TECHNICAL FIELD OF THE INVENTION

The invention relates to a lock assembly for exterior doors of vehicles, in particular rail vehicles, an outer door with such a lock assembly and a rail vehicle with such an outer door.

BACKGROUND OF THE INVENTION

In vehicles such as certain agricultural and construction machinery, but especially in rail vehicles, there is often the problem that the vehicle interior side floor is significantly above the vehicle outside floor, so that for a person who wants to open the door from the outside of the vehicle, a corresponding Door opener, usually a rotary actuator in the form of a door handle or a knob, should be at a different height than a corresponding door opener for a person who wants to open the vehicle door from the vehicle interior.

From the DE 10 2010 005 261 A1 is a vehicle door with a lock assembly is known which has two arranged at different heights rotary actuators, which act on a single door latch, hereinafter referred to as a trap, and allow corresponding doors to be conveniently opened both from the vehicle inside and from the vehicle outside , The door also has a latch with a so-called panic release, as is known from buildings. In this case, the bolt can be moved from the outside of the door only by means of a key from the inside of the door but also by operating the acting on the door latch rotary actuator in an open position, so that in particular in case of emergency persons with such a door equipped vehicle can always leave, even if the door is locked from the outside should be. In certain applications, however, there is a desire to provide doors with more than one trap and possibly more than one bar to ensure a particularly stable closed position. A solution to this problem is not known yet.

DISCLOSURE OF THE INVENTION

The invention has for its object to provide an outside door for vehicles, especially for rail vehicles, which not only has two arranged at different heights rotary actuator and the ability to complete the door from the outside, but always open the door from the vehicle interior but also has several traps that can be opened together using only one rotary actuator. The object is achieved by a door with the features of claim 1. The subclaims relate to advantageous embodiments and further developments of the door. The independent claim 12 relates to a lock assembly for such an outer door, the independent claim 11 relates to a vehicle equipped with a corresponding door rail vehicle.

The outer door according to the invention makes it possible to synchronize the movement of multiple traps and at the same time to realize a Panikentriegelung in such doors, which have arranged at different heights rotary actuator. Such doors find advantageous use particularly in cab doors of rail vehicles and prevent a driver can be accidentally trapped in a vehicle, since it is always possible for the driver to open the door in a vehicle door according to the invention by simply pressing the door inner side rotary actuator, even if the door should be in the so-called "closed" state realized by at least one latch located in a closed position. In addition, the use of two or more traps and, if appropriate, a plurality of latches makes it possible to lock the door in a particularly secure manner so that the requirements of the most modern high-speed trains can also be met.

For the production of the outer door, more precisely for the production of the lock arrangement arranged in the outer door, it is advantageously possible to use two or more so-called standard locks, the traps and latches of which are synchronized according to the invention. The use of such standard locks simplifies manufacturing and warehousing and has significant cost advantages.

DESCRIPTION OF A PREFERRED EMBODIMENT

In the Fig. 1 is shown in its entirety with 10 designated outer door for rail vehicles, which in this embodiment comprises two traps 12, 12 'and two rotary actuators 14, 14', which are each formed in this embodiment as a doorknob. Here, the term "rotary actuator" is understood to mean control elements which, as a rule, effect a translational movement of the traps by rotation about an axis. Such a rotary actuator can also be realized exclusively by a combination of lock cylinder and key, if the corresponding lock has a so-called. Change, which makes it possible with the key not only the or provided on the door latch, but also the traps in to move an open position. The bolt or bars can be moved from the vehicle outside but only by means of a corresponding key, while it is always possible from the vehicle interior to bring the latch or bars by actuation of the rotary actuator of whatever form in an open position, which will be described in more detail below becomes.

One of the two rotary actuators, namely the door-outside rotary actuator 14, is located in the lower part of the door, while the other rotary actuator, namely the door-side rotary actuator 14 ', is located approximately in the middle of the door. Both rotary actuators, as described below, each act on both traps 12, 12 'and can bring them into a retracted position to open the door. It should be noted at this point that the term "act on" is understood here that a rotary actuator or the like. acting on the traps and / or the bars directly or indirectly, ie with the interposition of mechanical or other coupling means, acts such that a movement of the actuator causes a movement of the traps and / or bars. The door-side rotary actuator 14 'also acts (in the example shown with the interposition of mechanical coupling means) on two bars when they are in the closed position, and makes it possible to bring the latch in a retracted position in the door, while the latch of the Door outside can be moved only by means of a corresponding key, what subsequently in connection with the FIGS. 2 to 4 will be described in more detail.

In the embodiment shown, exactly two rotary actuators are provided, namely one on the inside of the door and one on the outside of the door. However, it is also possible and e.g. in the case of rail vehicles, it makes sense to provide more than two rotary actuators and, in particular, to provide, on the outside of the door, a second external rotary actuator, in addition to the first external rotary actuator 14, as shown; at the level of the inner rotary actuator 14 'to order. This then allows the outside door of a rail vehicle to be conveniently opened both from the rail floor and from a platform. According to the invention, it is important that at least one rotary actuator provided on the inside of the door and at least one rotary actuator provided on the outside are at different heights, which is also achieved if two rotary actuators are provided both inside the door and on the outside of the door, one on each side of the door and one on the outside of the door common axis of rotation are arranged. It should be noted at this point that vehicle doors of the type in question here regularly have a clearly defined Türinnen- and a door outside, where the term inside the door that side of the door is understood, which faces the interior of a vehicle, while the outside of the door to the outside the vehicle has.

In the FIGS. 2 to 4 are each shown plan views of the arranged inside the door lock assembly, in this embodiment, two standard locks, often referred to as "mortise locks" includes, which - as will be described below - were virtually combined to form a castle and in which both the movement of the door traps as well as the movement of the door latch is synchronized. For reasons of clarity, not all of the parts described below have been provided with reference numerals in the drawings.

The Fig. 2 shows the lock assembly in a position in which the traps are in the closed position, the latch but in the unlocked position. A corresponding door is then locked by the traps, but is not locked. Fig. 3 shows the lock assembly in a position in which the traps in the open and the latch are in the unlocked position. Fig. 4 shows the lock assembly in a position in which the traps are in the closed position and the latch in the locked position, so that a corresponding door is closed.

Each of the two door locks comprises a latch 12, 12 ', each associated with two latch levers 16, 18 and 16', 18 ', each latch lever 18, 18' in a conventional manner by means of a rotary actuator, not shown here, the on a provided with a driver 20, 20 'nut 22, 22' acts, can be moved. Each nut 22, 22 'thus serves as a receptacle for a rotary actuator, wherein it can be provided that the nut is accessible from both sides of the door, so that on a rod inserted through the nut two door handles, one on the inside of the door and on the Outside, can be attached. On each driver 20, 20 'acts a return spring 24, 24', so that each rotary actuator is biased to a basic position in which the case is closed. The latch levers 16, 16 ', 18, 18' are biased by corresponding springs 28, 28 'in the position in which the traps 12, 12' are closed.

Each lock also has a bolt 30, 30 ', wherein each bolt has two bolt ends 32, 32', which, for reasons of clarity, only in Fig. 4 have been provided with reference numerals and which protrude in the intended state of installation of the door in the locked state of the door above and below a case out of the door and can engage in corresponding recesses in a door frame, not shown here, to block the door so. Both bars are each provided with a plate, wherein in the drawn state, the plate has been removed from the top in the drawings 30 ', so that only on the lower bar 30 in the drawings, the plate 33 can be seen.

Usually, at least the bottom of the two locks in the drawings is provided with a latch actuating mechanism, for example in the form of a lock cylinder, so that then by turning a suitable key in the region of the keyhole 34, a latch catch not shown here, which engages in the recess 36 of the bolt 30, the latch 30 can be moved. If If desired by the customer, the upper lock in the drawings may also be provided with a corresponding mechanism for actuating the bolt 30 ', for example to allow the driver of a locomotive-equipped locomotive to lock the door from the vehicle. A corresponding vehicle inner side latch actuating mechanism need not necessarily comprise a lock cylinder which can be actuated with a key, but can be realized in a manner known per se in the form of a simple rotary knob.

To allow it now to operate both traps and both bars from both sides of the door with only one handle, and in particular to realize the initially mentioned panic unlocking, which allows all bars by operating a vehicle inside rotary actuator from the locked position in the well Release position, both the movements of the traps and those of the latches must be synchronized such that actuation of each inboard rotary actuator opens all traps and latches, but actuation of each outboard rotary actuator opens only all traps ( unless, as described above, the corresponding rotary actuator would already be realized by a key-lock cylinder combination). The bars are also synchronized so that they are moved together from the vehicle outside by turning a corresponding key.

To synchronize the movement of the two bars 30 and 30 'is used in this embodiment, a mechanical coupling, the two angle lever 37, 37', each with two lever arms 38, 40 and 38 ', 40', of which in each case one, namely the lever arm 38, 38 'engages in a recess on the respective bolt ends 32, 32' opposite end of the bolt 30, 30 ', while the free end of the other lever arm 40, 40' of the two angle lever 37, 37 'connected to a push rod 42 is. A movement of one of the two bars 30 or 30 'is therefore converted via the push rod 42 into a movement of the respective other bar 30' or 30. The push rod is arranged outside the area of the actual locks towards the door interior and lies in particular outside of the lying between the latch levers of two adjacent traps area, so that in this area hereinafter described mechanism for synchronizing the movement of the traps can be arranged. The push rod 42 requires only little space, so that a lock assembly according to the invention can be advantageously retrofitted to existing vehicle doors.

To synchronize the movement of the two traps 12, 12 'is used in this embodiment, a formed of two pull / push rods 44 and 46 and a rotating gate mechanism. In this case, the rotating link in the embodiment shown consists of two rotatably mounted discs 50 and 52 which are interconnected via an intermediate rod 54. Instead of disks also differently shaped plates or components can be used.

On the disc 50, one end of the pull / push rod 44 is articulated, while on the disc 52, one end of the pull / push rod 46 is articulated. The other ends of the two pull / push rods 44 and 46 are articulated at the positions 56 and 56 'on one of the latch levers 18 and 16'. A rotary actuation of a rotary actuator in the region of the lower lock in the drawings then causes via the driver 20 a rotation of the latch lever 18, which on the one hand retracts the latch 12 in the open position, on the other hand, the pull / push rod 44 in the direction of the Zug- / Push rod 46 moves. This movement causes the disc 50 to rotate clockwise in the illustrated embodiment, pulling the intermediate rod 54 downwardly in the drawings so that the disc 52 rotates counterclockwise. This then moves the pull / push rod 46 to the pull / push rod 44 and rotates the latch lever 16 'such that the latch 12' is also forced to the open position. In an analogous manner, rotational actuation of a rotary actuator acting on the nut 22 'via the driver 20' results in movement of the latch lever 18 ', thereby bringing the latch 12' into an open position. But also the latch lever 16 'is moved, which then pushes the pull / push rod 46 in the direction of the pull / push rod 44, this movement causes a movement of the pull / push rod 44 via the rotary link in the manner described, which then via the latch lever 18 brings the latch 12 in the open position.

The rotary actuator acting on the nut 22 'is designed such that its movement also acts on the latch 30' and brings it together with the latch 12 'into an open position. For this purpose, a rocker 58 is provided with two arms in this embodiment, on one arm of the driver 20 'acts and whose other arm is coupled to the latch 30'. If then the nut 22 'rotated by means of a rotary actuator inserted therein, not only open the case 12' and thus also with the case 12 'in the manner described coupled trap 12, but also the latch 30' and thus the with this bar 30 'coupled via the two angle levers 37, 37' and the push rod 42 latch 30, so that the door can be opened by simple operation of the rotary actuator, even when the latch is in the closed position. Conversely, an operation in the manner described above of the lower bolt 30 shown in the drawings by means of a key via the angle lever 37, 37 'and the push rod 42 in a corresponding movement of the upper latch 30' implemented. The bars can in a conventional manner by e.g. a return spring 60, 60 'to be biased to the fully open and fully locked positions, respectively, to prevent the latches from remaining in an incompletely opened or fully closed position, resulting in jamming and possibly locking latch synchronization can.

In the context of the inventive concept, numerous modifications and developments are possible, which relate for example to the number of traps and bars. Thus, it may be appropriate, for example, especially in those doors that are exposed to high pressure differences, to arrange in the upper part of the door another case and possibly another latch, in which case the synchronization of such a bolt and / or such a trap in a simple manner For example, by attaching a further push rod and a further angle lever for bolt synchronization or two other push rods and a rotating backdrop for case synchronization is possible. If, on the other hand, the door is not subject to any particular stresses, it may be sufficient to provide two rotary actuators arranged at different heights, but only one latch, wherein the synchronization can nevertheless be effected via the mechanism described above. A particular advantage of the invention lies in the low installation depth and the fact that standard locks can be used, where by a few additional mechanical components, the bars and traps can be synchronized so that a cost-effective solution can also be created for retrofitting existing exterior doors of vehicles.
