Definitions

• the present invention relates to a device for blocking the opening of a motor vehicle opening leaf and more particularly to a device comprising a first element integral with a structural element of the vehicle cooperating with a second element integral with the opening element and allowing the final immobilization of the opening after the first closing.
• Such devices have the disadvantage of requiring an additional operation on the assembly line and in most cases of requiring an adjustment of the position of the door in order to place opposite the fastening elements integral with the door and those integral with the vehicle structure.
• the object of the present invention is therefore to propose a device for locking an opening which is quick to implement while being active as soon as the door is closed for the first time and which accepts dispersions for positioning the opening with respect to its supervision and which is simple and economical to carry out.
• the invention relates to a device for locking a motor vehicle opening comprising a first element fixed to a structural element of the motor vehicle and a second element fixed to the opening, the first element cooperating with the second element to lock the opening in the closed position.
• the locking device of a motor vehicle opening is characterized in that the first element has a body which is inserted into an opening of the second element when the opening is closed, the second element comprising retaining means preventing movement of the body in the opposite direction.
• the retaining means consists of an elastic washer comprising a hole intended to receive the body, the hole having a diameter less than the outside diameter of the body and having radially grooves on its periphery to form flexible teeth.
• the washer is of frustoconical shape and is oriented so that the flexible teeth converge in the direction of penetration of the body through the hole when the door is closed.
• the second element consists of a housing comprising a housing in which the elastic washer is trapped, the housing being adapted so as to allow a radial movement of the washer, the latter having on its periphery a cylindrical flange, the ends of which come in close proximity to the walls of the housing in order to limit the axial movement of the washer.
• the first element consists of a rivet of the POP rivet type, the body of which is cylindrical.
• the housing comprises a cylindrical barrel extending by a shoulder, the cylindrical barrel of the housing coming to be inserted in a suitable opening of a wall of the box until the shoulder rests on the wall, the housing being immobilized against the wall using ears carried by the barrel cylindrical and enclosing the wall.
• the first and second elements are reversed, the first element being integral with the opening and the second element being integral with the structural element of the vehicle.
• FIG. 1 is a view of a body side of a motor vehicle having the location of a locking device of an opening according to the invention
• FIG. 2 is an exploded perspective view of a locking device of an opening according to the invention before its installation on the vehicle;
• FIG. 3 is an axial sectional view of the locking device of an opening of Figure 2 when it is operational on the vehicle.
• the device for locking the rear door 1 is advantageously arranged near the locking elements of the door 1 in an area in which a part of the box of the door 2 is opposite a structural element 4 of the vehicle.
• the device shown in Figures 2 and 3, comprises a housing 2 intended to be mounted on the rear door casing 1 and a rivet 3 fixed on the structural element 4 of the vehicle and intended to be inserted in the housing 2 to cooperate with the latter when the rear door 1 is closed.
• the rivet 3, as shown in FIG. 3, is fixed to the structural element 4 and has a body 7 formed by a cylindrical rod projecting perpendicularly to the structural element 4.
• the housing 2 produced for example by plastic molding, consists of a hollow cylindrical barrel 21 closed at one end by a wall 11, the other end of the cylindrical barrel 21 being extended by a shoulder 22 having a thread on its periphery, not shown in the figures, allowing the establishment of a flange 23 by screwing.
• the flange 23 has, in its center, an opening 25 intended to allow the body 7 of the rivet 3 to pass and comprises two holes 20 arranged on either side of the opening 25 and intended to allow the insertion of carried lugs by a tool to facilitate the screwing or unscrewing of the flange 23.
• the latter In order to allow an axial offset of the body 7 with respect to the opening 25, the latter has a diameter much greater than the diameter of the body 7 of the rivet 3.
• the housing 2 comprises a housing 5, delimited by the shoulder 22 and the flange 23, in which an elastic washer 6 is disposed and has a cavity 8 formed by the interior of the cylindrical barrel 21 allowing the body 7 of the rivet 3 to pass.
• the washer 6, made for example from a metallic material having good elasticity, has a frustoconical shape and has at its center a hole 24 provided with flexible teeth 28 intended to allow the body 7 of the rivet 3 to pass in one direction only.
• the elastic washer also has on its periphery a flange 26 extending parallel to the axis of symmetry of the washer 6 over a height slightly less than the height of the housing 5 so that the axial movement of the elastic washer 6 through the housing 5 is limited without however preventing its radial movement.
• the diameter of the elastic washer 6 is greater than the diameter of the cavity 8 so that the flange 26 is properly supported on the inner wall 29 of the shoulder 22 and less than the diameter of the housing 5 so as to allow a radial clearance of the elastic washer 6 through the housing 5.
• the housing 2 also includes, at the periphery of the cylindrical barrel 21, ears 27 disposed near the shoulder 22 and intended to hold the housing 2 when the latter is inserted in an opening made on a wall 9 of the box of the door 1.
• the immobilization of the housing 2 on the door 1 is carried out by inserting the cylindrical barrel 21 in the opening of the wall 9, this opening having notches adapted to allow the passage of the ears 27 in a given angular position of the housing 2, then by rotating the housing 2 so as to bring the ears 27 to a position for which the wall 9 of the box is clamped between the shoulder 22 and the ears 27.
• the body 7 of the rivet 3 secured to the structural element 4 is inserted into the opening 25 of the housing 2 until it comes into contact with the flexible teeth 28 of the washer 6.
• the teeth 28 tilt towards the interior of the cylindrical barrel 21 under the pressure of the body 7, the elastic washer 6 then automatically centering on the body 7 of the rivet 3 by the forces generated on the teeth 28.
• the body 7 is then inserted through the hole 24 to penetrate into the cavity 8 of the cylindrical barrel 21, the flexible teeth 28 being in abutment against the surface of the body 7.
• the door 1 is then locked in the closed position, the opening movement of the door 1 being blocked by the attachment of the teeth 28 on the body 7.
• the surface of the body 7 of the rivet 3 can be striated to increase the adhesion of the teeth 28 on the surface of the body
• the locking device thus produced has the advantage of being inaccessible from outside the vehicle and of being removable, without deterioration of the door 1, by accessing the housing 2 from the inside of the box of the door 1 and by releasing the housing 2 by rotation. Furthermore, such a device has the advantage of being easy to mount on the vehicle and of allowing a large dispersion of positioning of the housing secured to the box with respect to the rivet fixed to the structural element by means of self-centering. of the elastic washer on the rivet. Such a device also has the advantage of being able to be mounted on the door and on the vehicle structure before the door is mounted on the vehicle and to rehase the automatic locking of the door without any intervention being necessary after closing Door.
• the housing can be mounted integral with a structural element of the vehicle and the rivet can be mounted integral with the door.
