Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle window protective plate which is attached to a window frame in place of a window glass as an emergency measure when a window glass of a passenger car or the like is broken.

[0002]

2. Description of the Related Art Accidents have often occurred in which ice adhered to the bottom of a train falls as a lump and bounces up crushed stones under the track, breaking the window glass of a passenger car. This is because in the winter, especially when powdered 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 in chunks and bounces up the crushed stones under the track. Attracted by the train, or especially in the tunnel, it hits the walls of the tunnel and breaks the window glass of the passenger car.

In order to deal with such an accident with a car window protection plate or the like, it is necessary to take emergency measures, especially when the train runs into a tunnel and when the train runs inside the tunnel. It has been conventionally considered difficult to withstand the pressure difference. In that case, conventionally, there was no other way than the slow running of the train in the state where the window glass was broken, and the train schedule was greatly disturbed. Then, it was in a situation where it could not be restarted until the repair putty was cured after it was docked to install a new window glass.

[0004]

There are two types of window glass for passenger cars, such as double-pane window glass such as passenger compartment window glass, and single glass for passenger entrance doors and crew window. The present invention is
It is intended to provide a vehicle window protective plate used as an emergency measure when a single windowpane is broken or when two double panes are broken. An easily conceivable method is to apply the panels from the inside and the outside and tighten them with screws, etc., but at least two workers are required inside and outside the window, and the screws are loose due to vibration during train running. There is a danger of coming out.

Therefore, firstly, it is necessary for one person to easily and surely mount the car window protective plate from the inside of the train. Secondly, such a car window protective plate needs to withstand a large pressure difference between the inside and outside of the train, which occurs when the train runs into the tunnel and during running in the tunnel.

Thirdly, the car window guards must not damage the train due to such first aid measures.
For example, it is not possible to adopt a means such as drilling a hole and attaching it with a screw.

[0007] Therefore, the present invention is capable of withstanding the shock pressure when a train enters a tunnel and goes out of the tunnel, and at the same time, one person can easily and reliably injure the train from the inside of the train. It is an object of the present invention to provide a vehicle window protective plate that can be mounted and operated without any operation.

1 to 3 are views showing an example of a car window protective plate to which the present invention is applied, and FIG. 1 is a diagram showing the car window protective plate attached to a window frame for a passenger entrance door of a train. In this state, the left side of the train shows the overall configuration as seen from the inside (rear side) of the train, and the right side of the view shows the vertical cross section of the sub-section. FIG. 2 is a transverse cross-sectional view of the vehicle window protective plate of FIG. 1 cut in the lateral direction. FIG. 3 is a transverse cross-sectional view taken along the horizontal direction as in FIG. 2, but is a partially enlarged view taken along the hinge joint portion.

In these figures, 1 is a window frame, 2 is an outer panel, 3 is an inner panel, 4 is a belt, 5 and 6 are grips, 7 is an inner panel opening, 8 is a connecting member, 10 is a hinge, and 11 is a hinge. Spacing tube, 12 oblong holes, 13 and 14 screws or rivets,
Reference numeral 15 is a buckle for locking the belt, and 16 and 17 are guides for the belt.

The present invention will be described below with reference to an exemplary vehicle window protective plate in which the vertical and horizontal directions are specified, but the present invention can also be applied to a vehicle window protective plate in which the upper and lower sides and the left and right sides are interchanged. .

The car window protective plate of the present invention is one that can be installed by one person from the inside of the train after removing broken pieces of the window glass, and the inner panel 3 provided inside the window so as to sandwich the window, Outer panel 2 provided outside the window
It consists of Both panels have substantially the same dimensions as the window opening so as to close the window opening. Then, the inner panel 3 supports the suction force toward the outside,
Either the length or width must have a size larger than the window opening size. In the illustrated example, the vertical and horizontal dimensions are made larger than the window opening size. On the other hand, the outer panel 2 is configured such that one dimension (horizontal dimension in the illustrated example) in the vertical and horizontal directions is larger than the corresponding dimension (horizontal dimension) of the window opening in order to support the compressive force from the outside to the inside. The other dimension (vertical dimension in the illustrated example) is configured to be smaller than the corresponding dimension (vertical dimension) of the window opening in order to move the window from the inside to the outside during mounting. The size relationship of these dimensions can be seen in the vertical dimension, in particular, in the vertical sectional view on the right side of FIG. 1, and in the lateral dimension, in the horizontal sectional view of FIG.

After the inner panel 3 and the outer panel 2 are attached to the window, they are fixed together by using a coupling lock means (belt 4 with a lock fitting) as will be described later in detail. In order to improve the property, the inner panel 3 and the outer panel 2 are, as shown in the diagram on the right side of FIG. 1, in the illustrated example, by the hinges 10 provided at the upper and lower two places on the left end,
With that point as a fulcrum, the right ends of both panels are openably and integrally connected.

The connection by the hinge 10 will be described in detail with reference to FIG. 3, which is a sectional view taken through the hinge 10 in a lateral direction. The members A and B represent two openable and closable members that form the hinge 10. One member B is fixed to the inner panel 3 with screws 14 (or rivets). The other member A has a screw 1 attached to the connecting member 8.
It is fixed by 3 (or rivets). This connecting member 8 is fixed to the outer panel 2 by appropriate means,
It is bent inward at a right angle from the outer panel surface. As a result, the inner panel 3 and the outer panel 2 can open and close the other end side between the two panels with the hinge 10 as a fulcrum (that is, both panels can be parallel to each other).

Further, in order to facilitate the attachment to the window, the member A of the hinge 10 and the fixing of the connecting member 8 with the screw 13 or the rivet are arranged so that the space between the inner and outer panels in the hinge mounting portion can be adjusted. Tube 11 and slot 12
Done through. Since the length of the spacing tube 11 is configured to be slightly longer than the thickness of the connecting member 8, the connecting member 8 is fixed to the member A, that is, to the inner panel 3 even when they are integrally tightened with the screw 13. Thus, it is possible to move within the length of the long hole 12.

In order to attach the vehicle window protective plate thus constructed to the window frame 1, the inner panel 3 as shown in FIG.
The grip 6 attached to the outer panel 2 is gripped with one hand while the grip 5 attached to the outer panel 2 is gripped with the other hand through the inner panel opening 7. In the illustrated example, the hinge 10 located on the left end side of the inner and outer panels is used as a fulcrum, and the right end side of the inner and outer panels is opened. Move it to the outside.

Next, the inner and outer panels are closed, that is, parallel to each other, with the space between the left and right ends of the inner and outer panels being maximized by the space adjusting mechanism composed of the space tube 11 and the elongated hole 12. At this time, the inner and outer panels are so sized that the reinforcing member 18 fixed to the outer panel 2 contacts the right window frame 1.
It is on the right side of FIG. The reinforcing member 18 reinforces the strength of the panel and also functions as a guide for lateral positioning. In this way, by closing the inner and outer panels, the space on the left end side of the inner and outer panels is opened, and the space is also maximized by the above-mentioned space adjusting mechanism. In the example, it is possible to shift the inner and outer panels to the left.

Therefore, by shifting the inner and outer panels to the left,
After being set at a predetermined mounting position, the outer panel and the inner panel are integrally coupled to each other with the window frame sandwiched therebetween. In the illustrated example, the belt 4 is used as an integral connecting means, and is integrally fastened. As a result, the inner and outer panels are fixed to each other and also to the window frame 1.
At this time, in the above-mentioned space adjusting mechanism, the inner and outer panels are
It is possible to narrow the gap so that it sandwiches. A friction material such as rubber is attached to a portion of the inner and outer panels that abuts on the window frame 1 so that the inner and outer panels are not displaced on the window frame 1 and the train window frame is not damaged.

The tightening of the panel with the belt 4 is shown in FIG.
As can be seen in the right-hand drawing of Fig. 3, the upper and lower parts and the central part are provided, but the number of tightening points can be any number sufficient to fix both panels and the window frame. This belt 4 has guides 16 and 17 as shown in FIG.
And can be locked using any suitable locking means such as the buckle 15 shown. The lock can be released with the buckle metal fittings. By using such a belt with a lock fitting as the tightening means, the structure can be simplified and the tightening can be surely performed, and the inner and outer panels can be easily attached to the window frame 1. As described above, this means that when the inner and outer panels are mounted, the outer panel 2 is opened, passed through the window frame 1, and then closed, the inner and outer panels must move to the right side in FIG. At this time, the reinforcing member 18 moves to such an extent that it comes into contact with the window frame 1. However, if the belt 4 is used, this can be achieved by easily deforming it as shown by the alternate long and short dash line on the right side of FIG. Become. Then, when the belt is tightened, the tight belt comes into contact with the window frame 1 on the right side, and functions as a positioning means in the left-right direction of the inner and outer panels.

[0023]

According to the present invention, the outer panel and the inner panel of the vehicle window protective plate are rotatably supported with respect to each other so that the other end can be opened and closed with one end as a fulcrum.
By configuring so that the mutual distance can be adjusted at the one end side, it can withstand a large pressure difference between the inside and outside of the train that occurs when the train rushes into the tunnel and while traveling inside the tunnel, and even from the inside of the train, even one person can There is an effect that the train can be easily and reliably installed without damaging the train.
