DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telescopic gate having a door that can be extended and retracted by a vertical pantograph mechanism, and more particularly, to a telescopic gate that is installed on a corner ground using two doors that are arranged so that the directions of expansion and contraction are crossed. It is suitable as a telescopic gate to be used.

2. Description of the Related Art When a corner is opened or closed by using a door having a pantograph-type telescopic mechanism, two doors are respectively suspended on suspension bases erected on both sides of the corner opening. When the doors are extended, the two doors are arranged so that the moving ends of the two doors come into contact with each other at the corner of the corner, and the moving ends of the two doors are connected to each other. Usually, this type of connecting structure of a telescoping gate is configured such that a corner post rotatable toward the other door is pivotally connected to the moving end of one door so as to be rotatable in the horizontal direction, and the corner post and the other door are pivoted. The connection can be made by engagement devices provided respectively at the moving ends of the body.

However, in the conventionally known telescopic gate for corners, since the corner post is rotatable in the horizontal direction in accordance with the direction of the moving end of the other door, the corner post and the other door can be used. When connecting the moving end of the door body, it is necessary to connect the moving end of the other door body to the corner post by, for example, supporting the corner post by hand so that the corner post does not rotate and shake. For this reason, the connecting operation is extremely troublesome.

Japanese Unexamined Utility Model Publication No. 59-181199 discloses a telescopic gate in which a corner post provided at the moving end of one door is connected by a hinge mechanism which can be fixed at an arbitrary rotation angle. I have. According to this conventional technique, since the turning position of the corner post is fixed, the corner post does not turn when connected to the moving end of the other door body, and the operability is considerably improved, but the retractable gate door is contracted. In this state, the angle formed between the moving end of one of the doors and the corner post is kept constant, so that the corner post always projects and the open width of the corner is narrow. Was.

SUMMARY OF THE INVENTION An object of the present invention is to stabilize a corner post provided at a moving end of one of doors when a corner is closed by a door having two vertical pantograph mechanisms. It is an object of the present invention to provide a telescopic gate that can be adapted to a hanger-type door body that does not include a road surface traveling device that is suspended in a suspended state from a suspension column.

[0006]

The inventors of the present invention have made intensive studies in view of such circumstances, and as a result, two doors having a vertical pantograph-type expansion / contraction mechanism have been attached to suspension bases, respectively. The body is arranged so that the direction of expansion and contraction intersects, and a corner post that can be horizontally rotated toward the other door is pivotally attached to the moving end of one door, and the moving end and the corner post of the other door are connected. In a telescopic gate that can be connected to connect both doors, a corner column is provided with a drop bar device having a drop bar engageable with the road surface, and the drop bar is engaged with the road surface to move the other door body. The intended purpose has been achieved by restricting the horizontal rotation of the corner pillar that has been rotated by a predetermined angle toward the end.

Further, according to the present invention, two doors each having a vertical pantograph-type expansion / contraction mechanism are respectively attached to suspension columns, and both doors are arranged so that their expansion and contraction directions intersect with each other. A telescoping gate that pivotally attaches a horizontally rotatable corner pillar toward the other door body and abuts the moving end of the other door body and the corner pillar so that the two door bodies can be connected. A drop bar device is provided which has a drop bar which is suspended from a hanging post in a suspended state and which can be engaged with a road surface at a corner post, and the drop bar is engaged with the road surface and is directed toward a moving end of the other door body. The horizontal rotation of the corner pillar that has been rotated by an angle is restricted.

In particular, a so-called hanger type door body which is not provided with a road surface running device suspended in a suspended state from a hanging support column, the hanging at the moving end gradually occurs as the door body is extended, and the door ends are abutted. The moving ends of the two doors are not joined to each other in a parallel manner, so that the connecting operation is difficult. However, since a dropping bar device is provided on the corner post provided at the moving end of one door body, it is possible to reliably prevent dripping occurring at the moving end of one door body, and to perform a connection operation of both door bodies. It is possible to improve the durability of the door by reducing the load generated at the connecting portion between the door and the hanging post.

Further, according to the present invention, an operating portion of a drop bar device is provided on a side surface of a corner post facing a moving end of the other door body,
The operating part of the drop bar device is concealed by bringing the moving end of the other door body into contact with the corner post. Therefore, when both doors are connected, the drop bar device becomes inoperable, which is suitable for crime prevention.
