Description

[Detailed description of the invention] Purpose of invention] (Industrial application field) The present invention relates to a transparent panel balustrade for an escalator.

(Prior Art) Recently, in an escalator using a transparent panel, a deck board provided above the transparent panel in order to simplify the structure of the handrail has been constructed as shown in FIG. That is, a guide rail 2 that engages with the inside of the handrail 1 to guide the movement of the handrail 1, and a frame 4 having an inverted U-shaped cross section and an opening for press-fitting and fixing to the upper end of the transparent panel 3.
These two members are constructed integrally by welding using thin steel plates. Further, a presser rubber 5 is interposed between the transparent panel 3 and the frame 4 to absorb dimensional errors due to welding deformation between the frame 4 and the panel.
Ensures fixation.

Further, since the frame 4 is held against the transparent panel 3 only by the frictional force generated between the presser rubber 5 and the frame 4, it is easy to come off. Therefore, in order to prevent the panel from coming off, as shown in FIG. Another method has also been adopted in which the tip of the folded portion engages with a stepped portion A provided on the presser rubber 7.

(Problems to be Solved by the Invention) However, the conventional structure as described above has the following disadvantages. First, the guide rail 2 and the frame 4 or 6 are molded separately, cut to the required length, and then welded together, which takes time and increases costs.

Further, since the panel and frame are fixed together by the pinching force (frictional force) generated by press-fitting, precision of the dimension W of the opening of the frame is required, which is difficult to manage. That is, if the opening width is narrow, it is difficult to press fit the upper end of the panel, and if the opening width is wide, an appropriate holding force cannot be obtained. In particular, it is particularly difficult to control dimensions at the upper and lower curved portions of escalators because the opening width changes due to bending. Furthermore, there is a problem in that the straight portions are also deformed due to contact with the guide rail, resulting in changes in dimensions.

[Structure of the Invention] (Means for Solving the Problems) The guide rail and the frame were welded together to form a deck board, but the welding was stopped and only the frame was glued to the upper end of the transparent panel, and then the frame was glued on top of it. The deck board is constructed by fixing the guide rail with screws.

(Function) Since the frame and guide rail are fixed by screw tightening, uniform tightening is possible, and the amount of deformation of both the guide rail and frame is extremely small.

(Example) This will be explained based on FIGS. 1 and 2.

The frame 9 is formed into an inverted U shape using a thin steel plate. This frame 9 is fitted into the transparent panel 3 and bonded with adhesive A. Separately, a guide rail 8 made of a thin steel plate and having a flat cross-sectional shape matching the inner surface shape of the moving handrail 1 is fastened onto this frame with screws 10. In this case, holes and screws are provided in the frame 9 and guide rail 8 to be screwed, and a recess 11 is provided on the transparent panel side to allow the projection of the screws to escape.

[Effects of the Invention] Since the present invention has such a configuration, there is no need to weld the guide rail and the frame into one body, and there is no need for presser rubber, resulting in lower manufacturing costs.

In addition, the deformation of both the frame and the guide rail is small, which improves the accuracy of the deck board, so the guide of the moving handrail becomes smoother, and the moving efficiency and lifespan of the moving handrail are increased.

Furthermore, dimensional control of the opening in the frame, which has conventionally been a problem when press-fitting frames and panels, does not require strict dimensional accuracy due to small deformation and the use of adhesive.

Furthermore, assembly is facilitated because it is only necessary to fix the frame to the transparent panel with adhesive and fasten the guide rail thereto with adjustment washers and screws.

In this way, a parapet with a simple structure and easy assembly can be provided.
