- the invention relates to a lock with an auxiliary motor, in particular a door lock for a motor vehicle, with the features specified in the preamble of claim 1.
- Such a lock with auxiliary motor is known from the international publication WO 89/02 964 and has a locking bolt which is engaged by a rotary latch in a closed position by manually closing the vehicle door and is locked in front of a catch of the rotary latch after the engagement of a pawl.
- the locking bolt can be rotated by an auxiliary motor about an eccentric axis from a pre-closed position to a main closed position.
- the elastic door seal which is less compressed in the pre-closing position and more compressed in the main closing position, via the rotary latch locked by the pawl in the pre-closing position and in the main closing position, causes a torque on the axis of rotation of a support disk which can be rotated by the auxiliary motor, on which is attached at a radial distance to the axis of rotation of the locking bolt. It is therefore an additional locking device with a radially incident in front of a support shoulder of the support disc Locking body required, but which can only prevent the support disk and thus the locking bolt from turning back in the main closed position.
- the invention has for its object to provide a lock with an auxiliary motor according to the preamble of claim 1, in which the auxiliary motor and related components are less stressed and the adjustment of the locking bolt from the pre-closed position in the main closed position runs more harmoniously.
- the auxiliary motor can be dimensioned small, with its adjusting force being dimensioned only so that the motor Adjustment of the locking bolt in a given direction of rotation under the loads to be expected no unintentional turning back of the locking bolt takes place.
- the motorized pivoting of the locking bolt each from a dead center position by approximately 180 ° to approximately a dead center position results in a largely jerk-free, harmonious adjustment of the locking bolt and thus the wing to be locked by the lock or a vehicle door.
- the lock shown in Fig. 1 is provided on a vehicle door of a motor vehicle and has a lock latch designed as a fork latch 1.
- the fork latch 1 can be pivoted on a lock plate 2 connected to the vehicle door from an open position via a pre-latching position into the main latching position shown, in which a locking bolt 3 or the like is engaged by a leg 4 of the fork latch 1 in a known manner.
- the fork latch 1, which has a preliminary latch 5 and a main latch 6, is in the main latching position shown from a position on the lock plate 2 between a release position releasing the fork latch 1 and the illustrated locking position about the axis 7 pivotable pawl 8 secured against a shift to the open position.
- the pawl 8 is loaded by a leg spring 9 shown by a dash-dotted line in the locking position and the fork latch 1 by a spring, not shown, in the open position.
- the locking bolt 3, which is circular in cross section, is rotatably arranged about an axis 11 eccentric to its axis 10 on a locking wedge 12 which is fastened to a vertical column of a door frame receiving the vehicle door.
- FIG. 1a the position corresponding to FIG. 1 of the vehicle door 13 relative to the pillar 14 of the door frame receiving the vehicle door 13 is illustrated in a basic illustration.
- the locking bolt is in its pre-closing position and the fork latch is in its main latching position in this position.
- the locking bolt 3 can be displaced from an auxiliary motor (not shown) by an angle of approximately 180 degrees about the eccentric axis 11 parallel to the axis 10 of the locking bolt 3 from the pre-closing position shown in FIG. 1 to the main closing position shown in FIG. 2.
- the locking wedge 12 is relatively H, which is twice the eccentricity E of the axis 10 of the locking bolt 3 compared to its eccentric Axis 11 corresponds to the fork latch 2.
- the relative path of the locking wedge 4 relative to the fork latch 2 is shown in FIG. 2.
- the locking bolt 3 can be rotated in the reverse position from the auxiliary motor (not shown) from its main closing position corresponding to FIG. 2 into the pre-closing position according to FIG. 1. Since, in the exemplary embodiment, the locking bolt 3 is in a dead center position in the pre-closing position and in the main closing position, the motor movement of the vehicle door from the pre-closing position to the main closing position and vice versa into the pre-closing position is particularly harmonious in the course.
- a switch 15 shown symbolically in FIGS. 1 and 2 detects the latching position of the fork latch 1 when the lock is closed and switches the auxiliary motor on in the pre-closing position until the main closing position is reached. Since the fork latch 1 is already in its main latching position and the locking blade 8 is in its locked position, no further displacement of the parts is required to ensure that the pawl 8 secures the fork latch 1 before moving to an open position.
- the auxiliary motor not shown, is formed in the exemplary embodiment by an electric motor and a downstream transmission which interacts, for example, with a gearwheel connected to the locking bolt 3.

- the third leg 12c which forms a protection for the locking bolt 3, lies opposite a vertical end face, not shown, of the vehicle door.
- the leg 12a in FIG. 3 is connected to this column 14.
- the lock can be realized in numerous designs that differ from the exemplary embodiment.
- the lock latch designed as a fork latch in the exemplary embodiment can be designed as a sliding latch.
- the lock latch cannot be secured by a pawl before being moved to an open position.
- Rotation of the locking bolt from the pre-closing position into the main closing position and, if applicable, from the main closing position to the pre-closing position can also take place with a different twisting angle in a desired direction of rotation, deviating from the particularly advantageous twisting angle of 180 degrees. It is also not necessary for the locking bolt to be fastened to a locking wedge.
- the locking bolt which deviates from the exemplary embodiment, is not rotatably mounted on both end regions, but only on one end region.
- the cross section of the locking bolt is preferably circular.
- other cross-sectional shapes of the locking bolt are also possible, the cross-sectional shape being used to control the relative movement of the locking bolt with respect to the lock latch.
- the lock is also suitable for other applications in which, for example, a component which can be locked by the lock is difficult to close.
Description
Die Erfindung betrifft ein Schloß mit Hilfsmotor, insbesondere ein Türschloß für ein Kraftfahrzeug, mit den im Oberbegriff des Patentanspruches 1 angegebenen Merkmalen.The invention relates to a lock with an auxiliary motor, in particular a door lock for a motor vehicle, with the features specified in the preamble of claim 1.
Ein derartiges Schloß mit Hilfsmotor ist durch die internationale Veröffentlichung WO 89/02 964 bekannt und weist einen Schließbolzen auf, der in einer Vorschließstellung durch manuelles Schließen der Fahrzeugtür von einer Drehfalle hintergriffen wird und nach dem Einfallen einer Sperrklinke vor eine Raste der Drehfalle verriegelt ist. Der Schließbolzen ist von einem Hilfsmotor um eine exzentrische Achse aus einer Vorschließstellung in eine Hauptschließstellung drehbar. Besonders nachteilig ist, daß die zur Abdichtung der geschlossenen Fahrzeugtür in Vorschließstellung weniger und in Hauptschließstellung stärker komprimierte elastische Türdichtung über die von der Sperrklinke verriegelte Drehfalle in der Vorschließstellung sowie in der Hauptschließstellung ein Drehmoment an der Drehachse einer von dem Hilfsmotor drehbaren Stützscheibe bewirkt, an der mit radialem Abstand zur Drehachse der Schließbolzen befestigt ist. Es ist deshalb eine zusätzliche Sperreinrichtung mit einem radial vor eine Stützschulter der Stützscheibe einfallenden Sperrkörper erforderlich, der jedoch lediglich in Hauptschließstellung ein Rückdrehen der Stützscheibe und damit des Schließbolzens verhindern kann. Beim schwungvollen Einschwenken der Fahrzeugtür wird in Vorschließstellung beim Hintergreifen des Schließbolzens durch die Drehfalle und anschließendem Verriegeln durch die Sperrklinke ebenfalls ein hohes Belastungs-Drehmoment an der den Schließbolzen exzentrisch aufnehmenden Stützplatte bewirkt.Such a lock with auxiliary motor is known from the international publication WO 89/02 964 and has a locking bolt which is engaged by a rotary latch in a closed position by manually closing the vehicle door and is locked in front of a catch of the rotary latch after the engagement of a pawl. The locking bolt can be rotated by an auxiliary motor about an eccentric axis from a pre-closed position to a main closed position. It is particularly disadvantageous that the elastic door seal, which is less compressed in the pre-closing position and more compressed in the main closing position, via the rotary latch locked by the pawl in the pre-closing position and in the main closing position, causes a torque on the axis of rotation of a support disk which can be rotated by the auxiliary motor, on which is attached at a radial distance to the axis of rotation of the locking bolt. It is therefore an additional locking device with a radially incident in front of a support shoulder of the support disc Locking body required, but which can only prevent the support disk and thus the locking bolt from turning back in the main closed position. When the vehicle door swings in with a swing in the pre-closed position, when the locking bolt reaches behind the locking bolt and then locks through the pawl, a high loading torque is also exerted on the support plate which receives the locking bolt eccentrically.
Der Erfindung liegt die Aufgabe zugrunde, ein Schloß mit Hilfsmotor nach dem Oberbegriff des Patentanspruches 1 anzugeben, bei dem der Hilfsmotor bzw. damit in Verbindung stehende Bauteile weniger beansprucht sind und das Verstellen des Schließbolzens von der Vorschließstellung in die Hauptschließstellung harmonischer verläuft.The invention has for its object to provide a lock with an auxiliary motor according to the preamble of claim 1, in which the auxiliary motor and related components are less stressed and the adjustment of the locking bolt from the pre-closed position in the main closed position runs more harmoniously.
Diese Aufgabe ist bei dem gattungsgemäßen Schloß durch die im Kennzeichen des Patentanspruches 1 angegebenen Merkmale gelöst. Besonders vorteilhaft ist, daß sich in Vorschließstellung und in Hauptschließstellung der Schließbolzen etwa in einer Totpunktlage befindet, in der ein von dem Schloß verriegelter Flügel, beispielsweise eine Fahrzeugtür, selbst unter Belastung des Flügels an der exzentrischen Achse des Schließbolzens kein oder nahezu kein Drehmoment bewirkt. Der Flügel bzw. die Fahrzeugtür kann mit Wucht geschlossen werden, ohne dabei den Hilfsantrieb bzw. damit in Verbindung stehende Bauteile übermäßig zu belasten. Der Hilfsantrieb kann somit den Schließbolzen in Vorschließstellung und in Hauptschließstellung mit einer geringen Selbsthemmung festhalten. Der Hilfsmotor kann gering dimensioniert sein, wobei seine Verstellkraft lediglich so zu bemessen ist, daß beim motorischen Verstellen des Schließbolzens in eine vorgegebene Drehrichtung unter den zu erwartenden Belastungen kein unbeabsichtigtes Rückdrehen des Schließbolzens erfolgt. Durch das motorische Verschwenken des Schließbolzens jeweils aus einer Totpunktlage um etwa 180° in etwa eine Totpunktlage wird ein weitgehend ruckfreies, harmonisches Verstellen des Schließbolzens und damit des von dem Schloß zu verschließenden Flügels bzw. einer Fahrzeugtür bewirkt.This object is achieved in the generic lock by the features specified in the characterizing part of claim 1. It is particularly advantageous that in the pre-closed position and in the main closed position the locking bolt is approximately in a dead center position in which a wing locked by the lock, for example a vehicle door, causes no or almost no torque even when the wing is loaded on the eccentric axis of the locking bolt. The wing or the vehicle door can be closed with force without unduly stressing the auxiliary drive or the components connected with it. The auxiliary drive can thus hold the locking bolt in the pre-closing position and in the main closing position with a low level of self-locking. The auxiliary motor can be dimensioned small, with its adjusting force being dimensioned only so that the motor Adjustment of the locking bolt in a given direction of rotation under the loads to be expected no unintentional turning back of the locking bolt takes place. The motorized pivoting of the locking bolt each from a dead center position by approximately 180 ° to approximately a dead center position results in a largely jerk-free, harmonious adjustment of the locking bolt and thus the wing to be locked by the lock or a vehicle door.

Das in Fig. 1 dargestellte Schloß ist an einer Fahrzeugtür eines Kraftfahrzeugs vorgesehen und weist eine als Gabelfalle 1 ausgebildete Schloßfalle auf. Die Gabelfalle 1 ist bei dem Ausführungsbeispiel an einem mit der Fahrzeugtür verbundenen Schloßblech 2 aus einer Offenstellung über eine Vorraststellung in die dargestellte Hauptraststellung schwenkbar, in der in bekannter Weise ein Schließbolzen 3 oder dergleichen von einem Schenkel 4 der Gabelfalle 1 hintergriffen ist. Die eine Vorrast 5 und eine Hauptrast 6 aufweisende Gabelfalle 1 ist in der dargestellten Hauptraststellung von einer an dem Schloßblech 2 zwischen einer die Gabelfalle 1 freigebenden Lösestellung und der dargestellten Sperrstellung um die Achse 7 schwenkbaren Sperrklinke 8 vor einer Verlagerung in die Offenstellung gesichert. Die Sperrklinke 8 ist von einer durch eine strichpunktierte Linie dargestellten Schenkelfeder 9 in die Sperrstellung und die Gabelfalle 1 von einer nicht dargestellten Feder in die Offenstellung belastet. Der im Querschnitt kreisförmige Schließbolzen 3 ist um eine zu seiner Achse 10 exzentrischen Achse 11 an einem Schließkeil 12 verdrehbar angeordnet, der an einer vertikalen Säule eines die Fahrzeugtür aufnehmenden Türrahmens befestigt ist.The lock shown in Fig. 1 is provided on a vehicle door of a motor vehicle and has a lock latch designed as a fork latch 1. In the exemplary embodiment, the fork latch 1 can be pivoted on a
In Fig. 1a ist die Fig. 1 entsprechende Stellung der Fahrzeugtür 13 gegenüber der Säule 14 des die Fahrzeugtür 13 aufnehmenden Türrahmens in einer Prinzipdarstellung veranschaulicht. Wie bereits ausgeführt, befinden sich in dieser Stellung der Schließbolzen in seiner Vorschließstellung und die Gabelfalle in ihrer Hauptraststellung.In FIG. 1a, the position corresponding to FIG. 1 of the
Der Schließbolzen 3 ist von einem nicht dargestellten Hilfsmotor um einen Winkel von etwa 180 Grad um die zur Achse 10 des Schließbolzens 3 parallele exzentrische Achse 11 aus der in Fig. 1 dargestellten Vorschließstellung in die in Fig. 2 abgebildete Hauptschließstellung verlagerbar. Wie auf der linken Bildseite in Fig. 2 durch unterbrochene Linien dargestellt ist, wird beim Verdrehen des Schließbolzens 3 aus seiner Vorschließstellung in seine Hauptschließstellung der Schließkeil 12 relativ um das Maß H, das der doppelten Exzentrizität E der Achse 10 des Schließbolzens 3 gegenüber seiner exzentrischen Achse 11 entspricht, zu der Gabelfalle 2 verlagert. Der Einfachheit halber ist in Fig. 2 der relative Weg des Schließkeils 4 gegenüber der Gabelfalle 2 dargestellt. Es ist jedoch selbstverständlich, daß sich bei dieser Verdrehung des Schließbolzens 3 nicht der am Fahrzeug feststehende Schließkeil 12 verstellt, sondern umgekehrt die Fahrzeugtür mit dem Schloßblech 2, der Gabelfalle 1 und der Sperrklinke 8 sowie weiterer Teile um das Maß H zu dem Schließkeil 12 verlagert wird. Bei der vorliegenden Ausführung ist in umgekehrter Weise der Schließbolzen 3 von dem nicht dargestellten Hilfsmotor aus seiner Fig. 2 entsprechenden Hauptschließstellung in die Vorschließstellung gemäß Fig. 1 verdrehbar. Da sich bei dem Ausführungsbeispiel der Schließbolzen 3 in Vorschließstellung und in Hauptschließstellung jeweils in einer Totpunktlage befindet, ist die motorische Bewegung der Fahrzeugtür von der Vorschließstellung in die Hauptschließstellung und umgekehrt in die Vorschließstellung im Verlauf besonders harmonisch. Während der Verlagerung der Fahrzeugtür von der Vorschließstellung in die Hauptschließstellung wird eine im Türrahmen angeordnete Türdichtung elastisch verformt, die dadurch eine die Fahrzeugtür in die Offenstellung belastende Widerstandskraft bewirkt. Die Fahrzeugtür läßt sich jedoch leicht schließen, da bereits ein leichter Türschlag ausreichend ist, um die Fahrzeugtür in die Vorschließstellung und mit Unterstützung des Hilfsmotors von der Vorschließstellung gegen die Widerstandskraft der Türdichtung in die Hauptschließstellung zu verlagern. Das in den Figuren 1 und 2 übertrieben dargestellte Spiel zwischen dem Schließbolzen 3 und den Schenkeln 4, 4′ der Gabelfalle 1 ist bei dem Ausführungsbeispiel in Wirklichkeit nur gering, so daß beim Verdrehen des Schließbolzens 3 keine oder nahezu keine Geräusche auftreten. Die Fahrzeugtür wird außerdem von dem Schließkeil 12 in an sich bekannter Weise gestützt. Ein in den Figuren 1 und 2 symbolisch dargestellter Schalter 15 erfaßt beim Schließen des Schlosses die Raststellung der Gabelfalle 1 und schaltet den Hilfsmotor in Vorschließstellung bis zum Erreichen der Hauptschließstellung ein. Da sich die Gabelfalle 1 bereits in ihrer Hauptraststellung und die Sperrklinge 8 in ihrer Sperrstellung befindet, ist keine weitere Verlagerung der Teile erforderlich, um sicherzustellen, daß die Sperrklinke 8 die Gabelfalle 1 vor einer Verlagerung in eine Offenstellung sichert. Der nicht dargestellte Hilfsmotor ist bei dem Ausführungsbeispiel durch einen Elektromotor und ein nachgeschaltetes Getriebe gebildet, das beispielsweise mit einem mit dem Schließbolzen 3 verbundenen Zahnrad zusammenwirkt.The
Aus der schematischen Darstellung gemäß Fig. 2a ist ersichtlich, daß bei dem gemäß Fig. 2 in Hauptschließstellung befindlichen Schloß die Fahrzeugtür außenhautbündig und zur Säule 14 bündig ist.2a that the vehicle door is flush with the outer skin and flush with the
Der bei dem Ausführungsbeispiel verwendete Schließkeil 12 ist in Fig. 3 vergrößert in Draufsicht dargestellt. Wie man erkennt, weist der Schließkeil 12 drei seitlich zur Außenseite A gerichtete Schenkel 12a, 12b, 12c auf. Der durch ausgezogene Linien in Vorschließstellung und durch unterbrochene Linien in Hauptschließstellung dargestellte Schließbolzen 3 ist zwischen den beiden Schenkeln 12a, 12b angeordnet und um eine an den beiden Schenkeln 12a, 12b ausgebildete exzentrische Achse 11 schwenkbar mit den Schenkeln 12a, 12b verbunden. Der Dritte, einen Schutz für den Schließbolzen 3 bildende Schenkel 12c liegt einer nicht dargestellten vertikalen Stirnseite der Fahrzeugtür gegenüber. Zur Befestigung des Schließkeiles 12 an der auch in den Figuren 1b und 2b dargestellten vertikalen Säule 14 des Türrahmens ist der Schenkel 12a in Fig. 3 mit dieser Säule 14 verbunden.The
Ohne den Erfindungsgedanken aufzugeben, kann das Schloß in zahlreichen, von dem Ausführungsbeispiel abweichenden Ausführungen realisiert werden. Beispielsweise kann die bei dem Ausführungsbeispiel als Gabelfalle ausgebildete Schloßfalle als Schiebefalle ausgebildet sein. Es sind auch Ausführungen denkbar, bei denen die Schloßfalle nicht von einer Sperrklinke vor einer Verlagerung in eine Offenstellung zu sichern ist. Ein Verdrehen des Schließbolzens von der Vorschließstellung in die Hauptschließstellung und gegebenenfalls von der Hauptschließstellung in die Vorschließstellung kann auch von dem besonders vorteilhaften Verdrehwinkel von 180 Grad abweichend mit einem anderen, an sich beliebigen Verdrehwinkel in eine gewünschte Verdrehrichtung erfolgen. Es ist auch nicht erforderlich, daß der Schließbolzen an einem Schließkeil befestigt ist. Ebenso ist es vorgesehen, daß der Schließbolzen von dem Ausführungsbeispiel abweichend nicht an beiden Stirnbereichen, sondern nur an einem Stirnbereich exzentrisch drehbar gelagert ist. In bevorzugter Weise ist der Querschnitt des Schließbolzens kreisförmig. Es sind aber auch andere Querschnittsformen des Schließbolzens möglich, wobei über die Querschnittsform die Relativbewegung des Schließbolzens gegenüber der Schloßfalle zu steuern ist. Das Schloß eignet sich neben einer Verwendung beispielsweise als Tür- oder Haubenschloß oder dergleichen an einem Kraftfahrzeug auch für andere Anwendungen, bei denen beispielsweise ein von dem Schloß verschließbares Bauteil an sich schwergängig zu schließen ist.Without giving up the idea of the invention, the lock can be realized in numerous designs that differ from the exemplary embodiment. For example, the lock latch designed as a fork latch in the exemplary embodiment can be designed as a sliding latch. There are Designs are also conceivable in which the lock latch cannot be secured by a pawl before being moved to an open position. Rotation of the locking bolt from the pre-closing position into the main closing position and, if applicable, from the main closing position to the pre-closing position can also take place with a different twisting angle in a desired direction of rotation, deviating from the particularly advantageous twisting angle of 180 degrees. It is also not necessary for the locking bolt to be fastened to a locking wedge. Likewise, it is provided that the locking bolt, which deviates from the exemplary embodiment, is not rotatably mounted on both end regions, but only on one end region. The cross section of the locking bolt is preferably circular. However, other cross-sectional shapes of the locking bolt are also possible, the cross-sectional shape being used to control the relative movement of the locking bolt with respect to the lock latch. In addition to being used, for example, as a door or hood lock or the like on a motor vehicle, the lock is also suitable for other applications in which, for example, a component which can be locked by the lock is difficult to close.
