Definitions

  • the present invention relates to a lock, in particular for the door of a motor vehicle, of the type comprising on the one hand a housing for the lock mechanism and on the other hand a keeper movable relative to this housing, the lock mechanism being provided with a part of a bolt oscillating around an axis which is perpendicular to the direction of movement of the keeper with which this bolt cooperates by a fork-shaped portion, and secondly of a movable lever for maneuvering the lock which is intended to authorize the rotation of the bolt in the direction of release of the striker by means of a locking member interposed between the bolt and the operating lever, the locking member being mounted movable in the one of the two parts formed by the bolt and the operating lever between a projecting position to secure the parts and a retracted position to allow the free movement of rotation of the bolt relative to the lever, the second of the two parts comprising for the securing at least one notch into which the blocking member is intended to penetrate, the two parts being mounted so as to be able to move apart from
  • the present invention aims to improve the lock defined above mainly for the following reasons.
  • the door locks of current motor vehicles of the type defined above ensure the closing of the door under the action of a force due to a manual push combined with the inertial forces resulting from the slamming of the door.
  • Manual action combined with inertial forces gives the seals, generally fixed to the body, a certain compression which ensures the airtightness of the vehicle
  • the weight gain currently sought by all manufacturers to reduce the vehicle's energy consumption results in a reduction in the mass of the doors, which reduces the inertia forces due to the slamming of the door and results in less good compression. of the gasket thereof, which further accentuates the defects mentioned above.
  • the object of the invention is precisely to remedy these defects and it therefore relates to a lock defined above which is characterized in that the bolt is coupled to an assisted drive mechanism around its axis of oscillation in the direction of closing the lock.
  • the closing of the door is no longer dependent on a manual action or the inertia of the door itself but on a motive force of a predetermined value generated in the lock and triggered in the final phase of closing the door.
  • the lock shown in the drawings comprises a housing 1 in which a blind passage 3 is provided, provided with a flared entry 4 in which is intended to penetrate a keeper 5, it being understood that this lock is designed to be mounted on the edge of a door of a motor vehicle, the keeper being fixed on the upright of the bodywork associated with the door.
  • the design of the lock in no way prevents a reversal of this layout, with minor modifications.
  • the keeper 5 is therefore movable in translation relative to the passage 3.
  • the lock comprises a lock mechanism 6 which firstly comprises a bolt 7B mounted oscillating around an axis 8 which is fixed in the housing parallel to the bottom of the latter. With this bolt cooperates an operating lever 9 which is mounted oscillating around a pin 10 also fixed on the bottom of the housing 1.
  • a locking member 12 which has the general shape of a roller.
  • This roller is housed in a notch 20 which is formed in the periphery of the bolt 7B, the latter also comprising a heel 23 forming a stop intended to come into abutment against the rear edge of the operating lever 9 when the bolt is in the corresponding position when the lock is opened.
  • the bolt 7B comprises, roughly diametrically opposite the notch 20, a notch 24 which is intended to receive the keeper 5 and to retain it when the bolt is in the position corresponding to the closing of the lock.
  • a spring 25 which biases this lever in its position of release or release of the roller 12 and this spring is supported on the one hand on a stop 26 integral with the housing 1 and secondly in a notch 27 formed in the rear edge of the operating lever 9.
  • notches 30, 31 and 31a are used for receiving the locking member 12, the notch 30 corresponding to the complete closure of the lock, the notch 31 to a so-called “first notch” closure and a third notch which corresponds to a so-called “second notch” position.
  • the first two positions are intended to secure the vehicle door when the user has not closed it properly. This poor closing is generally noticeable, when the vehicle is moving, by vibrations of the door, because it is not closed until the seals are compressed, the user being thus encouraged to carry out a complete closing. .
  • the first and second notches are in fact provided to meet international standards governing the construction of door locks for motor vehicles, although these notches are strictly speaking not necessary in the lock according to the invention since as as will be seen below, as soon as the mechanism 6 of this lock is in one or other of the positions corresponding to the first or the second notch, assisted locking of the lock is carried out.
  • the lock also comprises an electric motor 33 coupled to an endless screw 34 which meshes with the toothing of a toothed wheel 35 rotatably mounted on a spindle 36 fixed in the housing.
  • This toothed wheel comprises, at the periphery of one of its faces, a cavity forming a cam surface 39 cooperating with a pusher 41 of a switch 42 fixedly mounted in the housing.
  • a cup 60 On the spindle 36 of the toothed wheel 35 is rotatably mounted a cup 60 whose bottom is turned towards the toothed wheel and whose peripheral flange 61 constitutes a cam with which a roller 62 forms a cam follower which is mounted to rotate on a pivot 63 secured to the operating lever 9.
  • the rim 61 has a deformation 64 over a small part of its periphery, this deformation corresponding to the lower part of the cam path formed by this rim.
  • a puncture 65 is formed in the bottom of the cup 60 forming a tongue 66 bent at 90 ° in the direction of the wheel 35 and thus penetrating into a cavity 67 formed in the wheel 35.
  • This cavity 67 is in an arc centered on the axis of the spindle 35 and extends over a predetermined angle.
  • the spring 69 urges this cup in the direction of arrow F6 (fig. 1).
  • the rim 61 of the cup 60 also includes a cleat 70 which extends axially from its peripheral edge and which cooperates with a lever 71 for emergency release which is mounted oscillating on a pin 72 fixed between the bottom 1 of the housing and a support plate 73 in which are also fixed the corresponding ends of the spindle 8 and of the axis 10.
  • a yoke 74 is provided at the end of the lever 71 opposite to that intended to come into contact with the cleat 70 in which is articulated an operating rod 75 at the end of which is provided an emergency actuation button 76 which is preferably located in a housing formed in the interior wall of the door so as to be easily accessible to the passengers of the vehicle.
  • the lever 71 is attached by the same end to a return spring 77 also attached to the housing 1 and urging this end of the lever against a stop 78 secured to the wall of the housing 1.
  • Pin 36 is fixed in a support plate 79 integral with the housing and also serving to consolidate another pin 80 whose axis is parallel to those of pins 8, 10, 36 and 72, and around which is mounted oscillating a crew 81 assisted blocking of the lock.
  • This equipment comprises a toothed sector 82, the toothing 83 of which meshes with a portion of toothing 84 provided at the periphery of the bolt 7B.
  • the crew 81 which has roughly the shape of a yoke with asymmetrical branches, also comprises a connecting portion 85 which extends parallel to the axis of the boche 80 and which is extended, at right angles, by a operating arm 86 extending parallel to the bottom of the housing 1 but on the opposite side with respect to the support plate 79.
  • the equipment 81 is thus articulated doubly on the spindle 80.
  • a thrust tab 87 which again extends at a right angle to this arm in the direction of the wheel 35 and which cooperates with a roller 88 rotatably mounted around a pivot 89 secured to the wheel 35 and the axis of rotation of which extends parallel to the axis of the spindle 36.
  • a helical spring 90 is wound around the spindle 80 to urge the crew 81 in a counterclockwise direction as shown in fig. 1, that is to say in a direction tending to place the bolt 7B in its open position.
  • the bolt 7B is provided at its periphery, in a position approximately diametrically opposite with respect to the toothing 84, of an insulating track 91 forming a cam track cooperating with a feeler 92 secured to the movable contact 93 of a switch 94 provided of two fixed contacts 95 and 96, the movable contact 93 being in abutment against the fixed contact 95 when the probe 92 is on the upper range 91 of the cam path (this position will be referred to below as position "0" of the switch 94).
  • roller 12 is held in place by a yoke 100 which overlaps the area of the bolt 7B in which the notch 20 is located and this yoke is held on the latch by two rods 101 and 102 which extend between the wings of this yoke and which penetrate into small notches 103 and 104 formed in the bolt.
  • Figs. 7A to 7D represent, in four configurations, the electrical circuit which can be used with the lock according to the invention.
  • the diagram shown shows the switches 42 and 94 connected in series with the motor 33 on a power source which may be the vehicle battery.
  • a power source which may be the vehicle battery.
  • actuation button 105 which is a two-position switch operable by the user of the vehicle.
  • this switch must either be double, or be provided with control means arranged in such a way that this switch can be actuated both from outside and from inside the vehicle.
  • any control means can be provided such as a magnetic card, a key switch, or any other similar means.
  • a simple control button can be provided.
  • Fig. 6A shows the situation when the lock is open. Under these conditions, the keeper 5 is released from the bolt 7B and to initiate the closure, the keeper 5 must approach the lock in the direction of the arrow F7, this movement of course being relative.
  • the roller 12 is not in any of the notches of the operating lever 9 while the lever 86 is in its lower extreme position defined by its rotation connection with the bolt 7B, which is in abutment by its heel 23 against the lever 9 As for the wheel 35, it is placed in a position in which the roller 88 is almost in contact with the lever 86 which is biased in this position by the spring 90. Furthermore, the switch 94 is in the position "0" because the feeler 92 is on the lower range of the cam track 91.
  • the switch 99 is in the "0" position because the feeler 41 has left the cavity of the wheel 35. If the door is now closed, the keeper 5 pushes the bolt 7B into the position in which the roller 12 can penetrate into the first notch 31a of the operating lever 9. Under these conditions, the switch 94 changes position since its feeler goes up on the upper range of the path cam 91, which places the commu in its position "1". Under these conditions, the electrical circuit of the motor 33 is closed and this motor is therefore supplied. This results in the rotation of the wheel 35 which by its roller 88 begins to push the lever 86 which rocks around the spindle 80 by driving the toothed sector 82.
  • the button 105 is actuated, which again supplies the motor 33 via the contact 97, the movable contact of the button 105 and the movable contact 93, this circuit being kept closed as soon as the movable contact 97 switches again due to the fact that the probe 41 leaves the cavity of the wheel 35.
  • the opening of the lock is carried out when the roller 62 enters the deformation 64 of the rim of the cup 60 and the keeper 5 can then free yourself from the bolt 78.
  • the lock can nevertheless be opened by the emergency control formed by the lever 71 which is actuated in this case by the pull tab 75 and the button 76.
  • the lever oscillates around the axis 72 coming into contact with the cleat 70 of the flange 60. This results in a slight rotation of this cup relative to the wheel 35 around the spindle 36, movement which is allowed due to the fact that the cavity 67 provided in the wheel 35 has an angular extent a just sufficient for the roller 62 can penetrate the deformation 64 provided in the rim of the cup 60. Consequently, as soon as the lever 71 is actuated, this cup performs a movement relative low amplitude relative to the wheel 35, the lever 9 can tilt, the roller 12 is released and the keeper can escape from the bolt 7B.
  • the lock can operate in accordance with the sequences described above.
