Definitions

  • the invention relates to a lock for a door leaf of a motor vehicle, in particular a door.
  • a lock for a door of a motor vehicle provided, on the side of the door, with a pivoting bolt which, when the door is closed, surrounds a keeper and is locked by means of '' a pivoting ratchet or catch.
  • the stop pawl can pivot from a locking position to an unlocking position by means of a rotating eccentric which is connected to an electric motor by means of a gear.
  • the main drawback of this known lock is that the control of the pawl via the gear and the eccentric takes up a relatively large amount of space.
  • the stop pawl remains in the unlocked position until the eccentric turns by an angle greater than 180 °. When the eccentric jams or during a breakdown of current, it is very difficult to re-pivot the stop pawl to its locked position.
  • the object of the invention is to provide a lock of the type mentioned above according to which the stop pawl returns as quickly as possible to its blocking position after having reached its unlocking position.
  • the lock must be able to be mounted taking up as little space as possible.
  • the lock according to the invention comprises two crank pins offset by 180 ° relative to each other, the two crank pins are projecting from the crank disc so that it suffices to a maximum rotation of 180 ° of this disc to pull and unlock the stop pawl.
  • a switch can be provided which can be actuated by the crankpins of the crankpin disc and which stops the electric motor each time the stop pawl reaches its unlocked position.
  • the first connecting lever is in the form of a fork.
  • a damping piece can be arranged on the lock, the stop pawl having a stop, so that said stop pawl is braked by the damping piece during the pivoting movement caused by the pawl spring, the unlocked position to the locked position.
  • the gear can be a disc gear without brake; the crankpin disc can be a wheel.
  • the invention is based on the idea of using, instead of an eccentric, a crank disc with at least one crank pin arranged on this disc, which cooperates, directly or by means of a linkage lever with a coach. of the stop pawl.
  • the position of crankpin on the crankpin disc and the length of the driver or linkage lever in the crankpin area allows the crankpin to drive the linker or linkage lever only until the unlock position be reached.
  • the driver or link lever has pivoted so far because of the crankpin that it passes over the driver or link lever and thus unlocks the stop pawl.
  • This stop pawl is then returned by a suitable spring to its blocking position, so that, when the door is closed, the stop pawl can block the latch in the known manner.
  • a worm gear as a gear
  • the lug disc being constructed like a toothed wheel and thus corresponding to a part of the gear.
  • the motor While the start of the electric motor is triggered by a switch arranged on the door handle, the motor is stopped, preferably, by means of a miniature switch, which can be actuated by the crankpin disc, as soon as the stop pawl is in the unlocked position (and therefore as soon as the crankpin concerned actuating the driver or the linkage lever has passed over these parts).
  • the crank disc is braked (electrically) by the engine.
  • FIG. 1 shows a door lock for an automobile designated by 1, the housing 2 of which has a recess 3 which, when the door of the automobile is closed, houses a keeper 4, which is fixed to the body of the automobile.
  • the keeper 4 enters the notch 5 of a bolt 6 which is arranged so as to be able to rotate about an axis 7 parallel to the keeper 4.
  • the bolt is blocked by a stop pawl 8 ( Figure 3).
  • the housing 2 further comprises an electric motor 9 which acts by means of a worm gear 10 on a disc 11 with crankpins, which is a tangent wheel and which is housed so as to be able to rotate around a axis 12.
  • the crank pin disc 11 comprises two crank pins 13, 14 placed opposite one another, which, during the rotation of the disc 11, penetrate each time into a hollow of a first lever of link 15, constructed in the form of a fork, and which make the latter pivot about an axis 16 (FIG. 2).
  • a second link lever 17 is also arranged on the axis 16, which link lever 17 is integral in rotation with the first link lever 15 and is located against a driver 18 secured to the stop pawl 8.
  • the electric motor 9 is connected by means of appropriate conductors to a control device (not shown), which in turn is connected to switches also not drawn, placed on the door handles, as well as to a miniature switch arranged on the crankpin disc.
  • the electric motor 9 When, to open a car door, the handle of said door is actuated and therefore also the associated miniature switch, the electric motor 9 is activated by means of the control device. This electric motor drives via the worm gear 10 the disc 11.
  • One of the two crankpins 13, 14 enters the hollow 20 of the fork (FIG. 1) of the first link lever 15, which pivots around of the axis 16.
  • the second link lever 17 With the first link lever 15, the second link lever 17 also pivots and it presses against the driver 18 of the stop pawl 8 and makes it pivot in the direction of arrow 22 ( figure 3) going against the pressure of a spring 21 (figure 2). This operation continues until the bolt 6 is no longer blocked by the stop pawl 8 (unlocking position). Once the blocking by the pawl 8 is removed, the door of the automobile opens by the pressure of the exterior seals of the door and the keeper 4 is withdrawn out of the hollow 3.
  • crankpin 13, 14 concerned passes over the end 23, located on the crankpin side, of the first connecting lever 15.
  • the spring 21 brings the stop pawl 8 back into the blocking position by pressing on it, an excessively brutal shock being avoided by means of a damping piece 24.
  • the miniature switch (not shown) located on the disc 11 is actuated by the second crankpin 14 , 13 respectively, the electric motor 9 is stopped by means of the control device and the disc 11 is electrically braked.
  • the gear need not be a worm gear.
  • Those of the ends of the ratchet driver or the linkage levers which are close to the crankpin disc need not be constructed in the form of forks.
  • the crankpin disc may also include a single crankpin or, on the contrary, more than two crankpins.
