Description

The present invention relates to a door assembly

  slider, of the type comprising - a sliding door with respect to a wall in a sliding direction, between an open position away from an opening and a closed position of closing the opening, - the door extending along a door plane, and having a height measured perpendicular to the direction of sliding and following the door plane, - a handle for operating the door fixed to the door, - a door stop device in its open position, the stopping device having cooperating first and second stopping elements, the stopping elements being adapted to stop and release the door by elastic deformation of said first stopping element when the door is brought into its open position and out of its open position.

  It applies in particular to sliding doors of 20 motor vehicles.

  There are known devices for stopping sliding doors of motor vehicles. Such a device is described in 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 is guided a sliding carriage. This cart includes a roller.

  The stop device is provided with a ramp which is arranged on the rail. It defines a stop housing for the roller and is articulated between a position of passage of the roller and a locking position of the roller. The ramp is biased towards its blocking position by a viscoelastic block.

  A door equipped with such a device can be brought out of its open position by pushing towards its closed position. On this occasion, the roller crosses the ramp against the force exerted by the viscoelastic block.

  Generally, the stop devices of this kind are arranged at the upper or lower part of the door, while an operating handle is arranged on a central part of the door.

  As a result, when the door is pushed toward its closed position, the reaction force between the handle and the stopper creates a tilting torque of the door about an axis perpendicular to the plane of the door.

  This torque causes the carriage and leads to a risk of jamming the door. Also, the force required to bring the door out of its open position is important.

  Also known are sliding door stop devices requiring a positive action for the release of the door from its open position.

  Such a device is described in GB2.135.724.

  This device comprises a hook articulated on a carriage secured to the door. When the door is in its open position, the hook is engaged with an abutment integral with the guide rail.

  The hook is connected by a rod to an actuating handle by which it can be brought out of engagement with the stop so that the door can be brought into its closed position. When the hook is out of engagement with the stop, it does not create a reaction force between the handle and the carriage.

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

  The present invention aims to overcome the blocking problem and improve an assembly as mentioned above so that it creates a low tilting torque when the door is moved out of its open position.

  For this purpose the invention relates to an assembly of the aforementioned type, characterized in that the distance between the handle and said stop elements, measured perpendicularly to the direction of sliding and in the door plane, is less than 10. % of the door height, and preferably less than 5% of this height.

  In FIG. 1 is shown a motor vehicle for example of the mono-body type or the utility type designated by the general reference 2.

  In what follows, the expressions forward, back and laterally will be used in relation to the usual orientation of the vehicle.

  The vehicle 2 comprises a bodywork 4 defining a lateral opening 6, which allows access to the interior of the vehicle 2, and in particular to the rear part of the passenger compartment.

  A set 8 of sliding side door is mounted on the lateral side of the bodywork 4. This assembly 8 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 movable in translation in a horizontal and rectilinear sliding direction C, between a closed position closing the lateral opening 6 (FIG. 1) and an open position for releasing this lateral opening (not shown). It extends along a vertical door plan and has a height h measured in the door plane perpendicular to the direction C. The door is provided with an operating handle 20.

  The slide assemblies 12, 14, 16 each comprise an upper guide rail 22, central 24 and lower 26 extending in the direction of sliding C and an upper carriage 28, central 30 and lower 32 movable in sliding in the rail 22, 24, 26.

  The upper rails and carriages 22, 28 and lower 26, 32 are known per se. The carriages 28, 32 comprise a support roller and possibly a lateral guide roller.

  The central rail 24 is symmetrical with respect to a plane MM extending perpendicular to the door plane and in the sliding direction C. The central carriage 30 is shown in FIG. 2 and is adapted to, on the one hand, support the weight of the door 10 and, secondly, laterally guide the door 10 during its movement.

  The central carriage 30 comprises a base body 40 hinged to the door 10 by an axis AA extending parallel to the door plane and perpendicular to the direction of sliding C. On the base body 40 is articulated a carrier roller 42 around an axis BB extending perpendicular to the axis AA and to the direction C as well as a guide roller 44 about an axis CC extending parallel to the axis AA.

  The rail 24 is connected to the bodywork 4 of the vehicle.

  The stop device 18 is adapted to hold the door 10 in its open position and comprises an abutment 50 disposed at the rear end of the central rail 24 (see FIG. 3) and a stop lug 52 secured to the body. base 40 and extending along an axis DD parallel to the axis BB.

  As illustrated in FIG. 4, the abutment 50 comprises a casing 56, a block 58 made of plastic material, in particular a viscoelastic plastic material and in particular EPDM, and an insert 60. The abutment 50 has a symmetrical shape with respect to the MM plane of the central rail 24.

  The housing 56 comprises a fixing orifice 62 for fixing the stop on the bodywork 4 and two receiving wings 64 of the block 58 provided with retaining tabs 66.

  The block 58 has a general shape of C and comprises two lateral branches 68, 70 connected by a core 72. The two branches 68, 70 delimit a receiving recess 74 of the lug 52 when the door 10 is in its open position. as shown in Figure 2.

  Each branch 68, 70 comprises, at its free end 10, a detent projection 76, 78 directed towards the plane M-M of the central rail 24 and towards one another. The snap protrusions 76, 78 extend in the path of the lug 52 as the door 10 moves between its open and closed positions.

  In addition, softening recesses 80, 82 are provided in the side branches 68, 70.

  The insert 60 is made of a single piece of spring steel and is C-shaped, complementary to that of the receiving recess 74. The insert 60 covers the snap-on projections 76, 78 in such a way that that the lug 52 is applied to the insert 60 during its displacement. Thus, the block 58 is little used.

  The insert 60 and the block 58 as well as the block 58 and the receiving flanges 64 are retained relative to each other in the sliding direction C only by complementary shape cooperation.

  The abutment 50 according to the invention is assembled in the following manner, as shown in FIG. 5.

  First, the insert 60 is plugged into the block 58 in the direction of sliding C. Then the assembly consisting of a block 58 and the insert 60 is plugged laterally, perpendicularly to the direction C, between receiving wings 64.

  Finally, the group consisting of the insert 60, the block 58 and the housing 56 is plugged into the rear end of the rail 24 in the direction C. The assembly according to the invention operates as follows.

  In order to open the door, the passenger grasps the door at the handle 20 and moves the door 10 from its closed position to its open position. When the door 10 approaches its open position, the lug 52 is applied to the latching projections 76, 78 through the insert 60, deforms these resiliently out of its path and snaps into place. the receiving recess 74.

  In order to close the door 10, the passenger pushes the door 10, via the handle 20, to its closed position. The lug 52 then crosses the projections 76, 78 which fade by elastically deforming and the door is free to move to its closed position.

  Since the protrusions 76, 78 are symmetrical and the handle 20 is arranged at the stop device in the direction of sliding C, the forces applied on the handle 20 create only a small torque around the handle. DD axis of the pin 52. Consequently, the risk of jamming of the door 10 is low and it requires only a small force to overcome the resistance force of the stop device 18.

  In general, it is advantageous that the distance between a handle 20 and the abutment 50 or the lug 52, measured in the direction of the height h, is less than 10% of the height of the door, and preferably less than 10% of the height of the door. at 5% at this height.

  The stop device according to the invention has a low manufacturing cost since it comprises a symmetrical viscoelastic block and since it is easy to mount. Moreover, it does not require any positive release means such as stop devices equipped with a hook.
