Definitions
- the invention relates to the control of blinds of the Venetian blind type with horizontal slats.
- a blind generally comprises a vertically deployable apron composed of horizontal slats supported by flexible ladders and terminated by a low inal horizontal bar whose position is determined by means of at least two cords or ribbons capable of being wrapped around a horizontal output mandrel from a box or high module transforming a rotational movement of a horizontal input mandrel into another movement of rotation of the horizontal output mandrel in a determined direction, as is well known in one art.
- each rung of this flexible ladder has a substantially horizontal strip which can be oriented relative to this relative horizontality in order to adjust the orientation and more or less obstruct an access to light.
- This type of blind therefore requires several separate commands, in particular for lifting or lowering of the final horizontal bar and for the orientation of the slats.
- the controls have been separated so that one chain ensures the raising or lowering of the horizontal final bar and another chain ensures the adjustment of the orientation of the slats.
- This type of control by chains generally has a drawback in that the chains easily become entangled with one another or twist on themselves.
- the invention is situated in this context and aims to greatly simplify the control of such a blind, in particular of such a blind of horizontal Venetian type. She finds applications for other types of blinds, however.
- the top module of the blind comprises a first epicyclic train and a second epicyclic train arranged in series, each train having a set of satellite gears with parallel axes and meshing a crown enclosing a planet carrier, rotating axes.
- the planet carrier of one of the trains receives one of the ends of these "axes, while the planet carrier of one other train 1 receives the other end of these axes.
- the rotation of the planet gears of the one of the trains is inverted with respect to that of the satellite gears of the other of the trains by mutual meshing, the satellite gears of the second rotary planet carrier being driven in rotation by the horizontal input mandrel, while the first planet carrier rotary is integral in rotation with the horizontal output mandrel.
- the blocking in rotation of one of the crowns thus determines the direction of rotation 'of the horizontal output mandrel.
- the blocking in rotation of one of the crowns is obtained by means of a carriage provided with two pairs of teeth and movable horizontally in translation, so as to block only one of the crowns, the other remaining free.
- the carriage is secured to a pair of dogs capable of blocking the crowns, in such a way that only one of these crowns is blocked and the other remains free.
- the horizontal input mandrel is controlled in rotation by traction of a drive cable, one end of which is wound at rest on a recalled drive coil and idle in rotation in a determined direction.
- the drive cable passes through a hollow shaft carrying an eccentric cam at its upper end and the other end of which engages, at rest, in a form provided on a handle for controlling the drive cable.
- Figure 1 shows in perspective and exploded view the top module of the blind control device according to one invention
- Figure 2 shows in perspective and exploded view the two epicyclic trains arranged in series in the top module of Figure 1
- Figures 3A and 3B schematically illustrate the means of changing the direction of the horizontal mandrel output from the top module of Figure 1
- Figure 4 schematically shows in longitudinal section the two epicyclic trains assembled from the top module
- Figures 5A and 5B schematically and partially illustrate a blind according to one invention respectively in the rest position and in the pull position.
- a blind generally comprises a vertically deployable apron composed of horizontal slats supported by flexible ladders and terminated by a low final horizontal bar whose position is determined by means of at least two cords or ribbons capable of being wrapped around a horizontal output mandrel (not shown in the Figures).
- a top module as shown in FIG. 1, comprises a device which transforms a rotational movement of a horizontal input mandrel 6 into another rotational movement of the horizontal output mandrel in a determined direction.
- This top module is constituted by a casing comprising a bottom 8 and a cover 10 enclosing the mechanism for transforming the rotational movement.
- This mechanism essentially comprises a first epicyclic train 12 in series with a second epicyclic train 14.
- Each epicyclic train 12, 14 comprises a planet carrier 16, 18, a set of satellite gears 20, 22, and a crown 24, 28.
- each set of satellite gears 20, 22 comprises three gears .
- the planet carrier of one of the trains receives one end of the axes of the satellite gears, while the planet carrier of the other of the trains receives the other end of these axes.
- the satellite gears of each set have a mutual meshing zone and, outside this zone, a toothing zone which meshes, of course, the teeth provided on the internal face of the corresponding crown 24, 28.
- the input mandrel 6 always rotates in the same direction and engages the set of centripetal satellite gears 22 of the second epicyclic train 14.
- the second planet carrier 18 drives the output mandrel around which the aforementioned cords or ribbons of the blind are wound.
- the second planet carrier 18 is capable of turning in one direction or the other, as will be seen.
- the horizontal input mandrel 6 has a constant determined direction of rotation, while the output mandrel must be able to turn in one direction and the other to ensure either the lowering or the raising of the deck of the awning.
- one of the rings 24, 28 must be locked in rotation.
- each pair of teeth 32, 34 of the carriage 30, in practice, is integral with a dog clutch 40, 42 capable of respectively blocking either the crown 24 or the crown 28, and in such a way that only one of the crowns is blocked and that the other remains free.
- each dog clutch 40, 42 and each ring 24, 28 have a correspondingly facing radial wall.
- An accessory spring means 9 acting axially on the dogs makes it possible to ensure the synchronization of the toothed radial walls opposite between a dog and the corresponding crown.
- the translation of the carriage 30 is ensured by an eccentric cam means 44 cooperating with an opening 46 provided in the carriage 30.
- An irreversible wheel means 50 for example spring, ball or rock, is disposed at the outlet of the mechanism to prevent the awning of the awning from falling between two manipulations.
- the blind apron is manipulated by means of a hollow shaft 52 carrying the eccentric cam 44 penetrating into the opening 46 of the movable carriage 30.
- a rotation of this shaft 52 by a quarter turn or a half turn therefore causes displacement of the carriage 30 and, consequently, the change of the locked crown and, therefore, the change of the direction of rotation of the horizontal mandrel of exit.
- a cable 62 (FIG. 5B), secured to a handle 60 passes inside the hollow shaft 52 to serve as a control means for the user.
- the upper end of the cable guided by a mad pulley 54 with a horizontal axis, is connected to a drive coil 56 which transforms the tensile force exerted on the cable 62 by the user, in a movement of rotation of the mandrel horizontal input 6 via a free wheel (not shown in the Figures).
- a spring means makes it possible to return the drive coil 56 to its angular position of rest.
- the handle 60 When the user exerts no traction on the cable 62, the handle 60, recalled by the drive pulley 56, abuts against the hollow shaft 52 which comes to engage in a shape 64 provided on the handle 60, so that, in this position, the handle 60 and the hollow shaft 52 are linked in rotation.
- the length of the end of the windable cable " on the pulley is of the order of 80 cm.
- the user when he has chosen that the curtain of the blind must go up or down by a simple rotation of the shaft 52 by means of the handle 60 which he holds in one hand, only exercise one or more successive pulls on the cable 62 passing through the shaft 05/028802
- the cable 6-2 is cleaned automatically by the drive coil 56 biased.
- a device for controlling a blind of the “monocommando” type very simple to use, inexpensive to make and, above all, very compact, compatible with 1, thus obtains it.
- use of a conventional tall box of sheet metal blind for example 25 x 25 millimeters in section.
- the originality of this mechanism consists essentially in allowing the user to maintain his grip on the traction member, whether he wants to raise or lower the blind, all the commands can therefore be carried out with one hand.
- the transition from deployment to folding of the awning apron is thus achieved by a simple rotation of the operating rod.
- the horizontal input and output mandrels were provided with a 12-tooth pinion, the two times three satellite gears 20, 22 each had 12 teeth and the crowns 24 , 28 had 36 teeth.
- two ratios are obtained different reduction: a reduction of 1/4 for the folding of the apron and a ratio of 1/2 for the deployment of the apron.
