Abstract:
The invention relates to a mechanism (1) comprising a shaft (3) and an element (8) provided with teeth (89) for co-operating with a catch (6) which oscillates during rotational movements of said shaft (3), for driving a closure means (T) of an opening (O). The inventive mechanism is also provided with a safety system comprising braking means (20) or means for blocking the catch (6) in its oscillatory movement, said braking or blocking means being controlled by means (8, 9, 30) for detecting the state of a spring (10) used to compensate the torque exerted on the shaft (3) by the closing means which can be an apron (T).
Abstract:
An actuation assembly (INST) of a screen (SCR) for closure, solar protection or privacy, comprising, on the one hand, a motorized actuator (ACT) furnished with wireless control command receiving means (RCU) and, on the other hand, a standalone power supply assembly (PWU) furnished with at least one rechargeable accumulator (BAT) and with a power supply connector (PR), designed to be connected to the motorized actuator (ACT) via an electric connection line (LIN) for the latter to be supplied with power by the energy of the accumulator (BAT), wherein the power supply assembly (PWU) comprises a man-machine interface (MMI) whose activation allows the transmission of information to the actuator, this information relating to the control of the wireless control command receiving means (RCU) of the actuator (ACT).
Abstract:
The invention relates to a mechanism comprising at least one spring (3) for compensating the weight of a closing screen, said spring (3) being fixed, at one of its ends (32), to a ring (6) which is rotatably arranged around a shaft (4) having a circular cross-section. A stop spring (7) which is arranged around the shaft (4) ensures a one-way coupling between the ring (6) and the shaft (4), means (8) being provided for controlling the centripetal effort exerted on said shaft (4) by the stop spring (7).
Abstract:
A mechanism (1) comprising a driving element (4) for rotationally driving a winding shaft (2) for a closing or sun-protection installation of an opening (0) and at least one spring (5) for compensating a weight of the installation. The spring (5) is mounted around the driving element (4) and is jointly associated with a sub-unit (10), which can be at least partially introduced in a unitary manner inside the shaft (2). The spring (5) includes a first end (51) kinematically linked to said driving element (4) so that the first end (51) is immobilized in rotation abut an axis of rotation (X-X′) of the shaft (2), and a second end (52) kinematically linked to the shaft (2) when the sub-unit (10) is placed inside the shaft (2) so that the second end (52) rotates about the axis of rotation (X-X′).

Abstract:
An operating device for a rolling shutter assembly comprising a reeling shaft for a shutter wherein the shaft is rotated by a motor connected to a flange. The flange is fixed to a toothed wheel that can mesh with a thread of a screw so as to immobilize the rotation of the flange. The thread of the screw is provided with at least one flat, so that the mechanical connection between the toothed wheel and the screw can be disengaged when a flat is positioned adjacent the toothed wheel. Disconnection of the screw from the wheel allows a rapid operation of the shutter for reasons of security or maintenance.
Abstract:
An electric gear motor with reduction gears and automatic brake for shutters, wherein an emergency control is provided to allow the shutter to be manually maneuvered in the event of motor brake down or loss of power. A toothed ring is normally retained in a non-rotatable position relative to the reduction gears under the influence of a yieldable leg of a spring pin. The yieldable leg is movable away from the ring to permit the ring to rotate with the reduction gears and free of a motor drive shaft in the event the motor fails to activate in a normal manner thus enabling the shutters to be manually operated.
Abstract:
Roller assemblies having a drum upon which a closure is wound and unwound and wherein a drive mechanism within the drum is meshed with a plurality of elongated ribs extending along the inner surface of the drum and wherein the limiting controls for the drive mechanism include a pair of travelling nuts which are also meshed with the ribs of the drum for mechanically actuating the limiting controls.
