Description

Field of technology

The invention relates to rotating rod locks designed to interact with one another, in particular for pivoting doors of motor vehicle bodies, each with a rotating rod and a locking lever, the locking lever having a handle part or being articulated to a handle part and a base body, the locking lever also having a pawl spring-loaded into a locking position having, wherein after a rotation of both rotating rod locks into their open position, mutual locking of the locking levers is enabled, the locking lever also having a free end as seen from the rotating rod beyond the pawl.

State of the art

Espagnolette locks of the type in question are known, for example from DE 19902249 B4 . Such a rotating rod lock is used to lock a pivoting door of a motor vehicle body, such a structure preferably having two pivoting doors that can be pivoted open in opposite directions, with each pivoting door being able to be assigned at least one rotating rod lock, further for example two rotating rod locks. Such an espagnolette lock can interact with a base plate of the motor vehicle body and / or a frame element of the same, in particular with regard to the pawl.

There is a need to lock the pivoting doors pivoted into an open position against one another so that they remain in an open position. In this open position, the swing doors can with reference to a cross-section in which the geometric pivot axis of a pivot door is represented as a point, each enclose an acute angle of preferably less than 45 degrees, for example 10 or 15 degrees, to an alignment of the respective pivot door in the closed position. This open position secured by the espagnolette locks can be used, for example, to ventilate the motor vehicle body and / or during maneuvering work with the motor vehicle body.

In this secured open position of the swing doors, the espagnolette locks are mutually locked. In this regard, solutions are known in which the free end of one locking lever is used to latch onto the locking lever of the other pivoting door. The latching can be provided here by a grip behind, for example as a result of the free end of the one locking lever of the one pivoting door reaching behind a section of the other locking lever of the other pivoting door.

From the EP 2623695 A1 An espagnolette lock for pivoting doors of motor vehicle bodies is known, in which a latching between a handle part of the locking lever and a base body of the locking lever is possible in order to achieve a secured open position. A comparable prior art is also from EP 2711489 A1 and the DE 202009004481 U1 known.

Summary of the invention

Based on a prior art, for example according to FIG EP 2623695 A1 The invention addresses the problem of specifying an interaction of espagnolette locks formed with one another on pivoting doors of motor vehicles, which allow an advantageous open position.

This object is achieved in the subject matter of claim 1, the aim being that the one locking lever forms a locking receptacle through the locking pawl and a locking lever fixed locking opening, and that the other locking lever has two matching locking formations at its free end.

In an advantageous manner, locking of the espagnolette locks against one another for locking the pivoting doors in an open position can be achieved using and integrating at least one of the pawls of the espagnolette locks. The latching can be achieved using latching formations of one espagnolette lock formed at the end of the locking lever on the one hand and using a latching receptacle receiving the latching formations on the locking lever of the other espagnolette closure on the other hand. For this purpose, a locking formation of one locking lever can engage in the locking opening of the other locking lever, while the further locking formation of one locking lever can interact with the locking projection of the pawl of the other locking lever which is provided in the usual way.

The latching or locking position of the espagnolette locks against each other can, as is also preferred, only be canceled deliberately, namely by a conventional pawl release, which is also carried out for unlocking the espagnolette lock in the pivoting door locking position. In this way, even with this mutual latching of the espagnolette locks, the user has a customary handling for canceling this latching.

In addition, this embodiment ensures that the locking position of the espagnolette locks against each other can only be canceled deliberately as a result of a corresponding triggering.

According to a conventional locking pawl arrangement, the locking projection or the like of the locking pawl can also be overrun by the associated locking formation of the one locking lever in the course of finding the locking position for locking the espagnolette locks against each other, in that the locking pawl is deflected against the spring preload by the locking formation.

According to the proposed embodiment, there is an easy-to-use locking of the rotating rod locks against one another. Also, as preferred, a secure latching can be provided, which prevents uncontrolled pivoting of one or both of the pivoting doors in the direction of an extended open position and / or in the direction of a pivoting door closed position when the motor vehicle body is being transported in this pivoting door open position.

According to one possible embodiment, both the latching receptacle and the latching formations can be formed on both locking levers. This can result in the advantageous effect that the mutual locking of the espagnolette locks in the hinged door open position can optionally take place by attaching a first espagnolette lock to a second espagnolette lock or the second espagnolette lock to the first espagnolette lock. This also results in an effect that is advantageous in terms of production technology, since the espagnolette locks can be of the same design, in particular with regard to the design of the locking levers.

A latching formation can be formed in relation to a cross section in which the geometric axis of rotation of the pivoting door or the rotating rod of the rotating rod lock is represented as a point, as an outwardly protruding bay formation relative to the outer contour of the adjoining locking lever area, preferably adjoining on both sides. This corresponding elevation with respect to the surrounding locking lever area is preferably captured in the locking position by the locking receptacle, further preferably by the locking pawl or the locking opening fixed to the locking lever.

With reference to the above-described cross section, the oriel formation can be formed in a corner area of the locking lever, and furthermore, if necessary, emboss this corner area.

Furthermore, a latching formation can be formed on the main body of the locking lever and thus fixed relative to the locking lever, and the further latching formation on the handle part articulated to the main body of the locking lever. In an alternative embodiment, both latching formations can also be formed on the base body and thus preferably rigidly on the locking lever.

Description of the embodiments

Is shown and described, initially with reference to Figure 1 , a motor vehicle body 1. The enclosed cargo space is accessible via two pivoting doors 2 and 3, which are hinged in the manner of a double wing door.

The two pivoting doors 2 and 3 are hinged in the transition area to the longitudinal walls of the motor vehicle body 1. Several hinges 4 are provided, for example four hinges 4 assigned to each pivoting door 2 or 3.

Rotating rod locks 5 are used to close and open the pivoting doors 2 and 3. A component of each rotating rod lock 5 is a rotating rod 6 protruding vertically through the leaf or wing of the associated pivoting door 2 and 3. This rotating rod 6 goes into the area of the ceiling 7 of the motor vehicle body 1 a twist lock 9 over. This is connected to the rotating rod 6 in a rotationally fixed manner and engages in a receiving pocket 9 in the area of the ceiling 7 in a locking manner.

The rotary actuation of the rotary rod 6 is achieved via a locking lever 10. This is preferably located below a loading floor, not shown in detail, of the motor vehicle body 1 at the lower end of the associated rotating rod 6 and can, in the locked state, according to the illustrations in Figures 1 to 3 and 7 be locked in a base plate 11.

The base plate 11, viewed from the outside A of the door, can be arranged and fastened on the rear side of a frame element 12 of the motor vehicle body 1, which frame element 12 is a frame girder or can form a cross member underneath the loading floor (compare in particular Figure 1 ).

The base plate 11 and / or the frame element 12 can have through openings 13 and 14, in particular for a centering pin 15 and a cantilevered locking extension 16 of the locking lever 10.

Viewed in the direction of longitudinal extent of the base plate 10, opposite to an edge edge associated with the bolt extension 16 in the closed position, the edge edge formed there is designed as a counter catch 19 for a pawl 20.

Associated with the reach-through opening 13, a bead-like abutment formation 21 can be formed for interaction with the locking extension 16 of the locking lever 10.

The locking lever 10 is essentially composed of a base body 22 and a handle part 23. The base body 22 and handle part 23 can be used according to the example shown in FIG Figures 7 to 10 illustrated second embodiment in one piece and possibly made of the same material, in any case rigidly connected to one another.

The one in the Figures 1 to 6 In contrast, the first exemplary embodiment shown, the handle part 23 is supported on the base body 22 such that it can pivot.

The base body 22 is also connected to the rotating rod 6 in a rotationally fixed manner. Their geometric axis of rotation x extends perpendicular to a longitudinal extension of the locking lever 10. This longitudinal extension of the locking lever 10 is at least in the blocking position of the espagnolette lock 5 in a transverse direction to the pivot axis y of the pivoting doors 2 and 3 and thus in the usual use position at least approximately in the horizontal direction.

The rotating rod 6 is arranged in an end area with respect to the longitudinal extension of the locking lever 10 or the base body 22. Further associated with this end region, the cantilevered bolt extension 16 is rigidly connected to the base body 22 in the direction of the pivoting door 2 or 3, respectively. This runs according to the sectional view in Figure 3 with its edge edge facing the base plate in the blocking position of the contact formation 21 following approximately along a circular line.

The aforementioned centering mandrel 15 is also integrally formed on the base body 22. This centering mandrel 15 is approximately frustoconical and suitable for engaging in the reach-through opening 14 of the base plate 11.

The pawl 20 is also rotatably supported in the base body 22 about a pin 24. The related geometric axis of rotation z runs in the same direction as the axis of rotation x of the rotating rod 6.

The pawl 20 has a lever arm 25 for moving the pawl 20 from a locked position into an open position, and a pawl extension 26, which is in the locked position according to FIG Figure 3 or 7 can catch behind the edge of the counter-catch 19 provided on the base plate 11 like a hook.

In the direction of this blocking position, the pawl 20 is loaded by a spring 27, here for example by a torsion spring.

The direction of rotation c of the locking pawl 20 for moving the same from the locking position into the open position can be aligned with the direction of rotation d of the entire locking lever 10 for moving the espagnolette lock 5 from the locking position into the open position. Alternatively, the direction of rotation c can also be selected to be opposite to the direction of rotation d.

The handle part 23 of the first embodiment according to FIGS Figures 1 to 6 is held in an articulated manner on the base body 22. The pivot joint 28 in this regard, viewed from the pawl 20, is formed at an end of the locking lever 10 or of the base body 22 which is opposite with respect to the pivot rod 7 or the bolt extension 16. The geometric axis of rotation of this swivel joint 28 runs in the same direction as the axis of rotation x of the rotating rod 6 or the axis of rotation z of the pawl 20.

In the end area of the handle part 23 of the first embodiment facing the pawl 20, the handle part 23 carries a peg-shaped entrainment extension 29. This engages through a slot-like opening 30 in the illustrated embodiment into the interior of the base body 22 and here comes against the lever arm 25 of the pawl 20 ( compare for example Figures 3 and 4 ).

To unlock the espagnolette lock 5, a pivoting displacement of the pawl 20 into a position releasing the grip behind the counter-detent 19 is necessary.

In the first exemplary embodiment, this is achieved in a technically simple manner by pulling the handle part 23, which leads to a pivoting displacement of the handle part 23 about the swivel joint 28. The direction of rotation f of the handle part 23 is directed opposite to the directions of rotation c and d of the pawl 20 and the locking lever 10 as a whole. As a result, a displacement of the driving extension 29 in the slot-like opening 30 is achieved, via which driving extension 29, while resting on the lever arm 25, the locking pawl 20 according to the illustration in FIG Figure 4 is shifted into a position releasing the counter-detent 19. This pivoting displacement of the pawl 20 takes place against the force of the spring 27.

When the pawl lock is released, both the pawl 20 and the base body 22 are preferably pulled along via the handle part 23 in the direction of an open position by limiting the displacement of the driving extension 29 in the opening 30. Here, the centering pin 15 also emerges from the associated reach-through opening 14. The bolt extension 16 pivots out of the associated reach-through opening 13 of the base plate 11.

In an alternative embodiment according to the illustrations in Figures 7 to 10 the handle part 23 can be rigidly connected to the base body 22. Correspondingly, the axis of rotation x of the rotating rod 6 is at the same time the axis of rotation of the handle part 23 with the base body 22.

In this embodiment too, the pawl 20 is held pivotably on the base body 22 via a pin 24. A spring, not shown, loads the pawl 20 in the direction of the locking position.

The lever arm 25 of the pawl 20 is ergonomically located in the area of the handle part 23, in particular forming a partial area of the handle part 23. For this purpose, the handle part 23 can have a recess, for example a slot-shaped recess, that can be penetrated by the lever arm 25 of the pawl 20. In this, the leg of the lever arm 25 can preferably lie freely in the blocking position.

The unlocking of the espagnolette lock 5 formed in this way also takes place here in a manner that is advantageous in terms of handling. Just by grasping the handle part 23 in the usual way, the lever arm 25 of the pawl 20 is also encompassed at the same time. A conventional pulling movement to initiate the pivoting of the area 23 and above this of the entire locking lever 10 causes a corresponding pivoting displacement of the pawl 20 in the direction of the release position.

If, in the solution according to the first embodiment, the direction of rotation c of the pawl 20 in the course of unlocking is opposite to the pivoting movement s of the handle part 23, in the embodiment according to FIGS Figures 6 to 10 the directions of rotation of pawl 20 and handle part 23 are in the same direction.

As further also from Figure 1 As can be seen, the locking levers 11 are freely accessible below the pivoting doors 2 and 3, so that after the locking and pivoting of the locking lever 10 into the position releasing the associated pivoting door 2 or 3, the locking levers 10 are essentially free around the geometric axis of rotation x of the rotating rod 6 can pivot. This can be used to secure the pivoting doors 2 and 3 against each other using the locking levers 10 facing away from the hinges 4 and to lock them in place around the pivoting doors 2 and to hold 3 in a position that is not fully swung open (cf. Figures 5 and 9 ).

For this purpose, according to the representations, the hinge-remote locking lever 10, which is assigned to the pivoting door 2 and is assigned to the left in the representations, can be pivoted back in an opposite direction of rotation d 'after its pivoting movement to unlock the pivoting door 2 in the direction of rotation d, preferably into a position which is via the parallel position of the locking lever 10 to the frame element 12 in the closed position according to Figure 3 so that, in relation to this alignment of the locking lever 10, the locking lever can be pivoted in the direction of rotation d 'by an angle of about 30 to 60 degrees, further about 45 degrees.

The hinge-remote locking lever 10 assigned to the pivoting door 3 in the exemplary embodiments is pivoted further in the pivoting door release position in its release direction of rotation d, compared to the parallel alignment in the locked state according to FIG Figure 3 about 150 to 210 degrees, further for example about 170 to 190 degrees, possibly about 180 degrees, so that correspondingly the pawl 20 and the centering pin 15 are directed outwards, pointing away from the motor vehicle body 1.

In this alignment of the locking levers 10, they can be locked to one another to secure the pivoting position of the pivoting doors 2 and 3.

Here, both the locking lever 10 of the pivoting door 2 can be latched to the locking lever 10 of the pivoting door 3, as can alternatively, as also shown, the locking lever 10 of the pivoting door 3 to the locking lever 10 of the pivoting door 2. Correspondingly, both locking levers 10 be designed the same in particular with regard to the training required to achieve these locking positions.

Each locking lever has latching formations 32 and 33 on its free end 31, which is formed on the other side of the pawl 20, as seen from the rotating rod 6. These can, as also shown, with reference to a cross section in which the axis of rotation x of the rotating rod 6 is represented as a point, be formed in corner areas of this free end 31, with at least one of the locking formations 32 on the base body 22 and thus essentially stationary can be formed on the locking lever 10. In particular, this latching formation 32 is represented as an outwardly protruding oriel formation 34 which essentially defines the above-described corner area of the base body 22.

On both sides of the oriel formation 34, on the one hand associated with a longitudinal extension side of the base body 22 and on the other hand associated with a narrow side of the base body 22, there are locking lever areas 35 which spring back like a groove in relation to the adjacent areas of the base body 22. As a result, the bay formation 34 is exposed.

The further latching formation 33 opposite this latching formation 32 at the end can optionally be flanked solely on the longitudinal edge side by a groove-like locking lever area 35, for example, as also shown, due to a notch-like depression opposite the surrounding lateral surface of the base body 22 (compare in particular the illustrations in FIG Figures 6 and 10 ).

The further latching formation 33 can be formed at the end of the handle part 23 which is pivotably articulated on the base body 22.

In the illustrated embodiment according to the Figures 7 to 10 Both locking formations 32 and 33 are rigidly formed on the base body 22.

In the mutual latching position, the latching formation 33 preferably works together with the pawl extension 26 of the pawl 20. The pawl extension 26 overlaps the latching formation 33 and, if necessary, dips partially into the lowered locking lever area 35.

When the free end 31 of one locking lever 10 is attached to the pawl 20 of the one locking lever 10, the detent formation 33 can be overrun and captured by the pawl extension 26 by automatically evading the pawl 20 against the force of the spring 27.

The attachment in this regard takes place as a result of receiving the bay-like latching formation 32 in a latching opening 36 on the locking lever side. This latching opening 36 is preferably formed on the base body 22, further in particular in an area between the pawl 20 and the centering pin 15.

The latching opening 36 forms a latching receptacle 37 together with the pawl 20.

To lock the locking levers 10 against one another, the free end 31 of the one locking lever 10 can be attached in such a way that its latching formation 32 is received in the latching opening 36. By correspondingly pivoting the free end 31 in the direction of the pawl 20 of the other locking lever 10, the further latching formation 33 is overrun and captured by the pawl 20.

This essentially results in an approximately 180 degree encirclement of the free end 31 of the one locking lever 10 by the latching receptacle 37 of the other locking lever 10.

This enclosure can preferably only be canceled as a result of deliberate intervention, in particular as a result of triggering via the pawl 20 in accordance with the above-described cancellation of the locking of the pivoting doors 2 and 3 on the motor vehicle body 1.

So the mutual locking of the locking levers 10 is in the Figures 1 to 6 illustrated first embodiment by a pivoting displacement of the handle part 23 in the direction of rotation f of the locking lever 10, the pawl 20 of the latching formation 33 of the other locking lever 10, can be reached. As a result of this displacement of the handle part, the pawl 20 is dragged into its release position, with the corresponding removal of the enclosure of the free end 31 of the other locking lever 10.

A comparable triggering also results in the second exemplary embodiment according to FIG Figures 7 to 10 . Here, too, the pawl 20 is shifted into its position releasing the enclosure (direction of rotation c) while gripping the handle part 23, after which the locking levers 10 are unlocked from one another and the pivoting doors 2 and 3 are pivoted further into their (fully) open position or back into the closed position can.

The above-described locking of the locking levers 10 against one another to enable a secured open position of the pivoting doors 2 and 3 is also possible with designs known from the prior art, in which the locking levers 10 for locking the pivoting doors 2 and 3 in their locked position with an outside of the frame element 12 arranged Baseplate 11 interact or directly with the frame element 12. <b> List of reference signs </b> 1 Motor vehicle body 27 feather 2 Swing door 28 Swivel joint 3rd Swing door 29 Take-away extension 4th hinge 30th opening 5 Espagnolette lock 31 free end 6th Rotating bar 32 Locking formation 7th blanket 33 Locking formation 8th Quarter-Turn 34 Oriel formation 9 Receiving pocket 35 Locking lever area 10 Locking lever 36 Locking opening 11 Base plate 37 Snap recording 12th Frame element 13th Reach-through opening c Direction of rotation 14th Reach-through opening d Direction of rotation 15th Centering pin d ' Direction of rotation 16 Latch process f Direction of rotation 17th Breakthrough x Axis of rotation 18th Breakthrough y Axis of rotation 19th Counter-rest z Axis of rotation 20th Pawl 21 System design A.
