Definitions

  • the present invention relates to venetian blinds and drive mechanisms therefor.
  • venetian blinds are formed with a headrail, usually of channel cross-section, in which is mounted an operating mechanism controlled by a longitudinally extending drive shaft.
  • This drive shaft may be used to raise and lower the slats of the blind and/or may be used to tilt the slats.
  • the drive shaft is itself driven usually via a gear box which may be controlled, for example, by a bead chain or by a rotatable wand.
  • a venetian blind including a head rail, a drive shaft for raising and lowering the slats of the blind, a drive gear mechanism for rotating said drive shaft, said drive gear mechanism comprising a housing, means to mount the housing on the exterior of a venetian blind head rail, the rear face of the housing being engageable with said head rail, a manually operable drive member mounted for rotation in said housing, a driven shaft extending rearwardly outwardly of said housing and an epicyclic gear train operatively connected between said drive member and said driven shaft and a direction changing gear train, such as a bevel gear train, connecting the driven shaft of the drive mechanism to the drive shaft of the venetian blind.
  • the epicyclic gear train can be made very compact and can give a substantial gear reduction to make operation of the blind easy.
  • the housing has formed internally thereof, the ring gear of an epicyclic gear train.
  • the planet carrier of the epicyclic gear train including a bearing for the drive member which may be in the form of a bead chain pulley.
  • the direction changing gear train such as the bevel gear train, can include a braking means for holding the blind in a raised position.
  • FIG. 1 there is illustrated therein one embodiment of venetian blind according to the present invention, including a headrail 10, a bottom rail 12 supported by lift cords 14 and a plurality of slats 16 supported by ladder means 18.
  • Conventional raising and tilting mechanisms 20 are provided for raising and lowering the bottom rail 12 and for lifting the slats 16; these mechanisms are shown provided with a cover 22 and are themselves rotated by a drive shaft 24.
  • Rotation of the drive shaft 24 is effected by a drive mechanism 26.
  • the drive shaft includes a central screwthreaded spindle 28 carrying end stops 30 and 32 and a translating nut element 34, the elements 28 to 34 being utilized to control the amount of raising and lowering of the blind in a manner with which the present invention is not concerned.
  • the drive mechanism indicated with the general reference numeral 26, includes a housing 36 having, adjacent its lower rear edge, a rearwardly extending finger 38 and adjacent its upper rear edge a rearwardly extending hook 40.
  • the hook 40 can be engaged over the bead 42 of the front flange 44 of the headrail 10 and the finger 38 can be secured by a self tapping screw 46 engaged in a hole in the web portion 48 of the headrail 10 to hold the housing 36 on the front of the headrail 10.
  • An inner surface of the housing 36 is formed with a ring gear 50 of an epicyclic gear train indicated by the general reference numeral 52.
  • This gear train includes a planet carrier 54 mounted for rotation on a stub shaft 56.
  • the planet carrier has three rotatably mounted planet gears 58 thereon, which mesh with the ring gear 50 and also mesh with a sun gear 60.
  • This sun gear itself is journalled on a driven shaft 62 integral with the planet carrier 54.
  • the sun gear is formed integrally with a bead chain pulley 64 carrying a manually operable bead chain 66, ( Figure 1).
  • the driven shaft 62 has a hexagonal end portion 68 engageable in a direction changing gear train 70 as seen in Figure 1.
  • Such a structure is very compact and provides an efficient gear reduction ratio, for example of 3 to 1, so that the blind can be operated in an easy manner.
