Description
La présente addition concerne un dispositif de débrayage et de réglage instantané des fins de course d'un enrouleur automatique du type décrit dans le brevet principal et destiné en particulier mais non exclusivement aux fermetures à enroulement telles que volets, rouleaux, stores, rideaux métalliques etc. The present addition relates to a device for disengaging and instantaneous adjustment of the end positions of an automatic rewinder of the type described in the main patent and intended in particular but not exclusively for roll-up closures such as shutters, rollers, blinds, metal curtains, etc. .
Le problème qui est résolu par le dispositif selon le brevet principal est celui de l'arrêt automatique du mouvement du rouleau après un certain nombre de tours dans un sens ou dans l'autre, le mouvement du rouleau pouvant être par ailleurs interrompu par coupure de l'alimentation en une position quelconque. The problem which is solved by the device according to the main patent is that of the automatic stopping of the movement of the roller after a certain number of turns in one direction or the other, the movement of the roller can also be interrupted by cutting off power in any position.
Le dispositif objet du brevet principal avait pour but de permettre le débrayage à volonté des fins de course et le réglage instantané de celles-ci après la mise en place et les essais de fonctionnement de la fermeture. Ce dispositif donne pleinement satisfaction mais il peut cependant être utile de parfaire le réglage d'arrêt de la fermeture en position haute ou en position basse afin de rattraper des jeux éventuels résultant du fonctionnement même de la fermeture. The object of the main patent was to allow disengagement at will of the limit switches and instantaneous adjustment thereof after the establishment and the operating tests of the closure. This device gives full satisfaction but it may however be useful to perfect the stop stop adjustment in the high position or in the low position in order to make up for any play that results from the very operation of the closure.
Avec le dispositif objet du brevet principal, il est nécessaire dans ce cas de procéder à des réglages complémen- taires un peu délicats, ce qui constitue une servitude notable. With the device which is the subject of the main patent, it is necessary in this case to carry out somewhat delicate additional adjustments, which constitutes a significant easement.
La présente addition a pour objet un mécanisme de réglage qui permet d'ajuster exactement les fins de course de l'exte- rieur du dispositif enrouleur ou de procéder à un réglage progressif complet. The object of this addition is an adjustment mechanism which makes it possible to adjust the limit switches exactly from the outside of the take-up device or to carry out a complete progressive adjustment.
Selon la présente addition, le dispositif de débrayage et de réglage instantané des fins de course d'un enrouleur automatique du type décrit dans le brevet principal est caractérisé en ce que les tiges solidaires des butées agissant sur les contacts de mise en route et d'interruption présentent des cannelures, lesdites tiges étant solidaires d'un pignon pouvant être actionné par une vis de réglage. According to the present addition, the device for disengaging and instantaneous adjustment of the end positions of an automatic rewinder of the type described in the main patent is characterized in that the rods integral with the stops acting on the start-up and interrupt have grooves, said rods being integral with a pinion which can be actuated by an adjusting screw.
Ainsi, par simple rotation d'une vis, le déplacement d'une tige de contact peut être exactement ajusté à la course de la partie inférieure de la fermeture. Thus, by simply rotating a screw, the displacement of a contact rod can be exactly adjusted to the stroke of the lower part of the closure.
D'autres caractéristiques et avantages de l'addition apparaitront au cours de la description qui va suivre d'un mode de réalisation particulier, donné à titre d'exemple non limitatif, en regard des figures qui représentent
- la fig. l une coupe longitudinale d'un dispositif selon l'addition
- la fig. 2 une coupe transversale selon la ligne Il-Il de la fig. 1
On a représenté sur la figure 1 l'extrémité gauche d'un dispositif d'enroulement d'une fermeture, les groupes motoréducteurs d'entraînement placés à droite du dispositif n'apparaissant pas.Other characteristics and advantages of the addition will appear during the following description of a particular embodiment, given by way of nonlimiting example, with reference to the figures which represent
- fig. l a longitudinal section of a device according to the addition
- fig. 2 a cross section along the line Il-Il of FIG. 1
FIG. 1 shows the left end of a device for winding a closure, the geared motor drive units placed to the right of the device do not appear.
Sur les figures, les éléments communs au brevet principal et à l'addition portent les mêmes références. In the figures, the elements common to the main patent and to the addition bear the same references.
Lorsque le tube d'enroulement 1 tourne sous l'action des motoréducteurs pour faire monter ou descendre la fermeture enroulée, il entrain avec lui une couronne 3 à denture intérieure qui est solidaire du tube. Cette couronne entraîne habituellement deux pignons 5 et 7 respectivement solidaires de deux vis 9 et 11 dont l'une a un filet à droite et l'autre un filet à gauche de manière à ce que l'une contrôle le sens de la descente et l'autre le sens de la pontée de la fermeture enroulée sur le tube 1. Deux écrous 13 et 15 sont montés sur les vis 9 et il et se déplacent dans des sens mutuellement opposés lorsque le rouleau 1 est anime d'un mouvement de rotation.Les écrous 13 et 15 ont une forme générale périphérique munie de dents susceptibles d'engrêner avec les cannelures des tiges 203 et 203 Au cours du fonctionnement normal, les tiges cannelées 203 et 203a empèchent les écrous 13 et 15 de se déplacer en rotation de sorte que le mouvement de rotation des vis 9 et 11 est transformé en un mouvement de rotation des écrous 13 et 15, écrous qui, en fin de course, viennent au contact des butées 21 et 23 respectivement ce qui déplace axialement lesdites butées et ferme l'un des contacts du contacteur 27. When the winding tube 1 rotates under the action of the geared motors to raise or lower the wound closure, it drives with it a crown 3 with internal toothing which is integral with the tube. This crown usually drives two pinions 5 and 7 respectively secured to two screws 9 and 11, one of which has a thread on the right and the other a thread on the left so that one controls the direction of descent and l 'the other the direction of the bridging of the closure wound on the tube 1. Two nuts 13 and 15 are mounted on the screws 9 and it and move in mutually opposite directions when the roller 1 is rotated. The nuts 13 and 15 have a generally peripheral shape provided with teeth capable of meshing with the grooves of the rods 203 and 203 During normal operation, the grooved rods 203 and 203a prevent the nuts 13 and 15 from moving in rotation so that the rotational movement of the screws 9 and 11 is transformed into a rotational movement of the nuts 13 and 15, nuts which, at the end of the race, come into contact with the stops 21 and 23 respectively which displaces said stops axially and closes the one of the contact's contacts ur 27.
Selon la présente addition, la vis 200 solidaire d'un axe porte un pignon coopérant avec le pignon 201 solidaire de l'extrémité de l'axe 202 lui-même solidaire de la tige cannelée 203. Le pignon 7 étant en position embrayée comme représentée sur B figure 1, l'action sur la vis 200 provoque, par l'intermédiaire du pignon 201., la rotation de la tige cannelée 203, ce qui provoque la rotation de l'écrou 15. L'écrou 15 se déplace donc à ce moment le long de la vis et peut être positionné en un endroit quelconque de manière à faire varier la course de déplacement. According to the present addition, the screw 200 secured to an axis carries a pinion cooperating with the pinion 201 secured to the end of the axis 202 itself secured to the grooved rod 203. The pinion 7 being in the engaged position as shown in B FIG. 1, the action on the screw 200 causes, via the pinion 201., the rotation of the grooved rod 203, which causes the rotation of the nut 15. The nut 15 therefore moves to this moment along the screw and can be positioned in any place so as to vary the displacement stroke.
Pour effectuer ce réglage, il est préférable que le pignon 7 soit en position embrayée dans la mesure où le mécanisme objet du brevet principal permet de réaliser l'indexation de l'interruption du courant par le nombre de tours du rouleau 1. To make this adjustment, it is preferable for the pinion 7 to be in the engaged position since the mechanism which is the subject of the main patent makes it possible to index the interruption of the current by the number of revolutions of the roller 1.
Lors du réglage par la vis 200, l'écrou 15 tourne autour de la vis 11 et celle-ci reste immobile. When adjusting with the screw 200, the nut 15 rotates around the screw 11 and the latter remains stationary.
L'action d'un tournevis sur la vis 200 provoque la rotation de celle-ci et, par suite, la rotation de la tige cannelée 203. Les dents de l'ecrou 15 engrènent avec les cannelures de la tige 203, ce qui provoque la rotation de l'écrou 15 qui ainsi se visse ou se dévisse sur la vis 11, ce qui provoque sa translation. A l'extrémité de chacune des tiges cannelées, les pignons de retour d'angle (201 pour la tige 203) sont irréversibles de sorte que les tiges 203 et 203a ne peuvent tourner que sous l'action des vis, ce qui assure normalement un mode de fonctionnement analogue à celui du brevet principal dans lequel les écrous 13 et 15 sont bloqués en rotation. The action of a screwdriver on the screw 200 causes the rotation of the latter and, consequently, the rotation of the grooved rod 203. The teeth of the nut 15 mesh with the grooves of the rod 203, which causes the rotation of the nut 15 which is thus screwed or unscrewed on the screw 11, which causes its translation. At the end of each of the grooved rods, the angle return pinions (201 for the rod 203) are irreversible so that the rods 203 and 203a can only rotate under the action of the screws, which normally ensures a operating mode similar to that of the main patent in which the nuts 13 and 15 are locked in rotation.
A la partie supérieure de la figure, la vis 204 agit sur le renvoi d'angle 205-206 et transmet le mouvement par l'axe 206a à la tige cannelée 203a. In the upper part of the figure, the screw 204 acts on the bevel gear 205-206 and transmits the movement by the axis 206a to the grooved rod 203a.
Si l'on agissait sur la vis 205 alors que le pignon 5 est débrayé comme représenté dans le haut de la figure 5, il serait nécessaire de prendre en considération le déplacement axial du pignon 5 pour effectuer un réglage correct. If one acted on the screw 205 while the pinion 5 is disengaged as shown at the top of FIG. 5, it would be necessary to take into account the axial displacement of the pinion 5 to effect a correct adjustment.
Il va de soi que des modifications peuvent être apportées au mode de réalisation qui vient d'être décrit, notamment par substitution de moyens techniques équivalents, sans sortir pour celà du cadre de la présente addition. It goes without saying that modifications can be made to the embodiment which has just been described, in particular by substitution of equivalent technical means, without departing from the scope of this addition.
