Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement of a handrail support and guide device for a passenger conveyor that supports and guides a handrail using a parapet panel.

[Prior art]

As shown in FIGS. 1 and 2, the conventional handrail support and guide device has a notch 1a at the upper end of a handrail panel 1 made of transparent tempered glass, etc., and a notch 2a provided in a U-shaped cushioning material 2. Cover the upper end of the balustrade panel 1 with the cushioning material 2 so that the notch 1a of the balustrade panel 1 faces, and then
Fit the guide frame 3 having the groove 3a, insert the screw 4 into the notches 1a and 2a, and tighten the nut 5.
After the balustrade panel 1 and the guide frame 3 are securely fastened together, the guide 6 is fitted into the groove 3b provided above the guide frame 3.

[Problem that the invention seeks to solve]

In such a conventional handrail support and guide device, notches for screwing must be provided at the upper end of the balustrade panel, and there is a risk that the balustrade panel will be damaged due to over-tightening of the screws, resulting in extremely poor assembly efficiency. In addition, handrail 7 with limited space
In order to construct a handrail support and guide device with excellent design by providing the guide frame 3 within the inner periphery of the handrail, extremely small screws must be used.
It is also difficult to handle.

For this reason, as shown in FIG. 3, the balustrade panel has a frame 12 made of a thin plate of stainless steel or the like formed to have grooves with openings facing upward and downward, respectively, and grooves having openings facing downward. The upper edge of the balustrade panel 11 is loosely inserted through the cushioning material 13, and a short elastic member 14 having a cross section with one side open and the middle part concave inward is fitted onto the upper edge of the balustrade panel 11. Frame 12 and elastic member 1
The applicant has recently proposed a simple handrail support and guide device that integrates four parts.

However, in such a device, due to molding errors of the frame 12 and manufacturing errors of the balustrade panel 11,
Even if the elastic member 14 with a strong spring is used, there are cases where it is difficult to reliably integrate the frame 12 and the balustrade panel 11.

The present invention has been made in view of the above points, and an object of the present invention is to provide a handrail support and guide device that is easy to assemble and can reliably integrate a frame and a handrail panel.

[Means for solving problems]

The present invention is provided with two frames formed to have a groove with an opening facing upward, each having flanges at different levels at the left and right ends, and the lower flange ends of the frames are spaced apart from each other. The lower flanges are placed over the upper edge of the balustrade panel via a cushioning material so as to face each other, and elastic members are fitted into the grooves of the frame located on the left and right sides of the balustrade panel. This is intended to be integrated with the frame.

[Effect]

With the above configuration, even if there is a manufacturing error or molding error between the balustrade panel and the frame, the distance between the frames will be appropriately reduced when the elastic member is inserted, so that the balustrade panel and frame can be easily and reliably integrated. It can be a structure.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 4 is a cross-sectional view of a handrail support and guide device showing an embodiment of the present invention, in which the same reference numerals as in FIG. 3 indicate the same parts.
Reference numeral 2 denotes a frame that separately covers the left and right upper edges of the balustrade panel 11 via a cushioning material 13, and is formed to have a groove with an opening facing upward, and is provided with flanges at different levels at the left and right ends, respectively. This frame has a shape similar to that of a conventional frame 12 divided at the center. The attached frames 121 and 122 have one ends of the lower flanges 121a and 122a facing each other with a distance a between them, and when the elastic member 14 is fitted onto the frames 121 and 122, the balustrade panel 11 is fabricated. Even if there is an error, a molding error of the frames 121, 122, or a dimensional error of the cushioning material 13, it can be absorbed at the part of the gap a and the frames 121, 122 and the parapet panel 11 can be reliably integrated. It's summery. 150 is a guide rail made of synthetic resin etc. that directly supports and guides the handrail 7;
21, 122 upper flanges 121b, 122b
Insert and install in sequence. Reference numeral 170 is a gap for reducing the sliding contact resistance between the handrail 7 and the guide rail 150, which rotate in synchronization with a step (not shown).

〔Effect of the invention〕

With the configuration described above, there is no need to provide a notch for screwing at the upper end of the balustrade panel, and even if there is a manufacturing error or molding error in the balustrade panel, frame, etc., the frames will not fit together when the elastic member is inserted. By reducing the gap appropriately, the parapet panel and frame can be easily and reliably integrated into an integrated structure, so the cushioning material does not protrude downward and impair the design.Furthermore, the handrail can be directly supported and guided. Since the guide rails to be mounted can be successively inserted into the upper flanges of the frame, it is possible to obtain a handrail support and guide device that is extremely easy and compact.

Further, with the support and guide device according to the present invention, it is extremely easy to change the size of the frame and make the frame protrude from the lower surface of the handrail as shown in FIG. 5, thereby changing the design.
