JP2002220047A - Platform door device of bi-part sliding type - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a bi-part sliding type platform door device having no lintel in the over-part as improvement of a conventional arrangement based on the bi-part sliding system in which when the left and right door pieces are shut, it may happen that any door inclines to the vehicle side or to the opposite side in its forefront away from the door pocket even if the part near the door pocket is in the vertical attitude approximately. SOLUTION: The tip of a movable shaft installed on one of the doors and capable of moving in the horizontal direction relative to the door is attached to a link, and the other end of the link is attached to a key, which is arranged moving to the left and right in compliance with the left-right motions of the movable shaft so that it penetrates a receptacle provided in the door on the opposite side.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double door system door device provided on a platform corresponding to the 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 rush hours, the number of falls from the platform has increased, and such accidents have been reduced. For this reason, stations that install platform doors on platforms are increasing. In consideration of not only safety but also services such as cooling and heating for the home door, there is a case where a method is adopted in which the platform is formed as a single room closed to the track portion. In that case,
A door is provided on the upper part, and the door is supported by the door and the lower rail, so that the door does not fall down or tilt. However, in general, in order to reduce costs and the like, a method is adopted in which doors and door pockets are set to a height at which safety can be ensured, and a door is not provided. The present invention relates to an improvement of a home door device having no upper gate or the like at an upper portion. FIG. 3 is a prior art in which a platform and a vehicle are viewed from above.
1 is a platform, 2 is a door pocket, 3 is a door, 4 is a platform fence, 5 is a vehicle, and 6 is a vehicle side door.

[0003]

By the way, in the case of a double-opening system without a gate at the top and when the left and right doors are closed, at the tip farthest from the door pocket, the door tilts toward the vehicle or in the opposite direction. In addition, when a force is applied by a passenger, there is a possibility that an even greater inclination may occur, and there is a problem that it is substantially difficult to realize that the left and right doors are aligned in a straight line as shown in FIG. Was.

SUMMARY OF THE INVENTION The present invention has been made in order to solve such a problem. In a double door type home door device which does not have a gate at an upper portion, the present invention has been made in view of the above. A movable shaft attached to the door and movable in a horizontal direction relative to the door, a link rotatably attached to the door at one point at an intermediate portion, and one end rotatably attached to a tip of the movable shaft; A key rotatably attached to the other end of the link, a guide for guiding the key in a horizontal direction, a receiver attached to another door corresponding to the door, and through which the key can pass.

According to a second aspect of the present invention, there is provided a double door type home door device having no ditch at the top thereof, wherein the movable shaft is attached to one of the doors and is movable in a horizontal direction relative to the door. Attached to other doors corresponding to
A receiver through which the movable shaft can penetrate;
The details of the present invention will be described with reference to the drawings.

[0006]

FIG. 1 shows an embodiment of the present invention, in which (a) shows a state in which a door is closed, and (b) shows a state in which the door is opened. In the figure, 11 is an electric motor, 12 is a driving pulley, 13 is a driven pulley, and 14 is a belt, which are attached to the door pocket 2. 15 is a fixture, which is attached to the door 3,
In addition, the belt 14 is configured to be sandwiched therebetween. By doing so, the drive side pulley is
When 12 rotates, the belt moves left and right, and is dragged or pushed by the belt, and the door 3 opens and closes left and right. Reference numeral 16 denotes a linear guide rail attached to the door pocket 3, and reference numeral 17 denotes a linear guide bearing which supports the door 3 and can move in the left-right direction. The above is the prior art.

For example, 20 is an electromagnetic solenoid, 21 is a movable shaft of the electromagnetic solenoid, 22 is a link, 23 is a key, 24 is a guide, 25
Are penetration receivers, which are parts according to claim 1 of the present invention. In the vicinity of the entrance of the through hole, the tip of the key, and the portion that enters the receptacle, measures such as providing chamfers of appropriate dimensions with respect to the inclination of the door are taken. The same reference numerals as those in FIG. 3 indicate the same structure and the same function. When the electromagnetic solenoid is excited to pull the movable shaft 21 of the electromagnetic solenoid 20 to the right with the door closed, the link 22 rotates counterclockwise around the point A, and as a result, the key 23
Guided to move to the left. Since the receiver 25 is attached to the opposite door 3 of the pair, the key enters the through hole of the receiver, and as a result, the left and right doors are connected by the key 23, and the inclination and inclination are corrected. . Point A is determined so that the dimension from the point A of the link to the connection point with the movable shaft and the dimension from the point A to the connection point with the key are appropriate according to the stroke of the movable shaft and the stroke of the key. Can be The connection point between the link 22 and the key 23 tends to move in an arc along with the movement of the movable shaft.
The key has a structure that cannot move in the vertical direction. Therefore, if the connection point between the link 22 and the key 23 is simply a hole, there is a possibility that it will be difficult to solve the problem. You only have to consider it.

FIG. 2 shows an embodiment of the present invention according to claim 2, wherein (a) shows a state in which the door is closed, and (b) shows a state in which the door is open. In this figure, the conventional technology for driving the door and the like are omitted. In the drawing, the same reference numerals as those in FIG. 1 have the same structure and the same function. When the movable shaft is sufficiently strong in strength and the stroke is sufficiently large, the movable shaft is passed directly through the receiving member on the opposite side as shown in this figure without using a link or a key guide as shown in FIG. The configuration of the device is greatly simplified.

In the above description, the movable shaft uses an electromagnetic solenoid. However, it is needless to say that the use of an electric actuator or the like is an example of the present invention.

[0010]

According to the present invention, in a double door type home door device having no gate, when the door is closed, the tip of the door is liable to be inclined in the vehicle direction or in the opposite direction,
In addition, although there is a possibility that the vehicle may be further inclined when receiving force from passengers, the present invention can reduce the difference between the left and right doors.
