Background Art

Lock the opening states with the locking device, the locking device comprises a rotating lock fork and the at least one locking claw, with the aid of the locking claw can the rotating lock in locked in the locking position. Rotation of the locking position can be maintained in lock or hatch lives in the gate the stopper so as to allow the door or hatch cover can not be opened. If the turning lock fork is located in an open position, the retaining block can leave the locking device and the door or hatch cover can be opened.

Literature DE   10   2010   003   483   A1 discloses a kind of locking device, wherein if the locking claws main locking position is locked in the lock, the rotation of the lock into the locking claw in the opening moment. Rotating the window can be based on, for example, door sealing member based on pressure and/or preload is applied to the spring and/or through the corresponding opening of the door or hatch into the this kind of running torque in the locking claws, the spring can enable the rotating lock fork to rotate to its open position. By opening the moment can make the locking jaw away from its locking position. In order to under the condition of the locking device is locked reliably avoid such a situation, additional to a locking rod, the locking rod capable of preventing locking jaw away from its locking position. In order to open this kind of locking device, the locking rod by means of a release lever to swing from its locking position. Generally, through the rotation of the locking claws is introduced into this opening torque is sufficient to unlock the locking device, that is to say open the locking device.

Opening the lock of this kind mainly comprises a release lever, the release lever can be by means of the locking of the locking device is opened, that is to say is unlocked. Caused by actuating the release lever: locking claw in order to open the locking device and to leave or to leave its locking position.

With the opening moment of the locking device, may be due to various reasons, the following conditions: open the torque is not sufficient to make the locking claw swing from the locked position. In order to nevertheless still ensure that the locking device even in this kind of error cases also open, is provided with a takes along the moving parts , the carrying moving part such as the installation of the release lever and/or if in DE   10   2010   003   483   A1 in the ground mounted in the known pre-locked-locking claw. Particularly in the torque can not only on the basis of the opening of the locking jaw away from the locking position, this carrying member will swing the locking claws from its locking position.

In order to make the locking claw can be based on takes along the moving parts is opened, for example, is set in on the release lever takes along the moving parts must be able to swing sufficiently large angle. Usually 20° to 30 °, for example about 25° is enough to only on the basis of the angle of the locking claws takes along the moving parts and totally leave its locking position.

Usually by operating the handle to swing the release lever of the locking device. The handle may is the handle in the door of the motor vehicle or outside door handle. This handle general through the guard bar or bao ascends the back guy is connected with the release lever, by operating the handle to make the release lever to swing. The guide rod or bao ascends the back guy wear phenomena and/or tolerance will be actuated through the handle swing angle of the release lever is reduced or said drop.

Content of the invention

The invention the technical problem to be solved is to: provide a reliable operation of the the above-mentioned type of the lock.

The technical problem of the present invention by having the characteristic of the claim 1st of the flask. A favourable design scheme is requested from the right.

In order to solve this technical problem and provides a cover for the door or lock, the lock has a locking device, the locking device comprises a rotating lock fork and at least one is used for locking the rotation of the locking fingers lock. The rotating lock fork and the locking claw can be configured such that the rotation of the torque lock, in particular in opening the moment introduced into the locking claws. In one embodiment, by rotating the lock fork even if the locking device in the locking position of the closing torque can also be introduced in the locking claws, so that even in case of locks the dead stick is not arranged can also be a particularly reliable locking. In is as follows under the condition of the closing torque of the force of the in is introduced into the locking claws: the force to the locking claws in the direction toward a locking position. In no a locking device under the condition of locks the dead stick can be very reliably locking. However, in this case the device requires a relatively greatly, in order to make the locking jaw away from its locking position, so as to open the locking device. strength also due to the exertion of the rotating lock fork and the locking claw caused by the frictional resistance between, the rotating lock fork and the locking claws, the greater the frictional resistance between the, the consumption of the greater force. For example, the pollutant may be frictional resistance, such as sand and increase the.

According to the invention, into the locking claw of the locking of the locking claws torque and position-related, that is to say with the anti-rotation lock fork is returned to the opening position of the position-related locking claws. That is to say, there are at least two different, in particular the running torque of the different sizes, the torque can be with associated locking position of the locking claws by the rotation of the lock in the locking claws. Through claim 1 according to the theme of the moment can be introduced in the locking claws. For is introduced into the locking claws the needs of the running torque in the locking position normally associated with the corresponding. Through this way can provide a particularly reliable locking of work.

In the present invention in one embodiment of, first of all, inter alia, the existence of a locking claw is completely located in the locking position by rotating the lock in the locking claws in the opening moment. The locking device in order to close a door or hatch cover required to be locked, the locking claw is completely located in its locking position. Proceeding from the latched position, the locking claw can be in particular the complete does not cross the locking position or only very small (overrunning) to more than the full locking position, this is because of for example by a stop portion preventing the locking claw beyond the locking position. And if the locking claw partially leave the locking position, the torque change. At this moment or more large opening torque, or the initial presence of the opening moment. When the locking device is opened, the first locking claw to leave its full locking position. Therefore, in particular from an open torque a will ultimately a greater torque is introduced into the opening in the locking claws, so that opening more easily.

In the present invention in one embodiment, is provided with at least two large and small different opening moment, the two opened by the rotating moment can be introduced into the lock in the locking claws. If locking claw totally located in its locking position, first, the rotating lock of a relatively small torque is introduced into the 1st in the locking claws. If locking claw has been partially, but not completely leave its locking position, the lock by the rotation of a larger open 2nd in torque into the locking claws. In this embodiment a, on the basis of the greater torque, even when used for a of the locking claws due to various reasons takes along the moving parts no longer swing far enough in order to make the locking claw completely leave their locking position, and the locking claw can be also left its locking position. In this embodiment there are also locking bar, the locking claw the locks the dead stick totally located in its locking position, in particular the main locking position can be locked or when locking the locking claw.

In one embodiment, the release lever 15° to the swing angle of the locking device can ensure the reliable unlocking. Preferably, for this swing angle is 13° is sufficient.

Furthermore, in one embodiment the lock includes a release lever, the release lever with the aid of the movement of the release lever, in particular the swing of the release lever to the lock of the locking device to unlock. If the release lever in order to open the locking device for the purpose of swing, by the rotation of the first lock is in 1st torque into the locking claws. If the release lever is not in the most likely way of the swing, the end opening torque is introduced into a 2nd in the locking claws, the 2nd 1st open the torque larger than the torque. Preferably, the release lever in the movement of the swinging movement of the its preset more than 70%, preferably more than 50% before, the torque from the rotation of the 2nd into the lock in the locking claws. If constructed in this way, for example, release lever, the release lever to swing in order to open the locking device 25 °, then the oscillating locking claws on the evening of 17.5 °, that is to say to 70% of the, the 2nd will be greater in the torque introduced into the locking claws. Preferably, the release lever to swing the 12.5 ° before, that is to say also in achieving 50% before, the 2nd will be greater in the torque introduced into the locking claws. Through this embodiment the opening of the locking device for the buffer. If the release lever for example because of aging (wear, tolerance) and no longer can swing over the whole distance, then the 2nd through greater torque to ensure that the: place, even if the release can also swing to the 70% or 50% under the condition of the locking device can also be reliably opened.

In the aforesaid embodiment in particular to a takes along the moving parts , the carrying member can make the locking jaw away from its locking position. In particular, based on only the opening moment is not introduced into the locking jaw away from its locking position, the carrying member so as to enable the locking claw at least partially away from its locking position. takes along the moving parts ensure that the through, into torque 1st on the basis of the opening mechanism is invalid, at least at the beginning of the locking claws by the carrying member from its locking position. If the carrying part of the follower the locking claws to leave its locking position, the end into the opening moment greater in the locking claws. The greater the opening moment is preferably large, even if the locking claw at this moment under the support of the not takes along the moving parts can also leave its locking position. Thereby realizing the: even when the release lever due to various reasons no longer swing over the whole distance, the locking device can also be reliably opened. Even if the release lever can swing over the whole distance, through the embodiment also realizes: the takes along the moving parts where necessary the locking claw part shall be only to leave its locking position will be able to open the locking device. For opening the locking device is also raised in case of trouble in this kind is advantageously reduced.

In order to be able to further improving the compactness of the having a small number of parts of the form structure, in one embodiment the locking device, of which the locking claw and the release lever in a manner to be able to rotate is supported on a common shaft.

Advantageously, through a spring in the direction of the opening position of the faces the lock the rotating lock preload is applied, the sealing pressure of the door in order to in the absence of torque can also be introduced in the locking claws.

In the present invention in one embodiment of, the release rod can make the locking device from its locking position of the locking rod. Therefore, in principle, relatively small, it is sufficient to the device. If because of rotating immediately introduced into the lock in the locking claws and the opening moment of the locking jaw away from its locking position, locking device is opened the necessary device advantageously very small on the whole.

In one embodiment, is used for the locking rod is moved to its locking position of the spring. In a simple and reliable by the spring means so that it can make the locking rod is moved to its locked position. In one embodiment, a locking claw structure and locks the dead stick : by making the locking lever is moved to its locking position by the locking claws at the same time is moved to its locking position. The number of parts required by this is further minimized. This accompanied by weight and reduce space structure.

In one embodiment, the release lever includes three lever arm. The 1st lever arm in particular by means of locking lever away from its locked position in order to unlock the locking device. 2nd lever arm by means of the release lever in the manner preferably to the locking claws for unloading, that is to say the locking device can be is open at least toward a locking position of the locking claws in the direction of the spring force of the movement of. Preferably, the 2nd lever arm also advantageously includes used for the locking claws takes along the moving parts leave their locking position, in order to be able to compact and simple to produce. 3rd lever arm by means of the release lever is actuated, for example, with the aid of the guide rod or bao ascends the back guy and which is connected with the preferably by means of the handle or the electric driving device is actuated. If the handle is operated or electric drive running of the device, is therefore 3rd lever arm also is actuated and release movement in order to unlock the locking device, in particular the swing around the axle. Especially for structure the purpose of minimizing space and weight, advantageously also the 2nd lever arm is provided with a retaining part, in order to prevent the release lever over the desired end position.

Preferably, the locking claw includes two the lever arm. By means of a lever arm locking the rotating lock fork. A mechanism, such as preload is applied to the spring action of a lever arm to the other, in order to by means of the mechanism, that is to say that for example the spring preload is applied to the locking claw can be moved to its locking position. Alternatively in order to unlock the locking device for release of the locking claws of the seize takes along the moving parts a lever arm and the other corresponding to the movement, in particular to be swung around the axle. Advantageously also is used for the other the stopping part of a lever arm, in order to prevent the locking claw across its full locking position.

For the locking jaws in locked in its locking position the lock of the lever preferably comprises two lever arm. locks the dead stick 1st lever arm in particular of the locking claw can be locked in its locking position and/or the locking claw is moved to its locking position. Especially advantageously in one embodiment, the release lever can also be composed of the 1st lever arm and the movement, in particular the swing around the axle in order to leave their locking position. The locks the dead stick 2nd lever arm may preferably be on the movement to a stop, in order to make the locking lever cannot be crossed the predetermined end position. 2nd lever arm is also advantageously help to: the center of gravity of the locking lever towards the locking rod can oscillate around the same is shifted in the direction of the shaft. This kind of the center of gravity to shift and cause the locking rod is easier to swing.

In one embodiment for minimizing part (quantity) of the locking rod the purpose of release lever can be formed at the same time. In one embodiment the release lever at the same time it is also pre-locked-locking claw, the locking fork can make the rotating in pre-lock position. The locking device can subsequently be closed the door or hatch cover. In accordance with the plan has not been, however, in the locking position. The rotating lock fork to swing in the direction of towards the closed position, from a prelocking position to the main locking position.

Locking device according to the invention usually in particular to a lock plate that is made of metal, or usually made of metal on the lock. Usually the lock also comprises a lock housing, the lock housing is made of plastic and is usually obstructs the cover lock part of the can. In addition can be arranged in particular is made of a plastic and/or lock is made of a plastic, in particular for the central locking device of the cover, the cover for covering the same. Lock can, for example, belongs to the building door or hatch cover or belongs to the motor vehicle door or hatch cover.

The invention also includes lock as follows: the lock for rotation of the main locking position of the locking claw (also referred to as "the main lock-locking claw"), is used for rotating the fork opening of the locking claw pre-lock fixed position (also referred to as "pre-locking-locking claw") and advantageously also is used for the main locking-locking claw of the locking rod. In the literature this kind of lock DE   10   2008   061   524   A1 to open. According to the invention can in addition also locks butlocks the dead stick also include only one locking claw, the locking claw and is used for the rotating lock fork is locked in the "pre-locking" position and "the main lock" position.

Rotation of the lock into the slot with a forked (inlet), the door or hatch is closed or hatch cover and the variations of the access slot in the block. Subsequently, the rotating lock the block from the open position to rotate to the locked position. In the latched position is no longer be able to leave the block of rotation into the slot. Locking claw the rotating lock in locked in the lock-in position, so that the rotation lock fork is no longer capable of returning to an open position.

The lock according to the present invention is arranged in the part of the can and should swing, such as a locking claw, lock locks the dead stick or rotate. Usually provided with at least one preload is applied to the spring, in particular of the spiral torsion spring, through the spring force of the spring is realized by means of this kind of part of the swinging movement of the desired. The preload is applied to the spring can be for example of the locking claw is moved to its locking position, the locking lever is moved to its locked position, or so as to enable the rotation lock fork is moved to its open position.

Mode of execution

In fig. 1 shows the construction of a locking device, which comprises a rotating lock fork 1, the locking claw 2, locks the dead stick 3 and the release lever 4. The rotating lock 1 can be around its shaft 5 swing. Locking claw 2 and the release lever 4 around the common shaft can be 6 swing. locks the dead stick 3 can be around its shaft 7 swing.

In fig. 1 shown in the beginning of the opening process. Through the release lever 4 has been along the counterclockwise swing of the locks the dead stick 3 leave their locking position. Locking claw 2 still use its lever arm 8 locking the rotating lock fork 1. Will turn on the torque introduced into the locking claw 2 fork of rotation of 1 therefore used for: the locking claw 2 the pendulum leaves the locking position shown, particularly in Figure 1 is the situation around the shaft 6 swings along the counter-clockwise direction. If the mechanism fails, then, ultimately, through the release lever 4 to continue the swing of the along the counter-clockwise direction, and make the takes along the moving parts 9 in the side contact locking claw 2 of the lever arm 11 and the lever arm to swing counter-clockwise direction then along the same, the portable part 9 from the release lever 4 of the lever arm 10 extending upwards. Through this kind of additional mechanism, if initially not can be made by a large enough torque into the locking claw 2 to realize the left, the lever arm 8 in case of emergency can be at least partially away from its locking position. If such as dust or wear so that the unlocking is obstructed or difficult, the carrying member 9 can be used as the locking claw 2 with the rotating lock 1 the additional unlocking member between.

The locking claw is in its Figure 1 is shown in a locking position, any time in order to open the moment can be introduced into the locking claw 2 in, the preload is applied to the spiral torsion spring by means of the in Figure 1, it can be seen that the spring arm 14 will rotate lock fork 1 the direction of the pressure to the open position. Based on the spring by means of the spring arm 14 can make the rotating lock fork in fig. 1 along the counter clockwise direction under the condition of the direction toward the open position around the shaft 5 to rotate.

In order to actuate the release lever 4, that is to say in order to in Figure 1 under the condition of the release lever to swing counter-clockwise direction, will be in an appropriate manner the manipulation of the handle is transmitted to the release lever 4 of the pole 15, for example, with the aid of bao ascends the back guy , rod or guide rod to transmit.

The stopping part 16 of the release lever 4 of the lever arm 10 or locking claw 2 of the lever arm 11 along a clockwise direction for limiting the swinging movement of the. The release lever 4 and the locking claw 2 therefore cannot pass a corresponding set of the end position. Therefore, the locking claw 2 can be always moved to its locking position, but will not cross over the locking position. The release lever 4 to swing along the clockwise direction is also limited in a suitable way, so that the handle a relatively short operating stroke is sufficient to unlock or open the locking device. The stopping part 17 on the one hand for holding the spiral torsion spring the spring leg 18, the spiral torsion spring can make locks the dead stick 3 along the counterclockwise swing to its locking position. The stopping part 17 limiting locks the dead stick 3 along the counterclockwise swing, thus locks the dead stick 3 not can cross its locking position. In particular the release lever 3 of the lever arm 25 to limit the swing of the. The stopping part 19 for holding a spring arm 14 and optionally as a rotating lock fork 1 stopping part, in order to lock the rotation of the appropriate 1 along the clockwise direction of rotation motion, thus limiting rotary lock fork 1 of the over travel.

In fig. 2 according to the shown in Figure 1 the back of the locking device. In this we can see that the pin 20, the pin towards the release lever 3 locked by lever arm 21 projecting in the direction of and is used as the locking arm 21 takes along the moving parts of. If the release lever 4 is actuated, the lever arm 22 eventually seize the corresponding projecting pin 20 and enable the swing, therefore also make locks the dead stick 3 such swing, so that the locking lever away from its locking position.

In the Figure 1 and 2 as shown in a set can be selected, preferably made of plastic for the retaining block of the 27 enter the buffer 26, in order to avoid noise squeek loud snapping sound. The rotating lock fork on the plastic jacket for the subregion of the transducer 28 in the block 27 is opened. The rotating lock fork can include the protruding pin 29, the locking device including a bit in Figure 1 the locking fingers as shown in 2 above the-pre-locked in the level of the locking claws, the protrusion of the pin can be used for the locking device locked in the pre-lock position.

Figure 3 shows the rotating lock fork 1, locks the dead stick 3 of the lever arm 21 and the locking claw 2 of the lever arm 8 in amplification main locking position of the local map. Because of the lever arm 21 locking the locking claw 2 of the lever arm 8, thus locking claw 2 is in its fully locked position. The rotating lock fork 1 leans against the locking claw 2 of the lever arm 8 forming part of the side surface of one section 30 on. The radius of the forming part of the 1st R1 in particular to 18-22mm, preferably 20 mm. The rotating lock 1 in the shaping section 1st 30 is on, the rotating lock 1 into the 1st open torque M locking claw 2 in. If locks the dead stick 3 leave their locking position, the locking claw 2 main locking to leave the first position thereof. The rotating lock fork 1 eventually bears against the locking claw 2 of the lever arm 8 of the shaping section 2nd 31 on. 2nd forming section 31 of the radius R2 is relatively small and in particular less than 20 mm. If the turning lock the fork pastes against the 2nd forming section 31 is, then, still through the locking claw 2 avoid the rotation lock fork 1 swing to return to the open position. But now by rotating the lock fork 1 will increase the opening torque M into the locking claw 2 in. The forming section 31 after 3rd the shaping section 32, the 3rd the bending degree of shaping section significantly more strongly. 3rd shaping section 32 no longer able to avoid the rotation lock fork 1 moves to the opening position. Shaping section 30 and 31 in the position of the release lever 4 coordinated the swinging movement of the. If the release lever 4 to swing the 50% and/or 10 degrees to 15 degrees, for example 13.5 degrees, then the rotation lock fork 1 in one embodiment attached to the forming section 31 or have been subjected to the forming section 31 and can without hindrance in the direction toward the open position.

By rotating the lock can 1 into the locking device, of which the locking claw 2 can also be running torque in continuously changing, that is to say that for example also continuously increase.
