Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a handrail for a passenger conveyor such as an escalator-1 motorized road, and in particular improves a guide frame for guiding a handrail provided on a glass panel constituting the handrail. Regarding the railing of the passenger conveyor.

[Background of the invention]

The main structure of a conventional passenger conveyor is shown in Figure 3.
Step 1 of transporting passengers by connecting them in an endless manner. It is constructed of a moving body such as a substantially C-shaped handrail 2 that rotates in synchronization, a fixed body such as a parapet 3, and a main body frame 4, and is mounted on a building floor F. The handrail 3 guides the handrail 2 as shown in FIG.
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 upper end of the glass panel 5 is protected by a protective gasket 5a, and a guide frame 6 having a substantially U-shaped groove 6A is mounted thereon, the details of which are shown in FIG. Furthermore, a fixing bolt 8, a clamping plate 8a, a screw plate 8b, a hollow cylinder 89, etc. are arranged at a position that coincides with the notch 5b. Note that this notch 5b is appropriately arranged in the longitudinal direction of the glass panel 5, and the fixing bolt 8 is inserted into the clamping plate 8a, hole 6b, and hollow strip 8c (actually passing through the notch 5b) as shown by arrow A. By inserting the screw into the screw plate 8b, the thickness W of the upper end of the glass panel 5 is adjusted to the groove 6.
At A, grip firmly from the directions of arrows B and C. 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 6C.

This balustrade structure efficiently stores 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, making it popular as a highly transparent passenger conveyor. are collecting.

However, as shown in FIG. 5, the balustrade 3 has a large number of large and small parts, so there is room for improvement in terms of cost and assembly work. Furthermore, in recent years, the thickness h of the handrail 2 has tended to become smaller due to the trend toward light design, and the handrail guide members such as the guide frame 6 have been
Some have a structure in which they are slightly protruded from the bottom surface (No. 4, Y part) to ensure fixing strength.

[Purpose of the invention]

An object of the present invention is to provide a handrail for a passenger conveyor in which the number of parts of the handrail guide member is reduced and passenger safety is improved in a handrail structure in which the handrail guide member slightly protrudes from the lower surface of the handrail 2. be.

[Summary of the invention]

The present invention provides a handrail having a substantially C-shaped cross section and an opening, and a handrail guide member such as a guide frame provided in an area slightly protruding from the lower surface of the handrail. , this guide frame includes a guide part for guiding the handrail, an inverted U-shaped groove part into which the upper end of the glass panel is fitted, and a groove part in the width direction perpendicular to the surface of the glass panel with dimensions approximately equal to the width of the opening of the handrail. The guide frame is made of a long product made of polymer resin, and the groove of the guide frame and the upper end of the glass panel are bonded with adhesive.

[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, guides 7, etc. at the upper end of the glass panel 9 of the present invention, which corresponds to the conventional glass panel 5; The structure is such that a guide frame 10 having a U-shaped groove 10A is placed thereon, and the gap between the groove 10A and the glass panel 9 is used as an adhesive layer and an adhesive 11 is injected into this to fix it.

Here, the guide frame 10 is made of nylon 6 series.

The guide portion 10a has a width approximately equal to the width of the inner circumference of the handrail 2. The guide portion 10a has a width approximately equal to the width of the inner circumference of the handrail 2. a portion 10 that has a portion 10 that passes through the opening of the handrail 2;
b has a narrow width W2, and the lower side 10c protruding from the lower surface of the handrail 2 has a width W which is approximately equal to the opening width, and protrudes in a direction perpendicular to the side surface of the glass panel 9 (W, -W,) are doing. Furthermore, a recess 10d is formed in the center of the width of the guide frame 10, so that it is possible to easily check the dimensions in the left and right direction (balustrade width W) when installing the parapet parts that stand upright on both sides of the step 1. It has become. Further, the adhesive 11 used is a silicone sealant that has adhesive strength, is flexible, and does not damage the glass panel 9.

Note that the width W1 of the guide frame 10 is the width W1 of the handrail 2.
The reason why the guide frame 10 and the handrail 2 are set to be smaller than the opening width is to prevent the guide frame 10 and the handrail 2 from coming into contact with each other at the lower side X, and to prevent the guide frame 10 and the handrail 2 from coming into contact with each other at any part other than the inner periphery 2 where they normally come into contact. This avoids an increase in running resistance due to Further, the reason why the lower side portion 10c of the guide frame 10 is made wide W, (W.>Wl) is based on the idea of personal protection to avoid the passenger's hand from entering the opening of the handrail 2.

By adopting the above parapet structure, significant improvements can be made in terms of reducing the number of parts, improving installation ease, and increasing safety.

〔Effect of the invention〕

According to the present invention as described above, there are advantages in that the number of handrail guiding members can be significantly reduced and passenger safety is improved.
