Abstract

The closure catch for a motor vehicle bodywork catch has hooks (46) connected to the frame and others (56) attached to the tailgate (2) and a lock (60). The hooks engage when the hatch moves from an open to a closed position, to allow mutual engagement of the hooks. The locks are actuated to cause a relative movement of the hooks to a point where the hatch is pressed firmly against the frame.

Description

The present invention generally relates to devices designed to shut off an opening which is formed in the body of a motor vehicle and which provides access to the interior of the latter.

More specifically, the invention relates to a closure device for a motor vehicle access opening, mainly comprising a frame bordering the opening and a leaf selectively applied to the frame to close the opening, dispositi in which the frame has a mounting edge, releasable edge opposite the mounting edge, and two guiding edges connecting the releasable edge to the mounting edge, and wherein the leaf has a bound edge, secured to the edge mounting by a connecting hinge, edge guided opposite the bound edge and selectively applied to the releasable edge of the frame, and two free edges connecting the guided edge to the bound edge and selectively applied to the respective guide edges of the frame, the leaf consisting essentially of two panels, the first of which provides at the leaf its bound edge and the second its guided edge, and these two panels being articulated one on the other by common edges re specimens by means of a hinge internal to the leaf, arranged between the edges bound guided.

For example, patent document FR 2 658 discloses devices of this type, generally intended for lateral openings, an example of which is illustrated in FIG.

leaf 2 of such a device comprises, as it is said above, two panels 21 and 22 occupying in this case positions respectively upper and lower, and used to close an opening O.

This opening is bordered by a frame 1, whose upper horizontal edge 11, said mounting edge 11, and the lower horizontal edge 13, said releasable edge, are located in Figure 1, and whose raised edges 12 and 14, said guide edges, are visible only in the figures illustrating the invention, for example Figure 4. The linked edge 201 of the leaf 2, which belongs to the upper panel 21, is connected to the mounting edge 11 of the frame by means of a articulation or hinge 3 and the panels 21 and 22 are connected to each other, their respective common edges 210 and 220, by means of other hinge or hinge 30.

The guided edge 203 of the leaf 2, which belongs to the lower panel 22, is connected by a guide joint 32 to a guide carriage 82 (visible in FIG. 3 for example) which circulates and rests on a rail 81 fixed to the frame and disposed on one of the two guide edges 12, 14 of the frame 1.

Thanks to this arrangement, known in itself from the patent document FR-2 731 658, the leaf 2 can fold into the wallet to the mounting edge 11, as shown schematically in Figures 3, thus releasing the opening O from the releasable edge 13 of the frame, while in the closed position of the leaf, the free edges 202 and 204 of the latter are applied to the guide edges 12 and 14 of the frame 1.

In the arrangement which offers the best accessibility to the opening O by folding leaf 2, the latter extends at least partially on two adjacent sides of the vehicle, so that three joints 31, 30 and 32 are arranged as illustrated on Figure 1.

In the closed position of the leaf 2, these joints are thus at the apices of a triangle high height and have a misalignment "d" sensitive, which, under 'action of closing forces F, induces a relatively high pressure force P.

if effort is large enough, can alone ensure the compression of the seal which borders the frame 1, and can then ensure satisfactory stability of the leaf in the closed position.

When on the other hand the leaf 2 extends more on a vehicle side, as is often the case for rear openings of breaks or small utilities, and as' illustrate Figures 2 and 3 in full lines, the three joints 31, 30 and 32 of the leaf are substantially aligned in the closed position of the latter.

Under these conditions, the pressure force P1 may be insufficient to ensure good compression of the seal and to resist a possible traction force opposite the force P1, whether this force is due to a manual action, or it is due to the aerodynamic actions of depression induced by the speed of movement of the vehicle.

In this context, the object of the present invention is to provide an articulated shutter device of the type previously described which, even in the case where the leaf covers at most one side of the vehicle and where the joints correlatively have a low misalignment, offers adequate support of the leaf on the frame and ensures a locking of the leaf during the entire period when it must remain closed.

To this end, the device of the invention, furthermore in conformity with the generic definition, gives the above-mentioned preamble, is essentially characterized in that it furthermore comprises at least first attachment means connected to the frame, second hooking means connected to the blade, and locking means the first and second fastening means adopting, when the leaf passes an open position to a closed position, a crossed crossing position allowing their mutual engagement, and that the locking means are selectively controlled to cause relative movement of the first and second hooking means from their overtaking position overtaken to a latching position under stress, for which the leaf is firmly applied to the frame.

Preferably, the hooking means and the locking means are arranged closer to the common edges of the panels than to each of the bound and guided edges of the leaf, and the device advantageously comprises first hooking means on each guide edge of the leaf. frame and corresponding second fastening means on each free edge of the leaf.

According to a first possible embodiment of the invention, the locking means are for example arranged on the leaf.

In a first variant of this first embodiment, the locking means are arranged on the leaf, between the free edges of the latter, while second attachment means are movably mounted on the leaf, and the locking means are connected to the second attachment means by a linkage.

According to a second variant of this first embodiment, locking means are provided on each free edge of the leaf to respectively move the second corresponding latching means, which are mounted movably on the leaf.

According to a second possible embodiment of the invention, the locking means are for example provided on each guide edge of the frame to respectively move the corresponding first attachment means, which are mounted movably on the frame.

In all cases, the locking means may comprise one or more eccentrics.

The attachment means may themselves take various forms, the first and second attachment means being for example generally consisting, at least, of a bolt and a strike hook, or a rocking lever and a lug providing support for the tilting lever.

To ensure ideal retention of the leaf, it may be useful to ensure that the attachment means are linked to the locking means by a mechanical connection which, at least for the closing position of the leaf, allows a transmission of movement that locking means to the attachment means, and which therefore prevents a transmission of movement in the opposite direction.

For this purpose, in particular, the locking means may comprise one or more pawls, and / or one or more speed reducers providing a one-way motion transmission.

The guided edge of the leaf is preferably at least guided by a rail along a corresponding guide edge of the frame, and possibly by two rails arranged along the respective guide edges of the frame.

The device of the invention may further comprise a locking finger disposed on the guided edge of the leaf a guide support integral with the releasable edge of the locking finger frame and the guide support cooperating in the closing position of the leaf, to solicit this leaf against the frame.

To facilitate actuation of the leaf, the device of the invention may comprise at least a first end-of-travel detector capable of detecting an intermediate position of the leaf, located between the open and closed positions and for which the first and second hooking means are in their crossed crossing position, the locking means comprising at least a first electric motor, and first electric motor being controlled at least the first end-of-travel detector. As shown in FIG. 2, the invention is particularly useful in the case where the frame extends at most on one side of the vehicle.

As already explained above with reference to FIGS. 1 to 3 which illustrate the context of the invention, the latter generally relates to a device for closing off an access opening O of a motor vehicle, and which mainly comprises a frame 1 bordering 'opening and a leaf 2 applied at will on the frame 1 to close the opening O.

The frame 1 has (FIGS. 1 and 3 a mounting edge 11, a releasable edge 13 opposite to the mounting edge 11, and (FIG. 4) two guiding edges 12 and 14 connecting the releasable edge 13 to the mounting edge 11.

The leaf 2 has (FIG. 3) a bound edge 201, secured to the mounting edge 11 by an articulation hinge or hinge 31, a guided edge 2 opposite the bonded edge 201 and applied at will on the releasable edge of the frame 1, and (Figure 4) two fiber edges, 202 and connecting the guided edge 203 to the edge 201 and applied at will on the respective guide edges and 14 of the frame 1.

This leaf 2 consists essentially of two panels, 21 and 22, the first 21 of which provides the leaf with its bound edge 201 and the second 22 with its guided edge 203, these two panels 21 and 22 being articulated to one another by their respective common edges, 210 and 220 (Figure 3), by means of a hinge or hinge 30, internal to the leaf and disposed between the bonded edge 201 and the guided edge 203. As shown in Figure 3, the guided edge 203 of the leaf 2, which belongs to the second panel 22, is connected by a guide hinge 32 to a guide carriage 82 which circulates and leans on a rail 81 fixed on one of the two guide edges 12 or 14 of the frame 1.

In the case where the leaf has a significant weight, it may be advisable to provide a guide carriage 82 and a rail 81 on each side of the guided edge of the leaf 2, one of the rails being disposed on the guide edge 12 of the frame 1, and the other rail being disposed on the guide edge 14.

Limit switches, such as 91 92 Figure 3), are arranged along at least one of the rails 81 to detect the extreme positions of the corresponding guide carriage 82, that is to say the positions' opening and closing the leaf 2.

In general, the device of the invention comprises hooking means connected to the frame and generically designated by the reference 4, hooking means connected to the blade 2 and generically designated by the reference 5, and locking means 6 for to make the catching means 4 and 5 cooperate.

To do this, the invention provides on the one hand that attachment means 4 and 5 adopt, when the leaf 2 passes from its open position to its closed position, a crossed crossing position allowing their mutual engagement, and on the other hand, the locking means 6 can be controlled to cause relative movement of the hooking means 4 and 5, from their crossed crossing position, to a latching position under stress for which the leaf 2 is firmly applied on the frame 1.

FIGS. 4 to 6 illustrate the general principle of the invention by a device according to a first embodiment of the invention, according to which the locking means 6 are carried by the leaf 2, and more precisely according to a first variant of this invention. first mode, according to which the locking means 6 are centralized and arranged halfway between the free edges 202 and 204 of the leaf 2.

In addition, the first variant of the first embodiment of the invention illustrated in Figures 4 to 6 corresponds to the case where the locking means 6 are manually operable.

For example, these locking means 6 comprise a turntable 60 capable of being rotated about an axis 600 by means of a handle 602 shaped as a lever and accessible from outside the vehicle, the axis of rotation 600 being fixed to the leaf 2 by means of a support 601, and the plate 60 carrying two eccentric 61d and 61g.

These eccentrics 61d and 61g occupy diametrically opposed positions on the turntable 60 and are intended to control the right and left coupling means 5, to which they are connected by a linkage formed of respective connecting rods 71d and 71g.

The attachment means 5, mounted movably on the free edges 202 and 204 of the leaf 2, consist for example of two rocking levers 51d and 51g, each of which is articulated on a fixed support wing 2, such as 510d and 510g, and on the corresponding rod 71d and 71g.

The attachment means 4 carried by the frame 1 consist, for example, of tabs 40d and 40g disposed on the respective guide edges 12 and 14 of the frame 1.

In this case, as in the general case, the attachment means 4 and 5, as well as the locking means 6, are preferably arranged as close as possible to the hinge 30, that is to say closer common edges 210 and 220 of the panels 21 and 22, the connected edge 201 of the leaf 2, and the guided edge 203 of this leaf. Nevertheless, the attachment means 4, 5 and the locking means 6 can be mounted on the lower panel 22, generally without glazing, that is to say closer to the guided edge 203 of the leaf than the edge. '201.

Elastic buffers, such as 511d and 511g and fitted for example with tilting levers 51d and 51g, are advantageously provided for damping vibrations and exerting, by elastic compression, a pressure between the attachment means 4 and 5.

In Figure 4, the handle 602 is placed in a position that prevents interference between the attachment means 4 and 5, that is to say between the tabs 40d, 40g, and the corresponding swing levers 51d and 51g.

If the leaf, in the position illustrated in FIG. 4, is being closed, it can therefore move from this position, in which the rocking levers 51d and 51g are opposite the external faces of the corresponding tabs 40d and 40g, at a position (Not shown), in which the tilting levers 51d and 51g and the tabs 40d and 40g corresponding cross, and into a position, said crossing crossed, in which the rocking levers 51d and 51g are facing the inner faces of the legs 40d and 40g corresponding.

Once reaching the crossover position exceeded, the handle 602 can be actuated, as shown in Figure 5, to rock the tilting levers 51d and 51g, through the rods 71d and 71g.

The tilting levers 51d and 51g then come to rest, via the buffers 511d and 511g, on the internal faces of the tabs 40d and thus develop a force P2 that helps the closing of the leaf 2 on the frame 1, and the compression of the seal J by the leaf. Figure 6 shows the leaf 2 in the closed and locked position, the handle 602 being completely inclined in a position of maximum separation of the rods 71d and 71g and pivoting of the rocking levers 51d and 51g.

In this position, the eccentric 61d is shifted towards the outside of the vehicle relative to the line joining the axis of rotation 600 of the plate 60 to the pivot axis 500d of the rocking lever 51d, as is the eccentric 61g is offset towards the outside of the vehicle relative to the straight line joining the axis of rotation 600 of the plate 60 to the pivot axis 500g of the rocking lever 51g, so that the restoring forces exerted by the compressed pads 511d and 511g not only have the effect of soliciting the hooking means 4, 5 and locking 6 to their open position, but even have the effect of confirming them in their locking position.

Thanks to this configuration, known in mechanics under the name of "kneepad" or "dead-end configuration exceeded", the leaf 2 can remain indefinitely in its closed position and locking without any input of energy.

FIGS. 7 to 9 show another device, also in accordance with the first embodiment of the invention, according to which the locking means 6 are carried by the leaf 2, and even also in accordance with the first variant of this first embodiment, according to which the locking means 6 are centralized and arranged midway between the free edges 202 and 204 of the leaf 2, this other device being distinguished from that of Figures 4 to 6 in that the locking means 6 are operable at means of a geared motor comprising an electric motor 62 and a speed reducer 620, providing a one-way motion transmission. Although the motorization of the device of invention allows to facilitate their operation, basic precautions must be taken to avoid malfunctions.

Indeed, since it is a priori preferable to provide hooking means 4 and 5 on each of the free edges 202 and 204 of the leaf 2, their maneuvers must be synchronized, either by means of a single centralized motorization, or by the use synchronized geared motors.

The device which is illustrated in FIGS. 9 and comprises a centralized motorization, presents on this plane a particularly favorable arrangement since such an arrangement ensures, by construction itself, the perfect synchronization of the gripping means 4 and 5 on each side 202 and 204 of the leaf.

However, this arrangement requires the geared motor 62, 620 on the leaf 2, which involves bringing the electric current by flexible conductors that follow all movements of the leaf.

Insofar as FIGS. 7 to 9 represent states of the device which exactly correspond to those respectively illustrated in FIGS. 4 to 6, the explanations given with reference to FIGS. 4 to 6 are valid for FIGS. 7 to 9.

Moreover, insofar as the devices of FIGS. 4 to 6 and 7 to 9 partly use functionally similar components and identified by identical reference numerals, the description of these components with reference to FIGS. 7 to 9 will implicitly use the description. with reference to Figures 4 to 6.

Instead of being driven by a handle, the turntable 60 of the device of FIGS. 7 to 9 is driven by the electric motor 62, via the speed reducer 620. The rocking levers 51d and 51g, shaped as rockers, each comprise two branches whose common point is hinged at 500d and 500g on the support 510d and 510g corresponding, one of the branches being hinged at 50d and 50g on the corresponding link 71d and 71g, and the other branch being formed by axis carrying a roller 512d and 512g rotatably mounted and sliding on this axis.

The turntable 60 carries at least one radial relief 66 intended to cooperate with position detectors 93 and 94, detectors being mounted on the leaf 2 and constituting rotational end-of-travel detectors for the turntable 60.

When the leaf 2, in its position shown in Figure 7, is pushed in the closed position towards the frame 1, and reaches a position close to its closed position, the imminence of the closure is detected by the detector end of stroke 92 (FIG. 3), which changes state when approaching the guide carriage 82.

Provided that, simultaneously, the detector 93 detects the presence of the relief 66, the electric motor 62 is energized and rotates the plate 60 about the axis 600 via the reducer 620.

The rotation continues until the detector 94 detects in turn the presence of the relief 66, that is to say until the device reaches the position shown in Figure 9, the engine power 62 being cut off.

During any rotation of the turntable 60, the rollers 512d and 512g rest on the tabs 40d and 40g integral with the guide edges 12 and 14 of the frame, exerting forces Pz which gradually contribute to the compression of the seal J arranged between frame 1 and leaf 2.

In the position illustrated in FIG. 9, the device is blocked either by the knee-joint configuration adopted by the eccentrics 61d, 61g, the axis 600, and the supports of the rollers 512d, 512g, ie the irreversible nature of the movement as the Reducer 620 transmits its input to its output, either by the cumulative effect of these two phenomena.

The opening of the device from its configuration illustrated in Figure 9 is obtained by an electrical command, validated by the detectors 92 and 94, whose states confirm that the device is in the locked position.

The motor 62 is then controlled so as to rotate the plate 60, preferably in the opposite direction of the locking direction.

This rotation continues until the detector changes state and confirms that the tray has returned to its position shown in Figure 7, the power supply of the motor 62 is then cut.

FIGS. 10 to 12 show a device also according to the first embodiment of the invention, that is to say in which the locking means 6 are carried by the leaf 2, but realized according to the second variant, according to which the locking means 6 are provided on the free edges 02 and 204 of the leaf 2, respectively to move the corresponding fastening means, 51d and 51g, which are movably mounted the leaf.

This device uses two latching latches, 65d and 65g, of a type which will be described in detail with reference to FIGS. 13 to 16.

Each plate comprises a support 601 fixed to the corresponding free edge 202 and 204 of the leaf 2, motorized locking means 6 mounted on the support, and hooking means 5, movably mounted on the support 601, and therefore with respect to the leaf 2, and actuated by the locking means.

FIGS. 10 to 12 again represent states of the device which exactly correspond to those respectively illustrated in FIGS. 4 to 6 and FIGS. 7 to 9, and in part involve functionally similar components marked with identical reference numerals. so that the explanations given previously remain, mutatis mutandis, applicable to the device illustrated in these figures.

In this variant, it is therefore useful to provide that the electrical power and control conductors of the plates 65d and 65g are flexible and mobile to follow the movements of the leaf 2.

In fact, the specificity of the device of FIGS. 10 to 12 lies above all in the necessity that it engenders to ensure a synchronized operation of the plates 65d and 65g, this aspect being described with reference to FIGS. 13 to 16, which represent generically any of these plates.

As shown in these figures, such a plate always comprises a turntable selectively rotated about an axis 600 by a speed reducer 620 driven by an electric motor 62.

The plate 60 carries an eccentric 61, generically representing the eccentrics 61d and 61g, on which is coupled the end of a rod 71, generically representing the rods 71d and 71g.

The other end of the connecting rod 71 is connected to the rocking lever 51, which is shaped like a rocker, which generically represents the levers 51d and 51g, and which itself carries a roller 512 generically representing the rollers 512d and 512g.

The configuration illustrated in FIGS. 13 and 14 is that corresponding to the state of the device illustrated in FIG. 10, the eccentric 61 being in the minimum extension position, and the rocker arm 51 being correlatively in the retracted position to allow the free movement leaf 2 in relation to frame 1.

The configuration illustrated in FIGS. 15 and 16, on the other hand, is that corresponding to the state of the device illustrated in FIG. 12, the eccentric 61 being in the maximum extension position, and the rocker arm 51 being correlatively in the locked position to allow the locking the leaf 2 on the frame 1.

As best shown in Figures 13 and 15, a pivoting pawl 63 may be advantageously provided to engage, in the locking position, in a notch 60e arranged in the plate 60 and thus prevent any return back which would lead to unlocking .

To avoid play in the locking position, the notch 60e may be arranged to wedge the eccentric 61 in an angular position marked by an angle P of a few degrees, in advance of the dead point before this eccentric.

The synchronization of the plates and 65G of FIGS. 10 to 12 is obtained by providing each of these plates 65 with detectors 95 and 96, respectively playing the role of end-of-travel detector in minimum extension of the eccentric 61, and the detector role of end run in maximum extension of this eccentric 61.

When the leaf 2, in its position shown in Figure 10, is pushed in the closed position to the frame 1, and reaches a position close to its closed position, the imminence of the closure is detected by the detector end of stroke 92 (FIG. 3), which changes state when approaching the guide carriage 82.

Provided that, simultaneously, the detector 95 of each plate 65 detects the presence of the eccentric 61 of this plate, the corresponding electric motor 62 is energized and rotates the corresponding plate 60 about the axis 600 via the reducer 620.

The rotation continues until the detector 96 of each plate 65 detects in turn the presence of the eccentric 61 of this plate, that is to say until the device reaches the position illustrated in FIG. Figure 12, the motor 62 of the same platinum then being cut.

During the entire rotation of the turntables 60 of the plates 65d and 65g, the rollers 512d and 512g are based on the tabs 40d and 40g integral with the guide edges 12 and 14 of the frame, exerting forces which progressively contribute to the compression of the joint sealing ring J arranged between the frame 1 and the leaf 2.

The opening of the device from its configuration illustrated in Figure 12 is obtained by an electrical command, validated by the detector 92 and the detector 96 of each plate 65, the states of these detectors confirming that the device is in the locked position.

The motor 62 of each plate 65 is then controlled so as to ensure the rotation of the plate 60 of this plate, in the opposite direction of the locking direction.

This rotation continues until the detector 95 of each plate 65 changes state and confirms that the plate 60 of this plate has returned to its position shown in Figure 13, the supply of the corresponding motor 62 is then cut.

FIGS. 17 to 19 show a device according to a second embodiment of the invention, in which locking means 6 are provided on each guide edge 12 and 14 of the frame 1, in order respectively to move the corresponding fastening means 41d and 41g mounted mobile on the frame.

The device according to this second embodiment can thus use plates 64d and 64g, identical to the plates 65d and 65g, but respectively fixed on the guide edges 12 and 14 of the frame 1, the distinction between the references "65" and " 64 "being justified only by the fact that the attachment means carried by the plates 64d and 64g are finally carried the frame 1 and not by the leaf 2. The attachment means carried by the leaf 2 take as to they, for example, the shape of legs with "S" profile, marked by the references 55d and 55g.

synchronization of the plates 64d and 64g in this second embodiment is obtained in the same way as for the device of Figures 10 to 12, the main difference being that all electrical power and control wiring of the device of Figures 17 to 19 are fixed instead of having to move with leaf 2.

For the rest, those skilled in the art will understand, from reading the foregoing description, that FIGS. 17 to 19 represent states of the device respectively corresponding to the states illustrated in FIGS. 10 to 12.

FIGS. 20 and 21 schematically represent a device also according to the second embodiment of the invention, that is to say in which locking means 6 are provided on each guide edge 12 and 14 of the frame, but realized according to a second variant of execution.

In this version of the device the invention, the attachment means 5 provided on the leaf 2 take the form of two hooks such as 56, each of which constitutes an open strike fixed on a corresponding free edge, 202 or 204, of this leaf 2, and the attachment means 4 provided on the frame 1 take the form of two bolts, such as 46, each of which consists of a finger mounted eccentrically on a turntable 60 and engageable by rotation of this plate, in the corresponding hook 56.

In addition to the turntable 60, the locking means 6 comprise an electric motor 62 and a reducer 620 connecting this motor to the plate 60.

As in the preceding examples, and in particular that illustrated in FIGS. 17 to 19, the device comprises limit detectors capable of detecting and controlling the states taken by the device.

FIG. 20 illustrates a crossed crossing configuration of the attachment means 46 and 56, which as soon as it is detected, triggers the electric motor supply 62 and the corresponding rotation of the plate 620, to the position illustrated in FIG. which hooks 56 have been driven respective penes 46 over a sufficient travel so that leaf 2 is firmly applied to frame In all embodiments using an electric motor 62 - reducer 620, the engine power and the ratio of The reduction will be chosen so as to develop a sufficient closing assistance force P2 to ensure good compression of the seal J.

All the electromechanical components as well as various connections to the leaf and the frame will be amply dimensioned to ensure the safety of closing, as well vis-à-vis the efforts generated the use and the displacements of the vehicle as to oppose to possible intrusion attempts.

hooking plate - locking will be arranged in such a way that, in the closed position, the movement is irreversible, either by the relative arrangement of the components in the bridging position possibly assisted by a pawl, or the inherent irreversibility of the motor reducer assembly.

The device which is the subject of the invention may also comprise a complementary locking device capable of reinforcing the holding of the guided edge 203 leaf 2 with respect to the releasable edge 13 of the frame 1, in particular in the case where the inherent rigidity of the leaf 2 is insufficient. possibly as a result of the use of a single lateral guide rail 81. As shown in FIGS. 27, this complementary locking device comprises, for example, a locking pin 83 disposed on a guided edge 203 of the leaf 2 and a support of guide 84 secured to the releasable edge 13 of the frame 1, the locking finger 83 and the guiding support 84 cooperating, in the closing position of the leaf, to urge the leaf 2 against the frame 1.

The guiding support 84 is in the form of a roller rotatably mounted on an axis integral with the frame 1 and on which the locking finger 83 is rolled which projects beyond the guided edge 203 of the leaf 2.

The inclination of the finger movement 83 is such that this finger is subjected to a lateral force P3 which contributes to the compression of the seal provided between the leaf 2 and the frame 1.

In order for this force to be able to function correctly, however, the oblique movement of the finger must not be thwarted by the guidance provided by the mobile carriage 82 and the rail 81.

To this end, a first solution, illustrated in Figures 22 to 24 is to provide wheels of the guide carriage 82 elastic bandages allowing the leaf 2, thanks to the crash E that can undergo these elastic bandages, to follow the path imposed by the engagement of the locking finger 83 and the guiding support 84.

A second solution, illustrated in Figures 25 to 27 is to grant some flexibility to the lower part of the guide rail 81 allowing the leaf 2, thanks to the elastic deflection of amplitude E that can undergo this rail, to follow the imposed path by the cooperation of the locking finger 83 and the guide support 84.
