Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to long-head escalators, curved escalators, etc., and particularly curved escalators that require a wide main frame for strength and internal mechanism. This relates to the configuration of the parapet 9 entrance/exit of the passenger conveyor.

[Prior art]

First, by referring to Figures 1 to 3, for example,
This explains a conventional passenger conveyor consisting of a curved escalator shown in Publication No. 60. In the figure, (1) is a main frame which is annular in the horizontal projection plane, and (2) is a main frame along the length of this frame. Erected parapet +
(2a) is the balustrade board that forms the main part of the balustrade (2), (2b)
(2c) is a movable handrail that is movably engaged with the outer peripheral edge of the balustrade (2a), (2c) is an inner deck that forms the upper surface of the base of the balustrade (2) and is provided at the center of the main frame (11); (2d) )
is the outer deck facing the inner deck (2C).

In other words, the inner and outer decks (2C) (2d) are equipped with a parapet (2
) and is generally provided along the length of the
Manufactured from aluminum extruded shapes, stainless steel plates, etc. On the other hand, in a nine-curve escalator, when the steps move, a load is generated toward the center on the arc of the curve, and although one illustration is omitted, the friction loss of the entire drive mechanism is greater than that of a straight escalator. As the internal devices such as the main frame (1) become larger, the width of the main frame (1) becomes thicker. On the other hand, since the step width is the same as that of a straight escalator, the width dimensions of the inner and outer decks (2c) (2d) are wider than those of a straight escalator. Moreover, the position of the handrail (2) relative to the width of the steps must be the same as that of a straight escalator because passengers can grab the moving handrail (2b).

The width of the outer deck (2d) is abnormally wide compared to a straight escalator. However, the deck of a 9-curve escalator is curved and twisted to match the slope, so
There was a problem with the machining of the wide outer deck (2d), which required a lot of work to ensure accuracy and prevent machining scratches. In addition, because the outer deck (2d) is wide, the escalator lacks the slender and sleek appearance compared to a straight escalator, which impairs its aesthetic appearance.

[Summary of the Invention 1 This invention solves the drawbacks mentioned in 2.
A passenger conveyor that can be easily manufactured by forming a narrow outer deck with a finishing system of This is what we are trying to provide.

[Embodiments of the invention]

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

In the figure, the same reference numerals as in FIGS. 1 to 3 indicate corresponding parts.

(3) is an exterior plate that covers the side and bottom portions of the main frame (1);
4) is an edge deck in which the upper edge of the exterior plate (3) is bent horizontally to form the widthwise edge side of the main frame (1) at the base of the parapet plate (2a).

(2d) is an outer deck made of stainless steel that has a different appearance from the edge deck (4).
a) A parapet plate (2a) at the base of the balustrade (2a), which is provided between the lower ends and forms a raised step with respect to the edge deck (4).
a) Forms the outer edge side. (5) is the outer deck (2d
) edge deck (4) Decorative joint made of aluminum profile provided vertically on the edge of the edge, (6) is a step that moves completely between the parapets (2), (7) is the main frame (1) (8) is the floor plate of the entrance/exit (7), and the width direction of the main frame (1) is formed to a dimension corresponding to the inner distance between the edge decks (4) on both sides. has been done. (9) is the boarding entrance (7)
This is the floor surface of a building where a curved escalator is installed.

That is, the upper surface between the side surface of the main frame (1) and the parapet plate (2d) is constituted by the outer 111 deck (2d) and the edge deck (4). Therefore, the width of the outer deck (2d) can be narrowed, and even a curved and twisted shape can be easily processed, and a product with high precision and few processing scratches can be obtained. In addition, the side of the main frame (1) and the parapet board (
Since the area 2d) is divided into two parts along the length, a visually slender appearance and a light feel can be obtained. In addition, the exterior panels (3) and edge decks (4) are often constructed with a painted steel finish, plastered finish, etc., and these finishes must be done at the installation site in relation to the building where the curved escalator is installed. There is little need to ensure accuracy or improve workability, and construction is easy.

In addition, the floor plate (8) is configured such that the width direction of the main frame (1) is narrower than the width of the main frame (11), and the end of the main frame +11 at the 1 entrance (71) is placed below the floor surface (9). The floor plate (8) is smaller and can be produced at a lower cost, and it can also be made lighter, making installation and safety work easier.Furthermore, the floor plate (8)
The widthwise end of the main frame (1) is placed on the extension of the inner edge of the edge deck (4), so together with the outer deck (2d), the curved escalator as a whole has a visually slender appearance. A form that presents an aesthetic appearance can be obtained. In addition, the width direction dimension of the main frame (1) of the floorboard (8) can be made narrower than the outer distance between the outer decks (2d) on both sides, and even if it is narrowed in this way, an aesthetically pleasing form can be obtained. .

In addition, even if the appearance of the edge deck (4) is not the same as the exterior plate (3) in the embodiment shown in Fig. 4, if it has a similar appearance to the exterior plate (3), the embodiment shown in Fig. 4 may be implemented. The same effect as in the example can be obtained.

In addition, in the embodiment of FIG. 4, the steps (6) shown in FIG.
If the dimensions A and B from the width center to the sides of the exterior plate (3) are different, outer decks (2d) of the same width are placed on both sides, and the edge decks (4) on both sides are made with different widths. This results in a balustrade (2) that can be manufactured economically.

In addition, in the embodiment shown in Fig. 4, since the decorative joint (5) is not provided, the outer deck (2d) and the edge deck (4) are visually clearly separated, and the parapet (2) has a good appearance. can be obtained.

Furthermore, in the embodiment shown in Fig. 4, the outer 1111 deck (2d
), the edge deck (4) is provided at a lower position than the steps (61), so for those looking at the passenger two-curve escalator from the side, the main frame is visually narrow and narrow, giving it a smart appearance and aesthetics. A good parapet (21 is obtained.

〔Effect of the invention〕

As explained above, this invention provides an upper surface between the widthwise edge of the main frame and the lower end of the side board, and the widthwise edge side of the main frame has an appearance at least similar to the finish of the side surface of the main frame. The parapet board (1111 is formed by an outer deck with a different appearance from the edge deck, and the width direction of the main frame of the floor plate is a dimension corresponding to the inner mutual spacing of the edge decks on both sides, or This is shorter than the corresponding dimension.This allows for a narrower outer deck, making it easier to handle, and the floorboard is smaller, making it cheaper to manufacture and lighter, making it easier to maintain. In addition, the upper surface between the main frame side line and the balustrade board is outside (I'll
Divided along the length by the deck and edge deck, combined with the short floorboards in the width direction of the main frame, it looks like a Japanese-style room, Yl)1
The overall appearance of the passenger conveyor is aesthetically pleasing.
