Definitions
- the invention relates to a device for operating a closure element moving at least approximately vertically, comprising a motor, a reduction gear, a drive shaft for the closure element and a transmission mechanism between the reduction gear and the drive shaft, this transmission mechanism authorizing the disengagement of the closing element when going down when a resistant force opposes its going down.
- Such a device is known in particular from patent application DE 36 08 988.
- the transmission mechanism is a unidirectional coupling of the freewheel type ensuring the drive of the closing element when climbing.
- This device is furthermore equipped with a manual control making it possible to drive the closing element, in particular to open a shutter in the event of an engine failure, for example during a cut in the electrical supply.
- This manual control comprises a transmission by screw and toothed wheel, that is to say a transmission having a significant reduction.
- Such manual control does not allow rapid opening of the closure element in an emergency.
- Devices of the same kind are also known in which a special breakdown control mechanism is provided. This command also does not allow rapid opening, the weight of the closing element inducing a reduction in the mechanism.
- the object of the invention is to produce, by simple means, a device for operating an electric motor closing element capable of being opened manually very quickly.
- the device according to the invention is characterized in that it comprises elastic means for compensating for the weight of the closure element and in that the transmission mechanism consists at least of a friction coupling.
- the device according to the invention does not include a brake, which makes it possible to avoid the brake release system.
- a one-way coupling can be combined with the friction coupling so that when going up, the drive of the drive shaft is ensured by the one-way coupling mechanism, while when going down, the drive is ensured by the friction coupling.
- the presence of a friction coupling makes it possible to have less precise compensation for the weight of the closure element.
- the drive is less sensitive to the variations induced by the aging of the installation, as well as to the wear of its components.
- the manual drive of the closure element can be done either by acting directly on this closure element, or, when possible, by acting directly on its drive shaft.
- Figure 1 is an axial sectional view of a drive device for a roller shutter.
- FIG. 2 is a sectional and half-section view along II-II of FIG. 3 of the transmission mechanism 6 of FIG. 1.
- Figure 3 is an axial half-section view, along III-III of Figure 2 of the transmission mechanism.
- FIG. 1 shows a roller shutter winding tube 1 mounted in a window frame 2.
- the roller shutter has not been shown.
- the winding tube 1 is supported by a bearing 3 itself supported by a geared motor 4 mounted inside the winding tube 1 and fixed to the doorway 2.
- the winding tube 1 is rotatably mounted on a disc 5 fixed in rotation in the opening 2.
- the gear motor 4 drives the winding tube via a transmission device 6.
- the winding tube 1 is also integral in rotation with 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 shutter during its unwinding.
- the transmission device 6 is shown in Figures 2 and 3. It comprises a crown 9 integral in rotation with the winding tube 1 and having internally two opposite notches 10 and a disc 11 integral in rotation with the output shaft of the motor- reduction gear 4. This disc 11 is provided, in a manner known per se, with two pawls 12 mounted respectively on a spring 13 and cooperating with the notches 10 of the crown 9 to ensure the unidirectional drive of the winding tube 1 in the direction of the roller shutter winding.
- the transmission device 6 further comprises a friction coupling housed in the crown 9.
- This friction coupling consists of a pair of frustoconical 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 rotation with the crown 9.
- the winding When climbing, the winding is ensured by the one-way coupling. On the descent, if the roller shutter encounters an obstacle, the motor can continue to run without driving the winding tube 1 and the friction coupling slipping. In normal descent, the winding tube 1 is driven by the motor by the coupling to friction.
- the roller shutter can be rolled up manually by raising the roller shutter directly. This operation is easy due to the absence of a brake and the weight compensation of the roller shutter.
- the one-way coupling is eliminated.
- the friction coupling plays both up and down. Safety in the event of an uphill obstacle is also ensured, since in this case the friction coupling can slip as well as when descending.
- the device can be fitted with a lock activated manually or automatically when the shutter is closed so as to prevent opening by unauthorized persons and to ensure burglar-resistant security.
- the device according to the invention is applicable to all closure elements moving vertically or obliquely.
