Description

L'invention se rattache au secteur technique des équipements motorisés comprenant un motoréducteur, notamment, dont on a besoin de connaître le nombre de tours.The invention relates to the technical sector of motorized equipment including a geared motor, in particular, which we need to know the number of turns.

L'invention trouve, par exemple, une application pour un ensemble de motorisation pour l'entraînement d'un volet roulant immergé dans un bassin de piscine.The invention finds, for example, an application for a motorization assembly for driving a rolling shutter immersed in a swimming pool.

Dans cet exemple d'application, comme il ressort de l'enseignement du brevet FR 3 017 892 , l'ensemble de motorisation est du type de ceux comportant au moins un groupe motoréducteur, comprenant un moteur électrique, un réducteur, un arbre de sortie fixe et un flasque apte à être monté à l'intérieur d'un rouleau, pour l'entraînement du volet roulant, en vue de l'ouverture ou de la fermeture dudit volet. Ledit ensemble comporte en outre un corps fixe recevant le moteur et le réducteur, ainsi que des moyens de détection de la position du corps fixe, par rapport au flasque entraîné en rotation, afin de déterminer le nombre de tours réalisés par le groupe motoréducteur et de gérer les fins de course du volet roulant.In this example of application, as shown by the teaching of the patent FR 3 017 892 , the motor assembly is of the type of those comprising at least one geared motor unit, comprising an electric motor, a gear, a fixed output shaft and a flange adapted to be mounted inside a roller, for the rolling shutter drive, with a view to opening or closing the shutter. Said assembly further comprises a fixed body receiving the motor and the gearbox, as well as means for detecting the position of the fixed body, with respect to the flange driven in rotation, in order to determine the number of turns made by the geared motor unit and of manage the end of the roller shutter.

Selon l'enseignement du brevet FR 3 017 892 , les moyens de détection de la position du corps fixe, sont constitués par un interrupteur présentant une tige montée sur un ressort et équipée en bout, d'une roulette qui vient en contact avec des têtes de vis fixées circulairement sur le flasque, en position de débordement afin d'obliger la roulette assujettie à la tige de l'interrupteur, à se rétracter à chaque passage de vis pour provoquer la fermeture ou l'ouverture d'un contact électrique. A chaque passage de la roulette sur une tête de vis, se produit un léger choc. De plus, l'ensemble de l'interrupteur, avec la tige à roulette, est relativement encombrant, et d'un coût élevé.According to the patent teaching FR 3 017 892 the means for detecting the position of the fixed body are constituted by a switch having a rod mounted on a spring and equipped at the end with a wheel which comes into contact with screw heads fixed circularly on the flange in position overflow in order to force the wheel secured to the switch rod, to retract each time screw passes to cause the closing or opening of an electrical contact. Each time the caster passes over a screw head, a slight shock occurs. In addition, the entire switch, with the roller rod, is relatively bulky, and a high cost.

A partir de cet état de la technique, le problème que se propose de résoudre l'invention est de simplifier, de manière significative, les moyens de détection de la position du corps fixe, avec pour objectif de diminuer les coûts, en simplifiant la fabrication et le montage, tout en améliorant le fonctionnement.
Pour résoudre un tel problème selon l'invention, les moyens de détection comprennent au moins un interrupteur solidaire du corps du motoréducteur et présentant un doigt apte à prendre appui sur une couronne présentant facialement et alternativement, à intervalles réguliers, une série de formes concaves et convexes continues et régulièrement alternées en créant une série de vagues aptes à provoquer un déplacement du doigt lors de la rotation du flasque.
L'invention trouve une application dans le cadre d'un motoréducteur immergé, mais également dans le cadre d'un motoréducteur hors sol, ou installé dans une fosse, et plus généralement dans tous les cas où il est nécessaire de connaître le nombre de tours effectués par un motoréducteur.
La couronne présente avantageusement, directement lors de sa fabrication, les formes en creux et en relief, ladite couronne pouvant être rapidement fixée par tous moyens connus et appropriés sur le flasque, de manière fixe ou amovible.
Suivant d'autres caractéristiques de l'invention,

  • la couronne avec les formes en creux et en relief est réalisée d'une manière monobloc, notamment en matière plastique.
  • la couronne présente deux zones concentriques, à savoir une zone circulaire externe présentant les formes en creux et en relief, et une zone circulaire interne présentant des agencements de fixation avec le flasque.
Dans une forme de réalisation,
  • le doigt que présente l'interrupteur comprend, un galet apte à coopérer en appui avec la couronne.
  • le doigt est assujetti à un moyen élastique apte à le maintenir en appui sur les formes en creux et en relief de la couronne.
  • le galet est monté libre en rotation.
  • le diamètre du galet est au plus égal à la distance séparant deux formes en creux ou en relief.
From this state of the art, the problem to be solved by the invention is to simplify, in a significant way, the detection means of the position of the fixed body, with the aim of reducing costs, simplifying manufacture and assembly, while improving operation.
To solve such a problem according to the invention, the detection means comprise at least one switch integral with the body of the geared motor and having a finger adapted to bear on a ring face and alternately, at regular intervals, a series of concave shapes and convex continuous and regularly alternating creating a series of waves capable of causing a movement of the finger during the rotation of the flange.
The invention finds application in the context of a submerged geared motor, but also in the context of an above ground gear motor, or installed in a pit, and more generally in all cases where it is necessary to know the number of turns performed by a geared motor.
The crown advantageously has, directly during its manufacture, the hollow and raised forms, said crown can be quickly fixed by any known and suitable means on the flange, fixed or removable manner.
According to other features of the invention,
  • the crown with the recessed and raised forms is made in a monobloc manner, in particular plastic.
  • the ring has two concentric zones, namely an outer circular zone having the hollow and raised shapes, and an inner circular zone having fastening arrangements with the flange.
In one embodiment,
  • the finger that presents the switch comprises a roller adapted to cooperate in support with the ring.
  • the finger is subject to an elastic means capable of maintaining it bears against the hollow and raised forms of the crown.
  • the roller is free to rotate.
  • the diameter of the roller is at most equal to the distance separating two hollow or raised shapes.

L'invention est exposée ci-après plus en détail à l'aide des figures des dessins annexés dans lesquels :

  • la figure 1 est une vue partielle en perspective de l'ensemble de motorisation selon les caractéristiques de l'invention,
  • la figure 2 est une vue en perspective de la couronne,
  • la figure 3 est une vue en plan de la couronne.
The invention is described below in more detail with reference to the figures of the accompanying drawings, in which:
  • the figure 1 is a partial perspective view of the motorization assembly according to the features of the invention,
  • the figure 2 is a perspective view of the crown,
  • the figure 3 is a plan view of the crown.

L'ensemble de motorisation comporte un groupe motoréducteur (1), avec un arbre de sortie fixe, traversant un flasque (2), monté, par exemple, à l'intérieur d'un rouleau sur lequel est enroulé un volet roulant, dans le cas d'une application à un volet roulant immergé dans un bassin de piscine . Le flasque (2) est donc monté avec capacité de rotation par rapport à l'arbre de sortie du motoréducteur porté par un corps fixe (3). L'ensemble comporte en outre, des moyens de détection de la position du flasque (2) par rapport au corps fixe (3), afin de déterminer le nombre de tours réalisés par le groupe motoréducteur, et gérer les fins de course du volet roulant.
Cet ensemble motoréducteur n'est pas décrit plus en détail, car parfaitement connu pour un homme du métier, comme il ressort par exemple, de l'enseignement du brevet précité FR 3 017 892 .The motor assembly comprises a geared motor unit (1), with a fixed output shaft, passing through a flange (2), mounted, for example, inside a roller on which is rolled a shutter, in the case of an application to a rolling shutter immersed in a swimming pool. The flange (2) is mounted with rotational capacity relative to the output shaft of the geared motor carried by a fixed body (3). The assembly further comprises means for detecting the position of the flange (2) relative to the fixed body (3), in order to determine the number of revolutions made by the geared motor unit, and to manage the limit switches of the shutter .
This geared motor assembly is not described in more detail because it is well known to a person skilled in the art, as is apparent, for example, from the teaching of the aforementioned patent. FR 3 017 892 .

Selon l'invention, les moyens de détection sont constitués par un interrupteur (4) solidaire du corps fixe (3) recevant le motoréducteur (1). Cet interrupteur (4) présente un doigt (5), apte à prendre appui sur une couronne (6), fixée, comme il sera indiqué dans la suite de la description, sur le flasque (2).
La couronne (6) présente, facialement et alternativement à intervalles réguliers, une série de formes en creux (6a) et en relief (6b), aptes à provoquer un déplacement du doigt (5) sous l'effet de l'entraînement du flasque (2) assujetti au motoréducteur.According to the invention, the detection means are constituted by a switch (4) integral with the fixed body (3) receiving the geared motor (1). This switch (4) has a finger (5), adapted to bear on a ring (6), fixed, as will be indicated in the following description on the flange (2).
The ring (6) presents, facially and alternately at regular intervals, a series of hollow (6a) and raised (6b) shapes, able to cause movement of the finger (5) under the effect of driving the flange (2) subject to the gearmotor.

Selon l'invention les formes en creux (6a) et en relief (6b) sont constituées par une série de formes concaves et convexes continues et régulièrement alternées pour créer une série de vagues. La couronne (6) est fixée facialement sur le flasque (2), en regard de l'interrupteur (4).
Dans la forme de réalisation illustrée, la couronne (6) présente deux zones concentriques (6c) et (6d), à savoir une zone circulaire externe (6c) présentant les formes en creux et en relief (6a) et (6b), et une zone circulaire interne (6d), présentant des agencements de fixation avec le flasque (2). Par exemple, la fixation de la couronne (6) sur le flasque (2) peut être réalisée au moyen de vis (7) engagées au travers de trous formés dans l'épaisseur de la zone circulaire interne (6d).
L'extrémité libre du doigt (5) reçoit à libre rotation un galet (8), apte à coopérer en appui avec les formes en creux et en relief (6a) et (6b) de la couronne (6). Ce doigt (5) est assujetti à un moyen élastique, ou est directement conformé pour présenter une élasticité, afin d'être maintenu constamment en appui sur les formes en creux et en relief de la couronne (6). Le diamètre du galet (8) est inférieur, et au plus plus égal à la distance séparant deux formes en creux ou un relief de la couronne (6).
Il en résulte que lors de l'entraînement en rotation du flasque (2) par le motoréducteur, correspondant, par exemple, à l'enroulage ou au déroulage d'un volet roulant, le galet (8) roule successivement sur les formes en creux (la) et en relief (1b) de la couronne (6), provoquant, d'une manière concomitante, un mouvement de déplacement du doigt (5) de l'interrupteur (4). Le déplacement du doigt (5) procure alternativement une ouverture, puis une fermeture de l'interrupteur (4) connecté à un circuit de traitement, de tous types connus et appropriés. Par exemple, ce circuit de traitement est positionné dans une armoire de commande externe, afin de déterminer le nombre de tours effectués par le flasque (2).According to the invention the recessed (6a) and raised (6b) forms are constituted by a series of concave and convex forms that are continuous and regularly alternated to create a series of waves. The crown (6) is fixed facially on the flange (2), opposite the switch (4).
In the illustrated embodiment, the ring (6) has two concentric zones (6c) and (6d), namely an outer circular zone (6c) having the hollow and raised shapes (6a) and (6b), and an inner circular area (6d) having fastening arrangements with the flange (2). For example, fixing the ring (6) on the flange (2) can be achieved by means of screws (7) engaged through holes formed in the thickness of the inner circular area (6d).
The free end of the finger (5) freely rotates a roller (8), able to cooperate in support with the recessed and raised forms (6a) and (6b) of the ring (6). This finger (5) is subject to an elastic means, or is directly shaped to have elasticity, so as to be kept constantly resting on the recessed and raised forms of the ring (6). The diameter of the roller (8) is less, and at most more equal to the distance between two recessed shapes or a relief of the crown (6).
As a result, when driving the flange (2) in rotation by the geared motor, corresponding, for example, to winding or unwinding a shutter rolling, the roller (8) rolls successively on the recessed shapes (la) and in relief (1b) of the ring (6), causing, concomitantly, a movement movement of the finger (5) of the switch (4). The movement of the finger (5) alternately provides an opening, then a closure of the switch (4) connected to a processing circuit, of all known and appropriate types. For example, this processing circuit is positioned in an external control cabinet, to determine the number of revolutions made by the flange (2).

Comme indiqué, le contact électrique est réalisé à chaque sommet de la vague. Autrement dit, à chaque passage sur une forme en relief (6b), le déplacement du galet (8) est effectué sans aucun choc. L'interrupteur (4) utilisé est un interrupteur de conception simplifiée, d'un coût très réduit.As indicated, the electrical contact is made at each vertex of the wave. In other words, each passage on a raised form (6b), the movement of the roller (8) is performed without any shock. The switch (4) used is a switch of simplified design, a very low cost.

On observe également, que le coût de fabrication de la couronne (6), qui peut être usinée dans la masse, est également réduit. Sa mise en place est, par ailleurs, particulièrement aisée. Il en est de même en ce qui concerne sa fixation, qui peut être réalisée par de simples vis, comme indiqué, ou par tous autres moyens connus et appropriés.It is also observed that the manufacturing cost of the ring (6), which can be machined in the mass, is also reduced. Its implementation is, moreover, particularly easy. It is the same with regard to its fixation, which can be achieved by simple screws, as indicated, or by any other known and appropriate means.
