Description

  The present invention relates to a platform door structure of a platform door device that is provided on a platform and forms an entrance / exit corresponding to an entrance / exit of a railway vehicle.

  As a door device installed on a platform, many side-opening slide devices have been disclosed (see, for example, Patent Document 1). However, in the case of a side-opening slide type door device, a fixed installation part is required as a door storage part, and the opening / closing position is determined in advance. There is a problem that it is difficult to deal with. As a solution to this problem, there is disclosed a side-opening slide type door device that includes a plurality of rails and selectively moves a door to flexibly form a frontage (see, for example, Patent Document 2).

On the other hand, Patent Document 3 describes a door device of a type that opens and closes a door in the vertical direction instead of a lateral opening type. Even in this door device, the frontage can be formed flexibly by selectively opening the door.

  The door device described in Patent Document 3 has a structure in which the door is stored in a recess formed in the platform, and a gap is generated between the doors arranged side by side. The gap between the doors may impair the design, and may cause a wind to be caught in the gap when the train passes through the station and draw in baggage or clothes.

  The present invention was created in order to solve such problems, and an object thereof is to provide a home door structure that shields a gap between parallel home doors.

In order to solve the above-mentioned problems, the present invention provides a platform door structure in which a plurality of doors arranged side by side on a platform are opened and closed in a vertical direction, and is installed on a track side from a side edge portion of the platform. a guide frame for guiding the direction, in at least one side of the door, the home, characterized in that a cover covering the gap between the door between the adjacent provided the door integrally, is provided A door structure was adopted.

  According to this platform door structure, a gap generated between adjacent platform doors can be shielded by the cover provided on the side portion of one platform door, and the platform door is excellent in design. In addition, it is possible to prevent the wind from being caught in the gap when the train passes through the station.

  Moreover, in this invention, it can be set as the platform door structure characterized by the buffer part being provided in the surface which faces the door which the cover adjoins.

  According to this platform door structure, even if the cover comes into contact with the other door that is in the closed state when one of the adjacent doors opens and closes, only the buffer provided on the cover contacts the other platform door. Therefore, the other parts of the cover and the other door structure itself are not damaged. Further, even when a plurality of doors open and close at the same time, no backlash occurs between the operating doors, and the generation of abnormal noise can be prevented. Furthermore, when a door is in a closed state, even if one door is pushed by a person's collision or the like and comes into contact with another adjacent door, it can absorb the impact and prevent the generation of abnormal noise. it can.

  ADVANTAGE OF THE INVENTION According to this invention, when installing an up-and-down open / close type platform door apparatus, the clearance gap between the home doors arranged in parallel can be shielded.

Hereinafter, an embodiment of an up / down opening / closing platform door device to which the platform door structure is applied will be described first, and then the structure between the platform doors will be described.
1 and 2 are external perspective views of a platform door device to which the platform door structure according to the present invention is applied as viewed from the track side and from the platform side, respectively, with some doors open. Shows the state.

  The platform door device 1 forms an entrance / exit corresponding to the entrance / exit of a railway vehicle, and is arranged in parallel along the side edge S of the platform PH and outside the side edge S (track side). , A plurality of doors 2 that open and close in the vertical direction, and a door passing step 3 that is provided for each door 2 and that opens and closes outside the side edge S of the platform PH (on the track side). The door 2 is a rectangular structure that is long in the vertical direction and includes a panel 40 and a door frame 41 that serves as a frame of the panel 40 and includes a cover 60 on at least one side. The door 2 moves up and down on the outer side of the side edge S at the same time as the step 3 rotates upward. When the door 2 rises and closes, the upper end of the door 2 is positioned approximately at the height of the adult male's chest. In the open state, the entire door 2 is stored below the side edge S.

Normally, the doors 2 are all closed as shown in part A of FIG. 1 and FIG. 2, and when the vehicle enters and stops, the door 2 facing the entrance of the vehicle is like part B of FIG. 1 and FIG. Open to. In this embodiment, it is the structure which the some door 2 opens with respect to one entrance / exit. Although the width dimension of the door 2 is determined as appropriate, as an example, it is set to a dimension that can be opened and accommodated with respect to a vehicle entrance / exit having a frontage dimension of 1.5 meters.
FIG. 3 is a plan view showing a case where a plurality of doors 2 are opened corresponding to the entrance / exit of the vehicle. FIG. 3 (a) shows a case where the vehicle stops at a normal position. 2d opens. When the same vehicle stops slightly from the normal position and cannot be handled by the doors 2a to 2d, the five doors 2a to 2e facing the entrance / exit are opened as shown in (b). . As the width dimension (pitch) of the door 2 is reduced, the entrance / exit entrance dimensions of the door 2 can be matched to the entrance / exit entrance dimensions for all vehicles having different entrance / exit positions and entrance dimensions.

  4 is an external perspective view of Step 3, and FIG. 5 is a side view illustrating the door 2 in a closed state. Step 3 is provided so as to open and close on the outer side (track side) than the side edge S of the platform PH as described above. Step 3 is a structure that opens and closes around a horizontal axis along the side edge S, and rotates around the side edge S as a rotation base end. When the door 2 is lowered, that is, when the door 2 is in the open state, the step 3 is such that the step surface 3a is horizontal and is substantially flush with the platform PH, and the tip extends toward the vehicle entrance / exit. It will be a footboard when getting on and off.

  When the door 2 is raised, that is, when the door 2 is closed, as shown in FIG. 5, the step 3 is rotated upward and in the home direction inside the home from the door 2. By configuring Step 3 to rotate from the end of the platform PH toward the center of the platform, it is possible to have a function to regulate the feet when rushing in and to run psychologically because it rotates so as to rise forward. Boarding can be suppressed.

  As described above, the plurality of doors 2 that are arranged side by side along the side edge S of the platform PH and open and close in the vertical direction outside the side edge S, and the side edges of the platform PH are provided for each door 2. If the door has step 3 that opens and closes outside S, it is not necessary to provide a recess for storing the door on the platform PH, so that the platform PH is not modified so much. The platform door device 1 can be easily installed around the side edge S of the platform PH.

  When step 3 is formed of a flat plate, when only one of the two adjacent steps 3 rotates upward, a gap is formed at the side of the rotated step 3. When this gap is large, a pair of side plates 3b is formed in step 3, and the gap generated between adjacent steps 3 may be closed by this side plate 3b. The shape of the side plate 3b is appropriately determined according to the gap shape so as not to interfere with the door 2.

  In this embodiment, the door 2 is formed in the curved shape which becomes convex toward the track side. As an example of the curved shape, a shape having a constant radius of curvature from the upper end to the lower end is taken into consideration in view of economy and design. The center position of the radius of curvature is, for example, on the surface of the platform PH or in the vicinity of the surface. When the door 2 has a curved shape, it is desirable that the opening / closing operation is not linear movement, but is configured to rotate and open along the curved shape. That is, when the door 2 has a certain radius of curvature, the door 2 is rotated and opened around the center of curvature. Thereby, the space required for the movement of the door 2 is small, and the dynamic design is beautiful.

  When the door 2 is raised most, the upper end of the door 2 is located on the inner side of the platform with respect to the side edge S of the platform PH. In FIG. 5, the distance in the home width direction between the upper end of the door 2 and the side edge portion S is indicated by a symbol L. As described above, when the door 2 is lifted, if the upper end of the door 2 is positioned on the inner side of the home with respect to the side edge S, the upper body is regulated by the upper end of the door 2, thereby the side edge of the upper body. Protrusion from S to the track side is prevented. Moreover, since the space at the foot can be used up to the side edge portion S, the foot does not become cramped at the time of congestion or the like.

  One structural example of the door 2 will be described based on FIGS. 6 and 7 with reference to FIGS. Hereinafter, with respect to both surfaces of the door 2, the surface facing the platform side is referred to as an inner surface, and the surface facing the track side is referred to as an outer surface. FIG. 6 is a side sectional view of the door including the drive mechanism, where (a) shows a closed state and (b) shows an open state. FIG. 7 is a cross-sectional view taken along the line CC in FIG. 6B, and shows the relationship between the door and the guide frame.

  The door 2 is a plate-like structure in which a panel 40 is fitted in a door frame 41 as shown in FIG. A boss 42 is formed below the side surface of the door frame 41 and is rotatably engaged with a boss hole 37 formed in the link 36 as shown in FIG. The guide frame 25 determines the vertical opening / closing track of the door 2, and is inserted into the recess of the U-shaped guide frame 25 (see also FIG. 2) as shown in FIG. A guide part G is provided. The surface of the guide portion G on the home side and the track side is provided with four rollers 38, 39, 38, 39 in total, each having two height positions (up and down directions in FIG. 6A). The roller 38 is in contact with the inner surface 25r of the guide frame 25 on the track side, and the roller 39 is in contact with the inner surface 25p of the home side. As described above, the rollers 38 and 39 are brought into contact with the inner surfaces 25r and 25p of the guide frame 25, thereby realizing a smooth vertical opening and closing operation of the door 2.

  The platform door device 1 has a plurality of doors 2 arranged side by side as shown in FIGS. 1 and 2, and adjacent to each other as shown in FIG. 7 in order to prevent the vertical opening and closing operations of the doors 2 from interfering with each other. A gap D is provided between the doors 2a and 2b. The presence of the gap D impairs the design and may cause problems such as wind pulling into the gap when the train passes through the station, and pulling baggage and clothes. A cover 60 that covers the gap D is formed. The cover 60 is formed on one of the door frames 41 of the adjacent doors 2a and 2b (the door 2a in FIG. 7), the guide frame 25 of the door 2a, the gap D, the guide frame 25b of the door 2b, and the door frame 41b. It has an airfoil shape that covers part of it. A buffer 61 is provided at a position facing the guide frame 25b (door frame 41b) of the door 2b which is the front end side of the cover 60, and the door 2a and the guide frame 25b (door frame 41b) on the door 2b side are in contact with each other. At the same time, the impact can be reduced and the generation of abnormal noise can be prevented.
