Description

Multi Folding Sliding Screen Door Unit

The present invention relates to a multi-folding sliding screen door device, and to a multi-folding sliding screen door device capable of controlling the degree of opening and closing of a screen door by interlocking with the doors constituting a train that stops on platforms such as railway stations and subway stations.

Platform Screen Doors (PSD) are a type of safety facility installed at the platform of railway stations and subway stations. They are normally closed but open and close automatically or manually according to the arrival of trains. It is mainly used in urban railway routes in some Asian and European countries, such as Korea, Hong Kong, Singapore, China, and Japan.

In Korea, the expression 'safety gate' has been used since 2013. However, in the actual field, 'PSD', an abbreviation for the English name of the screen door, is mainly used, and 'screen door opens', 'safety door opens', and 'platform safety door opens' in broadcasting when screen door is opened or closed. It is being used in a mixture of broadcasting, etc.

The screen door can be classified into a fully enclosed type, a semi-closed type, a handrail type, and a rope type according to the shape.

Fully enclosed screen doors (Platform Screen Doors, PSD) are screen doors that completely block from the platform to the ceiling. Since the track space and the platform are completely separated, the impact of noise, wind, or dust generated when a train enters the platform can be greatly reduced, and it helps to cooperate with the station. this is the form The disadvantage is that installation and maintenance costs are high, and incidental construction such as installation of a separate ventilation facility is unavoidable during installation.

A semi-enclosed screen door (PED: Platform Edge Door) is installed at a height of about 2m or more, just like the fully enclosed type, but the track and the platform are not completely separated and are a type of screen door with an open top. For this reason, the effect of blocking noise and wind is less than that of the fully enclosed type, but there is no probability of falling on the track and the construction cost is lower than that of the fully enclosed type.

A handrail-type screen door (HHPSD: Half Height Platform Screen Door) is one of the types of screen doors and is installed at about half the height of a closed type. It has the advantage of being cheaper to install compared to the sealed type, but it has little effect on blocking the train wind, and there is a high possibility of putting your face close to the track.

A Rope Screen Door (RSD) is a screen door that blocks between a platform and a train by moving a rope or bar up and down. Compared to other screen doors, installation and maintenance costs may be lower, but there is no effect such as blocking the train wind. On the other hand, even when trains with different door positions or train lengths share a platform, it can be operated with only a little calculation. It is impossible to operate in stations where is installed, but a rope-type screen door can be used.

As described above, in the case of the screen door, it is installed on the platform of the railway station and the main function is to secure the safety and convenience of the passengers entering and exiting. However, when both the platform and the opening and closing doors of the train are considered, the width of the screen door is set to a certain length. There are limitations that must be kept within. That is, when the screen door is opened, it is required to have a structure that enables the screen door in a temporarily folded state to be stored stably in a short time in a narrow space.

Patent Registration No. 10-1142521 shows a plurality of sliding doors that are connected to each other so that when one sliding door is moved, the other sliding door moves together, while the upper horizontal frame is formed in a double structure and between the two After spaced apart, various components for moving the sliding door are placed in the space between the double-structured frames to ensure that the automatic door provides an automatic door that makes the internal parts invisible when looking at the upper part from the bottom while the door is open. can

Conventionally, sliding doors were installed on platforms such as trains or train stations to enable smooth entry and exit of passengers, but even in the above case, there has been a limitation in the structure of the screen door installed on the platform. An object of the present invention is to provide a multi-foldable sliding screen door device capable of controlling the degree of opening and closing of the screen door by interlocking with the doors constituting the train stopping at the platform when the screen door is opened while stopping on the platform.
