Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an escalator 1 or a passenger conveyor on an electric road, etc., and is particularly applicable to increasing the bonding strength between a glass panel of a handrail and a guide frame for guiding a handrail. Regarding preferred balustrades.

[Foreground of invention]

The main structure of a conventional passenger conveyor, as shown in Fig. 3, is a step 1 that is connected in an endless manner to transport passengers, a moving body such as a handrail 2 that rotates in synchronization with the step 1, and
The parapet 39 is composed of a fixed body such as the body frame 4, and is mounted under the floor of the building.

The handrail 3 is connected to the handrail 2 as shown in Figure 4.
In order to guide the glass panel 5, a guide frame 6, a guide 7, a fixing bolt 8, etc. are provided at the upper end portion of the glass panel 5.

The structure of FIG. 3 and FIG.
The details are shown in FIG. 5. ``While the upper end of the glass panel 5 is protected by a protective gasket 5a, a guide frame 6 having an inverted U-shaped groove 6A is mounted thereon. Furthermore, a fixing bolt 8. Pressure plate 8a.

A screw plate 8b, a hollow cylinder 8c, etc. are arranged. Note that this notch 5b is appropriately arranged in the longitudinal direction of the glass panel 5a, and the fixing bolt 8 is inserted into the clamping plate 8a and the hole 6 as shown by arrow A.
b, hollow strip 8o (actually passes through the notch 5b)
By inserting it into the screw plate 8b and screwing it into the screw plate 8b, the thickness W of the upper end of the glass panel 5 is firmly gripped from the direction of arrows B and C by the groove 6A. Furthermore, after the glass panel 5 and the guide frame 6 are fastened as shown in FIG. 5, the guide 7 is pressed from both sides in the arrow and E directions to engage the convex portions 7a and 7b with the grooves 6a and 60.

This balustrade structure accommodates the handrail guide members such as the guide frame 6 within the thickness h of the handrail 2, and the area of the glass panel 5 is large, attracting attention as a highly transparent passenger conveyor. There is. However, as shown in FIG. 5, the parapet 3 has a large number of small parts, making assembly work complicated.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a balustrade structure with improved reliability in which an adhesive is used to join the glass panel of the balustrade and a guide frame for guiding a handrail.

[Summary of the invention]

The present invention has a structure in which it is possible to visually check whether the adhesive is reliably injected into the adhesive layer of the glass panel and the guide frame that are bonded together with the adhesive, thereby increasing the reliability of the adhesive force.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described based on the drawings.

1 and 2, there are no protective gaskets 5a, notches 5b, fixing bolts 8, etc. on the upper end of the glass panel 9 of the present invention, which corresponds to the conventional glass panel 5; A guide frame 10 having an inverted U-shaped groove 10A is mounted, and this groove 10A and the glass panel 9
The adhesive 11 is injected into the gap portion as an adhesive layer.

The adhesive 11 is applied from one side X and the other side Y to the syringe G.
Inject as indicated by arrow H, but at this time, glass panel 9
Since it is not possible to check whether the adhesive 11 has entered the upper end 9a, a hole 10a is provided through the upper surface of the guide frame 10 and the bottom of the groove 11a, through which the state of the adhesive 11 can be checked. The reason why it is not possible to confirm the intrusion of the adhesive 11 here is that the guide frame 10 is a strength member and is made of a material that cannot be seen through, and that the groove 10A is in an inverted U-shape and the bottom cannot be seen visually. ,for example,
If the adhesive 11 does not reach the upper end 9a of the glass panel 9, the reliability and reliability of the bonding strength will be significantly reduced. However, 1. By providing the hole 10a, the adhesive 11 can enter the upper end 9a while performing the adhesion work. Furthermore, when the adhesive 11 is strongly pushed in from the direction of arrow H, the adhesive 11 is pushed into the hole. It is clear that the adhesive can be reliably bonded because it comes out as shown by arrow J via 10a.

Note that if there is no hole 10a, it would be necessary to calculate the volume of the adhesive layer and adjust the injection amount of the adhesive 11, which is a troublesome management process, but the present invention has the advantage that this is not necessary at all.

〔Effect of the invention〕

Advantageous Effects of Invention According to the present invention, the bonding work between the glass panel of the railing of the passenger conveyor and the guide frame can be made more efficient, and the reliability of the bonding strength can be improved.
