Description

Movable home fence

The present invention relates to a movable platform fence that is installed in the vicinity of a side edge of a platform and partitions the platform and a track.

In recent years, the installation of door devices or gate devices called platform doors, movable platform fences, etc. has been spreading as a countermeasure for safety measures at railway stations, and it is considered that the spread will continue in the future.

In the conventional platform door and the movable platform fence, a space is formed between the edge of the platform and the door body in the closed posture. Therefore, there is a possibility that a passenger who rushed into the vehicle at the last minute accidentally left behind in the space between the vehicle (the door is already closed) and the platform door or movable platform fence in the closed position. It was. Usually, the danger is avoided by detection by the detection sensor and visual observation of the conductor, but the detection sensor may not operate due to a failure or the like, and the visibility from the conductor may be poor.

In addition, the platform door and the movable platform fence that are actually installed currently have a configuration that depends on the arrangement of the doors of the vehicle, and cannot be adapted to platforms operated by vehicles with different vehicle door pitches. However, in reality, there are routes on which a wide variety of vehicles run simultaneously, and the number, size, position, etc. of the doors differ depending on the type, application, and type of the vehicle. There is a demand for a movable home fence.

Numerous proposals have been made for platform doors and movable platform fences that are intended to accommodate different types of vehicles with different door arrangements. The proposed apparatus uses a plurality of bowl-shaped doors as shown in Patent Document 1, a low-profile door bag as shown in Patent Document 2, and a door body that can be moved in and out of the door bag. It can be roughly divided into a movable home fence using and.

In the thing using the bowl-shaped door body as shown in patent document 1, in order to move the door body with the height dimension higher than the height of the person from the platform floor surface, the door frame is moved. There is a possibility that the entire apparatus including the device may be large and increase the cost, and there is a problem that visibility and visibility from the conductor are bad when passengers get on and off the vehicle.

The movable platform fence consisting of a low-profile door pocket and door body has a simpler structure than that using a saddle-like door body, and has good visibility and visibility from the conductor when passengers get on and off the vehicle. Moreover, what made the door pocket movable is proposed in the movable home fence which consists of a low-profile door pocket and a door body (patent document 3, patent document 4). In order to flexibly cope with different types of vehicles having different door arrangements, a configuration in which the door pocket is movable is advantageous.

In order to realize a home fence that employs a movable door pocket, there is a problem of how to stably stand and run an unstable door pocket that cantilevered the door body. Patent Document 4 also mentions that when the wind pressure of a passing train acts on the door pocket, or when a person leans against the door pocket during a rush hour, the door pocket falls down. Although it is intended to solve this problem by giving a characteristic to the configuration, the configuration of the traveling mechanism becomes complicated, which may increase the cost.
