The present invention relates to the airtight structure of a window, and more particularly to the airtight structure of an open window installed in the cab of a high speed rail vehicle.

The structure for airtightness of the cab opening window 101 of a high speed train, such as the Gyeongbu high speed train KTX and the Korean high speed train G7, which is operating in Korea, is very simple, as shown in FIGS. 4 and 5.

That is, the sealing materials 103, 104, 105, and 106 formed at the edges along the shape of the window frame 102 of the window 101 are configured so that two of the cross-sections in the shape of a substantially rectangular shape abut each other. The sealing materials 103 and 105 are fixed to the window frame 107 attached to the wall, and the other sealing materials 104 and 106 are attached to the window 101 to be opened and closed to overlap when the window 101 is in the closed state. Shut off noise or air from the system.

In addition, a handle 108 is attached to one side edge of the window frame 102 to open and close, and when the opening and closing operation is performed by pulling or pushing the handle 108, one or more hinges 109 near the other edge This becomes the rotation center of the opening and closing operation.

On the other hand, the sealing member 105, 106 is very close to the distance from the center of rotation so that the sealing member 105, 106 is pushed or pressed repeatedly by the opening and closing operation of the window 101, it is easily torn or partially There was a problem of breaking such as rupture.

In addition, since the sealing members 103, 104, 105, 106 are structurally overlapped, the resilient restoring force of the rubber sealing member decreases due to repeated opening and closing operations, the time-dependent action and deformation caused by exposure to sunlight. Due to this, there was a problem that the original shape is broken and the sealing function is lost.

The present invention has been made to solve the above-mentioned problems of the prior art, by reducing the tinnitus phenomenon and noise caused by the pressure difference generated during high-speed driving and tunnel passing for the high-speed railway vehicle cab opening window to create a quiet cab environment It is an object to provide an airtight structure of a window that can be created.

In order to solve the above problems, the present invention, in the airtight structure of the open window installed on the side wall in the cab of the high-speed vehicle, the window frame of the window fitted to fit the shape of the window frame fixed to the wall to support the window and And recesses are formed at both sides of the window frame cross section, glass is inserted into the gap member at the outer recess, and the gap is formed at the inner recess to seal a gap formed between the window frame. Accordingly, the sealing member is characterized in that the double hermetic structure is fixed in position inward with the ribs in between.

In addition, the sealing member of the present invention is characterized in that the hollow elastic material having an elasticity.

In addition, the sealing member of the present invention is characterized in that the projection is formed to extend in one direction so as to closely contact the wall surface of the gap formed between the window frame and the window frame.

In addition, the cross section of the window frame is characterized in that the "I" shape.

Hereinafter, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

However, the following examples are merely exemplary, various modifications are possible within the technical spirit of the present invention, and the present invention is not limited.

1 is a cross-sectional view showing an airtight structure of a window of the present invention, FIG. 2A is an enlarged view of the sealing material in FIG. 1, FIG. 2B is an enlarged view of a hinge and a sealing material portion, and FIG. 3 is FIG. Fig. 11 shows the operating state of.

The airtight structure 1 of the window of this invention is an open window 10 installed in the side wall in the cab of a high speed vehicle, and fixed to a wall for supporting the window 10, as shown to FIG. It consists of a window frame (2).

The window 10 is formed of a rectangle or an ellipse and is supported by a window frame 2 installed on a wall (side wall) in a cab of a high speed vehicle, and is fitted to fit the shape of the window frame 2. (11) and a handle (12) is attached to one end of the window frame (11) so as to be openable and close, and a hinge (13) which is a rotational center on the other end of the window frame (11) and the window frame (2). It is attached across. Therefore, when the handle 12 is rotated and pulled forward, the handle 12 side is pulled into the cab inside the cab by the center of rotation of the core 14 of the hinge 13 attached to the other side, so that the window frame 2 and the space are formed. Opening takes place. In addition, one or more said hinges 13 are attached as needed.

As for the said window frame 11, the cross section cut | disconnected in the width direction becomes substantially "I" shape, As shown in FIG. 2, recessed parts 15 and 16 are formed in both left and right sides, and the left side ( The glass 17 is inserted into the gap member 18 in the recessed part 15 inside, and the two sealing materials 19 and 20 are interposed between the ribs 21 in the right side (outer side) recessed part 16. It is a double hermetic structure which is placed and fixed side by side.

The sealing material (19, 20) is made of a rope-shaped elastic material having an elasticity, a hollow type having one or more cavities 22 formed therein, between the window frame (2) and the window frame (11) The protrusions 24 extending in one direction are formed so as to be in close contact with the wall surface of the gap 23 formed in the groove. The first sealing material 19 located on the outside is larger in size than the second sealing material 20 located on the inner side along the gap 23, and primarily blocks the outside and the cab. Two projections 24 are formed at predetermined intervals so as to be in close contact with both wall surfaces forming the 23). Further, a rib 21 is formed at one side, and a second sealing material 19 is attached to the outside of the first sealing material 19 to be smaller than the first sealing material 19 and is substantially perpendicular to the outside of the rib 21. The second sealing member 20 is provided with a protrusion 24 on only one side thereof.

On the other hand, the sealing materials (19, 20) may be different in size as necessary, it is obvious that also in the shape of the cross-section can be modified into hollow or solid and other forms.

The operation of the airtight structure 1 of the window according to the present invention having the above-described configuration will be described below.

The airtight structure 1 of the window of the present invention is a double structure in which the first sealing material 19 and the second sealing material 20 are positioned side by side with the ribs 21 interposed in the recesses 16 of the window frame 11. Since it is an airtight structure, by sealing the clearance 23 between the window frame 11 and the window frame 2 through 2 times, it can block the noise which generate | occur | produces in the outside air and at the time of high speed running, and is quiet in a cab environment. Can be formulated.

Further, the distance between the core 14 serving as the center of rotation of the window 10 and the first and second sealing materials 19 and 20 is sufficiently far from the conventional one shown in Fig. 2, and the first and second sealing materials ( 19 and 20 are attached to the concave portion 16 in the form listed, so that the first and second sealing materials 19 and 20 are not deformed by being pushed or excessively pressed during opening and closing, 2 The cavity 22 is formed inside the sealing materials 19 and 20, and since the elastic restoring force is very excellent, there is no fear of damage even if it is used for a long time.

Moreover, since the protrusion 24 is formed in the 1st, 2nd sealing material 19 and 20, and closely adheres to the wall surface of the clearance 23, the sealing effect can be improved further.

The present invention can create a quiet cab environment by reducing the tinnitus phenomenon and noise caused by the pressure difference generated during the high-speed driving and tunnel passing for the vehicle cab opening window of the high speed railway.
