More specifically, the present invention relates to a locking member of a wheelhouse comprising at least one crank and at least one connecting rod in a transport position. The present invention also relates to a wheelhouse subassembly and a wheelhouse having such a locking member, and also to a method of setting up such a locking member on a wheelhouse.

Motor vehicle wiper mechanism linkages are articulated systems in different locations. This articulation is necessary for the proper operation of the wiper system once the wheelhouse installed on the motor vehicle. However, such articulation presents problems in particular for the transport of this wheelhouse and for the installation thereof on the motor vehicle. Thus, it is necessary to limit the degrees of freedom of the wheelhouse both during transport and during installation.

Knocking elements are known for connecting the connecting rod to bearings for fixing the wheelhouse on the motor vehicle so that the wheelhouse is in a transport position. The blocking elements known in the state of the art can be in various forms, such as in the form of a clamp, to ensure the locking of this linkage in a transport position and installation is ie a position in which any movement of a landing of the wheelhouse relative to the connecting rod is prevented.

However, these locking elements described in this document are disposable and are removed, for example by cutting after installation of the wheelhouse on the motor vehicle. Thus, it is necessary to use tools, usually sharp, in order to release the wheelhouse. Moreover, such locking elements generate debris that will need to be processed later, which generates additional costs.

The following achievements are examples. Although the description refers to one or more embodiments, this does not necessarily mean that each reference relates to the same embodiment, or that the features apply only to a single embodiment. Simple features of different embodiments may also be combined or interchanged to provide other embodiments.

In the following description, reference is made to a first and second side of the wheelhouse, at first and second ends of the crank, at a first and a second side of the crank, at a first and a second second surfaces of the connecting rod, at first and second growths, first and second housings, and first and second wheelhouse subassemblies. It is a simple indexing to differentiate and name close but not identical elements. This indexing does not imply a priority of one element with respect to another and it is easy to interchange such denominations without departing from the scope of the present description. This indexing does not imply either an order in time for example to appreciate the arrangement of the wheelhouse on the motor vehicle, its operation, or its installation, or to appreciate the shape of the locking member or its installation on the wheelhouse to maintain the wheelhouse in its transport position.

In the following description, the term "transport position" is understood to mean a position in which at least one end of the connecting rod and a crank to which this end of the connecting rod is connected form a minimum angle, more precisely at least this end. the rod is in a position close to the bearing on which the crank is hinged so that the wheelhouse has a minimum space when it is in its transport position.

Referring to Figures 1 to 4, there is shown a wheelhouse 7 of a wiper mechanism of a motor vehicle. The wheelhouse 7 comprises a first subassembly 9 (better visible in FIGS. 2 and 3), a second subassembly 9 ', and in addition a motor 71 configured to allow the translational movement of a connecting rod 3 connecting the first 9 and second 9 'subsets.

The first 9 and second 9 'subassemblies each comprise a bearing 91 and a crank 5 articulated on the bearing 91.

The crank 5 has a first end 53 connected to the bearing 91, by a pivot connection for example, and a second end 55 carrying a ball joint connection 57. On the other hand, one end of the connecting rod 3 is connected to this ball joint connection 57. in order to allow articulation of the connecting rod 3 on this ball joint 57. Furthermore, the crank 5 has a first face 5a opposite to a second face 5b disposed facing the connecting rod 3. Similarly, the rod 3 presents a first surface 3a opposed to a second surface 3b disposed facing the crank 5.

When the linkage 7 is in the transport position, the relative position of at least one end of the connecting rod 3 is kept fixed with respect to the crank 5 of the first 9 or the second 9 'subassembly with the aid of a blocking member 1.

With reference to FIG. 4, the locking member 1 is represented in more detail. The locking member 1 comprises a first protrusion 11, a second protrusion 13, and an elastic axis 15 connecting the first 11 and the second 13 excrescences between them. This locking member 1 cooperates with a first housing 51 formed in the crank 5 and a second housing 31 (visible in Figure 3) formed in the connecting rod 3 to maintain the first subassembly 9 for example in the transport position of the wheelhouse 7. More particularly, the elastic shaft 15 is arranged to pass through the first 51 and second 31 housings. As can be seen in FIG. 3, the first housing 51 is disposed near the second end 55 of the crank 5 and the second housing 31 is disposed at the connecting rod 3 near the ball joint 57.

The first 51 and second 31 housings are arranged opposite one another relative to the central axis A (visible in particular in Figure 2) of the rod 3 when the wheelhouse 7 is in the transport position . In fact, with such an arrangement of the first 51 and second 31 housings, the locking member 1 tends to bring the crank 5 and the link 3 together by the elastic effect and maintains the distance between these first 51 and second fixed housing 31, so as to reversibly freeze the relative position of the connecting rod 3 relative to the first end 53 of the crank 5.

Furthermore, as can be seen in FIG. 3, the first housing 51 and / or the second housing 31 have a narrowed opening 58 which has two chamfers 60 converging towards the center of the crank 5 thus defining a convergent channel for insertion of the blocking member 1 and more particularly of the elastic axis 15. The convergent channel opens onto a circular opening 59. Thus, the elastic axis 15 of the locking member 1 can be locked inside this circular opening 59 The locking of the elastic shaft 15 inside the circular opening 59 allows the locking member 1 to remain on the wheelhouse 7 after release of the first subassembly 9 for example, which allows to reduce the waste generated during the installation of this wheelhouse 7 on the motor vehicle. On the other hand, one of the first 51 or second housing 31 has a U-shaped slot 33 (visible in FIG. 3) intended to cooperate with the elastic axis 15 of the locking member 1 in a reversible manner so that the locking of the wheelhouse 7 in the transport position is reversible.

According to the particular embodiment of Figure 1, the wheelhouse 7 has a first side 7a and a second side 7b. According to this embodiment, the first subassembly 9 is disposed on the first side 7a and the second subassembly 9 'is disposed on the second side 7b. The motor 71 is installed on the second side 7b of the wheelhouse 7. Furthermore, only the first subassembly 9 comprising the locking member 1 is disposed on the first side 7a. According to this embodiment, an arrow M indicates the movement of the first end 53 of the crank 5 towards the connecting rod 3 during the introduction of the locking member 1. The second side 7b of the wheelhouse 7 generally corresponds to the the driver's side of the motor vehicle once the wheelhouse 7 installed on the motor vehicle. Alternatively, the second side 7b may correspond to the passenger side of the motor vehicle once the wheelhouse 7 installed thereon.

According to another embodiment not shown here, the first 9 and second 9 'subassemblies each have a locking member 1 maintaining the relative position of each end of the rod 3 fixed by the first end 53 of the crank 5 scope by the first 9 and second 9 'subassemblies. Thus, the first side 7a and the second side 7b of the wheelhouse 7 are locked in the transport position.

According to yet another embodiment not shown here, only the second subassembly 9 'has the locking member 1. Thus, only the second side 7b of the wheelhouse 7 is locked in the transport position.

Advantageously, the blocking of the articulation of the connecting rod 3 on the ball joint 57 facilitates the transport of this linkage 7 by removing degrees of freedom of movement of certain parts of the wheelhouse 7 and by locking the linkage 7 in a position having a minimal bulk. Moreover, the locking of this articulation also makes it easier to install this wheelhouse 7 on the motor vehicle by blocking in particular the articulation of the connecting rod 3 on at least one of the ball joints 57 carried by each of the cranks 5 of the first 9 and second 9 'subsets.

In the case where the linkage 7 has a locking member 1 disposed at each end of the connecting rod 3, the second subassembly 9 'also has a narrowed opening 58 and a slot 33 arranged for one or the other on the crank 5 or on the rod 3 as described above.

Referring again to Figure 4 showing the locking member 1 in detail, the first 11 and second 13 protuberances are configured to ensure the holding in place of the locking member 1 when it ensures the blocking of the connecting rod 3 and crank 5 in the transport position. In order to facilitate the installation of the locking member 1 and the release of the linkage 7, at least one of the protuberances 11, 13 has a height H less than the spacing H 'between the crank 5 and the connecting rod 3 (FIG. visible in Figure 6).

According to the particular embodiment of FIG. 4, the first 11 and second 13 protuberances are made of at least one elastic material. Advantageously, in order to improve the resistance of the locking member 1 to the various stresses, in particular of torsion and shear, which it can undergo and also in order to accelerate the manufacturing process of this locking member 1, the first 11 and second 13 protuberances and the elastic axis 15 are made of material. Furthermore, the locking member 1 is ideally made of rubber because this material is inexpensive and has elasticity and strength properties, including tearing, in line with the use of the locking member 1.

According to another embodiment not shown here, the first 11 and second 13 protrusions are made of a rigid material, that is to say not having elastic properties.

According to the particular embodiment of Figure 4, the elastic axis 15 has a cylindrical shape. The use of a cylindrical shape for the elastic axis 15 facilitates its insertion inside the narrowed opening 58 and a good cooperation with the circular opening 59. Moreover, the use of a shape cylindrical for the elastic axis 15 also facilitates the cooperation of this elastic axis 15 with the slot 33. According to the particular embodiment of Figure 3, to maintain the locking member 1 inside the circular opening 59, the narrowed opening 58 is smaller than the diameter D 'of the elastic axis 15 of the locking member 1. Moreover, the circular opening 59 has a diameter at least equal to the diameter D of the axis elastic 15, but less than a diagonal of the protrusion 11, 13 carrying the end of the elastic axis 15 cooperating with the circular opening 59 so that this protrusion 11, 13 can not cross this e circular opening 59.

Furthermore, according to the particular embodiment of Figure 4, at least one of the first 11 and second 13 protuberances has a cylindrical shape. According to this particular embodiment, the first 11 and second 13 protuberances have a cylindrical shape. Advantageously, at least one of the protuberances 11, 13, or both, has at least one of the height H or the diameter D less than the spacing H '(visible in FIG. 6) between the crank 5 and the connecting rod 3 Using a height H or a diameter D smaller than the spacing H 'between the connecting rod 3 and the crank 5 makes it easier to install the locking member 1 on the wheelhouse 7 when the latter it is in transport position. Furthermore, the release of the wheelhouse 7 can be facilitated by the use of such dimensions for the height H or the diameter D because the first 11 or second 13 protrusion can pass between the connecting rod 3 and the crank 5 during the release of the wheelhouse 7 as shown with reference to Figure 6.

Referring to Figures 5A and 5B, there is illustrated a method of placing the locking member 1 on the first subassembly 9 of Figure 3 to lock the wheelhouse 7 in the transport position.

With reference to FIG. 5A, the method comprises a step a of insertion of the elastic axis 15 into the first housing 51 in order to install the locking member 1 at the level of the crank 5.

The method then implements a step b of rotation of the connecting rod 3 around the ball joint 57 in order to place the linkage 7 in the transport position, then a step c of passage of the second protrusion 13 between the crank 5 and the connecting rod 3. According to one variant, these two steps b, c can be reversed. According to this variant, a traction step on the second protrusion 13 along the crank 5 is performed in order to bring the first protrusion 11 into contact with a first surface 5a of the crank 5 disposed opposite a second 5b facing opposite the rod 3. The rod 3 is then rotated to be placed in the transport position maintaining traction on the second protrusion 13.

With reference to FIG. 5B, the method then comprises a step d of insertion of the elastic axis 15 into the second housing 31 in order to maintain the relative position of the rod 3 fixed with respect to the first end 53 of the crank 5 when the wheelhouse 7 is in the transport position. When the wheelhouse 7 is locked in the transport position, the first protrusion 11 protrudes from the crank 5 and is in contact with the first face 5a of the crank 5 opposite the second face 5b disposed opposite the rod 3. By elsewhere, the second protrusion 13 protrudes from the connecting rod 3 and is in contact with the first surface 3a of the connecting rod 3 opposite the second surface 3b disposed facing the crank 5. The linkage 7 is held in the transport position by means of to the elastic stress exerted by the elastic axis 15 between the first 51 and second 31 housings.

Thus, the installation of the locking member 1 to maintain the wheelhouse 7 in the transport position is possible without requiring the use of tools.

Referring to Figure 6, there is shown the first subassembly 9 of the wheelhouse 7 after the rod 3 released. To release the linkage 7, the locking member 1 is removed from the second housing 31 by pressure on the second protrusion 13 to allow the output of the elastic axis 15 of the second housing 31. Following this output of the second protrusion 13, it comes into contact with the second face 5b of the crank 5. This displacement of the second protrusion 13 is possible due to the elastic return imposed by the elastic axis 15 in response to the extension undergone during the step of pushing on the second protrusion 13 to extract it from the second housing 31. Furthermore, the operator carrying out the installation operation of the wheelhouse 7 on the motor vehicle can also fire on the first protrusion 11 in order to bring the second protrusion 13 into contact with the second face 5b of the crank 5 if this is necessary. Preferably, the wheelhouse 7 is released from the transport position once it is installed on the motor vehicle. In addition, the locking member 1 remains in the first housing 51, and more precisely at the circular opening 59 because the narrowed opening 58 prevents the natural passage of the elastic axis 15 and therefore the exit of the blocking member 1.

Thus, the release of the wheelhouse 7 is possible in a simple manner and without requiring the use of tools. Indeed, this release is only by pushing on the second protrusion 13 to bring out the second protrusion 13 of the second housing 31. Moreover, this release is simple and easy to implement.

Referring to Figure 7, there is shown partially the wheelhouse 7 installed on the motor vehicle, and more particularly the first side 7a of the wheelhouse 7. According to the particular embodiment of Figure 7, the wheelhouse 7 is fixed on the motor vehicle using fixing screws 73 configured to secure the bearing 91, and in particular a plate 93 carried by the bearing 91, to an element of the motor vehicle. Advantageously, the locking member 1 remains on the linkage 7 at the first housing 51 of the crank 5 after release thereof. Thus, reuse of this locking member 1 is possible if it is necessary to lock the wheelhouse 7 in the transport position later. Furthermore, the fact that the locking member 1 remains on the wheelhouse 7 after release thereof limits the waste to be treated because of the installation of this wheelhouse 7 on the motor vehicle. The fact that the locking member 1 remains on the crank 5 following the release of the wheelhouse 7 does not affect the operation of this linkage 7 because the second protrusion 13 has a height H less than the spacing H 'between the connecting rod 3 and the crank 5 on the one hand, and the wheelhouse 7 does not pass through its transport position during its operation on the other hand.

According to a variant not shown here, the locking member 1 can be removed from the crank 5 after release of the linkage 7. This withdrawal of the locking element 1 is achieved by extraction of the elastic axis 15 of the first housing 51 of the crank 5, and more precisely of the circular opening 59 of the first housing 51.

The embodiments described above are examples provided for illustrative and not limiting. Indeed, it is quite possible for those skilled in the art to adapt the geometric shape or the dimensions of the first 11 and second 13 protrusions and the elastic axis 15 of the locking member 1 without leaving of the present description. Moreover, one skilled in the art can quite adapt the shape of the first 51 and second 31 housing to improve their cooperation with the elastic axis 15 without departing from the scope of this description.

Thus, the reversible holding in place in a transport position of a wheelhouse 7 is possible thanks to the locking member 1 described above. Advantageously, the locking member 1 is installed on the wheelhouse 7 without requiring the use of tools and the release of the wheelhouse 7 is also possible without the use of tools. Furthermore, the use of such a locking member 1 limits the waste to be treated because it remains on the wheelhouse 7 after installation on the motor vehicle. On the other hand, such a locking member 1 may allow to lock again the wheelhouse 7 in the transport position if necessary later.
