Description

Opening control device for a door of a motor vehicle.

Technical field of the invention

The invention relates to an opening control device for a door of a motor vehicle. The invention also relates to a locking system comprising such an opening control device. The invention also relates to a motor vehicle comprising such an opening control device and/or such a locking system. The invention finally relates to a method for assembling such an opening control device to a door of a motor vehicle.

State of the prior art

Motor vehicles, and in particular commercial vehicles, are generally equipped with a door locking system comprising, on the one hand, an opening control device and, on the other hand, a lock connected to the opening control device by a rod or cable. The opening control device comprises a support, or module, by means of which it is fixed to a door element such as a sheet metal panel. The opening control device also comprises an actuating handle articulated with the support and accommodates a lock in an opening of the support. The actuating handle and the bolt are mechanically connected to the lock via the rod or the cable. The lock can cooperate with a key to establish, or on the contrary interrupt, the effect of a movement of the actuating handle on the lock.

Such locking systems provide insufficient security. In particular, thieves can manage to manipulate the lock integrated into the opening control device by using various tools, such as screwdrivers. By rattling the bolt, forces are transmitted to the support through which the opening control device is fixed to the door. When the rod reaches a sufficient range of movement, the lock can be operated and the door can be opened. Such a break-in can be carried out in a sometimes very short time.

Furthermore, the locking systems known from the state of the art can also have quality defects. Repeated manipulations of the actuating handle and/or the lock, as well as the vibrations of the vehicle can lead to the loss of parts and therefore to the failure of the locking system.

Finally, the locking systems with integrated lock known from the state of the art are complex to assemble inside a door of a vehicle. The operations necessary for fixing it are sometimes carried out incompletely. In particular, the operation of fixing the lock to the support of the opening control device is sometimes carried out incompletely. When this is the case, the locking system can be forced even faster by a thief.

detailed description

There schematically illustrates a motor vehicle 1 equipped with a door 2 and a locking system 3 of the door according to one embodiment of the invention. The vehicle 1 can be of any kind. In particular, it may for example be a private vehicle, a utility vehicle, a truck or a bus. The door 2, or opening 2, or even door 2, is an element which makes it possible to open or close access to the interior of the vehicle 1, in particular to a loading space or to a passenger compartment of the vehicle. The door 2 comprises a door element, in particular a panel 4 extending in a main plane. This panel 4 can be hinged in rotation with respect to a body of the vehicle, for example via hinges 5. It preferably comprises a cut and shaped sheet metal plate. The door element may for example be a bodywork element of the vehicle and/or a box forming a rigid structure of the door.

In this document, the X axis refers to the longitudinal axis of a vehicle. In forward gear and in a straight line, the vehicle progresses from the rear to the front in a direction parallel to its longitudinal axis X. The X axis is oriented from the front to the rear of the vehicle, i.e. i.e. in reverse direction. The Y axis designates the transverse axis of the vehicle. The Y axis is oriented from left to right, with left and right defined from the perspective of a driver of the vehicle. The Z axis refers to the axis perpendicular to the X axis and the Y axis. The Z axis is a vertical axis when the vehicle is resting on horizontal ground. The Z axis is oriented from bottom to top. The X, Y and Z axes form an orthogonal frame. This same mark, defined by reference to a vehicle, will also be used for a locking system or an opening control device, even considered outside a vehicle, since they are intended for mounting according to a specific orientation on a vehicle. Moreover, it is considered that the vehicle 1 rests on a horizontal ground.

According to the embodiment presented, the door 2 is a rear door of a commercial vehicle. The door is hinged around an axis parallel to the vertical axis Z. Alternatively, the door 2 could be any opening of a vehicle sensitive to burglary, for example a side door. Door 2 could also be a sliding door.

The locking system 3 comprises an opening control device 10, a lock 6, a lock 7 and a rod 8. The lock 7 is fixed to the panel 4 of the door 2. It comprises a bolt cooperating with a striker plate 9 integral of the body or secured to a second door of the vehicle to lock the door 2 in the closed position. The rod 8 can be an elongated element, possibly locally bent, extending mainly parallel to the vertical axis Z. It is able to transmit to the lock 7 a movement exerted by the bolt 6. Alternatively, the rod 8 could be replaced by a cable. The opening control device 10 is mechanically connected to the lock via the bolt 6 and the rod 8. The lock 7 and the opening control device are therefore two separate items of equipment for the door. According to the embodiment presented on the , the lock 7 is positioned vertically above the opening control device 10 but alternatively it could be positioned in any other place of the door 2.

The opening control device 10 comprises a support 11, an actuating handle 13 and a member 20 for holding the lock. The control device is illustrated in Figures 2, 3 and 4. It is shown in a plane parallel to the transverse axis Y and to the vertical axis Z in view from inside the vehicle to the outside. The panel 4, which extends perpendicular to the longitudinal axis X, is made invisible. Only a side C1 control of the panel is made visible. Field C1 delimits the edge of the panel along which the opening control device 10 is arranged. Field C1 extends in a plane substantially perpendicular to the main plane in which the panel extends. In this case the field C1 extends in a plane perpendicular to the transverse axis Y. The field C1 can for example be formed by a fold substantially at 90° to a side edge of the panel 4.

The support 11, or "module 11", is an element fixed to the panel 4 of the door 2. It can comprise a body, advantageously made of plastic, in which are provided means for connecting to the panel 4. These connecting means can be for example clips and/or openings. These openings, possibly threaded, can be intended to cooperate with fastening members such as screws, or even rivets. The support 11 notably supports the latch 6 and the actuating handle 13. It notably comprises means for articulating the actuating handle 13. It can also comprise means of mechanical connection between the actuating handle 13 and the lock. The support 11 can furthermore also comprise return means to return the actuating handle 13 to a retracted position after it has been manipulated. The rotation of the holding member 20 locks the lock (mounted from the outside) and completes the attachment of the assembly to the panel 4.

The support 11 comprises a first opening O1 arranged around a main axis X1, parallel to the longitudinal axis X. The holding member 20 comprises a second opening O2 arranged around said main axis X1. The openings O1 and O2 can have an at least roughly circular shape. The openings O1 and O2 are concentric, that is to say that their center coincides along a projection parallel to the longitudinal axis X.

The holding member 20 is positioned forward relative to the support 11. It is therefore linked to the panel 4 of the door via the support 11. The holding member 20 comprises a ring 30 and a slider 40 The ring 30 is articulated in rotation with respect to the support 11 around the main axis X1. Said second opening O2 is formed in the ring 30. The ring 30 is rotatable relative to the support 11 between a first position (illustrated in the ) and a second position (shown in Figures 3 and 4).

The first position is a position in which the lock 6 is free to be inserted through the first opening O1 and the second opening O2. The second position of the ring is a position in which the lock 6 previously inserted through the first opening O1 and the second opening O2 is locked in position.

The first position of the ring can be separate from the second position of the ring by an angle comprised between 5° and 120°, in particular comprised between 10° and 60°. In particular, approximately one-eighth of a turn, that is to say approximately 45°, can separate the first position from the second position of the ring.

The ring and/or the support may comprise retaining means configured to retain the ring relative to the support along the longitudinal axis X when the ring is in its first position and/or in its second position. Thus, the opening control device 10 can be made available as a single piece in the workshop in which it is intended to be assembled with the door element.

The rotation of the ring relative to the support between its first and its second position may optionally be accompanied by a translational movement of the ring along the longitudinal axis X, in particular thanks to ramps provided at an interface between the support and the ring.

The lock, or barrel, is housed inside the first opening O1 and the second opening O2. It itself comprises an opening for a key extending substantially along the main axis X1.

On the one hand, the panel 4 comprises a third opening coinciding with the first opening O1 and with the second opening O2. On the other hand, the panel 4 can comprise a fourth opening through which passes all or part of the actuating handle and/or the means of articulation of the actuating handle. The third opening and the fourth opening can optionally form one and the same opening.

The opening control device 10 differs from a so-called "full skin lock" locking system in which the lock is fixed directly through the panel 4 of the door independently of the opening control. In the present invention, the lock is fixed to the door via a support combining different functions, in particular that of supporting an actuating handle. Such an architecture allows easy assembly of the locking system on the door, in a limited number of operations.

The actuating handle 13 can be articulated with respect to the support according to a connection in rotation around an axis Z1 parallel to the vertical axis Z, that is to say an axis parallel to the axis around which the door. Thus, a pulling movement on the actuating handle 13 stresses both the mechanism linking the handle to the lock to unlock the lock and participates in the effort required to manipulate the door from its closed position to its open position. Such an actuating handle, called "fridge type" therefore allows efficient and rapid opening of the door.

The slider 40 is connected to the ring according to a sliding connection parallel to a sliding axis A1. The slider is movable between a first position (illustrated in the ) and a second position (shown in the ). When it is in its second position, the slider 40 is in abutment against the field C1. The sliding axis A1 is substantially perpendicular to said main axis X1. In other words, the sliding axis A1 extends in a plane parallel to the transverse axis Y and the vertical axis Z, independently of the position of the ring 30. As illustrated in the , when the ring is in its first position, the sliding axis A1 can form with the transverse axis Y and with the vertical axis Z an angle of approximately 45°. As illustrated on the , when the ring is in its second position, the sliding axis A1 may be substantially parallel to the transverse axis Y, that is to say perpendicular to the plane in which the field C1 extends. The slider 40 can slide relative to the ring 30 independently of the position of the latter.

The rotation of the ring 30 between its first position and its second position and the translational movement of the slider 40 are carried out only during the assembly of the opening control device on the door of the vehicle, more particularly when the module 11 is already mounted on the door. The slider is intended to be fixed integrally to a door element when the ring is in its second position. In particular, the slider 40 comprises a threaded opening 41, extending substantially parallel to the sliding axis A1. As illustrated on the , the opening 41 cooperates with a screw 42 passing through an opening made through a field C1 of the door to lock the slider. During use of the vehicle, the ring and the slide therefore remain fixed in position relative to the door. As a variant, the slider could be fixed to the field C1 of the door by a fixing means other than a screw, for example by means of a rivet or even with any fixing means passing through the field C1 of the door.

The ring 30 comprises a central part 31, of at least roughly cylindrical shape, in which the second opening O2 is arranged. The ring 30 also includes an appendage 32 extending radially from the central part 31. Advantageously, the central part 31 and the appendage 32 form a single piece. The appendix 32 supports the slider 40. More particularly, the appendix 32 comprises a guide rail 33 and the slider comprises a groove 43 of a shape complementary to that of the guide rail 33 so as to form the sliding connection. The guide rail can integrate a means for retaining the slide along the longitudinal axis X. In particular, this retaining means can be formed by a section of the guide rail in the shape of a T or in the shape of a mushroom.

The guide rail can be arranged on a face of the appendage 32 facing the front of the vehicle. According to a variant embodiment, the slider could also be arranged on another face of the appendage, or even be arranged inside a housing formed in the appendix.

The ring 30 comprises a pusher 34 provided with a bearing surface allowing the ring to be pivoted from its first position to its second position. Pusher 34 extends substantially radially from central portion 31. Pusher 34 may extend from central portion 31 in a direction substantially opposite to the direction in which appendix 32 extends. It may comprise at its end 35 a blind cavity, for example in the form of a half-shell, intended to receive the tip of a tool. Pressing the tool on the end 35 makes it possible to exert a force parallel to the arrow F1 which tends to cause the ring to pivot towards its second position. Alternatively, the ring 30 could not include such a pusher. The appendage 32 advantageously comprises a second support surface 36, a support on the second support surface (oriented from right to left according to the point of view of the ) tending to cause the ring to pivot relative to the support from its first position to its second position. The appendix therefore fulfills a dual function of supporting the slider 40 and of bearing surface for pivoting the ring relative to the support 11.

The first and/or the second position of the ring 30 can be defined by conjugate abutment means B1, B2, B3, B4 arranged respectively on the ring and on the support. The abutment means B1 can cooperate with the abutment means B2 to define the first position of the ring. The abutment means B3 can cooperate with the abutment means B4 to define the second position of the ring. The stop means B2 and B4 can be provided on the pusher 34 as shown in the , or alternatively, be integrated into any other part of the ring. The stop means B1 and B3 can be integrated into the body of the support.

The amplitude of movement of the slider can be delimited by conjugate stop means B5, B6, B7, B8 arranged respectively on the slider and on the ring. The abutment means B5 can cooperate with the abutment means B6 to define the first position of the slider which can be a first extreme position of the slider. The abutment means B7 can cooperate with the abutment means B8 to define a second extreme position of the slider. Note that when the slider 40 is fixed against the field C1 of the panel, it adopts an intermediate position between the two end positions of the slider. The stop means B5, B6, B7 and B8 prevent accidental dissociation between the slider and the ring prior to their assembly on a door.

The support 11 and/or the ring 30 may comprise a fixing interface to hold the lock 6 in position. This fixing interface can be formed at the edges of the first opening O1 and/or of the second opening O2. In particular, ring 30 and/or support 20 may include notches 37 extending substantially radially relative to said main axis. These notches can cooperate with an outer contour of the lock 6 to hold it in position. The notches formed in the ring 30 are particularly clearly visible on the . Each notch 37 is associated with a ramp of annular profile having a section that changes with respect to its thickness. Each notch 37 is adapted to cooperate with an associated lug of the lock 6. During the assembly operation of the support 11 to the door panel 4, each lug of the lock 6 is moved along a ramp against which it slides in order to tighten the lock

The lock 6 comprises an inner part able to be pivoted around the main axis X1. This inner part is fixed to a camshaft 14 which is an element of the locking system 3. The camshaft 14 can be in the form of a plate at the end of which the rod support 15 is connected. The rod support 15 is attached to the threshing machine 14 according to a pivot connection. Thus, the rod remains substantially aligned parallel to the vertical axis Z when the harvester pivots around the main axis X1.

In addition, the ring 30 may comprise a projecting element (not visible in the figures) intended to face the panel 4. The projecting element is arranged so that, when the opening control device is made to rattle by the intermediary of the latch, the protruding element comes into contact with an inner face of the panel 4. Such a nodding may for example be an alternate bending movement by means of a screwdriver whose tip is inserted into the latch. The projecting element can for example take the form of a rib. It can extend parallel to the longitudinal axis X from the appendix 32 on a face of the appendage opposite to the face on which the slider 40 is mounted, that is to say a face of the appendage forming facing the panel 4. Thus, during an attempt to break into the vehicle, the panel can be scratched or marked by the support of the projecting element. These scratches or marks then provide evidence of the attempted break-in. Moreover, the more the support of the protruding element provides additional support for the opening control device on the panel 4, which further limits the amplitude of displacement for a given alternating bending force.

In the above description, the opening control device is equipped with a lock. Alternatively, the lock could not be present or be replaced by a false lock. Such an artifice makes it possible in particular to use the same opening control device to equip a door not provided with a lock, such as for example a passenger door, that is to say for example a door on the side opposite the driver or behind the driver.

To assemble the opening control device to a door element of the motor vehicle, one can proceed as follows. First, a door element is provided. The door element comprises in particular the panel 4 provided with the third opening. The opening control device 10 and the lock 6 are also provided. Advantageously, the opening control device 10 is in the form of a module whose elements are held together. In particular, the ring 30 is integral with the support 11 and is in its first position.

Then, the method comprises a step of positioning the opening control device against a first face of the door element. The support is positioned against an interior face of the panel. This can be fixed to the panel in particular by means of fixing clips and/or screws and/or rivets.

Then, the method comprises a step of inserting the lock through the first opening, the second opening and the third opening. In particular, the lock can be inserted longitudinally from the rear to the front.

Then, when the lock is in place, the method includes a ring rotation step relative to the support to its second position. According to the embodiment shown in the figures, the ring is therefore pivoted by approximately one-eighth of a turn counterclockwise. When the ring 30 is equipped with a pusher 34, this operation can be carried out by means of a tool passing through an opening provided in the field C1 of the door. The tip of the tool is then inserted into the blind opening formed at the end 35 of the pusher and a force substantially along the arrow F1 is applied. Then, the opening through which the tool was inserted to perform this operation can be plugged to guarantee the tightness of the door. As a variant, the rotation of the ring can be carried out manually by a force applied to the support surface 36, in particular by a force applied along the arrow F2. This avoids having to make a hole in the field of the door to pass a tool and avoids the operation of filling this hole to ensure the sealing of the door. Following the rotation of the ring 30, the lock is locked in position in the opening control device.

Then, the method comprises a step of moving the slider along the sliding connection and a step of fixing the slider to the door element. The slider can for example be pushed manually against field C1 of the door. Alternatively, it can advantageously be translated thanks to the reaction force produced by the screw 42 on the tapped opening 41 of the slider. Thus, the simple tightening of the fixing screw makes it possible on the one hand to translate the slider until it is in abutment against the field C1 of the door, and on the other hand to block the slider in position. The step of translating the slider and the step of fixing the slider can therefore be carried out simultaneously. The head of the screw 42 resting on the field of the door seals the door at the level of the opening through which the screw is inserted.

At the end of this assembly, the retaining member 20 is locked in position by a direct connection with the door, in particular with the field of the door. This avoids any loosening of the ring following a break-in attempt or as a result of vibrations to which the vehicle is subjected. The slide screwing operation is only possible if the ring is completely pivoted into its second position. The invention therefore also provides a means of checking the correct position of the holding member. This avoids partial rotation of the ring which could cause less robustness or early loosening.
