Description

  The present invention relates to a movable holder for a rail vehicle and a rail vehicle including the same.

  Currently, a law (the so-called barrier-free law) on the facilitation of the movement of elderly people, persons with disabilities, etc. is being enforced, and as a result, public transportation vehicles for public transportation such as railway vehicles The Ministry of Land, Infrastructure, Transport and Tourism has set forth guidelines for facilitating transport and other matters.

  These guidelines include the dimensions of the slope and the angle during use to eliminate the gaps and steps between the platform and the railway vehicle, the open dimensions in the rail direction of the side sliding door of the railway vehicle, and the railroad vehicle. The size and installation position of a multi-purpose space (hereinafter referred to as a wheelchair space) and matters related to a display unit indicating these are stipulated.

  Furthermore, in consideration of elderly people, handicapped persons, short stature persons, children, etc., who are difficult to use conventional hanging hands, they are equipped with vertical handrails for standing posture support and clues for standing and sitting. In addition to the conventional suspension hand, an example including a second handrail with a lowered handrail height is introduced in the guideline. In this way, barrier-free public transportation including railroad vehicles meets the demands of modern society and is expected to be increasingly promoted in the future.

  For example, Patent Document 1 discloses that standing post groups 4 to 7 are arranged in front of priority seats of a railway vehicle in order to cope with the problem of protecting passengers who are dangerously compressed such as elderly people, pregnant women, children, and disabled people. A railway vehicle having a configuration in which a priority area is defined by arranging in a row in the longitudinal direction of the vehicle starting from the vicinity of the door is disclosed.
