Description

  The present invention relates to a vehicle suspension position adjustment apparatus, and more particularly to a railway vehicle suspension position adjustment apparatus.

  In recent years, studies have been conducted on the position of a train suspension. In other words, it is desirable to arrange the suspension so that the feet of the passenger sitting in the seat (passenger in the sitting position) do not come into contact with the feet of the passenger standing in the suspension (passenger in the standing position).

Conventionally, when a short passenger such as a child or an elderly person uses it, the suspension hand is extended and lowered. A suspension hand that can return to the above has been proposed (see Patent Document 1 below).
JP 2001-71805 A

  However, in the conventional suspension described above, a belt winding mechanism is provided on one end side of the belt that suspends the suspension ring, and an engagement portion formed on the belt is engaged on the belt outlet side of the winding mechanism. A locking mechanism for stopping is provided, and the suspension ring is provided with a locking release mechanism for releasing the locking mechanism. The mechanism is complicated and there is a problem in terms of durability.

  It is also possible to adjust the distance to adjust the distance from the passenger in the sitting position. However, if the length of the suspension is increased, there is a problem that the vehicle becomes unstable when the vehicle shakes. It was.

  Furthermore, foreigners and young people generally have longer legs than elderly people and children, etc., and passengers with such long legs are sitting on the seat, and in the current state of suspension, Before that, there was a problem that the legs of the passengers in the standing position touched by the suspension hand or the passengers in the standing position stepped on the feet of the passengers in the sitting position.

  FIG. 8 is a schematic diagram showing the positions of a passenger in a sitting position, such as the conventional problem, a suspension hand, and a passenger in a standing position using the suspension hand.

  As shown in this figure, when a passenger 102 in a sitting position with a long leg is sitting on the seat 101, the passenger 104 in a standing position is grasped by a suspension hand 103 in front of the passenger 102 in the sitting position. The feet collide with the feet of the passenger 102 in the sitting position. In addition, since the position of the suspender is in front of the standing position, there is a problem that an unnatural posture must be taken and the position becomes unstable. On the other hand, for the passenger 102 in the sitting position, the passenger 104 in the standing position is approaching in front of the passenger 102, so that there is a problem that the sitting space is narrow and there is a feeling of pressure.

  In addition, when standing up, if the upper body is tilted forward and the buttocks are raised, the standing passenger 104 prevents this upper body from tilting forward. Is done. In addition, when standing with the upper body raised, there is a danger of bumping the head against the luggage rack.

  In view of the above situation, the present invention provides a vehicle suspension position adjustment device that eliminates the feeling of oppression of a passenger in a sitting position and can stably stand in a natural position. Objective.

In order to achieve the above object, the present invention provides
