Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a passenger conveyor comb plate.

[0002]

2. Description of the Related Art FIGS.
FIG. 1 shows a conventional combboard of a passenger conveyor disclosed in Japanese Patent Publication No. 77, etc., in which 1 is a passenger conveyor, and the main frame of the passenger conveyor 1 is circulated in a longitudinal direction as shown in FIG. A plurality of moving steps 2 are arranged in an endless manner, and balustrades 3 are erected on both sides of the main frame. The balustrade 3 has an endless shape that circulates in synchronization with the steps 2. Moving handrail 4
Is slidably wound. In addition, an entrance / exit is provided at both ends of the main frame of the passenger conveyor 1, and an entrance / exit floor 5 serving as a foothold for passengers is laid above the opening of the entrance / exit.

As shown in FIG. 3, the balustrade 3 comprises a platform 30 placed on both sides of the main frame, and an inner surface of the platform 30.
A skirt guard 31 facing the side part of the through a gap,
It is provided with a comb skirt 32 that constitutes the inner surface of the platform 30 and is located on both sides of the entrance / exit floor 5, and a panel 33 that stands on the platform 30 and guides the moving handrail 4 to a moving handrail guide at the top (not shown). ing.

As shown in FIGS. 3 to 5, the entrance / exit floor 5 has a comb plate 50, a comb plate back plate 51 attached to the lower surface of the front end of the comb plate 50, and the comb plate back plate 5.
1 is provided with a comb 52 which is screwed onto the upper surface of the recessed front end through two countersunk screws 53 and meshes with the cleat of the tread surface of the step 2, and the combs 52 are arranged in the longitudinal direction of the comb plate back plate 51. They are installed side by side. The combs 52A located on both sides of the plurality of combs 52 are screwed so as to sneak into the lower part of the comb skirt 32, as shown in FIG.

Therefore, when the comb teeth of the combs 52A located on both sides of the plurality of combs 52 are damaged and must be replaced, the comb skirt 32 must be removed from the base 30.

[0006]

Since the conventional comb plate of the passenger conveyor is constructed as described above and a part of the comb 52A is screwed into the lower part of the comb skirt 32 so as to sneak into the comb plate, the comb which has sunk into the comb plate is not provided. To replace the 52A, you have to remove the comb skirt 32 from the stand 30 each time.
Workability was poor.

The present invention has been made in view of the above, and an object thereof is to provide a comb plate for a passenger conveyor in which combs located on both sides can be replaced without removing the comb skirt.

[0008]

In order to achieve the above-mentioned object, the present invention has a comb plate laid at an entrance / exit of a main frame of a passenger conveyor and a comb plate back plate attached to a front end of the comb plate. And a plurality of combs that are screwed side by side on the comb plate back plate and mesh with the cleats of the treads of the steps, the balustrades that are erected on both sides of the main frame, and the lower inner surface of the balustrade that constitutes the comb plate back plate. A comb skirt adjacent to the combs located on both sides is provided. Moreover, a gap is formed between the combs located on both sides of the comb plate back plate and the comb skirt, and the width of the comb plate back plate is set to the width between the comb skirts. It is characterized by making it wider than.

[0009]

According to the present invention, when the combs located on both sides of the back plate of the comb plate are replaced, it is not necessary to remove the comb skirt from the balustrade base, so that the workability can be improved.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to an embodiment shown in FIGS. 1 and 2. In the drawings, reference numeral 50 denotes a comb plate, and the comb plate 5
As shown in FIG. 2, the lower surface of the front end of 0 is a comb plate back plate 5
1 is attached, and a plurality of combs 52 that mesh with the cleats of the tread surface of the step 2 are screwed side by side via two countersunk screws 53 on the upper surface of the recessed front end of the comb plate back plate 51.

As shown by the arrow in FIG. 1, the width 51a of the comb plate back plate 51 is the width 3 between the comb skirts 32.
It is wider than 2a. Also, the back plate of the com skirt 5
Side of comb 52A located on both sides of 1 and comb skirt 32
As shown by the arrow in FIG. 1, a slight gap 6 is formed between and.

Other parts are the same as in the conventional example.

According to the above construction, unlike the conventional example, since the slight gap 6 is formed between the comb skirt 32 and the comb 52A, it is necessary to remove the comb skirt 32 from the base 30 when replacing the comb plate 52A. There is no need, and the workability of replacement work can be greatly improved. Since the width 51a of the comb plate back plate 51 is made wider than the width 32a between the comb skirts 32, 32, as shown in FIGS. 1 and 2, a gap 7 between the comb plate back plate 51 and the tread surface of the step 2 is formed.
(See FIG. 2) can be secured over the width 31a between the comb skirts 32, and it is possible to reliably prevent the safety of the comb plate portion from being lowered due to the formation of the gap 6.

[0014]

As described above, according to the present invention, a gap is formed between the comb skirts located on both sides of the comb plate back plate and the comb skirt, and the width of the comb plate back plate is smaller than the width between the comb skirts. Since it is also widened, there is a special effect that the combs located on the both sides can be replaced easily and quickly.
Further, there is a particular effect that it is possible to reliably prevent the safety of the comb plate portion from being lowered due to the formation of the gap.
