Definitions

  • the present invention relates to improvements to a shutter crank rolling.
  • a crank has an arm central which is provided at each end with a point of articulation between, on the one hand a part connected to the connecting rod with the articulation of the axis winding of the roller shutter deck, and other part with a tubular part forming a means of gripping the crank.
  • cranks at the points articulation, are provided with an elastic member of the type spring, which depending on the direction of its mounting, brings or erases one of the parts of the crank by one position lying down in a folded position.
  • Some cranks are also without any indexing device or blocking, which does not allow to maintain in a position given the different components of the crank.
  • the weight of the various elements forming the crank naturally generates a stable position of balance which may not correspond to the wishes of the user.
  • the present invention therefore aims to overcome these disadvantages by proposing a crank system which stays in position whatever the configuration given by the user and which is independent of the mass of the various components.
  • the crank object of the invention comprising a central rod connected to each of its ends, by a point of articulation, to a first rod which is connected via a toggle of a gimbal to the axis of rotation of the roller shutter deck, and a second rod serving as a gripping means
  • the user is characterized in that at least one of the points of articulation has a section orifice polygonal line so as to cooperate with a bearing whose external profile is complementary to that of the orifice, said bearing comprising a central orifice oblong cross section which cooperates with an axis articulation with a plurality of facets so to connect said central rod respectively by means gripping and said first rod.
  • crank 1 object of the invention, it comprises a central rod 2 preferably made of a metallic material or a plastic with properties high mechanical.
  • This rod 2 is connected to each of its ends, by a point of articulation 3, 4, at a first rod 5 which is connected via a toggle joint of a gimbal to the axis of rotation of the roller shutter deck, and a second rod serving gripping means 6 to the user.
  • At least one of the points of articulation 3, 4 present at each end of said rod 2 has an orifice 7 of polygonal cross section (square, rectangular, hexagonal, octagonal ...) so as to cooperate with a bearing 8 whose external profile is complementary to that of port 7.
  • This bearing 8 force-fitted inside the orifice to polygonal cross section, is preferably made in a plastic material with an important elasticity module. It has a central opening 9 to oblong straight section which receives a hinge pin 10 with a plurality of facets 11.
  • the articulated axis 10 with facets 11 is made of a material with an index of higher hardness than that of bearing 8, so that allow elastic deformation of the internal surface orifice 9 oblong during the rotation of the axis hinge 10.
  • the number of facets 11 made on the axis hinge 10 determines the number of points indexing of the gripping means 6 and of the crank relative to the connecting rod 5 with the axis of rotation of the roller shutter deck.
  • Each of these positions actually corresponds to a configuration of the crank in the folded position (for work) or to a crank configuration in lying down position (for rest).
  • the central rod 2 is provided with a plurality orifices 13 uniformly distributed along its axis longitudinal, so as to allow the passage of a plurality of pins 14 coming from covers 15, preferably plastic and possibly colored, which fit together, in order to "dress" said central rod 2.
  • the articulation axes 10 are connected, on the one hand to the gripping means 6 and secondly to the rod 5 of connection, via a cup 16 and a sleeve 17.
  • the sleeve 17 intended to be connected to the link rod 5 to the axis of rotation of the roller shutter deck is shaped a tube obtained by a succession of operations of bar turning on a plastic profile or metallic, or by a material injection operation plastic, and has at each of its ends a perpendicular orifice 18, 19 to the longitudinal axis of the sleeve which respectively receives the hinge pin 10 with facets 11 and a connecting pin with the rod 5.
  • this rod 5 fits into the bore length of the sleeve and is held in position thanks to the pin.
  • the pin has a length at the more equal to the diameter of the sleeve 17 so as to allow free rotation of a cover 20 mounted on the sleeve 17.
  • this substantially comprises in its zone middle a groove 21 which receives an elastic washer 22 split which cooperates with a bloodletting performed at inside the bore of said cover 20.
  • the central rod 2 fits inside the sleeve 17 thanks to a groove 23 made at its end, forming thus a U.
  • the axis 10 with facets 11 which cooperates at the orifices 18 made radially in the zone 23 of the U has a length at most equal to the diameter of the sleeve 17 so as not to hinder the passage of a cup 16 which must cover the assembly.
  • the substantially tubular cup 16 masks, when is in position, the articulation point 3, 4 at the end of central rod 2. To this end, one of its ends forms a U and slides, at first, on the central rod 2 so as to allow the passage of the axis 10 of articulation inside orifice 9 of the bearing 8 and through the orifices 18 made at the end of the sleeve 17, and in a second step, the cup 16 is folded down so as to cover the end of the sleeve 17 and immobilize in translation the axis 10.
  • the sleeve 17 'intended to be connected to the gripping means 6 forming the end of the crank 1, is obtained by a plastic injection operation.
  • This sleeve 17 ' substantially cylindrical, has at one of its ends a U-shaped part 24, crossed radially by an orifice 25 for the passage of an axis 10 with facets 11 which allows the gripping means 6 to cooperate with each other end of central rod 2.
  • the sleeve 17 ' also has a plurality of grooves 26 allowing the attachment of a cover 27 turning acting as a handle itself.
  • this sleeve 17 ′ is covered by a cup 16 identical to that used to cover the sleeve 17 connected to the rod 5 for maneuvering the shutter deck rolling.
  • the rotating covers 20, 27 on which the user comes to position his hands when he activates the crank can be plastic and tinted in the mass of a color similar to the cover caps of the stem.
  • crank hoods, trim covers, sleeves, cups, ring, pins .
  • plastic in order to reduce the weight of the whole so as to guarantee that the crank is kept in position, especially in the work configuration, whatever the indexing position.
