Definitions

  • the present invention relates to a locking device for vehicle doors, in particular for pressure-tight doors in the interior of rail vehicles, and to a rail vehicle having a door with such a locking device.
  • a locomotive driver's cab is separated from the engine room by a partition. A door is built into this partition, which must perform certain functions to ensure the safe operation of a locomotive. First and foremost, an escape route from the driver's cab must be ensured if there is a risk of collision. Secondly, the engine driver should be given the opportunity to be able to lock the driver's cab in a pressure-tight manner in order to avoid pressure equalization when driving through tunnels and during train encounters.
  • the door is equipped with a locking system consisting of a mortise lock, a lever on the driver's cab side and a door handle on the machine room side.
  • a locking system consisting of a mortise lock, a lever on the driver's cab side and a door handle on the machine room side.
  • components such as a striking plate in the door frame, synonymous with the term "door frame”, and all around sealing seals, in particular hollow chamber seals, are installed on the door leaf and / or the door frame.
  • the lever extends, for example in the form of a bar, across the door leaf and is articulated at both ends.
  • a pressing device hereinafter also referred to as "ratchet"
  • the grater engages with a bolt in an opening in the striking plate which has an oblique edge and is also referred to as a "grater trap”.
  • the door leaf is pressed against the door frame, wherein the door leaf is pressed against peripheral seals on the door frame, or peripheral seals attached to the door leaf are pressed against the door frame.
  • the latch should basically only be able to be actuated for the purpose of pressure-tight locking if the locking tongue engages or has engaged in the lock latch. An earlier actuation of the grater can cause the lock to malfunction. The all-round seals can cause the door to spring back during the closing process. In this situation, if the locking tongue has not yet engaged in the lock latch, but the lock-in can already be actuated and its bolt is extended, it may happen that the lock of the lock-in does not engage in the lock-in latch as intended and instead the bolt against the Presses the door frame or a striking plate attached there, or the door is pulled to the side of the door frame with the extended grater.
  • Known locking devices have a locking device for the latch, which is intended to prevent actuation of the latch before the locking tongue engages in the lock latch.
  • the known solutions are unsatisfactory since they are not free from malfunctions and the locking tongue and the grater can still act independently of one another.
  • DE 10 2010 005 261 A1 started from the problem of making a rail vehicle door lock known from the non-documented prior art more flexible, in such a way that the lock has fewer functional restrictions.
  • the solution of DE 10 2010 005 261 A1 is characterized in that the latch has a holding surface which can be contacted by blocking with a counter-holding surface of the blocking device.
  • the solution of DE 10 2010 005 261 A1 consists essentially in having the blocking device no longer act on an auxiliary pawl but directly on the lock pawl, the lock pawl now being able to be locked not only in the blocking position, but also being able to assume different positions even when the blocking device is activated.
  • EP 0 668 425 A1 discloses a door lock with a latch which can be actuated via a nut part and with a bolt which is operatively connected to the nut part in such a way that it can be retracted together with the latch.
  • the bolt is retractable against the force of a biasing spring via a gear which has a locking mechanism.
  • the locking mechanism engages the bolt or a gear member in such a way that the bolt can be locked in any retracted position at least in one end section of its retraction movement.
  • the locking mechanism can be released via a position sensor protruding from the door lock, the bolt being extendable under the action of the biasing spring.
  • EP 1 031 686 A2 discloses a lock with a trigger-operated and lockable main latch that snaps into a striker, and with an auxiliary latch that is inserted through the striker when the door is closed and that locks the main latch when inserted.
  • the main latch acts on a locking device which engages the auxiliary latch and holds it in its extended position, such as a locking lever which engages with a control edge on a surface directed against the direction of insertion, in particular on a stop of the auxiliary latch.
  • the inlet surface of the main latch head being in front of the inlet surface of the auxiliary latch head for the advance release of the auxiliary latch lock in the course of the closing process of the door.
  • auxiliary latch pushed in automatically by spring force and retractable by a handle and / or locking cylinder.
  • a tumbler holding the spring-loaded bolt in the retracted position assigned to the bolt which can be swiveled into the release position of the tumbler or rocker when the auxiliary latch is inserted.
  • a bolt or slide is slidably mounted in or on the shaft of the auxiliary trap, which in the inserted position of the auxiliary trap has on the one hand a from the main latch when projecting the same actuable release lever and on the other hand with the tumbler, in particular rocker for kinematically aligning so that it is released only when the main latch protrudes into a latch pocket of the striker, the bolt is released for rushing into its latch pocket of the striker.
  • An object of the invention was to provide an improved locking device in which the grater can only be actuated when the locking tongue engages in the lock latch.
  • the closing tongue moves into the first opening (also referred to as a lock latch) when the door is closed, thus engages in the first opening.
  • the locking tongue and the trigger move relative to one another.
  • the closed state of the door engagement of the locking tongue in the lock latch
  • the locking tongue and the trigger assume a position which is changed relative to one another in comparison to the opened state of the door.
  • the locking tongue projects completely or partially from the locking device, in particular from a housing of the locking device.
  • the locking device is in particular attached to a door leaf and the locking tongue protrudes over an edge of the door leaf.
  • the locking tongue is first moved into the locking device (or into a housing of the locking device) and then, when the door is closed, it is moved out of the locking device again, e.g. by a spring, and engages in the first opening arranged on the door frame.
  • the term "opening” means an opening with a depth extension so that a bolt or a locking tongue can engage. Instead of the term “opening”, the terms “recess” or “recess” can also be used.
  • the locking tongue can assume the same position within the locking device when the door is closed as when the door is open. In the closed state of the door, the closing tongue can also assume a different position within the closing device compared to the opened state of the door.
  • the trigger When the door is closed, the trigger is preferably moved such that it assumes a different position within the closing device when the door is closed than when the door is open.
  • the trigger is moved into the closing device when the door is closed, for example by pressing the door frame, a striking plate or another component provided on the door frame against the trigger.
  • both parts become relative to one another emotional.
  • the locking tongue occupies a different position within the locking device than when the door is open, and the trigger also takes a different position within the locking device when the door is closed than when the door is open, then the positions are from Trigger and locking tongue matched to each other so that both parts are moved relative to each other.
  • the relative movement of the locking tongue and the trigger is used to transfer the pressure device (also referred to as a grater) from the locked state to the unlocked state.
  • the relative movement can only take place, and the unlocking device can only be unlocked when the locking tongue engages in the lock latch.
  • the two components locking tongue and trigger are functionally dependent on each other.
  • the trigger can only move relative to the locking tongue when the locking tongue engages in the lock latch. This ensures that the function of the trigger is linked to the function of the lock tongue.
  • the term “trigger” means that this element, in cooperation with the locking tongue, “triggers” the unlocked state of the pressing device directly or indirectly.
  • the trigger serves to bring the pressing device, in cooperation with the locking tongue, directly or indirectly (for example via a mechanism that is still present) from the locked to the unlocked state.
  • the trigger in cooperation with the locking tongue, causes the pressing device to be held in the locked state as long as the locking tongue does not engage in the first opening and that the pressing device is brought into the unlocked state when the locking tongue engages in the first opening.
  • the trigger is in particular a sliding element. When the door is open, the trigger can protrude with a part of its body out of the locking device and protrude from a door leaf to which the locking device is attached. When the door is closed, all or part of the protruding part of the trigger can be pressed into the locking device.

  • the pressing device is preferably rotatable and the bolt is moved into the friction trap by a rotary movement.
  • the second opening tapers downward and the bolt of the pressing device is turned into the grater trap from above. He grinds down along the sloping edge and presses the door leaf against the frame.
  • the opening with the inclined edge can, for example, have a contour tapering downwards or upwards, in particular a wedge-shaped contour.
  • the door frame has a surface against which the door leaf bears when the door is closed, or an edge against which the door leaf bears when the door is closed.
  • the door can have a seal, with which an intermediate space between the door leaf and frame can be sealed when the door is closed, preferably a circumferential seal for pressure-tight sealing.
  • An example is a hollow chamber seal.
  • the seal can be attached to the frame and / or on the door leaf.
  • the seal can be attached to the surface on which the door leaf rests when the door is closed, or on the edge against which the door leaf rests when the door is closed.
  • the closing tongue and the trigger are preferably coupled to one another.
  • the trigger and the locking tongue are connected to a mechanism, also referred to as a "trigger mechanism", which is moved by the relative movement of the trigger and the locking tongue, and which transfers the pressing device from the locked state to the unlocked state.
  • the mechanism is preferably movable relative to the trigger and closing tongue, preferably rotatable and / or displaceable.
  • the mechanism is a locking / unlocking device which is movably coupled to the locking tongue and to the trigger, preferably articulated, so that the locking / unlocking device is caused by the relative movement of the locking tongue and trigger acts on the pressing device and transfers the pressing device from the locked state to the unlocked state.

In other words, the locking device blocks the pressing device in the first position.
  • the locking device In the second position, the locking device preferably does not engage in the pressing device, so that movement of the pressing device and insertion of the bolt of the pressing device into the second opening are made possible.
  • the trigger is movable parallel to the locking tongue, and at the time when the locking tongue engages in the first opening arranged on the door frame, the trigger is not movable by the same distance as the locking tongue, so that when the locking tongue engages in the first opening, a Relative movement between Trigger and locking tongue can be generated.
  • the trigger can have the form of a bolt and can be arranged parallel and adjacent to the locking tongue.
  • a special mechanism works as follows: When a door is open, the locking tongue and the trigger protrude from the locking device and protrude from the door leaf, preferably by the same distance.
  • the locking tongue and the trigger are first moved into the locking device so that the door leaf can be moved past the edge of the door frame.
  • the locking tongue reaches the lock latch, it engages in the lock latch and moves out of the locking device and the door leaf again. Then the door is closed.
