Description

  The present invention relates to an elevator doorway device provided at a car doorway or a landing doorway.

  In a general elevator doorway apparatus, a vertical column (door column) is formed by a bent steel plate. This vertical column has a side wall part which constitutes a side wall of an entrance and a counter surface part which faces a door panel. In such a vertical column, as the door panel moves toward the fully closed position, an object such as a user's luggage may be sandwiched between the door panel and the vertical column, and the object may be drawn from the doorway to the door pocket side. .

  When such an object is drawn into the door pocket, the object may be caught on the end on the side of the fully open position in the entrance / exit direction of the facing surface portion. In this way, when the object is caught on the end of the vertical column at the fully open position, the object cannot be pulled out smoothly from the door pocket to the doorway side, and the object may be damaged when pulled out. It was.

  On the other hand, for example, in a conventional elevator entrance / exit device as shown in Patent Document 1, a convex portion is provided so as to close a gap between the vertical column and the door panel at the entrance / exit. By this convex part, the drawing-in of the object from the doorway side to the door pocket side is suppressed.

JP 2003-341964 A

  Here, like a conventional elevator entrance / exit device as shown in Patent Document 1, the object is prevented from being caught by narrowing the gap between the vertical column and the door panel. However, the gap dimension between the vertical column and the door panel needs to be set so as not to hinder the opening and closing movement of the door panel, and the gap between the vertical column and the door panel cannot be completely eliminated. Therefore, even when the convex portion as in Patent Document 1 is provided at the entrance / exit, the object may still be pulled in and the object may be caught on the end of the vertical column at the fully open position side. .

  This invention was made to solve the above problems, and when an object is drawn into the door pocket from the entrance / exit side, the occurrence of catching in the door pocket of the object can be suppressed, It is an object of the present invention to provide an elevator entrance / exit device that can easily pull out the object to the entrance / exit side.
