In a railroad car with chaise lounges arranged along the side structure, when passengers seated in the seats tried to see the display device installed in the opposite camouflage part, the normal direction of the display screen was the horizontal direction inside the car. Then it is hard to see. On the other hand, there is a problem that it cannot be seen when the normal direction of the display screen is vertically downward.

In addition, when a large number of large display devices are to be mounted on a vehicle, it is necessary to be able to quickly replace them in the event of a failure or the like. For example, if a display device of 20 inches or more is fixed to the vehicle structure, it is not easy to remove it by one person. This is because the fixing point is higher than the human head, so it is necessary to screw it while holding it.

On the other hand, if the display device is attached to the camouflage panel side, it is sufficient to connect the display device and the camouflage panel and then attach the entire camouflage panel to the vehicle structure, so that the display device can be easily attached to the vehicle structure. However, since the camouflage panel supports the display device, the rigidity of the camouflage panel side is required. Further, if the mounting base for mounting the display device on the camouflage panel is attached by welding or the like after the camouflage panel is formed, the camouflage panel itself is distorted and welding marks are visible when viewed from the front side, which makes the design unsatisfactory.

The present invention has been conceived in view of the above problems. More specifically, the camouflage panel according to the present invention is
The main body panel part having a flat part and
A groove rail provided integrally with the main body panel portion along the longitudinal direction on the back surface of the main body panel portion,
Have a panel opening provided in the flat portion,
At the upper end of the main body panel
The hook portion from the surface of the main body panel portion to the back side and the hook portion
An upper end hook having a protrusion provided at the tip of the hook portion,
It is characterized in that a claw rib formed in the downward direction of the hook pocket formed between the back surface of the main body panel portion and the upper end hook is formed.

Further, the railway vehicle structure according to the present invention is
The above-mentioned display device is mounted on the camouflage portion between the side structure and the ceiling of the railroad vehicle structure at an angle of 30 ° to 60 ° with respect to the side structure, and the display device is mounted on the panel opening for the display device. It is characterized by having a camouflage panel.

Since the camouflage panel according to the present invention integrally forms a groove rail in the width direction, it can be used as a bracket for fixing a device to be fixed to the camouflage panel, and further has an effect of improving the rigidity of the camouflage panel itself.

Further, since the groove rail is not connected to the camouflage panel by welding, the existence of the groove rail cannot be visually recognized even when viewed from the front side, and the groove rail can be directly used as a decorative plate.

Further, the camouflage panel according to the present invention can further improve the overall rigidity by fixing a 24-inch display device to the panel opening.

Further, since the display device is fixed not to the vehicle body side but to the camouflage panel itself, the display device can be replaced easily and quickly.

The drawings and the description of the camouflage panel according to the present invention and the railroad vehicle structure on which the panel is mounted are shown below. The following description exemplifies one embodiment and one embodiment of the present invention, and the present invention is not limited to the following description. The following description can be modified without departing from the spirit of the present invention.

FIG. 1 is a preview view of a vehicle having a camouflage panel 1 according to the present invention. It is a figure which looked at the other wife structure 85 from one wife structure. The inside of the vehicle has a ceiling portion 80, a floor surface 82, a wife structure 85, and a side structure 84. A door portion 84a and a window portion 84b are formed on the side structure 84. The seat 84c is arranged so as to face the left and right side structures 84, respectively.

The area between the window portion 84b and the ceiling portion 80 is referred to as a camouflage portion 88. A loading platform may be formed here. From the ceiling portion 80, a grip bar may be arranged for passengers who do not sit in the seat 84c to maintain their posture. Further, a stanchion pole may be arranged in the vehicle (the grip bar and the stanchion pole are not shown). The camouflage panel 1 according to the present invention is provided on the camouflage portion 88 between the window portion 84b (and the door portion 84a) and the ceiling portion 80.

The camouflage panel 1 has a panel opening 14 (see FIG. 2) that exposes the screen of the display device (display device 50). A plurality of the display devices 50 are arranged along the side structure 84. Therefore, in one vehicle, a considerable number of display devices 50 are arranged. In FIG. 1, one camouflage panel 1 of the left and right camouflage portions 88 is shown by diagonal lines. The portion of the display device 50 is not shaded.

FIG. 2 shows a perspective view of the camouflage panel 1 alone. FIG. 2A is a view seen from the front, and FIG. 2B is a view seen from the back. FIG. 2B shows the display device 50, the holding plate 26, and the reinforcing plate 32 among the parts mounted on the camouflage panel 1. Here, the "table" refers to the side seen by the customer from inside the vehicle. Further, in the camouflage panel 1, the "horizontal direction" means the vehicle traveling direction when attached to the camouflage portion 88, and the "vertical direction" means a direction perpendicular to the "horizontal direction". Further, the "upper" of the camouflage panel 1 refers to the side closer to the ceiling portion 80 when attached to the camouflage portion 88.

With reference to FIGS. 2A and 2B, the camouflage panel 1 is composed of a main body panel portion 10 having a flat surface portion and a lower plate portion 12 continuous with the main body panel portion 10 at a predetermined angle. ing. The angle formed by the main body panel portion 10 and the lower plate portion 12 is θ. The axis that vertically passes through the horizontal center of the main body panel portion 10 is referred to as a vertical axis, and the axis that horizontally passes through the vertical center of the main body panel portion 10 is referred to as a horizontal axis.

A panel opening 14 is formed in the main body panel portion 10. The panel opening 14 may be large enough to include the screen of a flat display (display device) of at least 20 inches, preferably 24 inches. Here, 24 inches means that the diagonal line 14a of the panel opening 14 is 24 inches.

Set screws 16 are arranged at both ends of the lower plate portion 12. The set screw 16 communicates with the locking tongue piece 18 on the back surface side. Therefore, when the set screw 16 is rotated, the locking tongue piece 18 on the back side of the lower plate portion 12 also rotates.

A plurality of groove rails 20 are formed in the lateral direction on the back surface of the main body panel portion 10. The groove rail 20 may also be provided on the back surface of the lower plate portion 12. Further, an upper end hook 22 is formed at the upper end of the main body panel portion 10. The display device 50 is attached so as to align the display surface 50D with the panel opening 14 from the back surface side of the main body panel portion 10. The main body panel portion 10 may be provided with not only the panel opening 14 for the display device 50 but also other through holes.

FIG. 3A shows a cross section taken along the line AA of FIG. 2B. This is a cross section of the groove rail 20. The groove rail 20 is integrally formed with the main body panel portion 10, and is formed by an opposing vertical wall 20a and an eaves portion 20b extending from the tip of the vertical wall 20a toward the facing vertical wall 20a. Has been done.

Here, "integrally" means that there is no boundary surface between the main body panel portion 10 or the lower plate portion 12 and the groove rail 20 when viewed in cross section as shown in FIG. 3A. That is, the main body panel portion 10 or the lower plate portion 12 and the groove rail 20 are simultaneously formed of the same material. Further, the main body panel portion 10 and the lower plate portion 12 are also integrally formed. More specifically, the camouflage panel 1 is formed by an aluminum extrusion method. Therefore, it may be said that the groove rail 20 is formed as an integral body having no boundary surface with the main body panel portion 10 or the lower plate portion 12. Similarly, it can be said that the main body panel portion 10 and the lower plate portion 12 are also formed as an integral body having no boundary surface.

By integrally forming the groove rail 20 with the main body panel portion 10 and the lower plate portion 12, the groove rail 20 functions as a reinforcing material for the camouflage panel 1. Since it is formed as an integral body having no boundary surface, the front side of the main body panel portion 10 and the lower plate portion 12 is not distorted, and the groove rail 20 is formed from the front side. I can't see it at all. Further, since such a reinforcing structure is formed as an integral part of the camouflage panel 1, it also contributes to weight reduction of the whole.

Therefore, after the formation of the camouflage panel 1, processing such as putty finishing for correcting the flatness of the front side becomes unnecessary. Therefore, powder coating becomes possible, and a beautiful decorative surface can be formed only by coating.

The rail opening 20u of the groove rail 20 is formed by the facing eaves 20b. The width of the rail opening 20u is the rail opening width 20u. A space wider than the rail opening 20u is formed on the main body panel portion 10 side of the eaves portion 20b. This portion is called the groove rail inner side 20i.

That is, in the groove rail inner portion 20i, the inner wall spacing 20aw of the vertical wall 20a is wider than the rail opening width 20uw.

FIG. 3B shows a typical example of how to use the groove rail 20. The fixing screw 30 composed of the head 30a and the lower neck 30b is used by inserting it into the groove rail 20. Specifically, the head 30a of the fixing screw 30 is inserted into the groove rail inside 20i so that the lower neck 30b protrudes from the rail opening 20u in the groove rail inside 20i.

The fixing screw 30 can move the groove rail 20 laterally and can be used at a predetermined position.

FIG. 4 shows a cross section of the upper end hook 22. This corresponds to the BB cross section of FIG. 2 (a). The upper end hook 22 is composed of a hook portion 22a facing from the front surface to the back side of the main body panel portion 10 and a convex barb 22b provided at the tip of the hook portion 22a. Therefore, a hook pocket 22c is formed between the back surface and the upper end hook 22.

Further, a claw rib 24 is formed in the lateral direction of the main body panel portion 10 slightly downward of the hook pocket 22c. As will be described later, this is for reinforcing the hooking with the camouflage panel receiver 88c (see FIGS. 6 and 7) on the vehicle body side. A groove rail 20 is formed adjacent to the upper end hook 22.

Next, a method of attaching the camouflage panel 1 according to the present invention to the vehicle body will be described. First, a display device 50 is attached to the camouflage panel 1. More specifically, with reference to FIG. 5, the fixing screw 30 is passed through the groove rail 20 arranged on the back surface of the main body panel portion 10, and the back side of the display device 50 is fixed to the main body panel portion 10 with the holding plate 26. do. The display surface 50D of the display device 50 is exposed from the panel opening 14 of the main body panel portion 10 toward the surface side of the main body panel portion 10.

Further, reinforcing plates 32 are attached to both ends of the camouflage panel 1 in the lateral direction. The reinforcing plate 32 may be called a reinforcing material. That is, a reinforcing material other than the reinforcing plate 32 may be attached. A fixing screw 30 passed through the groove rail 20 is also used for this mounting. The groove rail 20 is integrally formed with the main body panel portion 10, and is formed in the lateral direction of the main body panel portion 10. Therefore, there is an effect of suppressing bending in which the vertical axis of the main body panel portion 10 is displaced in the front-back direction.

On the other hand, since the reinforcing plate 32 fixes both ends of the main body panel portion 10 in the vertical direction, it is possible to suppress bending in which the horizontal axis of the main body panel portion 10 is displaced in the front-back direction. As a result, the rigidity of the camouflage panel 1 becomes high, and it does not bend even when attached to the camouflage portion 88.

When the screen of the display device 50 is wide, the panel opening 14 provided in the camouflage panel 1 also has a wide opening. When the display device 50 is fixed to the vehicle body side, only the panel provided with the wide opening must be fixed to the vehicle body. Then, even if the reinforcement integrated with the main body panel portion 10 is provided on the back surface side, the main body panel portion 10 is bent. This deflection is different for each camouflage panel 1. As a result, when they are installed in parallel, the appearance of the camouflage portion 88 is distorted as a whole.

Further, when the display device 50 is fixed to the vehicle body side, a gap may be formed between the panel opening 14 of the camouflage panel 1 and the screen of the display device 50. Further, when the panel opening 14 and the display device 50 are brought into close contact with each other, the surface of the camouflage panel 1 is distorted, and the distortion becomes conspicuous when the camouflage portion 88 is exposed.

However, like the camouflage panel 1 according to the present invention, by connecting the display device 50 itself to the main body panel portion 10, the display device 50 can also be used as a reinforcing structural material of the camouflage panel 1, and a plurality of camouflage panels 1 can be used as the camouflage portion 88. Even if it is arranged, the camouflage portion 88 without distortion can be formed. Further, since the display device 50 is directly fixed to the camouflage panel 1, there is no gap between the camouflage panel 1 and the display device 50. That is, the surface of the camouflage panel 1 and the display surface 50D of the display device 50 can be maintained in close contact with each other.

Although the case where the display device 50 is fixed is shown here, the accessories that can be fixed to the camouflage panel 1 are not limited to the display device 50. For example, an article such as a speaker or an operation button may be fixed. Further, an opening for that purpose may be provided.

Next, refer to FIG. 6 (a) and 6 (b) are cross-sectional views of the periphery of the camouflage portion 88 cut in a direction perpendicular to the vehicle traveling direction. Below the side structure 84, the window glass 84ba of the window portion 84b is arranged. Above the window glass 84ba, a camouflage portion lower end member 88b fixed to the side structure 84 is arranged. The camouflage portion 88 is composed of a camouflage panel 1, a camouflage portion upper end member 88a and a camouflage portion lower end member 88b which follow it. An air conditioner outlet or the like may be arranged on the upper end member 88a of the camouflage portion.

The upper end member 88a of the camouflage portion is connected to the ceiling plate 80a in the vehicle. The ceiling plate 80a in the vehicle is fixed to the ceiling portion 80. On the vehicle body side, a distributor 52 that distributes electric power and signals to the display device 50 is provided. Here, the signal may include next station information, railway information, advertisements, real-time information by the Internet or wireless communication, and the like. The receiving device (not shown) for these signals is provided on the vehicle body structure side.

When attaching the camouflage panel 1 to the camouflage portion 88, the camouflage panel 1 is hooked on the camouflage panel receiver 88c provided on the camouflage portion 88 of the vehicle with the upper end hook 22 and temporarily fixed. FIG. 7A shows an enlarged view of a state in which the camouflage panel 1 is hooked on the camouflage panel receiver 88c (FIG. 6A).

The camouflage panel receiver 88c is fixed or welded to the side structure 84 or the ceiling portion 80. A receiving groove 88ca having a semicircular cross section is provided at the tip of the camouflage panel receiving 88c. The receiving groove 88ca is fitted with a convex return 22b having a spherical cross section of the upper end hook 22. It can be said that the receiving groove 88ca is stored in the hook pocket 22c.

Since both the receiving groove 88ca and the convex return 22b have a spherical cross section, the camouflage panel 1 is swingably hooked with the upper end hook 22 as the pivot axis. Further, since the claw rib 24 is arranged so as to be close to the outer peripheral surface of the receiving groove 88ca, even if an accidental force is applied to the camouflage panel 1 from below, the camouflage panel 1 is disengaged from the camouflage panel receiving 88c. , Will not fall.

As shown in FIG. 6A, the camouflage panel 1 is hooked on the camouflage panel receiver 88c, and the display device 50 is wired. When the wiring is completed, the lower plate portion 12 of the camouflage panel 1 is pushed up with the upper end hook 22 as the pivot, and the set screw 16 is rotated. Along with the rotation of the set screw 16, the locking tongue piece 18 rotates, and the lower end member 88b of the camouflage portion and the lower end of the camouflage panel 1 are fixed.

That is, the camouflage panel 1 is fixed by the upper end hook 22 and the locking tongue piece 18. FIG. 6B shows a state in which the lower plate portion 12 of the camouflage panel 1 is fixed. Further, FIG. 7B shows an enlarged view of the upper end hook 22 at that time. As described above, the camouflage panel 1 according to the present invention can be attached to and detached from the camouflage portion 88 very easily. Further, in the railway vehicle structure on which the camouflage panel 1 according to the present invention is mounted, a large number of display devices 50 can be arranged on a camouflage portion 88 in the vehicle on a plane without distortion.

The camouflage panel and the railroad vehicle structure on which the camouflage panel according to the present invention is mounted can be suitably used for a vehicle in which a large number of display devices are arranged in the camouflage portion.
