Description

Field of the Art of the Invention This invention relates to a sliding door assembly, in particular, but not exclusively, for a public transport vehicle such as a rail vehicle.

BACKGROUND ART The exterior door and interior sliding door assemblies for rail vehicles are usually provided with electro-pneumatic or electro-mechanical driving means which require a substantial amount of space directly above the door leaf at the crossbar level and upper guide rail. from the door

[003] It has been suggested in EP 1,681,426 to operate a sliding door by means of a linear motor. The stator consisting essentially of a row of interconnected electric coils is arranged above a sliding door leaf in a specific space provided in a longitudinal cavity of a fixed guide rail and guide rail. The door leaf is provided with one or more roller trolleys which roll in the corresponding straight channels of the support and guide rail. At least one of the cars is provided with a row of permanent magnets that faces the row of electric coils with a reduced air space. While such an arrangement offers an alternative to the more conventional electropneumatic or electromechanical driving means, it does not substantially reduce the space required to accommodate the driving means in the region of the door opening member. In addition, access to the electromagnetic circuit for maintenance purposes is particularly difficult.

[004] Therefore, there is a need for an alternative means of driving that requires no space in the door crossbar region and which is easier to access.

Summary of the Invention In accordance with one aspect of the invention, a sliding door assembly is provided comprising: - a door leaf having an upper horizontal edge and a lower horizontal edge; an upper guide rail assembly for guiding the upper edge of the traversing door leaf parallel to a horizontal sliding direction relative to the upper guide rail assembly between a first end position and a second end position; - one or more rows of the first magnetic field generating elements attached to the door leaf, each row extending horizontally and located at an intermediate position below the upper horizontal edge and the upper guide rail and above one edge. lower horizontal of the door leaf with each row consisting of adjacent poles of alternating polarities; - one or more stators each associated with one of the rows of the first magnetic field generating elements and each comprising a second magnetic field generating element located at an associated row airspace distance between the rows. of the first magnetic field generating elements to generate an induced electromagnetic force in the sliding direction in the associated row within the rows of the first magnetic field generating elements, wherein one or more stators are stationary relative to the upper guide rail assembly. and overlap one end of the rows of the first magnetic field generating elements in the first position.

Due to the location of the row or rows of first magnetic field generating elements, the structure of the upper guide rail assembly can be simplified and made more complete so that more space is available above the door leaf.

As will be readily understood, the stators are located at the same height as the associated rows of the first magnetic field generating elements, so that they do not require additional space at the upper guide rail assembly level. Access to stators is particularly easy for maintenance purposes. The overall concept is particularly reliable as the upper rail assembly is independent and separate from the driving means.

Preferably, the one or more stators are facing and overlapping one end of the rows of the first magnetic field generating elements near a first vertical edge of the door leaf to generate an electromagnetic force in the first position. . During subsequent movement toward the second position, the rows of the first magnetic field generating elements progressively move past the associated stators so that when the gate reaches the second position, the stators are turned to and overlap with a second end. from the rows of the first magnetic field generating elements near a second vertíeaf edge of the door leaf.

According to a preferred embodiment, the 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 the first magnetic field generating elements are preferably each located above the lower guide rail assembly so that the lower guide rail assembly can be kept simple and compact.

The door leaf is preferably at least partially and preferably completely supported on rollers which roll on one or more shanks of the lower guide rail assembly.

According to a preferred embodiment, the upper guide rail assembly may consist, as is well known in the art, of a rail provided with one or more shanks in which the rollers attached to the door leaf may roll. Particularly, the door leaf may be at least partially and preferably completely supported from one or more carts rolling on one or more cages of the upper guide rail assembly.

[012] In a particular embodiment, the door leaf is fully supported on the lower guide rail assembly and the upper guide rail assembly provides lateral orientation only. In yet another embodiment, the door flap is completely suspended from the upper guide rail assembly with a lower guide rail assembly providing lateral orientation only or without the lower guide rail assembly.

[013] The distance between the upper guide rail assembly or the lower guide rail assembly and the row or rows of the first magnetic field generating elements has to be adapted to take into account the rolling friction between the door leaf and the lower and / or upper guide rail assembly. In the case of a fully supported door leaf, for example, at least one of one or more rows of permanent magnets is preferably located closer to the lower guide rail assembly than to the upper guide rail assembly, for example. , at a distance of approximately 10 to 30 cm above the lower guide rail assembly of the door leaf, while another optional permanent magnet string may be located at a greater distance from the lower guide rail assembly, for example, between the first row permanent magnets and the average reading of the door leaf. Conversely, in the case of a fully suspended door leaf, at least one of one or more rows of permanent magnets is preferably located closer to the upper guide rail assembly than to the lower guide rail assembly, e.g. approximately 10 to 30 cm below the upper guide rail assembly, while another optional row of permanent magnets can be located a greater distance from the upper guide rail assembly, for example, between the first row of permanent magnets and the average height of the door leaf, If for any reason the permanent magnet rows are not ideally placed relative to the guide rail assembly, compensation can be provided with two permanent magnet rows located at different heights if the stators associated with the two rows are controlled such as to induce both a resulting electromagnetic force in the sliding direction when a torque to balance the momentum of mechanical resistance of the guide rail assemblies.

According to one embodiment, one or more rows of the first magnetic field generation elements include at least two rows of the first magnetic field generation elements and each of the two rows of the first magnetic field generation elements consists of at adjacent poles of alternating polarity distributed such that when the stator associated with one of the two rows faces one of the poles, the stator associated with the other between the two rows faces a space between the two adjacent poles.

According to one embodiment, the first magnetic field generation elements of each row consist of individual permanent magnets and the one or more second magnetic field generation elements include one or more electrical windings. [018] Preferably, the Electrical windings of the first and / or second magnetic field generating elements are energized only when necessary, ie only to generate the electromagnetic forces to open and close the door leaf. Therefore, when the door is stationary, no substantial electromagnetic field is generated which reduces eietromagnetic interference with the environment.

According to one embodiment, the upper guide rail assembly is fixed relative to a wall including an entrance closed by the door leaf. In this case, the door hash only moves in transition. The first position is the closed position and the second position is the open position. This embodiment is particularly suitable for an interior door or compartment door in a rail vehicle.

According to another embodiment particularly suitable for a side door of a rail vehicle, the door leaf assembly further comprises a connection for guiding the upper guide rail with respect to an entry in a wall between a closed position and a closed position. The door is closed by the door leaf when the upper guide rail is in the closed position and the door leaf is in the first position. The entrance is fully open when the upper guide rail assembly has moved to the half open position and the door leaf has moved to the second position. As stated above, the stator or stators are preferably fixed relative to the upper guide rail means. Advantageously, the connection permits a pivoting movement of the guide rail assembly about a vertical pivot geometric axis. The vertically pivoting geometric axis is preferably fixed relative to the inlet. The door washer assembly is provided with a lower guide rail means and one or more coordinating bars may extend between the upper and lower guide rail assemblies.

[019] Independent driving means may be provided to move the upper guide rail assembly between the closed and half-open position. Alternatively or additionally, the connection may further comprise a coordinating connection for coordinating a transitional movement of the door leaf relative to the upper guide rail assembly and a movement of the upper guide rail relative to the inlet.

According to another aspect of the invention, a rail vehicle is provided which includes a sliding door assembly as defined above.

According to one embodiment, the door leaf includes a panel! at least one of one or more rows of the first magnetic field generating elements is located in the transparent panel substantially at eye level or elbow height. More specifically, the row may be located at a height between 1,500 mm and 2,000 mm, preferably between 1,500 mm and 1,800 mm. As an option, a second row can be located at a height between 850 mm and 1,000 mm. Each row preferably has a height of at least 100 mm.

[022] The row of the first magnetic field generating elements may be provided as a magnetic sheet applied to the transparent panel surface. It can also be integrated into the transparent panel.

[023] To provide even more contrasting door marking, at least one of one or more rows of the first magnetic field generating elements may be colored in at least two contrasting colors and / or specific patterns.

[024] Various embodiments of the invention may be combined at will.

According to another aspect of the invention, a public transport vehicle is provided, in particular a rail vehicle with a sliding door assembly as described above, particularly as the interior partition door at the end of a hall or passenger compartment. .

Detailed Description of the Preferred Embodiments Referring to Figures 1 to 4, an inlet 10 in a partition wall 12 of a rail vehicle, for example a hall or compartment entrance, has two vertical sides 14, 16 and one cross member 18. The cross member 18 is equipped with a fixed guide rail assembly 20 fitted in the channels 22 which define a linear path. A door leaf 24 is suspended from two trolleys 26 provided with rollers 27 which roll on the guide rail 22 of the guide rail assembly 20 in a known manner, so that the door leaf 24 can slide between a closed position shown in the illustration. Figure 1 is an open position illustrated in Figure 2, parallel to the linear path of channel 22 and a sliding direction 100.

Door leaf 24 is provided with two rows 28, 30 of the first magnetic field generating elements, which are illustrated as permanent magnets, but may also be electrical windings. Each row consists of individual 28N, 28S, 30N, 30S alternating north and south poles, which may be made with individual magnets or with a continuous band of rigid or flexible material filled or otherwise charged with magnetic, preferably ferromagnetic, oriented particles. such as to provide a succession of sections of alternating magnetization directions. In the example, the individual U-shaped permanent magnets 28M, SOM are incorporated in the door leaf 24 with the ends thereof 28N, 28S, 30N, 30S flush with the door leaf surface 32. Each row 28, 30 forms a so-called “unwound motor” of a multipolar linear synchronous motor.

A side 16 of the inlet 10 is provided with a slot 34 to accommodate the door leaf 24 in the open position. At the height of each of the two rows 28, 30 of permanent magnets, the slot is provided with two stators 38, 40, each of which includes several bearings 38W, 40W and armature 38A, 4QA. Each stator 38 and 40 is associated with one of the two cookers 28 and 30 and its windings 38W, 40W, which constitute second magnetic field generating elements, are directed to the associated row 28 and 30 at an airspace distance D.

Each pole 30S, 30N of the second row 30 of permanent magnets is located vertically between the two adjacent pots 28S, 28N of the first row 28 of permanent magnets. The windings 40W of the second stator 40 are vertically aligned with the windings 38W of the first stator 38. Therefore, when one of the windings 38W of the first stator 38 faces one of the poles 28S, 28N of the first row 28, the aligned winding 40W of the second Stator 40 is located between two poles 30S, 30N of the second row 30.

[032} The windings of the two stators are quadrature energized, that is, with a phase difference of 90 ° (π / 2 radians). Depending on which of the stators leads in the phase, the door leaf will move in one direction or the other.

The embodiment of Figures 5 to 9 differs from the embodiment of Figures 1 to 4 wherein the guide rail assembly 20 is movable relative to the wall and inlet. As will be explained below, this different structure of the guide rail assembly 20 involves a different positioning of the stators 38, 40 and rows of permanent magnetic pots 28, 30.

More specifically, an inlet 10 in an outer sidewall 12 of a rail vehicle has two vertical sides 14, 16 and a crossmember 18. The inlet 10 is equipped with a hinged guide rail assembly 20 which includes a guide rail 42 and a lower guide rail 44. The upper guide rail 20U is connected to the inlet rail by means of an upper axial pivot connection 46. Similarly, the lower guide rail 44 has an end connected to an inlet 19 10 by means of a lower axial pivot connection 48. The lower and upper pivot connections 46, 48 define a common vertical pivot geometric axis 50. A coordinating connection 52 between the upper and lower guide rails includes a vertical axis 54 provided of an upper angled lever 56 connected to the upper guide rail 42 by means of a connecting rod 58 and with a lower angled lever 60 attached to the lower guide rail 44 by that of a lower connecting rod 62. At least one of the lower and upper angular levers 56, 60, in this case the lower angular lever 60, is driven by an actuator 64, which may be an electromechanical actuator or a pneumatic cylinder. The vertical axis 54 rotates about a vertical geometric axis 66 fixed relative to the wall. A vertical flat support bar 68 is attached to the upper and lower guide rails 42, 44 and holds the stators 38, 40 of a linear guide assembly so that the stators are fixed relative to the upper and lower rails 42, 44. As shown in Figure 8, the door leaf 24 is supported on a pair of lower carriage 70 provided with rotets 72, which roll on a horizontal bearing rail 74 of the lower guide rail 44. The upper edge of the door leaf 24, illustrated 9 is provided with rollers 76, which roll on vertical rails 78, 80 of the upper guide rail to provide lateral orientation. Door leaf 24 is provided with two rows of permanent magnets 28, 30 and an airspace distance of the stators 38, 40. As shown, the permanent magnet rows 28, 30 and the stators 38, 40 are located in position between the upper and lower rails 42, 44, closest to the lower rail 44. {035] The assembly operates as follows. In the closed position in Figure 6, the guide rails 42, 44 are in the plane of the inlet 10 closed by the door leaf 24, which is in a first position relative to the guide rails. The upper and lower guide rails 42, 44 may be locked to the crossmember and / or inlet lugs by positive locking means (not shown). The door leaf 24 is preferably also attached directly to the part by positive locking means.

[036] In order to open the door, the locking means are unlocked and the actuator drives the shaft clockwise in Figure 7, so that the upper and lower guide rails 42, 44 rotate about the vertical pivot shaft 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. Once this movement has been completed, the stators 38, 40 are fed and move the door leaf 24 toward a second open position.

[037] In order to close the door, operations are reversed, with the stators 38, 40 being first fed to drive the door leaf 24 back to the first position, after which the door leaf 24 and the railings 42, 44 are moved back to the closed position with actuator 64.

According to a variant illustrated in Figure 10, the upper and lower angled levers 56, 60 may be replaced by two levers 70, each of which is pivoted at one end with a connecting rod 72 pivotally connected to the upper rail. or corresponding lower 42, 44, wherein the other end of each of the two levers 70 is provided with a roller 74 which cooperates directly with the door leaf 24 and is received in a cavity 76 of the door leaf 24 in the first position. This arrangement makes the actuator and vertical axis unnecessary. To move the door from the closed position to the open position, the linear driving stators 38, 40 are fed to move the door leaf 24 to the right in Figure 10. In the first few inches of the sliding movement of door leaf 24, the Rollers 74 are pushed out of the engagement with the cavities 76 provided in the door leaf and begin to roll on face 78 of door leaf 24. Simultaneously, levers 70 rotate about their common axis of rotation 80 and push the connecting rods. 72 and the upper and lower guide rails 42, 44, which rotate about the fixed geometric axes 50. In order to close the door, the operation is simply reversed. A spring 82 or other type of return means, for example, an electromagnetic return means may be added to divert the rails to the closed position. In another embodiment, the sliding door assembly may be provided with two symmetrical door leaves 24 each having their own linear conduction.

[040] According to a variant of the first embodiment, particularly suitable for an interior partition door of a passenger rail vehicle, the door leaf includes a transparent panel, for example a glass panel and two permanent magnet rows. they are located at different heights inside or over this glass panel so as to be clearly visible. More specifically, a row of permanent magnets is located on the transparent panel substantially between eye height and elbow height, for example at a height between 1,500 mm and 2,000 mm, preferably between 1,500 mm and 1,800 mm. Optionally, the second row can be located at a height between 850 mm and 1,000 mm. Each row preferably has a height of at least 100 mm. The rows of permanent magnets 28, 30 may be painted in different colors as shown in Figures 11A to 11E.

More generally, it may be proved advantageous in all embodiments to have a 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 separated from each other by a distance of more than 1/10 from the height of the door leaf. It becomes possible to control both stators 38, 40 as well as to balance the effects of the resulting magnetic forces on the upper and / or lower guide rails.

[042] In all embodiments, the permanent magnets 28M, SOM of the two rows 28, 30 can be replaced by electrical windings to form the first magnetic field generating elements. In such a case, the windings 38W, 40W constituting the second magnetic field generating elements of the two stators 38, 40 may be replaced by permanent magnets. In the embodiment of Figure 12, the door leaf is equipped with one or several rows 28 of windings 28W, which face a stator 38, which includes two permanent magnets 38M which provide two pairs of alternating poles 38N, 38S. In the embodiment of Figure 13, both the first magnetic field generating elements fixed relative to the door leaf and the second magnetic field generating elements fixed relative to the upper guide rail assembly consist of windings.

In all embodiments, windings 28W, 38W, 40W are preferably energized only when necessary, ie to generate electromagnetic forces to open or close the door leaf.
