Description

  The present invention relates to a vehicle entrance / exit structure in which a service box is provided on a side of an entrance / exit and a grip bar is provided on a front surface of the service box.

  Most of the sightseeing buses have a boarding / exiting opening on a side surface in front of the vehicle, and lead to a vehicle interior passage extending in the front-rear direction of the vehicle from the boarding / exiting port through a step or the like. In the case of a sightseeing bus, a storage table called a service box is installed in front of the seat row arranged on the vehicle rear side of the step, that is, on the entrance / exit side, and stores drinks and equipment. is there.

  In addition, a tourist bus called a high-decker car with a passenger seat located high above the ground has a handrail (grip bar) attached to the wall of the service box so that passengers who go up and down steps can grip the grip bar. ing.

Japanese Patent No. 3470778 discloses an invention in which a handrail is extended outside the vehicle when the door is opened.
Japanese Patent No. 3470778

  Conventionally, since the service box and the partition plate were made of wood, they were basically formed in a rectangular parallelepiped shape and bent from the entrance / exit to the vehicle interior passage at a right angle. For this reason, passengers must bend at right angles every time they go back and forth between the entrance and exit of the passenger compartment and stop at the bent portion and change their direction.

  In addition, the drawer opening and the opening / closing lid provided in the service box are basically rectangular, and these are provided in front of the service box (to the vehicle) to which the grip bar should be attached. It was not possible to attach it diagonally. For example, in the past, a grip bar was provided below the step so that it did not interfere with the drawer of the service box or the lid, or the grip bar was divided into multiple parts. It was difficult.

  Furthermore, since the grip bar is directly attached to the service box or the like, the service box itself is required to have enough strength to withstand the load applied to the grip bar, and the wall thickness is increased or the size is increased. Therefore, the service box has a structure that is stronger than necessary as a storage base for storing drinks and fixtures.

  The present invention solves the above-mentioned problems, and passengers can smoothly go up and down the steps, and a handrail (grip bar) is continuously arranged from the entrance to the vehicle interior passage, and has a simple configuration and an excellent appearance. It is an object to provide a vehicle entrance / exit structure that can be further reduced in weight.

  In order to solve the above problems, the present invention has a vehicle entrance / exit structure configured as follows.

1. A doorway provided on the side of the front of the vehicle,

The vehicle entrance / exit structure according to any one of claims 5 and 3, wherein the wall located below the grip bar bulges in the width direction so as to be substantially flush with the outer edge of the grip bar, and the bulging portion is The storage part of the storage base was used.

  6. In the vehicle entrance / exit structure according to 6, 1, the stepping plate of the step is formed corresponding to the curvature of the wall body.

The vehicle entrance / exit structure according to the present invention has the following effects.
Since the grip bar is attached to the frame fixed to the vehicle body, a highly rigid grip bar is provided with a simple configuration. Since the load from the grip bar is hardly applied to the service box, the wall body can be formed of synthetic resin, can have a simple structure, and can be formed in an arbitrary shape, for example, an arc shape.

  The storage part provided in the service box can be formed in an arbitrary shape and position by forming with a synthetic resin. Therefore, a storage part can be formed according to a grip bar, and a grip bar can be provided in arbitrary shapes. Therefore, a continuous grip bar can be disposed in front of the service box along the step path.

  A gap can be arbitrarily formed between the grip bar and the outer wall of the service box, and the grip bar can be easily gripped. The wall body located below the grip bar is bulged outward, and the bulged portion can be effectively used as a storage portion. The outer surface of the grip bar and the outer wall surface of the service box located below the grip bar are substantially flush with each other, and the grip bar can be prevented from protruding from the outer wall of the service box.

  The grip bar can be provided without affecting the door drive mechanism. A step passage that is easy to move up and down can be formed.
