Abstract:
A swinging-sliding door for vehicles, particularly for passenger vehicles, includes two door leaves positioned outside and within the wall of the vehicle in a closed state. For the door, a driving device for operating the door leaves includes pivotable, roller carrying levers which swing the door leaves from the closed position into a ready-to-open position; in addition, the driving device exerts a reaction force onto the pivotable roller carrying levers which, in closed position, results in locking them, a driving device includes a single electro-motor and gearing unit positioned laterally above the opening of the door, further having a case and a driving pulley, a traction belt is guided through a deflection pulley and couples the drive pulley to the door leaves via the roller carrying levers; the case has a flange carrying an eccentric control pin engaging a control lever fastened to a door post carrying the pivotable roller-carrying lever, and the control pin in a door closing position being held in a dead center position in a curved contour of the control lever so that the door is safely locked and can neither be opened manually nor by forces of the wind.
Abstract:
A power door operator for transit vehicles utilizing a rodless pneumatic cylinder as a prime mover in opening and closing doors in the sidewall of a transit vehicles. Door movement having a controlled, predetermined door edge force is achieved through mechanical coupling an external piston of the rodless cylinder and vehicle doors through an endless toothed belt. Magnetic coupling between internal and external pistons of the cylinder provide controlled force having a maximum or breakaway value applied to the operated door. A novel reaction lock operated by admission of pressurized air to the cylinder latches or unlatches the operated door in its closed position subsequent or prior to door closing or opening. Control of door motion at the ends of its travel is achieved through the use of a novel differential area internal piston in the pneumatic cylinder. Available internal piston force is modified for predetermined piston positions on approaching either end of the cylinder through the use of a sliding rod contained by the pressure sensitive internal position. Movement of the sliding rod adjust the effective piston area so as to modify available force to controlling door motion.
Abstract:
A device for moving at least one door leaf, includes a fixed beam that is fixed to the frame, a moving beam that is connected to the fixed beam by swinging rails which allow it to move transversely with respect to the axes of elongation of the fixed and moving beams, a motor which drives the leaf in a movement parallel to the axis of elongation of the moving beam and which, during the swinging of the leaf, also drives a drive cam which is provided with a slot in which there is engaged a pin that is fixed to the fixed beam, and a central roller which is connected to the moving beam and circulates in a groove in the fixed beam during the movement of the leaf.
Abstract:
A drive device for a sliding door or a pivot and slide door of a transportation vehicle including at least one runner mounter such that it can at least move linearly so as to move a door leaf attached to the latter. A motor is attached to the runner of to the transportation vehicle. A first transmission mechanism between the motor and the runner affects the longitudinal displacement of the runner. Between the motor and the first transmission mechanism at least two attachment options are provided which differ in the arrangement relationship of the first transmission mechanism and the motor.
Abstract:
A locking device for a sliding door or a swing and sliding door having a door leaf, the lock device comprising a drive train including at least one motor, a drive transmission and a drive spindle. The locking device also comprises a locking transmission and a torque dividing arrangement.
Abstract:
The invention relates to a system intended to enable the translational movement of sliding doors and to actuate the blocking of same, whereby blocking means (14) can be actuated in a sequential and synchronised manner at the end of the translational movement of the doors. The invention includes a sliding door (1) actuated by a drive pulley (12) in turn actuated by a power source (2) operationally connected to an input shaft (5) of a planetary gear train (4) including a planet carrier (10) configured to activate the means (14) for blocking the door (1) when the door is in the closed position, such that the activation of said blocking means (14) can be prevented when the door (1) is not in the closed position
Abstract:
The invention relates to a rotation path detection device for vehicles of public transportation having a drive device (20) for an entry/exit apparatus, which is mounted so it can be pivoted and/or displaced. Said apparatus has a drive unit (22), an electric drive motor (44), and a first reduction gear (26) and a second reduction gear (72), which is connected to the drive motor (44), having a sensor for ascertaining the position of the reduction gear.
Abstract:
A pivoting sliding door for vehicles, particularly rail vehicles or lift cabins. The pivoting sliding door includes a vehicle body, at least one door wing which, in a closed position is arranged within the vehicle body and which, in an opened position is arranged in front of and on an exterior side of the vehicle body. Further included is at least one driving device, at least two transverse guiding devices and at least one longitudinal guiding device to permit a transverse movement of the at least one door wing to and along the vehicle body. The at least one longitudinal guiding device is moved by the at least two transverse guiding devices, and the at least one door wing is locked by a pivoting part that engages in one of the at least two transverse guiding devices.
Abstract:
An engagement element is provided on the inside of the door leaf or of the door at a defined distance from the inside of the door. A spring-loaded locking hasp lies horizontally opposite the engagement element on the inside of the door frame. The locking hasp has a semicircular or claw-shaped recess and a laterally projecting locking section. A locking element is movably guided inside the door frame and connected to a vertically movable rod. During the closing movement of the door, the engagement element engages with the recess of the locking hasp, which swings with its locking section in the direction of the center of the door opening and assumes a position parallel to the door and is locked in this position by a movement of the locking element which is triggered in the vertical direction.
Abstract:
A door system having a sectional door (D) moveable between an open position and a closed position, a track system (T, T1) guiding movement of the sectional door, and an operator system (10) driving movement of the sectional door, said operator system including a motor assembly (42) having an adjustable housing (48) and capable of pivotal movement to a door locking position, said adjustable housing having a base section (70), an extendable section (72), and a latching mechanism (100) for maintaining the extendable section in a desired position and for permitting selective axially repositioning of the extendable section relative to the base section.
