Definitions
- the present patent application for industrial invention relates to an improved lock for car bonnets or doors.
- the lock of the invention is of the type provided with double stop tooth, capable of guaranteeing the stable, although partial, closing also in the case of a light force that is not sufficient to bring the bonnet at the end of the stroke overcoming the resistance to flattening offered by the seal gaskets against which the bonnet is closed.
- This type of locks is based on a mechanism that functions as a ratchet pawl, it being composed of a rotating hook disk, whose edge is provided with two stop teeth designed to co-operate with an oscillating ratchet pawl subject to the action of a spring that pushes it constantly against the edge of the disk.
- the hook disk is subject to the action of a return spring that tends to rotate it in a direction that corresponds to the release of the coupling tooth from the projection of the lock.
- the ratchet pawl engages with one of the two stop teeth, thus preventing the rotation of the disk and the opening of the lock.
- the lock can only be opened with the key or button that allow to disengage the ratchet pawl from the stop teeth, thus making the hook disk trip at the end of the opening stroke, under the action of the return spring.
- the presence of a pair of stop teeth instead of a single tooth is required to guarantee the stable, although partial closing of the lock when the closing force is not sufficient to elastically flatten the seal gaskets against which the bonnet is closed.
- the ratchet pawl could act as stop for the disk only when the disk is pushed at the end of its stroke as a result of a strong closing force on the bonnet.
- the presence of the second stop tooth allows to stop the disk as soon as the disk has made a small rotation that allows the hook tooth to engage with the projection of the lock.
- the problem has been solved by introducing a safety lever that intervenes during opening to interfere with the ratchet pawl, thus preventing it from engaging with the second stop tooth once the first stop tooth has been released.
- the safety lever basically acts as holding element that engages and holds the ratchet pawl only when the ratchet pawl reaches the farthest backward position with respect to the disk, which is provided with a special appendix capable of releasing the safety lever of the ratchet pawl as soon as the rotation of the disk starts when closing the lock.
- the purpose of the present invention is to solve the inconvenience by realising an improved version of the aforementioned type of car locks, in which the safety lever interferes with the ratchet pawl for the length of time that is necessary for the hook disk to complete its opening travel.
- the safety lever holds the ratchet pawl away from the hook disk until the second stop tooth has reached such a position that it can no longer be intercepted and engaged by the ratchet pawl when the ratchet pawl is free to get close to the edge of the hook disk.
- the lock of the invention comprises a disk (1) that rotates around a pivoting pin (2) and is peripherally equipped with a hook tooth (3) designed to engage the projection (4) when the car bonnet is closed.
- the external edge of the hook disk (1) features a first stop tooth (5) and a second stop tooth (6) designed to co-operate with a ratchet pawl (7) composed by a rocker level pivoted at one end on a fixed pin (8) of the lock.
- the lever has a special forked profile with the following components:
- the lock of the invention also comprises a safety level designed to interfere with the ratchet pawl during opening, in order to prevent it from engaging with the second stop tooth (6), once the first stop (tooth) has been released.
- the lock of the invention is characterised both by the profile of the safety lever and by the mechanism used to move the safety lever, which must be inactive when closing the lock and must be activated when opening the lock to remove the ratchet pawl (7) from the hook disk (1) until the hook disk (1) has reached the end of its opening stroke, which corresponds to the complete disengagement of the hook tooth (3) from the projection (4).
- the safety lever (10) has a pivoting hole (10a) at one end, while the other end finishes with a wedge-shaped head-cam (10b) that protrudes from one side only.
- the lever (10) is pivoted on the pin (8) in such a way that the head-cam (10b) faces the hook disk (1).
- the two opposite sides of the head-cam (10b) are in contact with two tappets (1a and 7d), which are located and protrude from the hook disk (1) and the ratchet pawl (7), respectively.
- the external side (L1 ) of the head-cam (10b) interferes with the tappet (7d) on the second section (7c) of the ratchet pawl (7), while the internal side (L2) of the head-cam (10b) interferes with the tappet (1a) on the edge of the hook disk (1).
- the tappet (1a) interferes with the internal side (L2) of the head-cam (10b), thus removing the safety lever (10) until the tappet (1a) engages against the head side (L3) of the head-cam (10b), after sliding along the internal side (L2).
- the removal of the lever (10) causes the simultaneous removal of the ratchet pawl (7) due to the interference between the external side (L1 ) of the head-cam (10b) and the tappet (7d).
- the head side (L3) of the head-cam (10b) has a chamfered edge (10c) that favours the sliding of the tappet (1a) under the head-cam (10b), with simultaneous complete rising of the lever (10) that, due to the action of the spring (10d), returns to its natural lowered position, as soon as the tappet (1a) faces the internal side (L2), as shown in fig. 6.
- the actuator In the enclosed figures number (11) is used to indicate the actuator designed to excite the opening force (FA) on the section (7b) of the ratchet pawl (7); in this specific case, the actuator consists in an electric motor that drags into rotation a screw (11a) coupled with a nut screw (11b) applied on the ratchet pawl (7).
