Definitions

  • the present invention relates to locks for doors of a motor vehicle and in particular locks comprising a locking mechanism intended to lock the bolt in its open and closed positions and an electromechanical device for controlling this mechanism for the opening of the lock qüi - are connected by a sliding coupling member moved by the electromechanical device and provided with means for driving an articulated lock of the locking mechanism.
  • the electromechanical device generally comprises a toothed wheel driven by an electric motor and moving a driving cleat which cooperates with a projection of the sliding coupling member, as well as an electric device which stops the motor. and consequently interrupts the drive of the toothed wheel when the sliding member has reached the desired position of opening or closing. It is therefore necessary to provide inside the lock a certain number of electrical contactors as well as corresponding electrical connections, which makes the production of the lock complex, but above all requires providing effective protection against humidity and in particular rainwater.
  • the present invention aims to remedy these drawbacks by providing an efficient and safe control device which does not use an internal electrical contactor in the lock.
  • the subject of this invention is in fact a device for controlling the opening of a lock of the above type, in which a screw driven in rotation by an electric motor displaces a driving cleat with a projection of a coupling slide which comprises means creating a link :: drive sound between the cleat and the wheel during a determined angular travel of the latter which corresponds to the displacement of the slide between its closed and open positions of the lock, this connection being automatically disengaged by the arrival of the slide in the open position.
  • the locking mechanism immobilizing the slide in each of its open and closed positions and the drive link between the cleat and the toothed wheel being automatically interrupted when the slide arrives in the open position, it does not It is not essential to stop the engine immediately.
  • the toothed wheel can indeed continue to rotate for an indefinite time without changing the position of the lock.
  • the means for creating a drive connection between the cleat and the toothed wheel comprise ramps which cooperate with balls to push back the cleat in engagement with the wheel.
  • the balls and the ramps are mounted respectively on two rings coaxial with the toothed wheel, one of which is fixed, while the other is moved by the slide arriving at the end of the opening or closing.
  • the lock for the door of a motor vehicle shown in Fig. 1 and 2 comprises a box 1 provided with an opening 2 for introducing a keeper G and enclosing a pivoting bolt 4 which comprises a notch 6 for housing the keeper between two nozzles 8 and 10 respectively, this bolt pivoting about a hinge axis 12 and being returned to its open position shown in FIG. 1 by a spring 14 mounted on the axis 12.
  • the housing 1 also contains a locking mechanism intended in particular to block the keeper in the opening.
  • This mechanism comprises a latch 16 pivotally mounted on an axis 17 and forming a hook 18 for cooperation with the beaks of the bolt 4.
  • the latch 16 At its end opposite to the axis 17, the latch 16 comprises a latching finger 20 which comes fit into a cavity 22 formed at the lower end of a slide 24 provided with a projection or lug 26 and thus constituting a coupling and transmission member movement between the locking mechanism and a device for controlling the opening of this mechanism.
  • the slide is pushed back towards the opening 2, that is to say towards its locking position by a spring 28 mounted between it and a fixed cleat 30 of the housing.
  • the movement of the slide 24 against the action of the spring 28, that is to say towards the open position of the door, is controlled from an electric motor 30 (FIG. 2) which is supplied from outside the housing. and causes the rotation of a screw 32.
  • This screw 32 is engaged with a toothed wheel 34 which is free to rotate on an axis 35 fixed in the housing 1.
  • the wheel 34 is hollow and its bottom 36 which is crossed by the axis 35, has on its internal surface radial grooves 38 (Fig.3).
  • Radial grooves 40 similar to the grooves 38 are formed on a disc 41 which is also mounted on the axis 35 but is both free to rotate and capable of moving axially relative to this axis.
  • the disc 41 is mounted inside the toothed wheel 34 and carries on its face opposite to the toothing 40 a tab 42 projecting outside this wheel.
  • the cleat 42 has an axial length such that it successively passes through a notch 43 formed at the periphery of a fixed washer 44 secured to the axis 35 then a notch 45 formed at the periphery of a movable washer 46 mounted to rotate freely on axis 35.
  • the fixed washer 44 is pierced with a number of holes 48 which pass through it and each serve as a housing for a ball 50 which is thus capable of projecting from one or the other of the faces of the washer 44.
  • the ron fixed delle 46 Opposite from each of the holes 48, the ron fixed delle 46 has a curved recess 52 coaxially with the washer 46, one of the side walls of which forms an inclined ramp 54 so that the depth of the recess decreases progressively in this direction (FIG. 4).
  • the balls are aligned with the deep part of the corresponding recess 52 (Fig.5) or with the upper part of the ramp 54 as shown in Fig. 6.
  • the balls 50 are thus inside the recesses 52, they only make a very slight projection on the opposite face of the fixed washer 44 so that the disc 41 is free between this washer and the bottom 36 of the wheel toothed 34.
  • the washer 46 having rotated, the balls have been pushed back by the ramps 54 until they protrude significantly on the opposite face of the fixed washer 44, the disc 41 is pressed by these balls against the bottom 36 of the toothed wheel 34. Consequently, the grooves 40 of the disc 41 come into engagement with the grooves 38 of the bottom 36 of the toothed wheel and secure these two rotating members.
  • the cleat 42 is consequently driven by the toothed wheel 34.
  • the notches 45 of the movable washer 46 and 43 of the fixed washer 44 are also crossed by the projection or the lug 26 of the slide 24 so that the movement of the cleat 42 in a clockwise direction considering the Figs .7,8 and 9 causes that of the slide 24.
  • the slide 24 In the closed position of the lock, that is to say when the keeper G is blocked inside the notch 6 of the bolt 4 and the spout 8 of this bolt is immobilized by the hook 18 of the latch 16, the slide 24 is in the depressed position, that is to say in its position closest to the opening of the housing 1.
  • the lug 26 is in contact with the cleat 42 which is itself supported on the edge of the notch 45 of the washer 46 as shown in Fig. 7. At this moment, the washer 46 is in the same position as in FIG. 6.
  • the ramps 54 therefore push the balls 50_ outwards, that is to say in the direction of the disc 41.
  • the grooves 40 and 38 are engaged and the cleat 42 is integral with the toothed wheel.
  • the rotation of the screw 32 causes that of the toothed wheel 34 and causes the displacement of the cleat 42 in the notch 45.
  • the cleat 42 entrains the lug 26 until it contacts with the opposite end of the notch 45 then the toothed wheel 34 continuing to rotate, pushes the washer 46 which in turn turns.
  • each of the recesses 52 moves under the ball 50 and allows it to descend along the ramp 54 to penetrate into the portion of greatest depth of the recess, and thus free the disc 41 which is no longer clamped against the toothed wheel 34.
  • the slope of the grooves 38 and 40 is such that the disc 41 deviates from itself from the bottom 36 of the toothed wheel 34.
  • This toothed wheel 34 can continue to rotate under the action of the screw 32 and the motor 30, but the disc 41 and the cleat 42 are no longer driven.
  • the slide 24 has been moved away from the opening 2 by driving the finger 20 so that the latch 16 has pivoted and released the bolt 4.
  • the lock is unlocked and the keeper G is free.
  • the slide 24 and consequently the lug 26 are pushed back by the spring 28 in direct tion of the opening 2 and tend to pivot the latch 16 in the direction of the bolt 4.
  • the lug 26 therefore exerts a force on the cleat 42 which, like the disc 41 is free to rotate, the grooves 38 and 40 being disengaged .
  • the lug 26 therefore pushes the cleat 42 back into the notch 45 until the hook 18 of the latch 16 abuts the spout 10 of the bolt 4 and stops the movement (FIGS. 1 and 9).
  • the mechanism is then immobilized in the open position of the lock, the bolt 4 being ready to receive the keeper G.
  • the keeper G enters the opening 2 then in the notch 6 of the bolt 4 and pushes the latter until it is released from the hook 18 of the latch 16.
  • the slide 24 moves by driving the lug 26.
  • the latter pushes the cleat 42 to the end of the notch 45 and even causes the rotation of the washer 46 to bring it in the clutch position shown in Fig.6 and 7.
  • the locking mechanism blocks the keeper G in the bolt 4 while the cleat 42 of the control device is made integral with the toothed wheel 34 and is ready to be driven by the motor 3 0 as soon as it will be supplied, for example via external contactors known type that does not need to be described or shown.
  • the device for controlling the opening which has just been described enables the desired displacement of the coupling slide of the locking mechanism to be obtained safely and effectively without requiring the use of contactors or other electrical components. inside the lock.
  • This movement is in fact independent of the duration of supply of the motor 30 which can without danger actuate and even drive the toothed wheel 34 for a period significantly greater than that necessary for opening, since the cleat 42 is automatically made independent of this wheel, when the slider reaches the useful end of travel.
  • the return to the cleat drive position is also automatic when the door is closed.
