Definitions

  • the invention relates to a device for operating a closing element moving at least approximately vertically, comprising a motor, a reducer, a drive shaft of the element of closure and a transmission mechanism between the reducer and drive shaft, this mechanism transmission authorizing the disengagement of the element downhill closing when a resisting force opposes his descent.
  • Such a device is known in particular from the application for patent DE 36 08 988.
  • the transmission mechanism is one-way freewheel coupling ensuring the drive of the closure element in climb.
  • This device is further equipped with a manual control to drive the element of closing, in particular to open a roller shutter in engine failure, for example during a power outage of the power supply.
  • This manual control includes a screw and toothed wheel transmission, that is to say a transmission having a significant reduction.
  • Such an order manual does not allow rapid opening of the closing element in case of emergency.
  • the invention aims to achieve, by means simple, a device for operating an element of electric motor lock capable of being opened manually very quickly.
  • the device according to the invention is characterized in that that it includes elastic means for compensating the weight of the closing element and that the transmission mechanism at least consists of a friction coupling.
  • the device according to the invention does not include a brake, which allows avoid the brake release system.
  • a one-way coupling can be associated with the friction coupling so that when climbing, the drive of the drive shaft is provided by the one-way coupling mechanism, while that downhill, training is provided by friction coupling.
  • the manual drive of the closing element can be do either by acting directly on this element of closure, or, where possible, by acting directly on his training tree.
  • Figure 1 is an axial sectional view of a device rolling shutter drive.
  • Figure 2 is a sectional and half-sectional view along II-II of Figure 3 of the transmission mechanism 6 of Figure 1.
  • Figure 3 is an axial half-sectional view, along III-III of Figure 2 of the transmission mechanism.
  • Figure 1 shows a shutter winding tube 1 roller mounted in a window frame 2. The shutter was not shown. At its left end, the winding tube 1 is supported by a bearing 3 itself supported by a gear motor 4 mounted at inside the winding tube 1 and fixed to the doorway 2. At its other end, the tube winding 1 is rotatably mounted on a disc 5 fixed in rotation in the doorway 2. The gear motor 4 drives the winding tube through a transmission device 6.
  • the winding tube 1 is also integral in rotation of a disc 7 connected to the fixed disc 5 by a coil spring 8 working in torsion so as to compensate for the weight of the roller shutter when unfolding.
  • the transmission device 6 is shown in Figures 2 and 3. It includes a crown 9 integral in rotation of the winding tube 1 and having internally two opposite notches 10 and a disc 11 integral in rotation with the output shaft of the gear motor 4. This disc 11 is provided, in a known manner per se, of two pawls 12 mounted respectively on a spring 13 and cooperating with the notches 10 of the crown 9 to ensure unidirectional drive of the winding tube 1 in the winding direction roller shutter.
  • the transmission device 6 further comprises a friction coupling housed in the crown 9.
  • This friction coupling consists of a pair of tapered steel washers 14 and 15 compressed between the disc 11 and a threaded flange 16 screwed into the crown 9 so that it is integral in crown rotation 9.
  • the roller shutter can be rolled up manually by raising the flap directly rolling. This operation is easy due to the absence of a brake and compensation for the weight of the roller shutter.
  • the coupling unidirectional is deleted.
  • the friction coupling plays as well on the climb than downhill.
  • Safety in the event of an obstacle climb is also ensured, since in this case the friction coupling can slip as well as lowering.
  • the device can be fitted with an activated lock manually or automatically when the shutter roller is closed so as to prevent opening by unauthorized persons and to ensure the burglar-proof security.
  • the device according to the invention is applicable to all closing elements moving vertically or obliquely.
