Description

[Detailed Description of the Invention] This invention relates to an improvement of an elevator landing device.

First, a conventional elevator landing device will be explained with reference to FIGS. 1 to 3.

In the figure, 1 is the elevator landing, 2 is the entrance/exit of this, 3 is the threshold forming the lower edge of the entrance/exit 2, and 3 is the entrance/exit of the elevator.
3b is the front edge of this, 3b is the dovetail groove 3c vertically installed on the front edge 3a, is the rear edge of the sill 3 facing the elevator hoistway 4, 5 is the three-sided frame, and 5a is the doorway 2.
The upper frame 5b of the three-sided frame 5 forming the upper edge is provided at the side edge of the three-sided frame 5 forming the side edge of the entrance 2 and having a groove-shaped cross section, and 5c is provided at the rear edge of the lower end of the side frame 5b. a notch 6, a wall of the landing 1 having an opening 6a; 7;
8 is a first fixture whose one side is fixed to the inside of the side frame 5b and the other side is placed horizontally at the lower end surface position of the side frame 5b; 8 is an L-shaped bolt with one side and engaged with the groove 3b; A second fixture 9 is fixed to the front edge 3a of the sill 3, and the other side faces the horizontal part of the first fixture 7, and 9 is the first and second fixtures 7, 8.
A fastener consisting of a bolt inserted through the bolt and a nut screwed into the bolt.

That is, the threshold 3 is provided at the edge of the hoistway 4 of the landing 1, and the three-sided frame 5 is arranged at the opening 6a of the wall 6. The lower end of the side frame 5b is configured to be fixed to the threshold 3 by a fastener 9 via first and second fixing members 7 and 8. This fastener 9 is the side frame 5b
Since the shaft is located inside the shaft, there is a problem in that the tightening work must be performed from the dangerous hoistway 4 side. Further, in order to operate the fastener 9, it may be necessary to scrape off the edge of the wall 6 even though the notch 5c is provided, which causes a problem that the side frame 5b requires a lot of trouble.

This invention solves the above-mentioned drawbacks and aims to provide an elevator landing device in which the three-sided frame can be fixed easily and safely.

An embodiment of this invention will be described below with reference to FIGS. 4 to 6.

In the figure, the same reference numerals as those in FIGS. 1 to 3 indicate corresponding parts, and 7 has one end fixed to the inner lower end of the side frame 5b by welding or the like and extended downward, and then bent horizontally to form the entrance/exit 2. The first fixture 8 is an L-shaped second fixture disposed within the width of the front edge 3 of the sill 3 through a bolt engaged with the groove 3b.
a and is arranged corresponding to the horizontal part of the first fixture 7, and the other side projects horizontally from the lower part of the one side and is arranged so as to overlap with the horizontal part of the first fixture 7. A fastener 9 is inserted through the first and second fixtures 7 and 8 and placed within the width of the entrance/exit 2.

That is, since the fastener 9 is disposed within the width of the entrance/exit 2, the fastener 9 can be easily and safely tightened by work from the landing 1. Also,
The cutout portion 5c of the side frame 5b is not required, making it possible to easily manufacture the side frame 5b, and eliminating the need for cutting off the opening 6a, allowing the three-sided frame 5 to be fixed efficiently. Note that after the side frame 5b is fixed to the sill 3 by the fasteners 9, the surface of the landing 1 is finished with mortar or the like, and the fasteners 9 and the like are buried therein.

As explained above, this invention consists of a first fixture that is fixed at one end to the lower part of the side frame of the three-sided frame and extends within the width of the downwardly extending entrance and exit, and a first fixture that is fixed to the front edge elevation of the sill and extends within the width of the entrance/exit. The three-sided frame is fixed to the sill by a first fixture and a second fixture fastened at a position below the upper surface of the sill. Thereby, an elevator landing device is realized in which the lower end of the three-sided frame can be safely and easily fixed from the landing, and the three-sided frame can be installed efficiently and at low cost.
