Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a passenger conveyor such as an escalator and an electric road, and more particularly to an improvement in the structure of a landing plate laid at an entrance / exit of a passenger conveyor.

[0002]

2. Description of the Related Art FIGS.
And a landing plate for a conventional passenger conveyor disclosed in Japanese Utility Model Publication No. 61-43824.
In the figure, reference numeral 1 denotes an escalator which is installed so as to be inclined between an upper floor and a lower floor. As shown in FIGS. 3 and 5, the escalator 1 is guided by a guide rail in the inner longitudinal direction of the main frame. A plurality of steps 2 that move in a circular manner while being connected are arranged endlessly, and balustrades 3 are erected on both sides of the main frame. In this balustrade 3, there are endless steps that cyclically move in synchronization with the steps 2. A movable handrail 4 is wound around in a slidable manner. A machine room is formed at both ends of the main frame, and an entrance floor 5 serving as a foothold for passengers is provided above the opening of the machine room as shown in FIGS. 3 and 4.
Has been laid.

As shown in FIG. 4, the entrance / exit floor 5 supports a plurality of combs 6 that mesh with the tread surface of the moving step 2 to scoop up the objects on the tread surface, and support the plurality of combs 6 at the front end. Single landing plate 7 and this landing plate 7
And a plurality of manhole covers 8 located adjacently to the rear of the.

As shown in FIG. 2, the plane rectangular landing plate 7 is formed by cutting a thick steel plate into a substantially deformed convex shape in cross section, and a projecting portion at the front end is formed on the comb mounting seat surface 70. On this comb attachment seat surface 70,
A plurality of combs 6 are arranged in the longitudinal direction and screwed. Also,
An overhanging portion at the rear end is formed on the manhole cover support seat surface 71, and the front end of the manhole cover 8 immediately after is overlapped and supported on the manhole cover support seat surface 71. However, the comb attachment seat surface 70 and the manhole cover support seat surface 71 of the landing plate 7 are machined by a machine.

[0005]

The conventional landing plate of the passenger conveyor is constructed as described above, and the comb mounting seat surface 70 and the manhole cover support seat surface 71 are machined on the front and rear ends of the landing plate 7. Therefore, there is a problem in that it takes a long time for processing and that it is difficult to handle the heavy landing plate 7.

The present invention has been made in view of the above, and an object of the present invention is to provide a landing plate for a passenger conveyor which can shorten the processing time and improve the handleability.

[0007]

In the present invention, in order to achieve the above-mentioned object, a comb mounting seat surface made of L-shaped steel for supporting a comb is provided at a front end of a landing plate forming a floor of a passenger conveyor. The manhole cover support seat surface made of L-shaped steel for supporting the manhole cover is welded or screwed to the rear end of the landing plate.

[0008]

According to the present invention, since the comb mounting seat surface made of L-shaped steel and the manhole cover support seat surface are welded or screwed to the front and rear ends of the landing plate, it is necessary to machine the overhanging portion by a machine. Therefore, it is possible to reduce the processing time and the handling opportunities.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to an embodiment shown in FIG. 1. In the drawing, 7 is a landing plate made of thick steel plate, and this landing plate 7 is different from the conventional example as shown in FIG. Differently, it is configured to have a substantially pentagonal cross-section, and the front end of the comb mounting seat surface 70A made of L-shaped steel is screwed through a plurality of screws, and the rear end is made of L-shaped steel. The upright portion of the manhole cover support seat surface 71A is screwed through a plurality of screws. The comb attachment seat surface 70A and the manhole cover support seat surface 71A perform the same function as the conventional comb attachment seat surface 70 and the manhole cover support seat surface 71.

Other parts are the same as in the conventional example.

According to the above construction, since the comb attachment seat surface 70A made of L-shaped steel and the manhole cover support seat surface 71A are screwed to the front and rear ends of the landing plate 7 via screws, the projecting portion is machined. As a result, it is not necessary to perform a cutting process over a long period of time, and it is possible to significantly reduce the processing time and reduce the chances of handling the heavy landing plate 7.

In the above embodiment, the comb mounting seat surface 70A and the manhole cover supporting seat surface 71A are screwed to the front and rear ends of the landing plate 7, but the comb mounting seat surface 70 is shown.
It goes without saying that A and the manhole cover supporting seat surface 71A may be welded together by plug welding.

[0013]

As described above, according to the present invention, since the comb mounting seat surface made of L-shaped steel and the manhole cover support seat surface are screwed to the front and rear ends of the landing plate, the projecting portion can be machined. There is no particular need for cutting for a long time, and there is a special effect that the working time can be greatly shortened and the handling opportunities can be significantly reduced.
