Definitions

  • This invention relates to an articulated sliding door assembly for a public transportation vehicle such as a railway vehicle.
  • Articulated sliding doors for rail vehicles are known in a variety of embodiments, which have in common the fact that they can be moved out of the closed position by a transverse or swinging movement into a position which is ready for opening, and subsequently moved parallel to the outer wall of the vehicle into a position which clears the door opening, as illustrated e.g. in EP 0 312 450 .
  • Such movement involves complex and bulky guiding and driving systems.
  • an articulated sliding door assembly for closing a doorway, comprising:
  • the guide rail assembly is particularly simple and robust, and does not require a complex and bulky linkage.
  • the articulated sliding door assembly further comprises driving means for moving the door leaf between the first end position and the second end position, which may advantageously comprise a stationary part that is fixed relative to the guide rail assembly.
  • the driving means can include a rotation motor having its stator fixed relative to the guide rail assembly and its rotor coupled to the door leaf via a transmission mechanism such as e.g. an endless belt transmission, a worm gear or a rack and pinion system.
  • a transmission mechanism such as e.g. an endless belt transmission, a worm gear or a rack and pinion system.
  • the driving means includes a linear motor, with one or more flat stators (i.e. stationary electromagnetic circuits generating a controlled magnetic field) fixed relative to the guide rail assembly and one or more rows of permanent magnets fixed relative to the door leaf, each of the rows extending horizontally substantially from one vertical edge of the door to the other and consisting of adjacent poles of alternate polarities.
  • the resulting assembly is particularly compact. This arrangement is particularly robust since it does not involve any transmission mechanism between the driving means and the door leaf.
  • the permanent magnets can be individual permanent magnets.
  • the row or rows of permanent magnets can be located at an upper and/or a lower horizontal edge of the door leaf, e.g. close to a guide rail of the guide rail assembly. According to a preferred embodiment, however, the one or more rows of permanent magnets are each located at an intermediate position below an upper horizontal edge of the door leaf and above a lower horizontal edge of the door leaf, preferably at a distance of the guide rails of the guide rail assembly, such that the guide rail assembly can be kept simple and compact.
  • the stators are located at the same height as the associated rows of permanent magnets, such that they do not necessitate additional space at the level of the upper guide rail assembly. Access to the stators is particularly easy for maintenance purposes.
  • the overall concept is particularly reliable since the upper rail assembly is independent and separated from the driving means.
  • the one or more stators face and overlap an end of the rows of permanent magnets close to a first vertical edge of the door leaf, so as to generate an electromagnetic force in the first position.
  • the rows of permanent magnets progressively move past the associated stators with a constant air gap.
  • the stators face and overlap a second end of the rows of permanent magnets, close to a second vertical edge of the door leaf.
  • the one or more rows of permanent magnets include at least two rows of permanent magnets and each of the two rows of permanent magnets consists of adjacent poles of alternate polarities, distributed such that when the stator associated with one of the two rows faces one of the poles, the stator associated with the other of the two rows faces a space between two adjacent poles.
  • the linkage may further comprise a coordination linkage for coordinating a translation motion of the door leaf with respect to the guide rail assembly and a motion of the guide rail with respect to the doorway.
  • an independent driving means may be provided to move the guide rail assembly between the recessed and protruding position.
  • a return means may also be provided to return or bias the guide rail assembly towards the recessed position.
  • the return means can be a spring or an electromagnetic device.
  • the guide rail assembly preferably comprises an upper guide rail assembly for guiding an upper edge of the door leaf.
  • the upper guide rail assembly may consist, as is well known in the art, of a rail provided with one or more raceways on which rollers attached to the door leaf can roll.
  • the door leaf can be at least partially or preferably fully suspended from one or more carriages rolling on one or more raceways of the upper guide rail assembly.
  • the articulated sliding door assembly further comprises a lower guide rail assembly for guiding the lower edge of the door leaf.
  • the one or more rows of permanent magnets are preferably each located above the lower guide rail assembly, such that the lower guide rail assembly can be kept simple and compact.
  • the door leaf is preferably at least partially and preferably fully supported on rollers rolling on one or more raceways of the lower guide rail assembly.
  • the door leaf is completely supported on the lower guide rail assembly and the upper guide rail assembly provides only lateral guidance. Still in another embodiment, the door leaf is completely suspended from the upper guide rail assembly with a lower guide rail assembly providing lateral guidance only or without lower guide rail assembly.
  • the distance between the upper guide rail assembly or lower guide rail assembly and the row or rows of permanent magnets has to be adapted to take into account rolling friction between the door leaf and the lower and/or upper guide rail assembly.
  • at least one of the one or more rows of permanent magnets is preferably located closer to the lower guide rail assembly than to the upper guide rail assembly.
  • at least one of the one or more rows of permanent magnets is preferably located closer to the upper guide rail assembly than to the lower guide rail assembly.
  • the guide rail assembly further comprises at least one vertical beam for rigidly connecting the lower and upper guide rail assemblies.
  • the stationary part of the drive means e.g. the flat stators in the case of a linear motor can advantageously be fixed to the vertical beam.
  • an articulated double sliding door assembly comprising two articulated sliding door assemblies as described above for closing a common doorway, the two articulated sliding door assemblies having a common vertical pivot axis fixed relative to the doorway.
  • the two articulated sliding door assemblies can be linked by an interlock for coordinating the motion of the guide rail assemblies of the two articulated sliding door assemblies between their recessed and their protruding positions.
  • a public transportation vehicle in particular a railway vehicle provided with a single or double articulated sliding door assembly as described above, in particular a side door for accessing the vehicle.
  • a doorway 10 in an external side wall 12 of a railway vehicle has two vertical sides 14, 16 and a transom 18.
  • the doorway 10 is equipped with an articulated guide rail assembly 20, which includes an upper guide rail 42 and a lower guide rail 44.
  • the upper guide rail 42 is connected to the transom of the doorway via an upper axial pivot connection 46.
  • the lower guide rail 44 has one end connected to a doorsill 19 of the doorway 10 via a lower axial pivot connection 48.
  • the lower and upper pivot connections 46, 48 define a common vertical pivot axis 50.
  • a coordination linkage 52 between the upper and lower guide rails includes a vertical shaft 54 provided with an upper bell crank 56 linked to the upper guide rail 42 via a connecting rod 58, and with a lower bell crank 60 linked to the lower guide rail 44 by means of a lower connecting rod 62. At least one of the lower and upper bell cranks 56, 60, in this case the lower bell crank 60, is driven by an actuator 64, which can be an electromechanical actuator or a pneumatic cylinder.
  • the vertical shaft 54 rotates about a vertical axis 66 fixed relative to the wall.
  • a vertical flat support beam 68 is attached to the upper and lower guide rails 42, 44 and supports the stators 38, 40 of a linear drive assembly, such that the stators are fixed relative to the upper and lower rails 42, 44.
  • the door leaf 24 is supported on a pair of lower carriages 70 provided with rollers 72, which roll on a horizontal rolling track 74 of the lower guide rail 44.
  • the upper edge of the door leaf 24, illustrated in Fig. 5 is provided with rollers 76, which roll on vertical tracks 78, 80 of the upper guide rail to provide lateral guidance.
  • the door leaf 24 is provided with two rows of permanent magnets 28, 30 at an air gap distance of the stators 38, 40. As illustrated, the rows 28, 30 of permanent magnets and the stators 38, 40 are located at intermediate position between the upper and lower rails 42, 44, closer to the lower rail 44.
  • the assembly operates as follows. In the recessed position in Fig. 1 , the guide rails 42, 44 are in the plane of the doorway 10 closed by the door leaf 24, which is in a first position with respect to the guide rails.
  • the upper and lower guide rails 42, 44 can be locked to the transom and doorsill and/or to the sides of the doorway by positive locking means (not shown).
  • the door leaf 24 is preferably also directly secured to the wall by positive locking means.
  • the locking means are unlocked and the actuator drives the shaft in the clockwise direction in Fig. 2 , so that the upper and lower guide rails 42, 44 rotate about the vertical pivot axis 50 together with the door leaf 24 and the stators 38, 40 to reach a semi open position in which the door leaf 24 has not yet moved relative to the upper and lower rails and 42, 44 is still in the first position.
  • the stators 38, 40 are powered and move the door leaf 24 towards a second, open position.
  • the operations are reversed, with the stators 38, 40 being first powered to drive the door leaf 24 back to the first position, after which the door leaf 24 and drive rails 42, 44 are moved back to the recessed position with the actuator 64.
  • the upper and lower bell cranks 56, 60 can be replaced with two separate levers 70, each of which is articulated at one end with a connecting rod 72 pivotally connected to the corresponding upper or lower rail 42, 44, the other end of each of the two levers 70 being provided with a roller 74 which directly cooperates with the door leaf 24 and is received in a cavity 76 of the door leaf 24 in the first position.
  • This arrangement renders the actuator and vertical shaft unnecessary.
  • the stators 38, 40 of the linear drive are powered to move the door leaf 24 towards the right in Fig. 10.
  • the rollers 74 are pushed out of engagement with the cavities 76 provided in the door leaf and start to roll on the face 78 of the door leaf 24.
  • the levers 70 rotate about their common rotation axis 80 and push the connecting rods 72 and the upper and lower guide rails 42, 44, which rotate about the fixed pivot axis 50.
  • a spring 82 or another type of return means e.g. an electromagnetic return means can be added to bias the rails towards the recessed position.
  • the articulated sliding door assembly can be provided with two symmetrical door leafs 24, each provided with its own linear drive.
  • one row 28 of permanent magnets located in the upper half of the door leaf 24 and the other row 30 located in the lower half, or at least to have the two rows 28, 30 spaced apart from one another by a distance of more than 1/10 of the door leaf height. It becomes possible to control the two stators 38, 40 such as to balance the effects of resulting magnetic forces on the upper and/or lower guide rails.
  • the linear motor can be replaced with alternative driving means, e.g. a rotary motor having its output shaft directly or indirectly connected to a pinion of a rack and pinion system.
  • alternative driving means e.g. a rotary motor having its output shaft directly or indirectly connected to a pinion of a rack and pinion system.
