Description

The invention relates to a mine protection for a door of a military vehicle with a movable locking element, in particular a mine protection, a door for a military vehicle with a mine protection lock and a military vehicle with a mine protection lock. Another object of the invention is a method for unlocking a mine protection lock for a door of a military vehicle, in particular after a mine action, with a movable locking element, in particular a mine protection.

The term "door" in the context of the invention, a movable closure element for closing a vehicle opening, which is particularly suitable for persons, in particular a hinged door, folding door, sliding door, swing door, roller door, revolving door, flap, a lid or hatch.

Doors of military vehicles, in addition to a door lock, which may be configured, for example, in a known manner as a catch, have an additional anti-mine lock, which serves to secure the door in an accident or Blasteinwirkung, for example caused by a mine, against popping and falling , The door lock may also include the anti-mine lock.

Known mine protection locks have a mostly manually movable locking element, which is usually designed as a mine protection. For locking the anti-mine lock, the locking element is movable from an open position along a locking direction of movement into a closed position. To open the latch is moved in the opposite direction.

The locking and unlocking of the mine protection interlock, for example, via a handle which is coupled via a locking mechanism with the locking element. Such mine protection interlock is from the DE 10 2008 039 509 A1 known. Further also discloses the not yet published application DE 10 2010 008 599.5 a mine protection lock with a handle on both the inside and the outside of the door for locking and unlocking the anti-mine lock.

In a Blascheinwirkung, in particular a mine action, the Verrieglungselement is often deformed, bent, for example. Therefore, the mine protection lock to rescue vehicle occupants after a mine action is difficult to open. In this case, there is a risk that the movable locking element is deformed such that it can not be unlocked manually, so that a possibly injured person can not leave the vehicle quickly.

The object of the invention is to provide a mine protection for a door of a military vehicle, which allows the door opening after a mine action even with a deformed locking element.

In a mine protection interlock mentioned above, the object is achieved by a Entriegelungsaktor for unlocking the locking element.

A Entriegelungsaktor is an active element that can release particular kinetic energy for unlocking the locking element. The Entriegelungsaktor can act either directly or via intermediate elements on the locking element or a retaining element holding the locking element. As a result, the locking element does not have to be manually opened by a handle. Rather, a large force for unlocking the locking element can be generated by the Entriegelungsaktor. Thus, a release of the anti-mine lock is also made possible in a deformed by a mine action locking element, so that the vehicle door can be opened after a mine action. After triggering the Entriegelungsaktors this can preferably unlock the locking element automatically.

Preferably, the Entriegelungsaktor on an energy storage, the energy is used to unlock the locking element. The energy store can be configured to store chemical, electrical or mechanical energy. In the unlocking actuator, the stored energy can be converted into kinetic energy for unlocking the locking element.

It is also proposed that the unlocking actuator is designed such that it acts counter to the locking direction of movement of the locking element. In this case, the locking movement direction can be translational or rotational. The fact that the Entriegelungsaktor moves the locking element for unlocking against the locking direction of movement, the anti-mine lock can be solved.

Further, it is advantageous if the Entriegelungsaktor is designed such that it pulls or pushes the locking element. By pulling or pushing, the kinetic energy released by the unlocking actuator can be applied to the Locking element to be passed. In this case, the locking element can be removed from a closed position.

In a preferred embodiment, the mine protection interlock comprises a manual or motorized actuating device for the locking element, wherein the unlocking actuator is arranged in the force flow between the locking element and the actuating device. The actuator can be configured as a handle, as a lever or in particular electrical, hydraulic or pneumatic drive. The unlocking actuator arranged in the power flow between the locking element and the actuating device can be moved when the locking element is locked, in particular in the locking direction of movement. Alternatively, however, the unlocking actuator can also be arranged in the force flow in such a way that it moves in a direction transverse to the locking direction of movement when the locking element is locked.

In a structural embodiment, the Entriegelungsaktor is coupled to the locking element via a locking mechanism. When coupled by a locking mechanism, the Entriegelungsaktor may be indirectly connected to the locking element. For example, linkage, pivot lever or coupling rods may be provided for coupling the Entriegelungsaktors with the locking element. A locking mechanism has the advantage that the Entriegelungsaktor remote from the locking element and thus the remote from the action of the mine blast, can be arranged. This can increase the availability of the Entriegelungsaktors. Furthermore, a deflection of the movement exerted by the Entriegelungsaktor movement can be made possible by a locking mechanism.

It is also proposed that the mine protection interlock comprises a plurality of locking elements, wherein in each case a Entriegelungsaktor is provided for a locking element, or wherein a Entriegelungsaktor for several, especially for all, locking elements is provided. The fact that the mine protection interlock comprises a plurality of locking elements, the protection against a mine action can be improved. For example, a plurality of locking elements can be arranged on different edges of the door on a door of a military vehicle.

Each of the locking elements may each be connected to an unlocking actuator to enable unlocking after a mine action. In this case, the kinetic energy released by an unlocking actuator can be used substantially completely for unlocking a locking element. Alternatively, a Entriegelungsaktor be provided for a plurality of locking elements. This is particularly advantageous when the locking elements are coupled via a locking mechanism. Then the Entriegelungsaktor can be coupled directly to the locking mechanism and thus act on the locking elements on the locking elements. A locking mechanism can also implement a translational movement of the Entriegelungsaktors in a rotational movement of the locking element.

Preferably, several Entriegelungsaktoren are designed such that they act in the same direction. Because a plurality of unlocking actuators are provided for unlocking, the effect of the unlocking actuators can add up and an increased amount of energy can be released for unlocking. In this case, a plurality of unlocking actuators can act on one locking element as well as a plurality of unlocking actuators can be coupled in such a way via a locking mechanism that they act on a plurality of locking elements. In particular, when a plurality of locking elements are moved in the same direction of movement for locking, it is advantageous if a plurality of Entriegelungsaktoren act in a same, the locking direction of movement opposite direction.

In a constructive embodiment, the Entriegelungsaktor comprises a gas generator known per se. With a gas generator, a gas pressure for unlocking the locking element can be generated. This gas pressure can be directed to a movable element, which can be coupled to transmit the kinetic energy with the locking element.

In a preferred embodiment, the unlocking actuator comprises a known pyrotechnic actuator. In a pyrotechnic actuator chemically bound energy can be converted into kinetic energy. In this case, a piston can be pressed or pulled in the pyrotechnic actuator to the outside. On the other hand, when releasing the chemically bound energy, a cocked spring can also be released to initiate a movement.

It is also proposed that the unlocking actuator comprises a piston cylinder. In a piston cylinder, the stored energy can be converted into kinetic energy. In particular, a piston cylinder allows the initiation of a linear movement. The piston cylinder of the Entriegelungsaktors may be coupled to the locking element such that it pulls or pushes the locking element.

In a particularly advantageous embodiment of the Entriegelungsaktor is electrically and / or mechanically triggered. The unlocking actuator may comprise an electric and / or mechanical detonator for triggering. As a result, the unlocking actuator for unlocking the anti-mine lock can be manually or electrically activated.

It is also advantageous if a sensor for detecting a mine action and for releasing the Entriegelungsaktors is provided after the detection of a mine action. Before the sensor detects a mine action, the Entriegelungsaktor may be disabled. As a result of a mine action, the sensor can cause a release of the Entriegelungsaktors. By releasing the unlocking actuator can be put into a state in which it can be triggered. The sensor may be connected to the Entriegelungsaktor directly or via a control unit.

It is particularly advantageous if the sensor is a shock sensor. With a shock sensor, blast or mine actions as well as accidents and similar occurrences, which can cause a deformation of the locking element, can be detected.

It is also proposed that a guide is provided for guiding the movement of the locking element in the direction of movement. The locking element may be guided in a linear guide along a direction of movement. The guide may cause both the movement for locking and the movement for unlocking.

In a constructive embodiment, the guide comprises an outer guide element and an inner guide element. In this case, the inner guide element can be positively connected to the locking element. The inner guide member may be movably supported in the outer guide member. The inner and the outer guide element may be designed to be movable relative to each other in the sense of a sliding bearing. In another embodiment, the inner guide element is connected via a frictional engagement with the outer guide element. In this case, a relative movement between the outer and the inner guide element only begin when the locking element is bent.

Preferably, the guide for unlocking a deformed locking element is designed such that, in addition to a movement of the locking element in the direction of movement also allows a movement transversely to the direction of movement. A deformed locking element may be so bent due to a mine action that it can not be moved against the locking direction of movement by the guide for unlocking. In this case, it is advantageous if the guide also allows a movement transversely to the direction of movement and the locking element tilted by the guide can be moved.

In this context, it is proposed that the inner guide element is formed transversely to the direction of movement elastic. An elastic inner guide element makes it possible to move a bent locking element for unlocking by the guide. In this case, the locking element can be moved by the Entriegelungsaktor substantially counter to the locking direction of movement through the guide, while tilting of the locking element are made possible by the elastic design of the inner guide member.

In another embodiment, the Entriegelungsaktor is arranged such that it acts on a retaining element holding the locking element in the locking position. Thus, the locking element can also be unlocked by movement of the retaining element. The retaining element can be arranged on the vehicle door frame or on the vehicle door. It is also possible that the anti-mine lock, in particular for each locking element, has at least two retaining elements, namely a door-side and a frame-side retaining element. The locking element can then engage in the locking position in both retaining elements. Particularly preferably, the door-side holding element is moved by Entriegelungsaktor, so that the locking element is released when the door is opened to the outside.

With regard to an aforementioned door for a military vehicle, it is proposed to achieve the abovementioned object that an above-described anti-mine lock be provided. Thereby, the opening of the door can be made possible even with a deformed after a mine action locking element. The already described advantageous embodiments of the mine protection lock can be used in a corresponding manner in the door according to the invention.

In a military vehicle mentioned above, the above object is achieved by a mine protection lock described above. As a result, the recovery of the vehicle crew after a mine action is also possible with a deformed Verrieglungselement.

Preferably, the Entriegelungsaktor is arranged on a door of the vehicle. It can the Entriegelungsaktor in the region of the locking element on which it acts, be arranged.

In an alternative embodiment, the Entriegelungsaktor is arranged on a door frame fixed vehicle part. The Entriegelungsaktor can be arranged in particular on the vehicle pan or the vehicle body.

In a particularly advantageous embodiment, the military vehicle comprises a triggering device for triggering the Entriegelungsaktors that can be operated from within and / or outside of the vehicle. The triggering device can be designed as a mechanical or electrical switch or as a sensor. With a triggering device arranged inside the vehicle, the vehicle crew can undertake the unlocking of the anti-mine lock. In a tripping device arranged outside the vehicle, it is possible for the mine protection interlock to be unlocked by rescue workers for opening the vehicle door.

Incidentally, the developments mentioned in the above-described mine protection lock can be used in a corresponding manner in the military vehicle according to the invention.

With regard to a method mentioned at the outset, it is proposed to achieve the abovementioned object that an unlocking actuator unlocks the locking element. Through a Entriegelungsaktor the locking element can be solved even in the deformed state after a mine action. Thus, the door of the military vehicle can be opened to rescue the crew.

It is also proposed that energy stored in the unlocking actuator be released for unlocking. The released energy can be converted into kinetic energy for unlocking the locking element.

Preferably, a mine action is detected by means of a sensor and the unlocking actuator is then released. By releasing the Entriegelungsaktors by means of a detection of mine action can be ensured that the Entriegelungsaktor can be triggered only after a mine action. In particular, in a non-reusable Entriegelungsaktor it may be advantageous to prevent the unwanted release of the Entriegelungsaktors by a release. Furthermore, unintentional or unauthorized opening of the door is prevented.

Particularly preferably, the unlocking actuator is triggered by a triggering device which is arranged inside and / or outside the vehicle. After releasing the Entriegelungsaktors the Entriegelungsaktor can be triggered by a triggering device.

Furthermore, the developments described in relation to the mine protection lock according to the invention can be used in a corresponding manner in the inventive method for unlocking.

The Entriegelungsaktor invention can be particularly well in those already mentioned in the DE 10 2008 039 509 A1 and DE 10 2010 008 599.5 described mine protection locks are used, so that the embodiments described therein are hereby incorporated in full in the present application.

A third embodiment of the mine protection interlock is in the 3 shown. The locking elements 2.7 . 2.8 . 2.9 are at the vehicle door 1 arranged and via a locking mechanism 4.1 coupled such that a rotational movement of the locking mechanism 4.1 counterclockwise is converted into a linear locking movement. Further, at the vehicle door 1 an unlocking actuator 3.7 arranged, via the locking mechanism 4.1 with the locking elements 2.7 . 2.8 . 2.9 is coupled. Here is the Entriegelungsaktor 3.7 dimensioned such that it has a sufficient amount of energy for unlocking the locking elements 2.7 . 2.8 . 2.9 can release.

In the 4 a fourth embodiment of the anti-mine lock is shown, which differs from the in 3 shown embodiment differs in that they only two locking elements 2.10 . 2.11 which has a locking mechanism 4.2 with an unlocking actuator 3.8 are connected.

A fifth version of the mine protection interlock is in the 5 shown. Here are the right edge of the door 1 three locking elements 2.12 . 2.13 . 2.14 arranged, in each case over the motor drives 5.1 . 5.2 . 5.3 can be locked. In addition, three unlocking actuators are on the vehicle frame, not shown 3.9 . 3.10 . 3.11 provided to the locking elements 2.12 . 2.13 . 2.14 to press for unlocking after a mine action.

The 6 shows an enlarged sectional view through the upper locking element 2.12 of the 5 , On the inside of the vehicle door 1 is a drive 6 arranged, which may be electrical, hydraulic or pneumatic and the locking element 2.12 in engagement with the holding elements 17.1 and 17.2 can bring. Here is the holding element 17.1 firmly with the vehicle door frame 7 connected and the holding element 17.2 at the vehicle door 1 arranged. In the illustration in 6 is the locking element 2.12 in its open position. For locking the locking element 2.12 to the left through the retaining elements 17.1 and 17.2 be moved and lock them together in the closed position. On the vehicle frame is also the Entriegelungsaktor 3.9 mounted, which is the locking element 2.12 for unlocking to the right from the holding elements 17.1 and 17.2 can squeeze out.

A sixth embodiment of a mine protection interlock is in the 7 shown. Here are at the vehicle door 1 three locking sockets 8.1 . 8.2 . 8.3 arranged. At the vehicle frame 7 there is also an operating lever 9 that has a locking mechanism 4.3 with three locking elements 2.15 . 2.16 . 2.17 is connected, which engages with the locking sockets 8.1 . 8.2 . 8.3 can be brought, cf. also 8th , It is about the locking mechanism 4.3 a rotational movement on the actuating lever 9 in a translational movement on the locking elements 2.15 . 2.16 . 2.17 diverted.

The locking elements 2.15 . 2.16 . 2.17 can be moved upwards for locking and for unlocking. Even with deformed locking elements 2.15 . 2.16 . 2.17 to allow unlocking the mine protection after a mine action, are unlocking actuators 3.12 . 3.13 . 3.14 on the vehicle frame 7 arranged. These unlocking actuators 3.12 . 3.13 . 3.14 act in the same direction on the locking mechanism 4.3 one that the locking elements 2.15 . 2.16 . 2.17 from the locking sockets 8.1 . 8.2 . 8.3 can be pulled.

Another embodiment of the anti-mine lock on a military vehicle, which is particularly suitable as a retrofit solution is in the 9 to 12 shown. There are three locking elements 2.18 . 2.19 . 2.20 provided, which at the door 1 are arranged and the door 1 can lock against the vehicle frame. The locking elements 2.18 . 2.19 . 2.20 are with a locking mechanism 4.4 connected. It is between the locking element 2.18 and the locking mechanism 4.4 an unlocking actuator 3.15 arranged in the power flow. When locking the locking element 2.18 the unlocking actuator moves 3.15 in the locking direction of movement with. Furthermore, the Entriegelungsaktor 3.15 be activated to unlock the mine protection interlock, wherein he the locking element 2.18 can pull against its locking direction of movement.

Furthermore, in the area of the locking elements 2.19 and 2.20 the unlocking actuators 3.16 and 3.17 arranged. These unlocking actuators 3.16 . 3.17 are not arranged in the power flow and therefore change when locking the locking elements 2.19 . 2.20 her position is not. Also these unlocking actuators 3.16 . 3.17 can be activated to unlock the mine protection lock, where they are the locking elements 2.19 . 2.20 can pull against their locking direction.

In the detailed representation of the locking element 2.20 in the 10 is also a guide 12 for guiding the locking element 2.20 shown. The schematic representation of the leadership in the 11 lets recognize that the guide is made of an outer guide element 10 and an inner guide element 11 consists. The outer guide element 10 is stuck with the vehicle door 1 connected and allows a guide of the locking element 2.20 in the vertical direction. The inner guide element 11 is elastic and also allows limited movement of the locking element 2.20 in a direction transverse to the locking direction of movement. The inner guide element can be designed in particular as a rubber element. During a movement of the unbent locking element 2.20 this moves relative to the inner guide 11 , wherein the inner guide element 11 not due to the frictional engagement relative to the outer guide element 10 emotional.

In the 12 is the lead from the 11 with a locking element 2.20 represented, which has a deformation, which may be caused for example by a mine action. An unlocking of the locking element 2.20 due to a movement exclusively against the locking direction of movement is not possible due to the deformation. The locking element 2.20 would be in such a movement in the leadership 12 get stuck. The mine protection lock could not be unlocked. However, due to the elastic, inner guide element 11 in addition a movement of the locking element 2.20 allows transverse to the locking direction of movement. Therefore, the locking element 2.20 when retreating through the leadership 12 be tilted so that it is movable in the deformed state by the guide. Furthermore, the inner guide element can also be 11 relative to the outer guide element 10 move so that within the guide a clearance for the deformed latch 2.20 is created.

All of the above-described embodiments of the mine protection lock according to the invention have in common that provided an unlocking actuator for unlocking a locking element is. Furthermore, in such mine protection interlocks, a sensor 20 be provided, which detects a mine action with locked mine protection interlock. As a result, the Entriegelungsaktoren 3.1 to 3.17 be released by the sensor. After releasing the unlocking actuators 3.1 to 3.18 are the Entriegelungsaktoren 3.1 to 3.18 not yet activated, but merely put into a ready-to-use state. The ready-to-use unlocking actuators 3.1 to 3.17 can be activated by a triggering device and thus the movable locking elements 2.1 to 2.21 spend from the closed position in an open position. According to 4 is the sensor 20 directly connected to the Entriegelungsaktor

The following is based on the Entriegelungsaktors 3.17 an embodiment of a Entriegelungsaktors will be described, which in this way also in the Entriegelungsaktoren 3.1 - 3.16 can be used:
The unlocking actuator 3.17 includes two piston rods 13.1 . 13.2 , which are arranged next to the door mechanism, cf. 10 , In addition, the Entriegelungsaktor 3.17 a mechanical detonator and an electric detonator. Furthermore, the unlocking actuator comprises 3.17 a gas generator which can be selectively activated via one of the two detonators. The gas generator serves as a chemical energy storage, which generates a gas pressure when activated. The released gas is passed through a channel in a piston cylinder. When the gas flows into the piston cylinder, an actuator piston is pulled into the piston cylinder.

Such an unlocking actuator 3.17 is suitable for pulling a locking element. It would also be possible to specify a Entriegelungsaktor which acts oppressive on a locking element.

The described anti-mine locks can be used on a military vehicle and allow the rescue of the vehicle crew after a mine action even with a deformed locking element.
