Problems solved by technology

Therefore, the lifting preventing member is hidden by the floor structure, and the work of engaging the lifting preventing member to the floor frame becomes very complicated.
As a result, in the technology described in Patent Document 1, there is a danger that the tilting prevention member is not engaged with the floor frame, and the floor structure that is the floor cover is tilted.

[0036] 1-1. Structural Example of Passenger Conveyor

[0037] First, refer to Figure 1 to Figure 3 The structure of the passenger conveyance facility of 1st Embodiment (henceforth "this example") is demonstrated.

[0038] figure 1 It is a schematic configuration diagram showing a passenger conveying facility.

[0039] figure 1 The illustrated passenger conveyance facility 1 is an inclined type passenger conveyance facility installed on an upper floor 100A and a lower floor 100B of a building structure, that is, a so-called escalator. The passenger conveyor 1 includes a frame 2 installed in a building structure, an upper doorway floor 10A, a lower doorway floor 10B, an apron portion 4 , a plurality of steps 5 , and a railing portion 7 . In addition, in the passenger conveyance facility 1, an upper landing 3A connected to the upper floor floor 100A and a lower landing 3B connected to the lower floor floor 100B are formed.

[0040] The frame 2 is installed across the upper ...

no. 2 approach example

[0116] Next, refer to Figure 16 A passenger conveying facility according to a second embodiment will be described.

[0117] Figure 16 It is a cross-sectional view showing the fixing mechanism of the passenger conveyor of the second embodiment.

[0118] The passenger conveyor of the second embodiment differs from the passenger conveyor of the first embodiment in the structure of the fixing mechanism. Therefore, here, the fixing mechanism will be described, and the parts common to the fixing mechanism 60 of the passenger conveyor 1 according to the first embodiment will be assigned the same reference numerals and redundant descriptions will be omitted.

[0119] Such as Figure 16 As shown, the fixing mechanism 70 has the fixing member 53 , a cover-side fixing nut (not shown), and a frame-side fixing portion 75 . The fixing member 53 and the cover-side fixing nut are the same as the fixing member 53 and the cover-side fixing nut 47 of the first embodiment, and therefore des...

no. 3 approach example

[0127] Next, refer to Figure 17 A passenger conveying facility according to a third embodiment will be described.

[0128] Figure 17 It is a cross-sectional view showing the fixing mechanism of the passenger conveyor of the third embodiment.

[0129] The passenger conveyor of the third embodiment differs from the passenger conveyor of the first embodiment in the structure of the fixing mechanism. Therefore, here, the fixing mechanism will be described, and the parts common to the fixing mechanism 60 of the passenger conveyor 1 according to the first embodiment will be assigned the same reference numerals and redundant descriptions will be omitted.

[0130] Such as Figure 17 As shown, in the fixing mechanism of the third embodiment, no frame-side fixing nut is provided. Frame side threaded holes 26c are formed in the bottom plate portion 26B of the third frame member 22 with respect to the frame side fixing nuts. A female thread that is screwed into the second threaded ...

Abstract

Provided is a passenger conveying device capable of reliably preventing the lifting of a floor cover. Passenger conveyors have frames, steps, and access floors. The entrance floor includes a floor frame (14) fixed to the frame and floor covers (12, 13) provided on the floor frames (21A, 21B). Frame-side stoppers (31) are provided at both end portions of the floor frames (21A, 21B) in the width direction perpendicular to the length direction. In addition, cover-side stoppers (46) engaged with the frame-side stoppers (31) are provided at both ends in the width direction of the floor covers (12, 13).

Description

technical field [0001] The present invention relates to passenger transfer equipment. Background technique [0002] The passenger conveying facility includes a frame installed in a building structure, and a plurality of ring-shaped steps that are installed in the frame and connected in a circular motion. An endless chain is connected to a plurality of steps, and the plurality of steps are cyclically moved by being rotationally driven by the chain. In addition, an entrance / exit floor covering the upper part of the machine room is provided at both end portions of the frame in the passenger conveyor. [0003] As a conventional entrance floor, there exists the entrance floor as described in patent document 1, for example. Patent Document 1 describes a technique related to a passenger conveyance facility that includes a frame installed in a building structure, a pair of entrance and exit floors provided at both ends in the longitudinal direction of the frame, and an entrance an...
