Abstract

The motorised door of a railway vehicle comprises a door leaf (4) which fits in a bay (5) when closed by sliding longitudinally. The operating device comprises a suspension beam (17) with a transverse linear guide (13) comprising sliding runners fixed to it. An electric motor (6) is mounted on the beam. The door leaf longitudinal transmission system (16) comprises two pulleys connected to the motor output shaft and a belt connected to the door leaf. The motor output is connected to an articulation which enables a pre-specified transverse travel of the beam and can be rotationally locked to prevent the door moving in the closed position.

Description

The invention relates to the technical field of motorized doors, in particular for a railway vehicle, with at least one leaf that can be inserted approximately transversely into a frame in the closed position and can be moved approximately longitudinally along a wall of the vehicle in which the frame is provided.

More specifically, their objects are a door operating device, a door equipped with this device and a rail vehicle equipped with at least one of these devices and/or doors.

In the examples, the invention is applied to a double door, each leaf of which follows a direct "intersecting-sliding" path.

However, doors with one or more leaves, which can be moved along other paths allowing them to be inserted into the frame, also fall within the scope of the invention.

The publications in the technical field of the invention should be taken into account.

The publication DE-B-2.219.176 describes a torsion stabilizer for sliding doors with hinged telescopic slide rails on at least one pivot lever with guides for fixed bearings.

Document FR-A-2.294.306 describes a door with sliding movement.

The document EP-A-001.956 describes a guide and control device for a sliding door.

The publication GB-A-2.159.208 describes a door arrangement driven by a drive belt guided around deflection rollers.

Document FR-A-2.621.879 describes an intersecting-sliding door with a connecting rod. Document US-5483769 describes an intersecting-sliding door operating device according to the preamble of claim 1.

The known state of the art has disadvantages.

For example, document EP-A-400.188 describes a double door in which the motorization is transversely fixed in relation to the frame. A motorization drive belt is connected to each leaf by a rigidly mounted arm.

This door does not allow symmetrical movement of the leaves. Adjustments can only be made after the leaves have been installed on the vehicle. When the leaves are unhooked from the frame, the drive belt is deformed transversely.

According to the document GB-A-2.159.208, the drive belt is firmly connected to the transverse movements of the wing by a complex arrangement. The guide span of the wing in the longitudinal direction is limited, which gives it insufficient support, a so-called guide flexibility. Here too, the adjustments can only be made after the wing has been mounted on the vehicle.

The invention aims in particular at eliminating these disadvantages.

It aims to obtain a door operating device with a reduced number of components and connections between fixed and mobile parts.

Thus, starting from identical components, certain characteristics of the door, in particular its longitudinal dimensions, can be modulated.

The device also allows a secure blocking of each leaf in the closed position with a small number of simple components.

To this end, one of the objects of the invention is a motorized door operating device, particularly intended for a rail vehicle, comprising at least one leaf intended to be inserted substantially transversely into a frame in the closed position and to slide substantially longitudinally along a wall of the vehicle in which the frame is recessed.

This device comprises in combination the features of claim 1.

It becomes clear that the suspension beam is a stiff, simple and light component, for example a Single component which allows the preservation of a limited and practical cutting surface for the mounting of the beam on the vehicle on the one hand.

On the other hand, the beam allows the integration of most of the components of the operating device, including the motor, the transmission and the transverse and longitudinal guides and thus the suspension of the leaf.

This prevents transverse deformation of the drive belts, simplifies the realization of a modular door while allowing the door to be adjusted before its installation, for example in the factory.

Other features of the embodiments of the device are set out.

The anchoring means comprise two support plates designed to be applied against and rigidly fixed to the wall and/or a horizontal plane of the vehicle.

The suspension beam of the wing is essentially formed by a rail of the longitudinal guide means, for example a telescopic slide rail in a horizontal "U" shape with a concavity fixed transversely and rigidly to the transverse guide means by means of screws or the like.

The transverse guide means comprise at least one slide rigidly attached to the anchoring means on the one hand and to the suspension beam on the other hand, for example these means comprise two cylindrical transverse slides, each with a raised shoulder with an external transverse extremity.

The transverse guide means comprise a locking system allowing the longitudinal and/or transverse positioning and/or the elevated positioning of the wing, possibly via the longitudinal guide means.

The transverse guidance means comprise a transverse stop which restricts an extremity and is referred to as an inner stop which limits the predetermined transverse path.

The joint arrangement at the output of the motorization means includes:

- a radial arm rigidly attached to an output such as a body or electric motor stator;

- a roughly elongated rod pivotally mounted at a distance from the outlet of the radial arm; and

- a locking lever hinged to the suspension beam.

One leg of the lever is connected to the rod so as to pivot relative to the arm, while its other leg has a recess in which a finger is firmly connected to the anchoring means and engages a specific finger for blocking support against a transverse surface of the recess.

In this way, the rotation of the output and the radial arm causes a transverse displacement of the suspension beam which is interrupted according to a direction of rotation of the output by a stop after exceeding the strut of the articulation assembly between the rod, the output or body and the lever after a predetermined travel.

In the opposite direction of rotation, the run is limited by the entry of the transverse guide means into the stop against the transverse surface opposite that of the recess.

The longitudinal transmission means include:

- a roller fixed coaxially to an output, such as the shaft of the motor means;

- two rollers of elevation axis fixed to the suspension beam;

- a belt with approximately elongated strands, engaging with the rollers and the output of the motorization means and the output of the motorization means, at least one strand being connected to the wing, for example via a clamping jaw;

- tension rollers whose elevation axes are mounted approximately parallel to that of the roller (35) at the output of the motor means, on both sides in the longitudinal direction.

In this way, the tension rollers and the pulleys at the output clamp and drive a strand of the drive belt in an active state of the motorization means.

According to an embodiment intended for a double door, an articulated connection arrangement connects a carriage of the transverse guide means, longitudinally remote from the locking means, to another carriage in such a way as to cause their simultaneous and identical transverse displacement.

The hinged connection arrangement of the wings includes:

- a cam hinged to the suspension beam about an axis of elevation in the longitudinal direction near the carriage at a distance from the locking means;

- a finger with a transversely inclined recess, which rotates together with the cam;

- a block fixed to the anchoring means at a distance from the locking means and connecting the latter means transversely to the recess of the finger;

- a crosshead, near the other carriage, pivotally mounted on a lever belonging to the motorising or locking means, so as to be displaced longitudinally under their action;

- a rigid, slightly elongated rod, articulated around an axis of elevation around the cam and fixed to the crosshead in order to connect them during the longitudinal displacements of the latter.

According to one embodiment, the crosshead is firmly connected to the motorization means via the locking means and in particular a blocking lever of these means.

The motorization means include a flexible or analogue supply.

The suspension beam comprises means for arranging modular elements suitable for adapting the operating device by means of selected components according to the intended door.

Another subject of the invention is a door, for example with a higher edge of its frame, equipped with an operating device as mentioned above.

This door is installed in a wall in which the frame is provided and whose anchoring means are rigidly connected, for example by screws.

Other features of the design of such a door should be taken into account.

The door further comprises connecting means connecting a longitudinal edge of the leaf, such as the upper one, to an opposite edge in elevation, such as the lower one, for example these means comprise a rigid raised pin and/or a flexible system connected longitudinally by the levers with rollers to the ramps firmly connected to each edge of the leaf.

Yet another object of the invention is a rail vehicle equipped with at least one device and/or a door as mentioned above.

The invention is described in more detail in the following description and with reference to the accompanying drawings.

In these drawings, Fig. 1 is a perspective front view of an inner door with two leaves in maximum position, equipped with an actuating device according to the invention and the connecting means.

Fig. 2 is a view similar to Fig. 1, showing the door according to the invention in the closed opening position with its leaves inserted in the frame.

Fig. 3 is a partially sectional perspective front view according to line III of Fig. 2, illustrating the structure of the actuating device of an embodiment.

Fig. 4 is a view according to the direction of elevation and from top of the door of Fig. 1 in the open position.

Fig. 5 is a view similar to Fig. 4 with the door in the closed position.

Fig. 6 is a front view from below of the door of Fig. 1 with its wings opened.

And Fig. 7 is a view similar to Fig. 6 with the wings inserted, i.e. in the closed position.

The figures show three indication directions L, E and T which are perpendicular to each other.

The so-called longitudinal direction L is considered to be clearly horizontal.

The so-called transverse direction T is also considered to be clearly horizontal. In contrast, the so-called elevation direction E is considered to be clearly vertical.

Except in cases of local alignments, the terms "longitudinal" and "transverse" refer, respectively, to the longitudinal direction L and the transverse direction T.

And the terms "upper" and "lower" are considered upwards and downwards according to the elevation direction E.

While the terms "inner" and "outer" are considered according to the transverse direction T and refer to the right and left sides in Fig. 3, respectively.

Finally, the terms "front" and "rear", unless otherwise stated, are considered according to the longitudinal direction L from the left and right in Fig. 1, respectively.

The directions L, E and T are used here to describe the components of the invention in their usual main positions of implementation.

In particular, the case of a door in an external partition of a rail vehicle, such as a wagon, which extends only along the longitudinal direction L and the elevation direction E of the vehicle, the latter sliding substantially along the longitudinal direction L, is considered.

However, the door of the invention can be arranged at different locations of the vehicle and, for example, inside the cabin of a vehicle or for closing a partition wall extending transversely or in elevation.

It goes without saying that the components of the invention may assume different positions or orientations in space, in particular during their operation, manufacture, transport or storage.

The directions L, E and T are therefore orientation values and serve only for explanatory purposes.

In Figs. 1 and 2, the reference 1 designates in general a vehicle, and in particular a partition or wall 2 of this vehicle 1.

To allow access through wall 2, it is equipped with a door 3.

As can be seen from the figures, it can be assumed that the door 3 and the partition wall 2 extend essentially and generally in the longitudinal direction L and the elevation direction E.

However, according to the direction E, a door according to an embodiment of the invention (not shown) has certain transverse orientations.

The door 3 comprises posts, which here coincide with the wall 2 for the sake of simplicity, and two leaves 4.

The invention is of course also applicable to doors 3 provided with only one leaf 4.

The wall 2 is provided with a recess or frame 5 which is substantially or completely exposed by the leaves 4 in the opening position or open position of the door 3, as shown in Fig. 1.

While the leaves 4 of the door 3 in the closing position (or closed position) as shown in Fig. 2 are integrated in the frame 5 and close it.

The outer contour of each wing 4 is therefore clearly complementary to the inner contour of one half of the frame 5 according to the longitudinal direction L, the elevation direction E and the transverse direction T (for example, for the operating and resting play when opening/closing).

Here each wing 4 is clearly rectangular, as can be seen according to the direction T.

The door 3 shown is a motorized door, i.e. it is provided with motorization means 6 for moving the leaves 4 for opening and/or closing them.

In the examples, the means 6 comprise an electric motor.

We have seen that door 3 of the figures is a door with "intersecting-sliding" path.

Referring to Figs. 4 and 5, it is noted that the wings 4 extend clearly along the longitudinal direction L in the closed and open positions.

Each wing 4 is guided from its open position to its closed position according to an arrow F or F'.

The front edge 7 of a wing 4 is the edge that is located on the front side of the wing in the direction of the closing movement F or F'.

In a double door 3 it is clearly located in the elongated middle.

The wing 4 then follows an insertion path into the frame 5 close to a translational displacement in a curved line inwards.

After carrying out this insertion, the wing 4 is in a plane parallel to the elevation direction E and to the longitudinal direction L between an elevation post 8 and an elevation post 10 of the frame 5, both opposite according to the direction L (Fig. 2).

Thus, the wings 4 are inserted into the frame 5, thereby closing it.

A device 11 referred to as door operation is provided on the door 3 of the rail vehicle 1.

The device 11 comprises in particular:

- anchoring devices intended for mounting the door 3 on the wall 2;

- a suspension beam 17 of the wings 4;

- linear transverse guide means 13 allowing the wings 4 to be guided for locking-insertion and opening-unhooking;

- guide means 14 in the longitudinal direction of the wings 4;

- means for motorising the wings 4, in the figures the electric motor 6;

- locking means 15 provided in rotation to allow or prevent the transverse displacement of the suspension beam 17; and

- Means 16 for transmitting movement to the wings 4 in longitudinal direction.

It should be noted that the transverse guidance means 13, the longitudinal guidance means 14, the motorization means 6, the locking means 15 and the longitudinal transmission means 16 are integrated on the suspension beam 17. The latter is itself connected to the vehicle 1 by anchoring means 12.

In the figures, the anchoring means 12 intended for mounting the door 3 on the wall 2 comprise two support plates 18.

These plates are intended to be applied against a horizontal plane, not shown, of the vehicle 1 and are rigidly fixed to the latter and thus to the wall 2, which is part of the same structural arrangement as the horizontal plane in question.

Fig. 3 shows that the suspension beam 17 is essentially formed by a support rail, which is a component of the guide means in the longitudinal direction 14. This rail, also designated 17, is a component of a telescopic slide rail connected to the wings by means of balls 19 and intermediate rails in the longitudinal direction 20.

There are two intermediate rails 20. Each is connected to a wing 4 which it supports.

The support rail of the means 17 has a horizontal "U" shape with a concavity directed transversely to the outside of the door 3. In certain designs, this rail is directed inwards.

In certain designs, the concavity is directed inwards, which can limit the contamination of the slide rails.

This support rail is rigidly attached to a shoulder 21 of the transverse guide means 13 visible in Fig. 4 by means of screws (not shown).

The latter, also referred to as unhooking means 13, have, on the one hand, a part rigidly attached to the anchoring means and, on the other hand, another part attached to the suspension beam 17.

The transverse guide means 13 comprise, on the one hand, two slides 22 guided in relation to the anchoring means 12.

On the other hand, the slides 22 are attached here to the suspension beam 17 in order to firmly connect them to one another in transverse displacement.

In certain embodiments, a joint unit, for example with a longitudinal axis, is arranged between the beam 17 and each carriage 22.

In the figures, the carriages 22 each comprise a cylindrical rod that is firmly connected transversely to the beam 17 and is mounted so as to slide in the guide seat of the rod that is firmly attached to a plate 18. They form a linear, rectangular and transverse guide.

Each carriage rod is provided, as described above, at a transverse outer end of the device 11 with a shoulder 21 for firmly fastening the beam 17.

Fig. 3 shows that the transverse guide means 13 further comprise a positioning system 23.

The system 23 allows a precise mutual localization according to the longitudinal direction and/or the transverse direction and/or the elevation direction of the wings 4 in relation to the device 11. Here, the system 23 belongs to a hooking device.

Thanks to the suspension beam 17, the device 11 is suitable for being mounted on the vehicle 1 by simply connecting the support plates 18 against the corresponding parts of the vehicle 1.

The wings 4 are positioned by means of guide means in the longitudinal direction 14 and more precisely of the beam or the rail 17 against the shoulder 21.

In the embodiment shown, the positioning system provides on the step 21 an elongated groove 21 with which a projection of complementary shape in the elongated inner elevation side of the beam 17 cooperates.

Screws not shown allow the maintenance of the structure of beam 17 and shoulder 21 of means 13.

In order to also ensure that the wings 4 are held firmly on the intermediate rails 20, the latter are provided with fastening means 25 in Fig. 3.

It should also be noted that, particularly in Fig. 5, a slide rod 22 is provided with a transverse stop 26 at its inner free end and therefore transversely to the beam 17.

The stop 26 limits the inner end of the transverse predetermined course of the beam 17.

The motorization means 6 have an output 27 (Fig. 6 and 7) which is effectively formed by an elevation axis.

An output 27, here the shaft of the motor 6 connected to its rotor, passes through a plate 28 by which the motorization means 6 are rigidly mounted on the suspension beam 17.

The motor body of the means 6 is connected to a joint arrangement 29.

The pivot arrangement 29 is clearly visible, particularly in Figs. 4 and 5.

It should be noted here that the locking means 15 allow the blocking of the articulation unit 29 in rotation.

The locking means 15 are, in an inactive state, suitable for allowing a transverse displacement of the predetermined course of the suspension beam 17.

This transverse displacement is prevented by locking means 15 in their active state.

In particular in Fig. 4, the articulation arrangement 29 comprises a radial arm 30 rigidly attached to the motor body of the means 6.

A rod 31 of the structure 29 shown in the figures with a slight inclination in relation to the longitudinal direction L is considered to be clearly elongated.

The rod 31 is pivotally mounted at a distance from the motor body at the free end of the radial arm 30.

The joint arrangement 29 also comprises a blocking lever 32 which is particularly articulated on the suspension beam 17.

In Fig. 4 to 7 it (32) clearly has a triangular shape, one tip of which is turned inwards.

One leg of the lever 32 is pivotally connected to the rod 31 relative to the arm 30.

The other leg of the lever 32 includes a recess 33.

The recess 33 is transversely secured to the anchoring means 12 by means of a pin 34 provided here with rolling means in the recess.

In Fig. 7, the orientation of the recess from the left front side to the right rear side of the door 3 is in the order of 20 to 30º in relation to the longitudinal direction L.

The pin 34, integral with the anchoring means 12, is arranged to rest on the blocks against a transverse surface of the recess 33 or where it is housed.

In this way, the rotation of the motor body and of the radial arm 30 is capable of causing a transverse displacement of the suspension beam 17.

This displacement is interrupted according to a direction of rotation of the motor body by a stop after exceeding the hanging of the joint arrangement 29 between the rod 31, the motor body and the lever 32.

A safety system allows the suspension point for closing to be exceeded when the door 3 is to be operated manually without the assistance of the means 6.

Here, the system comprises a torsion spring mounted on the joint unit between the rod 31 and the blocking lever 32, so that the other joint unit of the rod 31 is addressed inwards (Fig. 5).

In the reverse direction of rotation, the run is limited by the beginning of the stop of the transverse guide means 13 against the transverse surface or the stop 26.

This stop 26 is located in the transverse direction T opposite the recess 33.

Now the means of transmission in the longitudinal direction 16 of the movement to the wings 4 will be described.

We have seen that they are mounted on the suspension beam 17.

The movements of the wings 4 can be combined from a rotation of the motorization means 6.

The longitudinal transmission means 16 are described with reference in particular to Figs. 5, 6 and 7.

In Fig. 6, a roller 35 of these so-called output means 16 is fixed coaxially on the shaft or at the output 27 of the motorization means 6.

In Fig. 5 you can see two rollers 36, one at the front and one at the back (left and right), whose elevation axes are mounted on the suspension beam 17.

The reference number 17 designates a drive belt whose strands are clearly elongated.

In the figures, it is a drive belt 37 that is toothed inside the loop it forms.

The output rollers 35 and front and rear rollers 36 therefore comprise on an outer guide surface to toothings of the drive belt 37 complementary teeth.

In Fig. 5 and 6 it can be clearly seen that the drive belt 37 engages with the rollers 35, 36 and 39.

An elongated, here inner, strand is connected to the front wing 4, while an outer strand is connected to the rear wing 4.

Fig. 7 shows the clamping jaws 38 mounted at the end of the arms attached to each of the wings.

Each of these clamping jaws clamps a lower or outer strand of the drive belt 37 so that a front wing 4 is driven towards the front side when these strands are displaced and a rear wing 4 is driven towards the rear side of the door 3.

Fig. 6 also shows the tension rollers.

These tension rollers 39 are mounted on the motor support plate 28 by means of elevation axes, at least one of which is adjustable. The axes of the rollers 39 are thus arranged parallel to those of the output 27 and on each side of the roller 35 carried by this output.

In other words, the axes of the tension rollers 39 and the roller 35 are clearly arranged according to the longitudinal direction L.

This arrangement of the rollers 39 and the output roller 35 allows the clamping and driving of the inner strand of the drive belt 37.

The clamping is achieved by a proximity effect using at least one of the axes of the tension rollers 39 to the the roller 35 or adjustment means moving away from it. Here only the axis of the rear roller 39 is adjustable (Fig. 5).

This approach and trapping effect is permanent.

In an active state of the motorization means 6, the arrangement of the rollers 35 and tension rollers 39 causes the driving along the longitudinal direction L of the strands of the drive belt 37 in two respectively opposite directions.

In Figs. 5 and 7, it is noted that the door 3, which is double, comprises a hinged connection arrangement 40.

The arrangement 40 connects the rod of a carriage 22, which is longitudinally remote from the locking means 15, to another carriage 22.

The function of this arrangement 40 is to cause the transverse, simultaneous and identical displacement of the slide rods 22 and, consequently, of the beam 17 and the wings 4.

Figures 5 and 7 show that the assembly 40 comprises a cam 41 mounted so as to pivot about an elevation axis. The cam 41 is hinged on the beam 17. It is located longitudinally near the carriage, away from the locking means 15.

A finger 42 of the arrangement 40 is firmly connected in rotation to the cam 41. In Fig. 7 it can be clearly seen that this finger 42 has a transversely and longitudinally inclined recess. In the figure, the finger 42 and the cam 41 are part of one and the same piece.

In relation to the longitudinal direction L, the orientation of the recess of the finger 42 and that of the recess 33 form a triangle with an elongated base, one tip of which is directed towards the inside of the door 3.

This triangle is so clearly symmetrical in relation to the transverse direction T that the alignment angles of the recesses 33 and the finger 42 are comparable or clearly the same.

A block 43 is also part of the arrangement 40. The block 43 is rigidly attached to the anchoring means 12, remotely from the locking means 15.

It transversely connects the recess of the finger 42 and the means 12. When the finger 42 is driven in rotation about the common axis of the cam 41, the block 43 thus functions as a fixed point and causes the displacement of the beam 17 in the direction T.

A crosshead 44 of the arrangement 40 is arranged near the other carriage 22. In a horizontal plane, as in Fig. 5, the crosshead has the shape of a crescent with concavity directed towards the inside of the door 3. The concavity of the crescent surrounds the means 6.

The crosshead 44 is pivotally mounted on the blocking lever 32. Thus, the crosshead 44 is longitudinally displaceable under the action of the means 6 when the engine body is in an active state, that is to say when it is pivoting.

Finally, the hinged arrangement 40 comprises a rigid pin 45 which is clearly horizontal and forms an acute angle with the longitudinal direction. Seen from above and According to the longitudinal direction from front to back, the pin 45 forms an angle clearly in the order of 5 to 10º with the inner side of the door 3.

The pin 45 is hinged about an elevation axis of the cam 41, as can be clearly seen in Fig. 4.

This pin 45 is also rigidly attached to the crosshead 44. This connects this crosshead 44 and allows the transmission of movements in the longitudinal direction to the cam 41 and by means of the pin 45.

Fig. 5 shows in particular that the rod 31 is firmly connected to the motorization means 6 by means of the locking means 15 and in particular the blocking lever 32.

In Fig. 5, the reference numeral 46 also designates a flexible electrical supply of the motorization means 6.

In view of the above, it is easy to understand that the suspension beam 17 has means for assembling modular elements, by means of which it is possible to adapt the actuating device 11 using selected elements according to the intended door.

With the components of the standard device 11 it is therefore possible to obtain different doors 3 with one or two leaves 4 or even with leaves of different dimensions.

Figures 1 and 2 show a door according to the invention equipped with an actuating device 11 on its upper edge of the frame 5, as mentioned above.

In certain arrangements, the actuating device 11 is arranged at a lower edge of the frame 5.

In Fig. 3, reference numeral 47 designates screws by means of which the plates 18 of the anchoring means 12 are firmly connected to a horizontal plane which is structurally connected to the wall 2.

The screws 47 and the plates 18 allow for easy mounting of the device 11 on the vehicle 1 by simply placing these plates against their support surface, which is firmly connected to the wall 2, and by tightening the screws 47.

It is also clear that it is thus possible to make most or even all of the adjustments of the device 11 and the leaves 4 in the factory before installing the door 3 in the vehicle 1.

The door 3 also comprises connecting means 48 which connect the upper longitudinal edge of a leaf 4 with an opposite, so-called lower edge.

In these figures, the means comprise a rigid elevation pin 49 which is provided with levers 50 provided with rollers (Fig. 3) with grooves each rigidly connected in the longitudinal direction to an edge of the wing to be coupled.

Versions not shown provide for the replacement of the rigid elevation pin 46 in particular by a flexible system.

This system is called flexible because it is clearly deformable, in particular without plastic change, so that its general sheath can be adapted according to a specific profile.

Such a flexible system can be arranged longitudinally, transversely or in elevation according to curvatures, angles and the like.

This allows the precise tracking of the elevation profile longitudinally and transversely of the door and the avoidance of any equipment located in the affected area.

According to the invention, the drive components are integrated in translation, in overlap and for locking on the mobile beam formed by the main element of the suspension telescopic slide rail.

The locking device acts by blocking the main overlapping movement of the suspension telescopic slide rail.

This has the advantages of a modular structure and a structure in a block, which includes the following functions:

- suspension;

- Motorization;

- Drive in translation;

- Drive in overlap; and

- Locking.

We have found that pre-settings are possible in the design of the door 3 and the device 11 in the factory.

Of course, the positioning adjustment of the device 11 with the wings 4 on the vehicle 1 as well as the parallelism of the wings 4 with the posts of the frame 5 nor when installing the door 3 in the vehicle 1.

Such a structure makes it possible to use an identical operating device comprising essentially the same parts over a wide range of frame widths.

The main exception is the suspension beam or the telescopic slide rail and the drive element in translation, here the drive belt 37, the length of which must be adapted to each longitudinal dimension of the frame.

The fastening of the circuit boards 18 on the vehicle 1 is also always identical in certain versions, regardless of the width of the frame 5.

It should be noted that in the examples shown, the overlap does not generate any relative transverse movement between the drive element in translation and the driven element.

This prevents the use of additional mechanical elements aimed at compensating or making such a relative transverse movement acceptable.

The advantages of the invention remain the same for doors with both one and two leaves.

It should also be noted that the operating device 11 for connection to the wing is provided with a locking device fixed to the end element of the suspension telescopic slide rail.

The drive element is connected in translation to this crossbeam (drive belt, screw, etc.).

It therefore represents a larger interface between the actuating device 11 and the wing.

This has the advantage of allowing the removal and installation of the wings 4 without affecting the settings of the door 3.

In the event of an incident, for example the breakage of a pane 51 glued to a frame made of aluminum profile 52, it is not absolutely necessary to take the door 3 out of service for a long time, since the leaf 4 provided with this pane 51 can be replaced very quickly.

This removal/installation operation is also facilitated by the positioning system 25, which allows intervention by a single operator, whereas the known structures required at least two operators to be provided for the installation and removal of a wing.
