Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a handrail guide for a passenger conveyor.

Conventionally, as this type of apparatus, those shown in FIGS. 1 to 4 are known. In the figure, 1 is a step of the passenger conveyor, 2 is a handrail frame provided along both sides of the step 1, and 3 is a C-shaped cross-sectional surface arranged endlessly along the periphery of the handrail frame 2. The handrail belt is driven at approximately the same speed as step 1 by a drive mechanism (not shown). Further, reference numeral 4 designates horizontally rotatable guide rollers arranged along the top of the handrail frame 2 and alternating with flat handrail guide plates 5, which are used for curved escalators, long conveyors, etc. as shown in the figure. In addition, it fits into the recess on the back surface of the handrail band 3 together with the handrail guide plate 5 to guide the lateral movement of the handrail band 3, and plays the role of reducing the running resistance of the handrail band 3. In addition,
Needless to say, the flat guide plate 5 is provided to suppress the vertical movement of the handrail band 3 and prevent it from coming off outward. In the figure, 6 and 7 indicate the floor.

By the way, in order to attach the handrail strip 3 to the handrail frame 2 during installation of the passenger conveyor having the above configuration, the handrail strip 3 shown in part A of FIG.
At the upper inverted portion, the end of the handrail band 3 is fitted into the handrail frame 2, and is pushed downward along the handrail frame 2. In other words,
It is necessary to push and guide the end of the handrail band 3 pushed in from the above-mentioned section A along the entire periphery of the handrail frame 2.

However, since the guide portion of the handrail frame 2 that guides the end of the handrail strip 3 is composed of the flat handrail guide plate 5 and the guide rollers 4 arranged alternately as described above, As shown in FIG.
The end of the handrail band 3 that is pushed forward is likely to fall down, and especially when the end of the handrail band 3 collides with the end face of the handrail guide plate 5, its forward movement will be blocked. Therefore, each time the handrail strip falls, it becomes necessary to spread the 3 ends of the handrail strip with a tool or the like and attach it to the guide mechanism.
Not only does this work require a lot of effort, but there is also the risk of damaging the handrail strip 3 and the handrail frame 2.

The present invention was developed in view of the above points, and by configuring the end face of the handrail guide plate adjacent to the guide roller into an arc shape along the guide roller, the handrail guide plate and the guide roller can be connected. narrow the gap,
The work of attaching the handrail band to the handrail guide frame is facilitated by smooth pushing and guiding of the handrail band.

An embodiment of the present invention will be described below with reference to FIGS. 5 and 6. In the figure, 4 is a guide roller that is in contact with the concave part on the back surface of the handrail strip 3 and rotates freely as described above, 5 is arranged in parallel with the guide rollers alternately,
A guide plate that fits into the recess on the back surface of the handrail band 3 to support and guide it, and an end surface portion adjacent to the periphery of the guide roller 4 is formed in an arc shape, and the guide roller 4 and the guide plate It is shaped so as to reduce the gap E with 5. Further, 3a and 3b are ear portions indicating the bent ends of the handrail band.

However, since the present invention is constructed as described above, as is clear from the comparison between FIG. 4 and FIG. is prevented as much as possible, the handrail band can be smoothly pushed forward, and it can be easily attached to the handrail frame.
