EP0876946B1 - Door operator, door with such a device and railway vehicle with at least such a device and/or door - Google Patents

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 doors motorized, in particular for railway vehicles, with at least one leaf capable of being fitted in the bay plan in the closed position, and to slide substantially parallel to the wall where the bay.

More precisely, its objects are a device door operator, a door provided with this device and a railway vehicle equipped with at least one such device and / or door.

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

But doors with one or more leaves, movable following other paths allowing interlocking in the bay, are also in the fields of the invention.

Let us quote documents from the technical field of the invention.

DE-B-2.219.176 describes a stabilizer for sliding door, having runners telescopic articulated on at least one lever swivel, with fixed bearing studs.

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

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

GB-A-2.159.208 describes an assembly door driven by means of a guided belt around deflector rollers.

Document FR-A-2,621,879 describes a sliding-sliding door, with a conjugation bar.

Document US Pat. No. 5,483,769 describes a device sliding-sliding door operator according to the preamble of claim 1.

The known prior art has drawbacks.

For example, document EP-A-400,188 describes a double door in which the operator is transversely fixed relative to the bay. A drive belt is respectively connected to each leaf by a rigidly mounted arm.

This door does not allow movement symmetrical leaves. The settings cannot only be carried out after mounting the leaf on the vehicle. When the leaves are dislodged outside the bay, the belt is deformed transversely

According to GB-A-2.159.208, the belt is made integral with the transverse movements of the leaf by a complex assembly. According to the direction longitudinal, the leaf guide range is limited, which gives it an insufficient hold called guiding flexibility. Here too, the settings cannot only be carried out after mounting the leaf on the vehicle.

The invention aims to solve these drawbacks, in particular.

It aims to obtain an operating device for carries with a reduced number of constituents as well as connections between fixed and mobile parts.

It is thus possible to modulate, from identical constituents, certain characteristics of the door, in particular its longitudinal dimensions.

The device also allows, with a low number of single components, secure blocking of each leaf in closed position.

To this end, one of the objects of the invention is a motorized door operator device, intended for particular to a railway vehicle, with at least one leaf capable of being fitted substantially transversely in a bay in the closed position, and to slide substantially longitudinally along a wall of the vehicle where the bay is located.

This device comprises in combination the characteristics of claim 1.

We understand that the suspension beam is a simple and light rigid component, for example unitary, providing a limited and convenient interface for the mounting of the door on the vehicle on the one hand.

On the other hand, the beam allows to embark the most of the components of the operating device, including the motorization, transmission and guiding means transverse and longitudinal, and therefore the suspension of the leaf.

This avoids transverse deformations of the belts, simplifies the realization of a modular door, while authorizing adjustments to the door prior to its installation, for example in the factory.

Other features of embodiments of the device are exposed.

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

The leaf suspension beam is essentially constituted by a rail means of longitudinal guidance, for example a slide rail telescopic, in a "U" shape with a concavity turned transversely and rigidly fixed with screws or similar to the transverse guide means.

The transverse guide means comprise at at least one slide rigidly fixed to the anchoring means on the one hand and on the other hand to the suspension beam, by example these means include two cylindrical slides transverse, each with an elevation shoulder at a external transverse end.

The transverse guide means comprise a hanging system, allowing positioning longitudinal and / or transverse and / or elevation of the leaf, possibly via guide means longitudinal.

The transverse guide means comprise a transverse stop defining an interior end of the predetermined transverse stroke.

• un bras radial rigidement fixé à une sortie telle que corps ou stator de moteur électrique ;
• une biellette sensiblement longitudinale montée pivotante à distance de la sortie sur le bras radial ; et
• un levier de blocage articulé sur la poutre de suspension.

The articulation assembly at the outlet of the motorization means comprises:

• a radial arm rigidly fixed to an outlet such as the body or stator of an electric motor;
• a substantially longitudinal link pivotally mounted at a distance from the outlet on the radial arm; and
• a locking lever articulated on the suspension beam.

A branch of the lever is pivotally linked to the link opposite the arm, while its other branch includes a light in which is housed a stud secured to the anchoring means and intended to come into locking support against a transverse surface of light.

In this way, the rotation of the outlet and the arm radial causes a transverse displacement of the beam suspension, which is interrupted in a direction of rotation from the exit, by a stop after crossing the bracing of the articulation assembly between the link, the outlet or body and the lever, after a stroke predetermined.

In the opposite direction of rotation, the stroke is limited by the abutment of the guide means transverse against a transverse surface opposite to that light.

• une poulie fixée coaxialement à une sortie telle qu'arbre, des moyens de motorisation ;
• deux poulies d'axe d'élévation, montées sur la poutre de suspension ;
• une courroie à brins sensiblement longitudinaux, en prise avec les poulies et la sortie des moyens de motorisation, un brin au moins étant relié au vantail, par exemple via un mors de pincement ; et
• des galets de tension, dont les axes d'élévation sont montés sensiblement parallèles à celui de la poulie en sortie des moyens de motorisation, de part et d'autre longitudinalement.

The longitudinal transmission means include:

• a pulley fixed coaxially to an outlet such as a shaft, motorization means;
• two elevation axis pulleys, mounted on the suspension beam;
• a belt with substantially longitudinal strands, in engagement with the pulleys and the output of the motorization means, at least one strand being connected to the leaf, for example via a gripping jaw; and
• tension rollers, the elevation axes of which are mounted substantially parallel to that of the pulley at the outlet of the motorization means, on either side longitudinally.

In this way, the rollers and the pulley at the outlet grip and drive a strand of the belt in a state active motorization means.

According to an embodiment intended for door double, an articulated connecting arrangement connects a slide of the transverse guide means, longitudinally at a distance from the locking means, at another slide, so as to cause their transverse, simultaneous and identical displacement.

• une came articulée sur la poutre de suspension autour d'un axe d'élévation, à proximité longitudinalement du coulisseau à distance des moyens de verrouillage ;
• un doigt à lumière inclinée transversalement, solidaire en rotation de la came ;
• un pion rigidement fixé, à distance des moyens de verrouillage, aux moyens d'ancrage et reliant transversalement ces derniers moyens à la lumière du doigt;
• une crosse à proximité de l'autre coulisseau et montée pivotante sur un levier solidaire des moyens de motorisation, de façon à être longitudinalement déplacée sous leur effet ; et
• une tige rigide sensiblement longitudinale, articulée autour d'un axe d'élévation à la came et rigidement fixée à la crosse, afin de les relier lors de ses déplacement longitudinalement.

The articulated leaf connection arrangement includes:

• a cam articulated on the suspension beam around an elevation axis, in the longitudinal vicinity of the slide at a distance from the locking means;
• a light finger inclined transversely, integral in rotation with the cam;
• a pin rigidly fixed, at a distance from the locking means, to the anchoring means and transversely connecting the latter means to the finger lumen;
• a stock near the other slide and pivotally mounted on a lever secured to the motor means, so as to be longitudinally displaced under their effect; and
• a substantially longitudinal rigid rod, articulated around an elevation axis to the cam and rigidly fixed to the stick, in order to connect them during its longitudinal displacement.

According to one embodiment, the stick is integral motorization means via the locking means, and in particular a blocking lever for these means.

The motorization means include a flexible feeding or the like.

The suspension beam has means assembly of modular elements capable of conforming the operating device using selected components, depending on the destination door.

Another object of the invention is a door equipped, for example at an upper edge of its bay, with a operator device mentioned above.

This door is mounted in a wall where is formed the bay, and which are rigidly integral with the anchoring means, for example by screwing.

Let us cite other characteristics of modes of realization of such a door.

The door further comprises means for conjugation connecting a longitudinal edge of the leaf such that upper, at an opposite edge in elevation such as lower, for example these means comprise a rigid rod and / or a flexible system, connected by roller levers with integral longitudinal ramps respectively of a leaf edge.

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

The invention is described in more detail in description which follows, and refers to the attached drawings.

In these drawings, Figure 1 is a view elevation in perspective, from inside door with two leaves in maximum opening position, provided an operating device according to the invention and means of conjugation.

Figure 2 is a view similar to Figure 1, which represents the door according to the invention, in position closed with its doors fitted in the bay.

Figure 3 is a partial sectional view elevation along line III of Figure 2, illustrating the structure of the operator device of an example of production.

Figure 4 is a view in the direction of elevation and from above, of the door of figure 1 in open position.

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

Figure 6 is an elevation view from below, of the door of Figure 1 with its leaves open.

And figure 7 is a view similar to figure 6, with the leaves fitted, that is to say in the closed position.

in the figures, three directions are represented L, E and T codes, which are mutually perpendicular to each other.

The direction L called longitudinal, is considered as substantially horizontal.

The direction T called transverse, is also considered to be substantially horizontal. While the direction E called elevation is considered to be substantially vertical.

Except in the case of local guidelines, the terms "longitudinally" and "transversely" refer in the longitudinal directions L and transverse T.

And the terms "upper" and "lower" are considered along the direction of elevation E, up and down respectively.

While the terms "interior" and "exterior" are considered in the transverse direction T, and are relate in Figure 3, respectively to the right sides and left.

Finally, the terms "front" and "rear" are, except contrary indications, considered according to the direction longitudinal L, respectively left and right on the figure 1.

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

In particular, the case of a door in an external partition of a railway vehicle such as a wagon, generally extended in the longitudinal directions L and elevation E of the vehicle, the latter moving essentially in the longitudinal direction L.

However, the door of the invention can be arranged at various locations in the vehicle, for example at inside the passenger compartment of a vehicle or to close a bulkhead transversely and in elevation.

It goes without saying that the constituents of the invention can take different positions or orientations in space, especially during their operation, manufacturing, transport and storage.

The directions L, E and T are therefore indicative, and given for explanatory purposes only.

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

In order to allow access through the wall 2, this is fitted with a door 3.

As can be seen from the figures, it can be considered that door 3, as well as partition 2, are essentially and generally extended according to longitudinal directions L and elevation E.

However, in direction E, a door along an embodiment not shown of the invention presents some cross-cutting directions.

Door 3 includes uprights, combined here with wall 2 for simplicity, as well as two leaves 4.

The invention also applies to doors 3 provided with a single leaf 4, of course.

The wall 2 is provided with an opening or opening 5, which is essentially or totally released by the leaves 4 in the open or open position of door 3, as in figure 1.

While in the closed (or closed) position, as in figure 2, the leaves 4 of door 3 are inscribed in, and plugging, bay 5.

The outer contour of each leaf 4 is therefore substantially complementary (for example to the game of open / close operation and release) at inside contour of half of bay 5, following longitudinal L, elevation E and transverse directions T.

Each leaf 4 is here substantially rectangular, as seen in the direction T.

The door 3 illustrated is a motorized door, that is to say provided with motorization means 6 for the movement of the leaves 4, with a view to their opening and / or closing.

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

we have seen that door 3 in the figures is a "wandering-sliding" trajectory.

Referring to Figures 4 and 5, we note that in the closed and open positions, the leaves 4 are substantially extended in the longitudinal direction L.

From its open position, each leaf 4 is guided by an arrow F or F ', towards its closed position.

The front edge 7 of a leaf 4 is called the one which is located at the front of the leaf in the direction of movement of closing F or F '.

It is located substantially in the longitudinal center for a double door 3.

Then, leaf 4 follows a trajectory socket in bay 5, close to a displacement of curvilinear translation inwards.

After this interlocking, the leaf 4 is in a plane parallel to the elevation directions E and longitudinal L, between an elevation 8 and a amount of elevation 10 of bay 5, opposite according to the direction L (figure 2).

The leaves 4 are thus inserted in the bay 5, in closing it.

A device 11 called door operator, is provided on door 3 of the rail vehicle 1.

• des moyens d'ancrage 12 destinés au montage de la porte 3 sur la paroi 2 ;
• une poutre 17 de suspension des vantaux 4 ;
• des moyens de guidage linéaire transversal 13 permettant de guider les vantaux 4 à leur emboítement de fermeture et déboítement d'ouverture ;
• des moyens 14 de guidage longitudinal des vantaux 4 ;
• des moyens de motorisation des vantaux 4, sur les figures le moteur électrique 6 ;
• des moyens 15 de verrouillage en rotation prévus pour permettre ou empêcher le déplacement transversal de la poutre de suspension 17 ; et
• des moyens 16 de transmission longitudinale de mouvement aux vantaux 4.

The device 11 comprises in particular:

• anchoring means 12 intended for mounting the door 3 on the wall 2;
• a beam 17 for hanging the leaves 4;
• transverse linear guide means 13 for guiding the leaves 4 at their closing socket and opening disboitement;
• means 14 for longitudinal guidance of the leaves 4;
• means for motorizing the leaves 4, in the figures the electric motor 6;
• means 15 for locking in rotation provided to allow or prevent transverse movement of the suspension beam 17; and
• means 16 for longitudinal transmission of movement to the leaves 4.

Note that the transverse guide means 13, the longitudinal guide means 14, the means of motorization 6, the locking means 15 and the means longitudinal transmission 16 are on board the suspension beam 17. It is itself connected to the vehicle 1 by the anchoring means 12.

In the figures, the anchoring means 12 which are for mounting door 3 on wall 2 include two support plates 18.

These plates are intended to be placed against a horizontal plane, not shown, of the vehicle 1, and rigidly attached to it and therefore to the wall 2 which makes part of the same structural unit as the horizontal plane in question.

Figure 3 shows that the suspension beam 17 consists essentially of a support rail which is part of the longitudinal guide means 14.

This rail, also designated in 17, is part of a telescopic slide connected, via balls 19 as well as longitudinal intermediate rails 20, to the leaves.

Here, the intermediate rails 20 are among of them. Each is connected and supports a leaf 4.

The support rail of the means 17 is in the form of "U" lying with concavity turned transversely towards outside of door 3. In some modes of embodiment, this rail is turned inward.

In some embodiments, the concavity is turned inward, which may limit fouling of the slides.

This support rail is rigidly fixed using screws, not shown, to a shoulder 21 of the means transverse guide 13, visible in FIG. 4.

These, also called means of 13, have a part rigidly fixed to the means anchor 12 on the one hand, and on the other hand another part attached to the suspension beam 17.

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

On the other hand, the slides 22 are here fixed to the suspension beam 17, in order to make them integral in transverse displacement.

In certain embodiments, an articulation, by example with a longitudinal axis, is arranged between the beam 17 and each slide 22.

The slides 22 each include on the Figures a cylindrical bar secured to the beam 17 transversely and slidingly mounted in the housing bar guide, integral with a plate 18. They form a linear, rectilinear and transverse guide.

At an outer transverse end of the device 11, each slide bar is provided with a shoulder 21 as mentioned above for the joining of the beam 17.

Figure 3 shows that the guide means transverse 13 further include a system of positioning 23.

System 23 allows mutual localization precise, along the longitudinal directions and / or transverse and / or elevation, leaves 4 relative to device 11. Here, system 23 is part of a hanging device.

The device 11 is, thanks to the beam of suspension 17, capable of being mounted on vehicle 1 by simple connection of the support plates 18 against parts appropriate vehicle 1.

In fact, the leaves 4 are positioned by through the longitudinal guide means 14 and more precisely of the beam or rail 17 against shoulder 21.

In the illustrated embodiment, the system of positioning provides on the shoulder 21 a groove longitudinal 24 with which a shaped projection cooperates complementary in the longitudinal elevation face inside of beam 17.

Screws, not shown, keep assembled the beam 17 and the shoulder 21 of the means 13.

To also maintain the leaves 4 on the intermediate rails 20, the latter are provided in FIG. 3, hooking means 25.

We also note, in Figure 5 in particular, that a slide bar 22 is provided with its inner free end, and therefore opposite the beam 17 transversely, a transverse stop 26.

The stop 26 defines the inner end of the predetermined transverse stroke of the beam 17.

The motorization means 6 have an outlet 27 (Figures 6 and 7), in fact constituted by an axis elevation.

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

The motor body of the means 6 is connected to a hinge assembly 29.

The articulation assembly 29 is particularly clearly visible in Figures 4 and 5.

Note here that the locking means 15 allow the articulation 29 to be blocked in rotation.

The locking means 15 are suitable in a inactive state to allow transverse movement of predetermined stroke of the suspension beam 17.

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

In FIG. 4 in particular, the whole articulation 29 comprises a radial arm 30, rigidly fixed to the motor body of the means 6.

A link 31 of the assembly 29, shown with a slight inclination from the direction longitudinal L in the figures, is considered to be substantially longitudinal.

The link 31 is pivotally mounted, away from the motor body, on the free end of the radial arm 30.

The articulation assembly 29 also includes a locking lever 32, in particular articulated on the beam suspension 17.

In Figures 4 to 7, it (32) is substantially in triangle shape with one point facing inside.

A branch of the lever 32 is pivotally linked to the link 31 opposite the arm 30.

The other arm of the lever 32 includes a light 33.

Light 33 is made transversely integral anchoring means 12 by means of a stud 34, here provided with rolling means in the light.

In FIG. 7, the orientation of the light is about 20 to 30 ° from the direction longitudinal L, from front left to rear at right of door 3.

The stud 34 secured to the anchoring means 12 is arranged to bear blockages against a surface light 33, where it is housed.

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

This movement is interrupted in a direction of rotation of the motor body by a stop after crossing of the entire bracing 29 between the link 31, the engine body and lever 32.

A security system provides the crossing the bracing point, for closing, when door 3 is to be operated manually, without means assistance 6.

Here the system has a torsion spring mounted on the joint between the rod 31 and the lever blocking 32, so as to urge the other articulation of the rod 31 inward (Figure 5).

In the opposite direction of rotation, the stroke is limited by the abutment of the guide means transverse 13 against the transverse surface or stop 26.

This stop 26 is opposite to the light 33 following the transverse direction T.

Let us now describe the means of transmission longitudinal 16 of movement at the leaves 4.

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

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

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

In FIG. 6, a pulley 35 of these means 16, so-called outlet, is fixed coaxially to the shaft or outlet 27 motorization means 6.

In FIG. 5, we see two pulleys 36, front and rear respectively (left and right), whose elevation axes are mounted on the beam suspension 17.

Reference 37 designates a belt whose strands are substantially longitudinal.

In the figures, it is a belt 37 internally notched to the loop it forms.

The output pulleys 35 and front and rear 36 therefore comprise on an external guide surface teeth complementary to those of the belt 37.

It is clear from Figures 5 and 6 that the belt 37 is engaged with the pulleys 35, 36 and 39.

A longitudinal strand, here inside, is connected to the front leaf 4, while an outer strand is connected to the rear door 4.

FIG. 7 shows pinch jaws 38, arranged at the end of arms fixed on each of the leaves 4.

Each of these jaws encloses an inner strand or outside of the belt 37, so that when moving of these strands, a front leaf 4 is driven forward and a rear leaf 4 is driven towards the rear of the door 3.

Figure 6 also shows tension rollers 39.

These tension rollers 39 are mounted by via elevation axes, at least one of which is adjustable, on the motor support plate 28. The axes of the rollers 39 are therefore parallel to those of outlet 27 and arranged on either side of the pulley 35 supported by this exit.

In other words, the axes of the tension rollers 39 and pulley 35 are substantially aligned along the longitudinal direction L.

This arrangement of the rollers 39 and the pulley exit 35 allows to grip and train the strand inside of belt 37.

The hugging is obtained by an effect of approximation, using adjustment means moving at minus one of the axes of the rollers 39, towards or at a distance from that of the pulley 35. Here, only the axis of the rear roller 39 (figure 5) is adjustable.

This closeness and tightening effect is permanent.

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

In FIGS. 5 and 7, it can be seen that the door 3, which is double, includes an articulated connection arrangement 40.

The arrangement 40 connects the bar of a slide 22, which is longitudinally distant from the means of locking 15, to another slide 22.

The function of this arrangement 40 is to cause the transverse, simultaneous and identical displacement of slide bars 22, and therefore beam 17 and leaves 4.

Figures 5 and 7 show that the arrangement 40 includes a cam 41, pivotally mounted about an axis elevation. The cam 41 is articulated on the beam 17. It is located longitudinally near the slide remote from the locking means 15.

A finger 42 of the arrangement 40 is integral with rotation of the cam 41. It can be seen in FIG. 7 that this finger 42 has a light inclined transversely and longitudinally. In the figure, finger 42 and cam 41 are part of the same room.

With respect to the longitudinal direction L, the orientation of the light of finger 42 as well as that of the light 33, form a triangle with a longitudinal base, one point of which is turned towards the inside of door 3.

This triangle is substantially symmetrical with respect to to the transverse direction T, so that the angles orientation of lights 33 and finger 42 are comparable or even substantially equal.

A pawn 43 is also part of the arrangement 40. The pin 43 is rigidly fixed to the anchoring means 12, remote from the locking means 15.

It transversely connects the light of finger 42 and the means 12. Thus, when the finger 42 is driven in rotation about the axis common to the cam 41, the pin 43 acts as a fixed point and causes the displacement of the beam 17 in the direction T.

A stock 44 of the arrangement 40 is arranged at proximity to the other slide 22. In a plane horizontal, as in figure 5, the stick has a inwardly-shaped crescent-shaped crescent door 3. The concavity of the crescent surrounds the means 6.

The butt 44 is pivotally mounted on the lever blocking 32. Thus, the butt 44 is longitudinally moved under the effect of the means 6, when the body of engine is in an active state, i.e. when rotates.

The articulated arrangement 40 finally comprises a rod rigid 45, substantially horizontal and forming an angle weak with longitudinal direction. View from above and from front to rear in the longitudinal direction, the rod 45 forms an angle substantially of the order of 5 to 10 ° towards the inside of door 3.

The rod 45 is articulated around an axis elevation to cam 41, as is clear from the figure 4.

This rod 45 is also rigidly fixed to the butt 44. This connects this butt 44 and allows the transmission from the latter of the movements longitudinal towards cam 41 and through the rod 45.

Figure 5 shows in particular that the link 31 is integral with motorization means 6 by through the locking means 15, and particular of the locking lever 32.

Also in FIG. 5, the reference 46 designates flexible power supply of the means of motorization 6.

It is well understood, in view of the above, that the suspension beam 17 has assembly means modular elements, thanks to which it is possible to conform the operating device 11 using elements chosen, depending on the destination door.

With components of the standard device 11, it is therefore possible to obtain different doors 3 with one or several leaves 4, or with various dimensions leaf.

Figures 1 and 2 show a door according to the invention, equipped at its upper edge with opening 5, with a operating device 11 as mentioned above.

In some arrangements, the operating device 11 is arranged at a lower edge of the opening 5.

In FIG. 3, the reference 47 designates screws through which the plates 18 means anchor 12 are made integral with a horizontal plane which is structurally linked to the wall 2.

The screws 47 and the plates 18 allow a easy mounting of the device 11 on the vehicle 1, simply by placing these plates in abutment against their receiving surface integral with wall 2 and in tightening the screws 47.

We also understand that it is thus possible make most, if not all, of the settings device 11 and leaves 4 at the factory, prior to mounting door 3 on vehicle 1.

The door 3 also includes means for conjugation 48 which connect the upper longitudinal edge a leaf 4 at an opposite edge in elevation called edge inferior.

In these figures, the means comprise a rod elevation rigid 49, connected by levers 50 provided with rollers (figure 3) to longitudinal gutters secured respectively to an edge of the leaf to be combined.

Embodiments not shown provide to replace in particular the rigid elevation rod 49 with a flexible system.

This system is said to be flexible because it is substantially deformable without plastic alteration in particular, so to be able to conform its general envelope following a determined profile.

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

This allows you to follow the profile as closely as possible longitudinal elevation and transverse of the door and bypass any equipment located in the area concerned.

According to the invention, the drive components translation, swaying and locking are on board the mobile beam formed by the element main telescopic suspension rail.

The locking device works by blocking the main sway movement of the slide telescopic suspension.

• suspension ;
• motorisation ;
• entraínement en translation ;
• entraínement en louvoiement ; et
• verrouillage.

This has the advantages of a modular, monobloc structure which integrates the functions of:

• suspension;
• motorization;
• translational training;
• sway training; and
• locking.

We have seen that presetting was possible during of the factory construction of door 3 and the device 11.

Of course, the positioning adjustment of the device 11 with the leaves 4 on the vehicle 1, as well that of the leaves 4 parallelism with the amounts of the bay 5, remains to be carried out when mounting door 3 on the vehicle 1.

With such a structure, for a large range of bay widths, one can use a device identical operator and comprising essentially the same rooms.

The main exception is the suspension beam or telescopic slide as well as the element drive in translation, here the belt 37, the length must be adapted to each longitudinal dimension bay.

The fixing of the plates 18 on the vehicle 1 is also always the same, in certain modes of realization, whatever the width of the opening 5.

Note that swaying does not cause, in illustrated examples of transverse relative movement between the drive element in translation and the element causes.

This avoids the use of mechanical elements to compensate or make acceptable such a transverse relative movement.

The invention retains its advantages both for a door with one or two leaves.

Note further that the operating device 11 is fitted with a hanging device fixed to the end element of the telescopic suspension rail, for the connection with the leaf.

This element is connected to this crosspiece drive in translation (belt, screw, etc.).

It therefore provides a major interface between the operator device 11 and the leaf.

This has the advantage of allowing disassembly and an assembly of the leaves 4, without affecting the settings of the door 3.

In the event of an incident, for example, the rupture of a window 51 glued to an aluminum profile frame 52, it it is not imperative to immobilize door 3 for a long time, since the leaf 4 provided with this window 51, can be exchanged very quickly.

This assembly / disassembly operation also facilitated by the positioning system 25 which allows intervention by a single operator while the known structures required at least two operators for the assembly or disassembly of a leaf.
