Definitions

  • the invention relates to a lock for a door or flap with a locking mechanism comprising a catch and a pawl for locking the catch.
  • a lock is from the DE 103 20 457 A1 known.
  • the invention further relates to a system comprising at least two such locks and a manufacturing method for a plurality of such locks.
  • An aforementioned lock is used for temporary closing of openings in motor vehicles or buildings by means of doors or flaps.
  • the rotary latch engages around a particular bow-shaped locking bolt, which is usually attached to the body in the case of a motor vehicle. If the rotary latch reaches a closed position by pivoting with the aid of the locking bolt, starting from an open position, the rotary latch is finally locked by means of the locking pawl. A locking surface of the pawl then abuts against a locking surface of the rotary latch, which prevents the rotary latch can be rotated back in the open position. The locking pin can not leave the locking mechanism in the closed position.
  • a sealing pressure of the corresponding door or flap or a prestressed spring may be responsible. Also, a pulling movement of the locking bolt out of the locking mechanism can cause such a rotation.
  • the lock may include a blocking lever that is capable of blocking a pawl when the pawl locks the catch. To open such a locking mechanism, the blocking lever must first be moved out of its blocking position.
  • the catch in the latched state can initiate an opening moment in the pawl.
  • the opening moment may cause the pawl to be moved out of its detent position.
  • unwanted moving out is prevented by a blocking lever. If the blocking lever is moved out of its blocking position, the lock then opens automatically.
  • a handle of a door or flap may be part of the actuator. This handle is usually connected via a linkage or a Bowden cable with an actuating lever of the castle. If the handle is actuated, the actuating lever of the lock is pivoted by means of the linkage or Bowden cable so that the lock opens.
  • Locks of motor vehicles are regularly equipped with a central locking system (see for example DE 41 08 561 A1 ) and / or an anti-theft device (see for example DE 10 2011 018 512 A1 ) fitted.
  • a central locking system see for example DE 41 08 561 A1
  • an anti-theft device see for example DE 10 2011 018 512 A1
  • To lock a side door lock and / or insert an anti-theft device corresponding mechanisms provided which generate a rotational or linear movement and thus lock the lock or unlock or insert the anti-theft device or release.
  • an adjustment of the lock or theft prevention should be avoided for safety reasons, so for example, the adjustment of a locked position in an unlocked position or in the case of an anti-theft adjustment from an inserted position to an unlocked position.
  • a leg of a spring In order to protect a latch or theft protection from changing its position in the event of a crash, it may be provided that a leg of a spring must be moved against a spring force of the spring to change the position of a lock or an anti-theft device can.
  • the greater the force that is then required for such a movement of a spring leg the greater the acceleration in a crash must be in order to change the position of an anti-theft device or a lock can.
  • the spring force can be achieved so that accelerations of, for example, up to 30 g or up to 55 g can not change the position of an anti-theft device or a central locking.
  • g is meant the gravitational acceleration.
  • the spring leg is the position assurance for securing the position of a lock or the position of an anti-theft device in the case of high accelerations, as they can occur in the event of a crash.
  • the position of a lock or an anti-theft device is regularly changed as needed by means of a motor.
  • the presence of a position assurance requires a corresponding engine power to overcome the position assurance, so in the example mentioned to move the spring leg.
  • US 2008 0 078 215 A1 describes a lock according to the preamble of claim 1.
  • DE 103 23 888 A1 and EP 2 330 266 A1 describe similar locks.
  • the invention provides a lock with a ratchet comprising a catch and a pawl for latching the catch.
  • the lock includes a position lock for a lock or anti-theft device.
  • a spring serves to secure the position.
  • the spring is designed as a double-sided forceps spring with two spring legs, which must be moved at the same time in order to change the position of the lock or anti-theft device.
  • a desired adjustment of the lock or theft protection can be advantageously carried out with less effort in the castle according to claim.
  • the comparison refers to the case that the respective position assurance has grown equal acceleration forces.
  • a stop for the spring legs of the pliers spring is provided, which limits the movement of the spring legs. This helps to be able to use a relatively weakly dimensioned spring, so a spring with a small spring constant, and yet to allow a position assurance that has grown even high accelerations of, for example, up to 30 g or up to 55 g.
  • a bolt for example, cylindrical pin
  • the lock or theft protection on which the pliers spring two-sided for a position backup works.
  • the bolt To change the position of the lock or anti-theft device, the bolt must be moved. It can be a relative movement. Such a movement counteract two legs of the pliers spring, which then abut the bolt. By such a movement of the bolt, the two legs of the tong spring are moved against a spring tension.
  • a position assurance is provided with little space and little technical effort.
  • the movement of the spring leg is limited to the outside by two walls which serve as the stop and limit the movement of the spring legs, which is effected by an adjustment of the bolt from a first rest position to a second rest position or vice versa. It is thus achieved that the bolt is secured against being adjusted at high accelerations without having to use excessively dimensioned springs, ie springs with large spring constants.
  • a spring in the sense of the present invention is also present when this is made in two parts. It is only essential that two legs are present, both of which must be moved simultaneously against a spring force to unlock or lock a lock or to change the position of an anti-theft device can. However, it is preferably a one-piece spring, As a result, the technical complexity for the production can be minimized.
  • a movement of a leg according to the invention is also present when a leg is not moved in total, but only a portion of a leg. Also, a deformation of a leg is thus a leg movement in the sense of the present invention.
  • the bolt is linearly moved in one embodiment for a change of a position of a lock or an anti-theft device or is linearly movable.
  • This embodiment enables a particularly reliable functioning of the position assurance.
  • a position assurance with a particularly small installation space can be provided in this way.
  • both ends of each leg are fixed. This advantageously contributes to using a weakly dimensioned spring, in order nevertheless to be able to provide a position assurance which is also able to cope with high accelerations.
  • a motor is provided with which the position of the lock or the position of the anti-theft device can be changed. Compared with the case where a one-way spring is used as a position lock, a comparatively low power motor can be used. This allows the use of a motor with comparatively small space and comparatively low weight. This will be the Overall space required in addition to weight and the technical complexity kept low.
  • an identical spring is always provided to provide a plurality of position fuses, which is preferably always mounted in the identical manner, so that spring voltages are always the same.
  • bolts or cylindrical pins with different diameters and / or differently shaped cross sections are used.
  • the forces which a position assurance can cope with can thus be adjusted with otherwise identical mechanics as a function of the requirement by selecting the bolt.
  • the FIG. 1 shows two double-acting forceps springs, each with two undulating spring legs 1.
  • the waveform of the legs 1 two positions are created for a bolt.
  • the bolt can be moved back and forth linearly between a position or position 2 and a position or position 3.
  • the legs 1 of each in the present case one-piece forceps spring in a central region between the two positions 2 and 3 have to be pressed apart against a spring tension.
  • a rest position 2, 3 of each bolt is secured by the two legs 1 of a spring.
  • the movement of the legs 1 is limited to the outside by walls 4, which serve as a stop. These limit the movement of the legs 1, which is effected by adjusting the position of a bolt from 2 to 3 or vice versa. It is thus achieved that a bolt is secured against displacement at high accelerations, without having to use excessively sized springs, so feathers with large spring constants.
  • Two walls 4 are parallel to each other and parallel to the longitudinal extension of the associated spring with the legs 1.
  • Two walls 5 serve to hold or fixing free ends of the legs 1.
  • a wall portion 6 between the two legs 1 of a spring in the free Ends also serves to hold or fix the free ends of the legs 1. In particular, the free ends of the legs 1 are held and fixed by the walls 5 and 6 positively and / or non-positively.
  • each one-piece spring which is opposite the free ends of the legs 1, extends in a circle around a pin 8 of the housing 9 around.
  • a laterally projecting from the bolt 8 web 10 helps to hold the end 7 of each spring positively.
  • the end 7 is also surrounded by a wall 11, which also contributes to a positive retention of the end 7 of each spring.
  • the end 7 is also fixed.
  • FIG. 1 an upper position assurance and a lower position assurance is shown. Mechanically, both position safeguards are identical in construction with the exception of the bolt.
  • the bolt of the upper position lock has a smaller diameter than the bolt of the lower position lock. Due to the smaller diameter is the upper position guard has grown lower acceleration forces compared to the lower position guard.
  • the in the FIG. 1 shown bolts have a circular diameter. These are cylindrical pins. Instead of a circular diameter, the diameter of a bolt for the aforementioned reasons, for example, triangular, semicircular or oval.
  • FIG. 2 show other embodiments of cross sections of bolts 9, which can be used alternatively in a position assurance. Shown is a triangular cross section, an oval cross section and a flattened circular shape. Depending on the shape, the dimensioning and the installation direction desired acceleration forces can be adjusted in a position assurance, which has grown a position assurance.
