[0005]

In the present invention, since the sliding member slides in the advancing direction of the door roller by the moving means, when the horizontal sliding door is opened, the sliding member is moved laterally by a collision with the facing surface when the horizontal sliding door is closed. The horizontal sliding door slides along the upper frame and the lower frame while the sliding body pushed into the sliding door remains stored in the horizontal sliding door. Also, when the horizontal sliding door in the opened state is closed, the sliding body housed in the horizontal sliding door slides in the advancing direction of the door roller. When the sliding body collides with the facing surface, the sliding body is pushed into the sliding door, and the shock is buffered by the buffering means for buffering the shock of the sliding body. The sliding body may be provided on one side surface or both side surfaces of the horizontal sliding door in the sliding direction. Further, one or more sliding bodies may be provided on the side surface of the horizontal sliding door.

In the moving means according to the second aspect, since the friction surface of the arm integrated with the sliding body is brought into contact with the door roller, the friction surface is sent out in the traveling direction of the door roller by the rotation of the door roller. Therefore, the sliding body integrated with the arm slides in the traveling direction of the door roller. When the sliding door is closed and the sliding body collides with the facing surface, the arm slides together with the sliding body in the direction opposite to the advancing direction of the door roller. On the contrary, the shock absorbing means absorbs the shock that the sliding body receives while moving while causing friction. Further, when the horizontal sliding door is opened, the sliding surface can be opened while the sliding body is accommodated in the horizontal sliding door due to the friction surface of the arm.

According to a third aspect of the present invention, the range of movement of the sliding body is limited by the stopper, and the door wheel is separated from the friction surface of the arm if the door wheel is in constant contact with the friction surface of the arm within this movement range. Instead, the friction surface can be sent out to move the sliding body within the moving range.

According to the fourth aspect of the cushioning means, the shock received by the sliding body is cushioned by the compression of the air enclosed between the sliding body and the cylindrical body.

In the present embodiment, the frictional force between the friction surface 12 of the horizontal arm 11 provided integrally with the sliding body 6 and the door roller 2 in contact with the frictional surface 12 causes the sliding body 6 to move in the tubular body 3. The air 10 enclosed between the cylinder body 3 and the sliding body 6 by pushing is compressed and is stronger than the restoring force of the compressed air 10 and the sliding surface 6 receives a shock, so that the friction surface of the arm 11 is 12 is a frictional force capable of moving in the opposite direction to the traveling direction of the door roller 2.

When the horizontal sliding door 1 is closed to close the passage, the sliding body 6 is pushed into the cylindrical body 3 as shown in FIG. 2, and the side surface of the horizontal sliding door 1 comes into contact with the vertical frame 17. ing. As shown in FIG. 1, if the horizontal sliding door 1 is opened and the passage is opened, the friction surface 12 of the arm 11 is moved by the rotation of the door roller 2 in the moving direction, that is, in the horizontal sliding door 1. Trying to do this, arm 11
Is restricted from moving due to the contact of the stopper 13 of the cylindrical body 3, the door roller 2 advances while idling on the friction surface 12, and the arm 11 remains in the same position without moving back and forth.

[0016]

As described above, according to the present invention, the impact of the horizontal sliding door colliding with the opposing surface is greatly affected by the sliding member projecting outside the horizontal sliding door absorbed by the moving means by the shock absorbing means. The shock absorber and the shock noise are significantly reduced, the fingers are not pinched, and the injury is prevented. In addition, the sliding body can be surely projected to the outside of the horizontal sliding door by the moving means only when the side surface of the horizontal sliding door on the side where the sliding body is provided is moved to the facing surface side, and the horizontal sliding door can be opened. When the passage is opened, the sliding member is certainly stored in the horizontal sliding door by the moving means, so that the sliding member does not obstruct the passage of passengers.

According to the present invention, a very simple structure in which the door roller is brought into contact with the friction surface of the arm integrated with the sliding member and the door roller is rotated to slide the sliding member in the advancing direction of the door roller. However, the friction surface of the arm can be easily and surely moved by the rotation of the door roller by using the rotation of the door roller of the horizontal sliding door itself as the driving force to move the sliding body.

According to a third aspect of the present invention, a stopper for limiting the moving range of the sliding body is provided, and if the door wheel is brought into contact with the friction surface within this moving range, the door wheel is always in contact with the friction surface of the arm. Thus, the movement of the sliding body can be surely moved within the movement range.

Further, as the cushioning means, in the case of the fourth aspect, although the structure is a very simple structure in which air is enclosed between the cylindrical body and the sliding body, the shock is securely cushioned and the collision force and the collision noise are generated. It has also been significantly reduced, and it is possible to reliably prevent pinching of fingers and the like. In addition, it can be manufactured at a very low cost.
