Definitions

  • the present invention relates to an automatic operating device for a rolling shutter crank.
  • the invention finds applications in all areas of building closure and in particular in the areas of home renovation and improvement.
  • roller shutters are generally operated manually by a user by means of a rod connected to the hub around which the slatted apron is wound and a crank allowing the user to actuate the rotation of the rod and consequently of the hub.
  • These manual roller shutters are relatively tedious to unroll and roll up because many turns of the crank are required to unroll or roll up the entire slatted curtain.
  • certain rolling shutters comprise an electric motor housed in the hub and driving said hub in rotation.
  • the electric motor connected to the electrical network, allows automatic winding and/or unwinding of the slat apron around the hub.
  • the electric motor is controlled from a control switch or a remote control.
  • Such electric roller shutters are generally installed in new homes. Their installation in a home being renovated is relatively expensive because it requires not only the removal of the manual roller shutter and the installation of the electric roller shutter, but also the installation of the electrical wiring allowing the motor to be powered from the electrical network.
  • the applicant proposes a device for motorizing the crank of a rolling shutter, this device being removable so as to be able to be used successively on several shutter cranks rolling.
  • crank refers to all the articulated elements, mounted at the end of the rod 250 (end opposite the hub) used to drive the hub of the roller shutter in rotation.
  • This crank comprises three elements 210, 212, 214, connected by two joints 220, 222 which allow either a position at rest in which the three elements are aligned, or a positioning in operation in which the central element 212 is perpendicular to the other two elements 210, 214.
  • the end element of the crank that is to say the element furthest from the hub, constitutes the handle 210 of the crank 200.
  • the automatic maneuvering device 100 is mounted around the handle 210, for example near the hinge 220. In other embodiments, the automatic maneuvering device 100 can be mounted around any of the other two elements. 212, 214 of the crank 200, close or not to a joint 220, 222.
  • the automatic maneuvering device 100 is shown in a general perspective view on the figure 2 and according to sectional views on the figures 3 and 4 .
  • This automatic maneuvering device 100 comprises a first gear element 120 and a second gear element 130, meshed one inside the other.
  • the first gear element 120 and the second gear element 130 each comprise a toothed crown, that is to say a crown or ring whose outer wall is provided with several teeth forming a set of teeth.
  • An example of first gear element 120 is shown in the figure 8 which comprises an outer wall 121, an inner wall 122 delimiting an orifice 124 and a toothing 123.
  • the second gear element 130 is substantially identical to the first gear element 120, only the internal dimensions of the crown varying with respect to those of the first gear element 120.
  • the toothing 133 of the second gear element 130 and the toothing 123 of the first gear element are of complementary shapes and dimensions so that they mesh with each other and transmit one to the other a circular motion.
  • the first gear element 120 is designed to be mounted around one element of the crank 200.
  • the second gear element 130 is designed to be mounted around an electric motor 140.
  • the electric motor 140 which is connected to a power supply unit 160, drives the second gear element 130 in rotation; the second gear element 130 drives the first gear element 120 in rotation, via the interlocking teeth 123 and 133; the first gear element 120 in turn drives the crank 200 in rotation.
  • the first gear element 120 is mounted around the handle 210 of the crank 200, this handle 210 being aligned with the other elements 212, 214 of the crank 200 and secured with these other elements 212, 214 via the joints 220 and 222.
  • the crank 200 being integrally mounted at the end of the rod 250, said rod 250 is also rotated, which causes the hub of the roller shutter to rotate.
  • the electric motor 140 is a direct current motor such as, for example, a DC motor or a brushless motor (without commutator) whose torque and power are between 40Nm and 90Nm, the brushless motor having the advantage of being effective over a long life.
  • the electric motor 140 is powered by a power supply unit 160.
  • the power supply unit 160 comprises an electrical connection device or wiring for connecting the electric motor 140 to the electrical network, for example via a wall socket.
  • the power supply unit 160 comprises an electric battery, for example rechargeable, which provides the electric current necessary for the operation of the electric motor 140.
  • the electric motor 140 is connected to a control unit 170 designed to control the starting and/or stopping of the electric motor 140.
  • This control unit 170 can, for example, be connected between the power supply unit electric 160 and the electric motor 140.
  • This control unit 170 comprises, in certain embodiments, a remote control electronic card.
  • This electronic card can be connected by a wireless link, for example an infrared link or a Bluetooth link, to a remote control by which the user controls the closing or opening of the roller shutter.
  • the electronic card includes a voice recognition module allowing the user to control, by voice, the closing or opening of the roller shutter.
  • the electronic card is connected by a wireless link, for example a Bluetooth link or a link by a mobile telephone network, to an application downloaded into a mobile telephone or a tablet; the user can then control the opening or closing of the roller shutter from his mobile phone or tablet.
  • This variant has the additional advantage of allowing control of the opening/closing of the roller shutter from outside the home, once the connection between the electronic card and the mobile phone or tablet is established.
  • the automatic maneuvering device 100 comprises a casing 110 in which are housed all the parts of said automatic maneuvering device described above.
  • the first and second gear elements 120, 130 are housed in the housing 110; similarly, the electric motor 140, the electric power unit 160 and the control unit 170 are also housed in the housing 110.
  • the housing 110 not only houses all the parts of the automatic maneuvering device, but it protects them also dust, humidity and shocks.
  • This box 110 can be made of any material suitable for receiving electrical components. It can advantageously be made of a relatively elastic material, such as example the elastomer, so as to absorb the shocks if the automatic maneuvering device moves during its operation.
  • the box 110 is equipped with a removable fixing element (not visible in the figures), such as for example one or more suction cups, making it possible to fix the automatic maneuvering device against a support, such as a neighboring wall, during its operation.
  • a removable fixing element such as for example one or more suction cups
  • the automatic maneuvering device 100 as described above has the advantage of being easy to install since it is simply mounted on the crank 200.
  • the user simply needs to fit the crank 200, for example the handle 210 of the crank, inside the first gear element 120 and to power the device 100 - either by connecting the power supply unit 160 to a wall socket, or by installing a previously charged electric battery - for the automatic maneuvering device to be operational.
  • the automatic maneuvering device 100 can be uninstalled just as easily by carrying out the reverse operations of those of the installation. Given this ease of installation and uninstallation, the automatic maneuvering device 100 is removable and easily moved from one roller shutter to another, in particular when all of its parts are housed in the box 110. A single automatic operating device 100 can therefore be used for all the roller shutters in the home, which is particularly economical for the user.
  • the automatic maneuvering device 100 comprises a locking system 150 making it possible to lock the positioning of said device 100 around the crank 200.
  • a locking system 150 is represented on the figures 5, 6 And 7 .
  • the locking system 150 comprises a positioning rail 151 and a locking abutment 153.
  • the positioning rail 151 comprises two parallel pads 151a, 151b, spaced apart by a width approximately equivalent to the width of the joint 220 around which the automatic maneuvering device is positioned; these two runners 151a, 151b are designed to fit at least partially into the articulation 220.
  • the positioning rail 151 can comprise one or more lateral orifices 152, each intended to receive a guide head 155.
  • each guide head 155 is fixed on the upper surface 126 of the first gear element 120 and two side holes 152 are made in the positioning rail 151, each guide head 155 being housed in one of the side holes 152.
  • each of the side orifices 152 is of longitudinal shape and is made in one of the pads 151a, 151b of the positioning rail 151, so that each of the pads 151a, 151b can be guided along the guide head 155 during longitudinal displacement.
  • the locking abutment 153 is housed in a central orifice 156.
  • This central orifice 156 is formed in the junction zone of the two pads 151a, 151b.
  • the locking abutment 153 can be mounted on a spring 154, itself housed at least partially in an orifice 125 made on the surface of the toothing 123 of the first gear element 120.
  • the spring 154 forms, with the locking abutment 153, a retainer serving to lock the positioning rail around the articulation 220 of the crank.
  • the spring 154 and the locking abutment 153 are pushed into the first gear element 120; when the positioning rail 151 is positioned around the articulation 220, the spring 154 is decompressed and the locking abutment 153 maintains the positioning rail 151 in the position where it fits the articulation 220.
  • a positioning rail threshold 151 has been described.
  • the locking system 150 can comprise two positioning rails positioned head to tail, on either side of the articulation 220, as shown in the figure 5 .
  • the locking system 150 as just described is only one embodiment. Other embodiments of the locking system can be provided such as, for example, a pin surrounding the joint and closed by a hook. Whatever the embodiment, the locking system 150 has the effect of blocking the automatic maneuvering device 100 on the crank 200 and of blocking the joint 220 so that the crank 200 remains in the so-called rest position. during operation of the electric motor and therefore during unwinding or rolling up of the slatted curtain.
  • the locking system 150 is then mounted on the outer surface of the housing 110 so as to be easily accessible by the user, the spring 154 then being housed at least partially in an orifice of the housing 110.
  • the automatic operating device according to the invention comprises various variants, modifications and improvements which will appear obvious to those skilled in the art, it being understood that these variations, modifications and improvements are within the scope of the invention.
