Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a home door device provided on a platform corresponding to an entrance of a railway vehicle.

[0002]

2. Description of the Related Art In recent years, the number of stations having platform doors on platforms has been increasing. On the Shinkansen, home doors are provided to prevent accidents from occurring due to high-speed trains such as Atami and Shin-Kobe stations. In addition, the concentration of the population is remarkable, such as in the Tokyo metropolitan area, and as a result, in places where there is no congestion, such as the station platform during a rush hour, the number of accidents falling from the platform has increased, and such accidents have been reduced. For this reason, stations that install platform doors on platforms are increasing. FIG. 6 is a prior art in which a platform and a vehicle are viewed from above, where 1 is a platform, 2 is a door pocket, 3 is a home door,
4 is a platform fence, 5 is a vehicle, and 6 is a vehicle side door. When the number of entrances and exits per vehicle is small, the pitch between adjacent entrances and exits is long, so that adjacent door bags do not interfere with each other in dimension as shown in the figure, and the home fence 4 is placed between adjacent door bags. It is common to provide.

[0003]

By the way, in the case of the leading vehicle or the rearmost vehicle, the distance between the door at the entrance / exit next to the crew compartment and the door of the crew compartment is short. In addition, in order to prevent the vehicle from getting in and out of the vehicle even if the vehicle stops at a certain position, the home door needs to be larger than the vehicle door. In such a case, it may not be possible to provide a home door at each of the passenger entrance and exit next to the crew cabin and the crew entrance and exit. In addition, the number of doors per vehicle, such as recent vehicles, is not limited to the first vehicle and the last vehicle, and the number of doors per vehicle is also increasing, such as 6 doors, and stations where such vehicles stop Then, the distance between adjacent entrances has also become shorter. For this reason, in the case of a conventional home door in which one door is stored in one door pocket, the door bags of adjacent entrances and exits are dimensionally interfered with each other, so that home doors cannot be provided for all entrances and exits. Occurs.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and a home door is provided at a position on a platform corresponding to an entrance of a vehicle. In a home door device provided with a driving mechanism for opening and closing a home bag and a home door,
The home door housed in the same door pocket is constituted by a plurality of doors, and is provided with an interlocking mechanism for opening and closing the plurality of doors in an interlocked manner. Hereinafter, details of the present invention will be described with reference to the drawings.

[0005]

FIG. 1 shows an embodiment of the present invention, in which a vehicle and a platform are viewed from above.
In the figure, 7A and 7B are linked, and two doors function as one door. Reference numeral 8 denotes a door pocket for storing 7A and 7B, and 9 denotes a platform side door corresponding to the crew cabin. Reference numeral 10 denotes a crew room, and 11 denotes a door of the crew room. The same reference numerals as those in FIG. 5 have the same functions and the same configurations. In this way, by configuring the home door with a plurality of doors, the size of one door can be reduced,
The width of the door pocket can be reduced, and as a result, it is possible to provide a home door for each of the entrances even at locations where the distance between the entrances is short.

FIG. 2 is a conceptual diagram showing an example of an interlocking mechanism when two doors constitute one home door. In the figure, reference numerals 21 and 22 denote recesses provided in the doors 7A and 7B, and serve as guides. Reference numeral 25 denotes a lever, reference numeral 23 denotes a pin connecting the lever 25 to the door 7A, reference numeral 24 denotes a pin connecting the lever 25 to the door 7B, and reference numeral 26 denotes a fulcrum provided on the lever 25. Now, the dimension L1 between the fulcrum 26 and the pin 23 and the distance L2 between the pin 23 and the pin 24 are made equal. FIG. 3 is a diagram showing a cross section taken along line AA of FIG. 2, in which a pin 23 penetrates a lever 25 and the other end is a concave guide 21 of a door 7A.
Is inside. Similarly, the pin 24 penetrates the lever 25 and the other end enters the recess guide 22 of the door 7B.

When the point B on the lever 25 is pulled with some force, the door 23A moves leftward due to the action of the pin 23. Similarly, the door 7B also moves to the left by the action of the pin 24, but since the ratio of the distance from the fulcrum 26 to the pin 23 and the distance from the fulcrum 26 to the pin 24 is 1: 2, the door 7A The moving distance of the door 7B is twice as long as the moving distance of the door 7B. When the door is closed from the open state, if the point B on the lever 25 is pushed rightward with some force, the door 7 is closed.
A and 7B move rightward in a one-to-two relationship and close. B
As a method of applying a force to a point, the rotational force of the electric motor may be converted into a linear motion in the horizontal direction and applied, or an empty cylinder may be used.

As described above, by providing the interlocking mechanism for opening and closing the doors 7A and 7B in conjunction with each other, the home door can be folded and stored in the door pocket, and the width of the door pocket can be reduced. . In the above description, an example in which two doors are used as one home door has been described. However, the present invention does not limit the number of doors to two, and it is necessary to further reduce the width of the door pocket. In this case, one home door may be constituted by a large number of doors.

Although FIG. 1 has been described with reference to a vehicle having a crew cabin, the present invention can be applied to a home door corresponding to a vehicle having a short distance between doors such as a five-door vehicle and a six-door vehicle. Needless to say. In the above description, the double-opening home door has been described. However, it goes without saying that the present invention can also be applied to a single-opening type home door.

FIG. 4 is a conceptual diagram showing another example of an interlocking mechanism when two doors constitute one home door.
In the figure, 41 is a rack gear provided in the door pocket, 43, 4
Reference numeral 4 denotes a pinion gear provided on the door 7A, and 43 and 44 are mechanically connected by a belt 45 or the like so that they rotate at the same rotational speed. The reference numeral 45 does not need to be related to the belt, and may be, for example, a chain. Reference numeral 42 denotes a rack gear provided on the door 7B. With this configuration, when the door 7A is moved rightward at the speed V, the door 7A
B moves rightward at a relative speed V with respect to the door 7A, and eventually the door 7B moves rightward at twice the absolute speed of the door 7A, and the two doors can be opened and closed in conjunction. Door 7B
As the power for moving the motor, the rotational force of the electric motor may be changed to a linear motion, or may be moved by an air cylinder or the like.

In the above description, an example has been described in which a plurality of doors constituting one home door start moving at the same time as an interlocking mechanism. However, interlocking does not necessarily have to start at the same time. FIG. 5 is a top view of the relationship between the doors 7A and 7B, and is another example of the interlocking mechanism. And
A projection 31 is provided on the door 7A, and projections 32 and 33 are provided on the door 7B. An interlocking mechanism that applies power from the power source only to the door 7B is provided. When the door is closed, the door 7B first moves rightward,
When the projection 32 hooks the projection 31, the door 7A is also pulled rightward and closed. When the door is opened, only the door 7B first moves leftward, and when the projection 33 hits the projection 31 of the door 7A, the door 7A is closed. Needless to say, an interlocking mechanism that moves to the left is also an example of the present invention.

[0012]

According to the present invention, the width of the door pocket can be reduced because the home door is constituted by a plurality of doors, and when the door is stored in the door pocket, it can be folded and stored. It is now possible to provide a home door corresponding to each entry / exit point when the distance is short.
