Description

La présente invention concerne une porte de manutention à rideau relevabIe et vise plus particulièrement une porte préfabriquée pour mise en place simplifiée. Les portes de ce type comportent généralement un cadre formé de deux montants latéraux verticaux et d'une traverse supérieure. Les montants latéraux supportent la traverse et forment ou contiennent des glissières pour les bords du rideau. Ils sont fixés au sol et leurs extrémités inférieures sont ainsi maintenues. La traverse supérieure sert à maintenir l'écartement entre les montants à leurs extrémités supérieures et à abriter la mécanique. Elle renferme un arbre d'enroulement, soit du rideau lui-même si c'est le rideau que l'on enroule, soit de sangles de relevage si le rideau se replie en accordéon à la partie supérieure de la porte. La traverse supérieure peut contenir en outre des paliers pour supporter ledit arbre, un moteur électrique, des accessoires tels qu'un fin de course, des commandes automatiques, etc.The present invention relates to a lifting curtain curtain door and more particularly relates to a prefabricated door for simplified installation. Doors of this type generally have a frame formed by two vertical lateral uprights and an upper cross member. The lateral uprights support the crossmember and form or contain slides for the edges of the curtain. They are fixed to the ground and their lower ends are thus maintained. The upper crosspiece is used to maintain the spacing between the uprights at their upper ends and to house the mechanics. It contains a winding shaft, either of the curtain itself if it is the curtain that is rolled up, or of lifting straps if the curtain folds like an accordion at the top of the door. The upper crossmember can also contain bearings to support said shaft, an electric motor, accessories such as a limit switch, automatic controls, etc.

La présente invention a pour but de réaliser un montage simplifié d'une telle porte. En particulier, l'invention a pour but de rationnaliser les constituants, d'en limiter le nombre et d'accélérer la mise en place et la mise en fonctionnement de la porte.The present invention aims to achieve a simplified mounting of such a door. In particular, the invention aims to rationalize the constituents, limit the number and accelerate the establishment and operation of the door.

L'invention a pour objet une porte de manutention à rideau relevable, du type comportant un arbre d'enroulement à la partie supérieure et des montants latéraux verticaux formant ou contenant des glissières pour les bords du rideau, lesdits montants verticaux ayant leurs extrémités inférieures fixées au sol, caractérisée en ce que chaque montant latéral comporte, à sa partie supérieure, un organe pour recevoir et supporter de façon détachable l'arbre d'enroulement. Ceci permet de loger les éléments moteurs et de transmission dans les montants. Avantageusement, l'arbre est monté de façon qu'il empêche les extrémités supérieures des montants de se rapprocher, et en ce qu'un élément résistant en traction tel qu'une entretoise est tendu entre les extrémités supérieures des montants pour les empêcher de s'écarter. Comme les éléments mécaniques sont logés dans les montants, la traverse du portique d'encadrement de la porte est virtuellement supprimée.The subject of the invention is a lifting door with a lifting curtain, of the type comprising a winding shaft at the top and vertical lateral uprights forming or containing slides for the edges of the curtain, said vertical uprights having their lower ends fixed. on the ground, characterized in that each lateral upright comprises, at its upper part, a member for detachably receiving and supporting the winding shaft. This allows the engine and transmission elements to be housed in the uprights. Advantageously, the shaft is mounted so that it prevents the upper ends of the uprights from coming together, and in that a tensile-resistant element such as a spacer is stretched between the upper ends of the uprights to prevent them from s 'dismiss. As the mechanical elements are housed in the uprights, the cross member of the gantry for the door frame is virtually eliminated.

Dans ces conditions, pour mettre en place une porte selon l'invention, on peut par exemple placer contre le mur qui limite une baie, de chaque côté de celle-ci, un montant latéral ; on place l'arbre d'enroulement entre les montants pour les maintenir écartés. Pour cela, chaque montant portant un bout d'arbre, il faut engager l'arbre d'enroulement sur les deux bouts d'arbre, à chacune de ses extrémités. Il suffit pour y parvenir, que l'un des bouts d'arbre soit déplaçable et puisse être rentré dans le montant afin que l'on mette l'arbre d'enroulement en alignement sur ce bout d'arbre, qu'ensuite on enfonce dans l'arbre. Le bout d'arbre assure la liaison en rotation et supporte l'arbre. Une bonne façon de réaliser cette opération consiste à prévoir, dans la partie supérieure de chaque montant, un bloc contenant des éléments mécaniques tel qu'un réducteur, dont un arbre de sortie constitue ledit bout d'arbre. Le réducteur est mis en place provisoirement, sans être vissé ou boulonné. Il peut être reculé lorsque que l'on approche l'arbre, puis repoussé pour que le bout d'arbre s'engage dans l'arbre d'enroulement, et finalement vissé ou boulonné en position définitive. L'opération est très simple.Under these conditions, to set up a door according to the invention, one can for example place against the wall which limits a bay, on each side thereof, a lateral upright; the winding shaft is placed between the uprights to keep them apart. For this, each upright carrying a shaft end, it is necessary to engage the winding shaft on the two shaft ends, at each of its ends. To achieve this, it suffices that one of the ends of the shaft is movable and can be retracted into the upright so that the winding shaft is brought into alignment with this end of the shaft, which is then pressed in the tree. The shaft end provides the rotational connection and supports the shaft. A good way to do this is to plan, in the upper part of each upright, a block containing mechanical elements such as a reduction gear, an output shaft of which constitutes said end of the shaft. The gear unit is temporarily installed, without being screwed or bolted. It can be moved back when approaching the tree, then pushed back so that the end of the shaft engages in the winding shaft, and finally screwed or bolted in the final position. The operation is very simple.

De préférence, chaque montant comporte un réducteur mécanique accouplé d'un côté à l'arbre d'enroulement. A l'autre côté du réducteur mécanique, l'un des montants comporte un moteur électrique pour faire tourner l'arbre d'enroulement et l'autre montant comporte un fin de course, pour commander l'arrêt du moteur, en fin de lever ou de baisser du rideau (certains fins de course peuvent fonctionner sans réducteur; dans ce cas là bien évidemment, il n'y en a pas).Preferably, each upright comprises a mechanical reducer coupled on one side to the winding shaft. On the other side of the mechanical reduction gear, one of the uprights has an electric motor to rotate the winding shaft and the other upright has a limit switch, to stop the motor, at the end of lifting or lower the curtain (some limit switches can operate without a gearbox; in this case, of course, there is none).

D'autres caractéristiques et avantages de l'invention apparaîtront au cours de la description qui va suivre, donnée à titre d'exemple non limitatif, en regard des dessins joints, et qui fera bien comprendre comment l'invention peut être réalisée.Other characteristics and advantages of the invention will appear during the description which follows, given by way of nonlimiting example, with reference to the accompanying drawings, and which will make it clear how the invention can be implemented.

  • Figure 3 is an elevational view, front of the door, the amount of Figure 1, that is to say seen in a plane perpendicular to the first.

La porte selon l'invention comporte deux montants latéraux verticaux, de structures symétriques, comportant chacun à une extrémité inférieure des moyens de fixation au sol, et à l'autre extrémité supérieure un coffre d'où sort une connexion d'arbre d'enroulement, et dans le coffre, un réducteur de vitesse, et pour un montant un moteur électrique, et pour l'autre un fin de course.The door according to the invention comprises two vertical lateral uprights, of symmetrical structures, each comprising at a lower end means for fixing to the ground, and at the other upper end a box from which comes out a winding shaft connection. , and in the trunk, a speed reducer, and for an upright an electric motor, and for the other a limit switch.

Dans un mur 1 est découpée une baie 2 et cette baie peut être obturée ou dégagée grâce à une porte de manutention à rideau relevable. Cette porte est constituée d'un rideau souple renforcé à intervalles par des barres horizontales, et de deux montants symétriques dont un seul est représenté en 3 sur les dessins. Chaque montant est constitué d'une pièce métallique en forme de U, pouvant être réalisée par une tole pliée. Cette forme confère une résistance au montant et lui permet d'assurer la fonction de glissière, ou de contenir une glissière, pour les bords du rideau et les bouts des barres de renforcement horizontales de ce rideau. Chaque montant est muni à sa base d'une semelle 4 fixée convenablement au sol, par exemple par des boulons 5. Les montants peuvent en outre être fixés au mur 1, comme schématisé en 6, à toute hauteur appropriée.In a wall 1 is cut a bay 2 and this bay can be closed or cleared thanks to a lifting curtain door. This door consists of a flexible curtain reinforced at intervals by horizontal bars, and two symmetrical uprights, only one of which is shown in 3 in the drawings. Each upright consists of a U-shaped metal part, which can be produced by a folded sheet. This form gives resistance to the upright and allows it to perform the function of a slide, or to contain a slide, for the edges of the curtain and the ends of the horizontal reinforcing bars of this curtain. Each upright is provided at its base with a sole 4 properly fixed to the ground, for example by bolts 5. The uprights can also be fixed to wall 1, as shown in diagram 6, at any suitable height.

Le rideau peut être enroulé à la partie supérieure sur un arbre 7. En variante, l'arbre 7 peut enrouler des sangles 8, accrochées à la barre inférieure 9 de renforcement du rideau, et passant dans des anneaux 10, fixés aux barres de renforcement supérieures 11. Sur la figure 3, seule une sangle est représentée, sans rideau ni barres, puisque cette structure est bien connue. Le rideau est accroché à une barre d'accrochage 111 le long de son bord supérieur et peut être relevé par pliage en accordéon à la partie supérieure quand les sangles de relevage 8 sont enroulées sur l'arbre 7.The curtain can be wound at the top on a shaft 7. As a variant, the shaft 7 can wind straps 8, hooked to the lower bar 9 for reinforcing the curtain, and passing through rings 10, fixed to the reinforcement bars. 11. In FIG. 3, only one strap is shown, without curtain or bars, since this structure is well known. The curtain is hung on a hanging bar 111 along its upper edge and can be raised by accordion folding at the upper part when the lifting straps 8 are wound on the shaft 7.

A la partie supérieure de chaque montant est fixé, sur un élément support approprié tel qu'une plaque 12, un bloc mécanique 13 comportant un réducteur, dont un côté est connecté à un bout d'arbre 14, et l'autre côté à un moteur électrique 15 sur un montant, ou un fin de course sur l'autre montant.At the upper part of each upright is fixed, on a suitable support element such as a plate 12, a mechanical block 13 comprising a reduction gear, one side of which is connected to a shaft end 14, and the other side to a electric motor 15 on one upright, or a limit switch on the other upright.

L'arbre 7 est engagé sur des deux bouts d'arbre 14 (sur la figure 3, un seul est représenté, l'autre étant symétrique). La connexion entre le bout de l'arbre 4 et l'arbre 7 assure la liaison en rotation et le support de l'arbre. L'arbre 7 empêche également les montants de se rapprocher à leurs parties supérieures, ce qui peut paraître surabondant si les montants sont bien fixés à la maçonnerie du mur. En tous cas, cela garantit contre le travail du bâtiment, les affaissements, etc.. Selon l'invention, il est également prévu, pour empêcher les montants de s'écarter et pour protéger l'arbre et le rideau, de placer au-dessus, s'étendant d'un montant à l'autre, une entretoise 20 en forme de capot, qui est fixée sur les sommets des montants latéraux une fois que ceux-ci ont été mis en place. Cette entretoise peut aussi servir à y accrocher le rideau (dans le cas où le rideau ne s'enroule pas), notamment si le rideau, dont les coins sont attachés aux montants, doit obturer une baie d'assez grande portée. Cela dispense d'une barre d'accrochage. Cette entretoise peut être boulonnée, éventuellement soudée aux montants verticaux latéraux (la soudure rend le démontage moins facile).The shaft 7 is engaged on two ends of the shaft 14 (in FIG. 3, only one is shown, the other being symmetrical). The connection between the end of the shaft 4 and the shaft 7 provides the rotational connection and the support of the shaft. The shaft 7 also prevents the uprights from approaching their upper parts, which may seem overabundant if the uprights are well fixed to the masonry of the wall. In any case, this guarantees against building work, sagging, etc. According to the invention, it is also provided, to prevent the uprights from spreading and to protect the tree and the curtain, to place at- above, extending from one upright to another, a spacer 20 in the form of a hood, which is fixed to the tops of the lateral uprights once these have been put in place. This spacer can also be used to hang the curtain there (in the case where the curtain does not roll up), especially if the curtain, whose corners are attached to the uprights, must close off a fairly large span. This dispenses with a hanging bar. This spacer can be bolted, possibly welded to the lateral vertical uprights (welding makes disassembly less easy).

Pour mettre en place l'arbre d'enroulement, on l'emmanche sur l'un des bouts de l'arbre 14, puis, le réducteur du montant opposé étant dévissé, on recule ce réducteur en le poussant sur la plaque 12 pour faire reculer le bout d'arbre 14 dans le montant, de façon à pouvoir placer l'extrémité de l'arbre 7 en regard du bout d'arbre. Ensuite, par le fenêtre 21 prévue dans le montant 3, on pousse le réducteur pour engager le bout d'arbre dans l'extrémité de l'arbre d'enroulement 7, puis on visse ou on boulonne le réducteur par cette fenêtre.To set up the winding shaft, it is fitted to one of the ends of the shaft 14, then, the reducer of the opposite upright being unscrewed, this reducer is moved back by pushing it onto the plate 12 to make move the end of the shaft 14 back into the upright, so that the end of the shaft 7 can be placed opposite the end of the shaft. Then, through the window 21 provided in the upright 3, the reducer is pushed to engage the end of the shaft in the end of the winding shaft 7, then the reducer is screwed or bolted through this window.

Chaque montant peut en outre comporter des composants électriques de commande du moteur, des circuits de détecteurs de présence avec des commandes automatiques, etc. fixés dans le montant, ou sous la plaque de support du réducteur.Each upright may also include electrical components for controlling the motor, presence detector circuits with automatic controls, etc. fixed in the upright, or under the reducer support plate.

On voit que le transport et la mise en place de la porte sont considérablement simplifiés. On apporte sur le site les montants séparés, l'entretoise, l'arbre d'enroulement et le rideau roulé. L'assemblage consiste à ériger les deux montants et à les fixer. Les éléments mécaniques sont logés dans les montants. Il n'y a pas de traverse entre eux, seulement l'arbre et l'entretoise-capot. Le reste est simple et rapide.We see that the transport and the installation of the door are considerably simplified. The separate uprights, the spacer, the winding shaft and the rolled curtain are brought to the site. The assembly consists of erecting the two uprights and fixing them. The mechanical elements are housed in the uprights. There is no cross between them, only the shaft and the spacer-hood. The rest is simple and quick.
