Description

  The present invention relates to a passage inner wall structure formed in a passage such as a through-passage portion provided between vehicles constituting a knitting by connecting a plurality of vehicles, and a rail vehicle such as a monorail vehicle and a railroad vehicle including the same. .

  A through-passage portion is provided at a longitudinal end portion of a vehicle in which a plurality of vehicles such as a railway vehicle are connected to form a knitting so that a passenger can easily and safely move. As described in [Patent Document 1], a through-passage portion of a vehicle generally forms a passage space by overlapping the crossing plates installed at the vehicle ends to form a passage space above the crossing plate. A hood (belly bellows) that connects the vehicle ends and covers the periphery of the transition board is provided. The hood has the function of defining the passage space inside while absorbing the relative position and its change not only when the adjacent vehicles are aligned in a straight line but also when traveling on a curved road or while stopping. .

Overseas, as shown in [Patent Document 2], in order to improve the appearance of the through-passage part, a crossing board part that is greatly cut from the end part of the vehicle to the cabin side and an elastic wall that is convexly curved on the passage side are installed. is doing. In this structure, the bellows part becomes invisible by installing an elastic wall, but the wall support structure is complicated and heavy, and the area occupied by the through-passage part increases. It is not a welcome structure because it will decline.
JP 2003-63387 A (paragraphs [0020] to [0022], FIGS. 1 to 3) Japanese Patent No. 2903368 (paragraphs [0021] to [0030], FIGS. 1 to 6)

  In general, in domestic commuter vehicles, at present, emphasis is placed on improving the boarding rate, and sufficient consideration has not been given to comfortable interior spaces. In particular, in a through-passage portion provided between adjacent vehicles, a structure of several decades is still a mainstream structure, and a sense of incongruity with an interior portion of a vehicle that has been improved in quality has been conspicuous. In particular, the structure described in the above [Patent Document 1] has a problem of aesthetics because passengers coming and going through the passage directly see the accordion structure of the hood. It has become one.

  In the structure described in the above [Patent Document 2], there is a problem in that the through-passage portion bites into the cabin side, so that the cabin area is reduced and the mechanism constituting the inner wall is complicated and heavy. Furthermore, the manufacturing cost of the through-passage portion is also increased.

  Therefore, there is a problem to be solved in that an inner wall structure is obtained that absorbs the relative displacement generated in various forms between the vehicle ends of the connected vehicles and makes the hood invisible from the passage side.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a passage inner wall structure that can absorb relative displacements that occur in various forms and that is simply configured and that can improve the quality of the inner wall, and to connect the passage inner wall structure between vehicle ends of a vehicle. It is to provide a rail vehicle used for the part.

  The above-mentioned object is a passage inner wall structure for a passable passage, and includes a plurality of wall members made of an elastic material juxtaposed in the direction of travel of the passage, and an elastic material that connects the adjacent wall members. This can be achieved by the inner wall structure of the passage characterized by comprising the connecting member. The inner wall structure of the passage is understood as a part applied between the vehicle ends in the rail vehicle.

  According to this passage inner wall structure, for example, when applied to a connecting portion of a vehicle, relative changes occur in various forms between end portions of adjacent vehicles depending on the rails of the vehicle traveling, etc. The inner wall structure of the passage is maintained by the wall member and the connecting member made of material absorbing the relative displacement, and the passage inner wall structure prevents a passenger coming and going from seeing the bellows structure provided outside the inner wall structure. . Depending on the mode of relative displacement between the end portions of the vehicle, the connection member absorbs the displacement by elastic deformation. When the relative displacement is a tensile displacement in the passage traveling direction, the wall member is elastically deformed first, and when the relative displacement cannot be absorbed, the connecting member can be absorbed by elastic deformation.

  An embodiment of a passage inner wall structure according to the present invention will be described based on the drawings. The inner wall structure of the passage according to the present invention can be constituted by a plurality of wall members so as to cover the bellows portion on the back side and make it invisible.

  1 to 5 show an embodiment of an inner wall structure of a passage according to the present invention applied between the ends of a vehicle 1 and a vehicle 2. Usually, a connecting plate that connects the end 1a of the vehicle 1 and the vehicle end 2a of the vehicle 2 is provided with a bridge plate that connects the passages of the vehicle 1 and the vehicle 2, but is omitted in FIG. The inner wall structure of the passage according to the present invention is not directly related to the structure of the bridge plate. Hereinafter, the end of the vehicle is simply referred to as “vehicle end”.

  In FIG. 1, the connecting portion includes a crossover plate 12 (see FIG. 2) that spans between the vehicle end 1 a and the vehicle end 2 a, and a passage space that allows passengers to travel on the crossover plate 12. An accordion-shaped hood 3 surrounding the periphery is provided, and a passage on the crossing plate 12 forms a through-passage portion through which a passenger can travel between the vehicle ends 1a, 2a. This structure is the same as the conventional structure. In the present invention, on the one side of the passage above the crossover plate 12 and inside the hood 3, wall members 4, 4a and 4b are provided as a plurality of wall members, which are the main components of the inner wall structure. They are provided side by side in the direction. Similarly, on the opposite side of the hood 3 across the passage, wall members 5, 5a, 5b, which are main components of the inner wall structure, are juxtaposed in the direction of passage of the passage. In this embodiment, the wall members are convenient three wall members including a central wide main wall member 4, 5 and narrow side wall members 4a, 4b, 5a, 5b on both sides thereof. The wall members 4, 4 a, 4 b, 5, 5 a, 5 b are formed in a vertically long substantially rectangular shape when viewed from the passage side of the through-passage portion.

  Although the wall members are on both sides of the passage, in the following description, the structure of only one side of the passage will be described. On each side of the passage, wall members 4, 4a, 4b, 5, 5a, 5b and associated structures (eg, elastic members 6a, 6b, 7a, 7b, connecting members 8a, 8b, 9a, 9b) The configuration is the same.

  The wall members 4, 4 a, 4 b are formed in a cylindrical body having a height that occupies most of the height of the through-passage portion, which is slightly shorter than the height of the through-passage portion, and has an axis in the vertical direction. ing. That is, the wall members 4, 4 a, 4 b are hollow in the lateral (horizontal) cross section, and this shape is hereinafter referred to as “tubular”. The wall member 4 has an oval elliptical shape. The wall members 4 a and 4 b are also elliptical, but their major axis is smaller than the major axis of the ellipse of the wall member 4. The size of the ellipse is deformed by the tensile force. The wall members 4, 4 a and 4 b are formed of an elastic material from the same viewpoint as the hood 3 in order to cope with a change in the relative position between the vehicle ends 1 a and 2 a. The wall members 4, 4 a, 4 b can be formed by using an elastic member as a core material and covering the surface layer with an interior material for a vehicle interior, thereby improving the quality of the inner wall structure. Moreover, the inside of the cylindrical body formed with an elastic material can also be filled with compressed gas. According to such a structure, it is safe when a passenger traveling in the passage collides with the inner wall structure due to traveling on a curved road of the vehicle.

  The elasticity of the wall members 4, 4 a, 4 b is an elasticity that easily allows the cross-sectional shape of the cylindrical body to change, and the rigidity in the bending or twisting direction with respect to the longitudinal axis is the cross-sectional shape It can be made larger than the rigidity against the change of. The wall members 4, 4 a, 4 b are formed from a rubber-based material that is flame-retardant or subjected to flame-retardant treatment from the viewpoint of the above-mentioned elasticity and from the viewpoint of disaster prevention.

  Between the adjacent wall members, that is, between the wall members 4 and 4a and between the wall members 4 and 4b, the side end portions are connected to the corresponding end portions of the respective wall members and are folded in the middle. They are connected by a connecting member 8a or 8b made of a single elastic plate. The wall member 4a and the vehicle end 2a are connected by an elastic member 6a (7a), and the wall member 4b and the vehicle end 1a are connected by an elastic member 6b (7b). The elastic member 6a and the elastic member 6b are connected between the vehicle ends 1a, 2a and the wall members 4a, 4b so as to be freely rotatable around the longitudinal direction of the vehicle ends 1a, 2a. As the connection structure that allows the rotation of the elastic members 6a and 6b or the wall members 4a and 4b, the elastic members 6a and 6b and the wall members 4a and 4b are integrally formed, and both are connected by a hinge structure, Although a method using deformation of the material itself can be considered, these do not limit the contents of the present invention.

  According to this inner wall structure of the passage, the plurality of wall members 4, 4a, 4b, 5, 5a, 5b juxtaposed in the direction of passage of the passage and the connecting members 8a, 8b, 9a disposed between the adjacent wall members. , 9b, the wall member made of an elastic material even if various forms of relative changes occur between the vehicle ends 1a, 2a of the adjacent vehicles 1, 2 depending on the rails for running the vehicle. By deforming the connecting members 8a, 8b, 9a, 9b made of 4, 4a, 4b, 5, 5a, 5b and the elastic material, the inner wall structure is maintained by absorbing the relative displacement. Further, the elastic members 6a, 6b, 7a connected between the wall members 4a, 4b, 5a, 5b and the vehicle ends 1a, 2a so as to be freely rotatable around the longitudinal direction of the vehicle ends 1a, 2a. , 7b, the deformation can be started immediately following the relative displacement between the vehicle ends 1a, 2a from the elastic members 6a, 6b, 7a, 7b, and the entire inner wall structure Share the deformation. Therefore, even when the vehicle passes through a curved road having a small R, this inner wall structure can cope with a movement in which the distance between the vehicle ends greatly expands and contracts inside and outside the curve.

  FIG. 5 shows an enlarged cross-sectional view of the passage inner wall structure shown in FIG. The central main wall member 4 is an elliptical cylindrical body that is larger and flatter in cross section than the sub-wall members 4a and 4b on both sides disposed on the vehicle side. Each of the connection members 8a and 8b uses a single elastic plate formed as a plate as an elastic material, and the elastic plate is formed by folding it in the middle. As for connection member 8a, 8b, each side edge part of a board is connected with the mutual adjacent edge part of wall member 4, 4a, 4b to which it respectively respond | corresponds. Specifically, the connecting members 8a and 8b are elliptical long edge portions 31 and 32 in the cross section of the wall member 4, and long elliptical edge edges in the cross section of the wall members 4a and 4b. The parts 33 and 35 are connected. Most of the main bodies of the connecting members 8a and 8b are located behind the wall members 4, 4a and 4b when viewed from the through-passage space and do not touch the passengers' eyes. Therefore, with such an inner wall structure, passengers who travel through the through-passage do not see the hood 3 on the outside, but only the upgraded wall members 4, 4a, 4b. Become. The wall members 4a and 4b are attached to the end portions 37 and 38 of the elastic members 6a and 6b attached to the vehicle end 1a and the vehicle end 2a, respectively, at the edge portions 34 and 36 in the major axis direction having an elliptical cross section. ing.

  The connecting members 8a and 8b are integrally formed of a long elastic material in which the short side is folded in half, and the front end portions 39 and 40 on the long side of the connecting member 8a are respectively connected to the wall members 4 and 4, respectively. In addition, the long side end portions 41 and 42 of the connection member 8b are attached to the wall members 4 and 4b using an adhesive or the like. The connection members 8a and 8b are elastically deformed by themselves, and in particular, the end portions 39, 40 and 41, 42 are opened around the folded portions 43, 44, so that the wall members 4, 4a, 4b Responds to changes in spacing.

  The connection members 8a and 8b are preferably arranged along the wall members 4, 4a and 4b on the rear side of the wall members 4, 4a and 4b. By arranging in this way, the wall thickness of the inner wall structure can be reduced, and the through-passage portion can be secured widely in the width direction.

  FIG. 6 is an enlarged cross-sectional view showing another example of the passage inner wall structure according to the present invention. In FIG. 6, only the connection part of the wall members 4 and 4a is shown. In the inner wall structure shown in FIG. 6, the wall members 4 and 4a are partially embedded with, for example, metal coupling core members 60 and 61 in the end edge portions 31 and 33 that are the connecting portions with the connection members 50a. It is molded in a state and configured integrally. The connecting core members 60 and 61 are fixed arm portions 62 and 63 extending from the edge portions 31 and 33 along the inner surface of the wall member 4 and 4a made of a cylindrical body, and from the center of the fixed arm portions 62 and 63. And a connecting arm portion 64 that extends through the end edge portions 31 and 33 so as to protrude to the back surface side that is the connection member 50a side of the inner wall structure. The elastic material constituting the wall members 4 and 4a extends outside the connecting arm portion 64 to prevent direct contact between the connecting arm portions 64 and 64 when the wall members 4 and 4a approach and collide with each other. It has a buffering effect. The connection member 50 a is coupled to the coupling arm portion 64. By using the coupling core members 60 and 61, the connection member 50a can be easily and reliably coupled to the wall members 4 and 4a.

  In the example shown in FIG. 6, the connection member 50 a is composed of two elastic plate members 51 and 52. The elastic plate members 51 and 52 are coupled by a fixing means such as a rivet 54 in a state where the edge portions 51 a and 52 a on the long side that are overlapped are sandwiched by the metal fitting 53. The edge portions 51b, 52b on the front side of the inner wall structure of the elastic plate members 51, 52, that is, the other long side, are rivets 55, 55 with respect to the connecting arm portions 64, 64 of the connecting core members 60, 61, respectively. It is fixed. The connecting member 50a is elastically deformed by the elastic plate members 51 and 52 itself. In particular, the connecting member 50a is elastically deformed with bending using the edge portions 51a and 52a on one long side as a fulcrum. The opening degree of the opening 56 formed between the side edge portions 51b and 52b is configured to be variable, and can cope with a change in the interval between the wall members 4 and 4a. Although not shown, the same structure (connection member 50b, not shown) as shown in FIG. 6 is adopted between the wall members 4 and 4b. In this example, the two elastic plate members 51 and 52 are overlapped. However, the elastic plate members 51 and 52 are not folded in two, but may be referred to as folded in two.

  2 is a longitudinal sectional view of the inner wall structure of the passage shown in FIG. In this figure, the crossover plate 12 of the through-passage portion is indicated by a one-dotted line, but the shape of the crossover plate is not directly related to the present invention and does not affect the inner wall structure of the through-passage portion. In this figure, when adjacent vehicles cause relative rolling motion, twist deformation occurs between the vehicle 1 and the vehicle 2 around the longitudinal direction of the vehicle. This deformation is a deformation of the aspect in which the connecting members 8a and 8b provided between the wall members 4 and 4a and the wall members 4 and 4b are displaced in the vehicle width direction at the openings 45 and 46 (see FIG. 5) Depending on). That is, when a shearing force with torsional deformation is applied between the wall member 4 and the wall member 4a or 4b, the connecting member 8a or 8b is twisted and deformed while following the wall member 4 and the wall member 4a or 4b. do. As a result, the connecting members 8a and 8b can absorb the displacement due to rolling of the vehicle body. In this case, the gap between the wall members 4a and 4b and the wall member 4 does not open widely, and the connecting members 8a and 8b can also cover the top. As a result, the appearance of the inner wall does not deteriorate.

  In addition, the constituent members of these inner walls have a smaller number of members and almost no mechanism structure compared to the conventional inner wall structure, particularly the structure described in Patent Document 2, so that the overall construction weight is simplified. Can be made lighter and lighter, and the installation man-hours and work can be reduced.

  Furthermore, when the vehicle 1 and the vehicle 2 cause a relative pitching motion, similarly, the deformation of the connecting members 8a and 8b is, for example, at the opening portions 45 and 46 (see FIG. 5). Absorption is caused by deformation of the aspect deviating in the direction (the amount of deviation varies depending on the position).

  FIG. 3 is a diagram illustrating a state of the through-passage portion when the vehicle 1 and the vehicle 2 pass a single curve. The upper side of the figure shows the outside of the curve, and the lower side shows the inside of the curve. From the figure, the distance between the vehicle end 1a and the vehicle end 2a is shortened inside the curve, so that a compressive force acts on the entire inner wall. When a compressive force is applied, the wall member 5 is a cylindrical body having an elastic structure, and thus deforms so that the thickness increases toward the inside and outside of the vehicle. At this time, the wall member 5 is greatly convex toward the passage. That is, when relative displacement occurs in the direction in which the distance between the vehicle ends 1a and 2a is reduced, the adjacent wall members 5, 5a and 5b are subjected to compressive displacement generated in the passage direction of the through-passage portion in the contact state. , 5a, 5b themselves absorb the relative displacement by deformation that swells in the passage width direction of the through passage.

  On the other hand, a tensile force acts on the entire inner wall outside the curve. Since the wall members 4, 4 a, 4 b are cylindrical bodies configured in an elastic structure, the wall members 4, 4 a, 4 b are deformed so that the thickness decreases toward the inside and outside of the vehicle. That is, the tensile displacement generated in the passage direction of the through-passage portion is absorbed by deformation in the direction in which the wall members 4, 4a, 4b are flattened. When a larger tensile force is applied, the wall members 4 and 4a and the connecting members 8a and 8b between the wall members 4 and 4b are deformed so as to slightly open in the folded openings 45 and 46 (see FIG. 5). To absorb the displacement. However, even if it becomes such a state, since the wall members 4, 4a, 4b are connected by the connecting members 8a, 8b, the hood 3 cannot be seen. Therefore, a comfortable space where only the inner wall structure can be seen from the vehicle interior side can be provided.

  FIG. 4 shows a through-passage state when the vehicle 1 and the vehicle 2 pass through an S-shaped opposing curve. When passing through the midpoint of the opposing curve, the distance between the vehicle body 1 and the vehicle body 2 is slightly reduced in the vehicle longitudinal direction and greatly deviated in the vehicle width direction. In this state, a tensile force acts on the entire inner wall, so that the deformed state is almost the same as that of the outer inner wall in FIG.

  FIG. 7 shows another embodiment of the present invention. In this embodiment, decorative wall members 20 and 21 for creating a higher quality space are attached to the surface of the wall members 4 and 5 on the passage side. The decorative wall members 20 and 21 are attached to the wall members 4 and 5 via decorative wall holding members 22a and 22b and 23a and 23b, respectively. The decorative wall holding members 22a, 22b, 23a, and 23b are made of a material and a structure that are deformed integrally with the movement of the surface layer of the wall members 4 and 5. Furthermore, the decorative wall members 20 and 21 are configured to be interlocked with decorative wall holding members 22a, 22b, 23a, and 23b that transmit the movement of the surface layer of the wall members 4 and 5. The width of the decorative wall members 20 and 21 is set to a width that covers the entire width portion of the space between the vehicle ends 1a and 2a when the vehicle is on a normal straight track. Therefore, the wall members 4, 4a, 4b, 5, 5a, 5b and the connecting members 8a, 8b, 9a, 9b between the vehicle ends 1a, 2a are in a position hidden from the passage side, and passengers come and go through the through passage. Substantially sees only the decorative wall members 20, 21, and the interior of the through-passage portion can be further refined. The decorative wall members 20, 21 and the wall members 4, 5 are connected by holding members 22a, 22b, 23a, 23b. This connection is made by an adhesive or pin connection. In the case of pin connection, the pins are fixed to the decorative wall members 20 and 21, and the decorative wall holding members 22 a, 22 b, 23 a, and 23 b are fixed to the wall members 4 and 5. In this state, the decorative wall members 20, 21 are lowered from above, and a plurality of pins are inserted into the holes of the holding members 22a, 22b, 23a, 23b.

  In the present embodiment, the decorative wall members 20 and 21 are arc-shaped covers in which the central portion in the passage direction of the passage projects from the both end portions toward the passage side. In this case, a smooth and uncomfortable structure can be obtained as the structure of the through passage portion. The decorative wall members 20 and 21 have a structure in which the central portion is deformed in a convex shape toward the passage side as the wall members 4 and 5 are deformed in a convex shape by the compressive force applied to the wall members 4 and 5. Since the decorative wall members 20 and 21 are deformed together with the deformation of the wall members 4 and 5, interference between the decorative wall members 20 and 21 and the wall members 4 and 5 can be prevented.

  Next, the state when passing through a single curve is shown in FIG. The upper side of FIG. 8 is the outside of the curve, and a tensile force acts on the members constituting the through path. Each member operates in the same manner as described with reference to FIG. 3, but the state in which the connecting members 8a and 8b are slightly opened can be hidden by the decorative wall member 20 and the decorative wall holding members 22a and 22b. Is further improved. Further, on the side on which the compressive force on the inner side of the curve acts, each member operates in the same manner as described in FIG. At that time, the inner wall member 5 is deformed in a convex shape toward the penetrating path, but the decorative wall holding members 23a and 23b attached to both sides of the wall member 5 are narrowed toward the center of the wall member 5. Displace. Accordingly, the decorative wall member 21 connected to the decorative wall holding members 23a and 23b is also deformed so that both sides are narrowed with the central portion convex. For this reason, since the joint part of wall member 5,5a, 5b and connection member 9a, 9b is concealed by the decorative wall member 21, the inner wall of a through-passage part is kept good-looking. Further, if the decorative wall members 20 and 21 are formed so that both ends of the wall form a closed arc, the inner wall of the through-passage is kept more attractive.

  In addition, the constituent members of these inner side walls have a smaller number of members than the structure described in Patent Document 2 and there are almost no mechanical structures, so that the overall configuration weight can be reduced, and the number of installation work steps and work can be reduced. Can be reduced. There are advantages.

  FIG. 9 shows another example of the inner wall structure according to the present invention. The inner wall structure shown in FIG. 9 includes two wall members 70a and 70b having the same size as wall members juxtaposed in the direction of passage of the passage, and a connection member 71 between the two wall members 70a and 70b. Is arranged. The wall members 70a and 70b are arranged in a line between the elastic members 6a and 6b attached to the adjacent vehicle ends 1a and 2a, respectively. The connection member 71 that connects the wall members 70a and 70b is provided on the back side of the inner wall structure. The wall members 70a and 70b correspond to the wall members 4, 4a and 4b of the above-described embodiment, and are formed of a cylindrical body made of an elastic body. The wall members 70a and 70b are directly attached to the elastic members 6a and 6b at the outer edge portions 72 and 73, respectively. The connection member 71 is made of an elastically deformable material, and is attached to the edge portions 74 and 75 of the wall members 70a and 70b. The connecting member 71 has a shape in which two curved elastic plate members 76 and 77 are stacked so as to have a bulge, and end portions 78 and 79 on one long side are end edges of the wall members 70a and 70b. It is connected to the parts 74 and 75. The end portions 80 and 81 on the other long side of the plate members 76 and 77 constituting the connecting member 71 are fixed in a state of being sandwiched by the metal fittings 82. The connecting member 71 absorbs the relative displacement of the wall members 70a and 70b, and conceals the gap between the wall members 70a and 70b from the eyes of the passenger passing through the through passage, thereby contributing to the quality improvement of the inner wall structure.

  As described above, the present invention has been described as an inner wall structure of a through passage portion provided between adjacent vehicles configured in a knitting in which a plurality of vehicles are connected. Applicable to vehicles. In this case, it is effective to improve the habitability of the through-passage part constituting the formation of the rail vehicle. Further, it is obvious that the present invention can be applied not only to the inner wall structure of a through-passage portion in a rail vehicle such as a railway vehicle, but also to a connecting portion of a bus having a connecting portion or a transportation lap to a ship or an airplane. is there.
