Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator door device, and more particularly, to an improvement in fixing means for a hanger case mounting metal and a sill receiving metal immediately above the mounting metal. .

[Prior Art] FIG. 4 is a vertical sectional view of a hoistway portion showing a conventional elevator door device. In the figure, (1) is an entrance / exit of each floor communicating with the hoistway (A), and (2). Is a door provided in front of each of these doorways, (3) is a hanger case for accommodating the suspension traveling member (4) of each door, (5) is a mounting metal for these hanger cases, and (6) is a layer directly above it. (8) is a sill fixing bracket for the door (2), and (8) is a sill fixing bracket for supporting the receiving so that the doorways (upper and lower tiers) of the upper and lower tiers are positioned so as to be located right above the hanger case attachment (5). 1) Polymerization is fixed to the back surface of the spacing wall (9) between (1) as in the case of the mounting metal (5). FIG. 5 is a partially enlarged sectional view of FIG. 4, in which (5a) is an anchor bolt for fixing the mounting metal (5), (8a) is an anchor bolt for fixing the sill fixing bracket (8), (6a) is a mounting bolt for the above-mentioned receiving plate (6). FIG. 6 is a view of FIG. 5 viewed from the direction of the arrow shown in the figure. The sill fixing bracket (8) is formed in a U-shaped trough shape, and the receiving plates (6) are respectively provided on both outer side surfaces thereof. It is fixed by superposition, and on the back side of the spacing wall (9) as shown in the figure so that the distance (D) between the two outer side receivers is the same as the distance between the left and right side surfaces of the entrance (1). They are arranged side by side in a facing state. Further, (5b) in the figure is an elongated hole for adjusting the mounting height of the mounting plate (5).

[Problems to be Solved by the Invention] As described above, in the conventional elevator door device, the mounting metal (5) and the sill fixing bracket are provided between the hanger case (3) and the metal receiver (6) of the sill (7). Since (8) and (8) are fixed vertically with anchor bolts (5a) and (8a), respectively, when the height of the floor is low and the height of the spacing wall (9) is small, Not only does the upper end of 5) interfere with the lower end of the sill fixing bracket (8), but there is also a problem that the work of driving each anchor bolt is troublesome.

An object of the present invention is to use a threshold fixing bracket in common for fixing a mounting metal of a hanger case so as to solve the above problems.

[Means for Solving the Problem] In the case of the present invention, the mounting metal of the hanger case is superposed and fixed to the lower end portion of the threshold fixing bracket.

[Operation] In the case of the present invention, the lower half of the threshold fixing bracket is used for adjusting and fixing the mounting position of the mounting metal of the hanger case.

[Embodiment] An embodiment of the present invention will be described below. That is, in FIG. 1 to FIG. 3, the same or corresponding portions as those in FIG. 5 are designated by the same reference numerals and their duplicate description will be omitted. However, in the case of the present invention, the mounting metal of the hanger case (3) is attached. The upper end of (5) is characterized in that it is polymerized and fixed to the outer surface of the lower end of the sill fixing bracket (8) with a connecting bolt (10). A long hole (5c) on the side of the mounting metal (5) for adjusting the mounting position of the and a long hole (8a) on the side of the sill fixing bracket (8) are formed, and the connecting bolt ( In 10), the attachment metal (5) is connected to the upper and lower sides and the front and rear sides so as to be adjustable. That is, the mounting metal (5) of the hanger case (3) is polymerized and fixed to the lower half of the sill fixing bracket (8) so that the fixing anchor bolts are not required unlike the conventional ones.

EFFECTS OF THE INVENTION Since the elevator door device of the present invention is configured as described above, each of the upper and lower hierarchies changes due to a change in the degree of intersection between the lower end of the sill fixing bracket and the upper end of the hanger case attachment metal. Not only can the size of the spacing wall between the entrances and exits in the vertical direction at that time be easily accommodated, but there is no need to embed the anchor bolts for fixing the attachment metal.

[Brief description of drawings]

FIG. 1 is a vertical sectional view of a hoistway portion showing an essential part of an elevator door device of the present invention, FIG. 2 is a view of FIG. 1 viewed in the direction of the arrow, and FIG. 3 is of the present invention. FIG. 4 is a perspective view of each component used, FIG. 4 is a vertical cross-sectional view of a hoistway portion showing the entire conventional elevator door device, FIG. 5 is an enlarged cross-sectional view of an essential part thereof, and FIG. 6 is FIG. FIG. 4 is a view of the above-mentioned in the direction of the arrow. In the figure, (1) is an entrance / exit, (2) is a door, (3) is a hanger case, (4) is a suspended traveling member, (5) is a mounting gold, (6) is a receiving gold, and (7) is a threshold. , (8) sill fixing bracket, (8a) anchor bolt, (9) spacing wall,
