Description

Description: TECHNICAL FIELD The present invention relates to a balustrade of a passenger conveyor, and more particularly to a balustrade of a passenger conveyor suitable for improving maintainability, assembly and strength.

[Conventional technology]

In a conventional balustrade of a passenger conveyor, it is generally composed of a handrail that is connected endlessly and moves in synchronization with a step, and a balustrade panel that supports the handrail and forms side walls on both sides of the step. However, recently, the design expression with a sense of openness, which maximizes the transparent area of the glass panel used for this balustrade panel, has become popular.

For this reason, the guide frame for guiding the handrail provided on the periphery of the glass panel tends to be reduced in height to the utmost limit. As a conventional example, JP-A-57-180583 or JP-A-55-151769 is used. Parapet structures such as bulletins are known.

Among the conventional balustrade structures, the one in which the peripheral edge of the glass panel and the guide frame are fixed by screws that penetrate the cut part cut in the glass panel is the hand between the entrance and exit doors. If passengers intentionally put weight or baggage weight right above the handrail on the rail road, it is feared that a metal body (such as a screw) may come into contact with the cut portion and damage the glass panel. It was

On the other hand, in the structure in which the fixing between the guide frame and the glass panel is released by screwing the screw, there is a risk that the glass panel may be damaged by the screw for releasing.

A problem common to the above-mentioned conventional structures is that it is difficult to dismantle guides and guide frames that are worn out when the handrail is turned over and need to be replaced frequently over time (especially in the latter case, it takes time to disassemble. ) The structure has the disadvantage that it is difficult to disassemble and easy to assemble as well as maintainability.

[Problems to be Solved by the Invention]

In the balustrade of the conventional passenger conveyor, there is a problem that a load may be applied to the handrail or the glass panel may be damaged when the guide frame is attached or detached, which makes maintenance and assembly difficult.

An object of the present invention is to provide a balustrade of a passenger conveyor which is excellent in maintainability and assemblability without reducing the transparent area of the glass panel.

[Means for Solving the Problems]

In order to achieve the above object, the balustrade of the passenger conveyor according to the present invention, a guide frame is attached to the peripheral edge of the glass panel, a sliding guide is attached to this guide frame to guide and support the handrail, In the balustrade of the passenger conveyor whose peripheral edge is located inside the handrail, the guide frame is formed by a detachable guide frame that is attachable to and detachable from the glass panel at a portion facing the handrail reversing portion. The portion other than the portion is formed by a fixed guide frame fixed to the glass panel, and the removable guide frame and the fixed guide frame are positioned over the joint between the removable guide frame and the fixed guide frame. The sliding guides are connected together.

The attachment / detachment guide frame may have a pair of fixed legs extending over the peripheral edge of the glass panel, and a fastener may be provided to fasten each of the fixed legs to the glass panel.

Further, the fixing guide frame may have a pair of fixed legs extending over the peripheral edge of the glass panel, and each fixed leg may be bonded to the glass panel with an adhesive.

Further, the fixing guide frame may be configured to include a pair of fixing legs having a holding force for holding the glass panel from each side across the peripheral edge of the glass panel.

The detachable guide frame may have a lower end portion connected to the balustrade structure.
