Definitions

  • the present invention relates to the blind carrier which is designed to drive a blind winding shaft using the rotating force of a motor and to move a blind in a vertical direction.
  • Conventional blind carrier using an electric motor used a planetary gear and a bevel gear, a spur gear.
  • a blind winding shaft would tend to be rotated reversibly because of the load of the blind and the blind move downwardly when the blind was lifted.
  • a motor shaft needed an apparatus for protecting a reverse rotation. Although the apparatus was existed, the apparatus is retired or exchanged because of the aging.
  • the conventional carrier had a problem that a structure was complex and the cost of production was high because of having the multistage planetary gears for high reduction gear ratio.
  • an object of the present invention is to provide a blind carrier having a sun gear and, the single-stage planetary gears, the first housing having the first internal gear, the second housing having the second internal gear.
  • reduction gear ratio as high as or higher than that of the multistage planetary gears although a single-stage planetary gear is used.
  • a blind carrier which is connected to the driving shaft of the motor and moves a blind in a vertical direction by driving a blind winding shaft, comprises: a sun gear mounted to the driving shaft of the motor; a single-stage planetary gears externally engaged with the sun gear; the first housing having the first internal gear which is internally engaged with one end part of the tooth width of each planetary gear of the planetary gears, and which has the central axis coinciding with that of the driving shaft,; the second housing having the second internal gear which is internally engaged with the other end part of the tooth width of each planetary gear of the planetary gears, and which has the central axis coinciding with that of the driving shaft; and a driven shaft extending from the second housing connected to the blind winding shaft.
  • the first housing is fixed at the case of the first housing equipped at or around a blind head for no rotation.
  • the number of the teeth of the first internal gear is different from that of the second internal gear.
  • a blind carrier comprising; each planetary gear of the planetary gears has a circular hole at the center to be fitted loosely in each protrusion bar; each protrusion bar is fitted tightly in each marginal hole of a rotating plate which has also a central hole; and the rotating plate is fitted loosely in protrusion shaft formed as one body in the inside of the second housing.
  • a blind carrier comprising; each planetary gear of said planetary gears has a circular hole at the center to be fitted loosely in each protrusion bar; the each protrusion bar is fitted tightly in each marginal hole of a rotating plate which has also a central hole; and the rotating plate is fitted loosely in protrusion shaft formed as one body in the inside of the second housing.
  • a blind carrier comprising; the first housing has a stopping hill inside thereof; the second housing is inserted into the inside of the first housing; the driven shaft is inserted into the central hole of a disk- shaped cover; and the disk- shaped is connected with the first housing by means of a connecting member.
  • the blind carrier in accordance with the present invention can be used in a curtain and a stage-curtain, a partition, a shutter and so on.
  • the title of the present invention can be called a curtain carrier and a stage-curtain, a partition carrier, a shutter carrier and so on.
  • the characteristic of the present invention is that the first housing is fixed and, the number of tooth of the first internal gear is different from its second internal gear and, one end and the other of tooth width of the planetary gears commonly connects with the sun gear and the first internal gear and, the second internal gear each other.
  • the first effect of the present invention is that the second housing and the driven shaft extending from the second housing rotate as the sun gear mounted to the driving shaft of the motor rotates, but the sun gear mounted to the driving shaft of the motor doesn't rotate as the driven shaft extending from the second housing rotates. This is because of the first housing being fixed.
  • the second effect of the present invention is that the deceleration is dependent on not only a velocity which the sun gear rotates in and a velocity which the planetary gears revolve around the sun gear, but also the difference of the number of tooth of the first and the second internal gear, so the reduction ration in the single-stage planetary gears larger than it in multistage planetary gears. Because one end of tooth width of the planetary gears commonly connects with the sun and the first internal gear and, the other of it commonly connects with the second internal gear and, the number of tooth of the first internal gear is different from it.

Abstract

L'invention concerne un support de store conçu pour entraîner un arbre d'enroulement de store au moyen de la force de rotation d'un moteur et pour déplacer un store dans le sens vertical. Dans le support de store, une roue solaire (30) est montée sur l'arbre de moteur (40), des satellites (50) étant extérieurement en prise avec cette roue solaire (30). Des première et seconde roues à denture intérieure (16, 72) respectivement d'un premier et d'un second logement (10, 70) sont en prise, de façon commune et extérieurement, avec les satellites (50). Un arbre (76) entraîné, qui part du second logement (70), est relié à l'arbre d'enroulement de store. Le premier logement (10) est fixé à un carter, et ainsi l'arbre de moteur (40) ne peut pas effectuer une rotation non désirée. En outre, le support de store peut présenter un rapport de réduction élevé désiré, cela en fonction du nombre de dents de la première et de la seconde roue à denture intérieure (16, 72).
