[0003] [Patent Document 1] Patent Publication No. 2021-24417 Summary of the Invention [Problem to be solved by the invention]

[0004] In recent years, there have been incidents of suspicious individuals carrying weapons such as knives in the passenger compartments of railway vehicles. Passengers have nowhere to escape when the vehicle is moving, and may not have any means to protect themselves from such incidents. While it may be possible to store protective shields in the crew cabin, if the incident occurs far from the crew cabin, the protective shields cannot be used quickly.

[0005] Therefore, one aspect of the present disclosure aims to enable passengers to quickly protect themselves when trouble occurs in the passenger compartment of a railway vehicle. [Means for solving the problem]

[0006] A railway vehicle armrest partition according to one aspect of the present disclosure includes a partition frame provided at an end of a long seat of the railway vehicle, and a protective shield including a protective plate and a handle. The partition frame includes a shield storage space that stores the protective shield with the thickness direction of the protective plate oriented in the longitudinal direction of the vehicle, and a shield exit through which the protective shield stored in the shield storage space can pass to the outside. [Effects of the Invention]

[0007] According to one aspect of the present disclosure, in the event of a problem in the passenger cabin, passengers can quickly protect themselves by removing a protective shield from the partition frame in the armrest through a shield outlet. [Brief explanation of the drawings]

[0009] Hereinafter, an embodiment will be described with reference to the drawings. In the following description, the direction in which a vehicle travels is defined as the longitudinal direction of the vehicle (front-rear direction), and the lateral direction perpendicular to the longitudinal direction is defined as the vehicle width direction (left-right direction of the vehicle).

[0010] FIG. 1 is a side view of a passenger compartment of a railway vehicle 1 as viewed from the inside in the vehicle width direction. As shown in FIG. 1, a side structure 3 constituting a carbody 2 of the railway vehicle 1 has a door opening 4 and a window opening 5. A side door 6 is provided in the door opening 4. A transparent panel 7 is provided in the window opening 5. A long seat 8 is installed below the window opening 5 on the inside side of the car of the side structure 3. The long seat 8 extends in the vehicle length direction along the side structure 3 so that passengers are seated facing inward in the vehicle width direction. Armchair partitions 10 are provided at both ends of the long seat 8. The armchair partitions 10 separate the space facing the side door 6 in the vehicle width direction from the long seat 8.

[0011] FIG. 2 is a front view of the armrest partition 10 of FIG. 1 as viewed from the longitudinal direction of the vehicle. As shown in FIG. 2, the long seat 8 includes a seat support 8a, a seat cushion 8b, and a back cushion 8c. The seat support 8a is installed on a floor panel 9 that defines the passenger compartment. The seat support 8a may be supported by the side structure 3 at a distance from the floor panel 9. The seat cushion 8b is supported from below by the seat support 8a. The back cushion 8c extends upward from the end of the seat cushion 8b closer to the side structure 3. The side structure 3 has an outer panel 3a facing the outside of the vehicle and an inner panel 3b that is spaced inward in the vehicle width direction from the outer panel 3a and faces the passenger compartment. The back cushion 8c is fixed to the inner panel 3b.

[0012] The armrest partition 10 is provided at the longitudinal end of the long seat 8. The armrest partition 10 extends in a direction perpendicular to the longitudinal direction of the vehicle. In other words, the thickness direction of the armrest partition 10 is oriented in the longitudinal direction of the vehicle. When viewed from the longitudinal direction of the vehicle, the armrest partition 10 overlaps with the seating space adjacent to the seat cushion 8b above and adjacent to the back cushion 8c on the inner side in the vehicle width direction. The armrest partition 10 is fixed to the seat support 8a and the inner panel 3b. The armrest partition 10 includes a partition frame 11, a protective shield 12, a lid 13, and a lid lock 14.

[0013] The partition frame 11 has a shield storage space S and a shield outlet Q. The shield storage space S stores the protective shield 12 with the thickness direction of the protective shield 12 facing the longitudinal direction of the vehicle. The shield outlet Q has a shape and size that allows the protective shield 12 to pass through. The shield outlet Q opens the shield storage space S in the shield removal direction that is perpendicular to the thickness direction of the armrest partition 10. For example, the shield outlet Q opens the shield storage space S upward.

[0014] The partition frame 11 has guides 25 that guide the protective plates 31 entering and exiting the shield storage space S through the shield exit Q. The partition frame 11 defines an opening P that opens the shield storage space S in the thickness direction of the armrest partition 10. The opening P is smaller than the protective plates 12 when viewed in the thickness direction of the armrest partition 10. When the protective shields 12 are stored in the shield storage space S, they encompass the opening P when viewed in the thickness direction of the armrest partition 10. When stored in the shield storage space S, the protective shields 12 are exposed to the outside through the opening P. In other words, the protective shields 12 stored in the shield storage space S function as a partition for the armrest partition 10.

[0015] The protective shield 12 includes a protective plate 31 and a handle 32. The handle 32 is provided on only one side of the protective plate 31. When the protective shield 12 is stored in the shield storage space S, the handle 32 is disposed in the opening P when viewed from the thickness direction of the armrest 10. In other words, when the protective shield 12 is stored in the shield storage space S, the handle 32 is exposed to the outside of the partition frame 11.

[0016] The lid 13 closes the shield outlet Q from above so that the shield outlet Q can be opened and closed. The lid 13 is attached to the protective plate 31 so as to be separable from the partition frame 11. In other words, when the protective shield 12 is removed upward through the shield outlet Q, the lid 13 moves upward together with the protective shield 12.

[0017] The opening P is continuous with the shield outlet Q so as to include the movement trajectory T of the handle 32 when the protective shield 12 is removed upward through the shield outlet Q. In other words, the partition frame 11 opens the opening P upward when viewed from the thickness direction of the sleeve partition 10. The partition frame 11 has, for example, a U-shape when viewed from the thickness direction of the sleeve partition 10.

[0018] The lid lock 14 includes a locking member 41 and an actuator 42. As will be described later, the locking member 41 is operable between a locked position that keeps the lid 13 closed and an unlocked position that allows the lid 13 to be opened. The actuator 42 is disposed in the space between the inner plate 3b and the outer plate 3a. The actuator 42 drives the locking member 41 to move it between the locked position and the unlocked position. The actuator 42 is, for example, an electric motor, but may also be a hydraulic actuator or a pneumatic actuator.

[0019] 3 is a cross-sectional view taken along line III-III in FIG. 2. As shown in FIG. 3, the partition frame 11 has a first side panel 21, a second side panel 22, an outer end panel 23, and an inner end panel 24. The first side panel 21 faces the long seat 8 and is oriented in the thickness direction of the armchair partition 10. The second side panel 22 is disposed parallel to the first side panel 21 and spaced apart from the first side panel 21 on the side away from the long seat 8. The outer end panel 23 faces in a direction perpendicular to the thickness direction of the armchair partition 10 and connects the outer edges of the first side panel 21 and the second side panel 22 to each other. The outer end panel 23 extends along the outer edges of the first side panel 21 and the second side panel 22.

[0020] The inner edges of the first side plate 21 and the second side plate 22 define an opening P. The inner end plate 24 connects the inner edges of the first side plate 21 and the second side plate 22 to each other. The outer end plate 23 and the inner end plate 24 are not located at positions corresponding to the shield outlet Q. The inner end plate 24 extends along the inner edges of the first side plate 21 and the second side plate 22. The inner end plate 24 has a slit 24a extending in the extension direction thereof, through which the protective shield 12 is inserted. The slit 24a has a width that allows two overlapping protective plates 31 to be inserted therethrough. The slit 24a can also function as a guide together with the guide 25, which will be described later.

[0021] In the internal space defined by the first side plate 21, the second side plate 22, the outer end plate 23 and the inner end plate 24, a guide 25, a guide support bracket 26, a receiver 27 (see Figure 2), a fixed bracket 28 (see Figure 2), and a fixed bracket 29 are arranged.

[0022] The guides 25 guide the side edges of the protective shields 12 placed in the shield storage space S. The guides 25 restrict displacement of the protective shields 12 at least in the vehicle width direction. In this embodiment, the guides 25 are guide rails that extend in the vertical direction, which is the shield removal direction of the protective shields 12. The guides 25 have a concave cross-sectional shape that opens toward the shield storage space S when viewed from the vertical direction. In other words, the guides 25 also restrict displacement of the protective shields 12 in the vehicle longitudinal direction. In this embodiment, because two protective shields 12 are stored in the shield storage space S, the guides 25 have a concave cross-sectional shape that allows the side edges of two overlapping protective plates 31 to fit into each other.

[0023] The guide support bracket 26 connects the guide 25 to the first side plate 21 or the second side plate 22. The guide support bracket 26 is fixed to the first side plate 21 or the second side plate 22 and is also fixed to the guide 25. The fixed bracket 29 faces the inner plate 3b while being fixed to the first side plate 21 or the second side plate 22, and is fixed to the inner plate 3b by bolts B.

[0024] Returning to Figure 2, the receiver 27 is disposed below the partition frame 11. The receiver 27 supports from below the lower edge of the protective shield 12 stored in the shield storage space S. The receiver 27 is fixed to the first side plate 21 or the second side plate 22 via a fixing bracket 28. The first side plate 21 (see Figure 3) is fixed to the seat support 8a by a bolt B.

[0025] Fig. 4 is a cross-sectional view taken along line IV-IV in Fig. 2. As shown in Fig. 4, the lid 13 is detachably fitted over the entire upper ends of the two protective plates 31. The lid 13 has a concave cross-sectional shape into which the upper ends of the two overlapping protective plates 31 are inserted. When the protective shield 12 is stored in the shield storage space S, the lid 13 is placed on the upper ends of the first side plate 21 and the second side plate 22 so as to close the shield outlet Q.

[0026] The locking member 41 is operable between a locked position X, which keeps the lid 13 closed, and an unlocked position Y, which allows the lid 13 to be opened. The locked position X is located on the movement path of the lid 13 when viewed from the vehicle width direction, and specifically, is located directly above the lid 13. The unlocked position Y is located outside the movement path of the lid 13 when viewed from the vehicle width direction, and specifically, is located at a position offset from the locked position X in the vehicle longitudinal direction.

[0027] If the actuator 42 generates a rotational driving force, the locked position X and the unlocked position Y may be positioned along the rotational trajectory of a member rotated by the rotational driving force of the actuator 42, or a conversion mechanism that converts rotational motion into linear motion, such as a rack and pinion, may be provided in the actuator 42. If the actuator 42 generates a linear driving force, the locked position X and the unlocked position Y may be positioned along the linear motion trajectory of the actuator 42.

[0028] FIG. 5 is a block diagram of an armrest partition system 50 using the armrest partition 10 of FIG. 2. As shown in FIG. 5, the armrest partition system 50 includes a controller 51, a plurality of cabin operation interfaces 52, a driver's cab operation interface 53, and the armrest partition 10. The controller 51 includes a processing circuit. The processing circuit includes, for example, a processor and a memory. The processor may include, for example, a CPU (Central Processing Unit). The memory may include a system memory and a storage memory. The system memory may include a RAM. The storage memory may include a hard disk, a flash memory, etc. The storage memory stores a program. A configuration in which the processor executes the program read into the system memory is an example of a processing circuit.

[0029] The functions of the controller elements disclosed herein can be performed using circuits or processing circuits, including general-purpose processors, special-purpose processors, integrated circuits, ASICs (Application Specific Integrated Circuits), conventional circuits, and / or combinations thereof, configured or programmed to perform the disclosed functions. A processor is considered a processing circuit or circuit because it includes transistors and other circuitry. In this disclosure, a circuit, unit, or means is hardware that performs the recited functions or hardware that is programmed to perform the recited functions. The hardware may be hardware disclosed herein or other known hardware that is programmed or configured to perform the recited functions. Where the hardware is a processor, which is considered a type of circuit, the circuit, means, or unit is a combination of hardware and software, and the software is used to configure the hardware and / or processor.

[0030] The cabin operation interface 52 is arranged so as to be operable by passengers in the cabin of the car body 2 (see FIG. 1). The driver's cab operation interface 53 is arranged so as to be operable by a crew member in the driver's cab of the railway vehicle 1. The cabin operation interface 52 and the driver's cab operation interface 53 are, for example, an emergency button or a lock operation switch.

[0031] When trouble occurs in the passenger compartment of the railway vehicle 1 due to a suspicious person carrying a weapon such as a knife, the passenger operates the passenger compartment operation interface 52. When the crew notices the trouble, the crew may operate the driver's cab operation interface 53. When the passenger compartment operation interface 52 and the driver's cab operation interface 53 are operated, they transmit a predetermined emergency signal to the controller 51.

[0032] When the controller 51 receives an emergency signal generated by operation of the driver's cab operation interface 53 or any one of the multiple passenger compartment operation interfaces 52, it controls the actuators 42 of all the armrest partitions 10 to move the locking members 41 (see Figure 3) from the locked position X to the unlocked position Y.

[0033] Fig. 6 is a front view illustrating the removal of the protective shields 12 from the armrest 10 of Fig. 2. As shown in Fig. 6, when the lid lock 14 is unlocked, a passenger can remove the protective shields 12 upward from the shield storage space S through the shield outlet Q by grasping the handle 32 of the protective shields 12 and sliding the protective shields 12 upward. At that time, the lids 13 move upward integrally with the protective plates 31. By removing the lids 13 from the protective shields 12, the two stacked protective shields 12 are separated from each other.

[0034] According to the configuration described above, when trouble occurs in the passenger cabin, passengers can quickly protect themselves from suspicious individuals by removing the protective shield 12 from the shield storage space S of the partition frame 11 through the shield exit Q.

[0035] The shield exit Q opens the shield storage space S in the shield removal direction perpendicular to the thickness direction of the armrest 10. Therefore, the protective shield 12 is removed in the direction perpendicular to the thickness direction of the armrest 10, and the protective shield 12 can be removed smoothly even if other passengers are seated in the long seats 8.

[0036] The partition frame 11 includes a guide 25 that guides the protective plate 31 from the shield storage space S to the shield exit Q. Therefore, passengers can smoothly remove the protective shield 12 stored in the shield storage space S of the partition frame 11 from the shield exit Q.

[0037] The partition frame 11 defines an opening P that opens the shield storage space S in the thickness direction of the armrest partition 10 and is smaller than the protective plate 31 when viewed from the thickness direction of the armrest partition 10, and the protective shields 12 are exposed to the outside through the opening P when stored in the shield storage space S. Therefore, passengers can visually confirm the presence of the protective shields 12 in the armrest partition 10 and can touch the protective shields 12 stored in the shield storage space S. Furthermore, by providing the opening P in the partition frame 11 and allowing the protective shields 12 to also serve as a partition for the armrest partition 10, the weight of the partition frame 11 can also be reduced.

[0038] The opening P exposes the handle 32 to the outside when the protective shield 12 is stored in the shield storage space S, and the opening P is continuous with the shield exit Q so as to include the movement trajectory T of the handle 32 when the protective shield 12 is removed through the shield exit Q. Therefore, passengers can easily remove the protective shield 12 by grasping the handle 32 of the protective shield 12 stored in the shield storage space S.

[0039] The armrest 10 has a lid that closes the shield outlet Q. Therefore, the protective shield 12 can be prevented from being exposed through the shield outlet Q.

[0040] The lid 13 is attached to the protective plate 31 so as to be separable from the partition frame 11. Therefore, when the protective shield 12 is removed from the shield storage space S, the lid 13 can also be removed.

[0041] The lid lock 14 includes a locking member 41 that is movable between a locked position X that keeps the lid 13 closed and an unlocked position Y that allows the lid 13 to be opened. Thus, the lid lock 14 can prevent the protective shield 12 from easily separating from the partition frame 11.

[0042] The lid lock 14 includes an actuator 42 that operates the locking member 41 between the locked position X and the unlocked position Y. Therefore, the lid lock 14 can be easily released.

[0043] In the sleeve partition system 50, when the controller 51 receives an emergency signal, it controls the actuator 42 to move the locking member 41 to the unlocked position Y. This prevents the lid lock 14 from being unlocked by tampering other than the emergency signal.

[0044] The shield outlet Q may be located on the inner side of the partition frame 11 in the vehicle width direction, so that the protective shield 12 can be taken out from the shield storage space S to the inner side in the vehicle width direction. The opening P that opens the shield storage space S in the thickness direction of the armrest partition 10 does not have to be provided. In other words, the partition frame 11 may be configured to cover the entire protective shield 12 in the stored state.

[0045] The guide 25 may have a concave cross-sectional shape that allows only the side edge of one protective plate 31 to fit therein. In that case, the slit 24a may have a width that allows only one protective plate 31 to pass through. The guide 25 may not have a concave cross-sectional shape, but may have a flat plate shape. In other words, the slit 24a may be responsible for restricting displacement of the stored protective shield 12 in the longitudinal direction of the vehicle, and the guide 25 may restrict only displacement of the protective shield 12 in the width direction of the vehicle.

[0046] The lid 13 may be attached to the partition frame 11 by a hinge or the like so as to be able to open and close the shield outlet Q. When only one protective shield 12 is stored in the shield storage space S, the lid 13 may be fixed to the protective plate 31. The actuator 42 may be disposed on the passenger compartment side. The locking member 41 may be configured to enter an unlocked state by retreating into the space between the inner plate 3b and the outer plate 3a (see Figure 2).

[0047] The cabin operation interface 52 may be an RFID reader. In this case, the RFID reader may read personal data on a commuter pass with an RFID tag carried by a passenger through contactless communication and transmit an emergency signal to the controller 51. The controller 51 may record the personal data read by the RFID reader and control the actuators 42 of all armrests 10 to move the locking members 41 from the locked position X to the unlocked position Y.

[0048] As described above, the above-described embodiments have been described as examples of the technology disclosed in this application. However, the technology of the present disclosure is not limited to these embodiments and can be applied to embodiments in which modifications, substitutions, additions, omissions, etc. are made as appropriate. Furthermore, the components described in the above-described embodiments can be combined to create new embodiments. For example, some configurations or methods in one embodiment may be applied to other embodiments, and some configurations in an embodiment can be separated and arbitrarily extracted from other configurations in that embodiment. Furthermore, the components described in the accompanying drawings and detailed description include not only components essential for solving the problem, but also components that are not essential for solving the problem, and are used to illustrate the technology.
