Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle window protection plate attached to a train window frame for emergency treatment when a window glass breakage of a passenger car or the like occurs, and a method of attaching the same.

[0002]

2. Description of the Related Art Frequent accidents have occurred in which ice adhered to the bottom of a train falls as a lump and crushes crushed stones beneath a track, breaking a window glass of a passenger car. This is because, in winter, especially when the powder snow adheres to the bottom of the train as ice, when the train enters an area where the temperature is relatively high, the ice falls as a lump and jumps up the crushed stone below the track, Attracted by a train, or especially in a tunnel, which hits the walls of the tunnel and breaks the window glass of the coach.

In order to deal with such an accident, emergency measures using a vehicle window protective plate or the like are particularly important when the train speeds up, and when the train enters a tunnel and travels inside the tunnel, large internal and external trains are generated. Conventionally, it has been difficult to withstand the pressure difference. In that case, there has been no other method than the slow operation in the state where the window glass has been broken in the past, and the train has been greatly disordered. Then, they entered the dock to install the new window glass, and could not be re-run until the repair putty was cured.

[0004]

The present invention relates to a vehicle window protective plate used for emergency treatment when a window glass of a passenger car or the like is broken. First, such a vehicle window protective plate is used. As described above, it is necessary to withstand the pressure difference between the inside and outside of the train that occurs when the train enters the tunnel and runs in the tunnel, as described above.

Second, the vehicle window protection plate must be easily mountable from the inside of the train. Limited express trains often have double-glazed windows, so it is necessary to take care not only when all two windows are broken, but also when only one (usually the outside) is broken. Even if one is left, it is not possible to drive normally in consideration of safety. In this way, the mounting operation must be performed only from the inside of the train with one window glass remaining.

Third, window guards must not damage the train due to such first aid measures.
For example, it is not possible to take measures such as making a hole with a drill and attaching with a screw.

Therefore, the present invention withstands a pressure difference between the inside and outside of the train generated when the train rushes into and runs through the tunnel, and operates the train from the inside of the train in a short time without damaging the train. It is an object of the present invention to provide a vehicle window protection plate and a method of mounting the same.

FIG. 2 is a sectional view taken along the line GG of FIG. 1 and taken in the direction of the arrow, and shows a state in which it is attached to the window frame. The right side of the figure corresponds to the inside of the train, the left side of the figure corresponds to the outside of the train window, and the upper and lower sides of the figure correspond to the upper and lower sides of the actual window. FIG.
FIG. 5 is a cross-sectional view taken along the line HH, taken along the line −H and viewed in the direction of the arrow, and shows a state where the right half is folded upward with a hinge at the center by a dashed line.

In FIG. 2, reference numeral 1 denotes an outer glass of a train double window, and 2 denotes an inner glass thereof. 3 and 4
Is a window frame and its inner edge, and the same configuration is shown symmetrically at the top and bottom of the figure. The vehicle window protection plate of the present invention is mounted in the window frame.

1 to 3, 10 is a main panel, 11 is a flange portion thereof, 12 is a toggle clamp, 1
4 is a rod-like member, 15 is a pressing plate, 16 is a compression spring, 17 is a connection block, 18 is a side wall of a main panel, 20 is a hinge, 21 is a square pipe for reinforcement, 22 is a sheet, 23
Indicates a cushion.

As shown in FIG. 2, the main panel 10 has a window parallel surface having a size that penetrates the window frame 3 and almost covers the window frame 3, and extends in the direction from the window parallel surface toward the inside of the window. In the example, the side wall 18 that rises at a right angle and the flange portion 11 extending parallel to the window parallel surface in the vertical or horizontal direction from the side wall 18 are integrally formed of, for example, aluminum. The flange portion 11 extends at least vertically or horizontally to a greater extent than the window frame in order to support the inside of the window frame against an external suction force generated when the train goes out of the tunnel, for example. In the illustrated example, the side wall 1
Although the flanges 8 and the flanges 11 are provided on all sides of the main panel 10, they can be provided only on one of the upper, lower, left and right sides in consideration of the size of the window, material strength, and the like.

When the main panel has a large size, it can be folded by the hinge 20 or the like. FIG. 3 shows an open state of the folded structure by a solid line, partially omitted, and a dashed-dotted line showing a state where the right half is folded upward by a central hinge. Square pipe 21
Is for reinforcing the mechanical strength. A sheet (film) 22 for connecting the panels is provided to prevent a gap between the main panels by hinge installation. It is desirable that the sheet be thin enough to be loosened when folded. Also,
Such a folding structure is not necessary for a small window, and a single panel structure can be obtained.

The vehicle window protection plate of the present invention is firmly fixed to the window frame 3 of the train. For suction force outward from the window,
The aforementioned flange portion 11 is provided. Further, the vehicle window protection plate of the present invention restricts the vertical and horizontal movement by pressing the pressing member (the pressing plate 15) against the inside of the window frame from above and below or from right and left, and also from outside the window. The sliding movement of the window in the inward direction based on the pressing force acting inward is restricted. This sliding movement is performed by frictional force between the push plate 15 and the inner surface of the window frame, or when the inner edge portion 4 of the window frame is projected as shown in the drawing, the side surface of the push plate 15 is supported by the projected inner edge portion 4. Regulated by Hereinafter, the fixing by the push plate 15 will be described in detail.

In the illustrated example, a toggle clamp 12 is used as a pressing means for pressing a pressing plate 15 as a pressing member against the window frame 3. As can be seen in FIG. 1, the toggle clamp 12
Although four pairs are used in a pair and vertically symmetrically, the number of the toggle clamps 12 to be used may be sufficient as long as the number of the toggle clamps 12 used is sufficient to fix the vehicle window protection plate to the window frame 3. The pressing force of the toggle clamp, the configuration of the window frame, the material, and the like can be appropriately changed. In addition, up and down,
Although toggle clamps are shown on both the left and right sides, either one can be fixed sufficiently firmly.

FIG. 4 shows such a toggle clamp.
This will be described with reference to the principle configuration diagram shown in FIG. In the figure, 1
3 is an operation handle, 30 is a connection link, 31 is a linear moving member, 32 is a slide tube, 33 is a fulcrum of the operation handle, 35
Denotes a support, and 36 denotes locking means. And such a toggle clamp is attached to the main panel 10.

The upper part of FIG. 4 shows a state at the time of clamping,
In this case, the operation handle 13 rotatably supported about the fulcrum 33 is in a depressed state. The sliding tube 32 and the fulcrum 33 for linearly moving the linearly moving member 31 are supported by a support 35 fixed to the main panel 10.
Attached to. And this operation handle 13
Is held in such a manner that the lock means 36 for preventing return works and the pressing means is surely in a pressurized state. Especially,
Since the car window protection plate is used where vibration occurs,
It is necessary to reliably maintain a pressurized state against vibration. The lock means 36 for preventing return is illustrated in the drawing, and is held in a depressed state by the elastic force of a pair of left and right roller catches made of polyacetal resin or the like.

As described above, when the lock means 36 for preventing return is operated, the operating handle 13, the connecting link 30 pin-connected to the tip thereof, and the connecting link 3
The rectilinear moving member 31 pin-connected to the opposite end of 0 is substantially straight as shown in the drawing, whereby the rectilinear moving member 31 moves forward and presses the above-described push plate 15 against the inner surface of the window frame.

When the operating handle 13 is operated upward against the elastic force of the roller catch of the lock means 36, as shown in the lower view of FIG. Through this, the rectilinear moving member 31 is retracted. This corresponds to the release of the toggle clamp, and the above-described push plate 15 is separated from the inner surface of the window frame.

As described above, when the rectilinear moving member 31 is moved by the clamp operation of the toggle clamp 12, the movement is performed as shown in FIG.
The push plate 15 is pressed against the inner surface of the window frame 3 via the connection block 17 and the rod-shaped member 14. A rod-like member 14 for connecting the connection block 17 located inside the side wall 18 and the push plate 15 located outside the side wall.
Is provided through a hole formed in the side wall 18. The compression spring 16 is provided to absorb the dimensional error and variation in the size of the window frame and to reliably press the push plate 15 against the inner surface of the window frame 3. Each one of the toggle clamps 1
2 is sufficient. Also, an elastic body such as rubber can be used instead of the compression spring. The toggle clamp 12 as the pressing means is easy to operate and adjust, and is structurally simple.

Further, in order to press the inner surface of the window frame reliably and without deforming or damaging the inner surface of the window frame, the pressing member is provided with a plate, such as the illustrated pressing plate 15. It is desirable to have a shape.
And, as can be seen particularly in FIG.
Two push bars 15 are provided at both ends of the push plate 15 so that a uniform pressure is applied to the push plate 15, and the two rod members 14 are connected to both ends of the connection block 17. The propulsive force of the toggle clamp 12 is configured to be transmitted to the center of the connection block 17.

The push plate 15 is pressed against the inner surface of the window frame 3 and receives an inner edge protruding from the inner surface of the window frame 3 as shown in FIG. If a part is present, it can be supported by it. When such a protruding portion cannot be used on the inner surface of the window, an elastic member such as rubber is attached to the surface of the push plate 15 that contacts the window frame 3, and the frictional force causes
It can support inward loads.

Further, a viewing window for confirming whether the pressing member is properly set on the window frame is provided.
It can be provided on the side wall 18. Through this viewing window,
You can check if the panel is pushed in normally.

As described above, a large pressing force and a suction force are applied to the entire surface of the normally installed vehicle window protection plate as a dispersed load when entering and exiting a tunnel. The suction force is supported by the flange portion 11, and the pressing force is supported by the rod-shaped member 14 as a shearing force. The vehicle window protection plate of the present invention has a structure that can sufficiently withstand such a shocking pressing force and suction force.

When the vehicle window protective plate of the folded configuration is folded and stored or transported as shown by the dashed line in FIG. 3, the transport window protective plate is inserted into the holes drilled through the two flange portions 11 to be transported. The hook of the shoulder belt is hung. The hook also prevents opening during folding.

A configuration in which a cam is used as the pressing means instead of the above-described toggle clamp will be described with reference to a conceptual diagram shown in FIG. In the figure, reference numeral 40 denotes a cam operated by the operation handle 13, and 41 denotes a cam follower. The cam follower 41 is rotatably supported by the tip of the above-mentioned rectilinear moving member 31. The upper part of FIG. 5 shows the clamped state, and the lower part of FIG. 5 shows the released state.

At the time of clamping, the operating handle 13 rotatably supported about the eccentric fulcrum 33 is
In the illustrated example, the cam 40 is rotated by operating downward. The cam follower 41 moves in accordance with the cam shape, and the rectilinear moving member 31 connected to the cam follower 41 moves upward in the figure. The straight moving member 31 includes the connecting block 17 and the rod-shaped member 1 described above.
4, the push plate 15 is connected, so that
By rotating the operation handle 13 downward in the figure, the pressing plate 15 can be brought into pressure contact with the inner surface of the window frame (not shown).

At the time of release, in the illustrated example, when the operating handle 13 is turned in the horizontal direction, the cam follower 41 and the rectilinear moving member 31 retreat downward in the figure due to the cam shape, and this is the connecting block 17 and the rod-like member 14. The pressing contact between the push plate 15 and the inner surface of the window frame can be released through the contact.

Although the structure using such a cam is slightly complicated in structure, it can be reliably fixed particularly against a pressing force from outside the window, similarly to the above-mentioned toggle clamp. .

FIG. 6 is a conceptual diagram of still another example in which a link structure is used as the pressing means. In this example, a pair of upper and lower or left and right push plates 15 are simultaneously pressed against or separated from the inside of the window frame, but the figure shows a separated state.

When the link A42, link B43, and link C44, which are pin-connected to each other, are operated by appropriate operation means such as the operation knob 45 so as to be aligned in the vertical direction in the illustrated example. , Link B43
And a pair of push plates 1 via a connecting block 17 and a rod-shaped member 14 which are respectively pin-connected to the link C44.
5 are simultaneously pressed against the inner surface of the window frame.

In order to separate the pair of push plates 15 from the inner surface of the window frame, the operation knob 45 is rotated counterclockwise, and the link A
42 is directed sideways to the state shown in the figure, the push plate 1
The compression between 5 and the inner surface of the window frame is released.

By using such a link structure as pressing means, it is possible to lock up and down or left and right simultaneously.

[0040]

According to the present invention, the flange portion of the main panel is brought into contact with the inside of the window frame and the pressing member is attached to the main panel so that the pressing member is moved up and down or left and right with respect to the inside of the window frame. Since the vehicle window protection plate is configured to support the pressing force and suction force acting on the inside and outside of the window as well as the pressing, up, down, left and right directions, the train is running when entering the tunnel and running inside the tunnel In addition to withstanding a large pressure difference between the inside and outside, there is an effect that the mounting operation can be reliably performed from the inside of the train in a short time without damaging the train.
