The transport chain 40 includes an abutment piece 41 attached midway to the bottom of the step body 10 so as to be able to abut from the rear side.

Further, as shown in FIGS. 10 and 11, the inner horizontal and horizontal moving parts (top and bottom horizontal moving parts A in FIG. 10) A, B of the step 8 are lowered downward. A load transmission chain 42 for transmitting the load on the start or descend end side as the ascending force of the step on the rise end or rise start side is arranged. That is, the load transmitting chain 42 is endlessly wound before and after the horizontal moving portions A and B, and in the middle of the winding, the abutting protrusion (not shown) to the step body 10 is shown. Are provided at predetermined intervals, and are provided in such a way that the abutting projections abut the rear or front end of the step body 10 only at the front and rear positions. Incidentally, 43 is a sprocket for guiding the load transmitting chain 42. Also, the main link 17 of the inner chain 13A
A side guide roller 45 guided by an inner guide surface 44 provided along the movement path is provided in the. Further, in the horizontal movement portions A and B of the movement path, the step body 10 is made to pass below the floor surfaces 6 and 7, and a person can get on and off at this portion. . Of course, the handrail 46 is driven by a motor in synchronism with the step 8 and is made to dive under the floors 6 and 7 when a person gets on and off.

In the above structure, when each of the steps 8 is moved in the predetermined direction by the drive chains 13A and 13B, the step 8 is moved to the cylindrical wall surface 4
After spirally ascending along the ascending movement section C,
After passing through the upper horizontal moving portion A, the moving portion moves to the lower moving portion D, and then passes through the lower horizontal moving portion B and again rises to move circularly. Therefore, the same escalator device 1 can have both an ascending function and a descending function. Also, the descending moving part D
At the location from the horizontal movement portion B to the horizontal movement portion B, as shown in FIG. 12, the engagement between the drive chains 13A, 13B and the step body 10 is switched from the rear engagement pin 14B to the front engagement pin 14A by the switching means.

The horizontal movement part B absorbs the difference in length between the drive chains 13A and 13B on the inner take-in end side. Then, at the location where the step moving section C is moved, the inner space between the step body 10 is reduced and the sub link 18
The rear end side of the vehicle rides over the mounting shaft 31 and its engaging groove 32
It engages with 31 and rises. In addition, when moving from the ascending movement unit C to the descending movement unit D through the upper horizontal movement unit A, the same operation as above is performed.

Further, at the start end and the end of the horizontal moving parts A and B, the connection between the main link 17 and the sub link 18 of the inner chain 13A is released, so that the ascending side is the outer drive chain 13
Since it is driven only by B, a large force acts on the outer chain 13B. However, since the load on the descending side is always transmitted to the step body 10 on the ascending side as an ascending force by the load transmitting chain 42, the above-mentioned drawbacks are eliminated.

EFFECTS OF THE INVENTION As described above, according to the configuration of the present invention, the upper part of each step is lifted along the predetermined moving path by the drive chain through the engaging member, and the lower part of each step is moved by the lower guide member. Since it is circulated, the same escalator device can have both the ascending function and the descending function. Therefore, it is much more economical than the conventional case where separate escalator devices are provided for ascending and descending. To be the target. Further, since the step is spiral and moves slowly, it is possible to enjoy the scenery more than the elevator device.

Also, since the engagement position between the step and the drive chain can be switched at the top and bottom of the movement path, the engagement position between the step and the drive chain should always be closest to the floor side of the movement path. Therefore, even if the engaging member is provided on the side portion of the step, the exposed portion of the drive chain can be covered with the side surface of the step, which is safe and looks good.

Further, in the horizontal moving parts at the top and bottom of the circular movement path of the step, the predetermined links of the inner drive chain for driving and guiding the inner end side of the step are configured to be detachable from each other. No problem occurs when moving to the horizontal moving unit or from the horizontal moving unit to the spiral moving unit.

Further, a load transmission chain for transmitting the load at the start or end of the descending side as the ascending force of the step at the end of ascending or ascending start is provided below the horizontal moving part in the movement path of the step, so that the horizontal movement is possible. Even if the link between the links of the inner drive chain is broken at the portion, it is possible to prevent an unreasonable force from acting on the outer drive chain.
