JP 2000-016280 A

  In the prior art home door, the slide door is heavy, and therefore, a support structure for slidably supporting the slide door with respect to the door pocket must be configured firmly. In the conventional platform door, the slide door extends upward from the position near the upper surface of the platform and is supported at the lower edge of the slide door. The sliding door must be sufficiently robust against the moment caused by the crowd load acting on the track side. Therefore, the prior art platform doors are heavier and larger, which increases the manufacturing cost.

  Also, installing a platform door on the platform can reduce the labor of station staff located on the platform for safety confirmation when the train arrives, in addition to preventing falling people. However, there is a problem that it becomes impossible to see the track side from the platform side. In particular, there is a problem that even if a person is hiding or an object is placed behind the door pocket of the platform door, the platform cannot be seen from the blind spot.

  An object of the present invention is to provide a platform door device that is capable of solving such problems of the prior art, has a small blind spot, and has reduced manufacturing costs and installation costs.

According to a first aspect of the present invention, there is provided a platform door device disposed along an edge of the platform, a base fixed to the upper surface of the platform, a door bag attached to the base, a platform of the platform, A sliding door provided in a direction along the edge so as to be movable forward and backward with respect to the door pocket; a direction attached to the base and receiving a lower edge member of the sliding door along the edge of the platform; A slidably supporting and guiding member, and a cushion attached to the door of the sliding door ,
The base has a plurality of legs are arranged at a predetermined distance above the upper surface of the platform by the legs, the sliding door is disposed above said base The gist of the platform door device is characterized in that the cushion has a protruding portion that extends downward beyond the lower edge member of the slide door .

The base comprises a stationary base that is fixed to the platform by the legs, and a movable base that is pivotably attached to the stationary base in a horizontal direction, and the door pocket includes the door A stationary door pocket attached to the stationary base and a movable door pocket attached to the movable base and coupled to the stationary base so as to be rotatable in the horizontal direction together with the movable base.
The slide door may be formed of a frame body made up of a plurality of extruded section members.

  According to the present invention, the blind spot when the track side is viewed from the platform side is reduced by arranging the base above the upper surface of the platform and arranging the sliding door above the base. Furthermore, since the overall height of the platform door is determined in general, the support guide mechanism for the slide door is provided by disposing the base above the platform from above and disposing the slide door above the base. Can be placed at a position higher than the top surface of the platform (position close to the upper end of the slide door), and the moment acting on the support guide mechanism is reduced by the crowd load acting on the upper edge of the slide door from the platform side to the track side. As a result, the support guide mechanism can be simplified, and the manufacturing cost of the platform door device can be reduced.

  Furthermore, by forming the slide door from a rectangular frame, wind load (the load in the horizontal direction when the wind hits the slide door) becomes a conventional slide door (the door is constituted by a panel-like member). Compared with a platform with an embankment structure or the like, the foundation reinforcement work or the like is not necessary (or reduced), so that the cost of the home door installation work is reduced.
