- a drive means 132 which is horizontally adjacent to the carriage 131, is fixed to the base 130.
- the driving means 13 2 is connected to a screw rod 13 3 screwed to the carriage 13 1, and the other end of the screw rod 13 3 via a reduction mechanism 13 4.
- the height dimension Ht of the engagement device 1 292 A is within the vertical distance Hu between each step 2 on the outward path and each step 2 on the return path, as shown in FIG. Therefore, each step 2 is installed within the range of the width dimension Ws.
- the drive motor 13 5 of the drive means 13 2 is driven to rotate the screw rod 13 3, and the bogie 13 1 is moved to the specific step group 100 Move to the passing position side of 1 2 3 and make rack 1 2 8 correspond to the passing position of sockets 1 2 1 to 1 2 3. Then, when it is detected that the rack 128 is located at the passing position of the sprockets 121 to 123, the operation in the wheelchair transfer mode is started.
- the sprockets 121 to 123 projecting below the specific step group 100 move relative to the track 128. They are interlocked one after another by the movement, rotate by the force generated by this relative movement, and drive the connecting means 1 18, 1 19 and the car stop 1 20 via the power transmission mechanism 124-126. I do.
- the connecting means 118 and 119 are connected to the steps of the adjacent step 2 of the lower step.
- the normal step 2 has the same steps as the adjacent upper and lower steps 2.
- the upper step 101, the middle step 1102, and the lower step 103 are the steps 1101, F102, F102 and F103, respectively.
- the steps 1 0 2 of the middle step 1 0 2 and the lower step 1 0 3 F, 103 F is supported movably in the vertical direction and the tread depth direction with respect to the step frame 102 W, 103 W, so that the step frame 102 W, 103 W It is lifted upward to hold a horizontal wheelchair mounting surface.
- the raised steps 1102F and 103F become the step frames 102W and 103W. Return to the normal position.
- the engaging device 1 is installed in the space between the outward and return paths of the steps 2, 101 to 103 in the upper-floor flat section 1 1.
- 29B mark 1 27 is already waiting on the passing position of steps 101 to 103 R for steps 101 to 103, and the sprocket for specific step group 1 ⁇ 0 Engage with 1 2 1 R to 1 2 3 R.
- the sprockets 121 R to 123 R rotate due to the force generated by this engagement and relative movement, and the connecting means 118, 122 through the power transmission mechanism 124 to 126 R. 1 1 9 and stop 1 2 0 Drive in reverse direction.
- the connecting means 1 18 and 1 19 are pulled out from the lower side of the adjacent tread and returned to the original position, so that each tread 1 0 1 F, 1 0 2 F and 1 0 3
- the connection of F is released, and the bollards 120 retreat from the protruding treads 103 and return to their original positions, so that each step 101, 102, 103 It looks the same as the appearance of normal steps 2 (Fig. 13).
- the wheelchair user or attendant must release the wheelchair brake when the specific step group 100 advances and approaches the upper floor 1 108 of the upper floor flat 11. You can get on the floor 108 and get off on the upper floor.
- the wheelchair-compatible sprinter device 1 may temporarily stop driving, or may continue to operate without stopping.
- the wheelchair 1 4 2 When transporting from the floor to the lower floor, the upper-level flat part 11 1 side engaging device 12 9 B moves the rack 12 27 from the disengaged position to the sprocket 1 2 1 R to 1 2 3 R To the passing position.
- the lower step 103 of the lower step 103 which is the leading end of the specific step group 100, passes through the position of the rack 127, it engages with the rack 127.
- the operation of retracting the boom 120 during ascending operation is now This is an operation to protrude 120.
- the specific step group 100 is stopped so as to be connected to the upper getting on / off floor 1 08 with the wheel stop 120 protruding. If stopped, put in wheelchair 1 4 2 ⁇ Wheelchair 142 can be safely driven up to the tip of the wheelchair mounting surface because the wheelchair 120 has already protruded.
- the sprockets 122 2 R and 122 R of the middle step 110 2 and the upper step 101 are sequentially Drive the connecting means 1 19, 1 18 by engaging with the rack 1 27, and connect the three treads 1 0 1 F, 1 0 2 F, 1 0 3 F to maintain the horizontal state .
- the wheelchair mounting surface is configured by connecting a plurality of special steps.
- the present invention is not limited to this.
- a single special step forms the wheelchair mounting surface. It is good also as a structure which performs. Even in the case where such a drive mechanism is provided, in this embodiment, the size of the drive sprocket 62 and the driven sprocket 71 can be freely selected. By ensuring sufficient space to provide 29 B, it is possible to realize an escalator device having a small thickness in the escalator device 1 for wheelchairs.
