Abstract

PROBLEM TO BE SOLVED: To prevent water droplets from dripping onto an indoor floor face when an inward- swinging door, in which one side is supported by a hinge, is opened and closed by installing a gutter lowered towards the hinge side to the lower section of the door and forming a drain inlet on the hinge side of the indoor floor face. SOLUTION: The inward-swinging door 4 is mounted in the entrance/exit 3 of a driver's cab 2 for a railway rolling stock in a manner that the door 4 can be opened and closed while one side is supported by hinges 5, 5. A gutter 6 lowered towards the hinges 5, 5 sides is set up to the lower section of the external surface of the inward-swinging door 4. A sump 8 is formed extendedly over approximately the overall length of the entrance 3 to the indoor floor face 7 of the entrance 3, and drain inlets 9, 9 discharging water to the outside of a car are formed to the hinges 5, 5 sides and opening side of the sump 8 respectively. According to such constitution, even when the inward-swinging door 4 is opened and closed, water droplets adhering on the external surface of the inward-swinging door 4 are collected to the gutter 6, fall into the sump 8 from the end sections of the hinges 5, 5 sides of the gutter 6, and discharged to the outside of the car from the drain inlets 9, 9. Consequently, water droplets do not fall off to the indoor floor face 7, and the indoor floor face 7 is not moistened.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage structure for an entrance having an inward opening door provided in a vehicle or a machine.

[0002]

2. Description of the Related Art In a doorway having an inward opening door provided in a vehicle or a machine used outdoors, water droplets adhere to the outer surface of the door on a rainy day. It wasn't.

[0003]

For this reason, water droplets attached by opening and closing the door are dripped into a vehicle room or a machine room.
There is a problem that the indoor floor surface gets wet.

Accordingly, an object of the present invention is to provide a drainage structure for an entrance having an inward opening door in which water drops do not drop onto the floor of the room even when the door is opened and closed.

[0005]

In order to achieve the above-mentioned object, a drainage structure for an entrance having an inner opening door according to the present invention is provided at the entrance having an inner opening door whose one side is supported by an elbow. A lower gutter is provided on the lower side of the inner opening door, and a drain port is formed on the lower side of the indoor floor.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention applied to entrances and exits of railway vehicles will be described in more detail with reference to the drawings.

FIGS. 1 and 2 show a first embodiment of the present invention.
An inward opening door 4 is provided so as to be openable and closable, with one side supported by the tongues 5 and 5. A lower part of the outer surface of the inward opening door 4 is provided with a gutter 6 which becomes lower on the side of the tine 5.
On the indoor floor 7 of the entrance 3, a water reservoir 8 is provided over substantially the entire length of the entrance 3, and
Drainage outlets 9 and 9 for discharging to the outside of the vehicle on the 5 side and the open side respectively
Are formed.

With this configuration, even when the inner door 4 is opened and closed, water droplets attached to the outer surface of the inner door 4
The water is collected in the gutter 6 and the water pool 8
, And is discharged out of the vehicle through the drain ports 9 and 9. Therefore, water drops do not drip on the indoor floor 7 and do not wet the indoor floor 7.

In FIG. 3, a slit 11 is formed in the lower part of the outer surface of the inner opening door 10 so as to extend over almost the entire width of the inner opening door 10, and an inclined plate 12 is provided at the lower end of the inner opening door 10 to be lowered toward the hinge. A gutter 15 is formed by the outer plate 13 and the inner plate
5 shows a second embodiment of the present invention in which a drain port 16 is provided at the end of the hinge side, and a drain port 17 is formed on the indoor floor surface below the drain port 16. The adhering water droplets pass through the slit 11, the inclined plate 12, the outer plate 13, and the inner plate 1.
4 and are discharged from the drainage port 16 to the outside of the vehicle through the drainage port 17.

In the above embodiment, the present invention has been described as applied to the entrance of a railway car, but the present invention can be applied to machines and devices used outdoors.

[0011]

As described above, the drainage structure for an entrance having an inward opening door according to the present invention is provided with a lower gutter on the lower part of the inner opening door and a drainage on the floor of the room on the upper side. Since the mouth is formed, even if the inward opening door is opened and closed, water droplets adhering to the outer surface of the inward opening door are collected in the gutter and discharged from the end of the gutter on the side of the sheave through the drain port to the outside of the vehicle. Therefore,
Water drops do not drip on the indoor floor, and the indoor floor is not wetted.
