Description

  The present invention relates to an entrance / exit side structure of a transportation facility having a grip portion on the side of an entrance / exit of a transportation facility such as a railway vehicle or a bus.

As an entrance / exit side structure of such a transportation system such as a vehicle, the present applicant has previously provided a grip member that also serves as an inner column on the entrance / exit side of a railway vehicle or the like as an improvement of the door pocket structure. (See Patent Document 1). As shown in FIG. 9, this structure simplifies the door pocket structure by providing a gripping member c that also serves as an inner column that receives the end portion of the door inner wall b on the side of the vehicle doorway a. Therefore, as shown in FIGS. 7 and 8, the gripping member c has a thickness at the front end portion of the column plate e extending from the attachment base portion d to the inner wall b of the door pocket and facing the entrance / exit side of the vehicle. A grip portion f having a large diameter is also provided. As a result, the columnar plate e supports the door pocket with sufficient strength by a bent or curved projecting shape as shown in FIGS. 7 and 8 toward the inside of the vehicle, and at the same time, reaches the gripping portion f facing the opposite exit side. The entrance / exit face g is formed to prevent the passenger from getting caught or collided with the gripping part or the baggage, and the gripping part f is used for holding the passenger and can be secured.

  However, the gripping portion f provided subsequent to the tip of the columnar plate e is sufficiently large with respect to the thickness of the columnar plate e as shown in FIGS. There is a feeling of being hard to grasp. As a result of repeated examinations by the inventor in various experiments, the inventor found that the pillar plate e was obstructed and the hand holding the grip part was not closed and could not be clamped, and this was solved. I found a possible improvement.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a safer entrance / exit side structure for transportation that can firmly grip a gripping portion without impairing the advantages of a gripping member that also serves as an inner pillar.

In order to achieve the above object, the vehicle doorway structure according to the present invention is a transportation doorway structure in which a gripping member that also serves as an inner pillar is provided on the vehicle doorway side. In the vicinity of the tip of the pillar plate extending from the inside to the transportation, a grip portion is provided with a grip window that leaves a plurality of connecting portions between the pillar plate and the pillar plate is an integrally formed member. It has a notch processing part that leaves a plurality of communication parts with the grip part, and a bar-shaped grip part is attached to the plurality of connection parts to form a window for gripping with the notch processing part between the pillar plate It is characterized by that.

In such a configuration, as in the case of the previous gripping member, sufficient support strength as an inner column on the side of the entrance / exit is secured by the protruding shape of the columnar plate having a gripping portion at the tip to the inside of the transportation system. By forming the entrance / exit surface to the gripping part by the gripping part, the gripping part can be gripped and tightened by opening the entire periphery of the gripping part by a gripping window held between the gripping part and the pillar plate. In particular, a gripping member having a window for gripping can be obtained simply by notching the remaining portion of the pillar plate, which is an integrally formed member, so as to leave a connection portion with the gripping portion and attaching the gripping portion to the formed connecting portion.

According to the entrance / exit side structure of the transportation system of the present invention, the protruding shape of the pillar plate ensures sufficient support strength as an inner pillar beside the entrance / exit, and forms an entrance / exit surface that the pillar plate extends to the gripping part. It is possible to increase the safety of passengers by increasing the gripping part through the window for gripping between the pillar plate and the gripping part while avoiding the catching part or the luggage being caught or hitting the gripping part. In particular, the gripping member can be obtained at low cost simply by notching the tip of the column plate, which is an integrally formed member, and attaching the gripping part to the connecting part left by the notching by screwing or welding.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a vehicle doorway side structure according to the present invention will be specifically described with reference to FIGS. The following description is a specific example of the present invention and does not limit the content of the claims.

  The present embodiment is an example when applied to the entrance / exit of a railway vehicle, specifically, the entrance / exit of a side structure, and the entrance / exit of a wife structure, and examples shown in FIGS. 1 and 2 and examples shown in FIGS. As shown in FIGS. 3 and 4, in the vehicle entrance / exit side structure in which the gripping member 3 that also serves as an inner pillar is provided on the side of the entrance / exit 2 such as the side of the vehicle 1, the gripping member 3 is disposed from the side of the entrance / exit 2 to the vehicle. Assume that a grip portion 3d is provided in the vicinity of the tip portion of the pillar plate 3a extending inward, specifically, at the tip portion with a grip window 3c that leaves a plurality of connecting portions 3b between the pillar plate 3a. Yes. In this way, for example, like the previous gripping member, the gripping member 3 protrudes from the attachment base 3e to the inner plate 4 made of plywood or the like in the door pocket structure of the sliding door 5, for example, and has the gripping portion 3d. The bent shape shown in FIGS. 1 and 4 or the curved shape shown in FIG. 2 and FIG. Secure support strength, and by using the pillar plate 3a to form a doorway surface 3f that extends to the gripping portion 3d that faces the doorway side, passengers and luggage are caught or hit by the gripping portion 3d. While preventing, the gripper 3d opens between the entire periphery of the gripping part 3d by the gripping window 3c held between the pillar plate 3a and closes the fingers so that it can be firmly gripped. , Of the passengers safety can be achieved by ever before.

  However, the doorway 2 has a plug door structure that does not require a door pocket structure, and is not constant. For reasons such as the difference in the door structure, the presence or absence of the door pocket structure, and other reasons, the vehicle 1 of the pillar plate 3a of the gripping member 3 The direction of the overhang may be directed to the opposite side of the examples of FIGS. 1 and 4 or the examples of FIGS. 2 and 5, and the direction and shape of the overhang can be variously selected. Moreover, the part attached or fixed to the part of the entrance / exit 2 can also be designed variously according to the other party's structure and shape.

  Such a gripping member 3 can be made of metal or resin, and can contribute to weight reduction of the vehicle by being made of aluminum or resin. If it is made of stainless steel, strength, durability and aesthetics are enhanced. . When the extruded shape is made of aluminum, various cross-sectional shapes can be easily obtained.

In the example shown in FIGS. 1 and 2, since the column plate 3a and the grip portion 3d are formed of an integrally formed member, the grip window 3c is formed as a drilling portion 3g. In particular, the integrally molded member is an extruded shape, and a window for gripping can be obtained simply by drilling the extruded shape with a cross-sectional shape having a column plate 3a and a gripping portion 3d by a cutting method with a smooth cutting surface such as laser processing. The gripping member 3 having 3c can be obtained at low cost, and finishing can be omitted or reduced depending on the smoothness of the cut surface. If the integrally molded member is a molded product made of a resin member or the like, it can be obtained without punching by molding, and is particularly effective for cost reduction by mass production. The necessary contour shape, perforated shape, bent shape, and curved shape can be easily obtained by sheet metal processing, and the grip portion 3c can be formed into a pipe having a predetermined thickness by rounding using sheet metal. it can.

  In the example shown in FIGS. 4 and 5, the column plate 3a is an integrally formed member, and has, for example, a notch processing portion 3h by laser processing or the like that leaves a plurality of connecting portions 3b with the grip portion 3d at the tip portion. In addition, a bar-shaped grip portion 3d is attached to the plurality of connecting portions 3b by screwing or welding, and a grip window 3c is formed between the pillar plate 3a and the notched portion 3h. As a result, a notch process is made to leave a connecting part dg with the gripping part 3d at the tip of the pillar plate 3a which is an integrally molded member, and the gripping window 3c is simply attached to the connecting part 3b. The holding member 3 can be obtained at a low cost. Moreover, since the column plate 3a and the grip portion 3d are separate bodies, there is a degree of freedom in which both materials can be made different as necessary. However, in this case as well, the column plate 3a can be an extruded shape, and if it is a molded product, the notched portion 3h can be omitted as a molded portion. Moreover, if it is a sheet metal processed product, a necessary outline shape, bent shape, and curved shape can be easily obtained. Furthermore, various methods such as welding, screwing, and winding of the connecting portion 3b around the holding portion 3d can be adopted for attaching the holding portion 3d to the connecting portion 3b. it can.

  In either case, as shown in FIGS. 3 and 6, the holding member 3 extends vertically from the floor 6 of the vehicle 1 to the duck 7 as an inner pillar of the doorway structure of the vehicle, and protrudes toward the inside of the vehicle. The side design of the entrance / exit 2 is made clean while making the entrance / exit surface 3f following the grip portion 3d near the tip end facing the side to eliminate collisions of people and luggage, etc. It is possible to grasp the height position suitable for himself from a short person to a tall person in order to secure passenger safety with the grip part 3d near the front end part which protrudes to the inside of the car and faces the entrance / exit side. There are advantages. In order to prevent a person or a luggage from colliding with the grip portion 3d by the entrance / exit surface 3f formed by the column plate 3a, the grip window 3c is preferably as small as possible.

  Specifically, in the lateral direction, it is at least about 1/2 or less, preferably about 1/3 of the length of the column plate 3a extending to the grip portion 3d in the vehicle. In the example shown in the figure, the diameter of the circular grip portion 3d is about the same. Further, in the vertical direction, it is necessary to have at least a connecting portion 3b that secures the supporting strength of the grip portion 3d by the pillar plate 3a. However, if the occupation ratio in the vertical direction of the connecting portion 3b is increased, the grip portion 3d can be clamped. The area will be reduced. In the example shown in the figure, the connecting portions 3b are provided at the minimum and upper and lower widths at two locations on the upper and lower ends and two locations along the way.
