Definitions

  • the present invention relates to a device for controlling the opening of a lock and in particular of a motor vehicle door lock comprising a locking mechanism intended to lock the bolt (4) in its open and closed positions and an electromechanical device for controlling this mechanism for the opening of the lock, which are connected by a sliding coupling member (24) moved by the electromechanical device and connected to an articulated latch (16) of the locking mechanism, the control device comprising a screw (32) rotated by an electric motor (30) and engaged with a toothed wheel (34) which moves a cleat (42) abutting against a lug (26) of the sliding coupling.
  • a device for controlling the opening of a lock and in particular of a motor vehicle door lock comprising a locking mechanism intended to lock the bolt (4) in its open and closed positions and an electromechanical device for controlling this mechanism for the opening of the lock, which are connected by a sliding coupling member (24) moved by the electromechanical device and connected to an articulated latch (16) of the locking mechanism, the control device comprising a screw (32) rotated by an electric
  • the electromagnetic device generally comprises an electric motor which drives either (EP-A-106 725) a reduction gear causing the displacement of a rack and pinion system integral with the sliding member or (according to a known technique of the plaintiff who, however, does not cite any document) a toothed wheel moving a driving cleat in abutment against a projection of the sliding coupling member, as well as an electrical device which stops the motor and consequently interrupts the drive when the sliding member has reached the desired open or closed position. 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.
  • FR-A-2,474,573 discloses an electrical actuation device in which the motor is connected to a sliding member by means of a mechanical drive link so that the stopping of the The drive is not subject to stopping the engine.
  • this connection is a unidirectional drive system which automatically reverses when the sliding member is immobilized by an end-of-travel stop, which makes it unsuitable for use in an electromechanical device for controlling the opening alone.
  • 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.
  • This object is achieved by providing in a device for controlling the opening of a lock according to the preamble of claim 1 the characteristics mentioned in the characterizing part of this claim 1.
  • 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 door lock for a motor vehicle shown in FIGS. 1 and 2 comprises a housing 1 provided with an opening 2 for introducing a strike G and enclosing a pivoting bolt 4 which comprises a notch 6 for housing the strike between two nozzles 8 and 10 respectively, this bolt pivoting around 'a hinge pin 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 member for coupling and transmitting motion ment between the locking mechanism and a device for controlling the opening of this mechanism.
  • the slider 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 the outside. of 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 fixed washer 46 Opposite from each of the holes 48, the fixed washer 46 has a recess 52 curved 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 toothed wheel 34.
  • the washer 46 having rotated, the balls have been pushed back by the ramps 54 until they protrude significantly from the opposite face of the fixed washer 44, the disc 41 is clamped 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 pressed 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 drives 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 the latter to descend along the ramp 54 to penetrate the part of greatest depth of the recess, and thus to release 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 lock 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 the direction 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 in the notch 45 until the hook 18 of the latch 16 abuts on the spout 10 of the bolt 4 and stops the movement (Fig. 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 up to the end of the notch 45 and even causes the washer 46 to rotate to bring it in the clutch position shown in Figs. 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 30 as soon as the latter is supplied, for example by means of external contactors of known type which need not be described or represented.
  • 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 safely operate 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 slide reaches the useful end of travel.
  • Returning to the cleat drive position is also automatic when the door is closed.
