  • Device for operating a closure element moving at least approximately vertically
    Patent number: 5803150
    Abstract: The operating device comprises a drive shaft (1) driven by a geared motor unit (4) via a transmission mechanism allowing the closure element being lowered to be disengaged when a resistive force opposes the lowering thereof. The device has no brake. By contrast, it comprises a spring (8) for compensating for the weight of the closure element and the transmission mechanism (6) consists of a friction coupling and, possibly, of a one-way coupling mechanism.The absence of a brake and the weight compensation make it possible for the closure element to be raised easily and quickly by hand in an emergency, while the friction coupling allows the closure element to be driven downward by the motor.
