Definitions

  • the present invention relates to a lock with Doppelhubauslect, in particular for the front flap of a motor vehicle, comprising a catch for receiving a striker and a catch hook for securing the released of the catch latch in a trapped position.
  • Front door locks for motor vehicles are basically known. Conventionally, a front door lock is pre-unlocked by a single actuation of a first actuating element in the motor vehicle interior, whereby the striker is brought into a trapped position in which he is still caught and secured by the fishing hook. Subsequently, the striker can be freed from the catch hook by the operation of a second actuating element on the front flap and the front flap can be swiveled open.
  • the invention has for its object to provide a lock with Doppelhubauslect, which has a simpler design and at the same time a higher reliability.
  • the object is achieved by a lock with the features of claim 1 and in particular by the fact that the catch hook assumes the function of a pawl for the catch.
  • the invention is based on the general idea to use the fishing hooks not only to secure the released from the catch latch in the trapped position, ie in Vorentriegelungs- or Vorverrieglungsschreib, but the fishing hook ke with another function, namely the ke a ke for the catch, to provide.
  • the fishing hook can be dispensed with a separate pawl, which reduces the number of required components and the lock can be produced with a lower economic cost.
  • the double function of the catch hook allows the striker when closing the front cover automatically, ie only by the weight of striker and front door, gets into its trapped position.
  • the catch hook on a locking element which locks the catch in a locking position.
  • This blocking element can be, for example, a protruding rivet, pin or pin, wherein in principle also any other suitable projections come into question.
  • the locking element in particular with rotation of the fishing hook, can be overcome by the rotary latch when the rotary latch is rotated by the striker in its locking position.
  • the rotary catch acted upon by the striker can push the catch hook sideways during the closing process and thereby move past the blocking element.
  • the catch hook is preferably connected to a pulling means, by which the catch hook can be rotated from a catching position in which it can hold the striker into a release position, in which the striker can pass the catch hook .
  • the traction means may, for example, be a bow tie.
  • the traction means acts on a lever which is rotatably mounted on the catch hook.
  • the catch hook on a blocking element which blocks the catch in an intermediate position between the locking position and an open position when the traction means starting from a locked state of the lock a first time tensioned and the catch hook is rotated in its release position (first stroke).
  • the blocking element prevents the catch from rotating to its open position and releases the striker, while the catch hook has left its catch position and could not thereby catch the striker.
  • the catch hook preferably pivots back into its catch position and the catch rotates further into its open position, so that the striker is released from the catch and caught by the catch, which again ensures that the front flap can not open unintentionally ,
  • the lever located in the storage position engages in a subsequent second relaxation of the traction means with the released from the catch latch in engagement to hold the striker in a storage position and the fishing hook in the release position. From this state, the front flap can either be opened by folding up or locked by pressing down again.
  • the catch hook and the rotary latch are mounted independently of each other and rotatable about mutually parallel axes of rotation.
  • the rotary latch against the restoring force of a first spring from an open position into a locking position is rotated.
  • the first spring should be dimensioned so strong that it is able to lift the front flap.
  • the fishing hook is against the restoring force of a second spring from its catching position into its release position rotated.
  • the lever carried by the catch hook can be rotated counter to the restoring force of a third spring in the storage position.
  • the restoring force of the third spring is preferably lower than that of the second spring.

  • the rotary latch 10 has a mouth 16 for receiving a mounted on a front flap, not shown striker 18.

  • the front flap lock further comprises a catch hook 28, which is also rotatably mounted on the housing 12, namely about a second axis of rotation 29 spaced parallel to the first axis of rotation 14.
  • the fishing hook 28 is against the restoring force of a second spring 30 from a catch position ( Fig. 1) in a release position (Fig. 2) rotatable in the figures so counterclockwise.
  • the catch hook 28 has a substantially U-shaped configuration, wherein a first leg 32 of the catch hook 28 terminates in the catching position of the catch hook 28 approximately in the area of the mouth 16 of the rotary latch 10 in its open position in a forked seat 33, while a second leg 34 of the fishing hook 28 is angled in the direction of the first leg 32 in the region of its free end.
  • the angled part of the second leg 34 forms a downwardly oriented catch surface 36, which extends at a position parallel to catch hook 28 substantially parallel to the angled end portion 26 of the rotary latch 10 located in its open position.

  • the angled end portion 26 of the lower leg 24 of the catch engages the locking element 66 of the catch hook 28 (Fig. 5), whereby the catch hook 28 in turn is rotated counterclockwise (Fig. 6) until the angled end portion 26 of Rotary latch 10 has moved past the blocking element 66 and the rotary latch 10 reaches its locking position.
  • the fishing hook 28 rotates due to the restoring force of the second spring back into its catch position, in which the locking element 66 locks the catch 10 in the locked position (Fig. 7). The lock is now securely locked.
  • a vehicle occupant actuates an actuating element located, for example, in the vehicle interior, which is coupled to the catch hook 28 via the traction means 64.
  • the operation of the actuating element causes a first voltage of the traction means 64 (first stroke), which leads to a rotation of the lever 40 until the second stop 58 of the lever 40 engages with the pin 60 of the fishing hook 28, and then in a Rotation of the catch hook 28 in the release position (Fig. 8) results.
  • the locking element 66 and the rotary latch 10 are thereby disengaged, so that the rotary latch 10 driven by the first return spring can unscrew until the blocking projection 70 of the rotary latch 10 with the blocking element 68 of the catch hook 28 engages, causing the rotary latch 10 in an intermediate position is blocked, in which the striker 18 is still held securely in the mouth 16 of the rotary latch 10 (Fig. 9).
