Abstract: An anti-fall transmission device for a handling door (1) having a flexible curtain (5) to be stacked or rolled about a drive shaft (4) during the movements thereof between an open and a closed position, includes a separate electric motor or gear motor (7) attached along a rotational axis which is offset and parallel to that of the drive shaft (4), as a protective anti-fall device (8) for connecting the motor or the gear motor (7) to the drive shaft (4) and for preventing the flexible apron (5) from accidentally falling.

Abstract: The electrical braking device according to the present invention includes a braking element (2) which is formed, on the one hand, by electric jaws (7) and at least one sliding block (8) mounted in the proximity of the brake disk (3) in such a way that the latter passes at least partially through the electric jaws (7) and sliding block (8), and, on the other hand, by means (4) for fastening the electric jaws (7) and the sliding block (8) to the fixed frame (6) while providing the jaws and block with degrees of freedom obtained by the combination of different connections of the “flat plane contact” (FC), “point contact” (PC) and “annular linear contact” (AC) types, in order to compensate for the misalignments and defects in the shape of the brake disk (3) when the latter is driven in rotation.

Abstract: The device for recovering, storing and retrieving electricity from the decelerations of an electromechanical system such as a flexible curtain of a handling door is made up of a management interface (IG) connected to a frequency inverter (VF) and to a control logic board (CC) controlling the opening and closing of the flexible curtain of a handling door, the management interface (IG) including at least two power capacitors (C1, C2) connected to the grid via a first parallel branch, then connected to the grid during use of the energy by a serial connection in order to make it possible to store the energy from the decelerations and to retrieve the energy either during the following acceleration during opening of the flexible curtain or, in case of failure, to ensure sufficient opening of the flexible curtain of the handling door.

Abstract: The contact-free detection device for detecting the position of a winding drum (2) for a handling door is made up of a cam or code wheel (3) secured to the winding drum (2), inductive sensors (4, 5) positioned near the cam or code wheel (3), and an electronic board (7) including at least one prevention and security module (12) receiving the pulses generated by the inductive sensors (4, 5) so as to ensure the security of the rotation command of the driving axis of the winding drum (2) of the handling door.

Abstract: A vertical modular mount for a handling door (1) includes an upper plate (18) connected to a horizontal frame (4) and more particularly to a side flange (19), a lower plate (20) connected to the ground, a central web (21) connecting the upper (18) and lower (20) plates together, a cloth (23) arranged around the upper (18) and lower (20) plates in order to define an envelope (24) on the entire height of the mount (2, 3), and a guiding device (15) defining a slide for the movement of the flexible screen (6), characterized in that each of the members (21, 23, 15) forming the mounts (2, 3) of the handling door (1) are arranged so as to impart a high resilience to the latter, i.e. a high resistance to shocks due to the elastic deformation of each of the members.

Abstract: The vertically-opening goods-handling door includes an elastic retaining device (10) which include retaining elements (11) which, on the one hand, allow the screen or the flexible curtain (12) to be kept in a movement path between an open position and a closed position and, on the other hand, in the event of an anomaly, allow the screen or the flexible curtain (12) to deform elastically without the risk of the screen or of the flexible curtain (12) becoming unhinged or ejected from the lateral uprights (13, 14) and to revert to its initial shape after the anomaly has disappeared.

Abstract: The invention relates to a device for detecting an obstacle and limiting the force from the primary edge or sill nosing (10) of a flexible apron or curtain (5) in a goods-handling door (1) when the latter comes into contact with an obstacle (14) as it is being closed. The inventive device comprises safety cells (21, 22) which are positioned and fixed close to each guiding device (8) such as to emit a beam F that is directed along a vertical axis outside of the guide (15) so that the beam is interrupted upon deformation of the flexible curtain or apron (5).

Abstract: The modular drum according to the present invention consists of a central tubular profile (7a) made of steel or of a composite having in cross section a square or rectangular profile forming the central part or core of the said drive drum (7) and a demountable flexible shell (7m) having an external profile (7d) in the form of a portion of a cylinder and a flat and rectilinear internal profile (7e) complementary to that of the tubular profile (7a) so that the said drive drum (7) has a cylindrical external profile that can be deformed elastically under external pressure.
