Description

Title of the invention: MULTIFUNCTIONAL MODULE WITH IMPROVED ROBUSTNESS FOR A SLIDING SWING DOOR, AND VEHICLE THUS EQUIPPED Technical field of the invention

[0001] The present invention relates to the field of sliding swing doors for transport vehicles, in particular of the train, tram or trolleybus type. The invention relates more specifically to a module, intended to equip such doors, which is capable of fulfilling different functions linked to the implementation of these doors, in particular in the event of an emergency. The invention relates in particular to such a module, the mechanical integrity of which can be preserved whatever the operational conditions it is likely to encounter. State of the art

[0002] It is known to equip transport vehicles with sliding swing doors whose movement has an opening phase, in which the translational movement of the leaves along their suspension, in the opening direction, is combined with an overall movement of the suspension of the leaves, in the lateral direction towards the outside of the vehicle. Then, when the lateral position is reached, the leaves continue to move longitudinally until they reach the desired opening. This movement, carried out in the opposite direction to close the door, makes it possible in particular to ensure perfect sealing when the door is closed.

[0003] In the state of the art, it is planned to equip these sliding swing doors with mechanical devices, making it possible to ensure various functionalities in the event of an emergency.

[0004] First of all, these doors are equipped with a device allowing an emergency opening function. In other words, the actuation of this device controls the forced opening of the door, in particular in the event of a perceived danger by the users. For this purpose, a solution is known using an unlocking cable, capable of being activated by a user using an emergency handle. This cable then drives a finger, capable of unlocking the previously engaged locking mechanism.

[0005] Furthermore, these sliding swing doors are also provided with a device ensuring their locking, in particular in the event of malfunction of the mechanical means normally dedicated to this purpose. Under these conditions, any movement of the door, from its closed position to its open position, is prevented. This type of device can conventionally use an actuating member, in generally placed in the door leaf, which prevents the swaying movement thanks to a bolt inserted in a strike plate, itself fixed to the body of the vehicle.

[0006] In the prior art, these two devices, respectively ensuring emergency opening and locking, are usually independent. Solutions are certainly known, in which these devices are installed in close proximity to each other. In any case, their implementation is dissociated, namely that no mechanical element, involved in the performance of one of these functions, intervenes in the performance of the other of these functions.

[0007] In order to improve this state of the art, the applicant proposed, in FR-3 061 227, a so-called multifunctional module capable of fulfilling both a function of locking the door and an additional function of emergency opening of this same door. Structurally, this module comprises a shaft, formed of an axle and a hub, each of which is respectively dedicated to the implementation of one of the above functions. Thus, the rotation of the hub allows in particular an emergency opening of the door, while the rotation of the axle allows in particular a locking of this door.

[0008] This solution has proven satisfactory, in that it provides numerous advantages over the prior art presented above. Given that these two shaft elements are arranged in close spatial proximity, this gives a very satisfactory compactness to the module according to FR-3 061 227. Furthermore, the implementation of this module is particularly simple for the user. Finally, this module is capable of fulfilling additional functions, apart from the aforementioned emergency opening and locking.

[0009] The mechanical solution, presented in FR-3 061 227, is however accompanied by specific drawbacks in certain operational conditions. In this case, the integrity of the sliding swing door equipped with this multifunctional module is then not completely preserved. Indeed this door is likely to undergo deformations or even mechanical breakages, which can cause substantial repair costs as well as untimely shutdowns in the operation of the equipment.

[0010] In view of the above, an objective of the present invention is to produce a module which, while ensuring the same basic functions as that described in FR 3 061 227, provides improved robustness of the door compared to this prior module.

[0039] The attached figures illustrate a module I intended to equip a sliding swing door, for example of the type described in FR-3 003 887 and, more briefly, in FR-3 061 227. This door, which is shown in a very simplified manner in [Fig.l], is intended to equip a transport vehicle, such as in particular a tram, a trolleybus, or even a train. This door is known as such, so that it will not be described in detail in the following.

[0040] It is composed in particular of at least one leaf, in this case two leaves 200 in the example shown, as well as a mechanism allowing the movement of each leaf. Such a mechanism comprises in particular a fixed beam 300 secured to the frame, as well as a movable beam 400 secured to the suspension of the leaves 200. This movable beam 400 is capable of swaying relative to the fixed door, according to the double arrow F400 in [Fig.l], thanks to motor means not shown. In all the figures, the letters Int and Ext designate respectively the interior and the exterior of the vehicle. We will now describe in more detail the module I, in accordance with the invention. In what follows, we will refer to the module in accordance with the teaching of FR-3 061 227, emphasizing in particular the structural and functional differences between the module I of the invention and this prior module.

[0041] With reference in particular to Figures 2 and 3, the module I according to the invention firstly comprises a casing, designated as a whole by the reference 1. This casing has an elongated body 10, forming a web, the main dimension of which extends transversely relative to the vehicle. This main dimension defines the main axis A1 of the module, which will be noted to be generally perpendicular to the main direction of the vehicle, corresponding to the forward movement of the latter. Two flanges 12 and 13, mutually perpendicular, extend downwards from the lower face of the veil 10, facing the interior of the vehicle. These flanges are called respectively interior 12 and exterior 13. The casing 1 further comprises a plate 11, on which the veil 10 is fixed, preferably in a removable manner. This plate 11 extends from a foot 110, itself secured to the fixed beam 300.

[0042] The characteristics listed in the preceding paragraph are common to both module I of the invention and the module conforming to the teaching of FR-3 061 227. On the other hand, module I differs from the prior art in that the outer flange 13 is extended by a region 14 extending horizontally in the direction of the axle described below (see and, more particularly, [Fig. 4]). This region 14 is terminated by a rim 15, projecting upwards and therefore being substantially parallel to the flange 13. This rim 15 is hollowed out with a through orifice, so as to provide a bearing function for a pin 17. In service, this pin is capable of rotating relative to the bearing 15, along the axis A17.

[0043] On the side of the rim 15 facing the flange 13, the pin 17 has a head 18 of larger diameter, allowing the retention of a spring 7 interposed between this head and this rim. On the side of the rim opposite the flange, the pin 17 is secured to a lever 4, both in rotation and in translation. For this purpose, a key 19 penetrates into a diametrical hole of this pin, it being understood that any other equivalent means could be provided.

[0044] As shown in particular in Figures 4 and 5, the lever 4 comprises an elongated main blade 40, terminated by an end 4L. As will be detailed below, the latter forms a locking wedge, intended to cooperate with a pulley equipping the module according to the invention. Opposite the end 41, the blade 40 is extended by an actuating tab 42, the function of which will be described below. Given that the lever 4 is integral with the pin 17, it is also free to rotate relative to the bearing 15 around an axis denoted A4, which coincides with that A17 mentioned above. The wedge 41 and the tab 42 are arranged on either side of the axis of rotation so that, as will be seen below, the lever can adopt a rocking movement.

[0045] The spring 7 comprises a winding 70, which surrounds the region of the pin 17 between the rim 15 and the head 18. A first end 71 of this spring enters a notch 140 made in the area 14, while its opposite end 72 enters a notch 44 made in the lever 4. As will be seen in the following, this spring 7 is capable of returning the lever to its so-called free rotation position 4.

[0046] Just like the prior module in accordance with FR-3 061 227, the module of the invention I further comprises a main shaft formed of two shaft elements, namely a solid central axle 2 visible among others in Figures 2 and 3, as well as a peri hub spherical 3 more particularly visible in figures 5 and 9. This axle, integral in translation with the flange 12 and the foot 110, has a single degree of freedom in rotation relative to this flange 12 and this foot 110, around its main axis A2 parallel to Al.

[0047] The hub 3, which is mounted around the part of the axle 2 adjacent to the flange 12, is integral with the axle in translation in two opposite directions. For this purpose, the flange 102 blocks the first end of the hub in a first direction, while radial fingers 21 and 21' equipping the axle block the second end of this hub in the other direction. This hub has a single degree of freedom in rotation relative to the axle, around their common main axis. The hub 3 is also surrounded by the winding 76 of a spring 75, a first end 77 of which is integral with the casing 1, and the other end 78 of which is integral with the pulley 50.

[0048] The axle 2 of the module according to the invention is further equipped with a so-called deactivation cam 22 (see in particular figures 4, 5, 8 and 9), which constitutes a distinctive part compared to the prior module according to FR-3 061 227. This cam, which is placed between the foot 110 and the fingers 21 21', is secured by any appropriate means to the axle 2. It comprises a ring section 23 of constant section, forming a thinned portion, as well as an eccentric 24 of larger section, forming a swollen portion. As will be described below, this cam is capable of pivoting the lever 4 around its axis A4.

[0049] The first end of the hub, adjacent to the inner flange 12, supports several pulleys 50, 51 and 60. In the example illustrated, these three pulleys are integral with each other, while also being integral with the hub 3. There are first of all two control pulleys 50 and 51, called driving pulleys, each of which is integral with a respective cable 52 and 53, both shown schematically. These cables are each connected to control members not shown, such as handles, provided respectively on the inner side and the outer side of the door. Furthermore, there is a transmission pulley 60, called driven, which is integral with an additional cable 61 shown schematically. The latter is capable of cooperating with a device not shown, of a type known per se, making it possible to unlock the door.

[0050] A distinctive characteristic of the control pulley 50, with respect to the prior art embodied by FR-3 061 227, is more particularly visible in [Fig.7]. This pulley 50 is in fact hollowed out with a notch 55, allowing the reception of the locking wedge 41 of the lever 4. In the example illustrated only the pulley 50, adjacent to this lever, is provided with such a notch. As a variant, it is possible to provide that at least one other pulley, such as for example that 51, has a similar notch allowing the reception of the aforementioned locking wedge.

[0051] Reference will now be made to different elements belonging to module I, which are similar in their structure and function to those in accordance with the teaching of FR-3 061 227. These different elements, which are not the subject of the present invention, will therefore be described succinctly.

[0052] At its inner end, facing the flange 12, the axle 2 is fixed to a handle 8, allowing it to be rotated by a user present in the vehicle. At its opposite outer end, facing the flange 13, the axle 2 is also fixed to a rotating part 9 which has two bulged regions 91 and 92, generally diametrically opposite one another. The first region 91 supports a stop element 90 (see in particular [Fig. 8]), which extends towards the interior of the vehicle, substantially along the axis A2. Furthermore, the opposite region 92 of this rotating part 9 is hollowed out with two indexing orifices 93 and 94 (see Figures 3 and 8).

[0053] Various additional functional parts also equip the module casing. First of all, there is a pusher 211 of a type known per se (see [Fig. 3]), which is mounted on the casing. This pusher is equipped with a spring capable of pushing a ball towards the rotating part 9, namely towards the outside of the vehicle. The location of this ball, which is not shown, is shown by the dotted lines 212 on this same [Fig. 3].

[0054] The implementation of the module according to the invention, as described above, will now be explained in the following. This explanation will in particular highlight, on the one hand, the steps which are common to the present invention and to the teaching of FR-3 061 227, and on the other hand, the steps which are distinctive of the present invention.

[0055] In normal service of the vehicle, the module I according to the present invention is in a functional configuration identical to that of the module conforming to FR-3 061 227. In particular, the spring 75 returns the pulleys 50, 51 and 60 to their rest position. No other significant mechanical action is exerted on the two shaft elements 2 and 3, which are generally immobile. Consequently, the latter do not interfere with the overall operation of the door, just like the various mechanical parts associated with them. The movable beam 400 is free to move relative to the fixed beam 300, so that the free opening of the door is not hindered. It will be noted that, during this normal service, the lever 4 is distant from the pulley 50, so that it does not cooperate with the notch 55 formed in the latter.

[0056] It is first assumed that an emergency opening of the door, equipped with module I according to the invention, is to be carried out. Such an emergency opening is implemented in the same way as for the prior module, described in FR-3 061 227. Thus, a user operates the handle associated with one of the control pulleys 50 and 51, which induces a translational movement of the cable 41 or 51. The three pulleys 50, 51 and 60 are then rotated correspondingly, which causes the translational movement of the cable 61 associated with the pulley 60. Under these conditions, the door can be unlocked.

[0057] It will first be noted that, during the rotation of these pulleys, the hub 3 is also driven in rotation. During this movement of the pulleys and the hub, the central axle 2 remains fixed, namely that the hub 3 rotates freely around this axle. It will also be noted that, during the step described in the previous paragraph, the lever 4 does not interfere with the pulley 50, namely that it occupies its so-called inactive position or position of free rotation of this pulley. This free rotation is materialized by the double arrow F50, visible in [Fig.5].

[0058] It is now assumed that the door is to be locked due to a malfunction. This situation typically occurs when the vehicle's control system does not provide clear information that the door is closed and locked. In this case, as in the teaching of FR-3 061 227, a member of the on-board staff operates the control handle 8, which causes the axle 2 and the rotating part 9 to rotate accordingly according to the arrows F2 and F9 in [Fig.8].

[0059] During the initial phase of the movement of the rotating part 9, the ball 212 of the pusher 211 is released from the first orifice 94, provided in this part 9. Then, at the end of the rotational movement of the latter, the second orifice 93 comes opposite the pusher 211. The spring, equipping the latter, then pushes the ball 212 back into the housing, defined by this orifice 93. The rotating part 9 is consequently held in place, that is to say indexed in this active position, which is shown in particular in [Fig.7]. Consequently, the movable beam 400 cannot move outwards relative to the fixed beam 300, so that any attempt to open the door is prevented.

[0060] Figures 8 and 9 also illustrate an essential characteristic of the invention, which distinguishes module I from that which is the subject of FR-3 061 227. When the axle 2 is rotated according to the arrow F2 as indicated above, the cam 22 also pivots around the main axis of this axle according to the arrow F22 visible in [Fig. 9]. Under these conditions, the eccentric 24 of this cam now comes into contact with the lug 42 of the lever, which contributes to moving the latter in translation according to the arrow F42 shown in this same [Fig. 9]. It will be noted that this movement takes place against the spring 7, which contributes to pressing the lug 42 against the eccentric 24.

[0061] Under the effect of the movement of the tab 42, the lever 4 is subjected to a rocking movement around its axis A4, according to the arrow F4 in [Fig.9]. Under these conditions, the wedge 41 enters the notch 55, according to the arrow F41 in the same [Fig.9]. The lever 4 is now in its so-called active position, allowing the locking of pulley 50 and, consequently, of the set of pulleys 50, 51 and 60. This locking is shown by the crossed-out double arrow F'50 in [Fig.9], which must be compared with the arrow F50 representing the free rotation of the pulleys in [Fig.5].

[0062] If we now assume that a member of the flight crew deactivates the door locking, he operates the handle 8 in a direction of rotation opposite to that of the arrow F8. Under these conditions, the axle and consequently the cam 22 are rotated in directions opposite to those of the arrows F2 and F22. The eccentric 24 withdraws from the lug 42, which is now in contact with the thinned portion 23. In this way the spring 7 returns this lug upwards, in the opposite direction to the arrow F42. This leads to the pivoting of the lever 4 in the clockwise direction, opposite to the arrow F4. The wedge 41 then disengages from the notch 55, so that the device is again in its configuration of free rotation of the pulleys, as visible in [Fig.5].

[0063] The invention makes it possible to achieve the objectives mentioned above.

[0064] It will first be noted that it is to the applicant's credit to have identified the drawbacks linked to the teaching of FR-3 061 227. Thus, when the multifunctional module, in accordance with this document, is in an active locking configuration, the emergency opening means with which it is equipped can still be activated. In other words, this active locking configuration can in theory be accompanied by an active emergency opening configuration. In practice, when the prior module ensures the locking of the door, a user remains able to activate the emergency unlocking: the door can therefore be unlocked while being effectively locked.

[0065] In this exceptional and unlikely operational situation, the mechanical connections of the leaves are reduced due to the absence of locking. This lack of total mechanical retention of the leaves can be detrimental in certain occurrences, for example if the transport vehicle in question crosses another vehicle traveling at high speed, or if passengers exert a high force on the inside of the leaf of this vehicle. High loads are then generated, which are likely to mechanically damage the door. This type of situation is all the more untimely in the case of a door whose mechanical integrity is not originally impaired, but which is blocked solely due to an electronic / computer fault.

[0066] In order to overcome this drawback, the invention provides so-called deactivation means, which make emergency opening impossible in an activated locking configuration of the door. In the example illustrated, these deactivation means comprise the lever 4 and its locking wedge 41, the cam 22 allowing this lever to be mobilized, as well as the notch 55 for receiving the wedge 4L. As seen above, when the door is locked, the deactivation means are activated so as to prevent rotation of the set of pulleys. Consequently, any untimely emergency opening is avoided, thereby maintaining the mechanical integrity of the entire door for the duration of the locked state.
