Definitions
- the invention relates to a device for manually actuating a locking system, in particular at least one hood or flap lock, having a manual actuating means, a Bowden cable connected to the actuating means, at least one locking system connected to the Bowden cable and a means for locking actuation of the Bowden cable.
- Today's vehicles are usually seen ver with a central locking system.
- the opening mechanisms of the locking systems are usually interrupted and/or disabled by means of an electric drive.
- These central locking devices relate primarily to door locks, since the doors must be secured against unauthorized operation.
- bonnet or tailgate locks that can be operated remotely using a Bowden cable are now also in use.
- a bonnet lock for a bonnet or a tailgate lock for a trunk can be mentioned here as an example.
- hoods or flaps that can be operated remotely by means of a Bowden cable and are also to be protected from unauthorized access are also used in automobiles with electric drives.
- various approaches have become known.
- EP 0 153 978 B1 discloses an anti-theft system for locking manual actuation of a Bowden cable.
- a Bowden cable is arranged between a handle and a locking system.
- An anti-theft device was inserted into the Bowden cable in such a way that a clip was mounted on the Bowden cable core, with the clip being able to move with the Bowden cable core when the Bowden cable is operated manually.
- the one integrated into the Bowden cable The device has a housing through which the Bowden cable core is passed and the clamp is arranged inside the housing.
- a plate-shaped element can be guided over the Bowden cable core by means of an electric drive, so that movement of the clamp, which is firmly connected to the Bowden cable core, can be prevented.
- the locking element can thus prevent an actuation of the Bowden cable and thus an opening of the locking system.
- a comparable safety system for blocking movement of a cable train is known from US Pat. No. 4,099,593.
- the movement of a cable can be blocked by pivoting a locking plate.
- a clamp element is arranged on the cable pull, which is surrounded by the closing element and prevented from moving.
- the security systems known from the prior art can in principle prevent unauthorized operation of a cable or Bowden cable.
- the locking systems have a weakness, namely when, for example, the clamp mounted on the cable or the Bowden cable core cannot withstand a tensile load or the clamp element comes loose due to aging.
- the clip can be held, but the cable or Bowden cable can still be actuated. Increased forces acting on the cable or Bowden cable could also cause the clip to move on the cable or the Bowden cable core clip.
- the object of the invention is therefore to provide an improved security system for locking a manually operated locking system.
- the object is achieved according to the invention by the features of the inde pendent claim 1.
- Advantageous refinements of the invention are specified in the dependent claims. It is pointed out that the exemplary embodiments described below are not restrictive; rather, any possible variations of the features described in the description, the drawings, the subclaims and the exemplary embodiments are possible.
- the object of the invention is achieved in that a device for manually actuating a locking system, in particular at least one hood or flap lock, is provided, having a manual actuating means, a Bowden cable connected to the actuating means, at least one connected to the Bowden cable connected locking system and a means for locking an actuation of the Bowden cable, wherein a continuous connection of an actuation of the Bowden cable can be separated.
- the design of the device for manually actuating a locking system now makes it possible to securely lock the locking system, since the Bowden cable can be gripped and actuated by separating the continuous connection of the Bowden cable, but by preventing or Separation of the Bowden cable leads to actuation of the Bowden cable but not to opening of the locking system.
- the separation also simultaneously overcomes the problem that, despite the safety system, opening is possible due to excessive force.
- the separate Bowden cable can be actuated, the connection to the locking system is interrupted, so that the locking system can be effectively prevented from being opened.
- the device for manually actuating a locking system relates to locking systems such as those used in bonnets, flaps or lids or covers. This applies to covers, for example for convertible tops, flaps for trunks or tailgates for motor vehicles, to name just a few.
- the solution according to the invention includes such locking systems that can be operated remotely by means of a Bowden cable.
- These locking systems are actuated or opened by means of an actuating means, such as a handle, and in turn, for example, by means of a handle arranged in the passenger compartment.
- Such actuating means are known, for example for opening an engine hood, with the actuating means being arranged as a pivotable handle mostly in the area of the vehicle driver.
- the actuating means can also be arranged, for example, in the trunk, where various states prescribe such manual actuation of a trunk from the inside.
- two Bowden cables can also be connected to the locking system via a Bowden cable switch or a connecting element.
- the actuating means is preferably a lever arranged pivotably in the motor vehicle, but can also be, for example, a linearly actuated handle or an eyelet.
- the Bowden cable extends from the locking system to the actuating means and connects the actuating means to the locking system, so that when the actuating means is actuated, power can be transmitted to the locking system.
- the Bowden cable is then connected to a release lever or perhaps even to the pawl of a locking mechanism itself. If, for example, a release lever in the locking system is actuated by means of the Bowden cable, an existing locking mechanism is unlocked, so that a lock holder held by means of the locking mechanism can be released.
- the Bowden cable is consequently connected to the locking system on one side and to the actuating means on the opposite side.
- the means for locking is integrated into the Bowden cable between these connection points from the locking system to the actuating means.
- the Bowden cable is also disconnected in the means for locking.
- a mechanism arranged in the middle for locking makes it possible for the continuous connection of the Bowden cable to be separable. Consequently, in the disconnected state, power transmission from the actuating means to the locking system is interrupted, that is to say disconnected.
- the bow According to the idea of the invention, denzug is in two parts. A first section of the Bowden cable connects the locking system with the means for locking rules and a second section of the Bowden cable connects the actuating means with the means for locking. A connecting element is used according to the invention for separating the Bowden cable.
- the means for locking preferably has a housing, with the connecting element being accommodated and movably mounted in the housing. The first and second part of the Bowden cable extends into the housing at the endsei tig, the Bowden cable jacket being present in each case in a fixed manner in the housing.
- the Bowden cable cores are each connected to the connecting element or are suspended in the connecting element by means of a Bowden cable nipple.
- the connecting element thus connects the first section to the second section of the Bowden cable, so that a continuous power transmission via the Bowden cable is possible.
- the connecting element serves as a release agent.
- the locking element can thus advantageously consist of two separate connectors, the connectors each receiving, for example, a free end of the first and second section of the Bowden cable.
- a first connector accommodates, for example, a Bowden cable nipple of the first section of the Bowden cable
- a second connector accommodates, for example, a Bowden cable nipple of the second Bowden cable section.
- the connectors of the connec tion element thus serve as a receptacle for the Bowden cable core, with the con binders preferably being slidably received in the housing of the locking device or the means for locking.
- the connectors are advantageously connected to one another in a detachable manner.
- the connectors are preferably equipped in such a way that a form-fitting interlocking of the first and second connector is possible.
- the first connector has, for example, a recess into which the second connector can be inserted.
- the first connector offers a possibility of providing a receptacle for the second connector.
- the second connector can then be pivotally received in the housing, for example, thereby enabling the connectors to be disconnected.
- the second connector can, for example, be pivoted out of its longitudinal guide so that it can be separated.
- the second connector can have, for example, a hook, a cylindrical shape or a comparable shape, which can then be inserted into the receptacle of the first connector.
- the second connector can then be disengaged from the first connector, for example driven by a motor.
- the separation can advantageously be carried out by an electric motor.
- an electric motor drive By using an electric motor drive, the locking device can be controlled easily and safely.
- the disconnection can be controlled by the operator himself or can be integrated into a central locking device.
- An electric motor is preferably used, which can be engaged directly or indirectly with the connector. This means that locking can also be carried out very quickly.
- At least one motorized transmission unit can preferably be provided, with the motorized transmission unit enabling direct or indirect actuation of the connector.
- the connector or at least part of the connector can engage directly in a gearing of a gear unit or be driven indirectly by the gear unit.
- the connector can be connectable by means of a coupling element.
- the coupling element acts as a link between the first connector and the second connector and thus enables the Bowden cable connection to be mechanically separated.
- the use of a coupling element makes it possible to leave the connector or the parts of the connector in the starting position, so that the connector can be separated and guided securely and evenly in the housing of the locking device.
- the coupling element is here by means of the motor transmission unit Can be moved out of engagement with the connecting bolt by an electric motor.
- the coupling element can be inserted into the two parts of the connector in a form-fitting manner, for example.
- the coupling element is preferably guided linearly in the housing and engages, for example, in corresponding recesses in the connector elements.
- At least part of the connector can have a guide for the coupling element, so that the coupling element can only be detached from the engagement of a part of the connector in order to prevent the power transmission from being disconnected by means of the Bowden cable. If a positive connection is also realized between the first and second connector, the connector halves remain positively engaged even if the flow of force is separated, which in turn ensures a high level of functional reliability.
- a connector can extend through the second connector, where the second connector positively receives the first connector and provides a bearing for the first connector.
- the second connector is linearly storable in the first connector.
- the connectors can consequently be nested, which in turn enables the connectors to be securely connected to one another.
- the first connector can have a guide groove for the coupling element.
- the coupling element is then slidably received in the guide groove and can be moved in the guide groove by means of the electric motor drive for coupling and coupling.
- the connectors can be slid into one another. If there is a corresponding match, ie the position of the connector to one another, the coupling element can be moved back and forth in the guide groove, as a result of which it is possible to engage and disengage.
- the coupling element can be guided in a housing of the device.
- the coupling element connects the first and second connector, the coupling element being slidably received in a guide groove in the first and/or second connector.
- the coupling element has an extension that protrudes at least as far into the first and second connectors that a secure coupling of the connectors is possible.
- the extension on the coupling element can now be formed so far that the extension protrudes through the connector and can engage in the housing of the device.
- the coupling element can be guided in the guide groove of the connector, but at the same time there is the possibility of using the housing of the device itself as a guide means for the coupling element.
- the coupling element can be given an additional guide in the housing.
- the coupling element can also be guided on both sides in the housing. Due to the additional guidance in the housing, the connectors can also be aligned with one another, for example when the coupling element is engaged, which in turn makes it possible to align the connectors with one another reliably.
- a control lever can be actuated by means of the electromotive drive, with the coupling element being able to be actuated by means of the control lever, an advantageous embodiment of the invention can again be achieved.
- a transmission unit can be provided with the translation ratios can be realized, which Kings also initiate large forces in the connector.
- the coupling element connects the components of the connector, and the coupling element can also jam between the two connector parts.
- a large moment can be set and introduced into the coupling lever by using a control lever in combination with a drive wheel.
- the coupling element can be actuated by means of a motor-gear unit.
- An electric motor with a pinion and a gear wheel, in particular a worm and a worm wheel, arranged on the drive shaft of the electric motor can serve as the motor/gear unit.
- the worm wheel can have an actuating contour that can be brought into engagement with the control lever that is pivotably mounted in the housing.
- a rotational movement of the electric motor can be transmitted to the transmission via the worm gear and via the gear to the control lever.
- the control lever then interacts directly with the clutch lever, the clutch lever being guided, for example, in a connector part.
- a guide groove in the control lever allows the coupling element to be released safely and evenly from engagement with the connector.
- control lever can be loaded by means of a spring element, in particular can be preloaded, then an advantageous embodiment variant can in turn be provided.
- the spring element is accommodated in the housing of the locking means and loads at least the control lever in such a way that the control lever is spring-biased in the direction of engaging the clutch element. This ensures that the coupling element is engaged at all times and in particular when the locking device is in a non-energized state.
- the spring element can have a first spring leg which is in engagement with the control lever and have a second spring leg which is arranged in the locking unit in such a way that the worm wheel is also spring-loaded. The other spring leg is arranged in such a way that the worm wheel is spring-loaded in its end positions.
- End positions of the worm wheel here means that the worm wheel can be moved into two end positions by means of the electric motor.
- the spring element loads the worm wheel in such a way that the worm wheel can be held in the end positions. This can be done, for example, by arranging the spring's cle approximately parallel to the worm of the drive, with the worm wheel itself having a contour formed which can be brought into engagement with the spring limb.
- the control lever is constructed in two parts, with the parts of the control lever being able to be pretensioned by means of a spring element, in particular can be pretensioned against one another, a further embodiment variant of the invention can be provided.
- Dividing the control lever into two components which are biased towards each other by means of a spring element makes it possible to store a disengagement in the device.
- the operator's control command for locking can be temporarily stored in the device. If, for example, the Bowden cable is pulled and at the same time a locking command is forwarded to the device by the operator, the coupling element is under pretension between the connectors and cannot disengage. Disengagement can also be prevented by guiding the coupling element in the housing of the device when the Bowden cable is moving.
- the motor gear unit acts on the control lever and pivots a first part of the control lever.
- the spring element in particular a spring's, is prestressed, so that the second part of the control lever is under increased load from the leg spring. If the Bowden cable now reaches its starting position and thus also the connector in its starting position, the second part of the control lever can be pivoted and the coupling element can be moved out of engagement with the connector.
- the locking of the device initialized during actuation of the Bowden cable, can thus take place after the Bowden cable has reached its starting position. As a result, locking was temporarily stored while the Bowden cable was being actuated.
- the control lever can be mounted on an axis in the device and in particular on an axis provided by the housing of the device. Both constituent parts of the control lever can be pivoted about a common axis and are biased against one another by means of the spring element or the torsion spring.
- the control lever can be actuated by means of the motor gear unit, the motor gear unit having a gear element, in particular a worm wheel, and the control lever being actuatable by means of the gear element.
- the device is preferably equipped with a worm gear. on the output shaft of the motor, a worm is arranged, which is engaged with a worm wheel.
- the worm wheel itself is rotatably mounted on an axle in the housing of the device.
- the worm gear engages in the worm and, on the other hand, the worm gear has a control contour that engages with the first part of the control lever.
- the control lever can be actuated via the worm wheel and the control contour.
- a very fast movement can be initialized by the motor-gear unit and a transmission ratio can be realized via the gear stage and the control contour and the control lever, which provides sufficient force for actuating the clutch lever.
- a blocking lever is provided in the device, wherein a movement of at least part of the connector can be prevented by means of the blocking lever.
- a locking lever can further increase the functionality of the device and introduce an additional security feature into the device.
- the blocking lever acts together with the connector, or with at least one part of the connector. A movement of the connector can be blocked by means of the blocking lever in order to prevent multiple actuation of the Bowden cable. If, for example, the Bowden cable is pulled once and a hood lock is opened, for example, a second immediately following actuation of the Bowden cable to the hood lock can be prevented by means of the blocking lever.
- the lock When the Bowden cable is actuated for the first time, the lock is opened, with the connector being moved from the starting position to the end position in the device. In the end position, the blocking lever can engage with the connector and thus hold the connector in the end position and block movement of the connector.
- the motor-gear unit in the device receives a control signal, which drives the gear element and releases the blocking lever.
- the blocking lever can engage with the connector and thus blocking of the connector made union possible. Only after a further movement of the gear element is the blocking lever moved back into its initial position, so that the connector can be released is.
- the connector can be moved back to the starting position.
- the gear element can take on a dual function, namely on the one hand make the actuation of the control lever and on the other hand control the engagement of the blocking lever.
- the force of a spring element in the housing of the device can be adjusted.
- a spring element By introducing a spring element into the device and as a spring element, which acts against the connector, an effective return of the connector to the starting position can be supported and provided.
- the connector is preferably arranged linearly displaceable or adjustable in the housing.
- a spring element which is supported on the housing of the device and acts against the connector or bears directly against the connector, can make it easier to reset the connector.
- two Bowden cables can be hung in at least one connector.
- a second Bowden cable in the direction of, for example, another actuator The means of approval can be used, for example, to ensure that an emergency actuation can be arranged in a trunk.
- a second Bowden cable which can be hooked into at least one connector, can also be connected to a further locking system, so that two locking systems can be unlocked with the actuating means.

- the control lever 14 has a guide groove 25, so that the coupling element 15 can be actuated by means of the control lever 14 and can be guided linearly through the first connector part 18.
- the control lever 14 is prestressed in the position shown in FIG. 1 by means of the spring element 17 . That is, the control lever 14 is acted upon in the counterclockwise direction about the axis 24 with a biasing force.
- Another spring arm 26 of the torsion spring 17 is held essentially parallel to the worm 21 in the housing 2 .
- the spring leg 26 interacts with a contour 27 on the worm wheel 22 so that the worm wheel 22 is again subjected to a counterclockwise force by the spring element 17 . It can thus be ensured that the worm wheel 22 remains securely in its starting position as long as the transmission unit 12 is not activated.
- the unlocked state is shown in FIG. 1, ie when the actuating means 7, 8 is actuated, the locking system 4 can be actuated via the Bowden cables 5 and 3 and/or 6 and 3.

- FIG. 2 now shows the locked state of the locking device 1 again.
- the Bowden cable core 30 When the actuating means 7 is actuated, the Bowden cable core 30 would thus introduce a force into the second connector part 19 via the Bowden cable nipple 31, but the connector part 19 would only be moved alone, and a power transmission to the first connector part 18 would be interrupted.
- the connector parts 18, 19 of the connector 16 and the clutch lever 15 are reproduced as separate components and detached from the locking device 1 as. It can be clearly seen that the coupling element 15 is linearly guided in a guide groove 32 of the first connector part 18 .
- FIG. 3 shows the locked state of the locking device 1.
- the first connector part 18 serves as a linear guide for the second connector part, so that the connector parts 18, 19 are reliably guided relative to one another at all times.
- the second connector part 19 can thus be guided along a center line M in the first connector part 18 .
- Secure locking and unlocking by means of the locking device 1 can thus be implemented.
- the locking position of the coupling element 15 or the locking state of the locking device 1 can be detected via the switching means 13, which is designed as a microswitch 13 in the present exemplary embodiment.
- an extension 33 accesses the Microswitch 13, as shown in FIG.

- the connector 36 was moved in the direction of the arrow P2 by means of a Bow den cable, not shown, so that a locking system 4, as described above, can be unlocked.
- the clutch lever is in the unlocked position so that the first and second connector parts 38, 42 allow power to be transmitted to the locking system 4.
- the locked state of the locking device 34 is now shown in FIG.
- the electromotive gear unit 50 was acted upon by a control command, so that the worm wheel 51 was moved in a clockwise direction. Moving the worm wheel 51 causes the control contour 52 to move the control lever 41 clockwise and the clutch lever 40 to disengage the connector 36 .
- the guide groove 56 in the first connector part 38 and the form-fitting receptacle 57 in the second connector part 42 can be clearly seen. Operating the connector part 42 therefore does not unlock the locking system 4.

- the locking system 4 is unlocked, whereby a control signal is sent to the locking device 34, and the worm wheel 51 is driven clockwise.
- a cylindrical pin 58 of the blocking lever 54 is released, since the actuating contour 53 is also moved by the movement of the worm wheel 51.
- the blocking lever 54 is now able to reach behind a folded contour 59 of the connector 36 and to block repeated actuation of the connector 36 .
- FIG. 8 shows the locking device 34 in an actuated position of the connector 36. If, in the actuated position of the connector 36, an unlocking command is sent to the locking device 34, the worm wheel 51 is moved clockwise around and a part 45 of the control lever 41 is biased against the force of the spring 46. Since the clutch lever is under tension from the connector 36 and/or a guide groove in the housing 35, locking cannot take place. The actuation of the control lever 41 is stored as a movement in part 45 of the control lever 41, so that after the connector 36 has been returned to its initial position, the control lever 41 is able to move the coupling element 40 out of engagement with the connector 36.
