Description

  The present invention relates to a railway vehicle that can alleviate the impact received by passengers in the event of a train collision, sudden stop, derailment, or the like.

  In a railway vehicle, the seat may be configured as a long seat along the longitudinal direction of the vehicle. As shown in FIG. 6, a sleeve partition 11 is provided at the end of the long seat in the longitudinal direction to partition the side entrance and passage of the vehicle and the long seat (stool) 10 (for example, a patent) (See Reference 1, etc.)

  By the way, a report from the Ministry of Land, Infrastructure, Transport and Tourism accident survey on JR West “Train derailment between Fukuchiyama Line Tsukaguchi Station and Amagasaki Station” that occurred on April 25, 2005 (June 28, 2007) ) Pointed out the possibility that “supporting the body with a sleeve divider (armrest) or handrail was effective in reducing human damage”, “3.11 Analysis on Survival Factors” In the case of “... long seats, it is desirable to provide equipment for supporting the body such as sleeves (armrests) and handrails in addition to the end portions thereof. ... ".

  In particular, “sleeve (sleeve) partition” means “... a part of the body when a passenger collides as much as possible, for example, a tubular handrail at the end of the long seat is a plate-like partition. The shape and material should be such that the impact force is difficult to concentrate on. (See, for example, Patent Documents 2 to 3).

Therefore, in order to comply with the reports of the Railway Accident Investigation Committee, in the case of a new railway vehicle that will be manufactured in the future, from the initial stage of the design, such as increasing the size of the sleeve divider and adopting an elastic structure, Are beginning to be considered and introduced.
Japanese Utility Model Publication No. 4-46936 JP 2004-216571 A JP 2004-42807 A

  However, such a configuration in which the sleeve partition is enlarged or the sleeve partition itself has elasticity has a complicated structure and may be difficult to apply to an existing vehicle, particularly in terms of installation space and cost. .

  In addition, depending on the purpose of use and knitting of the railway vehicle, the field of view in the longitudinal direction of the vehicle and the design in the vehicle are important, and it may be difficult to adopt a large sleeve divider.

  The present invention has been made to address the above-described problems, and facilitates safety at the time of a collision even in an existing vehicle without deteriorating the field of view in the longitudinal direction of the vehicle or the design in the vehicle. The purpose is to provide a railway vehicle that can be improved.

In order to achieve the above object, according to the first aspect of the present invention, there is provided a railway vehicle comprising a long seat disposed near a wall along a longitudinal direction of the vehicle. In addition, when receiving an impact exceeding a predetermined acceleration (for example, 98 m / s ² ) from the center side of the long seat toward the end portion, impact absorption that reduces the reaction force that a passenger sitting on the long seat receives from the sleeve partition A sleeve partition is provided.

  The present invention relates to a railway vehicle having a long seat disposed near a wall along the longitudinal direction of the vehicle, and a passenger's body at the time of a train collision or the like on a sleeve partition disposed at the vehicle longitudinal end of the long seat. By providing “impact absorbing means” for releasing the impact load generated by the sudden lateral movement of the vehicle in the seating outer direction, the safety of passengers seated in the long seat is improved.

  That is, according to the first aspect of the present invention, the impact load generated in the longitudinal direction of the long sheet (from the center side toward the end side) is absorbed at the end of the long sheet near the side doorway of the vehicle. By arranging the shock absorbing sleeve partition to alleviate the injury or injury caused by the passenger sitting on the long seat colliding with the sleeve partition even if an excessive impact due to vehicle collision or sudden deceleration occurs. Can be minimized. Therefore, the railway vehicle of the present invention can easily improve the safety at the time of a collision even if it is an existing vehicle without increasing the sleeve partition.

  Here, as a specific structure of the shock absorbing sleeve partition, when receiving an impact exceeding a predetermined acceleration from the long seat central side toward the end side, a portion in contact with the passenger is directed outward in the longitudinal direction of the long seat. A configuration including a deformation means for bending or curving can be suitably employed. (Claim 2)

  Similarly, as a specific structure of the shock absorbing sleeve partition, when receiving an impact exceeding a predetermined acceleration from the long seat center side to the end portion side, the portion in contact with the passenger is directed outward in the long seat longitudinal direction. It is also possible to employ a configuration that includes a deformation means for displacing. (Claim 3)

  These deformation means do not improve the attachment part (fixing part) to the long seat in the sleeve partition, and the deformation of the armrest part that is located above the seat (sitting) and touches the passenger while the base part is fixed・ It is intended to reduce the impact load on passengers due to displacement. With the above configuration, passengers sitting on long seats collide with sleeve dividers even when impacts caused by vehicle collision or sudden deceleration occur. Injuries and disabilities that occur can be minimized.

  In addition, as a structure of the said shock absorption sleeve partition, when the impact by a collision etc. is less than predetermined acceleration, it is desirable to provide the deformation | transformation suppression means which suppresses the action | operation of the deformation means of the said shock absorption sleeve partition. (Claim 4)

  This deformation suppression means is a configuration for preventing the shock absorbing sleeve partition from malfunctioning due to a load less than a predetermined acceleration due to acceleration / deceleration of the vehicle, etc. Inadvertent operation of the deformation means during normal operation can be prevented.

  In addition, this deformation | transformation suppression means is not a means to act | operate in parallel according to a load, but is a concept as what is called a limiter which act | operates only when a certain load or more is received. Therefore, it includes a configuration using a buckling member that buckles only when a predetermined acceleration is exceeded, but does not include a configuration that gradually deforms according to a load, such as a structure using an elastic member such as a spring.

  On the other hand, as a specific configuration to improve and absorb the impact load in the entire sleeve partition including the mounting portion by improving the attachment portion (fixed portion) to the long sheet in the sleeve partition, the long sleeve in the shock absorbing sleeve partition A slide means for moving the entire sleeve partition along the longitudinal direction of the vehicle is provided on the seat mounting portion, and the load that limits the movement of the sleeve partition at a load below the predetermined acceleration and exceeds the predetermined acceleration. The structure which provides the slide restriction | limiting means cancelled | released only when it receives can be employ | adopted suitably. (Claim 5)

  Also with the above configuration, it is possible to absorb and mitigate the impact when the passenger sitting on the long seat collides with the sleeve partition, and to reduce the injury and obstacle of the passenger due to the impact.

  The slide limiting means is not a means that operates in parallel according to the load, but is a concept as a so-called limiter that operates only when a certain load or more is applied, as in the case of the deformation suppressing means. Therefore, a configuration that gradually deforms according to a load, such as a configuration using an elastic member such as a spring, is not included.

  As described above, according to the railway vehicle of the present invention, safety at the time of a collision of a passenger sitting on a long seat can be improved without deteriorating the view in the longitudinal direction of the vehicle or the design in the vehicle. Further, the configuration of the present invention can be easily applied to existing railway vehicles.

The main structure is a metal frame 1c that is supported at regular intervals.

  Further, the sleeve partition unit 1 uses a part of the frame 1c positioned below the seat portion 10a of the long seat, using bolts on a mounting base (mounting bracket 10b) provided below the seat portion 10a. By attaching, it is fixed at a predetermined position at the end of the long sheet.

  The feature of the sleeve partition of the railway vehicle in this embodiment is that the side plates 1a and 1b are caused by a load applied to the seating side (side plate 1a side) near the center of the entrance / exit side (side plate 1b side) of the framework 1c that supports the side plates 1a and 1b. A space S that allows deformation is provided (deformation means). Further, in the space S provided in the framework 1c, when the load applied to the seating side is less than a predetermined value, the side plate 1a described above is stretched between the upper and lower members of the framework 1c constituting the space S. , 1b is disposed (a deformation suppressing means).

  The buckling member 1d has a substantially dumbbell shape having a constricted portion at the center, and is designed to buckle while reducing the length in the longitudinal direction when a load exceeding a predetermined acceleration is applied in the longitudinal direction. ing.

  Therefore, when a passenger sitting on the long seat collides with or leans against the sleeve partition due to a vehicle collision or sudden deceleration, and a load exceeding the predetermined acceleration is applied to the buckling member 1d, the buckling member 1d Bending is started, and the space S provided in the framework 1c on the entrance / exit side (side plate 1b side) is reduced, whereby the side plate 1a and the side plate 1b are bent or curved toward the outer side of the long sheet end (entrance entrance side). Will be.

  With the above configuration, the sleeve partition of the railway vehicle according to the present invention has a reaction force generated when a passenger sitting on a long seat collides with the sleeve partition even when an excessive impact caused by a vehicle collision or sudden deceleration occurs. Can alleviate passenger injury and injury.

(Deformation means). Also, between the movable portion 2c and the fixed portion 2b, as in the first embodiment, when the load applied to the seat is less than a predetermined value, the movable portion 2c and the fixed portion 2b are stretched between the movable portion 2c and the fixed portion 2b. Further, buckling members 2d and 2d for preventing sliding of the movable portion 2c are provided (deformation suppressing means).

  Even with the above configuration, when a passenger sitting on the long seat collides with or leans against the sleeve partition due to a vehicle collision or sudden deceleration, and a load exceeding a predetermined acceleration is applied to the seating side movable portion 2c, buckling occurs. When the members 2d and 2d start buckling and the distance between the movable portion 2c and the fixed portion 2b is reduced, the reaction force generated when the passenger collides with the sleeve partition can be absorbed and relaxed. Injury and injury can be reduced.

  In addition, although the buckling member 2d in this embodiment has also illustrated what was formed using the metal, the material and shape of this buckling member are not specifically limited like 1st Embodiment. What is necessary is just to form from what can comprise rigid bodies, such as hard resin.
