[0003] DESCRIPTION

[0004] Actuating device for a vehicle door of a rail vehicle and door system for a rail vehicle

[0005] The present approach relates to an actuating device for a vehicle door of a rail vehicle and to a door system for a rail vehicle.

[0006] Rail vehicles for transporting passengers typically have multiple doors through which passengers can enter and exit the vehicle. To ensure passenger safety, these vehicles usually incorporate a variety of different safety features.

[0007] Against this background, the task of the present approach is to create an improved actuating device for a vehicle door of a rail vehicle and an improved door system for a rail vehicle.

[0008] This problem is solved by an actuating device having the features of device claim 1 and by a door system according to claim 11.

[0009] The presented approach offers a convenient and compact way to activate and deactivate a door lock function (disabling the door system) and an emergency release function. Advantageously, the door lock activation can be positioned for easy and convenient access by vehicle personnel. Furthermore, the number of components can be reduced, thus saving costs.

[0010] An actuating device for a vehicle door of a rail vehicle is presented, wherein the actuating device comprises a movable actuating element with a manual switch element and a key counterpart element. The manual switch element is designed to be moved into an emergency release position in which an emergency release of the vehicle door is effected by a passenger. 2024ID00144

[0011] 2. The key counterpart is designed to be moved into a locking position using a key element, thereby locking the vehicle door. The key counterpart is designed as a counterpart to the key geometry of the key element. Furthermore, the actuating device has a force transmission element mechanically coupled to the movable actuating element for transmitting mechanical forces from at least one component of the actuating element to at least one component of the vehicle door, in order to unlock the vehicle door in accordance with the emergency release position of the actuating element. Additionally or alternatively, the force transmission element is designed to lock the vehicle door in accordance with the locking position.

[0012] The operating device can be used for a rail vehicle, which is advantageously used for transporting passengers. The vehicle door can be, for example, a single door or, alternatively, a multi-door design. The operating device is preferably located in the area of ​​the vehicle door within the rail vehicle. Advantageously, the operating device can be positioned for easy access. The operating device can be multifunctional, enabling both emergency unlocking, which can be triggered by a passenger, for example, and door locking by rail vehicle personnel. For example, the vehicle door can be locked if it is defective or if it is not to be opened. For this purpose, personnel can use the key element, which can be standardized.The multifunctionality of the actuating device advantageously reduces manufacturing costs, as existing vehicle components can be used to perform both functions, thus eliminating the need for additional parts. Furthermore, available installation space can be used efficiently. For example, the force transmission element can be a Bowden cable or include at least one component thereof. Advantageously, the mechanical coupling of the door lock and the emergency release allows for a temporary reset or deactivation of the door lock function when the emergency release is activated. 2024ID00144.

[0013] 3

[0014] According to one embodiment, the force transmission element can include a spring element, which can be designed to hold the force transmission element in a pre-tensioned state when the actuating element is in a rest position. Advantageously, the use of the spring element allows two opposing forces to be transmitted through the force transmission element.

[0015] Furthermore, the manual switch can be moved from a rest position to the emergency release position to unlock the vehicle door. Additionally, the manual switch, particularly after release and additionally or alternatively by the key counterpart, can be moved from its rest position, opposite to the emergency release position, to the locking position to lock the vehicle door. This means that the manual switch can advantageously be moved in two opposite directions. Each direction can therefore effect or trigger one of the functions.

[0016] According to one embodiment, the key counterpart can be actuated independently of the manual switch element. This means that when the vehicle door is taken out of service and thus when the key counterpart element is actuated, movement of the manual switch element can be avoided.

[0017] The key counterpart can be engaged by the key element through an access opening in the manual switch element. The access opening can therefore be designed as a through-opening to allow access to the key counterpart.

[0018] According to one embodiment, the key counterpart can be designed as a triangular or a square element. The key counterpart can therefore be implemented as a counterpart to a specific geometry of the key element and thus be standardized.

[0019] Furthermore, the key counterpart can be at least partially dependent on the

[0020] The manual switch element may be surrounded by a 2024ID00144.

[0021] 4

[0022] The actuator has a recess in which the key counterpart can be positioned. Alternatively or additionally, the actuator can be designed as an integrated component with the key counterpart and the manual switch element. In this way, a very compact actuator requiring little installation space can be created for a vehicle door component, which also requires minimal installation effort when fitted into a vehicle.

[0023] According to one embodiment, the key counterpart can be arranged adjacent to the hand-operated switch element within a body of the actuator element. Advantageously, the key counterpart can be positioned, for example, below the hand-operated switch element, so that it is easily accessible to vehicle personnel.

[0024] The manual control element can be designed as a rotary lever, a toggle switch, a pull lever, or a pivot lever. This means that the manual control element can advantageously be rotatable, tiltable, sliding, or pivoting, and thus actuated by a rotary, tilting, sliding, or pivoting motion. This advantageously allows the operating device to be used for door systems with different vehicle door types. It also enables simpler and more intuitive operation of the manual control element by the user.

[0025] According to one embodiment, the manual switch element can be designed as a toggle switch so that it can be pressed into the body of the actuator element to move it into the locked position. Additionally or alternatively, the manual switch element can be designed as a toggle switch so that it can be pulled out of the body of the actuator element to move it into the emergency release position. In particular, the manual switch element can remain in the locked position in a state pressed into the body. Advantageously, the position of the manual switch element can visually indicate which function is activated. 2024ID00144

[0026] 5

[0027] Furthermore, the power transmission element can be designed at least partially as a Bowden cable, additionally or alternatively at least partially as a tension / compression element, and additionally or alternatively as a hydraulic element to enable hydraulic power transmission. The tension / compression element can advantageously also be part of a Bowden cable. This design saves space and assembly effort, as no additional external components are required. Likewise, a separate interface for the additional element is unnecessary, thus reducing costs.

[0028] Furthermore, the force applied by the actuating element to activate the emergency release can act as a tensile force on the force transmission element. The force applied by the actuating element to activate the door lock can act as a compressive force on the force transmission element and additionally or alternatively as a release of the force transmission element. Advantageously, this allows the different functions of the actuating device to be performed using one and the same force transmission element.

[0029] Furthermore, a door system for a rail vehicle is presented, wherein the door system comprises a vehicle door and an actuating device in a previously mentioned variant. The actuating device is mechanically coupled to the vehicle door.

[0030] The door system can advantageously be used for a rail vehicle designed to transport passengers. The vehicle door can be, for example, a single door or, alternatively, a multi-door system. Each vehicle door can have one or more door leaves.

[0031] Examples of the approach presented here are explained in more detail in the following description with reference to the figures. These show:

[0042] In the following description of favorable embodiments of the present approach, the same or similar reference numerals are used for the elements shown in the various figures and which have a similar effect, without repeating these elements.

[0043] Fig. 1 shows a schematic representation of a rail vehicle 100 with a door system 105 according to an exemplary embodiment. The rail vehicle 100 is, for example, designed as a passenger transport vehicle. The door system 105 here comprises a vehicle door 110 and an actuating device 115, which is connected to the 2024ID00144

[0044] 7

[0045] The vehicle door 110 is mechanically coupled. The vehicle door 110 is designed, for example, as a single door, but can also be implemented as a multi-door. The actuating device 115 is further designed to enable both emergency operation and thus emergency unlocking of the vehicle door 110, as well as locking of the vehicle door 110. This means that the actuating device 115 is multifunctional. For this purpose, the actuating device 115 has a movable actuating element 120 with a manual switch element 125 and a key counterpart element 130. The manual switch element 125 is designed to be moved into an emergency unlocking position, in which the emergency unlocking of the vehicle door 110 is effected by a passenger. The key counterpart element 130 is designed to be moved into a locking position using, for example, a standardized key element, in which the locking of the vehicle door 110 is effected.The key counterpart 130 is designed as a counterpart to a key geometry of the key element. Furthermore, the actuating device 115 has a force transmission element 135 mechanically coupled to the movable actuating element 120 for transmitting forces to unlock the vehicle door 110 in accordance with the emergency release position of the actuating element 120. Additionally or alternatively, the force transmission element 135 transmits mechanical forces from at least one component of the actuating element 120 to the vehicle door 110 in order to lock and / or disable the vehicle door 110 in accordance with the locking position. Both functions can therefore be achieved by the same force transmission element 135. The force transmission element 135 optionally includes a spring element 140, which is designed to hold the force transmission element 135 in a pre-tensioned state in a rest position.

[0046] According to this embodiment, the door system 105, and thus the rail vehicle 100, additionally has a step device 145, which is or can be mechanically coupled to the actuating device 115, for example via a locking unit 150. The step device 145 is, for example, shaped to bridge a gap between the rail vehicle and, for example, a platform edge in the operating state. This means that, according to this embodiment, the step device 145 is connected by the 2024ID00144

[0047] 8

[0048] Actuating device 115 is or can be actuated. For example, the actuating device 115 is designed to actuate the extension of the footplate 145 in the emergency release position of the actuating element 120 of the actuating device 115 and to lock it in the locking position.

[0049] In other words, the use of the actuating device 115 results in full integration of the door lock activation.

[0050] According to this embodiment, the actuating device 115 is used for both emergency operation and activation of the door lock. The manual switch 125 for emergency operation, which in this embodiment is referred to as the emergency release, is located in a convenient operating position according to standard specifications and can be activated when de-energized. The door lock, which in this embodiment is referred to as the door latch, can only be temporarily reset optionally by the emergency operation. The stroke of the force transmission unit 135, such as a Bowden cable, is used in both directions from a rest position. For example, this is achieved by releasing or pulling the Bowden cable. These two directions are opposite to each other.In this embodiment, the door lock is activated in one direction and the emergency release in the other direction.

[0051] Fig. 2 shows a schematic representation of an embodiment of an actuating device 115 in a rest position 200, which corresponds, for example, to or at least resembles the actuating device described in Fig. 1. According to this embodiment, the actuating device 115 in Fig. 2 also includes the actuating element 120 with the manual switch element 125 and the key counterpart element 130, as well as the force transmission element 135. According to this embodiment, the manual switch element 125 is shown in the rest position 200, which means, for example, that neither the emergency release nor the door lock is activated. 2024ID00144

[0052] 9

[0053] In this embodiment, the manual switching element 125 is designed as a rotary lever. Alternatively, the manual switching element 125 can also be implemented as a toggle switch, a pull lever, or a pivot lever. In this embodiment, the actuating element 120 is arranged in a body 205 of the actuating device 115. More precisely, in this embodiment, the actuating device 115 has a recess 210 in which the actuating element 120 is arranged. In this embodiment, the body 205 has a plurality of mounting openings 207, which are designed, for example, to attach the actuating device 115 to a wall of the rail vehicle. In this embodiment, the manual switching element 125 has an access opening 215 through which the key counterpart 130 can engage with the key element.This means that, according to this embodiment, the key counterpart 130 is at least partially surrounded by the manual switch element 125. Furthermore, the manual switch element 125 is rotatably arranged around the key counterpart 130. Alternatively, the key counterpart 130 is arranged adjacent to the manual switch element 125 in the body 205 of the actuating device 115, for example, below the manual switch element 125. The key counterpart 130 is also designed, or can be designed, as a triangular or square element. According to this embodiment, the key counterpart 130 is designed as a square element, which can be actuated, for example, by a standard square key. According to this embodiment, the key counterpart 130 also has a slot 220, which indicates a position of the key counterpart 130 and thus indicates whether the door lock is activated or deactivated.

[0054] According to this embodiment, the force transmission element 135 is designed at least partially as a Bowden cable, at least partially as a tension / compression element, and / or as a hydraulic element to transmit the force hydraulically. For example, the force applied by the actuating element 120 to activate the emergency release acts as a tensile force on the force transmission element 135. Furthermore, the force applied by the actuating element 120 to activate the door lock acts as a compressive force on the force transmission element 135 and / or as a release of the 2024ID00144

[0055] 10

[0056] Force transmission element 135. This means that, for example, using a pre-tensioned spring element, a spring force acts on the force transmission element 135 in response to the actuation of the key counter-element 130 when the door is locked.

[0057] In other words, according to this embodiment, the actuating element 120 is implemented as a rotary emergency release with integrated door lock activation via a central square drive. The rotary emergency release corresponds, for example, to the manual switch element 125, and the door lock activation refers to the key counterpart element 130, which engages with the key element shaped as a square key to activate the door lock.

[0058] According to this embodiment, the actuating element 120 is implemented as a multi-part element that includes both the key counterpart 130 and the hand switch element 125 and is thus integrated into the hand switch element 125. By turning the key counterpart 130, a movement of the hand switch element 125, designed as a rotary handle, is released in the opposite direction to an emergency operation. This movement is then used via the force transmission element 135, which is designed, for example, as a Bowden cable, to activate the door lock in order to disable and / or lock the vehicle door and / or the door system. If necessary, according to one embodiment, the hand switch element 125 can simply be turned or pulled out of the active door lock position, whereby the door lock function is first, for example, at least temporarily, released and then the emergency operation process is initiated.Similarly, if the optional temporary resetting of the door lock during emergency operation is not desired, the manual release element 125 can be locked from the square spindle when the door lock is activated via the rotation of the square spindle, thus preventing emergency operation even with a locked door system. Additionally or alternatively, the manual release element 125 is not moved when the key-operated counterpart element 130 is actuated. This means that both elements 125 and 130 are independently movable. 2024ID00144.

[0060] Fig. 3 shows a schematic representation of an embodiment of an actuating device 115 in an emergency release position 300. The actuating device 115 corresponds here to that shown in at least one of Figures 1 to 3.

[0061] The actuating device described in Fig. 2. As in Fig. 2, the hand-operated switching element 125 is designed as a rotary lever in this embodiment. In this embodiment, the hand-operated switching element 125 is rotated clockwise relative to the hand-operated switching element described in Fig. 2, for example by 90°, which is symbolically indicated by an arrow. The position of the key-operated counter-element 130 corresponds to the position of the key-operated counter-element 130 in Fig. 2.

[0062] According to this embodiment, the manual switch element 125 can be switched from the rest position to the emergency release position 300 to unlock the vehicle door. Furthermore, the manual switch element, particularly after release and / or by the key counterpart element 130, can be switched from the rest position, opposite to the emergency release position 300, to the locking position to lock the vehicle door, as described, for example, in Fig. 4.

[0063] Fig. 4 shows a schematic representation of an embodiment of an actuating device 115 in a locking position 400. The actuating device 115 corresponds here to that shown in at least one of Figures 1 to 2.

[0064] The actuating device described in Figure 3 is shown. In this embodiment, the manual switching element 125 is shown rotated counterclockwise from the rest position described in Figure 2. In this embodiment, the key counterpart element 130 is actuated to activate the door lock of the vehicle door, which is evident from the horizontal position of the slot 220. For example, the door lock is desired if the vehicle door has a defect.

[0065] Fig. 5 shows a schematic representation of an embodiment of an actuating device 115 in a rest position 200. The actuating device 115 is similar to the actuating device described in at least one of Figures 1 to 4. Unlike in Figures 2 to 4, the hand switch element 2024ID00144

[0066] 12

[0067] In this embodiment, the manual switching element 125 is designed as a toggle switch which, when installed in the actuating device 115, can be tilted about a horizontally extending axis of rotation. Alternatively, the manual switching element 125 can also be implemented in the form of a pivot lever.

[0068] According to this embodiment, the manual switch element 125 can also be described as a flap behind which the key counterpart element 130 is arranged in the body. Also according to this embodiment, the manual switch element 125 has the access opening 215 behind which the key counterpart element 130 is arranged. The key element can therefore engage the key counterpart element 130 through the access opening 215 to activate the door lock.

[0069] In the rest state 200, the hand-operated switching element 125 is flush with the body 205 on at least two opposite sides and, according to this embodiment, on three sides, thus forming a flush surface.

[0070] According to this embodiment, the actuating element 120 is described as an emergency flap actuation with integrated door lock activation via a central square.

[0071] Fig. 6 shows a schematic representation of an embodiment of an actuating device 115 in an emergency release position 300. The actuating device 115 corresponds, for example, to the actuating device described in Fig. 5, with the exception that only the positions of the actuating devices differ. According to this embodiment, the manual switch element 125 is shown pulled out of the body 205, which corresponds to the emergency release position 300 for toggle switches. Alternatively, to move the manual switch element 125 into the locking position, as described in more detail, for example, in Fig. 7, it is pressed into the body 205 of the actuating element 120. In this case, the manual switch element 125 remains in the locking position in a state pressed into the body 205. 2024ID00144

[0072] 13

[0073] Furthermore, the actuating device 115 is similar in its functions to the actuating device described in at least one of Figures 1 to 4.

[0074] Fig. 7 shows a schematic representation of an embodiment of an actuating device 115 in a locking position 400. The actuating device 115 corresponds, for example, to the actuating device described in Figures 5 to 6, with the only difference being the position of the actuating elements. According to this embodiment, the hand switch element 125 is shown pressed into the body 205, as already described, for example, in Fig. 6. The position of the key counter-element 130 corresponds to the position of the key counter-element shown in Fig. 4. Overall, the actuating device shown in Fig. 7 is similar in its functions to the actuating device described in at least one of Figures 1 to 4.

[0075] Fig. 8 shows a schematic representation of an embodiment of an actuating device 115 in a rest position 200. The actuating device 115 is similar, for example, to the actuating device described in Figures 5 to 7, in particular to the actuating device described in Fig. 5. According to this embodiment, only the access opening 215 is larger than the access opening shown in Fig. 5. The key counterpart 130 is connected centrally to the body 205.

[0076] Fig. 9 shows a schematic representation of an embodiment of a locking unit 150, which is at least similar to the locking unit 150 described or at least mentioned in Fig. 1. The locking unit 150 is designed, for example, to transmit the actuation of the actuating device to a foot pedal of the door system. The locking unit 150 is coupled, for example, to at least one Bowden element 900 for transmitting the actuation to the foot pedal and, according to this embodiment, to two Bowden elements 900. The at least one Bowden element 900 is, for example, designed as a push-pull element. According to this embodiment, the locking unit 150 has at least 2024ID00144

[0077] 14 a coupling section 905 which is coupled to the key counterpart 130 of the actuating device.

[0078] If an embodiment includes an “and / or” connection between a first feature and a second feature, this is to be read as meaning that the embodiment according to one embodiment has both the first feature and the second feature, and according to another embodiment either only the first feature or only the second feature.
