Embodiment approach 1

[0012] Fig. 1 is a front view of main parts showing an elevator doorway device according to Embodiment 1 of the present invention. And FIG. 2 is a sectional view along line II-II in FIG. 1 . In addition, FIG. 1 is a front view of main parts showing the doorway device of an elevator when the hall side is seen from the hoistway side. In the drawing, a floor board 2 as a decorative board is provided on the floor of the boarding point 1 . And between the landing 1 and the hoistway 3, a landing entrance 4 ( FIG. 2 ) connecting the landing 1 and the hoistway 3 is provided.

[0013] A support member 5 extending from the hall 1 to the hoistway 3 is fixed to the floor of the hall 1 with anchor bolts. A doorway floor member 6 provided under the landing doorway 4 is fixed to the support member 5 . The entrance / exit floor member 6 is arranged at the end of the floor plate 2 . Furthermore, the doorway floor member 6 extends in the width direction of the hall doorway 4 . The rigidity o...

Embodiment approach 2

[0032] Fig. 3 is a sectional view of main parts of an elevator doorway device according to Embodiment 2 of the present invention. In the drawing, a stopper 31 is fixed to the upper surface of the landing threshold 8 by bolts 32 , and the stopper 31 is used to limit the displacement of the connection member 13 in the direction away from the entrance floor member 6 to the side of the hoistway 3 . By restricting the amount of displacement of the connecting member 13 by the stopper 13 , it is possible to prevent the insertion body 12 from coming out of the groove portion 10 . In this example, the inclination of the door foot 11 relative to the landing threshold 8 is limited by the stopper 31 so that the inclination is smaller than the inclination of the insertion body 12 disengaging from the groove 10 .

[0033] The stopper 31 has a fixing portion 33 horizontally fixed to the landing threshold 8 , and an abutting portion 34 extending upward from an end portion of the fixing portio...

Abstract

A doorway device for an elevator, in which a doorway floor member is provided at the lower part of the doorway of the elevator, the doorway floor member is extended in a width direction of the doorway of the elevator, elevator doors for opening and closing the doorway are arranged above the doorway floor member, a doorsill having a groove extended in the width direction of the doorway is placed below the doorway floor member, door legs are provided at the lower ends of the elevator doors, and the door legs have insertion bodies inserted in the groove and have connection members having a shape that straddles the doorway floor member and connecting the elevator doors and the insertion bodies.

Description

technical field [0001] The invention relates to an entrance and exit device of an elevator, which opens and closes the entrance and exit of an elevator connecting a car and a landing through an elevator door. Background technique [0002] In a conventional doorway device for an elevator, a sill frame for guiding a door is arranged below the floor surface in order to improve design. A bottom edge extending vertically downward avoiding the floor is fixed on the lower part of the door. A lower door guide movable in the moving direction of the door is disposed in the slit of the door sill frame. A guide retaining bracket extending horizontally towards the bottom edge is fixed on the lower door guide. The guide holding bracket is connected to the bottom edge below the floor surface (see Patent Document 1). [0003] Patent Document 1: Japanese Patent Publication No. 3061751 [0004] However, in this conventional elevator entrance and exit device, the bottom edge fixed on the d...
