Abstract:
A sliding door operating mechanism for a vehicle to provide access to the vehicle through an opening in a wall thereof, includes at least one sliding door and reciprocating power means and transmission means for transmitting movement of the power means to the door for performing opening, closing and locking movements thereof. A beam structure carries the door, the power means and the transmission means. The beam structure extends across and is accommodated with an upper portion of the opening so as to be slidingly movably driven by the power means between a relatively retracted position within the opening, in which the door is located in a first plane in a closed position confined within the opening, and a relatively less retracted position, in which the door is located in a second plane exteriorly of the opening allowing movement of the door means along the second plane.
Abstract:
A method of aligning a door operating system for operating an upwardly acting door including an operator that directly interrelates with a counterbalance assembly in the door operating system to move the door, where the operator is at least partially supported on the counterbalance assembly, loosely attaching the operator to a header adjacent the door, and, moving the door from a closed position to an open position and returning the door to the closed position to achieve alignment. Once aligned, the operator is securely attached to the header to maintain the system's alignment.
Abstract:
Drive system for moving a load along a curved path. The drive system includes a base for mounting the drive system, the base having a curved track for guiding the load along the curved path. There is a load engaging mechanism mounted on the base for movement relative to the base, the load engaging mechanism being for moving the load. The load engaging mechanism has a curved track engaging roller for engaging the curved track. A linear drive mechanism including a linearly driven member is mounted on the base. The linearly driven member includes a driving pivot. A drive link is attached to the driving pivot at a drive force receiving end of the drive link, the drive link including a driven pivot at a drive force communicating end of the drive link. The driven pivot is attached to the load engaging mechanism, whereby linear motion of the driving pivot causes motion of the load along the curved path.
Abstract:
The invention relates to a motorised locking device for a door (2) intended in particular for a rail vehicle, with at least one leaf (3); the said device comprising: a tilting-body motor (9), intended to be mounted on the vehicle, the axis (10) of the said motor being substantially parallel to the longitudinal direction of movement of the said leaf (3), an output (11) of the said motor being connected to means for the longitudinal transmission of movement to the leaf, the body (13) of the said motor being arranged to be driven in conjoint rotation by the output (11) or immobilised in rotation with respect to the latter, means (8) of locking the leaf in the closed or open position comprising at least one locking finger (18, 18a) for locking in position and a substantially longitudinal ramp (19), the said finger (18) and the ramp (19) being fixed respectively to the tilting body and to the leaf, characterised in that the body (13) of the said motor (9) has at its end directed towards the leaf in the closed position a fixed arm (21) extending in a direction substantially parallel to the axis (10) of the motor on the side of the said leaf in the closed position, at least one locking finger (18, 18a) being fixed to the free end of the said arm (21), so that the said locking finger (18, 18a) is fixed at a distance from the end (20) of the motor body and the bulk of the device is reduced.
Abstract:
A tension apparatus of a vehicle door powered sliding device comprises a motor fixed to a base plate, a wire drum mounted to the base plate by a first shaft and rotated by the motor, a wire cable provided between a vehicle sliding door and the wire drum for pulling the sliding door forward or rearward when the wire drum rotates, first and second tension arms rotatably mounted on the first shaft and having tension rollers which makes contact with the wire cable, an intermediate lever rotatably mounted on the first shaft, an adjusting member for fixing the first tension arm and the intermediate lever so that an angle of the first tension arm and the intermediate lever can be adjusted, a tension spring provided between the intermediate lever and the second tension arm.
Abstract:
A device for moving a swinging and sliding door in a mass-transit car, especially a car that travels along a track. Each panel of the door slides lengthwise along a guide element. The guide element moves as part of a four-point articulation across the plane of the panel. The lengthwise motion of the leaf is coordinated with its transverse motion by a rail. The rail is fastened to the doorframe. Guide means are fastened to the panel and engage the rail. A drive mechanism on the panel directs force toward the guide element. As the drive mechanism (20-22, 30 & 31, or 40 & 4n1) reacts it exerts torque on an expansion element (25, 35, or 45) between the guide element (3) and a supporting component (25.2, 35.2, or 45.2) attached to the doorframe (16). The torque produces a force substantially normal to the guide element. The force generates the transverse motion.
Abstract:
The door comprises at least one sliding leaf which is capable of engagement and disengagement transversely within the door-frame, two separate toothed racks being mounted on each leaf and each associated with a pinion supported by a guided carriage, the two pinions being coupled by means of a coordinating shaft. Operating means comprising a motor and a mechanism for driving the pinions are rigidly fixed to at least one of two crank-arms, each crank-arm being pivotally connected to a carriage and to the door-frame.
