In the above-mentioned conventional technique, in order to prevent the contact end side of the second edge member from being rolled up, generally, when manufacturing a railway vehicle, the contact end in the longitudinal direction of the second edge member is in contact with the first edge member. The projecting portion protruding from the abutting end is positioned on the side opposite to the vehicle interior space of the first edge member. However, in order to bring the contact end of the second edge member into contact with the first edge member, after forming the second edge member longer in consideration of manufacturing error and the like, the protruding portion is formed by using a cutting tool such as a chisel. The method of removing a part of the contact end side while avoiding the above has a problem that it is difficult to adjust the length of the second edge member.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a railway vehicle capable of easily adjusting the length of the second edge member and a method for manufacturing the same.

The second central end 49 and the lower end of the lower edge member 42 are planes perpendicular to the longitudinal direction of the lower edge member 42. The lower edge surface member 42 has the same cross-sectional shape over the entire length in the longitudinal direction. The fact that the cross-sectional shape is the same means that the cross-sectional shape of the portion excluding the through hole 42c into which the countersunk screw 46 described later is inserted is the same.

The lower edge surface member 42 includes an exposed portion 42a facing the passenger compartment 2 side and a plate-shaped mounting portion 42b integrally molded with the exposed portion 42a. The exposed portion 42a is a member that smoothly connects the corners of the first interior panel 21 and the second interior panel 22.

The exposed portion 42a is overlapped with the surface of the first interior panel 21 and the second interior panel 22 on the guest room 2 side along the side edge edges 24 and 27. Then, the vicinity of the side edge 24 of the first interior panel 21 is sandwiched between the inner frame 31 and the first contact surface 31a. Thereby, the movement of the first interior panel 21 in the vicinity of the side edge 24 in the rail direction can be restricted.

The mounting portion 42b is a portion that extends from the exposed portion 42a toward the internal frame 31 through between the side edge 24 of the first interior panel 21 and the side edge 27 of the second interior panel 22. .. The mounting portion 42b is inserted between the spacer 31d and the second interior panel 22. Then, it is inserted so that the vicinity of the side edge 27 of the second interior panel 22 is sandwiched between the mounting portion 42b and the exposed portion 42a. Thereby, the movement of the second interior panel 22 in the vicinity of the side edge 27 in the direction of the sleepers can be restricted.

The mounting portion 42b is provided with a through hole 42c into which a countersunk screw (fastening member) 46 to be mounted on the inner frame 31 is inserted. The mounting portion 42b is fixed to the inner frame 31 via the countersunk screw 46 inserted into the through hole 42c. The through hole 42c is formed in a conical shape into which the head of the countersunk screw 46 fits. As a result, the head of the countersunk screw 46 can be prevented from interfering with the second interior panel 22 inserted between the mounting portion 42b and the exposed portion 42a. Further, the countersunk screw 46 can be hidden from the guest room 2 side by the second interior panel 22.

The edge member 40 will be further described with reference to FIGS. 2 (a), 3 (a), and 3 (b). FIG. 2A is a cross-sectional view of the railway vehicle 10 on the line IIa-IIa of FIG. FIG. 3A is a front view of the edge member 40. FIG. 3B is a side view of the edge member 40 as viewed from the direction of arrow IIIb in FIG. 3A.

As shown in FIGS. 3A and 3B, the lower edge member 42 is provided with a plurality of through holes 42c at intervals in the longitudinal direction. The plurality of through holes 42c are provided corresponding to the positions where the plurality of countersunk screws 46 are attached to the inner frame 31. That is, a predetermined position where the lower edge surface member 42 is attached to the inner frame 31 is predetermined.

The edge member 40 has the same cross-sectional shape over the entire length in the longitudinal direction. That is, the cross-sectional shape perpendicular to the longitudinal direction of the upper edge member 41 is formed to be the same as the cross-sectional shape perpendicular to the longitudinal direction of the lower edge member 42. The upper edge member 41 protrudes from a contact portion 41a facing the passenger compartment 2 (see FIG. 1 and the like) side, a plate-shaped base portion 41b integrally molded with the contact portion 41a, and a part of the contact end 43. The protrusion 45 is provided.

The cross-sectional shape of the abutting portion 41a is formed to be the same as the cross-sectional shape of the exposed portion 42a shown in FIG. 2B over the entire length in the longitudinal direction (from the abutting end 43 to the first central end 44). .. Further, the contact portion 41a is overlapped with the surface of the first interior panel 21 and the second interior panel 22 on the passenger compartment 2 side, and is placed between the contact portion 41a and the first contact surface 31a of the internal frame 31, similarly to the exposed portion 42a. The vicinity of the side edge 24 of the first interior panel 21 is sandwiched.

The base portion 41b is a part from the contact end 43 to the first central end 44. The cross-sectional shape of the base portion 41b is formed to be the same as the cross-sectional shape of the mounting portion 42b shown in FIG. 2B over the entire length in the longitudinal direction. Like the mounting portion 42b, the base portion 41b is inserted between the spacer 31d and the second interior panel 22, and the vicinity of the side edge 27 of the second interior panel 22 is inserted between the abutting portion 41a. There is. The base 41b is not provided with a through hole 42c into which a countersunk screw 46 attached to the inner frame 31 is inserted.

The projecting portion 45 is a plate-shaped portion projecting from the contact end 43 so as to extend the base portion 41b in the longitudinal direction, and is integrally molded with the base portion 41b. An insertion hole 45a is formed in the protruding portion 45 so as to penetrate in the plate thickness direction. The cross-sectional shape of the protruding portion 45 is the same over the entire length of the edge member 40 in the longitudinal direction, and is the same as the cross-sectional shape perpendicular to the longitudinal direction of the base portion 41b. The fact that the cross-sectional shape of the protruding portion 45 and the cross-sectional shape of the base portion 41b are the same indicates that the cross-sectional shape of the portion excluding the insertion hole 45a is the same.

As shown in FIG. 2A, the protruding portion 45 protruding from the contact end 43 (see FIG. 1) of the edge member 40 is located on the inner frame 31 side of the upper edge member 34. As a result, the contact end 43 of the edge member 40 can be prevented from being rolled up toward the passenger compartment 2.

More specifically, the protrusion 45 is inserted between the second interior panel 22 on which the upper edge member 34 is superposed on the surface on the passenger compartment 2 side and the spacer 31d. The upper edge member 34, the second interior panel 22, and the protrusion 45 are attached to the inner frame 31 by a screw 47 penetrating the insertion hole 45a of the upper edge member 34, the second interior panel 22, and the protrusion 45.

Next, a method of manufacturing the railway vehicle 10 will be described with reference to FIGS. 1 to 3 (b). First, the first interior panel 21 is superposed on the passenger compartment 2 side of the internal frame 31 or the like fixed to the vehicle structure such as the underframe 11 or the roof structure 13.

After that, the attachment portion 42b of the lower edge surface member 42 is attached to the inner frame 31 using the countersunk screw 46 (attachment step), and the exposed portion 42a of the lower edge surface member 42 and the first contact surface 31a of the inner frame 31 The vicinity of the side edge 24 of the first interior panel 21 is sandwiched between the two. Next, the side edge 27 of the second interior panel 22 is inserted between the exposed portion 42a and the mounting portion 42b. Then, the regulation plate portion 33b of the bracket 33 is overlapped with the surface of the second interior panel 22 on the passenger compartment 2 side, and the mounting plate portion 33a of the bracket 33 is screwed to the inner frame 32. After that, the lower edge member 36 is superposed on the guest room 2 side of the lower edge 25 of the first interior panel 21 and the second interior panel 22, and the lower edge member 36 is attached to the inner frame 31 or the like.

Next, an adhesive is applied to the first central end 44 of the upper edge member 41, the base portion 41b and the protruding portion 45 are inserted between the spacer 31d and the second interior panel 22, and the first central end 44 is lowered. The side edge member 42 is brought into contact with the second central end 49 and adhered. After that, the first interior panel 21 and the second interior panel are formed along the upper edge 23 so that the contact edge 34a of the upper edge member 34 comes into contact with the contact end 43 of the contact portion 41a of the upper edge member 41. The upper edge member 34 is superposed on the surface of 22 on the guest room 2 side. Finally, the upper edge member 34, the second interior panel 22, and the upper edge surface member 41 are fixed to the inner frame 31 with screws 47 to manufacture the railway vehicle 10.

Here, in the longitudinal direction between the second central end 49 of the lower edge member 42 mounted (positioned) at a predetermined position of the inner frame 31 by the mounting step and the abutting edge 34a of the upper edge member 34. The interval L1 may vary due to manufacturing errors of each part of the vehicle structure, mounting errors of the upper edge member 34, the lower edge surface member 42, the lower edge member 36, and the like. It is necessary to appropriately adjust the length L2 of the contact portion 41a of the upper edge surface member 41 fitted between the second central end 49 and the contact edge 34a according to the manufacturing error and the like.

A method of manufacturing the upper edge surface member 41 and a method of adjusting the length L2 of the upper edge surface member 41 will be described with reference to FIGS. 3 (a) to 4 (b). FIG. 4A is a top view of the profile 48, and FIG. 4B is a side view of the profile 48 as viewed from the direction of arrow IVb of FIG. 4A. In FIGS. 4A and 4B, parallel lines are hatched at the portions of the profile 48 that are removed in the removal step and the forming step described later.

As shown in FIGS. 4A and 4B, a profile 48 having the same cross-sectional shape over the entire length in the longitudinal direction is prepared. The profile 48 is a member that serves as an upper edge member 41, and is formed by extrusion molding. The cross-sectional shape of the profile 48 is set to be the same as the cross-sectional shape of the upper edge member 41 (contact portion 41a and base portion 41b). In FIGS. 4A and 4B, portions of the profile 48 having the same cross-sectional shape as the abutting portion 41a and the base portion 41b are designated by the same reference numerals as the abutting portion 41a and the base portion 41b. Further, in FIG. 4A, the boundary between the portion corresponding to the contact portion 41a and the portion corresponding to the base portion 41b is shown by a virtual line A.

In order to manufacture the upper edge member 41, first, a portion of the profile 48 corresponding to the contact portion 41a is machined from one end in the axial direction (upper end of the paper surface in FIG. 4B) to the virtual line B. Removed by (forming process). As a result, the portion corresponding to the virtual line B becomes the contact end 43, and the portion corresponding to the base portion 41b that is not removed from one end in the axial direction of the profile 48 becomes the protruding portion 45. In this way, the upper edge member 41 in which the protruding portion 45 protrudes from the contact end 43 can be easily manufactured.

The lower edge member 42 and the profile 48 have the same configuration except that the lengths are different. Therefore, the profile 48 can be formed by using a molding die that forms the lower edge member 42 by extrusion molding and forms the lower edge member 42. Further, the lower edge surface member 42 can be formed to be longer by extrusion molding, the lower edge surface member 42 can be divided in the longitudinal direction, and a part of the divided portion can be used as a profile 48. As described above, if there is a molding die for the lower edge surface member 42, the molding die for manufacturing the upper edge surface member 41 can be eliminated.

The insertion hole 45a provided in the protruding portion 45 may be provided in advance in the profile 48 before the forming step, or may be provided in the protruding portion 45 after the forming step. Further, in this forming step, the upper edge member 41 (contact) from the contact end 43 to the first central end 44 rather than the distance L1 between the lower edge member 42 and the upper edge member 34, which varies due to manufacturing errors and the like. The length L3 of the portion 41a) is formed to be sufficiently long.

Next, the distance L1 between the second central end 49 of the lower edge surface member 42 attached to the predetermined position of the inner frame 31 by the attachment step and the contact edge 34a of the upper edge member 34 when attached to the inner frame 31. To measure. The upper edge member 34 may be temporarily fixed to the inner frame 31 and the interval L1 may be measured, and the first interior panel 21 so that the position of the contact edge 34a when the upper edge member 34 is attached to the inner frame 31 can be known. The distance between the mark provided in the above and the second central end 49 may be measured as the interval L1.

Based on the measured interval L1, the upper edge member 41 after the forming step in which the length L3 of the upper edge member 41 is formed sufficiently longer than the interval L1 is predetermined in the longitudinal direction from the first central end 44. Remove only the length (removal step). Specifically, the upper edge surface member 41 is removed from the first central end 44 to the virtual line C by grinding or cutting. After the removal step, the portion corresponding to the virtual line C becomes the new first central end 44. In the removing step, a part of the upper edge surface member 41 is removed so that the length L2 of the upper edge surface member 41 from the contact end 43 to the new first central end 44 is the same as the interval L1.

According to the railway vehicle 10 and its manufacturing method as described above, the protrusion 45 protrudes from the contact end 43 while the contact end 43 is in contact with the contact edge 34a of the upper edge member 34, and the inner frame 31 The edge surface member 40 fixed at a predetermined position is divided into an upper edge surface member 41 and a lower edge surface member 42 in the longitudinal direction. Here, consider a case where the edge surface member 40 is not divided into an upper edge surface member 41 and a lower edge surface member 42.

In this case, in order to bring the contact end 43 of the edge member 40 fixed at a predetermined position of the inner frame 31 into contact with the contact edge 34a, after forming the edge member 40 longer in consideration of manufacturing error and the like. , It is necessary to remove a part of the contact end 43 while avoiding the protruding portion 45 by using a cutting tool such as a chisel. In such a method, not only is it difficult to adjust the length of the edge member 40, but it is also difficult to form the contact end 43 neatly, and the appearance of the edge member 40 from the guest room 2 is deteriorated. Further, it is difficult to adjust the length of the edge member 40, which is only slightly shorter than the distance from the underframe 11 to the middle ceiling 14, in the guest room 2.

On the other hand, in the present embodiment, since the edge surface member 40 is divided into the upper edge surface member 41 and the lower edge surface member 42, the lower edge surface member 42 is fixed at a predetermined position of the inner frame 31. After that, the length L2 of the upper edge member 41 can be adjusted according to the distance L1 between the second central end 49 of the lower edge member 42 and the abutting edge 34a of the upper edge member 34. Since the length L2 of the upper edge member 41, which is relatively short, can be adjusted in this way, the length of the edge member 40 can be easily adjusted even in the cabin 2.

Further, when the length L3 of the upper edge surface member 41 from the contact end 43 to the first central end 44 is longer than the distance L1 between the second central end 49 and the contact edge 34a, the upper edge surface member 41 The length L2 of the upper edge member 41 (the length of the edge member 40) can be adjusted by removing a predetermined length from the first central end 44. Since it is easier to remove a predetermined length from the first central end 44, which is a plane perpendicular to the longitudinal direction, as compared with removing a predetermined length from the contact end 43 while avoiding the protruding portion 45, the upper side. The length L2 of the upper edge member 41 can be easily adjusted so that the contact end 43 and the first central end 44 of the edge member 41 abut and adhere to the contact edge 34a and the second central end 49, respectively. ..

Further, it is not necessary to form the contact end 43 in the cabin 2 while avoiding the protruding portion 45, and the contact end 43 can be neatly formed in advance by machining or the like. Then, the entire surface of the first central end 44, which is a plane perpendicular to the longitudinal direction, is scraped to adjust the length L2 of the upper edge member 41. Therefore, even if the first central end 44 is scraped in the cabin 2, the first center The end 44 can be formed neatly. Therefore, the appearance of the edge member 40 from the guest room 2 can be improved.

In the forming step, the length L3 of the upper edge member 41 from the contact end 43 to the first central end 44 is formed sufficiently longer than the interval L1 that varies due to manufacturing error or the like, and the interval L1 is set by the removing step. The length L2 of the upper edge member 41 is the same. As a result, it is possible to prevent the length L2 of the upper edge surface member 41 that fits between the contact edge 34a and the second central end 49 from becoming insufficient.

A plurality of fastening members (counter screws 46) for fixing the edge member 40 to the inner frame 31 are inserted, except for the insertion hole 45a into which the screw 47 to be fastened together with the upper edge member 34 is inserted. All the through holes 42c are provided in the lower edge surface member 42, and are not provided in the upper edge surface member 41. As a result, the position of the contact end 43 is specified with respect to the upper edge member 34 and the inner frame 31, and the position of the first central end 44 can be adjusted.

Therefore, the distance from the lower edge surface member 42 attached by the attachment step to the screw 47 (the insertion hole of the second interior panel 22 through which the screw 47 penetrates) is measured, and the insertion hole 45a to the first center according to the distance. By adjusting the length of the upper edge member 41 up to the end 44, the upper edge member 41 (contact portion 41a) can be fitted between the contact edge 34a and the second central end 49. Therefore, the length of the upper edge surface member 41 can be adjusted more easily.

The first interior panel 21 and the second interior panel 22 are fixed to the inner frames 31 and 32 by the upper edge member 34, the edge surface member 40, the lower edge member 36 and the bracket 33 which are overlapped on the surface on the passenger compartment 2 side. There is. Further, after fixing the lower edge member 42 of the edge member 40 stacked along the side edge 24 of the first interior panel 21 to the inner frame 31 with the countersunk screw 46, the countersunk screw 46 is fixed from the guest room 2. The side edge 27 of the second interior panel 22 is inserted into the lower edge member 42 so as to hide it. After that, the bracket 33 provided along the side edge 28 of the second interior panel 22 is screwed to the internal frame 32 at a position invisible from the cabin 2. In this way, the fastening member (counter-screw 46, etc.) for fixing the first interior panel 21, the second interior panel 22, the edge member 40, and the bracket 33 can be hidden from the guest room 2, and can be hidden from the guest room 2. You can improve the appearance of.

In a state where the second interior panel 22 is fixed to the internal frames 31 and 32 by the lower edge member 42 and the bracket 33, the upper edge surface of the first interior panel 21 and the second interior panel 22 on the passenger compartment 2 side surface. Since the members 41 are stacked, the upper edge surface member 41 cannot be fixed to the inner frame 31 by the countersunk screws 46 hidden by the second interior panel 22. However, in the present embodiment, the upper edge member 41 does not have a plurality of through holes 42c into which the fastening member (counterscrew 46 or the like) is inserted, except for the insertion hole 45a provided in the protrusion 45. Therefore, the fastening member can be hidden from the cabin 2 over the entire length from the contact end 43 of the edge member 40 exposed to the cabin 2 side to the end on the lower edge member 36 side.

Further, the protruding portion 45 of the upper edge surface member 41 is fixed to the inner frame 31 by the screw 47, and the upper edge surface member is attached to the second central end 49 of the lower edge surface member 42 attached to the inner frame 31 by the countersunk screw 46. The first central end 44 of 41 is adhered. As a result, the upper edge surface member 41 can be firmly fixed to the inner frame 31, and rattling of the upper edge surface member 41 can be suppressed.
