Definitions

  • the present invention relates to closing devices in which the same motor member rotates the deployment of the apron and the fine adjustment of the screening of the light passing through it. It is particularly suitable for the operation of shutters with adjustable slats or openwork slats, Venetian blinds with vertical displacement, and curtains with vertical slats and with adjustable displacement.
  • this drive member When this drive member is constituted by a crank maneuvered by hand by the user, the adjustment of the orientation is relatively easy. It is no longer the same when the rotary drive of the stool is operated with the aid of an electric geared motor, since speed intervenes and considerably impedes control. Indeed, if one chooses a sufficiently high drive speed to ensure in acceptable conditions of rapidity the displacement of the blades, the adjustment of the orientation of the latter becomes very sharp and practically impracticable, whereas if in the opposite direction we mean to facilitate this adjustment operation by lowering the speed of rotation of the winding drum, the slowness of the movements becomes difficult to bear.
  • the present invention intends to remedy this, by providing the closing devices of the type envisaged with a reducing mechanism capable of imparting, fully automatically, to the winding drum two different speeds to correspond to the maneuvers successively intended for the movement of the apron and the precise adjustment of the screening of the light.
  • the mechanism according to the invention is defined in claim 1. Interposed between the output member of the drive system and the apron winding drum, it comprises a planetary input pinion which cooperates with at least one satellite pinion carried by an output ring and cooperating with a ring gear whose angular immobilization is operated using a braking device actuated by the aforementioned ring on the occasion of each rotation of the aforementioned planetary pinion.
  • the satellite pinion behaves either as a rolling member of revolution introducing a reduction ratio in the drive of the ring, or as a member which is not driven by no rotational movement along its axis and which consequently transmits the movement in the 1/1 ratio.
  • the braking device comprises at least one spring, the turns of which are arranged between a fixed friction wall and a cylindrical surface of the ring gear, while its ends, folded over inside this ring, cooperate with a radial finger integral with the outlet ring.
  • the reduction mechanism is mounted inside a casing formed by the assembly of a cylindrical housing 1 closed by a transverse bottom 2. At its center, this bottom 2 is provided with a bearing 3 which supports a shaft 4, one end of which is profiled at 4 a to be driven by the output member of the geared motor (not shown) intended for driving in rotation the winding drum of the blind in question.
  • the shaft 4, forming an input member for the mechanism comprises a toothed portion 4b which cooperates, in the manner of a sun gear with planet gears 5, in the number of three in the embodiment taken into account.
  • Each satellite pinion 5 pivots freely on an axis 6 which is mounted in cantilever on a plate 7 which screws 8 fix against the front face of an outlet ring 9.
  • This ring 9 is engaged with reduced clearance inside the axial opening of a rotating sleeve 10, itself centered in the casing 1-2.
  • the wall of the aforementioned opening of the sleeve 9 has, in front of the ring 9, a toothing 10 a which meshes with the planet gears 5, the sleeve 9 thus being comparable to a toothed crown.
  • the mechanism is provided with a braking system which comprises a spring 11, the turns of which are arranged between a rear cylindrical surface 10b of the sleeve or crown 10 and an annular friction lining 12 glued or otherwise immobilized against the internal wall of the housing 1-2.
  • the rear part of the ring 9 comprises, in addition to an axial means 9 has pierced in 9 b to ensure the driving of the usual end-piece with hexagonal section of the blind drums, a radial finger 9 c whose longitudinal faces are hollowed out notches 9 d .
  • notches 9 d are intended to accommodate the folded ends 11 a of the spring 11, which ends penetrate by notches 10 c inside a chamber 10 d formed in the rear bearing surface 10 b of the sleeve 10.
  • This chamber 10 d has in section a semi-circular profile which thus defines a sector-shaped projection 10 e .
  • the diameter of the wire which forms the spring 11 is such that in the rest position, that is to say when said spring is not subjected to any force, it bears simultaneously against the lining 12 and against the bearing surface 10 b of the socket 10, so that the latter is immobilized angularly.
  • the finger 9 c comes to bear against an end 11 a which engages in the notch 9 d which faces it.
  • the finger 9 c pushes the end 11 a , which has the effect of tightening radially inwards the spring 11 including the turns, by compressing against the reach 10 b , release the sleeve or crown 10.
  • the latter is consequently driven in rotation by the finger 9 c (see fig. 5), so that the gear reduction stops immediately and the awning drum, driven at full speed , can ensure the winding or rapid unrolling of the links associated with the blades.
  • the user can again control the gear motor in one direction or the other to pro yield to the adjustment of the orientation of the blades.
  • the planet gears 5 intervene as a result of the angular immobilization of the sleeve 10, so that the drum is driven at very reduced speed, thereby allowing perfectly precise adjustment.
  • the reduction mechanism according to the invention is capable of being produced as well as an accessory device suitable for being interposed between a usual closing device and its drive geared motor, as well as as an assembly capable of being directly incorporated to a device specially established for this purpose.
