Definitions
- Door lock in particular motor vehicle door lock
- the invention relates to a door lock, in particular a motor vehicle door lock, with a locking mechanism consisting essentially of a rotary latch and at least one locking pawl, furthermore with a lever chain for the direct or indirect actuation of the locking mechanism, the lever chain having at least one actuating lever and an actuated lever optionally actuated by the actuating lever, and with at least one damping element for the lever chain.
- Door locks and in particular motor vehicle door locks, are typically equipped with a single locking mechanism comprising a rotary latch and a pawl that secures the rotary latch.
- a single locking mechanism comprising a rotary latch and a pawl that secures the rotary latch.
- multiple ratchets or multi-ratchet ratchets are also considered, ie those that are equipped with a rotary latch and, for example, two ratchet pawls, a comfort pawl and a blocking pawl securing the comfort pawl.
- EP 1 500 762 B1 works with at least one stop surface on the edge of the rotary latch and / or pawl realized damping means.
- the damping center has a certain height compared to the associated stop surface.
- Particularly effective damping is achieved by the arrangement of the damping means chosen on the edge of the stop surface. This has basically proven itself.
- a comparable damping means for the locking mechanism of a door lock and in particular a motor vehicle door lock is described in WO 2006/133673 A1.
- the locking mechanism is equipped with at least one cam, which interacts with a friction brake device in the course of assuming the closed position.
- the cam and, if appropriate, the rotary latch are designed to be noise-damped in order to once again reduce the development of noise compared to previous designs with a simple structure.
- the aforementioned utility model describes a motor vehicle door lock with at least one locking lever that assumes at least the two functional positions “unlocked” and “locked”.
- a stop defining the respective functional position is provided. The stop is formed on a rubber-elastic buffer which is supported on a housing.
- the locking lever is specifically designed as an external locking lever and can be transferred into the previously mentioned functional positions, for example with the aid of a lock cylinder.
- the locking lever or external locking lever provides - indirectly - for the actuation of the locking mechanism, namely in the end in such a way that the locking lever “unlocks” an actuation of the in its position Locking mechanism (via an additional and then mechanically closed actuating lever chain) in particular allows opening, whereas the functional position "locked” corresponds to the fact that the lever chain or actuating lever chain in the example case to act on the locking mechanism typically frees up or is possibly blocked.
- the locking mechanism can in particular be opened with the aid of such a lever chain or actuating lever chain. This can be done manually using an inside or outside door handle. It is also possible to apply an electric motor to the operating lever chain. Since, in this context, individual or all levers of the lever chain may be heavily loaded, metal levers are usually used to implement the lever chain. These must not be coated on their contact surfaces in order to avoid wear and tear during the long service life. As a result, the previously mentioned “metallic noises” are possible when individual metal levers interact with one another. These occur, for example, when individual levers suddenly move away from one another, but are nevertheless elastically connected to one another via a spring coupling them, so that a "rebound” and the annoying metallic noises occur in the area of their metallic contact surfaces. Such a noise development is not effectively attenuated by the prior art available to date. This is where the invention comes in.
- the invention is based on the technical problem of further developing such a door lock and in particular a motor vehicle door lock in such a way that particularly effective noise damping is made available for the lever chain.
- a generic door lock and in particular a motor vehicle door lock is characterized within the scope of the invention in that the damping element for the lever chain is arranged on the actuating lever and / or actuated lever.
- the invention initially assumes that the lever chain acting directly or indirectly on the locking mechanism can advantageously itself be designed to be noise-dampening.
- the damping element is arranged on the actuating lever or actuated lever.
- the actuating lever denotes that lever via which a movement is initiated or passed on in the lever chain, while the actuated lever is the lever which absorbs the movement of the actuating lever and in turn passes it on.
- the damping element is designed with a cavity that can be compressed in the actuation direction during actuation contact between the two levers. That is, as soon as the two levers of the lever chain interact with one another, consequently the actuating contact mentioned between the two levers occurs, the cavity is compressed as part of the damping element, specifically in the actuating direction.
- the actuation direction is specified by the actuation lever, which works in the actuation direction on the actuated lever in order to in turn act upon it to move.
- the cavity of the damping element is generally designed in a concave arc shape with respect to the actuation direction. As soon as the actuating lever moves against the actuated lever, the cavity of the damping element is compressed with its concave arc shape in the actuating direction. This is typically achieved to the extent or until two longitudinal walls of the damping element that define the arcuate cavity and are enclosed between them bear against one another. Since the damping element itself is made of an elastically compressible material, for example plastic, a distinction can be made between a macromolecular deformation of the damping element and an intramolecular deformation through the cavity that is implemented.
- the plastic used for the damping element is advantageously a thermoplastic plastic, with polyethylene, polypropylene, polyester, polyamide, etc., for example, having proven favorable.
- Such plastics can be processed particularly easily and in particular by a plastic injection molding process.
- the damping means is usually designed as a component of a plastic casing of a metallic core of the actuating lever and / or the actuated lever.
- the interaction between the actuating lever and the actuated lever leads to the fact that the cavity as part of the damping element is initially deformed, mostly until the longitudinal walls defining the cavity rest on or against one another.
- This is accompanied by a macromolecular or macroscopic deformation of the damping means.
- the damping means in the actuating direction is still and unchanged able to absorb elastic deformation and to ensure noise damping.
- the plastic used is usually intramolecularly deformed as a material.
- individual chains of the plastic molecules are elastically deformed, which corresponds to relatively high damping rates compared to the macromolecular or macroscopic deformation when the cavity is compressed.
- the design is usually made so that the cavity forms part of a buffer pocket.
- the buffer pocket or the damping means is generally arranged on the edge of an in particular metallic contact surface.
- the procedure here is usually such that the damping element has the contact surface in question, in particular a metallic contact surface towers above, mostly against the direction of actuation.
- the contact surface can also be formed from a plastic or a multi-component material.
- the design is also made such that the damping element interacts with a damping stop, while a contact stop moves against the, in particular, metallic contact surface.
- the damping stop and the contact stop are at a distance from one another in the actuating direction.
- the design is chosen so that the damping element projects beyond the metallic contact surface by an amount which is greater than the distance between the damping stop and the contact stop.
- the damping stop and the contact stop are generally formed on the actuating lever.
- the damping stop and the contact stop are located at the end of the actuating lever and are generally equipped with the metallic contact surface.
- the actuated lever acted upon by the actuating lever also has a metallic contact surface or metallic counter-contact surface.
- this design ensures that any movement of the two levers towards each other is again dampened with the help of the damping element, so that effective rebound damping is also observed in the event of a return movement of the actuating lever after the described action on the actuated lever and an elastic coupling between the two levers .
- All of this succeeds taking into account a simple and inexpensive structure, because for this purpose only the damping means or the buffer pocket needs to be integrated into a plastic injection molding process that is usually carried out anyway when the actuating lever or the actuating lever is wrapped.
- the buffer pocket can easily be molded onto the particularly metallic core of the lever in question and designed as a component of the plastic sheathing. This is where the main advantages can be seen.
- Figs. 1 and 2 the door lock according to the invention and in particular
- FIGS. 1 and 2 shows an enlarged view from FIGS. 1 and 2 in the area of a
- a door lock which is not restrictively a motor vehicle door lock.
- This door lock has a locking mechanism (not shown in more detail) consisting essentially of a rotary latch and at least one pawl.
- a swivel chain 1, 2 works on the locking mechanism (not shown).
- the swiveling chain 1, 2 can generally be an operating lever chain for manual and / or motorized actuation of the locking mechanism.
- the fleece chain 1, 2, shown in particular in FIGS. 1 and 2 in different perspectives can also be designed as a locking lever chain and then ensures that the locking mechanism is indirectly acted upon, as has been explained in the introduction to the description.
- the basic structure of the door lock or motor vehicle door lock then also includes at least one damping element 3 for the fleece chain 1, 2.
- the damping element 3 can be arranged on the actuating lever 1 and / or on the actuated Febel 2 as part of the fleece chain 1, 2.
- the design according to the exemplary embodiment is made such that, with the aid of the actuating lever 1, the actuated lever 2 interacting therewith is acted upon, specifically pivoted.
- the actuating lever 1 can be pivoted about its axis in the indicated counterclockwise direction, for example in the representation according to FIG. 1.
- the actuating lever 1 with its end-side damping stop 1 a and its contact stop 1 b approaches an in particular metallic contact surface 4 or mating contact surface on the actuated F lever 2.
- the damping element 3 between the two flaps 1, 2 is equipped with a flea space 7 which can be compressed in the actuation direction B indicated.
- the flea space 7 is between two longitudinal walls 5, 6 of the Damping element 3 is defined.
- the cavity 7 in question can be compressed in the actuation direction B, as is indicated in particular by FIG. 3, which shows the compressed state of the cavity 7 in dash-dotted lines.
- the cavity 7 is designed in a concave arc-shaped manner with respect to the actuation direction B, that is to say it is curved inward in the actuation direction B. Also is the cavity
- damping element 3 designed as part of a buffer pocket.
- the entire damping element 3 is part of a plastic casing
- the actuating lever 1 is preferably designed as a metal lever without such a plastic casing, so that both the damping stop 1a and the contact stop 1b of the actuating lever 1 are made of metal.
- the damping element 3 is arranged on the edge of the, in particular, metallic contact surface 4.
- the damping element 3 projects beyond the, in particular, metallic contact surface 4 counter to the actuation direction B, specifically by an amount C.
- This amount C is greater than a Distance A between the damping stop 1 a and the contact stop 1 b formed on the actuating lever 1, namely in the actuating device B.
- damping element 3 has the, in particular, metallic contact surface 4 of the actuated lever 2 protrudes by the amount C, which is greater than the distance A between the damping stop 1 a and the contact stop 1 b on the actuating lever 1.
- the damping stop 1a on the actuating lever 1 first moves against the damping element 3 or its concavely curved outer longitudinal wall 5.
- the actuating lever 1 After actuation of the actuated lever 2 by the actuating lever 1, the actuating lever 1 is generally reset, for example by spring force. The same may apply to the actuated lever 2.
- the actuated lever 2 can be moved towards the actuating lever 1, which is, for example, assuming its basic position.
- Such a rebound is now additionally damped with the help of the damping element 3 between the two levers 1, 2, because during this rebound process the damping element 3 again ensures that the damping element 3 or its outer longitudinal wall 5 first rests on the damping stop 1 a of the actuating lever 1 comes and thereby this rebound movement is dampened.
- a metallic contact between the contact stop 1b on the actuating lever 1 and the metallic contact surface 4 on the actuated lever 2 is consequently not observed and avoided.
