Definitions

  • the spring break or of other springy devices, might be a static and / or dynamic potential danger.
  • the spring is used in other to give an extra torque to the winding shaft permitting the use of a cheaper electric motor.
  • the extra elastic torque, given at the spring during the installation, is transferred little by little while the rolling shutter rise up. If the spring break itself , the whole closing system begins unstable and potentially dangerous.
  • FIG.1 represents a well known and used system, called shaft with balancing spring ; the rolling shutter goes up and down wrapping itself over the octagonal tube, that is tightly fixed at a rotating gear.
  • FIG 2 and 3 show the conceived system before the powerful torsion spring is loaded.

  • One extreme of the strong torsion spring, 2, is fixed at the square mechanical shaft.1 (under 3B); the other extreme of the spring is fixed at the octagonal tube (in 3A). This tube may rotate on bearings around the axis of mechanical shaft , 1.
  • rotating gear is tightly fixed at the rotating octagonal tube head, 3B, , that means it may rotate in regard to the square mechanical shaft, 1.
  • blocking gear may axially slide along the square mechanical tube, 1. That means it can not rotate in regard to the shaft even if it may rotate some degrees together with it.

  • the higher torque of powerful torsion spring, 2, will win the small opposite torque of little torque spring, 7, and the friction strength will keep the small metal plate, 9, in the position over the stops, 11 , keeping both gears , 4 and 5, aloof, permitting the normal up and down movement of rolling shutter. This precariuos position, however stable, will keep till the powerful torsion spring, 2, will not break.

Abstract

La présente invention a été développée pour être utilisée avec un volet roulant domestique ou industriel. Grâce à la présente invention, il est possible d'arrêter la chute d'un volet roulant lorsque le ressort d'asservissement, situé au niveau du moteur ou du mécanisme manuel, se brise. Dans la réalité, le dispositif est composé d'un arbre mécanique carré qui peut tourner de quelques degrés par rapport à un tube rotatif octogonal, grâce à un dispositif mécanique, de deux ressorts de torsion, l'un ayant un couple élevé et l'autre ayant un couple opposé faible, de deux engrenages, l'un rotatif, l'autre fixe, qui peuvent s'accoupler, d'un ressort de compression, et de quelques autres pièces de raccordement mécanique. Pendant le fonctionnement normal, le couple de ressort élevé dépasse le couple opposé faible, obligeant le dispositif à adopter une position précaire, mais stable. Dans cette position, les engrenages sont éloignés les uns des autres, et le tube octogonal peut tourner, afin d'enrouler ou de dérouler le volet roulant. Lorsque le ressort d'asservissement, qui possède le couple le plus élevé, se brise, le dispositif est obligé de se déplacer immédiatement vers une position plus stable dans laquelle l'engrenage rotatif est solidement accouplé avec l'engrenage fixe. Cette position arrête toute rotation de l'engrenage rotatif et, ainsi, la chute du volet.
