Abstract:
An actuating device (1) for a door (2) of a vehicle, particularly a bus, comprises: a support structure (5) comprising means (6) for connecting the device (1) to this vehicle, a door lifting unit (3) connected to the support structure (5) and which comprises a lifting member (4) movable between a lifted position and a lowered position and connectable to this door (2) such that this upward and downward movement results in a closing and opening movement of the door (2), blocking means (7) suitable to block this lifting member (4) in the lifted position, release means (8) suitable to release the blocking means (7) for allowing the lifting member (4) to be moved downward. This actuating device (1) comprises an auxiliary support device (9) distinct from the support structure (5) and removably connectable or connected thereto, wherein said blocking means (7) and said release means (8) are connected to this auxiliary support device (9).
Abstract:
A door system (1) comprises a door leaf (3) for closing off an entrance opening (4), a suspension rod (10) having two opposite ends (11, 12) supported by a support structure (13), a suspension member (14) that connects the door leaf (3) to the suspension rod (10) and that can slide together with the door leaf (3) along the suspension rod (10) from an initial position corresponding to a closed position of the door leaf (3), to a final position corresponding to an open position of the door leaf (3), wherein the two opposite ends (11, 12) of the suspension rod (10) are slidab!e in a horizontal direction transverse to the entrance opening (4) and the suspension member (14) is slidably coupled to and guided by a non-linear upper guide (17) positioned above the suspension rod (10).
Abstract:
A rotary actuator (1) for a door (2) or ramp comprises an electric motor (3), a reduction gear (4, 5) connected to a front portion (6) of a shaft (7) of the motor (3), an output shaft (8) connected to the reduction gear (4, 5), an automatic locking brake (9) connected to a rear portion (10) of the motor shaft (7) and a decoupler (11) connected between the rear portion (10) of the motor shaft (7) and the locking brake (9) and actuatable to decouple the motor shaft (7) from the locking brake (9).
