Definitions
- the invention relates to a locking device according to the preamble of claim 1.
- the invention further relates to a method for closing the locking device.
- a lock of a locking device of the type mentioned is used for temporary closure of openings in motor vehicles or buildings by means of doors or flaps. In the closed state of such a lock, the rotary latch engages with two arms (called load arm and tentacle) around a particular bow-shaped locking bolt around.
- the locking bolt may be attached in the case of a motor vehicle to a door or flap of the motor vehicle and then the lock on the body or vice versa.
- the present invention is particularly advantageous for front hoods or front flaps, which are seen in the usual direction of travel of a motor vehicle front.
- the lock regularly includes a lock case or a lock plate and a lock cover, with the aid of the lock case is closed. Lock case and lock cover are called lock case.
- the locking mechanism, so catch and pawl are basically rotatably mounted on the lock case. For reasons of stability lock case, catch and / or Pawl advantageous metal.
- the lock lid is, inter alia, for reasons of weight advantageously made of plastic.
- a lock plate or lock case basically comprise an inlet region for the locking pin. It is an example, U-shaped bulge, which allows the locking pin to fall into the catch.
- the lock housing can be arranged on the body side or hood or door side.
- the lock housing is fixed to a motor vehicle body, for example, by screws.
- the variant mentioned in the second corresponds to the fact that the lock housing and with it the door lock is mounted inside or on a door, a hood, a flap or the like.
- a locking device particularly preferably comprises such a motor vehicle lock.
- the lock housing is regularly mounted on the body side, so it is found on an associated vehicle body.
- the locking bolt is connected to a hood, so that usually a hood lock or bonnet lock is considered. In principle, however, the procedure can also be reversed. Then the locking bolt is connected to the body or vehicle body, whereas the lock housing and with it the motor vehicle lock learns an attachment to the hood or the door generally.
- the catch of such a lock starting from an open position by pivoting a closed position, the catch is finally locked by means of the pawl.
- Such pivoting is achieved by the locking bolt (also called “lock retainer”) when it engages by closing an associated door or flap in the catch.
- a locking surface of the pawl is in the locked state of a locking surface of the rotary latch, thereby preventing that the catch can be turned back in the open position.
- the locking pin can not leave the locking mechanism in the closed position.
- Such a lock may include an electric drive to move a rusted in the pre-locking position locking in the main detent position, to finally the Lock catch in the main ratchet position.
- Such a lock is also called lock with closing aid.
- a lock with closing aid is from the DE 10 2009 026 921 A1 known.
- the DE 10 2008 005 181 A1 describes a closing aid for pulling a flap or a door of a vehicle to the vehicle body.
- the drive known from this also serves to open the door or flap.
- a combined closing and an electric opening of a tailgate lock goes out of the pamphlets DE 100 33 092 A1 , DE 10 2004 011 798 B3 such as DE 10 2004 013 671 A1 out.
- 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.
- a motor vehicle can have a generally pivotable outer handle, which can be reached from the outside, and / or a generally pivotable inner handle, which can be reached from the inside.
- a gap generally remains between the door or flap and the adjacent body.
- Such a gap should be as low as possible, especially in hoods, which are seen in the usual direction forward to avoid adverse air turbulence in the front area and concomitant air resistance during a ride.
- a possible gap-free, closed surface is also desirable for optical reasons.
- EP 1 489 252 B1 is advantageously used with closing and opening assistance devices that generally ensure that after reaching a certain prelocking the distance between the body and the hood or door to be closed is reduced (closed position). This is generally done by motor or by means of a motor drive, although in principle a mechanical closing or closing is possible and is included.
- opening devices with the aid of which the hood or motor vehicle hood or door or motor vehicle door in question is opened or displayed in relation to the motor vehicle body. In principle, such closing / opening devices can also be combined.
- the German reservation DE 10 2013 109 051 deals with minimizing such gaps in doors or flaps.
- the lock known therefrom is movable and in particular pivotally mounted. Following a locking of the locking mechanism, the lock is generally moved or pivoted by a drive in such a way that a gap between the door or flap and body is minimized.
- the drive provided for this purpose comprises an electric motor and a pivotable lever, which is called a rocker. By pivoting the lever or the rocker (hereinafter also called “rocker arm”) by the electric motor, the lock is pivoted as a whole, that the gap is minimized.
- the lock housing is held by a pawl which is rotatably mounted on the rocker.
- a locking device according to the preamble of claim 1 is in the document DE 10 2009 018 188 A1 disclosed.
- the main goal of the development is to position movable body components and in particular the vehicle hood directly above the attachments, such as a headlight, grille or body.
- the vehicle hood should be positioned on or immediately above the other attachments, so that a 0-joint is achieved.
- Such joints between attachments and / or the body and the hood on the one hand, as described, affect the aerodynamics of the motor vehicle and on the other hand crucially affect the visual and thus the overall qualitative impression of the vehicle.
- a technical problem to be solved here is that when the motor vehicle hood is closed, primarily due to the weight, the hood performs an overstroke.
- An overstroke here is the exceeding of the desired position of the closed hood, wherein the hood moves beyond the desired position, so that a 0-joint with conventional locks can not be realized. It is an object of the invention to provide a locking device and a method with which a gap of a door or flap can be minimized. To achieve the object, a closing device comprises the features of claim 1. Advantageous embodiments result from the dependent claims.
- a locking device for a door or flap has a lock with a locking mechanism of the catch and pawl for locking the catch.
- the lock comprises a closing aid so as to reduce an aforementioned gap by partially moving the locking mechanism.
- a lock with closing aid comprises a rotary latch which can be locked in both a pre-locking position and in a main locking position by at least one pawl. If the catch is locked by a pawl, so is a blocking surface of the pawl directly against a locking surface of the catch. As a result, the catch is locked reliably so that this locking mechanism will not open even with larger external load.
- the lock with a closing aid has a securing mechanism which prevents the locking mechanism from being manually moved from the pre-locking position to the main locking position.
- a stop for the striker may be provided, which prevents the striker can be moved so far by closing a door or flap in the inlet mouth of a catch that the catch can be locked in the main latching position. If the locking mechanism is locked by a pawl in the pre-locking position, this position is registered by pressing a microswitch, for example. If a microswitch registers the pre-locking position, then the microswitch is actuated. The actuation of the microswitch then sets a electric drive in progress. The drive moves the stopper out of its stop position.
- This embodiment is thus generally based on the consideration to provide a lock for minimizing the gap, which can be locked by at least one pawl in a pre-locking position and in a main latching position.
- a Zuzieh Bü to lock starting from the pre-locking position, the locking mechanism in its main locking position.
- a locking mechanism that causes the lock to be locked only by the electric drive in the main latching position.
- a gap between a flap or a door and a body can be minimized, since this can be designed so that only a very small overtravel is possible. It is thus possible in particular to reduce the gap to 4 mm and less. It is even possible to achieve a gap of 3 mm and less.
- An incidence of a latch bolt, which may be attached to a frame or door, flap or hood, into the catch causes an impact.
- a stop for the rotary latch is attached to a plate in an advantageous embodiment.
- this plate is preferably made of metal and is in particular on the body or on a door or flap of a motor vehicle attached. The plate may also be part of the bodywork of a motor vehicle.
- the load caused by said impact is introduced by the rotary latch via the stop in the plate.
- the locking bolt rotates the rotary latch in the direction of the closed position.
- the rotary latch finally hits the stopper by its rotary motion and introduces the load connected to the impact into the stop.
- the introduced into the stop load is then forwarded via the attachment of the stop on the plate in the plate. It is thus avoided damage to the drive by the impact and the associated mechanical stress. It is not necessary that the load is transmitted directly from the catch to the stop. It suffices an indirect transfer of the load into the stop inside.
- the locking device is such that the catch is latched by the pawl before the load is introduced into the stop. This ensures particularly reliable that the locking mechanism can be locked as planned.
- the catch is advantageously locked in the Vorrastpostion reasons mentioned above. The stop then prevents the catch in the main latching position can be locked.
- the lock housing and thus a locking mechanism located in the housing are pivotally mounted about an axis to a base member.
- the movement of the lock housing in the course of a closing or opening operation is effected by a pivoting movement of the lock housing about said axis.
- the rotary latch is pivoted by a drive, ie not manually, into the main latching position and latched here.
- the lock case or the lock plate of the lock housing is preferably rotatably mounted. With the lock case or the lock plate rotary latch and pawl are rotatably connected by means of axes.
- the drive By means of the drive, the lock case or the lock plate is pivoted so that a gap in a door or flap can be finally reduced.
- the presence of a lock cover is in this embodiment, although advantageous, but not mandatory.
- the lock case or the lock plate is rotatably mounted on the plate to which the stopper is attached. This contributes to a small number of components and to a small space.
- a rocker arm ie a pivotable lever, connected via a common axis with the rotatably mounted lock case.
- the term axis also means the case of a wave.
- the drive can move the free end of the rocker arm, thus also the rotatably mounted lock case for a reduction of a gap in a door or flap.
- leverage forces can be used suitably to move with suitable large force, the locking mechanism for reducing a gap of a door or flap.
- This embodiment is an independent invention regardless of the stop, with which the technical problem is solved to be able to minimize a door gap or flap gap by a simply constructed locking device.
- the lock case extends from the common axis seen in the same direction as the rocker arm. As a result, the space is advantageously kept small.
- the rocker arm extends from the common axis looking beyond the inlet region of the lock case or the lock plate addition. It are provided so favorable leverage ratios to use an electric motor with low power, which can then be advantageously built particularly small.
- a manually operable Bowden cable can act on the locking device suitable.
- a motor drive for the closing and / or opening device is provided.
- the drive only then moves the locking mechanism overall in order to minimize a door gap or flap gap when the lock is in its main latching position.
- This embodiment therefore comprises, in particular, a sensor or a microswitch, with which it can be determined when the locking mechanism is in the main latching position. If the sensor or microswitch registers that the ratchet is in the main latching position, then the sensor or microswitch will activate the drive to reduce the remaining gap in a door or flap and minimize it where possible.
- the catch has been previously moved by a closing aid from the pre-locking position to the main locking position so as to minimize a gap even by this movement alone. The ratchet then has to be moved only very slightly in order to avoid virtually any gap (zero joint). As a result, the required space can be minimized.
- the rocker arm is preferably rotatably mounted on one or more plates.
- the one or more plates consist of Stability reasons preferably made of metal.
- the one or more plates preferably have tabs with which the plates can be attached to the body of a motor vehicle or to a door or hood of a motor vehicle.
- the one or more plates then serve on the one hand the rotatable mounting of the rocker arm and on the other hand the attachment to the motor vehicle.
- the stopper is preferably rotatably mounted on the plate. This embodiment makes it possible to move the stop when needed from its stop position and in particular by an electric drive.
- the drive able to move the ratchet can also move the stop so as to minimize the number of drives required.
- this drive is also part of the closing aid.
- the drive can rotate a disk from which an eccentrically arranged bolt protrudes.
- the bolt is thus arranged away from the center of rotation or axis of rotation of the disc.
- the bolt extends into a slot of the rocker arm for moving the locking mechanism out. This means that a rotation of the disc causes a pivoting of the rocker arm and thereby also a movement of the locking mechanism.
- the bolt is alternatively or additionally used to move the stop suitable.
- it is possible in an advantageous manner to move the stop out of its stop position after said load has been introduced into it. Moving out of the stop position then allows the ratchet to move to reduce the gap.
- the rotatable components of the locking device may be biased by springs to move components into desired positions by spring force.
- a closing of the hood can be done in particular on a zero joint or a 0-gap dimension on the pawl.
- the rotary latch preferably forms the axis of rotation for the lock.
- the drive acts on the pawl and thus makes it possible to move the hood after closing the locking in a 0-gap.
- This embodiment represents an independent invention independent of the stop, but can be combined with the aforementioned features.
- the pawl then forms a rocker arm which can be driven by a drive so as to minimize a gap.
- the invention preferably relates to a lock for a hood of a motor vehicle, in particular for a hood.
- a gap or a gap of about five millimeters is provided. This gap is necessary because the hood when closing passes through an overstroke of about 5 mm. This overstroke requires that between the hood and the attachments, such as the grille or the headlight, a gap of at least 5 mm must be present.
- a door or flap such as a hood, caught in a preliminary catch and moved by means of a preferably electric motor drive from the pre-rest in the main rast ,
- a preferably electric motor drive from the pre-rest in the main rast .
- the rotary latch has a preliminary catch and a main catch, into which the hood lock comes in when closing the front flap. After reaching the main load then the catch would be pulled in an overstroke of, for example, six millimeters by means of a drive.
- a third detent position is provided, for example, on the rotary latch.
- the entire lock unit is moved in a 0-joint position.
- the lock will be accommodated mounted in an eccentric drive, so that the castle would close in an excessive position.
- the entire lock is then in particular driven by an electric motor pivoted by means of the drive, so that the door or flap in turn can be moved in a 0-joint position.
- the invention is in one embodiment, the technical problem of further developing such a locking device so that with simple means the smallest possible gap between the body and door or hood can be provided.
- a generic locking device in the invention is characterized in that the closing and / or opening device on the outside on Lock housing attacks to its adjustment relative to a stationary base element in the course of a closing / opening process.
- the stationary base element is a component of this motor vehicle body.
- the motor vehicle door lock or hood lock according to the invention is located in the region of an upper front carrier on the front of the motor vehicle body, which is typically arranged or extends horizontally.
- the design is advantageously made such that the lock housing is pivotally connected to the base element in question about an axis or axis of rotation. That is, the adjustment of the lock housing in the course of the closing / opening operation corresponds to a pivoting movement of the lock housing about the axis in question or axis of rotation.
- the axis or axis of rotation is generally defined such that in the example, the upper front support of the vehicle body is equipped with a corresponding pin or pin on which the lock housing is rotatably mounted.
- the lock case is generally rotatably mounted on the bolt in question.
- the lock cover is connected to the lock case and is taken along during a pivoting movement of the lock case as it were.
- the described closing / opening process can basically be carried out mechanically.
- this may include a Work Bowden cable on the closing and / or opening device that can be operated manually.
- a motor drive for the closing and / or opening device is provided. It has been proven that the motor drive works eccentrically on the closing / opening device. Moreover, it is advantageous if the motor drive only then acts on the closing and or opening device when the door lock is in its main latching position.
- the closing and / or opening device essentially consists of a rocker and a pawl acting on the lock housing.
- the rocker With the help of the rocker relatively large torques can be exerted on the lock housing, even when working with a small-build motor drive, which applies a rather small force.
- the rocker is usually rotatably connected to the base member. It has proven useful if the rocker and the lock housing are connected coaxially rotatable to the base element. In this case, therefore, the bolt acts on the upper front support of the vehicle body advantageous as a common axis of rotation for one hand, the lock housing and on the other hand, the rocker. In addition, this provides a particularly compact and less bulky construction available.
- the pawl in turn is generally rotatably mounted on the sling.
- the latch may be biased by means of a spring.
- the rocker For actuating the rocker and for pivoting about the common axis of rotation with the lock housing, the rocker is largely equipped with a slot for engagement of an actuating pin.
- the actuating pin is in turn advantageously applied by means of the motor drive.
- the design is regularly made so that the actuating pin is arranged on a driven pulley.
- the driven pulley can be rotated by means of a motor or electric motor.
- the electric motor has on its output shaft via a worm, which engages in an outer edge side toothing of the driven pulley in order to pivot it counterclockwise or clockwise about an associated axis. This results in movements of the actuating pin on a circular arc, and indeed within the elongated hole of the rocker.
- a motor drive is on the DE 299 15 905 U1 directed.
- the actuating pin performs inside the long hole of the rocker initiated by the motor drive circular arc movements.
- the rocker and with it the lock housing can be pivoted about the common axis of rotation relative to the base member. Because a pivoting movement of the rocker has the consequence that the lock housing is taken over the pawl during the rotational movement of the rocker.
- a locking device is provided, which is particularly suitable for providing small gap widths between the associated door or hood and body, which can be set to 0 mm 20 or almost 0 mm.
- the invention achieves the core in that by means of the closing and / or opening device, the entire lock housing with respect to the base member or an upper and usually arranged horizontally Front carrier of the vehicle body is pivoted. That is, the closing and / or opening device engages in this embodiment explicitly not on a mounted in the associated lock case lock.
- the locking mechanism when closing the door or hood is first transferred to a main locking position or main detent position.
- This position starts the closing or closing process according to the invention.
- the entire lock housing is then pivoted with the locking mechanism located in the main lock and thus captured here locking bolt about the axis of rotation relative to the vehicle body.
- This can be done very sensitively and compared to an attacking, for example, on the catch closing movement with much larger lever arms and correspondingly higher torques.
- virtually any gap widths between the door or hood and the motor vehicle body can be realized, which extend down to 0 mm or almost 0 mm. All of this succeeds considering a simple and functional design.
- the main advantages of this embodiment are the main advantages of this embodiment.
- an electrically operated hood lock (E-lock) is used and combined with a closing aid.
- the hood seals are regularly opened by the fact that in a first step, that is, a first pulling the Hood opening lever the lock, or the catch hook of the locking mechanism reaches a pre-locking position in which the hood is already open by means of spring force, but the hood can not be opened. Only after a second second pull on the hood opening lever of the fishing hook, or the locking mechanism release the lock strap of the hood, so that the hood can be opened manually.
- an electrically operated lock (with closing aid) is combined with an electrically operated adjusting device.
- the hood lock as described in the German Pre-Declarations 10 2013 109 051 and 10 2013 222 053, electrically traversed, but then release not manually but electrically actuated the locking mechanism.
- An advantageous two-stage opening process will thus be fulfilled.
- a two-stage locking mechanism and after reaching a pre-restraint when closing the hood, the locking mechanism in a main ratchet pulled by an electric motor.
- the FIG. 1 illustrates the structure of a closure device for a door or flap of a motor vehicle.
- the locking device has a lock with a locking mechanism of rotary latch 1 and pawl 2.
- the catch 1 can in a closed position with the pawl 2 as in the FIG. 1 be shown locked.
- the pawl 2 is rotatably mounted on a lock plate 3 by an axis 5.
- the rotary latch 2 is rotatably mounted on the lock plate 3 by means of its axis 4.
- a lock case may be present. In the present case, however, for reasons of space, a lock plate 3 is to be preferred, which therefore, in contrast to a lock case, does not include any side walls.
- the lock plate 3 or the lock case are preferably made of metal.
- Pawl 2 and / or rotary latch 1 are preferably also entirely or at least partially made of metal.
- the drive 6 has for this purpose in particular via an electric motor 7 and connected to the shaft of the motor screw 8.

Description
Die Erfindung betrifft eine Schließvorrichtung gemäß dem Oberbegriff des Anspruchs 1. Die Erfindung betrifft ferner ein Verfahren für ein Schließen der Schließvorrichtung.
Ein Schloss einer Schließvorrichtung der eingangs genannten Art dient zum zeitweisen Verschließen von Öffnungen in Kraftfahrzeugen oder Gebäuden mit Hilfe von Türen oder Klappen. Im geschlossenen Zustand eines solchen Schlosses greift die Drehfalle mit zwei Armen (Lastarm sowie Fangarm genannt) um einen insbesondere bügelförmig ausgeführten Schließbolzen herum. Der Schließbolzen kann im Fall eines Kraftfahrzeugs an einer Tür oder Klappe des Kraftfahrzeugs befestigt sein und dann das Schloss an der Karosserie oder umgekehrt. Im Fall eines Kraftfahrzeugs gibt es insbesondere Seitentürschlösser, Heckklappenschlösser und Haubenschlösser bzw. Motorhaubenschlösser. Die vorliegende Erfindung ist besonders vorteilhaft für Fronthauben bzw. Frontklappen, die sich in üblicher Fahrtrichtung eines Kraftfahrzeugs gesehen vorne befinden.
Das Schloss umfasst regelmäßig einen Schlosskasten oder eine Schlossplatte sowie einen Schlossdeckel, mit dessen Hilfe der Schlosskasten verschlossen wird. Schlosskasten und Schlossdeckel werden Schlossgehäuse genannt. Das Gesperre, also Drehfalle und Sperrklinke, sind grundsätzlich am Schlosskasten drehbar angebracht. Aus Stabilitätsgründen bestehen Schlosskasten, Drehfalle und/oder Sperrklinke vorteilhaft aus Metall. Der Schlossdeckel besteht u. a. aus Gewichtsgründen vorteilhaft aus Kunststoff. Eine Schlossplatte oder Schlosskasten umfassen grundsätzlich einen Einlaufbereich für den Schließbolzen. Es handelt sich dabei um eine beispielsweise U-förmige Ausbuchtung, die es dem Schließbolzen ermöglicht, in die Drehfalle einzufallen.The invention relates to a locking device according to the preamble of
A lock of a locking device of the type mentioned is used for temporary closure of openings in motor vehicles or buildings by means of doors or flaps. In the closed state of such a lock, the rotary latch engages with two arms (called load arm and tentacle) around a particular bow-shaped locking bolt around. The locking bolt may be attached in the case of a motor vehicle to a door or flap of the motor vehicle and then the lock on the body or vice versa. In the case of a motor vehicle, there are in particular side door locks, tailgate locks and hood locks or bonnet locks. The present invention is particularly advantageous for front hoods or front flaps, which are seen in the usual direction of travel of a motor vehicle front.
The lock regularly includes a lock case or a lock plate and a lock cover, with the aid of the lock case is closed. Lock case and lock cover are called lock case. The locking mechanism, so catch and pawl are basically rotatably mounted on the lock case. For reasons of stability lock case, catch and / or Pawl advantageous metal. The lock lid is, inter alia, for reasons of weight advantageously made of plastic. A lock plate or lock case basically comprise an inlet region for the locking pin. It is an example, U-shaped bulge, which allows the locking pin to fall into the catch.
Wie üblich, kann das Schlossgehäuse karosserieseitig oder hauben- bzw. türseitig angeordnet werden. Im erstgenannten Fall wird das Schlossgehäuse an einer Kraftfahrzeugkarosserie beispielsweise durch Schrauben festgelegt. Die an zweiter Stelle genannte Variante korrespondiert dazu, dass das Schlossgehäuse und mit ihm das Türschloss im Innern oder an einer Tür, einer Haube, einer Klappe oder dergleichen angebracht wird.As usual, the lock housing can be arranged on the body side or hood or door side. In the former case, the lock housing is fixed to a motor vehicle body, for example, by screws. The variant mentioned in the second corresponds to the fact that the lock housing and with it the door lock is mounted inside or on a door, a hood, a flap or the like.
Folgerichtig werden in der Praxis beispielsweise Seitentürschlösser, Heckklappenschlösser und Haubenschlösser bzw. Motorhaubenschlösser unterschieden. Diese fallen sämtlich unter den Begriff Kraftfahrzeugschloss. Eine Schließvorrichtung umfasst besonders bevorzugt ein solches Kraftfahrzeugschloss.Consequently, in practice, for example, side door locks, tailgate locks and hood locks or bonnet locks are distinguished. These fall all under the term motor vehicle lock. A locking device particularly preferably comprises such a motor vehicle lock.
Im Rahmen der Erfindung ist das Schlossgehäuse regelmäßig karosserieseitig angebracht, findet sich also an einer zugehörigen Kraftfahrzeugkarosserie. Demgegenüber ist der Schließbolzen an eine Haube angeschlossen, so dass meistens ein Haubenschloss bzw. Motorhaubenschloss betrachtet wird. Grundsätzlich kann aber auch umgekehrt vorgegangen werden. Dann ist der Schließbolzen an die Karosserie bzw. Kraftfahrzeugkarosserie angeschlossen, wohingegen das Schlossgehäuse und mit ihm das Kraftfahrzeugschloss eine Anbringung an der Haube oder allgemein türseitig erfährt.In the context of the invention, the lock housing is regularly mounted on the body side, so it is found on an associated vehicle body. In contrast, the locking bolt is connected to a hood, so that usually a hood lock or bonnet lock is considered. In principle, however, the procedure can also be reversed. Then the locking bolt is connected to the body or vehicle body, whereas the lock housing and with it the motor vehicle lock learns an attachment to the hood or the door generally.
Erreicht die Drehfalle eines solchen Schlosses ausgehend von einer geöffneten Stellung durch Verschwenken eine Schließstellung, so wird die Drehfalle schließlich mittels der Sperrklinke verrastet. Ein solches Verschwenken wird durch den Schließbolzen (auch "Schlosshalter" genannt) erreicht, wenn dieser durch ein Schließen einer zugehörigen Tür oder Klappe in die Drehfalle einfällt. Eine Sperrfläche der Sperrklinke liegt im verrasteten Zustand an einer Sperrfläche der Drehfalle an, wodurch verhindert wird, dass die Drehfalle in Richtung geöffnete Stellung zurückgedreht werden kann. Der Schließbolzen kann das Gesperre in der Schließstellung nicht mehr verlassen.Reached the catch of such a lock, starting from an open position by pivoting a closed position, the catch is finally locked by means of the pawl. Such pivoting is achieved by the locking bolt (also called "lock retainer") when it engages by closing an associated door or flap in the catch. A locking surface of the pawl is in the locked state of a locking surface of the rotary latch, thereby preventing that the catch can be turned back in the open position. The locking pin can not leave the locking mechanism in the closed position.
Für ein Öffnen ist es erforderlich, die Sperrklinke aus ihrer Raststellung heraus zu bewegen. Ist die Sperrklinke aus ihrer Raststellung heraus bewegt worden, so dreht sich die Drehfalle in Richtung geöffnete Stellung. In der geöffneten Stellung der Drehfalle und damit in der geöffneten Stellung des Gesperres kann der Schließbolzen das Schloss verlassen. Die Tür oder Klappe kann so wieder geöffnet werden.For opening, it is necessary to move the pawl out of its detent position. If the pawl has been moved out of its detent position, the rotary latch rotates in the direction of the open position. In the open position of the catch and thus in the open position of the locking mechanism, the locking bolt can leave the lock. The door or flap can be opened again.
Es gibt Schlösser mit zwei verschiedenen Raststellungen der Drehfalle. Die Drehfalle kann dann zunächst in der sogenannten Vorrastposition verrastet werden und durch ein Weiterdrehen in Schließrichtung schließlich in der sogenannten Hauptrastposition. In der Vorrastposition kann zwar ein Schließbolzen das Gesperre nicht mehr verlassen. Eine entsprechende Tür oder Klappe ist aber noch nicht vollständig geschlossen. Eine solche Tür oder Klappe ist erst dann vollständig verschlossen, wenn die Drehfalle bis zur Hauptrastposition gedreht und hier verrastet wird. Für ein Verrasten in der Vorrastposition kann eine zweite Sperrklinke vorgesehen sein. Es ist aber auch möglich, die Drehfalle mit nur einer Sperrklinke sowohl in der Vorrastposition als auch in der Hauptrastposition zu verrasten. Ein solches Schloss kann einen elektrischen Antrieb umfassen, um ein in der Vorrastposition verrostetes Gesperre in die Hauptrastposition zu bewegen, um schließlich das Gesperre in der Hauptrastposition zu verrasten. Ein solches Schloss wird auch Schloss mit Zuziehhilfe genannt. Ein Schloss mit Zuziehhilfe ist aus der
Die
Um ein Schloss öffnen zu können, gibt es eine Betätigungseinrichtung. Wird die Betätigungseinrichtung betätigt, so öffnet sich das Gesperre. Ein Griff einer Tür oder einer Klappe kann Teil der Betätigungseinrichtung sein. Dieser Griff wird in der Regel über ein Gestänge oder einen Bowdenzug mit einem Betätigungshebel des Schlosses verbunden. Wird der Griff betätigt, so wird mittels des Gestänges oder des Bowdenzugs der Betätigungshebel des Schlosses so verschwenkt, dass sich das Schloss öffnet. Ein Kraftfahrzeug kann einen in der Regel schwenkbaren Außengriff, der von außen erreichbar ist, und/oder einen in der Regel schwenkbaren Innengriff, der von innen erreichbar ist, aufweisen.To open a lock, there is an actuator. When the actuating device is actuated, the locking mechanism opens. 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. A motor vehicle can have a generally pivotable outer handle, which can be reached from the outside, and / or a generally pivotable inner handle, which can be reached from the inside.
Wird ein Gesperre eines Kraftfahrzeugs durch Schließen einer Tür oder Klappe verrastet, so verbleibt grundsätzlich zwischen der Tür bzw. Klappe und der angrenzenden Karosserie ein Spalt. Ein solcher Spalt soll vor allem bei Hauben, die sich in üblicher Fahrtrichtung gesehen vorne befinden, so gering wie möglich sein, um nachteilhafte Luftverwirbelungen im Frontbereich und damit einhergehende Luftwiderstände während einer Fahrt zu vermeiden. Eine möglichst spaltfreie, geschlossene Oberfläche ist aber auch aus optischen Gründen erwünscht.If a locking mechanism of a motor vehicle is locked by closing a door or flap, a gap generally remains between the door or flap and the adjacent body. Such a gap should be as low as possible, especially in hoods, which are seen in the usual direction forward to avoid adverse air turbulence in the front area and concomitant air resistance during a ride. A possible gap-free, closed surface is also desirable for optical reasons.
In der Praxis und im Stand der Technik nach der
Im Allgemeinen wird jedoch meistens nur mit einer Schließhilfe bzw. Schließeinrichtung gearbeitet, die eine beispielsweise in Vorraststellung des Gesperres befindliche Kraftfahrzeugtür in die Hauptraststellung motorisch zuzieht. Dazu wird im gattungsbildenden Stand der Technik nach der
In neuerer Zeit und insbesondere bei sogenannten Haubenschlössern, also Kraftfahrzeugtürschlössern an einer Kraftfahrzeughaube oder im Bereich der Kraftfahrzeughaube, ergeben sich nun Anforderungen dahingehend, einen Spalt zwischen der Kraftfahrzeugtür bzw. der Kraftfahrzeughaube und der Kraftfahrzeugkarosserie so gering wie möglich einzustellen und möglichst bis auf 0 mm oder nahezu 0 mm zu verringern. Diese Anforderung erklärt sich nicht nur aufgrund ästhetischer Überlegungen, die eine möglichst glattflächige und geschlossene Oberfläche für ein modernes Kraftfahrzeug fordern. Sondern die Größe des Spaltes hat insbesondere in diesem Bereich unmittelbare Auswirkungen auf Luftverwirbelungen im Frontbereich, die je nach ihrer Entstehung und Ausprägung den Luftwiderstand negativ beeinflussen können. An dieser Stelle fehlen bisher überzeugende Lösungen. Hier setzt die Erfindung in einer vorteilhaften Ausgestaltung ein.In recent times, and in particular in so-called hood locks, so motor vehicle door locks on a motor vehicle hood or in the field of motor vehicle hood, there are now requirements to set a gap between the motor vehicle door or the motor vehicle body and the vehicle body as low as possible and possibly up to 0 mm or almost 0 mm too reduce. This requirement is explained not only due to aesthetic considerations that require a smooth surface as possible and closed surface for a modern motor vehicle. But the size of the gap has, especially in this area, immediate effects on air turbulences in the front area, which can negatively influence the air resistance depending on their formation and expression. At this point, convincing solutions are missing so far. This is where the invention in an advantageous embodiment.

Soweit nachfolgend nichts anderes angegeben, kann der Gegenstand der Erfindung die vorgenannten Merkmale einzeln oder in beliebiger Kombination aufweisen.Unless otherwise stated below, the subject matter of the invention may have the aforementioned features individually or in any combination.
Eine Schließvorrichtung gemäß dem Oberbegriff des Anspruchs 1 ist im Dokument
Ziel der Entwicklung ist es vor allem, bewegliche Karosseriebauteile und insbesondere die Fahrzeughaube unmittelbar über den Anbauteilen, wie beispielsweise einem Scheinwerfer, einem Kühlergrill oder der Karosserie zu positionieren. Hierbei soll die Fahrzeughaube auf oder unmittelbar über den weiteren Anbauteilen positioniert werden, so dass eine 0-Fuge erzielt wird. Derartige Fugen zwischen Anbauteilen und/oder der Karosserie und der Haube können einerseits wie beschrieben die Aerodynamik des Kraftfahrzeuges beeinflussen und andererseits entscheidend den optischen und somit den qualitativen Gesamteindruck des Fahrzeuges beeinflussen.
Eine zu lösende technische Aufgabe ist es hierbei, dass bei einem Schließen der Kraftfahrzeughaube, vornehmlich gewichtsbedingt, die Haube einen Überhub vollzieht. Ein Überhub ist hierbei das Überschreiten der Sollposition der geschlossenen Haube, wobei die Haube sich über die Sollposition hinaus bewegt, so dass eine 0-Fuge mit herkömmlichen Schlössern nicht zu realisieren ist. Es ist Aufgabe der Erfindung, eine Schließvorrichtung sowie ein Verfahren bereitzustellen, mit der ein Spalt einer Tür oder Klappe minimiert werden kann.
Zur Lösung der Aufgabe umfasst eine Schließvorrichtung die Merkmale des Anspruchs 1. Vorteilhafte Ausgestaltungen ergeben sich aus den abhängigen Ansprüchen.The main goal of the development is to position movable body components and in particular the vehicle hood directly above the attachments, such as a headlight, grille or body. Here, the vehicle hood should be positioned on or immediately above the other attachments, so that a 0-joint is achieved. Such joints between attachments and / or the body and the hood on the one hand, as described, affect the aerodynamics of the motor vehicle and on the other hand crucially affect the visual and thus the overall qualitative impression of the vehicle.
A technical problem to be solved here is that when the motor vehicle hood is closed, primarily due to the weight, the hood performs an overstroke. An overstroke here is the exceeding of the desired position of the closed hood, wherein the hood moves beyond the desired position, so that a 0-joint with conventional locks can not be realized. It is an object of the invention to provide a locking device and a method with which a gap of a door or flap can be minimized.
To achieve the object, a closing device comprises the features of
Eine Schließvorrichtung für eine Tür oder Klappe weist ein Schloss mit einem Gesperre aus Drehfalle und Sperrklinke für ein Verrasten der Drehfalle auf. Es gibt einen Antrieb, mit dem das Gesperre ganz oder teilweise so bewegt werden kann, dass ein Türspalt oder Klappenspalt verkleinert werden kann. Wird also eine Tür oder Klappe geschlossen, so verbleibt zunächst ein Spalt zwischen Tür und Türrahmen bzw. zwischen einem Rahmen und der zugehörigen Klappe. Durch den Antrieb kann das Gesperre oder Teile des Gesperres so bewegt werden, dass sich dieser Spalt verringert.A locking device for a door or flap has a lock with a locking mechanism of the catch and pawl for locking the catch. There is a drive with which the ratchet can be moved in whole or in part so that a door gap or flap gap can be reduced. Thus, if a door or flap is closed, initially there remains a gap between the door and the door frame or between a frame and the associated flap. By the drive, the locking mechanism or parts of the locking mechanism can be moved so that this gap is reduced.
Das Schloss umfasst eine Zuziehhilfe, um so durch teilweises Bewegen des Gesperres einen vorgenannten Spalt zu verkleinern. Ein solches Schloss mit Zuziehhilfe umfasst eine Drehfalle, die sowohl in einer Vorrastposition als auch in einer Hauptrastposition durch zumindest eine Sperrklinke verrastet werden kann. Wird die Drehfalle durch eine Sperrklinke verrastet, so liegt eine Sperrfläche der Sperrklinke unmittelbar an einer Sperrfläche der Drehfalle an. Hierdurch wird die Drehfalle so zuverlässig verrastet, dass dieses Gesperre sich auch bei größere äußere Last nicht öffnen wird.The lock comprises a closing aid so as to reduce an aforementioned gap by partially moving the locking mechanism. Such a lock with closing aid comprises a rotary latch which can be locked in both a pre-locking position and in a main locking position by at least one pawl. If the catch is locked by a pawl, so is a blocking surface of the pawl directly against a locking surface of the catch. As a result, the catch is locked reliably so that this locking mechanism will not open even with larger external load.
Erfindungsgemäß weist das Schloss mit Zuziehhilfe einen Sicherungsmechanismus auf, der verhindert, dass das Gesperre manuell von der Vorrastposition in die Hauptrastposition bewegt werden kann. So kann ein Anschlag für den Schließbügel vorgesehen sein, der verhindert, dass der Schließbügel derart weit durch das Schließen einer Tür oder Klappe in das Einlaufmaul einer Drehfalle hineinbewegt werden kann, dass die Drehfalle in der Hauptrastposition verrastet werden kann. Wird das Gesperre durch eine Sperrklinke in der Vorrastposition verrastet, so wird diese Position zum Beispiel durch einen Mikroschalter durch Betätigen registriert. Registriert ein Mikroschalter die Vorrastposition, so wird also der Mikroschalter betätigt. Die Betätigung des Mikroschalters setzt dann einen elektrischen Antrieb in Gang. Durch den Antrieb wird der Anschlag aus seiner Anschlagsposition bewegt. Im Anschluss daran wird die Drehfalle in Richtung Hauptrastposition durch einen elektrischen Antrieb gedreht, bis die Drehfalle in der Hauptrastposition verrastet wird.
Diese Ausgestaltung beruht also allgemein auf der Überlegung, zur Spaltminimierung ein Schloss bereitzustellen, welches durch wenigstens eine Sperrklinke in einer Vorrastposition und in einer Hauptrastposition verrastet werden kann. Es gibt eine Zuziehhilfe, um ausgehend von der Vorrastposition das Gesperre in seiner Hauptrastposition zu Verrasten. Darüber hinaus gibt es einen Sicherungsmechanismus, durch den bewirkt wird, dass das Schloss nur mithilfe des elektrischen Antriebs in der Hauptrastposition verrastet werden kann.According to the invention, the lock with a closing aid has a securing mechanism which prevents the locking mechanism from being manually moved from the pre-locking position to the main locking position. Thus, a stop for the striker may be provided, which prevents the striker can be moved so far by closing a door or flap in the inlet mouth of a catch that the catch can be locked in the main latching position. If the locking mechanism is locked by a pawl in the pre-locking position, this position is registered by pressing a microswitch, for example. If a microswitch registers the pre-locking position, then the microswitch is actuated. The actuation of the microswitch then sets a electric drive in progress. The drive moves the stopper out of its stop position. Thereafter, the catch is rotated in the direction of the main latching position by an electric drive until the catch is locked in the main latching position.
This embodiment is thus generally based on the consideration to provide a lock for minimizing the gap, which can be locked by at least one pawl in a pre-locking position and in a main latching position. There is a Zuziehhilfe to lock starting from the pre-locking position, the locking mechanism in its main locking position. In addition, there is a locking mechanism that causes the lock to be locked only by the electric drive in the main latching position.
Durch diese Merkmale wird sichergestellt, dass die Drehfalle nicht bis zur Hauptrastposition mit übermäßig hoher Geschwindigkeit gedreht werden kann. Es wird so das Erreichen eines übermäßig großen Überhubs vermieden. Im Vergleich zu üblichen Schlössern mit Vorrastposition und Hauptrastposition kann daher ein Spalt zwischen einer Klappe bzw. einer Tür und einer Karosserie minimiert werden, da dieser so ausgelegt werden kann, dass ein nur sehr kleiner Überhub möglich ist. Es ist so insbesondere möglich, das Spaltmaß auf 4 mm und weniger zu reduzieren. Es ist sogar möglich, ein Spaltmaß von 3 mm und weniger zu erreichen.
Ein Einfallen eines Schließbolzens, der an einem Rahmen oder an der Tür, Klappe bzw. Haube angebracht sein kann, in die Drehfalle bewirkt einen Aufprall. Um Beschädigungen aufgrund eines solchen Einfallens zu vermeiden, ist in einer vorteilhaften Ausführungsform ein Anschlag für die Drehfalle an einer Platte angebracht. Aus Stabilitätsgründen besteht diese Platte vorzugsweise aus Metall und ist insbesondere an der Karosserie oder an einer Tür oder Klappe eines Kraftfahrzeugs befestigt. Die Platte kann auch Teil der Karosserie eines Kraftfahrzeugs sein.These features ensure that the catch can not be rotated up to the main detent position at excessively high speed. This avoids the achievement of an excessively large overstroke. Compared to conventional locks with pre-locking position and main detent position, therefore, a gap between a flap or a door and a body can be minimized, since this can be designed so that only a very small overtravel is possible. It is thus possible in particular to reduce the gap to 4 mm and less. It is even possible to achieve a gap of 3 mm and less.
An incidence of a latch bolt, which may be attached to a frame or door, flap or hood, into the catch causes an impact. In order to avoid damage due to such an incidence, a stop for the rotary latch is attached to a plate in an advantageous embodiment. For reasons of stability, this plate is preferably made of metal and is in particular on the body or on a door or flap of a motor vehicle attached. The plate may also be part of the bodywork of a motor vehicle.
Die durch den genannten Aufprall bewirkte Last wird von der Drehfalle über den Anschlag in die Platte eingeleitet. Mit anderen Worten: Fällt ein Schließbolzen in die Drehfalle ein, so dreht der Schließbolzen die Drehfalle in Richtung Schließstellung. Die Drehfalle trifft durch ihre Drehbewegung schließlich auf den Anschlag auf und leitet die mit dem Aufprall verbundene Last in den Anschlag ein. Die in den Anschlag eingeleitete Last wird anschließend über die Anbringung des Anschlags an der Platte in die Platte weitergeleitet. Es wird so eine Beschädigung des Antriebs durch den Aufprall und die damit verbundene mechanische Belastung vermieden. Es ist nicht erforderlich, dass die Last unmittelbar von der Drehfalle auf den Anschlag übertragen wird. Es genügt eine mittelbare Übertragung der Last in den Anschlag hinein.The load caused by said impact is introduced by the rotary latch via the stop in the plate. In other words: If a locking pin falls into the rotary latch, the locking bolt rotates the rotary latch in the direction of the closed position. The rotary latch finally hits the stopper by its rotary motion and introduces the load connected to the impact into the stop. The introduced into the stop load is then forwarded via the attachment of the stop on the plate in the plate. It is thus avoided damage to the drive by the impact and the associated mechanical stress. It is not necessary that the load is transmitted directly from the catch to the stop. It suffices an indirect transfer of the load into the stop inside.
Vorteilhaft ist die Schließvorrichtung so beschaffen ist, dass die Drehfalle durch die Sperrklinke verrastet wird, bevor die Last in den Anschlag eingeleitet wird. Hierdurch wird besonders zuverlässig sichergestellt, dass das Gesperre planmäßig verrastet werden kann. Die Drehfalle wird aus vorgenannten Gründen vorteilhaft in der Vorrastpostion verrastet. Der Anschlag verhindert dann, dass die Drehfalle in der Hauptrastposition verrastet werden kann.Advantageously, the locking device is such that the catch is latched by the pawl before the load is introduced into the stop. This ensures particularly reliable that the locking mechanism can be locked as planned. The catch is advantageously locked in the Vorrastpostion reasons mentioned above. The stop then prevents the catch in the main latching position can be locked.
In einer Ausführungsform sind das Schlossgehäuse und damit ein im Gehäuse befindliches Gesperre um eine Achse schwenkbar an einem Basiselement befestigt. Das Bewegen des Schlossgehäuses im Zuge eines Schließ- oder Öffnungsvorganges wird durch eine Schwenkbewegung des Schlossgehäuses um die genannte Achse bewirkt. Alternativ oder ergänzend wird im Anschluss an das Erreichen der Vorrastposition die Drehfalle durch einen Antrieb, also nicht manuell, in die Hauptrastposition verschwenkt und hier verrastet. Vorzugsweise wird aus Stabilitätsgründen der Schlosskasten oder die Schlossplatte des Schlossgehäuses drehbar gelagert. Mit dem Schlosskasten bzw. der Schlossplatte sind Drehfalle und Sperrklinke mithilfe von Achsen drehbar verbunden. Mithilfe des Antriebs wird der Schlosskasten bzw. die Schlossplatte so verschwenkt, dass dadurch ein Spalt bei einer Tür oder Klappe schließlich verringert werden kann. Das Vorhandensein eines Schlossdeckels ist bei dieser Ausführungsform zwar vorteilhaft, aber nicht zwingend erforderlich.In one embodiment, the lock housing and thus a locking mechanism located in the housing are pivotally mounted about an axis to a base member. The movement of the lock housing in the course of a closing or opening operation is effected by a pivoting movement of the lock housing about said axis. Alternatively or additionally, following the reaching of the pre-locking position, the rotary latch is pivoted by a drive, ie not manually, into the main latching position and latched here. For reasons of stability, the lock case or the lock plate of the lock housing is preferably rotatably mounted. With the lock case or the lock plate rotary latch and pawl are rotatably connected by means of axes. By means of the drive, the lock case or the lock plate is pivoted so that a gap in a door or flap can be finally reduced. The presence of a lock cover is in this embodiment, although advantageous, but not mandatory.
Vorzugsweise ist der Schlosskasten oder die Schlossplatte an der Platte drehbar angebracht, an der der Anschlag angebracht ist. Dies trägt zu einer geringen Zahl an Bauteilen und zu einem kleinen Bauraum bei.Preferably, the lock case or the lock plate is rotatably mounted on the plate to which the stopper is attached. This contributes to a small number of components and to a small space.
In einer Ausgestaltung der Erfindung ist ein Schwinghebel (Schwinge), also ein schwenkbarer Hebel, über eine gemeinsame Achse mit dem drehbar gelagerten Schlosskasten verbunden. Der Begriff Achse meint auch den Fall einer Welle. Der Antrieb kann das freie Ende des Schwinghebels bewegen, um damit auch den drehbar gelagerten Schlosskasten für eine Verringerung eines Spalts bei einer Tür oder Klappe. Durch diese Ausgestaltung können Hebelkräfte geeignet genutzt werden, um mit geeignet großer Kraft das Gesperre für eine Verringerung eines Spalts einer Tür oder Klappe bewegen zu können. Diese Ausgestaltung stellt eine eigenständige Erfindung unabhängig von dem Anschlag dar, mit der das technische Problem gelöst wird, einen Türspalt oder Klappenspalt durch eine einfach konstruierte Schließvorrichtung minimieren zu können.In one embodiment of the invention, a rocker arm (rocker), ie a pivotable lever, connected via a common axis with the rotatably mounted lock case. The term axis also means the case of a wave. The drive can move the free end of the rocker arm, thus also the rotatably mounted lock case for a reduction of a gap in a door or flap. By this configuration, leverage forces can be used suitably to move with suitable large force, the locking mechanism for reducing a gap of a door or flap. This embodiment is an independent invention regardless of the stop, with which the technical problem is solved to be able to minimize a door gap or flap gap by a simply constructed locking device.
In einer Ausgestaltung der Erfindung erstreckt sich der Schlosskasten von der gemeinsamen Achse aus gesehen in gleicher Richtung wie der Schwinghebel. Hierdurch wird vorteilhaft der Bauraum klein gehalten.In one embodiment of the invention, the lock case extends from the common axis seen in the same direction as the rocker arm. As a result, the space is advantageously kept small.
In einer Ausgestaltung der Erfindung reicht der Schwinghebel von der gemeinsamen Achse ausgesehen über den Einlaufbereich des Schlosskastens oder der Schlossplatte hinaus. Es werden so günstige Hebelverhältnisse bereitgestellt, um einen Elektromotor mit geringer Leistung einsetzen zu können, der dann vorteilhaft besonders klein gebaut sein kann.In one embodiment of the invention, the rocker arm extends from the common axis looking beyond the inlet region of the lock case or the lock plate addition. It are provided so favorable leverage ratios to use an electric motor with low power, which can then be advantageously built particularly small.
Der beschriebene Schließ-/Öffnungsvorgang kann zwar in einer Ausgestaltung auch manuell bewirkt werden. So kann ein manuell betätigbarer Bowdenzug auf die Schließvorrichtung geeignet einwirken. Im Regelfall ist jedoch ein motorischer Antrieb für die Schließ- und/oder Öffnungseinrichtung vorgesehen.Although the described closing / opening process can also be effected manually in one embodiment. Thus, a manually operable Bowden cable can act on the locking device suitable. As a rule, however, a motor drive for the closing and / or opening device is provided.
Vorteilhaft bewegt der Antrieb erst dann insgesamt das Gesperre zwecks Minimierung eines Türspalts oder Klappenspalts, wenn sich das Schloss in seiner Hauptraststellung befindet. Diese Ausführungsform umfasst daher insbesondere einen Sensor oder einen Mikroschalter, mit dem festgestellt werden kann, wenn sich das Gesperre in der Hauptrastposition befindet. Registriert der Sensor oder Mikroschalter, dass sich das Gesperre in der Hauptrastposition befindet, so aktiviert der Sensor oder Mikroschalter dann den Antrieb, um den noch vorhandenen Spalt bei einer Tür oder Klappe zu verkleinern und so nach Möglichkeit zu minimieren. Auch bei dieser Ausführungsform ist vorteilhaft zuvor die Drehfalle durch eine Zuziehhilfe von der Vorrastposition in die Hauptrastposition bewegt worden, um so bereits allein durch diese Bewegung einen Spalt zu minimieren. Das Gesperre muss dann insgesamt nur noch sehr geringfügig weiter bewegt werden, um praktisch jeden Spalt zu vermeiden (Nullfuge). Hierdurch kann der erforderliche Bauraum minimiert werden.Advantageously, the drive only then moves the locking mechanism overall in order to minimize a door gap or flap gap when the lock is in its main latching position. This embodiment therefore comprises, in particular, a sensor or a microswitch, with which it can be determined when the locking mechanism is in the main latching position. If the sensor or microswitch registers that the ratchet is in the main latching position, then the sensor or microswitch will activate the drive to reduce the remaining gap in a door or flap and minimize it where possible. Also in this embodiment, advantageously, the catch has been previously moved by a closing aid from the pre-locking position to the main locking position so as to minimize a gap even by this movement alone. The ratchet then has to be moved only very slightly in order to avoid virtually any gap (zero joint). As a result, the required space can be minimized.
Der Schwinghebel ist vorzugsweise an einer oder an mehreren Platten drehbar angebracht. Die ein oder mehreren Platten bestehen aus Stabilitätsgründen vorzugsweise aus Metall. Die ein oder mehreren Platten weisen vorzugsweise Laschen auf, mit denen die Platten an der Karosserie eines Kraftfahrzeugs oder an einer Tür oder Haube eines Kraftfahrzeugs befestigt werden können. Die ein oder mehreren Platten dienen dann einerseits der drehbaren Lagerung des Schwinghebels und andererseits der Befestigung am Kraftfahrzeug.The rocker arm is preferably rotatably mounted on one or more plates. The one or more plates consist of Stability reasons preferably made of metal. The one or more plates preferably have tabs with which the plates can be attached to the body of a motor vehicle or to a door or hood of a motor vehicle. The one or more plates then serve on the one hand the rotatable mounting of the rocker arm and on the other hand the attachment to the motor vehicle.
Der Anschlag ist vorzugsweise drehbar an der Platte gelagert. Diese Ausführungsform ermöglicht es, den Anschlag bei Bedarf aus seiner Anschlagsposition heraus zu bewegen und zwar insbesondere durch einen elektrischen Antrieb.The stopper is preferably rotatably mounted on the plate. This embodiment makes it possible to move the stop when needed from its stop position and in particular by an electric drive.
Vorzugsweise kann der Antrieb, der das Gesperre zu bewegen vermag, auch den Anschlag bewegen, um so die Zahl der benötigten Antriebe zu minimieren. Bevorzugt ist dieser Antrieb auch Teil der Zuziehhilfe.Preferably, the drive able to move the ratchet can also move the stop so as to minimize the number of drives required. Preferably, this drive is also part of the closing aid.
Der Antrieb kann in einer Ausgestaltung eine Scheibe drehen, von der ein exzentrisch angeordneter Bolzen absteht. Der Bolzen ist also entfernt von der Drehmitte oder Drehachse der Scheibe angeordnet. Der Bolzen reicht in ein Langloch des Schwinghebels für ein Bewegen des Gesperres hin. Damit ist gemeint, dass ein Drehen der Scheibe ein Verschwenken des Schwinghebels und dadurch auch ein Bewegen des Gesperres bewirkt.In one embodiment, the drive can rotate a disk from which an eccentrically arranged bolt protrudes. The bolt is thus arranged away from the center of rotation or axis of rotation of the disc. The bolt extends into a slot of the rocker arm for moving the locking mechanism out. This means that a rotation of the disc causes a pivoting of the rocker arm and thereby also a movement of the locking mechanism.
Der Bolzen wird alternativ oder ergänzend dazu genutzt, um den Anschlag geeignet zu bewegen. Insbesondere ist es so vorteilhaft möglich, den Anschlag aus seiner Anschlagsposition heraus zu bewegen, nachdem in diesen die genannte Last eingeleitet worden ist. Das Herausbewegen aus der Anschlagsposition ermöglicht es dann, das Gesperre für eine Verringerung des Spalts zu bewegen.The bolt is alternatively or additionally used to move the stop suitable. In particular, it is possible in an advantageous manner to move the stop out of its stop position after said load has been introduced into it. Moving out of the stop position then allows the ratchet to move to reduce the gap.
Die drehbaren Komponenten der Schließvorrichtung können durch Federn vorgespannt sein, um Komponenten in gewünschte Stellungen durch Federkraft hinein zu bewegen.The rotatable components of the locking device may be biased by springs to move components into desired positions by spring force.
In einer alternativen, nicht dargestellten Ausführungsform kann ein Zuziehen der Haube insbesondere auf eine Nullfuge bzw. ein 0-Spaltmaß über die Sperrklinke erfolgen. In diesem Fall bildet die Drehfalle vorzugsweise die Drehachse für das Schloss. Der Antrieb wirkt hierbei auf die Sperrklinke und ermöglicht es somit, die Haube nach einem Schließen des Gesperres in ein 0-Spaltmaß zu verfahren. Diese Ausführungsform stellt eine eigenständige Erfindung unabhängig von dem Anschlag dar, kann aber mit den vorgenannten Merkmalen kombiniert werden. Die Sperrklinke bildet dann einen Schwinghebel, der durch einen Antrieb angetrieben werden kann, um so einen Spalt zu minimieren.In an alternative, not shown embodiment, a closing of the hood can be done in particular on a zero joint or a 0-gap dimension on the pawl. In this case, the rotary latch preferably forms the axis of rotation for the lock. The drive acts on the pawl and thus makes it possible to move the hood after closing the locking in a 0-gap. This embodiment represents an independent invention independent of the stop, but can be combined with the aforementioned features. The pawl then forms a rocker arm which can be driven by a drive so as to minimize a gap.
Die Erfindung bezieht sich vorzugsweise auf ein Schloss für eine Haube eines Kraftfahrzeuges, insbesondere für eine Motorhaube. In den heutigen Fahrzeugen wird hierbei ein Spaltmaß oder eine Fuge von etwa fünf Millimetern vorgesehen. Dieses Spaltmaß ist notwendig, da die Haube beim Schließen einen Überhub von etwa 5 mm durchläuft. Dieser Überhub bedingt, dass zwischen der Haube und den Anbauteilen, wie beispielsweise dem Kühlergrill oder dem Scheinwerfer, ein Spaltmaß von mindestens 5 mm vorhanden sein muss.The invention preferably relates to a lock for a hood of a motor vehicle, in particular for a hood. In today's vehicles in this case a gap or a gap of about five millimeters is provided. This gap is necessary because the hood when closing passes through an overstroke of about 5 mm. This overstroke requires that between the hood and the attachments, such as the grille or the headlight, a gap of at least 5 mm must be present.
Um dieses Spaltmaß nach Möglichkeit auf Null reduzieren zu können, wird in einer Ausführungsform, die eine eigenständige Erfindung darstellt, eine Tür oder Klappe, so zum Beispiel eine Motorhaube, in einer Vorrast aufgefangen und mittels eines vorzugsweise elektromotorischen Antriebes von der Vorrast in die Hauptrast weiterbewegt. Hierzu können zum Beispiel die aus Servoschlössern bekannten Zuziehelemente zum Einsatz kommen. Ein Zuziehen erfolgt insbesodnere über die Drehfalle.In order to reduce this gap to zero as possible, in one embodiment, which is an independent invention, a door or flap, such as a hood, caught in a preliminary catch and moved by means of a preferably electric motor drive from the pre-rest in the main rast , These can, for example, from servo locks known Zuziehelemente come used. A crawl takes place especially on the catch.
In einer weiteren Ausführungsvariante weist die Drehfalle eine Vorrast und eine Hauptrast auf, in die das Haubenschloss beim Schließen der Frontklappe hineingelangt. Nach dem Erreichen der Hauptrast würde dann die Drehfalle in eine Überhubposition von beispielsweise sechs Millimetern mittels eines Antriebes gezogen werden. Hierzu wird eine dritte Rastposition zum Beispiel an der Drehfalle vorgesehen.In a further embodiment variant, the rotary latch has a preliminary catch and a main catch, into which the hood lock comes in when closing the front flap. After reaching the main load then the catch would be pulled in an overstroke of, for example, six millimeters by means of a drive. For this purpose, a third detent position is provided, for example, on the rotary latch.
In einer weiteren Ausführungsvariante wird die gesamte Schlosseinheit in eine 0-Fugen-Position bewegt. Hierbei wird das Schloss in einem Exzenterantrieb gelagert aufgenommen werden, so dass das Schloss in einer überhöhten Stellung schließen würde. Nach dem Schließen des Schlosses wird dann mittels des Antriebes das gesamte Schloss insbesondere elektromotorisch angetrieben verschwenkt, so dass die Tür oder Klappe wiederum in eine 0-Fugen-Position bewegt werden kann.In a further embodiment, the entire lock unit is moved in a 0-joint position. Here, the lock will be accommodated mounted in an eccentric drive, so that the castle would close in an excessive position. After closing the lock, the entire lock is then in particular driven by an electric motor pivoted by means of the drive, so that the door or flap in turn can be moved in a 0-joint position.
Die Beispiele verdeutlichen, dass es verscheidene Wege gibt, um das Spaltmaß zu reduzieren. Es ist dafür nicht erforderlich, das Schloss insgesamt zu bewegen. Es kann genügen, die Drehfalle durch einen Antrieb zu bewegen.The examples illustrate that there are several ways to reduce the gap. It is not necessary to move the lock as a whole. It may be sufficient to move the catch by a drive.
Der Erfindung liegt in einer Ausgestaltung das technische Problem zugrunde, einen derartigen Schließvorrichtung so weiterzuentwickeln, dass mit einfachen Mitteln ein möglichst geringes Spaltmaß zwischen Karosserie und Tür bzw. Haube zur Verfügung gestellt werden kann.The invention is in one embodiment, the technical problem of further developing such a locking device so that with simple means the smallest possible gap between the body and door or hood can be provided.
Zur Lösung dieser technischen Problemstellung ist ein gattungsgemäßer Schließvorrichtung im Rahmen der Erfindung dadurch gekennzeichnet, dass die Schließ- und/oder Öffnungseinrichtung außenseitig am Schlossgehäuse zu dessen Verstellung gegenüber einem ortsfesten Basiselement im Zuge eines Schließ-/Öffnungsvorganges angreift.To solve this technical problem, a generic locking device in the invention is characterized in that the closing and / or opening device on the outside on Lock housing attacks to its adjustment relative to a stationary base element in the course of a closing / opening process.
Da das Schlossgehäuse typischerweise karosserieseitig angeordnet ist, also an einer Kraftfahrzeugkarosserie eine Anordnung erfährt bzw. an die Kraftfahrzeugkarosserie angeschlossen ist, handelt es sich bei dem ortsfesten Basiselement um einen Bestandteil dieser Kraftfahrzeugkarosserie. Im Allgemeinen findet sich das erfindungsgemäße Kraftfahrzeugtürschloss bzw. Haubenschloss im Bereich eines oberen Frontträgers an der Front der Kraftfahrzeugkarosserie, der typischerweise horizontal angeordnet ist oder verläuft.Since the lock housing is typically arranged on the body side, ie undergoes an arrangement on a motor vehicle body or is connected to the motor vehicle body, the stationary base element is a component of this motor vehicle body. In general, the motor vehicle door lock or hood lock according to the invention is located in the region of an upper front carrier on the front of the motor vehicle body, which is typically arranged or extends horizontally.
Dabei ist die Auslegung vorteilhaft so getroffen, dass das Schlossgehäuse um eine Achse bzw. Drehachse schwenkbar an das fragliche Basiselement angeschlossen ist. Das heißt, die Verstellung des Schlossgehäuses im Zuge des Schließ-/Öffnungsvorganges korrespondiert zu einer Schwenkbewegung des Schlossgehäuses um die fragliche Achse bzw. Drehachse. Dazu wird die Achse respektive Drehachse im Allgemeinen derart definiert, dass im Beispielfall der obere Frontträger der Kraftfahrzeugkarosserie mit einem entsprechenden Bolzen oder Stift ausgerüstet ist, auf dem das Schlossgehäuse drehbar gelagert wird.The design is advantageously made such that the lock housing is pivotally connected to the base element in question about an axis or axis of rotation. That is, the adjustment of the lock housing in the course of the closing / opening operation corresponds to a pivoting movement of the lock housing about the axis in question or axis of rotation. For this purpose, the axis or axis of rotation is generally defined such that in the example, the upper front support of the vehicle body is equipped with a corresponding pin or pin on which the lock housing is rotatably mounted.
Um an dieser Stelle eine besonders stabile Auslegung zu erreichen, wird im Allgemeinen der Schlosskasten drehbar auf dem fraglichen Bolzen gelagert. Demgegenüber ist der Schlossdeckel mit dem Schlosskasten verbunden und wird bei einer Schwenkbewegung des Schlosskastens gleichsam mitgenommen.In order to achieve a particularly stable design at this point, the lock case is generally rotatably mounted on the bolt in question. In contrast, the lock cover is connected to the lock case and is taken along during a pivoting movement of the lock case as it were.
Der beschriebene Schließ-/Öffnungsvorgang kann grundsätzlich mechanisch vorgenommen werden. Dazu mag beispielsweise ein Bowdenzug auf die Schließ- und/oder Öffnungseinrichtung arbeiten, der sich manuell betätigen lässt. Im Regelfall ist jedoch ein motorischer Antrieb für die Schließ- und/oder Öffnungseinrichtung vorgesehen. Dabei hat es sich bewährt, wenn der motorische Antrieb exzentrisch auf die Schließ-/Öffnungsvorrichtung arbeitet. Außerdem ist es vorteilhaft, wenn der motorische Antrieb erst dann die Schließ- und oder Öffnungseinrichtung beaufschlagt, wenn sich das Türschloss in seiner Hauptraststellung befindet.The described closing / opening process can basically be carried out mechanically. For example, this may include a Work Bowden cable on the closing and / or opening device that can be operated manually. As a rule, however, a motor drive for the closing and / or opening device is provided. It has been proven that the motor drive works eccentrically on the closing / opening device. Moreover, it is advantageous if the motor drive only then acts on the closing and or opening device when the door lock is in its main latching position.
Im Allgemeinen setzt sich die Schließ- und/oder Öffnungseinrichtung im Wesentlichen aus einer Schwinge und einer am Schlossgehäuse angreifenden Klinke zusammen. Mit Hilfe der Schwinge können relativ große Drehmomente auf das Schlossgehäuse ausgeübt werden, selbst wenn mit einem klein bauenden motorischen Antrieb gearbeitet wird, der eine eher geringe Kraft aufbringt.In general, the closing and / or opening device essentially consists of a rocker and a pawl acting on the lock housing. With the help of the rocker relatively large torques can be exerted on the lock housing, even when working with a small-build motor drive, which applies a rather small force.
Die Schwinge ist meistens drehbar an das Basiselement angeschlossen. Dabei hat es sich bewährt, wenn die Schwinge und das Schlossgehäuse gleichachsig drehbar an das Basiselement angeschlossen werden. In diesem Fall fungiert also der Bolzen am oberen Frontträger der Kraftfahrzeugkarosserie vorteilhaft als gemeinsame Drehachse für einerseits das Schlossgehäuse und andererseits die Schwinge. Außerdem wird hierdurch ein besonders kompakter und wenig ausladender Aufbau zur Verfügung gestellt.The rocker is usually rotatably connected to the base member. It has proven useful if the rocker and the lock housing are connected coaxially rotatable to the base element. In this case, therefore, the bolt acts on the upper front support of the vehicle body advantageous as a common axis of rotation for one hand, the lock housing and on the other hand, the rocker. In addition, this provides a particularly compact and less bulky construction available.
Die Klinke ist ihrerseits im Allgemeinen drehbar auf der Schlinge gelagert. Dabei mag die Klinke mit Hilfe einer Feder vorgespannt werden. Außerdem hat es sich bewährt, wenn die Klinke einen Vorsprung am Schlossgehäuse hintergreift. Dieser Vorsprung am Schlossgehäuse kann aus Stabilitätsgründen vorteilhaft am Schlosskasten ausgebildet werden.The pawl in turn is generally rotatably mounted on the sling. The latch may be biased by means of a spring. Moreover, it has proven useful when the pawl engages behind a projection on the lock housing. For reasons of stability, this projection on the lock housing can advantageously be formed on the lock case.
Zur Betätigung der Schwinge und zu ihrer Verschwenkung um die gemeinsame Drehachse mit dem Schlossgehäuse ist die Schwinge größtenteils mit einem Langloch zum Eingriff eines Betätigungszapfens ausgerüstet. Der Betätigungszapfen wird seinerseits vorteilhaft mit Hilfe des motorischen Antriebes beaufschlagt.For actuating the rocker and for pivoting about the common axis of rotation with the lock housing, the rocker is largely equipped with a slot for engagement of an actuating pin. The actuating pin is in turn advantageously applied by means of the motor drive.
Dabei ist die Auslegung regelmäßig so getroffen, dass der Betätigungszapfen auf einer Abtriebs scheibe angeordnet ist. Die Abtriebsscheibe lässt sich in Rotationen mit Hilfe eines Motors respektive Elektromotors versetzen. Der Elektromotor verfügt an seiner Abtriebswelle über eine Schnecke, die in eine außenrandseitige Verzahnung der Abtriebsscheibe eingreift, um diese im Gegenuhrzeigersinn oder im Uhrzeigersinn um eine zugehörige Achse zu verschwenken. Daraus resultieren Bewegungen des Betätigungszapfens auf einem Kreisbogen, und zwar innerhalb des Langloches der Schwinge. Zur prinzipiellen Auslegung eines solchen motorischen Antriebes sei auf die
Das heißt, der Betätigungszapfen vollführt innerhalb des Langloches der Schwinge vom motorischen Antrieb initiierte Kreisbogenbewegungen. Auf diese Weise lassen sich die Schwinge und mit ihr das Schlossgehäuse um die gemeinsame Drehachse gegenüber dem Basiselement verschwenken. Denn eine Schwenkbewegung der Schwinge hat zugleich zur Folge, dass das Schlossgehäuse über die Klinke bei der Drehbewegung der Schwinge mitgenommen wird.
Im Ergebnis wird ein Schließvorrichtung zur Verfügung gestellt, welche besonders geeignet ist, um geringe Spaltbreiten zwischen zugehöriger Tür bzw. Haube und Karosserie zur Verfügung stellen zu können, die sich bis auf 0 mm 20 oder nahezu 0 mm einstellen lassen. Das erreicht die Erfindung im Kern dadurch, dass mit Hilfe der Schließ- und/oder Öffnungseinrichtung das gesamte Schlossgehäuse gegenüber dem Basiselement bzw. einem oberen und meistens horizontal angeordneten Frontträger der Kraftfahrzeugkarosserie verschwenkt wird. Das heißt, die Schließ- und/oder Öffnungseinrichtung greift bei dieser Ausführungsform ausdrücklich nicht an einem im zugehörigen Schlosskasten gelagerten Gesperre an.That is, the actuating pin performs inside the long hole of the rocker initiated by the motor drive circular arc movements. In this way, the rocker and with it the lock housing can be pivoted about the common axis of rotation relative to the base member. Because a pivoting movement of the rocker has the consequence that the lock housing is taken over the pawl during the rotational movement of the rocker.
As a result, a locking device is provided, which is particularly suitable for providing small gap widths between the associated door or hood and body, which can be set to 0
Vielmehr wird das Gesperre beim Schließen der Tür respektive Haube zunächst in eine Hauptschließstellung bzw. Hauptraststellung überführt. Diese Position startet den erfindungsgemäßen Zuziehvorgang oder Schließvorgang.
Bei diesem Zuzieh- oder Schließvorgang wird dann das gesamte Schlossgehäuse mit dem in Hauptrast befindlichen Gesperre und folglich hierin gefangenen Schließbolzen um die Drehachse gegenüber der Kraftfahrzeugkarosserie verschwenkt. Das kann besonders feinfühlig und im Vergleich zu einer beispielsweise an der Drehfalle angreifenden Zuziehbewegung mit viel größeren Hebelarmen und dementsprechend größeren Drehmomenten erfolgen. Dadurch lassen sich praktisch beliebige Spaltbreiten zwischen der Tür respektive Haube und der Kraftfahrzeugkarosserie realisieren, die bis hin zu 0 mm oder nahezu 0 mm hinunterreichen. Das alles gelingt unter Berücksichtigung eines einfachen und funktionsgerechten Aufbaus. Hierin sind die wesentlichen Vorteile dieser Ausführungsform zu sehen.Rather, the locking mechanism when closing the door or hood is first transferred to a main locking position or main detent position. This position starts the closing or closing process according to the invention.
In this Zuzieh- or closing process, the entire lock housing is then pivoted with the locking mechanism located in the main lock and thus captured here locking bolt about the axis of rotation relative to the vehicle body. This can be done very sensitively and compared to an attacking, for example, on the catch closing movement with much larger lever arms and correspondingly higher torques. As a result, virtually any gap widths between the door or hood and the motor vehicle body can be realized, which extend down to 0 mm or almost 0 mm. All of this succeeds considering a simple and functional design. Here are the main advantages of this embodiment.
Um Spaltbreiten zu minimieren, kann auch eine Kombination aus Zuziehhilfe und einem weiteren Antrieb für eine Spaltminimierung vorgesehen sein.In order to minimize gap widths, it is also possible to provide a combination of closing aid and a further drive for gap minimization.
Gemäß der vorliegenden Erfindung wird insbesondere ein elektrisch betätigbares Haubenschloss (E-Schloss) eingesetzt und alternativ mit einer Zuziehhilfe kombiniert.According to the present invention, in particular, an electrically operated hood lock (E-lock) is used and combined with a closing aid.
Derzeit werden die Haubenschösser regelmäßig dadurch geöffnet, dass in einem ersten Schritt, das heißt, einem ersten Ziehen des Haubenöffnungshebels das Schloss, beziehungsweise der Fanghaken des Gesperres in eine Vorrastposition gelangt, in der die Haube mittels Federkraft bereits geöffnet vorliegt, die Haube aber nicht geöffnet werden kann. Erst nach einem nochmaligen zweiten Ziehen an dem Haubenöffnungshebel gibt der Fanghaken, beziehungsweise das Gesperre den Schlossbügel der Haube frei, so dass die Haube manuell geöffnet werden kann.Currently, the hood seals are regularly opened by the fact that in a first step, that is, a first pulling the Hood opening lever the lock, or the catch hook of the locking mechanism reaches a pre-locking position in which the hood is already open by means of spring force, but the hood can not be opened. Only after a second second pull on the hood opening lever of the fishing hook, or the locking mechanism release the lock strap of the hood, so that the hood can be opened manually.
Bevorzugt wird gemäß der vorliegenden Erfindung ein elektrisch zu betätigendes Schloss (mit Zuziehhilfe) mit einer elektrisch betätigten Verstellvorrichtung kombiniert. Zur Erzielung einer 0-Fuge wird das Haubenschloss, wie in den deutschen Voranmeldungen 10 2013 109 051 sowie 10 2013 222 053 beschrieben, elektrisch verfahren, danach aber nicht manuell, sondern elektrisch betätigt das Gesperre freigeben. Ein vorteilhafter zweistufiger Öffnungsvorgang wird somit erfüllt sein. Beim Schließen wird die Haube insbesondere durch das Eigengewicht das Gesperre schließen, beziehungsweise sperren und der elektrische Verstellmechanismus wird die Haube in die 0-Fugen-Position ziehen.Preferably, according to the present invention, an electrically operated lock (with closing aid) is combined with an electrically operated adjusting device. To achieve a 0-joint, the hood lock, as described in the German Pre-Declarations 10 2013 109 051 and 10 2013 222 053, electrically traversed, but then release not manually but electrically actuated the locking mechanism. An advantageous two-stage opening process will thus be fulfilled. When closing the hood will close in particular by the weight of the locking mechanism, or lock and the electric adjustment mechanism will pull the hood in the 0-joint position.
Es wird in einer vorteilhaften Ausführungsform ein zweistufiges Gesperre eingesetzt und nach einem Erreichen einer Vorrast beim Schließen der Haube das Gesperre in eine Hauptrast elektromotorisch zugezogen.It is used in an advantageous embodiment, a two-stage locking mechanism and after reaching a pre-restraint when closing the hood, the locking mechanism in a main ratchet pulled by an electric motor.

Mit einem Antrieb 6 kann das Gesperre aus Drehfalle 1 und Sperrklinke 2 so bewegt werden, dass ein Türspalt oder Klappenspalt verkleinert werden kann. Der Antrieb 6 verfügt zu diesem Zweck insbesondere über einen Elektromotor 7 und eine mit der Welle des Motors verbundene Schnecke 8. Der Motor 7 kann eine Drehbewegung der Schnecke 8 bewirken. Eine Drehbewegung der Schnecke 8 bewirkt über ein vorzugsweise vorgesehenes mehrstufiges Getriebe 9 eine Drehbewegung einer Scheibe 10. Von der Scheibe 10 steht ein Bolzen 11 senkrecht ab. Der Bolzen 11 ist an der Scheibe 10 befestigt. Der Bolzen 11 weist einen Abstand zur Drehmitte der Scheibe 10 auf und ist also exzentrisch angeordnet. Der Bolzen 11 reicht in ein Langloch 12 eines schwenkbar gelagerten Hebels bzw. Schwinghebel 13 hinein. Der Schwinghebel 13 ist durch die Achse bzw. Welle 5 schwenkbar gelagert. Ein Drehen der Scheibe 10 bewirkt damit ein Verschwenken des Schwinghebels 13.The
With a
Der Hebel sowie die Schlossplatte 3 sind starr mit der Welle 5 verbunden. Ein Verschwenken des Hebels 13 bewirkt damit synchron ein Verschwenken der Schlossplatte 3.
Von der Welle 5 aus gesehen erstrecken sich Schlossplatte 3 und Schwinghebel 13 in die gleiche Richtung und zwar vorzugsweise in Richtung des Antriebs 6, um so den Bauraum gering zu halten. Der Schwinghebel 13 erstreckt sich über die Schlossplatte 3 hinaus und zwar insbesondere über das Einlaufmaul der Schlossplatte 3 hinaus, also über den Bereich hinaus, in den ein Schließbolzen gelangt, wenn eine zugehörige Tür oder Klappe geschlossen wird. Hierdurch werden günstige Hebelverhältnisse bereitgestellt, um den Schwinghebel 13 mit geringer elektrischer Leistung für ein Verkleinern eines Spalts einer Tür oder Klappe verschwenken zu können.
Darüber hinaus umfasst die Schließvorrichtung eine in den

Die Schließvorrichtung umfasst einen stegförmigen Anschlag 20, der durch eine Achse oder Welle 21 drehbar vorzugsweise an der Platte 14 befestigt ist. Insbesondere von der Platte 14 steht ein Bolzen 22 senkrecht ab, der eine Schwenkbewegung des Anschlags 20 zu begrenzen vermag (siehe
Von der Achse oder Welle 21 ausgesehen erstreckt sich zum Beispiel ein Bügel 24, der der Steuerung der Bewegung des Anschlags 20 dient. Zusammen mit dem Anschlag 20 bildet der Bügel 24 in einer Ausführungsform näherungsweise eine U-Form. Der Bügel 24 liegt grundsätzlich an dem Bolzen 11 an. Wird die Scheibe 10 gedreht, so wird damit auch der Bügel 24 aufgrund des Bolzens 11 bewegt. Das Bewegen des Bügels 24 bewirkt eine entsprechend synchrone Bewegung des Anschlags 20.For example, a
Der Anschlag 20 dient nicht nur als Anschlag für die Drehfalle 1, sondern auch als Anschlag für den Schwinghebel 13, wenn der Schließbolzen 18 in das Schloss einfällt. Damit dann der Anschlag 20 auch für den Schwinghebel 13 in einer bevorzugten Ausführungsform einen Anschlag darstellt, verfügen sowohl der Anschlag 20 als auch die Schwinghebel 13 über geeignet abgebogenen Laschen 25 und 26. Fällt der Schließbolzen 18 in das Schloss ein, so trifft die abgebogenen Lasche 25 des Schwinghebels 13 auf die abgebogenen Lasche 26 des Anschlags 20 auf, wie der vergrößerte Ausschnitt der
Das Schloss verfügt ferner über einen Auslösehebel 27, der ebenfalls durch die Achse bzw. Welle 5 drehbar gelagert wird. Der Auslösehebel 27 wird über einen nicht gezeigten Bowdenzug betätigt. Durch Betätigung des Bowdenzugs wird die Sperrklinke 2 aus ihrer Rastposition heraus bewegt, um anschließend eine Tür oder Klappe öffnen zu können. Der Auslösehebel 27 kann über einen Haken 28 verfügen, in den der Bowdenzug eingehängt wird.The lock also has a

Das Schlossgehäuse 100 setzt sich prinzipiell aus einem dargestellten Schlosskasten 101 und einem mit dem Schlosskasten 101 verbundenen oder verbindbaren Schlossdeckel zusammen, der jedoch nicht dargestellt ist. Während der Schlosskasten 101 metallisch und massiv ausgelegt ist, um ein darin gelagertes Gesperre 106, 107 aufnehmen zu können, ist der nicht gezeigte Schlossdeckel typischerweise aus Kunststoff hergestellt. Das Gesperre 106, 107 setzt sich wie üblich aus einer Drehfalle 106 und einer Sperrklinke 107 zusammen, die jeweils drehbar in dem Schlosskasten 101 aufgenommen werden, wie man beim Vergleich der
Zum weiteren grundsätzlichen Aufbau gehört eine Schließ- und/oder Öffnungseinrichtung 108, 109. Die Schließ- und/oder Öffnungseinrichtung 108, 109 ist in diesem Ausführungsbeispiel und nicht einschränkend als Zuzieheinrichtung 108, 109 ausgelegt und setzt sich aus einer Schwinge 108 und einer Klinke 109 zusammen. Außerdem ist ein motorischer Antrieb 110, 111 dargestellt. Der motorische Antrieb 110, 111 setzt sich aus einer Antriebsscheibe 111 und einem auf der Antriebsscheibe 111 angeordneten Betätigungszapfen 110 zusammen. Tatsächlich steht der Betätigungszapfen 110 überwiegend senkrecht auf der Antriebsscheibe 111 auf.For further basic construction includes a closing and / or

Die Antriebsscheibe 111 vollführt beim Übergang von der Funktionsstellung der
Von besonderer Bedeutung für diese Ausführungsform der Erfindung ist nun der Umstand, dass die Schließ- und/oder Öffnungseinrichtung 108, 109 bzw. die erfindungsgemäß vorgesehene Zuzieheinrichtung 108, 109 außenseitig am Schlossgehäuse 100 zur Verstellung des Schlossgehäuses 100 gegenüber dem ortsfesten Basiselement 104 im Zuge eines Schließ-/Öffnungsvorganges angreift. Dazu übergreift bzw. hintergreift die Klinke 109 einen Vorsprung 113 am Schlossgehäuse 100 bzw. einen Vorsprung 113, der vorliegend im oder am Schlosskasten 101 ausgebildet ist. Der motorische Antrieb 110, 111 arbeitet insgesamt exzentrisch auf die Schließ- und/oder Öffnungseinrichtung 108, 109, wie man beim Vergleich der

Schalter am Gesperre 106, 107 erhalten hat, dass sich nämlich das Gesperre 106, 107 in der Hauptraststellung befindet, wird der Elektromotor bestromt. Daraus resultiert eine Bewegung der Antriebsscheibe 111 im Uhrzeigersinn um ihre Achse bzw. Drehachse 112. Der das Langloch 114 in der Schwinge 108 durch greifende Betätigungszapfen 110 beaufschlagt dementsprechend die Schwinge 108 bzw. die Zuzieheinrichtung 108, 109 insgesamt exzentrisch.
