Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a structure in which a fence body for preventing a human body from falling from a road surface is additionally provided on the outside of a transparent balustrade such as a passageway or an escalator of a building.

[0002]

2. Description of the Related Art Conventionally, as a side for arranging a fence-like structure on the outside of a transparent balustrade, Japanese Patent Laid-Open No. 58-1721 is used.
No. 85 or Design Registration No. 801133 is known.

[0003]

The above-mentioned conventional examples are all examples of escalator, but the former known example relates to a fence as a design expression.
On the other hand, the latter of the known examples is designed so that passengers do not fall from the escalator to the outside, and this point belongs to the same technical scope as the present invention, but the attachment structure of this fence body is from the lower position of the balustrade base. Since it is composed of a single thick plate in the vertical direction to a position that is considerably higher than the upper part of the balustrade, it is heavy and it is necessary to strengthen the body frame of the escalator in strength, requiring a special design for the fence body. From
There was a problem with standardization in production and cost, which prevented the spread of equipment recognized as effective for safety.

An object of the present invention is to provide a fence body attached to a transparent balustrade, which has a lighter structure of a fence body additionally provided on the outside of the transparent balustrade, standardizes the production of the main body frame and reduces the overall cost. Especially.

[0005]

To achieve the above object, the present invention is provided outside a transparent balustrade provided upright at a constant height from a road surface at a constant interval, and the transparent balustrade is provided. In a fence body that is installed side by side up to the position one step higher than the upper end of the balustrade of
A combination of a thin plate on the lower side in the vertical direction of the columns of the fence and a space between the columns and a thick plate on the upper side is a combination of these two layers to form a fence.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIG. In the figure with an escalator as an example, the transparent balustrade 3 that is fixed to the body frames 2 on both sides of the road surface 1 of the step where passengers pass and stands upright to prevent passengers from falling downstairs is the road surface 1 80 from the top
It is arranged at a height of 0 to 1,000 mm all over the longitudinal direction. And the balustrade plate 3 which comprises this transparent type balustrade 3
A fence body 4 made of a transparent material such as a glass plate or an acrylic resin plate is attached to a support column 5 fixed at a constant interval in the longitudinal direction of the main body frame 2 with a distance W from a (a glass panel or the like). Are arranged side by side up to a position higher than the balustrade board 3a. Here, the fence body 4 includes a thin plate 4A having a plate thickness ta of several mm on the lower side in the longitudinal direction between the columns 5 and columns (not shown), and a thick plate having a plate thickness tb of about 8 to 10 mm on the upper side. 4B, a two-layer type in which the relationship between the plate thicknesses of both is 4A <4B. Also, the thin plate 4A is the thin plate groove 5 of the support column 5.
At A, the thick plate 4B has an end portion attached to the thick plate groove 5B of the support column 5 to maintain strength, and the upper side of the support column 5 is in close contact to form a joint T. In the above configuration, the thickness difference (4B-4A) between the thick plate 4B and the thin plate 4A forming the fence body 4 is lighter than the conventional one, and the load on the main body frame 2 is reduced by this amount, which is standard. The main body frame 2 can be used and the cost can be reduced.

The structure for fixing the column 5 to the main body frame 2 is not limited to the one shown in the drawing, and the upper end of the thick plate 4B may be curved or V-shaped and separated from the transparent balustrade 3 outside. It belongs to the scope of the present invention. Further, the invention can be applied to not only the exemplified escalator but also a transparent balustrade for passages of buildings.

[0008]

According to the present invention described above, it is possible to reduce the weight of the fence body additionally provided on the transparent balustrade, thereby improving the productivity of the main frame and reducing the overall cost.
