Embodiment approach 1

[0018] Hereinafter, the door apparatus of the elevator in embodiment of this invention is demonstrated using drawing.

[0019] The door device of the elevator according to Embodiment 1 of the present invention is installed on each floor where the car of the elevator stops, figure 1 It is a front view which shows the schematic structure of the door apparatus 1 of this elevator seen from the hoistway side. The door apparatus 1 includes two single-opening doors 2 , and a door hanger 3 including a hanger roller 4 is provided on the upper portion of each door 2 . In addition, a door rail 5 for suspending the door 2 is provided at the upper part of the entrance and exit opened and closed by the door apparatus 1 , and the hanger roller 4 of the door 2 is hung on the door rail 5 and rolls on the door rail 5, so that the door 2 is suspended. Open and close in the left-right direction in the figure. figure 1 The single-opening door 2 is shown in a closed state, and when the single-ope...

Abstract

The door apparatus of the elevator of the present invention is provided with a door slip prevention member for entering the lower part of the door stop side frame abutting against the door, and the door shoe is provided in the lower part of the single-opening door and is fitted into the sill of the sill. The groove is provided below the side frame of the door stop with an accommodating portion for accommodating the door disengagement preventing member when the door is closed. When the door closes the entrance and exit, the door detachment preventing member enters the accommodating portion of the lower part of the door stop side frame. Therefore, even if an external force is applied in a direction perpendicular to the opening and closing direction of the door to deflect the door and the door shoe is about to move upward, the door guard The disengagement member also touches the lower part of the door stop side frame located at the upper part of the accommodating part to restrict the upward movement of the door shoe, thereby preventing the door shoe from disengaging from the sill groove.

Description

technical field [0001] The invention relates to an elevator door device, in particular to a technology for preventing the door from falling out of the sill groove due to the external force applied to the door. Background technique [0002] A conventional elevator door is suspended from a door hanger that moves along a door guide rail provided above a doorway. In addition, a sill provided with a sill groove is arranged on the lower surface of the entrance and exit, and the door shoe provided at the lower end of the elevator door enters the sill groove and moves horizontally, so that when the door is opened and closed, the door shoe is The sill groove guides, and the lower part of the door does not swing in a direction perpendicular to the opening and closing direction of the door. In such an elevator door, if a force is applied in the direction of opening and closing the door only by the mechanism for opening and closing the door, the door shoe is guided by the sill groove, ...
