In the field of vehicle manufacturing cars, it is known to use a piece of plastic material to keep a vehicle vehicle swing in a position close to its closed position, in order to allow a transport of the vehicle on the manufacturing chain as well as the lining of the external parts of the body. When should be coated the inside of the box and the vehicle's hinges, these hinges are manipulated to allow access to the volume vehicle interior Plastic parts must allow to immobilize the hinges in the proximity of their position of closing on the box, that is to say in a configuration in which the outer face of the swinging flush with the outer surface of the box with a difference of a few millimeters. A piece of the type cited is known, for example, by the document FR-A-2,773,838.

The swinging of motor vehicles are intended to be equipped with attached materials, such as crystals, crystal motorization systems, some speakers, handles, and interior linings. The articulation hinges of the different hinges on the box of the vehicle are sized according to the weight of each swing equipped with these materials. Now the pieces of separation mentioned above are used when they take place vehicle manufacturing stages in which the hinges do not they are equipped with these materials, in what is a defect alignment between the area provided on the reception box of the locksmith and the housing provided in the swing for the lock placement. This results in defects of alignment of the swing with respect to the box, particularly when Vehicle painting operations take place.

Thus, with a prior art device the piece of plastic material can be supported, by an area angled, against the edge of the housing provided on the swing which induces an impact on this edge when the operator or a manipulator robot pushes the swing towards its position of almost closing. This has the consequence that this edge can be marked or damaged, which creates an appearance defect in the vehicle, it even hinders the further placement of the lock in your accommodation or favors corrosion.

An increase in manufacturing tolerances of the known parts do not allow to solve this problem since the dispersion of swing positions can be relatively important and since said piece must be able to be mounted on the two sides of a vehicle.

It is these inconveniences that he intends most particularly avoiding the invention by proposing a device for provisional interlocking that does not run the risk of damaging the swing in its contact area with the device.

In this essentiality, the invention relates to a device for provisional separation and interlocking of a swing over a motor vehicle box, allowing this device keep this swing in the proximity of a position closing with respect to the box and comprising a body intended to be immobilized on this box, at the level of an area for fixing a strike, while this device is suitable to interact by means of a peak with an edge of a housing of receiving a lock in the swing in order to interlock this swing in the position mentioned. This device is characterized in that the body is equipped with a mobile skate with with respect to the body, this skate being able to go to support against an edge of the mentioned housing.

The position of this skate with respect to this body depends on the support conditions of the skate against the edge aforementioned. Thus, a self-positioning of the skate with respect to the main body of the device, which allows to avoid a support too marked of this skate against the edge of the housing provided on the swing. In other words, the movements of the skate allow to adapt the location of the contact area between the device and the swing, depending on the height of the swing Regarding the box.

According to some advantageous aspects but not mandatory of the invention, the device incorporates one or more of the following characteristics:

The device 10 shown in the figures comprises a monobloc body 11 of plastic material, for example made of high temperature resistant 6-6 polyamide such as those to which a vehicle box is exposed when cooking a layer of paint takes place.

The body 11 comprises a sole 12 from which a pivot 13 extends to penetrate a hole O provided in a zone Z of the vehicle's C-box. The sole 12 is equipped, on its face 12, to be turned towards the case C, of protuberances 14 which allow a space for the cataphoresis bath between the sole 12 and the case C.

The sole 12 is also perforated by a hole 15 in which a screw 16 is provided which is attached to the sole 12 thanks to breakable bridges 17.

Screw 16 is intended to be inserted in a threaded hole T made in zone Z.

Thus, pivot 13 and screw 16 allow immobilize the body 11 of the device 10 over the zone Z of the C box of a vehicle.

The body 11 also comprises a structure in arc shape 18 from which a tongue 19 extends provided with a peak 20 intended to cooperate with an edge of a accommodation provided at a door P of the vehicle.

The tongue 19 and the beak 20 allow the interlocking of the P gate in a configuration close to the closed position on box C. This configuration is used for the application of coating products on the exterior surface of the door P.

The tongue 19 is made of spring steel and is overmoulded inside the arc 18 of the body 11, as it stands out more particularly in Figure 8. The tongue 9 is thus immobilized by its lower end 19 b in the arc 18.

In the vicinity of its upper end 19 c , the tongue 19 is provided with a hole 19 a into which a bead 20 a of the tip 20 is inserted. In practice, the tip 20 is overmoulded on the tongue 19, which ensures his firm immobilization over
is.

It is noted that the overmolding of the arc 18 around the end 19 b of the tongue 19 and of the heel 20 in the opening 19 a can take place simultaneously when the molding of the device 10 as a whole takes place, the tongue 19 being then positioned correctly in the corresponding mold.

The use of a different material to make the tongue 19 allows to choose this material mainly depending on the flexibility sought for this tab, being able to this flexibility be variable depending on the type of body to equip and, in particular, the inertia of the hinges to be interlocked provisionally. Thus, the choice of some types of steel allows obtain an important stiffness of the tongue 19 or, by the On the contrary, great flexibility. This stiffness characteristic or of flexibility of the tongue 19 does not evolve depending on the time, even if the device 10 as a whole is subjected to a temperature of the order of 180ºC, when it passes through a tunnel of drying, and 80 ° C when you must work to interlock the swinging

According to an unrepresented variant of the invention, it is possible to provide that the tongue 19 is made in a composite material comprising glass fibers that are also stable at the expected temperatures.

According to a variant of the invention, the device 10 is made entirely of plastic material and monobloc, the tongue 10 joining the body 11 to the peak 20 then of plastic material. This variant is particularly attractive in the economic plane.

Door P can be released with respect to the device 10 exerting on the tongue an effort E of displacement of peak 20, tending this effort to push the peak 20 to the left in figure 3.

The arc 18 is extended by a shoulder 22 in the which is a section opening 23 made globally rectangular.

The shoulder 22 is joined by two bridges breakable, 24 and 25, to a skate or stirrup 30 globally in the form of OR.

The skate 30 comprises a first branch 31 whose section is such that it can penetrate and slide into opening 23. The skate 31 also comprises a second branch 32 attached to branch 31 for a background 33.

The branch 31 is provided with an end nose 34 which forms a projection in the direction of the arc 18. This nose has a surface 34 a globally inclined with respect to the longitudinal axis XX 'of the branch 31 of a second surface 34 b globally perpendicular to this axis .

The geometry of the nose 34 is such that it does not oppose at the introduction of the branch 31 in the opening 23, in the sense of the arrow F_ {3} in figure 1, but that opposes its extraction in the direction of arrow F_ {4} in figure 7.

In practice, bridges 24 and 25 are broken when an effort F5 of introduction of branch 31 into opening 23.

The branch 31 is mechanically braked inside the opening 23 thanks to two ribs 35 and 35 'which can be described as "moldings" and which are compressed when the introduction of the branch 31 takes place in the opening 23. In other terms , the ribs 35 and 35 'substantially increase the coefficient of friction of the branch 31 in the opening 23 so that, once the skate 30 has been positioned with respect to the shoulder 22 thanks to the positioning effort F 5, it has tendency to remain in position without sliding with respect to the longitudinal axis
YY 'of the opening 23 which is then confused with the X-X axis'.

Other braking means of branch 31 in the opening 23 may be provided, such as teeth or a dimensioning adapted from the section of the branch 31 with respect to the interior dimensions of the opening 23.

The branch 32 is provided with an external surface 32 a globally in the form of a cylinder portion of which R the radius of curvature is noted. This radius R is relatively large with respect to the other radii of curvature of the surfaces of the device 10, so that the surface 32 can deliver a F_ {6} stress applied substantially in a direction perpendicular to the axis XX ' .

Thus, as depicted in Figure 6, when the skate 30 comes into contact with the edge 51 of a housing 50 provided in the door P for the placement of a lock at a later stage of vehicle manufacturing, the effort F_ {6} can be distributed over the edge 51, without risk of localized deformation of this edge. The possibility of sliding of the skate 30 with respect to the body 11, possibility which is represented by a double arrow F_ {3} -F_ {4}, allows to adjust with a good precision the position of the skate 30 with respect to the geometry and a exact position of bottom 51a of edge 51, taking into account door positioning tolerances P with respect to the box C.

As depicted in Figures 1 to 4, the device 10 can be molded in one piece in material plastic being elements 11 and 30 joined by bridges 24 and 25, allowing for easy manipulation of the device before have the operator insert the branch 31 of the skate 30 into the opening 23 thanks to the effort F_ {5}. When this has been done introduction, bridges 24 and 25 are no longer necessary since the skate 30 cannot be removed from opening 23, taking into account the geometry of the nose 34.

As highlighted in Figure 7, the position of the skate 30 with respect to the body 11 is adjustable parallel to the direction of the X-X 'axis, with a stroke d . The stroke d is chosen based on the usual variations in the height of the door P with respect to the box C.

The final sliding of the branch 31 along the axis Y-Y 'of the opening 23 takes place when the door P reaches its closed position, this slip being obtained automatically thanks to the transfer of kinetic energy from the door P.
