Definitions
- the invention relates to a drive actuator of a blind with adjustable blades.
- the invention therefore finds application in the field of venetian blinds arranged inside or outside buildings for sun protection.
- a first winder can raise or lower the blades of the blind and a second winder or pulley has the function of orienting the blades, the orientation of the blades to adjust the brightness to the inside the room.
- the first winder acts on a lifting cord, attached to a load bar and the second winder acts on an orientation cord connected to the blades.
- the first and second winders are arranged in a common rocker, driven by an output shaft of a blind actuator. During a rotation of the output shaft, the two reels are rotated. When the blades are oriented in an extreme position, i.e. completely closed, the orientation cord begins to slide on the second reel.
- blinds comprising two motors each feeding a different drive shaft, namely a drive shaft dedicated to the unwinding of the blind and a drive shaft dedicated to the orientation of the blades.
- this type of awning would be very heavy and not very compact since it would include an additional motor and add space at the horizontal box. This would prevent adding components to the horizontal box and limit the addition of new features for the blind. It is these drawbacks that the invention intends to remedy more particularly by proposing an actuator that makes the blind more compact and more ergonomic.
- the invention relates to a drive actuator of a blind with steerable blades, this actuator comprising a housing inside which is arranged a motor driving a first output shaft which protrudes from either side of the housing , characterized in that the actuator further comprises a second output shaft whose axis of rotation is parallel and not coincident with that of the first output shaft and controlled coupling means for selectively transmitting a rotational movement of the output shaft.
- the invention it is possible to decouple the function related to the adjustment of the height of the blind and the function related to the orientation of its blades. Thus, it is possible to go down or up the blind blocking the orientation of the blades.
- the integration of decoupling means in the actuator makes the blind more compact and adaptable to any type of venetian blind. The installation itself is facilitated because all the electrically controllable elements are close to each other, in the housing of the actuator. They can be controlled by the same control unit.
- an actuator may incorporate one or more of the following features taken in any technically permissible combination:
- the actuator comprises an electronic control unit of the coupling means.
- the coupling means and the electronic unit are arranged inside a housing.
- the motor is a dual output motor, the two outputs together forming the first output shaft of the actuator.
- the motor rotates a shaft which transmits, through a first gear, a rotational movement to the output shaft of the actuator.
- the coupling means comprises a second gear and the second gear comprises an electromagnetically controlled clutch.
- the first gear comprises an electromagnetically controlled clutch for controlling the rotation of the first output shaft.
- the invention also relates to a blind comprising a horizontal box supporting at least two rockers and an actuator, the actuator being disposed between two rockers, and a set of steerable blades characterized in that the actuator is of the type defined above.
- a blind may incorporate one or more of the following features, taken in any technically permissible combination:
- the first output shaft is secured to a first drive shaft of the blind and the second output shaft is integral with a second drive shaft of the blind.
- the first drive shaft and the second drive shaft each drive at least one winder integrated in one of the shutters of the blind, these rockers being arranged on each side of the actuator.
- FIG. 1 is a perspective view of a blind according to the invention
- FIG. 2 is a diagram illustrating the operation of an actuator according to the invention belonging to the blind of Figure 1.
- FIG 1 a blind S according to the invention.
- the blind S comprises, in the upper part, a horizontal box 10, U-shaped section and which extends along a longitudinal axis X1 0. Below the horizontal box 10, are arranged, with a regular interval, several blades 14 only some of which are shown in Figure 1.
- a load bar 12 which can raise or lower the blind.
- the load bar 12 is connected, by means of cords 16 to one or more first winders located at the level of the horizontal box 10.
- the first winders are located inside two rockers 8 which are each disposed at one end of the horizontal box 10, these reels not being visible in the figures.
- the cords 16 pass through the blades 14 into orifices 014 and their lower end is fixed to the load bar 12.
- the blind S comprises two cords 18 which are attached to each of the blades 12 and which are each wrapped around a second winder also disposed inside one of the rockers 8.
- the cords 18 form indeed a buckle engaged with the second reel acting pulley.
- the second winder causes the cords 18 to move, thus making it possible to orient the blades to adjust the brightness in the room.
- the cord 18 slides on the pulley.
- the first and second winders are driven, at the rockers 8, respectively by drive shafts 4 and 6.
- the drive shafts 4 and 6 are arranged parallel to each other along the box 10, that is to say that an axis of rotation X4 of the first drive shaft 4 is parallel to an axis of rotation X6 of the second rotation shaft 6 and the axis X10, without being confused.
- Each rocker 8 is generally parallelepipedal cross section complementary to that of the horizontal box 1 0 and is traversed by two drive shafts 4 and 6. Between the two rockers 8 is disposed an actuator 2.
- the actuator 2 is generally parallelepipedal and has a cross section complementary to that of the horizontal box 10. This allows easy integration of the actuator 2 in the box 10.
- the actuator 2 comprises a housing 20, for example a sealed housing, from which a first output shaft 21 and a second output shaft 23 extend on a first lateral face 20a which is the face of the housing 20 to the left in Figure 2.
- the two output shafts 21 and 23 also out on a second side face 20b which is the face of the housing 20 opposite the face 20a and which is located on the right in Figure 2.
- the Output shafts 21 and 23 respectively have X21 and X23 axes of rotation, these axes of rotation X21 and X23 being parallel and not coincidental.
- the output shafts 21 and 23 are respectively guided relative to the housing 20 by means of guiding means such as bearings or sealed bearings, not shown in the figures.
- the output shafts 21 and 23 are able to drive in rotation, respectively the drive shafts 4 and 6.
- the axis X21 coincides with the axis X4 and the axis X23 coincides with the X6 axis.
- the output shafts 21 and 23 are respectively secured to the drive shafts 4 and 6 by fitting the output shafts 21 and 23 in the drive shafts 4 and 6.
- the drive shafts 4 and 6 each comprise a hollow outlet sleeve, the hollow portion of which is adapted to receive the end of the corresponding output shaft.
- the output shafts 21 and 23 extend, via the drive shafts 4 and 6, to the level of the two rockers 8.
- Inside the housing 20 is disposed an electric motor 22, knowing that it can also be a geared motor.
- the motor 22 comprises a single output shaft 220 whose axis of rotation X220 is parallel to that of the output shafts 21 and 23 and which extends towards the first lateral face 20a.
- the motor 22 rotates a first gear 240 in engagement with a second gear 242.
- the first gear 240 and the second gear 242 have external teeth complementary to each other and together form a first gear 24.
- the second gear 242 is, in turn, integral in rotation with the first output shaft 21.
- rotation of the motor 22 causes rotation of the first output shaft 21.
- first gear 262 On the same output shaft 21 and the side of the side face 20b, is disposed a first gear 262 rotatably connected to the first output shaft 21 and which cooperates with a second gear 260.
- the second gear 260 is connected to the second gear shaft.
- output 23 whose axis of rotation is parallel to and not coincident with that of the first output shaft 21.
- the first gear 262 has an external toothing complementary to that of the second gear 260. They thus form a set of a second gear 26.
- the second gear 26 differs from the first gear 24 in that it further comprises an electromagnetic clutch 264 which selectively connects the gear 260 to the shaft 23. As a result, the rotation of the second output shaft 23 is obtained. selectively, i.e. in an uncoupled configuration where the electromagnetic clutch 264 is not active, the output shaft 23 is not rotated by the rotation of the first output shaft 21 .
- the actuator 2 comprises an electronic control unit 28 for controlling the clutch 264 by means of an electrical signal S28.
- the electronic control unit 28 receives an order from the operator. This command is issued, for example, by means of a remote control, not shown, which transmits control signals in the form of radio waves to a receiver 27 comprising an antenna located in the actuator 2.
- the control unit 28 activates or not the electromagnetic clutch through signal S28.
- the second output shaft 23 is integral in rotation with a not shown notched crown and the second pinion 260 has, inside, complementary grooves of the teeth of this ring.
- the ring moves by magnetization axially inside the pinion 260.
- the complementarity of the teeth with the splines involves the rotation of the second output shaft 23.
- the gear 26 forms therefore coupling means controlled between the first output shaft 21 and the second output shaft 23 and these coupling means are directly integrated with the actuator 2 and driven by the user.
- the first output shaft 21 drives the first drive shaft 4 and makes it possible to raise or lower the blind S, while the second output shaft 23 is integral with the second drive shaft 6 and allows the blades to be oriented. 14, to adjust the brightness in the room.
- the orientation of the blades is simultaneously at the raising or lowering of the blind. Conversely, it is possible for the user to go down or up the blind S with a fixed orientation of the blades 14. To do this, it is necessary to disable the electromagnetic clutch 264. The gear 260 then rotates freely around the axis X23 without driving. The orientation of the blades 14 is not changed during the adjustment of the height of the blind. Thus, starting from a configuration where the blades 14 are open, the awning blades are not closed prior to the descent of the blind.
- the reels located at the drive shaft 6 comprise a sliding system that acts when the blades have arrived in a fully closed or fully open position. This sliding system therefore allows the drive shaft 6 to run freewheel.
- These sliding systems are for example of the same type as those described above, implementing a cord loop on a pulley type reel.
- the selective coupling between the up / down function of the blind and the blade orientation function thereof implies that an orientation movement of the blind blades is based on an upward or downward movement of the deck. However, these movements up or down the apron are not perceptible by a user and do not create discomfort.
- the use of a transmission means of the rotational movement of the first output shaft 21 to the second output shaft 23 by a gear also implies that the orientation of the blades 14 is in the direction related to the movement of the blind. Indeed, it is the direction of rotation of the first output shaft 21 which determines the direction of rotation of the second output shaft 23 and, consequently, the direction of the orientation. However, the orientation movements of the blades in both directions are possible.
- the function of return angle, allowing the duplication of the drive axes is integrated with the actuator 2, which makes it possible to overcome the use of specific rockers 8 and gives more flexibility as to the adaptation of the actuator 2 on any blind.
- the various functions, such as the reception of control commands, the control of the coupling means and the control of the motor, managed by the control unit are therefore also integrated into the actuator which simplifies their development and the installation of the actuator.
- the motor is a double output motor.
- the two output shafts of the motor then correspond to the first output shaft 21 of the actuator.
- the coupling means between the first output shaft 21 and the second output shaft 23 differs from a gear, while being controlled by the user.
- the drive shaft 4 and the first output shaft 21 are monobloc and the drive shaft 6 and the second output shaft 23 are in one piece.
