Next, when the conveyor belt 6 moves and the steps 12 for the inclined wheelchair approach the entrance 4 on the upper end 3 side, the case where the steps 12 rise from the entrance 4 on the lower end 2 side of the main frame 1 The steps 12 and the like operate.

That is, the first operating mechanism 24 on the upper end 3 side of the main frame 1 operates to raise the engaging mechanism 26. Then, when the inclined wheelchair step 12 approaches the position of the first operating mechanism 24 on the upper end 3 side of the main frame 1, the inclined step plate 14 held in the inclined posture by the inclination roller or the like returns to the horizontal position. Next, when the tilting mechanism 13 of the inclined wheelchair step 12 is engaged with the engagement mechanism 26 that has been lifted and braked by the first operating mechanism 24, the tilting mechanism 13 is driven by the movement of the transport belt 6, and the tilted tread plate 14 is moved. Are held in the horizontal position, and the state shown in FIG. 10 is obtained.

The engagement mechanism 26 of the first operating mechanism 24
Is temporarily disposed from the ascending position to the descending position. Further, the transport belt 6 is operated to move up, and the second wheelchair step 18 moves to the gradually decreasing inclination moving section. Then, as shown in FIG. 11, the first wheelchair step 15 is moved relative to the base of the second wheelchair step 18.
The first wheelchair step 15 faces the first operating mechanism 24 in a state in which the step surface of the first wheelchair rises.

In this state, the second wheelchair step 18
Faces the second operation mechanism 27. In this state, the position of the inclined step board 14 is arranged at a position where approximately 30% of the length along the length of the main frame 1 projects from the tip of the comb 5. In this state, that is, the state shown in FIG. 11, the transport belt 6 stops, and the wheelchair 22 descends from the wheelchair loading surface 23 to the entrance 4 on the upper end 3 side.

Then, in this state, the engaging mechanism 26 of the first operating mechanism 24 rises and meshes with the advance / retreat mechanism 16 of the first wheelchair step 15 as shown in FIG. In addition, from the state shown in FIG. 11, the first drive mechanism 29 of the second operating mechanism 27 rises and engages with the transmission mechanism 32 of the second wheelchair step 18, resulting in the state shown in FIG.

As a result, the ascending step plate 19 of the second wheelchair step 18 is supported by the rollers 30 of the support plate 31 of the first drive mechanism 29, and the first operating mechanism 24 operates to mesh with the engaging mechanism 26. The advancing / retreating mechanism 16 of the first wheelchair step 15 is driven to retreat the connecting arm 17, and the engagement of the second wheelchair step 18 with the raised step board 19 is released.

Next, the first drive mechanism 29 of the second operating mechanism 27 operates to lower the elevating mechanism 28, and the ascending step board 19
Is lowered with respect to the base of the second wheelchair step 18 as shown in FIG.
As shown in FIG. 7, the first wheelchair step 15 is disposed and held at a position lowered with respect to the tread surface. At this time, the descending operation of the ascending step board 19 is regulated by the regulating means 33, that is, the guide pin 36 is guided in the guide groove 34, so that the ascending / descending path is regulated.
Is lowered so as to maintain a substantially constant small gap in the gap with the riser.

The first driving mechanism 2 of the second operating mechanism 27
9 operates with the transmission mechanism 32 of the second wheelchair step 18 engaged with the transmission mechanism 32 of the second wheelchair step 18.
Is driven, and the vehicle stopper piece 20 is lowered and held at the lowered position, and the state shown in FIG. 13 is obtained. Next, the first operation mechanism 2
The fourth and second operating mechanisms 27 are respectively arranged at the lowered position, and the escalator with the wheelchair step returns to the normal operation.

The case where the wheelchair 22 is transported from the entrance 4 at the lower end 2 to the entrance 4 at the upper end 3 has been described above. However, when the wheelchair 22 is transported from the entrance 4 on the upper end 3 side to the entrance 4 on the lower end 2 side, the detailed description is omitted, except for the operation of the boarding platform, except for the operation of the platform. Related devices such as the operation mechanism 27 are operated in the opposite direction to the time when the wheelchair 22 is transported upward. This allows the wheelchair 22
The same operation as that at the time of ascending conveyance can be obtained.

As described above, one of the first wheelchair steps 15 and the second wheelchair steps 18 moves to the gradually increasing or decreasing slope moving section at any end of the main frame 1. The wheelchair loading surface 23 is formed in a stopped state. Therefore, without providing a horizontal movement section of each step longer than the normal escalator near the end of the main frame 1,
The wheelchair 22 can get on and get off.

Accordingly, it is not necessary to increase the total length of the main frame 1 or to increase the interval between building beams supporting both ends of the main frame 1. Therefore, it is possible to eliminate the restriction on the installation of the escalator with the wheelchair step and the restriction on the modification of the existing normal escalator to the escalator with the wheelchair step.

When the lifting step 19 of the step 18 for the second wheelchair moves up and down with respect to the base of the step 18 for the wheelchair, the lifting operation of the step 19 is controlled by the regulating means 33, that is, the guide groove 34. Since the guide pin 36 is guided, the ascending / descending path is regulated, so that the gap between the first wheelchair step 15 and the riser is displaced vertically so as to maintain a substantially constant small interval.

Therefore, the foreign object is not caught in the gap between the rising step board 19 and the riser of the first wheelchair step 15 during the lifting operation, so that the lifting operation of the rising step board 19 is not hindered, and the wheelchair loading surface 23 can be smoothly moved. It is formed. Therefore, an escalator with a wheelchair step having high operation reliability can be obtained.
