Abstract

<P>PROBLEM TO BE SOLVED: To improve a side opening door device provided at a doorway of a crew's room or the like in an airtight vehicle such as Shinkansen railway. <P>SOLUTION: This side opening door device 100, used for opening and closing an opening section leading to the crew's room or the like, is provided in the body of the airtight vehicle 10. The side opening door device 100, including an inward-opening door 110 supported by a hinge, is opened and closed with a handle. The peripheral edge of the opening of the body mounts an expansive sealing rubber 300 sandwiched by the peripheral edge 112 of the door. When the door 110 is closed and the vehicle passes a revised point or a vehicle speed reaches a predetermined value, an air supply circuit opens, so that the expansive sealing rubber 300 expands to form a seal. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a side opening device in a railway vehicle.

Shinkansen vehicles and the like have a structure in which the passenger compartment is kept airtight when traveling, and fluctuations in external atmospheric pressure do not affect passengers.
The door of the passenger entrance / exit has a sliding door structure, and when the door is closed, the door is pressed to realize an airtight structure.
The leading vehicle is provided with an entrance to a driver's cab (conveyor compartment) separately from the entrance for passengers, and is equipped with an inner opening side opening device (hinge door).

In this side opening device, air is fed into an inflatable seal rubber disposed between the hinge door body and the vehicle body at a position where the hinge door main body is closed to form a seal structure.
In the conventional side opening device, when it is desired to manually operate the knob of the door body, the valve of the air circuit interlocked with the knob is mechanically operated.
When an air switching valve or the like is provided in the door body, the thickness of the door itself increases. Therefore, there is a disadvantage that the opening / closing angle of the door is limited.
The object of the present invention is to provide a side opening device that eliminates the above-mentioned disadvantages.

  In order to achieve the above object, a side opening device of the present invention includes a door body that is attached to a vehicle body by a hinge and opens and closes a door opening of the vehicle body, a handle that opens and closes the door body, An inflatable seal rubber comprising: a latch interlocking with the handle; an inflatable seal rubber disposed at a peripheral edge portion of the door opening of the vehicle body and contacting the peripheral edge portion of the door body; and a circuit for supplying air to the inflatable seal rubber. The circuit for supplying air to the vehicle is controlled by an opening / closing signal of the door body and a vehicle point passing signal or a vehicle speed signal.

  According to the present invention, the seal structure of the side door is automatically formed, so that an erroneous operation or the like is prevented. Further, since it is not necessary to provide an operation switch for the air supply circuit in the handle, the thickness dimension of the door can be reduced. Therefore, there is an effect that restrictions on the opening / closing angle of the door and the size of the door are reduced.

FIG. 1 is a plan view of a main part of a leading vehicle on a Shinkansen that implements the present invention.
A leading vehicle generally indicated by reference numeral 1 has a driver's cab 20, a conductor compartment 30, and the like in the vehicle body 10, and a side opening device 100 is provided in an opening 40 that communicates with the conductor compartment 30.

  2 is a front view of the side opening device 100 as seen from the outside of the vehicle body, FIG. 3 is a front view of the side opening device 100 as seen from the inside of the vehicle body, FIG. 4 is a side view of the side opening device 100, and FIG. It is sectional drawing of a part.

The side opening device 100 has a door main body 110, and the door main body 110 is attached to the vehicle body 10 so as to be opened inward by two hinges 120.
A push-type handle 130 is provided on the vehicle outer side of the door main body 110, and the door main body 110 can be opened inward from the vehicle outer side by pushing the handle 130.
Inside the door main body 110, a rotary handle 140 operated by a crew member such as a conductor is equipped. A bolt operated by the handle 140 and two latches 150 interlocked via a link rod are provided. The door body 110 is locked and unlocked by engaging and disengaging the catch 160 on the vehicle body side.

As shown also in FIG. 5, the door main body 110 is provided with an opening 114 for a window, and the window frame 200 having the glass 210 is attached to the door main body 110 so as to be opened inward by two hinges 220. It is done.
The window frame 200 is locked and unlocked with respect to the door main body 110 by a revolving handle 230.

An inflatable seal rubber 300 is disposed on the peripheral edge 42 of the opening 40 to the conductor compartment. The inflatable seal rubber 300 has a function of expanding when air is supplied and contracting when air is extracted.
The inflatable seal rubber 300 is interposed between the door body 110 of the inner opening and the peripheral portion 112 of the door main body 110 and the inner side of the peripheral portion 42 of the opening 40 of the vehicle body when the vehicle body opening is closed from the inside. Is arranged.
Therefore, when air is sent to the inflatable seal rubber after the door body 110 is closed, the inflatable seal rubber 300 expands, sealing between the door body 110 and the opening of the vehicle body and maintaining an airtight state.

Similarly, an opening glass window is attached to the opening 114 provided in the door body 110. The opening glass window has a window frame 200 and a transparent glass plate 210 fitted into the window frame 200. The window frame 200 is attached to the door body 110 with a hinge 220 so as to be opened inward.
On the opposite side of the hinge 220 of the window frame 200, a pivoting handle 230 is provided, and the window frame 200 is locked and unlocked.

The expandable seal rubber 320 provided on the periphery of the opening 114 of the door body 110 abuts the window frame 200 at the position where the opening glass window is closed.
In this state, when air is supplied to the expandable seal rubber 320, the expandable seal rubber 320 expands and seals between the opening of the door body 110 and keeps airtight.

Next, the structure of the circuit which supplies the air to the inflatable seal rubber of the side opening device and the opening window of the present invention will be described. A control valve for opening and closing the air supply pipe and the air circuit to the expandable seal rubber is installed on the vehicle body side.
The side opening device and the opening window are required to be securely closed when the vehicle changes from a stopped state to a traveling state higher than a certain speed, and air is sent to the inflatable seal rubber to form a seal structure. .
Therefore, means for confirming that the door body of the side opening door is in the closed position, for example, a limit switch is provided.

When it is confirmed that the side door is closed and the vehicle has passed a predetermined point or the vehicle speed exceeds a certain level, the control valve is operated to send air to the inflatable seal rubber to form an airtight structure.
When the vehicle approaches the stop position, the control valve is operated by the point passing signal or the vehicle speed signal, and the air of the expandable seal rubber is removed.
As a result, the airtight structure is released, and the side door and the opening window can be manually opened on the vehicle interior side.
