DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a double sliding door for a railway vehicle. For more details,
The present invention relates to a double sliding door for a rail vehicle that can be easily removed even if a hand, clothes, a strap of a handbag, or the like is caught when the side entrance for the rail vehicle is closed.

(Prior Art) In a railroad vehicle, particularly a railroad vehicle used as a commuter train in a large city and the suburbs of a large city, a side doorway provided on a side wall is a pair that moves in the direction of separation or approach along the side wall of the railcar. It is generally opened and closed by both sliding doors including the sliding door body.

Such two railroad vehicle sliding doors are provided with elastic members that are fixed to the opposite side end portions of the sliding door body and extend in the vertical direction. These elastic members are
That is, when the sliding doors are closest to each other, they will be in close contact with each other,
It is designed to prevent rain and wind from entering the vehicle.

In order to completely prevent the entry of rain and wind, the elastic members must have a shape in which they are in close contact with each other without a gap. As shown in FIGS. 4 to 6, elastic members having various cross-sectional shapes have been conventionally used. Both sliding doors provided are proposed.

4 to 6 are enlarged cross-sectional views of opposite ends of conventional double sliding doors, respectively. Here, a conventional double sliding door for a rail vehicle will be described with reference to FIGS. 4 to 6.

First, both sliding doors 50 shown in FIG. 4 are provided with a pair of sliding door bodies 51, 51 facing each other, and an elastic member 53 extending in the up-down direction is provided at an opposite side end portion 51a of each sliding door body 51. It is provided. The elastic member 53 includes a base portion 56 held by a groove portion 55 provided in the opposite end portion 51a and a buffer portion continuous with the base portion 56.
It consists of 57 and.

Elastic members fixed to the respective sliding door bodies 51 in this manner
The buffer portion 57 of 53 has a substantially semicircular cross section in which the front end surface 57b is curved, and further has a space S1 extending vertically in the interior thereof. Therefore, when the side entrance (not shown) is closed, the respective cushioning portions 57, 57 are deformed according to the direction in which the front end surfaces 57a, 57a are pressed when they come into contact with each other, and these 57a, 57a form a gap. It is designed to stick to each other.

Further, in the double sliding door 60 shown in FIG. 5, the elastic members 63, 64 arranged on the sliding door bodies 51, 51 facing each other are vertically arranged outside or inside the abutting point 68 on the front end face 57a. It has projections 66a and 66b extending over the entire length.

In such a sliding door 60, when the front end surfaces 57a, 57a contact each other at the contact point 68 when the side entrance (not shown) is closed,
Since the tips of 66a and 66b also come into contact with a part of the front end face 57a that faces them, the structure is more sealed than the conventional double sliding door 50 shown in FIG.

Further, in the double sliding door 70 shown in FIG. 6, the elastic member 76 arranged in the facing sliding door main body 51c has a protrusion 78 extending in the vertical direction at the center of the front end face 77. The elastic member 79 disposed in the other sliding door body 51d has a pair of protrusions 81 extending in the up-down direction at both end edges of the front end face 80.
It is a hollow body having 81.

Such a double sliding door 70, when the side entrance (not shown) is closed,
The protrusions 78 and the tips of the protrusions 81, 81 come into contact with a part of the front end faces 80, 77 facing each other, and at this time, the elastic member 79 is slightly deformed according to the pressing direction. ,
It is possible to prevent the formation of a gap between 79.

(Problems to be solved by the invention) By the way, especially in a big city and the suburbs of a big city, congestion at the time of commuting is so great that when the side entrance is blocked, the hand, clothes, or hand bag of a person on the car or platform is blocked. Often, a strap or the like is sandwiched between elastic members.

When a railway vehicle is started in such a state, an accident is likely to occur.Before starting the railway vehicle, open the sliding door body manually or deform the elastic member to create a gap, It is necessary to pull out the strap of the handbag from this gap.

However, the sliding door body is driven by an air cylinder by compressed air, an electric motor, a lever, etc., and when the side entrance and exit are closed, the abutting elastic members are normally pressed against each other with a large pressing force of 40 to 60 Kgf. Therefore, it is very difficult to open the sliding door main body manually to form a gap between the elastic members and pull out the object sandwiched from the gap.

Also, as shown in FIGS. 4 and 5, double sliding doors 50,
In the case of 60, the elastic members 53, 63 are provided by directly applying an external force from the outside A or inside the railway B of the railway vehicle with a hand or by indirectly pulling the sandwiched object to apply the external force. Even if you try to deform 64 to make a gap, the width of the elastic member is 15 ~
It is as narrow as 20 mm and difficult to deform.

Further, in particular, the double sliding door 60 as shown in FIG. 5 has a problem that it is easy to bit an object because the front end face 57a has the projections 66a and 66b.

In the double sliding door 70 as shown in FIG. 6, one elastic member
Since 79 is a hollow body, the object sandwiched between the elastic members 76 and 79 can be pulled out by deforming the elastic member 79. However, in this double sliding door 70, the other elastic member
Since 76 is a solid body, it is difficult to deform and the end face 77a
Since the central portion is provided with the protrusion 78, there is a problem that an object to be pulled out is easily caught by the elastic member 76.

The present invention has been made to solve the problems of the related art, and it is easily deformed to form a gap by directly or externally applying an external force by pulling a sandwiched object. It is an object of the present invention to provide a double sliding door for a railway vehicle including an elastic member that can be used.

[Means for Solving the Problems] (Means for Solving the Problems) In order to achieve the above object, the present invention moves in a separating or approaching direction along a side wall of a railway vehicle to open and close a side entrance / exit for the vehicle.
