Description

Sliding vehicle door.

The present invention relates to a set sliding door, of the type indicated in the preamble of the claim 1. A set of this type is known from US-A-4,464,863.

It applies in particular to sliding doors of motor vehicles.

Stopping devices of sliding doors of motor vehicles. A device of this type is described in the document FR-A-2 763 026. The device is adapted to lock the door in its open position.

This device comprises a guide rail in which a sliding mobile car is guided. This car It comprises a wheel.

The detention device is provided with a ramp that is arranged on the rail. This one delimits a stop housing for the wheel and is articulated between a wheel passage position and a wheel lock position. The ramp is requested to its locked position by a block viscoelastic

A door equipped with a device of this type can be taken out of its open position by push towards its closed position. On this occasion, the wheel overcomes the ramp against the force exerted by the viscoelastic block.

Generally, detention devices these types are arranged at the top or bottom of the door, while a maneuvering handle is arranged in a middle part of the door.

Therefore, when the door is pushed towards its closing position, the reaction force between the shooter and the stop device creates a tilt pair of the door around an axis perpendicular to the plane of the door. This pair requests the car and leads to a risk of stalling the door. Therefore, the force necessary to take the door out Its opening position is important.

There are also known devices sliding door stop needing positive action to  the release of the door out of its open position.

Such a device is described in the document GB-2,135,724.

This device comprises an articulated hook on a charity car of the door. When the door is in your open position, the hook is coupled with a supportive stop of the guide rail

The hook is connected by a strap with a drive handle by which it can be coupled from the stop in order to bring the door to its closed position. When the hook is uncoupled from the stop, it does not create any force reaction between the shooter and the car.

However, this device is expensive because to the necessary connection between the handle and the hook.

The present invention aims to avoid the problem of blocking and improving a set such as the mentioned above in such a way that a couple of weak tilting when the door is taken out of position open

To this end, the invention aims at a set of the type mentioned above, characterized by the characterizing part of claim 1.

According to other embodiments, the invention It comprises one or more of the characteristics indicated in the subordinate claims 2 to 8.

In figure 1 a vehicle is represented car for example of the "minivan" type or of type utility designated by general reference 2.

Hereinafter, the expressions "previous", "posterior" and "laterally" will be used with respect to the usual orientation of the vehicle.

The vehicle 2 comprises a body 4 that delimits a lateral opening 6, which allows access to the interior of this vehicle 2, and in particular to the back of the cabin

A set 8 of sliding side door is mounted on the side side of the body 4. This set 8 it comprises a door 10, three sets of slides, respectively upper 12, central 14 and lower 16, and a stop device 18.

The door 10 is mobile in translation according to a horizontal and rectilinear sliding direction C, between a closed position that seals the lateral opening 6 (Figure 1) and an open position for releasing this lateral opening (not shown). It extends along a vertical door plane and has a height h measured in the plane of the door perpendicular to the direction C. The door is provided with a maneuvering handle 20.

Each of the slide assemblies 12, 14, 16 comprises a guide rail, respectively upper 22, central 24 and lower 26 which extend according to the direction of sliding C and an upper carriage 28, central 30 and lower 32 sliding mobile in lane 22, 24, 26.

Rails and trolleys upper 22, 28 and lower 26, 32 know themselves. Cars 28, 32 comprise a support wheel and, eventually, a side guide wheel.

The center lane 24 is symmetrical with respect to an M-M plane that extends perpendicular to the door plane and in the direction of sliding C.

The central carriage 30 is represented in the Figure 2 and is adapted to, on the one hand, support the weight of the gate 10 and, on the other hand, laterally guide gate 10 during its displacement.

The central carriage 30 comprises a base body 40 articulated to door 10 by means of an A-A axis that extends parallel to the plane of the door and perpendicular to the direction of sliding C. On the base body 40 is articulated a bearing wheel 42 around of a B-B axis that extends perpendicular to the A-A axis and C direction, as well as a wheel guided 44 around a C-C axis that extends parallel to the A-A axis.

Lane 24 is connected to body 4 vehicle.

The stop device 18 is adapted to keep the door 10 in its open position and comprises a stop 50 arranged at the rear end of the center rail 24 (see Figure 3) as well as a stop stud 52 integral with the base body 40 and extending along a D-D axis parallel to the B-B axis.

As illustrated in Figure 4, the stop 50 it comprises a crankcase 56, a block 58 of plastic material, especially of viscoelastic plastic material and in particular of EPDM as well as an insert 60. The stop 50 has a shape symmetric with respect to the M-M rail plane central 24.

The crankcase 56 comprises a fixing hole 62 in order to fix the stop to the body 4 and two fins of reception 64 of block 58 provided with retention legs 66.

Block 58 has a general form of C and it comprises two lateral branches 68, 70 connected by a soul 72. The two branches 68, 70 delimit a reception drain 74 of the pin 52 when door 10 is in its open position, as is represented in figure 2.

Each branch 68, 70 comprises, at its free end, an interlocking shoulder 76, 78 directed towards the plane M-M of the central lane 24 and towards each other. The interlocking projections 76, 78 extend along the path of the pin 52 during the movement of the door 10 between its open and closed positions.

On the other hand, some emptying of flexibility 80, 82 are practiced on the lateral branches 68, 70.

The insert 60 is made of a single piece in spring steel and has a C shape, complementary to that of the reception dump 74. The piece of insert 60 covers interlocking projections 76, 78 of such so that the pin 52 is applied on the insert 60 during its movement. Thus, block 58 wears little.

Insert 60 and block 58 as well as block 58 and receiving fins 54, are retained each other in the sliding direction C only by the cooperation for complementarity of forms.

The stop 50 according to the invention is assembled of as follows, as illustrated in figure 5.

First, the insert 60 is enter block 58 according to the sliding direction C.

Then the set consisting of a block 58 and insert 60 is inserted laterally, perpendicular to the direction C, between the receiving fins 54

Finally, the group consisting of the piece of insert 60, block 58 and crankcase 56 is inserted into the rear end of lane 24 according to direction C.

The assembly according to the invention functions from the next way.

In order to open the door, the passenger picks up the door 10 by the handle 20 and moves the door 10 from its closed position towards its open position. When door 10 is close to its open position, the pin 52 is applied on the interlocking projections 76, 78 by means of the insert 60, elastically deforms them out of their trajectory and interlocks at the reception dump 74.

In order to close door 10, the passenger push the door 10, by means of the handle 20, towards its position closed. The pin 52 then exceeds the projections 76, 78 which are hide deforming elastically and door 10 has freedom to move to its closed position.

Since the highlights 76, 78 are symmetrical and the handle 20 is arranged at the level of the stopping device in the sliding direction C, the forces applied on the shooter 20 create only a weak pair around the shaft D-D of the pin 52. Consequently, the risk of Door 10 barking is weak and only needs a small force to overcome the resistance force of the device detention 18.

In general, it is advantageous that the distance between a handle 20 and the stop 50 or the pin 52, measured according to the direction of the height h , is less than 10% of the height of the door, and preferably less than 5% of this height

The stop device according to the invention It has a reduced manufacturing cost since it comprises a viscoelastic symmetric block and since it is easy to assemble. By on the other hand, you don't need any means of positive liberation like detention devices provided with a hook.
