In recent years, in order to diversify the provision of information to passengers, a display device may be provided in the passenger compartment, but if a display panel can be provided in the window area, it is easy for passengers to see and space efficiency is good. However, the thickness of the window glass including the display panel is larger than the thickness of the existing descending window glass. Therefore, if an attempt is made to replace the descending window with a display window in an existing railroad vehicle, the vehicle body needs to be significantly modified.

Therefore, an object of the present invention is to make it possible to easily replace the descending window of an existing railway vehicle with a display window without requiring a major modification of the vehicle body.

The interchangeable display window of the railroad vehicle according to one aspect of the present invention is a display that can be replaced with a descending window that is slidably attached up and down with respect to a guide groove formed at the side edge of the window opening of the vehicle body of the railroad vehicle. A window body including a display panel thicker than the width of the guide groove in the window thickness direction, and a frame body arranged along the outer edge of the window body and connected to the window body. The frame body is thinner than the maximum width of the side frame portion in the window thickness direction and the side frame portion facing the side end portion of the window body, and the guide projects laterally from the side frame portion. It has a side convex portion to be inserted into the groove.

According to the above configuration, since the window body includes a thick display panel, even if the side frame portion is larger than the width of the guide groove in the window thickness direction, the side convex portion that can be inserted into the guide groove is the side frame. Since it is provided in the portion, the display window can be attached to the guide groove of the vehicle body. Therefore, the descending window of an existing railroad vehicle can be easily replaced with a display window without requiring a major modification of the vehicle body.

According to the present invention, the descending window of an existing railway vehicle can be easily replaced with a display window without requiring a major modification of the vehicle body.

Hereinafter, embodiments will be described with reference to the drawings. The concept of the direction used in the following description is based on the direction in which the window opening is viewed from inside the vehicle.

(First Embodiment)
FIG. 1 is a side view of the side structure 3 of the vehicle body 2 of the railway vehicle 1 and its vicinity as viewed from the inside of the vehicle. As shown in FIG. 1, a door opening 4 and a window opening 5 are formed in the side structure 3 constituting the vehicle body 2 of the railway vehicle 1. A side sliding door 6 is provided in the door opening 4. The window opening 5 was originally provided with a descending window (not shown) that can slide up and down, but the descending window is removed and a display window 10 described later is attached.

On the lower side of the window opening 5 of the side structure 3, a storage portion 3a is formed in which the lower portion of the descending window is housed when the descending window is lowered to open the window opening 5. In the side structure 3, a guide groove 3c (see FIG. 3) described later is formed on the side edge portion 3b of the window opening 5, and an engagement groove 3e (see FIG. 5) is formed on the upper edge portion 3d of the window opening 5. A slit 3g (see FIG. 6) communicating with the storage portion 3a is formed in the lower edge portion 3f of the window opening 5. Inside the vehicle of the side structure 3, a seat 7 is provided below the window opening 5. In the present embodiment, the seat 7 is a long seat arranged along the longitudinal direction of the vehicle, but a cross seat, a semi-cross seat, or the like may be used, and the arrangement of the seats is not limited thereto.

FIG. 2 is a side view of the display window 10 according to the first embodiment as viewed from the inside of the vehicle. As shown in FIG. 2, a display window 10 is attached to the window opening 5 in place of the descending window. The display window 10 includes a frame body 11 and a window body 12. The frame body 11 has a square frame shape and is arranged along the outer edge of the window body 12. The frame body 11 includes a pair of side frame portions 21 facing the left and right side ends of the window body 12 in the left-right direction, an upper frame portion 23 facing the upper end portion of the window body 12 in the vertical direction, and the window body 12. The lower end portion has a lower frame portion 25 facing in the vertical direction.

The window body 12 is connected to the frame 11 in a state of being surrounded by the frame 11. In the present embodiment, the window main body 12 is composed of a fixed window 31 and an inwardly folded window 32. The fixed window 31 is arranged in the lower region (first region) of the space surrounded by the frame 11, and the inner folding window 32 is arranged in the upper region (second region) of the space surrounded by the frame 11. ing. The position where the fixed window 31 and the inwardly folded window 32 are arranged is not limited to the upper region and the lower region as long as the space is surrounded by the frame body 11.

The fixed window 31 is fixed to the side frame portion 21. The inwardly folded window 32 is rotatably connected to the side frame portion 21. Specifically, the frame body 11 has an intermediate frame portion 26 that divides the space surrounded by the frame body 11 into the lower region and the upper region, and the lower end portion of the inner folding window 32 becomes the intermediate frame portion 26. It is rotatably connected. That is, by rotating the lower end portion of the inner folding window 32 around the axis in the left-right direction, the inner folding window 32 opens and operates so that the upper end portion of the inner folding window 32 falls inside the vehicle. In this way, since the passenger compartment in the vehicle can be ventilated by the inwardly folded window 32, it is not necessary to provide a ventilation port or a ventilation device in the vehicle body 2, and the labor and cost required for window replacement can be reduced.

A balancer 8 is arranged in the storage portion 3a. The balancer 8 is for the descending window and is not used after being replaced with the display window 10. The balancer 8 has a support portion 8a that supports the descending window from below, an arm portion 8b whose one end is connected to the support portion 8a, and an arm portion 8b that is connected to the other end of the arm portion 8b to rotate the arm portion 8b. Has a main body 8c that imparts resistance (for example, repulsive force and damping force) to the window. The balancer 8 prevents the descending window from vigorously descending when the descending window is housed in the storage portion 3a.

FIG. 3 is a sectional view taken along line III-III of FIG. As shown in FIG. 3, a guide groove 3c that is opened toward the window opening 5 and extends in the vertical direction is formed in the side edge portion 3b of the window opening 5 of the side structure 3. Specifically, the guide groove 3c is formed by fixing the plate P1 having a Z-shaped cross section and the plate P2 having a straight cross section to each other with the fastener B. The cross-sectional shapes of the plates P1 and P2 are not limited to these, and for example, a plate having an L-shaped cross section may be fixed with a fastener to form a guide groove 3c. The side frame portion 21 has a holding portion 21a having a U-shaped cross section for holding the side end portion of the fixed window 31. The fixed window 31 is a square plate-shaped transparent plate (for example, a glass plate), but may be a display window.

The side frame portion 21 is provided with a side convex portion 22 protruding laterally from a part of the end surface on the outer side in the left-right direction of the holding portion 21a. The holding portion 21a and the side convex portion 22 are integrally formed with each other. The side convex portion 22 is inserted into the guide groove 3c. In the window thickness direction (normal direction of the window body 12), the width T1 of the side convex portion 22 is equal to or less than the width T0 of the guide groove 3c. In the window thickness direction, the width T1 of the side convex portion 22 is thinner than the maximum width T2 (width of the holding portion 21a) of the side frame portion 21. The side convex portion 22 is provided at a position biased toward the inside of the vehicle with respect to the side frame portion 21.

FIG. 4 is a sectional view taken along line IV-IV of FIG. As shown in FIG. 4, the inwardly folded window 32 includes a square plate-shaped main portion 41 and a bezel portion 42 having a U-shaped cross section that holds the peripheral edge portion of the main portion 41. The main portion 41 has a display panel 51 and a pair of transparent plates 52 that sandwich the display panel 51 from the outside and the inside of the vehicle. The display panel 51 is a flat image display device, for example, a liquid crystal panel or an organic EL panel, but the type of panel is not particularly limited. The transparent plate 52 is formed of, for example, a transparent resin or glass.

In the present embodiment, since the area of the display panel 51 is smaller than the area of the transparent plate 52, the transparent spacer 53 is arranged in the gap between the pair of transparent plates 52 where the display panel 51 does not exist. .. With such a configuration, the display panel 51 is stably held even if the vibration of the railway vehicle 1 during traveling is transmitted to the display window 10. The main portion 41 may have a configuration in which the area of the display panel 51 is the same as the area of the transparent plate 52 and the spacer 53 is eliminated.

The side frame portion 21 has a regulating portion 21b having an L-shaped cross section that regulates the displacement of the inner folding window 32 to the outside of the vehicle. The side frame portion 21 is provided with a side convex portion 22 that projects laterally from the regulating portion 21b and is inserted into the guide groove 3c. The regulating portion 21b and the side convex portion 22 are integrally formed with each other. In the window thickness direction of the inwardly folded window 32, the thickness T3 of the side end portion of the inwardly folded window 32 is thicker than the width T0 of the guide groove 3c. In the window thickness direction of the inwardly folded window 32, the width T1 of the side convex portion 22 is thinner than the maximum width T2 (width of the regulation portion 21b) of the side frame portion 21. The width T1 of the side convex portion 22 is thinner than the thickness T3 of the side end portion of the inwardly folded window 32. The side convex portion 22 is provided at a position biased toward the inside of the vehicle with respect to the side frame portion 21, and the inwardly bent window 32 is arranged biased toward the outside of the vehicle with respect to the guide groove 3c. The side convex portion 22 extends continuously in the vertical direction from the upper portion to the lower portion of the side frame portion 21, but may be provided discontinuously in the vertical direction. Further, although the side convex portion 22 is integrally formed with the side frame portion 21, it may be formed separately and fixed to each other.

FIG. 5 is a sectional view taken along line VV of FIG. As shown in FIG. 5, the upper edge 3d of the window opening 5 of the side structure 3 is formed with an engaging groove 3e that is opened toward the window opening 5 and extends in the left-right direction. The upper frame portion 23 has a regulating portion 23a having an L-shaped cross section that regulates the displacement of the inner folding window 32 to the outside of the vehicle. The upper frame portion 23 is provided with an upper convex portion 24 that projects upward from the regulating portion 23a and is inserted into the engaging groove 3e. The upper convex portion 24 is detachably fixed to the upper frame portion 23 by a fastener B. The upper convex portion 24 may be connected to the upper frame portion 23 so as to be slidable up and down instead of being fixed by the fastener B.

FIG. 6 is a sectional view taken along line VI-VI of FIG. As shown in FIG. 6, the lower edge portion 3f of the window opening 5 of the side structure 3 is formed with a slit 3g extending in the left-right direction by communicating the window opening 5 with the storage portion 3a. The lower frame portion 25 includes a holding portion 25a for holding the lower end portion of the fixed window 31, an inner leg portion 25b protruding downward from the inside of the vehicle of the holding portion 25a, and an outer leg protruding downward from the outside of the vehicle of the holding portion 25a. It has a part 25c. The inner leg portion 25b is inserted into the slit 3g, and the outer leg portion 25c lands on the lower edge portion 3f. The balancer 8 is separated downward from the lower frame portion 25 and is not used. The lower frame portion 25 is not limited to this form, and may be another form as long as it is supported from below by the lower edge portion 3f of the side structure 3.

According to the configuration described above, since the window body 12 includes the display panel 51 having a thickness larger than the width T0 of the guide groove 3c, the side frame portion 21 is larger than the width T0 of the guide groove 3c in the window thickness direction. Even so, since the side convex portion 22 that can be inserted into the guide groove 3c is provided in the side frame portion 21, the display window 10 can be attached to the guide groove 3c of the vehicle body 2. Therefore, the descending window of the existing railway vehicle 1 can be easily replaced with the display window 10 without requiring a major modification of the vehicle body.

Further, the side convex portion 22 is provided at a position biased toward the inside of the vehicle with respect to the side frame portion 21, and the window body 12 including the thick display panel 51 is unevenly distributed not inside the vehicle but outside the vehicle. , It is possible to prevent the space inside the car from being reduced. Further, when assembling the display window 10 to the vehicle body 2, the frame 11 can be easily arranged in the window opening 5 by removing or sliding the upper convex portion 24 with respect to the upper frame portion 23. After that, by attaching the upper convex portion 24 to the upper frame portion 23 or sliding it upward, the upper convex portion 24 can be engaged with the engaging groove 3e of the upper edge portion 3d of the window opening 5.

Also in this embodiment, since the area of the display panel 151 is smaller than the area of the transparent plate 152, the transparent spacer 153 is arranged in the gap between the pair of transparent plates 152 where the display panel 151 does not exist. .. The upper window 131 may have a configuration in which the area of the display panel 151 is the same as the area of the transparent plate 152 and the spacer 153 is eliminated.

As shown in FIG. 9, the thickness T4 of the upper window 131 is thicker than the width T0 of the guide groove 3c in the window thickness direction. The side frame portion 121 of the frame body 111 has an upper holding portion 121a having a U-shaped cross section for holding the side end portion of the upper window 131. The side frame portion 121 is provided with a side convex portion 122 projecting laterally from the upper holding portion 121a. The upper holding portion 121a and the side convex portion 122 are integrally formed with each other. The side convex portion 122 is inserted into the guide groove 3c. In the window thickness direction (normal direction of the window body 112), the width T1 of the convex portion 122 is thinner than the maximum width T2 (width of the upper holding portion 121a) of the side frame portion 121. The width T1 of the side convex portion 122 is thinner than the thickness T4 of the upper window 131. The side convex portion 122 is provided at a position biased toward the inside of the vehicle with respect to the side frame portion 121, and the upper window 131 is arranged biased toward the outside of the vehicle with respect to the guide groove 3c.
