Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door type electric train door to which two window glasses, a window glass inside a vehicle and a window glass outside a company, are attached.

[0002]

2. Description of the Related Art FIG. 3 is a front view of a conventional train door viewed from the inside of a car, and FIG. 4 is an enlarged cross-sectional view taken along the line AA of FIG.

In FIG. 1, reference numeral 10 denotes a door body, which is formed by an inner plate 17 on the inside of the vehicle and an outer plate 18 on the outside of the vehicle.
Reference numeral 14 denotes a window provided on the door body 10 for attaching a window glass. Reference numeral 13 denotes a flange portion formed by overlapping and spot welding the inner plate 17 and the outer plate 18 around the window 14, and 12 denotes a concave step formed in the inner plate 17. The window glass 16 is provided with a sealing adhesive 15 on the concave step 12 and the flange 13.
The adhesive is fixed. The interior surface of the window glass 16 and the interior surface of the door body 10 are flush with each other, so that passengers in the vehicle do not accidentally get their fingers or hands between the window glass 16 and the door pocket. Has become.

The exterior surface of the window glass 16 and the door body 10
There is a step of about 20 mm between the outer surfaces of the vehicle, and the outer surface of the train door has a structure in which the window glass 16 is recessed. In addition, 19 is a door tip rubber and 20 is a door roller.

[0005]

SUMMARY OF THE INVENTION Conventional train doors are:
As described above, the interior surface of the window glass 16 and the door body 1
Since the inside surface of the vehicle 0 is flush, there is no risk that the passenger's finger or hand in the vehicle will be pinched between the door and the door pocket.

However, the conventional train door has a structure in which the window glass is recessed when viewed from the outside of the vehicle. Therefore, when a passenger trying to get on the train from the platform puts his finger or hand on the window glass. When the door is opened, there is a possibility that a finger or a hand may be caught between the window glass 16 and the door pocket. In fact, a "finger pinch" accident has occurred.

Further, since the window glass 16 has a partially concave structure, when washing the outer surface of the train with a car washer,
The tip of the rotary mop is difficult to reach the window glass surface. Therefore, the window glass cannot be cleaned cleanly.

Further, since the window glass 16 of the door is recessed, wind noise is generated at high speed, which is not preferable.

Further, since the window glass 16 is concave, the concave and convex of the door and the window glass 16 are greatly exposed on the outer surface of the vehicle, and the aesthetic appearance on the outer surface of the train is impaired, which is not preferable. .

The present invention has been made to solve such a conventional problem, and there is a possibility that a passenger may be caught between a door and a door pocket by a finger or a hand not only inside the vehicle but also outside the vehicle. It is an object of the present invention to provide a train door that can be cleanly cleaned with a rotary mop, and improves the appearance of a train.

[0011]

SUMMARY OF THE INVENTION A train door provided by the present invention comprises a door body provided with a window for mounting a window glass, and a vehicle interior and a vehicle exterior attached to the window at regular intervals. A sliding door type train door composed of a plurality of window glasses, wherein an interior surface of the interior window glass and an interior surface of the door body are flush with each other, and The exterior surface of the door body is the same surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings by way of examples.

(Embodiment 1) FIG. 1 is a sectional view showing a window structure of a train door according to Embodiment 1 and corresponds to FIG.

In FIG. 1, reference numeral 1 denotes a door body, which is formed by an inner plate 7 on the inside of the vehicle and an outer plate 8 on the outside of the vehicle. Both the inner and outer plates are made of stainless steel. Reference numeral 4 denotes a window provided on the door body 1 for attaching a window glass. Reference numeral 3 denotes a flange formed by superposing the inner plate 7 and the outer plate 8 around the window 4 and performing spot welding. 2a and 2b are concave steps formed by the inner plate 7 and the outer plate 8 on both sides of the flange portion 3, respectively.
The depths of the concave steps 2a and 2b are substantially the same, and the flange 3 is formed substantially at the center of the door body 1 in the thickness direction.

Reference numeral 6a denotes a window glass on the inside of the vehicle, and 6b denotes a window glass on the outside of the vehicle. The window glass 6a is adhesively fixed to the flange portion 3 and the concave step portion 2a by a seal adhesive 5a, and the window glass 6b is adhesively fixed to the flange portion 3 and the concave step portion 2b by a seal adhesive 5b. I have.

When the window glasses 6a and 6b are attached to the door body 1, the inner surface of the window glass 6a and the inner surface of the door body 1 are flush with each other.
And the outer surface of the door body 1 are flush with each other.

As the seal adhesives 5a and 5b, those having a property capable of absorbing the distortion even when the door is distorted and preventing the window glass from breaking or peeling are suitable, and have good weather resistance. Rubber, urethane resin or elastic epoxy resin is suitable. The thickness of the sealing adhesive that can absorb the distortion and is preferable for fixing the window glass is about 5 mm.

Reference numeral 9 denotes a dam, which is disposed between the flange portion 3 and the window glasses 6a, 6b so as to prevent the flowable seal adhesive from flowing out when the seal adhesives 5a, 5b are applied. I have. The material is preferably a flexible material such as rubber or soft plastic.

(Embodiment 2) FIG. 2 is a sectional view showing a window structure of a train door according to Embodiment 2 and corresponds to FIG.

In this embodiment, the inner plate 7 in the first embodiment,
Alternatively, this is an example in which melamine decorative plates 7a and 8a that cannot be bent are used in place of the outer plate 8. Melamine decorative board 7
Since the flange portions 3a and 8a cannot be formed by the bending process as in the first embodiment, a window frame F having a T-shaped cross section is used as an alternative. The window frame F
It can be manufactured as an extruded aluminum material or by bending a stainless steel plate.

The window glasses 6a and 6b are bonded and fixed to the window frame F with seal adhesives 5a and 5b.
In the fixed state, the window glass 6a and the inside surface of the door body 1 are flush with each other, and the window glass 6b and the outside surface of the door body 1 are flush with each other. In the second embodiment,
There is a slight step between the window frame F and the inner and outer plates 7a, 8a. The “same surface” in the present invention is a concept including a case where there is such a level difference.

[0022]

As described above, according to the train door of the present invention, the following configuration (1)
The effects of (3) are achieved.

(1) There is no danger of passengers being caught between the door and the door pocket by fingers or hands not only inside the vehicle but also outside the vehicle.

(2) When washing the outer surface of the train with a car washer, the tip of the rotary mop reaches, so that the window glass can be cleaned neatly.

(3) Since the window glass of the door is not dented, the appearance on the outer surface of the train is improved.
