Abstract

PROBLEM TO BE SOLVED: To simplify a structure, and automatically adjust it by providing guide rails set by changing a width interval in a prescribed zone and a link body by connecting a guide roller and a guide roller of an adjacent pallet to each other in a plane rhombic shape through an intermediate pivotally fixing part. SOLUTION: A pallet 3 is connected in a rhombic shape to an adjacent pallet 3 by mutually pivotally fixed four links 4. Pivotally fixing parts 6 and 6 of both side parts follow a width change in guide rails 7 and 7. A width of the guide rials 7 and 7 is formed so as to become gradually narrow in an accelerating zone S1, and in the links 4, the pivotally fixing parts 6 and 6 of both side parts are moved inward, and the links 4 become an opening type rhombic shape, and are put in an accelerating condition after an interval between the pallets 3 and 3 expands. In a high speed zone S2, a width interval of the guide rails 7 and 7 continues still in a narrowed condition. In a decelerating zone, a width of the guide rails 7 and 7 is formed in a expanding structure, and the links 4 become a narrowing type rhombic shape, and the pallets 3 are put in a decelerating condition.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a passenger conveyor such as a moving walkway or an escalator, and more particularly to a variable-speed passenger conveyor in which a moving speed of a pallet (tread surface) changes between a doorway and an exit.

[0002]

2. Description of the Related Art Recently, many passenger conveyors for transporting passengers without walking have been installed at airports, train stations, tourist facilities, and the like.

The speed of the conventional passenger conveyor is generally constant at a constant speed from the entrance to the exit. Entrance and exit are approximately 40 to ensure safety when passengers transfer.
The speed must be less than m / min. At this speed, the speed from the entrance to the exit is constant.

[0004] However, with regard to passenger conveyors installed for use in urban transportation and the like, long-distance types have emerged, and there is a strong demand for speeding up the transport speed in the middle.

[0005] In view of the above, at the entrance, the speed is gradually increased, the speed is gradually increased in the middle, and the speed is gradually increased. A variable-speed passenger conveyor has been proposed, but a variable-speed passenger conveyor with a variable pallet spacing is mainly used.

However, the technology disclosed in the above-mentioned publication has the following problems. (1) The structure is complicated, the space occupied by the structure below the pallet is large, and there is a problem that the equipment cost is high. (2) Since it is a flexible belt link, it is difficult to set the pallet interval with high accuracy, and the belt is protruded during driving, resulting in poor ride comfort. (3) Since the belt link is a flexible belt link, it must always be operated under a tensile load, and the structure does not function if the tensile force is small or the load is a compressive load.

[0008] It is an object of the present invention to provide a variable speed passenger conveyor that is structurally simple and can be adjusted automatically.
