Description

DETAILED DESCRIPTION OF THE INVENTION [School Field of the Invention] The present invention relates to an A-swordsman for man conveyors such as escalators and moving walkways.

[Technical background of the invention]

In recent years, the handrails of escalators, moving walkways, and other passenger conveyors have tended to be slimmer to save space, save materials, and improve design.

FIGS. 1 and 2 each show a conventional balustrade that has been slimmed down, and both of these balustrades are constructed so that the width of the balustrade frame is approximately the same as the width of the movable handrail.

First, to explain the parapet shown in Figure 1, 1.
is a hollow balustrade frame, and this balustrade frame l is
It'11 outside the steel core material 2 consisting of a horizontal upper plate part 2a and a side plate part 2b extending downward from the upper plate part 2a.
is covered with a surface cover 3 formed by bending a thin stainless steel plate into a groove shape. A handrail guide rail 5 is provided on this balustrade frame 1 via a rail support deck 4, and a movable handrail 7 is attached to this rail 5. The rail holder 6 is a roller provided in the deck 4 in order to move the movable handrail 7 smoothly, and the movable handrail 7 moves on this roller 6 while being guided by the rail 5. There is. On the other hand, reference numeral 8 denotes a balustrade panel made of a transparent plate, and the upper end of this balustrade panel 8 is inserted into the balustrade frame 1 and is attached to the balustrade via a cushioning rubber 10 by a panel presser 9 provided in the balustrade frame 1. The inner surface of the frame 1, that is, the side plate portion 2b of the core material 2
The pressure is fixed on the inner surface of the. 11 is a push bolt that presses the panel presser 9; this push bolt 11
is screwed through a bracket 12 attached to the core material 2 of the balustrade frame 1, and its tip extends so as to press the panel presser 9 from behind. I3 is an illumination lamp that illuminates the balustrade panel 8; 14 is an electric wire passed through the balustrade frame 1; the illumination lamp 13 is arranged in an opening on the lower surface of the balustrade frame 1;
Covered by 5.

In the case of a balustrade that is not equipped with illumination lamps 13, the opening on the lower surface of the balustrade frame 1 is covered by a cover plate 16. Further, the width of the parapet frame 1 is the same as that of the movable handrail 7.
Therefore, the parapet pile 8 is located closer to the center of the handrail than the edge of the movable handrail 70...1j.

In this balustrade, the width of the balustrade frame 1 is approximately the same as the width W of the movable handrail 7, and the balustrade pile 8 is arranged within the width W of the movable handrail 7, so the balustrade is viewed from above. When the handrail 7 folds back or when the handrail 7 folds back, when looking from the front, only the moving handrail 7 is visible, but the handrail frame 1 and the handrail pile 8 are hardly visible.
It is possible to give a good slim design to the +, and by reducing the width of the parapet frame I, it is also possible to save space and reduce the number of shrines. To explain +, this +! 4d (1) Remove the plastic plate 18 made of nylon or other material with a small friction coefficient on the surface of the key and handrail guide rail 170 f-1
By doing so, the rollers are unnecessary and the distance between the movable handrail 7 and the top surface of the balustrade frame 1 is reduced accordingly, and the other configuration is the same as that of the balustrade shown in FIG.

Note that the handrail guide rail I7 is fixed to the parapet frame 1 with bolts 19a and nuts 19b.

That is, the balustrade shown in FIG. 2 is similar to the balustrade shown in FIG. By doing this, the parapet can be slimmed down, and by reducing the distance between the movable handrail 7 and the top surface of the parapet frame 1, the thickness T of the parapet frame portion can be increased accordingly.
(T for a balustrade without illumination lamps 13) is made smaller than the balustrade shown in FIG. 1, and the balustrade non-common portion is made thinner, thereby improving the design of the side surface of the balustrade.

[Problems in the background art] However, in the conventional balustrade shown in FIGS. 1 and 2 above, the panel presser 9 that presses and fixes the upper end of the balustrade panel 8 against the inner surface of the balustrade frame 1 is attached behind the panel presser 9. Since it is designed to be pressed by the push bolt 11 from above, the installation space for the push bolt II and the push bolt 1 are limited.
In order to secure the working space for tightening the balustrade frame 1, the width of the balustrade frame 1 must be made large. It is possible to reduce the size only to approximately the same extent, and therefore, in the case of a balustrade in which the distance between the movable handrail 7 and the upper surface of the balustrade frame 1 is reduced as shown in FIG. 2, maintenance and inspection of the movable handrail 7 is Sometimes moving handrail 7
There was a problem in that the handrail guide rail 17 also had to be removed in order to remove it. This is shown in Figure 2, t
In the case of 1J, the width of the national land frame 1 is approximately the same as the width of the moving handrail 7, and the width of the moving handrail 7 and 41 and the handrail frame 1
Because the distance between the handrail 7 and the top surface is small, it is difficult to insert your hand or a tool between the handrail 7 and the top surface of the handrail frame 1.
This is because the opening edge %l (7a) cannot be removed from the handrail guide rail 17. Therefore, in order to remove the movable handrail 7, the movable handrail 7 must be removed from the handrail guide rail 17.
Therefore, maintenance and inspection of the moving handrail 7 required time and effort.

[Purpose of the invention]

The present invention was made in view of the above-mentioned circumstances, and its purpose is to make the width of the parapet frame even smaller than the conventional one, thereby further saving space and materials. In addition, even if the distance between the moving handrail and the top surface of the handrail frame is reduced, only the moving handrail can be removed without removing the handrail guide rail, making maintenance and inspection of the moving handrail easier. The purpose is to provide railings for man conveyors.

[Summary of the invention]

That is, in the present invention, panel retainer connecting bolts are provided protruding from the inner surface of the balustrade frame, and the connecting bolts are passed through the panel retainer, and a notch is provided at the upper end of the balustrade panel to provide relief for the bolts. The upper end of the balustrade panel is inserted between the inner surface of the balustrade frame and the panel retainer, and the upper end of the balustrade panel is pressed against the inner surface of the balustrade frame via the panel retainer by tightening the nut screwed into the connecting bolt. By fixing this, the push bolts installed behind the panel retainers in conventional balustrades are replaced, and the installation space for these push bolts is no longer required, making it possible to reduce the width of the balustrade frame.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 3 and 4 show a first embodiment of the present invention, and this embodiment is used for both 414[tl and 'ω] without illumination.

In Fig. 3, the frame shown in the figure is a 19"-1 frame, and this frame (i) has a horizontal ten-plate section 2a and a horizontal plate section 2a extending downward from one side of the upper plate section 2a. Straightforward 1lI
It has a hollow structure with a substantially rectangular cross section, in which the outside of the steel core material 2 consisting of the II plate portion 2b is covered with a surface cover made of a stainless steel ILQ plate. The surface cover is made of thin soil frame 1
A first surface cover 3a with a cross-sectional shape forming the upper surface and a side surface (the side surface on the side where the visitor rides), and a second surface cover J with a cross-sectional shape forming the other side surface and the lower surface of the balustrade frame 1.
It is divided into two parts on the left and right, consisting of b, and the first
The surface cover 3a is the top plate 2a and side plate 2b of the core material 2.
The second front cover 3b is attached to the cover receiver 20 attached to the lower surface of the upper plate 2a of the core material 2 with screws 2.
It is attached by 1. 22 is -ft1. of the parapet frame 1. This is a panel presser connecting bolt 22 that protrudes from the inner surface of the core material 2.
1 is provided horizontally so as to penetrate through the plate portion 2b. The connecting bolt 22 is loosely fitted through a panel presser 9 provided in the Rangan frame 1 facing the inner surface of the first rule board 2b of the core material 2.
A nut 23 for pressing the panel presser 9 from the back side is screwed onto the tip side of the panel holder 9 . On the other hand, 8 is a 1 board panel, IO
is a buffer rubber fitted to the upper end of the balustrade panel 8 to be inserted into the balustrade frame 1, and the upper end of the balustrade pile 8 is fitted with the panel retainer as shown in FIG. Notches 8a, which provide relief for the connecting bolts 22, are formed to correspond to the panel retainer connecting ports 22 provided at appropriate intervals in the length direction of the parapet, and the buffer rubber 10 is also provided with panel retainers. A notch 10 is formed as a relief for the connecting port 22.

The upper end of the balustrade panel 8 has the notch 8a.
By inserting the panel presser connection port 22 into the panel presser foot 9, the panel presser foot 9 and one inner side of the parapet pipe l are connected together!
, is inserted sufficiently deeply between the inner surface of the side plate portion 2b of the core material 2, and by tightening the nut 23, the panel presser 9
The pressing force is fixed to the side plate portion 2b of the core material 2 via the buffer rubber 10. Furthermore, the movable handrail 7 is provided with the lower surface of the handrail close to the upper surface of the balustrade frame, similar to the conventional balustrade shown in FIG. 2. Note that this moving handrail 7 and its guide rail 17 are the same as the conventional handrail shown in FIG. 2, so the same reference numerals are given in the figure and the explanation thereof will be omitted.

This balustrade is constructed by installing the core material 2 of the balustrade frame 1 over the entire length of the balustrade, then attaching the panel retainer connection port 22 to the side plate 2b of the core material 2, and attaching the first surface cover 3a to the outer surface of the core material 2. Handrail guide rail 1 on the top surface of the lever
7, attach the panel retainer 9 and the nut 23 to the connecting port 22, insert the upper end of the balustrade panel 8 into the balustrade frame 1, and tighten the nut 23 to secure the upper end of the balustrade panel to the balustrade. Fixed in frame l,
Finally, the second surface cover 3b is assembled by attaching it to the core member 2 via the cover receiver 20, and the movable handrail 7 is then attached to the handrail guide rail 17.

In this balustrade, a panel presser connection port 22 is provided protruding from the inner surface of the balustrade frame 1, and the panel presser connection port 22 is passed through the panel presser 9, and by tightening the nut 23, the panel presser connection port 22 is inserted through the panel presser 9. Since the upper end of the balustrade panel 8 is pressed and fixed to the inside surface of the balustrade frame, there is no need to install push bolts behind the panel holders like in conventional balustrades, and therefore four doors are required for the installation space of these push bolts. By reducing the width of the shadow frame 1, it is possible to further save space and save materials. According to this balustrade, in order to reduce the width of the balustrade frame 1, the outer side of the balustrade frame I (the second surface cover 3b
side) of the moving handrail 7 as shown in Figure 3.
The edge 7aJ can also be moved toward the center of the handrail, so that when the opening edge 7a of the movable handrail 7 is removed from the handrail guide rail 17, the parapet frame I will not become distorted. Even if the distance between the movable handrail 7 and the upper surface of the balustrade frame is reduced, only the movable handrail 7 can be removed without removing the handrail guide rail 17. Note that a panel presser connection port 22 is provided at the upper end of the parapet panel 8.
A notch 8a is provided as an escape for the railing panel 8, so the upper end of the parapet panel 8 is held between the panel retainers 9 and 41.Y.
Since it can be inserted sufficiently deeply between the balustrade frame and the inner surface of the balustrade frame, sufficient fixing strength of the upper end of the balustrade panel can be ensured. Moreover, in this balustrade, since the surface cover of the balustrade frame 10 is divided into the first surface cover 3a and the second surface cover 3b, the second surface cover 3
Before installing b, the outer side and lower surface of the frame I are open, so it is necessary to tighten the nut 23 that presses the nut 23 that presses the frame 7!9b that fixes the handrail guide rail 17 and the panel retainer 9. can be carried out easily in a wide space. In addition, in conventional balustrades, the surface cover of the balustrade frame is a groove-shaped integral piece, so if there is an error in the dimensions of the surface cover, a step may occur at the joint between the surface covers, especially when moving the handrail. The level difference on the side surface of the surface cover that is not hidden was conspicuous and spoiled its beauty. However, in the handrail of the above embodiment, the surface cover is divided into left and right sides, so each surface cover 3a and 3b is divided into two surface covers that are joined together. You can eliminate the difference in height by aligning and installing.

FIG. 5 shows a second embodiment of the present invention, in which reference numeral 11-0 is provided with an illumination lamp 13. Note that the balustrade of this embodiment has approximately the same configuration as the balustrade of the first actual case except that it is equipped with an illumination lamp 13 and a lamp cover 15, so the same reference numerals are given in the figures. The detailed explanation will be omitted. However, in this second embodiment, the illumination lamp 13 and the lamp cover 1
5, the second surface cover 3b of the 1.11φ1 frame I is shaped without a plate portion on the lower surface. In addition, in FIG. 5, 14 in the figure is the wiring passed through the frame 1 (÷1,000).The parapet of this second embodiment is also substantially the same as that of the first embodiment. from,
Effects similar to those of the first embodiment described above can be expected.

〔Effect of the invention〕

Since the present invention has the above-mentioned configuration, the width of the balustrade frame can be made smaller than that of the conventional one, and therefore space and materials can be further saved, and the width of the handrail and the balustrade can be further reduced. Even if the distance from the upper surface of the frame is reduced, only the movable handrail can be removed without removing the handrail guide rail, so inspection of the movable handrail can be carried out with good work efficiency.
