Description

AUTOMOBILE VEHICLE DOOR CLOSURE THAT CAN BE HANDLED BY HAND OR THROUGH A CENTRALIZED LOCKING DEVICE AND PRESENTING AN ANTI-THEFT INSURANCE DEVICE.

The invention concerns a door closure of a motor vehicle which can be operated by hand or by means of a central locking device and which has an anti-theft device, including a rotary slide, a locking pawl, a locking lever which acts directly or indirectly on the locking pawl, an external locking lever acting on the locking lever, an inner locking lever acting on the locking lever, an inner operating lever and idling devices on the lever internal interlock and in the inner operating lever, and including a quadrupole planetary gear with central wheel, planet carriers, satellites and hollow wheel with which the satellites mesh, the central wheel being operated by a single electric motor that can be turned to the left or turn to the right, and an activated part of enclave is provided and an activated part of the anti-theft device, in which the activated locking part is derived from the planet carrier and has a drive disk which is arranged on a locking shaft running parallel to the central wheel shaft and is intended to actuate the lever of interlocking, and that can be dragged back and forth, through a system of elongated bolt / hole, by the planet carrier between the positions of polarization "locked" and "unlocked" according to the direction of rotation of the electric motor, in wherein the actuated portion of the anti-theft lock is derived from the hollow wheel and has a toothed wheel segment which is arranged on a shaft of the anti-theft safety device which runs parallel to the central wheel shaft and is intended to actuate the anti-theft safety lever, and which can be drawn back and forth by an outer toothed ring of the hollow wheel between the polarization positions "secured against theft" and "not secured against theft "in accordance with the direction of rotation of the electric motor, wherein a locking mechanism has been provided between the actuated part of the interlock and the actuated part of the anti-theft lock, and wherein the arrangement has been chosen so that in the fixed polarization position "secured against theft" a component of the locking mechanism positively or directly blocks the planet carrier of the actuated locking part. The known vehicle door lock from which the invention starts (DE 43 34 522 Cl) has given good results in practice. In this door closure of a motor vehicle, an emergency unlocking device has been implemented, such as in functionally similar vehicle door locks, for example in the event that the drive by electric motor has failed. Emergency unlocking means that, in the event of failure of the power supply for the operation of the central locking, it must also be possible to unlock manually by means of the lock bulb with the associated key, and especially to get out of the polarization position "secured against theft". This is also possible in the known embodiment. To this end, the external interlocking lever is equipped with an arm that moves the anti-theft lock lever from the "secured against theft" position to the "uninsured against theft" position. This emergency maneuver is difficult to carry out. The invention is based on the technical problem of facilitating the emergency unlocking maneuver in a motor vehicle door closure of the structure described at the beginning. To solve this problem, the invention, starting from the known motor vehicle door lock described at the beginning, provides the teaching that the anti-theft insurance lever is combined with the anti-theft safety shaft through a kinematic force connection, the anti-theft safety lever can be moved with the help of the quadrupole planetary gear together with the activated part of the anti-theft lock , through the kinematic force connection, to the mechanical polarization positions "secured against theft" and "uninsured against theft", and, in addition, the anti-theft security lever can be moved by means of the external locking lever ( on which acts, for example, the lock bulb of the door lock of a motor vehicle), overcoming the force kinematic connection and avoiding the quadrupole planetary gear and its drive, from the polarization position "secured against theft" to the polarization position "not insured against theft". The force kinematic connection described can be embodied in different ways in the closing of a motor vehicle door according to the invention. According to a preferred embodiment of the invention, the maneréi arrangement has been chosen for the kinematic force connection to be established by means of a longitudinal groove of the anti-theft safety shaft and a rib of the gear segment which determines a bead Elastic for insertion and disengagement purposes. For this purpose, the toothed wheel segment can be constituted, at least by sectors, by an elastically movable plastic which has a cavity in the area located above the bead-like rib that determines the elastic mobility of said rib. The invention is based on the knowledge that in a motor vehicle door closure of the structure described at the outset it is hardly possible to replace the positive and therefore rigid connection between the anti-theft safety lever and the shaft of this safety device by a kinematic force connection that can be established without problems so that the anti-theft lock lever can be moved by electric motor, as described, to the mechanical polarization positions "secured against theft" and "not insured against theft", but that In addition, it can be easily moved by means of the external locking lever, on which it acts directly or indirectly, for example, the light bulb of the door lock of a motor vehicle, overcoming the force kinematic union and, therefore, , avoiding the quadrupole planetary gear and its drive, from the polarization position "secured against theft" to the polar position "unsecured against theft". It is also possible to proceed analogously to what is described in relation to the locking lever which is actuated by the locking shaft, the kinematic force connection operating in the manner described being arranged between the locking lever and the locking shaft. The invention is explained below in more detail with reference to a drawing representing only an exemplary embodiment. They show: FIG. 1, in schematic representation, a view of a motor vehicle door lock according to the invention, FIG. 2, a fragmentary view of the object of FIG. 1 taken from the A direction, FIG. 3, a view fragmentary of the object according to figure 1 in another operating position, figure 4, the scheme of a four-pole planetary gear according to the invention in a view of the satellites, figure 5, a section in the direction BB through the object of Figure 4, Figure 6, in a schematization corresponding to Figure 3, the position of polarization "secured against theft" with kinematic union of operating force, Figure 7, the object according to Figure 6 with kinematic union of force expired, Figures 8 to 10, on an enlarged scale compared to Figures 6 and 7, details of the force kinematic union, and Figures 11 and 12, corresponding to sections BC in Figure 9 and DE in figure 10, respectively, the constructive configuration of the force kinematic union. The motor vehicle door fastener shown in FIGS. 1 to 3 can be operated by hand or by means of a central locking device, and, in addition, has an anti-theft security device. The basic structure comprises, in the first place, a pivoting slide 1, a locking pawl 2, a locking lever 3 acting directly or indirectly on the locking pawl 2, an external locking lever 4 acting on the lever of locking 3, an inner locking lever 5 acting on the locking lever 3, and an inner operating lever 6. Otherwise, usual devices for idle running on the inner locking lever 5 and on the lever are embodied of internal drive 6, which do not require any special explanation. A quadrupole planetary gear 7, which is specially configured and to which a special function is assigned, is provided in the motor vehicle door lock. While Figures 1 and 3 show the quadrupole planetary gear 7 in a schematized form without the construction details, the basic structure thereof can be seen in Figure 4. Part of the quadrupole planetary gear 7 is a central wheel 8, a satellite carrier 9, satellites 10 and a hollow wheel 11 with which the satellites mesh. The central wheel 8 is driven by a single electric motor 12 which can be turned to the left or to the left. right. The quadrupole planetary gear 7 has an actuated locking part 13 and an actuated part 14 of the anti-theft lock. In FIG. 4, the polarization positions I to IV of the motor vehicle door lock, which are explained below, are also shown. The actuated locking part 13 is derived from the planet carrier 9 and has the mechanical locking positions "locked" (I) and "unlocked" (II), with respect to which the reader is referred to figures 4 and 6. The driven part 14 of the anti-theft insurance is derived from the hollow wheel 11 and presents the mechanical polarization positions "secured against theft" (III) and "uninsured against theft" (IV). Reference is also made here to the reader in particular to FIG. 4. Between the activated locking part 13 and the driven part 14 of the anti-theft device, a locking mechanism 15 is provided. This is shown in FIG. 4. The arrangement has been chosen in such a way that that in the polarization position "secured against theft" (III) a component of the locking mechanism, namely the tongue 16 of that mechanism, positively blocks the planet carrier 9 of the actuated locking part 13. The actuated locking part 13 is provided with a driving disk 17 which is arranged on a locking shaft 18 which runs parallel to the shaft of the central wheel 8 and is intended to directly or indirectly actuate the locking lever 3, and which can be driven back and forth by means of the elongated bolt / hole system 19a, 19b by the planet carrier 9 between the "locked" (I) and "unlocked" (II) polarization positions in accordance with the direction of rotation of the electric motor 12. In the exemplary embodiment and according to a preferred embodiment of the invention, the driven part 14 of the anti-theft device has a gear segment 19 which is arranged on a shaft 20 of the anti-theft safety device. which runs parallel to the axle of the central wheel 8 and is intended to directly or indirectly actuate the lever 21 of the anti-theft lock, and which can be driven back and forth by an outer toothed crown 24 of the hollow wheel 11 between the polarization position "secured" against theft "(III) and" uninsured against theft "(IV) in accordance with the direction of rotation of the electric motor 12. The satellite carrier 9 has a recess 23 for the locking mechanism in which, in the polarization position "secured against theft" (III), engages the tongue (16) of the locking mechanism of the gear segment 19, which has a complementary shape to said recess 23. The "locked" polarization positions (I) and "unlocked" (II), as well as "insured against theft" (III) and "not insured against theft" (IV), are configured as stops in the quadrupole 7 planetary gear and / or in the plate or in the casing of the lock, which has been indicated only schematically. Figure 1 shows the locked position (I) of the motor vehicle door lock. The electric motor 2 and the planet carrier 9 are stopped. The planet carrier 9 stops when the driving bolt 19a stops on the driving disk 17. The electric motor 12 is stopped by means of the switch 24 visible in FIG. 1, the stopping being carried out specifically by means of a corresponding connection of the poles of the switch. 24. The recess 23 of the planet carrier 9 for the locking mechanism occupies, in the locked state of the motor vehicle door lock, a position that allows a free rotation movement of the gear wheel segment 19 with the driven part 14 of the anti-theft lock .

If electrical power is supplied to the switch 24 of FIG. 1 so that the electric motor is subjected to electrical voltage beyond the "locked" polarization position (I), then the hollow wheel 11 of the quadrupole planetary gear 7 is driven. because the planet carrier 9 is prevented from continuing to rotate by means of the pin 19a which is applied to the driving disk 17. Consequently, the recess 23 of the planet carrier 9 for the locking mechanism, as already noted above, is placed so that the gearwheel segment 19 can move freely rotating together with the driven part 14 of the anti-theft lock or with the corresponding shaft and is also actuated. The rotational movement of the gearwheel segment 19 develops to the polarization position "secured against theft" (III) and is stopped in this position by a stop. The. tab 16 of the locking mechanism of the gear segment 19 enters the recess 23 of the planet carrier 9 provided for said mechanism. In this way, the planet carrier 9 is blocked and a full or partial rotation thereof is no longer possible. This is important for the inverse development of the operation, that is, to move from the "secured against theft" position (III) of the motor vehicle door lock to the "unlocked" position.

(II) through the "locked" polarization position (I).

For the reverse development of the operation, some observations are sufficient: The electric motor 12 is supplied with current in the opposite direction of rotation and thus is driven accordingly. Since the planet carrier 9 is still blocked, the hollow wheel 11 and with it the gear wheel segment 19 are driven until said hollow wheel is applied to the stop for the polarization position "not insured against theft" (IV). Thereafter, the planet carrier 9 is driven with rotational movement due to the nature of the quadrupole planetary gear 7. The driving pin 19a enters the elongated open-edge hole 19b of the driving disk 17. This driving disk 17 is rotated until reaching the stop for the "unlocked" polarization position (II). The planet carrier 9 continues to rotate until the driving pin 19a abuts against the driving disk 17. The power supply to the electric motor 12 is switched off by means of a timed control system which has not been shown. The drag disk 17 can be moved freely by hand. Locking levers of the motor vehicle door lock are engaged in the actuated locking part 13 and in the actuated part 14 of the anti-theft device. The coupling is done in the corresponding trees. In the actuated locking part 13, a lever arm 25 with a fork opening 26 at the end of said arm is solidly fixed in rotation. In this fork opening 26 a bolt 27 which is fixedly connected with the locking lever 3 penetrates. Therefore, this locking lever 3 is moved by the driving disc 17 from an unlocked position (II) to a locked position (I). ), and vice versa. In the locked position (I) it is pivoted to a coupling lever 28 connected with bolt 29 to a position such that the bolt 29 is outside the range of action of the locking pawl 2 and, therefore, the lock can not be opened by means of the external operating lever 30. With the locking lever 3, a conventional external locking lever 4 is interconnected, which is connected to a lock bulb, for example by means of a rod 31, and a conventional inner locking lever 5. which is attached, for example, with an inner interlock button. The actuated portion 14 of the anti-theft device is connected with it, integrally in rotation, with a deflected arm 32 provided with a bend 33. In the "secured against theft" (III) position and in the functional sequence that occurs after reaching the position of the latch. interlocking (I), the elbow 33 is in front of the bolt 29 on the coupling lever 28 so that an unauthorized unlocking attempt through the inner locking lever 5 or the outer locking lever 4 does not lead to the coupling lever 28 it can be pivoted to the actuation area of the locking pawl 2. As a consequence, the motor vehicle door lock can not be opened. By itself alone is understood the way in which the door closure of a motor vehicle according to the invention passes, by means of the quadrupole planetary gear, from the polarization position "not insured against theft" (IV) to the position in which the Anti-theft insurance is no longer connected and, therefore, is no longer operational. In the above-described vehicle door lock described above, it is possible, according to the teachings of the invention, for a special emergency unlocking to exit the position (III) of the anti-theft lock. In figures 3, 4 and 5, as well as, in more detail, in figures 6 to 10 it can be seen that the lever 21 of the anti-theft safety device is joined to the shaft 20 of this safety device by means of a force kinematic connection 34. lever 21 of the anti-theft lock can be moved with the help of the quadrupole planetary gear 7, together with the driven part 14 of the anti-theft lock and through the force kinematic connection 34, to the mechanical polarization positions already described "secured against theft" (III ), as well as, reciprocally, "not insured against theft" (IV). Otherwise, the force kinematic connection 34 is designed so that the lever 21 of the anti-theft lock can be moved from the polarization position "secured against theft" (III) to the polarization position "not insured against theft" (IV ) by means of the external locking lever 4 on which the door lock of the motor vehicle door lock acts directly or indirectly, for example by overcoming the force kinematic connection 34 and, therefore, avoiding the quadrupole 7 planetary gear and its drive. In the exemplary embodiment and according to a preferred embodiment of the invention, the kinematic force connection 34 is materialized with the aid of a groove 35, a bead-like rib 36 and a cavity 37. The reader is also referred to FIGS. 11 and 12. The manner in which the force kinematics connection 34 is established with the help of the longitudinal groove 35 of the anti-theft safety shaft 20 and the rib 36 of the gear wheel segment 19 made is shown in the latter figures. as a heel that can move elastically for purposes of insertion and disengagement. For this purpose, the gear wheel segment 19 is constituted, at least by sectors, by an elastic plastic which has in the region located above the bead-like rib 36 the cavity 37 that determines the elastic mobility of said rib. 36
