Each term does not limit the technical scope of the present invention, and while considering the best mode for carrying out the invention, replaces, deletes, or further The technical scope of the present invention can also include those to which the constituent elements are added.

(1) A light shielding device for a side window provided on a window frame of a vehicle body of a railroad vehicle, wherein a pair of rails are arranged on the window frame so as to sandwich the side window in a front view of the side window. two end bar members extending between the pair of rail members and having both ends engaged with the rail members so as to be movable along the pair of rail members; and the two end bars. A member held between the two end bar members and extending to connect between the pair of rail members, the two end bar members extending along the pair of rail members at both ends of the rail member. a sheet-like member having a size to cover at least the side window together with or alone with the two end bar members in a state spaced apart from the upper part of the end bar, wherein the sheet-like member includes the two end bar members; A light shielding device that is pleated so as to form a plurality of folds parallel to the extending direction of a member.

The light shielding device according to this section includes a pair of rail members, two end rod members, and a sheet-like member. In the front view of the side window from the empty, they are arranged to face each other so as to sandwich the side window. That is, the pair of rail members are arranged parallel to each other, for example, along the longitudinal direction of the vehicle body or the vertical direction of the vehicle body. Each of the two end bar members extends between the pair of rail members and engages the rail member at both ends so as to be movable along the pair of rail members. That is, each end bar member is held by a pair of rail members with one end engaged with one rail member and the other end engaged with the other rail member. At this time, one end and the other end of the end bar member and the rail member are engaged in such a state that the end bar member can move along the rail member, and the two end bar members are connected to the pair of rail members. arranged parallel to each other.

On the other hand, the sheet-shaped member is not directly held by the rail members, but is held by the two end bar members arranged parallel to each other between the pair of rail members as described above. held between The sheet-shaped member is large enough to cover at least the side window together with or alone with the two end bar members in a state in which the two end bar members are separated along the pair of rail members to both ends of the rail members. It has a That is, the sheet-like member has a length in a direction parallel to the extending direction of the rail member, which can connect two end bar members separated to both ends of the rail member, and connects the pair of rail members. , the length in the direction parallel to the extending direction of the end bar member. When the sheet-like member is spread by the two end rod members spaced apart in this way, it is arranged inside the vehicle body so as to cover the side window. Furthermore, the sheet member is pleated so that a plurality of folds are formed parallel to the extending direction of the two end bar members. Therefore, when the two end rod members approach each other, they contract so as to be folded between the two end rod members.

That is, in the light shielding device according to this section, the side window is covered with the spread sheet-like member by separating the two end rod members, and the two end rod members are located at one end of the rail member. The sheet-like member is contracted between the two end bar members on one end side of the rail member by being brought to the side of the rail member. In this way, while shielding the side windows as necessary, unlike the conventional light shielding device, a spring or the like for winding up the sheet-like member is not used, and the sheet-like member is engaged with the rail member. Since members and the like are not required, the weight of the light shielding device can be reduced. Furthermore, since the entire winding mechanism for winding up the sheet-like member is no longer required, the space in which the conventional winding mechanism was installed can be effectively used for other purposes.

In addition, since the two end rod members are held by a pair of rail members, even when the rail members are installed with an inclination with respect to the vertical direction of the vehicle body or when the railway vehicle is running, The sheet-shaped member held between the two end rod members is also stably held with its rocking suppressed. In addition, since the two end bar members can be moved to any position along the rail member, they can move from one end side of the rail member to the other end side or the other end of the rail member. The sheet member is opened and closed in an arbitrary direction from the side to one end side. As a result, regardless of the traveling direction of the railway vehicle (in other words, the orientation of the seat), the sheet member can be opened and closed from the direction that is easy for the user to handle.

(2) A shading device according to the above item (1), wherein the pair of rail members are spaced apart in the vertical direction of the vehicle body and installed along the longitudinal direction of the vehicle body.
In the light shielding device according to this item, a pair of rail members are installed along the longitudinal direction of the vehicle body while being separated from each other in the vertical direction of the vehicle body. That is, when the side window is viewed from the inside of the vehicle body in a front view, the pair of rail members are installed on the upper and lower portions of the window frame so as to sandwich the side window from above and below. At this time, if the side window is installed with a slight inclination with respect to the vertical direction of the vehicle body so that the upper part of the vehicle body is located inside the vehicle body rather than the lower part of the vehicle body, the same amount as the inclination A pair of rail members may be opposed to each other with an inclination to the vertical direction of the vehicle body. The two end rod members engaged with the pair of rail members are moved along the longitudinal direction of the vehicle body, and the sheet-like member held between the two end rod members is the vehicle body. It can be opened and closed along the longitudinal direction. This provides a light shielding device that opens and closes along the traveling direction of the vehicle.

At this time, if the side window is installed with a slight inclination with respect to the vertical direction of the vehicle body so that the upper part of the vehicle body is located inside the vehicle body rather than the lower part of the vehicle body, the same amount as the inclination A pair of rail members may be opposed to each other with an inclination to the vertical direction of the vehicle body. The two end rod members engaged with the pair of rail members are moved along the vertical direction of the vehicle body or along a direction slightly inclined from the vertical direction of the vehicle body. Further, the sheet-like member held between the two end bar members is opened and closed along the vertical direction of the vehicle body or along a direction slightly inclined from the vertical direction of the vehicle body. This provides a light shielding device that can be opened and closed in the vertical direction of the vehicle body.

(6) In the above item (5), each of the two end rod members has a resting structure for resting at an arbitrary position of the pair of rail members .
In the light shielding device according to this item, each of the two end rod members has a resting structure for resting at an arbitrary position on the pair of rail members. That is, since a pair of rail members are installed along the vertical direction of the vehicle body, if the two end rod members that are movably engaged with these rail members are located at positions other than the lower ends of the rail members, their own weight and There is a possibility that it will gradually move downward under the influence of vibrations of the vehicle body or the like. Therefore, for example, by providing a stationary structure that utilizes a frictional force between the rail member and the end bar member or a dedicated mechanism, the two end bar members and the sheet-like structure held by them are provided. Intentional movement of the member is prevented.

(7) In items (1) to (6) above, each of the pair of rail members has a tubular shape with a rectangular cross section in the extending direction, and a second rectangular rail member facing the other rail member.

In the light shielding device according to this item, each of the pair of rail members has a tubular shape with a rectangular cross section in the extending direction. When such a pair of rail members are installed on the window frame so as to face each other, one side (first side) of the four sides of the above-described rectangle of the rail members faces the other rail member. One side (second side) of the two sides perpendicular to the first side is positioned inside the vehicle body. Each of the pair of rail members is provided with an opening along the extending direction of the rail member near the center in the extending direction of the first side at a portion corresponding to the first side. there is That is, the cross section in the extending direction of the rail member provided with the opening is a rectangle with a part of the first side opened, and the openings provided in the pair of rail members are arranged to face each other. be. Furthermore, each of the rail members is provided with a rack rail on the inner surface of the rail member at a portion corresponding to the second side. The rack rail extends along the rail member and has a plurality of teeth aligned in its extending direction.

On the other hand, each of the two end rod members includes a tubular main body, a shaft inserted through the main body, and gears attached to both ends of the shaft. The main body is a part that holds the sheet-shaped member, and it is preferable that a handle or the like be provided to assist the user in moving the end bar member. The shaft is rotatably inserted into the main body, and in this state, both ends of the shaft protrude into the rail member from openings provided in the rail member.

In this way, while shielding the side window 54 as necessary, unlike the conventional light shielding device, a spring or the like for winding up the sheet-like member 44 is not used, and the sheet-like member 44 is held by the rail member 12 . Since there is no need for a member or the like to be engaged with the light shielding device 10, the weight of the light shielding device 10 can be reduced. Furthermore, as shown in FIG. 3(a), the whole winding mechanism 72 for winding up the sheet-like member 44 becomes unnecessary, so that the space in which the winding mechanism 72 was conventionally installed can be effectively used for other purposes. be able to. For example, in the illustrated example, the vacant space is used as a decorative portion 58 provided with a lighting 60 and a coat hook 62, and an air conditioning duct 70 is expanded and installed as indicated by the phantom lines. can also

Further, since the two end rod members 30 are held by the pair of rail members 12, the rail members 12 may be installed with an inclination with respect to the vertical direction of the vehicle body, or when the railway vehicle is running. In addition, the sheet-like member 44 held between the two end rod members 30 can also be held stably with its rocking suppressed. . In addition, since the two end bar members 30 can be moved to any position along the rail member 12, they can move from one end side of the rail member 12 to the other end side of the rail member 12. The sheet member 44 can be opened and closed in any direction from the other end side to the one end side. As a result, the sheet member 44 can be opened and closed from a direction that is easy for the user to handle, regardless of the traveling direction of the railroad vehicle (in other words, the direction of the seat).

Further, in the light blocking device 10 according to the first embodiment of the present invention, a pair of rail members 12 are installed along the longitudinal direction of the vehicle body while being separated from each other in the vertical direction of the vehicle body. That is, when the side window 54 is viewed from the inside of the vehicle body, the pair of rail members 12 are arranged on the vehicle body upper portion 50a and the vehicle body lower portion 50b of the window frame 50 so as to face each other so as to sandwich the side window 54 from above and below. be done. At this time, as shown in FIG. 3(a), the side window 54 is installed slightly inclined with respect to the vertical direction of the vehicle body so that the portion on the upper side of the vehicle body is located inside the vehicle body rather than the portion on the lower side of the vehicle body. If so, the pair of rail members 12 are installed so as to face each other with an inclination in the vertical direction of the vehicle body that is the same as the inclination. The two end rod members 30 engaged with the pair of rail members 12 are moved along the longitudinal direction of the vehicle body, and the sheet-like member held between the two end rod members 30 44 is opened and closed along the longitudinal direction of the vehicle body. Accordingly, it is possible to provide the light shielding device 10 that opens and closes along the traveling direction of the vehicle.

Further, in the light shielding device 10 according to the first embodiment of the present invention, of the pair of rail members 12 which are installed with a space in the vertical direction of the vehicle body, the rail member 12A installed on the upper side of the vehicle body is the window frame. It is installed in a recess 52 provided in the vehicle body upper portion 50a of 50. As shown in FIG. The recess 52 has a depth greater than the thickness of the rail member 12A to be installed in the vertical direction of the vehicle body, and extends in the longitudinal direction of the vehicle body. Therefore, the rail member 12A installed in the recessed portion 52 is less visible from the inside of the vehicle body, and the appearance can be improved. Furthermore, a portion of the upper end side of the end rod member 30 that engages with the rail member 12A and a portion of the upper end side of the sheet-like member 44 that extends so as to connect the pair of rail members 12 are formed into recesses 52 . will be located in As a result, movement of the portion of the upper end side of the sheet-like member 44 in the vehicle width direction within the recess 52 is restricted, so that the sheet-like member 44 can be prevented from loosening in the vehicle width direction. In particular, in the example of FIG. 3(a), since the rail member 12A is inclined so as to be positioned inside the vehicle body (left side in the drawing) relative to the rail member 12B, the sheet-like member 44 is slackened leftward in the drawing. tends to be easy. However, since a part of the upper end side of the sheet-like member 44 is located in the recess 52, even if the sheet-like member 44 is slackened to the left in the figure, the upper end side of the sheet-like member 44 is positioned in the window frame 50. Since the sheet-like member 44 is in contact with the right end portion in the drawing of the window hook 56 forming the vehicle body upper portion 50a, the sheet-like member 44 is not greatly loosened.

Further, in the light shielding device 10 according to the first embodiment of the present invention, when the table 64 is provided along the vehicle body lower portion 50b of the window frame 50, a pair of Of the rail members 12, the rail member 12B installed on the lower side of the vehicle body is installed on the upper side of the vehicle body relative to the table 64. As shown in FIG. This makes it more difficult for foreign matter to enter the rail member 12B from the upper surface of the table 64, compared to the case where the rail member 12B is installed on the lower side of the vehicle body than the table 64 or at the same height as the table 64. Therefore, intrusion of such foreign matter can be suppressed.

Also, in the light shielding device 10 according to the first embodiment of the present invention, as shown in FIG. ing. When such a pair of rail members 12 are installed on the window frame 50 so as to face each other, one side (first side) of the four sides of the above-described rectangle of the rail member 12 is positioned against the other rail member. 12, and one side (second side) of two sides perpendicular to the first side is positioned inside the vehicle body. Each of the pair of rail members 12 has an opening 14 along the extending direction of the rail member 12 near the center in the extending direction of the first side of the portion 12a corresponding to the first side. is provided. That is, the cross section in the extending direction of the rail members 12 provided with the openings 14 is a rectangle with a part of the first side opened, and the openings 14 provided in the pair of rail members 12 face each other. are placed as follows. Further, each of the rail members 12 is provided with a rack rail 18 on the inner side surface 12c of the rail member 12 at the portion 12b corresponding to the second side. The rack rail 18 extends along the rail member 12 and has a plurality of teeth 20 arranged in the extending direction (horizontal direction in FIGS. 1 and 2).

On the other hand, each of the two end rod members 30 includes a cylindrical body portion 32, a shaft portion 34 inserted through the body portion 32, and gears 36 attached to both ends 34a of the shaft portion 34. there is The body portion 32 is a portion that holds a sheet-like member 44, and is provided with a handle portion 40 (see FIG. 1) and the like for assisting the movement of the end rod member 30 by the user. The shaft portion 34 is rotatably inserted into the main body portion 32 , and both end portions 34 a of the shaft portion 34 protrude into the rail member 12 from the openings 14 provided in the rail member 12 . That is, one end portion 34a of the shaft portion 34 of each end bar member 30 protrudes inside one rail member 12 (12A), and the other end portion 34a of the shaft portion 34 of each end bar member 30 protrudes into the rail member 12 (12A). protrudes inside the other rail member 12 (12B).

It rotates as a rotating shaft and moves along the rail member 12 inside the rail member 12 . At this time, the shaft portion 34 is moved together with the main body portion 32 while being rotated with respect to the main body portion 32 together with the gear 36 . Furthermore, since both the gears 36 rotating inside the pair of rail members 12 rotate together with the shaft portion 34 , one gear 36 does not rotate behind the other gear 36 . Therefore, it is possible to smoothly move the end rod member 30 along the rail members 12 while maintaining the state of engagement with the pair of rail members 12 .

Here, as in the example of FIG. 3, when the rail member 12 is installed slightly inclined with respect to the vertical direction of the vehicle body so that the portion on the upper side of the vehicle body is located inside the vehicle body rather than the portion on the lower side of the vehicle body. mention about Even in such a case, the gear 36 arranged inside the rail member 12 is attached to the inner side surface 12c of the portion 12b corresponding to the above-described second side of the rail member 12, on which the rack rail 18 is installed. Since it is arranged obliquely, it can be engaged with the teeth 20 of the rack rail 18 without problems.
