Definitions

  • the present patent application for industrial invention relates to an improved lock, having its main application in the automotive sector, in particular to close back doors of vehicles.
  • the lock of the invention is of the type comprising a disk rotating around a support pin and provided with a hook-like striker, adapted to hook, when closing the back door of the vehicle, on a projection suitably provided on the internal side of the edge of the compartment against which the back door is engaged at the end of the closing travel.
  • At least one retention tooth is obtained, adapted to cooperate with a catch composed of a rocker lever pivoted at one end to a fixed pin provided on the frame of the lock.
  • Said catch is subject to the action of a return spring that constantly pushes it against the edge of the disk, which is in turn subject to the action of a spring that tends to drive it into rotation in a direction corresponding to the release of the hook-like striker from said projection, with consequent opening of the lock and lifting of the back door.
  • the free end of said catch is coupled with the opening device of the back door, which is entrusted with the task of moving said catch - overcoming the resistance offered by its return spring - in such a way to make it oscillate in a direction corresponding to its movement away from the disk.
  • the free end of said catch is coupled with an actuation cable that can be tensioned by means of an opening lever of the back door situated in the driver and passenger compartment.
  • the free end of said catch is coupled with a slide moved by an electrical motor, with interposition of a gear assembly, the starting of which is determined by using a control button situated in the driver and passenger compartment.
  • the starting of said electrical motor determines the automatic opening of the lock, said slide being translated in such a direction to move said catch away from said disk, releasing said retention tooth from said hook, with consequent movement of the disk to end-of-travel position that corresponds to the opening of the lock.
  • the purpose of the present invention is to find a remedy to the aforementioned drawback.
  • a further purpose of the invention is to find a remedy to the problem by introducing simple improvements, leaving the structural configuration and operating principle of this type of locks unchanged.
  • An additional purpose of the invention is to adopt improvements that are reliable, simple and inexpensive to make.
  • the lock of the invention is characterized by the fact it comprises a memory lever, free to oscillate around a pivoting pin, so as to oscillate between two end-of-travel positions, wherein it has a practically sub-horizontal position, substantially orthogonal to the longitudinal axis of the catch.
  • the free end of said memory lever is interfaced with the free end of the catch, determining or not the stop position during its approach travel to the disk.
  • Said memory lever is provided, at approximately half of its length, with a lower leg, the rounded foot of which interacts with the edge of the disk, which has a cam profile, adapted to determine the oscillation of the maneuvering lever during the rotation of the disk around its pivoting pin, so that it can be said that the position taken from time to time by the memory lever is in turn determined by the position taken by said disk with hook-like striker.
  • the lock of the invention comprises a ratchet mechanism (A) contained in a box (S) closed by a lid (B).
  • Said ratchet mechanism (A) uses a catch (1), consisting in a lever pivoted at one (1 a) of its ends at a fixed pin (2), whereas at the other end (1 b) said lever (1) is associated with the opening device of the back door, not shown in the figure.
  • Said ratchet mechanism (A) also comprises a disk (4) rotating in idle around a support pin (5) parallel to said fixed pin (2).
  • Said disk (4) is provided with a hook-like striker (6) adapted to be coupled with a projection (7) during the closing of the lock.
  • At least one tooth (8) is obtained along the external edge of said disk (4), adapted to cooperate with a counter-tooth (9) obtained on the catch (1), which is subject to the action of a return spring, not shown in the figure, which constantly pushes it against the edge of the disk (4), which is in turn subject to the action of its own return spring that tends to drive it into rotation around its pin (5) in the direction - indicated by arrow (F) in Fig. 1 - that corresponds to the release of said hook-like striker (6) from said projection (7), with consequent opening of the lock and automatic lifting of the back door by means of traditional pushers designed to favor the opening of the back door.
  • the lock of the invention is characterized by the fact that it comprises a memory lever (10) free to oscillate around a pivoting pin (11), situated at one (10a) of the two ends (10a and 10b) of the lever (10).
  • Said pin (11) is parallel to the other two pins (2 and 5) and the three pins (2, 5 and 11) are permanently fixed inside said box (S), as shown in Figs. 6 and 7 .
  • Said memory lever (10) oscillates between two end-of-travel positions, in which it has a practically sub-horizontal position, substantially orthogonal to the longitudinal axis of the catch (1), as shown by comparing Figs. 1 to 5 .
  • the other end (10b) of said memory lever (10) is interfaced with the free end (1 b) of the catch (1), determining or not the stop position during the approach travel to the disk (4) .
  • Said memory lever (10) is provided, at approximately half of its length, with a lower leg (10c), the rounded foot of which (10d) interacts with the edge of the disk (4), having a cam profile (4a), determining the upward oscillation and favor the downward oscillation of the maneuvering lever (10) during the rotation of the disk (4) around the pivoting pin (5).
  • the memory lever (10) is subject to the action of its own return spring, not shown in the figures, which pushes it constantly against the disk (4) .
  • Figure 1 shows the position of the kinematic parts of the lock of the invention, when the back door is closed and the lock is in closing position.
  • the opening rotation of the disk (4) is opposed by the fact that the tooth (8) is coupled with the counter-tooth (9) of the catch (1), which is pressed against the disk (4) by the return spring that actuates on catch (1).
  • the memory lever (10) is inactive with respect to said catch (1), given the fact that its end (10b) surmounts and rests above the end (1 b) of the catch, without interfering with the oscillation of the catch away from the disk (4).
  • the disk (4) oscillates until it reaches its end-of-travel position, which corresponds with the complete release of the projection (7) from the hook-like striker (6), as shown in Fig. 5 .
  • Fig. 5 shows that the lock has moved away from the projection (7), which is fixed to the boot compartment, whereas the lock follows the opening movement of the back door, being mounted on board the same back door.
  • the disk (4) cannot oscillate and remains in its initial position, as shown in Fig. 2 , in spite of the fact that the catch (1) is at maximum distance from the disk (4), further to actuation of the opening device of the back door.
  • This new position of the memory lever (10) prevents a new oscillating travel of the catch (1) approaching the disk (4), which would occur automatically - because of said return spring assisting the catch (1) - as soon as the action exerted on the catch by the opening device of the back door ends.
  • the back door can be lifted and opened manually, overcoming only the load that is accidentally applied on the back door, given the fact that the tooth (8) of the disk (4) and the counter-tooth (9) of the catch (1) are not momentarily coupled, as shown in Fig. 3 .
