Description

Shutter device for a bay formed in a motor vehicle equipped with anti-tilt means, and corresponding vehicle. FIELD OF THE INVENTION The field of the invention is that of motor vehicle bays. More specifically, the invention relates to shutter devices for a bay formed in the bodywork of a vehicle, and comprising a fixed portion attached flushly to the body, by gluing, and a movable sliding part, essentially glazed , likely to release or close an opening in the fixed part. 2. Prior art techniques Conventionally, to seal the bay of a vehicle, be it an automobile, a commercial vehicle, a truck, a bus or a vehicle. railway wagon, an ice cream is reported, maintained by a connecting frame. The latter has an inner part and an outer part, which simultaneously pinch the edges of the ice and the opening in the body, with a seal. Another technique is described in particular in patent documents EP 0 778 168 and EP 0 857 844, in the name of the owner of the present patent application. The shutter device presented in these documents (hereinafter called flush bay) comprises a fixed part comprising a glazed portion, and a substantially glazed part movable relative to the fixed part. The movable part 25 is connected to the fixed part by functional elements, or rails, which allow the required mobility and which are reported on the face of the fixed part turned towards the inside of the vehicle. These rails are secured to the fixed part (or formed directly therein for example by molding or overmolding), on the face thereof facing the vehicle interior. Thus, aesthetically, the flush bay presents, from the outside, a smooth appearance, flush with the body, because no frame is needed between the body and the fixed part. A flush appearance is also obtained between the fixed part and the moving part, when it is closed, by the presence of means bringing it back into the plane of the fixed part.

The rails make it possible to control, on the one hand, the sliding displacement of the movable panel, and, on the other hand, the passage of this movable panel from the plane of the fixed part, in the closed position, to a neighboring plane, allowing sliding displacement. Depending on the configuration of the vehicle, and thus the shape of the bay to be closed, the rails can be adapted, by their dimensions and / or their location. Thus, when the bay is essentially rectangular, the rails can be parallel, and of similar lengths. For bays of substantially trapezoidal shape, non-parallel rails have been proposed. In certain situations, the shape of the bay is more particular, and has for example, in the case of a bay intended to equip a lateral element of the bodywork, with a movable panel substantially horizontally, a lower side of shorter length than on the upper side (or vice versa). This may be the case in particular when the edges extending substantially vertically are not parallel, or at least one of them is not rectilinear, the bay having for example a truncated corner. In this case, one of the rails is shorter than the other, and the movable panel may be subject to inadvertent tilting, also called swaying or dislocation, that is to say, it can pour, instead to remain perfectly in its normal sliding position, at least in an end position, in which it is guided by only one rail. This can occur especially when the user does not print on the moving panel a force remaining parallel to the sliding axis, to move it. This situation can also be encountered in the case where a single rail is provided for guiding the movable panel.

This tilting phenomenon can lead to a blocking of the movable panel (in an unclosed position), to a deterioration of the rail, and even in certain extreme situations to the separation of the movable panel and the rest of the closure device. Clearly, this situation is not acceptable, in terms of perceived quality and user satisfaction, but also, and mainly, that of safety (of people and goods in the vehicle). 3. OBJECTIVES OF THE INVENTION The invention particularly aims to overcome these disadvantages of the state of the art.

More specifically, an object of the invention is to provide a closing technique of a motor vehicle bay implementing a movable sliding glass panel guided in rails along a fixed glazed portion, which make it possible to fight against the phenomena of untimely swaying. More specifically, a particular object of the invention is to provide such a technique which allows, according to at least one particular embodiment of the invention, to efficiently and reliably guide a movable panel, when the rails do not exhibit the same length, or only one rail is used. Another object of the invention is to propose, according to at least one particular embodiment of the invention, such a shutter technique which is well adapted to complex shapes of bay, and for example to non-rectangular bays, and having a truncated corner. Another objective of the invention is to provide, according to at least one particular embodiment of the invention, such a closure technique of a bay, which retains various advantages of flush bays already developed by the holder of this request, and in particular: - exterior aesthetic appearance flush; - aerodynamic appearance; - security in case of breakage of the fixed part; - ease of assembly on the vehicle 4. Description of the invention These and other objects which will appear later are achieved by means of a closure device of a bay formed in the bodywork of a motor vehicle, comprising a fixed part in which is defined an opening, and a movable glass panel capable of closing or releasing said opening, said movable glass panel carrying at least a first guide and / or holding element extending in a first plane substantially parallel to the plane defined by said movable glass panel and cooperating with a corresponding groove formed in a first guide rail mounted on said fixed part, along a substantially horizontal axis. According to the invention, said movable glazing panel comprises at least a second guide and / or holding element extending in a second plane substantially perpendicular to said first plane, and cooperating with said rail so as to avoid tilting of said movable glass panel .

Thus, the invention proposes the implementation of one (or more) element mounted on the movable panel, able to suppress a degree of freedom in the movement of the movable panel, to prevent it from pouring, or to be swung, in particular in a position where two rails are not present to hold it sufficiently.

In other words, the second guide member provides plugging, preventing this unwanted movement. According to a particular embodiment of the invention, the first rail is an upper rail, mounted above said opening, and the said second or second guide and / or holding members come to bear on and / or in said first rail, so as to maintain said mobile glass panel suspended relative to said first rail. According to a variant of the invention, it is also possible to provide such second guiding and / or holding members on a lower rail. In some cases, such a first upper rail may be sufficient to control the movement of the movable panel. In other cases, a second rail mounted below said opening is provided. It can then, depending on the shape of the particular bay, extend a shorter distance than said first rail. The at least one second guiding and / or holding member is preferably defined, in the latter case, so as to act at least in an area of said first rail opposite which said second rail is not present. According to a first embodiment of the invention, at least one of said second guiding and / or holding elements has a bearing surface coming to rest on an upper surface of said first rail.

This support surface keeps the panel suspended, and prevents it effectively and simply to tip. According to a second embodiment of the invention, at least one of said second guiding and / or holding elements has a guiding portion which is housed in a housing provided for this purpose in said first rail, and extending according to said foreground. This housing can be likened to a second slide, the rail then carrying two slides, extending substantially perpendicular to one another. Advantageously, said movable glass panel carries a frame, from which extend said second or second guiding and / or holding members. Thus, these second elements are simple to implement and implement without a complex step. They can in particular be formed, for example simultaneously with the frame, by molding, or reported on it, by overmolding, clipping, gluing, ...

In particular, said frame may comprise a flank substantially parallel to said first plane and covering at least a portion of said first rail, from which extends said second or second guiding and / or holding members. According to yet another approach of the invention, at least one of said first guiding and / or holding elements and at least one of said second guiding and / or holding elements are formed in the extension of one another. Thus, in a third embodiment of the invention, there is provided a guide piece having a T-shaped section, a first bar of said T corresponding to said first guide element and / or of maintaining the second bar of said T corresponding to said second element guiding and / or holding. This gives a simple and discrete implementation. According to a fourth embodiment, the movable panel carries a guide piece having an L-shaped section, a first bar of said L corresponding to said first guide member and / or holding the second bar of said L corresponding to said second guide member and / or keeping. In particular, in this case, said groove may be open on the side of said first rail opposite to the near side of said opening. This gives a hooking from above the rail. According to one embodiment of the invention, at least one of said first elements is a guiding and / or locking pin. Thus, the first element or elements are of reduced size, to allow a sway, for example. The second elements may be of larger size, and if necessary extend over the entire width of the movable panel. According to another aspect of the invention, said movable glazing panel may carry at least one positioner element capable of cooperating with a support surface provided for this purpose on the fixed part, when said mobile glass panel is in the closed position, of in order to improve the tightness, the inviolability and / or the closure of said mobile glass panel. The invention also relates to a motor vehicle comprising at least one closure device as described above. 5.

DETAILED DESCRIPTION OF AN EMBODIMENT OF THE INVENTION 6.1 Reminders on the flush bay The invention therefore applies to flush berries, of the type already described briefly in the preamble, and an example of which is illustrated in FIG. 1. An example of a flush bay is illustrated schematically in FIG. 1. Such a flush bay firstly comprises a fixed part 11, totally or essentially glazed. As shown in Figure 1, which has the side intended to be oriented towards the inside of the vehicle, the periphery of the fixed panel 11 is free (with the exception of the elements 121 122 131 132 whose functions are recalled below) ).

Thus, the closure device of Figure 1 can be attached directly to the edges of a bay defined in the body of a vehicle from outside the latter. These edges of the bay are made with a slight withdrawal, corresponding substantially to the thickness of the fixed panel 11, so that it is flush with the rest of the body, when mounted.

In particular, the bay may be formed in a side wall of the vehicle (for example for commercial vehicles, minivans, station wagons, ...), in a wall facing the rear of the vehicle (for example for pick-ups ), in a roof (the shutter device can then form a roof or a portion of glazed roof), or in a door (in this case, the edges of the bay may be partly formed by receiving elements s extending from the box of the door, the device then being attached to the upper edge of the box and the receiving elements which extend therefrom). A seal, or bead, of glue (not shown) is placed around the perimeter of the fixed panel, or on the edges of the bodyshell, and the periphery of the fixed panel 11 is thus directly secured by gluing, to the edges of the bay, without the need for a frame or any other intermediate link. The bead of glue also advantageously provides a sealing function. An opening 14 is made in the fixed panel 11. As seen in Figure 1, the edges of this opening 14 are spaced from the periphery of the fixed panel 1l, to allow the attachment thereof to the edges of the bay, as explained above. The fixed panel 11 can be made in the form of a single glazed element, made of glass or plastic adapted to the application to the automobile, in which the opening 14 is formed. By glazing, any suitable material is understood here. to let at least partially the light (transparent material, translucent, tinted, ...). The fixed panel 11 can also be made of several constituent elements, these elements can then each define one or more sides of the opening 14. Such an approach allows in particular to simplify the production of the opening 14 in a glass panel. Of course, in this case, the various elements constituting the fixed panel are in the same plane (which can, in some cases, be curved or curved in at least one dimension, for example to follow a curve of the body) . Indeed, seen from the outside, the fixed part must have a smooth appearance, or flush.

The joining of these different constituent elements can be done by any suitable means, for example by gluing. The rails 151 and 152 can participate in this connection. It is possible, without departing from the scope of the invention, that one of the elements of the fixed part is not glazed. According to one variant, the fixed part 11 may comprise a support element, for example made of plastic, defining in particular the periphery of the fixed part, and pierced with two openings, one being definitively closed by a fixed mounted glazed element. , and the second corresponding to the opening 14. The support member and the fixed glazing element are in the same plane, so as to define a smooth surface, seen from the outside.

Such a closure device according to the invention further comprises a movable panel 16, which can close or clear the opening 14. This movable panel 16 is also glazed. It is held and guided by two rails 151, 152, which are mounted on the face of the fixed panel facing the vehicle interior and away from the periphery of this fixed panel, for the reasons already explained above. The movable panel 16 can be moved (or move, if motorization means are provided) along the rails 151, 152, in a plane of sliding substantially parallel to the plane defined by the fixed part 11. Thus, the movable panel 16 can take one or more opening positions, according to its position relative to the rails 151, 152. Furthermore, the movable panel 16 can move perpendicularly to the plane defined by the fixed panel 11, so as to close the opening 14, in a closed position, in which it is flush with the fixed panel 1l, so as to provide a flush assembly (body, fixed panel and movable panel).

The movement of the movable panel 16 with respect to the fixed part 11 may, according to a first approach, be broken down into two independent displacements: a displacement perpendicular to the plane formed by the fixed part, allowing the passage of a closed position, and locked, in which the movable panel is in the same plane as the fixed part, that the opening to a release position, in which the movable panel is offset from the fixed part in a sliding plane, of to allow this sliding; a displacement in the plane of sliding, parallel to the plane formed by the fixed part. Other movements are of course possible. Thus, according to a second approach, the movable panel can skew, that is to say follow a curve according to which the two movements (locking / unlocking and sliding) are related to the moment of opening and closing.

The rails 151 and 152 may be secured to the fixed part 11 by gluing or by any other suitable means. They can also be directly formed, for example by molding or overmoulding, on the fixed part 11. They are generally concealed, as are the other functional elements, by screen printing, preventing them from being seen from outside the vehicle. .

In some cases, the rails may be non-parallel. Furthermore, it is important, for reasons of safety (and consequently of approval with regard to regulatory and / or legislative aspects relating to the safety of the vehicles) that the rails 151, 152 are attached to the bodywork, and more precisely at the edges of the bay. In fact, according to the European regulation EC43 for example, it is imposed that, in the event of breakage of glass (in this case of the fixed part 11), the elements likely to be projected have a smaller size and / or a lower weight. at a predetermined limit, greatly exceeded by the rails or the movable panel. However, it is understood that if nothing is provided, in case of breakage of the fixed part 11, neither the rails 151, 152 nor the movable panel 16 will be maintained.

They will be projected, and may therefore injure a passenger of the vehicle or a passerby. As has been proposed in patent document EP-0 778 168, the holder of the present application has therefore proposed to equip the extension rails 121, 122, 131, 132, which extend on the face facing the the interior of the vehicle of the fixed part 11, so as to be sandwiched between the edge of the fixed part 11 and the corresponding edge of the body of the body. Thus, the bead of glue solidarisant the fixed part 11 to the body also secures these extensions 121, 122, 131, 132 at the edge of the vehicle body. Consequently, even when the fixed part 11 is broken, and therefore absent, the rails are held in place relative to the bodywork using these extensions. These rails 151 and 152 maintain the movable panel 16. These extensions can be formed by molding directly in the rail, or be reported thereon by any suitable means, for example by gluing or clipping.

The lower rail 152 carries extensions 131, 132 also having an opening sufficient to allow the evacuation of water collected in the rail 152, corresponding for example to the condensation in the vehicle. This water is thus simply and efficiently evacuated outside the vehicle without affecting the watertightness. The functions of maintenance in case of breakage and evacuation of water, can of course be provided by separate elements. The movable panel 16 carries in the illustrated embodiment, a frame 17 on its side facing towards the inside of the vehicle. This frame 17 does not extend on the other side, so as to preserve the flush appearance. It carries at least one upper guide pin 181 and a lower guide pin 182 provided for being guided in a corresponding slide formed respectively in the rails 151 and 152. Other pins may also be provided for the desired guidance. In the illustrated embodiment the guide is completed by complementary elements 191, 192 which simultaneously provide a bolt function cooperating with strikes provided for this purpose in the rails 151 152 so as to lock the movable panel in its closed position ( where appropriate in one or more predetermined opening positions). A handle 110 is mounted on the frame 17, to actuate the unlocking of the bolts and slide the movable panel. According to the illustrated embodiment, the two rails 151 152 are formed in one and the same part comprising a connecting element 111, extending between the two rails, along an edge of the movable panel 16, this part is glued to the fixed part 11. 6.2 Particularities of the bay of FIG. 1 As seen in FIG. 1, the fixed part 11 has a truncated corner 112, necessitated by a particular shape of the body and or aesthetic or safety requirements. As a result, the upper edge of the fixed portion is substantially longer than the lower edge. As a result, the upper rail 151 has a length also greater than that of the lower rail 152 (left part of Figure 1).

Moreover, the shape of the movable panel 16 also has a truncated corner imposed by the corresponding shape of the fixed part. Therefore, when the movable panel 16 is in the position shown in Figure 1, it has a tendency to sway, or spill, especially if the force applied to the movable panel 16 is not perfectly parallel to the sliding axis. Indeed, the reduced length of the rail 152 does not ensure sufficient maintenance of the movable panel 16, which could move unintentionally, for example according to the arrow 113. To avoid this problem, the invention proposes to equip the panel movable 16 second guide and or holding means for preventing such movement along the arrow 113 in particular. Thus, according to the invention, the movable panel 16 carries on the one hand first guide means 181, 182, 191, 192 providing a guide along the sliding axis, and secondly second guide means and / or maintaining 114, removing a degree of freedom that may appear, especially in the area where the rail 152 does not extend. 6.3 First embodiment. This first embodiment is illustrated in Figure 1, and shown in section in Figure 2. More specifically, this Figure 2 shows a sectional view AA of the upper part of the flush bay of Figure 1. As seen in this FIG. 2, the rail 151, secured to the fixed part 11, has a slideway (sliding guide zone) 21, in which the pin 181 circulates. This slideway 21 is not entirely parallel to the rail axis. 151 but has a suitable profile (ending for example in an arc) to allow the sliding of the movable panel 11. The frame 17 of the movable panel 11 also advantageously carries a seal 22, the end of the lip comes to bear on the fixed part 11, when the movable panel 16 is in the closed position. The frame 17 also carries, in accordance with its embodiment, an element 23, forming an angle, and coming to cover the rail 151. Thus this bracket 23 has a flank 231 extending vertically, and a bearing portion 232 perpendicular to the flank 231 and coming to rest on the upper surface 151 on rail 151. Thus, the movable panel 16 is held suspended from the rail 151 by means of this support element 232, and can not be swung according to the movement of the arrow 113 The angle 23 thus ensures that movement of the movable panel 16 will remain along the axis of sliding. For aesthetic reasons in particular, the angle 23 extends substantially over the entire width of the movable panel 16. However, it is understood that, according to other embodiments, it could extend only over a portion of this width, or have two (or more) support legs. 6.4 Second embodiment. According to a second embodiment, illustrated in FIG. 3, the support element of FIG. 2 is replaced by a guide element 31, formed in the extension of the sidewall 32, itself connected to the frame 17 (of FIG. similar to the embodiment of Figure 2). This guiding element 31 penetrates and circulates in a groove 33 formed in the rail 151. This groove extends horizontally or substantially horizontally, the rail 151 therefore has, in this embodiment, two guiding zones 21 and 31. extending substantially perpendicularly with respect to each other. Similarly, for the first embodiment, the guide member 31 and the flank 32 may extend over the entire movable width 16, a portion thereof, or be made of a plurality of elements, e.g. pions. 6.5 Third embodiment. According to this third embodiment, illustrated in FIG. 4, the guiding pin 181 is eliminated at least in the form shown in FIG. 1. The rail 151 carries a groove 41 formed on its upper surface, that is to say on the surface opposite to the movable panel 16. In a manner similar to the technique described in the first embodiment, the frame has an angle bracket 42, comprising a vertical side 421 and a support element 422, bearing on the upper surface of the rail 151. The pin 44 extends from this support element 432 to penetrate the groove 41. The pin 44 and the support element 422 thus define an L-section. Again, according to this approach, there is a simple and effective way of guiding by the pin 44 and support by the element 432. 6.6 Fourth embodiment FIG. 5 presents a fourth embodiment, in which the second holding member and / or guidance is formed on 181. In this embodiment, as illustrated in FIG. 5, the groove 51 for guiding the pin 181 firstly comprises a conventional vertical portion 511, which terminates on a horizontal portion 512. Similarly, the pin 181 comprises a first vertical conventional portion 181, and ends with a complementary element 182, extending horizontally so as to cooperate with the horizontal portion 512 of the groove. It is understood that, thus, by this dovetail mechanism, the movable panel 16 is kept suspended, and can not be swung. According to this embodiment, the portion 182 must be dimensioned so as not to interfere with swaying and guiding. It will therefore be a reduced-size element, for example of circular shape, and mounted if necessary in the form of a wheel. It is also possible to separate the pin, which then retains its usual shape, an element whose section has a T-shape, flowing in the groove, in an area where it is rectilinear.

Furthermore, the T-section can be replaced by a separate section, for example in cross when the suspension is ensured. 6.7 Details and variants. In the various embodiments illustrated above, the second guiding and / or holding means may be made in the same room as the frame 17, for example by molding or overmolding. It can also be patches. In some different embodiments, depending on the manufacturing constraints and / or the shape of the bay, the lower rail may be completely absent. In this case, however, the movable panel remains properly maintained and suspended. In addition, always according to the needs, the role of the upper and lower rails can be reversed. 6.8 Positioning Means Since the bottom track 152 of the flush bay of Fig. 1 does not extend as far as the top rail 151, the lower portion of the movable panel, on the opposite side of the locking means (ie say in the area with a truncated corner) may be insufficiently guided, especially during the sway for closing, that is to say the passage of the movable panel in the plane of the fixed part. Moreover, when this panel 16 is closed, the seal may be insufficient in this area. Indeed, a jet of water under pressure could cause a slight deformation, since this area is not maintained by the lower rail 152, which would leave the water inside the vehicle.

Finally, for the same reason, a careless person might succeed in shifting slightly this area, for example to introduce a tool to try to enter the vehicle. In order to meet these various problems, it is provided, as illustrated in FIG. 6, which has an enlarged area 115 of FIG. 1, a positioner element 61, configured to cooperate with a corresponding bearing surface 62, secured to the fixed part 11, and in this case formed in the connecting element 111 between the two rails 151 and 152. As seen in this figure 6, the positioner element 61 is formed slightly behind the thickness of the frame 17, and engages with the bearing surface 62, so that, during the swaying, these two elements hold the movable panel 11 and help its swaying. Furthermore, when the movable panel is in the closed position, the positioner 61 is in abutment against the bearing surface 62, preventing any displacement of this zone of the movable panel 16, in particular when a jet of water under pressure is applied. or that a careless person tries to move the movable panel 16, in a direction perpendicular to the plane of the fixed part.
