The motorized drive according to the invention application is configured to open and/or close a wing of a barrier such as a door, main door, gate or swing shutter, a wall or sliding partition or other sliding wing. The motorized drive comprises includes a motor and a first reduction unit through which the motor can open or close the wing. The reduction unit comprises includes a first and a second toothed profile engaging together, thus realizing a gear with a variable transmission ratio depending on the angular and/or linear position of at least one of the two toothed profiles. At least one of the first and of the second toothed profile forms at least one toothed section having a pitch profile which is substantially non-circular or not formed by a simple arc of a circle or a straight line.

Motorized actuator and movable barrier provided with said actuator

The motorized drive according to the application is particularly suitable for auxiliary or emergency drives and is configured to open or close a wing of a barrier such as a door. The motorized drive includes a motor and a reduction unit through which the motor can open or close the wing, an auxiliary motor including a helical spring which is able to absorb mechanical energy during the opening of the wing and release it during the closing of the same, a reduction unit connecting the auxiliary motor to the wing. A first and a second toothed profile realize a gear with a variable transmission ratio. The first and/or the second toothed profile form at least one toothing having a pitch profile which is substantially non-circular or not formed by a simple arc of a circle or a straight line.

Motorized actuator and movable barrier provided with said actuator, particularly suitable for auxiliary or emergency drives

A bollard device including a frame insertable in a horizontal plane. A base plate is disposed on the frame and has a hole. A movable part is received within the hole and moves vertically between a retracted position, wherein an upper end thereof is flush with the base plate, and an extended position wherein the upper end of the movable part extends beyond the base plate to create an obstacle. The frame includes a plurality of metallic supports defining an underground housing for the movable part and guides by which the movable part slides vertically. Actuating element is housed either in the frame or in the movable part and is configured to permit the vertical movement of the movable part. The movable part includes a stem and a protective tubular member disposed on the stem and constrained thereon by removable coupling element permitting the protective tubular member to be removed.
