Le vantail comprend une poutre inférieure prenant la forme d'un profilé creux, rectangulaire et ouvert vers le bas. Le dispositif d'entraînement comprend un moteur et un ensemble de galets d'entraînement. Le moteur relié au sol est placé à l'intérieur de la poutre inférieure et est mobile en rotation autour d'un axe de rotation orthogonal au plan de déplacement du vantail. Sur le moteur est monté l'ensemble de galets d'entraînement constitué de premiers galets supérieurs d'entraînement et de deuxièmes galets inférieurs d'entraînement qui sont mis en rotation par ledit moteur et qui roulent sur des voies de roulement respectivement supérieures et inférieures à la poutre inférieure. Afin d'assurer le contact entre les différents galets d'entraînement et les voies de roulement, les galets d'entraînement sont contraints contre lesdites voies de roulement par un couple de mise en pression qui agit sur le moteur.The patent EP-B-0 711 898 discloses a drive device of a gate leaf moving in a vertical plane when opening and closing the gate.

The characteristics of the invention mentioned above, as well as others, will appear more clearly on reading the following description of an example of embodiment, said description being made in connection with the accompanying drawings, among which:
  • the Fig. 1 represents a section of a leaf comprising a drive device according to the invention, by a plane orthogonal to the direction of movement of the leaf,
  • the Fig. 2 represents a section along line II-II of the Fig. 1 ,

  • FIG. 4 shows a detail of another embodiment of the invention.

La Fig. 1 représente un dispositif d'entraînement d'un vantail de portail 100.The Fig. 1 represents a drive device of a gate leaf 100.

Le vantail est constitué d'une poutre inférieure 102, d'une lisse et de barreaux verticaux 108 s'étendant entre la poutre inférieure 102 et la lisse. Le vantail se déplace horizontalement parallèlement à la direction longitudinale de la poutre inférieure 102. Le vantail se déplace, ainsi, dans un plan P qui est sensiblement vertical.The leaf consists of a lower beam 102, a smooth and vertical bars 108 extending between the lower beam 102 and the beam. The leaf moves horizontally parallel to the longitudinal direction of the lower beam 102. The leaf thus moves in a plane P which is substantially vertical.

La poutre infĂ©rieure 102 qui prend ici la forme d'un profilĂ© sensiblement rectangulaire, est creuse et munie d'une ouverture 126 orientĂ©e vers le bas et limitĂ©e par deux ailes horizontales 104a et 104b. La forme de la poutre infĂ©rieure 102 est dĂ©finie par les deux ailes 104a et 104b, deux parois latĂ©rales verticales et une paroi horizontale supĂ©rieure. Chaque aile 104a, 104b prĂ©sente une voie infĂ©rieure de roulement et une voie supĂ©rieure de roulement qui s'Ă©tendent dans la direction de dĂ©placement du vantail. Par convention, la face supĂ©rieure de chaque aile 104a, 104b est la face qui est orientĂ©e vers le haut et l'intĂ©rieur de la poutre infĂ©rieure 102, et la face infĂ©rieure de chaque aile 104a, 104b est la face qui est orientĂ©e vers le sol 110 et l'extĂ©rieur de la poutre infĂ©rieure 102. De mĂªme, une voie de roulement est dite infĂ©rieure lorsqu'elle est situĂ©e sur une face infĂ©rieure et une voie de roulement est dite supĂ©rieure lorsqu'elle est situĂ©e sur une face supĂ©rieure.The lower beam 102 which here takes the form of a substantially rectangular profile, is hollow and provided with an opening 126 oriented downwards and bounded by two horizontal flanges 104a and 104b. The shape of the lower beam 102 is defined by the two wings 104a and 104b, two vertical side walls and an upper horizontal wall. Each wing 104a, 104b has a lower raceway and an upper raceway which extend in the direction of movement of the leaf. By convention, the upper face of each wing 104a, 104b is the face which is oriented upwardly and inwardly of the lower beam 102, and the lower face of each wing 104a, 104b is the face which is oriented towards the ground 110 and the outside of the lower beam 102. Similarly, a raceway is said to be lower when it is located on a lower face and a raceway is said to be higher when it is located on an upper face.

L'ouverture 126 s'étend, de préférence, tout le long de la poutre inférieure 102. Le dispositif d'entraînement 100 comprend :

  • un chĂ¢ssis 114 reliĂ© au sol 110,
  • un moteur 106 fixĂ© au chĂ¢ssis 114 et disposĂ© Ă  l'intĂ©rieur de la poutre infĂ©rieure 102,
  • au moins un galet d'entraĂ®nement 120a, 120b entraĂ®nĂ© en rotation par le moteur 106 et en contact avec l'une des voies intĂ©rieures de roulement et,
  • un ensemble de trois paires de galets de guidage 116a, 116b, 118a, 118b et 214a fixĂ© au chĂ¢ssis 114. Le galet de guidage symĂ©trique du galet de guidage rĂ©fĂ©rencĂ© 214a n'est pas vu.
The opening 126 preferably extends all the way down the lower beam 102. The drive device 100 comprises:
  • a chassis 114 connected to the ground 110,
  • a motor 106 fixed to the frame 114 and disposed inside the lower beam 102,
  • at least one drive roller 120a, 120b rotated by the motor 106 and in contact with one of the inner raceways and,
  • a set of three pairs of guide rollers 116a, 116b, 118a, 118b and 214a fixed to the frame 114. The symmetrical guide roller of the guide roller 214a is not seen.

Comme cela est mieux vu sur la Fig. 2 et la Fig. 3, chacun des galets de guidage 118a et 118b de la première paire s'applique contre l'une des voies supérieures de roulement en amont du galet d'entraînement 120a, 120b.As is best seen on the Fig. 2 and the Fig. 3 , each of the guide rollers 118a and 118b of the first pair is applied against one of the upper raceways upstream of the drive roller 120a, 120b.

Chacun des galets de guidage 214a de la deuxième paire s'applique contre l'une des voies supérieures de roulement en aval du galet d'entraînement 120a, 120b.Each of the guide rollers 214a of the second pair is applied against one of the upper bearing tracks downstream of the drive roller 120a, 120b.

Chacun des galets de guidage 116a et 116b de la troisième paire s'applique contre l'une des voies inférieures de roulement entre l'un des galets de guidage 118a et 118b de la première paire et l'un des galets de guidage 214a de la deuxième paire.Each of the guide rollers 116a and 116b of the third pair is applied against one of the lower tracks of rolling between one of the guide rollers 118a and 118b of the first pair and one of the guide rollers 214a of the second pair.

Les positions amont et aval sont définies par référence à la direction de déplacement du vantail lors de son ouverture.The upstream and downstream positions are defined by reference to the direction of movement of the leaf when it is opened.

Un tel dispositif d'entraînement 100 dissocie la fonction de guidage de la poutre inférieure 102 et la fonction d'entraînement de la poutre inférieure 102. En effet, la fonction de guidage est assurée par les galets de guidage et la fonction d'entraînement est assurée par les galets d'entraînement 120a et 120b.Such a drive device 100 dissociates the guiding function of the lower beam 102 and the driving function of the lower beam 102. Indeed, the guiding function is provided by the guide rollers and the drive function is ensured by the drive rollers 120a and 120b.

Un tel dispositif d'entraĂ®nement 100 Ă©vite que le moteur 106 et, en particulier, l'axe des galets d'entraĂ®nement 120a et 120b ne subissent des efforts dus Ă  l'instabilitĂ© du vantail lors de son dĂ©placement. En effet, une contrainte due Ă  un dĂ©placement de la poutre 102 est reprise par les galets de guidage 116a, 116b, 118a, 118b et 214a et le chĂ¢ssis 114. La poutre infĂ©rieure 102 est ainsi maintenue Ă  une distance constante de l'axe de rotation des galets d'entraĂ®nement 120a et 120b, et ainsi, la pression exercĂ©e par le moteur 106 sur les voies supĂ©rieures de roulement reste sensiblement constante. Il n'est alors pas nĂ©cessaire d'appliquer une pression Ă©levĂ©e sur les voies supĂ©rieures de roulement et le risque de dĂ©formation de la poutre infĂ©rieure 102 est ainsi Ă©vitĂ©.Such a drive device 100 prevents the motor 106 and, in particular, the axis of the drive rollers 120a and 120b from being subjected to forces due to the instability of the leaf during its movement. Indeed, a constraint due to a displacement of the beam 102 is taken up by the guide rollers 116a, 116b, 118a, 118b and 214a and the frame 114. The lower beam 102 is thus maintained at a constant distance from the axis of the beam. rotation of the drive rollers 120a and 120b, and thus the pressure exerted by the motor 106 on the upper tracks of rolling remains substantially constant. It is then not necessary to apply a high pressure on the upper tracks of bearing and the risk of deformation of the lower beam 102 is thus avoided.

Afin d'amĂ©liorer le guidage de la poutre infĂ©rieure 102, une quatrième paire de galets de guidage 216a et 216b est fixĂ©e au chĂ¢ssis 114 et chacun des galets de guidage 216a et 216b de la quatrième paire s'applique contre l'une des voies infĂ©rieures de roulement de l'autre cĂ´tĂ© du galet d'entraĂ®nement 120a, 120b par rapport Ă  chacun des galets de guidage 116a et 116b de la troisième paire. En d'autres termes, la troisième paire de galets de guidage 116a et 116b et la quatrième paire de galets de guidage 216a, 216b sont disposĂ©es de part et d'autre des galets d'entraĂ®nement 120a et 120b.In order to improve the guidance of the lower beam 102, a fourth pair of guide rollers 216a and 216b is attached to the frame 114 and each of the guide rollers 216a and 216b of the fourth pair is applied against one of the lower channels. rolling on the other side of the drive roller 120a, 120b relative to each of the guide rollers 116a and 116b of the third pair. In other words, the third pair of guide rollers 116a and 116b and the fourth pair of guide rollers 216a, 216b are disposed on either side of the drive rollers 120a and 120b.

Dans le mode de réalisation de l'invention décrit ici, la troisième paire de galets de guidage 116a et 116b est disposée en amont des galets d'entraînement 120a et 120b et la quatrième paire de galets de guidage 216a et 216b est disposée en aval des galets d'entraînement 120a et 120b, mais il est possible d'intervertir la position de chacune d'elles.In the embodiment of the invention described here, the third pair of guide rollers 116a and 116b is disposed upstream of the drive rollers 120a and 120b and the fourth pair of guide rollers 216a and 216b is disposed downstream of the drive rollers 120a and 120b, but it is possible to invert the position of each of them.

PrĂ©fĂ©rentiellement, l'axe de rotation de l'un des galets de guidage 116a, 116b, 118a, 118b, 214a, 216a et 216b d'une paire est confondu avec l'axe de rotation de l'autre galet de guidage 116b, 116a, 118b, 118a, 214a, 216b et 216a de la mĂªme paire.Preferably, the axis of rotation of one of the guide rollers 116a, 116b, 118a, 118b, 214a, 216a and 216b of one pair coincides with the axis of rotation of the other guide roller 116b, 116a , 118b, 118a, 214a, 216b and 216a of the same pair.

Le chĂ¢ssis 114 comprend un chĂ¢ssis infĂ©rieur 128 et un chĂ¢ssis supĂ©rieur sous forme d'un pilier avant 124 et d'un pilier arrière 226. Le chĂ¢ssis 114 est reliĂ© au sol 110 par l'intermĂ©diaire d'une liaison rotule 208 qui permet au chĂ¢ssis 114 de se dĂ©battre angulairement sous l'effet des contraintes qu'exerce la poutre infĂ©rieure 102, sur le chĂ¢ssis 114, lors de son dĂ©placement.The frame 114 comprises a lower frame 128 and an upper frame in the form of a front pillar 124 and a rear pillar 226. The frame 114 is connected to the ground 110 via a ball joint 208 which allows the frame 114 to struggle angularly under the effect of the constraints exerted by the lower beam 102 on the frame 114, during its displacement.

Par exemple, le débattement angulaire peut s'effectuer autour d'un axe de rotation référencé 210 et autour d'un axe de rotation référencé 211. L'axe de rotation 210 est sensiblement orthogonal au plan P et le débattement associé est représentatif d'une rotation du vantail autour d'un axe parallèle à l'axe de rotation 210. L'axe de rotation 211 est sensiblement horizontal et le débattement associé est représentatif d'un basculement du vantail de part et d'autre du plan P.For example, the angular displacement can be performed around an axis of rotation referenced 210 and around an axis of rotation referenced 211. The axis of rotation 210 is substantially orthogonal to the plane P and the associated movement is representative of a rotation of the leaf about an axis parallel to the axis of rotation 210. The axis of rotation 211 is substantially horizontal and the associated movement is representative of a tilting of the leaf on both sides of the plane P.

Dans le mode de rĂ©alisation de l'invention reprĂ©sentĂ© Ă  la Fig. 2, le chĂ¢ssis infĂ©rieur 128 est reliĂ© au sol 110 par l'intermĂ©diaire d'un pied de fixation 240. Le pied de fixation 240 comprend une base 112, une colonne 202, un bras 206 et la rotule 208. La base 112 est fixĂ©e au sol 110. La colonne 202 s'Ă©tend verticalement depuis la base 112. Le bras 206 s'Ă©tend sensiblement horizontalement depuis le sommet de la colonne 202 auquel il est liĂ© par l'une de ses extrĂ©mitĂ©s Ă  l'aide d'une liaison pivot dont l'axe de rotation 204 est orthogonal au plan P. L'autre extrĂ©mitĂ© du bras 206 est liĂ©e Ă  la rotule 208 qui est elle-mĂªme fixĂ©e sur le chĂ¢ssis infĂ©rieur 128. L'axe de rotation 204 autorise le libre dĂ©placement vertical du dispositif d'entraĂ®nement 100 lorsque la poutre infĂ©rieure 102 monte ou descend verticalement.In the embodiment of the invention shown in Fig. 2 , the lower frame 128 is connected to the ground 110 by means of a fixing foot 240. The fixing foot 240 comprises a base 112, a column 202, an arm 206 and the ball 208. The base 112 is fixed to The column 202 extends vertically from the base 112. The arm 206 extends substantially horizontally from the top of the column 202 to which it is connected by one of its ends by means of a pivot connection. whose axis of rotation 204 is orthogonal to the plane P. The other end of the arm 206 is connected to the ball joint 208 which is itself fixed on the lower frame 128. The axis of rotation 204 allows the free vertical movement of the driving device 100 when the lower beam 102 ascends or descends vertically.

Afin de s'assurer que la pression exercée par les galets d'entraînement 120a et 120b sur les voies supérieures de roulement ne soit ni trop forte au risque de détériorer le moteur 106 ou les galets d'entraînement 120a et 120b ni trop faible au risque que les galets d'entraînement 120a et 120b n'entraînent plus la poutre inférieure 102, le dispositif d'entraînement 100 comprend des moyens de réglage. Les moyens de réglage sont prévus pour, ajuster la pression de chaque galet d'entraînement 120a, 120b contre la voie supérieure de roulement correspondante.In order to ensure that the pressure exerted by the drive rollers 120a and 120b on the upper raceways is neither too high, with the risk of damaging the motor 106 or the drive rollers 120a and 120b, nor too weak at risk that the drive rollers 120a and 120b no longer drive the lower beam 102, the drive device 100 comprises adjusting means. The means of Adjustments are provided to adjust the pressure of each drive roller 120a, 120b against the corresponding upper track.

Les moyens de rĂ©glage permettent Ă©galement de dĂ©brayer le dispositif d'entraĂ®nement 100 en relĂ¢chant la pression que chaque galet d'entraĂ®nement 120a, 120b exerce contre la voie supĂ©rieure de roulement correspondante. Ce dĂ©brayage permet le dĂ©placement manuel du vantail sans qu'il soit nĂ©cessaire de faire fonctionner le moteur 106.The adjustment means can also disengage the drive device 100 by releasing the pressure that each drive roller 120a, 120b exerts against the corresponding upper raceway. This clutch allows the manual movement of the leaf without the need to operate the engine 106.

Selon un mode de réalisation particulier de l'invention, les moyens de réglage comprennent :

  • une platine 218 solidaire du moteur 106, la platine 218 Ă©tant montĂ©e libre en rotation autour d'un axe de rotation 310
    parallèle à l'axe de rotation des galets d'entraînement 120a et 120b et,
  • un dispositif de rĂ©glage de l'angle de rotation 250 prĂ©vu pour rĂ©gler l'angle de rotation de ladite platine 218.
According to a particular embodiment of the invention, the adjustment means comprise:
  • a plate 218 integral with the motor 106, the plate 218 being mounted free to rotate about an axis of rotation 310
    parallel to the axis of rotation of the drive rollers 120a and 120b and,
  • a rotation angle adjusting device 250 provided for adjusting the angle of rotation of said plate 218.

Selon le sens de rotation de la platine 218, les galets d'entraînement 120a et 120b s'éloignent ou se rapprochent des voies supérieures de roulement, assurant ainsi, respectivement, la diminution ou l'augmentation de la pression qu'exercent les galets d'entraînement 120a et 120b sur les voies supérieures de roulement.According to the direction of rotation of the plate 218, the drive rollers 120a and 120b move away from or approach the upper tracks of rolling, thus ensuring, respectively, the decrease or the increase of the pressure exerted by the rollers of 120a and 120b drive on the upper tracks of rolling.

Selon un mode de réalisation particulier de l'invention et afin de faciliter la réalisation du dispositif d'entraînement 100, l'axe de rotation 310 de la platine 218 est confondu avec l'axe de rotation de l'une des paires de galets de guidage 216a, 216b s'appliquant contre l'une des voies inférieures de roulement. Il s'agit, en l'occurrence, de la quatrième paire de galets de guidage 216a et 216b disposée en aval des galets d'entraînement 120a et 120b mais, dans un autre mode de réalisation de l'invention, il peut s'agir de la troisième paire de galets de guidage 116a et 116b disposée en amont des galets d'entraînement 120a et 120b.According to a particular embodiment of the invention and in order to facilitate the production of the driving device 100, the axis of rotation 310 of the plate 218 coincides with the axis of rotation of one of the pairs of rollers of guiding 216a, 216b applying against one of the lower tracks of rolling. This is, in this case, the fourth pair of guide rollers 216a and 216b disposed downstream of the drive rollers 120a and 120b but, in another embodiment of the invention, it may be of the third pair of guide rollers 116a and 116b disposed upstream of the drive rollers 120a and 120b.

Le dispositif de réglage de l'angle de rotation 250 comprend un élément en U 220, une molette 308, une rondelle 304, une goupille 222 et un plot 226.The rotation angle adjusting device 250 comprises a U-shaped element 220, a wheel 308, a washer 304, a pin 222 and a stud 226.

Le plot 226, de préférence cylindrique, est solidaire de la platine 218 et s'étend orthogonalement au plan P.The pad 226, preferably cylindrical, is integral with the plate 218 and extends orthogonally to the plane P.

L'élément en U 220 comprend une partie inférieure qui est percée et filetée et une partie supérieure en U. La platine 218 est placée dans la partie supérieure en U qui est percée d'un trou oblong 224 dans lequel est inséré le plot 226.The U-shaped element 220 comprises a lower part which is pierced and threaded and a U-shaped upper part. The plate 218 is placed in the U-shaped upper part which is pierced with an oblong hole 224 in which the pad 226 is inserted.

La goupille 222 est solidaire de l'Ă©lĂ©ment en U 220 et coopère avec une rainure verticale 228 du chĂ¢ssis 114.The pin 222 is integral with the U-shaped element 220 and cooperates with a vertical groove 228 of the frame 114.

La molette 308 comprend une poignée afin de faciliter sa prise en main et une tige filetée 306 qui est prévue pour coopérer avec le filetage de l'élément en U 220.The wheel 308 comprises a handle to facilitate its grip and a threaded rod 306 which is provided to cooperate with the thread of the U-shaped element 220.

La rondelle 304 est solidaire du chĂ¢ssis 114 et est percĂ©e d'un trou dans lequel est insĂ©rĂ©e la tige filetĂ©e 306. La rondelle 304 est alignĂ©e avec un alĂ©sage 320 rĂ©alisĂ© dans le chĂ¢ssis 114.The washer 304 is secured to the frame 114 and is pierced with a hole in which is inserted the threaded rod 306. The washer 304 is aligned with a bore 320 formed in the frame 114.

La molette 308 est munie d'une rainure circulaire dans laquelle vient s'insérer la rondelle 304, ce qui a pour effet de bloquer en translation la tige filetée 306 tout en la laissant libre en rotation.The wheel 308 is provided with a circular groove in which is inserted the washer 304, which has the effect of locking in translation the threaded rod 306 while leaving it free in rotation.

L'élément en U 220 est inséré dans l'alésage 320 et il est vissé sur la tige filetée 306.The U-shaped member 220 is inserted into the bore 320 and is threaded onto the threaded rod 306.

Afin de déplacer angulairement la platine 218 et par conséquent le moteur 106, un utilisateur fait tourner la molette 308.In order to angularly move the plate 218 and therefore the motor 106, a user rotates the wheel 308.

La rotation de la molette 308 et par conséquent de la tige filetée 306 fait monter ou descendre l'élément en U 220. En effet, celui-ci ne peut pas tourner du fait de la présence de la goupille 222 qui coopère avec la rainure 228.The rotation of the wheel 308 and therefore of the threaded rod 306 raises or lowers the U-shaped element 220. Indeed, it can not rotate due to the presence of the pin 222 which cooperates with the groove 228. .

La montée ou la descente de l'élément en U 220 entraîne la montée ou la descente du plot 226 et par conséquent le basculement de la platine 218 autour de son axe de rotation 310.Raising or lowering the U-shaped element 220 causes the pad 226 to rise or fall, and consequently the plate 218 to tilt about its axis of rotation 310.

Le trou oblong 224 permet le libre déplacement du plot 226 dans la platine 218 lors du basculement de celle-ci.The oblong hole 224 allows the free movement of the pad 226 in the plate 218 during the tilting thereof.

La Fig. 4 représente un autre mode de réalisation du dispositif de réglage de l'angle de rotation.Fig. 4 shows another embodiment of the angle of rotation adjustment device.

Le dispositif de rĂ©glage de l'angle de rotation est,ici, constituĂ© d'une vis 402 qui se visse dans le chĂ¢ssis infĂ©rieur 128. La tĂªte de la vis se retrouve alors sous le chĂ¢ssis infĂ©rieur 128 de la mĂªme manière que la molette 308 et l'arbre de la vis vient appuyer sous la platine 218. En vissant plus ou moins la vis 402, les galets d'entraĂ®nement 120a et 120b viendront plus ou moins en pression contre les voies supĂ©rieures de roulement.The rotation angle adjusting device is here constituted by a screw 402 which is screwed into the lower frame 128. The head of the screw is then found under the lower frame 128 in the same manner as the wheel 308 and the shaft of the screw is pressed under the plate 218. By screwing more or less the screw 402, the drive rollers 120a and 120b will come more or less in pressure against the upper tracks of rolling.

Afin d'autoriser, un léger phénomène de suspension, un dôme 408 est monté sur l'extrémité de l'arbre de la vis 402 et est soumis à l'action d'un ressort 406 qui vient pousser le dôme 408 contre la platine 218. Afin de guider transversalement la platine 218, une cavité 404 est prévue sous la platine 218. La cavité 404 vient s'emmancher sur l'arbre de la vis 402.In order to allow a slight suspension phenomenon, a dome 408 is mounted on the end of the shaft of the screw 402 and is subjected to the action of a spring 406 which pushes the dome 408 against the plate 218 In order to guide the plate 218 transversely, a cavity 404 is provided under the plate 218. The cavity 404 is engaged on the shaft of the screw 402.

Afin de prévenir tout problème de parallélisme entre les galets d'entraînement 120a et 120b et les voies supérieures de roulement, la platine 218 est montée sur l'arbre de rotation 310 par l'intermédiaire d'une rotule qui permet un léger débattement de la platine autour de son axe de rotation 310. La rotule prend la forme d'une bille centrée et solidaire de l'arbre de rotation 310 et elle est enfermée dans un évidement réalisé dans la platine 218.In order to prevent any problem of parallelism between the drive rollers 120a and 120b and the upper tracks of rolling, the plate 218 is mounted on the rotation shaft 310 by means of a ball joint which allows a slight deflection of the platinum about its axis of rotation 310. The ball takes the form of a ball centered and integral with the rotation shaft 310 and is enclosed in a recess formed in the plate 218.

Pour aider le chĂ¢ssis 114 Ă  accompagner le dĂ©battement angulaire du vantail autour du plan P, le dispositif d'entraĂ®nement 100 comprend, avantageusement, au moins une paire de galets d'alignement 122a, 122b, 212a, 212b fixĂ©e au chĂ¢ssis 114 et disposĂ©e Ă  l'intĂ©rieur de la poutre infĂ©rieure 102, l'un des galets d'alignement 122a, 122b, 212a, 212b d'une paire s'appliquant contre l'une des parois latĂ©rales verticales de la poutre infĂ©rieure 102 et l'autre galet d'alignement 122b, 122a, 212b, 212a de la mĂªme paire s'appliquant contre l'autre paroi latĂ©rale verticale de la poutre infĂ©rieure 102.To help the frame 114 to accompany the angular deflection of the leaf around the plane P, the drive device 100 advantageously comprises at least one pair of alignment rollers 122a, 122b, 212a, 212b fixed to the frame 114 and arranged at the interior of the lower beam 102, one of the alignment rollers 122a, 122b, 212a, 212b of a pair applying against one of the vertical side walls of the lower beam 102 and the other roller 122b, 122a, 212b, 212a of the same pair applying against the other vertical side wall of the lower beam 102.

Selon un mode de réalisation particulier de l'invention représenté sur les Figs., le dispositif d'entraînement 100 comprend au moins deux paires de galets d'alignement 122a, 122b, 212a, 212b, l'une d'elle étant disposée en amont des galets d'entraînement 120a et 120b et l'autre étant disposée en aval des galets d'entraînement 120a et 120b.According to a particular embodiment of the invention shown in Figs., The drive device 100 comprises at least two pairs of alignment rollers 122a, 122b, 212a, 212b, one of them being arranged upstream drive rollers 120a and 120b and the other being disposed downstream of the drive rollers 120a and 120b.

Dans le mode de réalisation de l'invention représenté sur les Figs., les galets d'alignement 122a et 122b disposés en amont sont fixés sur le pilier avant 124 et les galets d'alignement 212a et 212b disposés en aval sont fixés sur le pilier arrière 226.In the embodiment of the invention shown in Figs., The alignment rollers 122a and 122b arranged upstream are fixed on the front pillar 124 and the alignment rollers 212a and 212b disposed downstream are fixed on the pillar rear 226.

Le dispositif d'entraînement 100 peut s'appliquer dans le cas d'un vantail autoportant ou non.The drive device 100 can be applied in the case of a self-supporting leaf or not.

Dans le cas d'un vantail autoportant, la colonne 202 peut se prolonger Ă  l'intĂ©rieur de la poutre infĂ©rieure 102 par un mĂ¢t 232 (en traits mixtes) qui porte un galet de support 230 (en traits mixtes) qui s'insère dans l'espace dĂ©fini Ă  l'intĂ©rieur de la poutre infĂ©rieure 102 entre les ailes 104a et 104b et la paroi supĂ©rieure de la poutre infĂ©rieure 102. D'une manière gĂ©nĂ©rale, lorsque le vantail est autoportant, le dispositif de fixation au sol 110 du chĂ¢ssis 114, ici la colonne 202, se prolonge Ă  l'intĂ©rieur de la poutre infĂ©rieure 102 et porte le galet de support 230.In the case of a self-supporting leaf, the column 202 can extend inside the lower beam 102 by a mast 232 (in phantom) which carries a support roller 230 (in phantom) which fits into the space defined inside the lower beam 102 between the flanges 104a and 104b and the upper wall of the lower beam 102. In general, when the leaf is self-supporting, the ground fixing device 110 of the frame 114, here the column 202, extends inside the lower beam 102 and carries the support roller 230.

Bien entendu, la présente invention n'est pas limitée aux exemples et modes de réalisation décrits et représentés, mais elle est susceptible de nombreuses variantes accessibles à l'homme de l'art.Of course, the present invention is not limited to the examples and embodiments described and shown, but it is capable of many variants accessible to those skilled in the art.

En particulier, il peut exister un jeu fonctionnel entre les ailes et les galets de guidage qui est tel que les contacts entre les ailes et les diffĂ©rents galets de guidage peuvent ne pas Ăªtre simultanĂ©ment assurĂ©s. Ce jeu fonctionnel reste suffisamment faible pour garantir que les efforts qui s'exercent sur le moteur restent limitĂ©s.In particular, there may be a functional clearance between the wings and the guide rollers which is such that the contacts between the wings and the different guide rollers may not be simultaneously ensured. This functional game remains weak enough to guarantee that the efforts exerted on the engine remain limited.
