EP2397627A2 - Device for coupling and decoupling an external door handle - Google Patents

Abstract

The device has a spring elastic actuating member (11) pivoted with housing-mounted electric motor drive (10). The actuating member engages coupling members (1, 2) with actuating sections (12, 12', 13, 13') to a driving section (7) of a coupling pawl (5) to pivot the coupling pawl in a coupling or release position, where the coupling members are supported in a neutral rotational position of the coupling pawl. The driving section eccentrically drives the actuating member to the coupling pawl during release of rotation of the coupled coupling members from two of the actuating sections.

Description

The invention relates to a device for coupling and uncoupling a door outside handle with a pusher mandrel for actuating a door lock, with two about a rotation axis rotatably mounted in a housing coupling elements, which by an engagement of a mounted in the transverse direction to the axis of rotation about a pivot axis to a coupling member Clutch pawl associated with the coupling projection in a coupling recess of a release position in a rotationally fixed coupling position can be brought to each other, and with one of a housing fixed, electric motor drive pivotable, in particular resilient actuator, in a neutral rotational position of the coupling pawl-bearing coupling member with an actuating portion on a drive portion of the coupling pawl engages to pivot the latter in the coupling position or the release position.

A device of this type describes the EP 0 172 796 B1 , The device is part of an electrically operated lock with an outer door handle and an inner door handle, wherein a square mandrel portion of the outer door handle engages in a square recess of the outer door handle associated coupling member. The square-edged mandrel of the internal door handle penetrates the nut of a lock in order to retract a latch and possibly also a bolt by actuating the internal door handle. On the inner link associated with the coupling member supports a coupling pawl. The latter has a coupling projection, which engages in a coupling recess of the Au-βendrücker associated coupling member, so that rotation of the outer handle can be transferred to the nut of the castle. The coupling member has a drive portion which in the axis of rotation of the Coupling links is located. At the drive portion engages an actuating portion of an electric motor drive to move the coupling pawl from the coupling position to a release position. In the release position, the outer link actuator associated with the inner pusher coupling member is not entrained.

The EP 0 891463 B1 also describes an eccentric coupling pawl having a coupling projection engageable in a coupling recess. A drive motor for shifting the clutch pawl is firmly connected to a clutch disk carrying the pawl.

The WO 02/057 575 A1 describes an electrical coupling with a coupling pawl, which is displaceable in the plane of rotation of the coupling members. To displace the clutch pawl is an eccentric actuator at the end of a drive shaft of an electric motor.

The DE 103 19 185 A1 describes an electromechanical lock in which a coupling pawl is pivoted by a spring element having a spring arm which engages in the flight of a motor-driven worm.

The DE 199 01 758 A1 describes an electronic lock with a coupling in which the coupling recess is associated with a pivoting ring.

From the DE 38 53 828 T2 a locking device is known in which two coupling members can be brought from a coupling position into a release position by pivoting a rocker arm.

The invention has for its object to further develop a generic device nutzsvorteilhaft.

The object is achieved by the invention specified in the claims. First and foremost, it is provided that the drive section moves away from the actuating section as a result of an eccentric attack of the actuating member on the coupling pawl with respect to the axis of rotation when the coupled coupling members are rotated. The operative connection of drive section and actuator is canceled when turning. The drive section leaves its engagement position between operating sections. Control means may be provided which return one or more actuation sections into an operative position to the drive section when turning back the coupling element pivoted out of the neutral position into the neutral position. The drive section may be formed by a drive arm protruding radially outwards from the clutch pawl. The actuator may comprise two substantially mutually parallel spring legs which engage two opposite sides of the drive arm. The spring legs of the actuator may be formed by a pivotally mounted about a housing-fixed axis U-shaped spring, which are pivoted by an electric motor drive about this axis. It may be a U-shaped leaf spring, which is formed in one piece. The spring may also be formed in two parts, the leaf spring may have two separate legs, which are connected to each other in the apex area with a connecting piece. This connector may be formed by the pivot axis of the spring. It would also be conceivable to manufacture the system from a two-part spring plate with a connecting piece of a casting. The leaf spring can also be used with a connector made of metal or plastic to be splashed. The connector may also be a one-piece plastic injection molded part. With this spring element, the coupling pawl between the coupling position and release position can be switched back and forth. These control means may be formed by control slopes, which adjoin the operating sections in the circumferential direction with respect to the axis of rotation. When turning back the drive section, this is controlled by the control slopes again in the space between the two spring legs. The two coupling members may be mounted in a recess of the housing. Each of the coupling members carries an extension which has a square opening, wherein the square openings are in an alignment with each other, so that in a square opening the end of a square mandrel of an internal presser and in the other square opening the end of a square mandrel of an external presser can be inserted. If the coupling pawl is in its release position, the coupling projection does not engage in the coupling recess. If the coupling pawl, for example. Worn by the inner handle associated with the coupling member, it pivots together with the coupling member in a Innenendrückerbetätigung. The drive portion of the clutch pawl gets out of the effective range of the actuator. If the inner handle is released, it will be moved back by the force of a spring in the starting position. The drive section gets back into the effective range of the actuator. If, in the meantime, the actuating element has been pivoted by actuation of the electromotive drive, the drive section will move against one of the control bevels. The actuator can evade due to its spring elasticity. If the coupling member carrying the coupling pawl reaches its starting position, in which the coupling projection lies above the coupling recess, then the spring-biased actuating member can pivot the coupling pawl, so that the coupling projection in the coupling recess enters. The coupling projection may have an undercut. The coupling recess has a corresponding cross-sectional contour. Preferably, this undercut is formed by a dovetail profile of the coupling projection. If the inner handle is actuated in the coupling position, the outer handle is dragged along, since the two coupling members are rotatably coupled to each other in the coupling position. If the external handle is actuated, then the internal pressure associated with the coupling member is drehmit dragged. This has the consequence that can be withdrawn by pressing the outer handle, the case of a lock. Here too, when the coupling member rotates about the pusher axis, the drive section is released from the actuating member and is caught again by the actuating member when turning back. Switches in the pivoted position of the coupling members of the drive motor to the actuator, so the drive portion is caught during pivoting back of the coupling members of the control slopes. This leads to an elastic deflection of one of the two spring arms of the actuator. However, the coupling pawl is initially not moved from the coupling position to the release position, since the abutting inclined flanks of coupling projection and coupling recess inhibit pivoting of the coupling pawl. Only when the inner handle or the outer handle has assumed its rest position, the coupling projection can escape from the coupling recess and relax the spring leg of the actuator to pivot the clutch pawl. If the outer handle is actuated in the decoupled position, then the coupling member assigned to the outer bender rotates empty. One of the two coupling members, preferably the outer link associated with the coupling member is held by a spring in a neutral position. In a preferred variant of the invention, it is provided that that of the spring in the neutral position held coupling member also carries the coupling pawl. In this variant, the coupling pawl is spatially associated with the outer link associated coupling member. The held by the spring in a neutral position coupling member can be pivoted both in the clockwise direction, as well as in the counterclockwise direction. As a result, the device according to the invention can be used both on left-hinged, as well as right-hinged doors. But it can also be provided additional blocking members, with which either the pivoting in the clockwise direction or the pivoting can be blocked in the counterclockwise direction. Such a blocking member may restrict the pusher pivotability depending on the installation orientation. The blocking member equally supports the fixed stops of the housing, so that housing made of, for example, plastic in the attacks are not damaged. When the spring is preferably a radially projecting end leg having annular spring, which is partially in an annular channel of the coupling member. The ends of the end legs are based on hard stops of the housing. In addition, a stop extension of the coupling member lies between the end limbs, so that the stop member of the coupling member acts either on one or the other end limb of the spring when the coupling member is rotated in a clockwise or counterclockwise direction. The other end leg of the spring is then supported on the housing. The stop in the housing can also be reinforced by bending a sheet metal lid or by inserting stop pieces, for which, for example, pens are suitable. The coupling pawl is pivotable about an axis of rotation which is substantially perpendicular, but radially offset from the axis of rotation of the coupling members. Between the two, substantially mutually parallel spring legs of the actuator preferably engages an eccentric cam of the electric motor drive. This eccentric cam can be between two stop-limited end positions are pivoted back and forth, wherein the two end positions are preferably slightly more than 180 ° apart, so that the eccentric cam is held in the respective end position in a kind Übertodpunktlage.

The device shown in the figures has a closed housing 4 by a cover, which can be mounted in a attachable to a door fitting plate or in or on a door lock.

The housing 4 has a bearing recess 29 with a circular bearing surface 30. In the approximately cup-shaped bearing recess 29, a coupling member 2 is inserted, the cylindrical extension engages through a circular opening of the bearing surface 30 forming pot bottom. The cylinder extension 24 has a square opening 25 into which the square mandrel of an internal presser can be inserted. The square mandrel, not shown, passes through a nut of a lock, not shown, to retract the lock latch by turning the nut.

The cylinder extension 25 is adjoined by a circular disk-shaped section, wherein the annular surface of the circular disk-shaped section lying on the side of the cylinder extension 24 lies on the bearing surface 30. The face facing away from this surface, lying in the plane of rotation plane 26 points to an end face 27 of a further coupling member 1. In the end face 26 is an eccentric coupling recess 9 with sloping walls 9 '.

The coupling member 1 also has a cylinder extension 20, which is directed away from the cylinder extension 24 and which also has a square opening 19. The square openings 25 and 19 lie in a common axis 3, which is the axis of rotation of the two coupling members 1, 2 ,. The two coupling members 1, 2 are held with a central spacer 34 at a distance.

The coupling member 1 has a radial recess in the form of a slot 23 in which a coupling pawl 5 is pivotally mounted about a pivot axis 8. For supporting the coupling pawl 5, a steel pin may be provided, which is mounted in axle bearing bores 28.

Along a partial section of the circumferential contour of the coupling member 1 extends an annular wall 21 which leaves between itself and the cylinder extension 20 a bow channel 22 for supporting an annular spring 15. In diametrically opposed to the slot 23, the coupling member 1 carries a stop 16. It is a projecting parallel to the rotation axis 3 extension and two stop flanks.

The mounted in the slot 23 clutch pawl 5 has on its side facing the axis of rotation 3 side a coupling projection 6, which is able to enter the coupling recess 9. The two walls facing away from each other 6 'of the coupling projection 6 have a dovetailed bevel, which is adapted to the skew of the walls 9'. The coupling pawl 5 has the shape of a two-armed lever, wherein a first, pointing to the rotation axis 3 lever arm the coupling projection 6 and a second, radially outwardly facing lever arm forms a drive portion in the form of a drive arm 7, which has the shape of a pin with a circular cross-sectional area.

The Fig. 7 and 12 It can be seen that the coupling members 1 in a clockwise or counterclockwise direction by about 30 ° or an angle between 30 ° and 45 ° or an angle> 40 ° from a in the Fig. 4 shown neutral position can be pivoted. To the bearing recess 29 is followed by a curved space 32, in which the coupling portion 5 moves during pivoting of the drive section 7. Opposite the arch space 32, there is another arch space 31, in which an end leg 15 ', or 15 ", of the annular spring 15 can displace upon pivoting of the coupling member 1.

With the annular spring 15, the coupling member 1 is held in a middle neutral position. The spring body of the spring 15 surrounds the cylinder extension 20 and is located in the bow channel 22 a. The two radially projecting end limbs 15 ', 15 "bear against two abutment edges of the abutment 16 pointing away from one another. The outermost end sections of the end limbs 15', 15" lie in the in FIG Fig. 4 shown neutral position beyond also on stop edges 35 of the housing. When the coupling member 1 of the in Fig. 4 As shown in the middle neutral position is rotated clockwise, the end leg 15 "away from the stop edge 35, since it is acted upon by the stopper 16. If the coupling member 1 is pivoted counterclockwise, the end leg 15 'moves away from the stop edge 35, since he then acted upon by the stop 16. The thereby tensioned spring 15 is able to shift the pivoted coupling member 1 back into the neutral position.

In a longitudinal slot 33 of the housing 4, an actuating member 11 which is formed by a hairpin-like bent leaf spring. It form two substantially parallel and spaced apart extending spring legs. The hairpin spring is pivotally mounted about an axis 14 on the housing, wherein the spring legs protrude radially from the axis 14.

Between the two spring legs of the actuator 11, an eccentric cam 17 is arranged, which is located on an output shaft 18 of a drive motor 10. By turning the output shaft 18 of the eccentric cam 17 can be pivoted between two slightly more than 180 ° apart end positions. The eccentric cam 17 is spaced filling between the two legs of the actuator 11, so that the actuator 11 by turning the eccentric cam 17 between the two in the Fig. 5 and 10 shown operating positions can be pivoted back and forth.

The two free ends of the legs of the actuator 11 form actuating portions 12, 13. Between the actuating portions 12, 13, the drive arm 7 of the clutch pawl 5. Is the actuator 11 between the two in the Fig. 5 and 10 pivoted back and forth operating positions, the clutch pawl 5 is between a in the Fig. 5 shown coupling position and one in the Fig. 10 shown release position pivoted back and forth.

At each of the two operating portions 12, 13 close off control sections 12 ', 13', which are formed by oblique flags of the formed by a leaf spring actuator 11 and lie in relation to the drive arm 7 pivoted actuator 11 in the path of movement of the drive arm 7.

• Durch Drehen der Abtriebswelle 18 wird der Exzenternocken 17 zwischen den beiden in den Fig. 5 und 10 dargestellten Betriebsstellungen hin und her geschwenkt. Einhergehend damit kann die Kupplungsklinke 5 von der in Fig. 5 dargestellten Kupplungsstellung in die in Fig. 10 dargestellte Freigabestellung verlagert werden.

The operation of the coupling device is the following:

• By turning the output shaft 18 of the eccentric cam 17 between the two in the Fig. 5 and 10 shown pivoted back and forth. Along with this, the clutch pawl 5 of the in Fig. 5 illustrated coupling position in the in Fig. 10 shown release position to be relocated.

In the in Fig. 5 illustrated coupling position engages the coupling projection 6 in the coupling recess 9, so that the two coupling members 1, 2 rotatably coupled to each other. Will in this operating position either by actuation of an external handle the coupling member 1 or by actuation of an internal presser the coupling member 2 is rotated about the axis of rotation 3, so occurs for example in the Fig. 7 shown operating position in which the drive frame 7 has been removed from the range of the operating portions 12, 13 of the actuator 11. If the operated pusher is released, the coupling member 1 of the tensioned when pressed spring 15 in the neutral, in the Fig. 4 shown shifted position back, in which the drive arm 7 is again between the two operating sections 12, 13.

Was in the in the Fig. 7 shown pivoted position of the eccentric cam actuated so that the actuator 11 is not in Fig. 8 shown, but in the Fig. 13 shown operating position, so the drive arm 7 hits in its return displacement from the in Fig. 7 shown position on a control slope 12 'and slides along it, with the fact that the actuating portion 12 forming the spring leg of the actuator 11 pivots. On the clutch pawl 5 is now exerted by the tensioned leaf spring 11, a torque which is not yet sufficiently large to shift the clutch pawl 5 of the coupling position in the release position, since the inclined walls 6 ', 9' under pressure to each other , Only when this is no longer the case in the middle neutral position, the clutch pawl 5 in the in Fig. 10 pivot shown release position.

Is pivoted in the release position, the coupling member 1, for example, in the counterclockwise direction, as it Fig. 12 shows, the coupling member 2 is not entrained.

In contrast, in the in the Fig. 10 shown release position, the coupling member 2 is rotated, so the coupling pawl 5 carrying coupling member 1 is not drehmitgeschleppt.

Upon rotation of the coupling member 1 in the release position, for example in the in Fig. 12 shown position, the drive motor can pivot the eccentric cam 17, so that actuator 11, the in Fig. 8 represented position occupies. If the coupling member 1 is now pivoted back into the middle neutral position, then the drive arm 7 strikes the control slope 13 'and bends the spring leg of the actuating member 11 which has the actuating portion 13. On the clutch pawl 5 thus a torque is applied. If the coupling member 1 reaches its middle neutral position, that is to say a position in which the coupling projection 6 lies above the coupling recess 9, then the coupling projection 6 can be pivoted into the coupling recess 9 by the tensioned leaf spring of the actuating member 11, so that the in the Fig. 5 shown coupling position is achieved.

Usually, however, the actuator 11 is switched back and forth in the middle neutral position between the release position and the clutch position, so that the drive arm 7 is respectively acted upon directly by the actuating portions 12 or 13.

In the in the FIGS. 14 to 16 illustrated embodiment, the coupling pawl 5 is formed by a spherical drive element 7. However, the drive element 7 can also be designed only as a dome.

The stop 16 has a recess 36, which is helpful in the assembly of the spring 15. At this indentation, an end leg 15 'of the spring 15 can create.

In the embodiment, the spacer 34 is formed only as a disc.

The actuator 11 is formed in two parts in this embodiment. There are two spring legs 12, 13 are provided, each forming an operating portion. The two spring legs 12, 13 are connected to each other by means of a connecting piece 37. The connector 37 has two slots into which the end portions of the leaf spring strips can be inserted. The two slots are parallel and spaced from each other. The connector 37 also forms beyond the axis 14, with which the actuator 11 is mounted on the housing. The bearing recess 39 of the housing 44 serves to receive the connecting piece 37. The bearing recess 39 is closed by a Lagerböckchen 38.

The spring elements 12, 13 have peripheral sliding lugs 40. These are rounded material lugs that slide along the housing wall in the longitudinal slot 33, so as to prevent jamming by sharp-edged punched edges.

The connector 37 as well as the bearing block 38 is made of plastic.

The eccentric 17 is formed in the embodiment as an ellipsoid. At its two opposite curved narrow sides forms the eccentric cam 17 sliding flanks, which are formed by spaced-apart ribs and which can slide on the broad side surfaces of the spring strips 12, 13 along.

The leaf spring 11 may have Gleitfähnchen in the region of its spring legs or in the region of its connecting element, which slide on the housing in the longitudinal slot 33, so as to prevent jamming by sharp-edged punching edges.

In this embodiment, the stop flanks 35 are formed by a blocking stone, which can be used in different orientations in a housing slot 41. In a first orientation, in the Fig. 14 is shown, a blocking cam associated with the stop cam, which forms the two stop flanks 35, is in an operative position. In this position, the coupling member 1 can be rotated in both directions of rotation. If, on the other hand, the blocking block 42 is inserted into the slot 41 in a position rotated by 180 °, then the one which enters into the slot 41 Fig. 14 in its operative position stop cam opposite second stop cam in an operative position. This is adjacent to a blocking arm. In the free space between the blocking arm and the stop cam, one or the other end legs 15 ', 15 "can then be fastened, so that the coupling member 1 can only be rotated in one direction of rotation, and it is then blocked against rotation in the respective other direction of rotation.
