Description

[Technical Field]

[0001] The present invention relates to a railway vehicle in which handrails that also serve as self-defense tools are provided inside the vehicle. [Background technology]

[0002] One of the self-defense tools used against thugs and other suspicious individuals is a saragata, which is a rod with the tip spread out in two directions. Recently, saragata have been placed in schools and various facilities as a precaution against intruders and suspicious people. The need for such self-defense tools against suspicious individuals is also growing in railway-related facilities, and installation in train stations and inside train cars is being considered. In this regard, Patent Document 1 below discloses an invention in which a saragata placed in train stations is configured to function as a ladder. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-017077 Summary of the Invention [Problem to be solved by the invention]

[0004] However, while there are various places to keep self-defense equipment such as saragata inside trains, it is not possible to place equipment boxes inside trains, nor is it possible to attach the self-defense equipment itself to the side of the train or under the seats, for example. Therefore, if a suspicious person such as a thug appears on a train while it is moving, the current practice is to make an emergency stop at the nearest station, and then station staff or others can confront the suspicious person with a saragata. However, if it takes a long time for the train to stop at the nearest station, it is necessary to protect oneself inside the train, and so the installation of self-defense equipment on trains is desirable.

[0005] SUMMARY OF THE INVENTION In order to solve this problem, an object of the present invention is to provide a railway vehicle equipped with handrails inside the vehicle that also serve as self-defense tools. [Means for solving the problem]

[0006] The railway vehicle of the present invention comprises a self-defense handrail member having a rod-shaped handle portion with one end to be held by the handle and a pressing portion that branches in two directions from the other end of the handle portion, and a fixing structure that removably fixes the self-defense handrail member in a position inside the vehicle where it can be used as a handrail. [Effects of the Invention]

[0007] According to the above configuration, when the self-defense handrail member is fixed inside the vehicle, it can be used as a handrail, and when a suspicious person such as a thug appears inside the vehicle, the self-defense handrail member can be removed, one end of the rod-shaped handle portion can be held as the handle side, and the pressing portion that splits into two directions on the other end of the handle portion can be pointed at the suspicious person and used as a self-defense tool like a sagittarius.

[0009] An embodiment of a railway vehicle according to the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a portion of the interior of the railway vehicle of this embodiment. Seats in railway vehicles include long seats in which the seated passenger faces in the width direction of the car body (sleeper direction) and cross seats in which the seated passenger faces in the fore-and-aft direction of the car body (rail direction). In this embodiment, a railway vehicle 1 equipped with a long seat 3 will be described as an example. The long seat 3 is a cantilever seat that protrudes from the side wall, and there is space under the seat, making it easy to clean the floor.

[0010] In railway vehicle 1, passenger entrances and exits are located on the sides of the car body, sandwiching long seats 3, and are provided with two passenger doors 11 that slide left and right. In addition, a connecting door 12 is provided on the end face of the car body in the fore-and-aft direction to separate the passageway between the cars. Incidentally, some trains made up of multiple railway cars may have free spaces at the ends of the car interior without seats, making it easier for wheelchairs and strollers to enter. Railway vehicle 1 is an example of such a vehicle, and a free space 4 is provided near passenger doors 11 near the end face.

[0011] Windows 13 and 14 are provided on the sides of the car body at the locations of the long seats 3 and the free space 4. Furthermore, a luggage rack 15 is provided above the long seats 3. This type of railway car 1 is a so-called commuter car, and the long seats 3 can seat a certain number of passengers, with passengers who are unable to find a seat having to stand in the aisle 5 in front of the seats 3 or in the free space 4.

[0012] Standing passengers may find it difficult to stand while the railway vehicle 1 is moving due to the swaying of the vehicle body. For this reason, handrails and handrails are provided in various locations inside the vehicle to enable passengers to support themselves in unstable conditions. Handrails are also provided to assist passengers who are using seats to stand up and sit down, and handrails are also provided to assist with moving around inside the vehicle while it is moving. In the railway vehicle 1 of this embodiment, the handrails provided in various locations are proposed to also function as self-defense tools.

[0013] Regarding self-defense equipment, some have suggested that existing items should be installed inside the vehicle. However, because commuter trains and other vehicles are used by many passengers, it is difficult to secure space to install a reasonably large item such as a sagami. For example, it could be placed in the space below the cantilevered long seat 3, but this is not an appropriate location due to issues such as it getting in the way when cleaning. Furthermore, because the railway vehicle 1 vibrates when in motion, it is not possible to install a sagami or other item inside the vehicle in an unstable state, and it is also necessary to prevent it from being used when not in use or being stolen.

[0014] On the other hand, as mentioned above, if a suspicious person such as a thug appears on board a moving train, self-defense equipment may be needed, and therefore it is desirable for passengers to have self-defense equipment such as a sarimata close at hand. Therefore, in the railway vehicle 1 of this embodiment, a handrail with the function of a self-defense equipment is proposed, which is something that passengers naturally use as part of the train interior at normal times, but can also be used as a self-defense equipment in an emergency.

[0015] The interior of the railway vehicle 1 shown in Fig. 1 has multiple vertical handrails and horizontal handrails. Specifically, stanchion poles 21, 22, and 23 are provided at predetermined positions in the longitudinal direction of the long seats 3. In addition, a stanchion pole 24 is provided in the center of the aisle 5 near the boarding / alighting entrance (boarding door 11) close to the free space 4, and handrails (vertical handrails or horizontal handrails) 25, 26, 27, and 28 that can be used as self-protection handrail members are also provided on the sides and end faces of the car body. Note that, of the stanchion poles 21, 22, 23, and 24, those attached to the luggage rack 15 and the frame 301 of the long seats 3 and whose lower sides are attached away from the floor 6 will be referred to as seat stanchion poles 21, 22, and 23, and those attached to the floor 6 inside the car and to the ceiling (not shown) will be referred to as floor-mounted stanchion poles 24.

[0016] Fig. 2 is a perspective view showing seat stanchion poles 21 and other components inside the vehicle, and Fig. 3 is a perspective view showing the seat stanchion poles 21 when removed. Note that a portion of the railway vehicle shown in Fig. 2 (the portion of the long seat 3) does not entirely match the railway vehicle 1 shown in Fig. 1. In this example, the long seat 3 is provided with a new seat stanchion pole 21 and a conventional seat stanchion pole 29. Also, the seat stanchion poles 23 located at the ends of the long seat 3 are not provided.

[0017] The seat stanchion poles 21, 29 are arranged so as to divide the seat of the long seat 3 into three sections. One of them, the conventional seat stanchion pole 29, is a single pipe curved so that it bulges toward the aisle 5, and is fixed to the luggage rack 15 and the frame 301 of the long seat 3. A T-shaped pipe joint 291 is fixed to the upper end of the seat stanchion pole 29, and is connected to the horizontal pipe 151 located at the forefront of the luggage rack 15 by passing through the horizontal cylindrical portion located at the tip. In addition, a bent portion 292 at the lower end extends to the frame 301 that supports the long seat 3, and is fixed via a mounting bracket (not shown).

[0018] On the other hand, the seat stanchion pole 21 of this embodiment is a self-defense handrail member that is an improvement on the conventional seat stanchion pole for self-defense purposes. Specifically, like the conventional ones, it is configured based on a single pipe that is curved so that it bulges toward the aisle 5. As shown in FIG. 3, the seat stanchion pole 21 has a curved, rod-shaped handle portion 31 at one end thereof, which is provided with a connecting fitting 32 that connects to the horizontal pipe 151 of the luggage rack 15. In addition, a pressing portion 33 that branches in two directions is formed at the other end of the handle portion 31.

[0019] The seat stanchion pole 21 has a handle on the side of the connecting metal fitting 32 of the handle portion 31, and a pressing portion 33 for holding down an object attached to the tip of a bent portion 311 on the opposite side. The pressing portion 33 is U-shaped and includes a straight portion 101 perpendicular to the handle portion 31 and restraining portions 102, 102 bent at approximately 90 degrees at both ends. When the seat stanchion pole 21 is installed inside the vehicle, as shown in FIG. 2, the restraining portions 102, 102 protrude in a direction that will enter the underside of the seat portion 303. In other words, the restraining portions 102, 102 are formed to protrude in the same direction as the bent portion 311 of the handle portion 31. Note that the shape of the stanchion pole may be such that the handle portion 31 is linear, or the pressing portion 33 may be arc-shaped.

[0020] With this shape, the seat stanchion pole 21 installed inside the vehicle is designed so that the newly added pressing portion 33 does not impair the comfort of passengers sitting on the long seats 3. The seat stanchion pole 21 can be used as a self-defense tool when removed, but when installed inside the vehicle, it performs the same function as a normal vertical handrail (seat stanchion pole 29). Therefore, the seat stanchion pole 21 needs to be equipped with a fixing structure that allows it to be removed in an emergency while maintaining the state of the vertical handrail under normal circumstances. Figures 4 and 5 show this fixing structure.

[0021] First, Figure 4 is a side view showing type (A) and type (B) of the upper fixing structure of the seat stanchion pole 21. The upper fixing structure is configured to be easily detachable by simply hooking the connecting fittings 32 (32A, 32B) of the seat stanchion pole 21 onto the horizontal pipe 151 of the luggage rack 15. The connecting fittings 32A, 32B have cylindrical members 321, 322 that fit onto the end of the handle portion 31 and are fixed together by screws or the like. The cylindrical members 321, 322 are each joined to a curved backing plate 333 or 334 that matches the outer diameter of the horizontal pipe 151 on the non-fitting side, forming an integral unit.

[0022] A conical protrusion 335 or 336 with a spherical top is joined to and integrated with the backing plates 333 and 334. The conical protrusions 335 and 336 are fitted into fitting holes 501 and 502 formed in the horizontal pipe 151. The conical protrusions 335 and 336 are formed with a diameter large enough to fit into the fitting holes 501 and 502 with almost no gap, and are formed so that there is no play when they are fixed in the state shown by the dashed dotted line.

[0023] Connecting fitting 32A is a type that is fitted from below, with fitting hole 501 formed below center position O of horizontal pipe 151. Connecting fitting 32B, on the other hand, is a type that is fitted from above, with fitting hole 502 formed above center position O of horizontal pipe 151. For this reason, as shown in the figure, backing plate 334 of connecting fitting 32B is formed larger and has a curved surface that grips horizontal pipe 151 from above on the front side (passage 5 side). On the other hand, backing plate 333 of connecting fitting 32A is small and has a curved surface that contacts horizontal pipe 151 from below on the front side (passage 5 side).

[0024] Next, Figure 5 is a perspective view showing the lower fixing structure of the seat stanchion pole 21, showing (A) the removed state and (B) the fixed state. The long seat 3 has a frame 301 that protrudes at a predetermined height from the side of the car body toward the aisle 5 (the inside of the car toward the sleepers), and above that is a seat consisting of a seat portion 303 and a back portion 304, with a cushioning material such as urethane covered with a fabric such as moquette. The lower fixing structure has a support block 35 fixed to the frame 301 of the long seat 3, and the seat stanchion pole 21 is supported by this support block 35 while being detachable. Note that, because the seat stanchion pole 21 serves to separate the seats of the long seat 3, the support block 35 is positioned along the dividing line 305 between adjacent seats.

[0025] The support block 35 is a rod member with a rectangular cross section whose long side is arranged vertically, and is fixed in a cantilevered state from the frame 301 in the sleeper direction. The support block 35 is designed to hold the pressing portion 33 side of the seat stanchion pole 21 at its tip. At the tip of the support block 35, a jaw portion protrudes from the lower part toward the inside of the vehicle, and the base of the jaw portion is formed in an arc shape to match the shape of the pressing portion 33, and a receiving portion 351 is formed that is cut into an L-shape in side view (viewed in the vehicle body longitudinal direction), and a fixing cover 36 is rotatably attached to the tip of the protruding jaw portion by a horizontal pin 41 (see Figure 6) arranged in the vehicle body longitudinal direction.

[0026] The fixed cover 36 restrains the T-shaped portion where the handle portion 31 and the pressing portion 33 of the seat stanchion pole 21 are joined, at the support block 35. Therefore, in the closed state shown in FIG. 5(B), the fixed cover 36 is formed in an inverted L-shape so that there is a gap between the receiving portion 351 and the fixed cover 36, through which the pressing portion 33 (straight portion 101) of the seat stanchion pole 21 passes. Furthermore, the fixed cover 36 is bifurcated so as not to interfere with the handle portion 31 (folded portion 311) of the seat stanchion pole 21. Therefore, when the fixed cover 36 is in the closed state, the T-shaped portion of the seat stanchion pole 21 is restrained, and movement in the width direction, fore-and-aft direction, and up-and-down directions of the vehicle body is restricted, and the seat stanchion pole 21 functions as a vertical handrail inside the vehicle.

[0027] The fixed structure of the seat stanchion pole 21 is maintained in a fixed state by the lower fixed cover 36, so the closed state shown in FIG. 5(B) must be stable. Therefore, a strong magnet is used for the fixed cover 36, and a hook lock is provided between the support block 35 and the fixed cover 36, so that the closed state of the fixed cover 36 is normally stable. However, in railway vehicles that carry an unspecified number of passengers, it is also necessary to consider preventing tampering. Therefore, it is necessary to make it so that the fixed cover 36 cannot be easily removed except in an emergency. Therefore, in this embodiment, a fixing structure is used in which an electromagnetic lock is attached to the fixed cover.

[0028] 6 is a partial cross-sectional view of the lower fixing structure of the seat stanchion pole 21, with an electromagnetic locking mechanism added, showing a side view (A) and a plan view (B). (A) is a view taken from the position of the arrow DD in (B). Similar to the fixing structure described above, a support block 37 is fixed to the frame 301 of the long seat 3, and a fixed cover 38 is pivotally attached thereto by a horizontal pin 41. An L-shaped receiving portion 371 is formed at the tip of the support block 37, and the fixed cover 38 is formed to have an inverted L-shape. Therefore, when the fixed cover 38 is closed, the pressing portion 33 (straight portion 101) of the seat stanchion pole 21 passes through between the receiving portion 371 and the fixed cover 38.

[0029] Furthermore, a step 372 is formed on the upper side of the receiving portion 371 of the support block 37, into which the tip of the fixed cover 38 fits. A through hole 381 parallel to the horizontal pin 41 serving as the center of rotation is formed in the bifurcated fixed cover 38 at the portion overlapping one of the step portions 372, and a stop hole 375 is formed in the step portion 372 so as to communicate with the through hole 381. An electromagnetic lock 39 is fixed by a bracket 42 to the side surface on which the through hole 381 and other parts are formed.

[0030] In the electromagnetic lock 39, a lock pin 43 integral with the plunger is biased by a spring in a direction that causes it to protrude from the main body toward the through-hole 381. When a current is applied to a coil inside the main body, the plunger is attracted to the fixed iron core, and the lock pin 43 is drawn toward the main body against the biasing force of the spring. Therefore, when not energized, the lock pin 43 is inserted through the through-hole 381 and into the stop hole 375, as shown in FIG. 6(B), and when energized, it comes out of the through-hole 381.

[0031] This electromagnetic lock 39 has a lock release button that is installed in a predetermined position in the driver's seat or cab of the train, which unlocks the lock when powered on. In the event of an emergency, passengers can press the emergency button inside the train, enabling communication between the inside of the car and the cab. This triggers a crew member, such as the driver or conductor, to operate the lock release button.

[0032] Therefore, in the railway vehicle 1 of this embodiment, the seat stanchion pole 21 is normally used as a vertical handrail for passengers to support their bodies, but in an emergency when it is necessary to deal with a suspicious person such as a thug inside the vehicle, it can also be used as a self-defense tool like a sagittarius. Normally, as shown in Figure 6, the fixed cover 38 is immobilized by the electromagnetic lock 39, and the lower side of the seat stanchion pole 21 is restrained, and the upper connecting metal fittings 32A, 32B are kept in a state in which they are hung on the horizontal pipe 151 with the conical protrusions 335, 336 fitted in. Furthermore, the seat stanchion pole 21 is normally designed to be inconspicuous as a self-defense tool, so it does not impart a psychological sense of oppression to passengers.

[0033] When the solenoid of the electromagnetic lock 39 is energized, the lock is released and the seat stanchion pole 21 can be removed as shown in Figure 3. For example, when confronting a violent person carrying a weapon, the seat stanchion pole 21 can be held with the pressing portion 33 facing the violent person to prevent them from approaching. In addition, the seat stanchion pole 21 can stop the violent person's movement from a distance by placing the body of the fallen violent person between the restraining portions 102, 102 and holding him down against the floor 6.

[0034] 7 and 8 show modified examples of seat stanchion poles, with Fig. 7 being a perspective view of the seat stanchion pole and Fig. 8 being a side view showing the seat stanchion pole in its installed state. This seat stanchion pole 50, like the previous example, has a curved, rod-shaped handle portion 51 to which a connecting fitting 52 is fixed at one end, and a U-shaped pressing portion 53 that branches in two directions is formed at the other end. However, the bifurcated pressing portion 53 has left and right restraining portions 105, 105 facing the longitudinal direction of the handle portion 51.

[0035] Therefore, when the seat stanchion pole 50 is attached to the luggage rack 15 and the frame 301 of the long seat 3 as shown in Figure 8, the restraining portions 105, 105 are oriented perpendicular to the floor 6. However, since the pressing portion 53 is located behind the legs of a passenger sitting on the long seat 3, it does not get in the way when sitting in a normal position. Furthermore, the seat stanchion pole 50 has a handle 55 joined to the handle portion 51. The handle 55 is located at the end on the connecting fitting 52 side, which is the handle side, and is normally located near the luggage rack 15.

[0036] Therefore, while the seat stanchion pole 50 is normally used as a vertical handrail for passengers to support their bodies, it can also be used as a self-defense tool like a sagami-mat (a cross-legged stomp) against a suspicious individual such as a thug who appears inside the vehicle. In particular, since the restraining portions 105, 105 face forward when held, it can restrain the thug's body and pin him down against a wall or other surface, just like a regular sagami-mat. The seat stanchion pole 50 is provided with a handle 55, making it easy to apply force when held and easy to operate. Meanwhile, when installed inside the vehicle as shown in Figure 8, it is possible to respond to shaking by grasping not only the handle portion 51 but also the handle 55.

[0037] Although one embodiment of the present invention has been described above, the present invention is not limited to this and various modifications are possible without departing from the spirit of the present invention. In the above embodiment, a specific example of a seat stanchion pole was explained, but the floor-mounted stanchion pole 24 and the handrails 25, 26, 27, and 28 can also be used as self-defense devices by providing a removable fixing structure. For example, a fixing structure can be created by incorporating an electromagnetic lock consisting of a solenoid as shown in Figure 6 under the floor, in the ceiling, or behind the wall.
