In the door structure, base ends of a pair of laterally arranged frames are rotatably connected to both-side lower end portions in the opening portion, the frames are foldable at a generally middle position in a longitudinal direction via a hinge such that the frames are inwardly folded over each other, a plurality of footboard members each having a constant width are continuously arranged between and along the frames to constitute a footboard face in the state where the frames are straightly extended. In the state where the frames are folded in two, the individual footboard members are moved to the side with the hinge portion, and stacked. Since the stacking position of the footboard members is located in a housing portion above the window of the door, and does not interfere with the window, in the state where the lower end of the door is rotated to the lower end portion in the opening portion and the opening portion is closed by the door, the scenery outside the vehicle can be seen through the window of the door. -

European Patent Application No.0776808 - However, also in the foregoing door structure described in
Patent Document 3, there are the following problems to be solved. - The door that is swung forwardly and upwardly to be opened and the slope with a pair of frames that constitute the footboard face in case of emergency escape and are folded in two via the hinge are constituted as individual independent units, and hence the structure is complicated.
- In the state where the door is swung forwardly and upwardly to be opened, the slope that is folded in two is positioned in the opening portion in its upright state so that smooth escape in emergency may be hindered.
- In the state where the door is opened, since the door extends in an almost horizontal and forward direction upwardly of the front of the vehicle, in a mode where two vehicles are closely faced each other, and a transfer is performed from one vehicle to the other vehicle, the doors that are swung forwardly and upwardly to be opened may interfere with each other.
- In the event of emergency escape, it is necessary to perform two actions (operations) in which the door is swung forwardly and upwardly to be opened, and the folded frames are extended straight to continuously spread the footboard members to form the footboard face.

US 4,216,725 forms the basis for the preamble ofclaim 1 and discloses a combination door and emergency stairway exit. - From
ES-A1-2 133 093 - The present invention has been achieved in view of the foregoing, and the present invention provides a door structure for a railway vehicle that is usable as a doorway in case of an emergency, and is capable of smoothly forming a slope for escape in a door with a window.
- To achieve the foregoing object, a door structure for a railway vehicle according to the present invention is configured as recited in
claim 1. - According to the door structure for a railway vehicle of the present invention having the above-described configuration, since the door is constituted by integrating the door main body, the door frame, and the extension footboard portion together, the structure is simplified as compared with the prior art technique having the window in the door and, since a slope portion for escape is opened as the door together with the door when the door is opened, the slope portion for escape does not get in the way. In addition, since the door is opened in a forward and a lateral direction in the tip end face of the vehicle, the doors of two vehicles do not interfere with each other in a state where the tip ends of the two vehicles are closely faced each other and, consequently, it is possible to dispose a relatively short gangway footplate to bridge between the vehicles to transfer passengers between the vehicles, as illustrated in
FIGS. 13 and14 . Further, the window of the door main body and the opening portion for window of the extension footboard portion are cleared in the close state of the door (a normal state, and a state where the door main body closes the opening portion) and, in the forward full open state of the door (an emergency escape state and a state where the door main body is opened forward using the lower end portion of the door frame serves as the axis, and the folded extension footboard portion is opened forwardly of the opened door main body), the first footboard portion covers the window and the second footboard portion covers the opening for window (by a link mechanism and the action of gravity in an embodiment) to constitute a footboard for escape (slope) so that it is possible to smoothly escape irrespective of the presence or absence of the window. - As has been described thus far, the door structure for a railway vehicle of the present invention is usable as a doorway in case of an emergency, and is capable of smoothly forming a slope for escape in a door with a window.

FIG. 1 , in an end panel (front surface) 2 of a tip of a body of a front vehicle (inclusive of the last vehicle) 1, a verticallylong opening portion 3 is provided in a central portion thereof, and anopening frame 4 is fitted in theopening portion 3. To theopening frame 4, a door (hinged door) 5 is attached using a hinge 6 (seeFIG. 5 ) so as to be openable in a forward and a lateral direction (when viewed from the inside of thevehicle 1, from a forward direction to a lateral direction (a left-side direction or right-side direction)). Thedoor 5 has a window 5c in its upper portion and includes a door main body (sloped door) 7 and a door frame 5a in its circumferential edge portion so as to be detachable from each other, and a lower end of the doormain body 7 is connected to a lower end edge 5b of the door frame 5a via the hinge or aspindle 9 so as to be openable such that the doormain body 7 is tilted forward and downward. In a state where the doormain body 7 is integrated with the door frame 5a and anextension footboard portion 8 described later, the doormain body 7 is opened and closed about an axis of thehinge 6 as the door (hinged door) 5. Specifically, as illustrated inFIG. 3 , in the state where the doormain body 7 is integrated with the door frame 5a and theextension footboard portion 8, the doormain body 7 is rotated in the forward and a lateral direction with respect to theopening frame 4 via thehinge 6 to open theopening portion 3. In addition, guide rollers 5d are attached to both sides of a lower end face of the door frame 5a and, in a state where thedoor 5 is returned to the original position together with the door frame 5a via thehinge 6 to close theopening portion 3, the guide rollers 5d come in contact with an under face in theopening frame 4 to support theentire door 5. As illustrated inFIG. 7 , afootboard cover 53 is attached to extend from a walkway of thefront vehicle 1 to the lower end portion of the doormain body 7 so as to cover thespindle 9. - On a back face side (vehicle interior side) of the door
main body 7 as the door on the first tier, theextension footboard portion 8, which constitutes, in an emergency escape state, a footboard face (escape step) together with a face of the doormain body 7 on the vehicle interior side, is provided to be connected to the doormain body 7 so as to be foldable about thespindle 10. Specifically, theextension footboard portion 8 is slightly narrower in width and slightly shorter in length than the doormain body 7, and one end (base end) of theextension footboard portion 8 is connected to the upper end of the doormain body 7 via the hinge or thespindle 10 so as to be rotatable about the axis by approximately 180°. The doormain body 7 is provided with the window 5c at a position slightly above the middle position in a longitudinal (vertical) direction. The window 5c has a transparent glass pane 11a. - As illustrated in
FIG. 7 , the surface of the doormain body 7 has a longitudinal section that is curved forward (downward) and convexly in an arc shape over its length. On the face of the doormain body 7 on the vehicle interior side, the portion below the window 5c is protruded backward (upward) from the lower end thereof toward a slightly upward portion, and both-side frame walls 11b are formed on both-side edge portions 7a from the end of the protruded portion toward the upper end of the doormain body 7 in such a manner as to cross the upper end. In addition, afootboard face 12 is formed to bridge between the both-side frame walls 11b so as to cover a space portion. Thefootboard face 12 is comprised of a portion 12b that covers the window 5c (hereinbelow referred to as a first footboard portion), and a lower portion 12a. In this embodiment, the first footboard portion 12b is attached between guide frames 11c that are provided to protrude on the both-side frame walls 11b so as to be slidable on the lower portion 12a and the window 5c. When the doormain body 7 is raised, the first footboard portion 12b descends by its own weight to lie on top of the lower portion 12a in a state where the first footboard portion 12b is integrally fitted in the the door frame 5a. In other words, the window 5c is opened. In a state where the doormain body 7 is rotated about thespindle 9 forward and downward by about 100° to 110° with respect to the door frame 5a to be tilted forward, the first footboard portion 12b moves to a position over the window 5c by its own weight along and between the guide frames 11c to cover the window 5c. It is to be noted that an anti-slip sheet is affixed on the footboard face 12 (surface). - By the way, the first footboard portion 12b is slidable on the lower portion 12a and the window 5c along the guide frames 11c. In the state where the door
main body 7 is rotated about thespindle 9 forward and downward to be tilted forward, the first footboard portion 12b moves to the position over the window 5c by its own weight to cover the window 5c, as described above. On the other hand, in the state where the doormain body 7 is raised, and integrally fitted in the door frame 5a, the first footboard portion 12b lies on top of the lower portion 12a by its own weight, and the window 5c is opened. Accordingly, In the present embodiment, there is provided alashing mechanism 60 for fixing a portion that covers the window when the first footboard portion 12b has moved to the position over the window 5c. - A description will be given hereinbelow of an embodiment of the
lashing mechanism 60 on the basis ofFIGS. 17 to 21 .FIGS. 17 to 20 are explanatory views for sequentially explaining opened states of the doormain body 7 and theextension footboard portion 8, and operational modes of thelashing mechanism 60 from a closed state to the opened state, in which FIGS. (a) are right-side cross-sectional views of the doormain body 7 and theextension footboard portion 8, FIGS. (b) are plan views thereof, and FIGS. (c) are explanatory views of the operational modes of the lashing mechanism.FIG. 21 includes a plan view and a side view each illustrating the entire lashing mechanism,FIG. 22 includes a plan view, a cross-sectional view taken along the line A-A, and a cross-sectional view taken along the line B-B each illustrating a door-side stopper, andFIG. 23 includes a plan view and a cross-sectional view taken along the line A-A each illustrating a window cover-side stopper. - As illustrated in
FIG. 21 , thelashing mechanism 60 is constituted of a combination of the door-side stopper 61 and the window cover-side stopper 71. As illustrated inFIG. 22 , the door-side stopper 61 is provided in the doormain body 7. On the other hand, as illustrated inFIG. 23 , the window cover-side stopper 71 is provided in the first footboard portion 12b. - In the door-side stopper 61, a generally L-shaped
stopper member 63 is openably and closably connected onto anattachment frame 62 so as to be rotatable using aspindle 64. Thestopper member 63 is biased in an opening direction using ashaft 65 via aspring 66. Alatch 67 is disposed on an upper end of theshaft 65 to be upwardly protruded from an upper end of theattachment frame 62, and a lower end face of thelatch 67 is coupled to an upper end face of theshaft 65. The window cover-side stopper 71 has a long generally I-shapedstopper member 73 on anattachment frame 72 smaller than theattachment frame 62, and a nail portion 73a that is engageable with and detachable from a nail portion 63a of thestopper member 63 at its tip, and a lower end portion of thestopper member 73 is connected using aspindle 74 so as to be laterally rotatable. An upper portion of thestopper member 73 is protruded upwardly of theattachment frame 72, and is biased in an engaging direction with respect to thestopper member 63 using aspring 75. Thespring 75 is guided by twoguide members 76. - As illustrated in
FIG. 21 , the door-side stopper 61 is attached to the doormain body 7 using four bolts (and nuts) 68 such that its vertical position is adjustable. The window cover-side stopper 71 is attached to the first footboard portion 12b using four bolts 77 such that its vertical position is adjustable. With this configuration, by adjusting the respective vertical positions, the window cover-side stopper 71 is reliably engaged with the door-side stopper 61. As illustrated inFIGS. 21 to 23 , in the vicinity of thespindle 64 of thestopper member 63 of the door-side stopper 61, aprotrusion portion 69 is provided to protrude in a direction opposite to that of the nail portion 63a. In addition, locking members 65b and 65c are integrally formed at positions above and below the middle portion of theshaft 65. A configuration is adopted in which, by moving theshaft 65 vertically, the locking member 65a or 65c is engaged with theprotrusion portion 69, and thestopper member 63 is thereby rotated clockwise or anticlockwise about thespindle 64. - Herein, a description will be given of the opened states of the door
main body 7 and theextension footboard portion 8, and the operational modes of thelashing mechanism 60 sequentially from the close state of thedoor 5 to the forward full open state of the door. - In
FIGS. 17 to 20 , - 1) In a state where the
door 5 is closed, the window 5c of the doormain body 7 and an open portion forwindow 13 of theextension footboard portion 8 are opened, the first footboard portion 12b of the doormain body 7 lies on top of the lower portion 12a, and the door-side stopper 61 and the window cover-side stopper 71 are spaced apart from each other (FIG. 17 ). - 2) In a state where the door
main body 7 as the first tier of thedoor 5 is tilted forward and downward, theextension footboard portion 8 as the second tier is in an upright state at the tip end of the doormain body 7. At this time, the first footboard portion 12b moves to the position over the window 5c by its own weight along and between the guide frames 11c to cover the window 5c. In this state, the window cover-side stopper 71 moves toward the tip end side relative to the door-side stopper 61, and they are brought into an engageable state (FIG. 18 ). - 3) With respect to the door
main body 7, theextension footboard portion 8 as the second tier is opened in an extending direction of the doormain body 7, thelatch 67 of the door-side stopper 62 is thereby pressed against thespring 66, and thestopper member 63 is rotated clockwise to be brought into engagement with the window cover-side stopper 71. In addition, as will be described later, the opening portion forwindow 13 on the side with theextension footboard portion 8 is also covered with the second footboard portion 14b vialinks 15 in synchronization with the opening operation (FIG. 19 ). - 4) In the state illustrated in
FIG. 19 , even if the first footboard portion 12b is to move toward the rear portion side, since thestopper member 73 of the window cover-side stopper 71 is biased by thespring 75 in the engaging direction, the engagement with thestopper member 63 of the door-side stopper 61 is maintained, and the first footboard portion 12b does not move (FIG. 20 ). - The
extension footboard portion 8 is provided with the opening portion forwindow 13 at a position matching that of the window 5c of the doormain body 7 in a state where theextension footboard portion 8 is not rotated in the close state of the door (normal state) (in other words, a state where theextension footboard portion 8 is folded to be stacked on the vehicle interior side of the door main body 7). On the surface of theextension footboard portion 8, U-shaped frames 13b and 13c are provided to protrude in upper and lower portions of the opening portion forwindow 13, and the U-shaped frames 13b and 13c are utilized when theextension footboard portion 8 is returned from the rotated state to the normal state. In addition, on the face of theextension footboard portion 8 on the vehicle interior side (face directed upward in the rotated state), afootboard face 14 is formed, and thefootboard face 14 is comprised of a lower portion 14a of the opening portion forwindow 13, and the second footboard portion 14b. The lower portion 14a is fixed to the position of the lower portion of the face of theextension footboard portion 8 on the vehicle interior side, but the second footboard portion 14b is provided so as to be slidable between positions on the lower portion 14a and the opening portion forwindow 13 along and between a pair of laterally arranged guide frames 13a and 13a. Further, to both-side upper end portions of the the second footboard portion 14b, one end portions of thelinks 15 are rotatably connected using pivoting pins 15d via brackets 15c, and the other end portions of thelinks 15 are rotatably connected to positions close to the upper end on both sides of the doormain body 7 using pivoting pins 15b via brackets 15a. - With this configuration, when the
extension footboard portion 8 is rotated upward and forward by approximately 180° from the state where theextension footboard portion 8 is folded to be stacked on the vehicle interior side of the doormain body 7, the second footboard portion 14b moves to the position on the opening portion forwindow 13 from the position on the lower portion 14a in such a manner as to be pulled by the thelinks window 13. Reversely, when theextension footboard portion 8 is laid on top of the face of the doormain body 7 on the vehicle interior side while being folded to be retuned to its original state from the rotated state, the second footboard portion 14b moves to the position on the lower portion 14a in such a manner as to be pushed up by thelinks window 13, and opens the opening portion forwindow 13. On the footboard face 14 (surface), the anti-slip sheet is affixed. - As illustrated in
FIGS. 7 and8 ,brackets 18 are uprightly fixed in the vicinities of respective upper end portions of the both-side edge portions 7a of the doormain body 7, and one end portions of supportinglinks 17 are fixed to thebrackets 18 using pivoting pins 17a disposed in a lateral direction orthogonal to the side faces of the supportinglinks 17 so as to be rotatable about the axes of the pivoting pins 17a. The other ends of the supportinglinks 17 are connected to the upper end portions in the door frame 5a viatraction chains 19. At this time, upper ends of thetraction chains 19 are fixed to the upper end portions in the door frame 5a or ceiling portions in thefront vehicle 1. In addition, at generally middle positions in a longitudinal direction (vertical direction) on the both-side edge portions 7a of the doormain body 7, one end portions ofauxiliary links 21 are fixed using pivoting pins 21a disposed in the lateral direction orthogonal to side faces of theauxiliary links 21 viabrackets 22 so as to be rotatable about the axes of the pivoting pins 21a. Further, the other ends of theauxiliary links 21 are fixed at generally middle positions in the longitudinal direction of the supportinglinks 17 using pivoting pins 17b disposed in the lateral direction orthogonal thereto so as to be rotatable about the axes thereof, and elongated holes 21c are formed to be slidable relative to the pivoting pins 17b over a predetermined length in the longitudinal direction from the other ends of theauxiliary links 21. It is to be noted that elongated grooves or groove-like sliders may be used instead of the elongated holes 21c. - A configuration is adopted in which, in the upright state of the door main body 7 (state where the door
main body 7 is integrally fitted in the door frame 5a), the corresponding support links 17 andauxiliary links 21 are disposed in parallel with each other to be laid on top of each other. In addition, one ends of L-shapedbrackets 20 are fixed to be laterally protruded at portions close to the tip end portions on both sides of theextension footboard portion 8. To upright portions of the L-shapedbrackets 20, one end portions of second supportinglinks 23 are fixed using pivoting pins 20a disposed in the lateral direction orthogonal to side faces of the upright portions so as to be rotatable about the axes thereof. Further, the other ends of the second supportinglinks 23 are connected to the other end portions of the supportinglinks 17 viasecond traction chains 24. Furthermore,handrail chains 25 are disposed to bridge between positions in the vicinities of the lower end portions of thetraction chains 19 and positions slightly below the middle positions in the vertical direction in the door frame 5a. - As illustrated in
FIGS. 4 and5 , to a position close to the upper end portion in theopening frame 4 of therailway vehicle 1, one end of a closingoperation traction chain 26 for the doormain body 7 is fixed. As illustrated inFIG. 7 , at the middle position in the longitudinal direction of the upper end of one side wall of the doormain body 7 and one side face of theextension footboard portion 8, aroller 28 is disposed to be laterally protruded. The other end side of the closingoperation traction chain 26 is fixed to aneyebolt 27, and is connected to a closing operation tractionchain winding apparatus 32 attached to the right side in the ceiling portion in the railway vehicle so as to be wound by way of theroller 28, a chain windingshock absorption apparatus 29, and twopulleys 30 and 31 that are attached to the left side of the ceiling portion thereof. Theshock absorption apparatus 29 has a control apparatus therein that keeps a paying out speed of thetraction chain 26 under a predetermined value by spring force and friction, and as theshock absorption apparatus 29, for example, a speed governor of a slowdown elevator (SLOWDOWN 125 (registered trademark)) of kabushiki kaisha shoubou kagaku kenkyujo can be used. As illustrated inFIGS. 4 and5 , in the tractionchain winding apparatus 32, an upper end engagement portion 33a of arotation operation member 33 is engaged with an engagement portion 32a of the tractionchain winding apparatus 32, and therotation operation member 33 is manually rotated to wind the opening/closingoperation traction chain 26. As a result, theextension footboard portion 8 in the rotated state is firstly folded about thespindle 10, and then laid on top of the face of the doormain body 7 on the vehicle interior side in the rear. In this state, by continuing the winding operation of the closingoperation traction chain 26, the doormain body 7 is rotated backward and upward to be fitted in the door frame 5a, and they are integrated together. - In this state, as illustrated in
FIG. 4 , locking nails 42 of locking mechanisms 41 provided at middle positions in the vertical direction of the door frame 5a on both sides of the doormain body 7 are engaged with locking grooves 44a of locks 44 (seeFIGS. 10 and11 ) provided in upper and lower portions on both sides of the doormain body 7 by biasing force of springs (not shown), and the doormain body 7 is thereby integrated with the door frame 5a. On the other hand, when the integration of the doormain body 7 and the door frame 5a is disintegrated in order to set the emergency escape state, inFIGS. 6(a) to 6(c) , lock release levers 43 provided at the middle positions on both sides of the door frame 5a are rotated toward an outward (the door frame 5a) side as illustrated inFIG. 6(b) , whereby the locking nails 42 engaged with the locking grooves 44a (seeFIG. 10 ) of the doormain body 7 are pulled in toward the side with the door frame 5a against the springs as illustrated inFIG. 6(a) , and the locked state is released as illustrated inFIG. 6(c) . - In addition, locking mechanisms 45 of the
door 5 are provided on upper and lower portions on both sides of the door frame 5a, as indicated by areference numeral 48 inFIGS. 6(d) and 6(e) . As illustrated inFIG. 6(e) , by rotating locking operation handles 46 from downward locking positions to horizontal positions on the side with the doormain body 7, locking nails 47 fitted in locking grooves (not shown) in theopening frame 4 move out of the door frame 5a as illustrated inFIG. 6(d) , and the locked state is thereby released. Herein, when one side portion (side opposite to the hinge 6) of thedoor 5 is pushed forward, thedoor 5 is rotated via thehinge 6 about its axis together with the door frame 5a relative to theopening frame 4, and theopening portion 3 is thereby opened. It is to be noted that the locking mechanisms 45 are disposed in storage portions of the door frame 5a, and the individual storage portions are normally closed with open/close lids 48. - Next,
FIGS. 13 and14 illustrate another mode in the emergency escape state in which passengers are allowed to move to another vehicle without getting off a vehicle to be on a railway track. Specifically, the openingportions 3 of the tip end faces 2 of thefront vehicles 1 and 1' are brought close together to be faced each other in a state where thedoors 5 are fully opened in a forward and a lateral direction, thegangway footplate 52 is disposed to bridge between the footboard covers 53 of the tipend opening portions 3 of thefront vehicles 1 and 1', andhandrail chains 54 are connected between the middle positions of the opening frames 4 and 4'. As a result, passengers on onevehicle 1 are allowed to move to the other vehicle 1' across thegangway footplate 52. - In view of the foregoing, according to the present invention, it is possible to achieve the following effects.
- The
door 5 structure for the railway vehicle provided in theopening portion 3 in theend panel 2 of the railway vehicle is characterized by including the door frame 5a having thehinge 6 on one side portion, the doormain body 7 that is pivotally openable and closable in a lateral direction of the railway vehicle while thehinge 6 serves as the axis, pivotally openable and closable in a forward direction of the railway vehicle while the lower end portion 5b of the door frame 5a serves as the axis, and provided with the window 5c and the first footboard portion 12b covering the window 5c in the forward full open state of the door, and theextension footboard portion 8 that is folded to be storable on the vehicle interior side of the doormain body 7 in the close state of a door, and provided with the opening portion forwindow 13 positioned on the vehicle interior side of the window 5c in the close state of a door, and the second footboard portion 14b covering the opening portion forwindow 13 in the forward full open state of a door. - According to the door structure for the railway vehicle of the present invention having the above-described configuration, since the
door 5 is constituted by integrating the doormain body 7, the door frame 5a, and theextension footboard portion 8 together, the structure thereof is simplified as compared with that the prior art technique having the window in the door and, when the door is opened, the slope portion for escape is also opened together as the door so that the slope portion for escape does not get in the way. In addition, since the doormain body 7 is openable in the forward and a lateral direction, the doors of two vehicles do not interfere with each other in the state where the tip ends of the two vehicles are closely faced each other and, accordingly, it is possible to dispose the relatively short gangway footplate to bridge between the vehicles to transfer passengers between the vehicles, as illustrated inFIGS. 13 and14 . Further, since the window 5c of the doormain body 7 and the opening portion forwindow 13 of theextension footboard portion 8 are opened in the close state of the door, and the window 5c and the opening portion forwindow 13 are covered with the first footboard portion 12b and the second footboard portion 14b, respectively, to constitute the footboard face (slope) for escape in the forward full open state of the door, it is possible to smoothly escape irrespective of the presence or absence of the window. - Specifically, the door structure having the above-described configuration has the following excellent effects.
- • Since the structure is simplified as compared with the conventional door structure having the window in the door and, when the door is opened, the slope portion for escape is opened together with the door, the slope portion for escape is less likely to get in the way.
- • Since the door is opened in the forward and a lateral direction of the tip end face of the vehicle, in the state where the tip ends of two vehicles are closely faced each other, the doors of both of the vehicles do not interfere with each other, and it is possible to dispose the relatively short gangway footplate to bridge between the vehicles to transfer passengers from one vehicle to the other.
- • In the normal state, the window of the door main body and the opening portion for window of the extension footboard portion are completely opened so that it is possible to see the scenery outside the vehicle and the like. On the other hand, in the emergency escape state, since the window is covered with the first footboard portion and the opening portion for window is covered with the second footboard portion to constitute the walkway for escape, it is possible to smoothly escape irrespective of the presence or absence of the window and the opening portion for window.
- • It is possible to use the opening portion that is the doorway for normal use as the doorway for emergency use, and smoothly form the slope for escape manually without using a power source such as an engine or a motor in case of an emergency.
- Preferably, the present invention further has the following configurations.
- (1) The first footboard portion 12b slides on the door
main body 7 by its own weight to cover the window 5c from the forward full open state of the door to the close state of the door.
