1 to 4 show one embodiment of a movable roof for working on an outdoor escalator according to the present invention. Omitted. Reference numeral 5 designates two side fittings 5a attached to both sides of the moving handrail 2 and a plurality of connecting bolts 5b for connecting the side fittings 5a, and is configured to be easily detachable. It is a fixing metal attached to each.

Reference numerals 6a and 6b denote pillars which are connected to each of the fixing brackets 5 in a socket manner and are detachably erected. Reference numeral 7 denotes an upper end between the left and right pillars 6a, and both ends of the upper end of the pillar 6a. A beam member (hereinafter, referred to as a "first beam member"), which is connected to the portion in a socket type and is detachably connected to form a rectangular frame extending between the left and right moving handrails 2 together with the left and right columns 6a, and 8 is a column. A socket member attached to the upper end of the first beam member 6a and the end of the first beam member 7 to detachably connect the column 6a and the first beam member 7.

Reference numeral 9 denotes a beam member (hereinafter referred to as a “beam member”), which is bridged over both ends between the first beam members 7 and forms a rectangular frame that straddles the moving handrail 2 in the longitudinal direction together with the columns 6a and 6b. A second beam member). The second beam member 9 has an intermediate portion 9a that can freely follow the shapes of the upper bent portion 2a, the lower bent portion 2b, and the straight portion 2c of the moving handrail 2.
Are configured to be deformable.

Numerals 10 are attached to both ends of the second beam member 9, respectively, so that the second beam member 9 slides along the end of the second beam member 9 so that the second beam member 9 follows the installation interval between the columns 6a and 6b. The slide member 11 to be wound is wound around the first beam member 7 and the slide member 10, and a rubber band for detachably connecting the first beam member 7 and the second beam member 9 via the slide member 10, 12 A sheet member that is detachably installed on a roof frame formed in a rectangular shape from the first beam member 7 and the second beam member 9 and that constitutes a roof surface that blocks direct sunlight and wind and rain; It is attached to each corner of the member 12 and is wound around the upper ends of the columns 6a and 6b, respectively, to fix the respective corners of the sheet member 12 to the columns 6a and 6b, respectively. Is a binding straps.

Next, a method of assembling the movable roof for outdoor escalator work according to the present invention will be described step by step. First, the fixing bracket 5 is attached to each of the left and right handrails 2 at predetermined intervals in the moving direction of the left / right moving bracket 2. Next, the columns 6a and 6b are erected on each of the fixing brackets 5, and the first beam member 7 is bridged between the left and right columns 6a and the upper end between the columns 6b, respectively. And are connected to the columns 6a and 6b.

Next, the second beam member 9 is bridged between both ends of the first beam member 7, and slide members 10 are attached to both ends of the second beam member 9, respectively. By fixing to the first beam member 7 by the rubber band 11, both ends of the second beam member 9 are
Connect to

Next, a sheet member 12 is placed on a roof frame composed of the first beam member 7 and the second beam member 9, and each corner of the sheet member 12 is fastened to the upper ends of the columns 6a and 6b. It is fixed by the string 13.

With the above configuration, the movable roof for the outdoor escalator work can be easily installed and removed on the moving handrail 2 of the escalator, and can be maintained by pushing on the left and right moving handrail 2 and sliding in the moving direction of the moving handrail 2. It is possible to easily move to the inspection point, so that the maintenance and inspection work can be performed very efficiently by blocking direct sunlight and wind and rain at the maintenance and inspection point.

The center 9a of the second beam member 9 is formed to be deformable, and both ends of the second beam member 9 are
0, and is connected to the first beam member 7 by a rubber band 11, and further, each corner of the sheet member 12 is
The movable roof can smoothly move the upper curved portion 2a, the lower curved portion 2b, and the straight portion 2c of the moving handrail 2 because the movable roof is connected to the upper end portions of the movable handrails 2 by a stretchable lace 13 (see FIG. 4). .

It is to be noted that three or more fixing brackets 5 are attached to the moving handrail 2 in the moving direction, and columns 6a and 6b are erected on each of the fixing brackets 5, and between the columns 6a and between the columns 6a and 6b. First beam member 7 and second beam member 9 respectively
And the sheet member 12 is installed on the roof frame composed of the first beam member 7 and the second beam member 9 so that the roof area is elongated in the moving direction of the moving handrail 2 according to the work area. Can be expanded.

[0019]

According to the first aspect of the present invention, a movable roof for outdoor escalator work according to the first aspect of the present invention is provided with a plurality of movable escalator left and right movable handrails which are detachably erected and move in the moving direction of the movable handrails. A column and a plurality of beam members that are bridged between the columns and form a gate-shaped frame together with the columns, and are installed on a roof frame composed of the beam members,
Since it is configured with a sheet member that constitutes the roof surface, it can be freely moved in the moving direction of the moving handrail to cover the maintenance and inspection location and block direct sunlight and wind and rain. The maintenance and inspection work can be performed without any problem.

In the movable roof for outdoor escalator work according to the second aspect of the present invention, the central portion of the beam member is deformed by following the upper curved portion, the lower curved portion, and the straight portion of the moving handrail. There is an effect that the upper curved portion, the lower curved portion, and the straight portion of the moving handrail can be smoothly moved.
