Description

INTERFACE DEVICE BETWEEN A LATCH AND A LOCK OF A VEHICLE DOOR, WITH WHEELS, CABLE (S) AND BYPASS The invention relates to the locking / unlocking of sliding window doors which are fitted to certain vehicles, possibly of the automotive type. . Certain vehicles, possibly of automobile type, comprise 1 o at least one door comprising a box, in which can slide a window, a lock, operable by means of a key, and a lock, offset relative to the lock. This offset may consist of a shift in a transverse direction and / or in a longitudinal direction and / or in a vertical direction relative to the lock. Here "longitudinal direction" is understood to mean a direction which is substantially parallel to the lateral sides of the vehicle which comprise the side doors, by "transverse direction" a direction which is substantially perpendicular to the lateral sides of the vehicle and therefore to the longitudinal direction, and by "vertical direction" a direction which is substantially perpendicular to the floor of the vehicle and thus to the longitudinal and transverse directions. As known to those skilled in the art, the offset of the lock can have several origins. Indeed, it may result from a style effect, or a constraint related to the shape of the door or to the arrangement of the door box, or a desire to improve the ergonomics, or compliance with regulations (eg on shocks). In order to mechanically couple the lock and the remote lock, several solutions have been proposed. A first solution is to use a rigid rod (or rod) 30 which is secured to two rotary lugs (or levers) which are respectively part of the lock and the lock, and which may optionally comprise two or three subparts with orientations different spatial two by two. Alas, this first solution imposes large deflections of the levers and the connecting rod, and therefore requires a large volume between the rear edge of the sliding window and the rear wall of the door box, especially when using an anti crankcase. -breaking in. Therefore, this first solution can not be used when the rear edge of the sliding window is located very close to the rear wall of the door box. In addition, the rod may, by deforming, increase the length of the locking / unlocking races, which can cause a failure. In addition, the vibrations and door closures cause small movements of the rod and levers that can generate unpleasant noises. A second solution is to use a cardan, possibly slightly offset from the transverse direction. This second solution does not allow picking, by means of a hook introduced between the window and the seal, it is therefore safer than the previous vis-à-vis burglaries. However, the gimbal is installed substantially transversely, it is on the path of the sliding window when the rear edge of the latter is located very close to the rear wall of the door box, including when it is off-axis. A third solution consists in using a gear comprising at least three gears which are placed substantially in a plane defined by the longitudinal and vertical directions, and the last of which is coupled to the lock via an axis or a gimbal, possibly slightly off-axis with respect to the transverse direction. This third solution has the same disadvantage as the second solution because of the use of an axis or a gimbal, even off-axis. To deviate more from the window can be used a larger number of gears, but this can affect performance, and it can not be implemented when the vertical offset between the lock and the lock is not important. A fourth solution consists in using a belt mounted on two wheels placed substantially in a plane defined by the longitudinal and vertical directions. The upper wheel is coupled to the lock via an axis or a universal joint, possibly slightly offset from the transverse direction, and the lower wheel is coupled to the lock via another axis or another cardan, possibly slightly off-axis with respect to the direction. cross. This fourth solution makes it possible to obtain a significant vertical and / or longitudinal offset without loss of efficiency, but it does not make it possible to obtain a large transverse offset due to the space occupied by the lower wheel. Therefore, this fourth solution is also not suitable for the case where the rear edge of the sliding window is located very close to the rear wall of the door box due to the use of an axis or a gimbal even misaligned. The object of the invention is therefore to propose an alternative solution which is particularly suitable for situations in which, on the one hand, the lock is deported at least transversely with respect to the lock, and, on the other hand, the rear edge of the Sliding pane is located very close to the back wall of the door box. It proposes for this purpose a device, intended to serve as an interface between a lock and a remote lock at least transversely in a vehicle door having a box in which can slide a window, and comprising: - a first wheel, suitable for being coupled in rotation to the latch and to which at least one cable is coupled, - a second wheel to which each cable is coupled, - a first transfer pinion coupled in rotation to the second wheel, and - a shaft intended to bypass the window regardless of its position in the box, and having a first end provided with a second transfer pinion meshing with the first transfer pinion and a second end adapted to be coupled to the lock to cause its actuation when driven in. rotation. This interface device advantageously allows to bypass the sliding window, including when its rear edge is located very close to the rear wall of the door box, possibly substantially at the height of the door handle. In addition, it induces almost no parasitic noise and can deform only very slightly, which guarantees its reliability. The interface device according to the invention may comprise other characteristics that can be taken separately or in combination, and in particular: the second end of the shaft may be provided with a third transfer pinion. In this case, it may comprise an output gear meshing the third transfer gear and adapted to be coupled to the lock to actuate the latter when it is rotated; the third transfer pinion can be coupled to the lock via an axis; the shaft, the second transfer pinion and the possible third transfer pinion can be part of the same one-piece part; its shaft may be intended to extend substantially transversely in the box; it may comprise two cables each having first and second ends secured respectively to the first and second wheels at different locations so that when one of the cables is driven in a first direction because of the rotational drive of the first wheel by another axis coupled in rotation to the latch, the other cable is driven in a second direction opposite the first direction; its first transfer pinion and its second wheel can be part of the same one-piece part; - Its first and second wheels can be shifted relative to each other in a longitudinal direction to participate in bypassing the glass; it may comprise a housing in which are installed the first and second wheels, the shaft, the first, second and possible third transfer gears, each cable, and the possible output gear.

The invention also proposes a locking system, intended to equip a vehicle door comprising a box in which a window can slide, and comprising a lock, a lock offset at least transversely in the box, and an interface device of the type of the one presented above and ensuring the interface between the lock and the lock.

The invention also provides a vehicle door, comprising a box in which can slide a window, and a locking system of the type shown above.

Other features and advantages of the invention will become apparent upon examination of the detailed description below, and the accompanying drawings, in which: FIG. 1 schematically illustrates, in a side view, a portion of a door of vehicle comprising a sliding window and a locking system comprising an exemplary embodiment of an interface device according to the invention, without a protective casing to facilitate understanding, FIG. 2 schematically illustrates, in a view from above in an XY plane, the door part of FIG. 1 with its locking system, FIG. 3 schematically illustrates, in a sectional view along line III-III of FIG. 1, the door part of FIG. 1 with its locking system, FIG. 4 schematically illustrates, in a perspective view, the interface device of FIGS. 1 to 3 without a protective case, and FIG. 5 schematically illustrates, in a perspective view, the interface device of Figure 4 with its protective housing. The attached drawings may not only serve to complete the invention, but also contribute to its definition, if any. The invention aims to provide an interface device D for providing the interface between a lock VR and a remote lock SR of a locking system of a PV door of a vehicle with sliding window VT. Here, the term "locking system" means an assembly consisting of at least one lock VR, a remote lock SR and an interface device D according to the invention.

In what follows, it is considered, by way of non-limiting example, that the vehicle is automotive type. This is for example a car. But the invention is not limited to this type of vehicle. It concerns indeed any type of vehicle comprising at least one sliding glass door and a locking system. Thus, it also concerns trucks, commercial vehicles, coaches or buses, construction machines and aircraft, for example. In FIGS. 1 to 5, the direction X is the longitudinal direction of the vehicle, which is substantially parallel to the lateral sides including the side doors PV, the direction Y is the transverse direction of the vehicle, which is substantially perpendicular to the lateral sides and therefore to the longitudinal direction X, and the direction Z is the vertical direction of the vehicle, which is substantially perpendicular to the floor on which the vehicle rests and thus to the longitudinal directions X and transverse Y. is schematically shown in Figures 1 to 3 a portion of a vehicle PV gate comprising a sliding window VT and a locking system comprising an exemplary embodiment of the interface device 10 according to the invention. Note that in the non-limiting examples illustrated in Figures 1 to 3, the lock VR is part of the PP handle for opening the PV door. But this is not obligatory. It could indeed be independent of it, especially when it is offset vertically and / or longitudinally of the handle. It will also be noted that the lock VR can be actuated by means of a key. As illustrated in FIGS. 1 to 3, an interface device D according to the invention comprises at least a first wheel R1, a second wheel R2, at least one cable CBi, a first transfer gear PT1 and a shaft AR. The first wheel R1 is adapted to be coupled in rotation to the lock VR. As illustrated without limitation in FIGS. 1 to 5, this coupling can be done by means of a first axis A1, sometimes called a "bolt return". Note that in the illustrated example, the first axis A1 is substantially parallel to the transverse direction Y, but this is not mandatory. The first axis Al has a first end which is intended to be introduced into an element of the mechanism of the lock VR. For example, this first end may have a cylindrical shape having a polygon-shaped section (for example a hexagon) and the element of the lock VR may comprise a housing of a shape homologous to this section. Furthermore, the first axis A1 has a second end which is intended to be introduced into the first wheel R1. For example, this second end may have a cylindrical shape having a polygon-shaped section (for example a hexagon) and the first wheel R1 may comprise a housing of shape homologous to this section. Note that the first axis Al may be part of the interface device D. But this is not mandatory. It can indeed be part of the mechanism of the lock VR. The second wheel R2 is adapted to be coupled indirectly to the lock SR, via at least the AR shaft, as will be seen later. Each cable CBi comprises first and second opposite ends which are respectively coupled to the first R1 and second R2 1 o wheels. Note that in the embodiment shown in non-limiting manner in FIGS. 1 to 5, the interface device D comprises two cables CB1 and CB2 (j = 1 or 2), the first and second ends of which are firmly fixed respectively to the first and second ends. R1 and second R2 wheels in different places. Thus, when one of the cables (for example CB1) is driven in a first direction because of the rotational drive of the first wheel R1 by the first axis A1, the other cable (for example CB2) is driven according to a second meaning that is opposed to the first meaning. But in an alternative embodiment the interface device D may comprise only one cable secured to the first R1 and second R2 wheels, and possibly in the form of a closed loop. It will also be noted that in the exemplary embodiment illustrated in non-limiting manner in FIGS. 1 to 5, the first R1 and second R2 wheels each comprise a peripheral groove RP defining a guiding groove for each cable CBi. This facilitates the rotational drive of the second wheel R2 by the first wheel R1 and thus the placement in locking and unlocking positions. But this is not obligatory. The first transfer pinion PT1 is rotatably coupled to the second wheel R2. It should be noted that the first transfer pinion PT1 and the second wheel R2 may possibly be part of the same one-piece part. For example, the teeth of the first transfer gear PT1 may be defined in a front or rear face of the first wheel R1. But this is not obligatory. They could indeed be secured to one another, for example by screwing, gluing, welding or clipping. It will also be noted that in the exemplary embodiment illustrated in non-limiting manner in FIGS. 1 to 5, the first R1 and second R2 wheels are offset relative to each other in the longitudinal direction X and in the vertical direction Z. In FIG. in other words, the first R1 and second R2 wheels are not aligned in the vertical direction Z. Thus, they participate in bypassing the glass VT, and more precisely to the longitudinal bypass. But this is not obligatory. The AR shaft is designed to bypass the VT pane irrespective of its position in the CP box. Note that in the embodiment shown in non-limiting manner in Figures 1 to 5 the AR shaft extends substantially transversely (along Y) in the box CP. It is therefore substantially parallel to the first axis A1. But this is not obligatory. It could indeed make an angle different from 0 ° with respect to the transverse direction Y and / or make an angle different from 90 ° with respect to the vertical direction Z. In a general manner, the interface device D can allow an offset of the transverse VR lock and optionally longitudinal and / or vertical. The distance between the rear edge of the glass VT and the rear wall PR of the box CP of the PV door can thus vary according to the needs. As illustrated in FIGS. 2 to 4, this AR shaft has a first end provided with a second transfer gear PT1 which meshes with the first transfer gear PT1 and a second end which is adapted to be coupled to the lock SR in order to cause its actuation when it is rotated. Note that in the embodiment shown in non-limiting manner in Figures 1 to 5 the second end of the AR shaft is coupled to the lock SR indirectly via an output pinion PS which is itself coupled to the lock SR via a second axis A2. More specifically, the second end of the AR shaft is provided with a third transfer gear PT3 which meshes the output gear PS, and the second axis A2 is coupled to the lock SR to actuate the latter SR when is rotated by the output gear PS. In this case, the output gear PS is preferentially part of the interface device D. The second axis A2 has a first end which is intended to be introduced into an element of the lock mechanism SR. For example, this first end may have a cylindrical shape having a polygon-shaped section (for example a hexagon) and the element of the lock SR may comprise a housing of shape homologous to this section. Furthermore, the second axis A2 has a second end which is here intended to be introduced into a housing of the output gear PS.

For example, this second end may have a cylindrical shape having a polygon-shaped section (for example a hexagon) and the output pinion PS may comprise a housing of shape homologous to this section. Note that the second axis A2 may be part of the interface device D. But this is not mandatory. It can indeed be part of the mechanism of the lock SR. It will also be noted that the AR shaft, the second transfer gear PT2 and the possible third transfer gear PT3 can be part of the same one-piece part. But this is not obligatory. The second transfer gear PT2 and the possible third transfer pinion PT3 could indeed be fixedly attached to the ends of the AR shaft. An alternative embodiment without third transfer pinion PT3 and without output pinion PS may be considered. Indeed, the second end of the AR shaft could be adapted so as to be directly coupled to the mechanism of the lock SR. It will also be appreciated that the interface device D may, at least in some embodiments, be advantageously used with a commercial (i.e. unmodified) lock and / or a commercial lock (this is ie unmodified).

It will also be noted, as shown in non-limiting manner in FIG. 5, that the interface device D may comprise a BT protection (or burglar-proof) housing in which the first R1 and second R2 wheels are installed, the AR shaft, the first PT1 and second PT2 transfer gears, the possible third PT3 transfer gear, each CBi cable, and the possible PS output gear. Moreover, as illustrated without limitation in FIG. 5, this housing BT may optionally and advantageously comprise guides GC intended to guide the sliding of the cables Ci, and thus guarantee the permanence of their relative position with respect to the wheels R1 and R2, even in case of steep inclination of their PV door. In FIG. 5, the LV housing comprises a wall provided with an opening facing the CBi cables, but this wall could be completely closed. Thanks to such a housing BT, the various components of the interface device D can be precisely positioned relative to each other and are effectively protected against break-ins. In addition, the interface device D can advantageously be installed in the box CP of the PV door before the lock VR is installed. It will also be noted that at least some of the pinions (PT1, PT2, PT3 and PS) may optionally be arranged in such a way as to offer different reduction ratios in pairs. When a key actuates the mechanism of the lock VR in a first direction, for example associated with an unlocking, this rotates the first axis A1, which in turn rotates the first wheel R1. The CBi cables are then driven, which causes the rotation drive of the second wheel R1 and therefore the first transfer pinion PT1 coupled to it in rotation. The first transfer pinion PT1 then rotates the second transfer pinion PT2, which causes the rotation drive of the AR shaft and therefore the third PT3 transfer pinion coupled to it in rotation. The third transfer pinion PT3 then rotates the output pinion PS, which causes the rotation drive of the second axis A2 and thus the actuation of the mechanism of the lock SR. It will be understood that actuation of the key in a second direction, opposite the first, will provide the opposite effect, for example locking.

The invention offers several advantages, among which: a very small distance between the rear edge of the window and the rear wall of the door casing, a possibility of total recovery of the lock by the window through an adaptation of the diameter different gears, - a lack of space variation of the various components of the interface device during the actuation phases, - a very limited deformation of the shaft which prevents the occurrence of failures, - a very limited noise generation in the presence of vibrations and during door closures, due to the use of a bypass shaft and not a rod, the coupling to a lock and a lock without modification of the latter. The invention is not limited to the above-described interface device, locking system, vehicle door, and vehicle embodiments, by way of example only, but encompasses all variants that may consider those skilled in the art within the scope of the claims below.
