Definitions

  • the present invention relates to a system for actuating a roller shutter and a sliding canvas in parallel.
  • mosquito net can be wound in the rolling shutter box on an axis parallel to the winding tube of the rolling shutter ( EP1300541 , DE20200860 , FR2717531 , FR2936006 ). When the net is manually operated, open the window to maneuver it.
  • the roller shutter and the mosquito net are driven by two motors integrated in the drive tube of the rolling shutter deck. This concept requires, in addition to two motors, two control points to select one or the other, which is expensive.
  • the web shaft and the shutter shaft are driven by a single motor.
  • This system is used to maneuver a canvas by keeping it tense.
  • This tension can be achieved by making sure to always pull the fabric by two drive axes selectively activated according to the direction of traction of the fabric ( US4690195 ).
  • This voltage can be achieved by rotating two axes simultaneously with a single motor. One is connected to the winding tube and the other on the final blade. The speeds being different, it creates a tension of a system of spring which tends the canvas ( US4976302 ).
  • one axis causes the winding of the shutter apron and the other the winding of the mosquito net.
  • a clutch or selector system activates the drive of one or the other. The differentiated selection of one of the drive axes requires a command from the user. It's not automatic.
  • JP H08232563 describes a system for actuating two elements sliding in parallel and driven respectively by winding tubes.
  • This system comprises a differential and two brakes for locking respectively one of the winding tubes to allow rotation of the other winding tube.
  • Such a system requires the control of the two brakes to selectively obtain the maneuvers of the two elements.
  • the invention intends to remedy by proposing a new system for actuating a roller shutter and a fabric, allowing roll-out and winding sequences of the roller shutter and the simpler fabric. and less expensive.
  • the actuating system is characterized in that it comprises a brake exerting a resistant but non-locking torque against the rotation of the winding tube of the fabric so that the differential selectively and automatically transmits the rotational torque of the actuator to the winding tube of the flap via the first outlet when the winding tube of the flap is not blocked, or to the winding tube of the fabric via the second outlet when the winding tube of the flap is blocked.
  • the unwinding and winding of the shutter and the fabric are successive and automatic by acting on the outputs of the differential.
  • the figure 1 represents an actuating system S of a shutter 2 and a fabric 4, the shutter 2 and the fabric 4 sliding in parallel.
  • the fabric 4 may be in particular a mosquito net.
  • the actuator 6 may be an electric motor. It can also be a manual actuator, such as a crank.
  • the actuator 6, the shutter tube 8 and the fabric tube 10 are mounted between two cheeks 14 which delimit a boot of the shutter 2.
  • the shutter 2 and the fabric 4 slide parallel in two lateral guides 16.
  • the system S comprises a differential 12 detailed kinematically on the figure 2 .
  • the differential 12 has an inlet 120 formed by a sun gear driven in rotation by the actuator 6.
  • the inlet 120 is engaged with the output shaft 60.
  • the differential 12 comprises a first outlet 122 formed by a carrier wheel. Satellite rotating the shutter tube 8, and a second output 124 formed by a sun gear rotating the canvas tube 10.
  • the output 122 carries a satellite wheel 126 in engagement with the input 120 and the output 124.
  • the Differential 12 selectively transmits the rotational torque of the actuator 6 to the shutter tube 8 or to the fabric tube 10.
  • the satellite wheel 126 has an axis of rotation X126 parallel to the axis X8, according to the principle of the epicyclic gear.
  • the differential 12 may comprise more than one satellite wheel 126, and the satellite wheel or wheels 126 could be arranged along an axis perpendicular to the axis X8 as can be seen on FIG. figure 11 described below.
  • the actuator 6 and the differential 12 are integrated in the shutter tube 8.
  • the shaft 60 of the actuator 6 can be engaged with the sun wheel 124, while the tube of cloth 10 is driven by the sun gear 120.
  • the fabric tube 10 can be driven by the planet carrier wheel 122.
  • the tube 8 of the flap is rotated by the sun gear 120.
  • this structure can be reversed, the actuator 6 driving the planet wheel 122, while the flap tube 10 is driven by the sun wheel 124.
  • the differential 12 drives the canvas tube 10 when the shutter tube 8 is blocked.
  • the shutter tube 8 can be blocked by the arrival of the shutter 2 in an end position.
  • the system S may comprise a device 18 for controllably blocking the flap tube 8 or the outlet 122, making it possible to obtain the maneuvering of the fabric 4 outside the end-of-travel positions of the flap 2.
  • the differential 12 rotates the fabric tube 10 in one direction or the other via a transmission train.
  • the device 18 may be for example an element mounted between the shutter tube 8 and a fixed part 180 of the system S, and for braking the shutter tube 8.
  • the system S includes a brake 20 exerting a torque resistant against the rotation of the output 124.
  • the resistive torque on the output 124 is greater than the resistive torque on the output 122, and the rotation is transmitted to the output 122 and therefore to the tube of component 8
  • the resisting torque exerted by the brake 20 does not cause a complete blocking of the outlet 124.
  • the resistive torque on the outlet 122 becomes greater than the resistive torque on the output 124.
  • the torque exerted by the actuator 6 via the differential 12 on the output 124 becomes greater than the resisting torque exerted by the brake 20, and the differential 12 therefore causes the outlet 124 and therefore the fabric tube 10.
  • This arrangement allows automatic sequential actuation of the shutter 2 and the fabric 4, obtained by the sole control of the actuator 6 by an interface not shown.
  • the system S operates as follows, when the shutter tube 8 is blocked by the arrival of the shutter 2 in an end position. In an initial configuration represented in figure 6 , the shutter 2 and the fabric 4 are wound up.
  • the actuator 6 is turned on, driving the shutter tube 8 according to the arrow F1, and the shutter 2 descends according to the arrow F2.
  • the actuator 6 retains the fall of the shutter 2 via the differential 12 to a low end position of the shutter 2, shown in FIG. figure 7 .
  • the brake 20 holds the canvas tube 10 stationary.
  • the low end position can be obtained for example by a stop 34.
  • the stop 34 may for example be provided on the guide elements 16 or directly on a window or door sill.
  • the shutter tube 8 can no longer rotate and thus the torque provided by the actuator 6 increases.
  • the actuator 6 drives the fabric tube 10 according to the arrow F3 through the differential 12 to lower the fabric 4 along the arrow F4 to a low end position, represented at figure 8 .
  • the fabric 4 is immobilized against the abutment 34.
  • the actuator 6 draws the flap 2 via the differential 12 according to the arrow F6 to a top end position of the flap 2, shown in FIG. figure 9 .
  • the brake 20 maintains the Canvas tube 10 still.
  • the upper limit position of the flap 2 can be obtained by a stop 36.
  • the stop 36 can be for example provided on the guide elements 16.
  • the flap tube 8 can no longer rotate and therefore the torque provided by the actuator 6 increases.
  • the actuator 6 causes the tube 10 rotating in the arrow F7 through the differential system 12 to go up the fabric 4, according to the arrow F8, to a position high end of the canvas 4, which corresponds to the initial configuration of the figure 6 .
  • the descent and the ascent of the fabric 4 are thus obtained automatically and using a single actuator 6, depending on the arrivals of the flap 2 at its low and high end position.
  • the user does not have to operate a command to obtain the maneuver of the canvas 4.
  • the controllable blocking device 18 may specify a blocking of the flap 2 at a particular position at any time.
  • the actuation of the fabric 4 can be made in the direction of the descent or the rise.
  • the mechanical structure of the elements of the system S is detailed at figure 3 .
  • the actuator 6 is mounted in the shutter tube 8.

  • the differentially differentially differentiated 12 is the shutter tube 8 via a drive wheel 26, or an axis 28 extending through guide elements 30 to the toothed wheel 124a which drives the tube 10 through the gear train 22.
  • the output 122 of the differential 12 has fluted shapes 122a which cooperate with fluted shapes 260 provided on an inner side of the drive wheel 26.
