る。 Recent passenger conveyors tend to have longer transport routes, and in this case, it takes a considerable amount of time to get off the passenger conveyor.
There is a need to improve serviceability by shortening the time passengers spend on the conveyor. Therefore, near the entrance of the passenger conveyor, the treadle, or pallet, moves at a slow speed so that passengers can board safely, and as it approaches the middle part, the speed gradually increases, and in the middle part, the treadle (pallet) moves at a constant high speed. An intermediate high-speed passenger conveyor system has been proposed in which the passenger conveyor moves and gradually decelerates as it approaches the exit, and near the exit the tread moves at a slow speed so that passengers can get off safely.

You will be moving at a constant speed that is faster than the speed at the range. Furthermore, in the range of the transmission section 4f of the inner rail 4 on the side of the exit 13b, that is, in the range where the distance between the outer rail 3 and the inner rail 4 gradually increases in the direction of movement of the pallet 10, as shown in FIG.
Since the angle formed by the inner link 9a and the outer link 9b of the folding link mechanism 9 gradually becomes smaller, the speed of the pallet 10 is gradually reduced. Furthermore,
As shown in FIG. 3, in a range where the distance between the outer rail 3 and the inner rail 4 near the exit 13b is wide and constant, that is, in the range of the low-speed straight section 4b of the inner rail 4, the distance between the inner link 9a and the outer link 9b is Since the angle formed is small and constant, the pallet 10 moves at a slow constant speed similar to the above-described side of the entrance 13a. Going further, inner and outer rails 3,
The folding link mechanism 9 is reversed at the reversing portions 3a and 4a of No. 4 and advances in the direction of arrow B in FIG. Since the interval between the lower straight section 3b of the outer rail 3 and the high-speed straight section 4b of the inner rail 4 is the same as the interval between the upper straight section 3a of the outer rail 3 and the high-speed straight section 4b of the inner rail 4, the bending occurs. The moving speed of the link mechanism 9 becomes the same as the moving speed of the upper straight portion 3a,
Endless chain 12 located below the drive device 12
f and the hook 12g drive the folding link mechanism 9 that moves in the B direction. That is, the bending link mechanism 9 is driven at two locations by one drive device 12.

設けることが望ましい。 As mentioned above, the moving speed of the passenger conveyor device of this embodiment and the speed change rate in the speed change range are all adjusted by the distance between the outer rail 3 and the inner rail 4. Then, the entrance 13a and the exit 13
The speed at which passengers can safely get on and off near b, the speed change rate within which passengers can maintain their posture in the speed change range, and the speed at which passengers can be safely transferred in the intermediate or high-speed range are determined by the outer rail 3. and the distance between the inner rails 4 and the rotational speed of the drive device 12. In addition, the position of the acceleration/deceleration area is a position that has enough time for the posture of the passengers who have boarded the intermediate high-speed passenger conveyor 1 to become stable, that is, a position that allows a certain period of low-speed movement corresponding to the low-speed straight section 4c of the inner rail 4. It is desirable to provide an appropriate range and an acceleration area, and the deceleration area is such that the passenger reaches the exit 13b after deceleration is completed, so that the passenger can reach the exit 13b after reaching a stable posture. It is desirable to install it at a location where there is a constant low speed range for recovering one's posture.

ことができる。 Furthermore, the pallets 10 that are adjacent to each other are connected to the engager 11c consisting of a roller of the engagement mechanism 11 and the pallet 1.
Since the engaging surface 10c of the pallet 10 and the sliding member 10i are configured to slidably engage with each other, the load of the passengers on the pallet 10 is always supported by the shaft 6. The structure can be simple and the length of the pallet can be minimized.

ある。 As explained above, the present invention provides an intermediate high-speed passenger conveyor system configured to increase the distance between the outer and inner rails near the entrance and exit and change the overlapping dimension of adjacent pallets to reduce the speed. , the base end of the pallet is pivotally connected to a connecting shaft of a folding link mechanism that is driven to run along the conveyor conveyance path, to which a guide roller that engages in the outer rail is pivotally attached, and the pallet is placed on the adjacent pallet. The distal end side that overlaps with the pallet is held movably in the transport direction by the engagement shaft provided on the coupling shaft that pivotally supports the proximal end of the adjacent pallet, so that the pallet can be stably and reliably supported by the folding link mechanism. In addition, the supporting means has a simple structure, and the change in moving speed of the pallet due to changes in the expansion and contraction of the folding link mechanism can be made smooth and stable. This has the effect that the pallets can be held easily and reliably, ensuring the safety of passengers.
