Abstract

PURPOSE:To enhance safety through a light interceptor between the motorman's compartment and passengers' room of a train or the like, by disposing plural light interception plates on the window between the motorman's compartment and the passengers' room to extend almost perpendicularly to the surfaces of the window to intercept rays of light below a predetermined angle of incidence. CONSTITUTION:Plural strip-shaped light interception plates 18 whose length is almost equal to or slightly larger than the height of the partition window 15 between a motorman's compartment 12 are passengers' room 13 are disposed on the window in the motorman's compartment so that the plates vertically extend at prescribed intervals perpendicularly to the surface of the window. The width lof the light interception plates 18 and the intervals (d) between them are so set that the angle theta between the window and the straight line extending on the front edge (a) of the interception plate and the rear edge (b) of the next one is larger than the angle of reflection of rays of light which would pass through the window, reflect on a front window 14 and converge on the eye 16a of the motorman. The rays of light are thus prevented from entering into the eye of the motorman. As a result, safety is enhanced.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a light shielding device that prevents light entering the driver's cab from the passenger cabin from being reflected by the window glass in front of the driver and interfering with driving. Regarding.

[Prior art]

Generally, in a vehicle that transports passengers such as a train or bus, when the driver's cabin and passenger cabin are installed next to each other, at night or in a tunnel, the illumination light from the cabin enters through the window glass at the boundary with the driver's cabin. This light may reflect off the window glass in front of the driver, making it difficult to see in front of the driver and hindering driving. For this reason, in the past, as shown in Figure 1, a curtain (4) was placed over the window (3) of the partition between the driver's cab (1) and the passenger compartment (2) at the rear.
In addition, opening and closing the curtains each time entering and exiting a tunnel is a hassle for the driver, and can disrupt his or her attentiveness while driving. This is not a desirable thing.

In addition, as shown in Figure 12, if curtains (4) are provided on the back and sides of the driver and the remaining windows between the cabin (2) and the driver's cabin (1) are opened, Although the service is satisfied, the driver's field of view to the right in the figure is obstructed, resulting in a major hindrance to driving, which is not favorable for safe driving.

[Purpose of the invention]

The present invention has been made in view of the above circumstances, and is a simple and rational means. Specifically, the present invention is a method that obstructs the field of view necessary for driving during the path of the light flux that enters the driver's cab obliquely from the cabin and is reflected. The aim is to solve the problems of the conventional technology by providing a light-shielding plate that does not interfere with the driver, eliminate driving problems caused by reflected light, and provide a vehicle that can safely drive with less fatigue and less stress on the driver. be.

[Structure of the Invention] The structure of the invention is such that the light from the rear is directed vertically in the east path of the front window, in the space between the cabin and the driver's cab, and
This is a light shielding device in which multiple light shielding plates, whose surfaces are almost perpendicular to the window surface, are arranged to block light that enters at a predetermined angle or less, and light from the rear is reflected on the front window glass. This is a light shielding device in which a light shielding plate larger than the cross section of the light flux is installed in the driver's cabin so that the field of view necessary for driving is not obstructed in the light flux path leading to the driver's eyes and the vicinity of the eyes, and it also blocks light from the rear. is reflected on the front window glass and reaches the driver's eyes and the area around them.
, a plurality of light shielding plates are arranged in the vertical direction and the plate surfaces are almost perpendicular to the window surface so as to block light incident at a predetermined angle or less,
Furthermore, in the light shielding device, a light shielding plate larger than the cross section of the remaining light flux is disposed in the driver's cab so as not to obstruct the field of view necessary for driving in the light flux path.

[Function and Examples]

The details of the embodiment of the present invention will be explained with reference to Figures 3 to 2. First of all, to explain the invention of spear 1 with respect to the figures 3 to 3, a
υ is a vehicle such as a train or bus, α2 is a driver's cabin, (131
is the passenger compartment, α→ is the front window of the driver's cabin, α is the window of the partition between the passenger compartment 03) and the driver's cabin a, (161 is the driver's seat, (17)
1 is the driver's cabin (/jα) at the window (/jα) behind the driver's seat (E6).
It is a curtain that is darkened in the middle of the day. In the present invention, in such a configuration, the illumination light inside the cabin enters the driver's cab a through the window α9 without a curtain, is reflected at the window αa in the front of the driver's cab, and enters the driver's field of view. Therefore, on the driver's cab side window surface of the window α of the partition, a plurality of strip-shaped light shielding plates αa, which are approximately the same height as the window a51 or slightly longer than this height, are placed along the longitudinal direction at predetermined intervals. At the same time, the light shielding plate is arranged so that the plate surface of the light shielding plate is substantially perpendicular to the window surface.

The relationship between the width of this light shielding plate 0 barrel (1) and the distance between the light shielding plates (d) is a spear! As shown in the figure, 17(1) may be varied and the interval (tL) may be constant, or as shown in Fig. 24, the interval (f) may be varied and r+](/') may be constant. Furthermore, the width (1) and spacing (d) may be arbitrarily selected.The point is that the front edge of the light-shielding plate that matches the shape is α).
The angle θ formed by the tangent between Since it is only necessary to make it larger, the light shielding plate (181 width (1), distance 1
The setting conditions for tI% (d) are not specified. In this way, if the angle 0 formed by the tangent line connecting (b) and (h) is made larger than the angle of reflection of light, the interior lighting of the guest room will be completely blocked. The group is such that not only does it not obstruct the driver's field of view, but it also does not obstruct the view out of the front window from the passenger compartment.

Next, to explain Ikko's invention with respect to figures 7 to io, in the figure, for example, on the diagonal right side of the driver's seat (lfi),
A rectangular light-shielding plate a1 shorter than the height of the partition part gae is vertically arranged.

As shown in Figure 9, the N+ arrangement of the light shielding plate a9 is such that the light from the partition window (19) is
) and prevent it from entering the driver's eyes.
The width of the light shielding plate ←1 (height h) is set to be larger than the width and height of the light flux path that enters from window 09 and reaches the driver's eyes and the vicinity of the eyes, and the installation angle α is set to In other words, the direction of the driver's line of sight is made to match the direction of the driver's line of sight by using a shading plate (1!l) that is larger than the cross section of the light beam that enters from the window aω, is reflected by the window glass (+4), and reaches the driver's eyes (/6). It may be installed in a direction that does not block the area.

Also fang 10. As shown in Figure 1, a plurality of light shielding plates (11
may be provided separately under the same conditions as above.

In this way, by providing a light shielding plate larger than the cross section of the light flux in the light flux path, the illumination light from inside the cabin is completely blocked, and the light shielding plate does not obstruct the driver's field of view. The view outside the window is not obstructed too much.

In addition, IF/, Figure 2 shows the invention of Yaku 3,
This invention combines the inventions of Fang I and Fang Ko described above. In this case, a light shielding plate (1
The number of light shielding plates can be reduced, and the width of the light shielding plate provided in the driver's cab (121) can be made narrower.The light shielding effect is the same as that of each of the above inventions.

〔Effect of the invention〕

As described above, according to the present invention, the illumination light in the cabin does not reach the window glass in front of the driver's seat, and the driver's lateral field of view is not obstructed, making it possible to drive safely without interfering with driving. be. It also has excellent features such as being able to see the front from the cabin when driving in tunnels or at night, improving service to passengers.
