Definitions
- the present invention relates to a footplate apparatus for a connecting pathway between vehicles.
- FIG. 8 A conventional footplate apparatus for a connecting pathway between vehicles of a train is shown in Figs. 8 and 9.
- This footplate apparatus is divided into two sections in a direction of the railroad.
- These two footplates 1 and 2 are vertically movably supported by hinges 3 and 4, respectively, but are restricted not to move downwardly from their horizontal positions, and a distal portion of the upper footplate 2 is mounted on the upper surface of a distal portion of the lower footplate 1 which is formed of a single plate.
- the upper footplate 2 comprises a main plate 5 and auxiliary plates 6 and 7.
- the main plate 5 is formed of a single plate including opposite slant portions which extend from the vicinity of a distal-end center portion 5a in a direction of the vehicles toward opposite sides.
- the auxiliary plates 6 and 7 are vertically movably attached to edges of the above-mentioned opposite slant portions through hinges 8 and 9, respectively.
- Figs. 8 and 9 show a type of the footplate apparatus where a connecting hood which constitutes the connecting pathway is divided into two sections in the direction of the railroad, and these two hood sections 10 and 11 are detachably connected by free-end frames 12 and 13.
- the lower footplate 1 is provided on the side of the vehicle 14 while the upper footplate 2 is provided on the free-end frame 12.
- the similar footplates as described above are mounted between the free-end frame 13 and the vehicle 14' on the other side, and the similar components as described above are denoted by common reference numerals with primes so that their explanations will be omitted.
- the main plate 5 of the upper footplate 2 is formed of a single plate from a portion adjacent to the hinge 4 to the distal-end central portion 5a. Consequently, when the pitching amount is zero, the footplate apparatus is in a state shown in Fig. 10A, but when pitching of the vehicles occurs as shown in Fig. 10B (Fig. 10B illustrates the case in which the pitching amount is 55 mm), the hinges 3 and 4 of the footplates 1 and 2 are located at different levels. In such a case, the upper footplate 2 is pressed upwardly, as shown in Fig.
- the distal-end center portion 1a of the lower footplate 1 is moved toward the proximal side of the lower surface of the upper footplate 2 and presses the main plate 5 of the upper footplate 2 further upwardly, thereby forming an even larger gap D 2 between the distal-end center portion 5a of the upper footplate 2 and the upper surface of the lower footplate 1.
- An object of the present invention is to provide a footplate apparatus for a connecting pathway which solves the problem of danger at the time of pitching which has not been solved by the conventional structure described above.
- a footplate apparatus for a connecting pathway comprising a pair of footplates, a first footplate being extended below a second footplate, wherein the second footplate is divided at at least one portion over its entire length in a direction perpendicular to a direction of the railroad so as to form a first footplate section and a second footplate section in the direction of the railroad, and these footplate sections are vertically movably connected to each other.
- the second footplate may be divided into more sections in the direction of the railroad.
- Figs. 1 and 2 are a vertical cross-sectional view and a horizontal cross-sectional view showing footplate apparatus of the type in which a connecting pathway between coupled vehicles 20 and 21 is covered with a connecting hood divided into two sections 22 and 23.
- Reference numerals 24 and 25 denote free-end frames of the two hood sections 22 and 23, respectively.
- Reference numeral 26 denotes a first footplate or a lower footplate which is provided on the first vehicle 20, and 27 denotes a second footplate or an upper footplate which is provided on the free-end frame 24.
- the upper footplate 27 is divided into a first footplate section 28 and a second footplate section 29 in a direction of the railroad, and the upper footplate 27 includes auxiliary plates 30 and 31 provided on opposite sides of the distal end of the second footplate section 29.
- the lower footplate 26 is formed of a single rectangular plate. A longer proximal portion of the lower footplate 26 is located along an end surface of the vehicle 20 and connected thereto vertically movably by a horizontal hinge 32 which is provided on the end surface of the vehicle 20, so that the lower footplate 26 will vertically move around the hinge 32.
- the lower footplate 26 further includes a downward movement preventing stopper (not shown) which allows the lower footplate 26 to move upwardly from the illustrated horizontal position but prevents it from moving downwardly.
- a distal portion 26a of the lower footplate 26 is bent slightly downwardly.
- the upper footplate 27 is divided into the first and second footplate sections 28 and 29 in the direction of the railroad.
- a proximal portion of the first footplate section 28 is pivotally connected to the free-end frame 24 by a hinge 33 which extends horizontally and perpendicular to the direction of the railroad so that the first footplate section 28 will vertically move around the hinge 33.
- a distal portion of the first footplate section 28 projects toward the above-mentioned lower footplate 26, and a distal end surface 28a of the first footplate section 28 is cut straight over the entire length along a direction perpendicular to the direction of the railroad.
- a proximal end 29a of the second footplate section 29 is located along the distal end surface 28a of the first footplate section 28, and the second footplate section 29 is vertically movably connected to the distal portion of the first footplate section 28 by a hinge 34 which extends horizontally and perpendicular to the direction of the railroad.
- the second footplate section 29 has a plane shape which is cut to have opposite slant portions which extend from the vicinity of a distal-end center portion 29b toward opposite sides of the proximal end portion.
- the hinges 32 and 33 are arranged at different levels such that when the pitching amount is 0 mm, the above-described first and second footplate sections 28 and 29 will be horizontally placed on the lower footplate 26 in the horizontal position.
- Reference numeral 35 denotes a sliding plate secured on the lower surface of the first footplate section 28 through a bracket 36
- 37 denotes a sliding plate secured on the lower surface of the second footplate section 29 through a bracket 38.
- the sliding plates 35 and 37 are slidably placed on the lower footplate 26.
- a slight gap is formed between the second footplate section 29 and the lower footplate 26. Consequently, the distal-end center portion 29b of the second footplate section 29 is bent slightly downwardly to decrease a gap between the distal-end center portion 29b and the lower footplate 26.
- auxiliary plates 30 and 31 are pivotally connected to the opposite slant portions of the second footplate section 29 by hinges 39 and 40, respectively.
- outer side portion 30a, 31a of the auxiliary plates 30, 31 have a shape which is cut to have slant portions which extend from the vicinity of the center toward sides of the proximal end portion.
- reference numerals 41 and 42 denote pressing device for pressing the free-end frames 24 and 25 toward each other
- 43 and 44 denote side panels
- 45 and 46 denote ceiling panels.
- the first and second footplate sections 28 and 29 of the upper footplate 27 are horizontally placed on the lower footplate 26 in the horizontal position. Therefore, the distal-end center portion 29b of the second footplate section 29 is located close to the upper surface of the lower footplate 26. Also, the distal ends of the auxiliary plates 30 and 31 are located close to the upper surface of the lower footplate 26.
- the distal-end center portion 29b maintains the gap-closed condition in which it is located close to the upper surface of the lower footplate 26.
- the auxiliary plates 30 and 31 are inclined downwardly, and their distal ends are located close to the upper surface of the lower footplate 26 so as to close the gaps therebetween.
- the first footplate section 28 of the upper footplate 27 is pressed further upwardly by the distal portion of the lower footplate 26, and the distal end of the first footplate section 28 moves apart from the upper surface of the footplate 26.
- the second footplate section 29 is inclined due to its own weight so that the distal portion is moved downwardly in substantially the same manner as described above, thereby closing the gap from the upper surface of the lower footplate 26.
- the auxiliary plates 30 and 31 are inclined downwardly, and their distal ends are located close to the upper surface of the lower footplate 26 so as to close the gaps therebetween.
- the lower footplate 26 in the first embodiment has an inclined surface extending toward the distal portion slightly downwardly at an angle ⁇ with respect to the horizontal plane when it lies down. Since the structure is otherwise the same as that of the first embodiment, the similar components as described above are denoted by common reference numerals so that their explanations will be omitted.
- a distal portion of the lower footplate 26 is located at a lower level than that of the first embodiment. Consequently, a first footplate section 28 of an upper footplate 27 is pressed upwardly by a less degree than that of the first embodiment, and the gap between a distal portion of the first footplate section 28 and the lower footplate 26 is decreased. Therefore, the height of bending of the first and second footplate sections 28, 29 is decreased, further lessening the above-mentioned danger.
- the first footplate section 28 of the upper footplate 27 in the first embodiment is further divided in the direction of the railroad so as to provide a third footplate section 28a, which is connected to a free-end frame 24 through a hinge 33 in substantially the same manner as described above.
- the first footplate section 28 and the third footplate section 28a are pivotally connected by a horizontal hinge 47 which extends in a direction perpendicular to the direction of the railroad.
- Retainer members 48 and 49 which abut against each other, are located on both sides of the hinge 47 and fixed on the upper surfaces of the first and third footplate sections 28 and 28a.
- the retainer members 48 and 49 have vertical contact surfaces 48a and 49a which abut against each other when the footplate sections 28 and 28a extend straight and which are separated from each other when the footplate sections 28 and 28a are bent downwardly from the hinge 47.
- the contact surfaces 48a and 49a prevent the footplate sections 28 and 28a extending straight from being bent upwardly but allow them to be bent only downwardly. Since the structure is otherwise the same as that of the first embodiment, the similar components as the first embodiment are denoted by common reference numerals so that their explanations will be omitted.
- the first and third footplate sections 28 and 28a are bent in the illustrated manner, and the upper footplate 27 is bent to have a less angular cross section than the foregoing embodiments, thereby further lessening the danger.
- the footplate sections 28 and 28a can be normally maintained to extend straight, so that a passenger or the like will have no trouble in walking on them.
- each of the above-described embodiments is an example of application of the type in which the connecting hood is divided into two sections, and the footplate apparatus are mounted between the free-end frames of the hood sections and the vehicles.
- the present invention may be applied to the type in which a single connecting hood is mounted between the vehicles, and the above-mentioned lower footplate 26 is provided on an end surface of the first vehicle while the above-mentioned upper footplate 27 is provided on an end surface of the second vehicle.
- the invention may be applied to a footplate apparatus which does not include the auxiliary plates 30 and 31 in the foregoing embodiments.
- the gap between one footplate and the distal end of the other footplate can be maintained at an extremely small size, thereby preventing danger such as a passenger or the like stumbling over the distal end of the footplate and falling down, or catching his or her foot between the footplates.
