Description

  The present invention relates to an elevator hall device.

  Generally, the hall entrance / exit of the elevator is formed by a landing three-way frame standing on the landing and a floor surface of the landing, and is opened and closed by a landing door disposed on the hoistway side of the landing three-way frame. The above landing doors are always closed to ensure the safety of people on the landing when the elevator car is not stopped at the landing, and are installed in the car when the car stops at that landing. Open / close control is performed by the door drive device.

  Here, the landing door is generally provided with a hanger roller rotatably at the upper portion thereof, and the hanger roller rolls on a rail provided horizontally above the landing entrance, thereby opening and closing the landing door. The upper moving direction is guided. Therefore, a support member for supporting the rail and the like, a so-called hanger case is provided above the landing entrance.

  Since the hanger case needs to support the rail and the like, a predetermined size (for example, a width equal to or greater than the length of the rail) is required. In addition, since the landing door is supported by being always suspended from the rail, the weight of the landing door always acts, and it is also required to be able to withstand vibrations and shocks caused by opening and closing of the landing door and shaking during an earthquake. The

  As a conventional technology for an elevator landing apparatus equipped with such a hanger case, both ends of the hanger case are supported by support pillars erected from the sill of the landing (a cross member that supports the sill of the landing) and It has been proposed to install a horizontal bracket on a vertical member that is a part of a steel frame of the object, and to support the horizontal force acting on the hanger case on the horizontal bracket (see, for example, Patent Document 1). .

  In addition, as another conventional technique, a support column erected from the threshold of the landing is fixed using a guide rail in the hoistway, and the three-way frame and the hanger case are supported by the support column. The thing is also proposed (for example, refer patent document 2).
