement vertical ascendant du joint 5. Pendant ce mouvement, le ressort 17 se tend sous la contrainte de la traction de la sangle 18.Thus, according to this arrangement, the rotation of the door between the position closed and the open position will cause traction on the strap 18 causing a horizontal translation of the drawer 11 and therefore a vertical upward movement of the joint 5. During this movement, the spring 17 tightens under the tensile stress of strap 18.

Lorsque l'on referme la porte, la traction de la sangle 18 est relâchée progressivement et le tiroir 11 se déplace sous l'effet du ressort 17 qui a été tendu précédemment ; pendant ce déplacement, la lumière 14 guide l'axe intermédiaire 13 solidaire de la biellette commandée 8a pour provoquer en fin de déplacement un abaissement du joint 5. En fin de manoeuvre de fermeture, le joint est en appui sur le sol du fait de son propre poids et de la tension résiduelle du ressort 17 : on s'aperçoit ainsi que la pression exercée sur le joint est préréglée par les caractéristiques du ressort 17 et ne dépend pas, à l'inverse des dispositifs à poussoirs connus, de réglages qui peuvent être approximatifs et varier dans le temps.When the door is closed, the pull of the strap 18 is gradually released and the drawer 11 moves under the effect of the spring 17 which has been stretched previously; during this movement, the light 14 guides the intermediate axis 13 secured to the controlled link 8a to cause at the end of movement, a lowering of the seal 5. At the end of the closure, the seal is supported on the ground due to its own weight and the residual tension of spring 17: this shows that the pressure exerted on the seal is preset by the characteristics of the spring 17 and does not depend, at the opposite of known push-button devices, adjustments which can be approximate and vary over time.

La réalisation pratique du joint automatique selon l'invention fait appel à des matériaux classiques habituellement utilisés pour ces appareils : le joint 5 est en élastomère souple tel que par exemple un caoutchouc nitrile, EPDM ou silicone ; le support 6 et le rail 7 sont en matériau rigide tel qu'un profilé aluminium ; les biellettes 8, 8a peuvent être en matériau de synthèse rigide ou en aluminium, le tiroir 11 peut être en acier ou en Nylon, le ressort 17 est de préférence en acier (on pourrait également utiliser une bande extensible en caoutchouc), la sangle 18 qui doit être souple et inextensible, est par exemple en polypropylène tressé, la came 19 est en matière rigide telle que par exemple du Nylon, de l'ABS ou de l'aluminium.The practical realization of the automatic seal according to the invention makes use of conventional materials usually used for these devices: seal 5 is made of flexible elastomer such as for example a nitrile rubber, EPDM or silicone; the support 6 and the rail 7 are made of rigid material such as aluminium section ; the links 8, 8a can be made of synthetic material rigid or aluminum, drawer 11 can be steel or nylon, the spring 17 is preferably made of steel (one could also use a strip rubber), the strap 18 which must be flexible and inextensible, is for example in braided polypropylene, the cam 19 is made of rigid material such as for example Nylon, ABS or aluminum.

La description du joint automatique ci-dessus a été faite pour un joint automatique articulé au moyen de biellettes. On peut également, sans sortir du domaine de l'invention, utiliser d'autres moyens de liaison entre la partie fixe et le joint mobile, tels que par exemple des lames flexibles ou des axes coulissants verticaux ; le dispositif de commande du mouvement vertical du joint qui, selon l'invention, fait toujours appel à la traction d'une sangle s'opposant à la force de rappel d'un ressort, est alors adapté en profilant le tiroir sous forme d'une lumière ou d'une came à glissement horizontal dont le déplacement sous l'effet de la sangle provoque la montée du joint par l'intermédiaire d'une tige rigide solidaire par une extrémité du support du joint et par son autre extrémité d'un axe coopérant avec la lumière ou la came du tiroir.The description of the automatic seal above was made for a automatic joint articulated by means of rods. We can also, without depart from the scope of the invention, use other means of connection between the fixed part and the movable joint, such as for example flexible blades or vertical sliding axes; the vertical motion control device of the seal which, according to the invention, always uses the traction of a strap opposing the return force of a spring, is then adapted by profiling the drawer in the form of a light or a horizontal sliding cam whose movement under the effect of the strap causes the seal to rise by through a rigid rod secured by one end of the joint support and by its other end of an axis cooperating with the light or the cam of the drawer.

Toujours sans sortir du domaine de l'invention, on peut obtenir le mouvement du joint en disposant sur le tiroir à translation horizontale un axe ou un ergot qui coopère avec une lumière ménagée dans la biellette commandée 8a.Still without departing from the scope of the invention, it is possible to obtain the movement of the joint by placing an axis on the horizontally translating drawer or a lug which cooperates with a light formed in the link ordered 8a.

La description qui précède a été faite pour un joint automatique à poser en applique sur la partie basse du battant d'une porte. L'homme de l'art pourra sans difficulté adapter le principe de fonctionnement de l'invention à un joint automatique qui serait intégré à l'intérieur de la base du battant de la porte, la sangle de manoeuvre passant dans ce cas par une fente ménagée dans le côté du battant.The above description was made for an automatic seal at apply on the lower part of the door leaf. The man of art can easily adapt the operating principle of the invention to an automatic seal which would be integrated inside the base of the leaf of the door, the operating strap in this case passing through a slot in the side of the leaf.

Le joint automatique selon l'invention présente l'avantage, par comparaison aux dispositifs connus de l'art antérieur, d'être dans sa position baissée alors qu'il est au repos, c'est à dire quand la sangle ne subit pas de traction et quand le ressort est dans sa contrainte minimale : cet avantage présente une importance notable car le joint peut être monté sur la porte alors que celle-ci est fermée : il suffit de présenter et d'appuyer le joint sur le sol puis de fixer le rail à l'aide des vis ; la sangle est ensuite pincée sous très faible tension, entre la came et le montant fixe de la porte côté paumelles et l'installation est faite sans qu'il ne soit nécessaire de faire des réglages ou de prendre des mesures.The automatic seal according to the invention has the advantage, by comparison with the known devices of the prior art, to be in its position lowered while it is at rest, i.e. when the strap does not undergo traction and when the spring is in its minimum stress: this advantage is of significant importance because the seal can be mounted on the door while that it is closed: just present and press the seal on the floor then fix the rail with screws; the strap is then pinched under very low tension, between the cam and the fixed amount of the door on the hinge side and installation is done without the need to make any adjustments or take measures.

Il est à noter également que la commande du dispositif nécessite une simple liaison côté paumelles de la porte et qu'aucun accessoire ne dépasse sur le côté serrure du battant de la porte.It should also be noted that ordering the device requires a simple connection on the hinge side of the door and that no accessories protrudes from the lock side of the door leaf.

Enfin, à l'inverse des dispositifs à poussoir ou levier actionneur, le dispositif n'offre aucune résistance à la fermeture de la porte. Il est même possible, dans le cas où cette fonction est recherchée, d'obtenir un couple de rappel de fermeture de la porte en adaptant la force du ressort et la forme de la came du dispositif décrit précédemment.Finally, unlike push-button or actuator lever devices, the device offers no resistance to closing the door. He is even possible, if this function is sought, to obtain a couple of door closing reminder by adjusting the spring force and the shape of the cam of the device described above.

Le joint automatique du bas de porte selon l'invention trouve son application essentiellement dans les bâtiments, où, en supprimant les courants d'air passant sous les portes, il permet d'améliorer le confort et d'économiser l'énergie.The automatic door bottom seal according to the invention finds its application mainly in buildings, where by removing currents air passing under the doors, it improves comfort and saves energy.
