Definitions

  • the invention relates to a set of motorized shutters to be fixed at the level of an opening in a building.
  • the solutions of the prior art define a synchronization of the movements of the two wings.
  • the shutters must be closed or opened according to a particular order, due to their asymmetry and the presence of a joint cover, that is to say a blade covering one leaf on the other.
  • the main sash including the cover slat or joint cover, must be driven first when opening and last when closing to ensure that the cover slat properly covers a so-called secondary sash.
  • a first motorization solution consists of using a one-piece motorization assembly, integrating the two motors for each leaf in the same box,
  • Another motorization solution consists of using independent motorization modules, each comprising a motor, assigned to the motorization of 'a fighter.
  • a first mechanical module comprising a first motor drives a first leaf

  • the module comprising the control unit is qualified as an electromechanical module.
  • These two modules are generally covered with a finishing cap.
  • Each module also comprises a mechanical transmission device, in particular a pinion transmission device, making it possible to transmit the movements provided by the motors respectively to the main and secondary leaves.
  • a transmission shaft is located at the output of these transmission devices. Arms connect the transmission shaft to the leaves to transmit the rotational movement of the corresponding motor into a movement of the leaf around its hinges.
  • Known motorization assemblies therefore comprise an electronic control unit, which controls the power supply to the motors and in particular has means of electronic monitoring, in particular means for detecting an abutment force (by measuring engine torque, torque variation or underspeed). These force detection means make it possible to stop the motor when the detected forces exceed a predetermined threshold. This prevents damage to the motor in the event of too great an effort.
  • the forces detected at the level of the electronic unit are consecutive to forces applied to at least one of the leaves, in particular due to an obstacle or a gust of wind when the shutter is in motion or in an intermediate position between the completely open position and the fully closed position of the sashes or attempted intrusion when the sash is closed.

  • the force detection means provided at the electronic control unit can make it possible to limit the forces, for example those provided by the motor if they are contrary to the forces exerted on the leaf. However, they cannot always protect the driveline. For example, in a particular case where a connection between the transmission shaft and the arm is in the form of a hexagonal connection, significant efforts can lead to a degradation of the hexagonal connection, at the level of an arm or at the level of a transmission shaft, resulting in significant play, or even slippage of one of the parts relative to the other in subsequent movements.

  • the arm is integral with the fuse body and the breakable part(s) and the transmission shaft comprises the reception zone and the zones for receiving the breakable parts of the mechanical fuse after rupture, or vice versa.

  • the fuse body comprises a central opening, in that the at least one breakable part is a leg connected to the fuse body, the leg extending from an edge of the central opening towards the center of the opening.
  • the at least one breakable part has a rounded free end.
  • the number of breakable parts is three, distributed regularly inside the opening of the fuse body.
  • the number of breakable parts is three, distributed unevenly inside the opening of the fuse body, while the number of reception areas is four.

  • the transmission shaft 70 comprises housings called reception areas 221, 222, 223, 224, for example in the form of grooves, corresponding at least to each breakable part 211, 212, 213, 214 of the mechanical fuse 200. These grooves 221, 222, 223, 224 are formed by milling in the solid end of the transmission shaft 70. Each reception area or groove 221, 222, 223, 224 is adapted to receive a breakable part 211, 212, 213 , 214 of the mechanical fuse 200 in a mounted configuration of the mechanical fuse 200 on the transmission shaft 70.
  • the mechanical fuse 200 can be assembled without clearance, or with a controlled clearance, with the transmission shaft 70, in inserting the breakable parts 211, 212, 213, 214 in the form of lugs in the corresponding grooves 221, 222, 223, 224 along a longitudinal axis of the transmission shaft.
  • the cooperation of the breakable parts 211, 212, 213, 214 and of the grooves 221, 222, 223, 224 ensures that the arm is driven in rotation by the transmission shaft in normal operation.
  • the motorization assembly 10, in particular the transmission shaft 70, also comprises one or more housings called reception zones 241, 242, 243, 244 of the breakable part or parts of the mechanical fuse 200 after rupture. These reception zones 241, 242, 243, 244 are located in the extension of the grooves 221, 222, 223, 224 accommodating the breakable parts 211, 212, 213, 214 or are at least partially coincident with the grooves of the drive shaft. transmission 70.
  • the motor assembly 10 thus comprises reception areas 221, 222, 223, 224 of the breakable parts 211, 212, 213, 214 of the mechanical fuse 200 and reception areas 241, 242, 243, 244 of these breakable parts after breaking, the reception zones being offset at least partially with respect to the reception zones 221, 222, 223, 224.
  • the length of the grooves 122 is greater than the length 121 of the breakable parts 211, 212, 213, 214, which makes them suitable for forming the reception zones 241, 242, 243, 244 of the breakable parts 211, 212, 213, 214 of mechanical fuse 200 after breaking.
  • the breakable part or parts of the fuse mechanically detach from the fuse body, move freely away from fuse body 202 and are housed in the reception area(s) 241, 242, 243, 244 provided for this purpose.
  • the disengagement of this or these breakable parts of the mechanical fuse 200 releases the rotation between the arm and the transmission shaft 70.
  • the arm thus rotates without load and no longer risks driving the motor or the transmission device and damaging them. .
  • the rounded free end of the breakable parts 211, 212, 213, 214 facilitates the sliding of the severed part in the groove after rupture and therefore a better evacuation of the severed part in the reception zone. This also limits the risk of the severed part jamming in the corresponding groove.
  • the angles can penetrate into the material constituting the transmission shaft and the breakable parts 211, 212, 213, 214 can get stuck across the shaft grooves: the movement between the transmission shaft and the arm is no longer free.
  • the dimensions of the breakable parts 211, 212, 213, 214 also affect the sliding from the reception area to the reception area.
  • the guiding of the breakable part once severed is all the easier as the length of the breakable part is large with respect to the width of the grooves.
  • the width of a breakable part is much smaller than that of the corresponding groove, which corresponds to the presence of a controlled clearance between the mechanical fuse 200 and the transmission shaft 70)
  • the length of the breakable part being close to the width of the groove, the breakable part will tend to break before touching a wall of the groove. It can easily be evacuated to the corresponding reception area.
  • the mechanical break zone 231, 232, 233, 234 is located outside of the circle C70 in which the transmission shaft 70 is circumscribed. Severing breakable parts 211, 212, 213, 214 under the action of a high mechanical force causes them to break, but the surface of the break zone is generally uneven and rough. It is therefore preferable for it to be located outside and away from the circle C70 in which the transmission shaft is circumscribed. This avoids damage to the transmission shaft during movements of the arm or the transmission shaft after the breakage.
  • the breakable parts 211, 212, 213, 214 are distributed regularly or not around the mechanical fuse 200, in particular inside the fuse body 202 and are connected to the fuse body by mechanical break zones 231, 232, 233 , 234 of smaller section, that is to say of smaller thickness or smaller width Izr. This reduced width can be obtained by molding or by laser cutting.
  • the section of the mechanical break zones 231, 232, 233, 234 is equal to the section of the breakable parts.
  • the breaking torque C2 for the mechanical fuse 200 in fact depends on the number of breakable parts, their positioning with respect to the fuse as well as the section of the breaking zone 231, 232, 233, 234.
  • the use of four grooves made by removing material from the solid end of the transmission shaft allows a very simple industrial manufacturing operation, by two orthogonal cutter passages.
  • the grooves 221, 222, 223, 224 extend along orthogonal diameters of the transmission shaft 70 and emerge on either side of the transmission shaft 70.
  • the breaking torque C2 can be adapted in particular by using only part of the grooves.
  • the embodiment thus comprises three breakable parts distributed unevenly inside the fuse body 202, while the number of grooves 221, 222, 223, 224 is four.
  • One of the grooves is therefore empty when the mechanical fuse 200 is mounted on the transmission shaft 70.
  • the three breakable parts could alternatively be regularly distributed at 120° from each other, however, the (Or zones for receiving the broken parts of the fuse) corresponding, also at 120° from each other, would then be more complex.
  • the zone for fixing the breakable parts 211, 212, 213, 214 to the fuse body 202 can be confused with the zone of mechanical rupture 231, 232, 233, 234.
  • the zone of mechanical rupture 231, 232, 233, 234 can be slightly offset towards the center of the fuse body 202, as long as the latter remains located outside the circle C70 in which the transmission shaft is circumscribed.
  • the fuse body 202 has an irregular inner periphery, comprising zones of release of material 204 at least on either side of the breakable parts 211, 212, 213, 214 fixed to the fuse body 202.
  • This release of material can be present including in the zone where the breakable part 214 should be located, omitted to adapt the breaking torque C2.
  • This release of material 204 allows a slight radial clearance for mounting the mechanical fuse 200 on the transmission shaft 70, this clearance making it possible to position a new replacement mechanical fuse 200 in the various possible angular positions and this even if there was a slight damage to the transmission shaft 70 (at the level of the supports of the 3 breakable parts severed during a previous movement).
  • the mechanical fuse 200 is integrally formed with the arm 9a, 9b.
  • the arm 9a, 9b In the event of over-exertion leading to the rupture of the mechanical fuse 200, only the arm 9a, 9b needs to be replaced: this is a simple and inexpensive mechanical part.
  • the integration of the mechanical fuse 200 in the arm 9a, 9b allows simplification of manufacture and assembly.
  • the material used for the arm 9a, 9b and therefore for the mechanical fuse 200 has interesting properties in terms of resistance and plastic behavior. It is indeed important that the mechanical fuse 200 has little or no plastic deformation before it breaks, so as to avoid introducing rotational play (due to plastic deformation) in the transmission chain.
  • the mechanical fuse 200 is an independent part, for example coupled to the arm 9a, 9b and to the transmission shaft so as to transmit the movement in normal operation between the two parts of the kinematic chain .
  • the mechanical fuse 200 needs to be replaced.
  • its design is more complex because it must incorporate coupling means, in particular means for coupling to the arm 9a, 9b.
  • the mechanical fuse 200 is made of high-strength steel (HLE S500 or S700), a material for which rupture occurs quickly after the onset of plastic deformation.
  • the material chosen for the transmission shaft is conversely the strongest possible: for example tempered and tempered steel.
  • the mechanical fuse 200 can be produced by molding and rectified by laser: the shape cut by laser, for example, makes it possible to refine the section or the width or the thickness of the zones of mechanical rupture 231, 232, 233, 234 and is produced so as to limit the heating by a passage of the laser beam in close areas and in a short period of time.
  • the figure 9 shows in dotted lines shrinkages of material 206a, 206b, reducing the section of the rupture zone 233.
  • This holding element can take the form of the fixing screw 72, screwed into a corresponding thread 73 provided in the transmission shaft 70 and of the washer 71.
  • a specific washer 71 is used.
  • the washer includes several stepped sections 71e, 71E.
  • a first section 71e in the center of the washer 71 has a lesser thickness than a second section 71e corresponding to its outer periphery.
  • the washer 71 must be mounted in such a way as to leave an axial play between its thinnest section and the fuse, in line with the breakable parts 211, 212, 213, 214.
  • the washer 71 is preferably symmetrical, that is to say say that it is layered on both sides. This makes it possible to simplify assembly insofar as no constraint on the direction of assembly of the washer must be imposed.
  • the sections of the mechanical break zones 231, 232, 233, 234 can all be identical. Alternatively, the sections of different rupture zones 231, 232, 233, 234 of the mechanical fuse 200 are different, the rupture torque C2 then being different for different breakable parts 211, 212, 213, 214. This makes it possible to favor parts of mechanical fuse 200 which will break before others. It is thus possible to control the order of rupture of the breakable parts 211, 212, 213, 214 of the mechanical fuse 200.
  • the various ruptures can be linked successively and quickly on the same event leading to a rupture. The stresses at the level of the transmission shaft 70 or of the motor MA, MB during the rupture event are thus gradually reduced. Alternatively, breaking a breakable part 211, 212, 213, 214 without breaking another reduces the breaking torque necessary to cut the remaining breakable parts. The motorization assembly is thus protected during successive rupture events.
  • a lintel being generally defined as an architectural element supporting materials of a wall above an opening in a building. It is in the same way applicable to the fixing of the frame elements in the lower position of the opening, that is to say at the level of a threshold of the opening.
  • the terms lintel and threshold both correspond to an architectural element of an opening.
