BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an escalator in which a transfer body is stepped in an inclined section and an inclined passenger conveyor such as an electric road where no step is formed in the transfer body. The present invention relates to a tilt type passenger conveyor suitable for a vehicle.

[0002]

2. Description of the Related Art For example, as shown in FIGS. 6 and 8 of Japanese Patent Publication No. 56-38503, a configuration for reducing the installation width of an inclined passenger conveyor has already been proposed.

[0003]

According to the above prior art, the handrail drive mechanism is installed on the inclined portion of the frame, so that the handrail drive mechanism and the frame are overlapped and installed.
The installation width of the passenger conveyor can be reduced. However, when the handrail drive mechanism is installed on the inclined portion of the frame, if the balustrade is a transparent type, a cover or the like that covers the handrail drive mechanism is installed up to the upper part of the frame, so the transparent part However, there is a problem that the height dimension of the conventional technology becomes narrow, and the application of the above-mentioned conventional technology to an actual machine has been postponed.

[0004] It is an object of the present invention to provide an inclined passenger conveyor that can reduce the installation width without reducing the height of the transparent part of the transparent balustrade by the handrail drive mechanism and can also be used for the opaque balustrade. To provide.

[0005]

In order to achieve the above object, the present invention provides a second inclined portion between the upper horizontal portion and the inclined portion of the frame, the second inclined portion being inclined more gradually than the inclined portion. The handrail drive mechanism is installed on the inclined part, and the vertical projection of the second inclined part and the handrail drive mechanism are overlapped with each other.

By providing the second inclined portion as described above, the height of the frame at that position is reduced, and the handrail drive mechanism is installed using the reduced height. Therefore, it is not necessary to extend a cover or the like covering the handrail drive mechanism to the upper part of the frame, and as a result, it is not necessary to reduce the height of the transparent portion of the transparent balustrade. In addition, even if the height of the frame is partially reduced, a decrease in altitude is within an acceptable range, compared to a configuration in which a part of the frame is cut out and a handrail drive mechanism is disposed there. There is no problem in normal use.
